Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a novel automatic detection device for the cutting quality of PCB depaneling machines. Background Technology

[0002] In the PCB manufacturing process, the depaneling stage is crucial. The quality of the cut directly affects the electrical performance, mechanical strength, and overall reliability of the PCB. The quality of the cut after depaneling is vital for subsequent assembly processes and the overall quality of the electronic product. Burrs, cracks, unevenness, and other defects in the cut can lead to poor component soldering, short circuits, open circuits, and other malfunctions, thus affecting the stability and lifespan of the electronic product. Therefore, accurate and efficient inspection of the PCB depaneling machine's cut quality is an indispensable part of the electronic manufacturing process.

[0003] Most PCB depaneling machine cut quality inspection devices on the market can only inspect the cut from a fixed angle. However, in the actual depaneling process, due to factors such as wear of the depaneling tool, differences in depaneling parameter settings, and the characteristics of the PCB material itself, cut quality problems may occur at different angles and positions. A single inspection angle cannot comprehensively and accurately reflect the true quality of the cut, which can easily lead to the omission of some potential quality problems, thereby affecting the overall quality of electronic products. Therefore, this utility model provides a new type of automatic PCB depaneling machine cut quality inspection device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a novel automatic detection device for the cut quality of PCB depaneling machines. This device solves the problem that a single detection angle cannot comprehensively and accurately reflect the true quality of the cut, which can easily lead to the omission of some potential quality issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel automatic detection device for the cutting quality of a PCB depaneling machine, comprising a main body, wherein the main body is provided with a mounting mechanism for automatic detection of the cutting quality of the PCB depaneling machine, the mounting mechanism comprising:

[0006] The clamping assembly includes a support base fixed to the upper end of the main body of the device, a pair of support blocks fixed to the upper surface of the support base, a support shaft rotatably connected inside the support blocks, an installation platform fixed to the outer wall of the support shaft, and installation plates connected by a telescopic assembly on both sides of the upper surface of the installation platform. Clamping plates are attached to the inner wall of the installation plates, and rubber bolts are evenly fixed to the inner wall of the clamping plates.

[0007] The adjustment assembly includes toothed blocks that are uniformly fixed to the outer wall of one end of the support shaft. A positioning slide rail is fixed to the upper end face of the support base. A gear plate connected to the inner wall of the positioning slide rail via a push assembly is provided. The upper end face of the gear plate is meshed with the toothed blocks.

[0008] Preferably, the telescopic assembly includes fixed plates fixed on both sides of the upper surface of the mounting platform, a first electric push rod is fixedly fixed inside the fixed plate, and the mounting plate is fixedly connected to the telescopic end of the first electric push rod.

[0009] Preferably, the mounting plate has six sets of bolts inside, the clamping plate is detachably connected by the bolts of the mounting plate, and the upper end face of the mounting platform has a pair of guide grooves for the sliding of the clamping plate.

[0010] Preferably, the jacking assembly includes a second electric push rod fixed to the upper end face of the support base, a connecting block fixed to the telescopic end of the second electric push rod, and the gear plate fixedly connected to the side wall of the connecting block.

[0011] Preferably, the inner wall of the main body of the equipment is evenly distributed with lighting lamps, the output end of the lighting lamps is aligned with the mounting platform, and the main body of the equipment is equipped with a display screen.

[0013] Beneficial effects

[0014] This invention provides a novel automatic detection device for the cutting quality of PCB depaneling machines. Compared with existing technologies, it has the following advantages:

[0015] Firstly, the telescopic end of the second electric push rod of this utility model drives the connecting block to move, and the connecting block pushes the gear plate to slide in the positioning slide rail. Since the upper end face of the gear plate is meshed with the tooth block on the outer wall of one end of the support shaft, the movement of the gear plate will drive the tooth block to rotate, thereby causing the support shaft to rotate, realizing the adjustment of the installation platform angle. This allows for flexible adjustment of the installation platform angle, enabling the PCB board cut to be presented to the detection probe at different angles, meeting the multi-angle detection requirements, and ensuring comprehensive and accurate detection of the PCB board cut quality.

