In one embodiment, after the sealing process is performed on the sealing member of the three-proofing camera device, the method further includes: and in a preset time, carrying out colloid drying treatment on the three-proofing camera device. In this embodiment, after the three-proofing camera device is subjected to the sealing process, a sealing adhesive exists at each sealing position of the three-proofing camera device. Because the sealant has certain moisture, the sealant has a plurality of holes with extremely small apertures after being sealed, and external air is easily led into the three-proofing camera device. In order to further reduce the probability of entering of external air, the three-proofing camera device subjected to the sealing glue treatment is dried again, so that the moisture in the sealing glue is evaporated, and the sealing glue shrinks after being dried, so that the pores on the sealing glue after the moisture is removed are reduced, and the probability of entering of the external air into the three-proofing camera device is further reduced. In another embodiment, the colloid drying process performed on the three-prevention imaging device is specifically a standing process performed on the three-prevention imaging device for more than 12 hours, that is, the preset time is more than 12 hours, and the colloid drying process is a standing process.
In one embodiment, the performing nitrogen charging on the image pickup apparatus to be charged includes: and evacuating the camera device to be filled so as to vacuumize the interior of the camera device to be filled. In this embodiment, fill nitrogen treatment and be earlier right wait to fill camera device's inside and carry out the air and take out, make wait to fill the inside air of camera device and all take out, thereby make wait to fill the inside of camera device and demonstrate the vacuum state, be convenient for with wait to fill residual air in camera device and clear away, reduced wait to fill the condition that residual air formed water smoke on three proofings camera lens in the camera device, further improved three proofings camera's leakproofness.
In another embodiment, the evacuating the image pickup device to be charged further includes: and filling nitrogen into the camera device to be filled so as to enable the internal pressure of the camera device to be filled to reach the preset pressure. After the air in the camera device to be charged is pumped out, the interior of the camera device to be charged is in a vacuum state, residual air in the interior of the camera device to be charged is removed, and the interior of the camera device to be charged is in a negative pressure state relative to the exterior. In order to reduce the situation that outside air enters the interior of the camera device to be filled through a gap under negative pressure, the camera device to be filled is vacuumized and then is filled with nitrogen, namely the nitrogen is filled into the interior of the camera device to be filled, and water vapor is not easily formed in the interior of the camera device to be filled by virtue of the inertia characteristic of the nitrogen, so that the probability of water mist formation on the lens of the three-proof camera is reduced.
Further, the filling of nitrogen gas into the to-be-filled image pickup device further includes: and carrying out air bleeding treatment on the camera device to be charged so as to enable the internal pressure of the camera device to be charged to be matched with the atmospheric pressure. In this embodiment, after the inside of the image capturing device to be inflated is filled with the inert gas nitrogen, the internal pressure of the image capturing device to be inflated is changed from a vacuum state to a positive pressure state, so that a positive pressure appears inside the image capturing device to be inflated, which is also formed after the nitrogen in the image capturing device to be inflated is completely inflated. In order to avoid damage caused by overlarge internal pressure of the to-be-charged camera device, the to-be-charged camera device is subjected to deflation processing, namely, partial gas in the to-be-charged camera device is released through an air tap on the to-be-charged camera device, so that the inside of the to-be-charged camera device is equal to the external environment, and the balance of the internal pressure and the external pressure of the to-be-charged camera device is realized. In another embodiment, when the deflation process is performed on the to-be-inflated image pickup device, the air tap of the to-be-inflated image pickup device is placed upwards, and at this time, the nitrogen gas in the to-be-inflated image pickup device sinks, that is, the gas in the to-be-inflated image pickup device is layered into the nitrogen gas at the lower layer and the residual air at the upper layer. Therefore, for the deflation processing of the camera device to be inflated, on one hand, the balance of the internal and external air pressures of the camera device to be inflated is ensured, on the other hand, the residual air in the camera device to be inflated is further removed, the reduction of the residual air amount in the camera device to be inflated is further ensured, and the sealing performance of the three-prevention camera is further improved.
It can be understood that the nitrogen filling treatment of the camera device to be filled is realized by discharging residual air in the camera device to be filled, namely, the residual air which is easily heated to generate steam is discharged by virtue of the stable characteristic of inert gas nitrogen, so that the probability of water mist formation on the lens of the three-proofing camera is effectively reduced.
