Description

Technical Field

[0001] This application belongs to the field of battery assembly technology, specifically relating to a battery connector testing fixture. Background Technology

[0002] In the battery manufacturing industry, after each battery is assembled, the battery connector usually needs to undergo functional testing to ensure that the battery can move stably and reliably. Currently, most battery connector test fixtures are manual fixtures, which require manual insertion of the battery connector into the micro-needle test seat of the battery connector test fixture for functional testing; after the functional test is completed, the connector is manually released. However, this release method can easily cause the battery connector to be stretched and deformed, thereby reducing the battery yield. Utility Model Content

[0003] The purpose of this application is to provide a battery connector test fixture that can solve the problem that battery connectors are easily stretched and deformed during the functional testing of batteries.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a battery connector testing fixture, including an operating platform, a gripper mechanism, and a microneedle test socket. Both the gripper mechanism and the microneedle test socket are mounted on the operating platform, and the microneedle test socket is movable relative to the operating platform.

[0006] When the pressure claw mechanism is disengaged from the battery connector, the microneedle test socket descends to separate the microneedle test socket from the battery connector.

[0007] In this embodiment, the microneedle test socket can be raised and lowered relative to the operating platform. After the functional test is completed and the gripper mechanism disengages from the battery connector, the microneedle test socket is driven to descend, separating it from the battery connector. This passively disengages the battery connector from the microneedle test socket, clearing the area where the battery connector is located. The battery is then removed from the operating platform, preventing the battery connector from being stretched and deformed due to manual disengagement, thereby improving the battery yield. Therefore, this embodiment solves the problem of battery connectors being easily stretched and deformed during current battery functional testing. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The battery connector test fixture provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] like Figures 1 to 10 As shown in the figure, this application provides a battery connector testing fixture, which includes an operating platform 100, a gripper mechanism 200, and a microneedle test seat 300. Both the gripper mechanism 200 and the microneedle test seat 300 are disposed on the operating platform 100. The microneedle test seat 300 can be raised and lowered relative to the operating platform 100. Optionally, a guide rail can be provided on the operating platform 100, and the microneedle test seat 300 slides with the guide rail. At this time, the microneedle test seat 300 can be manually driven to rise and fall relative to the operating platform 100 so that the microneedle test seat 300 reciprocates between the detection position and the waiting position.

[0027] When the pressure claw mechanism 200 is disengaged from the battery connector 410, the microneedle test socket 300 descends to separate the microneedle test socket 300 from the battery connector 410.

[0028] In this embodiment, when the microneedle test socket 300 is in the detection position, the battery connector 410 is manually engaged with the microneedle test socket 300, and then the pressure claw mechanism 200 is pressed onto the battery connector 410 for functional testing. After the functional test is completed and the pressure claw mechanism 200 disengages from the battery connector 410, the microneedle test socket 300 is driven to descend, causing it to separate from the battery connector 410. This passively disengages the battery connector 410 from the microneedle test socket 300, thus clearing the area where the battery connector 410 is located. The battery 400 is then removed from the operating platform 100, preventing the battery connector 410 from being stretched and deformed due to manual disengagement, thereby improving the yield rate of the battery 400. Therefore, this embodiment can solve the problem that the battery connector 410 is easily stretched and deformed during the functional testing of the battery 400.

[0029] In an optional embodiment, the battery connector test fixture further includes a test seat drive 500. Optionally, the test seat drive 500 can be a cylinder, hydraulic cylinder, piezoelectric component, etc., and this application embodiment does not impose specific limitations on this. The test seat drive 500 is disposed on the operating platform 100, and the output shaft of the test seat drive 500 is connected to the microneedle test seat 300. The test seat drive 500 can drive the microneedle test seat 300 to rise and fall relative to the operating platform 100, which can improve the automation performance of the battery connector test fixture and save manpower. Of course, the microneedle test seat 300 can also be manually driven to rise and fall relative to the operating platform 100.

[0030] In a further optional embodiment, the position of the microneedle test socket 300 can be observed manually; alternatively, the test socket drive 500 includes a main body 510 and an output part 520 slidably connected, the output part 520 being connected to the microneedle test socket 300, and the main body 510 driving the microneedle test socket 300 to rise and fall via the output part 520. The operating platform 100 is provided with a first limiting member, and the bottom surface of the output part 520 is provided with a first limiting block 521. When the microneedle test socket 300 descends to the waiting position, the first limiting block 521 and the first limiting member limit each other. The microneedle test socket 300 is prevented from descending further to avoid excessive descent. Alternatively, the main body 510 is provided with a limiting shaft 511, one end of which extends through the output portion 520 to the side of the output portion 520 opposite to the main body 510. Optionally, the output portion 520 may have a vertically extending clearance hole, with one end of the limiting shaft 511 extending through the clearance hole to the side of the output portion 520 opposite to the main body 510. During the lifting and lowering of the output portion 520, the limiting shaft 511 moves relative to the clearance hole. A second limiting block 522 is provided on the side of the output portion 520, optionally located on the side of the output portion 520 opposite to the main body 510. When the microneedle test socket 300 rises to the detection position, the second limiting block 522 engages with the limiting shaft 511 to prevent the microneedle test socket 300 from rising further, thus preventing the microneedle test socket 300 from rising too far and facilitating the placement of the battery connector 410. This solution, by setting the first limiting block 521 and / or the second limiting block 522 in the output section 520 of the test socket drive 500, stops the movement of the microneedle test socket 300 when it rises to the detection position or falls to the waiting position, preventing the microneedle test socket 300 from rising or falling too far, thereby improving the positioning accuracy of the microneedle test socket 300.

