Description

Technical Field

[0001] This utility model belongs to the field of microchannel production technology, specifically relating to microchannel conveying, and particularly to a conveying system and conveyor belt for microchannel production of lithium battery heat exchangers. Background Technology

[0002] In the production process of lithium battery heat exchangers, microchannels (usually long and flat aluminum structures) need to be surface-cleaned before packaging to ensure the quality of subsequent welding or assembly.

[0003] In related technologies, a conveyor belt system is used to transport microchannels to the cleaning drive roller position. However, due to the large length of the microchannels (e.g., exceeding 1 meter), the conveyor belt needs to have a long span. Due to the large conveying span, the drive roller is prone to generating periodic centrifugal force when rotating at high speed, causing the conveyor belt to deviate and triggering radial vibration. This causes the microchannel to deviate laterally during the conveying process, making it impossible to accurately position it to the cleaning drive roller position. The deviation of the microchannel may cause material jamming, which will seriously affect production efficiency and yield.

[0004] Therefore, how to prevent the microchannel from shifting during the delivery process is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information on the bearing surface disclosed in this background section is only used to understand the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least a conveying system and conveyor belt for producing microchannels using lithium battery heat exchangers, in order to solve the technical problem of microchannels shifting during transport.

[0007] In a first aspect, embodiments of this disclosure provide a conveying system for microchannel production of lithium battery heat exchangers, comprising: a driving device including a pair of driving rollers; a conveyor belt body driven by the driving rollers, wherein elastic limiting structures are respectively provided on both sides of the conveyor belt body to limit the microchannel between the two limiting structures of the conveyor belt body; the limiting structure includes a material support portion located on the side of the conveyor belt body and a guide strip located on the back of the material support portion; wherein the two guide strips are respectively embedded in the guide ring grooves on both sides of the driving rollers to prevent the conveyor belt body from deviating.

[0008] In one alternative embodiment, the thickness of the material support portion gradually decreases from the edge of the conveyor belt body towards the center of the conveyor belt body.

[0009] In one optional embodiment, the upper end face of the material support portion is concave arc-shaped and gradually increases in height from the inside to the outside.

[0010] In one optional embodiment, the material support portion is stepped, with progressively increasing steps from the inside out.

[0011] In one optional embodiment, a wavy baffle strip is provided on the material support part along its length direction, which is suitable for increasing the frictional resistance between the microchannel and the material support part.

[0012] In one optional embodiment, the material support and guide strip have a hardness of 60-75 Shore A.

[0013] Secondly, this disclosure also provides a conveyor belt, including: a conveyor belt body, wherein elastic limiting structures are respectively provided on both sides of the conveyor belt body to limit the microchannel between the two limiting structures of the conveyor belt body; the limiting structure includes a material support portion located on the side of the conveyor belt body and a guide strip located on the back of the material support portion; wherein the two guide strips are respectively embedded in the guide ring grooves on both sides of the drive roller to prevent the conveyor belt body from deviating; a wavy resistance strip is provided on the material support portion along the length direction, which is suitable for increasing the frictional resistance between the microchannel and the material support portion.

[0014] In one alternative embodiment, the material support portion is concave arc-shaped, which is used to adapt to microchannels with a groove-shaped cross-section.

[0015] In one alternative implementation, the material support portion is stepped, which is used to adapt to microchannels with rectangular cross-sections.

[0016] In one alternative embodiment, the hardness of the material support portion is 60-75 Shore A.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a conveying system for microchannel production of lithium battery heat exchangers. By setting guide strips on both sides of the conveyor belt body, the central axis of the conveyor belt body and the drive roller are always aligned, eliminating radial offset during rotation and fundamentally avoiding conveyor belt vibration. In addition, by setting up material support parts, the microchannel is confined between two material support parts, forming resistance to the lateral movement of the microchannel. This not only solves the problem of lateral slippage of the microchannel caused by inertia or vibration, but also maintains the overall stability of the system through a dynamic correction mechanism, thereby ensuring the positional accuracy of the microchannel during high-speed conveying and reducing the product defect rate.

[0036] Research has revealed the following drawbacks of existing technologies: In related technologies, a conveyor belt system is used to transport microchannels to the cleaning drive roller position. However, due to the large length of the microchannels (e.g., exceeding 1 meter), the conveyor belt needs to have a long span. Because of the large conveying span, the drive roller is prone to generating periodic centrifugal force when rotating at high speed, causing the conveyor belt to deviate and triggering radial vibration. This causes the microchannels to deviate laterally during the conveying process, making it impossible to accurately position them to the cleaning drive roller position. The deviation of the microchannels may cause material jamming, which will seriously affect production efficiency and yield.

[0037] Therefore, how to prevent the microchannel from shifting during the delivery process is a technical problem that urgently needs to be solved in this field.