[0016] Secondly, this utility model achieves the clamping and fixing of the PCB board by tightly fitting the rubber bolts on the inner wall of the clamp. The rubber bolts that are evenly fixed on the inner wall of the clamp can increase the friction with the PCB board, prevent the PCB board from moving or shaking during the testing process, and ensure the accuracy of the testing. At the same time, the clamp is detachably connected to the mounting plate by bolts, which makes it convenient to replace the appropriate clamp according to different sizes or types of PCB boards, thus improving the versatility of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a novel automatic detection device for the cutting quality of a PCB depaneling machine, comprising a main body 1, on which a mounting mechanism for automatic detection of the cutting quality of the PCB depaneling machine is provided, the mounting mechanism comprising:

[0025] The clamping assembly includes a support base 2 fixed to the upper end of the main body 1 of the equipment, a pair of support blocks 201 fixed to the upper end face of the support base 2, a support shaft 202 rotatably connected inside the support block 201, an installation platform 203 fixed to the outer wall of the support shaft 202, and installation plates 302 connected by telescopic components on both sides of the upper end face of the installation platform 203. Clamping plates 304 are attached to the inner wall of the installation plate 302, and rubber bolts 305 are evenly fixed to the inner wall of the clamping plate 304.

[0026] The adjustment assembly includes a toothed block 204 that is uniformly fixed to the outer wall of one end of the support shaft 202. A positioning slide rail 205 is fixed to the upper end face of the support base 2. A gear plate 206 connected by a push assembly is provided on the inner wall of the positioning slide rail 205. The upper end face of the gear plate 206 is meshed with the toothed block 204.

[0027] In a preferred embodiment, the telescopic assembly includes fixed plates 3 fixed on both sides of the upper surface of the mounting platform 203. A first electric push rod 301 is fixedly fixed inside the fixed plate 3. The mounting plate 302 is fixedly connected to the telescopic end of the first electric push rod 301. Six sets of bolts 303 are provided inside the mounting plate 302. The clamping plate 304 is detachably connected through the bolts 303 of the mounting plate 302. A pair of guide grooves 306 for sliding of the clamping plate 304 are provided on the upper surface of the mounting platform 203. When the PCB board is installed, the PCB board is vertically installed between the two sets of clamping plates 304, and the cut position at the top of the PCB board is directly below the detection probe 504.

[0028] The first electric push rod 301 is activated, and its telescopic end pushes the mounting plate 302, causing the clamping plate 304 to move towards the PCB board until the rubber bolts 305 on the inner wall of the clamping plate 304 are tightly fitted to the PCB board, thus completing the clamping and fixing of the PCB board. The rubber bolts 305, which are evenly fixed on the inner wall of the clamping plate 304, can increase the friction with the PCB board and prevent the PCB board from moving or shaking during the testing process, ensuring the accuracy of the testing. At the same time, the clamping plate 304 is detachably connected to the mounting plate 302 by bolts 303, which makes it convenient to replace the appropriate clamping plate 304 according to different sizes or types of PCB boards, thus improving the versatility of the device.

[0029] The guide groove 306 on the upper surface of the mounting platform 203 provides guidance for the movement of the clamping plate 304, making the movement of the clamping plate 304 more stable and further improving the stability of clamping.

[0030] In a preferred embodiment, the push assembly includes a second electric push rod 208 fixed to the upper surface of the support base 2. A connecting block 207 is fixed to the telescopic end of the second electric push rod 208. A gear plate 206 is fixedly connected to the side wall of the connecting block 207. When it is necessary to adjust the angle of the mounting platform 203, the second electric push rod 208 is activated. The telescopic end of the second electric push rod 208 drives the connecting block 207 to move. The connecting block 207 pushes the gear plate 206 to slide within the positioning slide rail 205. Since the upper surface of the gear plate 206 is meshed with the toothed block 204 on the outer wall of one end of the support shaft 202, the movement of the gear plate 206 will drive the toothed block 204 to rotate, thereby causing the support shaft 202 to rotate, thus realizing the adjustment of the angle of the mounting platform 203. This allows for flexible adjustment of the angle of the mounting platform 203, enabling the PCB board cut to be presented to the detection probe 504 at different angles, meeting the multi-angle detection requirements, and ensuring comprehensive and accurate detection of the PCB board cut quality.

