[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a tab clamping tool. Background Technology

[0002] In the battery manufacturing process, the stacking of battery cells and the welding of electrode tabs are involved, as well as the reliability verification after the stacking electrode tabs are welded. In order to reduce the finished product loss caused by directly using the welded battery cells for reliability verification, conventional tools such as tweezers are currently used to hold the electrode tabs to simulate the reliability verification after the stacking electrode tabs of the battery cells are welded. However, the stacking electrode tabs and the holding tools are in line contact when using such simple tool holding methods, which makes the electrode tabs easy to deform after stacking, and cannot effectively simulate the actual scenario of stacking electrode tabs welding on the battery cells. Utility Model Content

[0010] In one embodiment of the present invention, the electrode clamping fixture further includes an adjusting member, one end of which is disposed on the fixture base, and the other end of which is disposed on the sliding part and / or the adapter.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1 to 7As shown, the electrode clamping fixture of this utility model is used to clamp stacked electrode tabs 21. The electrode clamping fixture includes a fixture base 1, a first clamping member 2, and a second clamping member 3. The first clamping member 2 and the second clamping member 3 are disposed on the fixture base 1. The stacked electrode tabs 21 are clamped between the first clamping member 2 and the second clamping member 3. The first clamping member 2 and the stacked electrode tabs 21 are in surface contact, as are the second clamping member 3 and the stacked electrode tabs 21.

[0028] This application uses a tab clamping fixture to simulate a battery cell, and welds the stacked tabs 21 clamped on the fixture to facilitate reliability verification of the welded stacked tabs 21, i.e., tensile testing. Specifically, as... Figure 1 As shown, the tab clamping fixture of this application includes a fixture base 1, a first clamping member 2, and a second clamping member 3. Both the first clamping member 2 and the second clamping member 3 are disposed on the fixture base 1, and the stacked tabs 21 are clamped by the pressure between the first clamping member 2 and the second clamping member 3. Furthermore, the first clamping member 2 and the stacked tabs 21 are in surface contact, and the second clamping member 3 and the stacked tabs 21 are in surface contact. The surface contact ensures that the stacked tabs will not deform under the clamping of the first clamping member 2 and the second clamping member 3, which can effectively simulate the stacked tabs on the battery cell, thereby avoiding the direct use of soldered battery cells for reliability verification, thus avoiding the loss of finished battery cells and reducing testing costs.

[0029] In one embodiment, the first clamping member 2 is provided with a first clamping surface 4, the second clamping member 3 is provided with a second clamping surface 5, and the stacked tab 21 is clamped between the first clamping surface 4 and the second clamping surface 5.

[0030] This application achieves surface contact by clamping the stacked tabs 21 through the first clamping surface 4 and the second clamping surface 5. Specifically, as shown... Figure 1 As shown, the first clamping member 2 is located directly above the second clamping member 3. A first clamping surface 4 is provided on the side of the first clamping member 2 closest to the second clamping member 3, that is, the bottom surface of the first clamping member 2 has the first clamping surface 4. A second clamping surface 5 is provided on the side of the second clamping member 3 closest to the first clamping member 2, that is, the top surface of the second clamping member 3 has the second clamping surface 5. The first clamping surface 4 and the second clamping surface 5 are arranged vertically opposite each other. When the first clamping member 2 and the second clamping member 3 cooperate, they clamp the stacked tabs 21. At this time, the stacked tab 21 is disposed between the first clamping surface 4 and the second clamping surface 5, and the first clamping surface 4 and the second clamping surface 5 are arranged parallel to each other so that when the first clamping surface 4 and the second clamping surface 5 clamp the stacked tab 21, the first clamping surface 4 is in surface contact with the top surface of the stacked tab 21, and the second clamping surface 5 is in surface contact with the bottom surface of the stacked tab 21, so as to ensure that the stacked tab 21 will not be deformed under the clamping of the first clamping member 2 and the second clamping member 3, which can effectively simulate the stacked tab on the battery cell.

[0031] In one embodiment, the tab clamping fixture further includes a sliding base 6 and a sliding part 7. The sliding base 6 is disposed on the fixture base 1, and the sliding part 7 is slidably disposed on the sliding base 6. The first clamping member 2 is disposed on the sliding part 7, and the sliding direction of the sliding part 7 is along the direction in which the first clamping surface 4 and the second clamping surface 5 are relatively close to or far away from each other.

