Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing devices, and particularly relates to a circuit board manufacturing device. Background Art

[0002] Printed circuit boards are essential basic components in electronic devices, used to connect and support electronic components, achieve signal transmission and electrical connection. Its basic composition includes the following parts: substrate, conductive layer, solder pad, via hole, solder mask layer, and silk screen layer.

[0003] According to its number of layers and uses, circuit boards can be divided into single-sided boards, double-sided boards, and multi-layer boards. A single-sided board has conductive traces on only one side and is suitable for simple devices. A double-sided board has traces on both sides and is suitable for complex circuits. A multi-layer board is composed of multiple stacked conductive layers and is used for high-end devices.

[0004] Its manufacturing stage is divided into multiple steps, and its main process is: substrate preparation, lamination and copper foil cladding, photolithography and etching, drilling and pressing, electroplating and surface treatment, silk screen printing of characters and solder mask layer, soldering and assembly, final inspection and packaging.

[0005] Among them, the pressing of circuit boards mainly bonds the layers of materials of multi-layer circuit boards together through high temperature and high pressure to form an integral multi-layer circuit board. This process usually involves the combination of heating and pressure to closely bond the layers of materials and ensure the reliability of electrical connection and mechanical strength.

[0006] Currently, in the process of manufacturing multi-layer circuit boards, a pressing process is required, and generally a circuit board press is used. During the pressing process, it is difficult to fully guarantee the yield of the pressed circuit boards. For example, problems such as material issues and uneven working surfaces are likely to cause problems such as circuit board fracture, bending, inner side cracking, and deformation of metal patches.

[0007] Currently, the fracture problem of circuit boards is likely to leave debris on the pressing machine backing plate. Existing backing plates mostly use manual cleaning methods. Although some can be cleaned, a small amount of debris is difficult to be easily observed by the naked eye, seriously affecting the flatness of the backing plate. Especially on the production line, it is easy to find and solve the problem only after damaging a large number of circuit boards, which greatly reduces the yield of circuit board pressing, causes waste of materials, increases production costs, and is not conducive to long-term use.

[0008] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0018] A cleaning power shaft is installed between the reciprocating cleaning motor and the reciprocating dust suction roller, connecting the reciprocating cleaning motor and the reciprocating dust suction roller, enabling the reciprocating dust suction roller to be driven by the reciprocating cleaning motor, enabling the power of the reciprocating cleaning motor to drive the rotation of the reciprocating dust suction roller, providing corresponding power for the rotation of the reciprocating dust suction roller, enabling the reciprocating dust suction roller to drive the reciprocating cleaning brushes to rotate, and enabling the reciprocating cleaning brushes to clean the pressing machine backing plate through rotation.

[0019] In one or more embodiments of the present invention, the suction cleaning mechanism includes a suction air pump capable of extracting the air inside the suction connecting hose, enabling the air inside the reciprocating dust suction drum to be extracted, so that the reciprocating dust suction drum can continuously suck the surface of the press platen through the dust suction holes, reducing the debris remaining on the surface of the press platen and improving the cleaning degree of the surface of the press platen, thereby improving the flatness of the surface of the press platen;

[0020] One end of the reciprocating dust suction drum away from the cleaning power shaft is fixedly installed with a suction hollow shaft, which connects the reciprocating dust suction drum and the suction connecting hose, enabling the suction connecting hose to extract the air inside the reciprocating dust suction drum, enabling the debris to be extracted by the suction air pump. At the same time, the suction hollow shaft can cooperate with the cleaning power shaft to fix the position of the reciprocating dust suction drum, reducing the probability of the reciprocating dust suction drum detaching, ensuring the balance of the reciprocating dust suction drum, and reducing the probability of the reciprocating dust suction drum tilting.

[0021] In one or more embodiments of the present invention, both the cleaning power shaft and the suction hollow shaft penetrate through the reciprocating cleaning support frame and the reciprocating dust suction drum, connecting the reciprocating dust suction drum, so that the air inside the reciprocating dust suction drum can be extracted by the suction connecting hose;

[0022] A number of evenly distributed dust suction holes are drilled on the reciprocating dust suction drum, which can clean the surface of the press platen, reducing the probability of debris remaining on the surface of the press platen and improving the flatness of the surface of the press platen.

[0023] In one or more embodiments of the present invention, a suction connecting hose is installed between the suction air pump and the suction hollow shaft, connecting the suction air pump and the suction hollow shaft, enabling the suction air pump to drive the air and discharge the air inside the reciprocating dust suction drum. The suction hollow shaft connects the reciprocating dust suction drum and the suction connecting hose.

