Description

Technical Field

[0001] The utility model relates to the technical field of FPC processing, in particular to a pre-pressing device for FPC cable processing. Background Art

[0002] An FPC is a flexible printed circuit board, usually made of polyester film or polyimide film, and has the characteristics of flexibility, lightness, thinness, etc. It is usually used to connect various components in electronic devices, such as connectors, LED lights, LCD screens, etc. The FPC cable can be customized according to the shape and size of the device, so it is widely used in electronic products such as mobile phones, tablet computers, digital cameras, etc.

[0003] After retrieval, a screen FPC cable automatic pre-pressing device with the authorization announcement number of CN220105462U includes a fixed base, a lifting device arranged on the fixed base, a heating component connected to the output end of the lifting device, an infrared temperature control device arranged on the fixed base and used to detect the temperature on the outer surface of the heating component, and the infrared temperature control device is electrically connected to the lifting device. The screen FPC cable automatic pre-pressing device of the present application can avoid the situation of too high or too low temperature of the heating component by adding an infrared temperature control device, and improve the stability and consistency of the pre-pressing process.

On one side of each of the two clamping assemblies 22 away from each other, a pushing assembly 23 is provided for adjusting the clamping assembly 22.

[0041] Further, the clamping assembly 22 includes an empty column 221 for connecting various components. The empty column 221 is fixedly connected to the pipeline 2. A clamping block 222 is slidably connected to the inner wall of the empty column 221 for clamping with the suction plate 31. A first spring 223 is fixedly connected between the inner wall of the clamping block 222 and the empty column 221 for assisting the clamping block 222 to reset.

[0042] Furthermore, the pushing assembly 23 includes a push block 231 for pushing the clamping block 222. A connecting rod 232 is fixedly connected to the side of the push block 231 away from the clamping block 222 for connecting the push plate 233 and the connecting plate 234.

[0045] Working principle: When in use, turn on the device. The suction pump 4 will provide suction for the suction plate 31 through the pipeline 2. Then, place the FPC to be processed on the suction plate 31. The suction plate 31 will provide suction holes 32 to adsorb it. Then, turn on the heating element 92. The heating element 92 will heat the pressing block 93. The infrared temperature control device 10 will monitor the temperature of the pressing block 93. When the extrusion assembly 9 reaches the preset temperature, turn on the electric slide rail 6. The electric slide rail 6 will drive the slider 7 to move downward. When it reaches the appropriate position, turn on the electric push rod 8. The electric push rod 8 will press the extrusion assembly 9 downward, so that the pressing block 93 processes the FPC on the suction plate 31. After the processing is completed, control the electric slide rail 6 through the circuit to drive the slider 7 to move upward, so that the electric push rod 8 drives the extrusion assembly 9 to rise. Then, turn off the suction pump 4 and remove the FPC.

[0046] When it is necessary to replace the fixing component 3 of different sizes, push the push plate 233 inward, so that it drives the connecting rod 232 to move inward, so that the connecting rod 232 drives the push block 231 to move in the push groove 36 and squeeze the clamping block 222, so that it retracts into the hollow column 221. Then, rotate the suction plate 31, so that the clamping component 22 slides in the chute 34 until it moves to the connection port 33. Then, lift the entire fixing component 3 upward to separate it from the pipeline 2. Then, release the push plate 233. With the assistance of the second spring 235, the connecting plate 234 will drive the connecting rod 232, the push block 231 and the push plate 233 to reset. Then, push the clamping block 222 into the hollow column 221 by hand. Then, align the fixing component 3 to be used with the pipeline 2, so that its connection port 33 is aligned with the clamping component 22. Then, press the suction plate 31 downward, so that the clamping component 22 enters the chute 34. Then, rotate the suction plate 31, so that the clamping component 22 moves to the clamping groove 35. The clamping block 222 will reset and be clamped with the clamping groove 35 with the assistance of the first spring 223.
