Description

Technical Field

[0001] This invention relates to the field of electrode production equipment technology, and in particular to a conveying device, a correction method, and an adhesive application device. Background Technology

[0002] The adhesive applicator applies adhesive to both sides of the foil, then coats the foil with an electrode layer to form an electrode sheet. Finally, the adhesive tape is peeled off the foil, leaving blank areas arranged along the width of the electrode sheet for subsequent tab formation.

[0003] However, when the drive roller rotates at a high speed, the electrode sheet is prone to shifting, or when the conveyor roller tilts, the tension on both sides of the foil is inconsistent. The side with greater foil tension will shift towards the side with less foil tension. Unlike the overall shift of the foil, one side of the foil will not move, or the displacement of the two sides will be different. In this case, wrinkles may appear on the surface of the foil.

[0004] The above problems cannot be solved by using conventional correction devices to correct the overall alignment of the foil. Furthermore, when the foil is wrinkled, the tape is difficult to adhere to the pre-set adhesive position on the foil surface, and the tape on both sides of the foil is difficult to keep overlapping, which affects the adhesive application and leads to the scrapping of the electrode sheet.

[0005] In addition, multiple tapes arranged along the width of the foil are usually applied to one side of the foil surface. Even if the position of the tapes can be adjusted, the spacing between the tapes arranged along the width of the foil will increase after the foil is finished being applied and has returned to a relaxed state. Summary of the Invention

[0006] To solve at least one of the above-mentioned technical problems, the present invention provides a conveying device, a correction method, and an adhesive application device, the technical solutions of which are as follows.

[0007] The adhesive applicator provided by the present invention includes a conveying device, a first feeding roller and a second feeding roller, wherein the first feeding roller is used to provide foil material and the second feeding roller is used to provide adhesive tape to be applied to the foil material.

[0008] The conveying device provided by the present invention includes a conveying component and an adjusting component. The conveying component includes a conveying roller, which rolls and conveys foil in a wrapping manner. The adjusting component includes an adjusting roller and a moving component. The moving component is respectively provided at both ends of the adjusting roller. The adjusting roller wraps around the foil and tensions the foil in a first direction. The moving component drives the end of the adjusting roller to move in the first direction or drives the end of the adjusting roller to move in the opposite direction in the first direction, so that one end of the adjusting roller is inclined relative to the other end.

[0009] In some embodiments of the present invention, the moving assembly includes a first mounting base, a first driver, and a first moving component. The end of the adjusting roller is rotatably connected to the first moving component. The first moving component is connected to the first driver, and the first driver is connected to the first mounting base. The first driver drives the first moving component to move in a first direction or drives the first moving component to move in the opposite direction of the first direction.

[0010] In some embodiments of the present invention, the first driver includes a pushing component connected to the first moving component, and a pressure sensor is disposed between the pushing component and the first moving component.

[0011] In some embodiments of the present invention, the first driver includes a rotary drive member, the first driver drives the first moving part to move in a helical transmission manner, the output end of the first driver is provided with a transmission rod, the transmission rod is provided with an external thread, the first moving part is provided with an internal thread structure, and the transmission rod is threadedly connected to the internal thread structure.

[0012] In some embodiments of the present invention, the conveying device includes an image acquisition component and a control component, the image acquisition component being electrically connected to the control component, the image acquisition component acquiring an image of the foil wrapped around the conveying roller and transmitting it back to the control component, and the control component determining whether the surface of the foil is wrinkled.

[0013] In some embodiments of the present invention, the conveying device includes a pressing assembly, the pressing assembly including at least one pressing roller, the pressing roller and the conveying roller respectively rolling in contact with opposite sides of the foil surface; when at least two pressing rollers are provided, each pressing roller is spaced apart along the axial direction of the conveying roller.

[0014] In some embodiments of the present invention, the position of the pressing roller is adjustable along the axial direction of the conveying roller.

[0015] The present invention provides a method for correcting the deviation of foil material conveyed in a conveying device. The conveying device includes a conveying component and an adjusting component. The conveying component includes a conveying roller, and the adjusting component includes an adjusting roller and a moving component. The moving component is respectively provided at both ends of the adjusting roller. The adjusting roller is wound around the foil material and tensions the foil material along a first direction. The method for correcting the deviation includes the following working process: when one side of the foil material is slack and the other side is tensioned, the end of the adjusting roller near the slack side of the foil material is driven by the moving component, and that end of the adjusting roller moves along the first direction to tension the slack side of the foil material.

