Abstract

The invention discloses a rapid membrane sleeving machine of a cylindrical battery cell and a processing method of the rapid membrane sleeving machine. The rapid membrane sleeving machine of the cylindrical battery cell at least comprises a membrane supply device and a guide device, wherein the membrane supply device is used for supplying a tubular membrane and positioning the tubular membrane; the guide device at least comprises a guide part; the guide part is provided with a guide hole and one group of resilient sheets, the direction of the guide hole is the same as the extending direction of the battery cell and a tapered shape is enclosed by the resilient sheets; sharp ends of one group of the resilient sheets can be embedded into an inner circle of the tubular membrane and can be quitted from the inner circle. The rapid membrane sleeving machine disclosed by the invention has an ingenious design and a simple structure; the guide device is arranged and the tapered resilient sheetsare inserted into the tubular membrane and can be expanded, so that when the battery cell is pushed, the position of the tubular membrane is fixed; the battery cell can rapidly and accurately enter the tubular membrane; a detention condition and a tubular membrane deformation condition, caused by the fact that sizes of the battery cell and the tubular membrane are similar, are not caused; the membrane sleeving efficiency is easy to improve, the control requirements on positions are greatly reduced and the rapid membrane sleeving machine is easy to realize.

Description

technical field [0001] The invention relates to the field of electric core processing equipment, in particular to a cylindrical electric core rapid coating machine and a processing method thereof. Background technique [0002] When processing cylindrical batteries, it is necessary to cover the surface of the batteries to prevent damage and pollution. Therefore, various coating machines have sprung up, such as the patent application number: 201620043784.0, and the name is: a The Chinese patent of battery printing and casing equipment, which discloses a battery processing equipment that integrates casing, coding, gasketing device and heat shrinking treatment device, and adopts the method of casing the tubular film to the vertical Although the method of coating outside the battery core has a high degree of integration, it also has certain defects, mainly as follows: [0003] 1. Since the diameter of the inner circle of the tubular membrane is similar to the diameter of the bat...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the diameter of the inner circle of the tubular membrane is similar to the diameter of the battery core, it is necessary to accurately position the tubular membrane and the battery core during assembly to ensure a smooth assembly. The control is difficult, and even if it can be effectively guaranteed Their precise alignment, due to their similar size and the soft texture of the tubular film, during the nesting process, the tubular film is easily deformed due to the resistance of the side wall of the cell, and the efficiency of the film set

[0004] 2. Since the battery cell is in a vertical state, it is very easy to dump when it is assembled, resulting in the problem that it cannot be installed; although a certain fixing structure (clamp) is used to fix the battery cell, the area of ​​the battery cell is bound to be Covered by the fixture, the tubular membrane cannot be effectively set to the corresponding position, resulting in poor suitability and affecting the quality of the suit

[0005] 3. Since the tubular film is transported by two nip rollers, the tubular film transported by them cannot be kept fully stretched, which affects the subsequent package, and because the tubular film moves relative to the battery core, the tubular film during the moving process The positioning accuracy will also affect the subsequent package operation

[0006] 4. The electric core is fixed by the clamp for transportation, and the corresponding conveying line must be a circular line, and multiple fixtures are required to realize the synchronous transportation of multiple electric cores, which causes the complexity of the equipment structure and the increase of the cost
