[0014] The present invention further provides a PCB production process with a combined function, wherein the production process uses the above-mentioned PCB production equipment with a combined function, and the production process comprises the following steps:

[0015] Step S1: Fix the silk screen with multiple circuit patterns on two silk screen fixing components, place the circuit board that needs to be printed with the circuit diagram on the suction cup body, turn on the suction cup switch, and the circuit board is adsorbed on the top of the suction cup body.

[0016] Step S2: Move the screen fixing assembly downward until the screen abuts against the top of the circuit board, control the printing assembly to move to a suitable height, sprinkle ink on the screen, and test the height of the ink return piece and the scraper piece.

[0017] Step S3: After adjusting the height, start the equipment, the scraper moves downward and abuts against the wire mesh, the wire mesh is slightly bent downward and straightened, the scraper will slide upward to squeeze the return spring, the return spring contracts so that the extrusion plate can be pressed upward to shrink the airbag, and the airbag is squeezed to release the gas inside.

After the high-pressure airflow rushes to the scraper, it flows to the ink under the guidance of the scraper, so that the volatile toxic gas of the ink is blown to the side away from the scraper by the high-pressure airflow. After the ink is applied, check whether the pattern on the circuit board is complete and proceed to the next procedure.

[0019] The present invention provides a reset spring. When the scraper member is tested, the scraper motor is started. The scraper member moves downward and is likely to hit the circuit board or the suction cup body, causing damage to the circuit board, the suction cup body and the scraper. By providing an air bag and a buffer reset component, when the scraper member is tested, if the sliding section moves too low, the scraper motor is started. When the scraper member moves downward and abuts against the circuit board or the suction cup body, the scraper will slide upward and squeeze the reset spring according to the action force and the reaction force. The reset spring is compressed upward and contracts, preventing the scraper from hitting the circuit board or the suction cup body, causing damage to the circuit board, the suction cup body and the scraper. By setting the air bag, after adjusting the height, the equipment is started, the scraper moves downward and abuts against the screen, and the screen is slightly bent downward and straightened, so that the ink can pass through the screen better, so that the ink can be printed more clearly on the circuit board. The return spring is relatively thin, and the scraper will slide upward to squeeze the return spring. The return spring contracts so that the extrusion plate can be pressurized upward to shrink the air bag. The air bag is squeezed to release the gas inside, and the gas flows out from the air outlet groove to form a flushing airflow F1. The flushing airflow F1 enters the buffer space to form a high-pressure airflow, and the scraper squeezes the return spring upward to further compress the buffer space, so that the pressure in the buffer space rises further, and the high-pressure air flows to the low-pressure outside, so that the high-pressure airflow can rush to the middle of the scraper through the air dispersion groove. After the high-pressure airflow rushes to the scraper, it is guided by the scraper to flow to the ink, so that the volatile toxic gas of the ink is blown to the side away from the scraper by the high-pressure airflow, reducing the toxic gas absorbed by the personnel when the ink evaporates during printing. At the same time, the return spring can quickly restore the airbag to its original state to prepare for the next printing, and the airbag can further provide a buffer for the scraper. The structure of the present invention is ingenious, which can prevent accidents during testing and reduce the risk of workers inhaling excessive volatile gases from ink during operation.

[0044] Step S4: Gas flows out from the air outlet groove 71 to form a flushing airflow F1, and the flushing airflow F1 enters the buffer space 446 to form a high-pressure airflow, and the scraper 445 squeezes the return spring 82 upward to further compress the space of the buffer space 446, so that the pressure in the buffer space 446 rises further, and the high pressure flows to the low pressure outside. After the high-pressure airflow rushes to the scraper 445, the high-pressure airflow flows to the ink under the guidance of the scraper 445, so that the toxic gas volatilized by the ink is blown to the side away from the scraper 445 by the high-pressure airflow. After the ink is applied, check whether the pattern on the circuit board is complete and proceed to the next procedure.

