A vertically arranged surface grinding lifting hydraulic cylinder 78 is provided between the upper end of the surface grinding wheel lifting frame 76 and the upper part of the grinding moving frame 75; side grinding wheels 79 and a grinding wheel driving motor (such as Fig.15As shown). A feeding roller 27 is provided at the front side of the grinding body 73 for placing the cathode plate. Thus, the grinding frame drives the hydraulic cylinder 80 to drive the grinding movable frame 75 to move back and forth, and the surface grinding wheel 77 and the side grinding wheel 79 on the grinding movable frame 75 are used to grind the surface of the cathode plate 28 to be repaired or the new cathode plate and both sides of the cathode plate to grind off the oxide on the surface of the cathode plate 28 to be repaired, or to make the glue spraying part of the new cathode plate rougher and easier to glue.

[0044] In addition, the plate glue spraying device 6 includes a glue spraying machine body 81, and the plate centering mechanism 19 is arranged on both sides of the glue spraying machine body 81. A glue spraying moving frame 83 is arranged on the glue spraying machine body 81. The lower ends of the glue spraying moving frame 83 are respectively connected to the glue spraying frame moving guide rails 82 arranged on both sides of the glue spraying machine body 81 for sliding connection, and a glue spraying frame driving hydraulic cylinder 87 is arranged at the rear of the glue spraying moving frame 83. In addition, a lateral glue spraying mechanism 85 that can move laterally is arranged on the glue spraying moving frame 83, and a lateral glue spraying driving mechanism 86 is arranged between the lateral glue spraying mechanism 85 and the glue spraying moving frame 83. A longitudinal glue spraying mechanism 84 (such as Fig.16 As shown in the figure, the longitudinal glue spraying mechanism 84 and the transverse glue spraying mechanism 85 are both provided with glue spraying pumps and glue spraying nozzles. The feeding end of the glue spraying machine body 81 is provided with a feeding roller 27 for placing the cathode plate. The glue spraying frame drives the hydraulic cylinder 87 to drive the glue spraying moving frame 83 to move back and forth, and the transverse glue spraying mechanism 85 and the longitudinal glue spraying mechanism 84 on the glue spraying moving frame 83 are used to spray the glue on the liquid level of the surface of the repaired cathode plate 28 or the new cathode plate and on both sides of the cathode plate.

[0045] The feeding side of the plate degumming device 4, the plate grinding device 5 and the plate glue spraying device 6 is provided with a plate turning device 7 (such as Figure 1 As shown); it can be understood that, according to specific use needs, the plate turning device 7 can be arranged in one or more sets. The plate turning device 7 includes a turning platform, on which a turning spindle is rotatably arranged, and one end of the turning spindle is connected to a turning drive motor; a turning frame is arranged on the turning spindle, and a clamping cavity for placing the cathode plate is arranged in the middle of the turning frame, and the turning frame adopts a fork-shaped structure to avoid the various groups of plate suction cups 17 on the plate shifting device 2, so as to facilitate the taking and placing of the cathode plate on the plate turning device 7. At the same time, a loading stacking area 3 and a unloading stacking area 8 are respectively arranged below the plate shifting device 2 and at both ends of the production line.

[0046] When the cathode plate repair production line is in use, first, the cathode plate 28 to be repaired in the loading and stacking area 3 is transported face up to the workstation of the plate degumming device 4 by utilizing the adsorption and grabbing of several groups of plate suction cups 17 on the suction cup connecting frame 16 of the plate shifting device 2, and is placed flat on the plate degumming device 4 via the loading roller 27 at the front end of the degumming machine body 18, and the plate surface of the cathode plate is located below the plate clamping mechanism 20 and the liquid level line scraping part 23. Then, the centering driving hydraulic cylinder 34 of the plate centering mechanism 19 is used to drive the linkage slide rod 42 of the clamp linkage assembly 32 to move backward along the linkage guide slide rail 33, and then the left linkage link 46 and the right linkage link 47 respectively arranged at the front and rear ends of the linkage slide rod 42 are used to drive the centering clamps 30 on both sides to move oppositely (towards the middle) and synchronously, so that the clamping lateral centering parts 37 of the upper ends of the centering clamps 30 on both sides are used to center clamp the cathode plate 28 to be repaired placed on the degumming machine body 18, so as to regularize the placement of the cathode plates placed on the processing equipment, and make the colloids on both sides of the cathode plate 28 to be repaired be located at the side scraping parts 25 on both sides of the lower end of the degumming moving frame 22.