[0031] Optionally, the position of the microneedle test socket 300 can be observed manually; or, in other optional embodiments, the battery connector test fixture further includes a position detection component and a control component. The position detection component is used to detect the position of the microneedle test socket 300, and the control component is electrically connected to the position detection component and the test socket drive component 500. The control component can control the working state of the test socket drive component 500 according to the detection information of the position detection component. Specifically, when the microneedle test socket 300 needs to descend or rise, the control component controls the test socket drive component 500 to start working; when the microneedle test socket 300 descends to the waiting position, the position detection component sends the detected first position information of the microneedle test socket 300 to the control component, and the control component controls the test socket drive component 500 to stop working according to the first position information; when the microneedle test socket 300 rises to the detection position, the position detection component sends the detected second position information of the microneedle test socket 300 to the control component, and the control component controls the test socket drive component 500 to stop working according to the second position information. This solution uses a position detection component to detect the specific position of the microneedle test socket 300, which is beneficial for precise control of the position of the microneedle test socket 300.

[0032] In a further optional embodiment, the position detection component includes a transmitter and a receiver. One of the transmitter and receiver is disposed on the microneedle test base 300, and the other is disposed on the operating platform 100. Both the transmitter and receiver are electrically connected to a control unit. The transmitter is used to emit light, and the control unit can control the working state of the test base drive unit 500 according to the received signal from the receiver. The position detection component in this solution uses the optical detection principle to detect the specific position of the microneedle test base 300, which has the characteristics of high detection accuracy and fast response, which is beneficial to improving the detection accuracy and sensitivity of the position detection component. Of course, the position detection component can also be a magnetic scale and a magnetic head. For example, the magnetic head can be disposed on the microneedle test base 300, and the magnetic scale can be disposed on the operating platform 100.

[0033] In another optional embodiment, the pressure claw mechanism 200 includes a pressure claw 210, a lifting drive 220, and a translation drive 230. Optionally, at least one of the lifting drive 220 and the translation drive 230 can be a cylinder or a hydraulic cylinder; this embodiment does not impose specific limitations on this. The translation drive 230 is disposed on the operating platform 100. The lifting drive 220 is connected to the output shaft of the translation drive 230, and the pressure claw 210 is connected to the output shaft of the lifting drive 220. The translation drive 230 can drive the lifting drive 220 and the pressure claw 210 to translate together, so that the pressure claw 210 is vertically opposite to the microneedle test seat 300. The lifting drive 220 can drive the pressure claw 210 to rise or fall, so that the pressure claw 210 moves closer to or away from the microneedle test seat 300.

[0034] Specifically, when the battery connector 410 is placed inside the microneedle test socket 300, the translation drive 230 drives the lifting drive 220 and the pressure claw 210 to translate together, so that the pressure claw 210 is vertically aligned with the microneedle test socket 300. Then, the lifting drive 220 drives the pressure claw 210 to descend, bringing it closer to the microneedle test socket 300 and pressing it against the battery connector 410, thereby fixing the battery connector 410. After the functional test is completed, the lifting drive 220 drives the pressure claw 210 to rise, moving it away from the microneedle test socket 300. Then, the translation drive 230 drives the lifting drive 220 and the pressure claw 210 to translate in the opposite direction, causing the pressure claw 210 to be vertically offset from the microneedle test socket 300. This scheme improves the movement flexibility of the pressure claw 210 by setting the lifting drive 220 and the translation drive 230 to move the microneedle test socket 300 from different directions. Of course, the translation drive 230 mentioned above can also be omitted.

[0035] In a further optional embodiment, the battery connector test fixture further includes a bracket 700, which is disposed on the operating platform 100. The bracket 700 is provided with a guide rail 710 and a limiting part 720. The pressure claw mechanism 200 further includes a first bracket 240, which is connected to the output shaft of the lifting drive 220. The pressure claw 210 is connected to the first bracket 240 so that the pressure claw 210 is connected to the lifting drive 220 through the first bracket 240. The first bracket 240 is provided with spaced sliders 241 and a second limiting part 242. The sliders 241 slide in cooperation with the guide rail 710 to improve the stability of the first bracket 240 during the lifting process. When the pressure claw 210 presses against the battery connector 410, the second limiting part 242 cooperates with the limiting part 720 to limit the pressure claw 210 to avoid excessive descent distance and damage to the battery connector 410, thereby improving the accuracy of the descent of the pressure claw 210. Of course, the positional relationship between the pressure claw 210 and the battery connector 410 can also be observed manually; or the distance the pressure claw 210 descends can be detected by a distance detection device.

