[0020] The features of the present application and other related features are further described in detail by the following examples for the understanding of the skilled in the art:

[0021] As shown in Figures 1 to 3 , a rotary table type conveying device includes a base 1, the base 1 is rotatably connected with a rotary table 2 rotating around a vertical shaft, the base 1 is also provided with a driving motor 3 for driving the rotary table 2 to rotate intermittently, the rotary table 2 is provided with a plurality of workstations 21 uniformly distributed around the circumference and extending out of the base 1, each workstation 21 is provided with a limiting seat 4, the limiting seat 4 surrounds a square limiting area 41 for placing a workpiece, each workstation 21 is also provided with a flexible clamp 5 for pushing the workpiece to the edge of the limiting area 41, the flexible clamp 5 always has a tendency to push the workpiece and does not need to be driven by electricity / gas, the base 1 is provided with two unlocking mechanisms 6 arranged adjacent to each other along the circumference, the unlocking mechanism 6 is used to drive the flexible clamp 5 above it to open so as to facilitate the workpiece to enter the limiting area 41.

[0022] The rotary table conveying device of the present application includes a base 1, the base 1 is provided with a rotary table 2 rotating around a vertical shaft driven by a driving motor 3, and the rotary table 2 is provided with a plurality of workstations 21 arranged circumferentially, and each workstation 21 is respectively provided with a limiting seat 4 and a flexible clamp 5. One of the two unlocking mechanisms 6 is located at the feeding position and the other is located at the discharging position, and the feeding and discharging positions are adjacent.

[0023] When the rotary table conveying device works, the unlocking mechanism 6 at the feeding position opens the flexible clamp 5 on the work station 21 at the feeding position, so that the external equipment or the feeding personnel can place the sheet-shaped workpiece into the corresponding limiting area 41. After the workpiece is placed, the unlocking mechanism 6 can be reset, so that the flexible clamp 5 can push the workpiece in the limiting area 41 to fix the workpiece in the limiting area 41. After the workpiece is fixed, the driving motor 3 drives the rotary table 2 to rotate, and the work station 21 with the workpiece enters the next area to facilitate the external equipment to process the workpiece, and the next empty work station 21 enters the feeding position to repeat the feeding step. The work station 21 can be transferred to the position corresponding to the next processing procedure to facilitate the processing of the workpiece in a flow line after the workpiece completes all the preset processing procedures. The workpiece is rotated to the discharging position. When the work station 21 corresponding to the completed workpiece is rotated to the discharging position, the unlocking mechanism 6 at the discharging position drives the corresponding flexible clamp 5 to open, so that the external equipment or the discharging personnel can take out the processed workpiece in the limiting area 41 to complete the discharging. When the rotary table 2 rotates next time, the empty work station 21 with the taken-out workpiece rotates to the feeding position for feeding. Thus, the rotary table conveying device can complete the processing of the sheet-shaped workpiece in a flow line.

[0024] As described above, the rotary table conveying device sets the universal square limiting area 41 on the limiting seat 4 for processing the sheet-shaped product, and the workpiece placed in the limiting area 41 is further clamped by the flexible clamp 5. The flexible clamp 5 used in the present application can push and fix the workpiece without being driven by electricity or gas, so that the flexible clamp 5 can rotate with the rotary table 2 without electricity or gas circuit. The unlocking mechanism 6 for unlocking the flexible clamp 5 is fixedly arranged at the feeding and discharging positions and does not rotate with the rotary table, so that the complexity of the connecting structure between the base 1 and the rotary table 2 can be greatly reduced, and the cost of deploying the circuit or gas circuit can be greatly reduced.

[0025] As shown in Figures 1 to 2 Preferably, the limiting seat 4 includes a support block 42 for placing the workpiece thereon, and L-shaped limiting blocks 43 are respectively protruded at four corners of the surface of the support block 42. The L-shaped limiting blocks 43 jointly enclose the limiting area 41 on the surface of the support block 42. Thus, the limiting area 41 for placing the workpiece can be formed by the cooperation of the support block 42 and the L-shaped limiting blocks 43, and the workpiece can be fixed on the work station 21 by the pushing of the flexible clamp 5.

[0026] As shown in Figures 1 to 4, preferably, the flexible clamp 5 comprises a first guide rail 51 arranged on the rotating disc 2 between the rotating shaft of the rotating disc 2 and the corresponding limiting seat 4, a clamping block 52 capable of moving radially away from / close to the corresponding limiting seat 4 is connected to the first guide rail 51, a return spring 53 for driving the clamping block 52 to move towards the limiting seat 4 is also fixed on the rotating disc 2, the end of the clamping block 52 close to the corresponding limiting seat 4 is provided with a clamping surface 521 capable of moving in and out of the limiting area 41 along with the clamping block 52, and the moving path of the clamping surface 521 passes between the two L-shaped limiting blocks 43 close to the rotating shaft of the rotating disc 2 so as to push the workpiece to the wall surface of the other two L-shaped limiting blocks 43 away from the rotating shaft of the rotating disc 2.

