[0002] Tempered glass is a type of safety glass whose strength is increased through controlled heat treatment or chemical treatment of ordinary glass. With the popularization of tempered glass, people have developed coated tempered glass in pursuit of aesthetically pleasing, energy-saving and environmentally friendly tempered glass. Tempered glass coating involves coating one or more layers of metal, alloy or metal compound film onto the glass surface under compressive stress to change the optical properties of the glass and meet certain specific requirements.

[0003] Currently, existing technologies generally use coating machines to coat glass. However, existing coating machines can usually only coat one side of the glass, and then the glass needs to be manually flipped over for coating on the other side. This results in low production efficiency. In addition, fingerprints are easily left on the surface of tempered glass when it is manually flipped over. Therefore, there is an urgent need for a coating machine for tempered glass to solve the above problems. Utility Model Content

[0007] The present invention is further configured such that: the conveying unit has three units that are equidistantly fixed on the upper surface of the base, the three conveying units arranged at intervals form two mating gaps, and the drive shaft has two fixed discs corresponding to the mating gaps.

[0008] The present invention is further configured such that: a first protective pad is provided on the outer circumferential surface of the fixed plate between every two corresponding flip arms, and multiple second protective pads are provided on the opposite sides of the two corresponding flip arms, and the second protective pads near the outer end of the flip arms are designed with an edge-wrapping.

[0009] The present invention is further configured such that both the first protective pad and the second protective pad are made of elastic rubber.

[0010] The present invention is further configured such that: the outer surface of the first protective pad or the second protective pad is formed with a receiving recess, and a fastening hole adapted to the external fastener is opened at the bottom of the receiving recess; threaded holes are opened on the outer peripheral surface of the fixed plate at the assembly point of the first protective pad and on the inner side of the flip arm at the assembly point of the second protective pad.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown in the figure, a coating machine for tempered glass according to an embodiment of the present invention includes two coating units 1 spaced apart. The coating unit 1 is equipped with a coating device 10. A flipping mechanism 2 is provided between the two coating units 1. The flipping mechanism 2 includes a base 20 and a plurality of conveying units 3 spaced apart on the base 20. Two fixed frames 4 are provided at the front and rear ends of the base 20 respectively. A drive shaft 40 is rotatably provided between the two fixed frames 4 and is connected to an external power source. A fixed plate 41 is provided at the center of each pair of adjacent conveying units 3. A plurality of pairs of corresponding flipping arms 42 are provided at equal intervals on the outer circumference of the fixed plate 41. The glass material is rotated and flipped by driving the rotation of each flipping arm 42.

[0020] In use, the equipment has two spaced-apart coating units 1. Each coating unit 1 contains a coating device 10 and a conveying roller. The operator feeds the glass material to be coated into the coating unit 1 on the left. The conveying roller of the coating unit 1 transports the glass material to below the coating device 10. After the coating device 10 coats the glass, it continues to be transported to the right and enters the flipping mechanism 2. The flipping mechanism 2 flips the glass material and then the glass material continues to be transported to the right. The glass material then enters the other coating unit 1 on the right for coating on the other side, thus completing the double-sided coating of the glass material. The structure and working principle of the coating unit 1 and the coating device 10 are existing technologies and will not be described in detail here.

[0021] The working principle of the flipping mechanism 2 is as follows: the glass material after being coated by the first coating unit 1 on the left is transported to the flipping mechanism 2. Each conveying unit 3 of the flipping mechanism 2 continues to transport the glass material to the right. The glass material moves to the right until it enters one of the flipping arms 42. A receiving area is formed between the two flipping arms 42 to accommodate and drive the glass material to flip. At this time, the external drive source (servo motor) controls the drive shaft 40 to rotate. The drive shaft 40 drives the fixed plate 41 and each flipping arm 42 to rotate. The rotation of each flipping arm 42 drives the glass material to rotate and flip. After the flipping is completed, the conveying unit 3 drives the glass material to move to the right and enter the second coating unit 1 on the right for coating on the other side.

[0022] This invention achieves double-sided coating of glass materials through two coating units 1 and a flipping mechanism 2, eliminating the need for manual flipping during coating, saving time and effort, improving coating efficiency, enhancing the ease of operation for workers, and reducing workload; at the same time, it avoids fingerprints from workers adhering to the tempered glass surface due to manual flipping, making the tempered glass cleaner during coating.

