Description
Technical field
The invention belongs to flexible circuit board ink apparatus for baking technical fields, and in particular to a kind of roasting with warp rail
Case.
Background technique
In recent years, electronic product increasingly tend to miniaturization and it is lightening, be based on the trend, the structure of electronic component and its carrier
It makes and also has to further High precision and precise treatment, and this becomes the required precision to bonding IC increasingly
It is high.
The manufacturing method of flexible circuit board is usual are as follows: is passing through punching press and laminating technology and wet film or dry film etch process
Apply process of surface treatment and printing ink printing art on the line pattern of formation.It usually to be carried out at heat cure after ink printing
Reason, however, ink, in the curing process since ink can be heat-shrinked, especially when ink is epoxy ink, heat is received
It contracts even more serious, is heat-shrinked so that ink printing surface warpage inwardly.This warpage directly affects nation when subsequent bonding IC
Determine precision, yield and efficiency.
There are two types of traditional ink roasting modes: being respectively online baking and entire volume baking.Traditional online roasting mode
Are as follows: as shown in figure 3, flexible circuit board continues to transport forward under the action of driving idler wheel after printing machine carries out ink printing,
Then entering oven from oven import and carrying out baking makes ink setting, solidification, and product is constantly in and is baked in oven
While the state that transports forward, the product after coming out from the outlet of oven, which is overdrived, to be continued to transport forward until quilt after idler wheel
The standby reel that batches on winding off spindle batches in advance.However, this roasting mode without pre- warpage preventing measure will make product
Warpage is generated because of the thermal contraction of ink during baking.
Summary of the invention
Place, the present invention provide a kind of oven with warp rail in order to overcome the above-mentioned deficiencies of the prior art.
The present invention is achieved through the following technical solutions: a kind of oven with warp rail, the inside of oven are equipped with
Upper roller bracket fixing plate and bottom roller bracket fixing plate positioned opposite up and down, the downside of the upper roller bracket fixing plate
It is equipped with the upper roller bracket that several rows are arranged symmetrically along oven inlet and outlet direction, and the extension elongation of upper roller bracket is by centre
It is discharged into two sides row and is incremented by setting；The upside of the bottom roller bracket fixing plate along oven inlet and outlet direction be arranged symmetrically with
The bottom roller bracket that the upper roller bracket of upper roller bracket fixing plate matches, and the extension elongation of bottom roller bracket is by intermediate row
Setting of successively decreasing is arranged toward two sides, the whole on whole upper roller brackets and bottom roller bracket fixing plate on upper roller bracket fixing plate
Bottom roller bracket forms concave-convex fit structure；The free end end of upper roller bracket is equipped with along the direction rotation of oven inlet and outlet
Upper roller, the free end end of bottom roller bracket are equipped with the bottom roller along the direction rotation of oven inlet and outlet.
Further, the free end of the upper roller bracket is equipped with roller groove, and upper roller is fixed on upper rolling by shaft
In the roller groove of wheel support；The free end of the bottom roller bracket also is provided with roller groove, and bottom roller is fixed on down by shaft
In the roller groove of rolling wheel support.
The beneficial effects of the present invention are: after the present invention allows flexible circuit board to enter oven after ink printing, flexible circuitry
The garbage area of plate is clipped between upper roller and bottom roller, due under the action of the male-female engagement of upper roller bracket and bottom roller bracket
So that flexible circuit board is in being baked in the state of reversed warpage with dry solidification ink, internal ink stress is reduced with this
It concentrates, mitigates thermal contraction degree, achieve the effect that correct warpage.In addition, apparatus for baking of the invention is to carry out warpage correction
It is carried out during baking, carries out the correction of warpage without increasing additional process, do not cause the increase of cost.

Specific embodiment
Below according to drawings and examples, the present invention is further described.
As depicted in figs. 1 and 2, a kind of oven with warp rail, the inside of oven 3 are equipped with positioned opposite upper up and down
The downside of rolling wheel support fixed plate 6-1 and bottom roller bracket fixing plate 6-2, the upper roller bracket fixing plate 6-1 are along roasting
Case 3 imports and exports direction and is equipped with the upper roller bracket 5-1 that several rows are arranged symmetrically, and the extension elongation of upper roller bracket 5-1 is in
Between be discharged into two sides row and be incremented by setting, i.e., direction is imported and exported by oven 3 and seen, the upper roller bracket 5-1 of several rows is in middle part fovea superior
Arch arrangement；The upside of the bottom roller bracket fixing plate 6-2 has been arranged symmetrically along the inlet and outlet of oven 3 direction and upper roller
The bottom roller bracket 5-2 that the upper roller bracket 5-1 of bracket fixing plate 6-1 is matched, and the extension elongation of bottom roller bracket 5-2 by
Centre is discharged into two sides and arranges setting of successively decreasing, i.e., imports and exports direction by oven 3 and see, the bottom roller bracket 5-2 of several rows is convex in middle part
Arch arrangement；On whole upper roller bracket 5-1 and bottom roller bracket fixing plate 6-2 on upper roller bracket fixing plate 6-1
Whole bottom roller bracket 5-2 form concave-convex fit structure；The free end end of upper roller bracket 5-1 is equipped with to be passed in and out along oven 3
The free end end of the upper roller 4-1 of mouth direction rotation, bottom roller bracket 5-2, which are equipped with, imports and exports direction rotation along oven 3
Bottom roller 4-2；When in use, in the outlet side setting of the oven 3 for drawing the flexible circuitry of the movement of flexible circuit board 2
Coiled sheet takes reel 7.The setting number of rows of upper roller bracket 5-1 and bottom roller bracket 5-2 is true according to the arrangement number of flexible circuit board 2
Fixed, when flexible circuit board 2 arranges two rows, flexible circuit board 2 has garbage area at two sides and middle part three, at this point, upper roller branch
Frame 5-1 and bottom roller bracket 5-2 is provided with three rows, the idler wheel combination and flexible circuit board that upper roller 4-1 and bottom roller 4-2 are constituted
2 corresponding garbage area contacts, and the effective coverage of flexible circuit board 2 then corresponds to upper roller bracket fixing plate 6-1 and bottom roller branch
