Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and more specifically, to a battery cell tray. Background Technology

[0002] In battery manufacturing, after the cells are hot-pressed and unloaded, they are placed on a cell tray on a cell transport device. The cell transport device moves the cell tray to transfer the cells to the next process.

[0003] However, when the cell operating device starts or stops, or when the moving speed changes abruptly, the cells in the cell tray are easily displaced due to inertia, resulting in damage and large-area dents to the cells.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the aforementioned related technologies and to provide a battery cell tray.

[0006] According to one aspect of this disclosure, a battery cell tray is provided, comprising:

[0007] The support base includes a support portion and at least two side blocking portions. The support portion has a support surface, wherein the two side blocking portions are correspondingly connected to opposite sides of the support portion along a first direction and protrude from the support surface. The first direction is the moving direction of the battery cell tray.

[0008] An anti-slip sleeve is fitted onto at least the side blocking portion and covers the supporting surface. The side of the anti-slip sleeve away from the supporting surface is used to support the battery cell.

[0009] The battery cell tray disclosed herein has two main features. First, an anti-slip sleeve is fitted onto the side blocking portion, which secures the anti-slip sleeve and prevents relative movement between the anti-slip sleeve and the support base due to inertia when the battery cell's operating speed changes during operation. Second, the battery cell is supported on the side of the anti-slip sleeve away from the support surface, meaning the anti-slip sleeve increases the friction between the battery cell and the support surface, further preventing relative movement between the battery cell and the support base, and between the battery cell and the anti-slip sleeve, due to inertia when the battery cell's operating speed changes during operation. In other words, the anti-slip sleeve ensures that even if the battery cell's operating speed changes during operation, there will be no relative movement between the battery cell and the anti-slip sleeve, or between the anti-slip sleeve and the support base, thus preventing damage to the battery cell due to displacement and resulting in large-area dents.

[0010] It should be understood that the general description and detailed description, which follow, are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0029] In this application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through an intermediate medium. "And / or", is only a description of the relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B together, and the existence of B alone. In addition, the character " / " in this paper generally represents an "or" relationship between the front and rear associated objects.

[0030] The example embodiments of the present disclosure provide an electric cell tray, referring to Figures 1-7 The electric cell tray can include a support base 1 and an anti-skid sleeve 2; the support base 1 can include a support part 11 and at least two side edge blocking parts 12, the support part 11 has a support surface 111, and the two side edge blocking parts 12 are connected to the opposite sides of the support part 11 along a first direction X and protrude from the support surface 111, the first direction X is the moving direction of the electric cell tray; the anti-skid sleeve 2 is at least sleeved on the side edge blocking part 12 and covers the support surface 111, and the side of the anti-skid sleeve 2 away from the support surface 111 is used to support the electric cell.

[0031] The electric cell tray of the present disclosure, on the one hand, fixes the anti-skid sleeve 2 through the side edge blocking part 12, so as to avoid that the relative movement between the anti-skid sleeve 2 and the support base 1 occurs due to inertia after the running speed changes during the running of the electric cell. On the other hand, the electric cell is placed on the side of the anti-skid sleeve 2 away from the support surface 111, that is, the anti-skid sleeve 2 is arranged between the electric cell and the support surface 111, so as to increase the friction between the electric cell and the support surface 111, and avoid that the relative movement between the electric cell and the support base 1 and the relative movement between the electric cell and the anti-skid sleeve 2 occur due to inertia after the running speed changes during the running of the electric cell; that is, through the anti-skid sleeve 2, even if the running speed changes during the running of the electric cell, the relative movement between the electric cell and the anti-skid sleeve 2 and the relative movement between the anti-skid sleeve 2 and the support base 1 will not occur, so as to avoid that the electric cell is bruised and the large area is pressed due to the displacement of the electric cell.

[0032] In some example embodiments of the present disclosure, referring to Figures 1-3 The support base 1 can include a support part 11 and at least two side edge blocking parts 12, for example, the support base 1 can include a support part 11 and two side edge blocking parts 12, the support base 1 can also include a support part 11 and three side edge blocking parts 12, and the support base 1 can also include a support part 11 and four side edge blocking parts 12.

