Description

Technical Field

[0001] This utility model relates to the field of electrode conveying technology, and in particular to an electrode conveying device and an electrode composite equipment. Background Technology

[0002] In the production process of stacked batteries, an electrode conveying device is usually used to transport the battery electrodes to the composite roller for composite bonding.

[0003] In existing technologies, belt-driven conveying is commonly used for wide electrode sheets with a width greater than 500mm. Belt-driven conveying offers advantages such as high speed, simple structure, and low cost, and can be used to convey wide electrode sheets. Electrode conveying devices using belt-driven conveying typically include two opposing belts, each mounted on multiple conveyor rollers. To ensure conveying efficiency, the conveyor roller closest to the composite roller usually has a smaller diameter, allowing it to be closer to the composite position. However, since the length of all conveyor rollers must be greater than the width of the wide electrode sheet, the smaller-diameter rollers are prone to deformation under belt tension, affecting the conveying efficiency of the wide electrode sheets. Furthermore, deformed rollers require timely replacement, resulting in high maintenance costs. Utility Model Content

[0004] The first objective of this utility model is to provide an electrode conveying device with high conveying efficiency and low maintenance cost;

[0005] The second objective of this invention is to provide an electrode composite device that has a high composite effect and low maintenance cost.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] An electrode conveying device is provided, comprising:

[0008] Support frame;

[0009] The belt conveyor mechanism is provided in two sets. The belt conveyor mechanism includes multiple support shafts rotatably mounted on the support frame and belts wound around the multiple support shafts. The two belts are arranged opposite to each other and are used to clamp and convey the electrode. Among all the support shafts of each belt conveyor mechanism, the one located downstream in the electrode conveying direction is the end support shaft.

[0010] A rolling support assembly is disposed on the support frame and rolls to support the two end support shafts.

[0011] The beneficial effects of this utility model are:

[0012] The electrode conveying device and electrode composite equipment provided by this utility model typically use two belts to clamp and convey the electrodes, resulting in high conveying efficiency and a relatively simple structure. By setting a rolling support assembly, the end support shaft is provided with rolling support, thereby reducing the probability of bending deformation of the end support shaft, improving the reliability and stability of electrode conveying, ensuring the electrode conveying effect, and reducing the maintenance cost of the electrode conveying device. Furthermore, the rolling support assembly and the end support shaft do not affect the rotation of the end support shaft and will not affect the conveying of the electrodes. In addition, the friction between the rolling support assembly and the end support shaft is small, reducing wear on the end support shaft. Attached Figure Description

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Firstly, this embodiment provides an electrode conveying device for conveying electrode sheets, which can ensure the conveying effect and has low maintenance costs.

[0033] In this embodiment, the electrode conveying device is located upstream of the composite roller and downstream of the electrode cutting, and is used to convey the electrode to the composite roller. Specifically, the electrode conveying device conveys the positive electrode, the negative electrode, and the separator to the composite roller, so that the positive electrode, the negative electrode, and the separator can be composited at the composite roller.

[0034] like Figures 1 to 4 As shown, the electrode conveying device includes a support frame 100 and a belt conveyor mechanism 200 and a rolling support assembly 300, both of which are disposed on the support frame 100. The support frame 100 is used to support the belt conveyor mechanism 200 and the rolling support assembly 300.

[0035] Exemplarily, two belt conveyor mechanisms 200 are provided, for example, the two belt conveyor mechanisms 200 are arranged opposite each other in the second direction Z. In some optional embodiments, the second direction Z is a vertical direction. Each belt conveyor mechanism 200 includes a plurality of support shafts 210 rotatably disposed on the support frame 100 and a belt 220 wound around the plurality of support shafts 210. The axial direction of the support shafts 210 is the first direction Y, and the support shafts 210 are used to support the belt 220 so that the belt 220 can be in close contact with the electrode. In this embodiment, the belt 220 is a closed loop, and the continuous rotation of the belt 220 can continuously convey the electrode. In this embodiment, two belts 220 are provided, and the two belts 220 are arranged opposite each other in the second direction Z.

