Description

Technical Field

[0001] This utility model relates to the field of automotive membrane testing technology, specifically to an automotive membrane puncture resistance testing device. Background Technology

[0002] Automotive window film is a thin film applied to the front and rear windshields, side windows, and sunroof of a vehicle. This film, also known as solar film or heat insulation film, primarily blocks ultraviolet rays, reduces heat, prevents injuries from flying glass, and reduces glare. Additionally, its one-way visibility helps protect personal privacy.

[0003] Patent No. 202323350885.1 discloses an automotive film puncture resistance testing device. This device improves the safety of operation by allowing the fixing platform to be moved out from under the puncture needle for fixing when fixing the automotive film to be tested, thus preventing the problem of the puncture needle easily causing accidental injury to the staff when fixing the automotive film.

[0004] However, existing automotive film puncture resistance testing devices rely on a second motor and a second lead screw to drive the fixed platform to move laterally back and forth. After the automotive film on the fixed platform is tested, the second motor and the second lead screw are needed to move the fixed platform to the end of the testing platform, remove the automotive film from the test structure, and then place the automotive film to be tested back onto the fixed platform for fixation. The second motor and the second lead screw are then used again to move the fixing sleeve under the puncture needle for testing. The operation is cumbersome and labor-intensive, which affects the testing efficiency of automotive films. Therefore, an automotive film puncture resistance testing device is proposed. Utility Model Content

[0005] To address the problems in the background art, this utility model provides an automotive membrane puncture resistance testing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an automotive film puncture resistance testing device, including an operating table. A fixed frame is welded to one side of the operating table. A cylinder is bolted inside the fixed frame. A drive frame is bolted to the power output end of the cylinder. A puncture needle for testing the automotive film is symmetrically fixed to the inside of the drive frame with screws. A servo motor for providing power is bolted inside the operating table. A support rod is keyed to the power output end of the servo motor. A gear is splined to the outside of the support rod. A gear plate A is meshed with the gear. A placement frame A for placing the automotive film is welded to the top of the gear plate A. A gear plate B is meshed with the side of the gear away from the gear plate A. A placement frame B for placing the automotive film is welded to the top of the gear plate B. An electric telescopic rod is screwed to the top of both placement frames A and B. A support plate is screwed to the end of the electric telescopic rod. A limiting plate for limiting the position of the automotive film is symmetrically welded to the outside of the support plate.

[0007] By adopting the above technical solution, the car film is first placed on the placement frame A. Then, the electric telescopic rod inside the placement frame A drives the support plate to move. Then, the support plate drives the externally symmetrically welded limiting plates to clamp and fix the car film on both sides. Then, the servo motor inside the operating table drives the support rod to rotate clockwise. Then, the gear outside the support rod meshes with the external toothed plate A and toothed plate B, so that toothed plate A drives the placement frame A to move, and toothed plate B drives the placement frame B to move. The placement frame A moves to the bottom of the drive frame. Then, the placement frame B moves to the end of the operating table. Then, the cylinder inside the fixed frame drives the drive frame to move, so that the puncture needle inside the drive frame contacts the car film on the placement frame A to perform a puncture test on the car film. When placement rack A moves to the bottom of the drive frame for puncture testing, placement rack B moves to the end of the operating table. The automotive film to be tested is then placed on placement rack B and secured. After the puncture test on the automotive film on placement rack A is completed, the servo motor inside the operating table drives the support rod to rotate counterclockwise. The gears outside the support rod mesh with gear plate A and gear plate B. Gear plate A then moves placement rack A, and gear plate B moves placement rack B, causing placement rack B to move to the bottom of the drive frame. Place rack A moves to the end of the operating table, and the puncture needle on the drive frame is used to perform the puncture test on the automotive film on placement rack B. Simultaneously, the automotive film from placement rack A, after the puncture test, is removed, thereby improving the efficiency of the automotive film puncture test.

[0008] Specifically, the inner side of the limiting plate is screwed with a rubber block that increases the friction force on the automotive film.

[0009] By adopting the above technical solution, when the limiting plate comes into contact with the car film, the rubber block inside the limiting plate increases the friction on the surface of the car film, thereby improving the stability of the car film fixation.

[0010] Specifically, both toothed plate A and toothed plate B are welded with sliding sleeves on the outside, and sliding rods are symmetrically welded inside the operating table.

[0011] By adopting the above technical solution, when toothed plate A and toothed plate B move, the sliding sleeves welded to the outside of toothed plate A and toothed plate B slide outside the sliding rods symmetrically welded inside the operating table, thereby improving the stability of the movement of toothed plate A and toothed plate B.

