The present invention relates to a battery tray in which a battery is housed in a battery manufacturing process, and a battery tray in which a plurality of batteries having different thicknesses can be accommodated by using one tray, and the battery tray is used. Battery manufacturing method》

[Prior Art] In the manufacturing process of the battery, there is a step of performing the treatment while the battery is housed in the tray. Further, a tray is also used for the collection and storage between manufacturing processes. In the patent documents 1 and 2 (Patent Document 1: JP-A-2000-53 1 82, and JP-A-2002-362566), it is proposed to realize a battery that can reduce the weight while ensuring the necessary strength. tray. Further, in the step of charging (charging) the battery, in a state in which a plurality of electric cells are housed in the tray, charging is performed in a state where the battery β pole is crimped to the upper and lower terminals of the battery. In this case, it is necessary to ensure reliable charging by ensuring the positional accuracy between the upper and lower terminals of the battery and the electrodes. Fig. 20(a) is a plan view showing an example of a conventional battery tray. This figure shows an example of a tray for a prismatic battery. A plurality of battery storage portions 101 are provided on the square battery tray 100. Fig. 20 (b) is an enlarged view showing one portion of the battery housing portion 101. This figure shows the state after receiving the prismatic battery 102 (hatched portion). Both end portions 103 of the battery housing portion 101 are narrowed in width, and both end portions of the prismatic battery 102 are engaged with the portion. Thereby, the prismatic battery ι〇2 -5 - 1363447 can be stably placed in the battery housing portion 101. Therefore, in the compounding step, the accuracy of the positional relationship between the upper and lower terminals of the prismatic battery 102 and the upper and lower electrodes for charging can be ensured, and charging can be surely completed. [Explanation] - [Problem to be Solved by the Invention] However, as described above, the battery tray 100 shown in FIG. 20 has the width of both end portions 103 of the battery housing portion 101 in conformity with the prismatic battery 102. The design of the thickness. Therefore, special trays must be prepared for each type of square sink with different thicknesses. In this case, the mold for forming the tray is also dedicated to each type of tray, which is disadvantageous in cost. In the manufacturing process, it is necessary to change the corresponding tray according to the thickness of the prismatic battery, which is also disadvantageous in terms of production efficiency. Further, in Patent Documents 1 and 2 described above, no particular arrangement has been proposed for a structure in which a plurality of types of batteries can be accommodated. The present invention has been made to solve the above conventional problems, and an object thereof is to provide a battery tray in which a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray. [Means for Solving the Problem] In order to achieve the above object, a battery tray according to the present invention is a battery tray for accommodating a battery, comprising: an opening; and a housing portion provided on a back side of the opening; The inclined portion inside the accommodating portion is spaced apart from the inclined portion, and the battery is widened toward the opening, and the battery can be surrounded by the opening and abutting the inclined portion -6 - 1363447. In the state, it is accommodated in the storage unit. [Effects of the Invention] According to the present invention, a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray. [Embodiment]

[Embodiment of the Invention] The battery tray of the present invention has an inclined portion that widens with respect to the interval between the facing portions as it goes toward the opening. Therefore, even if the battery has a different thickness or outer diameter, the mounting position can be changed. The height is placed on the groove, and a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray. In the battery tray according to the above aspect of the invention, the battery tray is a battery tray for accommodating a cylindrical battery, and the inclined portion is preferably formed to support the bottom of the cylindrical battery at least three points. This structure is suitable for storage of cylindrical batteries having different outer diameters. Further, the inclined portion includes a groove that faces the inclined surface, and the interval between the opposing inclined surfaces is preferably widened toward the opening. This structure is suitable for storage of prismatic batteries of different thicknesses. Further, when the state of the battery is observed from the side facing the opening, the opening preferably includes a regulating surface for restricting the movement of the battery in the width direction. According to this configuration, since the movement in the width direction of the battery can be restricted, the battery can be stably accommodated in the width direction. 1363447 Further, when the state of the battery is observed from a side facing the opening, the opening is preferably a pair of diagonal positions of the battery, and a regulating surface for restricting the rotational movement of the battery is preferable. According to this configuration, even if the thickness of the accommodated battery is increased, it is possible to maintain a stable upright state in a state in which the amount of increase in thickness is reversed in accordance with the amount of increase in thickness on the side opposite to the restriction surface that restricts the rotational movement. . Further, it is preferable that the restriction surface for restricting the movement in the width direction and the restriction surface for restricting the rotation movement intersect at an obtuse angle. Further, when the battery is placed upright on the groove, the distance between the inclined surface of one of the batteries and the battery is smaller than the distance between the other inclined surface and the battery. In this configuration, it is preferable to reduce the sway during storage of the prismatic battery having a large thickness, and to achieve stable storage. Further, the inner circumferential surface of the opening and the inner circumference of the accommodating portion are provided. It is preferable that the surface system is on the same plane. According to the structure, one of the trays is shaped to become

