The inside of the support block 3 is fixedly connected with a suction cup 4. A vacuum pump 5 is fixedly installed on the top of the bracket 1. An exhaust pipe A6 and an exhaust pipe B7 are fixedly installed at one end of the vacuum pump 5. The suction cup 4 and the exhaust pipe A6 are fixedly connected through a connecting pipe 8. A fixture box 9 is provided below the bracket 1. A sleeve 10 is fixedly connected to one side of the fixture box 9. The bottom of the sleeve 10 is fixedly connected through the connecting pipe 8. An adjusting piston 11 is slidably connected to the inside of the sleeve 10. One side of the adjusting piston 11 A piston rod 12 is fixedly connected, and a fixture 14 is installed inside the fixture box 9. One end of the piston rod 12 penetrates into the inside of the fixture box 9 and drives the opening and closing of the fixture 14 through a linkage mechanism. The top of the slide 2 is movably connected to a mounting plate 19, and a drive motor 20 is fixedly installed at the bottom of the mounting plate 19. A gear 21 is fixedly sleeved on the output end of the drive motor 20. Two sets of racks 22 that mesh with the gear 21 are provided on the top of the mounting plate 19. One end of the rack 22 is connected to a slider 23. A flip mechanism is provided at the bottom of the bracket 1. By starting the vacuum pump 5, the suction cup 4 is evacuated through the exhaust pipe A6 and the connecting pipe 8, and the extracted gas is discharged from the exhaust port, so that the inside and outside of the suction cup 4 A pressure difference is formed, so that the suction cup 4 can adsorb the workpiece under the action of the external atmospheric pressure, the adsorption effect is good, and the problem of scratching the surface of the product is avoided. In addition, by setting up multiple groups of suction cups 4, products and material heads in multiple cavities can be taken out at the same time during a removal process, which shortens the removal time and improves the injection molding efficiency. The adsorption capacity of the suction cup 4 can be controlled by adjusting the suction volume of the vacuum pump 5. While the suction cup 4 adsorbs the injection molded part, the inside of the sleeve 10 is evacuated by the vacuum pump 5. The vacuum pump 5 performs the evacuation operation and evacuates the inside of the sleeve 10 through the exhaust pipe B7. The suction force generated inside the sleeve 10 drives the adjusting piston 11 When the tool is moved to the left, the piston rod 12 drives the rotating seat 15 to move to the left, and the rotating seat 15 drives the connecting rod 17 to open, and the upper end of the clamp 14 is opened, so that the lower end of the clamp 14 is closed, thereby facilitating the clamping of the material head, thereby improving the stability of the suction fixture during the picking work. In addition, by starting the drive motor 20, the drive motor 20 drives the gear 21 to rotate, and the gear 21 drives the two sets of racks 22 to move toward each other, thereby driving the slider 23 to move through the rack 22, so that the slider 23 drives the slide 2 to move toward each other, and then the distance between the suction cups 4 can be adjusted according to actual conditions, so as to adapt to different usage needs and expand the scope of use of the suction fixture.
[0024] Specifically, a return spring 13 is sleeved on the outer surface of the piston rod 12, one end of the return spring 13 is fixedly connected to one side of the regulating piston 11, and the other end of the return spring 13 is fixedly connected to the inner wall of the sleeve 10. The return spring 13 is used to enable the piston rod 12 to return to its initial position quickly and accurately after completing one action, so as to facilitate the next action.
[0025] Specifically, the suction cup 4 is a corrugated vacuum suction cup, and the suction cup 4 is made of a transparent material. The corrugated structure enables the suction cup 4 to adapt to the irregularities of the workpiece surface to a certain extent, thereby achieving more stable adsorption.
[0026] Specifically, the linkage mechanism includes a rotating seat 15, which is fixedly connected to one end of the piston rod 12. Both ends of the rotating seat 15 are provided with a rotating shaft A16, and the two rotating shafts A16 are rotatably connected to a connecting rod 17. The other end of the connecting rod 17 is rotatably connected to the rotating shaft B18, and the rotating shaft B18 is fixedly set on the fixture box 9. One end of the fixture 14 is rotatably connected to the rotating shaft B18. When it is necessary to take out the product and the material head, the vacuum pump 5 is started and the vacuum pump 5 performs a vacuum operation. The inside of the sleeve 10 is evacuated through the vacuum pipe B7. The suction force generated inside the sleeve 10 drives the adjusting piston 11 to move to the left, and the piston rod 12 drives the rotating seat 15 to move to the left. The rotating seat 15 drives the connecting rod 17 to open, and the upper end of the clamp 14 is linked to open, so that the lower end of the clamp 14 is closed, thereby facilitating the clamping of the material head, thereby improving the stability of the suction fixture during work.
