Description

Technical Field

[0001] The present application relates to the technical field of product processing equipment, and in particular to a pressure maintaining equipment. Background Art

[0002] During the manufacturing process of a product, in order to improve the assembly accuracy between product components, the durability of the product, and the consistency of product quality, pressure holding equipment is usually used to process the product in the production process.

[0003] Specifically, pressure-holding equipment typically applies uniform pressure to tightly bond two or more components during assembly, ensuring a secure and reliable connection, good sealing, and waterproofing between components. This ensures the required assembly precision is achieved, minimizing failures and quality issues caused by loose components or poor assembly. At the same time, critical parts must possess sufficient structural strength to withstand the various stresses of daily use. Pressure-holding equipment can apply pressure to these areas, tightening the bond between materials and enhancing structural strength and product durability. For example, pressure-holding can improve impact and vibration resistance.

[0004] In the related art, pressure-maintaining equipment is generally manually operated to apply pressure to the product to be processed. Therefore, there are problems such as the magnitude of the applied pressure is not stable enough, the pressurization time cannot be accurately controlled, and the pressure parameters applied to different batches of products are different, which easily lead to problems such as poor assembly effect, unstable assembly effect, and low yield. Utility Model Content

[0005] The purpose of this application is to provide a pressure-maintaining device, which aims to solve the technical problem that the pressure applied by the pressure-maintaining device is unstable, resulting in poor product assembly effect, unstable assembly effect and low yield.

[0006] To achieve the above objectives, the solution provided by this application is:

[0007] A pressure maintaining device includes:

[0008] A carrier, used to carry the product to be processed;

[0009] A driving assembly is spaced apart from the carrier;

[0010] A pressure-holding component, wherein the driving component is connected to the pressure-holding component to drive the pressure-holding component to move toward or away from the carrier, so that the pressure-holding component presses against or releases the product to be processed;

[0011] The pressure-maintaining component includes a detection component, an elastic component and a pressure-maintaining component, one end of the elastic component is connected to the detection component, and the other end of the elastic component is connected to the pressure-maintaining component;

[0012] The pressure-maintaining component is used to cause the elastic component connected to the pressure-maintaining component to undergo elastic deformation when pressing against the product to be processed;

[0013] The detection component is used to detect the force generated when the elastic component undergoes elastic deformation;

[0014] The digital display unit is electrically connected to the detection component and is used to display the pressure value borne by the elastic component.

[0015] The pressure maintaining device provided by this application has the following beneficial effects:

[0016] In the pressure-holding device of this embodiment, the drive assembly drives the pressure-holding assembly to move it toward or away from the carrier, causing it to press against or release the product to be processed. Within the pressure-holding assembly, the ends of an elastic component are connected to the detection component and the pressure-holding component, respectively. The elastic component is capable of elastic deformation under pressure, tends to return to its original shape when the pressure is reduced, and can also return to its original shape when the pressure is removed.

[0017] At the same time, the detection component is electrically connected to the digital display unit, so that the detection component can transmit the real-time detected pressurization pressure to the digital display unit in the form of a signal, and the digital display unit displays the pressure value currently detected by the detection component. Then, by comparing the current pressure value with the preset pressure value or pressure range, the operator can know whether the current pressure value is the preset pressure value or within the preset pressure range during the pressure holding process, and adjust the current pressure when the current pressure value is not the preset pressure value or is not within the preset pressure range, so that the current pressure value is stabilized at the preset pressure value or within the preset pressure range, thereby improving the assembly effect of two or more components, improving the stability of the assembly effect of two or more components, avoiding excessive pressure causing damage to the product, and avoiding insufficient pressure causing unstable connection between two or more components, thereby improving product yield.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0035] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0036] At present, before using the pressure-maintaining device to apply pressure to the product to be processed, the pressurization pressure will be detected by an external force measuring tool. In the process of using the external pressure measuring tool to detect the pressurization pressure, if the pressure value detected by the external force measuring tool is not the preset pressure value or is not within the preset pressure range, the operator will manually adjust the valve (such as the pressure regulating valve) connected to the pressure-maintaining device to increase or decrease the pressurization pressure, so that the pressurization pressure detected by the external tool is the preset pressure value or within the preset pressure range. At this time, the current pressure value measured by the external force measuring tool is defaulted to the actual pressure applied by the pressure-maintaining device during the pressurization process. It should be understood that the external force measuring tool is not part of the pressure-maintaining device. However, the pressure-maintaining device cannot detect the actual pressure applied by the pressure-maintaining device to the product to be processed in real time during the pressurization process, which can easily make the pressurization pressure too large or too small, the pressurization pressure unstable, resulting in poor pressurization effect, and affecting product quality.

