Description

Technical Field

[0001] This invention relates to a glass heating device, and more particularly to a glass heating plate electrode coating device. Background Technology

[0002] The glass electric heating plate is an innovation that combines the light transmission and insulation properties of traditional glass with conductive heating technology. Its core lies in using an electric current to make the glass heat up. Silver paste electrodes are coated on both sides of the glass surface, and a transparent conductive film is coated between the silver paste electrodes. After energizing the electrodes on both sides of the film, the glass plate heats up as a whole. There are two existing methods for coating the silver electrodes: screen printing and aerosol spraying. In comparison, screen printing is more suitable for mass production, while aerosol spraying is more suitable for fine processing.

[0003] In the process of aerosol spraying, the existing technology directly uses vacuum adsorption to fix the glass. By setting an adsorption structure at the bottom of the glass, the glass is fixed in place, and then the top is sprayed evenly through the spray head. However, this spraying method requires a very high stability of the platform. Since aerosol spraying is a fine repair of the local electrode, if the glass is not fixed stably, the silver paste layer in that area will be too thin or even leak through. This will result in unstable current and uneven heat conduction during use. Furthermore, if the platform is tilted, the silver paste will flow through the glass edge to the back during spraying or printing. After sintering, it will form a conductive path, causing the entire glass to be scrapped.

[0004] Therefore, this invention aims to provide a glass heating plate electrode coating device that can clean the adsorption end and the adsorbed end of the adsorption component when the glass is fixed on the adsorption platform, ensuring the stability of the adsorption position, and can directly adjust the position of the adsorption component, thereby ensuring the stability and balance of the glass. Summary of the Invention

[0005] This invention provides a glass heating plate electrode coating device, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: A glass heating plate electrode coating device, comprising: The coating cabinet is divided into several coating chambers by partitions, and each coating chamber is equipped with a spraying mechanism at its top. The continuous conveying structure has a transition conveying section in the middle of each coating chamber, and the front and rear ends of the transition conveying section are respectively connected to a front conveyor belt and a rear conveyor belt. The self-cleaning adsorption platform includes a vacuum adsorption frame that can be raised and lowered and installed on a partition. The top of the vacuum adsorption frame is connected to a suction cup, and the inner side of the vacuum adsorption frame is provided with a suction pipe that communicates with a negative pressure device. A double-layer cleaning component is provided adjacent to the suction pipe, and the bottom of the double-layer cleaning component is connected to the pipe assembly. When the glass is transported to the transition conveying section, the vacuum adsorption frame rises and the suction cup is first spaced apart from the glass, so that the double-layer cleaning component cleans the inner side wall of the top edge of the suction cup and the lower surface of the glass. After the double-layer cleaning component has finished cleaning, it retracts into the vacuum adsorption frame, so that the vacuum adsorption frame rises again to lift the glass and then uses the suction pipe to draw negative pressure on the suction cup to fix the glass. The platform positioning structure includes a double-position groove on the outer side of the vacuum adsorption rack. The platform positioning structure includes a positioning component disposed on the inner side wall of the coating cabinet. A double-position mating component is disposed on the positioning component. When the vacuum adsorption rack rises for the first time, the double-position mating component and the double-position groove are positioned for the first time. When the vacuum adsorption rack rises for the second time, the double-position mating component and the double-position groove are positioned for the second time.

[0007] As a further improvement, the vacuum adsorption frame includes a push cylinder disposed on a partition, the top of which is connected to a vacuum sealing cylinder, the vacuum sealing cylinder being hollow inside.

[0008] As a further improvement, the suction tube includes a hard flow section disposed inside the vacuum-sealed cylinder, and the portion of the hard flow section extending to the outside of the vacuum-sealed cylinder is a soft flow section.

[0009] As a further improvement, the double-layer cleaning component includes an internal frame disposed inside the vacuum suction frame, a spiral seat disposed on the internal frame, a top pressure spring connected to the top of the spiral seat, a lower cleaning frame disposed at the upper end of the top pressure spring, and an upper cleaning frame connected to the upper end of the lower cleaning frame.

