[0047] In an embodiment of the present invention, the positioners (30) are configured to position a part transfer pallet (50), which will be further described later, at a set position on the station frame (10).

[0048] In one example, four positioners (30) are provided, and each positioner (30) is mounted on a corresponding mounting part (17) of a corresponding base frame (11) in a station frame (10).

[0049] FIG. 2 is a drawing illustrating a positioner applied to a component assembly system of an automated line according to a first embodiment of the present invention.

[0050] Referring to FIGS. 1 and 2, each positioner (30) according to an embodiment of the present invention includes a positioning body (31) mounted on a corresponding mounting part (17) of a corresponding base frame (11).

[0051] The positioning body (31) may be formed in a cylindrical shape. For example, the positioning body (31) may be joined to the mounting part (17) in various ways well known to those skilled in the art, such as bonding or bolting.

[0052] This positioning body (31) includes a pin guide groove (33) formed on the upper surface and a pin coupling hole (35) connected to the pin guide groove (33).

[0053] Here, the pin guide groove (33) may be formed in a tapered shape in which the cross-sectional diameter gradually decreases from the top to the bottom. And, the pin coupling hole (35) is connected to the bottom of the pin guide groove (33).

[0054] Referring to FIG. 1, the part transfer pallet (50) according to an embodiment of the present invention supports a part (1) and is configured to transfer the part (1) to a set position on a station frame (10).

[0055] Furthermore, the above-mentioned part transfer pallet (50) is configured to be movable by being picked up by a movable trolley (70), which will be further described later.

[0056] This part transfer pallet (50) includes a pallet body (51), at least one leg (53), at least one positioning pin (55), and at least one part alignment unit (57).

[0057] The above pallet body (51) is provided in the form of a square plate, for example. The above pallet body (51) includes an upper surface that supports a part (1) and a lower surface opposite to the upper surface.

[0058] The pallet body (51) includes at least one bogie connection hole (52). In one example, a pair of bogie connection holes (52) may be formed along a diagonal direction on the inner edge of the pallet body (51).

[0059] At least one leg (53) is connected to the lower edge portion of the pallet body (51) and extends downward. The positioning pin (55) is configured to position the part transfer pallet (50) correctly at a set position on the station frame (10).

[0060] Each positioning pin (55) is mounted at the bottom of each leg (53) and extends downward, and is coupled to the corresponding positioner (30).

[0061] As shown in FIG. 3, the positioning pin (55) includes a tapered portion (56) formed at the lower end of the positioning pin (55). The tapered portion (56) may be formed in a tapered shape such that the cross-sectional diameter gradually decreases from the upper side to the lower side.

[0062] The above tapered portion (56) is coupled to the pin coupling hole (35) of the positioner (30). Here, the tapered portion (56) can be coupled to the pin coupling hole (35) while being guided to the pin coupling hole (35) by the pin guide groove (33) of the positioner (30).

[0063] The above-mentioned part alignment units (57) are configured to align and position the part (1) at a set position on the upper surface of the pallet body (51). In one example, the above-mentioned part alignment units (57) are each installed at the corner portions of the upper surface of the pallet body (51). In another example, the above-mentioned part alignment units (57) are arranged diagonally on the upper surface of the pallet body (51).

[0064] The installation position of these parts alignment units (57) can be varied on the upper surface of the pallet body (51) depending on the type of part (1). For example, the parts alignment units (57) may be movable in a set direction on the upper surface of the pallet body (51), or a plurality of installation positions may be predetermined on the upper surface of the pallet body (51) according to the type of various parts (1), and the parts alignment units (57) may be selectively installed in at least one of the plurality of installation positions.

[0065] Referring to FIG. 1, the movable cart (70) according to an embodiment of the present invention is configured to move on the floor (5) of a process workshop and transport a parts transport pallet (50) to a set position.

[0066] The above-mentioned mobile cart (70) may include an autonomous mobile robot (hereinafter referred to as 'AMR') (71) capable of autonomously driving along a set path on the floor (5) of the process workshop.

[0067] FIG. 4 is a drawing illustrating a movable trolley applied to a parts assembly system of an automated line according to the first embodiment of the present invention.

[0068] Referring to FIGS. 1 and FIGS. 4, the AMR (71) according to an embodiment of the present invention includes a lifter (73) that is movable in the up and down direction. The lifter (73) may be provided in the form of a square block.

[0069] This lifter (73) can be moved up and down by a bogie drive device well known to those skilled in the art. And, at least one lift pad (75) is installed on the corner portion of the upper surface of the lifter (73).

[0070] Furthermore, a pair of lift pads (75) arranged diagonally from one of the lift pads (75) may have a lift pin (77) installed along the vertical direction. The upper portion of the lift pin (77) may be provided in a tapered shape.

[0071] Here, the lift pad (75) supports the lower surface of the pallet body (51). And, the lift pin (77) can be coupled to the trolley coupling hole (52) of the pallet body (51).

