[0034] This embodiment discloses a U-shaped plate automatic forming device, Figure 1 As shown, it includes a conveyor belt 1, a first preforming mechanism 2, a second preforming mechanism 3 and a controller;

[0035] The first preforming mechanism 2 includes a first shaping cavity 4 arranged on the conveyor belt 1, a lifting plate 5 is arranged in the first shaping cavity 4, the conveyor belt 1 is provided with a stop plate 6 in its output direction, the stop plate 6 is located in front of the first shaping cavity 4 and prevents the sheet material 25 on the conveyor belt 1 from moving forward, an outlet 9 is opened at the top of the first shaping cavity 4, the lifting plate 5 can lift the sheet material 25 in the direction of the outlet 9, and the lifting plate 5 is connected to the controller. The conveyor belt 1 transfers the flat sheet material 25 to the first shaping cavity 4, and the sheet material 25 stops in the first shaping cavity 4 under the prevention of the stop plate 6, and the lifting plate 5 in the first shaping cavity 4 lifts the sheet material 25 on the conveyor belt 1, and under the action of the lifting plate 5 and the first shaping cavity 4, the two ends of the sheet material 25 are folded, and the sheet material 25 realizes the first automatic preforming.

[0036] The second preforming mechanism 3 includes a movable grasping manipulator 7. Above the grasping manipulator 7, there is a second shaping cavity 8. The second shaping cavity 8 can move towards the grasping manipulator 7 and press against the sheet material 25 on the grasping manipulator 7. Both the grasping manipulator 7 and the second shaping cavity 8 are connected to the controller. After receiving the signal that the first automatic preforming of the sheet material 25 is completed, the controller controls the grasping manipulator 7 to pull out the sheet material 25 in the first orientation cavity from the outlet 9 in the first shaping cavity 4. Then, the second shaping cavity 8 moves towards the grasping manipulator 7 and presses against the sheet material 25 on the grasping manipulator 7, enabling the second automatic preforming of the sheet material 25 and ensuring the forming effect of the sheet material 25.

[0037] In this embodiment, Figure 2 As shown, the first shaping cavity 4 includes first preforming limit plates 41 respectively arranged on both sides of the conveyor belt 1. The first preforming limit plates 41 on both sides are symmetrically arranged. One end of each first preforming limit plate 41 is fixed to the outer side edge of the conveyor belt 1, and the other end turns towards the inner side of the conveyor belt 1. There is a gap between the outer ends of the first preforming limit plates 41 on both sides, and this gap is the outlet 9. The first preforming limit plates 41 turn inwards on both sides of the conveyor belt 1 to form the required first shaping cavity 4, and the first preforming limit plates 41 cooperate with the lifting plate 5. When the lifting plate 5 rises, it can quickly and conveniently shape the sheet material 25.

[0038] In this embodiment, Figure 2 As shown, the first preforming limit plates 41 are located on both side edges of the output port of the conveyor belt 1, and the stop baffle 6 is arranged at the output port of the conveyor belt 1, making the structure of the first shaping cavity 4 simpler and more compact.

[0039] In this embodiment, Figures 3 - 4 As shown, the second shaping cavity 8 includes a mounting plate 10 above the grasping manipulator 7 and second preforming limit plates 81 respectively arranged on both sides of the mounting plate 10. The second preforming limit plates 81 on both sides are symmetrically arranged. The mounting plate 10 and the second preforming limit plates 81 form a second shaping cavity 8 that is convenient for forming a U shape, and the mounting plate 10 provides a mounting position for the second preforming limit plates 81.

[0040] In this embodiment, Figures 3 - 4 As shown, an adjusting cylinder 11 is arranged on the mounting plate 10. The adjusting cylinder 11 drives the mounting plate 10 to move towards or away from the grasping manipulator 7. The mounting plate 10 is also convenient for arranging the adjusting cylinder 11, enabling the telescopic shaft on the adjusting cylinder 11 to drive the mounting plate 10 to move towards or away from the grasping manipulator 7.

[0041] In this embodiment, Figures 3 - 4As shown, the grasping manipulator 7 is provided with a telescopic cylinder 16. The telescopic cylinder 16 drives the grasping manipulator 7 to move in the Z-axis direction, so that the material taking manipulator 23 moves in the Z-axis direction, facilitating the material taking manipulator 23 to grasp the sheet material 25 and place the formed sheet material 25 into the target box body 20.

[0042] In this embodiment, Figure 1 As shown, an X-axis slide rail 17 is provided above the conveyor belt 1. A Y-axis slide rail 18 is slidably connected to the X-axis slide rail 17. The second preforming mechanism 3 is slidably connected to the Y-axis slide rail 18. The X-axis slide rail 17 and the Y-axis slide rail 18 enable the second preforming mechanism 3 to move in the X direction and the Y direction, making the second preforming mechanism 3 move flexibly in space.

[0043] In this embodiment, Figure 1 As shown, a box body in-place sensor 19 is further provided below the X-axis slide rail 17. The controller is connected to the X-axis slide rail 17, the Y-axis slide rail 18, the grasping cylinder 15, the telescopic cylinder 16, and the adjusting cylinder 11 through the box body in-place sensor 19. The controller controls the movement of the second preforming mechanism 3 through the box body in-place sensor 19.

[0044] In this embodiment, Figure 2 As shown, an induction switch 21 is provided on the stop baffle 6. The induction switch 21 is connected to the conveyor belt 1. The controller is connected to the conveyor belt 1 through the induction switch 21. This induction switch 21 can stop the conveyor belt 1 to avoid wasting energy and affecting the accurate shaping of the sheet material 25.