[0016] In some embodiments of the present invention, when one side of the foil is relaxed and the other side is tensioned, the other end of the adjusting roller moves in the opposite direction along the first direction under the drive of the moving component.

[0017] The embodiments of the present invention have at least the following beneficial effects: In the conveying device, when the foil material is loose on one side and overly tense on the other side, the moving component drives the adjusting roller to tilt, so that one end of the adjusting roller further tensions the loose side of the foil material, and the other end of the adjusting roller reduces the tension, thereby balancing the tension of the foil material, avoiding wrinkles on the surface of the foil material, and ensuring good adhesive application effect.

[0036] The following is combined Figures 1 to 6 Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this invention, it should be understood that the use of terms such as "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] This invention relates to an adhesive application apparatus, which includes a conveying device, a first feed roller, and a second feed roller. The first feed roller provides foil, and the second feed roller provides adhesive tape to be applied to the foil. Specifically, the first feed roller provides foil to the conveying device, and the second feed roller provides adhesive tape to the conveying device; the foil and adhesive tape are then laminated within the conveying device.

[0040] Furthermore, the first feeding roller is connected to a motor to rotate, and the second feeding roller is connected to a motor to rotate.

[0041] The other components and operation of the adhesive application equipment are already described in the relevant art for those skilled in the art, and will not be described in detail here. The structure of the conveying device will be introduced below.

[0042] This invention relates to a conveying device, comprising a conveying assembly and an adjusting assembly 2000. The conveying assembly includes a conveying roller 1100, which is rotatable and rolls to convey foil in a wrapping manner. During conveying, the conveying roller 1100 presses and adheres adhesive tape to the foil. One side of the foil is wrapped around the roller surface of the conveying roller 1100, and the other side is adhered with adhesive. It is understood that during conveying, if the foil becomes wrinkled due to one side being loose and the other side being tense, the adjusting assembly 2000 can correct the foil's deviation to keep it flat and evenly tensioned during conveying.

[0043] Further, the adjusting assembly 2000 includes an adjusting roller 2100, which is rotatable and wraps around the foil material, tensioning the foil material along a first direction. Further, the adjusting assembly 2000 includes a moving assembly 2200, with moving assemblies 2200 respectively disposed at both ends of the adjusting roller 2100. Specifically, the moving assembly 2200 drives the end of the adjusting roller 2100 to move along the first direction, or the moving assembly 2200 drives the end of the adjusting roller 2100 to move in the opposite direction along the first direction, so that one end of the adjusting roller 2100 is inclined relative to the other end.

[0044] When the conveyor roller 1100 tilts, the foil surface experiences uneven stress, causing one side of the foil to become slack while the other side becomes over-tensioned. In this case, the over-tensioned side of the foil may shift towards the slack side, potentially causing wrinkles. Therefore, the adjusting roller 2100 is designed to adjust the tilt angle to regulate the tension of the foil surface. Specifically, after the moving component 2200 drives the adjusting roller 2100 to tilt, the adjusting roller 2100 can increase the tension on the slack side of the foil and decrease the tension on the over-tensioned side, thereby balancing the tension on the foil surface.

[0045] Referring to the accompanying drawings, during the conveying of foil, if the position of the conveying roller 1100 shifts, causing a relative tilt between the two conveying rollers 1100 (where the L-ends of the two rollers 1100 are closer together and the R-ends are farther apart), the tension of the foil at the R-end of the conveying roller 1100 will be greater. The side of the foil near the R-end of the conveying roller 1100 will shift towards the L-end, causing wrinkles in the foil. In this case, the L-end of the adjusting roller 2100 moves along the first direction, increasing the tension of the adjusting roller 2100 on the side of the foil near the L-end of the conveying roller 1100, thus balancing the tension on the foil surface. Of course, it is understood that the R-end of the adjusting roller 2100 can also be moved in the opposite direction along the first direction.

[0046] It is understandable that adhesive needs to be applied to both sides of the foil. Therefore, the conveying assembly is designed to include two conveying rollers 1100. The foil is wrapped around the two conveying rollers 1100 in sequence. Adhesive is applied to side A of the foil at one of the conveying rollers 1100 and adhesive is applied to side B of the foil at the other conveying roller 1100.

