Technical Field

[0001] This application relates to the field of positioning mechanism technology, and in particular to a positioning mechanism for a charger function testing device. Background Technology

[0002] Currently, charger functional testing equipment is a specialized instrument used to comprehensively test charger performance. It primarily verifies whether inputs (voltage, current harmonics), outputs (voltage accuracy, current capability, power), conversion efficiency, and protection functions (overvoltage, overcurrent, short circuit, temperature protection) meet standards. Common equipment includes automated testing systems, protocol analyzers, load simulators, and safety testing instruments. The testing process covers static parameters, dynamic loads, fast charging protocol handshakes, and safety compliance. Application scenarios cover full production line inspection, R&D verification, and after-sales analysis, ensuring chargers are safe, compatible, and efficient, meeting industry standards, and reducing quality risks.

[0003] During charger production and testing, chargers typically need to be placed on testing machines for functional testing, such as input / output characteristics, protocol compatibility, and protection function testing. However, most existing testing equipment lacks efficient and precise positioning mechanisms, leading to issues such as charger misalignment and poor contact during testing, affecting the accuracy and consistency of test results. Furthermore, manually placing chargers is inefficient and cannot meet the high-speed requirements of automated production lines.

[0004] Therefore, there is an urgent need for a charger positioning mechanism that is simple in structure, accurate in positioning, and highly adaptable, in order to improve testing efficiency, ensure testing stability, and be compatible with chargers of different specifications. Utility Model Content

One end of the connecting rod is connected to the piston rod of the pressing cylinder, and the other end extends between the two positioning seats. A pressure rod is connected to the connecting rod, and a pressure head is provided on the pressure rod. The pressure head faces the side closer to the tray.

[0010] Furthermore, the pallet positioning assembly includes a sliding cylinder and a slider. The sliding cylinder drives the slider to slide on the frame. A push rod is rotatably mounted on the slider. The push rod rotates towards the side closer to the pallet. A positioning rod is provided on the pallet, and the push rod abuts against the positioning rod.

[0011] Furthermore, a positioning cylinder is provided on the frame, the positioning cylinder is mounted on the frame, a positioning pin is installed at one end of the piston rod of the positioning cylinder, a positioning hole is opened on the tray, and the positioning pin is inserted into the positioning hole.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] This application discloses a positioning mechanism for a charger function testing device.

[0019] Reference Figure 1 A positioning mechanism for a charger function testing device includes a frame 1, a tray 2 disposed on the frame 1, a product positioning component 3 disposed on the tray 2, the product positioning component 3 positioning the product, and a tray 2 positioning component disposed on the frame 1, the tray 2 positioning component positioning the tray 2.

[0020] Reference Figures 2-4 The product positioning component 3 includes positioning seats 31, which are arranged in pairs on the frame 1. The product to be tested is placed between the two positioning seats 31. In addition, a support plate 32 is provided on the side of the two sets of positioning seats 31 that are close to each other. The support plate 32 is integrally formed on the positioning seats 31. In use, the charger is placed on the support plate 32 of the two sets of positioning seats 31.

[0021] Reference Figure 4 To improve the adaptability of the positioning seat 31 to chargers of different sizes, a sliding groove 21 is provided on the tray 2. The two sets of positioning seats 31 slide along the length of the sliding groove 21 on the tray 2. To enhance the stability of the positioning seat 31 on the sliding groove 21, a positioning bolt 33 is provided on the positioning seat 31. One end of the positioning bolt 33 passes through the positioning seat 31 and the sliding groove 21, and a nut 331 is threadedly connected to the end of the positioning bolt 33 passing through the sliding groove 21. One end of the nut 331 abuts against the tray 2. This allows the spacing between the two sets of positioning seats 31 to be adjusted, enabling the positioning seat 31 to adapt to chargers of different sizes.

[0022] Reference Figure 3 In addition, a pressing cylinder 34 is installed on the frame 1. One end of the pressing cylinder 34 passes through the frame 1, and a connecting rod 341 is provided at the end of the pressing cylinder 34 that passes through the tray 2. The connecting rod 341 is arranged parallel to the tray 2, and one end of the connecting rod 341 is connected to the piston rod of the pressing cylinder 34. The other end extends horizontally between the two sets of positioning seats 31. A pressure rod 342 is provided at the end of the connecting rod 341 near the two sets of positioning seats 31. The pressure rod 342 is vertically arranged, and one end of the pressure rod 342 is connected to the connecting rod 341. The other end extends vertically towards the side of the tray 2. A pressure head 343 is provided at one end of the pressure rod 342 near the tray 2. The pressure head 343 is mounted on the pressure rod 342 and is made of rubber. When the charger is placed on the positioning seat 31, the pressing cylinder 34 presses the pressure head 343 against the charger through the connecting rod 341 and the pressure rod 342. The pressure head 343 deforms under pressure, thereby enabling the charger to be positioned on the positioning seat 31.

[0023] Furthermore, a sliding cylinder 35 is installed on the frame 1, horizontally mounted on the tray 2, and a slider 351 is installed on the sliding cylinder 35.

In use, the push rod 352 rotates towards the side closer to the push plate. In addition, a positioning rod 353 is installed on the tray 2, one end of which is connected to the tray 2. The push rod 352 and the positioning rod 353 are arranged parallel to each other. In use, the sliding cylinder 35 drives the slider 351 to slide on the frame 1, and the slider 351 is pressed against the positioning rod 353 by the push rod 352, thereby enabling the tray 2 to be stably mounted on the frame 1.

The inclined direction of the guide slope 23 faces the side closer to the positioning pin 411. In use, the positioning cylinder 41 drives the positioning pin 411 to insert into the positioning hole 22. During the insertion of the positioning pin 411 into the positioning cylinder 41, the guide slope 23 guides the positioning pin 411, thus improving the ease with which the positioning pin 411 is inserted into the positioning hole 22 of the pallet 2.

[0025] The positioning assembly of the pallet 2 includes a slide plate 42, which is slidably mounted on the frame 1. A support block 421 is provided on the slide plate 42. As the slide plate 42 slides on the frame 1, the support block 421 supports the pallet 2.

[0026] To improve the ease of sliding the slide plate 42 on the frame 1, a drive motor 43 and a screw 431 are installed on the frame 1. The screw 431 is rotatably mounted on the frame 1, and one end of the screw 431 passes through the slide plate 42, with the slide plate 42 and the screw 431 threadedly connected.
