[0031] A method for producing a metal fan cover comprises the following steps:

[0032] S1, cutting, according to the design size, use cutting equipment to cut the aluminum alloy plate to obtain the blanks of the various components of the cover;

[0033] S2, stamping and forming, distributing each blank to its own forming equipment and forming it using the corresponding forming die;

[0034] S3, trimming and shaping: after stamping, remove the excess material on the edge of the cover parts and shape and size according to the design requirements;

[0035] S4, automatic assembly template processing, automatic assembly template processing of plastic materials by injection molding, such as Figure 1 As shown, the automatic assembly template includes a template body 1, a limiting structure 2 for limiting the assembly position of each housing accessory, and a positioning device 3 for positioning each accessory;

[0036] S5, automatic assembly, the automatic assembly template is transported to the waiting area of ​​each accessory in the assembly order of the fan casing accessories by a multi-axis manipulator, the corresponding casing accessories are fixed to the corresponding limiting structure by the positioning device on the automatic assembly template until the accessories of the entire casing are completely fixed on the automatic assembly template, and finally the multi-axis manipulator transports the automatic assembly template to the riveting machine for assembly, and the various components of the fan casing are as follows. Figure 2 As shown, it includes a housing body, baffles on both sides and a plurality of cross bars, wherein both ends of the housing body and both ends of the cross bars are provided with connecting plugs, which cooperate with the plug slots on the baffles on both sides. During assembly, the plugs of each component cooperate with the limiting structure 2 on the automatic assembly template to achieve precise positioning, and the positioning is performed by magnetic attraction, thereby achieving automatic precise assembly;

[0037] S6. Packaging: Pack the assembled fan casing together with the automatic assembly template, and then transport it to the tool storage area.

[0038] In order to ensure product quality, a surface treatment step is also included between step S3 and step S4, in which the processed cover shell accessories are anodized, and the thickness of the oxide film is controlled between 2μm and 5μm.

[0039] In order to ensure the accuracy during automatic assembly, in step S5, the waiting area of ​​the cover shell accessories is respectively provided with a detection mechanism for detecting whether the cover shell accessories are installed at the preset position of the automatic assembly template. The detection mechanism is a visual detection mechanism, which can automatically identify whether each accessory is installed in place on the automatic assembly template, thereby ensuring the assembly accuracy.

[0040] In step S5, a workpiece carrier is further provided in the waiting area of ​​the cover casing accessory, and a workpiece suction cup is rotatably provided on the workpiece carrier. When the multi-axis manipulator moves to the waiting area, a preset angle is provided between the workpiece suction cup and the workpiece carrier. Since snap-fitting is required in the fan cover casing accessory, the accessory is set at a preset angle. When the manipulator drives the accessory on the automatic assembly template to be transported to the accessory, the two accessories in an assembly relationship directly have a preset angle. Therefore, when the accessory is sucked, automatic snap-fitting assembly is achieved from a certain angle, and the degree of automation is high.

[0041] Preferably, the multi-axis manipulator is provided with a plurality of negative pressure suction cups for sucking the automatic assembly template, the limiting structure 2 includes a limiting groove and / or a limiting baffle, the positioning device 3 is a magnet fixedly arranged on the automatic assembly template, and the magnet is embedded therein after the automatic assembly template is processed, such as opening an installation groove at the corresponding position of the template, and installing the magnet into the installation groove by interference fit, and the cutting equipment is a laser cutting machine.

[0042] Further explanation is needed. Although the method mostly uses automatic assembly templates, they are made of injection molding and are made of plastic, which has low cost and is easy to process. They are packaged together with the products to ensure the strength of the products, thereby ensuring the quality. Moreover, the automatic assembly template provides a good reference for automatic assembly and provides a good fixation function for accessories, thereby completely replacing manual assembly. In addition, when the user uses it, the template can be directly taken out from the cover after assembly, which is also convenient to use.

[0043] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
