Description

Technical Field

[0001] The invention relates to the technical field of packaging and bundling, and in particular to an assembly line type wire harness bundling station. Background Art

[0002] The assembly line wire harness wrapping table is a device used in modern industrial production for efficient wrapping of products with wire harnesses. It is particularly suitable for the wire harness wrapping operations of products such as automobile assembly wire harnesses and lamp assembly wire harnesses. Through the assembly line wire harness wrapping processing, the continuous and large-scale production of wire harness wrapping can be realized, which greatly improves the efficiency of wire harness wrapping production on product assemblies. However, the existing assembly line wrapping tables still have some problems that need to be solved in the actual operation process.

[0003] The most prominent problem is that the angle of the carrier plate that carries the product assembly is difficult to adaptively adjust at different workstations. In actual wire harness wrapping operations, different workstations are responsible for different types of wrapping operations, which causes each product assembly to be gradually moved to different workstations for wrapping by different staff members. Affected by different processes and operating habits, the optimal tilt angles of the carrier plates required by staff members at different workstations are different. However, in actual operations, the carrier plate needs to drive the product assembly to move between different workstations. In order to ensure the stability of the carrier plate in movement between each workstation, the existing carrier plates are usually designed with fixed angles, or although they have adjustable functions, the adjustment process is cumbersome, and each time they move to a different workstation, the staff needs to manually adjust them. This causes the staff to often need to operate in an unnatural posture when performing wrapping operations, which is not only inconvenient to operate, but also very easy to cause fatigue. If the staff members are in this working state for a long time, their work efficiency will be significantly reduced, thereby affecting the work efficiency of the entire wire harness production line.

[0004] Therefore, an assembly line type wire harness wrapping station is proposed to solve some problems existing in the above-mentioned prior art. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that in the actual use of the assembly line type wire harness wrapping table in the prior art, after the carrying platform is moved to different workstations, it is difficult to adaptively adjust to the optimal angle, which causes the workers to easily get tired when wrapping the wire harness for a long time, affecting the production efficiency, and proposes an assembly line type wire harness wrapping table.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, by uniformly surrounding and fixing the bearing platforms corresponding to the working stations and the loading and unloading stations on the chain, with the rotation of the chain, numerous bearing platforms can be driven to transfer orderly among the various stations, forming a pipeline-style wire harness binding mode. At the same time, by hinging the upper end of the bearing plate to the rod frame and installing the adjustable support mechanism corresponding to the working station at the bottom of the ring track, when the bearing platform moves to different working stations, it will be guided and supported by the first sliding rod and the first guide wheel in the adjustable support mechanism, and automatically deflected and adjusted to the corresponding inclination angle. The operation is flexible and convenient, which is conducive to ensuring that the staff can perform the wire harness binding operation at the most suitable angle and is beneficial to improving the overall operation efficiency.

[0019] 2. In the present invention, second guide wheels are arranged on both the front and rear sides of each first guide wheel, and a belt is rolled and sleeved on the first guide wheel and the second guide wheels. With the guidance of the first guide wheel and the second guide wheels, the belt forms a V-shaped inclined structure at the positions on both the front and rear sides of the first guide wheel. This enables the belt to better guide the carrier plate in the loading platform during the process of moving and transferring to different working stations, thereby facilitating the improvement of the smoothness of the adaptive adjustment of the device to the carrier plate moving to different working stations. At the same time, through the elastic support of the straight spring for the second sliding rod and the rolling guidance of the third guide wheel, when the first sliding rod slides and adjusts, the belt can be adaptively tensioned, which is beneficial to ensuring the stability during the operation of the adjustable support mechanism;

[0020] 3. In the present invention, the waste chute is rotatably connected to the bottom of the carrier plate, which is convenient for the staff to directly put the waste into the waste chute during the bandaging process. The baffle is rotatably installed at the bottom of the waste chute, and aggregate bins are provided at the front and rear ends of the base. The first electromagnet that can magnetically attract the baffle is installed in the aggregate bins. After the loading platform moves to the loading and unloading station, the baffle automatically turns downward and opens under the magnetic attraction of the first electromagnet, gathering the waste generated by each loading platform in the aggregate bins, which is convenient for collection and treatment, and the waste cleaning process will not interfere with the staff in the working station, which is beneficial to improving the working efficiency;

