Description
Technical field
The present invention relates to the manufacture method of the composite molded product of being made by metal forming body and resin molded body.
Background technology
Consider from the light-weighted viewpoint of various parts, using resin molded body as metal substitute product, but be many times difficult to substitute all metallic elements with resin.In this case, it is generally acknowledged, by metal forming body and resin molded body are engaged to the integrated new composite part of manufacturing.
But, by metal forming body and resin molded body with industrial favourable method and can engage integrated technology with high bond strength also cannot practical application.
In No. 4020957 communique of patent, record a kind of invention of the laser processing for the metal surface that engages with different types of material (resin), the method comprises: to metal surface, and the operation of carrying out laser scanning along a scanning direction; With the operation of carrying out laser scanning along the scanning direction intersecting therewith.
In JP 2010-167475 communique, in No. 4020957 communique of patent, a kind of invention of laser processing is also disclosed, the method is repeatedly carried out laser scanning overlappingly.
But the invention of No. 4020957 communique of patent, JP 2010-167475 communique must be carried out laser scanning to the both direction intersecting, and therefore, spent long side have room for improvement in process time.
Moreover, can carry out sufficient rough surface processing by the laser scanning to crisscross, therefore, think that bond strength can improve, but have likely likely unstable and so on the problem of directionality of the intensity of the bonding part of inhomogeneous, metal and resin of surface roughness state.
In addition, be complicated shape or for example contain, the thin shape partly of width (star, triangle, dumbbell shape) on composition surface, think along in crisscross method of carrying out laser scanning, occur that the coarse processing of local surfaces is inhomogeneous, result can not get sufficient bond strength.
In Unexamined Patent 10-294024 communique, recorded form to metal watch surface irradiation laser concavo-convex, in the manufacture method of the electric and electronic parts such as concavo-convex forming part injection-molded resin, rubber.
In embodiment 1～3, record to the rectangular coil surface of metal and carried out Ear Mucosa Treated by He Ne Laser Irradiation and form concavo-convex technology.And, in paragraph 10, recorded the situation that rectangular metal coil surface is damaged to striated or pears skin shape, in paragraph 19, recorded by rectangular metal coil surface be damaged to striated, select wire, wave-like line, knurling, pears skin shape.
But as described in the invention effect of paragraph 21,22, the object of carrying out Ear Mucosa Treated by He Ne Laser Irradiation is fine and irregular concavo-convex in order to form in metal surface, improves thus anchoring effect.Especially because handling object is the rectangular coil of metal, so no matter think what kind of having formed concavo-convex in the situation that, must be fine and irregular concavo-convex.
Thus, the disclosure of the invention of Unexamined Patent 10-294024 communique with as the invention of No. 4020957 communique of patent, JP 2010-167475 communique, carry out Ear Mucosa Treated by He Ne Laser Irradiation and form the fine identical technological thought of concavo-convex invention on surface along crisscross.
