However, existing testing fixtures are not convenient for clamping different battery models, causing inconvenience in testing. Utility Model Content

[0003] Therefore, it is necessary to provide a testing fixture that can clamp batteries of different models to address the above problems.

[0004] On the one hand, this application provides a testing fixture, the testing fixture comprising:

[0008] When the clamping bodies of the two clamping assemblies move away from each other, and cause the first clamping member and the second clamping member to move away from each other, the clamping bodies of the two clamping assemblies, as well as the first clamping member and the second clamping member, jointly release the battery located at the detection station.

[0019] In some embodiments, the detection assembly further includes a lifting drive component, which is mounted on the mounting frame and connected to the mounting platform via a transmission connection. The lifting drive component is used to drive the mounting platform to move the detection contact reciprocally along the third direction.

[0020] In some embodiments, the first clamping member and the second clamping member are rotatably mounted on the clamping body about a third direction, which intersects both the first direction and the second direction.

[0043] In recent years, the new energy industry has received increasing attention, and batteries, as a crucial component of this industry, occupy a significant market share. During battery use, testing fixtures are needed to clamp the batteries and test their health (e.g., insulation withstand voltage performance). However, existing testing fixtures are not convenient for clamping different battery models, causing inconvenience in testing.

[0044] Please see Figure 1 , Figure 1This is a schematic diagram of the overall structure of the testing fixture 100 in one embodiment of this application. To alleviate the above-mentioned problems, this application provides a testing fixture 100, which includes a mounting frame 10 and two clamping assemblies 20. The mounting frame 10 has a testing station 112, and the two clamping assemblies 20 are disposed on the mounting frame 10 and are arranged at intervals along a first direction X on opposite sides of the testing station 112. Each of the two clamping assemblies 20 includes a clamping body 21; at least one of the two clamping assemblies 20 includes a first clamping member 22 and a second clamping member 23. For example, both clamping assemblies 20 include a first clamping member 22 and a second clamping member 23. The first clamping member 22 and the second clamping member 23 are mounted on the side of the clamping body 21 facing the testing station 112, and the first clamping member 22 and the second clamping member 23 are arranged along a second direction Y intersecting the first direction X on opposite sides of the testing station 112. When the clamping bodies 21 of the two clamping assemblies 20 move closer together, causing the first clamping member 22 and the second clamping member 23 to move closer together, the clamping bodies 21 of the two clamping assemblies 20, as well as the first clamping member 22 and the second clamping member 23, jointly clamp the battery located at the inspection station 112. When the clamping bodies 21 of the two clamping assemblies 20 move away from each other, causing the first clamping member 22 and the second clamping member 23 to move away from each other, the clamping bodies 21 of the two clamping assemblies 20, as well as the first clamping member 22 and the second clamping member 23, jointly release the battery located at the inspection station 112.

[0045] Specifically, the mounting frame 10 includes a top plate 12, a bottom plate 11, and a plurality of support columns 13. The top plate 12 and the bottom plate 11 are spaced apart along a third direction Z, and the plurality of support columns 13 are supported between the top plate 12 and the bottom plate 11. The bottom plate 11 has a bearing surface 111 facing the top plate 12. The bearing surface 111 is used to support the clamping assembly 20, and the bearing surface 111 has a testing station 112 for placing batteries.

[0046] Among them, any two of the first direction X, the second direction Y, and the third direction Z intersect. Figure 1 Taking the state of the detection fixture 100 as an example, the first direction X is the left and right horizontal direction, the second direction Y is the front and back horizontal direction, and the third direction Z is the vertical direction.

[0047] Furthermore, the first direction X can be one of the length, width, and thickness directions of the battery; the second direction Y can be another of the length, width, and thickness directions; and the third direction Z can be a third of the length, width, and thickness directions. For example, the first direction X can be the length direction of the battery, the second direction Y can be the width direction of the battery, and the third direction Z can be the thickness direction of the battery.

[0048] Taking two clamping components 20, each including a first clamping member 22 and a second clamping member 23, as an example, during actual operation, when the clamping bodies 21 of the two clamping components 20 move closer to each other, causing the first clamping member 22 and the second clamping member 23 to move closer to each other, the clamping bodies 21 of the two clamping components 20 clamp the battery along the first direction X, and the first clamping member 22 and the second clamping member 23 of the same clamping component 20 clamp the battery along the second direction Y. When the clamping bodies 21 of the two clamping components 20 move away from each other, causing the first clamping member 22 and the second clamping member 23 to move away from each other, the clamping bodies 21 of the two clamping components 20 release the battery along the first direction X, and the first clamping member 22 and the second clamping member 23 of the same clamping component 20 release the battery along the second direction Y.

