FIG.

For clarity of explanation, the following description and drawings have been omitted and simplified as appropriate. Note that in each drawing, the same elements are given the same reference numerals, and duplicate explanations have been omitted as necessary.

First embodiment
First, the component installation device according to the first embodiment is used in the manufacture of a secondary battery. In the following description, a component installation device that installs a cap that prevents dust from entering during welding in the assembly of a secondary battery will be described. Note that the component to be installed by the component installation device can be any component that requires positioning accuracy and can be held by suction. In order to explain the component to be installed by the component installation device according to the first embodiment, the configuration of a secondary battery will be described first. Note that the component installation device 30 described below will be described as an example in which the cap 21 is installed by inserting it downward, but the insertion direction of the cap 21 is not particularly limited.

1 shows a schematic diagram of a secondary battery according to the first embodiment. As shown in FIG. 1, the secondary battery 1 according to the first embodiment has a case 10 and a lid 11. The case 10 houses an electric power unit. The lid 11 seals the case 10 when the electric power unit is housed in the case 10. The lid 11 is provided with a negative terminal 12 and a positive terminal 13. The negative terminal 12 is an electrode that extracts electric power from the negative electrode of the electric power unit in the case 10, and is joined to a negative electrode post that penetrates the lid 11 by a negative electrode crimping tool 12a. The negative electrode post, the negative electrode crimping tool 12a, and the negative electrode terminal 12 are joined by laser welding. The positive electrode terminal 13 is an electrode that extracts electric power from the positive electrode of the electric power unit in the case 10, and is joined to a positive electrode post that penetrates the lid 11 by a positive electrode crimping tool 13a. The positive electrode post, positive electrode crimping tool 13a, and positive electrode terminal 13 are joined by laser welding.

The lid 11 is also provided with a release valve 14 and a liquid injection hole 15. The release valve 14 is a valve that reduces the internal pressure of the sealed case 10 when the internal pressure inside the case 10 exceeds a certain level. The liquid injection hole 15 is a hole provided for injecting electrolyte into the case 10, and is sealed with a sealing member 22 after the electrolyte is injected. However, since the electrolyte is injected into the case 10 after the lid 11 is welded to the case 10, if nothing is done when the lid 11 is welded to the case 10, there is a risk that dust will enter the case 10 through the liquid injection hole 15. Therefore, in the manufacturing process of the secondary battery, a cap 21 is fitted into the liquid injection hole 15 when the lid 11 is welded to the case 10 to prevent dust from entering the case 10 through the liquid injection hole 15.

Here, FIG. 2 shows a flowchart of the assembly process of the secondary battery according to the first embodiment. As shown in FIG. 2, in the assembly of the secondary battery, first, a current collector is welded to the electrode body, and the current collector is welded to the electrode penetrating the lid 11, and the opening of the case 10 is closed with the lid 11 while the electrode body is stored in the case 10 (step S1). Next, a cap 21 is inserted into the liquid injection hole 15 of the lid 11 (step S2). Next, the case 10 and the lid 11 are welded (step S3). Next, the cap 21 is removed from the liquid injection hole 15, and the electrolyte is injected into the case 10 through the liquid injection hole 15 (step S4). Next, the lid 11 and the liquid injection hole 15 are welded with the sealing member 22 placed on the liquid injection hole 15, thereby sealing the liquid injection hole 15 with the sealing member 22 (step S5). This completes the assembly process of the secondary battery. In this process, the component assembly device according to the first embodiment is used in the process of inserting the cap 21 into the liquid injection hole 15 in step S2.

The part assembly device 30 according to the second embodiment will be described in detail. FIG. 3 is a diagram for explaining the structure of the part assembly device 30 according to the first embodiment. As shown in FIG. 3, the part assembly device 30 according to the first embodiment has a holding unit 31, a guide unit 32, and a sliding control unit 33. FIG. 3 also shows a cap 21 as a part that is transported by the part assembly device 30, and a lid 11 to which the cap 21 is to be assembled.

The holding portion 31 has an adsorption surface at one end for adsorbing the cap 21. The holding portion 31 also has a first opening, a second opening, and an airflow control structure. The first opening is provided on the adsorption surface and applies an adsorption force to the component by airflow in the suction direction. The second opening is provided on the side of the holding portion 31 and draws in airflow in the suction direction. The airflow control structure will be described in detail later.