[0010] As a further improvement, the lower cleaning frame has the same structure as the upper cleaning frame, and the ratio of the lower cleaning frame to the upper cleaning frame is 1:1.5. The lower cleaning frame includes a central pipe that communicates with the pipe assembly. A fixed frame extends outward from the top of the central pipe, and an outer cleaning frame is movably arranged on the fixed frame at a position away from the central pipe.

[0011] As a further improvement, the piping assembly includes a downpipe connected to a double-layer cleaning element, the downpipe being connected to a positive pressure pipe and a negative pressure pipe respectively.

[0012] As a further improvement, the positioning component includes a positioning seat that contacts the inner wall of the coating cabinet. A first positioning cylinder and a second positioning cylinder are respectively installed on the positioning seat, and a double-positioning fitting is connected to the output end of the first positioning cylinder and the second positioning cylinder.

[0013] As a further improvement, the dual-position slot includes an outer receiving slot formed on the outside of the vacuum adsorption frame, and an inner receiving slot is recessed along the inner side of the vacuum adsorption frame. Both the outer receiving slot and the inner receiving slot are elongated slots.

[0014] As a further improvement, a positioning electrode is provided at the top of the content receiving tank, and positioning sensors are provided at the top of the outer receiving tank and the bottom of the content receiving tank.

[0015] As a further improvement, the dual-position mating component includes a first connecting post and a second connecting post respectively disposed on the first positioning cylinder and the second positioning cylinder. The length of the second connecting post is longer than that of the first connecting post. When the first connecting post and the second connecting post are in contact with the two positioning sensors and the positioning electrode respectively, the glass is in a horizontal state.

[0016] The beneficial effects of this invention are: Existing vacuum adsorption platforms fix glass using suction cup assemblies. However, each operation requires checking for powder particles on the suction cups and the bottom surface of the glass. If any suction cup in a multi-platform system contains particles, leakage can easily occur during vacuuming, leading to an imbalance in the glass position, resulting in an excessively thin silver paste layer or even complete leakage. Therefore, this invention utilizes a self-cleaning adsorption platform that moves to the bottom of the glass via a vacuum adsorption frame. After the double-layer cleaning components contact the glass, positive pressure air is introduced through a pipe assembly, allowing the double-layer cleaning components to clean the suction cups and the bottom surface of the glass. This ensures that the contact surfaces between the suction cups and the glass are free of fingerprints, oil, or dust, and that there are no residual particles on the inner adsorption surface of the suction cups, guaranteeing the stability of the adsorption surfaces. This enhances the glass fixation effect, enabling the desired effect during electrode coating, resulting in a uniform and stable silver paste surface.

[0017] Since the vacuum adsorption rack needs to be raised and lowered, and the interior needs to be vacuumed and sealed, the vacuum sealing cylinder of the vacuum adsorption rack of the present invention is hollow inside, and a push cylinder is provided at the bottom, which can change its own height, so that the input glass can adjust its own state according to the glass entering.

[0018] During the vacuuming process, the position of the vacuum suction frame changes, and a stable suction force is required inside. Therefore, in this embodiment, the inside of the suction tube is a rigid flow section, while the outside is a soft flow section. The soft flow section can adapt to the vacuum suction frame with varying heights, thereby preventing the tube from deforming.

[0019] The double-layer cleaning component is not a fixed mechanism; it needs to rotate to remove any substances that may be present on the glass and inside the suction cup. This invention uses a spiral seat on the built-in frame, which is similar to a paddle. When positive pressure air is introduced, it will rotate, causing the lower and upper cleaning frames to rotate simultaneously, achieving simultaneous cleaning of both areas. Furthermore, the top pressure spring ensures that the double-layer cleaning component can adhere to the bottom surface of the glass when it comes into contact with it, guaranteeing effective cleaning of the bottom surface.

