Description

Technical Field

[0001] The present invention relates to a parallel cell-based mobility production system.

Background Art

[0002] The present invention relates to a vehicle production method for future compatibility. Conventionally, a consistent mass production method centered around a conveyor has been maintained, but in the future society, the industry is evolving mainly around electric vehicles, and in order to meet the needs of customers who emphasize diversity, it is expected that a change to a customer-centered manufacturing method will be necessary.

[0003] Conventionally, vehicles are introduced in a consistent sequence, and production is carried out in a consistent sequence until the completed vehicle is finished. The working hours for all processes are the same, and vehicles with parts that exceed the working hours are difficult to introduce or production volume constraints occur. That is, it is judged that there are difficulties in meeting the diverse customer needs of future society in a situation where vehicle production must be carried out while maintaining the production structure unique to mass production of a consistent small variety.

[0004] Therefore, it is necessary to innovate a manufacturing method that can easily and quickly produce a variety of vehicles at one point, breaking away from such traditional vehicle production methods.

Modes for Carrying Out the Invention

[0014] FIG. 1 is a configuration diagram of a parallel cell-based mobility production system according to an embodiment of the present invention, FIG. 2 is a diagram showing a manual cell of a parallel cell-based mobility production system according to an embodiment of the present invention, FIG. 3 is a diagram showing an automatic cell of a parallel cell-based mobility production system according to an embodiment of the present invention, and FIG. 4 is a diagram showing an operation method of a parallel cell-based mobility production system according to an embodiment of the present invention.

[0015] FIG. 1 shows the configuration of a parallel cell-based mobility production system according to an embodiment of the present invention. The parallel cell-based mobility production system according to the present invention is a parallel cell-based mobility production system that enables the production of various vehicle types through a single production system. It is composed of one or more cells arranged in series, and a front serial production line (100) where vehicles of various types sequentially pass through and production operations are performed. A plurality of cells arranged in a matrix form are provided, and by being input into the selected cells as the vehicle moves from the front to the rear, a parallel production line (300) is configured with various combinations of sub-lines matched by vehicle type, and a rear serial production line (500) into which vehicles of various types that have passed through the parallel production line are sequentially input.

[0016] The production process of vehicles is very complex and sequential. In the case of the present invention, this is simplified into a front serial production line (100), a parallel production line (300), and a rear serial production line (500). And the front serial production line (100) is composed of processes where the change in work is not significant even if the vehicle type is different by integrating a series of common production processes.

[0017] And the parallel production line (300) is composed of variable cells (310) where each cell can selectively perform various operations.

[0018] Finally, the rear serial production line (500) is a line into which vehicles of various types that have passed through the parallel production line are sequentially input, and sequential common operations are performed. And finally, it passes through the inspection line (700) to perform various inspections and tests.

[0019] Specifically, the parallel cell-based mobility production system of the present invention enables the production of vehicles of various types in one place. When there are various vehicle types, there are differences in the mounting order for each vehicle type, and even for the same type of work, there are differences in the amount of work. Also, the differences in optional parts between vehicles are large, and customers place special orders separately, so it is difficult to handle with the conventional conveyor production system.

[0020] Therefore, in the present invention, a parallel cell-based mobility production system is proposed that enables the production of a variety of vehicle types through a single production system. First, the front serial production line (100) is composed of one or more cells arranged in series, and vehicles of various vehicle types pass through sequentially, and production operations are performed.

[0021] And in the parallel production line (300), a plurality of cells (310) arranged in a matrix form are provided. As the vehicle is moved from the front to the rear and is input into the selected cell, a variety of combinations of sub-lines matched by vehicle type are configured. In the case of the embodiment shown in FIG. 1, an example is shown in which a total of 16 types of sub-lines are combined by a combination of a matrix of two rows and four columns.

[0022] And in the rear serial production line (500), vehicles of various vehicle types that have passed through the parallel production line (300) are sequentially input.

[0023] First, the front serial production line (100) performs pre-work and chassis installation processes. Specifically, the front serial production line (100) is composed of a plurality of cells arranged in series, and each cell sequentially performs pre-work and chassis installation processes.

[0024] The front serial production line (100) is composed of a pre-work cell (110), a roof installation cell (120), indoor and outdoor trim work cells (130, 140, 150), a chassis alignment work cell (160), a drive module installation cell (170), and a chassis mounting cell (180) arranged in sequence. Vehicles of various vehicle types pass through each cell sequentially and work is performed.

[0025] For example, in the case of the pre-work cell (110), the vehicle body is input, and pre-work processes are performed before chassis work. This is a manual cell that is manually operated, and operations such as sunroof, engine room work, and wire harness input are performed. In FIG. 1, it is displayed as T1 manual.

[0026] In the case of the roof installation cell (120), it is displayed as ROOF AUTO in Fig. 1, and a sunroof, roof rack, etc. are installed.

