[0037] When the electronic device moves into the inside of the detection box 5, at this time, the two partitions 7 are respectively located in the two end ports of the detection box 5, the cover plate 18 is opened, the electrical connection head at the end of the connecting line is inserted into the plug interface of the electronic device through the slot 17, so that the voltage of the electronic device in the normal state can be detected by the voltmeter 16 first, after the normal state detection is completed, the electric water heater in the water tank 10 is started to work, the electric water heater heats the water in the water tank 10 to generate water vapor, the water vapor is introduced into the inside of the detection box 5 through the gas conveying pipe 12, after a certain time, when the inside of the detection box 5 is basically filled with water vapor, the sealing assembly 1 is arranged to expand and seal the gap between the two partitions 7 and the two end ports of the detection box 5, so that a relatively closed space is formed in the inside of the detection box 5, the leakage and waste of water vapor are greatly reduced, the energy consumption is reduced, the humidity in the detection box 5 is maintained stable, the detection process is not disturbed by the outside, so that the voltage of the electronic device in the case of high humidity can be detected more accurately, the accuracy and reliability of the detection are effectively improved, then the sealing of the sealing assembly 1 is released, the hot air blower 9 is started to work, hot air is conveyed into the inside of the detection box 5 through the hot air blower 9, the hot air flow discharges the air in the inside of the detection box 5, the inside of the detection box 5 is heated through the hot air, so that the voltage of the electronic device in the case of high temperature can be detected, the ports of the detection box 5 can also be sealed through the sealing assembly 1, the hot air blower 9 can also output cold air flow, a certain amount of air flow is input into the relatively closed detection box 5 through the hot air blower 9, the air pressure in the inside of the detection box 5 is increased, so that the voltage of the electronic device in the case of a certain air pressure can be detected, so that a variety of environments can be simulated to comprehensively test the electronic device; the multiple electronic devices are intermittently moved into the inside of the detection box 5 through the setting of the shifting assembly 4, so that the electronic devices are sequentially detected one by one, the continuity of the electronic device detection is effectively improved, the overall detection work efficiency is greatly improved, the error of manual operation is reduced, and the manual workload in the detection process is reduced; when the sealing assembly 1 expands to seal the ports of the detection box 5, the sealing assembly 1 triggers the auxiliary ejection assembly 2 to work, so that the electronic device which has completed the detection and is moved out of the detection box 5 is automatically pushed out through the auxiliary ejection assembly 2, the electronic device which has completed the detection is pushed and unloaded one by one through the driving of the auxiliary ejection assembly 2 in the process of multiple sealing of the sealing assembly 1, the manual operation of moving and taking out the electronic device which has completed the detection is omitted, manpower is saved, the taking out operation efficiency is greatly improved, and the automatic pushing and taking out ensures that the electronic device is stably and accurately moved out, so that the risk of damage of the electronic device caused by improper manual moving operation is avoided.In the process of inflation sealing of the sealing assembly 1, the sealing assembly 1 synchronously triggers the opening assembly 3 to open the steam inlet 19 and the airflow inlet 20 alternately, that is, to ensure that the steam inlet 19 and the airflow inlet 20 are not opened at the same time, so that when the steam inlet 19 fills the inside of the detection box 5 with water vapor, the airflow inlet 20 is in a closed state, avoiding the escape of water vapor through the airflow inlet 20, causing waste of water vapor. At the same time, when the airflow inlet 20 inputs hot air into the inside of the detection box 5, the airflow inlet 20 is closed, avoiding the entry of hot air into the steam inlet 19. Through the staggered opening design of the steam inlet 19 and the airflow inlet 20, the loss of water vapor or heat is further reduced, and better switching of different test environments is assisted.

