Abstract
Description
Technical Field
[0001] The utility model relates to a lifting and positioning device, in particular to a passivation tank lifting and positioning device suitable for a copper foil passivation process, and belongs to the technical field of copper foil manufacturing. Background Art
[0002] Copper foil refers to a foil made of copper and with a thickness of less than 100μm. Copper foil is mainly used in copper-clad laminates or printed circuit boards (attached to the substrate to provide excellent conductivity and electromagnetic shielding) and lithium batteries (as the negative electrode of the anode current collector). The manufacturing methods of copper foil include calendering and electrolysis. Among them, the electrolysis method is widely used because of its easy production, high efficiency and low cost. The main processes for manufacturing copper foil by electrolysis include solution foil production, surface treatment and product slitting. The copper foil generated by the foil production machine is wound on the winding roller to form the original foil. The original foil is then subjected to surface treatments such as roughening layer treatment, heat-resistant layer treatment, anti-oxidation layer treatment and finally product slitting according to product requirements to obtain the copper foil product.
[0003] Since copper foil is very thin, it is inevitable that the copper foil will tear, be oxidized, have scratches, and have inconsistent color during the actual production of the original copper foil. Production workers need to first remove the defective copper foil from the equipment, and then manually thread the foil. The copper foil peeled off from the cathode roller of the foil machine will be passed around the various levels of redirecting rollers of the equipment in turn, and connected to the winding roller. Since the original foil is thin and wide, manual foil threading usually requires multiple people to work together carefully to avoid tearing. In the process of manual foil threading, the front and rear sections of the equipment have large operating spaces and are easy to operate, but the middle sections, especially the passivation section located behind the washing station and in front of the drying station, usually have narrow spaces. In addition, the passivation step usually forms an anti-oxidation film on the surface of the copper foil by immersion electroplating, that is, the copper foil is submerged below the liquid level of the electroplating solution in the passivation tank during the process of being transported by the redirecting roller located above the passivation tank. The electroplating process is completed after the copper foil passes through the passivation tank. Therefore, it is difficult to manually thread the foil in the passivation section, and it is extremely inconvenient for multiple people to operate together. Summary of the invention
[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a passivation tank lifting and positioning device, which can greatly reduce the difficulty of manual foil penetration in the passivation working section and facilitate equipment maintenance.

[0006] The lifting mechanism comprises a lifting actuator, the lifting end of the lifting actuator drives the passivation tank to lift, and the base end of the lifting actuator is fixedly connected to the frame;
[0007] The positioning mechanism comprises a positioning execution component and a positioning structure. The positioning execution component comprises a telescopic rod installed in cooperation with the positioning structure. The positioning structure is fixed at the front end of the telescopic rod. The positioning structure is used to support the passivation tank body after jacking.
[0008] As a further improvement of the utility model, a lifting platform is fixedly provided at the bottom of the passivation tank, the lifting end of the lifting actuator drives the lifting platform to rise and fall, and the positioning actuator is arranged on the frame.

The positioning structure of the positioning mechanism includes a positioning pad fixedly connected to the end of the telescopic rod of the positioning actuator, and the positioning pad is used to support the passivation trough after jacking.
[0012] As a preferred solution of the utility model, the lifting actuator is a vertically arranged cylinder.

[0014] As another implementation manner of the utility model, a handle is fixedly connected to the rear end of the positioning execution component, and the positioning execution components on the same side of the frame are connected to the same handle.
[0015] Compared with the prior art, the passivation tank lifting and positioning device, when performing normal passivation work of the copper foil, firstly controls the lifting execution component to lift the passivation tank, and then controls the movement of the telescopic rod of the positioning execution component to position the passivation tank. At this time, the lower end roller surfaces of the active redirecting roller and the driven redirecting roller are submerged below the liquid level of the electroplating solution in the passivation tank, and the copper foil is submerged below the liquid level of the electroplating solution when passing through the active redirecting roller and the driven redirecting roller to achieve electroplating; in the state of manual foil wearing or maintenance, the passivation tank can be placed in a non-positioning state by first controlling the resetting action of the telescopic rod of the positioning execution component, and then the passivation tank is lowered by controlling the lifting execution component.

