Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to an integrated circuit testing device adapted to different integrated circuit boards. Background Art

[0002] Integrated circuit boards, or PCBs for short, are the basic carriers used to support and connect electronic components. They are widely used in various electronic devices, such as computers, mobile phones, and automotive electronic systems, and are a vital component of modern electronic information technology. After production, integrated circuit boards require testing of the integrated circuits.

[0003] Existing integrated circuit board inspection equipment lacks a flexible and efficient solution for clamping circuit boards of varying sizes. Many existing inspection systems are designed primarily for circuit boards of specific sizes. Dimensionally varying circuit boards often require auxiliary tools or manual adjustments, which not only reduces inspection efficiency but also increases operational complexity. Existing inspection equipment typically utilizes fixed or mechanically locked clamping methods, which present significant limitations and deficiencies when adapting to circuit boards of varying sizes. Fixed clamping methods can result in insecure fixation for smaller circuit boards, while mechanically locked clamping methods can overtighten and cause unnecessary stress or even damage to larger circuit boards.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The weight of different integrated circuit boards varies, causing the conductive pillar to move downward to different degrees. This also causes the current flowing into electromagnet 2 to vary, resulting in different repulsive forces exerted by electromagnet 2 on fixed magnetic block 3, which in turn causes the movable clamp to move different distances. This allows for stable and effective clamping of integrated circuit boards of different sizes. This design greatly enhances the flexibility and applicability of the equipment, allowing operators to easily handle integrated circuit boards of various sizes without having to replace fixtures or perform tedious manual adjustments, thereby greatly simplifying the workflow and improving work efficiency.

[0017] 2. The weights of different integrated circuit boards vary, causing the conductive pillar to move downward to different degrees. This, in turn, causes the current flowing into electromagnet 1 to vary, thereby changing the repulsive force exerted by electromagnet 1 on fixed magnetic block 4. This causes the adjustment block to carry the detection head to rise to different heights, allowing comprehensive and accurate detection of integrated circuit boards of different sizes. This function greatly improves the use effect and practicality of the entire detection device, not only avoiding detection errors or failures caused by size mismatch, but also significantly improving the efficiency and accuracy of detection work, meeting diverse detection needs, and further enhancing its market competitiveness and practical value.

[0018] 3. When the moving frame approaches the stop block, the electromagnet 1 can exert a repulsive force on the moving magnetic plate, so that the moving magnetic plate moves inside the stop block, thereby pushing the airbag pressure plate 1 to move through the connecting rod, squeezing the plastic airbag 1, so that the gas inside the plastic airbag 1 enters the interior of the exhaust frame 1, and then is ejected through the exhaust frame 1 to perform jet cleaning on the detection end of the integrated circuit board, which can effectively remove any tiny particles, dust, grease or other debris attached to the surface of the detection end, ensuring that the detection end is clean and free of debris, ensuring the accuracy of the integrated circuit detection of the integrated circuit board, not only improving work efficiency, but also reducing the risk of human error, making the entire detection process smoother and more controllable;

[0019] 4. When the integrated circuit board is placed on top of the placement plate, the conductive column moves downward, driving the airbag pressure plate 2 to move downward, squeezing the plastic airbag 2, so that the gas inside the plastic airbag 2 enters the exhaust frame 2, and then is discharged through the exhaust frame 2. The gas passes through the wet sponge and enters the air, humidifying the detection environment, making it easier for the charge to be conducted and dissipated through water molecules, reducing the risk of electrostatic discharge. This not only protects the integrated circuit board from electrostatic damage, but also ensures the stability and accuracy of signal transmission during the detection process.

