Description

Technical Field

[0001] This utility model relates to the field of glass cutting devices, specifically to a cutting device for glass parts with low surface flatness. Background Technology

[0002] Glass is one of the most commonly used materials in everyday consumer goods, and its production often requires cutting. The cutting method typically employs crack control, which involves first heating the glass surface with a laser cutting head. The high energy causes a rapid increase in temperature, generating significant compressive stress and creating a cut on the surface. The second step involves rapidly cooling the area to be cut. This rapid cooling creates a large temperature gradient and tensile stress on the glass surface, causing it to crack along the pre-marked lines, thus achieving the cut.

[0003] Existing cutting devices include laser cutting components and clamping mechanisms, but such as Figure 1 The glass component shown has a low surface flatness. Depending on the cutting position, the required cut depth of the laser cutting assembly on the outer periphery of the glass component varies. Furthermore, the distance between the existing laser cutting assembly and the outer periphery of the glass component is usually fixed, meaning the cut depth cannot be adjusted accordingly. Figure 1 The cut position of the glass component shown has changed and is not applicable to, for example, Figure 1 The glass piece shown was poorly cut. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a cutting device for glass parts with low surface flatness, comprising:

[0005] A cutting assembly, comprising a carrier and a laser cutting head connected to the carrier, and a moving cylinder, the output end of which is connected to the carrier, and the moving cylinder being used to drive the laser cutting head to move.

[0006] The transfer assembly includes a lifting module and a frame one connected to the output end of the lifting module. The frame one is equipped with a rotary cylinder, and the output end of the rotary cylinder is equipped with a frame two. The frame two is equipped with a pneumatic gripper. The pneumatic gripper is used to grip the glass piece. The lifting module is used to drive the pneumatic gripper to lift and lower, and the rotary cylinder is used to drive the pneumatic gripper to rotate while gripping the glass piece.

[0007] A rotating platform is connected to a drive motor. The rotating platform is provided with a limiting component for limiting the glass piece. The drive motor is used to drive the rotating platform to rotate.

[0008] Furthermore, it also includes a frame, on which a connecting rod is provided, and a compression spring is sleeved on the connecting rod. The first carrier is provided with a connecting hole corresponding to the connecting rod, and the connecting rod passes through the connecting hole. The two ends of the compression spring press against the frame and the first carrier, respectively.

[0009] Furthermore, the first carrier is equipped with an adjusting cylinder, the output end of the adjusting cylinder is equipped with a second carrier, the second carrier is equipped with a roller, and the adjusting cylinder is used to drive the roller to move to contact the glass piece.

[0010] Furthermore, the limiting component includes a limiting cylinder, and the output end of the limiting cylinder is provided with a limiting block. The limiting cylinder is used to drive the limiting block to move and contact the outer periphery of the glass piece.

[0011] Furthermore, the limiting block is provided with a contour groove corresponding to the outer periphery of the glass component.

[0012] Furthermore, multiple limiting blocks are provided, and the multiple limiting blocks are evenly distributed around the outer periphery of the glass piece.

[0013] The beneficial effects of this utility model are as follows: by setting up a moving cylinder and cooperating with the lifting module, the glass part is lifted and lowered by the pneumatic gripper driven by the lifting module as the cutting position of the glass part changes. The glass part is then limited by the limiting component on the rotating table, and the distance between the laser cutting head and the glass part is adjusted by the moving cylinder driven by the laser cutting head. This makes the distance between the laser cutting head and the glass part adapt to the depth of the cut that needs to be made, thereby improving the cutting effect. Attached Figure Description

Detailed Implementation

[0021] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figure 2 This utility model provides a cutting device 100 for glass parts with low surface flatness, including a cutting assembly, a transfer assembly, and a rotating table 30. The cutting assembly includes a carrier frame 11 and a laser cutting head 12 connected to the carrier frame 11. Specifically, in this embodiment, the laser cutting head 12 is also connected to a laser generating module (not shown in the figure) for generating laser light, and the laser cutting head 12 is a Bezier laser cutting head 12 in the prior art.

