Description

Technical Field

[0001] The present application relates to the technical field of battery processing equipment, and in particular to a pre-pressing device and a winding machine. Background Art

[0002] After the columnar battery cell is wound by the winding machine, there is a process of placing the columnar battery cell on a pre-pressing device and flattening it by the pre-pressing device. Specifically, the pre-pressing device usually includes an upper pressing plate and a lower pressing plate. When the columnar battery cell needs to be flattened, the columnar battery cell can be placed on the lower pressing plate first, and then the upper pressing plate is moved in a direction close to the lower pressing plate to clamp the columnar battery cell between the upper pressing plate and the lower pressing plate, so as to achieve the purpose of flattening the columnar battery cell.

[0003] Taking into account that there are certain requirements for the pressure on the columnar battery cells when flattening them, a pressure detection sensor for detecting the pressure on the columnar battery cells is usually additionally provided on the upper pressure plate. This method will lead to a complex structure of the pre-pressing device on the one hand, and a larger volume of the pre-pressing device on the other hand. Utility Model Content

Unless otherwise specified, "plurality" means two or more.

[0058] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0059] The present application provides a pre-pressing device 100, see Figure 1The prepressing device 100 includes a mounting frame 1 and a prepressing assembly 2, wherein the prepressing assembly 2 is arranged on the mounting frame 1, and the prepressing assembly 2 includes a first extrusion piece 21, a second extrusion piece 22 and an extrusion driving assembly 23, and the extrusion driving assembly 23 is used to drive at least one of the second extrusion piece 22 and the first extrusion piece 21 to move in a direction close to or away from the other, so as to clamp or release the piece A to be extruded between the first extrusion piece 21 and the second extrusion piece 22, wherein at least one of the first extrusion piece 21 and the second extrusion piece 22 is a pressure detection sensor, and the pressure detection sensor is used to detect the pressure exerted on the piece A to be extruded when it is clamped between the first extrusion piece 21 and the second extrusion piece 22.

[0060] In this embodiment, when the extruded piece A needs to be flattened, first, the extruded piece A can be placed between the second extrusion piece 22 and the first extrusion piece 21, and then, the extrusion drive assembly 23 can be used to drive at least one of the second extrusion piece 22 and the first extrusion piece 21 to move in a direction close to the other, so that the extruded piece A is clamped between the first extrusion piece 21 and the second extrusion piece 22, and the pressure on the extruded piece A gradually increases.

[0061] When the piece A to be extruded is clamped between the first extrusion piece 21 and the second extrusion piece 22, since at least one of the first extrusion piece 21 and the second extrusion piece 22 is a pressure detection sensor, the pressure on the piece A to be extruded can be detected by the first extrusion piece 21 and / or the second extrusion piece 22. When the pressure on the extrusion piece A meets the preset requirements, the extrusion drive component 23 can stop driving at least one of the second extrusion piece 22 and the first extrusion piece 21 to move in a direction close to the other. At the same time, the extrusion drive component 23 can drive at least one of the second extrusion piece 22 and the first extrusion piece 21 to move in a direction away from the other, so that the piece A to be extruded is released between the first extrusion piece 21 and the second extrusion piece 22. At this point, the purpose of flattening the piece A to be extruded can be achieved.

[0062] Among them, since at least one of the first extrusion member 21 and the second extrusion member 22 is a pressure detection sensor, the first extrusion member 21 and / or the second extrusion member 22 can not only play the role of extruding the piece A to be extruded, but also play the role of detecting the pressure exerted on the piece A to be extruded. In this way, the pressure detection sensor in the related technology can be replaced by the first extrusion member 21 or the second extrusion member 22. Therefore, on the one hand, the number of components of the pre-pressing device 100 can be reduced and the structure of the pre-pressing device 100 can be simplified. On the other hand, the volume of the pre-pressing device 100 can also be reduced.

[0063] The part A to be extruded may be a cylindrical battery cell or other possible components, which is not limited in this embodiment.

[0064] In some embodiments, see Figure 1 The first extrusion member 21 is fixedly arranged on the mounting frame 1, and the second extrusion member 22 is slidably arranged on the mounting frame 1 along a direction approaching or moving away from the first extrusion member 21. The extrusion driving assembly 23 is arranged on the mounting frame 1 and connected to the second extrusion member 22, and is used to drive the second extrusion member 22 to move along a direction approaching or moving away from the first extrusion member 21, wherein the first extrusion member 21 is a pressure detection sensor, and the second extrusion member 22 is a pressure plate.

