Technical Field

[0001] This utility model relates to the technical field of lens polishing, and in particular to a fiber optic lens polishing device. Background Technology

[0002] Fiber optic lens polishing equipment is a precision device used to process the end face of an optical fiber into a specific lens shape (such as a cone, wedge, bevel, sphere, etc.). Its core lies in achieving shape control and surface quality optimization of the fiber end face through high-precision grinding and polishing technology, thereby improving the coupling efficiency between the optical fiber and light sources such as lasers.

[0003] Currently, among existing grinding equipment, such as the patent with publication number CN210414060U, this utility model discloses a grinding device for C-lenses, including a support base, support legs provided on the left and right sides of the bottom of the support base, an installation groove opened on the top of the support base, a liquid collection groove opened at the bottom of the installation groove, a liquid outlet at the bottom of the liquid collection groove, a sealing cap at the bottom of the liquid outlet, a U-shaped support plate at the bottom of the inner cavity of the installation groove, and a clamping body at the bottom of the inner cavity of the U-shaped support plate.

[0004] In the use of existing devices, it has been found that the existing devices have poor flexibility in adjusting the grinding position of the lens, and increase the complexity of the subsequent coolant drying process, thus reducing the ease of use. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a fiber optic lens polishing device that improves the flexibility of polishing adjustment, reduces polishing dead angles, absorbs polishing dust during the polishing process through a dust removal device, reduces working environment pollution, and improves ease of use.

[0006] This utility model discloses a fiber optic lens polishing device, comprising a base and an air suction platform, the air suction platform being rotatably mounted on the base; it also includes an air suction device, an adjustment device, a dust removal device, air intakes, a cover, and polishing balls. Multiple air intakes are located at the top of the air suction platform, and the bottom of the air suction platform is connected to the air suction device. The air suction device is used to suction air from inside the air suction platform and to drive the rotation of the air suction platform. The polishing balls are rotatably mounted inside the cover, which is mounted on the adjustment device. The adjustment device is used to move and adjust the cover and to provide power for the rotation of the polishing balls. The dust removal device is included. On the base, a dust removal device is used to absorb grinding dust. The lens to be ground is placed on top of the suction table, and air is drawn into the suction table by the suction device. Multiple suction ports adsorb and fix the lens on the suction table. Then, the grinding ball is rotated by the adjustment device, which moves the cover. At the same time, the suction device drives the suction table to rotate horizontally. Thus, the rotation of the suction table and the rotation of the grinding ball work together to grind different positions of the lens, improving the flexibility of grinding adjustment and reducing grinding dead angles. During the grinding process, the dust removal device absorbs the grinding dust, reducing the pollution of the working environment and improving the convenience of use.

[0007] Preferably, the adjustment device includes a drive device, a bracket, a first motor, a guide frame, a slider, and a first electric cylinder.

When the suction table drives the lens to rotate horizontally, the first motor drives the grinding ball to rotate, and at the same time, the first electric cylinder drives the bracket to move downward, so that the grinding ball contacts the lens surface. By cooperating with the drive device to drive the slider to move horizontally, the grinding ball grinds different positions on the lens surface, improving the flexibility of grinding position adjustment.

[0008] Preferably, the dust removal device includes a dust suction hood, a collection box, a fan, and a hose. The dust suction hood is installed on the top of the base and is connected to the collection box. The fan is connected to the top of the collection box and is equipped with a filter screen at the fan input end. The hose is connected between the collection box and the hood. By drawing air into the collection box through the fan, the collection box draws air into the dust suction hood and the inside of the hood, thereby absorbing and storing the dust generated during the grinding process inside the collection box, improving the dust removal and cleaning effect.

[0009] Preferably, it also includes push blocks and second electric cylinders. Both sets of push blocks are slidably mounted on the base, and the two sets of second electric cylinders are mounted on the outer wall of the base. The moving ends of the two sets of second electric cylinders are connected to the two sets of push blocks. When the lens is placed on the suction platform, the two sets of second electric cylinders drive the two sets of push blocks to move in opposite directions, so that the two sets of push blocks center and position the lens.

[0010] Preferably, the air suction device includes a housing, a vacuum pump, and a second motor. The housing is mounted on a base, and the bottom of the air suction platform is rotatably connected to and disposed within the housing. The vacuum pump is connected to and disposed on the housing. The second motor is mounted on the outer wall of the housing, and the output end of the second motor is connected to the bottom end of the air suction platform. The second motor drives the air suction platform to rotate, causing the air suction platform to drive the lens to rotate horizontally. The vacuum pump draws air from the housing, causing the housing to draw air from the air suction platform, thereby fixing the lens on the air suction platform.

[0011] Preferably, the driving device includes a lead screw and a third motor. The lead screw is rotatably mounted on the guide frame, and the slider is screwed onto the lead screw. The third motor is mounted on the outer wall of the guide frame and connected to the lead screw. The third motor drives the lead screw to rotate, thereby driving the slider to move horizontally.

[0012] Preferably, the side of the push block is provided with an arc-shaped groove that matches the lens; this improves the accuracy of the push block in centering the lens.

[0013] Preferably, the multiple sets of air inlets are equipped with interception nets to reduce the entry of external dirt into the air intake platform and improve the cleaning and protection effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The lens to be ground is placed on the top of the suction table, and air is drawn into the suction table by the suction device, so that multiple sets of suction ports adsorb and fix the lens on the suction table. Then, the grinding ball is rotated by the adjustment device and the cover is moved to a different position. At the same time, the suction device drives the suction table to rotate horizontally, so that the rotation of the suction table and the rotation of the grinding ball are coordinated to grind different positions of the lens, improving the flexibility of grinding adjustment, reducing grinding dead angles, and the dust removal device absorbs the grinding dust during the grinding process, reducing the pollution of the working environment and improving the convenience of use.
