Description

Technical Field

[0001] The utility model relates to the field of battery production, in particular to a battery cover pole column thrust test fixture and equipment. Background Art

[0002] In modern society, batteries are an important source of energy and are widely used in various fields, such as: consumer electronics, transportation, aerospace, communication, etc. To ensure the safety and performance reliability of batteries during use and extend their lifespan, a battery cover is generally provided on the battery to protect the battery module from external impacts that may damage its internal structure or cause corrosion of the internal electrochemical materials due to external environmental influences.

[0003] Existing battery covers generally have pole columns for connecting the inner and outer ends of the battery. The pole column is an important component of the battery, and its quality directly affects the safe use of the battery. Therefore, during the production process of the battery, it is often necessary to test the strength and stability of the pole column to ensure that the pole column will not be damaged or de-soldered due to external forces under various stress conditions, thereby avoiding safety risks such as internal short circuits and liquid leakage in the battery.

[0004] In current battery production, after the production of the battery pole column is completed, a thrust test is generally carried out on the pole column. By applying external thrust in three directions of X, Y, and Z (i.e., the left-right direction, the front-back direction, and the up-down direction), the ultimate thrust that the pole column can withstand in each of the three directions is detected (judged by whether the pole column is damaged or de-soldered on the battery cover), which is used as the basis for judging the strength and stability of the pole column. For the thrust test, there are various methods in the industry at present, and the types of thrust test equipment used are also diverse. Generally speaking, it is necessary to first clamp and fix the battery cover with a test fixture, and then carry out a thrust test on the pole column on the battery cover through the thrust test equipment. The above test fixture is generally called a battery cover pole column thrust test fixture in the industry.

[0005] In the prior art, the universality of the battery cover pole column thrust test fixture is poor and cannot meet the thrust test requirements in different directions. Different test fixtures are often required for thrust tests in different directions. On the one hand, using multiple test fixtures will increase the battery test cost. On the other hand, using different test fixtures makes the test operation more complex, increases the test difficulty, and thus affects the test efficiency. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] The present utility model provides a battery cover pole thrust test fixture, which can be used for the thrust test of the pole 102 on the battery cover 101. As Figure 1 shown, the test product of this embodiment is a common square battery cover 101 in the industry. Positive and negative poles 102 are provided on the battery cover 101. In order to test the strength and stability of the pole 102, it is necessary to perform a thrust test on the pole 102. By applying external thrust in three directions of X, Y, and Z (as Figure 1 shown, corresponding to the left-right direction, the front-back direction, and the up-down direction respectively), the limit thrust that the pole can withstand in each of the three directions is detected (judged by whether the pole is damaged or de-soldered on the battery cover), as the basis for determining the strength and stability of the pole. It should be noted that taking the square battery cover 101 as the test product in this embodiment is only one of the implementation manners, and does not limit the implementation scope of the present utility model in this way. Any relevant changes and adjustments of other product structures based on this embodiment belong to the protection scope of the present utility model.

[0035] As Figure 2 , Figure 3 shown, it is a schematic structural diagram of the battery cover pole thrust test fixture. The battery cover pole thrust test fixture includes a fixed base 1 and a pressing member 2; as Figure 4 , Figure 5As shown in the figure, a first groove 11 that is adapted to the shape and size of the battery cover plate 101 and can accommodate the battery cover plate 101 is formed above the fixed base 1. A through hole 12 is formed at the bottom of the first groove 11 of the fixed base 1 at a position corresponding to the lower part of the pole column 102. The through hole 12 is arranged vertically downward, and the diameter of the through hole 12 is greater than or equal to the diameter of the pole column 102. The pressing member 2 is arranged above the first groove 11 and is used to press the battery cover plate 101 tightly in the first groove 11. More preferably, a gap of 0.1-0.5 mm is provided around the first groove 11, which is convenient for taking and placing the battery cover plate 101.

[0036] During the test, first place the battery cover plate 101 in the first groove 11 of the fixed base 1, and then use the pressing member 2 to press the surface of the battery cover plate 101 so that the battery cover plate 101 is fixed in the first groove 11. Then, fix the fixed base 1, and apply thrusts in three directions of X, Y, and Z to the pole column 102 through a thrust test device to test the strength and stability of the pole column 102. Specifically, when the thrusts applied in the X and Y directions exceed the maximum force value of the pole column 102 in these directions, the pole column 102 will be damaged or de-soldered on the battery cover plate. When the thrust applied in the Z direction exceeds the maximum force value of the pole column 102 in this direction, the pole column 102 will be damaged or de-soldered on the battery cover plate and fall into the through hole 12.

