Description

Technical Field

[0001] The utility model relates to the technical field of pole piece manufacturing equipment, in particular to a thermal composite pole piece adjustment mechanism and a pole piece thermal composite device. Background Art

[0002] The existing hot composite lamination process generally involves cutting the negative electrode sheet into pieces and feeding it between two layers of separators. After heating and pressurizing them with hot composite rollers, the negative electrode sheet and the separator are adhered and composited. Subsequently, the positive electrode sheet is cut into equal widths and alternately fed to the front and back of the composite tape through a feeding assembly, and then composited by hot composite rollers. Since the feeding of the positive and negative electrode sheets and the membrane conveying are both in a high-speed motion state, this places extremely high demands on the accuracy of the electrode feeding. Traditional equipment does not have a monitoring mechanism before the electrode sheets are fed, making it impossible to detect and calibrate the electrode offset in a timely manner. In most cases, only the offset of the electrode in a single direction in the direction of movement is considered, making it impossible to monitor and correct the offset in various directions before the electrode sheets are fed, such as the left and right sides of the electrode sheet's movement direction. Therefore, it is difficult to accurately control the alignment of the positive and negative electrode sheets after feeding before hot composite, which results in poor alignment of the positive and negative electrode sheets in the battery cell, leading to problems such as lithium powder shedding and poor performance consistency.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] Such as Figures 1 to 11As shown, a thermal composite electrode adjustment mechanism of this embodiment includes a feeding component 110, a correction component and a visual recognition component 130, the feeding component 110 includes a feeding table 122, the discharge end of the feeding table 122 is arranged toward the feeding material belt 200a, the feeding material belt 200a includes a diaphragm belt 210 and a first electrode 230 arranged in the diaphragm belt 210; the correction component is connected to the feeding table 122 in a transmission manner to adjust the position of the second electrode 220 located on the feeding table 122, the correction component includes a first correction member 121, a second correction member 123 and a third correction member 124, the first correction member 121 is used to adjust the second electrode 220 along the X direction The position is adjusted along the Y direction 340, and the second correcting member 123 and the third correcting member 124 are respectively used to adjust the position of the second pole piece 220 along the Y direction 350. The second correcting member 123 and the third correcting member 124 are arranged in sequence along the X direction 340; the X direction 340 is arranged parallel to the conveying direction of the second pole piece 220, and the Y direction 350 is arranged perpendicular to the conveying direction of the second pole piece 220, and the X direction 340 and the Y direction 350 are located in the same plane; the visual recognition component 130 is arranged toward the feeding table 122 and performs visual recognition on the second pole piece 220 placed on the feeding table 122, and the visual recognition component 130 is connected to the correcting component.

[0036] In this embodiment, the second electrode piece 220 is transported to the corresponding position of the first electrode piece 230 on the input material strip 200a by the feeding table 122 of the feeding assembly 110, so that the first electrode piece 230 and the second electrode piece 220 are bonded together through the diaphragm strip 210 and then thermally composited by the thermal composite assembly to obtain the composite material strip 200b. Among them, during the feeding process of the second electrode piece 220 by the feeding component 110, the position of the second electrode piece 220 located on the feeding table 122 is identified by the visual recognition component 130, and the position of the second electrode piece 220 is compared with the standard template parameters in the visual recognition component 130. If there is a deviation, the visual recognition component 130 transmits the correction signal to the correction component, and the feeding table 122 is corrected by the correction component to achieve position correction adjustment of the first electrode piece 230 placed on the feeding table 122, so that the second electrode piece 220 is accurately transported to the corresponding position on the feeding belt 200a through the feeding component 110, avoiding feeding errors, which is beneficial to ensuring the accurate alignment of the first electrode piece 230 and the second electrode piece 220 of the composite material belt 200b formed after thermal composite, thereby helping to avoid the problem of lithium powder loss in subsequent products and improving the consistency of product performance.

[0037] Further, the deviation correction assembly includes a first deviation correction member 121, a second deviation correction member 123, and a third deviation correction member 124. Among them, the first deviation correction member 121 is used to adjust the position of the second pole piece 220 along the X direction 340. The second deviation correction member 123 and the third deviation correction member 124 are arranged in sequence along the X direction 340 and are respectively used to adjust the position of the second pole piece 220 along the Y direction 350. Among them, the X direction 340 is parallel to the conveying direction of the second pole piece 220, the Y direction 350 is perpendicular to the conveying direction of the second pole piece 220, and the X direction 340 and the Y direction 350 are in the same plane, realizing three-axis adjustment of the second pole piece 220 in the plane. Thus, it can meet the position adjustment of the second pole piece 220 placed on the feeding table 122 for translation or arbitrary angle rotation in the plane, so that the position of the second pole piece 220 is adjusted to align with the standard position 400 to achieve the effect of precise deviation correction adjustment.