[0045] During installation: the suction cup assembly 20 and the moving assembly 30 are fixedly installed on the top of the support assembly 10, the printing assembly 40 and the two screen fixing assemblies 50 are installed on the side walls of the moving assembly 30, the sliding section 41 is slidably installed on the side walls of the moving assembly 30, the ink return component 43 is installed at one end of the top of the fixed section 42, the scraper component 44 is installed at the other end of the top of the fixed section 42, the airbag 70 and the buffer reset assembly 80 are both installed inside the scraper component 44, the suction cup fixing seat 21 is fixedly installed on the top of the support platform 12, the suction cup switch 22 is installed on the side wall of the suction cup fixing seat 21, the suction cup body 23 is installed on the top of the suction cup fixing seat 21, the fixed base 31 is fixedly installed on one end of the top of the support platform 12, the bottom of the Y-axis moving frame 32 is fixedly installed on the top of the fixed base 31, and the X-axis moving frame 33 is slidably installed on the side wall of the Y-axis moving frame 32. The ink return motor 430 is fixedly installed at one end of the top of the fixed section 42, the scraper motor 440 is fixedly installed at the other end of the top of the fixed section 42, the two screen fixing components 50 are respectively installed at both ends of the side walls of the X-axis movable frame 33, the sliding frame 51 is interactively installed on the side walls of the X-axis movable frame 33, multiple fixing parts 52 are all installed on the top of the sliding frame 51, the airbag 70 is installed in the buffer space 446, and the extrusion plate 83 is installed in the middle of the reset spring 82.

[0046] When using: 1. Fix the screen with multiple circuit patterns on the two screen fixing components 50, place the circuit board that needs to be printed with the circuit diagram on the suction cup body 23, turn on the suction cup switch 22, and the circuit board is adsorbed on the top of the suction cup body 23 to prevent the circuit board from shaking during printing. Move the screen fixing component 50 downward until the screen is against the top of the circuit board, manipulate the printing component 40 to move to a suitable height, sprinkle ink on the screen, test the height of the ink return component 43 and the scraper component 44, when the user moves the sliding section 41 too low, start the scraper motor 440, and the scraper component 44 is tested. When the scraper 44 moves downward, it is easy to hit the circuit board or the suction cup body 23, causing damage to the circuit board, the suction cup body 23 and the scraper 445. By setting the air bag 70 and the buffer reset component 80, when the scraper member 44 is tested, when the sliding section 41 moves too low, the scraper motor 440 is started, and when the scraper member 44 moves downward and abuts the circuit board or the suction cup body 23, according to the action force and reaction force, the scraper 445 will slide upward to squeeze the reset spring 82, and the reset spring 82 is compressed upward to prevent the scraper 445 from hitting the circuit board or the suction cup body 23, causing damage to the circuit board, the suction cup body 23 and the scraper 445.

[0047] 2. After adjusting the height, start the equipment, the scraper 44 moves downward and abuts against the screen, the screen is slightly bent downward and straightened, so that the ink can pass through the screen better, so that the ink can be printed more clearly on the circuit board, the return spring 82 is relatively thin, the scraper 445 will slide upward to squeeze the return spring 82, the return spring 82 contracts so that the extrusion plate 83 can be pressed upward to shrink the airbag 70, the airbag 70 is squeezed to release the gas inside, the gas flows out from the air outlet groove 71 to form the flushing airflow F1, the flushing airflow F1 enters the buffer space 446 to form a high-pressure airflow, and the scraper 445 The upward compression of the return spring 82 further compresses the buffer space 446, causing the pressure in the buffer space 446 to rise further. The high-pressure air flows toward the low-pressure air outside, allowing the high-pressure airflow to rush toward the middle of the scraper 445 through the air dispersion groove 447. After the high-pressure airflow rushes toward the scraper 445, it is guided by the scraper 445 to flow toward the ink, so that the toxic gases volatilized by the ink are blown to the side away from the scraper 445 by the high-pressure airflow, reducing the toxic gases absorbed by the scraper 445 during printing and smoothing the ink, so that the ink is spread evenly on the screen. At the same time, the return spring 82 can quickly restore the airbag 70 to its original state to prepare for the next printing, and the airbag 70 can further provide a buffer for the scraper 445. The multiple return springs 82 also ensure that the bottom of the scraper 445 is parallel to the lower end of the slide 51. If the bottom of the scraper 445 is not parallel to the lower end of the slide 51, the lowest point of the scraper 445 will first contact the screen. As the scraper 445 continues to press downward, the return spring 82 at the lowest point of the scraper 445 contracts until the highest point of the bottom of the scraper 445 contacts the screen. The scraper 445 is parallel to the lower end of the slide 51, allowing the pattern on the screen to be completely printed on the circuit board. At the same time, the curved bottom of the scraper 445 can prevent excess ink on the screen from moving out of the range of the scraper 445 to a certain extent, reducing waste.

