Description

Technical Field

[0001] This invention relates to the field of integrated technology of non-ferrous metal metallurgy, and in particular to a zinc sheet stripping device based on a blade-type cathode plate. Background Technology

[0002] Currently, in electrolytic deposition production, the target metal is periodically deposited on the surface of the cathode plate. Once the deposited layer reaches the specified thickness, it needs to be peeled off from the cathode plate in a stable, rapid, low-damage, and low-deformation manner, followed by subsequent processes such as cleaning, conveying, stacking / weighing / packaging, and motherboard return.

[0003] Regarding the zinc stripping process, based on a field survey of the zinc stripping production line at Yunnan Jinding Zinc Industry, the existing technology uses a rapping method to create an initial separation gap (pre-stripping process) from the cathode plate before the zinc sheet is stripped (main stripping process). However, the rapping process is unstable, making it difficult to form an effective initial separation gap at the zinc sheet-cathode plate interface, thus failing to create an effective pre-opening. This results in significant difficulties in subsequent zinc sheet stripping and a low success rate. Current technology divides the zinc stripping process into two steps: the pre-stripping process and the main stripping process. The transition between these two steps requires manual intervention, disrupting the continuity of the zinc stripping process. Furthermore, these processes are complex, have low overall production efficiency, increase labor costs and operational safety hazards, and rigidly restrict the improvement of equipment automation levels. Summary of the Invention

[0004] This invention provides a zinc sheet stripping device based on a blade-type cathode plate. Existing technologies suffer from the following problems: they cannot form an effective pre-opening, making subsequent zinc sheet stripping difficult and resulting in a low success rate; the process is complex, disrupting the continuity of zinc sheet stripping work, leading to low overall production efficiency; and they also increase labor costs and operational safety hazards, creating a rigid constraint on improving the level of equipment automation.

[0005] To address the aforementioned problems, the present invention provides the following technical solution:

[0006] A zinc sheet stripping device based on a blade-type cathode plate includes a frame on which a clamping assembly is mounted. The clamping assembly drives a blade to move to or away from the injection molding area of ​​the cathode plate. The clamping assembly clamps the blade onto the cathode plate or releases the blade from the cathode plate.

[0007] Optionally, the clamping assembly includes two sets of motion components mounted on the frame. An upper jaw and a lower jaw are respectively mounted on the two sets of motion components. The motion components drive the upper jaw and the lower jaw to move, so that the upper jaw and the lower jaw can clamp the tool.

[0008] Optionally, each set of motion components includes a lead screw rotatably mounted on the frame, a lead screw with a lead screw nut mounted on it, a stepper motor mounted on the top of the frame, the output shaft of the stepper motor connected to the lead screw nut, and the upper gripper or the lower gripper mounted on the lead screw nut.

[0009] Optionally, the clamping assembly includes guide assemblies mounted on both sides of the frame, and two sets of motion assemblies located between the two sets of guide assemblies; each set of guide assemblies includes a gripper guide rail mounted on the frame, a slider slidably mounted on the gripper guide rail, the slider being connected to the nut connector, and the upper gripper or the lower gripper being mounted on the connector.

[0010] Optionally, the clamping assembly includes a clamping fixture and a clamping fixture, which are mounted on the cathode plate and clamp the tool on the cathode plate.

[0011] Optionally, the clamping fixture and the clamping clamp are rotatably mounted on the cathode plate, and a compression spring is installed between the upper part of the clamping fixture and the cathode plate, and a compression spring is installed between the upper part of the clamping clamp and the cathode plate.

[0012] Optionally, the clamping assembly further includes a cylinder mounted on the frame, the output end of the cylinder being connected to a push rod, the push rod being able to press or release the upper part of the clamping fixture.

[0013] Optionally, a push rod guide rail can be detachably mounted on the frame, and a push rod is slidably mounted on the push rod guide rail.

[0014] Optionally, the push rod is provided with a pressing part.

[0015] Optionally, a hook guide rail is installed on the top of the frame, and a hook is slidably installed on the hook guide rail to lift the cathode plate.

