[0021] Beneficial effects of the present invention:

[0022] The present invention provides a baking rack for circuit board production, which has a driving assembly and a supporting assembly. When a staff member inserts all the boards into the slots and then turns the handle, the handle drives the first rotating column to rotate. During the rotation of the first rotating column, the first gear plate can be driven to rotate. Through the mutual meshing of the first gear plate, the second gear plate and the third gear plate, the second gear plate and the third gear plate can be made to perform circular motion. When the third gear plate rotates, a group of second threaded screw rods can be driven to rotate. At the same time, the second threaded screw rod can drive the second transmission wheel and the third transmission wheel fixed on the top thereof to rotate together. When the second transmission wheel and the third transmission wheel rotate, the third transmission belt and the second transmission belt rotate together, thereby driving the fourth rotating column to rotate. When the fourth rotating column rotates, the fifth gear plate can be driven to rotate. The mutual engagement between the four gear plates can drive another group of second threaded screws to rotate, thereby realizing the four groups of second threaded screws on the front and rear sides of the drying rack to rotate in opposite directions in pairs. During the rotation of the second threaded screws, the second threaded sleeve threadedly connected to its outer wall can drive the connecting plate and the top block to move vertically. At this time, the second threaded screw located in front of the baking rack and rotating forward can make the top block move upward, while the second threaded screw located behind the baking rack rotates in the opposite direction to make the top block move downward. When the top blocks at the bottom of the plate body that support the plate body rise and fall, the plate body can be tilted and slid toward the rear of the baking machine. At the same time, the top blocks moving in opposite directions up and down can clamp and fix the plate body, further ensuring the stability of the plate body after installation, and can effectively prevent the plate body from slipping from the front of the baking rack and causing damage, thereby ensuring the quality of the plate body after drying.

[0023] The present invention provides a baking rack for circuit board production. By means of the provided blocking assembly, when the drying is completed, the staff moves the board out of the baking equipment to unload the board, and the staff rotates the handle in the opposite direction. At this time, the top block at the front of the baking rack moves downward, and the top block at the rear moves upward, so that the board slides toward the front of the baking rack, thereby facilitating the staff to quickly unload the board. When the front and rear top blocks descend and rise, the third rotating column drives the first transmission wheel to rotate. The first transmission wheel and the first transmission belt cooperate to drive the second rotating column to rotate. During the rotation of the second rotating column, the first bevel gear can be driven to rotate. When the first bevel gear rotates, the second bevel gear meshing with it can be driven to rotate together. The rotation can drive the first threaded screw to rotate. When the first threaded screw rotates, the first threaded sleeve threadedly connected to its outer wall can drive the blocking assembly to move horizontally. The baffle in the blocking assembly can block and limit the plate body of each group to prevent the plate body from sliding out and falling directly from one side of the baking rack when it is not taken out manually. At the same time, one side of the baffle is fixedly connected to the connecting rod through the first spring. Therefore, when the staff needs to take the plate body, they only need to lightly push the baffle to achieve fast unloading, which meets people's usage needs. At the same time, the entire baking rack only requires the staff to simply turn the handle to achieve the tight positioning of the plate body during transportation and baking and the tilting and fast unloading during unloading, which improves the baking efficiency of the plate body and meets people's usage needs.

During the rotation of the first rotating column 13, the first gear plate 24 can be driven to rotate. Through the mutual engagement between the first gear plate 24, the second gear plate 26 and the third gear plate 27, the second gear plate 26 and the third gear plate 27 can be made to perform circular motion.

During the rotation of the second threaded screw rods 29, the second threaded sleeve 58 threadedly connected to the outer wall thereof can drive the connecting plate 60 and the top block 57 to move vertically. At this time, the first threaded screw rod 29 located in front of the baking rack and rotating forwardly can be driven to rotate in opposite directions in pairs. The second threaded screw 29 can make the top block 57 move upward, and the second threaded screw 29 located behind the baking rack rotates in the opposite direction to make the top block 57 move downward. When the top block 57 supporting the bottom of the plate 5 rises and falls, the plate 5 can slide obliquely toward the rear of the baking machine. At the same time, the top block 57 moving in the opposite directions can clamp and fix the plate 5, further ensuring the stability of the plate 5 after installation, and effectively preventing the plate 5 from sliding from the front of the baking rack and causing damage, thereby ensuring the quality of the plate 5 after drying.

[0050] When the drying is completed, the staff will remove it from the baking equipment to unload the plate body 5, and the staff will rotate the handle 9 in the opposite direction. At this time, the top block 57 at the front of the baking rack moves downward, and the top block 57 at the rear moves upward, so that the plate body 5 slides to the front of the baking rack, thereby facilitating the staff to quickly unload the plate body 5. When the top blocks 57 at the front and rear of the baking rack descend and rise, the third rotating column 30 will drive the first transmission wheel 31 to rotate, and the first transmission wheel 31 and the first transmission belt 33 can cooperate to drive the second rotating column 16 to rotate. During the rotation of the second rotating column 16, the first bevel gear 15 can be driven to rotate. When the first bevel gear 15 rotates, it can drive the meshing second bevel gear 17 to rotate together. The rotation of the second bevel gear 17 can drive the first When the threaded screw 18 rotates, the first threaded sleeve 20 threadedly connected to its outer wall can drive the blocking assembly to move horizontally. The baffle plate 36 in the blocking assembly can block and limit the plate body 5 of each group to prevent the plate body 5 from sliding out and falling from one side of the baking rack when it is not taken out manually. At the same time, one side of the baffle plate 36 is fixedly connected to the connecting rod 34 through the first spring 37. Therefore, when the staff needs to take the plate body 5, they only need to lightly push the baffle plate 36 to achieve fast unloading, which meets people's usage needs. At the same time, the entire baking rack only requires the staff to simply turn the handle 7 to achieve the tight positioning of the plate body 5 during transportation and baking and the tilting and fast unloading during unloading, which improves the baking efficiency of the plate body 5 and meets people's usage needs.
