Description

Technical Field

[0001] This utility model relates to battery winding machine equipment, and more particularly to a mechanism for accurately inserting electrode sheets into winding needles in a winding machine. Background Technology

[0002] A winding machine is an automated device for producing wound battery cells. It uses winding needles to clamp the battery's electrodes and separators together, and then rotates and winds them to form the battery cell. In the process of manufacturing wound battery cells, the winding needles first wind two separators several times, and then insert two electrodes between the two separators and between the separators and the winding needles. This process is called electrode insertion, and it fundamentally affects the alignment between the electrodes and the separators.

[0003] In the process of rolling battery cells, due to the possible errors in the thickness of the electrode itself, the electrode often deviates during the transmission process. This causes the electrode to not be accurately aligned with the preset insertion position during the insertion operation, resulting in poor quality of the rolled battery cells. Utility Model Content

[0004] The purpose of this invention is to provide an insertion mechanism that can accurately insert the head of the electrode into the desired position.

[0005] To achieve the above objectives, the electrode insertion mechanism of this utility model includes a mounting base, a flat plate assembly, a first driving mechanism, and a second driving mechanism. The flat plate assembly includes a fixed clamping plate and a movable clamping plate. The fixed clamping plate is fixed relative to the mounting base, and the movable clamping plate can move relative to the mounting base to approach and move away from the fixed clamping plate. The first driving mechanism drives the movable clamping plate to move on the mounting base. The second driving mechanism is connected to the mounting base and drives the mounting base to rotate about an axis; and the axis is the direction of movement of the movable clamping plate.

[0006] In some embodiments, a fixed plate and a movable plate are respectively installed on the fixed clamping plate and the movable clamping block. The fixed plate and the movable plate are arranged opposite to each other, and the distance between them is greater than the distance between the fixed clamping plate and the movable clamping plate.

[0007] In some embodiments, the first drive mechanism is a motor.

[0008] In some embodiments, the output shaft of the motor is connected to the movable clamp via a crank-connecting rod mechanism.

[0009] In some embodiments, a rotating mechanism is provided between the second drive mechanism and the mounting base to reduce the rotational motion output by the second drive mechanism.

[0010] In some embodiments, the rotating mechanism is a hollow rotating platform; the output end of the second driving mechanism is connected to the input end of the hollow rotating platform, and the mounting base is connected to the output end of the hollow rotating platform.

[0011] In some embodiments, a fixing seat is further included, which is disposed between the mounting base and the rotating mechanism, and the width of the fixing seat is greater than the width of the tread plate assembly.

[0012] In some embodiments, the input axis of the rotating mechanism is parallel to and staggered with the output axis.

[0013] In some embodiments, the first drive mechanism and the second drive mechanism are each a motor, and the output shafts of the two motors are perpendicular to each other.

[0014] In some embodiments, the output end of the first drive mechanism is connected to the middle of the movable clamp, and the motion output end of the second drive mechanism is connected to the middle of the mounting base.

[0015] In summary, the electrode insertion mechanism of this utility model achieves the movement of the moving clamping plate through the first driving mechanism, thereby making the electrode clamping operation faster and more precise. At the same time, the second driving mechanism can swing in the width direction of the electrode, thereby more precisely adjusting the insertion angle of the electrode head, which can effectively improve the alignment of the electrode insertion and the yield rate of the wound battery cells.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0021] exist Figures 1 to 3In the embodiment shown, the electrode insertion mechanism 100 of the present invention includes a mounting base 101 and a swivel assembly 110 disposed on the mounting base 101, a first drive mechanism 150 for driving the swivel assembly 110 to open and close, and a second drive mechanism 170 for driving the swivel assembly 110 to swing.

[0022] Please refer to the following: Figure 1 , 2 3. The smoothing plate assembly 110 includes a fixed clamping plate 111 and a movable clamping plate 112. The fixed clamping plate 111 is spaced apart from the mounting base 101 and fixed to it by a connecting plate 113. The movable clamping plate 112 is mounted on the mounting base 101 via a guide mechanism 114, allowing it to move along the guide mechanism 114 on the mounting base 101, thereby moving closer to and away from the fixed clamping plate 111. When the movable clamping plate 112 moves to be in close contact with the fixed clamping plate 111, the smoothing plate assembly 110 is in a clamped state, and the electrode passing between them can be clamped and fixed. When the movable clamping plate 112 separates from the fixed clamping plate 111, the smoothing plate assembly 110 is in an open state, and the electrode passing between them is released.

