Description

Technical Field

[0001] This application relates to the field of electroplating equipment technology, and more particularly to a conveying device. Background Technology

[0002] Electroplating of solar cell grid lines is an important technology in solar cell manufacturing. It utilizes electrolysis to deposit copper or other metals onto the surface of the solar cell to form highly conductive grid lines, thereby collecting charge carriers generated by the photovoltaic effect. In the production process, electroplating involves hanging the solar cells on a rack and using a conveyor device to guide the rack and cells into the electroplating solution, where they move and are electroplated.

[0003] Because electroplating production lines are relatively long, the conveyor chains in related technologies need to be segmented, with gaps between the segments. The hangers need to cross from the first segment to the second. To ensure a continuous transition, the hanger conveyor includes a pushing mechanism that rapidly propels the hangers across the chain. However, this rapid movement causes significant fluctuations in the electroplating solution surface, resulting in splashes onto the hangers and hindering a smooth transition. Consequently, this leads to a higher defect rate for the electroplated solar cells. Utility Model Content

[0004] This application discloses a conveying device that enables a smooth transition of the hanger from the first chain segment to the second chain segment. This avoids large fluctuations in the surface of the electroplating solution caused by the rapid movement of the hanger, which could lead to the electroplating solution splashing onto the hanger and reduce the defect rate of the electroplated battery cells.

[0034] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0035] This application provides a conveying device including a hanger, a conveying track, a first transmission assembly, a second transmission assembly, and a third transmission assembly. The hanger is used to carry battery cells. The conveying track extends along a first direction and is slidably engaged with the hanger. The first transmission assembly includes a first conveyor, and the second transmission assembly includes a second conveyor. Both the first and second conveyors extend along the first direction and are located on one side of the conveying track, with a preset interval between them along the first direction.

[0056] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] See Figure 1 , Figure 1 This is a side view of the conveying device disclosed in an embodiment of this application. One embodiment of this application discloses a conveying device 100 for transporting battery cells. Specifically, the conveying device 100 includes a hanger 1, a conveying track 2, a first transmission assembly 3, a second transmission assembly 4, and a third transmission assembly 5. The hanger 1 carries the battery cells. The conveying track 2 extends along a first direction X and is slidably engaged with the hanger 1. The first transmission assembly 3 includes a first conveying member 31, which extends along the first direction X and is configured to apply a conveying force to the hanger 1. The second transmission assembly 4 includes a second conveying member 41, which extends along the first direction X. The second transmission component 41 and the first transmission component 31 are located on one side of the conveying track 2, and the second transmission component 41 and the first transmission component 31 have a preset interval L along the first direction X. The second transmission component 41 is configured to apply a conveying force to the hanger 1. The third transmission component 5 includes a third transmission component 51, which extends along the first direction X and is set at a preset interval L. The third transmission component 51 and the first transmission component 31 are located on both sides of the conveying track 2. The third transmission component 51 is configured to apply a conveying force to the hanger 1 so that the hanger 1 is conveyed from the first transmission component 31 to the second transmission component 41.

[0058] Wherein, the first direction X refers to the direction in which the hanger 1 is conveyed on the conveyor track 2, that is... Figure 1 The direction from left to right inside.

[0059] It is worth noting that the preset interval L between the first conveyor 31 and the second conveyor 41 along the first direction X means that the first conveyor 31 and the second conveyor 41 are arranged parallel to each other along the direction in which the hanger 1 is conveyed on the conveying track 2, and there is a preset interval L between the first conveyor 31 and the second conveyor 41. The reason for the preset interval L between the first conveyor 31 and the second conveyor 41 is that in the electroplating process, the hanger 1 is placed on the conveying track 2, which runs through the entire electroplating process line. The conveyor needs to provide conveying force to the hanger 1 so that the hanger 1 is on the conveying track 2. However, in actual operation, if the coverage length of the conveyor completely covers the conveying track 2, the conveying force provided by the conveyor to the hanger 1 will be unstable, which will cause the hanger 1 to occasionally break in its sliding on the conveying track 2. This will cause the hanger 1, carrying the battery cell, to sway back and forth in the electroplating solution, making the surface of the electroplating solution fluctuate and affecting the quality of the electroplated battery cell. Therefore, the first conveyor 31 and the second conveyor 41, which are set in parallel and have a preset interval L, are needed to ensure the stable transmission of the hanger 1 on the conveying track 2. In addition, the preset interval L is also set to ensure that the structures on the first conveyor 31 and the second conveyor 41 that are in contact with the hanger 1 will not interfere with each other as the conveyor moves along the first direction X.

