Technical Field

[0001] The present invention relates to the technical field of material discharging jigs, and in particular to a cutting jig and a cutting method thereof. Background Art

[0002] In the processing of steel-shell batteries, it is necessary to cut the edges of the steel-shell batteries. In the existing process, most of the steel-shell batteries are cut by a discharge jig, and a camera is used to take pictures of the steel-shell batteries on the discharge jig, and simulate the cutting, and then the external cutting platform is directed to cut the steel-shell batteries. After the cutting is completed, the steel-shell batteries are photographed and tested to determine the cutting effect.

[0003] Most of the existing unloading jigs are made of steel to ensure their own strength. However, this material easily produces large light reflections when the detection camera takes pictures, thereby interfering with the picture results and causing unclear pictures. Therefore, improvements are needed. Summary of the Invention

A pressing member is provided on the first cover, which drives the first cover to move toward the second cover. The cutting hole is provided in the middle of the second cover.

[0010] Specifically, a clamping piece is provided on the second cover body, and the clamping piece is arranged outside the cutting hole. The clamping piece includes a clamping cylinder and a clamping block. The clamping cylinder drives the clamping block to lift or lower to achieve clamping or placement of the flange edge of the steel shell battery.

[0011] Specifically, a welding slag collecting trough is provided on the discharge jig, and the welding slag collecting trough is located below the positioning block. A welding slag collecting hole is provided on one side of the welding slag collecting trough, and the welding slag collecting hole is used to connect with an external negative pressure dust collector.

[0012] To achieve the above-mentioned purpose, the present invention also proposes a cutting method for controlling a discharge jig, comprising: S1, placing the steel shell battery to be cut on the positioning block of the discharge jig, and then the jig driving part drives the jig cover to move along the jig guide rail to the top of the discharge jig to perform positioning operations before cutting; S2, driving the jig cover to move downward by the clamping part to press the steel shell battery, and then cooperating with the clamping part to clamp the flange edge of the steel shell battery; S3, cooperating with the external cutting platform to perform visual photography positioning, ranging and cutting of the steel shell battery to be cut; S4, driving the jig cover to move upward by the clamping part, and then driving the jig cover to move along the jig guide rail in the opposite direction of the discharge jig to the throwing position by the jig driving part, and the flange edge of the steel shell battery is thrown away by loosening the clamping part.

The provision of the cutting hole 11 on the jig cover allows an external cutting platform to better identify the cutting range based on the cutting hole 11. The inner wall of the cutting hole 11 is inclined and coated with a bright gray ceramic layer and a Teflon layer to reduce interference with the visual camera when photographing, improve the visual camera's judgment of the weld after photographing, and enhance the recognition accuracy of the visual camera.

[0023] The photographing surface 12 has a slope of 50 to 70 degrees, and an overall roughness of ra0.8 to ra1.6. In this embodiment, the 50-degree slope and ra0.8 overall roughness of the photographing surface 12 achieve low light reflection, preventing any impact on the image quality of the visual camera, thereby improving the recognition accuracy of the visual camera.

[0024] A cutting station is provided on the jig machine 22, and the unloading jig 10 is located on the cutting station. The jig machine 22 is provided with a jig guide rail 13 and a jig drive 14 leading to the cutting station.

In this embodiment, the clamping member 18 is provided to facilitate clamping the flange edge, thereby facilitating the stability of the steel-cased battery during the cutting process, and at the same time facilitates the clamping of flange edge waste to the discarding station for discarding.

[0026] The discharge jig 10 is provided with a slag collection trough 21, located below the positioning block 101. A slag collection hole is provided on one side of the slag collection trough 21, which is connected to an external negative pressure dust collector. In this embodiment, the slag collection trough 21 is provided to facilitate the collection of slag generated during the cutting process.
