DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Example: Figure 1 - Figure 6As shown, the sawing and deburring device of the extruded battery cell shell production line includes a first conveyor belt 2, a transport conveyor belt 1 is installed on the right side of the first conveyor belt 2, a feeding device 3 is installed above the first conveyor belt 2, a fixing device 4 is installed on the front side of the first conveyor belt 2, a cutting machine 5 is installed at the front end of the first conveyor belt 2, a second conveyor belt 7 is installed on the left side of the first conveyor belt 2, and grinding devices are installed on the front and rear sides of the second conveyor belt 7, and the grinding device extends to one side of the first conveyor belt 2; the grinding device includes a double-axis moving platform 6, the output end of the double-axis moving platform 6 is fixedly connected to the first bracket 8 and the second bracket 9, the ends of the first bracket 8 and the second bracket 9 are fixedly connected to the pneumatic telescopic rod 10, the two pneumatic telescopic rods 10 are symmetrical up and down, the output end of the pneumatic telescopic rod 10 is fixedly connected to the clamping plate 11, and the middle part of the first bracket 8 is fixedly connected to the telescopic electric cylinder 39, and the output end of the telescopic electric cylinder 39 extends to the inner side of the first bracket 8, and the output end of the telescopic electric cylinder 39 is fixedly connected to the grinding mechanism. The whole device is controlled by the PLC system. The grinding device is installed with a camera and a laser rangefinder, and is connected to the control system for positioning the product. The first conveyor belt 2 pushes the aluminum alloy tube through the feeding device 3, and the second conveyor belt 7 contains a power device. The second conveyor belt 7 transports the product by itself. The feeding device 3 includes a screw nut mechanism and a push plate. The screw nut mechanism drives the push plate to move, and the push plate acts on the end of the aluminum alloy tube. The fixing device 4 includes a lifting cylinder and a pressing plate. The lifting cylinder contracts to press the pressing plate on the upper surface of the aluminum alloy tube to fix the aluminum alloy tube. A conveyor belt is arranged on the right side of the rear grinding device. The battery core shell after deburring falls on the conveyor belt and is transported to the next process.

[0031] The extruded hollow aluminum alloy tube is transported to the first conveyor belt 2 by the transport conveyor belt 1. The feeding device 3 acts on the end of the aluminum alloy tube to push the tube to move in the direction of the cutting machine 5. The feeding device 3 pushes the tube quantitatively, and then the fixing device 4 fixes the tube. The grinding mechanism moves to the end of the tube under the action of the double-axis moving platform 6, so that the two clamps 11 are located on the upper and lower sides of the tube. The pneumatic telescopic rod 10 works to clamp the clamps 11 on both sides of the tube, and cooperates with the fixing device 4 to make the tube more stable, reduce the burrs on the cut section of the battery cell shell, and when cutting the tube, the telescopic electric cylinder 39 sends the grinding mechanism to the end of the tube to grind one side of the battery cell shell, and then the battery cell shell with one side polished is sent to the next grinding device through the second conveyor belt 7 to grind the other side. After the sawing is completed, the deburring operation is immediately performed, thereby improving the production efficiency of the battery cell shell.

[0032] Specifically, refer to Figure 3 and Figure 4The grinding mechanism includes a mounting plate 13, a mounting block 16 is slidably connected to the middle of the mounting plate 13, and the mounting block 16 is fixedly installed at the output end of the telescopic electric cylinder 39. A mounting groove 24 is provided on the side of the mounting block 16. The mounting groove 24 has the same shape as the end surface of the battery core shell. A plurality of motors 25 are slidably connected inside the mounting groove 24. A friction wheel 26 is fixedly connected to the output end of the motor 25. The motor 25 drives the friction wheel 26 to rotate when it works. The rotating friction wheel 26 contacts the cut end surface of the battery core shell under the action of the telescopic electric cylinder 39 to perform a deburring operation.

