Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and in particular to a parallelism detection device and a parallelism detection system for a lithium battery die-cutting machine. Background Art

[0002] In the process of lithium battery production, the battery electrodes need to be die-cut to divide the larger battery electrodes into units of different sizes so that they can be subsequently processed into battery cells of different specifications to adapt to the production of batteries of different specifications.

[0003] At present, in the actual production process of lithium batteries, due to the thin thickness of the battery electrodes, in order to enable the die-cutting machine to quickly and smoothly die-cut the battery electrodes to be cut, the gap between the upper and lower plates of the die-cutting machine is set to be smaller, so that the smaller gap can better adapt to the thinner thickness of the battery electrodes to be cut. After adjusting the gap between the upper and lower plates of the die-cutting machine, it is also necessary to perform a parallelism test on the gap between the upper and lower plates of the die-cutting machine. In this way, it can be ensured that the die-cutting machine can quickly and smoothly die-cut the battery electrodes to be cut, so as to obtain battery electrodes with high incision flatness and no powder falling.

[0004] However, since the gap between the upper and lower plates of the die-cutting machine is set to be small, this will increase the difficulty of detecting the parallelism of the gap between the upper and lower plates of the die-cutting machine, making it difficult for a general detection micrometer to enter the upper and lower plates with a smaller gap for detection operations. Only a hand-cranked lever-type internal diameter micrometer can be used for detection. However, the measurement error of the hand-cranked lever-type internal diameter micrometer is large, and thus the accuracy of the parallelism of the gap between the upper and lower plates of the die-cutting machine cannot be guaranteed, and thus battery electrodes with high incision flatness and no powder loss cannot be obtained.

[0037] The present application provides a parallelism detection device, comprising a mounting seat and a measuring assembly, wherein the measuring assembly comprises a horizontal conversion height measuring piece and a detection micrometer, wherein the detection micrometer is horizontally arranged on the mounting seat, the horizontal conversion height measuring piece is rotatably arranged on the mounting seat, and the horizontal conversion height measuring piece swings and abuts against the detection micrometer, and the horizontal conversion height measuring piece is used to convert vertical measurement into horizontal measurement during measurement.

[0038] The above-mentioned parallelism detection device, by horizontally setting the detection micrometer on the mounting seat, so that the extension direction of the detection micrometer can be parallel to the horizontal plane where the mounting seat is located. Since the horizontal conversion height measuring part is rotatably set on the mounting seat, when the horizontal conversion height measuring part contacts the upper plate of the die-cutting machine, the horizontal conversion height measuring part is blocked by the upper plate, so that the horizontal conversion height measuring part can swing in the direction close to the detection micrometer and abut against the detection micrometer, so that the horizontal conversion height measuring part can form a detection path with the detection micrometer, so as to realize accurate measurement of the parallelism of the gap between the upper and lower plates of the die-cutting machine, thereby realizing that the horizontal conversion height measuring part can rotate the vertical measurement into the horizontal measurement during measurement. In this way, not only the accuracy of the detection result of the parallelism detection device is improved, and the phenomenon of large parallelism measurement error between the upper and lower plates of the die-cutting machine caused by large measurement error of the hand-cranked lever internal diameter micrometer is effectively avoided, but also when the horizontal conversion height measuring piece and the detection micrometer are swung and abutted, a Z-shaped connection structure can be formed with the detection micrometer, thereby effectively reducing the height of the parallelism detection device in the vertical direction Y, so that the parallelism detection device is thinner in thickness, so that the parallelism detection device can be well extended to the die-cutting machine with a smaller gap to perform accurate parallelism detection, thereby ensuring the accuracy of the detection result of the parallelism detection device, and effectively avoiding the phenomenon of large measurement error of the hand-cranked lever internal diameter micrometer causing die-cutting The parallelism measurement error between the upper and lower plates of the machine is large, and the measuring distance of the measuring component in the horizontal direction X is extended, so that users can measure some measurement points that are difficult for users to approach. For example, for some large die-cutting machines, when the middle of the upper and lower plates of the die-cutting machine need to be measured for parallelism, the user can easily detect the parallelism of the middle of the upper and lower plates of the die-cutting machine, that is, under the condition of ensuring that the parallelism detection device has high accuracy, the adaptability of the parallelism detection device to the gap detection of different die-cutting machines is also improved, and it is ensured that the battery pole piece with high incision flatness and no powder loss can be obtained after die-cutting, that is, a battery pole piece with good quality is obtained, which is especially suitable for the parallelism detection of super-large die-cutting machines with small gaps. Further, by rotating the horizontal conversion height measuring piece on the mounting seat, the user can quickly and smoothly put the horizontal conversion height measuring piece into the gap of the die-cutting machine, effectively avoiding the phenomenon of easy jamming during the measurement process, and effectively reducing the wear between the horizontal conversion height measuring piece and the measuring point, thereby extending the service life of the horizontal conversion height measuring piece.

[0039] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0040] See also Figures 1 to 3A parallelism detection device 10 in one embodiment includes a mounting seat 100 and a measuring assembly 200, wherein the measuring assembly 200 includes a horizontal conversion height measuring member 210 and a detection micrometer 220, wherein the detection micrometer 220 is horizontally arranged on the mounting seat 100, and the horizontal conversion height measuring member 210 is rotatably arranged on the mounting seat 100, and the horizontal conversion height measuring member 210 swings and abuts against the detection micrometer 220, and the horizontal conversion height measuring member 210 is used to convert vertical measurement into horizontal measurement during measurement.