[0033] The support part 11 can be provided in the structure of a cuboid, for example, the support part 11 can be provided in the structure of a block of a cuboid, that is, the thickness of the support part 11 is thick; the support part 11 can be provided in the structure of a plate of a cuboid, that is, the thickness of the support part 11 is thin. Of course, the support part 11 can also be other structures, which will not be described here.

[0034] The support part 11 has two oppositely arranged large surfaces, and the large surface is the largest surface of the support part 11, one of the large surfaces is the support surface 111, so that the support part 11 has the support surface 111; the other large surface is attached to the base 3.

[0035] In some exemplary embodiments of this disclosure, the side blocking portion 12 can be configured as a plate. Of course, the side blocking portion 12 can also be configured as a structure in which multiple connecting rods are connected as one piece.

[0036] Two side blocking parts 12 are connected to the opposite sides of the support part 11 along the first direction X, that is, a side blocking part 12 is provided on one side of the support part 11 along the first direction X, and another side blocking part 12 is provided on the opposite side of the support part 11 along the first direction X.

[0037] For example, when two side blocking portions 12 are provided, the two side blocking portions 12 are connected to opposite sides of the support portion 11 along the first direction X in a one-to-one correspondence; when three side blocking portions 12 are provided, the three side blocking portions 12 are connected to three sides of the support portion 11 in a one-to-one correspondence, wherein the two sides are opposite sides along the first direction X; when four side blocking portions 12 are provided, the four side blocking portions 12 are connected to four sides of the support portion 11 in a one-to-one correspondence, wherein each pair of sides is arranged opposite to each other, wherein the two sides are opposite sides along the first direction X.

[0038] It should be noted that the first direction X is the direction of movement of the cell tray, that is, the cell tray moves along the first direction X during the operation of the cell; the second direction Y intersects with the first direction X, for example, the second direction Y is perpendicular to the first direction X; both the first direction X and the second direction Y are parallel to the support surface 111.

[0039] The side blocking part 12 protrudes from the support surface 111, so that the side blocking part 12 can form a block to block the battery cell and prevent the battery cell placed on the support part 11 from falling off the support base 1 due to inertia during operation.

[0040] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the anti-slip sleeve 2 is at least fitted onto the side blocking part 12, and the anti-slip sleeve 2 covers the support surface 111. The side of the anti-slip sleeve 2 away from the support surface 111 is used to support the battery cell.

[0041] The anti-skid sleeve 2 is sleeved outside the side blocking part 12, and the anti-skid sleeve 2 is fixed by the side blocking part 12, so that relative movement between the anti-skid sleeve 2 and the support base 1 is avoided due to inertia when the running speed changes during the running of the battery cell. The battery cell is placed on the side of the anti-skid sleeve 2 away from the support surface 111, that is, the anti-skid sleeve 2 is arranged between the battery cell and the support surface 111, so that the friction between the battery cell and the support surface 111 is increased, and relative movement between the battery cell and the support base 1 and between the battery cell and the anti-skid sleeve 2 is avoided due to inertia when the running speed changes during the running of the battery cell. That is, the anti-skid sleeve 2 ensures that the battery cell and the anti-skid sleeve 2 and the anti-skid sleeve 2 and the support base 1 do not move relatively even when the running speed changes during the running of the battery cell, so that the battery cell is not damaged and large-area indentation is avoided due to displacement of the battery cell.

[0042] In some example embodiments of the present disclosure, the friction coefficient of the side of the anti-skid sleeve 2 away from the support surface 111 is greater than the friction coefficient of the support surface 111. After the battery cell is placed on the side of the anti-skid sleeve 2 away from the support surface 111, the friction coefficient between the battery cell and the anti-skid sleeve 2 is large, so that the battery cell does not move relatively with the anti-skid sleeve 2 due to inertia even when the running speed changes during the running of the battery cell, thereby avoiding damage to the battery cell and large-area indentation due to displacement of the battery cell.

[0043] For example, the friction coefficient of the anti-skid sleeve 2 is greater than or equal to 0.3 and less than or equal to 0.7, for example, the friction coefficient of the anti-skid sleeve 2 can be 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, etc.

