Description

Technical Field

[0001] The utility model belongs to the technical field of battery coding, and specifically relates to an anti-fooling tooling for lithium battery coding. Background Art

[0002] During the processing of battery covers, a coding operation is required. The coding operation can store key information (such as incoming material information, production process, product batch, manufacturer, and date) in a two-dimensional code and mark it on the battery shell. This helps to trace the production information of the product in subsequent production, transportation, sales, and other links, ensuring the controllability and traceability of product quality. To improve the accuracy of the coding position, a coding tooling is needed to limit the position of the battery cover.

[0003] Existing coding toolings generally only have a simple limiting effect on the cover top of the cover through a groove-shaped structure. However, in the actual processing process, due to factors such as employees' incorrect operations or product shapes, the coding position often shifts, resulting in defective products and economic losses. Therefore, it is necessary to propose an anti-fooling tooling for lithium battery coding to solve the above problems. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model proposes an anti-fooling tooling for lithium battery coding, which solves the problem that the existing coding tooling is prone to coding position deviation and defective products due to factors such as employees' incorrect operations or product shapes.

[0005] To achieve the above object, according to an embodiment of the first aspect of the utility model, an anti-fooling tooling for lithium battery coding is proposed, which includes a tooling substrate. Positioning members for limiting the position of the battery cover are symmetrically arranged on the top of the tooling substrate. The positioning members include a plurality of uniformly distributed limiting grooves and anti-fooling step grooves, and the limiting grooves and anti-fooling step grooves are distributed along the length direction of the tooling substrate. The limiting grooves and anti-fooling step grooves are both opened on the top of the tooling substrate. One end of the limiting groove close to the length side of the tooling substrate is open. The anti-fooling step groove is distributed circumferentially along the notch of the limiting groove, and the anti-fooling step groove is communicated with the limiting groove. An anti-reverse column is installed at the bottom of the limiting groove.

[0006] As a further technical solution of the utility model, a cover plate is attached to the top of the tooling substrate. A plurality of hollow parts corresponding to the limiting grooves are penetrated through the cover plate, and the hollow parts are located directly above the limiting grooves.

[0007] As a further technical solution of the utility model, symmetrically arranged positioning holes are penetrated through the cover plate. An installation groove corresponding to the positioning holes is opened on the top of the tooling substrate, and a positioning pin matching the positioning holes is installed in the installation groove.

[0008] As a further technical solution of the present utility model, upper handles are installed at the centers of the side walls at both ends of the cover plate, and lower handles are installed at the centers of the side walls at both ends of the tooling substrate.

[0009] As a further technical solution of the present utility model, the anti-reverse column includes a cylindrical protrusion.

[0010] As a further technical solution of the present utility model, lower grooves are symmetrically formed at the bottom of the tooling substrate, and the lower grooves are used to dock with the limit pins on the coding carrier platform.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the placement direction of the battery cover plate to be coded is conveniently limited by the limit groove on the working substrate, and the docking part of the battery cover plate is conveniently accommodated and limited in cooperation with the anti-fooling step groove. By using the anti-reverse column at the bottom of the limit groove, when the battery cover plate is in the wrong up-down direction, the anti-reverse column can jack it up, so that the battery cover plate cannot be fitted into the limit groove, thereby avoiding the battery cover plate being installed in reverse.

[0018] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Such asFigures 1-4 As shown in the figure, a foolproof tooling for lithium battery coding includes a tooling substrate 1. Lower handles 9 are installed at the centers of the side walls at both ends of the tooling substrate 1, which facilitates personnel to pick up the tooling substrate 1. Lower grooves 10 are symmetrically opened at the bottom of the tooling substrate 1. The lower grooves 10 are used to dock with the limit pins on the coding carrier. In this embodiment, limit pins with fixed positions are installed at the corresponding positions on the coding carrier. When the tooling substrate 1 is placed on the coding carrier, the lower grooves 10 at its bottom are inserted and docked with the limit pins, which can prevent the tooling substrate 1 from shaking and achieve precise positioning.

