An adsorption mechanism and a pre-lamination device

Abstract

The present invention discloses an adsorption mechanism and a pre-lamination device, belonging to the technical field of display device manufacturing. The adsorption mechanism includes a support part and an adsorption part. The support part has an adsorption surface, and the adsorption surface includes a display area located in the middle, a border area surrounding the display area, and a waste material area surrounding the border area. The adsorption part is arranged on the adsorption surface, and the adsorption part includes a plurality of suction cups for adsorbing a glass substrate, and suction cups are arranged in the display area. Since there is an evaporation coating film in the display area of the glass substrate while the border area is transparent, the suction cups in the display area will not leave marks on the glass substrate due to the blockage of the evaporation coating film. The suction cups are located in the display area, so the suction cups will not contact the border of the glass substrate, and thus will not leave marks in the border area of the glass substrate, improving the quality of the glass substrate. The pre-lamination device includes the above adsorption mechanism.

Description

Technical Field

[0001] The present invention relates to the technical field of display device manufacturing, and particularly relates to an adsorption mechanism and a pre-bonding device. Background Art

[0002] As an important component of a display device, the performance of a display panel directly affects the display effect of the display device. The display panel includes a display area, a border area surrounding the display area, and a waste area surrounding the border area. When the display panel is manufactured, the waste area is cut off, and only the display area and the border area are retained.

[0003] During the process of manufacturing a display panel, an evaporation coating film is formed on a glass substrate through an etching process, and then a metal film is attached to the evaporation coating film. When attaching the metal film, an adsorption mechanism is required to adsorb the glass substrate and move it to the position to be bonded.

[0004] Most of the existing adsorption mechanisms use suction cups to adsorb the glass substrate. In order to increase the adsorption area, when the suction cup adsorbs the glass substrate, it will not only adsorb at the position corresponding to the display area, but also adsorb at the position corresponding to the border area, resulting in stripes in the border area after the display panel is formed, affecting the quality of the display panel and increasing the defective rate of the product. Summary of the Invention

[0005] The purpose of the present invention is to provide an adsorption mechanism and a pre-bonding device to solve the technical problem that stripes are formed in the border area of the display panel when the glass substrate is adsorbed in the prior art.

[0006] As conceived above, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, an adsorption mechanism is provided, including:

[0008] A support part having an adsorption surface, the adsorption surface including a display area located in the middle, a border area surrounding the display area, and a waste area surrounding the border area;

[0009] An adsorption part provided on the adsorption surface, the adsorption part including a plurality of suction cups for adsorbing a glass substrate;

[0010] The suction cups are provided in the display area;

[0011] The display area matches the range position of the display area of the glass substrate, the border area matches the range position of the border area of the glass substrate, and the waste area matches the range position of the waste area of the glass substrate.

[0012] As a preferred solution of the adsorption mechanism, the suction cups are provided in the waste area.

[0013] As a preferred embodiment of the adsorption mechanism, the suction cups within the display area are main suction cups, and there are multiple main suction cups. The multiple main suction cups are arranged in an array within the display area; the suction cups within the waste material area are auxiliary suction cups, and there are multiple auxiliary suction cups. The multiple auxiliary suction cups are arranged in a ring around the waste material area.

[0014] As a preferred embodiment of the adsorption mechanism, the main suction cups are circular suction cups, and the auxiliary suction cups are strip-shaped suction cups.

[0015] As a preferred embodiment of the adsorption mechanism, multiple first accommodation grooves are provided on the support portion within the display area, and the main suction cups are fixed within the first accommodation grooves.

[0016] As a preferred embodiment of the adsorption mechanism, the main suction cup includes:

[0017] A first base, connected to the support portion, the first base having a first card slot;

[0018] A first adsorption pad, clamped in the first card slot, the first adsorption pad being capable of adsorbing the glass substrate.

[0019] As a preferred embodiment of the adsorption mechanism, an avoidance hole is provided at the middle position of the first base, and an airbag is provided at the position on the support portion opposite to the avoidance hole. By inflating and deflating the airbag, the airbag can be in an inflated state and a contracted state. The airbag in the contracted state is located within the avoidance hole, and the airbag in the inflated state protrudes outside the avoidance hole.