[0036] The electrode conveying device provided in this embodiment can be used to convey electrodes with a larger width. That is, the width of both belts 220 is larger, usually greater than the width of the electrode they convey, and the length of the support shafts 210 is also larger.

[0037] For example, the widths of the two belts 220 may be the same or different, and this embodiment does not limit this. In this embodiment, the two belts 220 are arranged opposite each other in the vertical direction (i.e., the second direction Z). Figure 2 As shown, the width of the bottom belt 220 is greater than the width of the top belt 220. This has two advantages: firstly, the wider bottom belt 220 reduces the likelihood of the electrode falling off, providing better protection; secondly, the narrower top belt 220 stably presses the electrode onto the bottom belt 220 and facilitates the detection of electrode misalignment, such as by a visual correction device, thus improving the stability and reliability of the transmission. The width direction of the belt 220 is the first direction Y.

[0038] In some optional embodiments, the positive and negative electrode plates are located on opposite sides of the separator, with the positive electrode plate in contact with one of the belts 220 and the negative electrode plate in contact with the other belt 220, such that the two belts 220 can drive the positive and negative electrode plates to move synchronously. In this embodiment, the positive electrode plate and the... Figure 2 The belt 220 located above the middle contacts the negative electrode plate. Figure 2 The belt 220 is located below the center.

[0039] In this embodiment, the two belts 220 are used to clamp and transport the electrode sheets. That is, the belts 220 drive the electrode sheets to move in the electrode sheet transport direction through the friction between the belts 220 and the electrode sheets. In this embodiment, the electrode sheet transport direction is the third direction X. Furthermore, as... Figure 4As shown, each belt conveyor mechanism 200 includes multiple support shafts 210, each of which includes an end support shaft 211 in the electrode conveying direction. It should be noted that among all the support shafts 210 of each belt conveyor mechanism 200, the one located furthest downstream in the electrode conveying direction is the end support shaft 211, that is, the end support shaft 211 is the support shaft 210 closest to the composite roller 10 among the multiple support shafts 210.

[0040] It should be noted that in this embodiment, the end support shaft 211 is relatively long and has a small diameter, allowing it to be positioned within the gap between the two composite rollers 10. This ensures that the end support shaft 211 is close to the composite position of the composite rollers 10, guaranteeing the stable and synchronous delivery of the positive and negative electrode sheets to the composite position. The support shafts 210, except for the end support shaft 211, can be thicker to provide higher resistance to deformation. The composite position of the composite rollers 10 is where the distance between the two composite rollers is minimized, and the electrode sheet and separator are composited at this position.

[0041] For example, in this embodiment, the length of the end support shaft 211 is 700mm-1000mm; for example, the length of the end support shaft 211 is 700mm, 800mm, 900mm, 1000mm, etc. The diameter of the end support shaft 211 is 10mm-20mm; for example, the diameter of the end support shaft 211 is 10mm, 12mm, 18mm, 20mm, etc.

[0042] For the thin and long end support shaft 211, this embodiment provides a rolling support assembly 300 for rolling support of the two end support shafts 211, thereby reducing the probability of bending deformation of the end support shaft 211, improving the reliability and stability of the electrode conveying, ensuring the electrode conveying effect, reducing the maintenance cost of the electrode conveying device, and the rolling support assembly 300 and the end support shaft 211 do not affect the rotation of the end support shaft 211 and do not affect the electrode conveying; in addition, the friction between the rolling support assembly 300 and the end support shaft 211 is small, reducing the wear on the end support shaft 211.

[0043] To improve the support effect on the two end support shafts 211, such as Figure 5 As shown, the rolling support assembly 300 includes two rolling support structures 310. Each rolling support structure 310 provides rolling support to its corresponding end support shaft 211, enabling each end support shaft 211 to achieve independent support. The position of the rolling support structure 310 can be set according to the force characteristics of each end support shaft 211 to ensure the rolling support effect.

[0044] In some alternative embodiments, please refer to Figure 5The two rolling support structures 310 are arranged opposite each other in the second direction Z. Of course, it can be understood that the two rolling support structures 310 can also be arranged at intervals in the first direction Y, but this embodiment does not limit this.

