Description

Technical Field

[0001] This utility model relates to the technical field of flexible film tension constant system based on counterweight mechanism and motor speed control, and particularly to a flexible film tension constant system based on counterweight mechanism and motor speed control. Background Technology

[0002] In modern electronics manufacturing, flexible films are widely used in various industries such as 3C electronics, semiconductor manufacturing, food processing, and medical applications. However, effectively controlling the tension of flexible films during production and testing has become a critical issue. Film tension not only affects production quality but also directly relates to the reliability and lifespan of circuits.

[0003] In traditional flexible thin-film circuit production and testing processes, precise control of film tension is often difficult due to the inherent physical properties of the thin-film material and limitations of production equipment. This is particularly true during the testing stage, where insufficient tension during film transport on the testing drum can lead to slack or wrinkles, resulting in decreased testing accuracy. Conversely, excessive tension can damage the thin-film circuit, causing unnecessary waste. In the current flexible thin-film processing and testing industry, a tension control system is crucial for ensuring that the film remains flat, wrinkle-free, and free from overstretching during processing and transport.

[0004] Furthermore, with the continuous expansion of applications for flexible thin-film circuits, the requirements for thin-film materials are becoming increasingly stringent. Different thin-film materials possess different physical properties and tension requirements, and traditional tension control methods often struggle to meet these diverse needs. Therefore, designing a system capable of adapting to different thin-film materials and achieving precise tension control has become a critical technical challenge in the production and testing of flexible thin-film circuits.

[0027] Reference Figures 1 to 3 , the specific embodiment proposed in the utility model.

[0028] The utility model provides a kind of flexible film tension constant system based on counterweight mechanism and motor rotating speed control, it include: unwinding mechanism 10, detection wheel mechanism 20, counterweight mechanism 30 and winding mechanism 40;The unwinding mechanism 10 includes unwinding motor 11 and unwinding air inflation shaft 12, for the unwinding of film circuit roll material 60;The detection wheel mechanism 20 includes rotary drum motor 21 and detection rotary drum 22, it is set in one side of unwinding mechanism 10;The counterweight mechanism 30 is respectively set in two sides of the detection wheel mechanism 20, for the keeping constant tension of film on the detection rotary drum 22;The winding mechanism 40 of described, it is set in one side of the detection wheel mechanism 20, including winding motor 41 and winding air inflation shaft 42, for the winding of film circuit roll material 60.The utility model's structure is simple, realizes the tension constant of system by counterweight mechanism 30, reduces system cost, reduces equipment failure rate and maintenance requirement.

[0029] In one of the embodiments, the counterweight mechanism 30 comprises a detection bracket 31, a counterweight guide rod 32 arranged on the detection bracket 31, a sliding block 33 movable along the guide of the counterweight guide rod 32, a counterweight block 34 arranged on the sliding block 33, a counterweight roller shaft 35 connected with the counterweight block 34, a buffer spring 36 arranged on the counterweight guide rod 32 and below the counterweight block 34, an upper tension adjustment sensor 37 and a lower tension adjustment sensor 38 arranged corresponding to the counterweight roller shaft 35, and a sensing sheet 39 corresponding to the upper tension adjustment sensor 37 and the lower tension adjustment sensor 38; the unwinding motor 11, the winding motor 41, and the rotating drum motor 21 are electrically connected with the upper tension adjustment sensor 37 and the lower tension adjustment sensor 38. The upper tension adjustment sensor 37 and the lower tension adjustment sensor 38 and the sensing sheet 39 corresponding thereto monitor and adjust the sliding state of the counterweight mechanism 30 in real time, so as to realize the constant tension of the system. In the detection process, as the outer diameter of the material roll at the unwinding end and the winding end changes, the linear speed of the material at the unwinding end and the winding end also changes. As the work proceeds, the diameter of the material roll at the unwinding end becomes smaller, and the linear speed also becomes smaller. Since the speed of the detection rotating drum 22 remains constant, the counterweight roller shaft 35 close to the unwinding end is slowly pulled upward. When the counterweight roller shaft 35 rises to the sensing sheet 39 and triggers the upper tension adjustment sensor 37, the system controls the unwinding motor 11 to speed up. At this time, the sliding block 33 in the counterweight mechanism 30 close to the unwinding motor 11 side will descend until the sensing sheet 39 triggers the lower tension adjustment sensor 38, and then the unwinding motor 11 returns to normal speed. As the work proceeds, the diameter of the material roll at the winding end becomes larger, and the linear speed at the winding end also increases. Since the speed of the detection rotating drum 22 remains constant, the counterweight roller shaft 35 close to the winding end is slowly pulled upward. When the counterweight roller shaft 35 rises to the sensing sheet 39 and triggers the upper tension adjustment sensor 37, the system controls the winding motor 41 to slow down. At this time, the sliding block 33 in the counterweight mechanism 30 close to the winding motor 41 side will descend until the sensing sheet 39 triggers the lower tension adjustment sensor 38, and then the winding motor 41 returns to normal speed. The above actions are repeated to prevent the sliding parts of the counterweight mechanism 30 from touching the upper connecting plate or the bottom plate, so as to keep the system tension constant.

[0030] In one of the embodiments, a compression roller assembly is arranged on both sides of the detection rotating drum 22 respectively, and the compression roller assembly is used to tightly adhere the film to the detection rotating drum 22.

[0031] In one of the embodiments, the counterweight block 34 is detachably arranged, and different numbers of counterweight blocks 34 are arranged according to the material of the film circuit material roll 60, so as to flexibly adjust the material of the film circuit material roll 60.

[0032] In one of the embodiments, the counterweight blocks 34 of the two counterweight mechanisms 30 are arranged in consistent quantity and weight, the tension of the film circuit roll 60 on both sides of the detection roller 22 is consistent, the tension on both sides is counteracted, and the friction between the detection roller 22 and the film circuit roll 60 drives the film circuit roll 60 to move forward.

[0033] In one of the embodiments, the detection wheel mechanism 20 comprises a detection bracket 31, and the roller motor 21 and the detection roller 22 are arranged on the detection bracket 31.

[0034] In one of the embodiments, a guide roller shaft 50 is arranged between the unwinding mechanism 10 and the detection wheel mechanism 20.
