A shaped opening 63 is formed in the longitudinal direction. Note that the opening 63 has the same length as the slit 61 as an example.

  FIG. 10 shows a method of detaching the second electrode mounting plate 53 from the first electrode mounting plate 51. The second electrode mounting plate 53 in a set of two sheets is made of a rectangular plate material smaller than the opening 63, and has a longitudinal direction. One bolt insertion hole 65 is provided at the center of both ends in the direction corresponding to the second slit 61. The bolt 29 passes through the slit 61 from the bolt insertion hole 65 of the upper second electrode mounting plate 53 and passes through the bolt insertion hole 65 of the lower second electrode mounting plate 53. As shown in FIG. 4, the nut 31 is screwed onto the shaft portion 29 a of the bolt 29 protruding downward from the bolt insertion hole 65 of the lower second electrode mounting plate 53.

  Therefore, when the bolt 29 and the nut 31 are loosened, the two second electrode mounting plates 53 can move together along the slit 61, and when the nut 31 is tightened on the bolt 29, the upper and lower second electrode mounting plates 53 are attached. The plate 53 is fixed to the first electrode mounting plate 51 at an arbitrary position.

  Further, as described above, the second electrode mounting plate 53 is formed smaller than the opening 63.

  The moving table 7 is connected to the base 1 by the slider 5, but as shown in FIGS. 1 and 2, the left and right side portions between the moving table 7 and the base 1 are further provided with three pieces. Links (rods) 67, 69, 71 are connected by pins 73 in a substantially Z shape when viewed from the side.

  Of the three links 67, 69, 71 on the left and right, the longest link 67 is connected to the side of the leg 11 of the base 1 with a pin 73 at the lower end, and the upper end is connected to the upper end of the link 69. They are connected by pins 73. As shown in FIG. 1, when the mount device 3 is not used, the link 67 is inclined at the upper end side toward the rear of the base 1, and the link 69 connected thereto is inclined obliquely downward toward the front of the base 1. The lower end side of the link 69 and the lower end side of the link 71 are connected to the side portions of the side frames 41 a and 41 c by pins 73, respectively, and the upper end side of the link 71 is inclined obliquely toward the rear of the base 1. As an example, the links 69 and 71 have the same shape.

  A cylindrical operation bar 75 is installed between the upper ends of the left and right links 71, and in this embodiment, these links 67, 69, 71 and the slider 5 are used to move the moving base relative to the base 1. A toggle mechanism T for moving 7 up and down is formed.

  11, 12, and 13 show a state where the electrode 55 of the charge / discharge test apparatus is connected to the electric energy 77 of the secondary battery 15 using the mount device 3 shown in FIG. 1. When the operation bar 75 is moved forward of the base 1 as shown in FIGS. 11 and 12 from the unused state of the mounting device 3 in FIG. 1, the circular motion of the operation bar 75 is translated along the slider 5 by the toggle mechanism T. Converted into movement. Then, in conjunction with the operation of the operation bar 75, the moving base 7 is raised until the links 69 and 71 overlap each other and stand upward, and the link 71 is inclined forward of the mount device 3 as shown in FIG. As the time goes, the movable table 7 is lowered. Then, when the link 71 comes into contact with the stopper 79 provided on the side frames 41a and 41c, the moving table 7 that descends stops, so that the top dead center and the bottom dead center of the electrode 55 attached to the moving table 7 are physically changed. Will be determined.

  The mount device 3 according to the present embodiment has the structure shown in FIGS. 1 to 13. To perform a charge / discharge test of the secondary battery 15 using the mount device 3, first, the entire mount device 3 is used. The bolts 29 and 59 and the nut 31 are loosened, and the pair of holding metal fittings 19 and 21 are slid forward and rearward of the base 1 respectively.

  As a fixing method of the secondary battery 15, first, the height of the lifting bracket 23 is adjusted according to the height of the secondary battery 15. Since the bottom dead center of the position of the electrode 55 (electrode position) is determined in advance by the toggle mechanism T as described above, the lifting bracket 23 slides so that the electrode 77 of the secondary battery 15 comes to the position of the bottom dead center. It is moved up and down along 35. Then, at the position where the electrode 77 of the secondary battery 15 comes to the position of the bottom dead center, the bolt 29 and the nut 31 are tightened, the lifting bracket 23 is fixed to the support bracket 33, and the secondary battery 15 is It is placed on the upper surface 23 a of the elevating metal fitting 23.