[0065] Since the first extrusion member 21 is fixedly arranged on the mounting frame 1, and the second extrusion member 22 is slidably arranged on the mounting frame 1 along the direction approaching or moving away from the first extrusion member 21, and since the first extrusion member 21 is a pressure detection sensor and the second extrusion member 22 is a pressure plate, the pressure detection sensor will be fixedly arranged on the mounting frame 1, and the pressure plate will be slidably arranged on the mounting frame 1 along the direction approaching or moving away from the first extrusion member 21. With such an arrangement, it is possible to clamp or release the extruded member A between the first extrusion member 21 and the second extrusion member 22, while avoiding the pressure detection sensor from moving along the direction approaching or moving away from the pressure plate, thereby avoiding or reducing the possibility of damage to the pressure detection sensor during the movement, thereby making the pre-pressing device 100 more durable and more reliable.

[0066] When the second extrusion member 22 is a pressure plate, only the first extrusion member 21 of the first extrusion member 21 and the second extrusion member 22 can be a pressure detection sensor. Compared with the method in which both the first extrusion member 21 and the second extrusion member 22 are pressure detection sensors, the cost of the pre-pressing device 100 can be further reduced on the basis of being able to detect the pressure to be borne by the extruded member A.

[0067] Among them, see Figure 1 , the pressure detection sensor may be a plate-type pressure detection sensor. When the pressure detection sensor is a plate-type pressure detection sensor, its shape is more conducive to cooperating with the second extrusion member 22 to extrude the to-be-extruded piece A. Of course, the pressure detection sensor may also be other possible sensors, as long as it can cooperate with the second extrusion member 22 to extrude the to-be-extruded piece A and detect the pressure on the to-be-extruded piece A. This embodiment does not limit the pressure detection sensor.

[0068] It should be noted that see Figure 1 The second extrusion member 22 can be slidably disposed on the mounting frame 1 along a direction approaching or away from the first extrusion member 21 through a slide rail assembly 24, or can be slidably disposed on the mounting frame 1 along a direction approaching or away from the first extrusion member 21 through other methods, and this embodiment is not limited to this.

[0069] Considering that after the extruded part A is released between the first extruded part 21 and the second extruded part 22, the extruded part A may be adhered to the second extruded part 22, in some embodiments, see Figure 1 and Figure 2 The second extrusion piece 22 is provided with a blowing hole 222 for blowing air toward the piece A to be extruded.

[0070] By providing the blowing holes 222 , since air can be blown toward the piece A to be extruded through the blowing holes 222 , it is possible to prevent the piece A to be extruded from adhering to the second extrusion piece 22 .

[0071] The shape of the blowing hole 222 can be circular or square, etc., which is not limited in this embodiment. The number of the blowing holes 222 can be multiple, and the multiple blowing holes 222 can be arranged in an array on the second extrusion member 22, so that the extrusion member A can be better prevented from adhering to the second extrusion member 22.

[0072] In some embodiments, see Figure 1 , the first extrusion member 21 is arranged in the vertical direction ( Figure 1 The first extrusion member 21 is located below the second extrusion member 22 in the Z-axis direction. The first extrusion member 21 is also used to support the part A to be extruded.

[0073] By making the first extrusion piece 21 be located below the second extrusion piece 22 in the vertical direction, when the piece A to be extruded needs to be flattened, the piece A to be extruded can be placed on the first extrusion piece 21. In addition to cooperating with the second extrusion piece 22 to extrude the piece A to be extruded and detecting the pressure on the piece A to be extruded, the first extrusion piece 21 can also support the piece A to be extruded and provide a placement table for the piece A to be extruded. The first extrusion piece 21 has multiple uses and is very versatile, which can simplify the structure of the pre-pressing device 100.

[0074] Of course, in other embodiments, the first extrusion component 21 may also be located above the second extrusion component 22 in the vertical direction, which is not limited in this embodiment.

[0075] In addition, when the first extrusion component 21 is located below the second extrusion component 22 in the vertical direction, the first extrusion component 21 and the second extrusion component 22 are arranged in the vertical direction. Of course, in other embodiments, the first extrusion component 21 and the second extrusion component 22 may also be arranged in the horizontal direction. This embodiment does not limit the arrangement direction of the first extrusion component 21 and the second extrusion component 22.

