[0022] This utility model proposes a locking device 1000.

[0023] Please see Figure 1 In one embodiment of the present invention, the locking device 1000 includes a base 1, a rotating mechanism 2 and an electric screwdriver mechanism 3. The rotating mechanism 2 is disposed on the base 1. The electric screwdriver mechanism 3 is located at the driving end of the rotating mechanism 2 and is connected to the rotating mechanism 2 in a transmission manner. The rotating mechanism 2 can drive the electric screwdriver mechanism 3 to rotate, thereby changing the posture of the electric screwdriver mechanism 3.

[0024] In this embodiment, the locking device 1000 can be applied to industrial scenarios where fasteners such as screws and nuts need to be tightened in electronic products such as subwoofer speakers and mobile phones. Combined with... Figure 1It should be noted that the base 1 provides a stable mounting platform for the rotating mechanism 2 and the electric screwdriver mechanism 3, ensuring that the fastening accuracy is not affected by shaking or instability during operation. It is understood that the base 1 is a sheet metal component. The rotating mechanism 2 drives the electric screwdriver mechanism 3 to rotate, thereby changing its posture. By controlling the rotation angle and direction, the electric screwdriver mechanism 3 can quickly align to different fastening positions. The electric screwdriver mechanism 3 performs the fastening operation and includes two electric screwdriver assemblies 32. Through the rotational movement of the electric screwdriver assemblies 32, the screws are tightened onto the workpiece, completing the fastening task. It should be noted that the connection between the rotating mechanism 2 and the electric screwdriver mechanism 3 includes, but is not limited to, mechanical connections and indirect transmission connections. In one embodiment, a motor is mounted on the base 1, and the motor's output shaft is connected to a small gear via a coupling. The small gear meshes with a large gear on the rotating mechanism 2, and the large gear is mounted on the rotating shaft of the rotating mechanism 2. The electric screwdriver mechanism 3 is fixed to the drive end of the rotating mechanism 2, and its drive shaft is connected to the rotating shaft via a coupling. The rotation of the motor is transmitted to the rotating shaft via a pinion and a gear, driving the electric screwdriver mechanism 3 to rotate, thereby changing its posture. In another embodiment, the output shaft of the motor is connected to the rotating shaft of the rotating mechanism 2 via a pulley. A driving pulley is mounted on the output shaft of the motor, and a driven pulley is mounted on the rotating shaft; the two pulleys are connected by a belt. The electric screwdriver mechanism 3 is fixed to the drive end of the rotating mechanism 2 by a bracket, and its posture adjustment is achieved by the rotation of the rotating shaft. When the motor is running, its rotation is transmitted to the rotating shaft via the belt, driving the electric screwdriver mechanism 3 to rotate.

[0025] The screw fastening device 1000 provided by this utility model, through the combined design of a rotating mechanism 2 and an electric screwdriver mechanism 3, solves the problem of limited fastening angle in existing screw fastening devices 1000 under complex working conditions. Specifically, the rotating mechanism 2 is mounted on the base 1, and the electric screwdriver mechanism 3 is located at the drive end of the rotating mechanism 2 and is connected to it via transmission. This allows the electric screwdriver mechanism 3 to rotate 360 ​​degrees under the drive of the rotating mechanism 2, thereby flexibly adjusting the fastening angle according to actual working conditions and adapting to different screw installation positions in confined spaces or complex assembly environments. The base 1 provides a stable support foundation for the entire device, ensuring the stability of the rotating mechanism 2 and the electric screwdriver mechanism 3 during operation. The design of the rotating mechanism 2 enables the electric screwdriver mechanism 3 to achieve omnidirectional rotation, greatly improving the flexibility and adaptability of the device. As the part that actually performs the fastening operation, the electric screwdriver mechanism 3, through its transmission connection with the rotating mechanism 2, can quickly and accurately adjust to the required angle under its drive, thereby enabling screw fastening from different directions. The above configuration allows the screw fastening device 1000 to easily handle various complex working conditions without frequent adjustments to the device position or manual adjustment of the screw direction, greatly improving work efficiency. Simultaneously, because the electric screwdriver mechanism 3 can be adjusted according to the actual position and direction of the screw, the fastening quality is significantly improved, reducing the risk of fastening failure or component damage due to improper angles. Its versatility and applicability are also greatly expanded, meeting the screw fastening needs of various products and application scenarios, and reducing equipment procurement costs and management complexity for enterprises.

[0026] In one embodiment of the present invention, the rotating mechanism 2 includes a first driving member 21, a rotating bearing 22, and an origin sensor 23. The driving shaft of the first driving member 21 passes through the base 1 and is connected to the rotating bearing 22. The origin sensor 23 is located on one side of the base 1 and close to the rotating bearing 22. The origin sensor 23 is configured to detect the rotation angle of the rotating bearing 22.