[0024] In one or more embodiments of the present invention, the balance threaded rod penetrates through the circuit board press, capable of driving the displacement of the balance threaded block, making the sliding of the balance threaded block more controllable and the displacement of the balance threaded block smoother, reducing the probability of the reciprocating dust suction drum tilting;

[0034] In one or more embodiments of the present invention, the self-weight type cleaning mechanism includes a self-weight type scraper, which can move synchronously with the reciprocating dust suction drum when the reciprocating dust suction drum displaces, so that the debris adhered to the surface of the laminator backing plate can be scraped off, improving the flatness of the surface of the laminator backing plate. At the same time, when the self-weight type scraper slides back, the flatness of the laminator backing plate can be detected. When the self-weight type scraper drives the self-weight rotating shaft sleeve to rotate, it proves that the surface of the laminator backing plate is not flat;

[0057] As Figures 1 to 12 shown, a laminator backing plate 101 is fixedly installed on the upper side of the circuit board laminator 1. A reciprocating cleaning mechanism 2 is provided on one side of the laminator backing plate 101. The reciprocating cleaning mechanism 2 includes a reciprocating dust suction roller 201, which can drive the rotation of the reciprocating cleaning brush 202 through rotation, so that the reciprocating cleaning brush 202 can continuously clean the surface of the laminator backing plate 101, and the debris adhered to the surface of the laminator backing plate 101 is cleaned off, facilitating the suction of the suction holes.

[0058] Optionally, a pressure sensor can be fixedly installed on the lower side of the laminator backing plate 101. After the circuit board laminator 1 completes lamination and the pressure becomes smaller, the balancing motor 407 is started to rotate the balancing threaded rod 401, so that the reciprocating dust suction roller 201 can clean the laminator backing plate 101 automatically after each lamination.

[0059] Among them, a number of uniformly distributed reciprocating cleaning brushes 202 are fixedly installed outside the reciprocating dust suction roller 201, which can be driven by the reciprocating dust suction roller 201 to rotate and clean the surface of the laminator backing plate 101.

[0060] In addition, reciprocating cleaning support frames 203 are provided on both sides of the reciprocating dust suction roller 201, which can support the reciprocating dust suction roller 201, improve the stability of the reciprocating dust suction roller 201, reduce the probability of the reciprocating dust suction roller 201 tilting, and make the reciprocating cleaning brush 202 better fit the laminator backing plate 101.

[0061] In addition, a reciprocating cleaning motor 204 is fixedly installed on the reciprocating cleaning support frame 203, which can drive the rotation of the cleaning power shaft 206, provide corresponding power for the rotation of the cleaning power shaft 206, and make the rotation of the reciprocating dust suction roller 201 obtain corresponding power.

[0062] As Figures 1 to 5As shown, an electric telescopic rod 205 is fixedly installed on the lower side of the reciprocating cleaning support frame 203, which can control the lifting of the reciprocating cleaning support frame 203, adjust the position of the reciprocating cleaning support frame 203, ensure the balance of a pair of reciprocating cleaning support frames 203, reduce the probability of the reciprocating dust suction roller 201 tilting. At the same time, the reciprocating dust suction roller 201 can better adhere to the press platen 101, and the reciprocating cleaning fine brush 202 on the reciprocating dust suction roller 201 can better clean the press platen 101, reducing the probability of residual debris on the surface of the press platen 101.

[0063] Among them, a cleaning power shaft 206 is installed between the reciprocating cleaning motor 204 and the reciprocating dust suction roller 201, connecting the reciprocating cleaning motor 204 and the reciprocating dust suction roller 201, enabling the reciprocating dust suction roller 201 to be driven by the reciprocating cleaning motor 204, enabling the power of the reciprocating cleaning motor 204 to drive the rotation of the reciprocating dust suction roller 201, providing corresponding power for the rotation of the reciprocating dust suction roller 201, enabling the reciprocating dust suction roller 201 to drive the reciprocating cleaning fine brush 202 to rotate, and enabling the reciprocating cleaning fine brush 202 to clean the press platen 101 through rotation.

[0064] As Figures 1 to 5 shown, a suction-type cleaning mechanism 3 is fixedly installed on one side of the circuit board press 1. The suction-type cleaning mechanism 3 includes a suction air pump 301, which can extract the air in the suction connection hose 303, enabling the air in the reciprocating dust suction roller 201 to be extracted, enabling the reciprocating dust suction roller 201 to continuously suck the surface of the press platen 101 through the suction holes, reducing the residual debris on the surface of the press platen 101, improving the cleaning degree of the surface of the press platen 101, and further improving the flatness of the surface of the press platen 101.