[0049] In this application, by designing the clamping bodies 21 of the two clamping components 20 to move closer to each other along the first direction X, and the first clamping member 22 and the second clamping member 23 in the clamping components 20 to move closer to each other along the second direction Y, the degree of proximity of the clamping bodies 21 of the two clamping components 20 and the degree of proximity of the first clamping member 22 and the second clamping member 23 in the same clamping component 20 can be adjusted according to different battery models, so that different models of batteries can be clamped, providing convenience for the testing of different battery models. After the testing is completed, the clamping bodies 21 of the two clamping components 20, as well as the first clamping member 22 and the second clamping member 23 in each clamping component 20, release the battery to facilitate the removal, placement, and replacement of the battery.

[0050] Furthermore, when the clamping bodies 21 of the two clamping components 20 approach each other, they cause the first clamping member 22 and the second clamping member 23 to approach each other. When the clamping bodies 21 of the two clamping components 20 move away from each other, they cause the first clamping member 22 and the second clamping member 23 to move away from each other. This method can eliminate the need for a drive structure to drive the first clamping member 22 and the second clamping member 23 to move, simplifying the structure of the inspection fixture 100 and reducing manufacturing costs.

[0051] Please refer to it again. Figure 1 And see also Figure 4 , Figure 4 This application presents schematic diagrams illustrating the structure of the clamping assembly 20 and the traction assembly 30 cooperating in the testing fixture 100 according to some embodiments. In some embodiments, both clamping assemblies 20 include a support seat 24 and an elastic element 25. The support seat 24 and the elastic element 25 are both located on the side of the clamping body 21 facing away from the testing station 112, and the elastic element 25 is connected between the support seat 24 and the clamping body 21. The testing fixture 100 also includes a traction assembly 30, which corresponds one-to-one with the clamping assembly 20. The traction assembly 30 and the corresponding elastic element 25 cooperate to drive the corresponding clamping body 21 to reciprocate along the first direction X.

[0052] Specifically, the elastic element 25 can be a compression spring, a sheet spring, or other structure with an elastic element 25. There can be one or at least two elastic elements 25 in the same clamping assembly 20. For example, there are at least two elastic elements 25 in the same clamping assembly 20, spaced apart along the second direction Y.

[0053] In actual operation, when the elastic force of the elastic element 25 is greater than the traction force of the corresponding traction component 30, the elastic force provided by the elastic element 25 drives the clamping body 21 to move towards the detection station 112 in the first direction, so that the battery can be clamped in the detection station 112. When the elastic force of the elastic element 25 is less than the traction force of the corresponding traction component 30, the traction force of the traction component 30 overcomes the elastic force and pulls the clamping body 21 to move away from the detection station 112 in the first direction, and the battery is released to facilitate the removal and placement of the battery. It is worth mentioning that during the process of the clamping body 21 moving away from the detection station 112, the elastic element 25 is further compressed, and the elastic force gradually increases.

[0054] The elastic element 25 drives the clamping body 21 to move toward the inspection station 112 in a simple and reliable manner, which simplifies the structure of the inspection fixture 100.

[0055] In some embodiments, the first clamping member 22 and the second clamping member 23 are both rotatably mounted on the clamping body 21 in the Z direction around a third party.

[0056] In order to drive the first clamping member 22 and the second clamping member 23 to rotate about a third direction Z, at least one of the two clamping assemblies 20 includes a first pull rope 28 and a second pull rope 29. The first pull rope 28 passes through the clamping body 21, and its two ends are respectively connected to the support seat 24 and the first clamping member 22; the second pull rope 29 passes through the clamping body 21, and its two ends are respectively connected to the support seat 24 and the second clamping member 23. The first clamping member 22 and the second clamping member 23 rotate about a third direction Z under the action of the first pull rope 28 and the second pull rope 29, respectively.

[0057] Specifically, both the first pull rope 28 and the second pull rope 29 can be elastic ropes.

[0058] In actual operation, when the clamping bodies 21 of the two clamping components 20 approach each other, the clamping bodies 21 will also drive the first clamping member 22 and the second clamping member 23 away from the support seat 24, causing the first clamping member 22 and the second clamping member 23 to rotate under the pull of the first pull rope 28 and the second pull rope 29 respectively, so that the first clamping member 22 and the second clamping member 23 can approach each other along the second direction Y and clamp the battery. During this process, the first pull rope 28 and the second pull rope 29 are stretched, reducing the moving speed of the clamping bodies 21.

