Description

Technical Field

[0001] This application relates to the field of VFD display manufacturing technology, and in particular to a vacuum coating apparatus for glass plates. Background Technology

[0002] Currently, VFD displays, or vacuum fluorescent displays, are a type of electronic display device. They work by emitting light and displaying information through electrons striking fluorescent materials within a vacuum tube. VFD displays are characterized by high brightness, wide viewing angles, vibrant colors, low operating voltage, and low power consumption. Therefore, they are widely used in applications requiring low power consumption, high brightness, and long lifespan, such as automotive dashboards, audio equipment, and small household appliances.

[0003] In the production of VFD displays, the substrate is a glass plate, which needs to be coated with a film after cleaning. Generally, the glass plate is cleaned by washing and then coated with a planar magnetron sputtering film using vacuum magnetron sputtering.

[0004] Chinese utility model application CN202322488834.9 discloses a glass vacuum coating machine, including a coating machine housing. A movable door is slidably mounted on the front end of the housing via a limiting component. A connecting seat, slidably mounted on the inner side of the front end of the housing, is fixedly connected to the rear surface of the movable door. An mounting seat is fixedly connected to the rear surface of the connecting seat. The connecting seat, mounting seat, and partition facilitate cleaning of the glass surface during use. The connecting seat and partition then seal the glass within the coating chamber, allowing the cleaned glass to be directly coated, thus solving the problem of dust adsorption affecting coating quality.

[0005] After cleaning, moisture may remain on the surface of the glass plate. When the glass plate is then put into the coating machine for coating, the coating effect will be poor. Summary of the Invention

[0006] In order to reduce the moisture on the surface of the glass plate and improve the coating effect of the glass plate, this application provides a vacuum coating apparatus for glass plates.

[0007] This application provides a vacuum coating apparatus for glass plates, which adopts the following technical solution:

[0008] A vacuum coating apparatus for glass plates includes a dehydration chamber, a coating chamber, and a conveying assembly. The dehydration chamber is connected to the coating chamber. The conveying assembly is used to convey the glass plate from the dehydration chamber to the coating chamber. The dehydration chamber is provided with a plurality of heating elements, which are respectively distributed on both sides of the glass plate. The dehydration chamber is connected to a first air extraction component.

[0009] By adopting the above technical solution, after the glass plate is cleaned, it is placed in the dehydration chamber by a conveying component. The heating component heats the glass plate in the dehydration chamber, which removes excess moisture from both sides of the glass plate. The first air extraction component extracts air from the dehydration chamber, which removes water vapor from the dehydration chamber, thereby reducing the moisture on the surface of the glass plate. The conveying component then transports the glass plate to the coating chamber for coating, which can minimize the impact of moisture on the coating of the glass plate and improve the coating effect of the glass plate.

[0010] Preferably, a track is provided at the bottom of the dewatering chamber, one end of which extends into the coating chamber. The conveying assembly includes a sliding block, a fixing plate, and a partition plate. The sliding block is slidably connected to the track along the length of the track. The fixing plate and the partition plate are both disposed on the top of the sliding block. The fixing plate and the partition plate are spaced apart along the distribution direction of the heating element. The partition plate has a first opening.

[0011] By adopting the above technical solution, the glass plate is placed between the fixed plate and the spacer plate, with the first opening of the spacer plate facing the heating element so that the heat from the heating element can be transferred to the glass plate. After the sliding block slides along the track into the coating chamber, it is convenient to coat the side wall of the glass plate.

[0012] Preferably, the coating chamber is connected to a cooling chamber on the side away from the dewatering chamber, one end of the track extends into the cooling chamber, the cooling chamber is provided with multiple heat exchange tubes, each heat exchange tube is filled with coolant, the multiple heat exchange tubes are distributed on both sides of the track, the fixing plate and the partition plate are located between the multiple heat exchange tubes, and the heat exchange tubes are provided with flow valves.

