Description

Technical Field

[0001] The present application relates to the field of medical device precision processing equipment and application technology, and in particular to a self-regulating processing reagent circulating water tank applied to a laser multi-energy composite processing system for precision thin-walled metal tube or flat device. Background Art

[0002] At present, in order to improve the thermal impact and burrs on the back side of the incision (also known as slag and flash) during laser micromachining and maximize the incision quality, medical stents, endoscope snake bones, laparoscope sleeves and other precision thin-walled metal tube instruments usually adopt laser wet cutting technology. That is, while laser processing the precision thin-walled metal tube instruments, a processing reagent is introduced into the precision thin-walled metal tube to facilitate the timely removal of the processing heat at the processing point and the slag in the tube.

[0003] Similar to this is the water-conducting laser processing technology, which is to pass a processing agent of a certain pressure into the laser cutting head during the processing, so that the impact force of the processing agent and the coaxially emitted laser energy work together to achieve material removal. This processing technology requires the processing agent to be pressurized to a certain pressure, and the laser energy mainly acts near the surface of the material, but the processing agent of a certain pressure is sprayed downward. When the inner diameter of the precision thin-walled metal tube is small, it is very easy to cause damage to the inner side of the precision thin-walled metal tube on the symmetrical surface at the processing point. Therefore, this processing technology is mainly used for the processing of precision thin-walled metal tubes with large inner diameters or flat instruments to ensure that the symmetrical tube wall will not be affected during processing. In addition, the processing agent used in this processing technology mainly needs to increase the quantitative pressure and filter the processing agent at the same time, but there is no function to control the temperature and purity of the processing agent during the circulating filtration of the processing agent.

[0004] Since the chemical reagent circulating water tank used in the above scheme does not have the function of controlling temperature and adjusting the concentration of chemical reagents, it is not suitable for plane equipment processing.

[0005] The chemical reagent circulating water tank traditionally used in medical device laser micromachining systems only provides processing reagents to precision thin-walled metal tubes. The circulating processing reagents are only filtered without self-regulating the temperature and purity. They are not suitable for planar device processing applications, and do not provide processing reagents with self-regulating performance and status for the circulation of multi-energy fine laser cutting heads. Utility Model Content

[0006] The main purpose of this application is to provide a processing reagent circulating water tank, which has the ability to simultaneously provide processing reagents with stable performance and state to the circulation of precision thin-walled metal tubes and multi-energy fine laser cutting heads, and the device has the functions of automatically filtering the circulating processing reagents, automatically measuring and adjusting the temperature, automatically controlling the processing reagent output pressure, and automatically regulating the performance and state of the processing reagents, ensuring that the processing reagents output by the device have stable performance and state in the same product processing, thereby achieving the stability of the laser multi-energy composite processing process for precision thin-walled metal tubes or plane-type instruments. At the same time, the device is not only suitable for the laser multi-energy processing application of precision thin-walled metal tubes, but also for the laser multi-energy processing application of plane-type instruments. It has a modular integrated design, a reasonable appearance and layout, and can be independently placed outside the laser multi-energy processing system, or inherited from the laser multi-energy processing system. It has a wide market application prospect in the fields of laser micro-processing of precision instruments such as medical, automotive, semiconductor, electronics, aerospace, military, and smart appliances.

[0007] In order to achieve the above-mentioned objectives, in the first aspect, the present application provides a processing reagent circulating water tank, comprising a box body, a liquid storage box arranged in the box body, the liquid storage box is connected to one end of a liquid outlet pipe, the liquid outlet pipe is provided with a reagent output power system, the liquid storage box is connected to one end of a liquid inlet pipe, and the box body is also provided with a temperature monitoring module, a reagent output pressure monitoring module, a chemical property status monitoring module, a reagent constant temperature control system, a reagent automatic proportioning system and a controller, and the controller is respectively connected to the temperature monitoring module, the reagent output pressure monitoring module, the chemical property status monitoring module, the reagent constant temperature control system, and the reagent automatic proportioning system by electrical signals.

