One end of the torsion spring is fixedly connected to the annular base frame 123, and the other end of the torsion spring is fixedly connected to the circular rotating plate 142. A self-locking rack 141 is symmetrically slidably installed on the annular slide 125. A spring is arranged between the self-locking rack 141 and the annular slide 125.

[0027] In the initial position, the limit block 140 is not in contact with the corresponding limit strip 143, the annular slide 125 and the annular support frame 126 are both located at the position closest to the lower surface of the base plate 101, the spring between the annular slide 125 and the annular support frame 126 is not compressed, and the spring between the self-locking rack 141 and the annular slide 125 is not compressed.

[0028] The height-adjusting motor 137 is started to drive the height-adjusting screw rod 138 to rotate, so that the annular slide 125 moves upward. Under the action of the spring between the annular slide 125 and the annular support frame 126, the annular support frame 126 and the limit strip 143 move upward synchronously, so that the limit strip 143 contacts the lower surface of the limit block 140. Under the action of the limit block 140, the limit strip 143 cannot continue to move upward. At this time, the upper end surface of the supporting short rod 128 and the upper surface of the supporting strip 102 are on the same plane, and at this time the self-locking rack 141 does not contact the teeth on the circular rotating plate 142. The annular slide 125 continues to move upward, and the spring between the annular slide 125 and the annular support frame 126 is compressed, and the self-locking rack 141 moves upward synchronously. Under the action of the self-locking rack 141, the circular rotating plate 142 rotates, so that the arc strip 139 rotates. The circular rotating plate 142 is in a state of being fully engaged with the corresponding arc slot 144. At this time, the upper end surface of the supporting long rod 133 is still below the upper end surface of the supporting short rod 128, and the annular slide 125 continues to move upward. At this time, the circular rotating plate 142 cannot continue to rotate, that is, the self-locking rack 141 cannot continue to move upward. At this time, the spring between the self-locking rack 141 and the annular slide 125 is compressed, and the annular slide 125 moves upward relative to the self-locking rack 141. At this time, the supporting long rod 133 moves upward synchronously, and finally the upper end surface of the supporting long rod 133 and the upper end surface of the supporting short rod 128 are in the same plane.

[0029] Working principle: According to the size of the glass to be cut, start the distance adjustment motor 110 to drive the double-headed threaded screw 109 to rotate and adjust the distance between the two support strips 102, and then place the glass to be cut on the two support strips 102, and then start the two vacuum generators 104 so that the vacuum suction cups 103 on the support strips 102 adsorb and fix the glass on the support strips 102, and then with the action of the camera on the auxiliary slide 107, scan and locate the position of the glass.

[0030] When the glass is marked with a straight line, the positioning motor 115 and the positioning motor 2 118 are started to adjust the position of the annular base frame 123, so that the annular base frame 123 moves to the bottom of the glass, and then the support motor 122 is started to drive the 8 driven gears 146 to rotate synchronously, so that the 8 bar racks 127 move synchronously toward the direction close to the axis of the annular support frame 126, that is, the 8 supporting short rods 128 move synchronously upward toward the direction close to the axis of the annular support frame 126, and finally the 8 supporting short rods 128 are all moved to the position below the glass, and then the height adjustment motor 137 is started to drive the height adjustment screw rod 138 to rotate, so that the annular slide 125 and the annular support frame 126 move upward synchronously, The eight short support rods 128 move upward synchronously, and finally the eight short support rods 128 all contact the lower surface of the glass, that is, the glass is auxiliary supported under the action of the eight short support rods 128, and the annular slide 125 continues to move upward. At this time, the limit strip 143 contacts the limit block 140 and cannot move upward. Under the action of the self-locking rack 141 and the circular rotating plate 142, the arc strip 139 and the corresponding arc slide groove 144 are engaged, that is, the position of the limit strip 143 is locked, and then the position of the annular support frame 126 is placed, that is, the position of the short support rod 128 is locked. At this time, the upper surface of the long support rod 133 is below the upper surface of the short support rod 128.

