The traditional distribution cabinet assembly process relies on manual screw fixing, which has many limitations. First, the efficiency of manual operation is relatively low, which is difficult to meet the needs of large-scale production. Secondly, due to the uncertainty of human factors, it is difficult to maintain consistency in the strength and quality of tightening screws, which may lead to the instability of the distribution cabinet structure and even affect its electrical performance.

Figure 1-Figure 10 Make a detailed description:

[0042] Embodiment 1:

[0043] The present invention discloses an industrial robot for assembling a power distribution cabinet, which is intended to improve the automation level and the efficiency of screw driving in the assembly process of the power distribution cabinet. The industrial robot comprises a carrier frame 1, a conveyor belt assembly 2, a clamping and fixing mechanism 3 and a screw driving mechanism 4, wherein:

[0044] The carrier frame 1 is arranged horizontally, and a mounting frame 11 is fixed on the top of the carrier frame 1 to provide a stable supporting platform for the robot;

[0045] The conveyor belt assembly 2 is horizontally arranged on the carrier frame 1, and is responsible for transporting the assembled but unscrewed distribution cabinets to ensure that the distribution cabinets move smoothly on the assembly line;

[0046] The clamping and fixing mechanism 3 is installed on the mounting frame 11 and is used to clamp and fix the power distribution cabinet on the conveyor belt assembly 2 to ensure the stability of the power distribution cabinet during the screwing process;

[0047] The screw driving mechanism 4 is used to drive screws on one side of the distribution cabinet. The screw driving mechanism 4 includes a mounting plate 41, a lifting assembly 42, two sets of screw driving assemblies 43, an adjusting member 44 for adjusting the distance between the two sets of screw driving assemblies 43, and a driving assembly 45. The mounting plate 41 is movably arranged in the mounting frame 11, the lifting assembly 42 is fixed on the mounting frame 11 and is used to control the lifting and lowering of the mounting plate 41 to adapt to the operation requirements of different heights. The two sets of screw driving assemblies 43 are symmetrically installed at the bottom of the mounting plate 41, the adjusting member 44 is installed on the mounting plate 41 and is used to adjust the distance between the two sets of screw driving assemblies 43 to adapt to distribution cabinets of different sizes, and at the same time to adapt to different punching positions on the distribution cabinet. The driving assembly 45 is used to drive the two sets of screw driving assemblies 43 to operate synchronously to ensure that the two sets of screw driving assemblies 43 tighten the screws with the same force, thereby improving the consistency and reliability of screw driving.

[0048] In the power distribution cabinet assembly type industrial robot of the present invention, the design of the conveyor belt assembly 2 is crucial for the smooth transportation of the power distribution cabinet. For details, please refer to Figure 2 , Figure 3 and Figure 5 The conveyor belt assembly 2 includes a plurality of rotating rollers 21 which are distributed in an array and rotatably mounted at both ends on the carrier frame 1. An integrated conveyor belt 22 is sleeved on the plurality of rotating rollers 21. The conveyor belt 22 constitutes a channel for transporting the distribution cabinet. The distribution cabinet is placed on the top side of the conveyor belt 22 so as to move on the production line.

[0049] In order to drive the operation of the conveyor belt 22, a sprocket 23 is fixedly sleeved on one end of the same side of several rotating rollers 21, and an integrated chain 231 is sleeved on several sprockets 23. The conveyor belt assembly 2 also includes a servo motor 24 arranged under the carrier frame 1. A driving wheel 25 is fixedly sleeved on the output shaft of the servo motor 24. A driven wheel 26 is fixedly sleeved on the other end of one of the rotating rollers 21 at the edge. An integrated transmission belt 27 is sleeved between the driven wheel 26 and the driving wheel 25. The driving wheel 25 is controlled to rotate by the servo motor 24. Under the linkage of the transmission belt 27 and the driven wheel 26, one of the rotating rollers 21 at the edge is driven to rotate, so that the conveyor belt 22 is operated and the power distribution cabinet is driven to move.

