Description

Technical Field

[0001] The present application relates to the field of product manufacturing, and in particular to a fluid introduction device with a film peeling function, a film peeling method, and a fluid introduction method. Background Art

[0002] In the process of fluid introduction of the product, the fluid needs to be introduced into the internal space of the product to improve the impact resistance of the product. However, during the introduction process, the introduced fluid often has a certain viscosity. In order to improve the fluidity of the fluid, the gas in the internal space of the product is usually extracted through the exhaust device while the fluid is introduced to form a pressure difference inside the product. In this process, in order to prevent the fluid from entering the exhaust device during the exhaust, a film layer structure will be attached to the place where the exhaust device contacts the product. The film layer structure can both extract the gas and prevent the fluid from entering the exhaust device.

[0003] However, the film layer structure is currently attached and removed manually, with the film being attached first and then vacuumed. Fluid is introduced into the inner cavity of the product while vacuuming. After the fluid fills the inner cavity of the product, the film layer structure is manually removed. This undoubtedly increases the cost of the fluid introduction process. Furthermore, when the film is removed, the fluid adhering to the back of the film layer structure is easily brought to the surface of the product, contaminating the surface of the product and affecting subsequent processes.

[0058] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0059] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0060] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0062] Please refer to Figures 1 to 3 As shown, Figure 1 , Figure 2 Two three-dimensional structural schematic diagrams of the fluid introduction device 100 provided in the embodiment of the present application, Figure 3 FIG. 1 is a block diagram of a fluid introduction device 100 provided in an embodiment of the present application. Figure 4 The figure shows a side view of a fluid introduction device 100 provided in an embodiment of the present application. In addition to the function of introducing fluid into the cavity 203 of the product 200, the fluid introduction device 100 in this embodiment also has the function of removing the breathable membrane covering the exhaust hole 202 of the product 200 after the introduction is completed.

[0063] The product 200 includes an introduction hole 201, an exhaust hole 202 and a cavity 203, wherein the introduction hole 201 and the exhaust hole 202 are connected to the cavity 203, and the exhaust hole 202 is located on the surface of the product 200. Before the fluid is introduced into the product 200, it is placed at a preset position on the workbench 300. A fixing assembly 20 may be provided on the workbench 300 to fix the product 200, so as to keep the product 200 fixed at a specific position of the workbench 300 without moving during the fluid introduction process. It is understandable that the number of the introduction hole 201 and the exhaust hole 202 may correspond one to one, or may be one to many. For example, the product 200 is provided with an introduction hole 201 and an exhaust hole 202, or the product 200 is provided with an introduction hole 201 and two exhaust holes 202, or the product 200 is provided with two introduction holes 201 and one exhaust hole 202.

[0064] The fluid introduction device 100 includes a transfer mechanism 101 , an exhaust module 102 , a first pressure sensor 103 , a second pressure sensor 104 , a film supply module 105 , an introduction module 106 and a workbench 300 .

[0065] The introduction module 106 includes a guide nozzle 161, and the introduction module 106 is used to introduce fluid into the cavity 203 of the product 200 through the guide nozzle 161 and the introduction hole 201. In one embodiment, the guide nozzle 161 is an introduction needle, and in other embodiments, the guide nozzle can also be a catheter, etc. The introduction module 106 can also include a mixing tube (not shown in the figure) and a mixing valve 162 connected to the mixing tube. The mixing tube is used to mix different types of fluids and is connected to the introduction needle. The mixing valve 162 is used to control the opening and closing of the mixing tube. The introduction module 106 also includes a liquid outlet valve (not shown in the figure), which is connected to the introduction needle. The liquid outlet valve can be closed to control the introduction needle to discharge or stop the liquid. In one embodiment, the liquid outlet valve is a flow control valve, which can not only be used to control the outflow or stop the outflow of the introduction needle fluid, but also control the fluid introduction speed of the introduction needle.

[0066] In one embodiment, the introduction module 106 further includes a first driving member 163 and a delivery tube 164 connected to the guide nozzle. The delivery tube 164 has a delivery screw (not shown in the figure). The first driving member 163 is connected to the delivery screw to drive the delivery screw to rotate and drive the fluid in the delivery tube 164 to flow toward the guide nozzle. The first driving member 163 can be a motor. The rotation rate of the delivery screw can be controlled by controlling the rotation rate of the first driving member 163, thereby controlling the introduction rate of the introduced fluid into the cavity, so as to achieve controllable introduction speed during the entire fluid introduction process.

[0067] The suction module 102 includes a suction nozzle 12, which can be used in conjunction with a breathable membrane to press the breathable membrane against the exhaust hole 202 through the suction nozzle 12 and extract the gas in the cavity 203 through the exhaust hole 202, so that a certain negative pressure environment is formed in the cavity 203, which is conducive to draining the introduced fluid. The suction module 102 also includes a suction motor (not shown in the figure) connected to the suction nozzle 12 to generate power to extract the gas in the cavity of the product 200. The breathable membrane has a waterproof function. On the one hand, the suction nozzle 12 can extract the gas in the cavity 203 through the breathable membrane, and on the other hand, it can prevent the fluid in the cavity 203 from overflowing out of the exhaust hole 202.

[0068] In this embodiment, the transfer mechanism 101 is connected to the breathable film, and can move relative to the product 200 in a direction perpendicular to the surface of the product 200, so that the breathable film is separated from or pressed against the exhaust hole 202. On the one hand, before the air is pumped out, the transfer mechanism 101 drives the breathable film to move in the direction of the exhaust hole 202 on the surface of the product 200, so that the breathable film presses the exhaust hole 202 of the product. On the other hand, after the introduction is completed, the transfer mechanism 101 drives the breathable film to move in a direction away from the surface of the product 200, so as to uncover the breathable film. When the breathable film is separated from the exhaust hole 202, since the transfer mechanism 101 moves relative to the surface of the product 200 in a direction perpendicular to the surface of the product 200, the breathable film is effectively prevented from being stained with fluid and the probability of the fluid being brought to the surface of the product 200 and thus contaminating the product 200 is reduced. Even if the breathable film is stained with fluid, the fluid will fall into the exhaust hole 202 under the action of gravity, and will not overflow to the side to the surface of the product 200.

[0069] It should be noted that the surface of the above-mentioned product can be a plane or a curved surface. When the surface of the product is a plane, the transfer mechanism 101 moves in a direction perpendicular to the surface of the product; when the surface of the product is a curved surface, the transfer mechanism 101 moves in a direction perpendicular to the section where the curved surface is located.

[0070] It should be noted that the transfer mechanism 101 in this embodiment is connected to the breathable membrane, which means that the breathable membrane can move with the transfer mechanism 101, and the breathable membrane is stationary relative to the transfer mechanism 101 during operation. Specifically, when the transfer mechanism 101 moves toward the product 200, the breathable membrane also moves toward the product 200; when the transfer mechanism 101 moves away from the product 200, the breathable membrane also moves away from the product 200. That is, the breathable membrane can be hung on the transfer mechanism 101, or it can be located on a component of the transfer mechanism 101.

