TECHNICAL FIELD

[0001] The present application relates to the technical field of battery production, and more particularly, to a transfer device and production equipment. BACKGROUND

[0002] Before entering the shell, the battery cell needs to be placed on the transfer device for carrying and transferring to undergo different processes for processing and manufacturing. During the transfer process, the battery cell is prone to shaking and colliding with the transfer device, even causing damage. CONTENT OF THE UTILITY MODEL

[0003] In view of the above problems, the present application provides a transfer device and production equipment, which can prevent the battery cell from colliding with the transfer device, thereby improving the qualified rate of the battery cell.

[0004] In a first aspect, the present application provides a transfer device, comprising: a base having a carrying surface on one side along a first direction; a locking mechanism arranged on the base and at least partially protruding from the carrying surface along the first direction, the locking mechanism comprising at least two locking members spaced apart from each other, each locking member enclosing a clamping cavity, and the locking member being capable of rotating relative to the base about an axis intersecting the first direction to adjust the size of the area of the clamping cavity in the first direction.

[0005] In some embodiments of the first aspect, by arranging the locking mechanism on the base at least partially protruding from the carrying surface, the locking mechanism comprises at least two locking members enclosing a clamping cavity, when the battery cell is placed in the clamping cavity for transfer, the locking member can rotate relative to the base about an axis intersecting the first direction to increase or decrease the area of the clamping cavity in the first direction, so that the volume of the clamping cavity can be adjusted to the size that can just accommodate the battery cell, the locking member can provide clamping force for the battery cell to prevent the battery cell from shaking during the transfer process, thereby avoiding the battery cell from colliding and causing damage, and improving the qualified rate of the battery cell.

[0006] In some embodiments, the locking member is detachably connected to the base. By this way of arrangement, it is convenient to maintain and replace the locking member, and different specifications of the locking member can be replaced to be suitable for different specifications of the battery cell, thereby improving the versatility.

[0007] In some embodiments, the base has a groove recessed inward from the carrying surface, and the locking member is partially arranged in the groove and gap-fitted with the groove. The part of the locking member can be arranged in the groove, so that the locking member is more tightly connected with the base, thereby improving the space utilization of the whole transfer device.

[0008] In some embodiments, the locking member comprises a pressure receiving part, a rotating part, and clamping parts, at least part of each clamping part protrudes from the bearing surface in the first direction and encloses a clamping cavity, the pressure receiving part and the clamping part are intersected and connected to the rotating part, the pressure receiving part is configured to receive external force to drive the clamping part to rotate relative to the base through the rotating part, and the clamping part is configured to drive the pressure receiving part to rotate relative to the base through the rotating part when the pressure receiving part loses external force.

[0009] In the above technical solution, when the pressure receiving part receives external force, the pressure receiving part rotates relative to the base through the rotating part, and at the same time drives the clamping part to rotate to adjust the volume of the clamping cavity, so that it can clamp the battery monomer to prevent it from shaking; when the external force applied to the pressure receiving part is removed, the clamping part rotates relative to the base in the opposite direction through the rotating part to adjust the volume of the clamping cavity, and at the same time drives the pressure receiving part to rotate to make them return to the initial position, waiting for the next transfer. By this way, the locking member can be adaptively rotated to adjust the volume of the clamping cavity, meeting the limiting requirement of the battery monomer.

[0010] In some embodiments, the pressure receiving part and the clamping part are fixedly connected to the rotating part, and the rotating part is rotatably connected to the base. By this way, assembly is facilitated.

[0011] In some embodiments, in the first direction, the orthogonal projection of the pressure receiving part overlaps with the orthogonal projection of the clamping cavity. By this way, the pressure receiving part can receive the pressure provided by the battery monomer to rotate relative to the base through the rotating part, so that the locking mechanism can be adaptively rotated to adjust the volume of the clamping cavity, which is convenient to operate and helps to improve the transfer efficiency of the transfer device.

[0012] In some embodiments, the locking mechanism and the base can be switched between a first cooperation position and a second cooperation position; in the first cooperation position, the clamping part and the bearing surface have a first included angle, and the clamping cavity has a first orthogonal projection area in the first direction; in the second cooperation position, the clamping part and the bearing surface have a second included angle, and the clamping cavity has a second orthogonal projection area in the first direction, the second orthogonal projection area is smaller than the first orthogonal projection area, and the second included angle is greater than the first included angle.

[0013] In the above technical solution, when the transfer device does not carry the battery monomer, the locking mechanism and the base are in the first cooperation position, and when the transfer device carries the battery monomer, the locking mechanism and the base are in the second cooperation position, the orthogonal projection area of the clamping cavity in the first direction is reduced and the clamping part can be rotated towards the battery monomer, so that the locking mechanism can better clamp the battery monomer to prevent it from shaking.

[0014] In some embodiments, in the first cooperation position, at least part of the pressure receiving part protrudes from the bearing surface in the first direction, and in the second cooperation position, the pressure receiving part extends into the interior of the base.

