[0002] According to incomplete statistics, the total number of disabled people in the country is about 85 million, of which about 20.54 million have hearing impairments. Due to the physical defects of hearing-impaired students themselves, it is difficult to communicate, cultivate, and integrate into society, resulting in problems such as low employment rate, poor job positions, unstable employment, and low salary treatment for deaf people. Therefore, it is urgent to improve the vocational and technical skills of hearing-impaired students and their ability to adapt to society to achieve high-quality employment.

[0003] The construction difficulty of the automobile beauty and decoration industry is relatively small, and the communication content with customers is less, which is a suitable employment direction for deaf people, especially the technology of pasting automobile solar films.

[0004] However, due to the characteristics of deaf people, their ability to control strength is very weak and they need to practice repeatedly. At the same time, when pasting solar films on the front windshield of automobiles, a heat gun is needed to bake the film so that the shape of the solar film fits the front windshield of the automobile as much as possible. Special attention needs to be paid to the temperature during the film baking process. If the temperature is too high, it will cause waste of the solar film. Therefore, an auxiliary tool is needed to enable hearing-impaired students to effectively control the temperature of the film baking during the film pasting process.

[0005] If real vehicles are used in teaching, the teaching cost will be greatly increased. Therefore, relevant teaching experimental benches and auxiliary tools are needed to reduce the teaching cost and improve the film pasting efficiency at the same time. Content of the Utility Model

Detailed Embodiments

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0020] The following describes the embodiments shown in the present utility model with reference to the accompanying drawings. Refer to Figure 1 , this embodiment includes: a bracket 1, a universal wheel 11 is provided at the lower end of the bracket 1 for facilitating the movement of the position, and an automotive front windshield 12 is fixedly provided at the upper end of the bracket 1. At the same time, in order to simulate the actual film pasting situation of the front windshield of a sedan, one side of the bracket 1 is higher than the other side, so that the automotive front windshield 12 is inclinedly installed, and the inclination angle is the same as that of the windshield of an actual vehicle. A trash can 13 and a storage rack 14 for placing a solar film 141 are also installed on one side of the bracket 1. Since it is necessary to make temporary adjustments during the film baking process, and at this time the muzzle of the heat gun 16 is in a high-temperature state, in order to prevent the high temperature of the muzzle from scalding people, a heat gun rack 15 is also provided at the upper part of the side surface of the bracket 1 for placing the heat gun 16.

[0021] Refer to Figure 2 and Figure 3 , several groups of direction marks 3 are adhered to the inner side (the side where the film does not need to be pasted) of the automotive front windshield 12. The direction marks 3 are a kind of flexible printed circuit made of polyester film or polyimide as the base material, which has high reliability and excellent flexibility. A number of parallel temperature-sensitive circuits are printed thereon. Each group of temperature-sensitive circuits is composed of a thermistor 31 and an LED lamp 32 connected in series. The resistance value of the thermistor 31 increases as the temperature rises. In this way, by adhering the direction marks 3 to the inner side of the windshield 12, hearing-impaired students can perform film baking according to the indicated direction of the direction marks 3. At the same time, the local temperature will rise due to the baking of the heat gun 16, the resistance value of the thermistor 31 will increase accordingly, and the brightness of the LED lamp 32 will gradually decrease. When the temperature reaches 450° (the limit temperature is 500 °C), the resistance value of the thermistor 31 will continue to increase, and the LED lamp 32 will go out or have a very low brightness, thus achieving the purpose of warning. Hearing-impaired students can bake the film within the safe temperature range by observing the brightness of the LED lamp 32, thereby avoiding poor film pasting effect caused by too high local temperature and wasting the solar film.