[0071] In another embodiment, the transfer mechanism 101 can also be used to drive the breathable membrane to move along a first direction so that the breathable membrane is separated from the exhaust hole, and the first direction is a direction that is consistent with or parallel to the axis of the suction nozzle. In addition, the transfer mechanism 101 can also be used to drive the breathable membrane to move along a second direction so that the breathable membrane is close to the exhaust hole, and the second direction is a direction that is consistent with or parallel to the axis of the suction nozzle, that is, the second direction is parallel to the first direction but opposite. Since the suction direction of the suction nozzle is along the direction of the axis of the suction nozzle, the suction nozzle fits the product. When the transfer mechanism 101 drives the breathable membrane to move along the first direction, it can also prevent the fluid from being taken out with the breathable membrane, thereby reducing the probability of contaminating the product 200.

[0072] In another embodiment, the transfer mechanism 101 is connected to the vacuum nozzle 12 and the breathable membrane. On the one hand, when the fluid introduction device starts to start, the transfer mechanism 101 moves toward the exhaust hole 202 of the product 200, and at this time drives the vacuum nozzle 12 and the breathable membrane to move toward the exhaust hole 202. The vacuum nozzle 12 presses the exhaust hole 202 while also pressing the breathable membrane, so that the breathable membrane is pressed onto the exhaust hole 202, that is, the breathable membrane is located between the exhaust hole 202 and the vacuum nozzle 12, so that no additional film sticking process is required; on the other hand, after the fluid introduction is completed, the transfer mechanism 101 moves in a direction away from the exhaust hole (that is, away from the product), so that the vacuum nozzle 12 leaves the exhaust hole and the breathable membrane is uncovered, so that the action of uncovering the breathable membrane is incorporated into the process of the vacuum nozzle 12 leaving the exhaust hole, and no additional film tearing process is required. Compared with the traditional film sticking and tearing process, the film sticking station and the film tearing station are omitted, the fluid introduction time is saved, and the fluid introduction efficiency and equipment utilization rate are improved.

[0073] In another embodiment, the transfer mechanism 101 is connected to the suction nozzle 12, the breathable membrane and the guide nozzle. On the one hand, when the fluid introduction device starts to start, the transfer mechanism 101 moves toward the exhaust hole 202 of the product 200, and at this time drives the suction nozzle 12 and the breathable membrane to move toward the exhaust hole 202, and at the same time drives the guide nozzle 161 to move toward the introduction hole 201. The suction nozzle 12 presses the exhaust hole 202 and the breathable membrane at the same time, and no additional film sticking process is required. That is, the transfer mechanism 101 completes three tasks when moving toward the product: the guide nozzle is moved to the introduction hole 201 to start introducing liquid into the cavity 203 of the product 200, the breathable membrane is attached to the exhaust hole 202, and the suction nozzle 12 covers the exhaust hole 202. The hole can thereby carry out air extraction through the breathable membrane and the exhaust hole 202; on the other hand, after the fluid introduction is completed, the transfer mechanism 101 moves in a direction away from the exhaust hole (that is, away from the product), so that the air suction nozzle 12 and the guide nozzle leave the product and the breathable membrane is peeled off, that is, the transfer mechanism 101 completes three tasks when moving away from the product: the guide nozzle 161 leaves the introduction hole 201, the breathable membrane is peeled off, and the air suction nozzle 12 leaves the exhaust hole 202, so that the action of peeling off the breathable membrane is incorporated into the process of the air suction nozzle 12 leaving, and no additional film tearing process is required. Compared with the traditional film sticking and tearing process, the film sticking station and the film tearing station are omitted, the fluid introduction time is saved, and the fluid introduction efficiency and equipment utilization are improved.

[0074] In this embodiment, the term "relative to" in "relative to the movement of the product" means that the product does not move, while the transfer mechanism 101 drives the breathable film to move. In another embodiment, the product may move while the transfer mechanism 101 does not move, and the breathable film may also be separated from the exhaust hole. In this other embodiment, the product 200 may also be located on a moving component, the transfer mechanism 101 remains stationary, and the moving component moves in a direction perpendicular to the surface of the product and away from the breathable film, so that the product is separated from the breathable film, and the breathable film may also be uncovered, so that no other film-tearing action is required before or after unloading the product.

[0075] In another embodiment, the transfer mechanism 101 includes a pressure head (not shown), which moves with the transfer mechanism 101 and is used to move relative to the product 200 in a direction perpendicular to the surface of the product 200, so that the pressure head presses the breathable membrane and covers the exhaust hole 202. The breathable membrane plays a role in allowing gas to pass but not allowing fluid to pass, so as to prevent the fluid from leaking from the exhaust hole 202. After the breathable membrane is pressed by the pressure head, the suction nozzle is set on the breathable membrane to complete the suction operation during the liquid introduction process.

[0076] In this embodiment, the transfer mechanism 101 includes a sliding mechanism 111 and a base frame 112. The base frame 112 is connected to the sliding mechanism 111. The sliding mechanism 111 is connected to the suction nozzle 12, and is used to drive the suction module 102 to move relative to the product 200 in a direction perpendicular to the surface of the product 200. The first pressure sensor 103, the film supply module 105 and the suction nozzle 12 are connected to the base frame 112, and the base frame 112 realizes the connection between the modules and drives the suction nozzle 12 and the breathable film to move.

[0077] The sliding mechanism 111 includes a sliding drive member (not shown) and a sliding frame 111a, the sliding frame 111a is connected to the driving end of the sliding drive member and is slidably connected to the sliding drive member, and the base frame 112 is connected to the sliding frame 111a. The base frame 112 is also connected to the suction nozzle 12 or the pressure head, and the sliding frame 111a is driven by the sliding drive member to drive the base frame 112 to move relative to the product 200 in a direction perpendicular to the surface of the product 200 (for example, close to the product or close to the product), so as to press the breathable film against the exhaust hole 202 or uncover the breathable film from the exhaust hole 202 through the suction module 102 or the pressure head. In this embodiment, the sliding drive member may include a motor and a screw rod, the motor drives the screw rod to rotate, and the sliding frame 111a is fixed on the screw rod. In other embodiments, the sliding drive member may be a rack transmission member, a cylinder transmission member, a belt transmission member, etc.

[0078] See also Figure 4 The vacuum nozzle 12 includes an air inlet, which is located at the bottom of the vacuum nozzle 12, that is, the part of the vacuum nozzle that contacts the external device or structure that needs to be exhausted (in this embodiment, the external structure that needs to be exhausted is the exhaust hole on the product), and the air inlet is connected to the pneumatic device, and is used to extract the gas in the cavity 203 through the exhaust hole 202 when the air inlet is pressed on the breathable membrane.

