Description

Technical Field

[0001] The utility model patent relates to a cathode copper production system, and specifically to a system for identifying and removing defective copper plates in cathode copper. Background Art

[0002] Cathode copper, also known as electrolytic copper, is anode plates made by refining copper from matte smelted in a smelting furnace in an anode furnace. Anode plates and cathode plates are arranged in an electrolytic cell with a mixture of sulfuric acid and copper sulfate as the electrolyte. After power is turned on, the copper ions on the anode plates move to the cathode plates with the help of the electrolyte, and after reaching the cathode, they obtain electrons and precipitate pure copper on the cathode plates. The copper plates produced in this way are of extremely high quality and can be used to make various electrical products.

[0003] In the production process of cathode copper, the cathode plate taken out of the electrolytic cell is attached with a cathode copper plate. Since the cathode copper plate is attached with electrolyte and attached to the cathode plate, the cathode copper needs to be washed and stripped before the cathode copper plate can be obtained. Among them, 1%-3% of unqualified cathode copper, also known as defective copper, will be produced during the electrolytic production process. This type of defective copper needs to be manually identified and removed. The existing means of identifying and removing defective copper is to first use a crane to lift the cathode plate that meets the electrolysis time in the electrolytic cell and temporarily place it on the receiving rack, manually identify each cathode plate and mark the defective cathode plate edge or conductive rod with chalk, and then the transfer trolley will transfer the cathode plates on the receiving rack to the washing conveyor chain in turn. The washing conveyor chain carries the cathode plates through the washing room for washing, and then the transfer robot picks up the cathode plates to the stripping unit for stripping. The rejection of defective cathode copper plates can be carried out in the upstream or downstream section of the stripping unit. Due to the water flow during the washing process, the defect marks made when they are temporarily placed on the receiving rack will be washed away by the water flow or the marks will be blurred and difficult to identify, making the rejection difficult. That is, the defective cathode plates need to be reconfirmed again, which not only consumes a lot of manpower, but also seriously affects the normal operation of the stripping unit and subsequent processes, and even causes the defective cathode copper plates to be mistakenly rejected. Summary of the invention

[0004] The utility model provides a cathode copper processing system, which does not need repeated marking after the cathode copper is washed and can accurately remove defective copper plates from the unit production line.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted is: a cathode copper processing system, including a cathode copper receiving rack, the downstream end of the receiving rack is connected to the upstream end of the washing transmission chain running through the washing room, the washing transmission chain conveys the washed cathode copper to the stripping unit, the cathode copper plate stripped by the stripping unit is conveyed to the packaging unit by the conveyor chain, the lower part of each concave support of the conductive rod on the cathode plate on the receiving rack for supporting the cathode copper is marked with a seat number, the input unit connected to the control unit for communication inputs the seat number corresponding to the cathode copper plate with defects on the board surface; the rejection unit arranged between the stripping unit and the packaging unit receives the control command of the control unit and picks up the cathode copper plate with defects on the board surface to the temporary storage area of ​​the defective cathode copper plate.

[0006] Compared with the prior art, the technical effect of the utility model is as follows: the seat number corresponding to the cathode copper plate with defects on the board surface is input into the control unit by using the input unit, and the rejection unit can receive the control instruction of the control unit and pick up the cathode copper plate with defects on the board surface to the temporary storage area of ​​the defective cathode copper plate. The whole system automatically controls the rejection unit to pick up the cathode copper plate with the corresponding seat number according to the seat number input into the control unit. Even if the mark is washed and difficult to identify, the defective cathode copper plate can be accurately rejected, which effectively improves the processing efficiency of cathode copper.

[0014] The following is combined with Figure 1-7 And related content, the utility model is further described in detail:

[0015] A cathode copper processing system includes a receiving frame 10 for cathode copper A. The downstream end of the receiving frame 10 is connected to the upstream end of a washing transmission chain 21 that runs through a washing room 20. The washing transmission chain 21 conveys the washed cathode copper A to a stripping unit 30. The cathode copper plate A1 stripped by the stripping unit 30 is conveyed to a packaging unit 40 by a conveying chain 80. The lower part of each concave support 11 of a conductive rod A21 on a cathode plate A2 of the cathode copper A on the receiving frame 10 is marked with a seat number 13. An input unit 50 that is communicatively connected to a control unit 60 inputs the seat number 13 corresponding to the cathode copper plate A1 with defects on the plate surface. A rejecting unit 70 arranged between the stripping unit 30 and the packaging unit 40 receives a control instruction from the control unit 60 and picks up the cathode copper plate A1 with defects on the plate surface to a temporary storage area for the defective cathode copper plate A1.

[0016] In the above scheme, during the processing of cathode copper A, the crane lifts the cathode copper A (with cathode copper plate A1 attached thereto) in the electrolytic cell that meets the electrolysis time and temporarily places it in the groove of the concave support 11 on the receiving frame 10 and corresponds to the corresponding seat number 13, and then the transfer trolley transfers the cathode copper A on the receiving frame 10 to the washing conveyor chain 21 in sequence. The washing conveyor chain 21 carries the cathode copper A through the washing room 20 for washing, and then the transfer robot picks up the cathode copper A to the stripping unit 70 for stripping operation. While cathode copper A is temporarily placed on the receiving rack 10, the seat number 13 corresponding to the cathode copper A with defects is manually identified, and the seat number corresponding to the cathode copper plate with defects on the board surface is input into the control unit 60 using the input unit 50. After the cathode copper A is stripped, the cathode copper plate A1 is conveyed to the packaging unit 40 by the conveyor chain 80, and the rejection unit 70 can receive the control instruction of the control unit 60, and can automatically control the rejection unit 70 to pick up the cathode copper plate A1 corresponding to the seat number 13 according to the seat number 13 input into the control unit 60, and pick up the cathode copper plate A1 with defects on the board surface to the temporary storage area of ​​the defective cathode copper plate A1, so that the cathode copper plate A1 with defects can be accurately rejected, thereby avoiding the situation in which the marks made in the traditional way are washed away in the washing room 20 and affecting the normal rejection operation. There is no need to manually confirm multiple times whether the cathode copper plate A1 after stripping needs to be rejected, thereby reducing manpower consumption.

