Description

Technical Field

[0001] The utility model relates to the technical field of laser processing of electronic displays, in particular to a laser cooling device and laser equipment. Background Art

[0002] The manufacturing process of electronic displays requires laser cutting, laser engraving, and printing on glass substrates, among other processes that utilize laser equipment. During operation, the laser tube generates significant heat. Overheating can affect the normal operation of the laser equipment. Therefore, laser equipment typically requires cooling devices to prevent overheating.

[0003] In the prior art, Figure 1 As shown, conventional cooling devices typically use coolant as a cooling medium to cool the laser device 3'. The coolant is primarily pumped from the liquid cooling tank 1' by a water pump 4' and introduced into the laser device 3' through a circulating liquid cooling pipe 2'. The coolant then flows through the laser tube (not shown) within the laser emitter and is then directed back from the laser device 3' into the liquid cooling tank 1', thereby achieving a circulating cooling effect on the laser tube. However, during the circulating cooling process, the coolant may deteriorate, or the coolant may carry debris and dust from the laser device 3', as well as foreign matter such as scale deposited in the pipe after long-term use, into the water. These tiny foreign matter is difficult to identify with the naked eye. When the foreign matter remaining in the water flows through the laser tube with the coolant, it may damage the laser tube, affecting the normal operation of the laser tube and even posing a safety hazard to the operation.

[0011] In one embodiment, the circulating liquid cooling pipe includes an output pipe and a return pipe, the first filter is arranged on the return pipe, and the foreign object detection component is arranged between the first filter and the liquid cooling water tank, or the foreign object detection component is arranged in the liquid cooling water tank.

[0012] In one embodiment, the laser cooling device further includes a filter box and a temporary storage box, the filter box and the temporary storage box are connected to each other, and the filter box and the temporary storage box are respectively connected to the liquid cooling water tank.

[0013] In one embodiment, the filter assembly further includes a second filter, and the second filter is disposed in the filter box.

[0014] In one embodiment, the laser cooling device further includes a rest box, which is disposed between the filter box and the temporary storage box, and is connected to the filter box and the temporary storage box respectively.

[0015] In one embodiment, the static box is provided with a slag discharge port, and the slag discharge port is arranged at the bottom of the static box.

[0016] In one embodiment, the laser cooling device further includes a liquid level sensor, which is disposed in the liquid cooling water tank. The liquid level sensor is at the same level as the water outlet of the liquid cooling water tank, or the liquid level sensor is at a higher level than the water outlet.

[0017] In one embodiment, the laser cooling device further includes an alarm component, which is connected to the foreign object detection component, and the alarm component includes a warning display light and a stop display light.

[0018] On the other hand, a laser device is also provided, comprising the above-mentioned laser cooling device and a chassis, wherein the top of the chassis is provided with a working platform for placing the product to be processed, and the inside of the chassis is provided with a placement cavity for placing the liquid cooling water tank. The chassis is also provided with a laser bracket, and a laser emitter is installed on the laser bracket. The circulating liquid cooling pipe is arranged in the laser bracket and connects the liquid cooling water tank and the laser emitter.

[0019] Beneficial effects of the utility model:

[0020] The present invention provides a laser cooling device that cools down the laser tube of the laser emitter by connecting a circulating liquid cooling pipe that flows through the laser emitter to the liquid cooling water tank. Specifically, a driving component is used to provide power for the coolant delivery, and the coolant in the liquid cooling water tank is pumped into the laser emitter through the circulating liquid cooling pipe. After the laser emitter is cooled, the coolant is returned to the liquid cooling water tank. A foreign matter detection component is provided to detect the water quality of the coolant in the liquid cooling water tank or the circulating liquid cooling pipe to determine whether the water quality of the coolant is qualified. When unqualified water quality is detected, the coolant in the liquid cooling water tank is replaced to avoid damage to the laser equipment caused by unqualified coolant with foreign matter, or even safety accidents, which is conducive to ensuring operational safety.

