Description

Technical Field

[0001] The present invention relates to the technical field of automobile production and assembly, and particularly relates to a method, system, storage medium and device for assembling vehicles with a spreader follow-up plate chain. Background Art

[0002] With the rapid development of industrial automation, the transformation and upgrading of automobile assembly has also been carried out. The assembly of automobile products is one of the most important technological processes in the manufacturing process of automobile products.

[0003] In the prior art, a lift and friction wheel are usually used to transport vehicle parts and then the parts of the vehicle are assembled separately. The lift and friction wheel can only manually control the transportation and assembly of vehicle parts, and cannot achieve automatic control. Moreover, the lift and friction wheel can only assemble the vehicle in a stopped state and cannot perform synchronous assembly online, resulting in too long automobile assembly time and low assembly efficiency. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a method, system, storage medium and device for assembling vehicles with a spreader follow-up plate chain, so as to solve the problems in the background art that the lift and friction wheel for vehicle assembly cannot achieve automatic control and cannot perform synchronous assembly online, resulting in too long automobile assembly time and low assembly efficiency.

[0005] On the one hand, the present invention provides a method for assembling vehicles with a spreader follow-up plate chain, which is applied to a system for assembling vehicles with a spreader follow-up plate chain. The system for assembling vehicles with a spreader follow-up plate chain includes a plurality of spreaders, a circular track and a plate chain located above the circular track. The plurality of spreaders move on the circular track, and load carriers are provided on both the spreaders and the plate chain. The method includes:

[0006] Obtain a spreader follow-up request, and control the spreader and the plate chain to enter the operating state according to the vehicle follow-up assembly request;

[0007] Judge whether the current spreader reaches the assembly area of the circular track;

[0008] If the current spreader reaches the assembly area of the circular track, obtain the running speed of the current spreader and the running speed of the plate chain, compare the running speed of the current spreader with a first preset speed, and compare the running speed of the plate chain with a second preset speed to judge whether they are consistent;

[0009] If the running speed of the current spreader is consistent with the first preset speed, and the running speed of the plate chain is consistent with the second preset speed, control the load carriers on the current spreader and the plate chain to perform vehicle assembly.

[0010] The method for assembling a vehicle with a hanger follower plate chain in the present invention is to set multiple moving hangers on a circular track, set a plate chain on the circular track, and set load-bearing objects required for vehicle installation on the hanger and the plate chain respectively. When the hanger reaches the assembly area, it is judged whether the running speed of the hanger and the running speed of the plate chain are consistent with the preset speed. If they are consistent, the assembly is automatically carried out, so as to achieve the purpose of automatic control of vehicle assembly. Moreover, during the synchronous operation of the hanger and the plate chain, vehicle assembly can be completed simultaneously, saving vehicle assembly time and thus improving vehicle assembly efficiency.

[0011] Further, after the step of comparing the running speed of the current hanger with the first preset speed and comparing the running speed of the plate chain with the second preset speed to judge whether they are consistent, it further includes:

[0012] If the running speed of the current hanger is inconsistent with the first preset speed, or the running speed of the plate chain is inconsistent with the second preset speed, then it is judged whether the running speed of the current hanger is greater than the running speed of the plate chain;

[0013] If the running speed of the current hanger is less than the running speed of the plate chain, then the speed of the current hanger is increased to the third preset speed, and the third preset speed is greater than the second preset speed.

[0014] Further, after the step of judging whether the running speed of the current hanger is greater than the running speed of the plate chain, it further includes:

[0015] If the running speed of the current hanger is greater than the running speed of the plate chain, then the speed of the current hanger is reduced to the fourth preset speed, and the fourth preset speed is less than the second preset speed.

[0016] Further, after the step that the current hanger reaches the assembly area of the circular track, it further includes:

[0017] Obtain the actual height between the current hanger and the plate chain, and judge whether the actual height is greater than the preset height;

[0018] If the actual height is greater than the preset height, then control the current hanger to perform a descending action so that the actual height between the current hanger and the plate chain reaches the preset height.