[0037] like Figure 1 As shown, the embodiment of the present application provides a pressure-maintaining device 100 for maintaining pressure on a product to be processed 200. The pressure-maintaining device 100 includes a carrier 10, a drive assembly 20, a pressure-maintaining assembly 30, and a digital display unit 40. The carrier 10 is used to support the product to be processed 200, and the product to be processed 200 can be placed on the carrier 10. The drive assembly 20 is spaced apart from the carrier 10. The drive assembly 20 drives the pressure-maintaining assembly 30 to drive the pressure-maintaining assembly 30 to move toward or away from the carrier 10, so that the pressure-maintaining assembly 30 presses against or releases the product to be processed 200.

[0038] Further, such as Figure 2As shown, the pressure-holding component 30 includes a detection component 31, an elastic component 32 and a pressure-holding component 33. One end of the elastic component 32 is connected to the detection component 31, and the other end of the elastic component 32 is connected to the pressure-holding component 33. The pressure-holding component 33 is used to elastically deform the elastic component 32 connected to the pressure-holding component 33 when it is pressed against the product 200 to be processed. The detection component 31 is used to detect the force generated when the elastic component 32 is elastically deformed. The digital display unit 40 is electrically connected to the detection component 31 for displaying the pressure value to which the elastic component 32 is subjected.

[0039] In the pressure-maintaining assembly 30 of this embodiment, the two ends of the elastic component 32 are respectively connected to the detection component 31 and the pressure-maintaining component 33, and the elastic component 32 can undergo elastic deformation under the action of pressure, and has a tendency to return to its original shape when the pressure is reduced, and can return to its original shape when the pressure disappears.

[0040] At the same time, the detection component 31 is electrically connected to the digital display unit 40, so that the detection component 31 can transmit the real-time detected pressurization pressure to the digital display unit 40 in the form of a signal, and the digital display unit 40 displays the pressure value currently detected by the detection component 31. Then, by comparing the current pressure value with the preset pressure value or pressure range, the operator can know whether the current pressure value is the preset pressure value or within the preset pressure range during the pressurization process, and adjust the current pressure when the current pressure value is not the preset pressure value or is not within the preset pressure range, so that the current pressure value is stabilized at the preset pressure value or within the preset pressure range, thereby improving the assembly effect of two or more components in the product to be processed, improving the stability of the assembly effect, avoiding excessive pressure from damaging the product, and avoiding insufficient pressure from causing unstable connection between two or more components, thereby improving product yield.

[0041] Specifically, when the current pressure value or pressure interval P1 is greater than the preset pressure value or pressure interval P2, the operator manually or the pressure-maintaining device 100 automatically controls the driving component 20 according to a preset program to drive the pressure-maintaining component 30 to move upward a preset distance L1, thereby reducing the pressure on the elastic component 32, so that the elastic component 32 recovers part of its deformation, and thus achieves the stabilization of the current pressure (i.e., the pressure of the pressure-maintaining component 30 against the product to be processed 200) at the preset pressure value or pressure interval P2; similarly, when the current pressure value or pressure interval P1 is less than the preset pressure value or pressure interval P2, the operator manually or the pressure-maintaining device 100 automatically controls the driving component 20 according to a preset program to drive the pressure-maintaining component 30 to move downward a preset distance L2, thereby increasing the pressure on the elastic component 32 to increase the deformation of the elastic component 32, and thus achieves the stabilization of the current pressure at the preset pressure value or pressure interval P2.