[0037] For the battery cover plate pole column thrust test fixture with the above structure, the battery cover plate 101 can be fixed and pressed tightly through the cooperation of the fixed base 1 and the pressing member 2. Just using one test fixture can simultaneously meet the detection requirements for the strength and stability of the pole column 102 in three different directions of X, Y, and Z. Compared with the prior art, it saves the test cost, simplifies the test operation, reduces the test difficulty, and thus improves the test efficiency.

[0038] In some embodiments, as Figure 6 shown, the battery cover plate pole column thrust test fixture further includes a pole column cover plate 3. The pole column cover plate 3 is polygonal. Preferably, it can be square, regular hexagon, or regular octagon, etc. A second groove 31 that is adapted to the shape and size of the pole column 102 is formed at the bottom of the pole column cover plate 3, so that the pole column cover plate 3 can be inlaid and sleeved on the pole column 102.

[0039] For the battery cover pole thrust test fixture with the above structure, before performing the thrust tests in the X and Y directions, first insert and sleeve the pole cover plate 3 onto the pole 102, and then apply thrusts in the X and Y directions to the pole cover plate 3 through a thrust test device. The thrusts are transmitted through the pole cover plate 3 to the pole 102 embedded in the pole cover plate 3, and thus the thrust tests of the pole 102 in the X and Y directions can be realized. The setting of the pole cover plate 3 increases the contact area when the thrust test device applies thrusts, and can avoid the situation of slipping when directly performing the thrust test on the pole 102, thereby preventing the thrust test results from being invalidated.

[0040] In some embodiments, the pole cover plate 3 is square. The square pole cover plate 3 has a better force-receiving effect during the thrust test, and there are force-receiving surfaces in both the X and Y directions, so the thrust tests in the X and Y directions can be directly carried out without adjustment.

[0041] In some embodiments, the pressing component 2 is a square pressing block arranged around the first groove 11 and pressing the battery cover plate 101, and the number of the square pressing blocks is at least one; when the number of the square pressing blocks is one, preferably, the effect is better when the square pressing block presses the battery cover plate 101; of course, as a better solution, the number of the square pressing blocks is two. Compared with one square pressing block, the pressing effect is better, and compared with multiple square pressing blocks, the cost is lower. It is a better solution that takes into account both the pressing effect and the cost. In this embodiment, the number of the square pressing blocks is two, and six screw holes are arranged around the first groove 11. The specific distribution is one on each of the left and right sides of the first groove 11 and two on each of the front and rear sides; the square pressing blocks are detachably installed in the screw holes. During the test, when performing the thrust test in the X direction, the square pressing blocks are installed in the front and rear screw holes to press the battery cover plate 101; when performing the thrust tests in the Y and Z directions, the square pressing blocks are installed in the left and right screw holes to press the battery cover plate 101. Of course, the square pressing blocks can also be installed at other positions of the fixed base 1 as long as the battery cover plate 101 can be stably pressed.

[0042] For the battery cover pole thrust test fixture with the above structure, the battery cover plate 101 is pressed by the square pressing blocks, and the pressing effect is good and the operation is flexible.

[0043] The present invention also provides a battery cover pole thrust test device, such as Figures 7 - 12As shown, the battery cover pole thrust testing device includes a thrust component 4, a first clamping component 5, a second clamping component 6, and the above-mentioned battery cover pole thrust testing fixture. The first clamping component 5 is used to fix the fixed base 1. The fixing method can be achieved by screw assembly or clamping with a chuck, as long as it can ensure that the fixed base 1 remains stationary during testing. The second clamping component 6 is used to fix the thrust component 4. The fixing method can also be achieved by screw assembly or clamping with a chuck, as long as it can ensure that the thrust component 4 remains stationary in the second clamping component 6. The thrust component 4 is used to apply a thrust to the pole 102.

