Description

Technical Field

[0001] The present invention relates to a charge and discharge inspection device capable of simultaneously charging and discharging a plurality of secondary batteries, and in particular to a charge and discharge inspection device and a charge and discharge inspection method capable of adapting to the size errors, shape changes during charging and discharging, and different thickness types of secondary batteries of each secondary battery. Background Art

[0002] In the charge and discharge inspection of secondary batteries, a charge and discharge inspection device is known that can charge and discharge multiple secondary batteries at the same time. However, the secondary batteries that are the objects of charge and discharge have different thicknesses in their characteristics, making it difficult to make the charge and discharge contacts reliably contact. Moreover, when multiple secondary batteries are arranged in the thickness direction, it is even more difficult to make the charge and discharge contacts contact.

[0003] Therefore, there is a demand for a charge and discharge inspection device that can reliably contact the secondary battery and the charge and discharge contacts even when a plurality of secondary batteries are arranged in the thickness direction. As such a charge and discharge inspection device (charge and discharge device), there is a charge and discharge device described in Patent Document 1, for example.

[0004] Patent document 1 describes a charging and discharging device that arranges a plurality of secondary batteries in a stacked manner in the thickness direction (width direction), and performs charging and discharging by bringing charging and discharging contacts (power supply side terminals) into contact with (inserting into) the positive and negative terminals of the secondary batteries.

[0005] The charging and discharging device has a plurality of charging and discharging units, each of which has charging and discharging contacts (power supply side terminals) relative to a plurality of secondary batteries, for each combination of one or more secondary batteries forming a group, and the charging and discharging units are installed in a manner that allows them to slide along the arrangement direction of the secondary batteries.

[0009] Technical Problems to be Solved by the Present Invention

[0010] As mentioned above, since the secondary batteries to be charged and discharged have different thickness characteristics, when multiple secondary batteries are arranged in the thickness direction, if the number is large, the thickness deviation (error) will accumulate. For example, even if the thickness deviation of each secondary battery is only about 0.2 mm, when multiple secondary batteries are arranged in the thickness direction, the deviation will accumulate, and the contact between the terminal and the charge and discharge contact of the secondary battery located far from the reference position will become difficult.

[0011] Thus, since the charging and discharging device described in Patent Document 1 is a mechanism that slides the charging and discharging contacts (power supply side terminals 24) using only the tapered surface 35c of the gasket 35 (Patent Document 1 Figure 1 , 3 ), so the sliding amount of the charge and discharge contact (power supply side terminal 24), that is, the difference in thickness of the secondary battery or the number of the secondary battery that can be handled is determined only by the tapered surface 35c of the gasket 35. Therefore, in order to handle the accumulated large deviation, the gasket must have a certain thickness, and as a result, the size of the tray that receives the secondary battery and the charge and discharge device itself will increase.

[0012] Therefore, the present invention provides a charge and discharge inspection device and a charge and discharge inspection method that can suppress the increase in size of a tray and the device itself, and can ensure that secondary batteries and charge and discharge contacts are in reliable contact even when multiple secondary batteries are arranged in the thickness direction.

[0013] Means for solving technical problems

[0014] The charge and discharge inspection device of the present invention performs charge and discharge by making the charge and discharge contacts contact with the positive terminals and negative terminals of multiple secondary batteries arranged along the thickness direction, respectively. The charge and discharge inspection device has a first movable mechanism and a second movable mechanism. The first movable mechanism makes the multiple charge and discharge units with the charge and discharge contacts move (slide) synchronously along the direction in which the multiple secondary batteries are arranged; the second movable mechanism is independently arranged from the first movable mechanism, and makes the multiple charge and discharge units move (slide) along the direction in which the multiple secondary batteries are arranged.

