Description

Technical Field

[0001] The present invention relates to the field of battery technology, and in particular to a support pushing system and a pushing method. Background Art

[0002] For wound cells, a center hole will be formed inside the core after the winding needle is removed. During the subsequent manufacturing and recycling of the battery, the core may be deformed due to the gap in the center hole, and the center area is prone to collapse, deformation, or even breakage, affecting the normal use of the battery.

[0003] In order to improve the above defects, in the prior art, the general practice is to insert a support into the center hole of the core to support the inside of the core and prevent the center of the core from collapsing and deforming. At the same time, in order to ensure that the support can just rest against the hole wall of the center hole of the core, the outer dimensions of the support need to be very close to the center hole size of the core. However, due to objective factors such as the processing and manufacturing errors of the supports, the processing and manufacturing tolerances of some supports are out of range, and the consistency of the supports is low, which ultimately makes it difficult to insert the supports into the center hole; or when forcibly inserted into the center hole, it is easy to damage the diaphragm and pole piece, causing the core to be scrapped. Summary of the invention

[0004] In order to solve at least one problem existing in the above-mentioned prior art, according to a first aspect of the present invention, a support pushing system is provided, which is used to push the support toward the central hole of the winding core, comprising:

[0007] The moving device is connected to the opening and closing device or the winding core to drive the opening and closing device or the winding core to move relative to each other in the pushing direction of the pushing device, so as to achieve the approach or distance between the opening and closing device and the winding core.

[0008] In some embodiments, the support pushing system also includes a guide member, the opening and closing device is connected to the guide member, and the opening and closing device and the pushing device are located on opposite sides of the guide member along the pushing direction, and the guide member has a hole portion, and the central axis of the hole portion, the central axis of the pushing port, and the central axis of the central hole of the winding core coincide with each other.

[0009] In some embodiments, the support pushing system includes a feeding device, which is used to place the supports and push the supports one by one to the feeding device.

[0010] In some embodiments, the support pushing system further includes a support table;

[0011] The support platform is arranged in the pushing direction of the pushing device and is located at the front end of the guide member along the pushing direction, and is used to support the support delivered by the feeding device.

[0012] In some embodiments, the feeding device includes a lifting mechanism and a silo, the lifting mechanism is arranged at the bottom of the silo; the silo has an inclined wall and a vertical wall arranged relative to each other, the inclined wall is arranged to be inclined downward, and the lifting mechanism is arranged close to the vertical wall, and is used to push the supports one by one to move upward along the wall surface of the vertical wall to separate from the silo.

[0013] In some embodiments, the lifting mechanism has a pushing inclined surface, and the pushing inclined surface is arranged to be inclined downward relative to the vertical wall.

[0014] In some embodiments, the support pushing system further includes a guide platform, which is arranged obliquely downward from the opening end of the silo and connected to the support platform, so as to allow the support pushed out by the lifting mechanism to slide to the support platform.

[0015] In some embodiments, when the plurality of opening and closing pieces are in a closed state, each of the opening and closing pieces and the pushing direction have an angle θ, and the angle θ is an acute angle, and the range of the angle θ is 20-80°.

[0016] In some embodiments, the support pushing system further includes a position detection device, which is disposed on opposite sides of the winding core along the pushing direction and the pushing device, and is used to detect the pushing position of the support in the winding core.

[0017] The first aspect of the present invention provides a method for pushing a support, comprising: a moving device drives an opening and closing device to move toward a winding core, or drives the winding core to move toward the opening and closing device, so that a plurality of opening and closing pieces in a closed state are inserted into the center hole of the winding core; an opening and closing driving mechanism drives a plurality of opening and closing pieces to open to form a pushing port; a pushing device pushes the support to pass through the pushing port and enter into the center hole; the moving device drives the opening and closing device to move in a direction away from the winding core, or drives the winding core to move in a direction away from the opening and closing device; the opening and closing driving mechanism drives a plurality of opening and closing pieces to close to form a pointed end.

