Description

Technical Field

[0001] This invention relates to the field of electronic manufacturing technology, specifically to a PCB and housing matching detection device based on deep learning. Background Technology

[0002] Against the backdrop of the rapid development of the electronics manufacturing industry towards miniaturization, high density, and high precision, PCBs, as the core carrier components of electronic devices, directly determine the structural stability, electrical performance reliability, and appearance consistency of products through their assembly and matching accuracy with the housing. They are widely used in key fields such as consumer electronics, industrial control, automotive electronics, and aerospace. With the increasing functional integration of electronic devices, the structural design of PCBs and housings is becoming increasingly complex. The requirements for testing matching indicators such as hole alignment, dimensional adaptation, and gap control are constantly rising. Traditional methods relying on manual visual inspection or simple mechanical inspection are no longer sufficient to meet the efficiency and accuracy demands of large-scale production. Deep learning technology, with its outstanding advantages in adapting to complex scenarios, provides an intelligent solution for PCB and housing matching inspection. It can achieve automated, high-precision identification and judgment of multi-dimensional matching parameters during the assembly process, aligning with the modern electronics manufacturing industry's trend towards intelligent, efficient, and high-quality production upgrades. This has become a key technological support for ensuring product assembly quality and improving production efficiency.

[0003] Currently, conventional PCB and housing matching testing devices require multiple devices to perform several steps, such as positioning hole alignment testing, dimensional accuracy testing, and electrical connection testing, when matching and testing the PCB board and housing. During this process, the PCB board and its housing need to be moved multiple times, resulting in a cumbersome overall process and inefficiency.

[0004] To address this, a deep learning-based PCB and housing matching detection device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a PCB and housing matching detection device based on deep learning, so as to solve the problem of cumbersome PCB and housing matching detection process mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a PCB and housing matching detection device based on deep learning, comprising a testing body; Match the test assembly structure, set at least one, and position it on the test machine platform through the positioning component; The matching test assembly structure includes a platform. The surface of the platform supporting the PCB board has a groove that adapts to the PCB. Multiple through holes are integrally formed inside the platform at positions corresponding to the PCB and the internal plastic pillars of the housing. An isolation sleeve and an induction coil assembly are fixedly installed inside these through holes at one end near the adaptation groove and the other end away from the adaptation groove, respectively. The isolation sleeve is rigidly connected to the induction coil assembly by reducing its diameter. An inner spacer is inserted at the same height inside the reducing diameter tube of the isolation sleeve. A package is slidably connected to the upper part of the inner spacer and the upper part of the isolation sleeve. The lower end of the package is elastically supported within the inner spacer tube by a first spring. The package is specifically designed to have an induction heat pipe fixedly inserted inside. A through rod is movably inserted into the induction heat pipe without contact with the package. The through rod extends downwards into a driving liquid pipe inserted below the induction coil assembly and is connected and fixed to a piston that slides within the driving liquid pipe. The upper end of the through rod protrudes from the package and is rigidly connected to a dart-shaped demolding top plate. The driving liquid pipe is connected to a linkage liquid pipe via a pipeline. A piston rod, driven by hydraulic pressure, is elastically connected to the side of the linkage liquid pipe away from the hydraulic top, via a third spring. The piston rod extends along the diameter of the linkage liquid pipe and is inserted into a hole on the surface of the hydraulic top output rod.

[0007] Preferably, the platform is connected to the assembly frame through the sliding fit between the corner guide sleeve and the guide post, and the platform is supported by an electrical testing station at fixed intervals below the support column. The electrical testing station is bolted to the surface of the assembly frame. The surface of the electrical testing station near the platform is equipped with multiple test probes for electrical testing according to the PCB to be tested. The surface of the platform has through holes that allow the test probes to pass through the electrical testing points of the PCB.

[0008] Preferably, the induction coil transmission ring of the induction coil assembly is sleeved on the variable diameter tube body of the isolation sleeve.

