Description

Technical Field

[0001] This invention relates to the field of glass engraving technology, specifically a novel glass engraving machine. Background Technology

[0002] Glass engraving machines are a type of CNC machine tool, also known as glass carving machines, glass drilling machines, glass edging machines, irregular glass cutting machines, glass grooving machines, and precision glass forming machines. This concept was first proposed and realized by Shenzhen Yuanyang CNC. Glass engraving machines are mainly used for the fine processing and irregular cutting of various ultra-thin glasses. The technology is very mature. Due to the development and demand of the future consumer electronics market, more and more digital electronic displays are using glass as the display screen or touch screen, and the market for glass engraving machines is becoming increasingly huge.

[0003] Chinese patent CN219153333U discloses a positioning device for a glass engraving machine, including a positioning mechanism comprising a horizontal plate, an engraving head, a first motor, a vertical block, and a clamping plate. The engraving head is positioned above the horizontal plate, and the first motor is fixedly installed at the bottom of the horizontal plate. In this invention, the first motor drives a moving plate via a first screw, the moving plate presses against a connecting rod via the vertical block, the connecting rod drives the clamping plate via the horizontal block, the clamping plate moves two cylinders to stretch a spring, and the clamping plate fixes the glass. A second electric telescopic rod drives the engraving head downwards to engrave the glass. The first electric telescopic rod adjusts the front-to-back position of the engraving head, and the second motor drives the engraving head left-to-right via a second screw.

[0004] This glass engraving machine can position glass of different specifications to avoid deviations in the engraving due to off-center positioning, thus improving the yield rate of glass engraving. However, manual loading can easily cause scratches on the glass surface, which can still reduce the quality of the product.

[0024] The glass plates to be finely engraved are stacked one on top of the other and placed into the U-shaped material frame 10. The glass plates fall under the action of gravity and finally fall into the receiving cylinder 9. The servo motor 7 is powered on and drives the feeding mechanism 8 to work.

[0025] Reference Figure 1-5This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the moving component 4 includes a lead screw 41, a guide slide rod 42, a movable block 43, a transverse cylinder 44, a connecting plate 45, and a lifting cylinder 46. The two ends of the lead screw 41 are rotatably connected to the top of the bracket 2, and one end of the lead screw 41 is fixedly connected to the servo motor 3.

[0026] Reference Figure 1 When the servo motor 3 is powered on, it drives the lead screw 41 to rotate.

Several air nozzles 61 are fixedly connected to the inner side of the vertical inclined plates 63. The air nozzles 61 are connected to an air pump through pipes. The air nozzles 61 blow air towards the surface of the material tray 13, thereby blowing away the glass shards being carved. The blown-away glass shards are blocked by the cleaning baffle 6 and finally fall into the collection box 64 for collection.

[0028] Specifically, the feeding mechanism 8 includes a transmission disc 81, a transmission shaft 82, a sector plate 83, a rotating connecting rod 84, a cylindrical pin 85, an active connecting rod 86, a transmission connecting rod 87, a receiving assembly 88, and a support plate 89. Two transmission shafts 82 are provided and are coaxially fixedly connected to both ends of the receiving cylinder 9. The transmission shafts 82 are rotatably connected to the support plate 11. One transmission shaft 82 is fixedly connected to a rotary joint 14, and the other transmission shaft 82 is fixedly sleeved on the side away from the receiving cylinder 9, where the transmission disc 81 slides against the sector plate 83. One side of the sector plate 83... One end of the active connecting rod 86 is fixedly connected to the end face, and the other end of the active connecting rod 86 is fixedly connected to the cylindrical pin 85. The sector plate 83 and the active connecting rod 86 are both fixedly connected to the output shaft of the servo motor 7. The output shaft of the servo motor 7 is rotatably connected to the bracket 11, and the end of the output shaft is fixedly connected to one end of the rotating connecting rod 84. The other end of the rotating connecting rod 84 is hinged to one end of the transmission connecting rod 87. The other end of the transmission connecting rod 87 is hinged to the receiving assembly 88. The receiving assembly 88 is rotatably connected to the top of the support plate 89. The bottom end of the support plate 89 is fixedly connected to the worktable 1.

