The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

detailed description

Referring to FIG. 1 and FIG. 2 , the screen printing machine 1 includes a frame 10 , an embossing mechanism 20 , and a spraying device 30 . The frame 10 places several workpieces (not shown in the figure) and includes several screen printing screens 11 covering the workpieces. The embossing mechanism 20 and the spraying device 30 are used to print specific patterns or characters on the surface of the workpiece through the screen printing screen 11 .

The frame 10 includes a support surface 12 and a guide plate 13 above the support surface 12 , wherein the support surface 12 is provided with a plurality of receiving portions 14 . Each receiving portion 14 defines a receiving chamber 140 for receiving workpieces. Each screen printing screen 11 is rotatably connected to the support surface 12 , and is located near a receiving portion 14 , and can rotate to cover the receiving cavity 140 of the receiving portion 14 .

The embossing mechanism 20 includes a driving device 21 arranged on the guide plate 13, two fixing parts 23, and a transmission rod 22 for transmitting the power of the driving device 21 to the fixing plate 23, wherein the two fixing plates 23 are respectively fixed to the transmission Both sides of the rod 22. The embossing mechanism 20 also includes a cylinder 24 and a scraper 25 fixedly arranged between the two fixed plates 23 , wherein the cylinder 24 is used for coating photosensitive glue and ink on the screen printing screen 11 . When the driving device 21 works, it can respectively drive the embossing mechanism 20 to slide along the above-mentioned guide plate 13, and the driving device 21 can also drive the transmission rod 22 to swing, thereby adjusting the position of the cylinder 24 and the scraper 25 relative to the screen printing screen 11.

Referring to Fig. 3 together, described spraying device 30 comprises housing 31 between above-mentioned supporting surface 12 and guide plate 13, a carrying plate 32 and some containers 33 that are fixed on this carrying plate 32, and are used to drive A motor 34 rotates the carrier plate 32 . The casing 31 includes a cavity 310 with an opening facing the embossing mechanism 20 , wherein the carrier board 32 and the container 33 are located in the cavity 310 . The container 33 is used to hold the photosensitive glue or ink, and it can automatically eject the photosensitive glue or ink when it is squeezed from the outside. The motor 34 is located above the housing 31 and includes an output shaft 340 , wherein the output shaft 340 passes through the top wall of the housing 31 , and an end of the output shaft 340 is fixedly connected to the bearing plate 32 .

The drive device 21 and the motor 34 are commonly connected to a control device 40 , and the control device 40 is used to control the drive device 21 and the motor 34 to work. When working, the control device 40 controls the driving device 21 to work and drives the roller 24 to move into the spraying device 30 and squeeze the container 33 containing the photosensitive glue, so that the photosensitive glue is sprayed on the surface of the roller 24 . The control device 40 controls the driving device 21 to drive the transmission rod 22 to swing to the position where the cylinder 21 can contact the screen printing screen 11 of the frame 10 and move along the guide plate 13 to coat the photosensitive glue on the screen printing screen 11 . The photosensitive glue on the above-mentioned screen printing screen 11 is subjected to a baking process and an exposure process, so that a mesh part that blocks ink from passing is formed on the screen printing screen 11 .

The control device 40 controls the motor 34 to drive the bearing plate 32 to rotate, so that the containers 33 filled with ink can contact the cylinders 24 respectively. In the same way as above, the cylinder 24 can apply ink to the screen printing screen 11 .

Finally, the control device 40 controls the driving device 21 to work so that the transmission rod 22 swings to the top position where the scraper 25 and the screen printing screen 11 form a certain angle, and drives the scraper 25 to move along the guide plate 13 to press the ink into the mesh of the screen printing screen 11 , and then form a specific pattern or text on the surface of the workpiece. In this embodiment, the included angle between the scraper 25 and the screen printing screen 11 is about 75°, so that the scraper 25 can evenly scrape the ink through the meshes of the screen printing screen 11 .

In this embodiment, the screen printing machine 1 further includes an exposure device 50 disposed on the frame 10 and opposite to the spraying device 30 , wherein the exposure device 50 is used to perform an exposure process on the photosensitive glue of the above-mentioned screen printing screen 11 . Because the photosensitive adhesive has weak light sensitivity before it is dried, but after drying, the light sensitivity will be very sensitive. The exposure device is placed on the frame 10, which facilitates the exposure process immediately after the screen printing screen 11 is dried.

While there has been illustrated and described the preferred embodiment of the invention, those skilled in the art will appreciate that various changes and modifications can be made without departing from the true scope of the invention. It is therefore intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention encompasses all embodiments within the scope of the appended claims.