Further, it is preferable that the opening is formed in a plurality of opening rows, and the respective opening columns are arranged in parallel with each other. Further, it is preferable that the battery tray has a structure in which a first tray in which the groove is formed and a second tray in which the opening is formed are combined. According to this configuration, the configuration of the mold in the case of the resin-molded tray becomes simple. The above second tray can be replaced with a preferred one. According to this configuration, since the first tray is shared while the second tray is replaced with the tray having the changed opening shape, the thickness of the accommodating battery can be increased by <S > -8 - 1363447. Further, it is preferable that the opening has a tapered surface on a side opposite to the storage portion. According to this configuration, storage of the battery becomes easy. Further, a through hole is formed in the inside of the accommodating portion, and a battery that is accommodated in the accommodating portion by an electrode that passes through the through hole and an electrode on the opening side is preferably used. According to this structure, the battery tray can be used in the compounding process.

(Embodiment) Fig. 1 is a view showing a lower tray in a lower battery tray according to an embodiment of the present invention. Figure 1 (a) is a top view and Figure 1 (b) is a side view. A plurality of battery accommodating portions 2 are provided in the lower tray 1, and one rectangular battery can be accommodated in each of the battery accommodating portions 2. FIG. 2 is an enlarged view showing the battery housing portion 2. Fig. 2 (a) is a plan view, and Fig. 2 (b) is a cross-sectional view taken along line A - A of Fig. 2 (a). Although the battery housing portion 2 is disposed obliquely in Fig. 1, it is vertically illustrated in Fig. 2 for easy understanding. Further, the square battery 5 at the time of storage is shown by a two-dot chain line. In Fig. 2(a), the groove 3 as the inclined portion is formed at both end portions in the width direction (arrow direction a direction) of the battery housing portion 2 so as to sandwich the through hole 4. In the present embodiment, the groove 3 is not formed in the formed portion of the through hole 4. Therefore, the groove 3 of Fig. 2(b), in the illustration of Fig. 2(a), shows the groove (S) -9 - 1363447 on the upper side of the groove 3 through the through hole 4.

Further, in the second embodiment, the accommodating portion 21 of the lower tray as shown in Fig. 13 may have a structure in which a through hole is formed in the groove without dividing the groove.

