Description

Technical Field

[0001] The invention relates to the technical field of copper clad plate processing, in particular to a CCL plate press forming device with a real-time monitoring function. Background Art

[0002] Copper clad laminate (CCL), a fundamental material in the electronics industry, is widely used in the manufacture of printed circuit boards (PCBs). Its quality directly impacts the performance and reliability of PCBs, and thus the overall quality of various electronic devices. During the press-forming process of CCL boards, precise control of surface flatness and thickness, as well as effective application of edge glue, are crucial.

[0003] However, the traditional CCL board press forming process faces numerous challenges in these areas. First, in terms of surface flatness control, existing testing methods often rely on offline sampling. This involves sampling a portion of a batch of CCL boards after they are formed for flatness measurement. This method cannot monitor each CCL board in real time during the press forming process, making it difficult to promptly detect flatness issues caused by factors such as uneven pressure, mold deformation, or material differences.

[0004] The existing methods for measuring the thickness of copper clad laminates mainly include mechanical contact measurement and ultrasonic measurement. Mechanical contact measurement, such as using a caliper or thickness gauge, is relatively simple to operate, but it can easily scratch the surface of the copper clad laminate, and the measurement accuracy is limited. The detection sensitivity for small changes in thickness is insufficient, and it is difficult to meet the higher requirements for thickness accuracy control in modern CCL board production. Although ultrasonic measurement is non-contact measurement, when there are pores inside the copper clad laminate or the interface between different material layers is unclear, it will lead to large measurement errors. Most detection equipment can only perform offline detection after the copper clad laminate is pressed together. It is impossible to detect thickness deviations and make adjustments in time during the pressing process. As a result, once a thickness problem occurs, the entire batch of copper clad laminates may need to be scrapped or reworked, increasing production costs and production cycles.

[0005] Most of the existing edge glue processing technologies are independent of the subsequent processes of the copper clad laminate lamination process, and lack effective linkage and integration with the lamination process. This results in the need for secondary handling and positioning of the copper clad laminate during the edge glue processing process, which increases the complexity of the production process and the possibility of errors, while also reducing production efficiency. Summary of the Invention

[0006] The object of the present invention is to provide a CCL board press forming device with real-time monitoring function to solve the problems raised in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The CCL board press forming device with real-time monitoring function includes a work box, a flatness detection unit, a thickness detection unit, a glue removal unit and a control console. The work box is placed on an external machine platform. A guide slide is provided in the work box. A first electrode plate is provided at one end of the guide slide away from the horizontal ground. The flatness detection unit is fixedly installed inside the work box. The thickness detection unit is fixedly installed inside the work box. The glue removal unit is slidably installed in the guide slide. The flatness detection unit is electrically connected to the thickness detection unit. The glue removal unit has the function of removing glue from the edge of the plate. The glue removal unit is electrically connected to the flatness detection unit. The control console is fixedly installed on the outer surface of the work box.

[0009] The working box is used to install and fix the flatness detection unit, thickness detection unit, glue removal unit and control console. The flatness detection unit is used to detect the flatness of the plate surface online. The thickness detection unit is used to detect online whether the thickness of the formed plate meets the production standard. The glue removal unit is used to remove the glue on the edge of the plate when the plate is pressed and formed. The control console is used to control the start and stop of the device. When the plate to be pressed is placed on the glue removal unit for pressing, the glue removal unit is used to scrape off the edge glue overflowed during the plate pressing process. At the same time, the flatness detection unit and the thickness detection unit are used to detect the thickness or surface flatness of the plate during the pressing process online, which facilitates timely adjustment, reduces the scrap rate of the copper clad laminate, and improves production quality.

[0010] Furthermore, the flatness detection unit includes a telescopic motor, a magnet, a heating plate, a flat plate and a right-angle push rod. The fixed end of the telescopic motor is fixedly installed on the outer surface of the working box away from the horizontal ground. The telescopic end of the telescopic motor is fixedly connected to the magnet. The heating plate is fixedly installed on the surface of the magnet close to the horizontal ground. The flat plate is fixedly installed on the outer surface of the heating plate. One end of the right-angle push rod is fixedly connected to the heating plate, and the other end is provided with a circular top block. The first electrode plate is electrically connected to the telescopic motor.

