Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaner production, in particular to a vacuum cleaner assembly line. Background Art

[0002] A vacuum cleaner is a device that uses a motor to drive the blades to rotate at high speed, thereby generating negative air pressure in a sealed shell to absorb dust. Vacuum cleaners are widely used in industrial and household fields, among which household vacuum cleaners are produced in the largest number, so factories generally need to establish assembly lines to mass-produce household vacuum cleaners.

[0003] The patent with application publication number CN102139449A and patent name "Assembly Line for Upright Vacuum Cleaners" provides a vacuum cleaner production line. The patent's technical solution mainly divides the different stages of the vacuum cleaner assembly process into different working areas and performs them in sequence. However, it does not introduce how to quickly and stably transfer parts in each working area. At the same time, a dedicated workbench needs to be set up in each assembly area in the patent's technical solution, which greatly increases the production cost.

[0004] In existing factories, the assembly of vacuum cleaners generally involves placing the main components of the vacuum cleaner on a conveyor belt, and then the operators take these components off the conveyor belt and place them on a universal workbench for assembly and processing. After the assembly and processing are completed, the assembled components are placed on the conveyor belt for processing in the next process. However, in this process, the conveyor belt is used to facilitate the convenience of personnel in various places to take parts, so the transportation speed is slow. When the assembly process of a main component requires multiple components, it takes a long time to collect them all. Therefore, a lot of the operator's time is wasted in the process of waiting for the components to be transmitted. At the same time, placing all the components on the same conveyor belt is not convenient for the selection of components. Moreover, the number of workstations that can be expanded by the existing conveyor belt with a universal workbench is fixed, and it is difficult to flexibly modify the production line to improve production efficiency.

[0005] Therefore, we need a vacuum cleaner assembly line to solve the problem that the existing production line cannot transport parts smoothly and the efficiency of obtaining parts is low, and it is not convenient to flexibly modify the production line, which can effectively improve production efficiency.

