For clarity of explanation, the following descriptions and drawings are omitted and simplified as appropriate. In each drawing, the same elements are denoted by the same reference numerals, and redundant description is omitted as necessary.

Embodiment 1
First, the parts assembling apparatus according to the first embodiment is used in manufacturing secondary batteries. In the following description, a parts assembling apparatus that assembles a cap that prevents dust from entering during welding in assembling a secondary battery will be described. Note that the parts to be assembled by the parts assembling apparatus can be any parts as long as they require positioning accuracy and can be held by suction. Therefore, in order to explain the parts to be assembled by the parts assembling apparatus according to the first embodiment, first, the configuration of the secondary battery will be described. In addition, although the component assembling apparatus 30 described below assembles such that the cap 21 is inserted downward, the insertion direction of the cap 21 is not particularly limited.

FIG. 1 shows a schematic diagram of a secondary battery according to a first embodiment. As shown in FIG. 1 , secondary battery 1 according to the first embodiment has case 10 and lid 11 . A power body is housed in the case 10 . The lid 11 seals the case 10 in a state where the power body is housed in the case 10 . A negative terminal 12 and a positive terminal 13 are provided on the lid 11 . The negative electrode terminal 12 is an electrode that takes out electric power from the negative electrode of the power body in the case 10, and is joined to a negative electrode pole provided penetrating the lid 11 by a negative electrode crimp tool 12a. The negative electrode pole, 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 takes out electric power from the positive electrode of the power body in the case 10, and is joined to a positive electrode column provided penetrating the lid 11 by a positive electrode caulking tool 13a. The positive pole, the positive crimp tool 13a, and the positive terminal 13 are joined by laser welding.

Further, the lid 11 is provided with an open valve 14 and an injection hole 15 . The open valve 14 is a valve that reduces the internal pressure of the sealed case 10 when the internal pressure inside the case 10 reaches a certain level or higher. The injection hole 15 is a hole provided for injecting the electrolytic solution into the case 10, and is sealed by the sealing member 22 after the injection. However, since the electrolytic solution 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 , dust will flow through the injection hole 15 into the case 10 . There is a risk of intrusion inside. Therefore, in the manufacturing process of the secondary battery, when the lid 11 is welded to the case 10 , the cap 21 is fitted into the injection hole 15 to prevent dust from entering the case 10 through the injection hole 15 .

Here, FIG. 2 shows a flow chart 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, the current collector is welded to the electrode body, the current collector is welded to the electrode penetrating the lid 11, and the electrode body is housed in the case 10. A member assembling process is carried out to cover the opening of the case 10 with the lid 11 (step S1). Subsequently, the cap 21 is inserted into the injection hole 15 of the lid 11 (step S2). Subsequently, the case 10 and the lid 11 are welded together (step S3). Subsequently, the cap 21 is removed from the injection hole 15, and the electrolytic solution is injected into the case 10 through the injection hole 15 (step S4). Subsequently, the cover 11 and the injection hole 15 are welded together with the sealing member 22 placed in the injection hole 15, thereby sealing the injection hole 15 with the sealing member 22 (step S5). This completes the process of assembling the secondary battery. In such a process, the parts assembling apparatus according to the first embodiment is used in the process of inserting the cap 21 into the injection hole 15 in step S2.

A component assembling apparatus 30 according to the second embodiment will be described in detail. FIG. 3 shows a diagram for explaining the structure of the component assembling apparatus 30 according to the first embodiment. As shown in FIG. 3, the component assembling apparatus 30 according to the first embodiment has a holding section 31, a guide section 32, and a slide control section 33. As shown in FIG. FIG. 3 also shows the cap 21 as a component transported by the component assembly apparatus 30 and the lid 11 to which the cap 21 is to be assembled.

The holding portion 31 is provided at one end with a suction surface for sucking the cap 21 . Moreover, the holding part 31 has a first opening, a second opening, and an airflow control structure. The first opening is provided on the attracting surface and applies an attracting force to the component by an airflow in the attracting direction. The second opening is provided on the side surface of the holding portion 31 and sucks the airflow in the suction direction. Details of the airflow control structure will be described later.

