Description

Technical Field

[0001] This utility model relates to the field of lithium battery coating technology, specifically to an automatic roller adjustment device system. Background Technology

[0002] In recent years, the global transition to green and low-carbon energy has accelerated, with new energy sources, represented by electric vehicles and energy storage, experiencing sustained large-scale growth and significant progress in decarbonizing the power system. However, with the widespread adoption of new energy sources on a large scale, some new technological challenges and systemic problems have gradually emerged, posing new and higher requirements for the development of green and low-carbon energy sources such as power batteries.

[0003] Currently, coating, as a front-end process in lithium battery manufacturing, plays a crucial role in battery quality and reliability. Conventional lithium battery coating machines use an initial setting method to control the blank width of the coating foil, which may cause lateral deviations during the coating process, resulting in poor accuracy in controlling the coating blank width. Utility Model Content

[0004] The purpose of this invention is to provide an automatic adjustment device system for printing rollers that can solve the problem of misalignment of blank spaces.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] An automatic printing roller adjustment system includes a U-shaped base installed between two field wall panels. A drive base plate is mounted on the upper surface of the U-shaped base via a translation mechanism. Side plates are mounted on both sides of the upper surface of the drive base plate, and a printing roller is positioned between the two side plates. A drive mechanism is provided on the outer surface of the field wall panels, and the drive mechanism is in transmission cooperation with the translation mechanism to drive the drive base plate to move horizontally. A color matching photoelectric sensor is installed between the two field wall panels.

[0007] It can be seen that by monitoring the offset of the foil material through the color matching photoelectric sensor, and through the driving mechanism and translation mechanism, the printing roller can perform adaptive and precise displacement compensation when the foil material is offset, thereby controlling the precise over-control of the blank width of the coating area.

[0008] Furthermore, the translation mechanism includes a lead screw rotatably mounted between the inner walls of both sides of the U-shaped seat, and a drive base plate mounted on the outer surface of the lead screw. A limiting groove is formed on the upper surface of the U-shaped seat in the horizontal direction, and a limiting slider is provided inside the limiting groove, with the end of the limiting slider connected to the lower surface of the drive base plate. Driven by the threaded connection of the lead screw, the printing roller can perform adaptive and precise displacement compensation.

[0009] Furthermore, the drive mechanism includes a mounting base installed on the outer surface of the field wall panel. A motor mounting plate is provided on the surface of the mounting base, and a drive motor is mounted on the inner side of the motor mounting plate. The output shaft of the drive motor extends through to the other side of the motor mounting plate and is fitted with a second pulley. The end of a lead screw extends through to the outer side of the field wall panel and is connected to a rotating shaft via a coupling. A first pulley is mounted on the end of the rotating shaft, and a transmission belt is fitted onto the outer surfaces of both the first and second pulleys. The drive motor is electrically connected to the color-matching photoelectric sensor. When the drive motor starts, it rotates the lead screw to complete the command execution action, thereby achieving precise compensation for offset.

[0010] Furthermore, a crossbar is installed between the two on-site wall panels, and a sliding sleeve is slidably mounted on the outer surface of the crossbar, with the color matching photoelectric sensor mounted on the upper surface of the sliding sleeve. Screws are installed at the bottom of the sliding sleeve. The position of the color matching photoelectric sensor can be adjusted to accommodate monitoring foil materials of different widths.

[0011] Furthermore, a fixing plate is installed at the end of the mounting base, and the surface of the fixing plate is provided with a clearance groove. Elongated holes extending vertically are provided at each of the four corners of the motor mounting plate surface, and the motor mounting plate is connected to the fixing plate by bolts. This allows for adjustment of the tension of the drive belt, ensuring precise transmission.

[0012] Furthermore, the drive motor is a servo motor. Servo motors have high precision characteristics, enabling adaptive and precise displacement compensation of the printing roller when the foil material shifts, thereby accurately controlling the width of the blank area in the coating region.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] This invention monitors the offset of the foil material using a color-matching photoelectric sensor, and through the driving mechanism and translation mechanism, enables the printing roller to perform adaptive and precise displacement compensation when the foil material shifts, thereby controlling the precise over-control of the white space width of the coating area.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5 As shown, an automatic printing roller adjustment device system includes a U-shaped base 101 installed between two field wall panels 1. A drive base plate 102 is mounted on the upper surface of the U-shaped base 101 via a translation mechanism 2. Side plates 103 are installed on both sides of the upper surface of the drive base plate 102, and a printing roller 104 is disposed between the two side plates 103. A drive mechanism 3 is disposed on the outer surface of the field wall panel 1, and the drive mechanism 3 is in transmission cooperation with the translation mechanism 2 to drive the drive base plate 102 to move horizontally. A color matching photoelectric sensor 105 is disposed between the two field wall panels 1.

