As shown in fig. 1 to 7, by practice, the present inventors provide an automated parts welding and boxing apparatus including a feeding part 100, a projection welder 200, a feeding robot 300, a finished product transfer rail 400, a finished product box 500, and a discharging part 600.
Wherein, material loading department 100 is used for placing the part that waits to carry out welding process. One end of the finished product transfer rail 400 faces the projection welder 200, and the finished product bin 500 is located at the other end of the finished product transfer rail 400.
The feeding robot 300 is disposed beside the projection welder 200, and the feeding robot 300 includes a gripper 310, and the gripper 310 is configured to be movable between the feeding place 100 and the projection welder 200.
The projection welder 200 includes a first electrode 210 and a second electrode 220 arranged in a vertical direction, the first electrode 210 being positioned above the second electrode 220.
The discharging part 600 includes a telescopic bar 610, and the telescopic bar 610 is disposed between the feeding part 100 and the projection welder 200. One end of the telescopic rod 610 in the length direction faces one end of the second electrode 220 close to the first electrode 210, and the discharging part 600 is configured to be able to extend by driving the telescopic rod 610 to eject the part located on the second electrode 220 into the finished product conveying track 400.
In the embodiment of the present disclosure, the automatic part welding and boxing apparatus first uses the gripper 310 of the feeding robot 300 to grip the part at the feeding position 100, and the gripper 310 conveys the part to the second electrode 220 of the projection welder 200 in the standby state. After the gripper 310 releases the grip of the part, the part is welded together with the second electrode 220 by operating the first electrode 210 of the projection welder 200 to move downward. After the welding is completed, the first electrode 210 is raised, and the projection welder 200 returns to the standby state again. And simultaneously, the processed parts are ejected into the finished product transfer rail 400 located at the opposite side of the projection welder 200 by controlling the extension of the telescopic bar 610 of the discharging part 600. After a plurality of welding processes, the finished parts pushed into the finished product conveying rail 400 sequentially push the finished products previously entering the finished product conveying rail 400, so that the finished parts are conveyed into the finished product box 500 at the other end of the finished product conveying rail 400 one by one through the finished product conveying rail 400, and the automatic boxing of the finished parts is completed. After the part to be processed is grabbed and conveyed to the second electrode 220 from the feeding part 100 through the grabber 310, the grabber 310 can directly move back to the feeding part 100 to grab a new part to be processed, the grabbing and conveying of the finished part to the finished box 500 for boxing are not needed after welding is completed, the working time of the feeding robot 300 in the welding and boxing cycle of each part is effectively reduced, and therefore the welding processing and boxing efficiency of the part is improved.
Exemplarily, in the embodiment of the present disclosure, the time for grasping the part from the feeding site 100 by the grasping hand 310 of the feeding robot 300 is 2 s; the moving time for conveying the grabbed parts to the projection welding machine 200 is 1.5 s; the time for welding the parts by the first electrode 210 and the second electrode 220 of the projection welder 200 is 1.5S (wherein the up and down time of the first electrode 210 is 0.5, and the welding time is 1S), the time for transferring the final finished parts from the finished product transfer rail 400 to the finished product bin 500 is 0.5S, and the time for moving the gripper 310 back to the loading position 100 by the projection welder 200 is 0.5S. In the welding and boxing method of the related art, the time required for the finished parts to be picked up by the projection welder 200 and transferred to the finished box 500 by the hand grip 310 and then moved back to the loading position 100 is 2S. That is, the working time of the gripper 310 of the feeding robot 300 in the welding processing cycle of each part is saved by 1.5s, and the welding processing and boxing efficiency of the parts are effectively improved while the welding and boxing of each part are ensured.
Optionally, an end of the finished product transfer track 400 near the projection welder 200 is vertically higher than an end of the finished product transfer track 400 near the finished product bin 500. Illustratively, in the embodiment of the present disclosure, by setting an end of the finished product conveying track 400 close to the projection welder 200 higher than an end of the finished product conveying track 400 close to the finished product box 500 in the vertical direction, that is, the finished product conveying track 400 is inclined from the projection welder 200 to the direction of the finished product box 500. Finished parts jacked into the finished product conveying rail 400 by the telescopic rod 610 automatically slide into the finished product box 500 under the action of gravity, so that the finished parts can be automatically boxed more quickly, and the boxing efficiency is further improved.
Optionally, the finished product conveying track 400 is provided with baffles 410 at two opposite sides in the extending direction. For example, since there may be some size deviation between different parts, the direction and the movement track of the part ejected into the finished product conveying track 400 may be different after being pushed by the retractable rod 610. The baffle plates 410 are arranged on the two opposite side edges of the finished product conveying rail 400 in the extending direction, so that the baffle plates 410 can limit and guide finished product parts with deviation in the sliding direction, the finished product parts are prevented from sliding out of the finished product conveying rail 400 from the two opposite side edges of the finished product conveying rail 400, and the stability of boxing is guaranteed.
