Description

A kind of release equipment

Technical field

The present invention relates to a kind of release equipment, make the not anti-release equipment be bonded on runner plate of foreign matter after especially relating to the cleaning of a kind of pressing runner plate, belong to printed wiring board technical field.

Background technology

The PCB development work of China starts from 1956,1963-1978, progressively expands and forms PCB industry.Latter more than 20 year of reform and opening-up, due to Importing Foreign Advanced Technology and equipment, single sided board, double sided board and multi-layer sheet all obtain fast development, and domestic PC B industry is ascending progressively to grow up.China due to downstream industry concentrate, labour and cost of land relatively low, become the region that growth momentum is the most powerful.Within 2002, become the third-largest PCB output state.The PCB output values in 2003 and import-export volume, all more than 6,000,000,000 dollars, surmount the U.S. for the first time, become second-biggest-in-the-world PCB output state, the ratio of the output value also by 2000 8.54% rise to 15.30%, improve nearly 1 times.Within 2006, China replaces Japan, becomes the maximum PCB production base of the global output value and the most active country of technical development.China PCB industry remains the rapid growth of about 20% in recent years, far away higher than the growth rate of World PCB industry.

The effect of runner plate is the every sandwich circuit board in isolation pressing, and enable pressing disposable pressure multilayer plank, its enough hardness and certain roughness make the wiring board energy surfacing after pressing.Pressing stack as shown in Figure 1.

Because the pcb board before pressing has PP(prepreg), drop on steel plate so inevitably have micelle, after pressing, glue will remain on runner plate, is difficult to remove.Simultaneously because bonding processes is HTHP, if steel plate falls other foreign matters upper, also can remain on steel plate after pressing.If these micelles on runner plate or foreign matter are removed not fall, because plank contacts with runner plate, plank necessarily has depression, and plank can be caused like this to scrap.Therefore runner plate before the use all will through grinding and cleaning, and object will ensure that runner plate is clean, without any foreign matter exactly.

At present, the flow process of PCB pressing station runner plate cleaning line is: brushing, washing and oven dry.Owing to remaining in the foreign matters such as cull on steel plate and steel plate adhesive force is strong especially, after brushing, (being all generally adhesive-bonded fabric brush) is difficult to thoroughly brush off, and always has foreign matter to remain on steel plate, so some producers can increase the flow process of hand sand runner plate before brushing.This needs 2 people's manpowers in left and right polishing (general runner plate is of a size of 45inch*51inch), and even so still have a lot of foreign matter to remain on steel plate, the plank after such pressing corresponding to steel plate foreign matter residual region just creates depression.Even runner plate itself also produces depression, and the runner plate of depression must be scrapped, otherwise its plank extruded just has projection, also can scrap.And its steel plate is after repeatedly polishing, thickness is thinning very soon, and thickness evenness also can be deteriorated, and this is deteriorated causing the hardness of runner plate, and the plank produced has the phenomenons such as pressing uneven thickness and gauffer, and therefore the life-span of steel plate also can reduce.

In brief, with current cleaning steel plate processing method, following shortcoming is had: the foreign matters such as the cull 1, on steel plate cannot thoroughly be removed, and can cause the shortcoming that PCB caves in.2, as used artificial hand sand, the cost of waste of manpower and milling tools.3, reduce the runner plate life-span, severe patient causes runner plate also has depression, directly causes runner plate to be scrapped.

Existing a kind of liquid medicine is named as mould release, if be coated on runner plate and can play release effect, this mould release is coated on runner plate specifically, after drying, any cull foreign matter etc. can become very weak with the adhesion of steel plate, only just can remove by brushing gently.Problem above like this can solve, but how to be coated on runner plate that this is still a difficult problem, and current industry is the good method of neither one also.Have producer to be directly fitted in rinse bath by liquid medicine, such mould release consumption is very large, and mould release is too expensive, obviously loses more than gain.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point, the equipment of a kind of coating release agent on runner plate is provided, provide a kind of simple and save the design of mould release.

According to technical scheme provided by the invention, a kind of release equipment, comprises motor, and motor and the first main shaft are to being connected, and the 3rd main shaft arranges the second delivery wheel to one end right with the second main shaft, and the second main shaft arranges the first drive to one end right with the first main shaft; First main shaft on be provided with a pair first sponge rollers, the second main shaft on be provided with a pair second sponge rollers, the 3rd main shaft on be provided with a pair the 3rd sponge rollers;

Described second main shaft holds drain cap to being provided with one with the 3rd main shaft to below; Nozzle is provided with above second sponge roller and the 3rd sponge roller.Described first main shaft is all fixed on sidewall by spacer pin two ends with the 3rd main shaft, the second main shaft.

Every a pair sponge roller of the first sponge roller, the second sponge roller and the 3rd sponge roller is divided into upper roller and bottom roller.

Tool of the present invention has the following advantages: structure of the present invention is simple and convenient, does not waste mould release.

Embodiment

As shown in Fig. 1 ~ Fig. 4, a kind of release equipment, comprises motor 1, and motor 1 is connected to 2 with the first main shaft, the 3rd main shaft to 4 and second main shaft to 3 one end arrange the second delivery wheel 5, second main shaft to 3 and first main shaft to 2 one end the first drive 6 is set; First main shaft is provided with a pair the 3rd sponge rollers 9 to being provided with a pair second sponge roller the 8, three main shafts on 3 to being provided with a pair first sponge roller 7, second main shafts on 2 on 4;

Described second main shaft to 3 and the 3rd main shaft hold drain cap 10 to being provided with one below 4; Nozzle 11 is provided with above second sponge roller 7 and the 3rd sponge roller 8.Described first main shaft to the 2, second main shaft to 3 and the 3rd main shaft 4 two ends are all fixed on sidewall 12 by spacer pin 13.

Every a pair sponge roller that first sponge rolls the 7, second sponge roller 8 and the 3rd sponge roller 9 is divided into upper roller and bottom roller.

The effect of the first sponge roller 7 siphons away the water on the runner plate after brushing, follow-up mould release is not diluted, 3rd sponge roller 9 effect sprays mould release on sponge roller, mould release is coated on runner plate by sponge roller transmission extruding by mould release, and the effect of the second sponge roller 8 stops mould release to trickle on the first sea roller 7.Namely next process dries, and is dried by the mould release be coated on runner plate.

As shown in Figure 4, on second sponge roller 8, the 3rd sponge roller 9, design sprays together respectively, the effect of the nozzle 11 on the second sponge roller 8 uses at the water-absorbing sponge roller post-foaming that dries up, the effect of the 3rd sponge roller 9 top nozzle 11 is to provide the mould release be coated on runner plate, the angle of spray must design in the inner side of spray sponge roller, so can ensure that runner plate can not leave obvious water mark after the 3rd group of sponge is rolled, guarantee to dry in follow-up baking operation.The drain cap 10 that holds in Fig. 4 is used to provide bottom roller mould release, and bottom roller, through transmission, draws the mould release held in drain cap 10, is coated on steel plate by mould release by upper bottom roller extruding.

Spraying mechanism is designed to internal circulation system, designs a 20L mould release major trough, is drawn up be sprayed onto on sponge roller by suction pump, because uninterrupted needs to control, so increase a valve after suction pump, steel plate needs absolute cleanliness, therefore before spray, increases by one filter.Drawing up through suction pump the mould release come enters in interpolation box, the mould release added in box enters nozzle by pipeline, these mould releases are except being used for except coating runner plate, also having to flow to greatly holds in drain cap, flow in mould release major trough through holding drain cap, this just constitutes a circulatory system, there is not the problem of mould release waste.
