The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Figure 1-2 The diagram shows the structure of the double-sided electrode outlet positioning platform when the electrode tab plate 200 is fed in the outer electrode outlet mode. The double-sided electrode outlet positioning platform is mounted on the frame 100 and is used to support the electrode tab plate 200 which moves in the X direction. It includes a support platform 10 extending in the X direction and baffle plates 20 and push plates 30 respectively located on both sides of the support platform 10 in the Y direction and extending in the X direction. The baffle plates 20 and push plates 30 can be installed on the front side or the rear side of the support platform 10 in the Y direction respectively and can move towards or away from each other under the action of external force to clamp or release the electrode tab plate 200 on the support platform 10. Wherein: The frame 100 is provided with a first slide rail 1 extending in the Y direction. A baffle plate 20 and a pusher plate 30 are mounted on the first slide rail 1. The baffle plate 20 has an L-shaped structure, and a support platform 10 is detachably fixed on its transverse wall. One Y-direction end of the support platform 10 extends to the outside of the baffle plate 20 and to the side of the pusher plate 30. The pusher plate 30 is connected to the first drive device 40 on the frame 100 and can be translated along the Y direction under its drive to approach or move away from the support platform 10. The frame 100 is also provided with a second slide rail 4 extending in the Y direction. A slider 5 is mounted on the second slide rail 4. A first drive device 40 is mounted on the slider 5, and the slider 5 is connected to the second drive device 70 via a second transmission device 60, allowing it to slide along the second slide rail 4 under the drive of the second drive device 70. This drives the first drive device 40 to move synchronously in the Y direction. The first drive device 40 is connected to the pusher plate 30 via a transmission plate 6. In this embodiment, the first drive device 40 is a cylinder, the second drive device 70 is a knob, and the second transmission device 60 is a screw-nut transmission pair. Manually rotating the knob pushes the slider 5 to slide in the second slide rail 4 via the screw-slider transmission pair, causing the second drive device 40 to move synchronously in the Y direction, thereby pushing the pusher plate 30 to the appropriate position.

[0021] In this embodiment, the first slide 1 is composed of several slide rails arranged in the X direction and extending along the Y direction. The X-direction end of the support platform 10 is also provided with a vacuum adsorption positioning component 80, which is used to adsorb the tab plate 200 onto the support platform 10.

[0022] During operation, the feeding mechanism drives the tab plate 200 to move horizontally along the X direction on the support table 10. When it reaches the processing station, the first driving device 40 drives the pusher plate 30 to move horizontally along the Y direction, pushing the tab plate 200 onto the baffle plate 20 for positioning. After completion, the air pump applies negative pressure and fixes the tab plate 200 on the support table 10 through the adsorption positioning component 80 connected to it to ensure the processing accuracy of the tab.

[0023] like Figure 1 As shown, the baffle plate 20 includes a pad 21 and a baffle plate 22. The pad 21 is mounted on the first slide rail 1 and extends in the X direction. The baffle plate 22 is detachably fixed on it and extends in the Z direction. A support platform 10 is detachably fixed on the pad 21 on the side of the baffle in the Y direction. The pad 21 is detachably fixed on the frame 100 through a positioning plate 2. The support platform 10 is also provided with a scale 50 extending in the Y direction. An indicator plate 3 is provided on the side of the scale 50. The indicator plate 3 is detachably fixed on the baffle plate 20 or the pusher plate 30. In this embodiment, both the positioning plate 2 and the indicator plate 3 are L-shaped structures.

[0024] like Figure 1-2 As shown, the pusher plate 30 includes a mounting plate 31 and a plurality of push rods 32. The mounting plate 31 is mounted on the first slide rail 1 and extends in the X direction. The plurality of push rods 32 are arranged on the mounting plate 31 in the X direction and all extend in the Y direction. Each push rod 32 has an elastic element 33 at its end facing the support table 10.

[0025] During installation, first fix the support platform 10 onto the pad 21, then fix the baffle 22 onto the pad 21 and position it to the side of the support platform 10 in the Y direction. Then fix the positioning plate 2 and the indicator plate 3 onto the side wall of the pad 21 and / or the baffle 22 away from the support platform. Next, place the pad 21 on the first slide rail 1 and slide it along it until the indicator plate 3 points to the set position on the scale 50. Use locking screws to lock and fix the other end of the positioning plate 2 and the indicator plate 3 onto the frame 100. After completion, place the mounting plate 31 with the push rod 32 on the first slide rail 1 and fix it on the transmission plate 6.

[0026] Figure 3-4This diagram illustrates the structure of the double-sided electrode positioning platform when the electrode sheet 200 is fed inwards. It shows that when the electrode sheet 200 is fed inwards, simply remove the pad 21 with the baffle 22 from one side of the support platform 10 in the Y direction and fix it to the other side in the Y direction. Remove the mounting plate 31 with the push rod 32 from the transmission plate 6. Start the second drive device 70, move the first drive device 40 to an appropriate position, and move the transmission plate 6 to an appropriate position on the other side of the support platform 10 in the Y direction. Finally, quickly fix the mounting plate 31 to the positioning plate 6. The scale 50, in conjunction with the indicator plate 3, can quickly move the push plate 30 to the set position. The entire disassembly and adjustment process does not require disassembling the internal structure of the positioning platform, making operation convenient and quick. It can effectively meet the needs of rapid positioning of electrode sheets with different sizes and feeding methods within a certain range in production, reducing production time losses and costs, and improving production efficiency.

[0027] This application also provides a lithium battery winding machine, including a positioning platform, which is the dual-sided tab positioning platform in the above embodiment.

[0028] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
