In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1 to 10, the battery test apparatus of the present embodiment includes a chassis 10, an insulation and voltage withstand test mechanism 30, and a thickness test mechanism 40. Wherein, the frame 10 is provided with a carrying mechanism 20, and the carrying mechanism 20 is suitable for carrying the battery 1. The insulation and voltage withstand test mechanism 30 is provided in the frame 10 and is adapted to perform an insulation and voltage withstand test on the battery 1. The thickness test mechanism 40 is disposed in the frame 10 and is adapted to perform thickness test on the battery 1. Further, the carrying mechanism 20 is adapted to place the two sets of batteries 1 on the insulation and voltage resistance testing mechanism 30 and the thickness testing mechanism 40, respectively.

By utilizing the technical scheme of the embodiment, the frame 10 of the battery testing device is simultaneously provided with the insulation and voltage resistance testing mechanism 30 and the thickness testing mechanism 40, and the carrying mechanism 20 can respectively place two groups of batteries on the insulation and voltage resistance testing mechanism 30 and the thickness testing mechanism 40, so that the insulation and voltage resistance testing and the thickness testing can be simultaneously carried out, and the production beat and the testing efficiency are improved. Therefore, the technical scheme of the embodiment solves the defect of low battery testing efficiency in the prior art.

And the battery after the test is completed flows from the discharge hole to the subsequent station.

Meanwhile, the handling mechanism 20 handles the battery 1 with the thickness tested from the thickness testing mechanism 40 to the discharge port. That is, for a certain group of cells 1, it is necessary to perform the insulation voltage test and the thickness test in order, while for the cell test device, the insulation voltage test mechanism 30 and the thickness test mechanism 40 operate simultaneously, so that the tact time is greatly increased.

Further, rollers are provided on the base to facilitate the overall movement of the frame 10.

The insulation and voltage resistance testing mechanism 30, the thickness testing mechanism 40, and the carrying mechanism 20 in the present embodiment are described in detail below.

1. Insulation voltage-withstand test mechanism

As shown in fig. 3 and 4, in the technical solution of the present embodiment, the insulation and voltage withstand test mechanism 30 includes a first support 31, a first test station 32, two sets of side face pressurizing mechanisms 33, a first end face pressurizing mechanism 34, and a top pressurizing energizing mechanism 35. Wherein the first support 31 is arranged on the frame 10. The first test station 32 is arranged on the first support 31, and the first test station 32 is provided with a conductive structure. Two sets of side pressurizing mechanisms 33 are arranged on the first support 31 and are respectively positioned at two sides of the first test station 32, and conductive structures are arranged on the side pressurizing mechanisms 33. A first end face pressurizing mechanism 34 is disposed on the first support 31 at the front and/or rear of the first test station 32, and an electrically conductive structure is disposed on the first end face pressurizing mechanism 34.

Specifically, when the insulation and voltage test mechanism 30 performs the insulation and voltage test, the conveyance mechanism 20 places the battery 1 on the first test station 32. The two sets of side face pressurizing mechanisms 33 apply pressure to the two small side faces of the battery 1, respectively, the first end face pressurizing mechanism 34 applies pressure to one or both large side faces of the battery 1, the top pressurizing energizing mechanism 35 applies pressure to the top face of the battery 1, and the energizing probes 351 abut against the poles of the battery and release the test current.

Further, the side pressing mechanism 33 is provided with a conductive structure on the pressing surface that contacts the battery 1, and the first end pressing mechanism 34 is provided with a conductive structure on the pressing surface that contacts the battery 1. And the above-mentioned conductive structure is conductive cloth, and conductive cloth and circular telegram probe 351 all are connected with insulating withstand voltage tester, and the circular telegram of circular telegram probe 351 back, and insulating withstand voltage tester can detect whether each conductive cloth has the electric current to pass through to judge whether the blue membrane of battery satisfies insulation standard.

In the present embodiment, the first end face pressurizing mechanism 34 is provided only in one, the first end face pressurizing mechanism 34 is provided on the front side of the first test station 32, a fixed baffle is provided on the rear side of the first test station 32, and the first end face pressurizing mechanism 34 presses the first test station 32 against the fixed baffle, thereby pressing the battery 1.

In the present embodiment, four side pressurizing mechanisms 33 are provided on one side of the four first test stations 32, and four side pressurizing mechanisms 33 are also provided on the other side so as to be adapted to the small sides of the four batteries 1 to be tested. Four energization probes 351 are provided on the top pressurizing energization mechanism 35 so as to be fitted to the top surfaces of the four batteries 1 to be tested.