(Combined) Figure 5The origin sensor 23 is used to detect the rotation angle of the rotary bearing 22. The type of origin sensor 23 includes, but is not limited to, photoelectric sensors and magnetic sensors. The origin sensor 23 is mounted on one side of the base 1 via bolt connection, snap-fit, or other means; this is not limited here. In one embodiment, the origin sensor 23 is in the form of a photoelectric sensor, with a ring of scale lines or reflective marks on the outer ring of the rotary bearing 22. The photoelectric sensor detects changes in the position of the marks by emitting or receiving light. In another embodiment, the origin sensor 23 is in the form of a magnetic sensor, with a ring of magnetic marks on the outer ring of the rotary bearing 22. The magnetic sensor determines the rotation angle by detecting changes in the magnetic field.

[0028] In one embodiment of the present invention, the rotating mechanism 2 further includes a reducer, which is sleeved on the drive shaft of the first driving member 21, and a first coupling is provided between the drive shaft of the first driving member 21 and the rotating bearing 22.

[0029] In this embodiment, to further improve torque output, the reducer lowers the motor's output speed while simultaneously increasing torque output. The reducer is positioned between the first drive member 21 and the rotary bearing 22. The type of reducer includes, but is not limited to, planetary gear reducers and worm gear reducers; a planetary gear reducer is preferred here. Figure 4 The first coupling is used to ensure the continuity and stability of the transmission. The type of the first coupling includes, but is not limited to, flexible couplings and diaphragm couplings, with diaphragm couplings being preferred here.

[0030] In one embodiment of the present invention, the electric screwdriver mechanism 3 includes a connector 31 and two electric screwdriver assemblies 32. One end of the connector 31 is connected to the rotary bearing 22 of the rotary mechanism 2, and an electric screwdriver assembly 32 is connected to each of the opposite sides of the connector 31.

[0031] In this embodiment, in order to improve the locking efficiency, combined with Figure 2 and Figure 3 It should be noted that the connector 31 is used to connect the rotary bearing 22 and the electric screwdriver assembly 32. The drive shaft of the first drive member 21 of the rotating mechanism 2 extends into the connector 31, allowing the connector 31 to rotate under the drive of the first drive member 21, thereby driving the two electric screwdriver assemblies 32 mounted on the connector 31 to rotate. The electric screwdriver assembly 32 is used to fasten screws, nuts, and other fasteners. The connection between the connector 31 and the electric screwdriver assembly 32 includes, but is not limited to, bolted connections, sliding connections, and snap-fit ​​connections.

[0032] In one embodiment of the present invention, each electric screwdriver assembly 32 includes a fixing member 321, a second driving member 322, and an electric screwdriver bit 323. The fixing member 321 is disposed on the connecting member 31, and the electric screwdriver bit 323 and the second driving member 322 are both disposed on the fixing member 321. The second driving member 322 is connected to the electric screwdriver bit 323 in a transmission manner.

[0033] In this embodiment, combined with Figure 2 and Figure 3 The fixing member 321 provides stable mechanical support for the electric screwdriver bit 323 and the second drive member 322, ensuring the stability of the electric screwdriver bit 323 and the second drive member 322 during operation. The fixing member 321 is in the form of a plate and can be fixed to the connecting member 31 by bolts, rivets, or other means. The type of the second drive member 322 includes, but is not limited to, a servo motor, a stepper motor, or a cylinder; a cylinder is preferred here. The electric screwdriver bit 323 is used to perform the locking operation. The second drive member 322 can be fixed to the fixing member 321 by bolts, screws, or other fasteners. The driving end of the second drive member 322 has a first connecting plate, one end of which is sleeved onto the electric screwdriver bit 323. Thus, under the drive of the second drive member 322, the electric screwdriver bit 323 moves along... Figure 3 Move downwards in the direction of the middle arrow to lock.

[0034] In one embodiment of the present invention, each electric screwdriver assembly 32 further includes an elastic element 324, which is disposed between the fixing element 321 and the second driving element 322.

[0035] In this embodiment, combined with Figure 3 To effectively absorb the impact force generated during the fastening process and reduce the impact of the electric screwdriver bit 323 on fasteners such as screws and nuts, thereby extending the service life of the equipment, the elastic element 324 includes, but is not limited to, springs, rubber pads, etc., with a spring being preferred here. It should be noted that the second driving element 322 is mounted on the fixing element 321 via a second connecting plate. In the previous embodiment, the elastic element 324 is positioned between the first and second connecting plates. Thus, under the action of the second driving element 322, the presence of the elastic element 324 reduces the direct impact of the electric screwdriver bit 323 on fasteners such as screws and nuts.

