Description

Technical Field

[0001] The utility model relates to the technical field of copper electrolysis, in particular to a cathode plate transporting 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 skins generated on both sides of the plate surface of the cathode titanium plate are called seed plates or starting plates. After the seed plates are processed, they can continue to be used as cathodes in the electrolytic cell for producing finished copper. After the seed plate is generated on the cathode plate, it needs to be peeled off from the cathode plate. The electrolysis time for crude copper is about 22.5 hours. In order to complete the production cycle within one day, it is generally necessary to peel off the seed plate and return the cathode plate to the tank within 1.5 hours. In the traditional process, the crane will lift the cathode plates with seed plates attached to them to the work site. Workers stand next to the crane's lifting frame and directly peel the seed plates from the cathode plates. During the manual handling process, the quality of the seed plates is identified and they are classified and packed. This process is time-sensitive, labor-intensive and takes up the crane's operating time. If the above process is to be automated and iterated, the automated transfer of cathode plates between the seed plate peeling and conveying processes is an indispensable link. Utility Model Content

[0003] The utility model aims to provide a cathode plate transfer device, which can efficiently transfer cathode plates on a conveying line to adjust their arrangement posture.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: cathode plates are suspended on the first row of conveying lines, and the plate surfaces of the cathode plates located in the plumb plane are coplanar and the vertical plate edges on the adjacent sides are arranged in rows. A grabbing and transferring mechanism and a bracket are provided at the downstream end of the first row of conveying lines. The grabbing and transferring mechanism connects the column conveying lines. The cathode plates on the column conveying lines are parallel to the plate surfaces located in the plumb plane and are arranged in rows. The grabbing and transferring mechanism moves on the bracket, and its displacement direction is consistent with the conveying direction of the column conveying lines. A grabbing unit that moves in the vertical direction is provided at the bottom of the grabbing and transferring mechanism. The grabbing unit moves downward from the top of the first row of conveying lines and hooks the conductive rod of the cathode plate. The upward displacement causes the conductive rod to leave the hanger of the first row of conveying lines and lifts the cathode plate to the conveying chain of the column conveying lines through horizontal and vertical displacements.

[0005] The utility model mainly sets a grabbing and transferring mechanism and a bracket at the downstream end of the first row of conveying lines. The grabbing unit of the grabbing and transferring mechanism lifts the cathode plate B to the conveying chain of the column conveying line through horizontal and vertical displacement, realizing the automatic transfer of the cathode plate between the two conveying lines. Compared with traditional manual handling, it reduces the time occupied by driving, improves the efficiency of cathode plate transfer and saves human resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] See also Figures 1 to 4 The cathode plate transfer device shown in the figure has cathode plates B suspended on the first row of conveying lines 1, and the plate surfaces of the cathode plates B located in the plumb plane are coplanar and the vertical plate edges on the adjacent sides are arranged in rows. The downstream end of the first row of conveying lines 1 is provided with a grabbing and transferring mechanism 20 and a bracket 21. The grabbing and transferring mechanism 20 is connected to the column conveying lines 3. The cathode plates B on the column conveying lines 3 are parallel to the plate surfaces located in the plumb plane and are arranged in rows. The grabbing and transferring mechanism 20 moves on the bracket 21, and its displacement direction is consistent with the conveying direction of the column conveying lines 3. The bottom of the grabbing and transferring mechanism 20 is provided with a grabbing unit 22 that moves in the vertical direction. The grabbing unit 22 moves downward from the top of the first row of conveying lines 1 and hooks the conductive rod B' of the cathode plate B. The upward displacement causes the conductive rod B' to leave the hanger 4 of the first row of conveying lines 1 and lifts the cathode plate B to the conveying chain 31 of the column conveying lines 3 through horizontal and vertical displacement.