[0019] Further, there are multiple continuous and uninterrupted circular barcodes on the circular track, and a barcode reader is provided on the hanger. The method further includes:

[0020] Read the circular barcode on the circular track according to the barcode reader on the hanger, and determine the position of the hanger on the circular track according to the read circular barcode.

[0021] Further, the method further includes:

[0022] Calculate the spacing between multiple spreaders based on the positions of each spreader on the circular track, and determine whether the spacing is greater than a preset spacing.

[0023] If so, adjust the running speeds between the multiple spreaders so that the spacing is less than the preset spacing.

[0024] Furthermore, if the running speed of the current spreader is consistent with the first preset speed, and the running speed of the plate chain is consistent with the second preset speed, then after controlling the current spreader and the load on the plate chain to perform the steps of vehicle assembly, it further includes:

[0025] Judge whether the vehicle assembly is completed.

[0026] If not, control the current spreader and the plate chain to stop moving forward, control the spreader to perform a descending action, and perform vehicle assembly.

[0027] On the other hand, the present invention provides a vehicle assembly system with a spreader following a plate chain, and the system includes:

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] The method for assembling a vehicle with a spreader follower plate chain in the embodiment of the present invention is applied to a system for assembling a vehicle with a spreader follower plate chain. As Figures 4-6 shown, the system includes a spreader a, an annular track b, and a plate chain d. The spreader a runs on the annular track, and the plate chain d is located above the annular track b.

[0047] The lifting device includes a traveling motor 1 and a friction wheel 2. The traveling motor 1 drives the friction wheel 2, and the friction force between the friction wheel 2 and the track b enables the lifting device to travel on the circular track b. A circular sliding contact wire 3 is installed on the circular track, and the circular sliding contact wire 3 is used to carry the power input of all electrical facilities such as the lifting device a. There are at least four circular sliding contact wires 3.

[0048] A code reader 4 is also installed on the lifting device a. A circular continuous and uninterrupted circular bar code is installed on the circular track b, and each bar code corresponds to a different position on the circular track. The front of the code reader 4 faces the circular track b and is used to scan the circular bar code on the circular track b. The code reader 4 scans and reads data to obtain the position of the lifting device a on the circular track.

[0049] A scissor-type mechanical lifting structure 5 is installed at the lifting part of the lifting device a. The scissor-type mechanical lifting structure 5 is connected to a lower frame body below, and the lower frame body is used to fix the carrier y for the vehicle object, such as a vehicle frame. A support frame 8 is installed on the plate chain d, and the surface of the support frame 8 is fixed with polyurethane and then screwed to the plate chain d. The carrier y is placed on the support surface of the plate chain d to fix the carrier so that it is not easily loosened and shaken. The carriers placed on the plate chain include various parts of the vehicle. A travel switch 9 is installed at the vehicle assembly station c of the plate chain d, and the signal of the travel switch 9 is connected to the programmable logic controller; an electrical cabinet 6 is installed on the lifting device a. In addition to installing an air switch, a contactor and a relay, the electrical cabinet 6 also installs a frequency converter, and the frequency converter is used to perform frequency conversion processing on the traveling motor 1 on the lifting device. The frequency conversion range of the traveling motor 1 is within 0 - 50HZ.

[0050] In the lifting device accompanying plate chain vehicle assembly system in the embodiment of the present invention, multiple sets of PLCs (1756 and 1769) are networked, using the EtherNet / IP protocol, an industrial-grade wireless router and a wireless remote control. The ladder diagram program is modified using RSlogix5000, and the touch screen screen is modified using FactoryTalk View Studio to achieve intelligent linkage of the EMS lifting device in the automotive production line under the wireless network, solve bottlenecks, save energy and increase efficiency, and save the problem of plate chain stop line assembly.

[0051] Embodiment 1

[0052] Please refer to Figure 1 , which shows the method for assembling a vehicle with a lifting device accompanying a plate chain in the first embodiment of the present invention, including steps S11 - S14.

[0053] S11. Obtain a request for the lifting device to accompany, and control the lifting device and the plate chain to enter the operating state according to the request for vehicle accompanying assembly.

