Description

Technical Field

[0001] This invention relates to the field of PCB assembly and inspection technology, and in particular to an Internet of Things-based PCB assembly and inspection system. Background Technology

[0002] A PCB, or Printed Circuit Board, is a crucial electronic component. It serves as the support for electronic components, the carrier for electrical connections between them, and a vital part of the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication equipment, and military weaponry, utilizes PCBs to enable electrical interconnection between integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components. It serves the dual purpose of providing conductive traces and acting as an insulating base. PCBs offer excellent product consistency, allowing for standardized designs and facilitating mechanization and automation in the production process.

[0003] The existing PCB assembly inspection system has the following shortcomings: it cannot detect and locate different types of PCBs during assembly, and it cannot locate and provide early warnings for problematic PCBs. Summary of the Invention

[0004] The purpose of this invention is to provide a PCB board assembly and inspection system based on the Internet of Things (IoT). The technical problem to be solved by this invention is: How to solve the problems of existing solutions being unable to detect and locate PCB boards during assembly, and the inability to locate and provide early warnings for problematic areas in detected PCB boards? The purpose of this invention can be achieved through the following technical solution: A PCB board assembly detection system based on the Internet of Things (IoT), comprising a data acquisition module, a data processing module, a data analysis module, a marking module, an early warning module, and a data transmission module; the data acquisition module is used to collect data information of the assembled PCB board, including PCB board type information, size information, and coordinate information; wherein, the size information includes PCB board length data, PCB board width data, and PCB board height data, and the coordinate information includes PCB board body coordinate data and PCB board surface position data; the data information is sent to the data processing module through the data transmission module; the data processing module is used to receive and process the data information to obtain data processing information, and send the data processing information to the data analysis module; wherein, the data processing information includes mark type information, size information, coordinate information, type preset value, coordinate preset value, detection value, and detection data.

[0005] Preferably, the data acquisition module includes an image data acquisition device, which includes a base, a first lifting adjustment device, a second lifting collection device, and an image acquisition device, and a transmission rail is provided on the base. The second lifting collection device is located above one end of the transmission rail and is connected to the first lifting adjustment device. The image acquisition device is located above the first lifting adjustment device.

[0006] Preferably, the first lifting adjustment device includes a fixed base, a drive rod connected to the fixed base, one end of the drive rod connected to a drive motor, and the other end connected to a support base. A lifting adjustment block is provided on the outer side of the support base, and a support block is evenly provided on the outer side of the lifting adjustment block. The support block is inclined at 5-10° and has a positioning cylinder. An auxiliary lifting device is also provided on one side of the fixed base. The auxiliary lifting device is synchronously lifted and lowered with the support base via a drive motor. The auxiliary lifting device matches the support block. A PCB board to be inspected is provided between the auxiliary lifting device and the support base. A guide block is also provided between the auxiliary lifting device and the support base.

[0007] Preferably, the second lifting and collecting device includes an auxiliary lifting device, which is mounted on the first lifting and adjusting device. A drive rod 2 is mounted on one side of the auxiliary lifting device via a fixed base. One end of the drive rod 2 is connected to a drive motor 3, which moves synchronously with the first lifting and adjusting device. A guide block 2 is provided between the auxiliary lifting device and the drive rod 2. A support base is provided at the other end of the drive rod 2.

This facilitates quick location and processing of problematic areas on the PCB board, achieving the goal of locating and providing early warnings for detected problematic areas on the PCB board.

[0010] Due to the angle setting of the support block, this invention ensures that the position of each PCB board to be inspected is consistent before image inspection, thereby reducing errors during image inspection and preventing interference caused by different inspections at different positions. At this time, the setting of the second lifting and collecting device collects the inspected PCB boards and allows all PCB boards to fall into the same position. They are then intermittently transported to the next process via the transport track, which greatly reduces manual labor and ensures the accuracy of inspection and the precision of placement.

[0014] 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.

[0015] An IoT-based PCB assembly and inspection system includes a data acquisition module, a data processing module, a data analysis module, a marking module, an early warning module, and a data transmission module. The data acquisition module collects data information from the assembled PCB, including PCB type information, size information, and coordinate information. The size information includes PCB length, width, and height data, while the coordinate information includes PCB body coordinates and PCB surface position data. The data is then transmitted to the data processing module via the data transmission module. The data processing module receives and processes the data to obtain processed data information, which is then sent to the data analysis module. This processed data information includes mark type information, size information, coordinate information, type preset values, coordinate preset values, detection values, and detection data.