[0038] In one embodiment, the vision recognition assembly 130 includes a vision camera 131. The second pole piece 220 is rectangular, and any two corners of the second pole piece 220 are within the shooting range 133 of the vision camera 131. For the rectangular second pole piece 220, the positions of any two corners of the second pole piece 220 are photographed by the vision camera 131, and if the positions of any two corners of the second pole piece 220 are aligned with the corresponding standard positions 400, then the other two corners of the second pole piece 220 will also naturally be aligned with the corresponding standard positions 400, thereby ensuring that the position of the second pole piece 220 is aligned with the corresponding standard position 400.

[0039] In one embodiment, two corners on the same side of the second pole piece 220 are within the shooting range 133 of the vision camera 131. In actual operation, photographing two corners on the same side of the second pole piece 220 by the vision camera 131 is beneficial to reducing the shooting range 133 of the vision camera 131, avoiding using a larger vision camera 131 or increasing the distance between the vision camera 131 and the second pole piece 220 in order to obtain a larger shooting range 133, thereby being beneficial to reducing the equipment investment cost.

[0040] In one embodiment, the vision camera 131 includes two first cameras 1311, which are respectively used to photograph the positions of two corners of the second pole piece 220, so that the installation and arrangement of the vision camera 131 are more flexible. Further, the two corners on the front side of the second pole piece 220 along the conveying direction are respectively located in the shooting ranges 133 of the two first cameras 1311. When the feeding assembly 110 feeds the second pole piece 220, the two corners on the front side of the second pole piece 220 along the conveying direction first enter the feeding table 122 and enter the shooting ranges 133 of the first cameras 1311. Thus, the first cameras 1311 can photograph the second pole piece 220 in time and transmit signals to the deviation rectifying assembly, so that the deviation rectifying assembly can quickly perform timely deviation rectifying adjustment on the position of the second pole piece 220.

[0041] Furthermore, the vision camera 131 further includes two second cameras 1312. The two corners on the rear side of the second pole piece 220 along the conveying direction are respectively located in the shooting ranges 133 of the two second cameras 1312, and are used for re-photographing and detecting after the deviation rectifying adjustment of the second pole piece 220. Specifically, the first cameras 1311 first photograph and detect the two corners on the front side of the second pole piece 220 along the conveying direction. The deviation rectifying assembly rectifies and adjusts the position of the second pole piece 220 to align with the standard position. Then, the two corners on the rear side of the second pole piece 220 along the conveying direction are re-photographed and detected by the second cameras 1312 to confirm that the second pole piece 220 is accurately aligned with the standard position 400 under the adjustment of the deviation rectifying assembly. Finally, the second pole piece 220 is conveyed onto the feeding tape 200a to ensure the accurate feeding of the second pole piece 220 and ensure that the position of the second pole piece 220 is aligned with that of the first pole piece 230 on the feeding tape 200a, thereby ensuring the quality of the composite tape 200b obtained after thermal lamination.

[0042] In one embodiment, the vision recognition assembly 130 further includes a shooting light source 132. The vision camera 131 and the shooting light source 132 are placed inside the housing of the feeding assembly 110, and the vision camera 131 and the shooting light source 132 are arranged at intervals to form a gap for the second pole piece 220 to pass through. Since in the actual device, the space for conveying the second pole piece 220 inside the housing of the feeding assembly 110 is small, the internal space of the housing is relatively dark. By providing the shooting light source 132 inside the housing, the clarity of the photograph taken by the vision camera 131 is ensured, and the accuracy of vision recognition detection is improved.

[0043] In one embodiment, the feeding assembly 110 further includes a machine body and a first driving member (not shown). The feeding table 122 is movably arranged on the machine body, and the first driving member drives the feeding table 122 to move to convey the second pole piece 220 onto the feeding tape 200a. Among them, the first driving member drives the feeding table 122 to move on the machine body to realize conveying the second pole piece 220 on the feeding table 122 onto the feeding tape 200a and complete the feeding operation of the second pole piece 220.

[0044] In one embodiment, the feeding assembly 110 further includes a second driving member (not shown) and a feeding clamp 125. The feeding clamp 125 is disposed between the feeding table 122 and the feeding tape 200a. The second driving member drives the feeding clamp 125 to clamp or release the second pole piece 220, so as to convey the second pole piece 220 placed on the feeding table 122 onto the feeding tape 200a. Specifically, the feeding clamp 125 includes a first clamping plate and a second clamping plate. Through the clamping and supporting of the first clamping plate and the second clamping plate, the second pole piece 220 falls smoothly and flatly onto the feeding tape 200a, ensuring the flatness of the second pole piece 220 and the alignment with the corresponding position of the feeding tape 200a, thereby ensuring the quality of the composite tape 200b obtained after thermal lamination.

