The glass located in the middle of the processing table is difficult to reach manually, which further increases the difficulty of manual labeling. The shortcomings of the above-mentioned existing technology are specifically manifested in that the labeling process cannot be integrated into the head of the glass cutting machine, resulting in many disadvantages in the use of manual labeling.

DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are further described in detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but cannot be used to limit the scope of the present invention.

[0029] See also Figures 1 to 6 The automated glass cutting machine provided by the present invention comprises a mounting plate 1 and a rotary switching mechanism 10, a telescopic cylinder 5 is fixed to the front end of the top of the mounting plate 1, and an L-shaped frame 6 is fixedly connected to the front output end of the telescopic cylinder 5, a bearing seat 7 is fixed to the bottom of the rear end of the L-shaped frame 6, and an air blowing pipe 8 is fixed to the outer side of the end plate of the bearing seat 7, and a laser cutting head 9 is fixed to one side of the opening of the bearing seat 7, and the rotary switching mechanism 10 is rotatably installed inside the bearing seat 7.

[0030] Among them, the rotary switching mechanism 10 includes a labeling cylinder 1001, an air nozzle 1002, an ear shaft 1003, a crank 1004, a control cylinder 1005 and a connecting pin 1006. The bottom output end of the labeling cylinder 1001 is fixedly connected to the air nozzle 1002, and the labeling cylinder 1001 is rotatably installed inside the bearing seat 7 through the ear shafts 1003 of the casing on both sides. The ear shaft 1003 on one side is externally connected to the crank 1004, and the end of the crank 1004 facing away from the labeling cylinder 1001 is connected to the bottom output end of the control cylinder 1005, the top of the control cylinder 1005 is rotatably installed inside the connecting pin 1006, and the connecting pin 1006 is fixed to one side of the top end of the L-shaped frame 6.

[0031] When in use, according to the pre-arrangement, the glass is cut by the laser cutting head 9 under the three-axis movement of the cutting machine head. The laser cutting head 9 uses a high-energy-density laser beam to irradiate the glass surface to form numerous tiny wire holes along the cutting path. Thereafter, the control cylinder 1005 presses down the output end crank 1004, so that the labeling cylinder 1001 and the roller 1102 connected to the side wall through the connecting arm 1101 are located in the bearing seat 7 and rotate, thereby making the roller 1102 fit the crack on the glass surface. At this time, the air nozzle 1002 shrinks to the labeling cylinder The output end of 1001 avoids interference with the position of the roller 1102, and the built-in motor 1105 of the roller 1102 is activated to rotate the eccentric wheels 1106 at the output ends on both sides. The eccentric force generated by the rotation of the eccentric wheel 1106 causes the roller 1102 to generate power on the cracks on the surface of the glass, that is, high-frequency vibration, so that the glass breaks along the cracks to achieve the cutting purpose. The present application integrates the hammer independently set in the prior art into the cutting machine head, and can continuously perform knocking actions after laser cutting is completed to promote the breaking of the glass along the cracks, thereby effectively improving the processing efficiency.

[0032] Cross guide bars 2 are symmetrically fixed on both sides of the bottom of the mounting plate 1, and the cross guide bars 2 are slidably matched with the L-shaped frame 6. A laser generator 3 is fixed at the rear end of the top of the mounting plate 1, and the laser generator 3 is connected to the laser cutting head 9 through an optical fiber line.

[0033] A vacuum generator 4 is fixed at the middle end of the top of the mounting plate 1, and the vacuum generator 4 includes a Laval nozzle 401, a positive pressure gas source interface 402, an exhaust interface 403 and a negative pressure suction interface 404. The interior of the Laval nozzle 401 is a structure that first contracts and then expands, and one end of the Laval nozzle 401 is connected to the positive pressure gas source interface 402, the other end of the Laval nozzle 401 is connected to the exhaust interface 403 controlled by a three-way valve, and the bottom of the Laval nozzle 401 is connected to a negative pressure suction interface 404 controlled by a two-way valve, the exhaust interface 403 is connected to the air blowing pipe 8, the negative pressure suction interface 404 is connected to the air nozzle 1002, and the labeling cylinder 1001 is located on the other side of the opening of the bearing seat 7 and a composite action mechanism 11 is fixed thereto.

[0034] In some embodiments, the compound action mechanism 11 includes a connecting arm 1101 and a roller 1102, the connecting arm 1101 is fixed to the housing of the labeling cylinder 1001, and the roller 1102 is rotatably installed on the opposite surfaces of the end of the connecting arm 1101, the compound action mechanism 11 also includes a hollow shaft 1103, hollow shafts 1103 are coaxially fixed on both sides of the roller 1102, and the hollow shaft 1103 is used to thread the external power supply line into the inner cavity of the roller 1102, and the hollow shaft 1103 is rotatably matched with the axial hole clearance at the end of the connecting arm 1101, the compound action mechanism 11 also includes a retaining frame 1104, a motor 1105 and an eccentric wheel 1106, the retaining frame 1104 is fixed to the inner wall of the roller 1102, and the motor 1105 is fixed to the inner cavity of the middle hole of the retaining frame 1104, the output ends on both sides of the motor 1105 are fixedly connected to the eccentric wheel 1106, and the center of the eccentric wheel 1106 is offset from the rotation point.

[0035] After the glass is cut according to the layout, it is necessary to affix a label for displaying product information to each independent piece of finished glass. At this time, the control cylinder 1005 pulls the crank 1004 and makes the labeling cylinder 1001 rotate and reset in the bearing seat 7. The vacuum generator 4 uses the input positive pressure air source to make the air nozzle 1002 connected to the negative pressure suction interface 404 generate suction, suck the label printed by the label printer 19 and move it to the pre-layout position. At this time, the air blowing pipe 8 on the outer side of the end plate of the bearing seat 7 is connected to the exhaust interface 403 of the vacuum generator 4, and the surface of the glass to be labeled is cleaned by the output high-speed air, so that the label is more firmly adhered to the glass surface;

[0036] After that, the labeling cylinder 1001 drives the air nozzle 1002 at the output end to extend and stick the adsorbed label on the glass surface. After the labeling is completed, the control cylinder 1005 presses down the output end crank 1004 again to switch the position of the labeling cylinder 1001 so that the roller 1102 is in contact with the label pasting position. The telescopic cylinder 5 pushes and pulls the L-shaped frame 6 forward and backward to slide the horizontal guide strips 2 on both sides of the bottom of the mounting plate 1, so that the roller 1102 uses static force, that is, the dead weight of the roller 1102 during the rolling process to make the label fit tightly to the glass. By giving the roller 1102 the dual composite effects of dynamic hammering and static smoothing, the roller 1102 can satisfy the function of hammering the glass to break it along the crack, and can also satisfy the function of smoothing the label to make it firmly pasted. By avoiding interference through reasonable position design and improving performance through reasonable functional design, the functionality of the cutting head of the present application is more complete, which can meet the many functional requirements of laser cutting, knocking and breaking, positioning labeling and label smoothing.
