Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As discussed in the background, the blanking gap adjustment times in the prior art designs are long, affecting the utilization of the equipment. The inventor of the present application has found that one of the reasons is that the upper cutter in the conventional design is mounted on the mounting surface of the upper cutter seat, and the upper cutter is spaced from the mounting surface of the lower cutter seat. For example, as shown in fig. 1, the upper cutter 14 is mounted on one side of the upper cutter seat 12, the cutting edge surface 142 of the upper cutter is the surface of the upper cutter 14 facing away from the upper cutter seat 12, the lower cutter 18 is mounted on one side of the lower cutter seat 16, and the cutting edge surface 182 of the lower cutter abuts against the lower cutter seat 16. When the cutting edge of the upper cutter 14 or the lower cutter 18 becomes dull or the cutter is replaced, the interval between the two cutter seats needs to be readjusted to secure the gap between the upper cutter and the lower cutter. However, since the blanking gap is relatively small, and the distance between the mounting surfaces of the two tool holders is usually different in magnitude compared with the blanking gap, multiple tests and long-time adjustment are required to ensure the adjustment accuracy of the blanking gap.

In order to solve the above problems, the present application provides a cutting device, which can better improve the above problems.

FIG. 2 shows a schematic structural view of an upper blade assembly and a lower blade assembly in one embodiment; FIG. 3 is a schematic diagram of the cutting device of an embodiment of the present application; FIG. 4 is a schematic view of the cutting apparatus of FIG. 3 from another perspective; for the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Referring to fig. 2 to 4, the cutting device in an embodiment of the present application includes a power source 20, a transmission mechanism 21, a base 22, a connecting seat 23, an upper cutting assembly 24, a lower cutting assembly 26, and a position adjusting mechanism 27.

The lower cutting assembly 26 is fixed relative to the frame 22 during cutting, and cooperates with the upper cutting assembly 24 to complete cutting of the cell tab.

In some embodiments, the power source 20 may be a driving motor, and the transmission mechanism 21 includes a crankshaft 212 connected to an output end of the driving motor, a swing link 214 connected to the crankshaft 212 at one end, and a transmission block 216 connected to the other end of the swing link 214. The transmission block 216 is fixedly connected with the connecting seat 23, the driving motor outputs rotary output, and the rotary output of the driving motor is converted into reciprocating motion of the connecting seat 23 in the cutting direction through the crankshaft 212, the swing rod 214 and the transmission block 216, so that the upper cutting component 24 is driven to perform cutting action. It can be understood that the power source 20 in the existing design is usually a driving cylinder, but the response time of the driving cylinder is long, and is limited by the precision of the pneumatic driving mode, the cutting efficiency and the precision cannot be effectively guaranteed, and the driving mode of combining the driving motor with the crankshaft 212 not only improves the cutting efficiency, but also further improves the cutting precision.

In the embodiment of the present application, the upper cutting assembly 24 includes an upper tool seat 242 and an upper cutter 244 disposed on the upper tool seat 242, and a cutting edge surface 246 of the upper cutter abuts against one side of the upper tool seat 242; the lower cutting assembly 26 includes a lower blade seat 262 opposite the upper blade seat 242 in the first direction, and a lower blade 264 disposed on the lower blade seat 262 with a blade surface 266 of the lower blade abutting a side of the lower blade seat 262. Specifically, the upper tool apron 242 and the lower tool apron 262 are disposed opposite to each other in the first direction, and the upper cutter 244 and the lower cutter 264 are respectively located on both sides of the upper tool apron 242 and the lower tool apron 262 opposite to each other in the first direction. That is, the mounting surfaces of the upper tool holder 242 and the lower tool holder 262 for mounting the cutting tools are opposed to each other in the first direction, and abut against the edge surfaces of the corresponding cutting tools.

It is easy to understand, in the existing design, because blanking clearance is less, and the interval of the installation face of two blade holders has different orders of magnitude than blanking clearance usually to cause the blanking clearance that needs to adjust once more after the tool changing, adjust inefficiency, adjust for a long time. In the embodiment of the application, the mounting surfaces of the two tool apron are opposite to each other and are abutted against the blade surfaces of the cutters, so that the distance between the mounting surfaces of the two tool apron is the blanking gap of the cutter edges of the two cutters. So, can guarantee to go up the blanking clearance between cutter and the lower cutter, and need not to readjust the interval between blade holder and the lower blade holder, conveniently go up the installation of cutter and lower cutter, and adjust the precision and compare in prior art higher.

