Description
Technical Field
[0001] This utility model relates to the field of display device manufacturing technology, and in particular to a universal chuck for mounting display panels. Background Technology
[0002] In the vapor deposition process of display panels, a chuck is used to fix the display panel so that it faces downwards toward the vapor deposition crucible. The vapor deposition gas ejected from the crucible rises and deposits on the surface of the display panel. (Refer to...) Figure 1 As shown, a conventional chuck includes a substrate 1' and several support members 2' disposed on the substrate 1'. The support members 2' form a non-contact area 3'. In the vapor deposition process, a large sheet of glass (i.e., a display panel; for ease of explanation, the entire glass sheet before vapor deposition is also referred to as a display panel) is typically mounted on the chuck for vapor deposition. After all subsequent processes are completed, it is finally cut into multiple small display panels corresponding to the display. The scrap material discarded during the cutting of the large display panel can directly contact the support members 2'. Therefore, when mounting the chuck, the scrap material area on the display panel is bonded to the support members 2' using adhesive. The product area used to manufacture the display corresponds to the non-contact area 3'. The support members 2' protrude from the surface of the substrate 1', causing the product area of the display panel to be suspended in the non-contact area 3'.
[0003] The existing technology has the following shortcomings: Since the position of the support member 2′ on the substrate 1′ corresponds one-to-one with the specific dimensions of the product areas on the display panel, and the entire glass panel typically contains multiple product areas of different sizes, the size and layout of the product areas will change depending on the specific production task. Therefore, corresponding chucks are required for fixing different layouts of the display panel. This results in a large number of chuck models, occupying inventory space and increasing production costs. Utility Model Content
[0004] The purpose of this invention is to provide a universal chuck for installing display panels, which can adapt to various layout formats of display panels, has strong versatility, and helps to reduce production costs.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A universal chuck for mounting display panels is provided, comprising:
[0007] A substrate, wherein a mounting surface for mounting a display panel is formed on one side of the substrate along its thickness direction, and a plurality of mounting grooves are provided on the mounting surface, wherein the mounting grooves include a limiting groove located in the substrate and a clearance groove communicating with the limiting groove, and the clearance groove penetrates the mounting surface;
[0008] The support member is provided in each of the mounting slots. The support member includes a limiting part and a supporting part. The limiting part is located in the limiting slot and can move along the thickness direction of the substrate. One end of the supporting part is connected to the limiting part, and the other end passes through the clearance slot and can extend to the outside of the mounting slot. The end of the supporting part away from the limiting part is used to bond and fix it to the display panel.
[0009] A locking member is rotatably disposed on the substrate. The locking member is selectively clamped between the limiting part and the top wall of the limiting groove, or between the limiting part and the bottom wall of the limiting groove.
[0010] As a preferred embodiment of a universal chuck for mounting a display panel, the substrate is provided with a locking groove communicating with the limiting groove. The locking element includes a locking rod, a locking handle, and two locking heads. The two locking heads are spaced apart along the circumferential direction of the locking rod. One locking head is used to clamp between the limiting part and the top wall of the limiting groove, and the other locking head is used to clamp between the limiting part and the bottom wall of the limiting groove. One end of the locking rod for mounting the locking head is located in the locking groove, and the other end of the locking rod opposite to the locking head extends to the outside of the substrate and connects to the locking handle.
[0011] As a preferred embodiment of a universal chuck for mounting a display panel, the two locking heads are located on opposite sides of the locking lever.
[0012] As a preferred embodiment of a universal chuck for mounting display panels, the cross-section of the lock head gradually increases from the end to the middle of the lock head along the circumferential direction of the locking rod.
[0013] As a preferred embodiment of a universal chuck for mounting display panels, the chuck handle is provided with markings that correspond one-to-one with the two lock heads.
[0014] As a preferred embodiment of a universal chuck for mounting display panels, the support portion is provided with a plurality of glue reservoirs at intervals at one end away from the limiting portion for holding adhesive liquid.
[0015] As a preferred embodiment of a universal chuck for mounting a display panel, at least two locking elements are provided on opposite sides of the support member, and the locking elements on the same side are spaced apart along the length of the support member.
[0016] As a preferred embodiment of a universal chuck for mounting display panels, the support portion has grooves on both sides in the width direction.
[0017] As a preferred embodiment of a universal chuck for mounting a display panel, it also includes an airbag surrounding the periphery of the substrate, the airbag being used to drive the display panel to separate from the support member.
