[0002] In the existing battery structure, after the battery cell is placed in the steel shell, a top cover needs to be placed on the steel shell. In the current production process of the top cover, a layer of explosion-proof membrane needs to be installed inside the top cover, wherein the bottom surface of the explosion-proof membrane is a rubber surface, and the explosion-proof membrane is subsequently glued to the top cover by hot melting. In the prior art, the top cover equipped with the explosion-proof membrane is first placed in a jig, and the hot melt head is driven by a cylinder to press down the explosion-proof membrane in the top cover. The hot melt head is heated to make the rubber surface on the bottom surface of the explosion-proof membrane melt and stick to the top cover. The hot melt head is connected to the telescopic end of the cylinder through a connecting rod. Since the structure composed of the telescopic end of the cylinder and the connecting rod is relatively long, the telescopic end, the connecting rod and the hot melt head need to ensure coaxiality. After long-term operation, the coaxiality is difficult to ensure and is easy to shift, resulting in positional offset when the hot melt head is pressed down, resulting in the hot melt head being unable to accurately press down to the explosion-proof membrane in the top cover, affecting the production quality of the top cover and easily producing scrapped products.

[0012] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0013] Example
[0014] In order to solve the above technical problems, this embodiment provides a hot-melt device for a top cover and an explosion-proof film, such as Figure 1As shown, it includes a base 10, a hot melt head 20 arranged on the base 10, and a mounting seat 30 located on one side of the hot melt head 20. A pressure rod 40 is movably inserted on the mounting seat 30 above the hot melt head 20. A driving assembly 50 for pressing down the pressure rod 40 is arranged on the mounting seat 30. When the top cover equipped with the explosion-proof membrane moves between the pressure rod 40 and the hot melt head 20, the hot melt head 20 abuts against the bottom of the top cover to heat the top cover, and then the telescopic end of the driving assembly 50 presses down on the pressure rod 40. The pressure rod 40 is guided by the mounting seat 30 and pressed down on the explosion-proof membrane. The explosion-proof membrane is pressed tightly in the top cover, and the explosion-proof membrane is heated by the hot melt head 20 to make it melt and adhere to the top cover. The pressure rod 40 is connected with the reset component 60, and then when the driving component 50 is reset, the pressure rod 40 is lifted and reset by the reset component 60. The telescopic end of the driving component 50 is separated from the pressure rod 40, and the pressure rod 40 is guided by the mounting seat 30 to improve the stability of the pressure rod 40 pressing down, ensure that the pressure rod 40 can be accurately pressed down on the explosion-proof membrane of the top cover, improve the hot melting quality of the explosion-proof membrane and the top cover, and avoid scrapping and resulting in increased costs.
[0015] Specifically, in the above scheme, the mounting seat 30 is equipped with a guide column 70, and the pressure rod 40 is movably placed on the guide column 70. The pressure rod 40 and the guide column 70 are slidably matched, and the accuracy of the downward movement of the pressure rod 40 is improved through the guide column 70, and there will be no positional offset in long-term production, ensuring that the pressure rod 40 can be accurately pressed down on the explosion-proof membrane of the top cover. At the same time, the drive component 50 uses a telescopic cylinder, and the telescopic end of the cylinder is separated from the pressure rod 40. There is no requirement for coaxiality between the telescopic end of the cylinder and the pressure rod 40. As long as the telescopic end can be pressed down and abutted against the top of the pressure rod 40, the pressure rod 40 can be accurately pressed down on the explosion-proof membrane of the top cover through the guiding effect of the guide column 70, thereby improving the position accuracy.
[0016] Since the telescopic end of the driving assembly 50 is not connected to the pressure rod 40, the pressure rod 40 will not be reset when the telescopic end of the driving assembly 50 is reset. For this reason, a limit block 41 is provided on the top of the pressure rod 40, and the reset assembly 60 includes an elastic member sleeved on the pressure rod 40, and the two ends of the elastic member are respectively abutted on the limit block 41 and the guide column 70. Then, when the force of the driving assembly 50 on the pressure rod 40 is cancelled, the elastic force of the elastic member causes the pressure rod 40 to move upward and reset, and then the top cover that has been hot-melted is removed, and the next top cover to be processed is moved to the hot-melt head 20.
[0017] Among them, in some embodiments, a turntable can be used to transport the top cover, the top cover is set in the groove of the turntable, and the turntable rotates to transport the top cover between the pressure rod 40 and the hot melt head 20, and then the hot melt head 20 rises and abuts against the bottom of the top cover, thereby heating the top cover. To this end, this embodiment also includes a lifting component 21 arranged under the base 10, the driving end of the lifting component 21 is connected to the hot melt head 20, and the lifting component 21 can be a cylinder, and the telescopic end of the cylinder is connected to the bottom of the hot melt head 20, thereby driving the hot melt head 20 to move closer to or away from the top cover on the turntable.
[0018] Furthermore, a position detector 31 is provided on one side of the pressure rod 40 on the mounting seat 30. The position detector 31 may be a position sensor. The position of the pressure rod 40 is detected by the position detector 31 to ensure that the pressure rod 40 is reset into place before the next working cycle.
[0019] In the above scheme, it also includes a height detector 51 arranged above the driving component 50. The height detector 51 is used to detect the height position of the telescopic end of the driving component 50. The height detector 51 can be a height sensor. When the telescopic end of the driving component 50 is pressed down on the pressure rod 40 and the pressure rod 40 is made to abut against the explosion-proof membrane in the top cover, the height position of the telescopic end is detected by the height detector 51, and then the pressing stroke of the pressure rod 40 is detected, so as to ensure that the pressure rod 40 is accurately pressed down to the explosion-proof membrane in the top cover, avoid the problem that the pressure rod 40 is not pressed down into place, resulting in poor hot melting effect of the explosion-proof membrane, thereby improving the production quality of the top cover.
[0020] To summarize, the present application scheme comprises a pressure rod movably inserted on the mounting seat, a driving assembly is provided on the mounting seat, a hot melt head is abutted against the bottom of the top cover to heat the top cover, and then the telescopic end of the driving assembly is pressed down on the pressure rod, the pressure rod is guided by the mounting seat and pressed down on the explosion-proof membrane, thereby pressing the explosion-proof membrane tightly inside the top cover, and the explosion-proof membrane is hot-melted and adhered to the top cover by heating with the hot melt head, the pressure rod is connected to a reset assembly, and then when the driving assembly is reset, the pressure rod is lifted and reset by the reset assembly, the telescopic end of the driving assembly is separated from the pressure rod, and the pressure rod is guided by the mounting seat, so as to improve the stability of the pressure rod pressing down, ensure that the pressure rod can be accurately pressed down on the explosion-proof membrane of the top cover, improve the hot melting quality of the explosion-proof membrane and the top cover, and avoid product scrapping and cost increase.

Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
