Description

Technical Field

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

[0002] In the electronics manufacturing industry, drying circuit boards is a critical step in the production process. Its purpose is to remove residual substances such as moisture, flux, and cleaning agents from the surface of the circuit boards to ensure their performance and reliability.

[0003] However, existing circuit board drying equipment still has some problems in use. For example, many existing circuit board drying devices use fixed brackets or tray structures, and the dimensions of their support structures are usually fixed, making it impossible to adjust them according to the length or size of the circuit boards. This means that in actual production, different drying equipment or cumbersome adjustments are required for different specifications of circuit boards, which not only reduces production efficiency but also increases production costs. Furthermore, traditional circuit board drying methods often involve horizontal placement. With horizontally placed circuit boards, the bottom or parts in contact with the support are subject to poor hot air circulation, making it difficult for hot air to directly reach these areas. This results in slower drying speeds in these areas and uneven drying. This uneven drying affects the drying effect of the circuit boards and may even lead to deformation or performance degradation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a circuit board suspension drying device. Through a clamping component, the device can be adjusted according to the length or size of the circuit board, making it suitable for clamping circuit boards of different specifications.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A circuit board suspension drying device includes a drying chamber. Fixed plates are fixedly connected to both the left and right sides of the inner wall of the drying chamber. A sliding plate is slidably connected to the inner wall of each fixed plate. A locking assembly is provided inside the sliding plate, and the sliding plate is relatively fixed to the inner wall of the fixed plate via the locking assembly. A rotating column is rotatably connected to the outer wall of the sliding plate, and a clamping plate is fixedly connected to the outer wall of the rotating column. The clamping plate is used to hold the circuit board. A blower is fixedly connected to the left end of the drying chamber, and the blower is used to dry the circuit board held by the two clamping plates in the drying chamber.

[0007] Furthermore, the locking assembly includes a round tube fixedly connected to the inner wall of the skateboard, a compression spring fixedly connected to the inner wall of the round tube, and round buckles fixedly connected to both the front and rear sides of the compression spring. The round buckles are used to lock the skateboard in the fixed plate.

[0008] Furthermore, the inner wall of the fixing plate has several slots on both the front and rear sides, the size of which is adapted to the size of the round buckle, and the inner wall of the fixing plate has a sliding groove for the sliding plate to slide.

[0009] Furthermore, a built-in motor is fixedly connected to the right end of the inner wall of the left-side slide plate. The drive end of the built-in motor passes through the slide plate and is fixedly connected to a rotating column. The built-in motor is used to drive the rotating column to rotate the plate.

[0010] Furthermore, a threaded rod is rotatably connected to the front end of the inner wall of the card plate, and a clamping plate is threadedly connected to the outer wall of the threaded rod. The outer wall of the clamping plate slides inside the card plate.

[0011] Furthermore, the left and right rear sides of the drying oven are fixedly connected with clips, the outer walls of the clips are fitted with buckles, the outer walls of the buckles are fixedly connected with covers, the front left and right sides of the covers are fixedly connected with hinges, and the bottom ends of the hinges are fixedly connected to the front top of the drying oven.

[0015] 2. In this utility model, the rotating column is driven by a built-in motor to rotate, which in turn drives the circuit board fixed by the clamping plate and the clamping plate to rotate, ensuring that each area of ​​the circuit board can be evenly exposed to hot air, eliminating the need for drying and greatly improving the uniformity of drying.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 2-4 This utility model provides an embodiment of a circuit board hanging drying device, including a drying box 1. The rear left and right sides of the drying box 1 are fixedly connected to clips 4. The outer wall of the clips 4 is fitted with buckles, and the outer wall of the buckles is fixedly connected to a cover 3. The front left and right sides of the cover 3 are fixedly connected to hinges 2. The bottom end of the hinges 2 is fixedly connected to the front top of the drying box 1. The front end of the inner wall of the drying box 1 is fixedly connected to an air outlet 11, which is used to discharge the dried air from the drying box 1. The inner left and right sides of the drying box 1 are fixedly connected to fixing plates 6. A slide plate 7 is slidably connected to the inner wall of the plate 6. A locking assembly is provided inside the slide plate 7. The slide plate 7 is relatively fixed to the inner wall of the fixed plate 6 through the locking assembly. The locking assembly includes a round tube 14 fixedly connected to the inner wall of the slide plate 7. A compression spring 15 is fixedly connected to the inner wall of the round tube 14. Round buckles 12 are fixedly connected to both the front and rear sides of the compression spring 15. The round buckles 12 are used to lock the slide plate 7 in the fixed plate 6. Several slots are opened on both the front and rear sides of the inner wall of the fixed plate 6. The size of the slots is adapted to the round buckles 12. A sliding groove 13 is opened on the inner wall of the fixed plate 6. The sliding groove 13 is used to allow the slide plate 7 to slide.

