[0013] Preferably, a control console is provided on one side of the test base, and a display is provided on the side of the control console close to the power adapter to be tested. The control console is electrically connected to the Z-axis electric push rod, the X-axis electric push rod, the proximity sensor and the drive motor, and the proximity sensor is provided at the bottom of the limit pressure plate.

[0014] A testing method for a power adapter life test device comprises the following steps:

[0015] Step 1: Preparation work, pre-set the control program of the drive motor through the console to make the drive motor perform equidistant intermittent motion. The interval distance is the distance between the three positioning pieces, that is, the distance between adjacent power adapters to be tested. Then start the trial run, and place the power adapters to be tested in turn between the positioning pieces evenly set on the outside of the transmission chain. Support the two sides of the power adapter to be tested with the positioning plates in the positioning pieces, and separate the adjacent power adapters to be tested with equal intervals through partitions. When the drive motor is started, the active sprocket drives the driven sprocket to rotate intermittently through the transmission chain under the drive of the drive motor, and then the transmission chain drives the power adapter to be tested to transmit at equal intervals through the positioning pieces. When the power adapter to be tested is transported to the bottom of the Z-axis electric push rod, the transmission stops. At this time, the Z-axis electric push rod is controlled by the console to push the sleeve downward. When the limit pressure plate on one side of the sliding sleeve is located at the top of the power adapter to be tested, the top of the power adapter to be tested is sensed by the proximity sensor at the bottom of the limit pressure plate. When the limit pressure plate is located at the set position, the console controls the Z-axis electric push rod to stop working. At this time, the plug-in mechanism on the inner side of the sliding sleeve is located on one side of the power adapter to be tested and is located at the same horizontal plane as the socket of the power adapter to be tested. Then, the plug-in mechanism and the socket of the power adapter to be tested are calibrated. During calibration, the screw on one side of the slide table is rotated by the rotating part, so that the screw pushes the slider to slide on the inner side of the slide table, and then the slider drives the Z-axis electric push rod to move. When the sliding sleeve at the output end of the Z-axis electric push rod is facing the socket of the power adapter to be tested, the adjustment is stopped, so that the plug-in mechanism is directly at the socket of the power adapter to be tested, and then the control program of the Z-axis electric push rod and the plug-in mechanism is set;

[0016] Step 2: Start the test, by placing the power adapter to be tested between the positioning pieces in sequence, so that the power adapter to be tested is transmitted intermittently and equidistantly under the transmission of the transmission chain. During the transmission process of the positioning piece, the positioning plate in the positioning piece slides on the top of the support table through the protrusion. The top of the support table is provided with a slide groove corresponding to the protrusion to ensure the stability of the positioning piece during horizontal transmission, and the protrusion first slides on the inside of the guide groove before entering the inside of the slide groove, and finally enters the inside of the slide groove with the guidance of the guide groove to ensure that several positioning pieces can slide on the top of the support table. Whenever the transmission chain stops, the Z-axis electric push rod will push the sliding sleeve downward, and the sliding sleeve will drive the connecting frame on the outside of the sliding rod when moving. The slide rod slides sideways, and then ensures the stability of the slide sleeve through the slide rod. When the limit pressure plate on one side of the slide sleeve senses the power adapter to be tested through the proximity sensor, it stops moving down, and then the X-axis electric push rod in the plug-in and pull-out mechanism pushes the plug to slide on the inner side of the slide sleeve, and the limit rods symmetrically fixedly connected on one side of the plug are all slidably connected to the slide sleeve to ensure the stability of the plug. With the push of the X-axis electric push rod, the plug is finally inserted into the socket on one side of the power adapter to be tested. After the power adapter to be tested is tested, the test result will be displayed on the display on one side of the console, so as to observe the test result of the power adapter to be tested, and then the plug is pulled out again under the action of the X-axis electric push rod, and the Z-axis electric push rod is reset;

[0017] Step 3: Unloading. The tested power adapters are continuously conveyed at equal intervals under the action of the transmission chain, so that the next group of power adapters to be tested enters the test area. The tested power adapters can be sorted out through the test results displayed on the display, and unqualified products can be sorted out, which improves efficiency while ensuring strict control of the power adapters to be tested.

