Example

[0023] like Figure 1 and 2 As shown, one embodiment of this application provides a dust removal and static electricity removal device, including:

[0024] The feeding conveyor line 1 is used for feeding and conveying product 8, and also includes an antistatic dust removal mechanism 2, which includes a housing 21, an upper negative pressure conveyor line 22, a lower antistatic dust removal module 23, and an upper antistatic dust removal module 24. The upper negative pressure conveyor line 22, the lower antistatic dust removal module 23, and the upper antistatic dust removal module 24 are housed inside the housing 21, extending into the housing 21 from the feed port and staggered vertically with the first end of the upper negative pressure conveyor line 22. The lower antistatic dust removal module 23 is located below the upper negative pressure conveyor line 22. The discharging conveyor line 3 is used for discharging and conveying product 8. One end of the discharging conveyor line 3 extends into the housing 21 from the discharge port and staggered vertically with the second end of the upper negative pressure conveyor line. The upper antistatic dust removal module 24 is located above the discharging conveyor line 3. A lower guide roller 4 is provided between the end of the feeding conveyor line 1 extending into the housing 21 and the lower static electricity removal and dust removal module 23. The product 8 moves from the feeding conveyor line 1 to above the lower static electricity removal and dust removal module 23 via the lower guide roller 4 without contacting the lower static electricity removal and dust removal module 23. The end of the discharging conveyor line 3 extending into the housing 21 is connected to the end of the lower static electricity removal and dust removal module away from the lower guide roller 4. An upper guide roller 5 is provided between the end of the upper negative pressure conveyor line 22 near the upper static electricity removal and dust removal module 24 and the upper static electricity removal and dust removal module 24. The product 8 moves below the upper static electricity removal and dust removal module 24 after being guided by the upper guide roller 5 without contacting the upper static electricity removal and dust removal module 24. Several positive pressure air inlets 6 and several negative pressure air inlets 7 are provided on the side of the housing 21. An electrostatic measuring device 9 is also provided near the discharge port of the housing 21.

[0025] The equipment provided in this application involves manually placing the film product onto the product feeding conveyor, which then transports it to the housing. A lower electrostatic precipitator and dust removal module treats the static electricity and dust on the lower surface of the product. The product is then conveyed to the discharge negative pressure conveyor line, where an upper electrostatic precipitator and dust removal system treats the static electricity and dust on the upper surface. During discharge, ion air is used again for electrostatic removal, and an electrostatic measurement device measures the static electricity on the product surface. The belt and main structure are made of anti-static materials. The product neutralizes and removes static electricity from its surface through ionization. The product is subjected to turbulent airflow generated by the internal airflow and vacuum airflow. This turbulent airflow causes high-frequency micro-motion in the product, breaking down the air interface layer on the roll surface and simultaneously drawing contaminants released from the interface layer into the vacuum airflow. The dust removal capacity is related to the degree of product contamination and the operating speed, and can remove contaminant particles larger than 10 micrometers.

[0026] The upper and lower electrostatic eliminator dust removal modules have the same structure, both employing a non-contact dust removal system commonly used in this field. The dust removal head contains one ultrasonic generating chamber and two vacuum adsorption chambers. Dust particles adhere to the glass substrate surface under the action of the adsorption layer. To remove the dust particles, their adhesive force must be overcome. A blower provides clean gas at 8-16 kPa to the ultrasonic generating chamber of the dust removal head. The gas generates ultrasonic waves through the ultrasonic generator. Utilizing the energy and vibration of the ultrasonic waves, the dust particles overcome the adhesive force on the glass substrate surface, detaching from the surface through three motion modes (single or mixed): lifting, rolling, and sliding. The vacuum chamber of the dust removal head is used to adsorb the dust particles. After the dust particles are separated from the glass substrate surface, the reflection of the ultrasonic waves carries the dust particles, which are then instantly sucked away by the vacuum adsorption chamber of the cleaning head, thus achieving the effect of cleaning the dust particles from the glass surface. Since the non-contact dust removal system is a publicly disclosed technology in this field, only a simple functional description is provided in this application, without further elaboration or additional drawings.

[0027] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
