[0034] Example 2

[0035] This embodiment provides a charger installation screw loading and unloading device, which is different from the embodiment 1 in that, in this embodiment, Figure 5 and Figure 7 As shown, to facilitate automatic screw driving, an automatic screw tightening unit is installed next to the support base 1. Below the automatic screw tightening unit is a forward and backward linear module 16, on which a rotary positioning mechanism is slidably mounted. The rotary positioning mechanism is used to receive the charger 6 transported by the robot gripper 7.

[0036] In this embodiment, to facilitate screwing into the top and two side surfaces of the charger, the rotational positioning mechanism includes a movable base 14. The movable base 14 is slidably mounted on the front and rear linear modules 16 via a fixed plate 24. A set of rotational support seats 27 are disposed opposite each other on the movable base 14.

The length of the belt conveyor 34 is greater than the length of the support base 1.

[0041] Specifically, the specific operation process of the charger installation screw loading and unloading device provided by the utility model is as follows:

[0042] After assembling the lower case of the charger, snap on the upper case and place it into the first L-shaped positioning block group in the loading and unloading tray mechanism. The push rod then transports the upper and lower cases of the charger in the loading and unloading tray mechanism to the designated position. The rotating manipulator grabs the material and rotates it to the screw-driving station on the screw machine. In this embodiment, to ensure uninterrupted operation, the manual discharge position is divided into three stations. After the charger is placed in the first L-shaped positioning block group, a 2mm gap can be set in the front, back, left, and right directions. After manual discharge is completed, press the control button to confirm the completion of material discharge and activate the corresponding push rod. Once the push rod moves into position, the proximity switch confirms the material position and the arrival signal, allowing the rotating manipulator to grab the material.

[0043] The robot's specific operation for grabbing and releasing the charger is as follows: After unloading, the rotating robot grabs the charger and transfers it to the screw machine for screwing. The screw machine is a separate mechanism and can be used as a standalone screw machine without the robot. After screwing, the rotating robot removes the material from the screw machine and places it on a belt conveyor for the next process. The grabbing, transfer, and release actions of the rotating robot all use existing operating procedures and control methods.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
