Description
Technical Field
[0001] This application relates to the field of correction device technology, and in particular to a pull-out strip anti-deviation interference device, an oven, and a coating machine. Background Technology
[0002] In existing industrial production, it is often necessary to carry out processes such as conveying, drying, and cutting of strip materials. For example, in the field of battery production, strip-shaped electrodes need to be transported, coated, and dried. Therefore, after the electrodes are coated, they need to be transported to an oven for drying. However, during the conveying process of the electrodes in the oven, due to the long travel distance and the turbulent flow of hot air inside the oven, the electrodes are prone to displacement. Once the displacement occurs, it is difficult to correct the problem, which in turn makes the drying position and effect of the electrodes uncontrollable. Utility Model Content
[0003] To address one of the aforementioned technical problems, this application provides a pull-out type strip anti-deviation interference device, including a base and a pressure roller assembly slidably disposed on the base. The pressure roller assembly is equipped with an upper pressure roller and a lower pressure roller for clamping and rolling contact with the strip. A displacement driving component is disposed on the base to drive the pressure roller assembly to move perpendicular to the width direction of the strip. During the strip conveying process, the upper and lower pressure rollers roll in cooperation with the strip. When the strip deviates in position, the displacement driving component drives the pressure roller assembly to move, which in turn moves the strip to correct the deviation. This achieves overall position adjustment of the strip, improves the positional accuracy during strip conveying, and enhances production quality.
[0004] Preferably, the pressure roller assembly includes a mounting base, and the upper pressure roller and the lower pressure roller are slidably disposed on the mounting base. The mounting base is provided with a lifting driver that drives the upper pressure roller and the lower pressure roller to move closer or further apart. For example, the lifting driver can be a cylinder, thereby driving the upper pressure roller and the lower pressure roller respectively through two lifting drivers, causing the upper pressure roller and the lower pressure roller to move closer together to press and clamp the empty foil area of the electrode sheet.
[0005] Preferably, the mounting base is provided with a slide rail, and a slider is slidably mounted on the slide rail. The upper pressure roller and the lower pressure roller are rotatably mounted on the slider, and the drive end of the lifting driver is connected to the slider. The distance between the upper and lower pressure rollers is adjusted by the lifting driver, allowing them to cross the coating area of the electrode sheet with a large gap. Then, the upper and lower pressure rollers are driven closer together to press and clamp the empty foil area of the electrode sheet.
[0006] Preferably, the displacement driving assembly includes a first driver disposed on the base and a screw connected to the driving end of the first driver, and the pressure roller assembly is threadedly connected to the screw. For example, the first driver may be a stepper motor, which controls the screw to rotate, thereby driving the mounting base to slide on the base, thus precisely adjusting the position of the pressure roller assembly.
[0007] Preferably, the assembly further includes a rotary drive assembly for driving the pressure roller assembly to oscillate. The rotary drive assembly includes a second driver and a transmission rod connected to the driving end of the second driver. The transmission rod is equipped with a transmission component connected to the pressure roller assembly. Therefore, when the electrode's conveying orientation deviates, the second driver drives the transmission rod to rotate, and the transmission component then drives the pressure roller assembly to oscillate, thereby applying a force to the electrode in the direction of the deviation, thus achieving fine adjustment of the electrode's orientation angle.
[0008] Preferably, it further includes a mounting bracket slidably disposed on the base, the mounting base being connected to the mounting bracket, the mounting bracket being provided with a connector threadedly connected to the screw, thereby causing the mounting bracket to move by rotating the screw, thereby causing the pressure roller assembly on the mounting bracket to move along a direction perpendicular to the width of the strip, thereby realizing the pulling and lateral movement of the electrode sheet, and thus completing the position correction of the electrode sheet.
[0009] Preferably, the base is provided with a guide rail, and the mounting frame is slidably mounted on the guide rail via a moving block. Under the action of the displacement driving component, the mounting frame moves back and forth along the guide rail, thereby driving the pressure roller assembly to move laterally and realize the position correction of the electrode sheet.
[0010] Preferably, the system further includes a detection component disposed on the base. The detection component includes a mounting plate disposed on the base and a detector disposed on the mounting plate. The detector is mounted on the mounting plate so that it is located on the electrode conveying path. The detector detects any positional deviation of the electrode, and then the displacement drive component drives the pressure roller assembly to move to complete the position correction.
[0011] Preferably, an oven includes the aforementioned pull-out strip anti-deviation interference device and a strip driving unit. The strip driving unit drives the strip to move along a preset path, and the rolling direction of the upper and lower pressure rollers is consistent with the moving direction of the strip at the contact point with the upper or lower pressure roller. Furthermore, the anti-deviation interference device enables the electrode sheet to be pulled out to correct its position. This improves the positional accuracy of the electrode sheet as it moves within the oven, making the drying position of the electrode sheet controllable.