As shown in Fig. 2(b), the groove 3 is formed on the back side (bottom side) of the battery housing portion 2, and the opposing inclined surface 3a and the inclined surface 3b are formed in a V shape. The inclined faces 3a and 3b are formed so that the interval between the inclined surface 3a and the inclined surface 3b becomes wider toward the surface side of the lower tray 1. The bottom surface of the prismatic battery 5 is placed on the groove 3, and the position of the height direction of the prismatic battery 5 (the direction of the arrow mark b) is determined by the groove 3. Further, although the groove 3 is illustrated as a V-shaped example, the bottom portion of the groove 3 where the prismatic battery 5 does not abut may be formed in a curved shape or may include a horizontal surface. Further, a configuration including a curved surface may be considered for the inclined surface on which the prismatic battery 5 abuts. In other words, the cross-sectional shape of the groove 3 is not limited to a completely V-shape, and may include a portion formed by widening the interval between the inclined surface 3a and the inclined surface 3b. A through hole 4 is provided in each of the battery housing portions 2. As shown in Fig. 2(b), the through hole 4 is formed to penetrate the bottom surface of the lower tray 1. In the compounding step, the electrode can be passed through the through hole 4, and the electrode and the other electrode dropped from the upper side are pressed against the upper and lower terminal portions of the prismatic battery 5 to charge the prismatic battery 5. The details of the charging will be specifically described later. Figure 3 is a diagram showing the upper tray. Fig. 3(a) is a plan view, and Fig. 3(b) is a side view. The upper tray 6 has a plurality of openings 7 formed in the flat member. When the lower tray 1 of Fig. 1 and the upper tray 6 of Fig. 3 are combined, -10- 1363447, one portion of the opening 7 corresponds to one of the battery storage portions 2 of the lower tray 1. Fig. 4 is an enlarged view showing the opening 7. Fig. 4(a) is a plan view, and Fig. 4(b) is a cross-sectional view taken along line B-B of Fig. 4(a). In Fig. 3, the opening 7 is arranged obliquely, but is vertically shown in Fig. 4 for easy understanding. Further, the prismatic battery 5 at the time of storage is shown by a two-dot chain line.

As shown in Fig. 4 (b), the opening 7 is formed so as to penetrate the upper tray 6 in the thickness direction. Further, as shown in Fig. 4(a), a portion surrounded by each of the pair of vertical faces 8, 9, the horizontal planes 1 〇, 1 1 and the inclined faces f2, 1-3 becomes a port 7, and the opening 7 is formed in a polygonal shape. . The inclined faces 12, 13 are disposed at a pair of diagonal positions of the opening 7, i.e., at a pair of diagonal positions of the battery 5 after storage. The angle formed by the horizontal plane 10 and the inclined surface 12, the angle formed by the horizontal plane 11 and the inclined surface 13 are respectively obtuse angles. Specifically, these angles are preferably obtuse angles of 1 degree or more and 150 degrees or less, respectively. In the present embodiment, the angle is 120 degrees. The details will be described later. The horizontal planes 11 and 1 1 are limiting surfaces for restricting the movement of the battery in the width direction (arrow direction a). The inclined surfaces 12 and 13 limit the two directions of the battery (arrows c and d) The limit surface of the rotational movement of one of the rotational movements (the direction of the arrow mark d). When the prismatic battery 5 is housed in the battery housing portion 2, the prismatic battery 5 is inserted into the battery housing portion 2 through the opening 7 from the upper side of the opening 7. To facilitate this insertion, a tapered surface 14 is provided on the upper side of the opening 7. As shown in Fig. 4 (a), the prismatic battery 5 is limited by the horizontal plane 1 〇, 1 1 and the inclined surface -11 - 1363447 1 2, 1 3 . Therefore, the tapered surface 14 is provided at least on each of these faces. Fig. 5 is a view showing a state in which the upper tray 6 and the lower tray 1 are combined. Figure 5 (a) is a plan view, and Figure 5 (b) is a side view. As shown in Fig. 5 (b), the upper tray 6 is provided on the upper side of the lower tray 1, and the battery housing portion 2 is provided on the lower side of the opening 7 of the upper tray 6 in the illustration of Fig. 5(a).

Fig. 6(a) is an enlarged view showing a portion of the opening 7 of Fig. 5(a). Fig. 6(b) is a cross-sectional view taken along line C-C of Fig. 6(a). In Fig. 5(a), the opening 7 portion is obliquely arranged, but is vertically illustrated in Fig. 6(a) for easy understanding. Further, the square battery 5 at the time of storage is shown by a two-dot chain line. One portion of one battery housing portion 2 corresponds to one portion of the opening 7. When the prismatic battery 5 is inserted from the upper side of the opening 7, the bottom surface of the prismatic battery 5 abuts against the inclined surfaces 3a and 3b of the groove 3, and the prismatic battery 5 is housed in the battery storage portion in a state surrounded by the opening 7. 2 inside. In the present embodiment, the battery tray is divided into the upper tray 6 and the lower tray 1. According to this configuration, the structure of the mold at the time of resin molding is simplified. Further, the positioning of the upper and lower trays can be performed by fitting a positioning pin (pin) to the positioning hole. When the resin is molded, the positioning pin and the positioning hole may be integrally formed. Next, the compounding process of the battery will be described. Fig. 7 (a) is a plan view showing a state in which the prismatic battery 5 is housed in the battery housing portion 2. Fig. 7 (b) and (c) are cross-sectional views taken along line D - D of Fig. 7 (a), Fig. 7 (b) shows the state before charging, and Fig. 7 (c) shows the state at the time of charging. As shown in Fig. 7 (a -12- 1363447), when the prismatic battery 5 is housed, the prismatic battery 5 is surrounded by the opening 7, and as shown in Fig. 7(b), the prismatic battery 5 is inclined with the groove 3. The state in which the faces 3a and 3b are in contact with each other is accommodated in the accommodating portion 2"