[0033] The working principle of the above technical solution is as follows: first, the integrated circuit board to be tested is placed on top of the two placement plates 9, and the position to be tested is aligned with the position of the detection port 6. Under the action of the integrated circuit board's own gravity, the conductive column 26 can be pressed downward to move downward, so that the relative position of the conductive column 26 and the movable power ring 27 changes. Then, the switch button 3 is pressed to make the battery 16 supply power to the electromagnet 2 32 and the electromagnet 1 31. When the electromagnet 2 32 receives power, it generates magnetism, thereby applying a repulsive force to the fixed magnetic block 3 44 through the electromagnet 2 32, so that the movable clamping plate 13 moves on the top of the detection table 1, thereby clamping the integrated circuit board to be tested placed on the top of the placement plate 9 between the rubber pad 15 and the mounting box 4. Furthermore, the weights of different integrated circuit boards are different, which results in different degrees of downward movement of the conductive pillar 26, and different lengths of the conductive pillar 26 between the movable connecting ring 27 and the fixed connecting ring 28, resulting in different amounts of connected resistance. Therefore, the currents flowing into the second electromagnet 32 ​​are different, which results in different repulsive forces exerted by the second electromagnet 32 ​​on the fixed magnetic block 3 44, and thus different distances of movement of the movable clamp 13, thereby achieving stable and effective clamping and fixing of integrated circuit boards of different sizes. This design greatly improves the flexibility and applicability of the equipment, allowing operators to easily handle integrated circuit boards of various sizes without having to replace fixtures or perform tedious manual adjustments, thereby greatly simplifying the workflow and improving work efficiency. More importantly, the stable clamping and fixation lays a solid foundation for the subsequent precise detection work, ensuring that the integrated circuit board will not affect the accuracy of the detection result due to shaking or displacement during the detection process, thereby facilitating efficient and accurate detection of integrated circuit boards of different sizes. In addition, when the battery 16 supplies power to the electromagnet 1 31, the fixed magnetic block 17 can apply a repulsive force to the electromagnet 1 31, so that the electromagnet 1 31 drives the movable frame 18 to move inside the installation box 4, so that the movable frame 18 contacts one side of the block 19, and the position of the fixed magnetic block 5 41 corresponds to the position of the fixed magnetic block 2 43. The fixed magnetic block 2 43 will apply a repulsive force to the fixed magnetic block 5 41, so that the detection head 39 moves on the top of the adjustment block 38. The detection head 39 moves so that the detection head of the detection head 39 is fitted with the detection end of the integrated circuit board to be detected, thereby realizing the detection of the integrated circuit of the integrated circuit board. In addition, the weight of different integrated circuit boards is different, so that the degree of downward movement of the conductive column 26 is different, and the length of the conductive column 26 between the movable electric ring 27 and the fixed electric ring 28 is different, so that the amount of connected resistance is different, so the current passed through the electromagnet 1 31 is different, so that the magnetic force of the electromagnet 1 31 is different, so that the repulsive force exerted by the electromagnet 1 31 on the fixed magnetic block 40 changes, so that the adjustment block 38 carries the detection head 39 to different heights. The larger the integrated circuit board, the greater the gravity, the smaller the current connected to the electromagnet 1 31, and the smaller the magnetic force of the electromagnet 1 31.This allows the adjustment block 38 to rise slightly. Smaller integrated circuit boards have less gravity, while the current connected to electromagnet 1 31 is large, resulting in a stronger magnetic force. This allows the adjustment block 38 to rise significantly, enabling comprehensive and accurate testing of integrated circuit boards of varying sizes. This function greatly enhances the effectiveness and practicality of the entire testing device, not only avoiding testing errors or failures caused by size mismatches but also significantly improving testing efficiency and accuracy, meeting diverse testing needs and further enhancing its market competitiveness and practical value.

[0035] When the movable frame 18 approaches the stop block 19, the electromagnet 31 can apply a repulsive force to the movable magnetic plate 20, so that the movable magnetic plate 20 moves inside the stop block 19, thereby pushing the airbag pressure plate 22 to move through the connecting rod 24, squeezing the plastic airbag 23, so that the gas inside the plastic airbag 23 enters the exhaust frame 8, and then is ejected through the exhaust frame 8 to perform jet cleaning on the detection end of the integrated circuit board, which can effectively remove any tiny particles, dust, grease or other debris attached to the surface of the detection end, ensure that the detection end is clean and free of debris, and ensure the accuracy of the detection of the integrated circuit of the integrated circuit board, which not only improves work efficiency, but also reduces the risk of human error, making the entire detection process smoother and more controllable.

[0036] In another embodiment, Figures 1-8 As shown, two plastic airbags 2 46 are symmetrically installed inside the test platform 1, and airbag pressure plates 29 are fixedly installed at the bottom of the conductive column 26. The airbag pressure plates 29 are respectively located directly above the two plastic airbags 2 46.

Wet sponges 11 are installed on both sides of the test platform 1, and the wet sponges 11 are respectively located at the air outlets of the exhaust frame 2 45.

[0037] When the integrated circuit board is placed on top of the placement plate 9, the conductive column 26 moves downward, driving the airbag pressure plate 29 to move downward, squeezing the plastic airbag 2 46, so that the gas inside the plastic airbag 2 46 enters the exhaust frame 2 45, and then is discharged through the exhaust frame 2 45. The gas enters the air through the wet sponge 11, humidifying the detection environment, making it easier for the charge to be conducted and dissipated through water molecules, reducing the risk of electrostatic discharge, which not only protects the integrated circuit board from electrostatic damage, but also ensures the stability and accuracy of signal transmission during the detection process.

