Description

Technical Field

[0002] With the rapid development of the electric vehicle industry, the on-board charger (OBC), as a key component of electric vehicles, has a significant impact on the charging efficiency, safety, and user experience of electric vehicles due to its stability and reliability. The main function of the on-board charger is to convert alternating current (AC) into direct current (DC) required by the battery, and to control the charging power and efficiency during this process. Therefore, rigorous electrical performance testing of the on-board charger to ensure it meets design requirements is a crucial step in the electric vehicle production process.

[0003] Traditional on-board charger electromechanical performance testing relies heavily on manual operation, which is cumbersome and inefficient. Testers need to manually connect the testing equipment, set test parameters, record test results, and perform data analysis. This testing method is not only time-consuming and labor-intensive, but also susceptible to human factors, making it difficult to guarantee the accuracy and consistency of test results.

[0004] In summary, this utility model provides an automatic testing device for the electrical performance of a vehicle-mounted charger to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0016] like Figure 1-3 As shown, this utility model provides an automatic testing device for the electrical performance of a vehicle-mounted charger, including a controller 1 and a display 2. The display 2 is installed on the controller 1. A speed-multiplying chain 3 is set inside the controller 1. A carrier trolley 4 is placed on the speed-multiplying chain 3. A transfer robot 5 is set on one side of the speed-multiplying chain 3. The transfer robot 5 can be an existing identification transfer robot. A testing mechanism 6 is installed in conjunction with the transfer robot 5.

[0017] The carrier trolley 4 includes a carrier tray 41, a positioning pin 42, and a hand support bracket 43. The carrier tray 41 is equipped with a positioning pin 42 that cooperates with the workpiece. The positioning pin 42 is used to position and fix the workpiece. The carrier tray 41 is equipped with hand support brackets 43 on both sides. The carrier trolley 4 can be used to place the workpiece to be tested.

[0018] The testing mechanism 6 includes a product tray 61, telescopic cylinders 62, a platform positioning mechanism 63, a positioning block 64, a workpiece positioning platform 65, and a testing component 66. Two telescopic cylinders 62 are installed at the bottom of the product tray 61, and the two ends of the two telescopic cylinders 62 are respectively connected to the platform positioning mechanism 63. The positioning block 64 is installed on the outer side of the platform positioning mechanism 63 and mounted on the product tray 61. The workpiece positioning platform 65 is installed on the platform positioning mechanism 63, and the testing component 66 is equipped with telescopic cylinders.

[0019] The platform positioning mechanism 63 is slidably mounted on the product tray 61. The platform positioning mechanism 63 can slide left and right on the product tray 61 and clamp and position the platform.

[0020] Working principle: The controller 1 controls the operation of the double-speed chain 3. When the double-speed chain 3 is running, the carrier trolley 4 is placed on the double-speed chain 3. After the transfer robot 5 recognizes the carrier trolley 4, the transfer robot 5 transfers the carrier trolley 4 to the testing mechanism 6 and places it on the product tray 61. Then, the telescopic cylinder 62 is activated, so that the platform positioning mechanisms 63 on the left and right sides move closer to each other until the workpiece positioning platform 65 clamps and positions it. Then, the telescopic cylinder on the testing component 66 docks with the test workpiece to test the workpiece. After the test is completed, the transfer robot 5 places the tested workpiece back onto the double-speed chain 3 and transports it away.