As shown in Fig. 7 (b), in the compounding step, the upper electrode 15 and the lower electrode 16 are provided above and below the prismatic battery 5, respectively. The upper electrode 15 is lowered during charging and moved so as to approach the positive terminal 17 of the prismatic battery 5. The lower electrode 16 is lifted and moved through the through hole 4 to move closer to the negative terminal 18 of the prismatic battery 5. In the state of Fig. 7(c), the upper and lower electrodes 15 and 16 are in contact with the positive electrode terminal 17 and the negative electrode terminal 18, respectively. The lower electrode 16 presses the prismatic battery 5 toward the upper side, and the prismatic battery 5 is raised by the pressing. In this state, the prismatic battery 5 is charged, and the upper and lower electrodes 15, 16 are moved in the opposite direction to the above, and are separated from the prismatic battery 5. Next, the storage of the prismatic batteries 5 having different thicknesses will be specifically described with reference to the examples. The battery tray ' of this embodiment is a prismatic battery 5 which can accommodate a thickness of at least 4 mm to 8 mm. Hereinafter, an example of accommodating the prismatic batteries 5 of four thicknesses of 4 mm, 5 mm, 6 mm, and 8 mm will be described. Fig. 8 is a plan view showing a state in which a rectangular battery 5 having a thickness of 4 mm is housed in the battery housing portion 2. 9(a) is a cross-sectional view taken along line E-E of FIG. 8, and FIG. 9(b) is a cross-sectional view taken along line F-F of FIG. 8. As shown in part A of FIG. 8, one of the square batteries 5 is shown. The end portion is restricted by both the horizontal plane 1 〇 and the inclined surface 12 of the opening 7. The portion C of Fig. 9(a) shows a case where the end portion of the prismatic battery 5 is restricted by the inclined surface 1 2 . As shown in part B of Fig. 8, the other end portion of -13-1363447 of the prismatic battery 5 is defined by the two horizontal surfaces 11 and the inclined surface 13 of the opening 7. The portion D of Fig. 9(b) shows a case where the end portion of the prismatic battery 5 is restricted by the inclined surface 13. As shown in Figs. 9(a) and 9(b), the prismatic battery 5 is placed on the inclined surfaces 3a and 3b of the cross section V-shaped groove 3. In this state, the two ridge lines at the bottom of the square-battery 5 are in line contact with the inclined faces 3a, 3b of the groove 3. The prismatic battery 5' is placed on the groove 3 to determine the position of the height direction (the direction of the arrow mark b), and the bottom of the prismatic battery 5 is located at the center of the bracket. ... — The prismatic battery 5 is kept in an upright state and unstable in the state of being placed on the groove 3. However, as described above, the prismatic battery 5 is located in the opening 7, and the prismatic battery 5 restricts the movement in the direction of the arrow mark e by the inclined surface 12, and restricts the movement in the direction of the arrow mark f by the inclined surface 13 (refer to FIG. 8). ,9). Thereby, the prismatic battery 5 does not fall down and can be kept in an upright state.

