Abstract
The utility model discloses an anti-welding development device for a PCB, which comprises a development tank, a water outlet pipe, a water pump, a connecting pipe, a filtering tank, a filter screen and a development spray pipe, wherein one end part of the water outlet pipe is communicated with the development tank; the water pump is communicated with the other end part of the water outlet pipe; the lower end part of the connecting pipe is communicated with the water pump; the filtering tank is communicated with the upper end part of the connecting pipe; the filter screen is covered in the filtering tank longitudinally; the development spray pipe is communicated with the filtering tank; the filter screen is positioned between the connecting pipe and the development spray pipe; the upper end part of the connecting pipe is higher than the development spray pipe; the water pump is used for pumping medicinal liquid in the development tank into the filtering tank; ink residue in the medicinal liquid is filtered through the filter screen in the filtering tank; filtered medicinal liquid flows out of the development spray pipe; the development on the PCB is carried out, the development quality is improved, the service life of the medicinal liquid is prolonged, the production cost is lowered, and the structure is simple.
Description
Technical field
The utility model relates to a kind of pcb board welding masking developing device.
Background technology
Current pcb board welding masking developing device, comprise developing trough, the rising pipe that one end is connected with described developing trough, the water pump be connected with the other end of described rising pipe, the connecting pipe that bottom is connected with described water pump, the development jet pipe be connected with the upper end of described connecting pipe, liquid medicine in developing trough is extracted out by water pump, and by the development jet pipe, be sprayed onto on the PCB plate be placed on developing trough, pcb board is developed, after development treatment, liquid medicine flows back in developing trough and reuses again, because changing the groove cycle, liquid medicine grows (being generally 7-9 days), after development, in developing trough, ink slag is more, because the liquid medicine in developing trough does not pass through filtration treatment, had a strong impact on the serviceable life of development quality and development liquid medicine.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of pcb board welding masking developing device is provided, the liquid medicine in developing trough can be filtered, thus the serviceable life of prolongation liquid medicine.
For achieving the above object, the technical solution of the utility model has been to provide a kind of pcb board welding masking developing device, comprise developing trough, the rising pipe that one end is connected with described developing trough, the water pump be connected with the other end of described rising pipe, the connecting pipe that bottom is connected with described water pump, also comprise the lautertuns be connected with the upper end of described connecting pipe, vertically be covered in the screen pack in described lautertuns, the development jet pipe be connected with described lautertuns, described screen pack is between described connecting pipe and described development jet pipe, the upper end of described connecting pipe is higher than described development jet pipe.
As preferably, the bottom of described connecting pipe is higher than described rising pipe.
As preferably, axially all the paralleling with horizontal line of axial, the described development jet pipe of described rising pipe.
As preferably, described screen pack is connected by web member with described lautertuns, and described screen pack is connected mutually with described web member with dismantling.
Advantage of the present utility model and beneficial effect are: water pump is by the liquid medicine suction lautertuns in developing trough, by the screen pack in lautertuns, the ink slag in liquid medicine is filtered, liquid medicine after filtration is flowed out by the development jet pipe again, pcb board is developed, improved the development quality, extend the serviceable life of liquid medicine, reduced production cost, and simple in structure.
The accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
In figure: 1, developing trough; 2, rising pipe; 3, water pump; 4, connecting pipe; 5, lautertuns; 6, screen pack; 7, development jet pipe; 8, web member.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of pcb board welding masking developing device, comprise developing trough 1, the rising pipe 2 that one end is connected with described developing trough 1, the water pump 3 be connected with the other end of described rising pipe 2, the connecting pipe 4 that bottom is connected with described water pump 3, also comprise the lautertuns 5 be connected with the upper end of described connecting pipe 4, vertically be covered in the screen pack 6 in described lautertuns 5, the development jet pipe 7 be connected with described lautertuns 5, described screen pack 6 is between described connecting pipe 4 and described development jet pipe 7, the upper end of described connecting pipe 4 is higher than described development jet pipe 7.That described connecting pipe 4 can be is U-shaped, arc etc., and concrete shape is unrestricted.
As shown in Figure 1, the bottom of described connecting pipe 4 is higher than described rising pipe 2.
As shown in Figure 1, axial, the described development jet pipe 7 of described rising pipe 2 axially all parallels with horizontal line.
As shown in Figure 1, both are connected described screen pack 6 and described lautertuns 5 by web member 8, and described screen pack 6 is connected mutually with described web member 8 with dismantling.Screen pack 6 can be disassembled cleaned or keeped in repair, replacing etc., use more convenient.
Principle: water pump 3, by the liquid medicine suction lautertuns 5 in developing trough 1, filters the ink slag in liquid medicine by the screen pack 6 in lautertuns 5, and the liquid medicine after filtration is flowed out by development jet pipe 7 again, and pcb board is developed.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
