Description

Technical Field

[0001] This invention relates to the field of new energy-related component technology, and in particular to a deburring device and method for sheet materials. Background Technology

[0002] With the rapid development of new energy, the requirements for battery cell manufacturing are becoming increasingly stringent, and the process structure is becoming more and more complex. Currently, when lithium-ion battery electrodes are rolled and cut, the equipment operates at high speed, and the existing human eye cannot achieve precise inspection of the electrodes. Especially in mass production, problems such as deviation, high temperature, friction, and material spillage occur when the roll cutter rotates at high speed, resulting in a large number of small burrs and debris on the edges of the electrodes. This leads to unevenness on both sides of the battery cell and the possibility of foreign objects inside. In severe cases, it can cause short circuits and differential voltage problems in the battery cell.

[0003] Therefore, the desired solution is to enhance the cleaning of burrs and debris from the battery cell electrodes, reduce material and labor consumption, and ensure the yield rate and voltage difference of the battery cells. Summary of the Invention

[0006] A front-feeding mechanism is used to guide the horizontal transport of sheet materials.

[0007] Side burr removal mechanism, used to cut and deburr the sides of sheet materials on a horizontal conveying mechanism;

[0008] Upper and lower chip collection mechanism is used to collect chip residue from the upper and lower surfaces of the sheet material after side burr removal.

[0009] Demagnetizing components are used to demagnetize sheet materials after the top and bottom burrs have been removed.

[0010] The vibrating negative pressure cleaning mechanism is used to deburr demagnetized sheet materials by vibrating and applying negative pressure.

[0011] Preferably, it also includes a testing organization that performs burr inspection on the sheet material.

[0012] Preferably, the front guiding mechanism includes two sets of guiding components arranged opposite to each other. Each guiding component includes a horizontal moving mechanism and a mounting frame installed on the moving end of the horizontal moving mechanism. A guide wheel is vertically rotatably mounted on the mounting frame. The guide wheel has a guide ring groove. The guide wheels of the two sets of guiding components are arranged opposite to each other, and the guide grooves of the two sets of guide wheels support and guide the opposite sides of the sheet material.

[0013] Preferably, it further includes a heating mechanism, which is disposed between the front feeding mechanism and the side burr treatment mechanism, and is used to heat the material before it is processed by the side burr treatment mechanism.

[0014] Preferably, the side burr removal mechanism includes a rotary cutter, which includes a turntable. The turntable is vertically rotatably mounted on the frame, and a cutter is vertically rotatably mounted on the turntable.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1-3 The device shown is a deburring apparatus for sheet materials. This deburring apparatus is used to deburr electrode sheets. Specifically, the electrode sheets enter the apparatus after being rolled and slit. The apparatus includes a frame 1 and components mounted on the frame 1.

[0040] The front feeding mechanism 2 is used to guide the horizontal transmission of sheet materials. The setting of this feeding mechanism ensures the accuracy of the subsequent side burr treatment mechanism and other processes for the treatment of electrode burrs.

[0041] The side burr removal mechanism is used to cut and deburr the sides of the sheet material on the horizontal conveying mechanism. The side burr removal mechanism removes the burrs on the sides of the electrode sheet by cutting.

[0042] The upper and lower chip processing mechanism 4 is used to collect the chip residue on the upper and lower surfaces of the sheet material after the side burr treatment. After the side burr treatment mechanism cuts the side of the electrode sheet, some chip residue will be adsorbed onto the upper and lower surfaces of the electrode sheet. The upper and lower chip processing mechanism 4 partially adsorbs the chip residue on the upper surface of the electrode sheet.

[0043] Demagnetizing component 5 is used to demagnetize the sheet material after the upper and lower burrs are processed, remove static electricity and prevent the residue from being adsorbed on the electrode sheet by static electricity. This demagnetizing component 5 can be the contact type demagnetizing component 5 in the prior art.

[0044] The vibrating negative pressure cleaning mechanism is used to vibrate and apply negative pressure to deburr demagnetized sheet materials. The vibration mechanism causes the electrode sheets to vibrate, which facilitates the collection and processing of residues.

