According to an embodiment of the present invention, as can be seen from the illustration of fig. 4, the workpiece 26 includes a workpiece body 261 and an auxiliary material 262 connected to the workpiece body 261, an upward folded tab 263 is integrally formed on the auxiliary material 262, a through hole 2631 is formed on the tab 263, and a fold 264 which is easily broken is formed at a connection position of the workpiece body 261 and the auxiliary material 262. The welding suction nozzle can suck and position the workpiece 261 (particularly small-size workpieces) stably by sucking the auxiliary material 262 in the welding process, and one of the purposes of the invention is to break the auxiliary material 262 from the workpiece 26 along the crease 264 so as to separate the auxiliary material 262 from the workpiece body 261 and reduce the deformation influence on the workpiece body 261 as much as possible in the separation process.
According to an embodiment of the present invention, as shown in fig. 1 to 3, it can be seen that the auxiliary material breaking mechanism 25 includes:

an adjusting plate 256 fixedly connected with the lifting plate 258;
a rotating disc 257, which is rotatably connected to the adjustment disc 256; and
a break-off assembly fixedly connected to the rotary disc 257,
the rotating disc 257 is coaxially and rotatably connected to the center of the adjusting disc 256; at least three adjusting through holes 2561 arranged along the circumferential direction of the adjusting disc 256 are formed in the adjusting disc 256, and an unlocking through hole 2562 is formed between every two adjacent adjusting through holes 2561; the rotational angle adjustment between the rotary plate 257 and the adjustment plate 256 is achieved by screwing or unscrewing a locking bolt in each unlocking through hole 2562.
Further, the lifting plate 258 is fixedly connected to the edge of the adjusting plate 256. By adopting the structure, the connection stability of the lifting plate 258 and the adjusting disc 256 can be enhanced, and the lifting plate 258 can be prevented from blocking or interfering the unlocking through hole 2562 and the adjusting through hole 2561 on the rotating disc 257, so that the adjustment convenience is improved.
Further, the breaking-off component is fixedly connected to the bottom of the rotating disc 257.
Referring next to fig. 5-8, it can be seen that the break assembly comprises:
a break-off mounting plate 251 fixedly connected to the lifting plate 258;
a pushing actuator 253 mounted on the break mounting plate 251;
a rod-shaped fixing finger 252 fixedly connected to the break-off mounting plate 251 and downwardly depending from the break-off mounting plate 251; and
a rod-shaped sliding finger 254 drivingly connected to the power output end of the ejector driver 253 and depending downwardly from the ejector driver 253;
wherein the breaking mounting plate 251 is driven by the lifting driver to lift and descend in a vertical plane in a reciprocating manner; the bottom of the fixed finger 252 is opened to form a break accommodating cavity 255; the sliding finger 254 is arranged opposite to the fixed finger 252, and a broken sleeve penetrating rod 2542 is fixedly connected to the side surface of the sliding finger 254 opposite to the fixed finger 252; the sliding finger 254 is driven by the pushing driver 253 to move toward or away from the fixed finger 252 so that the break-off penetrating rod 2542 is inserted into or withdrawn from the break-off accommodating cavity 255. Referring to fig. 8 and 9, when the workpiece 26 is welded, the workpiece 26 is placed under the break-off assembly 25, such that the folded lug 263 is opposite to the break-off containing cavity 255 and is located right below the break-off containing cavity 255, the lifting driver drives the break-off mounting plate 251 to descend, such that the folded lug 263 is received by the break-off containing cavity 255, and at least a portion of the through hole 2631 is sunk into the break-off containing cavity 255, then the pushing driver 253 drives the sliding finger 254 to approach the fixed finger, the break-off penetrating rod 2542 enters the break-off containing cavity 255 and passes through the through hole 2631, such that the folded lug 263 penetrates the break-off penetrating rod 2542, and then the lifting driver drives the break-off mounting plate 251 to reciprocate in a vertical plane, referring to fig. 5, since the workpiece body 261 is fixedly welded on the welding substrate, the auxiliary material 262 can only make a reciprocating bending motion around the workpiece body 261 with the fold 264 as, eventually separating the auxiliary material 262 from the workpiece body 261. By adopting the technical scheme of the characteristic, the folding lug 263 is sleeved on the breaking sleeved rod 2542 in a penetrating way, so that in the process of breaking the folding lug 263, the folding lug 263 weakens or disappears the transverse shearing force generated in the breaking process through reciprocating sliding along the breaking sleeved rod 2542, the problems of welding point falling, welding line cracking, workpiece deformation and the like caused by overlarge bending force applied to the folding lug 263 are prevented, the welding yield is improved, and the production cost is reduced.
