It should be noted that, the connecting post 263 is disposed through the mounting hole, but the cantilever 264 is connected to one end of the connecting post 263, so when the spring pushes the connecting post 263 to move downward, the pressing end moves from the avoidance position to the pressing position along the preset track, if no piece to be processed is present on the carrying position, the cantilever 264 may abut against the connecting portion 261, the connecting post 263 stops moving, and if a piece to be processed is present on the carrying position, the pressing end may abut against the piece to be processed, and the connecting post 263 also stops moving.

It should be further noted that, in conjunction with fig. 5, the movement of the connecting post 263 may be limited by the spiral groove 2622, so that the movement stroke of the connecting post 263 is determined, that is, the connecting post 263 moves up and down within a certain range, and when there is no piece to be processed in the carrying position, the cantilever 264 may abut against the connecting portion 261, or the connecting post 263 may stop moving down before the cantilever 264 contacts with the connecting portion 261, so that the cantilever 264 does not contact with the connecting portion 261.

In some embodiments, the positioning apparatus 20 further includes a spacer disposed on a side of the connection portion 261 facing away from the cam portion 262 for abutting the cantilever 264 when the cantilever 264 moves downward.

Meanwhile, one end of the tape assembly 484, which outputs the tape, can be close to or far from the to-be-processed sheet and the first patch at the carrying position 22, and the tape assembly 484 is of an existing structure, so that the description thereof will be omitted.

Referring to fig. 9, in some embodiments, the turning apparatus 50 includes a support frame 51 and an adsorption mechanism 52, the adsorption mechanism 52 is reciprocally disposed on the support frame 51 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 turning apparatus 50 further includes a first connecting component 53 and a material taking component 54, where the first connecting component 53 is reciprocally disposed on the supporting frame 51 along a fifth direction that is angled with respect to the fourth direction, the material taking component 54 is rotatably connected to the first connecting component 53 about a rotation axis perpendicular to the fourth direction, the material taking component 54 has a second adsorption surface for adsorbing or releasing a workpiece, the second adsorption surface can be parallel to the first adsorption surface during rotation of the material taking component 54, and the material taking component 54 has an alignment position avoiding position during movement along with the first connecting component 53 in the fifth direction.

When the take-out 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 a fourth direction.

When the material taking member 54 is at the avoiding position, the adsorption mechanism 52 is staggered with respect to 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, the fifth direction is the left-right direction in fig. 10, and the fourth direction is the direction perpendicular to the upper side surface of the turntable when the flipping apparatus 50 is mounted on the third station.

When the turning device 50 is placed on the third station, it is ensured that the first suction surface can be correspondingly close to or far from the bearing position 22 of the third station during the movement of the suction mechanism 52 along the fourth direction, i.e. the first suction surface is facing the bearing position 22.

When the second suction surface is parallel or even aligned with the first suction surface, there are two situations in which the second suction surface faces the first suction surface and the side of the take-out member 54 facing away from the second suction surface faces the first suction surface.

Thus, the take-off member 54 has a position sufficiently far from the suction mechanism 52 to allow circumferential rotation of the take-off member 54, defined herein as a flipped position, when moving in the fifth direction. The material taking part 54 is moved to the overturning position and the material taking part 54 is rotated to a first angle, at this time, the second adsorption surface of the material taking part 54 is parallel to the first adsorption surface, one side of the material taking part 54 away from the second adsorption surface faces the first adsorption surface in the fourth direction, and then the material taking part 54 is moved to a position between the adsorption mechanism 52 and the bearing position 22 located at the third station along the fifth direction and to a position where the second adsorption surface is aligned with the first adsorption surface, so that the second adsorption surface faces the workpiece located at the third station.

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

Finally, the material taking part 54 is moved to the avoiding position along the fifth direction, and the adsorbing mechanism 52 is moved along the fourth direction to replace the workpiece adsorbed by the first adsorbing surface in the bearing position 22 positioned at the third station, so that the workpiece is turned over.

