[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] Embodiment 1

[0031] like Figures 1 to 3 As shown, the utility model provides a lithium battery core shelling device, comprising a shell 1 and a guide block 3 detachably arranged on the shell 1 .

[0032] One end of the housing 1 is an open end housing 1, and a chamber 2 for accommodating the winding core to be loaded is provided inside the housing 1, and the chamber 2 is communicated with the open end;

[0033] The guide block 3 is arranged at the open end of the shell 1, and a guide groove 4 is opened inside the guide block 1 and extends from top to bottom; the guide groove 4 is trapezoidal in shape and extends from top to bottom, and its upper groove width is greater than the lower groove width of the guide groove 4, and the groove width of the guide groove 4 is greater than the width of the winding core to be loaded.

[0034] When the utility model processes the winding core into the shell, the winding core is guided by the guide block 3 with the guide groove 4 provided inside, so that the winding core is more easily loaded into the inner cavity of the shell 1, and the opening end of the shell 1 can be prevented from damaging the surface of the winding core.

[0035] As a further technical solution, Figure 2 As shown, a card slot 10 is provided at the open end of the housing 1 , and a card block 11 is provided at the bottom of the guide block 3 . The card block 11 is used to be inserted into the card slot 10 to realize the guide block 3 being connected to the open end of the housing 1 .

[0036] When the guide block 3 and the opening of the shell 1 are aligned, the positioning members of the card slot 10 and the card block 11 ensure that the positions of the opening of the guide block and the opening of the shell are always aligned without displacement, thereby ensuring that when the winding core enters the interior of the shell 1, it will not be scratched by the concave and convex surface caused by the misalignment of the guide slot and the chamber.

[0037] As a further technical solution, Figure 3 , Figure 4 As shown, a heating component is provided on the outer surface of the shell 1, and the heating component is used to heat the shell 1. The utility model utilizes the heating component to heat the lithium battery shell, and the heating temperature does not exceed 60°C, which can soften the shell to facilitate the core to be loaded into the shell, and can also prevent the temperature from being too high to avoid damage to the battery caused by excessive temperature.

[0038] The heating assembly includes a first heating device and a second heating device, both of which are arranged in a ring shape on the outer surface of the shell 1; the first heating device and the second heating device are connected at a first connection through a door shaft 9, and at a second connection through a buckle 12.

[0039] The first heating device and the second heating device have the same structure. The outer shell of the heating device is made of insulating material, and a heating block 7 is arranged on the inner wall thereof. The heating block 7 is arranged in an array on the inner wall of the heating device. The heating block 7 can be selected from components such as electric heating wires. The electric heating wires are generally made of nickel-chromium alloy or iron-chromium alloy. The principle of the heating block 7 is that the resistor generates heat after being energized. Many heating blocks 7 are connected in series or in parallel and powered by an external power supply. In addition, a control switch 8 for controlling the first heating device 5 and the second heating device is provided on the first heating device 5.

[0040] It is understandable that when multiple heating blocks 7 on the heating device are connected in series, one end of the head end heating block on the first heating device is connected to the external power supply through the control switch 8, one end of the tail end heating block is connected to the head end heating block on the second heating device, and the tail end heating block on the second heating device is connected to the external power supply to form a closed loop. Similarly, the principle when multiple heating blocks 7 are connected in parallel is similar, and the heating blocks on the first heating device and the second heating device are connected to the external power supply to form a closed loop.

[0041] The control switch 8 can be selected as a temperature control switch, which is connected in series between the resistance wire and the external power supply. The temperature control switch detects the temperature change of the resistance wire and adjusts the current of the resistance wire, thereby controlling the temperature of the resistance wire. The temperature control switch can not only accurately control the temperature of the resistance wire, but also has the characteristics of safety and reliability. It is a commonly used temperature control solution in the electric heating circuit.

[0042] The working principle of the utility model is:

[0043] When personnel need to shell the core, the shell 1 to be loaded with the core is placed at the bottom end of the guide block 3, and the chamber 2 and the guide groove 4 are aligned by positioning the block 11 and the slot 10. Then the heating device 5 is installed on the surface of the shell 1 and fixed by the buckle 12. The shell 1 is heated by the heating block 7. Then, the lithium battery core is placed in the opening of the guide block 3, and the core is pressed into the shell 1 through the guide groove 4 to complete the shell processing.

[0044] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
