[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0026] like Figures 1 to 4 As shown, the utility model provides a flipping device, which includes a fixed seat 1, a flip frame 2 rotatably connected to the fixed seat 1, a flip driving mechanism 3 installed on the fixed seat 1 and used to drive the flip frame 2 to flip, a lifting mechanism 4 arranged below the flip frame 2, at least one first clamping mechanism 5 installed on the inner wall of one side plate of the flip frame 2, a pulling mechanism 6 installed on the other side plate of the flip frame 2 and at least one second clamping mechanism 7 installed on the pulling end of the pulling mechanism 6, the first clamping mechanism 5 and the second clamping mechanism 7 are arranged opposite to each other, the pulling mechanism 6 is used to drive the second clamping mechanism 7 to approach or move away from the first clamping mechanism 5, and the lifting end of the lifting mechanism 4 can extend into the flip frame 2. Specifically, the flip driving mechanism 3 can adopt a motor.

[0027] In actual application, the lifting end of the lifting mechanism 4 is extended into the flip frame 2, the clamping end of the first clamping mechanism 5 and the clamping end of the second clamping mechanism 7 are both in an open state, an external manipulator or a manual operation places a sheet (such as a PCB board, etc.) on the lifting end of the lifting mechanism 4, and the lifting mechanism 4 lifts and supports the sheet, and both sides of the sheet are respectively located in the clamping end of the first clamping mechanism 5 and the clamping end of the second clamping mechanism 7, then the clamping end of the first clamping mechanism 5 and the clamping end of the second clamping mechanism 7 are closed, so that the clamping end of the first clamping mechanism 5 and the clamping end of the second clamping mechanism 7 respectively clamp both sides of the sheet, and then the lifting end of the lifting mechanism 4 is moved out from the bottom of the flip frame 2 until the lifting end of the lifting mechanism 4 and the flip frame are aligned. The space between the frames 2 can be used for the flipping frame 2 to flip. At the same time, the pulling end of the pulling mechanism 6 drives the second clamping mechanism 7 to pull the sheet away from the first clamping mechanism 5 according to a preset program, so that the sheet is subjected to an appropriate horizontal pulling force to ensure that the sheet is always straight and prevent the middle part of the sheet from sagging and deforming due to gravity. The flipping drive mechanism 3 drives the flipping frame 2 to flip the clamped sheet 180°, so that the front and back sides of the sheet are swapped to achieve flipping of the sheet; after the sheet is flipped, the lifting end of the lifting mechanism 4 extends into the flipping frame 2 and lifts and supports the flipped sheet, then the first clamping mechanism 5 and the second clamping mechanism 7 release their clamping of the sheet, and an external robot or manual labor takes away the flipped sheet. The utility model applies a pulling force to the sheet material through the pulling mechanism 6 while realizing the flipping of the sheet material, thereby ensuring the straightness of the sheet material and preventing the middle part of the sheet material from sagging and deformation, thereby ensuring the quality of the sheet material, and supports the sheet material through the lifting mechanism 4, which is convenient for taking and placing the sheet material.

[0028] In this embodiment, the pulling mechanism 6 includes at least one pulling module 8 installed on the flip frame 2, and one pulling module 8 is drivingly connected to one second clamping mechanism 7. Each pulling module 8 independently controls one second clamping mechanism 7, so that the same or different pulling forces can be applied to different positions of the sheet.

[0029] In this embodiment, the pulling module 8 includes a pulling cylinder 9 installed on the flip frame 2 and a pulling plate 10 installed on the piston rod of the pulling cylinder 9, and the second clamping mechanism 7 is installed on the pulling plate 10. In actual application, the pulling cylinder 9 drives the pulling plate 10 to move the second clamping mechanism 7 in a direction away from the first clamping mechanism 5, so that the second clamping mechanism 7 applies a horizontal pulling force to the sheet material clamped by it.

