Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper, in particular to a seed plate sorting device. Background Art

[0002] At present, in the domestic copper electrolysis process, most of the copper liquid that has been refined in the anode furnace is cast into an anode plate as the anode, and the titanium seed plate is used as the cathode for electrolysis in the seed plate tank. The copper ions dissolve from the anode and enter the electrolyte, and precipitate on the cathode titanium plate. When the copper skin on the cathode plate is 0.5 to 0.7 mm thick, it can be removed from the tank. The middle layer of the assembly plate that has been removed from the tank is the cathode titanium plate. The copper skin generated on both sides of the plate surface of the cathode titanium plate is called the seed plate or the starting plate. After the seed plate is processed, it can continue to be used as the cathode in the electrolytic cell for producing finished copper. In the above copper electrolysis process, the seed plates generated on different cathode plates have different thicknesses, and copper nodules may form on the surface of some seed plates, so the seed plates need to be inspected and sorted. In the traditional process, workers roughly judge whether the thickness of the seed board is qualified by feeling the weight of the seed board while manually carrying it, and at the same time check whether there are nodules on the surface of the seed board by naked eye. The efficiency of manual sorting is low and the detection is not accurate enough. Therefore, an automated seed board sorting device is needed to complete the above process accurately and efficiently. Utility Model Content

[0003] The purpose of the utility model is to provide a seed plate sorting device, which can efficiently and accurately complete the automatic detection and sorting process of seed plates.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: seed plates are arranged at intervals along the seed plate conveying line along its own conveying direction, with the inner plate surface of the seed plates facing down and in contact with the conveying roller surface, and the outer plate surface facing up. A seed plate detection station is set in the middle section of the seed plate conveying line, and a seed plate sorting station is set at the downstream end of the seed plate conveying line. The seed plate sorting station includes a waste collection station and a qualified product packing station. The waste collection station and the qualified product packing station are respectively provided with a transfer trolley for transferring the seed plates. The qualified seed plates after inspection by the seed plate detection station are collected at the qualified product packing station for preparation of cathode plates for production of electrolytic copper, and the defective seed plates A are collected at the waste collection station 22 and then transported to a recycling station or to the lifting ears for preparation of cathode plates for production of electrolytic copper.

[0005] The utility model mainly sets a seed board detection station in the middle section of the seed board conveying line to detect whether the thickness of the seed board meets the standard and whether there are nodules on the outer board surface, so as to mark the seed board as a qualified product or a defective product. The seed boards are classified and placed according to the marks of the previous process through the seed board sorting station, so that the detection standard of each seed board A is unified, the detection accuracy is greatly improved, and human resources are saved.

[0010] See also Figs. 1-4 The seed plate sorting device shown in the figure has seed plates A arranged at intervals along the seed plate conveying line 1 in its own conveying direction. The seed plates A are arranged with the inner plate surface facing downward and in contact with the conveying roller surface, and the outer plate surface facing upward. A seed plate detection station 10 is set in the middle section of the seed plate conveying line 1, and a seed plate sorting station 20 is set at the downstream end of the seed plate conveying line 1. The seed plate sorting station 20 includes a waste collection station 22 and a qualified product packing station 21. The waste collection station 22 and the qualified product packing station 21 are respectively provided with a transfer trolley 30 for transferring the seed plates A. The qualified seed plates A after inspection by the seed plate detection station 10 are collected and stored at the qualified product packing station 21 for preparation of cathode plates for producing electrolytic copper. The defective seed plates A are collected and stored at the waste collection station 22 and then transported to a recycling station or to the lifting ears for preparing cathode plates for producing electrolytic copper.

[0011] In the above scheme, the preceding process of the seed board inspection station 10 includes a trimming station for cutting the edges of the seed board A, so that the size specifications of each seed board A are uniform. The seed board A is arranged with the inner side facing down and in contact with the conveyor roller surface and the outer side facing up, which facilitates the seed board inspection station 10 to uniformly inspect whether there are nodules on the outer side of the seed board A. Seed boards A with nodules on the surface or boards that do not meet the thickness standards will be marked as defective products at the seed board inspection station 10. Otherwise, they will be marked as qualified products and sorted and placed in the seed board sorting station 20 by sorting robots. The inspection standards of each seed board A are unified, and the inspection accuracy is greatly improved, saving labor costs.

