Description

Technical Field

[0001] The invention relates to the technical field of automobile production lines, and in particular to a control method for a vehicle interior pre-installation production line. Background Art

[0002] At present, the main forms of automobile assembly production lines include plate chain lines, sliding plate lines and friction lines. When the car body comes out of the painting production line, it is often carried by a skid, and the skid is transferred on a roller bed. Before the car body is separated from the skid, it is often necessary to pre-install the interior decoration in advance.

[0003] In the prior art, interior decoration pre-installation operations usually adopt the intermittent transfer mode: when there is no sled in the front roller bed, the rear sled is allowed to move forward quickly, and the sled stops moving after it moves into place, and the employee performs interior decoration pre-installation operations at the sled stop point. Since the intermittent transfer mode has a high transfer speed between workstations, there are safety hazards; in addition, the intermittent transfer mode has a waiting process for the vehicle to be out and in, and continuous operation is impossible, affecting the rhythm. Summary of the invention

[0004] The purpose of the present invention is to improve and innovate the shortcomings and problems existing in the background technology and provide a vehicle interior pre-assembly production line control method.

[0005] A vehicle interior pre-assembly production line control method specifically comprises the following steps:

[0006] Constructing a vehicle interior pre-installation production line; wherein the vehicle interior pre-installation production line comprises a vehicle receiving waiting transfer machine, a fast entry station, an effective operation station and a fast exit station in sequence; wherein the fast entry station, the effective operation station and the fast exit station are all provided with a front in-position detection switch and a rear in-position detection switch, and an intermediate detection switch is also provided between them;

[0007] Determine whether the front in-position detection switch and the rear in-position detection switch on the fast-entry station recognize the sled, and whether the intermediate detection switch between the fast-entry station and the effective operation station recognizes the sled; if not, control the fast-entry station to receive the sled on the waiting transfer machine at the first travel speed;

[0008] Determine whether the effective workstation is operating normally;

[0009] If so, when the front arrival detection switch on the first workstation corresponding to the effective working workstation identifies the sled, the quick entry workstation is controlled to transfer the sled to the effective working workstation at the second travel speed, and then transfers to the quick exit workstation after passing through each workstation corresponding to the effective working workstation in turn.

[0010] A further solution is that the vehicle interior pre-assembly production line further includes a rear-end connection station, each of which is provided with a front in-place detection switch and a rear in-place detection switch;

[0011] Wherein, the step of sequentially passing through each station corresponding to the effective operation station and then transferring to the quick-disconnection station comprises:

[0012] Determine whether the front in-position detection switch and the rear in-position detection switch on the rear connection station both recognize the sled; if not, control the quick disengagement station to quickly disengage the sled to the rear connection station at the first travel speed.

[0013] A further solution is that the step of determining whether the effective work station is operating normally includes:

[0014] If not, the position information of each sled on the effective work station is identified through the first information; the sled is controlled to transfer from the fast entry station to the empty station corresponding to the effective work station at the second travel speed; wherein the empty station corresponding to the effective work station approaches the sled on the effective work station, and the distance between each sled is maintained to be no less than a preset safety distance; the first information includes feedback signals from the front in-position detection switch and the rear in-position detection switch.

[0015] A further solution is that the step of determining whether the effective work station is operating normally includes:

[0016] If not, the position information of each sled on the effective working station is identified through the second information; it is determined whether each sled is between two stations or completely on the station. If the sled is between two stations, the sled at the front end of the faulty station is controlled to remain motionless; if the sled is completely on the station, the sled at the front end of the faulty station is controlled to move forward; the second information includes the feedback signals of the front in-position detection switch, the rear in-position detection switch and the middle detection switch.

[0017] A further solution is that after the step of determining whether the effective work station is operating normally, the step further includes:

[0018] If so, when the front in-position detection switch and the rear in-position detection switch on the first station corresponding to the effective working station fail to identify the sled, the control quickly enters the station and transfers the sled to the effective working station at the second travel speed.