[0038] Further as shown in Figure 1 、 Figure 4 、 Figure 6 and Figure 8 , it is worth noting that the sealing assembly 1 includes two rubber frame strips 101 fixed in the two end ports of the detection box 5, respectively. The inside of the rubber frame strip 101 is provided with an inner cavity 102, and the two rubber frame strips 101 are connected with a liquid passage a 103. The two ends of the liquid passage a 103 are in communication with the inner cavities 102 in the two rubber frame strips 101, respectively. The middle of the liquid passage a 103 is communicated with a liquid cylinder a 104. The top surface of the detection box 5 is fixed with an electric telescopic rod 107, and the output end of the electric telescopic rod 107 is fixed with a piston plate a 105 which is tightly matched with the inner side wall of the liquid cylinder a 104. When the electronic device is moved into the inside of the detection box 5, at this time, the two partitions 7 are distributed in the two end ports of the detection box 5. The electric telescopic rod 107 is controlled to work by the PLC controller 8. The output end of the electric telescopic rod 107 drives the piston plate a 105 to move downward in the liquid cylinder a 104. The liquid cylinder a 104 is filled with a certain amount of liquid, which can be water or hydraulic oil, etc. Thus, the liquid in the liquid cylinder a 104 is synchronously squeezed into the inside of the two rubber frame strips 101 through the liquid passage a 103 by the piston plate a 105, so that the two rubber frame strips 101 are synchronously expanded, thereby expanding and plugging the gap between the partition 7 and the inner side wall of the port of the detection box 5 through the two synchronously expanded rubber frame strips 101, so that a relatively closed space is formed in the inside of the detection box 5, greatly reducing the loss of heat and water vapor, saving energy consumption, and at the same time ensuring the stability of the detection environment, improving the detection accuracy and reliability.

[0039] Further as shown in Figure 2 and Figure 7As shown, it is worth noting that the auxiliary outlet assembly 2 includes a liquid passage pipe b201 in communication with one of the rubber frame strips 101, and a liquid cylinder b202 is in communication with one end of the liquid passage pipe b201 away from the rubber frame strip 101, a push rod 205 is inserted into the liquid cylinder b202, a piston plate b204 is fixed on one end of the push rod 205 in the liquid cylinder b202, and a push plate 206 is fixed on the other end of the push rod 205 outside the liquid cylinder b202; when the electronic equipment in the detection box 5 is detected, the support plate 6 is driven by the adjusting assembly 4 to move forward by a certain displacement, so that the detected electronic equipment is moved out of the outlet of the detection box 5, and the next electronic equipment enters the detection box 5 for detection; when the rubber frame strip 101 has hydraulic expansion, part of the liquid in the rubber frame strip 101 is synchronously input into the liquid cylinder b202 through the liquid passage pipe b201 under the action of the hydraulic pressure, so that the liquid cylinder b202 has a certain hydraulic pressure, thereby the piston plate b204 is driven to move in the liquid cylinder b202 by the hydraulic pressure, the push rod 205 is driven to extend out of the liquid cylinder b202 by the piston plate b204, and then the detected electronic equipment between the two partitions 7 is automatically pushed out by the push plate 206, thereby the operation of manually moving and taking out the detected electronic equipment is saved, the manpower is saved, the taking-out operation efficiency is greatly improved, and the electronic equipment is stably and accurately moved out by automatic pushing and taking out, thereby the risk of equipment damage caused by improper manual moving operation is avoided.

[0040] Further as shown in Figure 7 , it is worth noting that the liquid cylinder b202 is provided with a reset spring a203, the reset spring a203 is located on the side of the piston plate b204 away from the push plate 206, and the two ends of the reset spring a203 are fixed with the piston plate b204 and the inner wall of the liquid cylinder b202; when the liquid in the rubber frame strip 101 is released, the hydraulic pressure in the liquid cylinder b202 is simultaneously released, and the piston plate b204 is pulled to reset by the reset spring a203, so that the push rod 205 is retracted into the liquid cylinder b202, thereby avoiding the blockage of the partitions 7 by the push rod 205 and the push plate 206, and forming the process of continuously pushing and discharging the detected electronic equipment by the push plate 206 in the process of sealing the rubber frame strip 101 multiple times.