Fig. 10 is a plan view showing a state in which a prismatic battery 5a having a thickness of 5 mm is housed in the battery housing portion 2. Fig. 11(a) is a cross-sectional view taken along line g_G of Fig. 10. Fig. 1 1 (b) is a cross-sectional view of the Η-Η line of Fig. 10. The square battery 5a has a thickness t which is increased by 1 mm as compared with the square battery 5 having a thickness of 4 mm, but has the same width. As shown in Fig. 1 1 (a) and (b), the square battery 5a is placed on the groove 3, and the bottom surface of the prismatic battery 5a is located at a height h2 from the bottom surface of the tray. The square battery 5a having a thickness of 5 mm is increased by 1 mm from the thickness t of the prismatic battery 5. Therefore, the height h2 of Figs. 11(a) and (b) is higher than the height hi of Figs. 14 - 1363447 9 (a) and (b). That is, since the groove 3 has a V shape, even a prismatic battery having a different thickness can be placed on the groove 3 by changing the height of the placement position.

As shown in part A of Fig. 10, one end portion of the prismatic battery 5 is restricted by both the horizontal plane 1 〇 and the inclined surface 1 2 of the opening 7. Part C of Fig. 11 (a) shows a case where the end portion of the prismatic battery 5 is restricted by the inclined surface 1 2 . As shown in part B of Fig. 10, the other end portion of the prismatic battery 5 is defined by the horizontal plane 11 of the opening 7 and the double-side restricting position of the inclined surface 13. The portion D of Fig. 1 1 (b) shows a case where the end portion of the prismatic battery 5 is restricted by the inclined surface 13 . These states are the same as those in the case of the prismatic battery 5 having a thickness of 4 mm as explained with reference to Figs. However, the prismatic battery 5a is rotationally moved from the position of Fig. 8 as compared with the prismatic battery 5 due to the increase in thickness. In this case, the drawings of Fig. 10 and Fig. 10 will be specifically described. As shown in Fig. 10, the prismatic battery 5a is placed at a pair of diagonal positions, and the position is restricted by the inclined faces 1 2, 13 respectively. Therefore, the prismatic battery 5a is not rotatable in the direction of the arrow mark d along the inclined faces 12, 13 at both end portions. This is because the distance between the inclined surface 12 located at the diagonal position of the opening 7 and the inclined surface 13 is smaller than the width of the prismatic battery 5a. However, among the both end portions of the prismatic battery 5a, the side opposite to the inclined faces 12, 13 is not restricted by the opening 7. Further, as described above, the prismatic battery 5a is restricted in the width direction (the direction of the arrow mark a) by the horizontal plane 10 and the horizontal plane 1 1 , but the shape of each end portion is a curved shape -15 - 1363447. Therefore, the prismatic battery 5a can be rotationally moved in the direction of the arrow mark c while the both end portions of the prismatic battery 5a move along the horizontal planes i, 11.

Here, it is assumed that the two ridge lines at the bottom of the prismatic battery 5a are placed in contact with the inclined faces 3a and 3b of the groove 3 in a linear contact state. In this state, when the prismatic battery 5a is twisted and rotated in the direction of the arrow symbol c, the two ridge lines at the bottom of the prismatic battery 5a are moved away from the inclined faces 3a and 3b of the groove 3. As a result, the two ridge lines at the bottom of the prismatic battery 5a are in linear contact with the inclined surfaces 3a and 3b, and the two inclined surfaces 3a and 31 are in contact with each other at two points. state. In other words, since the prismatic battery 5a has a larger thickness than the prismatic battery 5, the state of Fig. 8 cannot be maintained. However, as shown in FIG. 1A, only the movement angle Θ1 is rotated in the direction of the arrow mark c, and the abutment state of the bottom of the prismatic battery 5a on the groove 3 is changed from the line contact to the point contact, and can be maintained. Falling steady state. The angle Θ1 is the rotation angle of the center line in the width direction of the prismatic battery. In the present embodiment, Θ1 is 〇.57°. Further, in Fig. 10, for convenience of illustration, the angle Θ1 indicates the angle formed by the vertical line and the side surface of the prismatic battery. This is also the same for the angles Θ2 and Θ3 of Fig. 12. Fig. 12 (a) is a plan view showing a state in which a prismatic battery 5b having a thickness of 6 mm is housed in the battery housing portion 2. Fig. 12 (b) is a plan view showing a state in which the prismatic battery 5c having a thickness of 8 mm is housed in the battery housing portion 2. As described above, the prismatic batteries 5b and 5c having a large thickness are rotatably moved and housed in the accommodating portion 2. The larger the angle, the larger the angle of rotation. In the case of the square battery 5b, Θ2 is 1.78°. In addition, the case of 'square battery 5c

