Description

Technical Field

[0001] The utility model relates to the technical field of circuit board pressurization, in particular to an adjustable pressurization device for producing flexible circuit boards. Background Art

[0002] Flexible circuit board is a circuit board with a relatively soft material. During processing, a clamping device is required to pressurize the flexible circuit board.

[0003] After searching (application number: 202320866705.6), it can be learned that the adjustable pressurizing device for flexible circuit board production includes a frame and a hydraulic lift. A hydraulic lifting rod is provided at the lower end of the hydraulic lift, a unloading mechanism is provided at the side end of the rotating support plate, and a material storage and heat dissipation box is provided on the lower side of the rotating support plate. The interior of the material storage and heat dissipation box is provided with a water cooling mechanism and an air cooling mechanism.

[0004] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: although the pressurizing device has the function of circuit board detachment from the work station and air blowing cooling, the circuit board is flexible and is more easily deformed after hot pressing. It adopts a tipping method and a subsequent side blowing method, which can easily cause irregular deformation of the flexible circuit board. After cooling and forming, there is an influence on the morphology, which affects the quality of the product, so that improvement is urgently needed. Therefore, we propose an adjustable pressurizing device for the production of flexible circuit boards. Utility Model Content