[0016] The above technical solution has at least the following advantages compared with the existing technology:

[0017] The zinc sheet stripping device of the present invention, as described above, fixes the cutting tool to the cathode plate, fundamentally abandoning the traditional process route that relies on rapping to achieve initial separation. Before the zinc electrolytic deposition process begins, the cutting tool is precisely installed in a preset position on the cathode plate, causing the zinc layer, originally deposited above the injection molding area and with a thickness of 3-5 mm, to be deposited on the surface of the cutting tool. This significantly simplifies the complex processes of pre-stripping and main stripping in the traditional process. Only two core operations—cutting tool placement and zinc sheet stripping—need to be completed on the production line to achieve reliable separation of the zinc sheet from the cathode plate. The process is simple, reducing the cycle time by more than 60%, resulting in high overall production efficiency. The entire zinc sheet stripping process is unmanned, eliminating labor costs and operational safety hazards, thus solving the continuity and stability problems of the traditional process from the source. Furthermore, it reduces the overall complexity of the system in principle, avoiding the operational instability caused by randomness in the traditional process.

[0018] The zinc sheet stripping device of the present invention can effectively protect the injection molding area with the blade, preventing it from being damaged in the subsequent brushing process, extending the service life of the cathode plate, reducing equipment replacement and maintenance costs, and further improving the economic benefits and input-output ratio of the production line.

[0019] The stripping device of the present invention consists of a clamping assembly, a clamping assembly, and a cutting tool. The various parts work together to realize the fully automated operation of the zinc stripping process. It realizes the reliable fixation and tight fit of the cutting tool on the cathode plate, as well as the automatic gripping and stripping function of the cutting tool during the production process, freeing operators from highly repetitive and frequently intervened manual labor.

[0020] The clamping and fastening components of the zinc sheet stripping device of the present invention are simple in design and can be assembled by conventional fastening methods such as welding and bolt connection, without the need for special processing technology and special equipment.

[0021] The zinc stripping device of the present invention does not require the scrapping or re-customization of the entire cathode plate. It only requires a small investment in the material and processing costs of connectors and cutting tools. The modification cost of a single cathode plate is controllable and economical.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that the terms "up", "down", "left", "right", "front", and "back" used in this invention are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0041] like Figure 1 , Figure 2 and Figure 4As shown, this embodiment provides a zinc sheet 8 stripping device based on a blade-type cathode plate for zinc stripping operations on an electrolytically deposited cathode plate 1. Under dynamic and harsh working conditions, it can automatically strip the zinc sheet from the surface of the cathode plate 1. It can also be applied to copper and nickel stripping. The zinc sheet 8 stripping device includes a frame 10, on which a clamping assembly is mounted. The clamping assembly drives a blade 6 to move, moving the blade 6 to or away from the injection molding area 7 of the cathode plate 1. The clamping assembly clamps or releases the blade 6 from the cathode plate 1. Figure 13 As shown, the cutter 6 has a T-shaped structure, including a handle 61 and a cutting edge 62. In this embodiment, before the zinc electrolytic deposition process begins, the zinc sheet 8 peeling device moves the cutter 6 to the injection molding area 7 of the cathode plate 1 via a clamping assembly, and the clamping assembly clamps the cutter 6 and the cathode plate 1. During the zinc electrolytic deposition process, the zinc sheet 8 is deposited and adhered to the surface of the cutter 6 and the cathode plate 1 (the area below the cutter 6). Since the cutter 6 and the injection molding area 7 of the cathode plate 1 are clamped, the zinc sheet 8 will not be deposited on the injection molding area 7 of the cathode plate 1. After the zinc electrolytic deposition process is completed, the clamping assembly releases the cutter 6 and the cathode plate 1, and the clamping assembly drives the cutter 6 to move downward. The cutter 6 peels off the zinc sheet 8 deposited in the area below the cutter 6 on the cathode plate 1. At the same time, the zinc sheet 8 on the cutter 6 is detached from the cutter 6. The clamping assembly moves the cutter 6 back to the injection molding area 7 of the cathode plate 1, and the clamping assembly clamps the cutter 6 onto the cathode plate 1. The cathode plate 1 is then transported to the next zinc electrolytic deposition process. In this embodiment, the cutting tool 6 and the injection molding area 7 of the cathode plate 1 are tightly fitted together through the working surface of the clamping assembly, ensuring that there is no obvious gap at the bonding interface during the electrolytic deposition stage, effectively avoiding the accidental deposition of zinc layer on the back side of the cutting tool 6, and ensuring the integrity and reliability of subsequent zinc stripping operations.