[0042] Among them, when controlling the pressure change, the length L that the elastic component 32 needs to compress or restore the deformation is the correspondence between the elastic deformation and the pressure value measured based on the material or structural characteristics of the elastic component 32. The correspondence is a corresponding data table or function, and the corresponding data table or function is stored in the memory and can be read and executed by the processor.

[0043] Among them, the preset pressure value or pressure range can be set according to the actual product 200 to be processed. For example, a preset pressure value or pressure range is set for each batch of products, so that the pressure applied by the pressure maintaining component 30 to the product 200 to be processed can be adjusted according to different products 200 to be processed.

[0044] like Figure 3 As shown, in a specific embodiment, the product 200 to be processed includes a temple 201 and a speaker 202, the carrier 10 is provided with a groove 11 adapted for the temple 201, the groove 11 is used to place the temple 201, and a sound cavity 203 for accommodating the speaker 301 is provided in the temple 201, and the surrounding wall and / or bottom wall of the sound cavity 203 are coated or adhered with bonding glue. Under the action of the driving component 20, the pressure-maintaining component 33 presses the speaker 202 with a set pressure within a set preset time, thereby fixing the speaker 202 on the temple 201.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments, the driving assembly 20 includes a driving member 21 and a transmission member 22. The driving member 21 drives the transmission member 22 to drive the transmission member 22 to move. The pressure maintaining assembly 30 is connected to the transmission member 22 and moves with the transmission member 22.

[0046] In this embodiment, the driving member 21 is used to provide driving force to drive the transmission member 22 to move in the vertical direction, thereby driving the pressure-maintaining member 33 to press against the product to be processed on the carrier 10. For example, the transmission member 22 is a transmission plate, and the driving member 21 can be a cylinder. The pressure of the cylinder can be adjusted automatically, for example, by providing a controller (not shown) to automatically control a pressure regulating valve connected to the cylinder to control the air source pressure, thereby adjusting the cylinder pressure to a desired value.

[0047] like Figure 2 and Figure 3 As shown, further, the pressure-maintaining device 100 also includes a base 50 and a mounting plate 60. The mounting plate 60 is fixedly connected to the top of the base 50. The base 50 is used to place the carrier 10. The drive assembly 20 is installed on the mounting plate 60. The mounting plate 60 is also provided with a guide groove or guide rail in the horizontal direction. The drive assembly 20 is slidably connected to the guide groove or guide rail, so that the position of the drive assembly 20 in the horizontal direction can be adjusted as needed, thereby realizing pressing at multiple positions.

[0048] Furthermore, a plurality of limiting grooves or limiting protrusions are provided on the upper surface of the base 50, and a plurality of corresponding limiting protrusions or limiting grooves are provided on the bottom surface or side surface of the carrier 10 facing the base 50. The plurality of limiting grooves or limiting protrusions of the base 50 are plugged into the plurality of limiting protrusions or limiting grooves of the carrier 10 one by one, and the plurality of limiting grooves or limiting protrusions are arranged along the same or different directions; specifically, the plurality of limiting grooves or limiting protrusions are arranged in the two-dimensional plane where the surface of the base 50 is located or parallel to the two-dimensional plane where the surface of the base 50 is located, and the guiding direction of the plurality of limiting grooves or limiting protrusions is parallel to the connection direction between the mounting plate 60 and the base 50 or perpendicular to the connection direction between the mounting plate 60 and the base 50.

[0049] Further, such as Figure 3 As shown, the side surface of the mounting plate 60 is perpendicular to the upper surface of the base 50 , and a mounting seat 61 for mounting the driving member 21 is provided on the side surface of the mounting plate 60 .

[0050] like Figure 2 As shown, in some embodiments, the pressure-maintaining device 100 also includes a linear slide 70 and a sliding component 80. The linear slide 70 is installed on the mounting plate 60 and is perpendicular to the upper surface of the base 50. The transmission member 22 is slidably connected to the linear slide 70 through the sliding component 80, and drives the sliding component 80 to slide linearly on the linear slide 70 under the drive of the driving member 21, thereby driving the pressure-maintaining assembly 30 installed on the transmission member 22 to move in a straight line, and then can drive the pressure-maintaining component 33 to move in a straight line, so that the pressure-maintaining component 33 presses against the product to be processed 200 in a straight line direction.

