Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0038] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0039] refer to Figures 1 to 5 According to the locking device of the embodiment of the present application, it includes a driving assembly 100, a screwdriver bit 210, a guide assembly 300, an elastic member 220 and a magnetic member 230. The screwdriver bit 210 is connected to the driving assembly 100. The driving assembly 100 is used to drive the screwdriver bit 210 to rotate around a first direction. The screwdriver bit 210 abuts against the screw to achieve the screwing action of the screw. Along the first direction, the guide assembly 300 is provided with a first through hole 330. The screwdriver bit 210 is inserted into the first through hole 330 and is slidably connected to the guide assembly 300. The guide assembly 300 is slidably connected to the driving assembly 100. The screwdriver bit 210 and the driving assembly 100 guide the guide assembly 300 to prevent the guide assembly 300 from deflecting relative to the first direction. The sliding of the guide assembly 300 is used to avoid the workpiece so that the screwdriver bit 210 can extend into the screw hole to abut against the screw. The magnetic member 230 30 is connected to the guide component 300. Along the first direction, the magnetic component 230 is located at one end of the guide component 300 away from the elastic component 220. The magnetic component 230 can be a magnet. The magnetic component 230 is used to adsorb screws. The magnetic component 230 is provided with a second through hole 231. The screwdriver bit 210 is passed through the second through hole 231. The screwdriver bit 210 is avoided on the basis of ensuring the adsorption effect. The adsorption of the magnetic component 230 facilitates the docking between the screw and the screwdriver bit 210, thereby realizing the locking of the screw.

[0040] The elastic member 220 surrounds the outer peripheral wall of the screwdriver bit 210. Along the first direction, one end of the elastic member 220 abuts the driving assembly 100, and the other end abuts the guide assembly 300. During the locking operation, the workpiece is provided with a screw hole for the screw to penetrate. The guide assembly 300 abuts the workpiece and drives the magnetic member 230 to move synchronously to ensure that the screwdriver bit 210 can extend into the screw hole to lock the screw. The guide assembly 300 abuts the elastic member 220, and the elastic member 220 is compressed. When the screw is locked, the guide assembly 300 slides relative to the screwdriver bit 210 along the first direction under the action of the elastic member 220, thereby re-accommodating the screwdriver bit 210 into the first through hole 330 to avoid the end of the screwdriver bit 210 from being exposed. At the same time, the guide assembly 300 synchronously drives the magnetic member 230 to move, so that the position of the magnetic member 230 is close to the end of the screwdriver bit 210, which is convenient for the screw and the screwdriver bit 210 to dock.

[0041] Specifically, the screwdriver bit 210 has multiple types, and the head shapes of the screwdriver bit 210 include straight-shaped, cross-shaped and hexagonal types. Along the first direction, the driving assembly 100 is connected to the end of the screwdriver bit 210 that is not provided with a head shape. The screwdriver bit 210 is inserted into the first through hole 330, and the magnetic suction member 230 is located at the end of the first through hole 330 away from the elastic member 220, so that the screw and the screwdriver bit 210 are closer. The magnetic suction member 230 absorbs the screw through its own magnetic properties. Compared with absorption methods such as air pressure, there is no need to set up additional power devices such as air pumps and air pipes, and it is easier to adapt to different working scenarios.

[0042] After the magnetic component 230 absorbs the screw, the movement of the locking device drives the screw to the location of the screw hole and inserts the screw into the screw hole. The axis of the screw bit 210 is collinear with the axis of the screw hole. The guide assembly 300 abuts the workpiece and moves relative to the screw bit 210 along the first direction. The screw bit 210 passes through the first through hole 330 and extends into the screw hole to lock the screw. The guide assembly 300 drives the magnetic component 230 to move relative to the screw bit 210. The magnetic component 230 gradually moves away from the screw, and the adsorption force of the magnetic component 230 on the screw gradually weakens, which is beneficial to reduce the influence of the magnetic component 230 on the locking of the screw.