[0011] In the above scheme, the bracket 21 is fixed on the ground, and a guide rail is set on the top of the bracket for the movement of the grabbing and transferring mechanism 20. In the automated processing process of the cathode plate, the plate surfaces of the cathode plates B on the first row of conveyor lines 1 are respectively coplanar and the vertical plate edges of the adjacent sides are arranged in rows, which can facilitate the arrangement of the stripping station and the cathode plate detection station in the previous process, and provide sufficient space for stripping, detection and other equipment. However, the cathode plate occupies a large space in the above posture, which is not convenient for centralized lifting by crane. Therefore, a grabbing and transferring mechanism 20 is set to lift the cathode plate from the top of the first row of conveyor lines 1 to the column conveyor line 3, completing the adjustment of the cathode plate suspension arrangement method, facilitating subsequent centralized lifting by crane, and compared with traditional manual handling, the transportation efficiency of the cathode plate is obviously higher.

[0012] In order to improve the efficiency of stripping, detection and conveying of cathode plates, two parallel rows of conveying lines can be set, that is, the second row of conveying lines 2 are arranged parallel to and spaced apart from the first row of conveying lines 1, and the plate surfaces of the same row of cathode plates B located in the plumb plane are coplanar and the vertical plate edges on the adjacent sides are arranged in rows, and the downstream end of the second row of conveying lines 2 is connected to the grabbing and transferring mechanism 20, and the grabbing unit 22 simultaneously grabs the cathode plates B at the downstream ends of the first row of conveying lines 1 and the second row of conveying lines 2 and lifts them together to the conveying chain 31 of the column conveying line 3, and the cathode plates B at the downstream ends of the second row of conveying lines 2 and the first row of conveying lines 1 are arranged in upstream and downstream positions in the conveying direction of the column conveying line 3. This arrangement enables the grabbing unit 22 to transfer the cathode plates B on the two rows of conveying lines to the column conveying line 3 at the same time, and the cathode plates B are also arranged in upstream and downstream on the conveying chain 31 and continue to be conveyed to the downstream of the column conveying line 3.

[0013] A more specific solution is that a mobile trolley 10 and a fixed frame 11 are also provided at the downstream end of the second row of conveying lines 2. The fixed frame 11 is located on the moving path of the grabbing and transferring mechanism 20. The mobile trolley 10 moves horizontally along the fixed frame 11 and its moving direction is consistent with the conveying direction of the column conveying line 3. The top of the fixed frame 11 is provided with a support point 111 for suspending the cathode plate B. The top of the mobile trolley 10 is provided with a lifting unit 12 that moves in the vertical direction. The lifting unit 12 moves upward from the bottom of the hanger 4 of the first row of conveying lines 1 to lift the conductive rod B', and moves the cathode plate B in the horizontal and vertical directions to the support point 111 of the fixed frame 11. The grabbing unit 22 simultaneously grabs the cathode plate B at the downstream end of the first row of conveying lines 1 and the cathode plate B on the fixed frame 11 adjacent to the cathode plate B and lifts them together to the conveying chain 31 of the column conveying line 3.

[0014] In the above scheme, the fixed frame 11 is fixed to the ground and the bottom of the fixed frame 11 is provided with a guide rail for the sliding of the mobile trolley 10. The mobile trolley 10 adopts a frame structure to facilitate the transportation of the cathode plates B. The number of lifting units 12 on the mobile trolley 10 is preferably 3, that is, the mobile trolley lifts 3 cathode plates B at the same time in each movement cycle, transfers the cathode plates B on the second row of conveying lines 2 to the support point 111, and moves the two cathode plates B originally on the support point 111 to the next support point 111 in the direction of the column conveying line 3. The cathode plate originally on the support point 111 adjacent to the first row of conveying lines 1 is grabbed by the grabbing unit 22 and transferred to the column conveying line 3. In order to meet the above-mentioned transportation rhythm, the distance L1 between the two adjacent support points 111 on the fixed frame 11, the distance L1 between the cathode plate B at the downstream end of the first row of conveying lines 1 and its adjacent support point 111, and the horizontal displacement distance L1 of the mobile trolley 10 each time it transfers the cathode plates B are all equal.