  Next, to hold the secondary battery 15 as shown in FIGS. 2 to 4, the holding metal fittings 19 and 21 are slid along the slit 27 toward the secondary battery 15. Then, when the secondary battery 15 is clamped by the respective pieces 19 b and 21 b, the bolt 29 and the nut 31 are tightened, and the clamp brackets 19 and 21 are fixed to the base body 9. Since the rubber 32 is adhered to the inner surface and the upper surface 23a of the pieces 19b, 21b, the rubber 32 prevents the energization from the secondary battery 15 to the mounting device 3, and the holding force of the rubber 32 by the frictional force increases. The secondary battery 15 can be fixed by absorbing the difference in shape of the secondary battery 15.

  Thus, the position of the two electrodes 77 of the secondary battery 15 is determined by fixing the secondary battery 15 placed on the lifting bracket 23 with the clamps 19 and 21. Therefore, the two first electrode mounting plates 51 are slid in the left-right direction of the movable table 7 along the notch grooves 45 and the first slits 49, and the first electrode mounting plates 51 are disposed on the left and right electrodes 77. .

  Next, the second electrode mounting plate 53 is slid along the second slit 61, and the electrode 55 of the second electrode mounting plate 53 is disposed above the electrode 77. Thereafter, the nut 31 is fastened to the bolt 29, the bolt 59 is fastened to the bolt hole 57, and the first and second electrode mounting plates 51 and 53 are fixed.

  When the operation bar 75 is moved from the position of FIGS. 1 and 2 to the front of the base 1 as shown in FIGS. 11 and 12, the links 69 and 71 overlap with each other in response to the operation of the operation bar 75. The mobile platform 7 moves up until it stands upright. As the link 71 inclines forward of the mount device 3 in conjunction with the operation of the operation bar 75, the moving base 7 moves downward, and the stopper 71 provided on the side frames 41a, 41c is moved to the link 71. The moving table 7 is stopped at the position where it abuts, and the electrode 55 is connected to the electrode 77. Further, since the circular motion of the operation bar 75 is converted into a translational motion along the slider 5 by the toggle mechanism T, the contact speed becomes slow when the electrodes 55 and 77 are in contact with each other, and the electrodes 55 and 77 collide with each other. can avoid.

  Thereafter, the cord from the charge / discharge test apparatus is connected to the electrode 55, whereby the charge / discharge test of the secondary battery 15 becomes possible.

  FIG. 14 shows a state in which the secondary battery 15-1 of another type is fixed by the clamps 19 and 21 using the mounting device 3 of FIG. The secondary battery 15-1 is different in shape and width from the secondary battery 15 shown in FIG. 3, and the outer shape is formed in a cylindrical shape, and two electrodes 77-1 are provided on the upper surface. Note that, according to the procedure described above, the secondary battery 15-1 is fixed on the base 1 as shown in FIG. 14 by adjusting the height of the elevating bracket 23 and positioning the clamping brackets 19 and 21, as will be described later. It is assumed that the electrode 77-1 is disposed along the front-rear direction of the base 1.

  As described above with reference to FIGS. 9 and 10, the second electrode mounting plate 53 can be attached to and detached from the first electrode mounting plate 51 using the opening 63 of the first electrode mounting plate 51. Further, by removing the side frame 41 d from the frame body 41, the electrode mounting plate 47 can be attached to and detached from the movable table 7.

  Therefore, according to the arrangement direction of the electrodes 77-1 as shown in FIG. 14, the side frame 41d is first removed from the frame body 41 and the one electrode mounting plate 47 is removed from the mounting device 3 of FIG. Then, a set of two second electrode attachment plates 53 are additionally attached to the remaining electrode attachment plate 47. The second electrode mounting plate 53 is mounted after the upper and lower second electrode mounting plates 53 to which the electrode 55 is attached are passed through the opening 63 and the second electrode mounting plate 53 is rotated by 90 °, and then the slits 61, The bolt 29 may be passed through the bolt insertion hole 65 and the nut 31 may be screwed onto the shaft portion 29a from the back side.

  As described above, after the first electrode mounting plate 51 and the second electrode mounting plate 53 are exchanged from the mounting device 3 of FIG. 1 as shown in FIG. 14, the height of the elevating metal fitting 23 is adjusted according to the procedure described above. As described above, since the bottom dead center of the position of the electrode 55 is determined in advance by the toggle mechanism T, the lifting bracket 23 is slid so that the electrode 77-1 of the secondary battery 15-1 comes to the bottom dead center. It is moved up and down along 35. Then, at the position where the electrode 77-1 of the secondary battery 15-1 comes to the bottom dead center, the bolt 29 and the nut 31 are tightened, and the lifting bracket 23 is fixed to the support bracket 33, so that the secondary battery is fixed. 15-1 is placed on the upper surface 23 a of the lifting bracket 23.

