Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a water treatment device for welding equipment and a welding system. Background Art

[0002] Laser welding equipment requires water cooling during the welding process. Usually, the process cooling water system is used to supply cooling water to the chiller. The chiller treats the cooling water from the process cooling water system before cooling the laser welding equipment. Since the chiller is composed of a compressor, condenser, expansion valve, etc., the structure of the chiller is complex and the procurement cost is high. Utility Model Content

[0003] In view of the above problems, the present application provides a water treatment device for welding equipment, which replaces the chiller with a simple pipeline structure, thereby reducing the structural complexity of the water treatment device for welding equipment and reducing costs.

[0004] In a first aspect, the present application provides a water treatment device for welding equipment, comprising:

[0005] a water supply pipeline having a water supply port and a water outlet, wherein the water supply port is configured to admit cooling water, and the water outlet is used to supply water to the welding equipment;

[0006] The filter assembly is arranged in the water supply pipeline and is used to filter water impurities in the water supply pipeline;

[0007] The water supply parameter detection component is arranged in the water supply pipeline and is located downstream of the filter component. The water supply parameter detection component is used to detect the water supply parameters in the water supply pipeline.

[0008] Impurities in the water are filtered out by the filtration assembly, and the water supply parameter detection component detects the water supply parameters, ensuring that the water supplied to the welding equipment is supplied at the preset water supply parameters to cool the welding equipment. By replacing the chiller with a water treatment device, cold water from the process cooling water system is introduced into the water supply port to cool the welding equipment. Compared to the structure of a chiller, this simplifies the structure of the water treatment device, thereby reducing the cost of the water cooling device for laser welding equipment.

[0009] In some embodiments, the filter assembly includes a first filter and a second filter, the first filter being positioned upstream of the second filter.

[0010] The provision of the first filter and the second filter can improve the filtering effect of the water in the water supply pipeline to meet the water quality requirements of the laser welding equipment (the water has large impurities, which will affect the service life of the laser welding equipment and the welding quality); at the same time, compared with the structure using only one filter, the maintenance cycle of the filter component can be extended.

[0011] In some embodiments, there are multiple second filters, which are arranged in parallel in the water supply pipeline to form a second filter group, and the first filter is located upstream of the second filter group.

[0012] As a result, the water quality in the water supply pipeline can be further improved, and the maintenance period of the filter assembly can be further shortened.

[0013] In some embodiments, the water supply parameter detection component includes a flow sensor, which is arranged downstream of the filter assembly of the water supply pipeline. The flow sensor is used to detect the water flow in the water supply pipeline.

[0014] The water treatment device needs to supply a predetermined flow of water to the laser welding equipment to ensure the cooling effect of the laser welding equipment. The flow sensor can detect the water flow of the water supply pipeline in real time to ensure that the water supply pipeline can supply the laser welding equipment with the predetermined flow of water.

[0015] In some embodiments, the water supply parameter detection component includes a flow alarm switch, which is arranged downstream of the filter component of the water supply pipeline. The flow alarm switch is used to issue an alarm prompt when the output flow is not within a preset flow range.

[0016] When the incoming flow rate is not within the preset flow rate range, the flow alarm switch will sound an alarm prompt and adjust the water flow in the water supply pipeline in time, thereby reducing the probability of damage to the laser welding equipment due to too small a flow rate or welding defects due to too large a flow rate.

[0017] In some embodiments, the water supply parameter detection component includes a temperature sensor, which is disposed downstream of the filter assembly in the water supply pipeline. The temperature sensor is used to detect the water temperature in the water supply pipeline.

[0018] Temperature sensors can provide early warning of abnormal water temperature conditions, helping to promptly detect water supply pipeline faults. They also reduce the probability of damage to laser welding equipment or welding defects during the welding process due to excessively high water temperatures.

[0019] In some embodiments, the water supply parameter detection component includes a pressure sensor, which is disposed downstream of the filter assembly in the water supply pipeline. The pressure sensor is used to detect the water pressure in the water supply pipeline.

