Description

Technical Field

[0001] This invention relates to the field of glass production technology, specifically to a sealing device and sealing process for the production of double-layer vacuum glass. Background Technology

[0002] Double-glazed vacuum glass typically consists of two panes of glass with a cavity between them. Sealant is applied around the perimeter of the glass panes, and the cavity is evacuated to create a vacuum layer. Double-glazed vacuum glass offers advantages such as sound and heat insulation, noise reduction, high wind pressure resistance, thinness, and long service life.

[0003] Patent publication number CN116514416A discloses a sealing process for the production of double-layered glass, including the following steps: an evacuation hole is opened on the surface of the upper glass layer, and a zinc alloy ring is installed inside the evacuation hole; a first and third annular sealing strips are set at the bottom of the upper glass layer, and two second and two fourth annular sealing strips are set at the top of the lower glass layer, with low-temperature glass solder filling between the two second annular sealing strips; the double-layered glass is transported to a double-layered glass sealing box; the box is evacuated to below 0.1 Pa, and the upper and lower heating plates are turned on to heat the double-layered glass. The molten zinc alloy rings flow into the space between the two fourth annular sealing strips to seal the edge of the evacuation hole, and then the molten low-temperature glass solder seals the edge of the double-layered glass. This sealing process eliminates the need for subsequent vacuuming after sealing, avoids the need to block the evacuation hole, simplifies the sealing process for double-layered vacuum glass, and ensures the vacuum level of the double-layered vacuum glass.

[0004] However, the current sealing device has the following problems: When sealing double-glazed glass, the glass needs to be placed manually between the upper and lower heating plates inside the device, which is relatively cumbersome and reduces the production efficiency of double-glazed glass sealing; when the two pieces of glass need to be placed and processed separately, dust and other impurities are easily attached to the surface of the lower glass when placed manually. These impurities will affect the sealing effect and reduce the performance of the double-glazed glass. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing device and sealing process for the production of double-layer vacuum glass, so as to solve the problem that when sealing double-layer vacuum glass, it is necessary to manually place the two pieces of glass between the upper and lower heating plates inside the device, which is cumbersome and has low production efficiency.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0007] A sealing device for producing double-layer vacuum glass includes a main body, a door panel rotatably connected to one side of the main body for sealing the main body, a vacuum pump mounted on the main body for evacuating the interior of the main body, a pusher and a sealing platform respectively mounted on the top and bottom inner walls of the main body, an upper heating plate mounted on the output end of the pusher and a lower heating plate mounted on the top of the sealing platform and corresponding to the upper heating plate. An electric heating pump is installed inside the sealing platform. The device also includes a pushing mechanism and a cleaning mechanism.

[0008] The pushing mechanism includes a square frame mounted on top of the sealing platform and surrounding the lower heating plate, a screw rotatably mounted between the front and rear plates of the square frame and close to the side plate, a drive unit mounted on the square frame for driving the screw to rotate, a sliding column mounted between the front and rear plates of the square frame and opposite and parallel to the screw, and a U-shaped sliding plate that is threadedly engaged with the screw and slidably engaged with the sliding column, respectively. The cleaning mechanism is located on the side of the U-shaped sliding plate close to the inside of the device body and is slidably engaged with the square frame.

[0009] This invention uses a drive mechanism to rotate a screw around a square frame. The screw drives a U-shaped sliding plate to slide along a sliding post and move the U-shaped sliding plate along the outside of the device body. When the U-shaped sliding plate moves outside the device body, the operator places the upper and lower glass layers on top of each other on the U-shaped sliding plate. The drive mechanism then drives the screw to rotate in the opposite direction, causing the screw to slide along the sliding post and move the U-shaped sliding plate along the inside of the device body. When the overlapping upper and lower glass layers move to the lower heating plate, the drive mechanism is turned off, facilitating the placement of the double-layer vacuum glass. Compared with existing placement methods, this method saves manpower and improves production efficiency. It also reduces the handling of the upper and lower glass layers and minimizes the accumulation of dust and other impurities on the glass surface.

[0010] Furthermore, the aforementioned pushing mechanism also includes boxes respectively located at the top four corners of the U-shaped slide plate, and sliders slidably disposed within the boxes. The tops of the two boxes near the inner side of the device body are threadedly connected to threaded rods, and the threaded rods are threadedly connected to the corresponding sliders.