[0012] Specifically, the fixed frame has symmetrically formed limiting grooves on its surface, and the drive frame has symmetrically welded limiting blocks that slide within the limiting grooves on its inner side.

[0013] By adopting the above technical solution, when the drive frame moves, the symmetrically welded limiting blocks on the drive frame slide within the symmetrically opened limiting grooves on the surface of the fixed frame, thereby improving the stability of the drive frame movement.

[0014] Specifically, the input terminals of the electric telescopic rod, cylinder, and servo motor are all electrically connected to the power supply terminal of an external power source.

[0015] By adopting the above technical solution, the electrical equipment can operate normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0016] The beneficial effects of this utility model are: The present invention discloses an automotive film puncture resistance testing device. When the placement rack A moves to the bottom of the drive rack for puncture testing, the placement rack B moves to the end of the operating table. The automotive film to be tested is then placed on the placement rack B and fixed. After the puncture test of the automotive film on the placement rack A is completed, the servo motor inside the operating table drives the support rod to rotate counterclockwise. The gear outside the support rod meshes with the toothed plate A and the toothed plate B. Then, the toothed plate A drives the placement rack A to move, and the toothed plate B drives the placement rack B to move, so that the placement rack B moves to the bottom of the drive rack, and the placement rack A moves to the end of the operating table. The puncture needle on the drive rack is used to perform puncture testing on the automotive film on the placement rack B. At the same time, the automotive film that has completed the puncture test on the placement rack A is removed, thereby improving the efficiency of automotive film puncture testing.

Detailed Implementation

[0020] 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.

[0021] To improve the efficiency of puncture testing for automotive films, as one embodiment of this utility model, such as... Figures 1 to 4 As shown, the automotive film puncture resistance testing device of this utility model includes an operating table 6. A fixing frame 1 is welded to one side of the operating table 6. A cylinder 20 is bolted inside the fixing frame 1. A drive frame 4 is bolted to the power output end of the cylinder 20. A puncture needle 5 for testing the automotive film is symmetrically fixed to the inner side of the drive frame 4 with screws. A servo motor 15 for providing power is bolted inside the operating table 6. A support rod 14 is keyed to the power output end of the servo motor 15. The support rod 14 is externally splined... There is a gear 13, which is externally meshed with a toothed plate A16. A placement rack A7 for placing car film is welded to the top of the toothed plate A16. A toothed plate B17 is meshed with the side of the gear 13 away from the toothed plate A16. A placement rack B8 for placing car film is welded to the top of the toothed plate B17. An electric telescopic rod 12 is screwed to the top of both the placement rack A7 and the placement rack B8. A support plate 11 is screwed to the end of the electric telescopic rod 12. A limiting plate 9 for limiting the position of the car film is symmetrically welded to the outside of the support plate 11.

[0022] In use, the car film is first placed on the placement frame A7. Then, the electric telescopic rod 12 inside the placement frame A7 drives the support plate 11 to move. Then, the support plate 11 drives the externally symmetrically welded limiting plate 9 to clamp and fix the two sides of the car film. Then, the servo motor 15 inside the operating table 6 drives the support rod 14 to rotate clockwise. Then, the gear 13 outside the support rod 14 meshes with the external toothed plate A16 and toothed plate B17, so that the toothed plate A16 drives the placement frame A7 to move, and the toothed plate B17 drives the placement frame B8 to move. The placement frame A7 moves to the bottom of the drive frame 4. Then, the placement frame B8 moves to the end of the operating table 6. Then, the cylinder 20 inside the fixing frame 1 drives the drive frame 4 to move, so that the puncture needle 5 inside the drive frame 4 contacts the car film on the placement frame A7 to perform a puncture test on the car film. When the placement rack A7 moves to the underside of the drive rack 4 for puncture testing, the placement rack B8 moves to the end of the operating table 6. The automotive film to be tested is then placed on the placement rack B8 and fixed. After the puncture test of the automotive film on the placement rack A7 is completed, the servo motor 15 inside the operating table 6 drives the support rod 14 to rotate counterclockwise. The gear 13 outside the support rod 14 meshes with the toothed plate A16 and the toothed plate B17. Then, the toothed plate A16 drives the placement rack A7 to move, and the toothed plate B17 drives the placement rack B8 to move, so that the placement rack B8 moves to the underside of the drive rack 4 and the placement rack A7 moves to the end of the operating table 6. The puncture needle 5 on the drive rack 4 is used to perform the puncture test on the automotive film on the placement rack B8. At the same time, the automotive film that has completed the puncture test on the placement rack A7 is removed, thereby improving the efficiency of the automotive film puncture test.

