Description

Technical Field

[0001] The utility model relates to the technical field of circuit board drying, and more specifically, to a drying device for flexible circuit board production. Background Art

[0002] Circuit board drying generally refers to drying the moisture adhering to the outer side wall of a flexible circuit board; if there is a large amount of moisture adhering to the outer side wall of the flexible circuit board and it is not dried, it will cause multiple flexible circuit boards to stick to each other and even cause damage. In the prior art, the drying device for flexible circuit board production consists of a fixing device and a drying device, and is often used to dry the flexible circuit board after fixing. In the existing drying device for flexible circuit board production, when drying the flexible circuit board to be dried during operation, due to poor fixing effect, the flexible circuit board to be dried falls off the top of the placement drying board, resulting in the flexible circuit board to be dried adhering to the inner side wall of the drying device body, thus increasing the difficulty of taking out the flexible circuit board to be dried.

[0003] In view of the above problems, regarding the technical problems, after a large amount of retrieval, a drying device for flexible circuit board production with the patent number 202223605965.2 was found, which belongs to the technical field of circuit board drying, and includes a drying device body; a drying air pump is fixedly connected to the top of the drying device body; an exhaust pipe is fixedly connected to the bottom of the drying air pump; the exhaust pipe is arranged inside the drying device body; during operation, the drying gas passes through the inside of the placement drying board, and dries the bottom of the flexible circuit board to be dried through the first drying holes; the overall device improves the drying effect of the moisture at the bottom of the flexible circuit board to be dried; because the pressing fixing plate fixes the top of the flexible circuit board to be dried; thus, the overall device reduces the situation that when drying the flexible circuit board to be dried, due to poor fixing effect, the flexible circuit board to be dried falls off the top of the placement drying board, resulting in the flexible circuit board to be dried adhering to the inner side wall of the drying device body, thus increasing the difficulty of taking out the flexible circuit board to be dried. However, the technical solution provided by this patent has the following problems: when using this device, the circuit board is placed on the placement drying board for drying, and then hot air is introduced into the device through the exhaust pipe, and then the circuit board is dried. The exhaust pipe is located above the placement drying board, and the hot air is concentrated and sprayed out from the exhaust pipe, resulting in uneven heating of the circuit board, thus causing uneven drying and further reducing the drying efficiency.

[0004] The utility model can make the circuit board dry more evenly. Summary of the Utility Model

The circuit board main body 5 is limited by the clamping assembly 4, and the setting of the state of the grid plate 402 does not affect the drying when the circuit board main body 5 is limited, further improving the drying efficiency of the circuit board main body 5. When drying, the water dripping from the circuit board main body 5 directly falls on the bottom end inside the box body 1, and the middle part of the bottom end is concave inward, so that the water gathers at the lowest part of the bottom end, and then enters the internal collection box through the drain pipe. When the collection box is full and needs to be cleaned, the corresponding box door is opened for treatment, making the device more flexible and convenient to use.

[0025] In the embodiment of the present utility model, a groove 301 is arranged inside the limiting frame 3, and the clamping assembly 4 is located inside the groove 301.

The hollow limiting frame 3 does not affect the drying of the circuit board main body 5 by hot air when limiting it. The groove 301 is used to limit the clamping assembly 4, and then the screw rod 302 is used to further limit the clamping assembly 4, effectively preventing the clamping assembly 4 from falling off from the inside of the groove 301 when the device is in use, making the device more stable when in use. The embedded connection method is not only flexible, but also improves the drying stability of the circuit board main body 5 to a certain extent.

One side of the limiting frame 3 is further supported by the limiting rod 305, making the limiting frame 3 more stable and not easy to fall off when rotating. While the motor 304 drives the limiting frame 3 to rotate, the dryer 2 is used to synchronously convey hot air to dry the circuit board main body 5, making the drying of the circuit board main body 5 more uniform, and thus effectively improving the drying efficiency of the device.

[0027] In the embodiment of the present utility model, an exhaust pipe 201 is provided at the output end of the dryer 2, and the exhaust pipe 201 penetrates through the top of the box body 1 and is embedded therein.

The exhaust holes are used to disperse the hot air, effectively preventing the accumulation of hot air, making the circuit board body 5 more evenly dried during drying, and further improving the drying efficiency of the device.

[0028] In the embodiment of the present utility model, a plurality of card holes 403 are opened in the positioning plate 401. The upper and lower edges of the positioning plate 401 are connected to two grid plates 402 by hinges, and the positioning plate 401 is located between the two grid plates 402. The circuit board body 5 is embedded in the card holes 403. Among them, a bolt 404 is arranged through one end of the grid plate 402. Threaded holes 405 are opened at both ends of the positioning plate 401, and the positions of the threaded holes 405 correspond to those of the bolts 404, and the bolts 404 are embedded in the threaded holes 405.

The circuit board body 5 is placed into the card holes 403, and the circuit board body 5 is supported by one grid plate 402. After all the circuit board bodies 5 are placed into the card holes 403, the other grid plate 402 is connected to the positioning plate 401 to limit the upper end of the positioning plate 401, and then the grid plate 402 is connected to the positioning plate 401 by embedding the bolts 404 into the threaded holes 405, further limiting the circuit board main body, making the circuit board body 5 more stable during drying, and thus improving the stability of the device during drying.

Then the clamping assembly 4 is placed into the interior of the limiting frame 3, and the clamping assembly 4 is further limited by the screw rod 302, effectively preventing the clamping assembly 4 from falling off from the interior of the groove 301 during the use of the device. The hot air generated by the dryer 2 is introduced into the interior of the auxiliary pipe 202 through the exhaust pipe 201, and then sprayed out through the exhaust holes of the auxiliary pipe 202. The exhaust holes are used to disperse the hot air. At the same time, the motor 304 drives the rotating rod 303 to rotate, thereby driving the limiting frame 3 to rotate by the rotating rod 303.