[0041] Further as shown in Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, it is worth noting that the adjusting assembly 3 includes a liquid cylinder c307 fixed to the outer wall of the rubber frame strip 101 and communicating with the inner cavity 102. A connecting rod 305 is inserted into the liquid cylinder c307. A piston plate c306 that fits tightly against the inside of the liquid cylinder c307 is fixed to one end of the connecting rod 305 located inside the liquid cylinder c307. A sealing plate 301 located on the side of the steam inlet 19 and the airflow inlet 20 near the center of the detection box 5 is fixed to the other end of the connecting rod 305 located outside the liquid cylinder c307. The sealing plate 301 has an opening a302 on its side to open the steam inlet 19 and the airflow inlet 20. A rubber pad 304 is attached to the side of the sealing plate 301 near the inner wall of the detection box 5. The rubber pad 304 and the detection box 5 are connected to each other. The inner wall is in close contact with the rubber pad 304, and a through-hole b303 communicating with the through-hole a302 is opened on the side of the rubber pad 304. A return spring b308 is installed in the liquid cylinder c307. The return spring b308 is located on the side of the piston plate c306 away from the connecting rod 305, and the two ends of the return spring b308 are fixed to the piston plate c306 and the inner wall of the rubber frame strip 101, respectively. When water vapor needs to be delivered into the detection box 5, during the expansion and sealing process of the rubber frame strip 101, part of the liquid in the rubber frame strip 101 is simultaneously delivered into the liquid cylinder c307, so that the liquid cylinder c307 has a certain hydraulic pressure. The hydraulic pressure pushes the piston plate c306 to move in the liquid cylinder c307, and the piston plate c306 drives the connecting rod 305 from the liquid cylinder c307. The extension rod 305 moves the sealing plate 301 a certain distance. When the openings a302 and b303 coincide with the steam inlet 19, the sealing plate 301 and the rubber pad 304 seal the airflow inlet 20, ensuring that the steam inlet 19 and the airflow inlet 20 do not open simultaneously. This prevents water vapor from escaping through the airflow inlet 20 and being wasted when the steam inlet 19 fills the detection chamber 5 with steam. Simultaneously, when hot air needs to be supplied to the detection chamber 5, the PLC controller 8 controls the output of the electric telescopic rod 107 to continue driving the piston plate a105 downwards within the liquid cylinder a104, thereby increasing the hydraulic pressure and forcing more liquid into the liquid cylinder c. Within 307, the piston plate c306 moves a certain distance within the liquid cylinder c307, thereby driving the sealing plate 301 to continue moving a certain distance. At this time, the openings a302 and b303 coincide with the airflow inlet 20, and the airflow inlet 20 is open while the steam inlet 19 is closed. When hot air is introduced into the airflow inlet 20 and the detection box 5, hot air is prevented from entering the steam inlet 19. The staggered opening design of the steam inlet 19 and the airflow inlet 20 further reduces the loss of water vapor or heat. The rubber pad 304 improves the sealing performance of the steam inlet 19 and the airflow inlet 20, enhancing the sealing effect. When the hydraulic pressure inside the rubber frame strip 101 is removed, the reset spring b308 pulls the sealing plate 301 back to its original position.

[0042] Further as shown in Figure 1 , Figure 3 and Figure 4 , it is worth noting that the adjusting assembly 4 comprises a sliding groove 402 fixed on the top surface of the bottom plate 15 and arranged along the length direction of the bottom plate 15, the bottom end side surface of the support plate 6 is fixed with a sliding plate 401 matched with the sliding groove 402, the side surface of the sliding plate 401 is fixed with a rack plate 403 arranged along the length direction of the sliding plate 401, the top surface of the bottom plate 15 is fixed with a servo motor 404, the output end of the servo motor 404 is fixed with a driving gear 405 engaged with the sliding plate 401, the outer side wall of the detection box 5 is fixed with a PLC controller 8 electrically connected with the servo motor 404 and the electric telescopic rod 107; in specific work, the specific model of the PLC controller 8 can adopt DVP60S-50, the output end of the servo motor 404 is driven to rotate intermittently by the PLC controller 8, so as to drive the sliding plate 401 and the support plate 6 to move intermittently by a certain distance through the cooperation of the driving gear 405 and the rack plate 403, and a plurality of electronic devices are driven to move into the detection box 5 for detection.

