Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a visual detection device for electronic component defects. Background Art

[0002] Circuit boards are a type of electronic component. After production, visual inspection devices are needed to test the quality of electronic components. The visual inspection devices can capture the appearance of the circuit boards to check whether there are any wear or defects on the surface of the circuit boards.

[0003] In order to improve the efficiency of visual inspection of electronic components, a conveyor belt is usually used. The electronic components to be inspected are placed one at a time from one end of the conveyor belt and the inspection camera at one end takes pictures of the electronic components for inspection.

[0004] Since the light from the detection lens is in a focused state during the shooting process, the shooting light can be focused to shoot the object more clearly. However, it is not convenient to position the electronic components during the loading process, and the placement of the electronic components is prone to offset, which makes it difficult for the shooting lens to shoot the electronic components well. At the same time, during shooting, the dust attached to the top of the electronic components is not cleaned well, which makes it easy for the dust to block the electronic components, affecting the shooting of the electronic components by the shooting lens, thereby reducing the accuracy of the shooting lens in shooting and storing the electronic components. In view of the shortcomings of the existing technology, we propose an electronic component defect visual detection device to solve the above problems. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The embodiment of the present application solves the problem of reducing the accuracy of the camera lens in photographing and storing electronic components by providing a visual inspection device for electronic component defects, thereby improving the clarity of the camera lens in photographing electronic components and improving the accuracy of electronic component inspection.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The embodiment of the utility model discloses a device for visually detecting defects of electronic components.

[0029] According to the attached Figure 1-5As shown, it includes a detection platform 1, a conveyor belt 101 is provided at the detection platform 1, a detection lens 2 is provided at the top of the conveyor belt 101, and limit plates 302 are installed at intervals at the top of the conveyor belt 101, and a cleaning roller 3 is provided on one side of the detection lens 2; when performing defect detection on the top of the electronic component, it is first necessary to position the electronic component to be detected between the two sets of limit plates 302, and then the conveyor belt 101 conveys the installed electronic component, and the dust on the top of the electronic component is cleaned by the cleaning roller 3 on one side, and then the electronic original conveyed to the bottom of the detection lens 2 is photographed and detected by the detection lens 2.

[0030] The cleaning roller 3 has the function of cleaning the dust on the top of the electronic component. The two sides of the limit plate 302 are slidably connected with the positioning plate 303. The interior of the limit plate 302 is provided with a driving unit. The driving unit has the function of driving the positioning plates 303 on both sides to approach each other to position the electronic components. When installing and positioning the electronic original, first adjust the positioning plates 303 at the multiple groups of limit plates 302 according to the width of the electronic component to be detected, so that the positioning plates 303 can position the electronic original in the middle of the conveyor belt 101, thereby facilitating the detection lens 2 to shoot and detect the electronic components.

[0031] Both sides of the top of the detection platform 1 are fixedly connected with the mounting side plates 301, and both ends of the cleaning roller 3 are located inside the mounting side plates 301. The cleaning roller 3 is made of soft fiber textile fabric and will not cause damage to electronic components during cleaning. The outer walls of both ends of the cleaning roller 3 are fixedly connected with the limiting blocks 3013, and the outer walls of the limiting blocks 3013 are fixedly connected with the mounting plates 3011. By rotating the rotating part 3025 on one side, the driving gear 3023 at one end is rotated to drive the tooth plates on both sides to approach each other, and then the mounting part 3024 on one side can drive the positioning plates 303 on both sides to approach each other, so as to quickly clamp and position the electronic components on both sides.

[0032] The bottom end of the mounting plate 3011 is fixedly connected to a driving spring 3012, and the bottom end of the driving spring 3012 is fixedly mounted on the top end surface of the detection platform 1. The driving unit includes:

[0033] The upper tooth plate 3021 and the lower tooth plate 3022 are slidably connected to the interior of the limiting plate 302;

[0034] The driving gear 3023 is rotatably connected between the upper tooth plate 3021 and the lower tooth plate 3022, and meshes with the upper tooth plate 3021 and the lower tooth plate 3022. When the clamped electronic component passes through the cleaning roller 3, the front end of the moving limit plate 302 first contacts the cleaning roller 3, and then generates a thrust on the cleaning roller 3 under the push of the electronic component, which can cause the driving springs 3012 on both sides to deform and drive the cleaning roller 3 to move up to the top of the electronic component, so that the bottom end of the cleaning roller 3 is in close contact with the upper surface of the electronic component to clean the dust on the top of the electronic component.

[0035] The upper and lower gear plates 3021 and 3022 are fixedly connected at one end thereof with a mounting part 3024 away from each other, and one end of the mounting part 3024 is fixedly connected to the outer wall of the positioning plate 303, and the position of the positioning plates 303 on both sides is regulated by the meshing between the driving gear 3023, the upper and lower gear plates 3021 and the lower gear plates 3022. One end of the driving gear 3023 is fixedly connected to a rotating part 3025, and the rotating part 3025 is located on one side outer wall of the limit plate 302. At the same time, it should be noted that the electronic component fibers are positioned between the two sets of limit plates 302. In the process of the conveyor belt 101 driving the electronic components to move and clean, the limit plates 302 on both sides can drive the electronic components to move without blocking the cleaning roller 3 to the moving electronic components, and can position the electronic components in the middle below the detection lens 2 through the positioning plates 303 on both sides, thereby avoiding the electronic components from being offset during the loading process, affecting the quality of the detection lens 2 in shooting and detecting the electronic components.
