Description

Technical Field

[0001] The invention belongs to the technical field of air conditioner processing, and in particular relates to an air conditioner crossflow fan blade assembly tool. Background Art

[0002] Crossflow fans, also known as crossflow fans, were first proposed by French engineer Mortier in 1892. The impeller is multi-bladed, long cylindrical, with forward multi-wing blades. When the impeller rotates, the airflow enters the blade grid from the impeller opening, passes through the inside of the impeller, and is discharged into the volute from the other blade grid to form a working airflow.

[0003] The crossflow fan blade assembly is a key component of the air conditioner indoor unit. It is mainly used to blow the (cold or hot) air near the evaporator into the room to achieve the function of cooling or heating. In order to meet the needs of the air conditioner production line operation, each component used in the air conditioner must be assembled independently as an independent unit, and then sent to the general assembly workshop to assemble the various sub-components to complete the air conditioner assembly.

[0004] The assembly of sub-components also needs to meet the requirements of production line operations. As a sub-component inside the indoor unit, the air conditioner crossflow blade assembly is used in combination with the motor assembly and is installed inside the plastic casing of the air conditioner indoor unit. The two ends of the crossflow blade assembly are the bearing assembly and the motor assembly respectively. The bearing is used to support the rotation of the crossflow blade. The rotational power of the crossflow blade comes from the motor assembly, and the motor assembly also supports the crossflow blade.

[0005] In the actual production process, the assembly of crossflow fan blades is done manually, which has low production efficiency and low assembly yield, which will affect the overall production efficiency of the air-conditioning unit. Summary of the invention

[0013] It is further configured as follows: the crossflow blade assembly includes a crossflow blade, a crossflow blade motor is arranged on one end of the crossflow blade, and a crossflow blade bearing is arranged on the other end of the crossflow blade.

[0014] It is further configured as follows: horizontal positioning plates are fixedly connected to both ends of the outer side walls of the crossflow fan motor and the crossflow fan bearing, respectively, and a latch is fixedly connected to the bottom end of any horizontal positioning plate.

[0015] It is further configured that: housing interfaces are respectively provided on both ends of the housing, and the housing interfaces are adapted to the latches on the crossflow fan motor and the crossflow fan bearing.

[0016] It is further configured as follows: the RPPR robot includes a robot base fixed on a robot bracket, an RP joint is arranged on the robot base, a P joint is arranged on the RP joint, an R joint is arranged on one side of the P joint, and front and rear jaws and left and right jaws are arranged on the bottom end of the R joint.

[0017] It is further configured as follows: the lower parts of the left and right clamping jaws are V-shaped, and the front and rear clamping jaws and the left and right clamping jaws are adapted to the crossflow fan blade assembly.

[0018] The beneficial effects of the present invention are as follows: by extending and retracting the positioning cylinder to push the side of the casing, the other side of the casing is fitted with the tooling positioning plate, which facilitates subsequent rapid assembly;

[0019] The tooling clamping plate is driven to rotate by the extension of the hydraulic cylinder, and the angle between the tooling base and the tooling clamping plate is adjusted, and then the angle between the housing and the tooling base is adjusted, thereby improving the accuracy and efficiency of automated assembly and saving production costs;

[0020] The pins on the crossflow fan motor and the crossflow fan bearing are inserted into the upper casing interfaces at both ends of the casing, so that the assembly can be completed quickly, which not only ensures the assembly accuracy but also improves the assembly yield rate.
