Description

Insertion device and cell winding equipment

[0001] This disclosure claims priority to Chinese Patent Application No. 202423066428.4, filed on December 11, 2024, entitled "Insertion Device and Cell Winding Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of battery processing equipment technology, and in particular to an insert device and a cell winding device. Background Technology

[0003] A battery cell winding machine is a device used to manufacture battery cells. A battery cell winding machine typically includes an insertion device and a winding needle. The winding needle is located downstream of the insertion device. The insertion device feeds the electrode sheets to the winding needle and inserts the head end of the electrode sheet into the winding needle, so that when the winding needle rotates, it winds the electrode sheet and other components around itself to create a battery cell.

[0004] However, before the head end is inserted into the needle, the transmission trajectory is uncontrollable and prone to tilting because the head end is suspended between the insert device and the needle. Therefore, this will result in low positional accuracy after the head end is inserted into the needle. Summary of the Invention

[0005] This disclosure provides an insert device and a cell winding equipment, which enables high positional accuracy after the head end of the strip is inserted into the winding needle.

[0006] To achieve the above objectives, in a first aspect, this disclosure discloses an insert device, comprising:

[0007] A feeding mechanism, wherein the feeding mechanism is used to convey a material belt along a preset trajectory; and,

[0008] The material support mechanism includes a material support drive and a material support assembly. The material support assembly is located downstream of the feeding mechanism. The material support drive is disposed on the feeding mechanism and is used to drive the material support assembly to move along the preset trajectory toward or away from the feeding mechanism.

[0009] When the inserting device is used in a battery cell winding machine, and the head end of the strip needs to be inserted into the winding needle via the inserting device, firstly, the inserting device can be positioned upstream of the winding needle, with the winding needle positioned on a preset track. Then, the feeding mechanism can convey the strip along the preset track towards the winding needle. Since the material support assembly is located downstream of the feeding mechanism, when the strip is at the material support assembly, the material support assembly can confine the strip within the preset track, ensuring that the strip does not deviate from the preset track relative to the material support assembly, thus guaranteeing the accuracy of the strip's position.

[0010] When the strip between the material support assembly and the winding needle is cut, and the head end of the strip after being cut exceeds the material support assembly and is located between the material support assembly and the winding needle, the head end of the strip is suspended in the air due to the lack of support and limiting effect of the material support assembly. At this time, it is easy for the head end of the strip to lift up and deviate from the preset trajectory.

[0011] To avoid this situation, the material support assembly can be driven by the material support drive to move along a preset trajectory away from the feeding mechanism. In other words, the material support assembly can be driven by the material support drive to move along a preset trajectory towards the head end, so that the head end of the material strip can still be supported by the material support assembly. In this way, the head end of the material strip can be prevented from tilting up and deviating from the preset trajectory, thereby making the positional accuracy of the head end after inserting into the winding needle higher.

[0012] Optionally, the material support assembly forms a limiting gap, which is located on the preset track for the material belt to pass through.

[0013] Because the limiting seam can partially wrap around the material strip and limit it from multiple directions, it has a better limiting effect on the material strip.

[0014] Optionally, the material support assembly includes:

[0015] The first pallet; and,

[0016] The second pallet is spaced apart from the first pallet along a first direction to form the limiting gap. Along the first direction, at least one of the first pallet and the second pallet can move closer to or further away from the other to adjust the width of the limiting gap. The first pallet and the second pallet are used to prevent the material belt from moving along the first direction.

[0017] Since at least one of the first and second support plates can move closer to or further away from the other along the first direction, the width of the limiting slot can be flexibly adjusted, thereby enabling the limiting slot to match material strips of different thicknesses well, thus making the material support assembly more compatible.

[0018] In addition, since the first and second pallets can prevent the material belt from moving in the first direction, the material belt can be confined to the preset track, thereby ensuring the accuracy of the material belt in position.

[0019] Optionally, the first pallet includes a first guide section near the feeding mechanism, and the second pallet includes a second guide section near the feeding mechanism. Along the direction from the material support assembly to the feeding mechanism, the distance between the first guide section and the second guide section gradually increases.

[0020] As the distance between the first guide section and the second guide section gradually increases along the direction from the material support assembly to the feeding mechanism, the end of the limiting slot near the feeding mechanism can be wider. In this way, when the feeding mechanism conveys the head end of the material belt along the preset trajectory away from the feeding mechanism to the limiting slot, it can easily enter the limiting slot, thereby reducing the possibility that the head end of the material belt cannot enter the limiting slot.

[0021] Optionally, the first tray includes a first insertion section away from the feeding mechanism, and the second tray includes a second insertion section away from the feeding mechanism. The side of the first insertion section away from the second insertion section and / or the side of the second insertion section away from the first insertion section are provided with a thinning portion.

[0022] By providing a thinning portion on the side of the first insertion segment away from the second insertion segment and / or on the side of the second insertion segment away from the first insertion segment, the sum of the thicknesses of the first insertion segment and the second insertion segment along the first direction can be reduced, thereby allowing the first insertion segment and the second insertion segment to be easily inserted into the seam of the needle, thus achieving a better effect of inserting the head end of the strip into the needle.

[0023] Optionally, the material support assembly further includes:

[0024] A material support bracket, connected to the material support drive member, and slidably disposed on the feeding mechanism along a preset trajectory in a direction approaching or moving away from the feeding mechanism; the material support drive member is used to drive the material support bracket to move along the preset trajectory in a direction approaching or moving away from the feeding mechanism; a second pallet is fixed to the material support bracket, and the first pallet is slidably disposed on the material support bracket along the first direction; and...

