For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] Such as Figure 1 And Figure 2As shown in the figure, the lifting and transfer mechanism provided by the embodiment of the present utility model includes: a frame 001, a lifting drive device 002, an idle pulley 003, a chain 004, a lifting frame 005, and a lateral conveying device 006; the lifting frame 005 is slidably connected to the frame 001 in the z direction; the lifting drive device 002 is installed on the frame 001, and the idle pulley 003 is installed at the movable end of the lifting drive device 002; one end of the chain 004 is connected to the frame 001, and the other end of the chain 004 bypasses the idle pulley 003 and is connected to the lifting frame 005; the lateral conveying device 006 is installed on the lifting frame 005, and the lateral conveying device 006 is used to convey the transferred parts to move in the x direction, where the x direction is perpendicular to the z direction.

[0039] Specifically, the lifting drive device 002 can use a cylinder or a hydraulic cylinder to drive the idle pulley 003 to lift and lower by telescoping, or a servo motor can be used to drive the lead screw to rotate, and the lead screw is used in cooperation with a slider to drive the slider to lift and lower, and then drive the idle pulley 003 installed on the connected slider to lift and lower. The idle pulley 003 can rotate around an axis parallel to the x direction relative to the lifting drive device 002. When the lifting drive device 002 drives the idle pulley 003 to lift and lower, one end of the chain 004 connected to the lifting frame 005 will lift and lower with the change of the position height of the idle pulley 003. The lifting speed of the lifting frame 005 is twice that of the idle pulley 003, which improves the lifting drive efficiency. In addition, the lateral conveying device 006 can use devices such as a conveyor belt or an electric roller to drive the transferred parts on it to move in the x direction. The lifting and lateral movement are independent of each other and do not interfere with each other, which improves the structural compactness.

Among them, the limiting member 701 can be configured as a snap ring, and the snap ring can be fitted into one of a plurality of card slots arranged along the axial direction of the rod 007, or the limiting member 701 can be configured as a nut that is threadedly fitted to the rod 007. By adjusting the position of the limiting member 701, the initial height position of the lifting frame 005 can be adjusted, so as to realize the adjustment of the upper and lower limit positions of the lifting frame 005.

[0041] See Figure 1 and Figure 3 As shown in the figure, in an alternative embodiment, a buffer 008 is installed on the frame 001 and / or the lifting frame 005; when the position of the lifting frame 005 moves to the top working position and the bottom working position, the buffer 008 abuts against the frame 001.

[0042] In one embodiment, the frame 001 is installed with a buffer 008. When the position of the lifting frame 005 moves to the top position, the buffer 008 abuts against the upper end surface of the lifting frame 005, thereby achieving limiting and buffering at the upper limit position.

[0043] In another optional or combined embodiment, the lifting frame 005 is installed with a buffer 008 extending downward. When the lifting frame 005 moves to the bottom position, the buffer 008 abuts against the lower beam of the frame 001, thereby achieving limitation and buffering at the lower limit position.

The movable end of the telescopic cylinder 201 is connected to a mounting block, and the idler wheel 003 is rotatably connected to the mounting block.

[0045] In addition, to prevent the idler wheel 003 and the chain 004 from sliding relative to each other, the idler wheel 003 can be configured as a sprocket, and the sprocket can be matched with the chain 004. It is also possible to install multiple idler wheels 003 on the mounting block, each idler wheel 003 is matched with a chain 004, and the lifting frame 005 is pulled together by multiple chains 004, thereby reducing the load of a single chain 004.

[0050] In addition, a distance sensor 013 is installed at one end of the frame 001 in the x direction. The distance sensor 013 can be configured as a proximity sensor in the form of ultrasonic or electromagnetic, used to detect the distance between the sensor and the part to be transferred, and thus obtain the position of the part to be transferred.

When the part to be transferred is conveyed in place, the controller controls the positioning cylinder 014 to extend, so that the positioning pin 015 is inserted into the pin hole on the part to be transferred, thereby realizing the positioning of the part to be transferred.
