[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figure 1 The schematic diagram of the flipping device in this application shows that the flipping component is mounted on the flipping bracket assembly, so that the parts to be assembled and the fixtures are all mounted on the flipping bracket assembly. The parts can be flipped without removing them from the fixtures, which simplifies the operation and production structure and improves production efficiency. In addition, the flipping component of this application uses a rotary cylinder to flip the processed parts, which can meet various angle requirements.

[0027] like Figure 1 and Figure 2 As shown, the workpiece flipped by the flipping device of this application is a stamped part 99. The stamped part 99 includes a bent sheet and an intermediate connecting post. The flipping device includes a flipping support assembly 2 and a flipping assembly 3. The flipping assembly 3 is rotatably mounted on the flipping support assembly 2. The flipping assembly 3 flips the stamped part 99 onto the flipping support assembly 2 in preparation for the next step of movement. The flipping support assembly 2 includes a first side plate 23 with a connecting through hole and a second side plate 25 with a U-shaped notch. Additionally, please refer to... Figure 3 , Figure 4 and Figure 5The flipping assembly 3 includes a first flipping plate 31 with a connecting through hole, a second flipping plate 33 with a connecting through hole, a positioning plate 32 with an accommodating through hole disposed between the first flipping plate 31 and the second flipping plate 33, the first flipping plate 31 being rotatably connected to the first side plate 23 via a rotating shaft 34, an electromagnet 36 disposed in the accommodating through hole of the positioning plate 32 for magnetically attracting the stamped part 99, an electromagnet adjusting plate 35 disposed on the electromagnet 36 for adjusting the magnetic attraction force of the electromagnet 36, a plurality of positioning posts 38 disposed on the positioning plate 32 for positioning the stamped part 99, and a rotary cylinder 39 disposed on the second side plate 25 for rotating the second flipping plate 33, such as Figure 5 As shown, the number of positioning pins 38 in this embodiment is 5, but this cannot be used to limit this application. Any number capable of positioning the stamped part 99 should be within the scope of protection of this application. The rotary cylinder 39 is used for swinging and rotating actions. The drive disc shaft of the rotary cylinder 39 passes through the U-shaped notch and is fixedly connected to the connecting through hole of the second flip plate 33, as shown. Figure 2 As shown, the first flipping plate 31 and the second flipping plate 33 are located inside the first side plate 23 and the second side plate 25. Both the first flipping plate 31 and the second flipping plate 33 are shaped like a vertical sheet plus an annular sheet. The vertical sheet is used to connect the positioning plate 32, but this cannot be used to limit this application; any shape that does not affect rotation should be within the scope of protection of this application. The rotary cylinder 39 is fixed to the outside of the second side plate 25. The rotary cylinder 39 used in this application is an Airtac HRQ30A cylinder. The drive disc shaft requires a large rotation radius; therefore, the drive disc shaft of the rotary cylinder 39 passes through the U-shaped notch of the second side plate 25 before being fixedly connected to the connecting through hole of the second flipping plate 33. During the flipping process, the drive disc shaft of the rotary cylinder 39... Figure 1 The counterclockwise rotation of the central direction drives the second flip plate 33, positioning plate 32, and stamping part 99 to rotate, conveying the stamping part 99 out. After being conveyed out, the drive disc shaft of the rotary cylinder 39 rotates clockwise to return the second flip plate 33 and positioning plate 32 to their original positions, ready to receive the next stamping part 99; Figure 5 As shown, the rotating shaft 34 of this application is a circular shaft with a radially protruding annular plate at one end. The first side plate 23 is fixedly connected to one side of the rotating shaft 34, and the other side of the rotating shaft 34 is inserted into the connecting through hole of the first flip plate 31. The purpose of the rotating shaft 34 is to enable the first flip plate 31 to rotate smoothly.

[0028] Please refer to Figure 6 and Figure 7The flipping bracket assembly 2 further includes a slider base plate 21, a lifting cylinder 211 disposed on the slider base plate 21 for lifting, a cylinder connecting plate 26 disposed sequentially on the piston rod of the lifting cylinder 211, a positioning block connecting plate 28 and a positioning block 27, and a support block 29 disposed on the positioning block 27 for receiving the stamped part 99, as shown. Figure 7 As shown, the positioning block 27 has a contoured surface for receiving the stamped part 99; Figure 6 In this embodiment, the first side plate 23 and the second side plate 25 are disposed on the slider base plate 21 and are fixedly connected by fasteners; in this embodiment, there are two support blocks 29, and the positioning block 27 includes a middle notch. This design is mainly to avoid the middle connecting post of the stamping part 99; the contoured surface of the positioning block 27 and the support block 29 make the stamping part 99 form a suitable angle for being picked up by the robotic arm. In addition, the function of the lifting cylinder 211 is to extend the piston rod to lift the stamping part 99 to the position to be picked up by the robotic arm.

[0029] like Figure 6 As shown, the flip bracket assembly 2 also includes a connecting plate 210 disposed between the first side plate 23 and the second side plate 25 for a stable connection. The two ends of the connecting plate 210 are respectively fixedly connected to the first side plate 23 and the second side plate 25 by fasteners to increase the stability of the flip bracket assembly 2.

[0030] Please refer to Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 9 , Figure 2 and Figure 6 As can be seen from the above, the flip-up bracket assembly 2 also includes two sliders 22 disposed on the lower surface of the slider base plate 21; for example Figure 1 , Figure 8 and Figure 9As shown, the flipping device also includes a base assembly 1, which includes a base plate 11, two slide rails 13 on the base plate 11 for connecting the two sliders 22, a movable cylinder connecting plate 15 on the base plate 11, a movable cylinder 16 on the movable cylinder connecting plate 15 for moving the flipping bracket assembly 2, and two stiffening plates 12 for increasing the connection strength of the movable cylinder connecting plate 15. The piston rod of the movable cylinder 16 is connected to the flipping bracket assembly 2. After the stamping part 99 is moved to the positioning block 27, before the stamping part 99 is lifted, the movable cylinder 16 pushes the flipping bracket assembly 2 to the position to be picked up by the robotic arm. After the stamping part 99 is grasped by the robotic arm, the piston rod of the movable cylinder 16 retracts, and the flipping bracket assembly 2 returns to the initial position to prepare for the next flipping process. The combination of the two sliders 22 and the two slide rails 13 allows the flipping bracket assembly 2 to move smoothly.

[0031] like Figure 1 As shown, the flipping device also includes a solenoid valve assembly 4 disposed on the moving cylinder connecting plate 15 for providing an air source. The control center controls the opening and closing of the solenoid valve assembly 4, thereby controlling the movement of the moving cylinder 16, the rotary cylinder 39 and the lifting cylinder 211, to complete the flipping, moving and lifting of the stamping part 99, and the return of the flipping bracket assembly 2 to the initial position.
