[0001] The present application relates to the technical field of ceiling fans, and in particular to a square ceiling fan assembly production line. Background Art

[0002] At present, a ceiling fan is a fan usually installed on the ceiling. Because it adopts a hanging structure, it is called a ceiling fan. The ceiling fan is usually fixed to the ceiling by a hanging plate 31, such as Figure 10 As shown, the structure of a related hanging plate 31 is composed of a main body 31, a hanging ball 32, a fixing frame 33 and a rubber pad 34. The main body 31 and the hanging ball 32 need to be riveted together first, and the fixing frame 33 needs to be fixed to the main body 31 with screws, and then the rubber pad 34 needs to be fixed to the main body 31. The hanging plate also needs to be labeled, assembled with a ground wire and bagged before it can be sold.

[0003] During the assembly process, the hanging tray is assembled in sequence from various components, which requires the cooperation of multiple workstations. However, if there are too many people involved in the assembly process, not only will the assembly efficiency be low, it will also easily cause errors and omissions, and the yield rate of the finished hanging tray will be low, which cannot meet the needs of development. This situation needs to be improved. Summary of the Invention

[0004] In order to improve the yield rate of finished hanging trays, the present application provides a square hanging tray assembly production line.

The transmission line transports the hanging tray to each of the workstations along a predetermined trajectory. The multiple workstations include a locking station, a labeling station, a rubber pad assembly station, a ground wire assembly station and a packaging station arranged in sequence along the predetermined trajectory. The locking station is used to lock the screws between the fixed frame and the hanging tray, the labeling station is used to attach labels to the fixed frame and / or the hanging ball, the rubber pad assembly station is used to fix the rubber pad on the hanging tray, the ground wire assembly station is used to fix the ground wire on the hanging tray, and the packaging station is used to package the finished hanging tray and then unload it; the transmission line also includes a conveying mechanism arranged between two adjacent workstations and used to transfer the hanging tray.

[0007] By adopting the above technical solution, after the hanging ball is riveted onto the hanging tray, the fixing frame is placed on the hanging tray, and then the hanging tray is transferred to the locking station. After the fixing frame is locked with the hanging tray by screws, the hanging tray is transferred to the labeling station through the transmission mechanism. After the label is attached to the fixing frame and / or the hanging ball, the hanging tray is transferred to the rubber pad assembly station through the transmission mechanism, the rubber pad is assembled on the hanging tray, and then transferred to the ground wire assembly station through the transmission mechanism. After the ground wire is assembled on the hanging tray, the hanging tray assembly is completed and the hanging tray is transferred to the packaging station for packaging. The solution in this application integrates multiple stations in the hanging tray assembly process into a transmission line, so that the hanging tray completes the assembly of each component in sequence along a predetermined trajectory, thereby improving the degree of automation of the hanging tray assembly, improving assembly efficiency, reducing the probability of errors and omissions, and thus improving the yield rate of the finished hanging tray product.

[0008] Optionally, the conveying mechanism includes a first robot arranged at the locking station and used to transfer the hanging tray from the locking station to the labeling station, a second robot arranged at the rubber pad assembly station and used to transfer the hanging tray from the labeling station to the rubber pad assembly station, and a third robot arranged at the ground wire assembly station and used to transfer the hanging tray from the rubber pad assembly station to the ground wire assembly station, wherein the third robot is provided with a visual detector for detecting the hanging tray.

[0009] By adopting the above technical solution, a visual detector is installed on the third manipulator. After the hanging tray completes the assembly processes such as screw locking, labeling, and rubber pad assembly, the transfer and detection functions of the third manipulator can be used to plan a defective product placement area between the rubber pad assembly station and the ground wire assembly station. If the hanging tray is found to be unqualified after inspection, it will be placed in the defective product placement area. If it is qualified, it will be transferred to the ground wire assembly station through the third manipulator. The visual detector is used to perform a first round of inspection before the hanging tray is packaged, thereby improving the qualified rate of the hanging tray. Moreover, it can be detected during the transportation of the third manipulator, thereby improving the efficiency of detection.

[0010] Optionally, the locking station is provided with an electric screw assembly for screwing screws into each locking position between the fixing frame and the hanging tray. After the screws between the fixing frame and the hanging tray are locked, the hanging tray is transferred to the labeling station by the first manipulator.

[0011] By adopting the above technical solution, the screws fix the fixing frame to the hanging plate through the electric screwdriver assembly, which can improve the locking quality and locking efficiency. Multiple electric screwdriver assemblies can also be installed according to the position to be locked, thereby improving the efficiency of the hanging plate assembly process.

The label moving mechanism moves the label suction robot to the fixed frame and / or the hanging ball to be labeled.

[0013] By adopting the above technical solution, the hanging tray is transported to the labeling position by the fixed-distance translation frame. Since the fixed frame and the hanging ball on the hanging tray have multiple positions to be labeled, the automatic label changing mechanism, the label suction robot and the label moving mechanism serve as labeling components to attach the labels to the fixed frame and / or the hanging ball. Multiple labeling components can be set on both sides of the fixed-distance translation frame, and then the hanging tray is transported to the labeling position at a fixed point by the fixed-distance translation frame, thereby improving the efficiency of the hanging tray in the labeling process.

[0014] Optionally, the label suction robot includes a label suction component for picking up labels and a lifting drive component for driving the label suction component to move vertically.

[0015] By adopting the above technical solution, after the label suction robot absorbs the label through the label suction component, it moves the label away from the platform where the label is placed through the lifting drive component, and then moves the label to the hanging plate through the label moving mechanism. The cooperation between the label suction component and the lifting drive component can conveniently realize the picking up of the label from the automatic label changing mechanism.

After the rubber pad is transferred to the bottom of the hanging plate, the hanging plate is provided with an installation hole for the rubber pad to be embedded, and then the rubber pad is embedded in the installation hole through the lifting mechanism, so that the rubber pad is installed on the hanging plate.

[0018] Optionally, the ground wire assembly station includes a conveyor belt for transporting a hanging tray. After the hanging tray is transferred from the assembly platform to the conveyor belt by the third manipulator, the ground wire is fixed on the hanging tray. The conveyor belt transports the assembled hanging tray to the packaging station.

[0019] By adopting the above technical solution, the third robot transfers the hanging tray from the assembly platform to the conveyor belt, and the staff fixes the ground wire on the hanging tray.