[0025] A gap adjustment drive is provided on the material support bracket and connected to the first support plate, and is used to drive the first support plate to move closer to or further away from the second support plate along the first direction.

[0026] Since the material support bracket is connected to the material support drive and is slidably disposed on the feeding mechanism along a preset trajectory toward or away from the feeding mechanism, when the material support drive drives the material support bracket to move along the preset trajectory toward or away from the feeding mechanism, the material support bracket can move more smoothly and stably.

[0027] Optionally, the material support bracket includes:

[0028] The first material support mounting component is slidably disposed on the feeding mechanism along the preset trajectory in a direction that is closer to or farther away from the feeding mechanism;

[0029] The second material support mounting component is spaced apart from the first material support mounting component along the first direction;

[0030] A material support connector is provided, which is connected between the first material support mounting component and the second material support mounting component. The material support driving component is connected to the material support connector and is used to drive the material support connector to move along the preset trajectory toward or away from the feeding mechanism.

[0031] The second pallet is fixed to the second material support mounting member and located between the first material support mounting member and the second material support mounting member. The first pallet is slidably disposed on the side of the first material support mounting member close to the second material support mounting member along the first direction. The gap adjustment drive member is disposed on the first material support mounting member and connected to the first pallet.

[0032] Since the second pallet is fixed to the second material support mounting member and located between the first material support mounting member and the second material support mounting member, and the first pallet is slidably disposed on the side of the first material support mounting member closer to the second material support mounting member along the first direction, the second pallet and the first pallet will be located between the first material support mounting member and the second material support mounting member along the first direction.

[0033] In this way, on the one hand, the first and second material support mounting components can protect the second and first pallets from both sides, making the environment in which the second and first pallets are located more stable, thus preventing the movement of the first pallet from being disturbed by the external environment. On the other hand, the first and second material support mounting components can also limit the movement of the first pallet, ensuring that the first pallet can only move between the first and second material support mounting components, thereby avoiding the situation where the first pallet moves too far away from the second pallet in the first direction, resulting in an excessively wide limiting gap.

[0034] Optionally, the material support assembly further includes:

[0035] A limiting member, at least a portion of which is located on the side of the first pallet facing the second pallet and on the movement trajectory of the first pallet, is adjustablely disposed on the material support bracket along the first direction.

[0036] By positioning at least a portion of the limiting member on the side of the first pallet facing the second pallet and on the movement trajectory of the first pallet, when the first pallet moves toward the limiting member in the first direction, the limiting member will prevent the first pallet from continuing to move toward the second pallet in the first direction. This avoids the situation where the limiting gap width is too narrow due to excessive movement of the first pallet in the first direction toward the second pallet.

[0037] In addition, by making the limiting member adjustable along the first direction on the material support bracket, the limiting degree of the limiting member on the first support plate can be adjusted. In this way, the position of the limiting member can be freely adjusted according to the thickness change of the material strip along the first direction, so that the material support assembly can play a good limiting role for material strips of different thicknesses, while also avoiding the situation where the material strip is clamped and cannot move due to the narrow limiting gap width.

[0038] Optionally, the limiting member is an adjusting screw, which is threadedly connected to the material support bracket and located on the side of the first support plate facing the second support plate, and the adjusting screw extends along the first direction.

[0039] Since the adjusting screw is threaded onto the material support bracket, its position can be adjusted along the first direction simply by rotating it, making the process very simple.

[0040] Optionally, the feeding mechanism includes:

[0041] A feeding bracket, wherein the material support drive component is disposed on the feeding bracket;

[0042] A first clamping roller is rotatably mounted on the feeding bracket;

[0043] The second clamping roller is rotatably disposed on the feeding bracket, and the second clamping roller and the first clamping roller are spaced apart and opposite to each other along a first direction to form a clamping gap.

[0044] Since both the first and second clamping rollers are rotatably mounted on the feeding bracket, and the second clamping roller and the first clamping roller are spaced apart and form a clamping gap along the first direction, when the material strip passes through the clamping gap, on the one hand, the clamping action of the first and second clamping rollers can shape the material strip, making it flatter; on the other hand, the friction between the material strip and the first and second clamping rollers can be rolling friction, which reduces the friction force and can, to a certain extent, prevent the material strip from being scratched by the first or second clamping roller.

[0045] Optionally, the feeding bracket includes:

[0046] The fixed base, wherein the material support drive component is disposed on the fixed base;

[0047] A first clamping roller mounting component is slidably disposed on the fixed base along the first direction, and the first clamping roller is rotatably disposed on the first clamping roller mounting component;

[0048] The second clamping roller mounting component is fixedly mounted on the fixed base, and the second clamping roller is rotatably mounted on the second clamping roller mounting component.

[0049] By setting up a first clamping roller mounting component and a second clamping roller mounting component, both the first clamping roller and the second clamping roller can have dedicated positions for installation, thereby making the installation of the first clamping roller and the second clamping roller more convenient.

[0050] In addition, by making the first clamping roller mounting part slidably disposed on the fixed seat along the first direction, the width of the clamping gap along the first direction can be adjusted. On the one hand, this allows the feeding mechanism to adapt to material strips of different thicknesses, thus improving compatibility. On the other hand, when it is necessary to insert the material strip into the clamping gap, the width of the clamping gap can be increased, thereby simplifying the work of inserting the material strip into the clamping gap.

