Description

Technical Field

[0001] The invention belongs to the technical field of pole piece threading, and relates to a pole piece threading device, in particular to a pole piece fast threading device. Background Art

[0002] With the application and popularization of lithium batteries in society, lithium-ion batteries are not only widely used in consumer electronic products, but also highly valued in the power battery market for electric vehicles and industrial energy storage. Therefore, the market demand is expanding, and the production capacity and efficiency of manufacturers must be gradually improved. In the production of lithium batteries, the process of unwinding and rewinding the pole sheet material roll is involved. The initial work of this process is threading, which is to wind the pole sheet onto the roller in turn, and then perform other work. However, the threading process is complicated, and the pole sheet is easy to break. Therefore, the threading of the pole sheet is a major problem that plagues all manufacturers.

[0003] In the prior art, manufacturers still rely mainly on manual threading, which passes through the first guide roller, the over roller, and the second guide roller in sequence. When threading, the pole piece needs to be manually transferred from unwinding to rewinding. This process requires at least two people to cooperate with each other, one to transfer at the entrance and one to pick up and deliver at the exit, and to adjust repeatedly so that the pole piece passes through all the workstations. Because the whole process requires at least two people to transfer and deliver the pole piece on the roller up and down and left and right, it is not only inefficient, but also extremely easy to cause problems such as wrinkles and breaks of the pole piece. And because the threading process is extremely difficult, it will also cause the production line to shut down for a long time, reduce production efficiency, and reduce production capacity, which is not conducive to market competition. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the present invention aims to provide a device for quickly threading a pole piece, so as to achieve the purpose of automatic threading, improving work efficiency, increasing production capacity, saving labor, and high-quality pole piece threading.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A pole piece fast threading device, comprising a bracket, a guide rail arranged along the length direction of a first guide roller, a driving device for driving the pole piece to move forward and bypass the first guide roller, and a lifting device fixed on the bracket for moving the guide rail in a direction close to or away from the first guide roller, wherein the driving device is slidably connected to the guide rail;

[0007] The bracket is fixed with a changeable material guide plate that allows the pole piece to bypass the first guide roller and change from a horizontal direction to a vertical upward movement, the bracket is fixed with a first vertical material guide plate and a second vertical material guide plate that allows the pole piece to move vertically upward, the bracket is fixed with a first gas nozzle that sprays gas in a horizontal direction and allows the pole piece that moves vertically upward to bypass the roller and change to a vertical downward movement, the bracket is fixed with a discharge plate that allows the pole piece to bypass the second guide roller and change from a vertical downward movement to a horizontal movement, and the first vertical material guide plate and the second vertical material guide plate are located on both sides of the pole piece;

[0008] The bracket is fixed with a second gas nozzle for ejecting gas moving upward and making the pole piece transition from the changeable material guide plate to the first vertical material guide plate. The first gas nozzle and the second gas nozzle are both connected to an air pump for generating gas through a pipeline.

[0009] As a limitation of the present invention: the driving device is provided with two along the guide rail, including a mounting frame, a rotating wheel rotatably connected to the mounting frame, and a motor fixed on the mounting frame for driving the rotating wheel to rotate; the mounting frame is slidably connected to the guide rail.

[0010] As a further limitation of the present invention: a groove is provided on the guide rail, a convex block matching with the groove is provided on the mounting frame, and a limiting device for limiting the position of the mounting frame is fixed on the mounting frame.

[0011] As a further limitation of the present invention: the limiting device includes a threaded hole provided on the mounting frame and a fixing bolt passing through the threaded hole and abutting against the groove.

[0012] As another limitation of the present invention: the lifting device is a cylinder, and two cylinders are provided and are respectively located at two ends of the guide rail.

[0013] As a further limitation of the present invention: a side of the changeable material guide plate close to the first guide roller is a curved surface adapted to the first guide rail, and a side of the discharge plate close to the second guide roller is a curved surface adapted to the second guide roller.

[0014] As a third limitation of the present invention: the first gas nozzle is a flat nozzle, and the second gas nozzle is a 90-degree nozzle.

[0015] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0016] (1) A guide rail is arranged under the first guide roller of the present invention, and a driving device is slidably connected to the guide rail. The driving device can guide the pole piece. The pole piece is placed on the driving device so that the pole piece moves forward along the roller. The driving device can slide on the guide rail and can adjust the position of the driving device at any time to make it better adapt to the width of the pole piece. The lifting device on the guide rail can adjust the position of the guide rail so that the gap between the guide rail and the roller can be adjusted arbitrarily. It can adapt to pole pieces of different thicknesses and has strong versatility. The guide plate makes the pole piece rotate from the horizontal direction to the vertical direction along with the driving device, and continues to move upward under the buoyancy of the gas ejected by the first gas nozzle. After passing through the gap between the first vertical guide plate and the second vertical guide plate, the movement is changed to the horizontal direction under the horizontal force of the gas ejected by the second gas nozzle. After passing through the roller, it naturally droops and enters the discharge plate for discharge, completing the belt threading, eliminating manual operation and reducing labor costs. The driving device drives the pole piece to move, avoiding problems such as wrinkles and breakage of the pole piece due to the roller being too long during manual operation. The belt threading speed is fast, the work efficiency is high, the belt threading time is saved, and the production capacity is improved;

