Abstract
The utility model discloses a filter for a copper-clad plate production process, which comprises a filter body and a filter screen arranged inside the filter body. The filter screen divides an internal space of the filter body into a filter cavity and a filter liquor containing cavity, and a metal alien object absorbing device is arranged in the filter cavity. The filter for a copper-clad plate production process not only can filter ordinary sundries in resin impregnation liquor, but also can more effectively remove metal alien objects in the impregnation liquor, is favorable for follow-up production working procedure, but also improves quality of products.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of filter that is used for the copper-clad plate production process.
Background technology
Copper-clad laminate (abbreviation copper-clad plate) is a baseplate material of making printed circuit board (PCB), and as shown in Figure 1, the production process of copper-clad plate is: at first prepare epoxy resin mixed liquor (promptly containing immersion liquid) in reactor 100; After preparing the immersion liquid that contains in the reactor 100 is contained in the immersion trough 102 through being pumped into behind the filter 101, glass fabric 103 makes its surperficial impregnation last layer resin after drying machine 104 dryings through containing immersion trough 102, the plexiglas cloth that glass fabric 103 is become have certain stiffness, by cutting machine 105 dried plexiglas cloth is cut into the backing material plate 108 of same size then, stack backing material plate 108 then and cover Copper Foil 106 (the single-layer printed circuit plate only needs one deck Copper Foil) and form copper-clad plate to be formed, put into press 107 pressurized, heated then and handle and form copper-clad plate 109.
Because resin contains immersion liquid and recycles, filter 101 of the prior art can filter out resin to a certain extent and contain foreign matter in the immersion liquid.But be arranged in the impregnation impregnation groove 102 transmit glass fabrics transfer roller (DIP ROLL, not shown among Fig. 1) may with contain immersion trough 102 unexpected frictions and produce tiny metallic foreign bodies.Existing filter 101 can not well be removed metallic foreign body, therefore influences product quality.
The utility model content
In view of the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of filter that is used for the copper-clad plate production process, and the fine removal resin of this filter energy contains the metallic foreign body in the immersion liquid.
To achieve these goals, embodiment of the present utility model provides a kind of filter that is used for the copper-clad plate production process, comprise filter body and the screen pack that is arranged at described filter body inside, described screen pack is divided into filter chamber and filtrate containing cavity with described filter body inner space, wherein, be provided with a metallic foreign body adsorbent equipment in the described filter chamber.
As preferably, described metallic foreign body adsorbent equipment is a magnet.
As preferably, described magnet is toroidal, evenly is provided with a plurality of bar magnets perpendicular to plane, described magnet annulus place on the anchor ring of described magnet.
As preferably, described magnet is arranged at the bottom of described filter chamber, and the upper surface of described magnet is provided with a plurality of bar magnets.
Compared with prior art, the filter that is used for the copper-clad plate production process of the present utility model not only can filter out resin and contain general impurity in the immersion liquid, also can remove preferably and contain metallic foreign body in the immersion liquid, help subsequent handling production, improve product quality.
Description of drawings
Fig. 1 is the production procedure schematic diagram of copper-clad laminate manufacturing process;
Fig. 2 is the cross-sectional view of the filter that is used for the copper-clad plate production process of an embodiment of the present utility model;
Fig. 3 is the perspective view of the metallic foreign body adsorbent equipment of the filter that is used for the copper-clad plate production process of an embodiment of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
As shown in Figures 2 and 3, a kind of filter that is used for the copper-clad plate production process that embodiment of the present utility model provides, comprise filter body 1 and the screen pack 2 that is arranged at described filter body 1 inside, described screen pack 2 is divided into filter chamber 13 and filtrate containing cavity 14 with described filter body 1 inner space, wherein, be provided with a metallic foreign body adsorbent equipment 3 in the described filter chamber 13.During filtration, the resin that need filter contains immersion liquid and at first enters filter chamber 13 by filter inlet 11, enters filtrate containing cavity 14 backs through filter screen 2 then and enters next process from filter outlet 12 discharges.Thereby the metallic foreign body adsorbent equipment 3 that is arranged in filter chamber 13 then can at first guarantee that with metallic foreign body absorption filtrate does not contain the metal impurities that can't be filtered net 2 filtrations before filtration.
In the copper-clad plate production process, as previously mentioned, the metallic foreign body of generation mostly is can be by the impurity of attraction, and therefore as preferred, described metallic foreign body adsorbent equipment 3 is a magnet 31.
In addition, in order to obtain better adsorption effect, as shown in Figure 3, magnet described in the present embodiment 31 is toroidal, evenly is provided with a plurality of bar magnets 32 perpendicular to plane, described magnet 31 annulus place on the anchor ring of described magnet 31.Vertically disposed a plurality of bar magnet 32 can be distributed in the described filter chamber 13 uniformly, farthest makes the resin that needs filtration contain immersion liquid and through before the screen pack 2 metallic foreign body is adsorbed.Bar magnet described in the present embodiment 32 is provided with three.
In the utility model, can imagine that upper surface or lower surface that described a plurality of bar magnets 32 are vertical at described circular ring magnet 31 can play essentially identical metallic foreign body adsorption effect.But when described bar magnet 32 is arranged at described magnet 31 lower surfaces, described bar magnet 32 may puncture screen pack 2, therefore preferably, described magnet 31 can be arranged at the bottom of described filter chamber 13, and described a plurality of bar magnet 32 is arranged at the upper surface of described magnet 31.