[0019] The offset of the foil is monitored by the color matching photoelectric sensor 105. During the coating production process, once the foil moves at high speed among many rollers and causes lateral offset, the printing roller 104 performs adaptive and precise displacement compensation when the foil is offset by the drive mechanism 3 and the translation mechanism 2, thereby controlling the precise over-control of the white space width of the coating area.

[0020] Preferably, the translation mechanism 2 includes a lead screw 201 rotatably mounted between the inner walls of both sides of the U-shaped seat 101, and a drive base plate 102 mounted on the outer surface of the lead screw 201. A limiting groove 202 is formed on the upper surface of the U-shaped seat 101 in the horizontal direction, and a limiting slider 203 is provided inside the limiting groove 202, and the end of the limiting slider 203 is connected to the lower surface of the drive base plate 102.

[0021] When the lead screw 201 is started to rotate by the drive mechanism 3, the drive base plate 102 is limited by the limiting slider 203 and the limiting groove 202, causing the drive base plate 102 to move horizontally under the action of the threaded connection, thereby driving the printing roller 104 to perform adaptive and precise displacement compensation.

[0022] Preferably, the drive mechanism 3 includes a mounting base 301 mounted on the outer surface of the field wall panel 1. A motor mounting plate 302 is provided on the surface of the mounting base 301. A drive motor 303 is mounted on the inner side of the motor mounting plate 302. The output shaft of the drive motor 303 extends through to the other side of the motor mounting plate 302 and is fitted with a second pulley 307. The end of the lead screw 201 extends through to the outer side of the field wall panel 1 and is connected to a rotating shaft 305 via a coupling 304. A first pulley 306 is mounted on the end of the rotating shaft 305. A transmission belt 308 is fitted onto the outer surfaces of the first pulley 306 and the second pulley 307. The drive motor 303 is electrically connected to the color-changing photoelectric sensor 105.

[0023] The offset information is collected by the color-matching photoelectric sensor 105 and sent to the controller (not shown in the figure). After the controller processes and calculates the data, it sends instructions and parameters to the drive motor 303. The drive motor 303 starts and drives the second pulley 307 to rotate. Through the transmission belt 308, the lead screw 201 can be rotated to complete the instruction execution action, thereby achieving the purpose of accurate offset compensation.

[0024] like Figure 6 As shown, the printing roller 104 can be controlled in a closed loop as well as in an online open loop. The open loop provides basic efficiency, while the closed loop ensures final accuracy. The combination of the two enables the system to respond quickly and complete tasks with high precision.

[0025] Preferably, a crossbar 4 is installed between the two on-site wall panels 1, and a sliding sleeve 401 is slidably installed on the outer surface of the crossbar 4, with a color photoelectric sensor 105 installed on the upper surface of the sliding sleeve 401. A screw 402 is installed at the bottom of the sliding sleeve 401.

[0026] The position of the color matching photoelectric sensor 105 can be adjusted by sliding the sliding sleeve 401 to adapt to the monitoring of foil materials of different widths. Then, tighten the screw 402 to fix the position and angle of the color matching photoelectric sensor 105.

[0027] Preferably, a fixing plate 5 is installed at the end of the mounting base 301, and a clearance groove 501 is provided on the surface of the fixing plate 5. Elongated slots 3021 extending in the vertical direction are provided at the four corners of the surface of the motor mounting plate 302, and the motor mounting plate 302 is connected to the fixing plate 5 by bolts.

[0028] The elongated hole 3021 allows the installation position of the motor mounting plate 302 to be adjusted vertically, thereby adjusting the tension of the transmission belt 308 and ensuring precise transmission.

[0029] Preferably, the drive motor 303 is a servo motor.

[0030] Servo motors achieve micron-level or even higher precision in positioning, speed control, and trajectory tracking. The set linear displacement of the drive base plate 102 driven by the drive motor 303 is 2mm, the control accuracy of the positive / negative blank width is ±0.25mm, and the control accuracy of the AB surface alignment is ±0.5mm. This enables the printing roller 104 to perform adaptive and precise displacement compensation when the foil material shifts, thereby controlling the precise over-control of the blank width of the coating area.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
