Description

Technical Field

[0001] This utility model mainly relates to the field of glass coating technology, specifically to a clamping device for reducing glass sway. Background Technology

[0002] In magnetron sputtering coating, the fixture plays a role in fixing the glass substrate and ensuring that it maintains the correct position during sputtering. However, the glass is prone to shaking when the carrier moves, which may cause the glass to fall off in actual production. This not only affects the output, but if the glass falls into the cavity and blocks the target material, it needs to be opened and processed, which often delays a lot of production time.

[0003] The main reason for glass substrate detachment is that the clamp cannot stably hold the glass substrate. The inventors proposed a clamping device to reduce glass wobbling. Modified high-temperature resistant silicone rubber or other elastic materials are added at the contact position between the clamp and the glass substrate to prevent the glass substrate from wobbling on the clamp and reduce the probability of glass substrate detachment in the magnetron sputtering coating process. Utility Model Content

[0004] 1. Technical problem solved by the utility model:

[0005] This invention provides a clamping device to reduce glass sway, solving the technical problem of insufficient clamping stability in existing equipment.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is: a clamping device for reducing glass swaying, comprising the following structure:

[0008] Two supports are provided, with a lower crossbar and an upper crossbar fixedly connected to the bottom and top of the two supports respectively by bolts.

[0009] The positioning piece has a diagonal pull tab fixedly attached to its bottom left and / or right ends, a card holder fixedly attached to its bottom, and a protective pad fixedly attached to the inner wall of the card holder's opening.

[0010] The protective gasket can be made of modified high-temperature resistant silicone rubber.

[0011] Furthermore, the top of the lower crossbar is detachably and equally spaced with multiple limiting clips, the top center of which is engaged with the bottom of the glass substrate.

[0012] Furthermore, the bottom of the upper crossbar is provided with multiple positioning holes at equal intervals, and the bottom of the upper crossbar is threaded with a positioning bolt, the top of which is threaded with the positioning hole.

[0013] Furthermore, the positioning plate has symmetrically formed positioning grooves at its left and right ends. The depth of the positioning groove is greater than the outer diameter of the positioning bolt. The positioning groove cooperates with the positioning bolt. The angle between the positioning plate and the inclined pull plate is in the range of 105°-145°.

[0014] Furthermore, two mating pieces are stacked on top of each other at the bottom of the positioning piece. The top of the upper mating piece is welded to the bottom of the positioning piece, and the bottom of the lower mating piece is welded to the top of the card seat. Guide clips are fixed on the front and rear sides of the mating pieces. The two guide clips are a pair. The inner sides of the two pairs of guide clips are movably sleeved with the outer sides of the two mating pieces, respectively. The opposite sides of the two guide clips are movably connected to the front and rear ends of the eccentric column, respectively. A pressure plate is fixed on the top of the eccentric column, and the bottom of the eccentric column abuts against the outer side of the mating piece.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This utility model provides a clamping device to reduce glass sway. The positioning hole cooperates with the positioning bolt to change the assembly position of the positioning piece below the upper crossbar, so that the user can adjust the installation position of the positioning piece according to the width of the glass substrate and the number of clamps. The positioning piece, the inclined pull piece and the card seat cooperate to limit the clamping treatment of the glass substrate from the top. The design combination of the card seat and the protective pad can improve the clamping stability of the card seat on the glass substrate.

[0018] This utility model provides a clamping device to reduce glass wobbling. In the process of magnetron sputtering coating of glass substrate held by the card holder and protective pad, the positioning pin may become loose. The positioning groove is designed to be symmetrical with the center and the depth of the positioning groove is greater than the outer diameter of the positioning pin. Combined with the connection between the glass substrate and the card holder and other components, the positioning piece will not slide off on the front and back sides of the upper crossbar, and the positioning piece cannot be deflected off based on the loose positioning pin. This effectively avoids the positioning piece from falling off from below the upper crossbar and causing the glass to fall off.

