Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner manufacturing technology, specifically to a vacuum cleaner assembly line. Background Technology

[0002] A vacuum cleaner is a device that uses an electric motor to drive blades to rotate at high speed, thereby creating negative air pressure within a sealed casing to suck up dust. Vacuum cleaners are widely used in industrial and household applications, with household vacuum cleaners being the most produced. Therefore, factories typically need to establish assembly lines to mass-produce household vacuum cleaners.

[0003] The patent application with publication number CN102139449A, entitled "Assembly Production Line for Upright Vacuum Cleaners," provides a production line for vacuum cleaners. The patent's technical solution mainly divides the different stages of the vacuum cleaner assembly process into different work areas and performs them sequentially. However, it does not describe how to quickly and stably transfer parts within each work area. In addition, each assembly area in this patent's technical solution requires a dedicated workbench, which greatly increases production costs.

[0004] In existing factories, vacuum cleaner assembly typically involves placing the main components on a conveyor belt. Operators then remove these components from the conveyor belt and place them on standardized workbenches for assembly. After assembly, the assembled components are placed back on the conveyor belt for the next process. However, because the conveyor belt is designed for easy access to parts, its transport speed is slow. When the assembly of a main component requires multiple parts, it takes a long time to collect them all. As a result, operators waste a significant amount of time waiting for parts to arrive. Furthermore, placing all components on the same conveyor belt makes it inconvenient to select parts. Moreover, the existing conveyor belt and standardized workbench configuration can only expand the number of workstations to a fixed number, making it difficult to flexibly modify the production line to improve production efficiency.

[0005] Therefore, we need a vacuum cleaner assembly line to solve the problems of existing production lines being unable to smoothly transport parts and obtain components, resulting in low efficiency and inconvenience in flexibly modifying the production line. This can effectively improve production efficiency. Summary of the Invention

