Description

Technical Field

[0001] The utility model relates to the field of gluing and drying of lithium battery caps, in particular to a drying mechanism for a lithium battery cap gluing machine. Background Art

[0002] Lithium battery cap gluing refers to the step of applying glue to the battery cap during the lithium battery production process. This process is usually carried out in the early stages of battery assembly. The main purpose of gluing is to seal and fix the battery cap to ensure the safety and stability of the internal components of the battery.

[0003] In order to speed up the curing process after gluing, a drying mechanism is used to dry the lithium battery cap after gluing. The use of a drying mechanism can effectively speed up the curing process of the lithium battery cap after gluing and improve production efficiency.

[0004] The existing technology has the following deficiencies: Common heat sources in the drying mechanism of traditional lithium battery cap gluing machines include electric heating tubes, infrared lamps or heaters. Since the heat source in the drying mechanism is usually set above or on the upper side of the lithium battery cap, when the lithium battery cap is dried and heated after gluing, the glue on the surface of the lithium battery cap is affected by the direct exposure of the heat source, which will cause the glue to start to solidify from the outer surface. When the outer surface of the glue starts to solidify, the adhesion may be poor due to the insufficient curing speed near the contact surface with the lithium battery cap. This may cause the glue layer of the lithium battery cap to fall off during the subsequent assembly process, greatly affecting the production quality of the lithium battery.

[0005] Therefore, it is necessary to invent a drying mechanism for a lithium battery cap glue coating machine. Utility Model Content

[0006] To this end, the utility model provides a drying mechanism for a lithium battery cap gluing machine, which places the glued lithium battery caps on a tray or places the battery caps on a tray for gluing, and then inserts the tray carrying the battery caps into a cover shell, and heats the bottom of the tray from below by a hot air device arranged on the bottom of the cover shell. The tray conducts heat to the battery caps and causes the glue to dry and solidify from the contact surface, so as to solve the problem that the heat source in the drying mechanism is usually arranged above or on the upper side of the lithium battery cap. When the glued lithium battery caps are dried and heated, the glue on the surface of the lithium battery caps is directly exposed to the heat source, which will cause the glue to solidify from the outer surface. When the outer surface of the glue begins to solidify, the adhesion may be poor due to the insufficient curing speed near the contact surface with the lithium battery cap, which may cause the glue layer of the lithium battery cap to fall off during the subsequent assembly process.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drying mechanism for a lithium battery cap gluing machine, comprising a cover shell and a tray, wherein the side surface and the bottom surface of one side of the cover shell are set to be openings, and an air outlet is provided on the side of the cover shell opposite to the side opening, and a slide rail is fixedly installed on the inner wall of the cover shell, and the outer edge of the tray can be slid along the slide rail and inserted into the cover shell, and the top surface of the tray can be placed on the glue-coated lithium battery cap, and a hot air device is fixedly installed on the ground of the cover shell, and the hot air device can heat the bottom surface of the tray from below.

[0012] Preferably, a cabinet door is rotatably mounted on the lower side of the side opening of the cover shell, and a handle is fixedly mounted on the side of the cabinet door away from the cover shell.

[0013] Preferably, the top surface of the tray is provided with circular grooves, and the circular grooves are arranged in a rectangular array on the top surface of the tray. The top surface of the tray is also provided with strip grooves, and the strip grooves are evenly arranged on the top surface of the tray.