[0023] In this embodiment, the guide mechanism 114 includes two sets of flange-type linear bearings, which are respectively located near both ends of the movable clamping plate 112. Furthermore, to prevent the fixed clamping plate 111 and the movable clamping plate 112 from damaging the electrode sheet in the clamping state, elastic material pads can be optionally provided on their opposing clamping surfaces.

[0024] Since the electrode insertion mechanism 100 needs to insert the head of the electrode into the preset position of the winding needle, the head of the electrode must protrude from the fixed clamping plate 111 and the movable clamping plate 112. Therefore, a long rectangular fixed support plate 115 is installed on the bottom surface of the fixed clamping plate 111 along the insertion direction, and a corresponding movable support plate 116 is also provided on the bottom surface of the movable clamping plate 112. The distance between the fixed support plate 115 and the movable support plate 116 is slightly larger than the distance between the fixed clamping plate 111 and the movable clamping plate 112. This ensures that when the two clamping plates 111 and 112 clamp the electrode, the two support plates 115 and 116 are close to the head of the electrode but not clamped tightly, thereby ensuring that the head of the electrode is limited from shaking but not damaged.

[0025] Please refer to the following: Figure 2 , Figure 3The first drive mechanism 150 includes a first motor 151, a crank mechanism 152 with one end connected to the output shaft of the first motor 151, and a connecting rod mechanism 153 hinged to the other end of the crank mechanism 152. The first motor 151 is mounted on a motor base 154, which is located on a mounting base 101 and is respectively located on both sides of the mounting base 101 with the plate assembly 110. One end of the connecting rod mechanism 153 passes through an opening in the mounting base 101 and connects to the movable clamping plate 112 of the plate assembly 110. In this way, when the first motor 151 is working, the movable clamping plate 112 can be driven to move quickly through the crank-connecting rod mechanism, with fast response speed, high precision, and fine adjustment of the output clamping force to avoid damage to the electrode sheets.

[0026] Please see Figure 2 , Figure 3 The second drive mechanism 170 includes a second motor 171 and a rotating mechanism 172. The rotating mechanism 172 has an input end 1721 and an output end 172. The output shaft of the second motor 171 is connected to the input end 1721 of the rotating mechanism 172, and the output end 1722 is used to output the rotational motion of the second motor 171. The output end of the rotating mechanism 172 is connected to the mounting base 101, so that the rotational motion of the second motor 171 can adjust the position of the guide plate assembly 110 in the direction perpendicular to the electrode plate, and then adjust the angle of the electrode plate head in the width direction of the electrode plate, ultimately achieving the effect of precisely aligning the insertion plate position.

[0027] In this embodiment, the rotating mechanism 172 is implemented using a hollow rotating platform. This hollow rotating platform can convert the rapid movement of the second motor 171 into a slower, more accurate, and more stable rotational movement, thereby achieving the purpose of precisely adjusting the position of the electrode head. In addition, since the axis of the input end 1721 of the hollow rotating platform is parallel to and offset from the axis of the output end 1722, the rotation of the second motor 172 can be transmitted from the middle of the mounting base 101 to the tread plate assembly 110. At the same time, the first motor 171 can also drive the moving clamp 112 from the middle of the mounting base 101 to clamp and release the electrode. Therefore, the overall mechanism layout is more reasonable and the output movement is more stable.

[0028] like Figure 1 and Figure 3 As shown, the insert mechanism 100 in this embodiment also includes a fixing base 180 for mounting the insert mechanism 100 onto the main board of the winding machine. The fixing base 180 has a through hole 181, through which the rotating surface of the hollow rotating platform in the embodiment of the rotating mechanism 172 passes and is fixed to the mounting base 101. The width of the fixing base 180 is greater than the width of the flat plate assembly 110, thereby reserving an appropriate distance between the flat plate assembly 110 and the main board of the winding machine to facilitate the flat plate assembly 110 to swing in the electrode width direction to adjust the insert angle of the electrode head.

[0029] like Figure 2 and Figure 4 As shown, in this embodiment, the output shaft of the first motor 151 is perpendicular to the moving direction of the moving clamp 112, the output shaft of the second motor 152 is parallel to the moving direction of the moving clamp 112, and the two motors are arranged side by side on one side of the mounting base 101.

[0030] In this embodiment, the first motor 151 drives the moving clamping plate 112 toward the fixed clamping plate 111 via a crank-connecting rod mechanism to achieve the electrode clamping operation, which has a fast response speed and high precision. At the same time, the second motor 171 can swing in the electrode width direction, thereby more accurately adjusting the insertion angle of the electrode head, which can effectively improve the alignment of the electrode insertion and the yield rate of the wound battery cells.

[0031] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model is defined by the claims.
