Description

Technical Field

[0001] This utility model relates to the field of lens processing equipment, and in particular to a combined bonding fixture for lens processing. Background Technology

[0002] In the lens assembly and bonding industry, a diaphragm and high-temperature adhesive are typically used to bond lenses.

[0003] Its operation is complex, and its process includes:

[0004] 1. Fix the diaphragm on the carrier, manually (or mechanically) apply high-temperature tape in strips according to the diaphragm's texture (e.g., grooves), and use a blade to cut the high-temperature tape;

[0005] 2. Remove the protective film (high-temperature tape includes the adhesive layer and the protective film) and use the sticky side to adhere the bracket (lens bracket). Finally, install the lens in the next process.

[0006] Therefore, high-temperature tape has a short service life, easily attracts dust and dirt, and requires frequent replacement and cleaning. Utility Model Content

[0007] The main purpose of this invention is to propose a combined bonding fixture for lens processing, which aims to optimize the work process and save on the cost of high-temperature adhesive tape through the improved fixture; at the same time, it is easy to clean.

[0008] To achieve the above objectives, this utility model proposes a combined bonding fixture for lens processing, comprising:

[0009] The tray is provided with a clearance groove recessed from its upper wall;

[0010] A positioning groove, which is used to place a lens holder, is recessed in the upper wall of the positioning groove and is distributed in an array;

[0011] The positioning groove is rectangular in shape;

[0012] The corner end of the positioning groove is provided with an outwardly extending groove.

[0013] The upper wall of the positioning groove is provided with a vacuum hole that penetrates the wall of the tray.

[0014] The improved tray reduces the need for adhesive tape application and cleaning. A robotic arm directly places the lens holder into the positioning slot. When further positioning is required, the tray is placed on a vacuum device, where negative pressure is applied to the lower end of the vacuum port, stabilizing the lens holder in the positioning slot. The lens is then attached, and finally, the tray is placed in a high-temperature baking oven to bond the lens and holder. After use, the tray can be cleaned with alcohol. The structure is simple, stable, and easy for automated equipment to handle. Attached Figure Description

[0030] like Figures 1 to 5 As shown, a combined bonding fixture for lens processing includes:

[0031] The tray 1 is provided with a relief groove 10 recessed from its upper wall;

[0032] Positioning groove 2, the positioning groove 2 is used to place the lens holder, the positioning groove 2 is recessed in the upper wall and distributed in an array;

[0033] The positioning groove 2 is rectangular in shape;

[0034] The corner end of the positioning groove 2 is provided with an outwardly extending groove position 2a;

[0035] The upper wall of the positioning groove 2 is provided with a vacuum hole 2b that penetrates the wall of the tray 1.

[0036] The improved tray 1 reduces the previous adhesive tape application process and eliminates the need for cleaning. A robotic arm directly places the lens holder into the positioning groove 2. When further positioning is required, the tray 1 is placed on a vacuum device, and negative pressure is applied to the lower end of the vacuum hole 2b, thus stabilizing the lens holder in the positioning groove 2. The lens is then attached, and finally, the tray is placed in a high-temperature baking oven to bond the lens and holder. After use, the tray 1 can be cleaned with alcohol. The structure is simple, stable, and convenient for automated equipment to handle.

[0037] Specifically, the positioning groove 2 is rectangular or square in shape, and can be set according to different shapes of the lens holder.

[0038] In this embodiment of the invention, the groove 2a is elliptical or circular in shape. This shape is easy to process; a hole can be directly formed using a CNC drill bit, effectively reducing production difficulty.

[0039] Specifically, the lower wall of the tray 1 is provided with longitudinally and transversely arranged adsorption channels 3, and the adsorption channels 3 are interconnected. The lower end of the vacuum hole 2b is located inside the adsorption channel 3. Through the interconnected adsorption channels 3, when the tray 1 is placed in the vacuum equipment, negative pressure can be applied to all positioning slots 2, thereby achieving adsorption of all lens holders.

[0040] In this embodiment of the utility model, at least two sides of the upper wall of the positioning groove 2 are provided with gap grooves 4 that are connected to each other. The gap grooves 4 are arranged adjacent to the inner peripheral wall of the positioning groove 2, such as... Figure 4 (Non-overlapping state). In the actual design, the vacuum hole 2b is directly adsorbed to the lens holder. When the lens is removed, an adsorption force will be formed between the vacuum hole 2b and the lens, which will cause the lens to get stuck when it is removed, especially in automated machinery. Therefore, in another design, the gap groove 4 and the vacuum hole 2b partially overlap, which facilitates the lens clamping and also ensures the stability of the adsorption.

[0041] Specifically, the gap groove 4 portion is connected to the vacuum hole 2b, as follows: Figure 3 .

[0042] In this embodiment of the utility model, the groove position 2a is provided through or recessed in the positioning groove 2, which can be set according to actual needs, thereby facilitating the clamping of the bracket.

[0043] Specifically, the upper wall of the positioning groove 2 has at least two inclined surfaces 5 on both sides, which serve as guides to facilitate the placement of the bracket.

[0044] In this embodiment of the utility model, at least two corner ends of the tray 1 are provided with chamfered corners 6, thereby achieving the function of alignment and facilitating placement on the vacuum device.

[0045] Specifically, the tray 1 is made of lead-aluminum alloy, which has low hardness and is easy to process.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