[0020] Positioning members 2 for limiting the position of the battery cover are symmetrically arranged on the top of the tooling substrate 1. The positioning members 2 include a plurality of uniformly distributed limit grooves 201 and anti-fooling step grooves 202. The limit grooves 201 and the anti-fooling step grooves 202 are both opened on the top of the tooling substrate 1, and the limit grooves 201 and the anti-fooling step grooves 202 are distributed along the length direction of the tooling substrate 1. The limit grooves 201 are used to facilitate the determination of the insertion direction of the battery cover to be coded. After a person picks up the battery cover, it can only be inserted into the limit grooves 201 in a fixed direction. If inserted in the reverse direction, it cannot be inserted into the limit grooves 201, which plays a role in precise positioning. One end of the limit groove 201 close to the length side of the tooling substrate 1 is open, which makes it more convenient to take out the battery cover placed in the limit groove 201.

[0021] The anti-fooling step grooves 202 are distributed circumferentially along the notch of the limit groove 201, and the anti-fooling step grooves 202 communicate with the limit groove 201. The anti-fooling step grooves 202 are convenient for accommodating and limiting the docking part of the battery cover, which plays a role in precise positioning. An anti-reverse column 3 is installed at the bottom of the limit groove 201. In this embodiment, the anti-reverse column 3 includes a cylindrical protrusion, which can prevent the battery cover from being installed upside down. When the battery cover is in the wrong up-down direction, the cylindrical protrusion can lift it up, so that the battery cover cannot be fitted into the limit groove 201.

[0022] A cover plate 4 is attached to the top of the tooling substrate 1. Upper handles 8 are installed at the centers of the side walls at both ends of the cover plate 4, which facilitates personnel to pick up the cover plate 4. In this embodiment, for the battery cover placed in the limit groove 201, its top surface is flush with the top of the tooling substrate 1, ensuring that when the cover plate 4 is attached to the top of the tooling substrate 1, it can exert pressure on the battery cover to prevent the battery cover from shifting, which is beneficial to further improving the stability of the position of the battery cover. A plurality of hollow parts 5 corresponding to the limit grooves 201 are penetrated through the cover plate 4. When the laser coding device is turned on, it is convenient for the laser to laser-engrave the surface of the battery cover within the limited range through the hollow parts 5. The hollow parts 5 are located directly above the limit grooves 201.

[0023] The cover plate 4 is provided with symmetrically arranged positioning holes 6 penetrating therethrough. The top of the tooling substrate 1 is provided with mounting grooves 7 corresponding to the positioning holes 6. The mounting grooves 7 are used to mount positioning pins matching the positioning holes 6. By using the positioning pins mounted on the tooling substrate 1, it is convenient for the positioning pins to pass through the positioning holes 6 when the cover plate 4 is attached to the tooling substrate 1, realizing the positioning of the cover plate 4 and preventing the cover plate 4 from shifting in position.

[0024] The working principle of the present utility model: The battery cover plates to be coded are sequentially placed in the fixed direction in the limiting grooves 201 on the tooling substrate 1. If the battery cover plates are placed in the reverse direction, they cannot be smoothly placed in the limiting grooves 201. The anti-fooling step grooves 202 are used to accommodate and limit the docking parts of the battery cover plates, and the anti-reverse posts 3 can prevent the upper and lower surfaces of the battery cover plates from being reversely installed. When the battery cover plates are placed in the reverse direction in the limiting grooves 201, they will be lifted by the anti-reverse posts 3. After the battery cover plates are positioned and placed, hold the upper handle 8 and cover the cover plate 4 on the tooling substrate 1, and align the positioning holes 6 on the cover plate 4 with the positioning pins mounted on the tooling substrate 1 to complete the positioning. Then hold the upper handle 8 and the lower handle 9, place the tooling substrate 1 with the cover plate 4 attached on the coding carrier table, and dock the lower grooves 10 at the bottom of the tooling substrate 1 with the limiting pins on the coding carrier table to complete all the positioning work. Finally, turn on the laser coding device, and the laser can pass through the hollow part 5 on the cover plate 4 to laser-engrave the surface of the battery cover plates within the limited range.

[0025] The above embodiments are only used to illustrate the technical method of the present utility model and not to limit it. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present utility model.
