Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to a fastener grabbing structure. Background Art

[0002] During the automobile assembly process, some parts need to be connected by inserting clips. For example, a car dashboard has multiple slots on the dashboard shell. The clips are inserted into the slots, and then the dashboard is assembled with other parts of the car body through the clips.

[0003] Currently, the insertion step of the buckle is generally completed manually, which has high labor costs and low production efficiency. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a fastener grasping structure, which replaces manual operation through the mutual cooperation of a mechanical arm and a plurality of clamping parts, saves labor costs and improves work efficiency.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A fastener grasping structure comprises a rotating plate mounted on a mechanical arm, wherein the mechanical arm can drive the rotating plate to rotate, and the rotating plate is provided with a plurality of clamping parts which can be clamped into the back of the buckle.

[0007] Working principle: The mechanical arm drives the clamping part to be inserted into the buckle. There is a protrusion on the back of the buckle. Since the buckle itself is elastic, the protrusion is clamped on the clamping part. Then the buckle is inserted into the slot of the instrument panel housing through the mechanical arm. At this time, the front of the buckle is squeezed, and the friction force on the front is greater than the friction force on the protrusion. After the mechanical arm controls the clamping part to be pulled out, the buckle remains in the slot.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. The rotating plate and the clamping part are driven to move by the mechanical arm, so that the clamping part is clamped into the back of the buckle, and then the rotating plate, the clamping part and the buckle are moved to the vicinity of the instrument panel housing by the mechanical arm, and the buckle is inserted into the instrument panel housing, which replaces manual operation and saves labor costs.

[0010] 2. By setting up multiple clamping parts, the robotic arm can control the clamping parts to clamp multiple buckles at a time, then move to the vicinity of the instrument panel housing, and then insert them one by one. Compared with clamping and inserting a single buckle, the work efficiency is improved.

[0011] As a preferred embodiment of the present utility model, the clamping portion includes a first clamping rod, one end of the first clamping rod is fixedly connected to the rotating plate, and the other end of the first clamping rod is provided with a clamping block.

[0012] Beneficial effect: The back of some buckles is V-shaped. By setting a clamping block to be inserted into the back of the buckle, the buckle itself has elasticity, so that the first clamping rod can pass through the clamping block to clamp this type of buckle.

[0013] As a preferred embodiment of the present invention, both sides of the clamping block are provided with limiting grooves, and both sides of the first clamping rod are provided with stepped grooves.

[0014] Beneficial effect: By setting the limiting groove, it is easier for the buckle protruding part to fit, and the protruding part can be limited. The stepped groove allows the first clamping rod to be inserted deeper into the buckle.

[0015] As a preferred embodiment of the present utility model, the clamping portion includes a second clamping rod, one end of the second clamping rod is fixedly connected to the rotating plate, and the other end of the second clamping rod is provided with a through groove.

[0016] Beneficial effect: For a buckle with a protrusion on the back, this type of buckle can be clamped by providing a through groove to engage with the protrusion.

[0017] As a preferred embodiment of the present invention, grooves are provided on both sides of the through slot.

[0018] Beneficial effect: The groove makes it easier for the buckle raised part to fit, and the raised part can be limited.

[0019] As a preferred embodiment of the present utility model, the robotic arm is a six-axis robotic arm.

[0020] Beneficial effects: The six-axis robotic arm has a high degree of freedom and flexibility. When the dashboard housing is on the tooling, the opening directions of the card slot are different. The six-axis robotic arm can drive the clamped buckle to insert the buckle at different angles to achieve automatic insertion and replace manual operation.

[0021] As a preferred embodiment of the present invention, the rotating plate is detachably connected to the end drive shaft of the six-axis robot arm.

[0022] Beneficial effect: By providing a detachable rotating plate, rotating plates and clamping parts of different specifications can be replaced to adapt to workpieces to be processed of different specifications.

[0023] As a preferred embodiment of the present invention, the number of the clamping parts is greater than or equal to the number of buckles into which the instrument panel is clamped.

[0024] Beneficial effect: The robot arm can clamp the same number of clips on the rotating plate, and then move all the clamped clips to the vicinity of the instrument panel housing and insert them one by one. During the clamping process, a new instrument panel to be processed can be replaced synchronously, thereby improving the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
