Description

Technical Field

[0001] This application relates to the field of optical component assembly technology, specifically to a thin glass bonding fixture. Background Technology

[0002] In the field of precision optics, to achieve complex optical performance or integrate multiple functions, it is often necessary to bond microcrystalline glass to specific areas of a workpiece to achieve specific functions. To ensure the reliability of the finished workpiece, extremely high precision is required for the bonding position. In existing technologies, bonding thin glass sheets is a major technological challenge. This is because thin microcrystalline glass sheets are prone to deformation and bending, and existing clamping fixtures struggle to control the clamping force, easily causing glass breakage. Furthermore, the bonding process requires adjusting the position of the microcrystalline glass sheet to ensure accuracy. After bonding, the fixture must be removed without damaging the bonded microcrystalline glass sheet or affecting the adhesion between the glass sheet and the target workpiece. Therefore, a new thin glass bonding fixture is needed to overcome these challenges. Utility Model Content

[0003] The purpose of this application is to provide a thin glass bonding fixture that improves the positional accuracy and efficiency of thin glass bonding without damaging the thin glass.

[0004] To achieve the above objectives, this application provides a thin-film glass bonding fixture for bonding a target thin-film glass to a target bonding area of ​​a target workpiece. The fixture includes a negative pressure adsorption component, a position adjustment component, a connector, a positioning piece, a fixing component, and a glass fixing plate adapted to the target workpiece. One side panel of the glass fixing plate has a glass fixing area with multiple rows of through holes. The other side panel of the glass fixing plate has negative pressure holes communicating with the through holes. These negative pressure holes connect to the negative pressure adsorption component, which provides negative pressure to the glass fixing area. The position adjustment component is connected to the glass fixing plate via the connector and adjusts the position of the target thin-film glass to the target bonding area. The positioning piece is positioned on the glass fixing plate near the glass fixing area. The fixing component is positioned around the glass fixing plate to fix it in place.

[0005] In this embodiment, the position adjustment component includes a six-dimensional platform, the connector includes a connecting column, the glass fixing plate is provided with a connecting hole adapted to the connecting column, one end of the connecting column is connected to the glass fixing plate through the connecting hole, and the other end is fixedly connected to the loading platform of the six-dimensional platform through a lead screw.

[0006] In this embodiment of the application, the thin glass bonding fixture further includes a metal connector fixedly connected to the negative pressure hole, and the metal connector is used to connect the negative pressure adsorption assembly.

[0007] In this embodiment of the application, the negative pressure adsorption component includes: an adjustable vacuum pump, a vacuum pipe connecting the adjustable vacuum pump and a metal connector, and a vacuum valve disposed on the vacuum pipe for controlling the opening and closing of the vacuum pipe; the vacuum pipe is a corrugated metal pipe.

[0008] In this embodiment of the application, the thin glass bonding fixture further includes a handle, and the glass fixing plate is provided with fixing holes for fixing the handle.

[0009] In this embodiment of the application, the fixing component includes a plurality of fixing members, any one of the fixing members abuts against the glass fixing plate, and the glass fixing plate has at least one pair of opposing sidewalls provided with the fixing members.

[0010] In this embodiment, the through holes in the glass fixing area are evenly arranged.

[0011] In this embodiment, all through holes have the same diameter, and the diameter of any through hole is 1 / 18 to 1 / 17 of the width of the target bonding area.

[0012] In this embodiment, the glass fixing plate is made of transparent glass. The solution provided by this application has at least the following beneficial effects:

[0013] The thin glass bonding fixture provided in this application improves bonding efficiency by pre-determining a precisely positioned glass fixing area on the glass fixing plate and setting fasteners and positioning pieces near the glass fixing area, enabling the target thin glass sheet to be quickly and accurately fixed in the desired area. Furthermore, by fixing the glass fixing plate to the position adjustment component, precise alignment between the target thin glass sheet and the target bonding area can be achieved. After bonding, simply removing the negative pressure adsorption component releases the negative pressure in the glass fixing area, allowing the target thin glass sheet to separate from the glass fixing plate without damage. The thin glass bonding fixture provided in this application has a simple structure, low manufacturing cost, and is easy to use.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a thin glass bonding fixture, which is used to bond a target thin glass sheet to a target bonding area 101 of a target workpiece 100. The thin glass bonding fixture includes a negative pressure adsorption component, a position adjustment component, a connector, a positioning piece 2, a fixing component, and a glass fixing plate 1 adapted to the target workpiece 100. One side panel of the glass fixing plate 1 is provided with a glass fixing area 11, and the glass fixing area 11 is provided with multiple rows of through holes 12. The other side panel of the glass fixing plate 1 is provided with a negative pressure hole communicating with the through holes 12. The negative pressure hole is used to connect the negative pressure adsorption component, and the negative pressure adsorption component is used to provide negative pressure to the glass fixing area 11. That is, in this embodiment, the negative pressure hole is located on the back of the glass fixing area 11, which can shorten the channel distance between the through holes 12 and the negative pressure hole, and ensure that the negative pressure adsorption component can provide stable negative pressure to the glass fixing area 11.