[0060] In this way, on the one hand, the coordinated action of the first conveyor 31, the second conveyor 41, and the third conveyor 51 ensures the stable and efficient movement of the hanger 1 carrying the battery cells on the conveying track 2. The first conveyor 31 and the second conveyor 41 are located on opposite sides of the conveying track 2, which helps reduce the swaying of the hanger 1 during transport and improves the smoothness of the transport. At the same time, the third conveyor 51 further enhances the continuity of the transport, ensuring that the hanger 1 can smoothly transition from the first conveyor 31 to the second conveyor 41, reducing pauses and waiting time, and improving overall transport efficiency. On the other hand, since the third conveyor 51 is set according to the preset interval L, it means that it can precisely control the transfer process of the hanger 1 from the first conveyor 31 to the second conveyor 41. This avoids the situation where the hanger 1 needs to be pushed to transfer it from the first conveyor 31 to the second conveyor 41, and the hanger 1 swings in the electroplating solution due to the sudden rapid movement of the hanger 1. This avoids the fluctuation of the electroplating solution surface and prevents the electroplating solution from splashing onto the hanger 1 due to the swing of the hanger 1, thereby ensuring the smooth progress of the electroplating process and reducing the defect rate of the electroplated battery cells.

[0061] Furthermore, such as Figure 1As shown, the first conveyor 31 and the third conveyor 51 have a first overlapping area M along the second direction Y. When the hanger 1 is located on the conveying track 2 at the position corresponding to the first overlapping area M, the first conveyor 31 and the third conveyor 51 jointly apply a conveying force along the first direction X to the hanger 1. The second conveyor 41 and the third conveyor 51 have a second overlapping area N along the second direction Y. When the hanger 1 is located on the conveying track 2 at the position corresponding to the second overlapping area N, the second conveyor 41 and the third conveyor 51 jointly apply a conveying force along the first direction X to the hanger 1. That is to say, the first conveyor 31 and the third conveyor 51 have overlapping parts in the second direction Y, namely the first overlapping area M, and the second conveyor 41 and the third conveyor 51 have overlapping parts in the second direction Y, namely the second overlapping area N. When the hanger 1 is in the first overlapping area M on the conveying track 2, the first conveyor 31 and the third conveyor 51 jointly apply a conveying force along the first direction X to the hanger 1. When the hanger 1 is in the second overlapping area N on the conveying track 2, the second conveyor 41 and the third conveyor 51 jointly apply a conveying force along the first direction X to the hanger 1.

[0062] Wherein, the second direction Y is the direction perpendicular to the first direction X, that is... Figure 1 The direction from top to bottom or from bottom to top.

[0063] Thus, in the first overlapping region M, the hanger 1 is provided with conveying force by the first conveyor 31 and the third conveyor 51, and in the second overlapping region N, the hanger 1 is provided with conveying force by the second conveyor 41 and the third conveyor 51. This design ensures that the hanger 1 receives continuous and stable conveying force on the conveying track 2, improving overall transmission efficiency. Furthermore, when the hanger 1 is located in the overlapping region M or N, the conveying force is applied jointly by two conveyors (such as the first conveyor 31 and the third conveyor 51, or the second conveyor 41 and the third conveyor 51). This dual action not only increases the driving force but also improves the stability of transmission by distributing the load, helping to reduce problems such as vibration, deviation, or damage caused by uneven force or overload of a single conveyor.

[0064] In some embodiments, such as Figure 1 As shown, the first transmission assembly 3 also includes two first sprockets 32, a first pusher 33, and a first drive member 34. The first transmission member 31 includes a first chain. The two first sprockets 32 are arranged at intervals along a first direction X. The first chain is wound around the first sprockets 32. The portion of the first sprockets 32 near the conveying track 2 moves along the first direction X. The first pusher 33 is disposed on the surface of the first chain away from the first sprockets 32. The first pusher 33 is configured to push the hanger 1. The first drive member 34 is connected to one of the two first sprockets 32 and is configured to drive the first sprocket 32 ​​to rotate along a first rotation direction.

[0065] Wherein, the first rotation direction is Figure 1 Inward clockwise direction.

[0066] Thus, a stable and efficient transmission path is formed by two first sprockets 32 spaced apart along the first direction X and a first chain wound around them. This chain drive method ensures that the hanger 1 carrying the battery cells moves smoothly and continuously along the predetermined path, reducing stagnation and vibration during transmission and improving overall transmission efficiency. Simultaneously, the transmission connection between the first drive member 34 and one of the first sprockets 32 allows the entire chain drive system to operate precisely under control. By adjusting the output of the first drive member 34, the speed and direction of the chain can be easily controlled, thereby achieving precise transmission of the hanger 1 and the battery cells it carries. Furthermore, the chain drive system is relatively stable during operation and is less prone to slippage or detachment. Meanwhile, the first pusher 33 is located on the surface of the first chain away from the sprockets. This design allows the pusher to act directly on the hanger 1 without requiring complex mechanical conversion. Since the first pusher 33 acts directly on the hanger 1, the risk of failure in intermediate links is reduced, further improving the safety performance of the device.

