Description

[0002] At present, new energy batteries are widely concerned, especially lithium-ion batteries, and are gradually being widely used in fields such as electric bicycles and electric vehicles. The production and processing of lithium batteries widely involves the processing of strips, which are very easy to deviate when transported over long distances. In order to avoid the strip force deflection and uneven force during the conveying of the strip, resulting in unilateral wavy strips, which will affect product quality, the strip needs to be corrected in time.

[0003] In the prior art, such as CN209973800U, a utility model patent for a coating machine correction device, the correction device uses a driving mechanism to drive the support seat to move left and right to correct the deviated strip. It lacks automatic centering of the support seat after correction, and it is difficult to ensure the accuracy after multiple corrections. In addition, the lack of a detection mechanism makes it impossible to monitor the edge position of the strip conveyed by the coating machine in real time, resulting in poor correction of the strip. Secondly, the correction device cannot be installed as a whole on the coating machine to complete the monitoring and automatic correction of the conveyed strip in production, which reduces the correction efficiency and reliability.

[0022] Preferably, it further comprises a plurality of photoelectric sensors, which are arranged on the indicator strip 25 and are electrically connected to a monitoring system and a control system.

[0023] The working principle and beneficial effects of the above technical solution are: The above-mentioned automatic centering bracket for coating machine correction is mainly composed of a support frame 2, a mounting bracket 3, a roller 5, a guide wheel 6, a driving mechanism 7, an adjusting mechanism 8 and a detecting mechanism 9. When the detecting mechanism 9 detects that the conveying strip on the coating machine is offset, the driving mechanism 7 drives the adjusting mechanism 8 to achieve an angular offset of the roller 5 installed on the mounting bracket 3, thereby completing the automatic deviation correction of the strip. When the strip is detected to be deviated during the production of the coating machine, it is necessary to use the automatic centering bracket for coating machine correction to correct it, and the servo motor 122 set in the driving mechanism 7 starts to run. The forward and reverse rotation of the servo motor 122 can complete the correction of the strip deviation to the left or right, and drive the bevel gear 2 123 fixedly connected to the output shaft of the servo motor 122 to rotate synchronously. At the same time, the bevel gear 121 is meshed with the bevel gear 2 123 for transmission, so that the first threaded rod 13 fixedly connected to the bevel gear 121 can rotate, and at the same time, the bottom of the two driving sliders 14 threadedly connected to the second threaded rod 31 with opposite rotation directions can realize smooth movement to the left or right along the precision slide rail 10, thereby ensuring the stability of the driving adjustment mechanism 8, thereby accurately driving the adjustment rod 15 fixedly connected to the driving slider 14 to move synchronously to complete the strip deviation correction.

[0024] At the same time, the adjusting plate 16 in the adjusting mechanism 8 is slidably connected with the second slide groove 21 through the adjusting rod 15, so that the adjusting plate 16 can move left and right, so that the hinge block 18 fixedly connected to the adjusting plate 16 drives the connecting plate 20 connected by the hinge rod 22 to swing left and right along the rotating shaft 19, and at the same time, the rotating shaft 19 connected to the support frame 2 drives the fixedly connected mounting bracket 3 to swing left and right synchronously, and the guide wheel 6 installed on the mounting bracket 3 rotates left and right synchronously with the mounting bracket 3, so as to correct the deviation of the strip on the roller 5 during the conveying process, ensuring that the strip always remains in the correct position during the conveying process; secondly, after the guide wheel 6 on the adjusting mechanism 8 cooperates with the roller 5 to complete the deviation correction of the strip conveying, the driving mechanism 7 drives the adjusting plate 16 to return to its initial position, completing the automatic centering of the coating machine after the deviation correction, and also ensuring the parallelism of the two guide wheel discs 6.

[0025] At the same time, through the two sliding brackets 26 set by the detection mechanism 9, when the strip on the roller 5 deviates to one side, it will drive the sliding bracket 26 to slide to one side along the slide rod 24. At this time, the spring 27 is compressed. At the same time, there are several photoelectric sensors on the indicator strip 25 set between the two fixed plates 23. After detecting the deviation of the strip, they will feedback to the monitoring system to ensure that the automatic centering bracket for coating machine correction can timely identify the deviation of the strip, so that the control system controls the driving mechanism 7 to cooperate with the adjustment mechanism 8 to complete the strip correction.

First, the driving motor 30 arranged on the top of the box body 29 starts to run, so that the second threaded rod 31 fixedly connected to the output shaft of the driving motor 30 with the opposite rotation direction can realize positive and negative rotation. When the surface of the coated strip is cleaned, the fixing frame 34 threadedly connected to the second threaded rod 31 moves inward along the guide column 32, so that the mounting frame 35 connected to the fixing frame 34 through the buffer assembly also moves inward synchronously, and at the same time, the cleaning roller 36 connected to the mounting frame 35 is rotated to contact the upper and lower surfaces of the coated strip, wherein the connecting rod 39 in the buffer mechanism is slidably connected in the fixing sleeve 37 through the spring 38, and the fixing frame 34 and the mounting frame 35 are connected by a number of dry punching components, which provide a buffer for the cleaning roller 36 of the cleaning component 33 when it approaches the strip during the cleaning process, ensuring that the cleaning roller 36 can be sufficiently close to the upper and lower surfaces of the strip, thereby ensuring the effective cleaning of the strip surface. When the cleaning roller 36 is cleaned, the cleaning roller 36 can be cleaned. After the surface of the coated strip is cleaned, the second threaded rod 31 is driven by the driving motor 30 to rotate and drive the two groups of cleaning components 33 to gradually move away to complete the cleaning. At the same time, the auxiliary cleaning mechanism 28 can adapt to the surface cleaning of coated strips of different specifications; at the same time, the liquid storage tank 40 arranged on the outer wall of the box body 29 is in operation.