As explained in connection with the above embodiment, the material taking member 54 is moved to the aligned 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 patch is attached, i.e., the first side, the second side of the sheet to be processed is exposed, then the material taking member 54 is turned 180 degrees in the turning position, and the material taking member 54 is moved to the aligned position again, then the distance between the first suction surface and the second suction surface is adjusted by the movement of the suction mechanism 52 in the fourth direction so that the first suction surface approaches the sheet to be processed to which the first patch is attached, then the first suction surface sucks the second side of the sheet to be processed, the second suction surface releases the sheet to be processed and moves to the avoidance position, the suction mechanism 52 is moved again in the fourth direction to put the sheet to be processed back to the carrying position 22, the sheet to be processed in the carrying position 22 has been turned, and the second side of the sheet to be processed is exposed.

Meanwhile, the material taking part 54 cannot move along the fourth direction, and the material taking part 54 needs to absorb the workpiece located on the carrying position 22, so that it needs to be ensured that when the material taking part 54 rotates to the position that the second absorption surface is parallel to the first absorption surface, but one side of the material taking part 54 away from the second absorption surface faces the first absorption surface, the interval between the second absorption surface and the carrying position 22 in the fourth direction is smaller, so that the second absorption surface can absorb the workpiece when moving above the workpiece. The carrying position 22 is a position on the upper surface of the turntable, and the second adsorption surface is spaced from the carrying position 22 by a smaller distance, that is, a smaller distance from the upper surface of the turntable, so that the material taking member 54 cannot rotate circumferentially when approaching the turntable. The take-off 54 can only be moved to the inverted position first to ensure that the take-off 54 is inverted.

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

Further, the flipping apparatus 50 further includes a first telescopic driving member 55, where 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 a side of the adsorbing member 524 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 telescoping end of the first telescoping drive member 55 can be directly connected to the first link member 522 to indirectly drive the suction member 524 in the fourth direction.

In practical application, the support frame 51 has a processing space, the absorbing member 524 is disposed in the processing space, the first connecting member 522 includes at least two first guiding rods, one end of each of the at least two first guiding rods is connected to one side of the absorbing member 524, the other end extends along the fourth direction and extends out from the top of the support frame 51, and the first telescopic driving member 55 is disposed at the top of the support frame 51.

Specifically, the first telescopic driving pieces 55 are cylinders, the number of the first guide rods is four, the first guide rods are divided into two groups, one ends of the two first guide rods in the same group penetrating out of the supporting frame 51 are connected through the connecting rods, and the connecting rods cannot penetrate through the top of the supporting frame 51, so that the first guide rods can guide the movement of the adsorbing piece 524 along the fourth direction, and meanwhile, the connecting rods can limit the movement of the adsorbing piece 524.

Of course, in some embodiments, the suction member 524 may be directly connected to the suction member 524 by the first telescopic driving member 55 alone to drive the suction member 524 to move along the fourth direction, and the first connecting member 522 is not provided, but the guiding is omitted, so that the position of the workpiece before and after being turned may deviate, and therefore, the suction member 524 is preferably moved along the fourth direction by providing the first connecting member 522.

In some embodiments, the support bracket 51 is provided with a guide portion extending in the fifth direction, and the first connection assembly 53 includes a second connection piece 532, a first connection plate 534, and a second guide bar 536. The second connecting member 532 is reciprocally disposed on the guide portion along the 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 in a direction away from the first connecting plate 534, and the material taking member 54 is connected to the second guiding rod 536 so as to move along the fifth direction along with the second guiding rod 536.

It will be appreciated that the engagement between the second connector 532 and the guide is similar to a rail engagement, and the embodiment is not limited.

Further, the first connecting assembly 53 further includes a connecting block connected to the first connecting plate 534 at a side connected to the second connecting member 532, and the turning device 50 further includes a second telescopic driving member 56 disposed on the support frame 51, the connecting block is connected to the first connecting plate 534 at a side, 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, thereby driving the first connecting plate 534 to move along the fifth direction on the guide portion.

