Abstract

The pressure sensing controller is respectively connected with the driving motor and the pressurizing part and is used for sensing the contact pressure reacted when the pressurizing part applies pressure, so that the driving motor is controlled to drive the pressurizing part to lift and adjust the position timely.

Description

Induction type pressure device of automatic screen printer

Technical Field

The utility model relates to an automatic induction type pressure device of screen printing machine especially relates to one kind and can effectively will scrape the pressure that the scraper on the blade holder reacted immediately, orders about and drives this scraper seat and goes up and down to reach good printing effect, and then improve the quality and the precision of processing.

Background

Screen printing is known as universal printing, and can be used for printing on various printing materials such as various plastics, textiles, metals, glass, ceramics, printed circuit boards and the like, and further is widely applied to the industrial fields of advertisement, art, building, publishing, printing and dyeing, electronics and the like, particularly the electronic industry, the occupancy rate of the screen printing technology is up to 90%, and the importance of screen printing is seen from this.

In the field of screen printing, a machining operation is performed on a workpiece through a scraper or a roller, the machine is a very common mechanical structure, and for a screen printing machine for the electronic industry, a table plate is arranged on a machine table and used for bearing a printed circuit board, a left frame seat and a right frame seat are respectively arranged on a left cantilever and a right cantilever of the table plate and used for erecting a screen frame with a hollow pattern screen, and a group of scrapers are arranged above the screen frame, so that after liquid materials such as printing ink or glue are poured onto the screen plate manually, the printing ink or the glue is printed on the printed circuit board by the scrapers.

SUMMERY OF THE UTILITY MODEL

However, although the above machine design can achieve the printing effect, the scraper still needs to rely on the experience of the user to operate the working pressure of the scraper on the workpiece during the operation so as to achieve the good printing effect.

The main object of the present invention is to provide an induction type pressurizing device of an automatic screen printing machine, which has a simple structure and can immediately raise and lower the scraper by the pressure of the scraper reaction.

To achieve the above object, the present invention provides an inductive pressure device for an automatic screen printing machine, configured to be disposed on a working arm of the automatic screen printing machine, the inductive pressure device includes a driving motor, a pressure-applying portion and a pressure-sensitive controller, the pressure-applying portion is configured to perform a printing operation when applying pressure to a workpiece, the pressure-sensitive controller is connected to the driving motor and the pressure-applying portion respectively, the pressure-sensitive controller is configured to sense a contact pressure that is reacted when the pressure-applying portion applies pressure, so as to control the driving motor to drive the pressure-applying portion to adjust a position of the pressure-applying portion in a timely manner.

In practice, the pressing portion includes a scraper or roller for pressing down on a workpiece.

For further understanding of the present invention, the following preferred embodiments are provided in conjunction with the drawings to describe the invention in detail.

Further features of the invention and advantages thereof will be apparent from the following description, when read in conjunction with the accompanying drawings.

Detailed Description

Referring to fig. 1 to 4, an embodiment of an induction type pressurizing device of an automatic screen printing machine according to the present invention is shown, which comprises a driving motor 1, a pressurizing part 2 and a pressure induction controller 3.

The pressing portion 2 includes a squeegee or a roller (in this embodiment, a squeegee is taken as an example) for performing a printing operation while pressing down on a workpiece 4.

The pressure sensing controller 3 is connected to the driving motor 1 and the pressurizing part 2, respectively, and the pressure sensing controller 3 is used for sensing a contact pressure generated when the pressurizing part 2 applies pressure, so as to control the driving motor 1 to drive the pressurizing part 2 to lift and adjust the position in time.

Therefore, in the implementation, after the user sprays or coats the ink or other substances on the workpiece 4, when the pressing part 2 (scraper) moves the ink downwards on the workpiece 4, the pressure sensing controller 3 can sense the contact pressure reflected when the pressing part applies pressure at any time, so as to control the driving motor 1 to drive the pressing part 2 to lift and adjust the position in time, thereby achieving good printing effect and further improving the processing quality and precision.

The above detailed description is for the purpose of illustrating the possible embodiments of the present invention, but the present invention is not limited to the embodiments, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