[0020] Setting a pressure sensor in the water supply pipeline can detect the water pressure in real time to ensure that stable water pressure is provided to the laser welding equipment. When the pressure fluctuates, it can be adjusted in time to prevent the water pressure from being too low and causing insufficient cooling or the water pressure from being too high and causing damage to the equipment.

[0021] In some embodiments, the water treatment device of the welding equipment further includes a shell having an accommodation space formed therein, wherein part of the water supply pipeline, at least part of the filter assembly and at least part of the water supply parameter detection component are all located in the accommodation space.

[0022] The housing's internal containment space integrates at least a portion of the water supply piping, at least a portion of the filtration assembly, and at least a portion of the water supply parameter detection components, providing a unified installation and protective environment. This reduces damage to these critical components from external environmental factors, such as dust and physical impact. Furthermore, the water supply piping, filtration assembly, and water supply parameter detection components are all located within the same containment space, making maintenance and inspection more convenient. Maintenance personnel can inspect, repair, and replace each component in a relatively centralized area, improving work efficiency.

[0023] In some embodiments, at least one side wall of the housing is a transparent wall. The provision of the transparent wall allows maintenance personnel to promptly check the operating status of the water supply parameter detection component, thereby facilitating the location and regular maintenance of the water supply parameter detection component.

[0024] In some embodiments, a water receiving tray is provided inside the housing and is located below the filter assembly for receiving water discharged from the filter assembly.

[0025] The setting of the water tray effectively receives the water discharged from the filter assembly, reducing the probability of water dripping directly onto the ground or other equipment, thereby reducing the probability of the ground being slippery and the equipment being damp due to water leakage, reducing potential safety hazards and equipment damage risks.

[0026] In some embodiments, the water treatment device further includes a first valve, which is disposed upstream of the filter assembly and is used to open or close the water supply pipeline.

[0027] The first valve can conveniently open or close the water supply line, achieving precise control over the water flow. For example, during equipment maintenance or overhaul, the valve can be closed to stop the water supply, ensuring the safety of operators and the smooth progress of work. For example, when replacing the filter component, closing the first valve can prevent water from continuing to flow through, avoiding water leakage and interference with maintenance work. When an emergency occurs in the water supply line, such as a leak or rupture, the first valve can be quickly closed to prevent further water leakage, reducing losses and dangers. By properly controlling the opening of the first valve, the water supply pressure in the water supply line can be adjusted to a certain extent to meet the needs of different working conditions.

[0028] In a second aspect, the present application provides a welding system, comprising:

[0029] Welding equipment with a water inlet and a water outlet;

[0030] In the water treatment device of the welding equipment of the first aspect, the water inlet is communicated with the water outlet.

[0031] Since the welding system includes all the technical features of the water treatment device of the welding equipment of the first aspect, the effects are the same as those described above and will not be described in detail here.

[0032] In some embodiments, the welding equipment is further provided with a drain port, and the welding system further comprises:

[0033] The cooling water system is provided with a cooling water outlet and a circulating water inlet. The cooling water outlet is connected to the water supply port, and the circulating water inlet is connected to the drain port.

[0034] Thus, the cooling water system can pass cooling water into the welding equipment to cool the welding equipment. At the same time, the hot water generated by the heat exchange between the cooling water and the welding equipment is discharged and returned to the cooling water system to achieve water recycling.

In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0052] Laser welding equipment typically requires a chiller for cooling during operation. Specifically, the chiller's low-temperature water cools the laser generator, optical lenses, and other components of the laser welding equipment. Chillers primarily consist of a compressor, condenser, evaporator, throttling device, water pump, and water tank. Their complex structure leads to high costs.

