Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically to a multilayer PCB board laminating equipment. Background Technology

[0002] A PCB, or Printed Circuit Board, is a crucial component of the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, 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, serving the dual purpose of conducting circuitry and providing insulation. It replaces complex wiring, enabling electrical connections between components in a circuit. This simplifies assembly and soldering, reduces the amount of wiring work required in traditional methods, significantly lessening the workload for workers; it also reduces overall size, lowers product costs, and improves the quality and reliability of electronic equipment.

[0003] A PCB board laminating device with existing patent application number 202220595457.1 has a cleaning mechanism that uses contact cleaning. During cleaning, the outer side of the cleaning rod contacts the substrate, but the dust remains on the surface of the cleaning rod and is not removed. When the device is reused, or when it rotates, the dust adhering to the surface of the cleaning rod will come into contact with the substrate again, resulting in poor cleaning effect. Therefore, a multilayer PCB board laminating device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a multilayer PCB board laminating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multilayer PCB board laminating device, comprising a laminating device, a laminating plate, and a placement plate;

[0006] The pressing equipment is also equipped with a pressing plate for pressing PCB boards.

[0007] The pressing equipment is equipped with a placement plate for placing PCB boards.

[0008] The side of the pressing equipment is equipped with a dust removal mechanism for cleaning PCB boards, and one end of the dust removal mechanism is fixedly connected to an extrusion mechanism distributed in the front and back.

[0009] The dust removal mechanism includes a mounting frame, a movable component, an air pump, an air pipe, and exhaust nozzles. The outer side of the mounting frame is fixedly connected to the pressing equipment. An air pump is installed inside the upper part of the mounting frame. The output end of the air pump is connected to an air pipe, and the other end of the air pipe is connected to multiple exhaust nozzles arranged longitudinally. The outer side of the exhaust nozzles is fixedly connected to the movable component. One side of the movable component is fixedly connected to the mounting frame, and the other end of the movable component is fixedly connected to the pressing mechanism.

[0010] Existing technology products have cleaning mechanisms that employ contact cleaning. During cleaning, the outer side of the cleaning rod contacts the substrate, but the dust remains on the surface of the cleaning rod and is not removed. When reused, or when the device rotates, the dust adhering to the surface of the cleaning rod is brought back into contact with the substrate, resulting in poor cleaning effectiveness. In contrast, this device, since the substrate surface often has a small amount of light dust, moves the exhaust nozzle via a moving component, and the air pump starts to expel external air through the air pipe and exhaust nozzle. This allows for non-contact cleaning of the substrate surface, ensuring cleaning quality.

[0011] Furthermore, the moving part includes a motor, a threaded shaft, and a threaded hole plate. The outer side of the motor is fixedly connected to the mounting frame. The end of the motor's main shaft is fixedly connected to the threaded shaft. The outer side of the threaded shaft is spirally connected to the threaded hole plate, and the other end of the threaded hole plate is fixedly connected to a pressing mechanism distributed in a front-to-back manner.

[0012] Furthermore, the bottom of the threaded hole plate is provided with a sliding groove, and the threaded hole plate is slidably connected to a guide block through the sliding groove, and the other end of the guide block is fixedly connected to the mounting frame.

[0013] The threaded shaft is driven to rotate by the motor, which in turn drives the threaded hole plate to move. At this time, the extrusion mechanism on one side will move and extrude the base plate to fix the base plate. Meanwhile, the guide block is set to guide the threaded hole plate to ensure its stable movement.

[0014] Furthermore, a fixing plate is fixedly connected to the outside of the trachea, and a first spring is fixedly connected to one side of the fixing plate, while the other side of the first spring is fixedly connected to the mounting frame.

[0015] Furthermore, a guide frame is provided on the outside of the air tube, and a guide roller is rotatably connected to the outside of the guide frame. The outside of the guide roller is fixedly connected to the mounting frame.

[0016] When the threaded sleeve moves, its air tube will move along with it. The first spring and the fixed plate ensure that the air tube is reset when the threaded sleeve is reset, thus avoiding the air tube from becoming messy. The guide frame can guide the air tube.

[0017] Furthermore, the extrusion mechanism includes a fixed frame, an extrusion wheel, and a fixed plate. The extrusion wheel is installed at the bottom of the fixed frame, a sliding plate is slidably connected inside the fixed frame, and a fixed plate is fixedly connected to the top of the sliding plate. The top of the fixed plate is fixedly connected to the dust removal mechanism.

[0018] Furthermore, a second spring is fixedly connected to the bottom of the sliding plate, and the bottom of the second spring is fixedly connected to the fixing frame.

[0019] During cleaning, the extrusion rollers on both sides will contact the substrate to fix it. The second spring ensures that the extrusion rollers have a certain buffering performance, ensuring that the extrusion is fixed for substrates of different thicknesses, thus ensuring the cleaning quality and the subsequent pressing quality.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] When this utility model is in use, since the substrate surface is often covered with a small amount of dust and is relatively light, the moving part drives the exhaust nozzle to move, and the air pump starts to drive the external air to be discharged through the air pipe and exhaust nozzle. At this time, the substrate surface can be cleaned without contact, ensuring the cleaning quality.

[0022] During cleaning, the extrusion rollers on both sides will contact the substrate to fix it. The springs ensure that the extrusion rollers have a certain buffering performance, ensuring that the extrusion is fixed for substrates of different thicknesses, thus ensuring the cleaning quality and the subsequent pressing quality.

