[0052] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0053] Reference below Figure 1-Figure 4 A screw locking device according to an embodiment of the present application is described.

[0054] Reference Figures 1 to 3 The screw locking device 100 includes a base, a first mounting portion 120 , a second mounting portion 130 , a plurality of electric screwdriver modules 140 , a first driving component 150 and a second driving component 160 .

[0055] The first mounting portion 120 is slidably mounted on the machine base in the vertical direction. This allows the first mounting portion 120 to have a larger range of movement in the vertical direction, which is convenient for height adjustment or adapting to different working conditions. In addition, the vertically movable installation method can more effectively utilize space and reduce the reliance on additional working space.

[0056] It should be noted that there are many ways to achieve the first mounting portion 120 being slidably mounted on the machine base in the up-down direction. For example, in one embodiment, the machine base may be designed with a slide rail 171, and the first mounting portion 120 is provided with a slider that cooperates with the slide rail 171. By sliding the slider on the slide rail 171, the first mounting portion 120 can be moved up and down relative to the machine base. In another embodiment, the first mounting portion 120 can be connected to the machine base through a ball screw, so that the up-down movement of the first mounting portion 120 can be accurately controlled. Specifically, the present application does not limit the way in which the first mounting portion 120 is slidably mounted on the machine base in the up-down direction.

[0057] The second mounting portion 130 is rotatably mounted on the first mounting portion 120 via a rotation axis a extending in the vertical direction. Thus, this mounting method provides the second mounting portion 130 with the freedom to rotate around the axis of the rotation axis a, so that it can be flexibly moved or adjusted in multiple directions. The rotating mounting method can more effectively utilize space and reduce the reliance on additional working space.

[0058] A plurality of electric screwdriver modules 140 are installed on the second mounting portion 130, and the plurality of electric screwdriver modules 140 are arranged at intervals along the circumference of the rotation axis a. In this way, the setting of the plurality of electric screwdriver modules 140 can perform multiple operations at the same time, thereby improving work efficiency. The circumferential arrangement of the electric screwdriver modules 140 along the rotation axis a can make the load distribution more balanced and improve stability. In addition, the plurality of electric screwdriver modules 140 can rotate with the second mounting portion 130, so that a plurality of electric screwdriver modules can be selected and used in sequence according to different operation requirements, thereby improving the flexibility of the equipment. If a certain electric screwdriver module 140 fails or wears out, it can be easily replaced or repaired without affecting the normal use of other electric screwdriver modules 140. The plurality of electric screwdriver modules 140 are arranged at intervals along the circumference of the rotation axis a, so that the plurality of electric screwdriver modules 140 can be installed more compactly, thereby saving space. This method allows different electric screwdriver modules 140 to be selected and replaced according to different needs and operation requirements, thereby facilitating modular design and production. The provision of multiple electric screwdriver modules 140 can provide more positioning and adjustment options, making the operation more precise and reliable.

[0059] It should be noted that the technology of the electric screwdriver module is mature, and the present application does not limit the specific structure of the electric screwdriver module. In addition, the working principle of the electric screwdriver module is to tighten the screws using an electric screwdriver or an electric screwdriver. The internal structure of the electric screwdriver module mainly includes a motor and a transmission system, wherein the motor provides power, and the transmission system transmits the power to the screwdriver head, and tightens the screws by rotating the screwdriver head. When the motor is powered on, the transmission system starts to work, driving the screwdriver head to rotate, thereby tightening the screws.

[0060] The first drive assembly 150 is installed on the machine base, and the first drive assembly 150 is used to drive the first mounting part 120 to move. In this way, the first drive assembly 150 can enable the first mounting part 120 to achieve automatic or intelligent movement, reduce manual intervention, and improve work efficiency and quality. The first drive assembly 150 can accurately control the moving position and speed of the first mounting part 120 to achieve high-precision operation. By driving the first mounting part 120 to move through the first drive assembly 150, the labor intensity of manual operation can be reduced. Automated and intelligent operation can reduce the risk of manual operation and improve the safety of operation. The stability and reliability of the first drive assembly 150 are usually higher than manual operation, which can ensure the continuity and stability of the operation. By using the first drive assembly 150, the dependence on manual operation can be reduced and human resources can be saved.

[0061] The second drive assembly 160 is mounted on the first mounting portion 120, and the second drive assembly 160 is used to drive the second mounting portion 130 to rotate. In this way, the second drive assembly 160 can enable the second mounting portion 130 to rotate flexibly to meet the operation requirements of various angles and orientations. The second drive assembly 160 can accurately control the rotation angle and speed of the second mounting portion 130 to achieve high-precision operation. The stability and reliability of the second drive assembly 160 are usually higher than manual operation, which can ensure the stability and accuracy of the rotation. By using the second drive assembly 160, the dependence on manual operation can be reduced and human resources can be saved.