[0021] Furthermore, by providing two liquid-cooling water tanks, namely a first water tank and a second water tank, when cooling the laser device, the first driver first draws coolant from the first water tank and delivers it to the laser emitter to cool the laser tube. When the foreign object detection component detects that the water quality in the first water tank and / or the first liquid-cooling pipeline is unqualified, the foreign object detection component sends a signal to the control module, which controls the first driver to stop, i.e., the first water tank stops cooling and performs a coolant replacement. At this time, the control module controls the second driver to start, which draws coolant from the second water tank and delivers it to the laser emitter to cool the laser tube. Thus, the second water tank takes over the supply of coolant to the laser device from the first water tank for cooling. That is, when the first water tank needs to replace the coolant, the second water tank can continue to cool the laser device, allowing the laser device to operate continuously without having to stop for coolant replacement, which is beneficial to improving the efficiency of the overall operation.

[0034] like Figures 2 to 3 As shown, a laser cooling device of this embodiment includes a liquid cooling water tank 1, a drive component 4, a foreign body detection component 5 and a control module (not shown). The liquid cooling water tank 1 is connected to a circulating liquid cooling pipe 2, which flows through the laser emitter 34 (see Figure 4 ) laser tube; the liquid-cooling water tank 1 includes a first water tank 11 and a second water tank 12, and the circulating liquid-cooling pipe 2 includes a first liquid-cooling pipe 2a and a second liquid-cooling pipe 2b respectively connected to the first water tank 11 and the second water tank 12; the driving component 4 is arranged on the circulating liquid-cooling pipe 2 to provide conveying power for the coolant, and the driving component 4 includes a first driving member 41 and a second driving member 42 respectively arranged on the first liquid-cooling pipe 2a and the second liquid-cooling pipe 2b; the foreign matter detection component 5 is arranged in the liquid-cooling water tank 1 and / or on the circulating liquid-cooling pipe 2 to detect the water quality in the liquid-cooling water tank 1 and / or the circulating liquid-cooling pipe 2; the control module is respectively connected to the driving component 4 and the foreign matter detection component 5 to receive the detection information of the foreign matter detection component 5 and drive the driving component 4.

[0035] In this embodiment, the laser tube of the laser emitter 34 is cooled by connecting a circulating liquid cooling pipe 2 that flows through the laser emitter 34 to the liquid cooling water tank 1. Specifically, a driving component 4 is used to provide power for coolant delivery, and the coolant in the liquid cooling water tank 1 is pumped into the laser emitter 34 through the circulating liquid cooling pipe 2. After cooling the laser emitter 34, the coolant is returned to the liquid cooling water tank 1. A foreign matter detection component 5 is provided to detect the water quality of the coolant in the liquid cooling water tank 1 or the circulating liquid cooling pipe 2 to determine whether the water quality of the coolant is qualified. If the water quality is unqualified, the coolant in the liquid cooling water tank 1 is replaced to prevent the unqualified coolant containing foreign matter from damaging the laser equipment 3 or even causing a safety accident, thereby ensuring operational safety.

[0036] Furthermore, by setting up two liquid-cooling water tanks 1, namely the first water tank 11 and the second water tank 12, when performing the cooling operation of the laser equipment 3, the first driving member 41 first extracts the coolant in the first water tank 11 and transports it to the laser emitter 34 to cool the laser tube. When the foreign matter detection component 5 detects that the water quality in the first water tank 11 and / or the first liquid-cooling pipe 2a is unqualified, the foreign matter detection component 5 sends a signal to the control module, and the control module controls the first driving member 41 to stop, that is, the first water tank 11 stops the cooling operation, and the coolant is replaced. At this time, the control module controls the second driving member 42 to start, and the second driving member 42 extracts the coolant in the second water tank 12 and transports it to the laser emitter 34 to cool the laser tube, so that the second water tank 12 replaces the first water tank 11 to supply coolant to the laser equipment 3 for cooling operation, that is, when the first water tank 11 needs to replace the coolant, the second water tank 12 can continue to perform cooling operations, so that the laser equipment 3 can continue to operate without stopping to wait for the coolant to be replaced, which is beneficial to improving the efficiency of the overall operation.