In some embodiments, the flipping apparatus 50 further comprises a second connecting assembly 57, the second connecting assembly 57 being reciprocally disposed on the first connecting assembly 53 along a fourth direction, and the take-out member 54 being rotatably connected to the second connecting assembly 57 about an axis of rotation. Further, the second connecting member 57 is reciprocally disposed within the second guide bar 536 along the fourth direction, and the take-out member 54 is coupled to the second connecting member 57.

In the case where the second connecting assembly 57 is provided, the material taking member 54 may be moved away from the turntable in the fifth direction and the fourth direction, so that the material taking member 54 may be turned over 180 degrees without being blocked. In addition, if the second connecting component 57 is provided, the adsorbing mechanism 52 can only put the turned workpiece back onto the bearing position 22, so that the adsorbing mechanism 52 can be set to move back and forth between two positions, one is far away from the bearing position 22, and the other is near to the bearing position 22 to put the workpiece on the first adsorbing surface at the position of the bearing position 22, thereby simplifying the control procedure and facilitating 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 of 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 carrying position 22 to the maximum distance from the carrying position 22, if the distance between the adsorbing mechanism 52 and the carrying position 22 is sufficiently large so that the material taking member 54 can perform circumferential rotation between the adsorbing mechanism and the carrying position 22, the material taking member 54 can also move in the fourth direction and then turn over after adsorbing the workpiece, without also moving away from the adsorbing mechanism 52 and the turntable in the fifth direction.

In addition, the space for ensuring the rotation of the material taking member 54 is to avoid interference between other structures and the rotation of the material taking member 54, so as to avoid interference to the movement of the adsorption mechanism 52 along the fourth direction when the corresponding material taking member 54 is located at the avoiding position. The movement of the material taking member 54 is actually achieved by the first connecting assembly 53 or the first connecting assembly 53 and the second connecting assembly 57, that is, when the material taking member 54 is located at the avoiding position, the first connecting assembly 53 and even the second connecting assembly 57 do not interfere with the movement of the adsorption mechanism 52 along the fourth direction.

The movement of the take-out member 54 in the fourth direction is achieved by providing the second connecting member 57, and 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, the workpiece sucked on the second suction surface can be brought closer to the first suction surface by moving the take-out member 54 in the fourth direction, i.e., the suction mechanism 52 described above can be moved only between the two positions.

Of course, in another embodiment, when the first adsorption surface and the second adsorption surface are aligned in the fourth direction after the material taking member 54 is turned over, if there is a space between the first adsorption surface and the second adsorption surface in the fourth direction at this time, the first adsorption surface can be close to the workpiece adsorbed on the second adsorption surface by moving the adsorption mechanism 52 in the fourth direction, without continuing to move the material taking member 54, and the material taking machine 54 can be moved to the avoiding position after the adsorption mechanism 52 adsorbs the workpiece, the adsorption mechanism 52 is directly moved down to the carrying position 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 respect to the second connecting plate 572, and the take-out member 54 is rotatably disposed on one side of the third connecting plate 574 about the rotation axis.

Further, the second link assembly 57 further includes a linear bearing penetrating the second link plate 572 in the fourth direction, and the second guide bar 536 penetrating the linear bearing in the fourth direction, thereby realizing the reciprocal movement of the second link plate 572 in the fourth direction on the second guide bar 536.

Specifically, the number of second guide bars 536 is four, corresponding to the number of linear bearings, to ensure that the second connecting plate 572 accurately moves in the fourth direction, and thus, the take-out 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 being disposed on a 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 being connected to the second connecting plate 572 for driving the movement of the second connecting plate 572 in the fourth direction.

In practice, the second link assembly 57 is similar to being suspended from one side of the first link plate 534, and the second guide bar 536 guides the movement of the second link assembly 57.