[0050] Through the precise control of the servo motor 24, the speed and position of the conveyor belt 22 can be accurately adjusted to ensure the smooth and accurate transportation of the distribution cabinet on the production line. This design not only improves the efficiency of the distribution cabinet transportation, but also provides a stable working platform for subsequent screw driving operations. The use of the servo motor 24 enables the conveyor belt assembly 2 to flexibly adapt to different production speeds and rhythms, thereby enhancing the adaptability and flexibility of the entire robot system.

[0051] In this embodiment, the design of the clamping and fixing mechanism 3 is crucial to ensure the stability and accuracy of the power distribution cabinet during the screwing process. Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The clamping and fixing mechanism 3 is composed of two symmetrically arranged clamping members, which are respectively mounted on the two opposite ends of the mounting frame 11 along the length direction of the conveyor belt 22, thereby ensuring uniform clamping of the distribution cabinet on the conveyor belt 22;

[0052] The clamping member includes a bearing plate 31 installed on the mounting frame 11, and a vertical electric push rod 1 32 is installed on the bearing plate 31, and the output end of the electric push rod 1 32 is downward and fixed with a horizontal electric push rod 2 33 through a fixing plate, and the output ends of the electric push rods 2 33 in the two clamping members are opposite, and a clamping plate 34 is installed on the output end of the electric push rods 2 33. Through the operation of the two electric push rods 2 33, the two clamping plates 34 are close to each other to clamp and fix the power distribution cabinet, ensuring stability during the screwing process, and the setting of the electric push rod 1 32 can adjust the height of the clamping plate 34, which can be adjusted according to the type of the power distribution cabinet;

[0053] Through this design, the clamping and fixing mechanism 3 can accurately control the clamping force and position, ensuring the stability of the distribution cabinet during the screw driving process, while also improving the flexibility and adaptability of the operation.

[0054] The two support plates 31 are connected to the two support rails 31 and the two support rails 31 are connected to the two support rails 31 by a screw thread mechanism 35. The two support rails 31 are connected to the two support rails 31 by a screw thread mechanism 35. The two support rails 31 are connected to the two support rails 31 and the two support rails 31 are connected to the two support rails 31 by a screw thread mechanism 35.

[0055] Furthermore, a servo motor three 331 is fixed on the output end of the electric push rod two 33, the output shaft of the servo motor three 331 faces away from the electric push rod two 33 and the clamping plate 34 is fixed on the output shaft of the servo motor three 331. The advantage of setting the servo motor three 331 is that when the screwing on one side of the distribution cabinet is completed, the electric push rod one 32 lifts the distribution cabinet to a certain height through the clamping plate 34, and then the servo motor three 331 drives the clamping plate 34 to rotate, thereby rotating the distribution cabinet so that the side without screws faces upward, and then the electric push rod one 32 controls the clamping plate 34 to descend, and the distribution cabinet is stably placed on the conveyor belt 22, and the screwing operation can be performed on the other side.

[0056] In the power distribution cabinet assembly type industrial robot of the present invention, the design of the lifting assembly 42 is crucial to achieve accurate positioning and height adjustment of the screw driving mechanism 4, see Figure 2 , Figure 6 and Figure 8 The lifting assembly 42 includes an electric push rod 3 421 fixed to the top of the mounting frame 11 and with the output end pointing vertically downward. The middle of the top side of the mounting plate 41 is fixed to the output end of the electric push rod 3 421. This design enables the lifting action of the electric push rod 3 421 to be directly transmitted to the mounting plate 41 to achieve precise height adjustment. The outer side of the mounting plate 41 fits with the inner wall of the mounting frame 11, which not only enhances the stability of the overall structure, but also ensures the stability and alignment accuracy of the mounting plate 41 during the lifting process.