[0045] The rolling support structure 310 can have various specific structures. This embodiment provides a rolling support structure 310, such as... Figure 6 As shown, the rolling support structure 310 includes a connecting block 311, a connecting shaft 312, and rolling elements 313. The connecting block 311 has two protrusions 3111 spaced apart in the first direction Y. Specifically, the connecting block 311 has two protrusions 3111 on the side facing the end support shaft 211. The two connecting shafts 312 are spaced apart in the second direction Z. Each connecting shaft 312 is connected at both ends to the two protrusions 3111, thus fixing the two connecting shafts 312. At least one rolling element 313 is fitted onto each connecting shaft 312, and all rolling elements 313 on each connecting shaft 312 are in rolling contact with the corresponding end support shaft 211. This increases the contact area between the rolling support structure 310 and the end support shaft 211, ensuring effective support for the end support shaft 211 and reducing the risk of deformation of the end support shaft 211.

[0046] For example, the number of rolling elements 313 on the two connecting shafts 312 may be the same or different. In this embodiment, for instance... Figure 6 As shown, three rolling elements 313 are fitted on one connecting shaft 312, and two rolling elements 313 are fitted on another connecting shaft 312.

[0047] It should be noted that the rolling element 313 has a protrusion 3111 on the third direction X to ensure that the rolling element 313 contacts the end support shaft 211, while the protrusion 3111 does not contact the end support shaft 211.

[0048] To limit the position of the rolling element 313 on the connecting shaft 312, please refer to [link to relevant documentation]. Figure 6 A limiting sleeve 314 is provided on the connecting shaft 312. The limiting sleeve 314 is used to limit the position of the rolling element 313 in the first direction Y. That is, the limiting sleeve 314 is used to limit the position of the rolling element 313 relative to the connecting shaft 312, so as to avoid the rolling element 313 moving along the first direction Y and affecting the support effect on the end support shaft 211.

[0049] For example, when a rolling element 313 is provided on the connecting shaft 312, two limiting sleeves 314 are sleeved on the connecting shaft 312, and a limiting sleeve 314 is provided between each protrusion 3111 and the rolling element 313 to limit the movement of each rolling element 313. When multiple rolling elements 313 are provided on the connecting shaft 312, the multiple rolling elements 313 are spaced apart along the first direction Y, and a limiting sleeve 314 is provided between two adjacent rolling elements 313 and between the rolling element 313 and the protrusion 3111.

[0050] In some optional embodiments, the rolling element 313 is a bearing, which is sleeved on the connecting shaft 312, and the outer peripheral surface of the bearing is in rolling contact with the end support shaft 211. The bearing has a simple structure and can stably support the end support shaft 211 with high reliability.

[0051] In some other alternative embodiments, the rolling element 313 may also be a ball, roller, or the like that rotatably mounted on the connecting shaft 312, and this embodiment does not limit this.

[0052] Since the end support shaft 211 has a relatively large length in the first direction Y, while the rolling support structure 310 typically has a shorter length in the first direction Y, in order to further reduce the bending deformation of the end support shaft 211, such as... Figure 4 As shown, multiple sets of rolling support assemblies 300 are provided, and these multiple sets of rolling support assemblies 300 are spaced apart along the axial direction (i.e., the first direction Y) of the end support shaft 211 to provide a more uniform rolling support force to the end support shaft 211 and prevent the end support shaft 211 from deforming under the tension of the belt 220. For example, multiple rolling support assemblies 300 are evenly spaced along the first direction Y to further improve the support effect on the end support shaft 211. In this embodiment, there may be 2, 3, 4, or other rolling support assemblies 300.

[0053] During operation, the belt 220 may experience lateral deviation, meaning it may shift in the first direction Y. To prevent this shift, each support shaft 210 of the belt conveyor mechanism 200 includes at least one anti-deviation support shaft (not shown in the figure). In each belt conveyor mechanism 200, one of the belt 220 and the anti-deviation support shaft is provided with a groove 212, and the other with a rib 221. The rib 221 slides into the groove 212, fixing the relative position of the belt 220 and the anti-deviation support shaft in the first direction Y. This prevents the belt 220 from shifting in the first direction Y, avoiding lateral deviation and reducing the likelihood of misalignment between the positive and negative electrode plates, thus ensuring the effectiveness of electrode composite.