[0030] In this embodiment, the first clamping mechanism 5 or / and the second clamping mechanism 7 include a pneumatic clamping jaw 11 and two clamping blocks 12 respectively mounted on the pneumatic clamping jaw 11, and the pneumatic clamping jaw 11 is used to drive the two clamping blocks 12 to open or close. Specifically, the pneumatic clamping jaw 11 adopts a Y-shaped cylinder. In actual application, the pneumatic clamping jaw 11 drives the two clamping blocks 12 to open or close like scissors to achieve the release and clamping of the sheet.

[0031] Preferably, the clamping surface of the clamping block 12 is provided with a protective pad made of elastic material, which provides buffering protection for the sheet material to avoid pinching the sheet material.

[0032] In this embodiment, the lifting mechanism 4 includes a base 13, a lifting drive 14 installed on the base 13, and a lifting plate 15 installed on the lifting end of the lifting drive 14. The lifting drive 14 is used to drive the lifting plate 15 to rise and fall. The first clamping mechanism 5 and the second clamping mechanism 7 are respectively located outside the two sides of the lifting plate 15; specifically, the lifting drive 14 can use a cylinder.

[0033] In actual application, the lifting driver 14 drives the lifting plate 15 to move up and down, so that the lifting plate 15 extends into the flip frame 2 or moves out to the bottom of the flip frame 2 .

[0034] In this embodiment, a guide rod 16 is installed on the bottom surface of the lifting plate 15, and the guide rod 16 slides through the base 13. In the process of lifting the lifting plate 15, the guide rod 16 plays a guiding role, thereby improving the stability of the lifting plate 15 in lifting.

[0035] In this embodiment, the base 13 is equipped with a damper 17, and the damping end of the damper 17 is used to abut against the bottom surface of the lifting plate 15. When the lifting plate 15 is lowered to the limit position, the damper 17 abuts against the bottom surface of the lifting plate 15 to prevent the lifting plate 15 from excessively descending and causing a hard impact collision with the base 13.

[0036] In this embodiment, the lifting plate 15 is provided with a four-way positioning mechanism. In practical applications, after an external manipulator or a person places a sheet on the lifting plate 15, the four-way positioning mechanism positions the sheet, ensuring the position accuracy and stability of the sheet on the lifting plate 15, which is conducive to the first clamping mechanism 5 and the second clamping mechanism 7 being able to stably clamp the sheet.

[0037] In this embodiment, the four-way positioning mechanism includes four positioning modules 18, which are respectively located on the four sides of the lifting plate 15. The positioning module 18 includes a positioning cylinder 19 installed on the bottom surface of the lifting plate 15, a piston rod installed on the positioning cylinder 19 and a movable plate 20 installed on the bottom surface of the lifting plate 15, and a plurality of positioning rods 21 installed on the movable plate 20. The positioning rod 21 is located outside the side of the lifting plate 15, and the top of the positioning rod 21 is higher than the top surface of the lifting plate 15. The first clamping mechanism 5 or the second clamping mechanism 7 is staggered with the corresponding positioning rod 21. In actual application, after an external manipulator or a person places the sheet on the lifting plate 15, the positioning cylinder 19 drives the movable plate 20 to move with the positioning rod 21 close to the side of the lifting plate 15, so that the positioning rod 21 contacts the side of the sheet and positions the sheet.

[0038] In this embodiment, clamping avoidance grooves 22 are provided on both sides of the lifting plate 15, and the clamping end of the first clamping mechanism 5 or the clamping end of the second clamping mechanism 7 can be located in the corresponding clamping avoidance grooves 22. In practical applications, the clamping avoidance grooves 22 provide avoidance space for the clamping end of the first clamping mechanism 5 or the clamping end of the second clamping mechanism 7, and in the process of lifting the lifting plate 15 being raised or lowered, interference between the lifting plate 15 and the clamping end of the first clamping mechanism 5 or the clamping end of the second clamping mechanism 7 is avoided, and the structure of the lifting plate 15 and the clamping end of the first clamping mechanism 5 or the clamping end of the second clamping mechanism 7 is made compact.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