[0009] Preferably, the surface of the package has multiple windows open to the induction heat pipe within the area where the induction heat pipe is located, and the upper end of the induction heat pipe is exposed on the upper surface of the package, but not flush with the surface of the package.

[0010] Preferably, the lower end of the through rod is elastically limited inside the driving liquid tube by a second spring, and the lower end of the driving liquid tube protrudes out of the induction coil assembly, and the protruding end of the driving liquid tube is provided with a liquid circulation interface.

[0011] Preferably, the upper surface of the isolation sleeve and the package is flush with the bottom surface of the adapter groove of the PCB on the platform, and the linkage liquid pipe is pushed up and embedded in the groove set on the lower surface of the mounting plate on the assembly frame.

[0012] Preferably, the hydraulic jack is bolted to the surface of the mounting plate on the assembly frame. The assembly frame is connected to a slide table above the platform via guide posts and guide sleeves. The upper surface of the slide table is bolted to the output end of the hydraulic jack, and the lower surface of the slide table is bolted to a reciprocating linear module. The reciprocating linear module includes a drive mechanism that provides power, a transmission component that transmits motion, a guide rail slider mechanism that ensures guiding accuracy, a slide table that bears the load, a frame that provides the mounting base, and auxiliary limit / detection elements. The surface of the slide table is bolted to an electric actuator, and the output end of the electric actuator is equipped with a vacuum suction cup for adsorbing the outer casing.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a hydraulic linkage locking mechanism consisting of a driving liquid pipe, a linkage liquid pipe and a piston rod to release the hydraulic top lock only when the plastic column of the outer shell is successfully aligned with the hole of the PCB board, thereby realizing the automated judgment of matching detection and reducing the risk of misjudgment caused by manual intervention. 2. By setting up an electrical testing station and test probes, this invention can simultaneously perform electrical function testing on the PCB board while matching testing with the casing. This eliminates the need for additional separate electrical testing procedures, saving the PCB board from the transfer process between matching and electrical testing, shortening the overall testing time, and avoiding potential damage to the PCB board due to secondary transfer. It achieves simultaneous completion of matching and electrical testing, significantly improving testing efficiency and the integrity of product quality control. 3. This invention utilizes the linkage and conduction of induction coil assembly, metal induction heat pipe and demolding top plate to achieve softening and riveting of plastic columns through rapid heating by electromagnetic induction. At the same time, the riveting forming state is used to verify the hole alignment accuracy, taking into account both assembly and matching inspection needs, and enhancing the comprehensiveness of inspection. 4. This invention integrates matching testing, electrical testing, and thermal riveting assembly functions into a single matching test assembly structure, eliminating the need for multiple transfers of the PCB and the casing. This simplifies the traditional decentralized testing process and significantly improves the testing and assembly efficiency in large-scale production. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1 to 8 This invention provides a technical solution for a PCB and housing matching detection device based on deep learning: A deep learning-based PCB and enclosure matching detection device includes: Test body 1, as the basic support structure of the equipment, plays a role in stabilizing and bearing the load for the entire equipment; The matching test assembly structure 2 is provided at least once and is positioned on the table of the test body 1 by the positioning component. It has the functions of matching detection of PCB board and shell, electrical testing of PCB board and thermal riveting assembly of the two. The matching test assembly structure 2 includes a platform 21, which is connected to