Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, in particular to a detection mechanism and a liquid medicine temperature regulating device. Background Art

[0002] PCBs (Printed Circuit Boards), also known as printed circuit boards, have a complex manufacturing process, some of which require the use of chemicals, which must be heated or cooled to the appropriate temperature. This heating and cooling process typically involves the use of thermostats. However, prolonged use of thermostats can lead to surface leakage, allowing chemical liquid to enter the thermostat, potentially corroding the thermostat and the external controller.

[0003] In the prior art, a pH probe is usually used to control and detect the pH value of the regulating liquid inside the thermostatic tube assembly and provide an alarm. However, during the long-term use of the thermostatic tube assembly, scale and impurities will be generated inside the thermostatic tube assembly, making the pH probe easily adhered or blocked by foreign matter. In addition, the pH probe uses potentiometric analysis to detect the acid-base concentration of the regulating liquid. Its electrode is a primary battery that converts chemical energy into electrical energy, resulting in a relatively short probe life, prone to false alarms, and inaccurate detection. Utility Model Content

[0004] The purpose of the utility model is to provide a detection mechanism and a medicine temperature regulating device, which have a long service life and a high detection accuracy.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The detection mechanism is used to detect leakage of the liquid medicine temperature regulating device, wherein the liquid medicine temperature regulating device includes a temperature regulating tube assembly, including:

[0007] An electrode assembly, wherein the detection electrode in the electrode assembly is disposed in the temperature regulating tube assembly, and the electrode assembly is communicatively connected to an external PLC (programmable logic controller), and the temperature regulating tube assembly is configured to regulate the temperature in the chemical tank via a regulating fluid;

[0008] When the thermostatic tube assembly leaks, the conductivity of the regulating fluid in the thermostatic tube assembly changes, so that the detection electrode is turned on and a leakage signal is sent to the external PLC.

[0009] As a further technical solution, the electrode assembly also includes an electrode seat, a variable resistor and a shell. The electrode seat is arranged in the shell. Two detection electrodes are arranged on the electrode seat at intervals. The variable resistor is arranged on the side of the electrode seat away from the two detection electrodes, and is conductive with the two detection electrodes. The shell is connected to the liquid outlet pipe in the temperature control tube assembly.

[0010] As a further technical solution, the electrode assembly further includes a prompting member, and the prompting member is communicatively connected with the detection electrode and / or the PLC.

[0011] As a further technical solution, the detection mechanism further includes a connecting assembly, and the housing is arranged on the liquid outlet pipe through the connecting assembly.

[0012] As a further technical solution, the connecting assembly includes a connecting piece, the connecting piece is provided with a first connecting pipe, a second connecting pipe and a third connecting pipe that are interconnected, and the liquid outlet pipe is provided with a liquid outlet portion and a connecting portion;

[0013] The liquid outlet is connected to the first communicating tube, the communicating portion is connected to the second communicating tube, the housing is connected to the third communicating tube, and both of the detection electrodes are located in the third communicating tube.

[0014] As a further technical solution, inner walls of the first communicating tube and the second communicating tube are both provided with limiting steps, and the liquid outlet portion and the communicating portion are respectively in contact with the corresponding limiting steps.

[0015] As a further technical solution, the connecting assembly also includes an auxiliary connecting tube and a connecting sleeve. The first end of the auxiliary connecting tube is detachably connected to the third connecting tube. The connecting sleeve is connected to the second end of the auxiliary connecting tube and is sleeved on one end of the outer shell close to the connecting piece so that the second end of the auxiliary connecting tube abuts against the outer shell.

[0016] As a further technical solution, the connection assembly further includes a sealing ring, which is arranged between the second end of the auxiliary connecting pipe and the outer shell.

[0017] The medicine temperature regulating device includes a temperature regulating tube assembly and a detection mechanism. The temperature regulating tube assembly also includes a liquid inlet pipe, a liquid outlet pipe and a coil. The liquid inlet pipe and the liquid outlet pipe are detachably connected to the coil. The coil is arranged in the medicine tank. The external regulation host can change the temperature of the regulating liquid in the temperature regulating tube assembly to achieve temperature regulation of the medicine in the medicine tank. The detection mechanism is arranged on the liquid outlet pipe.

[0018] As a further technical solution, the temperature regulating pipe assembly further includes at least one valve, which is arranged on the liquid inlet pipe and / or the liquid outlet pipe.

