Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display screen manufacturing, in particular to an automatic uniform speed powder spraying device for LCD glass plates. Background Art
[0002] LCD is the abbreviation of Liquid Crystal Display. The structure of LCD is to place liquid crystals between two parallel ITO conductive glasses. There are many vertical and horizontal thin wires between the two glasses. The direction of the rod-shaped crystal molecules is controlled by whether electricity is turned on or not, so that the light is refracted to produce the picture.
[0003] ITO conductive glass is made by coating a layer of indium tin oxide (commonly known as ITO) on a soda-lime-based or silicon-boron-based substrate glass using magnetron sputtering. ITO conductive glass for LCDs is also coated with a silicon dioxide barrier layer before the ITO layer is coated. After the spraying is completed, the two glass plates are pressed together using a pressing device.
[0004] In the prior art, the spray-deposition of the silica barrier layer is generally completed by a powder spraying device. However, uneven powder spraying by the existing powder spraying device may cause the silica balls to agglomerate, resulting in unevenness between the two glass plates. At the same time, the existing pressing device generally achieves the pressing effect through the air filling hole at the bottom and the gas pressing device. However, the air pressure of the air discharged through the air filling hole will gradually decrease, which will cause the glass at the end close to the air filling hole to be pressed with greater force, and the pressure at the end away from the air filling hole to be smaller, resulting in uneven force.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
[0006] In view of the problems in the related art, the utility model proposes an automatic uniform speed powder spraying device for LCD glass plate to overcome the above technical problems existing in the existing related art.
[0007] To this end, the specific technical solutions adopted by the utility model are as follows:
[0008] An automatic uniform speed powder spraying device for LCD glass plates comprises a fixed frame, wherein both sides of the fixed frame are provided with guide rails, both ends of the guide rails are provided with glass positioning plates, the non-adjacent sides of the two glass positioning plates are provided with pressing mechanisms, and the lower end of the fixed frame is provided with a spraying mechanism.
[0009] Furthermore, the spraying mechanism includes a mounting tube fixedly connected to the fixed frame, a rotating turbine is arranged inside the mounting tube, and a spraying tube is sleeved on the outer side of the mounting tube.
[0010] Furthermore, air outlet holes are provided on both sides of the upper end of the installation tube, and a driving motor connected to the rotating turbine is provided at one end of the installation tube, and the driving motor is fixedly connected to the fixed frame.
[0011] Furthermore, the inner diameter of the spray tube is in contact and rotational connection with the outer diameter of the mounting tube, and a spray pipe is provided at the upper end of the spray tube.
[0012] Furthermore, a strip plate is provided at the lower end of the glass positioning plate away from the pressing mechanism, and a fixed suction cup is provided on the same side of the glass positioning plate as the strip plate.
[0013] Furthermore, the pressing mechanism includes a guide cylinder connected to the mounting cylinder, a push plate is provided on one side of the guide cylinder close to the glass positioning plate, and an air inlet is provided at the bottom of the guide cylinder.
[0014] Furthermore, both lower ends of the fixed frame are provided with spray paint boxes, and one side of the spray paint box is provided with a conduit connected to the spray pipe.
[0015] The utility model provides an automatic uniform speed powder spraying device for LCD glass plate, which has the following beneficial effects:
[0016] The utility model makes the air flow quickly and be discharged through the air outlet by rotating the turbine. When the spraying tube and the spraying pipe rotate and the spraying pipe is connected with the air outlet, the air is led out through the spraying pipe. Since the air outlet is located on both sides of the installation tube, when the spraying pipe is connected with the air outlet, the spraying pipe and the glass plate form a certain angle, thereby achieving the effect of spraying air on the glass plate.
[0017] When the air is ejected from the spray pipe, the silicon balls inside the spray material box are ejected by the siphon principle through the setting of the conduit connected to the spray pipe, so as to achieve the effect of making the air and the silicon balls contact with the glass plate at the same time, thereby achieving the effect of making the silicon balls evenly sprayed on the glass plate.
[0018] By setting the air outlet holes on both sides, when the spray tube is perpendicular to the glass, the air outlet holes are blocked by the spray tube to close the air outlet holes, thereby preventing the silicon balls from being wasted due to vertical spraying.
[0019] Air is injected into the guide cylinder through the air inlet hole, and then the push plate is pushed to one side through the setting of the guide cylinder, thereby achieving the effect of pushing the glass plates to press together. The setting of the pushing plate makes the glass plates move synchronously to ensure that the pressure at each position of the glass plates is the same, thereby preventing the unstable bonding of the two glass plates.

They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0027] According to an embodiment of the utility model, an automatic uniform speed powder spraying device for an LCD glass plate is provided. Example 1
[0028] like Figure 1-3 As shown, the automatic uniform speed powder spraying device for LCD glass plate according to the embodiment of the utility model includes a fixed frame 1, wherein both sides of the fixed frame 1 are provided with guide rails 2, both ends of the inner parts of the two guide rails 2 are commonly provided with glass positioning plates 3, the non-adjacent sides of the two glass positioning plates 3 are provided with pressing mechanisms 4, and the lower end of the inner part of the fixed frame 1 is provided with a spraying mechanism 5.