[0044] If the friction coefficient of the anti-skid sleeve 2 is too large, it is not conducive to the selection of the material of the anti-skid sleeve 2. If the friction coefficient of the anti-skid sleeve 2 is too small, the friction between the anti-skid sleeve 2 and the battery cell cannot be improved. The above numerical range not only ensures that the friction between the anti-skid sleeve 2 and the battery cell can be improved, but also makes the selection of the material of the anti-skid sleeve 2 easier.

[0045] The elastic modulus can be regarded as an index for measuring the difficulty of elastic deformation of a material, and the greater the value, the greater the stress required to cause a certain elastic deformation of the material, that is, the greater the stiffness of the material, that is, the smaller the elastic deformation under a certain stress.

[0046] In some example embodiments of the present disclosure, the elastic modulus of the anti-skid sleeve 2 is less than the elastic modulus of the support base 1. Under the same force, the anti-skid sleeve 2 is more likely to deform, has a certain buffering performance, can absorb a certain vibration, and reduces the vibration transmitted to the battery cell; and in the case of pressing and fixing the battery cell by the battery cell fixing structure 4, the anti-skid plate 221 can absorb part of the pressing force and generate a certain rebound force to ensure the fixing effect of the battery cell fixing structure 4 on the battery cell.

[0047] For example, the elastic modulus of the anti-slip sleeve 2 is greater than or equal to 0.5 MPa and less than or equal to 1.5 MPa. For example, the elastic modulus of the anti-slip sleeve 2 can be 0.7 MPa, 0.9 MPa, 1 MPa, 1.2 MPa, 1.4 MPa, etc.

[0048] If the elastic modulus of the anti-slip sleeve 2 is too small, it will be difficult to select the material for the anti-slip sleeve 2. If the elastic modulus of the anti-slip sleeve 2 is too large, it will be difficult to absorb vibration. The above-mentioned value range not only makes it easier to select the material for the anti-slip sleeve 2, but also facilitates the absorption of vibration.

[0049] Specifically, the anti-slip sleeve 2 can be made of materials such as rubber, resin, silicone, thermoplastic elastomer, etc., which have certain anti-slip and elastic deformation capabilities.

[0050] In some exemplary embodiments of this disclosure, reference is made to Figure 1 , Figure 2 and Figures 4-6 As shown, the anti-slip sleeve 2 may include a first sleeve portion 21 and a second sleeve portion 22. There are two first sleeve portions 21, and the two first sleeve portions 21 are fitted one-to-one onto two opposite side blocking portions 12 arranged along the first direction X, that is, one first sleeve portion 21 is fitted onto one side blocking portion 12.

[0051] Of course, in some other exemplary embodiments of this disclosure, when three side blocking portions 12 are provided, the first sleeve portion 21 can be provided as three, with the three first sleeve portions 21 correspondingly fitted onto the three side blocking portions 12; or the first sleeve portion 21 can be provided as two, with the two first sleeve portions 21 correspondingly fitted onto the two side blocking portions 12 arranged opposite to each other along the first direction X. When four side blocking portions 12 are provided, the first sleeve portion 21 can be provided as four, with the four first sleeve portions 21 correspondingly fitted onto the four side blocking portions 12; or the first sleeve portion 21 can be provided as two, with the two first sleeve portions 21 correspondingly fitted onto the two side blocking portions 12 arranged opposite to each other along the first direction X.

[0052] After the battery cell is supported by the second sleeve 22, a first gap is provided between the battery cell and the first sleeve 21. The width of the first gap along the first direction X is greater than or equal to 1 mm and less than or equal to 1.5 mm. That is, the difference between the distance between the two first sleeves 21 along the first direction X and the width of the battery cell along the first direction X is greater than or equal to 2 mm and less than or equal to 3 mm. For example, the width of the first gap along the first direction X can be 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.35 mm, 1.4 mm, 1.45 mm, etc.

[0053] If the width of the first gap along the first direction X is too large, the battery cell is prone to slide on the anti-skid sleeve 2; if the width of the first gap along the first direction X is too small, the battery cell is not easy to put in and is prone to be extruded. The above numerical range not only ensures that the battery cell is not prone to slide on the anti-skid sleeve 2, but also is easy to put in and will not extrude the battery cell.