[0017] It should be noted that in the traditional rejection method, the cathode copper A is immediately transferred to the stripping unit 30 for stripping after washing. During this period, the cathode copper A is naturally transported to the downstream process, and the residence time is short, and the manual marking operation is difficult to proceed smoothly. Therefore, it is not suitable to mark the cathode copper A during this period.

[0018] As a preferred solution, the value of the seat number 13 corresponding to each concave support 11 gradually increases from the downstream to the upstream of the receiving frame 10 and is arranged in an arithmetic progression, the first term and the tolerance of the arithmetic progression are both 1, and then an arithmetic progression mark with gradually increasing values ​​of 1, 2, 3, ... is formed on the receiving frame 10, and the mark is located at a position that can be directly observed by humans (such as the outer side of the receiving frame 10) and cannot be easily erased. When the operator needs to enter the defective cathode copper A into the control unit 60, by observing the mark previously made with chalk on the edge of the cathode plate A2 of the defective cathode copper A or the conductive rod A21, the seat number 13 corresponding to the defective cathode copper A can be directly determined, and then the number is transmitted to the control unit 60 through the input unit 50 to ensure that the seat number 13 of the defective cathode copper A is accurately entered.

[0019] Furthermore, a counter 90 for monitoring the total number of cathode copper plates A1 delivered to the downstream end of the conveyor chain 80 is provided at the downstream end of the conveyor chain 80. The value recorded by the counter 90 is transmitted to the control unit 60. When the value recorded by the counter 90 received by the control unit 60 is consistent with the seat number 13 corresponding to the cathode copper plate A1 with defects on the plate surface, the rejection unit 70 receives the control command of the control unit 60 and picks up the defective cathode copper plate A1 currently located at the downstream end of the conveyor chain 80 to the temporary storage area of ​​the defective cathode copper plate A1.

[0020] In this solution, cathode copper A is transferred to the conveyor chain 80 after stripping, and is transported to the packaging unit 40 by the conveyor chain 80. The setting of the counter 90 can record the total number of cathode copper plates A1 transported to the downstream end of the conveyor chain 80. It can be seen that when the counter 90 records a value of 1, it corresponds to the cathode copper A at the position marked "1" on the previous receiving frame 10. By analogy, the value recorded by the counter 90 corresponds to the cathode copper at the corresponding seat number 13 on the receiving frame 10. After the corresponding seat number 13 is entered into the control unit 60, when the value of the counter 90 reaches the same value, the rejection unit 70 receives the control instruction of the control unit 60, and then picks up the cathode copper plate A1 to the temporary storage area of ​​the defective cathode copper plate A1, realizing the automatic rejection function. Even if the mark previously made with chalk is missing, there is no need to manually identify whether it is a defective cathode copper plate A1 again, which greatly improves the processing efficiency of cathode copper A.

[0021] It should be noted that each time a batch of cathode copper A is replaced on the receiving rack 10, the value of the counter 90 is initialized once to ensure that the value recorded by the counter 90 corresponds to the seat number 13 on the receiving rack 10, thereby avoiding the inconvenience of the counter 90 accumulating counts of cathode copper plates A1 of different batches and causing the need to match subsequent values ​​with the seat number 13, thereby solving the problem of large accumulated count values.

[0022] Combination Figure 2 , 3 As shown in Figures 4 and 5, the receiving frame 10 includes two guide rails 12 located at the same height in the horizontal direction and arranged in parallel with each other. The transfer trolley is located on the guide rails 12 and forms a guide limit match with the guide rails 12. The concave supports 11 are arranged on the opposite sides of the two guide rails 12 and the two concave supports 11 adjacent to the same side are connected to each other to form a toothed plate. The transfer trolley moves along the guide rails 12 to transport the cathode copper A temporarily placed on the receiving frame 10 to the washing transmission chain 21 of the washing room 20. Specifically, the two suspended ends of the conductive rod A21 on the cathode plate A2 can be placed in the two concave supports 11 opposite to each other on the two guide rails 12. The transfer trolley can lift the conductive rod A21 on the cathode plate A2 located in the concave support 11 to disengage it from the groove of the concave support 11. By supporting the conductive rod A21, the cathode copper A can be moved as a whole to the washing transmission chain 21 with the transfer trolley to realize the transfer operation of the cathode copper A.

[0023] like Figure 6 As shown, the notch of the groove on the concave support 11 is arranged upward, the bottom surface of the groove is located in the horizontal plane, and the notch is in a flared shape. In the prior art, the cross section of the conductive rod A21 of the cathode plate A2 is generally rectangular, so the bottom surface of the groove on the concave support 11 is located in the horizontal plane to ensure that the conductive rod A21 of the cathode plate A2 is placed horizontally on the bottom surface of the groove as a whole and will not rotate, avoiding the situation where the conductive rod A21 is unstable and affects the overall stability of the cathode copper A during temporary placement on the concave support 11 or during transportation, ensuring that the posture of the cathode copper A during temporary placement or transportation remains in a relatively stable state, so that the cathode copper A can be stably transferred to the next process.
