[0029] See Figure 1 This utility model provides a foaming monitoring method, which can be applied to a foaming monitoring system to monitor the first weight information of the box to be foamed before foaming and the second weight information after foaming, and to confirm whether the box to be foamed is qualified based on the first weight information and the second weight information. The foaming monitoring method includes S110-S120.

[0030] S110, controlled by a foaming command to foam the box, obtains the first weight information of the box to be foamed before foaming, and obtains the second weight information of the box to be foamed after foaming.

[0031] In this embodiment of the invention, foaming is an important process. In the refrigerator manufacturing process, foaming refers to injecting foaming materials (such as polyurethane foam or polystyrene foam) into the refrigerator door or cabinet through specific process conditions and equipment, causing a chemical reaction to form a foam layer. This foam layer can be used for thermal insulation, load-bearing support, and moisture and toxicity prevention. Thermal insulation means that the foam layer has good thermal insulation properties, effectively reducing temperature loss inside the refrigerator, maintaining a low temperature inside, thereby extending refrigeration time and reducing energy consumption. Load-bearing support means that the foam layer can effectively support and bear the weight of the refrigerator, ensuring structural stability. Moisture and mold prevention means that the foam layer also has certain moisture and mold prevention properties, effectively preventing dampness and mold growth inside the refrigerator, keeping the interior clean and hygienic.

[0032] When an instruction to foam the refrigerator cabinet is received, the cabinet to be foamed is retrieved. Here, "cabinet" refers to the refrigerator's main body, and "cabinet to be foamed" refers to the individual parts of the main body that require foaming. Refrigerator production is often done on an assembly line. In the production stage before foaming, the cabinets to be foamed can be sent to a foaming monitoring system, which can monitor the foaming process and results simultaneously.

[0033] The foaming monitoring system can include components for acquiring the weight information of the box to be foamed. For example, a weighing component can be included to measure the weight of the box. When weighing the box, it can be weighed when it enters the foaming monitoring system, obtaining the first weight information. After foaming is complete, the box can be weighed again to obtain the second weight information. Therefore, the first weight information refers to the weight of the box before foaming, and the second weight information refers to the weight of the box after foaming is complete.

[0034] It is understandable that the weighing component can be a load cell. After weighing the weight of the foaming chamber, the load cell sends the weight information to the monitoring device so that the monitoring device can obtain the weight information.

[0035] S120, Based on the first weight information and the second weight information, confirm whether the foaming box is qualified.

[0036] In this embodiment of the utility model, the first weight information refers to the weight of the box to be foamed before foaming, and the second weight information refers to the weight of the box to be foamed after foaming. After obtaining the first weight information and the second weight information, the amount of foaming of the box to be foamed can be calculated based on the first weight information and the second weight information, and the quality of the box to be foamed can be confirmed based on the amount of foaming.

[0037] During the foaming process, black and white components, along with a foaming agent, are typically injected into the box to form a foam layer, thus completing the foaming. The type of box to be foamed affects the ratio, pressure, and flow rate of the black and white components; therefore, the appropriate foaming parameters need to be determined based on the specific type of box. Different foaming parameters result in different foaming volumes, which can be confirmed using first and second weight information.

[0038] See Figure 2 In some embodiments, such as in this embodiment, step S120 may include steps S121-S122.

[0039] S121, if the difference between the first weight information and the second weight information is within a preset qualified range, then the foaming box to be foamed is confirmed to be qualified;

[0040] S122, if the difference between the first weight information and the second weight information is outside the preset acceptable range, then the foaming box to be foamed is confirmed to be unqualified, and an early warning message is generated.

[0041] In this embodiment of the utility model, the quality of the foaming box can be confirmed by the foaming amount. For example, after obtaining the first weight information and the second weight information of the foaming box, the foaming amount can be obtained by calculating the difference between the first weight information and the second weight information.

[0042] For example, if the first weight information is Akg and the second weight information is Bkg, then subtracting Akg from Bkg yields Ckg, where A, B, and C are all positive numbers. Ckg can then be used to determine whether the foaming chamber is qualified. If Ckg is within the preset acceptable range, it indicates that the foaming chamber has passed this stage and can proceed to the next stage. If Ckg is outside the preset acceptable range, it indicates that the foaming chamber has failed this stage, and a warning message can be generated. The warning message can include the foaming parameters of the foaming chamber during this stage, such as the ratio of black and white materials, the pressure of black and white materials, and the flow rate of black and white materials, facilitating user analysis of the reasons for foaming failure. It can be understood that the preset acceptable range is a numerical interval; when Ckg is within the numerical interval, it indicates that the foaming chamber is qualified; when Ckg falls outside the numerical interval, it indicates that the foaming chamber is unqualified.

[0043] See Figure 3 In some embodiments, such as this embodiment, the method further includes steps S130-S160.

[0044] S130, obtain the configuration information of the foaming box to be foamed, and obtain the workstation information of the current workstation of the foaming box to be foamed;

[0045] S140, confirm whether the workstation information matches the configuration information;

[0046] S150, if the workstation information matches the configuration information, then the foaming of the box to be foamed is performed based on the configuration information;

[0047] S160, if the workstation information does not match the configuration information, an early warning message is generated.

