Description

Technical Field

[0001] The present application relates to the technical field of coating equipment, and in particular to a substrate rack for loading glass substrates. Background Art

[0002] Glass substrates are commonly used substrates for coating workpieces. In coating equipment, substrate racks are used to load and transport glass substrates. During specific operations, the glass substrates are first loaded on the substrate racks, and then transported to the coating equipment for coating by the transport substrate racks. After coating, the substrate racks transport the coated glass substrates out of the coating equipment and unload the glass substrates.

[0003] In the prior art, a clip-type clamp is mainly used to fix the glass substrate. For example, patent CN104891818A discloses a carrier used in a coating device. A plurality of clamps are arranged around the carrier. Each clamp includes a fixed clamp and a movable clamp connected by a torsion spring. When in use, the clamp is opened by pressing the pressing end of the movable clamp. By canceling the pressing force on the movable clamp, the clamp is closed under the action of the restoring force of the torsion spring. Although the structure of the clamp is simple, it is not convenient for installing and unloading the glass substrate. In addition, the stability of the carrier in transporting the glass substrate is poor, which easily causes damage to the glass substrate. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] See also Figures 1 to 6 In the illustrated embodiment, the present application provides a substrate rack, including a frame 100 and a first clamping assembly 200, wherein the frame 100 is adapted to a glass substrate and has a loading space adapted to the glass substrate; the first clamping assembly 200 is disposed on at least one side of the frame 100, and the first clamping assembly 200 includes a first base 210, a first clamping member 220, and a first abutting member 230, wherein the first clamping member 220 is slidable relative to the first base 210 and has a first hook 240 that cooperates with an edge of the glass substrate, the first abutting member 230 is fixedly disposed relative to the first base 210 and can be abutted against the side of the glass substrate during operation, and in addition, an elastic member 250 is disposed between the first clamping member 220 and the first base 210.

[0030] In this embodiment, the first clamping member 220 has a first moving direction close to the frame 100 and a second moving direction away from the frame 100 relative to the frame 100. When working, the first clamping member 220 is driven to slide along the first moving direction, which can provide more space for the glass substrate to enter the substrate rack, and facilitate the implantation of the glass substrate on the substrate rack; after the glass substrate is implanted, the first clamping member 220 will slide along the second moving direction due to the rebound effect of the elastic member 250, and the movable range of the side of the glass substrate and the loading space can be adjusted, thereby effectively fixing the glass substrate. When the glass substrate is to be unloaded, the first clamping member 220 is driven to slide along the first moving direction to release the activity restriction of the glass substrate, thereby facilitating the withdrawal of the glass substrate from the substrate rack.

[0031] See also Figure 3 In the illustrated embodiment, the first clamping assembly 200 further includes a slider 270 that is slidably matched with the first base 210, and the first clamping member 220 is connected to the slider 270. Specifically, the first base 210 has a free end extending horizontally toward the inside of the loading space, the first abutting member 230 is fixed to the free end, the slider 270 is arranged between the first abutting member 230 and the first base 210, and the elastic member 250 is arranged between the first base 210 and the slider 270. The elastic member 250 is a coil spring, one end of which is fixed to the first base 210, and the other end acts on the slider 270.

[0032] See also Figure 2 The first clamping member 220 and the first abutting member 230 have a first thermal insulation pad 260, wherein the first hook 240 is disposed on the first thermal insulation pad 260, and the first thermal insulation pad 260 is, for example, a thermal insulation pad of polyetheretherketone (PEEK), which is beneficial to reducing the risk of deformation of the edge of the glass substrate due to high temperature. Further, the first hook 240 and the first thermal insulation pad 260 are integrally formed.

[0033] To facilitate the entry of the glass substrate, the first hook 240 has a guiding slope 241 for guiding the glass substrate into the interior thereof.

[0034] See also Figure 5 In the illustrated embodiment, at least one side of the frame 100 is provided with a second clamping assembly 300, the second clamping assembly 300 includes a second base 310 and a second clamping member 320 fixedly disposed on the second base 310, the second clamping member 320 has a second hook 330, and when in use, the second hook 330 cooperates with the edge of the glass substrate to fix the glass substrate. The second clamping member 320 has a second thermal insulation pad 340, and the second hook 330 is disposed on the second thermal insulation pad 340. Further, the second thermal insulation pad 340 and the second hook 330 are integrally formed. The second thermal insulation pad 340 is, for example, a thermal insulation pad of polyetheretherketone (PEEK).

[0035] See also Figure 1 , 6 The frame 100 is a rectangular structure, wherein two adjacent sides are provided with first clamping assemblies 200, and two adjacent sides are provided with second clamping assemblies 300. Relative to the glass substrate, the two sides provided with the first clamping assemblies 200 are fixed sides, and the two sides provided with the second clamping assemblies 300 are movable sides. When loading the glass substrate, the glass substrate is implanted into the frame 100 from the fixed side, and then the glass substrate is clamped by the second clamping assembly 300 to limit the movement of the glass substrate.

[0036] Generally, the substrate rack has a lying state for facilitating loading and unloading of glass substrates and an upright state for transporting glass substrates. In one embodiment, in the upright state, the upper side 110 of the frame 100 is provided with a first clamping assembly 200, and the lower side 120 of the frame 100 is provided with a second clamping assembly 300 to limit the up and down shaking of the glass substrate. In addition, one of the left and right sides and the right side 140 of the frame 100 is provided with a first clamping assembly 200, and the other is provided with a second clamping assembly 300 to limit the left and right shaking of the glass substrate, thereby improving the stability of the glass substrate during transportation.

[0037] In the upright state, the bottom edge of the glass substrate is prone to deformation. In severe cases, the edge bulges outward and touches the shield of the substrate frame, causing damage to the edge and affecting the use of the glass substrate. To solve this problem, see Figure 1 A plurality of first clamping members 220 are disposed on one side of the frame 100. Among the plurality of first clamping members 220, the length of a portion of the second clamping members 320 is greater than the length of the remaining second clamping members 320, which can effectively improve the deformation of the edge of the glass substrate.

[0038] Specifically, the lower side 120 of the frame 100 is provided with a plurality of second clamping members 320 at intervals, wherein the lengths of two second clamping members 320 are greater than the lengths of the remaining second clamping members 320. For example, the lower side 120 is provided with eight second clamping members 320 at intervals, and the lengths of the second clamping members 320a located at the second position and the seventh position from left to right are greater than the lengths of the other second clamping members 320b, see Figure 6 .

[0039] Furthermore, a plurality of second clamping members 320 are disposed at intervals on the left side 130 of the frame 100, wherein the length of some second clamping members 320 is greater than the length of the remaining second clamping members 320, and specifically, the length of the second clamping member 320a at the left side 130 adjacent to the lower side 120 is greater than the length of the other second clamping members 320b. These designs are all conducive to improving the deformation of the bottom edge of the glass substrate.

[0040] The substrate rack provided in the present application facilitates the loading and unloading of the glass substrate and can ensure the stability of the glass substrate during the transmission process.