The guide part 32 grips the side of the holding part 31 that is perpendicular to the suction surface so that the holding part 31 can slide in a direction perpendicular to the suction surface. The guide part 32 moves from the location where the cap 21 is prepared to the location of the liquid injection hole 15 by a guide part moving means such as a robot arm (not shown).

The sliding control unit 33 slides the holding unit 31 between a first state in which the suction surface is recessed below the end of the guide unit 32 in the sliding direction of the holding unit 31, and a second state in which the suction surface protrudes beyond the end of the guide unit 32. In FIG. 3, the upper diagram shows the configuration when the part installation device 30 is in the first state, and the lower diagram shows the configuration when the part installation device 30 is in the second state.

Here, the airflow control structure of the component assembly device 30 according to the first embodiment will be described in detail. The airflow control structure is configured so that the suction force applied to the component by the first opening is smaller in the second state than in the first state, and the airflow sucked in from the second opening is larger in the second state than in the first state.

Specifically, the part assembly device 30 according to the first embodiment has a main path P11 and a sub-path P12 as an airflow control structure. The main path P11 communicates with the first opening and allows airflow in the suction direction. The sub-path P12 communicates the main path P11 with the second opening. The second opening is provided at a position that is covered by the guide portion 32 in the first state and exposed in the second state. In addition, it is preferable that the cross-sectional area of the main path P11 is provided to be larger than the cross-sectional area of the sub-path P12. By making the cross-sectional area of the main path P11 larger than the cross-sectional area of the sub-path P12, the part assembly device 30 can maintain the suction force of the cap 21 while weakening the suction force of the suction surface when in the second state compared to the first state.

As shown in FIG. 3, in the component assembly device 30 according to the first embodiment, in the first state in which the cap 21 is attached to the suction surface of the holding unit 31 with a strong suction force, the guide unit 32 becomes a wall that covers the periphery of the suction surface, preventing the cap 21 from shifting sideways on the suction surface. In addition, in the first state, the gap between the guide unit 32 and the cap 21 is set to be small. In this way, by setting the area of the suction surface of the holding unit 31 and the area and shape of the suction portion of the cap 21 to be approximately the same, the positional accuracy of the cap 21 relative to the holding unit 31 can be improved. In addition, in the first state, the second opening of the sub-path P12 is blocked by the guide unit 32, and a strong suction force is generated at the first opening.

Referring to the second state in FIG. 3, in the component assembly device 30 according to the first embodiment, the suction surface of the holding portion 31 protrudes beyond the end of the guide portion 32, and the second opening is exposed. Therefore, most of the airflow in the suction direction of the main path P11 is supplied via the sub-path P12. In the second state, the component assembly device 30 uses the airflow flowing through the sub-path P12 to collect dust around the assembly position of the cap 21 and discharge it to the outside. This dust may include sliding dust from the component assembly device 30, dust from the cell clamp jig, dust related to the cap, etc.

In the second state of FIG. 3, the airflow sucked in from the first opening is less than in the first state, and therefore the suction force acting on the suction surface of the holding part 31 is less than in the first state. In the second state, the suction surface of the holding part 31 protrudes beyond the end of the guide part 32. As a result, in the component assembly device 30 according to the first embodiment, there is no wall around the holding part 31 in the second state, and therefore the cap 21 is able to slide sideways on the suction surface. This sliding will be described with reference to FIG. 4.

Figure 4 shows a diagram for explaining the lateral slippage effect of the component assembly device 30 according to the first embodiment. In order to explain the lateral slippage effect, Figure 4 shows a component assembly device 300 as a comparative example in which a side wall that prevents the cap 21 from slipping is fixedly provided around the suction surface.

As shown in FIG. 4, the tip of the cap 21 is tapered. Therefore, if the central axis of the cap 21 deviates from the central axis of the liquid inlet 15 within the range of the taper width, the cap 21 is inserted into the liquid inlet 15 while shifting laterally along the taper. At this time, in the component assembly device 30, there is nothing around the suction surface of the holding part 31 that prevents the cap 21 from shifting laterally in the second state. Also, in the component assembly device 30 according to the first embodiment, the suction force that attracts the cap 21 to the suction surface of the holding part 31 in the second state is weaker than in the first state. Therefore, in the component assembly device 30 according to the second embodiment, the cap 21 shifts laterally smoothly, and the cap 21 is accurately inserted into the liquid inlet 15.

