Technical Field

[0001] The utility model relates to the technical field of circuit inspection, in particular to a size-adjusting jig for circuit inspection. Background Art

[0002] Circuit inspection is an important step to ensure the normal function and reliable performance of electronic devices and systems, which usually includes detecting the soldering quality, connection status and electrical performance on the circuit board. During the circuit inspection process, the use of a size-adjusting jig is crucial because it can accurately position and fix circuit boards and components of various specifications, ensuring the correct docking and stable contact between the inspection tool and the object to be measured. The use of the size-adjusting jig not only improves the accuracy and efficiency of the inspection, but also reduces the risk of operation errors and equipment damage, thus enhancing the overall inspection quality and production efficiency.

[0003] The working principle of traditional circuit inspection is to detect the soldering points, connection status and electrical performance on the circuit board by using various test tools and equipment. First, place the circuit board on the size-adjusting jig and fix it with positioning pins or jigs to ensure the stability of the circuit board. Then, use inspection probes or test instruments to contact the test points on the circuit board, and detect various parameters of the circuit board by applying voltage, current or signals. The test instrument will capture and analyze the feedback signal to judge the soldering quality, connection status of the circuit board and whether there are short circuits, open circuits or other faults. The whole process relies on the accurate positioning and stable support of the jig to ensure good contact between the detection tool and the test point, thus improving the accuracy and efficiency of the detection.

[0004] In traditional circuit inspection, the circuit board is fixed by using mechanical jigs and positioning pins. Such a setting makes it difficult to accurately adjust the product, and it is easy to generate tiny positioning errors, resulting in inaccurate docking between the test point and the detection probe, which affects the accuracy of the detection result.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 4 Figure 4 , an embodiment provided by the present utility model: a size-adjustable jig for circuit inspection, including a carrier main body 1. A fixed seat 16 is slidably connected to the upper surface of the carrier main body 1. An adjustment platform 3 is fixedly connected to the upper surface of the fixed seat 16. A bracket 11 is fixedly connected to the upper surface of the carrier main body 1. An ART fixed platform 4 is fixedly connected to the outer wall of the bracket 11. A product 12 is arranged on the outer wall of the ART fixed platform 4. An electrical measurement platform 2 is arranged above the carrier main body 1. A measuring micrometer 5 is fixedly connected to the outer wall of the carrier main body 1. An adjustment component is arranged inside the carrier main body 1. The adjustment component is used for adjusting the positions of the ART fixed platform 4 and the electrical measurement platform 2. The adjustment component includes a first adjustment screw 6. The outer wall of the first adjustment screw 6 is rotatably connected inside the carrier main body 1. The outer wall of the first adjustment screw 6 is threadedly connected inside the fixed seat 16. A second adjustment screw 7 is threadedly connected inside the carrier main body 1. The outer wall of the second adjustment screw 7 is rotatably connected inside the electrical measurement platform 2. A telescopic guide rod 10 is fixedly connected to the outer wall of the fixed seat 16. The outer wall of the telescopic guide rod 10 is fixedly connected to the outer wall of the bracket 11. Sliders 8 are fixedly connected to both sides of the outer wall of the electrical measurement platform 2. A slide rail 9 is slidably connected inside the slider 8. The outer wall of the slide rail 9 is fixedly connected to a support plate 15. The lower surface of the support plate 15 is fixedly connected to the upper surface of the carrier main body 1. A limit groove 17 is formed inside the adjustment platform 3. The adjustment platform 3 is arranged below the product 12. The adjustment platform 3 is arranged above the carrier main body 1, and the product 12 is arranged above the fixed seat 16;

[0025] Specifically, first place the product 12 to be debugged in the preset limit groove 17 inside the adjustment platform 3, then place the product 12 on the outer wall of the ART fixed platform 4 so that the product 12 covers above the product 12. Then drive the first adjustment screw 6 to rotate inside the carrier main body 1. Due to the threaded relationship between the first adjustment screw 6 and the fixed seat 16, the fixed seat 16 slides on the upper surface of the carrier main body 1 as the first adjustment screw 6 rotates, thereby driving the adjustment platform 3 and the product 12 above the adjustment platform 3 to be debugged in the Y direction. The debugging accuracy can reach ±0.001 mm. During this process, the movement of the fixed seat 16 is guided by the telescopic guide rod 10 to make the movement of the product 12 more stable. Then drive the second adjustment screw 7 to rotate inside the electrical measurement platform 2. Due to the threaded relationship between the second adjustment screw 7 and the carrier main body 1, the electrical measurement platform 2 moves up and down as the second adjustment screw 7 rotates. During this process, the movement of the electrical measurement platform 2 will drive the slider 8 to slide on the outer wall of the slide rail 9, thereby making the movement of the electrical measurement platform 2 more stable.

[0026] Reference Figure 1 - Figure 3, one end of the product 12 is fixedly connected to the first test end 13, and the other end of the product 12 is fixedly connected to the second test end 14;

[0027] Specifically, when the electrical test platform 2 rises to be able to contact the probe of the product 12, a multimeter or a buzzer can be used to conduct a conduction test on the first test end 13 and the second test end 14 of the product 12.

[0028] Working principle: When the size-adjusting fixture for circuit inspection is needed, first place the product 12 in the limiting groove 17 and place it on the provided ART fixed platform 4 to ensure that the product 12 is stably placed on the fixture. Subsequently, start the first adjusting screw 6, so that the fixed seat 16 slides on the upper surface of the carrying body 1 as the first adjusting screw 6 rotates, thereby driving the adjusting platform 3 and the product 12 on the platform to conduct Y-direction debugging. The accuracy of this debugging process can reach ±0.001 mm. During the adjustment process, the telescopic guide rod 10 guides the movement of the fixed seat 16, increasing the stability of the movement and avoiding the shaking of the product 12 during the debugging process. Then, start the second adjusting screw 7, and make it rotate inside the electrical test platform 2. The threaded relationship between the second adjusting screw 7 and the carrying body 1 causes the electrical test platform 2 to move up and down as the second adjusting screw 7 rotates. While the electrical test platform 2 is moving, the slider 8 slides on the outer wall of the slide rail 9, further ensuring the movement stability of the electrical test platform 2. When the electrical test platform 2 rises to be able to contact the first test end 13 and the second test end 14 of the product 12, a multimeter or a buzzer can be used to conduct a conduction test on the product 12 to check the connectivity of the circuit.