[0033] For further reference, Figure 5 and Figure 6 The output shaft of the motor 25 is fixedly connected with a driving gear 35, and the outer side of the driving gear 35 is meshed with a transmission gear 36, and the outer side of the transmission gear 36 is meshed with an inner and outer gear ring 37, and the outer side of the inner and outer gear ring 37 is meshed with an annular rack 38, and the annular rack 38 is arranged along the mounting groove 24, and the transmission gear 36 and the inner and outer gear ring 37 are both rotatably connected to the end of the motor 25, and a positioning sleeve 34 is fixedly connected to the output shaft of the motor 25, and the positioning sleeve 34 is movably installed at the notch position of the mounting groove 24. The working of the motor 25 drives the driving gear 35 to rotate, and the driving gear 35 rotates the inner and outer gear rings 37 through the transmission gear 36. The rotating inner and outer gear rings 37 are subjected to the reaction force of the annular rack 38, so that the motor 25 and the friction wheel 26 move along the mounting groove 24, so that the entire end surface of the core shell of the friction wheel 26 is deburred.

[0034] Specifically, Figure 5 As shown, four first motors are fixedly installed on the side of the mounting block 16, and the output ends of the four first motors are fixedly connected to the first rollers 27. The outer sides of the four first rollers 27 are installed with first friction belts 28. The inner surface of the first friction belt 28 is a toothed belt, and the outer surface of the first friction belt 28 is provided with a plurality of elastic protrusions, and the surface of the elastic protrusions is provided with hard particles. When the mounting block 16 moves toward the battery cell shell, the first friction belt 28 is inserted into the interior of the battery cell shell, and the four first motors work simultaneously to rotate the first rollers 27, thereby moving the first friction belt 28, grinding the inner wall of the battery cell shell, and performing deburring operations. The setting of the elastic protrusions allows the size of the first friction belt 28 to be slightly smaller than the internal size of the battery cell shell, so that the first friction belt 28 can enter the battery cell shell conveniently.

[0035] Specifically, Figure 5As shown, four second motors are fixedly installed on the side of the mounting plate 13, and the output ends of the four second motors are fixedly connected to the second rollers 29. The outer sides of the four second rollers 29 are installed with second friction belts 30. The second friction belts 30 have a certain elasticity. When the telescopic electric cylinder 39 pushes the mounting block 16 and the mounting plate 13 toward the battery cell shell, the second friction belts 30 are covered on the outer wall of the battery cell shell. The four second motors work to drive the four second rollers 29 to rotate, thereby moving the second friction belts 30 to deburr the outer wall of the battery cell shell.

[0036] Preferably, reference Figure 2 , Figure 4 and Figure 5 , both sides of the second rotating roller 29 are provided with limiting rollers 31, and one end of the limiting roller 31 facing the mounting plate 13 is fixedly connected to a connecting arm 32, and the end of the connecting arm 32 is fixedly connected to a notched gear 33, and the notched gears 33 are rotatably connected to the outside of the mounting plate 13, and the two notched gears 33 are meshed with each other, and the four corners of the mounting block 16 are hinged with a push rod 20, and the end of the push rod 20 is hinged with a spur rack 21, and the side of the spur rack 21 is meshed with a driving gear 22, and the driving gear 22 is fixedly connected to one of the notched gears 33 in the relative position, and the spur rack 21 is away from the driving gear 22. A guide rail 23 is slidably connected to one side of the moving gear 22, and the guide rail 23 is fixedly connected to the outer side of the mounting plate 13. A pair of limit plates 12 are fixedly connected to the inner side of the first bracket 8. The pair of limit plates 12 are respectively arranged on the upper and lower sides of the mounting plate 13. The ends of the limit plates 12 are provided with bends. The two limit plates 12 are arranged on the upper and lower sides of the mounting plate 13 to support and limit the mounting plate 13, thereby reducing the radial load of the telescopic electric cylinder 39 and making the movement of the grinding mechanism more stable. A lateral moving platform is installed below the cutting machine 5 to enable the cutting machine 5 to move laterally to saw the pipe;

[0037] When the telescopic electric cylinder 39 pushes the grinding mechanism toward the battery cell shell, when the second friction belt 30 completely overlaps with the battery cell shell, the mounting plate 13 and the bending part of the limit plate 12 are against each other. At this time, the telescopic electric cylinder 39 continues to extend, and the mounting block 16 moves toward the battery cell shell until the friction wheel 26 is against the end face of the battery cell shell, and the first friction belt 28 is completely overlapped with the inner wall of the battery cell shell. The moving mounting block 16 acts on the push rod 20 to reduce the angle between the push rod 20 and the vertical plane, so that the push rod 20 pushes the spur rack 21 to slide along the guide rail 23. The moving spur rack 21 acts on the driving gear 22 and rotates it. The rotating driving gear 22 drives one of the notched gears 33 to rotate, so that the two notched gears 33 rotate synchronously, so that the connecting arm 32 moves inward, and then the limit roller 31 squeezes the second friction belt 30 and moves toward the outer wall of the battery cell shell, so that the second friction belt 30 is fully in contact with the outer wall of the battery cell shell, thereby improving the deburring effect.