[0057] Through the precise control of the electric push rod 421, the lifting assembly 42 can realize the fast and precise lifting action of the mounting plate 41 to adapt to the working requirements of different heights. This design enables the screw driving mechanism 4 to flexibly adjust the working height to adapt to distribution cabinets of different sizes, thereby improving the adaptability and flexibility of the robot. At the same time, this lifting mechanism also simplifies the operating process, reduces the need for manual adjustment, and improves working efficiency and safety.

[0058] In the distribution cabinet assembly type industrial robot of the present invention, the design of the screw driving assembly 43 is crucial to achieve efficient and accurate screw driving operation. For details, please refer to Figure 1-Figure 10 The screw driving assembly 43 includes a connecting frame 431 which is arranged horizontally and along the width direction of the conveyor belt 22. The connecting frame 431 serves as the main structure of the screw driving assembly 43 and provides a stable platform for the installation and positioning of the screw driving part. Two screw driving parts are symmetrically arranged at the bottom of the connecting frame 431. The four screw driving parts are distributed in a rectangular shape. This symmetrical and uniform layout design enables the screw driving assembly 43 to simultaneously drive screws to multiple screw holes on both sides of the power distribution cabinet, which significantly improves the operating efficiency. The rectangular distribution of the four screw driving parts also matches the typical layout of the screw holes of the power distribution cabinet, ensuring the accuracy and consistency of the screw driving operation.

[0059] The screw driving part includes a device block 432 mounted on a connecting frame 431, a device rod 433 is rotatably mounted at the bottom of the device block 432, a screw driver 434 is mounted at the bottom of the device rod 433, and the screw driver 434 is driven to rotate by the rotation of the device rod 433, so that the screw driving operation can be performed;

[0060] Through this design, the screw driving assembly 43 can not only realize fast and accurate screw driving operations, but also adapt to distribution cabinets of different sizes and shapes. The symmetrical and evenly distributed screw driving part design improves the efficiency and consistency of the operation, and the rotating installation of the device block 432 and the device rod 433 ensures the flexibility and accuracy of the screw driving action. The application of this design reflects the continuous pursuit of high efficiency and high precision in the field of industrial automation, and provides strong technical support for the automated assembly of distribution cabinets.

[0061] In the switchboard assembly type industrial robot of the present invention, the design of the adjustment member 44 is crucial to achieve the precise position adjustment of the screw assembly 43 and the ability to adapt to switchboards of different sizes. For details, please refer to Fig.10The adjusting member 44 comprises two bidirectional screw rods 441 which are arranged horizontally and are arranged along the length direction of the conveyor belt 22. The two ends of the connecting frame 431 are respectively threadedly sleeved on the two bidirectional screw rods 441. The two connecting frames 431 are respectively threadedly sleeved on the positive thread and the negative thread of the bidirectional screw rod 441. One end of the same side of the two bidirectional screw rods 441 is fixedly sleeved with a linkage wheel 442. The two linkage wheels 442 are sleeved with an integrated linkage belt 443. A servo motor 444 whose output end is fixed to the end of one of the bidirectional screw rods 441 is fixed on the mounting plate 41. The servo motor 444 drives the connected bidirectional screw rod 441 to rotate. Through the linkage of the linkage wheel 442 and the linkage belt 443, the two bidirectional screw rods 441 rotate synchronously, and the two connecting frames 431 approach or move away from each other. In this way, the screw driving assembly 43 can be accurately positioned at the screw hole position on the power distribution cabinet to ensure the accuracy and consistency of the screw driving operation.

[0062] The design of the adjustment member 44 not only improves the position adjustment accuracy and adjustment flexibility of the screw driving assembly 43 through the integrated application of a bidirectional screw rod 441 and a servo motor 444, but also enhances the stability and working efficiency of the entire robot system through the cooperation with the linkage wheel 442 and the linkage belt 443.

