[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Reference Figure 1-Figure 10 The beveling equipment comprises: a stable workbench 1, which serves as a supporting platform for the whole equipment. A sliding device is designed and installed on the top of the workbench 1, so that a moving table 4 can move smoothly along the top of the workbench 1. Two sets of well-designed clamps are arranged on the moving table 4, which are used to alternately fix special-shaped glasses of different shapes to ensure the stability and accuracy of the glass during the processing.

[0047] In order to control the movement of the movable table 4, two second electric push rods 3 are installed on the top of the workbench 1, and their output ends are firmly connected to the movable table 4. By controlling the extension and retraction of the second electric push rods 3, the position of the movable table 4 on the workbench 1 can be accurately adjusted to meet different processing requirements.

[0048] Next, a mechanism for chamfering the top of the glass is set. Two first electric push rods 2 are fixedly installed at the bottom of the workbench 1, and their output ends penetrate the top of the workbench 1 and are connected to the connecting column 6. Two lifting blocks 7 are fixed on the top of the connecting column 6, and two guide bars 8 are connected between the two lifting blocks 7 through a set of adjustment mechanisms. The design of the guide bars 8 allows the distance between them to be adjusted according to the size of the glass, so as to adapt to the processing requirements of glass of different sizes.

[0049] A first mounting seat 21 is slidably mounted in the guide bar 8, and a first laser head 22 and a second laser head 23 are fixed to each mounting seat. The two laser heads are used to perform precise chamfering on the top of the glass. In order to drive the first mounting seat 21 to move along the guide bar 8, a motor 19 is installed on one side of a lifting block 7, and its output end is connected to the two first mounting seats 21 through a transmission device to achieve synchronous movement.

[0050] In order to ensure the safety of the operators, the protective covers 5 are fixedly installed on the two lifting blocks 7 to effectively isolate the laser processing area and reduce the potential harm of laser radiation to personnel.

[0051] In addition, in order to meet the demand for chamfering the end face of the glass, two second mounting seats 26 are adjustable between the two lifting blocks 7. A third laser head 27 and a fourth laser head 28 are respectively mounted on each second mounting seat 26 for chamfering the end face of the glass. These laser heads can move adaptively according to the shape of the end face of the glass to ensure processing accuracy. Similarly, the second mounting seat 26 is also connected to the output end of the motor 19 through a transmission device to achieve swing cutting. The first laser head 22, the second laser head 23, the third laser head 27 and the fourth laser head 28 all use the laser in the patent document CN205043350U.

[0052] The laser head includes an optical path system 43, an angle swing mechanism 44, and a focusing mechanism 45. The angle swing mechanism 44 is installed between the optical path system 43 and the focusing mechanism 45. A reflector is installed in the angle swing mechanism 45. The angle between the reflector and the incident light can be adjusted to change the emission angle of the reflected light. In this application, the emission angle can be adjusted to 45°.

[0053] In order to achieve accurate movement and swing of the first mounting seat 21 and the second mounting seat 26, the first screw rod 9 is rotatably installed between the two lifting blocks 7, and the outer wall of the screw rod 9 is threadedly sleeved with a nut block 11. The bottom of the nut block 11 is fixedly connected to the connecting platform 12, and the first sliding rods 20 are slidably installed at both ends of the connecting platform 12, and these first sliding rods 20 are fixedly connected to the first mounting seat 21. The output end of the motor 19 is fixedly connected to one end of the first screw rod 9. When the motor 19 is running, the first mounting seat 21 is driven to move along the guide bar 8 through the threaded cooperation between the first screw rod 9 and the nut block 11.

