Description

Technical Field

[0001] The present invention relates to the technical field of control mainboard polishing, and in particular to an edge protection type polishing device for control mainboard production. Background Art

[0002] In the modern electronics manufacturing industry, the control motherboard is one of the core components, responsible for coordinating and managing various operations within the equipment. Every link in the control motherboard production process is directly related to the performance and quality of the product. Edge processing is one of the key steps in control motherboard manufacturing, aimed at eliminating burrs, irregular shapes and other surface defects caused by cutting or stamping processes.

[0003] During the grinding process of the control board edge, the high-speed friction between the grinding tool and the control board will generate a large amount of metal or plastic debris. These debris are ejected outward from the grinding area at a very high speed and easily scatter on the surface of the control board. During the grinding process, coolant is used to cool the control board. During the high-pressure spraying process, the coolant will also splash onto the surface of the control board along with the debris.

[0004] The control motherboard has a high-precision circuit design and a complex component layout. Any tiny debris may be embedded in the gaps of the control motherboard, causing problems such as short circuits or signal interference. The coolant remaining on the surface of the control motherboard may absorb moisture, causing electrochemical corrosion and irreversible damage. To ensure the quality of the control motherboard, in the subsequent stages of production, the debris and coolant on the control motherboard are generally removed through ultrasonic cleaning, high-pressure air gun blowing or chemical solvent wiping. These cleaning methods not only consume a lot of time and human resources, but may also lead to additional waste of resources, such as water resources and cleaning agents. Summary of the Invention

[0037] The staff puts the control main board on the conveyor 154 on the left, and the conveyor 154 on the left conveys the control main board to the right and conveys the control main board to between the two installation boxes 6 on the left. Then the screw motor 157 is controlled to drive the lifting plate 156 to move upward, and the lifting plate 156 drives the lifting plate 158 to move upward to lift the control main board so that the control main board and the rubber ring 14 are flush. Then the movable end of the electric push rod 159 is controlled to extend to drive the pressure plate 1510 to move downward, and the pressure plate 1510 drives the pressure block 1511 to move downward to press the control main board so that the control main board cannot move, ensuring that the control main board can smoothly enter the installation box 6. Then the dual-axis motor 4 on the left drives the driving screw 5 on the left to rotate, driving the two slides 3 on the left to move toward each other. The control mainboard moves in the direction of approaching, thereby driving the two installation boxes 6 on the left to move in the direction of approaching each other, the control mainboard will pass through the rubber ring 14 and extend into the installation box 6 and contact the grinding wheel 12.

The slider 8 moves to the right and can also drive the chamfering wheel 172 to move to the right. The chamfering wheel 172 will contact the corners of the control mainboard. The output shaft of the drive motor 11 drives the rotating shaft 171 to rotate through the pulley group, and the rotating shaft 171 drives the chamfering wheel 172 to rotate. The angle wheel 172 can chamfer the edges and corners of the control mainboard. The staff can connect the connecting pipe 165 to the coolant. The coolant flows into the hard pipe 162 and the liquid guide pipe 163 through the connecting pipe 165. Then the coolant is sprayed out through the nozzle 164 and sprayed onto the grinding wheel 12, the chamfering wheel 172 and the control mainboard to cool the grinding wheel 12, the chamfering wheel 172 and the control mainboard. The mounting plate 13 can block the coolant and debris, and the rubber ring 14 can seal the gap between the control mainboard and the mounting plate 13, thereby preventing the coolant and debris from flying onto the control mainboard. Therefore, the polished control mainboard does not need to be subsequently cleaned, thereby saving resources. After the control mainboard is polished, the dual-axis motor 4 on the left drives the drive screw 5 on the left. The two mounting boxes 6 on the left side rotate in the opposite direction, thereby driving the two mounting boxes 6 on the left side to move away from each other, and the polished control mainboard will be removed from the mounting box 6. The part of the control mainboard located in the mounting box 6 may be splashed with coolant and debris. When the polished control mainboard is removed from the mounting box 6, the rubber ring 14 can scrape off the coolant and debris to prevent the coolant and debris from remaining on the polished control mainboard. After the polished control mainboard is removed from the mounting box 6, the movable end of the control electric push rod 159 is shortened to drive the pressure block 1511 to move upward, and the pressure block 1511 is disengaged from the polished control mainboard. Then, the control screw motor 2 157 is controlled to drive the lifting plate 158 to move downward, and the polished control mainboard is placed back on the conveyor 154.The conveyor 154 conveys the polished control motherboard to the right and transports the polished control motherboard to the conveyor 154 on the rotating plate 151. The output shaft of the reduction motor 152 drives the rotating plate 151 to rotate, thereby driving the polished control motherboard to rotate 90 degrees, turning the polished control motherboard. The above operation is repeated, and the left and right sides of the control motherboard are inserted into the two installation boxes 6 on the right side to polish and chamfer the left and right sides of the control motherboard. Conveying equipment can be set on the left and right sides of the rack 1. The conveying equipment transports the unpolished control motherboard to the conveyor 154 for loading.