[0011] Furthermore, the flatness detection unit also includes a fixed box, a straight cylinder, a push block, a telescopic spring, a guide block, a conductive plate, a laser transmitter, a receiver and a rectangular coil. The fixed box is fixedly mounted on the inner wall of the working box, and a circular groove for mounting the straight cylinder is provided at one end of the fixed box close to the right-angle push rod. The straight cylinder is fixedly mounted inside the fixed box, and one end of the straight cylinder and the right-angle push rod are parallel to the vertical axis and on the same axis. An arc-shaped notch is provided at the bottom of the straight cylinder, and one end of the push block is slidably mounted in the arc-shaped notch of the straight cylinder, and the other end is connected to the guide block through a telescopic spring. The push block is provided with a flexible conductive block near one end of the guide block. The push block is a trapezoidal structure, and the push-open inclined portion at one end of the straight cylinder is a trapezoidal shape. The conductive plate is fixedly installed inside the guide block, and the conductive plate is electrically connected to the thickness detection unit. The guide block is fixedly installed on the inner wall of the fixed box, the laser transmitter is fixedly installed on the inner wall of the working box away from the fixed box, the receiver is fixedly installed inside the fixed box, the rectangular coil is evenly wound inside the working box, the rectangular coil is electrically connected to the glue removal unit, and the laser transmitter is electrically connected to the conductive plate.

[0012] When the copper clad laminate needs to be pressed, the control console controls the telescopic motor to start, thereby driving the magnet and the heated pressing plate to move downward synchronously, on the one hand driving the flat plate and the right-angle push rod to move downward, until the right-angle push rod moves downward, contacts the push block and squeezes the push block to move to the right to compress the telescopic spring, thereby driving the flexible conductive block on the push block to contact the conductive plate, so that part of the current of the control console is transmitted to the coil on the arc rod through the conductive plate, and the other part of the current is transmitted to the laser transmitter, thereby starting the laser transmitter, at this time the right-angle push rod continues to move downward to the bottom of the straight cylinder driven by the telescopic motor and stops moving. At this time, the control console controls The heating platen heats the copper clad laminate, thereby realizing the pressing and forming of the copper clad laminate. When the copper clad laminate is pressed, the console controls the telescopic motor to contract, driving the right-angle push rod to extend from the straight cylinder, and the push block is pushed to the left and reset under the action of the restoring force of the telescopic spring. When the heating platen leaves the surface of the copper clad laminate, the laser transmitter emits a laser, and the receiver receives the signal and converts it into an electrical signal to the console, thereby realizing online detection of the flatness of the copper clad laminate surface. On the other hand, when the magnet moves downward in the rectangular coil, the magnetic flux changes, thereby generating a positive current in the rectangular coil and transmitting it to the electromagnet, so that the electromagnet is energized and produces polarity.

[0013] Furthermore, the thickness detection unit includes a mounting frame, a support plate, a straight rod, a rocker arm and an arc rod. The mounting frame is fixedly mounted on the inner wall of the working box, the support plate is vertically fixedly mounted on the surface of the mounting frame at one end away from the working box, there are two support plates, and the two support plates are fixedly connected by a straight rod, one end of the rocker arm is rotatably connected to the straight rod, and the other end is slidably connected to the arc rod, a rectangular groove for the rocker arm to rotate is provided on the mounting frame, both ends of the arc rod are fixedly mounted on the upper and lower inner walls of the mounting frame, a coil is evenly wound on the surface of the arc rod, a conductive ring iron is provided at the contact end between the rocker arm and the arc rod, the rocker arm is electrically connected to the control console, and the coil provided on the arc rod is electrically connected to the conductive plate.

