Description

Technical Field

[0001] This disclosure relates to the field of automatic battery faceplate technology, and in particular to a faceplate roll unwinding device and an automatic battery faceplate application device. Background Technology

[0002] In battery production, an insulating pad is typically applied to the surface of the electrode plates. Early methods involved manual application, but this was inefficient. Subsequently, an automated battery pad application device, as disclosed in Chinese Patent Document CN 202339956U, was developed. This device first unwinds the pad roll using a pad unwinding device, then pulls the pad to a position directly above the battery using a pad pulling device. The pad is then accurately adhered to the battery electrode plate surface by a pad application device, and finally, a flattening device smooths the pad, thus automating the battery pad application process.

[0003] However, in practical applications, since the unwinding device for the face pad roll is not equipped with a dedicated component for face pad detection, it is difficult for operators to replace the face pad roll in time after a single roll is unwound. In severe cases, this can even lead to production line shutdown, thereby affecting the production efficiency of automatic face pad application for batteries.

[0004] Therefore, some scholars have attempted to apply the photographic detection technology of the battery pad detection device disclosed in Chinese patent CN214845821U to the unwinding device of the pad roll. This involves mounting the camera and light source on one side of the unwinding frame using a mounting bracket to fix them in place. However, if the mounting method described in the aforementioned document is used, when a single roll enters the tail stage, the pad roll lacks effective support in certain areas during transport, causing it to sway during unwinding. This swaying interferes with the camera's ability to achieve stable imaging, resulting in a significant blind spot. Furthermore, traditional detection components require the camera and light source to work together, leading to structural complexity. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a simple structure, which ensures the stability of the unwinding of the face pad roll while reducing the detection blind zone, as well as an automatic battery face pad application device.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A face pad roll unwinding device includes an unwinding frame, a rotating disk, a first unwinding roller, and a second unwinding roller. The rotating disk is located on the top of the unwinding frame and is used to hold the face pad roll. The first unwinding roller and the second unwinding roller are spaced apart on the unwinding frame and located below the discharge port of the rotating disk.

[0008] The padding roll unwinding device further includes a mounting frame and a sensor. The mounting frame extends out from the unwinding frame between the first unwinding roller and the second unwinding roller. The end of the mounting frame away from the unwinding frame forms a conveying channel for the padding roll to pass through. A detection port is formed in the conveying channel. The sensor is located adjacent to the detection port and connected to the mounting frame. The sensing part of the sensor faces the detection port.

[0009] In one embodiment, the mounting frame includes a fixing plate and a cover plate. The mounting portion of the fixing plate is detachably connected to the unwinding frame. The protruding platform of the fixing plate forms a through groove. The through groove has an opening and a detection port. The cover plate covers the opening and is detachably connected to the fixing plate. The cover plate is used to form the conveying channel together with the through groove.

[0010] In one embodiment, the mounting portion of the fixing plate is threadedly connected to the unwinding frame, and / or,

[0011] The fixing plate is located on one side of the unwinding frame.

[0012] In one embodiment, the through groove is formed on the side of the protruding platform of the fixing plate facing the surface pad; and / or,

[0013] The detection port is positioned opposite to the opening.

[0014] In one embodiment, the cover plate and the protrusion of the fixing plate are threaded together.

[0015] In one embodiment, the mounting bracket further includes a support member disposed adjacent to the detection port, with a first end of the support member detachably connected to the fixing plate, a second end of the support member connected to the sensor, and the sensor located above the detection port.

[0016] In one embodiment, the extending direction of the mounting bracket is perpendicular to the extending direction of the support member.

[0017] In one embodiment, the unwinding device for the face pad roll further includes a third unwinding roller disposed between the mounting frame and the second unwinding roller.

[0018] In one embodiment, the third unwinding roller is disposed near the bottom of the unwinding frame, and the third unwinding roller forms an arc-shaped conveying trajectory with the first unwinding roller and the second unwinding roller.