[0059] When the clamping bodies 21 of the two clamping components 20 move away from each other, the clamping bodies 21 drive the first clamping member 22 and the second clamping member 23 to approach the support seat 24, so that the first clamping member 22 and the second clamping member 23 rotate under the pull of the first pull rope 28 and the second pull rope 29 respectively, so that the first clamping member 22 and the second clamping member 23 can move away from each other along the second direction Y and release the battery.

[0060] The first clamping member 22 and the second clamping member 23 are driven to rotate by the first pull rope 28 and the second pull rope 29, so that the first clamping member 22 and the second clamping member 23 can move closer to each other or further away from each other. This method is simple and easy to operate.

[0061] In some embodiments, the clamping body 21 is provided with a first hinge seat 211 and a second hinge seat 212. The first clamping member 22 includes a first hinge joint 221, a first connecting rod 222, and a first clamping head 223. The first hinge joint 221 is hinged to the first hinge seat 211, and the first connecting rod 222 connects the first hinge joint 221 and the first clamping head 223. The second clamping member 23 includes a second hinge joint 231, a second connecting rod 232, and a second clamping head 233. The first hinge joint 221 is hinged to the first hinge seat 211, the second hinge joint 231 is hinged to the second hinge seat 212, and the second connecting rod 232 connects the second hinge joint 231 and the second clamping head 233. A first pull rope 28 is connected to the first connecting rod 222, and a second pull rope 29 is connected to the second connecting rod 232. Under the action of the first pull rope 28, the first hinge joint 221, the first connecting rod 222, and the first clamping head 223 rotate synchronously relative to the first hinge seat 211, and the second hinge joint 231, the second connecting rod 232, and the second clamping head 233 rotate synchronously relative to the second hinge seat 212. By setting the first hinge joint 221, the second hinge joint 231, the first hinge seat 211, and the second hinge seat 212, the normal installation and rotation of the first clamping member 22 and the second clamping member 23 can be guaranteed.

[0062] In some embodiments, the end of the first clamping member 22 away from the clamping body 21 and the end of the second clamping member 23 away from the clamping body 21 are both provided with a buffer block or a roller that rolls around the third direction Z.

[0063] The buffer block can be a rubber block, a silicone block, etc.

[0064] During the compression of the buffer block or the rolling of the roller, the squeezing effect of the first clamping member 22 and the second clamping member 23 on the battery can be reduced to avoid battery deformation and improve the safety of the test.

[0065] In some embodiments, a buffer block is also provided on the surface of the clamping body 21 facing the detection station 112 to prevent the clamping body 21 from squeezing the battery and causing the battery to deform.

[0066] Please see Figure 1 And see also Figures 2 to 4 , Figure 2 This is a schematic diagram of the detection fixture 100 without a clamping component 20 in one embodiment of this application. Figure 2 In the middle, the traction assembly 30 connected to the removed clamping assembly 20 is an explosive structure. After the explosion, the mounting base 32 and magnetic component 33 in the traction assembly 30 extend out of the guide channel 341. Figure 3 for Figure 2 An enlarged schematic diagram of a local structure A in the detection fixture 100 shown.

[0067] In some embodiments, the clamping assembly 20 further includes an adsorption member 26, which is installed on the side of the clamping body 21 facing away from the detection station 112; the traction assembly 30 includes a traction rope 31, a mounting base 32, and a magnetic member 33; in the corresponding traction assembly 30 and clamping assembly 20, the mounting base 32 and the magnetic member 33 are both disposed on the side of the clamping body 21 facing away from the clamping body 21, and the mounting base 32 is connected between the traction rope 31 and the magnetic member 33. The magnetic member 33 and the adsorption member 26 are attracted to each other, and the magnetic attraction between the magnetic member 33 and the adsorption member 26 forms a traction force.

[0068] The mounting base 32 can fix the traction rope 31 and the magnetic component 33, and drive the magnetic component 33 to move.

[0069] Among them, the magnetic component 33 is a strong magnet, and the adsorption component 26 can be a magnet or a metal structure.