[0021] 4. In the present invention, the limiting rod is rotatably installed on the fixed block fixed on one side of the carrier plate, and the second electromagnet that can magnetically attract the limiting rod is fixedly installed on the support rod in the loading and unloading station. After the loading platform enters the loading and unloading station, the limiting rod deflects outward under the magnetic attraction of the second electromagnet, automatically releasing the restriction on the product assembly carrier plate in the groove of the carrier plate. After the loading platform moves out of the loading and unloading station, with the elastic support of the torsion spring, the limiting rod resets to restrict the product assembly carrier plate, automatically unlocking and locking, which is convenient to operate and can effectively ensure the stability of the device during the progressive bandaging of the product assembly for the wire harness.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] Embodiment: This embodiment provides a pipeline-type wire harness wrapping table. Refer to Figure 1 - Figure 12 , specifically, it includes a longitudinally arranged base 1. A bracket 101 is fixedly installed on the top of the base 1. Vertical rotating shafts 102 are rotatably installed at the front and rear ends of the bracket 101. Sprockets 103 are fixedly installed on the rotating shafts 102. A chain 104 is sleeved and driven between two corresponding front and rear sprockets 103. A servo motor 105 is fixedly installed in the base 1, and the drive shaft of the servo motor 105 is fixedly connected to one of the brackets 101. A ring rail 2 sleeved on the bottom of the bracket 101 is fixed on the base 1. A plurality of evenly distributed working stations are arranged on both the left and right sides of the base 1. One feeding and discharging station is arranged at each of the front and rear ends of the base 1. Each working station and the feeding and discharging station correspond to a carrying platform. The carrying platform includes a rod frame 3 fixedly connected to the chain 104. A carrying plate 303 is hinged to the side of the rod frame 3 away from the chain 104. A groove is formed on the side of the carrying plate 303 away from the chain 104, and a product assembly carrier plate 304 is placed in the groove. Adjustable support mechanisms corresponding to a plurality of working stations are installed on both the left and right sides of the ring rail 2. The adjustable support mechanism includes a first sliding rod 4 slidably connected horizontally to the bottom of the ring rail 2. A first guide wheel 401 is rotatably installed at the end of the first sliding rod 4 close to the carrying plate 303. A first screw rod 402 parallel to the first sliding rod 4 is fixedly installed at the bottom of the first sliding rod 4. A screw barrel 403 rotatably installed below the ring rail 2 is threadedly connected to the first screw rod 402.

[0045] When the device is in use, after the servo motor 105 is powered on and started, it can drive the rotating shaft 102 connected to its drive shaft to rotate, drive the sprocket 103 to rotate, and then drive the chain 104 to rotate. Through the rotation of the chain 104, a large number of carrying platforms can be driven to move orderly between a plurality of working stations and the feeding and discharging stations. A worker is arranged at each working station for wire harness wrapping operations. The workers at each working station only perform one type of wrapping operation. The chain 104 drives the carrying platform to gradually pass through a plurality of working stations, so that a large number of different types of wire harness wrapping operations on the product assembly are gradually completed, forming a pipeline-type wrapping operation, which can effectively improve the orderliness and efficiency of wire harness wrapping on the product assembly.

[0046] During the actual operation process, the product assembly to be wire-harnessed is fixed on the product assembly carrier plate 304. Then, the product assembly carrier plate 304 is placed in the groove opened on the carrier plate 303 in the loading and unloading station. Subsequently, the product assembly carrier plate 304 with the product assembly fixed thereon is gradually moved to each different operation station for wire-harness wrapping processing. This device can operate in two different modes. When the number of wire-harness wrapping steps of different types on the product assembly is greater than the number of operation stations on either side, the device only sets one of the loading and unloading stations as the loading and unloading operation for the product assembly, so that there is only one wrapping path in the device. Different types of progressive wrapping operations are gradually completed along the rotation direction of the chain 104. Finally, the above-mentioned loading and unloading operation is realized at the loading and unloading station, and after surrounding a circle, the product is unloaded from the above-mentioned loading and unloading station.