The lifting end of the lifting actuator 31 is installed and connected with the passivation tank 2, and the base end of the lifting actuator 31 is fixedly installed and connected with the frame 1. By controlling the action of the lifting actuator 31, the lifting action of the passivation tank 2 relative to the frame 1 can be controlled; the positioning mechanism 4 includes a positioning actuator The row component 41 and the positioning structure arranged in cooperation, the positioning structure can be a positioning shaft arranged on the frame 1 (or the passivation trough 2) and a positioning hole structure arranged in cooperation on the passivation trough 2 (or the frame 1), or it can be a positioning pad arranged on the frame 1 (or the passivation trough 2) and other positioning structures such as a positioning table arranged in cooperation on the passivation trough 2 (or the frame 1). The positioning execution component 41 includes a telescopic rod installed in cooperation with the positioning structure. After the passivation trough 2 is raised by controlling the lifting execution component 31, the positioning execution component 41 can be controlled by controlling the action of the telescopic rod to achieve the positioning of the passivation trough 2 by controlling the positioning structure.
[0022] like Figure 1 , Figure 2 As shown, the notch of the passivation tank body 2 is arranged upward, and the active redirecting roller 11, the driven redirecting roller 12 and the pressure roller 13 arranged in parallel are installed in a rolling cooperation manner at the position corresponding to the position just above the notch of the passivation tank body 2 on the frame 1, the active redirecting roller 11 of the redirecting roller driving mechanism is transmission-connected with the driven redirecting roller 12, the roller surface of the pressure roller 13 is in contact with the roller surface of the active redirecting roller 11, the copper foil is redirected and transported by the active redirecting roller 11, the driven redirecting roller 12 and the pressure roller 13, and the passivation tank body 2 is provided with an electroplating solution. In the working state, the passivation tank body 2 is first raised by controlling the lifting actuator 31, and then the passivation tank body 2 is positioned by controlling the action of the telescopic rod of the positioning actuator 41. At this time, the roller surfaces of the active redirecting roller 11 and the driven redirecting roller 12 at the lower end are submerged below the liquid level of the electroplating solution of the passivation tank body 2, and the copper foil is submerged below the liquid level of the electroplating solution when passing through the active redirecting roller 11 and the driven redirecting roller 12 to achieve electroplating. In the state of manual foil wearing or maintenance, the passivation tank body 2 can be placed in a non-positioning state by first controlling the resetting action of the telescopic rod of the positioning actuator 41, and then the passivation tank body 2 can be lowered by controlling the lifting actuator 31. At this time, the active redirecting roller 11 and the driven redirecting roller 12 located directly above the passivation tank body 2 are in a state of being away from the passivation tank body 2, and there is an operating space between the active redirecting roller 11 and the driven redirecting roller 12 and the passivation tank body 2, which is convenient for manual foil wearing and equipment maintenance.
[0023] In order to facilitate the installation of the lifting mechanism 3 and the positioning mechanism 4, as a further improvement scheme of the utility model, a lifting platform 21 is fixedly provided at the bottom of the passivation trough 2, the lifting end of the lifting actuator 31 is installed and connected to the lifting platform 21, and the positioning actuator 41 can be set on the frame 1 or on the lifting platform 21.
[0024] In order to improve the stability of the lifting action, as a further improvement of the utility model, a lifting guide mechanism 5 is further provided between the frame 1 and the passivation tank body 2.

After the passivation tank body 2 is lifted by the cylinder and the lifted passivation tank body 2 is positioned by the positioning mechanism 4, the cylinder can be controlled to reset and the telescopic end can be separated from the passivation tank body 2 without maintaining pressure and leaning against the passivation tank body 2.
[0027] The telescopic movement of the telescopic rod of the positioning actuator 41 can be controlled manually or automatically. When the automatic control method is adopted, the telescopic rod of the positioning actuator 41 also includes a telescopic drive component. The telescopic drive component can be a telescopic cylinder structure such as a cylinder or a hydraulic cylinder, or other linear reciprocating motion structures such as a screw nut structure provided in conjunction with the telescopic drive component. The telescopic movement of the telescopic rod of the positioning actuator 41 is controlled by controlling the movement of the telescopic drive component. When the manual control method is adopted, the rear end of the telescopic rod of the positioning actuator 41 can be fixedly connected with a handle 43. The positioning actuator 41 on the same side of the frame 1 is connected to the same handle 43.
