Description

Technical Field

[0001] This utility model relates to the field of stacked battery cell testing technology, and in particular to a stacked battery cell pressing and straightening mechanism. Background Technology

[0002] Currently, most laminated battery cells undergo hot pressing and aluminum foil wrapping before X-ray inspection. This process ensures sufficient rigidity and stable layer structure, preventing displacement and damage during high-speed operation. However, laminated cells that haven't undergone hot pressing and aluminum foil wrapping suffer from insufficient stability during high-speed inspection, failing to meet the demands of high-speed testing. The additional positioning process disrupts the overall equipment's operating cycle, thus impacting overall inspection efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a pressing and straightening mechanism for laminated battery cells, which solves the problem that the high-speed flow of the laminated layers can easily affect the test results when laminated battery cells that have not undergone hot pressing and aluminum foil wrapping are tested.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stacked battery cell clamping and straightening mechanism is provided. The stacked battery cells to be inspected arrive at the inspection position via a cell conveyor line. The stacked battery cell clamping and straightening mechanism includes a mounting bracket, an elastic clamping component, and a limiting component, wherein:

[0006] The elastic clamping assembly is mounted on the mounting bracket. The elastic clamping assembly includes an upper pressure plate, which is used to press against the upper surface of the stacked battery cell when the stacked battery cell reaches the detection position.

[0007] The limiting assembly includes side baffles mounted on the upper pressure plate, which are used to abut against at least two sides of the stacked cell when the cell reaches the detection position.

[0008] As an alternative, the cell conveying line is equipped with a lifting module for lifting the stacked cells to a set height. When the stacked cells are lifted to the set height, they reach the detection position, and the upper pressure plate is suspended directly above the lifting module.

[0009] As an alternative, the elastic clamping assembly also includes a support plate, and a spring guide post passing through the support plate is provided on the upper pressure plate. The spring guide post is used to make the upper pressure plate float up and down relative to the support plate.

[0010] As an optional solution, the lifting module is equipped with a rotating part. When the stacked cells are detected at the detection position, the rotating part drives them to rotate. The support plate is equipped with a rotating shaft that is rotatably connected to the mounting bracket. The mounting bracket is equipped with a rotary motor, and the output shaft of the rotary motor is connected to the rotating shaft. The rotary motor is used to drive the upper pressure plate to rotate with the stacked cells.

[0011] As an alternative, the mounting bracket is equipped with an origin sensor, and the support plate is equipped with a sensing plate. The sensing plate is used to trigger the origin sensor, so that the rotating upper pressure plate returns to the origin position.

[0012] As an alternative, the two side baffles act on two opposite sides of the laminated cell respectively. The side baffles are fixed on the connecting plate, which is connected to the upper pressure plate by bolts. The connecting plate has elongated holes, which make the distance between the two side baffles adjustable.

[0013] As an optional solution, the mounting bracket includes support rods and a lifting adjustment plate. The two support rods are distributed on both sides of the cell conveying line, and the elastic clamping assembly is installed on the lifting adjustment plate. The lifting adjustment plate can slide and lock along the support rods, so that the distance from the upper pressure plate to the detection position is adjustable.

[0014] As an alternative, the stacked cells are loaded by jigs and fixtures and flow on the cell conveyor line. Different batches of stacked cells use different models of jigs and fixtures. The support rods are equipped with scale markings that correspond one-to-one with the model of the jigs and fixtures. The scale markings are used to help determine the position of the lifting adjustment plate so that the stacked cells of the same batch are subjected to the same degree of pressure from the upper pressure plate.

[0015] The beneficial effects of this utility model are:

[0016] This stacked cell clamping and straightening mechanism compacts the stacked cells by providing top pressure through an elastic clamping component during the process of the stacked cells reaching the inspection position, and maintains the structural stability of the stacked cells through a limiting component. It does not add an extra positioning process and does not affect the overall equipment's operating cycle time, providing a reliable technical guarantee for high-cycle, high-stability X-ray stacked cell inspection.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0032] Please see Figures 1 to 4 As shown, this embodiment provides a stacked battery cell clamping and straightening mechanism. The stacked battery cell 4 to be inspected arrives at the inspection position via a battery cell conveyor line. The stacked battery cell clamping and straightening mechanism includes a mounting bracket 1, an elastic clamping component 2, and a limiting component 3, wherein:

[0033] The elastic clamping assembly 2 is mounted on the mounting bracket 1. The elastic clamping assembly 2 includes an upper pressure plate 21, which is used to press against the upper surface of the stacked battery cell 4 when the stacked battery cell 4 reaches the detection position.

[0034] The limiting assembly 3 includes a side baffle 31 mounted on the upper pressure plate 21, which is used to abut against at least two sides of the stacked cell 4 when the stacked cell 4 reaches the detection position.