[0018] In summary, the fully liquid-cooled cooling system, battery pack and automobile provided by the present invention have the following technical effects:

At this time, it is convenient for the pushing device to push the support to pass through the pushing port and enter the winding core. Since the multiple opening and closing pieces are opened from the conical closed state, the outer diameter of the cone is small and has a guiding function, it is easier to insert into the center hole of the winding core, avoiding damage to the winding core. At the same time, under the guiding effect of the opening and closing pieces, the support can quickly enter the winding core, thereby improving production efficiency.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 3 , a support pushing system 100 provided in an embodiment of the present invention is used to push a support 200 toward a central hole 310 of a winding core 300, and includes a pushing device 10, an opening and closing device 20, and a moving device 30.

[0029] Among them, the pushing device 10 is used to push the support 200 into the central hole 310 of the winding core 300; the opening and closing device 20 is arranged on one side of the pushing device 10, including an opening and closing drive mechanism (not shown in the figure) and a plurality of opening and closing plates 22, the opening and closing drive mechanism is used to drive the plurality of opening and closing plates 22 to open to form or close a pushing port 23, so that when the pushing port 23 is formed, the support 200 driven by the pushing device 10 can pass through, so that the support 200 enters the central hole 310, wherein the plurality of opening and closing plates 22 are conical in the closed state, and the conical tip 24 faces the winding core 300; the moving device 30 is connected to the opening and closing device 20 or the winding core 300, so as to be able to drive the opening and closing device 20 or the winding core 300 to move relative to each other in the pushing direction a of the support 200, so as to realize the approach or distance between the pushing device 10 and the winding core 300.

[0030] The above-mentioned support pushing system 100, when pushing the support 200 into the winding core 300, realizes the approach or distance between the opening and closing device 20 and the winding core 300 through the moving device 30. When the opening and closing device 20 and the winding core 300 are close, the tips 24 of the multiple opening and closing pieces 22 in the closed state and in a cone shape can be easily inserted into the end of the center hole 310, and then the multiple opening and closing pieces 22 are driven to open by the opening and closing driving mechanism to form a pushing port 23. At this time, it is convenient for the pushing device 10 to push the support 200 through the pushing port 23 and then enter the winding core 300. Since the multiple opening and closing pieces 22 are opened again from the conical closed state, the outer diameter is small when conical and has a guiding function, it is easier to insert them into the center hole 310 of the winding core 300, avoiding damage to the winding core 300. At the same time, under the guiding function of the opening and closing pieces 22, the support 200 can quickly enter the winding core 300, thereby improving production efficiency.

[0031] In this embodiment, the cylindrical winding core 300 is pushed into the support 200, and the support 200 is also circular. In other embodiments, the shape of the support can be set according to the shape of the winding core. For example, when the winding core is square, the support can be set in a square shape.

[0032] In one embodiment, when the support 200 is pushed, the pushing device 10 can be set as a cylinder, and a clamping claw is set on the piston shaft of the cylinder, and the clamping claw can clamp the support. When the opening and closing device 20 is in an open state to form a push port 23, the cylinder can drive the support 200 to pass through the push port 23 and enter the central hole 310 of the winding core 300. In another embodiment, the pushing device 10 can be set in the form of a driving motor, a screw rod, a movable block and a clamping claw, the screw rod is connected to the driving motor, the movable block and the screw rod are rotatably arranged, the clamping claw is connected to the movable block, and is used to clamp the support 200, so that under the drive of the motor, the clamping claw clamps the support 200 and passes through the push port 23, and then pushes the support 200 into the winding core 300.

[0033] Further, when an opening and closing device 20 is provided, in one embodiment, the opening and closing driving mechanism can be provided as an opening and closing cylinder, on which two relatively arranged semi-conical opening and closing pieces 22 are provided, and under the drive of the opening and closing cylinder, the opening and closing of the two semi-conical opening and closing pieces 22 are realized; in another embodiment, when a plurality of opening and closing pieces 22 are provided, for example, the opening and closing of the umbrella frame is realized by a connecting rod driving method disclosed in the document with publication number CN116088250A, or in another embodiment, the opening and closing of the plurality of opening and closing pieces 22 is driven by a gear matching method as disclosed in the document with publication number CN215705880U, both of which can achieve the effect of driving the plurality of opening and closing pieces 22 to open and close, and the choice of the opening and closing driving mechanism is not limited here.