[0025] Specifically, depending on the specific size and length of the circuit board, the operator needs to press the round buckle 12 on the device. During the pressing process, the round buckle 12 will squeeze the spring 15 and disengage from the slot, entering the slide groove 13 in the fixed plate 6 to release the restriction on the slide plate 7, allowing it to move freely. Once the restriction on the slide plate 7 is released, the operator can pull the slide plate 7 to make it slide smoothly in the fixed plate 6. The movement of the slide plate 7 will cause the distance between the two clamping plates 8 to change, thereby adapting to circuit boards of different sizes. When the distance between the two clamping plates 8 is adjusted to the size of the circuit board, the circuit board is inserted into the clamping plate 8, and the operator stops sliding the slide plate 7. Subsequently, the spring 15 will use its elasticity to spring the round buckle 12 back into the corresponding slot, completing the fixation of the slide plate 7. At this time, the left and right sides of the circuit board have been clamped by the clamping plates 8.

[0026] Reference Figure 1 and Figure 5 The outer wall of the slide plate 7 is rotatably connected to a rotating column 9. The inner wall of the left end of the slide plate 7 is fixedly connected to the right end of an internal motor 16. The drive end of the internal motor 16 passes through the slide plate 7 and is fixedly connected to the rotating column 9. The internal motor 16 is used to drive the rotating column 9 to rotate the clamping plate 8. The front end of the inner wall of the clamping plate 8 is rotatably connected to a threaded rod 17. The outer wall of the threaded rod 17 is threadedly connected to a clamping plate 10. The outer wall of the clamping plate 10 slides inside the clamping plate 8. The outer wall of the rotating column 9 is fixedly connected to a clamping plate 8. The clamping plate 8 is used to clamp the circuit board. The left end of the drying chamber 1 is fixedly connected to a blower 5. The blower 5 is used to dry the circuit board clamped by the two clamping plates 8 in the drying chamber 1.

[0027] Specifically, in order to further secure the circuit board, the operator needs to adjust the position of the clamping plate 10 according to the thickness of the circuit board. This is achieved by rotating the threaded rod 17. The rotation of the threaded rod 17 will cause the clamping plate 10 to move back and forth, thereby clamping the front and rear sides of the circuit board. After the circuit board is fully clamped and fixed, the operator can start the built-in motor 16. The built-in motor 16 will drive the rotating column 9 to rotate, which will in turn drive the clamping plate 8 and the circuit board that has been clamped on the clamping plate 8 to rotate together. This rotational movement helps the circuit board to be heated evenly during the drying process.

[0028] Working principle: First, according to the size and length of the circuit board, press the round buckle 12 so that the round buckle 12 squeezes the spring 15 and enters the slide groove 13 in the fixed plate 6 from the slot to release the restriction on the slide plate 7. Then, pull the slide plate 7 to slide in the fixed plate 6. After the circuit board can be inserted between the two clamping plates 8, stop sliding and clamp the circuit board into the two clamping plates 8. The spring 15 rebounds and clamps the round buckle 12 into the corresponding slot to complete the fixation of the slide plate 7 and the clamping of the left and right sides of the circuit board. Then, according to the thickness of the circuit board, rotate the threaded rod 17 so that the threaded rod 17 and the clamping plate 10 clamp the front and rear sides of the circuit board. Then, start the built-in motor 16 so that it drives the clamping plate 8 and the circuit board clamped on the clamping plate 8 to rotate through the rotating column 9. Then, rotate the cover 3 so that it rotates on the drying box 1 through the hinge 2 to close the top of the drying box 1. Then, start the blower 5 so that the blower 5 can deliver hot air to the circuit board. Then, the dried air is discharged from the air outlet 11.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