[0070] In the corresponding traction assembly 30 and clamping assembly 20, the distance between the magnetic component 33 and the adsorption component 26 determines the magnitude of the magnetic attraction between them. When the distance between the magnetic component 33 and the adsorption component 26 is small or even zero, and the magnetic attraction between them is greater than the elastic force of the elastic component 25, the clamping body 21 moves away from the detection station 112 under the action of the magnetic attraction and the magnetic attraction between the magnetic component 33 and the adsorption component 26, and the battery is released. When the distance between the magnetic component 33 and the adsorption component 26 is large, and the magnetic attraction between them is less than the elastic force of the elastic component 25, the clamping body 21 moves towards the detection station 112 under the action of the elastic force, and the battery is clamped.

[0071] The method of using the magnetic attraction between the magnetic component 33 and the adsorption component 26 to form a traction force, and driving the clamping body 21 to move away from the detection station 112 when the magnetic attraction force is greater than that of the elastic component 25, is simple and easy to operate, can be reused, and has a long service life. At the same time, during the process of the elastic force of the elastic component 25 pushing the clamping body 21 to move and clamp the battery, the magnetic attraction force will also reduce the moving speed of the clamping body 21 to prevent the clamping body 21 from rebounding too quickly and hitting the battery.

[0072] Specifically, in this embodiment, the clamping assembly 20 includes two elastic members 25, which are spaced apart along the second direction Y. The adsorption member 26 is located between the two elastic members 25. This design can make the force on the clamping body 21 more balanced, which is beneficial to improving the stability of the movement of the clamping body 21.

[0073] In some embodiments, the traction assembly 30 further includes a guide 34 located on the side of the clamping body 21 facing away from the detection station 112, and the guide 34 has a guide channel 341 extending along the first direction X. The mounting base 32 and the suction member 26 are both disposed within the guide channel 341, and the mounting base 32 and the suction member 26 are slidably engaged with the guide channel 341, so that the mounting base 32 and the suction member 26 slide under the guidance of the guide channel 341, and the sliding is smoother.

[0074] Specifically, the guide channel is adapted to the shape of the mounting base 32 and the adsorption component 26 so that the guide channel can guide the movement of the mounting base 32, the magnetic component 33 and the adsorption component 26, thereby improving the stability of the movement of the mounting base 32, the magnetic component 33 and the adsorption component 26 and preventing the mounting base 32, the magnetic component 33 and the adsorption component 26 from being misaligned or tilted under the action of external force.

[0075] In some embodiments, the clamping assembly 20 further includes a plug-in post 27, which is connected between the adsorption member 26 and the clamping body 21, and is slidably inserted into the guide channel 341. The plug-in post 27, the adsorption member 26, and the guide channel 341 work together to guide the sliding of the clamping body 21, preventing the clamping body 21 from causing the first clamping member 22 and the second clamping member 23 to shift during movement.

[0076] In some embodiments, the testing fixture 100 further includes a testing component 40, which includes a testing instrument, a mounting platform 41, and a testing contact 42. The testing contact 42 is mounted on the mounting platform 41 and is used to test the battery clamped at the testing station 112. The testing contact 42 is electrically connected to the testing instrument. A traction rope 31 is wound around the mounting frame 10, and one end of the traction rope 31 away from the mounting base 32 is connected to the mounting platform 41. The traction rope 31 is used to pull the mounting base 32 away from the magnetic component 33 away from the adsorption component 26 when the mounting platform 41 and the testing contact 42 move in the third direction Z toward the testing station 112.

[0077] Specifically, the detector is electrically connected to the detection contact 42. The detector receives the information fed back by the detection contact 42 and judges the health status of the battery based on the information.

[0078] The detection contact 42 can be one or more, and the detection contact 42 is disposed on the surface of the mounting platform 41 facing the detection station 112.

[0079] Specifically, the traction rope 31 can be a flexible rope. The traction rope 31 is wound around the mounting frame 10, and one end of the traction rope 31 is connected to the mounting base 32, while the other end passes through the top plate 12 and is connected to the mounting platform 41.

[0080] In actual operation, the mounting platform 41 lowers the detection contact 42 and gradually approaches the battery located at the detection station 112. The traction rope 31 is pulled by the mounting platform 41, pulling the magnetic component 33 away from the adsorption component 26, thereby increasing the distance between the magnetic component 33 and the adsorption component 26 and reducing the magnetic attraction between them. When the magnetic attraction between the magnetic component 33 and the adsorption component 26 is less than the elastic force of the elastic component 25, the clamping body 21 moves towards the detection station 112 under the action of the elastic force of the elastic component 25, so that the battery can be clamped by the clamping body 21 of the two clamping assemblies 20. At the same time, the first clamping component 22 and the second clamping component 23 move closer to each other under the action of the first pull rope 28 and the second pull rope 29, respectively, so that the battery can be clamped by the first clamping component 22 and the second clamping component 23 of the same clamping assembly 20. When the battery is clamped, the detection contact 42 moves to the lowest position and begins to perform detection on the battery.

