The following describes in detail an image sensor mark-following rotary pad printing machine according to an embodiment of the present application with reference to the drawings.
As shown in fig. 1 and 2, an embodiment of the present application provides an image sensor mark-following rotary pad printing machine, which is composed of a printing table 100, a printing screen 200, a printing device 300, a first positioning device 400, a second positioning device 500, a feeding device 600, and a conveying device 700. The printing screen 200 is fixed above the printing table 100 and is parallel to the printing table 100, and a gap of at least 2mm is formed between the printing screen 200 and the printing table 100, so that the FPC soft board 800 can pass through the gap between the printing screen 200 and the printing table 100. The FPC flexible board 800 is an FPC flexible board roll formed by connecting a plurality of rectangular printing units 810, a first positioning hole 820 is provided at the joint of the printing units 810, and second positioning holes 830 are provided at 4 end points of the printing units 810. One end of the FPC flexible board 800 is placed on the feeding device 600, and the other end is in contact with the transfer device 700, and the transfer device 700 drives the FPC flexible board 800 to move from the front end of the printing table 100 to the rear end of the printing table 100. The first positioning device 400 is located above the printing table 100, and when the first positioning hole 820 moves to the first positioning device 400, the first positioning device 400 triggers the conveying device 700 to stop operating, and the printing unit 810 stays below the printing screen 200. The first positioning means 400 activates the second positioning means 500 located below the printing screen 200, the second positioning means 500 detects the position of the second positioning hole 830, and the second positioning means 500 activates the printing means 300 when the second positioning hole 830 is present at a specified position. The printing device 300 coats solder resist ink on the printing screen 200, the solder resist ink permeates to the printing unit 810 through the hollow meshes on the printing screen 200, and after the coating is finished, the printing device 300 triggers the conveying device 700 to continue to move the FPC flexible printed board 800 until the first positioning device 400 detects the next first positioning hole 820. This embodiment completes the printing of the solder resist ink on the FPC flexible board 800 by continuously repeating the above operations. By the embodiment, the printing device 300 can start printing when the printing unit 810 is aligned with the printing screen 200, so that poor printing caused by inaccurate alignment is avoided, and the yield of products is improved.
As shown in fig. 1 and 3, another embodiment of the present application provides an image sensor mark-following rotary pad printer, and a first positioning device 400 is provided with a laser sensor 410 and a bracket 420. One end of the bracket 420 is fixed to the printing table 100, and the other end is mounted with the laser sensor 410. The support 420 is provided with a screw adjustment lever 421 which can be extended and contracted in the longitudinal direction of the printing table 100 and a link arm 422 which can be extended and contracted in the width direction of the printing table 100. The laser sensor 410 is mounted on the bracket 420, and the position of the laser sensor 410 can be adjusted according to the position of the first positioning hole 820 in actual use. The transmitting and receiving window of the laser sensor 410 is vertical to the plane of the printing table 100 and faces downwards, and when the first positioning hole 820 moves to the position below the transmitting and receiving window of the laser sensor 410, the laser sensor 410 measures the distance value between the laser sensor 410 and the printing table 100; when the first positioning hole 820 is not located below the transceiving window of the laser sensor 410, the laser sensor 410 measures a distance value between the laser sensor 410 and the FPC flexible printed circuit board 800. Since the distance between the laser sensor 410 and the FPC flexible printed circuit board 800 is smaller than the distance between the laser sensor 410 and the printing table 100, the first positioning device 400 uses the distance value between the laser sensor 410 and the printing table 100 as a reference distance, when the laser sensor 410 detects that the distance from the obstacle is equal to the reference distance, the first positioning hole 820 is located below the transceiving window of the laser sensor 410, the first positioning device 400 triggers the transmission device 700 to stop operating, and the second positioning device 500 is started. With this embodiment, the FPC flexible board 800 can be made to stay at an appropriate position, ensuring that the printing screen 200 and the printing unit 810 are aligned in the longitudinal direction of the printing table 100.

The image sensor 510 is hidden under the plane of the printing table 100, and the surface of the printing table 100 is provided with a light-transmitting hole 110 corresponding to the image sensor 510. When the printing unit 810 moves below the printing screen 200, the image sensor 510 photographs the second positioning hole 830 of the printing unit 810, and detects whether the second positioning hole 830 falls within the range of the reference position by a general algorithm. When the second positioning hole 830 falls within the reference position range, the second positioning device 500 triggers the printing device 300 to print. The present embodiment can ensure that the printing screen 200 and the printing unit 810 are aligned in the width direction of the printing table 100.
As shown in fig. 1, another embodiment of the present application provides an image sensor mark-tracking rotary pad printer, which is provided with a display 910, and the display 910 is connected to the image sensor 510.

The other end of the adsorption roller 710 is connected to a motor 750, and is driven by the motor to rotate, the adsorption roller 710 adsorbs the surface of the FPC flexible printed circuit board 800 without solder resist ink on the surface thereof by air pressure, and drives the FPC flexible printed circuit board 800 to move from the front end of the printing table 100 to the rear end of the printing table 100. Specifically, after the printing device 300 finishes smearing the solder resist ink, the suction hole 711 starts to suck the FPC flexible printed circuit board 800, the suction roller 710 rotates, and when the first positioning device 400 detects the first positioning hole 820, the suction hole 711 stops sucking air, and the suction roller 710 stops rotating.
