[0041] The utility model will be further explained in connection with the drawings and specific embodiments, so that the skilled in the art can better understand the utility model and can be implemented, but the embodiments are not as the limitation of the utility model.

[0042] In the comparative example, manual overturning is adopted, the plate is relatively thick and large, and six to seven or even seven to eight people are needed to carry the plate before each time of coiling, which is laborious and unsafe.

[0043] In some comparative examples, a plate turnover machine is used for overturning. The existing plate turnover machines include a bracket type plate turnover machine and a supporting roller type plate turnover machine.

[0044] The plate turnover machine includes a bracket, a rotating shaft and a motor. The motor drives the bracket rotating shaft to rotate, so as to overturn the plate by 180 degrees. When the bracket type plate turnover machine overturns the plate, the plate will fall off from the bracket when the overturning angle of the bracket exceeds 90 degrees, and directly fall on the supporting roller of the production line. The vibration of the plate is very large, sometimes a "bang, bang" sound can be heard, and the plate may be broken or the production line may be damaged. Especially for the plate with insufficient hardness, the damage is more serious. Therefore, this plate turnover machine may be difficult to pass the market test in the future.

[0045] The roller type plate turnover machine is used for bringing the plate into the circular arc support frame by the roller, and the circular arc support frame is rotated by the power device to rotate 180 degrees, so as to overturn the plate by 180 degrees. The roller type plate turnover machine is the most widely used turnover machine in recent years. The existing turnover machine is driven by the gear transmission to overturn the whole frame, or is driven by the rotating shaft to overturn the whole frame, or a plurality of plates or frames which are perpendicular to the cylinder are arranged on the surface of the cylinder, and the plates are overturned by the included angle between the plates. Due to the large area of the plate, the equipment is heavy, the gear transmission is affected by the working conditions, speed, load, material heat treatment and other factors, and the gear breaking, pitting, gear surface wear and other phenomena occur, so that the equipment is damaged, and the service life of the equipment is relatively low.

[0046] In order to solve the above problems, referring to Figures 1-8 The utility model discloses a plate turnover machine system, including portal crane, two turnover mechanisms 1000 and control mechanism.

[0047] Two turnover mechanisms 1000 are connected on the portal crane (not shown in the drawing) respectively, the portal crane drives the turnover mechanism 1000 to move up and down, and the portal crane drives two turnover mechanisms 1000 to move close to or away from each other along the X direction.

[0048] The turnover mechanism 1000 includes frame body 100, moving assembly 200, rotating block 300, connecting rod assembly 400 and sucking disc assembly 500. The frame body 100 is inverted U-shaped structure, the moving assembly 200 is arranged in the frame body 100, and the moving assembly 200 includes motor 210, lead screw 220 and lead screw nut 230. The motor 210 is connected with the frame body 100, the output shaft of the motor 210 is connected with one end of the lead screw 220 through the shaft coupling 250, the lead screw 220 is rotatably connected with the frame body 100, the lead screw nut 230 is matched with the lead screw 220, and the lead screw nut 230 moves along the X direction relative to the frame body 100. The rotating block 300 is arranged below the moving assembly 200 along the Z direction, and the rotating block 300 is rotatably connected with the frame body 100 through the rotating shaft 310. The connecting rod assembly 400 is movably connected with the lead screw nut 230 and the rotating block 300 at both ends respectively. The sucking disc assembly 500 is connected with the bottom of the rotating block 300 and is used for adsorbing the plate. The motor 210 drives the lead screw nut 230 to move along the X direction, and the rotating block 300 is rotated in the XZ plane under the action of the connecting rod assembly 400.

[0049] The working process of the turnover mechanism 1000 is as follows: the motor 210 drives the lead screw 220 to rotate, so as to drive the lead screw nut 230 to move reciprocatingly along the X direction. The reciprocating movement of the lead screw nut 230 is converted into the rotation of the rotating block 300 around the rotating shaft 310 in the XZ plane (vertical plane) under the action of the connecting rod assembly 400, so as to realize the 0°~90° rotation of the plate adsorbed on the sucking disc assembly 500.

[0050] The control mechanism is electrically connected with the motor 210, the suction cup assembly 500 and the gantry cradle. Thus, the control mechanism controls the gantry cradle to realize the up-and-down movement of the turnover mechanism 1000 (i.e. in the Z direction) and the mutual approach or departure of the two turnover mechanisms 1000 (i.e. movement in the X direction along the entire turnover mechanism 1000). In addition, the turnover of the two turnover mechanisms 1000 can be controlled respectively by the control mechanism to realize the docking of the two turnover mechanisms 1000.

