Description

Technical Field

[0001] This invention relates to the field of testing technology, specifically to an adjustable single-beam PCB rapid diagnostic instrument. Background Technology

[0002] In recent years, with the continuous development of the electronics market, PCBs have been used more and more widely, and the requirements for PCB production inspection have become increasingly stringent. Currently, PCB inspection can be broadly divided into two categories: electrical testing and visual testing. Existing single-light PCB rapid diagnostic instruments, equipped with a visible light camera and a thermal imaging module, utilize dual-light fusion display technology to clearly show the outline of the motherboard, enabling precise location of overheating faults in one second and accurate detection of leakage problems as low as 7 milliamps. Simultaneously, the backend software supports regional temperature measurement, high and low temperature tracking, and intelligent sample comparison functions, significantly reducing the false alarm rate of fault points and greatly shortening repair waiting time.

[0003] However, current PCB inspection equipment on the market is generally large and heavy, resulting in poor mobility and inflexible observation. Furthermore, most existing equipment lacks good folding and storage capabilities, occupying a large space and making it inconvenient to carry and store. In addition, existing equipment often lacks a stable mechanical locking structure when adjusting height, leading to insufficient support rigidity after adjustment, making it prone to wobbling and affecting inspection accuracy. Moreover, the inspection head is usually fixed, making disassembly and maintenance cumbersome and failing to meet the needs of rapid on-site inspection and efficient operation.

[0004] Therefore, those skilled in the art have provided an adjustable single-beam PCB rapid diagnostic instrument to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable single-beam PCB rapid diagnostic instrument, which solves the problems of existing testing equipment being bulky and inconvenient to move, lacking folding and storage functions, prone to shaking after height adjustment affecting accuracy, and cumbersome disassembly and maintenance of the testing head.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable single-light PCB rapid diagnostic instrument includes a base, a liftable lower shell connected to the base, a liftable middle shell inside the lower shell, a liftable upper shell inside the middle shell, and an infrared detection head mounted on the upper shell.

[0008] A rotating disk is rotatably connected to the middle of the base via a rotating ring. A wedge-shaped locking plate is fixedly connected to the upper end of the rotating disk. A wedge-shaped locking block is fixedly connected to the lower end of the inner wall of the lower shell. The wedge-shaped locking plate abuts against the wedge-shaped locking block.

[0009] The upper part of the lower shell is rotatably connected to three support legs, and the middle part of the lower end of each of the three support legs is rotatably connected to a push rod. The other end of each of the three push rods is rotatably connected to the outer wall of the base.

[0010] A connecting rod is fixedly connected to the upper end of the outer wall of the upper shell. A male interface is provided on one side of the connecting rod. A steel ball is provided inside the connecting rod. A female interface is provided on one side of the outer wall of the infrared detection head. A connecting cover is fixed to the outside of the female interface on the infrared detection head. A groove is provided at the upper end of the connecting cover.

[0011] The above technical solution uses a threaded cylinder, a limit block, and a limit plate to lock the lifting height. It also uses a wedge plate, wedge block, and support leg to achieve stable support and folding storage. The connecting cover and steel ball structure enable quick assembly and disassembly of the detection head, which significantly improves the stability, adjustment efficiency, and ease of operation of the device.

[0012] Furthermore, the upper ends of the outer walls of the lower shell and the middle shell are both threaded with threaded cylinders. The upper end of the threaded cylinder is provided with a through groove. A limit block is fixedly connected to one side of the through groove on the threaded cylinder. The inner walls of the lower shell and the middle shell are both provided with sliding grooves. The outer walls of the middle shell and the upper shell are fixedly connected with limit blocks. The limit block is engaged between two adjacent limit blocks.

[0013] Through the above technical solution, rotating the threaded cylinder can drive the limit block to rotate, causing it to engage between two adjacent limit blocks, thereby mechanically limiting the lifting position of the middle shell and the upper shell, realizing stable locking after the equipment height is adjusted, and significantly improving the structural stability and vibration resistance of the device during the testing process.

[0014] Furthermore, a second spring is connected to the upper end of the connecting rod, a sliding block is fixedly connected to one end of the second spring, a pressure plate is fixedly connected to one side of the sliding block, and the steel ball is located below the pressure plate;

[0015] Through the above technical solution, the second spring can push the sliding block and the pressure plate to move laterally, and use the pressure plate to form a radial limit on the steel ball, thereby preventing the steel ball from moving upward and ensuring that the connection structure is locked firmly.

[0016] Furthermore, the connecting cover is inserted into the connecting rod, the steel ball is engaged in the groove, and the pressure plate is pressed against the upper end of the steel ball;

[0017] With the above technical solution, when the connecting cover is inserted, the squeezed steel ball moves radially against the friction force. After the steel ball is aligned with the groove, it is locked in place. Then, under the lateral thrust of the second spring, the upper end of the steel ball is pressed by the pressure plate to prevent it from resetting and moving upward, thereby realizing the rapid installation and stable locking of the infrared detection head.

