[0002] In automated processing and assembly equipment, turntables are often used to continuously process or assemble workpieces, improving production continuity and efficiency. To further increase production efficiency, current turntable automated assembly equipment often adds more processing mechanisms to the turntable processing and assembly device.

[0003] For example, the Chinese invention patent application with publication number CN113682747A provides a linkage turntable processing device, which is equipped with a rotating component, a pushing component and a linkage component, so that while the turntable rotates, the pushing slider can be driven to move back and forth by the swinging part and the lifting part, so that the pushing slider can limit or clamp the battery on the fixture when the fixture moves into place, thereby improving the continuity of the overall production and processing, thereby improving the overall production and processing efficiency.

[0026] The present application provides a linkage type turntable assembly device, which realizes the intermittent rotation of the turntable and the linkage operation of the assembly execution component through a power mechanism, saves power source and improves the assembly synchronization accuracy.

[0027] Combine Figures 1 to 14 As shown, in one embodiment, the linkage turntable assembly device includes: Combine Figures 1 to 14 As shown, in one embodiment, the assembly device of the linkage turntable 400 includes: Stand 100; The power mechanism 200 is mounted on the platform 100 , and the power mechanism 200 outputs a rotational driving force. The power mechanism 200 is connected to a driving cam 210 , and the power mechanism 200 drives the driving cam 210 to rotate; The intermittent rotator 300 is mounted on the stand 100. The power mechanism 200 drives the inner roller 700 through the transmission assembly 660. The power mechanism 200 drives the intermittent rotator 300 to work and output intermittent rotation driving force. The turntable 400 is in transmission connection with the intermittent rotator 300, and the intermittent rotator 300 drives the turntable 400 to rotate intermittently; The swing lifting mechanism 500 is disposed above the turntable 400 and is in transmission connection with the driving cam 210 via a center rod 800. The connecting end 801 of the center rod 800 is connected to the swing lifting mechanism 500, and the driving end 802 of the center rod 800 is in transmission connection with the driving cam 210. The driving cam 210 drives the center rod 800 to reciprocate about the axis of the center rod 800, thereby driving the swing lifting mechanism 500 to oscillate periodically. The swing assembly 600 is in transmission connection with the power mechanism 200, and the power mechanism 200 drives the swing assembly 600 to swing. The swing end 632 of the swing assembly 600 is connected to the driving end 802 of the center rod 800 to drive the center rod 800 to move linearly and reciprocatingly along the axial direction of the center rod 800, thereby driving the swing lifting mechanism 500 to periodically move linearly and reciprocatingly. The power mechanism 200 synchronously drives the intermittent rotator 300 , the driving cam 210 and the swing assembly 600 .

[0028] The stand 100 is a supporting base for the assembly device of the linkage turntable 400 , and can provide fixed or rotating support for various mechanisms and components.

[0029] In this embodiment, the power mechanism 200 uses a motor as a rotational output driver. This motor can be combined with conventional output adjustment mechanisms, such as a speed reducer and a direction-changing gear set, to adjust the output speed, torque, and direction of the power mechanism 200 to meet actual operating requirements. In other embodiments, the power mechanism 200 can also use other power sources that can provide rotational output, such as a rotary cylinder.

[0030] Combine Figures 1 to 4 As shown, in this embodiment, the power mechanism 200 is installed on the side of the platform 100, the driving cam 210 and the swing assembly 600 are located inside the platform 100, the intermittent rotator 300 is fixedly installed on the table of the platform 100, the turntable 400 and the swing lifting mechanism 500 are arranged above the intermittent rotator 300, and the center rod 800 vertically connects the swing lifting mechanism 500 and the driving cam 210 from top to bottom.

[0031] In other embodiments, the relative positions of the components and mechanisms may be adjusted according to different assembly requirements, such as arranging the center rod 800 horizontally or diagonally.

