Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board production, in particular to a gluing device used for flexible circuit board production. Background Art

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties and can meet the design needs of smaller and higher-density installations. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. They can be bent, wound, and folded freely. Flexible circuit boards can greatly reduce the size and weight of electronic products and are suitable for the development of electronic products towards high density, miniaturization, and high reliability.

[0003] In the production process of flexible circuit boards, a gluing device for flexible circuit boards is required. In the prior art, a conveyor belt is usually used to transport the circuit boards during the gluing process. When the conveyor belt is transporting the circuit boards, the position of the circuit boards may be slightly offset due to factors such as speed, tension or mechanical errors. This offset may cause inaccurate alignment between the back glue and the circuit board during the gluing process, thereby affecting the bonding quality and product performance. In addition, since the flexible circuit board itself is relatively soft, it is easy for the circuit board to be unevenly bonded during the bonding process due to loose fixation. Therefore, a gluing device for flexible circuit board production is proposed to solve the above problems. Utility Model Content

[0009] Furthermore, a bearing adapted to the rotating shaft is fixedly installed inside the workbench, the driven gear is fixedly installed on the outside of the rotating shaft and meshed with the transmission gear, the mounting plate is fixedly connected to the end of the rotating shaft away from the workbench, and the four lower mold tools are distributed in a ring shape on the top of the mounting plate.

[0010] Furthermore, the mounting cylinder is fixedly mounted inside the lower die jig, the spring is fixedly connected to the inner bottom wall of the mounting cylinder, and the connecting plate is fixedly connected to an end of the spring away from the mounting cylinder.

[0011] Furthermore, the connecting rod is fixedly connected to the top of the connecting plate and extends to the outside of the mounting tube. A movable opening adapted to the connecting rod is provided inside the mounting tube. The support plate is fixedly connected to one end of the connecting rod away from the connecting plate.
