[0037] Embodiment 1

[0038] See also Figure 1 and 2 As shown, the present invention is a battery shell coating device, comprising a conveyor line 1 and a coating mechanism 2 located on one side of the conveyor line 1. A pushing assembly is provided on one side of the conveyor line 1 for pushing the battery shell to the coating mechanism 2.

[0039] Specifically, the push assembly includes a fixed plate 101, the fixed plate 101 is connected to a fixed rod of the frame of the conveyor line 1, the fixed plate 101 is connected to a cylinder 102, and is connected to a push plate 103 through a telescopic rod of the cylinder 102. The fixed plate 101 is connected to a baffle 104 through bolts, which is used to position the battery shell 7 transported by the conveyor line 1 through the baffle 104, so that the battery shell 7 is facing the coating mechanism 2, so that the push plate 103 can accurately push the battery shell 7 into the coating mechanism 2.

[0040] like Figures 3 to 5 As shown, the laminating mechanism 2 includes a platform 201, a bracket plate 21 is fixedly connected to the upper surface of the platform 201, a through slot 202 is opened on the platform 201, and a film-pulling plate 3 is connected to the lower surface of the platform 201 through a lifting assembly, and a first telescopic cylinder 6 is fixedly connected thereto, the first telescopic cylinder 6 is a pneumatic cylinder or an electric push rod, the first telescopic cylinder 6 is connected to the first film pressing roller 601 through a bracket, and the first negative pressure adsorption block 301 and the first film pressing roller 601 correspond to the positions of the through slot 202.

[0041] The lifting assembly is driven by a cylinder, or the lifting assembly includes two guide rods 302, the upper ends of the two guide rods 302 are fixedly connected to the platform 201, and the lower ends are fixedly connected to a mounting plate 303, the mounting plate 303 is fixedly connected to a motor 304, and the output shaft of the motor 304 is connected to a screw rod 305, and the upper end of the screw rod 305 is rotatably connected to the platform 201. The film drawing plate 3 is movably connected to the two guide rods 302 through a linear bearing, and is connected to a screw nut that cooperates with the screw rod 305, and the film drawing plate 3 is moved up and down by the rotation of the screw rod 305.

[0042] A first negative pressure adsorption block 301 is fixedly connected to the side of the film pulling plate 3. The first negative pressure adsorption block 301 has a cavity inside and negative pressure adsorption holes are evenly distributed on the surface. The first negative pressure adsorption block 301 is connected to the negative pressure device and is used to adsorb and fix the film through the negative pressure adsorption holes on the surface.

[0043] like Figure 6 As shown, the bracket plate 21 is in a vertical position, and is provided with a passage 203 for the battery shell to pass through, and the passage 203 corresponds to the position of the through slot 202. A film roll frame 204, a second negative pressure adsorption block 205 and a cutter assembly 5 are connected to one side of the bracket plate 21. The film roll frame 204 is used to place the film roll, and the film roll is placed horizontally in the axial direction. The bracket plate 21 is also equipped with a guide roller assembly for supporting and guiding the film so that the film passes through the surface of the second negative pressure adsorption block 205.

[0044] like Figure 7 As shown, the cutter assembly 5 includes a cylinder frame 501 connected to the support plate 21, and a cutter cylinder 502 is connected through the cylinder frame 501, and a cutter 503 is connected to the telescopic end of the cutter cylinder 502. The blade of the cutter 503 is a sawtooth structure, which is convenient for cutting the film 8. At the same time, the cutter 503 is connected to a heating component for heating the cutter 503, thereby improving the convenience of cutting the film 8.

[0045] like Figure 8 As shown, the end of the film 8 is adsorbed on the surface of the second negative pressure adsorption block 205 , and the lifting assembly drives the film pulling plate 3 to rise, pass through the through slot 202 , and rise to a position corresponding to the position of the second negative pressure adsorption block 205 .

[0046] like Fig. 9 As shown, at this time, the valve on the pipe connected to the second negative pressure adsorption block 205 is closed, the second negative pressure adsorption block 205 stops adsorbing the film 8, and the first negative pressure adsorption block 301 is opened, so that the end of the film 8 is adsorbed and fixed on the surface of the first negative pressure adsorption block 301, and moves downward through the film pulling plate 3, and the film 8 is pulled downward by the first negative pressure adsorption block 301 and passes through the through slot 202.

[0047] like Fig.10 As shown, the battery housing 7 is pushed through the passage 203 by the pushing assembly, so that the film 8 is wrapped around the outside of the battery housing 7. When the battery housing 7 moves to the right and the film 8 is driven, the film pulling plate 3 rises synchronously to prevent the film 8 from being pulled and deformed.

[0048] At the same time, a support roller 206 is rotatably connected in the through slot 202, which is used to support the battery shell 7 and roll the film 8 to fit the surface of the battery shell 7. An upper pressing roller 207 is rotatably connected in the passage 203, which is used to roll the film 8 to fit the surface of the battery shell 7 during the movement of the battery shell 7. That is, when the battery shell 7 passes through the passage 203, the film 8 is rolled and fit to the surface of the battery shell 7 by the rolling action of the support roller 206 and the upper pressing roller 207, thereby providing a laminating effect of the film 8.

[0049] like Figure 4 and 11 As shown, a second telescopic cylinder 4 is connected to the other side of the bracket plate 21, and the second telescopic cylinder 4 is connected to a second film pressing roller 401 through the bracket. Specifically, the film 8 is adsorbed by the second negative pressure adsorption block 205, the cutter cylinder 502 is actuated, and the cutter assembly 5 is used to cut the film 8.

[0050] After the film 8 is cut, the second film pressing roller 401 is driven downward by the second telescopic cylinder 4 so that one end of the film 8 is pressed and attached to the end side of the battery housing 7. After completion, the second film pressing roller 401 is raised and reset.

[0051] like Fig.12 As shown, the first film pressing roller 601 is moved upward by the first telescopic cylinder 6 to roll and press the other end of the film 8 to fit the end side of the battery shell 7, that is, the two ends of the film 8 are folded in half and fit to the end side of the battery shell 7, so that the entire film is completely surrounded and covered on the surface of the battery shell 7, thereby effectively improving the adhesion between the whole and the battery shell, avoiding falling off, and ensuring the protection effect of the battery shell.

[0052] Embodiment 2

[0053] like Figure 4 , 11 As shown in 12, on the basis of Example 1, the platform 201 is fixedly connected to the pressing cylinder 208 through a fixed frame, and the telescopic end of the pressing cylinder 208 is fixedly connected to the pressure plate 209, which is used to press down and fix the battery shell 7 when the first telescopic cylinder 6 and the second telescopic cylinder 4 are in action, so that when the first film pressing roller 601 and the second film pressing roller 401 are rolling the film, the battery shell 7 will not move accidentally, thereby ensuring that the first film pressing roller 601 and the second film pressing roller 401 have a certain extrusion force on the end side of the battery shell 7, which can effectively provide a rolling effect on the film and ensure that the film and the battery shell 7 fit closely.
