Description

Technical Field

[0001] The invention relates to the field of galvanizing devices, and in particular to an automatic discharging and positioning mechanism for a scaffolding crossbar. Background Art

[0002] Hot-dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is an effective way to prevent metal corrosion, mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts in a zinc solution melted at about 500°C, so that a zinc layer adheres to the surface of the steel components, thereby achieving the purpose of corrosion protection. Hot-dip galvanizing process: finished product pickling - water washing - adding auxiliary plating solution - drying - hanging plating - cooling - passivation - cleaning - polishing - hot-dip galvanizing is completed.

[0003] At present, in the galvanizing production line of scaffolding crossbars, the crossbars are basically in a disordered state in the transfer material frame, and the crossbars are hung manually during the hanging process. Since the crossbars need to be hot-dip galvanized in a specific position to ensure the best galvanizing effect, the use of workers to scrape materials greatly increases labor costs and reduces hanging efficiency. The labor intensity of employees is also high, which is prone to more mistakes and there are also considerable safety risks. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0019] Reference Figure 1 As shown, an embodiment of an automatic material discharging and positioning mechanism 2 for a scaffolding cross bar 18 of the present invention comprises a loading mechanism 1, a positioning mechanism 2 and a unloading mechanism 3, the loading mechanism 1 comprises symmetrically arranged transfer devices, moving rods 4 are arranged in the two transfer devices, the moving rods 4 are arranged with a first track 5, the first track 5 is arranged with a moving block 6, the moving block 6 is arranged with a motor 7, the motor 7 is arranged with a suction plate 8, and a material frame 9 is arranged below the suction plate 8; the positioning mechanism 2 and the unloading mechanism 3 are both arranged on a workbench 10, the workbench 10 is provided with a conveyor belt 11, the positioning mechanism 2 comprises a first material gate 12 and a second material gate 26, the first material gate 12 comprises a first limiting rod 13 and a visual recognition mechanism 14, the second material gate 26 comprises a rotating cylinder 15 and a second limiting rod 16.

[0020] The transfer device includes a support rod 17, a cross bar 18 is arranged on the support rod 17, a second track 19 is arranged on the opposite surface of the two cross bars 18, and the moving rod 4 is arranged in the second track 19.

[0021] When in use, first place the arranged scaffolding accessories in the material frame 9. At this time, the moving rod 4 can be moved above the material frame 9 by utilizing the characteristic that the moving rod 4 can move in the second track 19. The moving block 6 is adjusted again to adjust the suction plate 8 to a suitable position. At this time, the motor 7 is started, the suction plate 8 descends, and the product is sucked out. After the adsorption is completed, the suction plate 8 rises, and the position of the moving rod 4 is moved above the workbench 10 again. At this time, the motor 7 is started, the suction plate 8 descends, and the material is placed on the workbench 10. The suction plate 8 uses an electromagnet and can be powered off and demagnetized at any time.

[0022] Afterwards, the reducer drives the conveyor belt 11 to move and conveys the material to the first material gate 12. The first material gate 12 includes a first limit rod 13 and a visual recognition mechanism 14. The visual recognition mechanism 14 can be used to obtain the position information of the material at this time, and the first limit rod 13 can be used to limit the position of the material when it passes through the first material gate 12. For example, the height of the material is different when it is in different positions. The first limit rod 13 can be used to limit the material to the expected position, and then pass through the second material gate 26. At this time, the staff can obtain the state of the material at this time through the position information transmitted from the visual recognition mechanism 14. If it is not the expected position, the rotating cylinder 15 on the second material gate 26 is used to rotate the material to the expected position, and finally enter the unloading mechanism 3 for arrangement, waiting to be grabbed by the automatic device.

[0023] The unloading mechanism 3 includes a main positioning plate 24 and an auxiliary positioning plate 25. The length of the main positioning plate 24 is equal to the width of the workbench 10. The auxiliary positioning plate 25 is arranged on the main positioning plate 24 and can be moved by a moving device. The main positioning plate 24 can limit the material passing through the first material door 12 and the second material door 26 on the conveyor belt 11 to prevent it from falling off the workbench 10. The auxiliary positioning plate 25 can limit the vertical position of the material at this time. When it is necessary to take the material, the auxiliary positioning plate 25 is retracted. At this time, an automatic material taking device such as a robot can take the arranged material from the workbench 10 to realize a fully automated process.

[0024] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention.
