Abstract

The utility model discloses an apparatus used in the field of printed circuit boards (PCB) processing, in particular to a solution tank. The solution tank comprises a tank body, a solution discharge port, a solution discharge channel and a first filter screen; the solution discharge port is formed at the bottom of the tank body; the solution discharge channel is positioned under the tank body, and is connected with the solution discharge port; the first filter screen is arranged at the solution discharge port or in the solution discharge channel; and a second filter screen used for the preliminary filtration of the solution is also arranged in the tank body. As the second filter screen is added, solution is effectively filtered in advance by utilizing the second filter screen before the solution flows to the solution discharge port, the discharge of the solution at the first filter screen is speeded up, the production efficiency is improved, the solution discharge port and the solution discharge channel are prevented from being blocked, and the maintenance frequency of the blocked solution discharge channel is reduced.

Description

A kind of PCB processing solution tank

Technical field

The utility model relates to the utensil that a kind of PCB manufacture field is used, and specifically is meant a kind of solution tank.

Background technology

Can often use some solution tanks in the PCB industry, remove the green oil solution tank such as PCB, PCB half tone rinse bath etc., this type of solution tank generally comprises cell body, leakage fluid dram, apocenosis passage and screen pack, the leakage fluid dram operated by rotary motion is in the cell body bottom and near sidewall, apocenosis passage links to each other with leakage fluid dram, screen pack is arranged in leakage fluid dram place or the apocenosis passage, and in order to play a role in filtering, the mesh of screen pack can not be too big, so after PCB product ordinary production, during discharge opeing, screen pack is stopped up by impurity easily, causes solution flow rate slow, pipe-dredging frequency of maintenance height influences production efficiency.

The utility model content

The technical problem that the utility model mainly solves provides the not susceptible to plugging solution tank of a kind of quick fluid-discharge, leakage fluid dram.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of PCB processing solution tank, comprise cell body, leakage fluid dram, apocenosis passage and first screen pack, leakage fluid dram is arranged on the cell body bottom, apocenosis passage is positioned at the cell body below and links to each other with leakage fluid dram, first screen pack is arranged in leakage fluid dram place or the apocenosis passage, it is characterized in that: also be provided with second screen pack that solution is tentatively filtered in the described cell body.

The beneficial effects of the utility model are: because the utility model has increased by second screen pack, before solution flows to leakage fluid dram, utilize second screen pack effectively solution all to be filtered once in advance earlier, so reduce in the first screen pack place filtrate, drain age velocity is accelerated, enhance productivity, can also prevent leakage fluid dram and apocenosis passage to stop up, reduce the frequency of apocenosis passage mediation maintenance.

If also be provided with heating tube in the cell body of solution tank; when picking and placeing Hanging Basket or product; easily heating tube is hit distortion; even break; the utility model is trapped among heating tube in the preliminary filtration zone that second screen pack and cell wall surround; second screen pack can also play a protective role, and has protected heating tube not hit ring by Hanging Basket or product effectively.

Description of drawings

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is embodiment one schematic diagram of PCB processing described in the utility model with solution tank;

Fig. 2 is embodiment two schematic diagrames of PCB processing described in the utility model with solution tank.

Wherein, 1, cell body; 2, apocenosis passage; 3, leakage fluid dram; 4, first screen pack; 5, second screen pack; 6, preliminary filtration zone; 7, heating tube; 8, draw-in groove.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

As first embodiment of PCB processing described in the utility model with solution tank, see also Fig. 1, solution tank comprises cell body 1, leakage fluid dram 3, the apocenosis passage 2 and first screen pack 4, cell body 1 is square, leakage fluid dram 3 is arranged on cell body 1 bottom, apocenosis passage 2 is positioned at the cell body below and links to each other with leakage fluid dram 3, first screen pack 4 is arranged on leakage fluid dram 3 places, also be provided with second screen pack 5 that solution is tentatively filtered in the cell body 1, second screen pack 5 overlaps with two adjacent sidewalls of cell body 1, and surround a preliminary filtration zone 6 with two cell walls, leakage fluid dram 3 is enclosed in this zone, the upper edge of second screen pack 5 is concordant with cell body 1 upper edge, and the mesh of second screen pack 5 is more than or equal to the mesh of first screen pack 4, and second screen pack 5 can be by hook, modes such as securing member are arranged on the cell body 1.

Because the utility model has increased by second screen pack, before solution flows to leakage fluid dram, utilize second screen pack effectively solution all to be filtered once in advance earlier, because the second screen pack filter area is bigger, can not influence the solution flow rate at the first screen pack place, be difficult for stopping up yet, through tentatively filtering, the first screen pack place filtrate reduces, solution filters smooth and easy, and drain age velocity is fast, has improved production efficiency, can also prevent leakage fluid dram and line clogging pipe, reduce the frequency of maintenance of apocenosis passage mediation.

As second embodiment of PCB described in the utility model processing with solution tank, see also Fig. 2, be also to be provided with in the cell body 1 heating tube 7 with the difference of embodiment one, heating tube 7 also is enclosed in the described preliminary filtration zone 6.Second screen pack 5 is parallel with the pair of sidewalls of cell body, and the edge that cell body 1 is provided with draw-in groove 8, the second screen packs 5 inserts draw-in groove 8, thereby is fixed in the cell body 1, and second screen pack 5 is the pull-type structure, can take out replacing like a cork, cleans very convenient; Second screen pack can also play a protective role, and has protected heating tube not hit ring by Hanging Basket or product effectively.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