However, in the sealing process of the sealing element of the three-proofing camera device, the sealing compound is applied to the incoming line column, so that only the gap between the incoming line column and the rear cover of the three-proofing camera device can be solved, that is, the situation that air enters the three-proofing camera from the gap between the incoming line column and the rear cover of the three-proofing camera device is reduced, but the air in the transmission line connected with the incoming line column enters the three-proofing camera, that is, the gap between the wires exists in the transmission line, and the external air is guided into the three-proofing camera through the gaps.
In order to reduce the air and get into through the transmission line of being connected with the inlet wire post probability in the three proofings camera, seal the glue processing to three proofings camera device's sealing member, obtain waiting to fill camera device, later still include following step:
connecting the transmission line to the wire inlet column;
and carrying out secondary sealing treatment on the transmission line connected with the wire inlet column to seal the gap between the inner layer wires of the transmission line.
In this embodiment, the transmission line includes insulating protective layer and many signal lines, promptly the transmission line is the line of gathering a bundle that many wires formed, insulating protective layer with the inlet wire post is connected, many the signal line set up in the insulating protective layer, many the signal line be used for with main control board in the three proofings camera device is connected. The transmission line is subjected to secondary glue sealing treatment, a layer of protective inner film is formed in the insulating protective layer, and gaps between the signal lines are sealed and blocked by the protective inner film, so that the interior of the three-proofing camera device is isolated from the exterior through the protective inner film, and the phenomenon that external air enters the interior of the three-proofing camera through the transmission line is effectively reduced.
Further, since a part of air still exists from the protective inner film formed in the transmission line to the inlet post before the transmission line is fixed on the inlet post, the part of air is difficult to remove in the nitrogen charging treatment, because the part of air is located outside the three-proofing camera device, even if the nitrogen charging treatment is performed on the camera device to be charged, the part of air still cannot be completely discharged from the air nozzle. In order to facilitate the discharge of air in the transmission line, even if the space between the protective inner film and the inner side of the three-proofing camera device is filled with nitrogen, the nitrogen filling treatment of the camera device to be filled comprises the following steps:
carrying out overcharging operation on the camera device to be charged so as to enable the air pressure in the camera device to be charged to reach a first preset air pressure;
and performing overdischarge operation on the camera device to be charged so that the air pressure in the camera device to be charged reaches a second preset air pressure.
In this embodiment, the first preset air pressure is greater than the second preset air pressure, the to-be-charged camera device performs the overcharge operation, and the to-be-charged camera device is charged with excessive nitrogen through an air tap, so that the air pressure in the to-be-charged camera device reaches the first preset air pressure, and the first preset air pressure is greater than atmospheric pressure, for example, the first preset air pressure is 2.5 times of standard atmospheric pressure. In the overcharging operation, the to-be-charged camera device is internally provided with charged nitrogen and residual air at the same time, the nitrogen and the residual air are jointly extruded in the to-be-charged camera device, so that the inner wall of the to-be-charged camera device is in an overpressure extrusion state, the transmission line communicated with the to-be-charged camera device is filled with the nitrogen at the moment, the residual air in the transmission line is extruded into the to-be-charged camera device, and the residual air at each part is gathered in the to-be-charged camera device. Like this, it is right when waiting to fill camera device and going on the operation of putting excessively, under the effect of internal and external pressure difference, wait to fill the gas in the camera device and be released, wherein, because nitrogen gas is heavier than in the air, moreover, the air cock is placed upwards, and the nitrogen gas deposit is in wait to fill camera device's bottom, the residual air of being convenient for is preferentially extruded. In addition, the over-discharge operation not only discharges air, but also discharges a part of nitrogen, so that after the nitrogen is discharged and the air pressure reaches the second preset air pressure, the air remained in the camera device to be charged can be completely discharged, for example, the second preset air pressure is 1.21 times of the air pressure.
Furthermore, during the over-releasing operation of the camera device to be charged, an operator needs to stare at the barometer in real time, and the deflation of the air nozzle is closed when the second preset air pressure is reached, so that the operation is inconvenient. In order to facilitate timely and accurate ending of the overdischarge operation, the overdischarge operation is performed on the to-be-charged camera device, and the method further comprises the following steps of:
acquiring the over-discharge gas density of the gas nozzle;