[0018] As a preferred embodiment of a universal chuck for mounting a display panel, some of the support members are divided into multiple groups and arranged at intervals along a first direction, with the airbags provided between adjacent groups of support members.
[0019] The advantages of this utility model compared to the prior art are:
[0020] This utility model discloses a universal chuck for mounting display panels. By telescopically installing a support member within a mounting slot and securing it in either the extended or retracted state using a locking mechanism, the appropriate support member can be selected to connect to the display panel according to different panel layouts. Specifically, the support member that meets the panel's material requirements is extended and bonded to the excess material area of the display panel. Conversely, the support member that does not meet the material requirements is retracted to create a gap between it and the display panel, preventing interference with the panel's product area. Therefore, this universal chuck for mounting display panels can adapt to various display panel layouts, possessing strong versatility and achieving multiple uses with a single component, thus helping to reduce production costs.

[0033] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.
[0034] The present invention will now be described in detail with reference to the accompanying drawings.
[0035] like Figures 2 to 4As shown, this utility model embodiment provides a universal chuck for mounting a display panel 5, used to fix the display panel 5 so as to transport the display panel 5 above the vapor deposition crucible. The universal chuck for mounting the display panel includes a substrate 1, a support member 2, and a locking member 3. The substrate 1 is a rectangular flat plate structure made of aluminum. The length direction of the substrate 1 is the X direction shown in the figure, the width direction is the Y direction shown in the figure, and the thickness direction is the Z direction shown in the figure. A mounting surface 10 is formed on one side of the substrate 1 along its thickness direction, and the display panel 5 is mounted on the mounting surface 10. A plurality of mounting grooves 11 are provided on the mounting surface 10, the number and position of which correspond one-to-one with the support member 2. The mounting grooves 11 are used to mount the support member 2. The mounting grooves 11 are T-shaped grooves, including a limiting groove 111 and a clearance groove. The limiting groove 111 is located inside the substrate 1, and the clearance groove is located in the middle of the width direction (Y direction shown in the figure) of the limiting groove 111. One end of the clearance groove communicates with the limiting groove 111, and the other end penetrates through the mounting surface 10. The support member 2 is used to support the display panel 5. The cross-section of the support member 2 is T-shaped. The support member 2 includes a limiting part 21 and a supporting part 22. The limiting part 21 is a rectangular flat plate structure. The limiting part 21 is located in the limiting groove 111. The length and width of the limiting part 21 are the same as those of the limiting groove 111. The thickness of the limiting part 21 is less than the depth of the limiting groove 111, so that the limiting part 21 can move along the thickness direction of the substrate 1 (i.e., the depth direction of the limiting groove 111). One end of the supporting part 22 is connected to the limiting part 21, and the other end passes through the clearance groove and can extend to the outside of the mounting groove 11. The end of the supporting part 22 away from the limiting part 21 is used to bond and fix it to the display panel 5. In other words, by the limiting part 21 moving along the thickness direction of the substrate 1 within the limiting groove 111, the entire support member 2 can move telescopically relative to the substrate 1. The locking member 3 is used to lock and unlock the support member 2 to limit and fix the support member 2. The locking member 3 is rotatably mounted on the base plate 1. The locking member 3 can be clamped between the limiting part 21 and the top wall of the limiting groove 111, or between the limiting part 21 and the bottom wall of the limiting groove 111. (Refer to...) Figure 3 As shown, when the locking member 3 is clamped between the bottom wall of the limiting part 21 and the limiting groove 111, the entire support member 2 extends relative to the substrate 1, and the support member 2 is in use. The display panel 5 is mounted on the support part 22, and at this time, there is a certain distance between the display panel 5 and the substrate 1. (Refer to...) Figure 4 As shown, when the locking member 3 is clamped between the top groove wall of the limiting part 21 and the limiting groove 111, the entire support member 2 is shortened relative to the substrate 1, the support member 2 is in a non-use state, and the support member 2 is not connected to the display panel 5.