the assembly frame 23 through the sliding fit of the corner guide sleeve and the guide column. The platform 21 is connected to the support column 212 at fixed intervals below it for electrical testing. The electrical testing table 211 is bolted to the surface of the assembly frame 23. The assembly frame 23 consists of two upper and lower carrier plates and four guide columns connected to the carrier plates. The platform 21, which supports the PCB board, has a groove that fits the PCB. Multiple through holes are integrally formed inside the platform 21 at positions corresponding to the PCB and the internal plastic pillars of the housing. These through holes do not interfere with the supporting pillars 212. An isolation sleeve 2141 and an induction coil assembly 214 are fixedly installed inside these through holes at one end near the adaptation groove and the other end away from the adaptation groove, respectively. The isolation sleeve 2141 is rigidly connected to the induction coil assembly 214 by reducing its diameter. The induction coil transmission ring of the induction coil assembly 214 is sleeved on the reduced-diameter tube of the isolation sleeve 2141. An inner spacer 2142 is inserted at the same height inside the reduced-diameter tube of the isolation sleeve 2141. An I-shaped package 2143 is slidably connected to the upper part of the inner sleeve 2142 and the upper part of the inner sleeve 2141. The lower end of the package 2143 is elastically limited within the inner sleeve 2142 tube by a first spring 2144. A metal induction heat pipe 2145 is inserted and fixedly installed inside the package 2143. Multiple windows are provided on the surface of the package 2143 within the area of ​​the induction heat pipe 2145, and the upper end of the induction heat pipe 2145 is exposed on the upper surface of the package 2143, but not flush with the surface of the package 2143. A through rod 2147 is movably inserted and inserted into the inside of the package 2143 without contacting the induction heat pipe 2145. The rod passes through the induction heat pipe 2145, the package 2143, and the first spring 2144 from top to bottom into the driving liquid pipe 2149 inserted below the induction coil assembly 214. It is then connected and fixed to a piston that slides within the driving liquid pipe 2149. The lower end of the through rod 2147 is elastically limited within the driving liquid pipe 2149 by the second spring 2148. The lower end of the driving liquid pipe 2149 protrudes from the induction coil assembly 214, and its exit end has a liquid circulation interface. The interface on the side of the driving liquid pipe 2149, after being connected through pipe integration and convergence, connects upwards to the interface on the side of the linkage liquid pipe 231 near the hydraulic top 24. The linkage liquid pipe 231 is pushed upwards... The hydraulic jack 24 is embedded in a groove on the lower surface of the upper plate of the assembly frame 23. A piston rod 233, driven by hydraulic pressure, is elastically connected to the side of the linkage liquid pipe 231 away from the hydraulic jack 24, in conjunction with a third spring 232. The piston rod 233 passes through the diameter of the linkage liquid pipe 231 and is inserted into a hole on the surface of the output rod of the hydraulic jack 24, thereby locking the hydraulic jack 24. The hydraulic jack 24 is bolted to the surface of the upper plate of the assembly frame 23. Above the platform 21, the assembly frame 23 has a slide 22 connected via guide posts and guide sleeves. The upper surface of the slide 22 is bolted to the output end of the hydraulic jack 24, and the lower surface of the slide 22 is bolted to the reciprocating linear module 221.The reciprocating linear module 221 includes a drive mechanism providing power, a transmission component for motion transmission, a guide rail slider mechanism to ensure guiding accuracy, a slide table to bear the load, a frame to provide a mounting base, and auxiliary limit / detection elements. An electric actuator 222 is bolted to the surface of the slide table, and the output end of the electric actuator 222 is equipped with a vacuum suction cup 223 for adsorbing the outer casing. The lower part of the induction coil assembly 214 is electrically connected to the test body 1 via a plug-in structure. The drive fluid pipe 2149 stores safe fluids such as hydraulic oil.

