The rotor supporting frame 2 comprises a square frame main body 201 and a square cavity 202 positioned in the middle of the frame main body 201, the cavity 202 can cover the outlet ends of all the paint joints 4, and the accurate butt joint of the butt joint module and all the paint joints can be realized conveniently. The two lateral sides of the frame main body 201 are respectively provided with a first lateral slideway 2011 positioned at the outer side and a second lateral slideway 2012 positioned at the inner side, and the two longitudinal sides are respectively provided with a first longitudinal slideway 2013 positioned at the outer side and a second longitudinal slideway 2014 positioned at the inner side. Three sets of positioning holes are respectively provided in the second transverse slideway 2012 and the second longitudinal slideway 2014, each set of positioning holes comprises a positioning pin hole 2031 and a pressure relief hole 2032, a pneumatic valve 204 is arranged in each positioning pin hole 2031, and a one-way valve is arranged in each pressure relief hole 2032. The frame main body 201 has a first rodless cylinder 2051 disposed inside one lateral side and a second rodless cylinder 2052 disposed inside one longitudinal side, and both ends of the first rodless cylinder 2051 and the second rodless cylinder 2052 are provided with an air inlet joint 2061 and an air outlet joint 2062. The outlet fitting 2062 is in communication with the plurality of pressure relief holes 2032 via an air line.
Referring to fig. 5, the docking module 3 is slidably mounted on the mover supporting frame 2 through a longitudinal bracket 501 and a transverse bracket 502. The two ends of the longitudinal bracket 501 are respectively installed in the first transverse slideway 2011 and the second transverse slideway 2012 on the same side, one end is connected with the piston of the first rodless cylinder 2051 to serve as a driving end, the other end is served as a driven end, and the longitudinal bracket 501 drives the docking module 3 to realize transverse movement (to be defined as movement along the X-axis direction) under the driving of the first rodless cylinder 2051 and the assistance of the two transverse slideways. The two ends of the transverse bracket 502 are respectively installed in a first longitudinal slideway 2013 and a second longitudinal slideway 2014 on the same side, one end is connected with a piston of a second rodless cylinder 2052 to serve as a driving end, the other end serves as a driven end, and the docking module 3 is driven to move longitudinally (defined as moving along the Y-axis direction) towards the bracket 502 by the driving of the second rodless cylinder 2052 and the assistance of the two longitudinal slideways. The X coordinate and the Y coordinate are arranged on the forming points of any shape in the plane, and the accurate butt joint of the butt joint module 3 and different paint joints 4 is realized by the structure.
During movement of the docking module 3, it is necessary to stop at a designated location and dock with the paint adapter 4. In order to ensure the accuracy of the stop position, the invention innovatively provides a mechanical closed-loop structure, which comprises the following specific steps: the two ends of the longitudinal support 501 and the two ends of the transverse support 502 are respectively provided with positioning blocks through spring pressure equalizing, and each positioning block is provided with a positioning pin and a pressure relief pin, and the positioning pins and the pressure relief pins have height differences.

In the normal moving process of the docking module 3, since the pneumatic valve 204 is not inflated, the positioning pin holes in the second transverse slideway and the second longitudinal slideway are in a closed state, the positioning pin can only slide along the slideway, and the pressure release pin is not in contact with the slideway. When the docking module 3 needs to stop at a designated position, the pneumatic valve 204 is opened by filling gas, the positioning pin hole is opened, the positioning pin is pressed downwards to be inserted into the positioning pin hole 2031 for positioning under the action of the spring, then the pressure release pin is inserted into the pressure release hole 2032, the one-way valve is jacked up, and at the moment, the gas which enters the rodless cylinder from the gas inlet joint 2061 and is used for acting is discharged from the pressure release hole 2032 after passing through the gas outlet joint 2062 and the gas pipe, and the rodless cylinder stops acting, so that the precise stop at the designated position is realized. Compared with the traditional electric signal control positioning, the mechanical closed-loop structure provided by the invention uses compressed air as power, so that not only can the energy consumption be saved, but also the positioning and control errors caused by electric signal delay can be effectively avoided. When the docking module 3 needs to move again, the pneumatic valve 204 is closed by stopping filling gas, the positioning pin is ejected out of the positioning pin hole, meanwhile, the pressure release pin is pulled out of the pressure release hole, and the cylinder starts to act to drive the docking module to move.
As a further improvement of the present invention, a rod cylinder may be used instead of a rodless cylinder, and the present invention is not limited to the type of cylinder.
As a further improvement of the present invention, since the stroke end of the first rodless cylinder 2051 and the stroke end of the second rodless cylinder 2052 are located at one corner of the square frame body 201, the present invention provides only one gas inlet joint 2061 and one gas outlet joint 2062 at the corner to simultaneously control two rodless cylinders.

The novel planar color-changing valve according to claim 4, wherein the rotor (302) is hollow along the axial direction, a cleaning channel (3022), a sewage draining channel (3023) and an end surface cleaning channel (3024) are processed in the rotor, and a plurality of vortex holes (3025) which are distributed along the axial direction are processed in the inner wall of the rotor; the end face cleaning channel (3024) and the vortex holes (3025) are communicated with the cleaning channel (3022); the end surface cleaning channels (3024) are obliquely arranged and are inclined to the butt joint end surfaces (3021) of the movers (302);
an inlet of the sewage drainage channel is positioned on a step surface at a butt joint end surface (3021) of the rotor (302); the inlet of the cleaning channel and the outlet of the sewage draining channel are both positioned on the other end face of the rotor (302).