They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 9This invention provides a vacuum cleaner assembly line, including a testing and debugging area 19, a final assembly area 20, a motor assembly area 21, a handle assembly area 22, and a circuit assembly area 23. At least one unit workbench 1 is respectively provided inside the testing and debugging area 19, the final assembly area 20, the motor assembly area 21, the handle assembly area 22, and the circuit assembly area 23. The unit workbench 1s located in the circuit assembly area 23, the final assembly area 20, and the testing and debugging area 19 are connected in series. The unit workbench 1 located in the motor assembly area 21 is connected in series to the side of the unit workbench 1 located in the circuit assembly area 23. The unit workbench 1 located in the handle assembly area 22 is connected in series to the side of the unit workbench 1 located in the circuit assembly area 23. The side of the unit workbench 1 in the assembly area 23 or the general assembly area 20; the debugging and testing area 19 is used to debug and test the performance of the assembled vacuum cleaner; the general assembly area 20 is used to install the handle and motor inside the vacuum cleaner housing and assemble the upper and lower shells of the vacuum cleaner together to form a complete vacuum cleaner; the motor assembly area 21 is used to assemble the motor required for the vacuum cleaner and the corresponding auxiliary parts that can be installed on the motor; the handle assembly area 22 is used to assemble the handle assembly of the vacuum cleaner into a handle; the circuit assembly area 23 is used to install the circuit required for the vacuum cleaner, including circuit boards, indicator lights, power cords and other electrical components, inside the bottom and upper shells of the vacuum cleaner. Please see Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9The unit workbench 1 includes a work surface 13 for assembling vacuum cleaner parts 14, and a conveyor 16 is provided on the side of the work surface 13. The conveyor 16 is provided with a conveying device 5 for transporting vacuum cleaner parts 14. The unit workbench 1 is provided with an equipment platform 11 for installing assembly tools and equipment. The unit workbench 1 is provided with a clamping device 3 for gripping the vacuum cleaner parts 14 located on the conveyor 5 onto the work surface 13. The work surface 13 is provided with a second position adjustment device 6 for adjusting the height and direction of the clamping device 3. The work surface 13 is provided with a first position adjustment device 7 for adjusting the left and right positions of the second position adjustment device 6. The work surface 13 is provided with a controller 8 for controlling the working status of the conveyor 5, the first position adjustment device 7, the second position adjustment device 6 and the clamping device 3. Multiple adjacent unit workbenches 1 can be connected end-to-end, meaning the end of the conveyor 16 of the front unit workbench 1 is connected to the front of the conveyor 16 of the rear unit workbench 1. This allows vacuum cleaner parts 14 to be transported sequentially from the loading area through the connected conveyor 16s between the unit workbench 1s. The conveyor 16 of the unit workbench 1 at the very front of the series connection also handles the loading process, typically done manually or by a robotic arm, placing the parts onto the conveyor 5 of that unit workbench 1. The last unit workbench 1 in the series within its corresponding work area also handles the transfer of vacuum cleaner parts 14 to the next work area. The task involves connecting the unit workbenches 1 in the circuit assembly area 23, the main assembly area 20, and the debugging and testing area 19. This allows the vacuum cleaner components 14 located in these areas to be directly fed from the unit workbench 1 at the front of the circuit assembly area 23, and then transported to the unit workbench 1 at the rear of the debugging and testing area 19. During this process, the vacuum cleaner components 14 are assembled into a vacuum cleaner. Qualified vacuum cleaner products are then manually or robotically removed from the unit workbench 1 at the rear of the debugging and testing area and sent to the external packaging area for packaging. Products that fail debugging and testing are removed manually or robotically and sent to the waste area for processing.Vacuum cleaner components 14 in the motor assembly area 21 are fed by the unit workbench 1 at the frontmost end of the series within the motor assembly area 21. Then, the conveying device 5 on the unit workbench 1 at the rearmost end of the series within the motor assembly area 21 feeds the assembled motor components from the side of the unit workbench 1 in the circuit assembly area 23 onto the conveying device 5 of the unit workbench 1 in the circuit assembly area 23. Similarly, vacuum cleaner components 14 in the handle assembly area 22 are fed by the unit workbench 1 at the frontmost end of the series within the handle assembly area 22. Then, the conveying device 5 on the unit workbench 1 at the rearmost end of the series within the handle assembly area 22 feeds the assembled handle from the side of the unit workbench 1 in the circuit assembly area 23 or from the side of the unit workbench 1 at the frontmost end of the series within the main assembly area 20 onto the conveying device 5 of the corresponding unit workbench 1.After the vacuum cleaner component 14 enters the conveying device 5 of a certain unit workbench 1, the clamping device 3 will grab the corresponding vacuum cleaner component 14 onto the workbench surface 13 according to the assembly work required on the unit workbench 1. Specifically, the operator first needs to input the assembly steps required by the unit workbench 1 and the vacuum cleaner component 14 to be grabbed to complete the assembly steps into the controller 8 of the unit workbench 1. Then, the operator located in the unit workbench 1 can control the operation of the controller 8. When the operator issues the material picking command, the controller 8 will adjust the device 7 to the first position according to the preset control program. The second position adjustment device 6 and the clamping device 3 issue corresponding work commands, enabling the clamping device 3 to grab the corresponding number of various vacuum cleaner parts 14 required for this assembly process from the conveying device 5 and place them in the parts placement area on the worktable 13. The operator can then move the vacuum cleaner parts 14 from the parts placement area to the assembly area at the rear of the worktable 13. The operator then issues another work command to the controller 8 to use the clamping device 3 to grab the vacuum cleaner parts 14 required for the next assembly and place them in the parts placement area on the worktable 13. After completing this assembly, the operator can... The assembled components are placed directly onto the conveyor 5 to proceed to the next process. The operator then moves the vacuum cleaner component 14 from the component placement area to the assembly area at the rear of the workbench 13 and issues a work command to the controller 8. The clamping device 3 then grabs the next required vacuum cleaner component 14 and places it in the component placement area. This process is repeated to complete the assembly work required for this unit's workbench 1. The advantage of this method is that it can handle situations where multiple vacuum cleaner components 14 need to be removed from the conveyor 5 during sequential assembly, and these components cannot be gathered quickly enough. The clamping device 3 can be used to grab the workpiece during the assembly process, thus avoiding the need for operators to wait for a long time after completing an assembly before the conveyor device 5 delivers the corresponding parts. On the other hand, since it is not necessary for operators to directly grab the vacuum cleaner parts 14 from the conveyor device 5, but only to place the vacuum cleaner parts 14 or finished vacuum cleaners that have completed the corresponding assembly process onto the conveyor device 5, the conveyor device 5 can also transport the vacuum cleaner parts 14 at a faster speed without having to wait for the operators to complete the picking of the corresponding vacuum cleaner parts 14. This can effectively improve work efficiency.In addition, to ensure that the unit workbench 1 can assist operators in completing the corresponding assembly work, the unit workbench 1 can also use the equipment platform 11 to house corresponding equipment or tools. For example, a soldering gun can be placed in the equipment platform 11 of the unit workbench 1 located in the circuit assembly area 23, an electric screwdriver can be placed in the equipment platform 11 of the unit workbench 1 located in the motor assembly area 21, an electric screwdriver, calipers, etc. can be placed in the equipment platform 11 of the unit workbench 1 located in the general assembly area 20 and the handle assembly area 22, and a multimeter, etc. can be placed in the debugging and testing area 19, so that the corresponding unit workbench 1 has the hardware support to complete the corresponding assembly operation.

