The flipping module 5 is adjacent to the positioning module, fixing the annular part 8 and driving it to flip 180° before placing the flipped annular part 8 back onto the positioning module. The orientation discrimination module is located below the positioning module and determines whether the annular part 8 has been flipped by detecting whether it is facing forward or backward. Through these modules, automated flipping and orientation discrimination of the annular part 8 can be achieved, reducing manual processing time and labor costs.

[0041] Furthermore, such as Figures 1-3 As shown, in this embodiment, the front / back discrimination module includes: a first measuring cylinder 3, which is vertically fixed on the support platform 1 and positioned below the placement plate 22. The placement plate 22 has an opening opposite to the first measuring cylinder 3. When performing front / back discrimination, the piston rod of the first measuring cylinder 3 passes through the opening and connects with the annular part 8. The front / back of the annular part 8 is determined based on the stroke of the piston rod. Since the annular part 8 has some feature points, the distance from these feature points to the upper and lower end faces of the annular part 8 is different. The first measuring cylinder 3 is a high-precision stroke readable cylinder. After contacting the annular part 8, the specific stroke of the cylinder can be fed back. The front / back of the annular part 8 is determined based on the different strokes of the cylinder, thereby determining whether the annular part 8 has been flipped.

[0042] Specifically, such as Figures 1-3 As shown, in this embodiment, the detection module includes: a through-beam sensor 41 and a pair of mounting brackets 42; the pair of mounting brackets 42 are arranged opposite each other on both sides of the positioning module; the transmitting end and the receiving end of the through-beam sensor 41 are respectively fixed on the pair of mounting brackets 42; the through-beam sensor 41 detects the presence or absence of the annular part 8 on the positioning module; when the through-beam sensor 41 detects that the annular part 8 is in place, it triggers the subsequent flipping action and the front-back discrimination action.

[0043] Specifically, such as Figures 1-3As shown, in this embodiment, the flipping module 5 includes: a pair of horizontal drive units, a pair of lifting units, and a pair of flipping units; the pair of horizontal drive units are fixed on the support platform 1 and symmetrically arranged on both sides of the positioning module; the pair of lifting units are respectively fixed at the output ends of the pair of horizontal drive units, and the pair of flipping units are respectively fixed at the output ends of the pair of lifting units; the horizontal drive units drive the lifting units to move closer to or away from the positioning module, the lifting units drive the flipping units to move up and down, and the flipping units clamp the annular part 8 and drive the annular part 8 to flip 180°. Through the flipping module 5, the clamping and fixing of the annular part 8 and the flipping of its front and back sides are automatically realized.

[0044] Furthermore, such as Figures 1-3 As shown, in this embodiment, the horizontal drive unit includes: a guide rail 51, a slider 52, and a drive cylinder 53; the guide rail 51 and the drive cylinder 53 are horizontally fixed on the support platform 1, and the piston rod of the guide rail 51 and the drive cylinder 53 are parallel to each other; the slider 52 is slidably disposed on the guide rail 51; the lifting unit is fixed on the slider 52 and connected to the output end of the drive cylinder 53; the drive cylinder 53 drives the lifting unit to slide along the guide rail 51 to move closer to or away from the positioning module. The guide rail 51 provides guidance for the movement direction of the lifting unit and enhances the stability of the connection.

[0045] Furthermore, such as Figures 1-3 As shown, in this embodiment, the lifting unit includes: a rodless cylinder 54, which is vertically fixed to the output end of the horizontal drive unit. The output end of the rodless cylinder 54 is connected to the tilting unit to drive the tilting unit to lift.

[0046] Furthermore, such as Figures 1-3 As shown, in this embodiment, the flipping unit includes: a rotary cylinder 55 and a V-shaped gripper 56; the rotary cylinder 55 is fixed to the output end of the lifting unit; the V-shaped gripper 56 is fixed to the output end of the rotary cylinder 55; the V-shaped gripper 56 clamps and fixes the annular part 8, and the rotary cylinder 55 drives the V-shaped gripper 56 to rotate 180° vertically, thereby causing the annular part 8 to flip 180°, realizing the flipping of the front and back of the annular part 8, so as to carry out subsequent processes.

[0047] Furthermore, such as Figures 1-3As shown, in this embodiment, it further includes: a pair of second measuring cylinders 6, which are fixed on the support platform 1. The center of the pair of second measuring cylinders 6 and the annular part 8 are located on the same straight line. The piston rods of the pair of second measuring cylinders 6 extend out and connect with the annular part 8. The outer diameter of the annular part 8 is determined according to the stroke of the piston rods of the pair of second measuring cylinders 6. The second measuring cylinders 6 are high-precision stroke-readable cylinders. The two second measuring cylinders 6 are pushed out from both sides of the annular part 8 and stop after contacting the outer circle of the annular part 8. The specific stroke of the cylinder can be fed back. The outer diameter of the annular part 8 is determined according to the stroke of the cylinder, thereby distinguishing the type of annular part 8 with different outer diameters.

[0048] Furthermore, such as Figures 1-3 As shown, in this embodiment, it also includes: a push-out cylinder 7, which is fixed on the support platform 1. The push-out cylinder 7 pushes the annular part 8 that has been flipped away from the positioning module, so as to realize the discharge of the annular part 8 after flipping and distinguishing the front and back, and to carry out the next process.

[0049] This ring-shaped part flipping and discrimination mechanism is designed to handle multiple models of ring-shaped parts 8 and can be applied to automated processing production lines. It is achieved by the coordinated operation of multiple cylinders: When the conveyor places the ring-shaped part 8 on the placement plate 22, the through-beam sensor 41 detects that the ring-shaped part 8 has arrived. The drive cylinders 53 on both sides extend and drive the rodless cylinder 54, the rotary cylinder 55, and the V-shaped gripper 56 to move closer to the ring-shaped part 8. The V-shaped gripper 56 clamps the ring-shaped part 8. The two second measuring cylinders 6 extend and measure the outer diameter of the ring-shaped part 8 to determine its type and model. After the two second measuring cylinders 6 retract, the two rodless cylinders 54 lift the rotary cylinder 55, the V-shaped gripper 56, and the ring-shaped part 8 away from the placement plate 22. Then, the two rotary cylinders 55 rotate simultaneously to flip the ring-shaped part 8. The two rodless cylinders 54 then lower the rotary cylinder 55 and the ring-shaped part 8. After the through-beam sensor 41 receives a signal, the first measuring cylinder 3 extends and detects the feature point to determine whether the flipping is complete. When everything is complete, the ejection cylinder 7 ejects the ring-shaped part 8, achieving automatic discharge.