[0014] When the telescopic motor drives the plate to move downward until the heating plate is in full contact with the copper-clad laminate, the plate pushes the pendulum rod to rotate downward around the straight rod, and the other end rotates upward along the arc rod. The current is transmitted to the coil on the arc rod through the conductive plate. When the conductive ring iron on the pendulum rod contacts the coil, the effective number of turns of the coil changes, and the resistance value changes synchronously, thereby causing the current value transmitted to the control console by the pendulum rod to change. The control console detects whether the current change value at this time exceeds the preset range. If it exceeds, the control console adjusts the distance the heating plate is lowered, so that the copper-clad laminate with thickness deviation can be adjusted in time during the pressing process, thereby reducing the scrap rate and improving production quality.

[0015] Furthermore, the glue removal unit includes a driving motor, a lifting plate, a limit platform, a buffer spring, a limit rod, a second electrode plate, an electromagnet, a magnetic block, a scraper and a multi-stage telescopic rod. The output end of the driving motor is fixedly mounted on the surface of the lifting plate close to the horizontal ground, the limit platform is fixedly mounted on the surface of the lifting plate away from the horizontal ground, the buffer spring is fixedly mounted on the surface of the lifting plate away from the horizontal ground, one end of the limit rod is fixedly connected to the lifting plate, and the other end is slidably mounted inside the guide slide groove, and the end of the limit rod away from the horizontal ground is fixedly mounted with the second electrode plate, the electromagnet is fixedly mounted on the inner wall of the fixed end of the multi-stage telescopic rod, the magnetic block is fixedly mounted on the inner wall of the telescopic end of the multi-stage telescopic rod, the electromagnet is electrically connected to the rectangular coil, the scraper is vertically fixedly connected to the telescopic end of the multi-stage telescopic rod through a connecting rod, and the end of the scraper close to the horizontal ground is slidably connected to the lifting plate through a long rod.

[0016] When the copper clad laminate to be processed is placed on the limit table, the drive motor is started by controlling the control console, which drives the lifting plate to move upward, thereby driving the copper clad laminate on the limit table to move synchronously to the height to be pressed, and then stops moving. At this time, the limit rod moves upward along the inside of the guide slide until the second electrode plate contacts the first electrode plate. At this time, the current is transmitted to the telescopic motor through the second electrode plate and the first electrode plate, thereby controlling the heating press plate to move downward, contact with the buffer spring and slowly compress, so that the pressure of the heating press plate on the copper clad laminate is more uniform, thereby ensuring that the resin in various parts of the copper clad laminate can fully flow and solidify, improving the overall flatness and quality consistency of the copper clad laminate, and reducing thickness deviation and delamination caused by uneven pressure. On the other hand, when the magnet moves downward, the current generated in the rectangular coil is transmitted to the electromagnet, and the electromagnet presents a polarity opposite to that of the magnetic block, thereby attracting the magnetic block to drive the scraper toward the electromagnet while contracting the multi-stage telescopic rod, thereby scraping off the board edge glue generated during the copper clad laminate pressing process, avoiding affecting the subsequent process, thereby improving the quality of the product; when the magnet moves upward under the action of the telescopic motor, the magnetic flux changes again, thereby generating a reverse current in the rectangular coil and transmitting it to the electromagnet, so that the electromagnet presents the same polarity as the magnetic block, thereby pushing the magnetic block to drive the scraper away from the electromagnet, and performing a secondary scraping of the board edge glue, thereby improving the cleaning effect of the board edge glue.

[0017] Furthermore, in the vertical direction, when the right-angle push rod moves to the middle of the push block, the push block contacts the conductive plate.

[0018] In order to ensure that the flexible conductive block on the push block keeps in contact with the conductive plate for a period of time during the upward return movement of the right-angle push rod, the heated platen no longer blocks the laser transmitter, allowing the receiver to receive the signal and transmit it to the control console for online detection and analysis of the flatness, thus eliminating the need for subsequent manual secondary inspections, saving manpower and improving work efficiency.

[0019] Furthermore, the length ratio of the swing rod close to one end of the straight rod and the swing rod away from one end of the straight rod is 1:8.