[0020] During cleaning, the lower and upper cleaning frames need to have a large radiation area. However, since the lower and upper cleaning frames cannot exceed the coverage area of ​​the suction cup when stationary, the cleaning frame of the present invention is segmented, consisting of a fixed frame and a movable outer frame. This allows the outer frame to be extended when positive pressure air is introduced and retracted when negative pressure is formed.

[0021] The vacuum adsorption rack needs to continuously move up and down to change its position during glass feeding. However, the displacement and position of the vacuum adsorption rack are also very important. Since the position of the spraying mechanism remains constant in the longitudinal direction, if there are problems with the movement of the vacuum adsorption rack, especially since the vacuum adsorption rack in this invention has two displacements, if the movement accuracy is off, no matter how well the adsorption platform ensures the adsorption effect, the silver paste coating cannot achieve the expected effect. Therefore, this invention uses a platform positioning structure. First, a double-position groove is opened on the outside of the vacuum adsorption rack, and a double-position mating component is set at the corresponding position on the coating cabinet. The double-position mating component can engage with the double-position groove twice, thereby accurately limiting and detecting the two movements of the vacuum adsorption rack. After the double-position mating component detects that the vacuum adsorption rack has accurately reached its position after the two movements, it is determined that the vacuum adsorption rack has reached the designated position after the movement, and its longitudinal and lateral position information meets the requirements. The glass mounted on it can be kept in a horizontal state, thereby avoiding back print contamination caused by the glass tilting. Attached Figure Description

Detailed Implementation

[0029] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figures 1-5 As shown, a glass heating plate electrode coating device includes: a coating cabinet 10, the interior of which is divided into several coating chambers by a partition 11, each of which is equipped with a spraying mechanism 12 at its top; a continuous conveying structure, each of which has a transition conveying section 21 in the middle, the front end and rear end of which are respectively connected to a front conveyor belt 22 and a rear conveyor belt 23; and a self-cleaning adsorption platform 30, including a vacuum adsorption frame 31 that can be raised and lowered and mounted on the partition 11, the top of which is connected to a suction cup 32, and the inner side of which is provided with a suction pipe 33 communicating with a negative pressure device, and a double-layer cleaning component 34 adjacent to the suction pipe 33, the bottom of which is connected to a pipe assembly 35. When the glass is conveyed to the transition conveying section 21, the... The vacuum suction rack 31 rises and sets the suction cup 32 at a distance from the glass, allowing the double-layer cleaning component 34 to clean the inner wall of the top edge of the suction cup and the lower surface of the glass. After the double-layer cleaning component 34 finishes cleaning, it retracts into the vacuum suction rack 31, causing the vacuum suction rack 31 to rise a second time, lifting the glass and using the suction pipe 33 to draw negative pressure to fix the glass in place. The platform positioning structure 40 includes a double-position groove 311 on the outer side of the vacuum suction rack 31. The platform positioning structure 40 includes a positioning component 41 set on the inner wall of the coating cabinet 10. The positioning component 41 is equipped with a double-position mating component 42. When the vacuum suction rack 31 rises for the first time, the double-position mating component 42 and the double-position groove 311 perform the first positioning. When the vacuum suction rack 31 rises for the second time, the double-position mating component 42 and the double-position groove 311 perform the second positioning.

[0032] During electrode coating, the glass to be coated is placed on the front conveyor belt 22 with the side facing up. It is then fed into the transition conveyor section 21 via the front conveyor belt 22. The glass is then lifted by the self-cleaning adsorption platform 30 and sprayed out by the spraying mechanism 12. Afterward, the self-cleaning adsorption platform 30 is lowered so that the transition conveyor section 21 transports the coated glass towards the rear conveyor belt 23.

