Manual turnover is adopted, the production time is long, and the production effect is seriously influenced.

In order to solve this problem, the present embodiment provides a turnover device, as shown in fig. 1-2, the turnover device includes a turnover mechanism 1, a receiving mechanism 2, and a conveying mechanism 3, a manipulator is disposed on one side of the turnover mechanism 1, the manipulator picks and places the workpiece 100 on the turnover mechanism 1, the turnover mechanism 1 is used for carrying and conveying the workpiece 100, and the turnover mechanism 1 is configured to selectively pick and release the workpiece 100, and can turn over the workpiece 100. The receiving mechanism 2 is located below the turnover mechanism 1, and the receiving mechanism 2 is configured to receive and grasp the workpiece 100 released from the turnover mechanism 1. The conveying mechanism 3 is located downstream of the receiving mechanism 2, and the conveying mechanism 3 is configured to receive the workpiece 100 from the receiving mechanism 2 and to be capable of conveying the workpiece 100. Wherein the workpiece 100 is specifically glass, and the glass can be triangular glass, which is glass with high production frequency.

Meanwhile, the labor burden of operators is small, the possibility that both hands of workers contact the surface of the workpiece 100 is reduced, the damage to the workpiece 100 caused by artificial subjective factors is reduced, and the qualified rate of finished products is improved.

Further, as shown in fig. 3 to 4, in order to turn over the workpiece 100, the turning mechanism 1 includes a first rotating roller 11, a second rotating roller 12, a third rotating roller 13 and a turning transmission chain 14, the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 are distributed in a triangular shape, the turning transmission chain 14 is respectively wound around the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 and is in transmission connection therewith, and the turning transmission chain 14 is used for bearing and conveying the workpiece 100. The second rotating roller 12 is positioned above the receiving mechanism 2, and the second rotating roller 12 is configured to drive the workpiece 100 to be turned upside down.

Specifically, the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 are preferably distributed in a right triangle, and the first rotating roller 11 is located at the vertex of the right angle, so that the overturning transmission chain 14 between the second rotating roller 12 and the third rotating roller 13 is a hypotenuse, the other two sides are right-angle sides, and then the included angle of the overturning transmission chain 14 on the two sides of the second rotating roller 12 is an acute angle a.

It is defined that the turning transmission chain 14 is a starting station at the position of the first rotating roller 11, the turning transmission chain 14 is a pre-station at the position of just entering the second rotating roller 12, and the turning transmission chain 14 is a turning station at the position of leaving the second rotating roller 12. The turning transmission chain 14 is driven to move among the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 along with the rotation of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13, in the process, the workpiece 100 moves from the initial station to the pre-station under the conveying action of the turning transmission chain 14, then the workpiece 100 is turned from the pre-station to the turning station by the rotation of the second rotating roller 12, and at the moment, the turning angle of the workpiece 100 is A.

Further, in order to realize the rotation of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13, the turnover mechanism 1 further includes a first driving assembly (not shown in the figure), an output end of the first driving assembly is respectively connected to the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13, and the first driving assembly is configured to drive the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 to rotate.

It is understood that the first driving assembly may include three driving sources, each of which is embodied as a rotating motor, and an output end of each of the driving sources is connected to the first rotating roller 11, the second rotating roller 12, or the third rotating roller 13, and the first driving assembly may further include a driving source and a synchronizer, and the driving sources are respectively connected to the first rotating roller 11, the second rotating roller 12, and the third rotating roller 13 through the synchronizer, so as to realize synchronous rotation of the first rotating roller 11, the second rotating roller 12, and the third rotating roller 13. The present embodiment does not limit the specific driving manner, as long as the rotation of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 can be realized, which is within the protection scope of the present embodiment.

Further, in order to ensure the stability of the workpiece 100 during the moving and turning process, as shown in fig. 5, the turning mechanism 1 further includes a vacuum generator (not shown), suction cups 112 are disposed on the outer walls of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13, and the vacuum generator is communicated with the suction cups 112 for selectively sucking the workpiece 100. Utilize vacuum generator, realize each live-rollers and snatch the effect of work piece 100 for each live-rollers still compromises the dual function of snatching work piece 100 when realizing 14 transmission effects of upset driving chain, has left out other adsorption apparatus and has constructed simple structure, and the design is exquisite, and manufacturing cost is lower.

