[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Such as Figures 1 - 5As shown in the figure, a projection measurement device includes a bracket 1. At the bottom of the bracket 1, a measurement board 14 is fixedly arranged. The measurement board 14 is electrically connected to a display screen 15, and the display screen 15 is responsible for displaying the data detected by the measurement board 14. The device further includes a measurement mechanism for assisting in measuring the size of the anti-glare plate, a first mechanism for longitudinally adjusting the measurement mechanism, and a second mechanism for laterally adjusting the measurement mechanism. The first mechanism includes two groups of parallel slide bars 2 fixedly connected to the bracket 1. A slide sleeve 3 is slidably sleeved on each group of slide bars 2. The second mechanism includes two groups of mounting blocks 11. Each group of mounting blocks 11 is fixedly arranged with the corresponding slide sleeve 3. A longitudinal driving component cooperating with the slide bars 2 and a lateral driving component cooperating with the measurement mechanism are arranged on the two groups of mounting blocks 11. The longitudinal driving component drives the measurement mechanism to displace along the slide bars 2, and the lateral driving component drives the measurement mechanism to perform lateral displacement. The measurement mechanism includes a laser pen 10 cooperating with the measurement board 14. The measurement board 14 can detect the laser emitted by the laser pen 10 and calculate the light-receiving range and non-light-receiving range. When it is necessary to measure a certain measurement point of the anti-glare plate, the laser pen 10 can be moved to the same longitudinal section as the measurement point through the longitudinal driving component. After the laser pen 10 is turned on, the laser pen 10 is driven to pass horizontally above the measurement point through the lateral driving component. The measurement board 14 is responsible for monitoring the laser receiving area, calculating the shadow size, and transmitting the information to the display screen 15, so as to obtain the lateral size of the anti-glare plate at the measurement point without manual measurement, improving the measurement efficiency, accuracy, and reliability.

[0025] In some specific implementation schemes, in order to achieve the lateral displacement of the laser pen 10, the lateral driving component includes a lateral driving motor 16 fixedly connected to a group of mounting blocks 11. A lead screw 4 is fixedly connected to the output end of the lateral driving motor 16. A slide rail 5 is fixedly connected between the two groups of mounting blocks 11. The measurement mechanism includes a lead screw nut 6 threadedly connected to the lead screw 4. The lead screw 4 is used to drive the lead screw nut 6. A slider 7 slidably connected to the slide rail 5 is fixedly connected to the lead screw nut 6. The slider 7 is responsible for maintaining the stability of the laser pen 10 during the movement. A clamp 9 is arranged on one side of the slider 7, and the laser pen 10 is cooperatively arranged inside the clamp 9, which is convenient for disassembling and maintaining the laser pen 10. When the laser pen 10 needs to perform lateral displacement, the lateral driving motor 16 is started. The lateral driving motor 16 drives the lead screw 4 to rotate, and then drives the lead screw nut 6 to displace. The stability during the movement is ensured through the slider 7. The displacement of the slider 7 drives the displacement of the laser pen 10, realizing the lateral measurement of the laser pen 10.

[0026] In some specific embodiments, in order to facilitate the longitudinal fine-tuning of the laser pointer 10, an electric telescopic rod 8 is arranged between the slider 7 and the hoop 9; when the transverse drive motor 16 drives the laser pointer 10 to move horizontally and it is found that the laser pointer 10 fails to sweep to the measurement point, the extension length of the electric telescopic rod 8 can be adjusted, thereby driving the laser pointer 10 to move, so that the position of the laser pointer 10 corresponds to the measurement point, and thus the measurement of the measurement point is realized.

[0027] In some specific embodiments, in order to realize the longitudinal displacement of the laser pointer 10, the longitudinal drive assembly includes a longitudinal drive motor 12 fixedly connected to another set of mounting blocks 11. The output end of the longitudinal drive motor 12 is fixedly connected with a concave wheel 13, and a groove matching with the slide rod 2 is arranged on the side surface of the concave wheel 13; when the laser pointer 10 needs to move longitudinally, the longitudinal drive motor 12 is started, and the longitudinal drive motor 12 drives the concave wheel 13 to rotate. The concave wheel 13 rolls along the surface of the slide rod 2, and drives itself and the entire second mechanism to move longitudinally through the reaction force, thereby realizing the longitudinal displacement of the laser pointer 10.

[0028] In some specific embodiments, in order to improve the measurement efficiency of the measurement points on the anti-glare plate, multiple sets of measurement mechanisms and second mechanisms are arranged and longitudinally distributed on the first mechanism; the positions of each set of second mechanisms are adjusted so that each set of second mechanisms corresponds to a measurement point. During measurement, each set of laser pointers 10 can be driven to move horizontally and the measurement points on the anti-glare plate can be measured, thereby improving the measurement efficiency of the anti-glare plate.

[0029] In some specific embodiments, in order to reduce the friction between the sliding sleeve 3 and the slide rod 2, balls 17 are arranged inside the sliding sleeve 3, and the balls 17 are matched with the slide rod 2; when the sliding sleeve 3 moves along the slide rod 2, the balls 17 will roll along the slide rod 2 and support the sliding sleeve 3 at the same time. Static friction is generated between the balls 17 and the slide rod 2, thereby reducing the resistance generated during the movement of the sliding sleeve 3 and achieving the effect of reducing energy consumption.

[0030] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will be described below in combination with a specific application scenario:

[0031] When it is necessary to measure a certain measurement point of the anti-glare panel, start the longitudinal drive motor 12. The longitudinal drive motor 12 drives the concave wheel 13 to rotate. The concave wheel 13 rolls along the surface of the slide rod 2, and drives itself and the entire second mechanism to perform longitudinal displacement through the reaction force, thereby realizing the longitudinal displacement of the laser pointer 10, so that the laser pointer 10 moves to the same longitudinal section as the measurement point. Turn on the laser pointer 10, start the transverse drive motor 16. The transverse drive motor 16 drives the lead screw 4 to rotate, and then drives the lead screw nut 6 to displace, and ensures the stability during the movement through the slider 7. The displacement of the slider 7 drives the displacement of the laser pointer 10, realizing the transverse measurement of the laser pointer 10. When the transverse drive motor 16 drives the laser pointer 10 to displace transversely, it is found that the laser pointer 10 fails to sweep to the measurement point. The extension length of the electric telescopic rod 8 can be adjusted, thereby driving the displacement of the laser pointer 10, so that the position of the laser pointer 10 corresponds to the measurement point, thereby realizing the measurement of the measurement point. The measurement plate 14 is responsible for monitoring the laser receiving area, calculating the shadow size, and transmitting the information to the display screen 15, thereby obtaining the transverse size of the anti-glare panel at this measurement point, without manual measurement, improving the measurement efficiency, accuracy and reliability.

[0032] There are multiple groups of the second mechanisms. Adjust the positions of each group of the second mechanisms so that each group of the second mechanisms corresponds to a measurement point. During measurement, each group of laser pointers 10 can be driven to displace transversely and measure the measurement points on the anti-glare panel, thereby improving the measurement efficiency of the anti-glare panel. When the sliding sleeve 3 displaces along the slide rod 2, the ball 17 will roll along the slide rod 2 and support the sliding sleeve 3 at the same time. Static friction is generated between the ball 17 and the slide rod 2, thereby reducing the resistance generated by the sliding sleeve 3 during movement and achieving the effect of reducing energy consumption.

All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
