Description

Technical Field

[0001] The utility model relates to the field of lens fixtures, in particular to a lens loading fixture Background Art

[0002] At present, the traditional glass pieces (such as optical wave glass) are cleaned, inspected and shipped by protective film. The product processing flow is complicated, and the inspection requires double-sided film replacement inspection. At the same time, there is interference of the protective film on the inspection, after shipment.

[0003] The protective film method is to coat an adhesive layer on a supporting plate (such as a plastic sheet), and then place the split or processed glass pieces (the processed product is a lens) on the adhesive layer to achieve material transfer.

[0004] When the lenses are produced and sent to the client, if they are left for a long time, they are prone to lens contamination, and generally need to be cleaned later to meet the predetermined production or assembly requirements. Therefore, in actual production, it is necessary to clean the A and B surfaces of the lenses to meet their usage requirements. Therefore, the process is long and the cleaning requirements of the client (especially the adhesive layer) are not met.

[0005] For example, the specific steps (production side) include: lens - side A - brushing - drying - side B (in contact with the adhesive layer) - brushing - drying - inspection of side B - film replacement - inspection of side A - coating - shipment;

[0006] Traditional rework process (when the client has been left for a long time): brush A side - spin dry - inspect AB side inverted film brush - spin wash - spin dry - inspect B.

[0007] The existing adhesive type requires a turning process and needs to be cleaned separately. Utility Model Content

[0008] The main purpose of the utility model is to propose a lens loading jig, aiming to design a jig that is convenient for positioning the lens, while reducing the steps of turning over, facilitating the cleaning of the lens, and improving production efficiency.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a lens loading fixture, comprising:

[0010] A main body, wherein the main body is provided with through grooves arranged vertically and horizontally, and the through grooves are rectangular;

[0011] A limiting part, the limiting part is arranged on the upper wall of the main body, the limiting part is arranged in a bent shape, the limiting part is provided with a corner end of the through groove, and a spacing is provided between the inner side wall of the limiting part and the outer peripheral side of the through groove, and the upper wall of the main body is located at the position of the spacing to form a supporting frame;

[0012] The avoidance groove is provided at the corner end of the supporting frame and extends from the through groove to the limiting part.

[0013] In actual production, the lens can be directly placed on the upper wall of the supporting frame. The outer peripheral wall of the lens is positioned by the inner peripheral wall of the limiting part, effectively avoiding breakage caused by lens displacement. At the same time, through the settings of the through groove and the avoidance groove (to avoid liquid residue), the lens can be directly cleaned and dried in the jig (also called the tray), reducing the turning-over step of the jig, and the structure is simple and stable.

[0028] As Figures 1 to 5 shown, a lens loading fixture includes:

[0029] A main body 1, the main body 1 is provided with through grooves 10 arranged vertically and horizontally, and the through grooves 10 are rectangular in shape;

[0030] A limiting part 2, the limiting part 2 is arranged on the upper wall of the main body 1, the limiting part 2 is arranged in a bent shape, the limiting part 2 is provided with a corner end of the through groove 10, and there is a distance between the inner side wall of the limiting part 2 and the outer peripheral side of the through groove 10. A supporting frame 20 is formed at the position of the upper wall of the main body 1 where the distance is located;

[0031] An avoidance groove 3, the avoidance groove 3 is arranged at the corner end of the supporting frame 20 and extends from the through groove 10 to the limiting part 2.

[0032] In actual production, the lens can be directly placed on the upper wall of the supporting frame 20. Among them, the outer peripheral wall of the lens is positioned by the inner peripheral wall of the limiting part 2, effectively avoiding breakage caused by the displacement of the lens. At the same time, through the settings of the through groove 10 and the avoidance groove 3 (to avoid the residue of liquid), the lens can be directly cleaned and dried in the fixture (also called a tray), reducing the turning-over steps of the fixture, and the structure is simple and stable.

[0033] A positioning groove 41 is provided between the ends of two adjacent limiting parts 2, and a positioning part 42 matched with the positioning groove 41 is provided on the lower wall of the main body 1. The positioning part 42 protrudes from the lower wall of the main body 1, thereby realizing the stacking of the jigs. When the positioning part 42 and the positioning groove 41 are stacked, a positioning interval suitable for the thickness of the lens can be formed between the upper wall of the positioning groove 41 and the lower wall of the positioning part 42, thereby realizing the positioning of the lens in the vertical direction.

[0034] Specifically, the inner peripheral wall of the through groove 10 is gradually enlarged in diameter from top to bottom, so that the drainage can be carried out quickly, avoiding the residue of liquid, and facilitating the drying by centrifugation. At the same time, it is convenient for the forming and demolding of the jig, reducing the production deformation of the jig.

[0035] In the embodiment of the present invention, the limiting part 2 is gradually enlarged in diameter from bottom to top. (It can play a guiding role for the lens, realize the stable placement of the lens, and at the same time facilitate the integral forming and demolding of the jig.)

[0036] Specifically, the inclination of the through groove 10 is less than 5 degrees.

[0037] Specifically, the inclination of the limiting part 2 is greater than 5 degrees.

[0038] In the embodiment of the present invention, the main body 1 is integrally injection-molded from PC material. The jig material is required to be anti-static, with a surface resistance of 109 / ~1011 / Ω, resistant to baking at 65°C / 2H without deformation, resistant to cleaning with alkaline detergent (PH = 12), and preferably black for convenient automatic identification by the manipulator. The tray is tested for loading adaptability (no jamming of products, no dropping, no skewing).

[0039] Specifically, an avoidance space 51 is provided on the outer peripheral wall of the main body 1, and a convex eaves 52 matched with the avoidance space 51 is provided on the lower peripheral wall of the main body 1. When two main bodies 1 are stacked on each other, the convex eaves are clamped in the avoidance space 51, realizing the stacking of the jigs.

[0040] In the embodiment of the present invention, the positioning groove 41 extends vertically to the upper wall of the supporting frame 20.

[0041] The production process using this jig: cutting the lens - arranging the pieces (i.e., placing them on the jig) - cleaning - drying by centrifugation - inspecting the A and B surfaces - shipping;

[0042] Optimized rework process: directly cleaning - inspecting A and B.

[0043] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