Alternatively, the blocking plate 410 is rotatably connected to the finished product conveying rail 400 by a rotating shaft 411, and the rotating shaft 411 is parallel to two opposite sides of the finished product conveying rail 400 in the extending direction. For example, in the embodiment of the disclosure, most of the finished parts pushed into the finished product conveying track 400 may move into the finished product box 500 under the push of the subsequently pushed-in finished parts, but the finished parts finally entering the finished product conveying track 400 may stay in the finished product conveying track 400 due to insufficient power. At this moment, the worker can rotate and spread the baffle plates 410 on one side or two sides towards the direction far away from the baffle plate 410 on the other side by adjusting the baffle plates 410 on two sides, so that the worker can conveniently take out the remaining finished parts staying in the baffle plates from two sides of the finished product conveying track 400, the final boxing work can be rapidly completed, and the boxing efficiency is further improved.
Optionally, the finished product conveying track 400 includes a plurality of driving wheels 420 and a conveying belt 430, the plurality of driving wheels 420 are arranged at intervals along the length direction of the finished product conveying track 400, the conveying belt 430 is wound around the plurality of driving wheels 420, and the axial direction of the plurality of driving wheels 420 is perpendicular to the length direction of the finished product conveying track 400. Illustratively, in another possible implementation, the wrap around conveyor belt 430 is driven to rotate by a drive wheel 420. After the finished parts are ejected into the finished product conveying track 400, the finished parts can be directly conveyed into the finished product box 500 along with the conveying belt 430 without the help of gravity and manual operation, and the box packing efficiency is further improved.
Optionally, an elastic buffer layer 431 is provided on the outer surface of the transfer belt 430. Illustratively, in the disclosed embodiment, an elastic buffer layer 431, such as a rubber buffer layer, is provided on the outer surface of the conveyor belt 430. When the finished parts are ejected into the finished product conveying track 400 and fall onto the conveyor belt 430, the rubber buffer layer can absorb and buffer the stress generated by the collision, so as to avoid collision and abrasion of the finished parts. Meanwhile, the static friction between the rubber and the parts is improved, the finished parts are prevented from sliding relative to the conveying belt 430 due to vibration and the like in the conveying process, the finished parts are prevented from falling off from the finished product conveying rail 400, and the boxing stability of the automatic part welding and boxing device is improved.
Optionally, the telescoping rod 610 is a pneumatically telescoping rod. Illustratively, in the embodiment of the present disclosure, compared with a hydraulic telescopic rod, a pneumatic telescopic rod, that is, a jacking cylinder, is used to push the finished parts. The structure is simple, and the device can work normally in high-temperature and low-temperature environments. Meanwhile, the pneumatic element is adopted for power supply, and compared with the method of using a hydraulic cylinder for power supply, the device has the advantages of smaller occupied volume and easiness in installation and maintenance.
Optionally, the automated part welding and boxing apparatus further comprises a blowing unit 620, a blowing direction of the blowing unit 620 faces to an end of the second electrode 220 close to the first electrode 210, and the discharging unit 600 is configured to blow the parts on the second electrode 220 into the finished product conveying rail 400 through the blowing unit 620. For example, in the embodiment of the present disclosure, depending on the size of the part to be processed, after the welding process of the small part is performed, the finished part may be discharged by blowing using the blowing unit 620; and after the medium-sized parts with larger sizes are welded, the telescopic rod 610 is used for pushing and discharging. The operation energy consumption of the automatic part welding and boxing device can be effectively reduced, and the processing cost is reduced.
Optionally, the automated parts welding and boxing apparatus further comprises a positioning pin 230, the end surface of the second electrode 220 close to the first electrode 210 is provided with a mounting groove 221 extending along the vertical direction, and the positioning pin 230 is telescopically mounted in the mounting groove 221. Illustratively, in the embodiment of the present disclosure, when the projection welder 200 does not perform the welding process, the positioning pin 230 is retracted and disposed in the mounting groove 221, so as to ensure that the end surface of the second electrode 220 is flat, and facilitate the hand grip 310 to place the unprocessed part on the end surface of the second electrode 220. And then the positioning pin 230 is controlled to extend out of the mounting groove 221 and go deep into a screw hole on the part to be welded to coaxially position the part, so that the part cannot fall off from the projection welding machine 200 during welding. After the welding is completed, the positioning pin 230 is retracted into the mounting groove 221 again, so that the discharging part 600 can conveniently push the finished parts into the finished product conveying rail 400. By providing the retractable positioning pin 230, the precision and stability of the part during the welding process are improved.

After the gripper 310 releases the grip of the part, the part is welded together with the second electrode 220 by operating the first electrode 210 of the projection welder 200 to move downward. After the welding is completed, the first electrode 210 is raised, and the projection welder 200 returns to the standby state again. The finished parts are ejected into the finished product transfer rail 400 located at the opposite side of the projection welder 200 by controlling the extension of the telescopic bar 610 of the discharging part 600. After a plurality of welding processes, the finished parts pushed into the finished product conveying rail 400 sequentially push the finished products previously entering the finished product conveying rail 400, so that the finished parts are conveyed into the finished product box 500 at the other end of the finished product conveying rail 400 one by one through the finished product conveying rail 400, and the automatic boxing of the finished parts is completed. After the part to be processed is grabbed and conveyed to the second electrode 220 from the feeding part 100 through the grabber 310, the grabber 310 can directly move back to the feeding part 100 to grab a new part to be processed, the grabbing and conveying of the finished part to the finished box 500 for boxing are not needed after welding is completed, the working time of the feeding robot 300 in the welding and boxing cycle of each part is effectively reduced, and therefore the welding processing and boxing efficiency of the part is improved.