[0054] Press the travel switch of the system. The system performs the assembly process. The spreader and the plate chain enter the operating state. Multiple spreaders start to operate on the circular track. The plate chain and the spreaders advance at their respective preset operating speeds, and the operating speeds of the plate chain and each spreader are monitored in real time. The plate chain and the spreaders are controlled by the motors on the plate chain and on each spreader to operate at the set speeds.

[0055] Among them, the operating speed of the spreader in the assembly area of the circular track changes from fast to slow and then to a stop action. A collision distance is maintained between all spreaders to ensure that two load-carrying spreaders will not collide with each other; the assembly area refers to the area under the plate chain for assembly.

[0056] It can be understood that the circular bar code on the circular track is read by the code reader on the spreader, and the position of the spreader on the circular track is determined according to the circular bar code read by the spreader. Multiple distances between the spreaders are calculated based on the positions of each spreader on the circular track, and it is judged whether each distance is greater than the preset distance. If so, there is a collision risk between the spreaders, and the operating speed of the spreader with a smaller distance is adjusted accordingly to make the distance less than the preset distance.

[0057] Optionally, when the distance between the spreaders is less than the preset distance, the operating speed of the latter spreader is reduced. When the distance is greater than the preset distance, the operating speed is adjusted to the first preset speed.

[0058] S12. Judge whether the current spreader has reached the assembly area of the circular track.

[0059] If the current spreader has reached the assembly area of the circular track, step S13 is executed.

[0060] After the spreader operates on the circular track, it is judged whether the current spreader has reached the assembly area of the circular track, where the assembly area is the area for vehicle assembly, and the area where the circular track coincides with the plate chain in parallel is the assembly area.

[0061] S13. Obtain the operating speed of the current spreader and the operating speed of the plate chain, compare the operating speed of the current spreader with the first preset speed, and compare the operating speed of the plate chain with the second preset speed to judge whether they are consistent.

[0062] If the operating speed of the current spreader is consistent with the first preset speed and the operating speed of the plate chain is consistent with the second preset speed, step S14 is executed.

[0063] S14. Control the current spreader and the load on the plate chain to perform vehicle assembly.

[0064] In this embodiment, during the operation of the lifting device and the plate chain, the speed of the lifting device is slightly less than that of the plate chain. According to different assembly requirements, the running speeds of the plate chain and the lifting device can be automatically adjusted. During assembly, it is necessary to assemble according to the preset running speeds of the lifting device and the plate chain to ensure the safety and reliability of the assembly process. If there are differences between the running speeds of the plate chain and the lifting device and the preset speeds during the assembly process, the load on the plate chain and the load under the lifting device will not be accurately matched, resulting in errors in the assembly process.

[0065] When the lifting device reaches the assembly area, obtain the running speed of the current lifting device under the plate chain and the running speed of the plate chain, and determine whether the running speed of the lifting device is consistent with the first preset speed and whether the running speed of the plate chain is consistent with the second preset speed. The first preset speed corresponds to the assembly speed of the lifting device, and the second preset speed is the assembly speed of the plate chain. In this embodiment, the first preset speed is less than the second preset speed, that is, the running speed of the lifting device is controlled to be lower than that of the plate chain to facilitate other assembly operations on the load on the lifting device during its operation.

[0066] When it is determined that the running speeds of the current lifting device and the plate chain are both consistent with the preset speeds, operate the pendant remote control to execute the lowering action of the load of the lifting device, so that the load of the lifting device descends to a height that can be reasonably matched with the load on the plate chain for installation, and while descending, control the load descending from the current lifting device and the load on the load-bearing plate chain to complete the assembly at the assembly station. When the vehicle is assembled, stop the lowering action of the current lifting device and raise the load on the lifting device to the initial height, and continue to run on the circular track.

