Description

Technical Field

[0001] This utility model relates to the field of injection molding robot technology, and more specifically, to an injection molding robot part removal fixture. Background Technology

[0002] Injection molding robots are machines specifically designed for automating injection molding production. They reduce heavy manual labor, improve working conditions and safety, and mimic some functions of the human upper limbs. These robots can be automatically controlled to transport products or manipulate tools according to predetermined requirements. The end of the injection molding robot is equipped with a jig for picking up the molded parts. However, due to the varying sizes of injection molded parts, large jigs are inconvenient for picking up small parts, while small jigs are inconvenient for picking up large parts. Using jigs of various sizes increases costs. Furthermore, after prolonged contact with the injection molded parts, the suction cups gradually accumulate impurities, which can affect the use of the suction cups. Therefore, we propose a part-picking jig for injection molding robots. Utility Model Content

[0010] The advantages of this utility model are: (1) In this utility model, the distance between the suction cups at both ends of the main square tube is adjusted by sliding the two main adjustment seats in the main square tube, and the main square tube and the two main adjustment seats are fixed by the cooperation of the first through hole, the first fixing hole, the first nut and the first bolt.

[0011] (2) In this utility model, the jig is moved by a robotic arm. Before the bottom of the suction cup comes into contact with the injection molded part, the gas is introduced into the second vacuum generator by an external air compressor. The gas discharged from the outlet of the second vacuum generator is discharged from the exhaust pipe and the blowing nozzle. The gas blown out by the blowing nozzle is used to clean the suction cup part to be adsorbed. At the same time, the suction end of the second vacuum generator draws air into the inner cavity of the collection box. The negative pressure in the inner cavity of the collection box causes the suction pipe and the suction pipe to generate suction. The suction of the suction pipe draws the impurities blown down by the blowing nozzle into the cloth bag in the inner cavity of the collection box and collects them. This realizes the function of cleaning the suction cup part to be adsorbed and avoids the impurities from affecting the suction cup. Attached Figure Description

[0024] It should be noted that this utility model is a part-retrieving fixture for an injection molding robot. In use, the fixture is first connected to the end of the robot via bolts, connecting sleeve 16, and connecting hole 17. Then, the two main adjusting seats 2 are pulled to move within the main square tube 1, thereby adjusting the distance between the suction cups 6 on both sides of the main square tube 1. After adjustment, the first bolt 11 is inserted into the inner cavity of the first fixing hole 9 and the first through hole 8, and the bottom thread of the first bolt 11 is threaded onto the first nut 10 to fix the main square tube 1 and the main adjusting seat 2. Next, the two auxiliary adjusting seats 4 at both ends of the two auxiliary square tubes 3 are pulled to adjust the distance between the suction cups 6 at both ends of the auxiliary square tubes 3. After adjustment, the second bolt 15 is inserted into the inner cavity of the second through hole 12 and the second fixing hole 13, and the bottom thread of the second bolt 15 is threaded onto the second nut 14 to fix the auxiliary square tube 3 and the auxiliary adjusting seat 4, thereby fixing the four suction cups 6. The distance between them is adjusted to accommodate injection molded parts of different sizes. Then, a robotic arm moves the fixture. Before the bottom of the suction cup 6 contacts the injection molded part, an external air compressor introduces gas into the second vacuum generator 21. The gas discharged from the outlet of the second vacuum generator 21 is discharged through the exhaust pipe 22 and the blowing nozzle 23. The gas blown out by the blowing nozzle 23 sweeps the area to be suctioned by the suction cup 6. At the same time, the suction end of the second vacuum generator 21 draws air into the inner cavity of the collection box 18. The negative pressure in the inner cavity of the collection box 18 causes the suction pipe 26 and the impurity suction pipe 27 to generate suction. The suction of the impurity suction pipe 27 sucks the impurities blown down by the blowing nozzle 23 into the cloth bag 30 in the inner cavity of the collection box 18 for collection. Finally, when the end of the suction cup 6 contacts the injection molded part, the air compressor introduces gas into the first vacuum generator 19. At this time, the suction end of the first vacuum generator 19 draws air through the suction pipe 20 and the suction cup 6, thereby using the negative pressure inside the suction cup 6 to pick up the injection molded part.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
