Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, specifically to a device for testing the pins of electronic components on a circuit board. Background Technology

[0002] During circuit board manufacturing, multiple electronic components need to be soldered onto the circuit board. After soldering, testing equipment is needed to inspect the pins of the electronic components to determine whether there are any bent or poorly soldered pins. Some circuit boards are double-sided when soldering electronic components. Since there are electronic components on both sides of the circuit board, double-sided testing is required when testing the pins. The current testing equipment does not have the function of flipping the circuit board. When performing double-sided testing, the circuit board needs to be manually removed, flipped, and put back on the device, which increases the testing time. Therefore, it needs to be improved. Therefore, it is necessary to invent a device for detecting the pins of electronic components on a circuit board. Utility Model Content

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Example 1: like Figures 1-8 As shown, the electronic device pin detection device on the circuit board includes a substrate 1. Two support plates 2 are fixedly connected to the top of the substrate 1. A knob 3 is embedded on each of the two support plates 2 and the knob 3 is connected to the support plate 2 through a bearing. A rotating rod 4 is fixedly connected to the opposite side of the two knobs 3. A connecting rod 5 is fixedly connected to the front end and the rear end of the two rotating rods 4. Both rotating rods 4 are equipped with fixing components, which are used to clamp the circuit board. One of the knobs 3 is equipped with an auxiliary component to prevent the two knobs 3, the two rotating rods 4, and the circuit board from rotating arbitrarily; In this implementation scheme, the circuit board can be fixed by two fixing components. When the circuit board needs to be flipped, the auxiliary control component works. Then, the two knobs 3 can be turned to rotate the two rotating rods 4, the two connecting rods 5 and the circuit board, so that the circuit board can be flipped. In this way, during double-sided inspection, it is not necessary to manually remove the circuit board, flip it and put it back on the device, which can reduce the inspection time. In this embodiment, the fixing component includes two locking blocks 6, each of which has a locking groove. One locking block 6 is fixedly connected to the rotating rod 4, and the other locking block 6 is in sliding contact with the rotating rod 4. The rotating rod 4 has a through groove, in which a moving block 7 is slidably disposed. The moving block 7 is fixedly connected to the other locking block 6. A sliding rod 8 is fixedly connected in the through groove. The sliding rod 8 passes through the moving block 7 and is in sliding contact with it. A spring 9 is sleeved on the outside of the sliding rod 8, and both ends of the spring 9 are fixedly connected to the moving block 7 and the rear side of the through groove, respectively. It should be noted that when securing the circuit board, hold it and insert it at an angle into the slots on the two rear locking blocks 6. Pushing it backward will move the two rear locking blocks 6 and the two moving blocks 7 backward, simultaneously compressing the two springs 9. As the distance between the two rear locking blocks 6 and the two front locking blocks 6 increases, the front of the circuit board aligns with the slots on the two front locking blocks 6. Then, the springs 9 will return, reducing the distance between the front and rear locking blocks 6, thus clamping and securing the circuit board. Figure 8 As shown; In this embodiment, the auxiliary component includes a groove and two insertion holes. The groove and two insertion holes are both opened on one of the knobs 3, and the two insertion holes are respectively located on the front and rear sides of the groove. A housing 10 is fixedly sleeved on one of the support plates 2. A through hole is opened on one side of the housing 10. One of the knobs 3 passes through the through hole. Slots are opened on both the front and rear sides of the housing 10. A push plate 11 is slidably arranged in the groove. A first insertion rod 12 is fixedly connected to the rear side of the push plate 11. The first insertion rod 12 passes through one of the insertion holes and the slot and slides in contact with them. A second insertion rod 13 is fixedly connected to the front side of the push plate 11. The front end of the second insertion rod 13 is slidably inserted into another insertion hole. A second spring 14 is sleeved on the outside of the second insertion rod 13, and the two ends of the second spring 14 are fixedly connected to the push plate 11 and the front side of the groove, respectively. It should be noted that when turning the two knobs 3 to flip the circuit board, the auxiliary component should be controlled first to release the restriction on the left knob 3. When the restriction is released, the push plate 11 is pulled forward, which allows the second insertion rod 13 and the first insertion rod 12 to move forward. This allows the first insertion rod 12 to move out of the slot on the rear side, and at the same time, the second spring 14 is compressed. Then, the two knobs 3 can be turned to make the circuit board rotate half a turn, thus achieving the flipping. After the flipping is made, the push plate 11 is released, and the push plate 11, the first insertion rod 12, and the second insertion rod 13 can be reset under the action of the spring 14. Then, the first insertion rod 12 can be inserted into the slot on the front side. This restricts the left knob 3 again, which can prevent the circuit board from rotating randomly. In this embodiment, a gooseneck rod 15 is fixedly connected to the top of the substrate 1, and a magnifying glass 16 is fixedly connected to the end of the gooseneck rod 15. It should be noted that when inspecting the pins of electronic components on a circuit board, you can use a magnifying glass to visually inspect the pins for bending or poor soldering. In addition, the magnifying glass 16 is connected by a gooseneck rod 15. When in use, the gooseneck rod 15 can be bent at will, so that the magnifying glass 16 can be stopped in any position. The gooseneck rod 15 is supported by galvanized iron wire or steel wire. When in use, it can be bent at will by external force, and it can also maintain a fixed angle by relying on the toughness of the metal.

[0017] Example 2: like Figure 9 As shown, unlike Embodiment 1, a bracket 17 is fixedly connected to the top of the substrate 1, and a high-definition camera 18 is fixedly embedded on the bracket 17. In this embodiment, a high-definition camera 18 is designed and is located above the circuit board. When performing testing, the high-definition camera 18 can take pictures of the circuit board and then check whether there are bent or poorly soldered pins through the pictures. In actual use, the high-definition camera 18 can be wirelessly connected to the computer via Bluetooth, so that the pictures can be directly transmitted to the computer and then conveniently viewed. The wireless Bluetooth connection between the high-definition camera 18 and the computer is common knowledge and will not be described here. The model and specifications of the high-definition camera 18 in this utility model need to be selected and determined according to the actual specifications of the entire device. Moreover, the above-mentioned components are very mature products in the prior art, so the specific model and specifications will not be described in detail. Furthermore, the control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
