[0034] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0035] As Figures 1 to 5As shown in the figure, the present utility model discloses an assembly and pressing device for a button cell assembly system, which includes a base 1, an assembly device 2 and a pressing device 3 provided on the base 1; wherein, the assembly device 2 includes an assembly fixture 21, a positioning fixture 22 and an assembly translation driving device 23 for driving the assembly fixture 21 and the positioning fixture 22 to translate. The assembly translation driving device 23 can adopt a linear guide rail. The positioning fixture 22 is located above the assembly fixture 21, and the moving trajectories of the assembly fixture 21 and the positioning fixture 22 pass through the pressing device 3.

[0036] In the present utility model, the assembly fixture 21 is used to support various materials of the button cell, the pressing device 3 is used to press the second pole case and the first pole case of the button cell, and the positioning fixture 22 is used to position the second pole case and the first pole case of the button cell to prevent misalignment of the second pole case and the first pole case, thereby ensuring accurate pressing of the second pole case and the first pole case.

[0037] In an embodiment of the present utility model, the positioning fixture 22 includes a first positioning member 221 and a second positioning member 222 which are arranged above the assembly fixture 21 and opposite to each other, and an opening and closing driving device (not shown) for driving the first positioning member 221 and the second positioning member 222 to open and close relatively. The first positioning member 221 is provided with a positioning notch 2211. The positioning notch 2211 is provided with a first pole case positioning recess 22111 and a second pole case positioning recess 22112 which respectively match the first pole case and the second pole case. The second positioning member 222 is provided with a limiting notch 2221. The limiting notch 2221 is opposite to the positioning notch 2211, and an elastic limiting piece 223 is arranged inside the limiting notch 2221. The elasticity of the elastic limiting piece 223 can drive the first pole case and the second pole case to respectively fit into the first pole case positioning recess 22111 and the second pole case positioning recess 22112, thereby positioning the first pole case and the second pole case. Among them, the positioning fixture 22 and the assembly fixture 21 can be installed on an assembly base 241, and the assembly base 241 is connected to the assembly translation driving device 23 and is driven to translate by the assembly translation driving device 23.

[0038] In an embodiment of the present utility model, the working mode of the positioning fixture 22 can be:

[0039] Before placing the first pole case on the assembly fixture 21, the opening and closing driving device controls the first positioning member 221 and the second positioning member 222 to open relatively. After placing the first pole case on the assembly fixture 21, the opening and closing driving device then controls the first positioning member 221 and the second positioning member 222 to close relatively to position the first pole case; when preventing the second pole case, it is not necessary to control the first positioning member 221 and the second positioning member 222 to open relatively;

[0040] Before the pressing device 3 presses the first pole case and the second pole case, the opening and closing driving device controls the first positioning member 221 and the second positioning member 222 to open relatively to avoid interference between the first positioning member 221 and the second positioning member 222 with the pressing device 3. After the pressing device 3 completely presses the first pole case and the second pole case, the opening and closing driving device then controls the first positioning member 221 and the second positioning member 222 to close relatively to prevent the problem of material dropping when the assembly jig 41 moves.

[0041] In an embodiment of the present utility model, the assembly jig 21 may include a jig base 2111, a supporting column 212, and an assembly spring 213; the supporting column 212 is slidably connected to the jig base 2111 up and down, the assembly spring 213 is disposed between the jig base 2111 and the supporting column 212, and the supporting column 212 is used to support the first pole case. The assembly spring 213 is disposed between the jig base 2111 and the supporting column 212 so that the supporting column 212 has elastic telescopic ability, which can effectively avoid the feeding mechanism of the button battery assembly system from making mistakes and crushing the first pole case, nickel foam, lithium sheet, separator, pole piece, and second pole case that are sequentially placed on the supporting column 212. At the same time, it can also make the pressing device 3 apply force to the first pole case and the second pole case slowly to ensure the pressing effect of the first pole case and the second pole case. Among them, the jig base 2111 is provided with a sliding groove 2111, the upper side of the sliding groove 2111 is open and is fitted with a hollow cover 214, the supporting column 212 passes through the cover 214 and is inserted into the sliding groove 2111, the side wall of the supporting column 212 is provided with a retaining edge 2121 that is movably abutted against the lower side of the cover 214, the assembly spring 213 is disposed in the sliding groove 2111, and both sides of the assembly spring 213 respectively abut against the lower side of the retaining edge 2121 and the bottom of the sliding groove 2111.

[0042] In an embodiment of the present utility model, the pressing device 3 includes a pressing fixture 31 and a pressing lifting device 32 for driving the pressing fixture 31 to lift and lower. The pressing lifting device 32 can adopt a telescopic cylinder or a telescopic motor.

Specifically, the pressing fixture 31 includes a fixture top seat 311, a pressing column 312, and a pressing spring 313. The pressing column 312 is slidably connected to the fixture top seat 311 up and down. The pressing column 312 is used to apply pressure to the second pole case. The pressing spring 313 is arranged between the fixture top seat 311 and the pressing column 312 so that the pressing column 312 can elastically stretch and contract. In this way, the pressing column 312 can slowly apply pressure to the second pole case to ensure the pressing effect of the first pole case and the second pole case. Among them, the fixture top seat 311 is provided with a sliding groove 3111. The lower side opening of the sliding groove 3111 is fitted with a hollow sealing cap 314.