[0035] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element; the terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] See attached document Figure 1-7 This utility model provides a clamping device to reduce glass sway, comprising the following structure:

[0039] Two brackets 1 are provided, with a lower crossbar 2 and an upper crossbar 3 fixedly connected to the bottom and top of the two brackets 1 respectively by bolts.

[0040] Positioning piece 4, with a diagonal pull piece 5 fixed at the bottom left and / or right end of the positioning piece 4, a card seat 6 fixed at the bottom of the diagonal pull piece 5, and a protective pad 61 fixed on the inner wall of the card slot of the card seat 6.

[0041] In this embodiment, the top of the lower crossbar 2 is detachably and equally spaced with multiple limiting clips 21, and the top center of the limiting clip 21 is engaged with the bottom of the glass substrate.

[0042] The lower crossbar 2 cooperates with the limiting frame to perform limiting clamping 21 on the bottom of the glass substrate being coated by magnetron sputtering using this device.

[0043] In this embodiment, the bottom of the upper crossbar 3 is provided with a plurality of positioning holes 31 at equal intervals, and the bottom of the upper crossbar 3 is threadedly connected with a positioning bolt 32, the top of which is threadedly connected to the positioning hole 31.

[0044] The positioning hole 31 cooperates with the positioning bolt 32 to change the assembly position of the positioning piece 4 below the upper crossbar 3, so that the user can adjust the installation position of the positioning piece 4 according to the width of the glass substrate and the number of clamps. The positioning piece 4, the inclined pull piece 5 and the clamping seat 6 cooperate to limit the clamping treatment of the glass substrate from the top. The design combination of the clamping seat 6 and the protective pad 61 can improve the clamping stability of the clamping seat 6 on the glass substrate.

[0045] When fixing glass substrates with a small width, if a combination of positioning piece 4 and a single inclined pull piece 5 is used, two positioning pieces 4 are required. Here, a component consisting of positioning piece 4 and two inclined pull pieces 5 can be used, which greatly improves the ease of use.

[0046] In this embodiment, positioning grooves 41 are symmetrically provided at the left and right ends of the positioning piece 4. The depth of the positioning groove 41 is greater than the outer diameter of the positioning bolt 32. The positioning groove 41 cooperates with the positioning bolt 32. The angle between the positioning piece 4 and the inclined pull piece 5 is in the range of 105°-145°.

[0047] During the magnetron sputtering coating process where the glass substrate is held between the card holder 6 and the protective pad 61, the positioning pin 32 may become loose. The positioning groove 41 is designed to be symmetrical with the center and its depth is greater than the outer diameter of the positioning pin 32. Combined with the connection between the glass substrate and components such as the card holder 6, the positioning piece 4 will not slide off on the front or back side of the upper crossbar 3. The positioning piece 4 also cannot deflect and fall off based on the loose positioning pin 32, effectively preventing the positioning piece 4 from falling off from below the upper crossbar 3 and causing the substrate to fall off.

[0048] In this embodiment, two docking pieces 7 are stacked on the bottom of the positioning piece 4. The top of the upper docking piece 7 is welded to the bottom of the positioning piece 4, and the bottom of the lower docking piece 7 is welded to the top of the card seat 6. Guide clips 71 are fixed on the front and rear sides of the docking piece 7. The two guide clips 71 are a pair. The inner sides of the two pairs of guide clips 71 are movably sleeved with the outer sides of the two docking pieces 7, respectively. The opposite sides of the two guide clips 71 are movably connected to the front and rear ends of the eccentric column 72, respectively. A pressure plate 73 is fixed on the top of the eccentric column 72, and the bottom of the eccentric column 72 abuts against the outer side of the docking piece 7.

[0049] When clamping glass substrates of different heights between the upper crossbar 3 and the lower crossbar 2 for magnetron sputtering coating, the pressure plate 73 and the eccentric column 72 can be used to adjust and lock the assembly position of the two mating pieces 7 between the guide clamps 71, thereby adjusting the working position of the clamping seat 6 below the upper crossbar 3. This makes it convenient for users to clamp glass substrates of different heights between the lower crossbar 2 and the upper crossbar 3, improving the convenience of clamping glass substrates in this device.

[0050] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