[0011] The side walls of adjacent boxes are provided with strip-shaped openings. Adjacent sliders are connected by connecting plates parallel to the screw. All sliders are provided with telescopic triangle plates on the side near the center of the square frame. The telescopic triangle plates pass through the strip-shaped openings of the boxes and extend to the outside. All telescopic triangle plates are located on the same plane. A gear is provided at the top of the threaded rod. Racks that mesh with the gears are provided on both sides of the top of the square frame.

[0012] Furthermore, the two side plates of the aforementioned square frame are symmetrically provided with through slots;

[0013] The cleaning mechanism includes two brackets respectively mounted on the U-shaped slide plate and slidably engaged with the two through slots, a through-hole column rotatably connected between the two brackets, a motor mounted on one bracket for driving the through-hole column to rotate, and several brush plates evenly arranged on the outer wall of the through-hole column and along the length of the through-hole column. The two brackets are located at both ends of the U-shaped slide plate and close to the inner side of the main body of the device.

[0014] Furthermore, the cleaning mechanism also includes a dust collection component disposed on the outside of another bracket and connected to the through-hole column via a pipe. The end of the pipe away from the dust collection component is rotatably engaged with the through-hole column, and a number of suction holes are arranged on the through-hole column.

[0015] Furthermore, the cleaning mechanism also includes an elastic telescopic rod disposed on the U-shaped slide plate and adjacent to the bracket, a semi-circular rod disposed at the top of the telescopic end of the elastic telescopic rod, an L-shaped striking rod disposed on the side wall of the semi-circular rod away from the bracket, and a cam disposed on the outer wall of the through-hole column and corresponding to the semi-circular rod, wherein the end of the L-shaped striking rod away from the semi-circular rod contacts the outer wall of the through-hole column.

[0016] Furthermore, a protrusion is fixed to the outside of the cam, and a semi-circular protrusion is fixed to the bottom of the semi-circular rod. The semi-circular protrusion of the semi-circular rod is located on the movement trajectory of the protrusion of the cam.

[0017] Furthermore, it also includes an anti-adhesion mechanism located below the U-shaped sliding plate;

[0018] The anti-adhesion mechanism includes a rotating rod and an arc plate respectively disposed between the two side plates of the square frame and near the front plate, several fan blades evenly disposed on the outer wall of the rotating rod and arranged along the length of the rotating rod, and an abutting wheel disposed on the outer wall of the end of the rotating rod. The rotating rod is located on the inner side of the arc of the arc plate, and the rotating rod is rotatably engaged with the two side plates of the square frame. The abutting wheel contacts the bottom of the U-shaped sliding plate.

[0019] Furthermore, the aforementioned anti-adhesion mechanism also includes a semi-circular block wheel disposed on the outer wall of the rotating rod and adjacent to the abutment wheel, an elastic telescopic strip disposed on the front side of the arc plate and corresponding to the semi-circular block wheel, and an abutment plate disposed on the telescopic end of the elastic telescopic strip and located below the semi-circular block wheel, wherein the telescopic end of the elastic telescopic strip contacts the bottom of the U-shaped sliding plate.

[0020] Furthermore, a semi-circular block is fixed to the outside of the aforementioned semi-circular block wheel, and the top side of the contact plate is located on the movement trajectory of the semi-circular block on the semi-circular block wheel.

[0021] The present invention also provides a sealing process for the production of double-layer vacuum glass, comprising the following steps:

[0022] S1. Open the door panel, and drive the screw to rotate around the square frame through the drive component. The screw further drives the U-shaped slide plate to slide along the slide column and make the U-shaped slide plate slide towards the opening of the main body of the device until the U-shaped slide plate moves out of the main body of the device.

[0023] S2. Place the upper and lower glass layers overlapping on the U-shaped sliding plate. The drive unit drives the screw to rotate in the opposite direction. The screw further drives the U-shaped sliding plate to slide along the sliding column and move the U-shaped sliding plate into the interior of the device body until the overlapping upper and lower glass layers move directly above the lower heating plate.

[0024] S3. After the upper and lower glass layers are placed, start the electric heating pump inside the sealing platform to heat the upper and lower heating plates.

[0025] S4. Next, start the pusher. The telescopic end of the pusher pushes the upper heating plate downward. The upper and lower heating plates heat and press the upper and lower glass layers together, thereby achieving the sealing operation of the upper and lower glass layers.

