Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a quick-change fixture for a lithium battery stacking stage. Background Technology

[0002] Currently, traditional fully automatic or semi-automatic lithium battery stacking machines determine the cell size and width by measuring the distance between the front, back, left, and right pressure plates on the stacking table using a ruler or vernier caliper when changing cell models. Since the pressure plates are fixed to the lifting cylinder with screws, changing from one cell model to another often requires adjusting the distance between the four pressure plates to determine the cell width. The lateral tolerance of the cell width is ±1.5mm. The left and right front and back pressure plates usually lack a reference surface and a fixed surface. It is difficult to adjust the pressure plates to a horizontal plane using a ruler or vernier caliper. Either the left and right front and back pressure plates are offset to the left or right, failing to form a regular square or rectangle, often resulting in a slanted quadrilateral. This causes the separator of the stacked cell to not cover the negative or positive electrode, resulting in exposed cells, black edges, and short circuits, leading to unqualified cells. It is necessary to adjust the four pressure plates of the stacking table multiple times and measure the distance between the pressure plates to ensure that the cell size is within the process range. Utility Model Content

[0003] Based on this, the present invention provides a quick-change fixture for lithium battery stacking tables, which aims to solve the problems of complex operation and easy stacking deviation in existing battery stacking machines when changing models, resulting in exposed cells, black edges, or even short circuits and failure to meet standards.

[0004] To achieve the above objectives, the present invention proposes the following technical solution: a quick-change fixture for a lithium battery stacking table, comprising an integrated plate, an adjustable stop bar, a first scale, and a second scale;

[0005] The integrated board includes a board body, a first fixing strip, a stacking platform, and a second fixing strip; the first fixing strip, the second fixing strip, and the stacking platform are all disposed on one side of the board body, the first fixing strip and the second fixing strip are symmetrically disposed at both ends of the side, the stacking platform is disposed between the first fixing strip and the second fixing strip, and the stacking platform is connected to the first fixing strip and the second fixing strip respectively;

[0006] The first scale and the second scale are symmetrically arranged on both sides of the stacking table; one end of the adjustable stop bar is slidably connected to one side of the plate body, and the other end of the adjustable stop bar is slidably connected to the other side of the plate body.

[0007] In a preferred embodiment, the plate, the first fixing strip, the stacking platform, and the second fixing strip are integrally formed; the first fixing strip and the second fixing strip both protrude from the stacking platform.

[0008] In a preferred embodiment, the end corner of the first fixing bar connected to the stacking table forms a first pressing claw and a second pressing claw; the end corner of the adjustable stop bar connected to the stacking table forms a third pressing claw and a fourth pressing claw; the first pressing claw and the third pressing claw are arranged opposite to each other, and the second pressing claw and the fourth pressing claw are arranged opposite to each other.

[0009] In a preferred embodiment, a mating stacking step opening is provided on the side of the plate away from the stacking table, and the mating stacking step opening is provided at one end near the first fixing strip.

[0010] In a preferred embodiment, the adjustable stop bar is arranged parallel to the first fixed bar and the second fixed bar, and the adjustable stop bar is positioned above the first scale and the second scale.

[0011] In a preferred embodiment, a gap is provided between the adjustable baffle and the stacking table.

[0027] Specifically, such as Figures 1 to 3 As shown, the present invention proposes the following technical solution: a quick-change fixture for a lithium battery stacking table, comprising an integrated plate 10, an adjustable stop bar 20, a first scale 30, and a second scale 40.

[0028] The integrated board 10 includes a board body 11, a first fixing strip 12, a stacking platform 13, and a second fixing strip 14. The first fixing strip 12, the second fixing strip 14, and the stacking platform 13 are all disposed on one side of the board body 11. The first fixing strip 12 and the second fixing strip 14 are symmetrically disposed at both ends of the side. The stacking platform 13 is disposed between the first fixing strip 12 and the second fixing strip 14, and the stacking platform 13 is connected to the first fixing strip 12 and the second fixing strip 14 respectively.