On the other hand, in the comparative example, the lateral displacement of the cap 21 is restricted by the side walls provided around the suction surface of the component assembly device 300. Therefore, when using the component assembly device 300 according to the comparative example, in order to accurately insert the cap 21 into the liquid injection hole 15, there is a problem in that two precisions must be highly controlled: the relative position precision (precision of aligning the central axes) between the component assembly device 300 and the cap 21, and the precision of aligning the central axes of the component assembly device 300 and the liquid injection hole 15.

As described above, in the component assembly device 30 according to the first embodiment, the lateral shift width of the cap 21 can be made large in the second state. Therefore, by using the component assembly device 30 according to the first embodiment, the accuracy of the alignment between the central axis of the cap 21 and the central axis of the liquid inlet 15 can be relaxed.

In addition, by relaxing the centering accuracy, the tolerances of the sizes of the cap 21 and the liquid inlet 15 can be made wider, reducing the cost of materials. Furthermore, by relaxing the centering accuracy, the adjustment time required to move the part assembly device 30 to the assembly position can be reduced, and the manufacturing cost of the part assembly device 30 can be reduced.

In addition, in the component assembly device 30 according to the first embodiment, there is no need to reduce the pressure of the suction airflow supplied to the main path P11 in order to attenuate the suction force in order to increase the lateral sliding of the cap 21 on the suction surface of the holding portion 31. As a result, the component assembly device 30 according to the first embodiment can shorten the component assembly cycle time. In addition, since there is no need to reduce the pressure of the suction flow, the configuration of the component assembly device 30 can be simplified.

Furthermore, in the part assembly device 30 according to the first embodiment, in the second state in which the cap 21 is inserted into the liquid inlet 15, the aspirator flow is sucked in from the sub-path P12 to collect dust around the part assembly site. This allows the area around the part assembly site to be constantly cleaned, reducing the possibility of foreign matter getting into the case 10.

Embodiment 2
In the second embodiment, a component installation device 40 will be described which is another embodiment of the component installation device 30 according to the first embodiment. Note that, although the component installation device 40 will be described as an example in which the cap 21 is inserted downward, the device can also be applied to a case in which the cap 21 is inserted upward.

Figure 5 shows a diagram for explaining the structure of the part assembly device 40 according to the second embodiment. As shown in Figure 5, the part assembly device 40 according to the second embodiment has a holding section 41, a guide section 42, a sliding control section 43, a suction pipe 44, and a blow-out pipe 45. Figure 5 also shows a cap 21 as a part that is transported by the part assembly device 40, and a lid 11 to which the cap 21 is to be assembled.

The holding portion 41 has an adsorption surface at one end for adsorbing the cap 21. The holding portion 41 also has a first opening, a second opening, and an airflow control structure. The first opening is provided on the adsorption surface and applies an adsorption force to the component by airflow in the suction direction. The second opening is provided on the side of the holding portion 41 and draws in airflow in the suction direction. The airflow control structure will be described in detail later.

The guide part 42 grips the side of the holding part 41 that is perpendicular to the adsorption surface so that the holding part 41 can slide in a direction perpendicular to the adsorption surface. This guide part 42 moves from the location where the cap 21 is prepared to the location of the liquid injection hole 15 by a guide part moving means such as a robot arm (not shown).

The sliding control unit 43 slides the holding unit 41 between a first state in which the suction surface is recessed from the end of the guide unit 42 in the sliding direction of the holding unit 41, and a second state in which the suction surface protrudes from the end of the guide unit 42. In FIG. 5, the upper diagram shows the configuration when the part installation device 40 is in the first state, and the lower diagram shows the configuration when the part installation device 40 is in the second state.

The suction pipe 44 supplies airflow in the suction direction. The blow-out pipe 45 supplies airflow in the blow-out direction, which is opposite to the suction direction.

Here, the airflow control structure of the component assembly device 40 according to the second embodiment will be described in detail. The airflow control structure is configured so that the suction force applied to the component by the first opening is smaller in the second state than in the first state, and the airflow sucked in from the second opening is larger in the second state than in the first state.

