[0005] In view of the above problems, it is urgent to carry out innovative design based on the original cooling mechanism of circuit board processing. Utility Model Content

[0008] The motor is fixedly connected to the inner wall of the vertical rod, and the output end of the motor is fixedly connected with a long pin;

[0021] Compared with the prior art, the beneficial effects of the utility model are: the circuit board processing cooling mechanism adopts a new structural design, and its specific contents are as follows:

[0022] (1) When the circuit board processing cooling mechanism is used, the device is installed as a whole at the required position, and then the circuit board to be drilled is placed on the bottom plate. At this time, the motor is started, and the motor drives the working rod to descend through the long pin and the movable block, and the column and the electric drill head slide inside the working rod through the electric slide rail, so that the device as a whole has the most basic drilling function and is easy to operate;

When the connecting shaft rotates, the limit block prevents the connecting shaft from moving in the horizontal direction, thereby ensuring stability.

[0024] Furthermore, during the rising and falling process of the working rod, the working rod drives the rotating shaft to rotate inside the docking plate through the connecting rod, the tooth block and the gear, and the heat dissipation fan is also in a working state, which plays a cooling role. That is, during the normal drilling process of the device, the function of cooling the circuit board can be completed without the need for additional parts and components, and the economic cost is high;

[0025] (2) In the circuit board processing cooling mechanism, when the movable block rises and the connecting shaft is driven to rotate by the traction rope, the torsion spring is stretched, and then when the motor rotates and the movable block descends, the connecting shaft also rotates under the action of the torsion spring. When the connecting shaft rotates, the traction rope is reeled in for easy use later, and when the fan rotates, it also accelerates the airflow and has a heat dissipation effect;

[0026] Furthermore, the lower surface of the traction rope fits with the upper surface of the transition shaft, and thus the transition shaft can keep the traction rope in a straight state at all times, thereby maximizing the pulling force of the traction rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 1: By setting the motor 3, the electric slide rail 7 and the electric drill 9, the device as a whole has the function of drilling holes in a circuit board, such as Figure 1 and Figure 2 As shown:

[0037] It includes a bottom plate 1 and a motor 3. The upper surface of the bottom plate 1 is fixedly connected with a vertical rod 2, and the vertical rod 2 is symmetrically distributed about the center of the bottom plate 1, and the surface of the vertical rod 2 is concave. The motor 3 is fixedly connected to the inner wall of the vertical rod 2, and the output end of the motor 3 is fixedly connected with a long pin 4.

[0038] A circuit board processing cooling mechanism, further comprising:

[0039] A movable block 5, which is movably arranged inside the vertical rod 2, and a working rod 6 is fixedly connected to the surface of the movable block 5; an electric slide rail 7, which is arranged inside the working rod 6, and a column 8 is fixedly connected to the surface of the electric slide rail 7, and an electric drill bit 9 is rotatably arranged at the end of the column 8;

[0040] A transition shaft 10 is rotatably arranged on the surface of the vertical rod 2, a fixed plate 11 is fixedly connected to the upper surface of the bottom plate 1, and a connecting shaft 12 is rotatably arranged inside the fixed plate 11, and a fan 16 is fixedly connected to the end of the connecting shaft 12, and a baffle 14 is fixedly connected to the end of the connecting shaft 12;

[0041] The docking plate 20 is fixedly connected to the upper surface of the bottom plate 1 , and a rotating shaft 21 is rotatably arranged inside the docking plate 20 , and a heat dissipation fan 23 is fixedly connected to the end of the rotating shaft 21 .

[0042] The long pin 4 is threadedly connected to the movable block 5 , and a traction rope 15 is fixedly connected to the surface of the movable block 5 , and the traction rope 15 is symmetrically distributed about the center of the movable block 5 , and the traction rope 15 corresponds to the transition shaft 10 one by one.

[0043] When in use, the device is installed as a whole at the required position, and then the circuit board to be drilled is placed on the base plate 1. At this time, the motor 3 inside the vertical rod 2 is started, and the motor 3 drives the working rod 6 to descend through the long pin 4 and the movable block 5, while the column 8 and the electric drill bit 9 slide inside the working rod 6 through the electric slide rail 7, so that the device as a whole has the most basic drilling function and is easy to operate.

[0044] Embodiment 2: Different from Embodiment 1, the device has a cooling function by providing a fan 16, such as Figure 2 and Figure 4 As shown:

[0045] The lower surface of the traction rope 15 is in contact with the upper surface of the transition shaft 10 , and the other side of the traction rope 15 is fixedly wound around the surface of the connecting shaft 12 , and the surface of the connecting shaft 12 is fixedly connected to the limiting block 13 .

[0050] A gear 22 corresponding to the gear block 19 is fixedly connected to the surface of the rotating shaft 21 , and a limiting piece 25 is fixedly connected to the surface of the rotating shaft 21 , and the limiting piece 25 is arranged on both sides of the docking plate 20 .

[0051] During the rising and falling process of the working rod 6, the working rod 6 drives the rotating shaft 21 to rotate inside the docking plate 20 through the connecting rod 17, the tooth block 19 and the gear 22 (the limit plate 25 makes the rotation of the rotating shaft 21 more stable), and then the heat dissipation fan 23 is also in a working state, which plays a cooling role. That is, during the normal drilling process of the device, the function of cooling the circuit board can be completed without the need for additional components and high economic cost. At the same time, the through hole 18 facilitates the movement of the connecting rod 17 and the tooth block 19.
