However, this method has great restrictions on the plate, that is, it is difficult to match the plate with a width of less than 150mm; furthermore, if the size of the customer's product plate varies greatly, it is necessary to frequently adjust the distance of the flipping support arms, so that automated and efficient operation cannot be achieved, which will result in higher labor costs.

[0019] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0020] like Figure 1 and Figure 2 As shown, an adaptive flipping system for automatic bending machine includes a vacuum suction cup 1, a pneumatic clamp 2, an upper support arm 3, a lower support arm 4, a main box (including a main bracket 5 and an upper cover 50), a gear 6, a rack 7 and a linear guide 8, wherein the linear guide is fixed in the main box, one end of the upper support arm and the lower support arm are respectively slidably connected to the linear guide through a slider 9, a rack is respectively fixed on the upper support arm and the lower support arm, and the two racks are respectively meshed with the two sides of the gear, and when the gear rotates, the two racks can be driven to move synchronously, thereby increasing or decreasing the distance between the upper support arm and the lower support arm to adapt to plates of different sizes.
[0021] In this device, the gear is mounted on the main housing and driven by a driving mechanism. The driving mechanism can be selected from two structures. One is as follows: Figure 3 As shown, the driving mechanism is a motor 12 and a reducer 13, and the motor is connected to the driving shaft of the gear through the reducer. Figure 4 As shown, the driving mechanism is a hand wheel 14, which is connected to a driving shaft 15 of a gear.
[0022] The vacuum suction cups are installed on the upper support arm and the lower support arm respectively, and the pneumatic clamps are installed on the upper part of the upper support arm. Specifically, the vacuum suction cups on the upper support arm and the lower support arm are symmetrically positioned and face the same direction. In the device, each support arm has at least three vacuum suction cups for adsorbing larger plates. There are at least two pneumatic clamps, and the two pneumatic clamps can clamp small plates.
[0023] like Figure 5 As shown, in order to accurately know the distance between the upper support arm and the lower support arm, a ruler 10 is provided on the main box body, and corresponding pointers 11 are provided on the corresponding upper support arm and the lower support arm.
[0024] In order to make the overall structure more stable, the bottom of the main box is fixed on the base 16. The base is fixed to the ground by bolts.
[0025] In order to make the plate more stable when it is placed on the suction cup, the main box is tilted and fixed on the base. The main body is at an angle of 100° to the horizontal plane, which can increase the stability of the plate from the structural point of view, enhance safety, and reduce the outer diameter of the vacuum suction cup. When in use, the plate is placed on the vacuum suction cup in the device by the manipulator, and then the manipulator takes the plate from the other side to achieve the purpose of turning it over. If it is a small plate, it is placed on the pneumatic clamp.
[0026] When in use, if the driving mechanism is a servo motor, the servo motor drives the gear to rotate, and the gear drives the rack to move in opposite directions, thereby realizing a single motor driving the upper support arm and the lower support arm. If the driving motor is a hand wheel, the hand wheel drives the gear to rotate, and the gear drives the rack to move in opposite directions. The air source enters the three-position five-way pneumatic solenoid valve through the air pipe collection box. The solenoid valve outputs two air paths, one of which is connected to the vacuum pump unit, and then connected to the upper support arm and the lower support arm respectively through the drag chain and the vacuum logic valve, and then the air pipes are connected to the vacuum suction cup respectively; the other air path is connected to the upper support arm through the drag chain, and then connected to the pneumatic gripper respectively; the pneumatic principle has the ability to maintain vacuum for a period of time after "power failure" and "gas failure", and will not cause the plate to fall immediately after "power failure" and "gas failure". At the same time, the vacuum logic valve will also minimize the leakage of vacuum. This pneumatic system greatly increases safety and reliability.
[0027] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