[0062] According to the screw locking device 100 of the present application, the screw locking device 100 combines the design of sliding, rotating and multiple electric modularization, can quickly and accurately complete the screw locking operation, improve work efficiency, and at the same time improve the customer's production line yield and production capacity. The first drive assembly 150 and the second drive assembly 160 can accurately control the first mounting portion 120 and the second mounting portion 130 to ensure the accurate position and angle of the screw locking. The screw locking device 100 can realize automated and intelligent screw locking operations, reduce manual intervention, and improve the consistency and reliability of the operation. The circumferential spacing of multiple electric screwdriver modules 140 along the rotating shaft a makes the layout reasonable and compact, so that the occupied space of the screw locking device 100 can be reduced. The design of the mechanism makes the operation simple, the adjustment is fast, and the difficulty of operation is reduced. The design of the rotating shaft a and the stability of the second drive assembly 160 can ensure the stability and accuracy of the screw locking process.

[0063] Reference Figures 1 to 3 In one embodiment, the first drive assembly 150 includes a first drive motor 151 and a transmission mechanism 152. The first drive motor 151 has a first drive shaft. The transmission mechanism 152 is connected to the first drive shaft and the first mounting portion 120. The transmission mechanism 152 is used to convert the rotation of the first drive shaft into the sliding of the first mounting portion 120 in the up and down direction. In this way, the transmission mechanism 152 can accurately convert the rotation of the first drive shaft into the up and down sliding of the first mounting portion 120, ensuring high-precision position control. In addition, the stability and accuracy of the sliding of the first mounting portion 120 can be ensured. The use of the first drive motor 151 and the transmission mechanism 152 can reduce the manufacturing cost and maintenance cost of the equipment.

[0064] It should be noted that there are various transmission mechanisms 152 for converting the rotation of the first drive shaft into the sliding of the first mounting portion 120 in the up-down direction. For example, the transmission mechanism 152 includes a ball screw, a belt drive, a chain drive, a gear rack, or a screw drive. Since the technologies of ball screws, belt drives, chain drives, gear racks, and screw drives are mature, this application will not elaborate on them.

[0065] In one embodiment, the first drive motor 151 includes a servo motor, so that the servo motor can achieve high-precision position, speed and torque control, so that the first mounting part 120 has higher accuracy and stability during operation. The servo motor has the characteristics of fast response, can reach the set value in a shorter time, and quickly follow the command changes, thereby improving the dynamic performance of the first mounting part 120. The servo motor can achieve speed control in a larger range, meet the speed requirements of different working stages, and improve work efficiency. The servo motor runs smoothly, with less noise and vibration, which can improve the comfort of the working environment. The servo motor can automatically adjust the power and speed according to actual needs, avoid unnecessary energy waste, and improve work efficiency. The servo motor has high reliability and stability, can run stably for a long time, and reduce the probability of maintenance and failure. The servo motor is easy to integrate with the control system, convenient for installation and maintenance, and reduces overall costs.

[0066] Reference Figures 1 to 3 In one embodiment, each electric screwdriver module 140 is slidably mounted on the second mounting portion 130 in the up-down direction through a sliding structure 170, and a buffer 180 is provided between each electric screwdriver module 140 and the second mounting portion 130. The buffer 180 is used to apply a downward elastic force when the electric screwdriver module 140 slides upward. In this way, the buffer 180 can provide a certain elastic force, so that the electric screwdriver module 140 is more stable during the sliding process, reduce vibration and shaking, and improve the stability of the operation. When the electric screwdriver module 140 is subjected to external impact, the buffer 180 can absorb part of the energy, reduce the impact on the electric screwdriver module 140 and the second mounting portion 130, and improve the impact resistance of the equipment. By reducing the vibration and impact of the electric screwdriver module 140 during the sliding process, the service life of the electric screwdriver module 140 and the second mounting portion 130 and other components can be extended. Due to the effect of the buffer 180, the installation position of the electric screwdriver module 140 can be easily adjusted, and the damage to the components can also be reduced during the maintenance process. The buffer 180 can effectively reduce the noise during the sliding process and improve the working environment. The setting of the buffer 180 can also reduce the damage to the point-locking workpiece when the electric screwdriver module 140 moves downward.