[0067] Optionally, such as Figure 1 As shown, the second transmission assembly 4 further includes two second sprockets 42, a second pushing part 43, and a second driving member 44. The two second sprockets 42 are arranged at intervals along a first direction X. The second transmission member 41 includes a second chain, which is wound around the second sprockets 42. The portion of the second chain near the conveying track 2 moves along the first direction X. The second pushing part 43 is disposed on the surface of the second chain away from the second sprockets 42 and is configured to push the hanger 1 to move. The second driving member 44 is connected to one of the two second sprockets 42 and is configured to drive the second sprocket 42 to rotate along a first rotation direction. The first rotation direction is... Figure 1 The inner clockwise direction, that is, the rotation direction of the second sprocket 42 is the same as the rotation direction of the first sprocket 32.

[0068] Thus, similar to the first transmission assembly 3, the second transmission assembly 4, through two second sprockets 42 spaced apart along the first direction X and a second chain wound around them, forms a stable and efficient transmission path, ensuring that the hanger 1 can move quickly and smoothly along the predetermined path. Furthermore, since both the first transmission assembly 3 and the second transmission assembly 4 employ chain drive and are spaced apart along the first direction X, their operation can maintain a high degree of synchronicity. This parallel and synchronous transmission method helps reduce the offset and vibration of the hanger 1 during transmission, further improving the stability and accuracy of the transmission. In addition, the second drive member 44 controls the rotation of the second sprocket 42, and the first drive member 34 controls the rotation of the first sprocket 32, allowing the two transmission assemblies to be controlled independently and flexibly adjusted and optimized according to production needs. The second pusher 43 has the same structure and function as the first pusher 33, and will not be described in detail here.

[0069] In some embodiments, such as Figure 1 As shown, the third transmission assembly 5 further includes two third sprockets 52, which are spaced apart along the first direction X. The third transmission member 51 includes a third chain wound around the third sprockets 52. A third pushing part 53 is provided on the surface of the third chain away from the third sprockets 52. The third pushing part 53 is configured to push the hanger 1 to move. One of the two third sprockets 52 is connected to either a first sprocket 32 ​​or a second sprocket 42, so that the third sprocket 52 rotates along a second rotation direction. The diameters of the first sprocket 32, the second sprocket 42, and the third sprocket 52 are all the same. The second rotation direction is the opposite of the first rotation direction, i.e. Figure 1 Inward counterclockwise direction.

[0070] In this way, one of the two third sprockets 52 is connected to either a first sprocket 32 ​​or a second sprocket 42. This connection method ensures that the driving force for the rotation of the third sprocket 52 is transmitted from the second sprocket 42 or the first sprocket 32, enabling the third sprocket 52 to start or stop simultaneously with the first sprocket 32 ​​or the second sprocket 42. Furthermore, the first sprocket 32, the second sprocket 42, and the third sprocket 52 all have the same diameter, meaning they have the same speed ratio when transmitting power. This helps maintain the stability and consistency of the entire transmission system, ensuring that the speeds of the first sprocket 32, the second sprocket 42, and the third sprocket 52 are all the same, thereby ensuring that the transmission speed of the hanger 1 is always the same, guaranteeing the stability of the hanger 1's transmission.

[0071] It is worth noting that the sprockets and chains in the first transmission assembly 3, the second transmission assembly 4, and the third transmission assembly 5 described above can also be pulleys and belts, with the belt wrapped around the pulley and the pushing part disposed on the surface of the belt away from the pulley. This embodiment does not limit this.

[0072] The first driving component 34 and the second driving component 44 can be a motor, a cylinder, or other components that can provide power; this embodiment does not specifically limit them.

[0073] Furthermore, such as Figure 1 As shown, the second transmission assembly 4 also includes a first transmission gear 45, which is fixedly disposed with the second sprocket 42. The third transmission assembly 5 also includes a second transmission gear 54 and a driven gear 55, which is fixedly disposed with the third sprocket 52. The second transmission gear 54 and the driven gear 55 are externally meshed, and the second transmission gear 54 is connected to the first transmission gear 45 for transmission, so that the third sprocket 52 rotates in the second rotation direction. The diameters of the first transmission gear 45, the second transmission gear 54 and the driven gear 55 are all the same.

