Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing technology, and in particular to a drying device for printed circuit board processing. Background Technology

[0002] Drying is a crucial step in the manufacturing process of printed circuit boards (PCBs). Existing PCB drying equipment suffers from several problems during use, such as insufficient stability in clamping the PCBs, which can lead to displacement during drying, affecting both the drying effect and the quality of the PCBs.

[0003] The inventors believe that the following defects often exist: the printed circuit board is affected by external forces during the drying process, causing it to move, shake, or fall, resulting in uneven drying, affecting the drying quality of the coating or circuit on the surface of the printed circuit board, and causing a decrease in the product qualification rate; therefore, a drying device for printed circuit board processing is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where printed circuit boards move or shake during the drying process due to external forces, and to propose a drying device for printed circuit board processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for printed circuit board processing, comprising a dryer body, buttons installed on the surface of the dryer body, a clamping device provided on the surface of the dryer body, the clamping device comprising a shaped frame, the shaped frame being fixedly connected to the surface of the dryer body, two shaped plates being slidably connected inside the shaped frame, the surfaces of the two shaped plates being slidably connected to the dryer body, two single-sided plates being fixedly connected to the upper surface of the shaped plates, an arc-shaped plate being fixedly connected to the upper surface of the shaped plates, a clamping plate being rotatably connected to one side of the arc-shaped plate, one side of the clamping plate being rotatably connected to the single-sided plate, a square plate being fixedly connected to the surface of the shaped plates, a square rod being slidably inserted inside the square plate, the surface of the square rod being slidably connected to the arc-shaped plate, and the surface of the square rod being slidably connected to the clamping plate.

[0006] The effect achieved by the above components is as follows: by setting up a clamping device, the printing plate is clamped, which prevents the printing plate from moving, shaking or falling due to external forces during the drying process, resulting in uneven drying, affecting the drying quality of the coating or lines on the surface of the printing plate, and causing a decrease in the product qualification rate, thus improving the practicality of the device.

[0007] Preferably, a connecting rod is fixedly connected to one side of the irregular plate, and a single-hole plate is fixedly connected to one side of the connecting rod. A threaded rod is inserted into the threaded part of the single-hole plate, and the arc surface of the threaded rod is threadedly connected to the irregular frame.

[0008] The aforementioned components achieve the following effect: they can adjust the position of irregularly shaped plates, accurately move them to the appropriate position according to the differences in the size of the printed circuit board, and ensure that both small and large printed circuit boards can be tightly fitted and stably placed by flexibly adjusting the position of the irregularly shaped plates, thereby enhancing the adaptability to printed circuit boards of different sizes.

[0009] Preferably, a spring is fitted onto the surface of the square rod, and the two ends of the spring are fixedly connected to the square plate and the square rod, respectively.

[0010] The effect achieved by the above components is to improve the stability of the square rod, and to prevent the square rod from being affected by external forces, causing it to slide inside the square plate and thus detach from the square plate.

[0011] Preferably, a baffle plate is fixedly connected to the arc surface of the threaded rod, and the surface of the baffle plate is in contact with the single-hole plate.

[0012] The aforementioned components achieve the following effect: preventing the threaded rod from being pulled out, thus avoiding the situation where workers rotate the threaded rod too many times, causing it to separate from the single-hole plate, requiring secondary installation during use and increasing the workload of the workers.

[0013] Preferably, the surface of the dryer body is provided with a protective device, which includes two fixed plates. Both fixed plates are fixedly connected to the surface of the dryer body. A rotating rod is fixedly connected to one side of the two fixed plates that are close to each other. The protective plate is rotatably connected to the arc surface of the rotating rod. Bolts are threaded into the fixed plates, and a bonding plate is fixedly connected to one end of the bolts.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, the button is protected, preventing workers from accidentally touching the button while performing certain related operations during the drying of the printing plate, which could alter the button's parameters and reduce the drying effect of the printing plate, thus improving the reliability of the device.

[0015] Preferably, torsion springs are fitted on the arc surfaces at both ends of the rotating rod, and the two ends of the torsion springs are fixedly connected to the protective plate and the fixed plate, respectively.

[0016] The aforementioned components achieve the following effect: they automatically open the protective panel and keep it in the open position, facilitating further operations by staff.

[0017] Preferably, an absorbent pad is fixedly connected to one side of the protective plate, and the size of the absorbent pad is adapted to the size of the protective plate.