[0041] The above-mentioned parallelism detection device 10, by horizontally setting the detection micrometer 220 on the mounting seat 100, so that the extension direction of the detection micrometer 220 can be parallel to the horizontal plane where the mounting seat 100 is located. Since the horizontal conversion height measuring part 210 is rotatably set on the mounting seat 100, when the horizontal conversion height measuring part 210 contacts the upper plate of the die-cutting machine 21, the horizontal conversion height measuring part 210 is blocked by the upper plate, so that the horizontal conversion height measuring part 210 can swing in the direction close to the detection micrometer 220 and abut against the detection micrometer 220, so that the horizontal conversion height measuring part 210 can form a detection passage with the detection micrometer 220, so as to realize accurate measurement of the parallelism of the gap between the upper and lower plates of the die-cutting machine 21, thereby realizing that the horizontal conversion height measuring part 210 can rotate the vertical measurement into the horizontal measurement during measurement. In this way, not only the accuracy of the detection result of the parallelism detection device 10 is improved, and the phenomenon that the measurement error of the hand-cranked lever-type internal diameter micrometer 222 is large, causing the parallelism measurement error between the upper and lower plates of the die-cutting machine 21 is large, but also when the horizontal conversion height measuring piece 210 and the detection micrometer 220 are swung and abutted, a Z-shaped connection structure can be formed with the detection micrometer 220, thereby effectively reducing the height of the parallelism detection device 10 in the vertical direction Y, so that the parallelism detection device 10 is thinner in thickness, so that the parallelism detection device 10 can be well extended to the die-cutting machine 21 with a smaller gap to perform accurate parallelism detection, thereby ensuring the accuracy of the detection result of the parallelism detection device 10, and effectively avoiding the measurement error of the hand-cranked lever-type internal diameter micrometer 222. The phenomenon of large parallelism measurement error between the upper and lower plates of the die-cutting machine 21 is caused, and the measuring distance of the measuring component 200 in the horizontal direction X is extended, so that users can measure some measuring points that are difficult for users to approach. For example, for some large die-cutting machines 21, when it is necessary to measure the parallelism of the middle parts of the upper and lower plates of the die-cutting machine 21, the user can easily detect the parallelism of the middle parts of the upper and lower plates of the die-cutting machine 21, that is, under the condition of ensuring that the parallelism detection device 10 has high accuracy, the adaptability of the parallelism detection device 10 to the gap detection of different die-cutting machines 21 is also improved, and it is ensured that after die-cutting, a battery electrode with high incision flatness and no powder falling can be obtained, that is, a battery electrode with better quality is obtained, which is particularly suitable for the detection of the parallelism of super-large die-cutting machines 21 with small gaps.

[0042] Furthermore, by rotating the horizontal conversion height measuring piece 210 on the mounting seat 100, the user can place the horizontal conversion height measuring piece 210 into the gap of the die-cutting machine 21 more quickly and smoothly, thereby effectively avoiding the phenomenon of jamming that is prone to occur during the measurement process, and effectively reducing the wear between the horizontal conversion height measuring piece 210 and the measuring point, thereby extending the service life of the horizontal conversion height measuring piece 210.

[0043] It should be noted that, compared with the traditional detection micrometer 220, when detecting the parallelism of the die-cutting machine 21, since a vertical measurement method is adopted, that is, the detection micrometer 220 is placed vertically on the mounting base 100, the height of the measuring part of the traditional detection micrometer 220 is at least 100 mm, and the die-cutting distance of the battery pole piece of the lithium battery is usually 50 mm, so that the measuring part of the traditional micrometer 222 is much higher than the gap between the upper and lower plates of the die-cutting machine 21, and thus the parallelism of the smaller gap between the upper and lower plates of the die-cutting machine 21 cannot be well detected. Therefore, the present invention sets the detection micrometer 220 horizontally on the mounting base 100 and connects it to the L-shaped horizontal conversion height measuring piece 210. In this way, the distance of the parallelism detection device 10 in the vertical direction Y can be effectively shortened, and the distance of the parallelism detection device 10 in the horizontal direction X can be extended, so that the parallelism detection device 10 can detect the parallelism of the die-cutting machine 21 with a smaller gap of less than 50 mm, which is particularly suitable for the detection of the parallelism of super-large die-cutting machines 21 with smaller gaps.

[0044] like Figure 1 , Figure 3 As shown, in one embodiment, the horizontal conversion height measuring member 210 includes a connecting frame 211 and a measuring contact member 212, the connecting frame 211 is rotatably set on the mounting base 100, and the connecting frame 211 swings and abuts against the detection micrometer 220, the connecting frame 211 is provided with a horizontal detection surface 213, the measuring contact member 212 is arranged on the horizontal detection surface 213, and the horizontal detection surface 213 is used for the connecting frame 211 to remain parallel to the horizontal plane where the mounting base 100 is located when the connecting frame 211 swings and abuts against the detection micrometer 220. It can be understood that by providing a horizontal detection surface 213 on the connecting frame 211, and the horizontal detection surface 213 is provided with a measuring contact piece 212, when the measuring contact piece 212 contacts the measuring point, the connecting frame 211 is blocked by the upper plate of the die-cutting machine 21, so that the connecting frame 211 will rotate, so that the connecting frame 211 can move toward one end close to the detection micrometer 220, so that the connecting frame 211 can abut against the detection micrometer 220, and when the connecting frame 211 abuts against the detection micrometer 220, a detection passage is formed with the detection micrometer 220, and the horizontal detection surface 213 of the connecting frame 211 can remain parallel to the horizontal plane where the mounting seat 100 is located, so as to ensure the accuracy of the parallelism detection of the parallelism detection device 10, and enable the horizontal conversion height measuring piece 210 to convert the vertical measurement into the horizontal measurement.

