Description

Technical Field

[0001] This application belongs to the technical field of lithium battery production equipment. Specifically, this application relates to a tape feeding device. Background Art

[0002] During the production process of lithium batteries, the electrode sheets and diaphragms (collectively referred to as tapes below) are all fed in the form of tape reels. It is necessary to fix the tape reel through a unwinding mechanism and release the tape at a predetermined speed. Then the tape is guided and output through a transmission roller. During the transmission process, the tape may slip to one side, resulting in problems such as position deviation, which affects the production of lithium batteries.

[0003] In the existing tape feeding device, one end of the transmission roller and the feeding mechanism are jointly installed on a vertically arranged mounting plate, and the other end of the transmission roller is suspended. This installation method has high requirements for the installation accuracy of each transmission roller. If there is an installation angle error between the transmission roller and the mounting plate, it is easy to cause the tape to deviate during the guiding and conveying process of the tape. The existing deviation correction method is to adjust the angle of one end of the idler roller through a cylinder to achieve the purpose of deviation correction. This deviation correction method has a slow response speed of the tape and low deviation correction efficiency. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, this application provides a tape feeding device to ensure that when the tape transmission deviates, it can be corrected in time.

[0005] To solve the above problems, the technical solutions adopted in this application are as follows:

[0006] An example of this application provides a tape feeding device, which includes a support frame, a driving part, a mounting frame, a transmission assembly and a tape position sensor. Among them: the transmission assembly is fixedly installed on the mounting frame, and the transmission assembly is used to transmit the tape in the first direction; the tape position sensor is arranged on the support frame, and the tape position sensor is located at the output end of the transmission assembly and close to the edge of the tape. The tape position sensor is used to detect the position information of the tape edge; the mounting frame is movably arranged on the support frame; the fixed end of the driving part is fixedly installed on the support frame, and the driving end of the driving part drives the mounting frame to move in the second direction according to the position information of the tape edge, and the second direction is perpendicular to the first direction.

[0007] The tape feeding device provided by the present application detects the edge position information of the tape being transported along the first direction through a tape position sensor, thereby determining whether the transportation of the tape deviates to one side. And when deviation occurs, the driving part can be used to drive the mounting rack to move along the second direction on the support frame, and further drive the transmission component arranged on the mounting rack to move along the second direction to achieve deviation correction. This way of driving the entire transmission component to move through the mounting rack to achieve deviation correction has better stability of each functional module in the transmission component, higher deviation correction accuracy, and fast deviation correction response speed.

[0008] According to some examples of the present application, a slide rail extending along the second direction is provided on the support frame, and the mounting rack is slidably arranged on the slide rail.

[0009] In the structural cooperation form of slidably arranging the mounting rack on the slide rail, the mounting rack can obtain relatively stable support and is easy to be driven to slide.

[0010] According to some examples of the present application, the driving part includes a first driving motor, a lead screw, and a driving connection part. The lead screw is arranged on the support frame and extends along the second direction, and the lead screw is driven by the first driving motor to rotate. The driving connection part is threadedly engaged with the lead screw and is connected to the mounting rack.

[0011] By driving the lead screw to rotate through the first motor, and then driving the driving connection part to step along the second direction, thereby driving the mounting rack to move along the second direction. The way of threaded engagement between the lead screw and the driving connection part is beneficial to achieving high-precision stepping, and the deviation correction accuracy is thus improved.

[0012] According to some examples of the present application, the mounting rack includes a connecting plate and two mounting plates. The two mounting plates are arranged on opposite sides of the transmission component along the second direction, and both ends of the connecting plate are fixedly connected to the two mounting plates respectively, and the driving end of the driving part is in transmission connection with the connecting plate.

[0013] The two mounting plates are distributed on opposite sides of the transmission component and are respectively fixedly connected to both ends of the connecting plate, which helps to improve the stable support for the transmission component, and the overall driving movement of the mounting rack can be realized by means of the transmission action of the driving end on the connecting plate.

