Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a glass lifting and rotating table. Background Art

[0002] Flat glass is widely used in various fields of social life, including building construction and various production and living utensils. With the rapid development of Industry 4.0 technology and the increasing maturity of software technology, in the glass processing industry, automated glass processing plants are increasingly popular due to their fast and efficient production efficiency and the fact that no personnel are required at dangerous workstations. In an automated glass processing plant, due to the requirements of automatic sheet sorting, automatic layout technology, and automatic conveying and edging, during the process of conveying the cut glass to the next process on the production line, rotation operations are required, that is, the long and short sides of the cut glass need to be reasonably rotated and adjusted according to the actual requirements of the production line in the conveying direction, which becomes an essential task.

[0003] First of all, in order to improve the strength of the glass and ensure its safety during actual use, the physical tempering method is usually used to temper the cut glass after edging and cleaning. The specific principle is as follows: the glass is put into a tempering furnace, heated to an appropriate temperature, and then quickly cooled, causing the surface of the glass to shrink rapidly, generating compressive stress, while the middle layer of the glass cools more slowly and has not had time to shrink, so tensile stress is formed, thereby enabling the glass to obtain higher strength.

[0004] To maximize the use efficiency of the tempering furnace, as many glass sheets as possible need to be put in for each tempering operation. Therefore, the glass sheets need to be sorted and arranged before being put into the tempering furnace. In the prior art, there are transfer devices for transporting glass sheets, but such devices generally have the following problems: the glass sheets need to be adjusted in direction in a timely manner during the equipment transportation process so that each glass sheet can be aligned. However, currently, most of the direction adjustment operations of the glass sheets are completed through manual operation or manual-assisted operation. Such an operation method will, on the one hand, consume a large amount of labor costs and have low processing efficiency. At the same time, the manual operation method is prone to inaccurate or imprecise glass sheet commutation, resulting in a high error rate of glass sheet commutation and affecting subsequent tempering operations.

[0005] Secondly, in the current automated production line, the feeding and discharging of the edging operation are both automatically completed. In order to reasonably arrange the production line rhythm, it is necessary to consider whether to grind the long side of the glass first or the short side first. At this time, it involves the problem of rotating the glass sheets exported from the sheet sorting cage.

[0006] In summary, with the increasing popularization and application of glass automated processing plants, there will be more and more requirements for the rotating operation of glass during transportation. Therefore, there is a need in the market for a glass lifting and rotating device that is easy to use, efficient, reasonable in layout, and high in cost performance to meet this demand.

[0007] In the existing technology, there are already various glass lifting and rotating tables on the market that can meet the glass rotating operation. Most of them are composed of a device main body, a tray, and a direction adjustment mechanism. Among them, the device main body includes a frame and a glass conveying mechanism, and the conveying mechanism is arranged on the top of the frame; in the tray and the direction adjustment mechanism, the tray is fixedly arranged on the top of the direction adjustment mechanism, and the direction adjustment mechanism is fixedly arranged on the frame. Among them, the direction adjustment mechanism is used to control the lifting movement and the rotating movement of the tray.

[0008] These glass lifting and rotating tables can realize the lifting movement and the rotating movement of the glass sheets placed on the tray by setting a direction adjustment mechanism that can be lifted and rotated. Through the continuous rotation of the direction adjustment mechanism and the continuous conveying operation of the conveying mechanism, it is ensured that the commutation adjustment operation between multiple groups of glass sheets can be carried out continuously without interruption, and the commutation operation efficiency of the glass sheets is relatively high.

[0009] The above-mentioned existing technical solutions have the following defects: Looking at the structures of these glass lifting and rotating tables on the market, it can be found that their device main bodies, including the frame and the glass conveying mechanism, are similar, and they all realize the horizontal conveying of glass in the way of a roller mechanism. The difference lies in the transmission method of the roller shaft. Some use a chain transmission method, and some use a bevel gear transmission method.

[0010] In terms of the lifting method of the rotating table, most of them use a cylinder to lift the overall direction adjustment mechanism to realize the glass lifting operation; a small number use a motor to drive a rack and pinion structure or a synchronous belt structure to realize the glass lifting operation; and there are also individual ones that use a cam and a link mechanism to realize the glass lifting operation.

[0011] In terms of the rotating method of the rotating table, at present, most of them on the market drive the driving small gear through a servo motor and a planetary gear reducer, and then drive a large internal gear or external gear through the driving small gear to realize the rotation of the direction adjustment mechanism. Due to the relationship of the size of the glass to be conveyed, after adding the weight of the entire glass rotating table and the glass to be rotated, the rotating weight is large and the inertia is large, resulting in that the corresponding gear mechanism plus the servo motor, the planetary gear reducer, and the paired gear mechanism must all meet these usage conditions, thus making the overall cost of the rotating system relatively high; during the rotating movement, due to the reason of the fitting clearance, the positioning accuracy is not high, and during the continuous rotating operation, the repeated accuracy is poor, and it is often necessary to correct the starting point of the rotating movement through the positioning origin. Otherwise, the cumulative error after continuous rotation will cause the rotating mechanism to be unable to accurately position. Utility Model Content

[0012] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a glass lifting and rotating table, which has a simple structure, ensures the positioning accuracy of the glass after rotation, and can prevent the glass from being displaced during the rotation of the rotating table, resulting in the rotation positioning accuracy failing to meet the use requirements.