[0012] Preferably, a coating machine includes the above-mentioned pull-out strip anti-deviation interference device, which can be applied to the electrode conveying process during the coating process of the coating machine and the electrode conveying process during the drying process of the coating machine, thereby improving the accuracy of electrode position.
[0013] Compared with the prior art, the beneficial effects of this application are as follows: This application has a pressure roller assembly slidably arranged on the base, with an upper pressure roller and a lower pressure roller on the pressure roller assembly. The strip passes between the upper pressure roller and the lower pressure roller, and is then clamped by the upper pressure roller and the lower pressure roller. The upper pressure roller and the lower pressure roller make rolling contact with the strip, so that the upper pressure roller and the lower pressure roller cooperate with the strip during the conveying process. A displacement driving component is provided on the base to drive the pressure roller assembly to move. When the strip deviates in position, the displacement driving component drives the pressure roller assembly to move in a direction perpendicular to the width of the strip. The pressure roller assembly then drives the strip to move to correct the deviation, thereby completing the overall position adjustment of the strip, improving the positional accuracy of the strip during the conveying process, and improving production quality.

[0024] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0025] To address the aforementioned technical problems, this embodiment provides a pull-out strip anti-deviation interference device, such as... Figure 1As shown, the system includes a base 10, on which a pressure roller assembly 20 is slidably mounted. The pressure roller assembly 20 has an upper pressure roller 21 and a lower pressure roller 22. The strip passes between the upper pressure roller 21 and the lower pressure roller 22, and is clamped by the upper pressure roller 21 and the lower pressure roller 22. The upper pressure roller 21 and the lower pressure roller 22 make rolling contact with the strip, so that the upper pressure roller 21 and the lower pressure roller 22 roll with the strip during the conveying process. A displacement drive assembly 30 is provided on the base 10 to drive the pressure roller assembly 20 to move. When the strip deviates in position, the displacement drive assembly 30 drives the pressure roller assembly 20 to move in a direction perpendicular to the width of the strip. The pressure roller assembly 20 then moves the strip to correct the deviation, thereby completing the overall position adjustment of the strip, improving the positional accuracy of the strip during the conveying process, and improving production quality.
[0026] Specifically, in this embodiment, the strip material takes the electrode sheet as an example. After the surface of the electrode sheet is coated with foil, the electrode sheet is transported to the drying oven for drying. At this time, the upper pressure roller 21 and the lower pressure roller 22 are pressed and clamped in the empty foil area of the electrode sheet. The displacement driving component 30 drives the pressure roller assembly 20 to move, so that the pressure roller assembly 20 pulls and moves the electrode sheet to complete the position correction of the electrode sheet.
[0027] Furthermore, the pressure roller assembly 20 includes a mounting base 24 slidably disposed on the base 10, with an upper pressure roller 21 and a lower pressure roller 22 slidably disposed on the mounting base 24. The mounting base 24 is provided with a lifting driver 23 for driving the upper pressure roller 21 and the lower pressure roller 22 to move closer or further away from each other. For example, the lifting driver 23 can be a cylinder, thereby driving the upper pressure roller 21 and the lower pressure roller 22 respectively through two lifting drivers 23, so that the upper pressure roller 21 and the lower pressure roller 22 move closer to each other to press and clamp the empty foil area of the electrode sheet.
[0028] In the above scheme, a slide rail 25 is provided on the mounting base 24, and a slider 26 is slidably arranged on the slide rail 25. The upper pressure roller 21 and the lower pressure roller 22 are rotatably arranged on the slider 26, and the driving end of the lifting driver 23 is connected to the slider 26. There are two lifting drivers 23, two slide rails 25, and two sliders 26, so that the height position of the upper pressure roller 21 and the lower pressure roller 22 can be driven independently, thereby adjusting the distance between the upper pressure roller 21 and the lower pressure roller 22. Thus, the upper pressure roller 21 and the lower pressure roller 22 can cross the coating area of the electrode sheet with a large gap, and then drive the upper pressure roller and the lower pressure roller to move closer to each other to press and clamp the empty foil area of the electrode sheet.
[0029] Furthermore, to precisely adjust the position of the pressure roller assembly 20, the displacement drive assembly 30 includes a first driver 31 mounted on the base 10 and a screw 32 connected to the drive end of the first driver 31. The pressure roller assembly 20 is threadedly connected to the screw 32, and the screw 32 is threadedly connected to the mounting base 24. For example, the first driver 31 can be a stepper motor, which controls the rotation of the screw 32, thereby driving the mounting base 24 to slide on the base 10, thus precisely adjusting the position of the pressure roller assembly 20.