[0076] In some embodiments, see Figure 3 and Figure 4The extrusion drive assembly 23 includes: an extrusion drive member 231 and a screw mechanism 232, wherein the screw mechanism 232 is arranged on the mounting frame 1, the extrusion drive member 231 is connected to the screw mechanism 232, the screw mechanism 232 is connected to the second extrusion member 22, and the extrusion drive member 231 is used to drive the second extrusion member 22 to move in a direction close to or away from the first extrusion member 21 through the screw mechanism 232.

[0077] Since the screw mechanism 232 is connected to the second extrusion member 22, and the extrusion driving member 231 is connected to the screw mechanism 232, the extrusion driving member 231 can drive the second extrusion member 22 to move in a direction close to or away from the first extrusion member 21 through the screw mechanism 232, thereby achieving the purpose of clamping or loosening the extruded member A between the first extrusion member 21 and the second extrusion member 22.

[0078] Since the screw mechanism 232 has the ability to convert rotational motion into linear motion, when the extrusion drive member 231 is a motor, the screw mechanism 232 can convert the rotational motion of the motor into linear motion of the second extrusion member 22 moving in a direction close to or away from the first extrusion member 21.

[0079] It can be seen that by arranging the screw mechanism 232 between the extrusion drive member 231 and the second extrusion member 22, the extrusion drive member 231 can select a more common motor that outputs rotational motion as the extrusion drive member 231, making the selection of the extrusion drive member 231 relatively simple.

[0080] In some embodiments, see Figure 3 , Figure 4 and Figure 5 The screw mechanism 232 includes: a transmission nut 2321 and a screw rod 2322, wherein the transmission nut 2321 is rotatably disposed on the mounting frame 1, the extrusion driving member 231 is used to drive the transmission nut 2321 to rotate, and the screw rod 2322 is threadedly connected to the transmission nut 2321 and moves along the moving direction of the second extrusion member 22 ( Figure 5 Z axis direction), see Figure 4 and Figure 5 The second extrusion member 22 is connected to the screw rod 2322 and a rotation-stopping portion 23221 is provided between the second extrusion member 22 and the screw rod 2322 . The rotation-stopping portion 23221 is used to prevent the screw rod 2322 from rotating relative to the second extrusion member 22 around its own axial direction.

[0081] In this embodiment, since the driving nut 2321 is rotatably disposed on the mounting frame 1, the screw rod 2322 is threadedly connected to the driving nut 2321 and extends along the moving direction of the second extrusion member 22, the second extrusion member 22 is connected to the screw rod 2322, and a stopper 23221 is provided between the second extrusion member 22 and the screw rod 2322. Since the second extrusion member 22 is slidably disposed on the mounting frame 1 in a direction approaching or away from the first extrusion member 21, when the extrusion drive member 231 drives the driving nut 2321 to start rotating, under the limiting action of the second extrusion member 22 and the stopper 23221, the screw rod 2322 cannot rotate with the driving nut 2321, but can only rotate along the extension direction of the screw rod 2322 ( Figure 5 The second extrusion component 22 is moved in the Z-axis direction, thereby driving the second extrusion component 22 provided on the screw rod 2322 to move along the extension direction of the screw rod 2322, thereby achieving the purpose of driving the second extrusion component 22 to move in the direction close to or away from the first extrusion component 21.

[0082] There are many ways to rotatably arrange the driving nut 2321 on the mounting frame 1. In one possible implementation, see Figure 5 The driving nut 2321 may be sleeved with a rotating shaft 2323, and the rotating shaft 2323 may be rotatably disposed on the mounting frame 1 via a bearing 2324, thereby achieving the purpose of rotatably disposing the driving nut 2321 on the mounting frame 1.

[0083] Of course, the transmission nut 2321 may also be rotatably disposed on the mounting frame 1 in other ways, which will not be listed one by one in this embodiment.

[0084] In addition, there are many ways for the extrusion drive member 231 to drive the transmission nut 2321 to rotate. In one possible implementation, see Figure 3 and Figure 5 A synchronous pulley structure 233 may be provided between the extrusion driving member 231 and the driving nut 2321 , and the extrusion driving member 231 may drive the driving nut 2321 to rotate via the synchronous pulley structure 233 .

