Description

[0002] In the glass production process, the two sides of the glass need to be polished, so the existing glass edge grinding machine usually sets a bracket in the middle position to support the middle position of the glass, so that the glass maintains a stable position and posture, and avoids deviation or tilting during grinding.

DETAILED DESCRIPTION

[0024] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] In the description of the present application, it should be pointed out that the directions or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the indicated devices or elements must have a specific direction, be constructed and operated in a specific direction.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0027] Referring to Figs. 1-2 The present application discloses an automatic adjustment bracket 11, which comprises a workbench 10, a transmission mechanism and a driving mechanism 40. The bracket 11 is arranged along a first direction on the workbench 10 and can move back and forth along a second direction and is used to support a workpiece. The transmission mechanism comprises a first transmission member, which comprises a first driving wheel 21, a first driven wheel 22 and a first conveyor belt 23. The first driving wheel 21 and the first driven wheel 22 are arranged at the side of the workbench 10 in a spaced manner. The first conveyor belt 23 extends along the second direction and is arranged around the first driving wheel 21 and the first driven wheel 22, respectively. The first conveyor belt 23 rotates when the first driving wheel 21 rotates, so as to rotate the first driven wheel 22. The bracket 11 is connected with the first conveyor belt 23 and moves back and forth along the second direction when the first conveyor belt 23 rotates. The driving mechanism 40 is connected with the first driving wheel 21 to drive the first driving wheel 21 to rotate.

[0028] On the basis of the above structure, taking the first direction as the width direction of the workbench 10 and the second direction as the length direction of the workbench 10 as examples, the first driving wheel 21 and the first driven wheel 22 are arranged at the side of the workbench 10 in an interval, and the interval distance between the two is set according to the actual moving distance required by the workpiece. In this way, the first conveying belt 23 is arranged around the first driving wheel 21 and the first driven wheel 22, respectively, and when the first conveying belt 23 moves, the workpiece can be moved within the effective distance.

[0029] Since the workbench 10 needs to be connected with other structures (such as a water tank) during installation, if the first driving wheel 21 and the first driven wheel 22 are connected with the workbench 10 through a support structure or other mounting structure, the volume of the side of the workbench 10 may be increased, which causes the installation space to be limited when the workbench 10 is connected with other structures, and affects the later installation. Therefore, in the embodiment, the first driving wheel 21 and the first driven wheel 22 are directly installed at the side of the workbench, which reduces the setting of the support structure or other mounting structure, indirectly reduces the volume of the workbench 10, and is convenient for later installation.

[0030] In addition, in the embodiment, a driving mechanism 40 is separately arranged and directly connected with the first driving wheel 21 to directly drive the first driving wheel 21 to rotate. Since the first conveying belt 23 is arranged around the first driving wheel 21 and the first driven wheel 22, respectively, when the first driving wheel 21 rotates, the first conveying belt 23 and the first driven wheel 22 rotate synchronously. At this time, the bracket 11 connected with the first conveying belt 23 can move back and forth, which is compared with the setting mode that the bracket 11 is driven to move by the sliding member or other movable member to drive the first conveying belt 23 to move. In the embodiment, the first conveying belt 23 is directly driven to move by the driving mechanism 40, which reduces the intermediate transmission link (such as the sliding member), makes the transmission efficiency higher, and at the same time, reduces the wear of the intermediate transmission link on the first conveying belt 23 and other structures, and indirectly improves the service life of the whole structure.

[0031] It should be noted that the driving mechanism 40 in the embodiment can adopt an existing driving motor, the first driving wheel 21 and the first driven wheel 22 can adopt two meshing transmission gears, and the first conveying belt 23 can adopt a toothed synchronous belt or a chain which meshes with the two gears. Of course, the first driving wheel 21 and the first driven wheel 22 can also select existing rollers, and the first conveying belt 23 can select a flat belt or a plate type conveying belt.

[0032] In addition, the bracket 11 can be directly connected with the first conveying belt 23 by screws or bolts or clamps during assembly, or can be detachably mounted on the first conveying belt 23 by a plate or a support.

[0033] Further, the drive mechanism 40 further comprises a first speed reducer 31, and the driving motor is connected with the power input end of the first speed reducer 31 when assembled, so as to drive the first speed reducer 31 to rotate by the driving motor, and then the power output end of the first speed reducer 31 is connected with the first driving wheel 21, so that the first speed reducer 31 drives the first driving wheel 21 to rotate when rotating, thereby indirectly driving the first conveying belt 23 to move and driving the bracket 11 to move.

