As shown in fig. 1-2, to solve the above technical problem, the present embodiment provides a screen printing squeegee device, which is installed on a screen printing machine, and is used for pushing and squeezing ink on a worktable and performing a screen printing operation. Comprises a sliding plate 60, a supporting seat 30 fixed on the sliding plate 60, a scraper 10 positioned below the supporting seat 30, and a driving component arranged above the supporting seat 30. The sliding plate 60 is slidably disposed on the guide rail of the screen printing machine, and the sliding plate 60 can move linearly along the guide rail by using the transmission mode of the conveyor belt. The middle position of the sliding plate 60 is provided with a supporting seat 30, and the supporting seat 30 is rectangular block-shaped and is fixed on the sliding plate 60 through bolts.
Further, a through hole is formed in the supporting seat 30, the linkage rod 20 is fixed on the supporting seat 30, the linkage rod 20 is rotatably arranged below the supporting seat 30, the linkage rod 20 is fixedly connected with the scraper 10, the scraper 10 and the linkage rod 20 are arranged at a certain angle, the sliding plate 60 moves to drive the supporting seat 30 and the scraper 10 of the supporting seat 30 to move together, as shown in fig. 3, the scraper 10 is attached to the stencil 12 of the workbench, and therefore the scraper 10 pushes and extrudes ink on the stencil 12.
The linkage rod 20 is T-shaped, screw holes are formed in two ends of a T-shaped cross rod of the linkage rod 20, bosses matched with the T-shaped cross rod are formed in two ends of the scraper 10, and the bolt 11 penetrates through the bosses and is fixedly connected with the screw holes of the linkage rod 20. The connection mode can lead the scraper 10 to be fixed with the linkage rod 20 in a rotatable way, realizes that the scraper 10 forms an angle with the stencil 12 on the workbench, is more beneficial to the scraper 10 to push ink, and improves the screen printing quality. Meanwhile, according to the actual production condition, the scraper blades 10 with different sizes can be replaced for circuit boards with different sizes of silk screen printing, the connecting structure enables the scraper blades 10 to be replaced conveniently, and the production efficiency is improved.
In order to realize that the linkage rod 20 can rotate on the supporting seat 30 or move in the vertical direction, the linkage rod 20 is installed in the through hole of the supporting seat 30 through the bearing seat 21. The bearing seat 21 has the function of supporting the linkage rod 20, and can enable the linkage rod 20 to rotate around the axis of the bearing seat 21, and also enable the linkage rod 20 to move along the axis direction of the bearing seat 21.
After the ink is pushed in the positive direction by the scraper 10 on the stencil 12, the ink needs to be pushed in the reverse direction, and the ink is accumulated on one surface of the scraper 10 in the positive direction, and the ink needs to be turned over by 180 degrees when being pushed in the reverse direction, so that the ink is continuously pushed in the reverse direction on the surface on which the ink is accumulated. In order to solve the above problem, in this embodiment, a driving assembly is disposed on the supporting seat 30, and the scraper 10 is linked with the driving assembly through a linkage rod 20. Wherein the drive assembly includes a timing belt assembly for driving rotation of the screed 10 and a pneumatic assembly for driving longitudinal movement of the screed 10.
Specifically, the synchronous belt assembly comprises a rotating shaft 51 fixed on the supporting seat 30, a servo motor 53 fixed above the rotating shaft 51, and a transmission belt 52 for linking the rotating shaft 51 and the linking rod 20. The servo motor 53 is fixed on the sliding plate 60, the servo motor 53 is connected with the rotating shaft 51 and drives the rotating shaft 51 to rotate, the rotating shaft 51 is in transmission connection with the linkage rod 20 through the transmission belt 52, the rotation of the rotating shaft 51 drives the linkage rod 20 to rotate through the transmission belt 52, and then the scraper 10 is turned over for 180 degrees. Wherein, the top of the rotating shaft 51 is provided with an edge boss, which can prevent the driving belt 52 from deviating upwards to separate from the rotating shaft 51 in the rotating process, and has the function of stabilizing the rotation of the driving belt 52.
In the process that the scraper 10 is turned over by 180 degrees, the scraper 10 is always in contact with the stencil 12 on the workbench, and in order to prevent the scraper 10 from rubbing against the stencil 12 in the rotating process and fully utilize the ink accumulated on the scraper 10, an upward lifting action is required before the scraper 10 rotates, and therefore, a pneumatic component for driving the scraper 10 to move in the vertical direction is fixed above the linkage rod 20.
The pneumatic assembly is a cylinder 40 fixed above the linkage rod 20, the cylinder 40 is fixed on the support plate 30 through a connecting plate 42, hole sites which are vertically arranged side by side and can be in bolt connection with the cylinder 40 are arranged on the connecting plate 42, the cylinder 40 is connected with the hole sites at different positions, the cylinder 40 can be installed at different height positions, and the installation height of the cylinder 40 can be adjusted.
In order to realize the fixed connection between the cylinder 40 and the linkage rod 20, a groove for accommodating the telescopic rod of the cylinder 40 is arranged at the top end of the linkage rod 20, a cover plate 41 capable of sealing the groove is further arranged on the linkage rod 20, the cover plate 41 is rotatably fixed at the top end of the linkage rod 20 through threads, and the telescopic rod of the cylinder 40 is fixed in the groove at the top end of the linkage rod 20 through the cover plate 41. When the scraper 10 is moved to the place and needs to be turned over, the air cylinder 40 starts and lifts the telescopic rod, and the linkage rod 20 is vertically moved upwards by pulling the cover plate 41, so that the scraper 10 leaves the surface of the stencil 12.
In order to realize that the vertical movement and the rotary movement of the linkage rod 20 are performed simultaneously, the contact between the transmission belt 52 and the rotating shaft 51 and the contact between the linkage rod 20 and the transmission belt 52 are both in rack meshing contact transmission, and a rack on the linkage rod 20 can slide in the vertical direction relative to a rack on the transmission belt 52, so that the linkage rod 20 does not influence the meshing transmission with the transmission belt 52 while moving in the vertical direction, and the vertical movement and the rotary movement of the linkage rod 20 are performed simultaneously.
To sum up, through set up the rotatory conveyer belt subassembly of drive scraper blade and the pneumatic assembly that the vertical direction of drive scraper blade removed on the slider that the drive scraper blade removed, realize that the scraper blade leaves the stencil surface when moving in place on the stencil to accomplish and overturn 180 and carry out reverse promotion printing ink, realize when the reverse ink scraping of scraper blade, the printing ink of piling up at the scraper blade continues by make full use of, improves silk screen printing efficiency, solves the not good problem of silk screen printing quality.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
