Description

Technical Field

[0001] The utility model relates to the technical field of battery electrode sheet unloading and ejection, in particular to a battery electrode sheet shearing die waste unloading and ejection mechanism. Background Art

[0002] The thickness of a single new energy electrode sheet is 0.05-0.1. A shearing die is used to cut out the outline. The cut waste must be sucked away through the lower die mouth of the mold. If the material is blocked, it will cause subsequent cutting of double sheets, causing the edge of the electrode sheet to fall off and crack, or mixed with electrode waste, or the mold blade to crack. The following two technical solutions are generally used in the prior art: 1. Adding blowing holes to the upper blade of the mold; 2. Increasing the cutting depth, allowing the upper blade to cut very deeply, and pushing the waste down. Because the waste itself has edge stress or is uneven after cutting, simply adding blowing holes is not ideal, and the probability of failure when blowing down is high, there are great hidden dangers. Increasing the cutting depth, using the upper blade to directly push the waste down, the failure rate is zero, but when the cutting depth is very deep, it will cause great damage to the automation equipment mechanism, and the mold blade is more likely to be strained and cracked. For this reason, we propose a waste discharge and ejection mechanism for the battery electrode to the sheet shearing mold. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a battery electrode to sheet shearing die waste discharge ejection mechanism, through the provided ejection assembly and the reset assembly to cooperate with each other, to achieve in use, the blade is divided into two parts, one part of the role of cutting, the other part of the role of extruding the electrode sheet, directly through the mold closing action to control the extrusion action, more stable and reliable, to avoid action disorder.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: a battery electrode to sheet shearing mold waste unloading ejection mechanism, comprising:

[0005] An ejector assembly, the ejector assembly comprising an upper knife cutting frame, an opening provided on the bottom surface of the upper knife cutting frame; an ejector block inserted into the opening, a connecting column connected to the top surface of the ejector block, a flat plate fixed to the top of the connecting column, a roller movably connected to the flat plate, a connecting rod connected to the roller, a lever fulcrum passing through the connecting rod, and a force application rod provided at the lever fulcrum position;

[0006] The reset component is used to drive the top block to reset.

[0007] As a preferred solution of the battery electrode to sheet shearing die waste unloading ejection mechanism described in the utility model, wherein the connecting rod rotates along the lever fulcrum, and the connecting rod drives the flat plate to press downward.

[0008] As a preferred solution of the battery electrode to sheet shearing die waste unloading and ejecting mechanism described in the utility model, wherein the reset assembly includes a sleeve that fits with the connecting column and a spring connected to the top end of the sleeve.

[0009] As a preferred solution of the battery electrode to sheet shearing die waste unloading and ejecting mechanism described in the utility model, there are two connecting posts, and corresponding sleeves and springs are arranged at the positions of the two connecting posts.

[0010] As a preferred solution of the battery electrode to sheet shearing die waste unloading ejection mechanism described in the utility model, the top end of the spring is connected to the bottom surface of the flat plate, and the connecting column slides along the sleeve.

[0011] As a preferred solution of the battery electrode sheet shearing mold waste unloading and ejecting mechanism described in the utility model, it also includes a cutting support assembly, which includes a mold body and a battery electrode sheet arranged below the mold body.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The utility model achieves the effect of dividing the blade into two parts during use by the cooperation of the ejection assembly and the reset assembly, one part carries the function of cutting, and the other part carries the function of extruding the electrode sheet. The extrusion action is directly controlled by the mold closing action, which is more stable and reliable and avoids action disorder.

[0014] When in use, the mold body specifically includes an upper mold and a lower mold. When the upper mold and the lower mold are closed, the force rod will be directly pushed, and the force rod will push the connecting rod upward. The connecting rod is tilted through the lever fulcrum. At this time, the connecting rod is tilted downward, directly driving the plate and the connecting column to move downward, thereby driving the ejector block to move downward, and directly ejecting the waste. Since the sleeve is engaged in the upper mold position of the mold body, the spring will be compressed when the plate moves downward. In this way, when the mold body is reset, the spring will restore its deformation and directly push the plate to return to its original position. The downward pressing depth of the ejector block can be changed by changing the torque length to the lever fulcrum. BRIEF DESCRIPTION OF THE DRAWINGS