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

The slide control unit 33 moves the holding portion 31 into a first state in which the suction surface is buried below the end of the guide portion 32 in the sliding direction of the holding portion 31 , and a first state in which the suction surface is buried below the end of the guide portion 32 in the sliding direction. and a second state of protruding. In FIG. 3, the upper diagram shows the configuration when the component assembling device 30 is in the first state, and the lower diagram illustrates the configuration when the component assembling device 30 is in the second state.

Here, the airflow control structure of the parts assembling apparatus 30 according to the first embodiment will be described in detail. The airflow control structure makes the suction force applied to the component by the first opening smaller in the second state than in the first state, and the airflow sucked from the second opening is the first state. Make it larger in the second state than in the state.

Specifically, the component assembling apparatus 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 subpath P12 communicates the main path P11 and the second opening. The second opening is provided at a position where it is covered by the guide portion 32 in the first state and exposed in the second state. Moreover, it is preferable that the cross-sectional area of the main path P11 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 component assembling apparatus 30 weakens the attracting force of the attracting surface in the second state compared to the first state, 21 can be maintained.

As shown in FIG. 3, in the component assembling apparatus 30 according to the first embodiment, in the first state in which the cap 21 is attracted to the attraction surface of the holding portion 31 with a strong attraction force, the guide portion 32 is positioned at the attraction surface. and prevents the cap 21 from laterally slipping on the suction surface. Also, in the first state, the gap between the guide portion 32 and the cap 21 is set to be small. By setting the area of the attracting surface of the holding portion 31 and the area and shape of the attracting portion of the cap 21 to be substantially the same as described above, the positional accuracy of the cap 21 with respect to the holding portion 31 can be improved. Note that in the first state, the second opening of the sub-path P12 is blocked by the guide portion 32, and a strong adsorption force is generated in the first opening.

Further, referring to the second state of FIG. 3, in the component assembling apparatus 30 according to the first embodiment, the suction surface of the holding portion 31 protrudes from the end portion of the guide portion 32, and the second opening is exposed. state. 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 air current flowing through the sub-path P12 causes the component mounting apparatus 30 to collect dust around the mounting position of the cap 21 and discharge it to the outside. This dust may include sliding dust from the component assembling device 30, dust from the cell clamp jig, dust related to the cap, and the like.

In addition, in the second state of FIG. 3, since the airflow sucked from the first opening is smaller than in the first state, the suction force generated on the adsorption surface of the holding portion 31 is smaller than in the first state. In the second state, the suction surface of the holding portion 31 protrudes from the end portion of the guide portion 32 . As a result, in the component assembling apparatus 30 according to the first embodiment, there is no wall around the holding portion 31 in the second state, so that the cap 21 can slide sideways on the attracting surface. This side slip will be described with reference to FIG.

FIG. 4 shows a diagram for explaining the side-slip effect of the parts assembling apparatus 30 according to the first embodiment. FIG. 4 shows, as a comparative example, a component assembling apparatus 300 in which side walls are fixedly provided around the attracting surface to prevent side slip of the cap 21 in order to explain the effect of the side slip.

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 injection hole 15 within the width of the taper, the cap 21 is inserted into the injection hole 15 while being laterally shifted along the taper. At this time, in the component assembling apparatus 30, there is nothing around the attracting surface of the holding portion 31 that hinders the lateral displacement of the cap 21 in the second state. Further, in the component assembling apparatus 30 according to the first embodiment, the attraction force for attracting the cap 21 to the attraction surface of the holding portion 31 is weaker in the second state than in the first state. Therefore, in the component assembling apparatus 30 according to the second embodiment, the lateral displacement of the cap 21 occurs smoothly, and the cap 21 is accurately fitted into the injection hole 15 .