[0019] A further solution is that after the step of controlling the quick disengagement station to quickly disengage the sled at the first travel speed to the rear end connection station, the method further includes:

[0020] The quick-disengagement station is controlled to receive the sled transferred from the effective working station at the second travel speed.

[0021] A further solution is that the identifying the position information of each sled at the effective working station by the first information; and controlling the sled to transfer from the fast-entry station to the empty station corresponding to the effective working station at the second travel speed specifically includes:

[0022] When the sled close to the empty station corresponding to the effective operation station is detected by the front in-position detection switch, the sled on the fast-entering station is controlled to be transferred to the empty station adjacent to the front in-position detection switch;

[0023] When the sled close to the empty station corresponding to the effective working station is detected only by the rear-arrival detection switch, the sled on the rapid entry station is controlled to be transferred to the empty station which is one empty station away from the rear-arrival detection switch.

[0024] A further solution is that the first travel speed is set to 20-30 m / min, and the second travel speed is set to 2-3 m / min.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a vehicle interior pre-installation production line control method, which significantly improves the production efficiency and safety of interior pre-installation through refined workstation layout and efficient automation control strategy. Specifically, by setting a vehicle receiving and waiting transfer machine, a quick entry station, an effective operation station, a quick separation station and a rear-end connection station, the slide can run continuously on the roller bed, and at the same time, the distance between the slides can be guaranteed to meet the safety distance, thereby improving the efficiency of interior pre-installation and ensuring the safety of the interior pre-installation process; the position information of the slide running on the roller bed can be accurately detected through the cooperation of the front in-position detection switch, the rear in-position detection switch and the middle detection switch; avoiding the misidentification of the slide position information caused by only using the front in-position detection switch and the rear in-position detection switch; thereby facilitating the timely transfer of the slide at the front end of the faulty station to other production lines when the effective operation station does not operate normally; effectively alleviating the pressure on the production line and reducing the production interruption time; the middle detection switch also facilitates the safe transfer of the slide from the vehicle receiving and waiting transfer machine to the quick entry station; more importantly, the setting of the middle detection switch enables the control system to more directly and quickly identify the position information of the slide, which is conducive to reducing the amount of program analysis, so as to avoid the program inferring the position information of the slide through complex algorithms and a large amount of data, thereby improving the operation efficiency of the system.

[0033] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] See also Figure 1 The present invention provides a vehicle interior pre-installation production line control method, which specifically includes the following steps:

[0036] Step S1, constructing a vehicle interior pre-installation production line; wherein the vehicle interior pre-installation production line comprises in sequence: a vehicle receiving waiting transfer machine, a quick entry station, an effective operation station, a quick separation station and a rear-end connection station; wherein the quick entry station, the effective operation station, the quick separation station and the rear-end connection station are all provided with a front in-position detection switch and a rear in-position detection switch, and an intermediate detection switch is also provided between them;

[0037] Specifically, the vehicle interior pre-installation production line includes: a vehicle receiving and waiting transfer machine, a fast entry station, an effective operation station, a fast exit station and a rear-end connection station. Among them, the fast entry station, the effective operation station and the fast exit station constitute the main production and transportation line. The fast entry station is the P01 station, the fast exit station is the P0N station, and the effective operation station is between the fast entry station and the fast exit station.

[0038] In this embodiment, the production conveying main line has a total of 8 stations, as follows Figure 2 and Figure 3 As shown, the quick entry station is P01, the quick exit station is P08, and the effective operation stations are P01-P07. The quick entry station, effective operation station, quick exit station and rear connection station all use roller beds, and a single roller bed uses multiple groups of rollers to form an independent conveying unit.