[0032] The first clamping member 2 of this application is slidably mounted on the tooling base 1. Specifically, as shown... Figure 1 and Figure 2 As shown, this application also includes a sliding base 6 and a sliding part 7. The sliding base 6 is disposed on the tooling base 1, and the sliding part 7 is slidably disposed on the sliding base 6. Furthermore, the first clamping surface 4 and the second clamping surface 5 are arranged in parallel. In order to facilitate the placement of the stacked tabs 21 between the first clamping surface 4 and the second clamping surface 5, the first clamping surface 4 and the second clamping surface 5 can be relatively far apart or close together. Therefore, the first clamping member 2 is arranged on the sliding part 7, and the sliding direction of the sliding part 7 on the sliding base 6 is along the direction in which the first clamping surface 4 and the second clamping surface 5 are relatively far apart or close together. Preferably, the sliding direction of the sliding part 7 on the sliding base 6 is perpendicular to the first clamping surface 4. When the sliding part 7 slides on the sliding base 6 in a direction perpendicular to the first clamping surface 4, the first clamping surface 4 and the second clamping surface 5 are relatively close together or far apart. Therefore, the distance between the first clamping surface 4 and the second clamping surface 5 can be adjusted by the sliding part 7 to facilitate the clamping of stacked tabs of different thicknesses, thereby improving the versatility of the tab clamping fixture.

[0033] In one embodiment, the electrode clamping fixture further includes an adapter 8, one end of which is disposed on the sliding part 7, and the other end of which forms a hinge end 9, and the first clamping member 2 is hinged to the hinge end 9.

[0034] This application achieves the connection between the first clamping member 2 and the sliding part 7 through the adapter 8. Specifically, as shown... Figure 1 and Figure 2As shown, several sliding bases 6 and sliding parts 7 are provided. Preferably, two sliding bases 6 and two sliding parts 7 are provided. The sliding parts 7 correspond one-to-one with the sliding bases 6. The sliding parts 7 are slidably disposed on the corresponding sliding bases 6. The two sliding bases 6 are arranged opposite each other, and the two sliding parts 7 are spaced apart. Further, an adapter 8 is disposed on the two sliding parts 7. The adapter 8 is arranged in a horizontal direction, and one end of the adapter 8 is disposed between the two sliding parts 7. The other end of the adapter 8 forms a hinge end 9. The adapter 8 is hinged to the first clamping member 2 through the hinge end 9, so as to realize the rotation of the first clamping member 2 relative to the second clamping member 3, so as to realize the rotation of the first clamping surface 4 relative to the second clamping surface 5. This makes it convenient for the user to place the stacked tab 21 between the first clamping surface 4 and the second clamping surface 5, or to facilitate the user to remove the welded stacked tab 21 from between the first clamping surface 4 and the second clamping surface 5.

[0035] In one embodiment, the first clamping member 2 includes a first clamping end 10, a hinge portion 11 and a free end 12 arranged sequentially. The hinge portion 11 is hinged to the hinge end 9, and the first clamping surface 4 is disposed on the first clamping end 10.

[0036] This application achieves the hinge connection between the first clamping member 2 and the adapter 8 through the cooperation of the hinge part 11 and the hinge end 9. Specifically, as shown... Figure 2 As shown, the first clamping member 2 includes a first clamping end 10, a hinge portion 11, and a free end 12 arranged sequentially. The hinge portion 11 of the first clamping member 2 is hinged to the hinge end 9 of the adapter 8. Therefore, the first clamping end 10 and the free end 12 form a lever mechanism based on the hinge portion 11. By moving the free end 12, the first clamping end 10 can be rotated to facilitate the placement and clamping of the stacked tab 21. Furthermore, the first clamping surface 4 is disposed on the first clamping end 10. Therefore, by moving the free end 12, the first clamping surface 4 can be rotated relative to the second clamping surface 5 to facilitate the user placing the stacked tab 21 between the first clamping surface 4 and the second clamping surface 5, or to facilitate the user removing the soldered stacked tab 21 from between the first clamping surface 4 and the second clamping surface 5.

[0037] In one embodiment, the adapter 8 is provided with a first limiting part 13, which contacts the first clamping part 2 such that the first clamping surface 4 is parallel to the second clamping surface 5.