It should be noted that the first direction is perpendicular to the cutting direction of the cutting device. In particular, in the embodiment shown in fig. 2, the cutting edge face 246 of the upper cutter and the cutting edge face 266 of the lower cutter oppose each other in a first direction, which is the left-right direction as shown.

Fig. 5 is a schematic view showing a structure of a position adjusting mechanism of the cutting apparatus shown in fig. 3.

In some embodiments, the cutting device further comprises a position adjustment mechanism 27 coupled to the lower blade seat 262, the position adjustment mechanism 27 configured to urge the lower blade seat 262 toward or away from the upper blade seat 242 in the first direction. In this way, the position adjustment mechanism 27 adjusts the blanking gap. Specifically, the cutting device further includes a support 30, the support 30 is disposed on the base 22, the lower tool post 262 is disposed on the support 30 and is movable relative to the support 30 in a first direction, and the position adjustment mechanism 27 is connected to the lower tool post 262 and is capable of driving the lower tool post 262 to move on the support 30 in the first direction, so as to adjust the blanking gap.

One end of the first adjusting member 270 is threadedly connected to the adjusting seat 272, and the other end is used for abutting against the lower tool apron 262, so as to drive the lower tool apron 262 to move away from the adjusting seat 272 along the first direction. The second adjusting member 278 has one end connected to the adjusting seat 272 and the other end screwed to the lower tool post 262, so as to operatively drive the lower tool post 262 to move toward the adjusting seat 272 along the first direction, so that the lower tool post 262 abuts against one end of the first adjusting member 270 away from the adjusting seat 272.

Illustratively, the position adjustment mechanism 27 includes two first adjustment members 270 and a second adjustment member 278 positioned between the two first adjustment members 270. During the adjustment process, the second adjustment member 278 may be adjusted to drive the lower tool apron 262 to move close to the adjustment seat 272, so as to ensure that the end of the first adjustment member 270 away from the adjustment seat 272 abuts against the lower tool apron 262, and then the two first adjustment members 270 may be adjusted to drive the lower tool apron 262 to move away from the adjustment seat 272. It will be understood that the blanking gap is generally determined by the thickness of the material to be cut, and that the influence of the blanking gap on the blanking force is governed by the fact that the smaller the gap, the greater the compressive stress in the deformation zone, the lower the tensile stress, the greater the resistance to deformation of the material, and the greater the blanking force. On the contrary, the larger the gap is, the larger the tensile stress in the deformation zone is, and the deformation resistance is reduced, generally, when the blanking force reaches 5-10% of the material thickness, the blanking force is not obviously reduced. Therefore, in order to achieve a better blanking effect, the blanking gap is generally less than 10% of the thickness of the cutting material, so the blanking gap for cutting the battery tab is generally several wires, and the space between the lower tool apron 262 and the upper tool apron 242, that is, the blanking gap of the cutting device, can be precisely adjusted by the cooperation of the first adjusting piece 270 and the second adjusting piece 278.

In some embodiments, the first adjustment member 270 includes a first threaded rod 274 and a nut 276 that mates with the first threaded rod 274; one end of the first screw 274 is screwed to the adjusting seat 272 and penetrates out from the side of the adjusting seat 272 far away from the lower tool apron 262, and the nut 276 is screwed to the part of the first screw 274 penetrating out from the side of the adjusting seat 272 far away from the lower tool apron 262. In this way, the fitting tightness of the first screw 274 and the adjustment seat 272 is ensured by the nut 276, thereby further improving the adjustment accuracy of the blanking gap. Further, the end of the first screw 274 is further provided with a supporting portion (not shown) for supporting the lower tool apron 262, so as to ensure that the first screw 274 is in full contact with the lower tool apron 262, and further ensure the adjustment accuracy.