[0054] At the same time, in order to drive the second mounting seat 26 to swing, a rotating rod 10 is also installed and rotated between the two lifting blocks 7. An electromagnetic clutch 15 is installed and installed on one side of one of the lifting blocks 7, and its input end is meshed with the first gear 16 of the first screw rod 9, and the output end is fixedly connected to one end of the rotating rod 10. The outer wall of the rotating rod 10 is provided with a sliding plate 24, and these sliding plates 24 are fixedly connected to the second mounting seat 26. When the electromagnetic clutch 15 is working, it can switch the power transmission path so that the rotating rod 10 drives the sliding plate 24 and the second mounting seat 26 to swing, thereby realizing the swing cutting of the laser head. In order to fix the position of the sliding plate 24, a first bolt 34 is installed and threaded on one side of it. By rotating the first bolt 34 so that one end of it contacts the rotating rod 10, the sliding plate 24 is fixed.

[0055] And multiple groups of pressing mechanisms are arranged between the two lifting blocks 7 and move up and down with them. These pressing mechanisms are used to firmly fix the glass on the fixture during the processing to ensure the stability and accuracy of the processing.

[0056] In order to make the second mounting seat 26 move along with the shape of the glass end face when swinging, an extension rod 29 is fixedly installed on one side of each second mounting seat 26, and the horizontal part of the extension rod 29 extends outward and is perpendicular to the second mounting seat 26. A guide roller 30 is rotatably sleeved on the outer wall of the extension rod 29. When the laser head descends to process the glass, the inner wall of the glass will contact the guide roller 30 and rotate. Since the guide roller 30 is rotatably connected to the extension rod 29, the rotation of the guide roller 30 will drive the second mounting seat 26 to slide along the slide groove in the sliding plate 24, thereby moving the second mounting seat 26 away from the corresponding guide strip 8. In this way, the second mounting seat 26 can automatically avoid the guide strip 8 and drive the laser head to move along the shape of the glass end face.

[0057] The fixture includes two groups of fixed seats 40 fixedly installed on the top of the moving platform 4, and the number of each group of fixed seats 40 is determined according to actual needs. A rotating block 41 is rotatably installed on the top of each fixed seat 40, and the rotating block 41 is connected to the fixed seat 40 through a damping device to ensure that the rotating block 41 will not rotate by itself without external force. A suction cup 42 is fixedly installed on the top of the rotating block 41 for adsorbing and fixing the glass. In order to support the bottom of the glass, two limit seats 39 are also set on the top of the moving platform 4, and each limit seat 39 is located between each group of fixed seats 40.

[0058] The pressing mechanism includes a rotating ring 13 rotatably mounted on the outer wall of the rotating rod 10, and the rotating ring 13 will not rotate with the rotation of the rotating rod 10. A plurality of sleeve rods 14 are fixedly mounted on the outer wall of the bottom of the rotating ring 13, and the bottom of the sleeve rods 14 is an open structure. A resisting rod 35 is slidably mounted at the bottom of each sleeve rod 14, and the top of the resisting rod 35 is connected to the top wall of the sleeve rod 14 by a second spring 37. The second spring 37 is in a compressed state to provide a downward elastic force, so that the resisting rod 35 always has a downward tendency. A rubber pad 36 is fixedly mounted at the bottom of the resisting rod 35 to increase the friction between the glass, and under the gravity of the sleeve rod 14, the resisting rod 35, the second spring 37 and the rubber pad 36, the plurality of sleeve rods 14 are always facing downward.

[0059] The present application can be used in the field of laser chamfering, and can also be used in other fields applicable to the present application.

[0060] Example 2: Reference Figure 1-Figure 11 , improved on the basis of Example 1: Picosecond laser glass chamfering equipment, which is applied to the field of laser chamfering. In order to allow the sliding plate 24 to be adjusted together with the guide bar 8, two parallel sliding grooves are designed inside the sliding plate 24, and a second sliding rod 25 is slidably installed in each sliding groove. In order to ensure the stability of the second sliding rod 25 during the sliding process, limiting protrusions are provided on the inner walls on both sides of each sliding groove. At the same time, a first spring 33 is installed at the bottom of each of the two sliding grooves, one end of the first spring 33 is fixedly connected to the bottom of the sliding groove, and the other end is fixedly connected to the bottom of the second sliding rod 25. In this way, when the second sliding rod 25 is subjected to external force, it can slide in the sliding groove and compress or stretch the first spring 33.

