[0002] PCB flexible circuit boards are often used in foldable mobile phones, wearable devices, automotive electronics, medical instruments and other scenarios. Their function is to use their bendable characteristics to achieve circuit connections in a compact space, reduce equipment weight, adapt to dynamic bending requirements, and support high-density wiring and multi-layer design. It improves signal transmission stability and simplifies assembly processes. They are widely used in electronic equipment with high requirements for volume and reliability.

[0003] In actual work, the existing PCB flexible circuit board folding assembly equipment can meet the basic requirements of PCB flexible circuit board assembly by using positioning fixtures and robotic arms, but there are still the following problems:

[0004] The common computer PCB flexible circuit board folding assembly equipment in current technology is usually equipped with a special mold for fixing the position of the motherboard. However, in actual work, when different models of motherboards and flexible circuit boards need to be assembled, the mold inevitably needs to be replaced and debugged, which affects work efficiency. For this reason, the present application provides a PCB flexible circuit board folding assembly equipment to meet the needs. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and provide a PCB flexible circuit board folding assembly device.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a PCB flexible circuit board folding and assembly device, comprising a base and a processing table arranged on the top of the base, and further comprising:

[0007] A drive assembly, the drive assembly comprising a mounting seat disposed in an inner cavity of the base, a push rod connected to the bottom of the mounting seat, a first connecting plate connected to the bottom of the push rod, a second connecting plate disposed on the side of the first connecting plate, a slider disposed on the top of the second connecting plate, and a telescopic rod disposed on the top of the slider;

[0008] A positioning assembly, the positioning assembly comprising a first support rod mounted on the top of the processing table, the top of the first support rod being connected to a protective shell, and the top of the protective shell being provided with a flexible roller;

[0010] Furthermore, the inner cavity of the second connecting plate is connected to a third connecting plate, and the top of the third connecting plate is connected to the bottom of the slider.

[0011] The technical effect of adopting the above technical solution is: through the cooperation of the second connecting plate and the third connecting plate, the slider can be driven to perform translational movement when the push rod performs lifting movement.

[0012] Furthermore, a sliding rod is connected to the side of the telescopic rod, and a first fixing plate is connected to the top of the inner cavity of the base.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 - Figure 7 As shown, this embodiment provides a technical solution: a PCB flexible circuit board folding assembly device, including a base 1 and a processing table 11 arranged on the top of the base 1, and also includes:

[0032] The drive assembly 2 includes a mounting base 21 disposed in the inner cavity of the base 1. The bottom of the mounting base 21 is connected to a push rod 22. The bottom of the push rod 22 is connected to a first connecting plate 23. A second connecting plate 24 is disposed on the side of the first connecting plate 23. A slider 26 is disposed on the top of the second connecting plate 24. A telescopic rod 27 is disposed on the top of the slider 26.

[0033] The positioning assembly 3 includes a first support rod 31 mounted on the top of the processing table 11. The top of the first support rod 31 is connected to a protective shell 32. The top of the protective shell 32 is provided with a flexible roller 36.

[0034] The auxiliary component 4 includes a touch block 41 installed on the top of the telescopic rod 27, and a flexible gasket 43 is connected to the side of the touch block 41. The inner cavity of the second connecting plate 24 is connected to the third connecting plate 25, and the top of the third connecting plate 25 is connected to the bottom of the slider 26. The side of the telescopic rod 27 is connected to the sliding rod 28. The top of the inner cavity of the base 1 is connected to the first fixed plate 210, and the side of the first fixed plate 210 is provided with a first sliding groove 29. One end of the sliding rod 28 extends to the inner cavity of the first sliding groove 29, and one end of the sliding rod 28 is slidably connected to the inner cavity of the first sliding groove 29. By providing the mounting seat 21, the push rod 22 and the first connecting plate 23 can be supported. By providing the push rod 22, the first connecting plate 23 can be actively driven to drive the second connecting plate 24 to move up and down. When the first connecting plate 23 drives the second connecting plate 24 to move downward, the end of the third connecting plate 25 away from the second connecting plate 24 is rotated along the end of the third connecting plate 25 and the inner cavity of the second connecting plate 24. The clockwise movement can cause the third connecting plate 25 to drive the slider 26 to move along the top of the base 1 of the mounting seat 21. The mounting seat 21 base 1 and the mounting seat 21 driving assembly 2 cooperate to limit the movement trajectory of the slider 26 to prevent the position of the slider 26 from being offset. During the movement of the slider 26, the telescopic rod 27 drives the slide bar 28 to move synchronously along the inner cavity of the first slide groove 29. When the telescopic rod 27 moves to a certain position, the slide bar 28 cooperates with the first slide groove 29 to cause the telescopic rod 27 to stretch upward as a whole, thereby achieving the effect of driving the touch block 41 to gradually rise during the translation process. When the touch block 41 moves to a certain position, the side of the touch block 41 contacts the side of the main board, and the top of the touch block 41 contacts the bottom of the flexible circuit board, thereby achieving the effect of fixing the position of the main board while slightly pushing one end of the flexible circuit board upward, effectively improving work efficiency and facilitating subsequent folding and assembly processing.

