Furthermore, the fixing part comprises a base and a cover plate, the base is square, two ends of the base are fixedly connected with base plate positioning holes at two ends of the base plate through base plate positioning needles, four corners of the cover plate are fixedly connected with cover plate positioning holes at four corners of the base through cover plate positioning needles, and the jig and the center of the cover plate are fixed into a whole.

Furthermore, the outer frame is provided with a track on the side periphery, two ends of the alignment rib are fixed with the track through screws, and the alignment rib is manually adjusted.

Furthermore, the alignment rib is in a grid shape, and the length of the alignment rib can cover a plurality of chip spaces on the substrate corresponding to the alignment rib.

Furthermore, two ends of the base are provided with arc openings.

The beneficial effects of the utility model are that, print the counterpoint tool through adjustable and can realize that multiple not unidimensional product corresponds one set of printing counterpoint tool, reduce the preparation and the administrative cost of printing the counterpoint, to new size product, need not wait for the preparation time of new tool, can not influence the production time, the cost is few, and is practical reliable.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1-3, an adjustable printing alignment jig 3 in this embodiment is used to fix a substrate 1, the substrate 1 includes a plurality of sizes corresponding to a plurality of chips 2 on each substrate 1, the substrate 1 is further provided with a screen printing jig 3, the jig 3 includes an outer frame 4 and an alignment rib 5, two ends of the alignment rib 5 are adjustably disposed on the outer frame 4, the alignment rib 5 includes a plurality of bars and the spacing corresponds to the spacing of the chips 2 on each substrate 1, and the substrate 1 is fixed to the jig 3 through a fixing member 6.

As shown in fig. 2 and 3, the outer frame 4 is provided with a rail 13 at the side periphery, two ends of the alignment rib 5 are fixed with the rail 13 through screws 14, the alignment rib 5 is manually adjusted, the alignment rib 5 is in a grid shape, and the length of the alignment rib 5 can cover the space between the plurality of chips 2 on the corresponding substrate 1.

Different from the fixed latticed tool 3 of conventionality, in this scheme, counterpoint muscle 5 can realize artificial manual regulation in the side circumference track 13 of 3 frames 4 of tool, in order to counterpoint the interval of

muscle

5 and 2 intervals of chip on the base plate 1 correspond, make things convenient for follow-up silk screen, realize printing position measurement, the location after the regulation is passed through screw 14 and will be counterpointed 5 both ends of muscle and track 13 groove and fix, during the actual operation, can go to increase and decrease 5 quantities of counterpoint muscle according to 2 sizes of corresponding chip on the different base plates 1, finally realize adjustable, be simultaneously tool 3 for latticed silk screen printing, for saving the cost, this scheme chooses the mode that hand modulation combines screw 14 to fix for use, actually can include multiple regulation mode, do not regard this as the limitation.
