Description

Technical Field

[0001] This utility model relates to the field of circuit board drying technology, specifically a circuit board drying device. Background Technology

[0002] PCB circuit boards are important electronic components. They are made of insulating board as the base material, cut to a certain size, and have at least one conductive pattern attached to them. They are used to replace the chassis of the electronic components and realize the interconnection between the electronic components. They are the support of the electronic components and the carrier of the electrical connection between the electronic components. In the production and processing of circuit boards, after the circuit board substrate is produced, it needs to be soaked in water and washed, and then dried.

[0003] A search of the China Patent Network revealed a circuit board drying device disclosed in an existing patent (publication number: CN222143552U). This device, through its movable support device, can dry a large number of circuit boards simultaneously, making it more efficient than traditional circuit board drying devices.

[0004] However, the above technical solution still has certain defects. When the device dries a large number of circuit boards, the heating plates inside the drying device are installed at the top and bottom. During the drying process, the circuit boards located in the middle layer of the support are not heated evenly, which can easily lead to poor drying effect of the circuit boards. In some cases, some areas may not be completely dried, which not only affects the quality and performance of the circuit boards, but may also increase the difficulty and cost of subsequent processing. Therefore, a circuit board drying device is proposed. Utility Model Content

[0005] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, a circuit board drying device is proposed, which can effectively ensure the uniformity of the drying effect, thereby improving the drying efficiency.

Both ends of the shelf are rotatably connected to a U-shaped synchronous belt. Meshing synchronous pulleys are installed at the four corners of the inner sides of the two sets of U-shaped synchronous belts. A base rod is fixed to the center of each synchronous pulley. A servo motor driving the synchronous pulley is installed at one end of each base rod. Placement frames are arrayed between the two sets of U-shaped synchronous belts. A circular shaft is provided between the placement frame and the U-shaped synchronous belt, and several placement slots for placing circuit boards are opened inside the placement frame. The adjustment assembly includes an adjustment plate slidably connected to one side of the inner wall of the placement frame. Two sets of limiting rods slide longitudinally inside the adjustment plate.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] A circuit board drying device, such as Figures 1 to 5 As shown, it includes a drying box body 100, a circulating drying component 200 inside the drying box body 100, and an adjusting component 300 on the circulating drying component 200. The circulating drying assembly 200 includes a shelf 210 that slides into the drying chamber body 100. Both ends of the shelf 210 are rotatably connected to a spiral synchronous belt 220. Each of the four inner corners of the two spiral synchronous belts 220 has a meshing synchronous pulley 230. A base rod 240 is fixed to the center of each synchronous pulley 230. A servo motor 250 for driving the synchronous pulley 230 is mounted at one end of each base rod 240. Placement frames 270 are arrayed between the two spiral synchronous belts 220. A circular shaft 26 is provided between the placement frame 270 and the spiral synchronous belt 220. 0, and the placement frame 270 has several sets of placement slots 271 for placing circuit boards inside. The adjustment component 300 includes an adjustment plate 310 that is slidably connected to one side of the inner wall of the placement frame 270. Two sets of limiting rods 320 slide longitudinally inside the adjustment plate 310. Several sets of limiting slots 321 that cooperate with the limiting rods 320 are arranged in a horizontal array at the bottom of the placement slots 271. The front end of the drying oven body 100 is provided with a door 110. A cooling fan 130 is installed inside the drying oven body 100. Heating plates 120 are installed at both the upper and lower ends of the inner wall of the drying oven body 100.

[0018] The operator places the circuit boards sequentially into the placement slots 271 of the placement frame 270, then pushes the rack 210 into the drying oven body 100, closes the oven door 110, and starts the servo motor 250. The servo motor 250 drives the synchronous pulley 230 to rotate, which in turn moves the circular synchronous belt 220. The movement of the circular synchronous belt 220 causes multiple sets of placement frames 270 to move synchronously, thus causing the circuit boards to circulate within the drying oven body 100. Simultaneously, the heating plate 120 heats the interior of the drying oven body 100. When a placement frame 270 moves below the heating plate 120, it effectively dries the circuit boards inside a set of placement frames 270. The circulating movement of the placement frames 270 ensures that the circuit boards circulate within the drying oven body. The internal drying process is continuous, ensuring uniform drying effect and effectively preventing circuit board deformation due to prolonged drying or residual moisture due to insufficient drying heat. This significantly improves drying efficiency. Simultaneously, by pulling the horizontal plate 330, the operator moves the limiting rod 320, disengaging it from the limiting groove 321. The adjusting plate 310 then clamps and secures the circuit board inside the placement groove 271, preventing it from shaking and falling during movement. Furthermore, the operator can flexibly adjust the internal space of the placement groove 271 according to the size of the circuit board, ensuring its stability during drying and further enhancing the safety and reliability of the drying operation.

[0019] Please refer to this carefully. Figures 1 to 3The bottom of the shelf 210 is equipped with casters 211 to facilitate the movement of the shelf 210.

[0020] By setting universal wheels 211, the shelf 210 can be easily moved inside the drying oven body 100, making it convenient for staff to push or pull the shelf 210 in and out, thus facilitating the placement or removal of circuit boards.

[0021] Please refer to this carefully. Figure 3 and Figure 4 One end of the round shaft 260 is rotatably connected to the placement frame 270, and the other end of the round shaft 260 is fixed to the spiral synchronous belt 220.

[0022] By rotatably connecting one end of the circular shaft 260 to the placement frame 270 and fixing the other end to the spiral synchronous belt 220, it can be ensured that the placement frame 270 moves stably following the rotation of the spiral synchronous belt 220, thereby improving the stability of the circuit board during the drying process.

[0023] Please refer to this carefully. Figure 5 The tops of the two sets of limiting rods 320 pass through the top of the placement frame 270 and are fixedly connected by the setting horizontal plate 330. Multiple sets of protective strips 340 are provided on the inner wall of the placement frame 270 away from the adjustment plate 310. The protective strips 340 are slidably connected to one side of the placement groove 271, and a spring 350 is fixed on one side of the protective strips 340. The other end of the spring 350 is connected to the placement frame 270.

[0024] The protective strip 340 serves to protect the circuit board, while the spring 350 resets the protective strip 340.