[0063] For details, please refer to Fig.10 The connecting frame 431 includes two symmetrically arranged connecting blocks 4311, and the two connecting blocks 4311 are respectively threadedly sleeved on two bidirectional screw rods 1 441, and a bidirectional screw rod 2 4312 arranged along the width direction of the conveyor belt 22 is rotatably installed between the two connecting blocks 4311. The two device blocks 432 in the same screw driving assembly 43 are respectively threadedly sleeved on the positive thread and the negative thread of the bidirectional screw rod 2 4312. This design allows the two device blocks 432 to move independently to fine-tune the position of the screw driving, ensuring that the screwdriver 434 can accurately Each screw hole is aligned, and a servo motor 5 4313 whose output end is fixed to one end of the bidirectional screw rod 2 4312 is fixed on one of the connection blocks 4311. The two servo motors 5 4313 run synchronously at the same speed. The servo motor is responsible for driving the bidirectional screw rod 2 4312 to achieve the precise movement of the device block 432 along the bidirectional screw rod 2 4312. In order to ensure the synchronous adjustment of the two screw driving assemblies 43, the two servo motors 5 4313 are designed to run synchronously at the same speed, so as to ensure the coordination and consistency of the screw driving assemblies 43 during the adjustment process;

[0064] Through the bidirectional screw rod 1 441 and the bidirectional screw rod 2 4312, not only can the screw driving assembly 43 be accurately adjusted in two directions, but also the synchronization and accuracy of the adjustment process can be ensured. The use of servo motor 5 4313 further improves the automation and accuracy of the adjustment action, reduces manual intervention, and improves production efficiency and operational safety.

[0065] Furthermore, in the power distribution cabinet assembly type industrial robot of the present invention, the design of the drive assembly 45 is crucial to achieve the synchronous drive and precise control of the screw driving assembly 43, see Figure 4 , Figure 8 and Fig.10 The driving assembly 45 includes a T-shaped slide groove 451 that penetrates the structure on the mounting plate 41 and is arranged along the width direction of the conveyor belt 22. A limited slider 452 is installed inside the T-shaped slide groove 451 for sliding movement. The limited slider 452 can slide freely in the T-shaped slide groove 451 to adapt to different screw driving position requirements. A driving rod 453 is rotated and inserted through the limited slider 452. A spring 454 is connected between one end of the limited slider 452 and one end of the inner wall of the T-shaped slide groove 451. A linkage wheel 3 455 is fixedly sleeved on the driving rod 453 and the four device rods 433. The five linkage wheels 3 455 are located on the same horizontal plane. An integrated linkage belt 3 456 is sleeved between the five linkage wheels 3 455. The vertical projection surface of the linkage belt 3 456 is always a pentagon, and the spring 454 is always in a compressed or stretched state. This unique design helps to improve the transmission of force In order to improve efficiency and stability, a support frame 457 is fixed on the top of the limit slider 452, and a servo motor 6 458 is fixed on the top of the support frame 457, and the output end of the servo motor 6 458 is fixed to the top of the driving rod 453. When the four screw driving parts are adjusted, no matter how the two-way screw rod 1 441 and the two-way screw rod 2 4312 rotate, or how the rectangle enclosed by the four screw driving parts changes, the limit slider 452 is pushed or pulled to move inside the T-shaped slide groove 451 under the elastic force of the spring 454, and the linkage belt 3 456 is always kept in a tight state. At this time, the servo motor 6 458 drives the driving rod 453 to rotate, and the linkage wheel 3 455 connected to the driving rod 453 rotates. Through the tight linkage belt 3 456, the five linkage wheels 3 455 rotate synchronously at the same speed, thereby ensuring that the four screwdrivers 434 rotate synchronously at the same speed, and ensuring the consistency of the tightening degree of the screws;

[0066] The design of the driving component 45 not only improves the synchronous driving accuracy and adjustment flexibility of the screw driving component 43 through the integrated application of the T-shaped slide groove 451, the limiting slider 452, the driving rod 453 and the servo motor six 458, but also enhances the stability and working efficiency of the entire robot system through the cooperation of the connecting wheel three 455 and the connecting belt three 456.