[0045] Preferably, a testing organization is used to inspect the sheet material for burrs.

[0046] like Figure 1 , Figures 3-4 As shown, preferably, the front guiding mechanism 2 includes two sets of guiding components arranged opposite to each other. The guiding components include a horizontal moving mechanism 7 and a mounting frame 8 installed on the moving end of the horizontal moving mechanism 7. A guide wheel 9 is vertically rotatably mounted on the mounting frame 8. The guide wheel 9 has a guide ring groove 90. The guide wheels 9 of the two sets of guiding components are arranged opposite to each other, and the guide grooves of the two sets of guide wheels 9 support and guide the opposite sides of the sheet material. It should be noted that the horizontal moving mechanism 7 can be an electric cylinder, a pneumatic cylinder, or other mechanism that can drive the components to move horizontally, as is available in the prior art.

[0047] like Figure 4 Preferably, the width of the guide groove gradually increases from the side closer to the axis of the guide wheel 9 to the side farther away from the guide wheel 9, that is, the guide groove is a V-shaped annular groove, which facilitates the guidance of materials.

[0048] like Figure 1As shown, in order to further increase the deburring accuracy, in some embodiments, a first position detection element 10 is preferably included. The first material position detection element is a laser sensor. The laser sensor is used to detect the position of the sheet material. If the electrode deviates to the right or left relative to the frame 1, the horizontal moving mechanism 7 drives the guide wheel 9 to move and adjust the sheet material. At the same time, the setting of two sets of guide components further facilitates the adjustment of the position of the sheet material and can adapt to materials of different widths.

[0049] like Figure 3 , Figure 1 As shown, preferably, it also includes a heating mechanism 11, which is disposed between the front feeding mechanism 2 and the side burr treatment mechanism. It is used to heat the material before the side burr treatment mechanism processes it. The heating mechanism 11 is mounted on the frame 1 and includes an upper heating pipe and a lower heating pipe. The upper heating pipe and the lower heating pipe are rotatably mounted on the frame 1. A feeding channel is formed between the upper heating pipe and the lower heating pipe. The sheet material passes through the feeding channel, and heating gas is introduced into the upper heating pipe and the lower heating pipe to achieve the heating of the sheet material. It should be noted that the heating mechanism 11 and the side burr treatment mechanism are located on the same side of the sheet material.

[0050] Furthermore, the upper and lower heating tubes can also be heated by existing electric heating elements to achieve the heating of sheet materials.

[0051] like Figure 6 , Figure 7 As shown, preferably, the side burr removal mechanism includes a rotary cutter 3, which includes a turntable 30. The turntable 30 is vertically rotatably mounted on the frame 1, and a cutter 31 is vertically rotatably mounted on the turntable 30. The cutter 31 has a cutting portion extending outward from the turntable 30. Preferably, at least two sets of cutters 31 are provided, and at least two sets of cutters 31 are circumferentially distributed on the turntable 30. Specifically, the cutter 31 is radially inclined relative to the turntable 30, but the axis of rotation of the cutter 31 relative to the turntable 30 is parallel to the axis of the turntable 30.

[0052] In some embodiments, the sides of the heated sheet material are preferably deburred to further enhance the deburring effect.

[0053] like Figure 6-7 Preferably, the rotary cutter 3 is provided with at least two sets, and the two adjacent sets of rotary disks 30 rotate in opposite directions, as shown in the figure. Any two adjacent rotary cutters 3 are tilted at opposite angles relative to the rotary disks 30, thereby further increasing the burr removal effect. In this figure, the rotary cutter 3 is provided with two sets, and the two sets of rotary cutters 3 are driven by a gear transmission mechanism, thereby ensuring that the two sets of rotary cutters 3 rotate in opposite directions.

[0054] like Figure 1 As shown, preferably, it also includes a debris removal component 12 disposed in the side burr treatment mechanism, the debris removal component 12 being used to adsorb the debris removed by the side burr treatment mechanism.

