Description

Technical Field

[0001] This application belongs to the field of automated production equipment technology, and specifically relates to the application of automatic ejection mechanisms in the field of flexible circuit boards. Background Technology

[0002] As electronic products demand increasingly higher yield rates and production efficiency, manual operation is no longer sufficient to meet the manufacturing requirements, such as for conventional circuit boards and flexible printed circuit boards (FPCs). In existing production lines, when placing electrical components on the FPC, the lack of a fixed base allows external factors to cause the FPC's position to shift. Furthermore, after the components are packaged, the entire FPC is in close contact with the mold, hindering separation. These factors combined result in low loading and unloading efficiency and a high risk of carriers falling and being damaged.

[0003] In the publication document CN118905601A, an automatic feeding and assembly equipment is described, where a carrier lifting assembly includes a lifting base plate detachably mounted on a workbench, multiple lifting cylinders detachably mounted on the upper side of the lifting base plate, a lifting upper plate detachably mounted on the output shaft of each lifting cylinder, multiple lifting guide columns detachably mounted on the lower side of the lifting upper plate, and multiple lifting guide sleeves detachably mounted on the upper side of the lifting base plate. The lifting guide columns are correspondingly slidably inserted into the lifting guide sleeves. The carrier lifting assembly lifts and positions the loading vehicle, while a feeding assembly feeds the full-loaded carrier to the appropriate position. This lifting platform has a limited function, merely solving the problem of the original placement platform being too high, making it inconvenient for personnel placement. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing flexible circuit boards being unable to be fixed or assisted in removal by providing an automatic ejection mechanism.

[0005] To achieve the above technical objectives, the following technical solution is provided: an automatic ejection mechanism for a flexible circuit board, including an operating table, on which a flexible circuit board support platform is mounted. The flexible circuit board support platform is composed of several support units, wherein the support unit includes a lifting cylinder mounted on the operating table, a support plate fixed above the lifting cylinder, and several evenly distributed air plate mechanisms for fixing the flexible circuit board are provided inside the support plate.

[0006] A flexible circuit board mounting plate is provided above the operating table. The flexible circuit board mounting plate is provided with several second through holes through which the air plate mechanism passes. The air plate mechanism has a second bracket fixed under the support plate.

[0007] In one feasible embodiment, the control panel includes an overall frame, an auxiliary support box located at the bottom of the overall frame, an auxiliary reinforcing bracket located in the middle of the overall frame, and a suspension bracket located at the top of the overall frame; wherein the auxiliary reinforcing bracket is located between the support plate and the auxiliary support box; and a lifting cylinder is provided on the auxiliary support box.

[0008] In one feasible implementation, the pneumatic disc mechanism has four parts, each with a suction cup structure at its end;

[0009] The flexible circuit board mounting plate has four receiving cavities; the receiving cavities cooperate with the suction cup structure, and the suction cup structure is located inside the receiving cavities, with the top of the suction cup structure flush with the upper surface of the flexible circuit board mounting plate.

[0010] In one feasible implementation, the support unit has four members, whose length sides are closely connected to each other and whose width sides are closely fitted to the operating table.

[0011] In one feasible implementation, the flexible circuit board support platform includes an operating table located on an operating platform, on which channels are formed, and four flexible circuit board mounting plates are placed within the channels.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The multi-cylinder design of this application provides smoother operation and reduces off-center loading compared to a single-cylinder design. Each cylinder can be controlled individually or in combination. This cylinder design enables the support plate to achieve a positioning accuracy of ±0.1mm within the control panel. The modular design of the support unit reduces the overall failure rate and facilitates the maintenance and replacement of individual cylinders. The support plate and its combinations can accommodate different types of flexible circuit boards. The design of this application achieves high synergy with assembly line components. The lifting height is precisely matched with the pick-and-place components. Attached Figure Description
