Description

Technical Field

[0001] The invention belongs to the technical field of anode plate processing for wet electrolytic zinc, and in particular relates to an automated production line for tinning and casting of anode plate conductive beams. Background Art

[0002] The conductive crossbeam of the anode plate consists of a copper bar (also called a copper rod) and a lead layer. The cross section of the copper bar is rectangular, and the lead layer is directly wrapped around the copper bar. Only a small part of the copper bar end is exposed to the outside for contact with the busbar and conduction. The production of the conductive crossbeam of the anode plate includes pickling of the copper bar (deoxidation), tinning of the copper bar (the purpose is to strengthen the combination of copper and lead), casting of the copper bar with lead water in the molding cavity, and cleaning of non-standard burrs and polishing of conductive contacts after cooling and forming. At present, the transportation of copper bars in the processing process is mostly carried out manually, and some conventional conveying devices cannot adjust the position of the copper bar, which affects the grasping of the robot and is not conducive to automated production. In addition, some cleaning liquid will remain on the surface of the copper bar after pickling. When tinning in the tinning furnace later, it often causes tin water to splash and scald the operator.

[0003] Moreover, the conventional operating tools used in conjunction with the existing manipulators have poor stability in clamping the conductive beam, and cannot meet the requirements of multiple cross-processes, which is not conducive to efficient automated production. In addition, after the casting of the beam copper bar is completed, the treatment of the casting nozzle, flash burrs, conductive contacts, etc. is all done by manual positioning and operation, such as chopping the nozzle with a kitchen knife, scraping the flash burrs with a knife, and grinding the contacts on both sides with an angle grinder, and it also involves handling and turning over. This traditional method is labor-intensive and has low operating efficiency due to the heavy weight of the copper bar and the temperature of the lead water used for casting is above 300 degrees. At the same time, the existing working platform cannot adapt to the external dimensions of the beam after tinning and the beam after lead casting (beams at different processing stages) at the same time, and has poor practicality. In addition, during the movement of the copper bar during the tinning process, the position of the beam ear often shifts, and there is a lack of effective correction mechanism on the existing working platform.

[0004] In addition, the existing casting process is: the copper bar of the beam that has been tinned in advance is placed in a fixed casting cavity by manual clamping and carrying, and the cavity needs to be turned and clamped manually; at the same time, the casting of molten lead needs to rely on manual scooping of molten lead from the lead pot and then slowly pouring it into the mold cavity, and the weight of each spoonful of high-temperature molten lead (the melting point of lead is about 300 degrees Celsius) ranges from 10 to 40 kilograms, and even some conductive beams of certain structures need to be scooped twice to complete the casting. In the existing operation method, the physical energy consumption is very huge during the process of opening and closing the mold and removing the conductive beam, and the production efficiency is low. Not only does the casting time take a long time, but also, after casting, the uniformity of the lead layer wrapped around the outside of the copper bar of the beam is poor, which affects the product quality.

[0005] Therefore, it is necessary to improve the operation method and device of tinning and casting of the anode plate conductive beam in the prior art. Summary of the invention

[0006] The present invention aims at the above-mentioned problems and provides a method for adjusting the placement of the copper busbar on the conveying device.

At the same time, a flip upper template 88 is arranged above the supporting lower template 85. The left and right ends of the flip upper template 88 are movably connected to the connecting plate sliding guide columns 96 at both ends of the supporting lower template 85 through opening and closing guide connecting plates 89, and upper template opening and closing hydraulic cylinders 90 for driving the flip upper template 88 to move are also arranged between the opening and closing guide connecting plates 89 and the ends of the supporting lower template 85.

[0059] The flip upper template 88 of the casting mold 8 is composed of an upper template body 105, and an upper mold pouring cavity 106 is arranged on the lower side of the upper template body 105 (the side in contact with the lower template 85), and a mold pouring port 91 is arranged in the middle of the front side of the upper mold pouring cavity 106, and the opening and closing guide connecting plates 89 are respectively arranged on the left and right ends of the upper template body 105, and the upper end of the opening and closing guide connecting plate 89 is fixedly connected to the end of the upper template body 105, and the lower end of the opening and closing guide connecting plate 89 is movably connected to the connecting plate sliding guide column 96 at the end of the lower template 85 through the connecting plate guide groove 107; and then, through the separable assembly structure of the upper mold pouring cavity 106 of the flip upper template 88 and the lower mold pouring cavity 97 of the lower template 85, a mold cavity for subsequent lead water casting of the copper bar is formed, and it is convenient to remove the beam casting after the casting is completed.

