Description

Technical Field

[0001] This utility model relates to the field of glass testing technology, specifically to an impact testing device for automotive glass film. Background Technology

[0002] Car window tinting involves applying a thin film to the front and rear windshields, side windows, and sunroof of a vehicle. This thin film is also called solar film or heat insulation film.

[0003] Publication number CN217237496U discloses a glass pressure resistance testing device. This device uses the movement of sliders one and two, combined with the fixing of clamps, to clamp glass of different sizes. The free movement of the support platform allows for corner support of glass of varying sizes, making the pressure resistance test more accurate and effectively preventing breakage during testing. However, this device requires waiting for the glass or glass film to be tested to be clamped and fixed before the pressure resistance test can be performed, which is time-consuming and has relatively low testing efficiency. Therefore, we propose an automotive glass film impact testing device. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an impact testing device for automotive glass films.

[0005] The technical solution adopted by this utility model to solve its technical problem is an automotive glass film impact testing device, including a testing base, a testing frame at the top of the testing base, a pressure electric telescopic rod at the center of the top of the testing frame, the extension end of the pressure electric telescopic rod being installed inside the pressure plate interface, the pressure plate interface being located at the center of the top of the pressure test plate, clamping mounting frames on both sides of the top of the pressure test plate, a clamping electric telescopic rod at the center of the top of the two clamping mounting frames, the extension end of the clamping electric telescopic rod being installed inside the clamping plate interface, and the clamping plate interface being opened at the top of the positioning clamping plate;

[0006] The surface of the testing base is provided with an installation groove in the center. A negative pressure pump is installed inside the installation groove. The air inlet at the top of the negative pressure pump is connected to the bottom center of the placement plate. The air outlet at the bottom of the negative pressure pump is connected to a connecting pipe. The bottom end of the connecting pipe is connected to the inside of the tank interface, and the tank interface is located at the top of the negative pressure tank.

[0007] By adopting the above technical solution, when the glass film is placed on the surface of the placement plate, the clamping electric telescopic rod at the top of the clamping mounting frame pushes the positioning clamping plate downward, so that the positioning clamping plate is flush with the pressure test plate. The buffer pad at the bottom of the positioning clamping plate first contacts the glass film to achieve the purpose of clamping and positioning. Then the pressure electric telescopic rod continues to extend downward, pushing the pressure test plate downward to perform pressure testing on the glass film. This reduces the number of operation steps for clamping the glass film with the clamping components, which improves work efficiency and reduces the time required for testing.

[0008] The glass film is placed on the surface of the placement plate, and then the negative pressure pump installed in the mounting slot is started. The air between the placement plate and the glass film is sucked out from the negative pressure exhaust port and introduced into the negative pressure tank through the connecting pipe, so that a negative pressure adsorption effect is formed between the placement plate and the glass film. Combined with the abutment and clamping of the positioning clamping plate, the glass film is positioned and clamped in a dual manner. There is no need to wait for the clamping components to move, which further improves the detection efficiency.

[0009] Specifically, the top surface of the placement plate has multiple negative pressure exhaust ports.

[0010] By adopting the above technical solution, a negative pressure pump is connected to the negative pressure extraction port to extract the air between the glass film and the placement plate when the glass film is placed on the placement plate, forming a negative pressure adsorption effect, which can be used in conjunction with the positioning clamping plate to fix the position of the glass film.

[0011] Specifically, brackets are fixedly installed on both sides of the bottom of the detection base.

[0012] By adopting the above technical solution, the testing base and its top connection structure are supported by a bracket.

[0013] Specifically, the top side surface of the testing base is provided with an operation panel for operating electrical equipment.

[0014] By adopting the above technical solution, the operation of electrical equipment in the device is controlled through the operation panel, thereby enabling continuous testing operations.

[0015] Specifically, the inner wall of the inspection frame is equipped with surface defect inspection lamps for illuminating colors that are sensitive to the naked eye.

[0016] By adopting the above technical solution, the glass film is illuminated by a surface defect detection lamp, and the quality problems of whether obvious cracks and breaks appear in the glass film after pressure testing are observed based on the principle of light refraction.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the glass film is placed on the surface of the placement plate, the clamping electric telescopic rod at the top of the clamping mounting bracket pushes the positioning clamping plate downward, making the positioning clamping plate flush with the pressure test plate. The buffer pad at the bottom of the positioning clamping plate first contacts the glass film to achieve the purpose of clamping and positioning. Then the pressure electric telescopic rod continues to extend downward, pushing the pressure test plate downward to perform pressure testing on the glass film. This reduces the number of operation steps for clamping the glass film with the clamping components, which improves work efficiency and reduces the time required for testing.