[0026] The present invention has the following beneficial effects:

[0027] 1. This invention utilizes the cooperation of a screw, U-shaped slide plate, sliding column, main body, and driving component in the pushing mechanism to move the overlapping upper and lower glass layers onto the lower heating plate. This facilitates the placement of the upper and lower glass layers, thereby avoiding the cumbersome manual handling of the upper and lower glass layers. It also reduces the amount of dust, fingerprints, and other impurities adhering to the glass surface, thus ensuring the quality of the glass seal and production efficiency.

[0028] 2. In the sealing device for double-layer glass production of the present invention, when there is a need for separate placement and processing of the upper and lower glass layers, after the U-shaped sliding plate moves out of the main body of the device, the lower glass layer is placed on the U-shaped sliding plate. The lower glass layer moves to the lower heating plate via the U-shaped sliding plate. Then, the screw drives the U-shaped sliding plate to move out of the main body of the device. At this time, the upper glass layer is placed at the telescopic end of the telescopic triangle plate. The U-shaped sliding plate is driven to enter the interior of the main body of the device again. The U-shaped sliding plate drives the box, the threaded rod, and the slider to move synchronously. The telescopic triangle plate drives the upper glass layer to the position of the upper heating plate. During the sliding of the U-shaped sliding plate along the sliding column, the gear and the rack mesh and drive the gear to rotate. The gear drives the threaded rod to rotate. The threaded rod drives the slider to move downward along the interior of the box, and finally the slider drives the telescopic triangle plate to move downward. When the telescopic triangle plate moves to the edge of the lower glass layer, the edge of the lower glass layer abuts against the telescopic end of the telescopic triangle plate and causes the telescopic end to retract. At this time, the telescopic triangle plate will place the upper glass layer in the position of the lower glass layer. Thus, the device can meet the processing needs of separate placement of the upper and lower glass layers, further improving the work efficiency of the workers.

[0029] 3. Through the cleaning mechanism of this invention, when the lower glass is placed alone on the lower heating plate, as the screw drives the U-shaped sliding plate to move out of the main body of the device, the U-shaped sliding plate drives the through-hole column to move out of the main body of the device simultaneously through the bracket. The through-hole column is driven by the motor to rotate, and the through-hole column drives the brush plate to rotate. When the brush plate passes over the upper surface of the lower glass, the brush plate will clean the upper surface of the lower glass. At the same time, the dust collection component is activated. The dust collection component extracts air from the inside of the through-hole column through the pipe. The through hole of the through-hole column generates suction force, and the through hole of the through-hole column will suck the dust and impurities swept up by the brush plate into the through-hole column. Then the dust and impurities enter the dust collection component through the pipe for collection, thereby avoiding the problem that dust and impurities adhere to the upper surface of the lower glass, which would prevent the sealant from being fully filled or adhered to the glass gap, thus reducing the sealing quality of the double-glazed glass. Simultaneously, the through-hole column, cam, semi-circular rod, and elastic telescopic rod work together to drive the L-shaped striking rod to strike the through-hole column. The through-hole column vibrates, causing the brush plate to vibrate. When the brush plate cleans the upper surface of the lower glass, it shakes off the dust and impurities attached to it. At the same time, the suction holes on the through-hole column draw the shaken-off dust and impurities into the dust collection component, thus preventing dust and impurities from adhering to the brush plate and causing secondary pollution to the lower glass.

[0030] 4. This invention, through the setting of an anti-adhesion mechanism, when the upper glass is moved into the main body of the device via the U-shaped sliding plate, under the action of friction between the U-shaped sliding plate and the abutment wheel, the U-shaped sliding plate drives the abutment wheel to rotate, the abutment wheel drives the rotating rod to rotate, the rotating rod drives the fan blade to rotate, and the fan blade generates airflow. Under the guidance of the arc plate, the arc plate guides the airflow generated by the fan blade upwards. The airflow blows away dust and other impurities on the lower surface of the upper glass. Since the arc plate and the rotating rod are both located near the front panel of the square frame, the arc plate and the rotating rod are closer to the door panel, so that the airflow generated by the fan blade can blow the dust on the lower surface of the upper glass to the outside, which can eliminate dust or impurities on the upper glass. When the U-shaped sliding plate moves into the main body of the device, the cleaning mechanism will also further clean the upper surface of the lower glass, thereby improving the appearance and quality of the double-glazed glass.