[0051] Optionally, the feeding mechanism further includes:

[0052] A clamping drive assembly is disposed on the fixed base and is used to drive the first clamping roller mounting member to move toward or away from the second clamping roller mounting member along the first direction.

[0053] By setting up a clamping drive assembly, the clamping drive assembly can automatically drive the first clamping roller mounting part to move closer to or further away from the second clamping roller mounting part along the first direction, thereby automatically achieving the purpose of adjusting the width of the clamping gap along the first direction, resulting in a higher degree of automation.

[0054] Optionally, the clamping drive assembly includes:

[0055] A clamping drive is provided on the fixed base, and a cam is provided on the rotating shaft of the clamping drive. The peripheral wall of the cam abuts against the first clamping roller mounting member along the first direction.

[0056] An elastic element is provided to the first clamping roller mount to drive the first clamping roller mount to move away from the second clamping roller mount along the first direction.

[0057] By cooperating with the cam and the elastic element, the rotational motion of the clamping drive shaft can be converted into the linear motion of the first clamping roller mounting part along the first direction. In this way, when selecting the clamping drive, there is no need to choose expensive linear motors, etc., and thus the cost of the clamping drive can be reduced to a certain extent.

[0058] Optionally, the fixing base is provided with a guide hole that penetrates the fixing base along the first direction;

[0059] The first clamping roller mounting component is provided with a guide rod, which is slidably inserted through the guide hole along the first direction. The guide rod includes an exposed end that is away from the first clamping roller mounting component and protrudes from the fixed seat. The elastic element is clamped between the fixed seat and the exposed end.

[0060] Since the guide rod is slidably inserted through the guide hole in the first direction, and the first clamping roller mounting component is disposed on the guide rod, the first clamping roller mounting component can move more smoothly in the first direction under the cooperation of the guide rod and the guide hole.

[0061] Furthermore, by clamping an elastic element between the fixed seat and the exposed end, the elastic element will be compressed when the clamping drive member presses the first clamping roller mounting member by the cam to drive the first clamping roller mounting member to move closer to the second clamping roller mounting member in the first direction. When the cam stops pressing the first clamping roller mounting member, the elastic element will return to its original shape. During the process of the elastic element returning to its original shape, it will push the first clamping roller mounting member to move away from the second clamping roller mounting member in the first direction through the exposed end.

[0062] Secondly, this disclosure discloses a battery cell winding device, comprising:

[0063] The insert device described in any of the first aspects above; and,

[0064] A winding needle is located on the preset track and downstream of the material support assembly.

[0065] Because the inserting device can drive the material support assembly to move closer to the head end via the material support drive, the head end of the strip can be supported by the material support assembly. This prevents the head end of the strip from tilting up or deviating from the preset trajectory, resulting in higher positional accuracy after the head end is inserted into the winding needle. Based on this, when the winding needle rotates to wind the strip around itself to produce the battery cell, the quality of the battery cell is better.

[0066] Optionally, the insert device further includes:

[0067] A insert drive is provided, and the feeding mechanism is disposed on the insert drive. The insert drive is used to drive the feeding mechanism to move along the preset trajectory toward the direction of the winding needle.

[0068] Since the insert drive can drive the feeding mechanism to move along a preset trajectory toward the direction of the winding needle, the material support component can be directly inserted into the winding needle under the action of the insert drive, thereby achieving the purpose of inserting the head end into the winding needle more accurately.

[0069] Compared with related technologies, the beneficial effects of this disclosure are as follows:

[0070] In this disclosure, when the inserting device is applied to a cell winding equipment, and the head end of the strip needs to be inserted into the winding needle via the inserting device, firstly, the inserting device can be positioned upstream of the winding needle, and the winding needle can be positioned on a preset track. Then, the strip can be conveyed along the preset track towards the winding needle by a feeding mechanism. Since the material support assembly is located downstream of the feeding mechanism, when the strip is at the material support assembly, the material support assembly can limit the strip to the preset track, ensuring that the strip does not deviate from the preset track relative to the material support assembly, thereby guaranteeing the accuracy of the strip's position.

[0071] When the strip between the material support assembly and the winding needle is cut, and the head end of the strip after being cut exceeds the material support assembly and is located between the material support assembly and the winding needle, the head end of the strip is suspended in the air due to the lack of support and limiting effect of the material support assembly. At this time, it is easy for the head end of the strip to lift up and deviate from the preset trajectory.

[0072] To avoid this situation, the material support assembly can be driven by the material support drive to move along a preset trajectory away from the feeding mechanism. In other words, the material support assembly can be driven by the material support drive to move along a preset trajectory towards the head end, so that the head end of the material strip can still be supported by the material support assembly. In this way, the head end of the material strip can be prevented from tilting up and deviating from the preset trajectory, thereby making the positional accuracy of the head end after inserting into the winding needle higher.

[0088] Before explaining the technical solution of this disclosure, the background technology of this disclosure shall be explained first.

[0089] A battery cell winding machine is a device used to manufacture battery cells. A battery cell winding machine typically includes an insertion device and a winding needle. The winding needle is located downstream of the insertion device. The insertion device feeds the electrode sheets to the winding needle and inserts the head end of the electrode sheet into the winding needle, so that when the winding needle rotates, it winds the electrode sheet and other components around itself to create a battery cell.

