[0029] like Figures 1 to 3 As shown, this embodiment provides a rotary processing device 100, including a rotary table 10, a drive assembly 40, and multiple clamping assemblies 20.

[0030] The rotary table 10 has a defined rotation axis V, and the rotary table 10 can rotate around the rotation axis V. The drive assembly 40 is connected to the rotary table 10 and is configured to drive the rotary table 10 to rotate intermittently. That is, after rotating the rotary table 10 by a preset angle, the rotary table 10 stops rotating, and after a preset time, it continues to rotate by the preset angle and repeats the above action.

[0031] Multiple clamping assemblies 20 are connected to the rotary table 10 and are spaced apart around the rotation axis V. Each clamping assembly 20 holds a workpiece, allowing the workpiece to pass through different processing stations and undergo different processing operations as it rotates with the rotary table 10. Each clamping assembly 20 includes a first clamping mechanism 21, a second clamping mechanism 22, a transmission mechanism 24, and a clamping drive member 23. The first clamping mechanism 21 is configured to clamp the workpiece along a first direction Y, and the second clamping mechanism 22 is configured to clamp the workpiece along a second direction X. The first direction Y is parallel to the length direction of the clamping assembly 20 and parallel to the radial direction of the rotary table 10.

For example, the rotating table 10 is driven to rotate by 90° and then stopped, so that the workpiece completes machining at the current machining station. The rotating dividing member 42 is only used to realize intermittent rotation of the rotating table 10.

[0056] The position detection assembly 50 comprises a photoelectric sensor 51 and a rotating disc 52. The rotating disc 52 is coaxially connected to the input shaft 421, and the input shaft 421 can drive the rotating disc 52 to rotate synchronously when the input shaft 421 rotates. The photoelectric sensor 51 is installed on the housing of the rotating dividing member 42. In the rotating process of the rotating disc 52, the edge region of the rotating disc 52 is always located between the emitting end and the receiving end of the photoelectric sensor 51, and the photoelectric sensor 51 can shield the detection laser emitted by the emitting end through the rotating disc 52.

[0057] In particular, the edge of the rotating disc 52 is provided with a positioning opening 520. When the edge area of the rotating disc 52 provided with the positioning opening 520 is rotated to between the emitting end and the receiving end of the photoelectric sensor 51, the detection laser emitted by the emitting end can pass through the positioning opening 520 and be received by the receiving end, and then a detection signal can be emitted. The initial position of the input shaft 421 can correspond to the position of the rotary table 10 rotated to the workpiece feeding position, or can be designed as other positions according to actual requirements.