[0020] In order to improve the online thickness detection accuracy of the copper clad laminate during the pressing and forming process, the length ratio of the pendulum rod at both ends of the straight rod is used to compare and amplify the surface height of the copper clad laminate with the preset standard height, so that the device can more keenly capture subtle changes in the thickness of the copper clad laminate, which can greatly improve the detection resolution and thus more accurately detect the thickness.

[0021] Furthermore, the laser transmitter and the receiver are coaxially arranged.

[0022] In order to ensure that the laser emitted by the laser transmitter is accurately received by the receiver and fed back to the control console for analysis, real-time online detection of the flatness of the copper clad laminate during the pressing process can be achieved, which facilitates the timely detection of waste products, reduces the time for subsequent manual inspection, and improves work efficiency.

[0023] Furthermore, the heating platen is electrically connected to the control console, and the heating platen is composed of multiple groups of independent heating blocks, each of which is provided with multiple groups of temperature sensors.

[0024] In order to realize the automated production and processing of the device and save human resources, multiple groups of hot pressing blocks control the temperature of the copper clad laminate surface in different zones, accurately control the temperature and keep it synchronized, avoid the warping of the copper clad laminate caused by uneven surface temperature, reduce the scrap rate and improve production quality.

[0025] Furthermore, the console is provided with a monitoring screen and a start / stop button.

[0026] In order to facilitate workers to observe the processing process in real time, when the device encounters a fault, workers will be notified in time to stop the operation of the device, and it will be convenient for workers to replace the copper clad laminate.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, during the downward movement of the right-angle push rod, it contacts the push block and squeezes the push block to move to the right to compress the telescopic spring, thereby driving the flexible conductive block on the push block to contact the conductive plate, so that part of the current of the console is transmitted to the coil on the arc rod through the conductive plate, and the other part of the current is transmitted to the laser transmitter, thereby starting the laser transmitter. At this time, the right-angle push rod continues to move downward to the bottom of the straight cylinder driven by the telescopic motor and then stops moving. At this time, the console controls the heating press plate to heat the copper clad laminate, thereby realizing the pressing and forming of the copper clad laminate. When the pressing of the copper clad laminate is completed, the heating press plate leaves the surface of the copper clad laminate, the laser transmitter emits a laser, the receiver receives the signal and converts it into an electrical signal to the console, thereby realizing online detection of the flatness of the copper clad laminate surface. On the other hand, during the downward movement of the magnet in the rectangular coil, a positive current is generated in the rectangular coil and transmitted to the electromagnet, so that the electromagnet is energized and generates polarity.

[0029] 2. The present invention pushes the pendulum rod to rotate downward around the straight rod by moving the flat plate downward, and the other end rotates upward along the arc rod. The current is transmitted to the coil on the arc rod through the conductive plate. During the contact process between the conductive ring iron on the pendulum rod and the coil, the effective number of turns of the coil changes, and the resistance value changes synchronously, thereby causing the current value transmitted to the control console by the pendulum rod to change. The control console detects whether the current change value at this time exceeds a preset range. If it exceeds, the control console adjusts the distance that the heating press plate descends, thereby realizing timely adjustment of the copper clad laminate with thickness deviation during the pressing process, reducing the scrap rate and improving production quality.

[0030] 3. The present invention starts the driving motor to drive the limit rod to move upward along the inside of the guide slide until the second electrode plate contacts the first electrode plate. At this time, the current is transmitted to the telescopic motor through the second electrode plate and the first electrode plate, thereby controlling the heating press plate to move downward to pressurize the copper clad plate to be processed. On the other hand, during the downward movement of the magnet, the current generated in the rectangular coil is transmitted to the electromagnet, and the electromagnet changes its polarity, thereby controlling the magnetic block to drive the scraper to move, thereby scraping off the board edge glue generated during the pressing process of the copper clad plate to avoid affecting the subsequent process, thereby improving the quality of the product. When the magnet moves upward under the action of the telescopic motor, the magnetic flux changes again, thereby generating a reverse current in the rectangular coil and transmitting it to the electromagnet, so that the electromagnet presents the same polarity as the magnetic block, thereby pushing the magnetic block to drive the scraper away from the electromagnet, and performing a secondary scraping of the board edge glue, thereby improving the cleaning effect of the board edge glue.

