Description

Technical Field

[0001] This utility model relates to the field of electrode feeding, and more particularly to the field of lithium battery electrode winding, specifically to an electrode feeding mechanism with a correction function. Background Technology

[0002] Electrode feeding mechanisms are primarily used in the production and manufacturing of lithium batteries, particularly in the automated feeding and processing of electrodes for lithium-ion batteries. With the rapid development of the new energy industry, lithium-ion batteries, as the main energy storage unit, are widely used in applications including, but not limited to, electric vehicles, energy storage systems, and portable electronic devices. Therefore, the technical level and performance requirements of electrode feeding mechanisms are becoming increasingly stringent, significantly impacting lithium battery winding production efficiency, product quality, and cost control.

[0003] The existing electrode feeding and alignment mechanism mainly consists of a positioning platform and a feeding guide plate. A fixed baffle is installed on the side of the positioning platform, and a movable push block that can move towards the fixed baffle is installed on the side of the positioning platform relative to the fixed baffle. Limit baffles are installed on both sides of the feeding guide plate. Currently, cut sheet electrodes generally need to be aligned at the positioning platform, and then a suction cup transports the electrode to the feeding guide plate for feeding and winding, thus completing the alignment and correction of the sheet electrodes.

[0004] However, although existing electrode feeding mechanisms play an important role in lithium battery production, they still have some obvious shortcomings. The existing electrode feeding and alignment process generally involves aligning the cut electrode at the positioning platform, and then placing the electrode onto the feed guide plate with baffles on both sides by a suction cup. However, there is a certain gap between the baffles on both sides of the guide plate, which may cause the electrode to tilt after being placed on the feed guide plate. This affects the alignment and positional accuracy of the electrode on the winding machine. In addition, there is a transfer action to move the electrode from the positioning platform to the feed guide plate by the suction cup. The alignment structure is complex and cannot reliably guarantee the positional accuracy of the electrode on the feed guide plate, thus affecting the accuracy of subsequent winding and the quality of the finished product. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide an electrode feeding mechanism with a correction function, so as to solve the technical problem that the correction control structure of the existing electrode correction mechanism in the background art is complex, making it difficult to control the positional accuracy of electrode correction, thereby affecting the alignment and winding accuracy and quality of the subsequent winding of the electrode.

[0006] The objective of this utility model is achieved through the following means:

[0007] An electrode feeding mechanism with a correction function includes a correction platform, an X-axis slide and a Y-axis slide for driving the correction platform to move. A sliding plate that can slide along the Y-axis is provided on the Y-axis slide. The correction platform is mounted on the sliding plate via a sliding member extending along the X-axis. The X-axis slide is connected to the correction platform via a connector and can drive the correction platform to slide along the X-axis. The correction platform is provided with a correction suction cup slide for adsorbing the electrode, and a correction limiting baffle for correcting and aligning the electrode is connected to the correction platform. A driving member is provided on the correction platform for driving the correction suction cup slide to slide towards the correction limiting baffle. When the correction suction cup slide adsorbs the electrode and slides along the guide towards the correction limiting baffle, the correction limiting baffle makes a blocking contact with one side of the electrode. The reverse force of the correction limiting baffle allows the electrode to be corrected and make flush contact with the side of the correction limiting baffle.

[0008] Furthermore, as described above, the calibration suction cup slide is slidably mounted on the calibration platform via a guide member. The guide member extends along the sliding direction of the Y-axis slide, and the sliding direction of the calibration suction cup slide is perpendicular to the calibration limiting baffle, so that the driving member can drive the calibration suction cup slide along the guide member towards the Y-axis.

[0009] By setting the guide, the calibration suction cup slide can slide along the Y-axis, thereby bringing the adsorbed electrode closer to the calibration limit baffle. Driven by the calibration suction cup slide, the electrode can be corrected and the correction efficiency can be improved.

[0010] Furthermore, as described above, the calibration platform is provided with a mounting groove for mounting the calibration suction cup slide. The guide component consists of a guide sleeve and a guide shaft. The axial direction of the guide shaft extends along the Y-axis. The guide shaft is installed in the mounting groove. The calibration suction cup slide is coaxially connected to the guide shaft through the guide sleeve. The calibration suction cup slide is connected to the driving end of the driving component, so that the calibration suction cup slide can slide along the guide shaft under the drive of the driving component.

[0011] The set driving component can drive the calibration suction cup slide to slide along the guide shaft, so that the electrode adsorbed on the calibration suction cup slide can move closer to the calibration limit baffle and align with the side of the calibration limit baffle for correction and alignment, which can conveniently correct the electrode.