[0014] According to some examples of the present application, the tape feeding device further includes a unwinding mechanism. The unwinding mechanism includes a base, a sliding seat, a second driving motor, an air shaft, and a third driving motor. The base is arranged on the support frame, the sliding seat is slidably arranged on the base and is driven by the second driving motor to move along the second direction. The air shaft is arranged on the sliding seat and supports the tape roll, and the third driving motor drives the air shaft to rotate to release the tape from the tape roll.

[0015] The sliding seat is slidably arranged on the base and moves along the second direction under the drive of the second driving motor, thereby driving the air shaft to move, so as to correct the position of the tape reel in the second direction, that is, to ensure that the transmission direction of the tape released from the tape reel is corrected.

[0016] According to some examples of the present application, the transmission assembly includes a plurality of transmission rollers, and adjacent transmission rollers are arranged in a staggered manner in the vertical direction.

[0017] The transmission rollers are arranged in a staggered manner in the vertical direction to avoid the straight-up or straight-down transmission of the tape, which helps to prevent the ear from folding during the tape transmission.

[0018] According to some examples of the present application, the transmission assembly further includes a tension control mechanism, which includes a cylinder, a rotating shaft and a tension adjusting transmission roller. The cylinder is arranged on the mounting frame, the rotating shaft is rotatably arranged on the mounting frame and is driven by the cylinder to rotate. Both ends of the tension adjusting transmission roller are connected to the rotating shaft, and when the rotating shaft is driven to rotate, the tension adjusting transmission roller swings to adjust the tension of the tape passing over the tension adjusting transmission roller.

[0019] During the conveying process of the tape, the cylinder is used to drive the rotating shaft to drive the tension adjusting transmission roller to swing, thereby realizing the tension control of the tape.

[0020] According to some examples of the present application, the transmission assembly further includes a tape buffer mechanism, which includes a fixed seat, a lifting frame, a lifting motor and a buffer adjusting transmission roller. The fixed seat is installed on the mounting frame, the lifting frame is movably arranged on the fixed seat along the vertical direction, the lifting motor is installed on the fixed seat, the driving end of the lifting motor is connected to the lifting frame to drive the lifting frame to lift in the vertical direction, and the buffer adjusting transmission roller is installed on the lifting frame. The vertical lifting can adjust the length of the tape located in the transmission assembly.

[0021] Driving the lifting frame to lift or lower along the vertical direction on the fixed seat drives the lifting of the buffer adjusting roller, and then the length of the tape passing through the transmission roller can be adjusted, so as to realize the buffering of the tape.

[0022] According to some examples of the present application, the tape feeding device further includes an auxiliary driving roller, which is arranged on the support frame and adjacent to the output end of the transmission assembly, and the auxiliary driving roller drives the tape to provide the conveying power along the first direction.

[0023] Setting the auxiliary driving roller to drive the tape to provide the conveying power along the first direction can prevent the tape from slipping due to the too long transmission interval.

[0024] According to some examples of the present application, the tape feeding device further includes two sets of dust removal components. The two sets of dust removal components are both fixedly installed on the mounting frame, and the two sets of dust removal components are arranged in a staggered manner in the vertical direction and are respectively close to the upper surface and the lower surface of the tape to remove impurities on the tape.

[0025] By using the dust removal components arranged in a staggered manner, impurities such as dust on the upper surface and the lower surface of the tape are removed.

[0026] According to some examples of the present application, the dust removal component includes a plasma generation part, a blowing part, and a dust suction part. The plasma generation part, the blowing part, and the dust suction part are independent of each other. The plasma generation part and the blowing part are located between the two dust suction parts. The plasma generation part is used to generate a plasma flow towards the surface of the tape. The blowing part has a blowing cavity, and the airflow generated through the blowing cavity blows the plasma flow towards the surface of the tape. The dust suction part is used to suck the impurities blown off from the surface of the tape.

