[0034] In order to more clearly understand the technical means of the present invention and be able to implement it in accordance with the content of the specification, the following further describes in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention but not to limit the scope of the present invention.

[0035] Please refer to Figures 1 to 4 As shown, the present invention discloses an automatic screw locking machine 100, which includes a working platform 1, a feeding component 2, a suction nozzle component 3, and a grasping component 4 provided on the working platform 1. The working platform 1 is provided with a processing area 10 for locking screws to the workpiece to be processed. During use, the grasping component 4 first grasps the suction nozzle 31 on the suction nozzle component 3 and fixes it at the end of the grasping component 4, then adsorbs the screws of the feeding component 2 and moves them above the processing area 10 to lock the screws to the workpiece to be processed in the processing area 10.

[0036] Preferably, the suction nozzle component 3 is provided with at least two storage racks 30 for storing two suction nozzles 31 of different specifications. The multiple suction nozzles 31 of different specifications are used to adapt to different specifications of screws so as to be replaced in time when one of the suction nozzles 31 is worn.

[0037] The feeding component 2 is used to store screws. The automatic screw locking machine 100 further includes a driving component 20, which can actively drive the feeding component 2 to vibrate so as to transport the screws to the tray 21. Therefore, the grasping component 4 adsorbs the screws on the tray 21 after grasping and fixing the suction nozzle 31.

[0038] Preferably, the feeding component 2 includes a bin 22 and a transport bridge 23 arranged relative to the bin 22. The transport bridge 23 is connected to the driving component 20 and is used to receive the screws in the bin 22. During use, the screws in the bin 22 are first partially stacked on the transport bridge 23 and move relative to the transport bridge 23 under the drive of the driving component 20 relying on the vibration of the transport bridge 23, and are moved to the tray 21 through the transport bridge 23.

[0039] The grasping component 4 pivots on the working platform 1, and the tray 21, the processing area 10, and the suction nozzle component 3 are all within the rotation range of the grasping component 4.

[0040] The automatic screw locking machine 100 further includes a controller 5, which is electrically connected to the driving assembly 20 and the grasping assembly 4 respectively, and can activate / deactivate the driving assembly 20 and / or drive the grasping assembly 4 to rotate relative to the working platform 1 or drive the grasping assembly 4 to approach / away from the working platform 1.

[0041] The controller 5 is configured to:

[0042] Activate the driving assembly 20 and control the screws to be transported to the tray 21; preferably, the controller 5 is configured to activate the driving assembly 20 to drive the transport bridge 23 to vibrate and transport the screws on the transport bridge 23 into the tray 21;

[0043] Drive the grasping assembly 4 to rotate above the nozzle assembly 3;

[0044] Drive the grasping assembly 4 to approach the working platform 1 and grasp the nozzle 31 stored on any storage rack 30 of the nozzle assembly 3; preferably, the position of each nozzle 31 can be set in advance by coordinates inside the controller 5, so that the accuracy of selecting the nozzle 31 can be ensured.

[0045] Drive the grasping assembly 4 to rotate above the tray 21 and adsorb the screws on the tray 21 through the nozzle 31;

[0046] Drive the grasping assembly 4 to rotate above the processing area 10 and lock the screws onto the workpiece to be processed.

[0047] Preferably, the automatic screw locking machine 100 further includes a camera module 6 located above the tray 21. The controller 5 is electrically connected to the camera module 6 and is configured to be able to drive the camera module 6 to photograph and record the screw information on the tray 21.

[0048] Preferably, the camera module 6 can also record the information of the processing area 10 to record the locking position and locking quality of the screws. Therefore, the camera module 6 photographs and records the processing area 10 twice, once before locking the screws and once after locking the screws. In this way, the controller 5 analyzes the recorded information of these two times to provide guidance for the locking position of the screws and detect the locking quality of the screws.

[0049] The screw information includes the shadow area of all the screws on the tray 21 relative to the tray 21 and the status of each screw. When the shadow area is less than the preset area in the controller 5, the controller 5 controls the driving assembly 20 to vibrate, and causes the feeding assembly 2 to vibrate to transport the stored screws to the tray 21. In this way, the automatic replenishment of the automatic screw locking machine 100 is realized.