[0036] It is understood that a universal chuck for mounting the display panel is used to mount the display panel 5, and the size of the display panel 5 is approximately the same as the size of the substrate 1. The display panel 5 has a scrap area for later cutting and disposal; only this scrap area can contact the universal chuck used to mount the display panel. Therefore, the position of the support member 2 corresponds to the scrap area on the display panel 5. When the product area in the display panel 5 is large, support members 2 can be set around the product area, i.e., four support members 2 are used to surround the periphery of the product area, forming a non-contact area 100, on which the product area is suspended. When the product area in the display panel 5 is small, support members 2 can be set on opposite sides of the product area, i.e., two support members 2 are respectively set at opposite ends of the product area. In this embodiment, by telescopically installing the support member 2 in the mounting groove 11 and fixing the extended or shortened support member 2 with the locking member 3, the appropriate position of the support member 2 can be selected to connect to the display panel 5 according to different layout forms of the display panel 5. The support member 2, which conforms to the material requirements of the display panel 5, is extended and bonded to the material area of the display panel 5. The support member 2, which does not conform to the material requirements of the display panel 5, is retracted to create a gap between it and the display panel 5, thus avoiding interference with the product area of the display panel 5. Therefore, this universal chuck for mounting display panels can adapt to various layouts of display panels 5, possessing strong versatility and achieving multiple uses, which helps reduce production costs.
[0037] Specifically, a plurality of adhesive reservoirs 23 are provided at one end of the support portion 22 away from the limiting portion 21, and the plurality of adhesive reservoirs 23 are spaced apart along the length direction of the support member 2. The adhesive reservoirs 23 are used to hold adhesive liquid. During installation, the adhesive liquid is injected into the adhesive reservoirs 23 to prevent the adhesive liquid from spreading arbitrarily to the surrounding area. Then the display panel 5 is placed on the support member 2 to bond the display panel 5 to the support member 2. Grooves 24 are provided on both sides of the support portion 22 in the width direction, and the grooves 24 are located at the end of the support portion 22 near the adhesive reservoirs 23. By providing the grooves 24, it is convenient for the operator to hold the support portion 22 to pull the support member 2 upward. A plurality of support members 2 are provided on the substrate 1, wherein some support members 2 are spaced apart along the length direction of the substrate 1, and some support members 2 are spaced apart along the width direction of the substrate 1. The specific arrangement of the support members 2 is adapted to the processing size of the display panel 5 in the production task. This embodiment does not limit the specific arrangement of the support members 2. At least two locking elements 3 are provided on opposite sides of the support member 2, with the locking elements 3 on the same side spaced apart along the length of the support member 2. Since each locking element 3 is connected to one side of the support member 2, locking elements 3 need to be provided on both sides of the support member 2 to ensure overall force balance of the support member 2. In this embodiment, the locking elements 3 are provided on both sides of the support member 2 in the width direction. Two locking elements 3 are provided at intervals on each side of the support member 2 in the width direction.
[0038] Specifically, refer to Figures 3 to 5 As shown, a locking groove 12 is provided in the base plate 1, which is used to install the locking member 3. The locking groove 12 communicates with the limiting groove 111 so that the locking member 3 can move into the limiting groove 111 when rotated. The locking member 3 includes a locking rod 31, a locking handle 32, and two locking heads 33. The locking heads 33 are used to lock the support member 2. The two locking heads 33 are spaced apart along the circumferential direction of the locking rod 31. By rotating the locking rod 31, one of the locking heads 33 can be turned toward the support member 2. The positions of the two locking heads 33 on the locking rod 31 correspond to the extended and shortened positions of the support member 2. One locking head 33 is used to clamp between the limiting part 21 and the top groove wall of the limiting groove 111, and the other locking head 33 is used to clamp between the limiting part 21 and the bottom groove wall of the limiting groove 111. One end of the locking lever 31, used for mounting the lock head 33, is located within the locking groove 12. The other end of the locking lever 31, away from the lock head 33, extends to the outside of the base plate 1 and connects to the locking handle 32. The locking handle 32 is for the operator to grip and rotate the locking lever 31. To facilitate the operator's external determination of the lock head 33's exact location, the locking handle 32 is provided with a marking 34, which corresponds one-to-one with the two lock heads 33. The operator can determine the exact location of the lock head 33 by referring to the marking 34 on the locking handle 32. The marking 34 can be a text marking, a graphic marking, or a color mark, etc. The locking handle 32 should be lower than the top of the support part 22 to avoid interfering with the installation of the display panel 5.
