Description

A kind of release equipment

Technical field

The utility model relates to a kind of release equipment, especially relates to making the not anti-release equipment that is bonded on the runner plate of foreign matter after a kind of pressing runner plate cleans, and belongs to the printed wiring board technical field.

Background technology

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

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

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

At present, the flow process of PCB pressing station runner plate cleaning line is: brushing, washing and oven dry.Because it is strong especially with steel plate adhesive force to remain in the foreign matter such as cull on the steel plate, thoroughly brushes off through (generally all being the adhesive-bonded fabric brush) is very difficult after the brushing, always has foreign matter to remain on the steel plate, so some producers can increase the flow process of hand sand runner plate before brushing.This need 2 people's manpowers about polishing (general runner plate is of a size of 45inch*51inch), even so still have a lot of foreign matters to remain on the steel plate, just produced depression at the corresponding plank of steel plate foreign matter residual region after the pressing like this.Even runner plate itself also produces depression, and the runner plate of depression must be scrapped, otherwise the plank of its extrusion just has projection, also can scrap.And its steel plate is through after the polishing repeatedly, the very fast attenuation of thickness, and thickness evenness also can variation, and this will cause the hardness variation of runner plate, and the plank of producing has the phenomenons such as pressing uneven thickness and gauffer, so the life-span of steel plate also can reduce.

In brief, the cleaning steel plate processing method with present has following shortcoming: 1, the foreign matters such as cull on the steel plate can't thoroughly be removed, and can cause the shortcoming of PCB depression.2, as using 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 depression, directly causes runner plate to be scrapped.

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

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, and the equipment of a kind of coating release agent on runner plate is provided, and a kind of simple and design of saving mould release is provided.

According to the technical scheme that the utility model provides, a kind of release equipment comprises motor, and motor and the first main shaft are to linking to each other, and the 3rd main shaft is to arranging the second delivery wheel with the right end of the second main shaft, and the second main shaft is to arranging the first drive with the right end of the first main shaft; The first main shaft on be provided with a pair of the first sponge roller, the second main shaft on be provided with a pair of the second sponge roller, the 3rd main shaft on be provided with a pair of the 3rd sponge roller;

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

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

The utlity model has following advantage: the utility model convenience simple in structure, do not waste mould release.
