Description

Technical Field

[0001] The present invention belongs to the technical field of MLCC lamination production, and specifically is a tension synchronization control compensation mechanism for an MLCC lamination machine. Background Art

[0002] Traditional tension control compensation uses a rocker mechanism driven by a servo motor. Because the film material's path is an arc, the rocker drive easily causes the film material to deviate along the arc. After a period of time, the error accumulates, and the front-end unwinding correction cannot correct it. At this time, the alignment mark on the electrode film will be out of the original CCD field of view, making it impossible to detect the alignment mark.

[0003] Traditional tension control compensation adopts a dual-support single-motor direct drive mode. Since there will be gaps at the support rotation points on both sides during the assembly process, a certain gap will be eliminated on the side close to the motor due to the direct drive force of the motor, but the gap on the side away from the motor cannot be eliminated. In this way, a slight torsion will occur during operation, causing tension fluctuations, which will also cause the film material to deviate, making it impossible to detect the alignment mark point.

[0037] When in use, start the two servo motors 132. The operation of the servo motor 132 will drive the screw assembly 11 to rotate through the coupling 14. The screw assembly 11 will drive the pushing assembly 5 to move back and forth in the horizontal direction. Start the cylinder 4. The operation of the cylinder 4 will drive the pushing assembly 5 as a whole to perform horizontal back and forth adjustment movement. The cylinder pushing plate 51 and the roller mounting plate 53 will drive the roller 52 to move inside the linear slide 9. The linear slide 9 will guide the operation of the pushing assembly 5 to ensure its overall stability. At the same time, starting the differential head 62 will adjust the parallelism of the pushing assembly 5 to prevent it from tilting. The encoder mounting seat 81 and the encoder 82 will measure the length of the film material, thereby controlling the running speed of the winding and unwinding. At the same time, the cooperation of the sensor 101 and the sensor guide rail 102 will sense the distance and position signal of the pushing assembly 5 to prevent it from colliding.