[0013] By adopting the above technical solution, after the glass plate is coated in the coating chamber, the sliding block slides along the track to the cooling chamber. The coolant flows in the heat exchange tube, which cools the cooling chamber and the glass plate. The flow rate of the coolant in the heat exchange tube can be adjusted by adjusting the flow valve, so that the glass plate can be cooled slowly, which can avoid affecting the quality of the glass plate due to excessive cooling. After the glass plate is cooled, the staff takes it out of the cooling chamber.

[0014] Preferably, there are two spacers, which are located on both sides of the fixed plate. The coating chamber is provided with a switch door on both sides of the track. An aluminum plate is provided on one side of the switch door. The aluminum plate is located on the side of the spacer away from the fixed plate. The coating chamber is connected to a second exhaust device and an argon gas source. A baffle plate is provided between the aluminum plate and the spacer. The aluminum plate, the baffle plate and the spacer are arranged parallel to each other. The baffle plate has a second opening.

[0015] By adopting the above technical solution, glass plates can be placed between the two partition plates and the fixed plate. After the door is closed, the aluminum plate is located on one side of the partition plate. The second vacuum device evacuates the coating chamber, and the argon gas source inputs argon gas into the coating chamber, so that one side of the glass plate can be coated. The baffle plate can block the glass plate, so that the side wall of the glass plate facing the second opening can be coated, which can improve the quality of the coated glass plate.

[0016] Preferably, the top of the sliding block is provided with a receiving groove for inserting a glass plate, and the side walls of the spacer and the fixed plate that are close to each other are provided with flexible strips. The spacer is provided with a driving assembly, which is used to move the spacer to move the spacer closer to or away from the fixed plate.

[0017] By adopting the above technical solution, the drive component moves the spacer away from the fixed plate. After the bottom of the glass plate is inserted into the receiving groove, the drive component moves the spacer closer to the fixed plate. Both the spacer and the fixed plate are held against the sides of the glass plate by flexible strips, which can improve the stability of the glass plate during coating and improve the coating quality.

[0018] Preferably, the driving assembly includes a vacuum pump and a flexible sleeve. The flexible sleeve is located between the spacer plate and the fixed plate. Both ends of the flexible sleeve are connected to the side wall of the spacer plate and the side wall of the fixed plate, respectively. An air passage is provided inside the fixed plate. One end of the air passage is connected to the flexible sleeve, and the vacuum pump is connected to the other end of the air passage.

[0019] By adopting the above technical solution, the flexible sleeve is connected to the spacer plate and the fixed plate at both ends. When the vacuum pump pumps air into the flexible sleeve through the air passage, the gas inside the flexible sleeve is extracted, and the flexible sleeve contracts to pull the spacer plate toward the fixed plate. The spacer plate can thus get closer to the fixed plate. When the vacuum pump supplies air into the flexible sleeve through the air passage, the flexible sleeve is filled with air and expands. The flexible sleeve pushes the spacer plate in this way, and the spacer plate can thus move away from the fixed plate.

[0020] Preferably, the bottom of the receiving groove has multiple through holes, which are evenly distributed. The end of the sliding block near the heating element has a vent, and each through hole is connected to the vent.

[0021] By adopting the above technical solution, the heat emitted by the heating element can enter the receiving groove through the vent and through hole to heat the bottom of the glass plate, which can accelerate the air circulation at the bottom of the glass plate and thus improve the water removal efficiency of the glass plate.

[0022] Preferably, the side wall of the receiving groove near the fixed plate is vertically planar, the side wall of the receiving groove near the partition plate is inclined, and the top opening width of the receiving groove is greater than the bottom width.

[0023] By adopting the above technical solution, the drive component moves the spacer away from the fixed plate. When the bottom of the glass plate is inserted into the receiving groove, the top of the glass plate can be reliably placed on the flexible strip of the spacer, which can make the glass plate tilted. This reduces the contact area between the glass plate and the spacer and the fixed plate, making it easier to remove water from the glass plate. The drive component moves the spacer closer to the fixed plate, and the spacer can drive the glass plate to make the glass plate vertical. Both the spacer and the fixed plate are fixed to the glass plate by the flexible strip, which facilitates the coating of the glass plate.

[0024] Preferably, the top of the sliding block is provided with a receiving groove for inserting a glass plate, and the side walls of the spacer plate and the fixed plate that are close to each other are provided with multiple airbags, and each airbag is distributed in a dot matrix.

