[0027] like Figure 1-2 As shown, the utility model preferably provides a spindle cooling system 100, which includes a water tank 1, a spindle unit 2, a water outlet pipe 3, a water return pipe 4 and a control unit 5. The water tank 1 is provided with a cavity for storing cooling water, and a cooling member 11 is provided in the cavity; the spindle unit 2 includes a spindle 21, and a cooling pipe 22 communicating with the outside is provided inside the spindle 21, and the spindle unit 2 is communicated with the water tank 1 through the cooling pipe 22; one end of the water outlet pipe 3 is connected to the water outlet of the cooling member 11, and the other end is connected to the water inlet of the cooling pipe 22, and a cooling water circulation pump 31 is provided on the water outlet pipe 3; one end of the water return pipe 4 is connected to the water inlet of the cooling member 11, and the other end is connected to the water outlet of the cooling pipe 22; a water temperature sensor 12 is provided inside the water tank 1, a water pressure sensor 32 is provided on the cooling water circulation pump 31, and a temperature sensor 211 is provided inside the spindle unit 2, and the water temperature sensor 12, the water pressure sensor 32 and the temperature sensor 211 are all electrically connected to the control unit 5;

[0028] The control unit 5 is electrically connected to the spindle unit 2 , and the control unit 5 can drive the spindle unit to stop 2 operation.

[0029] Based on the above technical features, 1) through the water temperature sensor 12, the water temperature sensor 12 is installed in the water tank to detect the water temperature in the return pipe 4. When the water temperature of the cooling water in the return pipe 4 is not within the preset range of the water temperature sensor 12, the water temperature sensor 12 in the water tank will be triggered, and the electrical signal will be transmitted to the control unit 5. The control unit 5 will then transmit an electrical signal to the spindle unit. The spindle unit will automatically control the gong machine to stop and alarm after receiving the electrical signal, thereby realizing the first level of overheating protection for the gong machine spindle; 2) through the water pressure sensor 32, the water pressure sensor 32 is set on the cooling water circulation pump 31. When the cooling water circulation pump 31 fails, the cooling water circulation pump 31 When the water pressure is insufficient, the water pressure sensor 32 will be triggered. At this time, the water pressure sensor 32 gives a signal to the control unit 5, and the control unit 5 gives a signal to the spindle unit 2. The spindle unit 2 automatically controls the gong machine to stop and alarm to avoid overheating of the spindle 21, effectively realizing the second anti-overheating protection of the gong machine spindle; 3) Through the temperature sensor 211, the temperature sensor 211 is arranged on the spindle unit 2. When the spindle temperature exceeds the set value of the temperature sensor 211, the temperature sensor 211 will be triggered and transmit the signal to the control unit 5. The control unit 5 controls the gong machine to alarm and stop, effectively realizing the third anti-overheating protection of the gong machine spindle.

[0030] As some embodiments of the utility model, the spindle unit also includes a flow sensor 221, which is arranged at the water inlet of the cooling pipe 22 for detecting the flow. Through the arrangement of the flow sensor 221, when the spindle unit 2 is blocked, the flow sensor 221 arranged on the cooling pipe 22 will be triggered, and the signal will be transmitted to the control unit 5, and the control unit 5 will transmit the signal to the spindle unit 2. At this time, the spindle unit 2 controls the gong machine to alarm and stop, effectively avoiding the overheating of the spindle.

[0031] As some embodiments of the utility model, there are multiple spindle units 2, and multiple spindle units 2 are arranged in parallel between the water outlet pipe 3 and the water return pipe 4. The arrangement of multiple spindle units 2 enables the cooling system 100 to cool multiple spindles 21 at the same time, further ensuring the production efficiency of the gong machine.

[0032] As some embodiments of the utility model, the number of flow sensors 221 and temperature sensors 211 is multiple, and a flow sensor 221 is provided at the water inlet of each cooling tube 22, and a temperature sensor 211 is provided at the water outlet of each cooling tube 22. When the cooling water flows through the cooling tube 22, the cooling water takes away the heat of the spindle 21. Through the setting of the flow sensor 221 and the temperature sensor 211, the temperature of each spindle 21 and the flow of cooling water in each cooling tube 22 can be monitored at all times, so as to realize the cooling system 100 to prevent overheating of multiple spindle units 2 at the same time.

