AI Technical Summary

Problems solved by technology

However, the centrifugal design cannot achieve 100% filtration in the process of filtering membrane residue, and some membrane residue will flow back into the cylinder
The reflowed film slag will condense into a block above the liquid level and block the overflow port, causing the liquid level in the cylinder to rise continuously, which in turn will cause the overflow to overflow the cylinder. In severe cases, the film slag will stick to the production plate and cause Quality defects may lead to equipment downtime, pollute the production site, and seriously disturb the normal production operation

Embodiment 1

[0047] Figure 1 to Figure 3 As shown, a liquid storage device includes a cylinder 1 for storing the solution, a power pump 2 for driving the output of the solution, and a first disturbance nozzle 3 for driving the flow of the solution, and the side wall of the cylinder 1 is opened There is an overflow port 5, the power pump 2 is installed inside the cylinder body 1, the first disturbance nozzle 3 is installed inside the cylinder body 1, the first disturbance nozzle 3 and the power pump 2 connections. The overflow port 5 is arranged on the side wall of the cylinder body 1 near the top. The power pump 2 is connected to an external spray head for spraying the surface of the copper clad laminate. By arranging the first disturbance nozzle 3, the solution is disturbed to keep the solution in a state of motion, thereby avoiding static agglomeration of film residue in the solution and blocking the overflow port 5. This solution is based on the centrifugal membrane slag filtration,...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is:

[0054] The first fixed base is installed on the cylinder body through a first lifting mechanism, and the first fixed base can drive the first nozzle branch pipe and the hole discharge pipe to move up and down. A liquid level sensor is provided on the side wall of the cylinder, and the liquid level sensor is electrically connected to the first lifting mechanism, so that the height of the drain pipe can be automatically adjusted according to the liquid level of the solution in the cylinder , so as to ensure that the drain pipe is located at the liquid level of the solution.

Embodiment 3

[0056] The difference between this embodiment and Embodiment 1 is:

[0057] The hole-discharging pipe is obliquely fixed on the branch pipe of the first spray head relative to the horizontal plane.

Abstract

The invention relates to the technical field of printed circuit board production equipment, and discloses a solution storage device. The solution storage device comprises a cylinder block used for storing solution, a power pump used for driving solution to be output, and a first disturbance nozzle used for driving solution to flow. The side wall of the cylinder block is provided with an overflow mouth. The power pump is installed inside the cylinder block. The first disturbance nozzle is installed inside the cylinder block, and the first disturbance nozzle is connected with the power pump. By setting the first disturbance nozzle connected with the power pump, solution can be disturbed continuously, membrane slag in solution is prevented from being static and caking and is further prevented from caking at the overflow mouth to block the overflow mouth, and the problem of overflow is solved.

Description

technical field [0001] The invention relates to the technical field of printed circuit board production equipment, in particular to a liquid storage device. Background technique [0002] At present, the membrane dregs filtration of the printed circuit board horizontal line generally adopts a drum design or a centrifugal design. Among them, the equipment adopting the drum type design has a large volume, high energy consumption, frequent replacement of consumables, and high production costs. The equipment with centrifugal design is small in size, low in energy consumption and low in maintenance cost, and is an environment-friendly equipment in line with the concept of clean production. However, because the centrifugal design cannot achieve 100% filtration during the process of filtering the membrane residue, part of the membrane residue will flow back into the cylinder. The reflowed film slag will condense into a block above the liquid level and block the overflow port, caus...
