Description

Technical Field

[0001] This utility model relates to the field of battery electrode manufacturing technology, and in particular to a feeding unit for an electrode slitting machine. Background Technology

[0002] The battery electrode sheets are pressed to the specified specifications by a pressure roller machine, cut according to the specific requirements of the battery, and finally wound into rolls by a fully automatic winding device.

[0003] When the electrode enters the feeding unit of the slitting machine, in order to prevent deviation on both sides of the electrode, a correction actuator is set at the feeding end of the slitting machine. The correction actuator controls the left and right position of the probe through a servo motor to find the edges on both sides of the electrode. After positioning, it stops moving. If the edges on both sides of the electrode are not within the detection range of the probe, it proves that the electrode has deviated, and feedback is sent to the actuator for correction.

[0004] However, during the electrode feeding process, due to the long distance between the upper and lower guide rollers, the two sides of the electrode often vibrate. This causes the probe to be unable to accurately detect the edge position of the two sides of the electrode, thus sending incorrect information to the correction actuator for correction.

[0005] Therefore, when the electrode enters the slitting machine, the edges on both sides of the electrode need to be smoothed to ensure that the two sides of the electrode are in a stable state so that the probe can accurately detect the edge positions on both sides of the electrode. Summary of the Invention

[0006] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a feeding unit for an electrode slitting machine to effectively prevent the electrode from shaking on both sides and ensure that the electrode enters the slitting machine smoothly.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a feeding unit for an electrode slitting machine is provided between two wall plates on the left and right sides of the feeding end of the slitting machine. It includes a fixed frame fixed between the upper ends of the wall plates. A movable frame is provided below the fixed frame, which can be driven by an electric cylinder to rotate around the center of one side of the fixed frame. A front correction roller is rotatably installed between the two ends of the front side of the movable frame, and a rear correction roller is rotatably installed between the two ends of the rear side of the movable frame. A guide aluminum roller is rotatably installed between the wall plates located below the front correction roller. The electrode to be slitting passes through the rear correction roller and the front correction roller and then enters the guide aluminum roller vertically. A detection mechanism is provided between the wall plates close to the front correction roller. The detection mechanism has ultrasonic sensors respectively provided on the left and right sides of the front correction roller to detect the left and right edge positions of the electrode. A horizontal spreading component is provided on the bottom surface of the ultrasonic sensor. The horizontal spreading component has a horizontal spreading wheel that fits against the front edge position of the electrode to prevent the electrode from shaking.

[0008] Specifically, the horizontal extension assembly includes a pair of right-angle brackets arranged left and right along the axis of the horizontal extension wheel. The horizontal plate of the right-angle bracket is fixed to the bottom surface of the ultrasonic sensor, and a horizontal bracket is fixed to the outer side of the bottom of the vertical plate of the right-angle bracket. The horizontal extension wheel is rotatably installed between the horizontal brackets, and a connecting plate is fixed between the vertical plates of the right-angle bracket.

[0009] Furthermore, a follower assembly is provided between the four corners of the fixed frame and the four corners of the moving frame. The follower assembly includes an upper corner plate fixed to the fixed frame, a lower corner plate fixed to the moving frame, an arc-shaped guide rail fixed to the upper corner plate, and a follower wheel. The arc-shaped guide rail has an arc-shaped groove with the center of the arc pointing to the center of the fixed frame. The follower wheel slides in conjunction with the arc-shaped groove. A support is fixed on the lower corner plate. The follower wheel is threadedly connected to the support through an integral threaded shaft.

[0010] To adjust the detection position of the ultrasonic sensor, the detection mechanism includes a back plate fixed between the wall panels, and roller screws that drive the ultrasonic sensor to move left and right are respectively provided at both ends of the back plate.

[0011] Specifically, the back plate is fixed with a bearing seat that rotates and supports the ball screw, a nut seat is sleeved on the ball screw, a screw nut that drives the ball screw is installed in the nut seat, a right-angle seat is fixed on the upper end face of the nut seat, and the ultrasonic sensor is installed on the right-angle seat.

[0012] Furthermore, a handwheel seat is fixed on the back plate, and a handwheel is rotatably mounted on the handwheel seat. A bevel gear reducer is provided at the lower end of the handwheel shaft. A small bevel gear, which serves as the driving gear of the bevel gear reducer, is machined at the lower end of the handwheel shaft. The small bevel gear meshes with and drives a large bevel gear. The shaft end of the roller screw is fixedly connected to the inner hole of the large bevel gear.

