Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a glass support device for glass surface spraying. Background Technology

[0002] Glass surface spraying is a key step in the field of glass deep processing, widely used in high-end manufacturing sectors such as building curtain walls, automotive glass, and appliance panels. Currently, the industry's technical requirements for support devices mainly focus on two aspects: stability and adaptability. On the one hand, it needs to ensure that the glass remains absolutely fixed during high-speed spraying operations to avoid uneven coating thickness due to vibration; on the other hand, it needs to be compatible with various glass shapes, including flat, curved, and irregularly cut structures.

[0003] Currently, the support devices commonly used in the glass spraying industry mainly rely on two methods: mechanical clamps or vacuum adsorption. Mechanical clamps fix the glass edges with rigid jaws. Although the structure is simple, it has obvious limitations. When dealing with curved or irregularly shaped glass, the clamps cannot fit the curved surface of the glass perfectly, which can easily cause stress concentration at the glass edges, leading to micro-cracks or even breakage. Although vacuum adsorption technology can adapt to some curved surfaces, it has insufficient adsorption force on rough frosted glass surfaces, which can easily lead to air leakage and detachment. Therefore, a glass support device for glass surface spraying is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a glass support device for spraying on glass surfaces, in order to solve the problems mentioned in the background art. The mechanical clamps that fix the glass edges with rigid jaws have a simple structure but obvious limitations. When facing curved or irregularly shaped glass, the clamps cannot fit the curved glass surface completely, which easily causes stress concentration at the glass edge, leading to micro-cracks or even breakage. Although vacuum adsorption technology can adapt to some curved surfaces, it has insufficient adsorption force for rough frosted glass and is prone to air leakage and detachment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass support device for glass surface spraying, comprising a circular air pressure sealed chamber, a cover and a worktable, wherein the cover is detachably fitted onto the outside of the circular air pressure sealed chamber by means of a threaded connection, a support assembly is provided on the top of the cover, and an air supply assembly is provided inside the circular air pressure sealed chamber.

[0006] The support assembly includes multiple straight cylinders, a pressure sensor, and a programmable controller. The straight cylinders are evenly distributed on the top of the hatch, and the top of the hatch has several through holes that communicate with the straight cylinders. A piston is slidably connected inside the straight cylinder, and a movable rod is fixedly connected to the upper surface of the piston. The end of the movable rod away from the piston moves through the straight cylinder and is fixedly connected to a rubber block.

[0007] The gas delivery assembly includes an inflation pump, an extraction pump, and a flow equalization grid. The air outlet of the inflation pump is connected to a circular pressure-sealed chamber via an air inlet pipe, and the air inlet of the extraction pump is connected to the circular pressure-sealed chamber via an air outlet pipe.

[0008] Preferably, the outer side of the aforementioned circular pressure-sealed chamber is provided with external threads, and the inner wall of the chamber cover is provided with internal threads that are compatible with the external threads.

[0009] Preferably, a sealing ring is fixedly connected to the inner top wall of the aforementioned hatch cover. The sealing ring is deformed by pressure when the hatch cover is tightened to achieve axial sealing. The flow equalization grid is located inside the circular air pressure sealing chamber.

[0010] Preferably, the pressure sensor and the programmable controller are both fixedly installed on one side of the hatch, and the pressure sensor is electrically connected to the inflation pump through the programmable controller.

[0011] Preferably, the circular air pressure sealing chamber is fixedly embedded in the workbench, and the air pump and the air extraction pump are both fixedly installed at the bottom of the circular air pressure sealing chamber.

[0012] Preferably, the interior of the aforementioned circular pressure-sealed chamber is bolted with a filter screen, which is located above the flow equalization grid.

[0013] Preferably, the inner bottom wall of the circular air pressure sealing chamber is provided with a water outlet, and a water outlet pipe is fixedly connected to the bottom of the circular air pressure sealing chamber. The water outlet pipe is connected to the circular air pressure sealing chamber through the water outlet.

