Description

Technical Field

[0001] This utility model relates to the field of FPC assembly technology, and in particular to an FPC assembly nut assembly status detection tool. Background Technology

[0002] FPC is an abbreviation for Flexible Printed Circuit Board, a type of printed circuit board made of flexible substrate. It is characterized by its thinness, flexibility, and high temperature resistance, and is widely used in electronic devices where dynamic connections are required or space is limited, such as mobile phones, laptops, and camera modules. FPC itself is highly flexible and needs to be fixed with other rigid components by nuts to ensure that the circuit board maintains a stable connection under vibration or mechanical stress. If the nuts are installed backwards or are missing, or if the nuts are reversed, the threads may not be able to engage with the mating parts, thus causing a circuit break.

[0003] In traditional techniques, the inspection of nuts in FPC assembly mainly relies on visual inspection by operators holding the product. Operators hold the product in their hands and observe whether the nuts are installed backwards. Since the nuts used in FPC assembly are small, their positions are easily obscured by their hands when handling them. Furthermore, the small size of the nuts requires frequent and careful observation, making visual inspection susceptible to fatigue and resulting in a high rate of missed inspections. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an assembly status detection tool for FPC assembly nuts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an FPC assembly nut assembly status detection tool, including a mounting frame, two limiting rods fixedly connected to the upper surface of the mounting frame, an electric cylinder fixedly mounted on one side of the mounting frame, and a detection component provided at the output end of the electric cylinder; The detection assembly includes a top plate, which is fixedly connected to the output end of the electric cylinder. Multiple spacing columns are fixedly connected to the lower surface of the top plate, and a base plate is fixedly connected to one end of each spacing column. Two connecting sleeves are fixedly connected to both sides of the upper surface of the base plate. A groove is provided on one side of the base plate, and two square rods are fixedly connected inside the groove. Two double-hole sleeves are slidably connected to the outside of the two square rods, and an adjusting block is fixedly connected to one side of each double-hole sleeve.

[0006] As a further description of the above technical solution: The connecting sleeve is slidably connected to the outside of the limiting rod. The adjusting block has an adjusting groove inside. Two fixing brackets are slidably connected inside the adjusting groove. Probes are fixedly installed inside the fixing brackets.

[0007] As a further description of the above technical solution: An internal threaded sleeve is fixedly connected to one side of the fixing frame, and an observation plate is fixedly connected to one side of the internal threaded sleeve. A bidirectional lead screw is rotatably connected to the upper surface of the adjusting block, and a knob is fixedly connected to one end of the bidirectional lead screw.

[0008] As a further description of the above technical solution: A short ruler is fixedly connected to the upper surface of the adjusting block, and the short ruler is set on one side of the bidirectional lead screw. A pointer is fixedly connected to the upper surface of the double-hole sleeve, and a long ruler is fixedly connected to the upper surface of the base plate.

[0009] As a further description of the above technical solution: A sliding sleeve is fixedly connected to one side of the adjusting block, and a locking bolt is threadedly connected to one side of the sliding sleeve. A connecting frame is fixedly connected to one side of the base plate, and the two sliding sleeves are slidably connected to the outside of the connecting frame.

[0010] As a further description of the above technical solution: The upper surface of the adjusting block is provided with a pressing component, which includes a long block that is fixedly connected to the upper surface of the adjusting block. A plurality of recesses are provided on one side of the long block.

[0011] As a further description of the above technical solution: A spring is fixedly connected inside the concave hole, and a push post is fixedly connected to one end of the spring. A pressure plate is fixedly connected to one end of each of the push posts.

[0012] This utility model has the following beneficial effects: 1. This utility model, through the setting of the detection component, uses multiple probes to detect the edges of the nuts on both sides of the circuit board after the nuts are installed. If the nuts are installed backwards, the probes cannot contact the effective position of the nuts, thus causing the circuit to break, thereby determining that the nuts are installed backwards. This helps to automatically detect the assembly status of the nuts, thereby improving detection efficiency. In addition, the two adjusting blocks slide outside the square rod, which helps to adjust the distance between the two sets of probes on both sides, while the fixed bracket that slides inside the adjusting groove helps to adjust the distance between the two probes in the same group. This helps to detect the assembly status of adjacent nuts in different batches and different positions, improving the versatility of the detection component.

[0013] 2. By setting up the clamping component, the spring force output by the spring is transmitted to the pressure plate through the push column, which helps the pressure plate to generate a squeezing force on the fixed frame. After the fixed frame is adjusted in position by the double-acting screw through the internal thread sleeve, when the fixed frame is fixed in position by the double-acting screw in the self-locking state, a lateral force is generated on the fixed frame, thereby further improving the stability of the fixed frame position and reducing the possibility of displacement.

[0026] Working principle: In use, first install the clamp for fixing the circuit board on the bottom upper surface of the mounting bracket 1, and then fix the circuit board with the mounting nut on the bottom upper surface of the mounting bracket 1, under multiple probes 14. When adjusting the position of the probes 14 according to the installation position of the nuts on the circuit board of the current batch: First, measure the distance between the two nuts to be tested, and then adjust the lateral position between the two sets of probes 14: Loosen the locking bolt 23, slide the sliding sleeve 22 outside the connecting frame 24. When the sliding sleeve 22 moves, it will drive the adjusting block 11 to move, which in turn will drive the double hole sleeve 10 to move. When the double hole sleeve 10 moves, the pointer 20 will slide on the surface of the ruler 21. Then, according to the value pointed to by the pointer 20 on the ruler 21, adjust the distance between the two sliding sleeves 22 until the value is the same as the distance between the two nuts on the circuit board. Then tighten the locking bolt 23 so that one end of it is pressed against the connecting frame 24, and fix the position of the sliding sleeve 22, thereby completing the lateral position adjustment of the two sets of probes 14. Next, adjust the longitudinal position of the probes 14 in the same group according to the surface diameter of the nut: First, measure the diameter of the nut surface. Then, rotate the knob 18 to drive the double-acting screw 17 to rotate. When the double-acting screw 17 rotates, because its external threads are in opposite directions, and under the connection of the internal thread sleeve 15, it drives the two fixed brackets 13 to slide inside the adjustment groove 12 and generate relative movement. It will also slide on one side of the pressure plate 29, causing the probe 14 to be moved by the fixed bracket 13. When the internal thread sleeve 15 moves, it will drive the observation piece 16 to move on the surface of the short ruler 19, thereby observing the distance between the two observation pieces 16 on the short ruler 19 and judging whether the movement position of the two probes 14 in the same group is appropriate, thus completing the longitudinal spacing adjustment of the probes 14 in the same group. After adjustment, stop rotating knob 18. When the fixed bracket 13 stops moving, pressure plate 29 will push push column 28 due to spring 27. Push column 28 will transmit elastic force to pressure plate 29, causing pressure plate 29 to press one side of the two fixed brackets 13. This makes it easier to fix the position of fixed bracket 13 under the self-locking of double-acting screw 17, so that the two probes 14 in the same group are on both sides of the nut. Then, start electric cylinder 3 so that its output end drives top plate 4 to move bottom plate 6 down under the connection of spacing column 5. Bottom plate 6 drives probe 14 down. Probe 14 is used to detect the position of nut. The position of probe 14 is aligned with the edge of nut. When nut is installed backward, probe 14 cannot contact the effective position, causing the circuit to break.