[0029] The first scale 30 and the second scale 40 are symmetrically arranged on both sides of the stacking platform 13; one end of the adjustable stop bar 20 is slidably connected to one side of the plate 11, and the other end of the adjustable stop bar 20 is slidably connected to the other side of the plate 11.

[0030] In a preferred embodiment, the plate 11, the first fixing strip 12, the stacking platform 13, and the second fixing strip 14 are integrally formed; the first fixing strip 12 and the second fixing strip 14 both protrude from the stacking platform 13. This allows the first pressure claw 50 and the second pressure claw 60 to be fixed on a reference surface, facilitating cell replacement.

[0031] In a preferred embodiment, the end corner where the first fixing bar 12 connects to the stacking platform 13 forms a first pressure claw 50 and a second pressure claw 60; the end corner where the adjustable stop bar 20 connects to the stacking platform 13 forms a third pressure claw 70 and a fourth pressure claw 80; the first pressure claw 50 and the third pressure claw 70 are arranged opposite to each other, and the second pressure claw 60 and the fourth pressure claw 80 are arranged opposite to each other. This allows the first pressure claw 50, the second pressure claw 60, the third pressure claw 70, and the fourth pressure claw 80 to be quickly fixed on a reference surface, facilitating cell replacement.

[0032] In a preferred embodiment, a mating stacking step opening (not shown in the figure) is provided on the side of the plate 11 away from the stacking table 13, and the mating stacking step opening is located at one end near the first fixing strip 12. This facilitates the fixing of the clamp.

[0033] In a preferred embodiment, the adjustable stop bar 20 is arranged parallel to the first fixed bar 12 and the second fixed bar 14, and the adjustable stop bar 20 is positioned above the first scale 30 and the second scale 40.

[0034] In a preferred embodiment, a gap is provided between the adjustable baffle 20 and the stacking table 13.

[0035] In a preferred embodiment, the adjustable baffle 20 has a recess 21 on its side near the stacking table 13, and the recess 21 covers the stacking table 13.

[0036] In a preferred embodiment, the length of the recess 21 is greater than the width of the stacking platform 13; the recess 21 and the adjustable stop bar 20 are integrally formed. This arrangement facilitates the movement of the adjustable stop bar, allowing the first pressure claw 50, the second pressure claw 60, the third pressure claw 70, and the fourth pressure claw 80 to be quickly fixed on a reference surface.

[0037] In a preferred embodiment, a first linear slider 111 is provided on one side of the plate 11, and a first guide rail 1111 is provided on the first linear slider 111; a second linear slider 112 is provided on the other side of the plate 11, and a second guide rail 1121 is provided on the second linear slider 112; one end of the adjustable stop bar 20 is slidably connected to the first guide rail 1111, and the other end is slidably connected to the second guide rail 1121.

[0038] In a preferred embodiment, the first linear slider 111 and the second linear slider 112 are symmetrically arranged; the first guide rail 1111 and the second guide rail 1121 are symmetrically arranged.

[0039] When using the structure of this application, the first pressure claw 50 and the second pressure claw 60 remain stationary on the reference surface. Then, according to the width of the battery cell, the adjustable stop bar 20 is moved to the corresponding position on the first scale 30 and the second scale 40. Finally, the width of the battery cell is determined according to the distance of the adjustable stop bar 20. The accuracy of the battery cell width can be ±0.5mm. After confirming that the size is correct, the adjustable stop bar 20 can be fixed on the stacking table 13 by tightening the fixing screw 22 on the adjustable stop bar 20. This also ensures that the four pressure claws are arranged in pairs on the same reference surface.

[0040] The structure of this application solves the problem of not needing to measure multiple times with a ruler and calipers when changing models. The adjustable stop bar can be slid directly to the required size, which not only saves measurement time, but also avoids the risk of cell short circuits caused by repeated measurement errors during the stacking process. It is both simple and fast.