[0039] The two lock cylinders 33 are located on opposite sides of the locking bar 31. (Refer to...) Figure 3 As shown, when the support member 2 is in use, it is pulled upwards, and the top surface of the limiting part 21 abuts against the top wall of the limiting groove 111. The lower locking head 33 is clamped between the limiting part 21 and the bottom wall of the limiting groove 111. When the support member 2 is not in use, it moves downwards, and the bottom surface of the limiting part 21 abuts against the bottom wall of the limiting groove 111. The upper locking head 33 is clamped between the limiting part 21 and the top side wall of the limiting groove 111. To change the support member 2 from the use state to the non-use state, simply rotate the locking member 3 so that both locking heads 33 rotate into the locking groove 12 and move away from the support member 2. At this time, the support member 2 can move up and down within the limiting groove 111.
[0040] To facilitate the smooth insertion of the lock head 33 between the limiting part 21 and the groove wall of the limiting groove 111, the cross-section of the lock head 33 gradually increases from its end to its middle along the circumferential direction of the locking rod 31. This can also be understood as the lock head 33 having a structure that is smaller at the end and larger in the middle. Since the lock head 33 is inserted between the limiting part 21 and the groove wall of the limiting groove 111 through the rotation of the locking rod 31, the end of the lock head 33 is inserted between the limiting part 21 and the groove wall of the limiting groove 111 first. The lock head 33's structure of being smaller at the end and larger in the middle makes it easier to insert between the limiting part 21 and the groove wall of the limiting groove 111.
[0041] In another embodiment, reference is made to Figure 6 and Figure 7 As shown, the universal chuck used to mount the display panel also includes an air bladder 4, which surrounds the periphery of the substrate 1. The air bladder 4 is used to drive the display panel 5 to separate from the support member 2. After the display panel 5 has been vapor-deposited, it needs to be removed from the universal chuck used to mount the display panel. By inflating the air bladder 4, the air bladder 4 expands and causes the display panel 5 to separate from the support member 2.
[0042] Specifically, among the multiple support members 2, some support members 2 are arranged in multiple groups, with each group containing multiple support members 2. In practical applications, a support member 2 in a suitable position is selected from each group and connected to the display panel 5. The multiple groups of support members 2 are arranged at intervals along the first direction (the width direction of the substrate 1), and an airbag 4 is provided between adjacent groups of support members 2. The function of the airbag 4 is to remove the display panel 5; therefore, the airbag 4 is positioned close to the support member 2. The number and position of the airbags 4 can be reasonably arranged according to the specific structure of the universal chuck used to install the display panel. Airbags 4 are provided at both the periphery and the center of the substrate 1, which helps to make the overall force on the display panel 5 more uniform.
[0043] In this embodiment, the working principle of the universal chuck used for installing the display panel is as follows: When installing the display panel 5, the required support member 2 is selected from several support members 2 to fit the position of the remaining material area on the display panel 5. The required support member 2 is pulled upward, and the locking member 3 is rotated so that the corresponding locking head 33 is inserted between the limiting part 21 and the bottom wall of the limiting groove 111. Then, the unused support member 2 is pressed down so that the unused support member 2 is lower than the required support member 2. The locking member 3 is rotated so that the corresponding locking head 33 is inserted between the limiting part 21 and the top wall of the limiting groove 111. At this time, some of the required support members 2 on the substrate 1 are relatively high and in use; the other part of the unused support members 2 are relatively low and in non-use. Then, glue is injected into the glue reservoir 23 of the support member 2 in use, and the display panel 5 is placed on the support member 2 so that the display panel 5 is bonded and fixed to the support member 2 in use. Then, the universal chuck is flipped over so that the display panel 5 faces downward so that it faces the vapor deposition crucible for vapor deposition treatment. After the vapor deposition is completed, the universal chuck used to mount the display panel is flipped so that the display panel 5 faces upward. Finally, the airbag 4 is inflated, causing the airbag 4 to inflate and drive the display panel 5 upward, ultimately separating the display panel 5 from the support member 2.
[0044] The beneficial effects of this embodiment are as follows: By telescopically installing the support member 2 within the mounting groove 11 and fixing the support member 2 in its extended or shortened state using the locking member 3, a suitable position of the support member 2 can be selected to connect to the display panel 5 according to different layout forms of the display panel 5. Specifically, the support member 2 that meets the material requirements of the display panel 5 is extended and bonded to the material area of the display panel 5. The support member 2 that does not meet the material requirements of the display panel 5 is retracted to create a gap between it and the display panel 5, thus avoiding interference with the product area of the display panel 5. Therefore, this universal chuck for mounting display panels can adapt to various layout forms of display panels 5, has strong versatility, achieves multiple uses, and helps reduce production costs.
[0045] Although 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 made 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 essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