[0039] During the production and transportation process, the vehicle is fixed on the sled 4, and the sled 4 passes through the fast entry station, the effective operation station, the fast separation station and the rear connection station in sequence under the action of the roller. The fast entry station is used to quickly receive the sled 4 waiting for the vehicle to come out of the moving machine at a first travel speed, the fast separation station is used to quickly separate the sled 4 from the rear connection station at a first travel speed, and the effective operation station is used to slowly transfer the sled 4 at a second travel speed; since the travel speed of the sled 4 at the effective operation station is slow, workers can directly pre-install the interior without stopping the line. Since there is no need to stop the line for waiting, the line stop time can be reduced, continuous production operations can be achieved, and production efficiency can be improved.

[0040] It should be noted that when the sled 4 is transferred from the previous station to the next station, the roller beds corresponding to the two stations need to move and keep synchronous movement to prevent the sled 4 from slipping; therefore, the sled 4 that comes out of the waiting moving machine at the first travel speed is quickly entered into the station, and then the sled 4 is transferred to the effective working station at the second travel speed. Since the sled 4 that comes out of the waiting moving machine is quickly entered into the station, and then transferred to the effective working station at the second travel speed, the waiting moving machine has time to go to the storage area after the vehicle painting process to pick up the vehicle, thereby facilitating the continuous operation of the vehicle interior pre-installation.

[0041] In addition, the present application not only sets a front in-position detection switch 1 and a rear in-position detection switch 2 on a single roller bed, but also sets an intermediate detection switch 3 between roller beds. The front in-position detection switch 1, the rear in-position detection switch 2 and the intermediate detection switch 3 are all used to identify the sled 4. The front in-position detection switch 1, the rear in-position detection switch 2 and the intermediate detection switch 3 cooperate with each other to accurately identify the accurate position information of the sled 4 running on the roller bed; when the front in-position detection switch 1 detects the front end of the sled 4, and the rear in-position detection switch 2 of the station detects the rear end of the sled 4, when the intermediate detection switch 3 does not detect the sled 4, it indicates that the sled 4 is completely on the station, so that the accurate position information of the sled 4 can be obtained.

[0042] It should be noted that the roller beds corresponding to each workstation in the present application are independently controlled. The roller beds at each workstation are not driven by one motor to move simultaneously. The roller beds corresponding to each workstation are independently controlled based on the front in-position detection switch 1, the rear in-position detection switch 2 and the middle detection switch 3.

[0043] It should be noted that, since the present application is a continuous production operation, when the sled 4 moves to two adjacent effective working stations, for example, one sled 4 moves to the P04 and P05 stations, and the other sled 4 moves to the P05 and P06 stations, at this time, the front in-position detection switch 1 and the rear in-position detection switch 2 on the P05 station can both identify the sled 4; but in fact, the sled 4 is not completely at the P05 station. At this time, the middle detection switch 3 can be used to identify whether the sled 4 is completely at the station or between the two stations, thereby avoiding the misidentification of the position information of the sled 4 caused by only the front in-position detection switch 1 and the rear in-position detection switch 2.

[0044] Furthermore, the main production and conveying line of the present application is a prohibited entry zone for unauthorized personnel, and gates are set at both ends of the main production and conveying line. The gates are interlocked with the main production and conveying line. For the gates close to the quick-entry workstations on the main production and conveying line, they are automatically opened before the vehicle enters and automatically closed after the vehicle enters, prohibiting personnel from entering and exiting at will, thereby improving the safety of the line.

[0045] Finally, the roller bed of the present application adopts frequency conversion control. Although the travel speeds of the roller beds corresponding to the effective working stations remain consistent, so that the spacing between the slides 4 is kept within a safe distance range, which is convenient for the staff to perform safe operations between the slides 4, the travel speed of the effective working station can be adjusted according to the production rhythm requirements to adapt to the production rhythm.