[0042] like Figure 1 and Figure 6As shown, the clamping assembly includes two sets of motion components and two sets of guide components mounted on the frame 10. The two sets of guide components are respectively mounted on both sides of the frame 10, and the two sets of motion components are located between the two sets of guide components. The two sets of motion components drive the upper jaw 18 and the lower jaw 19 to move, respectively, and the upper jaw 18 and the lower jaw 19 clamp the tool 6. The two sets of guide components guide the movement of the upper jaw 18 and the lower jaw 19. Each set of motion components includes a lead screw 14 rotatably mounted on the frame 10, with a lead screw nut 24 mounted on the lead screw 14. A stepper motor 9 is mounted on the top of the frame 10, and the output shaft of the stepper motor 9 is connected to the lead screw nut 24. The upper jaw 18 or the lower jaw 19 is mounted on the lead screw nut 24. Each set of guide components includes a jaw guide rail 11 mounted on the frame 10. Specifically, the upper and lower parts of the jaw guide rail 11 have countersunk holes, and the jaw guide rail 11 is fixed to the frame 10 through these countersunk holes and bolt fasteners. A slider 25 is slidably mounted on the gripper guide rail 11. The slider 25 is connected to the nut 24 via a connector 30. An upper gripper 18 or a lower gripper 19 is mounted on the connector 30. Specifically, the nut 24, slider 25, and connector 30 are welded into a single unit, and the upper gripper 18 or lower gripper 19 is detachably mounted on the connector 30 using bolts. In this embodiment, the slider 25 and gripper guide rail 11 adopt the existing linear gripper guide rail structure, which will not be described further in this application.

[0043] In this embodiment, the stepper motor 9 starts, the lead screw 14 rotates, the lead screw 14 rotates and drives the lead screw nut 24 to move, the lead screw nut 24 moves and drives the upper jaw 18 or the lower jaw 19 to move through the connector 30. During the above movement, the slider 25 slides on the jaw guide rail 11, the upper jaw 18 and the lower jaw 19 move closer to each other, and the upper and lower jaws respectively clamp the upper and lower ends of the tool 6, clamping the tool 6.

