Description

Technical Field

[0001] The utility model relates to the technical field of lens clamps, and more specifically to a Glens coating loading clamp. Background Art

[0002] Glens is an optical self-focusing lens with an appearance of glass wire of about 1mm in diameter and 2mm in length. It requires double-sided coating. The current Glens product introduction and installation requirements are: When the Glens coating is fixed on the fixture, each lens is required to be on the same horizontal plane and firmly fixed, and there is no falling off during subsequent ultrasonic cleaning and coating.

[0003] However, in the existing IBS coating machine, when coating Glens products, the existing fixtures and products are mostly fixed by rigid extrusion. After the fixture is installed, each row of products is fixed by the edge tightening screws. In this process, if the tightening screws are too tight, it is easy to damage the product, and if they are too loose, they are easy to fall off during the subsequent cleaning and coating. In addition, after ultrasonic cleaning, the contact position between the product and the fixture is easily damaged, thereby reducing the yield rate. Therefore, this scheme proposes a Glens coating loading fixture. Utility Model Content

[0033] See also Figures 1 - 3 A Glens coating loading fixture comprises an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 have corresponding sides each with a groove 3, and a limiting notch is formed between the grooves 3 that are arranged in pairs. A clamping piece 1 4, a clamping piece 2 5, and a clamping piece 3 6 are arranged between the inner walls of the limiting notch. The side ends of the upper mold 1 and the lower mold 2 have mounting grooves 7, and a threaded through hole is formed between the mounting grooves 7 that are arranged in pairs. A stud 8 is threadedly connected between the inner walls of the threaded through hole.

[0034] More specifically, the clamping member 4 includes a clamping plate 41 disposed between the inner walls of the limiting groove, and a plurality of positioning holes 42 are formed at the right end of the clamping plate 41 .

[0035] More specifically: the clamping member 2 5 includes a clamping plate 2 51 provided between the inner walls of the limiting groove, a plurality of positioning holes 2 52 and a pre-tightening groove 1 53 are provided at the left end of the clamping plate 2 51, the pre-tightening groove 1 53 is located on the upper side of the positioning hole 2 52, and a plurality of positioning holes 3 54 are provided at the right end of the clamping plate 2 51.

[0036] More specifically, the clamping member 3 6 includes a clamping plate 3 61 provided between the inner walls of the limiting grooves, and a plurality of positioning holes 4 62 and pre-tightening grooves 2 63 are provided at the left end of the clamping plate 3 61 , and the pre-tightening grooves 2 63 are located on the upper side of the positioning holes 4 62 .

[0037] More specifically, the upper mold 1, the lower mold 2, the clamping piece 1 4, the clamping piece 2 5, and the clamping piece 3 6 are all made of spring steel material, and the stud 8 is made of copper material.

[0038] During use of this solution, the clamping piece 1 4, the clamping piece 2 5, and the clamping piece 3 6 are pre-placed in the limiting grooves formed by the upper mold 1 and the lower mold 2 before extrusion molding. When no clamping is required, the clamping piece 1 4, the clamping piece 2 5, and the clamping piece 3 6 can slide freely between the limiting grooves;

[0039] When re-clamping is required, the personnel rotate the stud 8 to cause one side of the stud 8 to continuously contact the clamping piece 3 6 inside the upper mold 1 and the lower mold 2 through the lines on the inner wall of the installation groove 7, until the clamping piece 1 4, the clamping piece 2 5, and the clamping piece 3 6 are limited by the interference and cannot continue to slide. Then the personnel clamp the Glens coating, and penetrate the Glens coating with a bolt made of copper material and connect it with the connecting holes formed between the positioning hole 1 42, the positioning hole 2 52 and the positioning hole 2 52, the positioning hole 3 54, and the positioning hole 3 54, the positioning hole 4 62, so as to ensure the verticality of each product after clamping and improve the consistency of the coating;

[0040] And during the fixing period, since a pre-tightening groove 53 and a pre-tightening groove 63 are respectively formed on one side of the positioning hole two 52 and the positioning hole four 62, when the bolt is connected to the interior, it has a certain pre-tightening force and elastic performance, which not only ensures the fixing strength during the clamping of the fixture, but also avoids the phenomenon that the product is damaged due to excessive clamping force, making it not easy to be detached due to too small clamping force or damaged under ultrasonic vibration due to too large clamping force during the subsequent ultrasonic cleaning process, greatly ensuring the yield rate of the Glens product during the subsequent plating process.

[0041] The above-described embodiments merely represent certain implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
