[0037] Relay testing is a crucial quality control process, primarily used to verify relay performance and reliability under various operating conditions. This testing typically includes electrical, mechanical, and environmental compatibility tests. Electrical testing examines parameters such as the relay's contact resistance, breakout voltage, and make-on voltage to ensure accurate circuit switching.

This test verifies whether the relay contacts can properly close and open, ensuring that they can reliably control the on / off state of the circuit in practical applications. Typically performed using specialized test equipment, this method is crucial for ensuring the reliability of relays in various electronic devices and systems.

[0039] In the related art, manual insertion of the test card into the dynamic and static reeds of the relay is generally adopted. However, such operation is prone to scratches on the reed surface because the insertion position and insertion force are uncontrollable.

[0040] In order to solve the above problems, the utility model proposes a relay card test device, which aims to provide a relay card test device that can control the insertion position and insertion force of the test card to reduce the risk of reed scratches. Figures 1 to 5 The figure is a structural diagram of an embodiment of the relay card test device provided by the present utility model.

[0041] Please refer to Figures 1 to 5 The present invention proposes a relay card insertion test device 1000, comprising a workbench 1, a loading mechanism 2, a card insertion mechanism 3 and an energizing mechanism 4. The workbench 1 is provided with a base 11, and the base 11 is formed with a slide groove 111. The loading mechanism 2 includes a first driving member 21 and a bearing seat 22. The first driving member 21 is arranged along the extension direction of the slide groove 111, and the bearing seat 22 is arranged at the movable end of the first driving member 21 and is slidably limited in the slide groove 111. The bearing seat 22 is used to fix the relay. The card insertion mechanism 3 includes a second driving member 31 and a test card 32 arranged at the movable end of the second driving member 31. The second driving member 31 is arranged on the workbench 1, and the test card 32 is arranged along the moving direction of the bearing seat 22. The test card 32 can be plugged in or out of the relay. The energizing mechanism 4 includes a third driving member 41 and a conductive part 42 arranged at the movable end of the third driving member 41. The conductive part 42 can move in a direction perpendicular to the workbench 1, and the conductive part 42 is used to contact the pin 2100 of the relay to achieve conductivity.

[0042] In the technical solution of the present invention, a relay card insertion test device 1000 and a relay testing device are proposed, wherein the relay card insertion test device 1000 includes a workbench 1, a loading mechanism 2, a card insertion mechanism 3 and a power-on mechanism 4. The workbench 1 is provided with a base 11, and the base 11 is formed with a slide groove 111. The loading mechanism 2 includes a first driving member 21 and a bearing seat 22 provided on the first driving member 21. The bearing seat 22 slides and is limited in the slide groove 111. The relay product to be tested is fixed on the bearing seat 22. The card insertion mechanism 3 includes a second driving member 31 and a test card 32 provided at the movable end of the second driving member 31. The test card 32 is arranged along the moving direction of the bearing seat 22. The test card 32 can be connected to or disconnected from the relay. The power-on mechanism 4 is used to control the power on and off of the relay. During the card insertion test, the first driver 21 moves the relay product, secured to the support base 22, along the slide 111 to a position near the card insertion mechanism 3. At this point, the second driver 31 is controlled to drive the test card 32 into the gap between the relay's moving and stationary reeds. The third driver 41 drives the conductive portion 42 vertically until it contacts the relay's pin 2100. If the relay is turned on, it is considered a good product. Otherwise, if the relay fails to turn on, it is considered a defective product. This automated card insertion test solution precisely controls the second driver 31, eliminating the need for manual card insertion, avoiding the uncontrollable insertion position and force, and thus preventing scratches on the reed surface.

[0043] It should be noted that the bearing seat 22 has a first position and a second position, and the first driving member 21 can drive the bearing seat 22 to flow between the first position and the second position. When the bearing seat 22 is in the first position, the bearing groove 221 on the bearing seat 22 is aligned with the feed channel 113 of the base 11. At this time, the relay to be tested can enter the bearing groove 221 from the feed channel 113 and be fixed in the bearing groove 221; when the bearing seat 22 is in the second position, the bearing groove 221 of the bearing seat 22 is aligned with the discharge channel on the base 11. At this time, the first driving member 21 drives the bearing seat 22 to move until the relay to be tested moves from the axial position of the feed channel 113 to the axial position of the discharge channel. It can be understood that the relay card insertion test performed using the relay card insertion test device 1000 provided in this solution includes the following process steps: S1: the supporting seat 22 is in the first position, and the relay to be tested enters the supporting slot 221 from the feed channel 113 and is fixed in the supporting slot 221; S2: the first driving member 21 drives the supporting seat 22 to move until the relay to be tested moves to one end close to the test card 32; S3: the second driving member 31 controls the test card 32 to be inserted into the gap between the two reeds of the relay to be tested; S4: the third driving member 41 drives the conductive part 42 to move upward until the conductive part 42 contacts the pin 2100 of the relay. If the relay is conductive, the relay is discharged from the good product discharge slot 114 and enters the next process. If the relay is not conductive, the relay is discharged from the defective product discharge slot 115 for recycling.