[0036] In one embodiment of the present invention, the electric screwdriver mechanism 3 further includes two pitch adjustment components 33. Each pitch adjustment component 33 includes a third driving member 331 and a guide block 332. The third driving member 331 is disposed on the connector 31. The driving end of the third driving member 331 is connected to the guide block 332. The guide block 332 is connected to the electric screwdriver assembly 32. The third driving member 331 can drive the guide block 332 and the electric screwdriver assembly 32 to move along the extension direction of the connector 31.

[0037] In this embodiment, combined with Figure 2It should be noted that the pitch adjustment component 33 is used to achieve pitch variation. The type of the third drive component 331 includes, but is not limited to, stepper motors, servo motors, etc., with a servo motor being preferred here. It is understood that the third drive component 331 can be mounted on the connecting component 31 via bolts, snap-fit ​​connections, etc. The drive end of the third drive component 331 passes through the guide block 332, and the drive end of the third drive component 331 is equipped with a lead screw, which is fixed in the guide block 332 by a lead screw nut, thereby enabling the guide block 332 to move left and right. The guide block 332 is slidably connected to the connecting component 31, and the fixing component 321 of the electric screwdriver assembly 32 is mounted on the guide block 332 by bolts or other fasteners. The connecting component 31 has double guide rails along its extension direction, and two sliders are connected to the bottom of the guide block 332 respectively. The guide block 332 can move under the drive of the third drive component 331 by the two sliders slidingly connecting to the double guide rails. Furthermore, a pitch adjustment component 33 is provided on each of the opposite sides of the connector 31, and each pitch adjustment component 33 is connected to an electric screwdriver component 32. This not only enables the rotation of the electric screwdriver component 32, but also allows the electric screwdriver component 32 to move left and right along the extension direction of the connector 31. The pitch adjustment component 33 can automatically adjust the pitch within the range of 120-215mm, and the distance between the two electric screwdriver components 32 is adjusted by driving the electric screwdriver component 32 to move left and right through a servo motor and a lead screw.

[0038] In one embodiment of the present invention, each pitch adjustment component 33 further includes a second coupling 333 and a lead screw support 334. The second coupling 333 and the lead screw support 334 are sleeved on the driving end of the third driving member 331, and the second coupling 333 is located between the third driving member 331 and the lead screw support 334.

[0039] In this embodiment, combined with Figure 2 To further improve transmission accuracy, a second coupling 333 is provided at the drive end of the third drive member 331. The second coupling 333 ensures a precise connection between the third drive member 331 and the lead screw support 334, reducing transmission errors and improving the accuracy of position adjustment. The lead screw support 334 is sleeved on the drive end of the third drive member 331. The lead screw support 334 stably supports the lead screw through bearings or other support structures, ensuring that the lead screw maintains linear motion during operation and reducing transmission errors caused by lead screw bending or offset. The type of the second coupling 333 includes, but is not limited to, diaphragm couplings, flexible couplings, etc., and is not limited here. It can be understood that the third drive member 331 transmits power to the lead screw support 334 through the second coupling 333. The lead screw support 334 drives the lead screw to rotate, and the lead screw converts the rotational motion into linear motion through the nut pair, driving the guide block 332 to move along the extension direction of the connecting member 31.

[0040] In one embodiment of the present invention, the distance adjustment component 33 further includes at least one photoelectric sensor 335, and each photoelectric sensor 335 is spaced apart at one end of the connector 31 away from the rotating mechanism 2.

[0041] In this embodiment, combined with Figure 2 To further adjust the spacing, a photoelectric sensor 335 is installed at the end of the connecting member 31 away from the rotating mechanism 2. The number of photoelectric sensors 335 is not limited and can be set according to specific needs. The photoelectric sensor 335 is used to control the number of rotations of the third driving member 331, thereby controlling the adjusted spacing. It can be understood that, in combination with... Figure 2 There are four photoelectric sensors 335, with two photoelectric sensors 335 corresponding to one electric screwdriver assembly 32. The photoelectric sensors 335 detect the position of the electric screwdriver assembly 32 by emitting and receiving light. When the light is reflected or blocked by a reflective mark or obstruction on the electric screwdriver assembly 32, the photoelectric sensor 335 generates an electrical signal, which is transmitted to the control terminal of the entire locking device 1000, thereby limiting the number of turns of the third drive member 331.

[0042] In one embodiment of the present invention, the locking device 1000 further includes a fourth driving member, which is connected to the base 1 in a transmission manner.

[0043] In this embodiment, combined with Figure 1 Furthermore, to enhance the flexibility of the entire locking device 1000, a fourth driving component is provided at one end of the base 1. This fourth driving component can drive the base 1 to move in a certain direction, allowing the entire locking device 1000 to adjust its position over a wider range to accommodate workpieces of different sizes and shapes. The type of the fourth driving component includes, but is not limited to, motors, cylinders, etc., and is not specified here.