[0055] Preferably, such as Figure 1 , Figure 5 As shown, the impurity removal component 12 includes an upper air blowing pipe 120, a lower air blowing pipe 121, and a first side adsorption pipe 122. The air outlet of the upper air blowing pipe 120 is located above the side burr treatment mechanism, the air outlet of the lower air blowing pipe 121 is located below the side burr treatment mechanism, and the air inlet of the first side adsorption pipe 122 is located on the side of the side burr treatment mechanism away from the sheet material and opposite to the sheet material. The upper air blowing pipe 120 and the lower air blowing pipe 121 facilitate the blowing of the cut-off debris, and at the same time blow the uncut burrs to facilitate the cutter 31 to remove the burrs. Meanwhile, the first side adsorption pipe 122 adsorbs the cut-off debris.

[0056] like Figure 5 As shown, preferably, it also includes an adsorption hood, which includes an upper adsorption hood 13, a side adsorption hood 14, and a lower adsorption hood 15. The upper adsorption hood 13 and the lower adsorption hood 15 are mounted on the frame 1, with the upper adsorption hood 13 located above the side burr treatment mechanism and the lower adsorption hood 15 located below the side burr treatment drum. The side adsorption hood 14 is located on the side of the side burr treatment mechanism away from the sheet material, and the upper adsorption hood 13 and the lower adsorption hood 15 are located above and below the sheet material, respectively. The air inlet of the first side adsorption pipe 122 extends into the side adsorption hood 14, the air outlet of the upper blowing pipe 120 is located inside the upper adsorption hood 13, and the air outlet of the lower blowing pipe 121 extends into the lower adsorption hood 15.

[0057] After the sides of the sheet material are cut off, some residue may adhere to the top and bottom of the sheet material. This is especially true in some embodiments where an upper air pipe 120 and a lower air pipe 121 structure are used, resulting in residue on both the upper and lower surfaces of the sheet material. Figure 6 , Figure 8 As shown, preferably, the upper and lower debris handling mechanism 4 includes an upper brush 40 and a lower brush 41 that are laterally rotatably mounted on the frame 1. The axis of rotation of the upper brush 40 and the lower brush 41 relative to the frame 1 is along the width direction of the sheet material and perpendicular to the electrode conveying direction. The upper brush 40 is located above the sheet material and in contact with the upper surface of the sheet material, and the lower brush 41 is located below the sheet material and in contact with the lower surface of the sheet material. The upper brush 40 and the lower brush 41 rotate in opposite directions. It should be noted that the upper brush 40 and the lower brush 41 are non-marking brushes.

[0058] like Figure 8As shown, the frame 1 is also provided with an upper scraper 16 and a lower scraper 17. The upper scraper 16 has a portion extending into the upper brush 40 and scrapes off the waste in the upper brush 40. The lower scraper 17 has a portion extending into the lower brush 41 and scrapes off the waste in the lower brush 41.

[0059] like Figure 8 As shown, in order to further increase the impurity removal effect, the frame 1 is also provided with a second side adsorption tube 18. The second side adsorption tube 18 is opposite to the upper brush 40 and the lower brush 41 and is used to adsorb impurities in the upper brush 40 and the lower brush 41. It also adsorbs the waste debris brushed off by the upper brush 40 and the lower brush 41.

[0060] Specifically, the upper brush 40 and the lower brush 41 can be driven by a gear transmission mechanism in the prior art, thereby causing the upper brush 40 and the lower brush 41 to rotate in opposite directions.

[0061] like Figure 1 As shown, preferably, it also includes a lifting mechanism 19 and a lifting frame 20. The upper brush 40 and the lower brush 41 are both installed on the lifting frame 20, and the upper brush 40 and the lower brush 41 are on the lifting frame 20. The lifting mechanism 19 is installed on the frame 1 and the lifting frame 20 is installed on the lifting end of the lifting mechanism 19. The lifting mechanism 19 drives the lifting frame 20 to rise and fall in the vertical direction, thereby adjusting the position of the upper brush 40 and the lower brush 41 relative to the sheet material to ensure the impurity removal effect.