[0044] During testing, first place the battery cover 101 in the first groove 11 of the fixed base 1, and then use the pressing component 2 to press the surface of the battery cover 101 so that the battery cover 101 remains stationary in the first groove 11. Then, fix the fixed base 1 through the first clamping component 5, and apply thrusts in the X, Y, and Z directions to the pole 102 through the thrust component 4 to test the strength and stability of the pole 102. Specifically, when the thrusts applied in the X and Y directions exceed the maximum force-bearing value of the pole 102 in that direction, the pole 102 will be damaged or become unsoldered on the battery cover. When the thrust applied in the Z direction exceeds the maximum force-bearing value of the pole 102 in that direction, the pole 102 will be damaged or become unsoldered on the battery cover and fall into the through hole 12.

[0045] For the battery cover pole thrust testing device with the above structure, the battery cover 101 can be fixed and pressed through the cooperation of the fixed base 1, the pressing component 2, and the first clamping component 5. The thrust can be applied to the pole 102 through the cooperation of the thrust component 4 and the second clamping component 6, which can simultaneously meet the detection requirements for the strength and stability of the pole 102 in three different directions of X, Y, and Z. Compared with the prior art, it saves the testing cost, simplifies the testing operation, reduces the testing difficulty, and thus improves the testing efficiency.

[0046] In some embodiments, the thrust component 4 includes a first thrust rod 41 and a second thrust rod 42. The first thrust rod 41 is a flat square thrust block, and the second thrust rod 42 is a cylindrical thrust rod, and the diameter of the second thrust rod 42 is smaller than the diameter of the pole 102.

[0047] For the battery cover pole thrust testing device with the above structure, such as Figure 1As shown, since the terminal post 102 is generally cylindrical and slightly protrudes from the surface of the battery cover plate 101, in order to achieve better thrust effects in three different directions of X, Y, and Z during the thrust test, a first thrust rod 41 and a second thrust rod 42 are respectively provided for applying thrust. The first thrust rod 41 is a flat square thrust block for applying thrust to the terminal post 102 in the X and Y directions. The second thrust rod 42 is a cylindrical thrust rod with a diameter smaller than that of the terminal post 102 for applying thrust to the terminal post 102 in the Z direction. The above settings of the first thrust rod 41 and the second thrust rod 42 can result in a larger acting area of the thrust and better thrust effects during the thrust test.

[0048] In some embodiments, the battery cover plate terminal post thrust test device further includes a first clamping auxiliary component 7. The first clamping component 5 includes two clamping plates that are oppositely arranged and can approach or separate from each other. The first clamping auxiliary component 7 includes a clamping end and a fixed end, and the fixed end is detachably installed on the fixed base 1, and the clamping end can be clamped and fixed between the two clamping plates of the first clamping component 5.

[0049] For the battery cover plate terminal post thrust test device with the above structure, when the fixed base 1 exceeds the clamping range of the first clamping component 5 and the first clamping component 5 cannot directly clamp and fix the fixed base 1, by installing the first clamping auxiliary component 7 on the fixed base 1 and then clamping and fixing the first clamping auxiliary component 7 in the first clamping component 5, the fixation of the fixed base 1 can be achieved, thus being applicable to the case where the size of the fixed base 1 is relatively large, and further improving the versatility of the battery cover plate terminal post thrust test device.

[0050] In some embodiments, the first clamping auxiliary component 7 includes a first clamping strip 71 and a second clamping strip 72; the fixed end of the first clamping strip 71 is detachably mounted on the side or top of the fixed base 1, such that the clamping end of the first clamping strip 71 is located on the side of the fixed base 1, and the thickness of the clamping end of the first clamping strip 71 is less than the height of the fixed base 1; in this embodiment, the fixed end of the first clamping strip 71 is detachably mounted on the top of the fixed base 1 and partially protrudes out of the side of the fixed base 1, such that the clamping end of the first clamping strip 71 is located on the side of the fixed base 1, so that the fixed base 1 can be fixed on the side when performing the thrust test in the X and Y directions. Of course, it is also possible to directly and detachably mount the fixed end of the first clamping strip 71 on the side of the fixed base 1 to make the clamping end of the first clamping strip 71 located on the side of the fixed base 1; the fixed end of the second clamping strip 72 is detachably mounted on the bottom of the fixed base 1, such that the clamping end of the second clamping strip 72 is located on the bottom of the fixed base 1, and the thickness of the clamping end of the second clamping strip 72 is less than the length and / or width of the fixed base 1.