[0045] In one embodiment, the height of the connecting frame 211 on the mounting seat 100 is not higher than the height of the mounting seat 100 itself. It can be understood that if the height of the connecting frame 211 on the mounting seat 100 is higher than the height of the mounting seat 100 itself, the measuring height of the horizontal conversion height measuring piece 210 in the vertical direction Y of the parallelism detection device 10 will be increased, so that the parallelism detection device 10 cannot adapt to the parallelism detection of the die-cutting machine 21 with a smaller gap. Therefore, the present invention makes the height of the connecting frame 211 on the mounting seat 100 not higher than the height of the mounting seat 100 itself, so that the height of the horizontal conversion height measuring piece 210 in the vertical direction Y of the parallelism detection device 10 can maintain a relatively small measuring height, so that the parallelism detection device 10 can be well extended into the die-cutting machine 21 with a smaller gap for parallelism detection, thereby improving the adaptability to the die-cutting machine 21 with a smaller gap.

[0046] like Figure 3 , Figure 4 As shown, in one embodiment, the connecting frame 211 includes a horizontal connecting member 2111 and a vertical conversion connecting member 2112, and the horizontal connecting member 2111 and the vertical conversion connecting member 2112 are connected at an angle so that the connecting frame 211 has two degrees of freedom in the vertical direction and the horizontal direction, and a rotation matching portion 2113 is provided at the angle connection, and the mounting seat 100 is provided with a rotating portion 110, and the rotating portion 110 is rotatably provided on the rotating matching portion 2113 to realize the rotation connection between the connecting frame 211 and the mounting seat 100, so that the connecting frame 211 can convert the vertical direction measurement into the horizontal direction measurement, and the horizontal direction measurement is rotatable. The flat connecting piece 2111 is provided with the horizontal detection surface 213, and the extension direction of the horizontal connecting piece 2111 is parallel to the horizontal plane where the mounting seat 100 is located, so as to ensure that the horizontal detection surface 213 can remain relatively parallel to the horizontal plane where the mounting seat 100 is located, so as to ensure that when the parallelism detection device 10 is measuring, the horizontal detection surface 213 and the detection micrometer 220 can be parallel to the horizontal plane where the mounting seat 100 is located, thereby ensuring the accuracy of the detection result of the parallelism detection device 10, and the vertical conversion connecting piece 2112 swings and abuts against the detection micrometer 220 to realize the conversion of the connection frame 211 in the two degrees of freedom measurement in the vertical direction and the horizontal direction.

[0047] like Figure 3 , Figure 4As shown, in this embodiment, the rotating portion 110 is provided with a rotating groove 111, a rotating rod 112 is arranged in the rotating groove 111, and the rotating matching portion 2113 is provided with a rotating hole 2113a, and the rotating rod 112 is rotatably arranged in the rotating hole 2113a, so as to realize the rotating setting of the rotating portion 110 and the rotating matching portion 2113. Of course, the rotating setting of the rotating portion 110 and the rotating matching portion 2113 is not limited to the above-mentioned connection method. In other embodiments, the rotating portion 110 and the rotating matching portion 2113 can also be realized by providing a rotating hole 2113a in the rotating portion 110 and providing the rotating rod 112 in the rotating matching portion 2113.

[0048] It should be noted that, by providing a rotation groove 111 in the rotating portion 110 of the mounting seat 100, the rotation groove 111 can provide a larger space for the connection frame 211 to rotate, so that the connection frame 211 can rotate more flexibly in the rotation groove 111, so that the user can smoothly and quickly put the horizontal conversion height measuring piece 210 into the gap between the upper and lower plates of the die-cutting machine 21 for parallelism detection. Furthermore, since the rotation groove 111 can accommodate part of the connection frame 211 in the rotation groove 111, it is effectively avoided that the connection frame 211 is completely exposed on one side of the mounting seat 100, which not only improves the compactness of the connection structure between the horizontal conversion height measuring piece 210 and the mounting seat 100, but also effectively reduces the measurement height of the horizontal conversion height measuring piece 210 in the vertical direction Y of the parallelism detection device structure, thereby realizing the detection of the parallelism of the die-cutting machine 21 with a smaller gap. Furthermore, the mounting base 100 is provided with a rotating portion 110, and the rotating portion 110 is protrudingly arranged on the mounting base 100. On the one hand, the rotating portion 110 is protrudingly arranged on the mounting base 100, which can extend the measuring distance of the mounting base 100 in the horizontal direction X to better adapt to some measuring points that are difficult for users to reach; on the other hand, the rotating portion 110 can provide better rotational support for the connecting frame 211, so that the connecting frame 211 can rotate well on the rotating portion 110, and can also extend the measuring distance of the parallel detection device structure in the horizontal direction X.

[0049] In one embodiment, the center point of the rotating hole 2113a overlaps with the center point of the angle connection, so that the connecting frame 211 can rotate about the center axis of the angle connection, so that the connecting frame 211 can swing more smoothly on the mounting base 100.

[0050] In one embodiment, a rotation avoidance portion is formed at the angle connection, so that the connecting frame 211 can rotate smoothly in the rotation groove 111 without being stuck.