[0019] Compared with the existing technology, the detection mechanism and the liquid medicine temperature regulating device provided by the present invention have the following technical advantages:

[0020] Since the detection electrodes are located within the thermostatic tube assembly, if a leak develops within the thermostatic tube assembly, the liquid medicine in the liquid medicine tank will flow through the leak point into the thermostatic tube assembly, thereby changing the conductivity of the conditioning fluid within the thermostatic tube assembly. When the conditioning fluid mixed with the liquid medicine flows to the detection electrodes, the detection electrodes conduct and send a leakage signal to the PLC, alerting the operator to a leak in the thermostatic tube assembly. Throughout this process, accumulated scale and impurities within the thermostatic tube assembly will not affect the detection electrodes, nor will they cause adhesion or blockage. Furthermore, the detection mechanism determines whether the thermostatic tube assembly is leaking by detecting the conductivity of the conditioning fluid within the thermostatic tube assembly using the detection electrodes. This ensures the service life of the detection mechanism and avoids false alarms, guaranteeing effective detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0029] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0030] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0031] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0032] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0033] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts.

For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0035] Combine Figure 1 and Figure 2 As shown, the detection mechanism and liquid medicine temperature control device provided in this embodiment have a long service life and high detection accuracy. Specifically, the liquid medicine temperature control device includes a temperature control tube assembly 100 and a detection mechanism. The temperature control tube assembly 100 is disposed within the liquid medicine tank 10 and is connected to an external control host. The control host can change the temperature of the regulating liquid within the temperature control tube assembly 100 to achieve temperature regulation of the liquid medicine within the liquid medicine tank 10. The detection mechanism includes an electrode assembly 210. The detection electrode 211 in the electrode assembly 210 is disposed within the liquid outlet pipe 110 of the temperature control tube assembly 100 and is communicatively connected to an external PLC. When the temperature control tube assembly 100 leaks, the conductivity of the regulating liquid within the temperature control tube assembly 100 changes, causing the detection electrode 211 to conduct and transmit a leakage signal to the PLC.

[0036] In this embodiment, the temperature control tube assembly 100 is connected to an external control unit and is located within the chemical solution tank 10. During the PCB fabrication process, the control unit can inject conditioning fluids of varying temperatures into the temperature control tube assembly 100, depending on the PCB fabrication step. This allows the temperature control tube assembly 100 to be heated or cooled, thereby adjusting the temperature of the chemical solution within the chemical solution tank 10 to the desired temperature for the current process.

[0037] Because the detection electrode 211 is disposed within the thermostatic tube assembly 100, when the temperature of the conditioning liquid in the thermostatic tube assembly 100 is altered to regulate the temperature of the liquid in the liquid tank 10, a negative pressure environment is created within the thermostatic tube assembly 100 as the conditioning liquid flows within the thermostatic tube assembly 100. Consequently, if a leak develops within the thermostatic tube assembly 100, the liquid in the liquid tank 10 will enter the thermostatic tube assembly 100 through the leak, thereby changing the conductivity of the conditioning liquid within the thermostatic tube assembly 100. When the conditioning liquid mixed with the liquid flows to the detection electrode 211, the detection electrode 211 conducts and sends a leakage signal to the PLC, alerting the operator to a leak in the thermostatic tube assembly 100. During the entire process, the scale and impurities accumulated inside the thermostatic tube assembly 100 will not affect the detection electrode 211, nor will they cause adhesion or blockage of the detection electrode 211. The detection mechanism detects the conductivity of the regulating liquid in the thermostatic tube assembly 100 through the detection electrode 211 to determine whether the thermostatic tube assembly 100 is leaking, thereby ensuring the service life of the detection mechanism and avoiding false alarms to ensure the detection effect.

[0038] The liquid medicine temperature regulating device includes a temperature regulating tube assembly 100 and a detection mechanism. The temperature regulating tube assembly 100 also includes a liquid inlet pipe 120 and a coil 130 . The liquid inlet pipe 120 and the liquid outlet pipe 110 are detachably connected to the coil 130 .