On the other hand, in the comparative example, lateral displacement of the cap 21 is restricted by side walls provided around the suction surface of the component assembling apparatus 300 . Therefore, in the case of using the parts assembling apparatus 300 according to the comparative example, in order to accurately insert the cap 21 into the injection hole 15, the relative position accuracy (accuracy of aligning the central axis) between the parts assembling apparatus 300 and the cap 21 is required. , and the accuracy of aligning the center axes of the parts assembling device 300 and the injection hole 15 must be highly controlled.

As described above, in the component assembling apparatus 30 according to the first embodiment, a large lateral deviation width of the cap 21 can be obtained in the second state. Therefore, by using the parts assembling apparatus 30 according to the first embodiment, it is possible to relax the alignment accuracy between the central axis of the cap 21 and the central axis of the injection hole 15 .

In addition, by relaxing the centering accuracy, a wider tolerance can be obtained for the size of the cap 21 and the injection hole 15, so that the member cost can be reduced. Furthermore, by relaxing the centering accuracy, it is possible to reduce the adjustment time for moving the component mounting device 30 to the mounting position and the manufacturing cost of the component mounting device 30 .

Further, in the component assembling apparatus 30 according to the first embodiment, the pressure of the suction airflow supplied to the main path P11 is reduced in order to attenuate the suction force in order to increase the side-slipping property of the cap 21 on the suction surface of the holding portion 31. No need. As a result, in the parts assembling apparatus 30 according to the first embodiment, the parts assembling cycle time can be shortened. In addition, since there is no need to depressurize the aspirator flow, the configuration of the parts assembling device 30 can be simplified.

Furthermore, in the component assembling apparatus 30 according to the first embodiment, in the second state in which the cap 21 is inserted into the injection hole 15, the aspirator flow is sucked from the secondary path P12, thereby collecting dust around the site assembling site. conduct. As a result, it is possible to constantly clean the area around the component assembly site, so that the possibility of foreign matter entering the case 10 can be reduced.

Embodiment 2
In the second embodiment, a parts assembling apparatus 40 that is another form of the parts assembling apparatus 30 according to the first embodiment will be described. Note that the component assembling apparatus 40 will be described as an example in which the cap 21 is inserted downward, but it can also be applied when the cap 21 is inserted upward.

FIG. 5 shows a diagram for explaining the structure of a component assembling apparatus 40 according to the second embodiment. As shown in FIG. 5, the component assembling apparatus 40 according to the second embodiment has a holding portion 41, a guide portion 42, a slide control portion 43, a suction pipe 44, and a blowout pipe 45. As shown in FIG. FIG. 5 also shows the cap 21 as a component conveyed by the component assembly apparatus 40 and the lid 11 to which the cap 21 is to be assembled.

The holding portion 41 is provided with a suction surface for sucking the cap 21 at one end. Moreover, the holding part 41 has a first opening, a second opening, and an airflow control structure. The first opening is provided on the attracting surface and applies an attracting force to the component by an airflow in the attracting direction. The second opening is provided on the side surface of the holding portion 41 and sucks the airflow in the suction direction. Details of the airflow control structure will be described later.

The guide portion 42 grips a side surface of the holding portion 41 perpendicular to the suction surface so that the holding portion 41 can slide in a direction perpendicular to the suction surface. This guide portion 42 is moved from the place where the cap 21 is prepared to the position where the injection hole 15 is located by guide portion moving means such as a robot arm (not shown).

The sliding control unit 43 moves the holding portion 41 into a first state in which the suction surface is buried below the end of the guide portion 42 in the sliding direction of the holding portion 41 , and a first state in which the suction surface is buried below the end of the guide portion 42 in the sliding direction. and a second state of protruding. In FIG. 5, the upper diagram shows the configuration when the component assembling device 40 is in the first state, and the lower diagram illustrates the configuration when the component assembling device 40 is in the second state.

The suction pipe 44 supplies airflow in the suction direction. The blowout pipe 45 supplies airflow in the blowout direction opposite to the suction direction.

Here, the airflow control structure of the parts assembling apparatus 40 according to the second embodiment will be described in detail. The airflow control structure makes the suction force applied to the component by the first opening smaller in the second state than in the first state, and the airflow sucked from the second opening is the first state. Make it larger in the second state than in the state.