[0027] As described above, the flexible clamp 5 can drive the clamping block 52 to move radially along the rotating disc 2 and keep the tendency of moving towards the limiting seat 4 through the cooperation of the first guide rail 51 and the return spring 53, and the clamping surface 521 capable of moving in and out of the limiting area 41 along with the clamping block 52, so as to continuously provide the workpiece in the limiting area 41 with a pushing force without the need of electric or gas driving, thereby pressing the workpiece in the limiting area 41 to achieve the fixation of the workpiece. When the work station 21 rotates to the feeding position or the discharging position, the clamping block 52 is additionally driven by the unlocking mechanism 6 to overcome the elastic force of the return spring 53, so as to move the clamping block 52 away from the limiting seat 4 and make the clamping surface 521 exit the limiting area 41, so that the workpiece can freely enter and exit.

[0028] As Figures 1 to 4 , preferably, the clamping block 52 above the clamping surface 521 is also provided with a pressing part 522 protruding towards the limiting area 41 for limiting the upward movement of the workpiece, so that in addition to pushing and pressing the workpiece in the limiting area 41 to the wall surface of the L-shaped limiting block 43 through the clamping surface 521, the workpiece can also be pressed in the limiting area 41 from above through the pressing part 522, thereby avoiding the upward and downward displacement of the workpiece during the machining process.

[0029] As Figure 4 indicated, preferably, the positions of the clamping block 52 and the limiting seat 4 capable of contacting the workpiece are covered with buffer rubber pads 7, so as to reduce the pressure on the workpiece due to the pressing and reduce the probability of damage to the workpiece.

[0030] As Figures 1 to 4As shown, preferably, the turntable 2 below the clamping block 52 is provided with a hollow groove 22 extending in the same direction as the first guide rail 51. The bottom of the clamping block 52 is provided with a wedge-shaped driven rod 523 extending downward through the hollow groove 22. The bottom surface of the wedge-shaped driven rod 523 gradually extends downward from the side near the limiting seat 4 towards the rotating shaft side of the turntable 2. The unlocking mechanism 6 includes a bracket 61 located below the turntable 2. A drive cylinder 62 is fixed on the bracket 61. A slide 63 is fixed on the piston rod of the drive cylinder 62. A second guide rail 64 is provided on the bracket 61 for the slide 63 to be limited and connected to move up and down on it. The slide 63 can rise and contact the wedge-shaped driven rod 523 that has rotated to its top and drive it to move away from the limiting seat 4.

[0031] As described above, the turntable 2 below the clamping block 52 is provided with a hollow groove 22 extending in the same direction as the first guide rail 51, and the bottom of the clamping block 52 is provided with a wedge-shaped driven rod 523 extending downward and passing through the hollow groove 22. At the same time, the unlocking mechanism 6 of this invention includes a slide 63 that can move up and down in cooperation with the drive cylinder 62 and the second guide rail 64. When station 21 rotates to the loading or unloading position, the drive cylinder 62 actuates to drive the slide 63 to rise. The slide 63 then contacts the wedge-shaped driven rod 523. Since the bottom surface of the wedge-shaped driven rod 523 is inclined, when the slide 63 contacts the bottom surface of the wedge-shaped driven rod 523 and continues to rise, the wedge-shaped driven rod 523 will be squeezed by the slide 63 and move closer to the rotating shaft of the turntable 2. This will then drive the clamping block 52 to move away from the limiting seat 4, causing the clamping surface 521 to exit the limiting area 41. In this way, the clamping surface 521 can no longer clamp the workpiece within the limiting area 41, thus unlocking it. When the drive cylinder 62 drives the slide 63 to move downward, the clamping block 52, driven by the return spring 53, will also move back towards the limiting seat 4, maintaining the pushing trend.

[0032] like Figures 1 to 3 As shown, preferably, the slide 63 is rotatably connected to a bearing 65 or a rubber roller that facilitates rolling contact with the wedge-shaped driven rod 523. In this way, the slide 63 can contact the wedge-shaped driven rod 523 through the bearing 65 or the rubber roller. This rolling contact can effectively reduce contact friction and extend the life of the parts, while also making the contact process smoother and quieter.

[0033] like Figures 1 to 3 As shown, preferably, an upward-facing pressure sensor 66 is also fixed on the slide 63, and a stop 67 is provided on the bracket 61 to contact the pressure sensor 66 when the slide 63 rises to the preset highest position. In this way, by setting the pressure sensor 66 and the stop 67, the limit position of the slide 63 driven by the drive cylinder 62 can be better controlled, thereby indirectly controlling the opening range of the flexible clamp 5.