[0090] However, before the head end is inserted into the winding needle, it is suspended between the insert device and the winding needle, making the transmission trajectory uncontrollable and prone to tilting. This results in low positional accuracy after the head end is inserted into the winding needle. Therefore, this disclosure provides an insert device 100 and a cell winding apparatus 200 to solve the above problems.

[0091] The technical solutions of this disclosure will now be described in conjunction with specific embodiments and accompanying drawings.

[0092] Figure 1 is a structural schematic diagram of the insert device 100 provided in an embodiment of the present disclosure, Figure 2 is a structural schematic diagram of the insert device 100 in Figure 1 viewed from the negative Z-axis direction, and Figure 3 is a simplified structural schematic diagram of the insert device 100 in Figure 1 applied to the cell winding equipment 200.

[0093] Referring to Figures 1, 2 and 3, the insert device 100 includes a feeding mechanism 1 and a material support mechanism 2. The feeding mechanism 1 is used to convey the material belt L along a preset trajectory G. The material support mechanism 2 includes a material support drive 21 and a material support assembly 22. The material support assembly 22 is located downstream of the feeding mechanism 1 and is used to limit the material belt L to the preset trajectory G. The material support drive 21 is disposed on the feeding mechanism 1 and is used to drive the material support assembly 22 to move along the preset trajectory G in a direction closer to or farther from the feeding mechanism 1 (the negative or positive direction of the X-axis in Figure 3).

[0094] In this embodiment, when the inserting device 100 is applied to the cell winding equipment 200, when it is necessary to insert the head end L1 of the strip L into the winding needle 300 through the inserting device 100, firstly, the inserting device 100 can be positioned upstream of the winding needle 300, and the winding needle 300 can be positioned on a preset trajectory G. Then, the strip L can be conveyed along the preset trajectory G towards the winding needle 300 by the feeding mechanism 1. Since the material support assembly 22 is located downstream of the feeding mechanism 1, when the strip L is located at the material support assembly 22, the material support assembly 22 can limit the strip L to the preset trajectory G, so that the strip L will not deviate from the preset trajectory G relative to the material support assembly 22, thereby ensuring the positional accuracy of the strip L.

[0095] When the material strip L located between the material support assembly 22 and the winding needle 300 is cut, and the head end L1 formed after the material strip L is cut exceeds the material support assembly 22 and is located between the material support assembly 22 and the winding needle 300, the head end L1 of the material strip L is in a suspended state due to the lack of support and limiting effect of the material support assembly 22. At this time, it is easy for the head end L1 of the material strip L to lift up and deviate from the preset trajectory G.

[0096] To avoid this situation, the material support assembly 22 can be driven by the material support drive 21 to move along the preset trajectory G in a direction away from the feeding mechanism 1 (the positive direction of the X-axis in Figure 3). In other words, the material support drive 21 can drive the material support assembly 22 to move along the preset trajectory G in a direction closer to the head end L1 (the positive direction of the X-axis in Figure 3), so that the head end L1 of the material strip L can still be supported by the material support assembly 22. In this way, the head end L1 of the material strip L can be prevented from tilting up and deviating from the preset trajectory G, thereby making the positional accuracy of the head end L1 after it is inserted into the winding needle 300 higher.

[0097] The aforementioned material strip L can be an electrode sheet or any other possible strip-shaped component, and this embodiment does not limit this. The aforementioned material support drive 21 can be a cylinder, an electric cylinder, or any other structure capable of driving the material support assembly 22 to move along a preset trajectory G toward or away from the feeding mechanism 1, and this embodiment does not limit the material support drive 21.

[0098] It should be noted that there are multiple ways to implement the material support component 22 to limit the material belt L to the preset trajectory G. In one possible implementation, as shown in Figures 1 and 3, the material support component 22 forms a limiting slot 10, and the limiting slot 10 is located on the preset trajectory G through which the material belt L passes.

[0099] Since the limiting seam 10 can partially wrap the material strip L and limit it from multiple directions, the limiting effect of the material strip L is better, thus better ensuring the positional accuracy of the material strip L.

[0100] In some embodiments, referring to Figures 1 and 4, Figure 4 is a structural schematic diagram of the insert device 100 in Figure 1 from a positive Y-axis view. The material support assembly 22 includes a first support plate 221 and a second support plate 222, wherein the second support plate 222 and the first support plate 221 are spaced apart from each other along a first direction (Z-axis direction in Figure 1) to form a limiting slot 10. Along the first direction, at least one of the first support plate 221 and the second support plate 222 can move closer to or further away from the other to adjust the width of the limiting slot 10. The first direction is perpendicular to the preset trajectory G, and the first support plate 221 and the second support plate 222 are used to prevent the material belt L from moving along the first direction.

[0101] Since at least one of the first support plate 221 and the second support plate 222 can move closer to or further away from the other along the first direction (Z-axis direction in Figure 1), the width of the limiting slot 10 can be flexibly adjusted, so that the limiting slot 10 can be well matched with material strips L of different thicknesses, thereby making the material support assembly 22 more compatible.

[0102] In addition, since the first pallet 221 and the second pallet 222 can prevent the material strip L from moving along the first direction, the material strip L can be limited to the preset trajectory G, thereby ensuring the accuracy of the material strip L in position.

