[0045] The thermal composite pole piece includes a negative pole piece, a separator, and a positive pole piece which are stacked. The negative pole piece is formed by laser cutting a strip-shaped negative electrode material tape. During the process of laser cutting the negative pole piece, a large amount of dust is generated. In the related art, a dust removal chamber is provided near the cutting edge of the pole piece to receive the dust generated by the cutter. However, during the transmission of the pole piece, the dust will be provided to the pole piece by the conveyor belt, resulting in the dust being brought into the core package and causing a short circuit.

[0046] An embodiment of the present application provides a thermal composite pole piece cutting device, as Figures 1 to 4 shown. The thermal composite pole piece cutting device includes a cutter 6, a conveyor belt, and a pole piece cutting dust removal mechanism.

[0047] The cutter is set as a laser cutter. The laser cutter cuts the positive pole piece or the negative pole piece into a first pole piece 71 and a second pole piece 72. The first pole piece 71 is set as the pole piece material tape to be cut, and the second pole piece 72 is set as the pole piece that can be thermally compounded.

[0048] The conveyor belt includes a first pole piece conveyor belt 81 and a second pole piece conveyor belt 82. The first pole piece conveyor belt 81 is arranged to convey the pole piece strip, and the second pole piece conveyor belt 82 is arranged to convey the pole pieces to be laminated after cutting. Both the first pole piece conveyor belt 81 and the second pole piece conveyor belt 82 are connected to the fixed platform 83 and can move relative to the fixed platform 83 to convey the first pole piece 71 and the second pole piece 72. There is a gap between the first pole piece conveyor belt 81 and the second pole piece conveyor belt 82 to avoid the laser energy of the laser cutter. The fixed platform 83 includes two sets of side plates and a bottom plate connecting the two sets of side plates. There is a gap between the two sets of side plates. Each set of side plates includes two opposite side plates. The first pole piece conveyor belt 81 is fixed at the top opening of one set of side plates, and the second pole piece conveyor belt 82 is fixed at the top opening of the other set of side plates. A cavity is formed between the first pole piece conveyor belt 81 and the bottom plate, and a cavity is also formed between the second pole piece conveyor belt 82 and the bottom plate. The fixed platform 83 is provided with a fixed platform dust removal port 84, and the fixed platform dust removal port 84 is set as the gap between the two sets of side plates.

[0049] The heat lamination and cutting sheet dust removal mechanism 10 includes three dust collectors, namely a first dust collector 1, a second dust collector 2, and a third dust collector 3. Among them, the second dust collector 2, the first dust collector 1, and the third dust collector 3 are arranged in sequence along the conveying direction of the pole piece strip. The first dust collector 1 corresponds to the cutter 6 to receive the dust generated by the cutting of the cutter 6. The second dust collector 2 is located on one side of the first dust collector 1 and corresponds to the first pole piece conveyor belt 81 to receive the dust on the first pole piece conveyor belt 81. The third dust collector 3 is located on the other side of the first dust collector 1 and corresponds to the second pole piece conveyor belt 82 to receive the dust on the second pole piece conveyor belt 82.

[0050] It can be understood that since the second dust collector 2 and the third dust collector 3 are respectively arranged on both sides of the first dust collector 1, the first dust collector 1 corresponds to the cutter 6 to receive most of the dust generated by the cutting of the cutter 6, the second dust collector 2 corresponds to the first pole piece conveyor belt 81 to receive the dust on the first pole piece conveyor belt 81, and the third dust collector 3 corresponds to the second pole piece conveyor belt 82 to receive the dust on the second pole piece conveyor belt 82, thus fully cleaning the dust on the pole piece conveyor belt.

[0051] In some embodiments, continue to refer to Figures 1 to 4, the first dust collector 1 includes a first dust removal chamber 11 and a first dust suction pipe 14 connected to the first dust removal chamber 11. The first dust removal chamber 11 has a first dust removal port 12, the first dust suction pipe 14 has a first dust suction port 13, and the first dust removal port 12 communicates with the first dust suction port 13. The first dust removal chamber 11 includes a plurality of opposite side walls, and the first dust removal port 12 is provided on one of the side walls. The top and bottom of the first dust removal chamber 11 are open. The first dust suction pipe 14 is connected to a negative pressure so that the dust inside the first dust removal chamber 11 enters the first dust suction port 13 under the action of the negative pressure.

[0052] A blowing member 15 is further provided on the first dust removal chamber 11. The blowing member 15 is disposed opposite to the first dust removal port 12, thereby facilitating blowing the dust in the first dust removal chamber 11 towards the first dust removal port 12.

[0053] The second dust collector 2 includes a second dust removal chamber 21 and a second dust suction pipe 24 connected to the second dust removal chamber 21. The second dust removal chamber 21 has a second dust removal port 22, and the second dust suction pipe 24 is further provided with a second dust suction port 23. The second dust suction port 23 communicates with the second dust removal port 22. The second dust removal chamber 21 includes a plurality of opposite side walls, and the second dust removal port 22 is provided on one of the side walls. The top and bottom of the second dust removal chamber 21 are open. The second dust suction pipe 24 is connected to a negative pressure so that the dust inside the second dust removal chamber 21 enters the second dust suction pipe 24 under the action of the negative pressure.

