[0033] Working principle: First, after the robot body 1 moves to the designated position, the dual-axis motor 31 is started, and the dual-axis motor 31 drives the rotating shafts at both ends to rotate. The bevel gear connected to one end of the rotating shaft is meshed with the surrounding column 33, and the surrounding column 33 is driven to rotate during rotation. The rotation of the surrounding column 33 drives the adjacent display frame 4 to rotate, and the rotation action can drive the two display frames 4 to adjust their angles. When the display frame 4 rotates to the top of the support frame 21, the support frame 21 can support the bottom of the display frame 4, and the personnel can manually place the products to be displayed on the lifting platform 411, and then drive the surrounding column 33 to drive the display frame 4 to rotate to the bottom of the projector 61; Secondly, by starting the air pump 5, the gas is sucked from the air inlet end through the power output of the air pump 5, and then transported to the pneumatic push rod 413 connected to the hose through multiple hoses, and the pneumatic push rod 413 pushes the acrylic plate 42 to move to the top. At this time, the spring pushes the telescopic rod 44 and the positioning block 45 to contact the acrylic plate 42. After the acrylic plate 42 is lifted and separated from the plug-in slot, the positioning block 45 pushes the acrylic plate 42 to tilt toward one side of the projector 61. After tilting, one end of the multiple acrylic plates 42 all contact with the rectangular frame set at the bottom of the projector 61. Finally, the screen at the bottom of the projector 61 is started to project light onto the multiple acrylic plates 42, thus realizing the style of a three-dimensional projection product, and performing a three-dimensional rotating display to visitors, thereby displaying product information more intuitively and three-dimensionally; It should be noted that when one end of the multiple acrylic plates 42 is tilted and contacts the rectangular frame, the pneumatic push rod 413 can simultaneously drive the side support rod 414 to be raised and lowered synchronously. At this time, the side support rod 414 pulls the steel wire rope, and cooperates with the guide of the guide wheel 7 to pull the lifting platform 411 to be lifted. Secondly, when the side support rod 414 is lifted to the top, the tension on the steel wire rope is relaxed, and the lifting platform 411 moves to the bottom with the tension of the spring, driving the product to move to the bottom and into the display frame 4; At this time, while observing the style of the product inside the display frame 4 through the tempered glass on the front side of the display frame 4, the personnel can cooperate with the three-dimensional model displayed on the acrylic plate 42, which can more efficiently ensure that the personnel understand the product information; when the acrylic plate 42 is displayed through the three-dimensional projection model, the product is lowered into the display frame 4 along with the lifting platform 411, which can effectively avoid the product being located at the bottom of the acrylic plate 42 to block the display effect of the three-dimensional projection model.