[0103] In order to enable the feeding mechanism 1 to properly convey the head end L1 of the material belt L to the limiting slot 10, so that the limiting slot 10 can subsequently limit the material belt L to the preset trajectory G, in some embodiments, referring to Figures 1 and 4, the first pallet 221 includes a first guide section 2211 near the feeding mechanism 1, and the second pallet 222 includes a second guide section 2221 near the feeding mechanism 1. Along the direction from the material support assembly 22 to the feeding mechanism 1 (the negative direction of the X-axis in Figure 4), the distance between the first guide section 2211 and the second guide section 2221 gradually increases.

[0104] As the distance between the first guide segment 2211 and the second guide segment 2221 gradually increases along the direction from the material support assembly 22 to the feeding mechanism 1 (the negative direction of the X-axis in Figure 4), the end of the limiting slot 10 near the feeding mechanism 1 can be wider. In this way, when the feeding mechanism 1 conveys the head end L1 of the material belt L along the preset trajectory G in a direction away from the feeding mechanism 1 to the limiting slot 10, it can easily enter the limiting slot 10, thereby reducing the possibility that the head end L1 of the material belt L cannot enter the limiting slot 10.

[0105] In some embodiments, referring to Figures 1 and 3, the first pallet 221 includes a first insertion section 2212 away from the feeding mechanism 1, and the second pallet 222 includes a second insertion section 2222 away from the feeding mechanism 1. A thinning portion 20 is provided on the side of the first insertion section 2212 away from the second insertion section 2222 and / or on the side of the second insertion section 2222 away from the first insertion section 2212.

[0106] By providing a thinning portion 20 on the side of the first insertion segment 2212 away from the second insertion segment 2222 and / or the side of the second insertion segment 2222 away from the first insertion segment 2212, the sum of the thicknesses of the first insertion segment 2212 and the second insertion segment 2222 along the first direction (Z-axis direction in FIG3) can be thinned, thereby making it easy for the first insertion segment 2212 and the second insertion segment 2222 to be inserted together into the needle seam of the needle 300, thus achieving the effect of better inserting the head end L1 of the material strip L into the needle 300.

[0107] In some embodiments, referring to Figures 1 and 5, Figure 5 is a structural schematic diagram of the material support assembly 22 in Figure 1. The material support assembly 22 further includes a material support bracket 223 and a gap adjustment drive member 224. The material support bracket 223 is connected to the material support drive member 21 and is slidably disposed on the feeding mechanism 1 along a preset trajectory G in a direction closer to or farther from the feeding mechanism 1 (X-axis direction in Figure 5). The material support drive member 21 is used to drive the material support bracket 223 to move along the preset trajectory G in a direction closer to or farther from the feeding mechanism 1. A second support plate 222 is fixed to the material support bracket 223, and a first support plate 221 is slidably disposed on the material support bracket 223 along a first direction (Z-axis direction in Figure 5). The gap adjustment drive member 224 is disposed on the material support bracket 223 and connected to the first support plate 221, and is used to drive the first support plate 221 to move along the first direction closer to or farther from the second support plate 222.

[0108] Since the material support bracket 223 is connected to the material support drive member 21 and is slidably disposed on the feeding mechanism 1 along the preset trajectory G in the direction of approaching or moving away from the feeding mechanism 1 (X-axis direction in Figure 5), when the material support drive member 21 drives the material support bracket 223 to move along the preset trajectory G in the direction of approaching or moving away from the feeding mechanism 1, the material support bracket 223 can move more smoothly and stably.

[0109] It should be noted that there are multiple ways to implement the above-mentioned material support bracket 223 being slidably disposed on the feeding mechanism 1 along the preset trajectory G in a direction closer to or farther from the feeding mechanism 1. In one possible implementation, referring to Figures 1 and 5, a slide rail assembly 225 can be provided between the material support bracket 223 and the feeding mechanism 1. Specifically, the guide rail of the slide rail assembly 225 extends along the preset trajectory G and is disposed on the feeding mechanism 1, and the slider of the slide rail assembly 225 is slidably disposed on the guide rail along the extension direction of the guide rail. The material support bracket 223 is disposed on the slider. In this way, the purpose of slidably disposing the material support bracket 223 on the feeding mechanism 1 along the preset trajectory G in a direction closer to or farther from the feeding mechanism 1 can be achieved.

[0110] Of course, the purpose of slidably setting the material support bracket 223 on the feeding mechanism 1 can also be achieved in other ways, and this embodiment does not limit this.

[0111] In order to make the material support bracket 223 slide more smoothly and stably along the preset trajectory G towards or away from the feeding mechanism 1, in some embodiments, referring to Figures 1 and 5, the number of slide rail assemblies 225 can be two. When the number of slide rail assemblies 225 is two, the material support bracket 223 can slide more smoothly and stably, and is less prone to shaking.

[0112] Of course, the slide rail assembly 225 can also be other possible numbers. For example, the number of slide rail assemblies 225 can be one, three or four, etc. This embodiment does not limit this.

[0113] Since the second support plate 222 is fixed to the material support bracket 223, and the first support plate 221 is slidably disposed on the material support bracket 223 along the first direction (Z-axis direction in Figure 5), and the gap adjustment drive 224 is disposed on the material support bracket 223 and connected to the first support plate 221, when the gap adjustment drive 224 drives the first support plate 221 to move closer to or further away from the second support plate 222 along the first direction, the purpose of adjusting the width of the limiting gap 10 can be achieved.