[0018] Compared with the prior art, the present invention provides a device and method for testing the life of a power adapter, which have the following beneficial effects:

[0019] 1. The present invention sets a transmission chain so that the active sprocket drives the driven sprocket to rotate intermittently through the transmission chain, and then the transmission chain drives the power adapter to be tested to transmit at equal intervals through the positioning member. When the power adapter to be tested is transported to the bottom of the Z-axis electric push rod, the transmission is stopped, so that the Z-axis electric push rod pushes the sliding sleeve to move downward, and the sliding sleeve stops moving downward when the limit pressure plate on one side of the sliding sleeve is located at a specified height above the power adapter to be tested. Then, the power adapter to be tested is connected to the test system through the plug-in mechanism, and the power adapter to be tested is disconnected through the plug-in mechanism after the power adapter to be tested is tested, thereby replacing the traditional manual repeated plug-in and unplugging. In addition, the power adapter to be tested does not need to be repeatedly picked up and placed during the entire test process, thereby reducing the damage to the power adapter to be tested caused by human beings.

[0020] 2. The present invention sets a plug-in and pull-out mechanism so that the X-axis electric push rod in the plug-in and pull-out mechanism pushes the plug to slide on the inner side of the sliding sleeve, and the limit rods symmetrically fixedly connected on one side of the plug are all slidably connected with the sliding sleeve, thereby ensuring the stability of the plug. With the push of the X-axis electric push rod, the plug is finally inserted into the socket on one side of the power adapter to be tested. After the power adapter to be tested is tested, the plug is pulled out again under the action of the X-axis electric push rod, thereby achieving the effect of replacing repeated manual plug-in and pull-out.

[0021] 3. The present invention sets a support table, and the positioning plate in the positioning piece slides on the top of the support table through the protrusion. A sliding groove is provided on the top of the support table corresponding to the protrusion to ensure the stability of the positioning piece during horizontal transmission, and before the protrusion enters the inner side of the sliding groove, it first slides on the inner side of the guide groove, and finally enters the inner side of the sliding groove with the guidance of the guide groove, so as to ensure that several positioning pieces can slide on the top of the support table.

[0043] A testing method for a power adapter life test device comprises the following steps:

[0044] Step 1: Preparation work, pre-set the control program of the drive motor 31 through the control console 32, so that the drive motor 31 performs equidistant intermittent motion, and the interval distance is the distance between the three positioning members 5, that is, the distance between adjacent power adapters 6 to be tested, and then start the trial run, and place the power adapters 6 to be tested in turn between the positioning members 5 evenly arranged on the outside of the transmission chain 4, and support the two sides of the power adapter 6 to be tested through the positioning plates 12 in the positioning members 5, and separate the adjacent power adapters to be tested 6 at equal intervals through the partitions 14. When the drive motor 31 is started, the active sprocket 2 drives the driven sprocket 3 to rotate intermittently through the transmission chain 4 under the drive of the drive motor 31, and then the transmission chain 4 drives the power adapter 6 to be tested to be transmitted at equal intervals through the positioning members 5. When the power adapter 6 to be tested is transported to the bottom of the Z-axis electric push rod 7, the transmission is stopped. At this time, the Z-axis electric push rod 7 is controlled by the control console 32 to push the sliding sleeve 8 to move downward. When the sliding sleeve When the limit pressure plate 10 on one side of 8 is located at the top of the power adapter 6 to be tested, the proximity sensor 29 at the bottom of the limit pressure plate 10 senses the top of the power adapter 6 to be tested. When the limit pressure plate 10 is located at the set position, the console 32 controls the Z-axis electric push rod 7 to stop working. At this time, the plug-in mechanism 9 on the inner side of the sliding sleeve 8 is located on one side of the power adapter 6 to be tested, and is located at the same horizontal plane as the socket of the power adapter 6 to be tested. Then, the plug-in mechanism 9 and the socket of the power adapter 6 to be tested are calibrated. During calibration, the screw 24 on one side of the slide table 22 is rotated by the rotating member 25, so that the screw 24 pushes the slider 23 to slide on the inner side of the slide table 22, and then the slider 23 drives the Z-axis electric push rod 7 to move. When the sliding sleeve 8 at the output end of the Z-axis electric push rod 7 is facing the socket of the power adapter 6 to be tested, the adjustment is stopped, so that the plug-in mechanism 9 is directly at the socket of the power adapter 6 to be tested, and then the control program of the Z-axis electric push rod 7 and the plug-in mechanism 9 is set;