[0012] Optionally, the calibration suction cup slide is installed in the mounting groove so that it is flush with the upper surface of the calibration platform, thereby adsorbing and correcting the electrode on the calibration platform.

[0013] Furthermore, the calibration suction cup slide is provided with an adsorption hole for negative pressure adsorption of the electrode sheet. The adsorption hole is exposed on the upper surface of the calibration platform, and the calibration suction cup slide is connected to a negative pressure tube that communicates with the adsorption hole.

[0014] The exposed adsorption holes allow for negative pressure adsorption of the electrode on the calibration platform. By connecting to an external negative pressure control system via a negative pressure pipe, the suction force of the adsorption holes can be controlled. When the electrode is pressed against the side of the calibration limit baffle by the calibration suction cup slide, the electrode can be displaced on the calibration suction cup slide, thereby aligning the side of the electrode with the calibration limit baffle.

[0015] Further as described above, the connector includes a connecting shaft, a connecting block, and a connecting sleeve for mating the connecting shaft. A sliding seat that can slide along the X-axis is provided on the X-axis slide table. The sliding seat is provided with mounting holes for mating and installing the connecting sleeve. The connecting block is connected to the calibration platform. One end of the connecting shaft is connected to the connecting block, and the other end of the connecting shaft is mated with the connecting sleeve. The connecting shaft can slide along the axial direction of the connecting sleeve.

[0016] The X-axis slide is connected to the calibration platform via a connector, allowing it to pick up materials by moving along the X-axis. After the calibration suction cup slide on the calibration platform corrects the adsorbed electrode sheet, the X-axis slide drives the calibration platform to feed the corrected electrode sheet, thereby improving production efficiency and the alignment accuracy of the winding position when the electrode sheet is subsequently wound.

[0017] Furthermore, as described above, the calibration platform is provided with a plurality of negative pressure holes for adsorbing the electrode sheets, and the calibration platform is provided with adsorption channels that communicate with the negative pressure holes.

[0018] The negative pressure holes allow the corrected electrode sheets to be adsorbed and transported to the subsequent winding area via the movement of the X-axis slide. The adsorption channels and negative pressure holes improve the stability of the electrode sheet adsorption and positioning, thereby ensuring the positional accuracy of the electrode sheet after correction and improving the alignment and winding accuracy of the subsequent electrode sheet winding.

[0019] Furthermore, as described above, the correction limiting baffle is detachably mounted on the top of the correction platform by bolts, and the side of the correction limiting baffle near the correction suction cup slide serves as the reference surface. The setting of the correction limiting baffle provides a reference for the correction and alignment of the electrode, thereby pushing the electrode along the correction suction cup slide towards the reference surface of the correction limiting baffle, improving the efficiency of correction and alignment and the ease of use.

[0020] Furthermore, as described above, the sliding component includes a slider and a slide rail. The slider is mounted on a sliding base, and the slide rail is mounted on the bottom of the calibration platform and paired with the slider, so that the slide rail can slide along the slider.

[0021] The beneficial effects of this utility model are as follows: The calibration suction cup slide can adsorb the electrode sheet and slide it along the guide to the calibration limiting baffle, so that the calibration limiting baffle makes a blocking contact with one side of the electrode sheet. When the driving component drives the calibration suction cup slide after adsorbing the electrode sheet to slide towards the calibration limiting baffle, so that the electrode sheet contacts the calibration limiting baffle, the blocking of the calibration limiting baffle allows the electrode sheet to slide in a certain reverse direction on the calibration suction cup slide. This allows the side of the electrode sheet to align and make flush contact with the calibration limiting baffle, improving the stability and accuracy of the electrode sheet during the calibration process. The calibration platform can move in the X-axis and Y-axis directions through the X-axis slide and Y-axis slide, so that the calibration platform can be accurately positioned to the required position. This allows it to be moved to the loading area for loading the electrode sheet, and the electrode sheet can be easily transferred after calibration and correction, reducing the displacement deviation caused by the transfer after the electrode sheet calibration operation. This improves the alignment and winding accuracy and quality of the subsequent winding of the electrode sheet, and the calibration and correction structure is simple and easy to operate, improving the flexibility and accuracy of use.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] In this embodiment, refer to Figures 1-7 The electrode feeding mechanism with a calibration function includes a calibration platform 1, an X-axis slide 2 and a Y-axis slide 3 for driving the calibration platform 1 to move. The top of the Y-axis slide 3 is equipped with a sliding plate 4 that can slide along the Y-axis. The bottom of the calibration platform 1 is mounted on the sliding plate 4 via a sliding member 5, which extends along the X-axis. The X-axis slide 2 is connected to the calibration platform 1 via a connecting member 6 and can drive the calibration platform 1 to slide along the X-axis. The calibration platform 1 is equipped with two feeding devices for feeding the electrode. The calibration suction cup slide 7 is used for adsorption, and the top of the calibration platform 1 is connected to a calibration limiting baffle 8 for correcting the electrode. The calibration platform 1 is provided with a driving member 9 for driving the calibration suction cup slide 7 to slide towards the calibration limiting baffle 8. When the calibration suction cup slide 7 adsorbs the electrode and slides along the guide member 10 towards the calibration limiting baffle 8, the calibration limiting baffle 8 makes a blocking contact with one side of the electrode. The electrode can be corrected and made flush with the side of the calibration limiting baffle 8 by the reverse force of the calibration limiting baffle 8.

