Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing, specifically to an ultra-long and ultra-narrow double-end adhesive application device and process for cylindrical power lithium batteries. Background Technology

[0002] In the production process of cylindrical power lithium battery cells, after winding, tape needs to be applied to finish the process. However, the existing tape application equipment has a complex structure, and it is difficult to apply some narrow and long tapes. The entire tape application process is too cumbersome, which increases the difficulty of debugging and reduces the tape application yield. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an ultra-long and ultra-narrow double-end adhesive application device and its process for cylindrical power lithium batteries. The specific technical solution is as follows: A cylindrical power lithium battery ultra-long and ultra-narrow dual-end adhesive application device includes a large base plate, a first adhesive unwinding mechanism, a second adhesive unwinding mechanism, a first tape unwinding mechanism, a second tape unwinding mechanism, a main adhesive roller, an adhesive feeding moving module, an adhesive application mechanism, and a closing cell pressing mechanism. The first adhesive unwinding mechanism and the second adhesive unwinding mechanism are installed on one side of the large base plate. The first tape unwinding mechanism unwinds the tape to the first adhesive unwinding mechanism, and the second tape unwinding mechanism unwinds the tape to the second adhesive unwinding mechanism. The tape from the first adhesive unwinding mechanism or the second adhesive unwinding mechanism is guided into the adhesive application mechanism by the main adhesive roller. The adhesive feeding moving module is installed on the other side of the large base plate. The adhesive feeding moving module drives the adhesive application mechanism to move closer to or away from the winding station. The closing cell pressing mechanism is installed on the upper side of the large base plate. The closing cell pressing mechanism is used to press the cell to finish the adhesive application.

[0004] As a preferred embodiment of the present invention, the first glue-opening mechanism includes a first cylinder, a moving block, a slide rail, a sliding roller, a first glue-passing roller, and a second glue-passing roller. The first cylinder drives the moving block to move up and down. The moving block is slidably connected to the slide rail. The slide rail is fixedly installed on the base plate. The first glue-passing roller and the second glue-passing roller are rotatably installed on the base plate and located on both sides of the sliding roller.

[0005] As a preferred embodiment of the present invention, the first adhesive release mechanism and the second adhesive release mechanism have the same structure.

[0006] As a preferred embodiment of the present invention, the adhesive applicator includes a U-shaped base, an adhesive applicator wheel, a first transition wheel, a second transition wheel, an adhesive tape pressing cylinder, a pressure plate, an adhesive tape cutting cylinder, and a cutter. The adhesive applicator wheel, the first transition wheel, and the second transition wheel are rotatably installed in the U-shaped base from top to bottom. The adhesive tape arrives at the winding station sequentially from the second transition wheel, the first transition wheel, and the adhesive applicator wheel. The adhesive pressing cylinder drives the pressure plate to press the adhesive tape, and the adhesive tape cutting cylinder drives the cutter to cut the adhesive tape.

[0007] In a preferred embodiment of the present invention, the piston rod of the tape-cutting cylinder is connected to a hinge block, and a cutter is mounted on the side of the hinge block.

[0008] As a preferred embodiment of the present invention, the tailing piezoelectric cell mechanism includes a first translation cylinder, a first translation plate, a second translation cylinder, a second translation plate, and a piezoelectric cell roller. The first translation cylinder is installed on the upper side of the base plate, and the first translation cylinder drives the first translation plate to move. The second translation cylinder is installed on the first translation plate, and the second translation cylinder drives the second translation plate to move. The piezoelectric cell roller is rotatably installed in the second translation plate.

[0009] A process for applying adhesive to an ultra-long and ultra-narrow double-end of a cylindrical power lithium battery involves the following steps using the aforementioned ultra-long and ultra-narrow double-end adhesive application device for cylindrical power lithium batteries. (1) The first tape unwinding mechanism unwinds the tape to the first tape unwinding mechanism, and the second tape unwinding mechanism unwinds the tape to the second tape unwinding mechanism. The tape from the first tape unwinding mechanism or the second tape unwinding mechanism is guided into the tape application mechanism by the main tape roller. (2) The closing cell pressing mechanism presses down on one side of the cell; (3) The glue feeding moving module drives the glue application mechanism to move closer to the winding station. The tape sticks to one end of the battery cell. The battery cell rotates a set number of times to wind and apply the tape. The tape cutting cylinder drives the cutter to cut the tape.

[0010] Beneficial effects: The ultra-long and ultra-narrow double-end adhesive applicator for cylindrical power lithium batteries has a reasonable design and process. The first tape unwinding mechanism unwinds the tape to the first unwinding mechanism, and the second tape unwinding mechanism unwinds the tape to the second unwinding mechanism. The tape from either the first or second unwinding mechanism is guided into the adhesive applicator by the main glue roller. The adhesive feeding moving module drives the adhesive applicator to move closer to the winding station. The tape adheres to one end of the battery cell, and the battery cell rotates a set number of turns to wind and apply the tape. The tape cutting cylinder drives the cutter to cut the tape, achieving one-to-one adhesive application. Different specifications of adhesive can be used, and there is no need for pre-prepared adhesive. The two tape unwinding mechanisms can quickly connect and unwind the tape, resulting in high adhesive application efficiency. Attached Figure Description