[0018] Furthermore, a connecting block is fixedly connected to the outer wall of the rotating ring, a spring is connected to one side of the connecting block, and the other end of the spring is fixedly connected to the base;

[0019] Through the above technical solution, spring one can provide the torque required for the rotating ring to rotate and reset. When the external driving force is removed, the elastic force of spring one will automatically drive the rotating ring and connecting block to reset, preparing for the next unlocking or locking.

[0020] Furthermore, when the threaded cylinder rotates, the through groove connects with the sliding groove;

[0021] By using the above technical solution, the through groove and the sliding groove are aligned and connected by rotating the threaded cylinder, eliminating the blocking effect of the limit block on the limit block, thereby removing the lifting restriction on the middle shell or the upper shell, and facilitating the free adjustment of the equipment height.

[0022] Furthermore, a guide frame is fixedly connected to the outer wall of the lower shell, and a guide plate that slides with the guide frame is fixedly connected to the rotating disk;

[0023] Through the above technical solution, the guide plate can accurately guide and limit the translation trajectory of the base by sliding along the guide frame, avoiding the base from deviating during translation and improving the accuracy of the wedge plate and wedge block engagement.

[0024] Furthermore, the lower end of the rotating disk has three finger holes;

[0025] Through the above technical solution, the finger hole provides users with an easy operating point to apply force. Users can insert their fingers to drive the rotating disk to rotate, thereby easily completing the storage action of the support leg and improving the user experience of the device.

[0026] This invention provides an adjustable single-beam PCB rapid diagnostic instrument. It has the following beneficial effects:

[0027] 1. This invention provides an adjustable single-beam PCB rapid diagnostic instrument. By rotating the threaded cylinder, the limiting block is driven to engage between adjacent limiting blocks, thereby fixing the lifting positions of the lower shell, middle shell, and upper shell through mechanical hard limiting. This achieves stable locking after the device height is adjusted, significantly improving the structural stability and vibration resistance of the device during the testing process.

[0028] 2. This invention provides an adjustable single-beam PCB rapid diagnostic instrument. Through the cooperation between the wedge-shaped plate on the rotating disk and the wedge-shaped block in the lower shell, and the linkage between the support leg and the push rod, stable support is achieved when the device is unfolded. By rotating the rotating ring, the wedge-shaped plate is disengaged from the wedge-shaped block, and then the elastic force of the spring is used to rotate it back to its original position, realizing the rapid folding and storage of the support leg. This significantly improves the stability of the device support and the convenience of folding and storage.

[0029] 3. This invention provides an adjustable single-beam PCB rapid diagnostic instrument. By inserting a connecting cover into a connecting rod and engaging steel balls in a groove and pressing with a pressure plate, it forms an automatically locking quick-release connection structure under the action of a spring, enabling rapid installation and disassembly of the infrared detection head, significantly improving the efficiency of equipment inspection and maintenance and the ease of operation.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] like Figure 1-8 As shown, this embodiment of the invention provides an adjustable single-light PCB rapid diagnostic instrument, including a base 1, a liftable lower shell 2 connected to the base 1, a liftable middle shell 3 inside the lower shell 2, a liftable upper shell 4 inside the middle shell 3, and an infrared detection head 5 installed on the upper shell 4.

[0043] A rotating disk 11 is rotatably connected to the middle of the base 1 via a rotating ring 12. A wedge-shaped card plate 14 is fixedly connected to the upper end of the rotating disk 11. A wedge-shaped card block 23 is fixedly connected to the lower end of the inner wall of the lower shell 2. The wedge-shaped card plate 14 and the wedge-shaped card block 23 abut against each other.

[0044] Three support legs 21 are rotatably connected to the upper part of the outer shell 2. Push rods 22 are rotatably connected to the middle of the lower end of each of the three support legs 21. The other end of each of the three push rods 22 is rotatably connected to the outer wall of the base 1.

[0045] A connecting rod 41 is fixedly connected to the upper end of the outer wall of the upper shell 4. A male interface 46 is provided on one side of the connecting rod 41. A steel ball 45 is provided inside the connecting rod 41. A female interface 51 is provided on one side of the outer wall of the infrared detection head 5. A connecting cover 52 is fixed on the outside of the female interface 51 on the infrared detection head 5. A groove 53 is provided at the upper end of the connecting cover 52.

[0046] The lifting height is locked by the threaded cylinder 6, the limiting block 62 and the limiting block 63. Stable support and folding storage are achieved by the linkage of the wedge plate 14, the wedge block 23 and the support leg 21. The quick assembly and disassembly of the detection head are achieved through the connecting cover 52 and the steel ball 45 structure, which significantly improves the stability, adjustment efficiency and operation convenience of the device.