[0043] It should be noted that when the bit 210 is inserted into the screw hole and abuts the screw, the bit 210 abuts against and rotates relative to the screw in a first direction, and the bit 210 is inserted into the locking groove at the screw head by rotating, thereby driving the screw to rotate to achieve locking. In addition, the locking device also includes a judgment of the completion of the locking operation. For example, the driving component 100 can be a servo motor, and the bit 210 drives the screw to rotate. There is a certain torque between the bit 210 and the screw. When the torque reaches a preset torque value, it can be judged that the screw locking operation is completed, and the driving component 100 stops outputting torque.

[0044] refer to Figures 3 to 5In some embodiments, the guide assembly 300 includes a first guide member 310 and a second guide member 320. Along the first direction, the first guide member 310 is slidably connected to the driving assembly 100, and the second guide member 320 is connected to the first guide member 310. The first guide member 310 and the second guide member 320 jointly define a first through hole 330. Along the first direction, one side of the magnetic member 230 abuts against the first guide member 310, and the other side of the magnetic member 230 abuts against the second guide member 320. The first guide member 310 and the second guide member 320 are used to fix the magnetic member 230 to facilitate the disassembly, assembly and maintenance of the magnetic member 230.

[0045] Specifically, the first guide member 310 slides relative to the driving component 100, driving the second guide member 320 and the magnetic member 230 to move relative to the driving component 100. The magnetic member 230 is fixed by the first guide member 310 and the second guide member 320. Compared with the integrated structure, it is convenient for the disassembly, assembly and maintenance of the magnetic member 230. The first guide member 310 has a first extension dimension along the first direction, which is used to ensure the moving stroke of the first guide member 310, the second guide member 320 and the magnetic member 230 along the first direction. The second guide member 320 has a second extension dimension along the first direction. The first extension dimension is greater than the second extension dimension. On the basis of ensuring the moving stroke, the extension dimension of the guide component 300 along the first direction can be reduced, and the structure of the guide component 300 is more compact.

[0046] refer to Figures 3 to 5 In some embodiments, the first through hole 330 includes a first hole segment 311 and a second hole segment 321. The first guide member 310 defines the first hole segment 311, and the second guide member 320 defines the second hole segment 321. The aperture of the second hole segment 321 is larger than the aperture of the first hole segment 311. The first hole segment 311 is connected to the second through hole 231, and the second through hole 231 is connected to the second hole segment 321. Along the first direction, the second through hole 231 is located between the first hole segment 311 and the second through hole 231. Between the hole sections 321, that is, the magnetic attraction member 230 is arranged close to the second hole section 321, and the magnetic attraction member 230 is used to absorb the screw into the second hole section 321. The axes of the second hole section 321 and the first hole section 311 are colinear, and the screwdriver bit 210 is inserted into the first hole section 311. The second hole section 321 is used to provide a guide for the screw, so that the axial direction of the screw is colinear with the axial direction of the screwdriver bit 210, which is convenient for the screwdriver bit 210 to lock the screw, which is beneficial to improving the efficiency of the locking operation.

[0047] Specifically, the first hole segment 311, the second through hole 231 and the second hole segment 321 are coaxially arranged. The first hole segment 311 is used to provide a guide for the movement of the guide assembly 300, and the second hole segment 321 is used to provide a guide for the screw, ensuring that the axis of the screw adsorbed by the magnetic suction component 230 is colinear with the axis of the screw bit 210, which facilitates the screw locking by the screw bit 210, makes the transmission between the screw bit 210 and the screw more stable, and also facilitates the alignment of the screw and the screw hole, thereby improving the efficiency of the locking operation.

[0048] refer to Figures 3 to 5 In some embodiments, a fixing portion 323 is protruded from the inner wall of the second guide member 320, and the fixing portion 323 defines a portion of the first through hole 330, that is, defines a portion of the second hole section 321 of the first through hole 330. Along the first direction, one side of the magnetic member 230 abuts the fixing portion 323, and the other side of the magnetic member 230 abuts the second guide member 320. The fixing portion 323 is used to carry the magnetic member 230 and fix the magnetic member 230 together with the second guide member 320, so as to more stably fix the magnetic member 230. Compared with the magnetic member 230 abutting against the side wall of the second guide member 320, the axis of the second through hole 231 is effectively avoided from being tilted relative to the axis of the first through hole 330, thereby improving the smoothness of sliding between the guide assembly 300 and the bit 210.