[0051] In use, the two turnover mechanisms 1000 (i.e. the first turnover mechanism 1001 and the second turnover mechanism 1002) are arranged face to face (i.e. the ends of the two turnover mechanisms 1000 provided with the rotating blocks 300 are arranged close to each other) and then connected on the gantry cradle. First, the first turnover mechanism 1001 is adsorbed at the front of the board at the O° position, and then rotated to the 90° position. At this time, the second turnover mechanism 1002 has been rotated to the 90° position. Then the control mechanism controls the second turnover mechanism 1002 and the first turnover mechanism 1001 to move along the X direction so as to approach each other until the second turnover mechanism 1002 is adsorbed at the back of the board. Then the suction cup assembly 500 of the first turnover mechanism 1001 removes the adsorption of the board, and then the second turnover mechanism 1002 rotates to the O° position with the board (at this time, the first turnover mechanism 1001 rotates to the O° position for adsorption of the next board), so as to turn over the board. Finally, the board is transported to the board processing area.

[0052] Specifically, through the cooperation of the two turnover mechanisms 1000, in the turnover process, the turnover mechanism 1000 converts the rotation of the motor 210 into movement in the X direction through the lead screw 220 and the lead screw nut 230, and then converts the translation of the lead screw nut 230 into the rotation of the rotating block 300 through the connecting rod assembly 400, so as to realize the rotation of the board at 0°~90°. The rotation angle of each turnover mechanism 1000 is relatively small. In addition, the board is adsorbed and fixed by the suction cup assembly 500, so that the board will not fall off in the process of turnover. Secondly, the application realizes high transmission efficiency, stable movement, small structure and long service life. The application realizes automatic mechanical turnover, strengthens the safety factor, saves time and effort, and improves work efficiency; reduces labor cost.

[0053] Further, the application further comprises a guide assembly 600, which comprises a guide rail 610 and a sliding block 620; the guide rail 610 is connected to the bottom of the first connecting plate 110 (described below).

Specifically, the guide assembly 600 in the embodiment improves the guiding effect of the back-and-forth movement of the lead screw nut 230.

[0054] Further, the guide assembly 600 is two, and the two guide assemblies 600 are symmetrically arranged along the Y direction on both sides of the frame body 100. Specifically, the guiding effect is better.

[0055] Further, the suction cup assembly 500 comprises a suction cup support 510 and a plurality of suction cups 520 connected to the bottom of the suction cup support 510; the suction cup support 510 is connected with the rotating block 300 through the suction cup 520 connecting seat. In some embodiments, the suction cup 520 is four, and the four suction cups 520 are arranged at the four corners of the bottom of the suction cup support 510. Specifically, a plurality of suction cups 520 are used to adsorb and fix the plate, so as to avoid the situation that the plate falls due to the insecure adsorption during the process of turning over the plate.

[0056] Further, the frame body 100 comprises a first connecting plate 110, a first side plate 120 and a second side plate 130; the first side plate 120 and the second side plate 130 are symmetrically arranged on both sides of the bottom of the first connecting plate 110; the moving assembly 200 is connected to the bottom of the first connecting plate 110; and the rotating block 300 is in rotational connection with the first side plate 120 and the second side plate 130.

One end of the connecting rod 410 is hingedly connected with the lead screw nut 230, and the other end is hingedly connected with the rotating block 300. Specifically, the embodiment converts the sliding of the lead screw nut 230 into the rotation of the rotating block 300 through the hinging of the two connecting rods 410 with the lead screw nut 230 and the rotating block 300, which is simple in structure and reduces the cost.

[0058] Further, the moving assembly 200 further comprises a double-ear sliding seat 260; the double-ear sliding seat 260 comprises a sliding seat body 261 and two ears 262; the sliding seat body 261 is connected with the bottom of the screw nut 230; the two ears 262 are arranged on the two sides of the bottom of the sliding seat body 261, and the two ears 262 are movably connected with the connecting rod assembly 400.

The connecting rod assembly 400 further comprises a sliding shaft 420 for connecting the two connecting rods 410, the sliding shaft 420 is connected between the two ears 262, and the sliding shaft 420 and the sliding groove 141 form a sliding pair. In some embodiments, the second connecting plate 140 is arranged in parallel with the first connecting plate 110, and the second connecting plate 140 is connected between the first side plate 120 and the second side plate 130. Specifically, the sliding groove 141 and the sliding shaft 420 matched with the sliding groove 141 are arranged in the embodiment, so that the sliding of the end of the two connecting rods 410 connected with the screw nut 230 is always in the horizontal plane, so that the rotation of the rotating block 300 in the XZ plane (vertical plane) is not skewed, so that the board is turned more smoothly.
