[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: low drying efficiency, long drying time, affecting production efficiency, uneven drying, resulting in insufficient drying of some circuit boards, affecting product quality; therefore, a printed circuit board drying device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low drying efficiency, long drying time, impact on production efficiency, uneven drying, and insufficient drying of some circuit boards, which affects product quality. Therefore, this invention proposes a printed circuit board drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a printed circuit board drying device, comprising a drying chamber, the drying chamber having a rotatably mounted door, two support rods installed in the inner cavity of the drying chamber, a movable plate slidably connected to the arc surfaces of the two support rods, a placement plate slidably connected to the surface of the movable plate, two sliding grooves opened in the inner cavity of the drying chamber, sliding blocks slidably connected to the inner walls of the sliding grooves of the drying chamber, the sliding blocks being fixedly connected to the side walls of the movable plate, two rows of adjustment grooves opened in the inner cavity of the drying chamber, two support plates fixedly connected to the lower surface of the movable plate, a sliding rod slidably inserted in the support plate, a pull plate fixedly connected to one end of the sliding rod, and the arc surface of the sliding rod slidably connected to the adjustment groove of the drying chamber.

[0006] The aforementioned components achieve the following effect: they enable height adjustment of the movable plate, facilitating the drying of printed circuit boards. This avoids the situation where the height of the plate inside the drying chamber is relatively fixed, requiring power adjustment of the drying chamber to quickly dry the printed circuit boards, which can easily damage the circuit boards during rapid drying and affect their normal use. This improves the practicality of the device.

[0007] Preferably, the arc surface of the sliding rod is fitted with a spring, and the two ends of the spring are fixedly connected to the support plate and the pull plate, respectively.

[0008] The effect achieved by the above components is that, under the action of the spring, the stability of the sliding rod in the drying oven adjustment slot is improved, and the sliding rod is prevented from falling out of the drying oven adjustment slot.

[0009] Preferably, a limiting rod is slidably inserted into the support plate, and a limiting groove is formed on the arc surface of the sliding rod, the size of the limiting rod being adapted to the size of the limiting groove of the sliding rod.

[0010] The effect achieved by the above components is that by setting a limiting rod, the sliding rod after stretching is limited, which makes it easier for the staff to adjust the height of the movable plate and improves the practicality of the device.

[0011] Preferably, a damper is fixedly connected to the inner surface of the drying box slide, and a buffer plate is fixedly connected to one end of the damper.

[0012] The effect achieved by the above components is that, by setting damping, the device can buffer against accidental slippage, thereby improving its practicality.

[0013] Preferably, a protective pad is fixedly connected to the surface of the buffer plate, and the protective pad is made of silicone.

[0014] The effect achieved by the above components is that, through the combination of protective pads and damping, the movable plate is cushioned, preventing the movable plate from causing the placement plate to fall and shake when it falls, thus avoiding collisions between the printed circuit boards on the placement plate and the movable plate, thereby improving the practicality of the device.

[0015] Preferably, a handle is fixedly connected to one side of the placement plate, and the surface of the handle is provided with anti-slip protrusions.

[0016] The effect achieved by the above-mentioned components is that by setting handles, it is easier for workers to remove the placement plate from the movable plate, thus improving the practicality of the device.

[0017] Preferably, an observation window is provided on the surface of the door, and quartz glass is installed inside the observation window.

[0018] The effect achieved by the above components is that the observation window makes it easier for staff to observe the drying process of the printed circuit board, thus improving the practicality of the device.

