Description

Technical Field

[0001] The present invention relates to a process system for electrolytic copper, in particular to a device for identifying and removing unqualified secondary electrolytic copper. Background Art

[0002] The copper electrolysis process involves placing anode and cathode plates in an electrolytic cell, where copper ions are ionized and deposited on the cathode plates to produce high-purity electrolytic copper. Due to various reasons, conventional copper electrolysis production produces 1-3% of inferior copper that does not meet the requirements for sale as Grade A copper. Based on the applicant's current production capacity, this yields approximately 150 pieces of inferior copper per day. These inferior (or defective) products are washed, stacked, and packaged along with Grade A copper in the process line. They are then transported off-site by forklift for manual inspection. Defective copper is then sorted by forklift, reclassified, and stacked. Grade A and B copper are also manually packaged and shipped to the storage yard. Identifying and removing defective cathode copper at the cleaning station requires significant staffing, and removing the defective copper from the conveyor chain is physically demanding.

[0003] The title is "Unqualified Cathode Copper Picking Device" (Document No. CN 203569219 U). As can be seen from the technical solution disclosed in the document, it also focuses on the identification and removal of defective products. Putting aside the advantages and disadvantages of the technical solution disclosed in the above document when picking up the plates, the problem is that its technical solution does not involve the regularity of the plate sorting. In order to ensure that the picking mechanism can accurately hook the corresponding cathode copper plate, there are actually strict requirements for the position of the plate to be picked up by the picking device. Otherwise, the plate will deviate from the accurate picking position. If the deviation is too large, the device will not be able to pick up the corresponding plate, or when it is barely picked up, the hook may become unstable due to the deviation of the plate and fall. Summary of the Invention

[0004] The purpose of the present invention is to provide a cathode copper adjustment device, which adjusts the cathode plates to be evenly spaced along the conveying direction on the conveying chain and arranged in a manner such that the symmetry lines of the cathode plates in the width direction are coplanar and move toward the position to be picked up.

[0005] To achieve the above-mentioned purpose, the present invention has adopted the following technical solutions: a cathode copper adjustment device, comprising guide walls, which are respectively arranged below the conveyor chains at both ends of the conductive rod for carrying the electrode plate. The height of the guide walls is located at the upper position of the left and right sides of the electrode plate. The spacing between the left and right guide walls is consistent with the plate width between the left and right sides of the electrode plate. Blocking slopes are respectively arranged on the inner sides of the conveying chains on the left and right sides. The slope shape of the blocking slope is a lifting section that slowly rises from a low position to a high position from upstream to downstream, and a straight section that maintains a high position and extends. The height of the straight section on the blocking slope is lower than the height of the rear baffle of the chain plate, and the height H of the straight section above the upper side of the chain plate of the conveying chain is less than 1 / 2 of the conveying direction dimension of the conductive rod cross section.

[0006] The above scheme has two functions and effects. The first is that the guide walls under the conveyor chains on the left and right sides respectively apply squeeze and push from the two sides of the cathode plate to adjust the displacement of the cathode plate to the central symmetry plane in the width direction of the conveyor chain, that is, adjust the position of the left and right symmetric center lines of the cathode plate to the set position; the second is that the blocking slopes set adjacent to the inner side of the conveyor chains on both sides apply reverse obstruction to the forward direction of the conductive rod of the cathode plate supported on the conveyor chain, so that the conductive rod is delayed in displacement and abuts against the front vertical edge of the rear baffle of the chain plate on the conveyor chain, so that the cathode plates at the upstream and downstream positions are separated by a distance of one chain link. The adjustment device provided by the present invention is to adjust the electrode plates to the above-mentioned neatly sorted state and convey them to the position to be picked up, thereby providing basic guarantee for the picking device to safely, reliably and accurately pick up secondary or defective cathode copper plates.

[0011] For ease of explanation, let's briefly describe the basic structure of plate A. The upper portion of plate A consists of a connecting plate A3, made of copper strips or other conductive metal, looped around the left and right sections of conductive rod A1. The lower end of copper strips A3 is typically riveted to the plate's upper edge A2. Plate A in the figure should be understood as a base plate with electrolytic copper attached. A chain plate rear plate 2B is attached to the rear end of the upper edge 2A of the chain link of conveyor chain 1. The above information is all prior art. The arrows in the figure indicate the conveying direction of conveyor chain 1. Left and right directions are defined when the viewing direction aligns with the conveying direction.