[0022] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The conveying device 5 includes a conveyor belt 501, and each conveyor table 16 is provided with at least two drive devices 4 for driving the conveyor belt 501. The drive device 4 includes a support shaft 401 rotatably mounted with the conveyor table 16 and used to support the conveyor belt 501, and a driven wheel 404 is fixedly mounted on the support shaft 401.

A mounting frame 407 is fixedly mounted on the conveyor table 16, and a main drive motor 402 is fixedly mounted on the mounting frame 407. The output end of the main drive motor 402 drives a drive wheel 406. An intermediate gear 405 is rotatably mounted on the mounting frame 407, and the intermediate gear 405 is respectively connected to the drive wheel. 406 and driven wheel 404 are meshed and connected. The main drive motor 402 is electrically connected to the controller 8. When the conveying device 5 needs to convey the vacuum cleaner parts 14, the controller 8 drives the main drive motor 402 to work. At this time, the main drive motor 402 will drive the intermediate gear 405 to rotate through the drive wheel 406. The intermediate gear 405 will drive the driven wheel 404 to rotate. Then the driven wheel 404 will drive the support shaft 401 to rotate. At the same time, the driven wheel 404 can also drive the conveyor belt 501 to drive through the rack 503 meshing with the driven wheel 404. The conveyor belt 501 is a conveyor belt and can be supported by the support shaft 401 to maintain the stability of the upper surface.

[0023] Please see Figure 2 , Figure 3 and Figure 4The front end of the conveyor 16 is fixedly equipped with a front docking frame 18 for connecting the rear end of the conveyor 16 in the adjacent unit workbench 1. The side of the conveyor 16 is provided with a side docking frame 17 for connecting the rear end of the conveyor 16 in the adjacent unit workbench 1 at the position corresponding to the clamping device 3. Both the front docking frame 18 and the side docking frame 17 are provided with a first camera 15 that is electrically connected to the controller 8 and is used to detect the position and model of the vacuum cleaner parts 14. The front docking frame 18 and the side docking frame 17 are used to fix the end of the conveyor 16 of the adjacent unit workbench 1, so that the two adjacent conveyor 16 can be correctly docked. At the same time, the first camera 15 provided on the front docking frame 18 and the side docking frame 17 can also complete the image acquisition of the vacuum cleaner parts 14 passing through the corresponding area. Then, the image recognition system integrated in the controller 8 determines the specific type of vacuum cleaner parts 14 in the acquired image, which facilitates the controller 8 to control the clamping device 3 to perform precise selective clamping.

[0026] Please see Figure 2 , Figure 7 , Figure 8 and Figure 9The clamping device 3 includes a guide rod 308 fixedly installed with the docking seat 608, and a pair of sliders 307 symmetrically slidably installed at the front and rear ends of the guide rod 308. A clamping arm 306 for clamping the vacuum cleaner component 14 is fixedly installed at the bottom of the slider 307. A push arm 303 is rotatably installed in the middle of the guide rod 308 via a connecting shaft, and the end of the push arm 303 is hinged to the slider 307 via a connecting arm 305. A clamping drive motor 301 is fixedly installed in the middle of the guide rod 308, and a worm gear 302 is driven at the output end of the clamping drive motor 301. A worm gear 304 is fixedly installed at the end of the shaft, and the worm 302 and the worm gear 304 are meshed together. A second camera 10 for detecting the position and model of the vacuum cleaner component 14 is set at the middle of the guide rod 308. The second camera 10 and the clamping drive motor 301 are electrically connected to the controller 8. A detachable parts placement table 12 for placing parts needed in the assembly process is fixedly installed at the rear end of the worktable 13 by bolts. A display 9, which is electrically connected to the controller 8 and is used to display the working status of the controller 8, is fixedly installed on the worktable 13.