[0062] like Figure 1 As shown, preferably, the positions of the lifting frame 20 and the lifting mechanism 19 on the frame 1 along the width direction of the sheet material can be adjusted, thereby facilitating the adjustment of the horizontal positions of the upper brush 40 and the lower brush 41;

[0063] like Figure 1 As shown, specifically, the frame 1 is provided with a slide rail 21, and a slider 22 is slidably mounted on the slide rail 21. The lifting mechanism 19 is mounted on the slider 22, and the slider 22 is fixed to the slide rail 21 by components such as fixing pins or fixing screws in the prior art.

[0064] like Figure 2 , Figure 9As shown, preferably, the vibration negative pressure cleaning mechanism includes a negative pressure adsorption component 60 and a vibration component 61. The negative pressure adsorption component 60 includes a negative pressure tube and a sealing cover. The sealing cover is installed on the frame 1 and located above the sheet material. The vibration component 61 includes a mounting shaft 610 and a vibration wheel 611. The mounting shaft 610 is rotatably mounted on the frame 1, and the vibration wheel 611 is rotatably mounted on the mounting shaft 610. The axis of rotation of the vibration wheel 611 relative to the mounting shaft 610 is parallel to the axis of rotation of the mounting shaft 610 relative to the frame 1. Rotating the mounting shaft 610 causes the vibration wheel 611 to contact or disengage from the sheet material, causing the sheet material to vibrate up and down. The axial direction of the mounting shaft 610 is along the width direction of the sheet material and perpendicular to the direction of horizontal transmission of the sheet material.

[0065] like Figure 9 As shown, preferably, a mounting plate 612 is mounted on the mounting shaft 610, and a vibrating wheel 611 is mounted on the mounting plate 612. Each mounting plate 612 is equipped with at least two sets of vibrating wheels 611. The at least two sets of vibrating wheels 611 are circumferentially distributed around the mounting shaft 610 with the mounting shaft 610 as the center. A vibration space is formed between any two adjacent sets of vibrating wheels 611. As shown in the figure, each set of mounting plates 612 in this application is equipped with three sets of vibrating wheels 611. Preferably, the mounting plates 612 on the mounting shaft 610 are provided with at least two sets, and each set of mounting plates 612 is equipped with a vibrating wheel 611, thereby increasing its vibration effect.

[0066] like Figure 9 As shown, the portion of the sealing cover corresponding to the frame 1 is the vibration impurity removal zone. The sheet material in this zone is vibrated up and down by the vibration assembly 61 while impurities are adsorbed by the negative pressure pipe. Specifically, the frame 1 is also equipped with a front upper pressure roller 23 and a front lower support roller 24. The front upper pressure roller 23 is located above the sheet material, and the front lower support roller 24 is located below it. Below the frame 1, there is also a rear upper pressure roller 25 and a rear lower support roller 26. The rear upper pressure roller 25 is located above the sheet material, and the rear lower support roller 26 is located below it and supports the sheet material. The front upper pressure roller 23, front lower support roller 24, and rear upper pressure roller 25... Both the front upper pressure roller 23 and the front lower support roller 24 are laterally rotatable on the frame 1 along the width direction of the sheet material. The front upper pressure roller 23 and the front lower support roller 24 are located in front of the mounting shaft 610. Preferably, the front upper pressure roller 23 is located behind the front lower support roller 24, the rear lower support roller 26 is located behind the rear upper pressure roller 25, and the rear upper pressure roller 25 and the rear lower support roller 26 are located behind the mounting shaft 610. That is, during the processing, the sheet material comes into contact with the front lower support roller 24, the front upper pressure roller 23, the vibrating wheel 611 on the mounting shaft 610, the rear upper pressure roller 25, and the rear upper pressure roller 25 in sequence. Sheet materials not located in the impurity removal zone can be horizontally transported.

[0067] like Figure 2As shown, preferably, the sealing cover includes an upper sealing cover 600 and a lower sealing cover 601, and the negative pressure pipe includes an upper negative pressure pipe 602 and a lower negative pressure pipe 603. Both the upper sealing cover 600 and the lower sealing cover 601 are mounted on the frame 1. The upper sealing cover 600 is located above the sheet material, and the lower sealing cover 601 is located below the sheet material. A vibration space is formed between the upper sealing cover 600 and the lower sealing cover 601. The sheet material located in the vibration impurity removal zone vibrates in the vibration space. The air inlet of the upper negative pressure pipe 602 is located inside the upper sealing cover 600, and the air inlet of the lower negative pressure pipe 603 is located inside the lower sealing cover 601, further increasing the impurity removal effect.

