Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a locking mechanism and a locking device. Background Art

[0002] With the continuous improvement of battery production efficiency, in the process of battery production, most of the structural component connections, fixing / anti-theft / sealing, etc. are inseparable from screw connections. Among them, when locking screws arranged horizontally, inverted, or obliquely, when the screw axis is not perpendicular to the locking station, it is easy to cause abnormalities such as skewing, screw dropping, and floating during the screw locking process. Moreover, when locking screws, in addition to the screws being perpendicular to the ground (the screws remain perpendicular to the ground under the action of gravity), there are also occasions where the screws are parallel, inclined, or reversely perpendicular to the workpiece (or the ground). When the screws move with acceleration under the action of gravity or during the rapid displacement of the locking mechanism, the axis of the screw is offset from the axis of the threaded hole, resulting in abnormal locking and affecting the yield rate of locking. Summary of the Utility Model

[0003] In order to solve or partially solve the above problems, the utility model discloses a locking mechanism and a locking device to solve the problem that the yield rate of locking is affected due to the change of the relative position of the screw during the screw locking process in the prior art.

One end of the second elastic member in the second direction is fixed on the side of the second clamping block facing the first clamping block, and the other end of the second elastic member in the second direction abuts against the outer wall of the locking sleeve. Among them, the first elastic member and the second elastic member are in a compressed state.

[0017] Optionally, the diameter of the second end of the locking sleeve is greater than the diameter of other parts of the locking sleeve;

[0032] In summary, when locking the connecting piece by the locking mechanism provided by the embodiment of the present invention, the connecting piece can be limited by the clamping jaw, then the connecting piece is vacuum adsorbed by the adsorption groove, and the connecting piece is limited and connected by the adsorption groove, so that the axis line of the connecting piece and the axis line of the locking sleeve are always on the same straight line. During the process of the electric screwdriver driving the locking sleeve to rotate, the connecting piece will not deviate in position, thereby ensuring the locking yield rate and locking efficiency of the locking mechanism for the connecting piece.

[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present utility model. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in any suitable manner in one or more embodiments.

[0045] Such as Figures 1 to 6As shown in the figure, in a first aspect, an embodiment of the present utility model provides a locking mechanism for locking a connecting member. The locking mechanism includes a first direction X, a second direction Y, and a third direction Z that intersect pairwise. The locking mechanism includes:

[0046] An electric screwdriver 11 and a clamping assembly 12 connected to the end of the electric screwdriver 11 in the first direction X. The clamping assembly 12 and the electric screwdriver 11 move synchronously.

[0047] The clamping assembly 12 includes a clamping jaw 121 and a locking sleeve 122. The first end of the locking sleeve 122 in the first direction X is movably connected to the clamping jaw 121. The second end of the locking sleeve 122 in the first direction X is connected to the electric screwdriver 11. The locking sleeve 122 and the clamping jaw 121 slide relative to each other along the first direction X.

[0048] A vacuum pipeline 1221 is provided in the middle of the locking sleeve 122. An adsorption groove 1222 is provided at the first end of the locking sleeve 122 in the first direction X. The adsorption groove 1222 is used for vacuum adsorption of the connecting member.

[0049] It can be seen from the above embodiments that in the embodiments of the present utility model, since the clamping assembly 12 and the electric screwdriver 11 move synchronously, the electric screwdriver 11 can drive the clamping assembly 12 to rotate synchronously. Also, since the clamping assembly 12 includes a clamping jaw 121 and a locking sleeve 122, the first end of the locking sleeve 122 in the first direction X is movably connected to the clamping jaw 121, the second end of the locking sleeve 122 in the first direction X is connected to the electric screwdriver 11, and the locking sleeve 122 and the clamping jaw 121 slide relative to each other along the first direction X, the electric screwdriver 11 can drive the locking sleeve 122 to rotate synchronously, so that the clamping jaw 121 rotates synchronously with the locking sleeve 122, and the locking sleeve 122 and the clamping jaw 121 can slide relative to each other along the first direction X, that is, the clamping jaw 121 can extend out of the locking sleeve 122 and retract into the locking sleeve 122. In addition, a vacuum pipeline 1221 is provided in the middle of the locking sleeve 122, and an adsorption groove 1222 is provided at the first end of the locking sleeve 122 in the first direction X. The adsorption groove 1222 is used for vacuum adsorption of the connecting member. Therefore, the connecting member can be vacuum-adsorbed in the locking sleeve 122, and under the limiting action of the adsorption groove 1222, the connecting member will not change its relative position due to gravity during fixation, and the axis of the connecting member and the axis of the locking sleeve 122 are always on the same straight line, avoiding the deviation of the connecting member.

