The negative pressure device in the above embodiment may be a device capable of generating negative pressure, such as an exhaust fan.
To further illustrate the concepts and details of the present application, the following description is presented in terms of specific embodiments:
referring to fig. 1-3, the utility model discloses a pole piece cutting device, including belt subassembly 20, just to belt subassembly 20's laser cutting subassembly 14, be located the useless subassembly 40 of collection and supporting clearance mechanism 15 of belt subassembly 20 below, the cutting region side of laser cutting subassembly 14 is provided with side adsorption component 30 simultaneously.
Because belt assembly 20 sets up in the just right position of laser cutting subassembly 14, consequently the cutting region also is in belt assembly 20, and then produced dust and waste material can be directly adsorbed by belt assembly 20 when cutting the pole piece, the pole piece in cutting region also can be adsorbed fixedly by belt assembly, the shake when reducing the cutting.
Specifically, the belt assembly 20 includes a mounting frame 21 and a profiling belt 22 rotatably sleeved on the mounting frame 21, and the belt assembly 20 can adsorb and drive cutting waste or dust generated by the pole piece 10 cut from top to bottom, so as to periodically remove the cutting waste generated by cutting, and can collect dust on the side of the cutting area, thereby improving the working efficiency. The mounting frame 21 is of a box-shaped structure, a copying belt 22 is rotatably sleeved on the mounting frame 21 and revolves around the mounting frame, and a driving motor (not shown in the figure) is arranged at the lower part of the mounting frame 21 and is used for driving the copying belt 22 for adsorbing and cutting waste materials to run.
Referring to fig. 5, in the present embodiment, the path of the laser cutting is "<", the profiling belt 22 is correspondingly provided with profiling holes 221 having the same shape, the profiling holes 221 serve as through holes to penetrate through the whole profiling belt 22, and at least the profiling belt 22 is also provided with a profiling hole 221 at a corresponding position on the other side for the laser to smoothly pass through, so that the belt is prevented from being damaged during each cutting. That is, the profiling holes of the profiling belt 22 are formed in at least one pair in the laser light emission direction.
A plurality of adsorption holes 222 are uniformly arranged around the profiling hole 221, a trapezoidal sinking port is arranged on the side edge of the installation frame 21 and can be connected with the negative pressure air pipe 13, the adsorption holes 222 can generate negative pressure for adsorbing large cutting waste materials under the action of the negative pressure air pipe 13, and meanwhile, the adsorption holes 222 also absorb dust generated during cutting, so that the dust passes through the adsorption holes 222 to enter the installation frame 21 and is uniformly treated after being collected.
When the profile belt 22 does not meet the cutting requirement, that is, the sensor in the mounting frame 21 senses that the profile holes 221 or a certain number of the adsorption holes 222 are shielded by the cutting waste, and cannot meet the adsorption requirement for the next cutting, the driving motor rotates the driving profile belt 22 until the next profile hole 221 moves to the cutting area, so that the profile hole 221 which is currently collecting waste rotates to remove the adsorbed cutting waste and welding slag dust through the cleaning mechanism 15.
Of course, if the profile belt 22 is long enough, and a corresponding number of profile holes 221 can be added, the distance that the motor drives the profile belt 22 to move to the next profile hole 221 can be reduced. That is, the travel of the profiling belt 22 generated each time the motor is driven should ensure that the pair of profiling holes 221 are in a horizontal position and opposite to the laser cutting assembly, so that the laser emitted by the laser cutting assembly can pass through smoothly.
In another embodiment, an adsorption plate (not shown) capable of generating negative pressure is additionally disposed between the pole piece 10 and the laser cutting assembly 14, and is used for fixing the pole piece 10 during the transportation process of the pole piece, so that the pole piece is kept in a vertical state and is prevented from shaking during the cutting process, and the normal transportation of the pole piece is not affected. The laser cutting assembly 14 can cut the pole piece 10 by using laser to penetrate through the adsorption flat plate, and if the cutting is finished, the laser penetrates through the profiling hole 221. Therefore, the profiling belt 22, the pole piece 10, the suction plate and the laser cutting assembly 14 are coaxially arranged from left to right.