[0012] Since the ends of the conductive rods A1 are uneven in the initial state when the plate A hoisted by the crane is placed on the conveyor chain 1, and the distances between the conductive rods A1 and the chain plate rear baffle 2B of the conveyor chain 1 are also different in size, the present invention is to adjust and correct the above-mentioned disordered sorting state of the plate A.

[0013] Combine Figures 1 to 6 The cathode copper adjustment device includes a guide wall 10, which is respectively arranged under the conveyor chain 1 at both ends of the conductive rod A1 for carrying the electrode A. The height of the guide wall 10 is located at the upper position of the left and right sides of the electrode plate A. The spacing between the left and right guide walls 10 is consistent with the plate width between the left and right sides of the electrode plate A. Blocking slopes 20 are respectively provided on the inner sides of the conveyor chains 1 on the left and right sides. The slope shape of the blocking slope 20 is a lifting section 21 that slowly rises from a low position to a high position from upstream to downstream, and a straight section 22 that maintains a high position and extends. The height of the straight section 22 on the blocking slope 20 is lower than the height of the chain plate rear baffle 2B, and the height H of the straight section 22 above the chain plate upper side 2A of the conveyor chain 1 is less than 1 / 2 of the conveying direction dimension of the conductive rod A1 cross section.

[0014] The height of the guide wall 10 is set at the upper position of the side of the electrode plate A, which can prevent the electrode plate A from swinging too much when it is blocked by the contact with the guide wall 10. Since the distance between the upstream and downstream electrode plates A is originally small, if the electrode plate A swings too much, there will be a risk of the upstream and downstream electrode plates A colliding with each other; the distance between the guide walls 10 on the opposite sides is consistent with the size between the two side edges of the electrode plate A, which can ensure that after the electrode plate A is pushed and constrained by the guide walls 10 on both sides, the left and right symmetrical center line of the electrode plate A is centered at the set position. The fixed center position can be defined as the center position of the left and right conveyor chains 1; the height of the guide wall 10 is set at the upper position of the side of the electrode plate A. The core is to determine the position of the center of gravity of the electrode plate A in the left and right directions rather than the center position of the conductive rod A1, because there is an error between the center of the conductive rod A1 and the center of mass of the electrode plate A, that is, the two are not located on the same plumb line in the width direction of the electrode plate A. Since the position of the picking device in the downstream section is fixed, it is necessary to ensure that the resultant force of the lifting force when the picking device picks up the electrode plate A coincides with the mass center of the electrode plate A as much as possible.

[0015] Under the hysteresis and guidance of the lifting section 21, the conductive rod A1 is lifted to the straight section 22. At this time, the conductive rod A1 is separated from the upper side 2A of the chain plate. Figure 4a 、 4b As shown, and under the hysteresis obstruction of the lifting section 21 and the straight section 22, the chain plate rear baffle 2B of the conveyor chain 1 that continues to move downstream will inevitably abut against the rear rod surface of the conductive rod A1 and push the conductive rod A1 to slide downstream on the straight section 22. When the conductive rod A1 reaches the downstream end of the straight section 22, due to the continuous pushing action of the chain plate rear baffle 2B, the conductive rod A1 gradually separates from the straight section 22. Since the straight section 22 is higher than the chain plate upper side 2A of the conveyor chain 1 by a limited height H, before the conductive rod A1 is completely separated from the straight section 22, the front side of its lower rod surface begins to drop and fall on the chain plate upper side 2A. Under the continuous pushing of the chain plate rear baffle 2B, the conductive rod A1 and the chain plate rear baffle 2B maintain a close or close contact state and continue to move downstream until the conductive rod A1 is completely separated from the straight section 22. The chain plate rear baffle 2B is still squeezing and pushing the conductive rod A1. Figure 4c shown.

[0016] Under the restraining action of the guide walls 10 and the blocking slopes 20 arranged on both sides, the electrode A will maintain a sorting state of being centered left and right and equidistant from front to back until it reaches the position to be picked up. It should be emphasized here that the main function of the lifting section 21 is to achieve the contact state between the conductive rod A1 and the chain plate rear baffle 2B, while the function of the straight section 22 is to maintain and continue the contact state between the conductive rod A1 and the chain plate rear baffle 2B. The height difference between the straight section 22 and the upper side 2A of the chain plate can prevent the conductive rod A1 from suddenly sliding downstream or being thrown horizontally and separating from the chain plate rear baffle 2B and the separation distance from each other, while avoiding the misalignment problem of the conductive rods A1 on the left and right sides in the conveying direction. The lifting section 21 and the straight section 22 provided by the present invention can ensure that the conductive rod A1 and the chain plate rear baffle 2B maintain a close relationship when the conductive rod A1 falls back to the upper side 2A of the chain plate. Even if there is a slight error of 1 to 2 mm, it will not affect the accurate picking of the subsequent picking device.

