DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0030] Embodiment 1

[0031] like Figures 1 to 10As shown, a detection and production device for the pin processing of electronic components includes a detection component and a cutting angle component. The detection component includes a detection tube 1, a pin bending detection plate 2, a pin length detection plate 3, a first distance measuring sensor 6 and a second distance measuring sensor 7. The top of the detection tube 1 is provided with a detection cavity 4 along its own axial direction. The pin bending detection plate 2 is fixed in the detection cavity 4. A plurality of detection holes 5 are formed through the pin bending detection plate 2. The plurality of detection holes 5 correspond to the pins of the electronic components one by one. The offset diameter of the bottom of the pin of the qualified electronic component is equal to the diameter of the detection hole 5. The pin length detection plate 3 is located directly below the pin bending detection plate 2. The pin length detection plate 3 has the freedom to move along the axial direction of the detection tube 1. The pin length detection plate 3 corresponding to the detection hole 5 A through hole 8 is opened through the position, and each through hole 8 is correspondingly provided with a sealing plate 9, which is slidably connected to the pin length detection plate 3, and the sealing plate 9 is used to block the through hole 8. A center hole 10 is opened through the middle of the pin bending detection plate 2 and the middle of the pin length detection plate 3. The first distance sensor 6 and the second distance sensor 7 are both installed below the pin length detection plate 3. The detection path of the first distance sensor 6 passes through the center hole 10. The second distance sensor 6 is used to detect the height of the pin length detection plate 3. Before the electronic components are cut, quality inspection is carried out first. Only the electronic components that meet the quality requirements are cut and put into production. The electronic components to be inspected are loaded into the detection tube 1, and the pin shape of the electronic components is first inspected by the pin bending detection plate 2. state, judge whether the bending angle of the pin meets the requirements, and detect the bending degree of the pin through the detection hole 5. Since the diameter of the detection hole 5 is equal to the offset diameter of the bottom of the pin of the electronic component, that is, within the bending range of the pin with qualified quality, the pin with the largest bending can pass through the detection hole 5, while the pin exceeding the bending range cannot pass through the detection hole 5. When each pin of the electronic component meets the bending requirements, the pin of the electronic component can smoothly pass through the corresponding detection hole 5, so that the electronic component contacts the pin bending detection plate 2, and the height of the electronic component is detected by the first distance measuring sensor 6. Therefore, whether the quality of the pin is qualified is judged by the height of the electronic component in the detection tube 1. The electronic component that is bent beyond the range has a higher height in the detection tube 1, and the unqualified The electronic components are directly unloaded from the detection tube 1 without the next length detection. The electronic components whose pin bending meets the requirements continue to be tested for length. The length of the pin is detected by the pin length detection board 3 to determine whether the pin length of the electronic component meets the welding requirements. The specific detection process is to first block one of the through holes 8 through the sealing plate 9, and the pin that can pass through the detection hole 5 can also pass through the through hole 8. After blocking one of the through holes 8, the pin length detection board 3 moves upward close to the pin bending detection board 2, and the pin corresponding to the blocked through hole 8 will contact the sealing plate 9, while the remaining pins are not restricted and can pass through the through hole 8 normally. The sealing plate 9 acts on the pin, and the electronic component is supported by the pin. As the pin length detection board 3 moves, the electronic component will be lifted up.After the first distance measuring sensor 6 detects that the electronic component has moved, the surface pin has contacted the sealing plate 9. The height of the electronic component at this time is detected by the first distance measuring sensor 6, and the height of the pin length detection plate 3 is detected by the second distance measuring sensor 7. The distance between the bottom surface of the second detection sensor 7 and the sealing plate 9 is a fixed value. The length of the pin can be obtained by subtracting the fixed value and the detection value of the second distance measuring sensor 7 from the detection value of the first distance measuring sensor 6, thereby completing the length detection of a pin. Then, the pin length detection plate 3 moves downward to disengage the pin from the through hole 8, and then the next through hole 8 is blocked, and the length of the next pin is detected again in the above manner. In this way, the length detection of each pin of the electronic component is completed. When the length of a certain pin does not meet the requirements, the detection process is interrupted, and the electronic component is cut to the next component for detection. When the detection of each pin is completed and the quality meets the requirements, the electronic component is put into the corner cutting operation, and the length of each pin is cut to the required length to facilitate subsequent welding operations.