A plurality of adjacent unit workbenches 1 can be connected in series end to end, that is, the end of the conveyor table 16 of the unit workbench 1 at the front end is connected to the front end of the conveyor table 16 of the unit workbench 1 at the rear end, so that the vacuum cleaner parts 14 can be transported from each unit workbench 1 through the loading area in sequence through each of the conveyor tables 16 connected in series to the end, and the conveyor table 16 of the unit workbench 1 at the front end of the series position also needs to undertake the loading work, generally by manually or by a robot to place the corresponding parts on the conveying device 5 of the unit workbench 1 to complete the loading process, and the last unit workbench 1 in series located in the corresponding working area also needs to undertake the delivery of the vacuum cleaner parts 14 to the next working area. Task, wherein since the unit workbenches 1 in the circuit assembly area 23, the general assembly area 20 and the debugging and testing area 19 can be directly connected in series, the vacuum cleaner parts 14 located in these areas can be directly loaded by the unit workbench 1 located at the front end of the circuit assembly area 23, and then transported to the unit workbench 1 located at the rear end of the debugging and testing area 19 and assembled into the vacuum cleaner in the above process, and the qualified vacuum cleaner products on the unit workbench 1 at the rear end of the debugging and testing area 19 are taken down manually or by a robot and sent to the external packaging area for packaging, while the unqualified products after debugging and testing are taken down manually or by a robot and sent to the waste area for processing.The vacuum cleaner parts 14 in the motor assembly area 21 are loaded by the unit workbench 1 located at the front end of the series connection in the motor assembly area 21, and then the conveying device 5 on the unit workbench 1 located at the rear end of the series connection in the motor assembly area 21 delivers the assembled motor parts from the side of the unit workbench 1 located in the circuit assembly area 23 to the conveying device 5 of the unit workbench 1 located in the circuit assembly area 23. Similarly, the vacuum cleaner parts 14 in the handle assembly area 22 are loaded by the unit workbench 1 located at the front end of the series connection in the handle assembly area 22, and then the conveying device 5 on the unit workbench 1 located at the rear end of the series connection in the handle assembly area 22 delivers the assembled handle from the side of the unit workbench 1 located in the circuit assembly area 23 or the side of the front end of the unit workbench 1 located in the general assembly area 20 to the conveying device 5 of the corresponding unit workbench 1.After the vacuum cleaner parts 14 enter the conveying device 5 of a certain unit workbench 1, the clamping device 3 will be used to grab the corresponding vacuum cleaner parts 14 onto the workbench surface 13 according to the assembly work required on the unit workbench 1. The specific method is as follows: first, the operator needs to input the assembly steps required to be implemented by the unit workbench 1 and the vacuum cleaner parts 14 required to be grabbed to complete the assembly steps into the controller 8 of the unit workbench 1, and then the operator located in the unit workbench 1 can control the working process of the controller 8. When the operator issues a material collection instruction, the controller 8 will adjust the first position of the first position according to the preset control program. , the second position adjustment device 6 and the clamping device 3 issue corresponding work instructions, so that the clamping device 3 can grab a 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 workbench 13. Then the operator can take the vacuum cleaner parts 14 located in the parts placement area to the assembly area at the rear end of the workbench 13. Then the operator issues a work instruction to the controller 8 again to use the clamping device 3 to grab the vacuum cleaner parts 14 required for the next assembly to the parts placement area on the workbench 13. When the operator completes this assembly, the operator can The corresponding parts that have been assembled are directly placed on the conveying device 5 so that they can enter the next process. Then the operator can take the vacuum cleaner parts 14 located in the parts placement area to the assembly area located at the rear end of the workbench 13 and issue a work instruction to the controller 8 again, so as to use the clamping device 3 to grab the vacuum cleaner parts 14 required for the next assembly and put them in the parts placement area. The above process can be repeated to complete the assembly work that needs to be completed in the unit workbench 1. The advantage of using this method is that when multiple vacuum cleaner parts 14 need to be taken out of the conveying device 5 during the assembly process, and these vacuum cleaner parts 14 cannot be assembled in a short time. At this time, the operator's time in the assembly process can be used to complete the operation of grabbing the workpiece through the clamping device 3, thereby avoiding the operator having to wait for a long time for the conveying device 5 to transport the corresponding parts after completing an assembly. On the other hand, since there is no need for manual labor to directly grab the vacuum cleaner parts 14 from the conveying device 5, but only needs to manually place the vacuum cleaner parts 14 that have completed the corresponding assembly procedures or the vacuum cleaner finished products on the conveying device 5, the conveying device 5 can also transport the vacuum cleaner parts 14 at a faster speed without having to wait for the operator to complete the picking of the corresponding vacuum cleaner parts 14, which can effectively improve work efficiency.In addition, in order to ensure that the unit workbench 1 can assist the operator to complete the corresponding assembly work, the corresponding unit workbench 1 can also use the equipment platform 11 to prevent corresponding equipment or tools. For example, a soldering gun can be placed on the equipment platform 11 of the unit workbench 1 located in the circuit assembly area 23, an electric screwdriver can be placed on the equipment platform 11 of the unit workbench 1 located in the motor assembly area 21, an electric screwdriver, calipers, etc. can be placed on 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 work.

