Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly devices, and in particular to an automatic disassembly and assembly device for circuit boards and carriers. Background Technology

[0002] With the development of science and technology, display devices such as mobile phones, tablets, laptops and televisions are ubiquitous in people's lives. Most existing display devices use liquid crystal displays (LCDs). In LCDs, flexible printed circuit boards (FPCs) are used to connect to electrodes on the substrate in order to transmit signals. For recycled LCDs, the FPCs can be disassembled and reused.

[0003] For example, Chinese utility model patent CN204893131U discloses "a circuit board disassembly fixture, comprising: a base; a positioning frame fixed on the base for clamping and fixing a display screen to be disassembled; lifting guide columns fixed on the base and located on both sides of the positioning frame; a heating head fixedly connected to the lifting guide columns for moving up and down along the lifting guide columns, and the heating head being located above the positioning frame for contacting the circuit board of the display screen to be disassembled for heating; and a vacuum adsorption hole formed in the heating head for adsorbing the circuit board through vacuum when the heating head is in contact with the circuit board, thereby driving the circuit board to move up and down with the heating head." However, a limitation of this design is that the positioning frame, due to the limitation of the base size, can only be adapted to a fixed-size display screen, reducing the versatility and flexibility of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: an automatic assembly and disassembly device for circuit boards and carriers, including a frame 1, a sliding frame 11 slidably arranged on the vertical end of the frame 1, a second slide rail 12 fixedly connected to the vertical end of the frame 1, a second slider 15 slidably fitted on the second slide rail 12, the second slider 15 being fixedly connected to the vertical end of the sliding frame 11, a second electric telescopic rod 13 fixedly installed on the vertical end of the sliding frame 11, the free end of the second electric telescopic rod 13 being fixedly connected to the vertical end of the frame 1, the second electric telescopic rod 13 controlling the sliding frame 11 to slide left and right along the second slide rail 12, adjusting the position of the heating plate 7 and the flexible printed circuit board 6 adsorbed by the suction nozzle 16.

[0017] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, a heating plate 7 is vertically slidably mounted on the horizontal end of the sliding frame 11. The flexible printed circuit board 6 in the bezel area of ​​the display screen 5 is connected to the bezel area of ​​the display screen 5 by anisotropic conductive adhesive. The heating plate 7 locally heats the adhesive area between the flexible printed circuit board 6 and the bezel area of ​​the display screen 5, softening or melting the adhesive layer for easy separation. A cavity plate 8 is fixedly connected to the heating plate 7. A first electric telescopic rod 10 is fixedly installed on the horizontal end of the sliding frame 11. A sleeve 19 is fixedly connected to the middle of the cavity plate 8. The free end of the first electric telescopic rod 10 passes through the sleeve 19 and connects with the heating plate 7. The heating plate 7 is fixedly connected, and guide rods 9 passing through the horizontal end of the sliding frame 11 are fixedly connected around the top of the heating plate 7. The heating plate 7 is driven to move up and down by the first electric telescopic rod 10. When heated, it comes into contact with the flexible printed circuit board 6, which softens the adhesive material. A negative pressure pipe 14 is fixedly connected to one side of the cavity plate 8. A negative pressure pump is connected to the free end of the negative pressure pipe 14. Several suction nozzles 16 passing through the heating plate 7 are fixedly connected to the bottom of the cavity plate 8. The vacuum suction force is formed by evacuating air through the negative pressure pipe 14, which firmly adsorbs and fixes the flexible printed circuit board 6, ensuring that the flexible printed circuit board 6 will not shift or be damaged during disassembly.

[0018] Specifically, such as Figure 1 and Figure 5 As shown, symmetrically arranged clamps 4 are provided on the horizontal end of the frame 1. A first slide rail 2 is fixedly connected to the horizontal end of the frame 1. First sliders 3 are slidably fitted on both sides of the first slide rail 2. The clamps 4 are fixedly connected to the first sliders 3 on the same side. A third electric telescopic rod 17 is fixedly connected to the bottom side of the vertical end of the frame 1. Two sets of connecting rods 18 are rotatably connected to the free end of the third electric telescopic rod 17. The free end of the connecting rods 18 is rotatably connected to the clamps 4 on the same side. The clamps 4 are arranged below the heating plate 7. Several slots 401 are opened on the clamps 4. The display screen 5 is placed in the slots 401. The third electric telescopic rod 17 drives the clamps 4 to open and close through the two sets of connecting rods 18, realizing the action of clamping or releasing the display screen 5, adapting to various sizes of display screens 5 and improving versatility.

[0019] Working principle: In use, the display screens 5 with flexible printed circuit boards 6 are placed one by one, facing upwards, into the slots 401 on the clamps 4 directly below the heating plate 7. The free end of the third electric telescopic rod 17 is driven to retract, thereby driving the clamps 4 to close together via the two sets of connecting rods 18, clamping the display screens 5. Then, the first electric telescopic rod 10 is driven to move the heating plate 7 downwards to contact the flexible printed circuit board 6, starting to heat and soften the adhesive layer. When the temperature reaches the set value, the negative pressure pump is activated, supplying negative pressure to the suction nozzle 16 through the negative pressure pipe 14, adsorbing the flexible printed circuit board 6. Subsequently, the first electric telescopic rod 10 moves in the opposite direction, driving the heating plate 7 and the adsorbed flexible printed circuit board 6 to adhere to the suction nozzle 16. The circuit board 6 moves upward together. As the heating plate 7 rises, the flexible printed circuit board 6 is gradually peeled off from the surface of the display screen 5, completing the disassembly. The peeled flexible printed circuit board 6 is held below the heating plate 7 by the suction nozzle 16, waiting for subsequent manual or robotic removal. After disassembly, all actuators are reset, the clamp 4 is released, and the display screen 5 is removed. Then, the new flexible printed circuit board 6 is adsorbed below the suction nozzle 16, lowered, and attached to the electrode area of ​​the display screen 5 to complete the assembly. This device integrates multiple technologies such as heating and softening, vacuum adsorption, clamping and positioning, and linkage control, which can efficiently and safely complete the disassembly and assembly of the flexible printed circuit board 6 and the display screen 5.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
