Description

Technical Field

[0001] This invention relates to the field of electrode cutting technology, and more specifically to a laser-guided fixed-cut waste removal mechanism. Background Technology

[0002] Lithium-ion battery cell manufacturing is a mid-stage process in the overall battery production process. Die-cutting involves cutting evenly spaced tabs onto the electrode roll. Based on the die-cutting method, it can be divided into metal die-cutting and laser die-cutting. Currently, laser die-cutting typically uses a flying cut method, where the shape of the tabs on the electrode roll is formed by a combination of the electrode's movement and the laser's galvanometer's trajectory—that is, dynamically cutting the tab shape. This requires precise control of the material strip and the galvanometer's movement, which can easily lead to processing errors during actual production. If a fixed-cut tab shape is used, where the laser and material strip are relatively stationary during die-cutting, processing errors caused by material strip vibration, uneven movement speed, or uneven tension can be avoided.

[0003] A significant issue with laser-cut electrode tabs is that processing efficiency is limited by waste removal time. The entire electrode tab cutting process includes the electrode strip moving into position, laser cutting, and waste removal; waste removal typically takes a considerable amount of time, necessitating an increase in waste removal speed. Therefore, a rapid waste removal mechanism for laser-cut electrode tabs is required. Summary of the Invention

[0004] The purpose of this invention is to provide a laser-cut waste removal mechanism. This waste removal mechanism can quickly switch between waste adsorption and blowing states through a reciprocating waste removal adsorption plate to quickly remove waste from the electrode tabs.

The interior of the waste discharge adsorption plate is a hollow groove. The top of the end of the waste discharge adsorption plate that contacts the waste discharge sheet metal platform is provided with an adsorption hole, and the adsorption hole corresponds to the electrode tab waste cutting area.

[0009] An adsorption plate drive motor is located on the side of the support frame, and the rotation shaft of the adsorption plate drive motor is connected to the end of the waste discharge adsorption plate away from the waste discharge sheet metal platform, so as to drive the waste discharge adsorption plate to rotate downward.

[0013] A vertical pressure belt module is provided at one end of the support frame, and connecting plates are provided on both sides of the vertical pressure belt module to connect with the vertical pressure belt module so as to be driven by the vertical pressure belt module to move in the vertical direction;

[0014] A pressure bar, one end of which is connected to the connecting plate so that it can be moved by the connecting plate;

[0015] A pressing sheet metal plate is located at the other end of the pressing rod to work together with the waste discharge sheet metal platform to press the material strip.

[0016] Optionally, the waste discharge mechanism includes auxiliary rollers disposed on both sides of the support frame, and the material belt slides over the auxiliary rollers.

[0022] A dust removal adsorption chamber is disposed on the dust removal support frame, and the opening of the dust removal adsorption chamber faces the waste discharge sheet metal platform;

[0023] The dust removal duct has one end connected to the dust removal adsorption chamber and the other end bypassing the dust removal support frame and connected to an external exhaust device.

[0024] Optionally, the waste discharge mechanism includes a dust removal lifting cylinder, which is disposed at the other end of the support frame, and the telescopic shaft of the dust removal lifting cylinder is connected to the dust removal support frame to drive the dust removal support frame to move in the vertical direction.

[0025] Optionally, the waste discharge mechanism includes:

[0026] A base frame is disposed at the bottom of the support frame to support the support frame;

[0027] A left-right adjustment device is provided on the top of the base frame and between the base frame and the support frame to drive the support frame to move;

An air block can be set on the side of the waste removal adsorption plate away from the drive motor, and the air passage in the air block can fit with the groove opening of the hollow groove of the waste removal adsorption plate. When the conveyor belt carries the electrode tab to the waste discharge sheet metal platform, the adsorption air passage in the air block can fit with the opening of the empty slot, so that the adsorption hole can adsorb the waste material after the electrode tab is cut. Then, the adsorption plate drive motor drives the waste discharge adsorption plate to rotate downward so that the opening of the empty slot fits with the blowing air passage, so that the waste material can be blown out. Then, the waste discharge adsorption plate is driven to rotate back to the horizontal position to continue adsorbing waste material. This cycle can quickly discharge the waste material after the electrode tab is cut.

[0053] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

Figure 2 This is an axonometric view of a waste discharge platform of a laser-cut waste discharge mechanism according to an embodiment of the present invention.

