Description

Charge and discharge device

FIELD OF THE INVENTION The present invention relates to a charge / discharge device capable of following a change in shape of each secondary battery when a plurality of secondary batteries are charged and discharged at one time.

BACKGROUND OF THE INVENTION In recent years, with the development of IT equipment such as smart phones and the practical use of electric vehicles, the demand for secondary batteries such as lithium-ion batteries and nickel-metal hydride batteries is rapidly increasing. In the final step of the mass production process of this secondary battery, the activation and quality inspection of the produced secondary battery is performed, and the charge and discharge test is performed to check whether the specified performance and characteristics are met before shipment.

SUMMARY OF THE INVENTION Problems to be Solved by the Invention However, in Patent Document 1, by inserting a power source terminal into a positive terminal and a negative terminal of a secondary battery, the positive and negative electrodes are prevented from being displaced due to the expansion of the secondary battery. The amount of deviation between the terminal and the power supply side terminal to maintain the connection between the positive and negative terminals and the power supply side terminal. Therefore, the shapes of the positive and negative terminals are limited to those that can be inserted into the power-supply-side terminals, and there is a problem that the versatility is lacking. Furthermore, in Patent Document 1, the position of the positive and negative terminals caused by the expansion of the secondary battery is pulled and the power-supply-side terminals are pulled, so that the charge / discharge unit slides in the arrangement direction of the secondary battery. Therefore, even if the deviation between the positive and negative terminals and the power-side terminal is only a little, it is still easy to apply a load to the power-side terminal. Through repeated charging and discharging, the load is repeatedly increased, and the power-side terminal is suspected of being deformed or damaged, and lacks durability. Problem. Furthermore, in Patent Document 1, it is described that a plurality of secondary batteries are sandwiched one by one in the width direction by a spacer, the imitation teeth formed on the charge-discharge unit are placed between the spacers for positioning, and the power supply side terminals are positioned. Insert the positive and negative terminals. That is, by using one to a plurality of secondary batteries as a group and arranging imitation teeth at the center of one group of secondary batteries, and moving distances of other secondary batteries to the center of the secondary battery as positive and negative electrodes The amount of deviation between the terminal and the power supply side terminal. That is, with the existence of imitation teeth serving as a reference for the amount of deviation in each group of secondary batteries, the deviation amount is not accumulated (accumulated) even in the case where the array of secondary batteries is arranged, and the amount of deviation can be suppressed. However, even if there is only a slight position deviation in each group, the terminals on the power supply side will still be deflected, which may cause deformation or damage due to repeated use. In addition, the number of parts is increased in order to form the imitation teeth, and the structure becomes complicated. In order to allow the imitation teeth to smoothly enter between the spacers, the tip of the imitation teeth is inclined, or a tapered surface is formed on the upper part of the spacer. It is necessary to work on the shape, and it is more laborious to process, and it has the problem of lack of mass productivity.
The present invention has been made in view of this situation, and an object of the present invention is to provide a simple structure that can reliably move a contact probe following the expansion and contraction of a secondary battery during charging and discharging, without applying a load to the contact probe. A charge-discharge device with excellent mass productivity, low cost, and durability that maintains the electrical connection between the positive and negative terminals of the secondary battery and the contact probe in a stable manner.

The details of the charge and discharge device 10 will be described below. In addition, the left-right direction of FIG. 1 is taken as the front-back direction (long side direction) of the charge-discharge device 10, and the up-down direction of FIG. 3 is taken as the left-right direction (width direction) of the charge-discharge device 10.
First, as shown in FIG. 1, the tray unit 12 includes a base portion 17 and a plate-shaped fixed end portion 18 erected on one side (left side in FIG. 1) of the base portion 17 in the longitudinal direction. Further, a spacer 19 that is arranged alternately with the secondary battery 11 and can slide with the secondary battery 11 on the long side direction of the base portion 17 is held on the base portion 17.

The battery 11 and the separator 19 are pressed toward the fixed end portion 18 side. At this time, since the secondary battery 11 and the separator 19 have the same shape, the positive electrode terminals 13 and the negative electrode terminals 14 are arranged at equal intervals. In addition, both sides of the fixed end portion 18 and the pressurized end portion 23 are connected by a connecting member 28, and thereby the movement of the secondary battery 11 and the separator 19 can be guided. In this embodiment, although the fixed end portion 18 and the pressing portion 21 are in direct contact with the secondary battery 11 at both ends, respectively, the fixed end portion 18 and the pressing portion 21 and the secondary battery 11 may be spaced between them. Pieces. Further, handles 29 are attached to the outer sides of the fixed end portion 18 and the pressurized end portion 23 respectively, and the tray unit 12 can be easily carried.

