[0016] See attached document Figure 1-16 The present invention provides a more detailed description of an automatic parts handling system for hardware products.

[0017] An automatic part-picking system for hardware products includes a frame 1, on which a waste removal device 2 and two oppositely arranged material-folding and part-picking devices 3 are provided, wherein a transfer robot 4 is provided between the waste removal device 2 and the two material-folding and part-picking devices 3. When processing the hardware parts 8, the waste removal device 2 automatically deburrs the hardware parts 8. Then, the transfer robot 4 transfers the hardware parts 8 that have been deburred 81 to the two folding and picking devices 3. The two folding and picking mechanisms work together to fold the two hardware parts 8 off the connecting piece 82, so that the connecting piece 82 between the two hardware parts 8 is separated from the hardware parts 8, realizing the rapid separation operation of the hardware part 8 blank; replacing manual operation, improving the processing efficiency of the hardware parts 8, and effectively reducing production costs.

[0018] The waste removal device 2 includes a placement rack 21 for placing hardware parts 8 and a waste removal component 22 disposed above the placement rack 21. The waste removal component 22 includes a waste removal cylinder 221 and a mounting frame 222 connected below the waste removal cylinder 221. The mounting frame 222 has a plurality of push rods 223 spaced apart at its lower end, and the push rods 223 are correspondingly disposed to the burrs 81 of the hardware parts 8. The waste removal cylinder 221 pushes the mounting frame 222 downward, causing the push rods 223 to press down on the corresponding burrs 81 on the hardware parts 8, so that the burrs 81 are separated from the hardware parts 8. This achieves rapid and efficient waste removal processing of the burrs 81 of the hardware parts 8, replacing manual deburring operations, improving processing efficiency, and effectively reducing the production cost of the hardware parts 8.

[0019] The placement rack 21 is provided with a first waste material discharge channel 11, into which the burrs 81 processed and removed by the waste removal device 2 fall; the folding and picking device 3 is provided with a second waste material discharge channel 12, into which the connecting parts 82 processed and removed by the folding and picking device 3 fall; and the waste materials are collected and reused.

[0020] The placement rack 21 is provided with a positioning post 23 below it. The positioning post 23 is provided with a positioning spring 231 and a lower positioning rod 232 from bottom to top. The positioning spring 231 causes the upper end of the lower positioning rod 232 to pass through the positioning post 23. The lower end face of the mounting bracket 222 is provided with an upper positioning rod 224 corresponding to the lower positioning rod 232; The waste removal cylinder 221 drives the mounting bracket 222 to move downward, so that the upper positioning rod 224 and the lower positioning rod 232 cooperate to clamp the hardware 8 and position the hardware 8 to be processed; to prevent the hardware 8 from shaking during the deburring process 81 by pressing down the waste removal component 22, so that the top rod 223 can accurately align with the burr 81 of the hardware 8 and press down, so that the burr 81 can be accurately separated from the hardware 8.

[0021] The lower end of the placement rack 21 is provided with a support frame 24, and the support frame 24 is mounted on the frame 1 by a support assembly 25; The support assembly 25 includes a support rod 251 and a support spring 252 sleeved on the support rod 251. The lower end of the support rod 251 is fixed to the frame 1, and the upper end passes through the support frame 24. The lower end of the support spring 252 abuts against the support rod 251, and the upper end abuts against the lower end face of the support frame 24, thus supporting the support frame 24. By supporting the support frame 24 through the support spring 252, when the vibrator 26 vibrates the placement frame 21, the support spring 252 can play a vibration damping role on the placement frame 21, so that the placement frame 21 can stop vibrating in time and quickly carry out the next waste removal processing operation.

