Description

Technical Field

[0001] This utility model relates to the field of lithium battery copper foil technology, specifically a winding mechanism for an integrated lithium battery copper foil machine. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board. As a conductor in the PCB, it easily adheres to the insulating layer, receives the printed protective layer, and forms the circuit pattern after etching. Lithium-ion battery copper foil is one of the important materials for lithium batteries. During the production process, lithium-ion battery copper foil needs to be wound up and collected by a winding mechanism for convenient subsequent transportation and use.

[0003] For example, a winding mechanism for an integrated lithium battery copper foil machine (Announcement No.: CN221587470U) uses a control box to activate a plug-in limit component, which, in conjunction with a connection limit component, conveniently and stably connects the core tube to the motor for transmission. Disassembly is easy by simply activating the plug-in limit component through the control box. This solves the problem that existing winding mechanisms require disassembling and moving the roll tube during use, which is inconvenient for moving the wound lithium battery copper foil. In practice, fixing the roll tube is difficult, making disassembly and movement of the roll tube inconvenient and affecting the winding of the lithium battery copper foil, thus reducing the effectiveness of the winding mechanism.

[0004] While the device allows for relatively easy disassembly of the coil, the lack of a support mechanism at the bottom of the coil leads to decreased stability as the weight of the copper foil increases during operation. This poses a risk of tilting or even falling, increasing safety hazards during device use. Therefore, we need to propose a winding mechanism for an integrated lithium battery copper foil machine.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A winding mechanism for a lithium battery copper foil integrated machine includes a base frame 1, a vertical plate 2, two sets of winding mechanisms 3, two sets of guiding mechanisms 4, and two sets of supporting mechanisms 5. The vertical plate 2 is fixedly installed on the top of the base frame 1. The two sets of guiding mechanisms 4 guide the copper foil of the two sets of winding mechanisms 3 during operation. The two sets of winding mechanisms 3 are symmetrically arranged above the base frame 1, and the two sets of guiding mechanisms 4 are symmetrically arranged on one side of the vertical plate 2, with the two sets of guiding mechanisms 4 located above the two sets of winding mechanisms 3.

[0027] It also includes a drive mechanism 6, which drives the two sets of support mechanisms 5 to move, making it easy to disassemble and assemble the winding mechanism 3.

[0028] In this embodiment, the two sets of winding mechanisms 3 can simultaneously perform winding operations on copper foil, realizing dual-station operation, which greatly improves work efficiency. After winding is completed, the support mechanism 5 can be moved by the drive mechanism 6 to separate the winding mechanism 3, and the wound copper foil can be removed, which is relatively simple and convenient.

[0029] The drive mechanism 6 includes a threaded rod 61, a first motor 62, and two sets of limiting rods 63. The threaded rod 61 is rotatably installed inside the base frame 1. One end of the threaded rod 61 passes through the base frame 1 and is connected to the first motor 62. The two sets of limiting rods 63 are symmetrically fixed inside the base frame 1 to limit the support mechanism 5.

[0030] In this embodiment, the output end of the first motor 62 drives the threaded rod 61 connected to it to rotate, and the support mechanism 5 is limited by two sets of limiting rods 63, so that the support mechanism 5 can move when the threaded rod 61 rotates.

[0031] Both sets of support mechanisms 5 include a movable plate 51, two sets of support plates 52 and two sets of auxiliary parts 53. Both sets of movable plates 51 are threadedly connected to the outer wall of the threaded rod 61, and both sets of movable plates 51 are slidably installed on the outer wall of the two sets of limit rods 63.

[0032] In this embodiment, the driving mechanism 6 causes the two sets of moving plates 51 to move, the moving plates 51 drive the two sets of support plates 52 connected to them to move, and the support plates 52 drive the auxiliary parts 53 connected to them to move. Through the cooperation of multiple sets of auxiliary parts 53, the winding mechanism 3 can be separated.

[0033] Two sets of support plates 52 are symmetrically fixedly installed on the top of the movable plate 51, and two sets of auxiliary parts 53 are respectively fixedly connected to the top of the two sets of support plates 52. The auxiliary parts 53 are attached to the winding mechanism 3 to support the winding mechanism 3.

