Abstract
Description
Technical Field
[0001] This utility model belongs to the field of microchannel production technology, specifically relating to microchannel clamping equipment, and more particularly to clamping components and packaging devices for microchannels of lithium battery heat exchangers. Background Technology
[0002] In the production process of lithium battery heat exchangers, the microchannel (usually a long and flat aluminum structure) strip production process typically includes cutting, surface treatment and assembly. During the packaging process, after multiple strip microchannels are stacked, wrapped and fixed, they need to be placed on a conveying device by a clamping component and then transported to the designated quality inspection station and packaging station.
[0003] In related technologies, mechanical gripping devices have gradually become the core equipment for transfer in microchannel production lines. These devices control the opening and closing of the grippers through drive mechanisms (such as cylinders and motors), enabling the gripping, lifting, translation, and release of strip-shaped microchannels, thereby completing automated transfer between production lines.
[0004] However, the grippers of existing gripping devices mostly use rigid structures (such as metal claw teeth and hard plastic clamps). During repeated gripping, the direct contact between the grippers and the surface of the microchannel is prone to problems such as uneven distribution of gripping force, excessive local pressure, or sharp edges of the grippers, which can lead to fine scratches, pits, or even coating damage on the surface of the microchannel. Such surface defects not only affect the appearance quality of the microchannel, but may also reduce its corrosion resistance, thereby leading to a decrease in product yield (industry statistics show that the scrap rate of microchannels due to surface damage can reach 3%-5%).
[0005] Therefore, how to avoid damage to the surface of the microchannel by the grippers is a technical problem that urgently needs to be solved in this field.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0007] This disclosure provides at least one microchannel gripping component and packaging device for a lithium battery thermal exchanger to solve the technical problem of damage to the microchannel surface caused by the grippers.
[0008] In a first aspect, embodiments of this disclosure provide a clamping assembly for a microchannel of a lithium battery heat exchanger, comprising: a lifting connecting frame, which is rigidly connected by a sliding joint and capable of driving the lifting connecting frame to perform three-dimensional spatial positioning and movement along the vertical and horizontal directions; a fixed ear assembly, comprising at least three pairs of symmetrically distributed fixed ear seats, which are installed on the two side facades of the lifting connecting frame; a clamping mechanism, wherein each fixed ear seat is equipped with a set of clamping units, the clamping unit comprising: two oppositely arranged clamping members, the two clamping members being connected by a telescopic mechanism; and roller guide portions, which are evenly distributed on the supporting portions of the clamping members.
[0009] In one optional embodiment, the clamping element includes vertical holding rods that are slidably mounted on a fixed lug and connected to a telescopic mechanism; wherein, the two vertical holding rods move toward each other or toward each other through the telescopic mechanism to lock onto both sides of the microchannel.
[0010] In one optional embodiment, an elastic buffer strip is provided on one side of the vertical holding rod, which is arranged along the length direction of the vertical holding rod.
[0011] In one alternative embodiment, the elastic buffer strip is provided with a V-shaped groove along its length, and the two inclined surfaces formed therein are suitable for squeezing both sides of the microchannel.
[0012] In one optional embodiment, the bottom of the vertical holding rod is fixed with a supporting part, and the supporting parts in a clamping unit are arranged facing each other; the roller guide is rotatably connected to the supporting part.
[0013] In one alternative embodiment, the arcuate surface of the roller guide extends above the supporting portion.
[0014] In one alternative embodiment, the lifting portion includes a shovel head adapted to abut against the bottom surface of the lowest microchannel; and the shovel head has a bevel.
[0015] In one alternative embodiment, the lifting portion further includes a support block fixed to the bottom of the vertical pressure rod.
[0016] In one alternative implementation, the support block and the shovel head are connected by an arc-shaped transition section.
[0017] Secondly, this disclosure also provides a packaging device, including: a conveying device and a clamping component as described above, the clamping component being disposed above the conveying device.
[0018] The beneficial effects of this utility model are that it provides a clamping component and packaging device for microchannels of lithium battery heat exchangers.

[0036] Research has revealed the shortcomings of existing technologies: mechanical gripping devices are gradually becoming the core equipment for transfer in microchannel production lines. These devices control the opening and closing of the grippers through drive mechanisms (such as cylinders and motors), enabling the gripping, lifting, translation, and release of strip-shaped microchannels, thereby completing automated transfer between production lines.
[0037] However, the grippers of existing gripping devices mostly use rigid structures (such as metal claw teeth and hard plastic clamps). During repeated gripping, the direct contact between the grippers and the surface of the microchannel is prone to problems such as uneven distribution of gripping force, excessive local pressure, or sharp edges of the grippers, which can lead to fine scratches, pits, or even coating damage on the surface of the microchannel. Such surface defects not only affect the appearance quality of the microchannel, but may also reduce its corrosion resistance, thereby leading to a decrease in product yield (industry statistics show that the scrap rate of microchannels due to surface damage can reach 3%-5%).