[0079] The suction nozzle 12 is cut in a direction perpendicular to the axis of the suction nozzle 12 (or the direction of air intake) to form a first cross section and a second cross section arranged in parallel, wherein the second cross section is located between the first cross section and the air inlet and the area of ​​the first cross section is greater than the area of ​​the second cross section, and the area of ​​the first cross section is greater than or equal to the area of ​​the exhaust hole, so that the periphery of the suction nozzle 12 is arranged from small to large from one end where the air inlet is located to the other end, so that when the suction nozzle 12 is pressing the breathable membrane, the part of the outer periphery of the suction nozzle 12 with a radius smaller than the exhaust hole 202 extends into the exhaust hole 202, thereby improving the sealing performance of the suction nozzle 12 when pressing the breathable membrane. It should be noted that the first cross section and the second cross section are virtual cross sections, which are introduced here to describe the structural shape of the suction nozzle 12.

[0080] In one embodiment, the suction nozzle 12 protrudes outward and has an arc-shaped structure, and the outer periphery of the suction nozzle 12 has a rounded arc surface structure. Due to the opening tolerance of the product 200 and other issues, when there is a slight deviation in the vertical direction between the suction nozzle 12 and the exhaust hole 202, when the suction nozzle 12 moves toward the exhaust hole 202 of the product 200, the protruding arc-shaped structure of the suction nozzle 12 slides along the inner wall of the exhaust hole 202, so that the suction nozzle 12 slides into the exhaust hole 202, reducing the difficulty and number of alignment of the suction nozzle 12, so that there is no need to equip other complex alignment mechanisms, effectively improving the accuracy and convenience of the breathable membrane sealing, and at the same time, the air inlet of the suction nozzle 12 is located in the exhaust hole 202, ensuring that the fluid will not overflow from the gap of the breathable membrane and the fluid will not exceed the surface of the product 200. In other embodiments, the suction nozzle protrudes outward and has a cone or elliptical arc surface.

[0081] In one embodiment, the vacuum nozzle 12 also includes an elastic portion (not shown), which surrounds the air inlet of the vacuum nozzle 12. When the elastic portion is close to the exhaust hole 202, it is used to make soft elastic contact with the exhaust hole 202. When the vacuum nozzle 12 moves toward the exhaust hole of the product along with the transfer mechanism 101, since the vacuum nozzle 12 has the elastic portion, the vacuum nozzle has space for deformation, which is more conducive to the alignment of the vacuum nozzle 12 and the exhaust hole, and is conducive to improving the tightness of the fit between the vacuum nozzle 12 and the exhaust hole. At the same time, it can also avoid hard contact between the vacuum nozzle 12 and the periphery of the exhaust hole 202, thereby damaging the product 200.

[0082] In one embodiment, a partial outer radius of the elastic portion is slightly larger than an inner diameter of the exhaust hole 202, so that when the elastic portion of the vacuum nozzle 12 moves into the exhaust hole 202, the elastic portion is squeezed against the wall of the exhaust hole 202 by the action of the transfer mechanism 101. Under the continuous action of the transfer mechanism 101, the elastic portion is elastically deformed and the elastic portion of the vacuum nozzle 12 is disposed in the exhaust hole 202. Then, the elastic portion is elastically deformed to hold the elastic portion in the exhaust hole 202, thereby increasing the sealing performance of the vacuum nozzle 12 in holding the breathable membrane, thereby preventing external gas from entering the cavity 203 of the product 200 and preventing the fluid in the cavity 203 from overflowing.

[0083] The first pressure sensor 103 is used to sense the pressure of the suction nozzle 12 pressing down the breathable membrane to generate a first pressure value, and the transfer mechanism 101 adjusts the position of the suction nozzle 12 based on the first pressure value. In one embodiment, the first pressure sensor 103 is provided with a preset threshold value, within which it can be considered that the suction nozzle 12 is already close to the exhaust hole, and the preset threshold value ranges from 0.8N (Newton, the same below) to 3N. When the value sensed by the first pressure sensor 103 is less than 0.8N, the transfer mechanism 101 continues to drive the suction nozzle 12 to move toward the exhaust hole 202 (continue to press down) until the first pressure value is between 0.8N and 3N. When the first pressure value sensed by the first pressure sensor 103 is greater than 0.4g, the transfer mechanism 101 drives the suction nozzle 12 to move away from the exhaust hole 202 (lift the suction nozzle) until the first pressure value is between 0.8N and 3N, so as to prevent excessive pressure from causing pressure damage to the product 200.

[0084] The second pressure sensor 104 includes a sensing connector (not shown in the figure), and the second pressure sensor 104 senses the pressure in the cavity 203 of the product 200 through the sensing connector to generate a second pressure value. In this embodiment, the second pressure sensor 104 is located near the suction nozzle 12 in the suction module 102, which can minimize the sensing error and make the sensed second pressure value closer to the actual pressure value in the cavity 203 of the product 200. The second pressure sensor 104 can be a digital sensor, which uses an electronic signal line instead of an air pipeline to sense the second pressure value, which can greatly improve the response speed and authenticity of the pressure signal. In other embodiments, the second pressure sensor 104 can also be a traditional air sleeve sensor. The frequency of sensing by the second pressure sensor 104 can be determined according to the specific situation, for example, once every 0.01 seconds.

[0085] In one embodiment, the first pressure sensor 103 and the second pressure sensor 104 can be integrated into a total pressure sensor, which includes two sensor heads, one sensor head is used to sense the pressure in the cavity 203 of the product 200; and the other sensor head is used to sense the pressure of the vacuum nozzle 12 pressing down on the breathable membrane.

[0086] The film supply module 105 is used to provide a material belt 153, and the breathable film is located on the material belt 153. The film supply module 105 includes a material tray carrier 151, a material roll 152, and at least one guide wheel 1121. The material tray carrier 151 and the material roll 152 are installed on the base frame 112. The material tray carrier 151 is used to carry the material belt 153, and the material roll 152 is used to drive the material tray carrier 151 to rotate, thereby driving the material belt 153 to rotate together. The guide wheel 1121 is used to guide the material belt 153 to guide the breathable film on the material belt 153 to the top of the exhaust hole of the product 200. In other embodiments, the positions of the material roll 152 and the material tray carrier 151 are interchangeable.

[0087] See also Figure 5 and Figure 6 , which are respectively a schematic diagram of the planar structure of the material strip 153 and a schematic diagram of the cross section of the material strip 153 along the VV direction. The material strip 153 includes a gas-permeable film 1531 and a base layer 1532 arranged in layers, and the gas-permeable film 1531 is combined on the base layer 1532. The base layer 1532 is provided with a plurality of first holes 1532a arranged at intervals (the first holes 1532a penetrate the base layer 1532), and the distance between two adjacent first holes 1532a is the same. The first holes 1532a expose the gas-permeable film 1531. When the suction nozzle 12 is pressed on the gas-permeable film 1531 on the exhaust hole 202, the gas in the cavity 203 is extracted from the exhaust hole 202 through the first holes 1532a and the gas-permeable film 1531. The material strip 153 is also provided with a plurality of second holes 153a arranged at intervals, and the distance between two adjacent first holes 153a is the same. The second holes 153a penetrate the breathable film 1531 and the base layer 1532, and are used to locate the position of the material strip 153 through the photoelectric sensor. The plurality of second holes 153a are arranged at intervals with the plurality of first holes 1532a, that is, two second holes 153a are respectively arranged on both sides of each first hole 1532a.