[0053] This application provides a water treatment device for welding equipment. The device can be connected to a water source via a water supply port on a water supply line. Impurities in the water are filtered out by a filter assembly. Water supply parameter detection components detect water supply parameters, ensuring that water supplied to the welding equipment is supplied at preset water supply parameters to cool the welding equipment. Compared to a water chiller, this device eliminates components such as a compressor, evaporator, and condenser, simplifying the structure of the water treatment device for laser welding equipment and reducing the cost of the water cooling system for the laser welding equipment.

[0054] The water treatment device for welding equipment of the present application can be used for cooling but not limited to laser welding equipment, and can also be used for cooling other types of welding equipment.

[0055] For the convenience of explanation, please refer to the following examples. Figure 1 and Figure 2 , a water treatment device 100 of a welding device in some embodiments of the present application is taken as an example for description.

[0056] The water treatment device 100 for welding equipment includes a water supply pipeline 10, a filter assembly 20, and a water supply parameter detection component 30. The water supply pipeline 10 has a water inlet and a water outlet. The water inlet is configured to receive cooling water, and the water outlet is used to supply water to the welding equipment 200. The filter assembly 20 is disposed in the water supply pipeline 10 and is used to filter impurities from the water in the water supply pipeline 10. The water supply parameter detection component 30 is disposed in the water supply pipeline 10, downstream of the filter assembly 20, and is used to detect water supply parameters in the water supply pipeline 10.

[0057] Figure 1 The arrow in the figure indicates the direction of water flow. The upstream port of the water treatment device 100 of the welding equipment is the water supply port, and the downstream port of the water treatment device 100 of the welding equipment connected to the welding equipment is the water outlet.

[0058] Water supply parameters include but are not limited to pressure, temperature, flow rate or flow rate, etc.

[0059] Water supply pipe 10, serving as a water transport channel, has a water inlet at one end for connection to an external water source, such as a municipal water supply line or a dedicated water tank. A water outlet is located at the other end of water supply pipe 10. This outlet is connected to the water inlet of welding equipment 200 via a specific connection method, thereby providing the necessary cooling water for welding equipment 200.

[0060] The filter assembly 20 is installed within the water supply line 10. Its primary function is to filter impurities from the water flowing through the water supply line 10. These impurities may include tiny particles, suspended solids, rust, and other impurities. The filter assembly 20 typically utilizes multiple layers of filter media, such as a filter screen or filter element. This effectively removes impurities from the water through physical interception and adsorption, ensuring that the water entering the welding equipment 200 is relatively pure and preventing impurities from causing damage such as wear and clogging to the internal components of the welding equipment 200.

[0061] “Downstream” refers to the portion of the water supply line 10 where the water continues to flow after passing through a specific component. Taking the filter assembly 20 as an example, the portion of the water supply line 10 after the water passes through the filter assembly 20 is considered downstream of the filter assembly 20.

[0062] The water in the water supply pipe 10 is filtered by the filter assembly 20 to remove impurities, providing clean cooling water for the welding equipment 200, reducing problems such as internal blockage, wear and corrosion of the equipment caused by impurities, thereby maintaining the stability and reliability of the welding equipment 200 and reducing the incidence of equipment failure. Stable and appropriate water supply parameters (such as water temperature, water pressure, flow rate, etc.) help maintain the welding equipment 200 in an ideal working state, which can ensure uniform heat distribution during the welding process, reduce welding defects caused by uneven cooling, and thus reduce the defective rate during the welding process. Therefore, by replacing the existing chiller with a water treatment device 100 having a water supply pipe 10, a filter assembly 20 and a water supply parameter detection component 30, the structure of the water treatment device 100 of the laser welding equipment can be simplified to reduce the cost of the water cooling device of the laser welding equipment 200.

[0063] In some embodiments, please refer to Figure 1 The filter assembly 20 includes a first filter 21 and a second filter 22 , and the first filter 21 is located upstream of the second filter 22 .

[0064] Optionally, the first filter 21 may be, but is not limited to, a Y-type filter. The second filter 22 may be, but is not limited to, a filter having a filter element of less than 75 microns.