[0014] Preferably, the inner bottom wall of the aforementioned circular air pressure sealing chamber is provided with a flow guide groove, the lowest point of which is located at the water outlet.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] This invention utilizes a multi-independently controlled flexible rubber block support structure to ensure uniform force distribution on the glass surface, completely eliminating the risk of micro-cracks. Addressing the limitations of vacuum adsorption technology in adapting to curved glass, a pneumatically driven piston-rod adaptive system is employed, allowing each support point to automatically adjust its height according to the glass curvature, ensuring full-surface fit support for any curved surface. To address the issue of air leakage on rough surfaces such as frosted glass, a threaded connection in the sealed chamber, combined with a raised sealing ring design and closed-loop control via a pressure sensor, achieves a stable and reliable adsorption effect.

[0028] Example

[0029] In existing technologies, mechanical clamps fix the glass edges with rigid jaws. Although the structure is simple, it has obvious limitations. When facing curved or irregularly shaped glass, the clamps cannot fit the curved surface of the glass completely, which easily causes stress concentration at the glass edges, leading to micro-cracks or even breakage. Although vacuum adsorption technology can adapt to some curved surfaces, it has insufficient adsorption force on rough frosted glass, which is prone to air leakage and detachment.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a glass support device for glass surface spraying, comprising a circular air pressure sealing chamber 1, a cover 2, and a worktable 7. The circular air pressure sealing chamber 1 is fixedly embedded in the worktable 7, and the worktable 7 provides fixed support for the circular air pressure sealing chamber 1. The outer side of the circular air pressure sealing chamber 1 is provided with an external thread 3, and the inner sidewall of the cover 2 is provided with an internal thread 4 that matches the external thread 3. The external thread 3 and the internal thread 4 are multi-start threads with a pitch range of 2-5mm. The thread engagement length is not less than 1 / 5 of the height of the circular air pressure sealing chamber 1. The cover 2 is detachably fitted onto the outer side of the circular air pressure sealing chamber 1 through threaded engagement. The top of the cover 2 is provided with a support assembly 5, and the interior of the circular air pressure sealing chamber 1 is provided with... The gas supply assembly 6 has a water outlet 12 on the inner bottom wall of the circular air pressure sealed chamber 1. A water outlet pipe 11 is fixedly connected to the bottom of the circular air pressure sealed chamber 1. The water outlet pipe 11 is connected to the circular air pressure sealed chamber 1 through the water outlet 12. During the glass spraying process, the condensed liquid is automatically drained through the water outlet pipe 11. The inner bottom wall of the circular air pressure sealed chamber 1 is provided with a guide groove 10. The lowest point of the guide groove 10 is located at the water outlet 12. The guide groove 10 guides the condensed liquid. A sealing ring 8 is fixedly connected to the inner top wall of the cover 2. The cross-section of the sealing ring 8 is convex. When the cover 2 is tightened to the closed state, the lower surface of the sealing ring 8 forms an interference fit with the edge of the top opening of the circular air pressure sealed chamber 1 to achieve axial sealing.

[0031] The support assembly 5 includes multiple straight cylinders 51, a pressure sensor 55, and a programmable controller 56. The straight cylinders 51 are evenly distributed on the top of the hatch 2. The top of the hatch 2 has several through holes 57 that communicate with the straight cylinders 51. A piston 52 is slidably connected inside the straight cylinder 51. A piston rod 53 is fixedly connected to the upper surface of the piston 52. The end of the piston rod 53 away from the piston 52 moves through the straight cylinder 51 and is fixedly connected to a rubber block 54. The pressure sensor 55 and the programmable controller 56 are both fixedly installed on one side of the hatch 2. The pressure sensor 55 is electrically connected to the air pump 62 through the programmable controller 56. The sensing end of the pressure sensor 55 is provided with a contact. The end of the contact is embedded in the outer surface of the rubber block 54. When the pressure on the surface of the rubber block 54 exceeds the set threshold range for more than 3 seconds (to prevent accidental contact), the pressure sensor 55 drives the air pump 62 to shut down through the programmable controller 56.