[0081] After the test, the mounting platform 41 drives the test contact 42 to rise and gradually move away from the battery located at the test station 112. The traction rope 31 is no longer pulled by the mounting platform 41. At this time, the magnetic component 33 gradually approaches the adsorption component 26, and the magnetic attraction between the magnetic component 33 and the adsorption component 26 gradually increases. When the magnetic attraction between the magnetic component 33 and the adsorption component 26 increases to a level greater than the elastic force of the elastic component 25, the adsorption component 26 overcomes the elastic force of the elastic component 25 and drives the clamping body 21 to move towards the magnetic component 33, that is, the clamping body 21 moves away from the test station 112. At the same time, the first clamping component 22 and the second clamping component 23 move away from each other to release the clamping of the battery, making it convenient to pick up, put down and replace the battery.

[0082] By setting the detection component 40 and the traction component to be linked, as the detection contact 42 descends and approaches the detection station 112, the clamping bodies 21 of the two clamping components 20 can clamp the battery along the first direction X, and the first clamping member 22 and the second clamping member 23 on the clamping body 21 can clamp the battery along the second direction Y. This linkage method helps to simplify the structure of the detection fixture 100 and reduce the cost of the detection fixture 100.

[0083] In some embodiments, the detection assembly 40 further includes a lifting drive 43, which is mounted on the mounting frame 10 and connected to the mounting platform 41. The lifting drive 43 is used to drive the mounting platform 41 to move the detection contact 42 back and forth along the third direction Z.

[0084] Specifically, the lifting drive component 43 is installed on the top plate 12 to ensure the installation height of the detection contact 42.

[0085] The lifting drive unit 43 drives the mounting platform 41 to automatically raise and lower the detection contact 42, adjusting the distance between the detection contact 42 and the battery to ensure normal testing. Simultaneously, the lifting drive unit 43 performs testing only after the mounting platform 41 lowers the detection contact 42 to a certain height. During descent, the mounting platform 41 pulls the traction rope 31, causing the clamping bodies 21 of the two clamping assemblies 20, and the first clamping member 22 and the second clamping member 23 on the clamping bodies 21, to clamp the battery. The specific working process of the entire testing fixture 100 will be described in detail below.

[0086] During testing, the battery is placed at testing station 112, and then the lifting drive 43 is activated, causing the mounting platform 41 and testing contact 42 to descend. As the mounting platform 41 descends, it pulls the traction rope 31, causing the traction rope 31 to pull the magnetic component 33 away from the adsorption component 26. After the magnetic attraction force of the magnetic component 33 on the adsorption component 26 decreases to less than the elastic force of the elastic component 25, the elastic force of the elastic component 25 pushes the clamping body 21 to clamp the battery. At the same time, the magnetic attraction force also reduces the moving speed of the clamping body 21 to prevent the clamping body 21 from rebounding too quickly and impacting the battery. As the clamping body 21 moves, it also moves the first clamping component 22 and the second clamping component 23 away from the support seat 24, so that the first clamping component 22 and the second clamping component 23 clamp the battery under the pull of the first pull rope 28 and the second pull rope 29, respectively. After the battery test is completed, the lifting drive 43 drives the mounting platform 41 and the test contact 42 to rise. The magnetic component 33 will move towards the adsorption component 26 under the action of magnetic attraction. When the magnetic attraction is greater than the elastic force of the elastic component 25, the magnetic attraction pulls the clamping body 21, the first clamping component 22 and the second clamping component 23 to reset and release the clamping and positioning of the battery.

[0087] The aforementioned testing fixture 100 is designed such that the clamping bodies 21 of the two clamping components 20 can approach each other along the first direction X, and the first clamping member 22 and the second clamping member 23 in the clamping components 20 can approach each other along the second direction Y. Depending on the battery model, the degree of approach of the clamping bodies 21 of the two clamping components 20, as well as the degree of approach of the first clamping member 22 and the second clamping member 23 in the same clamping component 20, can be adjusted to clamp different models of batteries, providing convenience for the testing of different models of batteries.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
