Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically to a vacuum bonding equipment for lens production. Background Technology

[0002] Vacuum bonding equipment is a key piece of equipment in lens manufacturing. It is mainly used to bond lenses with other materials (such as protective films) with high precision and without bubbles.

[0003] The working principle of most existing vacuum bonding equipment for lens production involves placing the lenses and other materials to be bonded on the bonding table and conveying them to the bottom of the pressure plate. A hydraulic system is activated, moving the vacuum chamber downwards to create a sealed environment. Air is then extracted from the vacuum chamber, creating a negative pressure environment. The heating device then activates, increasing the bonding temperature. Finally, the pressure plate descends, pressing the materials to be bonded together.

[0004] Currently, most lenses and other materials to be bonded are placed directly on the bonding stage without positioning. However, during the movement of the bonding stage and the extraction of air from the vacuum chamber, the lenses and other materials are prone to shifting, which can lead to low bonding accuracy and poor bonding quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vacuum bonding equipment for lens production. It solves the problem that most lenses and other materials to be bonded are placed directly on the bonding table without positioning. During the movement of the bonding table and the extraction of air from the vacuum hood, the lenses and other materials are prone to shifting, which can lead to low bonding accuracy and poor bonding quality.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a vacuum bonding equipment for lens production includes a bonding unit, wherein a positioning unit is provided on the bonding unit, and the positioning unit is used for positioning the lens and the bonding material;

[0007] The positioning unit includes:

[0008] Pull rod;

[0009] A telescopic spring, wherein the telescopic spring is disposed on the outside of the pull rod;

[0010] The positioning plate is fixedly connected to the bottom of the pull rod and to the bottom end of the telescopic spring. The positioning plate is used to fix the lens and the bonding material by the compression of the telescopic spring, so as to avoid the lens and the bonding material from misaligning.

[0011] Preferably, the bonding unit includes:

[0012] Organism;

[0013] A movable seat, which is movably disposed in the body, is used to transfer the lens and bonding material into the body for bonding.

[0014] A bonding table, which is mounted on a movable base, is used to place the lens and bonding material;

[0015] A vacuum cover is movably positioned above the bonding platform, and a pressure plate is installed inside the vacuum cover. The vacuum cover and the movable seat are tightly pressed together to form a vacuum cavity to ensure the bonding quality of the lens and the bonding material.

[0016] A hydraulic assembly, positioned above the vacuum chamber, is used to drive the vacuum chamber and pressure plate.

[0017] Preferably, the machine body is equipped with a control switch, an adjustment knob, and a display screen.

[0018] Preferably, the bottom of the movable seat is provided with a slider and a drive assembly. The slider is slidably connected to the body, and the drive assembly is connected to the movable seat and is used to drive the movable seat to reciprocate.

[0019] Preferably, the movable seat is provided with a sealing gasket, which is annular in shape and is used to ensure that the movable seat and the vacuum hood are tightly pressed together to ensure a sealed vacuum environment.

[0020] Preferably, the positioning unit further includes a support frame, which is disposed on the mating platform.

[0021] Preferably, the top end of the telescopic spring is fixedly connected to the support frame.

[0022] This utility model discloses a vacuum bonding device for lens production, which has the following beneficial effects:

[0023] This vacuum bonding equipment for lens production incorporates a positioning unit. By pulling the lever upwards, the positioning plate moves upwards, compressing the telescopic spring and placing the sides of the lens and other materials to be bonded below the positioning plate. Releasing the lever causes the telescopic spring to compress the positioning plate downwards, firmly pressing the sides of the lens and other materials onto the bonding table. This prevents the lens and other materials from shifting during the movement of the bonding table and the extraction of air from the vacuum chamber, thus improving the bonding accuracy and significantly enhancing the bonding quality.
