[0002] With the development of the new energy industry, the national standard extrusion test for battery packs has become a must-do for lithium-ion batteries before they are released to the market, and OEMs attach great importance to this test. To ensure the best performance in the extrusion test, the position and angle of the battery pack on the extrusion platform, as well as the position of the extrusion tooling, are crucial.

[0036] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0037] As described in the background technology, current battery packs 200 basically need to undergo national standard extrusion tests. When the existing battery packs 200 undergo the national standard compulsory inspection extrusion test, they are generally manually operated by the hoist to directly lift the battery pack 200 onto the extrusion platform for extrusion testing. The extrusion platform is often an integral structure, and the extrusion platform cannot adjust the position of the battery pack 200, which often causes gaps and deflections in the battery pack 200 on the extrusion platform, ultimately resulting in inaccurate extrusion test results.

[0038] In view of this, an embodiment of the present invention provides a battery pack extrusion tool 10 and system, adjusts the position of the battery pack 200 through a movable mechanism 12, and calibrates the position of the battery pack 200 with a first sensor group 15 and a second sensor group 16, thereby reducing the deflection between the battery pack 200 and the extrusion force wall 11, thereby making the results of the extrusion test more accurate.

[0039] The following is an exemplary description of the battery pack extrusion tool 10 provided in an embodiment of the present invention:

[0040] See also Figure 1 , Figure 1 The present invention provides a schematic structural diagram of a battery pack extrusion tool 10, which includes an extrusion force wall 11, a movable mechanism 12, a first frame 13, a bearing seat 14, a first sensor group 15, and a second sensor group 16. The bearing seat 14 is arranged between the movable mechanism 12 and the first frame 13. The movable mechanism 12 can rotate with the bearing seat 14. The first sensor group 15 is arranged on the first frame 13 to detect whether the battery pack 200 is in contact with the extrusion force wall 11. Whether aligned, the movable mechanism 12 includes a second frame 121 and a battery pack placement table 122, the battery pack placement table 122 is used to place the battery pack 200, the second frame 121 is provided with a slide rail 1211, the slide rail 1211 is installed with a slider 1212, the slider 1212 is fixedly connected to the battery pack placement table 122, the battery pack placement table 122 can move along the slide rail 1211, and the second sensor group 16 is provided on the extrusion force wall 11, for detecting whether the battery pack 200 is tightly attached to the extrusion force wall 11.

[0041] Depend on Figure 1It can be seen that the extrusion stress wall 11 is fixed in one place. When the battery pack 200 is subjected to an extrusion stress test, one side of the battery pack 200 is subjected to an extrusion stress, and the extrusion stress wall 11 resists the opposite side of the stress-bearing surface of the battery pack 200, and then the battery pack 200 is subjected to an extrusion test. The extrusion stress wall 11 can be a wall or a steel plate, as long as it is a hard object that can be fixed. The first frame 13 is a fixed surface bottom plate for carrying the movable mechanism 12. The movable mechanism 12 can rotate on the first frame. The first frame 13 and the movable mechanism 12 are connected by a bearing seat 14. The bearing seat 14 contains a bearing inside. The movable mechanism 12 can be easily rotated through the bearing seat 14. The first frame 13 can preferably be a rectangular plate, perpendicular to the extrusion stress wall 11, forming a right angle. A first sensor group 15 is provided on the first rack 13 , and the first sensor group 15 is also fixedly arranged, that is, the positions of the extrusion force wall 11 , the first rack 13 , and the first sensor group 15 are all fixed. The first sensor group 15 can detect whether the battery pack 200 is parallel to the extrusion force wall 11 .

[0042] The movable mechanism 12 includes a second frame 121 and a battery pack placement platform 122. Specifically, the bearing seat 14 is connected to the second frame 121. A slide rail 1211 is provided on the second frame 121. The battery pack placement platform 122 is slidably connected to the slide rail 1211 and the second frame 121 through a slider 1212. The battery pack 200 is placed on the battery pack placement platform 122.