[0044] like Figure 1 , Figure 4 , Figure 5 , Figure 7As shown, this embodiment has two sets of clamping assemblies, located on both sides of the cathode plate 1. Each clamping assembly includes a clamping fixture 3 and a clamping fixture 5, which are mounted on the cathode plate 1 and clamp the tool 6 on the cathode plate 1. Specifically, the clamping fixture 3 and clamping fixture 5 are rotatably mounted on the cathode plate 1. Compression springs 2 are installed between the upper part of the clamping fixture 3 and the upper part of the clamping fixture 5 and the cathode plate 1. Preferably, this embodiment has two clamping fixtures 3 and one clamping fixture 5, with the two clamping fixtures 3 located on both sides of the clamping fixture 5. The two ends of the compression spring 2 are welded to the clamping fixture 3 and the cathode plate 1, and the two ends of the compression spring 2 are welded to the clamping fixture 5 and the cathode plate 1. The upper part of the clamping fixture 3 has a circular groove 33, and the compression spring 2 is connected within the circular groove 33. The clamping fixture 3 has a first through hole 31, and the clamping fixture 5 has a second through hole 51. A protrusion is provided on the cathode plate 1, and a rotating shaft 4 is mounted on the protrusion. The first through hole 31 of the clamping fixture 3 is rotatably mounted on the rotating shaft 4, and the second through hole 51 of the clamping fixture 5 is rotatably mounted on the rotating shaft 4. In this embodiment, the lower part of the clamping fixture 3 has a first clamping part 32, which is a rectangular protruding structure (e.g., ...). Figure 8 (as shown) or other protruding structures, the lower part of the clamping fixture 5 is provided with a second clamping part 52, the second clamping part 52 is a sloping protruding structure (such as... Figure 9 (As shown) or other protruding structures of different shapes. The clamping assembly includes a cylinder 16, which is mounted on the frame 10. The output end of the cylinder 16 is connected to a push rod 17, which has a pressing part 171. The pressing part 171 of the push rod 17 can press or release the upper part of the clamping fixture 3 and the clamping fixture 5. Specifically, the cylinder 16 is bolted to the intermediate beam of the frame 10. The output end of the cylinder 16 is a flange 161, which has four countersunk holes. The countersunk holes are connected to the push rod 17 by bolt fasteners. A push rod guide rail 21 is detachably mounted on the frame 10. The push rod 17 is slidably mounted on the push rod guide rail 21. The push rod guide rail 21 and the push rod 17 form a linear guide rail. The linear guide rail adopts the linear guide rail of the prior art, which will not be described in detail in this application. Specifically, countersunk holes are opened at both ends of the push rod guide rail 21, and the countersunk holes are connected to the frame 10 by bolt fasteners.

[0045] In this embodiment, the cylinder 16 is activated, and the cylinder 16 pushes the push rod 17 to move towards the cathode plate 1. During this process, the push rod 17 slides in the push rod guide rail 21. The pressing part 171 of the push rod 17 presses the upper part of the clamping fixture 3 and the clamping fixture 5. The compression spring 2 is in a compressed state. The clamping fixture 3 and the clamping fixture 5 rotate around the rotating shaft 4 in a direction away from the cathode plate 1. The clamping part of the lower part of the clamping fixture 3 and the clamping part of the lower part of the clamping fixture 5 moves away from the cathode plate 1. The clamping part of the lower part of the clamping fixture 3 and the clamping fixture 5 no longer clamps the tool 6 and the cathode plate 1, and the tool 6 and the cathode plate 1 are released. When cylinder 16 is activated, it pushes push rod 17 to move away from cathode plate 1. During this process, push rod 17 slides within push rod guide rail 21. The pressing part 171 of push rod 17 moves away from the upper part of clamping fixture 3 and clamping fixture 5. Compression spring 2 returns to normal state. The clamping parts of the lower part of clamping fixture 3 and clamping fixture 5 clamp the tool 6 and cathode plate 1.

[0046] like Figure 2 As shown, in this embodiment of the zinc sheet 8 peeling device, the top hook guide rail 13 of the frame 10 has a hook 12 slidably mounted on the hook guide rail 13, and the hook 12 lifts the cathode plate 1. The cathode plate 1 is made of aluminum, the blade 6 is made of 88% alumina ceramic, and the injection molding area 7 is made of polyurethane. The zinc sheet 8 peeling device in this embodiment is equipped with a fence 22 on the outside.

[0047] like Figure 1 and Figure 2 As shown, the zinc sheet 8 stripping device in this embodiment includes a controller 23, which is electrically connected to a stepper motor 9, a cylinder 16, and a proximity switch 34. The proximity switch 34 is installed on the hook guide rail 13. After the hook 12 lifts the cathode plate 1 to the target position, the proximity switch 34 sends a position signal to the controller 23. Upon receiving the position signal, the controller 23 controls the stepper motor 9 and the cylinder 16 to start, and the zinc sheet 8 stripping device begins to work.