[0028] The method for bonding thin glass sheets provided in this embodiment is as follows: First, the target thin glass sheet is fixed on the glass fixing plate 1. Then, the glass fixing plate 1 is moved to align the target thin glass sheet with the target bonding area 101 of the target workpiece 100. After bonding, the target thin glass sheet and the glass fixing plate 1 are separated. There are two main difficulties in the above process: first, achieving the connection and separation between the target thin glass sheet and the glass fixing plate 1 while ensuring no damage to the target thin glass sheet; and second, aligning the target thin glass sheet with the target bonding area 101.

[0029] Regarding the first point, in this embodiment, a negative pressure adsorption component is used to provide negative pressure to the glass fixing area 11 of the glass fixing plate 1 to achieve the effect of adsorbing and fixing the target thin glass sheet. After the target thin glass sheet is bonded, the negative pressure adsorption component is removed, allowing the glass fixing area 11 to return to normal pressure, thus releasing the adsorption connection. During this process, no damage will be caused to the already bonded thin microcrystalline glass sheet, and the bonding effect between the target thin glass sheet and the target workpiece 100 will not be affected. Specifically, in order to ensure that the target thin glass sheet does not warp or deform during adsorption, in this embodiment, in addition to controlling the output power of the negative pressure adsorption component, the size and arrangement of the through holes 12 in the glass fixing area 11 are also reasonably designed according to the size of the target thin glass sheet.

[0030] like Figure 1 As shown, any row of through holes 12 within the glass fixing area 11 is evenly spaced, and all through holes 12 have the same diameter. With the centerline along the length of the glass fixing area 11 as the axis, multiple rows of through holes 12 are mirror-symmetrical (this only applies when the target thin glass sheet has a uniform thickness; if the target thin glass sheet has an uneven thickness, adaptive adjustments are needed, such as making the diameter of the through holes at the corresponding position on the thick side of the target thin glass sheet larger than the diameter of the through holes at the corresponding position on the thin side, or making the through hole density at the corresponding position on the thick side greater than the through hole density at the corresponding position on the thin side). For example, the diameter of any through hole 12 is 1 / 18 to 1 / 17 of the width of the target bonding area 101. Experiments have shown that through holes 12 with diameters within this range can firmly adhere to the target thin glass sheet without causing bending deformation or leaving hole marks.

[0031] Regarding the second point, in this embodiment, the glass fixing plate 1 is connected to the position adjustment component. The precise positioning capability of the position adjustment component is used to adjust the position of the glass fixing plate 1 (target thin glass sheet) to ensure the bonding position accuracy of the target thin glass sheet. For example, the position adjustment component is connected to the glass fixing plate 1 via the connector. The position adjustment component is used to adjust the position of the thin glass sheet to the target bonding area 101; the positioning piece 2 is disposed on the glass fixing plate 1 near the glass fixing area 11. Specifically, the position adjustment component can be a six-dimensional platform 3, and the connector includes a connecting post 4 (one end of which is adapted to the loading platform of the six-dimensional platform 3). The glass fixing plate 1 has a connecting hole 14 adapted to the connecting post 4 (the other end). One end of the connecting post 4 is connected to the glass fixing plate 1 through the connecting hole 14, and the other end is fixedly connected to the loading platform of the six-dimensional platform 3 via a screw rod. Figure 4 and Figure 5As shown. If the connecting hole 14 and the connecting post 4 are not compatible, they can be fixed by embedding a suitable wedge to ensure that there is no relative displacement between the six-dimensional platform 3 and the glass fixing plate 1 during the process of the six-dimensional platform 3 driving the glass fixing plate 1 to move.

[0032] Furthermore, the thin glass bonding fixture also includes a metal connector 5 fixedly connected to the negative pressure hole. The metal connector 5 is used to connect the negative pressure adsorption component. The connection between the metal connector 5 and the negative pressure adsorption component can improve the stability of negative pressure delivery.