[0027] The plasma generation part, the blowing part, and the dust suction part are independent of each other. This split structure facilitates adjusting the spatial positions and relative distances of the plasma generation part, the blowing part, and the dust suction part when assembling the dust removal component, so as to ensure that the plasma flow can act on the surface of the tape, and thus a better dust removal effect is produced.

[0049] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0050] Such as Figure 1 , Figure 2 And Figure 3As shown, an example of the present application provides a tape feeding device. The tape feeding device includes a support frame 1, a driving part 2, a mounting frame 3, a transmission assembly 4, and a tape position sensor 5, where: The support frame 1 serves as the main frame of the tape feeding device, mainly providing an installation and support foundation for relevant structural components; The mounting frame 3 is arranged on the support frame 1, and the mounting frame 3 can move on the support frame 1 when driven; The transmission assembly 4 is fixedly installed on the mounting frame 3 to move along with the mounting frame 3, and the transmission assembly 4 is used to transmit the tape 8. After the tape 8 is released from the tape roll, it is continuously transmitted by the transmission assembly 4 along the first direction. Here, the first direction can be understood as the length direction of the continuously transmitted tape 8; The tape position sensor 5 is arranged on the support frame 1, and the tape position sensor 5 is located at the output end of the transmission assembly 4 and close to the edges on both sides of the tape 8. The tape position sensor 5 is used to detect the position information of the edges of the tape 8; The driving part 2 has a fixed end and a driving end. The fixed end is fixedly installed on the support frame 1, and the driving end drives the mounting frame 3 to move along the second direction according to the position information of the edges of the tape 8. The second direction is perpendicular to the first direction. Here, the second direction can also be understood as the width direction of the continuously transmitted tape 8.

[0051] In this embodiment, the tape feeding device detects the position information of the edges on both sides of the tape 8 through the tape position sensor 5 to judge whether the transmission of the tape 8 deviates to one side. When the tape 8 deviates, the driving part 2 drives the mounting frame 3 to move along the second direction on the support frame 1, and then drives the transmission assembly 4 arranged on the mounting frame 3 to move along the second direction to the other side opposite to the deviation direction. Through this movement, the deviation correction of the tape 8 transmission can be realized. In this embodiment, the way of realizing deviation correction by driving the entire transmission assembly 4 to move through the mounting frame 3 has better stability of each functional module in the transmission assembly 4, higher deviation correction accuracy, and faster deviation correction response speed.

[0052] Refer to Figure 4 And in combination with Figures 1 to 3 As shown, in some embodiments, a slide rail 11 is arranged on the support frame 1. The slide rail 11 extends along the second direction and thus has a certain length dimension in the second direction. The mounting frame 3 is slidably arranged on the slide rail 11 through a slider. This sliding arrangement structure and matching form enable the mounting frame 3 to be conveniently driven and move along the second direction on the slide rail 11, and the mounting frame 3 also obtains relatively stable support accordingly.

[0053] Continue to refer to Figure 4 And in combination with Figures 1 to 3As shown, in some embodiments, the driving unit 2 includes a first driving motor 21, a lead screw 22 and a driving connection part 23. The lead screw 22 is arranged on the support frame 1 and extends along the second direction and has a certain length dimension, and the lead screw 22 is driven by the first driving motor 21 to rotate around its own central axis. The driving connection part 23 is threadedly arranged on the lead screw 22, and the driving connection part 23 also serves as the driving end of the driving unit 2 to drive the mounting frame 3. For this reason, the driving connection part 23 is also connected to the mounting frame 3. The rotation of the lead screw 22 driven by the first motor can drive the driving connection part 23 to translate along the second direction on the lead screw 22. The driving connection part 23 drives the mounting frame 3 to move along the second direction. In this embodiment, the threaded cooperation between the lead screw 22 and the driving connection part 23 is conducive to achieving high-precision translation, and the accuracy of correction is also improved.