[0039] Combine Figure 1 As shown, the coil 130 is located in the medicine tank 10, which can increase the contact area with the medicine in the medicine tank 10, thereby improving the efficiency of temperature regulation of the medicine in the medicine tank 10; and since the liquid inlet pipe 120 and the liquid outlet pipe 110 are detachably connected to the coil 130, therefore, as the working time of the temperature regulating tube assembly 100 increases, when the coil 130 leaks, the leaking coil 130 can be directly removed from the liquid inlet pipe 120 and the liquid outlet pipe 110, and only the coil 130 needs to be replaced without replacing the entire temperature regulating tube assembly 100, thereby ensuring the temperature regulation effect of the medicine in the medicine tank 10 while reducing the cost of use.

[0040] Preferably, the electrode assembly 210 also includes an electrode seat 212, a variable resistor 213 and a shell 214. The electrode seat 212 is arranged in the shell 214. Two detection electrodes 211 are arranged on the electrode seat 212 at intervals. The variable resistor 213 is arranged on the side of the electrode seat 212 away from the two detection electrodes 211, and both are conductive with the two detection electrodes 211. The shell 214 is connected to the liquid outlet pipe 110.

[0041] Specific combination Figure 2 As shown, both detection electrodes 211 are sheathed with insulating outer tubes. When a leak occurs in the thermostatic tube assembly 100, the liquid medicine in the liquid medicine tank 10 enters the thermostatic tube assembly 100 through the leak point. The liquid medicine mixes with the conditioning liquid in the thermostatic tube assembly 100, causing the conductivity of the mixed liquid to increase and the resistance to decrease, thereby causing the two detection electrodes 211 to conduct. The current signal is then transmitted to the variable resistor 213 through the electrode holder 212 after current limiting by the corresponding insulating outer tube. After fine-tuning by the variable resistor 213, the leakage signal is transmitted to the PLC, alerting the operator to the presence of a leak in the thermostatic tube assembly 100. The outer shell 214 ensures the structural integrity and operational safety of the electrode assembly 210. Furthermore, since the electrode assembly 210 is located within the liquid outlet pipe 110, the electrode assembly 210 improves the timeliness and accuracy of detecting leaks in the thermostatic tube assembly 100.

[0042] Furthermore, the electrode assembly 210 further includes a prompting member, which is communicatively connected to the detection electrode 211 and / or the PLC.

[0043] Specifically, a prompting member is provided on the chemical solution tank 10 or the housing 214. When the thermostatic tube assembly 100 leaks, a leakage signal is synchronously transmitted to the prompting member, which then issues a prompt, allowing the operator to promptly understand the specific condition of the thermostatic tube assembly 100. Depending on actual needs, the prompting member can be configured as a light prompting member. When the thermostatic tube assembly 100 is not leaking, the light prompting member is silent or emits a green light. When the thermostatic tube assembly 100 is leaking, the light prompting member emits a red light. Alternatively, the prompting member can be configured as an audible prompting member, emitting different sound effects to indicate different conditions of the thermostatic tube assembly 100. Alternatively, the prompting member can be configured as both a light prompting member and an audible prompting member.

[0044] In this embodiment, in order to reduce the difficulty of installing the electrode assembly 210 on the liquid outlet pipe 110 and ensure the installation strength and stability of the electrode assembly 210 on the liquid outlet pipe 110, the detection mechanism also includes a connecting assembly 220, and the outer shell 214 is arranged on the liquid outlet pipe 110 through the connecting assembly 220.

[0045] Specifically, the connecting component 220 includes a connecting member 221, which is provided with a first connecting tube 2211, a second connecting tube 2212 and a third connecting tube 2213 that are interconnected, and the liquid outlet pipe 110 is provided with a liquid outlet portion 111 and a connecting portion 112; the liquid outlet portion 111 is connected to the first connecting tube 2211, the connecting portion 112 is connected to the second connecting tube 2212, the outer shell 214 is connected to the third connecting tube 2213, and the two detection electrodes 211 are both located in the third connecting tube 2213.

[0046] Combine Figure 2 As shown, the connector 221 is configured as a three-way pipe. When the regulating liquid flows into the connector 221 through the liquid outlet 111, the regulating liquid passes through the electrode assembly 210 provided in the third connecting pipe 2213, thereby ensuring that the electrode assembly 210 accurately and promptly detects leakage of the temperature regulating tube assembly 100. At the same time, the regulating liquid can flow back into the regulating host through the connecting portion 112 provided in the second connecting pipe 2212, thereby ensuring the smooth temperature regulation process of the liquid medicine in the liquid medicine tank 10. The three-way pipe ensures the convenience of installing the electrode assembly 210 on the liquid outlet pipe 110 and the connection effect.