[0025] By adopting the above technical solution, after the bottom of the glass plate is inserted into the receiving groove, the spacer plate and the fixing plate are both held against the sides of the glass plate by airbags, which can improve the stability of the glass plate during coating and improve the coating quality.

[0026] Preferably, each of the airbags is connected to an air supply pipe and an air outlet pipe, the air supply pipe is equipped with a first solenoid valve, the air outlet pipe is equipped with a second solenoid valve, and the air supply pipe is connected to an inflation pump.

[0027] By adopting the above technical solution, when the first solenoid valve is open and the second solenoid valve is closed, the air pump can inflate the airbag through the air supply pipe, and the airbag can expand and press against the glass plate, thereby fixing the glass plate. When the first solenoid valve is closed and the second solenoid valve is open, the gas in the airbag can be discharged through the air outlet pipe, and the airbag can deflate, thereby facilitating the removal of the glass plate from between the partition plate and the fixing plate.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. After cleaning, the glass plate is placed in the dehydration chamber by a conveying assembly. The heating element heats the glass plate in the dehydration chamber, which removes excess moisture from both sides of the glass plate. The first air extraction element extracts air from the dehydration chamber, which removes water vapor from the dehydration chamber, thereby reducing the moisture on the surface of the glass plate. The conveying assembly then transports the glass plate to the coating chamber for coating, which can minimize the impact of moisture on the coating of the glass plate and improve the coating effect of the glass plate.

[0030] 2. After the glass plate is coated in the coating chamber, the sliding block slides along the track to the cooling chamber. The coolant flows in the heat exchange tubes, which in turn cool the cooling chamber and the glass plate. The flow rate of the coolant in the heat exchange tubes can be adjusted by adjusting the flow valve, so that the glass plate can be cooled slowly, which can avoid affecting the quality of the glass plate due to excessive cooling. After the glass plate has cooled down, the staff takes the glass plate out of the cooling chamber.

[0031] 3. When the drive assembly moves the spacer away from the fixed plate, the bottom of the glass plate is inserted into the receiving groove, and the top of the glass plate rests on the flexible strip of the spacer, allowing the glass plate to be tilted. This reduces the contact area between the glass plate and the spacer and fixed plate, facilitating the removal of water from the glass plate. When the drive assembly moves the spacer closer to the fixed plate, the spacer can move the glass plate to make it vertical. Both the spacer and the fixed plate are fixed to the glass plate by the flexible strip, which facilitates the coating of the glass plate. Attached Figure Description

[0048] The present application will be further described in detail below with reference to all the accompanying drawings.

[0049] This application discloses a vacuum coating apparatus for glass plates.

[0050] Example 1:

[0051] Reference Figure 1 and Figure 2 The glass plate vacuum coating device includes a dehydration chamber 100, a coating chamber 200, a cooling chamber 300, and a conveying assembly 400. The two ends of the coating chamber 200 are connected to the dehydration chamber 100 and the cooling chamber 300, respectively. The conveying assembly 400 is used to convey the glass plate through the dehydration chamber 100, the coating chamber 200, and the cooling chamber 300 in sequence. The dehydration chamber 100 is used to remove excess water from the surface of the glass plate. The coating chamber 200 is used to coat the surface of the glass plate. The cooling chamber 300 is used to cool the glass plate.

[0052] Reference Figure 1 , Figure 2 and Figure 3 The top of the dehydration chamber 100 is connected to a first air extraction component 102, which is an air extraction pump that can extract air from the dehydration chamber 100. A track 500 is installed at the bottom of the dehydration chamber 100, with one end of the track 500 passing through the coating chamber 200 and located in the cooling chamber 300. The conveying assembly 400 conveys the glass plate through the track 500. Heating elements 101, which are electric heating wires, are installed on both sides of the dehydration chamber 100 to increase the temperature within the dehydration chamber 100.

