DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a semi-automatic winding device for lithium battery production provided by the utility model; Figure 2 It is a structural schematic diagram of the winding mechanism in the utility model; Figure 3 It is a structural schematic diagram of the cutting mechanism in the utility model; Figure 4The figure is a schematic diagram of the structure of the installation mechanism in the utility model. A semi-automatic winding device for lithium battery production includes a workbench 1, a placing rack (not shown in the figure) is arranged in front of the workbench 1, a winding mechanism 2 and a support 5 are fixedly connected to one side of the top of the workbench 1, and the inner wall of the support 5 is rotatably connected to a guide roller 6; the number of guide rollers 6 is four, and two are in a group, and a cutting mechanism 3, the cutting mechanism 3 includes a cutting frame 31 fixed to the other side of the top of the workbench 1, and an electric cylinder 32 is arranged on the cutting frame 31, and the top rod of the electric cylinder 32 is fixedly connected to a cross bar 33, and the inner wall of the cross bar 33 is clamped. A cutter 34 is connected; a mounting mechanism 4, the mounting mechanism 4 includes a slot 41 opened at the bottom of the cross bar 33, a fixing rod 42 is slidably connected to the inner wall of the cross bar 33, one end of the fixing rod 42 is fixedly connected to a pull block 43, the other end of the fixing rod 42 extends into the slot 41, a spring 44 is provided on the outer side of the fixing rod 42, one end of the spring 44 is fixedly connected to one side of the cross bar 33, the other end of the spring 44 is fixedly connected to one side of the pull block 43, a fixing hole 45 is opened on one side of the cutter 34, and the fixing hole 45 is clamped with the fixing rod 42.

[0021] It should be noted that: the rolled lithium battery diaphragm is installed on the placement rack, and then the lithium battery diaphragm is pulled to pass between the two guide rollers 6, and then through the cutting rack 31, and then through the other two guide rollers 6, and connected to the winding mechanism 2, and then the winding mechanism 2 is started to roll up the lithium battery diaphragm. The lithium battery diaphragm can be smoothed by the two sets of guide rollers 6. After the winding is completed, the electric cylinder 32 is started to make the cross bar 33 drive the cutter 34 to descend, and then the lithium battery diaphragm can be automatically cut, which improves the work efficiency. While improving the working efficiency, the cutting part of the lithium battery diaphragm is also relatively flat. When the cutter 34 is damaged, the pull block 43 is pulled to separate the fixing rod 42 from the fixing hole 45, so that the spring 44 is stretched, and the damaged cutter 34 can be removed from the slot 41, and then the new cutter 34 is inserted into the slot 41, and then the pull block 43 is released. The resilience of the spring 44 can automatically insert the fixing rod 42 into the fixing hole 45, so that the cutter 34 is fixed on the cross bar 33, which is easy to operate and improves the flexibility of the equipment.

[0022] In the specific implementation process, Figure 1 and Figure 3 As shown, the cutting mechanism 3 further includes a positioning block 35 fixed to one side of the crossbar 33 , and there are two positioning blocks 35 . A positioning rod 36 is fixedly connected to the inner wall of the cutting frame 31 , and the positioning block 35 is slidably connected to the positioning rod 36 .

[0023] It should be noted that when the cross bar 33 moves, the positioning block 35 can be driven to move, and the positioning block 35 moves through the positioning rod 36, so that the cross bar 33 can drive the cutter 34 to remain stable during the lifting process.

[0024] refer to Figure 1and Figure 2 As shown, the winding mechanism 2 includes a bracket 21 fixed to the top of the workbench 1, the bracket 21 is fixedly connected to a motor 22 through a support plate, the output shaft of the motor 22 is fixedly connected to a driving wheel 23, the outer side of the driving wheel 23 is meshingly connected to a driven wheel 24, the center of the driven wheel 24 is fixedly connected to a limiting rod 25, the outer side of the limiting rod 25 is fixedly connected to a limiting disk, a core barrel 26 is arranged on the outer side of the limiting rod 25, and a through hole is opened on the inner wall of the core barrel 26.

[0025] The winding mechanism 2 further comprises a screw rod 27 threadedly connected to the inner wall of the bracket 21 , one end of the screw rod 27 is rotatably connected to a conical block 28 , the other end of the screw rod 27 is fixedly connected to a rotating wheel 29 , and an anti-slip sleeve is arranged on the outer side of the rotating wheel 29 .

[0026] It should be noted that: rotating the rotating wheel 29 causes the screw rod 27 to drive the conical block 28 toward the bracket 21. The anti-slip sleeve can increase the friction between the operator's hand and the rotating wheel 29. Then, the core barrel 26 is inserted into the outer side of the limiting rod 25, and the core barrel 26 is leveled so that one side of it is in contact with the side of the limiting disk. Then, the rotating wheel 29 is reversed to cause the screw rod 27 to drive the conical block 28 to move, so that the conical block 28 can enter the through hole. Then, the rotating wheel 29 continues to be rotated to press the core barrel 26 tightly, and fix the core barrel 26 under the restriction of the limiting disk. Then, the motor 22 is started to make the driving wheel 23 drive the driven wheel 24 to rotate. When the driven wheel 24 rotates, the limiting rod 25 can drive the core barrel 26 to rotate, and then the lithium battery diaphragm can be rolled up. After the rolling is completed, the rotating wheel 29 is rotated to separate the conical block 28 from the core barrel 26, so that the core barrel 26 can be removed.

[0027] The working principle of the semi-automatic winding equipment for lithium battery production provided by the utility model is as follows:

[0028] When in use, the lithium battery diaphragm is passed between the two sets of guide rollers 6 and the cutting frame 31, and connected to the winding mechanism 2, and then the winding mechanism 2 is started to start winding the lithium battery diaphragm. After winding, the cutting mechanism 3 is started to automatically cut the lithium battery diaphragm, thereby improving work efficiency. When the cutter 34 is damaged, the cutter 34 can be removed through the installation mechanism 4 for easy replacement.