[0015] Thus, through the first movable mechanism, a plurality of charge and discharge units are synchronously moved (slid) along the direction in which the secondary batteries are arranged, and the spacing between the charge and discharge units is opened or closed according to the thickness of the secondary batteries to be inspected. In addition, through the second movable mechanism, each charge and discharge unit is separately moved (slid) along the direction in which the secondary batteries are arranged, and the charge and discharge units are moved (slid) according to the thickness of each secondary battery to be inspected.

[0016] In addition, it is preferable that the charge and discharge inspection device includes a first profiling tooth for positioning the plurality of charge and discharge units relative to the plurality of secondary batteries by the first movable mechanism.

[0017] By providing the first contour teeth, the plurality of charge and discharge units that are synchronously moved by the first movable mechanism can be easily positioned with a simple structure.

[0018] In addition, preferably, the charge and discharge inspection device is provided with a plurality of second profiling teeth, and the plurality of second profiling teeth are used to position the plurality of charge and discharge units relative to the plurality of secondary batteries respectively through the second movable mechanism.

[0019] By providing a plurality of second contour teeth, each of the charge and discharge units that are moved individually by the second movable mechanism can be easily positioned with a simple structure.

[0020] In addition, the charge and discharge inspection method of the present invention performs charge and discharge by making the charge and discharge contacts contact with the positive terminal and the negative terminal of multiple secondary batteries arranged along the thickness direction, and has the following steps: using a first movable mechanism to synchronously move multiple charge and discharge units with charge and discharge contacts along the direction in which the multiple secondary batteries are arranged; using a second movable mechanism independently of the first movable mechanism to respectively move the multiple charge and discharge units along the direction in which the multiple secondary batteries are arranged.

[0021] Effects of the Invention

[0022] According to this structure, the charge and discharge inspection device of the present invention uses the first movable mechanism to make multiple charge and discharge units move (slide) synchronously along the direction of the secondary battery arrangement, and the spacing between the charge and discharge units is opened or closed according to the thickness of the secondary battery to be inspected. Therefore, even when inspecting various secondary batteries with different thicknesses, multiple charge and discharge units can be moved (slide) synchronously according to the thickness of the secondary battery to be inspected. In addition, through the second movable mechanism, each charge and discharge unit moves (slides) along the direction of the secondary battery arrangement, and the charge and discharge unit moves (slides) according to the thickness of each secondary battery to be inspected. Therefore, even if it is the same type of secondary battery (secondary battery with the same reference thickness), but the thickness is different due to size error or shape change during charging and discharging, the thickness deviation can be absorbed by each secondary battery.

[0023] In addition, the charge and discharge inspection device can easily position the charge and discharge unit with a simple structure by providing the first profiling teeth and the second profiling teeth.

[0024] Furthermore, according to the charge and discharge inspection method of the present invention, it is possible to achieve the same operational effects as those of the charge and discharge inspection device of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Hereinafter, an embodiment of the present invention will be described in detail. However, the description of the components described below is an example (a representative example) of the embodiment of the present invention, and the present invention is not limited to the following contents unless the gist of the present invention is changed.

[0034] [Charge and discharge inspection device]

[0035] Figure 1 , Figure 2 1 is a schematic diagram showing a charge and discharge inspection device according to an embodiment of the present invention. Specifically, Figure 1 is a side view showing the charge and discharge inspection device according to the present embodiment during charging, Figure 2 is the main view. That is, Figure 2 This is a diagram in which the charge and discharge jig 1 is viewed with the vertical plate 14 facing the front.

[0036] The charge and discharge inspection device 100 performs charge and discharge by bringing a plurality of charge and discharge contacts P into contact with the positive and negative terminals of a plurality of secondary batteries B arranged in a row in the thickness direction (width direction).