[0051] For the battery cover pole column thrust test device with the above structure, in order to better realize the fixing effect of the first clamping component 5 on the fixed base 1, for the thrust test in the X and Y directions, a first clamping strip 71 is provided, the clamping end of the first clamping strip 71 is located on the side of the fixed base 1, and the thickness of the clamping end of the first clamping strip 71 is less than the height of the fixed base 1; for the thrust test in the Z direction, a second clamping strip 72 is provided, the clamping end of the second clamping strip 72 is located on the bottom of the fixed base 1, and the thickness of the clamping end of the second clamping strip 72 is less than the length and / or width of the fixed base 1, which can make the clamping of the first clamping component 5 on the fixed base 1 more stable and improve the clamping and fixing effect of the first clamping component 5.

[0052] Specifically, as Figure 7 , Figure 8 shown in the schematic diagram of the thrust test in the X direction, taking the thrust test of the pole column 102 on the right side of the battery cover 101 as an example, the first clamping strip 71 is installed on the left side of the top of the fixed base 1 and partially protrudes out of the left side of the fixed base 1, such that the clamping end of the first clamping strip 71 is located on the left side of the fixed base 1, and then the clamping end of the first clamping strip 71 is clamped by the first clamping component 5 to realize the fixation of the fixed base 1, and then a leftward thrust is applied to the pole column 102 on the right side by the thrust component 4; for the thrust test of the pole column 102 on the left side of the battery cover 101, the positions of the first clamping strip 71, the first clamping component 5 and the thrust component 4 are swapped.

[0053] As Figure 9 , Figure 10 shown in the figure is a schematic diagram of the Y-direction thrust test. Taking the thrust test of the pole 102 on the left side of the battery cover plate 101 as an example, the first clamping strip 71 is installed in front of the top of the fixed base 1, and part of it protrudes from the front of the fixed base 1, so that the clamping end of the first clamping strip 71 is located in front of the fixed base 1. Then, the clamping end of the first clamping strip 71 is clamped by the first clamping component 5 to fix the fixed base 1. Then, a forward thrust is applied to the pole 102 by the thrust component 4 at the back. Of course, the positions of the first clamping strip 71, the first clamping component 5, and the thrust component 4 can also be exchanged to apply a backward thrust to achieve the Y-direction thrust test. When performing the thrust test on the pole 102 on the right side of the battery cover plate 101, refer to this and adjust the positions of the first clamping strip 71, the first clamping component 5, and the thrust component 4 to the corresponding positions of the pole 102 on the right side.

[0054] As Figure 11 , Figure 12 shown in the figure is a schematic diagram of the Z-direction thrust test. Taking the thrust test of the pole 102 on the right side of the battery cover plate 101 as an example, the first clamping strip 71 is installed at the bottom of the fixed base 1, so that the clamping end of the first clamping strip 71 is located at the bottom of the fixed base 1. Then, the clamping end of the first clamping strip 71 is clamped by the first clamping component 5 to fix the fixed base 1. Then, a downward thrust is applied to the pole 102 by the thrust component 4 at the top. When performing the thrust test on the pole 102 on the left side of the battery cover plate 101, refer to this and adjust the positions of the first clamping strip 71, the first clamping component 5, and the thrust component 4 to the corresponding positions of the pole 102 on the left side.

[0055] In some embodiments, the battery cover plate pole thrust test device further includes a second clamping auxiliary component 8; the second clamping component 6 includes two clamping plates arranged oppositely and capable of approaching or separating from each other; the second clamping auxiliary component 8 can be clamped and fixed between the two clamping plates of the second clamping component 6; the second clamping auxiliary component 8 is arranged at one end of the thrust component 4 away from the fixed base 1 and can clamp and fix the thrust component 4.

[0056] For the battery cover plate pole thrust test device with the above structure, the second clamping component 6 clamps and fixes the thrust component 4 through the second clamping auxiliary component 8 as an intermediate component, so that the second clamping component 6 can clamp and fix the thrust components 4 with different shapes and specifications, further improving the versatility of the battery cover plate pole thrust test device.

[0057] In some embodiments, the second clamping auxiliary component 8 is composed of a left clamping plate 81 and a right clamping plate 82, and a clamping groove for clamping and fixing the thrust component 4 is arranged between the left clamping plate 81 and the right clamping plate 82, so that stable clamping of the thrust component 4 can be realized.

[0058] The above embodiments are only preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Any equivalent changes made according to the shape, structure and principle of the present invention shall be covered by the protection scope of the present invention.
