Description

Technical Field

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

[0002] During the etching process of circuit boards, heat treatment is usually required to ensure the uniformity and stability of the etching effect. However, the heated circuit boards need to be air-dried before subsequent use to remove surface moisture and residues. Existing air-drying racks mostly adopt a multi-layer structure design, which can improve drying efficiency while saving space.

[0003] However, this multi-layered structure has certain limitations when stored, mainly because its angle cannot be adjusted, resulting in a large space occupation during storage. This fixed angle design makes it difficult to fold or compress the drying rack when not in use, thus occupying a significant amount of space and causing inconvenience for storage and transportation. Furthermore, the large space occupation also affects the tidiness of the work environment and reduces space utilization. Therefore, how to maintain the advantages of the multi-layered structure while enabling angle adjustment of the drying rack to reduce space occupation during storage has become an urgent problem to be solved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a circuit board air drying device, which solves the problem mentioned in the background art that existing devices occupy a large amount of space when storing circuit boards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board air-drying device, comprising a bracket, a first layer plate, a second layer plate, and a sliding rod. Two brackets are provided, with the first and second layer plates positioned between them. One side of the first and second layer plates are rotatably connected to the inner sides of the two brackets, respectively. A connecting rod is provided on one side of each bracket. The first and second layer plates are connected to each other via the connecting rod, and the connecting rod is rotatably connected to both the first and second layer plates. The topmost first and second layer plates are connected to the bottom ends of two springs, and the top ends of the springs are connected to the top ends of the two brackets. The top end of each bracket has an L-shaped structure. A connecting block is welded to one side of each bracket. The connecting block has a groove inside, and a pin is inserted into the groove. The other end of the pin is inserted into the first and second layer plates.

[0006] Preferably, the bottom ends of the two brackets are T-shaped, and the bottom ends of one bracket are rotatably connected to one end of the connecting rod, while the bottom end of the other bracket is welded to one end of the threaded rod. The other end of the threaded rod is internally threaded to the connecting rod. By rotating the two connecting rods at the bottom of the device, the connecting rod can extend and retract through the thread at one end of the threaded rod, thereby facilitating the adjustment of the length between the connecting rod and the threaded rod.

[0007] Preferably, a sliding rod is welded to one side of the second layer plate, and a slot is formed on one side of the first layer plate. The inner wall of the slot slides in contact with the outer wall of one end of the sliding rod, and the sliding rod can slide outward inside the first layer plate, thereby allowing the width of the device to be adjusted, and thus allowing the device to be adjusted according to different circuit board widths.

[0008] Preferably, multiple sliding rods are provided, and the sliding rods are distributed in a straight line with equal spacing, so that the first layer plate and the second layer plate can maintain a good load-bearing capacity.

[0009] Preferably, one end of the first layer plate and one end of the second layer plate are L-shaped, and both the surface of the first layer plate and the second layer plate are provided with a rubber coating. The L-shaped structure of one end of the first layer plate and one end of the second layer plate helps to prevent the circuit board from slipping off one end.

[0010] This utility model provides a circuit board air drying device. It has the following beneficial effects:

[0011] (1) The circuit board air drying device, when in use, adjusts the first and second layers to a horizontal state, and then fixes the bottom first and second layers with pins. The circuit board is placed on the surface of the first and second layers for drying. When not in use, the pins are pulled outward, and under the pull of the spring, one end of the first and second layers can be lifted upward. Then, under the action of the connecting rod, the lower first and second layers can be tilted. By adjusting the first and second layers to a tilted state, the space occupied is reduced, and the space occupied when the device is stored is reduced.

[0012] (2) The circuit board air drying device can extend and retract through the thread at one end of the threaded rod by rotating the two connecting rods at the bottom of the device, thereby facilitating the adjustment of the length between the connecting rod and the threaded rod. The sliding rod can then slide outward inside the first layer of the board, thereby adjusting the width of the device. This allows the device to be adjusted according to different circuit board widths, thus improving the applicability of the device.

[0013] This solves the problem of existing devices taking up too much space when stored. Attached Figure Description