[0019] This invention achieves the effect of adjusting the height of the movable plate, which facilitates the drying of printed circuit boards. It avoids the situation where the height of the plate inside the drying oven is relatively fixed, requiring the drying oven to adjust its power to quickly dry the printed circuit boards. This avoids the possibility of damage to the circuit boards during the rapid drying process, affecting their normal use, and improves the practicality of the device. Attached Figure Description

[0025] Reference Figure 1-4As shown, this utility model provides a technical solution: a printed circuit board drying device, including a drying chamber 1, a door 2 rotatably installed in the drying chamber 1, two support rods 3 installed in the inner cavity of the drying chamber 1, a movable plate 4 slidably connected to the arc surfaces of the two support rods 3, a placement plate 16 slidably connected to the surface of the movable plate 4, two sliding grooves opened in the inner cavity of the drying chamber 1, sliding blocks 5 slidably connected to the inner walls of the sliding grooves of the drying chamber 1, the sliding blocks 5 being fixedly connected to the side walls of the movable plate 4, two rows of adjustment grooves opened in the inner cavity of the drying chamber 1, two support plates 6 fixedly connected to the lower surface of the movable plate 4, a sliding rod 7 slidably inserted in the support plate 6, a pull plate 8 fixedly connected to one end of the sliding rod 7, and the arc surface of the sliding rod 7 being slidably connected to the adjustment groove of the drying chamber 1. The height of the movable plate 4 is adjustable, facilitating the drying of the printed circuit board. This avoids the situation where the height of the plate 16 inside the drying chamber 1 is relatively fixed, requiring the drying chamber 1 to adjust its power to quickly dry the printed circuit board, which could easily damage the circuit board during rapid drying and affect its normal use. This improves the practicality of the device. A spring 9 is fitted onto the arc surface of the sliding rod 7, and the two ends of the spring 9 are fixedly connected to the support plate 6 and the pull plate 8, respectively. Under the force of the spring 9, the stability of the sliding rod 7 in the adjustment groove of the drying chamber 1 is improved, preventing the sliding rod 7 from falling out of the adjustment groove of the drying chamber 1. A limiting rod 10 is slidably inserted in the support plate 6, and a limiting groove is opened on the arc surface of the sliding rod 7. The size of the limiting rod 10 is adapted to the size of the limiting groove of the sliding rod 7. By setting the limiting rod 10, the stretched sliding rod 7 is limited, making it convenient for the operator to adjust the height of the movable plate 4, thus improving the practicality of the device. A damper 11 is fixedly connected to the inner surface of the sliding groove of the drying chamber 1, and a buffer plate 12 is fixedly connected to one end of the damper 11. By incorporating damping 11, the device effectively cushions accidental slippage, enhancing its practicality. A protective pad 13, made of silicone, is fixedly attached to the surface of the buffer plate 12. The combination of the protective pad 13 and damping 11 effectively cushions the movable plate 4, preventing it from causing the placement plate 16 to fall and vibrate, thus avoiding collisions with the printed circuit boards on the placement plate 16. A handle 14 is fixedly attached to one side of the placement plate 16, with anti-slip protrusions on its surface. The handle 14 facilitates the removal of the placement plate 16 from the movable plate 4, further enhancing the device's practicality. An observation window 15, containing quartz glass, is provided on the surface of the door 2. This window allows workers to easily observe the drying process of the printed circuit boards, further improving the device's usability.

[0026] Working principle: When the operator needs to dry the printed circuit board, they open the door 2, pull the handle 14 to take out the placement plate 16, and then place the printed circuit board on the placement plate 16. When the operator needs to dry it quickly, they need to adjust the position of the movable plate 4. Pulling the pull plate 8 causes the sliding rod 7 to slide within the support plate 6. The sliding rod 7 slides out of the adjustment groove in the drying chamber 1, and the spring 9 is in a stretched state. At this time, it pushes the limiting rod 10 to slide within the support plate 6 until the limiting rod 10 slides into the limiting groove of the sliding rod 7, thus achieving the desired drying effect after stretching. The sliding rod 7 is limited, pushing the movable plate 4 to slide on the arc surface of the support rod 3. The movable plate 4 drives the sliding block 5 to slide in the groove of the drying box 1 until the movable plate 4 is adjusted to the required height. Then, the limit rod 10 is pulled to release the limit rod 10 from the limit of the sliding rod 7. Under the action of the spring 9, the sliding rod 7 automatically springs into the adjustment groove of the drying box 1. After that, the staff places the placement plate 16 on the movable plate 4, closes the box door 2, and opens the drying box 1 to dry the printed circuit board. The staff can observe the drying situation inside the drying box 1 through the observation window 15.
