[0002] In the process of manufacturing automobile fans, locking the PCB to the semi-finished motor with screws is an important step in assembling automobile fans. To improve efficiency and save labor, manufacturers will introduce automatic screwing devices.

[0003] The automatic screwing device attracts the screw through the magnetism of the electric screwdriver, or attracts the screw through the electric screwdriver with a vacuum adsorption function. Then, after inserting the screw into the screw-locking position of the PCB, the electric screwdriver tightens the screw, thereby locking the PCB to the semi-finished motor. However, during the process of the electric screwdriver attracting the screw and moving it to the screw-locking position of the PCB, the screw attracted by the electric screwdriver has the risk of falling. If the screw falls into the semi-finished motor, it will affect the subsequent assembly of the fan. If the screw falls onto the automatic screwing device, it is likely to cause the automatic screwing device to malfunction. Summary of the Utility Model

Therefore, it should not be construed as a limitation to the present utility model.

[0022] The embodiments of the present utility model are as follows Figures 1 to 5As shown in the figure, an automobile fan PCB screwing device includes a base 1 and a carrier plate 20 carrying semi-finished motors. A conveyor line for conveying the carrier plate 20 is provided at the top of the base 1. The conveyor line is a double-speed chain conveyor line 2. The double-speed chain conveyor line 2 is located at the front side near the top of the base 1 and extends in the left-right direction. The carrier plate 20 is arranged on the double-speed chain conveyor line 2. Preferably, there are three carrier plates 20, and the three carrier plates 20 are equally spaced in the left-right direction of the double-speed chain conveyor line 2. Two semi-finished motors spaced in the left-right direction are carried on each carrier plate 20. A screwing mechanism 3 for locking the PCB on the semi-finished motor is provided on the base 1. There are also three screwing mechanisms 3, which improves the assembly efficiency. Each screwing mechanism 3 includes a three-axis moving platform 30 and an electric screwdriver 31. The three-axis moving platform 30 is arranged at the top of the base 1, and the three-axis moving platform 30 is located at the rear side of the corresponding carrier plate 20. The electric screwdriver 31 is arranged on the three-axis moving platform 30. A horizontal plate 4 and a bracket 40 supporting the horizontal plate 4 are provided on the base 1 and are located directly above the conveyor line. That is, the double-speed chain conveyor line 2 is located directly above the double-speed chain conveyor line 2. There are three horizontal plates 4, and the three horizontal plates 4 are respectively located directly above the three carrier plates 20. A positioning through hole is provided on each horizontal plate 4. A baffle 41 covering the positioning through hole is provided on the upper surface of the horizontal plate 4. A through hole for the screw to pass through is provided on the baffle 41, and the through hole communicates with the positioning through hole. A guide block 43 covering the through hole is provided on the upper surface of the baffle 41. A guide through hole 44 communicating with the through hole is provided on the guide block 43. Three lifting mechanisms 5 for lifting the three corresponding carrier plates 20 are also provided on the base 1.

[0023] After the double-speed chain conveyor line 2 moves the three carrier plates 20 to the corresponding screwing stations, the three screwing mechanisms 3 screw the PCB and the semi-finished motors on the corresponding carrier plates 20. By providing the horizontal plate 4 directly above the double-speed chain conveyor line 2, when the screw drops from the electric screwdriver 31, the horizontal plate 4 will catch the dropped screw, effectively preventing the screw from falling onto the screwing device or the semi-finished motor. The screwing mechanism 3 screws the PCB at the screwing position through the guide through hole 44, and the guide block 43 can prevent the screw on the horizontal plate 4 from falling from the through hole onto the semi-finished motor or the screwing device.

[0024] Further improvement, such as Figure 2 and Figure 3As shown in the figure, a plurality of screw through holes are arranged on the baffle 41 at equal intervals in the circumferential direction along the edge of the baffle 41. The horizontal plate 4 is provided with a plurality of corresponding first threaded holes at positions corresponding to the plurality of screw through holes. The baffle 41 is provided with a plurality of hand-tightening screws 42 passing through the corresponding screw through holes and threadedly connected to the corresponding first threaded holes.

The baffle 41 is provided with second threaded holes on both opposite sides of each through hole. Extension plates 45 covering the corresponding second threaded holes are provided on both opposite side walls of each guide block 43. Each extension plate 45 is provided with an extension plate through hole 46 coaxial with the corresponding second threaded hole. By screwing a screw through the extension plate through hole 46 and threadedly connecting it to the second threaded hole, the guide block 43 can be detachably fixed on the baffle 41, facilitating the replacement of the guide block 43. By replacing the baffle 41 and the guide block 43, screws can be driven into the PCB on semi-finished motors of different specifications.

[0025] Further improvement, as Figure 1 , Figure 2 and Figure 5 shown in the figure, the horizontal plate 4 is provided with a surrounding plate 47 along the edge to surround the top end of the horizontal plate 4, effectively preventing the dropped screws from rolling off from the edge of the top surface of the horizontal plate 4.

[0026] Further improvement, as Figure 1 and Figure 5 shown in the figure, the lifting mechanism 5 includes a top plate 50 and a cylinder 51 for driving the top plate 50 to lift and lower. The top plate 50 is located between the two guide rails of the double-speed chain conveyor line 2. A groove is provided on the top end of the base 1 between the two guide rails of the double-speed chain conveyor line 2. The base 1 is provided with a mounting plate 52 covering the groove. The cylinder 51 is arranged at the bottom end of the mounting plate 52 and is located in the groove. The output shaft of the cylinder 51 faces upward and is connected to the bottom end of the top plate 50, that is, the output shaft of the cylinder 51 passes through the top end of the mounting plate 52 and is connected to the bottom end of the top plate 50. By the lifting mechanism 5, the carrier plate 20 is lifted, so that the semi-finished motor on the carrier plate 20 is closer to the baffle 4, thus facilitating the screwing mechanism 3 to drive screws.

[0027] Further improvement, as Figure 1 and Figure 2 shown in the figure, the base 1 is provided with a photoelectric sensor 6 for detecting the position of the semi-finished motor on the conveyor line. Two photoelectric sensors 6 are provided directly below each horizontal plate 4. By the two photoelectric sensors 6 corresponding to detect the positions of the two semi-finished motors on the carrier plate 20, it is prevented that the equipment works abnormally due to the incorrect position of the semi-finished motor.

[0028] It should be understood that those of ordinary skill in the art can make improvements or modifications according to the above description, and all such improvements and modifications shall fall within the protection scope of the appended claims of this utility model.
