Description

Full length automatic inspection device of multi-stage series fan

The present invention relates to a full-length automatic inspection device for a multi-stage series fan, and more particularly, in the process of producing a multi-stage series fan used in a cooling device such as an air conditioner, by checking the total length of the completed fan automatically, The present invention relates to a full-length automatic inspection device for a multi-stage series fan configured to be separated and conveyed by defective determination.

In general, a long fan used in an air conditioner is injection-molded with synthetic resin, and is composed of a plurality of cells rather than being integrally manufactured in terms of product strength, vibration to noise reduction, and manufacturing convenience. As an example of such a multi-stage fan, FIG. 1 shows a multi-stage series fan P in which a plurality of cells are connected.

The multi-stage series fan P is completed by connecting the lower cell P1, the plurality of intermediate cells P2, and finally the upper plate P3 by, for example, an ultrasonic welding method. Each intermediate cell P2 has a welding plate P5 and a wing portion P6, and ends of the plurality of wings of the wing portion 6 in a plurality of welding grooves formed on the welding plate P5. Has a structure that can be inserted by a predetermined depth. Thus, the end of the blade inserted into the welding groove can be melted by ultrasonic waves and bonded to the welding plate P5. On the other hand, the rotary shaft (P4) is coupled to the lower cell (P1) and the upper plate (P3) forming both ends of the multi-stage series fan (P), respectively, when the rotary shaft (P4) is employed in, for example, a wall-mounted air conditioner. It can be connected to the drive means through.

In order to be assembled in such air conditioners, certain standard conditions must be satisfied, and once the product is completed in the welding process, the defective product must be removed through proper inspection process. Among such inspections, there is a process of inspecting the entire length of the finished product, that is, the overall length. If the overall length of the welded multi-stage series fan P is out of a certain error range, it cannot be assembled to a product such as an air conditioner, and the wing parts P6 adhere to each welding plate P5 too badly. Otherwise, it means that there is too little welding, which can be indirectly related to the lack of concentricity or straightness of the structure as a whole.

By the way, in the past, the electric field inspection of the completed multi-stage series fan P was dependent on the manual labor of the operator. That is, the operator performed a full length inspection of the multi-stage series fan (P) by using a simple measuring mechanism to determine whether there is a defect, there is a disadvantage that there is a lot of error in the measurement and it is difficult to precisely determine the defective product. As a result, there is a problem in that the productivity is lowered because the time required for work is high and the efficiency of defect removal is also lowered.

Therefore, the present invention is to solve the above-described problems, in the process of producing a multi-stage series fan employed in a cooling device such as an air conditioner, and automatically inspects the overall length of the completed fan to determine the defective and It is an object of the present invention to provide a full-length automatic inspection device for a multi-stage series fan configured to separate defective products.