[0020] As a preferred embodiment of the adsorption mechanism, multiple protrusions are provided on the surface of the first adsorption pad, and the protrusions can abut against the glass substrate.

[0021] As a preferred embodiment of the adsorption mechanism, the auxiliary suction cup includes:

[0022] A second base, connected to the support portion, the second base having a second card slot;

[0023] A second adsorption pad, clamped in the second card slot, the second adsorption pad being capable of adsorbing the glass substrate.

[0025] A frame;

[0026] A lower top plate, arranged on the frame and used for carrying the metal film;

[0027] The upper top plate is arranged above the lower top plate and is spaced parallel from the lower top plate, and the adsorption mechanism is connected to the upper top plate.

[0028] The beneficial effects of the present invention are as follows:

[0029] For the adsorption mechanism provided by the present invention, a plurality of suction cups are arranged on the adsorption surface of the support part. When adsorbing the glass substrate, the display area of the support part matches the range position of the display area of the glass substrate, and the frame area of the support part matches the range position of the frame area of the glass substrate. Since the display area of the glass substrate is provided with an evaporation coating and the frame area is transparent, the stripes left by the suction cups in the display area on the glass substrate will not be visible due to the occlusion of the evaporation coating; since the suction cups are arranged in the display area, the suction cups will not contact the frame of the glass substrate, and thus no stripes will be left in the frame area of the glass substrate, improving the quality of the glass substrate.

[0030] For the pre-fitting device provided by the present invention, due to the adoption of the above adsorption mechanism, no stripes will be left in the frame area of the glass substrate, improving the pre-fitting quality. Description of the Drawings

[0041] Referring to the embodiments described in detail below with reference to the drawings, the advantages and features of the present invention and the methods for realizing them will become apparent. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. The provision of the present embodiments is only to complete the disclosure of the present invention and enable those skilled in the art to fully understand the scope of the present invention, and the present invention is only defined by the scope of the claims. The same reference numerals represent the same components throughout the specification.

[0042] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0043] See Figure 1 , an embodiment of the present invention provides a pre-laminating device for pre-laminating a metal film 100 with an evaporated film on a glass substrate 200. The pre-laminating device includes a frame 10, an upper top plate 20, a lower top plate 30, and an adsorption mechanism 40. The upper top plate 20 and the lower top plate 30 are both connected to the frame 10. The upper top plate 20 is disposed above the lower top plate 30 and is arranged in parallel and spaced apart from the lower top plate 30. The adsorption mechanism 40 is connected to the upper top plate 20.

[0044] The adsorption mechanism 40 can be detachably connected to the upper top plate 20 for easy maintenance. The adsorption mechanism 40 can be integrally formed with the upper top plate 20 to reduce the number of components and simplify the structure.

[0045] The lower top plate 30 is used to carry the metal film 100, and the upper top plate 20 is used to carry the glass substrate 200. Specifically, the metal film 100 is located on the upper surface of the lower top plate 30, and the adsorption mechanism 40 is located on the lower surface of the upper top plate 20. The adsorption mechanism 40 is used to adsorb the glass substrate 200.

[0046] The upper top plate 20 is slidably connected to the frame 10. When the upper top plate 20 moves downward, it can drive the glass substrate 200 to move downward, so that the evaporated film on the glass substrate 200 is pre-laminated with the metal film 100.

[0047] See Figure 2 , the adsorption mechanism 40 provided by the embodiment of the present invention includes a support part 1 and an adsorption part 2. The support part 1 has an adsorption surface 11. The adsorption surface 11 includes a display area 111 located in the middle, a border area 112 surrounding the display area 111, and a waste area 113 surrounding the border area 112. The adsorption part 2 is disposed on the adsorption surface 11. The adsorption part 2 includes a plurality of suction cups for adsorbing the glass substrate 200.

