[0017] like Figures 1-4As shown, this utility model embodiment provides an automatic folding device for use on a fully automatic ultrasonic AI vision triangular workpiece equipment, in conjunction with other devices on the equipment; including: a mounting base plate 1, a pressing mechanism 2 for pressing the webbing workpiece, a pressing cloth mechanism 3 for pressing the triangular workpiece, a first folding mechanism 4 for folding the triangular workpiece, a flipping mechanism 5 on the mounting base plate, and a second folding mechanism 6 connected to the flipping mechanism and cooperating with the first folding mechanism 4 for folding the triangular workpiece.

[0018] The mounting base plate 1 has several support rods 7 vertically connected to it on its bottom surface, which are used to mount the mounting base plate on the frame (not shown) of the fully automatic ultrasonic AI vision triangular workpiece equipment.

[0019] like Figures 5-7 As shown, specifically in this embodiment, the pressing mechanism 2 includes a pressing horizontal cylinder 202 fixed to the bottom surface of the mounting base plate 1, a pressing horizontal connecting plate 206 on the back of the pressing horizontal moving plate 202a on the pressing horizontal cylinder, a pressing vertical connecting plate 207 vertically disposed on one side of the pressing horizontal connecting plate and located outside the pressing horizontal cylinder 202, a pressing vertical cylinder 203 disposed on the vertical surface of the pressing vertical connecting plate, a pressing mounting plate 204 disposed at the upper end of the output shaft of the pressing vertical cylinder, and a pressing sheet 205 disposed on the upper surface of the pressing mounting plate and located on the upper surface of the mounting base plate; the mounting base plate 1 has a strip-shaped first through hole 101, and the pressing mounting plate 204 extends upward through the first through hole under the drive of the pressing vertical cylinder; the pressing horizontal connecting plate 206 and the pressing vertical connecting plate 207 are connected by integral molding. After the pressing horizontal cylinder 202 is activated, it drives the pressing horizontal moving plate 202a to move horizontally. The pressing horizontal connecting plate 206, pressing vertical connecting plate 207, pressing vertical cylinder 203, pressing mounting plate 204, and pressing sheet 205 move horizontally accordingly. After the pressing vertical cylinder 203 is activated, the pressing sheet 205 rises under the drive of the pressing mounting plate 204, moves horizontally, and reaches the end of the webbing that needs to be pressed. Then, the output shaft of the pressing vertical cylinder 203 retracts, causing the pressing mounting plate 204 and pressing sheet 205 to descend. The pressing sheet 205 then presses one end of the webbing onto the triangular workpiece. The pressing horizontal moving plate 202a is part of the pressing horizontal cylinder 202; that is, when the pressing horizontal cylinder is activated, it can drive the pressing horizontal moving plate to move horizontally.

[0020] like Figures 5-7As shown, specifically, the pressing mechanism 3 includes a left and right adjusting block 301 vertically fixed to the bottom surface of the mounting base plate 1, a pressing horizontal cylinder 302 on one of the vertical surfaces of the left and right adjusting blocks, a pressing vertical connecting plate 306 on the back of the pressing horizontal moving plate 302a on the pressing horizontal cylinder, a pressing vertical cylinder 303 on the back of the pressing vertical connecting plate, a pressing mounting plate 304 on the upper end of the output shaft of the pressing vertical cylinder, and a pressing block 305 on the upper surface of the pressing mounting plate; the mounting base plate 1 has a strip-shaped second through hole 102, and the pressing block extends upward through the first through hole under the drive of the pressing mounting plate 304. After the horizontal pressing cylinder 302 is activated, it drives the horizontal pressing plate 302a to move horizontally. The vertical pressing plate 306, the vertical pressing cylinder 303, the pressing mounting plate 304, and the pressing block 305 also move horizontally. After the vertical pressing cylinder 303 is activated, the pressing block 305 rises under the drive of the pressing mounting plate 304, moves horizontally, and reaches the two overlapping corners of the folded triangular workpiece that needs to be pressed. Then, the output shaft of the vertical pressing cylinder 303 retracts, causing the pressing mounting plate 304 and the pressing block 305 to descend. The pressing block 305 then presses the two overlapping corners of the folded triangular workpiece. The horizontal pressing plate 302a is part of the horizontal pressing cylinder 302; that is, when the horizontal pressing cylinder is activated, it can drive the horizontal pressing plate to move horizontally.

[0021] like Figures 5-7 As shown, specifically, the first folding mechanism 4 includes a first flipping suction block 401 disposed on the bottom surface of the mounting base plate 1, a first folding horizontal cylinder 402 disposed on the first flipping suction block, a first connecting plate 403 disposed at the end of the output shaft of the first folding horizontal cylinder, a first folding vertical cylinder 404 fixedly connected to the first connecting plate, a first vertical connecting plate 405 disposed at the end of the output shaft of the first folding vertical cylinder, a first folding piece 406 disposed on the upper surface of the first vertical connecting plate, and an optical fiber 407 vertically disposed on the bottom surface of the mounting base plate 1 and located on one side of the first flipping suction block 401; the mounting base plate 1 is provided with a third through hole 103, and the first folding piece 406 extends upward through the third through hole under the drive of the first vertical connecting plate 405.

[0022] like Figures 1-7 As shown, specifically, the flipping mechanism 5 includes: a rack fixing seat 501 with an internal mounting groove 501a, the opening of which is located inside the upper surface of the rack fixing seat and the upper surface of the rack fixing seat is fixed to the bottom surface of the mounting base plate 1; a flipping drive assembly; a gear and rack assembly connected to the flipping drive assembly; and a flipping assembly connected to the gear and rack assembly.