[0031] 5. In this invention, the rotating rod, semi-circular block wheel, and contact plate work together to drive the extension end of the elastic telescopic strip to strike the bottom surface of the U-shaped slide plate, causing the U-shaped slide plate to vibrate. The vibration of the U-shaped slide plate can prevent the U-shaped slide plate from getting stuck during operation. When the U-shaped slide plate gets stuck, appropriate vibration helps to restore the normal operation of the U-shaped slide plate. Attached Figure Description

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0042] Example 1:

[0043] like Figures 1 to 4As shown, an embodiment of the present invention provides a sealing device for the production of double-layer vacuum glass, including a device body 1 and a door panel 2 rotatably connected to one side of the device body 1 for sealing the device body 1. In this embodiment, there are two door panels 2, which are hinged to both sides of the device body 1. Sealing strips for sealing the device body 1 are provided on the four sides of the door panel 2. In other embodiments of the present invention, there may be only one door panel 2. A vacuum pump 3 for evacuating the interior of the device body 1 is provided on the device body 1. The vacuum pump 3 is fixed to the top of the device body 1 and communicates with the interior of the device body 1 through a pipe. A pusher 4 and a sealing platform 5 are respectively provided on the top inner wall and bottom inner wall of the device body 1. An upper heating plate 6 is connected to the output end of the pusher 4, wherein the pusher 4 is an electric push rod. A lower heating plate 7 corresponding to the upper heating plate 6 is provided on the top of the sealing platform 5, and an electric heating pump is provided inside the sealing platform 5.

[0044] It also includes a pushing mechanism 8, which comprises a square frame 81, a screw 82, a driving component 83, a sliding column 84, and a U-shaped sliding plate 85. The square frame 81 is mounted on top of the sealing platform 5 and surrounds the lower heating plate 7. The square frame 81 includes a front plate and a rear plate arranged opposite each other, as well as two left and right side plates arranged opposite each other. The rear plate is close to the rear side of the main body 1, and the front plate is close to the side of the door panel 2. The screw 82 is rotatably disposed between the front and rear plates of the square frame 81 and near the side plates. The driving component 83 is disposed on the square frame 81 and is used for driving. The screw 82 rotates, and mounting holes for mounting the screw 82 are respectively opened on the front plate and the rear plate of the square frame 81. The drive component 83 is fixed to the front plate or the rear plate by screws. The output end of the drive component 83 passes through the mounting hole and is connected to the screw 82. The sliding column 84 is set between the front plate and the rear plate of the square frame 81 and is opposite to and parallel to the screw 82. The U-shaped sliding plate 85 is threaded with the screw 82 and slidably engaged with the sliding column 84. The U-shaped sliding plate 85 is located above the front plate of the square frame 81, and the outer side of the U-shaped sliding plate 85 is in contact with the inner side wall of the square frame 81. The drive unit 83 uses a forward and reverse motor. When the forward and reverse motor drives the screw 82 to rotate, the screw 82 will drive the U-shaped slide plate 85 to move along the slide column 84, so that it can move in and out of the main body 1 of the device. This allows the U-shaped slide plate 85 to move into the main body 1 of the device and move the overlapping upper and lower glass layers to the lower heating plate 7. This avoids the problem of manually handling the upper and lower glass layers, which is cumbersome and can easily cause dust and other impurities to remain on the glass surface, affecting the glass sealing effect. This ensures the quality of the glass sealing and production efficiency.

[0045] like Figure 4 and Figure 5As shown, the pushing mechanism 8 also includes boxes 86 respectively located at the top four corners of the U-shaped slide plate 85, and sliders 87 slidably disposed within the boxes 86. The boxes 86 have axial holes that match the sliders 87. The tops of the two boxes 86 closest to the inner side of the device body 1 are threadedly connected to threaded rods 88, which are threadedly connected to the corresponding sliders 87. The sliders 87 have axially oriented threaded through holes that threadedly engage with the threaded rods 88, thus achieving a threaded connection. The side walls of adjacent boxes 86 are each provided with a slotted opening, and adjacent sliders 87... A connecting plate 89 parallel to the screw 82 is connected between them. Due to the strip opening on the side wall of the adjacent box 86, the side wall of the adjacent slider 87 is exposed, which facilitates the setting of the connecting plate 89. A telescopic triangle plate 810 is provided on the side of all sliders 87 near the center of the square frame 81. The telescopic triangle plate 810 passes through the strip opening of the box 86 and extends to the outside. All telescopic triangle plates 810 are located on the same plane. A gear 881 is provided at the top of the threaded rod 88. A rack 811 meshing with the gear 881 is provided on both sides of the top of the square frame 81. The telescopic triangle plate 810 includes a square tube fixed to the slider 87, a triangle plate that slides with the square tube, and a spring connecting the triangle plate and the inner bottom wall of the square tube. The triangle plate serves as the telescopic end of the telescopic triangle plate 810, and the end of the triangle plate away from the square tube has an inclined triangular structure.