Figure 4 This is a cross-sectional three-dimensional view of the waste discharge pipe of a laser-cut waste discharge mechanism according to an embodiment of the present invention. Figure 5This is a three-dimensional view of the waste removal adsorption plate of a laser-cut waste removal mechanism according to an embodiment of the present invention. In this invention, the waste removal mechanism may include: a support frame 1, a waste removal sheet metal platform 2, a waste removal adsorption plate 3, an adsorption plate drive motor 5, an air block 6, and a waste removal pipe 10. The waste removal sheet metal platform 2 can be disposed on the top of the support frame 1, and can be used to carry the material strip for electrode laser cutting. A waste removal adsorption plate 3 can be provided at one end of the waste removal sheet metal platform 2. The waste removal adsorption plate 3 is not connected to the waste removal sheet metal platform 2, and the interior of the waste removal adsorption plate 3 can be a hollow groove 7. An adsorption hole 4 can be provided at the top of the end of the waste removal adsorption plate 3 that contacts the waste removal sheet metal platform 2. The adsorption hole 4 corresponds to the cutting area of ​​the electrode waste. An adsorption plate drive motor 5 can be provided on the side of the support frame 1. The rotation shaft of the adsorption plate drive motor 5 can be connected to the end of the waste removal adsorption plate 3 away from the waste removal sheet metal platform 2, thereby driving the waste removal adsorption plate 3 to rotate downwards. The air block 6 can be positioned on the side of the waste discharge adsorption plate 3 away from the adsorption drive motor 5, and an adsorption air passage 8 can be provided in the horizontal direction inside the air block 6. This adsorption air passage 8 can be connected to an external adsorption air pipe elbow. An outflow air passage 9 can be provided in the inclined direction inside the air block 6. This outflow air passage 9 can be connected to an external outflow air pipe elbow. When the empty slot 7 is horizontal, the opening of the empty slot 7 can fit against the adsorption air passage 8, thereby generating suction force in the adsorption hole 4. When the empty slot 7 is inclined, the opening of the empty slot 7 can fit against the outflow air passage 9, thereby allowing air to blow from the adsorption hole 4. A waste discharge pipe 10 can be provided below the waste discharge sheet metal platform 2 and the waste discharge adsorption plate 3. The top opening of the waste discharge pipe 10 can be located below the waste discharge adsorption plate 3.

[0055] In this invention, the feed strip can be intermittently fed. When the feed strip reaches the waste removal sheet metal platform 2, it can stop moving, and then the laser can cut the tabs on the feed strip. After cutting, the waste on the tabs can fall onto the adsorption holes 4 on the waste removal adsorption plate 3, and then the feed strip can continue to move forward to carry away the cut tabs. During laser cutting, the waste removal adsorption plate 3 can be in a horizontal state, with the slot 7 opening and the adsorption air passage 8 in contact. The adsorption holes 4 generate suction to adsorb the cut waste, allowing the waste to be adsorbed onto the adsorption holes 4. As the conveyor belt continues to move, the adsorption plate drive motor 5 can drive the waste discharge adsorption plate 3 to rotate downwards. Then, the opening of the empty slot 7 can fit with the blowing air path, so that the adsorption hole 4 can blow out airflow, thereby blowing the waste into the waste discharge pipe 10. Then, the adsorption plate drive motor 5 can continue to drive the waste discharge adsorption plate 3 back to the initial position to continue adsorbing the waste from the next stage of laser cutting. This cycle can be repeated to quickly discharge the waste after the tab cutting.

[0056] In one embodiment of the present invention, such as Figure 1 As shown, the waste discharge mechanism may include: a vertical pressing module 11, a pressing rod 13, and a pressing sheet metal plate 14. The vertical pressing module 11 can be disposed at one end of the support frame 1, and connecting plates 12 can be provided on both sides of the vertical pressing module 11. The connecting plates 12 can be connected to the vertical pressing module 11, and thus can be driven by the vertical pressing module 11 to move vertically. One end of the pressing rod 13 can be connected to the connecting plate 12, and thus can be driven by the connecting plate 12 to move vertically. The other end of the pressing rod 13 can be provided with a pressing sheet metal plate 14. The pressing sheet metal plate 14 can be driven by the pressing rod 13 to move vertically, thereby cooperating with the waste discharge sheet metal platform 2 to press the material strip. When the material strip moves the electrode tabs onto the waste discharge sheet metal platform 2, the vertical pressing module 11 can drive the connecting plate 12 to press down, which in turn can cause the pressing sheet metal sheet 14 to press down, pressing the material strip onto the waste discharge sheet metal platform 2 to fix the material strip, so that the laser can accurately position the electrode tabs on the material strip.

[0057] In one embodiment of the present invention, such as Figure 1 As shown, the waste discharge mechanism may include auxiliary rollers 15. The auxiliary rollers 15 may be disposed on both sides of the support frame 1. The material belt can slide over the auxiliary rollers 15. The auxiliary rollers 15 allow the material belt to be flatter, thereby enabling smoother transmission of the electrode tabs.

[0058] In one embodiment of the present invention, such as Figure 2 As shown, the waste discharge mechanism may include platform adsorption holes 16. The platform adsorption holes 16 may be set on both sides of the adsorption holes 4 of the waste discharge adsorption plate 3. When the material belt carries the electrode to the waste discharge sheet metal platform 2 and the laser cuts the electrode, the platform adsorption holes 16 can adsorb the material belt to prevent the material belt from wrinkling and affecting the cutting of the electrode.

[0059] In one embodiment of the present invention, the bottom of the opening of the waste discharge pipe 10 can be a 45° slope. When the adsorption plate drive motor 5 moves the waste discharge adsorption plate 3 downward, the waste discharge adsorption plate 3 will be limited at about 45°. At this time, the opening of the empty groove 7 can fit with the blowing air passage 9, and the adsorption hole 4 can blow the waste into the waste discharge pipe 10. The 45° bottom of the opening of the waste discharge pipe 10 can make as much waste as possible blown into the waste discharge pipe 10, and can also reduce the rotation angle of the waste discharge adsorption plate 3, so that the waste discharge adsorption plate 3 can return to the initial position more quickly.