[0067] In summary, the method for assembling a vehicle with a lifting device following a plate chain in the above embodiments of the present invention includes arranging a plurality of moving lifting devices on a circular track, arranging a plate chain on the circular track, and respectively arranging loads required for vehicle installation on the lifting device and the plate chain. When the lifting device reaches the assembly area, determine whether the running speeds of the lifting device and the plate chain are consistent with the preset speeds. If they are consistent, automatic assembly is performed to achieve the purpose of automatic control of vehicle assembly. Moreover, the lifting device and the plate chain can complete vehicle assembly simultaneously during synchronous operation, saving vehicle assembly time and thus improving vehicle assembly efficiency.

[0068] Embodiment 2

[0069] Please refer to Figure 2 , which shows the method for assembling a vehicle with a lifting device following a plate chain in the second embodiment of the present invention, including steps S21 - S29.

[0070] S21. Obtain the request for the lifting device to follow, and control the lifting device and the plate chain to enter the running state according to the request for vehicle assembly following.

[0071] Press the system switch, and the system starts the vehicle assembly process. The spreader and the plate chain enter the following state. You can also turn off the switch by yourself to stop the following of the spreader. When the spreader and the plate chain enter the following state, multiple spreaders start to run on the circular track. The plate chain and the spreader on each spreader advance at their respective preset running speeds, and the running speeds of the plate chain and each spreader are monitored in real time. The plate chain and the spreader are controlled by the motor on the plate chain to run at the set speed.

[0072] Among them, the running speed of the spreader in the assembly area of the circular track changes from fast to slow and then to a stop action. A collision distance is maintained between all spreaders to ensure that two load-bearing spreaders will not collide with each other; the assembly area refers to the area where assembly is carried out below the plate chain.

[0073] It can be understood that the circular bar code on the circular track is read by the reader on the spreader, and the position of the spreader on the circular track is determined according to the circular bar code read by the spreader. Multiple distances between spreaders are calculated based on the position of each spreader on the circular track, and it is judged whether each distance is greater than the preset distance. If so, there is a risk of collision between the spreaders, and the running speed of the spreader with a smaller distance is adjusted accordingly to make the distance less than the preset distance.

[0074] S22. Judge whether the current spreader reaches the assembly area of the circular track.

[0075] If the current spreader reaches the assembly area of the circular track, step S23 is executed.

[0076] After the spreader runs on the circular track, it is judged whether the current spreader reaches the assembly area of the circular track, where the assembly area is the area where the vehicle is assembled, and the area where the circular track and the plate chain are parallel and coincident is the assembly area.

[0077] S23. Obtain the running speed of the current spreader and the running speed of the plate chain, compare the running speed of the current spreader with the first preset speed, and compare the running speed of the plate chain with the second preset speed to judge whether they are consistent.

[0078] If the running speed of the current spreader is consistent with the first preset speed and the running speed of the plate chain is consistent with the second preset speed, step S24 is executed.

[0079] If the running speed of the current spreader is inconsistent with the first preset speed or the running speed of the plate chain is inconsistent with the second preset speed, step S25 is executed.

[0080] S24. Control the current spreader and the load on the plate chain to perform vehicle assembly.

[0081] In this embodiment, during the operation of the lifting device and the plate chain, the speed of the lifting device is slightly lower than that of the plate chain. According to different assembly requirements, the running speeds of the plate chain and the lifting device can be automatically adjusted. During assembly, it is necessary to assemble according to the preset running speeds of the lifting device and the plate chain to ensure the safety and reliability of the assembly process. If there are differences between the running speeds of the plate chain and the lifting device during the assembly process and the preset speeds, the load on the plate chain and the load under the lifting device will not be accurately matched, resulting in errors in the assembly process.

[0082] When the lifting device reaches the assembly area, obtain the running speed of the current lifting device under the plate chain and the running speed of the plate chain, and determine whether the running speed of the lifting device is consistent with the first preset speed, and determine whether the running speed of the plate chain is consistent with the second preset speed. The first preset speed corresponds to the assembly speed of the lifting device, and the second preset speed is the assembly speed of the plate chain. In this embodiment, the first preset speed is less than the second preset speed, that is, the running speed of the lifting device is controlled to be lower than that of the plate chain to facilitate other assembly operations on the load on the lifting device during operation.