[0033] As some embodiments of the present utility model, the control unit 5 includes a water tank control component 51, which is electrically connected to the water temperature sensor 12 and the water pressure sensor 32. The setting of the water tank control component 51 can directly control the water temperature sensor 12 and the water pressure sensor 32 to control the water temperature and water pressure of the cooling water in the water tank. At the same time, when the water tank control component 51 cannot work normally, the spindle control component 52 can still prevent the spindle 21 from overheating, further improving the protection effect of the system on the spindle of the gong machine.

[0034] As some embodiments of the utility model, the control unit 5 also includes a spindle control component 52, and the spindle control component 52 is electrically connected to the flow sensor 221 and the temperature sensor 211. The spindle control component 52 can obtain the electrical signals transmitted by the flow sensor 221 and the temperature sensor 211, and process the electrical signals, thereby knowing the temperature of the spindle 21 and the flow rate of the cooling water in the cooling pipe 22. When any one of the temperature of the spindle 21 and the flow rate of the cooling water in the cooling pipe 22 does not meet the preset range, the spindle control component 52 controls the gong machine to stop, and the gong machine spindle automatically stops running at this time, effectively preventing the gong machine spindle from overheating.

[0035] As some embodiments of the utility model, the water tank control component 51 is electrically connected to the spindle control component 52, and an actuator for reminding the user is provided on the spindle control component 52. When the spindle control component 52 controls the gong machine to stop, the actuator can automatically alarm, thereby reminding the user that the gong machine spindle cannot operate normally, so that the user can adjust the cooling system 100 in time, so that the gong machine spindle can operate normally, further improving the production efficiency of the gong machine.

[0036] As some embodiments of the utility model, the medium in the water tank 1, the water outlet pipe 3, the water return pipe 4 and the cooling pipe 22 is distilled water. Because distilled water is not easy to have microorganisms after distillation, it is effectively prevented that the medium of the cooling system 100 has pollutants and microorganisms after long-term use, which leads to the blockage of the pipes in the cooling system 100. The use of distilled water can effectively reduce the risk of blockage in the pipes.

[0037] In summary, the utility model embodiment provides a spindle cooling system 100, which has the following beneficial effects: 1) through the water temperature sensor 12, the water temperature sensor 12 is installed in the water tank to detect the water temperature in the return pipe. When the water temperature of the cooling water in the outlet pipe 3 is not within the preset range of the water temperature sensor 12, the water temperature sensor 12 in the water tank will be triggered, and the electrical signal will be transmitted to the control unit 5. The control unit 5 will then transmit an electrical signal to the spindle unit 2. The spindle unit 2 will automatically control the gong machine to stop and alarm after receiving the electrical signal, thereby realizing the first level of overheat protection for the gong machine spindle; 2) through the water pressure sensor 32, the water pressure sensor 32 is arranged on the cooling water circulation pump 31. When the cooling water circulation pump 31 fails, the water pressure sensor 32 will be automatically set to the cooling water circulation pump 31. When the cooling water pressure of the cooling water circulation pump 31 is insufficient, the water pressure sensor 32 will be triggered. At this time, the water pressure sensor 32 gives a signal to the control unit 5, and the control unit 5 transmits the signal to the spindle unit 2. The spindle unit 2 automatically controls the gong machine to stop and alarm, avoiding the overheating of the gong machine spindle, and realizing the second anti-overheating protection of the gong machine spindle; 3) through the temperature sensor 211, the temperature sensor 211 is set on the spindle unit 2. When the temperature of the spindle 21 exceeds the set value of the temperature sensor 211, the temperature sensor 211 will be triggered and transmit the signal to the control unit 5. The control unit 5 makes the gong machine alarm and stop, realizing the third anti-overheating protection of the gong machine spindle. The utility model has multiple gong machine spindle overheating prevention mechanisms, which effectively avoids the overheating of the gong machine spindle, resulting in quality problems of the circuit boards produced by the gong machine.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