[0023] Please refer to Figure 2 The transfer assembly includes a lifting module 21 and a first frame 22 connected to the output end of the lifting module 21. The first frame 22 is equipped with a rotary cylinder 23, and the output end of the rotary cylinder 23 is equipped with a second frame 24. The second frame 24 is equipped with a pneumatic gripper 25, which is used to grip the glass piece 200. The lifting module 21 drives the pneumatic gripper 25 to lift and lower, and the rotary cylinder 23 drives the pneumatic gripper 25 to rotate while gripping the glass piece 200. Specifically, in this embodiment, the lifting module 21 is a lead screw transmission mechanism as used in the prior art. The pneumatic gripper 25 grips the glass piece 200, and the lifting module 21, in conjunction with the rotary cylinder 23, drives the pneumatic gripper 25 to move while gripping the glass piece 200, so that the glass piece 200 is placed on or removed from the rotating table 30, thereby completing the transfer of the glass piece 200.

[0024] Please refer to Figure 1Because the outer periphery flatness of the glass component 200 involved in this application is relatively low, the outer periphery diameter of the glass component 200 varies depending on the location to be cut, and the depth of the cut required by the laser cutting head 12 is also different. Therefore, it is necessary to adjust the distance between the laser cutting head 12 and the glass component 200. Please refer to... Figure 2 The cutting assembly also includes a movable cylinder 40, the output end of which is connected to the carrier 11. The movable cylinder 40 is used to drive the laser cutting head 12 to move. Through the movable cylinder 40, in conjunction with the lifting module 21, as the cutting position of the glass part 200 changes, the lifting module 21 drives the pneumatic gripper 25 to lift and lower the glass part 200, which is then limited by the limiting component on the rotating table 30. The movable cylinder 40 drives the laser cutting head 12 to adjust the distance between the laser cutting head 12 and the glass part 200, ensuring that the distance between them is adapted to the depth of the cut required, thereby improving the cutting effect.

[0025] Please refer to Figure 4 and Figure 5 The cutting device 100 for glass parts with low surface flatness also includes a frame 50, a connecting rod 51 on the frame 50, a compression spring 52 on the connecting rod 51, and a connecting hole 111 on the carrier 11 corresponding to the connecting rod 51. The connecting rod 51 passes through the connecting hole 111, and the two ends of the compression spring 52 press against the frame 50 and the carrier 11 respectively.

[0026] To facilitate adjustment of the distance between the glass component 200 and the laser cutting head 12, the laser cutting head 12 needs to contact the outer periphery of the glass component 200 before cutting, and then move the laser cutting head 12 away from the glass component 200. When the laser cutting head 12 contacts the outer periphery of the glass component 200 before cutting, the compression spring 52, through the setting of the compression spring, when the moving cylinder 40 drives the carrier 11 to move the laser cutting head 12, the connecting rod 51 slides in the connecting hole 111, and the compression spring 52 is deformed by pressure, thereby exerting a reverse pushing force on the carrier 11. This reduces the possibility of damage to the glass component 200 before cutting due to excessive force exerted on the glass component 200 by the laser cutting head 12 relative to the glass component 200 during its movement.

[0027] Please refer to Figure 4 and Figure 5The first carrier 11 is equipped with an adjusting cylinder 112, and the output end of the adjusting cylinder 112 is equipped with a second carrier 1121. The second carrier 1121 is equipped with a roller 1122. The adjusting cylinder 112 is used to drive the roller 1122 to move to contact the glass component 200. By setting the adjusting cylinder 112, when the glass component 200 rotates, the adjusting cylinder 112 drives the roller 1122 to move to roll contact with the outer periphery of the glass component 200. When the glass component 200 rotates, the roller 1122 further increases the contact area with the glass component 200, thereby increasing the limiting effect on the glass component 200 and further improving the limiting effect on the glass component 200.

[0028] Please refer to Figure 2 and Figure 3 The rotating table 30 is connected to a drive motor 31, which drives the rotating table 30 to rotate. The rotating table 30 is equipped with a limiting assembly for limiting the glass piece 200. The limiting assembly includes a limiting cylinder 32, and the output end of the limiting cylinder 32 is provided with a limiting block 321. The limiting cylinder 32 drives the limiting block 321 to move and contact the outer periphery of the glass piece 200. Specifically, to improve the limiting effect on the glass piece 200, the limiting block 321 is provided with a contour groove 3211 corresponding to the outer periphery of the glass piece 200.

[0029] As one specific implementation method, please refer to Figure 2 and Figure 3 Multiple limiting blocks 321 are provided, and the multiple limiting blocks 321 are evenly distributed around the outer periphery of the glass component 200.

[0030] By setting the limiting block 321 and the limiting cylinder 32, when the glass part 200 is laser cut, the limiting cylinder 32 drives the limiting block 321 to abut against the outer periphery of the glass part 200, so that the glass part 200 is not easy to shake when it is cutting and rotating, thereby improving the cutting effect.
