Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal electrolytic metallurgy technology, and in particular to an adaptive nickel cathode stripping station and stripping method. Background Technology

[0002] Electrolysis is one of the main methods for obtaining high-purity non-ferrous metal materials. In nickel production, the pure nickel product produced through electrolysis is simply referred to as "electrolytic nickel" in the industry. During the electrolytic refining or electrowinning of nickel, nickel ions are deposited on the surface of the cathode plate to form nickel starter sheets or finished nickel plates. Due to the strong adhesion between nickel metal and the cathode plate (especially the seed plate or permanent cathode) substrate, how to completely and undamagedly peel the nickel sheets from the cathode plate has always been a pressing technical problem in the industry. Currently, the industry commonly uses manual prying or simple mechanical clamping and pulling for nickel sheet peeling. This method has drawbacks such as harsh working environment, high labor costs, severe product damage, and significant cathode plate wear.

[0003] With the development of automation technology, some large smelting enterprises have begun to try using robotic stripping stations. However, existing stripping stations typically use rigid suction cups or simple gripper mechanisms, which are difficult to adapt to the warping deformation of the cathode plate during use and the uneven thickness of the nickel deposits, resulting in poor adsorption reliability and low stripping success rate. In addition, existing stripping stations are often single-function, only able to complete the stripping operation, lacking effective integration with upstream and downstream processes, making it difficult to form continuous automated production.

[0004] Therefore, there is an urgent need for an automated stripping station with adaptive adsorption capacity, high stripping success rate, and good integration with upstream and downstream processes, in order to improve the overall equipment level and economic benefits of nickel electrolysis production. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an adaptive nickel cathode stripping station and stripping method.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An adaptive nickel cathode stripping station includes: Station frame; Two pulley propulsion mechanisms are mounted on the station frame, one on the left and one on the right. Two trolley frames are respectively mounted on the propulsion ends of two trolley propulsion mechanisms; A support frame is installed on the station frame and located between two trolley frames, on which the cathode plate is placed; Two suction cup holders are connected to the trolley frame via connecting hinges; An adaptive suction cup mechanism is mounted on the suction cup holder; The adaptive suction cup mechanism includes: Several suction cup components arranged in an array; Each suction cup assembly has a guide rod at its tail, which is inserted into the suction cup frame. The tail of the guide rod is connected to the suction cup frame through an elastic floating element.

[0007] The trolley frame is also equipped with a positioning and clamping mechanism, which is located at the front end of the adaptive suction cup mechanism; The positioning and clamping mechanism includes: The chuck has a square frame structure, and its two sides are slidably connected to the trolley frame. The locating pin is located on the top of the chuck and can be inserted into the locating groove on the cathode plate lifting lug. The clamping drive unit is mounted on the trolley frame, and its telescopic end is connected to the chuck.

[0008] The clamping drive unit is cylinder II, and the telescopic rod of cylinder II is connected to the chuck through fisheye connector II.

[0009] The cylinder II is mounted on the trolley frame (7) via a fixing bracket.

[0010] The adaptive suction cup mechanism further includes: The piston cylinder is located at the bottom of the trolley frame, and its piston rod is connected to the bottom of the suction cup frame, allowing the suction cup frame to swing back and forth.

[0011] The trolley propulsion mechanism includes: Cylinder I is located at the rear of the station frame, and its telescopic end is connected to the trolley frame via a connector. Guide rails are installed on the track frames on both sides of the upper part of the station frame; The slider is mounted on the trolley frame via a slider mounting block, and the slider is slidably connected to the guide rail.

[0012] The telescopic end of cylinder I is connected to the trolley frame connector via fisheye connector I.

[0013] The present invention also provides an adaptive nickel cathode stripping method, comprising the following steps: S1. The trolley propulsion mechanism drives the positioning clamping mechanism and the adaptive suction cup peeling mechanism to move synchronously toward the cathode plate. S2. The positioning and clamping mechanism contacts the cathode plate and performs positioning and clamping. S3, Adaptive suction cup peeling mechanism, which makes each suction cup component contact the surface of the nickel sheet and adsorbs the nickel sheet after close contact through a dual adaptive mechanism. S4. The trolley propulsion mechanism moves backward, while the adaptive suction cup peeling mechanism gradually lifts the suction cup assembly in a preset sequence, so that the nickel sheet is peeled off from the cathode plate. S5. The trolley propulsion mechanism continues to move backward, transferring the stripped nickel sheet to the top of the nickel sheet collection mechanism and releasing the nickel sheet; S6. The positioning clamping mechanism is released, and the trolley propulsion mechanism is reset.

[0014] The beneficial effects of this invention are: First, it features a compact structure and coordinated operation. By integrating the positioning and clamping mechanism and the adaptive suction cup peeling device onto the same trolley propulsion mechanism, synchronous advance and retreat of the two are achieved, simplifying the equipment structure and control logic. The entire process of approach, positioning, peeling, and resetting can be completed with only one main propulsion power, thus improving work efficiency.

