[0021] The following further detailed description of the utility model will be given in conjunction with the accompanying drawings and specific embodiments.

[0022] Figures 1 to 4Among them, a head-mounted bracket automatic gate-cutting device includes a rotary suction cup mechanism and a gate-cutting mechanism. The rotary suction cup mechanism includes a manipulator jig 10. The gate-cutting mechanism includes a horizontally fixed plate 22 and a vertically fixed plate 21 fixedly connected. The top of the vertically fixed plate 21 is fixedly connected with a top fixed plate 20. At both ends of the vertically fixed plate 21, a pair of scissors is provided respectively, and a push cylinder 40 is fixedly connected to the bottom side wall. At one end of the push cylinder 40, a universal joint 41 is provided, and the universal joint 41 is fixedly connected with a lower movable tool holder 51. At both ends of the horizontally fixed plate 22, a first positioning pin 212 is inserted respectively. The manipulator jig moves the gate to the scissors and rotates for adjustment, and the push cylinder 40 pushes the scissors to cut off the gate 101.

[0023] The current automatic gate-cutting jig adopts single-edge longitudinal cutting. Under the same conditions, only one-third of the shearing force of transverse cutting is required for longitudinal cutting to complete the shearing action, and there will be no problem of blade bruising, so as to reduce the probability of tool damage. The cutting tool is designed in a small-batch processing method, which can greatly reduce the subsequent tool purchase cost. The cutting force of the tool is designed to be 18KGf, the hardness is HRC60-65, and the service life is more than 200,000 times.

[0024] The scissors include a fixed tool holder 52, and an upper movable tool holder 50 movably connected to the fixed tool holder 52 through a needle bearing 55. The bottom end of the upper movable tool holder 50 is fixedly connected with a lower movable tool holder 51. The lower movable tool holder 51 is fixedly connected with a positioning screw 53, and the positioning screw 53 abuts against the fixed tool holder 52. The fixed tool holder 52 is fixedly connected with the vertically fixed plate 21. The top end of the upper movable tool holder 50 is fixedly connected with a movable blade 501 through a second positioning pin 503, and the second positioning pin 503 abuts against the fixed tool holder 52 through a first spring 502. At the top end of the fixed tool holder 52, a fixed knife 521 is provided. On both side walls of the fixed knife 521, a first brace 522 and a second brace 524 are fixedly connected respectively. The first brace 522 is provided with an installation hole 523. A gate 101 is arranged between the movable blade 501, the fixed knife 521, the first brace 522 and the second brace 524. The installation hole 523 is fixedly connected with a laser sensor. The laser sensor detects whether there is a gate in the scissors.

[0025] At both top ends of the top fixed plate 20, a guide post 23 is provided respectively, and a second spring 24 is sleeved on the guide post 23. At both ends of the vertically fixed plate 21, a convex block 211 is provided respectively, and the convex block 211 is inserted into the first positioning pin 212. The first positioning pin 212 and the positioning screw 53 limit the movement range of the upper movable tool holder 50.

