[0002] A glass backplane is a glass substrate used to support and protect devices or components. It is commonly used in electronic devices, solar panels, etc. The glass backplane can provide mechanical strength and stability, support the overall structure of the device, and protect internal components from physical damage and environmental influences (such as moisture, dust, etc.). In some applications, the glass backplane also acts as an electrical insulator to prevent current leakage and short circuits.

[0003] In the prior art, bubbles are generated during the production of glass back panels. These bubbles will affect the mechanical strength, optical properties, and electrical properties of the glass. Therefore, these bubbles must be eliminated through a debubbling process, and the debubbling effect is generally achieved by heating and vacuuming. Since the internal heating device is fixed in a stationary position, local overheating or uneven heating of the glass back panel is prone to occur, thereby reducing the debubbling effect of the glass back panel. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the existing equipment is in use, local overheating or uneven heating of the glass back plate may occur due to the internal heating device being fixed in position. A defoaming device for glass back plate production is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a debubbling device for glass back panel production, comprising a debubbling box, the back of the debubbling box is in contact with a vacuum pump, a connecting pipe is fixedly installed on the top of the vacuum pump, and the output end of the connecting pipe is connected to the interior of the debubbling box, a first forward and reverse motor is fixedly installed on one side of the inner wall of the debubbling box, a threaded rod is fixedly installed on one side of the outer wall of the first forward and reverse motor, a limiting column is fixedly installed on the bottom of the inner wall of the debubbling box, and the outer wall of the threaded rod is movably inserted into the interior of the limiting column, the outer wall of the threaded rod is threadedly connected to a movable frame, a guide rod is fixedly installed between the inner walls of the debubbling box, and the inner wall of the movable frame is movably sleeved on the outer wall of the guide rod, and a heater is fixedly installed on the bottom of the inner wall of the movable frame.

[0007] Preferably, the inner surface wall of the defoaming box is provided with two strip-shaped grooves, and the inner surface walls of the two strip-shaped grooves are both movably embedded with strip-shaped blocks.

[0008] Preferably, a placement plate is fixedly installed between opposite sides of the outer walls of the two strip blocks, and two tooth rows are fixedly installed on the top of the placement plate.

[0009] Preferably, the inner surface wall of the defoaming box is provided with two placement grooves.

[0010] Preferably, a second forward and reverse motor is fixedly mounted on the bottom of the inner wall of each of the two placement slots, and a driving rod is fixedly mounted on one side of the outer wall of each of the two second forward and reverse motors.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] In the utility model, the glass back panel that needs to remove bubbles is placed in the placement frame, and then the heater and the first forward and reverse motor are started by the controller, and the first forward and reverse motor drives the threaded rod to rotate inside the limit column. Under the action of the guide rod, the movable frame is stably moved back and forth on the threaded rod and the guide rod, so that the heater in the movable frame can evenly heat the glass back panel during the heating process, avoid heat concentration in a certain part, and prevent local overheating. Under the action of the temperature sensor, according to the type of the glass back panel, continuous heating is performed to make the interior reach the optimal softening temperature for debubbling, and then the vacuum pump is started to extract the air in the debubbling box to create a vacuum environment. Under the action of the timer, the vacuum and heating state are maintained for a certain period of time to ensure that the bubbles are completely discharged, thereby improving the debubbling effect of the glass back panel.

[0017] In the utility model, after the glass back panel in the placement frame is heated and debubbled, the two second forward and reverse motors are started to drive the two driving rods to rotate, thereby driving the two gear rows to move.

[0025] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless there is a conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, as Figure 1-Figure 5As shown, the utility model provides a degassing device for glass backboard production, including a degassing box 1, the back of the degassing box 1 is in contact with a vacuum pump 2, the top of the vacuum pump 2 is fixedly installed with a connecting pipe 3, and the output end of the connecting pipe 3 is connected to the interior of the degassing box 1, the inner wall side of the degassing box 1 is fixedly installed with a first forward and reverse motor 4, the outer wall side of the first forward and reverse motor 4 is fixedly installed with a threaded rod 5, the bottom of the inner wall of the degassing box 1 is fixedly installed with a limiting column 6, and the outer wall of the threaded rod 5 is movably inserted in the inner part of the limiting column 6, the outer wall of the threaded rod 5 is threadedly connected with a moving frame 7, a guide rod 8 is fixedly installed between the inner walls of the degassing box 1, and the inner wall of the moving frame 7 is movably sleeved on the outer wall of the guide rod 8, a heater 9 is fixedly installed on the inner wall bottom of the moving frame 7, a temperature sensor 10 is fixedly installed on one side of the inner wall of the degassing box 1, a controller 11 is fixedly installed on one side of the outer wall of the degassing box 1, and the outer wall side of the controller 11 is electrically connected to the outer wall of the temperature sensor 10.

[0028] The effect achieved by the entire embodiment 1 is that when it is necessary to remove bubbles on the glass back panel, the glass back panel is placed in the placement frame 21, and then the visual door 23 is closed. Since the controller 11 and the first forward and reverse motor 4 and the heater 9 are all electrically connected, the first forward and reverse motor 4 and the heater 9 are started simultaneously by the controller 11, and the threaded rod 5 is driven to rotate inside the limit column 6 at the end away from the first forward and reverse motor 4. Because a guide rod 8 is installed between the inner surface walls of the debubble box 1, its movable frame 7 is threadedly connected to the threaded rod 5 and is also movably sleeved on the guide rod 8, so that the movable frame 7 can stably move back and forth on the threaded rod 5 and the guide rod 8, so that the heater 9 in the movable frame 7 can evenly heat the glass back panel back and forth, so that the heat is evenly distributed. On the glass back panel, in order to avoid heat concentration in a certain part and prevent local overheating, a temperature sensor 10 is fixedly installed on one side of the inner wall of the debubble box 1. Through the function of the temperature sensor 10, the temperature inside the debubble box 1 can be monitored at all times, and according to the type of the glass back panel, the heater 9 is continuously heated to the optimal softening temperature range of the glass back panel. Then, the vacuum pump 2 in contact with one side of the outer wall of the debubble box 1 is started, and under the action of the connecting pipe 3, a vacuum environment is achieved in the debubble box 1. Because a timer 22 is fixedly installed on the top of the debubble box 1, the timer 22 allows the staff to maintain the vacuum and heating state in the debubble box 1 for a certain period of time and ensure that the bubbles in the glass back panel are completely discharged, thereby improving the debubble effect of the glass back panel after production.