[0038] The defects in the proposed solutions on the bearing surface are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the inventor to this disclosure.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] like Figures 1 to 5 As shown, this embodiment provides a conveying system for microchannel production of lithium battery heat exchangers, including: a drive device 1, which includes a pair of drive rollers 11. The drive device 1 is, but is not limited to, a motor. The motor is connected to one of the drive rollers 11. The rotation of this drive roller 11 drives the other drive roller 11 to rotate through the conveyor belt body 2, thereby changing the position of the material on the conveyor belt body 2. The conveyor belt body 2 is driven by the drive rollers 11. In order to avoid the lateral displacement of the material on the conveyor belt body 2, elastic limiting structures 3 are respectively provided on both sides of the conveyor belt body 2 to limit the microchannel 4 between the two limiting structures 3 of the conveyor belt body 2. It should be further noted that the hardness of the material support part 31 and the guide strip 32 is 60-75 Shore A.

[0042] The following describes the composition of the limiting structure 3. The limiting structure 3 includes a material support part 31 located on the side of the conveyor belt body 2 and a guide strip 32 located on the back of the material support part 31. The material support part 31 is used to support the microchannel 4, and the guide strip 32 is used to limit the conveyor belt body 2 on the drive roller 11. The two guide strips 32 are respectively embedded in the guide ring grooves 12 on both sides of the drive roller 11 to prevent the conveyor belt body 2 from deviating. By setting the guide strips 31 on both sides of the conveyor belt body 2, the central axis of the conveyor belt body 2 and the drive roller 11 are always aligned, eliminating radial deviation during rotation and fundamentally avoiding conveyor belt vibration. In addition, by setting the material support part 31, the microchannel 4 is restricted between the two material support parts 31, forming resistance to the lateral movement of the microchannel 4. This not only solves the problem of lateral slippage of the microchannel 4 caused by inertia or vibration, but also maintains the overall stability of the system through a dynamic correction mechanism, thereby ensuring the positional accuracy of the microchannel in high-speed conveying and reducing the product defect rate.

[0043] The thickness of the material support section 31 gradually decreases from the edge of the conveyor belt body 2 toward the center of the conveyor belt body 2; specifically, the upper end face of the material support section 31 is concave arc-shaped and gradually increases from the inside to the outside, in order to adapt to the microchannels 4 with arc-shaped cross-sections on both sides; or the material support section 31 is stepped and has gradually increasing steps from the inside to the outside, in order to adapt to the microchannels 4 with rectangular cross-sections.

[0044] To further enhance the stability of the microchannel 4 during the conveying process, a wavy baffle strip 33 is provided along the length of the material support 31. This baffle strip is suitable for increasing the frictional resistance between the microchannel 4 and the material support 31. Some of the wavy baffle strips 33 are used to directly abut against the bottom surface of the microchannel 4 (some of the wavy baffle strips 33 are deformed under the microchannel 4) to increase the contact friction of the bottom surface. Two rows of wavy baffle strips 33 abut against the two sides of the microchannel 4 respectively to enhance the resistance to lateral movement. The height of the wavy baffle strips 33 is 1 / 4 to 1 / 3 of the thickness of the microchannel 4.

[0045] This embodiment provides a conveyor belt, including: a conveyor belt body 2, with elastic limiting structures 3 respectively provided on both sides of the conveyor belt body 2 to limit the microchannel 4 between the two limiting structures 3; the limiting structure 3 includes a material support part 31 located on the side of the conveyor belt body 2 and a guide strip 32 located on the back of the material support part 31; wherein, the two guide strips 32 are respectively embedded in the guide ring grooves 12 on both sides of the drive roller 11 to prevent the conveyor belt body 2 from deviating; a wavy resistance strip 33 is provided on the material support part 31 along the length direction, which is suitable for increasing the frictional resistance between the microchannel 4 and the material support part 31.

[0046] The material support portion 31 is concave arc-shaped, designed to fit the microchannel 4 with a groove-shaped cross-section. The material support portion 31 is also stepped, designed to fit the microchannel 4 with a rectangular cross-section. The hardness of the material support portion 31 is 60-75 Shore A.

[0047] In summary, this invention, by setting guide strips 31 on both sides of the conveyor belt body 2, ensures that the central axis of the conveyor belt body 2 and the drive roller 11 are always aligned, eliminating radial offset during rotation and fundamentally preventing conveyor belt vibration. In addition, by setting material support parts 31, the microchannel 4 is confined between the two material support parts 31, forming resistance to the lateral movement of the microchannel 4. This not only solves the problem of lateral slippage of the microchannel 4 caused by inertia or vibration, but also maintains the overall stability of the system through a dynamic correction mechanism, thereby ensuring the positional accuracy of the microchannel during high-speed conveying and reducing the product defect rate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