[0037] In actual operation, the driving component 4 can adopt a driving device such as a water pump, which has a simple structure and is easy to use, as long as it can provide power for the transportation of the coolant.

[0038] In one embodiment, the laser cooling device further includes a filter assembly connected to the control module. The filter assembly includes a first filter 61, which is disposed on the first liquid cooling pipe 2a and the second liquid cooling pipe 2b. Specifically, the circulating liquid cooling pipe 2 includes an output pipe 21 and a return pipe 22. The first filter 61 is disposed on the return pipe 22. The first filter 61 filters the coolant in the return pipe 22 before it flows back into the liquid cooling water tank 1, maintaining the overall water quality.

[0039] In this embodiment, if Figure 3As shown, the foreign object detection component 5 can be set between the first filter 61 and the liquid cooling water tank 1, so that the return coolant can be detected after being filtered by the first filter 61 to determine whether it is qualified. Specifically, a three-way valve 23 is also provided on the circulating liquid cooling pipe 2 between the foreign object detection component 5 and the liquid cooling water tank 1, and a drain pipe 13 is also provided on the liquid cooling water tank 1, and a drain valve 131 is provided on the drain pipe 13. During normal operation, the end of the three-way valve 23 connected to the liquid cooling water tank 1 is normally open, and the drain valve 131 is normally closed. When the foreign object detection component 5 detects that the water quality is qualified, it can flow back into the liquid cooling water tank 1 normally. If the detection is unqualified, a signal can be sent to the control module in a timely manner to control the corresponding cooling operation to stop, and the three-way valve 23 is controlled to close the end connected to the liquid cooling water tank 1, open the other end of the three-way valve 23 and the drain valve 131 to discharge the unqualified water quality, and replace the coolant and the first filter 61.

[0040] Of course, in actual operation, Figure 2 As shown, the foreign object detection component 5 can also be directly set in the liquid cooling water tank 1 to directly detect the water quality in the liquid cooling water tank 1, and the water quality of the coolant can also be effectively judged. When the foreign object detection component 5 detects that the water quality in the liquid cooling water tank is unqualified, the coolant supply to the corresponding liquid cooling water tank 1 is stopped, and the drain valve is opened to discharge the coolant from the drain pipe 13, so that the coolant in the liquid cooling water tank 1 and the first filter 61 can be replaced.

[0041] Specifically, the liquid cooling water tank 1 is also provided with a liquid inlet pipe, which is connected to an external cooling liquid supply device. The liquid inlet pipe is provided with a liquid inlet valve. When the cooling liquid is replaced or replenished, the liquid inlet valve is opened and the cooling liquid is supplied to the liquid cooling water tank 1 through the external cooling liquid supply device.

[0042] In one embodiment, the laser cooling device further includes a filter box 71 and a temporary storage box 73, which are interconnected and respectively connected to the liquid cooling water tank 1. The filter box 71 is connected to the liquid cooling water tank 1 via a drain pipe, and the filter box 71 is connected to the three-way valve 23 via a pipe. Specifically, when the foreign matter detection component 5 detects that the water quality is unqualified, the liquid cooling water tank 1 stops supplying coolant to the laser device 3. At this time, the end of the three-way valve 23 connected to the filter box is opened to guide the coolant in the circulating liquid cooling pipe 2 into the filter box 71, and the drain valve 131 is opened to transport the coolant in the liquid cooling water tank 1 to the filter box 71 for filtration. The filter assembly further includes a second filter 62, which is disposed in the filter box 71 and is used to filter the coolant output from the liquid cooling water tank 1. After the coolant is filtered by the second filter 62 in the filter box 71, it is transferred to the temporary storage box 73 for temporary storage, waiting to be transferred to the liquid cooling water tank 1 for use again. Through the filter box 71 and the temporary storage box 73, the coolant can be purified and recycled again, which is beneficial to extending the service life of the coolant and reducing production costs.

