AI Technical Summary

Technical Problem

When cleaning the circuit board for car display screen, cleaning liquid is easily entered inside the connector of the circuit board, causing the cleaning liquid to remain in the gaps of the connector, affecting the cleaning effect.

Method used

A circuit board dust removal device for vehicle-mounted display screen is designed, including a cleaning tank, a support rod, a mounting frame, a telescopic rod, a clamping rod, a top rod, a gear and a rack. Through the design of clamping rods and top rods, different specifications of circuit boards are adapted to the circuit boards, and the rotation of the circuit boards and the throwing of cleaning liquid are achieved through the driving of gears and racks.

Benefits of technology

Through the design of the clamping rod and the top rod, the contact area between the circuit board and the cleaning liquid is increased, and more sufficient cleaning is achieved; through the driving of gears and racks, the cleaning liquid in the jack is effectively thrown out, improving the cleaning effect.

Abstract

The invention relates to the field of circuit board cleaning, and particularly discloses a circuit board dust removal device for a vehicle-mounted display screen, the circuit board dust removal device comprises a cleaning pool, a supporting rod is mounted above the cleaning pool, a mounting rack is slidably connected to the supporting rod, a telescopic rod is mounted on one side of the cleaning pool, and a lifting function is realized through the telescopic rod and the mounting rack; the mounting frame comprises a mounting plate, a plurality of clamping rods used for fixing the circuit board are slidably connected to the mounting plate, a plurality of ejector rods used for separating the circuit board are inserted into the mounting plate, one end of each ejector rod is slidably connected with a moving plate, one end of each moving plate is fixedly connected with a gear, and a rack is fixedly connected to the upper portion of one side of the cleaning pool and engaged with the gear. According to the invention, the circuit board can form a gap with the mounting plate after being mounted through the ejector rod, so that the contact area between the circuit board and the cleaning liquid is increased, and the cleaning is more sufficient. The mounting plate can be driven to rotate through the mounting frame, and the mounting plate rotates to drive the circuit board to rotate, so that residual cleaning liquid in the multiple jacks can be thrown out.
