Description

Technical Field

[0001] The present invention relates to the technical field of glass processing equipment, and in particular to a glass cutting device for building a glass greenhouse. Background Art

[0002] The glass used in greenhouse construction usually requires very precise cutting. It is necessary to ensure that the size and shape of each piece of glass meet the requirements, so as to avoid splicing problems or structural instability caused by inaccurate cutting. Glass cutting involves sharp edges and fragments, and manual cutting may pose certain safety risks. By using a cutting device, the need for direct contact with the glass can be reduced, thereby reducing the risk of injury to workers during operation and improving workplace safety. When the existing glass cutting device performs circular cutting on glass, it cannot effectively support the inner or outer side of the area to be cut of the glass, which easily causes the edges of the cut glass to break, thereby affecting the qualification rate of the cut glass. Therefore, the present invention provides a glass cutting device for building a glass greenhouse. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment: Refer to Figures 1 - 15, a glass cutting device for building a glass greenhouse, including a bottom plate 101. An auxiliary component is arranged on the bottom plate 101. The auxiliary component includes an auxiliary slide plate one 105 slidably mounted on the bottom plate 101. An auxiliary electric cylinder 108 is fixedly mounted on the bottom plate 101. The auxiliary slide plate one 105 is fixedly mounted at the end of the piston rod of the auxiliary electric cylinder 108. An auxiliary slide plate two 106 is slidably mounted on the auxiliary slide plate one 105. An auxiliary lead screw one 111 is rotatably mounted on the auxiliary slide plate one 105. The auxiliary lead screw one 111 and the auxiliary slide plate two 106 form a screw pair. An auxiliary motor one 112 is fixedly mounted on the auxiliary slide plate one 105. The output shaft of the auxiliary motor one 112 is fixedly connected to the auxiliary lead screw one 111. An auxiliary slide seat 107 is slidably mounted on the auxiliary slide plate two 106. An auxiliary lead screw two 113 is rotatably mounted on the auxiliary slide plate two 106. The auxiliary lead screw two 113 and the auxiliary slide seat 107 form a screw pair. An auxiliary motor two 114 is fixedly mounted on the auxiliary slide plate two 106. The output shaft of the auxiliary motor two 114 is fixedly connected to the auxiliary lead screw two 113. A glass cutter 120 is rotatably mounted on the auxiliary slide seat 107. A camera is also fixedly mounted on the auxiliary slide seat 107. A switching motor 119 is fixedly mounted on the auxiliary slide seat 107. The output shaft of the switching motor 119 is fixedly connected to the glass cutter 120. A round head pressing rod 121 is fixedly arranged on the glass cutter 120. The glass cutter 120 and the round head pressing rod 121 are used to cut the glass. The end of the glass cutter 120 and the end of the round head pressing rod 121 are symmetrically arranged with respect to the axis of the switching motor 119.

[0032] Start the auxiliary electric cylinder 108 to drive the auxiliary slide plate one 105 to move upward relative to the bottom plate 101. Start the auxiliary motor one 112 to drive the auxiliary lead screw one 111 to rotate, so that the auxiliary slide plate two 106 moves along the axis of the auxiliary lead screw one 111. Start the auxiliary motor two 114 to drive the auxiliary lead screw two 113 to rotate, so that the auxiliary slide seat 107 moves along the axis of the auxiliary lead screw two 113. That is, under the action of the auxiliary electric cylinder 108, the auxiliary motor one 112, and the auxiliary motor two 114, the position of the auxiliary slide seat 107 is moved in three directions, and then the positions of the glass cutter 120 and the round head pressing rod 121 are moved. By starting the switching motor 119 to drive the glass cutter 120 and the round head pressing rod 121 to rotate synchronously, the switching of the glass cutter 120 and the round head pressing rod 121 is realized. The glass cutter 120 is used to slide on the glass surface to form a cutting line, and the round head pressing rod 121 is used to strike the glass.

[0033] Symmetrically and slidably mounted on the bottom plate 101 are support strip plates 102. Rotatably mounted on the bottom plate 101 is a double-threaded screw rod 109.