[0031] 4. In order to improve the online thickness detection accuracy of the copper clad laminate during the pressing and forming process, the present invention compares and amplifies the surface height of the copper clad laminate with the preset standard height through the length ratio of the pendulum rod at both ends of the straight rod, so that the device can more keenly capture subtle changes in the thickness of the copper clad laminate, which can greatly improve the detection resolution and thus more accurately detect the thickness.

[0045] Example: Figures 1-11 As shown, the present invention provides a technical solution:

[0046] like Figure 1 、 2 As shown, a CCL board press forming device with real-time monitoring function includes a work box 1, a flatness detection unit 2, a thickness detection unit 3, a degumming unit 4 and a control console 5.

At the same time, the flatness detection unit 2 and the thickness detection unit 3 are used to detect the thickness or surface flatness of the plate during the pressing process online, which is convenient for timely adjustment, reducing the scrap rate of the copper clad laminate, and improving production quality.

[0048] like Figure 3 As shown, the flatness detection unit 2 includes a telescopic motor 21, a magnet 22, a heating plate 23, a flat plate 24 and a right-angle push rod 25. The fixed end of the telescopic motor 21 is fixedly mounted on the outer surface of the end of the working box 1 away from the horizontal ground, the telescopic end of the telescopic motor 21 is fixedly connected to the magnet 22, the heating plate 23 is fixedly mounted on the surface of the end of the magnet 22 close to the horizontal ground, the flat plate 24 is fixedly mounted on the outer surface of the heating plate 23, one end of the right-angle push rod 25 is fixedly connected to the heating plate 23, and the other end is provided with a circular top block, and the first electrode plate 12 is electrically connected to the telescopic motor 21.

[0049] like Figure 4 As shown, the flatness detection unit 2 also includes a fixed box 26, a straight cylinder 27, a push block 28, a telescopic spring 29, a guide block 210, a conductive plate 211, a laser transmitter 212, a receiver 213 and a rectangular coil 214. The fixed box 26 is fixedly mounted on the inner wall of the working box 1. A circular groove for mounting the straight cylinder 27 is provided at one end of the fixed box 26 close to the right-angle push rod 25. The straight cylinder 27 is fixedly mounted inside the fixed box 26. One end of the straight cylinder 27 and the right-angle push rod 25 are parallel to the vertical axis and are on the same axis. An arc-shaped notch is provided at the bottom of the straight cylinder 27. One end of the push block 28 is slidably mounted in the arc-shaped notch of the straight cylinder 27.

The guide block 210 is fixedly installed on the inner wall of the fixed box 26. The laser emitter 212 is fixedly installed on the inner wall of the working box 1 away from the fixed box 26. The receiver 213 is fixedly installed inside the fixed box 26. The rectangular coil 214 is evenly wound inside the working box 1. The rectangular coil 214 is electrically connected to the glue removal unit 4. The laser emitter 212 is electrically connected to the conductive plate 211.

[0050] When the copper clad laminate needs to be pressed, the telescopic motor 21 is started by controlling the console 5, thereby driving the magnet 22 and the heating plate 23 to move downward synchronously, and on the one hand, driving the flat plate 24 and the right-angle push rod 25 to move downward, until the right-angle push rod 25 moves downward, contacts the push block 28 and squeezes the push block 28 to move right to compress the telescopic spring 29, thereby driving the flexible conductive block on the push block 28 to contact the conductive plate 211, so that part of the current of the console 5 is transmitted to the coil on the arc rod 35 through the conductive plate 211, and the other part of the current is transmitted to the laser emitter 212, so that the laser emitter 212 is started. At this time, the right-angle push rod 25 continues to move downward to the bottom of the straight cylinder 27 under the drive of the telescopic motor 21 and stops moving. The console 5 controls the heating plate 23 to heat the copper clad laminate, thereby realizing the pressing and forming of the copper clad laminate. When the copper clad laminate is pressed, the console 5 controls the telescopic motor 21 to contract, driving the right-angle push rod 25 to extend from the straight cylinder 27, and the push block 28 is pushed to the left and reset under the action of the restoring force of the telescopic spring 29 itself. When the heating plate 23 leaves the surface of the copper clad laminate, the laser emitter 212 emits a laser, and the receiver 213 receives the signal and converts it into an electrical signal to the console 5, thereby realizing online detection of the flatness of the copper clad laminate surface. On the other hand, when the magnet 22 moves downward in the rectangular coil 214, the magnetic flux changes, thereby generating a positive current in the rectangular coil 214 and transmitting it to the electromagnet 47, so that the electromagnet 47 is energized and generates polarity.