[0088] The film supply module 105 further includes a photoelectric sensor 154 , which is mounted on the base frame 112 and is used to sense the movement of the material strip by receiving the reflection value of light. Specifically, when the material belt 153 is moving, the photoelectric sensor 154 receives the reflection value of the light on the material belt 153. When the reflection value of the light received by the photoelectric sensor 154 comes from the first hole 1532a or other positions of the material belt 153, since the first hole 1532a is covered with the air-permeable film 1531 and other positions of the material belt 153 are not penetrated, the reflection value of the light received by the photoelectric sensor 154 is large, and the material belt 153 continues to rotate. When the second hole 153a is located at the sensing position of the photoelectric sensor 154, since the second hole 153a penetrates the material belt 153 and the second hole 153a is hollow, the reflection value of the light received by the photoelectric sensor 154 is small (or zero), and the material belt 153 stops moving, thereby ensuring that the air-permeable film 1531 on the first hole 1532a is located directly below the suction nozzle 12. That is, the present embodiment determines the position of the material belt by the reflection value of the light in the photoelectric sensor 154.

[0089] In another embodiment, only the first hole position 1532a may be provided on the material strip 153, and the first hole position 1532a may not only be used to expose the breathable membrane 1531 to be held by the suction nozzle 12, but also be used to locate the position of the material strip 153 by means of a photoelectric sensor (the reflection value of the photoelectric sensor at the first hole position of the material strip is inconsistent with the reflection value of other positions of the material strip). In one embodiment, the breathable membrane 1531 is made of an elastic material, and the suction nozzle 12 presses down the breathable membrane 1531 when exhausting air, and uses the elasticity of the breathable membrane 1531 to press the breathable membrane 1531 against the exhaust hole 202 and make the part of the breathable membrane 1531 located at the exhaust hole 202 protrude into the exhaust hole 202, thereby increasing the sealing performance of the breathable membrane 1531 and preventing fluid from overflowing.

[0090] In the present embodiment, the film supply module 105 is located on the transfer mechanism. After the fluid introduction is completed, the transfer mechanism 101 moves in the direction away from the exhaust hole (that is, away from the product), so that the vacuum nozzle 12 leaves the exhaust hole, thereby driving the film supply module 105 to move in the direction away from the exhaust hole to uncover the breathable film. That is, when the transfer mechanism 101 moves away from the product, the vacuum nozzle 12 is removed, and the breathable film is uncovered at the same time, so that the action of uncovering the breathable film is incorporated into the process of the vacuum nozzle 12 leaving the exhaust hole, and no additional film tearing process is required. Compared with the traditional film sticking and tearing process, the film sticking station and the film tearing station are omitted, the fluid introduction time is saved, and the fluid introduction efficiency and equipment utilization rate are improved.

[0091] In one embodiment, the fluid introduction device 100 also includes a display 100a to display the sensed values ​​on the display 100a. The display 100a can display the sensed values, the vacuum time and the number of products into which the fluid has been introduced in real time. The sensed values, such as the first pressure value of the first pressure sensor 103 and the second pressure value sensed by the second pressure sensor 104 and the light reflection value sensed by the photoelectric sensor 154, are convenient for monitoring the fluid introduction time or the pressure condition of the cavity 203 during the vacuum operation, the pressure condition of the air permeable membrane 1531 at the exhaust hole 202, and the position of the air permeable membrane 1531.

[0092] The workbench 300 is used to place the product 200 to be processed, so as to cooperate with the transfer mechanism 101, the exhaust module 102, the film supply module 105 and the introduction module 106 to implement fluid introduction and exhaust work on the product 200.

[0093] See also Figure 3 In addition to the above components, the fluid introduction device 100 also includes a controller 107, a memory 108, an I / O interface 109 and a communication bus 110. The controller 107 is coupled to the transfer mechanism 101, the air extraction module 102, the first pressure sensor 103, the second pressure sensor 104, the photoelectric sensor 154, the film supply module 105, the introduction module 106, the memory 108 and the I / O interface 109 through the communication bus 110.

[0094] In this embodiment, the controller 107 is coupled to the second pressure sensor 104, the introduction module 106 and the exhaust module 102. The second pressure sensor 104 senses the pressure in the cavity 203 of the product 200, generates a second pressure value of an electrical signal or a digital signal, and transmits the second pressure value to the controller 107 through the communication bus 110, so that the controller 107 controls the operation of the exhaust module 102 or the introduction module 106 according to the second pressure value in the cavity 203. For example, the controller 107 controls the exhaust module 102 to start or stop the exhaust operation according to at least one second pressure value; or the controller 107 controls the fluid to perform or stop the introduction operation according to at least one second pressure value.

[0095] In another embodiment, the second pressure sensor 104 is coupled to the air extraction module 102, and the air extraction module 102 further includes a second controller, the second pressure sensor 104 is coupled to the second controller, and the air extraction module 102 is used to control the gas to start or stop the air extraction operation according to at least one second pressure value. In another embodiment, the second pressure sensor 104 is coupled to the introduction module 106, and the introduction module 106 further includes a first controller, the second pressure sensor 104 is coupled to the first controller, and the introduction module 106 is used to control the fluid to perform the introduction operation or stop the introduction operation according to at least one second pressure value.

[0096] It should be noted that the first controller and the second controller can be independent control devices, or they can be parts of the controller 107 (integrated into the controller 107 together) to complete the control functions of different modules. In this embodiment, the controller 107 is coupled to the first pressure sensor 103. After the first pressure sensor 103 senses the pressure of the air suction nozzle 12 pressing down the breathable membrane 1531 and generates a first pressure value of an electrical signal or a digital signal, the first pressure value is transmitted to the controller 107 through the communication bus 110, so that the controller 107 adjusts the position of the transfer mechanism 101 according to the first pressure value. In this embodiment, the controller 107 is coupled to the photoelectric sensor 154. After the photoelectric sensor 154 receives the reflection value of light and generates the reflection value of an electrical signal or a digital signal, the reflection value is transmitted to the controller 107 through the communication bus 110, so that the controller 107 controls the rotation of the material belt 153 according to the reflection value of light received by the photoelectric sensor 154, so that the breathable membrane 1531 is located between the air suction nozzle 12 and the exhaust hole 202 in the vertical plane.