< :S -16- 1363447, 03 is 4.4 7 4°. In other words, according to the battery tray of the present embodiment, a plurality of types of batteries having different thicknesses can be accommodated, and the thickness of the accommodated battery can be increased, and the stored battery can be stably moved in response to an increase in thickness. Upright state.

As described above, the battery tray of the present embodiment has been described as being capable of accommodating a plurality of prismatic batteries having different thicknesses. As described above, when a rectangular battery having an increased thickness is accommodated, the rotation angle of the prismatic battery also increases in response to an increase in thickness. —— However; ±_ lower electrode 15_, - Ϊ6 (Fig. 7) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Therefore, even if the rotation angle is increased, the areas of the abutting portions of the upper and lower electrodes 15, 16 located at the center portion and the respective terminals of the prismatic battery are the same or hardly changed. Therefore, even if the rotational movement is performed, the contact area between the upper and lower electrodes 15 and 16 and the terminals of the prismatic battery can be ensured, and reliable charging can be performed in the compounding step. Further, in the battery tray of the present embodiment, a rectangular battery having a thickness of different ^0 can be accommodated, but the range of the thickness is limited by the shape of the opening of the upper tray. In order to correspond to the thickness of a square battery having a larger range, a plurality of upper trays having different opening shapes may be prepared in advance. In this way, the thickness of the storable prismatic battery can be made into a wide range even if the lower tray is shared and only the upper tray is replaced. Further, in the same manner, in order to correspond to the width dimension of a wide range of prismatic batteries, by using the upper tray having different opening shapes in the width direction, the range of the width of the receivable rectangular battery can be made into a wide range. Furthermore, it is also possible to use an upper tray of a corresponding thickness and a corresponding width. In the battery tray of the present embodiment, the rotation angle of the prismatic battery is zero when the rectangular battery having a thickness of 4 mm is accommodated. However, the present invention is not limited thereto, and may be appropriately determined. Further, the battery tray of the present embodiment has been described as an example used in the compounding step, but the application is not limited thereto. For example, it may be used during the manufacturing process to receive the battery or as a storage battery.

To use. Further, in the battery tray of the present embodiment, as described above, even if the cloud 0 battery having the thickness of the crucible is received, the shape of the opening of the upper tray can maintain the upright state of the prismatic battery, and the electrode and the prismatic battery can be charged during charging. The terminal portion is in contact. On the other hand, when the position of the prismatic battery required for storage is loose, the shape of the opening of the upper tray is not limited to the shape of the present embodiment. For example, it is also conceivable to have a V-shaped groove shape of the lower tray, and the shape of the opening of the upper tray is a shape that narrows the thickness direction of the battery without making an inclined surface. Even with this type of tray, it is possible to store a variety of square batteries of different thicknesses. (Embodiment 2) Hereinafter, Embodiments 2 to 5 will be described with reference to the drawings. In the following description, only portions different from the above-described first embodiment will be described. The other configurations are the same as those of the first embodiment, and therefore the overlapping description will be omitted. Fig. 13 is a plan view showing the lower tray in the lower battery tray in the second embodiment. The shape of the side surface is the same as that of Fig. 1 18-1363447 (b) of the above-described first embodiment, and therefore will be omitted. In Fig. 1, the battery housing portion 2 is disposed obliquely with respect to the outer circumference of the lower tray 1. The battery housing portions 2 are arranged in a row in the oblique direction, and the columns are parallel to each other. On the other hand, in the configuration of FIG. 13 , the rows of the battery storage portions 21 arranged in a line are parallel to each other as in FIG. 1 , but the rows are arranged in parallel with the outer circumference of the lower tray 20 . .