[0047] Both the lower shell 2 and the middle shell 3 have threaded cylinders 6 threaded to their upper outer walls. The upper end of the threaded cylinder 6 has a through groove 61. A limit block 62 is fixedly connected to one side of the through groove 61 on the threaded cylinder 6. The inner walls of both the lower shell 2 and the middle shell 3 have sliding grooves 64. Limit blocks 63 are fixedly connected to the outer walls of the middle shell 3 and the upper shell 4. The limit block 62 engages between two adjacent limit blocks 63. Rotating the threaded cylinder 6 drives the limit block 62 to rotate, causing it to engage between two adjacent limit blocks 63. This mechanically limits the lifting position of the middle shell 3 and the upper shell 4, achieving stable locking after equipment height adjustment. This significantly improves the structural stability and vibration resistance of the device during the testing process. The inner surface of the connecting rod 41... A second spring 42 is connected to one end of the connecting rod 41. A sliding block 43 is fixedly connected to one end of the second spring 42. A pressure plate 44 is fixedly connected to one side of the sliding block 43. The steel ball 45 is located below the pressure plate 44. The second spring 42 can push the sliding block 43 and the pressure plate 44 to move laterally. The pressure plate 44 forms a radial limit on the steel ball 45, thereby preventing the steel ball 45 from moving upward and ensuring that the connection structure is locked firmly. The connecting cover 52 is inserted into the connecting rod 41. The steel ball 45 is engaged in the groove 53. The pressure plate 44 presses against the upper end of the steel ball 45. When the connecting cover 52 is inserted, it squeezes the steel ball 45 to overcome friction and move radially. After the steel ball 45 is aligned with the groove 53, it is engaged. Then, under the lateral thrust of the second spring 42, the pressure plate 44 presses the steel ball tightly. At the upper end of 45, to prevent it from resetting upwards, thus achieving quick installation and stable locking of the infrared detection head 5, a connecting block 16 is fixedly connected to the outer wall of the rotating ring 12. A spring 17 is connected to one side of the connecting block 16, and the other end of the spring 17 is fixedly connected to the base 1. The spring 17 can provide the torque required for the rotating ring 12 to rotate and reset. When the external driving force is removed, the elastic force of the spring 17 automatically drives the rotating ring 12 and the connecting block 16 to reset, preparing for the next unlocking or locking. When the threaded cylinder 6 rotates, it connects to the sliding groove 64 through the groove 61. By rotating the threaded cylinder 6, the groove 61 and the sliding groove 64 are aligned and connected, eliminating the blocking effect of the limit block 62 on the limit block 63. This removes the lifting restrictions on the middle shell 3 or the upper shell 4, allowing for free height adjustment of the equipment. A guide frame 24 is fixedly connected to the outer wall of the lower shell 2, and a guide plate 13 that slides along the guide frame 24 is fixedly connected to the rotating disk 11. The guide plate 13 slides along the guide frame 24 to accurately guide and limit the translation trajectory of the base 1, preventing the base 1 from shifting during translation and improving the accuracy of the engagement between the wedge-shaped card plate 14 and the wedge-shaped card block 23. Three finger holes 15 are provided at the lower end of the rotating disk 11, providing users with convenient operating points for applying force. Users can insert their fingers to rotate the rotating disk 11, thereby easily completing the storage action of the support leg 21 and improving the user experience of the device.

[0048] Working principle: In use, the support leg 21 is first unfolded. During this process, the wedge-shaped locking plate 14 on the rotating disk 11 gradually engages with the wedge-shaped locking block 23 inside the lower shell 2, locking the support leg 21. When it needs to be folded away, the user rotates the rotating ring 12. The rotating ring 12 compresses the spring 17 through the connecting block 16, causing the wedge-shaped locking plate 14 to rotate and disengage from the wedge-shaped locking block 23. At this time, the support leg 21 loses its locking restriction and can be quickly folded away for storage. After releasing the rotating ring 12, the spring 17 releases its elasticity, causing the rotating ring 12 and the wedge-shaped locking plate 14 to automatically rotate and reset, preparing for the next locking.

[0049] Secondly, adjust the equipment height according to the testing requirements. Rotate the threaded cylinder 6 relative to the lower shell 2 or the middle shell 3 until the through groove 61 on the threaded cylinder 6 connects with the sliding groove 64 on the inner wall. At this point, the limiting block 62 rotates with the threaded cylinder 6 to align with the sliding groove 64, releasing the obstruction of the limiting block 63, allowing the upper shell 4 and the middle shell 3 to rise and fall freely along the sliding groove 64. After adjusting to the appropriate height, rotate the threaded cylinder 6 in the opposite direction to engage the limiting block 62 between two adjacent limiting blocks 63. This mechanical hard-limiting method rigidly fixes the positions of the upper shell 4 and the middle shell 3, effectively eliminating misalignment, preventing shaking during testing, and ensuring testing accuracy.

[0050] Finally, the infrared detection head 5 is quickly installed. The connecting cover 52 is inserted into the connecting rod 41, pushing the steel ball 45 during insertion. When the steel ball 45 aligns with the groove 53 on the connecting cover 52, the lateral force of the second spring 42 pushes the sliding block 43 and the pressure plate 44 to move laterally, causing the pressure plate 44 to press tightly against the upper end of the steel ball 45. The pressure plate 44 radially limits the steel ball 45, preventing it from moving upwards, thus firmly confining the steel ball 45 within the groove 53, forming an automatically locking quick-release structure, achieving a stable connection and rapid disassembly / removal of the head.