[0017] (2) The pole piece of the present invention is provided with a driving device on both sides, and the driving device includes a motor and a rotating wheel. The motor drives the rotating wheel to rotate, and the pole piece is placed on the rotating wheel and moves forward with the rotation of the rotating wheel. The motor can make the rotation speed of the two rotating wheels the same, so that the movement speed of both sides of the pole piece is the same, which can effectively avoid the problem of wrinkling and breaking of the pole piece during the threading process. In addition, the motor and the rotating wheel can slide on the guide rail with the mounting frame, so that it can adapt to pole pieces of different widths, and the adjustment is convenient and fast;

[0018] (3) The guide rail of the present invention is provided with a groove, and the protrusion on the mounting frame slides in the groove, and the mounting frame can be fixed at any position on the guide rail through a limiting device, so that it is firmly fixed, the structure is ingenious, and the operation is simple;

[0019] (4) The limiting device of the present invention includes a bolt, which passes through the mounting frame and abuts against the groove of the guide rail. The limiting device is simple and stable, the operation is fast, and the processing cost is saved;

[0020] (5) The lifting device of the present invention is a cylinder, which is easy to control, quick to move, and not easy to damage;

[0021] (6) The direction-changing guide plate and the discharge plate of the present invention both have one side that is an arc surface, so that they are adapted to the first guide roller and the second guide roller respectively, so that the pole pieces can smoothly transition during the reversing process without scratching the pole pieces or generating resistance, thereby facilitating the reversing of the pole pieces.

[0022] In summary, the present invention has an ingenious structure, is easy to control, easy to operate, saves threading time, saves labor costs, has high threading efficiency, does not cause damage to the pole piece, and is suitable for threading all pole pieces.

DETAILED DESCRIPTION

[0027] The preferred embodiment of the present invention is described below in conjunction with the accompanying drawings. It should be understood that the pole piece fast threading device described herein is a preferred embodiment, which is only used to illustrate and explain the present invention and does not constitute a limitation of the present invention.

[0028] Embodiment Pole piece fast threading device

[0029] In this embodiment, Figure 1 , Figure 2 As shown, a pole piece fast threading device includes a bracket 16, a guide rail 4, a driving device 5 and a lifting device. The pole piece fast threading device of this embodiment is suitable for the existing guide roller device in the prior art, such as Figure 1 As shown, the guide roller device includes a first guide roller 1, a roller 2 disposed on the upper left of the first guide roller 1, and a second guide roller 3 disposed below the roller 2. The first guide roller 1 is located below, and the roller 2 is located above the first guide roller 1. A gap is formed between the vertical tangent on the left side of the first guide roller 1 and the vertical tangent on the right side of the roller 2 for the pole piece 15 to pass through. During the threading process of the pole piece 15, the pole piece 15 needs to be passed around the first guide roller 1, the roller 2, and the second guide roller 3 in sequence.

[0030] The guide rail 4 is in the shape of an elongated strip and is arranged along the length direction of the first guide roller 1. A groove 8 is provided on the guide rail 4. The cross section of the groove 8 is an isosceles trapezoid, which is wider at the top and narrower at the bottom.

[0031] There are two driving devices 5, both of which are slidably connected to the guide rail 4. The driving device 5 includes a mounting frame 51, a motor 53 fixed on the mounting frame 51, and a rotating wheel 54 fixed on the motor shaft of the motor 53. The mounting frame 51 is provided with a bottom plate and three vertical plates arranged perpendicular to the bottom plate, wherein the rotating wheel 54 is rotatably connected between the gaps of two vertical plates, and the motor 53 is fixed on the third vertical plate, and the motor 53 is connected to the rotating wheel 54 through a coupling 55 to drive the rotating wheel 54 to rotate. The mounting frame 51 is provided with a protrusion 52 that matches the groove 8, and the mounting frame 51 is slidably connected to the groove 8 along with the protrusion 52. Because the upper part of the groove 8 is wide and the lower part is narrow, the protrusion 52 will not be separated from the groove 8 from the upper part, preventing the mounting frame 51 from being taken out. The mounting frame 51 is fixed with a limiting device, which includes a threaded hole on the mounting frame 51 and a fixing bolt 6 passing through the threaded hole and abutting against the groove 8. After adjusting the position of the mounting frame 51, the fixing bolt 6 is passed through the threaded hole so that it abuts against the bottom surface of the groove 8, which can prevent the mounting frame 51 from moving along the length direction of the guide rail 4. The cooperation between the protrusion 52 and the groove 8 is used to limit the up and down movement of the mounting frame 51 along the guide rail 4, and the fixing bolt 6 is used to limit the movement of the mounting frame 51 along the length direction of the guide rail 4, so that the mounting frame 51 can be accurately fixed to a position suitable for the width of the pole piece 15. By adjusting the position of the mounting frame 51, it is adapted to the width of the pole piece 15, so that it can adapt to pole pieces 15 of different widths.