[0027] Also, the indoor and outdoor trim work cells (130, 140, 150) are composed of a first cell, a second cell, and a third cell arranged in sequence. The first cell (130) is displayed as T2 manual in Fig. 1, and one or more of the vehicle's wiring installation and seat belt installation are performed.

[0028] The indoor and outdoor trim work cells are composed of a first cell, a second cell, and a third cell arranged in sequence. The second cell (140) is displayed as TA1 in Fig. 1, and one or more of the crash pad installation and carpet loading are performed.

[0029] The indoor and outdoor trim work cells are composed of a first cell, a second cell, and a third cell arranged in sequence. The third cell (150) is displayed as TA2 in Fig. 1, and one or more of the headlining installation and washer fluid reservoir installation are performed.

[0030] The chassis alignment work cell (160) is displayed as C1 in Fig. 1, and alignment work such as brake tubes, EPCU, and pre-decking is performed.

[0031] The drive module installation (170) is displayed as CM in Fig. 1, and the PE module and high-voltage battery mounting are performed.

[0032] The chassis mounting cell (180) is displayed as C2 in Fig. 1, and a wheel speed sensor, wheel guard, brake hose, etc. are installed.

[0033] After such a series of processes are sequentially performed on all vehicles, they are put into the sub-lines corresponding to each vehicle type.

[0034] In particular, by arranging the chassis-mounted cell (180) on the front serial production line (100), the trim line can be continuously configured on the parallel production line (300), ensuring production flexibility.

[0035] The parallel production line (300) is composed of a plurality of cells (310), and a total of 16 types of sub-lines can be formed through various combinations of cells depending on the direction of progress. In each cell, various operations can be selectively carried out, specifically, one or more of indoor trim installation, console installation, air conditioning duct installation, and floor carpet installation can be carried out in various ways.

[0036] And below the parallel production line (300), a rear serial production line (500) is arranged, and an expansion area (320) is set between the parallel production line (300) and the rear serial production line (500).

[0037] The rear serial production line (500) arranges the option part mounting cell (510), wheel mounting cell (520), bumper mounting cell (530), and door mounting cell (540) in series.

[0038] The option part mounting cell (510) is shown as FA1 in Figure 1 and performs one or more of seat installation, glass installation, and FEM installation.

[0039] The wheel mounting cell (520) is shown as FA2 in Figure 1 and performs one or more of wheel installation, tire installation, and under cover installation.

[0040] The bumper mounting cell (530) is shown as F manual in Figure 1 and performs one or more of bumper installation, pedal installation, wiper installation, and wire ring installation.

[0041] The door mounting cell (540) is shown as FA3 in Figure 1, and doors and weather strips are installed.

[0042] Then, the vehicles produced from the rear in-line production line (500) are successively fed into the inspection line (700) and undergo various inspections and tests.

[0043] On the other hand, as shown in FIG. 1, a parallel production line (300) and a rear in-line production line (500) are provided on the side of the front in-line production line (100). And the rear in-line production line (500) is arranged below the parallel production line (300). However, an expansion area (320) is set between the parallel production line (300) and the rear in-line production line (500).

[0044] FIG. 4 is a diagram showing an operation method of a parallel cell-based mobility production system according to an embodiment of the present invention. In the case of FIG. 4, a sub-line is additionally formed by adding a parallel production line through a new cell (310') in the expansion area (320). Through these new routes, a sub-line can be additionally installed during the production of vehicles with a large amount of work in the interior or engine room, and production can be carried out through the additional route with the fastest production flow.

[0045] Or, for production increase, after adding the maximum number of personnel to the manual process, if there is difficulty in increasing the production volume due to delays in the automatic process, it is possible to increase the automatic line and add an additional sub-line.

[0046] On the other hand, these cells are divided into manual cells where manual work is performed and automatic cells where robots perform automatic assembly. FIG. 2 shows an example of a manual cell, and FIG. 3 shows an example of an automatic cell.

[0047] And each cell can be easily moved within the factory. By efficiently repositioning the cells, the production efficiency is improved. When maintenance or replacement of a specific sub-line is required, an extra sub-line can be added for maintenance, and there is an advantage that production can be continuously carried out without interruption.

[0048] According to the parallel cell-based mobility production system of the present invention, during vehicle production, it is possible to absorb the diversity of customer needs through the production of multiple vehicle models. Even when an abnormality occurs during the process, production can continue, and the production volume can be increased without shutdown and separate construction. Since the operation of each cell can be set individually, flexibility is ensured, and rapid changes in production facilities due to early product cycle changes are possible. It can be installed and operated not only in a factory located in the suburbs but also in a factory inside a building in the city center.

[0049] As described above, the present invention has been described with reference to the drawings in relation to specific embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be variously improved and changed within the scope not departing from the technical idea of the present invention.
