Description

Technical Field

[0001] The present invention relates to the technical field of computer assembly, and specifically, it is an automatic screw locking device for notebook computers. Background Art

[0002] The outer shell of a notebook computer usually consists of multiple parts. When assembling the outer shell of a notebook computer, it is necessary to place materials multiple times and use screws for fastening. The order of placing materials is determined according to the assembly steps. For each hole position, screws of appropriate specifications are used according to the actual situation. Check whether the positions of the screw holes correspond accurately to avoid the situation where the screw holes are misaligned and the screws cannot be properly installed. Generally speaking, the screws should be tightened gradually from the middle to both sides and from the symmetric positions to ensure uniform stress on each part and avoid problems such as shell deformation or screw loosening. After tightening the screws, check the hole positions to ensure that screws are properly installed in each hole position.

[0003] Chinese Patent CN218695840U proposed an automatic assembly and screw locking device for notebook computers, including a base plate. A workbench is slidably installed on the upper side of the base plate. A column is slidably installed on one side of the base plate. A screw locking machine is slidably installed on the side of the column. Locking seats are slidably installed on both sides of the base plate. A threaded rod is inserted through the side of the locking seat. The threaded rod is threadedly connected to the locking seat. A turning handle is rotated at one end of the threaded rod, and a mounting plate is rotated at the other end of the threaded rod. An extrusion roller is rotatably installed on the side of the mounting plate. By rotating the turning handle to change the position of the threaded rod, the extrusion roller can be used to clamp the notebook computer, so that when the screw locking machine works, the notebook computer can be kept as stable as possible, improving the quality of assembly.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent uses the extrusion roller to clamp the notebook computer by rotating the turning handle to change the position of the threaded rod, but it cannot perform multiple clamping and positioning on the notebook and cannot load and unload materials quickly.

[0006] 2. This patent cannot perform multi-station continuous automatic screw locking on the notebook, and the assembly efficiency is relatively low.

[0007] Based on this, the present invention designs an automatic screw locking device for notebook computers to solve the above problems. Summary of the Invention

If there is no notebook, the external controller controls the unlocking component to open the length clamping component. The notebook is transported to the backing plate of the clamping mechanism of the turntable device by the manipulator handling component. When the photoelectric sensor detects that there is a notebook on the backing plate, the external controller controls the unlocking component to unlock the length clamping component to restore it to the initial state, and the length clamping component clamps one side wall of the notebook; when the photoelectric sensor detects that there is a notebook on the backing plate, the external controller controls the width clamping component to start and clamp one side wall of the notebook; at the same time, the external controller controls the suction cup to start and adsorb the notebook. Through multiple clamps, it is beneficial to quickly fix the notebook and maintain the stability of the notebook;

[0022] 2. On the station in front of the pneumatic indexing table, the materials at the USB interface are assembled. Multiple materials at the USB interface are placed on the notebook manually, and the external controller controls the third rotary pressing cylinder of the positioning component to start. The output end of the third rotary pressing cylinder shortens and rotates simultaneously, pushing the lever, causing the lever to move towards the notebook. The movement of the lever towards the notebook drives the sliding top plate to move towards the notebook, and the movement of the sliding top plate towards the notebook drives the mold opening positioning head to move towards the notebook. The mold opening positioning head is fixed by being stuck at the closing spring piece, aligning the materials at the USB interface with the notebook and fixing the materials at the USB interface simultaneously, preventing the materials at the USB interface from moving when the pneumatic indexing table rotates. It is beneficial to align the materials at the USB interface with the notebook and fix the materials at the USB interface simultaneously, preventing the materials at the USB interface from moving when the pneumatic indexing table rotates. The notebook is locked with screws at multiple stations through multiple screw locking devices, and the multi-station transfer of the notebook is realized through the turntable device, improving the assembly efficiency of the notebook;

[0023] 3. On the station on the left side of the pneumatic indexing table, the robotic arm of the manipulator handling component starts, moves the pneumatic gripper to the station on the left side of the pneumatic indexing table. The external controller controls the output end of the first cylinder to extend. The extension of the output end of the first cylinder drives the rotating plate to rotate to the right on the third base, causing the pneumatic gripper to rotate to the right. The pneumatic gripper starts to clamp the assembled notebook, and the robotic arm starts to place the assembled notebook on the modified uphill flow line device. Through the left and right offset of the pneumatic gripper, it is beneficial for inclined material clamping and discharging, facilitating rapid loading and unloading. Description of the Drawings

The unlocking rod 85 enters the slot position at the rear side of the first sliding plate 813, so that the first sliding plate 813 is pulled towards the center position of the pneumatic indexing table 81, causing the first spring 816 to be compressed. The movement of the first sliding plate 813 towards the center position of the pneumatic indexing table 81 drives the first positioning block 815 to move towards the center position of the pneumatic indexing table 81. The notebook is transported to the backing plate 88 of the clamping mechanism of the turntable device 8 by the manipulator handling assembly 6. The photoelectric sensor 86 detects that a notebook appears on the backing plate 88. The external controller controls the first rotary pressing cylinder 84 to return to the initial state, and the compressed spring is restored, pushing the first sliding plate 813 back to the initial position, so that the first positioning block 815 returns to the initial position to clamp the notebook.

[0059] The photoelectric sensor 86 detects that a notebook appears on the backing plate 88. The external controller controls the second rotary pressing cylinder 810 to start. The output end of the second rotary pressing cylinder 810 extends and rotates, and the output end of the second sliding plate 818 leaves the second sliding plate 818. The compressed second spring 821 is restored, pushing the second sliding plate 818 towards the notebook direction. The movement of the second sliding plate 818 towards the notebook direction drives the second positioning block 820 to move towards the notebook direction to clamp the notebook.