[0034] Compared with directly driving the first driving wheel 21 to rotate by the driving motor, the driving motor can be accelerated to wear due to frequent starting, stopping or load change, so that the gear inside the first speed reducer 31 can first bear the impact when the load is too large in the embodiment, thereby avoiding the risk of damaging the driving motor due to directly bearing the too large load, and prolonging the service life of the driving motor.

[0035] As preferred, the first speed reducer 31 in the embodiment can be selected from existing gear reducers, worm reducers or planetary gear reducers.

[0036] In addition, the mounting groove 15 is arranged on the side of the workbench 10, and the mounting groove 15 can be a groove body recessed on the side of the workbench 10. When assembled, the first speed reducer 31 is mounted in the mounting groove 15, so that the first speed reducer 31 is flush with the periphery of the workbench 10 after being mounted, thereby avoiding that the first speed reducer 31 protrudes from the side of the workbench 10 after being mounted, and indirectly reducing the volume of the entire workbench 10, so that the workbench 10 is more convenient to assemble with other structures in the later stage.

[0037] More specifically, since the workpiece (glass) on the workbench 10 needs to be cooled by water spraying during the edge grinding process, the workbench 10 further comprises a cover plate 16. When assembled, one end of the cover plate 16 is connected with the workbench 10 by screws or bolts, and the other end of the cover plate 16 is arranged corresponding to the mounting groove 15 and used to cover the first speed reducer 31. In this way, the first speed reducer 31 is not easy to be loosened after being mounted in the mounting groove 15, the structure is more stable, and the risk of short circuit or internal part damage of the first speed reducer 31 caused by water flow spraying to the first speed reducer 31 when the workbench 10 is running is reduced, thereby indirectly prolonging the service life of the speed reducer.

[0038] It should be noted that the cover plate 16 is further provided with a penetrating interface, and the first driving wheel 21 can be arranged at the penetrating interface, and the power output shaft of the first speed reducer 31 penetrates the penetrating interface and is connected with the first driving wheel 21.

[0039] Further, two first transmission members are arranged on the two sides of the workbench 10, the two ends of the bracket 11 are connected with the two first transmission belts 23 respectively, and two first speed reducers 31 are arranged, and the two first speed reducers 31 are connected with the two first driving wheels 21 respectively, and the driving mechanism 40 is used to drive the two first speed reducers 31 to rotate.

[0040] Specifically, since the bracket 11 extends along the width direction of the workbench 10 and has a certain length, if only one side of the first transmission member drives the bracket 11 to move, the bracket 11 may shake or tilt due to unilateral force. Therefore, in the embodiment, the first transmission member is arranged on the two sides of the workbench 10, and in assembly, the two ends of the bracket 11 are connected with the first transmission belt 23 respectively, and then the two first speed reducers 31 are used to synchronously drive the first driving wheel 21 to rotate, so that the two first transmission belts 23 move synchronously, and the two ends of the bracket 11 are driven to move at the same time, so that the bracket 11 is more stable during movement, which helps to reduce the shaking or tilting of the bracket 11 due to uneven unilateral force.

[0041] In addition, the slide rail 12 and the sliding block 13 are arranged on the two sides of the workbench 10 respectively, in assembly, the slide rail 12 is arranged along the second direction, and the two ends of the bracket 11 are slidably arranged on the slide rail 12 through the sliding block 13. In this way, when the bracket 11 moves back and forth along the second direction under the drive of the first transmission belt 23, the bracket 11 moves more smoothly during movement along the second direction due to the sliding cooperation between the sliding block 13 at the bottom of the bracket 11 and the slide rail 12, so that the bracket 11 is not easy to jam during movement.

[0042] It should be noted that the bottom of the bracket 11 can be connected with the sliding block 13 and the first transmission belt 23 through the connecting piece or the support at the same time, so that the bracket 11 can be connected with the sliding block 13 and the first transmission belt 23 at the same time.

[0043] More specifically, since the sizes and weights of the workpieces (glass) to be supported by the bracket 11 vary during use, if the workpiece is too large or too heavy, a single bracket 11 may not be able to support the large or heavy glass. Therefore, in the embodiment, the bracket 11 is arranged as a plurality of brackets, and in assembly, the two ends of the plurality of brackets 11 are connected with the sliding block 13 and the first transmission belt 23 through the connecting piece (such as a plate or a support) at the same time, so that the plurality of brackets 11 can be driven to move back and forth along the second direction by the first transmission belt 23 and the sliding block 13. In this way, if the size of the workpiece to be supported is too large, the plurality of brackets 11 can be moved to be uniformly distributed under the workpiece by the first transmission belt 23 and the sliding block 13 at the same time, so that the workpiece can be supported by the plurality of brackets 11 at the same time, and the workpiece is more stable during processing and is not easy to fall or tilt.

