Description

Technical Field

[0001] This invention relates to the field of relay manufacturing technology, specifically to a batch testing system for electronic relays. Background Technology

[0002] Batch testing of relays is a crucial step in ensuring product quality and reliability. It typically includes inspection of the relay's appearance and structure, thermal cycling testing, and lifespan testing to determine whether the batch of relays meets requirements, obtain the product pass rate, and then allow compliant relays to enter the market.

[0003] For example, in the patent document with application number 202010263757.5, a batch testing system for the production of electronic relays is disclosed, and a device for inspecting the appearance of relay products is specifically disclosed, which discloses a device for inspecting the contact angles of relays to determine the pass rate of the contact angles of relay products.

[0004] In the above technical solution, using separate equipment to test the appearance conformity of relays is a waste of testing space. At the same time, the loading and unloading of relays need to be considered in this process so that the relays can enter the next testing process. This testing method wastes too many testing resources. Summary of the Invention

[0005] The purpose of this invention is to provide a batch testing system for electronic relays.

[0006] The technical problem solved by this invention is to address the issue of excessive resource waste in relay detection in existing technologies.

[0007] The present invention can be achieved through the following technical solution: a batch testing system for electronic relays, including a conveyor roller, wherein the conveyor roller is driven by a conveyor motor, and a conveyor chain is also provided on the adjacent conveyor rollers. Mounting plates are uniformly fixed on the conveyor chain, and a support frame for uniformly placing relays is fixed on the side of the mounting plate. A transfer mechanism for transferring relays is provided on the side of the support frame.

[0008] A further technical improvement of the present invention is that: a side base is fixed on the side of the support frame, and a detection support base for supporting the relay is snapped onto the side base; a plurality of limit detection holes are evenly opened on the detection support base.

[0009] A further technical improvement of the present invention is that a detection base plate is fixed at the bottom of the support frame, and a number of proximity sensors for detecting the pins are evenly arranged on the detection base plate.

[0010] A further technical improvement of the present invention is that: the transfer mechanism includes an adjustment turntable, the adjustment turntable is installed at the output end of the adjustment motor, a first mounting base and a second mounting base are symmetrically fixed on the adjustment turntable, and a receiving component is respectively provided on the first mounting base and the second mounting base.

[0011] A further technical improvement of the present invention is that: the receiving component includes a transfer cylinder, the output end of the transfer cylinder is fixed with a transfer support base, a U-shaped support frame is fixedly installed on the transfer base, and a support platform for achieving the support function is slidably arranged on the U-shaped support frame by a support spring.

[0012] A further technical improvement of the present invention is that: a longitudinal support seat is fixed on the side of the transfer mechanism, a detection top plate is slidably arranged on the longitudinal support seat, and a detection bottom plate is slidably arranged on the longitudinal support seat.

[0013] A further technical improvement of the present invention is that: a switching contact platform for contacting the relay pins is fixed on the detection base plate, a pressure limiting ring is fixed at the bottom of the detection top plate, and a temperature sensor for sensing the temperature of the relay is fixed inside the pressure limiting ring.

[0014] A further technical improvement of the present invention is that a cooling support is fixed between adjacent longitudinal support seats, and cooling jet outlets are uniformly arranged on the cooling support seats, and the cooling jet outlets are connected to the output end of the cooling circulation equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This application enables continuous operation of relays from loading → visual inspection (pin position) → continuity test → thermal cycle → cooling → re-inspection → unloading by mounting a detachable test support base on a mounting plate on the conveyor chain. This eliminates the time-consuming equipment switching of traditional separate testing. Furthermore, the limit detection holes of the test support base support multiple relays to be installed simultaneously. Combined with the alternating testing mechanism of the first and second stations, the single batch testing cycle is significantly shortened.

