Magnets are provided on both the pressure bar and the support bars, and the pressure bar and the support bars are magnetically connected through the magnets. A positioning module is also provided between the pressure bar and the support bars. Wherein, when the material is placed on the base, the pressure bar adheres to the support bar through the magnet to clamp the material.

[0026] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0027] Combined with Figure 1 , a kind of SMT material tray placing rack of the present invention includes a placing rack mechanism 1. A transfer mechanism 2 for transfer and transportation is fixedly arranged on one side of the placing rack mechanism 1. Two groups of tray stacking mechanisms 3 are rotatably connected to both sides of the placing rack mechanism 1. The placing rack mechanism 1 includes a fixed rack 11, a support rack 12 connected inside the fixed rack 11. A driving cylinder 13 is connected to the upper end of the support rack 12.

Circular grooves 161 are opened at the four corners of the SMT tray 16, and the upper end is provided with a top frame 163. The tray stacking mechanism 3 includes tray components 34 arranged on both sides of the SMT tray 16. The tray component 34 includes a rotatable L-shaped frame 343. The L-shaped frame 343 rotates and aligns with the circular groove 161 for clamping the SMT tray 16 and supporting the top frame 163.

[0028] Specifically, multiple groups of SMT trays 16 are stacked. The L-shaped frame 343 rotates to be engaged in the circular groove 161, which can support the top frame 163 to realize the positioning and fixing of the SMT tray 16. The fixing frame 11 and the supporting frame 12 play a supporting role. The driving cylinder 13 drives the frame 14 to lift and lower, and the lowest point of the lifting and lowering of the frame 14 is lower than the transfer height of the transfer mechanism 2. The driving cylinder 13 drives the frame 14 to rise, which can support the bottom of the SMT tray 16 engaged by the L-shaped frame 343. At this time, the L-shaped frame 343 is retracted, the driving cylinder 13 drives the frame 14 to descend by the height of one SMT tray 16, then the L-shaped frame 343 is rotated to support the second-layer SMT tray 16, and the bottommost SMT tray 16 can follow the frame 14 to descend until it is placed on the transfer mechanism 2 to complete the transfer. This is the step of single transfer of the stacked SMT trays 16. Conversely, the stacking of a single SMT tray 16 can be realized. The automatic stacking, sorting and transfer of the SMT trays 16 in this structure have high picking efficiency, and the engagement setting of the L-shaped frame 343 and the circular groove 161 realizes synchronous positioning during the transfer of the SMT tray 16.