[0015] Secondly, the peeling success rate is high. The adaptive suction cup peeling device effectively compensates for errors such as cathode plate deformation and uneven nickel sheet surface through a dual mechanism of macroscopic floating of elastic floating elements and microscopic adaptive adjustment of suction cup frame drive unit. This ensures that each suction cup can be tightly attached to the nickel sheet surface, guaranteeing uniform and reliable adsorption force and greatly improving the peeling success rate.

[0016] Third, protect the product and the cathode plate. A gradual peeling method is adopted, that is, as the trolley retracts, the suction cup frame drive unit retracts in a preset sequence, so that the nickel sheet is gradually separated from the cathode plate like tearing tape. This avoids tearing, deformation or damage to the cathode plate caused by sudden forceful pulling, ensuring the integrity of the product and the reusability of the cathode plate.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0019] like Figures 1 to 3 As shown, an adaptive nickel cathode stripping station includes: a station frame 1; two trolley propulsion mechanisms 2, one on the left and one on the right, mounted on the station frame 1; two trolley frames 7, respectively mounted on the propulsion ends of the two trolley propulsion mechanisms 2; a support frame 21, mounted on the station frame 1 and located between the two trolley frames 7, on which a cathode plate 19 is placed; two suction cup frames 13, connected to the trolley frames 7 by connecting hinges 27; and an adaptive suction cup mechanism 4, mounted on the suction cup frames 13. The adaptive suction cup mechanism 4 includes: a plurality of arrayed suction cup assemblies 16; wherein each suction cup assembly 16 has a guide rod 14 at its tail, the guide rod 14 is inserted into the suction cup frame 13, and the tail of the guide rod 14 is connected to the suction cup frame 13 by an elastic floating element 15. The trolley frame 7 is also equipped with a positioning and clamping mechanism 3, which is located at the front end of the adaptive suction cup mechanism 4. The positioning and clamping mechanism 3 includes: a clamp 9, which is a square frame structure and is slidably connected to the trolley frame 7 on both sides; a positioning pin 12, which is located on the top of the clamp 9 and can be inserted into the positioning groove 11 on the lifting lug of the cathode plate 19; and a clamping drive unit 10, which is located on the trolley frame 7 and whose telescopic end is connected to the clamp 9. The clamping drive unit 10 is a cylinder II 26, and the telescopic rod of the cylinder II 26 is connected to the clamp 9 through a fisheye connector II 24. The cylinder II 26 is mounted on the trolley frame 7 through a fixing bracket 22. The adaptive suction cup mechanism 4 also includes: a piston cylinder 18, which is located at the bottom of the trolley frame 7, and its piston rod 17 is connected to the bottom of the suction cup frame 13, so that the suction cup frame 13 can swing back and forth. The trolley propulsion mechanism 2 includes: a cylinder I 25, located at the tail of the station frame 1, with its telescopic end connected to the trolley frame 7 via a connector; a guide rail 6, located on the track frames 8 on both sides of the upper part of the station frame 1; and a slider 5, mounted on the trolley frame 7 via a slider mounting block 28, with the slider 5 slidably connected to the guide rail 6. The telescopic end of the cylinder I 25 is connected to the connector of the trolley frame 7 via a fisheye joint I 23.

[0020] Specifically, Example 1: Figure 1-3As shown, guide rail 6 is laid horizontally on track frame 8, and trolley frame 7 is slidably mounted on guide rail 6. The propulsion drive unit uses cylinder I25, which drives trolley frame 7 to reciprocate along guide rail 6. Positioning clamping mechanism 3 and adaptive suction cup peeling device 4 are both fixedly mounted on the same trolley frame 7 to achieve synchronous advance and retreat. Adaptive suction cup peeling device 4 includes suction cup frame 13, guide rod 14, elastic floating element 15, multiple suction cup assemblies 16 and piston cylinder 18.

The trolley propulsion mechanism 2 continues to move forward a small distance, the suction cup frame 13 contacts the nickel sheet 20, and the compressed elastic floating element 15 achieves overall floating adhesion. Subsequently, the suction cup assembly 16 independently adheres to the surface of the nickel sheet 20. The pneumatic control system initiates vacuum adsorption, and all suction cup assemblies 16 adsorb the nickel sheet 20. The trolley propulsion mechanism 2 retracts, causing the nickel sheet 20 to gradually peel off from the cathode plate 19. The trolley propulsion mechanism 2 continues to retract above the nickel sheet collection mechanism, and the pneumatic control system releases the nickel sheet 20. The positioning and clamping mechanism 3 releases, the trolley propulsion mechanism 2 resets, and one work cycle is completed.

S4. The trolley propulsion mechanism 2 moves backward, and at the same time the adaptive suction cup peeling mechanism 4 gradually lifts the suction cup assembly 16 in a preset sequence, so that the nickel sheet 20 is peeled off from the cathode plate 19. S5. The trolley propulsion mechanism 2 continues to retreat, transferring the stripped nickel sheet 20 to the top of the nickel sheet collection mechanism and releasing the nickel sheet 20. S6. Positioning clamping mechanism 3 is released, and trolley propulsion mechanism 2 is reset.