[0038] This application uses a first limiting part 13 to ensure that the first clamping surface 4 and the second clamping surface 5 are arranged parallel to each other. Specifically, as shown... Figure 2As shown, the hinge portion 11 of the first clamping member 2 of this application is hinged to the hinge end 9 of the adapter 8. A first limiting portion 13 is provided on the side of the hinge portion 11 near the first clamping end 10. The top surface of the first limiting portion 13 is parallel to the second clamping surface 5. When the first clamping surface 4 on the first clamping member 2 contacts the top surface of the first limiting portion 13, the first clamping surface 4 on the first clamping member 2 is parallel to the second clamping surface 5 by the limiting of the first limiting portion 13. This ensures that when the stacked tab 21 is clamped between the first clamping surface 4 and the second clamping surface 5, the stacked tab 21 is in surface contact with both the first clamping surface 4 and the second clamping surface 5, so as to ensure that the stacked tab 21 will not deform under the clamping of the first clamping member 2 and the second clamping member 3, and can effectively simulate the stacked tab on the battery cell.

[0039] In one embodiment, the tab clamping fixture further includes an adjusting member 15, one end of which is disposed on the fixture base 1, and the other end of which is disposed on the sliding part 7 and / or the adapter 8.

[0040] This application adjusts the distance between the first clamping surface 4 and the second clamping surface 5 by adjusting the distance between the sliding part 7 and the tooling base 1, so as to clamp stacked tabs of different thicknesses. Since the sliding part 7 is slidably disposed on the sliding base 6 and the adapter 8 is disposed on the sliding part 7, in order to adjust the distance between the first clamping surface 4 and the second clamping surface 5 by adjusting the adjusting part 15, one end of the adjusting part 15 needs to be connected to the tooling base 1, and the other end of the adjusting part 15 needs to be connected to the sliding part 7 and / or the adapter 8. That is, the other end of the adjusting part 15 is connected to the sliding part 7, or the other end of the adjusting part 15 is connected to the adapter 8, or the other end of the adjusting part 15 is connected to both the sliding part 7 and the adapter 8. Preferably, the other end of the adjusting member 15 is connected to the adapter 8. Therefore, by adjusting the position of the adapter 8 along its sliding direction by adjusting the adjusting member 15, the distance between the first clamping surface 4 on the first clamping member 2 and the second clamping surface 5 on the second clamping member 3 can be adjusted. Specifically, as shown... Figure 4As shown, the adjusting member 15 includes an operating part 16, a second limiting part 17, and a threaded part 18 arranged sequentially. A limiting plate 19 is provided on the tooling base 1, and a limiting groove 20 is formed between the limiting plate 19 and the tooling base 1. The second limiting part 17 of the adjusting member 15 is rotatably disposed in the limiting groove 20, and the second limiting part 17 has only one degree of rotational freedom about its axis in the limiting groove 20. The adapter 8 is provided with an internal thread, and the threaded part 18 on the adjusting member 15 cooperates with the internal thread on the adapter 8. The adapter 8 has only one degree of sliding freedom along its sliding direction, so as to adjust the screw... The rotational motion of the threaded part 18 is converted into the linear motion of the adapter 8 in the vertical direction. The operating part 16 is the part that the user rotates. The user rotates the operating part 16 with a tool, and the operating part 16 drives the threaded part 18 to rotate. The threaded part 18 and the internal thread on the adapter 8 cooperate to convert the rotational motion of the threaded part 18 into the linear motion of the adapter 8 in the vertical direction. This allows the adapter 8 to drive the first clamping part 2 to make a linear motion in the vertical direction, thereby adjusting the distance between the first clamping surface 4 and the second clamping surface 5 to accommodate stacked tabs of different thicknesses and improve the versatility of the tab clamping fixture.

[0041] In one embodiment, the electrode clamping fixture further includes an elastic element 14, which is disposed between the free end 12 and the adapter 8, and the elastic element 14 is a compression spring; or the elastic element 14 is disposed between the first clamping end 10 and the adapter 8, and the elastic element 14 is a tension spring.

