[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] refer to Figures 1 to 4, On the one hand, the utility model provides a material frame lifting mechanism, comprising: a carrier plate 10, the carrier plate 10 has a relative top surface 101 and a bottom surface 102, the top surface 101 is used to carry the material frame 20, the material frame 20 is a material frame 20 for carrying wafers, usually a material frame 20 has a plurality of slots, each slot can hold a wafer, and a material frame 20 can hold multiple wafers; two clamping groups are arranged at intervals along the length direction Y of the carrier plate 10, each clamping group includes two clamping modules 30 arranged oppositely, the clamping module 30 includes a fixing block 31 and a locking strip 32, the fixing block 31 is arranged on the bottom surface 102 of the carrier plate 10, one end of the locking strip 32 is connected to the fixing block 31, and the other end of the locking strip 32 extends above the top surface 101 of the carrier plate 10, the carrier plate 1 0 has a first side and a second side arranged along the width direction X of the carrying plate 10. For each clamping group, two snap bars 32 are respectively located on the first side and the second side, and the distance between the two oppositely arranged snap bars 32 is adjustable. The snap bars 32 are used to clamp and fix the material frame 20. Specifically, when the material frame 20 is placed on the carrying plate 10, the four snap bars 32 of the two clamping groups are located around the material frame 20, and the distance between the two opposite snap bars 32 in each group is reduced. The four snap bars 32 stably fix the material frame 20 on the top surface 101 of the carrying plate 10; the driving assembly 40 and the connecting plate 50, the driving assembly 40 and the connecting plate 50 are connected, the carrying plate 10 is arranged on the connecting plate 50, and the driving assembly 40 is used to drive the connecting plate 50 to move along the thickness direction of the carrying plate 10.

[0028] The driving assembly 40 is driven by a servo motor to drive the carrying plate 10 to move, thereby driving the material frame 20 to rise, fall or move.

[0029] For further reference, Figure 3 The fixing block 31 has a limiting hole that passes through the fixing block 31 along the width direction X of the carrier plate 10; one end of the locking bar 32 has a connecting piece 322 that extends along the width direction X of the carrier plate 10.

The cylinder 90 is fixed to the bottom surface 102 of the carrier plate 10, and the free end 91 of the cylinder 90 is fixed to the locking bar 32. The cylinder 90 is used to drive the locking bar 32 to move along the width direction X of the carrier plate 10, thereby adjusting the distance between the two oppositely arranged locking bars 32.

[0032] Furthermore, the connecting plate 50 has a first surface 52 and a second surface 51 opposite to each other. The first surface 52 is connected to the driving assembly 40 . The supporting plate 10 is fixed on the second surface 51 , and the side surface of the supporting plate 10 faces the second surface 51 .

[0033] In some embodiments of the present invention, the thickness direction of the supporting plate 10 is the vertical direction, and the driving assembly 40 drives the connecting plate 50 , thereby driving the supporting plate 10 to move up and down in the vertical direction.

[0034] Furthermore, the material frame lifting mechanism includes at least two trapezoidal reinforcement plates 103, which are spaced apart along the length direction Y of the carrier plate 10 and arranged parallel to the angle formed by the carrier plate 10 and the connecting plate 50. One side of the trapezoidal reinforcement plate 103 is fixed to the bottom surface 102 of the carrier plate 10, and the other side of the trapezoidal reinforcement plate 103 is fixed to the second surface 51.

[0035] Furthermore, the top surface 101 of the carrier plate 10 has a groove 11, and the outer surface of the material frame 20 has a protrusion. When the material frame 20 is placed on the carrier plate 10, the protrusion cooperates with the groove 11 to retain the material frame 20 on the carrier plate 10.

[0039] The material frame lifting mechanism provided by the present invention places the material frame 20 on the top surface 101 of the carrier plate 10, and adjusts the distance between the two pairs of oppositely arranged snap bars 32 through the cylinder, and uses the snap bars 32 to clamp and fix the material frame 20.