Referring again to fig. 8 or 9, the break accommodating grooves 255 are formed in a substantially inverted U-shaped configuration to be in opposite positions:
a front sidewall 2522 distal to the fixed fingers 252; and
a rear sidewall 2521 opposite the fixed fingers 252;
wherein the sliding finger 254 is driven by the pushing driver 253 to move toward or away from the fixed finger 252 so that the break-through stem 2542 is inserted into the break-off accommodating cavity 255 through the rear sidewall 2521 and at least partially submerged into the front sidewall 2522 or withdrawn from the break-off accommodating cavity 255.
Further, the front sidewall 2522 and the rear sidewall 2521 extend parallel to each other or at least approximately in a vertical direction with an opening angle from the top of the fracture accommodating groove 255. With this structure, the folded lug 263 can be prevented from scraping against the front sidewall 2522 or the rear sidewall 2521 during the process of entering the break accommodating groove 255, so that the success rate of the folded lug 263 entering the break accommodating groove 255 is improved, and the folded lug 263 is prevented from being blocked and deformed during the process of entering the break accommodating groove 255.
Referring to fig. 10 and 11, the rear sidewall 2521 is provided with a first through hole 2524 extending through the front and rear portions thereof, and the front sidewall 2522 is provided with a second through hole 2525 extending through the front and rear portions thereof; when the sliding finger 254 is driven by the pushing driver 253 to approach the fixed finger 252, the break-off sleeve rod 2542 sequentially passes through the first sleeve hole 2524 and the break-off accommodating groove 255 and then at least partially sinks into the second sleeve hole 2525. The second through hole 2525 may be configured to close the front end of the break-away stem 2542 to prevent the folded ear 263 from slipping off the front end of the break-away stem 2542 during the bending process.
Further, the first loophole 2524 has a hole size adapted to the radial size of the break-off looper 2542; the second through hole 2525 has a bore diameter which is greater in the vertical direction than the radial dimension of the break-off through rod 2542, and the second through hole 2525 has a bore diameter which is adapted to the radial dimension of the break-off through rod 2542 in the horizontal direction. With this structure, the break-off sleeving rod 2542 can rotate at a small angle relative to the root of the break-off lug 263 after being pulled by the break-off lug 263 during the bending process, which helps to buffer the impact force received by the break-off lug 263 during the bending process, and further prevents the problems of welding point falling, welding seam cracking, workpiece deformation and the like caused by excessive bending force applied to the break-off lug 263.
Referring to fig. 7, the dimension of the second penetration hole 2525 in the vertical direction is defined as H, and the radial dimension of the broken penetration rod 2542 is defined as D, so that H: D is 1.1-2.5. In a specific embodiment, H: D is preferably 2.
Referring to fig. 9 and 10 again, a guide hole 2523 is formed on a side surface of the fixed finger 252 opposite to the sliding finger 254, a guide rod 2541 opposite to the guide hole 2523 is fixedly connected to the sliding finger 254, and an extending direction of the guide hole 2523 is parallel to a sliding direction of the sliding finger 254; when the sliding finger 254 is driven by the pushing driver 253 to approach the fixed finger 252, the guide rod 2541 is at least partially inserted into the guide hole 2523. The guiding hole 2523 and the corresponding guiding rod 2541 are configured to enable the sliding finger 254 to approach the fixed finger 252 smoothly under the driving of the pushing driver 253, and also to improve the accuracy of the engagement of the broken penetrating rod 2542 into the second penetrating hole 2525.
Referring to fig. 9 again, the front side of the sliding finger 254 is fitted to the rear side of the fixed finger 252, and the sliding finger 254 is driven by the pushing driver 253 to approach the fixed finger 252 until the front side of the sliding finger 254 is fitted to the rear side of the fixed finger 252. By adopting the technical scheme of the characteristics, the matching tightness of the sliding finger 254 and the fixed finger 252 can be improved, and the fracture failure caused by the dislocation of the sliding finger 254 and the fixed finger 252 in the bending process can be prevented.
It should be understood that the term "failure to break" as used herein includes, but is not limited to, failure of the auxiliary material 262 to be detached from the workpiece body 261, and also includes irreversible damage to the workpiece body 261 such as loosening of the weld, cracking of the weld, deformation of the workpiece, damage to the weld base, etc., which may occur while the auxiliary material 262 is detached from the workpiece body 261.
The number of apparatuses and the scale of the process described herein are intended to simplify the description of the present invention. Applications, modifications and variations of the present invention will be apparent to those skilled in the art.