[0050] In summary, when the locking mechanism provided by the embodiment of the present utility model locks the connecting piece, the connecting piece can be limited by the clamping jaw 121, and then the connecting piece is vacuum adsorbed through the adsorption groove 1222, and the connecting piece is limited and connected through the adsorption groove 1222, so that the axis line of the connecting piece and the axis line of the locking sleeve 122 are always on the same straight line. During the process that the electric screwdriver 11 drives the locking sleeve 122 to rotate, the position of the connecting piece will not shift, thereby ensuring the locking yield rate and locking efficiency of the locking mechanism for the connecting piece.

[0051] Among them, in the above embodiment, the electric screwdriver 11 is a rod-shaped structure capable of rotating. Exemplarily, the electric screwdriver 11 may include a rotor and a stator. The rotor is driven by a motor to drive the screwdriver bit to rotate, so as to realize the tightening and loosening of the connecting piece. The working principle of the electric screwdriver 11 is similar to that of a servo motor, ensuring the automatic information processing and automatic control functions during the tightening process of the connecting piece, and improving the sensitivity, precision and range of control and detection. In addition, the electric screwdriver 11 may also be an intelligent electric screwdriver. In the embodiment of the present utility model, the connecting piece may be any one of a screw, a bolt, a screw rod or a rivet, etc. that needs to be rotated and screwed into a component. The embodiment of the present utility model does not limit this, and the following will take the connecting piece as a screw as an example for description.

[0052] The clamping assembly 12 connected to the end of the electric screwdriver 11 in the first direction X includes a clamping jaw 121 and a locking sleeve 122. The clamping jaw 121 may be any one of types such as a two-finger clamping jaw 121, a three-finger clamping jaw 121, a five-finger clamping jaw 121, an angular clamping jaw 121, etc. The embodiment of the present utility model does not limit this. The clamping jaw 121 at least includes a clamping portion and a limiting portion. The connecting piece is fixed through the clamping portion, and the connecting piece is limited through the limiting portion to prevent the connecting piece from shifting during the connection process. The locking sleeve 122 can be connected through one or more components such as a coupling, a keyway, a locking screw, etc., so that the locking sleeve 122 can move along with the locking sleeve 122 to realize the tightening of the connecting piece. The locking sleeve 122 may be a hollow tubular structure, and a vacuum pipeline 1221, a vacuum adsorbing member and other structures may be installed in the inner cavity of the locking sleeve 122, so that the locking sleeve 122 can be adsorbed on the end of the locking sleeve 122. The locking sleeve 122 can be movably connected to the clamping jaw 121 through at least one of structures such as a sliding connection, a cylinder drive, a motor lead screw, etc., so that the locking sleeve 122 and the clamping jaw 121 can slide relative to each other along the first direction X, and further the clamping jaw 121 can approach the connecting piece. In addition, the shape of the adsorption groove 1222 provided at the first end of the locking sleeve 122 can be set by imitating the shape of the end of the connecting piece. Exemplarily, when the connecting piece is a screw, the shape of the adsorption groove 1222 is the same as the shape of the nut of the screw. Therefore, the screw can be limited by the adsorption groove 1222 to prevent abnormal situations such as the screw from being sunken or falling off.

[0053] According toFigure 1 In the embodiment of the present utility model, the X-axis direction intersects with the Z-axis direction, the X-axis direction intersects with the Y-axis direction, and the Y-axis direction intersects with the Z-axis direction. For the convenience of description, the first direction is defined as the X-axis direction (that is, the axial direction of the locking sleeve 122 in the embodiment of the present utility model), the second direction is defined as the Y-axis direction, and the third direction is defined as the Z-axis direction. Further explanation, the definition of perpendicular in the specification should be understood as perpendicular when floating within ten percent of ninety degrees, that is, the included angle between the defined first direction and the second direction should be understood as perpendicular when it is between eighty degrees and ninety degrees, the included angle between the defined first direction and the third direction should be understood as perpendicular when it is between eighty degrees and ninety degrees, and the included angle between the defined second direction and the third direction should be understood as perpendicular when it is between eighty degrees and ninety degrees.