Thus, the upper die weight reduction structure 110 is used to effectively reduce the weight of the upper die plate body 105, so as to facilitate the flexible control of the flipping upper die plate 88; at the same time, the strength of the connection structure between the upper die plate body 105 and the opening and closing guide connecting plates 89 on both sides is improved by reinforcing the connecting plates 111.

[0060] The lower mold plate 85 of the casting mold 8 is composed of a lower mold plate body 94, and a lower mold pouring cavity 97 is provided on the upper side of the lower mold plate body 94 (the side in contact with the flip upper mold plate 88), and a mold pouring port 91 corresponding to the pouring port of the upper mold pouring cavity 106 is provided in the middle of the front side of the lower mold pouring cavity 97; and a lower mold hinged ear plate 95 for hinged connection with the lower mold hinged seat 86 is provided on the lower side of the lower mold plate body 94.

At the same time, the mold cavity for subsequent lead casting of the copper bar is formed by the separable assembly structure of the lower mold casting cavity 97 carrying the lower mold plate 85 and the upper mold casting cavity 106 of the flip upper mold plate 88. In addition, the opening and closing action of the flip upper mold plate 88 is driven by the extension and contraction of the upper mold opening and closing hydraulic cylinder 90.

[0061] The left and right ends of the lower mold body 94 of the bearing lower mold 85 of the casting mold 8 and the upper part of the position hinged with the lower end of the upper mold opening and closing hydraulic cylinder 90 are respectively fixed with connecting plate sliding guide pillars 96; correspondingly, the lower part of the opening and closing guide connecting plate 89 is also provided with a connecting plate guide slot 107 for matching and connecting with the connecting plate sliding guide pillars 96. Therefore, in the process of linear extension and contraction of the upper mold opening and closing hydraulic cylinder 90, the upper mold 88 can be turned over and opened relative to the bearing lower mold 85 by using the matching guidance of the fixed connecting plate sliding guide pillars 96 and the connecting plate guide slot 107 on the opening and closing guide connecting plate 89; when the upper mold 88 and the bearing lower mold 85 are opened, the tinned crossbeam 81 is positioned and placed in the lower mold casting cavity 97; and when the upper mold 88 and the bearing lower mold 85 are closed, lead water is poured through the mold pouring port 91. In addition, two groups of casting ejection blocks 98 for ejecting the crossbeam casting are movably arranged in the lower mold casting cavity 97, and the lower ends of the casting ejection blocks 98 are respectively connected to the telescopic ends of the casting ejection hydraulic cylinders 93 arranged vertically on the lower side of the lower template body 94; and then, after the tinned crossbeam 81 is cast in the casting cavity, the casting ejection hydraulic cylinders 93 are extended to lift the casting ejection blocks 98 in the lower mold casting cavity 97, so as to assist in ejecting the crossbeam casting upward between the opened flip upper template 88 and the bearing lower template 85, so as to facilitate the subsequent grasping and moving of the crossbeam casting.

[0062] Two sets of mold fastening mechanisms 92 are provided between the bearing lower template 85 and the flip upper template 88 of the casting mold 8 to make the closure of the upper and lower templates more secure; the two sets of mold fastening mechanisms 92 are symmetrically arranged on the left and right sides of the mold pouring port 91. The mold fastening mechanism 92 includes mold fastening claws 102 located on the front and rear sides of the bearing lower template 85, and the middle of the mold fastening claws 102 is connected to the front side of the lower template body 94 of the bearing lower template 85 through the fastening claw hinge seat 103. In addition, the lower ends of the two mold fastening claws 102 at the front and rear sides and corresponding positions are connected to the telescopic ends of the fastening hydraulic cylinder 100 vertically arranged below the bearing lower template 85 through the fastening driving connecting rod 101, and the fastening hydraulic cylinder 100 is connected to the lower side of the lower template body 94 through the fastening connecting frame 99. Correspondingly, a clamping claw clamping portion 109 is respectively provided on the upper template body 105 of the flipping upper template 88 at the position in contact with the clamping portion of the upper end of each mold clamping claw 102; and then, by extending and retracting the clamping hydraulic cylinder 100 below the bearing lower template 85, the mold clamping claw 102 hinged to the clamping drive connecting rod 101 is driven to swing back and forth around the rotating axis of the clamping claw hinge seat 103, so as to utilize the clamping portion of the upper end of each mold clamping claw 102 and the clamping claw clamping portion 109 on the flipping upper template 88 to make the closed connection between the flipping upper template 88 and the bearing lower template 85 more secure, which is beneficial to the subsequent molten lead casting.