The vacuum generators 104 are communicated with the vacuum suction cups 103 on the corresponding support strip plates 102.

[0034] Start the adjustable-distance motor 110 to drive the double-threaded screw rod 109 to rotate, which makes the two support strip plates 102 move towards each other or away from each other. Under the action of the adjustable-distance motor 110, the distance between the two support strip plates 102 is adjusted, so that the glass can be placed on the two support strip plates 102. After the glass is placed on the two support strip plates 102, by starting the two vacuum generators 104, under the action of the vacuum generators 104, the vacuum suction cups 103 on the two support strip plates 102 adsorb and fix the glass.

[0035] Arranged on the bottom plate 101 are a support assembly and a stability assembly. The support assembly includes an annular support frame 126. Slidably mounted on the annular support frame 126 in a circumferential array are 8 strip-shaped racks 127. Fixedly arranged at the ends of the strip-shaped racks 127 closest to the axis of the annular support frame 126 are support short rods 128. Arranged between the 8 support short rods 128 is a driving unit. The driving unit includes an internal gear ring 129 and 8 driven gears 146. The internal gear ring 129 and the 8 driven gears 146 are both rotatably mounted on the annular support frame 126. The 8 driven gears 146 respectively form a gear-rack pair with the corresponding strip-shaped racks 127. Fixedly mounted on the driven gears 146 are transmission gears 145.

The output shaft of the support motor 122 is fixedly connected to the corresponding driven gear 146.

[0036] Start the support motor 122 to drive the corresponding driven gear 146 to rotate. Under the action of the transmission gear 145 on the driven gear 146, the internal gear ring 129 rotates, which makes the 8 transmission gears 145 rotate synchronously. Furthermore, the 8 driven gears 146 rotate synchronously, causing the 8 strip-shaped racks 127 to move synchronously towards the axis of the annular support frame 126 or away from the axis of the annular support frame 126, that is, the 8 support short rods 128 move synchronously towards the axis of the annular support frame 126 or away from the axis of the annular support frame 126.

The output shaft of the height-adjusting motor 137 is fixedly connected to the height-adjusting lead screw 138.

[0038] Start the first position-adjusting motor 115 to drive the first position-adjusting lead screw 117 to rotate, which makes the first position-adjusting sliding seat 116 move along the axis of the first position-adjusting lead screw 117. Start the second position-adjusting motor 118 to drive the second position-adjusting lead screw 124 to rotate, which makes the annular bottom frame 123 move along the axis of the second position-adjusting lead screw 124. Start the height-adjusting motor 137 to drive the height-adjusting lead screw 138 to rotate, which makes the annular bottom frame 123 move along the axis of the height-adjusting lead screw 138.

A self-locking unit is provided between the annular carriage 125 and the bar rack 127. The self-locking unit includes two limit strip plates 143. The two limit strip plates 143 are fixedly arranged on the bar rack 127 symmetrically with respect to the axis of the bar rack 127. Limit blocks 140 are symmetrically and fixedly arranged on the annular base frame 123. The limit blocks 140 are used to limit the positions of the corresponding limit strip plates 143. Circular turntables 142 are symmetrically and rotatably mounted on the annular base frame 123. A torsion spring is provided between the circular turntable 142 and the annular base frame 123. 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 turntable 142. Self-locking racks 141 are symmetrically and slidably mounted on the annular carriage 125. A spring is provided between the self-locking rack 141 and the annular carriage 125. Multiple teeth are provided on each of the circular turntables 142. The teeth on the self-locking rack 141 and the circular turntable 142 form a gear pair. Arc-shaped strip plates 139 are fixedly arranged on each of the circular turntables 142. Arc-shaped sliding grooves 144 are provided on each of the limit strip plates 143 and are used to cooperate with the arc-shaped strip plates 139. The arc-shaped strip plates 139 and the arc-shaped sliding grooves 144 are used to limit the positions between the annular carriage 125 and the bar rack 127.

