[0026] Referring to Figures 1 to 2 , a 4-head linkage rotary lifting mounting mechanism is provided, which comprises a support seat 1, a connecting frame 2 in sliding connection with the support seat 1, four vacuum suction assemblies 3 fixed in parallel on the connecting frame 2, a servo motor 4 connected with and driving the four vacuum suction assemblies 3 to rotate through a transmission belt 9, and a lifting cylinder 5 driving the connecting frame 2 to lift.

[0027] At least two slide rails 11 extending along the height direction of the support seat 1 are fixed on the support seat 1, and the slide rails 11 are in sliding connection with the connecting frame 2.

[0028] The connecting frame 2 comprises a limiting plate 21 and a fixing frame 22 fixed below the limiting plate 21, wherein the servo motor 4 is fixed below the limiting plate 21, and the upper ends and lower ends of the four vacuum adsorption assemblies 3 are connected with the limiting plate 21 and the fixing frame 22 respectively.

[0029] Specifically, the limiting plate 21 is provided with four limiting through holes, one shaft hole and at least one telescopic hole, wherein the upper ends of the four vacuum adsorption assemblies 3 are fixed in the four limiting through holes through bearings respectively, and the upper and lower ends of the four vacuum adsorption assemblies 3 are exposed from the limiting through holes respectively; the servo motor 4 has an output shaft, which is exposed from the upper surface of the limiting plate 21 after passing through the shaft hole; the lifting cylinder 5 is fixed on the top of the support base 1, and the lifting cylinder 5 has at least one telescopic rod, which is connected with the fixing frame 22 after passing through the telescopic hole.

[0030] The vacuum adsorption assembly 3 comprises a vacuum suction head 33, a rotating shaft 31 and an extension shaft 32 connected between the vacuum suction head 33 and the rotating shaft 31, the rotating shaft 31 is connected with the limiting plate 21, and the extension shaft 32 is connected with the fixing frame 22. The fixing frame 22 has four fixing through holes, the extension shaft 32 is fixed in the fixing through holes through bearings, and the two ends of the extension shaft 32 are exposed from the fixing through holes.

[0031] The rotating shaft 31 is provided with a first airflow channel penetrating the rotating shaft 31 along the axial direction, and the extension shaft 32 is provided with a second airflow channel penetrating the extension shaft 32 along the axial direction, and the second airflow channel communicates with the first airflow channel and the vacuum suction head 33. The top of the rotating shaft 31 is connected with a rotating vacuum connector 6, the rotating vacuum connector 6 is connected with a vacuum pump through an air pipe, and the vacuum pump provides vacuum for the vacuum suction head 33 to enable the vacuum suction head 33 to adsorb the core sheet.

[0032] Referring to Figure 3 , the vacuum suction head 33 comprises a connecting cylinder 331, an adsorption head 333 and a hollow connecting rod 332 connected between the connecting cylinder 331 and the adsorption head 333, wherein the upper end of the connecting cylinder 331 is fixedly connected with the extension shaft 32, the adsorption head 333 is movably arranged in the hollow connecting rod 332 and the adsorption head 333 is exposed from the lower end of the hollow connecting rod 332, and the part of the adsorption head 333 exposed from the hollow connecting rod 332 is used for adsorbing the chip. The upper end of the hollow connecting rod 332 is fixedly connected with the lower end of the connecting cylinder 331.

In order to prevent gas from leaking between the adsorption head 333 and the hollow connecting rod 332 and between the connecting cylinder 331 and the hollow connecting rod 332, so that the vacuum suction head 33 cannot form a vacuum after being in contact with the chip, a sealing element is arranged between the adsorption head 333 and the hollow connecting rod 332 and between the connecting cylinder 331 and the hollow connecting rod 332, and the sealing element is a sealing gasket, a sealing ring or sealing glue.

Meanwhile, the limiting screw 335 can also prevent the adsorption head 333 from rotating relative to the hollow connecting rod 332, so that the adsorption head 333 rotates with the hollow connecting rod 332. A sealing gasket is arranged between the hollow connecting rod 332 and the limiting screw 335, so as to prevent gas from overflowing from the threaded hole.

[0036] The 4-head linkage rotary lifting and mounting mechanism further comprises one driving wheel 7 and four driven wheels 8. The driving wheel 7 is fixed on the output shaft of the servo motor 4, and the four driven wheels 8 are respectively fixed on the rotary shaft 31.

Preferably, the rotary shaft 31 is further sleeved with a lock nut 14 above the driven wheel 8, so as to prevent the driven wheel 8 from moving on the rotary shaft 31.