[0037] In addition, the charge and discharge inspection device 100 is generally composed of a charge and discharge fixture 1 and a secondary battery side fixture 2, wherein the charge and discharge fixture 1 has a charge and discharge contact P and moves up and down through a movable mechanism (not shown); the secondary battery side fixture 2 includes a tray 51 on which a plurality of secondary batteries B are arranged, a partition 42, etc. In this embodiment, four secondary batteries B (Ba~Bd) are arranged in the tray 51 along the thickness direction. In addition, Figure 1 In the example shown, the thickness of each of the four secondary batteries B (Ba to Bd) is W.

[0038] The charge and discharge jig 1 has a plurality of charge and discharge contacts P (Pa to Pd) that are in contact with the positive and negative terminals of the four secondary batteries B (Ba to Bd), respectively. Figure 2 As shown, the charge and discharge contact Pa includes a terminal that contacts the positive terminal of the secondary battery Ba and a terminal that contacts the negative terminal of the secondary battery Ba. The same is true for the charge and discharge contacts Pb to Pd.

[0039] In addition, the charging and discharging fixture 1 has a first movable mechanism 10 and a second movable mechanism 20, wherein the first movable mechanism 10 enables multiple charging and discharging units U having multiple charging and discharging contacts P to move synchronously along the direction (horizontal direction) in which multiple secondary batteries B are arranged; the second movable mechanism 20 is independently arranged from the first movable mechanism 10, so that the multiple charging and discharging units U having multiple charging and discharging contacts P are moved respectively along the direction in which multiple secondary batteries B are arranged.

[0040] [First movable mechanism]

[0041] The first movable mechanism 10 includes a vertical plate 14 , a first contouring tooth 31 , a first mechanism portion 11 provided between the vertical plate 14 and the first contouring tooth 31 , a support plate 12 , and a support rod 13 .

[0042] In this embodiment, the first mechanism part 11 uses a link mechanism. Specifically, the vertical plate 14 and the support plate 12a are connected by the first mechanism part 11a. Similarly, the support plate 12a and the support plate 12b are connected by the first mechanism part 11b, the support plate 12b and the support plate 12c are connected by the first mechanism part 11c, and the support plate 12c and the support plate 12d are connected by the first mechanism part 11d.

[0043] In addition, the support plate 12d and the first profiling tooth 31 are connected by the support rod 13. The charging and discharging jig 1 moves up and down by the movable mechanism (not shown), so the first profiling tooth 31 also moves up and down. In addition, as described later, the first profiling tooth 31 moves in the horizontal direction by the first mechanism part 11. On the other hand, the vertical plate 14 moves up and down, but does not move in the horizontal direction.

[0044] [Second movable mechanism]

[0045] The second movable mechanism 20 has a holding plate 22 connected to the support plate 12 via a second mechanism portion 21. The holding plate 22 is slidably disposed on a support rod 24, wherein the support rod 24 is disposed between the longitudinal plate 14 and the first contour tooth 31. Figure 1 Observe that two support rods 24 are provided near the front side and the inner side (refer to Figure 2 ).

[0046] In addition, if Figure 1 , Figure 2 As shown, a terminal block 23 is fixed to the holding plate 22, and a charge and discharge contact P and a second profile tooth 32 are provided on the terminal block 23. In this specification, a unit having the holding plate 22, the terminal block 23, the charge and discharge contact P and the second profile tooth 32 is referred to as a charge and discharge unit U.

[0047] In the present embodiment, each holding plate 22 ( 22 a to 22 d ) of the second movable mechanism 20 is connected to the support plate 12 ( 12 a to 12 d ) via the second mechanism portion 21 ( 21 a to 21 d ).

[0048] Furthermore, a terminal block 23 (23a to 23d) is fixed to each holding plate 22 (22a to 22d), and a charge and discharge contact P (Pa to Pd) and a second contoured tooth 32 (32a to 32d) are provided on each terminal block 23 (23a to 23d). Figure 2 As shown, the second contour teeth 32 are provided on the charge and discharge contact Pa side that contacts the positive terminal of the secondary battery B and the charge and discharge contact Pa side that contacts the negative terminal of the secondary battery B, respectively.