[0032] The gas supply assembly 6 includes an air pump 62, an air pump 64, and a flow equalization grid 65. The air pump 62 and the air pump 64 are both fixedly installed at the bottom of the circular pressure sealing chamber 1. The circular pressure sealing chamber 1 provides fixed support for the air pump 62 and the air pump 64. The air outlet of the air pump 62 is connected to the circular pressure sealing chamber 1 through the air inlet pipe 61. The air inlet of the air pump 64 is connected to the circular pressure sealing chamber 1 through the air outlet pipe 63. The flow equalization grid 65 is located inside the circular pressure sealing chamber 1. A filter screen 9 is fixedly connected to the inside of the circular pressure sealing chamber 1 by bolts. The filter screen 9 is located above the flow equalization grid 65. The filter screen 9 is used to prevent impurities from entering the air pump 62 and the air pump 64 through the straight cylinder 51.

[0033] The working principle or structural principle is as follows: The cover 2 is screwed onto the outside of the circular pneumatic sealing chamber 1 and tightened. When the cover 2 is tightened to the closed state, the lower surface of the sealing ring 8 forms an interference fit with the edge of the top opening of the circular pneumatic sealing chamber 1, achieving axial sealing. The glass to be sprayed is placed on the workbench 7, covering the entire circular pneumatic sealing chamber 1. The air pump 62 is started, and high-pressure gas is injected into the circular pneumatic sealing chamber 1 through the air inlet pipe 61. After being evenly distributed through the flow equalization grid 65, the high-pressure gas is evenly injected into each straight cylinder 51 through the through hole 57, pushing the piston 52 inside the straight cylinder 51 upwards. Rod 53 pushes rubber block 54 upward, and multiple rubber blocks 54 push glass upward. When the pressure at rubber block 54 is greater than the threshold set by pressure sensor 55, the air pump 62 is turned off. Alternatively, when the glass moves to the designated position, the air pump 62 is turned off, and the glass is in a suspended state. The upper surface of the glass is sprayed. After the upper surface of the glass is sprayed and dried, the vacuum pump 64 is manually turned on to extract the gas from the circular air pressure sealing chamber 1. The piston 52 drives the rubber block 54 to move down to the worktable 7 through the piston rod 53, and the glass is flipped over. Similarly, the other side of the glass is sprayed.

[0034] In summary, the glass to be sprayed is placed on the workbench 7, and the air pump 62 injects high-pressure gas into the circular air pressure sealing chamber 1 through the air inlet pipe 61 and into each straight cylinder 51. The piston 52 pushes the rubber block 54 upward through the piston rod 53. Multiple rubber blocks 54 push the glass upward. When the pressure at the rubber block 54 is greater than the threshold set by the pressure sensor 55, the air pump 62 is driven to shut off. Alternatively, when the glass moves to the designated position, the air pump 62 is shut off, and the glass is in an air state, so the upper surface of the glass is sprayed. The filter screen 9 needs to be cleaned regularly, and the piston 52 and rubber block 54 need to be inspected regularly. The pressure sensor 55 is a WPAH01 manufactured by Zhengzhou Weisheng Electronic Technology Co., Ltd. The programmable controller 56 is a TX3U-14MT manufactured by Zhongshan Yueyang Tianli Electronic Technology Co., Ltd. The air pump 62 is a 370 vacuum pump manufactured by Dongguan Bohang Transmission Technology Co., Ltd. The air pump 64 is a YB5552PM manufactured by Guangdong Fuyubang Pump Valve Technology Co., Ltd. Since the structure and operating principle of this model are existing technologies, their structure and operating principle will not be described in detail here.
