Description

Technical Field

[0001] This utility model relates to the field of automotive window tinting technology, specifically to an auxiliary positioning tool for automotive window tinting installation. Background Technology

[0002] Automotive window film, also known as heat insulation film or solar heat insulation film, is the most common name. "Heat insulation" refers to the effective blocking of infrared light. According to the authoritative definition of car2100, heat insulation film is generally a thin film made of PET substrate with water-soluble pressure-sensitive adhesive. It can adhere tightly to glass fragments, so that in the event of a collision or if the windshield is hit by a criminal, glass fragments will not fall off and fly.

[0003] When applying window film to a car, the film needs to be cut to a size larger than the car window glass to be covered. The traditional cutting method is to first measure the maximum size of the car window glass, then unfold the rolled-up car film on the worktable, press the unfolded car film down with a heavy object, then measure and mark the corresponding size on the car film with a ruler, and finally cut it. The cutting efficiency is low and needs to be improved. Utility Model Content

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1

[0028] Combined with appendix Figure 1-4 An auxiliary positioning tool for car film application includes a workbench 1, on one side of which a plurality of through holes 2 are evenly provided, and on the other side of which a U-shaped groove 3 for placing a car film roll is provided.

[0029] The bottom of the workbench 1 is provided with a cavity 5 with an opening 4 on one side and a through hole 2. A sealing plate 6 for sealing the through hole 2 is movably provided at the opening 4 of the cavity 5. A fan 7 for vacuum adsorption of automotive film is connected to the side of the cavity 5 away from the sealing plate 6.

[0030] The workbench 1 is provided with a slide groove 8 on one side, and a slider 9 is provided in the slide groove 8 with interference fit. The slider 9 is provided with a positioning and cutting device 10.

[0031] The workbench 1 is provided with scale lines 21.

[0032] The newly opened car film roll is placed in the U-shaped groove 3. The head of the car film is pulled out and passed through the bottom of the positioning and cutting device 10 and attached to the worktable 1. The blower 17 is turned on, and the blower 17 evacuates the cavity 5. The negative pressure generated by the cavity 5 adsorbs the car film onto the worktable 1. The scale lines on the worktable 1 can be seen through the car film. The positioning and cutting device 10 can mark the car film and cut it to the size required by people.

[0033] Example 2
