Referring to fig. 9, in some embodiments, the turnover device 50 includes a support frame 51 and an adsorption mechanism 52, the adsorption mechanism 52 is disposed on the support frame 51 in a reciprocating manner along a fourth direction, and the adsorption mechanism 52 has a first adsorption surface for adsorbing or releasing the workpiece.

Referring to fig. 9 and 10, further, the turnover device 50 further includes a first connecting assembly 53 and a material taking member 54, the first connecting assembly 53 is disposed on the support frame 51 in a reciprocating manner along a fifth direction forming an angle with the fourth direction, the material taking member 54 is rotatably connected to the first connecting assembly 53 around a rotation axis perpendicular to the fourth direction, the material taking member 54 has a second adsorption surface for adsorbing or releasing the workpiece, the second adsorption surface can be parallel to the first adsorption surface during the rotation of the material taking member 54, and the material taking member 54 has an alignment position avoiding position during the movement of the first connecting assembly 53 in the fifth direction.

When the extracting member 54 is in the aligned position and the first suction surface is parallel to the second suction surface, the first suction surface may be aligned with the second suction surface in the fourth direction.

When the material taking member 54 is at the avoiding position, the suction mechanism 52 is respectively offset from the first connecting assembly 53 and the material taking member 54 in the fourth direction.

Specifically, the fifth direction is perpendicular to the fourth direction, and the fourth direction is the up-down direction in fig. 10, and the fifth direction is the left-right direction in fig. 10, and when the flipping apparatus 50 is installed on the third station, the fourth direction is a direction perpendicular to the upper side surface of the turntable.

The placing of the flipping device 50 on the third station ensures that the first suction surface can be correspondingly close to or far away from the carrying location 22 of the third station during the movement of the suction mechanism 52 in the fourth direction, i.e. the first suction surface is facing the carrying location 22.

When the second suction surface is parallel to or even aligned with the first suction surface, there are two situations, namely the second suction surface facing the first suction surface and the side of the extractor 54 facing away from the second suction surface facing the first suction surface.

Thus, the material extracting member 54 is moved in the fifth direction to a position sufficiently far from the suction mechanism 52, in which the material extracting member 54 is allowed to rotate circumferentially, which is defined herein as a reversed position. The material taking piece 54 is moved to the overturning position and the material taking piece 54 is rotated to a first angle, at this time, the second adsorption surface of the material taking piece 54 is parallel to the first adsorption surface, and one side of the material taking piece 54, which is far away from the second adsorption surface, faces the first adsorption surface in the fourth direction, and then the material taking piece 54 is moved between the adsorption mechanism 52 and the bearing position 22 located at the third station along the fifth direction and is moved to a position where the second adsorption surface is aligned with the first adsorption surface, so that the second adsorption surface faces a workpiece located at the third station.

The second suction surface sucks the workpiece, then moves to the turning position in the fifth direction, and continues to rotate until reaching a second angle, at which time the second suction surface is again parallel to the first suction surface, and the second suction surface faces the first suction surface, and the workpiece on the second suction surface also rotates with it, and then continues to move the material taking member 54 in the fifth direction until the second suction surface is again aligned with the first suction surface in the fourth direction, and the second suction surface faces the first suction surface, and the workpiece is sucked on the second suction surface, and if at this time the second suction surface is at a certain distance from the first suction surface, the workpiece on the second suction surface can be sucked by moving the suction mechanism 52 in the fourth direction so that the first suction surface approaches the workpiece on the second suction surface, and the workpiece will be sucked, and the second suction surface releases the workpiece.

And finally, the material taking part 54 is moved to the avoiding position along the fifth direction, and the adsorption mechanism 52 moves along the fourth direction to place the workpiece adsorbed by the first adsorption surface back into the bearing position 22 at the third station, so that the workpiece is turned over.

As explained in conjunction with the above-mentioned embodiment, the material taking member 54 is moved to the alignment position when the second suction surface and the first suction surface are parallel, so that the second suction surface sucks the side of the sheet to be processed to which the first sheet is attached, i.e., the first side, and the second side of the sheet to be processed, is exposed, and then the take off member 54 is turned 180 degrees in the flipped position, and the material taking part 54 is moved to the aligned position again, and then the distance between the first adsorption surface and the second adsorption surface is adjusted by moving the adsorption mechanism 52 along the fourth direction, so that the first adsorption surface is close to the sheet to be processed on which the first patch is stuck, then the first adsorption surface adsorbs the second side of the to-be-processed sheet, the second adsorption surface releases the to-be-processed sheet and moves to the avoiding position, the adsorption mechanism 52 moves along the fourth direction again to place the to-be-processed sheet back to the bearing position 22, the to-be-processed sheet placed back to the bearing position 22 is turned over, and the second side of the to-be-processed sheet is exposed.