[0049] Specifically, along the first direction, both sides of the magnetic component 230 are planes, the fixing portion 323 abuts one side of the magnetic component 230 through a plane, and the first guide member 310 abuts the other side of the magnetic component 230 through a plane, thereby ensuring that the axis of the second through hole 231 is colinear with the axis of the first through hole 330 and making it easier to install the magnetic component 230.

[0050] refer to Figures 3 to 5 In some embodiments, the second guide member 320 is provided with a connecting cavity 324, a portion of the first guide member 310 penetrates into the connecting cavity 324 and is connected to the second guide member 320, the magnetic member 230 is located in the connecting cavity 324, and along the first direction, one side of the magnetic member 230 abuts against the first guide member 310, and the other side of the magnetic member 230 abuts against the second guide member 320. The connection method between the first guide member 310 and the second guide member 320 shortens the extension dimension of the guide assembly 300 along the first direction, and the overall structure of the locking device is more compact.

[0051] It should be noted that the magnetic component 230 is located in the connecting cavity 324 to effectively prevent damage and ensure the integrity and magnetic function of the magnetic component 230. The fixing portion 323 defines a second hole section 321, and the magnetic component 230 is provided with a second through hole 231. The aperture of the second hole section 321 is larger than the second through hole 231. Thus, the inner wall edge of the magnetic component 230 exceeds the inner wall edge of the fixing portion 323, and the screw head is accommodated in the second hole section 321 and can contact the magnetic component 230, which is beneficial to ensure the stability of the magnetic attraction.

[0052] refer to Figure 2 and Figure 3 In some embodiments, the driving assembly 100 includes a driving member 110 and a connecting member 120, which are connected to define a accommodating chamber 130. The connecting member 120 is used to protect the locking device, for example, to prevent debris from interfering with the sliding between the guide assembly 300 and the connecting member 120. The connecting member 120 is provided with a third through hole 122, and the third through hole 122 is connected to the accommodating chamber 130. The screwdriver bit 210 passes through the third through hole 122 to the accommodating chamber 130 and is connected to the driving member 110. At least a portion of the guide assembly 300 passes through the third through hole 122 and is located in the accommodating chamber 130, and the outer peripheral wall of the guide assembly 300 slides against the hole wall of the third through hole 122 to further isolate the debris outside the accommodating chamber 130.

[0053] The guide assembly 300 is slidably connected relative to the connecting member 120 along a first direction. As the guide assembly 300 slides relative to the connecting member 120, the volume of the guide assembly 300 in the accommodating chamber 130 changes, thereby causing the volume of the accommodating chamber 130 to change. The volume change of the accommodating chamber 130 is equal to the volume change of the guide assembly 300 entering and exiting the accommodating chamber 130. Compared with the guide assembly 300 abutting against the cavity wall of the accommodating chamber 130 and separating a chamber in the accommodating chamber 130, it is beneficial to reduce the change in the volume of the accommodating chamber 130, so that the sliding of the guide assembly 300 relative to the connecting member 120 is smoother.

[0054] Specifically, the accommodating chamber 130 is a cylindrical cavity, and the aperture of the third through hole 122 is smaller than the aperture of the top surface or the bottom surface of the cylindrical cavity. The sliding of the guide component 300 relative to the connecting member 120 will change the volume of the accommodating chamber 130. The reduction in the volume of the accommodating chamber 130 will compress the air in the accommodating chamber 130. Compared with the guide component 300 abutting against the inner wall of the accommodating chamber 130 along the second direction, the abutment against the hole wall of the third through hole 122 can not only ensure the sliding connection between the guide component 300 and the connecting member 120, but also reduce the volume change of the accommodating chamber 130 caused by the relative sliding between the two. Along the first direction, when the guide component 300 moves the same distance relative to the connecting member 120, the abutment of the guide component 300 against the aperture of the third through hole 122 can reduce the compression of the air in the accommodating chamber 130, thereby encountering less resistance and the guide component 300 sliding relative to the connecting member 120 more smoothly.