[0085] Of course, the extrusion driving member 231 may also drive the driving nut 2321 to rotate in other ways, which is not limited in this embodiment.

[0086] It is worth noting that since the second extrusion member 22 is slidably arranged on the mounting frame 1 in a direction close to or away from the first extrusion member 21, and since the screw rod 2322 is threadedly connected to the transmission nut 2321 and extends along the moving direction of the second extrusion member 22, when the installation accuracy of the second extrusion member 22, the screw rod 2322, the transmission nut 2321 or the screw rod 2322 is not high enough, it is easy for the screw rod 2322 to get stuck or the second extrusion member 22 to get stuck. In order to avoid this situation, in some embodiments, see Figure 5 The second extrusion piece 22 is floatingly connected to the screw rod 2322 .

[0087] By making the second extrusion component 22 and the screw rod 2322 floatingly connected, even if the installation accuracy of the second extrusion component 22, the screw rod 2322, the transmission nut 2321 or the screw rod 2322 is not high enough to cause deviation from the preset position, the positional relationship between the second extrusion component 22 and the screw rod 2322 can be slightly changed to eliminate the position deviation caused by the low installation accuracy, thereby avoiding the screw rod 2322 or the second extrusion component 22 from getting stuck.

[0088] There are many ways to float the second extrusion member 22 and the screw rod 2322. In one possible implementation, see Figure 5 A plug-in structure 23222 is provided at the end of the screw rod 2322 , a limiting cavity 221 is provided on the second extrusion member 22 , and the plug-in structure 23222 is plugged into the limiting cavity 221 and has a gap with the cavity wall of the limiting cavity 221 .

[0089] Since the plug-in structure 23222 is plugged into the limiting cavity 221 and has a gap with the cavity wall of the limiting cavity 221, the gap between the plug-in structure 23222 and the cavity wall of the limiting cavity 221 can allow the position of the plug-in structure 23222 in the limiting cavity 221 to change slightly, and then the position of the screw rod 2322 relative to the second extrusion component 22 can change slightly, thereby achieving the purpose of floating connection between the second extrusion component 22 and the screw rod 2322.

[0090] Of course, the second extrusion member 22 and the screw rod 2322 may also be connected in a floating manner through other methods, which is not limited in this embodiment.

[0091] In order to make the plug-in structure 23222 smoother during the slight change in position in the limiting cavity 221, in some embodiments, see Figure 5At least part of the surface of the plug structure 23222 is a spherical surface 23222a. By making at least part of the surface of the plug structure 23222 a spherical surface 23222a, the spherical surface 23222a can reduce the friction between the plug structure 23222 and the cavity wall of the limiting cavity 221, thereby making the plug structure 23222 smoother when the position in the limiting cavity 221 changes slightly.

[0092] In some embodiments, see Figure 4 The plug-in structure 23222 is provided with a cutting portion, and the cavity wall of the limiting cavity 221 matches the cutting portion, and the cutting portion forms a rotation-stopping portion 23221. Since the cavity wall of the limiting cavity 221 matches the cutting portion, the cavity wall of the limiting cavity 221 and the cutting portion can jointly form a structure similar to the cooperation between a limiting pin and a limiting hole, thereby achieving a limiting effect, thereby achieving the purpose of preventing the screw rod 2322 from rotating around its own axial direction relative to the second extrusion member 22.

[0093] When the cutting portion forms the stop portion 23221, since the cutting portion can be manufactured by only cutting material on the plug-in structure 23222 without adding a new structure, the structure of the stop portion 23221 is simple, thereby achieving the effect of reducing the manufacturing cost of the stop portion 23221.

[0094] Of course, the anti-rotation portion 23221 may also be other possible structures, and this embodiment does not limit the anti-rotation portion 23221.

[0095] In some embodiments, see Figure 1 The mounting frame 1 includes: a first mounting member 11, a second mounting member 12 and a connecting member 13, wherein the second mounting member 12 and the first mounting member 11 are moved along the moving direction of the first extrusion member 21 or the second extrusion member 22 ( Figure 1 The first extrusion member 21 and the second extrusion member 22 are arranged relatively with each other in the Z-axis direction, and the connecting member 13 is arranged between the first mounting member 11 and the second mounting member 12 and is respectively connected to the first mounting member 11 and the second mounting member 12. The first extrusion member 21 and the second extrusion member 22 are both located between the first mounting member 11 and the second mounting member 12.