[0029] Furthermore, the transmission disc 81 has several crescent-shaped openings 811 on its periphery, which are evenly distributed around the circumference. The crescent-shaped openings 811 slide against the sector plate 83. Between two adjacent crescent-shaped openings 811, there is a toggle opening 812, which slides and engages with the cylindrical pin 85.

[0030] Furthermore, the active connecting rod 86 is located in the middle of the opening of the sector plate 83. The length direction of the active connecting rod 86 is perpendicular to the length direction of the rotating connecting rod 84. The rotating connecting rod 84 is movably disposed between a second bracket 11 and the end wall of the receiving cylinder 9. The second bracket 11 has an inverted L-shaped structure.

[0031] Furthermore, the receiving assembly 88 includes a first actuating link 881, a support shaft 882, a first support plate 883, a second actuating link 884, a connecting column 885, a receiving plate 886, a first suction cup 887, a hinge block 888, and a sliding groove 889. Two first support plates 883 are provided and their bottoms are fixedly connected to the worktable 1. The first support plate 883 is located between the second support plate 89 and the second bracket 11. The top of the first support plate 883 is rotatably connected to both sides of the support shaft 882. One end of the support shaft 882 is fixedly connected to one end of the first actuating link 881. The other end of 881 is hinged to the transmission connecting rod 87. The two sides of the support shaft 882 are respectively fixedly connected to one end of the second actuating connecting rod 884. The other end of the second actuating connecting rod 884 is hinged to one side of the connecting column 885. The other side of the connecting column 885 is provided with a sliding opening 889. The hinge block 888 is slidably engaged in the sliding opening 889. The hinge block 888 is respectively hinged to the top of the second support plate 89. The end of the connecting column 885 away from the sliding opening 889 is fixedly connected to the receiving plate 886. Several suction cups 887 are fixedly installed on the end face of the receiving plate 886 away from the connecting column 885.

[0032] Reference Figure 1-5When servo motor 7 is powered on, it drives the feeding mechanism 8. The sector plate 83, rotating connecting rod 84, and active connecting rod 86 of the feeding mechanism 8 all rotate under the drive of servo motor 7. After the active connecting rod 86 rotates to the position of the transmission disk 81, the cylindrical pin 85 is engaged in the actuating port 812. The continuously rotating active connecting rod 86, in conjunction with the cylindrical pin 85, actuates the transmission disk 81. The transmission disk 81 drives the fixed transmission shaft 82 to rotate, and the transmission shaft 82 drives the fixed receiving cylinder 9 to rotate, causing the groove 91 with the glass plate to rotate to the vertical position, that is, to receive the material from the receiving assembly 88. With plates 886 facing each other, the rotating connecting rod 84, which rotates in a circular motion, drives the hinged transmission connecting rod 87 to move back and forth. The transmission connecting rod 87 drives the hinged actuating connecting rod 881 to swing back and forth. The actuating connecting rod 881 drives the fixed support shaft 882 to rotate back and forth. The support shaft 882 drives the actuating connecting rod 884 to swing back and forth. The actuating connecting rod 884 drives the hinged connecting column 885 to swing back and forth. When the connecting column 885 swings to a horizontal position, it drives the fixed receiving plate 886 to adhere to the groove 91. That is, the suction cup 887 adsorbs the glass plate in the groove 91, and then... Figure 1 As shown, the glass plate is swung clockwise to a vertical position, that is, the receiving plate 886 is moved directly above the material tray 13, and the glass plate falls into the material tray 13.

