Description

Technical Field

[0001] The utility model relates to the technical field of AOI detection, in particular to an AOI testing device with a transmission function. Background Art

[0002] AOI testing device, namely automatic optical inspection equipment, is a device that uses optical principles to automatically inspect electronic products. In the PCB circuit board production process, the circuit boards need to be inspected for appearance quality before leaving the factory to prevent unqualified products from entering the market. However, manual inspection is inefficient, so AOI testing devices are needed to detect and identify various defects on PCB circuit boards, automatically record and analyze the inspection results, and provide strong data support for quality control in the production process.

[0003] Existing AOI testing devices usually require manual operation to place and take out PCB boards from the testing area, which increases the number of manual operation steps and time, thereby limiting overall production efficiency.

[0004] For example, the PCB board inspection device disclosed in the announcement number CN220584342U requires manual transmission operation when the PCB board is inspected, and does not have a transmission function. However, the integration of the AOI test device without a transmission function with the fully automated production line may be limited, which is not conducive to further automation and intelligence of the production process. In addition, the inspection device lacks the function of repeated inspection. For some complex or high-precision PCB circuit boards, one inspection may not be able to fully cover all defects and problems.

[0005] Therefore, it is necessary to invent an AOI testing device with a transmission function to solve the above problems. Utility Model Content

[0008] Preferably, there are multiple supporting feet and universal wheels, and the multiple supporting feet are arranged on one side of the universal wheel. The multiple supporting feet and the universal wheels are symmetrical with each other about the center of the frame, so that the supporting feet can ensure that the frame remains stable when stationary to prevent shaking or tipping, and the universal wheels enable the frame to be easily moved on various ground surfaces, greatly improving the maneuverability and flexibility.

[0009] Preferably, there are four storage trays, which are evenly distributed at equal distances. Storage slots are provided on the storage trays, so that the storage trays can be loaded with PCB circuit boards and provide a stable supporting platform for them, so that they are not easy to slide, fall or be damaged during movement on the conveyor belt.

[0010] Preferably, the No. 1 inspection cabinet and the No. 2 inspection cabinet are both arranged above the conveyor belt, and the No. 2 inspection cabinet is arranged on the right side of the No. 1 inspection cabinet, so that the conveyor belt can convey the PCB circuit board to the bottom of the No. 1 inspection cabinet and the No. 2 inspection cabinet for inspection.

[0011] Preferably, an X-ray detection mechanism is provided inside the No. 1 detection cabinet, and a CCD detector is provided below the X-ray detection mechanism, so that the X-ray detection mechanism generates and controls the emission of X-rays, and the CCD detector is responsible for receiving and converting these rays into visible images.

[0012] Preferably, a No. 1 fill light is arranged around the CCD detector, and a No. 1 control screen is arranged on the front outer wall of the No. 1 detection cabinet, so that the No. 1 fill light can provide necessary auxiliary light for the CCD detector to ensure that it can obtain clear and accurate image data.

[0013] Preferably, an AOI inspection mechanism is provided below the second inspection cabinet, and a CCD camera is provided below the AOI inspection mechanism, so that the AOI inspection mechanism uses the high-resolution camera and image processing algorithm of the CCD camera to capture, analyze and identify various defects on the PCB circuit board, such as solder joint short circuit, tin leakage, missing components, etc.

[0014] Preferably, a No. 2 fill light is arranged around the CCD camera, and a No. 2 control screen is arranged on the front outer wall of the No. 2 detection cabinet, so that the No. 2 fill light can supplement the light source in the environment, ensure the clarity and brightness of the image, and enable the CCD camera to capture more details, improve the contrast and dynamic range of the image, thereby making the picture more vivid and lively.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. Through the setting of the conveyor belt, the conveyor belt can realize the automatic transmission of PCB circuit boards, greatly improving the detection efficiency. Compared with manual operation, the conveyor belt can move PCB circuit boards more stably and quickly, reducing the time of manual handling. At the same time, the PCB circuit boards continuously enter the detection mechanism, thus realizing continuous production. This continuous production method helps to reduce the downtime in the production process and effectively improve production efficiency;

[0017] 2. Through the setting of X-ray inspection mechanism and AOI inspection mechanism, the PCB circuit board can be inspected twice by X-ray inspection mechanism and AOI inspection mechanism.