[0072] As the lifter (73) moves upward, the lift pin (77) is coupled to the trolley coupling hole (52) of the pallet body (51), and the lifter (73) can move the parts transfer pallet (50) upward. Additionally, as the lifter (73) moves downward, the parts transfer pallet (50) can be moved downward.

[0073] Alternatively, the movable cart (70) according to an embodiment of the present invention is not limited to including an AMR (71) as described above, but may include an AGV () or a manual cart known to those skilled in the art.

[0074] Hereinafter, the operation of the component assembly system (100) of the automation line according to the first embodiment of the present invention configured as above will be described in detail with reference to FIGS. 1 to 4.

[0075] First, the AMR (71) and the parts transfer pallet (50) are each located in a designated area of ​​the floor (5) of the process workshop. At this time, the lifter (73) of the AMR (71) can be located at least below the pallet body (51).

[0076] A part loading device (not shown in the drawing) grips a part (1), such as an electric vehicle battery (3), loaded at a set loading location and transports it to the set area, and loads the part (1) onto the upper surface of the pallet body (51) of the part transport pallet (50).

[0077] Then, at least one part alignment unit (57) of the part transfer pallet (50) aligns the part (1) at a set position on the upper surface of the pallet body (51). At this time, the part alignment unit (57) can align the part (1) by automatically or manually varying its position according to the model of the part (1).

[0078] With the above-mentioned part (1) aligned on the pallet body (51), the AMR (71) autonomously drives along a set path on the floor (5) of the process workshop and moves to the lower side of the pallet body (51).

[0079] Then, the AMR (71) moves the lifter (73) upward from a set position on the lower side of the pallet body (51).

[0080] Accordingly, the lifter (73) supports the lower surface of the pallet body (51) through at least one lift pad (75) and lifts the parts transfer pallet (50) upward. At this time, the lifter (73) can lift the parts transfer pallet (50) upward by being connected to the trolley coupling hole (52) of the pallet body (51) through the lift pin (77).

[0081] Next, the AMR (71) autonomously drives along a newly set path and transports the parts transport pallet (50) to a set position on the station frame (10). In this state, the AMR (71) moves the lifter (73) downward to move the parts transport pallet (50) downward.

[0082] As the part transfer pallet (50) moves downward, the tapered portion (56) of at least one positioning pin (55) is coupled to the pin coupling hole (35) of the corresponding positioner (30). Here, if a transfer deviation of the part transfer pallet (50) occurs (i.e., the difference between the target position and the actual position of the part transfer pallet (50)), the tapered portion (56) is guided to the pin coupling hole (35) by the pin guide groove (33) of the positioner (30) and coupled to the pin coupling hole (35).

[0083] Accordingly, the positioner (30) can position the part transfer pallet (50) at a set position on the station frame (10) by combining with the positioning pin (55).

[0084] As described above, when the part transfer pallet (50) is positioned correctly on the station frame (10), the sealer application device (8) of the part assembly tool (7) applies sealer from the station frame (10) to the part (1) on the part transfer pallet (50).

[0085] Here, the sealer application device (8) can apply the sealer while moving in the forward, backward, left, right, and up and down directions by means of the driving device (9) on the station frame (10).

[0086] The parts assembly system (100) of the automation line according to the first embodiment of the present invention as described so far can arrange parts (1) of various types on a parts transfer pallet (50).

[0087] In addition, the parts assembly system (100) of the above-mentioned automation line can transfer parts transfer pallets (50) to the station frame (10) by means of a movable trolley (70) such as an AMR (71).

[0088] And, the parts assembly system (100) of the above-mentioned automation line can position the parts transfer pallet (50) at a set position on the station frame (10) through the positioner (30) and the positioning pin (55).

[0089] Thus, the parts assembly system (100) of the automation line according to the first embodiment of the present invention can transport parts (1) of various types to a station frame (10) without using a conveyor, and assemble the parts (1) on the station frame (10).

[0090] Accordingly, the parts assembly system (100) of the automated line according to the first embodiment of the present invention can secure logistics flexibility and production flexibility for multiple types of parts (1) and reduce equipment investment costs.

[0091] FIG. 5 is a drawing illustrating a modified example of a station frame applied to a component assembly system of an automated line according to the first embodiment of the present invention.

[0092] Referring to FIG. 5, in the component assembly system (100) of the automation line according to an embodiment of the present invention, the station frame (10) may further include at least one reinforcing frame (18).

[0093] Each reinforcing frame (18) is intended to connect at least two base frames (11) of the station frame (10) to each other. Each reinforcing frame (18) is positioned between the base frames (11) facing each other. The reinforcing frame (18) can be connected to the base frames (11) facing each other through connecting portions (19) at both ends thereof.

[0094] As described above, by connecting the base frames (11) to the reinforcing frame (18), the reinforcing frame (18) can prevent positional dispersion of the positioners (30) due to twisting of the station frame (10) during transportation of the station frame (10).

[0095] Accordingly, the component assembly system (100) of the automated line according to an embodiment of the present invention can secure a position alignment diagram of a component transfer pallet (50: see FIG. 1) with respect to a station frame (10) during the component assembly process.
