Description

Technical Field

[0001] The utility model belongs to the technical field of glass coating, and relates to a substrate rack, in particular to a substrate rack suitable for a horizontal coating production line. Background Art

[0002] With the increasing demand for energy-saving new energy vehicles, low-emissivity coated glass is being widely adopted in automotive manufacturing. Due to the need to achieve lightweight vehicles, glass thickness has been gradually reduced from 3mm to 2.1mm, 1.8mm, 1.6mm, 1.2mm, and even thinner. However, the coating of ultra-thin glass places increasingly stringent requirements on transmission equipment, to the point that some roller conveyor lines are no longer sufficient for ultra-thin glass production.

[0003] In addition, the roller part of the ordinary horizontal coating production line directly contacts the glass surface, which makes it very easy for the ultra-thin glass to be scratched or have a series of quality defects such as roller marks when it is transmitted on the roller, thereby reducing the glass yield and increasing production costs.

[0004] CN114427082A discloses a substrate rack for continuous coating equipment, comprising a circulating guide rail fixedly connected to a bracket, a rack disposed inside the circulating guide rail, and a slider mechanism movably disposed on the circulating guide rail. The slider mechanism comprises side panels symmetrically arranged on either side of the circulating guide rail, the side panels being connected by a bottom plate at a lower portion, and a first motor disposed on the bottom plate for driving the slider mechanism to reciprocate along the circulating guide rail. However, the substrate rack structure provided by this invention is extremely complex, resulting in high design costs, and cannot effectively prevent quality defects that may occur when ultra-thin glass is transported on a roller conveyor.

[0005] It can be seen that how to provide a substrate rack suitable for a horizontal coating production line to effectively avoid a series of quality defects such as surface scratches or roller marks when ultra-thin glass is transmitted on a roller conveyor, improve the glass yield, and at the same time simplify the device structure and reduce design costs has become an urgent problem that technical personnel in this field need to solve.

[0047] Application Examples 1-4

[0048] This group of application examples uses the substrate racks provided in Examples 1-4 to carry the glass to be coated in a horizontal coating production line, and specifically includes the following steps:

[0049] (1) The substrate holder is placed on the surface of the conveyor roller by a manipulator and the positioning pin 2 is inserted, thereby fixing the bracket body 1 on the conveyor roller of the production line;

[0050] (2) Place the glass to be coated with a thickness of ≤1.5 mm on the rubber pad 3 on the top of the bracket body 1 by a manipulator, and use the adsorption effect of the rubber pad 3 to prevent the glass from moving during the transmission and coating process;

[0051] (3) After the coating is completed, the coated glass is removed by a robot, and the substrate rack is transported to the loading station through a vertical transmission line, so that it can be reused repeatedly.

[0052] The above-mentioned cycle operation is fully automatically controlled and requires no human intervention, with a production cycle of 15 seconds per piece of glass.

[0053] After testing, the positioning accuracy of the glass adsorbed on the substrate holder is ±1mm; the position accuracy of the substrate holder transmission is ±10mm; the influence of the substrate holder on the vacuum degree of the coating chamber is less than 3%; the substrate holder can be reused more than 10,000 times, and the substrate holders in the shape of a semicircle, triangle and rectangle can be reused more than 15,000 times; the length and width deformation of the substrate holder is ≤0.2%.

[0054] Comparative Application Example 1

[0055] This comparative application example uses the substrate rack provided in Comparative Example 1 to carry the glass to be coated in a horizontal coating production line, and specifically includes the following steps:

[0056] (1) The substrate holder is placed on the surface of the conveyor roller by a manipulator and the positioning pin 2 is inserted, thereby fixing the bracket body 1 on the conveyor roller of the production line;

[0057] (2) Using a robot, place the glass to be coated with a thickness of ≤1.5 mm on the top of the bracket body 1;

[0058] (3) After the coating is completed, the coated glass is removed by a robot, and the substrate rack is transported to the loading station through a vertical transmission line, so that it can be reused repeatedly.

[0059] Compared with Application Examples 1-4, the substrate rack used in this comparative application example does not have a rubber pad 3 on the top of the bracket body 1, which causes the glass to move easily during the transmission and coating process, thereby causing a series of quality defects such as scratches on the plate or roller marks.

[0060] It can be seen that in order to solve the problem that the roller part of the ordinary horizontal coating production line directly contacts the glass surface and easily reduces the glass yield, the substrate rack provided by the utility model is located between the transmission roller of the production line and the glass to be coated, and the glass to be coated is adsorbed on the rubber pad of the substrate rack and has no direct contact with the transmission roller, thereby effectively avoiding a series of quality defects such as surface scratches or roller marks on the ultra-thin glass when it is transmitted on the roller, thereby improving the glass yield. At the same time, the substrate rack has a simple structure, reduces the design cost, and is conducive to large-scale promotion and application.

[0061] The applicant declares that the above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Technicians in the relevant technical field should understand that any changes or substitutions that can be easily thought of by technicians in the relevant technical field within the technical scope disclosed in the present invention fall within the protection scope and disclosure scope of the present invention.
