Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing technology, and in particular to dust removal devices and slicing equipment. Background Technology

[0002] In mechanical manufacturing, controlling the dust generated during the slicing process is a key factor affecting battery molding. Residual metallic dust generated during slicing can accelerate the wear of mechanical parts and even cause short circuits. Traditional contact dust removal methods, such as using a dust collector mask for negative pressure dust removal, are commonly used. However, this contact dust removal method can create dead zones due to chaotic airflow, resulting in a high dust escape rate. Furthermore, the dust collector mask is prone to clogging during high-speed continuous cutting.

[0003] In related technologies, non-contact dust removal methods are employed, such as setting up exhaust structures near the upper and lower surfaces of the sheet. The negative pressure generated by the fan directly captures dust generated on the upper and lower surfaces of the sheet, preventing dust diffusion. However, this non-contact dust removal method is difficult to control in terms of airflow balance, and the mismatch between the frequency of dust removal and cutting operations can cause secondary dust pollution. Furthermore, it can easily cause sheet vibration, leading to laser defocusing and affecting cutting accuracy. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] Traditional contact dust removal methods, such as using dust collection masks for negative pressure dust removal, are commonly used. However, this method can create dead zones due to chaotic airflow, resulting in high dust escape rates. Furthermore, the dust collection mask is prone to clogging during high-speed continuous cutting. Related technologies employ non-contact dust removal methods, such as installing exhaust structures near the upper and lower surfaces of the sheet. The negative pressure generated by the fan directly captures dust generated on these surfaces, preventing dust diffusion. However, this non-contact dust removal method faces difficulties in balancing the airflow, and the mismatch between dust removal and cutting frequencies can cause secondary dust pollution. It can also easily induce sheet vibration, leading to laser defocusing and affecting cutting accuracy.

[0026] To address the aforementioned issues, this application provides a dust removal device that utilizes the combined dust removal functions of a first dust removal mechanism and a second dust removal mechanism, with the dust removal cycle matching the slicing frequency, thereby avoiding secondary dust contamination and reducing the impact on slicing accuracy.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] See Figure 1 and Figure 3 This application provides a dust removal device, including a first dust removal mechanism 1 and a second dust removal mechanism 2. The first dust removal mechanism 1 includes a first dust removal component 10 that can move relative to the sheet. The first dust removal component 10 has a through slicing channel 11 perpendicular to the sheet transport direction, and a dust removal channel 12 communicating with the slicing channel 11 is formed inside the first dust removal component 10. When the first dust removal component 10 moves toward the sheet, the slicing channel 11 periodically aligns with the slicing gap 30 of the slicing device 3. The second dust removal mechanism 2 includes a rotatable second dust removal component 20, which is disposed opposite to the first dust removal component 10 and has a suction port 21. When the second dust removal component 20 rotates, the suction port 21 periodically aligns with the slicing gap 30. The movement period of the first dust removal component 10 and the second dust removal component 20 matches the sheet cutting frequency.

[0029] In this embodiment of the application, the first dust removal component 10 and the second dust removal component 20 are located above and below the slicing gap 30 of the slicing device 3, respectively. The first dust removal component 10 mainly plays the role of dust removal on the upper surface of the sheet, and the second dust removal component 20 mainly plays the role of dust removal on the lower surface of the sheet.

[0030] The movement of the first dust removal component 10 relative to the sheet can be a reciprocating motion perpendicular to the sheet transport direction, and the first dust removal component 10 can periodically move toward the sheet, so that the slicing channel 11 periodically aligns with the slicing slit 30 of the slicing device 3. When the slicing channel 11 aligns with the slicing slit 30 of the slicing device 3, the first dust removal component 10 can press down on the sheet to prevent dust from spreading; and allow the laser emitted by the laser mechanism of the slicing device 3 to enter and strike the slicing slit 30 to cut the sheet transported to the slicing slit 30. At the same time, the dust generated above the slicing slit 30 can enter the dust removal channel 12 through the slicing channel 11, and the dust can be directly extracted, realizing the synergistic effect of dust removal on the upper surface of the sheet and slicing frequency.

