[0002] The existing conductive crossbeam of the anode plate is composed of a copper bar and a lead layer. The cross section of the copper bar is rectangular, and the lead layer is directly wrapped around the copper bar, and only the end of the copper bar, which is used for contacting the mother bar for conduction, is exposed. At present, the production of the conductive crossbeam of the anode plate is mostly carried and operated manually; however, due to the heavy weight of the copper bar and the temperature of the lead water used for casting is above 300 degrees, this traditional production method has high labor intensity, fast physical energy consumption, poor operation safety, and potential safety hazards. Not only is the production efficiency low, but the uniformity of the lead layer wrapped around the outside of the copper bar is poor, affecting product quality. In addition, the lead vapor and lead dust in the casting process are heavy metals, which pollute the environment and endanger the health of the operators. Therefore, it is necessary to improve the production method of tinning and casting of the conductive crossbeam of the anode plate in the prior art. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to improve production efficiency and operation safety, the present invention provides a production method for tinning and casting of a conductive beam of an anode plate. The production method transports a copper bar of the beam that has been pickled and cleaned by a copper bar conveying device, operates a robot to place the copper bar of the beam in a tinning furnace for tinning, operates the robot to position the tinned beam on a positioning and polishing platform to secondary correct the position of the beam lifting ear, operates the robot to place the corrected tinned beam into a casting mold, operates the robot to use a molten lead pouring tool to cast lead water on the copper bar in the casting mold, operates the robot to place the lead-cast beam on a positioning and polishing platform to cut the casting nozzle and trim the shape of the beam, and operates the robot to place the processed conductive beams on a finished beam storage vehicle. The operation steps have a high degree of automation, effectively reduce the labor intensity of the production and processing of the conductive beam of the anode plate, have good operation safety, high production efficiency, and stable product quality.

[0044] The specific steps of the present invention are described in detail. The anode plate conductive beam tinning casting production method comprises: Step 1: Place the copper bar of the beam after pickling and cleaning at the feed end of the front part of the two groups of conveyor chains of the copper bar conveying device, and the conveying motor drives the active sprocket to rotate, and drives the two groups of conveyor chains to rotate synchronously through the transmission chain, the driven sprocket and the synchronous shaft, so that the copper bar of the beam moves to the rear of the conveying device. When the photoelectric detection sensor senses the copper bar of the beam conveyed on the conveying chain, the parallel return jacking cylinders on the left and right sides are raised, and the parallel return jacking cylinders on both sides are used to stop the copper bar of the beam. After the parallel return, the parallel return jacking cylinders on both sides are retracted and the copper bar of the beam is continued to be transmitted to the rear. Afterwards, the position of the beam lug on the copper bar of the beam that has been parallel returned is sensed by the grating detection sensor, so that according to the deviation of the position of the beam lug, the lug gripper of the copper bar centering mechanism is used to center the copper bar of the beam. In addition, by arranging the copper bar stop block at the rear of the conveying direction of the conveyor chain, the copper bar of the beam that has been parallel returned and corrected for centering is positioned and stopped, so as to facilitate the grabbing of the subsequent operation robot.

[0045] At the same time, during the entire process of the crossbeam copper bar being transported on the conveying device, the baking lamp above the conveyor frame is used to dry the cleaning acid remaining on the crossbeam copper bar to avoid splashing of the subsequent crossbeam copper bar during tinning in the tinning furnace.

[0046] Step 2: After the crossbeam copper bar is moved into place on the copper bar conveying device, operate the manipulator The free end ofThe crossbeam clamping tool on the tool conversion workstation is connected to the manipulator quick-change plate, and the pressure rod connecting plate and the two sets of crossbeam clamping pressure rods thereon are driven to move downward along the pressure rod guide sleeve through the pressure rod cylinder, and then the lower end of the crossbeam clamping pressure rod is clamped with the crossbeam lifting hook to firmly clamp the crossbeam copper bar on the copper bar conveying device.

[0047] Step three, operate the robot to place the copper bar of the beam clamped on it into the tinning furnace for tinning treatment to enhance the bonding ability of copper and lead in the subsequent lead water casting process.

