DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 3 As shown, the circuit board drying equipment provided in the embodiment of the present application includes a frame 100, a drying chamber 200, a transport channel 900, a herringbone bracket 500 and a baffle 600, wherein the frame 100 is a supporting structure of the drying equipment, and in the present embodiment, the frame 100 is a floor-standing frame. The drying chamber 200 is arranged on the frame 100, and the drying chamber 200 is a structure with a chamber inside, and the drying chamber 200 has an inlet 210 and an outlet 220. In actual use, the circuit board can enter the drying chamber 200 from the inlet 210, and realize the drying process in the drying chamber 200, and finally leave the drying chamber 200 through the outlet 220.

[0028] A driving motor 300 is fixedly installed on the upper surface of the top plate of the drying bin 200. The driving motor 300 is vertically arranged on the upper surface of the top plate of the drying bin 200. The driving shaft of the driving motor 300 passes through the top plate of the drying bin 200 and extends into the drying bin 200. The driving shaft of the driving motor 300 is located at the end of the drying bin 200 and is fixedly connected to a drying fan 400. Therefore, the driving motor 300 can drive the drying fan 400 to rotate, thereby achieving drying of the circuit boards in the drying bin 200.

[0029] Preferably, a plurality of drive motors 300 are disposed on the upper surface of the top plate of the drying chamber 200, and the plurality of drive motors 300 are arranged equidistantly along the length direction of the drying chamber 200. In some embodiments, the center line of the plurality of drive motors 300 coincides with the center line of the width direction of the drying chamber 200. Each drive motor 300 is correspondingly connected to a drying fan 400, so that the drying chamber 200 can have a stronger drying treatment effect.

[0030] The transport channel 900 is horizontally arranged on the frame 100. The transport channel 900 enters the drying chamber 200 from the feed inlet 210 and passes through the interior of the drying chamber 200 and extends toward the feed inlet 210. The herringbone bracket 500 is arranged on the upper surface of the transport channel 900. Figure 2 As shown, the herringbone support 500 includes two inclined plates 510, each of which is provided with a roller conveyor belt 520, and the roller conveyor belt 520 is used to transport the circuit board. Preferably, the length of the roller conveyor belt 520 is adapted to the length of the transport channel 900.

[0031] In this embodiment, the baffle 600 is a structure vertically arranged on the upper surface of the transport channel 900, the baffle 600 is located beside the inclined plate 510, and a water storage tank 700 is formed between the baffle 600 and the inclined plate 510. When the circuit board is placed obliquely on the roller conveyor belt 520, the etching liquid remaining on the surface of the circuit board will flow obliquely into the water storage tank 700.

[0032] In the circuit board drying device provided in the embodiment of the present application, when the circuit board needs to be dried, the circuit board is first placed on the roller conveyor belt 520 of the inclined plate 510 of the humanoid support, and then the roller conveyor belt 520 is started and the circuit board can be moved toward the inside of the drying chamber 200. After the circuit board enters the inside of the drying chamber 200, the drying fan 400 blows air to dry the circuit board. Since the circuit board is placed obliquely on the roller conveyor belt 520 of the inclined plate 510, under the action of the wind force of the drying fan 400, the etching liquid remaining on the surface of the circuit board will flow obliquely into the water storage tank 700, thereby, the drying fan 400 can easily dry the circuit board thoroughly. With the above-mentioned structural design, it takes less time to dry the circuit board, thereby greatly improving the drying efficiency.

[0033] In some embodiments, a water collecting box 800 is further provided on the bottom surface of the transport channel 900, and the water collecting box 800 is connected to the water storage tank 700. In this way, the remaining etching liquid can be recycled and processed again through the water collecting box 800, thereby improving the utilization rate of resources.
