Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to an FPC multi-layer stacking pressing device. Background Art

[0002] Flexible printed circuit boards (FPCs) are highly reliable and highly flexible printed circuit boards (PCBs). They feature high wiring density, light weight, thinness, and excellent bendability. They can move and expand in three dimensions, enabling three-dimensional wiring. This improves the integration of component assembly and connections, reduces product size, and maintains high stability. Therefore, FPCs are widely used in industries such as mobile phones, computers, mobile peripherals, and automotive electronics. The production of multilayer FPCs requires lamination to bond multiple single- or double-sided boards together. However, traditional lamination equipment can only press one product at a time, resulting in poor efficiency. Utility Model Content

[0003] Based on this, it is necessary to provide an FPC multi-layer stacking pressing device to address the shortcomings of the existing technology.

[0005] Furthermore, the pushing piece is arranged in a horizontal sheet shape, and the two pushing pieces push the copper foil in the same direction from both sides of the copper foil at the same time.

[0006] Furthermore, the push piece is arranged in a vertical sheet shape, and the inner side of the push piece limits the product and the upper and lower copper sheets.

[0007] Furthermore, it also includes a frame and a pre-pressing device, wherein the pre-pressing device and the pressing device are both arranged on the frame, and the pre-pressing device is arranged on the front side.

[0008] Furthermore, it also includes a conveying device, which is arranged between the pressing device and the pre-pressing device.

[0009] Furthermore, it also includes a cooling device, which is arranged between the pressing device and the pre-pressing device.

[0010] Furthermore, it also includes a clamping manipulator, which is arranged on the outside of the secondary pressing device.

[0011] In summary, the present invention, by providing a pre-pressing device and then performing the press, can initially vent the laminated laminated products, ensuring better tightness during subsequent pressing. It can also press multiple products at once, increasing work efficiency. Furthermore, by providing a copper foil layer for separation, loading can be done directly from the left and right sides, which is relatively convenient. Furthermore, the design of the push arm can guide and flatten the copper foil while also serving as a positioning mechanism, improving the accuracy of the stacking process. This utility model is highly practical and has strong promotional significance. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figures 1 to 4 As shown, the utility model provides an FPC multi-layer stacking pressing device, which includes a frame 10 and a conveying device 20, a pre-pressing device 30, a cooling device 40, and a secondary pressing device 50 arranged on the frame 10. The pre-pressing device 30 is arranged at the front end of the conveying device 20, the secondary pressing device 50 is arranged at the rear side of the pre-pressing device 30, and the cooling device 40 is arranged between the secondary pressing device 50 and the pre-pressing device 30.

[0018] The pre-pressing device 30 includes a lower pressing mold 31 and an upper pressing mold 32 disposed above the lower pressing mold 31. The pre-pressing mold is a conventional pressing device. In this embodiment, the pre-pressing device 30 performs only preheating and pressing during pressing to achieve initial adhesion between the layers, thereby expelling air between the layers and facilitating a tighter bond between the layers during the secondary pressing. The cooling device 40 is provided with a cooling device whose internal temperature is lower than the external temperature. When the product passes through the cooling device 40 after pre-pressing, it cools the product, allowing the preheated and pressed product to be quickly and initially fixed.

[0019] The secondary pressing device 50 includes a pressing mold, a copper foil 51 and two push arms 52. The pressing mold includes an upper mold 53 and a corresponding lower mold 54. The pressing mold is a conventional hot pressing mold. The top of the copper foil 51 is fixed to the bottom surface of the upper mold 53, and the bottom end is fixed to the top surface of the lower mold 54, with a bending area formed in the middle. The two push arms 52 are respectively arranged on the left and right sides of the lower mold 54 and are located on both sides of the copper foil 51. The bottom end of the push arm 52 is provided with a moving device and a lifting device. The moving device can drive the push arm 52 to move forward and backward and left and right, and the lifting device drives the push arm to move up and down. In this embodiment, the moving device is a conventional structure, for example, it can be achieved by a cylinder pushing the push arm 52 to move along the guide rail. The lifting device is a cylinder that pushes the push arm upward and moves it up and down, which is also a conventional structure. Therefore, its specific structure will not be described in detail here. The inner end of the push arm 52 is provided with a push piece 55. In addition, a material clamping robot is also required, which is used to move the lower copper plate, the pre-pressed product, and the upper copper plate from the material frame and the conveying device 20 to the copper foil 51 of the lower mold 54 in sequence.

[0020] During operation, one of the pushing arms 52 folds the pushing piece 55 and pushes it from the bottom end of the copper foil 51 toward the other side to make the bottom surface flat. When it moves to the required position, the robot moves the lower copper plate onto the copper foil 51, and the inner surface of the lower copper plate contacts the outer side of the pushing piece 55, and the pushing piece 55 limits the lower copper plate. Then the pre-pressed product and the upper copper plate are stacked on the lower copper plate in turn. The pushing piece 55 withdraws backward and moves to the other side of the copper foil 51, moves inward to push the copper foil 51 toward the side of the upper copper plate, and then stacks the second layer on the copper foil 51 pressed on the upper copper plate; repeat this until the copper foil 51 between the upper mold 53 and the lower mold 54 is stacked. Finally, the upper mold 53 presses downward, and multiple products can be pressed at one time. The copper foil 51 is a high-temperature resistant material, which can play a separating role.

[0021] In summary, the present invention provides a pre-pressing device 30 and then performs pressing, which can preliminarily exhaust the laminated laminated products, thereby improving the tightness during subsequent pressing. Furthermore, multiple products can be pressed at a time, resulting in high work efficiency. Furthermore, by providing a layer of copper foil 51 for separation, loading can be performed directly from the left and right sides, which is relatively convenient. Furthermore, the design of the push arm 52 can guide and flatten the copper foil 51, while also serving as a positioning function, thereby improving the accuracy of the stacking. The present invention is highly practical and has a strong promotional significance.

[0022] The above-described embodiments represent only two implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