[0054] The third dust collector 3 includes a third dust removal chamber 31 and a third dust suction pipe 34 connected to the third dust removal chamber 31. The third dust removal chamber 31 has a third dust removal port 32, and the third dust suction pipe 34 is further provided with a third dust suction port 33. The third dust suction port 33 communicates with the third dust removal port 32. The third dust removal chamber 31 includes a plurality of opposite side walls, and the third dust removal port 32 is provided on one of the side walls. The top and bottom of the third dust removal chamber 31 are open. The third dust suction pipe 34 is connected to a negative pressure so that the dust inside the third dust removal chamber 31 enters the third dust suction pipe 34 under the action of the negative pressure.

[0055] In some embodiments, the first dust collector 1, the second dust collector 2, and the third dust collector 3 are independent of each other, so that the three dust collectors can independently adjust the dust adsorption process.

[0056] In a specific embodiment, the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31 are integrally formed. The first dust removal chamber 11 is located between the second dust removal chamber 21 and the third dust removal chamber 31. The first dust removal chamber 11 and the second dust removal chamber 21 are separated by one side wall, and the first dust removal chamber 11 and the third dust removal chamber 31 are separated by another side wall.

[0057] The first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31 all have opposite first side walls and second side walls. The first dust removal port 12 is located on the first side wall, and correspondingly, the first dust suction pipe 14 is connected to the first side wall. The second dust removal port 22 of the second dust removal chamber 21 is located on the second side wall, and correspondingly, the second dust suction pipe 24 is connected to the second side wall. The third dust removal port 32 of the third dust removal chamber 31 is located on the second side wall, and correspondingly, the third dust suction pipe 34 is connected to the second side wall. By connecting the second dust suction pipe 24 or the third dust suction pipe 34 to the opposite side wall, it is beneficial for the first dust suction pipe 14 to expand the cross-sectional area where the first dust suction port 13 is located.

[0058] In some embodiments, the cross-sectional area of the first dust suction port 13 is larger than the cross-sectional area of the third dust suction port 33. By setting the cross-sectional area of the first dust suction port 13 to be larger than the cross-sectional area of the second dust suction port 23 or the third dust suction port 33, the first dust suction port 13 has a greater dust adsorption capacity.

[0059] Among them, the first dust suction port 13 corresponds to the cutter 6. In addition to communicating with the first dust removal port 12 of the first dust removal chamber 11, the first dust suction port 13 also communicates with the fixed table dust removal port 84, so that the first dust suction port 13 can absorb the dust in the upper space at the cutting position of the pole piece, and the first dust suction port 13 can also absorb the dust in the lower space at the cutting position of the pole piece. The upper space at the cutting position of the pole piece is set as the first dust removal chamber 11 of the first dust collector 1, and the lower space at the cutting position of the pole piece is set as the lower cavity of the first pole piece conveyor belt 81 and the second pole piece conveyor belt 82. The second dust suction port 23 corresponds to the first pole piece conveyor belt 81, and the second dust suction port 23 communicates with the second dust removal port 22 of the second dust removal chamber 21. The third dust suction port 33 corresponds to the second pole piece conveyor belt 82, and the third dust suction port 33 communicates with the third dust removal port 32 of the third dust removal chamber 31. Therefore, the dust in the upper space of the first pole piece can be absorbed by the second dust collector 2, the dust in the lower space of the first pole piece can be absorbed by the first dust collector 1, the dust in the upper space of the second pole piece can be absorbed by the third dust collector 3, and the dust in the lower space of the second pole piece can be absorbed by the first dust collector 1, so as to fully clean the dust generated during the cutting of the pole piece.

[0060] In some embodiments, the width of the first dust removal chamber 11 or the second dust removal chamber 21 or the third dust removal chamber 31 is set to be greater than the width of the pole piece. The width direction of the pole piece is as Figure 1The difference between the width of the y-direction shown, such as the width of the first dust removal chamber 11, the second dust removal chamber 21, or the third dust removal chamber 31 and the width of the pole piece, is set to be greater than 40 mm. After the axis in the length direction of the pole piece coincides with the axis in the length direction of the first dust removal chamber 11, the second dust removal chamber 21, or the third dust removal chamber 31, there is a sufficient interval between both sides of the pole piece and the first dust removal chamber 11, the second dust removal chamber 21, or the third dust removal chamber 31, so as to prevent the edge of the pole piece from contacting the edge of the first dust removal chamber 11, the second dust removal chamber 21, or the third dust removal chamber 31.