[0033] Specifically, the receiving cylinder 9 has several grooves 91 evenly distributed around its circumference. Several suction cups 92 are fixedly installed on the inner wall of each groove 91. Several cylindrical grooves 93 are formed on both sides of the arc-shaped surface of the receiving cylinder 9, located on either side of the center of each groove 91. A feeding assembly 101 is slidably engaged with each cylindrical groove 93 and is movably positioned at the bottom of the material frame 10. Glass plates requiring fine carving are stacked vertically and sequentially placed into the U-shaped material frame 10. The glass plates fall under gravity and finally into the grooves 91 of the receiving cylinder 9. There are four or eight grooves 91, and the suction cups 92 then adhere to the glass plates to prevent them from detaching.

[0034] Furthermore, the feeding assembly 101 includes a movable cavity 1011, a limiting plate 1012, a cylindrical locking block 1013, a spring 1014, an airbag 1015, a rubber sheet 1016, and an L-shaped cavity 1017. The movable cavity 1011 is opened on both sides of the bottom of the material frame 10. The limiting plate 1012 is slidably sleeved inside the movable cavity 1011. One end of the limiting plate 1012 is fixedly connected to the cylindrical locking block 1013. The end of the cylindrical locking block 1013 slides out of the movable cavity 1011 and engages with the cylindrical groove 93. In conjunction with this, one end of a spring 1014 is fixedly connected to one side of the other end of the limiting plate 1012, and the other end of the spring 1014 is fixedly connected to the inner wall of the movable cavity 1011. An airbag 1015 is abutted against the other side of the other end of the limiting plate 1012. The airbag 1015 is installed in the L-shaped cavity 1017. One side of the L-shaped cavity 1017 is connected to the movable cavity 1011. A rubber sheet 1016 is fixedly connected to the other end of the L-shaped cavity 1017. The rubber sheet 1016 is located inside the material frame 10.

[0035] Servo motor 7 is powered on, driving the feeding mechanism 8. The sector plate 83, rotating connecting rod 84, and active connecting rod 86 of the feeding mechanism 8 all rotate under the drive of servo motor 7. After the active connecting rod 86 rotates to the position of the transmission disk 81, the cylindrical pin 85 engages in the actuating port 812. The continuing rotation of the active connecting rod 86, in conjunction with the cylindrical pin 85, actuates the transmission disk 81. The transmission disk 81 drives the fixed transmission shaft 82 to rotate, and the transmission shaft 82 drives the fixed receiving device to rotate. As cylinder 9 rotates, the material receiving cylinder 9 rotates, causing the material discharging assembly 101 to disengage from the cylindrical groove 93. The cylindrical locking block 1013 retracts into the movable cavity 1011, simultaneously causing the fixed limiting disc 1012 to move. The limiting disc 1012 compresses the airbag 1015, causing part of the airbag 1015 located in the movable cavity 1011 to deflate, while the airbag 1015 located in the L-shaped cavity 1017 expands. Due to the high elasticity and strong deformation capacity of the rubber sheet 1016, the airbag 101... 5. During expansion, the rubber sheet 1016 bulges into the material frame 10. After bulging, the rubber sheet 1016 contacts the bottom glass plate of the material frame 10, thus clamping the glass plate to prevent it from falling and keeping the bottom glass plate inside the material frame 10. When the receiving cylinder 9 rotates, the glass plate inside the material frame 10 will not contact the outer wall of the receiving cylinder 9, preventing scratches on the glass plate. When the groove 91 of the receiving cylinder 9 rotates to the bottom of the material frame 10, the fan-shaped plate 83 then... The glass slides against the crescent-shaped opening 811, and at the same time, the cylindrical pin 85 disengages from the actuating opening 812. Simultaneously, the cylindrical block 1013 of the feeding assembly 101 pops out under the elastic force of the spring 1014, and the cylindrical block 1013 re-engages into the cylindrical groove 93. At the same time, the reverse force of the glass pushes against the rubber sheet 1016 to return, thereby restoring the deflated airbag 1015 and allowing the new glass plate to fall into the groove 91 again for feeding, thus realizing the sequential feeding of individual glass plates. Example