[0016] Specifically, the data acquisition module includes an image data acquisition device, which includes a base 1, a first lifting adjustment device 2, a second lifting collection device 3, and an image acquisition device. A transmission rail 4 is provided on the base 1, and the second lifting collection device 3 is located above one end of the transmission rail 4. The second lifting collection device 3 is connected to the first lifting adjustment device 2, and the image acquisition device is located above the first lifting adjustment device 2.

[0017] Specifically, the first lifting adjustment device 2 includes a fixed base 201, a drive rod 202 connected to the fixed base 201, one end of the drive rod 202 connected to a drive motor 203, and the other end connected to a support base 204. A lifting adjustment block 205 is provided on the outside of the support base 204, and support blocks 206 are evenly arranged on the outside of the lifting adjustment block 205. The support blocks 206 are set at an inclination of 5-10° and a positioning cylinder 207 is provided on the support blocks 206. An auxiliary lifting device 208 is also provided on one side of the fixed base 201. The auxiliary lifting device 208 is synchronously lifted and lowered with the support base 204 through a drive motor 209. The auxiliary lifting device 208 matches the support blocks 206. A PCB board 5 to be inspected is provided between the auxiliary lifting device 208 and the support base 204. A guide block 210 is also provided between the auxiliary lifting device 208 and the support base 204.

[0018] Specifically, the second lifting and collecting device 3 includes an auxiliary lifting device 208, which is mounted on the first lifting and adjusting device 2. A drive rod 302 is mounted on one side of the auxiliary lifting device 208 via a fixed base 201. One end of the drive rod 302 is connected to a drive motor 303, which moves synchronously with the first lifting and adjusting device 2. A guide block 304 is provided between the auxiliary lifting device 208 and the drive rod 302. A support base 204 is provided at the other end of the drive rod 302. A lifting and collecting block 305 is mounted on the support base 204. A support block 306 is mounted on the lifting and collecting block 305. The support block 306 is inclined at 5-10° and has a limit block at its bottom. A transmission track 4 is provided below the support base 204.

[0019] Specifically, the lifting adjustment block 205 and the lifting collection block 305 are made of rubber.

[0020] When the data acquisition device of the present invention is working, drive motor 1 203, drive motor 209, and drive motor 303 start working simultaneously. At this time, the movement frequencies of the first lifting adjustment device 2 and the second lifting collection device 3 are matched, and the PCB board to be inspected 5 is inserted into the push block 1 between the auxiliary lifting device 208 and the support base 204. At this time, due to the different insertion positions each time, the position of each PCB board to be inspected 5 is different. At this time, while the first lifting adjustment device 2 is rising, the guide block 1 is used to correct the position of the PCB board to be inspected 5, ensuring that the PCB board to be inspected 5 can be locked into the positioning cylinder 207 at the end of its upward movement. When the PCB board to be inspected is at the highest position, due to the deformation of the lifting adjustment block 205, the multiple PCB boards to be inspected are distributed in a fan shape. At this time, the image acquisition device collects and compares the image of the PCB board to be inspected in the middle, and transmits the data to the data processing module and the data analysis module.

[0021] The PCB board to be inspected then rotates 180°. At this time, due to the inversion of the PCB board, the PCB board to be inspected will fall out of the positioning cylinder. At the same time, under the guidance of the second guide block, the PCB board to be inspected will move from the first lifting adjustment device to the second lifting collection device. When it moves to the bottom layer, the PCB board to be inspected is exactly above the transmission track, and the falling position of each PCB board to be inspected is the same.

[0022] Due to the angle setting of the first support block, the position of each PCB board to be inspected can be ensured to be consistent before the image inspection of the PCB board. This reduces errors during image inspection and prevents interference caused by different inspections at different positions. At this time, the setting of the second lifting and collecting device collects the inspected PCB boards and allows all PCB boards to fall into the same position. They are then transported to the next process intermittently through the transfer track, which greatly reduces manual labor and ensures the accuracy of inspection and the precision of placement.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