[0041] In the initial position, the limit block 140 does not contact the corresponding limit strip plate 143. Both the annular carriage 125 and the annular support frame 126 are located at the position closest to the lower surface of the bottom plate 101. The spring between the annular carriage 125 and the annular support frame 126 is not compressed. The spring between the self-locking rack 141 and the annular carriage 125 is not compressed. At this time, the self-locking rack 141 does not contact the corresponding circular turntable 142. The torsion spring between the circular turntable 142 and the annular base frame 123 is not compressed. The arc-shaped strip plate 139 is in contact with the corresponding arc-shaped sliding groove 144. The upper end surface of the support long rod 133 is below the lower surface of the support short rod 128.

[0042] Start the height-adjusting motor 137 to drive the height-adjusting lead screw 138 to rotate, which causes the annular carriage 125 to move upward. Under the action of the spring between the annular carriage 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 move upward any further. At this time, the upper end surface of the support short rod 128 and the upper surface of the support strip 102 are on the same plane, and at this time, the self-locking rack 141 does not contact the teeth on the circular turntable 142. The annular carriage 125 continues to move upward, and the spring between the annular carriage 125 and the annular support frame 126 is compressed. The self-locking rack 141 moves upward synchronously. Under the action of the self-locking rack 141, the circular turntable 142 rotates, which causes the arc-shaped strip 139 to rotate. The arc-shaped strip 139 engages with the corresponding arc-shaped chute 144, and the torsion spring between the circular turntable 142 and the annular base 123 is compressed. Finally, the torsion spring between the circular turntable 142 and the annular base 123 cannot be compressed any further. At this time, the arc-shaped strip 139 and the corresponding arc-shaped chute 144 are in a fully engaged state. At this time, the upper end surface of the support long rod 133 is still below the upper end surface of the support short rod 128. The annular carriage 125 continues to move upward. At this time, the circular turntable 142 cannot rotate any further, that is, the self-locking rack 141 cannot move upward any further. At this time, the spring between the self-locking rack 141 and the annular carriage 125 is compressed, and the annular carriage 125 moves upward relative to the self-locking rack 141. At this time, the support long rod 133 moves upward synchronously. Finally, the upper end surface of the support long rod 133 and the upper end surface of the support short rod 128 are on the same plane.

[0043] Working principle: According to the size of the glass to be cut, start the distance-adjusting motor 110 to drive the double-headed threaded lead screw 109 to rotate to adjust the distance between the two support strips 102. Then place the glass to be cut on the two support strips 102. 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. Then, under the action of the camera on the auxiliary slide 107, scan and position the position of the glass.

[0044] When performing straight-line scribing on the glass, start the position-adjusting motor 115 and the position-adjusting motor 118 to adjust the position of the annular chassis 123 so that the annular chassis 123 moves to directly below the glass. Then start the support motor 122 to drive the 8 driven gears 146 to rotate synchronously, causing the 8 bar-shaped racks 127 to move synchronously in the direction close to the axis of the annular support frame 126, that is, causing the 8 support short rods 128 to move synchronously upward in the direction close to the axis of the annular support frame 126. Eventually, all 8 support short rods 128 move to the position below the glass. Then start the height-adjusting motor 137 to drive the height-adjusting screw rod 138 to rotate, causing the annular carriage 125 and the annular support frame 126 to move upward synchronously, and the 8 support short rods 128 to move upward synchronously. Eventually, all 8 support short rods 128 come into contact with the lower surface of the glass, that is, the glass is assisted in being supported by the 8 support short rods 128. The annular carriage 125 continues to move upward. At this time, the limit strip 143 contacts the limit block 140 and cannot move upward any further. Under the action of the self-locking rack 141 and the circular turntable 142, the arc-shaped strip 139 and the corresponding arc-shaped chute 144 are engaged, that is, the position of the limit strip 143 is locked, and further the position of the annular support frame 126 is fixed, that is, the position of the support short rod 128 is locked. At this time, the upper surface of the support long rod 133 is below the upper surface of the support short rod 128.

