DETAILED DESCRIPTION

[0024] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0025] like Figure 1-Figure 3 As shown, a self-adjusting heating adsorption coating platform includes a base 1 and a heating adsorption platform 2 arranged on the base 1, and a plurality of baffles 101 arranged around the heating adsorption platform 2 are provided on the base 1. Gaps are formed between the baffles 101 and the heating adsorption platform 2, and a plurality of adjustment mechanisms 5 for fastening the heating adsorption platform 2 are provided on the baffles 101. The adjustment mechanism 5 includes an adjustment column 501 and a positioning bead 504 elastically arranged at the end of the adjustment column 501. The adjustment column 501 is installed on the baffle 101, and the positioning bead 504 abuts against the side of the heating adsorption platform 2; an insulation board 3 for isolating heat is provided between the base 1 and the heating adsorption platform 2.

[0026] Furthermore, a heat insulation board 3 is provided on the base 1, and the heating adsorption platform 2 is provided on the heat insulation board 3, and the heat insulation board 3 is provided with two layers. Heat insulation is achieved by the heat insulation board 3, thereby ensuring that the heat in the heating adsorption platform 2 will not be transferred to the base 1; the base 1 is a rectangular structure, and the baffles 101 are provided on the four sides of the base 1. The four baffles 101 form a rectangular space, and the heating adsorption platform 2 and the heat insulation board 3 are provided in the rectangular space. The size of the heating adsorption platform 2 is smaller than the size of the rectangular space, and a gap is formed between the heating adsorption platform 2 and the baffle 101. The gap is set so that the heating adsorption platform 2 has expansion space when it expands thermally, ensuring that the coating accuracy of the heating adsorption platform 2 will not be reduced when the heating adsorption platform 2 expands and expands thermally.

[0027] In addition, a number of adjustment mechanisms 5 are provided on the baffle 101, and the several adjustment mechanisms 5 are arranged along the length direction of the baffle 101. The adjustment mechanisms 5 are in contact with the heating adsorption platform 2 to tighten and stabilize the heating adsorption platform 2. When the heating adsorption platform 2 expands and contracts under the influence of temperature, the heating adsorption platform 2 is tightened under the action of the positioning beads 504 and the adjustment springs 502, thereby ensuring the stability of the heating adsorption platform 2, thereby reducing the influence of the thermal expansion and contraction of the heating adsorption platform 2 on the coating accuracy, and improving the coating quality.

[0028] An adjusting groove 5011 is formed in the adjusting column 501 to facilitate the extension and retraction of the positioning bead 504. An adjusting spring 502 is installed in the adjusting groove 5011 to compress the positioning bead 504. Furthermore, an external thread is formed on the outer wall of the adjusting column 501, and a plurality of threaded holes are formed on the baffle 101. The adjusting column 501 is threadedly connected to the threaded holes. The adjusting groove 5011 is arranged along the axial direction of the adjusting column 501, the adjusting spring 502 is arranged inside the adjusting groove 5011, and the positioning bead 504 is arranged at the end of the adjusting groove 5011.

[0029] At the same time, a partition 503 connected to the end of the adjusting spring 502 is provided in the adjusting groove 5011, and the partition 503 is always in contact with the positioning bead 504, and the adjusting spring 502 is connected to the partition 503. The diameter of the positioning bead 504 corresponds to the size of the adjusting groove 5011, and the positioning bead 504 is in contact with the partition 503 and the heating adsorption platform 2. When the heating adsorption platform 2 expands and contracts due to heat and deformation, the positioning bead 504 compresses the adjusting spring 502 under the action of the deformation of the heating adsorption platform 2, so that the adjusting spring 502 is in a compressed state. The elastic force generated by the adjusting spring 502 makes the positioning bead 504 abut against the heating adsorption platform 2, thereby achieving the fastening of the heating adsorption platform 2, ensuring that the heating adsorption platform 2 will not shake, improving the stability of the heating adsorption platform 2, and ensuring that the thermal expansion and contraction of the heating adsorption platform 2 will not affect the coating accuracy, thereby improving the coating quality.