[0043] The scheme has the following working process: the multiple electronic devices are respectively placed on the top side of the support plate 6 and are spaced in multiple groups of the partition plates 7, the output end of the servo motor 404 drives the driving gear 405 to intermittently rotate, thereby driving the sliding plate 401 and the support plate 6 to intermittently move a certain distance through the cooperation of the driving gear 405 and the rack plate 403, and the multiple electronic devices are spaced and moved into the detection box 5 for detection, when a single electronic device is moved into the inside of the detection box 5, the cover plate 18 is opened, the power connection head at the end of the connecting wire is inserted into the plug interface of the electronic device through the slot 17, thereby the voltmeter 16 can first detect the voltage condition of the electronic device in the normal state, after the normal state detection is completed, the electric water heater inside the water tank 10 is started to work, the electric water heater generates water vapor after heating the water in the water tank 10, the water vapor is introduced into the inside of the detection box 5 through the gas conveying pipe 12, after a certain time, when the inside of the detection box 5 is basically filled with water vapor, the output end of the electric telescopic rod 107 drives the piston plate a 105 to move downward in the liquid cylinder a 104, thereby the liquid in the liquid cylinder a 104 is synchronously squeezed into the inside of the two rubber frame strips 101 through the liquid conveying pipe a 103 by the piston plate a 105, so that the two rubber frame strips 101 synchronously expand, thereby the gap between the partition plate 7 and the inner side wall of the port of the detection box 5 is expanded and blocked by the two synchronously expanded rubber frame strips 101, so that a relatively closed space is formed in the inside of the detection box 5, the humidity environment in the detection box 5 is stabilized, the voltage condition of the electronic device under the condition of high humidity can be detected, the output end of the electric telescopic rod 107 drives the piston plate a 105 to move upward in the liquid cylinder a 104, the expansion sealing of the rubber frame strip 101 is released, the hot air is conveyed into the inside of the detection box 5 by the air heater 9, the gas in the inside of the detection box 5 is discharged by the hot air flow, the port of the detection box 5 can be sealed by the rubber frame strip 101, the inside of the detection box 5 is heated by the hot air, thereby the voltage condition of the electronic device under the condition of high temperature can be detected, the port of the detection box 5 can also be sealed by the rubber frame strip 101, a certain amount of gas is input into the relatively closed detection box 5 by the air heater 9, the gas pressure in the inside of the detection box 5 is increased, so that the inside of the detection box 5 has a certain gas pressure, thereby the voltage condition of the electronic device under the condition of a certain gas pressure can be detected, so that multiple environments can be simulated to comprehensively test the electronic device;

[0044] When the electronic device in the detection box 5 is detected, the support plate 6 is driven to move forward by the servo motor 404, so that the detected electronic device is moved out of the outlet of the detection box 5 and moves to the push plate 206, and the next electronic device enters the detection box 5 for detection. When the rubber frame strip 101 expands again, part of the liquid in the rubber frame strip 101 is synchronously input into the liquid cylinder b202 through the liquid pipe b201, so that the liquid cylinder b202 has a certain hydraulic pressure inside. The piston plate b204 is driven to move in the liquid cylinder b202 by the hydraulic pressure, the push rod 205 is driven to extend out of the liquid cylinder b202 by the piston plate b204, and then the push plate 206 is driven by the push rod 205 to automatically push the detected electronic device between the two partitions 7 out of the inclined slide plate 13 for unloading. When the liquid pressure in the rubber frame strip 101 and the liquid cylinder b202 is released, the reset spring a203 is arranged to pull the piston plate b204 to reset, so that the push rod 205 is automatically reset and retracted into the liquid cylinder b202, avoiding affecting the normal movement of the partition 7.

