Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with examples, which are only preferred implementations of the present invention, and are not limitations of the present invention.

[0037] The following is a fully automatic casing cutting method for a lithium battery provided by the present invention, which includes the following steps:

[0038] Step 1. Put the lithium battery into the slit transfer device to smooth the lead posture of the lithium battery. The lead of the lithium battery is passed forward by the transfer device under the guidance of the slit, so that the lead posture of each lithium battery same;

[0039] Step 2. Transfer the lithium battery to the leg fixing device to make the leg of the lithium battery, so that the two pins of the lithium battery are arranged to be parallel to each other and perpendicular to the end face of the lithium battery, so that the subsequent detection station can detect the pins. foot;

Abstract

The invention discloses a full-automatic sleeve pin-shearing method for a lithium battery and a sleeve pin-shearing machine; the full-automatic sleeve pin-shearing method for the lithium battery comprises the following steps of step 1, placing the lithium battery into a fine seam conveying device, so as to smoothen the pin postures of the lithium battery; step 2, transferring the lithium battery to a pin arranging device to perform pin arranging on the lithium battery; step 3, transferring the lithium battery to a polarity detection device before phase change for judging whether the polarity is staggered or not; and step 4, transferring the lithium battery to a polarity conversion clamp, wherein if the polarity detection device judges that the polarity is not staggered, the polarity conversion clamp does not rotate; and if the polarity detection device judges that the polarity is staggered, the polarity conversion clamp rotates by 180 degrees. The lithium batteries can be orderly arranged through simple conveying, pin arranging, detection and steering steps, and the polarity of the pins of the lithium batteries is the same as the preset polarity, so that the problems of skewing andpolarity dislocation are avoided, the product can enter a sleeve process smoothly, and the product yield is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, and more specifically, relates to a lithium battery automatic bushing cutting method and a casing cutting machine. Background technique [0002] Before cutting the casing of the lithium battery, the pins of the lithium battery need to be whole and polarized before being sent to the casing machine, otherwise the lithium battery leads behind the casing will be crooked or have wrong polarity. However, the traditional casing cutting machine usually uses multiple devices to implement each step separately, which is complicated and costly, and the probability of defective products will also increase during the transfer of the devices, thereby reducing the yield rate of lithium batteries. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a full-automatic casing cutting method for lithium batteries. Lithium batteries can be ar...