[0054] Continue to refer to Figure 4 Combined with Figures 1 to 3 As shown, in one embodiment, the mounting frame 3 includes a connecting plate 32 and two mounting plates 31, the mounting plate 31 has a vertical plane parallel to the vertical direction, the vertical plane is convenient for installing the transmission component 4, the two mounting plates 31 are spaced apart along the second direction so that the two vertical planes are opposite, and the two mounting plates 31 are located on the opposite sides of the transmission component 4 to jointly support the transmission component 4, thereby improving the stability of the support for the transmission component 4, the two ends of the connecting plate 32 are respectively fixedly connected to the two mounting plates 31, and the driving end of the driving part 2 is transmission-connected to the upper end of the connecting plate 32, and the overall driven movement of the mounting frame 3 can be realized by means of the transmission action of the driving end on the connecting plate 32.

[0055] Back to Figure 3 As shown, in some embodiments of the present application, the transmission component 4 includes a plurality of transmission rollers 41, and adjacent transmission rollers 41 are staggered in the vertical direction. The transmission rollers 41 at adjacent positions have different heights in the vertical direction, and are spaced apart in the first direction. The transmission rollers 41 at adjacent positions are provided with a predetermined spacing distance in the first direction, thereby avoiding the straight-up or straight-down transmission of the material strip 8 to prevent the tabs of the material strip 8 from folding during the transmission process.

[0056] Reference Figure 5 Combined with Figures 1 to 3As shown, in some embodiments of the present application, the transmission component 4 further includes a tension control mechanism 42. The tension control mechanism 42 includes a cylinder 421, a rotating shaft 422, and a tension adjusting transmission roller 423. The fixed end of the cylinder 421 is arranged on the mounting bracket 3. The rotating shaft 422 is rotatably arranged on the mounting bracket 3 and is driven to rotate by the driving end of the cylinder 421. Both mounting ends of the tension adjusting transmission roller 423 are connected to the rotating shaft 422. And the roller surface of the tension adjusting transmission roller 423 is used to abut against the surface of the material tape 8 and rotates due to friction as the material tape 8 is transmitted. And when the rotating shaft 422 is driven to rotate, the tension adjusting transmission roller 423 swings to tension or loosen the material tape 8 passing over the tension adjusting transmission roller 423, thereby adjusting the tension of the material tape 8. Therefore, in the process of conveying the material tape 8 in this embodiment, the cylinder 421 can be used at any time to drive the rotating shaft 422 to drive the tension adjusting transmission roller 423 to swing, thereby realizing the tension control of the material tape 8.

[0057] In this embodiment, the rotating shaft 422 can be connected to the cylinder 421 through a driving arm. Specifically, one end of the driving arm is connected to the rotating shaft 422, and the other end is driven by the telescopic end of the cylinder 421. The telescopic end is used to make the driving arm rotate, and then drive the rotating shaft 422 to rotate, so as to drive the tension adjusting transmission roller 423 to swing.

[0058] Continue to refer to Figure 5 As shown, in specific implementation, one end of the rotating shaft 422 is rotatably connected to a fixed mounting block 424, and the other end is rotatably connected to an angle adjusting mounting block 425. The fixed mounting block 424 is fixedly arranged on the mounting bracket 3, while the angle adjusting mounting block 425 is movably arranged on the mounting bracket 3. The angle adjusting mounting block 425 has a horizontal mounting hole along the first direction and a vertical mounting hole along the vertical direction. And the mounting bracket 3 is equipped with a first set screw and a second set screw. The first set screw is in threaded cooperation with the horizontal mounting hole, and the second set screw is in threaded cooperation with the vertical mounting hole. The angle formed by the tension adjusting transmission roller 423 and the first direction can be adjusted by adjusting the first set screw, and the angle formed by the tension adjusting transmission roller 423 and the vertical direction can be adjusted by adjusting the second set screw. Through these two angle adjustments, the tension adjusting transmission roller 423 can be better fitted to the surface of the material tape 8. For this embodiment, when the angle of the tension adjusting transmission roller 423 needs to be adjusted, adjust the first set screw and / or the second set screw. After the angle of the tension adjusting transmission roller 423 is in place, then tighten the set screw. This structure is easy to realize the adjustment of the installation position of the tension adjusting transmission roller 423 and has a low cost.