[0035] Therefore, during the process of the stacked battery cell 4 reaching the detection position, the elastic clamping component 2 provides top pressure to compact the stacked battery cell 4, and the limiting component 3 maintains the structural stability of the stacked battery cell 4. No additional positioning process is required, and the overall equipment operation cycle is not affected. This provides a reliable technical guarantee for the X-ray detection of the stacked battery cell 4 with high cycle time and high stability.

[0036] In some embodiments, a lifting module is provided on the cell conveying line for lifting the stacked cells 4 to a set height. When the stacked cells 4 are lifted to the set height, they reach the detection position, and the upper pressure plate 21 is suspended directly above the lifting module.

[0037] Therefore, in conjunction with the inherent upward movement of the stacked battery cell 4 during testing, an elastic clamping component 2 is set on the upward path of the stacked battery cell 4, and gradually contacts the upper pressure plate 21 as the stacked battery cell 4 reaches the testing position. The stacked battery cell 4 is clamped by the elastic top pressure of the upper pressure plate 21, thereby ensuring the structural stability of the stacked battery cell 4.

[0038] In some other embodiments, the stacked cell 4 does not rise. In this case, the upper pressure block in the elastic clamping assembly 2 can be added with a downward function. As the upper pressure block moves downward, it gradually comes into contact with the stacked cell 4 and is clamped by the elastic top pressure of the upper pressure plate 21, thereby ensuring the structural stability of the stacked cell 4.

[0039] In order to achieve elastic contact between the upper pressure plate 21 and the stacked battery cell 4 and provide top pressure, the elastic clamping assembly 2 also includes a support plate 22. The upper pressure plate 21 is provided with a spring guide post 23 passing through the support plate 22. The spring guide post 23 is used to make the upper pressure plate 21 float up and down relative to the support plate 22.

[0040] Furthermore, the lifting module is provided with a rotating part. When the stacked battery cell 4 is detected at the detection position, it is driven to rotate by the rotating part. The support plate 22 is provided with a rotating shaft 24 that is rotatably connected to the mounting bracket 1. The mounting bracket 1 is provided with a rotary motor 25. The output shaft of the rotary motor 25 is connected to the rotating shaft 24. The rotary motor 25 is used to drive the upper pressure plate 21 to rotate with the stacked battery cell 4.

[0041] According to the testing requirements, the stacked cell 4 needs to rotate a certain angle at the testing position. Taking 45° as an example, the upper pressure block that applies pressure to the stacked cell 4 also needs to have the ability to follow up. Therefore, the support plate 22 is driven by the rotary motor 25 to drive the upper pressure plate 21 to rotate synchronously relative to the stacked cell 4.

[0042] Furthermore, an origin sensor 11 is provided on the mounting bracket 1, and an induction plate 26 is provided on the support plate 22. The induction plate 26 is used to trigger the origin sensor 11, so that the rotating upper pressure plate 21 returns to the origin position.

[0043] This allows the stacked cell pressing and straightening mechanism to accurately reset after each test, so that the next stacked cell 4 can be pressed and straightened.

[0044] In some embodiments, the two side baffles 31 act on two opposite sides of the stacked cell 4 respectively. The side baffles 31 are fixed on the connecting plate 32. The connecting plate 32 is connected to the upper pressure plate 21 by bolts. The connecting plate 32 has an elongated hole 33, so that the distance between the two side baffles 31 is adjustable.

[0045] Specifically, the position and number of side baffles 31 can be adjusted according to the specific shape of the laminated cell 4 to ensure that the laminated layers of the laminated cell 4 will not be displaced or damaged, thus ensuring structural stability.

[0046] In some embodiments, the mounting bracket 1 includes a support rod 12 and a lifting adjustment plate 13. The two support rods 12 are distributed on both sides of the cell delivery line. The elastic clamping assembly 2 is mounted on the lifting adjustment plate 13. The lifting adjustment plate 13 can slide and lock along the support rod 12, so that the distance from the upper pressure plate 21 to the detection position is adjustable.

[0047] Therefore, the stacked cell pressing and straightening mechanism is installed on the cell conveying line, and can adjust the position of the upper pressure plate 21 according to the specifications of the stacked cell 4, thereby adjusting the top pressure of the upper pressure plate 21 on the stacked cell 4.

[0048] Furthermore, the stacked battery cells 4 are loaded by the fixture 5 and flow on the battery cell conveyor line. Different batches of stacked battery cells 4 use different models of fixture 5. The support rod 12 is provided with scale markings that correspond one-to-one with the model of the fixture 5. The scale markings are used to help determine the position of the lifting adjustment plate 13 so that the stacked battery cells 4 of the same batch are subjected to the same degree of pressure from the upper pressure plate 21.

[0049] Therefore, for stacked cells 4 of different specifications, the position of the lifting adjustment plate 13 can be quickly adjusted through the scale markings, reducing the difficulty of operation.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