[0051] like Figure 3 As shown, in some embodiments, the sliding component 80 includes a slider 81 and a slide plate 82. The slide plate 82 is slidably connected to the linear slide rail 70 through the slider 81. The transmission member 22 is vertically installed on the slide plate 82 to realize the connection between the transmission member 22 and the linear slide rail 70.

[0052] like Figure 2 As shown, in some embodiments, at least one pressure maintaining assembly 30 is provided, at least one pressure maintaining assembly 30 is connected to a side of the transmission member 22 facing away from the driving member 21 , and multiple pressure maintaining assemblies 30 are arranged at intervals.

[0053] like Figure 3 and Figure 4As shown, in some embodiments, the detection component 31 includes a pressure sensor 311 and a force transmission component 312. The force transmission component 312 is arranged between the pressure sensor 311 and the pressure maintaining component 33. The pressure sensor 311 is installed in the middle area of the side of the force transmission component 312 facing the driving assembly 20. One end of the elastic component 32 is connected to the pressure maintaining component 33, and the other end of the elastic component 32 is connected to the force transmission component 312. The pressure maintaining component 33 is used to move relative to the force transmission component 312 when it is pressed against the product to be processed 200, so as to press the elastic component 32 to cause the elastic component 32 to undergo elastic deformation. The pressure generated by the elastic deformation of the elastic component 32 can be transmitted to the force transmission component 312, so that the pressure sensor 311 can detect the force generated when the elastic component 32 undergoes elastic deformation through the force transmission component 312. The digital display unit 40 is electrically connected to the pressure sensor 311, and the pressure sensor 311 can output the pressure transmitted to the force transmission component 312 to the digital display unit 40 in the form of a signal.

[0054] like Figure 5 As shown, the force transmission member 312 is exemplarily a force transmission plate. Furthermore, the pressure sensor 311 is provided with a protruding sensing portion 313. A receiving hole 314 is provided in the center of the force transmission plate. The sensing portion 313 extends into the receiving hole 314 and contacts the inner wall of the receiving hole 314. The sensing portion 314 is used to sense the pressure transmitted to the force transmission member 312.

[0055] like Figure 3 and Figure 4 As shown, in some embodiments, the elastic component 32 includes a first connecting member 321 and an elastic member (not shown in the figure), the first connecting member 321 can be a pin, and the elastic member can be a spring, one end of the first connecting member 321 is fixedly connected to the pressure-holding member 33, and the other end of the first connecting member 321 is movably connected to the force transmission member 312; the elastic member is wrapped around the outer wall of the first connecting member 321, and one end of the elastic member is connected to the pressure-holding member 33, and the other end of the elastic member is connected to the force transmission member 312; the pressure-holding member 33 is used to drive the first connecting member 321 to move relative to the force transmission member 312 when it is pressed against the product to be processed 200, so as to press the elastic member to cause the elastic member to undergo elastic deformation.

[0056] In this embodiment, when the pressure-holding component 33 is pressed against the product to be processed 200, under the reaction force of the product to be processed 200, the pressure-holding component 33 can move relative to the force transmission component 312. During this process, the elastic component undergoes elastic deformation under the cooperative pressure of the pressure-holding component 33 and the force transmission component 312 to generate elastic force. Since the other end of the elastic component is connected to the force transmission component 312, the elastic force generated by the elastic component can be transmitted to the force transmission component 312.

[0057] like Figure 4 and Figure 5As shown, in some embodiments, there are two first connecting members 321 and two elastic members, with the two elastic members corresponding one to one with the two first connecting members 321. The two first connecting members 321 are symmetrically arranged around the pressure sensor 311, and thus the two elastic members are also symmetrically arranged around the pressure sensor 311. Consequently, when the two elastic members are compressed by the pressure-maintaining component 33, the portion of the force transmission member 312 located on one side of the pressure sensor 311 and the portion of the force transmission member 312 located on the other side of the pressure sensor 311 are both subjected to the same pressure, which facilitates uniform and stable force application to the force transmission member 312. More specifically, the two first connecting members 321 are symmetrically arranged around the sensing portion 313.