As can be seen in conjunction with fig. 3, the top pressurization energizing mechanism 35 further includes a top frame disposed at the top of the four first test stations 32, and the top pressurization energizing mechanism 35 further includes a carriage on which the four energizing probes 351 are disposed, the carriage being slidably disposed on the top frame by a linear drive mechanism.

When feeding, the sliding frame slides to avoid the four first testing stations 32, so that the battery 1 can be placed on the first testing stations 32 from top to bottom. After loading is completed, the carriage slides to the upper side of the four first test stations 32. Each energizing probe 351 is connected with a driving cylinder, and the driving cylinders can push the energizing probes 351 downwards, so that the energizing probes 351 can press the top surface of the battery 1 downwards.

As shown in fig. 3 and 4, in the technical solution of the present embodiment, a first sliding rail 311 is disposed on the first support 31. The first test stations 32 are multiple, the first test stations 32 are slidably arranged on the first sliding rail 311, the first test stations 32 are provided with a first conductive partition 321 and a second conductive partition 322, and the first conductive partition 321 and the second conductive partition 322 are respectively abutted against the end faces of two adjacent batteries 1. The side pressurizing mechanisms 33 are multiple, the side pressurizing mechanisms 33 are arranged in one-to-one correspondence with the first test stations 32, the electrifying probes 351 are multiple, and the electrifying probes 351 are arranged in one-to-one correspondence with the first test stations 32.

Specifically, the first test station 32 is provided in plural, so that the plurality of cells 1 can be subjected to the insulation withstand voltage test at a time, thereby improving the test efficiency. In this embodiment, the first test station 32 is provided with four.

As can be seen in conjunction with fig. 4, each first testing station 32 is provided with a first conductive spacer 321 and a second conductive spacer 322, and the two conductive spacers are disposed along a vertical direction, so that the first testing station 32 has an "L" structure. The two conductive clapboards are connected with an insulation voltage withstand tester. Further, the plurality of first test stations 32 are independently slidable therebetween. In performing the test, the battery 1 is placed on the first test station 32, the bottom surface of the battery 1 is in contact with the conductive structures on the first test station 32, the two small sides are in contact with the conductive structures on the side pressurizing mechanism 33, and the top surface is in contact with the energizing probes 351. One large side of the battery 1 is in contact with a first conductive spacer 321 on a first test station 32 and the other large side of the battery 1 is in contact with a second conductive spacer 322 on an adjacent first test station 32. It can be seen that the four sides and the bottom of the battery 1 are connected to the conductive structure, and the top of the battery 1 is in contact with the energizing probe 351.

Further, as will be appreciated by those skilled in the art, in the first test station 32 at the end in the direction toward the first pressurizing seat 341, one large side of the battery 1 on the first test station 32 is in contact with the conductive structure on the first end pressurizing mechanism 34.

Further, the first conductive spacer 321 and the second conductive spacer 322 are separated by a non-conductive structure such that they are non-conductive. And during testing, the conductive structures outside the adjacent batteries 1 are not communicated, and the accuracy of the measurement result is ensured.

As shown in fig. 4 and 5, in the technical solution of the present embodiment, the first end face pressurizing mechanism 34 includes a first pressurizing seat 341 and a first driving cylinder 342, the first pressurizing seat 341 is disposed on the first slide rail 311, and a push rod of the first driving cylinder 342 is connected to the first pressurizing seat 341. The adjacent first test stations 32, and the first test station 32 located at the outermost side and the first pressurizing seat 341 are connected by a first linkage limiting structure 36. The plurality of first test stations 32 have test positions that move in a first direction to approach and press the batteries 1 toward each other, and loading positions that move in a second direction to have a predetermined interval from each other. The first linkage limiting structure 36 is adapted to move synchronously when moving in the second direction with a predetermined distance between adjacent first test stations 32 or between the first test station 32 located at the outermost side and the first pressurizing seat 341.