Meanwhile, the upper rotating roller 11 and the lower rotating roller 12 above the belt assembly 20 can ensure the layout mode of the pole piece 10, determine the feeding mode when the pole piece 10 is cut, and can also drive the pole piece 10 to cut by connecting with a driving motor. Of course, in other embodiments, the rotating rollers may not be arranged vertically, but may be arranged left and right or obliquely, so as to mainly meet the process requirements.
Referring back to fig. 1, the pole piece cutting device is further provided with a side adsorption component 30 located on the side of the cutting area, the adsorption area is increased by utilizing a funnel adsorption port 31, and meanwhile, a filter screen 32 is arranged at the end part of the funnel adsorption port 31 to ensure that the side adsorption component 30 is used for absorbing fine metal dust and particles diffused during cutting. Meanwhile, the adsorption holes 222 can adsorb large cutting waste generated during cutting, so that the large cutting waste is prevented from being adsorbed by the adsorption flat plate.
In one embodiment, referring to fig. 2, a cleaning mechanism 15 and a waste collecting assembly 40 are arranged right below the mounting frame 21, when the profile hole 221 does not meet the cutting requirement, the driving motor drives the profile belt 22 to rotate for a certain position, and the cleaning mechanism 15 which is located right below the belt assembly 20 and is tightly attached to the profile belt 22 can clean cutting waste adsorbed on the surface of the profile belt 22.
In this embodiment, this clearance mechanism is the brush, and its brush hair end laminates with the profile modeling belt mutually, therefore when the profile modeling belt rotates, the useless subassembly 40 of collection that the waste material and the dust adsorbed on it can be stopped and the clearance falls into the below by the brush, and this useless subassembly 40 of collection is located the clearance mechanism 15 under, and it can produce the negative pressure for the cutting waste material and the dust that drop can be collected through useless mouth 41 of funnel collection, and wherein useless mouth 41 of funnel collection can increase the absorption area of the useless subassembly 40 of collection, prevents the dust diffusion.
In summary, when the pole piece 10 passes around the upper rotating roller 11 and the lower rotating roller 12, a cutting area is formed between the two rollers, and the pole piece passing through the cutting area is adsorbed on the adsorption hole 222 on the belt assembly 20, so as to maintain a vertical state and maintain the stability of cutting. The laser cutting assembly 14 can cut the pole piece by using laser, and after the cutting is finished, the laser can penetrate through the cut pole piece 10 and the profiling hole 221, so that a cutting area on the belt assembly is avoided, the profiling belt 22 is prevented from being directly irradiated by the laser, and the service life is prolonged.
Meanwhile, a part of dust generated during cutting can be collected by the side adsorption component 30 located on the side of the cutting area, a small part of dust can pass through the adsorption hole 222 located on the profile modeling belt 22 and used for generating adsorption by the negative pressure air pipe 13, so that the dust is removed, meanwhile, large cutting waste generated during cutting can be adsorbed on the surface of the profile modeling belt 22 through the adsorption hole 222, when the sensor inside the installation frame 21 detects that the profile modeling hole 221 or a certain number of adsorption holes 222 are blocked by the large cutting waste, the profile modeling belt 22 can drive the adsorbed large cutting waste to rotate to the position under the belt component 20, and the cleaning mechanism 15 and the waste collection component 40 clean and collect the dust.
Because the profiling belt 22 on the belt assembly 20 in the scheme is provided with the profiling hole 221, the whole belt assembly 20 can be directly arranged at the position right opposite to the laser cutting assembly 14, and different from the prior art that the belt mechanism can only be arranged at the side lower part of the cutting area, the profiling belt 22 of the scheme is positioned in the cutting area, so that dust generated during cutting is directly adsorbed and collected by the belt assembly, and the generated cutting waste is directly adsorbed and fixed by the belt mechanism, the phenomenon of dust dispersion or waste scattering basically cannot be generated, and the cleaning degree during cutting is greatly improved.
Meanwhile, because the pole piece is directly attached to the belt assembly 20 during cutting, only the path of laser cutting is in a suspended state, and the upper and lower positions can be adsorbed on the adsorption holes 222 of the profiling belt 22, the suspended area during cutting of the pole piece is greatly reduced, the cutting is more stable, the cutting precision is improved, and the forming quality of a product is improved.
Certainly, in other embodiments, also can increase the absorption flat board and adsorb fixedly to the pole piece, with the cooperation of belt subassembly 20, stability when can further promote the pole piece cutting.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
