[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Please refer to Figure 1-4 A camera module test placement tool is provided, which includes a bottom plate 1, on which a plurality of mold bases 2 distributed in a matrix are fixedly installed, the mold base 2 is arranged in four in both the longitudinal and transverse directions, a positioning groove 3 is arranged on the mold base 2, the size of the positioning groove 3 matches the bottom of the camera module 4, the positioning groove 3 is used to position and place the camera module 4, a circuit board 5 is arranged on one side of the mold base 2, the circuit board 5 is electrically connected to the test system, an indicator light 6 is installed on the circuit board 5, after the test system completes the test on the camera module 4, the test result is displayed through the indicator light 6, the indicator light 6 is an LED light and is arranged in three, The colors of the three indicator lights 6 are yellow, red and green respectively. Yellow indicates that the camera module 4 is performing a test, green indicates that the test result of the camera module 4 is qualified, and red indicates that the test result of the camera module 4 is unqualified. In order to fix the camera module 4, a fixing structure is also arranged on the base plate 1. The fixing structure includes a positioning block 7 and a positioning strip 8. The positioning block 7 is fixedly connected to the base plate 1. The positioning strip 8 is provided with a limiting groove 9 matching the camera module 4.

[0037] On the multi-station inspection machine for camera modules, multiple camera module 4 test software is required. Due to the high requirements of the test software on computer hardware and the limitation of window space, the number of module test software running on one host is limited and needs to be distributed on multiple computers. In this example, four test hosts are required for the sixteen stations. Each host can run four module test software at the same time. As a result, if you want to understand the module detection status, you need to switch back and forth between four computers, which causes great trouble to the operator. For this reason, the mold bases 2 in a horizontal row can be used as a test group, and sixteen rectangular frames can be drawn on the display screen of a host, such as Figure 5 As shown, the number of the corresponding module is set in the rectangular box, and. In the display screen, each rectangular box corresponds to a mold base 2, and the display screens of the rectangular boxes are blank, yellow, green, and red, respectively. Among them, blank means that there is no module in the station, yellow means that the station module is in a lit state and is performing a test, green means that the station module is closed and the test result passes, and red means that the station module is closed and the test result fails. The text in the middle is the test item being executed, which will be updated in real time with the execution of the test software, and the test result will be transmitted to the circuit board 5 and displayed by the indicator light 6. When it is necessary to view the detailed information of one of the modules, just click on the rectangular box corresponding to the module. This part is software development, and no feature protection is performed here. It is just used to illustrate the test environment applied to the test placement tooling in this application.