Specifically, each of the first test stations 32 is independently movable therebetween. When loading is required, the push rod of the first driving cylinder 342 is retracted, so that the first pressurizing seat 341 is moved in the second direction (i.e., right side as viewed in fig. 4). When the relative distance between the first pressurizing seat 341 and the first testing station 32 at the end reaches the preset distance, the first linkage limiting structure 36 makes the relative positions of the two fixed and synchronously move. That is, the first pressurizing seat 341 drives the first testing station 32 at the end to move in the second direction. The movement pattern between the adjacent first test stations 32 is identical to the movement pattern between the first pressurizing seat 341 and the first test station 32 positioned at the end. Therefore, when the push rod of the first driving cylinder 342 is retracted, the first pressurizing seat 341 can drive the four first testing stations 32 to move in the second direction as a whole, and a predetermined distance is kept between the adjacent first testing stations 32.

The adjacent first test stations 32 have a preset distance therebetween, so that the battery 1 is conveniently fed.

When the loading is completed and the voltage-withstanding insulation test is required, the push rods of the first driving cylinders 342 extend, and at this time, the four first testing stations 32 and the movement of the first pressurizing seat 341 are not affected by the first linkage limiting structure 36. When the push rod of the first driving cylinder 342 is extended, the first pressurizing seat 341 is moved toward the first direction (i.e., the left side as viewed in fig. 4). After the first pressurizing seat 341 is in abutting contact with the first testing station 32 located at the end, the first testing station 32 is driven to move towards the first direction. After the adjacent first test stations 32 abut, the whole of the four first test stations 32 moves toward the first direction until abutting against the fixed baffle on the first support 31. The first drive cylinder 342 continues to pressurize, thereby causing the battery 1 on the first test station 32 to be compressed.

As shown in fig. 5, in the technical solution of the present embodiment, the first linkage limiting structure 36 includes a first limiting block 361 and a first limiting rod 362. The front side and the rear side of the first test station 32 are respectively provided with a first limiting block 361 and a first limiting rod 362, the first pressurizing seat 341 is provided with a first limiting block 361 or a first limiting rod 362, adjacent first test stations 32 are linked through the first limiting block 361 and the first limiting rod 362, and the first test station 32 at the outermost side is linked with the first pressurizing seat 341 through the first limiting block 361 and the first limiting rod 362. The first limiting rod 362 extends toward the first limiting block 361, and a first bending section 363 is disposed at an end of the first limiting rod 362 toward the first limiting block 361, and the first bending section 363 stops the first limiting block 361.

As can be seen from fig. 5, in the first pressurizing seat 341 and the first testing station 32 located at the outermost side, the first pressurizing seat 341 is provided with a first stopper rod 362, and the first stopper rod 362 extends toward the first testing station 32. The first test station 32 is provided with a first stopper 361 facing the first pressurizing seat 341. After the end portion of the first limiting rod 362 is bent, the end portion of the first limiting block 361 is stopped at a side facing away from the first pressurizing seat 341.

Based on the above-described structure, it will be understood by those skilled in the art that when the battery 1 is compressed between the first pressurizing seat 341 and the first testing station 32, the first stopper 361 is spaced apart from the first bending section 363, and the two are not in contact. When the test is completed and the feeding is required, the first driving cylinder 342 drives the first pressurizing seat 341 to move outwards, the distance between the first pressurizing seat 341 and the first testing station 32 is gradually increased, and the distance between the first bending section 363 and the first limiting block 361 is gradually reduced. Until the first bending section 363 contacts with the first limiting block 361, the first pressurizing seat 341 can drive the first testing station 32 to move outwards and to a preset position.

It can be seen that the length of the first stopper rod 362 determines the size of the predetermined distance between the first pressurizing seat 341 and the first testing station 32.

Of course, the first limiting rod 362 and the first limiting block 361 may be positioned opposite to each other, that is, the first limiting rod 362 is disposed on the first testing station 32, and the first limiting block 361 is disposed on the first pressurizing seat 341. At this time, the first bending section 363 is limited at a side of the first limiting block 361 facing away from the first testing station 32.

As shown in fig. 5, among the adjacent first test stations 32, for convenience of description, the first test station 32 close to the first pressurizing seat 341 is referred to as a first station, and the first test station 32 far from the first pressurizing seat 341 is referred to as a second station. Wherein, be provided with first gag lever post 362 on the second station, first gag lever post 362 extends towards the second station. One side of the second station facing the first station is provided with a first limiting block 361. After the end part of the first limiting rod 362 is bent, the end part of the first limiting rod 361 is stopped at one side, which is away from the first station, of the first limiting block 361.