[0051] In one embodiment, the width of the rotating groove 111 is smaller than the length of the horizontal connecting member 2111. It can be understood that if the width of the rotating groove 111 is greater than the length of the horizontal connecting member 2111, when the user uses the parallelism detection device 10 to measure the gap of the die-cutting machine 21, the connecting frame 211 is blocked by the measuring point and rotates. Since the width of the rotating groove 111 is greater than the length of the horizontal connecting member 2111, the connecting frame 211 can rotate 360 ​​degrees around the rotating rod 112, thereby making it impossible for the vertical conversion connecting member 2112 to swing and connect with the detection dial gauge 220, that is, the vertical conversion connecting member 2112 cannot form a detection path with the detection dial gauge 220. Therefore, the present invention sets the width of the rotating groove 111 to be smaller than the length of the horizontal connecting piece 2111, so that the connecting frame 211 can rotate more smoothly in the rotating groove 111 and is not prone to jamming, so that the user can quickly perform parallelism detection on the gap between the upper and lower plates of the die-cutting machine 21, and can also effectively ensure that the vertical conversion connecting piece 2112 and the detection micrometer 220 form a detection passage to ensure the normal operation of the detection, and the rotating groove 111 can also accommodate most of the connecting frame 211 in the rotating groove 111, so as to effectively shorten the measurement distance of the horizontal conversion height measuring piece 210 in the vertical direction Y of the parallelism detection device 10, so as to ensure that the measurement height of the measuring component 200 in the vertical direction of the parallelism detection device 10 is smaller, thereby improving the adaptability of the parallelism detection device 10 to the detection of the parallelism of the die-cutting machine 21 with a smaller gap.

[0052] In other embodiments, the rotating rod 112 is detachably connected to the side wall of the rotating groove 111, so that the user can disassemble and assemble the damaged horizontal conversion height measuring member 210 to increase the speed of maintenance. Further, in this embodiment, the side wall of the rotating groove 111 is correspondingly provided with a plug hole, and the rotating rod 112 is adapted to the plug hole, the rotating rod 112 passes through the rotating hole 2113a and the plug hole, and abuts against the side wall of the plug hole to achieve the rotating rod 112 and the side wall of the rotating groove 111, so that the user can quickly disassemble and assemble the damaged horizontal conversion height measuring member 210. Furthermore, the rotating rod 112 is a pin to achieve the detachable connection between the rotating rod 112 and the side wall of the rotating groove 111.

[0053] In one embodiment, the measuring contact member 212 is arranged on the end of the horizontal detection surface 213 away from the horizontal connecting member 2111, so that the measuring distance of the horizontal conversion height measuring member 210 in the horizontal direction X of the parallelism detection device 10 can be further increased, so that users can more easily measure some measuring points that are difficult for users to approach.

[0054] In one embodiment, the horizontal detection surface 213 is provided with a receiving cavity, and the measuring contact member 212 is arranged in the receiving cavity and at least partially protrudes from the receiving cavity. It can be understood that by providing a receiving cavity in the horizontal detection surface 213 so as to accommodate the measuring contact member 212 in the receiving cavity, it is possible to effectively avoid the measuring contact member 212 being completely exposed on the horizontal detection surface 213. In this way, on the one hand, the compactness of the overall structure of the horizontal conversion height measuring member 210 can be improved, and on the other hand, the height of the parallelism detection device 10 in the vertical direction Y can be effectively reduced to ensure that the distance of the parallelism detection device 10 in the vertical direction Y is short, so as to well adapt to the measurement of the parallelism of the die-cutting machine 21 with a small gap. In this embodiment, the measuring contact member 212 is arranged on one end of the horizontal detection surface 213 away from the vertical conversion connector 2112, thereby extending the measuring distance of the parallelism detection device 10 in the horizontal direction X, so as to better adapt to some measurement points that are far away and difficult for users to approach, thereby improving the adaptability of the parallelism detection device 10.

[0055] In one embodiment, the accommodating cavity is adapted to the measuring contact member 212, so that the measuring contact member 212 can be well accommodated and fixed in the accommodating cavity. Further, the measuring contact member 212 is a measuring steel ball 223. Since the measuring steel ball 223 has a good arc surface, the contact surface of the horizontal conversion height measuring member 210 when it is inserted into the upper and lower plates of the die-cutting machine 21 is relatively small, so as to reduce the wear between the measuring contact member 212 and the measuring point during measurement, and ensure that the user can smoothly place the parallelism detection device 10 in the gap between the upper and lower plates of the die-cutting machine 21.

[0056] In one embodiment, the angle is less than 180 degrees. It can be understood that by controlling the angle of connection between the horizontal connector 2111 and the vertical conversion connector 2112 to be less than 180 degrees, it is ensured that the horizontal conversion height measuring member 210 can have two degrees of freedom in the vertical direction Y and the horizontal direction X, so that when the connecting frame 211 and the mounting seat 100 rotate, the vertical conversion connector 2112 can swing and abut against the detection dial gauge 220, so that the horizontal conversion height measuring member 210 can convert vertical measurement into horizontal measurement during measurement.

