Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1 to 2, the present invention provides an AOI dust removing apparatus 100, which includes a sealed box 10, an anode dust collecting plate 20, a cathode discharging plate 30 and a power source 40. The positive pole of the power source 40 is communicated with the anode dust collecting plate 20, and the negative pole is communicated with the cathode discharge plate 30.

The seal box 10 is square, the bottom of the seal box is provided with an opening, and the bottoms of the two lateral surfaces which are symmetrical left and right are respectively provided with an inlet groove 11 and an outlet groove 12. The anode dust collecting plate 20 and the cathode discharge plate 30 are mounted on the front and rear symmetrical inner sides of the sealed box 10, wherein the anode dust collecting plate 20 is provided with a pulley 21, and the inner side of the sealed box 10 is correspondingly provided with a slide rail 13. The outer sides of the anode dust collecting plate 20 and the cathode discharge plate 30 are both sleeved with an insulating shell 50, and one side of the insulating shell 50 is in a mesh hollow design. The PCB enters the sealed box 10 from the inlet slot 11 for detection, and flows out from the outlet slot 12 for the next process, and the anode dust collecting plate 20 with the pulley 21 can scan and suck dust in the sealed box 10 to remove the dust in the sealed box 10 as much as possible. The insulating housing 50 wraps the anode dust collecting plate 20 and the cathode discharge plate 30, so that electric shock can be effectively avoided, and the safety of the dust removing device is enhanced.

The AOI dust removing device 100 further includes an ultrasonic vibration device (not shown). The ultrasonic vibration device is arranged below the seal box 10, and can perform ultrasonic vibration cleaning on the PCB. The dust with strong adhesion on the PCB can be oscillated and separated by the ultrasonic wave, and the energy of the ultrasonic wave can also oscillate and pulverize the large-particle dust into smaller-particle dust, so that the anode dust collecting plate 20 can adsorb the dust more easily.

The AOI dust removing device 100 further includes a dust removing brush 60 and a driving motor (not shown), wherein the dust removing brush 60 is designed in a roller shape. The dust removing brush 60 is fitted into the inlet slot 11 of the sealing box 10, and the driving motor is connected to the dust removing brush 60 to drive the dust removing brush 60 to rotate. The dust removing brush 60 may pre-sweep the PCB as it enters the sealing can 10 to isolate most of large particle dust on the PCB from the sealing can 10 in advance.

The AOI dust removal device 100 further comprises a cleaning partition plate 70, a strip-shaped through hole 14 penetrating through the inner side and the outer side is formed in the top of the seal box 10 correspondingly, and the cleaning partition plate 70 is arranged in the strip-shaped through hole 14 in a penetrating mode. The side of the seal box 10 close to the anode dust collecting plate 20 is designed to be removable. The outer side of the seal box 10 at the strip-shaped through hole 14 is provided with a lock catch 71, and the lock catch 71 can lock or release the cleaning partition plate 70 to control the lifting of the cleaning partition plate 70. The cleaning partition 70 can isolate a part of the space in the sealed case 10 for cleaning dust on the anode dust collecting plate 20 so that the sealed case 10 is not secondarily contaminated during the cleaning process.

When the utility model works, firstly, the power supply 40 is turned on to charge the anode dust collecting plate 20 and the cathode discharge plate 30, and simultaneously, the driving motor is started to drive the dust removing brush 60 to rotate. When the PCB enters the sealing box 10 from the inlet slot 11, the dust removing brush 60 first cleans the dust of the PCB in advance by rotating. When the PCB is transferred into the hermetic container 10, the ultrasonic vibration device is activated to further oscillate and detach the dust remaining on the PCB. Then the anode dust collecting plate 20 scans along the slide rail 13 in the seal box 10 to adsorb all the dust. And finally, after AOI detection is finished, the PCB flows out through the outlet groove 12 and enters the next working procedure. When the anode dust collecting plate 20 is excessively dusted and needs to be cleaned, the locking buckle 71 is opened to put down the cleaning partition plate 70, and then the sealing box 10 is opened at one side to clean the anode dust collecting plate 20. After cleaning, the sealing box 10 is closed, and the cleaning partition 70 is lifted and locked by the lock catch 71.

In summary, the AOI dust removal device 100 of the present invention has the following beneficial effects: by adopting the electrostatic dust collection principle, the anode dust collection plate 20 is used for scanning dust collection in the seal box 10, so that the interference of dust on AOI detection is effectively avoided; the integrated board and the discharge board are sleeved with the insulating shell 50, so that accidental electric shock can be prevented, and the safety of the device is greatly enhanced; the ultrasonic vibration device is used for vibrating and cleaning the PCB, so that dust with strong adhesion on the PCB is vibrated and separated, and dust particles are refined, so that the dust particles are easier to be adsorbed by the dust collecting plate; a dust removing brush 60 is arranged at the inlet of the seal box 10 to remove dust on the PCB, so that the dust removing effect is further improved; the cleaning partition 70 can temporarily isolate the dust collecting plate from the main body space of the seal box 10, preventing secondary pollution which may be caused to the AOI dust removing device 100 during shutdown cleaning; the utility model has strong practicability and stronger popularization significance.
