Description

Technical Field

[0001] This invention relates to an automatic sample feeding and testing device for vacuum adsorption and temperature control of automotive environmental protection films, belonging to the technical field of testing equipment. Background Technology

[0002] Modern cars extensively use environmentally friendly films or tapes, such as butyl tape, sound insulation and sound absorption films, expanding films, and reinforcing films. The purpose is to enhance the strength, sealing, and shock absorption of the car body. Not only are they required to be environmentally friendly, but they also need to ensure that the films or tapes do not fall off or deform when the car enters the phosphating production line after the film or tape application process.

[0003] To ensure that the applied films or tapes do not fall off or deform, existing auto parts factories use handheld test samples to conduct multi-point penetration tests on semi-finished and finished products during production using a penetration tester. After the test, the average value is used to obtain the data to determine whether the semi-finished and finished products are qualified.

[0004] When holding the test piece by hand, pressing it down with the hand to insert it into the needle penetration meter for multiple multi-point tests can cause slight movements of the sample due to human factors, such as prolonged testing time, breathing, and hand tremors. In particular, during the shifting process of testing multiple points, the test points may become inaccurate, resulting in inaccurate test data and a low test success rate. Secondly, holding the test sample into the needle penetration meter by hand can easily cause the standard needle of the needle penetration meter to touch the hand, resulting in a work injury. Summary of the Invention

[0005] To reduce the instability of manually handling test specimens, ensure that the needle penetration does not pierce the hand, and mitigate the impact of seasonal temperature differences on test results, this application provides a vacuum adsorption temperature-controlled automatic sample feeding test device for automotive environmental protection films. This invention enables the X-axis and Y-axis traveling mechanisms to move crosswise and automatically feed the sample, completing multi-point testing of the test specimen. It also features a temperature-controlled vacuum adsorption worktable, allowing the test specimen adsorbed on the vacuum suction cup to undergo a reliability test of its needle penetration using a standard needle.

[0006] The technical solution adopted in this invention is: an automatic sample feeding and testing device for vacuum adsorption and temperature control of automotive environmental protection film, including a needle penetration meter, a frame, an air compressor, a vacuum generator, a temperature controller, a vacuum adsorption heating stage, a connecting plate, an X-axis traveling mechanism, a programmable servo controller, and a Y-axis traveling mechanism; the Y-axis traveling mechanism and the needle penetration meter are respectively fixed on the frame, the X-axis traveling mechanism is fixed on the Y-axis traveling mechanism, and the connecting plate is fixed on the X-axis traveling mechanism. One side of the connecting plate is placed on the needle penetration meter stage and has a clearance fit with the needle penetration meter stage. A vacuum adsorption heating stage is fixed on the connecting plate; the air compressor is connected to the adsorption tube connector of the vacuum adsorption plate bottom plate of the vacuum adsorption heating stage through a vacuum generator; the temperature controller is connected to the thermal sensor and the heating element of the vacuum adsorption heating stage; the programmable servo controller is connected to the Y-axis stepper motor and the X-axis stepper motor; the cooperation of the X-axis walking mechanism and the Y-axis walking mechanism can drive the vacuum adsorption heating stage on the connecting plate to move back and forth and left and right between the needle penetration tester platform and the standard needle; the vacuum adsorption heating stage is used for the adsorption and temperature control of the test sample.

[0007] The technical advantages of this invention are as follows: This invention uses a programmable servo controller (PLC) to control the cross movement of the X-axis and Y-axis walking mechanisms, which drives the test sample adsorbed by the vacuum adsorption heating stage on the connecting plate. It automatically delivers the sample to the six test points A, B, C, D, E, and F and performs the test, which improves the test accuracy and achieves a test success rate of over 95%. It also ensures that the test sample will not injure the hand during the test.

[0008] The temperature controller can heat at the set temperature, unaffected by the external temperature, and automatically controls the heating temperature of the heating element of the vacuum adsorption heating table, realizing the standardized operation of the test sample; the structural design of the vacuum adsorption plate base plate and the vacuum adsorption plate can firmly adsorb the test sample on the vacuum adsorption plate, ensuring the test accuracy of the test sample; the structural design of the venting valve can complete the replacement of the test sample.