Fig. 14 is a plan view showing the upper tray 22 corresponding to the lower tray 20 of Fig. 13. The shape of the side surface is the same as that of Fig. 3 (b-) of the first embodiment described above, and therefore the description is omitted. An i-tray 22 is the same as the upper tray 6 of Fig. 3 except for the arrangement of the openings. The opening 23 of Fig. 14 is arranged to correspond to the battery housing portion 21 when the upper tray 22 is placed on the lower tray 20 of Fig. 13 . That is, each row of the openings 7 is arranged to be parallel to the side of the outer circumference of the upper tray 22. In the present embodiment, the number of batteries per unit area is reduced as compared with the tray of the first embodiment, but the arrangement of the battery housing portion 21 and the opening 23 is simplified. Therefore, there is a case where the setting of the apparatus for setting the tray, the apparatus for accessing the battery to the tray, and the like are facilitated. In the embodiment, the trays of the first and second embodiments are separated into an upper tray and a lower tray. However, the tray of the third embodiment is formed integrally with the upper and lower trays. Fig. 15 (a) shows a plan view of the portion of the opening 24, Fig. 15 (b) is a sectional view of the line I - I of Fig. 15 (a), and Fig. 15 (c) is a diagram of Fig. 15 (a) A section of the J-J line. -19- 1363447 When the upper and lower trays are integrally formed by the configuration shown in Fig. 6(b), it is difficult to pull out the mold in the accommodating portion 2 from the accommodating portion 2. In the cross-sectional view of Fig. 15 (b), the inner circumferential surface of the opening 24 and the inner circumferential surface of the accommodating portion 25 are on the same plane. Similarly, in the cross-sectional view of Fig. 15(c), the inner circumferential surface of the opening 24 and the inner circumferential surface of the accommodating portion 25 are on the same plane. This structure is easy to pull out the mold from the accommodating portion 25, and it is possible to easily form a tray in which the upper and lower trays are integrated.

This embodiment is easy to form and is effective in limiting the width of the battery to be stored. (Embodiment 4) Fig. 16 is a cross-sectional view showing the tray of the fourth embodiment. This figure is equivalent to Fig. 9(a) of the Ε-Ε line sectional view of Fig. 8. Hereinafter, description will be made in comparison with the embodiment 1. The prismatic battery 5 of Fig. 16 is the same as the prismatic battery 5 of Fig. 9(a). The two ridge lines at the bottom of the prismatic battery 5 are in linear contact with the inclined surfaces 26a and 26b of the groove 26, and the prismatic battery 5 is placed at a position hi from the bottom surface height of the tray. The mounted state is the same as that of the first embodiment. 9 (a) The square battery 5 is the same. The configuration of Fig. 16 differs from the configuration of Fig. 9(a) in that the inclination angles of the inclined faces 26a and 26b are different. In Fig. 16, the inclined faces 26a, 26b are disposed such that the distance between the inclined face 26b and the battery 5 is greater than the distance between the inclined face 26a and the battery 5 when the battery 5 is erected on the groove 26. small. The prismatic battery 5 a is the same battery as the prismatic battery 5 a -20 - 1363447 shown in Fig. 1 1 (a). The prismatic battery 5a of Fig. 16 is placed at a position h2 from the bottom surface of the tray, similarly to Fig. 11(a). As described above, when the prismatic battery 5a is placed, the prismatic battery 5a is located at a position where the square battery 5 is placed and rotated in the direction of the arrow symbol c in Fig. 10 . At this time, as shown in Fig. 11 (a), a gap is formed between the ridge line at the bottom of the prismatic battery 5a and the inclined surface 3b. • In contrast, in Fig. 16, although a gap is formed between the ridge line at the bottom of ΦΦ of the prismatic battery 5a and the inclined surface 26b, the size is larger than the figure _. — — — — — — — — — — — — —* * · 1 1 ( a ) has a small gap. Further, in Fig. 16, the prismatic battery 5b is the same battery as the prismatic battery 5b shown in Fig. 12(a). The square battery 5b is placed at a height h3 from the bottom surface of the tray. Thereby, the gap between the ridge line of the prismatic battery 5b and the inclined surface 26b becomes larger than when the square battery 5a is placed. However, the gap is smaller than the gap in the case where the prismatic battery 5b is placed in the structure of Fig. 11 (a). As described above, according to the configuration of Fig. 16, in the case where a square battery having a large thickness is placed, the gap between the ridge line of the prismatic battery and the inclined surface 26b can be made smaller than that of the structure of Fig. 11. This is because, as described above, the inclined faces 26a, 26b are disposed such that the distance between the inclined faces 26b and the battery 5 is smaller than the distance between the inclined faces 26a and the battery 5. In other words, according to the present embodiment, even if the thickness of the rectangular battery to be housed is increased, the increase in the gap between the ridge line at the bottom of the prismatic battery and the inclined surface can be suppressed. As a result, it is possible to reduce the sway when storing a rectangular battery having a large thickness, and it is possible to achieve stable storage. In addition, the above description has been described by taking an example corresponding to the cross section of the E-E line of Fig. 8 and the G-G line of Fig. 10 of Fig. 10, but for the FF line of Fig. 8 The cross section and the section corresponding to the Η-Η line of Fig. 10 are also the same. However, in this case, the inclined surface that the bottom of the prismatic battery 5b contacts is as shown in FIG. 9(b) and FIG. 11(b), and the opposite sides are provided. Therefore, the inclined surfaces 26a and 26b shown in FIG. The setting of the tilt angle is also reversed.