[0045] Step 2: Start the test, by placing the power adapter 6 to be tested between the positioning members 5 in sequence, so that the power adapter 6 to be tested is transmitted intermittently at equal intervals under the transmission of the transmission chain 4. During the transmission process of the positioning member 5, the positioning plate 12 in the positioning member 5 slides on the top of the support table 11 through the protrusion 15. A slide groove 19 is provided on the top of the support table 11 corresponding to the protrusion 15 to ensure the stability of the positioning member 5 during horizontal transmission, and before entering the inner side of the slide groove 19, the protrusion 15 first slides on the inner side of the guide groove 20, and finally enters the inner side of the slide groove 19 with the guidance of the guide groove 20 to ensure that several positioning members 5 can slide on the top of the support table 11. Whenever the transmission chain 4 stops transmitting, the Z-axis electric push rod 7 will push the sliding sleeve 8 to move downward, and the sliding sleeve 8 will drive the connecting frame 28 on the sliding rod 27 when moving. The outer side slides, and then the stability of the sliding sleeve 8 is ensured by the sliding rod 27. When the limit pressure plate 10 on one side of the sliding sleeve 8 senses the power adapter 6 to be tested through the proximity sensor 29, it stops moving down, and then the X-axis electric push rod 18 in the plug-in and pull-out mechanism 9 pushes the plug 16 to slide on the inner side of the sliding sleeve 8, and the limit rods 17 symmetrically fixedly connected on one side of the plug 16 are all slidably connected to the sliding sleeve 8, ensuring the stability of the plug 16. With the push of the X-axis electric push rod 18, the plug 16 is finally inserted into the socket on one side of the power adapter 6 to be tested. After the power adapter 6 to be tested is tested, the test result will be displayed through the display 33 on one side of the console 32, so as to observe the test result of the power adapter 6 to be tested, and then the plug 16 is pulled out again under the action of the X-axis electric push rod 18, and the Z-axis electric push rod 7 is reset;

[0046] Step 3: unloading. The tested power adapters 6 continue to be transported at equal intervals under the action of the transmission chain 4, so that the next group of power adapters 6 to be tested enters the test area. The tested power adapters 6 can be sorted out through the test results displayed on the display 33, and unqualified products are sorted, thereby improving efficiency while ensuring strict control of the power adapters 6 to be tested.