[0054] For example, such as Figure 4 and Figure 7 As shown, a groove 212 is provided on the anti-deviation support shaft, and a rib 221 is provided on the inner wall of the belt 220. The groove 212 extends in a ring shape along the circumference of the anti-deviation support shaft, and the rib 221 extends in a ring shape along the circumference of the belt 220, so that even if the anti-deviation support shaft rotates, the rib 221 can always slide in the groove 212, thereby limiting the position of the belt 220 relative to the anti-deviation support shaft during the rotation of the belt 220.

[0055] It should be noted that all support shafts 210 can be anti-deviation support shafts, that is, each support shaft 210, including the end support shaft 211, is provided with a groove 212 or a rib 221. This embodiment does not limit this.

[0056] In some optional embodiments, for a belt conveyor mechanism 200, multiple sets of grooves 212 and ribs 221 can be provided. Multiple sets of grooves 212 and ribs 221 are spaced apart along the width direction of the belt 220 to further reduce the probability of the belt 220 running laterally. This can be used to prevent the belt 220 from running off-center.

[0057] Optionally, such as Figure 3 and Figure 5 As shown, the belt conveyor mechanism 200 also includes a drive roller 230, which drives the belt 220 to rotate, thereby conveying the electrode sheets. The drive roller 230 is rotatably mounted on the support frame 100, and the belt 220 is wound around the drive roller 230. The surface of the drive roller 230 that contacts the belt 220 is an arc surface, and the surface of the drive roller 230 that contacts the belt 220 has a rough structure to increase the contact friction between the drive roller 230 and the belt 220 and improve the transmission efficiency.

[0058] For example, the roughening structure can be knurling, grooves, or other structures that can increase friction. The roughening structure can also be a silicone sleeve, rubber sleeve, etc., provided on the drive roller 230, but this embodiment does not limit this.

[0059] Optionally, such as Figure 1 and Figure 2 As shown, each belt conveyor mechanism 200 further includes a second drive member 600, which is driven and connected to the drive roller 230 and drives the drive roller 230 to rotate. When the drive roller 230 rotates, it can drive the belt 220 to move through the surface with a rough structure. The second drive member 600 is mounted on the support frame 100. Exemplarily, the second drive member 600 includes, but is not limited to, a motor.

[0060] In the electrode composite process, the conveying of the separator and the conveying of the electrode are independent of each other. For example, the separator is conveyed by a conveyor roller. In this embodiment, the conveying speed of the belt 220 is the same as the conveying speed of the separator, so that the separator and the belt 220 run synchronously, avoiding misalignment of the positive and negative electrode plates caused by speed differences, thereby improving the alignment of the positive and negative electrode plates. Exemplarily, the belt 220 can be a vacuum belt 220, which can adsorb the electrode plates to ensure the alignment of the positive and negative electrode plates. Furthermore, a visual correction device can be provided to further improve the alignment of the positive and negative electrode plates.

[0061] Further optional, such as Figure 5 As shown, each belt conveyor mechanism 200 also includes a traction roller 260, a tension roller 250, and a driven roller 240, all rotatably mounted on the support frame 100. Multiple support shafts 210 are sequentially spaced along a third direction X. The driving roller 230, tension roller 250, and driven roller 240 are located on one side of the multiple support shafts 210 in a second direction Z. The tension roller 250 and driven roller 240 are located on both sides of the driving roller 230 in the third direction X, and both are in contact with the outer surface of the belt 220. The traction roller 260 is located upstream of the multiple support shafts 210 in the third direction X. The traction roller 260 is used to pull the electrode plates, the tension roller 250 is used to adjust the tension of the belt 220, and the driven roller 240 and tension roller 250 cooperate to provide a larger contact area between the belt 220 and the driving roller 230, thereby further improving transmission efficiency.

[0062] It should be noted that the positions of the multiple support shafts 210 and the traction rollers 260 are such that the outer surface of the belt 220 between the traction rollers 260 and the end support shafts 211 is parallel to a plane in the third direction X, so that the belt 220 and the electrode are in surface contact, ensuring the flatness of the electrode during the conveying process.