[0047] Furthermore, inner walls of the first communicating tube 2211 and the second communicating tube 2212 are both provided with limiting steps 2201 , and the liquid outlet portion 111 and the communicating portion 112 are respectively in contact with the corresponding limiting steps 2201 .

[0048] Combine Figure 1 and Figure 2 As shown, in this embodiment, the first connecting tube 2211 and the second connecting tube 2212 are arranged opposite to each other, that is, the connecting piece 221 is in the shape of a "⊥". Since the limiting steps 2201 are provided on the inner walls of the first connecting tube 2211 and the second connecting tube 2212, when the liquid outlet 111 is connected to the first connecting tube 2211 and the connecting part 112 is connected to the second connecting tube 2212, the liquid outlet 111 and the connecting part 112 are respectively abutted against the corresponding limiting steps 2201, which can avoid the liquid outlet 111 and the connecting part 112 from directly docking, thereby avoiding the regulating liquid flowing through the liquid outlet tube 110 from being unable to contact the detection electrode 211, which may cause the detection electrode 211 to fail or the detection result to be inaccurate.

[0049] Preferably, the connecting assembly 220 also includes an auxiliary connecting tube 223 and a connecting sleeve 224. The first end of the auxiliary connecting tube 223 can be detachably connected to the third connecting tube 2213. The connecting sleeve 224 is connected to the second end of the auxiliary connecting tube 223 and is sleeved on one end of the outer shell 214 close to the connecting piece 221 so that the second end of the auxiliary connecting tube 223 abuts against the outer shell 214.

[0050] Combine Figure 1 and Figure 2As shown, the first end of the auxiliary connecting tube 223 is threadedly connected to the third connecting tube 2213. Therefore, when the type of liquid medicine in the liquid medicine tank 10 changes, the third connecting tube 2213 can be used to connect with the corresponding auxiliary connecting tube 223 to replace the electrode assembly 210 of different specifications, thereby ensuring that the detection electrode 211 can promptly and accurately detect whether the temperature control tube assembly 100 placed in different types of liquid medicine has leaked. The connecting sleeve 224 connects the second end of the auxiliary connecting tube 223 to the outer shell 214, ensuring the stability and strength of the connection between the two while ensuring the sealing between the auxiliary connecting tube 223 and the outer shell 214.

[0051] In order to further improve the sealing between the auxiliary connecting tube 223 and the outer shell 214, and prevent the regulating liquid or the regulating liquid mixed with medicine from leaking out from between the auxiliary connecting tube 223 and the outer shell 214, so as to ensure the detection accuracy and detection safety of the electrode assembly 210, in this embodiment, the connecting assembly 220 also includes a sealing ring 225, which is arranged between the second end of the auxiliary connecting tube 223 and the outer shell 214.

[0052] Preferably, the temperature regulating tube assembly 100 further includes at least one valve 140 , which is disposed on the liquid inlet pipe 120 and / or the liquid outlet pipe 110 .

[0053] Combine Figure 1 As shown, in this embodiment, valve 140 is configured as a solenoid valve and is installed on the liquid inlet pipe 120. The solenoid valve is communicatively connected to the PLC. When the control unit injects a temperature-controlled liquid into the coil 130 through the liquid inlet pipe 120, the temperature of the liquid in the liquid tank 10 is adaptively adjusted by controlling the on / off state, on / off duration, and flow direction of the solenoid valve. When the detection electrode 211 detects a leak in the coil 130, it transmits a leakage signal to the PLC, which controls the solenoid valve to close, restricting the flow of the liquid in the control unit into the coil 130 and stopping the flow of the liquid in the temperature control tube assembly 100. This prevents the liquid in the liquid tank 10 from continuing to enter the coil 130, thereby reducing corrosive damage to the liquid outlet pipe 110 and the control unit.

[0054] In other embodiments, the solenoid valve may also be provided on the liquid outlet pipe 110; or, solenoid valves may be provided on both the liquid inlet pipe 120 and the liquid outlet pipe 110; or, the valve 140 may also be provided as a manual valve 140 according to actual needs.

[0055] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