[0023] The conveying unit 3 includes two symmetrically arranged fixed plates 30. Two rollers 31 are connected to both ends of the two fixed plates 30. A conveyor belt 32 is wound around the outer ring of the two rollers 31. Two mounting plates 33 are provided on the opposite side of the two fixed plates 30 and are fixedly connected to the base 20 through the mounting plates 33.

[0024] In use, one of the rollers 31 of each conveying unit 3 is connected to an external power source (servo motor) for drive. During operation, the external power source drives each corresponding roller 31 to rotate synchronously. The rotation of the roller 31 drives each conveyor belt 32 to work synchronously through the cooperation between the roller 31 and another roller 31, so as to realize the conveying of glass material. Each conveying unit 3 is installed and fixed to the base 20 through the mounting plate 33.

[0025] The conveying unit 3 has three units that are equidistantly fixed to the upper surface of the base 20. The three conveying units 3 are spaced apart to form two mating gaps, and the drive shaft 40 has two fixed discs 41 that correspond to the mating gaps.

[0026] In use, this utility model uses three conveying units 3 in conjunction with two fixed disks 41 and each set of flipping arms 42 on the outside of the fixed disks 41 to efficiently and stably transport and flip glass materials.

[0027] A first protective pad 43 is provided on the outer peripheral surface of the fixed plate 41 between each pair of corresponding flip arms 42. Multiple second protective pads 44 are provided on the opposite sides of each pair of corresponding flip arms 42. The second protective pads 44 near the outer end of the flip arms 42 have an edge-wrapping design. Both the first protective pad 43 and the second protective pad 44 are made of elastic rubber. The outer surface of the first protective pad 43 or the second protective pad 44 is formed with a receiving recess 45. The bottom of the receiving recess 45 is provided with a fastening hole 46 that is compatible with external fasteners. Threaded holes 47 are provided on the outer peripheral surface of the fixed plate 41 at the assembly point of the first protective pad 43 and on the inner side of the flip arm 42 at the assembly point of the second protective pad 44.

[0028] When in use, the protective pads ensure that the glass material makes soft contact with the flipping arm 42, effectively protecting the glass material and preventing it from breaking during the flipping process. The second protective pad 44, which is close to the outer end of the flipping arm 42, has a wrapping design to prevent the glass from colliding with the outer end of the flipping arm 42 during the flipping process.

[0029] The first protective pad 43 and the second protective pad 44 are detachably connected to the fixed plate 41 and the rotating arm 42, which facilitates daily maintenance and replacement. Specifically, when installing the first protective pad 43 or the second protective pad 44, the external fastener (bolt or screw) is passed through the fastening hole 46 formed in the first protective pad 43 or the second protective pad 44, and then the fastener is tightened with the threaded hole 47 on the outside of the fixed plate 41 or the inside of the rotating arm 42 to complete the installation and fixing of the first protective pad 43 or the second protective pad 44. The recess is used to accommodate the fastener.

[0030] Four dust collection chambers 5 are arranged in pairs on the front and back sides of the base 20. Each dust collection chamber 5 includes a shell and an inner cavity. A gas connector 50 that communicates with the inner cavity is fixed on one side of the dust collection chamber 5 and is connected to an external dust collection unit. Several dust collection ports 51 are opened at one end of the dust collection chamber 5 near the inner side of the base 20.

[0031] When in use, the external dust collection unit (existing technology) is activated. The dust collection unit sucks the dust into the dust collection chamber 5 through the gas connector 50 and the dust collection port 51 and guides it to the dust collection point. When the flipping mechanism 2 is working, each dust collection unit sucks the dust in the air to prevent the dust from adhering to the outer surface of the glass material during the flipping process and affecting the coating effect.

[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. Several sensors are installed at corresponding locations on the coating unit and the flipping mechanism (the sensors are directly selected from conventional models available on the market and are not shown in the figure). Each sensor is electrically connected to the external main controller to control each electrical component to perform actions according to the preset process, ensuring the smooth operation and stability of the equipment.