[0032] The established calibration platform provides a stable calibration area for the electrode, ensuring that the electrode can be stably adjusted and positioned during the calibration process.

[0033] In this embodiment, the calibration suction cup slide 7 is slidably mounted on the calibration platform 1 via a guide 10. The guide 10 extends along the sliding direction of the Y-axis slide 3, and the sliding direction of the calibration suction cup slide 7 is perpendicular to the calibration limiting baffle 8, allowing the driving member 9 to drive the calibration suction cup slide 7 to slide along the guide 10 towards the Y-axis. The guide 10 allows the calibration suction cup slide 7 to slide along the Y-axis, thereby bringing the adsorbed electrode closer to the calibration limiting baffle 8. Driven by the calibration suction cup slide 7, the electrode can be corrected and its alignment improved.

[0034] In this embodiment, refer to Figure 5 and Figure 6The calibration platform 1 has a mounting groove 11 for mounting the calibration suction cup slide 7. The calibration suction cup slide 7 is installed in the mounting groove 11 and exposed. The guide member 10 consists of a guide shaft 102 sleeve and a guide shaft 102. The axial direction of the guide shaft 102 extends along the Y-axis and is installed in the mounting groove 11. The calibration suction cup slide 7 is coaxially connected to the guide shaft 102 through the guide shaft 102 sleeve. The calibration suction cup slide 7 is connected to the driving end of the driving member 9, so that the calibration suction cup slide 7 can slide along the guide shaft 102 under the drive of the driving member 9. The driving member 9 can drive the calibration suction cup slide 7 to slide along the guide shaft 102, thereby allowing the electrode adsorbed on the calibration suction cup slide 7 to move closer to the calibration limiting baffle 8 and align with the side of the calibration limiting baffle 8 for correction and alignment, which can facilitate the correction and alignment of the electrode.

[0035] Specifically, the calibration suction cup slide 7 is installed in the mounting groove 11, making it flush with the upper surface of the calibration platform 1, so that the electrode sheet on the calibration platform 1 can be adsorbed and corrected.

[0036] Optionally, in this embodiment, the driving component 9 is a driving cylinder, and the extension and retraction end of the driving cylinder is connected to the correction suction cup slide 7.

[0037] The top of the calibration suction cup slide 7 is provided with an adsorption hole 12 for negative pressure adsorption of the electrode. The adsorption hole 12 is exposed on the upper surface of the calibration platform 1. The calibration suction cup slide 7 is connected to a negative pressure pipe 13 that communicates with the adsorption hole 12. The electrode on the calibration platform 1 can be adsorbed under negative pressure through the exposed adsorption hole 12. The negative pressure pipe 13 is connected to an external negative pressure control system, which can control the suction force of the adsorption hole 12. When the calibration suction cup slide 7 drives the electrode to press against the side of the calibration limiting baffle 8, the electrode can generate a certain displacement on the calibration suction cup slide 7, so that the side of the electrode can be aligned with the calibration limiting baffle 8.

[0038] In this embodiment, refer to Figure 2 The connector 6 includes a connecting shaft 61, a connecting block 62, and a connecting shaft 61 sleeve for mating the connecting shaft 61. The X-axis slide 2 is provided with a sliding seat 14 that can slide along the X-axis. The sliding seat 14 is provided with a mounting hole for mating and installing the connecting shaft 61 sleeve. The connecting block 62 is connected to the calibration platform 1. One end of the connecting shaft 61 is connected to the connecting block 62, and the other end of the connecting shaft 61 is mated with the connecting shaft 61 sleeve. The connecting shaft 61 can slide along the axial direction of the connecting shaft 61 sleeve.

[0039] The X-axis slide 2 is connected to the calibration platform 1 via the connector 6, allowing it to pick up materials by moving the calibration platform 1 along the X-axis. After the calibration suction cup slide 7 on the calibration platform 1 corrects the adsorbed electrode sheet, the X-axis slide 2 drives the calibration platform 1 to feed the corrected electrode sheet, thereby improving production efficiency and the alignment accuracy of the winding position when the electrode sheet is subsequently wound.