[0015] In this way, the pressure receiving portion can receive the pressure provided by the battery cell, and the battery cell can press the pressure receiving portion into the base, so that the battery cell can abut against the bearing surface of the base, thereby increasing the bearing area of the base on the battery cell, and the battery cell is more stable during transportation.

[0016] In some embodiments, the clamping portion includes clamping bodies and a counterweight component, each clamping body enclosing a clamping cavity, the clamping bodies and the pressure receiving portion are arranged at the intersection and are connected to the rotating portion, and the counterweight component is arranged on the side of the clamping body away from the clamping cavity. In this way, the clamping portion can drive the pressure receiving portion to rotate effectively.

[0017] In some embodiments, the counterweight component is detachably connected to the clamping body. In this way, different specifications of the counterweight component can be replaced, thereby improving the flexibility of the transportation device.

[0018] In some embodiments, the pressure receiving portion is arranged in connection with the clamping portion, and the rotating portion is arranged at the intersection of the pressure receiving portion and the clamping portion. Such a design facilitates assembly.

[0019] In some embodiments, the pressure receiving portion and the clamping portion are an integral structure. In this way, the processing efficiency is improved, and the reliability of synchronous rotation of the two is also improved.

[0020] In some embodiments, the locking member further includes an elastic portion, and at least one of the pressure receiving portion and the clamping portion is provided with an elastic portion on the side facing the clamping cavity. Such a design facilitates the protection of the battery cell when the locking member clamps the battery cell.

[0021] In some embodiments, the clamping portion is provided with an elastic portion on the side facing the clamping cavity, and the side surface of the elastic portion away from the clamping portion and the side surface of the clamping portion facing the elastic portion have an included angle; the side surface of the elastic portion away from the clamping portion has a first end and a second end in the first direction, the first end is arranged toward the base and the second end is arranged away from the base, and the minimum distance between the elastic portion and the first end is smaller than the minimum distance between the elastic portion and the second end. In this way, the friction between the elastic portion and the battery cell can be increased, thereby improving the clamping effect of the locking member on the battery cell.

[0022] In some embodiments, the pressure receiving portion has a flat structure, the clamping portion has a flat structure, or the clamping portion has an arc-shaped structure and is recessed on the side away from the pressure receiving portion. In this way, the flexibility of the locking member is improved.

[0023] In some embodiments, the transfer device further comprises a limiting member, the limiting member is arranged on the base and at least partially protrudes from the bearing surface in the first direction, the limiting member is spaced apart from each locking member and together with each locking member forms a clamping cavity.

[0024] In some embodiments, the base has a clamping jaw groove recessed inwardly from the bearing surface, the clamping jaw groove is arranged extending in the second direction, the clamping jaw groove is provided with a locking member and a limiting member on both sides in the third direction, in the third direction, the minimum distance between the at least one limiting member and the clamping jaw groove is greater than the minimum distance between the locking member and the clamping jaw groove, and the first direction, the second direction and the third direction are arranged intersecting each other.

[0046] Currently, market developments indicate that battery applications are becoming increasingly widespread. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As battery applications continue to expand, market demand is also growing.

[0047] A battery device generally includes battery cells. Before being placed in a shell, the battery cells need to be placed on a transport device for carrying and transporting, so as to undergo different processing steps. During the transport process, the battery cells are prone to shaking, causing collisions with the transport device or even damage.

[0048] To address the above technical issues, embodiments of the present application provide a transfer device comprising a base and a locking mechanism. The base has a bearing surface on one side along a first direction. The locking mechanism is disposed on the base and at least partially protrudes from the bearing surface along the first direction. The locking mechanism comprises at least two locking members spaced apart from each other, each of which encloses a clamping cavity. The locking members are rotatable relative to the base about an axis intersecting the first direction to adjust the size of the orthographic projection of the clamping cavity in the first direction.

[0049] likeFigure 1 In the embodiments of the present application, the first direction is the X-axis direction, which can be represented as the thickness or height direction of the base.

[0050] By arranging the locking mechanism on the base to at least partially protrude from the bearing surface, the locking member included in the locking mechanism can rotate relative to the base about an axis in a direction intersecting the first direction, so as to increase or decrease the area of the projection of the clamping cavity in the first direction, so that the volume of the clamping cavity can be adjusted to a size just capable of accommodating the battery monomer, preventing the battery monomer from shaking during transfer, so as to avoid the situation that the battery monomer is damaged due to collision, and facilitating to improve the qualified rate of the battery monomer.

[0051] The transfer device provided in the embodiments of the present application can be produced and sold independently as a separate component, and can also be used in production equipment as a part of the production equipment. The transfer device provided in the embodiments of the present application can be applied to products having transfer requirements on the bearing logistics line, and the products can include but are not limited to battery monomers. For the convenience of description, the transfer device will be described below by taking the battery monomer as an example.

[0052] Please refer to Figures 1 to 3 , according to the embodiments of the present application, a transfer device 100 is provided, which includes a base 10 and a locking mechanism 20. The base 10 has a bearing surface 101 on one side along a first direction X. The locking mechanism 20 is arranged on the base 10 and at least partially protrudes from the bearing surface 101 along the first direction X. The locking mechanism 20 includes at least two locking members 21 distributed at intervals from each other, each locking member 21 forms a clamping cavity 201, and the locking member 21 can rotate relative to the base 10 about an axis in a direction intersecting the first direction X, so as to adjust the size of the projection of the clamping cavity 201 in the first direction X.