[0019] 2. Place the glass film on the surface of the placement plate, then start the negative pressure pump installed in the mounting slot. The air between the placement plate and the glass film is sucked out from the negative pressure extraction port and introduced into the negative pressure tank through the connecting pipe. This creates a negative pressure adsorption effect between the placement plate and the glass film. Combined with the abutment and clamping of the positioning clamping plate, the glass film is positioned and clamped in a dual manner. There is no need to wait for the clamping components to move, which further improves the detection efficiency. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3This utility model provides a technical solution: an automotive glass film impact testing device, including a testing base 1, a testing frame 2 at the top of the testing base 1, a pressure electric telescopic rod 3 at the center of the top of the testing frame 2, an extension end of the pressure electric telescopic rod 3 being installed inside a pressure plate interface 4, the pressure plate interface 4 being located at the center of the top of a pressure test plate 9, clamping mounting frames 5 being provided on both sides of the top of the pressure test plate 9, a clamping electric telescopic rod 6 being installed at the center of the top of the two clamping mounting frames 5, an extension end of the clamping electric telescopic rod 6 being installed inside a clamping plate interface 7, and the clamping plate interface 7 being opened at the top of a positioning clamping plate 8;

[0027] The surface of the detection base 1 is provided with a mounting groove 11 at the center. A negative pressure pump 12 is installed inside the mounting groove 11. The air inlet at the top of the negative pressure pump 12 is connected to the bottom center of the placement plate 13. The air outlet at the bottom of the negative pressure pump 12 is connected to a connecting pipe 15. The bottom end of the connecting pipe 15 is connected to the inside of the tank interface 16. The tank interface 16 is located at the top of the negative pressure tank 17.

[0028] In use, when the glass film is placed on the surface of the placement plate 13, the clamping electric telescopic rod 6 at the top of the clamping mounting bracket 5 pushes the positioning clamping plate 8 downward, so that the positioning clamping plate 8 is flush with the pressure test plate 9. The buffer pad at the bottom of the positioning clamping plate 8 first contacts the glass film to achieve the purpose of clamping and positioning. Then the pressure electric telescopic rod 3 continues to extend downward, pushing the pressure test plate 9 downward to perform pressure testing on the glass film. This reduces the number of operation steps for clamping the glass film with the clamping components, which improves work efficiency and reduces the time required for testing.

[0029] The glass film is placed on the surface of the placement plate 13, and then the negative pressure pump 12 installed in the mounting slot 11 is started to run. The air between the placement plate 13 and the glass film is sucked out from the negative pressure air extraction port 14 and input into the negative pressure tank 17 through the connecting pipe 15, so that a negative pressure adsorption effect is formed between the placement plate 13 and the glass film. Combined with the abutment and clamping of the positioning clamping plate 8, the glass film is positioned and clamped in a dual manner. There is no need to wait for the clamping components to move, which further improves the detection efficiency.

[0030] As shown in the figure, the top surface of the placement plate 13 has multiple negative pressure exhaust ports 14.

[0031] When in use, the air is drawn out by the negative pressure pump 12 through the negative pressure air extraction port 14 when the glass film is placed on the placement plate 13, forming a negative pressure adsorption effect, which can be used with the positioning clamping plate 8 to fix the position of the glass film.

[0032] As shown in the figure, brackets 10 are fixedly installed on both sides of the bottom end of the detection base 1.

[0033] During use, the detection base 1 and its top connection structure are supported by the bracket 10.

[0034] As shown in the figure, the top side surface of the detection base 1 is provided with an operation panel 18 for operating electrical equipment.

[0035] During use, the operation of the electrical equipment in the device is controlled through the operation panel 18 to carry out continuous testing operations.

[0036] As shown in the figure, the inner wall of the inspection frame 2 is provided with a surface defect inspection lamp 19 for irradiating colors that are sensitive to the naked eye.

[0037] When in use, the surface defect detection lamp 19 is used to illuminate the glass film, and the quality problems of obvious cracks and breaks are observed after the pressure test based on the principle of light refraction.

[0038] The working principle and usage process of this utility model are as follows: The glass film is placed on the surface of the placement plate 13. Then, the negative pressure pump 12 installed in the mounting slot 11 is started, drawing air from between the placement plate 13 and the glass film through the negative pressure extraction port 14. This air is then input into the negative pressure tank 17 through the connecting pipe 15, creating a negative pressure adsorption effect between the placement plate 13 and the glass film. Combined with the abutting clamping of the positioning clamping plate 8, this completes the dual positioning and clamping function of the glass film. The clamping electric telescopic rod 6 at the top of the clamping mounting frame 5 pushes the positioning clamping plate 8 downwards, thereby making the positioning clamping plate 8 flush with the pressure test plate 9. The glass film is first clamped and positioned by the buffer pad at the bottom of the positioning clamping plate 8. Then, the electric telescopic rod 3 continues to extend downward, pushing the pressure test plate 9 downward to perform a pressure test on the glass film. This reduces the number of operation steps for clamping the glass film, thereby improving work efficiency and reducing the time required for testing. The operation panel 18 controls the operation of the electrical equipment in the device to perform continuous testing. The surface defect detection lamp 19 is used to illuminate the glass film, and the glass film is observed for obvious cracks and breaks after the pressure test based on the principle of light refraction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
