The surface of the second toothed plate 54 is slidably connected with a stop collar 55, the stop collar 55 is connected to the sliding plate 3, and the stop collar 55 is used for limiting the sliding orientation of the second toothed plate 54, so that the sliding of the second toothed plate 54 is more stable.

The second toothed plate 54 moves forward, and thus rotates the first gear 611 engaged thereunder. And then drives the crank 612 to rotate, and converts the rotation force into a pressing force, so that the pressing plate 613 presses down to provide a pressing driving force.

One end of the second link 636 is connected to a first link 635, and the first link 635 is connected to the slide plate 3. As the cylinder 51 continues to extend, the sliding sleeve 632 will now force the compression of the pressure spring 634, initially in contact, followed by contact pressurization, while the downward pressure acts on the pressure spring 634, with the pressure spring 634 providing the pressure on the doctor blade 9.
In addition, the display pressure regulating device 62 includes a display disc 622, the display disc 622 is connected to the sliding plate 3, a rotating shaft 621 is connected to the shaft center of the display disc 622, one end of the rotating shaft 621 is connected to a pointer 626, and the other end of the rotating shaft 621 is connected to the associated assembly 64.

When the pointer 626 contacts with the adjusting plate 623 in a rotating way, the extension of the air cylinder 51 will not drive the scraper 9 to move downwards for pressurizing, but drive the whole sliding plate 3 to move forwards through the connection of the pull rod 643, so that printing is realized.
Example 2A component printing Process
Step S1: acquiring a printed electronic component;
step S2: positioning electronic components;
placing the electronic printing electronic components on the base 1 below the silk screen plate 2, and fixing the electronic printing electronic components by a fixing device; the fixing device is generally a plate material with a groove, the electronic components are directly placed in the groove matched with the external shape, and the actual fixing device is actually arranged according to the shape of the electronic components.
Step S3: regulating ink;
the dye to be printed is prepared to be of corresponding consistency, and an operator is required to prepare the dye according to a proportion because the consistency directly solves the definition in the printing process, and then the dye is placed above the silk screen plate 2; the silk screen plate 2 is provided with a groove space for placing the dye, and the liquid dye is only required to be placed in the groove, so that the dye can be printed on the surface of an electronic component through the silk screen plate 2 along with the sliding of the scraper 9.
Step S4: the scraper is pressed down to press down the scraper,
the extension of the control cylinder 51 will drive the intermediate gear 52 to move forward, then slide along with the forward movement of the two first toothed plates 53, further drive the rotation of the first gear 611 meshed below, then drive the rotation of the crank 612, press the control pressing plate 613 downward, drive the expansion of the second connecting rod 636 and the third connecting rod 637 through the elastic connection of the pressure spring 634 when the connecting sheet 631 slides, and finally control the downward movement of the scraper 9; this step is mainly to move the doctor blade 9 downwards into contact with the wire mesh sheet 2 or with the dye, so that the doctor blade 9 prints the dye on the upper surface of the electronic component during the forward movement.
Step S5: the pressure is protected,
when the scraper 9 is pressed down, the sliding sleeve 632 will slide on the sliding column 633 to compress the pressure spring 634, and the third toothed plate 641 moves down to drive the pointer 626 to rotate via the engagement of the gears, so that the pointer 626 rotates to form a contact barrier with the adjusting plate 623, and further the continued downward movement of the scraper 9 is limited; since the pressure is not fixed when the doctor blade 9 is pressed down, which will affect the printed product, it may be clear in part and unclear in part, so that it is necessary to ensure that the pressure at the time of pressing down remains uniform at the time of printing. The overpressure will directly cause the doctor blade 9 to press against the screen plate 2, which will contact the electronic components and cause damage to the electronic components.
Step S6: the printing is performed by sliding the printing plate,
then, as the air cylinder 51 continues to extend, the two first toothed plates 53 drive the second toothed plates 54 to slide, and the whole sliding plate 3 is driven to horizontally move through the connection of the pull rods 643, so that the doctor 9 can transversely slide on the screen plate 2 for printing. By utilizing the preliminary extension of the air cylinder 51, the power is converted into the downward pressure, so that the scraper 9 moves downwards, then the extension is continued, the scraper 9 is pressurized to be under a certain pressure value, and finally the continuous extension state drives the scraper 9 to move forwards, so that the printing operation is realized.
The electrical components are all connected with an external main controller and 220V mains supply, and the main controller can be conventional known equipment for controlling a computer and the like.
The working principle is that firstly, electronic printing electronic components are placed on a base 1 and below a silk screen plate 2, then the electronic printing electronic components are fixed in position through a fixing device, and the fixing device is generally a plate material with a groove, and the electronic components are directly placed in the groove matched with the external shape. Then, the printed dye is placed above the silk screen plate 2, the extension of the control cylinder 51 drives the intermediate gear 52 to move forward, the intermediate gear 52 is provided with two first toothed plates 53, the two first toothed plates 53 are pushed forward by the intermediate gear 52 and move forward synchronously, if the single toothed plate cannot be realized, the two toothed plates form a clamping-like state, and then move forward along with the two first toothed plates 53 and the second toothed plate 54, so that the first gear 611 meshed below is driven to rotate. Then, the crank 612 is driven to rotate, the rotating force is converted into a downward pressure, the pressing plate 613 is pressed down, the downward pressure is transmitted to the connecting sheet 631 through the connection of the shaft rod, the connecting sheet 631 drives the sliding sleeve 632 to slide on the sliding column 633, the second connecting rod 636 and the third connecting rod 637 are driven to be unfolded through the elastic connection of the pressure spring 634, the angle of the second connecting rod 636 and the third connecting rod 637 is enlarged, so that the scraper 9 at the moment moves downwards and presses the wire mesh plate 2, and the pressure spring 634 is stressed and compressed above the electric components, the sliding sleeve 632 drives the third toothed plate 641 to move downwards when the sliding sleeve 632 moves downwards and slides, the pointer 626 on the rotating shaft 621 is driven to rotate through the meshing of the gears, the pressure scale mark is arranged on the display disc 622, the pressure value contacted with the wire mesh plate 2 is displayed according to the rotation of the pointer 626, and the pressure protection is realized when the pointer 626 rotates to be blocked by contact with the adjusting plate 623. At this time, the continued pushing of the air cylinder 51 will drive the whole sliding plate 3 to move horizontally through the connection between the second toothed plate 54 and the pull rod 643, and the doctor 9 will perform the horizontal sliding printing on the screen plate 2.