[0033] Specifically, the negative pressure adsorption assembly includes: an adjustable vacuum pump (with adjustable negative pressure to accommodate thin glass sheets of different thicknesses), a vacuum pipe connecting the adjustable vacuum pump and the metal connector 5, and a vacuum valve installed on the vacuum pipe for controlling the opening and closing of the vacuum pipe. In addition, since the glass fixing plate 1 needs to be moved during the process of bonding the target thin glass sheet to the target bonding area 101, and the glass fixing area 11 needs to be kept in an adsorption state at all times during this process, the pipe used to transport negative pressure is preferably able to extend and retract in all directions. Preferably, the vacuum pipe is a corrugated metal pipe, which can ensure the stable transport of negative pressure and prevent the pipe from deforming during the operation of the adjustable vacuum pump.

[0034] Furthermore, such as Figure 1 As shown, the fixing assembly includes multiple fixing members 6. Each fixing member 6 abuts against the glass fixing plate 1. The glass fixing plate 1 has at least one pair of opposing sidewalls with the fixing member 6 to ensure that the glass fixing plate 1 can be fixed and to prevent the glass fixing plate 1 from shifting during the placement of the target thin glass sheet, which would cause the target thin glass sheet to deviate in position (if the target thin glass sheet is deviated in position, it will further affect the alignment accuracy of the target thin glass sheet and the target bonding area 101).

[0035] Furthermore, such as Figure 2 As shown, the thin glass bonding fixture also includes a handle, and the glass fixing plate 1 has fixing holes 13 for fixing the handle. Specifically, the handle can be snapped into the fixing holes 13 (detachable connection), allowing the operator (or robotic arm, etc.) to easily move the glass fixing plate 1. Alternatively, without the handle installed, the operator can also use the fixing holes 13 as a leverage point to move the glass fixing plate 1.

[0036] Furthermore, in this embodiment, the glass fixing plate 1 is made of transparent glass. For example... Figure 4As shown, during the process of aligning the target thin glass sheet and the target bonding area 101, the side panel of the glass fixing plate 1 that fixes the target thin glass sheet is facing down. If the glass fixing plate 1 is made of non-transparent material, the bonding process will be in a blind spot throughout, and the operator will not be able to directly observe the bonding process, which may lead to the failure to detect potential hazards in a timely manner.

[0037] In addition, the following method can be used to determine the position of the glass fixing area 11 on the glass fixing plate 1: Create a thin-film model with the same specifications and dimensions as the target thin-film glass. Based on the position of the target bonding area 101 on the target workpiece 100, determine the position of the glass fixing area 11 (if there are multiple target bonding areas 101, pay attention to the positional relationship between them to ensure a one-to-one correspondence between the position of the glass fixing area 11 on the glass fixing plate 1 and the target bonding area 101). After determining the position on the glass fixing plate 1 using the thin-film model, attach the positioning piece 2 near the thin-film model, such as... Figure 1 As shown, if the glass fixing area 11 is located at the edge of the glass fixing plate 1, the fixing member 6 can be used to assist in positioning. When placing the target thin glass, it is only necessary to make the two adjacent side walls of the target thin glass abut against the positioning piece 2 and the fixing member 6 respectively.

[0038] The thin glass bonding fixture provided in this application has a simple structure and low manufacturing cost. It can bond the thin glass to the target bonding area 101 of the target workpiece 100 without damaging the thin glass, and can ensure extremely high positional accuracy. The thin glass bonding fixture pre-determines a precisely positioned glass fixing area 11 on the glass fixing plate 1, and sets fixing parts 6 and positioning pieces 2 near the glass fixing area 11. This ensures that when fixing the target thin glass, the target thin glass can quickly and accurately coincide with the position (glass fixing area 11) determined by the thin glass model, improving bonding efficiency. After fixing the target thin glass, the glass fixing plate 1 is moved to the area of ​​the target workpiece 100 that matches it, so as to... Figure 3 Taking the structure of the target workpiece 100 as an example, a six-dimensional platform 3, which is pre-set in the middle of the target workpiece 100, is fixedly connected to one end of a connecting column 4. The other end of the connecting column 4 passes through the connecting hole 14 in the middle of the glass fixing plate 1 and is fixedly connected to the glass fixing plate 1. A rectangular coordinate system is established with one right-angle vertex of the glass fixing plate 1 as the origin. The position coordinates of the target bonding area 101 (midpoint) and the current position coordinates of the target thin glass (midpoint) in the rectangular coordinate system are obtained. Based on the above position coordinates, the movement path of the target thin glass is determined, and the six-dimensional platform 3 drives the target thin glass to move according to the movement path.