Meanwhile, the material taking part 54 cannot move along the fourth direction, and the material taking part 54 needs to adsorb the workpiece on the bearing position 22, so that when the material taking part 54 rotates to the side where the second adsorption surface is parallel to the first adsorption surface but the material taking part 54 deviates from the second adsorption surface and faces the first adsorption surface, the interval between the second adsorption surface and the bearing position 22 in the fourth direction is small, and the second adsorption surface can adsorb the workpiece when moving above the workpiece. The bearing position 22 is a position on the upper side surface of the turntable, the second adsorption surface has a smaller interval with the bearing position 22, that is, the interval between the second adsorption surface and the upper side surface of the turntable is smaller, and the material taking member 54 cannot rotate circumferentially when approaching the turntable. The picking member 54 can only be moved to the inverting position first to ensure that the picking member 54 is inverted.

Referring to fig. 9 and 10, in some embodiments, the adsorbing mechanism 52 includes a first connecting element 522 and an adsorbing element 524, the first connecting element 522 is disposed on the supporting frame 51 in a reciprocating manner along the fourth direction, the adsorbing element 524 is connected to the first connecting element 522, the adsorbing element 524 has a first adsorbing surface, and the first adsorbing surface is located on a side of the adsorbing element 524 away from the first connecting element 522.

Further, the turnover device 50 further includes a first telescopic driving member 55, the first telescopic driving member 55 is disposed on the supporting frame 51, and a telescopic end of the first telescopic driving member 55 is connected to one side of the adsorbing member 524, which is connected to the first connecting member 522, for driving the adsorbing member 524 to move along the fourth direction. Of course, in other embodiments, the telescopic end of the first telescopic driving member 55 may be directly connected to the first connecting member 522 to indirectly drive the suction member 524 to move in the fourth direction.

In practical applications, the supporting frame 51 has a processing space, the adsorbing member 524 is disposed in the processing space, the first connecting member 522 includes at least two first guide rods, one end of each of the at least two first guide rods is connected to one side of the adsorbing member 524, the other end of each of the at least two first guide rods extends in a fourth direction and penetrates out of the top of the supporting frame 51, and the first telescopic driving member 55 is disposed at the top of the supporting frame 51.

Specifically, first flexible driving piece 55 is the cylinder, and the quantity of first guide bar is four, and divide into two sets ofly, and the one end that support frame 51 was worn out to two first guide bars of the same group is passed through the connecting rod and is connected, and the connecting rod can't pass support frame 51 top to when making first guide bar lead the removal of adsorbing piece 524 along the fourth direction, the connecting rod can also carry on spacingly to the removal of adsorbing piece 524.

Of course, in some embodiments, the suction member 524 may be directly and solely driven to move along the fourth direction by the first telescopic driving member 55 connected to the suction member 524, and the first connecting member 522 is not provided, but there is a lack of guidance, so that the positions of the workpiece before and after being turned may be deviated, and therefore, the first connecting member 522 is preferably provided to move the suction member 524 along the fourth direction.

In some embodiments, the supporting frame 51 is provided with a guide portion extending along the fifth direction, and the first connecting assembly 53 includes a second connecting member 532, a first connecting plate 534 and a second guide bar 536. The second connecting member 532 is reciprocally disposed at the guiding portion along a fifth direction, one side of the first connecting plate 534 is fixedly connected to the second connecting member 532, one end of the second guiding rod 536 is connected to one side of the first connecting plate 534 away from the second connecting member 532, the second guiding rod 536 extends along the fourth direction towards a direction away from the first connecting plate 534, and the material taking member 54 is connected to the second guiding rod 536 to move along the fifth direction along with the second guiding rod 536.

It is understood that the engagement between the second connector 532 and the guide is similar to a rail engagement and the specific embodiment is not limited.

