[0035] The accessory polishing system of the present application can realize automatic identification, positioning transportation and automatic overturning polishing of the parts to be polished through the linkage of the visual identification device 3, the conveying belt 1 and the machine hand mechanism 2. The tool changing device 4 is provided with a quick change disc, which can assist the machine hand to clamp or polish accessories of different models and different conditions. The dust removal device 5 can maximize the purification of metal dust generated in the polishing process. At the same time, the conveying line is connected with the cleaning device 6. After polishing, the accessories are directly cleaned, the polishing dust and dirt attached to the parts to be repaired are cleaned, and the subsequent operation process is facilitated.

[0036] The quick change disc, also known as tool quick change disc or gun changing disc, is an end-of-arm tooling (EOAT) device that allows robots to quickly and easily change different end-of-arm tools such as clamps, welding guns, machine hands, spray guns, suction cups, etc. to adapt to different production tasks. The machine hand mechanism 2 and the quick change disc are equipped with precise positioning pins and locking mechanisms to ensure accurate alignment and firm locking when connected.

[0037] As an optional embodiment, the dust removal device 5 includes a dust collection box 501, a ventilation duct 502, a dust suction pipe 503 and a plurality of bracket columns 504.

The bracket column 504 supports the ventilation duct 502, so that it is laid along the conveying belt 1 above the polishing station, continuously sucking away dust during the polishing operation, and keeping the station clean.

[0038] Because the structures and sizes of different types of fittings are different, the height position of the machine hand mechanism 2 clamping the fittings and turning and adjusting the fittings is different, and the polishing action is different. In order to ensure the effect of dust purification, the height of the dust suction pipe 503 needs to be adjusted according to the situation, and the dust suction pipe 503 should not hinder the polishing action of the machine hand mechanism 2 during the polishing operation. Therefore, as an optional embodiment, the dust suction pipe 503 is a telescopic pipe, and the dust removal device 5 further comprises a height adjusting mechanism 506, which is arranged on the bracket column 504 and connected to the lower end of the dust suction pipe 503, for adjusting the height of the lower end of the dust suction pipe 503.

The visual recognition device 3 can use a binocular camera, which is used to identify the type of the fitting first, control the machine hand mechanism 2 to replace the corresponding clamping tool according to the type of the fitting, then identify the rust or dirt position on the fitting, control the machine hand mechanism 2 to replace the corresponding polishing tool, and when the polishing of one surface is completed, the machine hand mechanism 2 turns and adjusts the fitting to identify and polish the next surface.

[0040] As an optional embodiment, a industrial control device 7 is further included, which is electrically connected with the conveying belt 1, the machine hand mechanism 2, the visual recognition device 3 and the dust removal device 5. The industrial control device 7 can use a PLC control system, which serves as a control center to ensure the cooperation of each device to complete the entire polishing process.

[0041] As an optional embodiment, the cleaning device 6 is provided with an audible and visual prompt component, which is electrically connected with the industrial control device 7. The industrial control device 7 can record the number of fittings currently conveyed to the cleaning device 6, and when the number reaches a preset number, sends a signal to the audible and visual prompt component, which is turned on and gives a prompt to remind the operator to manually check and adjust the fittings to be cleaned in the cleaning device 6. After the check is completed, the ultrasonic cleaning device 6 is manually turned on for cleaning. The cleaning device 6 can also be electrically connected with the industrial control device 7, and sends a signal to the industrial control device 7 after cleaning is completed, and the industrial control device 7 controls the audible and visual prompt component to be turned on to remind the operator to transfer the cleaned fittings.

[0042] As an optional embodiment, the conveying belt 1 is L-shaped, and two conveying belts 1 are vertically spliced to form the polishing production line. The cleaning device 6 is connected with the end of the conveying belt 1 to form the polishing production line. The accessory polishing system includes two polishing production lines, the two polishing production lines are symmetrical to each other, one dust collection box 501 is arranged between the two cleaning devices 6, and the dust collection box 501 is connected with the ventilation pipe 502 on the two polishing production lines. That is, the dust collection box 501 is taken as the middle axis, and two sets of polishing production lines are arranged on both sides of the dust collection box 501. The two sets of polishing production lines share one dust collection box 501. The machine hand mechanism 2 and the tool changing device 4 are arranged in the area between the two L-shaped conveying belts 1, and the layout is compact and the dynamic line is reasonable.

[0043] As an optional embodiment, the cleaning device 6 is an ultrasonic cleaner. The ultrasonic cleaner is lower than the conveying belt 1, and the accessory can directly fall into the cleaning tank of the ultrasonic cleaner from the conveying belt 1.

[0044] As an optional embodiment, the dust suction pipe 503 is a telescopic corrugated pipe, the lower end of the corrugated pipe is provided with a dust suction port 505 which is narrow at the top and wide at the bottom, and a fixed plate is arranged on the periphery of the dust suction port 505. The height adjusting mechanism 506 includes four electric push rods arranged in the vertical direction, one end of the four electric push rods is fixed on the bracket column 504, and the other end is connected to the four corners of the fixed plate respectively, and the corrugated pipe is located in the middle of the four electric push rods. The four electric push rods act in unison and are telescopic under the instruction of the industrial control equipment 7, so as to adjust the height of the fixed plate and the dust suction port 505.

[0045] Based on the above embodiment, the working process of the accessory polishing system is as follows: the accessory to be polished is transferred to the conveying belt 1, the conveying belt 1 conveys the accessory to be polished to the polishing station of the adaptive machine hand mechanism 2, the visual recognition device 3 assists the machine hand mechanism 2 to adjust the position of the accessory to be polished, the machine hand mechanism 2 changes the polishing tool on the tool changing device 4, and the polishing operation is performed, and the dust suction equipment works. The position of the dust suction port 505 is adjusted according to the model of the accessory to be polished and the polishing process. After the first polishing is completed, the machine hand mechanism 2 changes the turnover tool on the tool changing device 4, clamps the accessory to be polished and adjusts the position and posture of the accessory to be polished. The process of adjusting the position-polishing operation is repeated until all the positions to be polished are polished. Then the accessory to be polished is conveyed to the cleaning device 6 by the conveying belt 1. When the number of the polished accessories reaches a preset number, a signal is sent to prompt the operator to check and start the ultrasonic cleaning operation. After the cleaning operation is completed, the accessory is transferred to the next process position.