[0043] Furthermore, a foreign matter detection component 5 is also provided in the filter box 71 for detecting the coolant after being filtered by the second filter 62 . After the coolant passes the test, the qualified coolant is transported to the temporary storage box 73 .

[0044] Furthermore, the laser cooling device also includes a resting tank 72, which is positioned between the filter tank 71 and the temporary storage tank 73 and is connected to both. Specifically, after the coolant is filtered by the filter tank 71, it is first transferred to the resting tank 72 for settling to prevent the presence of small amounts of foreign matter in the filtered coolant. After settling in the resting tank 72, the supernatant in the resting tank 72 is transferred to the temporary storage tank 73 for temporary storage pending further use.

[0045] Specifically, if Figure 2As shown, the temporary storage tank 73 is provided with a first return pipe 731 and a second return pipe 732 connected to the first water tank 11 and the second water tank 12, respectively. The first return pipe 731 is provided with a first return pump 733 and a second return valve 734, and the second return pipe 732 is provided with a second return pump 735 and a second return valve 736. When the coolant in the temporary storage tank 73 needs to be transported to the first water tank 11, the first return pump 733 and the first return valve 734 are opened to transport the coolant in the temporary storage tank 73 to the first water tank 11 for reuse through the first return pipe 731. Similarly, when the coolant in the temporary storage tank 73 needs to be transported to the second water tank 12, the second return pump 735 and the second return valve 736 are opened to transport the coolant in the temporary storage tank 73 to the second water tank 12 for reuse through the second return pipe 732.

[0046] In one embodiment, the resting box 72 is provided with a slag discharge port 721, which is located at the bottom of the resting box 72. After the coolant has been allowed to rest in the resting box 72 for a certain period of time, the supernatant in the resting box 72 is transferred to the temporary storage box 73. The slag discharge port 721 is then opened to discharge foreign matter and residue from the bottom of the resting box 72, thereby ensuring the cleanliness of the coolant and avoiding the risk of equipment damage caused by reuse of coolant mixed with foreign matter.

[0047] In one embodiment, the laser cooling device further includes a liquid level sensor 8, which is disposed within the liquid cooling water tank 1. The liquid level sensor 8 is positioned at the same level as the water outlet of the liquid cooling water tank 1, or at a level higher than the water outlet. The liquid level sensor 8 monitors the coolant volume within the liquid cooling water tank 1 in real time to prevent coolant evaporation during long-term use, leading to insufficient coolant supply and thus affecting the cooling effect on the laser device 3.

[0048] In one embodiment, the laser cooling device further includes an alarm component connected to the foreign matter detection component 5. The alarm component includes a warning indicator light 91 and a stop indicator light 92. In actual operation, a preset value is set for the foreign matter detection component 5. When the foreign matter concentration detected reaches a first concentration, the foreign matter detection component 5 feeds a signal back to the alarm component, and the warning indicator light 91 of the alarm component illuminates, alerting the operator that the coolant quality is about to exceed the normal operating range, thereby achieving a warning effect. Furthermore, when the foreign matter detection component 5 detects that the foreign matter concentration reaches a second concentration exceeding the normal value, the foreign matter detection component 5 feeds a signal back to the alarm component, and the stop indicator light 92 of the alarm component illuminates, reminding the operator to replace the coolant promptly.

[0049] In this embodiment, if Figure 4As shown, a laser device 3 is also provided, including the above-mentioned laser cooling device, and also including a chassis 31. The top of the chassis 31 is provided with a work platform 32 for placing the product 10 to be processed. The interior of the chassis 31 is provided with a placement cavity 311 for placing the liquid cooling water tank 1. The chassis 31 is also provided with a laser bracket 33, and the laser bracket 33 is mounted on the laser emitter 34. The circulating liquid cooling pipe 2 is provided in the laser bracket 33 and connects the liquid cooling water tank 1 and the laser emitter 34. Specifically, a warning display light 91 and a stop display light 92 are provided on the laser bracket 33 to facilitate intuitive observation by the operator so that the corresponding operation can be made in a timely manner.

[0050] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