[0053] The base 10 is used to place the locking mechanism 20 and the battery monomer 200, so as to bear the battery monomer 200 during the transfer of the battery monomer 200 by the transfer device 100.

[0054] The base 10 has a bearing surface 101 on one side along the first direction X, the bearing surface 101 is used to mount the locking mechanism 20, and the locking mechanism 20 and the battery monomer 200 are arranged close to the bearing surface 101. The base 10 also has a transfer surface on the side away from the bearing surface 101 along the first direction X, and the transfer surface is used to cooperate with the transportation mechanism on the logistics line.

[0055] The locking mechanism 20 is used to clamp and limit the battery monomer 200, so that the battery monomer 200 does not shake during the transfer and is stably placed on the transfer device 100. The locking mechanism 20 at least partially protrudes from the bearing surface 101 along the first direction X, so as to ensure that it can clamp the battery monomer 200 to limit it.

[0056] The locking mechanism 20 can be entirely protruded from the bearing surface 101 in the first direction X, that is, the locking mechanism 20 is connected to the bearing surface 101; or the locking mechanism 20 can be partially protruded from the bearing surface 101 in the first direction X, that is, the locking mechanism 20 is partially arranged inside the base 10, and the locking mechanism 20 can be connected to the bearing surface 101 and also connected to the inside of the base 10.

[0057] The locking mechanism 20 includes at least two locking pieces 21 distributed at intervals from each other, and the number of the locking pieces 21 can be two, three, or more, and the number of the locking pieces 21 can be set according to the size of the battery monomer 200 to be transported.

[0058] Each locking piece 21 encloses a clamping cavity 201 for accommodating the battery monomer 200. Optionally, the shape of the clamping cavity 201 can include but is not limited to a rectangle, a circle, etc., and the shape of the clamping cavity 201 matches the shape of the battery monomer 200 to be transported.

[0059] The locking piece 21 can rotate relative to the base 10 about an axis in a direction intersecting the first direction X, that is, the locking piece 21 can rotate towards or away from the clamping cavity 201, and the locking piece 21 can rotate relative to the base 10 about an axis in a second direction Y or a third direction Z.

[0060] The first direction X can be the height direction of the base 10, the second direction Y can be the length direction of the base 10, and the third direction Z can be the width direction of the base 10; or the second direction Y can be the width direction of the base 10, and the third direction Z can be the length direction of the base 10.

[0061] The size of the orthographic projection area of the clamping cavity 201 in the first direction X can be understood as the projection area of the clamping cavity 201 on the base 10 in the first direction X.

[0062] The locking piece 21 can rotate relative to the base 10 to increase or decrease the orthographic projection area of the clamping cavity 201 in the first direction X, so as to increase or decrease the volume of the clamping cavity 201, so as to adjust the volume of the clamping cavity 201 to just accommodate the battery monomer 200, and the locking piece 21 can abut and clamp the battery monomer 200.

[0063] Specifically, the battery cell 200 is placed in the clamping cavity 201, the locking member 21 rotates relative to the base 10 about an axis intersecting the first direction X to adjust the size of the orthographic projection area of the clamping cavity 201 in the first direction X, and when the battery cell 200 is completely placed in the clamping cavity 201, the locking member 21 no longer rotates, and the orthographic projection area of the clamping cavity 201 in the first direction X no longer changes. The locking member 21 can abut against the battery cell 200 to provide clamping force, so that the battery cell 200 is stably placed in the clamping cavity 201.

[0064] The transport device 100 has a first projection area of the clamping cavity 201 in the first direction X when the battery cell 200 is not placed, and the locking member 21 can rotate relative to the base 10 about an axis intersecting the first direction X to adjust the size of the orthographic projection area of the clamping cavity 201 in the first direction X when the battery cell 200 is placed in the clamping cavity 201. The clamping cavity 201 has a second projection area in the first direction X when the battery cell 200 is completely placed in the clamping cavity 201.

[0065] In some embodiments, the first projection area is smaller than the second projection area, that is, the locking member 21 can move to the side away from the clamping cavity 201 when the battery cell 200 is placed in the clamping cavity 201.

[0066] In other embodiments, the first projection area is larger than the second projection area, that is, the locking member 21 can move to the side toward the clamping cavity 201 when the battery cell 200 is placed in the clamping cavity 201.

[0067] The transport device 100 provided by some embodiments of the present application can rotate the locking member 21 relative to the base 10 about an axis intersecting the first direction X when the battery cell 200 is placed in the clamping cavity 201 for transport, so as to increase or decrease the orthographic projection area of the clamping cavity 201 in the first direction X. The volume of the clamping cavity 201 can be adjusted to just the size that can accommodate the battery cell 200. The locking member 21 can provide clamping force for the battery cell 200 to prevent the battery cell 200 from shaking during transport, so as to avoid the situation that the battery cell 200 collides with the transport device 100 and is damaged, thereby improving the qualified rate of the battery cell 200.