[0051] like Figure 7 As shown, the thickness detection unit 3 includes a mounting frame 31, a support plate 32, a straight rod 33, a rocker arm 34 and an arc rod 35. The mounting frame 31 is fixedly mounted on the inner wall of the working box 1, and the support plate 32 is vertically fixedly mounted on the surface of the mounting frame 31 at one end away from the working box 1. There are two support plates 32, and the two support plates 32 are fixedly connected by the straight rod 33. One end of the rocker arm 34 is rotatably connected to the straight rod 33, and the other end is slidably connected to the arc rod 35. A rectangular groove for the rocker arm 34 to rotate is provided on the mounting frame 31. Both ends of the arc rod 35 are fixedly mounted on the upper and lower inner walls of the mounting frame 31. A coil is evenly wound on the surface of the arc rod 35. A conductive ring iron is provided at the contact end between the rocker arm 34 and the arc rod 35. The rocker arm 34 is electrically connected to the console 5, and the coil provided on the arc rod 35 is electrically connected to the conductive plate 211.

[0052] When the telescopic motor 21 drives the flat plate 24 to move downward until the heating plate 23 is in full contact with the copper clad laminate, the flat plate 24 pushes the pendulum rod 34 to rotate downward around the straight rod 33, and the other end rotates upward along the arc rod 35. The current is transmitted to the coil on the arc rod 35 through the conductive plate 211. When the conductive ring iron on the pendulum rod 34 is in contact with the coil, the effective number of turns of the coil changes, and the resistance value changes synchronously, thereby causing the current value transmitted to the console 5 by the pendulum rod 34 to change. The console 5 detects whether the current change value at this time exceeds the preset range. If it exceeds, the console 5 adjusts the distance the heating plate 23 descends, thereby realizing timely adjustment of the copper clad laminate with thickness deviation during the pressing process, reducing the scrap rate and improving production quality.

[0053] like Figure 5 、 8 As shown in FIG9 , 9 , 10 and 11 , the glue removal unit 4 includes a driving motor 41, a lifting plate 42, a limiting platform 43, a buffer spring 44, a limiting rod 45, a second electrode plate 46, an electromagnet 47, a magnetic block 48, a scraper 49 and a multi-stage telescopic rod 410. The output end of the driving motor 41 is fixedly mounted on the surface of one end of the lifting plate 42 close to the horizontal ground, the limiting platform 43 is fixedly mounted on the surface of the one end of the lifting plate 42 away from the horizontal ground, the buffer spring 44 is fixedly mounted on the surface of the one end of the lifting plate 42 away from the horizontal ground, and one end of the limiting rod 45 is fixedly mounted on the surface of the one end of the lifting plate 42 away from the horizontal ground. The lifting plate 42 is fixedly connected, and the other end is slidably installed inside the guide slide 11. The end of the limit rod 45 away from the horizontal ground is fixedly installed with a second electrode plate 46, the electromagnet 47 is fixedly installed on the inner wall of the fixed end of the multi-stage telescopic rod 410, and the magnetic block 48 is fixedly installed on the inner wall of the telescopic end of the multi-stage telescopic rod 410. The electromagnet 47 is electrically connected to the rectangular coil 214, and the scraper 49 is vertically fixedly connected to the telescopic end of the multi-stage telescopic rod 410 through a connecting rod. The scraper 49 is slidably connected to the lifting plate 42 through a long rod at the end close to the horizontal ground.