[0054] The width of the first gap between the battery cell and the two first sleeve portions 21 can be the same or different.

[0055] Specifically, referring to Figures 4-6 As shown in the figure, the first sleeve portion 21 can include a first side plate 211, a second side plate 212, a third side plate 213, a fourth side plate 214, and a top plate 215. The first side plate 211, the second side plate 212, the third side plate 213, and the fourth side plate 214 are sequentially connected end to end to form a rectangular frame, the first side plate 211 is arranged opposite to the third side plate 213, and the second side plate 212 is arranged opposite to the fourth side plate 214; the top plate 215 is connected to the top ends of the first side plate 211, the second side plate 212, the third side plate 213, and the fourth side plate 214, and the bottom of the first sleeve portion 21 forms a first opening, through which the first sleeve portion 21 can be sleeved on the side blocking portion 12. The first side plate 211 is closer to the second sleeve portion 22 relative to the third side plate 213, that is, the first side plate 211 is arranged on the inner side, and the third side plate 213 is arranged on the outer side.

[0056] The height of the first side plate 211 in the third direction Z is less than the height of the third side plate 213 in the third direction Z, so that the third side plate 213 protrudes from the first side plate 211 at the first opening, the first side plate 211 can abut against the support surface 111, the second side plate 212, the third side plate 213, and the fourth side plate 214 extend below the support surface 111, and the sides of the second side plate 212, the third side plate 213, and the fourth side plate 214 away from the top plate 215 are flushly arranged; facilitating the subsequent connection of the fifth side plate 222 and the two second side plates 212 and the connection of the sixth side plate 223 and the two fourth side plates 214.

[0057] Of course, in some other example embodiments of the present disclosure, the height of the first side plate 211 in the third direction Z can be equal to the height of the third side plate 213 in the third direction Z, so that the third side plate 213 is flush with the first side plate 211 at the first opening; the height of the first side plate 211 in the third direction Z can also be greater than the height of the third side plate 213 in the third direction Z, so that the first side plate 211 protrudes from the third side plate 213 at the first opening.

[0058] The second sleeve portion 22 is connected between the two first sleeve portions 21. The second sleeve portion 22 is sleeved on the support portion 11 to cover the support surface 111.

[0059] Specifically, the second sleeve 22 may include an anti-slip plate 221, a fifth side plate 222, and a sixth side plate 223. The fifth side plate 222 and the sixth side plate 223 are connected to opposite sides of the anti-slip plate 221 in the second direction Y, such that the second sleeve 22 is configured as a "[" shape. The two sides of the anti-slip plate 221 in the first direction X are connected to the first side plates 211 of the two first sleeves 21.

[0060] The fifth side plate 222 is connected between the two second side plates 212 of the two first sleeve parts 21 to prevent the fifth side plate 222 from forming a free end. During use, the fifth side plate 222 is prone to deformation and warping, which can cause the first sleeve parts 21 to fall off easily.

[0061] The sixth side plate 223 is connected between the two fourth side plates 214 of the two first sleeve parts 21 to prevent the sixth side plate 223 from forming a free end. During use, the sixth side plate 223 is prone to deformation and warping, which can cause the first sleeve parts 21 to fall off easily.

[0062] Of course, in some other exemplary embodiments of this disclosure, the second sleeve 22 may also be plate-shaped, that is, the second sleeve 22 may only include the anti-slip plate 221, only cover the support surface 111, and not include the fifth side plate 222 and the sixth side plate 223.

[0063] In some exemplary embodiments of this disclosure, reference is made to Figure 3 As shown, a first recess 1111 is provided on the support surface 111, and the shape of the first recess 1111 can be the same as the shape of the support surface 111. For example, when the support surface 111 is set as a rectangle, the first recess 1111 can be set as a rectangle; when the support surface 111 is set as a circle, the first recess 1111 can be set as a circle; when the support surface 111 is set as an ellipse, the first recess 1111 can be set as an ellipse.