In order to further increase the stability of grabbing the workpiece 100, as shown in fig. 5, the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 are respectively provided with a main channel 111 along the respective axial direction, the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 are respectively provided with an auxiliary channel along the respective circumferential direction, the main channel 111 is respectively communicated with the vacuum generator and the auxiliary channels, each auxiliary channel is communicated with one suction cup 112, and the auxiliary channels play a role of shunting from the main channel 111.

It is to be understood that the number of the sub-passages is not limited in the present embodiment, and preferably, a plurality of layers of sub-passages are provided at regular intervals along the axial direction of each rotating roller itself, in this way, it is ensured that a plurality of workpieces 100 or workpieces 100 having a large size can be arranged in the axial direction of each rotating roller itself, and the adsorption stability of the workpieces 100 is ensured. Every layer of subchannel is provided with a plurality of subchannels along each live-rollers self circumference direction evenly spaced, adopts this kind of mode, has guaranteed when the live-rollers rotates to each angle, has all played better adsorption to work piece 100.

Since the workpiece 100 passes through the turning station, the turning angle of the workpiece 100 is a, in order to turn the workpiece 100, as shown in fig. 3-4, the receiving mechanism 2 includes a receiving transmission chain 21, a first receiving transmission roller 22 and a second receiving transmission roller 23, the first receiving transmission roller 22 is located at a side close to and below the first rotating roller 11, and the second receiving transmission roller 23 is collinear with the first rotating roller 11 and the second rotating roller 12 in the horizontal direction. The first receiving driving roller 22 and the second receiving driving roller 23 are used for adsorbing the workpiece 100, and the receiving driving chain 21 is wound around the first receiving driving roller 22 and the second receiving driving roller 23 respectively.

Specifically, the receiving transmission chain 21 is defined as a receiving station at a position close to the first receiving transmission roller 22, and after the workpiece 100 passes through the turning station, the vacuum generator stops working, so that the second rotating roller 12 does not draw vacuum on the workpiece 100, and the workpiece 100 freely falls from the turning operation to the receiving station and is conveyed by the receiving transmission chain 21.

Further, as shown in fig. 3 to 4, the reversing transmission chain 14 between the second rotating roller 12 and the third rotating roller 13 is disposed parallel to and opposite to the receiving transmission chain 21, that is, the receiving transmission chain 21 is disposed obliquely with respect to the horizontal plane, and the receiving transmission chain 21 is disposed parallel to the hypotenuse of the right triangle formed by the first rotating roller 11, the second rotating roller 12, and the third rotating roller 13, so that the workpiece 100 is conveyed from the lower end to the upper end of the receiving transmission chain 21 at a predetermined reversing angle a. Since the second driven receiving roller 23 is horizontally collinear with the first rotating roller 11 and the second rotating roller 12, the workpiece 100 is just turned 180 ° relative to the start station when the workpiece 100 is conveyed to the position of the second driven receiving roller 23.

Because the length of the receiving transmission chain 21 is long and the receiving mechanism 2 can sag, the receiving mechanism further comprises a tension roller 24, and the tension roller 24 is positioned between the first receiving transmission roller 22 and the second receiving transmission roller 23, so that the functions of tensioning and transmission are achieved, and the possibility of sagging of the receiving transmission chain 21 is reduced.

It can be understood that the first receiving driving roller 22, the second receiving driving roller 23 and the tension roller 24 can all achieve the rotating and adsorbing effects, and the structures of the first receiving driving roller 22, the second receiving driving roller 23 and the tension roller are similar to those of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13, and the arrangement is different, so the description is omitted.