[0065] “Upstream” refers to the portion of water flow before it flows to a specific component in the water supply pipe 10. For example, for the second filter 22, the portion of the water supply pipe 10 before the water reaches the second filter 22 is called upstream of the second filter 22.

[0066] The provision of the first filter 21 and the second filter 22 can improve the filtering effect of the water in the water supply pipe 10 to meet the water quality requirements of the laser welding equipment 200 (the water has large impurities, which will affect the service life of the laser welding equipment 200 and the welding quality); at the same time, compared with the structure using only one filter, the maintenance cycle of the filter assembly 20 can be extended.

[0067] In some embodiments, please refer to Figure 1 There are multiple second filters 22, and the multiple second filters 22 are arranged in parallel in the water supply pipeline 10 to form a second filter group. The first filter 21 is located upstream of the second filter group.

[0068] The parallel connection means that the water inlet ends of each second filter 22 are connected to each other, and the water outlet ends of each second filter 22 are connected to each other.

[0069] As a result, the water quality in the water supply pipeline 10 can be further improved, and the maintenance period of the filter assembly 20 can be further shortened.

[0070] In some embodiments, please refer to Figure 1 The water supply parameter detection component 30 includes a flow sensor 31 . The flow sensor 31 is arranged downstream of the filter assembly 20 of the water supply pipeline 10 . The flow sensor 31 is used to detect the water flow in the water supply pipeline 10 .

[0071] The parameters detected by the flow sensor 31 can be fed back to the control component 70, which displays the data detected by the flow sensor 31 through the display component 60. The display component 60 can be a display screen, allowing the operator to directly observe the water flow in the water supply pipeline 10, so that the operator can adjust the water flow in the water supply pipeline 10 according to actual needs. The control component 70 may include a PLC programmable controller.

[0072] The water treatment device 100 needs to supply a predetermined flow of water to the laser welding equipment 200 to ensure cooling of the laser welding equipment 200. The flow sensor 31 can detect the water flow rate of the water supply pipe 10 in real time, ensuring that the water supply pipe 10 can supply the laser welding equipment 200 with the predetermined flow rate.

[0073] In some embodiments, please refer to Figure 1 The water supply parameter detection component 30 includes a flow alarm switch 32, which is arranged downstream of the filter component 20 of the water supply pipeline 10. The flow alarm switch 32 is used to issue an alarm prompt according to the flow not being within the preset flow range.

[0074] The flow alarm switch 32 can be communicatively connected to the control component 70. After receiving the alarm signal from the flow alarm switch 32, the control component 70 will take a series of actions according to preset procedures and strategies. For example, the water supply pipeline 10 can be connected to a water pump, which supplies water to the water supply pipeline 10 through the water pump, and the water pump is communicatively connected to the control component 70. If the control component 70 receives an alarm from the flow alarm switch 32 indicating that the flow rate is too low, the control component 70 can control the water pump to increase the speed to increase the water flow in the water supply pipeline 10; if the flow rate is too high, the control component 70 may appropriately reduce the water pump speed to control the flow rate within a reasonable range.

[0075] When the incoming flow rate is not within the preset flow rate range, the flow alarm switch 32 issues an alarm prompt, and timely adjusts the water flow in the water supply pipe 10, thereby reducing the probability of damage to the laser welding equipment 200 due to too small a flow rate or welding defects due to too large a flow rate.

[0076] In some embodiments, please refer to Figure 1 The water supply parameter detection component 30 includes a temperature sensor 33 . The temperature sensor 33 is disposed downstream of the filter assembly 20 of the water supply pipeline 10 . The temperature sensor 33 is used to detect the water temperature in the water supply pipeline 10 .

