DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] As shown in the atta Figures 1 to 4An electronic material reversible dryer shown in the figure includes a drying box body 1. Both the upper and lower sides of the inner wall of the drying box body 1 are connected with rotating shafts 2 through bearings. The tops of the two groups of rotating shafts 2 are both connected with connecting frames 3. The upper surface of the connecting frame 3 is arranged with sliding grooves 4. The top of the connecting frame 3 is provided with a supporting mesh plate 5. The bottom of the supporting mesh plate 5 is connected with sliding strips 6. The sliding strips 6 are embedded in the sliding grooves 4. The surface of the supporting mesh plate 5 is arranged with partition cavities 7. The edges of the supporting mesh plate 5 are arranged with clamping grooves 8. Guide rods 9 penetrate through both sides of the connecting frame 3. The tops of the guide rods 9 are connected with a limiting mesh plate 10. The limiting mesh plate 10 corresponds to the supporting mesh plate 5. The bottom edges of the limiting mesh plate 10 are arranged with clamping blocks 11. The clamping blocks 11 are embedded in the clamping grooves 8. The top of the limiting mesh plate 10 is provided with a handle 12.

[0023] Among them: The drying box body 1 plays a role in supporting and heat preservation. The rotating shaft 2 can rotate in the drying box body 1 to drive the connecting frame 3 to rotate synchronously. The supporting mesh plate 5 can move horizontally along the sliding groove 4 through the sliding strip 6. At the same time, both the supporting mesh plate 5 and the limiting mesh plate 10 are mesh breathable structures to facilitate drying of electronic materials. When drying is required, the handle 12 can be pulled to raise the limiting mesh plate 10. The raising of the limiting mesh plate 10 drives the clamping block 11 to move out of the clamping groove 8, thus canceling the positioning of the supporting mesh plate 5. By pulling out the supporting mesh plate 5 to the outside of the connecting frame 3, it is convenient to place electronic materials. The electronic materials are respectively placed in the partition cavities 7 in sequence to limit the electronic materials and prevent them from being disordered during the flipping process. After placing, the supporting mesh plate 5 is pushed back to the bottom of the limiting mesh plate 10, and then the limiting mesh plate 10 can be lowered so that the clamping block 11 is embedded in the clamping groove 8 for fixation, facilitating subsequent drying work.

[0024] Embodiment 2

[0025] On the basis of Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, and the details are described below:

[0026] As a preferred embodiment, one end of the guide rod 9 away from the limit mesh plate 10 passes through the connecting frame 3 and is connected with a limit block 13. A threaded groove 131 is provided on the outer wall of the bottom of the guide rod 9. An adjusting nut 14 is provided on the top of the limit block 13. The adjusting nut 14 is threadedly connected with the threaded groove 131. A gasket 15 is provided on the top of the adjusting nut 14. A spring 16 is connected to the top of the gasket 15. Both the gasket 15 and the spring 16 are sleeved on the outer wall of the guide rod 9. One end of the spring 16 away from the gasket 15 abuts against the connecting frame 3. Further, due to the resilience of the spring 16, the limit mesh plate 10 is always in close contact and fixed with the support mesh plate 5 without applying external force. At the same time, when it is necessary to adjust the different clamping degrees between the limit mesh plate 10 and the support mesh plate 5, the adjusting nut 14 can be twisted to perform a lifting movement, thereby adjusting the position of the gasket 15 on the guide rod 9, pressing or relaxing the spring 16, so as to adjust the clamping degree of the limit mesh plate 10 and avoid the situation that the limit mesh plate 10 loosens when encountering heavier electronic materials.

[0027] As a preferred embodiment, a drive box 17 is provided on one outer wall of the drying box body 1. One end of each of the two rotating shafts 2 extends into the drive box 17, and the rotating shafts 2 are connected to the inner wall of the drive box 17 through bearings. Gear 18 is key-connected to the outer walls of the two rotating shafts 2 extending into the drive box 17. The two gears 18 are connected by a transmission belt 19. Further, the drive box 17 plays a role of fixing and driving. The two rotating shafts 2 are synchronously rotated through the connection of the gears 18 and the transmission belt 19.

[0028] As a preferred embodiment, a servo motor 20 is provided on one side of the drive box 17. The output end of the servo motor 20 is connected to one of the top rotating shafts 2. The servo motor 20 drives one of the rotating shafts 2 to rotate. When the rotating shaft 2 rotates, the gear 18 rotates synchronously. The gear 18 rotates and drives the two gears 18 to rotate synchronously through the transmission belt 19, driving the two gears 18 to rotate synchronously and driving the two rotating shafts 2 to rotate synchronously. Further, during the drying process, the servo motor 20 can be driven to drive one of the rotating shafts 2 to rotate. When the rotating shaft 2 rotates, the gear 18 rotates synchronously. The gear 18 rotates and drives the two gears 18 to rotate synchronously through the transmission belt 19, driving the two gears 18 to rotate synchronously and driving the two rotating shafts 2 to rotate synchronously. The rotating shaft 2 rotates to drive the connecting frame 3 to rotate synchronously. The connecting frame 3 rotates to drive the support mesh plate 5 and the limit mesh plate 10 to rotate and turn over, so as to turn over the electronic materials during the drying process, facilitating the all-round and uniform drying work. At the same time, a brake mechanism is provided inside the servo motor 20, which can brake and lock the rotating shaft 2 when not powered on to avoid random rotation.