[0031] In a preferred embodiment, lighting lamps 4 are evenly distributed on the inner wall of the main body 1. The output ends of the lighting lamps 4 are aligned with the mounting platform 203. The main body 1 is equipped with a display screen 7. A transmission belt 5 is installed on the upper end of the main body 1, directly above the mounting platform 203. A detection base 501 is fixed to the upper end of the transmission belt 5. A third electric push rod 502 is fixed through the inside of the detection base 501. A connecting seat 503 is fixed to the lower end of the third electric push rod 502. A detection probe 504 is installed at the lower end of the connecting seat 503. A slot 6 is formed on the side wall of the connecting seat 503. A locking block 601 is inserted, and a protective shell 602 for protecting the detection probe 504 is fixed to one end of the locking block 601. During the detection, the lighting lamp 4 on the inner wall of the main body 1 is lit to provide sufficient light for the detection. The third electric push rod 502 is activated. The telescopic end of the third electric push rod 502 drives the connecting seat 503 and the detection probe 504 to move downward to detect the top cut of the PCB board. During the detection process, the transmission belt 5 can drive the detection base 501, the third electric push rod 502, the connecting seat 503 and the detection probe 504 to move, so as to realize the detection of different positions of the PCB board cut.

[0032] After the test is completed, the test data is transmitted to the main unit 1 of the equipment and displayed on the display screen 7, allowing operators to easily view the test results.

[0033] When not performing tests or when the equipment is idle, insert the locking block 601 of the protective housing 602 into the slot 6 on the side wall of the connector 503 to protect the detection probe 504 from damage such as impacts and dust. When the detection probe 504 needs to be used, simply pull the locking block 601 out of the slot 6 to remove the protective housing 602.

[0034] The detection probe 504 integrates a high-resolution industrial camera, which can clearly capture images of the PCB board cuts and then transmit them to the display screen 7 for further observation. The industrial camera is a Baslerac A2040-90um model, which can clearly capture the subtle features of the PCB board cuts.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] When using this new type of PCB depaneling machine with automatic cut quality detection device, first place the PCB board vertically between the two sets of clamping plates 304, start the first electric push rod 301, its telescopic end pushes the mounting plate 302, so that the clamping plate 304 moves towards the PCB board until the rubber bolt 305 on the inner wall of the clamping plate 304 is tightly attached to the PCB board, and the clamping and fixing are completed. The guide groove 306 on the upper end face of the mounting platform 203 guides the movement of the clamping plate 304 to ensure the stability of the clamping.

[0037] If the angle of the installation platform 203 needs to be adjusted, the second electric push rod 208 is activated. Its telescopic end drives the connecting block 207 to move. The connecting block 207 pushes the gear plate 206 to slide in the positioning slide rail 205. Because the gear plate 206 meshes with the tooth block 204 on the support shaft 202, it drives the support shaft 202 to rotate to achieve angle adjustment.

[0038] During testing, the lighting lamp 4 on the inner wall of the main body 1 illuminates to provide sufficient light. The third electric push rod 502 is activated, and its telescopic end drives the connecting seat 503 and the detection probe 504 to move downward to detect the top cut of the PCB board. During the testing process, the transmission belt 5 drives the relevant components to move to achieve detection at different positions of the cut. After the test is completed, the test data is transmitted to the main body 1 and displayed on the display screen 7. When not testing or when the equipment is idle, the locking block 601 of the protective shell 602 is inserted into the slot 6 on the side wall of the connecting seat 503 to protect the detection probe 504. When in use, the locking block 601 is pulled out and the protective shell 602 is removed.
