Description

Technical Field

[0001] The invention relates to the field of carrier board manufacturing, in particular to a printing ink machine for automatically removing ink and a working method thereof. Background Art

[0002] The substrate is a key part of the connection between electronic components and circuit boards. The ink printing process in the substrate manufacturing process is an important step to achieve accurate circuit pattern transfer. In this process, the printer accurately prints conductive ink or other functional inks to the predetermined position of the substrate to form circuit connections or realize other electronic functions.

[0003] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0004] 1. When printing ink, too much ink attached to the stencil may reduce the accuracy of circuit pattern transfer, affecting the yield and good rate of the substrate;

[0005] 2. When removing excess ink from the screen, it is usually done manually or by using a cleaning device to clean it back and forth multiple times, which takes a long time and has low oil removal efficiency. Summary of the invention

[0006] The present invention solves the technical problem in the prior art that excessive excess ink attached to the screen may interfere with the printing of circuit patterns by providing a printing ink machine for automatically removing ink and a working method thereof, thereby improving the finished product rate and good product rate of substrate printing. In addition, the embodiment of the present application also controls the movement of the oil removal device through a sensor, so that the oil removal device can determine the next movement trajectory of the oil removal device according to the actual position of the screen and the oil removal device, and can purposefully and accurately remove excess ink from the bottom of the screen, thereby effectively removing excess ink from the bottom of the screen without the need for multiple oil removals, thereby shortening the time for a single oil removal.

[0007] The embodiment of the present application provides an ink printing machine for automatically removing ink, comprising: a back plate; an ink printing device connected to one side of the back plate, comprising: an ink brush, the ink brush being arranged below the ink printing device; a screen plate, being arranged below the ink brush; a screen plate fixing plate, being connected to two opposite sides of the screen plate; a carrier track, being arranged below the screen plate; guide rails, being arranged on both sides of the carrier track; an oil removal device, being installed on the guide rails; a bottom box, being arranged below the carrier track; a first sensor, being arranged on the back plate, on the side of the screen plate; a second sensor, being arranged on the guide rails; and a third sensor, being arranged on the guide rails.

[0008] Furthermore, the oil removal device can remove excess ink under the screen by any means, wherein the preferred ink removal method is adsorption or wiping. When the screen is pressed down and the carrier printing is completed, the oil removal device moves under the screen to remove excess ink to avoid excessive ink on the screen during the next printing, which affects the yield.

[0009] Furthermore, the bottom box is a hollow cavity, which can be used to place other circuit devices, reduce the external volume of the device, and provide external protection for important circuit devices, such as a control host.

[0010] Furthermore, the second sensor is arranged at an end point of the working path of the oil removal device, and is used to detect the position of the oil removal device. The control host then controls whether the circuit switch in the oil removal device is closed or not according to the detection result, thereby realizing the control of the oil removal device and completing the removal of excess ink at the bottom of the screen.

[0011] Furthermore, the third sensor is arranged at the other end point of the working path of the oil removal device to detect the position of the oil removal device. The control host then controls whether the circuit switch in the oil removal device is closed or not according to the detection result, thereby controlling the oil removal device and completing the removal of excess ink at the bottom of the screen.

[0012] In addition, the present invention also provides a method for automatically removing ink, which is applicable to the printing ink machine for automatically removing ink according to claim 1, and comprises the following steps:

[0013] S0: screen pressing down;

[0014] S1: The first sensor detects that the screen begins to press down, and controls the main switch of the oil removal device circuit to close;

[0015] S2: The second sensor detects the oil removal device, closes the first switch, and the ink brush applies ink to the stencil. After the circuit pattern is printed, the stencil is lifted;

[0016] S3: The oil removal device is started and moves from one end of the working path to the other end to complete the removal of ink;

[0017] S4: The second sensor cannot detect the oil removal device and disconnects the first switch;

[0018] S5: The first sensor detects that the screen plate starts to rise, and the main switch of the oil removal device circuit is turned off;

[0019] S6: the screen is pressed down;

[0020] S7: The first sensor detects that the screen plate starts to press down, and controls the main switch of the oil removal device circuit to close;

[0021] S8: The third sensor detects the oil removal device, closes the second switch, and the ink brush moves to

[0022] The stencil is coated with ink, and after the circuit pattern is printed, the stencil is lifted;

[0023] S9: The oil removal device is started, and the oil removal device moves from one end of the working path to the other end to complete the removal of ink;

[0024] S10: The third sensor cannot detect the oil removal device, and the second switch is disconnected;

[0025] S11: The first sensor detects that the screen plate starts to rise, and controls the main switch of the oil removal device circuit to be disconnected.

[0026] In the above steps, multiple sensors are used to cooperatively control the oil removal device. According to the detected actual positions of the screen and the oil removal device, the movement path of the oil removal device is determined for the next step, so that the oil removal device can accurately remove excess ink from the bottom of the screen.

[0027] Furthermore, there is no particular order between steps S1 and S2, and between steps S7 and S8, and they can be performed in any order, or both steps can be performed simultaneously.

[0028] Furthermore, there is no particular order between steps S4 and S5, and between steps S10 and S11, and they can be performed in any order, or both steps can be performed simultaneously.

[0029] Furthermore, by repeating the above steps and continuously using the oil removal device to remove excess ink on the screen, by continuously completing the cycle of "pressing the screen down - applying ink to the screen - raising the screen - using the oil removal device to remove excess ink from the bottom of the screen after printing", the automatic removal of excess ink from the bottom of the screen can be achieved when the printing ink machine is working.

[0030] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0031] 1. By setting up an oil removal device, the technical problem in the prior art that too much ink attached to the screen during printing ink may reduce the accuracy of circuit pattern transfer is effectively solved, thereby improving the finished product rate and good product rate of the printed substrate.

[0032] 2. Through the coordinated cooperation of multiple sensors, the oil removal device is controlled. According to the actual position of the screen and the oil removal device detected by the sensor, the working path of the oil removal device is determined, and the excess ink under the screen is precisely removed purposefully, thereby shortening the ink removal time and achieving efficient printing on the printing substrate.