[0044] In order to control the insertion position of the test card 32 and avoid the test card 32 from being offset and scratching the relay reed, a guide hole 112 is formed on one side of the base 11 close to the test card 32. For details, please refer to Figure 4 Guide hole 112 is positioned directly opposite the relay's moving and stationary reeds. Test card 32 can first be guided through guide hole 112 before being inserted into the gap between the moving and stationary reeds, significantly improving the accuracy and safety of the test. This design ensures that test card 32 can be precisely inserted into the reed gap, avoiding scratches on the reed surface due to improper insertion, thereby reducing physical damage to the relay contacts. Furthermore, the use of guide hole 112 helps reduce errors during the test process, improves test repeatability and consistency, and ensures the reliability of test results. This approach not only protects the relay's mechanical components but also helps extend its service life, while ensuring the efficiency of the test process and the accuracy of test data.

[0045] In one embodiment of the present invention, the base 11 is formed with a feed channel 113 and a discharge channel. For details, please refer to Figure 4The relative positions of the feed channel 113 and the discharge channel are not limited in this solution. In this embodiment, the feed channel 113 is arranged on the left side of the chute 111, and the discharge channel includes a good product discharge trough 114 and a defective product discharge trough 115. Such an arrangement can significantly improve the efficiency and accuracy of the production line. This design enables the relays to be effectively diverted during the processing process, and good products and defective products can be separated and processed through different channels respectively. This not only helps to quickly identify and process unqualified products and reduce the confusion between good and defective products, but also optimizes the subsequent material handling process. For example, good products can directly enter the next production link or packaging, while defective products can be recycled or reprocessed. In addition, this diversion mechanism also helps to reduce the workload of operators, improve the degree of automation of the production line and the overall production efficiency.

[0046] Since the relay is fixed in the bearing slot 221, in order to realize the card insertion test of the relay, the bearing slot 221 is provided with a plug-in slot 222 on one side close to the test card 32. For details, please refer to Figure 5 The test card 32 can be inserted into the gap between the moving and stationary reeds through the insertion slot 222. The insertion slot 222 can provide a secondary guide effect for the test card 32. The inner wall of the bearing slot 221 relative to the insertion slot 222 is formed with an avoidance slot 223. The avoidance slot 223 is used to provide space for the movable test card 32 to be inserted, preventing the test card 32 from colliding with the inner wall of the bearing slot 221 and being damaged. Furthermore, to energize the relay, the bottom of the bearing slot 221 is provided with a plurality of through holes 224. The plurality of through holes 224 correspond to the plurality of pins 2100 of the relay. Since the pins 2100 of the relay extend downward, the pins 2100 are exposed through the through holes 224. The third driving member 41 drives the guide portion to contact the exposed pins 2100, thereby energizing the relay.

[0047] In order to guide the support base 22, the support base 22 is provided with a guide block 225. For details, please refer to Figure 2 , one side of the guide block 225 is in sliding contact with the upper surface of the base 11, and a guide block 225 is added to the movable supporting seat 22. First, the guide block 225 can ensure that the supporting seat 22 moves accurately along the predetermined path during the movement, reducing errors caused by offset or vibration. Secondly, this design helps to protect the supporting seat 22 and related mechanical components, avoiding wear or damage caused by improper movement. In addition, the guide block 225 can also improve the stability of the supporting seat 22, ensuring that it will not tilt or overturn during the movement. Ultimately, this design not only improves the safety and reliability of the operation, but also helps to improve the work efficiency and production quality of the entire system.

[0048] The card insertion mechanism 3 is provided with a connecting frame 33, and the test card 32 is fixed to the movable end of the second driving member 31 through the connecting frame 33. For details, please refer to Figure 1 By placing the card insertion mechanism 3 on one side of the base 11 and utilizing the connecting frame 33 to transmit the movement of the second driving member 31, the overall volume of the device is compressed, thereby reducing its footprint. The test card 32 is mounted on the end of the connecting frame 33 away from the second driving member 31 via the mounting portion 34. The mounting portion includes an upper pressing block 341 and a lower pressing block 342. The upper pressing block 341 and the lower pressing block 342 are pressed together, and part of the structure of the test card 32 is fixed between the upper pressing block 341 and the lower pressing block 342 and secured by bolts. If the test card 32 needs to be replaced, simply loosen the bolts and remove the upper pressing block 341.

[0049] The present invention also proposes a relay testing device, which includes a relay card testing device 1000. The specific structure of the relay card testing device 1000 refers to the above embodiment. Since the present relay testing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