Specifically, the part assembly device 40 according to the second embodiment has a first pipe P21 and a second pipe P22 as an airflow control structure. The first pipe P21 communicates with the first opening. The second pipe P22 communicates with the second opening. The opening of the first pipe P21 located opposite the first opening is connected to the suction pipe 44 in the first state and is connected to the blow-out pipe 45 in the second state. The opening of the second pipe P22 located opposite the second opening is opened in the first state and is connected to the suction pipe 44 in the second state.

As shown in FIG. 5, in the component assembly device 40 according to the second embodiment, in the first state in which the cap 21 is attached to the suction surface of the holding unit 41 with a strong suction force, the guide unit 42 becomes a wall that covers the periphery of the suction surface, preventing the cap 21 from shifting sideways on the suction surface. In addition, in the first state, the gap between the guide unit 42 and the cap 21 is set to be small. In this way, by setting the area of the suction surface of the holding unit 41 and the area and shape of the suction portion of the cap 21 to be approximately the same, the positional accuracy of the cap 21 relative to the holding unit 41 can be improved. In addition, in the first state, the second opening of the sub-path P22 is blocked by the guide unit 42. In addition, airflow in the suction direction is supplied to the first opening via the first piping P21 and the suction piping 44, generating a strong suction force.

Also, referring to the second state in FIG. 5, in the part assembly device 40 according to the second embodiment, the suction surface of the holding unit 41 protrudes beyond the end of the guide unit 42. Also, in the second state, the first pipe P21 is connected to the blowing pipe 45, and a pushing force is generated in the direction in which the airflow is blown out from the first opening provided on the suction surface of the holding unit 41. As a result, the state of the first pipe P21 is instantly switched from a negative pressure state to a positive pressure state. That is, in the second state of the second embodiment, too, the suction force generated on the suction surface of the holding unit 41 is reduced compared to the first state. On the other hand, in the second state, the second pipe P22 is connected to the suction pipe 44. Therefore, in the second state, the second pipe P22 is supplied with an airflow in the suction direction from the suction pipe 44, and this airflow causes the second opening to collect dust by sucking in the dust around the part mounting site.

When transitioning from the first state to the second state in FIG. 5, a state occurs in which neither the suction pipe 44 nor the blow-out pipe 45 is connected to the first pipe P21 and the second pipe P22. In this state, no suction force is generated on the suction surface of the holding part 41, so the cap 21 slides smoothly sideways on the suction surface. Furthermore, in the second state in the second embodiment, a force pushing the cap 21 from top to bottom is generated by the airflow in the blow-out direction. As a result, in the component assembly device 40 in the second embodiment, when assembling the cap 21 from top to bottom, it is also possible to insert the cap 21 into the liquid injection hole 15 by pushing it in from above.

As explained above, in the part assembly device 40 according to the second embodiment, the suction force on the cap 21 in the second state is less than that in the first state, and since there is no wall around the suction surface to prevent the cap 21 from sliding sideways, the positioning precision required when assembling the cap 21 can be relaxed, as in the first embodiment.

Furthermore, in the component assembly device 40 according to the second embodiment, by applying an airflow in the blowing direction to the cap 21 in the second state, the inside of the first pipe P21 can be instantly switched from a negative pressure to a positive pressure state, thereby improving the removability of the cap 21 in the state where it is adsorbed to the adsorption surface. Also, improving the removability of the cap 21 has the effect of shortening the time required for the assembly process of the cap 21. Also, in the component assembly device 40 according to the second embodiment, by applying an airflow in the blowing direction to the cap 21 in the second state, it is possible to increase the insertion force when inserting the cap 21.

In addition, in the second embodiment, the switching between the suction direction airflow and the blowing direction airflow is performed by the sliding action of the holding part 41. Specifically, in the second embodiment, the sliding action of the holding part 41 switches the connection combination between the first pipe P21 and the second pipe P22 and the suction pipe 44 and the blowing pipe 45. As a result, in the part assembly device 40 according to the second embodiment, it is not necessary to switch valves or switch the generated airflow to switch the airflow direction, and therefore the configuration of the device can be simplified.

The present invention is not limited to the above embodiment, and can be modified as appropriate without departing from the spirit and scope of the invention.
