[0024] See also Figure 1 、 Figure 2The first workpiece 14 is a part with an inner hole such as a nut or a sleeve, and the second workpiece 15 is a plate-shaped part such as a PCB board; the fixing portion 31 of the expansion member 3 is a columnar structure, and the fixing portion 31 is fixedly mounted on the bracket 2, and the expanding portion 32 of the expansion member 3 can extend in a direction away from the central axis of the fixing portion 31 to tighten the inner hole of the first workpiece 14, so as to realize the picking up of the first workpiece 14. The bracket 2 is provided with a driving source for controlling the movement of the pressing plate 4 between the support plate 1 and the bracket 2. The driving source can be a driving cylinder or a screw module. The pressing plate 4 is provided with a shaft sleeve 5 on the side close to the support plate 1, and the shaft sleeve 5 is sleeved on the outside of the expansion member 3 and can pass through the support plate 1. The driving source drives the pressing plate 4 to approach the support plate 1, so that the shaft sleeve 5 that moves synchronously with the support plate 1 can move relative to the expansion member 3 to squeeze the expanding portion 32 of the expansion member 3, so that the expanding portion 32 of the expansion member 3 no longer tightens the inner hole of the first workpiece 14, thereby realizing the withdrawal of the first workpiece 14.

[0025] See also Figure 1 The second surface of the support plate 1 is also provided with a clamping structure for clamping the plate-shaped second workpiece 15. By clamping the plate-shaped second workpiece 15 through the clamping structure, the clamping range of the present application for the types of parts can be improved.

[0026] Specifically, when the first workpiece 14 and the second workpiece 15 are transported at the same time, the second surface of the support plate 1 is first controlled to face the first workpiece 14 and the second workpiece 15, and then the support plate 1 is controlled to move downward so that the expanding portion 32 of the tightening member 3 restricted by the shaft sleeve 5 enters the first workpiece 14 and the second workpiece 15 is clamped by the clamping structure. The driving source is used to control the pressure plate 4 to move away from the support plate 1, and the shaft sleeve 5 moves with the support plate 1 to release the restriction on the expanding portion 32 of the tightening member 3, so that the expanding portion 32 of the tightening member 3 expands the inner hole of the first workpiece 14, thereby fixing the first workpiece 14; thereafter, the support plate 1 is transported to the workpiece to be installed At the module or workpiece where the first workpiece 14 and the second workpiece 15 are installed, the driving source is used to control the pressure plate 4 to move toward the support plate 1, and the sleeve 5 moves with the push plate 8 to form a contraction limit on the expansion portion 32 of the expansion member 3. The first workpiece 14 is no longer restricted and is placed in a predetermined position. At the same time, the clamping structure is controlled to release the clamping of the second workpiece 15 so that the second workpiece 15 is placed in a predetermined position; through this setting, the present application can realize the simultaneous transportation of different types of workpieces, effectively reducing the number of transportation times and transportation equipment caused by classification and batch transportation, effectively saving production costs, and improving the transportation efficiency of workpieces, which is practical.

[0027] In one or more embodiments, the expanding portion 32 is at least two groups of spring pieces evenly mounted on the ends of the fixing portion 31 and extending away from the central axis of the fixing portion 31 .

When the expansion portion 32 is not restricted by the sleeve 5, the expansion portion 32 is in an open state to expand the inner hole of the first workpiece 14. When the bearing portion is restricted by the sleeve 5, the expansion portion 32 is in a contracted state. At this time, the expansion portion 32 no longer presses against the inner hole of the first workpiece 14 to release the restriction on the first workpiece 14, and the first workpiece 14 can exit the expansion portion 32 of the tightening member 3. Through this arrangement, the first workpiece 14 can be quickly clamped while ensuring the stability of the clamping of the first workpiece 14.

[0029] In other possible embodiments, a rubber airbag is disposed in the expansion portion 32 composed of a plurality of spring sheets.

When the second workpiece 15 held by the clamping jaws 6 needs to be unloaded, the pressure plate 4 is driven toward the support plate 1 by the aforementioned drive source. The push plate 8, which moves synchronously with the pressure plate 4, can push the second workpiece 15 into the predetermined position of the mold, thereby unloading the second workpiece 15.