[0045] In the present utility model, the first driving member and the second driving member can adopt driving devices and structures such as motors, cylinders or hydraulic cylinders, as long as they can achieve the above driving actions of the present utility model, and no specific limitations are made in the present utility model.

[0046] In actual operation, the first deviation rectifying member 121 includes a first deviation rectifying motor 1211 for driving the feeding table 122 to move along the first deviation rectifying direction 310, the second deviation rectifying member 123 includes a second deviation rectifying motor 1231 for driving the feeding table 122 to move along the second deviation rectifying direction 320, and the third deviation rectifying member 124 includes a third deviation rectifying motor 1241 for driving the feeding table 122 to move along the third deviation rectifying direction 330.

[0047] Specifically, the connection positions of the second deviation rectifying motor 1231 and the third deviation rectifying motor 1241 with the feeding table 122 are symmetrically arranged with respect to the central axis of the feeding table 122 perpendicular to the first deviation rectifying direction 310. During the deviation rectifying operation, the specific deviation rectifying operations of the deviation rectifying assembly are as Figures 3 to 7 shown, where as Figure 3 shown, only driven by the first deviation rectifying motor 1211, the feeding table 122 moves along the X direction 340 parallel to the first deviation rectifying direction 310 to rectify the feeding table 122 to the standard position 400; as Figure 4 shown, driven by the second deviation rectifying motor 1231 and the third deviation rectifying motor 1241 and with the same driving direction and driving amount, the feeding table 122 moves along the Y direction 350 parallel to the second deviation rectifying direction 320 and the third deviation rectifying direction 330 to rectify the feeding table 122 to the standard position 400; as Figure 5 shown, driven by the second deviation rectifying motor 1231 and the third deviation rectifying motor 1241 but with different driving amounts or opposite driving directions, the feeding table 122 rotates around its platform center 1221; as Figure 6As shown, the first deviation rectifying motor 1211 drives, and at the same time, the second deviation rectifying motor 1231 and the third deviation rectifying motor 1241 drive synchronously and have the same driving direction and driving amount, and the feeding table 122 moves along its diagonal direction to rectify the feeding table 122 to the standard position 400; As Figure 7 shown, the first deviation rectifying motor 1211, the second deviation rectifying motor 1231 and the third deviation rectifying motor 1241 drive simultaneously, and the driving amounts of the second deviation rectifying motor 1231 and the third deviation rectifying motor 1241 are different, and the feeding table 122 rotates around any point 1222 of the platform to rectify the feeding table 122 to the standard position 400.

[0048] In one embodiment, it further includes a feeding guiding assembly. The feeding guiding assembly is arranged at the discharging end of the feeding assembly 110. The feeding guiding assembly includes a first feeding roller 140 and a second feeding roller 150. The first feeding roller 140 and the second feeding roller 150 are respectively arranged on both sides of the feeding tape 200a in the thickness direction. Among them, the rotation directions of the first feeding roller 140 and the second feeding roller 150 are opposite to send the second pole piece 220 located between the first feeding roller 140 and the second feeding roller 150 onto the feeding tape 200a and fit it with the separator tape 210 on the surface of the feeding tape 200a.

[0049] Furthermore, the feeding assembly 110 includes a first feeder and a second feeder. The first feeder and the second feeder are respectively arranged on both sides of the feeding tape 200a. The first feeder and the second feeder respectively convey the second pole piece 220 towards the direction of the first feeding roller 140, and the second feeder conveys the second pole piece 220 towards the direction of the second feeding roller 150, so that the second pole piece 220 is respectively input from both sides of the feeding tape 200a in the thickness direction and fits on the surface of the separator tape 210 of the feeding tape 200a.

[0050] On the other hand, as Figures 1 to 11 shown, a pole piece thermal compounding device is further provided, which includes a frame 1 and the above-mentioned thermal compounding pole piece adjusting mechanism. The thermal compounding pole piece adjusting mechanism is installed on the frame 1.

[0051] In one embodiment, a thermal compounding assembly is further arranged on the frame 1. The thermal compounding assembly includes a first thermal compounding roller 160 and a second thermal compounding roller 170 with opposite rotation directions. The first thermal compounding roller 160 and the second thermal compounding roller 170 are respectively arranged on both sides of the feeding tape 200a in the thickness direction to realize the thermal compounding of the second pole pieces 220 on both sides of the feeding tape 200a in the thickness direction with the feeding tape 200a, and finally form a compound tape 200b for output, completing the thermal compounding processing operation of the pole pieces.