[0053] Both ends of the dewatering chamber 100 and the cooling chamber 300 are equipped with sealed doors. When the sealed doors are opened, the dewatering chamber 100, the coating chamber 200 and the cooling chamber 300 are connected. The conveying assembly 400 can then convey the glass plate through the dewatering chamber 100, the coating chamber 200 and the cooling chamber 300 in sequence.

[0054] Reference Figure 2 , Figure 4 and Figure 5The conveying assembly 400 includes a sliding block 401, a fixed plate 402, and two partition plates 403. The sliding block 401 is slidably connected to the top of the track 500 along the length of the track 500. The sliding block 401 is driven by a lead screw. In other embodiments, the sliding block 401 is driven by a linear motor. The fixed plate 402 and the partition plates 403 are both rectangular and are located on the top of the sliding block 401. Both partition plates 403 have a first opening 404. The fixed plate 402 is vertically arranged and parallel to the side wall of the dewatering chamber 100 where the heating element 101 is located. The bottom end of the fixed plate 402 is connected to the center of the top of the sliding block 401. The two partition plates 403 are located on both sides of the fixed plate 402, and the bottom of the two partition plates 403 are spaced apart from the top of the sliding block 401. The sidewalls of the partition plate 403 and the fixing plate 402 that are close to each other are each provided with a plurality of flexible strips 600 distributed circumferentially along the first opening 404. The flexible strips 600 are made of sponge strips. In other embodiments, the flexible strips 600 are made of rubber strips.

[0055] The sliding block 401 has two receiving grooves 405 on its top, located between the fixed plate 402 and the two partition plates 403. The sidewall of the receiving groove 405 near the fixed plate 402 is vertically planar, while the sidewall of the receiving groove 405 near the partition plate 403 is inclined. The opening width at the top of the receiving groove 405 is greater than the width at the bottom. In other embodiments, the sidewall of the receiving groove 405 near the partition plate 403 is arc-shaped with the convex arc side facing the partition plate 403. Multiple through holes 407 are provided at the bottom of the receiving groove 405, evenly spaced along its length. A vent 408 is provided at the end of the sliding block 401 near the heating element 101, with two vents 408 communicating with each other and with each through hole 407.

[0056] Both partition plates 403 are equipped with drive assemblies 800, each including a vacuum pump 802 and a flexible sleeve 801. The flexible sleeve 801 is made of rubber and is located between the partition plate 403 and the fixed plate 402. The flexible sleeve 801 has a hollow interior. One end of the flexible sleeve 801 is connected to the side wall of the partition plate 403 near the fixed plate 402, and the other end is connected to the side wall of the fixed plate 402 near the partition plate 403. The vacuum pump 802 is connected to the top of the fixed plate 402. An air passage 406 is provided inside the fixed plate 402. One end of the air passage 406 is connected to the vacuum pump 802, and the other end is connected to the flexible sleeve 801.

[0057] Reference Figure 1 , Figure 2 and Figure 3Multiple coating chambers 200 are arranged sequentially and connected. Each coating chamber 200 has a rotatable door 201 mounted on each side wall of the track 500. The door 201 rotates to open and close the coating chamber 200. The door 201 is vertically positioned and connected to an aluminum plate 202 on its inner side. The aluminum plate 202 is vertically positioned on the side of the partition plate 403 away from the fixed plate 402. After the door 201 is closed, the aluminum plate 202 is parallel to the fixed plate 402. A baffle plate 205 is provided in each coating chamber 200, located between the aluminum plate 202 and the partition plate 403, and parallel to the aluminum plate 202. The baffle plate 205 has a second opening 206, which is directly opposite the first opening 404.

[0058] The top of the coating chamber 200 is connected to a second vacuum pump 203 and an argon source 204. The second vacuum pump 203 is used to evacuate the coating chamber 200. The argon source 204 is used to supply argon gas to the coating chamber 200. The argon source 204 is a pipe through which argon gas flows.

[0059] Reference Figure 1 , Figure 2 and Figure 3 The cooling chamber 300 is equipped with heat exchange pipes 301 on both sides of the track 500. One end of the heat exchange pipe 301 extends out of the cooling chamber 300 and is equipped with a flow valve and connected to a delivery pump. The delivery pump is used to deliver coolant to the heat exchange pipe 301. In this embodiment, the coolant is cold water. The other end of the heat exchange pipe 301 extends out of the cooling chamber 300 and is connected to a recovery tank.

