Description

Technical Field

[0001] The utility model relates to the field of injection molding, and particularly relates to a manipulator jig for automatically picking products by a suction cup and automatically installing inserts. Background Art

[0002] An injection molding machine is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies; when taking out injection molded products, suction cups are usually used for adsorption and removal, or sprue clips are used for removal. However, due to the need to install inserts during the molding of some products, usually only manual installation of inserts can be used during molding. However, manual picking of products and installing inserts increases the labor intensity of workers, the production cycle is unstable, and it has a great impact on the yield rate of products. In the patent application with the application number 202421021788.X, a manipulator jig for automatically picking products and automatically installing inserts is disclosed. The insert is horizontally aligned with the mold through the jig guide post and the mold positioning hole, and the cylinder pushes the push plate and the thimble needle to push the insert onto the mold insert pin, automatically completing the installation of the insert, which greatly improves the labor efficiency and the qualified rate of the insert. However, there are the following defects: First, since the product is picked up in parallel, it can only be taken out unilaterally and on the same side as the installation screw. When there is interference with the position of the positioning screw of the fixture, it cannot be installed and used; Second, the parallel clamping method is convenient for small products and not applicable when the product size is large; Third, the product is prone to being scratched, so the manipulator jig for automatically installing inserts still needs to be improved. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides a manipulator jig for automatically picking products by a suction cup and automatically installing inserts. After the mold is opened, the manipulator descends, and the insert is horizontally aligned with the mold through the jig guide post and the mold positioning hole. The cylinder pushes the push plate and the thimble needle to push the insert onto the mold insert pin. When sucking the product, the posture of the manipulator in the mold is flipped, and the product is adsorbed by multiple suction cups to complete the operation of automatically sucking the product.

[0004] To achieve the above object, the technical solution of the present invention is: A manipulator jig for automatically picking products by a suction cup and automatically installing inserts, including a base plate, a push plate, guide posts, guide sleeves, nuts, thimble needles, insert pins, and a cylinder. The cylinder is arranged on the base plate, and the four guide posts are arranged on the base plate, outside the cylinder shaft. The four guide sleeves are respectively arranged at the four corners of the push plate, and the positions of the four guide sleeves and the four guide posts correspond one by one. The thimble needle is arranged outside the push plate, and the insert pin is arranged inside the thimble needle. It also includes a suction cup seat, suction cups, and an auxiliary base plate. The auxiliary base plate is arranged at the bottom of the base plate and forms an L shape with the base plate. The suction cup seat is arranged on the base plate, and the suction cups are arranged on the suction cup seat.

[0005] Preferably, the model of the suction cup holder is M12-11H-L87T, the model of the suction cup is ST-20S3, and the suction cup and the suction cup holder are connected by snap-fit.

[0006] The technical effects of the utility model are as follows: all the mounting screws are on the fixed mold side, and the product is taken out from the movable mold side without position interference; the number of suction cups can be adjusted at will according to the size of the product, and it is also convenient to suck up large products; the suction cup type product removal avoids the risk of bumping and scratching.

DETAILED DESCRIPTION

[0013] like Figures 1 to 4 As shown, a suction cup type robot fixture for automatically taking out products and automatically installing inserts includes a base plate 1, a push plate 2, a guide column 3, a guide sleeve 4, a nut 5, a sleeve needle 6, an insert needle 7, a suction cup seat 8, a suction cup 9, a cylinder 10 and an auxiliary base plate 11.

[0014] The manipulator positioning holes 1-1, four guide pillar positioning holes 1-2, one cylinder positioning hole 1-3, four ejector pin positioning holes Ⅰ 1-4 and one cylinder shaft positioning hole Ⅰ 1-5 are respectively arranged at different positions on the substrate 1; four guide sleeve positioning holes 2-2, four ejector pin positioning holes Ⅱ 2-4 and one cylinder shaft positioning hole Ⅱ 2-5 are respectively arranged at different positions on the push plate 2; the positions of the four guide pillar positioning holes 1-2 and the four guide sleeve positioning holes 2-2 correspond; the positions of the ejector pin positioning holes Ⅰ 1-4 and the ejector pin positioning holes Ⅱ 2-4 correspond and are located at the four corners of the push plate 2; the positions of the cylinder shaft positioning hole Ⅰ 1-5 and the cylinder shaft positioning hole Ⅱ 2-5 correspond.

[0015] The cylinder body 10-3 is fixedly screwed on the substrate 1 through the cylinder positioning hole 1-3;

[0016] The cylinder shaft 10-2 sequentially passes through the cylinder shaft positioning hole Ⅰ 1-5 on the substrate 1 and the cylinder shaft positioning hole Ⅱ 2-5 on the push plate 2 and is fixedly screwed with a nut 5; one end of each of the four guide pillars 3 passes through the guide pillar mounting holes 1-2 on the substrate 1 and is fixed on the substrate 1, and the four guide sleeves 4 are respectively installed in the four guide sleeve positioning holes 2-2;

[0017] The number and positions of the ejector pins 6 are set according to the shape of the product 13. In this embodiment, the product has four inserts. The four ejector pins 6 pass through the ejector pin positioning holes Ⅱ 2-4 on the push plate 2 and are installed in the ejector pin positioning holes Ⅰ 1-4, and insert pins 7 are installed in each ejector pin 6;

[0018] The auxiliary substrate 11 is screwed and installed on the bottom of the substrate 1 through the auxiliary substrate mounting holes 11-1. The substrate 1 and the auxiliary substrate 11 form an L-shaped structure. According to the size of the product, an appropriate number of suction cup seats 8 of model M12-11H-L87T are screwed and installed on the auxiliary substrate 11, and suction cups 9 of model ST-20S3 are snap-fitted on each suction cup seat 8.

[0019] A manipulator jig for sucking products automatically and loading inserts automatically: operate according to the following steps:

[0020] 1. Fix the substrate 1 on the robotic arm through the manipulator positioning hole 1-1, and the suction cup seat air inlet 8-1 and the cylinder air inlet 10-1 of the cylinder 10 are respectively connected to the air circuit of the robotic arm.

[0021] Second, when installing the insert, the manipulator automatically picks up the insert 12 outside the mold 14, the main arm rises and horizontally enters the standby position and returns to the standby position. After the mold 14 is opened, the manipulator descends to move the jig into the space between the fixed side and the moving side of the mold. The four guide posts 3 are aligned with the positioning holes of the mold 14. The main arm of the manipulator moves, the air inlet 10-1 of the ejector cylinder is inflated, and the cylinder 10 applies air pressure to push the ejector plate 2 and the thimble 6 to push the insert 12 into the mold 14 to complete the insert installation. When picking up the product 13, the manipulator moves the jig to a position without interference with the mold, flips the jig in the space between the moving side and the fixed side of the mold so that the center of the suction cup 9 is aligned with the center of the product 13. The vacuum generator at the air inlet 8-1 of the suction cup seat applies negative pressure to the air holes in the suction cup seat 8 to the suction cup 9 to adsorb the product 13 on the suction cup 9. The manipulator retreats and rises, the jig horizontally exits the mold and descends to release the product. After the jig automatically picks up the insert 12, it returns to the standby position to complete an insert cycle.