[0068] Optionally, the locking member 21 can be controlled by a driving member such as a pneumatic cylinder to rotate.

[0069] Optionally, the locking member 21 can also rotate adaptively through pressure triggering.

[0070] Optionally, the base 10 can be provided with a locking mechanism 20, that is, the base 10 has a clamping cavity 201 for placing a battery monomer 200, or the base 10 can be provided with two or more locking mechanisms 20, that is, the base 10 has two or more clamping cavities 201 for carrying two or more battery monomers 200.

[0072] In some optional embodiments, the locking member 21 is detachably connected to the base 10.

[0073] It can be understood that each locking member 21 encloses a clamping cavity 201 for accommodating a battery monomer 200, and therefore, in order to make the transfer device 100 applicable to transfer battery monomers 200 of different specifications, the above-mentioned manner can be used to replace locking members 21 of different specifications according to needs, so as to change the size of the clamping cavities 201 enclosed by the locking members 21, which can improve the versatility of the transfer device 100, save production costs, and facilitate maintenance and replacement of the locking members 21.

[0074] Optionally, the locking member 21 can be detachably connected to the base 10 through, but not limited to, bolts, screws and the like fasteners.

[0075] As shown in Figure 1 and Figure 2 In some optional embodiments, the base 10 has a groove 102 recessed inwardly from the bearing surface 101, and the locking member 21 is partially arranged in the groove 102 and gap-fitted with the groove 102.

[0076] A part of the locking member 21 can be arranged in the groove 102 to be gap-fitted with the groove 102, and another part of the locking member 21 protrudes from the bearing surface 101 in the first direction X to enclose the clamping cavity 201.

[0077] The transfer device 100 provided by some embodiments of the present application is arranged in the above-mentioned manner, so that the locking member 21 is more closely connected to the base 10, which is beneficial to improve the space utilization of the transfer device 100 as a whole.

[0078] Please refer to Figures 1 to 5In some optional embodiments, the locking member 21 comprises a pressure receiving portion 211, a rotating portion 212, and a clamping portion 213, at least part of each clamping portion 213 protrudes from the bearing surface 101 in the first direction X and encloses a clamping cavity 201, the pressure receiving portion 211 and the clamping portion 213 are arranged at intersections and are both connected to the rotating portion 212, the pressure receiving portion 211 is configured to receive external force to drive the clamping portion 213 to rotate relative to the base 10 through the rotating portion 212, and the clamping portion 213 is configured to drive the pressure receiving portion 211 to rotate relative to the base 10 through the rotating portion 212 when the pressure receiving portion 211 loses external force.

[0079] The pressure receiving portion 211 and the clamping portion 213 are arranged at intersections, that is, they have an included angle between their extension directions, and both are connected to the rotating portion 212, so that they can rotate relative to the base 10 through the rotating portion 212 with the direction intersecting the first direction X as the axis.

[0080] Alternatively, the pressure receiving portion 211 and the clamping portion 213 can be arranged in connection, and the whole after connection is connected to the rotating portion 212; or the pressure receiving portion 211 and the clamping portion 213 can be connected to the rotating portion 212 respectively.

[0081] The pressure receiving portion 211 is used to receive external force, so that it can drive the clamping portion 213 to rotate relative to the base 10 through the rotating portion 212; the clamping portion 213 is used to provide clamping force for the battery monomer 200, so that the battery monomer 200 will not shake, and when the external force acting on the pressure receiving portion 211 is removed, the clamping portion 213 can drive the pressure receiving portion 211 to rotate in the opposite direction.

[0082] The pressure receiving portion 211 can drive the clamping portion 213 to rotate, and the clamping portion 213 can also drive the pressure receiving portion 211 to rotate, that is, the relative position of the pressure receiving portion 211 and the clamping portion 213 is fixed, and the pressure receiving portion 211 and the clamping portion 213 can rotate synchronously.

[0083] In the transfer device 100 provided in some embodiments of the present application, when the pressure-bearing part 211 receives an external force, the pressure-bearing part 211 rotates relative to the base 10 through the rotating part 212, and at the same time drives the clamping part 213 to rotate to adjust the size of the positive projection area of ​​the clamping cavity 201 in the first direction X, so that it can clamp the battery cell 200 to prevent it from shaking; when the external force applied to the pressure-bearing part 211 is removed, the clamping part 213 rotates in the opposite direction relative to the base 10 through the rotating part 212 to adjust the size of the positive projection area of ​​the clamping cavity 201 in the first direction X, and at the same time drives the pressure-bearing part 211 to rotate so that the two return to their initial positions to wait for the next transfer. Through this arrangement, the locking member 21 can adaptively rotate to adjust the size of the positive projection area of ​​the clamping cavity 201 in the first direction X, thereby meeting the limiting requirements of the battery cell 200.

[0084] Optionally, an external force may be applied to the pressure receiving portion 211 by manual operation, or the battery cell 200 may apply an external force to the pressure receiving portion 211 .