[0045] When it is necessary to deliver water vapor into the detection box 5, part of the liquid in the rubber frame strip 101 is synchronously delivered into the liquid cylinder c307 during the expansion and sealing of the rubber frame strip 101, so that the liquid cylinder c307 has a certain hydraulic pressure inside. The piston plate c306 is driven to move in the liquid cylinder c307 by the hydraulic pressure, the connecting rod 305 is driven to extend out of the liquid cylinder c307 by the piston plate c306, and then the connecting rod 305 drives the sealing plate 301 to move a certain distance. At this time, the through hole a302, the through hole b303 and the steam inlet 19 coincide. At this time, the steam inlet 19 is opened, and the airflow inlet 20 is closed by the sealing plate 301 and the rubber pad 304, so that the airflow inlet 20 is in a closed state when the steam inlet 19 fills the water vapor into the detection box 5, avoiding the loss of water vapor through the airflow inlet 20.

[0046] Further as shown in Figure 7 It is worth noting that the outer side wall of the detection box 5 is fixed with a support plate a207, the liquid pipe b201 passes through the support plate a207 and is fixed with the support plate a207, the top surface of the bottom plate 15 is fixed with a support plate b208, and the liquid cylinder b202 is fixed to the top end of the support plate b208. During operation, the support plate a207 and the support plate b208 are arranged to stably support the liquid pipe b201 and the liquid cylinder b202 respectively.

[0047] Further as shown in Figure 1As shown, it is worth noting that the outlet side of the detection box 5 is provided with an inclined sliding plate 13, and the top surface of the inclined sliding plate 13 is connected with a plurality of equidistantly distributed rolling balls 14. In specific work, the electronic device is pushed onto the inclined sliding plate 13 through the push rod 205 and the push plate 206, so that the electronic device is slid off through the inclined sliding plate 13, and the frictional resistance of the electronic device sliding on the inclined sliding plate 13 is reduced through the plurality of rolling balls 14.

[0048] In summary: the gap between the two partitions 7 and the two ports of the detection box 5 is expanded and sealed by the sealing assembly 1, so that the inside of the detection box 5 forms a relatively closed space, greatly reducing the leakage and waste of water vapor, reducing energy consumption, while maintaining the stability of the humidity in the detection box 5, so that the detection process is not disturbed by the outside, so that the voltage condition of the electronic device under the condition of high humidity can be more accurately detected, effectively improving the accuracy and reliability of the detection; when the sealing assembly 1 expands to seal the port of the detection box 5, the sealing assembly 1 triggers the auxiliary outlet assembly 2 to automatically push out the electronic device that has completed the detection from the detection box 5. In the process of sealing multiple times by the sealing assembly 1, the auxiliary outlet assembly 2 is continuously driven to push out the detected electronic devices one by one, saving the manual operation of moving and taking out the detected electronic devices, saving manpower, greatly improving the efficiency of the taking-out operation, and at the same time, the automatic pushing and taking out ensure that the electronic device is moved out smoothly and accurately, avoiding the risk of damage to the equipment caused by improper manual moving operation; during the expansion and sealing process of the sealing assembly 1, the sealing assembly 1 synchronously triggers the opening and closing assembly 3 to open and close the steam inlet 19 and the airflow inlet 20, that is, to ensure that the steam inlet 19 and the airflow inlet 20 are not opened at the same time, so that when the steam inlet 19 fills the water vapor into the inside of the detection box 5, the airflow inlet 20 is in a closed state, avoiding the escape of water vapor through the airflow inlet 20, causing waste of water vapor, and at the same time, when the airflow inlet 20 inputs hot air into the inside of the detection box 5, the airflow inlet 20 is closed, avoiding the hot air into the steam inlet 19. Through the staggered opening design of the steam inlet 19 and the airflow inlet 20, the loss of water vapor or heat is further reduced; through the setting of the displacement assembly 4, a plurality of electronic devices are intermittently moved into the inside of the detection box 5 for orderly detection one by one, effectively improving the continuity of electronic device detection, greatly improving the overall detection efficiency, reducing the error of manual operation, and reducing the labor workload during the detection process.