[0023] The flipping drive assembly includes a flipping drive cylinder 502 mounted on the bottom surface of the mounting base plate 1, a slider 503 whose bottom surface is fixedly connected to the bottom surface of the mounting groove 501a, a guide rail 504 mounted in the mounting groove and slidably connected to the slider, and a buffer 505 arranged along the length of the mounting groove with one end located in the mounting groove; the gear and rack assembly includes a rack 506 fixed on the upper surface of the guide rail 504 and connected at one end to the output shaft of the flipping drive cylinder 502, and a flipping bearing seat 507 mounted at one end of the fourth through hole 104 in the mounting base plate 1, with one section of the rack located in the flipping bearing seat and the other section located in the flipping bearing. The external rotating fixed shaft 508 can be understood as being divided into two sections, one of which is located inside the rotating bearing seat and the other is located outside the rotating bearing seat; the rotating gear 509, which is sleeved on the rotating fixed shaft and located inside the rotating bearing seat 507 and meshes with the rack 506; the snap ring 510, which is sleeved on the rotating fixed shaft 508 for axially limiting the rotating gear; the buffer 505 is used to buffer the rack 506; the rotating drive cylinder 502 is installed at one end of the rack fixed seat 501; and two rotating bearings 515 are located inside the rotating bearing seat 507 and sleeved on the rotating fixed shaft 508.

[0024] The flipping assembly includes a horizontally arranged flipping connecting strip 511, one end of which is connected to the bottom surface of the flipping fixed shaft 508 located outside the flipping bearing seat 507; a flipping folding plate 512, located on the upper surface of the flipping connecting strip and embedded in the fourth through hole 104 in the mounting base plate 1; a flipping guide seat 513, located on the upper surface of the mounting base plate 1 and outside the other end of the fourth through hole 104; and a flipping connecting shaft 514. One end of the flipping connecting shaft is inserted into the flipping guide seat and rotatably connected to the flipping guide seat, and the other end of the flipping connecting shaft is connected to the upper surface of the other end of the flipping connecting strip 511. A limiting block 516, located on the bottom surface of the mounting base plate 1 and outside one side of the flipping folding plate 512, is used to limit the flipping folding plate.

[0025] like Figures 1-7 As shown, specifically, the second folding mechanism 6 and the first folding mechanism 4 are arranged side by side to fold the side of the triangular workpiece together; the second folding mechanism 6 includes a second flipping suction block 601 disposed on the bottom surface of the flipping folding plate 512, a second folding horizontal cylinder 602 disposed on the second flipping suction block, a second connecting plate 603 disposed at the end of the output shaft of the second folding horizontal cylinder, a second folding vertical cylinder 604 fixedly connected to the second connecting plate, a second vertical connecting plate 605 disposed at the end of the output shaft of the second folding vertical cylinder, and a second folding piece 606 disposed on the upper surface of the second vertical connecting plate; the second folding piece 606 extends upward through the fourth through hole under the drive of the second vertical connecting plate 605.

[0026] The second folding mechanism 6 is arranged side by side with the first folding mechanism 4. In use, the triangular workpiece from the previous process (e.g., loading) is placed on the upper surface of the mounting base plate 1 and fixed. Then, the second folding horizontal cylinder 602 is activated, driving the second connecting plate 603 and the second folding vertical cylinder 604 to move horizontally. After reaching the folding position, the second folding vertical cylinder 604 is activated, driving the second vertical connecting plate 605 and the second folding piece 606 to move upwards to a predetermined height. The second folding vertical cylinder 604 continues to move horizontally and targets one of the triangular workpieces. The sides are folded. During this process, the action of the first folding mechanism 4 is consistent with that of the second folding mechanism 6. Here, a thin plate is used to press down the triangular workpiece, while the side to be folded is located outside the bottom surface of the thin plate. When the second folding plate 606 pushes the folding, the side of the triangular workpiece to be folded is equivalent to rolling back relative to the thin plate. After folding, the folded side is located on the upper surface of one side of the thin plate. At this time, the second folding plate 606 and the first folding plate 406 press the folded side tightly against the upper surface of one side of the thin plate. Then the thin plate is removed, and the first vertical... Connecting plate 405 and second vertical connecting plate 605 retract synchronously, pressing the folded side of the triangular workpiece against the upper surface of mounting base plate 1. Subsequently, one end of the webbing from the previous process is pressed against the surface of the triangular workpiece. At this time, half of the triangular workpiece is located on the upper surface of the flipping folding plate 512. The flipping drive cylinder 502 is activated, driving rack 506 to move forward, thereby driving flipping gear 509 to rotate. When flipping gear 509 rotates, it drives flipping fixed shaft 508 to rotate synchronously, thereby driving flipping connecting strip 511, flipping folding plate 512, and second folded edge. Mechanism 6 rotates accordingly, and the triangular workpiece is folded in half. When the flipping gear 509 rotates 180 degrees, the upper surface of the flipping folding plate 512 is in contact with the upper surface of the mounting base plate 1, thus completing the folding of the triangular workpiece. The half of the triangular workpiece located on the upper surface of the flipping folding plate 512 covers the surface of one end of the webbing. Then the pressing mechanism 3 is activated, and the pressing block 305 presses the two overlapping corners of the folded triangular workpiece together. The workpiece is then removed by other mechanisms on the fully automatic ultrasonic AI vision triangular workpiece equipment and proceeds to the next process.

[0027] like Figure 8 As shown, the triangular piece 8 is folded in half and combined with the webbing 9.
