Description

Technical Field

[0001] The present invention relates to the field of house decoration, in particular to a silo loading system and a screw installation robot. Background Art

[0002] The traditional installation process for expansion bolts involves drilling a hole, inserting the bolt, and finally tightening the nut. While drilling and inserting the bolt are relatively easy, tightening the nut is difficult to automate using traditional power tools due to the length of the lead screw. Therefore, automated tightening of expansion bolts has become a crucial step in the automated installation of lead screws for home renovations, with an automatic loading system completing the process.

[0003] During home renovations, a large number of expansion bolts and screw rods need to be installed on roofs. Manual installation is dangerous, poses health risks to workers, and is inefficient. With rising labor costs and the increasing difficulty of finding workers, automated installation is urgently needed. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention proposes a silo loading system, which can store a certain number of expansion bolt screw rods, and can send the expansion bolt screw rods forward through the screw rod slide, slide out of the silo outlet and enter the nut tightening device.

[0005] The technical problem to be solved by the present invention is specifically achieved by adopting the following technical solutions:

[0006] A silo feeding system includes: a silo that can store a certain number of expansion bolt screws; a pushing assembly that can push the expansion bolt screws along a slide to a discharge port; a feeding blocking assembly that can block the expansion bolt screws in the silo at the silo port and push the expansion bolt screws into a nut tightening device for feeding when feeding is required; a silo sensor assembly that can determine whether there is material in the silo; and a silo bracket for fixing the silo.

[0007] The silo loading system includes a silo, which also includes left and right main boards, a rear cross column, and a front U-shaped plate.

[0066] The comprehensive analysis of the system is as follows:

[0067] According to the specific situation of the screw installation at the top of the building, the installation steps are divided into five stages: the stage where the smart car arrives at the installation position, the stage where the vertical lifting part of the smart car rises to the position, the material picking stage, the installation stage and the return stage.

[0068] like Figure 7 As shown, when the silo loading system and the screw installation robot 600 are in the stage of the intelligent vehicle arriving at the installation position, the intelligent walking part 401 moves to the screw installation position under the guidance of the control system and the positioning system.

[0069] When the silo loading system and the screw installation robot 600 are in the stage where the vertical lifting part 402 of the smart car rises to a position fixed from the installation surface.

[0070] like Figure 1 、 Figure 4 、 Figure 7 As shown, when the silo feeding system and the screw installation robot 600 are in the material picking stage, the nut tightening device 100 runs to the discharge port 316 of the silo feeding system 300 to dock and prepare to receive the material; the baffle 334 of the feeding blocking assembly 330 retracts, the silo outlet 316 opens, and the pushing assembly 320 moves forward to push an expansion bolt 317 out of the nut slide 315, the baffle 334 extends, and the material-moving boss 338 continues to push the expansion bolt 317 forward and then returns to the initial position, blocking the expansion bolt 317 in the nut slide 315 from sliding out; at this time, the nut tightening device 100 receives the expansion bolt 317 to the rotation center, and detects whether the expansion bolt 317 is in place. If it is in place, the loading stage is completed.

[0071] like Figure 7 As shown, when the silo loading system and the screw installation robot 600 are in the installation stage, the vertical linear motion component 210 rises vertically for a certain distance, and the transverse linear motion component 220 rises to a certain distance at the same time; after rising to the position, the nut tightening device 100 moves to the installation hole position on the transverse linear motion component 220, and the nut tightening motion plate assembly 230 can make the nut tightening device 100 rise vertically to insert the expansion bolt 317 into the installation hole, and automatically determine whether it is inserted into the position; after the expansion bolt 317 is inserted into the installation hole, the nut tightening device 100 starts to tighten the nut of the expansion bolt 317 until it explodes, and detects whether it is the exit position. If it is the exit position, the expansion bolt 317 exits the nut tightening device 100, the nut tightening motion plate assembly 230 returns to the initial position, the vertical linear motion assembly 210 drops to the initial position, and the installation stage ends.

[0072] like Figure 7As shown, when the silo loading system and the screw installation robot 600 are in the return stage, the vertical lifting part 402 of the smart car descends to the initial position, and the nut tightening device 100 returns to the initial position, and an installation process is completed.