[0048] The working process of the zinc sheet stripping device based on the blade-type cathode plate in this embodiment is as follows:

[0049] Before the zinc electrolytic deposition process begins, the stepper motor 9 of the clamping assembly is started, and the upper jaw 18 and lower jaw 19 move closer to each other, clamping the upper and lower ends of the tool 6 respectively. The cylinder 16 of the clamping assembly is started, and the push rod 17 presses the upper part of the clamping fixture 3 and clamping fixture 5. The lower part of the clamping fixture 3 and clamping fixture 5 moves away from the cathode plate 1. The tool 6 moves to the injection area 7 of the cathode plate 1 through the lead screw 14 and lead nut 24 of the clamping assembly. The push rod 17 moves away from the upper part of the clamping fixture 3 and clamping fixture 5, and the clamping part of the lower part of the clamping fixture 3 and clamping fixture 5 clamps the tool 6 and the cathode plate 1. During the above process, the back side of the clamping fixture 3 and clamping fixture 5 (clamping fixture 3 and clamping fixture 5) Compression springs 2, which are in a pre-compressed state, are fixed on the side near the cathode plate 1. The compressive force generated by the compression springs 2 is converted into a horizontal clamping force by the lever mechanism (the upper part of the clamping fixture 3 and the clamping fixture 5, the rotating shaft 4 and the clamping part of the lower part of the clamping fixture 3 and the clamping fixture 5 form a lever mechanism), which acts on the tool 6 (the tool holder 61 part of the tool 6) and locks the tool 6 to the surface of the cathode plate 1. The horizontal clamping force of the clamping fixture 5 located in the middle is focused on the contact interface between the tool 6 and the injection molding area 7. This clamping force forces the tool 6 to press against the injection molding area 7, causing the injection molding area 7 to produce a slight elastic deformation, so as to achieve a tight fit between the end of the tool 6 and the cathode plate 1, effectively preventing the zinc sheet 8 from adhering to the back side of the tool 6 during the deposition process.

[0050] During the zinc electrolytic deposition process, zinc sheet 8 is deposited and adhered to the surface of tool 6 and cathode plate 1 (the area located below tool 6). Since tool 6 and cathode plate 1 are clamped together, zinc sheet 8 will not be deposited on injection area 7 of cathode plate 1.

[0051] After the zinc electrolytic deposition process is completed, the deposited cathode plate 1 is transported from the electrolytic deposition process to the zinc stripping process by the hook 12. The stepper motor 9 of the clamping assembly is started, and the upper and lower jaws respectively clamp the upper and lower ends of the cutter 6, clamping the cutter 6. The cylinder 16 of the clamping assembly is started, and the push rod 17 presses the upper part of the clamping fixture 3 and the clamping fixture 5. The clamping part of the lower part of the clamping fixture 3 and the clamping fixture 5 is separated from the cutter 6, and the cutter 6 is no longer clamped to the cathode plate 1. The clamping assembly drives the cutter 6 to move downward, peeling off the zinc sheet 8 on the cathode plate 1.

[0052] Start the stepper motor 9 of the clamping assembly, move the tool 6 to the injection area 7 of the cathode plate 1, start the cylinder 16 of the clamping assembly, clamp the tool 6 on the cathode plate 1, and the cathode plate 1 is transported to the next zinc electrolytic deposition process by the hook 12.

[0053] In this embodiment, the blade 6 is closely attached to the surface of the cathode plate 1, thereby preventing zinc from adhering to the back side of the blade 6 during the electrolytic deposition process and ensuring the effectiveness of subsequent zinc stripping operations.

[0054] like Figure 9 and Figure 10 As shown, in the clamping state, the compression spring 2 is compressed and provides a preset clamping force. This spring force acts on the upper part of the clamping fixture 3 and is converted into a horizontal clamping force acting on the tool holder 61 of the tool 6 via a lever transmission mechanism. Under the combined action of the horizontal clamping force and its own weight, the tool 6 generates corresponding reaction forces at the cathode plate 1 and the rotating shaft 4. Considering the material properties, the injection molding area 7 is equivalent to a damping element.