Next, as shown in FIG. 2 and FIG. 3, the contact unit 16 has a guide portion 31 composed of two guide shafts 30 arranged in parallel with the longitudinal direction of the base portion 17. The probe mounting portion 32 penetrates, and the plurality of probe mounting portions 32 are slidably held on the guide portion 31. Two contact probes 15 are mounted on each probe mounting portion 32 at positions corresponding to the positive terminal 13 and the negative terminal 14 of the secondary battery 11. Furthermore, as shown in FIG. 1, both ends of each guide shaft 30 are supported by a fixed support portion 33 on one side and a guide support portion 34 on the other side as a reference for positioning the contact probes 15. Further, as shown in FIG. 1, the contact unit 16 includes a link mechanism 35, one end of which is fixed to the fixed support portion 33, and is connected to the probe mounting portions 32 arranged in an array, and each probe mounting portion 32 is evenly held on one side. The interval is stretched on one side.

The link mechanisms 35 are provided on both sides in the width direction of the contact unit 16 (charge / discharge device 10). Each link mechanism 35 is such that the central portion in the longitudinal direction of each link shaft 37 is held by the central joint portion 38 in a freely rotating manner. The end portions of the adjacent link shafts 37 are connected to the outside of each of the probe mounting portions 32 so as to be freely rotated by the end joint portions 39. Furthermore, one end (on the left side in FIG. 1) of the probe shaft mounting portion 32 (the left end in FIG. 1) that is closest to the fixed end portion 18 (the fixed support portion 33) is freely rotatably held. Is connected to the fixed support portion 33 through the fixed-side link shaft 40. One side of the fixed-side link shaft 40 is rotatably held on the outside of the fixed support portion 33 by a fixed-side engaging portion 41, and an end portion of the link shaft 37 adjacent to the other side of the fixed-side link shaft 40 is terminated. The joints 39 are connected to rotate freely. Further, the end link shaft 43 connected to the probe mounting portion 32 (the right end in FIG. 1) farthest from the fixed end portion 18 (fixed support portion 33) is such that one end portion is free with the end joint portion 39. The end portion of the adjacent link shaft 37 is rotatably connected, and the other end portion is rotatably held on the outside of the probe mounting portion 32 by the pressure-side engaging portion 44. In addition, each of the central joints 38, the fixed-side joints 41, and the pressurized-side joints 44 are arranged at the same height, and each of the end joints 39 is alternately arranged up and down in front of and behind the central joints 38.

With the above configuration, the link mechanism 35 can expand and contract in a bellows shape using the fixed support portion 33 as a reference, and can expand and reduce the interval between adjacent probe mounting portions 32 at equal intervals.
In addition, between the fixed support portion 33 and the probe mounting portion 32 adjacent to the fixed support portion 33 and between the probe mounting portions 32 adjacent to each other, each of the probe mounting portions 32 is directed toward the guide portion. On the other side (right side in FIG. 1) of the potential compression spring, a compression coil spring 46 is inserted outside each guide shaft 30. Moreover, as shown in FIG. 1 to FIG. 3, in the tray unit 12, the imitation block 47 is protruded toward the upper portion of the pressing portion 21, and is located at the probe mounting portion 32 held at the other end (the right end in FIG. 1) of the guide portion 31. The abutting portion 48 is protruded downward.

In the initial state before the start of charge and discharge, as shown in FIG. 1, the imitation block 47 abuts against the abutment portion 48, and the pressing force pressing the pressing portion 21 of the secondary battery 11 and the spacer 19 is transmitted to the probe mounting portion 32. Each compression coil spring 46 is compressed through the probe mounting portion 32, whereby each contact probe 15 (probe mounting portion 32) can be moved toward one side of the guide portion 31 (side of the fixed support portion 33). At this time, the lengths and elastic constants of the compression coil springs 46 are the same, and the positive electrode terminal 13 and the negative electrode terminal 14 of each secondary battery 11 are aligned with the horizontal position of each contact probe 15. In addition, the contact unit 16 is held above the tray unit 12 by the frame 50 of the charge and discharge device 10, and each positive terminal 13 and each negative electrode can be switched by an up and down mechanism (such as a piston) not shown in the figure. The presence or absence of contact (electrical connection) between the terminal 14 and each contact probe 15.