[0040] Specifically, the X-axis slide 2 simplifies the existing suction cup clamping and transfer structure, and the drive configuration of the X-axis slide 2 improves the accuracy and stability of electrode transfer on the calibration platform 1. Furthermore, its control structure is simple, while simultaneously improving the efficiency and accuracy of the calibration operation.

[0041] The calibration platform 1 is provided with negative pressure holes 15 for adsorbing electrode sheets, and an adsorption channel 16 communicating with the negative pressure holes 15 is provided on the calibration platform 1. The electrode sheets that have been corrected and aligned can be adsorbed through the negative pressure holes 15, and then transported to the subsequent winding area by the movement of the X-axis slide 2. The adsorption channel 16 and the negative pressure holes 15 improve the stability of the electrode sheet adsorption and positioning, thereby ensuring the positional accuracy of the electrode sheet after correction and alignment, and improving the alignment and winding accuracy of the subsequent electrode sheet winding.

[0042] The correction limiting baffle 8 is detachably installed on the top of the correction platform 1 by bolts, and the side of the correction limiting baffle 8 near the correction suction cup slide 7 serves as the reference surface. The setting of the correction limiting baffle 8 provides a reference for the correction and alignment of the electrode, thereby pushing the electrode towards the reference surface of the correction limiting baffle 8 via the correction suction cup slide 7, improving the efficiency of correction and alignment and the ease of use.

[0043] In this embodiment, refer to Figure 3 and Figure 5 The sliding member 5 includes a slider 51 and a slide rail 52. The slider 51 is mounted on the sliding seat 14, and the slide rail 52 is mounted on the bottom of the calibration platform 1 and paired with the slider 51 so that the slide rail 52 can slide along the slider 51.

[0044] Specifically, in this embodiment, the X-axis slide 2 and Y-axis slide 3 are composed of a lead screw drive module, and servo drive motors are connected to the X-axis slide 2 and Y-axis slide 3.

[0045] Specifically, in this embodiment, the working principle of correction and alignment is as follows: the cut electrode sheet is placed on the alignment platform 1 and adsorbed by the alignment suction cup slide 7, so that it is directly aligned by the drive component 9, ensuring the positional accuracy of the electrode sheet when it is unwound. When the electrode sheet is placed on the alignment platform 1, as an example, refer to... Figure 7The two ends of the electrode are set as A and B respectively. When the electrodes A and B are not on the same horizontal line, the electrode is adsorbed onto the upper surface of the calibration platform 1 by the calibration suction cup slide 7. Specifically, the suction force of the suction hole 12 can be controlled by connecting the negative pressure pipe 13 to the external negative pressure control system, so that when the electrode A or B reaches the calibration limit baffle 8, it can produce a certain displacement and slide on the calibration suction cup slide 7, thereby continuing to move the electrode closer to the calibration limit baffle 8, so that the electrodes A and B are simultaneously aligned on the reference surface and on the same horizontal line, thereby completing the calibration of the electrode.

[0046] The specific operation process in this embodiment is as follows: The X-axis slide 2 drives the calibration platform 1 to slide along the slide 5 via the connecting piece 6, so that the calibration platform 1 slides to the electrode feeding area. The electrode is placed on the calibration platform 1. The two calibration suction cup slides 7 can be used to attract the two ends of the electrode. The two driving pieces 9 can simultaneously drive the two calibration suction cup slides 7 after attracting the electrode to slide towards the calibration limiting baffle 8. When one end of the electrode contacts the reference surface of the calibration limiting baffle 8, the electrode can slide in a certain reverse direction on the calibration suction cup slide 7 due to the partition of the calibration limiting baffle 8. With the continued driving of the driving piece 9 towards the calibration limiting baffle 8, the side of the electrode can be moved. Alignment and alignment with the reference surface of the correction limit baffle 8 improves the stability and accuracy of the electrode sheet during the alignment process. The X-axis slide 2 and Y-axis slide 3 can drive the correction platform 1 to move in the X and Y axes, enabling the correction platform 1 to accurately position itself in the corresponding area. Specifically, the correction platform 1 can be moved to the loading area to load the electrode sheet, and the electrode sheet can be easily transferred after alignment and correction on the correction platform 1. This reduces the displacement deviation caused by the transfer after the electrode sheet alignment operation, thereby improving the alignment and winding accuracy and quality of the electrode sheet in subsequent winding. The correction and correction structure is simple and easy to operate, improving the flexibility and accuracy of use.