[0097] The controller 107 is coupled to the transfer mechanism 101, and controls the transfer mechanism 101 to move relative to the product 200 in a direction perpendicular to the surface of the product 200, so that the breathable membrane 1531 presses or detaches from the exhaust hole 202. In one embodiment, the controller 107 is coupled to the sliding drive member, and is used to drive the sliding drive member to drive the sliding frame 111a to slide, thereby driving the suction nozzle 12 connected to the sliding frame 111a to move toward the exhaust hole 202, so that the suction nozzle 12 presses the breathable membrane 1531 or the breathable membrane 1531 is detached from the exhaust hole 202. In another embodiment, the controller 107 is also used to control the elastic part of the suction nozzle 12 to be clamped in the exhaust hole 202. In another embodiment, the controller 107 is used to control the transfer mechanism 101 to move relative to the product 200 in a direction perpendicular to the surface of the product 200, so that the pressure head presses the breathable membrane 1531 and covers the exhaust hole 202.

[0098] In one embodiment, the controller 107 controls the suction nozzle 12 to press the breathable membrane 1531 and make the breathable membrane 1531 protrude into the exhaust hole 202 to increase the sealing performance of the breathable membrane.

[0099] The controller 107 is also coupled to the film supply module 105 and the photoelectric sensor 154. The controller 107 is also used to control the movement of the material belt 153 so that the breathable film 1531 on the material belt 153 is located between the suction nozzle 12 and the exhaust hole 202 in the vertical plane. Specifically, the controller 107 is coupled to the material roll 152, and controls the material roll 152 to drive the material tray carrier 151 to rotate according to the reflection value transmitted by the photoelectric sensor 154. When the photoelectric sensor 154 senses the second hole position 153a, it is assumed that the first hole position 1532a on the breathable film is just above the exhaust hole 202. At this time, the controller 107 controls the material roll 152 to stop, thereby stopping the rotation of the material belt 153, and controls the transfer mechanism 101 to move so that the suction nozzle 12 presses the breathable film 1531 on the exhaust hole 202.

[0100] The controller 107 can be a central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application. In this embodiment, the controller 107 and the memory 108 are integrated in a chip, and the controller 107 is coupled to the transfer mechanism 101, the exhaust module 102, the first pressure sensor 103, the second pressure sensor 104, the film supply module 105, the introduction module 106, the memory 108 and the I / O interface 109 through the communication bus 110. In other embodiments, the controller 107 can be an independent device from the memory 108, and the controller 107 can also be connected to the transfer mechanism 101, the vacuum module 102, the first pressure sensor 103, the second pressure sensor 104, the film supply module 105, the import module 106, the memory 108 and the I / O interface 109 through a wireless network, such as wireless LAN, Bluetooth, near field communication (NFC) and wireless fidelity (Wi-Fi), so as to complete information transmission and control of fluid introduction, vacuum process and film peeling process.

[0101] The memory 108 can be used to store preset information, pressure values ​​received by the controller 107, and process information generated by the controller 107 during the fluid introduction process of the product 200. The memory 108 can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory can be independent and connected to the processor through a communication bus. The memory can also be integrated with the processor. In this embodiment, the pressure value information stored in the memory includes the first preset threshold value of the first pressure sensor 103, the second preset threshold value of the second pressure sensor 104, and the memory is also used to store the third preset threshold value of the photoelectric sensor 154, etc. The I / O interface 109 is a human-computer interaction interface of the fluid introduction device 100, which is used to receive information input and display information, and it may include an input interface and an output interface. The input interface communicates with the controller 107 and can accept user input in a variety of ways. For example, the input interface can be a mouse, a keyboard, a touch screen device or a sensor device, etc. The output interface communicates with the controller 107 and can display information in a variety of ways. For example, the output interface can be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector, etc.

[0102] The communication bus 110 can form an information path for transmitting information between the controller 107 and the transfer mechanism 101 , the exhaust module 102 , the first pressure sensor 103 , the second pressure sensor 104 , the film supply module 105 and the introduction module 106 .

[0103] The embodiment of the present application also provides an air extraction device 300, such as Figure 7As shown, the air extraction device 300 is used to extract air from the product, and the product has a filler inside. The air extraction device is used in combination with a breathable membrane. The product has an exhaust hole, and the breathable membrane covers the exhaust hole. The air extraction device includes a transfer mechanism 301, an air extraction nozzle, and a controller 307. The transfer mechanism 301 is connected to the breathable membrane, and the air extraction nozzle is connected to the transfer mechanism 301. The air extraction nozzle is used to extract the gas in the cavity through the breathable membrane and the exhaust hole. The controller 307 is coupled to the transfer mechanism 301 and is used to control the transfer mechanism 301 to move relative to the product in a direction perpendicular to the surface of the product, so that the air extraction nozzle and the breathable membrane are separated from the exhaust hole.

[0104] In this embodiment, the suction nozzle protrudes outward and has an arc-shaped structure. Due to problems such as the opening tolerance of the product, when there is a slight deviation in the vertical direction between the suction nozzle and the exhaust hole, when the suction nozzle moves toward the exhaust hole of the product, the inclined surface of the arc-shaped structure protruding from the suction nozzle contacts the inner wall of the exhaust hole, and the suction nozzle slides into the exhaust hole along the extension direction of the inclined surface of the suction nozzle. The difficulty and frequency of the suction nozzle alignment are reduced, the accuracy and convenience of the breathable membrane sealing are effectively improved, and the sealing performance of the suction nozzle during suction is improved.

[0105] In this embodiment, the air extraction device 300 further includes a film supply module 305 for providing a material belt, on which the breathable film is located, and the film supply module 305 is coupled to a controller 307, which is used to control the movement of the material belt so that the breathable film is located between the air extraction nozzle and the exhaust hole. The structure of the film supply module 305 is the same as that described above and will not be described in detail herein.

[0106] In this embodiment, the vacuum device 300 also includes a vacuum module 302, which includes a vacuum nozzle. The vacuum module 302 is coupled to a controller 307 and is used to control the vacuum nozzle to move toward the exhaust hole so that the vacuum nozzle presses the breathable membrane, and the part of the breathable membrane located at the exhaust hole protrudes toward the exhaust hole, so that the breathable membrane completely covers the exhaust hole, thereby improving the sealing of the exhaust hole.

[0107] In this embodiment, the vacuum device 300 also includes a first pressure sensor 303. After the first pressure sensor 303 senses the pressure of the vacuum nozzle pressing down on the breathable membrane and generates a first pressure value of an electrical signal or a digital signal, the first pressure value is transmitted to the controller 307 through the communication bus 310, so that the controller 307 controls the position of the transfer mechanism 301 according to the first pressure value, and ensures the sealing of the breathable membrane covering the exhaust hole through the first pressure sensor 303.