[0057] like Figure 6As shown, in this embodiment, the angle is 90 degrees. It can be understood that by setting the angle between the horizontal connector 2111 and the vertical conversion connector 2112 to 90 degrees, the extension direction of the horizontal connector 2111 and the extension direction of the vertical conversion connector 2112 are perpendicular to each other to form an L-shaped connecting frame 211. It should be noted that since the connecting frame 211 is rotatably set on the mounting seat 100, it is difficult to ensure that the extension direction of the horizontal connector 2111 and the horizontal plane where the mounting seat 100 is located remain parallel to each other when the vertical conversion connector 2112 abuts against the detection dial gauge 220, thereby affecting the accuracy of the detection result. Therefore, the present invention sets the included angle to 90 degrees to ensure that when the vertical conversion connector 2112 abuts against the detection dial gauge 220, the extension direction of the horizontal connector 2111 can be perpendicular to the vertical conversion connector 2112. Since the extension direction of the horizontal connector 2111 is parallel to the horizontal plane where the mounting seat 100 is located, the horizontal detection surface 213 on the horizontal connector 2111 can be parallel to the horizontal plane where the mounting seat 100 is located when the parallelism detection device 10 is measuring, so as to ensure that a high-accuracy detection result is obtained, thereby improving the detection accuracy of the parallelism detection device 10. Furthermore, the included angle of 90 degrees, relative to other angles, such as 45 degrees and 120 degrees, makes the detection path formed by the measuring abutment, the horizontal connector 2111, the vertical conversion connector 2112 and the detection dial gauge 220 the shortest, thereby improving the detection speed of the detection dial gauge 220, so that the user can quickly and accurately detect the parallelism of the super-large die-cutting machine 21 with a small gap.

[0058] In this embodiment, the connecting frame 211 is an isosceles right triangle. It should be noted that, since the connecting frame 211 is an isosceles right triangle, the connecting frame 211 has good stability, and a rotation hole 2113a is provided at the angle connection, and the center point of the rotation hole 2113a overlaps with the center point of the angle connection, so that the extension direction of the rotation hole 2113a intersects with the diagonal line of the connecting frame 211 to form a 45-degree angle, so that the connecting frame 211 can swing around the center axis of the rotation hole 2113a stably and reliably. In other words, since the connecting frame 211 is an isosceles right triangle, the horizontal connecting piece 2111 and the length of the vertical conversion connecting piece 2112, and the measuring contact piece 212 is set at the farthest end of the horizontal connecting piece 2111 away from the vertical conversion connecting piece 2112. According to the lever principle, it can be known that: F1 power × L1 power arm = F2 resistance × L2 resistance arm, so it can be seen that the force F1 of the measuring contact piece 212 is the same as the force F2 of the measuring steel ball of the detection micrometer 220, thereby ensuring that the horizontal conversion height measuring piece 210 can accurately convert the vertical measurement into the horizontal measurement, thereby improving the accuracy of the detection result of the parallelism detection device 10.

[0059] like Figure 3 , Figure 5 As shown, in one embodiment, the parallelism detection device 10 also includes an adjusting locking piece 300, the mounting seat 100 includes a base 120 and a fixed seat 130, the fixed seat 130 is slidably arranged on the base 120, the detection micrometer 220 is horizontally plugged into the fixed seat 130, the connecting frame 211 is rotatably arranged on the fixed seat 130, and the fixed seat 130 is detachably connected to the base 120 via the adjusting locking piece 300. It can be understood that by sliding the fixing seat 130 on the mounting seat 100, and the fixing seat 130 is detachably connected to the base 120 through the adjusting locking member 300, when the user needs to adjust the measuring distance of the parallelism detection device 10, the adjusting locking member 300 can be first removed, and then the fixing seat 130 is manually moved to a suitable position, and then the adjusting locking member 300 is installed back on the fixing seat 130 and the base 120 to achieve the adjustment of different measuring heights of the parallelism detection device 10, so as to better adapt to the detection requirements of the die-cutting machine 21 with different gaps, thereby improving the adaptability of the parallelism detection device 10 to the parallelism detection of the die-cutting machine 21 with different gaps. In this embodiment, the adjusting locking member 300 is a bolt to achieve the detachable connection between the fixing seat 130 and the base 120.

[0060] like Figures 3 to 5 As shown, in one embodiment, the fixing seat 130 is formed with a through mounting hole 131, the extension direction of the mounting hole 131 is parallel to the horizontal plane where the base 120 is located, the detection micrometer 220 is inserted into the mounting hole 131 and at least partially protrudes from the mounting hole 131; the connecting frame 211 is swingably connected to the detection micrometer 220 protruding from the mounting hole 131.

[0061] It can be understood that by providing a through mounting hole 131 in the fixing seat 130, and the extension direction of the mounting hole 131 is parallel to the horizontal plane where the fixing seat 100 is located, so that the detection dial gauge 220 can be inserted into the mounting hole 131, that is, the detection dial gauge 220 is horizontally arranged on the fixing seat 100. Further, by inserting the detection dial gauge 220 into the mounting hole 131 and at least partially protruding from the mounting hole 131, so that the connecting frame 211 can be swung and connected to the detection dial gauge 220 protruding from the mounting hole 131, it is ensured that the connecting frame 211 can form a detection passage with the detection dial gauge 220 to ensure the normal detection, thereby realizing the detection dial gauge 220 is horizontally arranged on the fixing seat 130. In this embodiment, the fixing seat 130 is provided with the rotating part 110, and the rotating part 110 is protruding from the fixing seat 130 to extend the measuring distance of the horizontal direction X of the parallelism detection device 10.

[0062] like Figure 3 , Figure 5 As shown, in one embodiment, the fixed seat 130 is provided with a sliding groove 132 and a through hole 133 connected to the sliding groove 132, the mounting hole 131 and the sliding groove 132 are staggered, a sliding block 121 is provided on the base 120, the sliding block 121 is slidably set in the sliding groove 132, and the adjusting locking member 300 passes through the through hole 133 and abuts against the sliding block 121.