[0077] The temperature sensor 33 is communicatively connected to the control unit 70. The control unit 70 displays the temperature value detected by the temperature sensor 33 on the display unit 60, allowing the operator to more directly observe the water temperature in the water supply pipeline 10. When the temperature sensor 33 detects that the water temperature exceeds the preset normal range, it immediately sends an alarm signal to the control unit 70. Upon receiving this signal, the control unit 70 quickly activates the corresponding control strategy. For example, if the water temperature is too high, the control unit 70 can increase the speed of the water pump to adjust the water flow rate to enhance the cooling effect.

[0078] The temperature sensor 33 can provide early warning of abnormal water temperature, which helps to promptly detect faults in the water supply pipeline 10 and reduces the probability of damage to the laser welding equipment 200 or welding defects during the welding process due to excessively high water temperature.

[0079] In some embodiments, please refer to Figure 1 The water supply parameter detection component 30 includes a pressure sensor 34 . The pressure sensor 34 is disposed downstream of the filter assembly 20 of the water supply pipeline 10 . The pressure sensor 34 is used to detect the water pressure in the water supply pipeline 10 .

[0080] The pressure sensor 34 is communicatively connected to the control unit 70. The control unit 70 can display the pressure value detected by the pressure sensor 34 on the display unit 60, allowing the operator to more directly observe the water pressure in the water supply pipeline 10. When the water pressure exceeds a preset normal range, the control unit 70 can control the water pump to reduce the speed. When the water pressure is too low, the control unit 70 can increase the speed of the water pump.

[0081] The pressure sensor 34 provided in the water supply pipeline 10 can detect the water pressure in real time to ensure that a stable water pressure is provided to the laser welding equipment 200. When the pressure fluctuates, it can be adjusted in time to prevent the water pressure from being too low to cause insufficient cooling or the water pressure from being too high to cause damage to the equipment.

[0082] In some embodiments, please refer to Figure 2 The water treatment device 100 of the welding equipment also includes a shell 40, and a receiving space is formed inside the shell 40. Part of the water supply pipeline 10, at least part of the filter assembly 20 and at least part of the water supply parameter detection component 30 are all located in the receiving space.

[0083] Optionally, both the first filter 21 and the second filter 22 may be disposed within the accommodation space, or only one of the first filter 21 and the second filter 22 may be disposed within the accommodation space. The specific configuration may be determined based on the type and occupied space of the first filter 21 and the second filter 22. The water supply port and water outlet of a portion of the water supply pipeline 10 may be disposed outside the housing 40 to facilitate communication between the water source and the water supply port, and between the water outlet and the water inlet of the welding device 200.

[0084] At least one of the flow sensor 31 , the temperature sensor 33 , the pressure sensor 34 and the flow alarm switch 32 in the water supply parameter detection component 30 may be disposed in the accommodation space.

[0085] The housing 40 forms a housing space that integrates at least a portion of the water supply pipeline 10, at least a portion of the filter assembly 20, and at least a portion of the water supply parameter detection component 30, providing a unified installation and protective environment. This reduces damage to these key components from external environmental factors, such as dust and physical impact. Furthermore, the water supply pipeline 10, filter assembly 20, and water supply parameter detection component 30 are all located within the same housing space, making maintenance and inspection more convenient. Maintenance personnel can inspect, repair, and replace each component in a relatively centralized area, improving work efficiency.

[0086] In some embodiments, please refer to Figure 2 At least one side wall of the shell 40 is a transparent wall.

[0087] The transparent wall may be, but is not limited to, a glass plate or an acrylic plate.

[0088] The provision of the transparent wall can facilitate maintenance personnel to check the operating status of the water supply parameter detection component 30 in a timely manner, so as to facilitate positioning and regular maintenance of the water supply parameter detection component 30.

[0089] In some embodiments, please refer to Figure 2 A water receiving tray 41 is provided inside the shell 40 . The water receiving tray 41 is located below the filter assembly 20 and is used to receive water discharged from the filter assembly 20 .