[0108] It should be noted that, in this embodiment, the air extraction device 300 also includes a memory 308, a communication bus 310, and an I / O interface 309. For the connection relationship between the memory 308, the communication bus 310, and the I / O interface 309 and the controller 307, the air extraction module 302, etc., please refer to Figure 7 and in this manual Figure 3The structural diagram of the air extraction device 300 can be referred to Figure 1 and Figure 2 A schematic structural diagram of a fluid introduction device 100 .

[0109] In the present embodiment, the vacuum device 300 moves the transfer mechanism 301 in a direction perpendicular to the product surface to separate the vacuum nozzle and the breathable film from the exhaust hole. This can prevent the filler in the product cavity from contaminating the product surface. At the same time, since the breathable film is also peeled off when the vacuum nozzle leaves the exhaust hole, there is no need for an additional film sticking and tearing device, thereby improving the use efficiency of the vacuum device 300 and the utilization rate of the equipment.

[0110] In one embodiment, another air extraction device is disclosed, and the air extraction device can also be used in combination with a breathable sleeve, and the air extraction device includes a transfer mechanism, an air extraction nozzle, and a controller. The breathable sleeve is mounted on the air extraction nozzle, the air extraction nozzle protrudes outward and has an arc-shaped structure, the air extraction nozzle is connected to the transfer mechanism, the air extraction nozzle is used to extract the gas in the cavity through the breathable sleeve and the exhaust hole, and the controller is coupled to the transfer mechanism, and is used to control the transfer mechanism to move relative to the product in a direction perpendicular to the surface of the product, so that the air extraction nozzle and the breathable membrane sleeve are separated from the exhaust hole.

[0111] In one embodiment, another air extraction device is disclosed, which includes a transfer mechanism, an air extraction nozzle, and a controller. The air permeable sleeve is mounted on the air extraction nozzle, the air extraction nozzle protrudes outward and has an arc-shaped structure, and the air inlet of the air extraction nozzle includes an air permeable portion, the air permeable portion allows gas to pass through but does not allow fluid to pass through, the air extraction nozzle is connected to the transfer mechanism, the air extraction nozzle is used to extract gas in the cavity through the air permeable sleeve and the exhaust hole, and the controller is coupled to the transfer mechanism, and is used to control the transfer mechanism to move relative to the product in a direction perpendicular to the surface of the product, so that the air permeable portion of the air extraction nozzle is separated from the exhaust hole.

[0112] The embodiment of the present application further provides another fluid introduction device for introducing fluid into a cavity of a product, wherein the product further comprises an exhaust hole, wherein the exhaust hole is connected to the cavity, and the fluid introduction device further comprises:

[0113] A suction nozzle, used for extracting gas in the cavity through the exhaust hole;

[0114] A transfer mechanism, the vacuum suction nozzle is connected to the transfer mechanism, and the transfer mechanism is used to drive the vacuum suction nozzle to move toward the product so that the vacuum suction nozzle covers the exhaust hole;

[0115] The suction nozzle includes an air inlet and a first cross section and a second cross section that are parallel to each other, the second cross section is located between the first cross section and the air inlet, and the area of ​​the first cross section is greater than the area of ​​the second cross section. The area of ​​the first cross section is greater than or equal to the area of ​​the exhaust hole. It should be noted that the first cross section and the second cross section are virtual cross sections, which are introduced here to describe the structural shape of the suction nozzle.

[0116] In the fluid introduction device in this embodiment, since the second cross-section in the vacuum nozzle is located between the first cross-section and the air inlet, the area of ​​the first cross-section is larger than the area of ​​the second cross-section. Therefore, the outer periphery of the vacuum nozzle is arranged from small to large from one end where the air inlet is located to the other end. When the transfer mechanism drives the vacuum nozzle to move toward the exhaust hole of the product, the structure of the vacuum nozzle from small to large slides along the inner wall of the exhaust hole, so that the vacuum nozzle slides into the exhaust hole, reducing the difficulty and number of positioning the vacuum nozzle, and therefore there is no need to be equipped with other complex positioning mechanisms, which effectively improves the accuracy and convenience of the breathable membrane sealing. At the same time, the air inlet of the vacuum nozzle is located in the exhaust hole, ensuring that the fluid will not overflow from the gap in the breathable membrane and the fluid will not exceed the surface of the product.

[0117] In one embodiment, the vacuum nozzle in the fluid introduction device protrudes outward and has an arc-shaped structure. The vacuum nozzle includes an elastic portion, and the transfer mechanism is used to drive the vacuum nozzle to move toward the product to drive the elastic portion close to the exhaust hole. When the vacuum nozzle moves toward the exhaust hole of the product with the transfer mechanism, since the vacuum nozzle has an elastic portion, the vacuum nozzle has space to deform, which is more conducive to the alignment of the vacuum nozzle and the exhaust hole, and is conducive to improving the tightness of the vacuum nozzle and the exhaust hole. At the same time, it can also avoid the vacuum nozzle from hard contact with the periphery of the exhaust hole, thereby damaging the product.

[0118] In one embodiment, the suction nozzle is used in combination with a breathable membrane, and the suction nozzle is used to press the breathable membrane so that the portion of the breathable membrane located at the exhaust hole protrudes toward the exhaust hole.

[0119] The embodiment of the present application also provides a film peeling method for a fluid introduction device, which can be implemented in a fluid introduction device 100. The fluid introduction device 100 incorporates the film peeling method into the entire fluid introduction workflow. The following will focus on the film peeling method. For the sake of simplicity, please refer to the related description of the aforementioned fluid introduction device 100.

[0120] like Figure 8 As shown, it is a schematic flow chart of a film peeling method for a fluid introduction device provided in an embodiment of the present application, and the film peeling method comprises:

[0121] Step S01: providing a film supply module, wherein the film supply module is used to provide a material strip, and the breathable film is located on the material strip.

[0122] In this embodiment, the material strip includes a breathable film and a base layer arranged in a stacked manner, and the breathable film is combined with the base layer. The base layer is provided with a plurality of first holes arranged at intervals (the first holes penetrate the base layer), and the distance between two adjacent first holes is the same, and the first holes expose the breathable film. The material strip is also provided with a plurality of second holes arranged at intervals, and the distance between two adjacent first holes is the same, and the second holes penetrate the breathable film and the base layer, and are used to locate the position of the material strip through a photoelectric sensor. The plurality of second holes are arranged at intervals with the plurality of first holes, that is, two second holes are arranged on both sides of each first hole.

[0123] Step S02: providing a transfer mechanism, the breathable membrane being connected to the transfer mechanism, and the breathable membrane being used to cover the exhaust hole;

[0124] Step S03: Provide an exhaust module, the exhaust module includes an exhaust nozzle, the exhaust nozzle is connected to the transfer mechanism, the exhaust nozzle is used to extract the gas in the cavity from the exhaust hole through the breathable film; in this embodiment, the breathable film drives the exhaust nozzle to move through the transfer mechanism so that the exhaust nozzle presses the breathable film on the exhaust hole, so no additional film sticking equipment is required, and the breathable film is attached to the exhaust hole when the exhaust nozzle contacts the exhaust hole. In other embodiments, the breathable film can be manually attached to the exhaust hole, and the breathable film can also be located on a material belt, which is located on a film supply module, and the breathable film is covered on the exhaust hole through the transmission of the material belt and the pressure of a pressure head.