[0031] The second dust removal component 20 can be a rotating structure, and its suction port 21 periodically aligns with the slicing slit 30 as it rotates. During slicing, when the suction port 21 rotates and aligns with the slicing slit 30, it can suck up the dust generated below the slicing slit 30. Furthermore, the rotation cycle of the second dust removal component 20 matches the cutting frequency, achieving a synergistic effect between dust removal on the lower surface of the sheet and the slicing frequency. After slicing, the second dust removal component 20 rotates, and the suction port 21, through rotation, misaligns with the slicing slit 30, allowing the dust to be sealed within the second dust removal component 20, preventing dust diffusion and escape, and achieving a better dust removal effect.

[0032] In this embodiment, the slicing channel 11 of the first dust removal component 10 integrates dust removal functionality without requiring additional space; the rotating design of the second dust removal component 20 can cover a larger adsorption range, and the two work together to achieve a compact and efficient dust removal layout. The movement cycles of the first dust removal component 10 and the second dust removal component 20 are matched with the sheet cutting frequency to ensure that the dust removal action is synchronized with the cutting rhythm. For example, if the cutting frequency is once per second, the movement cycle of the dust removal component can also be adjusted to once per second to achieve synchronous cutting and dust removal.

[0033] Therefore, the dust removal device in this embodiment can achieve immediate removal and secondary collection of cutting dust by the synergistic effect of the first dust removal mechanism 1 and the second dust removal mechanism 2, combined with the precise matching of the motion cycle and the slicing frequency. This effectively avoids secondary dust pollution and reduces the impact of dust on cutting accuracy and sheet quality.

[0034] As an optional embodiment, see Figure 3The dust removal channel 12 includes a first air blowing channel 120 and an air suction channel 121 arranged relative to the slicing channel 11. The first air blowing channel 120 is located upstream of the air suction channel 121 along the sheet movement direction, and both the first air blowing channel 120 and the air suction channel 121 are connected to the slicing channel 11.

[0035] In this embodiment, the dust removal channel 12 includes a first blowing channel 120 and a suction channel 121. The first blowing channel 120 is located upstream of the slicing channel 11 along the sheet movement direction and is used to spray positive pressure airflow along the sheet movement direction to blow the dust generated during cutting towards the suction channel 121, thus preventing the dust from spreading to the slicing device 3 located upstream of the cutting area. The suction channel 121 is located downstream and can be connected to a negative pressure system. The negative pressure generated by the suction channel 121 and the positive pressure generated by the first blowing channel 120 form convection, increasing the suction force on the dust. Moreover, the directional guidance of the airflow improves the dust removal efficiency and prevents dust diffusion.

[0036] As a preferred embodiment, see Figure 3 The first dust removal component 10 is also provided with an air intake channel 13. The air intake channel 13 and the first blowing channel 120 are located on the same side of the slicing channel 11, and the air intake channel 13 is located above the first blowing channel 120 and is connected to both the slicing channel 11 and the suction channel 121.

[0037] When laser cutting sheet material, a high amount of dust will be splashed. The dust removal airflow generated by the first air blowing channel 120 and the air suction channel 121 may not be able to remove the dust located above the cutting area. By adding an air intake channel 13 located above the first air blowing channel 120, air is introduced into the air intake channel 13, and the air suction channel 121 is connected to the air intake channel 13 to form convection, which can suck away the dust located above the cutting area.

[0038] As a preferred embodiment, see Figure 1 and Figure 3 The first dust removal mechanism 1 also includes a plurality of air blowing connectors 14 disposed on the first dust removal component 10. The air blowing connectors 14 are connected to the first air blowing channel 120 and are used to introduce positive pressure airflow into the first air blowing channel 120.

[0039] In this embodiment, the air blowing connector 14 is connected to an external air source to introduce high-pressure airflow into the first air blowing channel 120, which can enhance the blowing force. Moreover, the air blowing connector 14 provides adjustable airflow to adapt to different cutting conditions.

[0040] As a preferred embodiment, see Figures 1 to 3The first dust removal mechanism 1 also includes at least one protective component 15, which includes a suction pipe 150 and a dust removal hood 151 fitted over the suction pipe 150. The suction pipe 150 is connected to the air intake channel 121, and the dust removal hood 151 is sealed to the air intake channel 121.

[0041] In this embodiment, the protective component 15 includes a suction pipe 150 and a dust cover 151. The suction pipe 150 is connected to the air intake channel 121, and the dust cover 151 seals the outlet of the air intake channel 121 to prevent dust from overflowing.