[0027] Specifically, a rubber sealing ring is fixedly sleeved on the outer surface of the regulating piston 11 . The main function of the rubber sealing ring is to provide a sealing effect to prevent gas leakage inside the sleeve 10 .
[0028] Specifically, the flipping mechanism includes a connecting plate 25, which is fixedly mounted on the bottom of the bracket 1, and a cylinder 26 is fixedly mounted below the connecting plate 25. The bottom of the connecting plate 25 is hinged with an L-shaped flipping plate 27, and the output end of the cylinder 26 is hinged with a connecting rod 28. The other end of the connecting rod 28 is hinged to the flipping plate 27, and the bottom of the flipping plate 27 is fixedly connected to the top of the fixture box 9. When the output end of the cylinder 26 is extended, the cylinder 26 transmits power to the flipping plate 27 through the connecting rod 28. The action of the output end of the cylinder 26 causes the connecting rod 28 to swing, and this swing is transmitted to the flipping plate 27, causing it to rotate around the hinge point. When the connecting rod 28 pushes the flipping plate 27, the flipping plate 27 rotates around the hinge point to realize the flipping action of the fixture box 9. The rotation of the flipping plate 27 enables the fixture box 9 to switch between vertical or horizontal positions to adapt to different pickup requirements.
[0029] Specifically, a slide groove 24 is provided on the top of the mounting plate 19, and the slider 23 is slidably connected to the inside of the slide groove 24. The bottom of the slider 23 is fixedly connected to the slide seat 2. By moving the slider 23 inside the slide groove 24, the distance between the suction cups 4 can be adjusted according to actual conditions to adapt to different usage needs.
[0030] Working principle: When in use, the vacuum pump 5 is started to evacuate the suction cup 4 through the exhaust pipe A6 and the connecting pipe 8, and the extracted gas is discharged from the exhaust port, so that a pressure difference is formed inside and outside the suction cup 4, so that the suction cup 4 can adsorb the workpiece under the action of the external atmospheric pressure, and the adsorption effect is good, and the problem of scratching the surface of the product is avoided. In addition, by setting up multiple groups of suction cups 4, products and material heads in multiple cavities can be taken out at the same time during a removal process, which shortens the removal time and improves the injection molding efficiency. The adsorption capacity of the suction cup 4 can be controlled by adjusting the suction volume of the vacuum pump 5. While the suction cup 4 adsorbs the injection molded part, the inside of the sleeve 10 is evacuated by the vacuum pump 5. The vacuum pump 5 performs the exhaust operation and evacuates the inside of the sleeve 10 through the exhaust pipe B7. The suction force generated inside the sleeve 10 drives the adjusting piston 11 to move to the left, and the piston rod 12 drives the rotating seat 15 to move to the left. The rotating seat 15 drives the connecting rod 17 to open, and the upper end of the clamp 14 is linked to open, so that The lower end of the clamp 14 is closed, which facilitates the clamping of the material head, thereby improving the stability of the suction fixture during the retrieval work. In addition, by starting the drive motor 20, the drive motor 20 drives the gear 21 to rotate, and the gear 21 drives the two sets of racks 22 to move toward each other, thereby driving the slider 23 to move through the rack 22, so that the slider 23 drives the slide 2 to move toward each other, and then the distance between the suction cups 4 can be adjusted according to actual conditions, thereby adapting to different usage needs and expanding the use range of the suction fixture. When the clamp 14 needs to be flipped, the cylinder 26 is started. When the output end of the cylinder 26 is extended, the cylinder 26 transmits power to the flip plate 27 through the connecting rod 28. The action of the output end of the cylinder 26 causes the connecting rod 28 to swing, and this swing is transmitted to the flip plate 27, causing it to rotate around the hinge point. When the connecting rod 28 pushes the flip plate 27, the flip plate 27 rotates around the hinge point to realize the flipping action of the clamp box 9. The rotation of the flip plate 27 enables the clamp box 9 to switch between vertical or horizontal positions to adapt to different retrieval requirements.