[0047] The working principle and use process of the present invention are as follows: when in use, the control program of the driving motor 31 is pre-set through the control console 32, so that the driving motor 31 performs equidistant intermittent motion, and the interval distance is the distance between the three positioning members 5, that is, the distance between adjacent power adapters 6 to be tested, and then the trial operation is started, and the power adapters 6 to be tested are placed in sequence between the positioning members 5 evenly arranged on the outside of the transmission chain 4, and the two sides of the power adapter 6 to be tested are supported by the positioning plates 12 in the positioning members 5, and the adjacent power adapters to be tested 6 are evenly spaced apart by the partitions 14. When the driving motor 31 is started, the driving sprocket 2 drives the driven sprocket 3 to rotate intermittently through the transmission chain 4 under the drive of the driving motor 31, and then the transmission chain 4 drives the power adapter 6 to be tested to be transmitted at equal intervals through the positioning members 5. When the power adapter 6 to be tested is transported to the bottom of the Z-axis electric push rod 7, the transmission is stopped. At this time, the Z-axis electric push rod 7 is controlled by the control console 32 to push the sleeve 8 to move downward. When the limit pressure plate 10 on one side of the sliding sleeve 8 is located at the top of the power adapter 6 to be tested, the top of the power adapter 6 to be tested is sensed by the proximity sensor 29 at the bottom of the limit pressure plate 10. When the limit pressure plate 10 is located at the set position, the console 32 controls the Z-axis electric push rod 7 to stop working. At this time, the plug-in mechanism 9 on the inner side of the sliding sleeve 8 is located on one side of the power adapter 6 to be tested, and is located at the same horizontal plane as the socket of the power adapter 6 to be tested. Then, the plug-in mechanism 9 and the socket of the power adapter 6 to be tested are calibrated. During calibration, the screw 24 on one side of the slide table 22 is rotated by the rotating member 25, so that the screw 24 pushes the slider 23 to slide on the inner side of the slide table 22, and then the slider 23 drives the Z-axis electric push rod 7 to move. When the sliding sleeve 8 at the output end of the Z-axis electric push rod 7 is facing the socket of the power adapter 6 to be tested, the adjustment is stopped, so that the plug-in mechanism 9 is directly at the socket of the power adapter 6 to be tested, and then the control program of the Z-axis electric push rod 7 and the plug-in mechanism 9 is set;The test is started. The power adapter 6 to be tested is placed between the positioning members 5 in sequence, so that the power adapter 6 to be tested is transmitted intermittently and equidistantly under the transmission of the transmission chain 4. During the transmission process of the positioning member 5, the positioning plate 12 in the positioning member 5 slides on the top of the support platform 11 through the protrusion 15. A slide groove 19 is provided on the top of the support platform 11 corresponding to the protrusion 15 to ensure the stability of the positioning member 5 during horizontal transmission, and the protrusion 15 first slides on the inner side of the guide groove 20 before entering the inner side of the slide groove 19, and finally enters the inner side of the slide groove 19 with the guidance of the guide groove 20 to ensure that several positioning members 5 can slide on the top of the support platform 11. Whenever the transmission chain 4 stops transmitting, the Z-axis electric push rod 7 will push the sliding sleeve 8 to move downward. When the sliding sleeve 8 moves, it will drive the connecting frame 28 to slide on the outer side of the sliding rod 27, and then the stability of the sliding sleeve 8 is ensured by the sliding rod 27. When the limit pressure plate 10 on one side of the sliding sleeve 8 senses the power adapter 6 to be tested through the proximity sensor 29, it stops. The plug 16 is stopped from moving downward, and then the X-axis electric push rod 18 in the plug-in and pull-out mechanism 9 pushes the plug 16 to slide on the inner side of the sliding sleeve 8, and the limit rods 17 symmetrically fixedly connected on one side of the plug 16 are all slidably connected to the sliding sleeve 8, ensuring the stability of the plug 16. With the push of the X-axis electric push rod 18, the plug 16 is finally inserted into the socket on one side of the power adapter 6 to be tested. After the power adapter 6 to be tested is tested, the test result will be displayed on the display 33 on one side of the console 32, so as to observe the test result of the power adapter 6 to be tested. Then, under the action of the X-axis electric push rod 18, the plug 16 is pulled out again, and the Z-axis electric push rod 7 is reset; the power adapter 6 to be tested after the test continues to be transmitted at equal intervals under the action of the transmission chain 4, so that the next group of power adapters 6 to be tested enter the test area, and the power adapter 6 to be tested after the test can sort out unqualified products through the test results displayed on the display 33, while improving efficiency and ensuring strict control of the power adapter 6 to be tested. ;