[0055] Based on this, we can introduce the assumption of small-angle deformation: under the action of spring force, the rotation angle of clamping fixture 3 is small, satisfying... Relationship. Let the angle of rotation about the revolute joint be the angle between the positions of the compression spring 2 and the clamping fixture 3. Then the deformation displacement of the compression spring 2 is:

[0056]

[0057] in Location such as Figure 9 As shown, this is the distance between the top of the upper part of the clamping fixture 3 and the rotating joint.

[0058] According to Hooke's Law, the elastic force generated by compressing spring 2 can be calculated as follows:

[0059]

[0060] in is the spring constant of compression spring 2.

[0061] The torque generated by the elastic force on the rotating joint is:

[0062]

[0063] Based on the above torque balance relationship, the motion differential equation of clamping fixture 3 is established as follows:

[0064]

[0065] in Let be the moment of inertia of the clamping fixture 3.

[0066] like Figure 9 and Figure 10 As shown, in this embodiment, the shank 61 of the cutting tool 6 is fixed to the cathode plate 1 by the clamping fixture 3, and the clamping force generated by the compression spring 2 The force transmitted through the lever transmission mechanism and acting on the cutting edge 62 surface of the tool 6 can be deduced based on the lever balance principle:

[0067]

[0068] in and Location such as Figure 9 As shown, these represent the distances between the bottom of the clamping fixture 3 and the rotating joint, and the distances between the bottom of the clamping fixture 3 and the contact points between the cutting tool and the injection molding area.

[0069] This model also adopts the above assumption of small-angle deformation.

[0070] Let the angle of rotation of the contact position between the cutter 6 and the injection molding area 7 about the rotating joint be... angular velocity is Then the linear velocity at that position for:

[0071]

[0072] Based on damping characteristics, the damping force generated in the injection molding zone It can be represented as:

[0073]

[0074] in This is the damping coefficient of the injection molding zone.

[0075] The damping force generates a damping torque on the rotating pair. for:

[0076]

[0077] At the same time, the clamping fixture 5 applies force External torque applied to the rotating joint for:

[0078]

[0079] Substituting the torque equilibrium condition into... From the expression, the motion differential equation of clamping fixture 5 can be established as follows:

[0080]

[0081] in The moment of inertia of clamping fixture 5.

[0082] To verify whether the proposed structure can reliably mount the tool 6 on the cathode plate 1 and ensure a tight fit between the tool 6 and the surface of the cathode plate 1, static simulation analysis was performed using ANSYS.

[0083] The boundary conditions are set as follows: a fixed constraint is applied to the cathode plate 1, restricting all its degrees of freedom, so that it remains stationary during the simulation.

[0084] To simplify the model, the force of the compression spring 2 is equivalent to a concentrated force, and a clamping force of 50N is applied to both the clamping fixture 3 and the clamping fixture 5 to simulate the preload effect of the compression spring 2. At the same time, standard Earth's gravitational acceleration is applied throughout the model to reproduce the effect of gravity under actual working conditions.

[0085] The equivalent stress distribution at point 61 of the tool holder is calculated as follows: Figure 11 As shown in the figure, the equivalent stresses measured at the two probe positions are 0.10994 MPa and 0.10758 MPa, respectively, which are 1-2 orders of magnitude higher than those in other areas. This result indicates that the designed clamping fixture 3 can reliably fix and position the tool on the cathode plate.

[0086] The equivalent stress at the contact point between the cutting tool 6 and the injection molding area, and the equivalent stress at the contact point between the cutting tool tip and the cathode plate, are as follows: Figure 12 As shown.

[0087] Analysis of the data from each probe location revealed a certain equivalent stress in the injection molding area, indicating that the tool 6 causes slight elastic deformation in this area during clamping. Simultaneously, significant equivalent stress was observed at the contact point between the tip of the tool 6 and the cathode plate 1, indicating a relatively tight fit between them. Further analysis revealed that the stress value at the location of the clamping fixture 5 was much higher than that of the mounting fixture itself. This difference suggests that the clamping fixture 5 plays a dominant role in enhancing the tightness of the fit between the tool and the cathode plate.

[0088] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