[0047] When the number of wire-harness wrapping steps of different types on the product assembly is less than the number of operation stations on either side, the device can simultaneously enable the front and rear loading and unloading stations as the loading and unloading operations for the product assembly, so that there are two wrapping paths in the device at the same time. Taking the middle perspective as the reference standard, the product assembly is loaded onto the bearing platform from the front loading and unloading station. Then, the chain 104 drives the bearing platform to rotate counterclockwise. After gradually passing through multiple operation stations on the right side, the wire-harness wrapping processing is gradually completed by the staff at the corresponding operation stations. Finally, it is taken out through the rear loading and unloading station. This is the first wrapping path. Similarly, the product assembly can be loaded onto the bearing platform from the rear loading and unloading station. Then, driven by the counterclockwise rotation of the chain 104, it gradually passes through multiple operation stations on the left side, and the wire-harness wrapping processing is gradually completed by the staff at the corresponding stations. Finally, it is taken out through the front loading and unloading station. This is the second wrapping path. In this mode, the two wrapping paths operate synchronously, which is suitable for the situation where there are fewer wire-harness wrapping steps on the product assembly. Figure 7 During the wrapping processing, since the bearing platform is driven by the chain 104 to move around, the positions of the bearing platforms do not remain unchanged. In the actual use process, the positions of the bearing platforms will gradually move according to the processing steps, pass through different operation stations, and be used by different staff. Since the body shapes and operating habits of each staff are different, the inclination angles of the staff using the carrier plate 303 at different stations are different. In the prior art, due to the continuous movement of the bearing platform, the carrier plate 303 is not convenient for adaptive attitude adjustment according to the daily use habits of the staff at different operation stations, so that many staff are prone to discomfort and fatigue due to the unified posture during the long-term wire-harness wrapping operation, which will affect the labor burden and operation efficiency of the staff.

[0048]

[0049] ​When the device is in operation, the first slide bar 4 for adjusting the tilt attitude of the carrier plate 303 is installed below the loop track 2 corresponding to each working station. During the adjustment process by the staff, the screw cylinder 403 can be driven to rotate. By means of the threaded connection between the screw cylinder 403 and the first screw 402, the first screw 402 is driven to drive the first slide bar 4 to move left and right, so as to adjust the position of the first guide wheel 401 rotatably installed at the end of the first slide bar 4. After the carrier platform moves to different working stations, through the rolling guidance of the first guide wheel 401 and the support of the first slide bar 4, the tilt angle of the carrier plate 303 moving to the corresponding area of the working station will be adaptively adjusted. The staff only needs to adjust the first slide bar 4 and the first guide wheel 401 corresponding to their own working station to a suitable position, and then the carrier plate 303 in the carrier platform moving to this working station will automatically adjust to a suitable tilt angle for itself, so that the product assembly on the product assembly carrier plate 304 placed in the groove on the carrier plate 303 faces itself at a suitable tilt angle, which can effectively improve the comfort of the staff during long-term wire harness binding operations, and thus is beneficial to improving the operation efficiency.

[0050] In the specific implementation process, as Figure 7 shown, the front and rear ends of the base 1 are set as frustum structures 106. The rotation trajectories of the carrier plate 303 at the front and rear ends of the base 1 are located above the inner side of the frustum structure 106. When the device is in use, by setting the front and rear ends of the base 1 as frustum structures 106, when the carrier platform moves and adjusts its position at the front and rear ends of the base 1, the carrier platform will not protrude outside the frustum structure 106, which can avoid collisions with surrounding personnel or objects during the rotation and movement of the carrier platform at the front and rear ends of the base 1, and can effectively improve the safety and stability during the operation of the device. At the same time, no adjustable support mechanism is set at the positions corresponding to the front and rear two loading and unloading stations, so that when the carrier platform rotates and adjusts at the front and rear ends of the base 1, under the self-weight of the carrier plate 303, the lower end of the carrier plate 303 will further approach the rod frame 3, which can not only reduce the coverage area of the movement trajectory of the carrier plate 303 during the rotation of the carrier platform, but also reduce the outer diameter of the frustum structure 106, which is beneficial to reducing the floor area of the device and further improving the safety during the use of the device.