[0054] When the copper clad laminate to be processed is placed on the limit table 43, the drive motor 41 is started by controlling the control console 5, which drives the lifting plate 42 to move upward, thereby driving the copper clad laminate on the limit table 43 to move synchronously to the height to be pressed, and then stops moving. At this time, the limit rod 45 moves upward along the inside of the guide slide 11 until the second electrode plate 46 contacts the first electrode plate 12. At this time, the current is transmitted to the telescopic motor 21 through the second electrode plate 46 and the first electrode plate 12, thereby controlling the heating press plate 23 to move downward, contact with the buffer spring 44 and slowly compress, so that the pressure of the heating press plate 23 on the copper clad laminate is more uniform, thereby ensuring that the resin in various parts of the copper clad laminate can fully flow and solidify, improving the overall flatness and quality consistency of the copper clad laminate, and reducing defects such as thickness deviation and delamination caused by uneven pressure. On the one hand, during the downward movement of the magnet 22, the current generated in the rectangular coil 214 is transmitted to the electromagnet 47, and the electromagnet 47 presents a polarity opposite to that of the magnetic block 48, thereby attracting the magnetic block 48 to drive the scraper 49 toward the electromagnet 47 while contracting the multi-stage telescopic rod 410, thereby scraping off the board edge glue generated during the copper clad laminate pressing process to avoid affecting the subsequent process, thereby improving the quality of the product. When the magnet 22 moves upward under the action of the telescopic motor 21, the magnetic flux changes again, thereby generating a reverse current in the rectangular coil 214 and transmitting it to the electromagnet 47, so that the electromagnet 47 presents the same polarity as the magnetic block 48, thereby pushing the magnetic block 48 to drive the scraper 49 away from the electromagnet 47, and performing a secondary scraping of the board edge glue, thereby improving the cleaning effect of the board edge glue.

[0055] like Figure 4 As shown, in the vertical direction, when the right-angle push rod 25 moves to the middle of the push block 28 , the push block 28 contacts the conductive plate 211 .

[0056] In order to make the right-angle push rod 25 move upward during the return stroke, the flexible conductive block on the push block 28 continues to contact the conductive plate 211 for a period of time. At this time, the heating platen 23 no longer blocks the laser emitter 212, so that the receiver 213 receives the signal and transmits it to the control console 5 for online detection and analysis of the flatness, which saves the time of manual secondary detection in the future, saves manpower and improves work efficiency.

[0057] like Figure 7 As shown, the length ratio of the swing rod 34 close to one end of the straight rod 33 and the swing rod 34 away from one end of the straight rod 33 is 1:8.

[0058] In order to make the online thickness detection accuracy of the copper clad laminate more precise during the pressing and forming process, the length ratio of the pendulum rod 34 at both ends of the straight rod 33 is used to compare and amplify the surface height of the copper clad laminate with the preset standard height, so that the device can more keenly capture subtle changes in the thickness of the copper clad laminate, which can greatly improve the detection resolution and thus more accurately detect the thickness.

[0059] like Figure 3 、 4 As shown, the laser transmitter 212 and the receiver 213 are coaxially arranged.

[0060] In order to ensure that the laser emitted by the laser transmitter 212 is accurately received by the receiver 213 and fed back to the control console 5 for analysis, real-time online detection of the flatness of the copper clad laminate during the pressing process is achieved, which facilitates timely detection of waste products, reduces the time for subsequent manual inspection, and improves work efficiency.

[0061] like Figure 3 As shown, the heating platen 23 is electrically connected to the console 5 , and the heating platen 23 is composed of multiple independent heating blocks, each of which is provided with multiple temperature sensors.

[0062] In order to realize the automated production and processing of the device and save human resources, multiple groups of hot pressing blocks control the temperature of the copper clad laminate surface in different zones, accurately control the temperature and keep it synchronized, avoid the warping of the copper clad laminate caused by uneven surface temperature, reduce the scrap rate and improve production quality.

[0063] like Figure 1 As shown, the console 5 is provided with a monitoring screen and a start / stop button.