[0048] In this embodiment of the invention, multiple workstations are typically set up to foam the boxes to be foamed. Different workstations are equipped with different molds to match different types of boxes to be foamed. When the box to be foamed enters the foaming monitoring system, its configuration information is acquired. This configuration information can be obtained through an identification component, which then sends it to the monitoring device. The configuration information may include product information about the box to be foamed, including the box model number. The box model number indicates the type of box to be foamed, facilitating the identification of the appropriate workstation for the box.

[0049] Once the workstation for the foam-to-be-foamed box is confirmed, the box is transported to the corresponding workstation. After the box arrives at the workstation, the workstation information is acquired. The workstation information is then verified to ensure it matches the configuration information. If the information matches, foaming can begin. If the information does not match, a warning is generated to alert the user of the mismatch between the current workstation and the box, requiring mold replacement.

[0050] For example, if the type of the foam box to be foamed is A, and there are currently three workstations: A1, A2, and A3, if the workstation matching the foam box is A1, and the foam box also enters workstation A1, then the configuration information of the foam box matches the workstation information, and foaming can proceed. However, if the type of the foam box matches workstation A1, but due to a fault or other reason the foam box enters workstation A2, then the obtained workstation information does not match the configuration information of the foam box, and a warning message can be generated.

[0051] See Figure 4 In some embodiments, such as this embodiment, the method further includes steps S170-S180.

[0052] S170, based on the configuration information, obtain the preset foaming parameters that match the box to be foamed, and obtain the real-time foaming parameters of the box to be foamed during foaming.

[0053] S180, confirm whether the real-time foaming parameters are qualified according to the preset foaming parameters.

[0054] In this embodiment of the invention, different types of foam-to-be-foamed boxes correspond to different preset foaming parameters. That is, different configuration information corresponds to different preset foaming parameters. Once the configuration information of the foam-to-be-foamed box is confirmed, the preset foaming parameters that match the configuration information can be confirmed. For example, multiple preset foaming parameters can be stored in advance, and different preset foaming parameters correspond to different configuration information. Therefore, once the configuration information is confirmed, the corresponding preset foaming parameters can be confirmed.

[0055] After obtaining the preset foaming parameters, the real-time foaming parameters can be obtained. The real-time foaming parameters refer to the parameters actually used during foaming, namely the actual ratio of black and white materials, the actual pressure of black and white materials, and the actual flow rate of black and white materials. The preset foaming parameters include the preset ratio of black and white materials, the preset pressure of black and white materials, and the preset flow rate of black and white materials. The consistency between the preset foaming parameters and the real-time foaming parameters is used to confirm whether the foaming chamber is qualified.

[0056] See Figure 5 In some embodiments, such as in this embodiment, step S180 may include steps S181-S182.

[0057] S181, if the difference between the real-time foaming parameter and the preset foaming parameter is within the range of the preset foaming threshold, then the real-time foaming parameter is confirmed to be qualified.

[0058] S182, if the difference between the real-time foaming parameter and the preset foaming parameter is outside the range of the preset foaming threshold, then the real-time foaming parameter is confirmed to be unqualified, and an early warning message is generated.

[0059] In this embodiment of the utility model, the preset foaming threshold is a numerical range, which can be an empirical value. After obtaining the real-time foaming parameters and the preset foaming parameters, the difference between the real-time foaming parameters and the preset foaming parameters is calculated. When the difference is within the preset foaming threshold, it indicates that the foaming is qualified. When the difference is outside the preset foaming threshold, it indicates that the foaming is unqualified, and a warning message can be generated.

[0060] See Figure 6 and Figure 7This utility model also provides a foaming monitoring system, which includes a conveying device 10, a filling device 20, and a monitoring device 30. The conveying device 10 includes a weighing component 11 and at least one preset station 12, and one preset station 12 corresponds to one box to be foamed. The weighing component 11 is used to acquire first weight information of each box to be foamed before foaming and second weight information of each box to be foamed after foaming. The filling device 20 is located on one side of the preset station 12 and is used to foam the box to be foamed located in the preset station 12. The monitoring device 30 is used to confirm whether the box to be foamed is qualified based on the first weight information and the second weight information.

[0061] Specifically, the foaming monitoring system includes a conveying device 10, an injection device 20, and a monitoring device 30. The conveying device 10 is connected to the upstream equipment and is used to receive the box to be foamed. The conveying device 10 may include a weighing component 11 and at least one preset station 12. The weighing component 11 may be respectively set at the input end and the output end of the conveying device 10, and is used to weigh the first weight information of the box to be foamed before foaming and the second weight information after foaming. The preset station 12 is equipped with a foaming mold. There may be multiple preset stations 12, and different preset stations 12 are equipped with different foaming molds. Different foaming molds correspond to different types of boxes to be foamed.