A docking block movably inserted in the docking groove is fixed to the end of the screwdriver 434. A through groove is constructed through the mounting block. A slot is constructed on the docking block. The two ends of the slot correspond to the two through grooves respectively. An integral screw is movably inserted in the two through grooves and the slot. A hexagonal head is fixed to one end of the screw. A nut is threadedly sleeved on the screw. Through the arrangement of the screw and the nut, the docking block can be taken out of the docking groove, thereby replacing different types of screwdrivers 434 to meet different screw driving requirements.

[0069] Embodiment three:

[0070] Embodiment 3 is a further optimization of embodiment 1. The side of the clamping plate 34 facing away from the electric push rod 2 33 is configured with anti-skid patterns. The design of the anti-skid patterns takes into account the sliding phenomenon that may occur during the transportation and screwing of the distribution cabinet on the automated production line. By adding anti-skid patterns on the side of the clamping plate 34 that contacts the distribution cabinet, the friction between the clamping plate 34 and the distribution cabinet can be increased, thereby effectively preventing the distribution cabinet from sliding during the clamping process and ensuring the precise positioning of the distribution cabinet during the screwing process.

[0071] In this solution, the screw-driving process of the distribution cabinet assembly industrial robot is an efficient, accurate and automated operation process. The specific steps are as follows:

[0072] 1. The power distribution cabinet is first placed on the conveyor belt 22 of the conveyor belt assembly 2. The conveyor belt 22 is supported by a plurality of rotating rollers 21 and driven by a servo motor 24 to ensure that the power distribution cabinet moves smoothly along the production line;

[0073] Second, when the power distribution cabinet reaches the predetermined position, the clamping and fixing mechanism 3 starts to work, and the two clamping members move along the mounting frame 11 to the two sides of the power distribution cabinet. The electric push rod 1 32 and the electric push rod 2 33 work together to make the clamping plate 34 clamp the power distribution cabinet to ensure the stability of the power distribution cabinet during the screwing process;

[0074] 3. The screw driving mechanism 4 is adjusted to a position suitable for the height of the power distribution cabinet through the lifting assembly 42, and the screw driving assembly 43 is fine-tuned through the adjusting member 44 and the driving assembly 45 to ensure that the screwdrivers 434 of the four screw driving parts are accurately aligned with the screw holes on the power distribution cabinet;

[0075] Fourth, the servo motor 6 458 drives the driving rod 453, and through the linkage wheel 3 455 and the linkage belt 3 456, synchronously drives the four device rods 433, so that the four screwdrivers 434 start to rotate at the same time to perform the screw driving operation. This synchronous operation ensures that all screws are tightened with the same force and speed, thereby improving the consistency and reliability of screw driving;

[0076] 5. After the screws on one side are driven, the electric push rod 1 32 lifts the clamping plate 34, so that the power distribution cabinet is lifted to a certain height, and the servo motor 331 drives the clamping plate 34 to rotate, so that the power distribution cabinet is turned over, with the side without screws facing upwards, and then the electric push rod 1 32 controls the clamping plate 34 to descend, and the power distribution cabinet is stably placed back on the conveyor belt 22, ready for the screwing operation on the other side;

[0077] 6. Repeat steps 4 and 5 to screw the screw holes on the other side of the power distribution cabinet;

[0078] 7. After all the screws are screwed into the four side screw holes of the power distribution cabinet, the electric push rod 23 releases the clamping, and the power distribution cabinet is released and continues to move forward along the conveyor belt 22 to enter the next production link.

[0079] It should be particularly noted that the specific models and specifications of servo motor 24, electric push rod 1 32, electric push rod 2 33, servo motor 3 331, servo motor 2 354, electric push rod 3 421, servo motor 5 4313, servo motor 444, and servo motor 6 458 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The principles of these components are clear to those skilled in the art and do not need to be described in detail here.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