[0049] The second mechanism 21 can use a spring (coil spring) or other elastic member. The holding plate 22 is slidably provided on the support rod 24 and is connected to the support plate 12 via the second mechanism 21. Figure 6 To explain, when the charge-discharge jig 1 is lowered, the second profiling tooth 32 (32d) contacts the separator 42 (42d) and is moved to the right ( Figure 6 When the second mechanism portion 21 (21d) is pulled (in the direction of the right arrow), the second mechanism portion 21 (21d) is extended, and the charge and discharge unit Ud having the charge and discharge contact Pd moves to the right, that is, to the position where the secondary battery Bd is located.

[0050] On the contrary, when the charge and discharge jig 1 is raised and the contact between the second contour teeth 32 and the spacer 42 is released, the second mechanism portion 21 (spring) contracts and the holding plate 22 returns to the original position.

[0051] [Secondary battery]

[0052] As described above, the four secondary batteries B (Ba to Bd) are arranged side by side in the thickness direction in the tray 51. In addition, the separators 42 are provided between the secondary batteries B.

[0053] In this embodiment, a partition 42a is provided between the tray 51 and the secondary battery Ba, a partition 42b is provided between the secondary battery Ba and the secondary battery Bb, a partition 42c is provided between the secondary battery Bb and the secondary battery Bc, and a partition 42d is provided between the secondary battery Bc and the secondary battery Bd.

[0054] The partition 42 is used to receive the profiling tooth 32 of the charge and discharge inspection device 100. In this embodiment, the partition 42a receives the profiling tooth 32a, the partition 42b receives the profiling tooth 32b, the partition 42c receives the profiling tooth 32c, and the partition 42d receives the profiling tooth 32d.

[0055] In addition, a profiling tooth receiving portion 41 for receiving the profiling tooth 31 is provided on the secondary battery side. The profiling tooth receiving portion 41 has a roller 41R, and the profiling tooth 31 is received by bringing the tip 31T of the profiling tooth 31 into contact with the roller 41R. The shape of the roller 41R is not particularly limited, and any shape may be used as long as it can receive the profiling tooth 31. For example, Figure 1 The shape of the partition 42 shown.

[0056] [Operation of the first movable mechanism]

[0057] Figure 3 Yes means Figure 1 FIG. 1 is a diagram showing a state in which the first movable mechanism of the charge and discharge inspection device is in motion.

[0058] When the charge and discharge fixture 1 (the first profiling tooth 31) is Figure 1 When the state shown is lowered, the tip 31T of the profiling tooth 31 contacts the roller 41R of the profiling tooth receiving portion 41, thereby the first profiling tooth 31 extends in the direction of the first mechanism portion 11 ( Figure 3 right arrow direction) action.

[0059] As a result, the first mechanism portion 11 connected by the support rod 13 is extended and the support plates 12 (12a~12d) are opened, and the charge and discharge unit U having the retaining plates 22 (22a~22d) respectively connected to the support plates 12 (12a~12d), the charge and discharge contacts P (Pa~Pd), etc., respectively moves to the position where the secondary batteries B (Ba~Bd) in contact with the charge and discharge contacts P are located.

[0060] Then, when the first contoured teeth 31 further descend, the charge and discharge contacts P (Pa to Pd) further approach the secondary batteries B (Ba to Bd), and finally the charge and discharge contacts P (Pa to Pd) respectively contact the secondary batteries B (Ba to Bd).

[0061] In addition, a return spring (not shown) is provided in the first mechanism portion 11 (link mechanism). Therefore, when the contact between the secondary battery B and the charge and discharge contact P is released, the charge and discharge jig 1 (first contoured tooth 31) moves from Figure 3 The state shown in FIG. 1 is raised and the contact with the contoured tooth receiving portion 41 is released, and the charge and discharge contact P is pulled by the return spring and returns to the original position ( Figure 1 shown in the position).