Specifically, when the controller 8 detects through the first camera 15 that a vacuum cleaner component 14 needs to be grasped is moving and guided to the corresponding grasping position, the controller 8 will use the cooperation of the first lead screw motor 701 and the second lead screw motor 705 to transport the clamping device 3 to the corresponding grasping position. Then, according to the placement angle of the corresponding vacuum cleaner component 14 collected by the first camera 15, the clamping arm 306 is adjusted to the appropriate clamping direction by the direction adjustment motor 603. Then, the clamping arm 306 is pushed down to the appropriate clamping height by the height adjustment push rod 601. The clamping drive motor 301 drives the clamping arm 306 to clamp the corresponding vacuum cleaner component 14. After clamping, the height adjustment push rod 601 is used to raise the height of the clamping device 3 and the vacuum cleaner component 14. Then, with the cooperation of the first lead screw motor 701 and the second lead screw motor 705, the vacuum cleaner component 14 is transported to the top of the workbench 13. Subsequently, the height adjustment push rod 601 and the clamping drive motor 301 work together to place the vacuum cleaner component 14 into the component placement area on the workbench 13. In the above process, when the clamping arm 306 needs to clamp the vacuum cleaner component 14, the clamping drive motor 301 first... When the clamping drive motor 301 rotates clockwise, it drives the worm gear 302 to rotate, which in turn drives the worm wheel 304 to rotate. The worm wheel 304 then drives the push arm 303 to rotate. The push arm 303, connecting arm 305, slider 307, and guide rod 308 form a crank-slider mechanism, which allows the push arm 303 to drive the slider 307 to move along the guide rod 308. When the clamping drive motor 301 rotates clockwise, the slider 307 moves towards the center of the guide rod 308, at which point the clamping arm 306 clamps the vacuum cleaner component 14. When the clamping drive motor 301 rotates counterclockwise... When the slider 307 moves away from the center of the guide rod 308, the clamping arm 306 will release the vacuum cleaner component 14. During the above process, the rotation angle of the push arm 303 can be controlled by the clamping drive motor 301 to control the distance the slider 307 slides along the guide rod 308. In this way, the clamping force of the clamping arm 306 on the corresponding vacuum cleaner component 14 can be adjusted according to the size of different vacuum cleaner components 14. The size of various vacuum cleaner components 14 and how to use the clamping drive motor 301 to rotate at different angles to correspond to them are pre-entered into the corresponding database by the relevant operators during programming.On the other hand, the worm 302 and the worm wheel 304 can also form a worm gear transmission mechanism and provide a self-locking function, so that after the clamping arm 306 clamps the vacuum cleaner part 14, the operation of the clamping drive motor 301 can be stopped. In this way, the worm gear transmission mechanism can still provide clamping force on the vacuum cleaner part 14 to prevent the vacuum cleaner part 14 from falling off, while also saving unnecessary energy consumption.In addition, the direction adjustment motor 603 and the distance adjustment push rod 604 also provide the following functions: First, they prevent the vacuum cleaner component 14 from tilting during the clamping process. Since the conveyor device 5 transports the vacuum cleaner component 14 at a specified speed, if the clamping arm 306 only moves vertically up and down under the push of the height adjustment push rod 601, then the clamping arm 306 and the vacuum cleaner component 14 are not relatively stationary in the horizontal direction during the clamping process. At this time, the side of the vacuum cleaner component 14 is subjected to the clamping force from the clamping arm 306, while the bottom of the vacuum cleaner component 14 is subjected to the friction force from the conveyor belt 501, thus causing the vacuum cleaner component 14 to be subjected to uneven force. In cases where the vacuum cleaner component 14 flips over, causing damage, the direction adjustment motor 603 and distance adjustment push rod 604 are used to adjust the docking seat 608 towards the direction of movement of the conveyor device 5. Then, the distance adjustment push rod 604 is used to adjust the clamping device 3 to move synchronously with the conveyor belt 501. This allows the clamping arm 306 to clamp the vacuum cleaner component 14 while remaining relatively stationary with respect to the conveyor belt 501. Secondly, it assists in correctly transporting the vacuum cleaner component 14 from the conveyor device 5 docked with the side docking frame 17 to the conveyor device 5 of the docking unit workbench 1. For example, a motor or other means are used to transport the vacuum cleaner component 14 correctly from the conveyor device 5 docked with the side docking frame 17 to the conveyor device 5 of the docking unit workbench 1. Small parts may get stuck at the end of the conveyor 5, which connects to the side docking frame 17, during the conveying process. In this case, the second camera 10 needs to inspect the area during the non-gripping operation of the clamping device 3. When a vacuum cleaner part 14 is found to be stuck, the clamping device 3 will grab the corresponding vacuum cleaner part 14 and put it in the correct position. Thirdly, the first camera 15 and the second camera 10 can be used to check the spacing and placement of the vacuum cleaner parts 14 on the conveyor 5. If the placement or angle of the vacuum cleaner parts 14 is incorrect, or if the spacing between adjacent vacuum cleaner parts 14 is incorrect, the camera will detect the problem. When the spacing is not ideal, the clamping device 3 can be used to clamp the corresponding vacuum cleaner parts 14, and then the position and angle can be adjusted to allow for a suitable spacing between the vacuum cleaner parts 14 before they are placed back onto the conveying device 5. This effectively ensures that the vacuum cleaner parts 14 are transported on the conveying device 5 in the correct manner. Fourthly, it facilitates the placement of the vacuum cleaner parts 14 gripped by the clamping device 3 into the appropriate position on the workbench 13. By adjusting the rotation direction of the docking seat 608 and the distance that the docking seat 608 is pushed out by the distance adjustment push rod 604, the corresponding type of vacuum cleaner parts 14 can be effectively placed into the corresponding preset position, making it convenient for operators to pick them up.