[0048] When the suction cup adsorbs the glass substrate 200, the display area 111 of the adsorption surface 11 matches the position of the display area range of the glass substrate 200, the border area 112 of the adsorption surface 11 matches the position of the border area range of the glass substrate 200, and the waste material area 113 of the adsorption surface 11 matches the position of the waste material area range of the glass substrate 200. Therefore, the sizes and shapes of the display area 111, the border area 112, and the waste material area 113 are set according to the sizes of the display area, the border area, and the waste material area of the glass substrate 200 to be adsorbed.

[0049] Suction cups are arranged in the display area 111. Since the display area of the glass substrate 200 is provided with an evaporation coating and the border area is transparent, the stripes left by the suction cups in the display area 111 will not be visible due to the blockage of the evaporation coating; the suction cups are arranged in the display area 111, so the suction cups will not contact the border of the glass substrate 200, and thus will not leave stripes in the border area of the glass substrate 200, improving the quality of the glass substrate 200.

[0050] Here, there is no limitation on the shape of the support portion 1, and the support portion 1 can be circular or rectangular. The display area 111 can be a regular circle or rectangle.

[0051] Multiple suction cups can be distributed only in the display area 111. Multiple suction cups can also be distributed in the display area 111 and the waste material area 113 at the same time, enabling a larger adsorption area.

[0052] In this embodiment, suction cups are arranged in the waste material area 113. Since the waste material area of the glass substrate 200 will be cut, the stripes left by the suction cups in the waste material area will not be visible on the glass substrate 200.

[0053] The suction cups in the display area 111 are main suction cups 21, and there are multiple main suction cups 21. The multiple main suction cups 21 are arranged in an array in the display area 111. The suction cups in the waste material area 113 are auxiliary suction cups 22, and there are multiple auxiliary suction cups 22. The multiple auxiliary suction cups 22 are arranged in a ring around the waste material area 113.

[0054] Here, there is no limitation on the shape of the suction cup. The main suction cup 21 can be circular or rectangular, and the auxiliary suction cup 22 can be circular or rectangular.

[0055] In this embodiment, the main suction cup 21 is a circular suction cup. The circular suction cup is convenient for processing and production. In this embodiment, the auxiliary suction cup 22 is a strip-shaped suction cup. Since the waste material area of the glass substrate 200 is narrow, arranging strip-shaped suction cups can make more full use of the area of the waste material area 113.

[0056] A plurality of main suction cups 21 are arranged in an array in the display area 111, making full use of the area of the display area 111 so that the glass substrate 200 can be uniformly stressed. A plurality of auxiliary suction cups 22 are arranged in a ring around the remaining material area 113, making full use of the area of the remaining material area 113 so that the edge of the glass substrate 200 can be uniformly stressed.

[0057] See Figure 3 and Figure 4 The main suction cup 21 includes a first base 211 and a first adsorption pad 212. The first base 211 is connected to the support portion 1. The first base 211 has a first card slot 2111, and the first adsorption pad 212 is clamped in the first card slot 2111. The first adsorption pad 212 can adsorb the glass substrate 200.

[0058] The material of the first adsorption pad 212 is silica gel, and the adsorption of the first adsorption pad 212 to the glass substrate 200 utilizes the inherent adhesiveness of silica gel itself.

[0059] On the adsorption surface 11 of the support portion 1, a plurality of first accommodation grooves 12 are provided in the display area 111. The main suction cups 21 are fixed in the first accommodation grooves 12, and one main suction cup 21 is provided in each first accommodation groove 12. Specifically, the first base 211 and the support portion 1 are connected by bolts. Through holes are provided on the first base 211, threaded holes are provided in the first accommodation grooves 12 of the support portion 1, and the bolts pass through the through holes and are connected to the threaded holes. Among them, the through holes are countersunk holes to accommodate the heads of the bolts.

[0060] The surface of the first adsorption pad 212 is provided with a plurality of protrusions 213, and the protrusions 213 can abut against the glass substrate 200. When adsorbing the glass substrate 200, the protrusions 213 are squeezed and deformed, and the air in the gaps between the protrusions 213 is squeezed out, so that a negative pressure is formed on the surface of the first adsorption pad 212, which can increase the adsorption force on the glass substrate 200 and make the adsorption effect better.

