Description

Technical Field

[0001] This utility model relates to the field of automated injection molding equipment, and in particular to a three-dimensional automated part-removing fixture for automotive trim covers. Background Technology

[0002] In the injection molding production process, after the injection molded product is removed from the mold, it needs to be handled and the sprue needs to be separated. Traditional manual operation suffers from low efficiency, high labor frequency, slow transfer cycle, and poor product quality consistency, and is also prone to product damage due to human error. Existing robotic manual tooling has shortcomings in adapting to different specifications of injection molded products, gripping stability, and integration of sprue handling. For example, it is difficult to flexibly adjust the position of the gripping components to adapt to diverse products, and the structural design of the sprue clamp and suction cup working together is unreasonable, affecting production efficiency and product quality. Therefore, an automated tooling for injection molding products with an optimized structure is needed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a three-dimensional automated tooling for picking up automotive trim covers, which solves the problems in the background art.

[0004] Based on the above objectives, this utility model provides a three-dimensional automated part removal tooling for automotive trim covers, including a frame composed of crossbeams and longitudinal beams. One end of the frame is connected to a robotic arm, which drives the frame to rotate. Two suction cup mechanisms are provided in the middle of the frame away from the robotic arm, and sprue clamping mechanisms are provided on both sides of the frame away from the robotic arm. The suction cup mechanism includes a mounting arm set on the frame, a fixing rod extending through one side of the mounting arm, one end of the fixing rod being fixed to the mounting arm by a bolt assembly, and a sponge suction cup slidingly mounted on the other end of the fixing rod. The sponge suction cup can be reset after sliding outside the fixing rod. The sprue clamping mechanism includes a second mounting arm mounted on a frame, with a pneumatic gripper on one side of the second mounting arm.

[0005] Preferably, the end of the sponge suction cup near the mounting arm is a fixed block, and a return spring is sleeved on the outside of the fixed rod between the fixed block and the mounting arm.

[0006] Preferably, the sponge suction cups of the two suction cup mechanisms are connected by an air tube, and one of the sponge suction cups is connected to an air source through an air tube.

[0007] Preferably, the frame consists of aluminum profile crossbeams and longitudinal beams. Mounting arm one is slidably mounted on the bottom crossbeam of the frame on the side away from the fixing rod and mounting arm two is slidably mounted on the side away from the pneumatic gripper. Mounting arm one and mounting arm two are fixed to the bottom crossbeam of the frame by bolt assemblies.

[0008] Preferably, the sponge suction cup is equipped with a vacuum pressure sensor to detect the negative pressure value, and the pneumatic gripper is equipped with a pressure sensor to detect the clamping force.

[0009] Preferably, the pneumatic gripper includes a body mounted on the second mounting arm, a bidirectional water clamp cylinder mounted on the body, pistons mounted on both sides of the water clamp cylinder, one end of the gripper mounted on one side of the piston, the middle of the gripper being rotatably connected to the body, and the inner side of the other end of the gripper being serrated.

[0010] Preferably, a return spring is provided between the two grippers for connection.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a frame connected to a robotic arm to set up a suction cup mechanism and a sprue clamping mechanism to simultaneously separate the sprue nozzles during product adsorption and retrieval. The suction cup mechanism uses a sponge suction cup to adsorb the product. The sponge suction cup is connected to an air source through an air pipe to provide adsorption force. The sponge suction cup can slide on a fixed rod and is reset by a return spring. This increases the contact area and avoids hard friction when the sponge suction cup contacts the surface of the decorative cover, ensuring adsorption force and effectively protecting the product surface from scratches, thus improving the product qualification rate. The sprue clamping mechanism uses pneumatic grippers to achieve simultaneous sprue nozzle separation during retrieval. The pneumatic grippers are powered by a bidirectional water clamp cylinder in the main body. The water clamp cylinder moves through two pistons, driving the two grippers to rotate around the central connection point with the main body. The serrated part of the other end of the gripper clamps then grips and retrieves the product, achieving simultaneous sprue nozzle separation during retrieval without the need for additional equipment. The two grippers are reset by a return spring when the water clamp cylinder is released. The sponge suction cup uses a vacuum pressure sensor to detect the negative pressure value in order to adjust the suction force in real time; the pneumatic gripper is equipped with a pressure sensor to detect the clamping force in order to adjust the clamping force in real time. Both mounting arms one and two can slide on the frame to adjust their positions, thereby allowing for further adjustment of the positions of the suction cup mechanism and the sprue clamp mechanism according to actual conditions.

