The popularization of "machine replacement" is also driving the development of high-tech manufacturing. Automatic machine handling is an indispensable device in the automatic production line. In order to improve the efficiency of handling, the handling machine must carry multiple workpieces at the same time. However, in conventional factories, the grasping position of the workpiece is fixed, and the distance between the workpieces is also fixed. Therefore, the distance and size of the grasping parts of the handling machine are also fixed. However, in reality, there are also cases where the workpieces are placed in different positions. When the production line adjusts the position of the workpiece according to needs, the handling machine is very likely to be unable to match it, causing production obstacles.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and are therefore not to be construed as limitations on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and are not to be construed as indicating or implying relative importance.

[0021] Example:

[0022] Reference Figure 1 Combined with Figure 2 , a handling device, comprising a pneumatic gripper 1 and a moving assembly 2; the pneumatic gripper 1 is mounted on the moving assembly 2;

[0023] The moving assembly 2 includes a cylinder 21, an active component 22, a transmission component 23 and a driven component 24; the active component 22 includes a first rack 221 and a third rack 222; the transmission component 23 includes a driving gear 231 and a driven gear 232; the driving gear 231 and the driven gear 232 are coaxially fixedly connected; the first rack 221 and the third rack 222 are both meshed with the driving gear 231; the first rack 221 and the third rack 222 are symmetrically arranged with the driving gear 231 as the center; the body of the cylinder 21 is fixedly connected to the third rack 222 through a first connecting member 25; the output shaft of the cylinder 21 is fixedly connected to the first rack 221 through a second connecting member 26;

[0024] The driven component 24 includes a second rack 241 and a fourth rack 242; the second rack 241 and the fourth rack 242 are both meshed with the driven gear 232; the second rack 241 and the fourth rack 242 are symmetrically arranged with the driven gear 232 as the center; the teeth of the first rack 221 and the teeth of the second rack 241 extend in the same direction, that is, if the first rack 221 meshes with the driving gear 231 downward, the second rack 241 also meshes with the driven gear 232 downward, ensuring that the movement direction of the first rack 221 is the same as that of the second rack 241; there are four pneumatic jaws 1, which are respectively mounted on the first rack 221, the second rack 241, the third rack 222 and the fourth rack 242.

[0025] The output shaft of the cylinder 21 is initially retracted, and when the output shaft of the cylinder 21 is pushed out, the body and output shaft of the cylinder 21 both generate balanced and relative thrusts, pushing the first connecting member 25 and the second connecting member 26, driving the first rack 221 and the third rack 222 to move in opposite directions, and the distance between the pneumatic clamping jaws 1 on the first rack 221 and the third rack 222 gradually increases; the first rack 221 and the third rack 222 are respectively meshed with the upper and lower positions of the driving gear 231, and can simultaneously drive the driving gear 231 to rotate, and the driving gear 231 drives the driven gear 232 to rotate in the same direction, and the second ... The rack 241 and the fourth rack 242 are respectively meshed at the upper and lower positions of the driven gear 232, so the second rack 241 and the fourth rack 242 also move in opposite directions. The movement direction of the second rack 241 is the same as that of the first rack 221, and the movement direction of the fourth rack 242 is the same as that of the third rack 222. The distance between the pneumatic clamp 1 on the second rack 241 and the fourth rack 242 also gradually increases, forming a long-spacing distribution pattern. For workpieces with a longer clamping spacing, the pneumatic clamp 1 opens to clamp the workpiece, controls the handling device to move to the placement area, and the pneumatic clamp 1 retracts and puts down the workpiece. The working principle of the pneumatic clamp 1 and the movement of the handling device are both conventional technologies.

[0026] The output shaft of the cylinder 21 retracts, driving the first connecting member 25 and the second connecting member 26 to pull the first rack 221 and the third rack 222 to move in the direction of the driving gear 231. The driving gear 231 rotates to drive the driven gear 232, and the second rack 241 and the fourth rack 242 also retract in the direction of the driven gear 232. The distance between the pneumatic clamping jaws 1 on the first rack 221, the second rack 241, the third rack 222 and the fourth rack 242 is shortened to form a short-spacing distribution pattern. For workpieces with a shorter clamping spacing, the pneumatic clamping jaws 1 open and clamp the workpiece, and the handling device is controlled to move to the placement area, and the pneumatic clamping jaws 1 are retracted to put down the workpiece.

[0027] The extension and retraction of the cylinder 21 can be controlled by a controller, and the control process is conventional technology.

[0028] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the present invention.