[0030] A heating element 202 is provided in the heating adsorption platform 2, and an exhaust pipe 203 is connected to one side of the heating adsorption platform 2. Furthermore, the heating element 202 is arranged inside the heating adsorption platform 2, and the heating of the heating adsorption platform 2 is achieved through the heating element 202. At the same time, the exhaust pipe 203 is connected to the heating adsorption platform 2, and a plurality of array-distributed suction holes 201 are formed on the surface of the heating adsorption platform 2. The plurality of suction holes 201 are all connected to the exhaust pipe 203, realizing an integrated heating and adsorption setting. In addition, the exhaust pipe 203 is a Teflon tube, which is fastened to the heating adsorption platform 2 by a stainless steel hose clamp.

[0031] The bottom of the base 1 is connected to a horizontal bar 4 for overhead installation of the base 1. The base 1 is provided with a mounting hole 102 for connecting the horizontal bar 4. Furthermore, the base 1 is mounted on the rack table through the horizontal bar 4. The heating adsorption platform 2 is parallel to the rack table. The mounting hole 102 is set on the side of the base 1 for connecting and fixing with the horizontal bar 4.

[0032] The mounting hole 102 is provided with an adjusting stud 103 for adjusting the connection height between the base 1 and the horizontal bar 4, and the adjusting stud 103 is provided with a screw 104 for fastening the base 1 and the horizontal bar 4. Furthermore, the adjusting stud 103 is connected to the mounting hole 102 and the horizontal bar 4, and the adjusting stud 103 is threadedly connected to the mounting hole 102 and the horizontal bar 4. The connection height between the base 1 and the horizontal bar 4 is adjusted by adjusting the stud 103, thereby ensuring that when the horizontal bar 4 is installed on the rack table, the heating adsorption platform 2 remains parallel to the rack table. In addition, a screw 104 is provided in the adjusting stud 103, and the base 1 and the horizontal bar 4 are fastened by the screw 104. At the same time, a heat insulation sheet 105 is provided between the adjusting stud 103 and the horizontal bar 4, and the heat insulation sheet 105 is used to achieve a heat insulation effect between the base 1 and the horizontal bar 4.

[0033] Working principle:

[0034] Before coating, adjust the screws 103 so that the heated adsorption platform 2 is relatively parallel to the frame platform at the bottom of the horizontal bar 4. The glass substrate is then placed on the heated adsorption platform 2. Air is exhausted from the heated adsorption platform 2 through the exhaust pipe 203, generating negative pressure. This negative pressure attracts the glass substrate through the suction holes 201 on the heated adsorption platform. After coating, the heated adsorption platform 2 is heated entirely by the heater 202 within the heated adsorption platform, drying the slurry on the glass substrate through the principle of heat conduction. Due to the principle of heat conduction, the heating adsorption platform 2 will produce the effect of thermal expansion and contraction, resulting in the plane accuracy of the heating adsorption platform 2 failing to meet the specified technical parameters. Therefore, a certain gap is left between the heating adsorption platform 2 and the baffle 101 to ensure that the required technical parameters can be met during thermal expansion and contraction. In addition, the positioning beads 504 are the material of the heating adsorption platform 2. When it is heated and stretched, the positioning beads 504 are squeezed, causing the adjustment spring 502 to be subjected to force and store energy. When the heating adsorption platform 2 stops heating and the material cools down and shrinks, the adjustment spring 502 pushes the positioning beads 504 to rebound. The positioning beads 504 can be tightened even during the period of thermal expansion and contraction of the heating adsorption platform. The insulation board 3 and the insulation sheet 105 are both used to ensure that the heating adsorption platform 2 is isolated from heat during heating, and the entire platform is not affected by the effect of thermal expansion and contraction, thereby further improving the working accuracy of the self-regulating heating adsorption coating platform.
