Description

[0001] Case Analysis

[0002] This invention is a divisional application filed on April 3, 2019, with application number 201910264844X, entitled "Energy Storage Plate Cutter Position Calibration Device and Calibration Method Thereof". Technical Field

[0003] This invention relates to the field of battery plate slicing, and particularly to a calibration method for a plate slicing machine using a plate cutting blade position calibration device. Background Technology

[0004] In the manufacturing process of battery plates, the plates connected in pairs need to be cut into pieces by a plate cutting device. The structure of the piece-slicing machine is as follows: Figure 1 As shown, three cutters 10 are evenly spaced on a positioning shaft 11, which is rotatably connected to the frame. Each cutter 10 is clamped and positioned on both sides by sleeves 12 fitted onto the positioning shaft 11. The sleeves 12 at both ends are then threadedly locked to the positioning shaft 11 by locking nuts 13. Conveyor tracks 14 for transporting the electrode plates 8 to be cut are provided at both ends of the positioning shaft 11. Support plates 15 for placing auxiliary hanging ears 9 on both sides of the electrode plates 8 to be cut are also provided on the inner sides of the conveyor tracks 14. A conveyor belt 16 for transporting the slit electrode plates is also provided between pairs of cutters 10 and above the positioning shaft 11. During cutting, the electrode plates 8 to be cut (such as...) are first placed... Figure 2 The auxiliary hanging ears 9 on both sides are placed on the tray 15 (at this time, the electrode plate 8 to be cut will also be above the conveyor belt 16). Then, the conveyor rails 14, the transmission belt 16 and the positioning shaft 11 on both sides are started simultaneously. The conveyor rails 14 on both sides convey the electrode plate 8 to be cut to each cutter 10 through the trays 15 on both sides. The cutter 10 follows the positioning shaft 11 and rotates at high speed to cut the electrode plate 8 into pieces at the preset position. The pieced electrode plate falls onto the conveyor belt 16 and is transferred to the next process.

[0005] For electrode plates 8 of different sizes to be cut, the spacing between the two cutting blades 10 needs to be readjusted before each start-up. After adjustment, the electrode plates are then test-cut to determine whether the cutting dimensions meet the requirements. Since the electrode plates themselves will have slight deformation during the production process, adjusting the position of the cutting blades 10 based on the electrode plates will cause cumulative errors. As a result, it is difficult to improve the electrode plate slicing qualification rate. Moreover, test-cutting the electrode plates results in cost waste. Adjusting the cutting blades 10 is not only time-consuming and labor-intensive, but also has poor accuracy. Summary of the Invention

[0006] Purpose of the invention: To address the problems existing in the prior art, the present invention provides a calibration method for a slitting machine using an energy storage electrode plate cutting blade position calibration device. This calibration device can pre-calibrate the cutting blade spacing of the slitting machine according to the size of the electrode plate to be cut, ensuring the accuracy of the electrode plate cutting size, avoiding the occurrence of cumulative errors, improving the electrode plate slitting qualification rate, and reducing the cutting cost.

[0007] Technical solution: The present invention provides a device for calibrating the position of an energy storage plate cutter. Three positioning blocks are equally spaced on a positioning screw. Each positioning block is fixed to the positioning screw by adjusting nuts on both sides. Each positioning block has a positioning groove perpendicular to the positioning screw, and all positioning grooves are located on the same side of the positioning screw. Side positioning heads are installed at both ends of the positioning screw.

[0008] Furthermore, a positioning clip is fitted between each of the positioning blocks and each of the adjusting nuts. The positioning clip allows the adjusting nut to more effectively fix the positioning block to the positioning screw.

[0009] Furthermore, each of the side positioning heads has an internal adjusting thread, and each of the side positioning heads is threadedly connected to both ends of the positioning screw through the internal adjusting thread. The internal adjusting thread allows for adjustment of the distance between the ends of the two side positioning heads, enabling calibration of the distance between the auxiliary lugs on both sides of the electrode plate to be cut and the two conveyor tracks during the calibration of the slitting machine. This results in a more comprehensive calibration function and higher accuracy.

[0010] Furthermore, a scale of equivalent length is fixed to the positioning screw, and the scale and each positioning groove are located on both sides of the positioning screw. The scale makes it easier to adjust the adjusting nut by referring to the scale when adjusting according to the size of the electrode plate to be cut.

[0011] This invention also provides a calibration method for a slitting machine using an energy storage electrode plate cutter position calibration device, characterized by the following steps: S1: Adjusting the spacing between each positioning block by rotating the adjusting nut according to the size of the electrode plate to be cut, so that the spacing between the positioning slots of each positioning block is equal to the width of the electrode plate after slitting; S2: Adjusting the spacing between the ends of the side positioning heads at both ends by rotating the side positioning head, so that the spacing between the ends of the side positioning heads at both ends is equal to the spacing between the ends of the auxiliary lugs on both sides of the electrode plate to be cut; S3: Inserting each cutter on the slitting machine into each of the three positioning slots, and observing whether the spacing between any two cutters is equal to the spacing between any two positioning slots; if not, replacing with a correctly sized clamp; if equal, the clamp size is correct. This calibration device can be used to detect the spacing between any two cutters of the slitting machine.