[0063] When the anode plate conductive beam tinning and casting automated production line is in use, first, the beam clamping tool 36 and the molten lead pouring tool 37 are respectively placed in the tool placement space 40 between the two groups of tool support blocks 35 of the tool conversion workstation 4, and the tool positioning pins 42 on the tool support blocks 35 are used to position the tools; then, the nozzle cutting tool 38 and the grinding tool 39 are respectively placed in the tool placement space 40 between the other two groups of tool support blocks 35, and the cutting connection block 56 and the grinding connection block 59 on the lower side of the manipulator quick change plate 44 are passed through the corresponding tool placement openings 41 on the tool carrier table 34, thereby unifying the grabbing heights of each tool, so as to facilitate the operation of the manipulator 1 to quickly and accurately grab the required tools.

[0064] Then, the copper bar 3 of the beam that has been pickled and cleaned is placed at the feeding end of the front part of the two groups of conveying chains 18 of the copper bar conveying device 2, and the conveying motor 15 drives the driving sprocket 14 to rotate, and drives the two groups of conveying chains 18 to rotate synchronously through the transmission chain 16, the driven sprocket 17 and the synchronous shaft 19, so that the copper bar 3 of the beam moves to the rear of the conveying device. When the photoelectric detection sensor 21 senses the copper bar 3 of the beam conveyed on the conveying chain 18, the parallel return lifting cylinders 22 on the left and right sides are raised, and the parallel return lifting cylinders 22 on both sides are used to stop and return the copper bar 3 to parallel position. After parallel return, the parallel return lifting cylinders 22 on both sides are retracted to continue to convey the copper bar 3 of the beam to the rear. Afterwards, the grating detection sensor 23 is used to sense the position of the beam lug 25 on the beam copper bar 3 after it has been paralleled and returned to its original position, so that the lug gripper 32 of the copper bar centering mechanism 24 can be used to center and position the beam copper bar 3 according to the deviation of the position of the beam lug 25. In addition, the copper bar stop block 20 arranged at the rear of the conveying direction of the conveying chain 18 is used to position and stop the beam copper bar 3 that has been paralleled and corrected to be centered, so as to facilitate the subsequent operation of the manipulator 1 to grab it. At the same time, during the entire process of the beam copper bar 3 being transported on the conveying device, the baking lamp above the conveyor frame 13 is used to dry the cleaning acid remaining on the beam copper bar 3 to avoid splashing of the subsequent beam copper bar 3 during the tinning process in the tinning furnace 10.

[0065] After the crossbeam copper bar 3 moves into position on the copper bar conveying device 2, the manipulator 1 is operated. The free end ofThe crossbeam clamping tool 36 on the tool conversion workstation 4 is connected to the manipulator quick-change plate 44, and the pressure rod cylinder 52 drives the pressure rod connecting plate 50 and the two groups of crossbeam clamping pressure rods 49 thereon to move downward along the pressure rod guide sleeve 51, and then the lower end of the crossbeam clamping pressure rod 49 is used to cooperate with the crossbeam lifting hook 48 to clamp the crossbeam copper bar 3 on the copper bar conveying device 2 firmly; then, the robot 1 is operated to place the crossbeam copper bar 3 clamped thereon into the tinning furnace 10 for tinning treatment to enhance the bonding ability of copper and lead in the subsequent lead water casting process. Afterwards, the robot 1 is operated to position the tinned beam 81 (conductive beam 6 in processing) on ​​the beam positioning blocks 64 on both sides of the positioning and polishing platform 5 and in the narrow positioning groove 71 at a lower position, and the end of the tinned beam 81 is positioned by the side positioning block 68, and the rear positioning block 67 is used to position the rear side of the middle of the tinned beam 81 placed on the beam positioning block 64. Then, the beam clamping cylinder 73 is used to drive the beam clamping swing rod 74 to swing, so that the tinned beam 81 in the narrow positioning groove 71 is pressed and fixed by the beam clamping pressing block 75 at the front end of the beam clamping swing rod 74. Subsequently, the position of the beam lifting lug 25 on the beam is corrected for the second time by using the lifting lug positioning clamping block 78 provided on the cylinder rod connecting block 77 at the end of the cylinder telescopic rod on both sides of the lifting lug positioning clamping mechanism 66.