[0038] Therefore, how to avoid damage to the surface of the microchannel by the grippers is a technical problem that urgently needs to be solved in this field.
[0039] The shortcomings of the above solutions are the result of the utility model inventor's practice 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 utility model inventor to this disclosure.
[0040] 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.
[0041] 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.
[0042] like Figures 1 to 3As shown, some embodiments provide a clamping assembly for a microchannel of a lithium battery heat exchanger, including: a lifting connecting frame 1, which is rigidly connected by a sliding joint and can drive the lifting connecting frame 1 to perform three-dimensional spatial positioning and movement in the vertical and horizontal directions. Similar to related technologies, the sliding joint is a three-dimensional moving device used to control the overall vertical and horizontal movement of the lifting connecting frame 1; a fixed ear seat 2 assembly, including at least three pairs of symmetrically distributed fixed ear seats 2, which are installed on the two side facades of the lifting connecting frame 1; and a clamping mechanism, on which a set of clamping units are installed in each fixed ear seat 2. The clamping unit includes: two clamping parts 4 arranged opposite to each other, and the two clamping parts 4 are connected by a telescopic mechanism 3.
[0043] It should be further explained that multiple fixed ear seats 2 are evenly distributed on both sides of the lifting connecting frame 1. Two fixed ear seats 2 facing each other are a pair, used to clamp the two ends of a set of wound microchannels 5 (multiple stacked and wound microchannels 5); each fixed ear seat 2 is connected to two clamping parts 4 through a telescopic mechanism 3. The clamping parts 4 are used on the side of one end of the microchannel 5. Specifically, the telescopic mechanism 3 includes a double-headed cylinder. The clamping parts 4 facing each other are linked through the telescopic mechanism 3, which can flexibly adjust the clamping distance and is suitable for objects of different sizes.
[0044] Roller guides 45 are evenly distributed on the lifting portion 44 of the clamping member 4, and the arc-shaped surface 451 of the roller guides 45 extends above the lifting portion 44. Through the rolling guide structure 45 on the lifting portion 44, sliding friction is converted into rolling friction, which greatly reduces the frictional resistance with the bottom surface of the microchannel 5, prevents jamming or scratching, and the rolling of the rollers makes the clamping assembly move more smoothly, protects the workpiece surface, buffers rigid contact, avoids damage to the surface of precision workpieces, and greatly reduces the defective product yield.
[0045] The following describes the composition of the clamping component 4. The clamping component 4 includes a vertical pressing rod 41, which is slidably mounted on the fixed ear seat 2 and connected to the telescopic mechanism 3. The two vertical pressing rods 41 can move towards each other or away from each other through the telescopic mechanism 3 to lock onto both sides of the microchannel 5.
[0046] The bottom of the vertical holding rod 41 is fixed with a lifting part 44, and the lifting parts 44 in a clamping unit are arranged facing each other; the roller guide part 45 is rotatably connected to the lifting part 44, and the vertical holding rod 41 and the lifting part 44 form an L-shaped profile, and the lifting parts 44 in a clamping unit are arranged facing each other.
[0047] An elastic buffer strip 42 is provided on one side of the vertical holding rod 41, which is arranged along the length direction of the vertical holding rod 41. A V-shaped groove 43 is provided along the length direction of the elastic buffer strip 42, and the two inclined surfaces formed therein are suitable for squeezing both sides of the microchannel 5.
[0048] To improve the smoothness of scooping up the bottom surface of the lowest microchannel 5, the lifting part 44 is designed as a single three-section unit. The lifting part 44 includes a scoop head 443 adapted to abut against the bottom surface of the lowest microchannel; and the scoop head 443 has an inclined surface. The lifting part 44 also includes a support block 441, which is fixed to the bottom of the vertical holding rod 41. The support block 441 and the scoop head 443 are connected by an arc-shaped transition section 442.
[0049] Some embodiments provide a packaging device including: a conveying device and a clamping assembly as described above, the clamping assembly being disposed above the conveying device. The packaging device also includes a microchannel 5 stacking and winding device. The clamping assembly is used to place multiple wound clamping assemblies on the conveying device for transport to the next workstation, thereby improving production efficiency.
[0050] In summary, the rolling guide structure 45 on the lifting part 44 converts sliding friction into rolling friction, significantly reducing frictional resistance with the bottom surface of the microchannel 5, preventing jamming or scratching. The rolling of the rollers makes the movement of the clamping assembly smoother, protecting the workpiece surface, buffering rigid contact, avoiding damage to the surface of precision workpieces, and greatly reducing the defective product yield. By setting a telescopic mechanism 3 on a fixed lug 2, two clamping parts 4 are connected to it. The clamping parts 4 are used on the side of one end of the microchannel 5, and the clamping distance can be flexibly adjusted, which is suitable for objects of different sizes.

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