Technical Field

[0001] The utility model relates to the technical field of flexible circuit boards, in particular to a fixture for drying flexible circuit boards. Background Art

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher-density installations, and also help reduce assembly processes and enhance reliability. After completing the cover film lamination process, flexible circuit boards are printed, dried, exposed, and developed in a continuous manner.

[0003] Currently, when drying flexible circuit boards, they are usually placed in a drying box for drying. Users are time-consuming and laborious when placing and taking out the circuit boards, and need to reach into the device to take and place them, which poses certain safety hazards. In addition, the airflow in the existing drying fixture is unstable, and the circuit boards in the device cannot be heated evenly, resulting in low drying efficiency. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the utility model provides a jig for drying flexible circuit boards.

[0005] The embodiment of the present invention provides a jig for drying a flexible circuit board, comprising:

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the present invention provides a fixture for drying flexible circuit boards, comprising:

[0022] The shell body 1 has a plurality of columns 2 fixedly connected to the lower end surface of the shell body 1, and the lower end surfaces of the plurality of columns 2 are provided with pads 15. The setting of the pads 15 improves the stability of the device. The shell body 1 is provided with a heat-insulating door 3. The shell body 1 is provided with a plurality of bearing components and a plurality of fixing components, and the plurality of fixing components are respectively arranged on the plurality of bearing components; a drying component; the drying component includes an air cavity 4 arranged on the shell body 1, and a hot air blower 5 is fixedly connected to one side wall of the shell body 1. The hot air blower 5 is a prior art that can heat the external air and then discharge it into the air cavity 4. It will not be described in detail here. The air outlet end of the hot air blower 5 is connected to the ventilation cavity 4. The inner wall of the air cavity 4 away from the hot air blower 5 is provided with a plurality of air outlet holes 6, and the inner wall of the air cavity 4 is provided with a plurality of heating plates and heating rods;

[0023] The heating plate and the heating rod are existing technologies and can heat the gas in the air cavity 4. They will not be described in detail here. The upper end surface of the shell 1 is penetrated by an exhaust pipe 7. The carrying assembly includes two slide rails 8 fixedly connected to the side wall of the shell 1. The two slide rails 8 are slidably connected to a loading plate 9. A plurality of loading plates 9 are fixedly connected with a handle 16 to facilitate the user to take and push the loading plates 9, thereby improving the portability of the device. A plurality of loading plates 9 are provided with a plurality of air holes to facilitate the passage of hot air through the loading plates 9, thereby improving the circulation of the gas in the device.

[0024] The fixed component includes a sliding cavity 10 arranged on the shell 1, and a plurality of spring frames 11 are fixedly connected to the inner wall of the sliding cavity 10 on the side away from the loading plate 9. A sliding plate 12 is slidably connected in the sliding cavity 10, and a plurality of spring frames 11 are fixedly connected to the sliding plate 12. A card block 13 is fixedly connected to the sliding plate 12, and the card block 13 is conically arranged. The card block 13 slides through the shell 1, and a card slot is provided on the loading plate 9. The card block 13 and the card slot are matched. A moving cavity is provided on the shell 1, and a moving plate 14 is slidably connected in the moving cavity. The moving plate 14 is made of metal. An electromagnet is provided on the inner wall of the moving cavity on the side away from the loading plate 9. The electromagnet is existing technology and will not be repeated here. A connecting rod slides through the shell 1, and the two ends of the connecting rod are respectively fixedly connected to the moving plate 14 and the sliding plate 12.

[0025] The detailed working process of this utility model is as follows:

[0026] The user places the device in the designated workplace, first places the circuit board to be dried on the carrier plate 9, and then places the carrier plate 9 on the slide rail 8. At this time, the user pushes the carrier plate 9 through the handle 16. The carrier plate 9 will squeeze the block 13 during the sliding process, so that the block 13 is pushed, and the spring frame 11 located in the sliding cavity 10 contracts, so that the block 13 is temporarily moved into the sliding cavity 10. When the carrier plate 9 moves to the designated position, the slot on the carrier plate 9 will face the block 13. At this time, the block 13 loses its restriction, and the spring frame 11 will drive the block 13 to automatically move into the slot, thereby automatically fixing the carrier plate 9, preventing the carrier plate 9 from moving, and improving the loading efficiency during the drying process. The stability of the material board 9 is ensured, and then the user closes the thermal insulation door 3 for drying. First, the hot air blower 5 heats the outside air and blows it into the air cavity 4. At the same time, the heating plate and the heating rod work at the same time to heat the gas in the air cavity 4 again. The heated gas is discharged through the air outlet 6 to dry the circuit board on the material carrier 9, so that the circuit board is heated more evenly, and the airflow in the shell 1 is stable, which effectively improves the drying efficiency. When the drying work is completed, the user opens the thermal insulation door 3. At this time, the electromagnet starts to work, and the electromagnet attracts the movable plate 14, so that the card block 13 is automatically moved out of the card slot. The user can take out the material carrier 9, which is convenient for the user to place and take the circuit board, thereby improving the portability of the device.