[0062] [Operation of the second movable mechanism]

[0063] Figure 4 It is a schematic diagram showing the configuration of a charge and discharge inspection device according to an embodiment of the present invention.

[0064] Figure 4 The structure of the charge and discharge inspection device 100 shown in FIG. Figure 1 Since the charge and discharge inspection device 100 shown is the same, the same reference numerals are used and detailed description thereof is omitted.

[0065] On the other hand, Figure 4 In the example shown, the thickness of the secondary batteries B arranged in the tray 51 is different between the secondary batteries Ba and Bd and the secondary batteries Bb and Bc. The thickness of the secondary batteries Bb and Bc is W2, which is thicker than the thickness W of the secondary batteries Ba and Bd.

[0066] Therefore, with Figure 1 Compared with the secondary battery B shown in FIG. 1 , the deviation accumulates, and the connection between the charge and discharge contact Pd located away from the reference position (vertical plate 14) and the secondary battery Bd becomes difficult. For example, if "W2 = W + α", then Figure 1 Compared with the example shown, the charge and discharge contact Pd (charge and discharge unit Ud) must be moved further toward the position where the secondary battery Bd is located by an amount corresponding to "2α".

[0067] Figure 5 Yes means Figure 4 FIG. 1 is a diagram showing a state in which the first movable mechanism of the charge and discharge inspection device is active. Figure 6 Yes means Figure 4 FIG. 1 is a diagram showing a state in which the first movable mechanism and the second movable mechanism of the charge and discharge inspection device are movable.

[0068] When the first profiling tooth 31 is Figure 4 When the state shown in the figure moves in the vertical direction, the top end 31T of the profiling tooth 31 contacts the roller 41R of the second profiling tooth receiving portion 41, and the first profiling tooth 31 extends in the direction of the first mechanism portion 11 ( Figure 5 right arrow direction) on the left.

[0069] As a result, the first mechanism portion 11 connected by the support rod 13 is extended and the support plates 12 (12a to 12d) are opened, and the retaining plates 22 (22a to 22d) and the charge and discharge contacts P (Pa to Pd) connected to the support plates 12 (12a to 12d) are moved to the position where the secondary batteries B (Ba to Bd) in contact with them are located. Figure 5 As shown, the charge and discharge contact point Pd must move further by an amount corresponding to "2α" to reach the position where the secondary battery Bd is located.

[0070] Here, when the first profiling tooth 31 is Figure 5 When the state shown in the figure is further lowered, the second profiling tooth 32d contacts the gasket 42d, and the second mechanism portion 21d moves horizontally relative to the support plate 12d (refer to Figure 6 Then, the charge and discharge unit Ud including the holding plate 22d connected to the support plate 12d via the second mechanism portion 21d, the charge and discharge contact Pd, etc., moves to a position where the secondary battery Bd is in contact therewith.

[0071] In this way, even if the thicknesses of the plurality of secondary batteries vary and the variations are accumulated when arranged to form a large comb-teeth shape, the charge and discharge inspection device 100 can absorb the variations in thickness using the second movable mechanism 20 .

[0072] In addition, in this embodiment, four secondary batteries B are used to illustrate the deviation, but when the number of secondary batteries B increases, the deviation will naturally increase. In this way, in order to cope with the large deviation, the size (thickness) of the partition (profile tooth receiving portion) must be increased, thereby increasing the size of the tray and the device itself. However, according to the charge and discharge inspection device 100 of the present invention, the deviation of the thickness of the secondary battery B can be absorbed by multiple movable mechanisms such as the first movable mechanism 10 and the second movable mechanism 20, so that such enlargement can be prevented.

[0073] Furthermore, the second movable mechanism 20 is provided independently of the first movable mechanism 10 and is capable of moving the plurality of charge and discharge contacts P (the plurality of charge and discharge units U) separately. Therefore, even when the thicknesses of the plurality of secondary batteries B are all inconsistent or when the secondary batteries swell separately during the charge and discharge inspection, the thickness deviations of the respective secondary batteries B can be absorbed separately.