[0034] In this embodiment, the auxiliary component 53 is attached to the winding mechanism 3, so that the support mechanism 5 can support the winding mechanism 3, which can improve the stability of the winding mechanism 3 and prevent the winding mechanism 3 from tilting or even falling due to the increase in its mass during operation, thus reducing the safety hazards when using the device.

[0035] The auxiliary component 53 includes an arc-shaped frame 531, two sets of mounting slots, and two sets of auxiliary wheels 532. The two sets of auxiliary wheels 532 are rotatably mounted on the arc-shaped frame 531 through the two sets of mounting slots.

[0036] In this embodiment, when the winding mechanism 3 is working, it will drive the auxiliary wheel 532 to rotate inside the mounting groove. The auxiliary wheel 532 can support the winding mechanism 3 without affecting its operation, and the support effect is good.

[0037] Both sets of winding mechanisms 3 include a winding roller 31, a connecting piece 32, a drive shaft 33, and a second motor 34. The second motor 34 is fixedly installed on one side of the vertical plate 2. One end of the drive shaft 33 is connected to the output end of the second motor 34, and the other end of the drive shaft 33 passes through the vertical plate 2 and is fixedly connected to the connecting piece 32. The drive shaft 33 is rotatably installed on the vertical plate 2 through a bearing, and the winding roller 31 is installed on one end of the connecting piece 32.

[0038] In this embodiment, the output end of the second motor 34 drives the transmission shaft 33 connected to it to rotate, the transmission shaft 33 drives the connector 32 connected to it to rotate, thereby causing the winding roller 31 to rotate, so as to realize the winding operation of copper foil.

[0039] One end of the take-up roller 31 is provided with a connecting groove 35 that is adapted to the connector 32. One end of the connector 32 is inserted into the inside of the connecting groove 35, and both ends of the take-up roller 31 are in contact with the support mechanism 5.

[0040] In this embodiment, the connection of the connector 32 and the connecting groove 35 enables the quick loading and unloading of the take-up roller 31, and both ends of the outer wall of the take-up roller 31 are in contact with the auxiliary wheel 532 to support the take-up roller 31 and improve its stability.

[0041] Both sets of guiding mechanisms 4 include a guide rod 41, two sets of limiting discs 42 and a rotating rod 43. The rotating rod 43 is rotatably mounted on one side of the vertical plate 2 via a bearing. The two sets of limiting discs 42 are respectively fixedly mounted at both ends of the guide rod 41 to limit the copper foil. One end of the rotating rod 43 is connected to one of the limiting discs 42.

[0042] In this embodiment, the two sets of guiding mechanisms 4 guide the copper foil when the two sets of winding mechanisms 3 are working. The guide rod 41 supports the copper foil and can provide the tension required when the copper foil is wound. The two sets of limiting discs 42 can limit the copper foil to ensure the direction of movement of the copper foil and prevent the copper foil from tilting. When the copper foil moves, it comes into contact with the guide rod 41. By providing a rotating rod 43, the guide rod 41 can drive the rotating rod 43 to rotate on one side of the vertical plate 2 to ensure the normal movement of the copper foil.

[0043] It is worth noting that the specific working principle and circuit connection of the motor, which are well known to those in the field, will not be elaborated on here. The first motor 62 can be a Panasonic MINASA6 series MSMA052P1G model motor, which has the characteristics of high-precision positioning. The second motor 34 can be a Siemens 1FT7 series 1FT7064-5AF71-1DG0 model motor, which has the advantages of constant tension winding control and support for regenerative braking.

[0044] Working principle: When this utility model is in use, the support mechanism 5 is provided. When the winding mechanism 3 is working, the winding roller 31 will drive the auxiliary wheel 532 in contact with it to rotate. The auxiliary wheel 532 can support the winding roller 31 without affecting its operation, thereby improving the stability of the winding roller 31 and preventing the winding roller 31 from tilting or even falling due to its increased weight during operation, thus reducing the safety hazards when using the device.