[0026] To facilitate the clamping and micro-adjustment of the gate 101, thereby facilitating the automatic removal of the gate, two sets of suction cup adjustment blocks 15 are provided at both ends of the manipulator jig 10. The suction cup adjustment blocks 15 are successively provided with a first suction cup 151 and two second suction cups 152 from top to bottom. One end of the first suction cup 151 is fixedly connected to an adjustment cylinder 12. The first suction cup 151 and the second suction cups 152 are suction-connected to a head-mounted bracket 100. A gate body 102 is provided between the two head-mounted brackets 100. One gate 101 is provided at each end of the gate body 102. The manipulator jig 10 is provided with a positioning plate 11. Two strip-shaped holes 112 are provided at one end of the positioning plate 11. A perforation 111 is provided at one end of the strip-shaped holes 112. An angled fixing plate 121 is fixedly connected between the two strip-shaped holes 112 of the positioning plate 11. The two sides of the strip-shaped holes 112 are fixedly connected to the suction cup adjustment blocks 15. The angled fixing plate 121 is fixedly connected to the adjustment cylinder 12. The top end of the adjustment cylinder 12 is fixedly connected to a suction cup push-pull plate 13. The suction cup push-pull plate 13 is fixedly connected to the first suction cup 151. The adjustment cylinder 12 finely adjusts the first suction cup 151 through the suction cup push-pull plate 13, thereby finely adjusting the position of the gate 101 between the movable blade 501 and the fixed blade 521. A linear bearing 113 is inserted into the perforation 111. The linear bearing 113 abuts against the guide post 23 under the drive of the manipulator. The linear bearing 113 is fixedly connected to the positioning plate 11. A square hole 115 is provided between the two horizontal strip-shaped holes 112. A gate clamp 30 of the gate 101 is inserted into the square hole 115. The adjustment cylinder 12, the laser sensor and the push cylinder 40 are electrically connected to the controller. When the laser sensor detects the gate, the controller controls the adjustment cylinder 12 to adjust the gate and controls the push cylinder 40 to drive the movable blade 501 to cut off the gate.

[0027] The product is adsorbed and taken out of the mold by the manipulator vacuum suction cup, transferred to the corresponding position of the automatic gate shearing jig, and the product is slightly pressed. After the laser sensor of this automatic gate shearing jig detects the gate, the CDU20-10D push cylinder is started to shear the gate. Then, after a 2S delay, the manipulator together with the finished product moves upward, transfers the finished product to the production line, and flows into the packing process. Then, the above process is repeated.

[0028] For this automatic gate-cutting jig, a deviation allowance of 2 mm to 4 mm is reserved on the front, rear, and right sides for the "head-mounted bracket product". The "gate" first enters the "double-profile positioning block" for correction in two directions, front and back. The deviation between the "gate" and the "fixed knife" is less than 0.5 mm, which is the biggest bottleneck for positioning and also the biggest risk point in this automatic solution. Cleverly, the "product" is longitudinally rotated counterclockwise by 5° to 8° through the manipulator vacuum chuck, and the deviation between the left side of the "product" and the "fixed knife" directly increases by 2 mm to 3 mm. Then, the posture of the product during the longitudinal positioning process continues to descend, effectively solving the positioning bottleneck problem where the left side is less than 0.5 mm. When the left side of the "product" encounters the diagonal brace, i.e., the "double-profile positioning block", after the left side of the "double-profile positioning block" is blocked in contact, it then rotates clockwise under the guidance of the right-side inclined plane until the inner bottom surface of the "product" fits the right-side top surface of the "double-profile positioning block". After the linear bearing of the manipulator jig is concentrically fitted with the "positioning pin" on the "fixed plate", it starts to descend in a relatively slow manner. Relying on the inclined planes of the "fixed knife" and the "double-profile positioning block", the "product" is positioned horizontally and longitudinally in sequence until the "product" is completely aligned. The inner surface of the "product" completely wraps the upper part of the "double-profile positioning block" until the bottom surface of the "product" fits the top surface of the "double-profile positioning block", and the positioning of the "product" is completed. This positioning method is accurate and can reduce damage to the outer surface of the "product". During the process of removing the "gate", the force-bearing surfaces are the top surfaces of the fixed knife and the double-profile positioning block. The CDU20-10D cylinder drives the movable tool holder to move in a counterclockwise circular tangent motion with a pushing force of 18 KGf, and the radius of the arc is 100 mm. The edge of the "blade" is an arc-shaped edge with a radius of 22 mm, and the taper of the upper and lower cutting surfaces of the edge is 28 degrees. It moves along an arc with a radius of 100 mm following the "tool holder" to complete the task of cutting the "gate". The manipulator descends and stops when the "product" fits the "double-profile positioning block". To prevent misoperation, once the manipulator descends beyond the stroke, the second spring here prevents the manipulator from continuing to descend in advance to trigger the overload protection of the manipulator as soon as possible.

[0029] The above are only specific application examples of the present utility model and do not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the rights protection of the present utility model.