[0060] In one embodiment of the present invention, such as Figure 1As shown, the pressure bar 13 and the pressure sheet 14 can move relative to each other in the vertical direction. A spring 17 can be provided between the pressure bar 13 and the pressure sheet 14. The spring 17 can elastically push the pressure sheet 14 downward a certain distance. When the pressure sheet 14 is driven to press the material strip, the spring 17 can have a certain buffering effect to prevent the pressure sheet 14 from continuing to press down and damaging the surface of the material strip.

[0061] In this invention, dust may be generated when the laser cuts the tabs. If the dust is not cleaned for a long time, it may affect the cutting of the tabs. Therefore, in one embodiment of this invention, as... Figure 1 As shown, the waste discharge mechanism may include: a dust removal support frame 18, a dust removal adsorption chamber 19, and a dust removal pipe 20. The dust removal support frame 18 can be disposed at the other end of the support frame 1 and can be slidably connected to the support frame 1. The dust removal adsorption chamber 19 can be disposed on the dust removal support frame 1, and the opening of the dust removal adsorption chamber 19 can face the waste discharge sheet metal platform 2. One end of the dust removal pipe 20 can be connected to the dust removal adsorption chamber 19, and the other end can bypass the dust removal support frame 18 and be connected to an external exhaust device. The connection of the dust removal pipe 20 to the exhaust device can form an airflow within the dust removal pipe 20, causing the opening of the dust removal adsorption chamber 19 to generate a certain adsorption force. When the electrode is cutting on the waste discharge sheet metal platform 2, the dust generated by cutting can be adsorbed by the dust removal adsorption chamber 19, avoiding the accumulation of dust.

[0062] In one embodiment of the invention, such as... Figure 1 As shown, the waste discharge mechanism may include a dust removal lifting cylinder 21. The dust removal lifting cylinder 21 can be located at the other end of the support frame 1, and its telescopic shaft can be connected to the dust removal support frame 18, thereby driving the dust removal support frame 18 to move vertically. When the conveyor belt needs to pass through the waste discharge mechanism, the dust removal lifting cylinder 21 can drive the dust removal support frame 18 upwards. This facilitates the conveyor belt passing through the waste discharge mechanism.

[0063] In one embodiment of the present invention, such as Figure 6As shown, the waste discharge mechanism may include: a base frame 22, a left-right adjustment device 23, and a front-back adjustment device 24. The base frame 22 can be disposed at the bottom of the support frame 1, thereby supporting the support frame 1. The left-right adjustment device can be disposed at the top of the base frame 22 and between the base frame 22 and the support frame 1, thereby enabling the support frame 1 to move left and right. The front-back adjustment device 24 can be disposed on the left-right adjustment device 23 and between the left-right adjustment device 23 and the support frame 1, thereby enabling the support frame 1 to move back and forth. The left-right adjustment device 23 and the front-back adjustment device 24 can adjust the support frame 1 to a designated position.

[0064] In one embodiment of the present invention, such as Figure 6 As shown, the waste discharge mechanism may include a shock-absorbing marble 25. The shock-absorbing marble 25 can be disposed on top of the base frame 22 and between the left-right adjustment device 23 and the base frame 22. The shock-absorbing marble 25 can reduce the impact of the left-right adjustment device 23 and other moving components on the accuracy of the laser cutting tabs.

[0065] Through the above technical solution, the laser-cut waste removal mechanism provided by the present invention includes a support frame, and a waste removal sheet metal platform can be provided on the top of the support frame. The material strip can bring the electrode tab to the waste removal sheet metal platform for laser cutting. A waste removal adsorption plate can be set at one end of the waste removal sheet metal platform and is not connected to the waste removal sheet metal platform. The interior of the waste removal adsorption plate is a hollow groove, and an adsorption hole can be provided at the end of the waste removal adsorption plate that contacts the waste removal sheet metal platform. The adsorption hole can correspond to the cutting area of ​​the electrode tab waste. An adsorption plate drive motor can be provided on the side of the support frame. The rotation shaft of the adsorption plate drive motor can be connected to the end of the waste removal adsorption plate away from the waste removal sheet metal platform, thereby driving the waste removal adsorption plate to rotate. An air block can be set on the side of the waste removal adsorption plate away from the drive motor, and the air passage in the air block can fit with the groove opening of the hollow groove of the waste removal adsorption plate. When the conveyor belt carries the electrode tab to the waste discharge sheet metal platform, the adsorption air passage in the air block can fit with the opening of the empty slot, so that the adsorption hole can adsorb the waste material after the electrode tab is cut. Then, the adsorption plate drive motor drives the waste discharge adsorption plate to rotate downward so that the opening of the empty slot fits with the blowing air passage, so that the waste material can be blown out. Then, the waste discharge adsorption plate is driven to rotate back to the horizontal position to continue adsorbing waste material. This cycle can quickly discharge the waste material after the electrode tab is cut.
