Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A device for improving the unclean development of ink orifices comprises an insulating box 1, wherein two sides of the insulating box 1 are respectively fixedly connected with an output air pipe 2 and an input air pipe 3, a top of the insulating box 1 is fixedly connected with a circulating air pump 4 and a dehumidification box 5, an end of the output air pipe 2 away from the insulating box 1 is fixedly connected to the air inlet of the circulating air pump 4, and an end of the input air pipe 3 away from the insulating box 1 is fixedly connected to one side of the dehumidification box 5.

[0025] A connecting air pipe 6 is fixedly connected between the air outlet of the circulating air pump 4 and one side of the dehumidification box 5, a heating wire 7 is fixedly connected at the center of the dehumidification box 5, and a moisture-absorbing cotton layer 8 is provided inside the dehumidification box 5 and on both sides of the heating wire 7. A first infrared baking lamp 9 is fixedly installed on the top of the inner wall of the insulation box 1.

[0026] like Figure 1 The outside of the insulation box 1 is provided with an openable and closable door, which can seal the insulation box 1 when the circuit board is pre-baked inside the insulation box 1. The insulation box 1 can be connected to an external power supply, and the circulating air pump 4 and the heating wire 7 both draw power from the inside of the insulation box 1.

[0027] The top of the dehumidification box body 5 is provided with a mounting slot 10 , on which a closed pad 11 is provided, the top of which is fixedly connected with a mounting top plate 12 , and the two moisture-absorbing cotton layers 8 are both fixed to the bottom of the closed pad 11 .

[0028] like Figure 2 and Figure 3The closing pad 11 is adapted to the installation slot 10 and can close the installation slot 10 . At this time, the installation top plate 12 is located above the dehumidification box body 5 .

[0029] A clamping plate 13 is disposed on the top of the mounting top plate 12 , and positioning sleeves 14 used in conjunction with the clamping plate 13 are fixedly connected to both sides of the heat insulation box body 1 , and a fixing bolt 15 is disposed on one side of the positioning sleeve 14 .

[0030] like Figure 2 and Figure 3 There are screw holes on the positioning sleeve 14 and the clamping card 13. When the closing pad 11 closes the installation slot 10, the two moisture-absorbing cotton layers 8 are attached to the two sides of the heating wire 7, and the clamping card 13 is pressed against the top of the installation top plate 12. The two ends of the clamping card 13 are inserted into the positioning sleeve 14. At this time, the positioning sleeve 14 and the clamping card 13 can be fixed by the fixing bolts 15. Conversely, the fixing bolts 15 can be removed, the clamping card 13 and the installation top plate 12 can be moved up, and the moisture-absorbing cotton layer 8 can be pulled out, which is convenient for the replacement of the moisture-absorbing cotton layer 8.

[0031] The first solenoid valve 16 is fixedly installed on both the output air pipe 2 and the input air pipe 3 . An exhaust pipe 17 is fixedly connected to the top of the dehumidification box 5 and located on both sides of the installation slot 10 . A second solenoid valve 18 is fixedly installed on the exhaust pipe 17 .

[0032] A transverse carrier plate 19 is fixedly connected inside the heat-insulating box body 1 , a second infrared lamp 20 is mounted on the transverse carrier plate 19 , a heating protrusion component 21 is fixedly connected to the transverse carrier plate 19 , and a bearing ring 22 is fixedly connected to the outer surface of the heating protrusion component 21 .

[0033] like Figure 1 The outside of the heating protrusion 21 is made of heat-conducting material, and there is an electric heating wire inside, so that the heating protrusion 21 can generate heat. When the first infrared baking lamp 9 pre-bakes the circuit board in the insulation box 1, the second infrared baking lamp can heat the bottom of the circuit board to increase the heating speed of the circuit board. At the same time, the heating protrusion 21 is inserted into the ink orifice of the circuit board to heat the ink orifice of the circuit board and increase the ink thickness of the orifice for better curing. The pre-bake temperature in the insulation box 1 is raised to 78 degrees Celsius and maintained for 45 minutes.

[0034] Two fixing blocks 23 are fixedly connected to the inner wall of the heat-insulating box body 1 , a guide rod 24 is fixedly connected between the two fixing blocks 23 , a clamping shaft 25 is slidably connected to the guide rod 24 , and a clamping spring 26 is sleeved on the guide rod 24 .

[0035] like Figure 1When placing the circuit board into the heat-insulating box 1, the heat-generating protruding component 21 can be passed through the thin plate plug hole on the circuit board. At this time, the bearing ring 22 holds up the bottom of the circuit board, and the spring 26 moves the clamping shaft 25 downward. The clamping shaft 25 is pressed on the top of the circuit board to facilitate pre-baking of the circuit board.

[0036] The working principle of the device for improving the unclean ink opening development provided by the utility model is as follows:

[0037] When the circuit board is pre-baked in the heat-insulating box 1, the first solenoid valve 16 is opened, the second solenoid valve 18 is closed, and then the circulating air pump 4 is started to extract the gas inside the heat-insulating box 1 through the output air pipe 2, and then input it into the dehumidifying box 5 through the connecting air pipe 6. When the gas passes through the hygroscopic cotton layer 8 inside the dehumidifying box 5, the hygroscopic cotton layer 8 absorbs moisture, and then inputs it into the heat-insulating box 1 through the input air pipe 3;

[0038] After dehumidification is completed, the first solenoid valve 16 is closed, the second solenoid valve 18 is opened, and the heating wire 7 is energized to generate heat. At this time, the heating wire 7 evaporates the moisture in the hygroscopic cotton layers 8 on both sides, so that the evaporated humid air is output to the outside of the dehumidification box 5 through the exhaust pipe 17.

[0039] Compared with the related art, the device for improving the ink orifice development problem provided by the utility model has the following beneficial effects:

[0040] The utility model drives the air inside the heat-insulating box 1 through the circulating air pump 4, circulates through the input air pipe 3, the output air pipe 2 and the connecting air pipe 6, and uses the moisture-absorbing cotton layer 8 to absorb moisture from the circulating air to ensure the dryness of the inside of the heat-insulating box 1. When the heat-insulating box 1 is used to dry the circuit board, it is avoided that the humidity inside the heat-insulating box 1 is too high, which may cause the ink holes to be unclean, so that the ink cannot be normally washed away after exposure.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
