  Hereinafter, preferred embodiments of a battery assembling apparatus according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1 and FIG. 2, when a battery unit U is formed by assembling a resin frame (first frame) 2 and a battery 3, the assembled battery 1 includes a plurality of battery units U. They are arranged in series. When the end unit R is an assembly of the end plate 4 (see FIG. 3), which is an example of the second frame body used at both ends of the assembled battery 1, and the battery 3, the assembled battery 1 At both ends, end units R are arranged. The end plate 4 has a configuration in which a resin frame 4A and a metal end frame 4B are integrated.

  The assembled battery 1 having such a configuration is assembled in the battery production line M. When the assembled battery 1 is assembled, first, the battery unit U and the end unit R must be manufactured. The battery assembling apparatus 5 used for this includes a frame body receiving portion A for selectively receiving the resin frames 2 and end plates 4 arranged in a row by the chuck portion 20, and the batteries 3 arranged in a row. A battery receiving part B for receiving the chuck part 10; a unit assembly part C for assembling the resin frame 2 or end plate 4 held by the chuck part 20 and the battery 3 held by the chuck part 10; have.

  The battery assembly method by the battery assembly apparatus 5 will be briefly described. First, the resin frame 2 is received by the chuck unit 20 in the frame body reception unit A. Further, the battery 3 is received by the chuck portion 10 in the battery receiving portion B. Thereafter, in the unit assembly portion C, the resin frame 2 held by the chuck portion 20 and the battery 3 held by the chuck portion 10 are assembled so as to match. The resin frame 2 is provided with hooks (not shown) that can be hooked, and the battery 3 is assembled to the resin frame 2 with one touch. Similarly, in the case of the end plate 4, the end unit R is assembled in the unit assembly portion C by one touch.

  The battery unit U and the end unit R assembled in this way are transferred to the battery stacking device 12 of the battery assembly line M by a conveyor, and the battery units U are sequentially stacked with the end unit R installed at one end. I will let you. Then, after a predetermined number of battery units U are stacked, another end unit R is installed at the other end, whereby a series of manufacture of the assembled battery 1 is completed.

Here, in the unit assembly portion C (see FIG. 1), when the resin frame 2 held by the chuck portion 20 and the battery 3 held by the chuck portion 10 are assembled so as to match each other, Unless supported from the back surface 2b side, the battery 3 cannot be pushed into the first battery assembly portion 2S of the resin frame 2. The same applies to the end plate 4. Therefore, in order to simplify the apparatus configuration, the resin frame 2 and the end plate 4 having different shapes need to be shared and held by one chuck portion 20.

  Therefore, the chuck unit 20 that can be shared will be described. The resin frame 2 used in the battery assembling apparatus 5 is provided with a concave first battery assembling portion 2S on the surface 2a side, and the end plate 4 has a concave second on the surface 4a side. Battery assembly portion 4S is provided (see FIGS. 2 and 3).

  As shown in FIGS. 4 and 5, the chuck portion 20 fixed to the tip of a rotating arm (not shown) includes a gripping portion 21 for supporting the resin frame 2 and the end plate 4 on the left and right sides, and the resin frame 2. The movable block 22 is in contact with the back surface 2b (see FIG. 2), and the fixed block 23 is in contact with the back surface 4b of the end plate 4 (see FIG. 3). The movable block 22 is retracted to a non-contact position where the fixed block 23 does not contact the back surface 4 b of the end plate 4 when the fixed block 23 contacts the back surface 4 b of the end plate 4.

  The grip portion 21 includes a flat plate-like main portion 21a and a hand portion 21b that protrudes forward on the left and right of the main portion 21a. A finger part 21c shared to support the resin frame 2 and the end plate 4 is provided at the tip of the hand part 21b. The resin frame 2 and the end plate 4 are supported from both the left and right sides by the pair of left and right fingers 21c and positioned.

  The fixed block 23 has a rectangular parallelepiped shape and is fixed to the main portion 21a of the grip portion 21 with screws or the like. A rectangular contact surface 23 a is provided at the front end of the fixed block 23.

  The movable block 22 is disposed above the fixed block 23. The rear portion of the movable block 22 is attached to the upper end surface of the main portion 21a of the grip portion 21 via a hinge portion 24 having a rotation shaft 24a. The movable block 22 can be rotated upward about the hinge portion 24. The rear end surface 22b of the movable block 22 abuts on the front surface 21e of the main portion 21a of the grip portion 21, so that the movable block 22 22 is maintained in a horizontal state. A laterally long contact surface 22 a is provided at the front end of the movable block 22.

