Description

Technical Field

[0001] The present invention relates to the technical field of glass edge breaking, in particular to an edge breaking device for processing carrier glass. Background Art

[0002] Glass edge bending is an important process in the glass processing. Its purpose is to cut and trim the edges of the glass according to the design requirements to facilitate subsequent processing and following. The principle is that when the glass is subjected to local stress concentration, the internal cracks will expand rapidly, causing it to break along a specific direction. The glass edge bending process is widely used in architectural glass, automotive glass and other fields.

A circular glass scoring and bending device, including a device body, one end of the device body is equipped with a bending waste placement plate, the middle of the device body is equipped with a supporting plate, the middle of the supporting plate is provided with a disengagement hole, two push rollers are installed on both sides of the supporting plate, and a circular glass bending mechanism is installed above the pushing roller. The present invention can score the glass raw materials during the circular glass production process, and can bend the glass sheets around the circular glass after scoring, without the need for manual operation, without causing harm to workers, with a simple structure and easy operation."

[0004] The above patent still has shortcomings in actual use. During the pre-cutting process before bending the glass, the glass surface is cut through the cut path.

[0022] During operation, the glass to be bent is placed on the top of the transport module 2 through the loading module 101 on the top of the base 1, and then the transport module 2 transports the glass to the bottom of the fine-adjustable support frame 201. Through the control of the transport module 2, the area of the glass to be bent is driven to the top of the scribing platform body 205 and aligned with the slider 204; then the height of the fine-adjustable support frame 201 is adjusted so that the bevel gear set 304 at the bottom of the slider 204 is in contact with the glass. At this time, the servo motor 202 is driven to drive the screw rod 203 to start rotating. At the same time, the top of the slider 204 is limited by the slide column 3, so that the slider 204 starts to slide outside the screw rod 203. When the slider 204 starts to slide, the cutting head 306 is blocked by the limiting push rod 308. The slider 204 remains stationary, so that the cutting head 306 cuts and forms scratches on the surface of the glass. The scribing position is located on the top of the scribing platform body 205. The scribing platform body 205 provides excellent support for the bottom of the glass. At the same time, when the slider 204 moves, the fixed rack 301 inside the slide column 3 continuously meshes with the rotating gear A302 inside the slider 204, so that the rotating gear A302 starts to rotate. At this time, the rotating gear A302 drives the gear rod 303 to rotate, and the gear rod 303 drives the bevel gear set 304 and then drives the pawl sleeve 4, so that it is continuously meshed with the ratchet 401. However, when the cutting head 306 is limited by the limiting push rod 308, the pawl sleeve 4 cannot be moved due to the characteristics of the ratchet 401 itself. The ratchet 401 and the grinding wheel 307 are driven to rotate inside the slider 204. When the cutting head 306 completes the marking, the servo motor 202 is driven in the reverse direction to reset the slider 204. At this time, the driving direction of the pawl sleeve 4 starts to change due to the bevel gear set 304. At the same time, the limiting push rod 308 does not limit the cutting head 306, so that the grinding wheel 307 can start to rotate under the drive of the pawl sleeve 4 and the ratchet 401. At the same time, when the slider 204 moves in the opposite direction, the fine-tuning support frame 201 will sink. At the same time, due to the different number of meshing teeth of the rotating gear A302 and the gear rod 303, the gear rod 303 is accelerated, so that the grinding wheel 307 rotates at a high speed to groove the position of the glass marking. When the grooving is completed, the transport module 2 Continue working and transport the glass to the position close to the telescopic rod A5. At this time, the telescopic rod A5 starts to drive the edge breaking block 501 and the telescopic rod B502 to descend, making them close to the glass, so that the friction pad 6 at the bottom of the cam pressing head 505 is in close contact with the glass. At this time, the cam pressing head 505 is located on the outside of the cutting groove. At this time, the telescopic rod B502 continues to descend, driving the vacuum suction cup 503 to approach the middle of the glass, so that the vacuum suction cup 503 adsorbs the glass. At the same time, the pressure block 509 will squeeze the sliding rack 508. When the sliding rack 508 descends, it drives the rotating gear B507 to rotate. At the same time, the return spring 601 is compressed and contracted. The rotating gear B507 causes the cam pressing head 505 to rotate around the support block 504 through the synchronous belt 506.Due to the shape limitation of the cam pressing head 505, the cam pressing head 505 slowly applies pressure to the glass in close contact with it while rotating until it breaks. In the process of the cam pressing head 505 applying pressure, the friction pad 6 applies an outward pulling force to the glass. The outward pulling force can increase the stress intensity at the crack tip, making the crack easier to expand. At the same time, it has a certain guiding effect, reducing the possibility of crack deviation. When the edge breaking is completed, the vacuum suction cup 503 grabs the finished product, and then rotates the telescopic rod A5 to place the glass Finished products are collected inside the storage box 102. At this point, the telescopic rod B502 is reset, and the reset spring 601 rebounds, driving the cam pressing head 505 and the sliding rack 508 to reset. The transport notching assembly and the glass edge bending assembly work together to create V-shaped grooves on the scratches instead of pre-treating them before edge bending. This makes it easier to break the glass along the grooves during subsequent edge bending. The fracture path is also more precise, and the edges are smoother. This can improve the yield rate when processing glass with high edge bending precision requirements.

[0023] For further information, see Figure 1-3 、 Figure 6 As shown, the outer bottom of the telescopic rod A5 is hinged with a hinge shaft 7; the outer side of the hinge shaft 7 is hinged with a connecting rod 701; the connecting rod 701 is rotatably connected to a support wheel 702 at one end away from the hinge shaft 7; the bottom of the support wheel 702 is fixed with a compression spring 703; one end of the compression spring 703 is interconnected with the base 1, and the outer top of the transport module 2 is rotatably connected with an adjusting screw 801; the outer side of the adjusting screw 801 is threadedly connected to a lower pressure roller 8, and the outer side of the adjusting screw 801 is fixed with a support spring 9; the support spring 9 is located at the bottom of the lower pressure roller 8, and a negative pressure port 10 is opened on the inner side of the base 1 near the connecting rod 701. The negative pressure port 10 absorbs small debris generated by the glass during the bending process, thereby reducing the impact of glass debris flying everywhere on the working environment.

[0024] During operation, when the glass moves to the position to be bent, the glass will squeeze the support wheel 702. At this time, the compression spring 703 is compressed and contracted, and the support wheel 702 drives the connecting rod 701 to rotate around the hinge shaft 7. The position of the support wheel 702 is facing the bottom of the glass groove. The compression spring 703 will apply a certain force upward. According to the thickness of the glass to be processed as needed, the adjusting screw 801 is turned to adjust the height of the lower pressure roller 8 at the top of the transport module 2. The support spring 9 supports the lower pressure roller 8, making the lower pressure roller 8 more stable at the top of the transport module 2, further improving the stability of the glass during transportation. Through the use of the support wheel 702 and the compression spring 703, pressure is applied to the bottom of the groove to form a reverse support at its bottom, optimize the concentration of force, reduce the expansion of edge microcracks, and further increase the yield rate of the processed finished product.

[0025] To sum up, the problem that the glass surface is cut through the cutting track during pre-cutting before bending the glass is effectively solved. Since the cutting marks are shallow, only tiny cracks are formed on the glass surface. When bending the glass, the stress concentration effect is weak, and a greater downward force needs to be applied. The possibility of the fracture direction shifting will also increase. When bending the glass with higher precision requirements, the yield rate will be reduced.