Further, the first connecting assembly 53 further includes a connecting block, the connecting block is connected to one side of the first connecting plate 534, which is connected to the second connecting member 532, the turnover device 50 further includes a second telescopic driving member 56 disposed on the supporting frame 51, the connecting block is connected to one side of the first connecting plate 534, and a telescopic end of the second telescopic driving member 56 is connected to the connecting block for driving the connecting block to move along the fifth direction, so as to drive the first connecting plate 534 to move on the guide portion along the fifth direction.

In some embodiments, the flipping apparatus 50 further comprises a second connecting assembly 57, the second connecting assembly 57 is reciprocally movably disposed in the fourth direction at the first connecting assembly 53, and the material taking member 54 is rotatably connected to the second connecting assembly 57 about the rotation axis. Further, the second connecting assembly 57 is reciprocally disposed on the second guide bar 536 along the fourth direction, and the material-taking member 54 is connected to the second connecting assembly 57.

It should be noted that, in the case that the second connecting assembly 57 is provided, the material taking member 54 can be moved in the fifth direction and the fourth direction to be away from the turntable, so that the material taking member 54 can rotate unimpededly, and the workpiece can be turned over by 180 degrees. Moreover, if the second connecting component 57 is provided, the suction mechanism 52 can be operated only by placing the reversed workpiece back on the carrying position 22, so that the suction mechanism 52 can be set to move back and forth between two positions, one is a position far away from the carrying position 22, and the other is a position close to the carrying position 22 to place the workpiece on the first suction surface on the carrying position 22, which can simplify the control procedure and facilitate the operation. The corresponding material taking member 54 needs to be turned over and moved to two positions corresponding to the suction mechanism 52 and the carrying position 22, so as to suck the workpiece at the carrying position 22 and turn over the workpiece, and then move the turned-over workpiece to the suction mechanism 52.

Meanwhile, when the material taking member 54 is movable in the fourth direction and the adsorbing mechanism 52 moves away from the bearing position 22 to the maximum distance from the bearing position 22, if the distance between the adsorbing mechanism 52 and the bearing position 22 is large enough to enable the material taking member 54 to rotate circumferentially between the adsorbing mechanism and the bearing position 22 at the time, the material taking member 54 can also move directly in the fourth direction and then turn over after adsorbing the workpiece, and does not need to be away from the adsorbing mechanism 52 and the turntable in the fifth direction.

The space for securing the rotation of the pickup member 54 is to avoid interference with the rotation of the pickup member 54 by other structures, and is to avoid interference with the movement of the adsorption mechanism 52 in the fourth direction when the pickup member 54 is located at the retracted position. The movement of the material taking member 54 is actually realized by the first connecting component 53 or the first connecting component 53 and the second connecting component 57, that is, when the material taking member 54 is located at the avoiding position, the first connecting component 53 and even the second connecting component 57 do not interfere with the movement of the adsorption mechanism 52 in the fourth direction.

By providing the second connecting member 57 to effect movement of the picking member 54 in the fourth direction, when the workpiece is turned over and the second suction surface is moved to a position aligned with the first suction surface in the fourth direction, if there is a space between the first suction surface and the second suction surface in the fourth direction at this time, it is possible to effect that the workpiece adsorbed on the second suction surface approaches the first suction surface by moving the picking member 54 in the fourth direction, i.e., the adsorption mechanism 52 described above may be moved only between the two positions.

Of course, in another embodiment, when the first suction surface and the second suction surface are aligned in the fourth direction after the material taking member 54 is turned over, if there is a gap between the first suction surface and the second suction surface in the fourth direction, the first suction surface can be close to the workpiece adsorbed on the second suction surface by moving the adsorption mechanism 52 in the fourth direction, without moving the material taking member 54 continuously, and after the adsorption mechanism 52 adsorbs the workpiece, the material taking machine 54 can be moved to the avoiding position, and the adsorption mechanism 52 directly moves down to the carrying site 22 to release the workpiece.

In some embodiments, the second connecting assembly 57 includes a second connecting plate 572 and a third connecting plate 574, the second connecting plate 572 is reciprocally disposed on the first connecting assembly 53 along the fourth direction, the third connecting plate 574 is disposed at an angle with the second connecting plate 572, and the material taking member 54 is rotatably disposed on one side of the third connecting plate 574 about the rotation axis.