[0064] Reference Figure 5 As shown, a first protrusion 224 is provided on the side of the second sleeve 22 near the support surface 111. The shape of the first protrusion 224 can be the same as the shape of the first recess 1111. For example, if the first recess 1111 is rectangular, the first protrusion 224 can be rectangular; if the first recess 1111 is circular, the first protrusion 224 can be circular; if the first recess 1111 is elliptical, the first protrusion 224 can be elliptical.

[0065] Of course, in some other example embodiments of the present disclosure, the shape of the first recess 1111 can also be different from the shape of the support surface 111. The shape of the first protrusion 224 can also be different from the shape of the first recess 1111. The shape of the support surface 111 and the shape of the first recess 1111 and the shape of the first protrusion 224 can also be other regular or irregular shapes, which will not be described here.

[0066] In addition, the number of the first recess 1111 can also be two or more, and the number of the first protrusion 224 can also be two or more. Generally, the number of the first recess 1111 is the same as the number of the first protrusion 224.

[0067] Alternatively, the first protrusion 224 is interference fitted in the first recess 1111, so that the connection between the first protrusion 224 and the first recess 1111 is more closely, that is, the first protrusion 224 is embedded in the first recess 1111. Through the first protrusion 224 and the first recess 1111, the connection strength between the second sleeve 22 and the support seat 1 can be increased, and the second sleeve 22 can be prevented from falling off the support seat 1.

[0068] Of course, in some other example embodiments of the present disclosure, the first protrusion 224 can also be clearance fitted in the first recess 1111.

[0069] Alternatively, the ratio of the area of the first recess 1111 to the area of the support surface 111 is greater than or equal to 0.5 and less than 1, for example, the ratio of the area of the first recess 1111 to the area of the support surface 111 can be 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.92, 0.94, 0.95, 0.96, 0.98, etc. That is, the first recess 1111 occupies most of the area of the support surface 111.

[0070] Optionally, the height of the first protruding part 224 is greater than or equal to the depth of the first recessed part 1111. In the case that the height of the first protruding part 224 is equal to the depth of the first recessed part 1111, the first recessed part 1111 can be filled by the first protruding part 224; in the case that the height of the first protruding part 224 is greater than the depth of the first recessed part 1111, the first recessed part 1111 can be filled by the first protruding part 224, and the first protruding part 224 protrudes from the first recessed part 1111. In this way, the total thickness of the anti-skid plate 221 is set to be thicker at the position of the first protruding part 224, so that the anti-skid plate 221 has better buffering performance and can absorb more vibration, reducing the vibration transmitted to the battery cell. Moreover, in the case that the battery cell is pressed and fixed by the battery cell fixing structure 4, the anti-skid plate 221 can absorb part of the pressing force, and a certain rebound force can be generated to ensure the fixing effect of the battery cell fixing structure 4 on the battery cell.

[0071] Of course, in some other example embodiments of the present disclosure, the first protruding part 224 can be arranged on the support surface 111, and the first recessed part 1111 can be arranged on the side of the second sleeve part 22 close to the support surface 111.

[0072] In some example embodiments of the present disclosure, referring to Figure 1 As shown in the figure, the battery cell tray can further include a base 3 and a battery cell fixing structure 4; the support seat 1 is arranged on the base 3, specifically, a counterbore is arranged on the support seat 1, and a threaded hole is arranged on the base 3, a screw passes through the counterbore and is threadedly connected to the threaded hole, so that the support seat 1 is fixed to the base 3 by the screw; and the counterbore makes the screw not protrude from the support surface 111 of the support seat 1, so as to ensure the flatness of the support surface 111 and provide a flat support surface 111 for the battery cell.

[0073] The battery cell fixing structure 4 is connected to the base 3, and the battery cell fixing structure 4 can be used to abut against the battery cell supported on the anti-skid sleeve 2. One support seat 1 is provided with one battery cell fixing structure 4 on one side in the first direction X, and one support seat 1 is provided with two battery cell fixing structures 4 on both sides in the first direction X, that is, one battery cell is fixed by abutting against the two battery cell fixing structures 4.

