The above-mentioned solution solves the problem that when the existing circuit board is placed on the assembly line, only the upper surface of the circuit board can be completely dried during the drying process, and the lower surface is prone to incomplete drying, and the circuit board components are easily damaged, which greatly affects the quality of the circuit board.
[0025] According to this specific embodiment, the drying box 102 is fixedly connected to the frame 101 and is located above the frame 101. The conveyor belt 104 is arranged in the frame 101. The two curtains 105 are symmetrically arranged on both sides of the drying box 102. The fixed rotating module is arranged above the frame 101. When drying the circuit board, the circuit board is transported to the drying box 102 through the conveyor belt 104. The personnel fix the circuit board in the drying box 102 through the fixed rotating module and start the drying lamp 103. The drying lamp 103 dries the circuit board in the drying box 102. At the same time, the fixed rotating module drives the circuit board to rotate so that the circuit board is completely dried.
[0026] The fixing frame 106 is fixedly connected to the frame 101 and is located above the frame 101. The electric forward and reverse screw rod 107 is arranged in the fixing frame 106. The two ball nuts 108 are both sleeved on the outside of the electric forward and reverse screw rod 107 and threadedly matched with the electric forward and reverse screw rod 107. The fixing frame 106 has a through groove 116. The two ball nuts 108 are both slidably connected to the fixing frame 106 and are both located in the through groove 116. The two The movable plates 109 are respectively fixedly connected to the corresponding ball nuts 108, and the two sets of driving members are respectively arranged on the corresponding movable plates 109. The two clamping plates 113 are symmetrically arranged in the drying box 102. The two ends of each connecting shaft 112 are respectively connected to the corresponding clamping plates 113 and the driving members, and both pass through the drying box 102. When drying the circuit board, the circuit board is conveyed to the drying box 102 through the conveyor belt 104, and the personnel place the circuit board in the drying box 102. The electric forward and reverse screw rod 107 on the fixing frame 106 is started between the two clamping plates 113. Since the two ball nuts 108 are threadedly matched with the electric forward and reverse screw rod 107, the through groove 116 guides the ball nuts 108, and the two ball nuts 108 move relatively on the electric forward and reverse screw rod 107. Each ball nut 108 drives the movable plate 109 to move. At the same time, the connecting shaft 112 slides toward the drying box 102 and pushes the clamping plate 113 to clamp and fix the circuit board. Then the drying lamp 103 is started. The drying lamp 103 dries the circuit board in the drying box 102. After one side of the circuit board is dried, the connecting shaft 112 is driven to rotate by starting the driving member. At this time, the circuit board rotates, and then the other side of the circuit board is dried continuously to completely dry the circuit board. In the above manner, the circuit board can be completely dried without incomplete drying, thereby ensuring the quality of the circuit board.
[0027] Secondly, the plurality of limit strips 114 are respectively fixedly connected to the corresponding clamping plates 113 and are respectively located on the outer side walls of the corresponding clamping plates 113.

[0029] In addition, the protective cover 115 is sleeved on the outside of the driving motor 111 , and the driving motor 111 is protected by the protective cover 115 to prevent the driving motor 111 from being exposed.
[0030] When drying the circuit board, the circuit board is conveyed into the drying box 102 through the conveyor belt 104. The personnel place the circuit board between the two clamping plates 113 and start the electric forward and reverse screw rod 107 on the fixing frame 106. Since the two ball nuts 108 are threadedly matched with the electric forward and reverse screw rod 107, the through groove 116 guides the ball nuts 108. The two ball nuts 108 move relative to each other on the electric forward and reverse screw rod 107. Each ball nut 108 drives the movable plate 109 to move. At the same time, the connecting shaft 112 slides toward the drying box 102 and pushes The clamping plate 113 clamps and fixes the circuit board, and the limiting strip 114 on the clamping plate 113 limits the circuit board, and then the drying lamp 103 is started, and the drying lamp 103 dries the circuit board in the drying box 102. After one side of the circuit board is dried, the driving motor 111 on the circuit board is started, and the driving motor 111 drives the connecting shaft 112 to rotate, and the circuit board will rotate at this time, and then continue to dry the other side of the circuit board, so that the circuit board is completely dried. Through the above method, it is achieved that the circuit board can be completely dried, and incomplete drying will no longer occur, thereby ensuring the quality of the circuit board.