Further, the second connecting assembly 57 further includes a linear bearing, the linear bearing is disposed through the second connecting plate 572 in the fourth direction, and the second guide rod 536 is disposed through the linear bearing in the fourth direction, so that the second connecting plate 572 is disposed on the second guide rod 536 in a manner of being capable of reciprocating in the fourth direction.

Specifically, the number of the second guide bars 536 is four, and the number of the corresponding linear bearings is four, so as to ensure that the second connecting plate 572 accurately moves in the fourth direction, and thus ensure that the material taking member 54 accurately moves in the fourth direction.

In some embodiments, the flipping apparatus 50 further comprises a third telescopic driving member 58, the third telescopic driving member 58 is disposed at one side of the first connecting plate 534 connected to the second guiding bar 536, and a telescopic end of the third telescopic driving member 58 is connected to the second connecting plate 572 for driving the second connecting plate 572 to move in the fourth direction.

In practice, the second connecting member 57 is similar to a rod suspended from one side of the first connecting plate 534, and the second guide bar 536 guides the movement of the second connecting member 57.

In some embodiments, the second connecting plate 572 has a U-shaped notch, and the third connecting plate 574 is connected to the second connecting plate 572 at an angle with respect to the U-shaped notch, that is, the third connecting plate 574 is a U-shaped plate, and the material taking member 54 is rotatably connected to the third connecting plate 574 and located in the U-shaped notch or the middle of the U-shaped plate.

In some embodiments, the turnover device 50 further includes a turnover mechanism, the turnover mechanism includes a rotary driving member 591, a driving wheel 592, a synchronous belt 593 and a synchronous pulley 594, the rotary driving member 591, the driving wheel 592 and the synchronous pulley 594 are disposed on the second connection assembly 57, the synchronous belt 593 is drivingly connected between the rotary driving member 591 and the synchronous pulley 594 to drive the synchronous pulley 594 to rotate around the rotation axis, and the material taking member 54 is connected to the synchronous pulley 594.

In practical application, tilting mechanism still includes take-up pulley 595, but take-up pulley 595 reciprocating sets up in third connecting plate 574, and is located between synchronous pulley 594 and the action wheel 592, and hold-in range 593 is around locating take-up pulley 595, and the removal of take-up pulley 595 can be adjusted hold-in range 593's tension to prevent hold-in range 593 and skid.

Specifically, the rotary drive member 591 is a servo motor.

The material taking part 54 is directly connected to the synchronous pulley 594, and the rotation angle of the synchronous pulley 594 is the rotation angle of the material taking part 54, so that the controller can control the rotation angle of the material taking part 54 according to the driven rotation angle of the synchronous pulley 594 to realize the overturning of the workpiece.

Further, the radial dimension of action wheel 592 is the same with synchronous pulley 594's radial dimension, and tilting mechanism still includes second detection mechanism and regulator, and second detection mechanism and regulator all are connected with the controller electricity, and second detection mechanism is used for detecting the initiative turned angle of action wheel 592, and the regulator is used for controlling take-up pulley 595's removal, and the controller moves according to initiative turned angle and synchronous turned angle control regulator to tighten hold-in range 593.

Since the radial dimension of the driving pulley 592 is the same as the radial dimension of the timing pulley 594, in the case of stable transmission of the timing belt 593, i.e., in the case of no slip of the timing belt 593, the driving rotation angle and the timing rotation angle are the same, and if the angles measured by the two detection mechanisms are different, it indicates that the timing belt 593 slips, and the controller controls the adjuster to adjust the tension roller so as to tension the timing belt 593.

It should be explained that the synchronous pulley 594 and the driven pulley are rotatably disposed on the third connecting plate 574 through a rotating shaft and a bearing, which are conventional in implementation and are not described herein.

In addition, the radial dimension of the driving pulley 592 and the radial dimension of the timing pulley 594 may be different, but a difference between the driving rotation angle and the synchronous rotation angle, i.e., an operational relationship between the driving rotation angle and the synchronous rotation angle under a normal condition, needs to be determined, and the controller determines whether the driving rotation angle and the synchronous rotation angle are consistent with a preset operational relationship after acquiring the driving rotation angle and the synchronous rotation angle, if so, the controller indicates that the synchronous belt 593 is in a normal operation state, and if not, the controller determines that the synchronous belt 593 has a slip state.