[0043] In actual operation, the initial position of the battery pack placement platform 122 is a certain distance away from the extrusion stress wall 11. First, the battery pack 200 is placed on the battery pack placement platform 122, and the battery pack placement platform 122 is moved toward the extrusion stress wall 11. When the first sensor group 15 senses the battery pack 200, the battery pack placement platform 122 stops moving. The first sensor group 15 checks whether the battery pack 200 is aligned parallel to the extrusion stress wall 11. If it is aligned, the battery pack placement platform 122 continues to be moved. When the second sensor group 16 senses that the battery pack 200 is close to the extrusion stress wall 11, it stops moving; if it is not aligned, the second rack 121 is rotated until the battery pack 200 is aligned with the extrusion stress wall 11, and then the battery pack placement platform 122 continues to be moved toward the extrusion stress wall 11.

[0044] The battery pack extrusion tool 10 provided in the embodiment of the present invention can adjust the position of the battery pack 200 on the battery pack placement table 122 by rotating the second frame 121 of the movable mechanism 12 and moving the battery pack placement table 122, and verify whether the battery pack 200 is aligned with the extrusion stress wall 11 through the first sensor group 15, and sense whether the battery pack 200 is close to the extrusion stress wall 11 through the second sensor group 16, thereby completing the placement and installation of the battery pack 200 for the extrusion test. During the extrusion test, the battery pack 200 can be aligned as parallel as possible with the extrusion stress wall 11, thereby making the results of the extrusion test more accurate.

[0045] In a possible implementation, the second rack 121 can also automatically rotate according to the detection result of the first sensor group 15, see Figure 2 , Figure 2 A structural schematic diagram of a battery pack extrusion tool 10 including a motor is provided in an embodiment of the present invention. The battery pack extrusion tool 10 can also include a first motor 17. The first motor 17 is connected to the bearing seat 14. Turning on the first motor 17 can drive the bearing seat 14 to rotate, and then drive the movable mechanism 12 to rotate.

[0046] The first motor 17 can be manually controlled using a switch button. When the battery pack 200 is not aligned with the extrusion stress wall 11, the operator turns on the first motor 17, drives the bearing seat 14 to rotate, and then drives the movable mechanism 12 to rotate until the battery pack 200 is aligned with the extrusion stress wall 11, and stops the first motor 17; preferably, the first motor 17 and the first sensor group 15 can also be communicated with the controller. The controller controls the start and stop of the first motor 17 according to the verification data of the first sensor group 15, and can more accurately control the rotation of the second frame 121.

[0047] Furthermore, the movable mechanism 12 may also include a second motor 18, which is mounted on the second frame 121. The battery pack placement platform 122 is connected to the second motor 18 via a connecting rod 181. Turning on the second motor 18 can move the battery pack placement platform 122. The configuration and control of the second motor 18 can be similar to that of the first motor 17 and will not be further described here.

[0048] By controlling the first motor 17 and / or the second motor 18 , the position of the battery pack 200 can be adjusted more quickly and accurately to achieve the purpose of aligning the battery pack 200 with the extrusion force-bearing wall 11 .

[0049] In a possible implementation, in order to make the battery pack placement platform 122 more stable, refer to Figure 3 , Figure 3Another structural schematic diagram of a battery pack extrusion tool 10 provided in an embodiment of the present invention, the battery pack placement table 122 may include a bracket 1221, a placement table 1222, a cylinder 1223 and a telescopic rod 1224, the bracket 1221 and the placement table 1222 are connected by the telescopic rod 1224, the cylinder 1223 is arranged between the bracket 1221 and the placement table 1222, and the cylinder 1223 can lift the placement table 1222.

[0050] The movable mechanism 12 may further include a third frame 123 , which is arranged on the second frame 121 , and is provided with rollers 1231 , and the placement platform 1222 is provided with a slide groove 12221 corresponding to the rollers 1231 , and the placement platform 1222 is placed on the third frame 123 through the rollers 1231 .

[0051] The telescopic rod 1224 includes a guide rod 12241 and a guide seat 12242 . The guide rod 12241 is disposed on the placement platform 1222 , and the guide seat 12242 is disposed on the bracket 1221 .

[0052] Depend on Figure 3 As can be seen, the bracket 1221 is connected to the second frame 121 via the slider 1212 and the slide rail 1211. The bracket 1221 is connected to the placement table 1222 via the telescopic rod 1224 and supports the placement table 1222. The third frame 123 supports both ends of the placement table 1222. The bracket 1221 is also provided with a cylinder 1223, which can lift the placement table 1222 to facilitate the movement of the battery pack placement table 1222. Furthermore, the third frame 123 is provided with a row of rollers 1231. The placement table 1222 has a slide groove 12221 corresponding to the roller 1231. The cylinder 1223 lifts the placement table 1222, reducing friction between the placement table 1222, the third frame 123, and the upper surface of the roller 1231. The slide groove 12221 and the roller 1231 allow the battery pack placement table 122 to be smoothly moved. The arrangement of the battery pack placement platform 122 and the third rack 123 can well support the battery pack placement platform 122 without affecting the sliding of the battery pack placement platform 122 .