[0059] Refer to Figure 6 And in combination with Figures 1 to 3As shown, in some embodiments of the present application, the transmission assembly 4 further includes a tape buffer mechanism 43, which includes a fixed seat 431, a lifting frame 432, a lifting motor 433, and a buffer adjustment transmission roller 434. Among them, the fixed seat 431 is installed on the mounting frame 3. For example, both ends of the fixed seat 431 are fixedly installed on a mounting plate 31, and the two mounting plates 31 jointly support the fixed seat 431 to make the structure of the tape buffer mechanism 43 more stable. The lifting frame 432 is arranged on the fixed seat 431, and the lifting frame 432 is movable along the vertical direction on the fixed seat 431. The lifting motor 433 is installed on the fixed seat 431, and the driving end of the lifting motor 433 is connected to the lifting frame 432 to drive the lifting frame 432 to lift in the vertical direction. The buffer adjustment transmission roller 434 is installed on the lifting frame 432, and the tape 8 always passes through and contacts the buffer adjustment transmission roller 434 and then is transmitted to the output end. The lifting of the buffer adjustment transmission roller 434 along the vertical direction can adjust the length of the tape 8 located in the transmission assembly 4. Specifically, driving the lifting frame 432 to lift along the vertical direction on the fixed seat 431 drives the lifting of the buffer adjustment roller, and thus the length of the tape 8 passing through the transmission roller 41 can be adjusted to achieve the buffering of the tape 8. In some embodiments of the present application, the fixed end of the lifting motor 433 is installed on the connecting plate 32. While the driving end of the driving part 2 drives the entire mounting frame 3 to translate through the connecting plate 32, it also synchronously drives the tape buffer mechanism 43 to perform an overall translation.

[0060] Back to Figure 3 As shown, in some instances, the tape feeding device further includes an auxiliary driving roller 44. The auxiliary driving roller 44 is arranged on the support frame 1 and near the output end of the transmission assembly 4. The auxiliary driving roller 44 drives the tape 8 to provide the conveying power in the first direction. Due to the arrangement of the auxiliary driving roller 44, the tape 8 can avoid the slipping phenomenon caused by too long a transmission interval.

[0061] It should be noted that, such as the buffer adjustment transmission roller 434 involved in the tape buffer mechanism 43, the tension adjustment transmission roller 423 involved in the tension adjustment control mechanism, and the auxiliary driving roller 44 can be understood as components of the multiple transmission rollers 41 described above.

[0062] Referring to Figure 7 And in combination with Figures 1 to 3As shown, when the tape feeding device described above is implemented specifically, it further includes an unwinding mechanism 6. The unwinding mechanism 6 includes a base 61, a sliding seat 62, a second driving motor 63, an air shaft 64, and a third driving motor 65. The base 61 is disposed on the support frame 1 and a guide rail 66 is formed on the base 61. The sliding seat 62 is slidably disposed on the guide rail 66 and is driven by the second driving motor 63 to move along the second direction. The air shaft 64 that can tension and loosen the tape roll from the center of the tape roll is disposed on the sliding seat 62 and supports the tape roll. For this reason, the movement of the sliding seat 62 can drive the air shaft 64 to move, so that the position of the tape roll can be corrected in the second direction. The third driving motor 65 drives the air shaft 64 to rotate to continuously release the tape 8 from the tape roll to the transmission assembly 4. This embodiment can timely correct the transmission direction of the tape 8 released from the tape roll, and can facilitate the synchronous movement of the unwinding mechanism 6 and the mounting frame 3, improving the deviation correction effect.

[0063] Referring to Figures 8 to 11 and in combination with Figures 1 to 3 As shown, in some embodiments, the tape feeding device further includes two dust removal assemblies 7. The two dust removal assemblies 7 are both fixedly installed on the mounting frame 3, and the two dust removal assemblies 7 are arranged in a staggered manner in the vertical direction and are respectively close to the upper surface and the lower surface of the tape 8 to remove impurities on the upper surface and the lower surface of the tape 8.

