[0006] Therefore, a new scheme is needed to solve this problem. SUMMARY

[0007] In view of the deficiencies of the prior art, the purpose of the present application is to provide a vertical flat screen making machine and its control process.

[0022] By adopting the technical scheme, the laser and the recognition lens are connected to the bearing plate, so that the laser and the recognition lens can move synchronously, the scanning recognition and the laser processing are highly synchronized, and the precision of the laser is ensured.

[0023] The recognition lens is fixedly connected to the bearing plate, is used for recognizing and scanning the specifications of the screen plate fixed to the clamping mechanism, and performs distance measurement and focusing.

[0024] The laser is horizontally and slidably connected to the bearing plate through a displacement seat, and the displacement seat is connected to the recognition lens data through a microcontroller, so as to adjust the distance between the laser and the screen plate according to the distance measurement and focusing state.

[0027] Placing, the screen is vertically placed on the fixed horizontal support, the bottom end of the screen is embedded into the fixed horizontal support, and the displacement moving clamping support is moved until it touches the top end of the clamped screen;

[0028] Resetting initially, the reciprocating mechanism is displaced to the initial station along the length direction of the machine body, and drives the bearing plate to be displaced to the lowest point of the reciprocating mechanism;

[0029] Primary scanning, when driving the reciprocating mechanism to be displaced from one side to the other side of the machine body, the recognition lens is driven to scan the screen clamped on the clamping mechanism from bottom to top and from top to bottom in turn;

By measuring the distance of the screen to the horizontal distance sensor, and by comparing and calculating the data between multiple horizontal distance sensors, the verticality of the screen placement can be determined, thereby realizing the fine-tuning control of the laser. At the same time, multiple horizontal distance sensors are set along the length of the fixed horizontal support. The number of horizontal distance sensors that respond to changes in distance measurement can be used to determine the length of the screen in the length direction.

[0040] By adopting the above technical solution, a vertical distance sensor is also set up. When the moving clamping support moves back and forth along the guide rail, the vertical distance sensor determines the distance between the moving clamping support and the fixed horizontal support. This information is then transmitted to the reciprocating mechanism via the microprocessor to control the displacement range of the bearing plate. This improves the applicability and adaptability of the equipment and provides more efficient screen making for screens of different specifications.

[0041] In summary, the present invention has the following beneficial effects:

[0042] The clamping mechanism vertically holds the screen to one side of the machine body, keeping it upright. This solves the problem of large screens requiring a large area when laser-making large screens. Furthermore, the vertical orientation of the screen, due to its own weight, extends along its planar direction, avoiding the slight deformation that can occur in the middle or on the surface of a horizontally placed screen, which affects laser precision. During laser screen-making, a recognition module scans and identifies the screen's veins and mesh, improving accuracy. Simultaneously, the recognition module and reciprocating mechanism enable high-precision screen-making processing.

[0043] Horizontal distance sensor and vertical distance sensor are arranged, when the moving clamping support moves along the guide rail, the vertical distance sensor is arranged to judge the distance between the moving clamping support and the fixed horizontal support, so that the microprocessor transmits the displacement interval of the bearing plate to the reciprocating mechanism, thereby improving the applicability and adaptability of the equipment, and the screen making efficiency is higher for different specifications of the screen.

[0067] Embodiment two, the control process of the vertical flat screen making machine, the control process comprises:

[0068] The screen is placed vertically on the fixed horizontal support frame 21, the bottom end of the screen is embedded on the fixed horizontal support frame 21, and the displacement moving clamping support frame 22 is moved until it touches the top end of the clamped screen. Specifically, when the screen is placed on the fixed horizontal support frame 21, the distance between the screen and the distance sensor 23 is monitored through the distance sensors 23 arranged at equal intervals on the fixed horizontal support frame 21, to determine the distance between the screen and the laser 7 and the identification lens 8. In this embodiment, since the distance between the reciprocating mechanism 3 and the machine body 1 and the fixed horizontal support frame 21 is a constant value, when the screen is placed on the fixed horizontal support frame 21, the screen blocks the distance sensor 23 in the horizontal direction, thereby determining the distance between the screen and the reciprocating mechanism 3, thereby improving the accuracy of the laser 7 and the identification lens 8 in scanning and identifying the screen and laser screen.