[0032] Combine Figures 3 to 5 As shown, in this embodiment, the swing lifting mechanism 500 includes a lifting plate 510 and a swing plate 520. The lifting plate 510 is located above the turntable 400, and the swing plate 520 is located above the lifting plate 510; the lifting plate 510 is movably engaged with the connecting end 801 of the center rod 800, and the lifting plate 510 moves back and forth along the axial direction of the center rod 800 along with the center rod 800, and the lifting plate 510 and the center rod 800 rotate relative to each other; the swing plate 520 is fixedly connected to the connecting end 801 of the center rod 800, and the swing plate 520 moves linearly and swings periodically along with the center rod 800.

[0033] In this embodiment, the turntable 400, the lifting plate 510 and the swing plate 520 are all configured as circular flat plate structures; in other embodiments, the turntable 400, the lifting plate 510 and the swing plate 520 can be individually or uniformly configured as other plate structures, such as a quadrilateral structure, a hexagonal structure, an octagonal structure, an elliptical structure or other plate structures.

[0034] Among them, combined Figure 14 As shown, in order to achieve the movable engagement between the lifting plate 510 and the center rod 800 , in this embodiment, the lifting plate 510 is movably connected to the center rod 800 via a bearing sleeve 511 .

[0035] By setting the bearing sleeve 511, the center rod 800 will not generate circumferential force on the lifting plate 510 when rotating around the axis, and when the center rod 800 moves linearly in the axial direction, it can drive the lifting plate 510 to move synchronously.

[0036] Specifically, the bearing sleeve 511 can be disposed at the center of the lifting plate 510 so that the lifting plate 510 is not easily shaken during movement.

[0037] Combine Figure 7 and Figure 14 As shown, in order to achieve a fixed connection between the swing plate 520 and the center rod 800, in this embodiment, a fastener 803 is fixedly provided at the connection end 801 of the center rod 800, and the swing plate 520 is sleeved on the fastener 803. Bolts can be used to fix the swing plate 520 and the fastener 803.

[0038] During operation, the wobble plate 520 needs to oscillate back and forth for a long time and many times. This constant shaking may cause the fasteners 803 and bolts to loosen. Therefore, to strengthen the fixation, the connection end 801 of the center rod 800 is further provided with a threaded section 810, which can be fastened to the wobble plate 520 above the fastener 803 by tightening the nut 811.

[0039] Combine Figure 2 、 Figure 6 and Figure 7 As shown, in this embodiment, the turntable 400 is provided with a plurality of workstations 410 for installing workpiece positioning tools arranged along the circumference, and the lifting plate 510 is provided with a plurality of execution components 512 for performing assembly actions arranged along the circumference; the swing plate 520 is linked with the execution component 512, and the swing plate 520 drives the execution component 512 to perform the telescopic action.

[0040] Specifically, the workstation area 410 may be provided with a workstation mounting hole 411 , and a fixture or a jig for fixing a workpiece may be installed in conjunction with the workstation mounting hole 411 to facilitate assembly or processing of the workpiece.

[0041] In the assembly device of the linkage turntable 400 of the present application, multiple workstations 410 and actuators 512 can be provided to perform continuous rotation processing or assembly. The rotation and displacement of the workstations 410 and the movement of the actuators 512 are coordinated to achieve continuous and efficient processing or assembly.

[0042] In this application, with the center of the turntable 400 as the center, each workstation area 410 is evenly distributed on the same circumference of the turntable 400; with the center of the lifting plate 510 as the center, each execution component 512 is evenly distributed on the same circumference of the lifting plate 510.

[0043] Combine Figure 6As shown, in this embodiment, the actuator 512 includes a slide rail 513 fixedly set on the lifting plate 510 and a slider 514 slidingly engaged with the slide rail 513, and the slider 514 is provided with a guide column 515; the swing plate 520 is provided with a guide groove 521, and the upper part of the guide column 515 is movably accommodated in the guide groove 521. When the swing plate 520 swings, the guide groove 521 drives the guide column 515 to move, thereby driving the slider 514 to telescopically move relative to the axis of the lifting plate 510.

[0044] In this embodiment, the guide groove 521 has an S-shaped path. This curved path helps provide a guiding force to the guide post 515 through the guide groove 521 when the wobble plate 520 swings, thereby driving the slider 514 to extend or retract. In other embodiments, the guide groove 521 may also have other shapes, such as an oblique line or an arc.