[0046] In use, open the door panel 2, and drive the screw 82 to rotate via the drive component 83. The screw 82 drives the U-shaped slide plate 85 to move along the slide column 84 towards the outside of the device body 1. The U-shaped slide plate 85 moves out of the device body 1. At this time, the operator places the upper and lower glass layers on the U-shaped slide plate 85. The drive component 83 drives the screw 82 to rotate in the opposite direction again. The screw 82 drives the U-shaped slide plate 85 to slide along the slide column 84 and move the U-shaped slide plate 85 towards the inside of the device body 1. This moves the overlapping upper and lower glass layers onto the lower heating plate 7, thus avoiding the need for manual handling of the upper and lower glass layers, which is cumbersome.

[0047] When the upper and lower glass layers require separate placement and processing, the screw 82 is driven to rotate by the forward and reverse motor, which in turn moves the U-shaped slide plate 85 out of the main body 1 of the device. The lower glass layer is then placed on the U-shaped slide plate 85, with its two side plates located outside the lower heating plate 7. Simultaneously, the top of the U-shaped slide plate 85 is flush with the top of the lower heating plate 7. The lower glass layer moves onto the lower heating plate 7 via the U-shaped slide plate 85. Then, the screw 82 moves the U-shaped slide plate 85 out of the main body 1. At this point, the upper glass layer is placed at the telescopic end of the telescopic triangular plate 810. The U-shaped slide plate 85 is then driven back into the main body 1. The U-shaped slide plate 85 and the telescopic triangular plate 810 move the upper glass layer to the upper... When the heating plate 6 is in position, as the U-shaped sliding plate 85 slides along the sliding column 84, the gear 881 meshes with the rack 811 and drives the gear 881 to rotate. The gear 881 drives the threaded rod 88 to rotate, and the threaded rod 88 drives the slider 87 to move downward along the inside of the box 86. Ultimately, the slider 87 drives the telescopic triangle 810 to move downward. When the telescopic triangle 810 moves to the edge of the lower glass, the edge of the lower glass abuts against the telescopic end of the telescopic triangle 810 and causes the telescopic end to retract. At this time, the telescopic triangle 810 will place the upper glass on the lower glass, so that the device can meet the processing requirements of placing the upper glass and the lower glass separately, further improving the worker's work efficiency. After the upper and lower glass layers are placed, the electric heating pump and vacuum pump 3 inside the sealing platform 5 are started. The electric heating pump heats the upper heating plate 6 and the lower heating plate 7, and the vacuum pump 3 evacuates the inside of the main body 1 of the device. Then, the pusher 4 is started. The telescopic end of the pusher 4 pushes the upper heating plate 6 downward. The upper heating plate 6 and the lower heating plate 7 heat and press the upper and lower glass layers together, thereby achieving the sealing operation of the upper and lower glass layers.

[0048] like Figure 3 , Figure 6 and Figure 7 As shown, it also includes a cleaning mechanism 9, which is located on one side of the U-shaped slide plate 85 near the interior of the main body 1 and slides in cooperation with the square frame 81. The two side plates of the square frame 81 are respectively provided with through slots; the cleaning mechanism 9 is used to clean the upper surface of the lower glass when the upper and lower glass need to be placed separately.