[0054] In some embodiments, the locking mechanism further includes a driving member 13; the driving member 13 is movably connected to the locking sleeve 122, and the driving member 13 drives the locking sleeve 122 and the clamping jaw 121 to slide relative to each other along the first direction X.

[0055] It should be noted that the driving member 13 can be any one of driving members 13 that can achieve linear driving, such as a cylinder push rod structure, a motor screw structure, etc. In this way, the driving member 13 can drive the locking sleeve 122 to drive the clamping jaw 121 to approach the connecting member, so that the clamping jaw 121 and the connecting member are fixed. After the connecting member is tightened, the driving member 13 can drive the locking sleeve 122 to move away from the connecting member, which is convenient for installing the next connecting member. During the entire installation process, the driving member 13 can automatically approach and move away from the connecting member, and during the entire process, due to the driving of the driving member 13, it is more convenient for the clamping jaw 121 and the connecting member to be aligned, which is convenient for improving the accuracy of driving.

[0056] In some embodiments, for the structure of the driving member 13, the driving member 13 can include a cylinder 131 and a mounting plate 132, and the clamping jaw 121 includes a first clamping block 1211 and a second clamping block 1212; a clamping hole 1213 is formed between the end of the first clamping block 1211 away from the electric screwdriver 11 in the first direction X and the end of the second clamping block 1212 away from the electric screwdriver 11 in the first direction X; both the first clamping block 1211 and the second clamping block 1212 are mounted on the mounting plate 132, and the push rod of the cylinder 131 is connected to the mounting plate 132. When the push rod of the cylinder 131 retracts, the clamping jaw 121 moves relative to the locking sleeve 122 in the direction close to the electric screwdriver 11 until the first end of the locking sleeve 122 is clamped in the clamping hole 1213. When the push rod of the cylinder 131 extends, the clamping jaw 121 moves relative to the locking sleeve 122 in the direction away from the electric screwdriver 11 until the first end of the locking sleeve 122 retracts from the clamping hole 1213.

[0057] It should be noted that the first clamping block 1211 and the second clamping block 1212 are bar-shaped arm structures. The first clamping block 1211 and the second clamping block 1212 are arranged oppositely. One end of the first clamping block 1211 is fixed on the mounting plate 132, and one end of the first clamping block 1211 is fixed on the clamping block. A clamping hole 1213 is formed between the end of the first clamping block 1211 away from the electric screwdriver 11 in the first direction X and the end of the second clamping block 1212 away from the electric screwdriver 11 in the first direction X, so that a two-finger jaw 121 structure is formed between the first clamping block 1211 and the second clamping block 1212. The first clamping block 1211 extends obliquely, and the second clamping block 1212 extends obliquely, and both are inclined towards the middle position of the first clamping block 1211 and the second clamping block 1212, so that a necking structure is formed between the first clamping block 1211 and the second clamping block 1212. The first clamping block 1211, the second clamping block 1212 and the mounting plate 132 can be connected by one or more of clamping, riveting, threaded connection and other methods, and the embodiments of the present invention do not limit this. Exemplarily, the end of the first clamping block 1211 away from the connecting piece can be threadedly connected to the first connecting frame, and the end of the second clamping block 1212 away from the connecting piece can be threadedly connected to the second connecting frame. The first connecting frame and the second connecting frame can be frame-shaped structures including multiple connecting arms, and then connected through the first connecting frame, the second connecting frame and the mounting plate 132, so that the mounting plate 132 can drive the jaw 121 to move along the first direction X. In this way, when it is necessary to clamp the connecting piece, the push rod of the cylinder 131 can be retracted, so that the push rod drives the mounting plate 132 to move away from the clamping hole 1213, and then the mounting plate 132 drives the jaw 121 to move towards the electric screwdriver 11 relative to the locking sleeve 122 until the first end of the locking sleeve 122 is clamped in the clamping hole 1213, which is convenient for vacuum adsorbing the connecting piece through the adsorption groove 1222 provided at the first end of the locking sleeve 122. After the clamping is completed, the push rod of the cylinder 131 can be extended, so that the push rod drives the mounting plate 132 to move towards the clamping hole 1213, and then the mounting plate 132 drives the jaw 121 to move away from the electric screwdriver 11 relative to the locking sleeve 122 until the first end of the locking sleeve 122 retracts from the clamping hole 1213. In this case, the vacuum parameter in the vacuum pipeline 1221 changes, so that the first end of the locking sleeve 122 is separated from the adsorption of the connecting piece until the first end of the locking sleeve 122 retracts from the clamping hole 1213, which is convenient for the screwing work of the next connecting piece.

