Description

Technical Field

[0001] The invention belongs to the technical field of glass processing, and in particular relates to a glass transmission device. Background Art

[0002] The glass plate processing involves transmission and chamfering processes. Glass transmission generally uses a conveyor belt, which transfers the glass to the processing area for chamfering. In order to improve the efficiency of glass processing, the conveyor belt needs to be operated at a faster speed. When the conveyor belt runs at a faster speed, the heavy weight of the glass causes its movement inertia to be greater, and the glass is prone to slipping on the conveyor belt, which may cause the glass to be scratched. In order to prevent the glass from being scratched, an anti-slip film needs to be installed on the glass, which increases the cost of glass processing while increasing the glass processing steps. In addition, the manual operation efficiency of adding an anti-slip film to the glass is low.

[0003] In order to improve the efficiency of glass processing, it is necessary to perform stripping processing on the glass during the glass transmission process. This requires that the glass arrives at the processing area in a correct and accurate position on the conveyor belt. It is necessary to set an adjustment structure for adjusting the position of the glass in the area where the glass is initially placed on the conveyor belt, so that the glass on the conveyor belt moves to the processing area in the correct position, such as the patent with the published application number CN201720317946.X. However, for a fast-running conveyor belt, there is an impact force when the adjustment structure contacts the glass, and the impact force increases with the increase of the conveyor belt running speed, which often causes the glass to break, thereby increasing the loss of processing materials for glass processing.

[0004] The widths of the glass to be processed are various. In order to effectively adapt to the width of the glass and effectively reduce the cost of the conveyor belt, the conveyor belt is two narrow conveyor belts symmetrically distributed on the left and right, which involves the spacing adjustment of the two narrow conveyor belts to adapt to the width of the glass. The spacing adjustment structure is generally arranged on the ground as a transverse track that enables the two conveyor belts to move laterally. Because the transverse spacing adjustment range of the two narrow conveyor belts to adapt to the width of the glass is large, the track length is longer, so more space is needed on the ground for arranging the track, which squeezes the layout space of other structures such as wiring and glass clamps.

[0005] In addition, previous glass processing equipment usually uses a handle to rotate to control the height of the pressure plate to clamp the glass on the conveyor belt and uses manual adjustment to adjust the tightness of the conveyor belt. These operations are inefficient. In addition, because the tensile performance of the conveyor belt used for applying pressure above the glass is weak, it is necessary to adjust the tightness and downward pressure height of the pressure conveyor belt multiple times when replacing glass of different thicknesses. The operation is cumbersome and inefficient.

[0006] The present invention designs a glass transmission device to solve the above problems. Summary of the invention

[0007] Based on this, it is necessary to provide a glass transmission device for the problems existing in the current glass transmission equipment. The present invention provides a layer of anti-scratch film belt on the working surface of the second transmission belt, which can be used cyclically and uninterruptedly with the movement of the second transmission belt and can effectively absorb and pull the flat glass with the participation of the atomizing nozzle, so as to avoid relative wear and scratches between the flat glass and the second transmission belt due to direct contact between the two. At the same time, the use of the anti-scratch film belt that moves synchronously and at a constant speed with the second transmission belt and is used cyclically and uninterruptedly can save the process of manually setting an anti-slip film on the flat glass, improve the glass processing efficiency and effectively reduce the labor cost of flat glass processing. The third motor in the clamping assembly of the present invention has only a small power change when the flat glass passes due to the operation of the fourth motor, which effectively protects the third motor and reduces the probability of the third motor failing due to frequent power changes. The first bracket with inclined rod support where the two groups of narrow strip first transmission belts of the transmission assembly of the present invention are located has a large spacing adjustment range due to the longitudinal staggered arrangement. At the same time, the total lateral size of the first guide seat where the two groups of first transmission belts are located is short, which saves a lot of space and provides sufficient space for setting other related structures. When the two alignment wheels on each side of the alignment assembly of the present invention come into contact with the flat glass transmitted from the first conveyor belt, the swing rods on which they are located will swing adaptively and will not collide strongly with the flat glass moving rapidly with the first conveyor belt, thereby adjusting the position of the flat glass in an abnormal position state on the first conveyor belt, so that the flat glass is effectively fixed on the first conveyor belt by the second conveyor belt in the correct position state and effectively processed in the processing area, avoiding large processing errors caused by changes in the position state of the flat glass during processing. The clamping assembly in the present invention is automatically driven by the third motor and the fourth motor, while the tensioning assembly in the clamping assembly is driven by an electric push rod, which realizes the automation of clamping and fixing the flat glass on the first conveyor belt and tensioning the second conveyor belt, effectively improving the operating efficiency of this process. At the same time, since the tensioning assembly in the clamping assembly of the present invention has good elasticity of the second conveyor belt, there is no need to frequently adjust the tightness of the second conveyor belt and the downward pressure height of the working surface when frequently replacing flat glass with not very large thickness differences. The elastic deformation of the second conveyor belt itself is sufficient to effectively clamp and fix the glass with not very large thickness differences, thereby effectively improving the operating efficiency of the clamping assembly in clamping flat glass with not very large thickness differences.