[0012] The sorting robot at the seed board sorting station 20 includes a gripping end 201 and a sorting robot arm 202. The gripping end 201 can rotate around its own center. The gripping end 201 is connected to a vacuum air source and grasps the seed board A through a vacuum suction cup and is driven to move by the sorting robot arm 202. The sorting robot transfers the seed board A to the waste collection station 22 or the qualified product boxing station 21 according to the inspection results of the seed board inspection station 10. In the above scheme, a vacuum adsorption structure is provided at the bottom of the gripping end 201. According to the inspection results of the seed board inspection station 10, the sorting robot places the seed board A marked as qualified products at the qualified product boxing station 21, and places the seed board A marked as defective products at the waste collection station 22. In the cathode plate peeling station in the previous process, the seed plates A peeled on both sides of the cathode plate surface fall onto the seed plate conveying line 1 in a posture that is roughly symmetrical relative to the cathode plate. Therefore, the grabbing end 201 of the sorting robot can rotate around its own center to facilitate adjustment of the placement posture of the seed plate A when grabbing the seed plate A. In other words, if the sorting robot grabs the previous seed plate A and places it directly without rotating it, the grabbing end 201 of the robot needs to rotate the plate 180 degrees around its own center before placing it when grabbing the next seed plate A, thereby ensuring that the stacking postures of the two seed plates A are consistent, which is convenient for subsequent repair or packaging processes.

[0013] Regarding the specific inspection method for seed plate A, the seed plate inspection station 10 is equipped with a weighing unit to measure the weight of seed plate A and an optical detection unit to detect the presence of copper nodules on the surface of the seed plate. The optical detection unit is located above seed plate A and its detection direction is toward the outer surface of seed plate A. The weighing unit measures the weight of seed plate A to infer whether the thickness of seed plate A meets the standard. The optical detection unit captures an image of the outer surface of seed plate A and determines whether there are nodules on the outer surface of seed plate A. If both the thickness and surface flatness of seed plate A meet the standards, it is marked as qualified; otherwise, it is marked as defective.

[0014] To stabilize the tabletop of the transfer cart 30, hemispherical positioning blocks 331 are installed between the tabletop 33 on which the seed plates A are placed and the base of the cart. The positioning blocks 331 are located diagonally on the tabletop 33. Since the sorting robot's movement and placement of the seed plates A are fixed, any deviation in the position of the tabletop 33 relative to the base of the cart would cause the sorting robot's gripping end 201 to collide with the surrounding barriers 32. The positioning blocks 331 ensure that the tabletop 33 on which the seed plates A are placed is fixed relative to the base of the cart.

[0015] To regularize the stacking of seed boards A, upright rod-shaped fences 32 are provided around the table 33 on which the transfer cart 30 places the seed boards A. The square area enclosed by the fences 32 is consistent with the shape of the surface of the seed boards A and its enclosed area is larger than the surface area of ​​the seed boards A. The bottom of the picking end 201 of the sorting robot is square in shape, consistent with the surface of the seed boards A, and its horizontal projection is smaller than the table surface enclosed by the fences 32. The shape consistency here does not strictly require that it must be completely identical in the geometric sense, that is, basically consistent is sufficient.

[0016] In the above scheme, the bottom of the gripping end 201 is square and flat. On the one hand, it can facilitate the vacuum adsorption structure inside it to adsorb on the four corners of the seed board A near the edge. On the other hand, it can help the transfer cart 30 to regularize the stacking posture of the seed board A. Since the thickness of the seed board A is very thin, even if the seed board A is placed horizontally, its board surface will still naturally warp, especially the warping amplitude at the corners is larger. Moreover, the flatness and thickness of each piece of seed board A are slightly different. The above factors may cause large gaps between adjacent board surfaces of the seed boards A when stacking, which is not conducive to subsequent packaging and other processes. Therefore, every time the sorting robot stacks 3 to 8 seed boards A in the transfer cart 30, the gripping end 201 moves a distance at a constant speed from the top of the transfer cart 30 toward the board surface of the seed board A, contacts and presses the board surface of the top layer of seed board A, so as to eliminate the gaps between the adjacent board surfaces of the seed board A, reduce the warping amplitude of the stacked seed boards A, and improve the packaging efficiency of the seed boards A.

[0017] In order to facilitate the removal of the stored seed plates A from the table 33, the enclosure 32 is set at the corner of the table 33. A gap is left between two adjacent enclosures 32 around the table 33 to facilitate forklifts or other tools to remove the seed plates A from the gap.

[0018] In order to facilitate the transportation of seed boards A stored at the qualified product packing station 21 or the waste product collection station 22, a guide rail is provided between the table on which the seed boards A are placed and the base of the transfer trolley 30, and the table slides on the guide rail. The guide rail extends in a direction perpendicular to the conveying direction of the transfer trolley 30. The transfer trolley 30 is equipped with a motor, which drives the table on which the seed boards A are placed to slide on the guide rail through a screw-nut mechanism.