[0068] like Figure 9 As shown, preferably, it also includes a belt drive mechanism 27, which is installed between the mounting shaft 610, the front upper pressure roller 23 and the rear upper pressure roller 25. During the rotation of the mounting shaft 610, the front upper pressure roller 23 and the rear upper pressure roller 25 also rotate, further increasing the transmission and impurity removal effect.

[0069] like Figure 9 As shown, preferably, the demagnetizing component 5 is located between the front lower support plate and the mounting shaft 610.

[0070] like Figure 9 , Figure 3 As shown, preferably, the frame 1 is also provided with a rear guide mechanism 28 and a front guide mechanism 2 for guiding the horizontal transmission of sheet materials. As shown in the figure, the structure of the rear guide mechanism 28 is the same as that of the front guide mechanism 2, both including two sets of guide components arranged opposite to each other.

[0071] Preferably, the device also includes a second position detection element 29, which is a laser sensor. The laser sensor is used to detect the position of the sheet material. If the electrode deviates to the right or left relative to the frame 1, the rear guide mechanism 28 adjusts the sheet material.

[0072] The detection mechanism includes a CCD camera 34. The second position detection element 29 and the CCD camera 34 are located between the vibration negative pressure cleaning mechanism and the rear material guide mechanism 28. The second position detection element 29 and the CCD camera 34 detect the cleaned electrode sheet. The second position detection element 29 and the CCD camera 34 are connected to the information processor 32. The information processor 32 is also connected to the indicator light 33. The second position detection element 29 is a laser sensor that transmits the detection information to the information processor 32. If the electrode sheet is in the correct position and there is no fault, the information processor 32 controls the CCD camera 34 to take a picture. If there is an abnormality in the captured picture, the information processor 32 controls the indicator light 33 to alarm. The CCD camera 34 is also connected to a display. The CCD camera 34 transmits the captured image to the display for subsequent coding and marking for processing.

[0073] A deburring device and method for sheet materials, used to deburr electrode sheets, comprising the following steps:

[0074] S1: After passing through the slitting and pressing roller mechanism, the electrode sheet enters the above-mentioned device. After the first position detection element 10 detects the position of the electrode sheet, if the electrode sheet deviates relatively, the horizontal moving mechanism 7 moves horizontally to adjust the position of the electrode sheet. The heating mechanism 11 heats the electrode sheet to reduce the humidity of the burrs. Then, the rotating rotary cutter 3 performs burr cutting on the side of the sheet material. Preferably, during the burr cutting process, the upper air pipe 120 and the lower air pipe 121 blow air in the direction of the rotary cutter 3 to make the burrs extend outward relative to the sheet material. The first side adsorption pipe 122 draws air to absorb the waste.

[0075] S2: The upper and lower parts of the sheet material are deburred by brushes, and the upper and lower surfaces of the sheet material are cleaned by upper brush 40 and lower brush 41. At the same time, the second side adsorption tube 18 adsorbs the waste debris cleaned by upper brush 40 and lower brush 41.

[0076] S3: Demagnetize the sheet material: Demagnetize the sheet material through the demagnetizing component 5;

[0077] S4: Vibrate the sheet material and adsorb the debris under the vibration of the sheet material through the negative pressure tube. The vibration component 61 vibrates the sheet material up and down, and the adsorption component adsorbs the debris in the process of the sheet material vibrating up and down.

[0078] Preferably, the process also includes step S5: the cleaned electrode sheet is inspected by the second position detection element 29 and the CCD camera 34, the CCD camera 34 takes a picture of the electrode sheet, and if there are at least two abnormalities on one side of the captured information, the information processor 32 controls the indicator light 33 to alarm, and the CCD camera 34 transmits the captured image to the display, marks it with a code and waits for processing.