In some embodiments, the second adjusting member 278 includes a second screw 275 and a limiting portion 277 located at an end of the second screw 275 far away from the lower tool post 262, an end of the second screw 275 far away from the lower tool post 262 penetrates through the adjusting seat 272, and the limiting portion 277 is configured to keep the second screw 275 axially fixed relative to the adjusting seat 272 when the second screw 275 drives the lower tool post 262 to move toward the adjusting seat 272. Specifically, the adjusting seat 272 has a through hole, one end of the second screw 275 far away from the lower tool holder 262 extends out of the through hole, and the limiting portion 277 is fixedly connected to one end of the second screw 275 extending out through the through hole. Wherein, the radial dimension of the limiting portion 277 is greater than the radial dimension of the via hole, when the second screw 275 is rotated along the predetermined direction, because the adjusting seat 272 is fixed on the support 30, under the reaction force of the lower tool apron 262, the limiting portion 277 is tightly pressed against the adjusting seat 272 to be limited, the second screw 275 is continuously rotated, and the lower tool apron 262 is driven to move towards the adjusting seat 272, thereby being tightly pressed against the end of the first screw 274.

In some embodiments, the position adjustment mechanism 27 further includes a locking mechanism for positioning the lower tool holder 262 on the support 30. Specifically, the locking mechanism includes at least two locking members 31, the lower blade holder 262 is provided with locking holes, and the locking members 31 are inserted into the corresponding locking holes and are in threaded connection with the support 30, so as to fasten the lower blade holder 262 to the support 30 after the completion of the blanking gap adjustment. So, guarantee cutting device's blanking clearance and keep stable, when changing the cutter, need not readjust labour saving and time saving.

In order to ensure the blanking efficiency, in some embodiments, the cutting device further includes a pressing mechanism 28 for pressing the workpiece to be cut, and the pressing mechanism 28 is disposed on the connecting seat 23 and presses the workpiece to be cut when the upper cutter 244 performs the cutting action, so as to ensure the cutting precision. Specifically, the pressing mechanism 28 includes a pressing member 284 for pressing the workpiece to be cut, and a driving element 282 mounted on the connecting base 23, wherein the driving element 282 is configured to drive the pressing member 284 to approach the workpiece to be cut so as to press the workpiece to be cut. In one embodiment, the driving element 282 may be a pressing cylinder having a telescopic end capable of reciprocating in the cutting direction, and the pressing member 284 is a pressing bar connected to the telescopic end of the pressing cylinder to press the workpiece to be cut when the upper cutter 244 performs the cutting action. In a preferred embodiment, the driving element 282 may be provided in plurality, and the driving elements 282 are spaced apart from each other, so that the pressing force applied by the pressing bar to the workpiece to be cut can be ensured to be uniform at different positions.

Further, the pressing mechanism 28 further includes a guiding member 286, and one end of the guiding member 286 is connected to the pressing member 284, and the other end is slidably connected to the connecting seat 23. Specifically, the guiding element 286 is a guiding rod, one end of the guiding rod is fixedly connected to the pressing strip, and the other end of the guiding rod is slidably connected to the connecting seat 23 in the cutting direction. Therefore, the uniformity of the pressing force applied to the workpiece to be cut by the pressing strip at different positions is further ensured, and the cutting effect is improved.

It should be noted that when different types of workpieces to be cut are pressed, the magnitude of the pressing force can be changed by adjusting the air pressure of the pressing air cylinder, which is well known in the art and therefore will not be described herein.

It is particularly emphasized that the telescoping end of the drive member 282 reciprocates to have an initial position and an extreme position; when the upper blade holder 242 and the lower blade holder 262 are at a minimum distance in the cutting direction, the telescopic end of the drive member 282 is located between the initial position and the extreme position. In the process of working, during the downward movement of the connecting seat 23, the upper cutter 244 and the pressing mechanism 28 are synchronously driven to move downward, at this time, the telescopic end of the driving element 282 extends out, and the pressing piece 284 presses the workpiece to be cut before the upper cutter 244 and the lower cutter 264 punch. The connecting base 23 continues to move downwards, the telescopic end of the driving element 282 retracts, but the pressing member 284 can be kept in a state of pressing the workpiece to be cut until the upper cutter 244 and the lower cutter 264 complete the cutting action. Thus, when the driving element 282 is an air cylinder, after the telescopic end of the driving element 282 drives the pressing member 284 to press the workpiece, the connecting seat 23 can also drive the lower cutting knife 264 to move continuously, so that the telescopic end of the driving element 282 is compressed. The pressure of the gas introduced into the driving element 282 can be changed, so that the pressure of the driving element 282 for pressing the workpiece to be cut can be changed, and the pressing effect of the workpiece to be cut can be ensured.