[0083] When it is determined that the running speeds of the current lifting device and the plate chain are both consistent with the preset speeds, operate the attendant remote control to execute the lowering action of the load of the lifting device, so that the load of the lifting device descends to a height that can be reasonably matched with the load on the plate chain for installation, and control the load descending from the current lifting device and the load on the load-bearing plate chain to complete the assembly at the assembly station. When the vehicle assembly is completed, stop the lowering action of the current lifting device and raise the load on the lifting device to the initial height, and continue to run on the circular track.

[0084] S25. Determine whether the running speed of the current lifting device is greater than the running speed of the plate chain.

[0085] If the running speed of the current lifting device is less than the running speed of the plate chain, execute step S26.

[0086] If the running speed of the current lifting device is greater than the running speed of the plate chain, execute step S27.

[0087] S26. Increase the speed of the current lifting device to the third preset speed, and the third preset speed is greater than the second preset speed.

[0088] When the spreader runs on the circular track, the running speed of the spreader may be adjusted according to the operation requirements. When the current spreader reaches the assembly area, the vehicle frame on the spreader will be assembled with the carrier on the plate chain. Determine whether the running speed of the current spreader is greater than the running speed of the plate chain. If the speed of the current spreader is less than the running speed of the plate chain, the running speed of the plate chain will remain unchanged, and the running speed of the current spreader will be increased to the third preset speed, which is greater than the second speed, that is, the running speed of the current spreader is adjusted to be lower than the running speed of the plate chain, so that the running speed of the spreader catches up with the running speed of the plate chain. When the spreader is catching up with the plate chain, the carrier on the current spreader simultaneously performs a descending action and simultaneously carries out the vehicle assembly process until the vehicle assembly process is completed in the assembly area for the current spreader. Then, the running speed of the current spreader is adjusted back to the first preset speed, and the carrier on the spreader is raised to the initial height and continues to run on the circular track.

[0089] S27. Reduce the speed of the current spreader to the fourth preset speed, and the fourth preset speed is less than the second preset speed.

[0090] When the running speed of the current spreader is greater than the running speed of the plate chain, the running speed of the current spreader is further reduced to the fourth preset speed, which is lower than the second preset speed, so that the running speed of the current spreader is lower than the running speed of the plate chain. When the spreader runs in the assembly area, the carrier on the plate chain will gradually catch up with the carrier on the current spreader. At the same time, when the current spreader reduces its running speed, it performs a descending action on the carrier on the spreader, so that the carrier on the current spreader is lowered to the required height for assembling with the carrier on the plate chain, and the vehicle assembly process is carried out simultaneously. After the assembly is completed, the running speed of the current spreader is adjusted back to the first preset speed, and the carrier on the spreader is raised to the initial height and continues to run on the circular track.

[0091] S28. Determine whether the vehicle assembly is completed.

[0092] If not, execute step S29.

[0093] S29. Control the current spreader and the plate chain to stop advancing, control the spreader to perform a descending action, and carry out vehicle assembly.

[0094] When the current spreader runs to a preset distance from the end of the assembly area, determine whether the carrier on the current spreader and the carrier on the plate chain have completed vehicle assembly. If the vehicle is not assembled at the current position, control the current spreader and the plate chain to stop running, and control the current spreader to perform a descending action and continue vehicle assembly. After the assembly is completed, the running speed of the current spreader is adjusted back to the first preset speed, and the carrier on the spreader is raised to the initial height and continues to run on the circular track.

[0095] In summary, in the method for assembling a vehicle with a spreader and a follow-up plate chain in the above embodiments of the present invention, a plurality of moving spreaders are arranged on the annular track, a plate chain is arranged on the annular track, and load-carrying objects required for vehicle installation are respectively arranged on the spreader and the plate chain. When the spreader reaches the assembly area, it is judged whether the running speed of the spreader and the running speed of the plate chain are consistent with the preset speed. If they are consistent, the assembly is automatically carried out, so as to achieve the purpose of automatic control of vehicle assembly. Moreover, during the synchronous operation of the spreader and the plate chain, vehicle assembly can be completed simultaneously, saving the vehicle assembly time and thus improving the vehicle assembly efficiency.