In the above process, the rotation angle of the pushing arm 303 can be controlled by the clamping drive motor 301 to control the sliding distance of the slider 307 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 the different vacuum cleaner components 14. The sizes of various vacuum cleaner components 14 and how to use the clamping drive motor 301 to rotate 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 the clamping drive motor 301 can be stopped after the clamping arm 306 clamps the vacuum cleaner component 14. In this way, the worm gear transmission mechanism can still be used to provide clamping force for the vacuum cleaner component 14 to prevent the vacuum cleaner component 14 from falling, while also saving unnecessary energy loss.In addition, the direction adjustment motor 603 and the distance adjustment push rod 604 also provide the following functions: First, they provide the function of preventing the vacuum cleaner component 14 from tilting during the clamping process. Since the conveying device 5 transports the vacuum cleaner component 14 at a specified speed, if the clamping arm 306 only moves straight up and down under the push of the height adjustment push rod 601, then during the clamping process, the clamping arm 306 and the vacuum cleaner component 14 are not relatively static in the horizontal direction. At this time, the side of the vacuum cleaner component 14 is subjected to the clamping force from the clamping arm 306, and the bottom of the vacuum cleaner component 14 is subjected to the friction force from the conveyor belt 501, so that the vacuum cleaner component 14 will be subjected to uneven force. In this case, the vacuum cleaner parts 14 may be flipped over and damaged. By setting a direction adjustment motor 603 and a distance adjustment push rod 604, the direction adjustment motor 603 can adjust the docking seat 608 to the direction of movement toward the conveying device 5, and then the distance adjustment push rod 604 can be used to adjust the clamping device 3 to a state of synchronous movement with the conveyor belt 501. In this way, the clamping arm 306 can clamp the vacuum cleaner parts 14 while being relatively still with the conveyor belt 501. Secondly, the auxiliary vacuum cleaner parts 14 are correctly transported from the conveying device 5 docked with the side docking frame 17 to the conveying device 5 of the docked unit workbench 1, such as a motor or other During the process of being transported by the conveying device 5, small parts may be stuck at the end of the conveying device 5 docked with the side docking frame 17 due to some problems. At this time, it is necessary to use the second camera 10 to check the area during the non-grasping working time of the clamping device 3, so that when it is detected that a vacuum cleaner part 14 is stuck, the corresponding vacuum cleaner part 14 can be grabbed to the correct position through the clamping device 3; thirdly, the first camera 15 and the second camera 10 can be used to check the spacing and placement position of the vacuum cleaner parts 14 on the conveying device 5. When the placement position or placement angle of the vacuum cleaner parts 14 is incorrect and the swing angle between adjacent vacuum cleaner parts 14 is incorrect, When the spacing is not important, the clamping device 3 can be used to clamp the corresponding vacuum cleaner parts 14, and then the position and angle can be adjusted and then put back on the conveying device 5 with a suitable spacing between the vacuum cleaner parts 14. This can effectively ensure that the vacuum cleaner parts 14 are transported on the conveying device 5 in the correct form; fourthly, it is convenient to place the vacuum cleaner parts 14 grasped by the clamping device 3 at the appropriate position of the work surface 13. By adjusting the rotation direction of the docking seat 608 and the distance by which 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 at the corresponding preset position, thereby facilitating the operator to take them.

[0027] According to the needs of the assembly work, when multiple unit workbenches 1 are required to perform assembly work simultaneously in the debugging and testing area 19, the general assembly area 20, the motor assembly area 21, the handle assembly area 22 and the circuit assembly area 23 to complete the current work task, the unit workbenches 1 located in the corresponding work areas are assembled in series, and then Figure 1 Of course, in the actual production process, the assembly form of the production line can be flexibly adjusted according to the different assembly requirements of the specific models of vacuum cleaners produced, thereby dividing the assembly areas into different parts, so as to meet the production needs of different models of vacuum cleaners.

[0028] The vacuum cleaner assembly production line designed in this embodiment can utilize the unit workbench 1 to freely assemble into various assembly line forms 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, and has better production flexibility. It can also utilize the cooperation of the clamping device 3 and the conveying device 5 to realize automatic grasping of the vacuum cleaner parts 14, thereby saving the waiting time of the operator, solving the problem that the existing production line cannot smoothly transport parts and the efficiency of obtaining parts is low, and it is not convenient to flexibly modify the production line, which can effectively improve production efficiency.