[0022] The support frame 24 is provided with a left slide groove 241 and a right slide groove 242 on its left and right sides, respectively. The placement rack 21 includes a front support 211 and a rear support 212 arranged opposite to each other. The left support legs 213 of the front support 211 and the rear support 212 are slidably disposed in the left slide groove 241, and the right support legs 214 of the front support 211 and the rear support 212 are slidably disposed in the right slide groove 242. The front support 211 and the rear support 212 can slide relative to each other along the left slide groove 241 and the right slide groove 242, adjusting the distance between the front support 211 and the rear support 212; this allows the placement rack 21 to be suitable for placing hardware parts 8 of various sizes, and by adjusting the mounting position of the top rod 223 on the mounting rack 222, the waste removal device for hardware parts 8 can be made suitable for waste removal processing operations of hardware parts 8 of various sizes, making the equipment more versatile.

[0023] The frame 1 is equipped with a vibrator 26, which causes the waste material that has been removed to fall from the placement rack 21; that is, the vibrator 26 causes the placement rack 21 to vibrate, so that the waste material separated from the hardware 8 can fall from the placement rack 21 in time, thus avoiding affecting the equipment to continue to remove waste from the hardware 8.

[0024] The bending and picking device 3 includes a clamp 31 for holding the hardware part 8 and a torsion cylinder 32, wherein the clamp 31 is mounted on the torsion cylinder 32; The two clamps 31 of the two material handling devices 3 clamp the two hardware parts 8 that are connected together. The two torsion cylinders 32 drive the two clamps 31 to twist in opposite directions, so that the two hardware parts 8 are separated from the connecting parts 82. This realizes the rapid separation operation of the hardware parts 8 blanks, replaces manual operation, improves the processing efficiency of hardware parts 8, and effectively reduces production costs.

[0025] The material folding and picking device 3 is mounted on the frame 1 via a moving mechanism 5; the moving mechanism 5 includes a horizontally arranged horizontal moving cylinder 51, a vertically arranged vertical moving cylinder 52, and a circumferential rotating cylinder 53; The torsion cylinder 32 is mounted on the horizontal moving cylinder 51, and the horizontal moving cylinder 51 drives the torsion cylinder 32 to cause the clamp 31 to extend outward or retract inward. The horizontal moving cylinder 51 is mounted on the vertical moving cylinder 52, and the vertical moving cylinder 52 drives the clamp 31 to move up and down by driving the horizontal moving cylinder 51. The vertical moving cylinder 52 is mounted on the circumferential rotating cylinder 53, and the circumferential rotating cylinder 53 drives the clamp 31 to rotate circumferentially by driving the vertical moving cylinder 52. During the processing operation, the horizontal moving cylinder 51 first drives the clamps 31 to extend outward, and the two clamps 31 clamp the two main bodies of the hardware parts 8 on the hardware part 8 blank. Then, the two twisting cylinders 32 drive the two clamps 31 to twist in opposite directions to complete the separation of the hardware part 8 blank. Next, the horizontal moving cylinder 51 drives the clamps 31 to retract inward, so that the two clamps 31 holding the hardware parts 8 move back to back. Finally, the circumferential rotating cylinder 53 drives the clamps 31 to move backward. The device rotates to the top of the hopper of the hardware part 8; and under the drive of the vertical moving cylinder 52, the clamp 31 moves toward the hopper of the hardware part 8. The clamp 31 releases its grip on the hardware part 8, allowing the hardware part 8 to fall into the collection container, completing the part removal process. After completing the above actions, the horizontal moving cylinder 51 retracts inward, and then the vertical moving cylinder 52 extends upward, while the axial rotating cylinder rotates in the opposite direction, thus preparing for the next processing operation of the folding and part removal device 3.

[0026] The vertical moving cylinder 52 is equipped with a horizontally mounted slider 521, and the torsion cylinder 32 is equipped with a guide rail 321, which is adapted to the slider 521. Under the drive of the horizontal moving cylinder 51, the torsion cylinder 32 drives the clamp 31 to extend outward or retract inward, so that the torsion cylinder 32 can achieve the extension and retraction actions more smoothly under the drive of the horizontal moving cylinder 51.

[0027] The machine frame 1 is provided with a feeding conveyor belt 6 in front of it, and a feeding robot 7 is provided between the feeding conveyor belt 6 and the machine frame 1. The feeding robot 7 transfers the hardware parts 8 blanks on the feeding conveyor belt 6 to the placement rack 21 to achieve rapid feeding.