[0048] 3. A heating plate is installed inside the airbag 70, a first conductive plate is installed on the inner wall of the fixed frame (444), a power supply is installed on the outer wall of the fixed frame (444), a second conductive plate is installed on the side wall of the scraper 445, the first conductive plate and the second conductive plate are both electrically connected to the conductive plate, and the heating plate is electrically connected to the first conductive plate. When the scraper 445 presses the reset spring 82 upward, the second conductive plate will abut against the first conductive plate, the circuit is turned on, the heating plate heats up, and the high-pressure airflow is heated. After the high-pressure airflow is heated, it can heat the reset spring 82, so that the reset spring 82 softens. The softened reset spring 82 has stronger elasticity, thereby increasing the high-pressure airflow.

[0049] The bottom of the scraper 445 is connected to a plastic scraper. The heated, high-pressure airflow heats the plastic scraper, softening it and allowing it to more closely contact the screen, allowing the pattern on the screen to be more completely printed on the circuit board. The heated, high-pressure airflow also heats the ink, drying it faster on the circuit board.

[0050] The present invention sets a reset spring 82. When the scraper member 44 is tested, the scraper motor 440 is started. The scraper member 44 moves downward and easily hits the circuit board or the suction cup body 23, causing damage to the circuit board, the suction cup body 23 and the scraper 445. By setting the airbag 70 and the buffer reset assembly 80, when the scraper member 44 is tested, when the sliding section 41 moves too low, the scraper motor 440 is started. When the scraper member 44 moves downward and abuts against the circuit board or the suction cup body 23, according to the action force and reaction force, the scraper 445 will slide upward and squeeze the reset spring 82. The reset spring 82 is compressed upward and contracts to prevent the scraper 445 from hitting the circuit board or the suction cup body 23, causing damage to the circuit board, the suction cup body 23 and the scraper 445. By setting the airbag 70, after adjusting the height, start the equipment, the scraper member 44 moves downward to abut against the screen, and the screen is slightly bent downward and straightened, so that the ink can pass through the screen better, so that the ink can be printed more clearly on the circuit board. The return spring 82 is relatively thin, and the scraper 445 will slide upward to squeeze the return spring 82. The return spring 82 contracts so that the extrusion plate 83 can be pressed upward to shrink the airbag 70. The airbag 70 is squeezed to release the gas inside. The gas flows out from the air outlet groove 71 to form a flushing airflow F1, and the flushing airflow F1 enters the buffer space 446 to form The high-pressure airflow and the upward pressure of the scraper 445 on the return spring 82 further compress the buffer space 446, causing the pressure in the buffer space 446 to rise further. The high-pressure air flows toward the low pressure outside, allowing the high-pressure airflow to rush toward the center of the scraper 445 through the air dispersion groove 447. After the high-pressure airflow rushes toward the scraper 445, it is guided by the scraper 445 to flow toward the ink, so that the toxic gases volatilized by the ink are blown away from the scraper 445 by the high-pressure airflow, reducing the toxic gases absorbed by the personnel when the ink evaporates during printing. At the same time, the return spring 82 can quickly restore the airbag 70 to its original state to prepare for the next printing, and the airbag 70 can further provide a buffer for the scraper 445. The present invention has an ingenious structure that can prevent accidents during testing and reduce the risk of excessive inhalation of volatile gases from the ink by personnel during operation.
