Description

Technical Field

[0001] This utility model belongs to the field of jig technology, and in particular relates to a lens coating jig. Background Technology

[0002] During the lens coating process, to ensure uniform coating thickness and material distribution, and to process multiple lenses simultaneously to improve production efficiency, the lenses must be placed on a specialized fixture. The fixture's function is to achieve precise lens positioning, thereby improving operational efficiency and product quality.

[0003] Traditional lens coating fixture designs often involve creating perforations in a support plate and placing support sections on opposite sides of the perforations to support the lens. However, such fixtures lack positioning structures, resulting in unstable lenses that are prone to detachment, scratches, or damage during the coating process due to vibration or mechanical forces, thus affecting coating quality and efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a lens coating fixture to address the aforementioned technical problems, thereby solving the issues raised in the background art.

[0005] In view of this, the present invention provides a lens coating fixture, wherein the carrier plate has perforations for lens mounting;

[0006] The support portion is located at the edge of the perforation and is used to support the lens;

[0007] A stop unit is provided on a support plate. The stop unit includes a stop member having a stop top for elastically stopping the lens.

[0008] Furthermore, the above technical solution also includes:

[0009] The support plate also has a groove with a through hole, and the abutment is provided on the groove;

[0010] The top abutment is provided on the top abutment component;

[0011] When the abutment is in the abutting position, the abutment head protrudes into the perforation and provides abutting force against the lens. When the abutment is in the retracted position, the abutment head disengages from the lens.

[0012] In the above technical solution, the support plate further has a sliding groove connecting the perforation and the groove, and the top of the abutment is slidably disposed on the sliding groove.

[0013] In the above technical solution, the abutting member further includes a base that connects to the abutting top and is located within the groove, and the base has a levering part that protrudes from the groove.

[0014] In the above technical solution, the abutting unit further includes an elastic element, which has a first elastic portion of the abutting groove and a second elastic portion that abuts against the base.

[0015] In the above technical solution, a first groove is provided on the groove portion, a second groove corresponding to the first groove is provided on the base of the abutment member, a first elastic portion of the elastic element is provided in the first groove, and a second elastic portion of the elastic element is provided in the second groove.

[0016] In the above technical solution, a pressure strip is further provided at the upper end of the groove. The pressure strip is used to restrict the top of the abutting member from slipping out of the groove and to allow the abutting member to be abutted by the lever when it is in the abutting position.

[0017] In the above technical solution, the pressure strip is further secured to the groove of the bearing plate by screws.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By using the elastic abutment of the abutment to apply pre-pressure to the lens, it is firmly positioned on the carrier plate. This design can prevent the lens from falling off, scratching or being damaged due to vibration or mechanical force during the coating process, thereby significantly improving the coating quality and efficiency.

[0020] 2. The first elastic part of each elastic element is provided in the first groove of the bearing plate, and the second elastic part of each elastic element is provided in the second groove of the abutment member, so as to provide the abutment member with elastic preload for abutting the lens.

[0068] Working principle: When the lens 10 is coated, the abutment 30 is first moved in the opposite direction of the perforation 21, so that the abutment 30 is in the retracted position and its top 30 is retracted and not inside the perforation 21. At the same time, it presses against each elastic element 40. Then, the lens 10 is placed in the perforation 21, and the long edges of the two sides of the coated surface 11 of the lens 10 rest against the support part 22 of the perforation 21. Then, the abutment 30 is released, so that it is pushed in the direction of the perforation 21 by the elastic restoring force of the elastic element 40 and moves from the retracted position to the abutment position. At this time, the abutment 30 is affected by the elastic force of the elastic element 40, so that its top 30 protrudes into the perforation 21 and provides a top force to abut against the lens 10. Finally, the lens 10 is stably positioned on the support plate 20, which prevents the lens from falling off, scratching or being damaged due to vibration or mechanical force during the coating process, thereby significantly improving the coating quality and efficiency.
