[0042] like Figure 1-4As shown, this embodiment provides a vacuum conveying line, including a frame 1, a conveying mechanism 2, an exhaust pipeline 3, a first air intake structure and a second air intake structure, the frame 1 includes a mounting plate 11, the mounting plate 11 includes an inner cavity, one side of the mounting plate 11 is provided with a plurality of through holes 111 all connected to the inner cavity, and the plurality of through holes 111 are evenly distributed on one side of the mounting plate 11; the exhaust pipeline 3 is fixedly arranged on the mounting plate 11, the exhaust pipeline 3 is connected to the inner cavity, and the exhaust pipeline 3 can be connected to an external vacuum device to evacuate the inner cavity; the conveying mechanism 2 includes a conveying drive 21, a vacuum belt and a plurality of conveying rollers 22, the plurality of conveying rollers 22 can be rotatably arranged on the mounting plate 11, both ends of the mounting plate 11 are provided with conveying rollers 22, the vacuum belt is wound around the outer sides of the plurality of conveying rollers 22, the vacuum belt is arranged corresponding to the plurality of through holes 111, and the conveying drive 21, such as a motor, can drive one of the conveying rollers 22 to rotate to drive the vacuum belt to operate for conveying operations. It should be noted that the structure and working principle of the vacuum belt are prior art and will not be described in detail here.

[0043] The first air intake structure is used to introduce gas into the inner cavity; the second air intake structure is used to introduce gas into the exhaust pipeline 3. The vacuum delivery line of this embodiment can introduce gas into the inner cavity through the first air intake structure to break the vacuum of the inner cavity, and at the same time, can also introduce gas into the exhaust pipeline 3 through the second air intake structure to break the vacuum of the exhaust pipeline 3, so as to prevent the vacuum environment in the exhaust pipeline 3 from affecting the vacuum breaking of the inner cavity. The two-way air intake at the same time can significantly increase the vacuum breaking speed, and the structure is simple.

[0044] Optionally, a plurality of first air intake structures are provided, and the plurality of first air intake structures are arranged on the mounting plate 11. By increasing the number of first air intake structures, the air intake volume and air intake speed of the inner cavity can be increased, thereby achieving the purpose of further improving the vacuum breaking speed; at the same time, arranging the plurality of first air intake structures on the mounting plate 11 is conducive to improving the uniformity of air intake, so that the pressure in the inner cavity is balanced.

[0045] It should be noted that, in the present embodiment, there is one inner cavity, and there are multiple exhaust pipelines 3, and the multiple exhaust pipelines 3 are all connected to the inner cavity, which is conducive to the inner cavity quickly reaching a vacuum environment. Since during the transportation of the battery cell pole piece, it is only necessary to break the vacuum when the battery cell pole piece is transported to the preset position, therefore, it is only necessary to break the vacuum on the inner cavity and the exhaust pipeline 3 corresponding to the preset position. In the present embodiment, among the multiple exhaust pipelines 3, at least some of the exhaust pipelines 3 are connected to multiple second air intake structures, and these part of the exhaust pipelines 3 are the exhaust pipelines 3 corresponding to the preset position. With such a configuration, the air intake volume and air intake speed of the exhaust pipeline 3 can be increased, thereby achieving the purpose of further improving the vacuum breaking speed.

[0046] Of course, in other embodiments, the inner cavity can also be set as a plurality of interconnected or unconnected cavities, and each cavity can be connected to an exhaust pipe 3. As long as the vacuum breaking operation can be performed on the cavity corresponding to the preset position through the second air intake structure and the exhaust pipe 3, no limitation is made here.

[0047] Optionally, a plurality of second air intake structures are sequentially arranged along the axial direction of the air extraction pipeline 3, which is beneficial to improving the uniformity of air intake, so that the pressure in the air extraction pipeline 3 is balanced, and thus will not affect the pressure of the inner cavity.

[0048] Optionally, the first air intake structure includes a first pipe joint 41, which is fixed to the mounting plate 11, and one end of the first pipe joint 41 is connected to the inner cavity. This arrangement facilitates the quick connection of the first pipe joint 41 to the air supply device through a pipeline, which is convenient for operation.

[0049] Optionally, the second air intake structure includes a second pipe joint 51, which is fixed to the air extraction pipeline 3, and one end of the second pipe joint 51 is connected to the air extraction pipeline 3. This arrangement facilitates the quick connection of the second pipe joint 51 to the air supply device through the pipeline, which is convenient for operation.

[0050] Optionally, the second air intake structure further includes an air intake pipe 52, one end of which is connected to the air extraction pipeline 3, and the angle between the air intake pipe 52 and the air extraction pipeline 3 is an acute angle. Such a configuration is conducive to promoting the rapid axial flow of the gas along the air extraction pipeline 3 after the gas enters the air extraction pipeline 3, thereby improving the vacuum breaking efficiency.

[0051] Exemplarily, a third pipe joint 521 is provided at the other end of the air intake pipe 52, so that the third pipe joint 521 can be quickly connected to the air supply device through a pipeline, which is convenient for operation.

[0052] In this embodiment, the exhaust pipe 3 includes an exhaust end 31, which is connected to the inner cavity; one end of the air inlet pipe 52 is connected to the exhaust pipe 3, and the other end is inclined along the axial direction of the exhaust pipe 3 away from the exhaust end 31, so that the gas in the air inlet pipe 52 can flow toward the inner cavity after entering the exhaust pipe 3, further preventing the exhaust pipe 3 from affecting the vacuum breaking of the inner cavity.

[0053] It should be noted that the first pipe joint 41 can be selected as a straight joint, an elbow or a tee joint according to the pipeline layout requirements, which is not limited here; of course, the second pipe joint 51 can also be selected as a straight joint, an elbow or a tee joint according to the pipeline layout requirements, which is not limited here; the third pipe joint 521 can also be selected as a straight joint, an elbow or a tee joint according to the pipeline layout requirements, which is not limited here.

[0054] Optionally, the conveying roller 22 includes a conveying section 221 and two mounting sections 222, and the vacuum belt is wound around the conveying section 221; the two mounting sections 222 are respectively fixedly connected to the two ends of the conveying section 221, and the two mounting sections 222 are rotatably connected to the mounting plate 11. In this way, the conveying roller 22 forms an integrated structure, and the rotating support members such as bearings can be sleeved on the mounting sections 222. When the conveying roller 22 needs to be lengthened, it is convenient to replace a larger bearing to improve the strength of the bearing and provide stable support for the lengthened conveying roller 22. Compared with the prior art, the damage and replacement frequency of the conveying roller 22 and the bearing are reduced, which is conducive to improving the working efficiency of the vacuum conveying line.

[0055] Optionally, the outer diameter of the mounting section 222 is smaller than the outer diameter of the conveying section 221. This arrangement is conducive to reducing the weight of the conveying roller 22 while ensuring that the mounting section 222 can provide stable support.

[0056] Optionally, the conveying roller 22 is made of metal aluminum, which is lighter in weight.

[0057] Furthermore, in order to improve the strength and wear resistance of the conveyor roller 22 made of metal aluminum and thereby extend the service life of the conveyor roller 22 , the outer surface of the conveyor roller 22 may be subjected to micro-arc oxidation treatment to form an oxide film on the outer surface of the conveyor roller 22 .

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