The clamping assembly in the present invention is automatically driven by the third motor and the fourth motor, while the tensioning assembly in the clamping assembly is driven by an electric push rod, which realizes the automation of clamping and fixing the flat glass on the first conveyor belt and tensioning the second conveyor belt, effectively improving the operating efficiency of this process. At the same time, the tensioning assembly in the clamping assembly of the present invention does not need to frequently adjust the tightness of the second conveyor belt and the pressing height of the working surface when frequently replacing flat glass with a small thickness difference, because the second conveyor belt has good elasticity. Only the elastic deformation of the second conveyor belt itself can meet the effective clamping and fixing of glass with a small thickness difference, thereby effectively improving the operating efficiency of the clamping assembly in clamping flat glass with a small thickness difference.

[0072] In a further embodiment, Fig.19 , Fig. 20 As shown, the second rack 403 is slidably arranged in the second guide sleeve 402 on the fifth bracket 401, the two second racks 403 are meshed with the fourteen gears 404 on the output shaft of the sixth motor 405, the sixth motor 405 is arranged on the fifth bracket 401, a vertical rod 406 is arranged at the outer end of the second rack 403, a first fixed shaft 407 is arranged at the upper end of the vertical rod 406, a ring sleeve 416 is arranged at the end of the first fixed shaft 407, a vertical rotating shaft 417 is rotatably arranged in the ring sleeve 416, the upper end of the rotating shaft 417 is fixedly connected to the middle part of the corresponding swing rod 418, and the positioning wheel 420 is rotatably arranged on the second fixed shaft 419 at the corresponding end of the swing rod 418.

[0073] In a further embodiment, Fig.19 , Fig. 20 As shown, the positioning assembly 421 includes a rotating sleeve 408 rotatably set on the first fixed shaft 407, and a threaded sleeve 409 is set on the rotating sleeve 408. The threaded sleeve 409 is threadedly connected to a sliding sleeve 413 axially sliding on the first fixed shaft 407, and two connecting rods 414 perpendicular to the first fixed shaft 407 are symmetrically set at the end of the threaded sleeve 409, and two limiting rods 415 cooperating with the rocker rod 418 are symmetrically set at the ends of the two connecting rods 414, and a fifteenth gear 410 is set on the threaded sleeve 409, and the fifteenth gear 410 is meshed with a sixteenth gear 411 on the output shaft of the seventh motor 412, and the seventh motor 412 is fixed to the corresponding vertical rod 406 by bolts.