[0046] Step S2, determining whether the front in-position detection switch and the rear in-position detection switch on the fast entry station recognize the slide, and whether the intermediate detection switch between the fast entry station and the effective operation station recognizes the slide; if not, controlling the fast entry station to receive the slide on the waiting moving machine at the first travel speed;

[0047] Specifically, when the front in-position detection switch 1 and the rear in-position detection switch 2 on the fast-entry station do not recognize the sled 4, and the intermediate detection switch 3 between the fast-entry station and the effective operation station does not recognize the sled 4, it indicates that there is no sled 4 at the fast-entry station, and the end of the sled 4 is not placed on the front end of the fast-entry station; at this time, it is safe to quickly transfer the sled 4 to the fast-entry station, and the fast-entry station can quickly receive the sled 4 on the waiting moving machine at the first travel speed, so that the front end of the sled 4 reaches the front in-position detection switch 1, and the rear end of the sled 4 reaches the rear in-position detection switch 2. In this embodiment, the first travel speed is set to 20-30m / min.

[0048] Step S3, determine whether the effective operation station is operating normally; if so, execute step S4; if not, execute step S6;

[0049] Specifically, when all stations corresponding to the effective working stations are running at the second travel speed, it indicates that the effective working stations are running normally, and none of the effective working stations has any faults. At this time, the sled 4 can be transferred from the latter station to the former station in sequence, and finally transferred to the last station corresponding to the effective working station. As mentioned above, this embodiment includes 8 stations P01-P08, of which P01 is a fast entry station, and P02-P07 are effective working stations. When P02-P07 stations are running at the second travel speed, it indicates that the effective working stations are running normally.

[0050] It should be noted that the front end of the production conveying main line is the end close to the rear-end connecting station, and the rear end of the production conveying main line is the end close to the quick entry station; therefore, the station after the effective working station refers to the station close to the quick entry station, and the station before the effective working station refers to the station close to the rear-end connecting station.

[0051] Step S4, when the front arrival detection switch on the first station corresponding to the effective working station recognizes the slide, the slide is controlled to enter the station quickly at the second travel speed and transferred to the effective working station, and then transferred to the quick exit station after passing through each station corresponding to the effective working station in turn;

[0052] As mentioned above, the first workstation corresponding to the effective working workstation is the P02 workstation. When the front in-position detection switch 1 of the P02 workstation detects the sled 4, the sled 4 is transferred to the workstation at the second travel speed through the control unit. This ensures that after the front in-position detection switch 1 of the previous workstation of the subsequent effective working workstation detects the sled 4, the front in-position detection switch 1 of the next workstation of the effective working workstation also detects the sled 4, so that the sleds 4 are kept at a preset safety distance from each other during the continuous production process. In this embodiment, the preset safety distance is set to 80 cm, and the second travel speed is set to 2-3 m / min.

[0053] It should be noted that when the front in-position detection switch 1 and the rear in-position detection switch 2 on the first station corresponding to the effective operation station do not recognize the slide 4, the rapid entry station is also controlled to transfer the slide 4 to the effective operation station at the second travel speed, and the distance between the slides 4 is greater than the preset safety distance. For example, when there are no vehicles waiting for the transfer vehicle to transfer in the storage area after the automobile painting process for a short period of time, the distance between the slides 4 will be greater than the preset safety distance.

[0054] Step S5, determining whether the front in-position detection switch and the rear in-position detection switch on the rear connection station both recognize the sled; if not, controlling the quick detachment station to quickly detach the sled to the rear connection station at the first travel speed;

[0055] Specifically, when the sled 4 is transferred to the quick-detachment station, that is, the quick-detachment station is full, and the front in-position detection switch 1 and the rear in-position detection switch 2 on the rear-end connection station do not recognize the sled 4, that is, the rear-end connection station is vacant; at this time, the vehicle is allowed to leave, and the gate at the front end of the production conveyor line is controlled to open, and the sled 4 on the quick-detachment station drives the vehicle to quickly detach from the rear-end connection station. When the rear-end connection station is full, the gate is closed again.