[0045] In this embodiment, Figure 2 As shown, the conveyor belt 1 includes two parallel conveyor belts. The lifting plate 5 is arranged at the position between the two conveyor belts 1, facilitating the arrangement of the lifting plate 5.

[0046] In this embodiment, Figure 1 As shown, a sheet material storage box 22 and a material taking manipulator 23 are provided on the side of the conveyor belt 1. The material taking manipulator 23 moves the sheet material 25 in the storage box onto the conveyor belt 1, further improving the automation performance.

[0047] In this embodiment, Figure 5 As shown, the material taking manipulator 23 includes a connecting plate 231. A suction cup 232 is provided on the lower side of the connecting plate 231. The upper side of the connecting plate 231 is connected to the robot through a flange 233. The suction cup 232 is arranged on the connecting plate 231 to adapt to the structure of the sheet material 25, improving the stability of material taking.

[0048] In this embodiment, Figure 2As shown, a lifting induction switch is provided on the upper surface of the lifting plate 5. The lower surface of the lifting plate 5 is connected to a lifting cylinder 26. The controller is connected to the lifting cylinder 26 through the lifting induction switch. This lifting induction switch enables the lifting plate 5 to rise or fall according to whether there is a sheet material 25 placed on it. When there is no sheet material 25 on the plate surface of the lifting plate 5, the lifting plate 5 descends and resets.

[0049] The control process of the above U-shaped plate automatic forming device is as follows: The in-place sensor 19 of the box body 20 senses whether the box body 20 is in place. When it senses that the box body 20 is in place, the controller controls the Y-axis slide rail 18 to move on the X-axis slide rail 17, and controls the second pre-forming mechanism 3 to be located above the first pre-forming mechanism 2 on the Y-axis slide rail 18. Then the controller controls the telescopic cylinder 16 to drive the gripping manipulator 7 of the second pre-forming mechanism 3 to descend into the first shaping cavity 4. The controller controls the gripping cylinder 15 to drive the gripping manipulator 7 to grip the sheet material 25. Then the controller controls the telescopic cylinder 16 to contract, and the gripping manipulator 7 pulls the sheet material 25 out of the first shaping cavity 4. The controller controls the adjusting cylinder 11 to drive the mounting plate 10 to descend, so that the second pre-forming limit plate 81 presses against the sheet material 25 on the gripping manipulator 7 to complete the second pre-forming of the sheet material 25. Then the controller controls the gripping manipulator 7 to move above the box body 20 where the U-shaped plate is to be placed. When moving downward to the two ends of the U-shaped plate and loading it into the box body 20, the controller controls the adjusting cylinder 11 to drive the mounting plate 10 to drive the second pre-forming limit plate 81 away from the gripping manipulator 7. The gripping manipulator 7 continues to press down the U-shaped plate in the Z-axis direction. After the U-shaped plate is packed, the telescopic cylinder 16 drives the gripping cylinder 15 to move upward to complete the automatic forming and automatic packing of the U-shaped plate, and this cycle continues.

[0050] Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that, as Figures 3 - 4As shown in the figure, each of the second pre-forming limit plates 81 includes a swing rod 810 and a plate member 811 provided at the lower end of the swing rod 810. The upper end of the swing rod 810 is bent on the side facing away from the mounting plate 10 to form a connecting rod 812. A notch 13 is formed on the side of the mounting plate 10. The bent portion of the swing rod 810 is mounted on the notch 13 and is rotatably connected to the mounting plate 10 through a connecting pin 24. The outer end of the connecting rod 812 is connected to a forming cylinder 14. The telescopic rod of the forming cylinder 14 drives the connecting rod 812 to rotate around the connecting pin 24. When it is necessary to shape the U-shaped plate, the telescopic rod of the forming cylinder 14 is pushed outwards. The connecting rod 812 rotates and drives the lower end of the swing rod 810 to swing inwards. Here, the swing rods 810 on both sides simultaneously drive the plate members 811 thereon to swing inwards, and the two plate members 811 press the sheet material 25 into a U-shaped plate. When it is not necessary to shape the U-shaped plate, the telescopic rod of the forming cylinder 14 contracts. The connecting rod 812 rotates and drives the lower end of the swing rod 810 to swing outwards. Here, the swing rods 810 on both sides simultaneously drive the plate members 811 thereon to swing outwards, and the two plate members 811 release the U-shaped plate. The structure of the second pre-forming limit plate 81 can controllably adjust the configuration of the U-shaped plate.

[0052] In this embodiment, as Figures 3 - 4 shown, the grasping manipulator 7 includes a fixed clamping plate 71 and a movable clamping plate 72. The fixed clamping plate 71 and the movable clamping plate 72 are arranged opposite to each other. A grasping cylinder 15 is provided on the movable clamping plate 72. The grasping cylinder 15 drives the movable clamping plate 72 to move away from or close to the fixed clamping plate 71. The combined action of the fixed clamping plate 71 and the movable clamping plate 72 not only plays a role in grasping, but also can position the direction of the sheet material 25, facilitating the downward movement of the second shaping cavity 8 above the grasping manipulator 7 to shape the sheet material 25.

[0053] The distance between the movable clamping plate 72 and the fixed plate is perpendicular to the distance between the second pre-forming limit plates 81 on both sides, which facilitates the downward movement of the second shaping cavity 8 to shape the sheet material 25.

[0054] Other components of this embodiment are the same as those of Embodiment 1 and will not be described in detail here.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