[0085] Optionally, the rotating portion 212 may be configured as a rolling bearing, which is mounted on the base 10 .

[0091] Optionally, the pressure portion 211 and the clamping portion 213 may be fixedly connected to the rotating portion 212 by welding or bonding. Of course, they may also be fixedly connected to the rotating portion 212 by fasteners such as bolts and screws.

[0092] In other optional embodiments, the pressure-receiving portion 211 and the clamping portion 213 are both rotatably connected to the rotating portion 212, and the rotating portion 212 is fixedly connected to the base 10. This arrangement ensures that the pressure-receiving portion 211 and the clamping portion 213 can rotate synchronously relative to the base 10 via the rotating portion 212.

[0093] In some alternative embodiments, in the first direction X, the normal projection of the pressure receiving portion 211 and the normal projection of the clamping cavity 201 are arranged in an overlapping manner.

[0094] That is, the pressure receiving portion 211 can be arranged on the side of the clamping portion 213 facing the clamping cavity 201, so that the battery monomer 200 can provide an external force to the pressure receiving portion 211, and the locking member 21 can be triggered to rotate by the self-gravity of the battery monomer 200.

[0095] Specifically, when the battery monomer 200 is placed in the clamping cavity 201, when the battery monomer 200 presses against the pressure receiving portion 211, the pressure receiving portion 211 rotates relative to the base 10 through the rotating portion 212, and at the same time drives the clamping portion 213 to rotate to adjust the volume of the clamping cavity 201, so that it can clamp the battery monomer 200 to prevent it from shaking; when the battery monomer 200 is removed, the clamping portion 213 rotates relative to the base 10 in the opposite direction through the rotating portion 212 to adjust the volume of the clamping cavity 201, and at the same time drives the pressure receiving portion 211 to rotate to make them return to the initial position, in order to wait for the next rotation.

[0096] In this way, the pressure receiving portion 211 can receive the pressure provided by the battery monomer 200 to rotate relative to the base 10 through the rotating portion 212, that is, during the process of placing the battery monomer 200 into the transfer device 100, the locking mechanism 20 can adaptively rotate to adjust the volume of the clamping cavity 201, to ensure the close combination of the battery monomer 200 and the transfer device 100 during the transfer process, eliminate the inertial impact of the battery monomer 200 during the transfer process, more effectively solve the problem of the battery monomer 200 being injured, and the process is convenient to operate, which is also conducive to improving the transfer efficiency of the transfer device 100.

[0097] In some alternative embodiments, in the first direction X, the normal projection of the pressure receiving portion 211 and the normal projection of the clamping cavity 201 are arranged in an overlapping manner.

[0098] In this structure, the battery monomer 200 will not come into contact with the pressure receiving portion 211 during the process of being placed into the clamping cavity 201, so that an external force can be applied to the pressure receiving portion 211 by manual operation.

[0099] In some alternative embodiments, the locking mechanism 20 and the base 10 can be switched between a first cooperation position and a second cooperation position. In the first cooperation position, the clamping portion 213 and the bearing surface 101 have a first included angle, and the clamping cavity 201 has a first normal projection area in the first direction X. In the second cooperation position, the clamping portion 213 and the bearing surface 101 have a second included angle, and the clamping cavity 201 has a second normal projection area in the first direction X, the second normal projection area is smaller than the first normal projection area, and the second included angle is greater than the first included angle.

[0100] The locking member 21 can rotate relative to the base 10 about an axis in a direction intersecting the first direction X, so that the locking mechanism 20 and the base 10 can switch between the first mating position and the second mating position.

[0101] like Figure 1 As shown, the first matching position can be understood as the positional relationship between the locking mechanism 20 and the base 10 when the transport device 100 does not carry the battery cell 200; Figure 3 As shown, the second mating position can be understood as the positional relationship between the locking mechanism 20 and the base 10 when the transfer device 100 carries the battery cell 200 .

[0102] The first angle can be understood as the angle between the side surface of the clamping portion 213 facing away from the clamping cavity 201 and the bearing surface 101 in the first mating position; the second angle can be understood as the angle between the side surface of the clamping portion 213 facing away from the clamping cavity 201 and the bearing surface 101 in the second mating position.

[0103] The first orthographic projection area can be understood as the projection area of ​​the clamping cavity 201 in the first direction X in the first mating position; the second orthographic projection area can be understood as the projection area of ​​the clamping cavity 201 in the first direction X in the second mating position;

[0104] The second angle is greater than the first angle, and the second orthographic projection area is smaller than the first orthographic projection area. It can be understood that in the second mating position, the clamping portion 213 is closer to the clamping cavity 201 than in the first mating position, that is, in the process of switching from the first mating position to the second mating position, the clamping portion 213 rotates toward the clamping cavity 201.

[0105] By configuring in the above manner, the clamping portion 213 can rotate toward the battery cell 200 , so that the locking mechanism 20 can better clamp the battery cell 200 to prevent it from shaking.

[0106] Please also refer to Figures 1 to 4 In some optional embodiments, at the first mating position, at least a portion of the pressed portion 211 protrudes from the bearing surface 101 along the first direction X, and at the second mating position, the pressed portion 211 extends into the interior of the base 10.