[0013] The above utility model object of the utility model is achieved through the following technical solutions:

[0014] A glass lifting and rotating platform comprises a lifting and rotating mechanism and a glass lifting and rotating bracket, wherein the glass lifting and rotating bracket is detachably and fixedly connected to the lifting and rotating mechanism;

[0015] The lifting and rotating mechanism is used to drive the glass lifting and rotating bracket to lift and rotate on the glass lifting and rotating conveying platform. The glass lifting and rotating bracket is used to carry glass, and the glass lifting and rotating bracket is placed on the glass lifting and rotating conveying platform.

[0016] As a further technical solution of the utility model: the lifting and rotating mechanism includes a box body and a lifting mechanism and a rotating mechanism installed in the box body, the lifting mechanism is transmission connected to the rotating mechanism, the lifting mechanism is used to drive the rotating mechanism to move up and down in the box body, and the rotating shaft of the rotating mechanism is detachably fixedly connected to the glass lifting and rotating bracket.

[0018] As a further technical solution of the utility model: a slide rail is installed on the side wall inside the box body, a connecting plate is fixed to one side of the bottom of the mounting base plate, a plurality of sliding blocks are fixed to a side of the connecting plate away from the cylinder, and the sliding blocks are slidably arranged on the slide rail.

[0019] As a further technical solution of the utility model: the rotating mechanism is a cam divider or a hollow rotating platform.

[0020] As a further technical solution of the utility model: the cam divider includes a base, a rotating shaft, an input shaft, a reducer and a motor, the motor is transmission-connected to the input shaft through the reducer, the input shaft is transmission-connected to the rotating shaft, and the rotating shaft is rotatably arranged on the base.

[0021] As a further technical solution of the present utility model: a position indicator is installed on the outer side of the base close to the input shaft.

[0022] As a further technical solution of the present utility model: the glass lifting and rotating bracket includes a bracket main body and a fixing plate fixed at the center of the bracket main body. A groove for embedding the rotating shaft is formed on the fixing plate. A plurality of mounting holes are formed at the bottom of the groove.

[0024] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0025] 1. The present utility model discloses a glass lifting and rotating table, which uses a cam divider as the rotating mechanism of the glass lifting and rotating bracket and a cylinder as the lifting mechanism of the glass lifting and rotating bracket, very well meeting the requirements of glass lifting and rotating operations. It realizes the rotation mode of the direction adjustment mechanism in a simple and easy way by replacing the method in the market where a servo motor and a planetary gear reducer drive a driving pinion, and then the driving pinion drives a large internal gear or external gear. This not only significantly reduces the cost of hardware, but also makes the software control simple and easy. As a result, the manufacturing cost of the entire glass rotating table assembly is significantly reduced, and the reliability is significantly increased.

[0026] 2. In the cam divider, by adjusting the eccentric bearing seat of the rotating support input shaft, the preload between the cam on the input shaft and the cam roller on the output shaft is changed to make it close to the elastic zone of the cam, thereby strengthening the contact stiffness between the two contacting elements of the cam on the input shaft and the cam roller on the output shaft, increasing the contact rigidity, completely eliminating the meshing clearance and the phenomenon of non-smooth rotation, and making the positioning accuracy of the entire rotating mechanism high.

[0027] 3. In the cam divider, the precisely designed cam always rotates in a cycle relying on its own processed curved surface. Each cycle drives the output shaft to rotate according to a specific cam contour curve, making it easy for the output shaft to achieve a specific acceleration rotation curve. Therefore, when the glass lifting bracket drives the glass to rotate, it is easy to achieve smooth acceleration and smooth deceleration, ensuring that the glass on it is affected by the inertial force to the minimum during the rotation movement and is not prone to sliding and displacement phenomena.

[0028] 4. In a cam divider, the precisely designed cam has been relying on its own machined surface to perform cyclic rotation. In each cycle, it drives the output shaft to perform rotational motion according to a specific cam contour curve, and does not require frequent origin repositioning like other mechanisms to correct the starting point of the rotational motion.

The glass lifting and rotating bracket 2 is detachably fixed to the cam divider 13, so that the glass lifting and rotating bracket 2 can be lifted and separated from the glass lifting and rotating conveyor table 3, facilitating the cam divider 13 to drive the glass lifting and rotating bracket 2 to rotate and adjust the position.

[0042] A slide rail 124 is installed on the side wall inside the box body 11. One side of the bottom of the mounting base plate 123 is fixed with a connecting plate 125. A plurality of sliders 126 are fixed to the side of the connecting plate 125 away from the cylinder 122. The sliders 126 are slidably arranged on the slide rail 124.

This not only significantly reduces the hardware cost but also makes the software control simple and feasible. As a result, the manufacturing cost of the entire glass rotating table assembly is significantly reduced and the reliability is significantly increased.

[0046] Embodiment Two:

[0047] The present utility model also discloses a glass lifting and rotating table, which is different from Embodiment One in that the rotating mechanism is a hollow rotating platform. In this embodiment, the hollow rotating platform is a prior art in the technical field, and the internal structure is not described in detail.

[0048] The main function of the hollow rotating platform is to replace the imported DD motor due to requirements of space structure, torque, transmission accuracy, and price cost. The hollow rotating platform not only has high precision (the repeat positioning accuracy reaches 0.00027 degrees), but also adopts large-thrust tapered roller bearings of FAG inside the turntable, which can bear heavier axial loads. At present, the product demand for hollow rotating platforms in the field of intelligent equipment manufacturing in China is in short supply.

[0049] In this embodiment, the hollow rotating platform applies German gear processing technology and introduces the design theory of German slender teeth, making the meshing degree of the gear set reach about 2.23 during transmission.
