Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a rolling device and an electrode processing device. Background Technology

[0002] In battery production, the rolling of sheet metal is an essential step. Rolling refers to the rotational pressing of sheet metal using a rigid cylindrical structure. During the rolling process, the condition of the rollers plays a decisive role in the rolling effect. For example, if the horizontality of the two ends of the roller is inconsistent, the roller will vibrate, resulting in deformed and wrinkled sheet metal. However, due to the weight of the rollers, the vibrations are usually subtle and imperceptible to the naked eye. The resulting sheet metal problems may also be intermittent. Therefore, when sheet metal problems occur during actual production, it is difficult to directly determine whether roller vibration is the cause. In other words, existing rolling devices suffer from the problem of difficulty in detecting and promptly addressing roller vibration. Utility Model Content

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] See Figure 1 As shown, an embodiment of the first aspect of this application discloses a roller pressing device, including a roller pressing assembly, a detection assembly, and an alarm 400.

[0034] Specifically, the rolling assembly includes a first pressure roller 110, which is used to roll and press sheet material; the monitoring assembly includes a first contour sensor 210, which is provided at both ends of the first pressure roller 110 and is used to monitor the contour position of the first pressure roller 110; and an alarm 400 is electrically connected to the first sensor and is used to issue an alarm prompt.

[0035] The sheet material can be an electrode sheet or other single strip material, or it can be a laminated or composite structure of multiple strip materials. For example, in one possible embodiment, the sheet material is specifically a laminated structure of a first adhesive strip, an electrode sheet, and a second adhesive strip arranged sequentially.

[0036] In the roller pressing device provided in this application embodiment, first contour sensors 210 are set at both ends of the first pressure roller 110. The first contour sensors 210 detect the contour position at both ends of the first pressure roller 110. When the first pressure roller 110 vibrates, the first contour sensors 210 can accurately monitor the vibration of the first pressure roller 110. The alarm 400 can trigger an alarm prompt based on the signal from the first sensor. In this way, the vibration of the first pressure roller 110 can be accurately monitored, reducing the difficulty of detecting the vibration of the first pressure roller 110 and facilitating technicians to deal with the vibration problem of the first pressure roller 110 in a timely manner.

[0037] In one embodiment, see Figure 2When the first contour sensor 210 detects a change in the contour position of the first pressure roller 110, the first contour sensor 210 generates a signal, which controls the transistor to turn on, thereby causing the alarm 400 to sound an alarm.

[0038] In one embodiment, the roller pressing device includes a controller, the input of which is electrically connected to a first contour sensor 210, and the output of which is electrically connected to an alarm 400. The controller is used to determine the vibration of the first pressing roller 110 based on the contour position obtained by the first contour sensor 210, and to control the alarm 400 based on the vibration.

[0039] In one embodiment, see Figure 1 The rolling assembly includes a second pressure roller 120, which is disposed on one side of the first pressure roller 110. The monitoring assembly includes a second contour sensor 220, which is disposed at both ends of the second pressure roller 120. The second contour sensor 220 is electrically connected to an alarm 400 and is used to detect the contour position of the second pressure roller 120. By setting the second contour sensor 220 at both ends of the second pressure roller 120 to detect the contour position of the second pressure roller 120, the alarm 400 will sound when the second pressure roller 120 vibrates, thus alerting technicians to the vibration of the second pressure roller 120. In this way, technicians can visually detect the vibration of the second pressure roller 120 and be alerted to handle it in a timely manner.

[0040] In one possible application scenario, the rolling assembly is used to roll the laminated structure of electrode 1, first material strip 2, and second material strip 2. Specifically, electrode 1 is disposed between first material strip 1 and second material strip 2, and a rolling space is defined between first pressure roller 110 and second pressure roller 120. Electrode 1, first material strip 1, and second material strip 2 are conveyed together into the rolling space for rolling.

[0041] It is understandable that the first material strip 1 and the second material strip 2 can be configured as tape, diaphragm, or other structures as needed, and no limitation is made here.

[0042] In one embodiment, the roller pressing assembly includes an adjustment mechanism connected to a first pressure roller 110. The adjustment mechanism drives the first pressure roller 110 to move radially, thereby adjusting the relative position of the first pressure roller 110 and the second pressure roller 120. Thus, when it is necessary to adjust the parallelism of the two ends of the first pressure roller 110, the adjustment mechanism can drive the first pressure roller 110 to move back to a position parallel to the second pressure roller 120.

[0043] It is worth understanding that in the above embodiments, the position of the second pressure roller 120 is relatively fixed and is not easy to change during the rolling process. Therefore, it is usually not necessary to adjust the position of the second pressure roller 120.

[0044] In one embodiment, see Figure 1 The adjustment mechanism includes a first support structure 310 and a second support structure 320. The first support structure 310 is connected to one end of the first pressure roller 110, and the second support structure 320 is connected to the other end of the first pressure roller 110. The first support structure 310 and the second support structure 320 are respectively used to drive the first pressure roller 110 to move up and down. That is, the first support structure 310 and the second support structure 320 can independently drive the ends connected to them to move up and down. The first support structure 310 and the second support structure 320 work together to adjust the parallelism of the first pressure roller 110. Thus, when the first pressure roller 110 deviates from the preset position, the first support structure 310 and the second lifting structure can be controlled to move up and down respectively to drive the first pressure roller 110 back to the preset position, thereby effectively solving the problem of vibration of the first pressure roller 110.