[0065] In addition, a suction hollow shaft 302 is fixedly installed at one end of the reciprocating dust suction roller 201 far from the cleaning power shaft 206, connecting the reciprocating dust suction roller 201 and the suction connection hose 303, enabling the suction connection hose 303 to extract the air in the reciprocating dust suction roller 201, enabling the debris to be extracted by the suction air pump 301. At the same time, the suction hollow shaft 302 can cooperate with the cleaning power shaft 206 to fix the position of the reciprocating dust suction roller 201, reducing the probability of the reciprocating dust suction roller 201 detaching, ensuring the balance of the reciprocating dust suction roller 201, and reducing the probability of the reciprocating dust suction roller 201 tilting.

[0066] As Figures 1 to 4 shown, both the cleaning power shaft 206 and the suction hollow shaft 302 penetrate through the reciprocating cleaning support frame 203 and the reciprocating dust suction roller 201, connecting the reciprocating dust suction roller 201, enabling the air in the reciprocating dust suction roller 201 to be extracted by the suction connection hose 303.

[0067] In addition, a number of evenly distributed dust suction holes are drilled on the reciprocating dust suction roller 201, which can clean the surface of the pressing machine backing plate 101, reduce the probability of residual debris on the surface of the pressing machine backing plate 101, and improve the flatness of the surface of the pressing machine backing plate 101.

[0068] As Figures 1 to 4 shown, a suction connecting hose 303 is installed between the suction air pump 301 and the suction hollow shaft 302, connecting the suction air pump 301 and the suction hollow shaft 302, enabling the suction air pump 301 to drive air and discharge the air in the reciprocating dust suction roller 201. The suction hollow shaft 302 connects the reciprocating dust suction roller 201 and the suction connecting hose 303.

[0069] As Figures 1 to 6 shown, a balance reciprocating mechanism 4 is provided on the lower side of the reciprocating dust suction roller 201. The balance reciprocating mechanism 4 includes a balance threaded rod 401, which can drive the displacement of the balance threaded block 404 by rotation, enabling the reciprocating dust suction roller 201 to obtain synchronous displacement, so that the reciprocating dust suction roller 201 can clean the pressing machine backing plate 101 in a larger range.

[0070] In addition, a balance support rod 402 is provided on one side of the balance threaded rod 401, which can improve the balance of the balance sliding block 405, enabling the reciprocating dust suction roller 201 to be better controlled during the sliding process.

[0071] Furthermore, a balance force receiving pulley 403 is fixedly installed at one end of the balance threaded rod 401, which can be driven by the balance synchronous belt 409 to rotate, providing corresponding power for the rotation of the balance threaded rod 401.

[0072] As Figures 1 to 7 shown, the balance threaded rod 401 penetrates through the circuit board press 1, which can drive the displacement of the balance threaded block 404, making the sliding of the balance threaded block 404 more controllable and the displacement of the balance threaded block 404 smoother, reducing the probability of the reciprocating dust suction roller 201 tilting.

[0073] Among them, the balance support rod 402 is fixedly installed on the circuit board press 1, improving the balance of the balance support rod 402, reducing the probability of the balance support rod 402 tilting and the probability of the balance support rod 402 detaching, and enhancing the stability of the balance support rod 402.

[0074] In addition, a balance threaded block 404 is installed on the balance threaded rod 401, which can support the electric telescopic rod 205, ensuring the stability of the electric telescopic rod 205, reducing the probability of the electric telescopic rod 205 detaching, enabling the electric telescopic rod 205 to better support the reciprocating cleaning support frame 203, and making the reciprocating cleaning support frame 203 more controllable.

[0075] In addition, a balance sliding block 405 is slidably mounted on the balance support rod 402, which can cooperate with the balance threaded block 404 to slide the position of the reciprocating dust suction drum 201, reducing the probability of the reciprocating dust suction drum 201 tilting, improving the stability of the reciprocating dust suction drum 201, and ensuring the balance of the reciprocating dust suction drum 201.

[0076] Such as Figures 1 to 8 As shown, a balance sliding bearing 406 is installed between the balance support rod 402 and the balance sliding block 405, improving the smoothness of the sliding of the balance sliding block 405 and making the sliding of the balance sliding block 405 more controllable.

[0077] Among them, a pair of electric telescopic rods 205 are fixedly installed with the balance threaded block 404 and the balance sliding block 405 respectively, enabling the balance threaded block 404 and the balance sliding block 405 to support the electric telescopic rods 205 respectively, and ensuring the stability of the electric telescopic rods 205.