[0029] As a preferred embodiment, electric heating strips 21 are arranged on the inner wall of the middle part of the drying box body 1, and a temperature sensor 22 is arranged above the inner wall on one side of the drying box body 1; further, the electric heating strips 21 are energized to heat up so as to increase the temperature inside the drying box body 1 for drying the electronic materials, and the temperature inside the box can be detected in real time through the temperature sensor 22 for precise temperature control.

[0030] As a preferred embodiment, a hot air blower 23 is arranged on the outer wall of the drying box body 1 on the side far from the drive box 17. Both ends of the hot air blower 23 are connected with a diversion pipe 24. The bottom end of the diversion pipe 24 penetrates through the drying box body 1 and is connected with an air outlet hood 25. The top end of the diversion pipe 24 is communicated with the outer wall above the drying box body 1 and is connected with a circulating air inlet 26. An activated carbon adsorption box 27 is arranged in the middle of the diversion pipe 24. A heat dissipation end cover 28 is connected to the center of the top end of the drying box body 1, and a control panel 29 is arranged on one side of the top of the drive box 17; further, the hot air blower 23 can draw the heat flow at the top of the drying box body 1 into the diversion pipe 24 through the circulating air inlet 26 and then pump it into the air outlet hood 25 at the bottom of the box body for discharge, thus realizing the function of hot air circulation, improving the uniformity of drying the electronic materials. At the same time, after the heat flow passes through the activated carbon adsorption box 27, the humid water vapor in the air can be adsorbed, thus improving the drying effect. After the drying is completed, the heat dissipation end cover 28 and the box door can be opened for rapid heat dissipation, and the temperature inside the drying box body 1 can be controlled through the control panel 29 and other operations.

[0031] The working process of the present utility model is as follows: When drying is required, first, the handle 12 can be pulled to raise the limit mesh plate 10. The raising of the limit mesh plate 10 drives the block 11 to move out of the card slot 8, thus canceling the positioning of the support mesh plate 5. By pulling out the support mesh plate 5 to the outside of the connecting frame 3, it is convenient to place electronic materials. The electronic materials are sequentially placed in the partition cavity 7 to limit the electronic materials and prevent them from being disordered during the flipping process. After placing, the support mesh plate 5 is pushed back to the bottom of the limit mesh plate 10, and then the limit mesh plate 10 can be lowered so that the block 11 is embedded in the card slot 8 for fixation, facilitating subsequent drying work. Driven by the servo motor 20, the rotating shaft 2 on one side rotates. The rotation of the rotating shaft 2 causes the gear 18 to rotate synchronously. The rotation of the gear 18 drives two groups of gears 18 to rotate synchronously through the transmission belt 19. Driving two groups of gears 18 to rotate synchronously drives two groups of rotating shafts 2 to rotate synchronously. The rotation of the rotating shaft 2 drives the connecting frame 3 to rotate synchronously. The rotation of the connecting frame 3 drives the support mesh plate 5 and the limit mesh plate 10 to flip and rotate, thereby flipping the electronic materials during the drying process to facilitate all-round and uniform drying work. Due to the resilience of the spring 16, the limit mesh plate 10 always fits and fixes with the support mesh plate 5 without applying external force. At the same time, when it is necessary to adjust the different clamping degrees of the limit mesh plate 10 and the support mesh plate 5, the adjusting nut 14 can be twisted to perform a lifting movement, thereby adjusting the position of the gasket 15 on the guide rod 9, pressing or relaxing the spring 16 to adjust the clamping degree of the limit mesh plate 10 to prevent the limit mesh plate 10 from loosening when encountering heavier electronic materials. The electric heating strip 21 is energized to heat up, thereby increasing the temperature inside the drying box 1 to facilitate the drying of electronic materials. The temperature sensor 22 can monitor the temperature inside the box in real time to facilitate precise temperature control. The hot air blower 23 can draw the heat flow at the top of the drying box 1 into the diversion pipe 24 through the circulating air inlet 26 and then pump it into the air outlet hood 25 at the bottom of the box for discharge, thereby realizing the function of hot air circulation and improving the uniformity of drying of electronic materials. At the same time, after the heat flow passes through the activated carbon adsorption box 27, the humid water vapor in the air can be adsorbed, thereby improving the drying effect. After drying, the heat dissipation end cover 28 and the box door can be opened for rapid heat dissipation. The temperature inside the drying box 1 can be controlled through the control panel 29. The above is the working principle of the electronic material reversible dryer.