[0067] Reference Figure 3 and Figure 4In one embodiment, each sliding structure 170 includes a slide rail 171 extending in the vertical direction and a slide seat 172 slidably matched with the slide rail 171. The slide rail 171 is connected to the second mounting portion 130, and the slide seat 172 is connected to the electric screwdriver module 140. In this way, the cooperation of the slide rail 171 and the slide seat 172 provides a clear guide for the electric screwdriver module 140, ensuring that the electric screwdriver module 140 slides accurately in the vertical direction. The combined structure of the slide rail 171 and the slide seat 172 increases the sliding stability of the electric screwdriver module 140 and reduces the deviation or instability caused by vibration or other factors. The design of the sliding structure 170 can reduce the required space and make the equipment layout more compact. The open design of the slide rail 171 and the slide seat 172 makes cleaning and maintenance easier and reduces maintenance costs. The design structure of the sliding structure 170 is simple and low in cost, while meeting the requirements of high precision and stability, and has a high cost performance.

[0068] Reference Figures 1 to 3 In one embodiment, the second mounting portion 130 is also equipped with a plurality of limiting structures, and the plurality of limiting structures are arranged one by one with the plurality of electric screwdriver modules 140. Each limiting structure is used to limit the movable travel of the corresponding sliding seat 172 in the up and down directions. In this way, the limiting structure can limit the maximum upward and downward travel of the electric screwdriver module 140, avoid overshoot or undershoot, and ensure the accuracy of the operation. By limiting the travel of the electric screwdriver module 140, the time for adjustment and calibration can be reduced, and the overall work efficiency can be improved. The limiting structure can prevent the electric screwdriver module 140 from exceeding the set travel range, thereby avoiding unnecessary damage or wear to the equipment. For the operator, the use of the limiting structure can simplify the operating steps and reduce the possibility of error. By limiting the travel of the electric screwdriver module 140, the safety of the use of the screw locking device 100 can be improved. Due to the existence of the limiting structure, the travel of the electric screwdriver module 140 is consistent during each operation, which improves the repeatability of the operation. The design of the limiting structure is usually simpler and cheaper than a complete travel limiter, which helps to reduce costs. The design of the limiting structure can adapt to different working environments and working conditions and has good adaptability.

[0069] Reference Figure 1 , Figure 2 and Figure 4In one embodiment, each limiting structure includes a first stopper 191 and a second stopper 192 respectively arranged at both ends of the corresponding slide rail 171. The first stopper 191 and the second stopper 192 are arranged opposite to each other. In the upward movement of the sliding seat 172, the upper end of the sliding seat 172 is suitable for abutting against the first stopper 191. In the downward movement of the sliding seat 172, the lower end of the sliding seat 172 is suitable for abutting against the second stopper 192. In this way, the first stopper 191 and the second stopper 192 provide a clear limiting point for the sliding seat 172 to ensure that the range of movement of the sliding seat 172 in the up and down directions is limited. Due to the existence of the limiting structure, the movement of the electric screwdriver module 140 in the up and down directions is more stable, reducing vibration or shaking. The first stopper 191 and the second stopper 192 respectively arranged at both ends of the slide rail 171 are compact in design and can effectively save space. The limiting structure is simple in design, durable and highly reliable. This limiting structure is usually low in cost and can meet the needs of actual work. The open design of the limiting structure makes cleaning and maintenance easier. This limiting structure can be easily integrated with the slide rail 171 and the sliding seat 172 to form a complete sliding system.

[0070] Reference Figure 2 In one embodiment, the second stopper 192 includes a second stopper 1921 and an adjusting portion 1922. The second stopper 1921 is mounted on the second mounting portion 130, and the adjusting portion 1922 is movably mounted on the second stopper 1921, so that the adjusting portion 1922 can be adjusted in the vertical direction. The upper end of the adjusting portion 1922 is used to abut against the lower end of the sliding seat 172. In this way, the existence of the adjusting portion 1922 makes the second stopper 192 highly flexible and can adjust its position according to different electric screwdriver modules 140 or operation requirements. The design of the adjusting portion 1922 allows the operator to easily adjust its position without the need for complex operations or the use of tools. Due to the adjustability of the adjusting portion 1922, the elastic force of the buffer 180 can be adjusted, and the sliding of the electric screwdriver module 140 can be more accurately controlled to ensure that it works within the expected range, and the wear of the electric screwdriver module 140 on the workpiece to be locked can be reduced, thereby extending the service life of the electric screwdriver module 140 and the workpiece to be locked. Due to the existence of the adjustment part 1922, the operator can quickly adjust the stroke of the electric screwdriver module 140, thereby improving the overall work efficiency.