[0090] The setting of the water receiving tray 41 effectively receives the water discharged from the filter assembly 20, reducing the probability of water dripping directly onto the ground or other equipment, thereby reducing the probability of the ground being slippery and the equipment being damp due to water leakage, and reducing potential safety hazards and equipment damage risks.

[0091] In some embodiments, please refer to Figure 1The water treatment device 100 of the welding equipment further includes a first valve 50 , which is disposed upstream of the filter assembly 20 of the water supply pipeline 10 , and is used to open or close the water supply pipeline 10 .

[0092] The first valve 50 can conveniently open or close the water supply pipeline 10 to achieve precise control of the water supply. For example, during equipment maintenance or overhaul, the valve can be closed to stop the water supply to ensure the safety of the operator and the smooth progress of the work. Assuming that when the filter assembly 20 is replaced, closing the first valve 50 can prevent the water from continuing to flow through, avoiding water leakage and interference with maintenance work. When an emergency occurs in the water supply pipeline 10, such as leakage, rupture, etc., the first valve 50 can be quickly closed to prevent the water from continuing to leak, reducing losses and dangers. By properly controlling the opening of the first valve 50, the water supply pressure in the water supply pipeline 10 can be adjusted to a certain extent to meet the needs under different working conditions.

[0093] For the convenience of description, the following embodiments are described by taking a welding system according to some embodiments of the present application as an example.

[0094] Please refer to Figure 1 and Figure 2 The welding system includes a welding device 200 and the water treatment device 100 of the welding device of the above embodiment. The welding device 200 has a water inlet and a drain. The water inlet is connected to the water outlet of the water supply pipeline 10.

[0095] In one embodiment, the welding device 200 is further provided with a drain outlet, which is connected to a drain pipe 210 . The drain pipe 210 is provided with a second valve 220 , which is used to open or close the drain pipe 210 .

[0096] As an example, the welding device 200 may be a laser welding device or a medium frequency welding machine.

[0097] The welding machine's main unit is equipped with a heat exchanger. The heat exchanger's heat exchange medium inlet serves as the welding machine's water inlet, and the heat exchange medium outlet serves as the welding machine's drain outlet. The heat exchanger is used to cool the laser generator within the welding machine or the transformer of the medium-frequency welding machine.

[0098] In some embodiments, the welding equipment 200 is also provided with a drain outlet, and the welding system further includes a cooling water system 300, which is provided with a cooling water outlet and a circulating water inlet. The cooling water outlet is connected to the water supply port, and the circulating water inlet is connected to the drain outlet.

[0099] The circulating water inlet can be connected to the drain outlet through the drain pipe 210 .

[0100] As an example, cooling water system 300 includes a compressor, an evaporator, a condenser, a throttle valve, and a cooling water storage component. The compressor, condenser, throttle valve, and evaporator are connected by pipelines. The specific connection structure is generally similar to the piping structure of an air conditioner. The evaporator has two flow channels: one for refrigerant and the other for water, enabling heat exchange between water and refrigerant. Condensed water generated by the evaporator can be piped into the cooling water storage component for storage. The cooling water in the cooling water storage component can be supplied to the water supply port. The cooling water storage component can be a storage tank or storage tank, etc.

[0101] Since the welding system includes all the technical features of the water treatment device 100 of the above embodiment, the effects are the same as those described above and will not be described in detail here.