[0061] In this embodiment, the first adsorption pad 212 and the protrusions 213 are integrally formed, which is convenient for processing and production. The materials of the first adsorption pad 212 and the protrusions 213 are both silica gel, and the adsorption of the first adsorption pad 212 and the protrusions 213 to the glass substrate 200 utilizes the inherent adhesiveness of silica gel itself.

[0062] In order to release the glass substrate 200, an avoidance hole 2112 is provided at the middle position of the first base 211, and an airbag 23 is provided at the position of the support portion 1 opposite to the avoidance hole 2112. By inflating and deflating the airbag 23, the airbag 23 can be in an inflated state and a contracted state. The airbag 23 in the contracted state is located in the avoidance hole 2112, and the airbag 23 in the inflated state protrudes out of the avoidance hole 2112.

[0063] In this embodiment, the first card slot 2111 and the first adsorption pad 212 are annular, and the first card slot 2111 is disposed around the avoidance hole 2112.

[0064] When the airbag 23 is in a contracted state, the airbag 23 is located within the avoidance hole 2112 and will not affect the suction cup's adsorption of the glass substrate 200. When the airbag 23 is in an inflated state, the airbag 23 protrudes outside the avoidance hole 2112, applying a thrust force to the glass substrate 200 to cause the glass substrate 200 to disengage from the suction cup.

[0065] See Figure 5 , the auxiliary suction cup 22 includes a second base 221 and a second adsorption pad 222. The second base 221 is connected to the support portion 1. The second base 221 has a second card slot 2211, and the second adsorption pad 222 is clamped in the second card slot 2211. The second adsorption pad 222 can adsorb the glass substrate 200. The material of the second adsorption pad 222 is silica gel, and the adsorption of the second adsorption pad 222 to the glass substrate 200 utilizes the inherent adhesiveness of silica gel itself.

[0066] On the adsorption surface 11 of the support portion 1, a plurality of second accommodation grooves 13 are provided in the waste material area 113. The auxiliary suction cup 22 is fixed in the second accommodation groove 13, and one auxiliary suction cup 22 is provided in each second accommodation groove 13. Specifically, the second base 221 and the support portion 1 are connected by bolts. A through hole is provided on the second base 221, and a threaded hole is provided in the second accommodation groove 13 of the support portion 1. The bolt passes through the through hole and is connected to the threaded hole. Among them, the through hole is a counterbore to accommodate the head of the bolt.

[0067] In addition, the adsorption mechanism 40 further includes a bracket and a driving mechanism. The driving mechanism is disposed on the bracket, and the output end of the driving mechanism is connected to the support portion 1. The driving mechanism can drive the support portion 1 to shift. Among them, the driving mechanism can be a manipulator, which will not be elaborated here.

[0068] When sucking the glass substrate 200, the adsorption mechanism 40 has an adsorption state and a release state.

[0069] When the airbag 23 is in a contracted state, the airbag 23 is located within the avoidance hole 2112. The adsorption mechanism 40 is shifted to a position where the support portion 1 matches the range of the glass substrate 200. At this time, the display area 111 matches the range of the display area of the glass substrate 200, the border area 112 matches the range of the border area of the glass substrate 200, and the waste material area 113 matches the range of the waste material area of the glass substrate 200. The support portion 1 is moved to make the adsorption surface 11 fit with the glass substrate 200, so that the main suction cup 21 and the auxiliary suction cup 22 adsorb the glass substrate 200. Since the airbag 23 is located within the avoidance hole 2112, it will not affect the adsorption. At this time, the adsorption mechanism 40 is in the adsorption state.

[0070] When the glass substrate 200 is moved to the set position, the airbag 23 is inflated so that the airbag 23 is in an inflated state. The airbag 23 protrudes outside the avoidance hole 2112 and can apply a thrust to the glass substrate 200, causing the glass substrate 200 to disengage from the suction cup. At this time, the adsorption mechanism 40 is in a released state.

[0071] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be manufactured in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or basic features of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