In order to receive the upper workpiece 100 on the uptake mechanism 2, as shown in fig. 6 to 7, the transport mechanism 3 includes a first transport assembly 31 and a second transport assembly 32, the second transport assembly 32 being located downstream of the first transport assembly 31. The first conveying assembly 31 includes a first driving roller 311, a second driving roller 312, a third driving roller 313 and a first conveying chain 314, the second driving roller 312 is located above the receiving mechanism 2, and the first driving roller 311, the second driving roller 312 and the third driving roller 313 are distributed in a triangular shape and used for adsorbing the workpiece 100. The first conveying transmission chain 314 is respectively wound on the first transmission roller 311, the second transmission roller 312 and the third transmission roller 313 and is in transmission connection with the first transmission roller 311, the second transmission roller 312 and the third transmission roller 313, and the first conveying transmission chain 314 is used for bearing and conveying the workpiece 100. The first conveying assembly 31 is similar to the turnover mechanism 1 in other structures, and therefore, detailed description thereof is omitted.

Meanwhile, as shown in fig. 6 to 7, the second conveying assembly 32 includes a first conveying roller 321, a second conveying roller 322, a third conveying roller 323, a fourth conveying roller 324, and a second conveying transmission chain 325, the first conveying roller 321 and the second conveying roller 322 are located above the third conveying roller 323 and the fourth conveying roller 324, and the first conveying roller 321 and the fourth conveying roller 324 are located at a side close to the first conveying assembly 31. First conveying roller 321, second conveying roller 322, third conveying roller 323 and fourth conveying roller 324 are the rectangular distribution and can adsorb work piece 100, and second conveying drive chain 325 is around locating first conveying roller 321, second conveying roller 322, third conveying roller 323 and fourth conveying roller 324 respectively and is connected with its transmission, and second conveying drive chain 325 is used for bearing and conveying work piece 100.

Specifically, the second conveying transmission chain 325 between the first conveying roller 321 and the second conveying roller 322 is collinear with the first conveying transmission chain 314 between the first conveying roller 311 and the second conveying roller 312, so that the workpiece 100 on the first conveying transmission chain 314 is directly conveyed onto the second conveying transmission chain 325.

It can be understood that the first conveyor roller 321, the second conveyor roller 322, the third conveyor roller 323, and the fourth conveyor roller 324 can perform rotating and adsorbing functions, and are similar to the first rotating roller 11, the second rotating roller 12, and the third rotating roller 13 in structure, but different in arrangement, and therefore will not be described again.

The working process of the turnover device provided by the embodiment is as follows:

grabbing the workpiece 100 onto the turnover mechanism 1 by a manipulator positioned at one side of the turnover mechanism 1;

the overturning transmission chain 14 is driven to move among the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13 along with the rotation of the first rotating roller 11, the second rotating roller 12 and the third rotating roller 13, in the process, the workpiece 100 moves from the initial station to the pre-station under the conveying action of the overturning transmission chain 14, then the workpiece 100 is overturned from the pre-station to the overturning station by the rotation of the second rotating roller 12, and the overturning angle of the workpiece 100 is A;

after the workpiece 100 passes through the turning station, the vacuum generator stops working, so that the second rotating roller 12 does not extract vacuum to the workpiece 100, and the workpiece 100 freely falls to the receiving station from the turning work and is conveyed through the receiving transmission chain 21;

the receiving transmission chain 21 is parallel to the hypotenuse of the right triangle formed by the first rotating roller 11, the second rotating roller 12, and the third rotating roller 13, so that the workpiece 100 is conveyed from the lower end to the upper end of the receiving transmission chain 21 at a predetermined inversion angle a. Since the second driving receiving roller 23 is collinear with the first rotating roller 11 and the second rotating roller 12 in the horizontal direction, when the workpiece 100 is conveyed to the position of the second driving receiving roller 23, the workpiece 100 is just turned 180 degrees relative to the start station;

the first conveying transmission chain 314 is respectively wound on the first transmission roller 311, the second transmission roller 312 and the third transmission roller 313 and is in transmission connection with the first transmission roller 311, the second transmission roller 312 and the third transmission roller 313, and the first conveying transmission chain 314 is used for bearing the workpiece 100 at the upper end of the bearing transmission chain 21 and conveying the workpiece 100;

the second conveying transmission chain 325 between the first conveying roller 321 and the second conveying roller 322 is collinear with the first conveying transmission chain 314 between the first conveying roller 311 and the second conveying roller 312, so that the workpiece 100 on the first conveying transmission chain 314 is directly conveyed to the second conveying transmission chain 325.