[0107] By setting it up in this way, the pressure-bearing portion 211 can effectively receive the pressure provided by the battery cell 200, and the battery cell 200 can press the pressure-bearing portion 211 to the inside of the base 10, so that the battery cell 200 can abut against the supporting surface 101 of the base 10, thereby increasing the supporting area of ​​the base 10 for the battery cell 200, making the battery cell 200 more stable during transportation.

[0108] Optionally, in the first engagement position, the pressure receiving portion 211 is partially located in the groove 102 to be connected with the rotating portion 212, and the other part protrudes from the bearing surface 101, and in the second engagement position, the pressure receiving portion 211 is entirely inserted into the groove 102.

[0109] Optionally, the clamping portion 213 is partially located in the groove 102 to be connected with the rotating portion 212, and the other part protrudes from the bearing surface 101 to form the clamping cavity 201.

[0110] Please refer to Figure 5 In some optional embodiments, the clamping portion 213 includes clamping bodies 2131 and counterweight components 2132, each clamping body 2131 forms the clamping cavity 201, the clamping body 2131 and the pressure receiving portion 211 are intersected and connected to the rotating portion 212, and the counterweight component 2132 is arranged on the side of the clamping body 2131 away from the clamping cavity 201.

[0111] Specifically, at least part of each clamping body 2131 protrudes from the bearing surface 101 in the first direction X and forms the clamping cavity 201.

[0112] The counterweight component 2132 is used to provide traction for the clamping body 2131, and the weight of the counterweight component 2132 is greater than the weight of the pressure receiving portion 211, that is, when the pressure receiving portion 211 loses external force, due to the larger weight of the counterweight component 2132, the clamping body 2131 will be automatically pulled to rotate to drive the pressure receiving portion 211 to rotate.

[0113] In this way, the effectiveness of the clamping portion 213 driving the pressure receiving portion 211 to rotate together is met.

[0114] For example, the pressure receiving portion 211 is arranged on the side of the clamping body 2131 facing the clamping cavity 201, and the counterweight component 2132 is arranged on the side of the clamping body 2131 away from the clamping cavity 201.

[0115] Specifically, in the first engagement position, the counterweight component 2132 has a first minimum gap value with the bearing surface 101 in the first direction X, and the counterweight component 2132 can abut against the bearing surface 101, and in the second engagement position, the counterweight component 2132 has a second minimum gap value with the bearing surface 101 in the first direction X, and the second minimum gap value is greater than the first minimum gap value.

[0116] In some optional embodiments, the counterweight component 2132 is detachably connected to the clamping body 2131.

[0117] In this way, the locking piece 21 can be replaced with different specifications of the counterweight component 2132, which is beneficial to improve the use flexibility of the transfer device 100.

[0118] Optionally, the counterweight component 2132 can be detachably connected to the clamping body 2131 by, but not limited to, fasteners such as bolts, screws, etc.

[0119] Optionally, the clamping body 2131 can also be provided with a bracket, and the counterweight component 2132 can be arranged on the bracket.

[0120] In some optional embodiments, the pressure receiving part 211 is arranged in connection with the clamping part 213, and the rotating part 212 is arranged at the intersection of the pressure receiving part 211 and the clamping part 213.

[0121] In this way, the layout is reasonable, and the assembly is facilitated, which is beneficial to improve the manufacturing efficiency.

[0122] In some optional embodiments, the pressure receiving part 211 and the clamping part 213 are integrated structures.

[0123] In this way, the processing efficiency is improved, and the reliability of synchronous rotation of the two is also improved.

[0124] Please continue to refer to Figure 5 In some optional embodiments, the locking member 21 further includes an elastic part 214, and at least one of the pressure receiving part 211 and the clamping part 213 is provided with the elastic part 214 on the side facing the clamping cavity 201.

[0125] The elastic part 214 refers to a structure that can deform under pressure. The elastic part 214 can include, but is not limited to, structures such as rubber, foam, and silicone pad.

[0126] The transport device 100 provided by some embodiments of the present application can prevent the battery monomer 200 from colliding by arranging the elastic part 214 when the locking member 21 clamps the battery monomer 200. In addition, the elastic part 214 can also provide friction for the battery monomer 200 to eliminate the gap between the battery monomer 200 and the transport device 100, prevent the battery monomer 200 from frequently colliding with the transport device 100 during the transport process, and facilitate the limiting and clamping effect of the locking member 21 on the battery monomer 200.

[0127] For example, the pressure receiving part 211 and the clamping part 213 are both provided with the elastic part 214 on the side facing the clamping cavity 201.

[0128] For example, the pressure receiving part 211 and the clamping part 213 are both provided with the elastic part 214 on the side facing the clamping cavity 201. Figure 5As shown, in some optional embodiments, a resilient portion 214 is provided on a side of the clamping portion 213 facing the clamping cavity 201, and an angle is formed between a surface of the resilient portion 214 facing away from the clamping portion 213 and a surface of the clamping portion 213 facing the resilient portion 214. The surface of the resilient portion 214 facing away from the clamping portion 213 has a first end 2141 and a second end 2142 along the first direction X, and the minimum distance between the resilient portion 214 and the first end 2141 is smaller than the minimum distance between the resilient portion 214 and the second end 2142.

