The present application discloses a flipping device for a stamped part 99, wherein the stamped part 99 includes a bent sheet and an intermediate connecting post. The flipping device includes a flipping support assembly 1 and a flipping assembly 2. The flipping assembly 2 is rotatably mounted on the flipping support assembly 1. The flipping assembly 2 flips the stamped part 99 onto the flipping support assembly 1 in preparation for the next step of movement. Figure 1 and Figure 2 To facilitate understanding of the relevant position of the stamped part 99, the stamped part 99 is drawn on both the flipping bracket assembly 1 and the flipping assembly 2. However, in the actual process, the stamped part 99 is only present in one location.

[0023] Please refer to Figure 6 The flipping component 2 includes a rotating pin 21; please refer to... Figure 3 and Figure 4This application presents a perspective view and a front view of a tilting bracket assembly. The tilting bracket assembly 1 includes a slider base plate 11, a first side plate 12 with a connecting through hole and a second side plate 13 with a U-shaped notch, a roller bearing 14 for connecting the rotating pin 21 in the connecting through hole of the first side plate 11, a lifting cylinder 15 for lifting on the slider base plate 11, a cylinder connecting plate 16, a positioning block connecting plate 17, and a positioning block 18 sequentially arranged on the piston rod of the lifting cylinder 15, with the first side plate 12 and the second side plate 13 connected to each other at both ends. 3. A limiting plate 19 for limiting position, a side plate connecting plate 110 disposed between the first side plate 12 and the second side plate 13 for stable connection, and a positioning plate 111 disposed on the side plate connecting plate 110 for receiving the stamped part, wherein the positioning block 18 has a contoured surface for receiving the stamped part 99; in this embodiment, the first side plate 12 and the second side plate 13 are disposed on the slider base plate 11 and are fixedly connected by fasteners; the positioning block 18 includes a middle notch, which is mainly designed to avoid the middle connecting post of the stamped part 99, so that after flipping, the middle connecting post of the stamped part 99 is located at the positioning block 111. The notch in the middle of block 18 facilitates extraction by the robotic arm; the contoured surface of the positioning block 18 and the end face of the positioning plate 111 allow the stamped part 99 to be at a suitable angle for extraction by the robotic arm. Additionally, the lifting cylinder 15 extends its piston rod to lift the stamped part 99 to the position where it can be extracted by the robotic arm, and the limiting plate 19 limits the rising height of the positioning block connecting plate 17, while also determining the extension height of the piston rod of the lifting cylinder 15. The limiting plate 19 is a U-shaped sheet with openings on both sides, and a waist-shaped through hole is provided at the bend for fastening the connection between the first side plate 12 and the second side plate. Plate 13; In addition, the two ends of the side plate connecting plate 110 are respectively fixedly connected to the first side plate 12 and the second side plate 13 by fasteners to increase the stability of the flip bracket assembly 1. The positioning plate 111 is an elongated piece with an oblong hole. The fasteners can adjust the height of the positioning plate 111 by locking it onto the side plate connecting plate 110 through the oblong hole. The end of the positioning plate 111 facing the stamping part 99 is bent to increase the area of ​​the stamping part 99. After the stamping part 99 moves to the positioning block 18, it abuts against the stamping part 99 to limit it on the positioning block 18 to prevent it from falling.

[0024] Please refer to Figure 5 and Figure 8The flipping bracket assembly 1 further includes a buffer 112 and a buffer fixing block 113 disposed on the second side plate 13 for fixing the buffer 112; the flipping device further includes a base assembly 3, the base assembly 3 includes a base plate 31 and a limiting block 32 disposed on the base plate 31 for limiting the buffer 112. This application uses an Airtac AC1412 type buffer. The position of the buffer 112 corresponds to that of the limiting block 32. When the flipping bracket assembly 1 is subjected to force and moves, the buffer 112 moves toward the limiting block 32. When the two are in contact, the buffer 112 provides a buffering force to ensure the stability of the stamped part 99 on the positioning block 18.

The drive disc shaft of the rotary cylinder 28 is connected to the connecting through hole of the second flipping plate 23. The first flipping plate 22 is rotatably connected to the roller bearing 14 disposed on the first side plate 12 via the rotating pin 21. Figure 6 As shown, the number of positioning pins 27 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 28 is used for swinging and rotating actions. The drive disc shaft of the rotary cylinder 28 passes through the U-shaped notch and is fixedly connected to the connecting through hole of the second flip plate 23. Figure 1As shown, the first flipping plate 22 and the second flipping plate 23 are located inside the first side plate 12 and the second side plate 13. Both the first flipping plate 22 and the second flipping plate 23 are shaped like a vertical sheet plus an annular sheet. The vertical sheet is used to connect the flipping positioning plate 24, 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 28 is fixed to the outside of the second side plate 13. The rotary cylinder 28 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 28 passes through the U-shaped notch of the second side plate 13 before being fixedly connected to the connecting through hole of the second flipping plate 23. During the flipping process, the drive disc shaft of the rotary cylinder 28... Figure 1 The clockwise rotation of the central axis drives the second flipping plate 23, the flipping positioning plate 24, and the stamping part 99 to rotate, thus conveying the stamping part 99 out. After conveying, the drive disc shaft of the rotary cylinder 28 rotates counterclockwise to return the second flipping plate 23 and the flipping positioning plate 24 to their original positions, ready to receive the next stamping part 99; Figure 1 and Figure 6 As shown, one end of the rotating pin 21 of this application is fixedly connected to the second flip plate 23, and the other end of the rotating pin 21 is inserted into and connected to the roller bearing 14. The purpose of connecting the rotating pin 21 to the roller bearing 14 is to enable the first flip plate 22 to rotate smoothly.

After 18, before the stamped part 99 is lifted, the moving cylinder 35 pushes the flipping bracket assembly 1 out to the position to be picked up by the robotic arm. At this time, the buffer 112 reaches the limit block 32. When the two are in contact, the buffer 112 provides a buffering force to ensure the stability of the stamped part 99 on the positioning block 18. After the stamped part 99 is grasped by the robotic arm, the piston rod of the moving cylinder 35 retracts, and the flipping bracket assembly 1 returns to the initial position to prepare for the next flipping process. The combination of the two sliders 114 and the two slide rails 33 enables the flipping bracket assembly 1 to move smoothly.

[0027] like Figure 8 As shown, the flipping device also includes a solenoid valve assembly 4 disposed on the moving cylinder connecting plate 34 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 35, the rotary cylinder 28 and the lifting cylinder 15, to complete the flipping, moving and lifting of the stamping part 99, and the return of the flipping bracket assembly 1 to the initial position.
