[0038] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] The tooling 100 for the blade-type battery cell 200 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 4As shown, the tooling 100 for the blade-type battery cell 200 according to an embodiment of the present invention includes: a base 1, a bracket assembly 2, a baffle 3, a mounting plate 4 and a movable plate 5.

[0041] Specifically, the bracket assembly 2 is mounted on one side of the base 1, the baffle 3 and the mounting plate 4 are respectively mounted on the bracket assembly 2, and the movable plate 5 is movably mounted on the mounting plate 4 and spaced apart from and opposite to the baffle 3. A receiving space 62 having an opening 61 is enclosed between the base 1, bracket assembly 2, baffle 3, and mounting plate 4. The opening 61 is formed by the baffle 3, mounting plate 4, and movable plate 5, and the size of the opening 61 is adjusted by the spacing between the movable plate 5 and the baffle 3.

[0042] In other words, the tooling 100 for the blade-type battery cell 200 according to the embodiment of the present invention is mainly composed of a base 1, a bracket assembly 2, a baffle 3, a mounting plate 4, and a movable plate 5. The bracket assembly 2 is mounted on one side of the base 1, for example, the lower end of the bracket assembly 2 is mounted on the upper surface of the base 1. The baffle 3 and the mounting plate 4 can be mounted on the bracket assembly 2, for example, the baffle 3 and the mounting plate 4 are mounted on the upper end of the bracket assembly 2. Among them, the bracket assembly 2 can be made of aluminum, for example, including four aluminum cylinders. The baffle 3 and the mounting plate 4 can also be made of aluminum plates to reduce weight.

[0043] Among them, a receiving space 62 with an opening 61 is enclosed between the base 1, the bracket assembly 2, the baffle 3 and the mounting plate 4. For example, the opening 61 formed by the baffle 3, the mounting plate 4 and the movable plate 5 is set upward. When in use, the blade-type battery cell 200 is placed downward through the opening 61 until the lower end of the blade-type battery cell 200 rests on the base 1.

[0044] It can be understood that in this embodiment, the bracket assembly 2 can not only play the role of forming a receiving space 62 together with the baffle 3, the base 1, etc., but also provide an installation area for the baffle 3 and the mounting plate 4, and can also realize a spacing space between the baffle 3, the mounting plate 4 and the base 1, so as to facilitate the accommodation of the longer blade-type battery cells 200.

[0045] In addition, the opening 61 is formed by the baffle 3, the mounting plate 4 and the movable plate 5, and the size of the opening 61 is adjusted by the distance between the movable plate 5 and the baffle 3. That is, the baffle 3 and the movable plate 5 are relatively movable. By driving the movable plate 5 toward the baffle 3, the width of the opening 61 can be reduced, and by driving the movable plate 5 away from the baffle 3, the width of the opening 61 can be expanded. Furthermore, the opening 61 can be first expanded to a size larger than the blade-type battery cell 200, and then one end of the blade-type battery cell 200 can be taken out or placed into the receiving space 62. When the opening 61 is reduced to the point where the baffle 3 and the movable plate 5 respectively and simultaneously abut the surface of the blade-type battery cell 200, the freedom of the blade-type battery cell 200 in one direction is limited by the baffle 3 and the movable plate 5, and the freedom of the blade-type battery cell 200 in another direction can also be limited by the mounting plate 4, and the freedom of the blade-type battery cell 200 in another direction can also be limited by the base 1, thereby achieving the limitation of the blade-type battery cell 200 and facilitating the processing of the blade-type battery cell 200.

[0046] Therefore, according to the embodiment of the utility model, the tooling 100 for the blade-type battery cell 200 adopts a combination of a base 1, a bracket assembly 2, a baffle 3, a mounting plate 4 and a movable plate 5, which can achieve the limitation of the blade-type battery cell 200 with a longer length, thereby facilitating the processing of the blade-type battery cell 200.