[0016] 2. The U-shaped support frame and support spring of the transfer mechanism in this application constitute an elastic support system, which absorbs mechanical vibration when transferring the test support base, and prevents the internal circuit of the relay from falling off due to vibration (especially under high temperature conditions). The temperature sensor is used to monitor the operating temperature of the relay in real time, and the on / off stability is re-tested after cooling to ensure the reliability of the test results.

[0017] 3. This application utilizes the synergistic effect of the contact platform and the pressure limiting ring, along with the internal telescopic rod to control the downward pressure of the detection top plate, ensuring tight contact between the relay pins and the test interface. Simultaneously, the supporting spring adaptively adjusts the pressure to accommodate relays of different sizes. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] Please see Figure 1-7As shown, an electronic relay batch testing system includes a conveyor roller 2 driven by a conveyor motor, and a conveyor chain 3 is also provided on the adjacent conveyor roller 2. The relay equipment is fed by the feeding mechanism 4 and placed on the feeding station of the conveyor chain 3. Then, under the action of the conveyor roller 2 and the conveyor chain 3, the relay equipment is moved until it is moved to the position conversion mechanism 5. The position conversion mechanism 5 moves the relay equipment to the testing equipment for testing. After the testing is completed, the relay equipment is preliminarily processed and transferred to the conveyor chain 3. The conveyor chain 3 moves the relay equipment to the unloading mechanism 1 for unloading, thereby achieving full processing of the relay equipment.

[0023] In the above technical solution, the loading mechanism 4 and unloading mechanism 1 in this application are common robotic arm structures, used to directly place the relay equipment at the installation location of the conveyor chain 3. This application includes four workstations. The first is a loading workstation 6, which works in conjunction with the loading mechanism 4 to load the relay equipment onto the installation location on the conveyor chain 3. The movement of the conveyor chain 3 moves the relay equipment to the first workstation 8 and the second workstation 7. The first workstation 8 and the second workstation 7 work together to ensure the relay testing efficiency. Simultaneously, due to the alternating work of the first workstation 8 and the second workstation 7, there is a certain time interval between each workstation group for cooling the relay equipment. This allows the relay equipment a certain amount of time to cool down after thermal cycling testing, preventing... The vibration generated during the position switching of the relay device under the action of the position switching mechanism 5 avoids the problem of the internal wire connector of the relay falling off under the action of high temperature and vibration, thereby ensuring the accuracy of the relay test results and reducing relay abnormalities caused by the external environment during relay testing. Therefore, it can avoid secondary damage to the relay after testing. The cooling station 9 is used to apply external cold air directly to the relay when the conveyor chain 3 stops at this position to fully cool the relay. After cooling, it is transferred to the cooling test station 10 for testing to determine whether there is a continuity abnormality in the relay after cooling. If not, the relay is transferred to the unloading station 11, where an external robotic arm transfers the relay to the unloading equipment.

[0024] In this application, six sets of mounting plates 516 are evenly fixed on the conveyor chain 3. A support frame 514 is fixed to the side of each mounting plate 516, and a side base 520 is fixed inside the support frame 514. A detection support base 519 is fitted onto the side base 520, and the detection support base 519 is placed into a slot in the side base 520 to limit its installation. To maintain the stability of the detection support base 519, during detection... A counterweight base 521 is fixed to the bottom of the support base 519, and a mounting support plate 518 is fixed on the counterweight base 521. The mounting support plate 518 is provided with a mounting groove 517 for moving the detection support base 519. Limiting detection holes 515 for placing relays are evenly spaced on both the detection support base 519 and the counterweight base 521. Multiple sets of limiting detection holes 515 are provided to allow simultaneous installation and testing of multiple sets of relays. In this application, the relays are evenly placed inside the limiting detection holes 515 on the detection support base 519, enabling uniform feeding of multiple sets of relays. Then, by controlling the position of the mounting support plate 518 (this process can be done using a robotic arm or manually), the detection support base 519 is secured to the side base 520, preventing movement of the detection support base 519. The detection support base 519 is then moved sequentially to different workstations by the movement of the conveyor chain 3.