[0022] Refer to Figure 4, for the convenience of film application, the present utility model further includes a film application auxiliary frame 2, which includes two support rods 21 and two connecting rods 22. The support rods 21 have a certain curvature and are made of glass fiber reinforced plastic, with a certain toughness and can be moderately bent and deformed. The two support rods 21 are connected by two connecting rods 22 to form a frame. Clamping parts 23 are respectively arranged at both ends of the support rods 21 to clamp the solar film 141 during the film application process. A first tensioning rope 24 is also connected between the two connecting rods 22. For force balance, both ends of the first tensioning rope 24 are connected to the midpoints of the connecting rods 22. One end of a second tensioning rope 25 is connected to the midpoint of the first tensioning rope 24, and the other end of the second tensioning rope 25 is connected to the midpoint of the rotating rod 26. The rotating rod 26 is arranged above the support rods 21. By rotating the rotating rod 26 to drive the second tensioning rope 25 to rotate, the curvature of the support rods 21 can be adjusted. To fix the rotating rod 26, a buckle can also be arranged on the support rods 21. After adjusting the curvature of the support rods 21, the two ends of the rotating rod 26 can be snapped into the buckle.

[0023] During film application, first clean the front windshield 12 of the vehicle, then measure the size of the solar film 141. After tearing off the inner film of the solar film 141, use the clamping part 23 of the film application auxiliary frame 2 to tension the solar film 141, and then bring the film into contact with the front windshield 12 of the vehicle. Since the front windshield is usually a curved surface, only part of the solar film 141 is in contact with the front windshield at this time. Then the rotating rod 26 can be loosened, and the second tensioning rope 25 can be slowly loosened. The curvature of the support rods 21 gradually becomes smaller, so that the solar film 141 is in a relaxed state and slowly fits with the front windshield. At the same time, use a squeegee to squeeze out the bubbles in the solar film 141. After the preliminary fitting is completed, use a heat gun 16 to heat the film, and finally complete the fitting of the solar film 141.

[0024] During film application, first use a tape measure or a ruler to measure the length and width of the front windshield 12 of the vehicle, and roughly cut out the size of the solar film 141 for the front windshield 12 of the vehicle on the film cutting table according to the size; clean the outside of the front windshield 12 of the vehicle. After cleaning, draw an H-shaped water line on the outside of the glass, as Figure 5As shown, the rough-cut solar film 141 is fixed and tensioned by the clamping part 23 of the film pasting auxiliary frame 2, and then the solar film 141 is brought into contact with the automotive front windshield 12. Since the automotive front windshield 12 is usually curved, only part of the solar film 141 is in contact with the front windshield at this time. At this time, the rotating rod 26 can be released, and the second tensioning rope 25 is slowly released, and the radian of the support rod 21 gradually becomes smaller. Then the solar film 141 is in a relaxed state and slowly fits with the automotive front windshield 12. Since the automotive front windshield 12 is a curved surface, in order to make the solar film 141 fit completely with the curved surface, then a heat gun 16 is needed to bake the surface of the solar film 141. At this time, the baking of the film can be carried out according to the direction indicated by the direction mark 3, and at the same time, the temperature at this time can be judged according to the brightness of the LED lamp. After the film baking is completed, fine cutting is carried out according to the ceramic points around the automotive front windshield 12, and fine cutting is carried out along the second row or the third row of the ceramic points as required. After the fine cutting is completed, the solar film 141 is rolled up, and at the same time, a cleaning agent is sprayed on the rolled-up solar film 141. After completion, the solar film 141 is placed in the storage rack 14. Next, first tear off the direction mark 3 from the inside of the automotive front windshield 12, and then clean the inside of the automotive front windshield 12, and there should be no dust; after the cleaning of the inside of the automotive front windshield 12 is completed, film tearing is carried out. First, tear off a small corner, and then spray the cleaning liquid on the surface of the solar film 141 while tearing the film to prevent dust from entering the film. When the film tearing reaches the 1 / 3 position, film laying starts; after the film laying is completed, a soft squeegee is used to fix the solar film 141 and scrape out large air bubbles; a spray bottle is used to spray a cleaning agent on the surface of the solar film 141, the laminated paper after film tearing is laid flat on the solar film 141, and a hard squeegee is used to scrape off the moisture between the solar film 141 and the inside of the automotive front windshield 12, so that the solar film 141 fits completely with the inside of the automotive front windshield 12, and the hard squeegee is wrapped with masking tape for edge sealing, completing the film pasting training for the automotive front windshield 12.
