Frequently Asked Questions

For applications requiring simultaneous product weighing and sorting, how does automatic weighing and sorting equipment achieve high-speed, high-precision classification?

The equipment integrates a dynamic checkweigher with sorting mechanisms (such as pushers, air jets, flap diverters, or swing arms). As products pass through the high‑speed weighing section, the load cell completes weight acquisition within an extremely short time (typically 0.1–0.3 seconds) and transmits the data to the controller. The controller then determines the product grade based on preset weight ranges, predicts the arrival time of the product at the sorting point, and triggers the corresponding actuator to divert it into the appropriate lane. By optimizing the weighing filter algorithm, reducing mechanical actuation delays, and employing multi‑stage sorting structures, the system achieves stable sorting of 100–300 products per minute with an accuracy of up to 0.1 g or even higher.

How does the fully automatic insertion/withdrawal force testing equipment ensure precision and repeatability in connector insertion speed, insertion depth, and force measurement?

The equipment is driven by servo motors and ball screws, enabling precise control of insertion/withdrawal speed (e.g., adjustable from 5 to 50 mm/min) and stroke position. The force sensor is mounted on the moving end, with a sampling rate typically exceeding 1000 Hz. Through real‑time data acquisition and peak‑hold algorithms, the system captures insertion force, withdrawal force, and maximum force values. Repeatability accuracy can be verified by repeatedly testing the same standard sample; high‑quality equipment typically maintains repeatability error within ±1%. In addition, the system records the complete force‑displacement curve, which can be used for analyzing contact stability.

What specific improvements does the PVDC solid‑state sealing system offer in terms of lifespan and power consumption compared to traditional gas‑based sealing devices?

Traditional gas‑based sealing relies on gas filling to maintain the sealing effect, which suffers from slow gas leakage, requiring frequent replenishment or replacement of the gas source, and consumes relatively high power. In contrast, the PVDC solid‑state sealing system employs solid‑state media and advanced circuit design, with no moving wear parts inside and extremely low static losses, extending service life by several times compared to older devices. At the same time, its power consumption is significantly reduced, lowering the user's procurement and maintenance costs for consumables (such as desiccants and sealing gases), and reducing production downtime caused by seal failure.

What detection method is commonly used in fully automatic air tightness testing equipment for electronic connectors, and how is reliability ensured in high‑volume testing?

The commonly used methods include differential‑pressure air tightness testing and helium mass spectrometry leak detection. The differential‑pressure method involves filling the product with compressed air at a specified pressure, and after a holding period, measuring the internal pressure drop to determine whether leakage exists. To ensure reliability in high‑volume testing, the equipment is equipped with standard leak samples for periodic calibration, and temperature‑drift compensation algorithms are used to eliminate the influence of environmental temperature variations. At the same time, test data for each product is recorded and linked to a barcode for full traceability.

How does a fully automated van-loading system automatically adapt to cargo compartments of varying lengths and widths while ensuring neat, orderly stacking?

The system’s front end is equipped with a LiDAR or vision sensor that automatically scans the interior of the cargo compartment prior to loading, acquiring data on length, width, and any internal obstructions. The handling mechanism—such as a telescopic belt conveyor or a rail-guided robotic arm—dynamically adjusts its insertion depth based on the distance measurements. Inside the compartment, an automated shaping and positioning unit employs side‑pushing, alignment‑striking, or layered‑compaction devices to ensure each package is tightly arranged according to the predefined stacking pattern. Meanwhile, the control system continuously monitors the current placement and autonomously plans the motion trajectory for the next layer or row.

This technology employs carrier‑communication principles to couple high‑frequency data signals onto the DC power line. With a well‑designed isolation and filtering circuit and proper load matching, it can simultaneously provide stable power and reliable data communication to multiple slave devices over distances of several hundred meters. Signal quality depends primarily on line impedance and interference‑suppression performance; specially engineered bus couplers paired with terminating resistors effectively minimize reflections and noise, meeting the demanding requirements of industrial field control applications.

Such equipment typically features a flexible manufacturing design, with key workstations equipped with programmable, adjustable positioning fixtures, parameterized crimping or welding modules, and automated material‑feeding systems. When switching product specifications, operators retrieve pre‑stored process recipes—such as dimensional parameters, pressure thresholds, and temperature profiles—from the control system; the equipment then automatically adjusts the gripper stroke, the vibratory bowl’s sorting track, and the vision‑inspection template. The entire changeover time can be kept within a few to several tens of minutes, eliminating the need to replace numerous mechanical components.

Does a single‑supply bus communication system, which requires only two wires to provide both power and data transmission, compromise signal quality or load‑carrying capability?

This technology employs carrier‑communication principles to couple high‑frequency data signals onto the DC power line. With a well‑designed isolation and filtering circuit and proper load matching, it can simultaneously provide stable power and reliable data communication to multiple slave devices over distances of several hundred meters. Signal quality depends primarily on line impedance and interference‑suppression performance; specially engineered bus couplers paired with terminating resistors effectively minimize reflections and noise, meeting the demanding requirements of industrial field control applications.

When a fully wireless power and communication control system is deployed on rotating or moving components, how can stable transmission of both power and signals be ensured?

This technology employs electromagnetic coupling or resonant induction to achieve contactless power transfer, while leveraging modulation and demodulation techniques to superimpose control signals onto the power carrier, enabling wireless power delivery and bidirectional communication between the primary and secondary circuit boards. By eliminating the need for slip rings or physical wiring, it avoids contact wear and signal attenuation, making it particularly well-suited for applications such as wind turbine rotors and rotating engine components, where stable sensing and control can be maintained even under harsh environmental conditions and high‑speed rotational regimes.

How does a high-precision dynamic weighing and automatic weight‑correction system achieve real-time weight feedback and adjustment during continuous production?

The system uses high‑sensitivity load cells to acquire real‑time weight signals from materials or products. After high‑speed sampling and filtering, these signals are compared with preset target values. When the deviation exceeds the allowable tolerance, the control system automatically issues adjustment commands—such as modifying the feed rate or stroke—to feeding, filling, or forming equipment, thereby achieving closed‑loop control. With a measurement accuracy of up to 0.01 g, the system is well suited for batch production applications that demand stringent weight consistency.

In industries such as petrochemicals and power generation, what advantages do customized PLC or DCS control systems offer over standard‑off‑the‑shelf products?

Standard control systems are suitable for general operating conditions but often fall short of meeting site‑specific requirements for safety interlock logic, signal interfaces, or environmental protection. Customized systems, on the other hand, can be tailored to the actual equipment layout, sensor types, and process‑level interlock criteria, delivering superior system integration, reduced redundant hardware, and more convenient operation and maintenance—thereby enhancing control reliability and field adaptability.
