Description

Technical Field

[0001] The utility model relates to an electrical component pin identification and detection component. Background Art

[0002] Prior art, such as the Chinese invention patent application document with publication number CN116840237A, discloses an IC pin defect detection device based on visual inspection. In this prior art, two secondary visual cameras are used to visually inspect vertical pins. This dual-camera approach is based on the fact that electrical components generally have two rows of vertical pins. In this case, using a single camera to capture and inspect from the side would cause pins to overlap due to the camera's angle, making it easy to misjudge and reduce the quality of the inspection. However, the installation of two cameras is costly, and further improvements to the prior art are needed. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention proposes an electrical component pin recognition and detection assembly that uses mirror projection and a single camera for detection.

[0004] An electrical component pin identification and detection assembly designed for this purpose includes a machine platform, a fixing assembly for fixing the electrical component is provided on the machine platform, a camera for identification is provided above the fixing assembly, mirrors are provided on the left and right sides of the fixing assembly, the mirrors are used to project the pins of the electrical component onto the mirror surface, and the cameras are used to capture the image of the pins in the mirror.

[0005] Preferably, the fixing assembly includes a fixing seat, and fixing blocks are respectively provided on the front and rear sides of the fixing seat, and the fixing blocks are provided with positioning grooves, and the positioning grooves are opened on one side toward the other positioning groove. The front and rear ends of the electrical component are respectively placed in the positioning grooves, and a hollow area is formed between the front and rear fixing blocks, and the mirror is located on the left and right sides of the hollow area.

[0006] Preferably, the mirror is arranged to be tilted gradually from bottom to top toward a side away from the hollow area.

[0007] Compared to existing technologies, this new method utilizes two mirrors to project vertically downward-pointing pins onto the mirrors. This allows a camera located above to quickly capture the images in both mirrors, allowing an external identification terminal to determine whether a pin is missing. The mirror reflections created by the two mirrors allow pins facing away from the cameras to be captured, facilitating identification and detection. The use of a single camera not only effectively reduces costs, but also, combined with the use of two mirrors, effectively ensures detection quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] See also Figure 1 and Figure 2 A pin identification and detection component for an electrical component includes a machine platform 10, a fixing component 20 for fixing an electrical component 40 is provided on the machine platform 10, a camera 30 for identification is provided above the fixing component 20, mirrors 240 are provided on the left and right sides of the fixing component 20, the mirrors 240 are used to project the pins of the electrical component 40 onto the mirror surface of the mirror 240, and the camera 30 is used to capture the image of the pins in the mirror 240.

[0012] In actual recognition detection, the camera is used to capture the image of the pin in the mirror 240 , and the external recognition terminal performs recognition based on the image captured by the camera 30 to determine whether the pin is missing.

[0013] See also Figure 2 The fixing assembly 20 includes a fixing base 210, and fixing blocks 220 are respectively provided on the front and rear sides of the fixing base 210. The fixing blocks 220 are provided with positioning grooves 221, and the positioning grooves 221 are opened on one side toward the other positioning groove 221. The front and rear ends of the electrical component 40 are respectively placed in the positioning grooves 221, and a hollow area 230 is formed between the front and rear fixing blocks 220. The mirror 240 is located on the left and right sides of the hollow area 230.

[0014] In actual use, the electrical component 40 is grasped by a robot arm or vacuum nozzle and placed in the positioning slots 221 of the front and rear fixing blocks 220. In this position, the pins of the electrical component 40 are vertically downward. The two rows of pins facing vertically downward are projected onto the mirror surfaces of the left and right mirrors 240, respectively. The camera 30 captures the image of the pins in the mirrors 240 and transmits it to the external recognition terminal for identification.

[0015] See also Figure 2 The mirror 240 is gradually tilted from bottom to top toward the side away from the hollow area 230. The tilted lens 240 can well enable the image in the mirror 240 to be captured by the camera 30.