[0053] Further, see Figure 4 The extrusion stress-bearing wall 11 may be provided with a slot 111 , the slot 111 being opposite to the battery pack placement platform 122 , and the battery pack placement platform 122 may pass through the slot 111 .

[0054] By opening the slot 111 on the extrusion stress wall 11, the battery pack placement platform 122 can pass through the wall when necessary. For example, if the position where the battery pack 200 is placed on the sky is far away from the extrusion stress wall 11, the battery pack 200 may be far away from the extrusion stress wall 11. In this case, it is necessary to continue to move the battery pack placement platform 122 through the extrusion stress wall 11 so that the battery pack 200 can be close to the extrusion stress wall 11.

[0055] Optionally, the first sensor group 15 may include two first sensors, and a connecting line of the two first sensors is parallel to the extrusion-bearing wall 11 .

[0056] The design of the first sensor group 15 allows the use of two first sensors at positions with equal vertical distances from the pair of extrusion stress walls 11 to simultaneously check whether the battery pack 200 is aligned with the extrusion stress wall 11, which can be more accurate and reduce the possibility of inspection errors.

[0057] Optionally, the second sensor group 16 may include two second sensors. As above, the provision of two second sensors can more accurately detect whether the battery pack 200 is pressed against the load-bearing wall 11 .

[0058] In the extrusion test, the battery pack 200 is placed on the placement table 1222, the cylinder 1223 is started, the cylinder 1223 lifts the placement table 1222, the first motor 17 is started, and the battery pack placement table 122 moves along the slide rail 1211 and the roller 1231 toward the extrusion force wall 11. When the first sensor group 15 senses the battery pack 200, the first motor 17 stops, and the first sensor group 15 senses whether the battery pack 200 is aligned with the extrusion force wall 11. If not, the second motor 18 is started, and the second motor 18 passes The bearing seat 14 drives the entire movable mechanism 12 to rotate until the battery pack 200 is aligned with the extrusion force wall 11, stops the second motor 18, starts the first motor 17, and continues to drive the battery pack placement platform 122 to move along the slide rail 1211 and the roller 1231 toward the extrusion force wall 11. When the second sensor group 16 senses that the battery pack 200 is close to the extrusion force wall 11, stops the first motor 17, starts the cylinder 1223, and the placement platform 1222 falls and contacts the third frame 123, completing the alignment and placement of the battery pack 200.

[0059] Furthermore, an embodiment of the present invention also provides a battery pack 200 extrusion system, including a battery pack extrusion tool 10 and a battery pack 200 clamping device, the battery pack 200 clamping device is used to clamp the battery pack 200 and place it on the battery pack placement table 122 of the battery pack extrusion tool 10 and remove the battery pack 200 from the battery pack placement table 122 of the battery pack extrusion tool 10.

[0060] In summary, an embodiment of the present invention provides a battery pack extrusion tool 10 and a system, wherein the battery pack extrusion tool 10 includes an extrusion force wall 11, a movable mechanism 12, a first frame 13, a bearing seat 14, a first sensor group 15 and a second sensor group 16, the movable mechanism 12 includes a second frame 121 and a battery pack placement table 122, the second frame 121 is provided with a slide rail 1211, the slide rail 1211 is installed with a slider 1212, the slider 1212 is fixedly connected to the battery pack placement table 122, the battery pack extrusion tool 10 may further include a first motor 17, a second motor 18, and a third frame 123, the battery pack placement table 122 includes a bracket 1221, a placement table 1222, a cylinder 1223 and a telescopic rod 1224, a roller 1231 is provided on the third frame 123, and the placement table 1222 is provided with a slide groove 12221 corresponding to the roller 1231. By rotating and moving the movable mechanism 12, the first sensor group 15 and the second sensor group 16 calibrate the battery pack 200, thereby reducing the deflection between the battery pack 200 and the extrusion force wall 11, thereby making the results of the extrusion test more accurate and providing good support for the battery pack 200.
