Background

At present, many types of display panels are all provided with glass substrates, and along with the large-size trend of display panels, the size of the glass substrates is also bigger and bigger, and due to the fragile characteristic of glass, the larger the size of the glass substrates is, the higher the breaking risk of the glass substrates in the manufacturing process of the display panels is. For example, in a pvd (physical Vapor deposition) process of a display panel, a glass substrate needs to be fixed in an upright state by a carrier (e.g., Tray) and moved by the carrier driven by a gear. In the process, the gear drives the bearing assembly to generate vibration inevitably, and if the vibration is too severe, the glass substrate is easy to break.

The application does not limit the application scenario of the carrier assembly, i.e. the process applied to the glass substrate. To facilitate highlighting the improvements of the present application and the prior art, the present application is described below with reference to PVD processes in which the carrier assembly is used with a glass substrate.

The technical solutions of the embodiments of the present application are clearly and completely described below with reference to the accompanying drawings. The following embodiments and technical features thereof may be combined with each other without conflict. Also, directional terminology, such as "upper", "lower", etc., used throughout the description is for better describing the various embodiments and is not intended to limit the scope of the present application.

Fig. 1 is a schematic structural diagram of a load bearing assembly according to an embodiment of the present application, and fig. 2 is an exploded schematic structural diagram of the load bearing assembly shown in fig. 1. Referring to fig. 1 and 2, the bearing assembly 10 includes a mounting base 11, a supporting member 12 and an elastic member 13.

The mounting base 11 may be made of a metal material and is used for fixing and connecting to a component for holding the glass substrate in a predetermined posture. For example, as shown in fig. 4, in the PVD process, the member for holding the glass substrate in a predetermined posture is a frame 14 placed vertically, and the mounting base 11 may be mounted and fixed to a side surface (a region shown by a dotted line in the figure) of the frame 14 by screw locking or the like. Specifically, the mounting base 11 includes a functional portion 111 and a fixing portion 112 extending from the functional portion 111 toward two sides, the fixing portion 112 has a mounting hole 113, and the mounting base 11 can be fixed on the frame 14 by inserting fixing members such as screws into the mounting hole 113 one by one and screwing the fixing members with the frame 14.

The elastic element 13 is supported on the mounting base 11, specifically, a receiving hole 114 is formed in a side wall of the functional portion 111 of the mounting base 11, the elastic element 13 is inserted into the receiving hole 114, and an upper end of the elastic element 13 is exposed on a surface of the functional portion 111 in a natural state, that is, the elastic element 13 is exposed out of the receiving hole 114 and abuts against the supporting element 12.

The supporting member 12 is used for supporting a glass substrate, and specifically, as shown in fig. 1, the supporting member 12 may include a main body portion 121, a supporting portion 122, and a limiting member 123. The main body 121 may be a U-shaped structure and is provided with two through holes 124, and the two limiting members 123 respectively penetrate through the two through holes 124 and are fixed on the mounting base 11, it should be noted that the diameter of the limiting members 123 should be smaller than the inner diameter of the through holes 124, so that the supporting member 12 and the glass substrate supported thereon can move up and down under the expansion and contraction action of the elastic member 13. In a practical application scenario, the position-limiting element 123 may be a screw, and in order to achieve contact and matching between the position-limiting element 123 and the through hole 124, an inner hollow sleeve 125 may be sleeved outside the position-limiting element 123, and the sleeve 125 contacts with an inner wall of the through hole 124.

As shown in fig. 2 and 3, the bearing portion 122 is disposed on one side of the main body portion 121 and is used for bearing a glass substrate, an upper surface of the bearing portion 122 is lower than an upper surface of the main body portion 121 with the stopper 123 interposed therebetween, in addition, a stopper 126 is disposed on the upper surface of the bearing portion 122, a sidewall of the main body portion 121 and the stopper 126 are disposed at an interval, and the glass substrate is borne on the upper surface of the bearing portion 122 in an upright posture and is located between the sidewall of the main body portion 121 and the stopper 126.

Based on the above design, when the glass substrate is supported on the supporting member 12, the elastic member 13 can provide a shock absorption and buffering effect on the collision between the supporting member 12 and the mounting base 11, which is equivalent to providing a shock absorption and buffering effect on the glass substrate, so as to avoid the breakage of the glass substrate caused by severe vibration, thereby being beneficial to reducing the risk of the breakage of the glass substrate.

In an application scenario, the elastic member 13 may be a spring, and in order to avoid the spring 13 from shifting left and right when bearing the glass substrate, a limiting column may be disposed on the mounting base 11, the accommodating hole 114 is a blind hole, the limiting column is located in the blind hole and inserted into the spring 13, and a top end of the spring 13 abuts against the main body portion 121 of the supporting member 12.

Referring to fig. 1, a soft buffer 127 is further disposed on the upper surface of the supporting portion 122, and the soft buffer 127 is disposed between the sidewall of the main body portion 121 and the blocking element 126. When the glass substrate is supported on the supporting member 12, the glass substrate presses the soft buffer member 127 due to its own weight and vibration, and the soft buffer member 127 sags and deforms, so that the glass substrate can be stably supported on the supporting portion 122, and the glass substrate can be damped and buffered.

Based on this function, the soft buffer 127 may be a plurality of protrusions disposed on the upper surface of the supporting portion 122, the protrusions may be in the shape of a strip, and the plurality of strip-shaped protrusions are disposed at intervals, or the protrusions may be defined by a plurality of strip-shaped grooves. Further, for the application scenario where the bearing portion 122 is made of a plastic material, the soft buffer 127 and the bearing portion 122 may be an integrally formed structure.

The application also provides a substrate bearing and conveying device, which can be a device used for bearing and conveying the glass substrate in the PVD process. The substrate carrying and transferring apparatus may include the same structural design as the carrying assembly 10 shown in fig. 1, and thus has the same advantages as described above.

It should be noted that the above-mentioned embodiments are only examples of the present application, and not intended to limit the scope of the present application, and all equivalent structures or equivalent flow transformations made by the contents of the specification and the drawings, such as the combination of technical features between various embodiments, or the direct or indirect application to other related technical fields, are also included in the scope of the present application.
