[0021] 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.

[0022] Please see Figures 1 to 4 The printed circuit board baking device in this embodiment includes a box 1 and a placement frame 2. A sliding component is provided on the placement frame 2, and a rotating heating component is provided on the box 1.

[0023] The sliding assembly includes a placement plate 3 that engages with the inner wall of the placement frame 2. Two connecting plates 4 are fixedly installed on the bottom of the placement plate 3. Bushings 5 ​​are rotatably installed on opposite sides of the two connecting plates 4. Rotating rods 6 are rotatably installed on opposite sides of the two bushings 5.

[0024] The outer side of the rotating rod 6 is threaded with a movable block 7. Both ends of the rotating rod 6 are provided with opposite threaded grooves. The movable block 7 is provided with a threaded hole inside. The movable block 7 is threadedly connected to the rotating rod 6 through the threaded hole. When the rotating rod 6 rotates, it drives the movable block 7 to move in the opposite or opposite direction.

[0025] The top of each of the two movable blocks 7 is fixedly equipped with an L-shaped connecting rod 8, and a snap-fit ​​block 9 is fixedly installed on the opposite side of each of the two L-shaped connecting rods 8. A through hole is provided at the bottom of the placement plate 3, and the L-shaped connecting rod 8 extends into the interior of the placement plate 3 through the through hole. A placement groove for placing the snap-fit ​​block 9 is provided inside the placement plate 3. When the movable block 7 moves, the snap-fit ​​block 9 moves synchronously through the L-shaped connecting rod 8.

[0026] The inner walls of the placement frame 2 are provided with snap-fit ​​grooves on both sides. The snap-fit ​​block 9 snaps into the placement frame 2 through the snap-fit ​​grooves, which makes it easy to adjust and place the placement plate 3 to meet the usage requirements.

[0027] Two limiting plates 10 are slidably mounted on the top of the placement plate 3. The top of the placement plate 3 is provided with a moving groove to facilitate adjustment of the distance between the two limiting plates 10. Several sliding grooves are provided on the opposite side of the two limiting plates 10 to facilitate clamping of the printed circuit board.

[0028] It should be noted that this printed circuit board baking equipment is equipped with a sliding component, which allows for easy adjustment of the spacing between each placement plate 3 according to the size and model of the printed circuit board to be baked. This enables the printed circuit board to be placed vertically for drying, improving the drying effect and quality of the printed circuit board and increasing the flexibility of the equipment.

[0029] Specifically, in use, the printed circuit board baking equipment involves manually rotating the rotating rod 6 to move two moving blocks 7 in opposite directions. Through the L-shaped connecting rod 8, two locking blocks 9 move synchronously, allowing the locking blocks 9 to be stored inside the placement plate 3. Depending on the size of the printed circuit board, the position of the placement plate 3 is then adjusted so that the printed circuit board can be placed vertically for drying. At the same time, the distance between the two limiting plates 10 is adjusted to better clamp the printed circuit board, allowing for better drying.

[0030] The rotating heating assembly includes a drive motor 11 fixedly installed on the top of the housing 1. The output end of the drive motor 11 is fixedly installed with a mounting rod 12 fixedly connected to the top of the placement frame 2. An extension hole is provided on the top of the housing 1. The output end of the drive motor 11 is fixedly connected to the mounting rod 12 through the extension hole. When the drive motor 11 is started, the mounting rod 12 is driven to rotate, thereby driving the placement frame 2 to rotate synchronously.

[0031] A hot air blower 13 is fixedly installed on the top of the housing 1. An air duct 14 is fixedly installed at the output end of the hot air blower 13. An opening is provided on the top of the housing 1. The air duct 14 extends into the interior of the housing 1 through the opening. A number of nozzles are fixedly installed on one side of the air duct 14. A door is hinged to the front of the housing 1. An installation box 15 is fixedly installed on the top of the housing 1. The drive motor 11 is located inside the installation box 15.

[0032] It should be noted that this printed circuit board baking equipment, by installing a rotating heating component, enables the printed circuit boards placed and clamped to rotate and dry evenly, thereby improving the drying quality of the printed circuit boards.

[0033] Specifically, in this printed circuit board baking equipment, after the printed circuit board is clamped and placed, the hot air blower 13 is started to transmit hot air to the inside of the chamber 1 through the air duct 14 to dry the printed circuit board. At the same time, the drive motor 11 is started, which drives the placement frame 2 to rotate through the mounting rod 12, so that the printed circuit board is rotated and dried, thereby improving the drying quality of the printed circuit board.

[0034] The working principle of the above embodiments is as follows:

[0035] (1) When using the printed circuit board baking equipment, manually rotate the rotating rod 6 to drive the two moving blocks 7 to move in opposite directions. Through the L-shaped connecting rod 8, drive the two locking blocks 9 to move synchronously, so that the locking blocks 9 are stored inside the placement plate 3. According to the size of the printed circuit board, adjust the position of the placement plate 3 so that the printed circuit board can be placed vertically for drying. At the same time, adjust the distance between the two limiting plates 10 to better clamp the printed circuit board and make the printed circuit board better dried.

[0036] (2) After the printed circuit board is clamped and placed, the hot air blower 13 is started and the hot air is transmitted to the inside of the box 1 through the air duct 14 to dry the printed circuit board. At the same time, the drive motor 11 is started and the placement frame 2 is rotated through the mounting rod 12, so that the printed circuit board is rotated and dried, thereby improving the drying quality of the printed circuit board.
