Description

Ultra-high-speed dual cutting system for secondary battery electrode plates equipped with feeding correction function and ultra-high-speed dual cutting method for secondary battery electrode plates

[0001] The present invention relates to a secondary battery electrode plate ultra-high-speed dual cutting system and a secondary battery electrode plate ultra-high-speed dual cutting method equipped with a feeding correction function. More specifically, the invention relates to a secondary battery electrode plate ultra-high-speed dual cutting system and a secondary battery electrode plate ultra-high-speed dual cutting method equipped with a feeding correction function implemented to enable a fast electrode plate transfer speed and rapid electrode plate cutting operation.

[0002]

[0003] A secondary battery is manufactured by stacking a separator at the bottom, a positive plate on top of it, a separator on top of a single positive plate, a negative plate on top of the separator, another positive plate on the upper surface of the separator on the negative plate, and then sequentially stacking the separator and negative plate alternately.

[0004] Meanwhile, for the manufacture of secondary batteries, electrode plates wound in a roll form are supplied along a conveyor line and notched by a notching unit to form tabs on the electrode plates. After the tabs are formed into rectangular electrode plates by a cutter unit and the rectangular electrode plates undergo vision inspection by a vision unit, they are transported by the operation of a conveyor belt so that they can be loaded into a stack magazine.

[0005] At this time, a cutter unit is required to form a square-shaped electrode plate by notching the electrode plate with a notching unit while supplying it along a transfer line and cutting the electrode plate with the formed tabs, and an electrode plate feeding and cutting unit is required for transferring and cutting the electrode plate to create a square-shaped electrode plate.

[0006] The existing sub-feeding unit is structured such that the sub-feeding roller moves up and down by driving a motor and a cam, the drive roller operates by contacting the conveyor belt, and the sub-feeding roller rotates and conveys the electrode plate after pressing it.

[0007] However, there is a problem in that the electrode plate cutting operation slows down at the same rate as the plate transport speed because the transport speed of the electrode plates is relatively slow. This is disadvantageous in terms of productivity, and since the production line's production operations are also slow, these factors also cause delays in the electrode plate cutting operation and are disadvantageous in terms of productivity.

[0008]

[0116]

[0117] According to the present invention with the above configuration, when the motor shaft of the first cam drive motor (164) of the first cutting unit (120) rotates in one direction (e.g., clockwise) and the first upper cutter lifting cam (162) rotates in one direction (e.g., clockwise), the leading edge of a pair of first levers (165) rotates upward, causing the first upper cutting support bracket (167) and the first upper cutter (125) to rise; and when the motor shaft of the first cam drive motor (164) rotates in the other direction (e.g., counterclockwise) and the first upper cutter lifting cam (162) rotates in the other direction (e.g., counterclockwise), the leading edge of a pair of first levers (165) moves downward, causing the first upper cutting support bracket (167) and the first upper cutter (125) to descend. It works.

[0118] Meanwhile, when the motor shaft of the second cam drive motor (174) of the above-mentioned rotating body operating unit rotates in one direction (e.g., clockwise) and the second upper cutter lifting cam (172) rotates in one direction (e.g., clockwise), the leading edge of a pair of second levers (175) rotates upward, causing the second upper cutting support bracket (177) and the second upper cutter (135) to rise. When the motor shaft of the second cam drive motor (174) rotates in the other direction (e.g., counterclockwise) and the second upper cutter lifting cam (172) rotates in the other direction (e.g., counterclockwise), the leading edge of a pair of second levers (175) moves downward, causing the second upper cutting support bracket (177) and the second upper cutter (135) to descend.

[0119] The first cutting unit (120) and the second cutting unit (130) of the above configuration are configured to operate simultaneously.

[0120] The first upper cutter (125) and the second upper cutter of the first cutting unit (120) and the second cutting unit (130), respectively, are raised simultaneously, and then the electrode plate is transported between the first upper cutter (125), the first lower cutter (126), the second upper cutter (135), and the second lower cutter (136) of the first cutting unit (120) and the second cutting unit (130) by the suction pressure acting in the multiple suction holes of the conveyor belt (152) running on the endless track of the conveyor and the multiple frame-side suction holes of the conveyor frame and the multiple transfer rollers (140). In this state, the first upper cutter (125) and the second upper cutter of the first cutting unit (120) and the second cutting unit (130), respectively, are lowered simultaneously again, and the first upper cutter (125) and the first lower cutter (126) and Dual cutting is performed by simultaneously cutting both sides of the electrode plate using the second upper cutter (135) and the second lower cutter (136).

[0121] Accordingly, the present invention has the effect of enabling ultra-high-speed dual cutting by simultaneously cutting both sides of the electrode plate by the first cutting unit (120) and the second cutting unit (130).

[0122] Additionally, the present invention further includes a first cutting contact driving unit and a second cutting contact driving unit that bring the first upper cutter (125) and the second upper cutter (135) into contact with the first lower cutter (126) and the second lower cutter (136), respectively.

