Accompanying drawing explanation
Fig. 1 is longitudinal cross-sectional schematic of the print head of a kind of automatic pressure regulation that the utility model embodiment provides.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, for a preferred embodiment of the present utility model, a print head for automatic pressure regulation, comprises motor 1, screw rod 2, screw slide assembly 3, scraper 4, slip holder 5, shell fragment holder 6, the control module (not shown) that elastically-deformable shell fragment 7, pressure sensor 8, elastic component 9 and the signal by pressure sensor 8 control revolution can occur.
Screw rod 2 and motor 1 are in transmission connection, and screw slide assembly 3 and screw rod 2 are in transmission connection, and screw slide assembly 3 comprises nut 31, and nut 31 is threaded with screw rod 2.When motor 1 rotates, screw rod 2 while rotation by its external screw thread and nut 31 internal thread (in actual applications, also can save nut 31, on screw slide assembly 3, directly offer the internal thread mated with screw rod 2 external screw thread) coordinate and drive the upper and lower motion of screw slide assembly 3.
Scraper 4 is arranged on the bottom of screw slide assembly 3, along with steel mesh 200 is left or compresses in the upper and lower motion of screw slide assembly 3.The upper end of screw rod 2 is connected with slip holder 5 by clutch shaft bearing 10, thus screw rod 2 when rotated, slip holder 5 can't be followed it and be rotated, but when screw rod 2 is subject to active force upwards, slip holder 5 but can be subject to identical active force, thus the force transmission that screw rod 2 can be subject to by slip holder 5 is to shell fragment holder 6.Certainly; the utility model does not limit with the parts of bearing 9 as transmitting forces; as long as screw rod 2 can be ensured when rotated; slip holder 5 can not be followed it and be rotated; and when screw rod 2 is subject to active force upwards, slip holder 5 but can be subject to the part of identical active force or structure all in protection domain of the present utility model.Slip holder 5 is fixedly connected with shell fragment holder 6, one side of shell fragment 7 is fixedly connected with shell fragment holder 6, another side is fixed on fixing object, the bottom of elastic component 9 is connected on shell fragment holder 6, its top is connected with pressure sensor 8, and pressure sensor 8 is fixed on fixing object.In the present embodiment, elastic component 9 is spring.
After steel mesh 200 supported by above-mentioned scraper 4, steel mesh 200 pairs of scrapers 4, screw slide assembly 3 produces active force upwards, the slip holder 5 of annexation is had with screw slide assembly 3, shell fragment holder 6, shell fragment 7 is all subject to active force upwards, after shell fragment 7 is subject to active force upwards, upwards be out of shape, therefore shell fragment holder 6 moves up, spring-compressed, support the pressure sensor 8 on it, the pressure signal that pressure sensor 8 is subject to is transferred in control module, after its signal received of control module process, control motor 1 to rotate, screw rod 2 is made to move up or down corresponding distance, thus automatically regulate scraper 4 to support the pressure size of steel mesh 200, achieve the closed-loop control of squeegee pressure, improve printing quality and stability.
Above-mentioned print head also comprises belt 11, and motor 1 drives screw rod 2 to rotate by belt 11.Certainly, the transmission that shaft coupling realizes between motor 1 and screw rod 2 can also be used.
Have slide assemblies 51 between slip holder 5 and screw slide assembly 3, slip holder 5 vertically can be slided along screw slide assembly 3 by slide assemblies 51.Slide assemblies 51 is the structure of guide rail and the mutual buckle of sliding shoe or the structure of groove and the mutual buckle of sliding shoe.By the spacing of slide assemblies 51 and guiding, strengthen the stability of slip holder 5 in upper and lower motion process.Slip holder 5 is connected with shell fragment holder 6 by a screw 12, and the inner ring that above-mentioned print head also comprises the second bearing 20, second bearing 20 is set on the outer peripheral edge of screw 12, and the outer ring of the second bearing 20 is fixedly connected with shell fragment holder 6.Shell fragment holder 6 can be swung relative to slip holder 5 (can relatively whole scraper head assembly 30) adaptively by the second bearing 20.。