[0038] Specifically, Figure 4As shown, the four sides of the mounting block 16 are fixedly connected with sliders 17, and the sliders 17 are slidably connected to the inner side of the mounting plate 13. The ends of the sliders 17 are fixedly connected with stoppers 18, and an elastic telescopic rod 19 is installed between the stoppers 18 and the mounting plate 13. When the mounting block 16 moves in the middle of the mounting plate 13, the sliders 17 slide along the mounting plate 13 and cooperate with the stoppers 18 to squeeze the elastic telescopic rod 19, so that the elastic telescopic rod 19 contracts. After the grinding is completed, the elastic telescopic rod 19 acts on the mounting plate 13 to reset the mounting plate 13 and the mounting block 16, thereby resetting the second friction belt 30.

[0039] Specifically, Figure 3 As shown, a pair of guide posts 14 are fixedly connected to one side of the mounting block 16 facing the first bracket 8, and an ear plate 15 is slidably connected to the outer side of the guide post 14, and the ear plate 15 is fixedly connected to the outer side of the first bracket 8. During the movement of the grinding mechanism, the guide post 14 slides along the ear plate 15, thereby making the movement of the grinding mechanism more stable.

[0040] Working principle: The extruded hollow aluminum alloy tube is transported to the first conveyor belt 2 through the transport conveyor belt 1. The feeding device 3 acts on the end of the aluminum alloy tube to push the tube toward the cutting machine 5. The feeding device 3 pushes the tube quantitatively so that the tube exceeds the length of the cutting machine 5 to load the length of the battery core shell, and then the fixing device 4 works to fix the tube;

[0041] The dual-axis mobile platform 6 drives the first bracket 8 and the second bracket 9 to move, so that the two clamping plates 11 are located at the upper and lower sides of the pipe, and the pneumatic telescopic rod 10 works to clamp the clamping plates 11 on both sides of the pipe to further fix the pipe, and then the cutting machine 5 works to saw the pipe to make a battery core shell;

[0042] When the battery shell is cut out, the telescopic electric cylinder 39 works to push the mounting block 16 and the mounting plate 13 toward the battery shell. First, the second friction belt 30 is wrapped around the outside of the battery shell. When the second friction belt 30 completely overlaps with the battery shell, the mounting plate 13 and the bending part of the limit plate 12 are against each other. At this time, the telescopic electric cylinder 39 continues to extend, and the mounting block 16 moves toward the battery shell until the friction wheel 26 is against the end face of the battery shell, and the first friction belt 28 is completely overlapped with the inner wall of the battery shell. The mounting block 16 acts on the push rod 20, so that the angle between the push rod 20 and the vertical plane becomes smaller, so that the push rod 20 pushes the spur rack 21 to slide along the guide rail 23, and the moving spur rack 21 acts on the driving gear 22 and makes it rotate. The rotating driving gear 22 drives one of the notched gears 33 to rotate, so that the two notched gears 33 rotate synchronously, so that the connecting arm 32 moves inward, so that the limiting roller 31 squeezes the second friction belt 30, and the second friction belt 30 is fully in contact with the outer wall of the battery core shell;

[0043] The motor 25 drives the friction wheel 26 and the driving gear 35 to rotate, and the driving gear 35 rotates the inner and outer gear rings 37 through the transmission gear 36. The rotating inner and outer gear rings 37 are subjected to the reaction force of the annular rack 38, so that the motor 25 and the friction wheel 26 move along the installation groove 24, so that the friction wheel 26 deburrs the end surface of the entire battery core shell;

[0044] The four first motors work simultaneously to rotate the first roller 27, thereby moving the first friction belt 28 to deburr the inner wall of the battery cell shell. The four second motors work to drive the four second rollers 29 to rotate, thereby moving the second friction belt 30 to deburr the outer wall of the battery cell shell.

[0045] After deburring one end of the cell shell, the cell shell is placed on the second conveyor belt 7 and transported to the rear grinding device, and the above-mentioned action is repeated to deburr the other end surface of the cell shell. After the deburring operation on the other end is completed, the cell shell is sent to the next process via the conveyor belt.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