[0049] Specifically, the cleaning mechanism 9 includes two brackets 91 respectively mounted on the U-shaped slide plate 85 and slidably engaged with two through slots. The two brackets 91 are located at both ends of the U-shaped slide plate 85 and close to the inner side of the main body 1. The two brackets 91 are slidably engaged with the through slots on the left side plate and the right side plate of the square frame 81, respectively. It also includes a through-hole column 92 rotatably connected between the two brackets 91, a motor 93 mounted on one bracket 91 for driving the through-hole column 92 to rotate, and a plurality of brush plates 94 evenly arranged on the outer wall of the through-hole column 92 and arranged along the length of the through-hole column 92. The motor 93 is fixed on the bracket 91 on the right side plate. When the lower glass is placed alone on the lower heating plate 7, the drive screw 82 of the drive component 83 moves the U-shaped slide plate 85 out of the main body 1. The U-shaped slide plate 85 moves the through hole column 92 out of the main body 1 through the bracket 91. The through hole column 92 is driven to rotate by the motor 93. The through hole column 92 drives the brush plate 94 to rotate. When the brush plate 94 passes over the upper surface of the lower glass, the brush plate 94 will clean the upper surface of the lower glass.

[0050] The cleaning mechanism 9 also includes a dust collection component 96 disposed outside another bracket 91 and connected to the through-hole post 92 via a pipe 95. The end of the pipe 95 away from the dust collection component 96 is rotatably engaged with the through-hole post 92, and a plurality of suction holes are arranged on the through-hole post 92. When the brush plate 94 cleans the upper surface of the lower glass, the dust collection component 96 is activated. The dust collection component 96 uses an existing micro-dust collection device. The dust collection component 96 extracts air from inside the through-hole post 92 through the pipe 95, generating suction at the suction holes on the through-hole post 92. The suction holes of the through-hole post 92 suck in the dust and impurities raised by the brush plate 94 into the through-hole post 92. Then, the dust and impurities enter the dust collection component 96 through the pipe 95 for collection, thereby avoiding the problem of dust and impurities adhering to the surface of the lower glass, which would prevent the sealant from being fully filled or adhering to the glass gap, thus reducing the sealing quality of the double-glazed glass.

[0051] Specifically, the cleaning mechanism 9 also includes an elastic telescopic rod 97 disposed on the U-shaped sliding plate 85 and adjacent to the bracket 91, a semi-circular rod 98 disposed on the top of the telescopic end of the elastic telescopic rod 97, an L-shaped striking rod 99 disposed on the side wall of the semi-circular rod 98 away from the bracket 91, and a cam 910 disposed on the outer wall of the through-hole column 92 and corresponding to the semi-circular rod 98. The end of the L-shaped striking rod 99 away from the semi-circular rod 98 contacts the outer wall of the through-hole column 92. The elastic telescopic rod 97 includes a telescopic outer tube, an inner rod that slides axially along the telescopic outer tube, and a return spring connected between the bottom of the inner rod and the bottom wall of the telescopic outer tube. The inner rod serves as the telescopic end of the elastic telescopic rod 97. In this embodiment, two elastic telescopic rods 97 are provided, each adjacent to one of the two brackets 91. The semi-circular rod 98, the L-shaped striking rod 99, and the cam 910 correspond one-to-one with the number of elastic telescopic rods 97. The cam 910 is located on the outer walls of both ends of the through-hole column 92. A protrusion is fixed to the outside of the cam 910, and a semi-arc protrusion is fixed to the bottom of the semi-arc rod 98. The semi-arc protrusion of the semi-arc rod 98 is located on the movement trajectory of the protrusion of the cam 910. When the through-hole post 92 rotates under the drive of the motor 93, it drives the cam 910 to rotate, which in turn pushes the semi-circular protrusion at the bottom of the semi-circular rod 98 to move upward through the protrusion of the cam 910, and the elastic telescopic rod 97 extends. When the protrusion on the cam 910 is not in contact with the semi-circular protrusion at the bottom of the semi-circular rod 98, the semi-circular rod 98 drives the L-shaped striking rod 99 to strike the through-hole post 92, causing the through-hole post 92 to vibrate. The through-hole post 92 drives the brush plate 94 to vibrate. When cleaning the upper surface of the lower glass, the brush plate 94 shakes off the dust and impurities attached to it, and at the same time, under the action of the dust suction component 96, it attracts the shaken-off dust and impurities, thereby avoiding the problem of dust and impurities adhering to the brush plate 94 and causing secondary pollution to the lower glass.