[0034] It can be understood that the plurality of opening and closing pieces 22 of the present embodiment can be set to at least two pieces, or can be three pieces, four pieces, five pieces or more, which is not limited here, as long as they can be opened and closed in coordination with the structure of the opening and closing drive mechanism.

[0035] For further information, see Figure 3 When the multiple opening and closing pieces 22 are in the closed state, each opening and closing piece 22 and the pushing direction a have an angle θ, which is an acute angle, and the range of the angle θ is 20-80°. By setting the angle θ, when the multiple opening and closing pieces 22 are transformed from the closed state to the open state, the caliber of the push opening 23 formed by the opening can be guaranteed. If the angle is set to be less than 20°, the caliber of the push opening 23 formed by the opening of the opening and closing pieces 22 may not be large enough to match the diameter of the support; if the angle is set to be greater than 80 degrees, when the opening and closing pieces 22 are in the open state, the guiding effect on the support 200 is reduced. Setting the angle θ within the range of 20-80° can not only take into account the diameter of the support 200, but also guide the movement of the support 200, and avoid excessive deviation from the center hole 310 of the winding core 300 when the support 200 moves away from the push opening 23.

[0036] In some embodiments, the angle θ can be set to values ​​such as 20°, 30°, 40°, 50°, 60°, 70° or 80°, which is not limited here.

[0037] See also Figure 1 and Figure 2In one embodiment of the present invention, in order to ensure that the pushing device 10 can align with the central axis of the central hole 310 of the winding core 300 when pushing the support 200, the support pushing system 100 also includes a guide member 40, the opening and closing device 20 is connected to the guide member 40, and the opening and closing device 20 and the pushing device 10 are located on opposite sides of the guide member 40 along the pushing direction a, the guide member 40 has a hole portion 41, the central axis of the hole portion 41, the central axis of the pushing port 23 and the central axis of the central hole 310 of the winding core 300 coincide, and the pushing device 10 pushes the support 200 to pass through the hole portion 41 and the pushing port 23 in sequence. In this way, a guide member 40 is also provided between the pushing device 10 and the winding core 300. When the pushing device 10 moves with the support 200 in the direction of the winding core 300, it first passes through the hole portion 41 of the guide member 40, passes through the correction effect of the guide member 40, and then is pushed into the central hole 310 of the winding core 300 to ensure the accuracy when inserting the support 200.

[0038] The hole portion 41 of the present embodiment is configured as a full hole, and the hole portion 41 is disposed in the central region of the guide member 40 and penetrates the guide member 40 along the pushing direction a.

[0039] Among them, when being set, the moving device 30 can be connected to the opening and closing device 20, or connected to a supporting device that supports the winding core 300. The driving moving direction of the moving device 30 is parallel to the pushing direction a of the pushing device 10, and is used to drive the relative approach or distance between the opening and closing device 20 and the winding core 300, so that when the opening and closing device 20 and the winding core 300 are close to each other, the conical tip 24 of the opening and closing device 20 can extend into the winding core 300, and after the support 200 is pushed in, the opening and closing device 20 and the winding core 300 can be moved away from each other.

[0040] Furthermore, in some embodiments, the moving device 30 can be configured as a linear module to achieve driving in a linear direction. Furthermore, since the opening and closing device 20 of this embodiment is connected to the guide member 40, when the linear module is connected to the opening and closing device 20, the linear module is arranged at the bottom of the guide member 40, and synchronously drives the guide member 40 and the opening and closing device 20 to move in the pushing direction a.

[0041] See also Figure 1 and Figure 2 In one embodiment of the present invention, in order to provide supports 200 to the pushing device 10 in an orderly manner, the support pushing system 100 includes a feeding device 50, which is used to place the supports 200 and push the supports 200 one by one to the feeding device 50. Through the setting of the feeding device 50, the supports 200 can be provided to the pushing device 1 in an orderly manner and one by one, thereby ensuring the connection of the production rhythm.

