Description

Technical Field

[0001] The invention belongs to the field of automotive airbag manufacturing, and particularly relates to a mechanical quick installation auxiliary gripper for an injection mold of an automotive airbag fabric. Background Art

[0002] In the current situation of the widespread and rapid development of the automotive industry, automotive safety has become the most concerned issue for people. Airbags play a crucial role. Due to the high production volume and large demand for the products involved in this case, it will pose a major test for an enterprise. Manual installation requires entering the mold area to install the airbag fabric, which has high risks, is not fixed, has non-standard visual inspection, and slow production efficiency. Summary of the Invention

[0003] The purpose of the invention is to solve the above deficiencies of the prior art and provide a mechanical quick installation auxiliary gripper for an injection mold of an automotive airbag fabric.

[0004] To achieve the above purpose, the following technical solutions are provided:

The second end and the third end are on a straight line, and both ends fix the cloth clamping mechanism. A cloth pushing and blowing mechanism is fixed between the second end and the third end;

[0007] The finger clamping mechanism includes a rectangular profile frame, and single finger clamps are installed on the outer sides of three sides of the profile frame;

[0008] The cloth clamping mechanism includes an air inlet cylinder, a cloth pulling cylinder fixed below the air inlet cylinder, a cloth clamping connecting plate fixed below the cloth pulling cylinder, and a cloth clamping cylinder fixed on the cloth clamping connecting plate. The end of the cloth clamping cylinder is provided with clamping claws, and the clamping claws include a first claw and a second claw. The airbag fabric is between the first claw and the second claw, and the left and right opening and closing realize clamping and loosening. The air inlet cylinder is fixed on the second end and the third end;

[0009] The cloth pushing and blowing mechanism includes a cloth pushing cylinder fixed on the gripper fixing plate between the second end and the third end, air nozzle fixing seats on both sides of the cloth pushing cylinder, air nozzle parts equally spaced on the air nozzle fixing seats, a cloth pushing connecting plate installed under the cloth pushing cylinder, spring rods installed at both ends of the cloth pushing connecting plate, and a push plate fixed at the lower part of the spring rods; the upper ends of the spring rods are installed on the cloth pushing connecting plate by means of double nut clamping, and the lower ends of the spring rods are fixed on the push plate by screws; the air nozzle parts include blowing nozzles and universal rods. One end of the universal rod is inserted into the air nozzle fixing seat, and the other end is connected to the blowing nozzle. Both rows of air nozzle parts are aligned with the push plate.

[0010] Preferably, the single-finger clip includes a rotating rod, a chuck, and a chuck rod. The chuck is installed on the chuck rod, the rotating rod is installed on the rotating rod through a swivel joint, the rotating rod is connected to the profile frame through an intermediate member, and one side of the chuck is provided with anti-slip rubber.

[0011] Preferably, it further includes a camera angle adjustment frame and a camera. The camera angle adjustment frame is fixed to the profile frame through a column, and the camera is fixed to the camera angle adjustment frame through bolts.

[0012] Preferably, a quick-release plug board is fixed on the gripper fixing plate for installing the manipulator.

[0013] The beneficial effects are as follows:

[0014] 1. The single-finger clip of the finger clip mechanism effectively grabs the airbag product from the mold, replacing the insecurity of manual handling by personnel.

[0015] 2. The cloth clamping mechanism is faster, smoother, and more stable in the installation position compared to manual handling of the mesh cloth by personnel. At the same time, it also avoids the danger during personnel participation and ensures personal safety.

[0016] 3. Since there are four positioning holes between the mold and the mesh cloth, and precise positioning is required for the four sides, it is inconvenient for personnel to position and align. The push cloth and blowing mechanism is used to fix the position of the grabbed mesh cloth and install the mesh cloth in a fixed position. The positioning points and the four sides can be installed more precisely and quickly into the mold, greatly improving production efficiency.

[0017] Generally speaking, it speeds up production efficiency, can meet the actual production requirements, is safe, stable, and has a high qualified rate. Compared with manual labor, it can greatly improve production efficiency. It can quickly position and install the airbag mesh cloth, solve the efficiency of the existing manual installation. The original manual installation production per shift (8 hours) was 150 pieces, and now the automated production per shift is 320 pieces. Moreover, after automation, the installation positions are consistent and the quality standards are unified. It can quickly and effectively identify unqualified products, and avoid the danger of personnel in the injection molding machine during manual production, effectively ensuring the safety of operators.