[0074] The present invention sets a layer of anti-scratch film belt 203 on the working surface of the second conveyor belt 209, which can be used cyclically and uninterruptedly during the movement of the second conveyor belt 209 and can effectively absorb and pull the flat glass 501 with the participation of the atomizing nozzle 224, so as to avoid relative wear and scratches between the flat glass 501 and the second conveyor belt 209 due to direct contact between the two. At the same time, the use of the anti-scratch film belt 203 that moves synchronously with the second conveyor belt 209 at a constant speed and is used cyclically and uninterruptedly can save the process of manually setting an anti-slip film on the flat glass 501, improve the glass processing efficiency and effectively reduce the labor cost of processing the flat glass 501. The third motor 208 in the clamping assembly 200 of the present invention has only a small power change when the flat glass 501 passes due to the operation of the fourth motor 223, which effectively protects the third motor 208 and reduces the probability of failure of the third motor 208 due to frequent power changes. The first bracket 101 with inclined rod support where the two groups of narrow strip-type first conveyor belts 105 of the transmission assembly 100 of the present invention are located has a large spacing adjustment range due to the longitudinal staggered arrangement. At the same time, the total lateral dimension of the first guide seat 110 where the two groups of first conveyor belts 105 are located is short, which saves a lot of space and provides sufficient space for setting other related structures. When the two aligning wheels 420 on each side of the alignment assembly 400 of the present invention contact with the flat glass 501 transmitted from the first conveyor belt 105, the swing rod 418 where they are located will swing adaptively and will not have a strong impact with the flat glass 501 moving rapidly with the first conveyor belt 105, thereby adjusting the position state of the flat glass 501 in an abnormal position state on the first conveyor belt 105, so that the flat glass 501 is effectively fixed on the first conveyor belt 105 by the second conveyor belt 209 in the correct position state and effectively processed in the processing area, avoiding large processing errors caused by changes in the position state of the flat glass 501 during the processing process. The clamping assembly 200 of the present invention is automatically driven by the third motor 208 and the fourth motor 223, while the tensioning assembly 227 in the clamping assembly 200 is driven by the electric push rod 212, which realizes the automation of clamping and fixing the flat glass 501 on the first conveyor belt 105 and tensioning the second conveyor belt 209, effectively improving the operating efficiency of this process. At the same time, the tensioning assembly 227 in the clamping assembly 200 of the present invention does not need to frequently adjust the tightness of the second conveyor belt 209 and the pressing height of the working surface when frequently replacing the flat glass 501 with a small thickness difference, because the second conveyor belt 209 has good elasticity. Only the elastic deformation of the second conveyor belt 209 itself can meet the effective clamping and fixing of the glass with a small thickness difference, thereby effectively improving the operating efficiency of the clamping assembly 200 for clamping the flat glass 501 with a small thickness difference.

[0075] The operation process of the present invention is as follows:

[0076] In the initial state, the anti-scratch film belt 203 in the clamping assembly 200 has a gap smaller than the thickness of the flat glass 501 with the first conveyor belt 105 under the action of the pressing plate 216, the anti-scratch film belt 203 and the second conveyor belt 209 are both in a taut state, the distance between the two second fixed shafts 419 in the alignment assembly 400 is the largest, the two swing rods 418 and the alignment wheels 420 on the swing rods 418 do not form a barrier to the flat glass 501 that moves with the first conveyor belt 105 and whose state is unknown and uncertain, and there is a certain distance between the two limit rods 415 on each sliding sleeve 413 and the corresponding swing rod 418. All positioning springs 115 in the transmission assembly 100 are in a compressed state, the two first conveyor belts 105 are symmetrically distributed, and the distance between the compression spring ring 113 in the middle of the crossbar 112 and the corresponding two first guide sleeves 102 is equal.

[0077] When the present invention is used to process the flat glass 501, Fig. 22 As shown, firstly, the lateral spacing between the two first conveyor belts 105 in the conveying assembly 100 is adjusted according to the width size of the batch of flat glass 501 to be processed, and the second motor 120 is started. The first screw 119, two third gears 121 and fourth gear 122 connected to the second motor 120 drive the other first screw 119 on the corresponding first guide seat 110 to rotate in the same direction and at a constant speed. The other first screw 119 drives the two first screws 119 on the other first guide seat 110 to rotate in the same direction and at a constant speed through the sprocket 123, the chain 124, the two third gears 121 and the fourth gear 122 on the other first guide seat 110. The first slide seats 118 at the lower ends of the inclined legs of the two first brackets 101 slide in the opposite direction at a constant speed. Under the action of the two cross bars 112 and the positioning springs 115 on the cross bars 112, the two first conveyor belts 105 on the two first brackets 101 move in the opposite direction at a constant speed by a certain amplitude, thereby completing the spacing adjustment between the two first conveyor belts 105.