[0058] like Figure 3 and Figure 4 As shown, in some embodiments, the pressure-maintaining component 33 includes a mounting member 331 and a pressing member 332, the pressing member 332 is used to contact the product to be processed 200, the mounting member 331 and the force transmission member 312 are arranged at intervals, the end of the first connecting member 321 away from the force transmission member 312 is fixedly connected to the mounting member 331, the end of the elastic member away from the force transmission member 312 is connected to the mounting member 331, and the pressing member 332 is connected to the side of the mounting member 331 away from the force transmission member 312; the pressing member 332 is used to drive the mounting member 331 and the first connecting member 321 to move relative to the force transmission member 312 when it is pressed against the product to be processed 200, so as to compress the elastic member.

[0059] In this embodiment, when the pressing part 332 is pressed against the product to be processed 200, the product to be processed 200 applies a reaction force to the pressing part 332, so that the pressing part 332 drives the mounting part 331 and the first connecting part 321 to move toward the force transmission part 312 relative to the force transmission part 312, thereby compressing the elastic part, causing the elastic part to elastically deform and generate elastic force. The elastic force generated by the elastic deformation of the elastic part is transmitted to the force transmission part 312 and detected by the pressure sensor 311, thereby realizing real-time detection of the current pressure during the pressurization process.

[0060] Exemplarily, the mounting member 331 is plate-shaped, and the pressing member 332 can be a pressure-maintaining head. The pressing member 332 is adapted to the product to be processed 200. For example, when the product to be processed 200 includes temples 201 and speakers 202, the outer contour of the part of the pressing member 332 that contacts the speaker 202 is adapted to the outer contour of the speaker 202.

[0061] like Figure 3 and Figure 4As shown, in some embodiments, the pressure-maintaining component 33 also includes a second connecting member 333, which can be a movable pin. One end of the second connecting member 333 is fixedly connected to the mounting member 331, and the other end of the second connecting member 333 is movably connected to the force transmission member 312, so that when the pressing member 332 presses against the product 200 to be processed, the second connecting member 333 follows the mounting member 331 to move relative to the force transmission member 312.

[0062] like Figure 3 and Figure 4 As shown, in some embodiments, the number of the second connecting members 333 is two. In the length direction of the force transmission member 312, the two second connecting members 333 are respectively located on opposite sides of the pressure sensor 311, and the second connecting members 333 are along the moving direction of the transmission member 22 (such as Figure 3 The mounting member 331 and the pressing member 332 extend in a straight line along the moving direction of the transmission member 22, and can guide the mounting member 331 and the pressing member 332 to move in a straight line along the moving direction of the transmission member 22, such as guiding the mounting member 331 and the pressing member 332 to move in a straight line toward the force transmission member 312 along the moving direction of the transmission member 22, so as to ensure that the pressing member 332 compresses the elastic member in a straight line.

[0063] In this embodiment, in addition to the first connecting member 321 provided between the force transmission member 312 and the mounting member 331, a second connecting member 333 is further provided to improve the connection stability between the force transmission member 312 and the mounting member 331. Figure 5 As shown, the second connecting member 333 includes a cylinder 334 and a pin 335 passing through the cylinder 334. The cylinder 334 passes through the force transmission member 312 and is fixedly installed on the force transmission member 312. The pin 335 can move relative to the cylinder 334 under the drive of the mounting member 331.

[0064] Combine Figure 1 and Figure 2 In some embodiments, the pressure-maintaining device 100 further includes a controller (not shown) and a timing unit (not shown). The drive assembly 20, the detection component 31, the digital display unit 40, and the timing unit are electrically connected to the controller. The timing unit is used to set and calculate the pressurization time, and the digital display unit 40 is also used to display the pressurization time. The timing unit can be a timer, which includes a screen for displaying time and buttons located below the screen. The buttons include a first button for entering the pressurization time and a second button for starting the timer. The first button can be a numeric button.