[0019] An automatic battery pad application device includes the pad roll unwinding device described in any of the above embodiments.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] Because the mounting frame extends from the unwinding frame located between the first and second unwinding rollers, the end of the mounting frame away from the unwinding frame forms a conveying channel for the padding roll to pass through. This conveying channel effectively supports the padding roll, preventing it from swaying when entering the tail stage and ensuring the stability of the padding roll unwinding. Furthermore, because a detection port is formed within the conveying channel, and the sensor is located adjacent to the detection port and connected to the mounting frame, with the sensor's sensing part facing the detection port, the sensor can effectively identify the presence of padding roll within the conveying channel. This allows for a more comprehensive detection of the padding roll in the tail stage. Thus, the structure is simple, the stability of the padding roll unwinding is guaranteed, and the detection blind spot is effectively reduced. Attached Figure Description

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0032] Please see Figures 1 to 3 An embodiment of a face pad roll unwinding device 10 includes an unwinding frame 100, a rotating disk 200, a first unwinding roller 300, and a second unwinding roller 400. The rotating disk 200 is disposed on the top of the unwinding frame 100, allowing the rotating disk 200 to be rotatably disposed on the top of the unwinding frame 100. The rotating disk 200 is used to hold the face pad roll 800. The first unwinding roller 300 and the second unwinding roller 400 are spaced apart on the unwinding frame 100 and located below the discharge port of the rotating disk 200. When the face pad roll 800 is suspended on the rotating disk 200, and a portion of the face pad roll 800 is suspended between the first unwinding roller 300 and the second unwinding roller 400, the first unwinding roller 300 or the second unwinding roller 400 is rotated to drive the face pad suspended between the first unwinding roller 300 and the second unwinding roller 400 to move forward, thereby completing the unwinding operation of the face pad roll 800.

[0033] It is understood that, since the padding roll unwinding device 10 also includes a mounting frame 500 and a sensor 600, the mounting frame 500 extends out onto the unwinding frame 100 located between the first unwinding roller 300 and the second unwinding roller 400. One end of the mounting frame 500 away from the unwinding frame 100 forms a conveying channel 513, which is used for the padding roll 800 to pass through. This allows the added conveying channel 513 to effectively support the padding roll 800, effectively preventing the padding roll 800 from swaying when entering the tail stage, and also ensuring... To ensure the stability of the unwinding of the face pad roll 800, a detection port 5122 is formed in the conveying channel 513. The sensor 600 is located adjacent to the detection port 5122 and connected to the mounting frame 500. The sensing part of the sensor 600 is positioned facing the detection port 5122, so that the sensing part of the sensor 600 can effectively identify whether there is face pad in the conveying channel 513, thereby achieving a more comprehensive detection of the face pad roll 800 in the tail stage. In this way, not only is the structure simple, but the stability of the unwinding of the face pad roll 800 is also guaranteed, and the detection blind spot is effectively reduced.

[0034] like Figure 3 and Figure 4 As shown, in one embodiment, the mounting frame 500 includes a fixing plate 510 and a cover plate 520. The mounting portion 511 of the fixing plate 510 is detachably connected to the unwinding frame 100, facilitating quick replacement of the fixing plate 510 by the operator. The protruding platform 512 of the fixing plate 510 forms a through groove 5121, which has an opening and a detection port 5122. The cover plate 520 covers the opening and is detachably connected to the fixing plate 510. The cover plate 520, together with the through groove 5121, forms the conveying channel 513, thereby enabling the cover plate 520 and the fixing plate 510 to be detachably connected while ensuring that the cover plate 520 and the fixing plate 510 are connected to form the conveying channel 513 so that the face pad roll 800 can pass through.

[0035] In one embodiment, the through slot 5121

[0036] In one embodiment, the mounting portion 511 of the fixing plate 510 is threadedly connected to the unwinding frame 100 to achieve a detachable arrangement between the fixing plate 510 and the unwinding frame 100.

[0037] In one embodiment, the fixing plate 510 is located on one side of the unwinding frame 100 to ensure that the fixing plate 510 can form an extension platform 512 on the unwinding frame 100, thereby ensuring that the conveying channel 513 formed by the extension platform 512 can effectively support the padding roll 800 and effectively prevent the padding roll 800 from swinging when it enters the tail stage.

[0038] In one embodiment, the fixing plate 510 includes a mounting portion 511 and a protruding platform 512 connected together, such that the mounting portion 511 is threadedly connected to the unwinding frame 100.

[0039] In one embodiment, the through groove 5121 is formed on the side of the protruding platform 512 of the fixing plate 510 facing the mat; in particular, in conjunction with the use of the cover plate 520, it is ensured that the formed conveying channel 513 can effectively support the mat roll 800.

[0040] In one embodiment, the detection port 5122 is disposed opposite to the opening.

[0041] In one embodiment, the cover plate 520 and the protrusion 512 of the fixing plate 510 are threadedly connected to achieve a detachable arrangement of the cover plate 520 and the fixing plate 510.