[0114] By fixing the second pallet 222 to the material support bracket 223 and slidably setting the first pallet 221 on the material support bracket 223 along the first direction, only one of the second pallet 222 and the first pallet 221 can be movable while the other pallet remains stationary. In this way, the number of movable pallets can be reduced as much as possible while ensuring that the width of the limiting gap 10 can be adjusted. This simplifies the structure of the material support assembly 22 to a certain extent and reduces the cost of the material support assembly 22.

[0115] It should be noted that the gap adjustment drive 224 mentioned above can be a cylinder, an electric cylinder or other possible components, and this embodiment does not limit it.

[0116] In some embodiments, referring to Figures 1 and 5, the material support bracket 223 includes: a first material support mounting member 2231, a second material support mounting member 2232, and a material support connector 2233. The first material support mounting member 2231 is slidably disposed on the feeding mechanism 1 along a preset trajectory G in a direction closer to or farther from the feeding mechanism 1. The second material support mounting member 2232 is spaced apart from the first material support mounting member 2231 along a first direction (Z-axis direction in Figure 1). The material support connector 2233 is connected between the first material support mounting member 2231 and the second material support mounting member 2232. The material support driving member 21 is connected to the material support connector 2233 and is used to drive the material support connector 2233 to move along the preset trajectory G in a direction closer to or farther from the feeding mechanism 1.

[0117] The second pallet 222 is fixed to the second material support mounting member 2232 and located between the first material support mounting member 2231 and the second material support mounting member 2232. The first pallet 221 is slidably disposed on the side of the first material support mounting member 2231 near the second material support mounting member 2232 along the first direction (Z-axis direction in Figure 1). The gap adjustment drive member 224 is disposed on the first material support mounting member 2231 and connected to the first pallet 221.

[0118] Since the second pallet 222 is fixed to the second material support mounting member 2232 and located between the first material support mounting member 2231 and the second material support mounting member 2232, and the first pallet 221 is slidably disposed on the side of the first material support mounting member 2231 near the second material support mounting member 2232 along the first direction, the second pallet 222 and the first pallet 221 will be located between the first material support mounting member 2231 and the second material support mounting member 2232 along the first direction (Z-axis direction in FIG1).

[0119] In this way, on the one hand, the first material support mounting component 2231 and the second material support mounting component 2232 can protect the second pallet 222 and the first pallet 221 from both sides, making the environment of the second pallet 222 and the first pallet 221 more stable, and thus making the movement of the first pallet 221 free from interference from the external environment. On the other hand, the first material support mounting component 2231 and the second material support mounting component 2232 can also limit the movement of the first pallet 221, so that the first pallet 221 can only move between the first material support mounting component 2231 and the second material support mounting component 2232, thereby avoiding the situation where the first pallet 221 moves too far away from the second pallet 222 in the first direction, resulting in the width of the limiting gap 10 being too large.

[0120] The first material support mounting component 2231, the second material support mounting component 2232, and the material support connector 2233 can all be plate-shaped structures or other possible shapes, and this embodiment does not limit them.

[0121] It should be noted that there are multiple ways to realize the first pallet 221 being slidably disposed on the first material mounting member 2231 along the first direction. For example, it can be realized by the mutual cooperation between the guide rod and the guide hole. Of course, it can also be realized by other possible methods. This embodiment does not limit this.

[0122] To prevent the limiting gap 10 from becoming too narrow due to excessive travel when the gap adjustment drive 224 drives the first pallet 221 to move closer to the second pallet 222 in the first direction, which would cause the material strip L in the limiting gap 10 to be clamped by the first pallet 221 and the second pallet 222 and thus prevent the material strip L from being conveyed, in some embodiments, referring to Figures 4 and 5, the material support assembly 22 further includes a limiting member 226. At least a portion of the limiting member 226 is located on the side of the first pallet 221 facing the second pallet 222 (the lower side of the first pallet 221 in Figure 5) and is located on the movement trajectory of the first pallet 221. The limiting member 226 is adjustablely disposed on the material support bracket 223 in the first direction.

[0123] By positioning at least a portion of the limiting member 226 on the side of the first pallet 221 facing the second pallet 222 and on the movement trajectory of the first pallet 221, when the first pallet 221 moves towards the second pallet 222 in the first direction and reaches the limiting member 226, the limiting member 226 will prevent the first pallet 221 from continuing to move towards the second pallet 222 in the first direction. This avoids the situation where the limiting gap 10 is too narrow due to excessive movement of the first pallet 221 towards the second pallet 222 in the first direction.

[0124] In addition, by making the limiting member 226 adjustable along the first direction (Z-axis direction in Figure 5) on the material support bracket 223, the limiting degree of the limiting member 226 on the first support plate 221 can be adjusted. In this way, the position of the limiting member 226 can be freely adjusted according to the thickness change of the material strip L along the first direction, so that the material support assembly 22 can play a good limiting role for material strips L of different thicknesses, while also avoiding the situation where the material strip L is clamped and cannot move due to the narrow width of the limiting gap 10.

[0125] There are multiple ways to implement the aforementioned limiting member 226. In one possible implementation, as shown in Figures 4 and 5, the limiting member 226 is an adjusting screw. The adjusting screw is threadedly connected to the material support bracket 223 and is located on the side of the first support plate 221 facing the second support plate 222. The adjusting screw extends along the first direction.

