Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and more specifically, it relates to a detection device for multi-layer circuit board processing. Background Art

[0002] With the rapid development of electronic technology, multi-layer circuit boards are increasingly widely used in electronic devices. Due to their complex structure and powerful functions, higher requirements are put forward for quality control in the processing process. In order to ensure the quality and production efficiency of multi-layer circuit boards, it is particularly important to design an efficient and reliable detection device. The technical solution aims to provide a detection device for multi-layer circuit board processing, which can achieve comprehensive and rapid detection of multi-layer circuit boards by integrating various detection technologies.

[0003] During the production process of circuit boards, it is generally necessary to extract a certain number of circuit boards for detection, including the detection of each module inside the circuit board. Manual detection is generally that personnel grab the detection pen of the detection device and connect the detection pen to the detector, and perform connection detection and other operations by touching the detection pen on each joint point on the surface of the circuit board. However, currently, during the use of the detector, the signal transmission line between the detection pen and the detector is generally directly dragged outside. During detection, the exposed and dragged wire is likely to drag on the surface of the circuit board and will affect the detection operation of the detection personnel, and the practicability is poor.

[0004] Therefore, in order to solve the above technical problems, this application proposes a detection device for multi-layer circuit board processing. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a detection device for multi-layer circuit board processing.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: including: a detector for detecting a circuit board:

[0007] It also includes: a detection pen for detecting a circuit board, which is connected to the outside of the detector through a quick-release structure;

[0008] A signal line for signal transmission is connected between the detection pen and the detector;

[0009] The signal line can be telescopically wound in the detector through a wire winding structure.

[0010] In this solution, the quick-release structure includes a clamping plate fixedly installed on the surface of the detector. The bottom of the clamping plate is evenly spaced with multiple slots for detachably inserting the detection pen. A wire passing hole is opened at the bottom end of the slot and penetrates through the clamping plate, and a signal line is movably inserted into the wire passing hole;

[0011] The top end of the detection pen is provided with an insertion block, which is fixedly connected to one end of the signal line. A magnetic strip for magnetically connecting the detection pen and the card board is arranged between the top end of the insertion block and the slot.

[0012] In this embodiment, the wire winding structure includes wire grooves opened on the surface of the detector for the number and position of the detection pens. The bottom end inside the wire groove communicates with a cavity opened inside the detector, and a wire winding roller is rotatably installed in the cavity. One end of the wire winding roller is provided with a bearing, and the other end of the wire winding roller is fixedly connected to one side of a wire winding gear. The other side of the wire winding gear is connected to the inner side wall of the detector through a torsion spring rotating shaft that can self-reset and rotate.

[0013] It should be noted that one side of the wire winding gear is meshed and linked with an adjustment gear. The adjustment gear is installed inside the detector through a torsion spring rotating shaft, and the other side is fixedly connected to a threaded rod for providing the only power source for the slider. And one side of the adjustment gear provided with the torsion spring rotating shaft is connected through a transmission shaft penetrating the middle space of the torsion spring rotating shaft to a turntable for manually rotating the adjustment gear penetrating the outside of the detector. A screw block is arranged at the bottom of the slider threadedly connected to the surface of the threaded rod, and the screw block is slidably connected in a slide rail, and the slide rail is opened at the bottom inside the wire groove.

[0014] Furthermore, the size of the adjustment gear is larger than that of the wire winding gear to realize the adjustment of the position of the slider when winding the signal line and to cooperate with the winding progress of the signal line.

[0015] Wherein, an anti-slip sleeve is sleeved on the surface of the detection pen.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] 1. Improve the detection efficiency: Through the design of the quick-release structure and the wire winding structure, the quick loading and unloading of the detection pen and the automatic winding and unwinding of the signal line are realized, significantly improving the detection efficiency of multi-layer circuit board processing.

[0018] 2. Avoid signal line interference: The signal line can be telescopically wound inside the detector, avoiding the problem that the signal line is dragged outside in the traditional way, which affects the operation of the detection personnel, and ensuring the accuracy and smoothness of the detection.

[0019] 3. Improve the detection accuracy: The anti-slip sleeve sleeved on the surface of the detection pen increases the friction between the hand and the detection pen, making the detection operation more stable and helping to improve the detection accuracy.

[0020] 4. Compact structure and convenient operation: The overall design is compact and the operation is simple, facilitating the detection personnel to carry out fast and accurate detection work at the circuit board processing site.