[0061] In some embodiments, the first dust suction port 13 is set to be rectangular, the length of the first dust suction port 13 is 60 mm, and the length direction of the first dust suction port 13 is as Figure 1 shown in the x-direction. The height of the first dust suction port 13 is 100 mm. The length of the second dust suction port 23 is 60 mm, and the height of the second dust suction port 23 is 50 mm. The length of the third dust suction port 33 is 60 mm, and the height of the third dust suction port 33 is 50 mm. The height of the first dust suction port 13 is set to be greater than the height of the second dust suction port 23, and the height of the first dust suction port 13 is set to be greater than the height of the third dust suction port 33, so that the first dust suction port 13 can adsorb most of the dust.

[0062] In some embodiments, the hot composite cutting sheet dust removal mechanism 10 further includes a dust removal cover 4, and the dust removal cover 4 is arranged at the top openings of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31, so as to effectively prevent dust from diffusing into the equipment workshop through the top openings of the first dust collector 1, the second dust collector 2, and the third dust collector 3 and causing the dust particle size in the equipment workshop to exceed the standard. A cutting opening 41 is also provided on the dust removal cover 4, and the laser generated by the laser cutter passes through the cutting opening 41 to cut the pole piece.

[0063] In some embodiments, the width of the cutting opening 41 is set to be greater than the width of the first pole piece 71 or the second pole piece 72, so that the laser generated by the laser cutter can fully cut the pole piece. For example, the difference between the width of the cutting opening 41 and the width of the first pole piece 71 or the second pole piece 72 is set to be greater than 40 mm. Among them, the length of the cutting opening 41 is set to be 0.1 mm to 12 mm. The width direction of the cutting opening 41 is set to the width direction of the pole piece, and the length direction of the cutting opening 41 is set to the length direction of the pole piece. It can be understood that when the length of the cutting opening 41 is set to be less than 0.1 mm, the laser slit defined by the cutting opening 41 is too narrow, which is not conducive to the laser generated by the laser cutter to cut the pole piece through the cutting opening 41. When the length of the cutting opening 41 is set to be greater than 12 mm, the dust inside the first dust removal chamber 11 will enter the equipment workshop through the cutting opening 41 and contaminate the pole piece. In a specific implementation, the length of the cutting opening 41 can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, and any value between the above two values or any range between any two of the above values.

[0064] The bottoms of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31 are all provided with openings, so as to facilitate the first pole piece conveyor belt 81 to drive the first pole piece 71 to run at the bottoms of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31, and the second pole piece conveyor belt 82 to drive the second pole piece 72 to run at the bottoms of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31.

[0065] In some embodiments, the thermal composite cutting piece dust removal mechanism further includes a dust cover driving mechanism 5, and the dust cover driving mechanism 5 is connected to the dust cover 4 to drive the dust cover 4 to move so as to open the first dust removal chamber 11 and / or the second dust removal chamber 21 and / or the third dust removal chamber 31.

[0066] By setting the dust cover driving mechanism 5 to open the top openings of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31, on the one hand, the cutting effect of the pole piece can be directly observed. On the other hand, during the cutting process of the pole piece, when a running failure occurs in the pole piece conveyor belt or the pole piece, such as material blockage or belt breakage, by opening the top openings of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31, it is convenient for maintenance.

[0067] In some embodiments, the dust cover driving mechanism 5 includes a connecting arm 51 and a lifting assembly 52 that are connected to each other. The connecting arm 51 is connected to the dust cover 4, and the lifting assembly 52 is configured to drive the dust cover 4 to move along the height direction of the thermal composite cutting piece dust removal mechanism to open the top openings of the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31.

[0068] In some embodiments, such as Figure 1 andFigure 5 As shown, the lifting assembly 52 includes a driving member and a driving switch. The driving member can be a motor or a lifting cylinder, and the driving switch can be a button. By controlling the driving switch, the lifting assembly 52 is controlled to perform the lifting or lowering operation, thereby driving the dust removal cover 4 to rise to open the first dust removal chamber 11, the second dust removal chamber 21, and the third dust removal chamber 31, or driving the dust removal cover 4 to lower to close the first dust removal chamber 11, the second dust removal chamber 21, or the third dust removal chamber 31.

[0069] In some embodiments, the dust removal cover driving mechanism 5 further includes a limiting assembly 53. The limiting assembly 53 is configured to limit the lifting stroke of the dust removal cover 4 to prevent the dust removal cover 4 from interfering with the cutter 6 during the rising process, thereby damaging the cutter 6. The limiting assembly 53 includes a limiter 531 and a limit inductor 532. The height difference between the limit inductor 532 and the dust removal cover 4 is less than the height difference between the cutter 6 and the dust removal cover 4, so that the maximum rising height of the dust removal cover 4 is not higher than the limit inductor 532. The limit inductor 532 is linked with the limiter 531. The limit inductor 532 controls the limiter 531 to limit the lifting assembly 52 from rising further by identifying the lifting position of the dust removal cover 4.

[0070] An embodiment of the present application further provides a thermal compounding device. The thermal compounding device includes the above-mentioned thermal compounding and cutting device and the pole piece thermal compounding device. The thermal compounding and cutting device is configured to cut the thermally compounded pole piece, and the thermal compounding device is configured to process and form a thermally compounded pole piece assembly.

Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, based on the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