[0056] It should be noted that the sled 4 is transferred from the last station corresponding to the effective working station to the quick disengagement station at the second travel speed, while the sled 4 is transferred from the quick disengagement station to the rear-end connection station at the first travel speed; in the process of the sled 4 on the quick disengagement station being transferred to the rear-end connection station, the sled 4 on the effective working station is being transferred to the quick disengagement station at the second travel speed; since the first travel speed is greater than the second travel speed, after the sled 4 on the quick disengagement station is disengaged, the front end of the sled 4 on the effective working station has not yet reached the quick disengagement station; at this time, the quick disengagement station is ready to receive the sled 4 transferred from the effective working station at the second travel speed.

[0057] Step S6, identifying the position information of each sled on the effective working station through the first information; controlling the sled to transfer from the fast-entry station to the empty station corresponding to the effective working station at the second travel speed; wherein the empty station corresponding to the effective working station approaches the sled on the effective working station, and the distance between each sled is kept not less than a preset safety distance; the first information includes the feedback signals of the front in-position detection switch and the rear in-position detection switch;

[0058] Specifically, when fault information of the workstation corresponding to the effective workstation or the quick-disconnect workstation or the rear-end connection workstation is received, the front end of the production conveyor line will be blocked, and the effective workstation cannot operate normally. Sometimes the waiting transfer vehicle cannot always receive the vehicle from the storage area after the automobile painting process, and the effective workstation will be empty at this time; when an effective workstation is empty, that is, the front in-position detection switch 1 and the rear in-position detection switch 2 on the workstation corresponding to the effective workstation have not recognized the sled 4, and the waiting transfer vehicle receives the vehicle from the storage area after the automobile painting process, the vehicle will be normally transferred to the quick-entry workstation, and the system will identify the position information of each sled 4 on the effective workstation, so as to determine the empty workstation corresponding to the effective workstation to which the sled 4 on the quick-entry workstation is to be transferred, and the empty workstation is close to the sled 4 on the effective workstation, and the distance between each sled 4 is kept not less than the preset safety distance.

[0059] It should be noted that the key to determining the empty station corresponding to the effective working station to which the sled 4 on the quick entry station is to transfer is to determine the position information of the sled 4 close to the empty station; when the sled 4 close to the empty station is detected by the front in-place detection switch 1, the sled 4 on the quick entry station can be transferred to the empty station adjacent to the front in-place detection switch 1; when the sled 4 close to the empty station is only detected by the rear in-place detection switch 2, the sled 4 on the quick entry station cannot be transferred to the empty station adjacent to the rear in-place detection switch 2, so as to prevent the distance between the sleds 4 from being less than the preset safety distance; at this time, the sled 4 on the quick entry station should be transferred to the empty station separated from the rear in-place detection switch 2 by one empty station.

[0060] For example: when a line jam occurs at the front end of the production conveyor line, the front in-position detection switch 1 and the rear in-position detection switch 2 corresponding to the P04 station corresponding to the effective working station both detect the slide, and the P03 and P02 stations are empty stations. At this time, the slide 4 on the fast-entering station can be transferred to the P03 station at the second travel speed, and the two empty stations P03 and P02 are automatically filled in turn; when only the rear in-position detection switch 2 at the P04 station corresponding to the effective working station detects the slide, the P03 and P02 stations are empty stations. At this time, the slide 4 on the fast-entering station can be transferred to the P02 station at the second travel speed, and cannot be transferred to the P03 station.

