Therefore, strict quality inspection of the welds is essential after welding is completed.

The outer shell 1 is an integral structural frame, the inner cavity 2 accommodates and supports internal components, and the inlet 3 is the workpiece inlet.

[0042] According to an optional embodiment of the present invention, the drying mechanism further includes two heat collectors 19 and two force plates 24. The heat collectors 19 are slidably connected to the inner wall of the inner cavity 2. The heat collectors 19 are connected to the inner wall of the inner cavity 2 through an elastic element 20.

[0053] A quality inspection method for welded steel structure installation, comprising the following steps, utilizes a quality inspection device for welded steel structure installation to inspect the welded steel structure workpiece:

[0054] The workpiece is placed into the inner cavity 2 through the inlet 3. One end of the workpiece is clamped by one of the clamping mechanisms on one of the transmission chain devices 4, and the workpiece is clamped by one of the clamping mechanisms on the other transmission chain device 4. This achieves the clamping of two or more workpieces. The two transmission chain devices 4 drive the workpiece to move. The cleaning mechanism cleans the surface of the workpiece to remove contaminants. The drying mechanism dries the surface of the workpiece to remove moisture. The welding strength testing mechanism taps the workpiece to test its welding strength. The flaw detection mechanism performs flaw detection on the workpiece.

[0055] Implementation process:

[0056] The welded and installed plate-shaped workpiece is placed into the inner cavity 2 through the inlet 3. One end of the workpiece is clamped by one of the electric grippers 7 on one of the transmission chain devices 4, and one electromagnet 61 is pressed against the workpiece. The workpiece is clamped by one of the electric grippers 7 on another transmission chain device 4, and another electromagnet 61 is pressed against the workpiece. This is how to clamp two or more workpieces. The two transmission chain devices 4 drive the workpiece to move to the left. After the workpiece moves a certain distance to the left, the two transmission chain devices 4 stop for a period of time to allow each mechanism to process the workpiece. The placement angle of the workpiece can be adjusted according to the actual situation.

[0057] There is a workpiece to be cleaned below the nozzle 12, a workpiece to be dried below the collector 19 above, a workpiece to be struck below the striking part 33, and a workpiece to be inspected below the flaw detection fluid injector 36.

[0058] When the pump body 10, motor 13, and heating device 21 are turned on, the impeller inside the pump body 10 rotates at high speed to generate centrifugal force, which draws the cleaning fluid from one of the liquid tanks 8 and sprays it from the nozzle 12 on the outlet pipe 11 onto the surface of the workpiece to be cleaned. The cleaning fluid will flow along the surface of the workpiece to be cleaned, thereby removing impurities from the welded joints of the workpiece to be cleaned, so as to facilitate subsequent inspection steps. The cleaning fluid will fall into another empty liquid tank 8 for recycling.

[0059] Motor 13 drives gear 2 14 to rotate, and gear 2 14 drives gear 3 16 to rotate. Since the outer diameter of gear 3 16 is larger than that of gear 2 14, gear 3 16 will rotate at a slower speed, thereby driving worm 15, worm wheel 18, and rotating blade 17 to rotate. The heating element of heating device 21 heats up, and the wind generated by the rotation of rotating blade 17 blows the heat from the heating element of heating device 21 to the two heat collection chambers 25 and the workpiece to be dried, thereby drying the cleaning liquid on the workpiece. The heat collection plates 23 in the heat collection chamber 25 can collect heat over a large area and transfer it to the thermal expansion member 22. The thermal expansion member 22 expands and elongates due to heat, thereby pushing the two heat collection plates 23 closer to each other, so that the two heat collectors 19 come into contact. The notch 26 can accommodate the workpiece. In this way, the heat is concentrated, and the two heat collection chambers 25 form a drying chamber, which dries the workpiece faster, improves drying efficiency and drying quality, saves energy, and improves detection efficiency. After drying is complete, the heating device 21 stops heating, and the cold air from the rotating blade 17 causes the heat collection plate 23 and the thermal expansion member 22 to cool down rapidly. The thermal expansion member 22 cools down and shortens, so that the two heat collectors 19 move away from each other to facilitate the movement of the workpiece.

[0060] After the worm gear 15 is reduced by the reducer 27, it drives the eccentric bar 28 and the pressure cylinder 30 to rotate. When the pressure cylinder 30 lifts the force plate 29, the striking part 33 will overcome the elastic force of the second elastic element 32 and move upward along the L-shaped plate 31. After the pressure cylinder 30 is separated from the force plate 29, the striking part 33 strikes the workpiece to be struck under its own weight and the elastic force of the second elastic element 32. The pressure cylinder 30 rotates again until it abuts against the bottom wall of the force plate 29 and then lifts the force plate 29 again. In this way, the striking part 33 performs multiple strike tests on the workpiece to be struck. The length of the eccentric bar 28 is adjustable. The length of the eccentric bar 28 is locked by the locking mechanism, thereby controlling the displacement of the striking part 33 and adjusting the striking force of the striking part 33.