[0030] Specifically, such as Figure 4 As shown, a mounting frame 60 is slidably mounted on the base 10. A mounting seat 24 is connected to the mounting frame 60. The mounting frame 60 is equipped with a connector 33, which is threadedly connected to a screw 32. Rotation of the screw 32 causes the connector 33 to move the mounting frame 60, thereby displacing the pressure roller assembly 20 on the mounting frame 60 along a direction perpendicular to the strip width. This achieves the pulling and lateral movement of the electrode sheet, thus correcting its position. The connector 33 can be a lead screw and nut, and is bolted to the mounting frame 60.
[0031] Furthermore, a guide rail 11 is provided on the base 10, and the mounting frame 60 is slidably mounted on the guide rail 11 via the moving block 12. Under the action of the displacement driving component 30, the mounting frame 60 moves back and forth along the guide rail 11, thereby driving the pressure roller assembly 20 to move and realize the position correction of the electrode sheet.
[0032] Furthermore, it also includes a detection component 50 set on the base 10. The detection component 50 is used to detect the positional offset of the strip, and then the detection component 50 detects the offset direction and offset amount of the electrode sheet. Then, the displacement drive component 30 drives the pressure roller component 20 to move to complete the position correction, so as to realize the correction process of the electrode sheet detection and closed-loop control.
[0033] Furthermore, the detection assembly 50 includes a mounting plate 52 disposed on the base 10 and a detector 51 disposed on the mounting plate 52. The detector 51 may be two sets of opposing position sensors. The detector 51 is mounted on the mounting plate 52 so that the detector 51 is located on the electrode conveying path. The detector 51 detects the positional deviation of the electrode, and then drives the pressure roller assembly 20 to move through the displacement drive assembly 30 to complete the position correction.
[0034] Furthermore, such as Figure 2-3As shown, it also includes a rotary drive assembly 40 for driving the pressure roller assembly 20 to swing. The rotary drive assembly 40 includes a second driver 41 disposed on the base 10 and a transmission rod 42 connected to the driving end of the second driver 41. A transmission assembly 43 connected to the pressure roller assembly 20 is disposed on the transmission rod 42. For example, the second driver 41 can be a stepper motor. When the conveying direction of the electrode sheet is offset, the transmission rod 42 is driven to rotate by the second driver 41, and the pressure roller assembly 20 is driven to swing by the transmission assembly 43, thereby applying a force to the electrode sheet in the offset direction to achieve fine adjustment of the electrode sheet orientation angle.
[0035] In the above scheme, the transmission component 43 includes a meshing first gear 431 and a second gear 432. The first gear 431 is mounted on the transmission rod 42, and the second gear 432 is connected to the pressure roller assembly 20 via a connecting seat 27. The first gear 431 and the second gear 432 can be helical gears. Through the meshing of the first gear 431 and the second gear 432, the transmission rod 42 rotates, driving the connecting seat 27 to rotate, which in turn causes the pressure roller assembly 20 to oscillate. In other embodiments, a rotary cylinder can be mounted on the mounting base 24, and the pressure roller assembly 20 can be mounted on the drive end of the rotary cylinder. The rotary cylinder then drives the pressure roller assembly 20 to oscillate and rotate, similarly achieving the function of adjusting the electrode orientation angle.
[0036] This embodiment provides an oven, including the aforementioned pull-out strip anti-deviation interference device and a strip driving unit. The strip driving unit is used to drive the strip to move along a preset path. The rolling direction of the upper pressure roller 21 and the lower pressure roller 22 is consistent with the moving direction of the strip at the contact point with the upper pressure roller 21 or the lower pressure roller 22. Thus, the anti-deviation interference device can pull out the electrode to complete the position correction of the electrode. As a result, when the electrode moves in the oven, the position accuracy of the electrode can be improved, making the drying position of the electrode controllable.
[0037] On the other hand, this embodiment also provides a coating machine, including the above-mentioned pull-out strip anti-deviation interference device, which can be applied to the electrode conveying during the coating process of the coating machine and the electrode conveying during the oven drying process of the coating machine, thereby improving the accuracy of electrode position.
[0038] In summary, in one or more embodiments of this application, a pressure roller assembly is slidably disposed on a base. The pressure roller assembly is provided with an upper pressure roller and a lower pressure roller. The strip passes between the upper and lower pressure rollers and is clamped by the upper and lower pressure rollers. The upper and lower pressure rollers make rolling contact with the strip, so that the upper and lower pressure rollers roll in cooperation with the strip during the conveying process. A displacement driving assembly is provided on the base to drive the pressure roller assembly to move. When the strip deviates in position, the displacement driving assembly drives the pressure roller assembly to move in a direction perpendicular to the width of the strip. The pressure roller assembly then drives the strip to move to correct the deviation, thereby completing the overall position adjustment of the strip, improving the positional accuracy of the strip during the conveying process, and improving production quality.
[0039] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