[0036] Reference Figure 1-5 This is the third embodiment of the present invention. Based on the above two embodiments, in use, the glass plates to be precisely carved are stacked one on top of the other and placed into the U-shaped material frame 10. The glass plates fall under the action of gravity and finally fall into the groove 91 of the receiving cylinder 9. The groove 91 has four or eight openings. Then, the glass plates are adsorbed and prevented from falling off by the suction cup 92. The servo motor 7 is powered on and drives the feeding mechanism 8. The fan-shaped plate 83, the rotating connecting rod 84, and the active connecting rod 86 of the feeding mechanism 8 all rotate under the drive of the servo motor 7. After the active connecting rod 86 rotates to the position of the transmission disk 81, the cylindrical pin 85 is engaged in the actuating port 812. The continuously rotating active connecting rod 86, in conjunction with the cylindrical pin 85, actuates the transmission disk 81. The rotation of the transmission disc 81 drives the fixed transmission shaft 82 to rotate, which in turn drives the fixed receiving cylinder 9 to rotate. The rotation of the receiving cylinder 9 causes the discharging assembly 101 to disengage from the cylindrical groove 93, and the cylindrical clamping block 1013 retracts into the movable cavity 1011. Simultaneously, it drives the fixed limiting disc 1012 to move, compressing the airbag 1015. Part of the airbag 1015 located in the movable cavity 1011 deflates, while the airbag 1015 located in the L-shaped cavity 1017 expands. Because the rubber sheet 1016 has high elasticity and strong deformation capacity, the expansion of the airbag 1015 causes the rubber sheet 1016 to bulge towards the material frame 10. After bulging, the rubber sheet 1016 abuts against the bottom glass plate of the material frame 10, thus impacting the glass. The glass plate is clamped to prevent it from falling, keeping the lowest glass plate within the material frame 10. When the receiving cylinder 9 rotates, the glass plate inside the material frame 10 will not contact the outer wall of the receiving cylinder 9, preventing scratches on the glass plate. When the next groove 91 of the receiving cylinder 9 rotates to the bottom of the material frame 10, the fan-shaped plate 83 slides against the crescent-shaped opening 811 again. Simultaneously, the cylindrical pin 85 disengages from the actuating port 812, and the cylindrical locking block 1013 of the discharging assembly 101 pops out under the elastic force of the spring 1014. The cylindrical locking block 1013 re-engages into the cylindrical groove 93, and the reverse force of the glass pushes against the rubber sheet 1016 to return to its original position. Simultaneously, the self-recovering ability of the airbag 1015 causes the deflated airbag 1015 to recover, allowing a new glass plate to be placed. The glass plate falls into the groove 91 for feeding. The receiving cylinder 9 rotates, causing the groove 91 with the glass plate to rotate to a vertical position, that is, opposite to the receiving plate 886 of the receiving assembly 88. The rotating connecting rod 84 drives the hinged transmission connecting rod 87 to move back and forth. The transmission connecting rod 87 drives the hinged actuating connecting rod 1 881 to swing back and forth. The actuating connecting rod 1 881 drives the fixed support shaft 882 to rotate back and forth. The support shaft 882 drives the actuating connecting rod 2 884 to swing back and forth. The actuating connecting rod 2 884 drives the hinged connecting column 885 to swing back and forth. When the connecting column 885 swings to a horizontal position, it causes the fixed receiving plate 886 to adhere to the groove 91, that is, the suction cup 1 887 adsorbs the glass plate in the groove 91, and then... Figure 1As shown, the glass plate swings clockwise to a vertical position, that is, the receiving plate 886 moves directly above the material tray 13, and the glass plate falls into the material tray 13. The linear motor 12 works, driving the material tray 13 to move into the cleaning baffle 6. The moving component 4 drives the engraving head 5 to move, and the engraving head 5 performs fine engraving on the glass plate. At the same time, the air nozzle 61 is connected to the air pump through the pipeline. The air nozzle 61 blows air towards the surface of the material tray 13, thereby blowing away the finely engraved glass shards. The blown-away glass shards are blocked by the cleaning baffle 6 and finally fall into the collection box 64 for collection.
