During the high-voltage test, the first test mechanism and the second test mechanism are used to detect whether there is leakage on the surface of the hair dryer. Since the first test mechanism and the second test mechanism are both connected to the controller, the entire machine can have high-voltage test, wind blocking test and cooling test at the same time, which greatly improves the detection efficiency. In addition, the test has a high degree of automation, which greatly reduces the workload of the operator.

A spring 713 is provided between the conductive thimble 710 and the first pressing block 71. The setting of the spring 713 can make the conductive thimble 710 have a buffer-type fixed structure, thereby avoiding wear on the threaded hole of the hair dryer and also having a certain limiting effect on the hair dryer. The setting of the guide rod 711 and the guide sleeve 712 can achieve straightness of the conductive thimble 710 when it is adjusted up and down, ensuring that the conductive thimble 710 is inserted into the threaded hole of the hair dryer.

[0027] The frame 1 is provided with an adjusting mechanism 714 connected to the first pressing block 71, and the adjusting mechanism 714 includes a vertical cylinder 715 and a horizontal cylinder 716. The vertical cylinder 715 is fixedly connected to the frame 1, and the vertical cylinder 715 is provided with a mounting plate 717 for mounting the horizontal cylinder 716, and the horizontal cylinder 716 is provided with a connecting plate 718 connected to the first pressing block 71.

The position of the first pressing block 71 in the vertical direction is adjusted by the vertical cylinder 715, and the position of the first pressing block 71 in the horizontal direction is adjusted by the horizontal cylinder 716, thereby ensuring the accuracy of the position adjustment of the first pressing block 71 and ensuring the conductive top The needle 710 can be accurately inserted into the threaded hole of the hair dryer. Secondly, the setting of the mounting plate 717 can increase the contact area between the horizontal cylinder 716 and the vertical cylinder 715, ensuring the straightness of the installation of the horizontal cylinder 716. The connecting plate 718 can increase the contact area between the first pressure block 71 and the horizontal cylinder 716, and improve the fixing quality of the first pressure block 71.

[0028] The ejection mechanism 8 includes a lifting cylinder 81 and a ejection block 82 arranged on the lifting cylinder 81. The lifting cylinder 81 is connected to the controller 4. The ejection mechanism is arranged into a structure of a lifting cylinder 81 and an ejection block 82. Since the lifting cylinder 81 is connected to the controller 4, when the controller 4 determines that the tested hair dryer is an unqualified product, the controller 4 controls the lifting cylinder 81 to rise, thereby driving the ejection block 82 to eject the plug, thereby realizing automatic separation of the plug and the socket 5. Secondly, an ejection pin is provided on the ejection block 82. Since the socket 5 is provided with a through hole 50 for the ejection pin to penetrate, when the plug is ejected, the ejection pin passes through the through hole 50 and is externally placed on the socket 5. At this time, the plug cannot be normally inserted into the socket 5, and the operator needs to manually reset it, which further improves the safety performance. The top of the ejector pin is provided with an arc chamfer, and the ejector pin and the ejector block 82 are an integrated structure. Providing an arc chamfer on the top of the ejector pin can reduce stress concentration on the ejector pin and effectively increase the service life of the ejector pin. Secondly, providing the ejector pin and the ejector block 82 as an integrated structure can simplify the installation process between the ejector pin and the ejector block 82 and improve the connection strength between the ejector pin and the ejector block 82.

The alarm component 10 is set so that when the controller 4 determines that the hair dryer being tested is an unqualified product, the controller 4 can trigger the alarm component 10 to send an alarm signal. Specifically, the alarm component 10 is set to a buzzer 11 and an LED light 12, which can achieve a dual alarm of sound and light 12, which can improve the alarm effect. The frame 1 is provided with a reset switch 13, an emergency stop switch 14 and a power meter 15. The reset switch 13 is set to manually reset the equipment. The emergency stop switch 14 is set so that when any situation occurs during the test, the operator can press the emergency stop switch 14 to stop the machine urgently. The power meter 15 is set to display the voltage and current during the test in real time, which is convenient for the operator to read. The rack 1 is provided with a power cord 16 electrically connected to an external power supply, and a power switch 17 for controlling the conduction and port of the power cord 16. The power cord 16 is provided to provide power to the rack 1 through an external power supply. When the hair dryer plug is inserted into the socket 5, the hair dryer can be powered on. The power switch 17 is provided to disconnect the power supply in time after the test is completed, thereby improving safety performance.

[0030] When in use, connect the power cord 16 to the external power supply, put the hair dryer to be tested into the cavity 30, and insert the plug into the socket 5, then turn on the power switch 17 to power it on. After the controller 4 senses the current of the hair dryer, it starts the first rotary cylinder 61 to make the cover 63 block the air inlet of the hair dryer and perform a wind blocking test. If the automatic protection device of the hair dryer is turned on within the specified time, the controller 4 will detect it and determine that the hair dryer is a qualified product and control the cooling fan 32 to perform a cooling operation. If the automatic protection device of the product is not turned on within the specified time, the controller 4 determines that the product is unqualified, then the controller 4 starts the first rotary cylinder 61 to move the cover 63 out of the air inlet of the hair dryer, and then starts the cooling fan 32 to cool the hair dryer, and starts the ejection mechanism 8 to eject the plug from the socket 5 and controls the alarm component 10 to send an alarm signal, waiting for the operator to manually reset it. After the wind blocking is qualified, the power is cut off, and then the cooling fan 32 cools the hair dryer. If the protection device of the hair dryer is reset within the specified time, the controller 4 determines that the hair dryer is a qualified product and performs In the next step, if the automatic protection device of the hair dryer is not reset within the specified time, the controller 4 determines that the hair dryer is an unqualified product, starts the ejection mechanism 8 to eject the plug from the socket 5 and controls the alarm component 10 to send an alarm signal, waiting for the operator to manually reset it; after cooling is qualified, the cooling fan 32 stops operating, the controller 4 starts the first rotary cylinder 61, the adjustment mechanism 714 and the second rotary cylinder 721 to press the cover 63, the first pressure block 71 and the second pressure block 72 downward, and then opens the high-voltage tester 2 for high-voltage testing. If the high-voltage test is qualified, the controller 4 drives the first rotary cylinder 61, the adjustment mechanism 714 and the second rotary cylinder 721 respectively to reset the cover 63, the first pressure block 71 and the second pressure block 72, and then starts the ejection mechanism 8 to eject the plug and wait for the next round of testing. If the high-voltage test fails, the cover 63, the first pressure block 71 and the second pressure block 72 are reset, and the ejection mechanism 8 is started to eject the plug and controls the alarm component 10 to send an alarm signal, waiting for the operator to manually reset it. In addition, if there is any situation during the test, the test can be stopped urgently by the emergency stop button.