[0123] At this time, the first cutting contact drive unit includes a first cutting contact cylinder (223) mounted on the first cutting support bracket (122) and having a cylinder rod arranged in a vertical direction, and a first cutter contact operating bracket (224) provided on the first cutting connection bracket (124) connected to the first cutting support bracket (122) via a first horizontal hinge (123) and positioned so as to be pressed by the cylinder rod of the first cutting contact cylinder (223).

[0124] The first cutting contact cylinder (233) is mounted on the main support frame (110). The cylinder rod of the first cutting contact cylinder (233) presses the first cutting support bracket (122) downward, thereby rotating the first cutting support bracket (122) toward the first lower cutter (126) with respect to the first horizontal hinge (123) connected to the main support frame (110), so that the first upper cutter (125) is in contact with the first lower cutter (126). The inner surface of the first upper cutter (125) is in contact with the inner surface of the first lower cutter (126). See FIG. 31.

[0125] Additionally, the second cutting close drive unit includes a second cutting close cylinder (233) mounted on the second cutting support bracket (132) and having a cylinder rod positioned horizontally, and a second cutter close operating bracket (234) provided on the main support bracket and positioned so as to be pressed by the cylinder rod of the second cutting close cylinder (233).

[0126] The second cutting contact cylinder (233) is mounted on the main support frame (110). The cylinder rod of the second cutting contact cylinder (233) pushes the second cutting support bracket (132) in a horizontal direction, thereby rotating the second cutting support bracket (132) so that it is pushed relative to the second horizontal hinge (133) connected to the main support frame (110), so that the second upper cutter (135) is in close contact with the second lower cutter (136). The inner surface of the second upper cutter (135) is in close contact with the inner surface of the second lower cutter (136). See FIG. 31.

[0127] Accordingly, when cutting both sides of a electrode plate using the first upper cutter (125), the first lower cutter (126), the second upper cutter (135), and the second lower cutter (136), the first upper cutter (125) and the first lower cutter (126) are always in close contact, and the second upper cutter (135) and the second lower cutter (136) are also always in close contact, so that the effect of reliably preventing cutting defects of the electrode plate when dual cutting both sides of the electrode plate can be expected.

[0128] Additionally, according to the present invention, if a feeding misalignment occurs while the electrode plate is being transported along the transport line of the main support frame (110), the first feeding correction drive pulley and the first feeding correction driven pulley rotate in forward and reverse directions by the driving of the first correction drive motor (202) and the second correction drive motor (212), thereby rotating the first correction ball screw (207), and simultaneously the second feeding correction drive pulley and the second feeding correction driven pulley rotate in forward and reverse directions, thereby rotating the correction ball screw, and the first correction ball screw nut (208) and the second correction ball screw nut (218) move forward and backward simultaneously. The first correction ball screw nut (208) and the second correction ball screw nut (218) are positioned diagonally symmetrically with respect to an imaginary centerline in the longitudinal direction between the left and right side ends of the main support frame (110), so that the first cutting The support bracket (122), the first cutting connection bracket (124), the first upper cutting support bracket (167), the second cutting support bracket (132), the second cutting connection bracket (134), and the second upper cutting support bracket (177) are simultaneously rotated horizontally in a direction intersecting the electrode plate transfer line with respect to the first center hinge (208FCH) and the second center hinge (208SCH), and in this state, the first upper cutter (125) and the second upper cutter (135) are simultaneously lowered toward the first lower cutter (126) and the second lower cutter (136) so that the electrode plates on both sides can be cut while correcting the feeding position misalignment.

[0129] Therefore, the present invention has the effect of preventing cutting defects of the electrode plate by immediately correcting the feeding position misalignment of the electrode plate and cutting the electrode plate even if a feeding position misalignment phenomenon is about to occur during electrode plate transport. In other words, the present invention can be expected to have the effect of preventing cutting defects of the electrode plate by controlling the electrode plate right-angle defect. In other words, the present invention applies a servo, that is, by applying the first correction drive motor (202) and the second correction drive motor (212) as servo motors, so that the electrode plate cutting position is automatically adjusted during electrode plate feeding, thereby performing the function of controlling electrode plate right-angle defects.

[0130] In the present invention, feeding correction means that when cutting the electrode plate by the first upper cutter (125), the first lower cutter (126), the second upper cutter (135), and the second lower cutter (136), the electrode plate cutting positions of the first upper cutter (125) and the second upper cutter (135) are aligned so that the two side ends of the electrode plate are properly cut in a direction perpendicular to the front and rear ends of the electrode plate.

[0131] In addition, the present invention allows the electrode plate to be cut by being transported along the transport line of the main support frame (110) by means of a conveyor belt (152) made of a suction belt and a transport roller (140), thereby enabling the effect of more effectively preventing the feeding position misalignment of the electrode plate.

[0132] In addition, the present invention has a suction pipe (146) positioned below the transfer roller (140) and has a plurality of pipe-side suction holes formed on the outer surface extending away from the transfer roller (140), so that the electrode plate is transferred while adsorbing it with appropriate force by the suction pressure acting in the plurality of pipe-side suction holes, thereby having the effect of more reliably preventing the phenomenon of the electrode plate feeding position shifting.