[0065] In this embodiment, the detection component 31 can detect the elastic force generated by the elastic deformation of the elastic component 32, and send the measured current pressure value to the digital display unit 40, which is displayed in real time by the digital display unit 40. The operator can monitor the actual pressure by observing the pressure value displayed by the digital display unit 40, thereby facilitating the operator to monitor the pressurization status. The timing unit is used to set the pressurization time before the start of pressurization, and to calculate the pressurization time during the pressurization process, such as calculating the pressurization time in a countdown manner, so that the pressurization is stopped when the pressurization time reaches the set pressurization time. The entire pressurization process does not require manual calculation of the pressurization time, which improves the degree of automation and reduces the errors caused by manual operation. Moreover, the use of automated timing can achieve precise control of the pressurization time compared to manual timing, and also improves processing efficiency and processing quality. Among them, the set pressurization time can be a specific time set according to the actual product needs.

[0066] like Figure 2 As shown, in some embodiments, the digital display unit 40 is disposed on the front side of the base 50 , which is the side close to the operator, making it convenient for the operator to view the pressure data and / or time data displayed by the digital display unit 40 .

[0067] like Figure 2 As shown, in some embodiments, the digital display unit 40 includes a first display screen 41 and a second display screen 42 arranged side by side. The first display screen 41 is used to display the actual force value and the set pressure value, and the second display screen 42 is used to display the pressing time. In other embodiments, the digital display unit 40 includes a third display screen (not shown), which is used to display the pressure value measured by the detection component 31 and the pressing time. For example, the screen provided with the third display screen can display two rows of values, one row of which is the force value and the other row is the pressing time.

[0068] Combine Figure 2 Furthermore, an alarm mechanism (not shown) is provided on the front side of the base 50. The alarm mechanism is used to issue an audible and / or visual alarm when the actual pressure value during the pressurization process is not a preset pressure value or is not within a preset pressure range. In this case, the drive assembly 20 can be manually or through a controller to first stop driving the pressure-maintaining assembly 30, and then adjust the current pressure to stabilize the current pressure value at the preset pressure value or within the pressure range. Exemplarily, the alarm mechanism can be an indicator light and / or a buzzer to issue an audible and / or visual alarm to alert the operator when the current pressure is not within the preset pressure range during the pressurization process.

[0069] In combination with the above, in this embodiment, before the pressure-maintaining device 100 pressurizes the product 200 , the pressurizing pressure and the pressurizing time can be set by the timing unit.

[0070] Then, when the pressurization starts, the controller controls the driving component 20 to drive the pressure-holding component 30 to move toward the direction close to the product to be processed 200, so that the pressure-holding component 33 presses against the product to be processed 200, so that the pressure-holding component 33 applies continuous pressure to the product to be processed 200. During this process, the detection component 31 detects the current pressure in real time, and the timing unit calculates the pressurization time. In the process of the pressure-holding component 33 pressing against the product to be processed 200, the controller controls the driving component 20 according to the pressure value measured by the detection component 31, so as to control the driving component 20 to increase the current pressure, reduce the current pressure or keep the current pressure unchanged, so as to adjust the current pressure value to the preset pressure value or stabilize it within the preset pressure range.

[0071] Subsequently, after the pressurization reaches the set time, the pressurization is stopped. At this time, the controller can control the driving component 20 to drive the pressure holding component 30 to move away from the product to be processed 200, releasing the product to be processed 200. At the same time, the alarm mechanism can issue a sound prompt or a light prompt, such as emitting a green light, to prompt the operator that the pressurization is completed, so as to facilitate the next operation, such as taking out the product after pressurization. The entire pressurization process is automatically completed by the pressure holding device 100, which improves the degree of automation. In addition, compared with manual pressurization, the automatic completion of the pressurization operation can improve the pressurization accuracy and is also conducive to repeated pressurization operations. In this embodiment, during the pressurization process, if the current pressure value is not the preset pressure value or is not within the preset pressure range, the alarm mechanism can also issue a sound prompt or a light prompt, such as emitting a red light, to prompt the operator to pay attention to the current pressure.
