However, when a charger fails the test, the device is not convenient to separate the unqualified charger from the qualified charger in a timely manner. It also requires staff to select them separately, which has limitations and reduces the efficiency of charger withstand voltage testing. Utility Model Content

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, this utility model provides a charger withstand voltage test device, including a main frame 1 and a side frame 2 fixedly disposed on one side of the main frame 1. The top of the main frame 1 and the side frame 2 are respectively provided with a first small conveyor 3 and a second small conveyor 5, and the second small conveyor 5 is disposed at the bottom of the first small conveyor 3. A slide plate 8 is fixedly disposed on one side of the top of the side frame 2, and the slide plate 8 is disposed at the bottom of the first small conveyor 3 and at the top of the second small conveyor 5. A support plate 9 is fixedly disposed at the bottom of both the main frame 1 and the side frame 2 to facilitate support of the main frame 1 and the side frame 2.

[0025] like Figure 1-4 As shown, a test assembly 7 is provided between the front and rear side walls of the main frame 1, and the test assembly 7 is located on the top of the first small conveyor 3 for performing a pressure resistance test on the charger body 11. Several evenly distributed U-shaped rubber rods 4 are fixed on the surface of the first small conveyor 3. The test assembly 7 includes two electric telescopic rods 71, which are respectively fixed on the inner walls of the front and rear sides of the main frame 1. The ends of the two electric telescopic rods 71 ​​that are close to each other are respectively fixed with pressure plates 72 and plug plates 75 distributed in the front and rear.

[0026] An insulating block 73 is fixedly provided on the rear side of the pressure plate 72. A second photoelectric switch 74 is embedded at one end of the rear side of the pressure plate 72 near the side frame 2. The charger body 11 is located between the pressure plate 72 and the power strip 75, which facilitates the detection of the presence of the charger body 11 by the second photoelectric switch 74. A battery storage box 77 is fixedly provided on the rear side wall of the main frame 1. The input end of the power strip 75 is connected to the battery storage box 77 through a wire 76, and the wire 76 passes through the rear side wall of the main frame 1, which facilitates the withstand voltage test of the charger body 11. A control panel 10 is fixedly provided on the front side of the main frame 1 for controlling the operation of the first small conveyor 3, the second small conveyor 5, the second photoelectric switch 74, and the electric telescopic rod 71.

[0027] When a withstand voltage test is required on the charger body 11 by setting up test component 7, firstly, the control panel 10 is operated to drive the first small conveyor 3, the second small conveyor 5, and the second through-beam photoelectric switch 74. Then, the charger body 11 is placed on top of the first small conveyor 3 and snapped into the center of the U-shaped rubber rod 4. The first small conveyor 3 drives the charger body 11 to move. When it passes the second through-beam photoelectric switch 74, the second through-beam photoelectric switch 74 detects the position of the charger body 11 and sends a signal to the control panel 10, causing the control panel to... 10 controls the first small conveyor 3 to stop conveying and drives the two electric telescopic rods 71 ​​to work. The electric telescopic rod 71 on the front side drives the pressure plate 72 to move, causing the insulating block 73 to contact the output end of the charger body 11. The electric telescopic rod 71 on the rear side drives the socket plate 75 to move, so that the input end of the charger body 11 is inserted into the socket plate 75. At the same time, the storage box 77 supplies power to the charger body 11 through the wire 76, thereby realizing the withstand voltage test of the charger body 11. This facilitates the automatic withstand voltage test of several charger bodies 11 and improves the efficiency of withstand voltage test.

[0028] like Figure 1-3As shown in Figure 5, the second small conveyor 5 is equipped with a pushing assembly 6 at its top, which is used to collect charger bodies 11 that fail the withstand voltage test. The pushing assembly 6 includes a pushing plate 61, which is located on the rear wall inside the side frame 2 and on the top of the second small conveyor 5. An electric push rod 62 is fixedly installed on the rear side of the side frame 2. The piston rod of the electric push rod 62 passes through the rear side of the side frame 2 and is fixedly connected to the rear side of the pushing plate 61. The charger body 11 is located on the top of the first small conveyor 3. A first through-beam photoelectric switch 63 is embedded in the bottom front side of the pushing plate 61. An opening 64 is opened on the front side of the side frame 2, and the opening 64 corresponds to the pushing plate 61. A snap-fit ​​rod 65 is fixedly installed on the front side of the side frame 2. A sliding frame 66 is movably snapped onto the snap-fit ​​rod 65, and the sliding frame 66 is located in front of the opening 64 to facilitate the collection of charger bodies 11 that fail the withstand voltage test. The electric push rod 62 and the first through-beam photoelectric switch 63 are both controlled by the testing assembly 7.

[0029] By setting the pusher component 6, when the qualified charger body 11 has completely passed the second photoelectric switch 74, the second photoelectric switch 74 will transmit a signal to the control panel 10. The control panel 10 will send a signal to the first photoelectric switch 63 and drive the first small conveyor 3 to continue working, so as to transport the charger body 11. It will fall onto the top of the second small conveyor 5 via the slide plate 8 for transport again.

[0030] When the charger body 11 passes the first photoelectric switch 63, the first photoelectric switch 63 sends a signal to the control panel 10, causing the control panel 10 to continue controlling the second small conveyor 5 to transport the qualified charger body 11 and collect it from one end of the second small conveyor 5. For charger bodies 11 that fail the withstand voltage test, the first photoelectric switch 63 sends a signal to the control panel 10, causing the control panel 10 to control the second small conveyor 5 to stop transporting and control the electric push rod 62 to drive the pusher plate 61 forward and push the unqualified charger body 11 into the slide frame 66 for centralized collection. This achieves the classification and collection of several charger bodies 11 after the withstand voltage test, thereby improving the withstand voltage test efficiency of the charger body 11 and reducing the labor intensity of the staff.

[0031] Both the first pair-beam photoelectric switch 63 and the second pair-beam photoelectric switch 74 are composed of a laser emitter and a photoelectric receiver. Their working principle is the same: when the charger 11 enters the optical path between the photoelectric receiver and the laser emitter, it will block the light beam, causing the photoelectric receiver to be unable to receive the light signal, which indicates that the charger 11 has been detected. Conversely, when the light beam is received by the photoelectric receiver again, it indicates that the charger 11 has not been detected.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