[0047] Optionally, both the baffle 3 and the movable plate 5 use large surfaces with larger areas to contact the battery cell 200, which can expand the contact area, avoid deformation of the battery cell 200 during squeezing, avoid indentations, and improve the fixing effect of the battery cell 200.

[0048] According to one embodiment of the present invention, the tooling 100 for blade-type battery cells 200 further includes a driver 7 mounted on the mounting plate 4 and connected to the movable plate 5 to adjust the distance between the movable plate 5 and the baffle 3. In this embodiment, mounting the driver 7 on the mounting plate 4 facilitates implementation, operation, and storage. Using the driver 7 to drive the movable plate 5 relative to the baffle 3 improves operational convenience compared to manually pressing the movable plate 5, facilitating application of force to the movable plate 5.

[0049] In some specific embodiments of the present invention, the driving member 7 includes: a connecting plate 71 and a movable rod 72. The connecting plate 71 is connected to the mounting plate 4. The connecting plate 71 has a threaded hole. One end of the movable rod 72 passes through the threaded hole and is connected to the movable plate 5, and the other end of the movable rod 72 extends out of the threaded hole. In other words, the movable rod 72 can be threadedly connected to the threaded hole. During operation, the movable rod 72 can be rotated to move the movable rod 72, thereby driving the movable plate 5 forward or backward. Moreover, due to the use of a threaded connection method, there is no need to continuously apply force to the movable rod 72. The movable rod 72 can also be stopped at the position where the force was last applied, and there will be no backward movement. For example, when the movable rod 72 is rotated to the movable plate 5 and the baffle 3 to clamp the battery cell 200, the battery cell 200 will not be offset, and the battery cell 200 will not be easily indented. The pressure it is subjected to can be 5 to 10 kg.

[0050] According to one embodiment of the present invention, the other end of the movable rod 72 is connected to the holding portion 73, and there is an angle between the holding portion 73 and the movable rod 72. For example, the holding portion 73 extends in the left-right direction, and the movable rod 72 extends in the front-back direction, and the two are perpendicular to each other. In this embodiment, by adopting the holding portion 73 that is tilted between the movable rod 72, it is convenient for the operator to hold it. It can be understood that the angle here refers to an angle that is not 0° or 180°. When in use, the battery cell 200 can be placed on the tooling 100, and the holding portion 73 can be rotated so that the movable plate 5 is pushed forward, so that the battery cell 200 is subjected to an extrusion force in the front-back direction, thereby achieving the effect of fixing the battery cell 200. Optionally, the holding portion 73 and the movable rod 72 are connected by electric welding to improve the firmness of the connection.

[0051] In some specific embodiments of the present invention, a T-shaped first groove 51 is provided on the movable plate 5, and one end of the movable rod 72 is T-shaped and is stuck in the first groove 51. For example, the front side of the movable plate 5 is provided with a T-shaped first groove 51, and the first groove 51 includes a horizontal groove and a vertical groove, forming a T-shaped groove. The horizontal groove and the vertical groove are respectively connected to the upper space. The horizontal groove is located in front of the vertical groove. The horizontal groove extends in the left-right direction, and the vertical groove extends in the front-back direction. The vertical groove connects to the rear space. The T-shaped portion at the front end of the movable rod 72 can be installed from the top to the bottom into the T-shaped groove, and the movable rod 72 can extend backward from the T-shaped groove through the vertical groove. In this embodiment, by adopting the T-shaped first groove 51 on the movable plate 5 and the T-shaped end of the movable rod 72, the connection strength between the movable plate 5 and the movable rod 72 can be improved, the contact area between the movable plate 5 and the movable rod 72 can be expanded, and the uniformity of force application can be improved.

[0052] According to one embodiment of the present invention, a second groove 11 is provided on the base 1 to accommodate the end of the battery cell 200, which facilitates multi-directional positioning of the battery cell 200. In addition, the second groove 11 provided on the base 1 can serve as a clearance space for the connecting piece at the lower end of the battery cell 200. For example, the depth of the second groove 11 should be higher than the height from the connecting piece to the battery casing after the connecting piece of the battery cell 200 is welded to the pole, and the depth is generally more than 10 mm. In addition, the second groove 11 can ensure that the battery cell 200 is supported by the support force from the bottom and the support force of the movable plate 5 during welding, thereby playing a reinforcing role.