[0044] As preferred, a connecting bracket 14 is arranged at the bottom of the bracket 11 in the embodiment, the connecting bracket 14 comprises a first plate segment 141 and a second plate segment 142, the second plate segment 142 is vertically connected with the first plate segment 141, in assembly, the first plate segment 141 is connected with the first conveying belt 23, and the second plate segment 142 is connected with the sliding block 13, so that the load is dispersed to the sliding block 13 and the conveying belt through the two plate segments connected vertically with each other, thereby reducing the stress on the single component, helping to enhance the carrying capacity of the bracket 11, so that the bracket 11 can carry heavier workpieces, and the whole support structure is more stable.

[0045] Further, the speed reduction mechanism further comprises a second speed reducer 32 and a third speed reducer 33, in assembly, the power input end of the second speed reducer 32 is connected with the driving mechanism 40, and the first transmission shaft 51 and the second transmission shaft 52 are arranged at the power output end of the second speed reducer 32, the first transmission shaft 51 extends along the second direction and is connected with one of the first speed reducers 31, and the second transmission shaft 52 extends along the first direction and is connected with the power input end of the third speed reducer 33, in this way, when the driving mechanism 40 operates, the second speed reducer 32 is driven to rotate, and then the power is transmitted to one of the first speed reducers 31 and the third speed reducer 33 through the two transmission shafts respectively through the second speed reducer 32, so that the two rotate;

[0046] Meanwhile, the third transmission shaft 53 is further arranged at the power output end of the third speed reducer 33, and the third transmission shaft 53 is coupled with the power input end of the other first speed reducer 31, in this way, when the third speed reducer 33 operates, the power is transmitted to the power input end of the other first speed reducer 31 through the third transmission shaft 53, so as to drive the other first speed reducer 31 to rotate.

[0047] Therefore, in the use of the automatic adjustment bracket 11 in the embodiment, only a single driving mechanism 40 (driving motor) and multiple transmission shafts are needed, the power can be transmitted to multiple speed reducers through multiple transmission shafts, the conversion and loss of energy between multiple motors are reduced, and the overall energy transmission efficiency is improved; in addition, the single driving motor is easy to realize unified control, so that the synchronization and coordination between the speed reducers are better, in this way, the movement of the first conveying belt 23 on both sides of the workbench 10 is also more synchronous, and the movement of the two ends of the bracket 11 is more synchronous.

[0048] Further, the transmission mechanism further comprises two second transmission members, specifically, the second transmission members comprise a second driving wheel 24, a second driven wheel 25 and a second transmission belt 26, two ends of the second transmission belt 26 are respectively arranged on the second driving wheel 24 and the second driven wheel 25, and the second transmission belt 26 rotates when the second driving wheel 24 rotates, so as to drive the second driven wheel to rotate, in assembly, one of the second driving wheels 24 is connected with the first transmission shaft 51 and rotates when the first transmission shaft 51 rotates, and the other second driving wheel 24 is connected with the third transmission shaft 53 and rotates when the third transmission shaft 53 rotates, and the two second driven wheels 25 are respectively connected with the power input ends of the two first speed reducers 31, so that the two second driven wheels 25 rotate, and the two first speed reducers 31 are driven to rotate.

[0049] Specifically, if the first transmission shaft 51 and the third transmission shaft 53 are directly connected with the two first speed reducers 31, the two transmission shafts may be impacted due to the start-stop of the driving motor or the sudden change of the load, and the impact and vibration are directly transmitted to the speed reducer, which may cause the gear and other components in the speed reducer to be worn out and even damaged, therefore, in the embodiment, the two first transmission shafts 51 and the third transmission shaft 53 transmit power to the two second speed reducers 32 through the two second transmission members, the impact and vibration in the transmission process are absorbed and buffered through the cooperation of the second driving wheel 24, the second driven wheel 25 and the second transmission belt 26, the influence of the impact or vibration of the transmission shaft on the first speed reducer 31 due to the start-stop of the driving motor or the sudden change of the load is reduced, so as to enhance the stability of the transmission and indirectly prolong the service life of the whole structure.

[0050] It should be noted that the second driving wheel 24 and the second driven wheel 25 can adopt two meshing gears, and the second transmission belt 26 can adopt a toothed synchronous belt or a chain which meshes with the two gears; of course, the second driving wheel 24 and the second driven wheel 25 can also select existing rollers, and the second transmission belt 26 selects a flat belt or a plate type transmission belt.

[0051] The technical means disclosed in the utility model scheme is not limited to the technical means disclosed in the above-mentioned embodiments, and also includes the technical scheme composed of any combination of the above technical features. It should be noted that, for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements are also considered to be within the protection scope of the utility model.