[0045] In this embodiment, in order to prevent foreign objects from falling onto the swing plate 520 and causing damage and to prevent people from accidentally touching it, a cover plate 522 may be provided above the swing plate 520 .

[0046] In this application, the slider 514 of the actuator assembly 512 can be equipped with an actuator (not shown). The actuator can include a pick-and-place mechanism such as a suction cup or a clamp, as well as other processing or assembly mechanisms such as a screw installer, a glue dispenser, and a spot welder, to meet various processing and assembly requirements.

[0047] For example, a suction cup can be installed on the slider 514. When the slider 514 extends outward under the action of the rocking plate 520, the suction cup can suck up parts; when the slider 514 is retracted to above the work station area 410 under the action of the rocking plate 520, the suction cup can place the sucked parts on the workpiece to be assembled in the work station area 410.

[0048] Furthermore, in different execution components 512 of the same linkage turntable 400 assembly device, the same or different execution mechanisms can be installed on the execution components 512 to achieve multiple different actions to be performed synchronously in each linkage.

[0049] For example, the loading clamp is installed on the No. 1 actuator 512, the suction cup is installed on the No. 2 actuator 512, the glue dispenser is installed on the No. 3 actuator 512, and the unloading clamp is installed on the No. 4 actuator 512. The actuators 512 move synchronously and cooperate with the workpiece fixture installed on the turntable 400 to perform different operations on the workpiece at each station. The action examples are as follows: The No. 1 actuator 512 clamps the workpiece from the external workpiece feeding mechanism and places it on the No. 1 workpiece fixture. The turntable 400 rotates to move the No. 1 workpiece fixture below the No. 2 actuator 512. Actuator assembly No. 2 512 picks up the part from the external part feeding mechanism and places it on the workpiece of workpiece fixture No. 1. Actuator assembly No. 1 512 again picks up the workpiece from the external part feeding mechanism and places it on workpiece fixture No. 2. The turntable 400 rotates, moving workpiece fixture No. 1 to below actuator assembly No. 3 512, and the other workpiece fixtures shift synchronously. The No. 3 actuator 512 performs glue dispensing on the workpiece on the No. 1 workpiece fixture, the No. 2 actuator 512 performs the part suction and placement action, and the No. 1 actuator 512 performs the workpiece picking action; The No. 4 actuator 512 takes the workpiece from the No. 1 workpiece fixture and places it on the external material receiving mechanism, while the other actuators 512 perform their respective actions; By executing the corresponding actions in sequence, synchronous operation of multiple stations can be achieved.

[0050] Among them, the feeding mechanism and the receiving mechanism can be conventional conveyor belts, feeding trays, feeding fixtures and other devices for placing workpiece materials.

[0051] Combine Figure 5 and Figure 6 As shown, in this embodiment, the power mechanism 200 is provided with a driving shaft 201 for outputting a rotational driving force, and the driving cam 210 is fixedly provided on the driving shaft 201, and the driving cam 210 rotates with the driving shaft 201; one end of the driving shaft 201 is connected to the transmission component 660; the driving inner roller; 700 and the swing component 600.

[0052] Recombination Figure 8 As shown, in this embodiment, the driving end 802 of the center rod 800 is inserted into a swing seat 820, and the swing seat 820 is rotatably connected to a base 830. The swing seat 820 is provided with a swing rolling pair 821. The driving cam 210 is protruded and wrapped with a curved portion 211. The swing rolling pair 821 is coupled with the curved portion 211. When the driving cam 210 rotates, the curved portion 211 cooperates with the swing rolling pair 821 to drive the swing seat 820 to swing, thereby driving the center rod 800 to swing.

[0053] The base 830 is provided in the platform 100 as a supporting foundation for supporting the center rod 800 and components such as the lifting plate 510 and the swing plate 520 connected to the center rod 800. The swing seat 820 and the base 830 can be rotatably connected through a bearing.

[0054] In this embodiment, the rocking and rolling pair 821 is two rollers rotatably disposed on the base 830 , and is clamped on both sides of the curved portion 211 of the driving cam 210 to form a coupling connection.

