[0043] The support assembly 1 comprises a center shaft 11, a one-way bearing 12 is sleeved on the center shaft 11, an outer ring of the one-way bearing 12 is sleeved with a center gear 13, and one end of the center shaft 11 is fixedly connected with a support frame 14;

[0044] The platform assembly 2 is rotatably connected with the support frame 14, the platform assembly 2 is provided with a driven wheel 20, and the platform assembly 2 is used for placing a workpiece;

[0045] The driving mechanism 4 is used for driving the driving wheel 3 to rotate;

[0046] The feeding mechanism comprises a revolution state and a rotation state:

[0047] When the driving wheel 3 rotates in the first direction, the feeding mechanism is in the revolution state, the center gear 13 drives the center shaft 11 to rotate, and the center shaft 11 drives the support frame 14 and the platform assembly 2 to rotate;

[0048] When the driving wheel 3 rotates in the second direction, the feeding mechanism is in a rotation state, the driving gear is engaged with the driven wheel 20, and the platform assembly 2 rotates.

[0049] As shown in Figure 1 , Figure 2 and Figure 3 , the driving wheel 3 can rotate in the clockwise or counterclockwise direction under the drive of the driving mechanism 4, the driving wheel 3 is engaged with the central gear 13, and the driving wheel 3 can always drive the central gear 13 to rotate. Since the central gear 13 is sleeved on the central shaft 11 through the one-way bearing 12, the one-way bearing 12 is a one-way rotating and reverse stopping bearing, so the central gear 13 can drive the central shaft 11 to rotate in a certain direction and will not drive the central shaft 11 to rotate in the reverse direction.

[0050] In a specific embodiment, the first direction is the clockwise direction, and the second direction is the counterclockwise direction, as shown in Figure 3 , when the driving wheel 3 rotates in the clockwise direction, it can drive the central gear 13 to rotate in the counterclockwise direction, and in turn drive the central shaft 11 to rotate.

It can be understood that at this time, the support frame 14 drives the platform assembly 2 and the driven wheel 20 to revolve, the driving wheel 3 is not engaged with the driven wheel 20, and in turn the driven wheel 20 will not rotate, that is, the platform assembly 2 will not rotate.

[0051] When the driving wheel 3 rotates in the counterclockwise direction, it can drive the central gear 13 to rotate in the clockwise direction, at this time the central shaft 11 does not rotate under the action of the one-way bearing 12, therefore the support frame 14 will not revolve, at this time the driving gear is engaged with the driven wheel 20, and the platform assembly 2 is rotationally connected with the support frame 14, in turn the driving wheel 3 can drive the driven wheel 20 to rotate, and in turn drive the platform assembly 2 to rotate.

[0066] The type and number of the brake 62 are not limited, the brake 62 can be a pneumatic brake 62, a point brake 62, etc., the feeding mechanism can be provided with two brakes 62, and the two brakes 62 are arranged along the circumference of the brake disc 61, the more the number of the brake 62 is, the better the braking effect on the brake disc 61 is.

[0067] Further, the feeding mechanism further comprises a detection assembly 7, and the detection assembly 7 comprises:

[0068] A detection piece 71 is arranged apart from the support assembly 1, and the working end of the detection piece 71 faces a detection station;

[0069] A detected piece 72 is arranged on the support assembly 1, and when the feeding mechanism is in revolution state, the detected piece 72 approaches or moves away from the detection station.

[0070] It should be noted that in operation, the detection piece 71 is electrically connected to the control system, the control system is electrically connected to the driving motor, when the feeding mechanism is in the revolution state, the support assembly 1 revolves and drives the detected piece 72 to rotate, and then the detected piece 72 can approach or move away from the detection piece 71, when the detected piece 72 is in the detection station, the detection piece 71 detects the detected piece 72 and transmits a signal to the control system, the control system controls the driving motor, and the driving motor makes the driving wheel 3 decelerate or stop, and then the detection assembly 7 is beneficial to the feeding mechanism to stop from the revolution state and convert to the rotation state.