[0027] As required by the assembly work, when multiple unit workbenches 1 need to be assembled simultaneously within the working areas of debugging and testing area 19, final assembly area 20, motor assembly area 21, handle assembly area 22, and circuit assembly area 23 to complete the current task, the unit workbenches 1 located within the corresponding working areas are assembled in series, and then... Figure 1 The assembly process described above can be flexibly adjusted according to the assembly requirements of the specific models of vacuum cleaners being produced, thereby dividing the production line into different assembly areas to meet the production needs of different models of vacuum cleaners.

[0028] The vacuum cleaner assembly line designed in this embodiment can be freely assembled into various production line forms using unit workbenches 1 to meet the production needs of different models of vacuum cleaners. It also facilitates the division of different assembly functional areas and the expansion of positions, providing better production flexibility. Furthermore, it can automatically grasp vacuum cleaner parts 14 by using the cooperation of clamping device 3 and conveying device 5, thereby saving operators' waiting time. It solves the problems of existing production lines that cannot smoothly transport parts and have low efficiency in acquiring parts, and are not convenient for flexible modification of the production line, thus effectively improving production efficiency.

[0029] Example 2: Please refer to Figures 2 to 6Based on Embodiment 1, the conveyor belt 501 is provided with mating slides 502 on both the left and right sides of the corresponding rack 503, and the mounting bracket 407 is fixedly mounted with guide rails 403 that slide along the mating slides 502 and are used to prevent the conveyor belt 501 from disengaging from the upper and lower ends of the support shaft 401. The front and rear ends of the conveyor table 16 are respectively provided with a pair of end support shafts 24 on the left and right sides, and the end support shafts 24 are used to support the conveyor belt 501. Since the movement of the conveyor belt 501 depends on the meshing of the driven wheel 404 and the rack 503, and the friction between the conveyor belt 501 and the support shaft 401, if the conveyor belt 501 cannot adhere to the surface of the support shaft 401, the driven wheel 404 will also not be able to mesh correctly with the rack 503. Therefore, the conveyor belt 501 will not be able to move correctly. By adding guide rails 403, the sliding action between the guide rails 403 and the mating slides 502 can be used to firmly press the conveyor belt 501 onto the support shaft. The surface of shaft 401 ensures that rack 503 can properly mesh with driven wheel 404, thus ensuring that main drive motor 402 can correctly drive conveyor belt 501 to move. This ensures that the entire production line can stably transport various vacuum cleaner parts 14 at a preset speed, ensuring production stability. In addition, the end support shaft 24 supports the end of conveyor belt 501, which can effectively allow two adjacent conveyor belts 501 to dock with a smaller gap and complete the docking process with a smaller height change in the docking transition area. Compared with the traditional method of docking with a single roller, this can effectively avoid the problem of vacuum cleaner parts 14 getting stuck at this point, thus ensuring the stable operation of the production line. This further solves the problems of existing production lines being unable to smoothly transport parts and obtain parts with low efficiency, and it is not convenient to flexibly modify the production line. It can effectively improve production efficiency.

