Description

Technical Field

[0001] The utility model relates to a test tool for an infrared laser illumination product with a lens zoom function, in particular to a test component for an infrared laser illumination module. Background Art

[0002] When an infrared laser illumination product with a lens zoom function is in use, the lens assembly is often pushed and pulled to facilitate focusing. In order to ensure smooth pushing and pulling of the lens, it is necessary to conduct necessary aging tests on this pushing and pulling action. The existing test methods mainly rely on manual assembly one by one and then power-on testing. This not only has low efficiency, but also the number of times the lens assembly is pushed and pulled is insufficient, and potential problems cannot be excluded. The core components, the motor and the optocoupler board, cannot be effectively verified, and thus defective products cannot be screened out in advance. Summary of the Utility Model

[0003] The utility model aims to overcome the shortcomings of the prior art and provides a test component for an infrared laser illumination module, which can efficiently test whether the pushing and pulling action of the lens assembly is smooth, screen out defective products in advance, reduce rework and improve the first-pass yield of the product.

[0004] A test component for an infrared laser illumination module includes: a plurality of lens assemblies, a plurality of PCBA boards integrated with LED lights, a power supply, and a switch control board; wherein, the number of the PCBA boards corresponds to the number of the lens assemblies one by one, and one PCBA board and one lens assembly form a group. The PCBA board and the lens assembly are electrically connected through a motor wire and an optocoupler wire; the power supply is used to supply power to each PCBA board; each PCBA board is electrically connected to the switch control board; the switch control board is used to drive any one or more of the PCBA boards to work and make the lens assembly corresponding to the PCBA board start the pushing and pulling action.

[0005] Optionally, a buzzer is further integrated on each PCBA board.

[0006] Optionally, a key is integrated on the switch control board, and the key is used to drive any one or more PCBA boards to work.

[0007] Optionally, an optocoupler socket and a motor socket are arranged on each PCBA board; the optocoupler socket is used for adaptively connecting with the optocoupler wire, and the motor socket is used for adaptively connecting with the motor wire.

[0008] Optionally, the power supply provides a voltage of 12V.

[0009] Optionally, after the lens assembly starts the pushing and pulling action, the pushing and pulling action will last for a preset time and automatically stop after the preset time.

[0010] Optionally, when the push - pull action of the lens assembly is abnormal, the LED lamp and buzzer on the PCBA board corresponding to the lens assembly will give a warning reminder.

[0011] An infrared laser illumination module test assembly provided by the present utility model can flexibly start the push - pull action of a single lens assembly or multiple lens assemblies through a switch control board for aging test; and give an alarm through an LED lamp or a buzzer after the test or when there is a test abnormality, thereby accurately positioning the corresponding abnormal lens assembly and notifying the tester to promptly discover defective products. Compared with the prior art, it can greatly save the labor test cost, efficiently verify the core materials, namely the motor and the optocoupler board, reduce rework and improve the first - pass rate of the product. Brief Description of the Drawings

[0012] Figure 1 It is a schematic structural diagram of the infrared laser illumination module test assembly in the embodiment of the present utility model. Detailed Embodiment

[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0014] Provide an infrared laser illumination module test assembly, as Figure 1 shown, including multiple lens assemblies, multiple PCBA boards integrated with LED lamps, a power supply, and a switch control board. The number of PCBA boards corresponds one - to - one with the number of lens assemblies, and taking one PCBA board and one lens assembly as a group, the PCBA board and the lens assembly are electrically connected through a motor wire and an optocoupler wire; the power supply is used to supply power to each PCBA board; each PCBA board is electrically connected to the switch control board; the switch control board is used to drive any one or more PCBA boards to work and make the lens assembly corresponding to the PCBA board start the push - pull action.

[0015] Among them, the power supply is preferably 12V. The motor wire is used to test the motor in the lens assembly. The optocoupler wire is used to test the optocoupler board in the lens assembly. The switch control board is integrated with buttons, and through the buttons, any one or more PCBA boards can be driven to work, and then the corresponding lens assembly can be started to perform the push - pull action. It can be understood that the operation for users is not limited to buttons. The LED lamp is used to prompt the test result of the push - pull action. For example, green represents passing the test, and red represents an abnormal state.

[0016] Furthermore, each PCBA board is also integrated with a buzzer; when the lens push - pull is abnormal, the buzzer on the corresponding PCBA board will give an alarm to remind the tester.

[0017] Furthermore, an optocoupler socket port and a motor socket port are provided on each PCBA board; the optocoupler socket port is used for adaptively connecting with an optocoupler wire, and the motor socket port is used for adaptively connecting with a motor wire. Compared with the simple way of flying wire soldering, the optocoupler socket port and the motor socket port are more convenient for testers to plug and unplug the wires during use.

[0018] Specifically, the tester can turn on the test of a single or all lens assemblies with one key through the switch control board. The pushing and pulling action will last for a preset time, such as 24 hours or shorter or longer, and will automatically stop after the preset time. When the lens assembly is being pushed and pulled normally, the LED light flashes green; when the normal pushing and pulling of the lens assembly ends, the LED light stays on green; when the lens assembly is abnormal, the LED light stays on red. At the same time, if a buzzer is integrated on the PCBA board, the buzzer will give an alarm.

[0019] The above is an elaboration on the test component of the infrared laser illumination module of the present utility model, which is used to help understand the present utility model; however, the implementation mode of the present utility model is not limited by the above embodiments. Any changes, modifications, substitutions, combinations, and simplifications made without departing from the principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