[0064] Continuing to refer to Figures 8 to 11 , the dust removal assembly 7 includes a dust removal part 71 and a dust suction part 72. The dust removal part 71 includes a plasma generation part 711 and a blowing part 712. The plasma generation part 711, the blowing part 712, and the dust suction part 72 are independent of each other and arranged side by side. The plasma generation part 711 and the blowing part 712 are located between the two dust suction parts 72. The plasma generation part 711 is used to generate a plasma flow toward the surface of the tape 8. The blowing part 712 has a blowing cavity (such as Figure 9 the slit shown). And the air flow generated through the blowing cavity blows the plasma flow toward the surface of the tape 8 to blow off the impurities on the tape. The dust suction part 72 sucks the impurities blown off from the surface of the tape 8 through the dust suction port.

[0065] As a beneficial improvement and attempt, the dust suction port can be designed to be an elongated slit shape to increase the wind pressure at the dust suction port. On this basis, the extending trajectory of the dust suction port can be selected as a straight line type, a curve type, or a broken line type, as Figure 9 shown. Among these structural forms of the dust suction port, the broken line type can increase the relative area of dust suction, and the elongated design can increase the suction force.

[0066] In this embodiment, the plasma generating unit 711, the air blowing unit 712, and the dust suction unit 72 are independent of each other. This split structure facilitates adjusting the spatial positions and relative distances of the plasma generating unit 711, the air blowing unit 712, and the dust suction unit 72 when assembling the dust removal assembly 7, so as to ensure that the plasma flow can act on the surface of the strip 8, thereby achieving a better dust removal effect. When one of the components is damaged, it is convenient to replace, reducing the maintenance cost of the equipment. In order to control the distance between the dust removal unit 71 and the dust suction unit 72, the dust suction unit 72 and the dust removal unit 71 have a lateral spacing measured in the side-by-side direction and the lateral spacing is adjustable. For example, an oblong hole can be provided on the mounting plate (thus having a certain length dimension). In this way, by adjusting the mounting positions of the dust suction unit 72 and the dust removal unit 71 on the mounting plate in the length dimension direction of the oblong hole, the lateral spacing between the dust suction unit 72 and the dust removal unit 71 can be adjusted.

[0067] In this embodiment, the air blowing unit 712 is formed with a receiving groove, and the plasma generating unit 711 is installed in the receiving groove of the air blowing unit 712 through a mounting block. Considering the length and width of the electrode plate, the receiving groove can be designed to be strip-shaped, and the plasma generating unit 711 can include ion rods. Therefore, the ion rods are arranged along the length direction of the receiving groove, as Figure 10 and Figure 11 shown.

[0068] In this embodiment, the dust removal unit 71 further includes a base. The base has a cavity that penetrates in the vertical direction. Both ends of the base are connected with fixing plates 74, and the fixing plates 74 at both ends are arranged on the mounting rack 3 through height adjusting members 75. The height (distance) of the dust removal unit 71 relative to the strip 8 can be adjusted through the height adjusting members 75. The plasma generating unit 711 is arranged in the penetrating cavity, and the air blowing unit 712 is arranged on two opposite side walls of the cavity. The air blowing unit 712 can be an air blowing cavity (slit) provided on the side wall. The plasma flow generated by the plasma generating unit 711 is blown onto the surface of the strip 8 through the air blowing cavity (slit). Moreover, in this embodiment, dust suction units 72 are connected to both outer sides of the base. At least on the outer side of one dust suction unit 72, a magnetic adsorption part 73 is provided. The magnetic adsorption part 73 is detachably installed on the side of the dust suction unit 72 away from the dust removal unit 71 through a mounting groove. The magnetic adsorption part 73 is used to adsorb iron impurities on the strip 8. Optionally, an oblong hole is provided on the mounting groove, and the mounting groove is installed on the side of the dust removal unit 71 in a height-adjustable manner through the oblong hole.