[0029] Example 2, as Figure 2-Figure 5As shown, the inner surface wall of the de-bubble box 1 is provided with two strip grooves 12, and the inner surface walls of the two strip grooves 12 are movably embedded with strip blocks 13, and a placement plate 14 is fixedly installed between the opposite sides of the outer walls of the two strip blocks 13, and two gear rows 15 are fixedly installed on the top of the placement plate 14. The inner surface wall of the de-bubble box 1 is provided with two placement grooves 16, and the bottom of the inner walls of the two placement grooves 16 are fixedly installed with a second forward and reverse motor 17, and one side of the outer wall of the two second forward and reverse motors 17 is fixedly installed with a driving rod 18, and the outer walls of the two driving rods 18 are fixedly installed with gears 19, and the outer walls of the two gears 19 are meshed with the tops of the two gear rows 15, and one side of the outer wall of the two gear rows 15 is fixedly installed with a stopper 20, a placement frame 21 is fixedly installed on the top of the placement plate 14, a timer 22 is fixedly installed on the top of the de-bubble box 1, and a visual door 23 is provided on one side of the outer wall of the de-bubble box 1.

[0030] The effect achieved by the entire embodiment 2 is that, when the glass back plate in the placement frame 21 is defoamed and needs to be taken out, two placement grooves 16 are provided on the inner surface wall of the defoaming box 1, and second forward and reverse motors 17 are fixedly installed at the bottom of the inner walls of the two placement grooves 16. The two second forward and reverse motors 17 are started to drive the two driving rods 18 to rotate. Since the outer walls of the two driving rods 18 are fixedly sleeved with gears 19, the two gears 19 are driven to rotate. Then, two strip grooves 12 are provided on the inner surface wall of the defoaming box 1, and strip blocks 13 are movably embedded in the inner surface walls of the two strip grooves 12, and the outer walls of the two strip blocks 13 are opposite to each other. A placement plate 14 is installed between them, and two tooth rows 15 are installed on the placement plate 14, and the outer walls of the two gears 19 are meshed with the tops of the two tooth rows 15, so that the two tooth rows 15 can be driven to move outward by the rotation of the two gears 19. Since a stopper 20 is installed on one side of the outer wall of the two tooth rows 15, and the action of the two stoppers 20 effectively prevents the two tooth rows 15 from being separated from the two gears 19, the smoothness of the movement of the placement plate 14 and the two bar blocks 13 is ensured, so that the staff does not need to reach inside with their hands to take out the glass back panel after the bubbles are removed, which can avoid burns to the staff, thereby improving the use effect of the degassing device.

[0031] Working principle: First, when it is necessary to remove bubbles from the produced glass back panel, place the glass back panel in the placement frame 21, then close the visual door 23, and start the heater 9 and the first forward and reverse motor 4 through the controller 11 installed on the outer wall of the bubble removal box 1. Since the moving frame 7 is movably sleeved on the guide rod 8 and is also threadedly connected to the threaded rod 5, the threaded rod 5 is driven to rotate by the first forward and reverse motor 4, so that the moving frame 7 moves back and forth on the threaded rod 5 and the guide rod 8 at the same time, and the heater 9 in the moving frame 7 moves back and forth to the placement panel. 14 and the glass back plate are evenly heated to avoid heat concentration in a certain part and prevent local overheating, so that the glass back plate is softened evenly. Then, a temperature sensor 10 is installed on one side of the inner wall of the debubble box 1, and the controller 11 and the heater 9 cooperate with each other, and according to the type and specification of the glass back plate, the heater 9 is continuously heated to the optimal softening temperature for debubbling the glass back plate. Then, the vacuum pump 2 in contact with one side of the outer wall of the debubble box 1 is started, and under the action of the connecting pipe 3, the air in the debubble box 1 can be extracted to create a vacuum. The environment makes the bubbles inside the glass back plate expand and rise to the surface, and finally discharged from the surface of the glass back plate. Because a timer 22 is fixed on the top of the debubble box 1, and under the action of the timer 22, the debubble box 1 is kept in a vacuum and heating state for a certain period of time, thereby ensuring that the bubbles in the glass back plate are completely discharged, thereby improving the debubble effect of the glass back plate. Secondly, when the debubble of the glass back plate is completed, the second forward and reverse motor 17 installed in the two placement slots 16 is started to drive the two driving rods 18 and the two gears 19 to rotate. Since two strip grooves 12 are provided on the inner surface wall of the defoaming box 1, and the strip blocks 13 installed on both sides of the placement plate 14 are movably embedded in the two strip grooves 12, and the outer surfaces of the two gears 19 are meshed with the two tooth rows 15 installed on the top of the placement plate 14, so that the rotation of the two gears 19 can drive the two tooth rows 15 and the placement plate 14 to move outward, without the need for staff to reach inside to take and place the glass back panel, which can avoid burns to the staff and further improve the use effect of the glass back panel defoaming device.