[0129] “There is an angle between the side surface of the elastic portion 214 facing away from the clamping portion 213 and the side surface of the clamping portion 213 facing the elastic portion 214” means that the side surface of the elastic portion 214 facing away from the clamping portion 213 is inclined to the side surface of the clamping portion 213 facing the elastic portion 214. The side surface of the clamping portion 213 facing the elastic portion 214 can be understood as the side surface of the elastic portion 214 facing the clamping portion 213, that is, the elastic portion 214 can be an elastic component with uneven thickness.

[0130] “The minimum distance between the elastic portion 214 and the first end 2141 is smaller than the minimum distance between the elastic portion 214 and the second end 2142 ” can be understood as that the thickness of the elastic portion 214 at the first end 2141 is smaller than the thickness at the second end 2142 .

[0131] When the battery cell 200 is placed in the clamping cavity 201, the first end 2141 of the elastic portion 214 arranged on the clamping portion 213 is close to the bottom surface of the battery cell 200, and the second end 2142 is close to the top surface of the battery cell 200. By setting the thickness of the elastic portion 214 at the second end 2142 to be greater than the thickness of the first end 2141, the battery cell 200 and the first end 2141 of the elastic portion 214 are more tightly abutted, which can prevent the battery cell 200 from shaking in the second direction Y or the third direction Z, and can also limit the shaking of the battery cell 200 in the first direction X.

[0132] By configuring in this manner, the friction between the elastic portion 214 and the battery cell 200 can be better increased, thereby improving the limiting and clamping effect of the locking member 21 on the battery cell 200 .

[0133] Optionally, the thickness of the elastic portion 214 increases from the first end 2141 to the second end 2142 .

[0134] like Figure 5 As shown, in some optional embodiments, the pressed portion 211 is a straight structure, and the clamping portion 213 is a straight structure.

[0135] Such a design facilitates the processing and manufacturing of the locking member 21 and helps to improve the manufacturing efficiency.

[0136] The pressure receiving part 211 is in a flat structure, and the upper surface of the pressure receiving part 211 can be in close contact with the lower surface of the battery monomer 200, so as to meet the requirement of the battery monomer 200 on the pressure receiving part 211.

[0137] The clamping part 213 is in a flat structure, which can prevent the battery monomer 200 from interfering with the clamping cavity 201 during the process of being placed in the clamping cavity 201, so as to avoid the battery monomer 200 from being scratched and affecting the quality.

[0138] In some optional embodiments, the pressure receiving part 211 is in a flat structure, and the clamping part 213 is in an arc structure, and the clamping part 213 is recessed to the side away from the pressure receiving part 211.

[0139] By setting the clamping part 213 in an arc structure, when the battery monomer 200 is placed in the clamping cavity 201, the clamping part 213 can be in abutment with the side surface of the battery monomer 200 and the upper surface along the first direction X, which can not only limit the horizontal movement of the battery monomer 200 in the second direction Y or the third direction Z, but also limit the vertical movement of the battery monomer 200 in the first direction X, so as to better prevent the battery monomer 200 from shaking.

[0140] Optionally, the side surface of the clamping part 213 towards the pressure receiving part 211 is in a shape corresponding to the side surface of the battery monomer 200, so that the two can be in closer contact.

[0141] Some embodiments of the application provide a transfer device 100, which is set in the above manner, and is beneficial to improving the use flexibility of the locking part 21.

[0142] Optionally, the pressure receiving part 211 is in a flat structure, the clamping part 213 is in a flat structure, and the pressure receiving part 211 and the clamping part 213 are both provided with an elastic part 214, the elastic part 214 provided on the clamping part 213 has a first end 2141 and a second end 2142 along the first direction X, the first end 2141 is set towards the rotating part 212, and the second end 2142 is set away from the rotating part 212, and the thickness of the elastic part 214 has a trend of increasing from the first end 2141 to the second end 2142.

[0143] Please refer to Figure 1 Stage Figure 3 In some optional embodiments, the transfer device 100 further comprises a limiting part 30, the limiting part 30 is provided on the base 10 and at least partially protrudes from the bearing surface 101 along the first direction X, the limiting part 30 is distributed in space with each locking part 21, and the limiting part 30 and each locking part 21 jointly enclose the clamping cavity 201.

[0144] The limiting member 30 can be used together with the locking member 21 to limit the battery monomer 200, further improve the limiting effect of the battery monomer 200, and better prevent the battery monomer 200 from shaking and colliding with the transfer device 100 during the transfer process. In addition, the limiting member 30 can also provide positioning effect to facilitate the placement of the battery monomer 200.

[0145] Optionally, the limiting member 30 is connected to the bearing surface 101, so that the limiting member 30 is at least partially protruding from the bearing surface 101 in the first direction X; or the limiting member 30 can also be provided by inserting the bearing surface 101 into the base 10, so that part of the limiting member 30 is at least partially protruding from the bearing surface 101 in the first direction X.