[0025] Specifically, a detection base plate 522 is fixedly installed at the bottom of the support frame 514. Several sets of proximity sensors 523 are evenly arranged on the detection base plate 522. The proximity sensors 523 are used to determine the position of the relay pin. In use, when the detection support base 519 is placed on the side base 520, the relay pin is placed on the detection base plate 522. The proximity sensors 523 sense the relay pin and mark and record the relay with unqualified pin. The relay will not be further tested to ensure the safety of the detection environment.

[0026] Furthermore, the position conversion mechanism 5 includes an adjustment motor 51, which is fixed on the frame and drives an adjustment turntable 513. A first mounting base 52 and a second mounting base 512 are symmetrically fixed on the adjustment turntable 513. Taking the first mounting base 52 as an example, a transfer cylinder 510 is fixedly mounted on it. A transfer support base 511 is fixed to the output end of the transfer cylinder 510, and a support column 57 is fixed to the output end of the transfer support base 511. This support column 57 engages with a mounting groove 517. Firstly, the adjustment... Motor 51 drives adjustment turntable 513, which moves the first mounting base 52 or the second mounting base 512 to below the support frame 514. Then, the transfer cylinder 510 controls the height of the transfer support base 511, thereby controlling the height of the support column 57. This allows the support column 57 to act on the mounting groove 517, lifting the mounting support plate 518. This separates the detection support base 519 from the side base 520, facilitating the movement of the detection support base 519, which carries a large number of relays, and enabling further batch testing of the relays.

[0027] In this application, in order to enable the relay to transfer more stably, a U-shaped support frame 54 is fixedly installed on the transfer support base 511, and a sliding shaft 53 is fixedly installed on the U-shaped support frame 54. A sliding support frame 56 is slidably arranged on the sliding shaft 53 through a support spring 55. A support column 57 is fixed on the sliding support frame 56. The sliding support frame 56 includes a recess and a support. The recess has a sliding limiting platform 58, which is used to slide and connect with the sliding shaft 53. The support is a support platform 59, which is used to contact the mounting support plate 518. In this application, when the support column 57 initially contacts the mounting support plate 518, the support column 57 limits the mounting support plate 518 until the bottom surface of the mounting support plate 518 contacts the support platform 59. Then, the longitudinal movement of the transfer support base 511 is controlled by the transfer cylinder 510. At this time, the mounting support plate 518 is gradually lifted by the support platform 59, the sliding support frame 56 slides on the U-shaped support frame 54, and the support spring 55 is compressed, realizing a relatively stable transfer of the relay. When the detection support base 519 is transferred and unloaded, the detection support base 519 is easily lifted by the support spring 55, which facilitates the stable transfer of the detection support base 519.

[0028] Simultaneously, a longitudinal support base 526 is fixedly installed at the testing station. A testing plate 528 is fixedly installed on the longitudinal support base 526, and a switching contact platform 527 is provided on the testing plate 528. A testing top plate 524 is slidably installed on the longitudinal support base 526. That is, in use, the height of the testing support base 519 is controlled by the transfer cylinder 510, so that the testing support base 519 is located between the testing plate 528 and the testing top plate 524. Then, the height of the transfer cylinder 510 is controlled to make the relay pins fall onto the testing plate 528. Then, the longitudinal pressure applied by the testing top plate 524 ensures that the relay can stably contact the switching contact platform 527. The circuit is activated to control the relays that can be tested on the switching contact platform 527 for testing, and the test results are sent to the system platform for feedback.

[0029] In the above technical solution, in order to realize the longitudinal movement of the detection top plate 524, a longitudinal slide groove 531 is provided on the longitudinal support seat 526. An internal telescopic rod 534 is fixed inside the longitudinal slide groove 531. A longitudinal slide plate 533 is fixedly installed at the output end of the internal telescopic rod 534. The detection top plate 524 is fixedly installed on the longitudinal slide plate 533. The height of the longitudinal slide plate 533 is controlled by the action of the internal telescopic rod 534, thereby driving the height of the detection top plate 524 so that the detection top plate 524 acts on the top of the relay to support and detect the relay.

