Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing, and in particular to a PCB board drying rack. Background Technology
[0002] In the manufacturing process of printed circuit boards (PCBs), the cleaning process is one of the key steps to ensure product quality. Its purpose is to remove residual flux, oil, dust, and other impurities from the PCB surface, preventing problems such as short circuits and poor contact during subsequent processing or use. After cleaning, the PCB must be air-dried to ensure complete evaporation of surface moisture before proceeding to the next stage of assembly or testing.
[0003] However, as electronic devices become larger and more integrated, the size of PCB boards is gradually increasing. Simultaneously, to meet the demands of mass production, the number of PCB boards produced per batch has also increased significantly. Traditional drying methods typically involve laying the boards flat or hanging them on simple racks, which requires a significant amount of production space. Especially in small and medium-sized production workshops, the excessive use of limited space by the drying process not only affects the space utilization of the production area but may also lead to inefficient material flow, extended production cycles, and increased operating costs for the company. Utility Model Content
[0004] To reduce the space occupied during the PCB drying process, this utility model provides a PCB drying rack.
[0005] This utility model provides a technical solution that adopts the following approach:
[0006] A PCB drying rack includes a main frame, drying layers, and limiting plates. The drying layers have several layers, and the limiting plates are arranged in several pieces corresponding to the drying layers. The drying layers are evenly distributed in the vertical direction of the main frame. Each drying layer has multiple insertion slots, which are strip-shaped slots extending along the width direction of the main frame. The drying layers are inclined. The limiting plates are located on the lower inclined side of the corresponding drying layer, on the side of the drying layer with the insertion slots, and are perpendicular to the drying layers. The multiple insertion slots are evenly distributed along the length direction of the main frame.
[0007] During drying, insert one side of the PCB board into the insertion slot and push the PCB board so that it comes into contact with the limiting plate. The movement of the PCB board is restricted from both sides, and the inclined insertion slot can reduce the chance of the PCB board falling off the main frame, so that the PCB board is placed stably on the drying layer while maintaining the spacing.
[0008] Preferably, the limiting plate has a limiting groove on the side near the drying layer, the number of limiting grooves corresponds to the number of insertion grooves, and the limiting groove penetrates the limiting plate along the height direction of the limiting plate.
[0009] When the PCB board is drying, the limiting slot of the limiting plate can be used to insert the side of the PCB board to further stabilize the PCB board and prevent it from sliding or tilting during the drying process, which could lead to deformation or damage.
[0010] Preferably, the main frame is slidably connected with a number of top plates, the top plates are parallel to the drying layers, the number of top plates is set to correspond to the number of drying layers, and the top plates are provided with slots corresponding to the insertion slots; the main frame is also provided with a limiting member, the limiting member limiting the distance between the top plates and their corresponding drying layers.
[0011] Adjusting the distance between the top plate and the drying layer allows the distance between the bottom of the slot and the insertion groove to be adjusted so that when the PCB board is placed on the drying layer, both sides of the PCB board can be inserted into the slot and the insertion groove simultaneously. The slot and insertion groove are designed to further restrict and stabilize the PCB board, improve its stability during the drying process, and reduce the possibility of deformation.
[0012] Preferably, the four top corners of the drying layer are fixedly connected to the main frame, and two guide rods are fixed on the drying layer. The two guide rods are respectively located on both sides of the length direction of the drying layer. The guide rods are perpendicular to the drying layer and are slidably connected to sliding sleeves. The two sides of the top plate are respectively fixedly connected to the sliding sleeves on both sides, and the sliding sleeves are threadedly connected to locking bolts.
[0013] By rotating the clamping bolt, the distance between the top plate and the drying layer can be adjusted to ensure that the PCB board is firmly embedded in the slots and plug grooves on both sides, thereby enhancing the drying stability and effectively preventing deformation.
[0014] Preferably, the bottom of the main frame is also provided with rollers.
[0015] It is easy to move as a whole and adapt to different drying environments. At the same time, after drying, the main frame can be directly connected to the PCB board and pushed to the next process, optimizing the PCB board moving process.
[0016] Preferably, the two sides of the main frame are hollowed out.
[0017] The perforated sidewalls allow for ventilation and heat dissipation, improving drying efficiency.