[0018] During operation, the PCB board is precisely placed in the adapter slot of the stage 21 and makes corresponding contact with the test probe 213. The reciprocating linear module 221 drives the electric push rod 222 and the vacuum suction cup 223 to pick up the outer shell and move it to the top of the PCB board to complete the alignment. The plastic column of the outer shell pushes the dart-shaped demolding top plate 2146 of the stage 21, pushes the through rod 2147 down and compresses the second spring 2148, so that the liquid in the drive liquid pipe 2149 is pressurized and flows into the linkage liquid pipe 231, thereby pushing the piston rod 233 out of the output rod insertion hole of the hydraulic top 24 to release the lock. If the plastic column cannot be inserted and connected with the hot riveting hole of the PCB board, the device resets and performs batch testing.

[0019] In summary, by setting up a hydraulic linkage locking mechanism consisting of drive liquid pipe 2149, linkage liquid pipe 231 and piston rod 233, the hydraulic top 24 is only released when the outer plastic column and the PCB board hole are successfully aligned, thus realizing automated judgment of matching detection and reducing the risk of misjudgment caused by manual intervention.

[0020] As one embodiment of the present invention, such as Figures 1 to 4 As shown, the surface of the electrical testing station 211 near the stage 21 is equipped with multiple test probes 213 for electrical testing according to the PCB to be tested, and the surface of the stage 21 has through holes that allow the test probes 213 to pass through the electrical testing points of the PCB.

[0021] During operation, the hydraulic top 24 is activated, driving the slide 22 to move the outer shell continuously downward. The outer shell and the PCB board are gradually assembled and moved downward in sync under continuous downward pressure. When the PCB board moves down to make close contact with the test probe 213 protruding from the stage 21, the electrical testing stage 211 will cooperate with the test probe 213 to conduct electrical function tests on the PCB board through the conduction between the probe and the electrical testing point on the PCB board.

[0022] In summary, by setting up the electrical testing station 211 and the test probe 213, the electrical function test of the PCB can be carried out simultaneously while the PCB and the housing are being matched. There is no need to set up an additional electrical testing procedure. This not only eliminates the PCB transfer step between the matching test and the electrical test, shortening the overall test process time, but also avoids the PCB damage that may be caused by secondary transfer. It achieves simultaneous completion of matching and electrical dual tests, greatly improving test efficiency and the integrity of product quality control.

[0023] As one embodiment of the present invention, such as Figures 5 to 7 As shown, the upper end of the through rod 2147 protrudes above the package 2143 and is rigidly connected to the dart-shaped demolding top plate 2146. The upper surface of the package 2143 has an adapter groove for flush housing the demolding top plate 2146. The upper surfaces of the isolation sleeve 2141 and the package 2143 are flush with the bottom surface of the adapter groove of the PCB on the platform 21.

[0024] During operation, the plastic pillars of the outer shell move downwards and completely press the demolding top plate 2146 into the adapter groove of the package 2143. After continuous pressure is applied, the package 2143 slides down along the inner wall of the isolation sleeve 2141 and the inner partition sleeve 2142. After the induction heat pipe 2145 in the package 2143 moves into the induction coil area, the energized coil heats the metal induction heat pipe 2145 through electromagnetic induction. The heat is conducted through the demolding top plate 2146 to the plastic pillar, which softens it. Under continuous pressure, the softened plastic pillar ends pass through the reserved holes in the PCB board and are squeezed into mushroom heads or flat heads, realizing the rapid thermal riveting and fixing of the outer shell and the PCB board.

[0025] In summary, by linking the induction coil assembly 214, the metal induction heat pipe 2145, and the demolding top plate 2146, electromagnetic induction rapid heating is used to soften and rivet the plastic column. At the same time, the hole alignment accuracy is verified by reverse verification of the riveting forming state, which takes into account both assembly and matching inspection needs and enhances the comprehensiveness of inspection. The matching test assembly structure 2 integrates matching inspection, electrical testing, and thermal riveting assembly functions, eliminating the need for multiple transfers of PCB and shell, simplifying the traditional decentralized inspection process, and greatly improving the inspection and assembly efficiency in large-scale production.

