[0045] The utility model is described in detail below in conjunction with the accompanying drawings.

[0046] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0047] In the battery production process, the workpiece is often positioned on the tooling, and then the workpiece and other parts are glued, welded, and other operations are performed. However, the structure of the tooling is fixed, and different tooling needs to be configured for workpieces of different specifications. This will increase the production and manufacturing costs of the tooling on the one hand; on the other hand, as the battery production specifications change, the tooling needs to be replaced, which reduces production efficiency. For this reason, the technical solution of this application is generated, and the following is combined with Figure 1 to Figure 4 To elaborate.

[0048] Example 1

[0049] This embodiment provides a tooling for a workpiece 1, the tooling includes a base plate 40, a first stopper assembly 10 and a second stopper assembly 20. The base plate 40 is the installation base of the present application, and the base plate 40 can be used to carry the workpiece 1. At the same time, other parts on the tooling can be arranged on the base plate 40. Specifically, the first stopper assembly 10 and the second stopper assembly 20 can be arranged on the same side of the base plate 40, and the second stopper assembly 20 and the first stopper assembly 10 are between the workpiece clamping area 401, and the workpiece clamping area 401 is used to place the workpiece 1. The second stopper assembly 20 and the first stopper assembly 10 cooperate with each other to clamp and fix the workpiece 1.

[0050] At least one of the first stopper assembly 10 and the second stopper assembly 20 is adsorbed and connected to the substrate 40, and the position at which at least one of the first stopper assembly 10 and the second stopper assembly 20 is adsorbed and connected to the substrate 40 can be adjusted. For example, the first stopper assembly 10 is adsorbed and connected to the substrate 40, and the first stopper assembly 10 can be adjusted to the connection position on the substrate 40 when the adsorption is released or the adsorption state is maintained, and the second stopper assembly 20 is fixed to the substrate 40, or the second stopper assembly 20 is adsorbed and connected to the substrate 40, and the second stopper assembly 20 can be adjusted to the connection position on the substrate 40 when the adsorption is released or the adsorption state is maintained, and the first stopper assembly 10 is fixed to the substrate 40, or both the second stopper assembly 20 and the first stopper assembly 10 are adsorbed and connected to the substrate 40, and both can be adjusted to the connection position on the substrate 40 when the adsorption is released or the adsorption state is maintained. The adsorption connection here can be understood as magnetic adsorption, vacuum adsorption, etc.

[0051] In this way, the position where at least one of the first stopper assembly 10 and the second stopper assembly 20 is adsorbed and connected to the substrate 40 can be adjusted according to the specifications of the clamped workpiece 1, thereby adjusting the size of the workpiece clamping area 401 to fit the workpiece 1. In this way, in the first aspect, the tooling of the present application can fit a variety of workpieces 1 of different specifications, without the need to specially match the corresponding tooling for each specification of the workpiece 1, thereby reducing the production cost of the tooling; in the second aspect, it avoids the need to change the tooling when the battery production specifications change, thereby improving production efficiency.

[0052] The following takes the first stopper assembly 10 being adsorbed and connected to the substrate 40 as an example to further introduce the tooling of the present application:

[0053] The first stopper assembly 10 may include a first stopper block 11 and an adsorbent 12. The adsorbent 12 is mounted on the first stopper block 11 and adsorbs the connected substrate 40. The first stopper block 11 and the second stopper assembly 20 are provided with a workpiece clamping area 401. In this way, the various components of the first stopper assembly 10 are divided into different parts to make the use of the first stopper assembly 10 more reasonable. For example, the adsorption force generated by the adsorbent 12 can be adjusted by controlling the size of the adsorbent 12. Alternatively, the first stopper block 11 may be made of a non-magnetic non-metallic material. For example, the first stopper block 11 may be made of polyformaldehyde (POM), which is a tough and elastic material that has good creep resistance, geometric stability and impact resistance even at low temperatures. In this way, when the first stopper block 11 is used to clamp the workpiece 1, the first stopper block 11 may be prevented from deforming after long-term use to affect the clamping accuracy, and the workpiece 1 may be prevented from being damaged.

[0054] Optionally, at least two first stop blocks 11 may be provided to stop different positions of the workpiece 1, thereby better fixing the workpiece 1. However, the present application may only provide one first stop assembly 10, and a notch 111 may be provided in the first stop block 11, and the notch 111 may face the second stop assembly 20 so that the notch 111 is used to abut against the workpiece 1, so that the shape of the notch 111 is used to achieve contour clamping and positioning of the workpiece 1, without providing at least two first stop assemblies 10, thereby reducing the amount of materials while ensuring the clamping effect of the workpiece 1.

[0055] Optionally, the workpiece 1 may be a cover plate of a square battery. Specifically, the workpiece 1 may include first side surfaces 1a arranged opposite to each other along its length direction, and second side surfaces 1b arranged opposite to each other along its width direction, with an edge 1c formed between adjacent first side surfaces 1a and second side surfaces 1b.