[0074] [Another embodiment]

[0075] Figure 7 , 8 It is a schematic configuration diagram showing a charge and discharge inspection device according to another embodiment of the present invention.

[0076] like Figure 7As shown, in addition to the structure of the charge and discharge inspection device 100 , the charge and discharge inspection device 200 further includes a cylinder 52 for pressurizing the secondary batteries B arranged in a row in the tray 51 .

[0077] In addition, the charge and discharge inspection device 200 can move the roller 41R of the profile tooth receiving portion 41 up and down (in the vertical direction) by a movable mechanism (not shown). Figures 1 to 6 In the example shown, the charging and discharging jig 1 is lowered so that the tip 31T of the first profiling tooth 31 contacts the roller 41R, but Figure 7 In the illustrated example, the roller 41R can be moved in the vertical direction so that the tip 31T of the first contour tooth 31 can come into contact with the roller 41R.

[0078] In this way, as a structure for moving the plurality of charge and discharge contacts P (a plurality of charge and discharge units U) to the position where the secondary battery B is located, it is also possible to adopt Figure 7 The structure shown.

[0079] In addition, if Figure 8 As shown, in addition to the structure of the charge and discharge inspection device 100, the charge and discharge inspection device 300 has a linear motion mechanism 53, which allows the first movable mechanism 10 to move along the direction in which the plurality of secondary batteries B are arranged ( Figure 8 The linear motion mechanism 53 is controlled by moving in the direction of the arrow (in the direction of the arrow). The linear motion mechanism 53 is composed of, for example, a servo motor and a ball screw. Of course, the linear motion mechanism 53 can be a structure other than the aforementioned structure (servo motor and ball screw), and the first movable mechanism 10 can also be moved manually.

[0080] in addition, Figure 8 The type of secondary battery B in the example shown is Figure 1 The types of secondary batteries B in the examples shown are different. Figure 1 The secondary battery B and Figure 8 As can be seen from the comparison of the secondary battery B shown, Figure 8 The thickness of the secondary batteries B (Ba to Bd) in the example shown is W3, which is Figure 1 The secondary battery B of the illustrated example is a thin type secondary battery.

[0081] In this way, when the secondary battery B being inspected changes, the thickness of the secondary battery B also changes significantly. Therefore, the first movable mechanism 10 can be moved by the linear motion mechanism 53 to change the spacing between the charging and discharging units U from the baseline thickness of the secondary battery B before the change (for example, W) to the baseline thickness of the secondary battery B after the change (for example, W3).

[0082] In addition, when the thickness error becomes large due to the accumulation of deviations of the arranged secondary batteries B, after the first movable mechanism 10 is moved by the linear motion mechanism 53, the first profiling teeth 31 (at Figure 8 On the other hand, since there is a case where the thickness error is small, the charge and discharge inspection device 300 can also adopt a structure in which the first profiling teeth 31 are not provided.

[0083] In addition, the structure of the charge and discharge inspection device 100, 200, 300 in the present embodiment can be appropriately changed within the scope of the main purpose of the present invention. For example, the upper and lower structures of the charge and discharge fixture 1 and the secondary battery side fixture 2 can also be reversed. In this case, the secondary battery side fixture 2 is located at the top, and the charge and discharge fixture 1 is located below it, and the movement is such that the charge and discharge fixture 1 rises toward the secondary battery side fixture 2.

[0084] Industrial availability

[0085] The present invention is a charge and discharge inspection device and a charge and discharge inspection method that can suppress the enlargement of the tray and the device itself, and can ensure reliable contact between the secondary battery and the charge and discharge contacts even when multiple secondary batteries are arranged in the thickness direction. It can be applied in various scenarios and has industrial applicability.
