Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and specifically to a rotary positioning device for laser cutting of optical components. Background Technology

[0002] With the widespread application of optical technology in numerous fields such as communications, medical, and semiconductor manufacturing, the demand for optical components has increased dramatically. Traditional manual or semi-automatic optical component cutting devices suffer from low cutting precision and difficulty in achieving consistent positioning, resulting in low yield rates for optical components. Furthermore, optical component materials such as acrylic and COC are characterized by high hardness and brittleness, making them prone to defects such as cracks and edge chipping during the cutting process.

[0003] Laser cutting can reduce damage during the shearing process caused by the hardness and brittleness of materials. However, in traditional equipment, the laser cutting and handling processes are often independent, making precise coordinated control impossible. Modern manufacturing demands increasingly higher production efficiency and quality stability. Manual operation is not only inefficient but also highly susceptible to human factors, making it difficult to guarantee consistent product quality.

[0004] Therefore, a rotary positioning device for laser cutting of optical components is needed to improve production efficiency and product quality, and to meet the needs of large-scale production. Utility Model Content

[0005] The purpose of this invention is to provide a rotary positioning device for laser cutting of optical components.

[0006] This utility model provides the following technical solution:

[0007] This utility model proposes a rotary positioning device for laser cutting of optical components, including a rotary cylinder and a driven shaft. A positioning plate is provided between the rotary cylinder and the driven shaft. The positioning plate has a material head clearance opening and a pair of positioning grooves for restricting optical components. The positioning grooves are located on both sides of the material head clearance opening. The positioning plate is provided with a clamping cylinder for clamping the optical components on the positioning grooves.

[0008] Furthermore, the clamping arm of the clamping cylinder is Z-shaped, and a Teflon pressure plate is fixed to the lower end of the clamping arm.

[0009] Furthermore, the positioning plate is a Teflon positioning plate.

[0010] Furthermore, it also includes a first fixing plate and a second fixing plate for fixing to an external platform, with the rotary cylinder fixed on the first fixing plate and the driven shaft fixed on the second fixing plate.

[0011] Furthermore, the driven shaft is a 626 bearing.

[0012] Furthermore, there are two clamping cylinders, each corresponding to clamp the optical element in the positioning groove.

[0013] Compared with existing technologies, this invention limits the optical components by using a positioning groove and a clamping cylinder; and uses a rotary cylinder and a driven shaft to flip the product so that an external laser cutting device can cut the product, ensuring the high precision requirements of optical component manufacturing and reducing the insufficient precision of manual cutting. This provides a strong guarantee for manufacturing highly stable and high-quality components. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] See Figure 1 , Figure 2 and Figure 3A rotary positioning device for laser cutting optical components includes a rotary cylinder 1 and a driven shaft 2. A positioning plate 3 is disposed between the rotary cylinder 1 and the driven shaft 2. The positioning plate 3 has a material head clearance opening 31 and a pair of positioning grooves 32 for restricting the optical components. The positioning grooves 32 are located on both sides of the material head clearance opening 31. A clamping cylinder 4 is disposed on the positioning plate 3 for clamping the optical components on the positioning grooves. In practical applications, the product 00 before cutting is placed on the positioning plate 3, wherein the optical components of the product 00 are restricted to the positioning grooves 32. Subsequently, the optical components 00 are clamped by the clamping cylinder 4 to prevent the optical components from shifting during flipping and cutting. Then, the rotary cylinder 1 is activated, and the rotary cylinder 1 drives the positioning plate 3 to flip. After flipping until the positioning grooves 32 face down, laser cutting is performed by an external laser cutting device, and the cut material head 01 falls off naturally.

[0021] In the above embodiments, see Figure 1 One end of the positioning plate 3 is connected to the output shaft of the rotary cylinder 1, and the other end of the positioning plate 3 is connected to the driven shaft; the output shaft of the rotary cylinder drives the positioning plate 3 to rotate.

[0022] See Figure 1 or Figure 2 In one embodiment of this utility model, the clamping arm 41 of the clamping cylinder 4 is Z-shaped, and a Teflon pressure plate 5 is fixed at the lower end of the clamping arm 41; the clamping arm 41 has a large contact surface with the optical element in the positioning groove, so that the clamping arm 41 can firmly clamp the optical element in the positioning groove, ensuring that the product does not shift during rotation and cutting; at the same time, the Teflon material has excellent anti-stick and stain-resistant properties, which can effectively prevent dirt from getting on the surface of the optical element.

[0023] In one embodiment of this utility model, the positioning plate 3 is a Teflon positioning plate; Teflon material has excellent anti-stick and stain-resistant properties, which can effectively prevent dirt from getting on the surface of optical components.

[0024] See Figure 1 In one embodiment of this utility model, it further includes a first fixing plate 6 and a second fixing plate 7 for fixing on an external platform. The rotary cylinder 1 is fixed on the first fixing plate 6, and the driven shaft 2 is fixed on the second fixing plate 7.

[0025] In one embodiment of this utility model, the driven shaft 2 is a 626 bearing; one end of the positioning plate 3 is fixed to the output shaft of the rotary cylinder 1, and the other end of the positioning plate 3 is fixed inside the bearing; so that the positioning plate can be rotated along the axis (rotary cylinder-driven shaft).

[0026] See Figure 1In one embodiment of this utility model, there are 2 clamping cylinders, which are respectively used to clamp the optical elements in the positioning groove 32.

[0027] In one embodiment of this utility model, the rotary cylinder 1 is an Airtac rotary cylinder HRS15X180, which features precise rotation angle and rapid response.

[0028] In one embodiment of this utility model, the clamping cylinder 4 is an Airtac clamping cylinder QCKR12X10SM.

[0029] In practical applications, the first and second fixing plates are fixed to the external platform respectively. The product before cutting is placed on the positioning plate, where the optical element of the product is confined to the positioning groove. Then, the optical element is clamped by a clamping cylinder to prevent displacement of the optical element during flipping and cutting. Next, the rotary cylinder is started, and the output shaft of the rotary cylinder drives the positioning plate to flip. After flipping to the position groove facing down, laser cutting is performed by an external laser cutting device, and the cut material head falls off naturally. Finally, the rotary cylinder is used to flip the positioning plate back to the initial state, the clamping cylinder releases the optical element, and it is taken out, thus obtaining the cut optical element.