[0018] In summary, this utility model has the following beneficial technical effects:
[0019] During drying, insert one side of the PCB board into the insertion slot and push the PCB board so that it comes into contact with the limiting plate. The movement of the PCB board is restricted from both sides, and the inclined insertion slot can reduce the chance of the PCB board falling off the main frame, so that the PCB board is placed stably on the drying layer while maintaining the spacing.

[0022] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.
[0023] This utility model discloses a PCB board drying rack.
[0024] Reference Figure 1 A PCB board drying rack includes a main frame 1, a drying layer 2, and a limiting plate 3. The drying layer 2 has several layers, and the limiting plate 3 is arranged in several pieces corresponding to the drying layer 2. The drying layers 2 are evenly distributed in the vertical direction of the main frame 1. The drying layer 2 has multiple insertion slots 4, which are strip-shaped slots that extend along the width direction of the main frame 1. The drying layer 2 is inclined. The limiting plate 3 is arranged on one side of the inclined lower end of the corresponding drying layer 2. The limiting plate 3 is located on the side of the drying layer 2 where the insertion slots 4 are located. The limiting plate 3 is arranged perpendicular to the drying layer 2. The multiple insertion slots 4 are evenly distributed along the length direction of the main frame 1.
[0025] During drying, one side of the PCB board is inserted into the insertion slot 4, and the PCB board is pushed so that it abuts against the limiting plate 3. The movement of the PCB board is restricted from both sides. The inclined insertion slot 4 can reduce the possibility of the PCB board falling off the main frame 1. At the same time, it can keep multiple PCB boards stable and maintain the distance between them, reduce the possibility of adjacent PCB boards scratching, and make the PCB boards stable on the drying layer 2 while maintaining the distance.
[0026] Reference Figure 1 In this embodiment, a limiting groove 5 is provided on the side of the limiting plate 3 near the drying layer 2. The number of limiting grooves 5 corresponds to the number of insertion grooves 4. The limiting groove 5 penetrates the limiting plate 3 along the height direction of the limiting plate 3.
[0027] When the PCB board is drying, the limiting groove 5 of the limiting plate 3 can be used to insert the side of the PCB board to further stabilize the PCB board and prevent it from sliding or tilting during the drying process, which could lead to deformation or damage.
[0028] Reference Figure 1 In this embodiment, the main frame 1 is slidably connected with a number of top plates 6, the top plates 6 are parallel to the drying layer 2, the number of top plates 6 is set according to the number of drying layers 2, and the top plates 6 are provided with slots 7 corresponding to the insertion slots 4; the main frame 1 is also provided with a limiting member, which limits the distance between the top plates 6 and their corresponding drying layers 2.
[0029] Adjusting the distance between the top plate 6 and the drying layer 2 allows the distance between the bottom of the slot 7 and the insertion slot 4 to be adjusted so that when the PCB board is placed on the drying layer 2, both sides of the PCB board can be inserted into the slot 7 and the insertion slot 4 at the same time. The design of the slot 7 and the insertion slot 4 helps to further restrict and stabilize the PCB board, improve the stability of the PCB board during the drying process, and reduce the possibility of deformation of the PCB board.
[0030] Reference Figure 1 In this embodiment, the four top corners of the drying layer 2 are fixedly connected to the main frame 1. Two guide rods 8 are fixed on the drying layer 2. The two guide rods 8 are respectively located on both sides of the length direction of the drying layer 2. The guide rods 8 are set perpendicular to the drying layer 2. The guide rods 8 are slidably connected to the sliding sleeves 9. The two sides of the top plate 6 are respectively fixedly connected to the sliding sleeves 9 on both sides. The sliding sleeves 9 are threadedly connected to the locking bolts 10.
[0031] By rotating the clamping bolt 10, the distance between the top plate 6 and the drying layer 2 can be adjusted to ensure that the PCB board is firmly embedded in the slots 7 and the insertion slots 4 on both sides, thereby enhancing the drying stability and effectively preventing deformation.
[0032] Reference Figure 1 In this embodiment, the bottom of the main frame 1 is also provided with rollers 11.
[0033] It is easy to move as a whole and adapt to different drying environments. At the same time, after drying, the main frame 1 can be directly pushed to the next process to connect the PCB board, thus optimizing the PCB board moving process.
[0034] Reference Figure 1 In this embodiment, the two sides of the main frame 1 are hollowed out.
[0035] The perforated sidewalls allow for ventilation and heat dissipation, improving drying efficiency.