[0031] Then start the switching motor 119 to drive the glass cutter 120 and the round-head pressing rod 121 to rotate synchronously, so that the glass cutter 120 is in a vertical downward state, and then start the auxiliary electric cylinder 108, auxiliary motor 112, and auxiliary motor 2 114 to make the glass cutter 120 slide back and forth on the glass. With the cooperation of the camera on the auxiliary slide 107, a cutting line is formed on the glass surface. Under the action of the supporting short rod 128, the glass cutter 120 is prevented from causing the glass to break during the marking process.

[0032] When cutting the glass in a circular shape, after the support strip 102 and the vacuum suction cup 103 have completed fixing the glass, the position adjustment motor 115 and the position adjustment motor 2 118 are started, and with the cooperation of the camera on the auxiliary slide 107, the axis of the annular support frame 126 is moved to the same straight line as the axis of the glass to be cut in a circular shape, and then the support motor 122 is started to move the eight support short rods 128 to the edge of the glass to be cut in a circular shape, and then the height adjustment motor 137 is started to move the annular slide 125 and the annular The support frame 126 moves upward synchronously, and finally the supporting short rods 128 all contact the lower surface of the glass, that is, the support of the glass to be cut is achieved. The annular slide 125 continues to move upward, and under the action of the limit block 140, the self-locking rack 141, the circular rotating plate 142, and the limit strip 143, the arc strip 139 and the corresponding arc slide groove 144 engage, that is, the position of the annular support frame 126 is locked. At this time, the upper surface of the supporting long rod 133 is still below the lower surface of the supporting short rod 128.

[0033] Then, the auxiliary electric cylinder 108, the auxiliary motor 1 112, and the auxiliary motor 2 114 are started, so that the glass cutter 120 makes a circular mark on the position of the glass to be cut. After the glass cutter 120 completes the circular mark, the position of the glass cutter 120 is continued to be moved, so that the glass cutter 120 makes multiple straight line marks on the glass in the circular mark area. Then, the switching motor 119 is started to drive the glass cutter 120 and the round-headed pressing rod 121 to rotate, so that the round-headed pressing rod 121 rotates to a vertically downward state, and then the auxiliary electric cylinder 108, the auxiliary motor 1 112, and the auxiliary motor 2 114 knock up and down on the circular mark area of ​​the glass. Under the action of the multiple straight line marks on the glass in the circular mark area, the glass in the circular mark area is broken. Under the action of the multiple straight line marks on the glass, the difficulty of the round-headed pressing rod 121 causing the glass in the circular mark area to be broken is reduced.

[0034] When the round-headed pressing rod 121 needs to knock on the edge of the circular marking position, the shifting motor 136 is started to drive the shifting screw 135 to rotate, so that the supporting long rod 133 and the strip slide 134 move in the direction close to the axis of the annular support frame 126, and finally make the distance between the axis of the supporting long rod 133 and the axis of the annular support frame 126 equal to the distance between the axis of the supporting short rod 128 and the axis of the annular support frame 126, and then the shifting motor 132 is started to drive the driving gear 131 to rotate, that is, the outer gear ring 130 rotates relative to the annular slide 125, and the supporting long rod 133 and the strip slide 134 rotate synchronously, that is, the adjustment of the position of the supporting long rod 133 is realized. Since there is a gap between the two adjacent supporting short rods 128, when the round-headed pressing rod 121 knocks on the edge position of the circular marking area, it is easy to cause damage to the glass at the edge. When the round-headed pressing rod 121 strikes the edge of the glass at the gap between the two supporting short rods 128, the outer gear ring 130 is driven to rotate, so that the supporting long rod 133 moves to the bottom of the position of the round-headed pressing rod 121, and then the height adjustment motor 137 is started to drive the annular slide 125 to continue to move upward, so that the upper end surface of the supporting long rod 133 finally contacts the lower surface of the glass. Under the action of the supporting long rod 133, when the round-headed pressing rod 121 strikes the edge of the glass, the supporting long rod 133 provides auxiliary support to the edge of the glass to prevent the round-headed pressing rod 121 from causing damage to the edge of the glass. By repeating the above steps, when the round-headed pressing rod 121 strikes the circular cutting position of the glass, the supporting long rod 133 can repeatedly support the striking position of the round-headed pressing rod 121, so that after completing the striking of the circular cutting position of the glass, the circular cutting of the glass is achieved.

[0035] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