[0074] Referring to Figure 1 and Figure 7As shown, the battery cell fixing structure 4 can be an elastic fixing structure. Specifically, the battery cell fixing structure 4 can include a fixing base 41, four connecting ears 42, two rotating shafts 43, two torsional springs 44, and a clamping part 45; the fixing base 41 is fixed to the base 3, and four connecting ears 42 are arranged on the side of the fixing base 41 away from the base 3, and through holes are arranged on the connecting ears 42. One rotating shaft 43 is rotatably connected with two connecting ears 42, that is, the rotating shaft 43 penetrates the through holes on the two connecting ears 42, so that the rotating shaft 43 can rotate relative to the connecting ears 42. One torsional spring 44 is arranged on one rotating shaft 43, and two torsional springs 44 are arranged on the two rotating shafts 43.

[0075] The clamping part 45 can include two clamping plates 451, two pressing wheels 452, and a connecting force applying part 453; the pressing wheel 452 is rotatably connected to one end of the clamping plate 451, and the pressing wheel 452 is used for tightly fixing the battery cell; when pressed, the sliding friction can be converted into rolling friction, reducing the friction force; and the generation of the pressure mark on the battery cell is reduced. The opposite end of the clamping plate 451 is provided with two connecting protrusions, through holes are arranged on the connecting protrusions, and the two ends of the rotating shaft 43 penetrate the two through holes one by one. The torsional spring 44 has a straight fixed end and a straight movable end, the straight fixed end abuts against the fixing base 41, and the straight movable end abuts against the clamping plate 451; the connecting force applying part 453 is connected to the two connecting protrusions of the two clamping plates 451 that are close to each other, and the connecting force applying part 453 is bent away from the fixing base 41.

[0076] Pressing the connecting force applying part 453 downward can make the clamping plate 451 rotate upward, so that the battery cell can be moved to the anti-skid sleeve 2 through the elastic fixing structure; releasing the connecting force applying part 453 makes the clamping plate 451 rotate downward under the action of the torsional spring 44, so as to fix the battery cell supported on the anti-skid sleeve 2.

[0077] A bearing 454 is arranged on the connecting force applying part 453, which can convert sliding friction into rolling friction when pressed, reducing the friction force; and facilitating assembly with a mechanical hand for applying pressure.

[0078] Alternatively, a first avoiding part 121 is arranged on the side edge blocking part 12, specifically, referring to Figure 3 As shown, a first groove is arranged on the end of the side edge blocking part 12 away from the supporting part 11, and the first groove is the first avoiding part 121; the first groove can be one, so that the side edge blocking part 12 forms a “concave” shape; the first groove can also be two or more, and the number of the first groove can be determined according to the number of the battery cell fixing structure 4, for example, the number of the first groove can be the same as the number of the battery cell fixing structure 4.

[0079] Referring to Figure 4 and Figure 6As shown, the anti-skid sleeve 2 is provided with a second avoiding portion 216, that is, the first sleeve portion 21 is provided with the second avoiding portion 216, specifically, the first side plate 211 and the third side plate 213 are both provided with a second groove, and the top plate 215 is provided with a rectangular sawtooth structure, and the recess of the top plate 215 cooperates with the second groove to form the second avoiding portion 216. The second avoiding portion 216 can be one, so that the first sleeve portion 21 forms a “concave” shape; the second avoiding portion 216 can also be two or more, and the number of the second avoiding portion 216 can be determined according to the number of the battery cell fixing structure 4, for example, the number of the second avoiding portion 216 can be the same as the number of the battery cell fixing structure 4.

[0080] The second avoiding portion 216 cooperates with the first avoiding portion 121, that is, after the first sleeve portion 21 is sleeved on the side edge blocking portion 12, the second avoiding portion 216 cooperates with the first avoiding portion 121 to form an avoiding structure, and the battery cell fixing structure 4 penetrates through the avoiding structure, that is, the first avoiding portion 121 and the second avoiding portion 216 are used for avoiding the battery cell fixing structure 4, that is, the avoiding structure formed by the first avoiding portion 121 and the second avoiding portion 216 can make the battery cell fixing structure 4 penetrate through.