Based on the above structure, it will be understood by those skilled in the art that when the battery 1 is compressed between the first station and the second station, the first stopper 361 is spaced from the first bending section 363, and the two are not in contact. When the test is completed and the feeding is required, the first driving cylinder 342 drives the first station to move outwards, the distance between the first station and the second station is gradually increased, and the distance between the first bending section 363 and the first limiting block 361 is gradually reduced. Until the first bending section 363 is in contact with the first limiting block 361, the first station can drive the second station to move outwards and to a preset position.

It can be seen that the length of the first stop bar 362 determines the size of the predetermined distance between the first and second stations.

Of course, the first limiting rod 362 and the first limiting block 361 may be positioned in opposite directions, that is, the first limiting rod 362 is disposed on the second station, and the first limiting block 361 is disposed on the first station. At this time, the first bending section 363 is limited at one side of the first limiting block 361 facing away from the second station.

2. Thickness testing mechanism

As shown in fig. 6, in the technical solution of the present embodiment, the thickness testing mechanism 40 includes a second support 41, a second testing station 42, a second end face pressing mechanism 43, and a measurement sensor 44. Wherein the second support 41 is arranged on the frame 10. The second test station 42 is arranged on the second support 41, and the second end face pressing mechanism 43 is arranged on the front side and/or the rear side of the second test station 42. A measuring sensor 44 is provided on the second support 41, the measuring sensor 44 being adapted to measure the thickness of the battery 1.

In performing the test, the battery 1 is placed on the second test station 42, and the second end face pressing mechanism 43 is capable of pressing the large side face of the battery, thereby pressing the battery 1. The measurement sensor 44 measures the thickness of the compressed battery 1.

In the present embodiment, the second end face pressing mechanism 43 is provided only on the front side of the battery 1, and the rear side of the battery 1 is stopped by the fixed shutter. Therefore, the battery 1 can be clamped by only one second end face pressing mechanism 43.

Of course, in some embodiments not shown, the second end face pressing mechanism 43 may be provided only on the rear side of the battery 1, and the shutter may be provided on the front side of the battery 1. Alternatively, one second end face pressing mechanism 43 is provided on each of the front side and the rear side of the battery 1.

As shown in fig. 6 to 8, in the technical solution of the present embodiment, the second support 41 is provided with a second slide rail 411. The second test stations 42 are multiple, the plurality of second test stations 42 are slidably disposed on the second slide rail 411, and the second test stations 42 are provided with partition plates 421, and the partition plates 421 are abutted with adjacent batteries 1.

Specifically, by providing a plurality of second test stations 42, a plurality of batteries 1 can be detected at a time, thereby improving the detection efficiency.

As shown in fig. 6, the partition plate 421 is provided vertically, and when the thickness test is performed, the battery 1 is placed on the second test station 42, and one large side of the battery 1 abuts against the partition plate 421. As will be appreciated by those skilled in the art in conjunction with fig. 6, in the outermost second test station 42, one large side surface of the battery 1 abuts the partition plate 421, and the other large side surface abuts the second end surface pressing mechanism 43. In the adjacent second test stations 42, the two large sides of the battery 1 are respectively abutted against the partition plates 421 on the adjacent two second test stations 42. This enables the plurality of cells 1 to be compacted when performing the thickness test of the cells 1.

As shown in fig. 6 to 8, in the technical solution of the present embodiment, the second end face pressing mechanism 43 includes a second pressing seat 431 and a second driving cylinder 432. The second pressurizing seat 431 is disposed on the second slide rail 411, and a push rod of the second driving cylinder 432 is connected to the second pressurizing seat 431. The adjacent second testing stations 42 and the second testing station 42 positioned at the outermost side are connected with the second pressurizing seat 431 through a second linkage limiting structure 45. The plurality of second test stations 42 have test positions that move toward the third direction to approach each other and press the battery 1, and loading positions that move toward the fourth direction to have a predetermined interval from each other, and the second interlocking limit structure 45 is adapted to move synchronously while moving toward the fourth direction and having a predetermined distance between adjacent second test stations 42, or between the outermost second test station 42 and the second pressurizing seat 431.

Specifically, each of the second test stations 42 is independently movable therebetween. When loading is required, the push rod of the second driving cylinder 432 is retracted, so that the second pressurizing seat 431 is moved in the fourth direction (i.e., right side as viewed in fig. 6). When the relative distance between the second pressurizing seat 431 and the second testing station 42 at the end reaches the preset distance, the second linkage limiting structure 45 makes the relative positions of the two fixed and synchronously move. That is, the second pressing seat 431 drives the second testing station 42 at the end to move in the fourth direction. The movement pattern between the adjacent second test stations 42 is identical to the movement pattern between the second pressing seat 431 and the second test station 42 located at the end. Therefore, when the push rod of the second driving cylinder 432 is retracted, the second pressurizing seat 431 can drive the whole four second testing stations 42 to move in the fourth direction, and the preset distance between the adjacent second testing stations 42 is kept.