[0023] To improve the stability of automotive film fixation, for example, such as Figure 3 As shown, the present invention also includes a rubber block 10 for increasing the friction force on the automotive film, which is fixed to the inner side of the limiting plate 9 by screws.

[0024] When in use, when the limiting plate 9 comes into contact with the car film, the rubber block 10 inside the limiting plate 9 increases the friction on the surface of the car film, thereby improving the stability of the car film fixation.

[0025] To improve the stability of the movement of toothed plates A16 and B17, for example, such as Figure 2 As shown, the present invention also includes that the toothed plate A16 and toothed plate B17 are both welded with sliding sleeves 18 on the outside, and that the operating table 6 is symmetrically welded with sliding rods 19 inside.

[0026] When in use, as toothed plates A16 and B17 move, the sliding sleeves 18 welded to the outside of toothed plates A16 and B17 slide outside the sliding rods 19 symmetrically welded inside the operating table 6, thereby improving the stability of the movement of toothed plates A16 and B17.

[0027] To improve the stability of the movement of the drive frame 4, for example, such as Figure 1 As shown, the present invention also includes, on the surface of the fixed frame 1, symmetrically formed limiting grooves 2, and on the inner side of the drive frame 4, symmetrically welded limiting blocks 3 that slide within the limiting grooves 2.

[0028] When in use, as the drive frame 4 moves, the symmetrically welded limiting blocks 3 on the drive frame 4 slide within the symmetrically opened limiting grooves 2 on the surface of the fixed frame 1, thereby improving the stability of the drive frame 4's movement.

[0029] For electrical equipment to function properly, for example, such as Figures 2 to 4 As shown, this utility model also includes the electric telescopic rod 12, the cylinder 20 and the input terminal of the servo motor 15, all of which are electrically connected to the power supply terminal of an external power source.

[0030] When in use, the electrical equipment works normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0031] In use, the car film is first placed on the placement rack A7. Then, the electric telescopic rod 12 inside the placement rack A7 is driven by the PLC controller to move the support plate 11. The support plate 11 then drives the externally symmetrically welded limiting plates 9 to clamp and fix the car film on both sides. The rubber blocks 10 inside the limiting plates 9 increase the friction on the surface of the car film. Then, the servo motor 15 inside the operating table 6 is driven by the PLC controller to rotate the support rod 14 clockwise. The support rod 14 is installed in the bearing seat of the operating table 6 through a deep groove ball bearing. The bearing seat is welded to the inner wall of the operating table 6. Subsequently, the gear 13 outside the support rod 14 meshes with the external gear plates A16 and B17. The sliding sleeves 18 welded to the outside of the gear plates A16 and B17 slide outside the sliding rods 19 symmetrically welded inside the operating table 6, improving the stability of the movement of the gear plates A16 and B17. The gear plate A16 drives the placement frame A7 to move, and the gear plate B17 drives the placement frame B8 to move. The placement frame A7 moves to below the drive frame 4, and then the placement frame B8 moves to the end of the operating table 6. Then, the cylinder 20 inside the fixed frame 1 drives the drive frame 4 to move, so that the puncture needle 5 inside the drive frame 4 and the placement... The automotive film on rack A7 is brought into contact with the film for a puncture test. The film is then placed on rack B8, whose internal structure is identical to that of rack A7, thus securing the film. After the puncture test on rack A7, cylinder 20 in rack 1 drives drive frame 4 vertically upwards, separating the puncture needle 5 from the film on rack A7. Subsequently, servo motor 15 in operating table 6, controlled by the PLC controller, drives support rod 14 to rotate counterclockwise. Gear 13 outside the drive frame 4 meshes with gear plate A16 and gear plate B17. Then gear plate A16 drives the placement frame A7 to move, and gear plate B17 drives the placement frame B8 to move, so that the placement frame B8 moves below the drive frame 4 and the placement frame A7 moves to the end of the operating table 6. Then, the cylinder 20 in the fixed frame 1 is driven by the PLC controller to drive the drive frame 4 vertically downward, so that the puncture needle 5 in the drive frame 4 performs puncture test on the car film on the placement frame B8. At the same time, the car film that has completed the puncture test on the placement frame A7 is removed, thereby improving the puncture test efficiency of the car film.