[0045] In one embodiment, a pressure sensor 230 is provided between the first support structure 310 and the first pressure roller 110. The pressure sensor 230 is used to detect the current pressure between the first support structure 310 and the first pressure roller 110. By comparing the current pressure with a preset roller pressure, the deviation direction of the first pressure roller 110 can be determined. For example, if the current pressure is greater than the preset roller pressure, it indicates that the distance between the first pressure roller 110 and the second pressure roller 120 is less than a preset distance. Since the position of the second pressure roller 120 is relatively fixed, it can be determined that the end of the first pressure roller 110 corresponding to the first support structure 310 is offset towards the second pressure roller 120. Therefore, by driving the first support structure 310 to descend, the end of the first pressure roller 110 connected to the first support structure 310 descends, allowing the first pressure roller 110 to move back to the preset position.

[0046] In one embodiment, a pressure sensor 230 is provided between the second support structure 320 and the first pressure roller 110. The pressure sensor 230 is used to detect the current pressure between the second support structure 320 and the first pressure roller 110. By comparing the current pressure with a preset roller pressure, the deviation direction of the first pressure roller 110 can be determined. For example, if the current pressure is greater than the preset roller pressure, it indicates that the distance between the first pressure roller 110 and the second pressure roller 120 is less than a preset distance. Since the position of the second pressure roller 120 is relatively fixed, it can be determined that the end of the first pressure roller 110 corresponding to the second support structure 320 is offset towards the side of the second pressure roller 120. Therefore, by driving the second support structure 320 to descend, the end of the first pressure roller 110 connected to the second support structure 320 descends, allowing the first pressure roller 110 to move back to the preset position.

[0047] In one embodiment, the monitoring component includes a first support 130, an abutment structure 240, and a distance sensor 250. One end of the first pressure roller 110 is rotatably mounted on the first support 130, the abutment structure 240 is mounted on the first support 130, and the distance sensor 250 is connected to the second pressure roller 120. The distance sensor 250 is used to abut against the abutment structure 240 to detect the distance between the first pressure roller 110 and a preset position. When the roller pressing device is running, the first support structure 310 and the second support structure 320 output support force and push the first pressure roller 110 upward, so that the first pressure roller 110 and the second pressure roller 120 cooperate to roll. At this time, the abutment structure 240 abuts against the distance sensor 250. The distance sensor 250 collects the distance of the first pressure roller 110. When the distance difference between the distance of the first pressure roller 110 and the preset distance exceeds the preset threshold, the output of the first support structure 310 and the second support structure 320 is adjusted by combining the distance difference with the pressure collected by the current pressure sensor 230, so as to drive the first pressure roller 110 to adjust to the preset position.

[0048] For example, when the distance difference is greater than a preset threshold, if the pressure collected by the pressure sensor 230 is less than the pressure during normal rolling, it means that the first pressure roller 110 is farther away from the second pressure roller 120 relative to the preset position; if the pressure collected by the pressure sensor 230 is greater than the pressure during normal rolling, it means that the first pressure roller 110 is closer to the second pressure roller 120 relative to the preset position.

[0049] In one embodiment, see Figures 3 to 5The roller pressing assembly includes an adjusting component 260, which includes a first slope block 261 and a second slope block 262. The first slope block 261 is mounted on the first bracket 130, and the second slope block 262 is connected to one end of the second pressure roller 120. When the first pressure roller 110 and the second pressure roller 120 are engaged in roller pressing, the first slope block and the second slope block 262 abut against each other to provide a fixing function and prevent slight fluctuations from causing displacement of the first pressure roller 110. The mating surfaces of the first slope block 261 and the second slope block 262 are wedge-shaped inclined surfaces.

[0050] Furthermore, in the above embodiments, by driving the first slope block 261 and the second slope block 262 to move relative to each other, a small adjustment of the distance between the first pressure roller 110 and the second pressure roller 120 is achieved, which helps to improve the accuracy of the distance adjustment.

[0051] In this embodiment, please continue to refer to Figures 3 to 5 As shown, the adjustment component 260 includes a rotation drive 263, which drives the second slope block 262 to move via a screw. The second slope block 262 abuts against the first slope block 261 via a wedge-shaped inclined surface, thereby changing the distance between the first pressure roller 110 and the second pressure roller 120.

[0052] In one embodiment, see Figure 6 The roller pressing assembly includes a support frame 141, a tray 142, and a limiting and fixing structure. The tray 142 is detachably mounted on the support frame 141. The first pressure roller 110 is mounted on the tray 142. A limiting hole is provided on one side of the tray 142. The limiting and fixing structure includes a limiting rod 1431, which is used to cooperate with the limiting hole. When replacing the first pressure roller 110, after removing the connecting bolts between the tray 142 and the support frame 141, the tray 142 and the first pressure roller 110 can be pulled out together in the opposite direction of the X direction. Then, another tray 142 mounted on the first pressure roller 110 is pushed in along the X direction and fixed, thereby realizing the replacement of the first pressure roller 110. During the process of pushing the tray 142 in the X direction, the limiting rod 1431 cooperates with the limiting hole to position the tray 142 in the X direction, which helps to ensure the installation accuracy of the first pressure roller 110.