[0029] Example 2: Please refer to Figures 2 to 6On the basis of the first embodiment, the conveyor belt 501 is provided with matching slideways 502 on the left and right sides of the corresponding racks 503, and the mounting frame 407 is fixedly provided with guide rails 403 that slide along the matching slideways 502 and are used to prevent the conveyor belt 501 from escaping from the upper and lower ends of the support shaft 401. The front and rear ends of the conveyor platform 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, as well as the friction between the conveyor belt 501 and the support shaft 401, if the conveyor belt 501 cannot fit on the surface of the support shaft 401, the driven wheel 404 will also be unable to mesh correctly with the rack 503. Therefore, the conveyor belt 501 will not be able to move correctly at this time. By adding the guide rail 403, the sliding effect of the guide rail 403 and the matching slideway 502 can be utilized to firmly press the conveyor belt 501 on the support shaft. The surface of the shaft 401 ensures that the rack 503 can be correctly engaged with the driven wheel 404, so that the main drive motor 402 can correctly drive the conveyor belt 501 to move, thereby ensuring that the entire production line can stably transport various vacuum cleaner parts 14 at a preset speed, ensuring the stability of production. In addition, supporting the end of the conveyor belt 501 by the end support shaft 24 can effectively make the two adjacent conveyor belts 501 docked with a smaller spacing, and complete the docking process with a smaller height change in the transition area of ​​the docking. Compared with the traditional docking method using a single roller, it can effectively avoid the problem of vacuum cleaner parts 14 getting stuck at this point, thereby ensuring the stable operation of the production line, further solving the problem that the existing production line cannot smoothly transport parts and the efficiency of obtaining parts is low, and it is not convenient to flexibly modify the production line, which can effectively improve production efficiency.

[0030] Example 3: Please refer to Figures 7 to 10On the basis of the second embodiment, the end of the clamping arm 306 is provided with an adaptive clamp 2 for clamping the vacuum cleaner parts 14, and the adaptive clamp 2 includes a connecting plate 201 fixedly installed with the end of the clamping arm 306, and a pair of arc frames 202 are symmetrically hingedly installed at the left and right ends of the connecting plate 201, and each arc frame 202 is symmetrically hingedly installed with a pair of arc clamping blocks 204 for clamping the vacuum cleaner parts 14 through the connecting protrusions 203. The adaptive clamp 2 designed by the present invention can better adapt to different types of vacuum cleaner parts 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 and rectangular. shaped or elliptical, that is to say, the two side surfaces for being clamped by the clamping arm 306 generally have a certain curvature. If a plane is used for clamping, it is easy for the clamping arm 306 to form a point contact with the bottom shell of the vacuum cleaner, thereby causing excessive force in the clamped area of ​​the outer wall of the bottom shell of the vacuum cleaner to deform and wear, and it is easy to rotate and shake during the clamping process. Therefore, it is necessary to ensure that the clamping arm 306 can clamp the bottom shell of the vacuum cleaner in the form of surface contact. Providing an adaptive clamp 2 on the clamping arm 306 can solve this problem. When the vacuum cleaner component 14 has a curved clamp block 204 that contacts before other areas, the curved clamp block that fits with the area 204 will rotate under the push of the force, and the force will be transmitted to the arc frame 202 so that the arc frame 202 will also rotate, so that the arc clamping block 204 at the other end of the arc frame 202 is pushed out and contacts with the corresponding area of ​​the vacuum cleaner component 14, so that the arc frame 202 will stop rotating only when the arc clamping blocks 204 on both sides of the arc frame 202 are in contact with the vacuum cleaner component 14, thereby achieving clamping of at least two areas, and when, and the outer surface of the arc clamping block 204 can be set to 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 14 When the size of the component 14 is larger, two arc frames 202 can be used to press against the side of the vacuum cleaner component 14. At this time, since the arc frame 202 will rotate after being subjected to force, it can ensure that there will be at least one arc clamping block 204 on each arc frame 202 to clamp the outer wall of the vacuum cleaner component 14, so that the surface contact of the two areas can still be formed, thereby ensuring the clamping effect and realizing effective clamping of various vacuum cleaner components 14 required for assembling the vacuum cleaner, further solving the problem that the existing production line cannot transport components smoothly and the efficiency of obtaining parts is low, and it is not convenient to flexibly modify the production line, which can effectively improve production efficiency.