[0033] Existing vacuum adsorption platforms fix glass using suction cup assemblies. However, each time a work is performed, it is necessary to check whether there are powder particles on the suction cup 32 and the bottom surface of the glass. If there are particles on one of the suction cups 32 among multiple adsorption platforms, leakage is likely to occur during vacuuming, leading to an imbalance in the glass position, resulting in an excessively thin silver paste layer or even a bottom leak. Therefore, this embodiment uses a self-cleaning adsorption platform 30, which can be moved to the bottom of the glass via the vacuum adsorption frame 31. After the double-layer cleaning component 34 contacts the glass, positive pressure air is introduced through the pipe assembly 35, allowing the double-layer cleaning component 34 to clean the suction cup 32 and the bottom surface of the glass. This ensures that there are no fingerprints, oil, or dust on the contact surface of the suction cup 32 when it contacts the glass, and that there are no residual particles on the inner adsorption surface of the suction cup 32, ensuring the stability between the adsorption surfaces. This enhances the fixation effect of the glass, thereby achieving the expected effect during electrode coating, resulting in a uniform and stable silver paste surface.

[0034] Since the vacuum adsorption rack 31 needs to be raised and lowered, and the interior needs to be vacuumed and sealed, the vacuum adsorption rack 31 in this embodiment includes a push cylinder 312 disposed on the partition 11. The top of the push cylinder 312 is connected to a vacuum sealing cylinder 313. The vacuum sealing cylinder 313 is hollow inside. The vacuum adsorption rack 31 has a hollow interior and a push cylinder 312 at the bottom, which can change its own height so that the input glass can adjust its own state according to the glass entering.

[0035] During the vacuuming process, the position of the vacuum suction frame 31 changes, and a stable suction force is required inside. Therefore, the suction tube 33 in this embodiment includes a hard flow section 331 disposed inside the vacuum sealing cylinder 313. The portion of the hard flow section 331 extending to the outside of the vacuum sealing cylinder 313 is a soft flow section 332. The inside of the suction tube 33 is the hard flow section 331, while the outside is the soft flow section 332. The soft flow section 332 can adapt to the vacuum suction frame 31 with varying heights, thereby preventing deformation of the tube.

[0036] The dual-layer cleaning component 34 is not a fixed mechanism; it needs to rotate to remove any substances that may be present on the inside of the glass and suction cup 32. In this embodiment, the dual-layer cleaning component 34 includes an internal frame 341 disposed inside the vacuum suction frame 31. A spiral seat 345 is disposed on the internal frame 341, and a top pressure spring 342 is connected to the top of the spiral seat 345. A lower cleaning frame 343 is disposed above the top pressure spring 342, and an upper cleaning frame 34 is connected to the upper end of the lower cleaning frame 343. 4. By setting a spiral seat 345 on the built-in frame 341, the spiral seat 345 is set like a paddle. When positive pressure air is introduced, it will drive it to rotate, so that the lower cleaning frame 343 and the upper cleaning frame 344 rotate at the same time, realizing simultaneous cleaning of two places. The top pressure spring 342 can fit against the bottom surface of the glass when the double-layer cleaning part 34 contacts the glass, ensuring the cleaning effect of the bottom surface. The spiral seat 345 and the built-in frame 341 are in a relatively movable state, and the spiral seat 345 is movably inserted into the center of the built-in frame 341.

[0037] In this embodiment, the lower cleaning frame 343 and the upper cleaning frame 344 have the same structure, and the ratio of the lower cleaning frame 343 to the upper cleaning frame 344 is 1:1.5. Since the upper cleaning frame 344 needs to be in contact with the glass, it needs to be larger.

[0038] During cleaning, the lower cleaning frame 343 and the upper cleaning frame 344 need to have a large radiation area. However, since the lower cleaning frame 343 and the upper cleaning frame 344 cannot exceed the coverage area of ​​the suction cup 32 when stationary, the lower cleaning frame 343 in this embodiment includes a central pipe 3431 that communicates with the pipe assembly 35. A fixed frame 3432 extends outward from the top of the central pipe 3431. An outer cleaning frame 3433 is movably arranged on the fixed frame 3432 at a position away from the central pipe 3431. The cleaning frame is segmented, consisting of a fixed fixed frame 3432 and a movable outer cleaning frame 3433. This allows the outer cleaning frame 3433 to be pushed out when positive pressure air is introduced and to be retracted when negative pressure is formed. Several output holes are opened on the outer side of the outer cleaning frame 3433.