[0008] As a further improvement, the reagent output power system includes a power pump and a frequency converter connected to the power pump.

[0009] A further improvement is that the reagent constant temperature control system includes a reagent heating module and a reagent cooling module.

[0010] As a further improvement, a reagent level monitoring module for monitoring the liquid level is further provided in the liquid storage box, and the controller is electrically connected to the reagent level monitoring module.

[0011] As a further improvement, a liquid leakage sensing monitoring module and an alarm are also provided in the box, and the controller is electrically connected to the liquid leakage sensing monitoring module and the alarm respectively.

[0012] A further improvement is that a filtering structure is provided at the connection between the liquid inlet pipe and / or the liquid outlet pipe and the liquid storage box.

[0013] A further improvement is that the filtering structure is filter cotton with a filtering particle size of 10 um.

[0014] A further improvement is that the inner walls of the box body, the liquid storage box, the liquid inlet pipe, and the liquid outlet pipe are all provided with an anti-corrosion layer.

[0015] A further improvement is that the reagent heating module is an electric heating rod.

[0016] The utility model provides a processing reagent circulating water tank, which has the beneficial effect, compared with the prior art, that the processing reagent circulating water tank can realize automatic and precise regulation of the performance and state of the processing reagent flowing through the precision thin-walled metal tube during the laser multi-energy composite processing of the precision thin-walled metal tube by monitoring and adjusting the real-time state of the processing reagent, thereby achieving high stability of the laser multi-energy composite processing performance.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figure 1-Figure 2 As shown, a processing reagent circulating water tank includes a box body 2, a liquid storage box 3 arranged in the box body 2, the liquid storage box 3 is connected to one end of a liquid outlet pipe, the liquid outlet pipe is provided with a reagent output power system, the liquid storage box 3 is connected to one end of a liquid inlet pipe, and the box body 2 is also provided with a temperature monitoring module 6, a reagent output pressure monitoring module 7, a chemical property status monitoring module 8, a reagent constant temperature control system, a reagent automatic proportioning system 11 and a controller 12, and the controller 12 is respectively connected to the temperature monitoring module 6, the reagent output pressure monitoring module 7, the chemical property status monitoring module 8, the reagent constant temperature control system, and the reagent automatic proportioning system 11 with electrical signals.

[0028] Among them, the controller 12 is configured to receive the detection signal of the temperature monitoring module 6, and control the reagent constant temperature control system to heat or cool the reagent in the liquid storage box 3 based on the preset temperature; receive the detection signal of the reagent output pressure monitoring module 7, and control the reagent output power system to open, close and adjust based on the preset pressure; receive the detection signal of the chemical performance status monitoring module 8, and control the reagent automatic proportioning system 11 to supplement the chemical components in the chemical reagent based on the preset concentration. It should be noted that the controller 12 controls the actions of other components based on the detection signal of the detection component, which belongs to the conventional design of mechanical automation and does not involve computer software control. Moreover, the above-mentioned detection and controller 12 are all purchased parts, and their specific working principles and structures are not the design points of this application. As long as the structure can achieve the above functions, it can be adopted. It is just a difference in model, so its specific structure will not be repeated here.

[0029] Preferably, the reagent output power system includes a power pump 4 and a frequency converter 5 connected to the power pump 4. The frequency converter 5 mainly controls the output power of the power pump 4, thereby realizing the pressure control of the chemical reagent. Control logic: The reagent output pressure monitoring module 7 is used to measure and monitor in real time whether the input processing reagent pressure meets the requirements. If there is an abnormality, the electronic flow meter in the reagent output pressure monitoring module 7 will automatically alarm, and the power pump 4 will stop working at this time. Only when the pressure of the output processing reagent is within the normal range, the processing reagent output power pump 4 can be triggered to work, and it can also be regulated by the frequency converter 5.

[0030] Preferably, the reagent constant temperature control system comprises a reagent heating module 9 and a reagent refrigeration module 10, wherein the reagent heating module 9 is an electric heating rod, and the reagent refrigeration module 10 uses a refrigerant for cooling.