[0056] The first stop block 11 can be set as a wedge block. Specifically, the first stop block 11 can also be provided with an avoidance groove 112, and the notch 111 is provided with a first abutting surface 1111 for abutting against the first side surface 1a, and a second abutting surface 1112 for abutting against the second side surface 1b, and the first abutting surface 1111 and the second abutting surface 1112 can form a 90° angle. In this way, the notch 111 can achieve abutment against different sides of the workpiece 1, and then achieve the limitation of the workpiece 1 along its length direction and width direction, so as to ensure the clamping and fixing effect of the workpiece 1.

[0057] The avoidance groove 112 is located at the intersection of the first abutment surface 1111 and the second abutment surface 1112, and the avoidance groove 112 is used to avoid the edge 1c. In this way, the root of the notch 111 is cleaned by the arrangement of the avoidance groove 112, so as to prevent the root of the notch 111 from squeezing the edge 1c, thereby ensuring sufficient contact between the first abutment surface 1111 and the first side surface 1a, and between the second abutment surface 1112 and the second side surface 1b, further improving the clamping and fixing effect of the tooling of the present application.

[0058] Optionally, at least two adsorption members 12 can be provided, for example, two adsorption members 12 are provided, symmetrically on both sides of the notch 111, so that the first stop component 10 will have two adsorption points to ensure the connection stability between the substrate 40 and the first stop component 10, thereby ensuring the clamping effect of the first stop component 10 on the workpiece 1.

[0059] Optionally, the first stop block 11 can be provided with a receiving hole 113, and at least a portion of the adsorption component 12 is disposed in the receiving hole 113, for example, the adsorption component 12 is entirely disposed in the receiving hole 113, or a portion of the adsorption component 12 is disposed in the receiving hole 113, and the other portion extends out of the receiving hole 113 to adsorb and connect the substrate 40. In this way, the connection stability between the first stop block 11 and the adsorption component 12 can be better guaranteed.

[0060] Optionally, for the connection between the first stop block 11 and the adsorption member 12, the adsorption member 12 can be embedded in the receiving hole 113 and have an interference fit with the receiving hole 113 to further improve the connection stability between the first stop block 11 and the adsorption member 12. In this embodiment, it can be achieved by bolting, as follows:

[0061] The first stop block 11 may also be provided with a threaded hole 114, the receiving hole 113 and the threaded hole 114 are sequentially connected in a direction away from the substrate 40, and the adsorbent 12 is sequentially provided with a countersunk hole 121 and a bolt through hole 122 in a direction away from the substrate 40. The first stop assembly 10 also includes a connecting bolt 13, the screw of the connecting bolt 13 passes through the bolt through hole 122 and is threadedly connected to the threaded hole 114, the bolt head of the connecting bolt 13 is located in the countersunk hole 121 and abuts against the bottom surface of the countersunk hole 121. In this way, it is possible to ensure a firm connection between the first stop block 11 and the adsorbent 12, and it is also possible to more conveniently implement maintenance and replacement of the adsorbent 12.

[0062] Optionally, magnetic adsorption can be performed between the first stopper assembly 10 and the substrate 40. Specifically, the substrate 40 is provided with a magnetic metal, for example, the substrate 40 is made of 45# steel, and the substrate 40 can be placed on a magnetic workbench to remain fixed. The adsorption member 12 can be a magnetic iron buckle, and the adsorption member 12 is magnetically connected to the substrate 40. The magnetic connection method facilitates the position adjustment operation of the first stopper assembly 10. For example, the first stopper assembly 10 can maintain an adsorption state and slide on the surface of the substrate 40 until it abuts against the workpiece 1, or the first stopper assembly 10 can be separated from the current connection position on the substrate 40 and adjusted to another connection position on the adsorption substrate 40 until it abuts against the workpiece 1, so as to facilitate the clamping of the workpiece 1.

[0063] In some other optional embodiments, vacuum adsorption can be performed between the first stop component 10 and the substrate 40, such as providing a suction cup on the adsorption member 12 to adsorb the substrate 40, or providing a plurality of vacuum adsorption holes on the substrate 40 to adsorb the first stop component 10, which will not be described in detail here.

[0064] Optionally, the surface of the substrate 40 used to place the workpiece 1 has a flatness of ≤0.1 mm to ensure that the workpiece 1 is placed stably and prevent the workpiece 1 from warping or being placed unsteadily when clamping or gluing the workpiece 1 with other parts, thereby ensuring processing accuracy. Furthermore, the surface of the substrate 40 can be wrapped with a protective layer, such as a layer of Teflon tape, to prevent the surface of the substrate 40 from being worn during use, which may cause the flatness of the substrate 40 to exceed the tolerance.