[0030] As a further embodiment of this application, a pressure limiting ring 529 for limiting the pressure of the relay is fixed on the top of the detection top plate 524. A temperature sensor 530 for detecting the current temperature of the relay is fixed inside the pressure limiting ring 529. At the same time, a cooling support 525 is fixed between adjacent longitudinal support seats 526, and a cooling air outlet 532 is fixed on the cooling support 525. In this application, the temperature sensor 530 is used to detect the temperature of the relay in real time, and the cooling air outlet 532 connected to the cold air pipe is used to initially cool the relay after detection. In this application, detection after cooling the relay can reduce the possibility of circuit breakage caused by the relay operating in a high-temperature environment and generating vibration. At the same time, since the height of the support platform 59 is adjustable, that is, the compression height of the support spring 55 is adjustable, it is convenient to use the detection top plate 524 to press down the relay, so that the relay can stably act on the on / off contact platform 527, ensuring stable detection of the relay.

[0031] In use, this invention utilizes the movement of the conveyor chain 3 to move each relay device to the first station 8 and the second station 7. The first station 8 and the second station 7 work together to ensure the relay's testing efficiency. Simultaneously, due to the alternating operation of the first station 8 and the second station 7, there is a certain time interval between each station to cool the relay device. This allows the relay device sufficient time to cool down after thermal cycling testing, preventing vibrations caused by the position switching mechanism 5 during the position switching process. This, in turn, avoids damage to the internal wiring connections of the relay under high temperature and vibration. The problem of relay detachment is addressed, thus ensuring the accuracy of relay test results and reducing relay malfunctions caused by the external environment during testing. This avoids secondary damage to the relay after testing. Cooling station 9 is used to apply external cold air directly to the relay when the conveyor chain 3 stops at this position, effectively cooling the relay. After cooling, the relay is transferred to cooling testing station 10 for testing to determine if there is any continuity problem after cooling. If not, the relay is transferred to unloading station 11, where an external robotic arm transfers the relay to the unloading equipment. When transferring the relays, that is, transferring the relays from the support frame 514 to the testing station, the adjusting motor 51 first drives the adjusting turntable 513, so that the adjusting turntable 513 can move the first mounting base 52 or the second mounting base 512 to the bottom of the support frame 514. Then, the transfer cylinder 510 controls the height of the transfer support base 511, thereby controlling the height of the support column 57, so that the support column 57 can act on the mounting groove 517 to lift the mounting support plate 518, thereby separating the testing support base 519 and the side base 520, which facilitates the movement of the testing support base 519 carrying a large number of relays, and facilitates the batch testing of the relays again. When testing a relay, the height of the testing support base 519 is controlled by the transfer cylinder 510, so that the testing support base 519 is located between the testing plate 528 and the testing top plate 524. Then, the height of the transfer cylinder 510 is controlled so that the relay pins fall onto the testing plate 528. Then, the longitudinal pressure applied by the testing top plate 524 ensures that the relay can stably contact the on / off contact platform 527. The circuit is activated to control the on / off contact platform 527 to test the relay, and the test results are sent to the system platform for feedback. The temperature of the relay is monitored in real time using a temperature sensor 530. At the same time, the cooling jet outlet 532 connected to the cold air duct is used to initially cool the relay after testing. In this application, testing the relay after cooling can reduce the possibility of circuit breakage caused by the relay operating in a high-temperature environment and generating vibration. At the same time, since the height of the support platform 59 is adjustable, that is, the compression height of the support spring 55 is adjustable, it is easy to press down the relay using the detection top plate 524, so that the relay can stably act on the on / off contact platform 527, ensuring stable detection of the relay.