[0055] refer to Figures 3 to 5In some embodiments, the outer wall of the guide assembly 300 is convexly provided with a first limiting portion 312. Along the first direction, the first limiting portion 312 is located in the accommodating chamber 130. The first limiting portion 312 is used to abut the connecting member 120 along the first direction to prevent the guide assembly 300 from being separated from the connecting member 120 and maintain the sliding connection between the guide assembly 300 and the connecting member 120. In addition, along the second direction, there is a gap between the first limiting portion 312 and the cavity wall of the accommodating chamber 130. The second direction is perpendicular to the first direction and is used to avoid separating the accommodating chamber 130, thereby reducing the impact of the sliding of the guide assembly 300 relative to the connecting member 120 on the volume of the accommodating chamber 130, that is, reducing the degree of compression of the gas in the accommodating chamber 130, and ensuring the sliding connection between the guide assembly 300 and the connecting member 120, so that the sliding of the two is smoother.

[0056] refer to Figures 3 to 5 In other embodiments, the guide assembly 300 includes a first limiting portion 312 protruding from the outer peripheral wall, and the outer peripheral wall of the guide assembly 300 abuts against the hole wall of the third through hole 122 to achieve a sliding connection between the guide assembly 300 and the connecting member 120. The first limiting portion 312 is located in the accommodating cavity 130 and is used to limit the guide assembly 300 from being separated from the connecting member 120. When the guide assembly 300 is separated from the connecting member 120, the first limiting portion 312 abuts against the connecting member 120 along the first direction to ensure the connection between the guide assembly 300 and the connecting member 120. The volume change of the accommodating cavity 130 is the same as the volume change of the guide assembly 300 entering and exiting the accommodating cavity 130. Compared with the sliding connection achieved by the first limiting portion 312 abutting against the inner peripheral wall of the accommodating cavity 130 along the second direction, the impact on the volume of the accommodating cavity 130 is reduced.

[0057] It should be noted that there is air in the accommodating chamber 130. When the guide assembly 300 enters the accommodating chamber 130, it will occupy the volume of the accommodating chamber 130, and then the air in the accommodating chamber 130 will be compressed to increase the air pressure, thereby reducing the impact on the volume of the accommodating chamber 130, which is beneficial to reducing the compression amount of the air, and thus is beneficial to reducing the resistance of the air pressure to the relative sliding of the guide assembly 300 and the connecting member 120.

[0058] refer to Figures 3 to 5 In some embodiments, a second limiting portion 322 is protruding from the outer wall of the guide assembly 300. The second limiting portion 322 is located outside the accommodating cavity 130. The second limiting portion 322 is configured to abut the connecting member 120 along the first direction to limit the compression amount of the elastic member 220 to prevent the elastic member 220 from being over-extruded and failing.

[0059] Specifically, during the locking operation, the guide assembly 300 abuts against the workpiece and slides relative to the connecting member 120, and the elastic member 220 is abutted and compressed by the guide assembly 300. The second limiting portion 322 is protruded from the outer peripheral wall of the guide assembly 300 and is located outside the accommodating cavity 130. It is used to limit the guide assembly 300 from over-compressing the elastic member 220, prevent the elastic member 220 from being over-extruded and failing, and prevent the guide assembly 300 from entering the accommodating cavity 130 as a whole, thereby ensuring the rebound of the elastic member 220.

[0060] refer to Figure 2 In some embodiments, the driving assembly 100 is provided with a connecting portion 121, and the connecting portion 121 includes a connecting plane perpendicular to the first direction. The axis of the screwdriver bit 210 passes through the center of the connecting plane. The connecting portion 121 is used for connection with external components such as a robotic arm, so as to facilitate determination of the relative position of the external components and the locking assembly. The center of the connecting plane can be used as a calculation origin, which is beneficial to improving the accuracy of position or angle adjustment.

[0061] refer to Figure 6 According to the locking device of the embodiment of the present application, it includes a mobile device 410, an image recognition device 420 and the locking device in any of the above embodiments. The image recognition device 420 is connected to the mobile device 410. The image recognition device 420 has an image recognition range, which is used to identify the position of the screw hole on the workpiece and the posture of the screw, ensuring that the axis of the screw is colinear with the axis of the screw hole, so as to more accurately lock the screw in the screw hole. The locking device is connected to the mobile device 410, and the locking device is located within the image recognition range, which is convenient for the image recognition device 420 to identify the posture of the screw adsorbed by the locking device. The mobile device 410 is used to drive the locking device and the image recognition device 420 to move together to drive the screw to approach the screw hole to achieve the locking of the screw.
