Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical manufacturing, in particular to a dust removal device and a slicing device. BACKGROUND

[0002] In mechanical manufacturing, controlling the dust generated in the slicing process is a key factor affecting the formation of batteries. Once the metal dust generated during slicing is left, it will accelerate the wear of mechanical parts, and even cause a short circuit. Generally, negative pressure dust removal is performed by using a traditional contact type dust removal method such as a dust removal mask. However, this contact type dust removal method will form dead angles due to disordered air flow organization, has a high dust escape rate, and the dust removal mask is easy to be blocked during high-speed continuous cutting.

[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 the embodiment of the present application, the first dust removal component 10 and the second dust removal component 20 can be located above and below the slicing gap 30 of the slicing device 3 respectively, the first dust removal component 10 mainly plays a role of dust removal on the upper surface of the sheet, and the second dust removal component 20 mainly plays a 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 reciprocating movement perpendicular to the conveying direction of the sheet, and the first dust removal component 10 can be periodically moved towards the sheet, so that the slicing channel 11 is periodically aligned with the slicing gap 30 of the slicing device 3, when the slicing channel 11 is aligned with the slicing gap 30 of the slicing device 3, the first dust removal component 10 can press the sheet to prevent dust from spreading, and the laser emitted by the laser mechanism of the slicing device 3 can enter and be emitted onto the slicing gap 30 to cut the sheet conveyed to the slicing gap 30, at the same time, the dust generated above the slicing gap 30 can enter the dust removal channel 12 through the slicing channel 11, and the dust can be directly extracted, realizing the synergy of dust removal on the upper surface of the sheet and the slicing frequency.

[0031] The second dust removal component 20 can be a rotating structure, and the dust suction port 21 of the second dust removal component 20 is periodically aligned with the slicing gap 30 through rotation. When the sheet is sliced, the dust suction port 21 can suck away the dust generated below the slicing gap 30 when the dust suction port 21 is aligned with the slicing gap 30 through rotation. Moreover, the rotation period of the second dust removal component 20 matches the cutting frequency, realizing the synergy of dust removal on the lower surface of the sheet and the slicing frequency. After the slicing is completed, the second dust removal component 20 rotates, and the dust suction port 21 is misaligned with the slicing gap 30 through rotation, so that the dust can be enclosed in the second dust removal component 20, avoiding the spread and escape of the dust, and achieving better dust removal effect.

[0032] In the embodiment of the present application, the slicing channel 11 of the first dust removal component 10 integrates the dust removal function without occupying additional space; the rotating design of the second dust removal component 20 can cover a larger adsorption range, and the two components realize a compact and efficient dust removal layout in cooperation. The movement period of the first dust removal component 10 and the second dust removal component 20 matches the sheet cutting frequency, ensuring that the dust removal action is synchronized with the cutting rhythm. For example, if the cutting frequency is 1 time per second, the movement period of the dust removal component can also be adjusted to 1 second / time, realizing the same frequency of cutting and dust removal.

[0033] Therefore, the dust removal device of the embodiment of the present application can realize the instant removal and secondary capture of cutting dust through the synergy of the first dust removal mechanism 1 and the second dust removal mechanism 2, combined with the precise matching of the movement period and the slicing frequency, effectively avoiding the secondary pollution of the dust, and reducing the influence of the dust on the cutting precision and the quality of the sheet.

[0035] In the embodiment, the dust removal channel 12 comprises the blowing channel 120 and the suction channel 121, the blowing channel 120 is arranged upstream of the slicing channel 11 along the material movement direction, and is used for spraying a positive pressure airflow along the material movement direction to blow the dust generated by cutting to the suction channel 121, so that the dust can be prevented from spreading to the slicing device 3 arranged upstream of the cutting area. The suction channel 121 is arranged downstream, and can be connected with a negative pressure system, the negative pressure generated by the suction channel 121 and the positive pressure generated by the blowing channel 120 form a convection, so that the suction force on the dust is increased, and the dust removal efficiency is improved through airflow directional guidance, and the dust spreading is avoided.

[0037] When the material is cut by the laser, a large amount of dust will be splashed, and the dust removal airflow generated by the blowing channel 120 and the suction channel 121 can not take away the dust above the cutting area. By additionally arranging the air inlet channel 13 above the blowing channel 120, air is introduced into the air inlet channel 13, the suction channel 121 and the air inlet channel 13 form a convection, and the dust above the cutting area is sucked away.

[0038] As a preferred embodiment, referring to Figure 1 and Figure 3 The first dust removal mechanism 1 further comprises a plurality of blowing connectors 14 arranged on the first dust removal component 10, the blowing connectors 14 are communicated with the blowing channel 120, and are used for introducing a positive pressure airflow into the blowing channel 120.

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

[0043] As an optional embodiment, referring to Figure 3 The second dust removal component 20 comprises an inner roller 200 and an outer roller 201, the inner roller 200 being provided with a dust inlet 22, the dust inlet 22 being oppositely arranged with the slicing gap 30; the outer roller 201 being rotatably sleeved outside the inner roller 200, and the outer roller 201 being provided with at least one dust suction port 21; and through the rotation of the outer roller 201, the dust suction port 21 is periodically communicated with the at least one dust inlet 22 and the slicing gap 30, so that the dust enters the inner roller 200.