[0036] In a further optional embodiment, the pressure claw mechanism 200 further includes a deformable element 250 and a second support 260. The deformable element 250 is disposed on the first support 240, and the second support 260 is slidably connected to the first support 240. The pressure claw 210 is connected to the second support 260. When the pressure claw 210 is in contact with the battery connector 410, the lifting drive member 220 can drive the deformable element 250 to descend through the first support 240 to press the second support 260, so that the pressure claw 210 presses against the battery connector 410. During this process, the second support 260 can remain stationary, and the first support 240 slides downward relative to the second support 260. At the same time, the deformable element 250 deforms. Under the action of the deformable element 250, the force on the second support 260 is transmitted to the pressure claw 210, so that the pressure claw 210 presses against the battery connector 410. This design incorporates a deformation element 250 to act as a buffer, preventing excessive driving force from causing the pressure claw 210 to exert excessive force on the battery connector 410 and damage it. Alternatively, the deformation element 250 and the second bracket 260 can be omitted.

[0037] In another optional embodiment, the pressure claw mechanism 200 further includes a third bracket 270, which is connected to the output shaft of the translation drive 230. The lifting drive 220 is disposed on the third bracket 270 so that the lifting drive 220 is connected to the translation drive 230 through the third bracket 270. The operating platform 100 is provided with a third limiting member. When the pressure claw 210 and the microneedle test seat 300 are vertically opposite each other, the third bracket 270 and the third limiting member limit each other to prevent the pressure claw 210 from moving too far in the horizontal direction and misaligning with the microneedle test seat 300, thereby improving the translation accuracy of the pressure claw 210.

[0038] In another optional embodiment, the operating platform 100 is provided with spaced-apart support platforms 120 and support platforms 110 for carrying batteries. The microneedle test socket 300 is movably mounted on the support platform 120. The battery connector test fixture also includes a prepositioning claw 600, which is rotatably mounted on the support platform 120. The microneedle test socket 300 is located between the prepositioning claw 600 and the support platform 110. The prepositioning claw 600 is provided with an clearance opening 610. The claw mechanism 200 includes a claw 210. When the battery connector 410 is located inside the microneedle test socket 300, both the prepositioning claw 600 and the claw 210 press against the battery connector 410, and a portion of the claw 210 is located within the clearance opening 610. When the battery connector 410 is placed inside the microneedle test socket 300, the pre-positioning claw 600 is first rotated to press against the edge of the battery connector 410 for pre-positioning. Then, a portion of the claw 210 extends into the clearance opening 610 of the pre-positioning claw 600 and presses against the battery connector 410 to fix it in place, thus facilitating functional testing of the battery connector 410 by the microneedle test socket 300. This solution utilizes the pre-positioning claw 600 to pre-position the battery connector 410, preventing the battery connector 410 from moving relative to the microneedle test socket 300 during the pressing process of the claw 210, thereby improving the pressing accuracy of the claw 210.

[0039] Based on the battery connector test fixture provided in this application embodiment, the specific functional testing process is as follows:

[0040] First, place the battery 400 on the support platform 110 and place the battery connector 410 inside the microneedle test holder 300. Then, rotate the pre-positioning claw 600 until it presses against the edge of the battery connector 410 for pre-positioning. Next, the translation drive 230 drives the lifting drive 220 and the claw 210 to translate together, so that the claw 210 is vertically aligned with the microneedle test holder 300. Then, the lifting drive 220 drives the claw 210 to descend, bringing the claw 210 closer to the microneedle test holder 300 and pressing it against the battery connector 410. Then, perform a functional test. After the functional test is completed, the lifting drive 220 drives the claw 210 to rise. The pressure claw 210 is moved away from the microneedle test holder 300. The translation drive 230 drives the lifting drive 220 and the pressure claw 210 to move in the opposite direction, so that the pressure claw 210 and the microneedle test holder 300 are vertically offset. Then, the test holder drive 500 drives the microneedle test holder 300 to descend to the waiting position relative to the operating platform 100, so that the microneedle test holder 300 is separated from the battery connector 410, thereby avoiding the battery connector 410. Then, the prepositioning pressure claw 600 is rotated in the opposite direction, and then the battery 400 is removed. Finally, the test holder drive 500 drives the microneedle test holder 300 to rise to the detection position relative to the operating platform 100, so as to facilitate the functional testing of the next battery connector 410.

The specific embodiments described above are merely illustrative and not restrictive.