The adjacent second test stations 42 have a preset distance therebetween, so that the battery 1 is conveniently fed.

When the thickness test is required to be performed after the loading is completed, the push rods of the second driving cylinders 432 extend, and at this time, the movements of the four second test stations 42 and the second pressurizing seat 431 are not affected by the second linkage limiting structure 45. When the push rod of the second driving cylinder 432 is extended, the second pressurizing seat 431 is moved toward the third direction (i.e., the left side as viewed in fig. 6). After the second pressurizing seat 431 is in abutting contact with the second testing station 42 positioned at the end, the second testing station 42 is driven to move towards the third direction. After the adjacent second test stations 42 abut, the whole of the four second test stations 42 moves toward the third direction until abutting against the fixed baffle on the second support 41. The second drive cylinder 432 continues to pressurize, thereby causing the battery 1 on the second test station 42 to be compressed.

As shown in fig. 6 to 8, in the technical solution of the present embodiment, the second linkage limiting structure 45 includes a second limiting block 451 and a second limiting rod 452. The front and rear sides of the second testing station 42 are respectively provided with a second limiting block 451 and a second limiting rod 452, the second pressurizing seat 431 is provided with a second limiting block 451 or a second limiting rod 452, adjacent second testing stations 42 are linked through the second limiting block 451 and the second limiting rod 452, and the second testing station 42 located at the outermost side is linked with the second pressurizing seat 431 through the second limiting block 451 and the second limiting rod 452. The second limiting rod 452 extends towards the second limiting block 451, and a second bending section 453 is arranged at the end of the second limiting rod 452 towards the second limiting block 451, and the second bending section 453 stops the second limiting block 451.

After the end portion of the second limiting rod 452 is bent, the end portion of the second limiting block 451 is stopped at a side, away from the second pressurizing seat 431, of the second limiting block 451.

Based on the above structure, it will be understood by those skilled in the art that when the battery 1 is compressed between the second compression seat 431 and the second testing station 42, the second stopper 451 is spaced from the second bending portion 453, and the second stopper 451 is not in contact with the second bending portion 453. When the test is completed and the feeding is required, the second driving cylinder 432 drives the second pressing seat 431 to move outwards, the distance between the second pressing seat 431 and the second test station 42 is gradually increased, and the distance between the second bending section 453 and the second limiting block 451 is gradually reduced. Until the second bending section 453 contacts the second limiting block 451 in an abutting manner, the second pressurizing seat 431 can drive the second testing station 42 to move outwards and to a preset position.

It can be seen that the length of the second stop lever 452 determines the size of the predetermined distance between the second pressing seat 431 and the second test station 42.

Of course, the second limiting rod 452 and the second limiting block 451 may be positioned opposite to each other, that is, the second limiting rod 452 is disposed on the second testing station 42, and the second limiting block 451 is disposed on the second pressing seat 431.

Wherein, be provided with second gag lever post 452 on the second station, second gag lever post 452 extends towards the second station. A second stop block 451 is provided on the side of the second station facing the first station. After the end portion of the second limiting rod 452 is bent, the second limiting rod 451 is stopped at one side of the second limiting rod away from the first station.

Based on the above structure, it will be understood by those skilled in the art that when the battery 1 is compressed between the first station and the second station, the second stopper 451 is spaced from the second bending portion 453, and the two are not in contact. When the test is completed and the feeding is required, the second driving cylinder 432 drives the first station to move outwards, the distance between the first station and the second station is gradually increased, and the distance between the second bending section 453 and the second limiting block 451 is gradually reduced. Until the second bending section 453 contacts the second limiting block 451 in an abutting manner, the first station can drive the second station to move outwards and to a preset position.

It can be seen that the length of the second stop lever 452 determines the size of the predetermined distance between the first and second stations.

Of course, the second limiting rod 452 and the second limiting block 451 may be positioned opposite to each other, that is, the second limiting rod 452 is disposed on the second station, and the second limiting block 451 is disposed on the first station. At this time, the second bending section 453 is limited at a side of the second limiting block 451 facing away from the second station.