[0096] Since the first extrusion member 21 and the second extrusion member 22 are both located between the first mounting member 11 and the second mounting member 12, the first extrusion member 21 and the second extrusion member 22 will be wrapped in the space formed by the first mounting member 11 and the second mounting member 12. Such a configuration can make the environment in which the first extrusion member 21 and the second extrusion member 22 are located more closed and less susceptible to external influences, and can reduce or even avoid the possibility of interference with other external components during the movement of the first extrusion member 21 and the second extrusion member 22, thereby making the operation of the pre-pressing device 100 more reliable.

[0097] Among them, the above-mentioned first mounting member 11 and the second mounting member 12 can both be mounting plates, the above-mentioned connecting member 13 can be a connecting rod, the number of connecting rods can be four, five or six, etc. This embodiment does not limit the structure of the first mounting member 11, the second mounting member 12 and the connecting member 13, and the number of the connecting member 13.

[0098] In some embodiments, see Figure 3 and Figure 6 The pre-pressing device 100 also includes: a transport component 3, which is used to transport the piece A to be extruded between the first extrusion component 21 and the second extrusion component 22, and the transport component 3 is also used to move the piece A to be extruded away after the piece A to be extruded is released between the first extrusion component 21 and the second extrusion component 22.

[0099] By setting up the conveying component 3, the conveying component 3 can automatically convey the part A to be extruded to between the first extrusion component 21 and the second extrusion component 22, and move the part A to be extruded away after the part A to be extruded is released between the first extrusion component 21 and the second extrusion component 22, so that the pre-pressing device 100 has a higher degree of automation, thereby achieving the purpose of reducing the labor intensity of personnel.

[0100] There are many ways to implement the above-mentioned transport component 3. In a first possible implementation, the above-mentioned transport component 3 can transport a manipulator. In a second possible implementation, see Figure 6 The transport assembly 3 includes: a transmission drive member 31 and a conveyor belt 32, wherein the transmission drive member 31 is connected to the conveyor belt 32, and a part of the structure of the conveyor belt 32 is located between the first extrusion member 21 and the second extrusion member 22. The transmission drive member 31 is used to drive the conveyor belt 32 to transport the part A to be extruded between the first extrusion member 21 and the second extrusion member 22. The transmission drive member 31 is also used to continue to drive the conveyor belt 32 to transport the part A to be extruded after it is released between the first extrusion member 21 and the second extrusion member 22, so as to move the part A to be extruded away.

[0101] When the transport component 3 includes a transport drive member 31 and a conveyor belt 32, the purpose of transporting the workpiece A to be extruded to between the first extrusion member 21 and the second extrusion member 22 and moving the workpiece A away from between the first extrusion member 21 and the second extrusion member 22 can be achieved through the rotation of the conveyor belt 32. This method is low-cost and reliable in operation. Therefore, the cost of the pre-pressing device 100 can be reduced while ensuring the reliability of the operation of the pre-pressing device 100.

[0102] The transmission drive member 31 may be a structure composed of a driving roller and a motor, the motor is connected to the driving roller, and the conveyor belt 32 is sleeved on the driving roller. Of course, the transmission drive member 31 may also be other possible structures, which is not limited in this embodiment.

[0103] In order to improve the efficiency of the pre-pressing device 100 in flattening the extruded piece A, in some embodiments, see Figure 3 The number of pre-pressing assemblies 2 is multiple, and the multiple pre-pressing assemblies 2 are arranged in an array at intervals on the mounting frame 1. By making the number of pre-pressing assemblies 2 multiple, the multiple pre-pressing assemblies 2 can flatten the to-be-extruded piece A at the same time, thereby improving the efficiency of the pre-pressing device 100 in flattening the to-be-extruded piece A.

[0104] The number of the pre-pressing components 2 may be two, three or four, etc., which is not limited in this embodiment.

[0105] The present application also provides a winding machine 200, see Figure 7 , the winding machine 200 includes a pre-pressing device 100 .

[0106] Among them, the structure of the pre-pressing device 100 can be the same as the structure of the pre-pressing device 100 described in any of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the pre-pressing device 100 in the above embodiments, which will not be repeated in this embodiment.

[0107] In this embodiment, since the pre-pressing device 100 has a simple structure and a small volume, when the winding machine 200 includes the pre-pressing device 100, the winding machine 200 can have a simple structure and a small volume.
