[0027] See Figure 1-7 The DC fan automatic assembly equipment shown in a preferred embodiment of the present application includes a main frame 4, an electric control cabinet, a transmission mechanism, and a fan blade assembly line. The electric control cabinet, transmission mechanism, and fan blade assembly line are arranged on the main frame 4, and the transmission mechanism and fan blade assembly line are electrically connected to the electric control cabinet. The transmission mechanism includes a fan blade conveyor belt 1, a base conveyor belt 2, a finished product output conveyor belt 3, and a tooling conveyor belt. The base conveyor belt 2, the tooling conveyor belt, and the finished product output conveyor belt 3 are arranged in sequence along the same straight line. The fan blade conveyor belt 1 is arranged parallel to the above three conveyor belts.

[0028] The tooling conveyor belt also includes a motor, a driven wheel 25 and a driving wheel 20 connected to the motor. A transmission chain 21 is provided on the outside of the driving wheel 20 and the driven wheel 25. A guide rail 22 is provided corresponding to the circumference of the outer side of the transmission chain 21. A plurality of tooling mounting blocks 23 are equidistantly provided on the transmission chain 21. The tooling mounting blocks 23 are slidably connected to the guide rail 22.

[0029] The fan conveyor belt 1, the base conveyor belt 2 and the finished product output conveyor belt 3 are all driven by belts, and the transmission operation is performed by the motors provided inside.

[0030] The fan blade assembly line from beginning to end is the base transfer station 5, stator pressing station 6, first oiling station 7, gasket assembly station 8, gasket inspection station 9, snap ring assembly station 10, snap ring inspection station 11, second oiling station 12, bearing assembly station 13, bearing pressing station 14, third oiling station 15, fan blade assembly station 16, fan blade pressing station 17, fan blade testing station 18, and finished product unloading station 19; each station is arranged equidistantly from the tooling base 24 along the axis of the tooling conveyor belt, and is electrically connected to the electrical control cabinet.

[0031] The above-mentioned workstations are all equipped with existing components such as electric cylinders, pneumatic cylinders, in-position photoelectric sensors and their combinations, which are all existing technologies and will not be described in detail here.

[0032] A fixing tool corresponding to the fan base is provided on the tool base 24 for limiting and fixing the fan base. After all workstations have completed their operations, the transmission chain 21 drives the tool base 24 to move to the next workstation, repeating the cycle.

[0034] Working principle:

[0035] The base transfer station 5 is used to transfer the fan base conveyed on the base conveyor belt 2 to the tooling base 24; the stator pressing station 6 is used to press and fix the stator on the fan base, and then the first oiling station 7 drips lubricating oil. After lubrication is completed, the gasket assembly station 8 installs the gasket on the fan base, and then the gasket inspection station 9 detects whether the gasket is missing; the snap ring assembly station 10 installs the snap ring on the fan base, and then the snap ring inspection station 11 detects whether the snap ring is missing. After the inspection is completed, the second oiling station 12 drips lubricating oil again; after lubrication is completed, the shaft The bearing assembly station 13 loads the material from the vibration disk and installs the bearing on the fan base, then presses the bearing into place at the bearing pressing station 14, and then transports it to the third oiling station 15 to add lubricating oil again; the fan blade assembly station 16 grabs the fan blades on the fan blade conveyor belt 1 and installs them on the fan base, then the fan blade pressing station 17 presses and fixes the fan blades, and performs a pulling test at the fan blade testing station 18 to check whether the fan blades are installed in place. After the test is completed, the finished product unloading station 19 finally transfers the finished product to the finished product output conveyor belt 3 for subsequent packaging and boxing.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