[0047] After the placement of the cathode plate 28 to be repaired is in place, the pressing rotating frame 69 is driven to rotate by the pressing driving hydraulic cylinder 72 of the plate pressing mechanism 20, and then the pressing swing arm 70 is used to press the cathode plate 28 to be repaired placed on the degumming machine body 18 below; and after the plate pressing mechanism 20 presses the cathode plate 28 to be repaired, the centering claws 30 on both sides of the plate centering mechanism 19 move in the opposite direction (towards the outside). Subsequently, the degumming frame driving hydraulic cylinder 26 is extended to drive the degumming moving frame 22 to move slowly from back to front along the degumming frame moving guide rail 21, so as to use the side degumming horizontal knife 53 and the side degumming vertical knife 54 on the side degumming part 25 on both sides of the lower part of the degumming moving frame 22, which cooperate with each other, to remove the colloid on both sides of the cathode plate. Moreover, when the liquid level line glue scraping part 23 moves to the position of the colloid at the liquid level on the surface of the cathode plate 28 to be repaired, the movement of the glue removal moving frame 22 is stopped; it can be understood that in order to remove the colloid at the liquid level as cleanly as possible, the liquid level line glue scraping part 23 can be moved forward to the front edge of the colloid at the liquid level. After that, the liquid level glue scraping lifting hydraulic cylinder 24 is extended downward to drive the liquid level line glue scraping part 23 and the liquid level line glue scraping knife 58 thereon to move downward and contact the surface of the cathode plate; then, the glue removal moving frame 22 is moved in the opposite direction or reciprocatingly, and the liquid level scraping knife blade 67 at the lower end of each liquid level line glue scraping knife 58 is used to remove the colloid at the liquid level on the surface of the cathode plate 28 to be repaired.

[0048] After the glue removal on the front side of the cathode plate 28 to be repaired is completed, the liquid level glue scraping part 23 is lifted upward, and the glue removal moving frame 22 is moved back to the initial position, the plate clamping mechanism 20 is released, the plate shifting device 2 removes the cathode plate, and moves the cathode plate 28 to be repaired (front side facing up) to the flipping frame of the plate flipping device 7, and the flipping drive motor drives the rotation of the flipping spindle to flip the cathode plate 28 to be repaired (back side facing up). After that, the plate shifting device 2 places the flipped cathode plate 28 to be repaired on the plate glue removal device 4 again to remove the glue on the other side (back side) of the cathode plate.

[0049] After the glue removal is completed, the plate shifting device 2 places the cathode plate 28 to be repaired on the plate polishing device 5, and uses the polishing frame to drive the hydraulic cylinder 80 to drive the polishing mobile frame 75 to move back and forth, and polishes the surface and both sides of the cathode plate 28 to be repaired by the surface grinding wheel 77 and the side grinding wheel 79 on the polishing mobile frame 75, thereby grinding off the oxide on the surface of the cathode plate, and making the glue spraying part of the cathode plate rougher, which is convenient for the subsequent glue hanging. Moreover, when the front side of the cathode plate 28 to be repaired is polished, the plate shifting device 2 removes the cathode plate, and moves the cathode plate 28 to be repaired to the plate turning device 7 for turning over. Afterwards, the plate shifting device 2 places the flipped cathode plate 28 to be repaired back on the plate polishing device 5, and polishes the other side of the cathode plate.

[0050] After the cathode plate is polished, the plate shifting device 2 places the cathode plate 28 to be repaired on the plate glue spraying device 6, so that the glue spraying frame drives the hydraulic cylinder 87 to drive the glue spraying mobile frame 83 to move back and forth, and the lateral glue spraying mechanism 85 and the longitudinal glue spraying mechanism 84 on the glue spraying mobile frame 83 are used to spray the colloid on the liquid level and both sides of the surface of the cathode plate 28 to be repaired. In addition, when the colloid spraying on the front of the cathode plate 28 to be repaired is completed, the plate shifting device 2 removes the cathode plate and moves the cathode plate 28 to be repaired to the plate turning device 7 again to turn it over. Then, the plate shifting device 2 puts the turned cathode plate 28 to be repaired back to the plate glue spraying device 6, and sprays the colloid on the other side of the cathode plate. The cathode plate 28 to be repaired, which has completed the three processes of scraping glue, polishing, and gluing, will be placed in the unloading stacking area 8 by the plate shifting device 2. It can be understood that the cathode plate repair production line can also be used for brand new cathode plates that do not require glue removal, that is: the plate polishing device 5 is used to make the glue spraying area of ​​the cathode plate rougher and easier to apply glue, and the plate glue spraying device 6 is used to spray the colloid on the liquid level of the plate surface and both sides; it is flexible to use and highly practical.