[0051] In the specific implementation process, as Figure 2 、 Figure 8 and Figure 9As shown in the figure, sprockets 103 are fixedly installed at both the upper and lower ends of each rotating shaft 102. A chain 104 is sleeved between the sprockets 103 fixed at the upper ends of the front and rear rotating shafts 102 in a driving manner, and a chain 104 is also sleeved between the sprockets 103 fixed at the lower ends of the front and rear rotating shafts 102 in a driving manner. The rod frame 3 is vertically arranged and fixedly connected to the upper and lower chains 104. The bottom end of the rod frame 3 is provided with an L-shaped structure. A first roller 301 that rolls and fits against the inner side of the ring rail 2 is rotatably installed at the bottom end of the rod frame 3, and a second roller 302 that rolls and fits against the top of the ring rail 2 is rotatably installed at the bottom end of the rod frame 3.

[0052] When the device is in use, during the rotation of the rotating shaft 102, the sprockets 103 fixed at its upper and lower ends will be driven to rotate synchronously, thereby driving the upper and lower chains 104 to rotate synchronously. Since the upper and lower chains 104 are fixedly connected to the upper and lower ends of each rod frame 3, this can effectively improve the stability of the chain 104 driving the rod frame 3 to move. At the same time, by rotatably installing the first roller 301 at the bottom of the rod frame 3 and making the first roller 301 roll and fit against the inner side of the ring rail 2, and by rotatably installing the second roller 302 at the lower end of the rod frame 3 and making the second roller 302 roll and support against the top of the ring rail 2, this can effectively improve the supporting force provided below during the process of the rod frame 3 being driven to move by the chain 104. With the mutual cooperation, the stability of the carrying platform being driven to move by the upper and lower chains 104 can be further improved.

[0053] In the specific implementation process, as Figure 4 、 Figure 5 and Figure 11 shown, second guide wheels 404 are arranged on both the front and rear sides of each first guide wheel 401, and the second guide wheels 404 are rotatably installed on the left and right sides of the ring rail 2. A belt 405 is sleeved between the numerous first guide wheels 401 and second guide wheels 404 in a driving manner, and the belt 405 is rolled and sleeved on the side of the first guide wheel 401 close to the bearing plate 303. The left and right sides of the belt 405 form a W-shaped structure under the support of the numerous first guide wheels 401 and second guide wheels 404. When the device is in use, since a second guide wheel 404 is arranged on both the front and rear sides of each first guide wheel 401, and a belt 405 is sleeved on all the first guide wheels 401 and second guide wheels 404 in a driving manner, under the guidance of the second guide wheel 404, the belt 405 forms an inclined structure on the front and rear sides of the first guide wheel 401. This enables the bearing plate 303 in the carrying platform to be better guided by the inclined belt 405 during the process of moving and transferring to different working stations, so that when the bearing plate 303 moves to different working stations, it can be more smoothly supported by the first slide bar 4 and the first guide wheel 401 corresponding to different working stations, thereby effectively improving the smoothness of the adaptive adjustment of the device for the bearing plate 303 moving to different working stations.