[0017] like Figures 1 to 4 As shown, a three-dimensional automated part-retrieving fixture for automotive trim covers includes a frame 1 composed of crossbeams and longitudinal beams.

Two suction cup mechanisms 2 are provided in the middle of the frame 1 away from the robotic arm, and sprue clamping mechanisms 3 are provided on both sides of the frame 1 away from the robotic arm. By setting the frame 1 connected to the robotic arm and setting the suction cup mechanisms 2 and sprue clamping mechanisms 3, the product can be adsorbed and the sprue can be separated synchronously during part-retrieving.

[0018] The suction cup mechanism 2 includes a mounting arm 4 mounted on a frame 1. A fixing rod 5 is inserted through one side of the mounting arm 4. One end of the fixing rod 5 is fixed to the mounting arm 4 by a bolt assembly. A sponge suction cup 6 is slidably mounted on the other end of the fixing rod 5. The sponge suction cup 6 can return to its original position after sliding outside the fixing rod 5. A fixing block 9 is located near the end of the sponge suction cup 6 on the mounting arm 4. A return spring 10 is mounted between the fixing block 9 and the mounting arm 4 outside the fixing rod 5. The sponge suction cups 6 of the suction cup mechanism 2 are connected to an air source through an air pipe. The suction cup mechanism 2 uses the sponge suction cups 6 to adsorb products. The sponge suction cups 6 provide adsorption force through the air source connected to the air pipe. The sponge suction cups 6 can slide on the fixing rod 5 and return to their original position through the return spring 10. In this way, when the sponge suction cups 6 come into contact with the surface of the decorative cover, the contact area can be increased and hard friction can be avoided. This ensures both adsorption force and effectively protects the product surface from scratches, thereby improving the product qualification rate.

[0019] The water inlet clamping mechanism 3 includes a mounting arm 2 7 mounted on the frame 1, with a pneumatic gripper 8 on one side of the mounting arm 2 7; the pneumatic gripper 8 includes a body 11 mounted on the mounting arm 2 7, a bidirectional water clamping cylinder 12 mounted on the body 11, pistons 13 on both sides of the water clamping cylinder 12, and one end of a gripper 14 on one side of the piston 13. The middle part of the gripper 14 is rotatably connected to the body 11, and the inner side of the other end of the gripper 14 is serrated; a return spring 2 15 is provided between the two grippers 14 for connection; water The mouth clamping mechanism 3 uses pneumatic grippers 8 to pick up parts and achieve synchronous separation of the sprue. The pneumatic grippers 8 are powered by the bidirectional water clamp cylinder 12 of the main body 11. The water clamp cylinder 12 moves through two pistons 13, which drives the two grippers 14 to rotate around the central part of the body 11. Thus, the serrated part of the other end of the gripper 14 clamps and picks up the parts, achieving synchronous separation of the sprue during part picking without the need for additional equipment. The two grippers 14 are reset by the second return spring 15 when the water clamp cylinder 12 is released.

Mounting arm 4 is slidably mounted on the bottom crossbeam of the frame 1 on the side away from the fixing rod 5 and mounting arm 7 is slidably mounted on the side away from the pneumatic gripper 8. Mounting arm 4 and mounting arm 7 are fixed to the bottom crossbeam of the frame 1 by bolt assemblies. Both mounting arm 4 and mounting arm 7 can slide and adjust their positions on the frame 1, thereby allowing for further adjustment of the positions of the suction cup mechanism 2 and the sprue clamp mechanism 3 according to actual conditions.

[0021] The sponge suction cup 6 is equipped with a vacuum pressure sensor to detect the negative pressure value, and the pneumatic gripper 8 is equipped with a pressure sensor to detect the clamping force. The sponge suction cup 6 uses the vacuum pressure sensor to detect the negative pressure value so as to adjust the suction force in real time; the pneumatic gripper 8 is equipped with a pressure sensor to detect the clamping force so as to adjust the clamping force in real time.