[0047] In one embodiment, the conveying assembly includes a tension roller 1300. Referring to the accompanying drawings, the conveying roller 1100 and the tension roller 1300 are arranged sequentially along the conveying direction of the foil, and the adjusting roller 2100 is located between the conveying roller 1100 and the tension roller 1300.

[0048] During the foil conveying process, if the first ends of the conveyor roller 1100 and the tension roller 1300 adjacent to the adjusting roller 2100 are inclined towards each other, resulting in a situation where the first ends of the conveyor roller 1100 and the tension roller 1300 are closer together and the second ends are farther apart, the parallelism between the conveyor roller 1100 and the tension roller 1300 will change, leading to foil tension imbalance, lateral position displacement, and surface wrinkles. In this case, the moving component 2200 drives the first end of the adjusting roller 2100 to move along the first direction, tilting the first end of the adjusting roller 2100 relative to the second end, so that the first end of the adjusting roller 2100 further tensions the foil, thereby ensuring that the surface tension of the foil tends to be balanced and avoiding foil wrinkles.

[0049] To facilitate the description and understanding of the technical solution, the first ends of the aforementioned conveying roller 1100, tensioning roller 1300, and adjusting roller 2100 are all the same end, and the second ends are all the other ends. The aforementioned correction process is for situations where the foil material is loose on the side near the first end of the conveying roller 1100 and over-tensioned on the side near the second end.

[0050] Regarding the setting of the adjusting roller 2100 and the tensioning roller 1300, as an alternative, the following design can also be made.

[0051] In some examples, the tension roller 1300 is located between the two conveyor rollers 1100 along the foil conveying direction. In this case, the adjusting roller 2100 is located in front of or behind the tension roller 1300. Alternatively, the tension roller 1300 and the two conveyor rollers 1100 are arranged sequentially. In this case, the adjusting roller 2100 is located behind the tension roller 1300.

[0052] In some examples, the adjusting roller 2100 is located between two conveying rollers 1100 along the conveying direction of the foil. In this case, when the first ends of the two conveying rollers 1100 are inclined towards each other, the parallelism between the two conveying rollers 1100 changes. The first end of the adjusting roller 2100 needs to move along the tensioning direction to further tension the loose side of the foil.

[0053] It should be noted that the first direction refers to the tensioning direction of the adjusting roller 2100 on the foil. Therefore, in different embodiments, if the position of the adjusting roller 2100 is different, the first direction may also be different.

[0054] In one embodiment, the conveying device includes an auxiliary component 1400, which is disposed at the tension roller 1300. The auxiliary component 1400 includes an auxiliary rolling element 1401, which rolls and contacts the opposite sides of the foil material with the tension roller 1300. The auxiliary rolling element 1401 is configured as a driven element; specifically, it is configured as a pressure roller or pressure wheel. It is understood that the auxiliary rolling element 1401 can position the foil material, reducing the possibility of overall foil misalignment.

[0055] Furthermore, the auxiliary component 1400 includes an encoder 1402, and an auxiliary roller 1401 is connected to the encoder 1402. It is understood that the encoder 1402 can detect the movement distance of the foil through the auxiliary roller 1401.

[0056] In one embodiment, the conveying device includes a pressing assembly 1200, which presses the tape and foil together to achieve adhesive application to the surface of the foil. It is understood that the pressing assembly 1200 is positioned corresponding to the conveying roller 1100, and when adhesive needs to be applied to both sides of the foil, two pressing assemblies 1200 are correspondingly provided.

[0057] Specifically, the pressing assembly 1200 includes a pressing roller 1201, with at least one pressing roller 1201. The pressing roller 1201 and the conveying roller 1100 respectively roll in contact with opposite sides of the foil surface to facilitate adhesive application. In some examples, the pressing roller 1201 is configured as a roller or pressure roller. It is understood that using the pressing roller 1201 to roll in contact with the foil can also prevent foil positional displacement, prevent foil surface wrinkling, and prevent the spacing between two adjacent adhesive strips from increasing as the foil relaxes after adhesive application.

[0058] In some examples, considering that there are multiple adhesive tapes on the foil, multiple pressing rollers 1201 are provided, and each pressing roller 1201 is distributed at intervals along the axial direction of the conveyor roller 1100.

[0059] In one embodiment, the position of the pressing roller 1201 is adjustable along the axial direction of the conveyor roller 1100 to adjust the position of the pressing roller 1201 according to the position of the tape on the foil.