[0023] When the threaded orifice plate moves, its air tube will move along with it. The first spring and the fixed plate ensure that the air tube is reset when the threaded orifice plate is reset, thus avoiding the air tube from becoming messy. The guide frame can guide the air tube. Attached Figure Description

[0029] 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.

[0030] Example 1: Please refer to Figure 1 and Figure 2 This utility model provides a technical solution:

[0031] A multilayer PCB board laminating device includes a laminating device 1, a laminating plate 2, and a placement plate 3;

[0032] The aforementioned pressing equipment 1 also contains a pressing plate 2 for pressing PCB boards;

[0033] The aforementioned pressing equipment 1 has a placement plate 3 for placing PCB boards installed inside;

[0034] The side of the pressing equipment 1 is equipped with a dust removal mechanism 4 for cleaning PCB boards, and one end of the dust removal mechanism 4 is fixedly connected to an extrusion mechanism 5 distributed in the front and back.

[0035] The dust removal mechanism 4 includes a mounting frame 401, a movable component, an air pump 405, an air pipe 406, and an exhaust nozzle 407. The outer side of the mounting frame 401 is fixedly connected to the pressing device 1. The air pump 405 is installed inside the upper part of the mounting frame 401. The output end of the air pump 405 is connected to the air pipe 406, and the other end of the air pipe 406 is connected to a plurality of exhaust nozzles 407 arranged longitudinally. The outer side of the exhaust nozzle 407 is fixedly connected to the movable component. One side of the movable component is fixedly connected to the mounting frame 401, and the other end of the movable component is fixedly connected to the pressing mechanism 5.

[0036] Existing technology products have cleaning mechanisms that use contact cleaning. During cleaning, the outer side of the cleaning rod contacts the substrate, but the dust remains on the surface of the cleaning rod and is not removed. When reused, or when the device rotates, the dust adhering to the surface of the cleaning rod will come into contact with the substrate again, resulting in poor cleaning effect. In contrast, when this device is used, since the substrate surface often has a small amount of dust adhering to it and the dust is relatively light, the moving part drives the exhaust nozzle 407 to move, and the air pump 405 starts to drive the external air to be discharged through the air pipe 406 and the exhaust nozzle 407. At this time, the substrate surface can be cleaned without contact, ensuring cleaning quality.

[0037] In this embodiment, the exhaust nozzle 407 is inclined, which facilitates pushing impurities on the substrate surface to one side to achieve contactless cleaning, resulting in better cleaning effect compared to the prior art.

[0038] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 Specifically, the aforementioned moving parts include a motor 402, a threaded shaft 403, and a threaded hole plate 404. The outer side of the motor 402 is fixedly connected to the mounting frame 401. The end of the main shaft of the motor 402 is fixedly connected to the threaded shaft 403. The outer side of the threaded shaft 403 is spirally connected to the threaded hole plate 404, and the other end of the threaded hole plate 404 is fixedly connected to a pressing mechanism 5 distributed in a front-to-back manner.

[0039] The bottom of the threaded hole plate 404 is provided with a sliding groove, and the threaded hole plate 404 is slidably connected to the guide block 412 through the sliding groove, and the other end of the guide block 412 is fixedly connected to the mounting frame 401.

[0040] The motor 402 drives the threaded shaft 403 to rotate, thereby driving the threaded hole plate 404 to move. At this time, the pressing mechanism 5 on one side will move and press the substrate to fix the substrate. Meanwhile, the guide block 412 is set to guide the threaded hole plate 404 to ensure its stable movement.

[0041] In this embodiment, the threaded plate 404 is arranged in a rectangular frame, which facilitates the installation of two sets of extrusion mechanisms 5 at the bottom for fixing the two sides of the substrate.

[0042] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 3 Specifically, a fixing plate 409 is fixedly connected to the outside of the aforementioned trachea 406, and a first spring 408 is fixedly connected to one side of the fixing plate 409. The other side of the first spring 408 is fixedly connected to the mounting frame 401.

[0043] A guide frame 410 is also provided on the outside of the aforementioned air pipe 406, and a guide roller 411 is rotatably connected to the outside of the guide frame 410. The outside of the guide roller 411 is fixedly connected to the mounting frame 401.

[0044] When the threaded sleeve 404 moves, its air tube 406 will move accordingly. The first spring 408 and the fixed plate 409 ensure that the air tube 406 is reset when the threaded sleeve 404 is reset, thus preventing the air tube 406 from becoming messy. The guide frame 410 can guide the air tube 406 to prevent it from being damaged by long-term friction.

[0045] Example 4: This example is an improvement on Example 3. Please refer to [link / reference]. Figure 4 Specifically, the extrusion mechanism 5 includes a fixed frame 501, an extrusion wheel 502, and a fixed plate 503. The extrusion wheel 502 is installed at the bottom of the fixed frame 501. A sliding plate 504 is slidably connected inside the fixed frame 501, and a fixed plate 503 is fixedly connected to the top of the sliding plate 504. The top of the fixed plate 503 is fixedly connected to the dust removal mechanism 4.

[0046] The bottom of the sliding plate 504 is fixedly connected to a second spring 505, and the bottom of the second spring 505 is fixedly connected to the fixing frame 501.

[0047] During cleaning, the extrusion rollers 502 on both sides will contact the substrate to fix it. The extrusion rollers 502 will also drive the fixing frame 501 to move upward. Under the combined action of the fixing frame 501 and the sliding plate 504, the second spring 505 is compressed. The second spring 505 can ensure that the extrusion rollers 502 have a certain buffering performance, ensuring that the extrusion fixing is performed on substrates of different thicknesses, ensuring the cleaning quality and the subsequent pressing quality.
