[0024] In addition, because the assembled wall panel group of the present invention adopts sleeve fitting and self-retractable snap-fitting fixed assembly, when measuring the gap width of the vertical light trough during the displacement of the wall panel during assembly, it is very difficult to push the wall panel by hand, and it is difficult to control accurately. Therefore, the present invention also provides a measuring set equipment, in which the horizontal adjustment mechanism built into the horizontal moving vehicle facilitates the vertical placement of the suction plate distance adjustment component and the width measurement component, so that the width measurement component will not tilt when sensing and measuring the width change of the vertical light trough in real time, thereby improving the width measurement accuracy. The suction plate distance adjustment component has functions such as buffering, pressure sensing, vacuum suction, and horizontal transverse movement. The buffering, pressure sensing, and vacuum suction can be used to coordinately press the wall panel with just the right force vertically and vacuum adsorb it, which can prevent problems such as damage to the wall panel due to excessive force and weakening of the adsorption performance due to insufficient force. The horizontal transverse movement function can realize slow horizontal displacement of the wall panel, so that the self-retractable adaption of the arc-shaped bayonet and the two sets of clips can operate more smoothly under the horizontal lateral force of the wall panel.

[0048] Working principle:

[0049] During assembly, first, the two support structure groups 3 need to be fixed vertically on the wall according to the width of the wall panel 2. The width of the vertical light trough to be set needs to be reserved. At this time, the left end support structure group 3 has a set of card core parts 32, and the right end support structure group 3 first takes out the card core parts 32. Then, the wall panel 2 is placed vertically between the two support base plates 313, and the wall panel 2 is placed to the right and manually pushed to the left so that the card core part 32 on the left end is engaged with the gap limiting card seat 22 on the left end. Then, the right end is fixed. A supporting structure group 3 at the end is equipped with a card core piece 32, so that the card core piece 32 at the right end and the gap limiting card seat 22 at the right end are in a self-expanding and engaging state, so that the two gap limiting card seats 22 at the left and right ends of the wall panel 2 will respectively fit with the two card core pieces 32, and the first card piece 331 and the second card piece 332 will automatically expand and contract and fit with the arc-shaped bayonet 26 to automatically fix the wall panel 2 between the two supporting structure groups 3, and then the measuring set equipment 5 is used to absorb and translate to the left. It should be noted that, as shown in the attached Figure 1 As shown, since the wall panel 2 at the right end is placed to the right and manually pushed to the left, the gap width between the two wall panels 2 is too large at this time, and the wall panel 2 on the right side needs to be translated to the left. However, the first clamp 331, the second clamp 332 and the arc-shaped bayonet 26 have formed a snap fit, and it is very difficult to use manual translation operation again, and lateral force cannot be achieved. In addition, it is difficult to control the width of the vertical lamp trough by manual push. Therefore, it is necessary to use the measuring set equipment 5 of the present invention to adsorb the right end wall panel 2 for left translation operation.

[0050] When the measuring set 5 is used, the measuring set 5 is first moved horizontally to the front between the two wall panels 2, and the built-in horizontal adjustment mechanism on the horizontal moving vehicle 51 is used to adjust the horizontal moving vehicle 51 so that the horizontal moving vehicle 51 is in a horizontal state. Then, the slider 533 on the width measuring component 53 slides horizontally on the cross rail 532, so that the optical sensor 534 is moved to the front of the vertical light trough for width sensing measurement. Then, the telescopic device 523 on the suction plate distance adjustment component 52 is extended, so that the various suction cups 5247 on the suction cup buffer seat 524 are pressed against the surface of the right end wall panel 2 according to the vertical interval. During the pressing process, the buffer seat will buffer, so that the pressure sensor 5245 can sense the pressing force of each suction cup 5247 on the wall panel 2. When the pressure sensor 5245 senses that the pressure reaches the limit value, the extension of the telescopic device 523 stops, and the vacuum pump 54 is started, so that each suction cup 5247 adsorbs the surface of the wall panel 2, so as to ensure that each suction cup 5247 is pressed against the wall panel 2. The pressure and adsorption on the surface are just right to prevent the wall panel 2 from being damaged by excessive force and the adsorption performance from being weakened by too little force. Then, the motor 526 is started, and the drag block is slowly moved to the left in the slide seat through the screw rod, pulling the adsorbed right end wall panel 2 to slowly move horizontally to the left. In this process, the arc-shaped bayonet 26 on the two gap-limited card seat 22 will automatically retract and engage with the two corresponding first card members 331 and second card members 332. When the optical sensor 534 senses and measures the vertical light trough When the width reaches the required value, the suction plate distance adjustment component 52 completes the operation. When all the assembled wall panel groups 1 are assembled, the vertical light troughs between the two adjacent wall panel parts 2 are consistent in width. Then install the light source strip 34 in the light source strip groove 315 and connect the lines in series. Because the wall panel part 2 is installed by hanging, the line can be discharged to the rear side of the wall panel part 2. Finally, directly engage the gap cover strip 4 on the outer side of the vertical light trough, and engage and fix it through the cylindrical clamp head 43 and the cover strip bayonet 27.

[0051] When the assembled wall panel group 1 is in use, the wall panel parts 2 are suspended by snap-fitting and do not come into contact with the wall, so they will not be damaged by factors such as alkali corrosion and moisture on the wall. In addition, when the wall panel parts 2 are used for a long time, when they are expanded and contracted due to temperature changes, the two sets of clips in the arc-shaped bayonet 26 will automatically expand and contract to adapt, preventing the wall panel parts 2 from being deformed and cracked due to hard pulling when expanding and contracting, and the vertical light trough can also play the role of expansion joints, and the gap cover strips 4 are fixed by snap-fitting, and the gap cover strips 4 will not be squeezed and cracked due to slight changes in the width of the vertical light trough. In addition, the light source strips 34 are illuminated in the vertical light trough. Since the gap cover strips 4 are made of plastic, they can transmit light outward, which can enhance the overall ornamental value of the assembled wall panel group 1.

[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