[0081] In some example embodiments of the present disclosure, reference is made to Figure 1 As shown, the battery cell tray can further include two tab supports 5, and the two tab supports 5 are arranged on the base 3. Specifically, the tab support 5 is provided with a recess structure, and a through hole is arranged in the recess structure. A threaded hole is arranged on the base 3, and a screw penetrates through the through hole and is threadedly cooperated with the threaded hole, so as to fix the tab support 5 to the base 3 through the screw. Moreover, the recess structure makes the screw not protrude from the support surface 111 of the tab support 5, so as to ensure the flatness of the support surface 111 and provide a flat support surface 111 for the tab.

[0082] The two tab supports 5 are located on opposite sides of the support seat 1 along the second direction Y one by one, that is, one tab support 5 is arranged on one side of the support seat 1 along the second direction Y. The tab support 5 is used for supporting the tab, that is, the two tabs on opposite sides of the battery cell along the second direction Y can be supported through the two tab supports 5, so as to avoid the tab from drooping during the operation of the battery cell.

[0083] It should be noted that the second direction Y intersects the first direction X, for example, the second direction Y is perpendicular to the first direction X.

[0084] Of course, in another example embodiment of the present disclosure, one tab support 5 can also be arranged, and the one tab support 5 is arranged on one side of the support seat 1 along the second direction Y.

[0085] Alternatively, the distance between the side of the tab support member 5 away from the base 3 and the base 3 is less than the distance between the side of the anti-skid sleeve 2 away from the support surface 111 and the base 3, that is, the side of the tab support member 5 away from the base 3 is lower than the side of the anti-skid sleeve 2 away from the support surface 111, so that the tab support member 5 can well support the tab.

[0086] Specifically, the distance between the side of the tab support member 5 away from the base 3 and the side of the anti-skid sleeve 2 away from the support surface 111 is greater than or equal to 0.5 mm and less than or equal to 1 mm, for example, the distance between the side of the tab support member 5 away from the base 3 and the side of the anti-skid sleeve 2 away from the support surface 111 can be 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, etc.

[0087] One support base 1, one anti-skid sleeve 2 and two tab support members 5 form a set of support structure, the support structure is provided as at least two sets, for example, the support structure can be provided as two sets, the two sets of support structure can be arranged at intervals along the first direction X, the two sets of support structure can also be arranged at intervals along the second direction Y; the support structure can also be provided as three sets or more sets, the three sets or more sets of support structure can be arranged at intervals along the first direction X, the three sets or more sets of support structure can also be arranged at intervals along the second direction Y; the three sets or more sets of support structure can also be arranged in an array, the three sets or more sets of support structure can also be arranged in a regular or irregular shape, which will not be described here.

[0088] Based on the same inventive concept, the example embodiments of the disclosure provide an electric cell operating device, which can include an electric cell tray, the electric cell tray being any one of the above-mentioned electric cell trays, and the specific structure of the electric cell tray has been described in detail above, so this will not be described here.

[0089] The electric cell operating device can further include an operating part, and the electric cell tray is arranged in the operating part, and the operating part can drive the electric cell tray to move along the first direction X.

[0090] The electric core running device of the present disclosure, on the one hand, fixes the anti-skid sleeve 2 through the side blocking part 12, so as to avoid the relative movement between the anti-skid sleeve 2 and the support base 1 due to inertia when the running speed of the electric core running device changes during the running of the electric core. On the other hand, the electric core is placed on the side of the anti-skid sleeve 2 away from the support surface 111, that is, the anti-skid sleeve 2 is arranged between the electric core and the support surface 111, so as to increase the friction between the electric core and the support surface 111, and avoid the relative movement between the electric core and the support base 1 and the relative movement between the electric core and the anti-skid sleeve 2 due to inertia when the running speed of the electric core running device changes during the running of the electric core. That is, through the anti-skid sleeve 2, even if the running speed changes during the running of the electric core, the electric core and the anti-skid sleeve 2 and the anti-skid sleeve 2 and the support base 1 will not move relatively, so as to avoid the electric core from being bruised and large area pressed due to the displacement of the electric core.

[0091] The "parallel" and "vertical" mentioned in the present application can not only be completely parallel and vertical, but also can have a certain error; for example, the included angle between the two is greater than or equal to 0° and less than or equal to 5°, that is, the two are considered to be parallel to each other; the included angle between the two is greater than or equal to 85° and less than or equal to 95°, that is, the two are considered to be perpendicular to each other.