[0012] Further, following S3, the following step is included: S4: While keeping each cutter still within its respective positioning groove, place the side positioning heads at both ends onto the inner sides of the two conveyor tracks of the slicer. Observe whether the distance between the inner sides of the two conveyor tracks is equal to the distance between the ends of the side positioning heads. If they are not equal, adjust the distance between the two conveyor tracks until they are equal. At this point, the calibration is complete, and the calibration device can be removed. If they are equal, it indicates that the distance between the two conveyor tracks is accurate. After the calibration device detects that the distance between the cutters is inaccurate, it is necessary to replace the clamp with one of the correct size. After replacing the clamp, the calibration device can still be used to calibrate and adjust the distance between the two conveyor tracks of the slicer.

[0013] Working principle and beneficial effects: When calibrating the slitting machine, firstly, according to the size of the electrode plate to be cut, adjust the spacing between each positioning block by rotating the adjusting nut so that the spacing between the positioning slots of each positioning block is equal to the width of the electrode plate after slitting. Then, adjust the spacing between the ends of the side positioning heads by rotating the side positioning heads so that the spacing between the ends of the side positioning heads is equal to the spacing between the ends of the auxiliary hanging ears on both sides of the electrode plate to be cut. Then, insert the three cutters on the slitting machine into the three positioning slots on the three positioning blocks of this calibration device, and observe whether the spacing between each pair of cutters is equal to the spacing between each pair of cutters. If the spacing between the positioning slots is equal, it indicates that the clamping sleeves between the two pairs of cutters are of incorrect size. Replace them with clamps of the correct size and tighten them with lock nuts. If the spacing is equal, it indicates that the clamping sleeves between the two pairs of cutters are of correct size. Then, while keeping each cutter in its respective positioning slot, place the positioning heads at both ends of this device onto the two inner trays on the two sides of the conveyor rails of the slicer. Observe whether the spacing between the inner sides of the two conveyor rails is equal to the spacing between the ends of the positioning heads. If they are not equal, adjust the spacing between the two conveyor rails until they are equal. The calibration is now complete. After removing this calibration device, the slicer can be started for slice operation.

[0014] As can be seen, after calibrating the slitting machine using this device, the spacing between the two cutting blades of the slitting machine is more precise, and there will be no cumulative error caused by the slight deformation of the test cutting plate itself, which greatly improves the plate slitting qualification rate, reduces the test cutting cost, and the calibration accuracy is accurate; it can also calibrate the spacing between the two conveyor tracks of the slitting machine.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] This embodiment provides a device for calibrating the position of an energy storage plate cutter, as shown in Figure 3. It mainly consists of three positioning blocks 1, positioning screws 2, six adjusting nuts 3, six positioning clamps 6, two side positioning heads 5, and a scale 7. The three positioning blocks 1 are evenly spaced on the positioning screws 2. A positioning clamp 6 is fitted on each side of each positioning block 1. Two adjusting nuts 3 are threaded onto the positioning screws 2 on both sides of the positioning clamps 6, clamping and fixing the two positioning clamps 6 and the positioning blocks 1. Each positioning block 1 has a positioning groove 4 perpendicular to the positioning screw 2, and all positioning grooves 4 are located on the same side of the positioning screw 2. A side positioning head 5 with an internal adjusting thread is threaded onto both ends of the positioning screw 2. A scale 7 of similar length is fixed to one end of the positioning screw 2, and the scale 7 and each positioning groove 4 are located on opposite sides of the positioning screw 2.

[0022] When calibrating the slitting machine using this device, first, according to the size of the electrode plate 8 to be cut, adjust the spacing between each positioning block 1 by rotating the adjusting nut 3 and comparing it with the scale 7, so that the spacing between the positioning grooves 4 of each positioning block 1 is equal to the width of the electrode plate after slitting; adjust the spacing between the ends of the side positioning heads 5 by rotating the side positioning heads 5 and comparing it with the scale 7, so that the spacing between the ends of the side positioning heads 5 at both ends is equal to the spacing between the ends of the auxiliary hanging ears 9 on both sides of the electrode plate 8 to be cut; then, insert the three cutters 10 on the slitting machine into the three positioning grooves 4 on the three positioning blocks 1 of this calibration device, and observe whether the spacing between any two pairs of cutters 10 is equal to the spacing between any two pairs of positioning grooves 4. If they are not equal, it means that the size of the clamping sleeve 12 between any two pairs of cutters 10 is incorrect. Replace it with a clamping sleeve 12 of the correct size and then tighten it with the locking nut 13; if they are equal, it means that the size of the clamping sleeve 12 between any two pairs of cutters 10 is correct. Then, as... Figure 4While keeping each cutter 10 within its respective positioning slot 4, place the two end positioning heads 5 of this device onto the two inner trays 15 on opposite sides of the two side conveyor tracks 14 of the slicer. Observe whether the distance between the inner sides of the two side conveyor tracks 14 is equal to the distance between the ends of the two end positioning heads 5. If they are not equal, adjust the distance between the two side conveyor tracks 14 until they are equal. At this point, the calibration is complete. Then remove this calibration device. Figure 5 Once the electrode plate 8 to be cut is placed on the conveyor track 14, the slitting machine can be started to perform the slitting operation.