[0078] Such as Figures 1 to 8 As shown, a balance motor 407 is fixedly installed inside the circuit board laminator 1, which can drive the rotation of the balance force - applying pulley 408, providing corresponding power for the rotation of the balance force - applying pulley 408, improving the controllability of the balance force - applying pulley 408, and improving the stability of the balance force - applying pulley 408.

[0079] Among them, the balance motor 407 passes through the circuit board laminator 1, facilitating the connection between the balance motor 407 and the balance force - applying pulley 408 and facilitating the fixation of the position of the balance force - applying pulley 408.

[0080] In addition, a balance force - applying pulley 408 is fixedly installed on the balance motor 407, which can drive the rotation of the balance force - receiving pulley 403 through the balance synchronous belt 409, providing corresponding power for the rotation of the balance force - receiving pulley 403.

[0081] In addition, a balance synchronous belt 409 is installed between the balance force - applying pulley 408 and the balance force - receiving pulley 403, playing a role in transmission, enabling the balance force - applying pulley 408 to drive the rotation of the balance force - receiving pulley 403.

[0082] Such as Figures 1 to 10As shown, a self-weight type cleaning mechanism 5 is provided on one side of the reciprocating dust suction roller 201. The self-weight type cleaning mechanism 5 includes a self-weight type scraper 501, which can move synchronously with the reciprocating dust suction roller 201 when the reciprocating dust suction roller 201 moves, so that the debris adhered to the surface of the press platen 101 can be scraped off, improving the flatness of the surface of the press platen 101. At the same time, when the self-weight type scraper 501 slides back, the flatness of the press platen 101 can be detected. When the self-weight type scraper 501 drives the self-weight rotating shaft sleeve 502 to rotate, it proves that the surface of the press platen 101 is not flat.

[0083] Wherein, self-weight rotating shaft sleeves 502 are fixedly installed at both ends of the self-weight type scraper 501, which can fix the position of the self-weight type scraper 501, so that the self-weight type scraper 501 can rotate around the cleaning power shaft 206 and the suction hollow shaft 302, enabling the self-weight type scraper 501 to rotate naturally following its own gravity, and making the self-weight type scraper 501 always be able to fit with the surface of the press platen 101.

[0084] In addition, self-weight support blocks 503 are fixedly installed on the closer sides of a pair of reciprocating cleaning support frames 203, which can support the self-weight type scraper 501. When the self-weight type scraper 501 is not supported by the press platen 101, it can be supported by the self-weight support blocks 503, so that no matter where the self-weight type scraper 501 slides to, it can fit with the press platen 101 again and will not be stuck by both sides of the press platen 101.

[0085] As Figures 1 to 12 shown, the self-weight support blocks 503 match the self-weight type scraper 501. Rotation sensors 504 are fixedly installed on the closer sides of a pair of reciprocating cleaning support frames 203, which can detect the rotation of the self-weight rotating shaft sleeve 502. When the self-weight type scraper 501 slides back, it can detect whether the self-weight rotating shaft sleeve 502 rotates. By the rotation of the self-weight rotating shaft sleeve 502, it can be detected whether there is still residual debris on the surface of the press platen 101. The rotation sensors 504 are connected to the self-weight rotating shaft sleeves 502.

[0086] During actual use, after the circuit board laminator 1 finishes laminating, the user takes out the laminated circuit board, and the balancing motor 407, the suction air pump 301, and the reciprocating cleaning motor 204 are started. Through the rotation of the balancing motor 407 and the transmission of the balancing synchronous belt 409, the balancing screw rod 401 drives the balancing threaded block 404 to displace, and the balancing threaded block 404 drives the reciprocating dust suction roller 201 to perform synchronous displacement. During the displacement process, the reciprocating dust suction roller 201 rotates, and the surface of the laminator backing plate 101 is cleaned by the reciprocating cleaning fine brush 202. At this time, the debris swept down will enter the reciprocating dust suction roller 201 along with the air flow and be discharged by the suction air pump 301. When the self-weight type scraper 501 is cleaning, it will first pass over the surface of the laminator backing plate 101 to scrape off the stubbornly adhered debris. While improving the cleaning effect of the reciprocating cleaning fine brush 202, it can also improve the surface flatness of the laminator backing plate 101. When the reciprocating dust suction roller 201 slides back, it can clean the surface of the laminator backing plate 101 again. The self-weight type scraper 501 can rotate when it encounters debris through contact with the laminator backing plate 101. The rotation is detected by the rotation sensor 504, and it can be determined whether the surface of the laminator backing plate 101 is clean, reducing the production cost of the circuit board.

[0087] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