[0061] The flaw detection fluid injector 36 sprays magnetic suspension fluid onto the surface of the workpiece to be inspected. The electromagnet 61 is turned on. Since the steel inside the workpiece is a ferromagnetic material, when the electromagnet 61 is energized, a strong magnetic field is formed on the surface of the workpiece. The tiny ferromagnetic particles contained in the magnetic suspension fluid are attracted to the crack under the action of the leakage magnetic field, and gather along the crack outline to form a visible magnetic mark. The image acquisition device 37 acquires an image of the surface of the workpiece to be inspected, so that the user can view and judge whether there is a crack in the workpiece on the terminal device, so as to judge whether the welding quality of the workpiece is qualified.

[0062] When the transmission chain device 4 moves the workpiece to be inspected to the left, one of the connecting seats 5 pushes the driven plate 35 to move to the left against the elastic force of the elastic element 38. This causes the flaw detection liquid sprayer 36 and the image acquisition device 37 to move to the left along with the connecting seat 5. The flaw detection liquid sprayer 36 remains above the workpiece to be inspected on the connecting seat 5. After the gear 6 and rack 34 on the connecting seat 5 mesh, the rack 34 will cause the gear 6 to rotate, thereby turning the workpiece to be inspected over so that the back side of the workpiece can be inspected. The inspection of the back side of the workpiece is also carried out by spraying magnetic suspension liquid onto the surface of the workpiece by the flaw detection liquid sprayer 36, which will not be described again here. When the transmission chain moves the connecting seat 5 to the bottom of the transmission chain device 4, the connecting seat 5 releases its abutment against the driven plate 35. The connecting seat 5 moves to the right and resets under the elastic force of the elastic element 38 so that the front and back sides of the next workpiece to be inspected can be inspected.

[0063] When the connecting seat 5 moves to the bottom of the transmission chain device 4, the electric gripper 7 releases the workpiece, allowing it to fall into the storage box 39 for collection.

[0064] The beneficial effects of this invention are:

[0065] This device integrates five major mechanism modules: clamping, cleaning, drying, welding strength detection and flaw detection. It is arranged in a modular integrated manner on the inner wall of the inner cavity 2, which effectively improves the detection efficiency and automation level, and reduces manual operation time and error rate.

[0066] The transmission chain device 4 drives the connecting seat 5 and the electric gripper 7 to clamp the workpiece through the transmission chain, ensuring the stability of the workpiece during movement and inspection, and improving the repeatability and reliability of the inspection.

[0067] The cleaning mechanism uses the pump body 10 to drive the liquid extraction pipe 9 and the liquid outlet pipe 11 to form a cleaning route. The cleaning liquid is evenly sprayed onto the surface of the workpiece through the nozzle 12 to achieve efficient cleaning of the weld area and ensure the accuracy of subsequent flaw detection.

[0068] The motor 13 in the drying mechanism drives gear 14, gear 16, worm 15, worm wheel 18 and rotating blade 17 to achieve hot air circulation drying; together with the heating device 21 and the heat collector 19, a local hot air chamber is formed, which improves drying efficiency and saves energy.

[0069] The thermal expansion element 22 and the heat collection plate 23 work together to form an adjustable clamping heat collection structure with the elastic element 20. The spacing of the heat collector 19 can be automatically adjusted according to the drying process, so that the workpiece can be heated and dried quickly, and the continuity of work can be improved.

[0070] The rotating blade 17 can also achieve rapid cooling to cause the thermal expansion component 22 to contract, and separate the two collectors 19 to facilitate the movement of the workpiece;

[0071] The welding strength testing mechanism uses a worm gear 15 to drive a reducer 27, an eccentric bar 28, a pressure cylinder 30, and a striking component 33 to achieve continuous hammering testing of the workpiece. The T-shaped striking component 33, combined with the L-shaped plate 31 and the elastic component 32, prevents the contact area from being too small during hammering, which would cause excessive pressure and damage to the workpiece. This is superior to manual hammering.

[0072] The flaw detection fluid injector 36 and the image acquisition device 37 in the flaw detection mechanism are arranged on the driven plate 35. Combined with the rack 34 and gear 6, the workpiece is flipped and moved synchronously for flaw detection, ensuring that no defects on both sides are missed.

[0073] The image acquisition device 37 combines the magnetic particle inspection principle with the electromagnet 61 to form a visual crack recognition path, allowing users to remotely identify defects on the terminal and improve the level of intelligent detection.

[0074] After the inspection is completed, the workpiece can be moved to the bottom of the device via the transmission chain device 4, and automatically released into the storage box 39 by the electric gripper 7, realizing a closed-loop operation of workpiece collection after inspection, which is convenient for subsequent processing.

[0075] The entire device has a compact structure, with continuous and seamless cleaning, drying, and testing steps. It features precise cycle time, a reasonable layout, and utilizes a PCL control system to control the coordinated operation of various electrical components. It is suitable for the automation transformation of industrial production lines and has good engineering application prospects and promotional value.

[0076] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