[0058] In this embodiment, since the position of the locking sleeve 122 does not change during the whole process, the relative position between the clamping jaw 121 and the locking sleeve 122 is adjusted by the extension and retraction of the air cylinder 131, so as to realize the approach and separation of the locking sleeve 122 from the connecting piece. Therefore, the whole process of adsorbing the connecting piece can be in a linear motion process, that is, during the whole process, only by the extension and retraction of the air cylinder 131 can the adsorption process between the locking sleeve 122 and the connecting piece be accurately controlled to ensure the quality of locking.

[0059] It should be noted that, in the above embodiment, the clamping jaw 121 moves relative to the locking sleeve 122 in the direction close to the electric screwdriver 11. It can be understood that the clamping jaw 121 moves relative to the locking sleeve 122 in the upward direction along the first direction X. The clamping jaw 121 moves relative to the locking sleeve 122 in the direction away from the electric screwdriver 11. It can be understood that the clamping jaw 121 moves relative to the locking sleeve 122 in the downward direction along the first direction X. Among them, the upward and downward directions of the first direction X are two opposite directions on the first direction X.

[0060] In some embodiments, the clamping jaw 121 further includes a first limiting member 1214 and a second limiting member 1215; one end of the first limiting member 1214 in the second direction Y is connected to the first clamping block 1211, and the other end of the first limiting member 1214 in the second direction Y abuts against the locking sleeve 122. One end of the second limiting member 1215 in the second direction Y is connected to the second clamping block 1212, and the other end of the second limiting member 1215 in the second direction Y abuts against the locking sleeve 122.

[0061] In this embodiment, since one end of the first limiting member 1214 in the second direction Y is connected to the first clamping block 1211, the other end of the first limiting member 1214 in the second direction Y abuts against the locking sleeve 122, one end of the second limiting member 1215 in the second direction Y is connected to the second clamping block 1212, and the other end of the second limiting member 1215 in the second direction Y abuts against the locking sleeve 122. Therefore, not only can the first clamping block 1211 be connected through the first limiting member 1214, and the second clamping block 1212 be connected through the second limiting member 1215, but also the locking sleeve 122 can be limited by the opposite ends of the first limiting member 1214 and the second limiting member 1215, ensuring that the axis between the first clamping block 1211 and the second clamping block 1212 is parallel to the axis of the locking sleeve 122, so that the axis of the connecting member is concentric with the axis of the locking sleeve 122, avoiding the offset when the clamping jaw 121 moves relative to the locking sleeve 122, and further ensuring the quality of locking. In addition, since the locking sleeve 122 is limited by the first clamping block 1211 and the second clamping block 1212, and then the connecting member is adsorbed by the locking sleeve 122. In this way, the connecting member can be jointly limited by the locking sleeve 122 and the clamping hole 1213 formed by the first clamping block 1211 and the second clamping block 1212. In this way, even if the locking mechanism moves with acceleration, the displacement in any direction such as horizontal - vertical - oblique - reverse (along the third direction Z upward) can maintain the original initial position after clamping, which can meet the locking of the connecting member at various angles, and the locking process of the connecting member is not restricted by the gravity.