[0055] In this embodiment, the curved portion 211 protrudes from the drive cam 210 around the axis of the drive shaft 201. When the drive cam 210 rotates, the curved portion 211 applies a lateral force to the rocking and rolling pair 821, causing the rocking and rolling pair 821 to deflect and oscillate. The driving end 802 of the center rod 800 is inserted into the rocking seat 820. When the rocking seat 820 swings, it simultaneously drives the center rod 800 to reciprocate around its axis, thereby driving the rocking plate 520 to oscillate.

[0056] Combine Figures 8 to 12 As shown, in this embodiment, the rocking assembly includes a flat wheel 610, a rocking shaft 620, a rocking arm 630, a lifting roller 640, a driving outer roller 650 and a driving inner roller. The flat wheel 610 is fixedly arranged on the driving shaft 201, and an outer ring portion 611 is protruding laterally on the outer periphery of the flat wheel 610; the rocking shaft 620 is rotatably arranged on the platform 100, and the connecting portion 631 of the rocking arm 630 is fixedly connected to the rocking shaft 620. The rocking end 632 of the rocking arm 630 away from the connecting portion 631 is rotatably arranged to set the lifting roller 640, and the arm body of the rocking arm 630 is rotatably arranged to drive the outer roller 650 and the driving inner roller. The driving outer roller 650 abuts against the outer peripheral wall of the outer ring portion 611, and the driving inner roller abuts against the inner peripheral wall of the outer ring portion 611; the driving end 802 of the center rod 800 is provided with a lifting clamping portion 840, and the lifting clamping portion 840 clamps the lifting roller 640.

[0057] Specific, combined Figure 12 As shown, in this embodiment, the flat wheel 610 is a non-circular wheel-shaped structure, and different parts of its outer ring portion 611 have different inner diameters. When the flat wheel 610 rotates, it cooperates with the driving outer roller 650 and the driving inner roller to drive the swing arm 630, so that the swing arm 630 can swing up and down around the swing axis 620, and then the lifting and lowering part 840 is lifted or lowered by the lifting rolling part 640, so that the center rod 800 fixedly connected to the lifting and lowering part 840 is lifted and lowered accordingly.

[0058] In this embodiment, an air-avoidance cavity 612 is provided inside the outer ring portion 611 of the flat wheel 610. The air-avoidance cavity 612 can reduce the weight of the flat wheel 610 on the one hand, and avoid interference with the driving inner roller and other components on the other hand.

[0059] Combine Figure 6 As shown, in this embodiment, the lifting clamping part 840 includes an upper clamping part 841 and a lower clamping part 842, and the upper clamping part 841 and the lower clamping part 842 are respectively fixedly mounted on the outer wall of the center rod 800, and the lifting rolling part 640 is located between the upper clamping part 841 and the lower clamping part 842.

[0060] Specifically, the upper clamping member 841 and the lower clamping member 842 are both configured as an annular plate structure. When the center rod 800 rotates back and forth, since the upper clamping member 841 and the lower clamping member 842 extend outward, the upper clamping member 841 and the lower clamping member 842 can maintain contact with the lifting rolling member 640, thereby preventing the lifting rolling member 640 from being loosened by the lifting clamping part 840.

[0061] In this embodiment, the lifting plate 510 and the rocking plate 520, connected to the center rod 800, can be vertically lifted and lowered by the swing assembly 600, thereby driving the actuator 512 to rise and fall. Furthermore, the rocking plate 520 can rock under the rocking action of the drive cam 210 on the center rod 800, thereby driving the slider 514 to extend and retract. By implementing a pick-up or assembly mechanism on the slider 514 of the actuator 512, a continuous movement is achieved.

[0070] In this application, the intermittent rotator 300 can convert the continuous rotation inputted via the transmission assembly 660, the driving inner roller 700, into an intermittent rotation output, thereby driving the turntable 400 to intermittently rotate. Specifically, the intermittent rotator 300 can drive the turntable 400 to achieve a "rotate-stop-rotate-stop" periodic intermittent rotation according to pre-set rotation and stop durations.

[0071] Among them, in this embodiment, the intermittent rotator 300 adopts a cam indexer, which is a conventional intermittent rotation output mechanism.
