Description

Technical Field

[0001] The utility model relates to an automatic bending and friction testing device for coated airbag fabric, belonging to the field of airbag processing. Background Technique

[0002] In the existing airbag processing industry, the quality inspection of coated airbag fabric is a crucial link. However, traditional inspection methods mainly rely on manual operation, which not only has low efficiency but also is difficult to ensure the consistency and accuracy of inspection. Especially when conducting bending and friction tests on coated airbag fabric, manual operation is prone to introducing human errors, and the test process is complex and cumbersome, making it difficult to meet the requirements of large-scale and automated inspection.

[0003] Specifically, traditional bending and friction tests usually require operators to manually place the sample on the test bench, then perform bending and friction operations on the sample manually or mechanically, and finally the inspection unit conducts the inspection. This method not only takes a long time and has a high labor intensity, but also the test results are easily affected by the experience and technical level of the operators, resulting in instability and non-repeatability of the test results.

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please refer to Figure 1 , Figure 2 , the present utility model provides a technical solution for an automatic test bending friction device for a coated airbag cloth, including:

[0027] Sampling component 1 is used to send sample G to the sample feeding component 2; in one embodiment, the sampling component 1 adopts an existing multi-axis manipulator to transfer the sample G to be measured to the working area A of the sample feeding component 2.

[0028] Sample feeding component 2 includes several chucks 22 with telescopic members 23. The chucks 22 clamp and send sample G into the testing component 3; in one embodiment, there are 3 chucks 22, which are installed on a turntable 21. The 3 chucks 22 are circumferentially arrayed, so the angle between each chuck 22 is 120°; thus, the turntable 21 rotates 120° each time to switch the chuck 22 (the turntable 21 is driven by a servo motor, and the servo motor is not shown in the figure) to different positions.

[0029] Furthermore, the chuck 22 is actuated by a cylinder to clamp the sample.

[0030] Furthermore, the telescopic member 23 is a cylinder, and the telescopic member 23 drives the chuck 22 to perform telescopic movement.

[0031] Testing component 3, the testing component 3 includes means for clamping sample G; the telescopic member 23 drives sample G to move to bend the sample; in one embodiment, the testing component 3 includes a pressure foot 31, a displaceable base 32, and a pressure foot rod 33 for reducing the distance between the pressure foot 31 and the base 32; the pressure foot 31 is fixed on the pressure foot rod 33; the pressure foot 31 and the base 32 are located on the upper and lower sides of sample G and clamp sample G, wherein the widths of the pressure foot 31 and the base 32 are both smaller than that of sample G.

[0032] Preferably, the base 32 is displaced by an electric slide rail 34.

[0033] Preferably, one end of the pressure foot rod 33 away from the pressure foot 31 is hinged on the cabinet 5, and the pressure foot rod 33 is driven to rotate by a servo motor (not shown in the figure).

[0034] Inspection unit 4 is used to inspect sample G after passing through the testing component 3. The inspection unit 4 includes an existing vision inspection system to take pictures of sample G after being tested by the testing component 3 and inspect the number of meshes.

[0035] Furthermore, the sampling component 1, the sample feeding component 2 (telescopic member 23, servo motor driving the turntable 21, cylinder), the testing component 3 (servo motor driving the pressure foot rod 33, electric slide rail 34), and the inspection unit 4 are all controlled by a controller 6. The connection between the controller and the above electrical components can complete the actions through simple programming by those skilled in the art and corresponding circuit wiring. And these electrical components can be purchased directly in the market, so the model structure and circuit diagram are not described in detail in this specification.

[0036] Working principle: Step 1; The sampling component 1 transports the sample G to be measured to the working area A of the sample feeding component 2, and this working area A is at a position where the chuck 22 can clamp it.

[0037] Step 2; The turntable 21 rotates, driving the chuck 22 holding the sample G to be measured to rotate clockwise (refer to the Figure 1 direction) by 120°, so that the chuck 22 corresponds to the test component 3.

[0038] Step 3; During Step 2, the base 32 moves backward through the electric slide rail 34 to reserve space for the movement of the chuck 22. After the chuck 22 rotates clockwise by 120°, the base 32 resets, and then the pressure foot rod 33 drives the pressure foot 31 to press down, and the pressure foot 31 and the base 32 clamp the sample G.

[0039] Step 4; Based on Step 3, after the sample G is clamped and fixed, the telescopic member 23 drives the chuck 22 to perform reciprocating telescopic motion to bend the sample G.

[0040] Step 5; Reset the pressure foot 31, and the chuck 22 continues to rotate clockwise by 120° so that the tested sample G corresponds to the inspection unit 4, and the inspection unit 4 takes a photo to inspect the mesh number.

[0041] Step 6; The chuck 22 continues to rotate clockwise by 120° to make the chuck 22 return to the working area A in Step 1. During the rotation, the chuck 22 releases the sample G, and the sample G falls into the collection area B.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