[0078] Then, the distance between the two pressing assemblies 200 is adjusted so that the distance between the two pressing assemblies 200 is equal to the distance between the two first conveyor belts 105, ensuring that the two second conveyor belts 209 and the anti-scratch film belt 203 are respectively located directly above the two first conveyor belts 105. At the same time, the gap between the anti-scratch film belt 203 and the first conveyor belt 105 is adjusted according to the thickness of the flat glass 501 to be processed, ensuring that the anti-scratch film belt 203 can effectively absorb and traction the flat glass 501 under the pressure of the second conveyor belt 209.

[0079] The fifth motor 308 is started, and the fifth motor 308 drives the two second brackets 201 to move in the opposite direction at a certain speed through the thirteenth gear 307, the twelve gear 306, the second transmission shaft 305, the two eleventh gears 304, the four first gears 107 and the four fourth slides 225, so that the two anti-scratch film belts 203 are located just above the corresponding first conveyor belt 105 under the pressure of the corresponding second conveyor belt 209.

[0080] After the spacing between the two clamping assemblies 200 is adjusted, the fourth motor 223 and the electric push rod 212 in each clamping assembly 200 are started, and the two electric push rods 212 in each clamping assembly 200 loosen or further tighten the second conveyor belt 209 through the corresponding two second slides 211, the second roller 205 and the third conveyor roller 204. The fourth motor 223 rotates through the tenth gear 222, the ninth gear 221, the first transmission shaft 220, the two eighth gears 219, the two seventh gears 218 and the two second screws 217 to drive the two third slides 214 to move in the same direction and at a constant speed in the vertical direction by a certain amplitude. The two third slides 214 respectively drive the pressure plate 216 to move downward or upward by a certain amplitude through the corresponding third bracket 215 and keep the second conveyor belt 209 in a taut state, so that the gap between the anti-scratch film belt 203 and the first conveyor belt 105 under the action of the second conveyor belt 209 finally matches the thickness of the flat glass 501 to be processed.

[0081] After the adjustment of the transmission component 100 and the two clamping components 200 is completed, the two first motors 109 are started to operate, and the two first motors 109 synchronously drive the two first transmission belts 105 to move at a constant speed. The two first motors 109 respectively drive the two first transmission belts 105 to move in the same direction and at a constant speed through the corresponding second gear 108, the first gear 107, the first roller 106 and the first transmission roller 103.

[0082] After the two first conveyor belts 105 run smoothly at the same speed and in the same direction, the flat glass 501 to be processed is placed on the two first conveyor belts 105 in sequence and at intervals by a robotic arm. The flat glass 501 placed on the first conveyor belt 105 moves toward the alignment component 400 with the first conveyor belt 105 in an uncertain position state.

[0083] like Fig.21As shown, when the flat glass 501 reaches between the two pairs of alignment wheels 420 on the two swing rods 418 of the alignment component 400 in an uncertain position state, the sixth motor 405 is started, and the sixth motor 405 drives the two second racks 403 to move toward each other through the fourteenth gear 404, and the two second racks 403 respectively drive the alignment wheels 420 on the corresponding swing rods 418 to approach the corresponding sides of the flat glass 501. In the process of the two swing rods 418 approaching the corresponding sides of the flat glass 501, a certain alignment wheel 420 on each swing rod 418 contacts the corresponding side of the flat glass 501 first, and the two swing rods 418 swing adaptively under the action of the flat glass 501, and finally the two alignment wheels 420 on the swing rods 418 contact the corresponding sides of the flat glass 501, and the two pairs of alignment wheels 420 on the two swing rods 418 clamp the flat glass 501 that is still in the initial position state without being constrained.

[0084] Then, the two seventh motors 412 in the alignment component 400 are started. The two seventh motors 412 drive the corresponding two limiting rods 415 to quickly approach the rocking rod 418 and resist against the rocking rod 418 through the corresponding sixteenth gear 411, fifteenth gear 410, screw sleeve 409, sliding sleeve 413, and connecting rod 414. The two rocking rods 418 are swung to a state parallel to the transmission direction of the first conveyor belt 105 under the action of the corresponding two limiting rods 415. The two rocking rods 418 simultaneously pull the flat glass 501 on the first conveyor belt 105 to rotate a certain angle and complete the alignment through the two pairs of alignment wheels 420 thereon. After the flat glass 501 is aligned, the sixth motor 405 is started to drive the two rocking rods 418 to drive the two pairs of alignment wheels 420 to separate from the corresponding sides of the flat glass 501. The aligned flat glass 501 moves to the bottom of the second conveyor belt 209 along the first conveyor belt 105.