[0015] Preferably, the bracket 21 is connected to the conveyor chain 31, and a transfer suspension point 211 for suspending the cathode plate B is provided on the bracket 21. The grabbing unit 22 lifts the cathode plate B on the support point 111 and the first row of conveyor lines 1 to the transfer suspension point 211, and the grabbing unit 22 lifts the cathode plate B on the transfer suspension point 211 to the conveyor chain 31. The above two actions are performed simultaneously. More specifically, the distance L2 between the cathode plate B at the downstream end of the first row of conveyor lines 1 and its adjacent support point 111 and the distance L2 between the cathode plate B and its adjacent transfer suspension point 211 are equal. The grabbing and transferring mechanism 20 simultaneously lifts four cathode plates B each time it moves horizontally, and the above horizontal displacement distance is twice the distance L2 between two adjacent transfer suspension points 211. For the convenience of description, the direction of the horizontal displacement path of the grabbing and transferring mechanism 20 close to the first row of conveyor lines 1 is defined as the front, and the direction close to the row of conveyor lines 3 is defined as the rear. In one action cycle of the grabbing and transferring mechanism 20, the grabbing unit 22 simultaneously grabs the cathode plate on the nearest support point 111, the cathode plate B at the downstream end of the first row of conveying line 1 and the two cathode plates B on the front side of the transfer suspension point 211, and moves the four cathode plates B backward so that the three plates on the front side of the grabbing unit 22 fall onto the transfer suspension point 211, and the last cathode plate B on the back side falls onto the conveying chain 31.

[0016] Since the cathode plate B is transported and transferred by hoisting, the moving trolley 10 and the grabbing and transferring mechanism 20 need to move horizontally at a slow speed, otherwise the cathode plate B will shake violently or even fall. Under the premise of slow movement, in order to increase the transfer speed, the horizontal displacement distance of the moving trolley 10 and the grabbing and transferring mechanism 20 can only be reduced. Therefore, the support point 111 of the fixed frame 11 and the transfer suspension point 211 of the bracket 21 are set, both of which are aimed at reducing the time of a single transfer action.

[0017] In order to transport the cathode plate B smoothly and efficiently, the lifting unit 12 is two rod-shaped members arranged at equal height intervals and the coplanar surface thereof is a horizontal plane. The two rod-shaped members are arranged in the same position in the conveying direction. When the lifting unit 12 lifts the cathode plate B, the top surface of the lifting unit 12 abuts against the bottom surface of the conductive rod B' near the two rod ends; when the cathode plate B is respectively at the support point 111, the transfer suspension point 211 and the conveying chain 31, the support parts of each point abut against the bottom surface of the corresponding conductive rod B' near the two rod ends.

[0018] In order to enable the crane to lift more cathode plates B at one time, the distance L3 between the surfaces of two adjacent cathode plates B on the conveyor chain 31 is equal, and the distance L3 is smaller than the distance L2 between two adjacent transfer suspension points 211. A cylinder 32 is provided on the column conveying line 3. The rod length direction of the piston rod of the cylinder 32 is consistent with the conveying direction of the conveying chain 31. The rod end of its piston rod is connected to an extension plate 321. The extension plate 321 transfers the conductive rod B' on the transfer suspension point 211 of the adjacent column conveying line 3 to the conveyor chain 31 through the extension and contraction of the piston rod, thereby further reducing the distance between the surfaces of two adjacent cathode plates B on the conveyor chain 31.

[0019] In order to facilitate the lifting of the cathode plates B, the hangers 4 for suspending the cathode plates B on the first row of conveying lines 1 and the second row of conveying lines 2 are in an inverted "T" shape, and the cross section of the inverted "T"-shaped cross bar is in a "concave" shape. The top notches at both ends of the cross bar respectively support the ends of the conductive rods B' of the two adjacent cathode plates B.

[0020] Preferably, a supporting portion 121 in the shape of a "concave" is provided on the rod surface at the top of the lifting unit 12. When the moving trolley 10 lifts the cathode plate B, the notch at the top of the supporting portion 121 abuts against the bottom of the conductive rod B'. The moving trolley 10 is provided with a lifting cylinder 13. The piston rod of the lifting cylinder 13 is arranged in the vertical direction, and the top end of the piston rod is connected to the middle of the lifting unit 12. The bottom of the grabbing unit 22 is provided with an "L"-shaped hook 221. The rotating surface of the hook 221 is perpendicular to the rod length direction of the conductive rod B'. The grabbing and indexing mechanism 20 performs the lifting action by rotating the hook 201 to hook the bottom surface of the conductive rod B'.
