Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automatic gripping fixture for metal clips on the sub-dashboard. Background Technology

[0002] The automotive sub-dashboard typically refers to components such as storage compartments, cup holders, or armrest boxes near the center console. During the manufacturing process of the automotive sub-dashboard, multiple metal clips are installed on the inside of the dashboard. These clips connect and secure the sub-dashboard to other interior components during vehicle installation. The metal clips provide stronger fixing force, facilitate assembly and maintenance, and, as a tight locking component, also prevent noise caused by vibrations while the vehicle is in motion.

[0003] With the advancement of automated production, robotic arms have now replaced manual labor in picking up clips from vibratory feeders and automatically installing them on the sub-dashboards. However, robotic arms can usually only pick up and install one clip at a time. Since each sub-dashboard has multiple clips to be installed, the frequent movement of the robotic arm between the vibratory feeder and the sub-dashboard reduces the installation efficiency of the clips on the sub-dashboards. Utility Model Content

[0004] In view of the above problems, this utility model provides an automatic gripping fixture for metal clips on the sub-dashboard.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic gripping fixture for a sub-dashboard metal buckle is provided, comprising a first manipulator and a second manipulator disposed on both sides of a workpiece fixture table and a vibratory feeder. The movable end of the first manipulator is provided with a first clamping fixture, and the movable end of the second manipulator is provided with a second clamping fixture.

[0007] The first clamping fixture includes a turntable, and the first robotic arm includes a first rotating arm with a rotatable movable end. The turntable is connected to the first rotating arm. A first connector for installing a first buckle is fixedly provided on the turntable. The first connector extends out of the turntable, and multiple first connectors are evenly spaced along the circumference of the turntable.

[0008] The second clamping fixture includes a first mounting frame, and the second robotic arm includes a second rotating arm with a rotatable movable end. The first mounting frame is connected to the second rotating arm. One end of the first mounting frame is provided with a plurality of second connectors for mounting the second buckle. The first mounting frame is provided with a driving component for driving the second connectors to slide along their own length direction. The other end of the first mounting frame is provided with a plurality of clamping cylinders for clamping the third buckle.

[0009] Furthermore, the driving component is a first cylinder, which is fixedly mounted on a first mounting bracket. The second connector is slidably mounted on the first mounting bracket along the length direction of the first mounting bracket, and the piston rod of the first cylinder is connected to the second connector.

[0010] Furthermore, multiple clamping cylinders are symmetrically arranged on both sides of the first mounting frame. Each clamping cylinder has two relatively movable gripping fingers, and the gripping fingers of the clamping cylinders arranged symmetrically on both sides of the first mounting frame are far apart from each other.

[0011] Furthermore, a plurality of second mounting brackets are slidably disposed on the first mounting bracket along the sliding direction of the second connector, and a clamping cylinder is fixedly disposed on the second mounting bracket. A plurality of second cylinders corresponding one-to-one with the second mounting brackets are fixedly disposed on the first mounting bracket, and the second cylinders are used to drive the second mounting brackets to slide.

[0012] Furthermore, the first connector is detachably connected to the turntable by bolts.

[0013] Furthermore, both the first connector and the second connector include a connecting rod and a replacement head. The replacement head is detachably connected to one end of the connecting rod by bolts. The replacement head is provided with connecting posts for insertion into the inner side of the first snap / second snap. Two connecting posts are spaced apart, and a connecting gap is formed between the two connecting posts for interference fit of the inner elastic buckle of the first snap / second snap.

