DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] <Embodiment> The chained terminal of this embodiment includes a plurality of terminals 1 connected to a band-shaped linking portion 10 via a linking portion 2, and a plurality of band-shaped subcarriers 21 of a predetermined length. Specifically, the chained terminal is configured by connecting a pair of subcarriers 21 adjacent to each other in the transport direction of the chained terminal (see arrow Y1 in FIG. 1) by each of the linking portions 10 (see FIG. 2). The plate thickness of the subcarriers 21 is configured to be smaller than the plate thickness of the metal plate forming the terminal 1. The subcarriers 21 are arranged such that the longitudinal direction of the subcarriers 21 is aligned with the transport direction of the chained terminal. Here, the subcarriers 21 may be made of a metal plate or a resin plate. The predetermined length (longitudinal length) of the plurality of subcarriers 21 is appropriately determined based on the pitch (spacing) between the terminals 1, the shape of the terminals 1, and the like.
[0013] The manufacturing apparatus of this embodiment has a chained terminal primary processing means and a chained terminal secondary processing means. First, as shown in Fig. 1, the primary chain terminal processing means presses a thick metal plate into a chain terminal having a strip-shaped linking portion 10 and a plurality of terminals 1 connected to the linking portion 10 via linking portions 2. During this press processing, one pilot hole 11 is formed for each terminal 1 in the linking portion 10.
[0014] Next, the chained terminal secondary processing means separates the chained portion 10 of the chained terminal processed by the chained terminal primary processing means in its longitudinal direction into each terminal 1 (the form in Figs. 1 and 2). Then, each separated chained portion 10 is press-processed. During this press processing, a plurality of connection holes (small holes) 12 (four in this example) are processed in the chained portion 10. Then, each chained portion 10 provided with the connection holes 12 is joined to a pair of subcarriers 21 adjacent to each other in the conveying direction (see arrow Y1 in Fig. 1) among the plurality of subcarriers 21 by fitting and crimping a protrusion formed in the plate thickness direction and the small hole, and the chained portions are again formed into a chain.
[0015] That is, when the multiple subcarriers 21 are processed, each subcarrier 21 is provided with a protrusion 22 corresponding to the connection hole 12 of the linking portion 10. Then, the four connection holes 12 are fitted into the two protrusions 22 (four protrusions 22 in total) of each subcarrier 21, and the protrusions 22 are crimped so that the linking portion 10 straddles the pair of subcarriers 21. In this way, the multiple subcarriers 21 and the terminals 1 are connected via each of the separated linking portions 10. As a result, the multiple subcarriers 21 are linked in the conveyance direction by each linking portion 10, and are connected to the terminals 1 as a new linking portion 20.
[0016] The terminal 1 with the separated linking portion 10 is pushed and moved by a pushing member (not shown) so as to straddle the pair of adjacent subcarriers 21 and positioned on the pair of subcarriers 21. Then, the four connection holes 12 provided in the linking portion 10 are fitted into the two protruding portions 22 (total of four protruding portions 22) of each subcarrier 21, respectively, and in this state, the protruding portions 22 are crimped by a crimping member (not shown), thereby connecting the terminal 1 to the plurality of subcarriers 21 via the separated linking portion 10. In this way, a chained terminal made of a composite material is completed, in which the terminal 1 is made of a thick metal plate and the linking portion 20 (the plurality of subcarriers 21) is made of a strip-shaped plate member of a predetermined length. Here, the protruding portions 22 may be formed by burring processing or dowel processing.
[0017] Laser welding may be used as a method for connecting the linking portion 10 and the subcarrier 21 (see FIG. 4). Alternatively, instead of the protrusion 22, a hole 22a corresponding to the connection hole 12 may be provided in the subcarrier 21, and the linking portion 10 and the subcarrier 21 may be fastened together and connected by a band B or the like (see FIG. 5). Alternatively, a crimping portion 10a may be provided in the linking portion 10, and the linking portion 10 and the subcarrier 21 may be connected by crimping the crimping portion 10a to the subcarrier 21 as shown in FIG. 8. In this way, the method for connecting the linking portion 10 and the subcarrier 21 is not particularly limited as long as it can realize the present invention.
[0018] FIG. 3 is a block diagram of a manufacturing system 200 including the manufacturing apparatus according to the embodiment. As shown in Figure 3(a), the manufacturing system 200 is mainly composed of a progressive die type press device 100 as a manufacturing device for chained terminals of the embodiment, and is equipped with a terminal material supply device 101, a material feed device 102, a product discharge device 104, and a product winding device 105.
[0019] The terminal material supplying device 101 supplies material for the terminal 1. The material feeding device 102 sends the material supplied by the terminal material supplying device 101 to the press device 100. The press device 100 forms a chained terminal, which is a product manufactured by this manufacturing system 200. The product manufactured by the press device 100 is discharged by a product discharging device 104 and wound up by a product winding device 105.