[0042] Furthermore, in order to be able to receive the supports 200 delivered by the feeding device 50, the support pushing system 100 also includes a support table 60; the support table 60 is arranged on the pushing direction a of the pushing device 10, and is located at the front end of the opening and closing device 20 along the pushing direction a, and is used to support the supports 200 delivered by the feeding device 50; since the feeding device 50 is used to place the supports 200 and push the supports 200 one by one to the support table 60, and the support table 60 is arranged in the pushing direction of the pushing device 10, the support table 60 supports the supports 200 delivered by the feeding device 50, and the pushing device 10 pushes the supports 200 located on the support table 60 through the opening and closing device 20, and finally pushes them into the winding core 300; through the support of the support table 60, the placement direction of the supports 200 can be preliminarily positioned.

[0043] Furthermore, in order to facilitate the placement of the support 200 , the support platform 60 is provided with a contoured groove 61 , the shape of which is adapted to the shape of the support 200 , thereby facilitating the limiting of the placement of the support 200 .

[0044] Specifically, on the basis of setting the guide member 40, a support platform 60 can be further set. Along the pushing direction a, the pushing device 10, the support platform 60, the guide member 40 and the opening and closing device 20 are sequentially set. The pushing device 10 pushes the support 200 on the support platform 60 through the guide member 40. After preliminary correction by the guide member 40, it passes through the pushing port 23 of the opening and closing device 20 and enters into the center hole 310 of the winding core 300.

[0045] Among them, when the feeding device 50 is set, in one embodiment, the feeding direction can be set perpendicular to the pushing direction a of the pushing device 10. The feeding device 50 can also be set as a driving cylinder, and the piston shaft of the driving cylinder is extended to push the supports 200 placed on the support plane one by one onto the support platform 60. In another embodiment, the feeding device 50 can be in the form of a motor, a screw rod and a push rod, and the rotation of the motor drives the screw rod to rotate, and the rotation of the screw rod drives the push rod to push the supports 200 onto the support platform 60.

[0046] For further information, see Figure 1 and Figure 2 In order to ensure the production rhythm, the feeding device 50 includes a lifting mechanism 51 and a silo 52. The lifting mechanism 51 is arranged at the bottom of the silo 52, and is used to push out the supports 200 in the silo 52 one by one in an upward manner. In this way, after the supports 200 are pushed into the winding core 300 one by one by the pushing device 10, the synchronous lifting mechanism 51 pushes the supports 200 one by one onto the support table 60, and the production rhythm is connected in sequence to ensure production efficiency.

[0047] The lifting mechanism 51 can be set as a driving cylinder, and the lifting mechanism 51 is set in the vertical direction. As the piston shaft of the driving cylinder is extended and retracted, the support 200 is pushed out of the silo 52 and moved onto the support platform 60. In other embodiments, the lifting mechanism 51 can also be set as a mechanism that can achieve linear drive when the motor screw rod cooperates.

[0048] Specifically, when the silo 52 is set, the silo 52 has an inclined wall 521 and a vertical wall 522 that are relatively set. The inclined wall 521 is set to be inclined downward, and the lifting mechanism 51 is set close to the vertical wall 522, which is used to push the supports 200 one by one to move upward along the wall surface of the vertical wall 522. Due to the setting of the inclined wall 521, as the supports 200 are pushed out one by one by the lifting mechanism 51, the supports 200 can rely on their own gravity to move downward, and move one by one in the direction of the vertical wall 522, and move to the top of the lifting mechanism 51, and the lifting mechanism 51 gradually lifts the supports 200 along the vertical wall 522, and finally rolls out from the opening of the silo 52.

[0049] The lifting mechanism 51 is disposed on the bottom wall 523 of the silo 52 , and the piston shaft can penetrate the bottom wall 523 , so that the support 200 can be lifted.

[0050] Further, the lifting mechanism 51 has a push slope 511, for example, a push block having a push slope 511 is provided at the end of the piston shaft, so that when the lifting mechanism 51 lifts the support 200 to the opening of the bin 52, the push slope 511 has a guiding effect on the support 200, and the object can move out of the bin 52 in the inclined direction of the push slope 511. It can be understood that there is an angle between the push slope 511 and the vertical wall 522 of this embodiment, and the angle is an acute angle.

