In order to achieve the purpose, the invention is realized by the following technical scheme:
the utility model provides a silicon chip wiper mechanism for developing machine, is including wasing cup, spray ring and unable adjustment base, the spray ring is fixed to be located wash on the cup, unable adjustment base is fixed to be located wash the bottom of cup, wash and be equipped with corresponding installation through-hole on cup, spray ring and the unable adjustment base respectively, wash cup, spray ring and unable adjustment base and locate through the screw rod respectively carry out fixed mounting in the installation through-hole, be equipped with the feed liquor hole that the several distributes evenly on wasing the lateral wall of cup, be equipped with the several spray hole that the several distributes evenly on the spray ring, the feed liquor hole with be equipped with several passageways that are used for the liquid circulation between the spray hole.
Further, the channels respectively comprise a first flow passage, a second flow passage and a third flow passage.
Further, the second flow channel comprises a first flow channel positioned in the cleaning cup body and a second flow channel positioned in the water spray ring.
Furthermore, the number of the liquid inlet holes is four.
Further, the number of the liquid spraying holes is four.
To sum up, the utility model has the advantages that: this silicon chip wiper mechanism has changed and has adopted twenty runners to supply liquid among the prior art, the utility model discloses well passageway includes first runner, second runner and third runner respectively, wherein, the second runner has included second runner one and second runner two, every hydrojet point adopts four runners totally twelve runners promptly, the reduction of runner, its processing technology is easier than original, reduce the processing cost, in addition, reduce the probability that a plurality of runner junctions blockked up or the side leakage, improve the qualification rate of work piece, long service life, still reduce the runner mouth seepage risk that needs to block up, reduce work piece scrap probability, no seepage risk, can satisfy the market demand.
