Description

Technical Field

[0001] This utility model relates to the field of FPC production auxiliary equipment technology, and in particular to a continuous material transfer tooling for FPC production based on negative pressure gripping. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. Due to the high wiring density of FPCs, high-standard quality control is required during their production. To improve product quality, FPC boards undergo a film coating process during manufacturing, and visual inspection is performed after production to ensure the yield and overall quality of FPCs entering the market, reducing the presence of defective products.

[0003] For example, patent document CN119000725B discloses an FPC board inspection device and method equipped with a visual inspection device. It includes a conveying mechanism with a side positioning structure for positioning the FPC board. A lifting assembly is located above the conveying mechanism, and a photographing mechanism for inspecting the appearance of the FPC board is mounted on the lifting assembly. Below the photographing mechanism, two retractable positioning mechanisms are located on the conveying mechanism for positioning the front and rear ends of the FPC board, automatically fine-tuning its position to center it at the shooting position. Simultaneously, while the front and rear positioning mechanisms are positioning, the photographing device descends to the upper surface of the FPC board for clearer imaging. By visually comparing multiple sets of captured images with qualified images, the pass / fail status of the FPC board can be quickly determined, resulting in high inspection efficiency and reduced labor costs. Furthermore, existing lamination processing equipment is also typically designed with similar conveying mechanisms for transporting FPC boards. However, currently, when transferring FPC circuit boards to be processed or inspected between processing equipment corresponding to different processing steps in the production process, it is usually done manually by operators. This method is inefficient and of poor quality, and is highly susceptible to damage to FPC circuit boards due to human error and operator fatigue. In particular, manual transfer and placement operations often cannot accurately and evenly place FPC circuit boards onto the conveyor belt or continuously supply FPC circuit boards to the transfer structure of the processing equipment. Calibration and position adjustment structures need to be added to the conveyor belt of the processing equipment to ensure the accuracy of the FPC circuit board positions, increasing the complexity and investment cost of the equipment, and leading to increased maintenance costs. Furthermore, operators are limited by physical strength and often require intermittent rest time, hindering continuous processing of FPC circuit boards and reducing continuous production efficiency. In addition, while existing robotic arms can achieve multi-functional automated grasping of samples, they are costly and structurally complex, making them inconvenient for multi-station deployment. Therefore, there is a need to design a low-cost and efficient continuous material transfer fixture for FPC circuit boards. Utility Model Content

[0004] The purpose of this invention is to provide a continuous material transfer fixture for FPC production based on negative pressure gripping, which can reduce manufacturing costs and replace manual labor for high-quality and efficient continuous material transfer, thereby improving the automation level and supply quality of FPC circuit board transfer and placement, and reducing labor costs and defect rates. This fixture addresses the problems of existing manual placement, such as poor placement accuracy, susceptibility to errors due to human condition leading to decreased product yield, low manual operation speed limiting continuous material transfer and placement, and high cost and maintenance difficulty of robotic arms, which prevents multi-point deployment and fails to meet the needs of cost reduction and efficiency improvement.

The first main pipe is connected to two parallel second branch pipes to form a diversion channel. The upper axial end of the first main pipe is connected to the negative pressure suction unit.

[0008] According to a preferred embodiment, the deflection separation assembly is further provided on the pipe body docking edge of the two second branch pipes. The deflection plate of the deflection separation assembly is mounted on the pipe body docking edge of the two second branch pipes via a rotating shaft. A magnetic block capable of magnetically limiting the deflection plate is also embedded on the pipe end face of the first main pipe. A lifting rod capable of pushing the deflection plate to rotate and being aligned is also vertically inserted on the main housing. A limiting spring capable of limiting its initial working position is sleeved on the axial lower end of the lifting rod extending to the outside of the main housing.

[0009] According to a preferred embodiment, the upper axial end of the lifting rod is provided with a push head, and the lower axial end of the lifting rod is provided with a limiting block that limits the sleeve position of the limiting spring; a sealing gasket ring capable of filling the insertion gap is also sleeved on the rod body of the lifting rod; and a pressure relief channel is also provided in the rod body of the lifting rod.

The continuous feeding component of this application can simultaneously realize different operations at two workstations, namely sheet material gripping and sheet material placement, which greatly improves the overall processing efficiency during continuous sheet material transfer and placement. Moreover, a single stroke of motion can realize a single operation process at both workstations. Compared with the current situation where existing robotic arms and manual operations require two back-and-forth strokes to complete one transfer and one placement operation, the continuous feeding component of this application shortens the total time to complete one transfer and one placement, increases the duration of a single operation cycle when supplying sheet materials, and improves the continuous supply speed and efficiency during FPC production.