[0053] In some specific embodiments of the present invention, two mounting plates 4 are provided, one at each end of the baffle 3. For example, one mounting plate 4 is located at the left end of the baffle 3, and the other at the right end. In this embodiment, the use of two mounting plates 4 not only improves structural stability but also allows for multi-directional positioning of the battery cells 200. Furthermore, the simultaneous connection of the two mounting plates 4 to a single connecting plate 71 enhances the installation stability of the connecting plate 71 and prevents deformation or displacement of the connecting plate 71 when the movable rod 72 moves.

[0054] According to one embodiment of the present invention, the bracket assembly 2 includes four brackets 21, wherein one end of two brackets 21 is respectively connected to the base 1, and the other end is respectively connected to the baffle 3; one end of the other two brackets 21 is connected to the base 1, and the other end is connected to the mounting plate 4. For example, the two brackets 21 on the front side are spaced apart and distributed along the left and right directions, and the two brackets 21 on the rear side are also spaced apart and distributed along the left and right directions, and each bracket 21 extends along the up and down directions. In this embodiment, by adopting four brackets 21, the stability of the overall structure can be improved, and it is conducive to forming a square receiving space 62, which is convenient for accommodating the square blade battery cells 200. Optionally, the baffle 3 and the mounting plate 4 are integrally formed parts, which are convenient for processing and installation.

[0055] According to one embodiment of the present invention, a slide rail 8 is provided on the mounting plate 4, and the movable panel 5 is mounted to the mounting plate 4 via the slide rail 8. For example, the mounting plate 4 is provided with a slide rail 8 extending in the front-to-back direction. In this embodiment, the provision of the slide rail 8 provides advantages such as guiding the movement of the movable panel 5 and improving the smoothness of the movement. The slide rail 8 also balances the forces acting on the movable panel 5.

[0056] In some specific embodiments of the present invention, the length of the bracket 21 is adjustable, or the bracket 21 is detachable from the base 1, the baffle 3, and the mounting plate 4. By adjusting the height of the receiving space 62, it can be adapted to battery cells 2 of different lengths. For example, it can be adapted to the welding of the pole connecting pieces 201 of various blade battery cells 200, which can improve the connection stability of the welding points and thus improve the accuracy of the test. For another example, the bracket 21 uses a screw, and the screw can be switched in length. The screw for switching the length can have a male thread at the head and a female thread at the tail, which is conducive to compatibility with battery cells 200 of different lengths. In addition, 304 stainless steel screws can be used between the bracket 21 and the base 1, the baffle 3, and the mounting plate 4, which has strong versatility.

[0057] Optionally, in order to prevent the tool 100 from tipping over during pole welding, a counterweight plate may be added under the base 1 to solve the problem of the tool tipping over.

[0058] The present invention also discloses a device for processing blade-type batteries, comprising: a tool 100 and a processing assembly, wherein the tool 100 is used to fix the battery cell 200, and the tool 100 is the tool 100 according to any of the above-mentioned embodiments, and the processing assembly is used to process the battery cell 200 fixed to the tool 100. For example, the processing assembly is a laser welding machine, and the tool 100 and the battery cell 200 can be placed on the operating table of the laser welding machine to weld the pole connecting piece 201. After welding one end of the battery cell 200, the gripping portion 73 is rotated to release the squeezing force, and the positive and negative poles of the battery cell 200 are swapped, and then the pole connecting piece 201 on the other side is welded. In addition, since the tool 100 for the blade-type battery cell 200 according to the embodiment of the present invention can limit the blade-type battery cell 200 with a longer length, the processing device for the blade-type battery cell according to the embodiment of the present invention can improve the processing efficiency and processing effect of the blade-type battery cell, which will not be described in detail here.
