Abstract
The invention relates to a diaphragm forming method. A diaphragm is formed in a forming cavity; the forming cavity is a geometric body with an opening, and includes a bottom wall and side walls positioned at the periphery of the bottom wall; the adjacent side walls, and the side walls and the bottom wall are perpendicular to each other; and welding surfaces are formed around one side of the opening. The forming method comprises the steps of: a step of fixedly welding the diaphragm on the welding surfaces, and a step of blowing one side of the diaphragm by hot air currents and meanwhile, sucking negative pressure on the other side of the diaphragm. In addition, the invention further provides equipment using the method for forming the diaphragm. The diaphragm forming method and equipment adopt a hot air current blowing mode not a traditional hot welding head heating mode, so that the external force effect from a hot welding head is not generated in the diaphragm forming process, the nonuniform diaphragm stretching phenomenon cannot be generated, and the diaphragm breakage probability is largely reduced.

In imaging device.
It is that pressure change is produced in fluid cartridge, existing mode is the forming cavity that an opening is arranged in fluid cartridge,
And the diaphragm after a stretching is welded in forming cavity, and fluid cartridge surface is additionally provided with a ventilation connected with forming cavity
Hole.After fluid cartridge loads imaging device, the blowning installation in equipment is connected with passage, and during work, equipment passes through passage
Blow into forming cavity, the diaphragm after the stretching deforms under airflow function, so that the pressure in fluid cartridge produces change
Change, the liquid in fluid cartridge is squeezed in imaging device.
Forming process of the diaphragm on forming cavity be：First diaphragm is welded in the surrounding of forming cavity opening, then profit
With hot weld head to stretching film during forming cavity internal motion, diaphragm deforms after being heated, and is molded under the induced effect of hot weld head
On the inwall of forming cavity.
General, the hot weld head is cuboid, when hot weld head and film contact, the actual front end face for hot weld head
Four sides and four angles, and the mid portion of hot weld head front end face does not have and film contact, thus, when hot weld head is to shaping
During the internal motion of chamber, the force part of the diaphragm is only four sides and four angles contacted with hot weld head, the diaphragm after shaping
It is mutually vertical between bottom surface and side and side and side, that is to say, that the now diaphragm area relative with hot weld head front end face
Domain is not in contact with, and when the other parts stress deformation of diaphragm, the diaphragm with hot weld head front end face opposed area does not have
Deformation, thus will cause diaphragm stretching uneven, once diaphragm is subject to slight external force effect to rupture, so as to cause diaphragm
Leakage problem.
The content of the invention
The present invention provides one kind can cause diaphragm to stretch uniform forming method and equipment.Using technical scheme be：
A kind of diaphragm forming method, the diaphragm is molded in forming cavity, and the forming cavity is the geometry with opening
