6800E Full-automatic PCB washer machine

6800E  Full-automatic PCB washer

·  6800E series automatic PCBA washing machine; It is an online full-automatic special cleaning machine for PCBA board, which is suitable for traditional plate washing water and does not require manual contact with cleaning agent. The equipment combines PCB transmission technology and brush cleaning technology, which can be brushed in multiple ways in front, back, left and right directions to ensure that PCBA board meets the cleaning requirements. It is suitable for cleaning the welding surface of single-sided PCBA board without wetting the front components.

1.features ：

· This machine has unique body structure, stable performance and the highest cleaning effect in the industry

· 

· · It is specially used for cleaning tin beads, flux traces and scratches

· 

· · Imported brown bristle brush and anti-static brush will not generate static electricity and will not damage PCB board

· 

· · Suitable for PCB board with edges (at least 1.5mm away), 10-300mm wide, thickened spring claw to ensure that PCB board will not shift during transportation

· 

· · Automatic cleaning agent coating system: ensure that the PCB welding surface can be evenly coated with cleaning water without affecting the surface of other parts.

· 

· · Disc brush+two rollers: ensure that the PCB board is clean in all directions without dead corners.

· 

· · The height and rotation speed of the cleaning brush can be adjusted to meet different cleaning requirements.

· 

· · Wastes generated from work will automatically gather in the filter box at the lower part of the machine for easy cleaning

· 

· · It is driven by high-quality electronic speed-regulating motor, whose speed is stepless adjustable and durable.

· · 220 V power supply is adopted. Easy to use

· · Adopt brand electrical appliances and control system to ensure the reliability and stability of the control system

· Adopt modular control。

4.Cleaning structure and function

·  Equipment structure: including loading and connecting mechanism, transportation mechanism, brush cleaning system, circulating filtration system, air drying system, PLC program controller, and other automatic control systems. Each system is of independent modular design, which is easy to operate and maintain.

· 

· · The whole machine realizes automatic control through PLC, with complete functions, and has two operation modes: fully automatic and manual. The automatic mode is (economic operation mode), which can greatly reduce the consumption of cleaning agent and electric energy.

· 

· · The disc brush and the roller brush shall clean the bottom of the PCB board in all directions at the same time, front and back, left and right, without dead corners;

· 

· · The cleaning module is equipped with a completely closed three-level automatic circulating filtration system, which continuously filters and cleans the subsequent stains, so that the cleaning fluid always remains in a high level of activity, and the cleaning fluid is recycled.

· 

· · The cleaning fluid tank is equipped with low level alarm and over-limit level alarm functions.

· 

· · Air drying device, which acts on the cleaned PCB board through a fan to make its surface dry quickly.

· 

· The motor of wet cleaning module and dry cleaning module are independent, and the speed and height can be adjusted independently. Suitable for various PCBs

· Plate cleaning process

· · Primary and secondary brush wet cleaning modules: primary and secondary brush cleaning modules, including two sets of abrasive brushes and two sets of spray pipes, which rotate in reverse direction to brush the PCB board, and the cleaning fluid flows back to the circulating system.

· 

· · Primary dry-cleaning module: it contains a set of disc brown brush, which is used to clean the PCBA board by reverse rotation.

· 

· l Secondary wet cleaning module: it includes a set of roller abrasive brushes, a set of spray pipes, and reversely rotates to brush the PCBA board, and the cleaning liquid returns to the circulating system.

· 

· l Secondary dry cleaning module: it contains a set of disc brown brush, which is rotated forward to clean the PCBA board.

6.Level control device：

When the liquid level in the cleaning liquid tank drops to the low level warning line, the liquid level controller will send an alarm signal to prompt manual liquid replenishment.

7.Feed structure and conveying system:

The feeding device synchronized with the transport guide rail is convenient and smooth for feeding

 The whole process of transportation is visual, which can clearly observe the operation of PCB board inside the machine

8.Circulating filtration system

Cleaning tank → liquid storage tank → primary filtration → sedimentation tank → liquid storage tank → circulating pump → return to cleaning tank for recycling

9. control system:

Control mode: divided into manual operation/intelligent economic operation

1. Manual operation mode: each system function can be completed manually one by one

2. Intelligent and economical operation mode: when there is no PCBA board in the machine, the system will automatically judge, and then the brush will be cleaned, and the water pump will enter the stop state. The cleaning fluid circulation system is fully closed.