[0133] Additionally, referring to FIGS. 22, 26, and 27, the present invention has the effect of stable stripping with a small stroke and prevention of noise and vibration by applying a stripper (180) separately from the cutter drive unit.

[0134] Additionally, referring to FIGS. 26 and 27, the present invention is equipped with two types of cams—one for cutter driving and one for stripper driving—on a single drive shaft (servo) so that the cutter and stripper are driven with different strokes, and the cam rotates to operate a lever, and the stripper lowering structure is connected to the lever by a rod end bearing. In the present invention, for example, a stripper stroke of 4 mm is applied.

[0135] In other words, a stripper (180) is mounted so as to be vertically movable on the main support frame (110), and is configured so that the stripper is vertically movable when the first upper cutting support bracket (167) and the first upper cutter (125) are vertically movable.

[0136] In this way, the stripper (180) is applied separately from the cutter drive unit, so that stable stripping with a small stroke and noise and vibration prevention effects are achieved.

[0137] In addition, in the present invention, a plurality of transfer rollers (140) and a transfer conveyor belt (152) are arranged on the electrode plate transfer line of the main support frame (110), so that the electrode plate is guided to be transferred by the plurality of transfer rollers (140) and the transfer conveyor, so that the cutting operation of both sides of the electrode plate by the dual cutter, that is, the first cutting unit (120) and the second cutting unit (130), is performed more smoothly.

[0138] In addition, by driving the transfer roller up-down drive motor (140UDM) provided on the main support frame (110), the transfer roller up-down cam (140UDC) rotates, causing the surf transfer roller support frame (140RSF) to be raised and lowered, thereby adjusting the gap between the transfer roller (140) and the transfer conveyor belt (152), so that the electrode plate can be smoothly transported in accordance with the thickness of the electrode plate.

[0139] In addition, the multiple tension rollers (144) provided on the transfer roller support frame (140RSF) move forward or backward toward the transfer conveyor belt (152) by means of an unillustrated forward / backward operating means (e.g., a forward / backward operating cylinder, etc.) to adjust the tension (tension) of the transfer conveyor belt (152), thereby having the effect of enabling the transfer of the electrode plate more smoothly in accordance with the thickness of the electrode plate.

[0140] In addition, as shown in FIG. 35, the present invention further provides a suction guide block (140SGBL) on the electrode plate transfer line of the main support frame (110), and the suction guide block (140SGBL) is provided with a suction chamber connected to a suction device not shown and a suction guide side suction hole, so that the electrode plate is suctioned by the suction guide block (140SGBL) with an appropriate suction pressure and guided to be transferred along the electrode plate transfer line of the main support frame (110), thereby increasing the transfer precision of the electrode plate.

[0141] In addition, by ensuring a height difference (e.g., a height difference of 0.2 to 0.3 mm) that is relatively higher than the height of the conveyor belt (152), which is the main part of the conveyor, compared to the height of the suction guide block (140SGBL), there is an effect of allowing the electrode plate being transported along the transport line of the main support frame (110) to be transported more smoothly without getting stuck.

[0142] Additionally, in the present invention, the cylinder rod of the first cutting contact cylinder (233) presses the first cutting support bracket (122) downward to rotate the first cutting support bracket (122) toward the first lower cutter (126) relative to the first horizontal hinge (123) connected to the main support frame (110), so that the first upper cutter (125) is in close contact with the first lower cutter (126), and at the same time, the cylinder rod of the second cutting contact cylinder (233) pushes the second cutting support bracket (132) in a horizontal direction to rotate the second cutting support bracket (132) so that it is pushed relative to the second horizontal hinge (133) connected to the main support frame (110), so that the second upper cutter (135) is in close contact with the second lower cutter (136), and in this state, the electrode plate Since dual cutting is performed to cut both sides simultaneously, it has the effect of enabling more accurate dual cutting operations on both sides of the electrode plate. That is, the present invention is characterized by being designed so that the center hinge position, which is the rotation axis, is the same as the electrode plate cutting position (the position where the first upper cutter (125) and the first lower cutter (126) and the second upper cutter (135) and the second lower cutter (136) come into contact), thereby allowing for more accurate adjustment.

[0143] Additionally, referring to FIG. 19, in the present invention, the stripper (180), the stripper-side LM guide (SLM), and the rod end bearing (REB) are applied so that the stripper operation is performed by the LM GUIDE applied to the side of the cutter, thereby having the effect of making the stripper operation of the stripper (180) precise and smooth.

[0144] Additionally, referring to FIG. 25, the present invention utilizes a cam-side LM guide (CLM), a cam push device (CMP), a spring (SP), a lever (i.e., a pair of first levers (165) and a pair of second levers (175)), and a rod end bearing (REB) (i.e., a rod end bearing (REB) provided at the upper and lower ends of a pair of first lifting operating rods (166) and second lifting operating rods (176)) so that lever operation is performed by the cam-side LM guide (CLM) and the cam push device, and since the stroke and position can be adjusted by adjusting the spring and the rod end bearing, the dual cutting precision of both sides of the electrode plate by the first cutting unit (120) and the second cutting unit (130) can be easily adjusted.