[0029] When in use, the two glass plates are respectively placed on one side adjacent to the glass positioning plate 3 located on both sides of the fixed frame 1, and the spraying mechanism 5 is set to spray the silicon balls on one surface of the glass through siphoning. When spraying the silicon balls, the wind force generated by the spraying mechanism 5 can blow away the sprayed silicon balls, thereby preventing the uneven fitting of the two glass plates caused by the agglomeration of the silicon balls. After the spraying is completed, the two glass plates are pressed together by the pressing mechanism 4, thereby achieving the effect of fixing the two glass plates. Example 2
[0030] like Figure 1-3 As shown, the spraying mechanism 5 includes a mounting tube 6 fixedly connected to the fixed frame 1, a rotating turbine 7 is arranged inside the mounting tube 6, and a spray tube 8 is sleeved on the outer side of the mounting tube 6. Air outlet holes 9 are opened on both sides of the upper end of the mounting tube 6, and a driving motor 10 connected to the rotating turbine 7 is arranged at one end of the mounting tube 6, and the driving motor 10 is fixedly connected to the fixed frame 1. The inner diameter of the spray tube 8 is in contact and rotationally connected with the outer diameter of the mounting tube 6, and a spray tube 11 is arranged at the upper end of the spray tube 8. A strip plate 12 is arranged at the lower end of the side of the glass positioning plate 3 away from the pressing mechanism 4, and a fixed suction cup 13 is arranged on the same side of the glass positioning plate 3 as the strip plate 12. The pressing mechanism 4 includes a guide tube 14 connected to the mounting tube 6, a push plate 15 is arranged on the side of the guide tube 14 close to the glass positioning plate 3, and an air inlet is arranged at the bottom of the guide tube 14. Both lower ends of the fixed frame 1 are provided with spray paint boxes 16 , and one side of the spray paint boxes 16 is provided with a conduit 17 connected to the spray pipe 11 .
[0031] When in use, the rotating turbine 7 and the spray tube 8 are installed by the installation tube 6, and the rotating turbine 7 is rotated by the setting of the driving motor 10, so that the air is quickly discharged through the air outlet 9, and the spray tube 8 is reciprocated by the reciprocating mechanism set on one side of the driving motor 10. The reciprocating rotation of the spray tube 8 continuously changes the position of the spray tube 11, and then the air discharged from the air outlet 9 is sprayed to the surface of the glass through the position change of the rear spray tube 11. When the spray tube 11 is perpendicular to the glass, the air outlet 9 is blocked by the setting of the spray tube 8 to achieve the effect of closing the air outlet 9, so that the spray The ejection tube 11 cannot eject airflow, and thus cannot eject the silicon balls inside the spray material box 16 through the flow of airflow through the conduit 17, thereby achieving the effect of preventing the silicon balls from being wasted; after the ejection tube 11 continues to rotate, the air outlet 9 on one side is expanded, thereby achieving the effect of spraying to the other side; air is injected into the inside of the guide cylinder 14 through the air inlet, and then the push plate 15 is pushed to one side through the setting of the guide cylinder 14, thereby achieving the effect of pushing the glass plates to be pressed together; through the setting of the push plate 15, the glass plates are moved synchronously to ensure that the pressure at each position of the glass plates is the same, thereby achieving the effect of preventing the two glass plates from being unstable in bonding.
[0032] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0033] In actual application, the two glass plates are placed on one side of the glass positioning plate 3 located on both sides of the fixed frame 1 respectively, and the silicon balls are sprayed on one side of the glass surface by siphoning away through the setting of the spraying mechanism 5. When spraying the silicon balls, the wind force generated by the spraying mechanism 5 can be used to blow away the sprayed silicon balls, thereby preventing the uneven bonding of the two glass plates caused by the agglomeration of the silicon balls. After the spraying is completed, the two glass plates are pressed together through the setting of the pressing mechanism 4, thereby achieving the effect of fixing the two glass plates. When in use, the rotating turbine 7 and the spray tube 8 are installed through the setting of the installation tube 6, and the rotating turbine 7 is rotated through the setting of the driving motor 10, so that the air is quickly discharged through the air outlet 9, and the spray tube 8 is reciprocated by the reciprocating mechanism set on one side of the driving motor 10. The reciprocating rotation of the spray tube 8 makes the position of the spray tube 11 continuously adjusted. The air discharged from the air outlet 9 is changed, and then the position of the rear spray tube 11 is changed to spray the air toward the surface of the glass. When the spray tube 11 is perpendicular to the glass, the air outlet 9 is blocked by the setting of the spray tube 8 to achieve the effect of closing the air outlet 9, so that the spray tube 11 cannot spray out the airflow, and then the silicon balls inside the spray material box 16 cannot be sprayed out through the conduit 17 by the flow of the airflow, thereby achieving the effect of preventing the silicon balls from being wasted. After the spray tube 11 continues to rotate, the air outlet 9 on one side is expanded to achieve the effect of spraying to the other side, and air is injected into the inside of the guide tube 14 through the air inlet, and then the push plate 15 is pushed to one side through the setting of the guide tube 14, thereby achieving the effect of pushing the glass plates to be pressed together, and the glass plates are moved synchronously by the setting of the push plate 15 to ensure that the pressure at each position of the glass plates is the same, thereby preventing the two glass plates from being unstable.
[0034] In summary, with the help of the above-mentioned technical scheme of the utility model, by placing the two glass plates respectively on the adjacent side of the glass positioning plates located on both sides of the fixed frame during use, the silicon balls are sprayed on one surface of the glass through the siphon through the setting of the spraying mechanism, and the wind force generated by the spraying mechanism when spraying the silicon balls can be used to blow away the sprayed silicon balls, thereby preventing the uneven fitting of the two glass plates caused by the agglomeration of the silicon balls. After the spraying is completed, the two glass plates are pressed together through the setting of the pressing mechanism, thereby achieving the effect of fixing the two glass plates.