  Next, in order to clamp the secondary battery 15-1, the clamps 19 and 21 are slid along the slit 27 toward the secondary battery 15-1. Then, at the place where the secondary battery 15-1 is clamped by the respective pieces 19 b and 21 b, the bolt 29 and the nut 31 are tightened, and the clamp brackets 19 and 21 are fixed to the base body 9. Since the rubber 32 is adhered to the inner surface and the upper surface 23a of the pieces 19b and 21b, the rubber 32 prevents the energization from the secondary battery 15-1 to the mounting device 3, and the holding force of the rubber 32 by the frictional force is increased. As a result, the secondary battery 15-1 can be fixed by absorbing the difference in the shape of the secondary battery 15-1. In this way, the secondary battery 15-1 is fixed by the clamps 19 and 21, and the two electrodes 77-1 of the secondary battery 15-1 are arranged in the front-rear direction of the base 1.

  Therefore, one first electrode mounting plate 51 is slid directly above the secondary battery 15-1 along the notch groove 45 and the first slit 49, and the two second electrode mounting plates 53 are second slits. Each electrode 55 is slid along 61 and the two electrodes 77-1 of the secondary battery 15-1 are aligned. Then, the nut 31 is fastened to the bolt 29 and the bolt 59 is fastened to the bolt hole 57.

  Thereafter, if the operation bar 75 is moved to the front of the base 1 from the position shown in FIG. 14, the movable stand is moved until the links 69, 71 overlap with each other to be erected upward in conjunction with the operation of the operation bar 75. 7 rises. Then, as the link 71 inclines forward of the mount device 3, the moving table 7 moves downward, and the moving table 7 stops when the link 71 contacts the stopper 79 of the side frames 41a and 41c. Electrode 55 and electrode 77-1 are connected. Since the circular motion of the operation bar 75 is converted into a translational motion along the slider 5 by the toggle mechanism T, the contact speed becomes slow when the electrodes 55 and 77-1 are in contact with each other, and the electrodes 55 and 77-1 Collisions between each other can be avoided.

  Thereafter, the cord from the charge / discharge test apparatus is connected to the electrode 55, whereby the charge / discharge test of the secondary battery 15-1 becomes possible.

  Further, instead of the embodiment described above, when an electrode different from the electrode 55 is required depending on the type of the secondary battery, the second electrode mounting plate 53 to which a different electrode (not shown) is attached can be replaced. Compatible with various types of secondary batteries.

  As described above, according to the mounting device 3, since the electrode 55 can be slid in the front-rear direction and the left-right direction of the base 1, the electrode 55 can be aligned with the position of the electrode of the secondary battery fixed to the base 1. In addition, various secondary batteries can be mounted.

  In addition, since the holding metal fittings 19 and 21 for holding the secondary battery can be slid in the front-rear direction of the base 1 and the height of the elevating metal fitting 23 can be adjusted in the vertical direction of the base 1, the width, thickness, height Secondary batteries with different can be mounted.

  Further, since the second electrode mounting plate 53 can be attached to and detached from the first electrode mounting plate 51, the replacement work of the damaged electrode 55 becomes easier than before, and the electrode is adapted to the shape and material of the secondary battery. It is also possible to change the type.

  In addition, in the conventional mounting device, a mechanism using a spring is employed as a method of applying pressure to the electrodes in order to reduce contact thermal resistance, but the electrodes wear due to the collision of the electrodes with the spring force. It was severe and frequent inspection was necessary.

  Therefore, as described above, in the present embodiment, the toggle mechanism T composed of a link and a slider is used as a method of applying pressure to the electrode 77 of the secondary battery and the electrode 55 of the charge / discharge test apparatus to bring them into close contact with each other. As a result, the contact pressure of the electrodes 55 and 77 is amplified and the moving speed of the electrode 55 is slowed, and the contact thermal resistance and collision energy between the electrodes 55 and 77 can be reduced as compared with the conventional case.

  The above detailed description will clarify the features and advantages of the embodiments. This is intended to cover the features and advantages of the embodiments described above without departing from the spirit and scope of the claims. Any person having ordinary knowledge in the technical field should be able to easily come up with any improvements and changes.
