Description

Technical Field

[0001] This utility model relates to the field of automatic assembly technology, and in particular to a suction cup type robotic jig for automatically picking up and inserting parts. Background Technology

[0002] Injection molding machines are the main molding equipment used to mold thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molds. When removing injection-molded products, suction cups or sprue clamps are usually used for removal. Some products require inserts to be installed during assembly, which usually can only be done manually before further processing of the product. However, manually installing inserts and removing products increases the labor intensity of workers, and the production cycle is unstable, which has a significant impact on the product yield. In the patent application with application number 202422295002.X, a robotic jig for automatic product removal and automatic insert installation is disclosed. The jig guide post and the mold positioning hole make the insert horizontally aligned with the mold. The cylinder pushes the push plate and the ejector pin to install the insert onto the mold, which automatically completes the insert installation and greatly improves labor efficiency and the pass rate of inserts. However, there are the following defects: Since the insert must first be installed on the insert pin, the robotic arm cannot be rotated when the insert is pushed onto the mold by the ejector pin. Only in this way can the insert be prevented from falling off. Therefore, the robotic jig for automatic component assembly still needs improvement. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0024] The following is combined Figures 1 to 4 The specific embodiments of this utility model are described below.

[0025] Figure 1 This is a structural diagram of a suction cup-type robotic jig for automatically picking up and installing parts, provided by this utility model. Figure 2 This is a disassembly diagram of a suction cup-type robotic jig for automatically picking up and inserting parts, provided by this utility model. It shows that the jig includes a base plate 1, a push plate 2, a guide post 3, a ejector pin 6, an insert pin 7, a suction cup seat 8, a suction cup 110, and a cylinder 10. The base plate 1 and the push plate 2 are connected via the guide post 3. The ejector pin 6 is mounted on the push plate 2. The insert pin 7 passes through the ejector pin 6 and connects to the base plate 1. The suction cup seat 8 is also mounted on the push plate 2. The suction cup 110 is mounted on the suction cup seat 8. The cylinder 10 is mounted on the back of the base plate 1 and is connected to the suction cup seat 8 via an air passage.

[0026] The substrate 1 has guide post positioning holes 14, first cylinder shaft positioning holes 15, cylinder positioning holes 12, and insert pin positioning holes 13. Guide posts 3 are mounted in guide post positioning holes 14, and insert pins 7 are mounted in insert pin positioning holes 13. Cylinder 10 is fixed to the back of substrate 1 by bolts passing through cylinder positioning holes 12. Cylinder screw holes 103 corresponding to cylinder positioning holes 12 are also provided around cylinder 10. During installation, the bolts pass through cylinder positioning holes 12 and extend into cylinder screw holes 103 to achieve fixation. Cylinder 10 also has an air inlet 101 to provide gas for operation. The cylinder shaft 102 of cylinder 10 passes through the first cylinder shaft positioning hole 15. Furthermore, the substrate 1 also has robot arm positioning holes 11. Since the fixture needs to be grasped by a robot arm, robot arm positioning holes 11 are required for the robot arm to grasp it. The position and number of robot arm positioning holes 11 need to be adapted to the robot arm. For example, when the gripping structure of the robotic arm is a three-finger mechanical claw, there are 3 positioning holes 11 in the robotic arm, and their positions correspond to the positions of the adaptive fingers when the three-finger mechanical claw grips.

[0027] The push plate 2 has a ejector pin positioning hole 23, a second cylinder shaft positioning hole 22, and a guide sleeve positioning hole 21. The position and number of the ejector pin positioning holes 23 correspond to the insert pin positioning holes 13, the position of the second cylinder shaft positioning holes 22 corresponds to the first cylinder shaft positioning holes 15, and the position and number of the guide sleeve positioning holes 21 correspond to the guide post positioning holes 14. This ensures that the insert pin 7 can pass through the ejector pin 6 for installation, the guide sleeve 4 can pass through the guide post 3 for installation, and the cylinder shaft 102 can also pass through the second cylinder shaft positioning holes 22 and the first cylinder shaft positioning holes 15. The push plate 2 also has a suction cup seat positioning hole 24. The suction cup seat 8 is installed in the suction cup seat positioning hole 24, and the suction cup 110 is installed in the suction cup seat 8. The suction cup seat 8 has an air passage connection port. The cylinder 10 and the suction cup seat 8 are connected through the air passage, so that the cylinder 10 can drive the suction cup 110 on the suction cup seat 8 through the air passage.