[0063] Optionally, such as Figure 3 As shown, the electrode conveying device also includes a first drive unit 400. The support frame 100 includes two frames 110, which are arranged opposite each other in the second direction Z. Two belt conveyor mechanisms 200 correspond one-to-one with the two frames 110, with each belt conveyor mechanism 200 disposed on its corresponding frame 110. The first drive unit 400 is driven to one of the two frames 110 and is used to drive that frame 110 to move closer to or away from the other frame 110. When the two frames 110 move, they drive the belts 220 to move, allowing for a larger distance between the two belts 220. This facilitates operations such as changing electrodes, cleaning electrodes or debris between the two belts 220, and threading diaphragms, resulting in a high degree of automation. For example, the second drive unit 600 may include, but is not limited to, a cylinder or a linear motor.

[0064] Further optional, such as Figure 3 As shown, the second driving component 600 can be mounted on the mounting plate 700, which is fixed. The main body of the second driving component 600 is fixed on the mounting plate 700, and the output end of the second driving component 600 is connected to a frame 110. The mounting plate 700 can be slidably connected to the frame 110 via a connecting plate 120 to ensure the direction of movement and the stability of movement of the frame 110. For example, the mounting plate 700 and the connecting plate 120 are slidably connected via a matching slide rail slider, and the connecting plate 120 is connected to the frame 110.

[0065] It should be noted that when the support frame 100 includes two frames 110, the rolling support assembly 300 includes two rolling support structures 310. The two rolling support structures 310 are arranged one-to-one with the two frames 110, so that when the two frames 110 are separated, the two rolling support structures 310 move with the two frames 110.

[0066] To further improve the delivery effect to the electrode sheets, such as Figure 4 and Figure 5 As shown, the electrode conveying device also includes an auxiliary support 500. The auxiliary support 500 is connected to the support frame 100. When the support frame 100 includes two frames 110, the auxiliary support 500 is positioned on the lower frame 110. The auxiliary support 500 is located downstream of the belt conveyor mechanism 200 in the electrode conveying direction (i.e., the third direction X), meaning that the auxiliary support 500 is closer to the composite roller 10 than the end support shaft 211 of the belt conveyor mechanism 200. The auxiliary support 500 supports the electrode; specifically, it receives the electrode output by the belt 220 to prevent the electrode from bending under gravity after outputting from the belt 220 and before being composited by the composite roller 10, thus allowing the electrode to move smoothly to the composite position.

[0067] For example, such as Figure 9 As shown, the auxiliary support 500 extends toward the composite roller 10, and its thickness gradually decreases in the electrode conveying direction, so that the auxiliary support 500 can be as close as possible to the composite position to smoothly convey the electrode to the composite position. The thickness direction of the auxiliary support 500 is the second direction Z.

[0068] Secondly, this embodiment provides an electrode composite device with high composite effect and low maintenance cost. For example... Figure 8 and Figure 9 As shown, the electrode laminating equipment includes an electrode conveying device in the first aspect and two laminating rollers 10 arranged opposite each other in the second direction Z. The electrode conveying device is located on one side of the laminating rollers 10 and is used to convey the electrode to the laminating rollers 10 so that the electrode and the diaphragm are laminating at the laminating position.

[0069] For example, the orthographic projection of the end support shaft 211 in the second direction Z is located within the orthographic projection of the composite roller 10 in the second direction Z, making the end support shaft 211 closer to the composite position, which in turn makes the belt 220 closer to the composite position, and thus the electrode output belt 220 closer to the composite position. Since the belt 220's clamping and conveying can ensure the alignment of the positive and negative electrodes, the proximity of the electrode output belt 220 to the composite position can reduce the probability of misalignment between the positive and negative electrodes, ensuring the effectiveness of electrode composite.

[0070] Optionally, the electrode laminating equipment also includes a cutting device, which is located upstream of the electrode conveying device and is used to cut the electrode. The electrode conveying device transports the cut electrode to the laminating roller 10, where the two laminating rollers 10 laminate the electrode.

[0071] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