[0066] After the second correction of the beam ear 25 on the tinned beam 81 is completed, the upper mold opening and closing hydraulic cylinder 90 of the casting mold 8 is extended to make the flip upper template 88 flip upward relative to the bearing lower template 85, thereby opening the mold cavity. After that, the beam clamping mechanism 65 of the positioning and polishing platform 5 is released, and the manipulator 1 is operated to position the corrected tinned beam 81 in the lower mold casting cavity 97 of the bearing lower template 85. Then, the upper mold opening and closing hydraulic cylinder 90 is retracted to make the flip upper template 88 flip downward and close with the bearing lower template 85; and the clamping hydraulic cylinder 100 below the bearing lower template 85 is used to drive the mold clamping claw 102 to rotate, so that the clamping part at the upper end of the mold clamping claw 102 is matched with the clamping claw clamping part 109 on the flip upper template 88, so that the closed connection between the flip upper template 88 and the bearing lower template 85 is more tightened. After the upper flipping template 88 and the lower supporting template 85 are closed and fastened to each other, the mold flipping hydraulic cylinder 87 is used to control the upper and lower templates in the closed state to flip upward together around the rotating axis of the lower mold hinge seat 86, so that the mold pouring port 91 of the template faces upward to facilitate the pouring of molten lead. At the same time, the operating manipulator 1 puts the crossbeam clamping tool 36 back to the tool conversion workstation 4, and the free end of the operating manipulator 1 is connected to the manipulator quick change plate 44 of the molten lead pouring tool 37 to hold molten lead through the molten lead holding spoon 55 at the lower part of the pouring connection block 54 connected to the front end of the bending rod 43, and then the copper bar placed in the mold cavity of the casting mold 8 is cast with molten lead. Then, the operating manipulator 1 uses the molten lead pouring tool 37 to scoop molten lead in the lead melting furnace 11, and pours molten lead into the mold cavity composed of the upper mold pouring cavity 106 and the lower mold pouring cavity 97 through the mold pouring port 91 of the casting mold 8. Furthermore, after casting, the mold flipping hydraulic cylinder 87 is used to control the flipping of the closed mold, so that the molten lead can fully flow in the casting cavity and evenly wrap around the outside of the crossbeam copper bar 3 through the flipping movement of the mold, thereby ensuring product quality.

[0067] After the tinned beam 81 is cast in the closed casting mold 8, the mold flipping hydraulic cylinder 87 flips the flipping upper template 88 and the bearing lower template 85 back to the initial horizontal arrangement position, and releases the mold fastening mechanism 92; then, the flipping upper template 88 is opened upward by the upper mold opening and closing hydraulic cylinder 90. At the same time, the operating manipulator 1 puts the molten lead pouring tool 37 back to the tool conversion workstation 4, and the free end of the operating manipulator 1 is connected to the beam clamping tool 36 on the tool conversion workstation 4 again, and then the lead-cast beam 82 is taken out from the opened casting mold 8. In addition, when taking out the lead-cast beam 82, the casting ejection hydraulic cylinder 93 can be extended to lift the casting ejection block 98 in the lower mold casting cavity 97 of the bearing lower template 85, thereby assisting in ejecting the beam casting upward, which is convenient for grabbing and moving the lead-cast beam 82.

[0068] Subsequently, the robot 1 is operated to position the cast-lead beam 82 (the conductive beam 6 being processed) on the beam positioning blocks 64 on both sides of the positioning and polishing platform 5 and in the higher wide positioning groove 72 (after cast-lead, the width of the beam increases), and the end of the cast-lead beam 82 is positioned by the side positioning block 68, and the rear positioning block 67 located below is used to assist in supporting the cast-lead beam 82, and the ear positioning clamping blocks 78 on both sides are used to position and clamp the beam ears 25, and the beam clamping mechanism 65 is used to press and fix the cast-lead beam 82.