[0062] In some embodiments, the clamping jaw 121 further includes a first elastic member 1216 and a second elastic member 1217; both the first elastic member 1216 and the second elastic member 1217 expand and contract along the second direction Y. One end of the first elastic member 1216 in the second direction Y is fixed on the side of the first clamping block 1211 facing the second clamping block 1212, and the other end of the first elastic member 1216 in the second direction Y abuts against the outer wall of the locking sleeve 122. One end of the second elastic member 1217 in the second direction Y is fixed on the side of the second clamping block 1212 facing the first clamping block 1211, and the other end of the second elastic member 1217 in the second direction Y abuts against the outer wall of the locking sleeve 122. Among them, the first elastic member 1216 and the second elastic member 1217 are in a compressed state.

[0063] In this embodiment, the first elastic member 1216 and the second elastic member 1217 can be components with resilience such as springs, rubber blocks, elastic dampers, etc. The embodiments of the present utility model do not limit this. In this way, by fixing one end of the first elastic member 1216 in the second direction Y on the side of the first clamping block 1211 facing the second clamping block 1212, the other end of the first elastic member 1216 in the second direction Y abuts against the outer wall of the locking sleeve 122, and fixing one end of the second elastic member 1217 in the second direction Y on the side of the second clamping block 1212 facing the first clamping block 1211, and the other end of the second elastic member 1217 in the second direction Y abuts against the outer wall of the locking sleeve 122, it can be ensured that the clamping hole 1213 formed between the first clamping block 1211 and the second clamping block 1212 can be reset under the elastic action of the first elastic member 1216 and the second elastic member 1217, thereby ensuring the locking quality of the locking connector each time.

[0064] In some embodiments, the diameter of the second end of the locking sleeve 122 is greater than the diameter of other parts of the locking sleeve 122; when the locking sleeve 122 moves towards the direction close to the clamping hole 1213 until the second end of the locking sleeve 122 is clamped in the clamping hole 1213, the first elastic member 1216 and the second elastic member 1217 are in the first compression amount, and the diameter of the clamping hole 1213 is the first dimension. When the locking sleeve 122 moves away from the clamping hole 1213 until the second end of the locking sleeve 122 retracts from the clamping hole 1213 and is located between the first elastic member 1216 and the second elastic member 1217, the diameter of the clamping hole 1213 is the second dimension, and the first elastic member 1216 and the second elastic member 1217 are in the second compression amount; wherein, the first compression amount is less than the second compression amount, and the first dimension is greater than the second dimension.

[0065] In this embodiment, when the locking sleeve 122 moves in the direction close to the clamping hole 1213 until the second end of the locking sleeve 122 is clamped in the clamping hole 1213, the first elastic member 1216 and the second elastic member 1217 are in the first compression amount, and the diameter of the clamping hole 1213 is the first size. In this way, it is convenient to limit the locking sleeve 122 through the clamping hole 1213. Also, since the locking sleeve 122 moves in the direction away from the clamping hole 1213 until the second end of the locking sleeve 122 retracts from the clamping hole 1213 and is located between the first elastic member 1216 and the second elastic member 1217, the diameter of the clamping hole 1213 is the second size, the first elastic member 1216 and the second elastic member 1217 are in the second compression amount, the first compression amount is less than the second compression amount, and the first size is greater than the second size. Therefore, when there is a vacuum abnormality in the locking sleeve 122 or the connecting member falls due to inertia, the connecting member can also be clamped in the clamping hole 1213 under the action of the clamping hole 1213, preventing the connecting member from falling and ensuring the safety of the entire locking process.

[0066] In some embodiments, the electric screwdriver 11 includes a connecting shaft 111 and a connector 112; the connector 112 includes a fixed seat, an end cap, and a bearing seat. The middle of the fixed seat is provided with an installation through hole extending along the first direction X. At least two bearing seats are installed in the installation through hole. End caps are installed at both orifices of the installation through hole in the first direction X; the connecting shaft 111 is provided with a vacuum through hole extending along the first direction X at the end facing the locking sleeve 122. The connecting shaft 111 passes through the installation through hole and is coaxially installed with the end cap and the bearing seat. The end of the connecting shaft 111 extending out of the installation through hole is connected to the locking sleeve 122.

