[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1 to Figure 2 As shown, in this embodiment, a hidden screw locking mechanism includes a base 1, a positioning conversion camera 2, a servo upper and lower modules 3, a rotating module 4 and an electric screwdriver 5. A gantry 6 is installed above the base 1, and a transverse moving module 7 is installed on the gantry 6. The positioning conversion camera 2 and the servo upper and lower modules 3 are both installed on the driving end of the transverse moving module 7, the rotating module 4 is installed on the driving end of the servo upper and lower modules 3, and the electric screwdriver 5 is installed on the driving end of the rotating module 4.

[0019] When it is necessary to tighten the screws, the positioning conversion camera 2 performs CCD positioning conversion, controls the up and down movement of the servo upper and lower modules 3, adjusts the angle of the rotating module 4, and inserts the electric screwdriver 5 into the fan to tighten the screws.

[0020] Moreover, a forward and backward moving module 8 is installed on the base 1, a carrier 9 is installed on the driving end of the forward and backward moving module 8, a first driving motor 10 is fixed to the rear end of the forward and backward moving module 8, the first driving motor 10 controls the carrier 9 to move forward and backward along the forward and backward moving module 8 through the transmission of the screw rod and the nut, a second driving motor 11 is fixed to one side of the transverse moving module 7, the second driving motor 11 controls the positioning conversion camera 2 and the servo upper and lower modules 3 to move left and right along the transverse moving module 7 through the transmission of the screw rod and the nut, the outer side of the positioning conversion camera 2 is covered with a protective cover 12, a light source 13 is arranged under the positioning conversion camera 2, and a clamp 14 is installed at the front end of the rotating module 4, and the clamp 14 clamps the electric screwdriver 5.

[0021] The operation of the entire mechanism is controlled by PLC, and two sets of screw locking operations can be performed simultaneously. The electric screwdriver 5 is clamped on the opened clamp 14 in advance, and the operator places the fan product on the carrier 9. After starting the switch, the first drive motor 10 controls the forward and backward moving module 8 to move the fan product to the bottom of the positioning conversion camera 2. With the assistance of the light source 13, the positioning conversion camera 2 starts the CCD to position and convert the fan product to obtain the position of the screw. After finding the correct position, it simulates manual screw locking. After obtaining the result, the second drive motor 11 starts to control the lateral moving module 7 to move left and right, and controls the electric screwdriver 5 to move to the top of the fan product. The servo upper and lower modules 3 control the electric screwdriver 5 to move downward, and then the rotating module 4 controls the electric screwdriver 5 to rotate at an angle, and the electric screwdriver 5 is inserted from between the blades of the fan product to the screw position. Subsequently, the electric screwdriver 5 is removed from the fan product, and the forward and backward moving module 8 moves the fan product out again, and the operator can put it away.

[0022] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