[0146] Optionally, the limiting member 30 can include but is not limited to limiting columns, limiting plates and the like.

[0147] It can be understood that the limiting member 30 does not have the function of rotating relative to the base 10 as the locking member 21, so that by setting the limiting member 30 in combination with the locking member 21, the number of locking members 21 can be reduced to reduce the cost.

[0148] In some embodiments, the limiting member 30 is movably connected to the base 10 to adjust the size of the clamping cavity 201, so that the transfer device 100 can be suitable for battery monomers 200 of different specifications. Among them, the limiting member 30 can be movably connected to the base 10 through a sliding rail, a sliding block or the like

[0149] In another embodiment, the limiting member 30 is fixedly connected to the base 10, which can reduce the processing cost and also reduce the maintenance cost.

[0150] In the above technical solution, the limiting member 30 is used together with the locking member 21 to limit the limiting effect, which is beneficial to reduce the cost.

[0151] In some optional embodiments, the number of limiting members 30 is at least two, and the at least two limiting members 30 are arranged at intervals.

[0152] By this way, the clamping effect of the battery monomer can be further improved to make it stably placed on the transfer device 100 without shaking.

[0153] Please refer to Figure 3In some optional embodiments, the base 10 has a clamping groove 103 formed by the bearing surface 101 being recessed inward, and the clamping groove 103 extends along the second direction Y. Locking members 21 and limiting members 30 are provided on both sides of the clamping groove 103 along the third direction Z. In the third direction Z, the minimum distance between at least one limiting member 30 and the clamping groove 103 is greater than the minimum distance between the locking member 21 and the clamping groove 103, and the first direction X, the second direction Y and the third direction Z are intersected.

[0154] The clamping groove 103 is used for the clamping claws on the production line to grab the battery cell 200. When the transfer device 100 transfers the battery cell 200 to the corresponding position, the clamping claws are used to take out the battery cell 200 and put it into the next device.

[0155] The clamping claw groove 103 may be provided along the second direction Y to pass through the base 10 , or may not pass through the base 10 .

[0156] The clamping groove 103 extends along the second direction Y to provide operating space for the clamping jaw. It can be understood that after the battery cell 200 is placed on the transfer device 100, its tab 210 can be located on one side or both sides of the battery cell 200 along the third direction Z to avoid interference with the clamping jaw, so that the clamping jaw can clamp the battery cell 200 on both sides along the second direction Y without damaging the tab 210.

[0157] It can be understood that when the battery cell 200 is placed on the transfer device 100, the locking member 21 is in motion. If it is set at a position close to the pole ear 210, it may collide with the pole ear 210. Therefore, by setting the minimum distance between at least one limiting member 30 and the clamping groove 103 along the third direction Z to be greater than the minimum distance between the locking member 21 and the clamping groove 103 along the third direction Z, that is, setting the limiting member 30 at a position close to the pole ear 210, the layout is reasonable, which can not only play a role in positioning and limiting the battery cell 200, but also prevent the pole ear 210 from being collided, thereby helping to improve the qualified rate of the battery cell 200.

[0158] For example, Figure 3 As shown, the number of locking members 21 can be set to four, the number of limiting members 30 can be set to eight, and the shape of each limiting member 30 can be designed according to different layout spaces.

[0159] Optionally, the base 10 has a groove 102 and a clamping groove 103 formed by the bearing surface 101 being recessed inward, the groove 102 and the clamping groove 103 are spaced apart, and part of the locking member 21 is disposed in the groove 102 to be rotatably connected to the base 10 .

The pressure receiving part 211 and the clamping part 213 are provided with elastic parts 214 on one side facing the clamping cavity 201.

[0164] The clamping part 213 comprises a clamping body 2131 and a counterweight component 2132 connected detachably, at least part of each clamping body 2131 protrudes from the bearing surface 101 along the first direction X and encloses to form the clamping cavity 201, the counterweight component 2132 is arranged on the side of the clamping body 2131 away from the clamping cavity 201, the clamping body 2131 and the pressure receiving part 211 are arranged at the intersection and are fixedly connected to the rotating part 212, and in the first direction X, the orthographic projection of the pressure receiving part 211 and the orthographic projection of the clamping cavity 201 are arranged in overlapping manner. The pressure receiving part 211 is configured to receive external force to drive the clamping part 213 to rotate relative to the base 10 through the rotating part 212 with the direction intersecting the first direction X as the axis, and the clamping part 213 is configured to drive the pressure receiving part 211 to rotate relative to the base 10 through the rotating part 212 with the direction intersecting the first direction X as the axis when the pressure receiving part 211 loses external force, so as to adjust the size of the orthographic projection area of the clamping cavity 201 in the first direction X.

[0165] The locking mechanism 20 and the base 10 can be switched between a first cooperation position and a second cooperation position. In the first cooperation position, at least part of the pressure-receiving portion 211 protrudes from the bearing surface 101 in the first direction X, the pressure-receiving portion 211 and the bearing surface 101 have a first included angle, and the clamping cavity 201 has a first orthogonal projection area in the first direction X.
