Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a gripper fixture that prevents the separation of the inner and outer panels of a car door. Background Technology

[0002] To prevent the separation of the assembled inner and outer door panels, traditional methods use suction cups and clamps for fixation. However, for the upper window frame of the door, which is prone to detachment, there are no effective solutions due to the limitations of part shape and the structure of subsequent molds. The upper window frame of the door is extremely prone to separation of the inner and outer panels after assembly, and due to product design limitations, it is difficult to place suction cups in this location using traditional fixtures. Utility Model Content

[0003] This invention addresses the problem of assembled inner and outer panels easily separating during robot gripping. It proposes a gripper fixture to prevent separation of the inner and outer panels of a car door. This fixture is mounted on a robot at the assembly station of the inner and outer panel assembly and can place the assembled inner and outer panel assembly into the lower cavity of the edge-sealing mold, effectively reducing the risk of poor edge-sealing due to panel separation. The specific technical solution is as follows: A gripper fixture for preventing the separation of inner and outer door panels is mounted on a robot at the assembly station of inner and outer door panels. It includes a main positioning pin and a secondary positioning pin, the positions of which correspond to the main and secondary positioning holes on the inner door panel. Two assembly support blocks are provided on both sides of the fixture to support the assembly of the inner and outer door panels. Four outer panel suction cups are arranged in the middle of the fixture. Three inner panel clamping blocks are arranged at the corresponding positions on the inner panels. An outer panel window frame clamping block is arranged at the outer panel window frame position.

[0004] Furthermore, the outer panel window frame clamping block includes a motion control air pipe, which is connected to the clamp via a clamp pivot. The clamp is tweezer-shaped, and a telescopic probe is positioned parallel to the clamp. A positioning sensor is located above the telescopic probe, and the positioning sensor is electrically connected to the clamp via a robot controller. During use, when the clamp contacts the door panel, the telescopic probe retracts into the sensing area of ​​the positioning sensor, the sensor light illuminates, and the clamp performs the clamping action on the sheet metal.

[0005] Furthermore, the support block of the main assembly block is made of nylon.

[0006] Furthermore, the outer panel suction cup is a vacuum suction cup with an air cut-off and pressure-maintaining function to avoid the safety risk of parts falling off the gripper fixture.

[0007] Furthermore, the telescopic probe is configured as a telescopic spring, and a nylon contact block is provided at the outer end of the spring.

[0008] This utility model's gripper offers several advantages: it employs a vacuum suction cup, preventing parts from falling due to air leakage and locking; it features a "tweezers"-shaped outer panel window frame clamping block, overcoming the limitations of traditional clamping mechanisms that require opening space, allowing parts to be fully fed to the bottom of the mold before opening, eliminating the need for pre-release, making it suitable for clamping window frames on car doors; it also includes two nylon-made splicing lifting blocks to prevent scratches and damage upon contact with the outer panel. This utility model effectively solves the problem of easily detaching spliced ​​inner and outer panels during robot gripping, reducing the risk of poor edge binding due to panel detachment.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 1 As shown, a gripper fixture for preventing the separation of the inner and outer panels of a car door is mounted on a robot at the assembly station of the inner and outer panels of the car door. It includes a main positioning pin 1 and a secondary positioning pin 9, the positions of which correspond to the main and secondary positioning holes of the inner panel of the car door. Two assembly blocks (assembly block a 2 and assembly block b 8) are set on both sides of the fixture to support the assembly of the inner and outer door panels. Four outer panel suction cups 3 are arranged in the middle of the fixture. Three inner panel clamping blocks (inner panel clamping block a 4, inner panel clamping block b 6, and inner panel clamping block c 7) are arranged at the corresponding inner panel positions of the fixture. An outer panel window frame clamping block 5 is arranged at the outer panel window frame position.

[0013] The outer panel window frame clamping block 5 includes a motion control air pipe 51, which is connected to a clamp 54 via a clamp pivot 55. The clamp is tweezer-shaped, and a telescopic probe 53 is positioned parallel to the clamp. A position sensor 52 is located above the telescopic probe 53, and the position sensor 52 is electrically connected to the clamp 54 via a robot controller. During use, when the clamp contacts the door panel, the telescopic probe 53 retracts into the sensing area of ​​the position sensor 52, the sensor light illuminates, and the motion control air pipe 51 activates the clamp 54 to perform the clamping action on the sheet metal.

[0014] The support block of the main assembly block is made of nylon. The outer plate suction cup 3 is a vacuum suction cup with air cut-off and pressure maintenance function to avoid the safety risk of parts falling off the gripper. The telescopic probe 53 is configured as a telescopic spring, and a nylon contact block is provided on the outer end of the spring.

[0015] This utility model uses a vacuum suction cup to lock and prevent parts from falling out due to air leakage; it is equipped with a "tweezers" shaped outer panel window frame clamping block, which overcomes the limitation of traditional clamping mechanisms that require opening space. The parts can be completely sent to the bottom of the mold before opening, without the need to loosen them in advance. It is suitable for clamping and securing window frames on car doors; at the same time, it is equipped with two splicing support blocks. These support blocks are made of nylon material to avoid scratches and external damage after contact with the outer panel.

[0016] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