[0061] Step S7, identifying the position information of each slide on the effective working station through the second information; judging whether each slide is between two stations or completely on the station, if the slide is between two stations; controlling the slide at the front end of the faulty station to remain motionless; if the slide is completely on the station, controlling the slide at the front end of the faulty station to move forward; wherein the second information includes the feedback signals of the front in-position detection switch, the rear in-position detection switch and the middle detection switch;

[0062] It should be noted that when the effective working station is not operating normally, it is also necessary to determine the position information of the sled 4 at the front end of the faulty station, so as to transfer the sled 4 at the front end of the faulty station to other production lines in time; and because the transfer of the sled 4 from the previous station to the next station requires the synchronous movement of the roller beds corresponding to the two adjacent stations; at this time, it is necessary to determine whether each sled 4 is between the two stations or completely on the station, and on this basis, not only the feedback signals of the front in-position detection switch 1 and the rear in-position detection switch 2 should be obtained, but also the feedback signal of the middle detection switch 3 should be obtained, so as to determine whether the sled 4 located at the front end of the faulty station can move forward, and then control the sled 4 located at the front end of the faulty station to remain stationary or control the sled 4 located at the front end of the faulty station to move forward.

[0063] For example: when each sled 4 is completely moved to the P02-P07 station, the P04 station fails; the front in-position detection switch 1 and the rear in-position detection switch 2 of each station can identify the sled 4, while the middle detection switch 3 cannot identify the sled 4. At this time, the sled 4 on the P05-P07 station can be controlled to move forward so as to be transferred to other production lines in time; and when each sled 4 is between two adjacent stations, for example, one of the sleds 4 has its two ends between the P02 station and the P03 station, and one sled 4 is between the P03 station and the P04 station; and so on, the other sleds 4 are between the P04 station and the P05 station and between the P05 station and the P06 station, as follows Figure 4 and Figure 5 As shown, when the P04 station fails, since the transfer of the slide 4 from the previous station to the next station requires the synchronous movement of the roller beds of the two adjacent stations, the slide 4 on the P05-P07 stations cannot be controlled to move forward. At this time, although the front in-position detection switch 1 and the rear in-position detection switch 2 of each station can identify the slide 4, the middle detection switch 3 can also identify the slide 4, thereby avoiding misjudgment that each slide 4 is completely on the station and avoiding malfunction of the corresponding roller bed.

[0064] Furthermore, if one sled 4 is between the P03 station and the P04 station, and one sled 4 is between the P04 station and the P05 station; and the sled 4 at the front end is completely on the P06 station and the P07 station. When the P04 station fails, the sleds 4 on the P04 station and the P05 station remain stationary, while the sleds 4 on the P06 station and the P07 station can move forward; that is, when the sled 4 at the front end station is not affected by the failed station, the roller bed corresponding to the front end station does not need to move at the same time as the roller bed of the failed station, and the sled 4 on it can move forward normally.

[0065] In summary, the present invention provides a vehicle interior pre-installation production line control method, which significantly improves the production efficiency and safety of interior pre-installation through refined workstation layout and efficient automation control strategy. Specifically, by setting a vehicle receiving and waiting moving machine, a quick entry station, an effective operation station, a quick separation station and a rear-end connection station, the sled can run continuously on the roller bed, and at the same time, it can ensure that the distance between the sleds 4 meets the safety distance, thereby improving the efficiency of interior pre-installation and ensuring the safety of the interior pre-installation process; the position information of the sled 4 running on the roller bed can be accurately detected through the mutual cooperation of the front in-position detection switch 1, the rear in-position detection switch 2 and the middle detection switch 3; avoiding the misidentification of the position information of the sled 4 only by the front in-position detection switch 1 and the rear in-position detection switch 2; thereby facilitating the timely transfer of the sled at the front end of the faulty station to other production lines when the effective operation station does not operate normally; effectively relieving the pressure on the production line and reducing the production interruption time; the middle detection switch 3 also facilitates the safe transfer of the sled 4 from the vehicle receiving and waiting moving machine to the quick entry station; more importantly, the setting of the middle detection switch 3 enables the control system to more directly and quickly identify the position information of the sled, which is conducive to reducing the amount of program analysis, so as to avoid the program inferring the position information of the sled 4 through complex algorithms and a large amount of data, thereby improving the operation efficiency of the system.