[0060] Referring to the accompanying drawings, the pressing assembly 1200 includes a pressing mounting base 1202, a second moving component 1203, and a second guide structure 1204. The number of second moving components 1203 is the same as that of pressing rolling components 1201. The pressing rolling components 1201 are connected to the second moving components 1203. The second moving component 1203 is slidably connected to the second guide structure 1204. The second guide structure 1204 is connected to the pressing mounting base 1202. The second guide structure 1204 is arranged along the axial direction of the conveyor roller 1100. The second guide structure 1204 includes a guide rail. The second moving component 1203 is connected to the guide rail via a slider.

[0061] Furthermore, the pressing mounting base 1202 is provided with a scale, which is set along the axial direction of the conveyor roller 1100, so as to accurately adjust the position of the pressing rolling element 1201.

[0062] In some examples, each of the second moving parts 1203 is moved by a cylinder, and the operation of the cylinder is controlled by a pressure regulating valve. Furthermore, the pressure regulating valve is set as a solenoid valve.

[0063] Regarding the second guide structure 1204, as an alternative, it can also be designed as follows: In some examples, the second guide structure 1204 includes a guide rod, and the second moving part 1203 is provided with a linear bearing or bushing. In some examples, the second guide structure 1204 is configured as a groove recessed on the surface of the press-fit mounting base 1202.

[0064] In one embodiment, the conveying device includes a drive assembly, which includes a drive roller 1501 and a drive motor. The drive roller 1501 is connected to the drive motor, and the roller surface of the drive roller 1501 is wound around the side of the foil. The drive roller 1501 provides power for conveying the foil.

[0065] Furthermore, the drive assembly includes a drive roller 1502, which is configured as a driven member. The drive roller 1502 and the drive roller 1501 respectively roll in contact with opposite sides of the foil. It is understood that the pressure exerted by the drive roller 1502 on the sides of the foil can prevent the foil from slipping on the roller surface of the drive roller 1501.

[0066] In one implementation, the conveying device includes an image acquisition component 3100, which includes a camera and is capable of acquiring images of the adhesive tape on the side of the foil. It is understood that the conveying device includes a control component, and the image acquisition component 3100 is electrically connected to the control component. The images acquired by the image acquisition component 3100 are transmitted back to the control component, which is able to determine whether the adhesive tape is applied accurately.

[0067] Furthermore, to ensure clear image acquisition, the transmission device includes a light source assembly 3200 that illuminates the surface of the foil. In some examples, the illumination angle of the light source assembly 3200 is adjustable.

[0068] Specifically, when adhesive is applied to both sides of the foil, two image acquisition components 3100 are configured to acquire images of the adhesive on sides A and B of the foil respectively, and correspondingly, two light source components 3200 are configured.

[0069] Understandably, after adhesive is applied to side A of the foil, one image acquisition component 3100 acquires an image of the adhesive tape position on side A and returns it to the control component. After adhesive is applied to side B of the foil, another image acquisition component 3100 acquires an image of the adhesive tape position on side B and returns it to the control component. The control component compares the two acquired images to determine whether the adhesive tape positions on side A and side B of the foil correspond.

[0070] In one embodiment, the moving assembly 2200 includes a first driver 2202 and a first moving component 2203. The end of the adjusting roller 2100 is rotatably connected to the first moving component 2203, and the first moving component 2203 is connected to the first driver 2202. Specifically, the first driver 2202 drives the first moving component 2203 to move along a first direction to further increase the tension of the adjusting roller 2100 on the foil; or the first driver 2202 drives the first moving component 2203 to move in the opposite direction along the first direction to decrease the tension of the adjusting roller 2100 on the foil.

[0071] It is understood that the moving component 2200 includes a first mounting base 2201, and a first driver 2202 is connected to the first mounting base 2201. Further, the moving component 2200 includes a first guide structure, which is connected to the first mounting base 2201, and a first moving part 2203 is slidably connected to the first guide structure. Specifically, the first guide structure includes a guide rail or a guide rod, or the first guide structure is configured as a groove recessed into the surface of the first mounting base 2201.