[0067] In this embodiment, since the middle of the fixed seat is provided with an installation through hole extending along the first direction X, at least two bearing seats are installed in the installation through hole, the connecting shaft 111 is provided with a vacuum through hole extending along the first direction X at the end facing the locking sleeve 122, the connecting shaft 111 passes through the installation through hole and is coaxially installed with the end cap and the bearing seat, and the end of the connecting shaft 111 extending out of the installation through hole is connected to the locking sleeve 122, the concentricity of the connecting shaft 111 can be ensured by at least two bearing seats, and further the central axis of the locking sleeve 122 connected to the connecting shaft 111 will not shift, ensuring the locking effect of the locking mechanism and facilitating the connection of the middle frame pipeline in the locking sleeve 122 to the vacuum. Also, since end caps are installed at both orifices of the installation through hole in the first direction X, the vacuum through hole can be sealed by the end caps to prevent vacuum leakage and ensure the vacuum adsorption effect of the first end of the locking sleeve 122 on the connecting member.

[0068] As can be seen from the above embodiments, in the embodiments of the present utility model, since the clamping assembly 12 and the electric screwdriver 11 move synchronously, the electric screwdriver 11 can drive the clamping assembly 12 to rotate synchronously. Also, since the clamping assembly 12 includes a clamping jaw 121 and a locking sleeve 122, the first end of the locking sleeve 122 in the first direction X is movably connected to the clamping jaw 121, the second end of the locking sleeve 122 in the first direction X is connected to the electric screwdriver 11, and the locking sleeve 122 and the clamping jaw 121 slide relative to each other in the first direction X. Therefore, the electric screwdriver 11 can drive the locking sleeve 122 to rotate synchronously, and then the clamping jaw can rotate synchronously with the locking sleeve 122, and the locking sleeve 122 and the clamping jaw can slide relative to each other in the first direction X, that is, the clamping jaw can extend out of the locking sleeve 122 and retract into the locking sleeve 122. In addition, a vacuum pipeline 1221 is provided in the middle of the locking sleeve 122, and an adsorption groove 1222 is provided at the first end of the locking sleeve 122 in the first direction X. The adsorption groove 1222 is used for vacuum adsorbing the connecting piece. Therefore, the connecting piece can be vacuum adsorbed in the locking sleeve 122, and under the limiting action of the adsorption groove 1222, the connecting piece will not change its relative position due to gravity during fixation, and the axis line of the connecting piece and the axis of the locking sleeve 122 are always in the same straight line, avoiding the deviation of the connecting piece.

[0069] In summary, when the locking mechanism provided by the embodiments of the present utility model locks the connecting piece, the clamping jaw 121 can be used to limit the connecting piece, and then the connecting piece can be vacuum adsorbed through the adsorption groove 1222. And through the limiting connection of the adsorption groove 1222, the axis line of the connecting piece and the axis of the locking sleeve 122 are always in the same straight line. During the process of the electric screwdriver 11 driving the locking sleeve 122 to rotate, the connecting piece will not deviate in position, thereby ensuring the locking yield and locking efficiency of the locking mechanism for the connecting piece.

[0070] In a second aspect, the embodiments of the present utility model further provide a locking device, which includes a manipulator 2 and the locking mechanism 1 of any of the above embodiments; the manipulator 2 is connected to the locking mechanism 1 and is used to drive the locking mechanism 1 to move in any one of the first direction X, the second direction Y, and the third direction Z.

[0071] In this embodiment, the manipulator 2 can drive the locking mechanism 1 to move in any one of the first direction X, the second direction Y, and the third direction Z, so that the locking angle and the locking range of the locking mechanism 1 are not limited. In addition, since the locking mechanism 1 provided in the embodiment of the present invention can limit the connecting member by the clamping jaw 121 when locking the connecting member, and then vacuum adsorb the connecting member through the adsorption groove 1222, the axis of the connecting member and the axis of the locking sleeve 122 are always on the same straight line. During the process of the electric screwdriver 11 driving the locking sleeve 122 to rotate, the connecting member will not shift in position, thereby ensuring the locking yield rate of the locking mechanism 1 for the connecting member. Therefore, when the locking device includes the locking mechanism 1, the locking yield rate and the locking efficiency of the locking device can also be improved.