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

In some embodiments, the flipping apparatus 50 further comprises a flipping mechanism including a rotation driving member 591, a driving wheel 592, a timing belt 593, and a timing belt 594, where the rotation driving member 591, the driving wheel 592, and the timing belt 594 are all disposed on the second connection assembly 57, and the timing belt 593 is drivingly connected between the rotation driving member 591 and the timing belt 594 to drive the timing belt 594 to rotate about the rotation axis, and the material taking member 54 is connected to the timing belt 594.

Further, the turning mechanism further includes a driven wheel, where the synchronous pulley 594 and the driven wheel are rotatably disposed on the third connection plate 574 around the rotation axis, and are respectively located on two opposite sides of the U-shaped structure, and two opposite sides of the material taking member 54 located between the U-shaped structures are respectively connected with the synchronous pulley 594 and the driven wheel, so as to drive the material taking member 54 to rotate around the rotation axis.

In practical application, tilting mechanism still includes take-up pulley 595, and take-up pulley 595 reciprocally movable sets up in third connecting plate 574, and is located between synchronous pulley 594 and 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 the tension of hold-in range 593 to prevent that hold-in range 593 from skidding.

Specifically, the rotation driving member 591 is a servo motor.

In some embodiments, the flipping apparatus 50 further comprises a first detection mechanism, both of which are electrically connected to the controller, the first detection mechanism being configured to detect a driven rotation angle of the timing pulley 594, and the rotational driver 591 being controlled by the controller to act according to the driven rotation angle.

The material taking member 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 member 54, so that the controller can control the rotation angle of the material taking member 54 according to the driven rotation angle of the synchronous pulley 594, so as to realize the overturning of the workpiece.

Further, the radial dimension of the driving wheel 592 is the same as the radial dimension of the synchronous pulley 594, the turnover mechanism further comprises a second detection mechanism and an adjustor, the second detection mechanism and the adjustor are electrically connected with the controller, the second detection mechanism is used for detecting the active rotation angle of the driving wheel 592, the adjustor is used for controlling the movement of the tensioning wheel 595, and the controller controls the adjustor to act according to the active rotation angle and the synchronous rotation angle, so that the synchronous belt 593 is tightly regulated.

Since the radial dimension of the driving pulley 592 is the same as the radial dimension of the timing pulley 594, in the case where the timing belt 593 is stably driven, that is, the timing belt 593 does not slip, the active rotation angle and the synchronous rotation angle are the same, and if the angles measured by the two detection mechanisms are different, it is indicated that the timing belt 593 has slip, the controller controls the regulator to adjust the tension roller so that the timing belt 593 is tensioned.

It should be noted that the synchronous pulley 594 and the driven pulley may be rotatably disposed on the third connecting plate 574 by a shaft matching with a bearing, and the implementation manner is relatively conventional, which is not described herein.

In addition, the radial dimension of the driving wheel 592 may be different from the radial dimension of the synchronous pulley 594, but the difference between the driving rotation angle and the synchronous rotation angle needs to be determined, that is, the operational relationship between the driving rotation angle and the synchronous rotation angle under normal conditions, and the controller obtains the driving rotation angle and the synchronous rotation angle and then determines whether the driving rotation angle and the synchronous rotation angle meet the preset operational relationship, if so, the driving wheel 592 is in normal operation, and if not, the driving wheel 592 is in slipping condition.

In some embodiments, the material taking member 54 and the absorbing member 524 are suction cups, and the corresponding turning device 50 is further provided with a negative pressure device and a connecting pipe, wherein the negative pressure device is electrically connected with the controller, and is respectively connected with the material taking member 54 and the absorbing member 524 through the connecting pipe, so as to generate negative pressure, thereby absorbing the workpiece.

In these embodiments, other structures of the turning device 50 are unchanged, but the first connecting component 53 is rotated to achieve the alignment position and the avoiding position of the material taking member 54, and those skilled in the art may perform structural design according to the implementation, which is not described herein.

In some embodiments, the second application device 70 has the same structure and function as the first application device 40, and is different from the first application device only in that it is located at a different station, so that the description thereof will be omitted.