[0074] In this way, the transmission connection between the first transmission gear 45 and the second transmission gear 54 enables the synchronous start and stop of the second sprocket 42 and the third sprocket 52, ensuring the precise transmission of power from the second transmission assembly 4 to the third transmission assembly 5. The external meshing of the second transmission gear 54 and the driven gear 55 ensures that the rotation direction of the third sprocket 52 is opposite to that of the second sprocket 42. At the same time, since the diameters of the first transmission gear 45, the second transmission gear 54, and the driven gear 55 are all the same, their transmission ratios remain consistent, which helps to achieve synchronous movement between the two transmission assemblies and ensures that the hanger 1 moves stably along the first direction X on the conveying track 2 under the action of the transmission assemblies.

[0075] Optionally, such as Figure 1 As shown, there are multiple first pushing parts 33, which are spaced apart, with the same spacing between two adjacent first pushing parts 33 and corresponding to the spacing between two hangers 1; there are multiple second pushing parts 43, which are spaced apart, with the same spacing between two adjacent second pushing parts 43 and corresponding to the spacing between two hangers 1; there are multiple third pushing parts 53, which are spaced apart, with the same spacing between two adjacent third pushing parts 53 and corresponding to the spacing between two adjacent hangers 1.

[0076] In some embodiments, see Figure 1 and Figure 2 The conveying device 100 also includes a support member 6 and a lifting assembly 7. The lifting assembly 7 is disposed on the support member 6 and is connected to the third transmission assembly 5 so that the third transmission assembly 5 can move along the second direction Y. In this way, the lifting assembly 7 drives the third transmission assembly 5 to move along the second direction Y. When the first transmission assembly 3 or the second transmission assembly 4 malfunctions, the movement of the third transmission assembly 5 along the second direction Y facilitates the replacement or maintenance of the first transmission assembly 3 and the second transmission assembly 4.

[0077] Furthermore, such as Figure 1 As shown, the lifting assembly 7 includes a slide rail 71, which is disposed on the support member 6. The third transmission assembly 5 is slidably connected to the slide rail 71, allowing the third transmission assembly 5 to slide relative to the support member 6 along the second direction Y. This sliding connection between the third transmission assembly 5 and the slide rail 71 allows the third transmission assembly 5 to slide freely relative to the support member 6 along the second direction Y, and under the guidance of the slide rail 71, the third transmission assembly 5 can maintain a stable motion trajectory. Furthermore, compared to other complex transmission mechanisms, the sliding connection design is generally simpler and more compact, helping to reduce the overall complexity and manufacturing cost of the system.

[0078] Optionally, such as Figure 1 and Figure 2 As shown, the lifting assembly 7 also includes a lifting drive 72, which is connected to the third transmission assembly 5. The lifting drive 72 is configured to drive the third transmission assembly 5 to move along the second direction Y. Thus, the introduction of the lifting drive 72 enables automated control of the third transmission assembly 5 along the second direction Y. This eliminates the tedium and uncertainty of manual operation and improves the automation level of the production process. Automated control allows the third transmission assembly 5 to respond quickly and accurately to commands and move in the specified direction, thereby improving the overall system operating efficiency. Compared to manual operation or simple mechanical transmission methods, automated control reduces errors caused by human factors or mechanical wear, improving the stability and reliability of the system.

[0079] It should be noted that the lifting drive component 72 can be a motor, cylinder or other component that can provide driving force, and this embodiment does not specifically limit it.

[0080] In some embodiments, see Figure 3 and Figure 4 The hanger 1 includes a first transmission part 11 and a second transmission part 12. The first transmission part 11 and the second transmission part 12 are disposed at both ends of the hanger 1 along the second direction Y. The first transmission part 11 is configured to receive the conveying force applied by the first transmission member 31 or the second transmission member 41, and the second transmission part 12 is configured to receive the conveying force applied by the third transmission member 51.

[0081] In this way, the first transmission unit 11 and the second transmission unit 12 are located at opposite ends of the hanger 1, allowing the hanger 1 to distribute the conveying forces from different conveying components more evenly, thereby enhancing the overall stability of the hanger 1. Due to the balanced force distribution, the vibration generated by the hanger 1 during movement is also reduced, which is beneficial for protecting the battery cells on the hanger 1, improving processing accuracy, and extending the hanger's service life. Simultaneously, when the first transmission unit 11 and the second transmission unit 12 receive conveying forces from different conveying components at the same time, they can work together to achieve synchronous conveying of the hanger 1. This helps reduce waiting time and stagnation during the conveying process, improving conveying efficiency. Furthermore, by distributing the force and enhancing stability, the risks generated by the hanger 1 during operation are also correspondingly reduced.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 application.