[0062] The filling device 20 is used to foam the boxes to be foamed located in the preset workstations 12. When there are multiple preset workstations 12, the filling device 20 can move back and forth between different preset workstations 12. For example, if there are four preset workstations 12, the filling device 20 can move to any one of the four preset workstations 12 and foam the boxes to be foamed in the preset workstation 12. During foaming, the filling device 20 can foam one by one. For example, it can foam each box to be foamed in each preset workstation 12 one by one according to a preset order.

[0063] The monitoring device 30 can acquire first and second weight information and determine whether the foaming chamber is qualified based on the first and second weight information. For example, if the first weight information is A kg and the second weight information is B kg, then subtracting A kg from B kg yields C kg, where A, B, and C are all positive numbers. The qualification of the foaming chamber can then be determined based on C kg. If C kg is within the preset qualified range, it indicates that the foaming of the chamber is qualified and can proceed to the next stage. If C kg is outside the preset qualified range, it indicates that the foaming of the chamber is unqualified and a warning message can be generated. The warning message can include the foaming parameters of the chamber during this foaming process, such as the ratio of black and white materials, the pressure of black and white materials, and the flow rate of black and white materials, facilitating user analysis of the reasons for foaming failure. It is understood that the preset qualified range is a numerical interval. When C kg is within the numerical interval, it indicates that the foaming chamber is qualified; when C kg falls outside the numerical interval, it indicates that the foaming chamber is unqualified.

[0064] As a further embodiment, the conveying device 10 includes an identification component 13 and a transmission component 14; the identification component 13 is located at the input end of the transmission component 14, and is used to acquire the configuration information of the foaming box to be foamed, and send the configuration information to the monitoring device 30; the transmission component 14 is used to convey the foaming box to a preset workstation 12 that matches the foaming box.

[0065] The identification component 13 can be a barcode scanner. The foaming box can have an identification code. The barcode scanner can obtain the configuration information of the foaming box by scanning the identification code, and then confirm the preset workstation 12 that matches the foaming box. For example... Figure 6 As shown, Figure 6 There are four preset workstations 12 from left to right. When the foam box to be foamed enters from the left, the identification component 13 scans the identification code to obtain the configuration information, and then sends the configuration information to the control device 40. The control device 40 confirms the preset workstation 12 matched with the foam box according to the configuration information, and then moves the foam box to be foamed to the corresponding preset workstation 12 through the transmission component 14. For example, if the second preset workstation 12 is the preset workstation 12 that matches the foam box to be foamed, the foam box to be foamed can be transported to the second preset workstation 12 through the transmission component 14. Figure 6 The middle arrow indicates the transmission direction of the transmission component 14. After the foaming of the box to be foamed is completed, it will be transported from the preset station 12 to the transmission component 14, and then the transmission component 14 will continue to transport it backward. In addition, a reader 121 can also be provided on one side of the preset station 12 to read the configuration information of the box to be foamed and send the configuration information to the monitoring device 30.

[0066] As a further embodiment, the weighing component 11 includes a first weighing element 111 and a second weighing element 112; the first weighing element 111 is disposed at the input end of the transmission component 14, and is used to acquire the first weight information of the box to be foamed before foaming, and send the first weight information to the monitoring device 30; the second weighing element 112 is disposed at the output end of the transmission component 14, and is used to acquire the second weight information of the box to be foamed after foaming, and send the second weight information to the monitoring device 30.

[0067] The weighing assembly 11 may include a first weighing element 111 and a second weighing element 112, such as... Figure 6 As shown, the first weighing element 111 can be located at the input end of the transmission component 14 to obtain the weight of the box to be foamed before foaming to obtain the first weight information. The second weighing element 112 can be located at the output end of the transmission component 14 to obtain the weight of the box to be foamed after foaming to obtain the second weight information.

[0068] In actual use, the foaming box enters from the left side, is weighed by the first weighing device 111, and is then transported by the transmission component 14 to the corresponding preset station 12. After foaming is completed in the preset station 12, the preset station 12 transports the foaming box back to the transmission component 14, and is then weighed by the second weighing device 112. If the foaming box is qualified, it proceeds to the next process; if the foaming box is unqualified, an early warning message is generated.

[0069] As a further embodiment, the filling device 20 includes a first dispensing component 21, a second dispensing component 22, a first driving component 23, a second driving component 24, a first spraying component 25, a second spraying component 26, and a discharge component 27; the first dispensing component 21 is connected to the first spraying component 25 through the first driving component 23, and the second dispensing component 22 is connected to the second spraying component 26 through the second driving component 24; both the first spraying component 25 and the second spraying component 26 are connected to the discharge component 27.

Both the first spraying component 25 and the second spraying component 26 may be spring nozzles, consisting of a slider and a spring, which can automatically extend and retract according to the flow rate to adjust the nozzle diameter, thereby stabilizing the injection pressure. The black material sprayed by the first spraying component 25 and the white material sprayed by the second spraying component 26 are ejected by the discharge component 27 into the foaming chamber within the preset station 12, thus completing the foaming of the foaming chamber.

[0071] The foaming monitoring system disclosed in this utility model can acquire the first weight information of the box to be foamed before foaming and the second weight information after foaming, and automatically confirm whether the box to be foamed is qualified based on the first weight information and the second weight information, thereby improving the detection efficiency.