[0038] Working principle: First, place the integrated circuit board to be tested on top of the two placement plates 9, and make the position to be tested correspond to the position of the detection port 6. Under the action of the integrated circuit board's own gravity, the conductive column 26 can be pressed downward to move downward, so that the relative position of the conductive column 26 and the movable connecting ring 27 changes. When the integrated circuit board is placed on top of the placement plate 9, the conductive column 26 moves downward to drive the airbag pressing plate 29 to move downward, squeezing the plastic airbag 2 46, so that the gas inside the plastic airbag 2 46 enters the interior of the exhaust frame 2 45, and then is discharged through the exhaust frame 2 45, and the gas enters the air through the wet sponge 11, humidifying the detection environment, making it easier for the charge to be conducted and dissipated through the water molecules, reducing The risk of electrostatic discharge, which not only protects the integrated circuit board from electrostatic damage, but also ensures the stability and accuracy of signal transmission during the detection process, and then presses the switch button 3, so that the battery 16 supplies power to the electromagnet 2 32 and the electromagnet 1 31, wherein the electromagnet 2 32 generates magnetism when receiving electricity, thereby applying a repulsive force to the fixed magnetic block 3 44 through the electromagnet 2 32, so that the movable clamping plate 13 moves on the top of the detection table 1, thereby clamping the integrated circuit board to be detected placed on the top of the placement plate 9 between the rubber pad 15 and the mounting box 4, and the weight of different integrated circuit boards is different, so that the degree of downward movement of the conductive column 26 is different, and the length of the conductive column 26 between the movable electric ring 27 and the fixed electric ring 28 is different, from The amount of resistance connected is different, so the current passed through the electromagnet 2 32 is different, which makes the repulsive force exerted by the electromagnet 2 32 on the fixed magnetic block 3 44 different, so that the moving clamp 13 moves a different distance, thereby achieving stable and effective clamping and fixing of integrated circuit boards of different sizes. This design greatly improves the flexibility and applicability of the equipment, allowing operators to easily handle integrated circuit boards of various sizes without having to replace fixtures or perform tedious manual adjustments, thereby greatly simplifying the workflow and improving work efficiency. More importantly, the stable clamping and fixation lays a solid foundation for subsequent precise detection work, ensuring that the integrated circuit board will not be affected by shaking or displacement during the detection process, affecting the accuracy of the detection results. , thereby facilitating efficient and accurate detection of integrated circuit boards of different sizes. In addition, when the battery 16 supplies power to the electromagnet 1 31, the fixed magnetic block 17 can apply a repulsive force to the electromagnet 1 31, so that the electromagnet 1 31 drives the movable frame 18 to move inside the installation box 4, so that the movable frame 18 contacts one side of the block 19, and the position of the fixed magnetic block 5 41 corresponds to the position of the fixed magnetic block 2 43. The fixed magnetic block 2 43 will apply a repulsive force to the fixed magnetic block 5 41, so that the detection head 39 moves on the top of the adjustment block 38, so that the detection head of the detection head 39 is in contact with the detection end of the integrated circuit board to be detected, thereby realizing the detection of the integrated circuit of the integrated circuit board. In addition, the weight of different integrated circuit boards is different.As a result, the degree of downward movement of the conductive column 26 is different, and the length of the conductive column 26 between the movable electric ring 27 and the fixed electric ring 28 is different, so that the amount of connected resistance is different, so the current passed through the electromagnet 31 is different, so that the magnetic force of the electromagnet 31 is different, so that the repulsive force exerted by the electromagnet 31 on the fixed magnetic block 40 is changed, so that the adjustment block 38 carrying the detection head 39 rises to different heights. The larger integrated circuit board has a greater gravity, the current connected to the electromagnet 31 is smaller, and the magnetic force of the electromagnet 31 is smaller, so that the adjustment block 38 rises less. The smaller integrated circuit board has a smaller gravity, the current connected to the electromagnet 31 is larger, and the magnetic force of the electromagnet 31 is larger, so that the adjustment block 38 rises more. Comprehensive and accurate detection of integrated circuit boards of different sizes can be carried out. This function greatly improves the use effect and practicality of the entire detection device, not only avoiding the problem of size mismatch. The invention can not only avoid detection errors or failures caused by the above, but also significantly improve the efficiency and accuracy of the detection work, meet the diverse detection needs, and further enhance its market competitiveness and practical value. When the moving frame 18 approaches the block 19, the electromagnet 31 can apply a repulsive force to the moving magnetic plate 20, so that the moving magnetic plate 20 moves inside the block 19, thereby pushing the airbag pressure plate 22 to move through the connecting rod 24, squeezing the plastic airbag 23, so that the gas inside the plastic airbag 23 enters the interior of the exhaust frame 8, and then is ejected through the exhaust frame 8 to perform jet cleaning on the detection end of the integrated circuit board, which can effectively remove any tiny particles, dust, grease or other debris attached to the surface of the detection end, ensure that the detection end is clean and free of debris, and ensure the accuracy of the detection of the integrated circuit board integrated circuit, which not only improves work efficiency, but also reduces the risk of human error, making the entire detection process smoother and more controllable.
