The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:

as shown in Figure 1, be a kind of serigraphy automatic contraposition device of the utility model, comprise fixed head 1 and tool base plate 2, fixed head 1 and tool base plate 2 all are square, and its vertex angle part both up and down respectively is corresponding, the limit that is to say fixed head 1 and tool base plate correspondence Shang Xia 2 is parallel to each other, four the first motors 6 are installed on fixed head 1, the body part of these four the first motors 6 is fixedly connected on respectively on four limits of fixed head 1, and the bearing of trend of the pivot center of its rotating shaft is parallel with the limit of corresponding fixed head 1, all synchronously be connected with the first screw mandrel 61 in the rotating shaft of each the first motor 6, on the first screw mandrel 61, coupling is socketed with the first feed screw nut 62, the first feed screw nut 62 connects by a connecting seat 7 vertex angle part corresponding with tool base plate 2 respectively, when the first motor 6 drives the first screw mandrel 61 rotation, drive the first feed screw nut 62 along the corresponding sides activity of fixed head 1, namely driven the corresponding end bight activity of tool base plate 2 by Connection Block 7.On the relative limit that is around in fixed head 1 of the driving mechanism head and the tail that the first above-mentioned motor 6, the first screw mandrel 61, the first feed screw nut 62 form.

the lower surface of fixed head 1 also is equipped with the second motor 5, synchronously be connected with the second screw mandrel 51 in the rotating shaft of the second motor 5, on the second screw mandrel 51, coupling is socketed with the second feed screw nut 52, the fixing CCD lens assembly 4 that is equipped with on the second feed screw nut 52, one light-passing board 3 is installed on tool base plate 2, have on light-passing board 3 for the fixing vacuum absorption device of stock 8, the light incident end of the upper end of CCD lens assembly 4 passes the below that hole default on fixed head 1 is positioned at light-passing board 3, so that can seeing through light-passing board 3 from the top down, light is injected in CCD lens assembly 4.

Referring to Fig. 2, be fixed with the bearing of trend sliding rail consistent with the bearing of trend of the second screw mandrel 51 53 on the body of the second motor 5, what CCD lens assembly 4 slided is arranged on this sliding rail 53.

When changing half tone, CCD lens assembly 4 aligns by the half tone of light-passing board 3 with position to be printed, top, the four edges of CCD lens assembly 4 automatic capturing half tone screen printing pattern housings, but screen printing apparatus moves to print range, CCD lens assembly 4 detects half tone pattern frame, and the half tone contraposition is completed.In mobile half tone process, start the first motor 6, when starting two relative the first motors 6, can realize tool base plate 2 translation in the horizontal direction, if in the time of need to realizing angular alignment, four the first motors 6 start simultaneously, drive tool base plate 2 and turn over certain angle.Simultaneously, can also pass through the second motor 5, the position of mobile CCD lens assembly 4 makes CCD lens assembly 4 can catch target cross on the half tone film, and contraposition is more simple, easy row thereby make.When contraposition stock 8, product is transported on light-passing board 3, vacuum absorption device on light-passing board 3 is fixing with stock 8, at this moment, CCD lens assembly 4 detects the position of stock 8, according to the result that detects, drive tool base plate 2 translations in the horizontal direction or turn an angle, until detecting stock 8, CCD lens assembly 4 only is aligned to half tone pattern frame.

Those skilled in the art can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
