Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing assistance, in particular to an optical lens milling automatic feeding mechanism. Background Art

[0002] Optical glass is made of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles; then cooled slowly over a long period of time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to become optical lens blanks. At present, milling technology is one of the indispensable processes when optical lenses are processed. However, the existing optical lens milling device generally performs manual loading and unloading operations on the lenses, and does not have good safety performance. Therefore, it is urgent to design an automatic loading and unloading device for optical lenses to solve the above problems.

[0003] The existing public technology has the publication number: CN212351438U, which discloses an automatic feeding device for optical lens edge grinding, belonging to the technical field of optical lens processing auxiliary equipment, including a base plate, a motor A is installed on the upper surface of the base plate, and one end of the rotating shaft A is slidably connected to the upper surface of the motor A, and the other end of the rotating shaft A is fixedly connected to the outer wall of the bottom surface of the motor B. The utility model drives the rotating shaft A to rotate through the operation of the motor A, thereby driving the motor B to rotate, and then cooperates with the telescopic rod to extend and retract, thereby driving the vertical plate to move horizontally, so that the device can be used for feeding optical lenses with various angles and various lengths, and then drives the rotating shaft B to rotate through the operation of the motor C, thereby driving the horizontal plate A to rotate, and at the same time cooperates with the gear to drive the rotating shaft to rotate, and then the horizontal plate B can be rotated, so that the optical lens in the card slot can be stably placed on the upper surface of the workbench, which is suitable for being widely promoted and used.

[0004] Although the above patent can realize automatic loading of optical lenses, there are still some shortcomings in its use. First of all, the patent adopts the method of placing the optical lens inside the card slot, and then controlling the position adjustment of the card slot by motor A2 and motor B4, and finally controlling the operation of motor C11 to rotate the horizontal plate A and the horizontal plate B to place the optical lens on the workbench. When the horizontal plate is opened, the optical lens on the horizontal plate may be unstable or have surface scratches, resulting in the position of the optical lens on the workbench being offset, affecting subsequent processing. Secondly, the card slot of the patent can only realize displacement adjustment in the horizontal and circumferential directions, and lacks position adjustment in the vertical direction, which limits the applicability of the device to a certain extent. No effective solution has been proposed for the problems in the relevant technology. Utility Model Content