[0085] When the flat glass 501 moves to the second conveyor belt 209, the third motors 208 in the two clamping assemblies 200 are started, and the two third motors 208 respectively drive the second conveyor belt 209 to run through the corresponding sixth gear 207, the fifth gear 206, the second roller 205 and the third conveying roller 204, and the second conveyor belt 209 drives the anti-scratch film belt 203 to move synchronously. At the same time, the atomizing nozzle 224 in each clamping assembly 200 sprays water mist onto the corresponding anti-scratch film belt 203 to moisten it, so that the anti-scratch film belt 203 in contact with the flat glass 501 forms a good adsorption and traction for the flat glass 501. Since the anti-scratch film belt 203 is arranged between the second conveyor belt 209 and the flat glass 501, the flat glass 501 will not be scratched by friction during the movement of being pressed and fixed on the first conveyor belt 105 by the second conveyor belt 209.

[0086] If there is only the third motor 208 but no fourth motor 223 in the clamping assembly 200: when there is no flat glass 501 on the first conveyor belt 105, the third motor 208 outputs a certain power to drive the first conveyor belt 105 to run at a constant speed. When a flat glass 501 passes between the first conveyor belt 105 and the second conveyor belt 209, the friction between the flat glass 501 and the first conveyor belt 105 increases. In order to ensure the constant speed movement of the first conveyor belt 105, the output power of the third motor 208 needs to be increased, so that the output power of the third motor 208 changes frequently, resulting in a large loss or damage of the third motor 208.

[0087] If the clamping assembly 200 includes both the third motor 208 and the fourth motor 223: when there is no flat glass 501 on the first conveyor belt 105, the third motor 208 outputs a certain power to drive the first conveyor belt 105 to run at a constant speed, while the fourth motor 223 does not run. When a flat glass 501 passes between the first conveyor belt 105 and the second conveyor belt 209, the friction between the flat glass 501 and the first conveyor belt 105 increases, the output power of the third motor 208 increases to ensure that the first conveyor belt 105 runs at a constant speed, and the fourth motor 223 runs and participates in the work, so that the power increase of the third motor 208 is not very large, thereby reducing the probability of failure of the third motor 208. In this case, in order to ensure that the second conveyor belt 209 can press and fix the flat glass 501 on the first conveyor belt 105 under the joint action of the tensioning assembly 227 and the pressing plate 216, the second conveyor belt 209 must have good elasticity, so that the second conveyor belt 209 is squeezed or stretched when it contacts the flat glass 501 because it needs to provide effective traction for the flat glass 501. The squeezing or stretching deformation of the second conveyor belt 209 will cause relative movement between it and the flat glass 501, thereby causing the flat glass 501 to be scratched in the area where it contacts the second conveyor belt 209. As the flat glass 501 contacts the second conveyor belt 209, the flat glass 501 is likely to be scratched. As the contact surface of the belt 209 increases, the deformation area of ​​the second conveyor belt 209 due to extrusion or stretching becomes larger, and the area of ​​relative movement between the second conveyor belt 209 and the flat glass 501 becomes larger, resulting in more serious wear or scratches on the flat glass 501 during its passage through the second conveyor belt 209. Based on this, the present invention provides a layer of anti-scratch film belt 203 on the working surface of the second conveyor belt 209, which can be circulated and uninterruptedly used during the movement of the second conveyor belt 209 and can effectively absorb and pull the flat glass 501 with the participation of an atomizing nozzle 224, thereby avoiding relative wear and scratches between the flat glass 501 and the second conveyor belt 209 due to direct contact between the two.

[0088] like Fig. 22As shown, a sliding bearing 116 is provided between the cross bar 112 in the transmission component 100 and the first guide sleeve 102 on the first bracket 101, so as to ensure that the interaction force generated by the hinge between the inclined legs of the first bracket 101 and the corresponding first slide seat 118 is transmitted to the cross bar 112, thereby avoiding deformation of the hinge between the first bracket 101 and the first slide seat 118, effectively extending the service life of the first bracket 101 in the transmission component 100 and effectively reducing the maintenance cost.