[0014] The beneficial effects of this utility model are as follows: When installing metal clips on the sub-dashboard, the first and second robotic arms move the first and second clamping fixtures to the vibratory feeder. The first and second clamping fixtures connect and clamp the metal clips on the vibratory feeder. Both the first and second clamping fixtures can clamp multiple metal clips at once. Then, the robotic arms move the first and second clamping fixtures to the workpiece fixture table. The robotic arms then insert and install the metal clips on the first and second clamping fixtures one by one into the positions on the sub-dashboard where metal clips need to be installed, thereby improving the installation efficiency of metal clips on the sub-dashboard.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses an automatic gripping fixture for metal clips on a sub-instrument panel, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a first robotic arm 3 and a second robotic arm 4 located on both sides of the workpiece fixture 1 and the vibratory feeder 2. The workpiece fixture 1 is used for the installation and positioning of the sub-instrument panel. The vibratory feeder 2 has three parts, which respectively hold a first buckle 11, a second buckle 12 and a third buckle 13 of different shapes. The cross-section of the first buckle 11 and the second buckle 12 is U-shaped. The first buckle 11 and the second buckle 12 have outwardly protruding elastic protrusions and inwardly movable elastic buckles. The third buckle 13 is generally U-shaped. The third buckle 13 is positioned and installed on the sub-instrument panel by means of positioning plates with folded edges and other structures.

[0021] Both the first robotic arm 3 and the second robotic arm 4 are six-axis robotic arms. The movable end of the first robotic arm 3 is the first rotating arm 31, and the movable end of the second robotic arm 4 is the second rotating arm 41. Both the first robotic arm 3 and the second robotic arm 4 use servo motors to drive the rotation of their respective rotating arms and joints. A first gripping fixture 5 is hinged to the end of the first rotating arm 31, and the first gripping fixture 5 is rotated by a servo motor within the first rotating arm 31. A second gripping fixture 6 is hinged to the end of the second rotating arm 41, and the second gripping fixture 6 is rotated by a servo motor within the second rotating arm 41.

[0022] The first clamping fixture 5 includes a turntable 51, and the first robotic arm 3 includes a first rotating arm 31 with a rotatable movable end. The turntable 51 is connected to the first rotating arm 31. A first connector 52 for installing a first buckle 11 is fixedly provided on the turntable 51. The first connector 52 extends out of the turntable 51, and multiple first connectors 52 are evenly spaced along the circumference of the turntable 51. The first buckle 11 is picked up from the vibratory plate 2 and moved to the sub-instrument panel assembly by the first clamping fixture 5 through an interference fit with the first connector 52.

[0023] The second clamping fixture 6 includes a first mounting frame 61, which is hinged to the movable end of the second rotating arm 41. The second rotating arm 41 has a built-in servo drive motor that drives the first mounting frame 61 to rotate. One end of the first mounting frame 61 has a plurality of second connectors 62 neatly arranged for mounting the second buckles 12. The first mounting frame 61 is provided with a driving component that corresponds one-to-one with the plurality of second connectors 62 and drives each second connector 62 to slide along its own length. In this embodiment, the driving component can be a first cylinder 64, which is bolted to the first mounting frame 61. A guide frame is fixedly mounted on the first mounting frame 61. The second connectors 62 slide along the length of the first mounting frame 61 and pass through the guide frame. The guide frame activates the sliding guide action through the second connectors 62. The piston rod of the first cylinder 64 is connected to the second connector 62.

The second cylinders 66 can drive the clamping cylinders 63 that need to clamp / install the third clip 13 to move and protrude to one side of the first mounting bracket 61, making it easier to operate the third clip 13.

[0025] Furthermore, the first connector 52 is detachably connected to the turntable 51 by bolts. According to the processing requirements of the sub-instrument panel, an appropriate number of first connectors 52 can be installed on the turntable 51 so that the first clamping fixture 5 can pick up multiple first clips 11 that meet the installation requirements of the sub-instrument panel in one go.

[0026] In this embodiment, both the first connector 52 and the second connector 62 are composed of a connecting rod 71 and a replacement head 72. The replacement head 72 is detachably connected to one end of the connecting rod 71 by bolts. The end of the replacement head 72 away from the connecting rod 71 is integrally fixed with a connecting post for inserting into the inner side of the first buckle 11 / second buckle 12. Each replacement head 72 has two connecting posts spaced apart, and a connecting gap is formed between the two connecting posts for the inner elastic buckle of the first buckle 11 / second buckle 12 to be interference-fitted.