[0061] The tops of the two second sliding rods 25 are respectively fixedly connected to the corresponding second mounting seats 26. When the second mounting seats 26 are in the initial position, due to the force of the first spring 33, the second mounting seats 26 will tightly contact one side of the corresponding guide strip 8. In this way, when processing glass of different sizes, the second mounting seats 26 can automatically adjust their positions to ensure that the laser head can always accurately align with the end face of the glass.

[0062] In order to facilitate the adjustment of the spacing between the two guide bars 8, a guide rod 31 is fixedly installed on one side of each lifting block 7, and a second screw rod 32 is rotatably installed on the other side. One of the guide bars 8 is slidably sleeved on the two guide bars 31 to ensure that it can only move along the axial direction of the guide bar 31; the other guide bar 8 is threadedly sleeved on the two second screw rods 32, and the axial movement of the guide bar 8 can be achieved by rotating the second screw rods 32. In order to synchronously move the two guide bars 8, two racks 17 are fixedly installed on the side of the two guide bars 8 close to each other. At the same time, two second gears 18 are rotatably sleeved on the outer wall of the rotating rod 10 through bearings, the inner ring of the bearing is fixedly sleeved on the outer wall of the rotating rod 10, and the second gear 18 is fixedly sleeved on the outer ring of the bearing, so that the rotation between the second gear and the rotating rod 10 will not affect each other, and can rotate accordingly, and the two second gears 18 are respectively engaged with the corresponding two racks 17. When the second screw rod 32 is rotated, one guide bar 8 can be driven to move, and the two second gears 18 can be driven to rotate synchronously through the rack 17, thereby driving the two guide bars 8 to move closer to or farther from each other at the same time through the rack 17.

[0063] A second bolt 38 is threadedly installed through the outer wall of each sleeve rod 14, and the axis of the second bolt 38 is perpendicular to the axis of the sleeve rod 14. When it is necessary to fix the height of the interference rod 35, the second bolt 38 can be rotated to make one end of it interfere with the interference rod 35 and fix the interference rod 35 at a desired position. In this way, the height of the interference rod 35 can be adjusted according to the different thicknesses of glass to ensure that it can effectively fix the glass on the fixture.

[0064] A control system for a picosecond laser glass beveling device, used to control the above-mentioned picosecond laser glass beveling device, including: a controller, an input device, an output device, a communication interface, a power supply and a human-computer interaction interface;

[0065] The controller is responsible for receiving and processing signals from input devices, and issuing control instructions according to preset programs and algorithms to drive various output devices to work;

[0066] Input devices include sensors;

[0067] The output device operates according to the instruction of the controller, and the output device includes a first electric push rod 2, a second electric push rod 3, a motor 19, a first laser head 22, a second laser head 23, a third laser head 27, a fourth laser head 28 and a suction cup 42;

[0068] The communication interface is used to connect the controller, input device, output device, and human-computer interaction interface;

[0069] The power supply is used to supply power to:

[0070] Human-machine interaction interface: used for operators to interact with the control system, set processing parameters, monitor the processing process, and adjust the equipment status.

[0071] In the present application, when in use, the device is powered on, and then the glass is placed on the outer limiting seat 39. During the placement process, the suction cup 42 can be driven to flip so that the inner side contacts the outer surface of the glass until the bottom of the glass contacts the limiting seat 39, and the suction cup 42 is activated so that the suction cup 42 is adsorbed on the glass;

