Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment in copper electrolysis process, and specifically relates to an auxiliary positioning device for preventing damage to the cathode motherboard. Background Technology

[0002] In the process of producing high-purity cathode copper through permanent stainless steel cathode electrolysis, a stripping unit is indispensable for removing the cathode copper. Currently, cathode stripping units generally use the method of flexing the cathode copper to detach the deposited cathode copper from the stainless steel plate, and then use a separation device to completely peel off the cathode copper. Typically, cathode stripping units use a separation knife that screws into the open cathode copper, and a separation frame drives the separation knife to peel off the cathode copper. However, because the separation frame closure is driven by a hydraulic cylinder and positioned by a proximity switch, its operating speed is also very fast, resulting in a large positioning error when the separation frame closes, causing the separation knife to hit the cathode mother plate; at the same time, when the separation knife screws in, it is in close contact with the cathode mother plate, which can easily cause scratches on the mother plate at the contact point. In addition, due to the different deposition density of cathode copper, the bent cathode copper cannot be easily separated from the cathode mother plate. The opening is small, and when the separation knife is screwed in, it exerts a downward pull on the cathode mother plate. The cathode mother plate only relies on the two ends of the conductive beam for support. Long-term downward pull can easily cause the conductive beam of the cathode mother plate to bend and curl up, or even cause the weld between the conductive beam and the plate body to crack. This further leads to increased mechanical damage to the cathode mother plate, increased operation and maintenance costs, and increased workload for personnel. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary positioning device to prevent damage to the cathode motherboard, thereby solving the problem of easy damage to the cathode motherboard.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary positioning device for preventing damage to a cathode motherboard includes a mounting base, a positioning base, a positioning block, a positioning arm, a limiting buffer block, a positioning arm bearing seat, a lower limiting block, a return spring, and a reset mechanism base. The mounting base has several mounting holes. The positioning base and the positioning arm bearing seat are respectively fixedly mounted on the mounting base by bolts, with the positioning arm bearing seat located below the positioning base. The positioning stop is fixedly mounted on the positioning base and located above the positioning arm. The bottom end of the positioning arm is mounted on the positioning arm bearing seat via a pin, and its top end is connected to the limiting buffer block. One end of the reset mechanism base is fixedly mounted on the bottom of the mounting base. The lower limiting block and the return spring are sequentially fixedly mounted on the reset mechanism base, with the lower limiting block located below the positioning arm, and the top end of the return spring connected to the positioning arm.

[0005] As a further explanation of this utility model, the end face of the positioning stop is an inclined surface, which matches the contact surface of the positioning arm. The contact surfaces of the positioning stop and the positioning arm fit tightly together, which can effectively position the upper limit of the positioning arm and reduce impact damage to the positioning arm caused by the positioning stop.

[0006] As a further explanation of this utility model, the mounting hole of the mounting base is a slotted hole. The slotted hole design allows for stepless adjustment of the mounting position of the positioning base and the positioning arm bearing seat, precisely controlling their mounting position and achieving precise positioning and support for the cathode motherboard.

[0007] As a further explanation of this utility model, the limiting buffer block is a polyurethane block. Polyurethane blocks have excellent wear resistance and good cushioning performance. The limiting buffer block, made of polyurethane, is fixed on the positioning arm. In addition to the positioning stop serving as the limit for the separation frame, fine adjustment can also be achieved by adjusting the thickness of the limiting buffer block.

[0008] The usage process (working principle) of this utility model: The auxiliary positioning device of this utility model consists of at least two sets used in conjunction, symmetrically installed on the separation frame. Under normal conditions, the positioning arm is positioned on the lower limit block under the action of the spring. When the separation frame begins to close, the two symmetrically arranged auxiliary positioning devices move closer to each other. After the limit buffer block contacts, the positioning arm rises upward until it contacts the positioning stop bar, thus limiting and fixing its rise and preventing the separation frame from closing further. At this time, the limit buffer block is also in contact with the bottom of the cathode mother plate, serving as a support point for the cathode mother plate. This achieves precise control of the closure degree of the separation frame and reduces the impact of the separation frame driving the separation knife on the cathode mother plate.