[0125] Step S04: Control the transfer mechanism to drive the vacuum nozzle and the breathable membrane to move relative to the product in a direction perpendicular to the surface of the product, so that the breathable membrane is separated from the exhaust hole.

[0126] In this embodiment, when the suction nozzle is pressed on the air-permeable membrane on the exhaust hole, the gas in the cavity is extracted from the exhaust hole through the first hole position and the air-permeable membrane.

[0127] In this embodiment, the surface of the above-mentioned product can be a plane or a curved surface. When the surface of the product is a plane, the transfer mechanism 101 moves in a direction perpendicular to the surface of the product; when the surface of the product is a curved surface, the transfer mechanism 101 moves in a direction perpendicular to the section where the curved surface is located.

[0128] In this embodiment, the transfer mechanism moves in a direction perpendicular to the surface of the product so that the breathable membrane is separated from the exhaust hole. It can also be understood that the transfer mechanism drives the breathable membrane to move in a first direction so that the breathable membrane is separated from the exhaust hole. The first direction is a direction consistent with or parallel to the axis of the suction nozzle. In addition, the transfer mechanism can also be used to drive the breathable membrane to move in a second direction so that the breathable membrane is close to the exhaust hole (when starting to pump air). The second direction is a direction consistent with or parallel to the axis of the suction nozzle, that is, the second direction is parallel to the first direction but opposite. Since the suction direction of the suction nozzle is along the direction of the axis of the suction nozzle, the suction nozzle fits the product. When the transfer mechanism drives the breathable membrane to move in the first direction, it can also prevent the fluid from being brought out with the breathable membrane, thereby reducing the probability of contaminating the product.

[0129] In this embodiment, the word "relatively" in "relative to the movement of the product" means that the product does not move, while the transfer mechanism drives the breathable film to move. In another embodiment, the product can move while the transfer mechanism does not move, and the breathable film can also be separated from the exhaust hole. In this other embodiment, the product can also be located on a moving component, the transfer mechanism remains stationary, and the moving component moves in a direction perpendicular to the surface of the product and away from the breathable film, so that the product can be separated from the breathable film, and the breathable film can also be uncovered, so that no other film tearing action is required when unloading the product.

[0130] In this embodiment, after the transfer mechanism drives the suction nozzle and the breathable membrane to move so that the breathable membrane is separated from the exhaust hole, the suction nozzle can be controlled to move away from the breathable membrane again. That is, the separation of the suction nozzle and the breathable membrane occurs after leaving the exhaust hole, not when attached to the exhaust hole. This method can prevent the breathable membrane from shaking when the suction nozzle leaves the breathable membrane, which is not conducive to the uncovering of the breathable membrane.

[0131] Step S05: solidifying the fluid in the product.

[0132] It should be noted that step S05 is performed after step S04, that is, the action of the air-permeable membrane being separated from the exhaust hole occurs before the fluid solidifies.

[0133] The above-mentioned film peeling method can effectively prevent the breathable film from being stained with fluid by peeling the breathable film in a direction perpendicular to the surface of the product. Even if the breathable film is stained with fluid, the fluid will fall into the exhaust hole under the action of gravity and will not overflow to the side of the product surface. Therefore, it can effectively prevent the fluid from contaminating the surface of the product when the breathable film is peeled off. The breathable film is peeled off while removing the suction nozzle. The existing equipment is used to incorporate the film peeling action into the existing fluid introduction process. That is, when the suction nozzle leaves the exhaust hole, the breathable film is also peeled off. There is no redundant time. While improving the degree of automation, the efficiency of fluid introduction and the utilization rate of equipment are also greatly improved.

[0134] like Fig. 9As shown, it is a schematic flow chart of a fluid introduction method provided by an embodiment. The fluid introduction method comprises the following steps:

[0135] Step S11: providing a fluid introduction device, the fluid introduction device comprising an introduction module, an exhaust module, a transfer mechanism and a controller, the controller being coupled to the introduction module, the transfer mechanism, the exhaust module and the film supply module,

[0136] In this embodiment, the film supply module is used to provide a breathable film, the exhaust module includes an exhaust nozzle, and the exhaust nozzle and the breathable film are connected to the transfer mechanism. The film supply module includes a material belt, the breathable film is located on the material belt, the material belt includes a breathable film and a base layer, the breathable film is combined with the base layer, the base layer has a plurality of first holes, and the first holes expose the breathable film.

[0137] Step S12: controlling the material belt to move so that the breathable membrane is located between the suction nozzle and the exhaust hole;

[0138] Step S13: Control the transfer mechanism to move toward the exhaust hole so that the suction nozzle presses the exhaust hole through the breathable membrane;

[0139] In this embodiment, the suction nozzle is configured to protrude outward and have an arc-shaped structure, so that when the suction nozzle presses the breathable membrane, the portion of the breathable membrane located at the exhaust hole is pressed into the exhaust hole, that is, the portion of the breathable membrane located at the exhaust hole protrudes toward the exhaust hole, ensuring that the breathable membrane presses the exhaust hole and improving the sealing. This step enables the suction nozzle to cover the exhaust hole when the transfer mechanism moves toward the exhaust hole, and the suction nozzle also presses the breathable membrane on the exhaust hole, thereby improving the fluid introduction efficiency and equipment utilization.

[0140] In one embodiment, the introduction module includes a guide nozzle, which is used to introduce fluid into the cavity through the introduction hole. The guide nozzle is connected to the transfer mechanism, and while the transfer mechanism is controlled to move toward the exhaust hole, the guide nozzle also moves toward the introduction hole, so that when the transfer mechanism moves toward the exhaust hole, the vacuum nozzle covers the exhaust hole, the vacuum nozzle also presses the breathable membrane onto the exhaust hole, and the guide nozzle also covers the introduction hole.

[0141] Step S14: sensing the pressure value of the suction nozzle pressing the exhaust hole by the first pressure sensor to generate a corresponding first pressure value;

[0142] The pressure value of the suction nozzle pressing the exhaust hole is sensed to generate a pressure value in the form of an electrical signal or a digital signal and transmit the pressure value to the controller through the communication bus. The controller receives the first pressure value from the first pressure sensor through the communication bus.

[0143] Step S15: determining whether the first pressure value reaches a first preset threshold value, if yes, proceeding to step S16, if no, returning to step S13;

[0144] The first preset threshold is stored in the memory, and the controller receives the first pressure value from the first pressure sensor and retrieves the preset threshold in the memory to determine whether the first pressure value meets the first preset threshold. In one embodiment, the first preset threshold ranges from 0.8N to 3N.

