METHOD FOR MANUFACTURING LIQUID EJECTION HEAD

摘要

The present invention relates the method of manufacturing a liquid discharge head, in which a plurality of element substrates are adjacently arranged in a predetermined direction on a support plate by using a UV adhesive. The method for manufacturing a liquid ejection head is capable of reducing variations in the positions of element substrates while avoiding an increase of a tact time.

主权项

1. A method for manufacturing a liquid ejection head, in which a plurality of element substrates that eject a liquid are adjacently arranged in a predetermined direction on a support member by using an adhesive that cures by the irradiation of light, the manufacturing method comprising:
a first application step of applying the adhesive to a plurality of first areas on the support member in which element substrates that are not adjacent to each other among the plurality of element substrates are to be arranged; a first joining step of carrying out the irradiation of light and the joining of the element substrates for each of the first areas to which the adhesive has been applied in the first application step; a second application step of applying the adhesive to a plurality of second areas in which the element substrates have not been joined in the first joining step among the plurality of areas on the support member in which the plurality of element substrates are to be arranged; and a second joining step of carrying out the irradiation of light and the joining of the element substrates for each of the second areas to which the adhesive has been applied in the second application step.