[0031] In order to monitor the liquid level of chemical agents in real time, a reagent level monitoring module 13 for monitoring the liquid level is also provided in the liquid storage tank 3. The controller 12 is electrically connected to the reagent level monitoring module 13. The controller 12 is configured to receive the reagent level monitoring module 13 and control the output power system to be turned on or off based on a preset liquid level.

[0032] Specifically, wherein the reagent level monitoring module 13 mainly monitors the liquid level height, and the liquid level real-time monitor can be used to monitor, when the processing reagent stores a certain amount above the liquid level safety warning line, the power pump 4 will work automatically, and the processing reagent of a certain pressure is continuously exported in the precision thin-walled metal tube, and when the storage amount of the processing reagent falls back to the liquid level safety warning line, the liquid level real-time monitor will alarm, and the power pump 4 will stop working at the same time, until a certain amount of processing reagent is added manually, the liquid level real-time monitor alarm is released, and the power pump 4 will work again. The temperature monitoring module 6 is mainly used for monitoring the temperature change of the processing reagent, and only the processing reagent temperature is within the controllable range, and the power pump 4 can be triggered to work. If the processing reagent temperature is too high, the refrigerant of the reagent refrigeration module 10 can be triggered to work, until the processing reagent temperature is too high and the alarm is released, otherwise if the processing reagent temperature is too low, the electric heating rod of the reagent heating module 9 can be triggered to work, until the processing reagent temperature is too low and the alarm is released, monitor the temperature of the processing reagent working time by the reagent constant temperature control system to see whether it meets the processing demand, and only when the temperature is normal, the power pump 4 can be triggered to work.

[0033] Through the above working principle, the processing reagent circulation water tank realizes automatic regulation of the performance and state of the processing reagent flowing through the precision thin-walled metal tube during the laser multi-energy composite processing of the precision thin-walled metal tube, thereby achieving high stability of the laser multi-energy composite processing performance.

[0034] In addition, in order to maintain the sealing requirements of the system, a liquid leakage sensing monitoring module 14 and an alarm are also provided in the box body 2, and the controller 12 is electrically connected to the liquid leakage sensing monitoring module 14 and the alarm respectively.

[0035] A filter structure is provided at the connection between the liquid inlet pipe and / or the liquid outlet pipe and the liquid storage box 3. Preferably, the filter structure is a filter cotton with a filter particle size of 10 um.

[0036] Finally, since chemical agents are corrosive to a certain extent, chemical agents are generally a certain dose of oxalic acid, hydrofluoric acid, and nitric acid to form a cleaning solution, so the inner walls of the box body 2, the liquid storage box 3, the liquid inlet pipe, and the liquid outlet pipe are all provided with an anti-corrosion layer.

[0037] Preferably, the chemical performance status monitoring module 8 includes a reagent concentration detector 15 for detecting concentration and a chemical analyzer 16 for analyzing chemical composition, which are arranged in the liquid storage box 3; the reagent automatic proportioning system 11 includes a proportioning power pump 1 and a proportioning solution storage box 17. When controlling the composition and concentration of chemical reagents, the chemical performance status monitoring module 8 and the reagent automatic proportioning system 11 are mainly used to automatically determine whether the chemical cost of the processing reagent used as the cleaning liquid meets the proportioning requirements. If it does not meet the requirements, the reagent automatic proportioning system 11 will automatically inject a certain amount of chemical reagents into the liquid storage box 3 until the final cleaning liquid meets the standard proportioning requirements. In this process, the chemical performance status monitoring module 8 is in an alarm state, and the power pump 4 is always in a stopped working state. After meeting the requirements, the alarm of the chemical performance status monitoring module 8 is released, and the power pump 4 can work normally. Specifically, the concentration of the chemical reagent is first detected by the reagent concentration detector 15, and the chemical analyzer 16 analyzes the proportion of each component in the current chemical reagent, and then the missing chemical components are supplemented by controlling the proportioning power pump 1. Of course, when the concentration is too low, the chemical reagent as a whole can also be directly supplemented.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
