Description

Technical Field

[0001] This utility model relates to the field of optical component bonding technology, and in particular to a bonding fixture. Background Technology

[0002] In optical bonding, it is often necessary to assemble different optical components. When different optical components need to be aligned, traditional optical fixtures (i.e., bonding jigs) often adopt a right-angle structure, placing the optical components on a horizontal platform and aligning them by the two ends of the right-angle fixture. Because the glue used for bonding is fluid, the optical components will become misaligned during curing, resulting in dimensional and other tolerances not meeting the requirements. In addition, when aligning the sides with glue, when the glue overflows and cures, it becomes a whole with the optical fixture, making it difficult or impossible to remove the optical components. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a gluing fixture that prevents the glued parts from becoming misaligned due to the flow of glue, and avoids glue overflow from solidifying the glued parts and the support body into one piece, making them impossible to separate.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A gluing fixture includes a base plate and two limiting plates. The base plate is square, and the two limiting plates are respectively vertically disposed on adjacent end edges of one side of the base plate. The other adjacent end edges of one side of the base plate are respectively provided with positioning grooves. Both positioning grooves are used to insert fixing blocks. The two limiting plates and the two fixing blocks form an accommodating space for accommodating optical gluing parts and fixing the optical gluing parts on four sides. A strip groove is provided through the limiting plate, and the strip groove is set corresponding to the glue overflow position of the optical gluing parts.

[0006] Furthermore, the vertical distance between the bottom of the strip groove and one side of the base plate is less than the vertical distance between the overflow position of the optical adhesive and one side of the base plate.

[0007] Furthermore, the vertical distance between the top of the strip groove and one side of the base plate is greater than the vertical distance between the overflow position of the optical adhesive and one side of the base plate, but less than the height of the optical adhesive placed on one side of the base plate.

[0008] Furthermore, the optical adhesive component is square, and the positioning groove is located at the center of the side length of the optical adhesive component.

[0009] Furthermore, the optical adhesive component is circular, and the positioning groove is set at the tangent point between the limiting plate at its opposite end and the optical adhesive component.

[0010] Furthermore, the height of the fixing block protruding from one side of the base plate after being inserted into the positioning groove is greater than the vertical distance between the overflow position of the optical adhesive and one side of the base plate.

[0011] Furthermore, the two limiting plates are connected to each other.

[0012] Furthermore, the bottom surface of the optical adhesive is a planar structure.

[0013] Furthermore, the optical adhesive comprises two optical elements bonded together.

[0014] Furthermore, the optical element is a lens.

[0015] The beneficial effects of this utility model are as follows:

[0016] This solution involves vertically positioning two limiting plates at adjacent ends on one side of the base plate, with positioning grooves at the other adjacent ends on the same side of the base plate. Both positioning grooves are used to insert fixing blocks. The two limiting plates and two fixing blocks form an accommodating space for the optical adhesive component and fix it on all four sides. This ensures that the adhesive component does not move and is not misaligned due to glue flow. Furthermore, a strip groove is cut through the limiting plates, corresponding to the glue overflow position of the optical adhesive component. This prevents the glue overflow from curing the adhesive component and the backing (i.e., the two limiting plates) into one piece, making them inseparable. Attached Figure Description

[0021] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figure 1 as well as Figure 2A gluing fixture includes a base plate and two limiting plates. The base plate is square. The two limiting plates are respectively vertically disposed on adjacent ends of one side of the base plate. The other adjacent ends of one side of the base plate are respectively provided with positioning grooves. Both positioning grooves are used to insert fixing blocks. The two limiting plates and the two fixing blocks form an accommodating space for accommodating optical gluing parts and respectively fix the optical gluing parts on four sides. A strip groove is provided through the limiting plate, and the strip groove is set corresponding to the glue overflow position of the optical gluing parts.

[0023] As can be seen from the above description, the beneficial effects of this utility model are as follows:

[0024] This solution involves vertically positioning two limiting plates at adjacent ends on one side of the base plate, with positioning grooves at the other adjacent ends on the same side of the base plate. Both positioning grooves are used to insert fixing blocks. The two limiting plates and two fixing blocks form an accommodating space for the optical adhesive component and fix it on all four sides. This ensures that the adhesive component does not move and is not misaligned due to glue flow. Furthermore, a strip groove is cut through the limiting plates, corresponding to the glue overflow position of the optical adhesive component. This prevents the glue overflow from curing the adhesive component and the backing (i.e., the two limiting plates) into one piece, making them inseparable.

[0025] Furthermore, the vertical distance between the bottom of the strip groove and one side of the base plate is less than the vertical distance between the overflow position of the optical adhesive and one side of the base plate.

[0026] As can be seen from the above description, by setting the above structure, it is possible to ensure that the lower limit part of the limiting plate fixes the glued parts to prevent them from moving, while also facilitating the discharge of excess glue from the glued parts. This avoids the glue overflow from solidifying the glued parts and the backing body (i.e., the two limiting plates) into one piece, making them impossible to separate.

[0027] Furthermore, the vertical distance between the top of the strip groove and one side of the base plate is greater than the vertical distance between the overflow position of the optical adhesive and one side of the base plate, but less than the height of the optical adhesive placed on one side of the base plate.

[0028] As can be seen from the above description, by setting the above structure, it is possible to ensure that the upper limit part of the limiting plate fixes the glued parts, while also facilitating the discharge of glue overflow from the glued parts. This prevents the glue overflow from solidifying the glued parts and the backing body (i.e., the two limiting plates) into one piece, making them impossible to separate.