[0126] Since the adjusting screw is threaded onto the material support bracket 223, the position of the adjusting screw can be adjusted along the first direction by rotating the adjusting screw, which is very simple.

[0127] In addition, since the adjusting screw has a simple structure, the cost of the limiting component 226 can be reduced to some extent.

[0128] Of course, the limiting member 226 can also be other possible structures, and this embodiment does not limit it.

[0129] In some embodiments, referring to Figures 1, 2 and 4, the feeding mechanism 1 includes: a feeding bracket 11, a first clamping roller 12 and a second clamping roller 13, wherein a material support drive member 21 is disposed on the feeding bracket 11, the first clamping roller 12 and the second clamping roller 13 are rotatably disposed on the feeding bracket 11, and the second clamping roller 13 and the first clamping roller 12 are spaced apart from each other in a first direction to form a clamping gap 30, the clamping gap 30 is used for the feeding belt L to pass through, so as to convey the feeding belt L along a preset trajectory G.

[0130] Since both the first clamping roller 12 and the second clamping roller 13 are rotatably mounted on the feeding bracket 11, and the second clamping roller 13 and the first clamping roller 12 are spaced apart and form a clamping gap 30 along the first direction, when the material strip L passes through the clamping gap 30, on the one hand, the clamping action of the first clamping roller 12 and the second clamping roller 13 can play a shaping role on the material strip L, making the material strip L flatter. On the other hand, the friction between the material strip L and the first clamping roller 12 and the second clamping roller 13 can be rolling friction, with less friction force, which can avoid the material strip L being scratched by the first clamping roller 12 or the second clamping roller 13 to a certain extent.

[0131] In some embodiments, referring to Figures 1, 2 and 4, the feeding bracket 11 includes: a fixed base 111, a first clamping roller mounting member 112 and a second clamping roller mounting member 113, wherein the material support drive member 21 is disposed on the fixed base 111, the first clamping roller mounting member 112 is slidably disposed on the fixed base 111 along a first direction (Z-axis direction in Figure 1), the first clamping roller 12 is rotatably disposed on the first clamping roller mounting member 112, the second clamping roller mounting member 113 is fixed on the fixed base 111, and the second clamping roller 13 is rotatably disposed on the second clamping roller mounting member 113.

[0132] By setting the first clamping roller mounting part 112 and the second clamping roller mounting part 113, the first clamping roller 12 and the second clamping roller 13 can each have a dedicated position for installation, thereby making the installation of the first clamping roller 12 and the second clamping roller 13 more convenient.

[0133] In addition, by making the first clamping roller mounting member 112 slidably disposed on the fixed base 111 along the first direction (Z-axis direction in FIG1), the width of the clamping slot 30 along the first direction can be adjusted. On the one hand, this allows the feeding mechanism 1 to adapt to material strips L of different thicknesses, thus improving compatibility. On the other hand, when it is necessary to insert the material strip L into the clamping slot 30, the width of the clamping slot 30 can be increased, thereby simplifying the work of inserting the material strip L into the clamping slot 30.

[0134] In some embodiments, referring to FIG1, the feeding mechanism 1 further includes a clamping drive assembly 14, which is disposed on the fixed base 111 and is used to drive the first clamping roller mounting member 112 to move toward or away from the second clamping roller mounting member 113 along a first direction.

[0135] By setting the clamping drive assembly 14, the clamping drive assembly 14 can automatically drive the first clamping roller mounting part 112 to move closer to or further away from the second clamping roller mounting part 113 along the first direction, thereby automatically achieving the purpose of adjusting the width of the clamping gap 30 along the first direction, with a higher degree of automation.

[0136] In some embodiments, referring to FIG1, the clamping drive assembly 14 includes a clamping drive member 141 and an elastic member 142. The clamping drive member 141 is disposed on the fixed base 111. A cam 1411 is disposed on the rotation shaft of the clamping drive member 141. The peripheral wall of the cam 1411 abuts against the first clamping roller mounting member 112 along a first direction (Z-axis direction in FIG1). The elastic member 142 is used to provide a spring force to the first clamping roller mounting member 112 to drive the first clamping roller mounting member 112 to move away from the second clamping roller mounting member 113 along the first direction (moving along the positive Z-axis direction in FIG1).

[0137] Since the peripheral wall of the cam 1411 abuts against the first clamping roller mounting member 112 along the first direction, when the clamping drive member 141 drives the rotating shaft to rotate, thereby causing the long shaft of the cam 1411 to rotate toward the first clamping roller mounting member 112, the cam 1411 can press the first clamping roller mounting member 112 toward the second clamping roller mounting member 113 along the first direction, thereby driving the first clamping roller mounting member 112 to move toward the second clamping roller mounting member 113 along the first direction.

[0138] When the short shaft of cam 1411 rotates toward the first clamping roller mount 112, the squeezing force of cam 1411 on the first clamping roller mount 112 disappears, and elastic member 142 can drive the first clamping roller mount 112 to move away from the second clamping roller mount 113 along the first direction.

[0139] As can be seen, through the cooperation between the cam 1411 and the elastic element 142, the rotational motion of the rotating shaft of the clamping drive 141 can be converted into the linear motion of the first clamping roller mounting part 112 along the first direction. In this way, when selecting the clamping drive 141, there is no need to select expensive linear motors, etc., and thus the cost of the clamping drive 141 can be reduced to a certain extent.