[0065] Example 2

[0066] Based on Example 1, the tooling provided in this example is as follows:

[0067] In this embodiment, the structure of the second stopper assembly 20 can be the same as that of the first stopper assembly 10, for example, both are wedge-shaped block structures that are adsorbed and connected to the substrate 40, and the connection position can be changed arbitrarily. In this application, the second stopper assembly 20 can be set to include a first stopper bar 21 and a second stopper bar 22, which are set on the same side of the substrate 40, and the extension directions of the first stopper bar 21 and the second stopper bar 22 are different, for example, perpendicular to each other, wherein the first stopper bar 21 is used to abut against the first side surface 1a of the workpiece 1, and the second stopper bar 22 is used to abut against the second side surface 1b of the workpiece 1; the first stopper bar 21, the second stopper bar 22 and the first stopper assembly 10 form a workpiece clamping area 401. The positions of the first stopper bar 21 and the second stopper bar 22 are fixed, for example, the first stopper bar 21 and the second stopper bar 22 can be fixedly connected to the substrate 40 by tie bolts, that is, when adjusting the size of the workpiece clamping area 401, only the connection position of the first stopper assembly 10 on the substrate 40 is adjusted, which reduces the difficulty of operating the tooling of this application.

[0068] Optionally, an avoidance gap 23 can be reserved between the first baffle 21 and the second baffle 22, and the avoidance gap 23 is used to avoid the edge 1c of the workpiece, thereby ensuring sufficient contact between the first baffle 21 and the first side surface 1a, and between the second baffle 22 and the second side surface 1b, further improving the clamping and fixing effect of the tooling.

[0069] Example 3

[0070] Based on Example 2, this example further designs other structures of the tooling, as follows:

[0071] Optionally, the base plate 40 may be provided with at least one of a first mounting groove 41 and a second mounting groove (not shown in the figure), for example, the base plate 40 is provided with only the first mounting groove 41, or the base plate 40 is provided with only the second mounting groove, or the first mounting groove 41 and the second mounting groove are both provided on the base plate 40. The first stop bar 21 is clamped in the first mounting groove 41, and the second stop bar 22 is clamped in the second mounting groove, so that the first stop bar 21 and the second stop bar 22 are conveniently installed.

[0072] Optionally, the first mounting groove 41 is slidably matched with the second stop bar 22, and the first mounting groove 41 has an opening located on the side of the substrate 40, and the second stop bar 22 can be disassembled and assembled on the substrate 40 in a sliding manner, further improving the convenience of disassembly and assembly. Similarly, the second mounting groove is slidably matched with the first stop bar 21, and the second mounting groove has an opening located on the side of the substrate 40, so as to improve the convenience of disassembly and assembly of the first stop bar 21, which will not be described in detail here.

[0073] Optionally, the tooling may further include a third stop assembly 30, and the third stop assembly 30 is disposed on a side of at least one of the first stop bar 21 and the second stop bar 22 that is away from the workpiece clamping area 401. For example, the third stop assembly 30 is disposed on a side of the first stop bar 21 that is away from the workpiece clamping area 401, or the third stop assembly 30 is disposed on a side of the second stop bar 22 that is away from the workpiece clamping area 401, or both the side of the first stop bar 21 that is away from the workpiece clamping area 401 and the side of the second stop bar 22 that is away from the workpiece clamping area 401 are provided with the third stop assembly 30.

[0074] The first stop bar 21 or the second stop bar 22 adjacent to the third stop assembly 30 is detachably connected to the base plate 40, for example, by bolting, clamping, etc. The height of the first stop bar 21 or the second stop bar 22 adjacent to the third stop assembly 30 is less than the height of the third stop assembly 30, and the height direction is perpendicular to the base plate 40.

[0075] Taking the example of the third stop assembly 30 being arranged on the side of the second stop bar 22 away from the workpiece clamping area 401, when it is necessary to position some workpieces 1 with larger thickness, the second stop bar 22 can be removed so that the third stop assembly 30 can cooperate with the first stop bar 21 to complete the clamping and positioning of the workpiece 1 with larger thickness. When positioning the workpiece 1 with smaller thickness, the second stop bar 22 can be installed again so that the second stop bar 22 can cooperate with the first stop bar 21 to complete the clamping and positioning of the workpiece 1 with smaller thickness, thereby further improving the compatibility of the tooling of the present application.

[0076] Optionally, the third stop assembly 30 may be formed by stacking at least two third stop bars 31 together in the height direction, so as to control and adjust the height of the third stop assembly 30 .

[0077] Optionally, the tooling may further include a mounting bar 50. In this embodiment, the third stop assembly 30 may be disposed on the side of the second stop bar 22 away from the workpiece clamping area 401, and the mounting bar 50 is connected to the substrate 40. The first stop bar 21 may be connected to the side of the mounting bar 50 facing the workpiece clamping area 401. The mounting bar 50 serves as the mounting basis of the first stop bar 21 to improve the connection stability of the first stop bar 21. At the same time, the mounting bar 50 can realize the connection between the tooling of the present application and other external components to ensure the position stability of the tooling of the present application when in use.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