[0063] It can be understood that by providing the sliding groove 132 and the through hole 133 on the fixed seat 130, the through hole 133 allows the adjusting locking member 300 to pass through the through hole 133, so that the adjusting locking member 300 can install and lock the fixed seat 130 in a required position. At the same time, since the fixed seat 130 is provided with the sliding groove 132 and the base 120 is provided with a sliding block 121, the adjusting locking member 300 passes through the through hole 133 and abuts against the sliding block 121 to achieve a sliding connection between the fixed seat 130 and the base 120, and cooperates with the use of the adjusting locking member 300 to achieve the sliding block 121 to provide different adjustment positions for the measuring component 200, thereby achieving the adjustment of different measuring heights of the parallelism detection device 10 to better adapt to the detection requirements of the die-cutting machine 21 with different gaps, thereby improving the adaptability of the parallelism detection device 10 to the parallelism detection of the die-cutting machine 21 with different gaps. Furthermore, there are multiple through holes 133. Since the multiple through holes 133 can provide different locking positions for the adjustment locking member 300, the user can switch the adjustment locking member 300 to lock the through holes 133 at different positions, thereby increasing the user's way of adjusting the measuring position of the measuring component 200 on the fixed base 130, so as to better adapt to the detection of parallelism of different gap die-cutting machines 21.

[0064] like Figure 3As shown, in this embodiment, the detection digital micrometer 222 includes a detection main rod 221 and a digital micrometer 222 connected to each other. The detection main rod 221 passes through the mounting hole 131 and at least partially protrudes from the mounting hole 131. The detection main rod 221 is provided with a measuring steel ball 223, and the measuring steel ball 223 is used to movably abut against the vertical conversion connecting piece 2112. When the gap between the upper and lower plates of the die-cutting machine 21 is detected, the horizontal connecting piece 2111 is blocked by the measuring point and can rotate, so that the horizontal detection point of the horizontal connecting piece 2111 can be rotated. The measuring surface 213 is parallel to the horizontal plane where the base 120 is located to ensure the accuracy of the detection result. At the same time, the vertical conversion connecting piece 2112 can be movably abutted against the measuring steel ball 223 of the detection main rod 221. At this time, the measuring steel ball 223 of the detection main rod 221 can sense the measurement information and feed the measurement information back to the digital micrometer 222, so that the digital micrometer 222 can display it, that is, the horizontal conversion height measuring piece 210 can form a detection path with the detection micrometer 220, thereby realizing the detection of the parallelism of the gap between the upper and lower plates of the die-cutting machine 21.

[0065] Furthermore, if Figure 3 , Figure 5 As shown, in one embodiment, the parallelism detection device 10 further includes a height adjustment member 400, which is disposed on the fixing seat 130, and is used to adjust the fixing seat 130 in a vertical direction. It can be understood that by adding the height adjustment member 400 to the fixing seat 130, the user can change the measuring distance of the measuring component 200 in the vertical direction of the fixing seat 130 by adjusting the height of the height adjustment member 400 itself, thereby improving the adaptability of the parallelism detection device 10 to the parallelism detection of the die-cutting machines 21 with different gaps.

[0066] like Figure 3 , Figure 5 As shown, in one embodiment, the height adjustment member 400 includes an adjusting bolt 410 and a clamping member 420 connected to each other, the adjusting bolt 410 and the clamping member 420 are connected to form a clamping groove, the base 120 is provided with a corresponding threaded hole 122, the fixing seat 130 is provided with a clamping portion 134, and the clamping portion 134 is clamped in the clamping groove, the adjusting bolt 410 is passed through the threaded hole 122 and is screwed to the side wall of the threaded hole 122, so that the fixing seat 130 can be detachably connected to the mounting seat 100 through the height adjustment member 400, so that the user can adjust the measuring distance of the measuring component 200 in the vertical direction on the mounting seat 100, thereby improving the adaptability of the parallelism detection device 10 to the parallelism detection of the die-cutting machine 21 with different gaps.

[0067] like Figure 2 , Figure 3 As shown, in order to ensure that the measuring height of the detection micrometer 220 in the vertical direction Y of the parallelism detection device 10 is small, in one embodiment, the base 120 is provided with a through receiving groove 123, the receiving groove 123 is adapted to the detection micrometer 220, and the receiving groove 123 is used to accommodate the detection micrometer 220. It can be understood that if the detection micrometer 220 is directly mounted on the mounting seat 100, the height of the parallelism detection device 10 in the vertical direction Y will be further increased. Therefore, the present invention can effectively reduce the height of the parallelism detection device 10 itself in the vertical direction Y by providing a through receiving groove 123 on the mounting seat 100 so that the receiving groove 123 can accommodate most of the detection micrometer 220, so that the parallelism detection device can better adapt to the detection of the die-cutting machine 21 with a smaller gap, and also improve the compactness of the overall structure of the parallelism detection device 10. Furthermore, in order to better reduce the height of the parallelism detection device 10 itself in the vertical direction Y, the detection micrometer 220 is of smaller specifications to ensure that a thinner parallelism detection device 10 is obtained to better adapt to the detection of a die-cutting machine 21 with a smaller gap.

[0068] like Figure 2 and Figure 3 As shown, in one embodiment, the base 120 is provided with a receiving groove 124, so that the receiving groove 124 can accommodate a part of the fixing seat 130. It can be understood that the base 120 is provided with a receiving groove 124, and the sliding block 121 is arranged on the side wall of the receiving groove 124. In this way, on the one hand, the compactness of the connection structure between the base 120 and the fixing seat 130 is improved, and on the other hand, the height of the fixing seat 130 in the vertical direction Y on the base 120 can be effectively reduced, so that the parallelism detection device 10 can better adapt to the detection of the die-cutting machine 21 with a smaller gap. In other embodiments, the cross-section of the mounting seat 100 is stepped. Since the mounting seat 100 includes a connected fixing seat 130 and a base 120, and since the base 120 is provided with an accommodating groove 123 and an accommodating groove 124, the cross-section of the mounting seat 100 is stepped. In this way, not only the compactness of the structure of the parallelism detection device 10 is improved, but also the height of the parallelism detection device 10 itself in the vertical direction Y is maximized, so that the parallelism detection device can better adapt to the detection of the die-cutting machine 21 with a smaller gap, and the compactness of the overall structure of the parallelism detection device 10 is also improved.