[0072] Further, in some embodiments, the locking device further includes a mounting bracket 3; the mounting bracket 3 includes a first plate 31, a second plate 32, and a third plate 33. The first plate 31 and the third plate 33 both extend along the third direction Z, the second plate 32 extends along the first direction X, the first plate 31 is installed at one end of the second plate 32 in the first direction X, and the third plate 33 is installed at the other end of the second plate 32 in the first direction X. The electric screwdriver 11 is installed on the first plate 31, and the manipulator 2 is installed on the third plate 33.

[0073] In this embodiment, since the first plate 31 is installed at one end of the second plate 32 in the first direction X, and the third plate 33 is installed at the other end of the second plate 32 in the first direction X. The electric screwdriver 11 is installed on the first plate 31, so the coaxiality between the electric screwdriver 11 and the locking sleeve 122 in the first direction X can be ensured. In addition, since the first plate 31 and the third plate 33 both extend along the third direction Z, the second plate 32 extends along the first direction X, the first plate 31 is installed at one end of the second plate 32 in the first direction X, the third plate 33 is installed at the other end of the second plate 32 in the first direction X, the electric screwdriver 11 is installed on the first plate 31, and the manipulator 2 is installed on the third plate 33, the installation of the electric screwdriver 11 and the manipulator 2 can be realized by one mounting bracket 3. While facilitating the installation and saving the manufacturing cost of the locking device, the structure of the entire locking device can be made more compact.

[0074] Further, in some embodiments, the electric screwdriver 11 includes a connecting shaft 111 and a connector 112; a limiting hole is installed on the second plate 32, and the axis of the limiting hole extends along the first direction X; the connecting shaft 111 passes through the limiting hole and is connected to the connector 112, and the connector 112 is slidably connected to the second plate 32.

[0075] It should be noted that a limit hole can be opened on the first plate 31, and the axis of the first mounting hole is coaxial with the axis of the electric screwdriver 11, so that the electric screwdriver 11 is installed in the limit hole, thereby ensuring the coaxiality between the electric screwdriver 11 and the locking sleeve 122 in the first direction X. In addition, an installation hole can also be opened on the third plate 33, and the axis of the installation hole is parallel to the axis of the electric screwdriver 11, so that the manipulator 2 is installed in the installation hole. The connector 112 and the manipulator 2 are respectively connected to two surfaces of the second plate 32 in the third direction Z. While providing support for the manipulator 2 through the second plate 32, it is convenient to limit the connector 112 in the first direction X through the second plate 32. In addition, it should be noted that the connector 112 can be connected through a linear sliding mechanism such as a slide rail structure or a motor lead screw structure, and the embodiment of the present invention does not limit this.

[0076] Further, in some embodiments, the locking device further includes a linear guide rail structure 4, and the electric screwdriver 11 further includes a connector 112; the linear guide rail structure 4 is installed in the direction of the second plate 32 facing the connecting shaft 111, and the connector 112 is slidably connected to the linear guide rail structure 4, wherein the linear guide rail structure 4 slides along the first direction X. In this way, by means of the sliding of the linear guide rail structure 4, the locking sleeve 122 connected to the connector 112 can move along the first direction X, thereby facilitating the locking mechanism 1 to approach and move away from the connecting member.

[0077] Further, in some embodiments, the locking device further includes a photographing assembly 5; the photographing assembly 5 is electrically connected to the manipulator 2, and the photographing assembly 5 is used to obtain the position information of the connecting member.

[0078] In this embodiment, when it is necessary to lock the connecting member, the position information of the connecting member can be obtained by the photographing assembly 5 first, and then the manipulator 2 drives the locking mechanism 1 to move to the corresponding position of the connecting member. Then, the clamping jaw 121 moves relative to the locking sleeve 122 in the direction close to the electric screwdriver 11 until the first end of the locking sleeve 122 is clamped in the clamping hole 1213, so that the position of the connecting member and the locking mechanism 1 is fixed. Then, the locking is performed through the locking mechanism 1. In this way, throughout the locking process, not only can an automated locking process be realized, but the entire process is safe and controllable, and the accuracy is also controllable. Therefore, the locking efficiency and the locking yield rate of the locking device can be improved.