[0050] The controller 5 is configured to be able to analyze the screw information and select screws according to the status of each screw on the tray 21 obtained by analyzing the screw information. For example, select screws of the specification corresponding to the currently used suction nozzle 31. In this way, two different specifications of screws can be placed in the magazine 22 at the same time without worrying about affecting the use. In addition, the status of the screws also includes the length, wear condition, etc. of the screws, so that the screws locked on the workpiece to be processed are all intact.

[0051] The automatic screw locking machine 100 further includes a vibration assembly 211 that can drive the tray 21 to vibrate. The vibration assembly 211 is electrically connected to the controller 5. After the controller 5 cannot select screws according to the status of each screw on the tray 21 obtained by analyzing the screw information, the controller 5 drives the vibration assembly 211 to vibrate and controls the camera module 6 to photograph and record the new screw information on the tray 21. Therefore, when all the screws on the current tray 21 have not been selected, the tray 21 can be vibrated by driving the vibration assembly 211, so as to change the status of the screws on the tray 21. After being re-recorded by the camera module 6, they are analyzed by the controller 5 again and re-screened. In this way, the full automation of the screening is realized.

[0052] The automatic screw locking machine 100 further includes a counting module 7. The controller 5 is electrically connected to the counting module 7. After the screws are locked on the workpiece to be processed, the controller 5 drives the counting module 7 to increment the recorded value by 1. In this way, the automatic counting function of the automatic screw locking machine 100 is realized to clearly record how many workpieces to be processed.

[0053] The automatic screw locking machine 100 further includes a display 8 exposed outside the automatic screw locking machine 100 and a control button 9 located beside the display 8. The controller 5 is electrically connected to the control button 9 and the display 8 respectively. Because various operation interfaces corresponding to the functions of the controller 5 will be displayed on the display 8 and controlled through the control button 9 to manually operate the controller 5, such as replacing suction nozzles 31 of different specifications, replenishing materials in advance, etc.

[0054] Preferably, the automatic screw locking machine 100 further includes a torque switching module connected to the controller 5, and the torque switching module can be controlled by the controller 5 to adjust different locking torques when using screws of different specifications.

[0055] Please refer to Figure 5 As shown, the present invention also discloses a control method for an automatic screw locking machine 100, and the control method includes:

[0056] The controller 5 drives the grasping assembly 4 to rotate above the nozzle assembly 3;

[0057] The controller 5 drives the grasping assembly 4 to approach the working platform 1 and grasp a nozzle 31 stored on any storage rack 30 of the nozzle assembly 3;

[0058] The camera module 6 photographs and records the screw information on the tray 21 and transmits it to the controller 5 for analysis;

[0059] The controller 5 drives the grasping assembly 4 to rotate above the tray 21 by analyzing the screw information, and adsorbs the screw on the tray 21 through the nozzle 31, and the screw corresponds to the specification of the nozzle 31;

[0060] The camera module 6 photographs and records the pre-locking information of the processing area 10 and transmits it to the controller 5 for analysis;

[0061] The controller 5 drives the grasping assembly 4 to rotate above the processing area 10 by analyzing the pre-locking information and locks the screw on the workpiece to be processed;

[0062] The camera module 6 photographs and records the post-locking information of the processing area 10 and transmits it to the controller 5 for analysis to judge the locking quality of the screw;

[0063] The controller 5 drives the counting module 7 to increment the recorded value by 1.

[0064] In summary, the automatic screw locking machine 100 and its control method of the present invention configure the controller 5 to: activate the driving component 20 and control the screws to be transported to the tray 21; drive the grasping component 4 to rotate above the nozzle component 3; drive the grasping component 4 to approach the working platform 1 and grasp the nozzle 31 stored on any storage rack 30 of the nozzle component 3; drive the grasping component 4 to rotate above the tray 21 and adsorb the screws on the tray 21 through the nozzle 31; drive the grasping component 4 to rotate above the processing area 10 and lock the screws onto the workpiece to be processed. In this way, not only can different nozzles 31 be used to adsorb screws of different specifications, but also the driving component 20 can be activated to replenish the screws on the tray 21, saving labor and having practicality.

[0065] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