[0048] Step 4: Operate the manipulator to position the tinned beam on the beam positioning blocks on both sides of the positioning and polishing platform and in the narrow positioning groove at a lower position, and use the side positioning blocks to position the ends of the tinned beam, and use the rear positioning blocks to position the rear side of the middle of the tinned beam placed on the beam positioning blocks. Then, use the beam clamping cylinder to drive the beam clamping swing rod to swing, so as to press the tinned beam in the narrow positioning groove through the beam clamping block at the front end of the beam clamping swing rod. Subsequently, use the ear positioning clamping blocks set on the cylinder rod connecting blocks at the ends of the cylinder telescopic rods on both sides of the ear positioning clamping mechanism to perform secondary correction on the position of the beam lifting ears on the beam.

[0049] Step 5. After the second correction of the beam ears on the tinned beam is completed, extend the upper mold opening and closing hydraulic cylinder of the casting mold to flip the upper flip template upward relative to the bearing lower template, thereby opening the mold cavity. After that, the beam clamping mechanism of the positioning and polishing platform is released, and the manipulator is operated to position the corrected tinned beam in the lower mold casting cavity of the bearing lower template. Then, retract the upper mold opening and closing hydraulic cylinder to flip the upper flip template downward and close it with the bearing lower template; and utilize the extension and contraction of the clamping hydraulic cylinder under the bearing lower template to drive the mold clamping claw to rotate, so that the clamping part at the upper end of the mold clamping claw cooperates with the clamping claw clamping part on the flip upper template to make the closed connection between the flip upper template and the bearing lower template more secure. After the flipping upper template and the supporting lower template are closed and fastened to each other (closed casting mold), the mold flipping hydraulic cylinder 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, so that the mold pouring port of the template faces upward to facilitate the pouring of molten lead.

[0050] Step six, operate the manipulator to put the beam clamping tool back to the tool conversion workstation, and operate the free end of the manipulator to connect to the manipulator quick-change plate of the molten lead pouring tool, so as to hold the molten lead through the molten lead holding spoon at the bottom of the pouring connection block connected to the front end of the bent rod. Then, the manipulator uses the molten lead pouring tool to scoop molten lead in the lead melting furnace, and pours the molten lead into the mold cavity composed of the upper mold pouring cavity and the lower mold pouring cavity through the mold pouring port of the casting mold, and then casts the copper bar placed in the mold cavity of the casting mold with molten lead. In addition, after casting, the mold flipping hydraulic cylinder is used to control the flipping of the closed mold, so that the molten lead can fully flow in the pouring cavity and evenly wrap around the outside of the beam copper bar through the flipping movement of the mold to ensure product quality.

[0051] Step seven, when the tinned beam is cast in the closed casting mold, the mold flipping hydraulic cylinder flips the flipping upper template and the bearing lower template back to the initial horizontal arrangement position, and releases the mold fastening mechanism; then, the flipping upper template is opened upward by the upper mold opening and closing hydraulic cylinder. At the same time, the operating manipulator puts the molten lead pouring tool back to the tool conversion workstation, and the free end of the operating manipulator is connected to the beam clamping tool on the tool conversion workstation again, and then the cast-lead beam is taken out from the opened casting mold. In addition, when taking out the cast-lead beam, the casting ejection hydraulic cylinder can be extended to lift the casting ejection block in the lower mold casting cavity of the bearing lower template, thereby assisting in ejecting the beam casting upward, which is convenient for grasping and moving the cast-lead beam.

[0052] Step 8: Operate the manipulator to position the lead-cast beam on the beam positioning blocks on both sides of the positioning and polishing platform, in the higher wide positioning groove, and use the side positioning block to position the end of the lead-cast beam, and use the rear positioning block located below to assist in supporting the lead-cast beam, and use the ear positioning clamping blocks on both sides to position and clamp the beam ears, and press the lead-cast beam through the beam clamping mechanism. After that, the manipulator puts the beam clamping tool back to the tool conversion workstation again, and connects the free end of the manipulator to the manipulator quick-change disk of the nozzle cutting tool, so as to use the cutting wheel at the output end of the cutting motor on the cutting connection block to cut the casting nozzle on the lead-cast beam; the cut casting nozzle will slide into the receiving vehicle through the blanking chute.

[0053] Step nine, after the casting nozzle is cut, the free end of the operating robot is connected to the robot quick-change plate of the grinding tool on the tool conversion workstation, so as to use the grinding wheel at the output end of the grinding motor on the grinding connection block to grind and trim the shape of the conductive beam after lead casting and cutting.

[0054] Step 10. After the conductive beam is polished and trimmed, the beam clamping mechanism of the positioning and polishing platform is released, and the free end of the operating manipulator is connected to the beam clamping tool on the tool conversion workstation again, and then the processed conductive beam is placed on the finished beam storage cart.
