Description

Technical Field

[0001] This utility model belongs to the technical field of diaphragm feeding devices, specifically a diaphragm feeding device in the process of laminating flexible circuit boards. Background Technology

[0002] In the lamination process of flexible printed circuit boards (such as FPC flexible circuit boards), the diaphragm feeding device plays a crucial role. The diaphragm feeding device ensures that the diaphragm is smoothly and accurately delivered to the lamination area, thereby improving production efficiency and product quality. Diaphragm feeding devices are widely used in the lamination production of flexible printed circuit boards, especially in production scenarios requiring high precision and efficiency. They can also be used in conjunction with other automated equipment (such as automatic feeders and automatic inspection machines) to form a complete automated production line. This device has significant application value in the lamination production of flexible printed circuit boards.

[0003] However, existing diaphragm feeding devices cannot remove dust adhering to the diaphragm surface during feeding, which affects the pressing quality of the diaphragm during pressing and results in poor performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a diaphragm feeding device in the lamination process of flexible circuit boards, which effectively solves the problem that the existing diaphragm feeding device cannot clean the dust on the surface of the diaphragm during feeding, which affects the lamination quality of the diaphragm and results in poor performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diaphragm feeding device in the lamination process of a flexible circuit board, comprising a support platform, with support legs fixedly installed at the four corners of the bottom of the support platform, an installation frame fixedly installed at one end of the top of the support platform, two drive rollers installed inside the installation frame, an installation bracket fixedly installed at the other end of the top of the support platform, a placement rod rotatably installed on the upper part of one side of the installation bracket, two support rods fixedly installed on one side of the top of the support platform, a support plate fixedly installed between the tops of the two support rods, a cylinder fixedly installed on one side of the support plate, a transmission component provided at the transmission end of the cylinder, two suction heads provided in the middle of the upper part of the support platform, the transmission component being connected to the two suction heads in a transmission manner, and when the cylinder operates, it outputs power to the two suction heads, causing the two suction heads to move closer to the diaphragm.

[0006] Preferably, the transmission assembly includes a connecting plate, which is fixedly installed on the transmission end of the cylinder. Four connecting rods are fixedly installed in a ring at equal intervals on the side of the connecting plate near the cylinder. A connecting plate is fixedly installed between one end of each of the four connecting rods. A movable strip is fixedly installed at each of the four corners on one side of the connecting plate. A transmission plate is fixedly installed at one end of each movable strip. A transmission groove is opened on the surface of each of the four transmission grooves. A transmission pin is movably inserted into the interior of each of the four transmission grooves. The four transmission pins are fixedly connected to both sides of each of the two vacuum heads. A second sliding sleeve is fixedly installed at one end of each of the two vacuum heads. A second sliding rod is movably inserted between the interiors of the two second sliding sleeves. The bottom of the second sliding rod is fixedly connected to the support platform.

[0007] Preferably, the side of the movable strip away from the vacuum head is fixedly installed with a first sliding sleeve by a fixing block, and a first sliding rod is movably inserted into the interior of each of the four first sliding sleeves. A fixing strip is fixedly installed between one end of each of the two first sliding rods on the same side, and the bottom of each of the two fixing strips is fixedly connected to the top of the support platform.

[0008] Preferably, a hose is fixedly installed on the side of each of the two vacuum heads that is far from each other, and a vacuum cleaner is fixedly installed between the ends of the two hoses that are far from the vacuum heads. The bottom of the vacuum cleaner is fixedly connected to the support platform through two pad legs.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the film roll on the placement rod and places one end of the film roll between the two drive rollers. Then, the two drive rollers are started to rotate to transport the film. At the same time as transporting, the operator starts the cylinder to push the connecting plate to move. When the connecting plate moves, it drives the connecting plate to move through the four connecting rods. When the connecting plate moves, it drives the four transmission plates to move through the four moving strips. When the moving strips move, they all drive the first sliding sleeve to slide along the surface of the first sliding rod through the fixed block, which increases the stability of the four moving strips when they move.

[0010] When the four transmission plates move, they drive the two suction heads to move towards each other through the cooperation of the four transmission grooves and four transmission pins. When the suction heads move, they drive the second sliding sleeve to slide along the surface of the second sliding rod, which increases the stability of the two suction heads when they move, so that the two suction heads get closer to the diaphragm. Then the operator starts the vacuum cleaner. When the vacuum cleaner is running, it sucks away the dust on both sides of the diaphragm through the two hoses and the two suction heads. This allows the diaphragm feeding device to effectively clean the dust on the surface of the diaphragm during feeding, so that the dust will not affect the pressing quality of the diaphragm during pressing.

A cylinder 7 is fixedly installed on one side of the support plate 6. A transmission component is provided at the transmission end of the cylinder 7. Two suction heads 15 are provided in the middle of the upper part of the support platform 1. The transmission component is connected to the two suction heads 15. When the cylinder 7 is running, it outputs power to the two suction heads 15, causing the two suction heads 15 to move closer to the diaphragm.

[0019] In use, the operator places the film roll on the placement rod 4 and places one end of the film roll between the two drive rollers 23. Then, the two drive rollers 23 are started to rotate to transport the film. At the same time, the operator starts the cylinder 7 to drive the transmission component to operate. When the transmission component operates, it drives the two dust suction heads 15 to approach the film. At the same time, the transmission component sucks away the dust on both sides of the film through the two dust suction heads 15. This allows the film feeding device to effectively clean the dust on the surface of the film during feeding, so as to avoid the dust affecting the pressing quality of the film during pressing.

[0021] During the conveying process, the operator activates cylinder 7 to move connecting plate 8. As connecting plate 8 moves, it drives connecting plate 10 to move via four connecting rods 9. As connecting plate 10 moves, it drives four transmission plates 12 to move via four moving strips 11. When moving strips 11 move, they all drive first sliding sleeves 17 to slide along the surface of first sliding rods 18 via fixed blocks 16, increasing the stability of the four moving strips 11 during movement.