[0069] Resetting the initial, the reciprocating mechanism 3 is displaced along the length direction of the machine body 1 to the initial position, and the carrier plate 6 is driven to displace to the lowest point of the reciprocating mechanism 3. In this embodiment, the reciprocating mechanism 3 is displaced to the side closest to the control platform and the carrier plate 6 is reset to the lowest position;

[0070] First scanning, when the reciprocating mechanism 3 is driven to displace from one side of the machine body 1 to the other side, the identification lens 8 is driven to scan the screen clamped on the clamping mechanism 2 from bottom to top and from top to bottom in turn;

[0072] Screen making, the reciprocating mechanism 3 and the carrier plate 6 are driven again according to the motion trajectory of the first scanning, the laser 7 performs laser screen making towards the screen, the identification lens 8 synchronously performs secondary scanning on the screen, dynamic focusing is performed on the imaging of the screen, and the laser 7 is fine-tuned according to the focal length of the focusing.

[0073] The distance sensor 23 includes a horizontal distance sensor and a vertical distance sensor,

[0074] The horizontal distance sensor is arranged in an array along the length direction of the fixed horizontal support frame 21 or the moving clamping support frame 22, and is vertically arranged towards the screen, so as to detect the distance between the horizontal distance sensor and the upper and lower edges of the screen when the screen is clamped between the fixed horizontal support frame 21 and the moving clamping support frame 22;

[0075] The horizontal distance sensors are connected through a microprocessor to detect the distance between the first horizontal distance sensor and the nearest horizontal distance sensor that does not respond;

[0076] The vertical distance sensors are arranged along the length direction of the fixed horizontal support 21 or the displacement clamping support, and are arranged towards the displacement clamping support or the fixed clamping support, so as to detect the distance between the fixed horizontal support 21 and the displacement clamping support. In this embodiment, the horizontal distance sensors and the vertical distance sensors are infrared distance sensors or Hall distance sensors, and one is arranged every 10-20 cm along the length direction of the fixed horizontal support 21. In this embodiment, one is arranged every 20 cm, and the horizontal distance sensors and the vertical distance sensors are electrically connected to the microprocessor through a digital-to-analog converter or a code decoder.

First, the microprocessor judges the data difference between the horizontal distance sensors to judge the verticality of the screen. If the data difference between the horizontal distance sensors is ±5 mm, it is judged that the screen is horizontally placed and parallel to the machine body 1 and the reciprocating mechanism 3. When the data difference between the horizontal distance sensors is greater than 5 mm, especially when the data difference between the first and last horizontal distance sensors is greater than 5 mm, it is judged that the distance between the screen and the reciprocating mechanism 3 is uneven. The last horizontal distance sensor refers to the horizontal distance sensor located at the last segment in the horizontal distance sensor in the projection area of the screen. The stroke distance of the reciprocating mechanism 3 in the horizontal direction can be controlled by the microprocessor, which is (N-M+1)*L1, where N is the number of the last horizontal distance sensor in the projection area, M is the first horizontal distance sensor in the projection area, and L1 is the distance between adjacent horizontal distance sensors. Similarly, the stroke distance of the bearing seat in the vertical direction is the distance L2 between the vertical distance sensors relative to the fixed horizontal support 21 or the displacement clamping support.

[0077] The working process is as follows. After selecting the screen, the screen is loaded, and the aperture density specification of the screen is identified through the initial scanning. Then, the set pattern is imaged on the screen by controlling the platform. Then, the device is started, and the reciprocating mechanism 3 drives the identification lens 8 and the laser 7 to reciprocate in the horizontal and vertical directions to perform screen making on the screen. During the screen making process, the reciprocating distance of the reciprocating mechanism 3 is determined according to the interval range obtained by the horizontal distance sensors and the vertical distance sensors to improve the efficiency of screen making. In the entire screen making process, the screen is vertically arranged relative to the ground, and the gravity acting on the screen is expected to be in the same plane, so that the screen making process is not affected by gravity, and the high precision of screen making is ensured. The laser 7 can effectively reduce the energy consumption and power of the laser through the identification of the identification module, and is more energy-saving.