[0054] In the specific implementation process, such as Figure 4 - Figure 5 , Figure 8 and Figure 11 shown, longitudinal second slide bars 406 and third slide bars 407 are slidably inserted on both the front and rear sides of the bracket 101, and the ends of the second slide bars 406 and the third slide bars 407 are fixedly connected. A third guide wheel 408 is rotatably installed at one end of the second slide bar 406 close to the belt 405, and the third guide wheel 408 rolls and fits on the belt 405. A straight spring 409 for elastically supporting the second slide bar 406 is movably sleeved on the outer side of the second slide bar 406. V-shaped structures are formed on both the front and rear sides of the belt 405 under the support of the third guide wheel 408. When the device is in use, under the elastic support of the straight spring 409, the third guide wheel 408 tightly presses on the belt 405, making the whole belt 405 in a taut state, which can prevent the belt 405 from falling off from a plurality of first guide wheels 401 and second guide wheels 404. When the positions of the first slide bar 4 and the first guide wheel 401 corresponding to different working stations are changed by the staff, the attitude of the belt 405 synchronously changes under the pushing of the first guide wheel 401. At this time, with the elastic support of the straight spring 409, the third guide wheel 408 will perform an adaptive tensioning operation on the belt 405, so that the belt 405 still maintains a stable state when the first guide wheel 401 is adjusted at different positions, which can effectively ensure the stability of the device during actual use.

[0055] In the specific implementation process, such as Figure 4 , Figure 6 and Figure 9 shown, a vertically arranged first transmission shaft 5 and a horizontally arranged second transmission shaft 501 are rotatably installed in the area corresponding to each working station on the base 1. The second transmission shaft 501 is located below the first transmission shaft 5. First bevel gears 502 are fixed at both the upper and lower ends of the first transmission shaft 5. A second bevel gear 503 meshing with the upper first bevel gear 502 is fixed on the screw barrel 403. A third bevel gear 504 meshing with the lower first bevel gear 502 is fixed on the second transmission shaft 501. The second transmission shaft 501 movably penetrates to the corresponding working station and is fixedly installed with a crank 505. When the device is in use, when the staff needs to drive the screw barrel 403 to rotate to adjust the positions of the first slide bar 4 and the first guide wheel 401, the staff can hold the corresponding crank 505 on their own working station and rotate it. By rotating the crank 505, the second transmission shaft 501 is driven to rotate. With the engagement of the third bevel gear 504 and the lower first bevel gear 502, the first transmission shaft 5 is driven to rotate. Then, with the engagement of the second bevel gear 503 and the upper first bevel gear 502, the screw barrel 403 is driven to rotate, transmitting the rotational power to the corresponding screw barrel 403, realizing the convenient adjustment of the positions of the first slide bar 4 and the first guide wheel 401, and the operation is convenient and efficient.

[0056] In the specific implementation process, such as Figure 1 , Figure 3 , Figure 8 and Figure 9 show, a waste chute 305 is rotatably connected to the bottom of the carrier plate 303, and a baffle 306 is rotatably installed at the bottom of the waste chute 305. A torsion spring is installed at the rotation connection of the waste chute 305 and the baffle 306. The baffle 306 is blocked at the bottom of the waste chute 305 under the elastic support of the torsion spring. Aggregate bins 6 corresponding to the waste chute 305 are provided on the front and rear sides of the base 1, and a first electromagnet 601 is installed in the aggregate bin 6. The baffle 306 is made of a magnetically conductive material. When the device is in use, during the wiring harness wrapping process, the waste cut by each worker during wrapping can be directly put into the waste chute 305 rotatably installed below the carrier plate 303, which is convenient and handy to operate. When the carrying platform moves to the front and rear loading and unloading stations, in this state, the first electromagnet 601 in the aggregate bin 6 is located below the baffle 306. After the baffle 306 is powered on and started, it can generate magnetic attraction to the baffle 306, so that the baffle 306 overcomes the elastic support of the torsion spring and flips downward, so that the bottom of the waste chute 305 is in a through state, and the waste collected in the waste chute 305 can directly fall downward into the aggregate bin 6 to complete the collection of waste, which is convenient for the workers to collect and process the waste uniformly after the processing is completed. Since the waste will eventually be collected in the aggregate bin 6, and the aggregate bin 6 is located at the front and rear ends of the base 1, this enables other workers not to interfere with the wrapping operations of the workers in the operation station during the process of cleaning the waste in the aggregate bin 6, which is beneficial to improving the operation efficiency.