[0140] The clamping drive component 141 can be a servo motor or a stepper motor, etc., and this embodiment does not limit it.

[0141] In some embodiments, referring to FIG1, the fixed base 111 is provided with a guide hole 1111 extending through the fixed base 111 in a first direction. The first clamping roller mounting member 112 is provided with a guide rod 1121, which is slidably inserted through the guide hole 1111 in the first direction. The guide rod 1121 includes an exposed end 1121a that is away from the first clamping roller mounting member 112 and protrudes from the fixed base 111. An elastic member 142 is sandwiched between the fixed base 111 and the exposed end 1121a.

[0142] Since the guide rod 1121 is slidably inserted through the guide hole 1111 in the first direction, and the first clamping roller mounting member 112 is disposed on the guide rod 1121, the first clamping roller mounting member 112 can move more smoothly in the first direction under the cooperation of the guide rod 1121 and the guide hole 1111.

[0143] Furthermore, by clamping an elastic element 142 between the fixed seat 111 and the exposed end 1121a, when the clamping drive member 141 presses the first clamping roller mounting member 112 via the cam 1411 to drive the first clamping roller mounting member 112 to move in the first direction toward the second clamping roller mounting member 113, the elastic element 142 will be compressed. When the cam 1411 stops pressing the first clamping roller mounting member 112, the elastic element 142 will return to its original shape. During the process of the elastic element 142 returning to its original shape, it will push the first clamping roller mounting member 112 to move in the first direction away from the second clamping roller mounting member 113 via the exposed end 1121a.

[0144] There are multiple ways to implement the above-mentioned elastic element 142. In one possible implementation, the elastic element 142 is a spring, which is sleeved on the guide rod 1121.

[0145] By having the spring sleeved on the guide rod 1121, the guide rod 1121 can limit the spring and prevent it from tilting during compression.

[0146] Of course, in other possible implementations, the elastic element 142 can also be a spring sheet, etc., and this embodiment does not limit it.

[0147] In some embodiments, referring to FIG1, a roller 1122 is provided on the first clamping roller mounting member 112, the peripheral wall of the roller 1122 abuts against the peripheral wall of the cam 1411, and the rotation axis of the cam 1411 is parallel to the rotation axis of the roller 1122.

[0148] This configuration changes the friction between the cam 1411 and the first clamping roller mounting part 112 from sliding friction to rolling friction, thereby reducing the frictional force between the cam 1411 and the first clamping roller mounting part 112 to a certain extent. On the one hand, it can prevent the cam 1411 and / or the first clamping roller mounting part 112 from being damaged by friction. On the other hand, it is also more labor-saving for the clamping drive part 141. When selecting the model, a smaller clamping drive part 141 can be selected, thereby reducing the cost of the clamping drive part 141.

[0149] This disclosure also provides a structural schematic diagram of a battery cell winding device 200. Referring to Figure 3, the battery cell winding device 200 includes an insert device 100 and a winding needle 300. The winding needle 300 is located on a preset track G and downstream of the material support assembly 22. The material support drive 21 is used to drive the material support assembly 22 to move along the preset track G in a direction close to the winding needle 300 (the positive direction of the X-axis in Figure 3) to guide the head end L1 of the material strip L to the winding needle 300. The winding needle 300 is used to wind the material strip L around itself to produce a battery cell when rotating.

[0150] The structure of the insert device 100 can be the same as that of any of the insert devices 100 described in the above embodiments, and can bring the same or similar beneficial effects. This embodiment will not be described in detail here.

[0151] In this embodiment, since the insert device 100 can drive the material support assembly 22 to move towards the head end L1 (the positive direction of the X-axis in Figure 3) through the material support drive 21, the head end L1 of the strip L can be supported by the material support assembly 22. This prevents the head end L1 of the strip L from tilting up and deviating from the preset trajectory G, thus ensuring higher positional accuracy of the head end L1 after insertion into the winding needle 300. Based on this, when the winding needle 300 rotates to wind the strip L around itself to produce a battery cell, the quality of the battery cell is better.

[0152] In some embodiments, referring to Figures 6, 7, and 8, Figure 6 is a structural schematic diagram of another insert device 100 provided in an embodiment of the present disclosure, Figure 7 is a simplified structural schematic diagram of the insert device 100 in Figure 6 applied to a cell winding device 200, and Figure 8 is a simplified structural schematic diagram of the cell winding device 200 in Figure 7 after the feeding mechanism 1 moves along a preset trajectory G toward the winding needle 300. The insert device 100 further includes: an insert drive member 3, the feeding mechanism 1 is disposed on the insert drive member 3, and the insert drive member 3 is used to drive the feeding mechanism 1 to move along the preset trajectory G toward the winding needle 300 so as to insert the head end L1 into the winding needle 300.

[0153] Since the insert drive 3 can drive the feeding mechanism 1 to move along the preset trajectory G towards the direction of the winding needle 300, under the action of the insert drive 3, the material support assembly 22 can be directly inserted into the winding needle 300, thereby achieving the purpose of inserting the head end L1 position more accurately into the winding needle 300.

[0154] The aforementioned insert drive 3 can be any component or structure that can drive the feeding mechanism 1 to move along the preset trajectory G toward the direction of the winding needle 300, such as a cylinder, electric cylinder, or linear module. This embodiment does not limit this.

[0155] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