[0035] Furthermore, Figure 3-Figure 5As shown: a second slide groove 34 is provided on the top of the protective shell 32, and the inner cavity of the second slide groove 34 is slidably connected to the second fixing plate 33, the top of the second fixing plate 33 is connected to the second support rod 35, and the top of the second support rod 35 is connected to the flexible roller 36. The bottom of the inner cavity of the protective shell 32 is connected to the wheel disc 38, and the top of the wheel disc 38 is provided with a first groove 39. The top of the protective shell 32 is provided with a guide groove 37. A small driving motor is provided at the bottom of the wheel disc 38. The shape of the first groove 39 is designed to be arc-shaped. By setting the protective shell 32, the second fixing plate 33 and the wheel disc 38 can be protected. By starting the small driving motor, the output shaft of the motor rotates forward, thereby driving the wheel disc 38 When the wheel 38 moves clockwise, the inner wall of the first groove 39 contacts the outer surface of the second support rod 35, thereby prompting the second support rod 35 to drive the flexible roller 36 to move toward the middle of the protective shell 32. When the flexible roller 36 moves to a certain position, the side of the flexible roller 36 contacts the side of the main board, thereby preliminarily positioning the position of the main board to ensure that the position of the main board remains centered, which is convenient for the subsequent auxiliary component 4 to fix the position of the main board and the flexible circuit board on the top of the main board. During the movement of the second support rod 35, the second fixing plate 33 and the second slide groove 34 cooperate to limit the movement trajectory of the second support rod 35.

[0036] Furthermore, Figure 4 and Figure 7 As shown: In this solution, a second groove 42 is provided on the top of the touch block 41, and the flexible gasket 43 is made of flexible rubber. The second groove 42 provided on the top of the touch block 41 facilitates the subsequent folding of the flexible circuit board. At the same time, the flexible gasket 43 is fixedly connected to the side of the touch block 41, so that when the side of the touch block 41 contacts the side of the motherboard, the stress generated by the contact can be buffered to avoid damage to the motherboard.

[0037] Working principle:

[0038] like Figure 1-7 As shown:

[0039] During use: first, place the prepared motherboard and flexible circuit board on the top of the protective shell 32, then start the small drive motor provided at the bottom of the protective shell 32, and the output shaft of the motor rotates forward, thereby prompting the wheel 38 to move clockwise, and through the cooperation between the wheel 38 and the first groove 39, the second support rod 35 can drive the flexible roller 36 to move along the inner cavity of the guide groove 37 toward the middle of the protective shell 32. When the second support rod 35 moves to a certain position, the side of the flexible roller 36 contacts the side of the motherboard, thereby preliminarily positioning the position of the motherboard. After the positioning is completed, start the push rod 22, thereby prompting the first connecting plate 23 to drive the second connecting plate 23 to move clockwise. The connecting plate 24 moves downward, thereby enabling the slider 26 to move along the top of the base 1 of the mounting seat 21 through the third connecting plate 25. During the movement of the slider 26, the first slide groove 29 and the slide rod 28 cooperate to cause the telescopic rod 27 to stretch, thereby enabling the touch block 41 to gradually move upward while approaching the middle of the processing table 11. When the touch block 41 moves to a certain position, the inner cavity of the second groove 42 contacts the bottom of the flexible circuit board. At the same time, the side of the flexible gasket 43 contacts the side of the main board, thereby fixing the position of the main board and the flexible circuit board, thereby facilitating subsequent folding and assembly processing.

[0040] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