[0018] The aforementioned components achieve the following effects: they absorb the impact force between the dryer body and the protective plate, avoid noise caused by rigid collisions, and prevent wear and scratches on the surface of the protective plate and the dryer body, thus protecting the integrity of the equipment's appearance.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting a clamping device, the printing plate is clamped, which avoids the printing plate from moving, shaking or falling due to external force during the drying process, resulting in uneven drying, affecting the drying quality of the coating or lines on the surface of the printing plate, and causing a decrease in the product qualification rate, thus improving the practicality of the device.

[0021] 2. In this utility model, by setting a protective device, the effect of protecting the button is achieved, which avoids the situation where the staff may accidentally touch the button when performing certain related operations during the drying of the printing plate, which would change the button parameters and reduce the drying effect of the printing plate, thus improving the reliability of the device.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a drying device for printed circuit board processing, including a dryer body 1. A button 2 is installed on the surface of the dryer body 1, and a clamping device 3 is provided on the surface of the dryer body 1. By setting the clamping device 3, the printed circuit board is clamped, preventing it from moving, shaking, or falling due to external forces during the drying process, which would lead to uneven drying, affect the drying quality of the coating or circuit on the surface of the printed circuit board, and reduce the product qualification rate. This improves the practicality of the device. A protective device 4 is provided on the surface of the dryer body 1, which protects the button 2 and prevents workers from accidentally touching the button 2 during certain operations while drying the printed circuit board, which could change the parameters of the button 2 and reduce the drying effect of the printed circuit board. This improves the reliability of the device.

[0031] The specific configuration and function of its clamping device 3 and protective device 4 will be explained below.

[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment: the clamping device 3 includes a shaped frame 301, which is fixedly connected to the surface of the dryer body 1. Two shaped plates 302 are slidably connected inside the shaped frame 301, and the surfaces of the two shaped plates 302 are slidably connected to the dryer body 1. Two single-sided plates 303 are fixedly connected to the upper surface of the shaped plates 302, and an arc-shaped plate 304 is fixedly connected to the upper surface of the shaped plates 302. A clamping plate 305 is rotatably connected to one side of the arc-shaped plate 304, and one side of the clamping plate 305 is rotatably connected to the single-sided plate 303. A square plate 312 is fixedly connected to the surface of the shaped plates 302, and a square rod 306 is slidably inserted inside the square plate 312. The surface of the square rod 306 is slidably connected to the arc-shaped plate 304, and the surface of the square rod 306 is slidably connected to the arc-shaped plate 304. The clamping plate 305 is slidably connected. A connecting rod 308 is fixedly connected to one side of the irregular plate 302. A single-hole plate 309 is fixedly connected to one side of the connecting rod 308. A threaded rod 310 is threaded into the single-hole plate 309. The arc surface of the threaded rod 310 is threadedly connected to the irregular frame 301. When the operator needs to clamp the printing plate, the operator first rotates the threaded rod 310 within the irregular frame 301 until the arc surface of the threaded rod 310 separates from the irregular frame 301. Then, the operator can push the irregular plate 302 to slide within the irregular frame 301 until the irregular plate 302 moves to a suitable position. The operator can then place the printing plate on the surface of the irregular plate 302. When the printing plate is in contact with the surface of the irregular plate 302, the operator rotates the clamping plate. 305. Until the surface of the clamping plate 305 is in contact with the printing plate, the operator pushes the square rod 306 to slide within the square plate 312 until the square rod 306 is inserted into the clamping plate 305. At this point, the position of the irregularly shaped plate 302 is adjusted. This allows for precise movement of the irregularly shaped plate 302 to the appropriate position based on the size of the printing plate. Whether the printing plate is small or large, the position of the irregularly shaped plate 302 can be flexibly adjusted to achieve a tight fit and stable placement, enhancing adaptability to printing plates of different sizes. A spring 307 is fitted onto the surface of the square rod 306, with both ends of the spring 307 fixedly connected to the square plate 312 and the square rod 306, respectively. When the operator needs to clamp the printing plate, they first pull the square rod 306 within the square plate 312. The square rod 306 slides within the plate 312, at which point the spring 307 is stretched until the surface of the square rod 306 separates from the clamping plate 305. Then, the operator can rotate the clamping plate 305 until its surface is in contact with the printing plate. The operator can then release the square rod 306. The rebound force of the spring 307 causes the square rod 306 to slide within the square plate 312 until it inserts into the clamping plate 305. This improves the stability of the square rod 306, preventing it from sliding within the square plate 312 due to external forces, which could lead to its separation from the plate 312. A blocking plate 311 is fixedly connected to the arc surface of the threaded rod 310.The surface of the baffle plate 311 is in contact with the single-hole plate 309. When the operator needs to adjust the position of the irregular plate 302, the operator first rotates the threaded rod 310 within the single-hole plate 309. The threaded rod 310 moves the baffle plate 311 until its surface is in contact with the single-hole plate 309. At this point, the arc surface of the threaded rod 310 is completely separated from the irregular frame 301, thus preventing the threaded rod 310 from being pulled out. This avoids the situation where the operator rotates the threaded rod 310 too many times, causing it to separate from the single-hole plate 309, requiring a second installation and increasing the operator's workload.