[0026] Working principle: During operation, the PCB board is first precisely placed in the matching slot of the stage 21 with the help of deep learning robotic arms and other equipment, ensuring that the electrical test points of the PCB board are in contact with the test probes 213 protruding from the surface of the stage 21, thus preparing for subsequent electrical testing. Then, the reciprocating linear module 221 is started, which drives the electric push rod 222 and vacuum suction cup 223 connected to its slide 22 to move. The vacuum suction cup 223 will work with the electric push rod 222 to pick up the shell to be tested. Then, through the precise positioning function of the module, the shell is moved to the top of the PCB board on the stage 21 to complete the alignment before testing. Initially, the hydraulic top 24 is locked because the piston rod 233 is inserted into its output rod socket, preventing the slide table 22 from moving downwards. When the housing moves closer to the PCB board and initiates the assembly action under the push of the electric push rod 222, the plastic column inside the housing will first contact the dart-shaped demolding top plate 2146 at the corresponding position of the adapter groove of the platform 21, generating downward pressure. This pressure pushes the through rod 2147 downwards along the cavity of the induction heat pipe 2145, the internal channel of the package 2143, and the central area of ​​the first spring 2144. During this process, the lower end of the through rod 2147 will compress the second spring 2148, and drive the piston in the drive fluid pipe 2149 to move downwards synchronously, causing the drive fluid... After being pressurized, the liquid in pipe 2149 flows through the pipeline and is finally input into the linkage liquid pipe 231. Then, the hydraulic driving force in the linkage liquid pipe 231 will push the piston rod 233 to move away from the hydraulic top 24, while compressing the third spring 232 until the piston rod 233 completely exits the insertion hole of the output rod of the hydraulic top 24, releasing the locking state of the hydraulic top 24. At this stage, if the plastic column of the outer shell cannot be inserted and connected with the hot riveting hole on the surface of the PCB board, so that the plastic column is pushed against the surface of the PCB board, the PCB board cannot perform the above process normally, which means that the PCB and the outer shell have failed to match. The staff can reset the control detection device to perform a batch of outer shell and PCB testing. Subsequently, the hydraulic top 24 is activated, driving the slide 22 to move the outer shell continuously downward. The outer shell and the PCB board gradually complete the fitting assembly, and under the continuous downward pressure, the PCB board is moved downward in sync. When the PCB board moves down to make close contact with the test probe 213 (which has telescopic capability) protruding from the platform 21, the electrical testing platform 211 will cooperate with the test probe 213 to carry out the electrical function test of the PCB board through the conduction between the probe and the electrical testing point of the PCB board. Meanwhile, as the outer shell moves downward, the plastic pillars, after completely pressing the demolding top plate 2146 into the fitting groove on the surface of the package 2143, will continue to apply downward pressure to the package 2143, pushing it to slide downward along the inner walls of the isolation sleeve 2141 and the inner partition sleeve 2142 (during this process, the first spring 2144 is always outside the electromagnetic induction range of the induction coil assembly 214 to avoid being affected by induction heating, and the spring is preferably made of heat-resistant, high-strength non-metallic material). When the induction heat pipe 2145 fixed inside the package 2143 moves to the induction coil area of ​​the induction coil assembly 214, When the induction coil is powered on, it heats the metal induction heat pipe 2145 through electromagnetic induction. The induction heat pipe 2145 quickly conducts heat to the demolding top plate 2146 in contact with it. The demolding top plate 2146 then transfers heat to the plastic pillar of the outer shell, causing the plastic pillar to soften. Under the continuous pressure of the package 2143 and the demolding top plate 2146, the PCB board squeezes the end of the softened plastic pillar, so that the end of the plastic pillar passing through the pre-drilled hole in the PCB board is pressed into a mushroom head or flat head shape, thereby achieving rapid thermal riveting and fixing of the outer shell and the PCB board. After the electrical function test of the PCB board is completed, the hydraulic top 24 starts in reverse, driving the slide 22 to move the vacuum suction cup 223 (still adsorbing the outer shell) and the PCB board that has been thermally riveted to the outer shell synchronously upward. When the slide 22 is completely reset to the initial height, the reciprocating linear module 221 starts again, working with the vacuum suction cup 223 to transfer the assembly of the outer shell and the PCB board to the finished product storage position. During or after the transfer, the matching accuracy of the two can be further judged by observing the thermal riveting points of the PCB board and the outer shell (such as riveting flatness, flatness, whether there is offset, etc.). If a matching deviation is found (such as riveting offset reflecting hole alignment problems), the positioning of the stage 21 or the outer shell design can be adjusted in time. Finally, through the above process, the matching detection of the PCB board and the outer shell, the electrical test of the PCB board, and the thermal riveting assembly of the two are realized in an integrated manner.