[0051] See also Figure 1 and Figure 2 In one embodiment of the present invention, since the silo 52 has a certain setting height, it can accommodate the support 200. In order to facilitate the connection between the support 200 and the support platform 60 when it is pushed out of the silo 52, the support pushing system 100 also includes a guide platform 70. The guide platform 70 is set obliquely downward from the open end of the silo 52 and connected with the support platform 60. It is used for the support 200 pushed out by the jacking mechanism 51 to slide to the support platform 60. Therefore, through the setting of the guide platform 70, after the support 200 moves out of the silo 52, it can extend the guide platform 70 set obliquely downward to slide to the support platform 60, thereby ensuring the stability of the movement of the support 200, avoiding the occurrence of messy rolling, and realizing the connection of production.

[0052] For further information, see Figure 2In order to detect the pushing position of the support 200 in the winding core 300, the support pushing system 100 also includes a position detection device 80. The position detection device 80 is arranged on the opposite sides of the winding core 300 along the pushing direction a and the pushing device 10, and is used to detect the position of the support 200 in the winding core 300. In this way, the setting of the position detection device 80 can avoid the situation where the support 200 is pushed too far and exposed relative to the winding core 300.

[0053] The position detection device 80 can be set as a baffle, and when the support 200 is pushed to contact the baffle, it indicates that it is pushed into place; or the position detection device 80 can be set as a distance sensor to accurately detect the pushing position of the support 200 through the distance sensor.

[0054] See also Figure 2 The operation process of the support pushing system 100 of this embodiment is as follows:

[0055] (a) The supports 200 are temporarily stored in the silo 52 and pushed out one by one by the lifting mechanism 51. The supports 200 that have left the silo 52 roll along the guide platform 70 and onto the support platform 60, where they are received by the support platform 60;

[0056] (b) The moving device 30 drives the guide member 40 and the opening and closing device 20 to move toward the winding core 300. The tip formed by the plurality of opening and closing pieces 22 is inserted into the central hole 310 of the winding core 300. Under the push of the pushing device 10, the support 200 moves along the guide member 40.

[0057] (c) The opening and closing mechanism drives the opening and closing plate 22 to open to form a push opening 23, and the pushing device 10 pushes the support 200 through the push opening 23 and into the winding core 300;

[0058] (d) After the supporting objects 200 are inserted in sequence, the moving device 30 drives the guide member 40 and the opening and closing device 20 to return to their original positions, and the opening and closing piece 22 is closed at the same time.

[0059] In summary, the support pushing system 100 has the following advantages:

[0060] (1) Through the guiding effect of the opening and closing piece 22, the support 200 can be smoothly pushed into the winding core 300, avoiding damage to the winding core 300 by forcibly pushing the support 200;

[0061] (2) The push system of this embodiment can perform the push action synchronously with the actions of other process of the equipment, thus solving the pain point of needing to reserve a separate production rhythm;

[0062] (3) The support 200 can be pushed in at room temperature, thus avoiding quality problems such as short circuit of the battery cell caused by the need to heat the support 200 to form a hole in the prior art;

[0063] (4) The accuracy and efficiency of inserting the support 200 into the center hole 310 are improved, which greatly improves the process yield and product quality and increases the equipment capacity.

[0064] In another embodiment, the present invention further provides a method for pushing a support 200, comprising the following steps:

[0065] S21, the moving device 30 drives the opening and closing device 20 to move toward the winding core 300, or drives the winding core 300 to move toward the opening and closing device 20, so that the plurality of opening and closing pieces 22 in a closed state are inserted into the central hole 310 of the winding core 300;

[0066] S22, the opening and closing driving mechanism drives the plurality of opening and closing pieces 22 to open to form a push port 23;

[0067] S23, the pushing device 10 pushes the support 200 through the pushing port 23 and into the central hole 310

[0068] S24, the moving device 30 drives the opening and closing device 20 to move away from the winding core 300, or drives the winding core 300 to move away from the closing and opening device 20;

[0069] S25, the opening and closing driving mechanism drives the plurality of opening and closing pieces 22 to close to form a pointed end.

[0070] The pushing method of the above-mentioned support 200 is to set a plurality of opening and closing pieces 22 in a conical state when in the closed state, so that it can be smoothly inserted into the winding core 300, and then open a pushing port 23 to guide the pushing of the support 200, thereby improving the insertion efficiency of the support 200 and avoiding damage to the winding core 300.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