[0102] In an alternative embodiment of the water treatment device 100, please refer to Figure 2The water treatment device 100 for welding equipment includes a first valve 50, a housing 40, a water receiving tray 41, a water supply line 10, a filter assembly 20, a display unit 60, and a water supply parameter detection unit 30. The water supply line 10 has a water inlet and a water outlet, with the water outlet being used to supply water to the welding equipment 200. The filter assembly 20 is disposed in the water supply line 10 and is used to filter impurities from the water within the water supply line 10. The filter assembly 20 includes a first filter 21 and a second filter 22, with the first filter 21 located upstream of the second filter 22. There are two second filters 22, which are disposed in parallel in the water supply line 10 to form a second filter group, with the first filter 21 located upstream of the second filter group. The water supply parameter detection unit 30 is disposed in the water supply line 10, downstream of the filter assembly 20, and is used to detect water supply parameters within the water supply line 10. The water supply parameter detection component 30 includes a flow sensor 31, a temperature sensor 33, a pressure sensor 34, a control component 70, and a flow alarm switch 32. The flow sensor 31 is located downstream of the filter assembly 20 in the water supply pipeline 10 and is used to detect the water flow rate within the water supply pipeline 10. The flow alarm switch 32 is located downstream of the filter assembly 20 in the water supply pipeline 10 and is used to issue an alarm if the flow rate is not within a preset flow range. The temperature sensor 33 is located downstream of the filter assembly 20 in the water supply pipeline 10 and is used to detect the water temperature within the water supply pipeline 10. The pressure sensor 34 is located downstream of the filter assembly 20 in the water supply pipeline 10 and is used to detect the water pressure within the water supply pipeline 10. The flow sensor 31, temperature sensor 33, pressure sensor 34, display component 60, and flow alarm switch 32 are each communicatively connected to the control component 70. The control component 70 can send the water supply parameters detected by the flow sensor 31, the temperature sensor 33 and the pressure sensor 34 to the display component 60, so that the display component 60 displays the water supply parameters, and send flow abnormality information to the display component 60, so that the display component 60 displays the flow abnormality information. A accommodating space is formed inside the shell 40, and the water supply pipeline 10, the filter assembly 20 and the water supply parameter detection component 30 are all located in the accommodating space. At least one side wall of the shell 40 is a transparent wall. A water receiving tray 41 is provided inside the shell 40, and the water receiving tray 41 is located below the filter assembly 20 for receiving water discharged from the filter assembly 20. The first valve 50 is provided upstream of the filter assembly 20 of the water supply pipeline 10, and the first valve 50 is used to open or close the water supply pipeline 10.

[0103] The water in the water supply pipe 10 is filtered by the filter assembly 20 to remove impurities, providing clean cooling water for the welding equipment 200, reducing problems such as internal blockage, wear and corrosion of the equipment caused by impurities, thereby maintaining the stability and reliability of the welding equipment 200 and reducing the incidence of equipment failure. Stable and appropriate water supply parameters (such as water temperature, water pressure, flow rate, etc.) help maintain the welding equipment 200 in an ideal working state, which can ensure uniform heat distribution during the welding process, reduce welding defects caused by uneven cooling, and thus reduce the defective rate during the welding process. Therefore, by replacing the existing chiller with a water treatment device 100 having a water supply pipe 10, a filter assembly 20 and a water supply parameter detection component 30, the structure of the water treatment device 100 of the laser welding equipment can be simplified to reduce the cost of the water cooling device of the laser welding equipment 200. The accommodation space formed inside the shell 40 integrates the water supply pipeline 10, the filter assembly 20 and the water supply parameter detection component 30, providing a unified installation and protection environment, reducing the damage to these key components caused by external environmental factors, such as dust, physical collisions, etc.; at the same time, the water supply pipeline 10, the filter assembly 20 and the water supply parameter detection component 30 are all located in the same accommodation space, making maintenance and inspection work more convenient. Maintenance personnel can inspect, repair and replace each component in a relatively concentrated area, thereby improving work efficiency. The setting of the transparent wall can facilitate maintenance personnel to check the operating status of the water supply parameter detection component 30 in a timely manner, so as to facilitate the positioning of the water supply parameter detection component 30 for regular maintenance. The setting of the water receiving tray 41 effectively receives the water discharged by the filter assembly 20, reducing the probability of water dripping directly onto the ground or other equipment, thereby reducing the probability of the ground being slippery and the equipment being damp due to water leakage, and reducing potential safety hazards and equipment damage risks.