[0072] In some examples, the first actuator 2202 includes a rotary drive element, which may include a motor, a rotary cylinder, or a rotary hydraulic cylinder. The first actuator 2202 drives the first moving part 2203 to move via a helical transmission. Specifically, the output end of the first actuator 2202 is provided with a transmission rod, the shaft of the rotary drive element is connected to the transmission rod via a coupling, the transmission rod is provided with an external thread, the transmission rod is configured as a screw, and the first moving part 2203 is provided with an internal thread structure, with the transmission rod threadedly connected to the internal thread structure.

[0073] Furthermore, the internal thread structure is configured as a threaded hole on the first moving part 2203, the threaded hole penetrating the first moving part 2203, and the transmission rod is threadedly connected to the inner wall of the threaded hole. It can be understood that the first driver 2202 drives the transmission rod to rotate, and the transmission rod drives the first moving part 2203 to move. In some examples, the first driver 2202 drives the first moving part 2203 via a ball screw pair.

[0074] Of course, as an alternative, the screw drive between the first driver 2202 and the first moving part 2203 can also be designed as follows: the slider with a threaded hole is used as the internal thread structure, the first moving part 2203 is connected to the slider, and the transmission rod passes through the slider and is threadedly connected to the slider.

[0075] Understandably, when the conveying device is equipped with an image acquisition component 3100, the image acquisition component 3100 acquires images of the foil wrapping around the conveyor roller 1100, and the control component can determine whether the surface of the foil is wrinkled, the direction of the foil's movement, and the tilt angle of the conveyor roller 1100. Specifically, when one side of the foil width shifts to the other side, causing the foil to wrinkle, the image acquisition component 3100 acquires image information of the positional changes of both sides of the foil on the conveyor roller 1100 and the tilt changes of the conveyor roller 1100. The control component can then determine the change in the foil's position through these images.

[0076] Furthermore, when there are two image acquisition components 3100, the images acquired by the two image acquisition components 3100 can not only be used by the control component to compare the position of the tape, but the control component can also analyze whether the surface of the foil is wrinkled in the image acquired by at least one of the image acquisition components 3100.

[0077] In some examples, the first actuator 2202 includes a pushing component connected to a first moving component 2203. The first actuator 2202 drives the first moving component 2203 to move along a first direction via the pushing component, thereby moving the end of the adjusting roller 2100. Specifically, the first actuator 2202 includes a cylinder or hydraulic cylinder, and the pushing component is configured as a push rod. Alternatively, the first actuator 2202 can be designed to include a motor with a telescopic rod, which acts as the pushing component.

[0078] Furthermore, the first actuator 2202 includes a pressure sensor. Specifically, a pressure sensor is disposed between the pushing component and the first moving component 2203. The pressure sensor is electrically connected to the control component, and the control component is capable of receiving signals from the pressure sensor. Specifically, the pressure sensor is configured as a pressure-sensitive sensor.

[0079] When the foil is over-tensioned on one side and slack on the other side, the control component can determine whether the foil is over-tensioned or slack by analyzing and comparing the pressure detected by the pressure sensors at both ends of the adjustment roller 2100. At this time, the end of the adjustment roller 2100 that is less affected by the foil reaction force moves along the first direction under the action of the moving component, further tightening the slack side of the foil.

[0080] Understandably, in some examples, it can be further designed that the end of the adjusting roller 2100 that is subjected to a greater reaction force from the foil moves in the opposite direction along the first direction under the action of the moving component, thereby reducing the force on the side of the foil that is overly tensioned.

[0081] The following describes the correction method of the present invention in detail with reference to specific embodiments. It should be noted that the following description is only illustrative and not a specific limitation of the present invention.

[0082] This invention relates to a method for correcting foil deviation during its transport in a conveying device. Specifically, the conveying device includes a conveying component and an adjusting component 2000. The conveying component includes a conveying roller 1100, and the adjusting component 2000 includes an adjusting roller 2100 and a moving component 2200. The adjusting roller 2100 has moving components 2200 at both ends, and the adjusting roller 2100 is wound around the foil and tensions the foil along a first direction.

[0083] The corrective measures include the following workflow.

[0084] With one side of the foil slack and the other side taut, the end of the adjusting roller 2100 near the slack side of the foil is moved in a first direction by the moving component 2200, so that the adjusting roller 2100 tilts, thereby tauting the slack side of the foil.

[0085] Furthermore, the other end of the adjusting roller 2100 moves in the opposite direction along the first direction under the drive of the moving component 2200, reducing the tension of the adjusting roller 2100 on the other side of the foil, so that the tension on the surface of the foil tends to be balanced.