[0042] like Figure 3 and Figure 4 As shown, in one embodiment, the mounting bracket 500 further includes a support member 530, which is disposed adjacent to the detection port 5122. The first end of the support member 530 is detachably connected to the fixing plate 510, thereby enabling the support member 530 and the fixing plate 510 to be detachably disposed, facilitating the operator to install and remove the sensor 600 disposed on the support member 530. The second end of the support member 530 is connected to the sensor 600, thereby enabling the support member 530 and the sensor 600 to be connected. Since the sensor 600 is located above the detection port 5122, it is ensured that the sensing part of the sensor 600 can be oriented towards the detection port 5122, ensuring that the sensor 600 can effectively identify whether there is a pad in the conveying channel 513, thereby ensuring the normal operation of the detection.

[0043] In one embodiment, the extending direction of the mounting bracket 500 is perpendicular to the extending direction of the support member 530, so as to ensure that the support member 530 can be vertically mounted on the mounting bracket 500, thereby ensuring that the sensor 600 can be vertically mounted above the detection port 5122, thus ensuring that the sensor 600 can complete the detection quickly and also ensuring the accuracy of the sensor 600 detection.

[0044] In one embodiment, the sensor 600 is located in the middle of the support 530 to ensure that the support 530 can provide more stable support for the sensor 600.

[0045] like Figure 1 and Figure 2As shown, in one embodiment, the padding roll unwinding device 10 further includes a third unwinding roller 700, which is disposed between the mounting frame 500 and the second unwinding roller 400. The added third unwinding roller 700 can better alleviate the tension of the padding roll 800 between the first unwinding roller 300 and the second unwinding roller 400, thereby ensuring the stability of the unwinding of the padding roll 800.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment, the third unwinding roller 700 is disposed near the bottom of the unwinding frame 100, and the third unwinding roller 700 forms an arc-shaped conveying trajectory with the first unwinding roller 300 and the second unwinding roller 400, so as to ensure that the added third unwinding roller 700 can better relieve the tension of the first unwinding roller 300 and the second unwinding roller 400, and better ensure the stability of the unwinding of the padding roll 800.

[0047] Furthermore, in one embodiment, the mounting bracket 500 is located between the first unwinding roller 300 and the third unwinding roller 700, and the mounting bracket 500 is positioned adjacent to the first unwinding roller 300 to better ensure the stability of the unwinding of the face sheet roll 800. Additionally, the mounting bracket 500's proximity to the first unwinding roller 300 ensures that the sensor 600 can quickly detect the signal that the face sheet roll 800 has finished unwinding, facilitating timely roll changing operations by the operator.

[0048] In one embodiment, sensor 600 can be an infrared sensor 600. Of course, sensor 600 can also be other sensors 600 that can achieve detection using existing technology. It is worth mentioning that, since the sensing and detection principle of sensor 600 belongs to the prior art and is not within the scope of protection of this disclosure, this disclosure only protects the connection relationship between sensor 600 and fixing plate 510 and support member 530.

[0049] It should be noted that since the mounting part 511 of the fixing plate 510 is threadedly connected to the unwinding frame 100, the cover plate 520 is threadedly connected to the protruding platform 512 of the fixing plate 510, and the specific structure of the rotating disk 200 and the rotation structure of the rotating disk 200 and the unwinding frame 100 are all prior art, they will not be described in detail in this disclosure.

[0050] This disclosure also provides an automatic battery pad application device, including the pad roll unwinding device 10 described in any of the above embodiments.

[0051] Compared with the prior art, this disclosure has at least the following advantages:

[0052] Since the mounting frame 500 extends from the unwinding frame 100 located between the first unwinding roller 300 and the second unwinding roller 400, the end of the mounting frame 500 away from the unwinding frame 100 forms a conveying channel 513. This conveying channel 513 allows the padding roll 800 to pass through, effectively supporting the padding roll 800 and preventing it from swaying when entering the tail stage. It also ensures the stability of the unwinding of the padding roll 800. A detection port 5122 is formed in the conveying channel 513. The sensor 600 is disposed adjacent to the detection port 5122 and connected to the mounting frame 500. The sensing part of the sensor 600 is disposed facing the detection port 5122, so that the sensing part of the sensor 600 can effectively identify whether there is a pad in the conveying channel 513, thereby realizing a more comprehensive detection of the pad roll 800 in the tail stage. In this way, not only is the structure simple, but the stability of the unwinding of the pad roll 800 is also guaranteed, and the detection blind spot is effectively reduced.

[0053] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