[0052] like Figure 3 and Figure 8As shown, it also includes an anti-adhesion mechanism 10, which is located below the U-shaped slide plate 85. The anti-adhesion mechanism 10 includes a rotating rod 101 and an arc plate 102 respectively disposed between the two side plates of the square frame 81 and near the front plate, a plurality of fan blades 103 evenly disposed on the outer wall of the rotating rod 101 and arranged along the length of the rotating rod 101, and an abutting wheel 104 disposed on the outer wall of the end of the rotating rod 101. The rotating rod 101 is located on the inner side of the arc of the arc plate 102, and the rotating rod 101 is rotatably engaged with the two side plates of the square frame 81. Mounting holes that engage with the end of the rotating rod 101 are opened on the two side plates of the square frame 81, thereby achieving rotation through the shaft hole engagement. The abutting wheel 104 contacts the bottom of the U-shaped slide plate 85. When the U-shaped sliding plate 85 is moved by the driving component 83 and the screw 82, the U-shaped sliding plate 85 will drive the abutment wheel 104 to rotate, which in turn drives the rotating rod 101 to rotate. In this embodiment, there are two sets of abutment wheels 104, which are fixed at both ends of the rotating rod 101 and correspond to the two side plates of the U-shaped sliding plate 85. The rotating rod 101 rotates and drives the fan blade 103 to fan. Under the action of the arc plate 102, the airflow generated by the fan blade 103 is guided upward. The airflow blows on the surface of the upper glass. By blowing air, dust or impurities on the lower surface of the upper glass can be removed, making the surface smoother and cleaner.

[0053] The anti-adhesion mechanism 10 also includes a semi-arc block wheel 105 disposed on the outer wall of the rotating rod 101 and adjacent to the abutment wheel 104, an elastic telescopic strip 106 disposed on the front side of the arc plate 102 and corresponding to the semi-arc block wheel 105, and an abutment plate 107 disposed on the telescopic end of the elastic telescopic strip 106 and located below the semi-arc block wheel 105. The telescopic end of the elastic telescopic strip 106 contacts the bottom of the U-shaped sliding plate 85. The arc plate 102 is located on the side closest to the door panel 2, which is the front side. The elastic telescopic strip 106 includes a fixed rod connected to the front side of the arc plate 102 and an outer tube that slides with the fixed rod. The outer tube serves as the telescopic end of the elastic telescopic strip 106, and the fixed rod serves as the fixed end of the elastic telescopic strip 106. Two sets of semi-arc block wheels 105, elastic telescopic strips 106, and contact plates 107 are provided. The two semi-arc block wheels 105 are located at both ends of the rotating rod 101. The fixed ends of the two elastic telescopic strips 106 are respectively fixed to the left and right front parts of the arc plate 102. The two contact plates 107 are respectively fixed to the telescopic ends of the two elastic telescopic strips 106. A semi-arc block is fixed to the outside of the semi-arc block wheel 105, and the top side of the contact plate 107 is located on the movement trajectory of the semi-arc block on the semi-arc block wheel 105. When the rotating rod 101 rotates, the semi-circular block on the semi-circular block wheel 105 will push the telescopic end of the elastic telescopic strip 106 to extend and retract through the contact plate 107, thereby striking the bottom of the U-shaped slide plate 85. The U-shaped slide plate 85 vibrates, which can prevent the U-shaped slide plate 85 from getting stuck during operation. When the U-shaped slide plate 85 gets stuck, appropriate vibration helps to restore the normal operation of the U-shaped slide plate 85.

[0054] Example 2:

[0055] An embodiment of the present invention also provides a sealing process for the production of double-layer vacuum glass, comprising the following steps:

[0056] S1. Open the door panel 2, and drive the screw 82 to rotate around the square frame 81 through the drive component 83. The screw 82 further drives the U-shaped slide plate 85 to slide along the slide column 84, and makes the U-shaped slide plate 85 slide towards the opening of the device body 1 until the U-shaped slide plate 85 moves out of the device body 1.

[0057] S2. Place the upper and lower glass layers on the U-shaped slide plate 85. The drive unit 83 drives the screw 82 to rotate in the opposite direction. The screw 82 further drives the U-shaped slide plate 85 to slide along the slide column 84 and moves the U-shaped slide plate 85 into the interior of the device body 1 until the overlapping upper and lower glass layers move directly above the lower heating plate 7.