[0064] In order to facilitate workers to observe the processing process in real time, when the device encounters a fault, workers will be notified in time to stop the operation of the device, and it will be convenient for workers to replace the copper clad laminate.

[0065] Working principle of the present invention:

[0066] When the copper clad laminate to be processed is placed on the limit table 43, the drive motor 41 is controlled by the console 5 to start, which drives the lifting plate 42 to move upward, thereby driving the copper clad laminate on the limit table 43 to move synchronously to the height to be pressed, and then stops moving. At this time, the limit rod 45 moves upward along the inside of the guide slide 11 until the second electrode plate 46 contacts the first electrode plate 12. At this time, the current is transmitted to the telescopic motor 21 through the second electrode plate 46 and the first electrode plate 12. The telescopic motor 21 is started, thereby driving the magnet 22 and the heating press plate 23 to move downward synchronously, contact with the buffer spring 44 and slowly compress, so that the pressure of the heating press plate 23 on the copper clad laminate is more uniform, thereby ensuring that the resin at various places on the copper clad laminate can The plate 24 and the right-angle push rod 25 are driven to move downward until the right-angle push rod 25 contacts the push block 28 and squeezes the push block 28 to move rightward to compress the telescopic spring 29, thereby driving the flexible conductive block on the push block 28 to contact the conductive plate 211, so that part of the current of the console 5 is transmitted to the coil on the arc rod 35 through the conductive plate 211, and the other part of the current is transmitted to the laser emitter 212, so that the laser emitter 212 is started. At this time, the right-angle push rod 25 continues to move downward to the bottom of the straight cylinder 27 driven by the telescopic motor 21 and stops. Stop moving, at this time the console 5 controls the heating press plate 23 to heat the copper clad laminate, thereby realizing the pressing and forming of the copper clad laminate. When the copper clad laminate is pressed, the console 5 controls the telescopic motor 21 to contract, driving the right-angle push rod 25 to extend from the straight cylinder 27, and the push block 28 is pushed to the left and reset under the action of the restoring force of the telescopic spring 29. When the heating press plate 23 leaves the surface of the copper clad laminate, the laser transmitter 212 emits a laser, and the receiver 213 receives the signal and converts it into an electrical signal to the console 5, thereby realizing online detection of the flatness of the copper clad laminate surface. On the other hand, when the magnet 22 moves downward in the rectangular coil 214, the magnetic flux changes, thereby generating a positive current in the rectangular coil 214 and transmitting it to the electromagnetic Iron 47, the electromagnet 47 presents a polarity opposite to that of the magnetic block 48, thereby attracting the magnetic block 48 to drive the scraper 49 toward the electromagnet 47 while contracting the multi-stage telescopic rod 410, thereby scraping off the board edge glue generated during the copper clad board pressing process to avoid affecting the subsequent process, thereby improving the quality of the product. When the magnet 22 moves upward under the action of the telescopic motor 21, the magnetic flux changes again, thereby generating a reverse current in the rectangular coil 214 and transmitting it to the electromagnet 47, so that the electromagnet 47 presents the same polarity as the magnetic block 48, thereby pushing the magnetic block 48 to drive the scraper 49 away from the electromagnet 47, and performing a secondary scraping of the board edge glue, thereby improving the cleaning effect of the board edge glue.

[0067] When the telescopic motor 21 drives the flat plate 24 to move downward until the heating plate 23 is in full contact with the copper clad laminate, the flat plate 24 pushes the pendulum rod 34 to rotate downward around the straight rod 33, and the other end rotates upward along the arc rod 35. The current is transmitted to the coil on the arc rod 35 through the conductive plate 211. When the conductive ring iron on the pendulum rod 34 is in contact with the coil, the effective number of turns of the coil changes, and the resistance value changes synchronously, thereby causing the current value transmitted to the console 5 by the pendulum rod 34 to change. The console 5 detects whether the current change value at this time exceeds the preset range. If it exceeds, the console 5 adjusts the distance the heating plate 23 descends, thereby realizing timely adjustment of the copper clad laminate with thickness deviation during the pressing process, reducing the scrap rate and improving production quality.