[0072] Then, the two first electric push rods 2 are started to extend at the same time. The extension of the first electric push rod 2 can drive the lifting block 7 to move upward through the connecting column 6, and drive the guide bar 8 and the protective cover 5 to move upward until they move to a safe height. Then, the second electric push rod 3 is started to extend. During the extension of the second electric push rod 3, the movable platform 4 can be driven to move on the workbench 1, and the glass on one side can be driven to move between the two lifting blocks 7. Then, the first electric push rod 2 is started to retract, and the lifting block 7 can be driven to move downward. During the downward movement of the lifting block 7, the connecting platform 12 can be driven to move downward through the two guide bars 8 and the first screw 9, and the positions of the two groups of first laser heads 22 and second laser heads 23 are adjusted according to the width of the glass. This adjustment method is: rotate the second screws 3 on both sides at the same time. 2. The rotation of the second screw rod 32 can drive the guide bar 8 on one side to move, and the guide bar 8 can drive the corresponding rack 17 to move when it moves. The movement of the rack 17 can drive the other rack 17 to move in the opposite direction through the meshing of the rack 17 and the second gear 18, so as to drive the two guide bars 8 to move relative to each other. During the movement of the guide bar 8, the two first mounting seats 21 can be driven to move relative to each other, so as to adjust the positions of the two groups of first laser heads 22 and second laser heads 23. During the movement of the guide bar 8, the first spring 33 can resist the second sliding rod 25 to move outward, and drive the second mounting seat 26 to move, so that one end of the second mounting seat 26 resists against one side of the guide bar 8, so that the third laser head 27 and the fourth laser head 28 can correspond to the width of the glass.

[0073] Then, the positions of the two sets of third laser heads 27 and fourth laser heads 28 are adjusted according to the length of the glass. The adjustment method is: rotate the first bolt 34 to make one end of the first bolt 34 away from the rotating rod 10, and then push the sliding plate 24 to move on the rotating rod 10. The movement of the sliding plate 24 can drive the second mounting seat 26 to move through the second sliding rod 25, thereby driving the third laser head 27 and the fourth laser head 28 to move to one side of the end face of the glass. Finally, rotate the first bolt 34 in the opposite direction to make one end of the first bolt 34 contact the outer wall of the rotating rod 10 to fix the sliding plate 24.

[0074] After the adjustment is completed, the first electric push rod 2 is started to retract and drive the lifting block 7 to move downward until the first laser head 22 and the second laser head 23 move to the cutting position. At the same time, during the downward movement, the fourth laser head 28 can contact the inner wall of the glass, and the second mounting seat 26 is driven away from the guide bar 8 by the fourth laser head 28. During the downward movement of the lifting block 7, the protective cover 5 can be driven to move downward for shielding. At the same time, the rotating rod 10 drives multiple sleeve rods 14 to move downward. Since the rotating ring 13 is rotatably arranged on the rotating rod 10, the sleeve rod 14 located in the middle is always in a downward position. When the rubber pad 36 contacts the glass, it continues to move downward to cooperate with the resistance rod 35 to compress the second spring 37 until it moves into place, and the glass panel on one side of the protective cover 5 is opened, and the second bolt 38 is manually screwed so that one end of the second bolt 38 is against the resistance rod 35 to complete the fixing of the glass.

[0075] Restart the motor 19 to drive the first screw 9 to rotate. The rotation of the first screw 9 can drive the nut block 11 to move. The movement of the nut block 11 can drive the first mounting seats 21 on both sides to move in the corresponding guide strips 8 through the connecting platform 12 and the first sliding rod 20. At the same time, the first laser head 22 and the second laser head 23 are started to cut and chamfer the inner and outer corners of the glass. When the connecting platform 12 is away from the sliding plate 24 on one side, the electromagnetic clutch 15 is started. At this time, the rotation of the first screw 9 can drive the input end of the electromagnetic clutch 15 to rotate through the two meshing first gears 16. The input end of the electromagnetic clutch 15 can drive the output end to rotate, which can drive the rotating rod 10 to rotate. The rotation of the rotating rod 10 can drive the sliding plate 24 to rotate. At the same time, the third laser head 27 and the fourth laser head 28 are started to cut and chamfer the end face of the glass. During the swinging of the sliding plate 24, the fourth laser head 28 can move according to the inner wall of the glass, drive the second mounting seat 26 to move, and drive the second sliding rod 25 to compress the first spring 33.

[0076] During the cutting process, unprocessed glass continues to be placed on another workstation and processed in sequence. After the first laser head 22, the second laser head 23, the third laser head 27 and the fourth laser head 28 are adjusted, they can be used continuously and adjusted again when the glass size is changed.
