DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-5 As shown in the figure, the embodiment provides a glass exposure machine temperature equalization control device, which comprises an exposure machine body 100. Considering that the existing air guide structure and air flow distribution mode may not be optimized enough, leading to uneven temperature distribution on the surface of the glass substrate. In some high-precision exposure processes, such temperature unevenness may have a significant impact on product quality, therefore, the exposure machine body 100 is provided with a mounting seat 101 at the inside, the mounting seat 101 is provided with a workbench 1010 at the top end, the workbench 1010 is provided with a cavity 1011 at the inside, the cavity 1011 is rotatably connected with a support shaft 1012 at the inside, the support shaft 1012 is provided with a plurality of fan blades 1013 on the outer wall, the exposure machine body 100 is provided with a drive motor 102 at the inside, the drive motor 102 is provided with an output end penetrating through the workbench 1010 to the inside of the cavity 1011, and is connected with the support shaft 1012, and the upper surface of the workbench 1010 is provided with a plurality of air vents 1014.

[0022] The upper surface of the workbench 1010 is provided with a plurality of air guide assemblies 200 in annular array, the air guide assemblies 200 are four in number, the air guide assemblies 200 are used for controlling the temperature by blowing air from the side and the top of the glass substrate, the limiting assembly 300 is installed at the bottom end of the side wall of the air guide assembly 200, and the limiting assembly 300 is used for limiting the glass substrate of different sizes.

[0023] The improvement of the embodiment is that:

[0024] On the one hand, by arranging the air guide assembly 200 on the upper surface of the workbench 1010 in a ring array, the air from the cavity 1011 can be precisely guided to the side and top of the glass substrate. This precise guidance can ensure that the air can directly act on the key parts of the glass substrate that need to be temperature controlled, improve the utilization rate of the air, and enhance the effect of temperature uniformity control. On the other hand, the limiting assembly 300 limits the glass substrate of different sizes. It can ensure that the glass substrate is in the correct position on the workbench 1010, so that the air guide assembly 200 can accurately blow and control the temperature of the glass substrate. Regardless of the size of the glass substrate, the limiting assembly 300 can fix it in the right place to ensure the accuracy and effectiveness of temperature uniformity control.

[0025] First, in order to blow and control the temperature of the side and top of the glass substrate and prevent overheating, the air guide assembly 200 includes an air guide plate 201, the top end of the air guide plate 201 is provided with a guide plate 2010, the guide plate 2010 is arranged at an inclined angle, and a plurality of grooves 2011 are formed on the surface of the air guide plate 201, the air guide plate 201 and the guide plate 2010 are communicated, and the bottom end of the air guide plate 201 is communicated with the air hole 1014 and the cavity 1011;

[0026] The air from the cavity 1011 is guided to the glass substrate through the air guide plate 201. Its top end is communicated with the guide plate 2010, and its bottom end is communicated with the air hole 1014 and the cavity 1011, forming an efficient air flow channel. After the air enters the air guide plate 201 from the cavity 1011, it flows along the specified path of the air guide plate 201, which can be more evenly distributed on the surface of the glass substrate, ensuring that each part of the glass substrate can be fully blown by the air, and realizing more accurate temperature uniformity control; the existence of the grooves 2011 can reduce the thickness of the boundary layer of the airflow, making the heat transfer more rapid, which is helpful for rapid temperature adjustment of the glass substrate; the guide plate 2010 is arranged at an inclined angle, which can effectively adjust the direction of the airflow. When the air enters the guide plate 2010 from the air guide plate 201, the inclined guide plate 2010 will change the direction of the airflow, so that it can be more precisely blown to the part of the glass substrate that needs to be temperature controlled. At the same time, the inclined design of the guide plate 2010 can reduce the direct impact of the airflow on the glass substrate. If the airflow directly vertically blows to the glass substrate, it may form a larger pressure fluctuation on the surface of the glass substrate, resulting in uneven temperature distribution of the glass substrate. The inclined angle of the guide plate 2010 can make the airflow contact the glass substrate in a more gentle way, reduce the pressure fluctuation, reduce the interference of the airflow on the glass substrate, and make the temperature uniformity control more stable.

[0027] Secondly, in order to limit the size of the glass base, the limiting assembly 300 includes a threaded rod 301 and a baffle 302, the outer wall of the threaded rod 301 is screwed with the air deflector 201, one end of the threaded rod 301 is rotatably connected with the surface of the baffle 302, and the other end of the threaded rod 301 is provided with a torsion block 3010. The operator only needs to hold the torsion block 3010 and control the rotation of the threaded rod 301 by manually rotating, so that the threaded rod 301 moves forward and backward in the threaded hole of the air deflector 201, thereby driving the baffle 302 to accurately approach or move away from the glass substrate. This fine adjustment capability can be customized according to different sizes of the glass substrate, so that the glass substrate is always in the right position on the workbench 1010, so as to achieve the best temperature balancing control effect.

[0028] In specific use, the glass exposure machine temperature balancing control device of the utility model, the staff places the glass substrate to be exposed on the workbench 1010, according to the size of the glass substrate, the threaded rod 301 in the limiting assembly 300 is adjusted by twisting the torsion block 3010, so that the baffle 302 moves to the appropriate position, and the glass substrate is fixed and limited, so that displacement does not occur during the work. Turn on the drive motor 102, the drive motor 102 drives the support shaft 1012 to rotate, the fan blade 1013 on the support shaft 1012 rotates, and air flow is generated. The air flow enters the cavity 1011 through the air hole 1014 on the workbench 1010, and forms an air circulation system in the cavity 1011. The air in the cavity 1011 passes through the channel between the air deflector 201 and the guide plate 2010 of the air deflector assembly 200 and the groove 2011 on the air deflector 201, and is guided to the side and top of the glass substrate. Since the drive motor 102 can accurately control the rotation speed of the fan blade 1013, the air speed can be adjusted according to the information fed back by the real-time temperature sensor of the glass substrate. If the temperature of the glass substrate is high, the air speed can be increased to enhance heat dissipation; if the temperature is low, the air speed can be reduced or stopped for a period of time, so that the temperature of the glass substrate reaches the appropriate range. During the exposure process, the temperature of the glass substrate is continuously monitored by the temperature sensor. If the temperature deviates, the air volume and direction are changed by adjusting the rotation speed of the drive motor 102 in time, so as to further adjust the temperature of the glass substrate, and ensure that the temperature of the glass substrate is always maintained in the set uniform and appropriate range during the entire exposure process.