[0021] 5. Automatic cleaning signal line: The cleaning sponge filled in the slot wipes and cleans the surface of the signal line while retracting and extending the signal line, prolonging the service life of the signal line and maintaining stable signal transmission.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] As Figures 1 - 5 shown, the present invention provides a detection device for multi-layer circuit board processing, including: a detector 1 for detecting a circuit board;

[0030] It further includes: a detection pen 7 for detecting a circuit board, which is connected to the outside of the detector 1 through a quick-release structure;

[0031] A signal line 5 for signal transmission is connected between the detection pen 7 and the detector 1;

[0032] The signal line 5 can be telescopically wound in the detector 1 through a wire winding structure.

[0033] The quick-release structure includes a clamping plate 4 fixedly installed on the surface of the detector 1. Multiple groups of slots 10 for detachably plugging the detection pen 7 are evenly spaced at the bottom of the clamping plate 4. A wire passing hole 9 is opened at the inner bottom end of the slot 10 and penetrates the clamping plate 4. A signal wire 5 is movably plugged in the wire passing hole 9;

[0034] An insertion block 6 is provided at the top end of the detection pen 7. The insertion block 6 is fixedly connected to one end of the signal wire 5. A magnetic strip for magnetically connecting between the detection pen 7 and the clamping plate 4 is provided between the top end of the insertion block 6 and the slot 10.

[0035] The wire winding structure includes wire grooves 2 opened on the surface of the detector 1 according to the quantity and position of the detection pens 7. The inner bottom end of the wire grooves 2 communicates with a cavity opened inside the detector 1. A wire winding roller 11 is rotatably installed in the cavity. A bearing is provided at one end of the wire winding roller 11. The other end of the wire winding roller 11 is fixedly connected to one side of a wire winding gear 12. The other side of the wire winding gear 12 is connected to the inner side wall of the detector 1 through a torsion spring rotating shaft 19 that can self-reset and rotate.

[0036] One side of the wire winding gear 12 is meshed and linked with an adjusting gear 13. The adjusting gear 13 is installed inside the detector 1 through a torsion spring rotating shaft 19 and a threaded rod 14 for uniquely providing power to the slider 15 is fixedly connected to the other side. One side of the adjusting gear 13 provided with the torsion spring rotating shaft 19 is connected to a turntable 20 for manually rotating the adjusting gear 13 through a transmission shaft penetrating the middle space of the torsion spring rotating shaft 19 and penetrating outside the detector 1. A screw block 17 is provided at the bottom of the slider 15 threadedly connected to the surface of the threaded rod 14. The screw block 17 is slidably connected in a slide rail 18. The slide rail 18 is opened at the inner bottom of the wire groove 2.

[0037] The size of the adjusting gear 13 is larger than that of the wire winding gear 12 to realize the adjustment of the position of the slider 15 and cooperate with the winding progress of the signal wire 5 when winding the signal wire 5.

[0038] An anti-slip sleeve 8 is sleeved on the surface of the detection pen 7.

[0039] Working principle: During use, after installing the detector 1 at the required position, when a person is detecting a circuit board, the person grabs the detection pen 7 and pulls it. After the detection pen 7 is pulled out from the slot 10, the detection pen 7 will pull the signal wire 5, and the signal wire 5 is unrolled from the surface of the wire winding roller 11 and drives the wire winding gear 12 to rotate. The wire winding gear 12 drives the engaged adjustment gear 13 to rotate, thereby driving the screw rod to rotate, and then driving the screw block 17 to drive the slider 15 to slide in the slide rail 18, so as to extend the signal wire 5 outwards, and then use the detection pen 7 for detection. During the detection process by the person, the anti-slip sleeve 8 sleeved on the surface of the detection pen 7 can increase the friction with the person's hand, facilitating the person to grab and use for detection. At the same time, after use, the insertion block 6 at the top of the detection pen 7 is inserted into the slot 10 at the bottom of the clamping plate 4. And during the insertion, the torsion spring rotating shaft 19 rotates back to rotate the adjustment gear 13 and the wire winding gear 12, so that the screw block 17 slides in the slide rail 18 as the screw rod rotates, and at the same time drives the slider 15 to arrange the signal wire 5 on the surface of the wire winding roller 11, arranging the signal wire 5 during the wire winding process, and can also pull the signal wire 5 during the detection process. At the same time, the cleaning sponge 3 filled in the slot 10 can wipe and clean the surface of the signal wire 5 while taking in and releasing the signal wire 5, and at the same time will not affect the detection of the circuit board due to the dragging of the signal wire 5 during the detection process. The through hole 16 opened in the slider 15 will pull the signal wire 5 to slide for arrangement.

[0040] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in this industry can smoothly implement the present invention according to the illustrations in the specification and the above description; however, any slight changes, modifications and equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