[0069] like Figure 2 , Figure 3As shown, in one embodiment, the parallelism detection device 10 further includes a limit assembly 500, which is disposed on the mounting seat 100, and is used to limit and fix the horizontal conversion height measuring member 210. It can be understood that by adding the limit assembly 500 to the mounting seat 100, the limit assembly 500 can limit and fix the horizontal conversion height measuring member 210, so as to ensure that when the horizontal conversion height measuring member 210 is measuring, the vertical conversion connecting member 2112 can be well swung and abutted against the detection micrometer 220. In this embodiment, the limit assembly 500 is disposed on the base 120, and the limit assembly 500 is disposed on one side of the measuring assembly 200, so as to realize the limit and fixation of the vertical conversion connecting member 2112 by the limit assembly 500.

[0070] like Figure 3 As shown, in one embodiment, the limit assembly 500 includes a support seat 510 and a limit bolt 520, the support seat 510 is arranged on one side of the horizontal conversion height measuring member 210, and the support seat 510 is connected to the base 120, the support seat 510 is provided with a limit threaded hole 122, the limit bolt 520 passes through the limit threaded hole 122 and at least partially protrudes from the limit threaded hole 122, the limit bolt 520 is threadedly connected to the limit threaded hole 122, so that the horizontal conversion height measuring member 210 can only move in the distance between the limit bolt 520 and the measuring steel ball 223 on the detection main rod 221, thereby realizing the limit fixation of the vertical conversion connecting member 2112 by the limit bolt 520. In addition, since the limit bolt 520 is threadedly connected to the base 120, the user can change the spacing between the limit bolt 520 and the measuring steel ball 223 on the detection main rod 221 by adjusting the limit threaded hole 122 of the limit bolt 520, thereby realizing different limit requirements for the horizontal conversion height measuring part 210. Furthermore, since the limit bolt 520 is threadedly connected to the base 120, a detachable connection between the limit bolt 520 and the base 120 is realized, so that the user can disassemble and assemble the damaged limit bolt 520.

[0071] In one embodiment, the spacing between the limit bolt 520 and the measuring steel ball 223 on the detection main rod 221 is smaller than the length of the vertical conversion connector 2112. It can be understood that by setting the spacing between the limit bolt 520 and the measuring steel ball 223 on the detection main rod 221 to be smaller than the length of the vertical conversion connector 2112, the vertical conversion connector 2112 can be effectively restricted from rotating 360 degrees so that the vertical conversion connector 2112 cannot flexibly abut against the measuring steel ball 223 on the detection main rod 221, thereby causing the horizontal conversion height measuring member 210 to be unable to form a detection path with the measuring steel ball 223. By setting the spacing between the limit bolt 520 and the measuring steel ball 223 on the detection main rod 221 to be smaller than the length of the vertical conversion connector 2112, when the user performs parallelism detection on the gap of the die-cutting machine 21, the user places the parallelism detection device 10 in the gap of the die-cutting machine 21 without the occurrence of a jamming phenomenon, and the accuracy of the detection result of the parallelism detection device 10 is also ensured.

[0072] It should be noted that, in order to ensure that the horizontal detection surface 213 of the horizontal connecting member 2111 can remain parallel to the horizontal plane of the base 120 when the horizontal conversion height measuring member 210 is measured, the present invention performs two-way limiting on the horizontal connecting member 2111 of the connecting frame 211 and the vertical conversion connecting member 2112, that is, the width of the horizontal rotation groove 111 is smaller than the length of the horizontal connecting member 2111, so as to limit the 360-degree rotation of the horizontal connecting member 2111, and at the same time, the spacing between the limit bolt 520 and the measuring steel ball 223 on the detection main rod 221 is set. The length of the vertical conversion connector 2112 is smaller than that of the vertical conversion connector 2112 to limit the 360-degree rotation of the vertical conversion connector 2112. This ensures that the user does not easily get stuck when placing the parallelism detection device 10 into the gap of the die-cutting machine 21. It also ensures that the vertical conversion connector 2112 can always flexibly abut against the measuring steel ball 223 to form a detection path. It also ensures that when the measuring contact piece 212 of the horizontal connector 2111 contacts the measuring point, the horizontal detection surface 213 of the horizontal connector 2111 can remain parallel to the horizontal plane of the base 120 to ensure the accuracy of the detection result.

[0073] like Figure 8 As shown, in one embodiment, the stopper assembly 500 is located in the receiving groove 124. It can be understood that by setting the stopper assembly 500 in the receiving groove 124 and cooperating with the sliding block 121 to be set on the side wall of the receiving groove 124, the receiving groove 124 can accommodate the stopper assembly 500 and the sliding block 121, so that the measuring height of the parallelism detection device 10 in the vertical direction Y can be effectively reduced, so as to improve the adaptability of the parallelism detection of the die-cutting machine 21 with a smaller gap.