[0028] The hollow ejector pin 6 is installed in the ejector pin positioning hole 23, and the insert pin 7 can pass through the ejector pin 6 for installation. The guide post 3 also passes through the guide sleeve positioning hole 21. The guide sleeve 4 is installed on the guide sleeve positioning hole 21, and the guide post 3 passes through the guide sleeve 4. The guide sleeve 4 can ensure the positioning accuracy of the long guide post 3. The cylinder shaft 102 of the cylinder 10 passes through the second cylinder shaft positioning hole 22, and there is a nut 5 on the second cylinder shaft positioning hole 22. The front end of the cylinder shaft 102 has an external thread that matches the internal thread of the nut 5. In this way, the cylinder shaft 102 can be screwed and fixed to the push plate 2 through the nut 5, so that the cylinder shaft 102 can drive the push plate 2 to move forward and backward together when it extends and retracts.

[0029] In addition, the front end of the setting pin 7 has a positioning hole 71 for the picking bead, and the picking bead 9 is installed in the positioning hole 71. The structure of the picking bead 9 is as follows: Figure 3 As shown. The pick-up bead 9 includes a fixing bead 91 and a spring 92. Normally, the fixing bead 91 is located inside the spring 92, with the top of the spring 92 higher than the top of the fixing bead 91. When the insert pin 7 moves forward with the fixture to pick up the insert 120 and needs to fix it, the insert 120 has a positioning hole or positioning groove that matches the fixing bead 91. At this time, the spring 92 is pressed down, and the fixing bead 91 is exposed. As the insert pin 7 advances, the fixing bead 91 enters the positioning hole or positioning groove, thus fixing the insert 120 and preventing it from falling off during the fixture's movement. When the fixing of the insert 120 is released, the spring springs up, lifting the insert 120 and disengaging the fixing bead 91 from the positioning hole or positioning groove, thus releasing the fixation. The specific number of pick-up beads 9 can be determined according to requirements.

[0030] After the fixing is removed, since the cylinder 10 is connected to the suction cup seat 8 and the ejector pin 6 through the air passage, in order to push the insert 120 into the fixed mold 130, the cylinder 10 drives the ejector pin 6 to push forward, thereby pushing the insert 120 into the fixed mold 130. In addition, since the cylinder shaft 102 is screwed to the push plate 2, the cylinder shaft 102 will also extend forward at this time, thereby pushing the push plate 2 forward to push out the insert 120. The fixed mold 130 can also be provided with a suction cup 110 to ensure that the insert 120 can be in place after being pushed out. The state when the fixture pushes the insert 120 into the fixed mold 130 is as follows. Figure 4 As shown.

[0031] To ensure the accurate positioning of the insert 120, guide pin alignment holes are required within the fixed mold 130. When the fixture is moved to the front of the fixed mold 130, the guide pin 3 needs to be aligned with the guide pin alignment hole and inserted to ensure accurate ejection of the insert 120, thus confirming the accurate positioning of the fixture. When using the fixture, the robotic arm first grasps the fixture and aligns the insert pin 7 with the pick-up point where the insert 120 is placed. The fixture is pushed towards the pick-up point, allowing the insert pin 7 to pick up the insert 120. Then, the pick-up bead 9 secures the insert 120 and moves the fixture to the fixed mold 130. The guide pin 3 is aligned with the guide pin alignment hole on the fixed mold 130 and inserted to ensure accurate docking between the fixture and the fixed mold 130. Subsequently, the ejector pin 6 and the push plate 2 are pushed forward under the drive of the cylinder 10, while the pick-up bead 9 releases the securing of the insert 120, pushing the insert 120 into the fixed mold 130, thus completing the placement of the insert 120. The robotic arm then rotates the fixture 180 degrees, aligning the suction cup 110 with the assembled product. Driven by the cylinder 10, the suction cup 110 picks up the assembled product, and the robotic arm moves the fixture holding the product to a suitable position before setting down the assembled product. Simultaneously, after the assembled product is removed, the next product awaiting assembly is pushed into the fixed mold 130, causing the insert 120 within the fixed mold 130 to be assembled onto the product awaiting assembly. After assembly, the assembled product is pulled out of the fixed mold 130 and positioned opposite it, allowing for the next cycle of insert 120 removal, product removal, and assembly.

[0032] This invention can efficiently transfer inserts to a fixed mold while ensuring their stability. The assembled product can then be promptly removed to prepare for the next assembly, thus enabling the product to stably and efficiently place and assemble inserts, thereby improving production efficiency.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