[0042] It should be noted that in the embodiments of this application, the first dust removal component 10 can be a pressure plate structure, which drives the pressure plate to move up and down through a cam mechanism. For example, the motor drives the cam to rotate, and through bearings, guide rails and other mechanisms, the circular motion is converted into a periodic reciprocating linear motion. The pressure plate is connected at the execution end to realize the periodic up and down movement of the pressure plate.

[0043] As an optional embodiment, see Figure 3 The second dust removal component 20 includes an inner roller 200 and an outer roller 201. The inner roller 200 has a dust inlet 22, which is disposed opposite to the slicing gap 30. The outer roller 201 is rotatably sleeved on the inner roller 200, and at least one dust suction port 21 is provided on the outer roller 201. By rotating the outer roller 201, the dust suction port 21 can periodically communicate with at least one dust inlet 22 and the slicing gap 30, so that dust can enter the inner roller 200.

[0044] In this embodiment, the inner roller 200 can be fixed, and its dust inlet 22 can always be aligned with the slicing gap 30. By rotating the outer roller 201, the suction port 21 periodically connects with at least one dust inlet 22 and the slicing gap 30, allowing dust to enter the inner roller 200 sequentially from the slicing gap 30 via the dust inlet 22 and the suction port 21. During slicing, the outer roller 201 can rotate until both the suction port 21 and the suction port 22 are aligned with the slicing gap 30, allowing dust to enter the inner roller 200 via the dust inlet 22 through the suction port 21. After slicing, the outer roller 201 can continue to rotate until the suction port 21 is misaligned with the dust inlet 22, allowing the dust to be contained within the inner roller 200, preventing dust diffusion and escape, and achieving better dust removal. The periodic rotation and suction design expands the suction range and matches the slicing frequency. Furthermore, the cooperation between the inner and outer rollers achieves dynamic dust removal, preventing dust accumulation.

[0045] In addition, the number of dust suction ports 21 in this embodiment can be set according to the slicing frequency. For example, in this embodiment, two dust suction ports 21 can be evenly distributed in the radial 180° direction of the outer roller 201, and the outer roller 201 can rotate half a circle to perform one cutting and dust removal.

[0046] As a preferred embodiment, see Figures 3 to 5 ( Figure 5 (The red arrows indicate the airflow path, and the blue arrows indicate the dust movement path.) A second air blowing channel 202 is formed between the outer roller 201 and the inner roller 200 to allow positive pressure airflow to enter. The second air blowing channel 202 is connected to the dust inlet 22 to allow positive pressure airflow into the inner roller 200. One end of the inner roller 200 is provided with an air extraction port 203, which is used to provide negative pressure to remove dust from the inner roller 200.

[0047] In this embodiment, the second air blowing channel 202 is located between the outer roller 201 and the inner roller 200, and introduces positive pressure airflow into the dust inlet 22 to assist dust in entering the inner roller 200. The exhaust port 203 can be connected to a negative pressure system to remove dust from the inner roller 200, forming a "blowing in + extraction" cycle. Through the synergistic effect of positive and negative pressure, the dust collection efficiency is improved, and dust deposition in the inner roller 200 is prevented, achieving periodic dust removal.

[0048] As a preferred embodiment, see Figure 4 and Figure 5 The second dust removal component 20 also includes an air blowing pipe 204. One end of the air blowing pipe 204 is connected to the end of the inner roller 200 away from the air extraction port 203, and a first air blowing port 205 is provided on the air blowing pipe 204. The first air blowing port 205 is connected to the second air blowing channel 202.

[0049] In this embodiment, the air blowing pipe 204 is connected to the inner roller 200, and the first air blowing port 205 is aligned with the second air blowing channel 202, which can enhance the airflow conveying efficiency. By optimizing the airflow path, pressure loss can be reduced and the purging effect can be improved.

[0050] As a preferred embodiment, see Figure 4 and Figure 5 The second dust removal component 20 also includes an air blowing sleeve 206, which is connected to the outer roller 201, and a second air blowing port 207 is provided on the air blowing sleeve 206, which is connected to the second air blowing channel 202.

