Description

Technical Field

[0001] The present invention relates to the field of crossflow fan blade production, and in particular to automated production equipment for crossflow fan blade end covers. Background Art

[0002] The fabric on the end cap is often widely used at the end of the finished crossflow fan blade. The fabric is generally positioned as an embedded part in the injection mold and injection-molded into the fan blade end cap product. The fabric mainly plays a role in assembling, positioning and fixing the finished crossflow fan blade. Crossflow fan end cap products are divided into internal repair and external repair products. The difference between internal repair and external repair is that the fabric faces the opposite direction. The internal repair products require through holes for positioning. After injection molding, the crossflow fan end cap products are cooled, shaped, and discharged for collection and blanking. The common production method for crossflow fan end caps is to manually place the fabric into the mold one by one for positioning or to use complex mechanical equipment (usually using a swing arm suction cup to achieve the opposite direction of the fabric) to externally position the fabric and then use a robot to input it into the mold for injection molding production. The working environment for personnel is harsh and safety is not guaranteed, and production efficiency is low. The complex positioning machinery and equipment lead to a high failure rate and high production and maintenance costs.

[0003] Therefore, further improvements are necessary. Summary of the Invention

The escapement method can make the arranged cloth staggered laterally to achieve separation, solving the problem of cloth stacking and overlapping. The outer diameter of the cloth searches for the M hole position in a non-contact manner, which will not wear the surface and can protect the product. From the separation and flipping of the cloth to the positioning of the shaft hole, only the up and down reciprocating action of an up and down reciprocating drive group is adopted, which greatly reduces the difficulty of electrical control and meets different production needs. The overall layout of this production equipment is simple and practical, with a low failure rate, low cost, and saves production space. BRIEF DESCRIPTION OF THE DRAWINGS