[0032] Both ends of the guide rail 4 are fixedly provided with a lifting device, which is a cylinder 7. Both ends of the guide rail 4 are fixedly connected to the telescopic rod of the cylinder 7 through an L-shaped plate. The cylinder 7 is fixedly provided on a bracket 16, and the guide rail 4 is provided below the first guide roller 1. The lifting of the cylinder 7 drives the guide rail 4 to move in a direction close to or away from the first guide roller 1, so that a good spacing is maintained between the guide rail 4 and the first guide roller 1, which is convenient for the pole piece 15 to pass through.

[0033] The bracket 16 is provided with a guide plate 9 for changing the direction of the pole piece 15 from horizontal to vertical upward around the first guide roller 1. Figure 1 As shown, the deflecting guide plate 9 is two plates arranged perpendicular to each other, one of which is located below the first guide roller 1, and the other is located to the left of the first guide roller 1. The two plates are close to the first guide roller 1 on one side through a transition through an arc panel to form an arc surface for matching the curvature of the first guide roller 1. An opening for a rotating wheel 54 to pass through is provided on the plate below the first guide roller 1, so that the uppermost tangent of the rotating wheel 54 is located above the opening, so that the pole piece is driven by the rotating wheel 54 to transition to the deflecting guide plate 9. When in use, the pole piece 15 to be threaded is placed on the rotating wheel 54. As the rotating wheel 54 rotates, the pole piece 15 moves along the arc of the deflecting guide plate 9, changing from horizontal movement to vertical movement.

[0034] The bracket 16 is fixedly provided with a first vertical guide plate 10 and a second vertical guide plate 11. The first vertical guide plate 10 is located directly above the changeable guide plate 9 and is tightly connected to the changeable guide plate 9. The second vertical guide plate 11 is located on the right side of the first vertical guide plate 10 and forms a gap with the first vertical guide plate 10 for the pole piece 15 to pass through. The roller 2 is located above the first vertical guide plate 10. The end of the second vertical guide plate 11 away from the changeable guide plate 9 is flush with the roller 2, so as to attach the pole piece 15 to the roller 2. The bracket 16 is fixedly provided with a first gas nozzle 13. The first gas nozzle 13 is a flat nozzle that can spray gas moving in a horizontal direction, so that the pole piece 15 moving vertically upward to the end of the second vertical guide plate 11 can move horizontally around the roller 2 and change to a vertical downward movement along the surface of the roller 2.

[0035] The bracket 16 is fixedly provided with a second gas nozzle 14, which is located at the position of the variable-direction material guide plate 9 and is arranged on the left side of the first guide roller 1. The second gas nozzle 14 is a 90-degree nozzle, which can generate vertically upward gas, so that the pole piece 15 transitions from the variable-direction material guide plate 9 to the first vertical material guide plate 10 and then continues to move upward. The first gas nozzle 13 and the second gas nozzle 14 are both connected to an air pump 17 for generating gas through a pipeline.

[0036] The bracket 16 is fixed with a discharge plate 12, the inner side of which is an arc surface adapted to the second guide roller 3. After the pole piece 15 comes out from the roller 2, it naturally droops due to gravity, and then moves to the arc surface of the discharge plate 12, bypassing the second guide roller 3 and changing from vertical downward movement to horizontal movement.

[0037] In the working process of this embodiment, the pole piece 15 to be threaded is placed on the rotating wheel 54. Driven by the motor 53, the pole piece 15 moves forward by the friction between the rotating wheel 54 and the first guide roller 1. As the curved surface of the guide plate 9 changes from horizontal to vertical, the second gas nozzle 14 generates gas in a vertical direction. Under the action of air flotation, the pole piece 15 continues to move vertically upward along the gap formed by the first vertical guide plate 10 and the second vertical guide plate 11. When it moves to the end of the second vertical guide plate 11, The first gas nozzle 13 generates horizontal gas, which changes the vertically upward moving pole piece 15 into horizontal movement. The pole piece 15 attached to the surface of the roller 2 continues to move along the surface of the roller 2. After bypassing the roller 2, it naturally droops down by gravity and moves to the discharge plate 12. As the arc surface of the discharge plate 12 bypasses the second guide roller 3, it is finally output in the horizontal direction, completing the threading of the pole piece 15. Under the friction between the rotating wheel 54 and the first guide roller 1, the pole piece 15 continues to move until it is output in the horizontal direction. The whole process only needs to be monitored manually.

[0038] The directional terms or positional relationships such as "upper", "lower", "left" and "right" described in the present invention are based on the drawings in the present invention specification. Figure 1 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.
