DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Referring to Figures 1-6 A one-piece lithium electrode sheet coating machine, comprising a coating machine shell 1, one end of the coating machine shell 1 is provided with a U-shaped frame 2, the bottom end inside the U-shaped frame 2 is provided with two guide sticks 11, both ends inside the U-shaped frame 2 are provided with two spraying heads 4, the outer side of the spraying head 4 is fixed with a T-shaped fixed block 5, the inside of the U-shaped frame 2 is provided with a moving mechanism for moving the two T-shaped fixed blocks 5;

[0022] The moving mechanism comprises two longitudinal threaded rods 7, the two longitudinal threaded rods 7 are located at both ends inside the U-shaped frame 2, and the longitudinal threaded rod 7 is located at the top of the guide stick 11, the outer side of the longitudinal threaded rod 7 is threadedly connected with a rectangular moving seat 6, a limiting assembly is arranged between the rectangular moving seat 6 and the T-shaped fixed block 5, one side of the longitudinal threaded rod 7 is fixed with a longitudinal rotating shaft 9, the outer side of the longitudinal rotating shaft 9 is fixed with a transmission gear 10, the two transmission gears 10 are meshed and connected, the other side of the U-shaped frame 2 is bolted with a driving motor 3, and the output end of the driving motor 3 is fixedly connected with one of the longitudinal threaded rods 7;

[0023] The longitudinal rotating shaft 9 penetrates the inside of the U-shaped frame 2 and is rotatably connected with the U-shaped frame 2 through a bearing, so that the longitudinal rotating shaft 9 can penetrate the inside of the U-shaped frame 2 and can rotate in the inside of the U-shaped frame 2. Here, through the operation of the driving motor 3, one of the longitudinal threaded rods 7 can rotate, so that the corresponding longitudinal rotating shaft 9 and the transmission gear 10 can rotate. Through the meshing connection of the two transmission gears 10, the rotating directions of the two longitudinal threaded rods 7 are opposite.

[0024] A longitudinal smooth rod 8 is provided at the bottom of the longitudinal threaded rod 7 and inside the U-shaped frame 2. The longitudinal smooth rod 8 passes through the interior of the rectangular moving seat 6 and is slidably connected to the rectangular moving seat 6, so that the rectangular moving seat 6 can slide on the outside of the longitudinal smooth rod 8. The rotation of the longitudinal threaded rod 7 causes the rectangular moving seat 6 to slide on the outside of the longitudinal smooth rod 8, thereby allowing the spray head 4 to move.

[0025] Here, the operation of the drive motor 3 causes one of the longitudinal threaded rods 7 to rotate, which in turn causes one of the corresponding longitudinal rotating shafts 9 and the transmission gear 10 to rotate. Through the meshing connection of the two transmission gears 10, the two longitudinal threaded rods 7 rotate in opposite directions. The rotation of the two longitudinal threaded rods 7 causes the two rectangular moving seats 6 to move in opposite directions, and the rectangular moving seats 6 can slide laterally on the outside of the longitudinal light rod 8, thereby allowing the spray head 4 to move. Through the movement of the two spray heads 4, the spraying efficiency of this device can be improved, dead angles can be reduced, and the spraying quality can be improved.

[0026] The limiting component includes a rectangular limiting block 12, which is located inside the rectangular moving seat 6 and fixedly connected to it. An L-shaped sliding block 13 is fixed to one end of the rectangular limiting block 12, and a rectangular push block 14 is fixed to the bottom of the L-shaped sliding block 13. A transverse rigid spring 15 is provided on both sides of one end of the L-shaped sliding block 13, and the transverse rigid spring 15 is located inside the rectangular moving seat 6.

[0027] The top of the rectangular limiting block 12 is provided with a first inclined surface, and the bottom of the T-shaped fixing block 5 is provided with a second inclined surface that matches the first inclined surface. By setting the first and second inclined surfaces, when the T-shaped fixing block 5 contacts the rectangular limiting block 12, the rectangular limiting block 12 can slide inside the rectangular moving seat 6. The sliding of the rectangular limiting block 12 causes the transverse rigid spring 15 to deform under force.

[0028] The rectangular movable seat 6 has a T-shaped groove inside. The T-shaped fixing block 5 and the rectangular movable seat 6 are slidably connected through the T-shaped groove, so that the T-shaped fixing block 5 can slide into the interior of the rectangular movable seat 6. When the rectangular limiting block 12 enters the interior of the T-shaped fixing block 5, the T-shaped fixing block 5 can be fixed inside the T-shaped fixing block 5.

[0029] Here, a disassembly mechanism is needed for the T-shaped fixing block 5. The rectangular push block 14 is pushed so that the L-shaped sliding block 13 can slide inside the rectangular moving seat 6, thereby causing the transverse rigid spring 15 to contract under force. When the rectangular limit block 12 moves out of the interior of the T-shaped fixing block 5, the T-shaped fixing block 5 can be disassembled, thereby allowing the spray head 4 to be disassembled.

[0030] By setting two spray heads 4 that move in opposite directions, the spraying range can be flexibly adjusted according to the needs, which can effectively reduce the workload of a single spray head 4, thereby significantly improving the spraying efficiency. It can ensure that the spray head 4 can cover every corner of the electrode sheet, avoiding the problem of dead corners in the spraying process. The spray head 4 is easy to disassemble, which facilitates the maintenance and adjustment of the equipment.

[0031] Working principle: The operation of the drive motor 3 causes one of the longitudinal threaded rods 7 to rotate, which in turn causes one of the corresponding longitudinal rotating shafts 9 and the transmission gear 10 to rotate. Through the meshing connection of the two transmission gears 10, the two longitudinal threaded rods 7 rotate in opposite directions. The rotation of the two longitudinal threaded rods 7 causes the two rectangular moving seats 6 to move in opposite directions, and the rectangular moving seats 6 can slide laterally on the outside of the longitudinal smooth rod 8, thereby allowing the spray head 4 to move. Through the movement of the two spray heads 4, the spraying efficiency of this device can be improved, dead angles can be reduced, and the spraying quality can be improved.

[0032] The T-shaped fixing block 5 needs to be disassembled by pushing the rectangular push block 14 so that the L-shaped sliding block 13 can slide inside the rectangular moving seat 6, thereby causing the transverse rigid spring 15 to be compressed. When the rectangular limit block 12 moves out of the interior of the T-shaped fixing block 5, the T-shaped fixing block 5 can be disassembled, thereby allowing the spray head 4 to be disassembled.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