Specifically, the component assembling apparatus 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 opposite to the first opening is connected to the suction pipe 44 in the first state and is connected to the blowout pipe 45 in the second state. . The opening of the second pipe P22 opposite to 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 assembling apparatus 40 according to the second embodiment, in the first state in which the cap 21 is attracted to the attraction surface of the holding portion 41 with a strong attraction force, the guide portion 42 is positioned at the attraction surface. and prevents the cap 21 from laterally slipping on the suction surface. Also, in the first state, the gap between the guide portion 42 and the cap 21 is set to be small. By setting the area of the attracting surface of the holding portion 41 and the area and shape of the attracting portion of the cap 21 to be substantially the same as described above, the positional accuracy of the cap 21 with respect to the holding portion 41 can be improved. In addition, in the first state, the second opening of the secondary path P22 is blocked by the guide portion 42 . Also, an air flow in the suction direction is supplied to the first opening via the first pipe P21 and the suction pipe 44 to generate a strong suction force.

Further, referring to the second state of FIG. 5 , in the component assembling apparatus 40 according to the second embodiment, the suction surface of the holding portion 41 protrudes from the end portion of the guide portion 42 . Further, in the second state, the first pipe P21 is connected to the blowout pipe 45, so that a pushing force is generated in the direction in which the airflow blows out from the first opening provided in the adsorption surface of the holding portion 41. As shown in FIG. As a result, the state of the first pipe P21 is immediately switched from the negative pressure state to the positive pressure state. That is, in the second state also in the second embodiment, the attracting force generated on the attracting surface of the holding portion 41 is smaller than that in the first state. On the other hand, the second pipe P22 is connected to the suction pipe 44 in the second state. Therefore, in the second state, an airflow in the suction direction is supplied from the suction pipe 44 to the second pipe P22, and this airflow collects dust by sucking dust around the component mounting portion through the second opening. .

Further, when the first state shown in FIG. 5 is changed to the second state, a state occurs in which neither the suction pipe 44 nor the blow pipe 45 is connected to the first pipe P21 and the second pipe P22. In this state, since no attraction force is generated on the attraction surface of the holding portion 41, the cap 21 slides smoothly on the attraction surface. Furthermore, in the second embodiment, in the second state, a force that pushes the cap 21 downward is generated by the airflow in the blowing direction. As a result, in the component assembling apparatus 40 according to the second embodiment, when assembling the cap 21 from top to bottom, it is also possible to insert the cap 21 into the injection hole 15 so as to push the cap 21 from above.

From the above description, also in the component assembling apparatus 40 according to the second embodiment, the attraction force to the cap 21 in the second state is smaller than that in the first state, and the lateral slippage of the cap 21 around the attraction surface is prevented. Since there is no obstructive wall, the positioning accuracy when assembling the cap 21 can be relaxed as in the first embodiment.

Furthermore, in the parts assembling apparatus 40 according to the second embodiment, by applying the airflow in the blowing direction to the cap 21 in the second state, the inside of the first pipe P21 can be immediately switched from the negative pressure to the positive pressure state. Therefore, it is possible to improve the releasability of the cap 21 in a state of being adsorbed by the adsorption surface. In addition, the improvement in peelability of the cap 21 produces an effect of shortening the time required for the process of assembling the cap 21 . Further, in the component assembling apparatus 40 according to the second embodiment, by applying the 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 .

Further, in the second embodiment, the airflow in the suction direction and the airflow in the blowing direction are switched by sliding movement of the holding portion 41 . Specifically, in the second embodiment, the connection combination of the first pipe P21 and the second pipe P22 and the suction pipe 44 and the blow pipe 45 is switched by sliding the holding portion 41 . As a result, in the parts assembling apparatus 40 according to the second embodiment, there is no need to switch valves or to switch the generated airflow in order to switch the direction of the airflow, so the configuration of the apparatus can be simplified. can.

It should be noted that the present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the scope of the invention.