The shape of the side surface is the same as that of Fig. 1 (b) of the above-described first embodiment, and therefore will not be described. Fig. 18 is a plan view showing the upper tray 32 corresponding to the lower tray 30 of Fig. 17. The shape of the side surface is the same as that of Fig. 3(b) of the above-described first embodiment, and therefore will not be described. In the example of Figs. 17 and 18, the inclined portion inside the accommodating portion 31 of the lower tray 30 is formed into a conical surface, and the opening 33 of the upper tray 32 is formed into a circular shape, so that a cylindrical shape having a different outer diameter can be accommodated. battery. Since the mounting portion has a conical surface, in the present embodiment, a cylindrical battery having a different outer diameter can be accommodated. This will be specifically described with reference to Fig. 19 . Fig. 19 is a cross-sectional view showing a state in which the lower tray 30 of Fig. 17 and the upper tray 32 of Fig. 18 are combined. An inclined portion 34 is formed inside the accommodating portion 31. In the example of Fig. 19, the inclined portion 34 is a conical surface. The entire circumference of the bottom of the accommodated cylindrical battery 35a is in contact with the inclined portion 34. The cylindrical battery 35b is a battery having a larger outer diameter than the cylindrical battery 35a. When the cylindrical battery 35b is housed, the position of the bottom portion -22 - 1363447 becomes higher than that of the bottom portion of the cylindrical battery 35a, but the entire circumference of the bottom portion is in contact with the inclined portion 34 and does not change ' with the cylindrical battery 35a The same can be stored. A cylindrical battery that can be accommodated is, for example, a battery of at least No. 1 (diameter 34 2 mm) to No. 4 (diameter 〇 5 ηιπ1).

In Figs. 17 to 19, the example in which the inclined portion is formed into a conical surface has been described, but the invention is not limited thereto. That is, the inclined portion 34 may be a shape that can be widened toward the opening 33 and can support the bottom of the battery by at least three points, for example, a pyramidal surface. In addition, the inclined portion 34 is not accommodating to the skin, and it is also possible to use a rib inclined or more. Similarly, the opening 33 of the upper tray 32 is not limited to a circular shape, and may be a polygonal shape such as a triangle or more. Further, in the present embodiment, the upper and lower trays can be integrally formed by forming the inner peripheral surface of the opening 33 and the inner peripheral surface of the accommodating portion 31 on the same plane, which is the same as in the third embodiment. [Industrial Applicability] As described above, according to the present invention, since a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray, the battery tray of the present invention can be used, for example, during charging in a compounding step. The trays are used to store trays during the manufacturing process or to store trays for batteries.