[0145] In other embodiments, if the first pressure value exceeds the preset threshold, the transfer mechanism is controlled to move slightly away from the exhaust hole to keep the first pressure value within the first preset threshold range as much as possible to avoid damage to the product due to excessive first pressure value.

[0146] Step S16: based on the first pressure value reaching the first preset threshold value, controlling the air extraction module to extract the gas in the cavity through the air extraction module through the exhaust hole;

[0147] After the air is pumped out by the vacuum module, the gas in the cavity is reduced, and a certain negative pressure environment is formed relative to the outside of the cavity.

[0148] Step S17: sensing the pressure inside the cavity by a second pressure sensor to generate a corresponding second pressure value;

[0149] The second pressure sensor senses the pressure in the cavity, generates a second pressure value in the form of an electrical signal or a digital signal, and transmits the second pressure value to the controller via the communication bus. The controller receives the second pressure value from the second pressure sensor via the communication bus. In this step, step S16 continues, that is, the second pressure value is sensed while the air is pumped out.

[0150] Step S18: determining whether the second pressure value reaches a second preset threshold value, if yes, proceeding to step S19, if no, returning to step S17;

[0151] The second preset threshold is stored in the memory. The controller receives the second pressure value transmitted by the second pressure sensor, retrieves the second preset threshold in the memory and compares the second pressure value transmitted by the second pressure sensor with the second preset threshold to determine whether the pressure value meets the second preset threshold.

[0152] Step S19: Based on the second pressure value transmitted by the second pressure sensor meeting the second preset threshold, the controller controls the introduction module to contact the introduction hole and introduce the fluid into the cavity;

[0153] In one embodiment, the controller controls the transfer mechanism to move toward the exhaust hole relative to the product, so that the guide nozzle contacts the introduction hole, and the vacuum nozzle presses the exhaust hole through the breathable membrane. When the vacuum nozzle presses the exhaust hole through the breathable membrane, the guide nozzle is also driven to contact the introduction hole, so that after the pressure sensed by the first pressure sensor and the second pressure sensor meets the preset threshold, the fluid can be directly introduced into the cavity to speed up the introduction rhythm.

[0154] Step S20: moving the transfer mechanism in a direction vertically away from the exhaust hole so that the suction nozzle and the breathable membrane are separated from the exhaust hole, and the guide nozzle is separated from the introduction hole;

[0155] After the fluid is introduced, in order to avoid the fluid from sticking to the breathable membrane after solidification, so that the breathable membrane cannot be removed, the fluid is not solidified before the breathable membrane is separated from the exhaust hole, so as to facilitate the opening of the breathable membrane. The present application effectively prevents the breathable membrane from being stained with fluid by moving the transfer mechanism in a direction vertically and away from the exhaust hole. Even if the fluid is stained, the fluid will fall into the exhaust hole under the action of gravity and will not overflow to the surface of the product to the side. Therefore, it can effectively avoid the fluid from contaminating the surface of the product when the breathable membrane is opened. It can be understood that when the introduction module is introducing the fluid, the second pressure sensor is also continuously sensing the pressure in the cavity and producing a corresponding second pressure value. The controller determines whether the second pressure value at this time meets the second preset threshold. The second preset threshold is the pressure value corresponding to the completion of the fluid introduction. When the second pressure value sensed by the second pressure sensor meets the second preset threshold, the controller controls the introduction module to stop introducing the fluid into the cavity.

[0156] In one embodiment, the fluid introduction method further comprises curing the product, and after the guide nozzle is separated from the introduction hole and the vacuum suction nozzle and the breathable membrane are separated from the exhaust hole, the product is heated and cured.

[0157] In one embodiment, the fluid introduction method is used to introduce a fluid into a plurality of products, and the fluid introduction method further comprises:

[0158] Step S21: Control the material belt to move a preset distance so that the next first hole position is located between the vacuum nozzle and the exhaust hole of the next product.

[0159] This step allows fluid introduction to the next product.

[0160] In this step, the material belt in the film supply module is controlled to move, and the reflection value of the light passing through the material belt is sensed by the photoelectric sensor, and a corresponding reflection value is generated; the photoelectric sensor senses the reflection value of the light passing through the material belt, generates the reflection value of the electrical signal or digital signal, and transmits the reflection value to the controller through the communication bus, and the controller receives the reflection value from the photoelectric sensor through the communication bus. The preset threshold of the reflection value (hereinafter referred to as the third preset threshold) is stored in the memory, the controller receives the reflection value transmitted by the photoelectric sensor, and calls the third preset threshold in the memory, and the controller compares the transmitted reflection value with the third preset threshold to determine whether the reflection value meets the third preset threshold. If yes, the film supply module is controlled by the controller to stop moving, so that the next breathable film on the material belt is located between the suction nozzle and the exhaust hole of the next product. If not, the controller continues to control the movement of the material belt until the reflection value measured by the photoelectric sensor meets the third preset threshold.

[0161] In the fluid introduction method provided in this embodiment, the existing equipment is used to incorporate the actions of film sticking and film peeling into the existing fluid introduction process, that is, when the vacuum suction nozzle is loaded, the breathable film is also stuck to the exhaust hole; when the vacuum suction nozzle is moved away from the exhaust hole, the breathable film is also peeled off, without redundant time, and while the degree of automation is improved, the efficiency of fluid introduction and the utilization rate of equipment are also greatly improved.

[0162] In another embodiment, a fluid introduction method is used to introduce a fluid into a plurality of products, and the fluid introduction method further comprises:

[0163] The controller controls the material belt to move a preset distance, and then the photoelectric sensor senses the reflection value of the light at the corresponding material belt position at this time, and compares it with the preset threshold of the reflection value. When the reflection value meets the preset threshold, it means that the next breathable membrane on the material belt has been moved between the vacuum nozzle and the exhaust hole of the next product. If it does not meet the preset threshold, an alarm will be issued, which may mean that the breathable membrane has not been accurately moved between the vacuum nozzle and the exhaust hole of the next product and needs to be checked.

[0164] In another embodiment, a fluid introduction method is used to introduce a fluid into a plurality of products, and the fluid introduction method further comprises:

[0165] The controller controls the material belt to move a preset distance, and then the photoelectric sensor senses the reflection value of the light at the corresponding material belt position at this time, and compares it with the preset threshold of the reflection value. When the reflection value meets the preset threshold, it means that the next breathable membrane on the material belt has been moved between the vacuum nozzle and the exhaust hole of the next product. If it does not meet the preset threshold, the controller controls the material belt to move another preset distance, and then the photoelectric sensor senses the reflection value of the light at the corresponding material belt position at this time, and compares it with the preset threshold of the reflection value. If the reflection value still does not meet the preset threshold, an alarm is issued, which may indicate that the breathable membrane has not been accurately moved between the vacuum nozzle and the exhaust hole of the next product and needs to be checked.
