A clamping strip for clamping contact with the wafer is installed on the lower surface of each end of the telescopic slider away from the push block; On the outer side of the lower end of the pushing block, several slope surfaces corresponding to the telescopic sliders are formed. Each of the slope surfaces inclines radially inwards from top to bottom. At one end of each telescopic slider close to the pushing block, a roller is installed.

An elastic belt 7 is sleeved and connected between a plurality of the connecting pins 6 and is in a tensioned state; Next, the second cylinder is driven to drive the connecting rod to drive the push block to move upward until it no longer contacts the roller installed on the telescopic slider. During this process, each telescopic slider moves synchronously towards the sheet under the action of the elastic belt until the clamping strips facing each other clamp the sheet; After clamping the workpiece, the support plate is driven by the first cylinder to move upward, and then the bracket is driven by an external conveying mechanism to move to the next station and release the workpiece.

[0029] The above-mentioned support plate 22 is mounted on the bracket 21 through at least one set of slide rails 16 and sliders 17.

[0038] The above-mentioned elastic belt 7 is a circular rubber belt.

[0039] The above-mentioned workpiece 100 is a metal lead frame.

[0040] The working principle of the present invention is as follows: In use, first, the bracket is driven by an external conveying mechanism to move above the workpiece to be carried, then the support plate is driven by the first cylinder to move downward, and at the same time, the second cylinder drives the connecting rod to drive the push block to move downward. The push block synchronously drives the two pairs of opposite telescopic sliders to move away from each other, so that the distance between the two pairs of opposite clamping strips is the largest and each clamping strip correspondingly moves to the outside of the workpiece to be carried; Next, the second cylinder drives the connecting rod to drive the pushing block to move upward until it no longer contacts the roller installed on the telescopic slider. During this process, each telescopic slider moves synchronously towards the sheet under the action of the elastic belt until the clamping strips facing each other clamp the sheet; During the above process, the up and down movement of the pushing block and the tensioning and contraction of the elastic belt are used to synchronously drive the telescopic sliders facing each other to move closer or farther away. The setting of the guide rod and the guide sleeve ensures the consistency of the moving block driving the telescopic slider during long-term reciprocating motion, avoiding the deviation of the position of the telescopic slider. Thus, the clamping strips installed on the telescopic slider can synchronously center and clamp and release the sheet, and ensure the stability and consistency of the surface contact between the clamping strip and the sheet. This not only facilitates the picking and placing of the sheet, but also ensures the stability and smoothness of the cooperation between the pushing block and the roller during long-term reciprocating contact, avoiding the situation of local jamming leading to clamping failure. It can also perform position calibration on the sheet in at least one direction while clamping, and can also achieve elastic clamping of the sheet and avoid damage caused by excessive unilateral force on the sheet; After the clamping of the sheet is achieved, the first cylinder drives the support plate to move upward, and then the external conveying mechanism drives the bracket to move to the next station and then releases the sheet; In addition, after the sheet is clamped, the angle of the horizontal substrate installed with the telescopic slider can be adjusted by the rotation of the motor, further improving the position accuracy and convenience of transporting the sheet.

[0041] When the above self-adaptive material transporting device for metal sheets is adopted, while realizing the picking, placing and transporting of the sheet, at the same time of elastically clamping the sheet, the up and down movement of the pushing block and the tensioning and contraction of the elastic belt are used to synchronously drive the telescopic sliders facing each other to achieve the centering calibration of the position of the sheet in the horizontal direction, ensuring the picking and placing accuracy of each sheet and the consistency of the position accuracy when transporting multiple sheets, and ensuring the stability and smoothness of the cooperation between the pushing block and the roller during long-term reciprocating contact, avoiding the situation of local jamming leading to clamping failure. The angle of the picked sheet can also be adjusted by the rotation of the horizontal substrate, further improving the position accuracy and convenience of transporting the sheet. Moreover, the setting of the guide rod and the guide sleeve ensures the consistency of the moving block driving the telescopic slider during long-term reciprocating motion, avoiding the deviation of the position of the telescopic slider, so as to ensure the stability and consistency of the surface contact between the clamping strip and the sheet when the clamping strip installed on the telescopic slider synchronously centers and clamps and releases the sheet.