[0074] Furthermore, if Figure 8 As shown, in one embodiment, the sliding block 121 is arranged at one end of the receiving groove 124 away from the horizontal conversion height measuring member 210, the depth of the receiving groove 124 is less than the height of the fixing seat 130, and the height of the limiting assembly 500 is not greater than the depth of the receiving groove 124. It can be understood that since the sliding block 121 is arranged at one end of the receiving groove 124 away from the horizontal conversion height measuring member 210, the horizontal conversion height measuring member 210 can be located on one side of the sliding block 121. When it is necessary to perform parallelism detection on the die-cutting machine 21 with a smaller gap, the horizontal conversion height measuring member 210 can be adjusted to the lowest position of the sliding block 121, so that the measuring contact member 212 of the horizontal conversion height measuring member 210 is partially protruded and arranged in the receiving groove 124. In this way, the measuring height of the horizontal conversion height measuring member 210 in the vertical direction Y of the base 120 can be minimized, thereby improving the detection of the parallelism of the die-cutting machine 21 with a smaller gap.

[0075] See also Figure 7 The present application also provides a lithium battery die-cutting machine parallelism detection system 20, including a die-cutting machine 21 and the parallelism detection device 10 described in any of the above embodiments. It can be understood that by using the parallelism detection device 10 to detect different measuring points on the gap between the upper and lower plates of the die-cutter 21, the detection results at each measuring point can be obtained, and the measurement results of multiple measuring points can be used to determine whether the gap between the upper and lower plates of the die-cutter 21 is parallel. When the parallelism detection device 10 of the present invention is used for measurement, it is not easy to get stuck during measurement, thereby reducing the wear between the measuring contact member 212 of the horizontal conversion height measuring member 210 and the upper and lower plates of the die-cutter 21, thereby ensuring the service life of the horizontal conversion height measuring member 210. It is not only simple and accurate to operate, but also extends the horizontal measurement distance of the parallelism detection device 10, so that the user can better detect the measurement points that are difficult to approach in the middle of the die-cutter 21. In this way, it is ensured that the die-cutter 21 has a high flatness when die-cutting the battery pole piece, thereby ensuring that the die-cutter 21 can quickly and smoothly die-cut the battery pole piece to be cut, so as to obtain a battery pole piece with a high incision flatness and no powder falling, which is particularly suitable for the detection of the parallelism of a small gap and an extra-large die-cutter 21.

[0076] Compared with the prior art, the present invention has at least the following advantages:

[0077] 1. The above-mentioned parallelism detection device 10, by horizontally setting the detection micrometer 220 on the mounting seat 100, so that the extension direction of the detection micrometer 220 can be parallel to the horizontal plane where the mounting seat 100 is located. Since the horizontal conversion height measuring piece 210 is rotatably set on the mounting seat 100, when the horizontal conversion height measuring piece 210 contacts the upper plate of the die-cutting machine 21, the horizontal conversion height measuring piece 210 is blocked by the upper plate, so that the horizontal conversion height measuring piece 210 can swing in the direction close to the detection micrometer 220 and abut against the detection micrometer 220, so that the horizontal conversion height measuring piece 210 can form a detection path with the detection micrometer 220, so as to realize accurate measurement of the parallelism of the gap between the upper and lower plates of the die-cutting machine 21, thereby realizing that the horizontal conversion height measuring piece 210 can rotate from vertical measurement to horizontal measurement during measurement. In this way, not only the accuracy of the detection result of the parallelism detection device 10 is improved, and the phenomenon that the measurement error of the hand-cranked lever-type internal diameter micrometer 222 is large, causing the parallelism measurement error between the upper and lower plates of the die-cutting machine 21 is large, but also when the horizontal conversion height measuring piece 210 and the detection micrometer 220 are swung and abutted, a Z-shaped connection structure can be formed with the detection micrometer 220, thereby effectively reducing the height of the parallelism detection device 10 in the vertical direction Y, so that the parallelism detection device 10 is thinner in thickness, so that the parallelism detection device 10 can be well extended to the die-cutting machine 21 with a smaller gap to perform accurate parallelism detection, thereby ensuring the accuracy of the detection result of the parallelism detection device 10, and effectively avoiding the measurement error of the hand-cranked lever-type internal diameter micrometer 222. The phenomenon of large parallelism measurement error between the upper and lower plates of the die-cutting machine 21 is caused, and the measuring distance of the measuring component 200 in the horizontal direction X is extended, so that users can measure some measuring points that are difficult for users to approach. For example, for some large die-cutting machines 21, when it is necessary to measure the parallelism of the middle parts of the upper and lower plates of the die-cutting machine 21, the user can easily detect the parallelism of the middle parts of the upper and lower plates of the die-cutting machine 21, that is, under the condition of ensuring that the parallelism detection device 10 has high accuracy, the adaptability of the parallelism detection device 10 to the gap detection of different die-cutting machines 21 is also improved, and it is ensured that after die-cutting, a battery electrode with high incision flatness and no powder falling can be obtained, that is, a battery electrode with better quality is obtained, which is particularly suitable for the detection of the parallelism of super-large die-cutting machines 21 with small gaps.

[0078] 2. The above-mentioned parallelism detection device 10, by rotating the horizontal conversion height measuring piece 210 and setting it on the mounting seat 100, allows the user to place the horizontal conversion height measuring piece 210 into the gap of the die-cutting machine 21 more quickly and smoothly, thereby effectively avoiding the phenomenon of jamming that is easy to occur during the measurement process, and effectively reducing the wear between the horizontal conversion height measuring piece 210 and the measuring point, thereby extending the service life of the horizontal conversion height measuring piece 210.

[0079] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
