Further, a folded lug 623 folded upward is integrally formed on the auxiliary suction portion 62. In a specific implementation process, the folding lug 623 is provided with a sleeve hole 6231 penetrating through the body thereof. During the processing, the suction nozzle can realize the stable suction and positioning of the material 63 (especially small-sized workpieces) through the auxiliary suction part 62.
Referring next to fig. 6 to 9, there is shown a break-off assembly 25 for breaking off the auxiliary extraction portion 62 from the material 63, the break-off assembly 25 comprising:
a lift drive (not shown);
a break-off mounting plate 251 which is in transmission connection with the power output end of the lifting driver;
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253 to move toward or away from the fixed finger 252 so that the break-off penetrating rod 2542 is inserted into or withdrawn from the break-off accommodating cavity 255.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, after the material 63 is processed, the material 63 is placed under the breaking assembly 25, so that the tab 623 is opposite to the break accommodating chamber 255 and is located right below the break accommodating chamber 255, the lifting driver drives the break mounting plate 251 to descend, so that the tab 263 is received by the break accommodating chamber 255, and at least part of the through hole 6231 is sunk into the break accommodating cavity 255, then the pushing driver 253 drives the sliding finger 254 to approach the fixed finger, the break through rod 2542 enters the break accommodating cavity 255 and then passes through the through hole 6231 to make the break lug 623 penetrate through the break through rod 2542, the elevating driver then drives the break mounting plate 251 to reciprocate up and down in a vertical plane, referring to fig. 4, since the material 63 is fixed, the auxiliary suction portion 62 can only perform the reciprocating bending motion around the material 63 along the arrow a and the arrow B with the broken indentation 631 as a boundary line, and finally the auxiliary suction portion 62 is separated from the material 63. By adopting the technical scheme with the characteristics, the folding lug 623 is sleeved on the breaking sleeve penetrating rod 2542 in a penetrating way, so that in the process of breaking the folding lug 623, the folding lug 623 can weaken or die a transverse shearing force generated in the breaking process through reciprocating sliding along the breaking sleeve penetrating 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 623 are prevented, the welding yield is improved, and the production cost is reduced.
Referring again to fig. 7 or 8, the snap-off receiving grooves 255 are generally in an inverted U-shaped configuration to form 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-off sleeve rod 2542 is inserted into the break-off accommodating cavity 255 after passing through the rear sidewall 2521 and is at least partially submerged into the front sidewall 2522 or is pulled out of 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 open angle from the top of the snap receiving 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. 9 and 10, 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. 6, 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. 8 and 9 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. 8 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 suction portion 62 to be detached from the material 63, and also includes irreversible damage to the material 63 in the form of loosening of the welding point, cracking of the welding seam, deformation of the workpiece, damage to the welding base, and the like, although the auxiliary suction portion 62 is detached from the material 63.
Referring to fig. 1, the cutting indentation 613 and the breaking indentation 631 have a thinner thickness dimension than the auxiliary suction portion 62. In a specific implementation, the cutting indentation 613 and the breaking indentation 631 are made by pressing easy-to-tear grooves on the upper and lower surfaces of the auxiliary suction portion 62.
Furthermore, the easy-tearing groove is at least one of a V-shaped groove, a U-shaped groove and a semicircular groove. In one embodiment, the easy-tear groove is a V-shaped groove.