[0039] The pipe assembly 35 is not a single-channel assembly. In this embodiment, the pipe assembly 35 needs to provide both positive and negative pressure. Specifically, the pipe assembly 35 includes a lower pipe 351 connected to the double-layer cleaning component 34. The lower pipe 351 is connected to a positive pressure pipe 352 and a negative pressure pipe 353, which can respectively input positive pressure air and generate negative pressure. It is used in a single chamber and does not affect the vacuuming action inside the vacuum adsorption frame 31. It should be emphasized that the lower pipe 351 is internally rotatably connected to the screw seat 345. The rotation of the screw seat 345 does not affect the positive pressure air and negative pressure of the lower pipe 351.

[0040] The vacuum adsorption rack 31 needs to continuously move up and down to change its position during glass feeding. However, the displacement and position of the vacuum adsorption rack 31 are also very important. Since the position of the spraying mechanism 12 remains unchanged in the longitudinal direction, if there is a problem with the movement of the vacuum adsorption rack 31, especially since the vacuum adsorption rack 31 in this invention has two displacements, if the movement accuracy is deviated, no matter how the adsorption platform ensures the adsorption effect, the silver paste coating cannot achieve the expected effect. Therefore, this invention uses a platform positioning structure 40, which first opens a double-position groove 311 on the outside of the vacuum adsorption rack 31, and sets a double-position mating part 42 at the corresponding position of the coating cabinet 10, so that the double-position mating part 42 can cooperate with the double-position groove 311 twice, thereby accurately limiting and detecting the two movements of the vacuum adsorption rack 31. After the double-position mating part 42 detects that the vacuum adsorption rack 31 has accurately reached its position after two movements, it is determined that the vacuum adsorption rack 31 has reached the designated position after the movement, and its longitudinal and transverse position information meets the requirements. The glass mounted on it can be kept in a horizontal state, thereby avoiding the back print contamination phenomenon caused by the glass tilting.

[0041] When the positioning component 41 engages with the double-position cooperating component 42, since the double-position cooperating component 42 is a double-position action, the positioning component 41 in this embodiment includes a positioning seat 411 that is connected to the inner wall of the coating cabinet 10. The positioning seat 411 is provided with a first positioning cylinder 412 and a second positioning cylinder 413 respectively. The output ends of the first positioning cylinder 412 and the second positioning cylinder 413 are connected to the double-position cooperating component 42, so that two-stage limit detection can be achieved by two-stage push-out.

[0042] In order to cooperate with the dual-position mating component 42, the dual-position groove 311 includes an outer receiving groove 3111 formed on the outside of the vacuum adsorption frame 31. The outer receiving groove 3111 is recessed along the inner side of the vacuum adsorption frame 31 and has a content receiving groove 3112. Both the outer receiving groove 3111 and the content receiving groove 3112 are elongated grooves. The top of the content receiving groove 3112 is provided with a positioning electrode 3113. The top of the outer receiving groove 3111 and the bottom of the content receiving groove 3112 are both provided with positioning sensors 3114. By setting multiple point detection, multi-groove detection and limiting are realized.

[0043] Correspondingly, the dual-position mating component 42 includes a first connecting post 421 and a second connecting post 422 respectively disposed on the first positioning cylinder 412 and the second positioning cylinder 413. The length of the second connecting post 422 is longer than that of the first connecting post 421. When the first connecting post 421 and the second connecting post 422 are in contact with the two positioning sensors 3114 and the positioning electrode 3113 respectively, the glass is in a horizontal state. By utilizing the cooperation between the post and the groove, the glass can be stably coated with electrodes.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
