Description

Vacuum etch device
Technical field
The utility model relates to a kind of improvement of vacuum etch device.
Background technique
Etaching device uses extensive currently on the market, it is common that carries out liquid medicine etching to production plate surface by nozzle, no Cross the operation mode etching low precision with it is inefficient, on nowadays high speed development electronics market, the requirement of plate to be processed Also higher and higher, quantitatively production has become trend.In order to meet the development that enterprise adapts to market, especially in PCB In the processing of plate ultraprecise, vacuum etch device becomes the emphasis of research and development.
Summary of the invention
Based on this, it is necessary to carry out process modification for existing plate Etaching device to be processed, provide a kind of precision it is high and It can avoid the vacuum etch device that " pool effect " occurs.
The above-mentioned technical purpose of the utility model has the technical scheme that
Vacuum etch device, including body, body are equipped with delivery wheel group, spray structure, it is characterised in that: the conveying Wheel group includes wheel group and lower whorl group on corresponding to each other, and vaccum suction pipe is equipped with above upper wheel group, and the vaccum suction pipe passes through support Block is connected to above wheel group, and vaccum suction pipe passes through connecting tube and vaccum suction pipe work pumping connection.
As a preferred embodiment, the vaccum suction pipe is higher than upper wheel group 2-3mm, and the difference in height of formation ensure that be generated Produce plate not snap-gauge under adsorbed state.
As another preferred embodiment, the upper wheel group is all made of acidproof base material with lower whorl group and is made, and increases and uses Service life.
Further, vaccum suction pipe is flat, and bottom surface both sides are equipped with aperture, and centre is equipped with strip hole, and vaccum suction pipe The etching solution of plate surface to be produced is sufficiently extracted under negative pressure state, to prevent the generation of " pool effect ".
Further, the supporting block lower end is placed on the wheel shaft of wheel group.
In conclusion the utility model has the following beneficial effects:
1, the upper wheel group and lower whorl group are all made of acidproof base material and are made, and increase service life.
2. vaccum suction pipe is connected to above upper wheel group by supporting block, greatly reduce with the contact surface of plate to be produced, height It protects plate surface to be produced and prevents the hidden danger of plate motion profile offset to be produced.
3. vaccum suction pipe bottom surface both sides are equipped with aperture, centre is equipped with strip hole, and vaccum suction pipe is abundant under negative pressure state The etching solution of plate surface to be processed is extracted, uniformly the etch-rate at plate edges of boards and plate centre to be processed position, to prevent " pond The generation of effect ".
Detailed description of the invention
Fig. 1 is the structural schematic diagram of vacuum etch device in the utility model.
Fig. 2 is the utility model vaccum suction pipe and upper wheel group position relationship structural diagram.
Fig. 3 is the utility model vaccum suction pipe and upper wheel group positional relationship side view.
1 in figure it is vaccum suction pipe, 2 be supporting block, 3 be upper wheel group, 4 be lower whorl group, 5 is pvc pipe.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs The limitation for the specific embodiment opened.
As shown in Figure 1, vacuum etch device, including body, body is equipped with liquid bath, delivery wheel group, spray structure, described Delivery wheel group includes wheel group 3 and lower whorl group 4 on corresponding to each other, and vaccum suction pipe 1, the vaccum suction pipe 1 are equipped with above upper wheel group 3 It is connected to upper 3 top of wheel group by supporting block 2,2 lower end of supporting block is placed on the wheel shaft of wheel group 3.Vaccum suction pipe 1 passes through Connecting tube and vaccum suction pipe work pumping connection.The outlet end of vaccum suction pipe work pumping connects three be made of eight Venturi tubes The other end of one end of the supervisor of siphunculus, the supervisor of the tee tube accesses in liquid bath, and the branch pipe of the tee tube is connected with PVC Pipe 5, the end of pvc pipe 5 are connected with vaccum suction pipe 1.
The spray structure includes spray pump, upper spray tube and lower spray tube, and the spray pump liquid feeding end connects liquid bath, spray The output end for drenching pump connects upper spray tube by pipeline and lower spray tube, upper spray tube and lower spray tube are respectively arranged at upper roller The two sides up and down for the plate circuit diameter to be processed that piece is constituted between downlink rumble wheel group.
The vaccum suction pipe 1 is higher than upper wheel group 2-3mm, and the difference in height of formation ensure that plate to be produced under adsorbed state Not snap-gauge.
The upper wheel group 3 is all made of acidproof base material with lower whorl group 4 and is made, and increases service life.
Vaccum suction pipe be it is flat, bottom surface both sides are equipped with aperture, and centre is equipped with strip hole, and vaccum suction pipe is in negative pressure state The etching solution of plate surface to be produced is sufficiently extracted down, to prevent the generation of " pool effect ".
Workflow is summarized:
When specifically used, spray pump extracts the medical fluid in liquid bath, and liquid medicine jet is poured plate to be produced by upper main jet shower pipe Surface, vaccum suction pipe work pump the medical fluid in extract slot and are generated in vaccum suction pipe by the liquid flow speed difference in Venturi tube Negative pressure, vaccum suction pipe draw the medical fluid of plate surface to be produced, by the soft Venturi tube returned to close to major trough side, from this Venturi tube Outlet return to etching major trough in.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