[0030] Example 3: Please refer to Figures 7 to 10Based on Embodiment 2, the end of the clamping arm 306 is provided with an adaptive clamp 2 for clamping the vacuum cleaner component 14. The adaptive clamp 2 includes a connecting plate 201 fixedly installed at the end of the clamping arm 306, and a pair of arc-shaped frames 202 are symmetrically hinged at the left and right ends of the connecting plate 201. Each arc-shaped frame 202 is symmetrically hinged with a pair of arc-shaped clamping blocks 204 for clamping the vacuum cleaner component 14 via connecting protrusions 203. The adaptive clamp 2 designed in this invention can better adapt to different types of vacuum cleaner components 14 with different surface shapes. Taking the bottom shell of the vacuum cleaner as an example, the cross-section of the bottom shell of the vacuum cleaner is generally cylindrical or rectangular. The vacuum cleaner's bottom shell is typically curved, either shaped like a spherical or elliptical shape. This means that the two sides clamped by the clamping arm 306 generally have a certain degree of curvature. If a flat surface is used for clamping, it can easily lead to point contact between the clamping arm 306 and the vacuum cleaner's bottom shell. This results in excessive force on the clamped area of ​​the vacuum cleaner's bottom shell, causing deformation and wear. Furthermore, it can easily cause rotation and wobbling during clamping. Therefore, it is essential to ensure that the clamping arm 306 can clamp the vacuum cleaner's bottom shell in a surface contact manner. The self-adaptive clamp 2 on the clamping arm 306 solves this problem. When the vacuum cleaner component 14 has an arc-shaped clamping block 204 that contacts other areas first, the arc-shaped clamping block that fits into that area... 204 will rotate under the push of force, and the force will also be transmitted to the arc-shaped frame 202, causing the arc-shaped frame 202 to rotate as well. This will push out the arc-shaped clamp 204 at the other end of the arc-shaped frame 202 and make contact with the corresponding area of ​​the vacuum cleaner component 14. In this way, the arc-shaped frame 202 will only stop rotating when both arc-shaped clamps 204 on both sides of the arc-shaped frame 202 are in contact with the vacuum cleaner component 14, thereby achieving clamping with at least two areas in contact. Moreover, the outer surface of the arc-shaped clamp 204 can be made of rubber, so that it can better contact with the vacuum cleaner component 14, thereby achieving surface contact. On the other hand, when the vacuum cleaner component... When the size of component 14 is larger, two arc-shaped frames 202 can be used to press against the side of the vacuum cleaner component 14. At this time, since the arc-shaped frames 202 will rotate after being subjected to force, it can be ensured that at least one arc-shaped clamping block 204 on each arc-shaped frame 202 will clamp with the outer wall of the vacuum cleaner component 14, so that the two areas can still form surface contact. This can ensure the clamping effect and achieve effective clamping of various vacuum cleaner components 14 required for assembling the vacuum cleaner. This further solves the problem that the existing production line cannot smoothly transport components and obtain parts at the same time, resulting in low efficiency and inconvenience in flexibly modifying the production line. It can effectively improve production efficiency.

At the same time, connect the unit workbench 1 within each functional area to each other, and then connect the unit workbench 1 belonging to different functional areas according to... Figure 1 The connection is made in a certain way, and the control program required for assembly is input into the controller 8 in each unit workbench 1, so as to assemble and form a production line. Step 2: The components that make up the vacuum cleaner, such as the upper shell, bottom shell, and circuit board, are loaded onto the unit workbench 1 at the front of the circuit assembly area 23, so that these components can be assembled by the operators on the corresponding unit workbench 1 when passing through the circuit assembly area 23. The components such as the motor and fan blades are loaded onto the unit workbench 1 at the front of the motor assembly area 21, so that these components can be assembled onto the motor after passing through the motor assembly area 21. The components that make up the handle, such as the handle and telescopic rod, are loaded onto the unit workbench 1 at the front of the handle assembly area 22, so that these components can form a complete handle after being assembled in the handle assembly area 22. Step 3: Subsequently, the bottom shell, top shell, motor, and handle, among other components, will be gathered in the final assembly area 20, where operators will assemble them into a complete vacuum cleaner. The assembled vacuum cleaner will then be sent to the testing and debugging area 19 for testing and quality inspection by operators. Products that pass the quality test will be sent to the subsequent packaging stage, while products that fail the quality test will be separated and processed.