[0017] As a preferred embodiment, the guide wall 10 is located upstream of the blocking slope 20. Using the guide wall 10 to adjust the electrode plate A's centering will additionally cause the conductive rod A1's position on the conveyor chain 1 to change in the upstream and downstream directions. Therefore, the guide wall 10 is first provided to adjust the electrode plate A's centering, and the blocking slope 20 is then provided downstream. The blocking slope 20 only adjusts the conductive rod A1's position on the conveyor chain 1 in the upstream and downstream directions, without causing a change in the centering position of the electrode plate A. Conversely, if the guide wall 10 is provided downstream of the blocking slope 20, the previously adjusted conductive rod A1's position on the conveyor chain 1 may shift and change during the centering adjustment process provided by the guide wall 10. This may result in uncertainty in the relative position between the conductive rod A1 and the chain plate rear baffle 2B, rendering the previously implemented adjustment of the conductive rod A1's position on the conveyor chain 1 in the upstream and downstream directions ineffective.

[0018] Preferably, the guide walls 10 are arranged in an upstream and downstream staggered manner, which can further reduce the amplitude of the front-back swing of the electrode plate A when it is centered.

[0019] Preferably, the blocking slopes 20 on both sides are staggered in upstream and downstream, which can reduce the swing of the pole plate A due to inertia and reduce the displacement of the conductive rod A1 in the length direction, that is, basically maintain the central position completed by the guide wall 10.

[0020] More preferably, the downstream guide wall 10 is located upstream of the upstream blocking slope 20. This requires that the position of the electrode plate A in the conveying direction be adjusted after the electrode plate A is centered.

[0021] In order to ensure that the conductive rod A1 is securely placed on the conveyor chain 1, and at the same time the conductive rod A1 maintains contact with the chain plate rear baffle 2B, the height H of the straight section 22 above the upper side 2A of the chain plate of the conveyor chain 1 is less than 5 mm. The preferred embodiment is that the height H of the straight section 22 above the upper side 2A of the chain plate of the conveyor chain 1 is 2 to 3 mm. In the actual production process, the distance between the pole A1 and the chain plate rear baffle 2B is usually less than 2 mm. For the downstream pickup device, the position accuracy fully meets the requirements.

[0022] The lifting section 21 and the straight section 22 are made of hard rubber or nylon 6. Figure 7 、 8 As shown, in order to ensure that the lifting section 21 and the straight section 22 maintain their shape and posture, a low section 23 is added downstream of the straight section 22. A steep wall section 24 is used to transition between the straight section 22 and the low section 23. Step holes are respectively opened at the top of the low section 23, the straight section 22 and the low section 23, and they are fixed to the lower base plate 20a with screws. The base plate 20a is connected to the frame of the conveyor chain 1.

[0023] As a preferred embodiment, guide wall 10 comprises a guide surface 11 with a plate surface located in the plumb line, a midstream straight guide surface 112 parallel to the conveying direction, and an upstream guide surface 111 transitioning from the outside to the inside along the conveying direction to the midstream straight guide surface 112. A downstream section 113 is arranged from the inside to the outside along the conveying direction. The design of guide surface 11 as upstream guide surface 111 and midstream straight guide surface 112 ensures a continuous mating path between guide surface 11 and electrode plate A. This prevents large swings in electrode plate A, significantly reducing the inevitable swing that occurs with brief or momentary contact.

[0024] Next, the right midstream straight guide surface 112 intervenes to push and center the plate. Because the midstream straight guide surfaces 112 on both sides overlap, the left and right midstream straight guide surfaces 112 experience a period of shared centering and constraint. This reliably and stably defines the widthwise position of the plate A, effectively limiting wobbling during the centering adjustment process. Therefore, the center of the spacing between the left and right midstream straight guide surfaces 112 can be considered the set widthwise adjustment center of the plate A. Avoiding wobbling of the plate A during the adjustment process is also important because wobbling can cause displacement of the plate A in the left-right width direction, making accurate left-right centering impossible.