[0045] Then start the switching motor 119 to drive the glass scriber 120 and the round head pressing rod 121 to rotate synchronously, so that the glass scriber 120 is in a vertically downward state. Then start the auxiliary electric cylinder 108, the auxiliary motor 112, and the auxiliary motor 114, causing the glass scriber 120 to reciprocate 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 support short rod 128, the glass scriber 120 is prevented from causing the glass to break during the scribing process.

[0046] When circularly cutting glass, after the support strip plate 102 and the vacuum suction cup 103 complete the fixation of the glass, start the first positioning motor 115 and the second positioning motor 118. With the cooperation of the camera on the auxiliary sliding seat 107, move the axis of the annular support frame 126 to be on the same straight line as the axis of the position where the glass is to be circularly cut. Then start the support motor 122 to move the 8 support short rods 128 to the edge of the position where the glass is to be scribed. Next, start the height adjustment motor 137 to synchronously move the annular sliding frame 125 and the annular support frame 126 upward. Finally, make the support short rods 128 all contact the lower surface of the glass, that is, realize the support of the position where the glass is to be cut. The annular sliding frame 125 continues to move upward. Under the action of the limit block 140, the self-locking rack 141, the circular rotating plate 142, and the limit strip plate 143, the arc-shaped strip plate 139 engages with the corresponding arc-shaped chute 144, that is, realize the locking of the position of the annular support frame 126. At this time, the upper surface of the support long rod 133 is still below the lower surface of the support short rod 128.

[0047] Then start the auxiliary electric cylinder 108, the first auxiliary motor 112, and the second auxiliary motor 114 to make the glass cutter 120 perform circular scribing on the position where the glass is to be cut. After the circular scribing of the glass cutter 120 is completed, continue to move the position of the glass cutter 120 to make the glass cutter 120 perform multiple straight scribings on the glass within the circular scribing area. Then start the switching motor 119 to drive the glass cutter 120 and the round head pressing rod 121 to rotate, so that the round head pressing rod 121 rotates to the vertically downward state. Then, under the action of the auxiliary electric cylinder 108, the first auxiliary motor 112, and the second auxiliary motor 114, strike up and down within the circular scribing area of the glass. Under the action of the multiple straight scribings on the glass within the circular scribing area, the glass within the circular scribing area is broken. Under the action of the multiple straight scribings on the glass, the difficulty of the round head pressing rod 121 causing the glass within the circular scribing area to be broken is reduced.

[0048] When the round head pressing rod 121 needs to strike the edge of the circular scribing position, the displacement motor 136 is started to drive the displacement lead screw 135 to rotate, so that the support long rod 133 and the strip-shaped slide plate 134 move towards the direction close to the axis of the annular support frame 126. Finally, the distance between the axis of the support long rod 133 and the axis of the annular support frame 126 is equal to the distance between the axis of the support short rod 128 and the axis of the annular support frame 126. Then, the transposition motor 132 is started to drive the drive gear 131 to rotate, that is, to make the external gear ring 130 rotate relative to the annular slide 125, and the support long rod 133 and the strip-shaped slide plate 134 rotate synchronously, that is, to realize the adjustment of the position of the support long rod 133. Since there is a gap between two adjacent support short rods 128, when the round head pressing rod 121 strikes the edge position of the circular scribing area, the edge glass is easily damaged. Therefore, when the round head pressing rod 121 strikes the glass edge at the position of the gap between the two support short rods 128, the external gear ring 130 is driven to rotate, so that the support long rod 133 moves to the lower part of the position where the round head pressing rod 121 is located. Then, the height adjustment motor 137 is started to drive the annular slide 125 to continue to move upward. Finally, the upper end surface of the support long rod 133 contacts the lower surface of the glass. Under the action of the support long rod 133, when the round head pressing rod 121 strikes the glass edge, the support long rod 133 provides auxiliary support for the glass edge to prevent the round head pressing rod 121 from damaging the glass edge. Repeating the above steps, when the round head pressing rod 121 strikes the glass circular cutting position, the support long rod 133 can repeatedly support the striking position of the round head pressing rod 121, so that after the glass circular cutting position is struck, the circular cutting of the glass is realized.