At the start of charging and discharging, as shown in FIG. 4, the contact unit 16 is lowered, and the tips of the contact probes 15 are pressed against the positive terminals 13 and the negative terminals 14. If each secondary battery 11 expands in the thickness direction during charging, as shown in FIG. 5, each secondary battery 11 and the separator 19 gradually move toward the pressure end portion 23 side (the other side of the base portion 17) (FIG. 5). To the right). Then, the interval between the adjacent positive electrode terminals 13 and the negative electrode terminals 14 is increased, and the compression coil spring 26 a is compressed between the pressing portion 21 and the pressing end portion 23. At this time, since the imitation block 47 moves toward the pressurizing end portion 23 together with the pressing portion 21, the compression coil springs 46 are almost aligned with each other in the horizontal position of each of the positive terminal 13 and each negative terminal 14 and each contact probe 15. The method is uniformly extended, and the contact states of the respective positive terminals 13 and the respective negative terminals 14 and the contact probes 15 are maintained. When each secondary battery 11 contracts in the thickness direction at the time of discharge, it changes from the state of FIG. 5 to the state of FIG. 4 by an operation opposite to that described above. Then, by repeatedly charging and discharging, each secondary battery 11 repeatedly expands and contracts, and in the meantime, changes from the state in FIG. 4 to the state in FIG. 5 and changes from the state in FIG. 5 to the state in FIG. 4 are continuously and repeatedly repeated. Furthermore, even if the secondary battery 11 has a size error, a difference in expansion and contraction, and a difference in the operation of the link mechanism 35 and each compression coil spring 46, the positive terminals 13 and the negative terminals are made. In a situation where the positional relationship between 14 and each contact probe 15 slightly deviates, by making each contact probe 15 large-diameter, the positive terminals 13 and each negative terminal 14 and each contact probe 15 can be maintained. Contact (connected state). At this time, since the tip of each contact probe 15 is only in contact with the surface of each of the positive electrode terminal 13 and each negative electrode terminal 14, no load is applied to each contact probe 15 and it has excellent durability.

In addition, although a pantograph can be used as a link mechanism, in this case, one side of the pantograph must be connected to a fixed support portion, and a dummy block must be fixed (connected) to the other to which the pantograph is connected. The probe mounting portion on the side is formed so that when the dummy block moves back and forth together with the pressing portion, the other side of the scaler moves back and forth. That is, each time the tray unit is replaced, it is necessary to fix (connect) the probe mounting portion and the dummy block (pressing portion) and release it, which is labor-intensive and time-consuming. In the link mechanism 35 of this embodiment, the compression coil spring 46 is externally inserted into each of the guide shafts 30, and the link mechanism 35 is automatically extended by the restoring force of the compression coil spring 46 when the secondary battery 11 expands, so that As described above, the dummy block 47 only needs to be in contact with the abutting portion 48, and there is no need to fix (connect) the dummy block 47 (pressing portion 21) to the probe mounting portion 32. Therefore, the loading and unloading of the tray unit 12 to and from the frame body 50 is easy and the work efficiency is excellent.

Next, a charge / discharge device 51 according to a second embodiment of the present invention will be described. The same components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.
The charging / discharging device 51 shown in FIG. 6 is different from the first embodiment in that the contact unit 52 is not provided with the link mechanism 35. Instead, the positioning recesses 53 are formed at two positions in the width direction of the upper surface of each spacer 19, and Positioning protrusions 54 are attached to the respective probe mounting portions 32 at positions corresponding to the positioning recesses 53. When the contact unit 52 is lowered at the start of charging and discharging, the positioning protrusions 54 are inserted (fitted) into the positioning recesses 53 and the secondary batteries 11 are connected to the probe mounting portions 32. And when each negative electrode terminal 14 moves due to the expansion and contraction of each secondary battery 11 during charge and discharge, each contact probe 15 also moves together with each probe mounting portion 32 to reliably maintain the electrical connection state. In this case, since each of the spacers 19 and each of the probe mounting portions 32 are connected through each of the positioning protrusions 54, no load is applied to each of the contact probes 15, and the durability is excellent.

Although the embodiments of the present invention have been described above, the present invention is not limited to any of the structures described in the above embodiments, and also includes other embodiments or modifications that can be conceived within the scope of matters described in the scope of patent application. In the above-mentioned embodiment, although the situation in which the positive electrode terminal and the negative electrode terminal of the secondary battery are arranged on the upper surface of the secondary battery has been described, even if the arrangement of the positive electrode terminal and the negative electrode terminal of the secondary battery is different, it can still be changed. Corresponds to the arrangement of the contact unit. For example, in a situation where the positive electrode terminal and the negative electrode terminal are arranged on the side surface of the secondary battery, it is only necessary to arrange the contact unit on the side of the secondary battery according to the direction of the positive electrode terminal and the negative electrode terminal.
In addition, the potential energy component only needs to be a thing capable of pressing the secondary battery and the separator toward the fixed end side, and its structure is not limited to the above-mentioned embodiment. For example, the number or arrangement of the pressure shaft and the guide shaft can be appropriately selected. Furthermore, instead of raising and lowering the contact unit side, a structure of raising and lowering the tray unit side may be adopted.