[0013] The beneficial effects of this utility model are: by setting a horizontal spreading component on the bottom surface of the ultrasonic sensor, and using the horizontal spreading wheel to fit the front edge of the electrode, this utility model prevents the edges of the electrode from shaking during the process of vertically entering the front correction roller from the guide aluminum roller, thereby ensuring that the ultrasonic sensor can accurately detect the edge positions of the two sides of the electrode.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figure 1 , Figure 2 , Figure 4 The electrode sheet slitting machine feeding unit shown is located between two wall panels 1 on the left and right sides of the feeding end of the slitting machine. It includes a fixed frame 2 in the shape of a rectangle fixed between the upper ends of the two wall panels 1. A movable frame 3 is provided below the fixed frame 2. A front straightening roller 4 is rotatably installed between the two front ends of the movable frame 3. A rear straightening roller 5 is rotatably installed between the two rear ends of the movable frame 3. A guide aluminum roller 6 is rotatably installed between the wall panels 1 located below the front straightening roller 4. The electrode sheet 7 to be slitting passes through the rear straightening roller 5 and the front straightening roller 4 and then enters the guide aluminum roller 6 vertically.

[0024] See Figure 3As shown, follower components 50 are respectively provided between the four corners of the fixed frame 2 and the four corners of the moving frame 3. The follower components 50 include an upper corner plate 13 fixed to the fixed frame 2, a lower corner plate 14 fixed to the moving frame 3, an arc-shaped guide rail 15 fixed to the upper corner plate 13, and a follower wheel 16. The arc-shaped guide rail 15 has an arc-shaped groove 17 with the arc center pointing to the center of the fixed frame 2. The follower wheel 16 slides with the arc-shaped groove 17. A support 18 is fixed on the lower corner plate 14. The follower wheel 16 is threadedly connected to the support 18 through an integral threaded shaft.

[0025] An electric cylinder is installed between the fixed frame 2 and the moving frame 3. The mounting end of the electric cylinder is fixed on the fixed frame 2, and the power end of the electric cylinder is connected to the moving frame 3. Through the extension and retraction of the electric cylinder, when correction is needed, the moving frame 3 is pushed to rotate left or right around the center of one side of the fixed frame 2, which drives the front correction roller 4 and the rear correction roller 5 to rotate synchronously, so as to correct the deviation generated on both sides of the electrode sheet 7.

[0026] See Figure 5 As shown, a detection mechanism 30 is provided between the two wall plates 1 close to the lower part of the front correction roller 4. The detection mechanism 30 has ultrasonic sensors 8 respectively located at the left and right ends of the front correction roller 4 to correspond to the left and right edge positions of the detection electrode 7.

[0027] Specifically, the testing mechanism 30 includes a back plate 19 fixed between two wall panels 1. Two bearing seats 21 are fixed on the back plate 19 and spaced apart. A roller screw 20 is rotatably mounted between the bearing seats 21. A nut seat 22 is sleeved on the roller screw 20. A screw nut that drives the roller screw 20 is installed in the nut seat 22. A right-angle seat 23 is fixed on the upper end face of the nut seat 22. The ultrasonic sensor 8 is mounted on the right-angle seat 23.

[0028] A handwheel seat 24 is fixed on the back plate 19. A handwheel 25 is rotatably mounted on the handwheel seat 24. A bevel gear reducer 27 is provided at the lower end of the handwheel shaft 26 of the handwheel 25. A small bevel gear, which serves as the driving gear of the bevel gear reducer 27, is machined at the lower end of the handwheel shaft 26. The small bevel gear meshes with and drives a large bevel gear. The shaft end of the roller screw 20 is fixedly connected to the inner hole of the large bevel gear.

[0029] By turning the handwheel 25, the bevel gear reducer 27 drives the roller screw 20 to rotate and engage with the screw nut in the nut seat 22, thereby driving the ultrasonic sensor 8 to move to the left or right to adjust the position of the ultrasonic sensor 8 and accurately detect the edge positions on both sides of the electrode 7.

[0030] The bottom surface of the ultrasonic sensor 8 is provided with a transverse assembly 40, see [link / reference] Figure 6As shown, the horizontal spreading assembly 40 includes a pair of right-angle brackets 10 arranged left and right at a distance. The horizontal plate of the right-angle bracket 10 is fixed to the bottom surface of the ultrasonic sensor 6. Horizontal brackets 11 are fixed to the outer side of the bottom of the vertical plate of the right-angle bracket 10. A horizontal spreading wheel 9 is rotatably installed between the horizontal brackets 11. A connecting plate 12 is fixed between the vertical plates of the right-angle bracket 10. When the slitting machine feeds the material, the horizontal spreading wheel 9 is in contact with the front edge of the electrode 7 to prevent the edges of the electrode 7 from shaking during the process of vertically entering the front correction roller 4 from the guide aluminum roller 6, so as to ensure that the ultrasonic sensor 8 can accurately detect the edge positions of the electrode 7.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
