Description

Technical Field

[0001] The invention relates to the technical field of cooling a drilling machine, in particular to a central air-conditioning water cooling system for cooling a circuit board drilling machine. Background Art

[0002] The circuit board drilling machine will generate a lot of heat during operation. This heat mainly comes from the interaction between the drill bit and the circuit board and the heating of the electronic components inside the equipment. In order to reduce this heat, prevent the equipment from overheating and protect key components, it is necessary to use a central air-conditioning water cooling system to cool the circuit board drilling machine to ensure the stable use of the circuit board drilling machine.

[0003] A Chinese patent (application number CN202020765421.4) discloses a central water-cooled air-conditioning system, including a chiller, a cooling tower, an ice water bucket and an air-conditioning unit, wherein the chiller is composed of a plurality of chillers, each of which is equipped with a cooling tower, wherein the chiller is connected to the cooling tower via a first water inlet pipe and a first water outlet pipe, wherein the chiller is connected to the ice water bucket via a second water inlet pipe and a second water outlet pipe, wherein the ice water bucket is connected to the air-conditioning unit via a third water inlet pipe and a third water outlet pipe, wherein the cooling tower is connected to the ice water bucket via a fourth water inlet pipe and a fourth water outlet pipe, wherein a conversion solenoid valve is provided on both the fourth water inlet pipe and the fourth water outlet pipe. When the ambient temperature is lower than a certain value, natural wind is fully utilized to assist in cooling the circulating water to meet the needs of the air-conditioning unit or other equipment that needs cooling, thereby saving energy and protecting the environment.

[0004] Although the above-mentioned central water-cooled air-conditioning system can utilize natural wind to assist in cooling the circulating water, during use, the central air-conditioning water-cooling system can usually only use a simple water-cooling method to cool the circuit board drilling machine. This cannot continuously cool the circuit board drilling machine, resulting in the circuit board drilling machine being unable to quickly dissipate heat and cool down after use, thereby affecting the cooling effect of the central air-conditioning water-cooling system and being inconvenient to use.

[0047] When the present invention is in use, the cold water in the water tank 13 is injected into the water cooling coil 6 along the seventh pipe 22, and then the motor of the electric slide 28 can be used to drive the electric slide 29 to move to the right, so that the drill bit 40 of the circuit board drilling machine moves to the top of the water cooling coil 6, and then the first electric push rod 36 drives the drill bit 40 to move to the inside of the water cooling coil 6. At this time, the water cooling coil 6 can fit and surround the entire drilling machine, so that the cold water in the water cooling coil 6 can cool the heat emitted by the drill bit 40 of the circuit board drilling machine and the internal electronic components, and then the output shaft of the second servo motor 35 drives the fan rotating rod 32 to rotate, and then the driving pulley 34, the driven pulley 33 and the belt can drive another fan rotating rod 32 to rotate, so that the two fan rotating rods 32 can not only blow air to dissipate heat to the water cooling coil 6, but also dissipate heat and cool the entire drilling machine, so that the circuit board drilling machine can be quickly cooled and cooled;

[0048] When the temperature sensor 27 detects that the temperature at the water-cooling coil 6 is high, it will send a signal to the PLC controller 3. At this time, the PLC controller 3 can energize the solenoid valve 8 to move the valve core of the solenoid valve 8, so that the liquid in the water-cooling coil 6 can flow downward, through the second pipe 11 and the first pipe 10 and enter the cooling elbow 9, so that the cooling elbow 9 can cool the heated liquid, and then the cooling elbow 9 can increase the heat dissipation area to better cool the liquid. Then, the second water pump 19 can be used to inject the liquid in the cooling elbow 9 into the cooling cylinder 16 through the sixth pipe 21, and then the first pipe 10 can be used to cool the liquid. The output shaft of a servo motor 25 drives the rotating shaft 23 to rotate continuously, so that the stirring blade 24 at the rotating shaft 23 can stir the liquid used to cool the drilling machine, which is conducive to quickly dissipating the heat of the liquid and making the temperature of the liquid approach the temperature of cold water. Then, the first water pump 14 can be used to send the cold water in the cooling cylinder 16 to the inside of the water tank 13. At this time, since the water tank 13 is higher than the water cooling coil 6, the water tank 13 can automatically flow into the water cooling coil 6, thereby forming a water cooling system, so that the entire circuit board drilling machine can be continuously cooled and cooled, and the circulating cooling of the circuit board drilling machine is realized, and the cooling effect of the central air conditioning water cooling system is improved;

[0049] The first electric push rod 36 drives the U-shaped seat 37 to move downward, and the drill bit 40 moves to the drilling position of the circuit board body 45. Then, the output shaft of the third servo motor 39 drives the drill bit 40 at the rotating seat 38 to rotate so as to drill holes in the circuit board. Then, the entire circuit board body 45 is placed on the top of the processing table 44. Then, the third electric push rod 46 drives the first rubber strip 49 at the first clamping baffle 48 to move and fit and clamp to one end of the circuit board. At the same time, another third electric push rod 46 can drive the second rubber strip 51 at the second clamping baffle 50 to move and fit and clamp to the other end of the circuit board, so as to clamp and fix the circuit board at the same time, thereby ensuring the stability of the circuit board during drilling.