[0009] During production, this invention allows for convenient and rapid adjustment of the distance between the separating blade and the cathode mother plate in real time, based on actual production conditions. This ensures that the separating blade does not scratch the mother plate during operation and adds two stress support points to the conductive beam of the cathode plate, reducing the downward pull on the mother plate caused by the separating blade's movement. This prevents the conductive beam of the cathode mother plate from bending or warping, extends the service life of the cathode plate, and reduces maintenance and repair costs and labor intensity.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The positioning base and positioning arm bearing seat of this utility model are fixedly installed in the waist hole of the mounting base by bolts, which can realize stepless adjustment of the installation position of the positioning base and positioning arm bearing seat, thereby realizing precise control of the upper and lower limits of the positioning arm, and further realizing precise control of the closure degree of the separation frame.

[0011] 2. The limiting buffer block set in this utility model can not only reduce the impact of the separation frame closing, but also serve as two new support points for the stainless steel cathode plate. During the cathode plate peeling process, especially when the separation knife is screwed in, it increases the support points of the cathode plate conductive beam, preventing the cathode plate from deforming and warping due to stress at both ends.

[0012] 3. This utility model has a simple structure, a scientific and reasonable design, and low operating costs. It can effectively solve the shortcomings of existing cathode stripping units, improve the service life of cathode plates, and reduce maintenance and repair costs and labor intensity.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments. Specific experimental conditions and methods not specified in the following embodiments are generally conventional methods well known to those skilled in the art.

[0018] Example: Figure 1As shown, an auxiliary positioning device for preventing damage to a cathode motherboard includes a mounting base 1, a positioning base 2, a positioning block 4, a positioning arm 5, a limiting buffer block 6, a positioning arm bearing seat 7, a lower limiting block 9, a reset spring 10, and a reset mechanism base 11. The mounting base 1 has several mounting holes. The positioning base 2 and the positioning arm bearing seat 7 are respectively fixedly mounted on the mounting base 1 by bolts, with the positioning arm bearing seat 7 located below the positioning base 2. The positioning stop 4 is fixedly mounted on the positioning base 2 and located above the positioning arm 5. The bottom end of the positioning arm 5 is mounted on the positioning arm bearing seat 7 via a pin 8, and its top end is connected to the limiting buffer block 6. One end of the reset mechanism base 11 is fixedly mounted on the bottom of the mounting base 1. The lower limiting block 9 and the reset spring 10 are sequentially fixedly mounted on the reset mechanism base 11, with the lower limiting block 9 located below the positioning arm 5, and the top end of the reset spring 10 connected to the positioning arm 5.

[0019] Furthermore, the end face of the positioning stop 4 is an inclined surface, which matches the contact surface of the positioning arm 5.

[0020] Furthermore, the mounting hole of the mounting base 1 is a waist hole.

[0021] Furthermore, the limiting buffer block is a polyurethane block.

[0022] The usage process (working principle) of this embodiment: like Figure 2 and Figure 3 As shown, the auxiliary positioning device in this embodiment consists of at least two sets used in conjunction, symmetrically installed on the separation frame. Under normal conditions, the positioning arm 5 is positioned on the lower limit block 9 under the action of the return spring 10. When the separation frame begins to close, the two symmetrically arranged auxiliary positioning devices move closer to each other. After the limit buffer block 6 contacts, the positioning arm 5 is raised upward until it contacts the positioning stop bar 4, which limits and fixes the position, stopping the rise and thus restricting the separation frame from closing again. At this time, the limit buffer block 6 is also in contact with the bottom of the cathode mother plate 12, serving as a support point for the cathode mother plate 12. This achieves precise control of the closure degree of the separation frame and reduces the impact of the separation frame driving the separation knife 13 on the cathode mother plate 12.