[0057] In the specific implementation process, such as Figure 1 , Figure 3 , Figure 7 and Figure 12 show, a fixed block 307 is fixedly installed above one side of the carrier plate 303, and a limiting rod 308 is rotatably installed on the fixed block 307. A limiting block 309 is fixed on the limiting rod 308. A torsion spring is installed at the rotation connection of the limiting rod 308 and the fixed block 307. The limiting rod 308 is clamped outside the product assembly carrier plate 304 under the elastic support of the torsion spring. Support rods 7 are fixedly erected on the outer sides of the front and rear ends of the base 1, and a second electromagnet 701 corresponding to the limiting rod 308 is fixedly installed on the support rods 7. The limiting rod 308 is made of a magnetically conductive material.

[0058] During the use of the device, when the loading platform is at the loading and unloading station, after the second electromagnet 701 installed at the end of the support rod 7 is powered on and starts, it will generate a magnetic attraction on the limit rod 308 on the loading platform in the loading and unloading station, causing the limit rod 308 to overcome the elastic support of the torsion spring. The upper end of the limit rod 308 deflects towards the second electromagnet 701, so that the limit rod 308 releases the restriction on the product assembly carrier plate 304 in the groove on the bearing plate 303. Then, the staff can perform the loading and unloading operations of the product assembly carrier plate 304. When the loading platform leaves the loading and unloading station driven by the chain 104, due to the distance of the limit rod 308, it is difficult for the magnetic attraction generated on the second electromagnet 701 to pull the above-mentioned limit rod 308. Under the elastic reset of the torsion spring, the limit rod 308 deflects and resets, and re-fastens on the product assembly carrier plate 304 to restrict the product assembly carrier plate 304, so that the product assembly carrier plate 304 can be stably maintained in the groove opened on the bearing plate 303 during movement. The limit rod 308 automatically deflects and opens at the loading and unloading station, and automatically fastens on the product assembly carrier plate 304 to restrict it during the movement of the loading platform, which can effectively ensure the stability of the device when transporting the product assembly for wire harness step-by-step wrapping, and the operation is convenient.

[0059] Specifically, the working principle and operation method of the present invention are as follows:

[0060] The servo motor 105 is powered on and starts, driving the rotating shaft 102 to drive the sprocket 103 to rotate, and then driving the chain 104 to rotate. Through the rotation of the chain 104, the carrying platform is driven to move orderly between the feeding and discharging stations and each working station. In the feeding and discharging station, after the second electromagnet 701 is powered on and starts, the magnetic attraction on the limiting rod 308 causes the limiting rod 308 to deflect outwards, releasing the restriction on the product assembly carrier plate 304. The staff places the product assembly carrier plate 304 with the fixed product assembly in the groove opened on the carrier plate 303 at the feeding and discharging station. Then, driven by the chain 104, the carrying platform drives the product assembly to pass through many working stations along the way one by one, facilitating the staff at each working station to gradually complete the bandaging operation of the wiring harness on the product assembly. After the carrying platform leaves the feeding and discharging station, the magnetic attraction on the second electromagnet 701 cannot act on the limiting rod 308, and the limiting rod 308 resets under the elastic support of the torsion spring, restricting the product assembly carrier plate 304 loaded in the groove on the carrier plate 303 again. The waste generated by the staff's bandaging and cutting is directly put into the waste chute 305 rotatably connected below the carrier plate 303. When the carrying platform moves back to the feeding and discharging station, the staff takes out the product assembly after the wiring harness is bandaged. At the same time, the baffle 306 flips under the magnetic attraction of the first electromagnet 601 in the lower aggregate bin 6, and the waste in the waste chute 305 converges in the aggregate bin 6, facilitating unified cleaning. The staff at the working station can hold the crank 505 and rotate it to drive the screw barrel 403 to rotate. By means of the thread engagement between the screw barrel 403 and the first screw 402, the positions of the first slide bar 4 and the first guide wheel 401 are adjusted. During the movement of the carrying platform, with the inclined guidance of the belt 405, after the carrying platform moves into place, it will be supported by the first slide bar 4 and the first guide wheel 401 and automatically adjusted to the posture suitable for the staff at the corresponding working station, improving the comfort of the staff during the wiring harness bandaging process and being beneficial to improving the overall processing efficiency.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