[0058] According to step S2, when the upper and lower glass layers require separate placement and processing, the following steps are adopted:

[0059] S21. After the U-shaped slide plate 85 is removed from the main body 1, the lower glass is placed on the U-shaped slide plate 85. The lower glass will move to the lower heating plate 7 through the U-shaped slide plate 85. Then, the U-shaped slide plate 85 is driven to move out of the main body 1 through the screw 82. At this time, the upper glass is placed at the telescopic end of the telescopic triangle plate 810. The U-shaped slide plate 85 is driven to move into the main body 1 again. The U-shaped slide plate 85 drives the slider 87 to move synchronously through the box 86 and the threaded rod 88. The slider 87 drives the upper glass to move to the position of the upper heating plate 6 through the telescopic triangle plate 810.

[0060] S22. Simultaneously, the U-shaped sliding plate 85 drives the gear 881 to move synchronously through the box 86 and the threaded rod 88. The rack 811 meshes with the gear 881 and drives the gear 881 to rotate. The gear 881 drives the threaded rod 88 to rotate. The threaded rod 88 drives the slider 87 to move downward along the inside of the box 86. The slider 87 drives the telescopic triangle plate 810 to move downward. When the telescopic triangle plate 810 moves to the edge of the lower glass, the edge of the lower glass abuts against the telescopic end of the telescopic triangle plate 810 and causes the telescopic end of the telescopic triangle plate 810 to retract. At this time, the telescopic triangle plate 810 places the upper glass on the lower glass.

[0061] S3. After the upper and lower glass layers are placed, start the electric heating pump in the sealing platform 5. The electric heating pump heats the upper heating plate 6 and the lower heating plate 7.

[0062] S4. Next, start the pusher 4. The telescopic end of the pusher 4 pushes the upper heating plate 6 downward. The upper heating plate 6 and the lower heating plate 7 heat and press the upper and lower glass together, thereby achieving the sealing operation of the upper and lower glass.

[0063] In use, the screw 82, U-shaped slide plate 85, slide column 84, device body 1, and drive component 83 in the pushing mechanism 8 work together to move the overlapping upper and lower glass layers onto the lower heating plate 7, which facilitates the placement of the upper and lower glass layers and avoids the problem of cumbersome operation caused by manually moving the upper and lower glass layers. When the upper and lower glass layers require separate processing, the lower glass layer can be placed on the lower heating plate 7 in stages via the pushing mechanism 8. After the lower glass layer is placed on the lower heating plate 7, as the screw 82 moves the U-shaped sliding plate 85 out of the main body 1, the brush plate 94 in the cleaning mechanism 9 cleans the upper surface of the lower glass layer. At the same time, the dust collection component 96 is activated. The dust collection component 96 sucks the dust and impurities swept up by the brush plate 94 into the through-hole column 92 through the pipe 95, and then into the dust collection component 96 for collection. When the through-hole column 92 rotates, it drives the cam 910 to rotate. The protrusion of the cam 910 pushes the semi-arc protrusion of the semi-arc rod 98 to rotate. The semi-circular rod 98 moves upward, causing the telescopic end of the elastic telescopic rod 97 to stretch. When the protrusion of the cam 910 no longer pushes the semi-circular protrusion of the semi-circular rod 98, the semi-circular rod 98 is reset under the elastic force of the elastic telescopic rod 97. The semi-circular rod 98 causes the L-shaped striking rod 99 to strike the through-hole post 92. The through-hole post 92 causes the brush plate 94 to vibrate. When cleaning the upper surface of the lower glass, the brush plate 94 shakes off the dust and impurities attached to it. At the same time, it draws the shaken-off dust and impurities into the dust collection assembly 96 through the suction hole on the through-hole post 92, thereby avoiding the problem of dust and impurities adhering to the brush plate 94 and causing secondary pollution to the lower glass.

[0064] The upper glass is placed at the telescopic end of the telescopic triangle plate 810, and the upper glass is moved into the main body 1 of the device via the U-shaped sliding plate 85. Under the friction between the U-shaped sliding plate 85 and the abutment wheel 104, the U-shaped sliding plate 85 drives the abutment wheel 104 to rotate. The abutment wheel 104 drives the rotating rod 101 to rotate. The rotating rod 101 drives the fan blade 103 to rotate. The fan blade 103 generates airflow. Under the guidance of the arc plate 102, the airflow blows on the lower surface of the upper glass. By blowing air, dust or impurities on the upper glass can be removed, making its surface smoother and cleaner. At the same time, when the U-shaped sliding plate 85 moves into the main body 1 of the device, the cleaning mechanism 9 will further clean the upper surface of the lower glass, thereby improving the appearance and quality of the double-glazed glass.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