[0060] The implementation principle of Example 1 is as follows: Vacuum pump 802 inflates the flexible sleeve 801, causing it to expand. The spacer 403 moves away from the fixed plate 402. The operator inserts the bottom of the glass plate into the receiving groove 405, with the bottom of the glass plate close to the vertical side wall of the receiving groove 405 and the top of the glass plate leaning against the flexible strip 600 of the spacer 403. The heating element 101 heats the dehydration chamber 100, removing moisture from the surface of the glass plate. The sliding block 401 moves into the coating chamber 200, and vacuum pump 802 evacuates the flexible sleeve 801, causing it to deflate. The flexible sleeve 801 pulls the spacer 403 closer to the fixed plate 402 until the spacer 403 and the flexible strip 600 of the fixed plate 402 clamp the two sides of the glass plate, at which point the glass plate is in a vertical position. After the second vacuum pump 203 evacuates the coating chamber 200, the argon source 204 supplies argon gas into the coating chamber 200. The argon gas is then deposited onto one side of the glass plate through the aluminum plate 202. After the glass plate is coated, the sliding block 401 moves to the cooling chamber 300. The vacuum pump 802 fills the flexible sleeve 801 with gas, causing the flexible sleeve 801 to expand. The spacer 403 moves away from the fixed plate 402, and the glass plate cools in the cooling chamber 300, thereby reducing the temperature of the glass plate. After the glass plate has cooled, the operator removes the glass plate from between the fixed plate 402 and the spacer 403.

[0061] Example 2: The difference between it and Example 1 is that the connection between the partition plate 403 and the sliding block 401 is different.

[0062] Reference Figure 5 The glass plate vacuum coating device includes a conveying assembly 400, which includes a sliding block 401, a fixed plate 402, and two spacer plates 403. The fixed plate 402 and the spacer plates 403 are both vertically arranged and parallel to each other. The bottom of the fixed plate 402 and the bottom of the spacer plates 403 are fixedly connected to the top of the sliding block 401. The two spacer plates 403 are located on both sides of the fixed plate 402, and the fixed plate 402 and the two spacer plates 403 are distributed at equal intervals.

[0063] Four airbags 700 are connected to both side walls of the fixed plate 402 and the side wall of the partition plate 403 near the fixed plate 402. The airbags 700 are made of rubber and are arranged in a rectangular dot matrix. The airbags 700 on the partition plate 403 correspond one-to-one with the airbags 700 on the fixed plate 402. Each airbag 700 is connected to an air supply pipe 701 and an air outlet pipe 702. The air supply pipe 701 is connected to an air pump 705, which is connected to the fixed plate 402. The air supply pipe 701 is equipped with a first solenoid valve 703. When the first solenoid valve 703 is opened, the air pump 705 can inflate the airbag 700 through the air supply pipe 701. The air outlet pipe 702 is equipped with a second solenoid valve 704. When the second solenoid valve 704 is opened, the gas in the airbag 700 can be discharged.

[0064] The implementation principle of Example 2 is as follows: After the second solenoid valve 704 is opened, the gas in the airbag 700 can be discharged, making it easier for the operator to insert the bottom of the glass plate into the receiving groove 405. When the second solenoid valve 704 is closed, the air pump 705 fills the airbag 700 with some gas. At this time, the airbag 700 does not press against the glass plate. When the first solenoid valve 703 is closed, the heating element 101 can heat the dehydration chamber 100 to remove moisture from the surface of the glass plate. The sliding block 401 moves into the coating chamber 200, and the second vacuum element 203 evacuates the coating chamber 200. The airbag 700 expands under negative pressure. The spacer plate 403 and the airbag 700 of the fixed plate 402 clamp the two sides of the glass plate, at which time the glass plate is in a vertical state. Argon source 204 supplies argon gas into coating chamber 200. After coating the glass plate, sliding block 401 moves to cooling chamber 300, airbag 700 deflates, and cooling chamber 300 can cool the glass plate.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