[0042] This application applies clamping pressure between the first clamping member 2 and the second clamping member 3 through the elastic element 14. Specifically, when the stacked tab 21 is clamped by the first clamping surface 4 on the first clamping member 2 and the second clamping surface 5 on the second clamping member 3, a certain pressure needs to be applied to the first clamping member 2 and the second clamping member 3, so that the first clamping surface 4 and the second clamping surface 5 apply a certain pressure to the stacked tab 21, so that the first clamping surface 4 and the second clamping surface 5 can effectively clamp the stacked tab 21. This application uses the elastic element 14 to apply the clamping pressure between the first clamping surface 4 and the second clamping surface 5. Further, the elastic element 14 is a spring, which has two working states: one is a spring state, that is, the spring is a compression spring; the other is a tension state, that is, the spring is a tension spring. The position of the elastic element 14 can be arranged according to the working state of the spring. For example... Figure 5As shown, the elastic element 14 is disposed between the free end 12 of the first clamping member 2 and the adapter 8. The elastic element 14 is a compression spring. Under the spring force, the free end 12 of the first clamping member 2 is always away from the tooling base 1 in its free state. Therefore, under the action of the lever, the first clamping end 10 of the first clamping member 2 is always in a state of pressing against the stacked tabs 21. The pressure between the first clamping surface 4 on the first clamping end 10 and the second clamping surface 5 on the second clamping member 3 is designed through the elastic force of the elastic element 14 and the lever arm. Figure 6 As shown, the elastic element 14 is disposed between the first clamping end 10 of the first clamping member 2 and the adapter 8. At this time, the elastic element 14 is a tension spring. Under the tension of the tension spring, the first clamping end 10 of the first clamping member 2 is always in the state of pressing the stacked tab 21. The pressure between the first clamping surface 4 on the first clamping end 10 and the second clamping surface 5 on the second clamping member 3 is designed by the elastic force of the elastic element 14 and the lever arm.

[0043] In one embodiment, the elastic element 14 is detachably disposed between the first clamping member 2 and the adapter 8. The elastic element 14 has different specifications, and the elastic elements 14 of different specifications have different tensile or compressive forces.

[0044] This application utilizes a detachable elastic element 14 to adjust the clamping pressure of the stacked tabs 21. The elastic element 14 has different specifications, each with different tension or compression forces. The elastic element 14 is detachably disposed between the first clamping member 2 and the adapter 8. The elastic element 14 is either a tension spring or a compression spring. Therefore, by replacing the compression spring with a different pressure or the tension spring with a different tension, the pressure between the first clamping surface 4 and the second clamping surface 5 can be adjusted, thereby regulating the contact pressure between the first clamping surface 4, the stacked tabs 21, and the second clamping surface 5.

[0045] In one embodiment, the second clamping member 3 is detachably mounted on the tooling base 1. The second clamping member 3 has different specifications, and the first clamping member 2 of different specifications has different thicknesses.

[0046] This application further improves the versatility of the tab clamping fixture by using a second clamping member 3 of varying thicknesses. Specifically, such as... Figure 2As shown, the second clamping member 3 is rectangular and mounted on the tooling base 1, with the second clamping surface 5 positioned at its top. The second clamping members 3 come in different specifications and thicknesses. The tooling base 1 has a mounting groove 22, and the second clamping members 3 of different specifications are detachably mounted within this groove. When the sliding part 7 is fixed relative to the tooling base 1 (i.e., when the first clamping surface 4 on the first clamping member 2 is fixed), different thicknesses of the second clamping members 3 are used on the tooling base 1. The distance between the second clamping surface 5 and the first clamping surface 4 on each second clamping member 3 is different, thus accommodating stacked tabs of different thicknesses. Furthermore, when the sliding part 7 is positioned at the top of the sliding base 6 using the adjusting member 15, a thinner second clamping member 3 can be used to extend the distance between the first clamping surface 4 and the second clamping surface 5, further accommodating thicker stacked tabs and improving the versatility of the tab clamping tooling.

[0047] In one embodiment, the first clamping surface 4 and the second clamping surface 5 have a first width, and the stacked tab 21 has a second width, wherein the first width is greater than the second width.

[0048] This application improves the clamping effect of the first clamping surface 4 and the second clamping surface 5 on the stacked tabs 21 by matching the width of the clamping surface with the width of the stacked tabs 21. Specifically, as shown... Figure 7 As shown, the first clamping surface 4 and the second clamping surface 5 have the same width. The first clamping surface 4 and the second clamping surface 5 are arranged parallel to each other. The direction perpendicular to the first clamping surface 4 is the first direction. Along the first direction, the ends of the first clamping surface 4 and the second clamping surface 5 away from the sliding base 6 are aligned vertically and horizontally and along the width direction. Furthermore, the width of the stacked tab 21 is the second width W2, and the width of the first clamping surface 4 and the second clamping surface 5 is the first width W1. The first width W1 is greater than the second width W2, so that when the first clamping surface 4 and the second clamping surface 5 clamp the stacked tab 21, the first clamping surface 4 and the second clamping surface 5 can cover the width of the stacked tab 21, so that the portion of the stacked tab 21 along the width direction is completely clamped by the first clamping surface 4 and the second clamping surface 5, thereby improving the clamping reliability of the first clamping surface 4 and the second clamping surface 5 on the stacked tab 21 and effectively simulating the stacked tab on the battery cell.

[0049] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