  As shown in FIGS. 4 to 6, the movable block 22 is provided with an operation portion 26, and the operation portion 26 is a rib 4 c that is an example of a convex portion that extends in the vertical direction on the back surface 4 b of the end plate 4. (See FIG. 3). When the back surface 4b of the end plate 4 and the movable block 22 approach each other, the operation unit 26 contacts the free end 4d of the rib 4c and is used for rotating the movable block 22. The pair of left and right ribs 4c are erected so as to protrude rearward with a metal end frame 4B.

  The operation unit 26 is a flip-up pin that protrudes upward from the upper surface of the movable block 22 and has a simple configuration. The flip-up pin 26 is engaged with the free end 4d of the rib 4c of the end plate 4 when the end plate 4 approaches the chuck portion 20 at the frame receiving portion A (see FIG. 1). This is for rotating the movable block 22 upward (see FIG. 6).

  The flip-up pin (operation part) 26 bent at a right angle is composed of a support part 26a erected on the upper surface of the movable block 22, and an engagement part 26b extending in the horizontal direction from the upper end of the support part 26a. . The flip-up pins 26 are disposed on the left and right of the upper surface of the movable block 22 with a mirror-symmetrical relationship. The engaging portions 26b of the flip-up pins 26 extend so as to extend in the left and right directions, so that each engaging portion 26b can easily hit the free end 4d of the rib 4c of the end plate 4.

  As shown in FIG. 7, such a flip-up pin 26 does not operate when the movable block 22 is brought into contact with the back surface 2b (see FIG. 2) of the resin frame 2, and the back surface 4b of the end plate 4 ( It operates when the fixed block 23 is brought into contact with (see FIG. 3). The jumping up of the rotating block 22 by the operation of the flip-up pin 26 is made by paying attention to the difference between the thickness M1 of the battery facing portion 2R of the resin frame 2 and the thickness M1 of the battery facing portion 4R of the end plate 4. Yes.

  That is, when the battery facing portion 2R of the resin frame 2 is set on the mounting surface 21d provided at the tip of the hand portion 21b of the chuck portion 20, the battery facing portion 4R of the end plate 4 is the hand portion of the chuck portion 20. The position P1 of the back surface 2b of the resin frame 2 and the position P2 of the back surface 4b of the end plate 4 are different from the case where it is set on the mounting surface 21d of 21b. Focusing on this point, as shown in FIG. 5, the dimensional difference L between the contact surface 22a of the movable block 22 and the contact surface 23a of the fixed block 23 is set to thickness (M2) −thickness (M1). doing.

  Next, the operation when the chuck portion 20 receives the resin frame 2 or the end plate 4 in the frame body receiving portion A (see FIG. 1) will be described.

  As shown in FIG. 6, when the end plate 4 is pushed out toward the chuck portion 20 in the frame body receiving portion A, the flip-up pin 26 is moved to the free end 4 d of the rib 4 c of the end plate 4. The engaging part 26b contacts. Furthermore, as the end plate 4 approaches the chuck portion 20, the engaging portion 26b rises so as to slide along the free end 4d of the rib 4c of the end plate 4, and accordingly, the movable block 22 moves upward. Rotate. Finally, the movable block 22 retracts to a non-contact position where it does not contact the back surface 4 b of the end plate 4 when the fixed block 23 contacts the back surface 4 b of the end plate 4.

  By such an operation, the contact surface 23a of the fixed block 23 is brought into contact with the back surface 4b of the end plate 4 in the frame body receiving part A (see FIG. 1), and this state is maintained. Accordingly, the lip portion 30 protruding into the battery assembly portion 4S of the end plate 4 can be reliably crushed by the pushing operation of the battery 3 in the unit assembly portion C.

  As shown in FIG. 8, in the frame body receiving part A, even when the resin frame 2 approaches the chuck part 20 in the direction of the arrow, the movable block 22 does not jump up, and the contact surface of the movable block 22 The back surface 2b of the resin frame 2 comes into contact with 22a.

  As shown in FIG. 9, the resin frame 2 is transferred to the unit assembly part C in this state, and the battery 3 is pushed into the battery assembly part 2 </ b> S of the resin frame 2. At this time, the lip portion 31 protruding into the battery assembly portion 2S of the resin frame 2 can be reliably crushed by the pushing operation of the battery 3.

  In the battery assembling apparatus 5 described above, the fixed block 23 and the movable block 22 are adopted. When the fixed block 23 comes into contact with the back surface 4b of the end plate (second frame) 4, The end plate 4 is retracted to a non-contact position where it does not contact the back surface 4b. In this way, the state in which the movable block 22 abuts on the back surface 2b of the resin frame (first frame body) 2 and the state in which the fixed block abuts on the back surface 4b of the end plate 4 can be achieved with one device 5. Can be realized. In other words, the assembly of the resin frame 2 and the battery 3 and the assembly of the end plate 4 and the battery 3 can be selectively performed with one chuck portion 20. When the battery 3 is selectively assembled to the battery 3, the apparatus 1 can be shared, and the apparatus configuration can be simplified.