[0033] Reference Figure 6 and Figure 7 As shown, specifically, the protective device 4 includes two fixed plates 41, both of which are fixedly connected to the surface of the dryer body 1. A rotating rod 42 is fixedly connected to one side of the two fixed plates 41 that is close to each other. A protective plate 43 is rotatably connected to the arc surface of the rotating rod 42. A bolt 44 is threaded into the fixed plate 41. A bonding plate 45 is fixedly connected to one end of the bolt 44. Torsion springs 46 are fitted on the arc surfaces at both ends of the rotating rod 42. The two ends of the torsion springs 46 are fixedly connected to the protective plate 43 and the fixed plate 41, respectively. When the operator needs to use the button 2, the operator first rotates the bolt 44 to drive the bonding plate 45 to rotate inside the fixed plate 41 until the surface of the bonding plate 45 separates from the protective plate 43. At this time, the torque of the torsion spring 46 drives the protective plate 43 to rotate on the arc surface of the rotating rod 42 until the protective plate 43 no longer affects the rotation of the rotating rod 42. Using button 2 automatically opens the protective plate 43 and keeps it open for easy operation. An absorbent pad 47 is fixedly connected to one side of the protective plate 43, and the size of the absorbent pad 47 is compatible with the size of the protective plate 43. When the operator needs to use button 2, the operator first releases the limit on the protective plate 43. At this time, the torque of the torsion spring 46 drives the protective plate 43 to rotate on the arc surface of the rotating rod 42. The protective plate 43 drives the absorbent pad 47 to move until the surface of the absorbent pad 47 is in contact with the dryer body 1. This absorbs the collision force between the dryer body 1 and the protective plate 43, avoids noise caused by rigid collision, and prevents wear and scratches on the surface of the protective plate 43 and the dryer body 1, thus protecting the integrity of the equipment's appearance.

[0034] Working principle: When the operator needs to clamp the printing plate, firstly, the operator rotates the threaded rod 310 within the irregular frame 301 until the arc surface of the threaded rod 310 separates from the irregular frame 301. Then, the operator can push the irregular plate 302 to slide within the irregular frame 301 until the irregular plate 302 moves to the appropriate position. The operator can then place the printing plate on the surface of the irregular plate 302, and when the printing plate is in contact with the surface of the irregular plate 302, the operator pulls the square rod 306 to slide within the square plate 312. At this time, the spring 307 is stretched until the surface of the square rod 306 separates from the clamping plate 305. Then, the operator can rotate the clamping plate 305 until its surface is in contact with the printing plate. Finally, the operator can release the square rod 306. The square rod 306 is slid within the square plate 312 by the rebound force of the spring 307 until it is inserted into the clamping plate 305. When the operator needs to adjust the position of the irregular plate 302, the operator first rotates the threaded rod 310 within the single-hole plate 309. The threaded rod 310 moves the blocking plate 311 until the surface of the blocking plate 311 is in contact with the single-hole plate 309. At this point, the arc surface of the threaded rod 310 is completely separated from the irregular frame 301, achieving the effect of clamping the printing plate. This prevents the printing plate from moving, shaking, or falling due to external forces during the drying process, which could lead to uneven drying, affect the drying quality of the coating or lines on the surface of the printing plate, and reduce the product qualification rate. This improves the practicality of the device.

[0035] When the operator needs to use button 2, the operator first rotates bolt 44 to rotate the bonding plate 45 within the fixed plate 41 until the surface of the bonding plate 45 separates from the protective plate 43. At this time, the torque of the torsion spring 46 drives the protective plate 43 to rotate on the arc surface of the rotating rod 42. The protective plate 43 drives the absorption pad 47 to move until the surface of the absorption pad 47 is in contact with the dryer body 1, thus achieving the effect of protecting button 2. This prevents the operator from accidentally touching button 2 while performing certain related operations during the drying of the printed plate, which could alter the parameters of button 2 and reduce the drying effect of the printed plate, thereby improving the reliability of the device.