[0051] In this embodiment, the air-blowing sleeve 206 is fixed to the outer roller 201, and the second air-blowing port 207 is connected to the second air-blowing channel 202 to provide auxiliary airflow. This can enhance the airflow stability when the outer roller 201 rotates and prevent dust adhesion.

[0052] As an optional embodiment, see Figure 3 The second dust removal mechanism 2 also includes a protective cover 23 covering the second dust removal component 20. The opening of the protective cover 23 faces the slicing gap 30, and a dust removal space 24 for dust to enter is formed between the protective cover 23 and the second dust removal component 20.

[0053] In this embodiment, the protective cover 23 covers the second dust removal component 20, and the opening of the protective cover 23 is aligned with the slit 30, forming a sealed dust removal space 24. The protective cover 23 can adsorb residual dust and capture particles that escape due to airflow disturbance or sheet movement. Moreover, residual dust can be concentrated and guided to the suction port 21 within the dust removal space 24, thereby preventing dust overflow and improving the dust removal effect of the second dust removal mechanism 2.

[0054] To further understand the embodiments of this application, the working principle of the dust removal device of this application is described in detail below: See Figure 3 , Figure 5 and Figure 6 ( Figure 6 (The red arrows indicate the airflow path, and the black arrows indicate the dust movement path.) When the sheet moves to the cutting area, the first dust removal component 10 moves towards the sheet perpendicular to the sheet transport direction until it presses down on the sheet. By blowing air into the first air blowing channel 120 and introducing air into the air intake channel 13, and cooperating with the suction channel 121 to draw air in, a dust removal flow field is formed on the upper surface of the sheet, carrying away the dust on the upper surface of the sheet. At the same time, the outer roller 201 rotates until the dust suction port 21 is aligned with the cutting gap 30, and the dust suction port 21 coincides with the dust inlet 22. By blowing air into the second air blowing channel 202, the positive pressure airflow enters the inner roller 200 through the dust inlet 22. The inner roller 200's air extraction port 203 draws in air, causing the dust to be drawn into the inner roller 200 by the positive and negative pressure flow fields of the inner roller 200 and the outer roller 201, completing the dust removal of the lower surface of the sheet. After cutting, the first dust removal component 10 moves away from the sheet along a direction perpendicular to the sheet conveying direction until the sheet is released. At the same time, the outer roller 201 rotates until the dust suction port 21 is offset from the cutting gap 30, the dust inlet 22 is closed, and the dust is drawn away through the air extraction port 203, completing the dust removal of the lower surface of the electrode sheet and preventing dust from overflowing.

[0055] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a slicing device and corresponding embodiments.

[0056] See Figure 7 This application embodiment also provides a slicing device, including a slicing apparatus 3 and the aforementioned dust removal device. The slicing apparatus 3 includes a conveying mechanism 31 and a laser mechanism 32. The conveying mechanism 31 includes a pallet 310. A slicing slit 30 is provided on the pallet 310 along a direction perpendicular to the sheet conveying direction. The laser mechanism 32 is aligned with the slicing slit 30 and periodically emits a laser into the slicing slit 30 to cut the sheet. The first dust removal mechanism 1 and the second dust removal mechanism 2 are respectively disposed on both sides of the pallet 310 opposite to the slicing slit 30.

[0057] In this embodiment, the slicing equipment includes a slicing device 3 and a dust removal device. The slicing device 3 includes a conveying mechanism 31 and a laser mechanism 32. The conveying mechanism 31 can be driven by a traction device to periodically feed the sheet. The laser mechanism 32 periodically emits laser light to cut the sheet. The dust removal device works in conjunction with the laser mechanism 32 to remove dust at the slicing gap 30. The movement cycle of the first dust removal component 10 and the second dust removal component 20 matches the sheet cutting frequency to ensure that the dust removal action is synchronized with the cutting rhythm. For example, if the cutting frequency is once per second, the movement cycle of the dust removal component can also be adjusted to once per second to achieve synchronous cutting and dust removal.

[0058] Therefore, the slicing device of this application embodiment can achieve the matching of the dust removal cycle with the slicing frequency through the synergistic effect of the first dust removal mechanism 1, the second dust removal mechanism 2 and the laser mechanism 32, thereby realizing the immediate removal and secondary collection of cutting dust, effectively avoiding secondary dust pollution, and reducing the impact of dust on cutting accuracy and sheet quality.
