Specific embodiment
In order to which those skilled in the art is made to more fully understand application scheme, below in conjunction in the embodiment of the present application The technical solution in the embodiment of the present application is clearly and completely described in attached drawing.Obviously, described embodiment is only Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those skilled in the art are not having All other embodiments obtained under the premise of creative work are made, shall fall in the protection scope of this application.
It please refers to Fig.1 to Fig.3, the mouth of a river processing jig 1 that the application first embodiment provides is (to be processed for cutting inside casing Workpiece) mouth of a river 102 on 10, inside casing 10 is the plastic parts of injection molding, and there are one can be with driving water planar horizontal for tool The datum level 11 being placed with, inside casing 10 also have there are one the side wall 12 for intersecting (such as vertical connection) with datum level 11, in general, side wall It is formed with the mouth of a river 120 on 12, the top tool of side wall 12 has the region of one section of preset length there are one end face 121 on end face 121 1210 be dispensing plane, for being bonded after dispensing with other structures.The vertical range D1 of the mouth of a river 120 to datum level 11 is less than dispensing Plane 1210 arrives the vertical range D2 of datum level 11.The mouth of a river 120 is protruded outward from side wall 12.
In the present embodiment, inside casing 10 is the mainboard upper cover or lower cover of mobile terminal, and there are one the flat lids in surface for tool Body (can be considered datum level 11) and with cover side frame (can be considered side wall 12) substantially connected vertically, the point on side wall 12 After 1210 dispensing of glue plane, it can be bonded with display module (Touch Panel, TP).In actual processing, datum level 11 It can also be the metal insert for moving towards setting along the seamed edge of cover positioned at cover.
Referring to Fig. 3, processing jig 1 includes stent 20 and cutter head 30.Stent 20 includes bottom surface 21, side 22, end face 23. Stent 20 is used to connect cutter head 30.In the present embodiment, bottom surface 21, side 22 and end face 23 intersect vertically, and crosspoint A is cube Body vertex.In other embodiments, the angle of intersection in three faces can be other number of degrees, if stent 20 can with it is to be processed The angle of the datum level 11 of workpiece and the angle of cut of side wall 12 matches so that and bottom surface 21 is used for and datum level 11 is bonded, Side 22 is used to be bonded with side wall 12.
End face 23 is the front end of entire stent 20.In use, apply thrust from the rear portion of end face 23 so that 20 edge of stent It datum level 11 and side wall 12 is pushed positioned at the cutter head cutting mouth of a river 120 of end face 23.
Cutter head 30 specifically, cutter head 30 is located at crosspoint A, and protrudes from stent 20 for cutting the mouth of a river 120.Cutter head 30 include rake face 31 and blade 32.
Rake face 31 is 30 front end surface of cutter head, and a side on the surface is sharp blade 32, and blade 32 It is vertical with bottom surface 21, when cutting the mouth of a river 120,32 adjacent sidewall 12 of blade.After cutter head 30 touches the mouth of a river 120, mainly by blade 32 It is cut.The length L of blade 32 is less than the vertical range D2 that dispensing plane 1210 arrives datum level 11, and equal to or more than water Mouthfuls 120 to datum level 11 vertical range D1.In this way, when blade 32 is due to the propulsion of stent 20, the mouth of a river 120 is just cut, but It is since length is not enough to less than D2 to touch dispensing plane 1210, it is achieved thereby that only cutting the mouth of a river but not injuring dispensing plane Purpose.
In the present embodiment, rake face 31 is parallel with end face 23.Further, cutter head 30 further includes rear knife face 33, rear knife Face 33 and intersecting with rake face 31, rear 33 adjacent sidewall 12 of knife face, blade 32 is the intersecting lens of rake face 31 and rear knife face 33.Afterwards Knife face 33 and rake face 31 can be intersected vertically, it is possible to have acute angle.In the present embodiment, rear knife face 33 and side 22 is coplanar.
Cutter head 30 and stent 20 can be integrally formed, can also detachably be connected by the modes such as buckle and stent 20 It connects.
To sum up, since the length of the blade 32 of processing jig 1 provided in this embodiment is less than dispensing plane 1210 and benchmark The spacing in face 11, when processing jig 1, which is bonded datum level 11, promotes cutting, blade 32 cuts 120 clean noresidue of the mouth of a river, and not It can cut and hinder dispensing plane 1210.
Referring to Fig. 4, the processing jig 2 that second embodiment of the invention provides further includes Handheld Division 40, Handheld Division 40 and branch Frame 20 connects, and facilitates manual operations.Stent 20 also has a rear end face 24 opposite with end face 23, after Handheld Division 40 is mounted on End face 24, and extend to the direction far from bottom surface 21, one is formed in tail portion convenient for hand-held bending part 401, it is whole convenient for promoting A processing jig 2.
Referring to Fig. 5, there are two stent 50 (the omitting Handheld Division) tools for the processing jig 3 that third embodiment of the invention provides Cube crosspoint B, that is, there are two parallel sides 52 for the tool of stent 50, and and bottom surface 51 is vertical, so as to form two cubes Intersection points B.
Accordingly, processing jig 3 sets a cutter head 53 in each cube crosspoint B, can make full use of add in this way The cube structure of tool and gauge 3, when manually operating, it is not necessary to take notice of the placement direction of processing jig 3, arbitrary side can be cut It cuts, it is easy to use.
Referring to Fig. 6, there are four the tools of stent 60 of processing jig 4 (omitting Handheld Division) that fourth embodiment of the invention provides Cube crosspoint C, that is, there are two parallel sides 62 for the tool of stent 60, and and bottom surface 61 is vertical, and also there are two parallel ends for tool Face 63, each end face 63 and adjacent bottom surface 61, adjacent 62 vertical connection of side, so as to form four cube intersection point C.
Accordingly, processing jig 4 sets a cutter head 64 in each cube crosspoint, so not only can be in operation Without paying attention to the placement direction of processing jig 4, the mouth of a river can also be cut in promoting and retracting.Jig is in push-and-pull The mouth of a river is cut repeatedly, and mouth of a river cutting can be made cleaner.
Embodiment described above only expresses the several embodiments of the application, and description is more specific and detailed, but simultaneously Cannot the limitation to the application the scope of the claims therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art For, under the premise of the application design is not departed from, various modifications and improvements can be made, these belong to the guarantor of the application Protect range.Therefore, the protection domain of the application patent should be determined by the appended claims.