[0071] Reference Figure 3 and Figure 4In one embodiment, the first stopper 191 is provided with a guide hole 1911 in the vertical direction, and a guide rod 1721 is provided at the upper end of the sliding seat 172. The guide rod 1721 is extended in the vertical direction, and the guide rod 1721 is inserted into the guide hole 1911 in the vertical direction. In this way, the design of the guide hole 1911 and the guide rod 1721 provides a clear guide for the sliding seat 172, ensuring that the movement of the sliding seat 172 in the vertical direction is more accurate and stable. The matching design of the guide rod 1721 and the guide hole 1911 makes the assembly of the sliding seat 172 simpler and more convenient. The design of the guide hole 1911 and the guide rod 1721 helps to improve the sliding accuracy of the electric screwdriver module 140 and reduce errors. The design of the guide hole 1911 and the guide rod 1721 is compact, which can effectively save space. This design makes cleaning and maintenance easier. The precise guide design can reduce the time for adjustment and calibration, thereby improving the overall work efficiency. This design has a simple structure and low cost, while meeting the requirements of high precision and stability.

[0072] Reference Figure 3 and Figure 4 In one embodiment, the buffer 180 includes a plurality of springs, and the plurality of springs are arranged one by one with the plurality of sliding seats 172. Each spring is between the corresponding sliding seat 172 and the first stopper 191, and is mounted on the guide rod 1721. In this way, the spring as a buffer 180 can effectively absorb and disperse the impact force, and reduce the impact and vibration on the electric screwdriver module 140 or the workpiece to be tightened and locked. The compression and extension range of the spring is large, and can meet the requirements of different strokes and loads. The stiffness and compression of the spring can be adjusted as needed to meet specific buffering requirements. Due to the supporting effect of the spring, the sliding seat 172 can be kept stable and not prone to tilting or shaking. Appropriate buffering can reduce the wear of the sliding seat 172 and other related components, thereby extending their service life. As a common buffer 180, the spring has a low cost and can meet the requirements of buffering and stability. The spring has a simple structure, occupies a small space, and is easy to install and maintain. The buffering effect of the spring can reduce the risk of accidental injury that the operator may face during operation. The stable slide base 172 can reduce the time for adjustment and calibration, thereby improving the overall work efficiency.

In this way, the design of the hollow rotating platform 101 allows the first mounting portion 120 and the second mounting portion 130 to rotate relative to each other, thereby increasing the flexibility of the device. Through the second driving assembly 160, the operator can conveniently control the rotation of the hollow rotating platform 101, thereby simplifying the operation process. The rotation of the hollow rotating platform 101 can be completed quickly, reducing the time for adjustment and calibration, and improving the overall work efficiency. The design of the hollow rotating platform 101 is compact, which can effectively save space. The hollow rotating platform 101 and the second driving assembly 160 can be conveniently integrated with the first mounting portion 120 and the second mounting portion 130 to form a complete system. By controlling the rotation of the hollow rotating platform 101 through the second drive assembly 160, the risk of accidental injury that the operator may face during operation can be reduced. This design has a simple structure and low cost, while meeting the requirements of high precision and stability. The design of the hollow rotating platform 101 makes cleaning and maintenance easier.

[0074] Reference Figure 1 and Figure 2In one embodiment, the second mounting portion 130 includes a connecting portion 131 and a movable mounting portion 132. The connecting portion 131 is connected to the rotation axis a. The connecting portion 131 has a first end face 1311 disposed downward. The movable mounting portion 132 is movably connected to the connecting portion 131 in the up-down direction. The movable mounting portion 132 has a second end face 1321 disposed upward. The second end face 1321 is opposite to the first end face 1311 and is disposed at intervals. The screw locking device 100 also includes a pressure sensor 102. The pressure sensor 102 is disposed between the second end face 1321 and the first end face 1311. In this way, the design of the connecting portion 131 and the movable mounting portion 132 enables the second mounting portion 130 to remain stable and not prone to shaking or moving. The design of the movable mounting portion 132 enables the second mounting portion 130 to be adjusted as needed to adapt to different work requirements. The presence of the pressure sensor 102 can monitor the force of the screw locking in real time, avoid overload or excessive pressure, and improve the safety of operation. The force of screw locking can be precisely controlled by the pressure sensor 102 to ensure the accuracy and reliability of the locking. The real-time monitoring function of the pressure sensor 102 can reduce the number of manual inspections and adjustments, thereby improving overall work efficiency. The use of pressure sensors 102 can reduce labor costs and material costs while improving work efficiency. Proper monitoring and control can reduce wear on related components, thereby extending the service life of the equipment. The setting of the pressure sensor 102 can monitor in real time and detect potential problems or failures in a timely manner, thereby reducing the failure rate of the equipment.