When slicing, the outer roller 201 can be rotated to align the dust suction port 21 and the dust suction port 21 with the slicing gap 30, so that the dust enters the inner roller 200 through the dust inlet 22 via the dust suction port 21. After slicing, the outer roller 201 can continue to rotate to misalign the dust suction port 21 and the dust inlet 22, so that the dust can be enclosed in the inner roller 200, avoiding the spread of the dust and achieving better dust removal effect. Through the periodic rotation and suction design, the dust suction range can be expanded, and the slicing frequency can be matched. Moreover, the inner and outer rollers cooperate to realize dynamic dust removal, avoiding dust accumulation.

[0045] In addition, in the embodiment of the present application, the number of dust suction ports 21 can be set according to the slicing frequency. For example, in the embodiment of the present application, two dust suction ports 21 can be uniformly distributed in the radial direction of 180° of the outer roller 201, and the outer roller 201 rotates one revolution to perform cutting and dust removal once.

One end of the inner roller 200 is provided with an air outlet 203 for providing negative pressure to suck away the dust in the inner roller 200.

[0047] In the embodiment of the present application, the blowing channel 202 is located between the outer roller 201 and the inner roller 200 to pass the positive pressure airflow into the dust inlet 22 to assist the dust into the inner roller 200. The air outlet 203 can be connected with a negative pressure system to suck away the dust in the inner roller 200 to form a “blowing + suction” cycle. Through the synergistic effect of positive and negative pressure, the dust collection efficiency is improved, and the dust is prevented from depositing in the inner roller 200 to realize periodic dust removal.

The protective cover 23 can adsorb residual dust and capture particles escaping due to air flow disturbance or sheet movement. Moreover, the residual dust can be concentrated and guided to the dust suction port 21 in the dust removal space 24, thereby preventing dust overflow and improving the dust removal effect of the second dust removal mechanism 2.

[0054] In order to further understand the embodiment of the present application, the working principle of the dust removal device of the present application is specifically described as follows: Referring to Figure 3 , Figure 5 and Figure 6 ( Figure 6 The red arrow represents the air flow path, and the black arrow represents the dust movement path), when the sheet moves to the cutting area, the first dust removal component 10 moves close to the sheet perpendicular to the sheet conveying direction to press the sheet, blows air into the air blowing channel 120, and air is sucked into the air suction channel 121, to form a dust removal flow field on the upper surface of the sheet to carry away the dust on the upper surface of the sheet; at the same time, the outer roller 201 rotates to align the dust suction port 21 with the slicing gap 30, and the dust suction port 21 coincides with the dust inlet port 22. By blowing air into the air blowing channel 202, the positive pressure air flow enters the inner roller 200 through the dust inlet port 22, and the air suction port 203 of the inner roller 200 sucks air, so that the dust is sucked into the inner roller 200 by the positive and negative pressure flow fields of the inner roller 200 and the outer roller 201, to complete the dust removal of the lower surface of the sheet. After cutting, the first dust removal component 10 moves away from the sheet perpendicular to the sheet conveying direction to release the sheet, at the same time, the outer roller 201 rotates to misalign the dust suction port 21 with the slicing gap 30, the dust inlet port 22 is closed, and the dust is sucked away through the air suction port 203, to complete the dust removal of the lower surface of the sheet, and avoid dust overflow.

[0056] Referring to Figure 7 , the present application also provides a slicing equipment, which comprises a slicing device 3 and the foregoing dust removal device. The slicing device 3 comprises a conveying mechanism 31 and a laser mechanism 32.

The laser mechanism 32 is aligned with the slicing gap 30 and periodically emits laser to the slicing gap 30 to cut the sheet. The first dust removal mechanism 1 and the second dust removal mechanism 2 are arranged on the two sides of the supporting plate 310 relative to the slicing gap 30.

[0057] In the embodiment of the present application, the slicing device comprises a slicing apparatus 3 and a dust removal apparatus. The slicing apparatus 3 comprises a conveying mechanism 31 and a laser mechanism 32. The conveying mechanism 31 can be driven by a traction device to periodically convey the sheet, and the laser mechanism 32 periodically emits laser to cut the sheet. The dust removal apparatus cooperates with the laser mechanism 32 to remove dust at 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, so as to ensure that the dust removal action is synchronized with the cutting rhythm. For example, if the cutting frequency is 1 time per second, the movement period of the dust removal component can also be adjusted to 1 second / time, so as to realize the same frequency of cutting and dust removal.

[0058] Therefore, the slicing device of the embodiment of the present application can match the dust removal period with the slicing frequency through the cooperation of the first dust removal mechanism 1 and the second dust removal mechanism 2 with the laser mechanism 32, so as to realize the instant removal and secondary capture of cutting dust, effectively avoid the secondary pollution of dust, and reduce the influence of dust on the cutting precision and the sheet quality.