[0029] Furthermore, the optical adhesive component is square, and the positioning groove is located at the center of the side length of the optical adhesive component.

[0030] Furthermore, the optical adhesive component is circular, and the positioning groove is set at the tangent point between the limiting plate at its opposite end and the optical adhesive component.

[0031] Furthermore, the height of the fixing block protruding from one side of the base plate after being inserted into the positioning groove is greater than the vertical distance between the overflow position of the optical adhesive and one side of the base plate.

[0032] As can be seen from the above description, by setting the above structure, the optical adhesive parts can be better fixed to prevent them from moving and to prevent them from becoming misaligned due to the flow of adhesive.

[0033] Furthermore, the two limiting plates are connected to each other.

[0034] Furthermore, the bottom surface of the optical adhesive is a planar structure.

[0035] Furthermore, the optical adhesive comprises two optical elements bonded together.

[0036] Furthermore, the optical element is a lens.

[0037] Please refer to Figure 1 and Figure 2 As shown, Embodiment 1 of this utility model is as follows:

[0038] Please refer to Figure 1 and Figure 2 A bonding fixture includes a base plate 1 and two limiting plates 2. The base plate 1 is square. The two limiting plates 2 are respectively vertically arranged on the adjacent two ends of one side of the base plate 1. The other adjacent two ends of one side of the base plate 1 are respectively provided with positioning grooves 11. Both positioning grooves 11 are used to insert fixing blocks 3. The two limiting plates 2 and the two fixing blocks 3 form an accommodating space for accommodating optical bonding parts 4 and fixing the optical bonding parts 4 on all four sides. A strip groove 21 is provided through the limiting plate 2. The strip groove 21 is provided corresponding to the glue overflow position 41 of the optical bonding parts 4.

[0039] Please refer to Figure 1 and Figure 2 The two limiting plates 2 are connected to each other.

[0040] Please refer to Figure 1 The bottom surface of the optical adhesive 4 is a planar structure.

[0041] Please refer to Figure 1 The optical adhesive 4 includes two optical elements 42 glued together.

[0042] The optical element 42 is a lens.

[0043] Please refer to Figure 1The vertical distance between the bottom of the strip groove 21 and one side of the base plate 1 is less than the vertical distance between the overflow glue position 41 of the optical adhesive 4 and one side of the base plate 1.

[0044] Please refer to Figure 1 The vertical distance between the top of the strip groove 21 and one side of the base plate 1 is greater than the vertical distance between the overflow position 41 of the optical adhesive 4 and one side of the base plate 1 and less than the height of the optical adhesive 4 placed on one side of the base plate 1.

[0045] For example, in this embodiment, the two optical elements 42 that need to be glued are both optical elements 42 with a thickness of 5mm. Thus, the vertical distance between the bottom of the strip groove 21 and one side of the base plate 1 is 1mm-2mm (as long as it can hold the lower optical element 42). The groove height of the strip groove 21 is 5mm. Thus, the vertical distance between the top of the strip groove 21 and one side of the base plate 1 is 6mm-7mm. The distance between the top of the limiting plate 2 and the top of the strip groove 21 must be greater than or equal to 2mm to hold the upper optical element 42.

[0046] The optical adhesive 4 is square (it can be rectangular or square), and the positioning groove 11 is located at the center of the side length of the optical adhesive 4.

[0047] The optical adhesive component 4 is circular, and the positioning groove 11 is set at the tangent point between the limiting plate 2 and the optical adhesive component 4 at its opposite end.

[0048] After the fixing block 3 is inserted into the positioning groove 11, the height of the protrusion of the bottom plate 1 is greater than the vertical distance between the overflow position 41 of the optical adhesive 4 and the bottom plate 1.

[0049] The length of the groove 21 only needs to avoid the overflow of glue at the glue overflow position 41 of the optical adhesive 4. For example, for an optical adhesive 4 with a diameter of 50mm (taking the optical adhesive 4 as a circle as an example), the length of the groove 21 is 10mm, which can basically avoid the overflow of glue.

[0050] The gluing fixture involved in this solution firstly controls the amount of glue used when gluing the two optical elements 42 to prevent excessive glue overflow. Before positioning, the excess glue is wiped off. During the movement of the optical elements 42 after wiping, misalignment will occur, and new glue will be discharged. In this system, if a small amount of glue overflows after the optical elements 42 are positioned, there is no need to wipe it off. The overflowing glue will be discharged from the groove 21, thus avoiding contact between the optical elements 42 and the support (i.e., the two limiting plates 2), preventing them from curing into one piece and thus avoiding the problem of being unable to separate. Secondly, for the excess glue, since the groove 21 is provided, a cotton swab can be used to wipe it off. Furthermore, if too much glue overflows to the bottom, it can be prevented by applying matte varnish to the bottom of the optical elements 42 beforehand.

[0051] In summary, the gluing fixture provided by this utility model consists of two limiting plates vertically positioned at adjacent ends on one side of a base plate, and positioning grooves at the other adjacent ends on the same side of the base plate. Both positioning grooves are used to insert fixing blocks. The two limiting plates and the two fixing blocks form an accommodating space for accommodating the optical gluing component and fix the optical gluing component on all four sides. This ensures that the gluing component does not move and does not become misaligned due to glue flow. Furthermore, a strip groove is provided through the limiting plate, corresponding to the glue overflow position of the optical gluing component. This prevents the glue overflow from curing the gluing component and the support (i.e., the two limiting plates) into one piece, making them inseparable.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