[0020] In this embodiment, as shown in FIG. 3(b), the press device 100 is provided with a terminal forming mechanism 131 as a primary chained terminal processing means, and a sub-carrier supply mechanism 132 and a chaining mechanism 133 as secondary chained terminal processing means.
[0021] The terminal forming mechanism 131 forms a plurality of terminals 1 connected to the chain portion 10 via the link portion 2. In this example, the subcarrier supply mechanism 132 supplies a plurality of subcarriers 21 to the chaining mechanism 133 along a direction (see arrow Y2 in FIG. 1) perpendicular to the conveying direction (see arrow Y1 in FIG. 1) of the chained terminals. The chaining mechanism 133 separates the chained terminals processed by the terminal forming mechanism 131 into each terminal 1 in the longitudinal direction, and crimps a pair of subcarriers 21 adjacent to each other in the conveying direction among the plurality of subcarriers 21 supplied from the subcarrier supply mechanism 132 in a state in which the connection holes 12 of the chain portion 10 are fitted into the two convex portions 22 of the pair of convex portions 22 of each subcarrier 21 so as to connect the plurality of terminals 1 in the conveying direction via each of the chain portions 10 (see FIGS. 1 and 2). In this manner, the chained terminals are manufactured in the press device 100.
[0022] It should be noted that the two convex portions 22 that form a pair among the convex portions 22 of each subcarrier 21 refer to the two convex portions 22 on the right side of the paper in the subcarrier 21 on the left side of the paper, and the two convex portions 22 on the left side of the paper in the subcarrier 21 on the right side of the paper, as shown in FIG. 2.
[0023] Incidentally, after the product manufactured by the press device 100 is wound by the product winding device 105, there are, for example, post-processes such as a plating process for plating the terminals 1, a crimping process for crimping electric wires or the like to the terminals 1, and a transporting process for transporting the product to a facility (location) for carrying out these post-processes. In the above-mentioned post-processes, by chaining the terminals 1 as described above, workability is superior to the case where multiple terminals are handled one by one. Furthermore, by chaining the terminals 1, the above-mentioned post-processes can be automated.
[0024] In addition, when removing the terminal 1 from the multiple subcarriers 21 (chain portion 20) in the above-mentioned post-process, it may be removed by cutting the connecting portion 2, or it may be removed by releasing the connection between the chain portion 10 and the multiple subcarriers 21 (chain portion 20) by a predetermined method. Therefore, the connection between the chain portion 10 and the multiple subcarriers 21 (chain portion 20) may be connected so as to be releaseable by a predetermined method.
[0025] As an example of the post-process, a plating process will be described with reference to FIGS. Fig. 6 is a block diagram of a plating system 300 including a plating apparatus used in the plating process, which is one of the above-mentioned post-processes. Fig. 7 is a schematic diagram of the plating apparatus. The plating system 300 is mainly configured with a plating device 107 that performs plating on the chained terminals 1 (chained terminals) as described above, and also includes a product unwinding device 106 and a product winding device 108.
[0026] The product unwinding device 106 sends the product manufactured by the press device 100 and wound up by the product winding device 105 to the plating processing device 107. The plating processing device 107 plate the terminals 1 of the chain terminals, which are the products. The product unwinding device 108 winds up the product plated by the plating processing device 107.
[0027] 7, for example, a plating layer is formed on the surface of the terminal 1 by immersing the terminal 1 in plating 31 placed in a tank in a plating processing device 107. The plating processing device 107 is provided with guide rollers 32 that send the product to a product unwinding device 108 and prevent the terminal 1 from floating up from the plating 31.
[0028] Between the product winding device 105 and the product unwinding device 106, the product may be transported from one facility (location) where the product winding device 105 is installed to another facility (location) where the product unwinding device 106 is installed. Also, the product winding device 105 and the product unwinding device 106 may be installed in the same facility (location), and the manufacture of the product of the embodiment and the plating process may be carried out in a continuous flow.
[0029] According to the above configuration, the terminal 1 can be connected to the linking part 20 (plurality of subcarriers 21) having a plate thickness smaller than that of the terminal 1, so that the burden when winding the linking part 20 can be reduced. In addition, since the occurrence of curling can be reduced, the burden when correcting the curling in a later process can be reduced or eliminated. Furthermore, since the linking part 20 is formed by the plurality of subcarriers 21 of a predetermined length, the linking part 20 (i.e., the plurality of subcarriers 21) is easier to handle than when a plate material having a length is used as in the conventional linking part (carrier).
[0030] Furthermore, according to the above configuration, the press device 100 is provided with the sub-carrier supply mechanism 132, so that a series of manufacturing steps including terminal formation, sub-carrier supply, and chaining can be smoothly carried out.
[0031] Furthermore, according to the above configuration, the subcarrier supply mechanism 132 supplies multiple subcarriers 21 to the chaining mechanism along a direction perpendicular to the transport direction, thereby shortening the supply (transport) section from the subcarrier supply mechanism 132 to the chaining mechanism 133.
[0032] <Other forms> The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.
