Description

Technical Field

[0001] This application relates to the technical field of refrigerator manufacturing, and in particular to a method, system and storage medium for preventing errors in refrigerator assembly lines. Background Technology

[0002] A refrigerator is a common consumer product used to keep food or other items at a constant low temperature. It includes a cabinet, compressor, instruction set, and other refrigeration devices.

[0003] In the existing refrigerator production assembly line model, operators sort the corresponding products in the material warehouse, place the materials on the assembly conveyor belt according to the product assembly order, and assemble them sequentially according to the product assembly order.

[0004] Because different countries have different requirements for compressor and temperature control models, even the same refrigerator model needs to have different models of compressor and temperature control installed in the refrigerator body when assembling orders for different countries, according to the requirements of the exporting country. After the compressor and temperature control are installed, the compressor needs to be welded to fix it in the refrigerator body. Therefore, the compressor and temperature control in the refrigerator body need to be confirmed during the welding process.

[0005] In refrigerator assembly lines using related technologies, after workers install the compressor and temperature control, the next installer manually checks the refrigerator body and the compressor and temperature control inside the body. This method of error prevention is not only inefficient but also prone to errors. Summary of the Invention

[0006] To improve the efficiency of error prevention checks during refrigerator installation, this application provides an error prevention method, system, and storage medium for refrigerator assembly lines.

[0007] Firstly, this application provides a method for preventing errors in a refrigerator assembly line, employing the following technical solution:

[0008] A method for preventing errors in a refrigerator assembly line includes the following steps:

[0009] Obtain first identification information obtained by scanning the first identifier with the first scanner, wherein the first identification information includes the compressor model and parameters;

[0010] Obtain the second identification information obtained by scanning the second identification object with the second scanned document. The second identification information includes the model, parameters, and target country of the container.

[0011] Obtain third identification information obtained by scanning a third identifier with a third scanner, wherein the third identification information includes the model and parameters of the temperature controller;

[0012] Determine whether the first and second identification information match the order information in the database;

[0013] If a match is found, the temperature control information matching the second identification information is retrieved from the database, and the temperature control information is compared with the third identification information. If the temperature control information matches the third identification information, the third identification information is sent to the temperature control installation station to output temperature control prompt information to characterize different models of temperature control.

[0014] If a mismatch occurs, an error message will be displayed and the assembly line will be stopped.

[0015] In some embodiments, obtaining the first identification information, the second identification information, and the third identification information further includes the following steps:

[0016] Obtain a first identification result, wherein the first identification result indicates whether the first identification information can be obtained;

[0017] Obtain a second identification result, which indicates whether the second identification information can be obtained;

[0018] Obtain a third identification result, which indicates whether third identification information can be obtained;

[0019] If the first identification result is that the first identification information can be obtained, and the second identification result is that the second identification information cannot be obtained and / or the third identification result is that the third identification information cannot be obtained, then the current image of the area where the second and / or third identification information cannot be obtained is obtained;

[0020] Obtain a target image in which the preset second and / or third markers are in the correct positions;

[0021] The positions of the second and / or third markers in the current image are compared with the positions of the second and / or third markers in the target image to obtain distance information;

[0022] The positions of the second and / or third scanners are adjusted using the distance information until the second and / or third identification information is obtained.

[0023] In some of these embodiments, if the first identification result is that the first identification information cannot be obtained, and the second identification result is that the second identification information cannot be obtained and the third identification result is that the third identification information cannot be obtained, then the reflection time difference of the scanning signals at both ends of the second scanning component in the horizontal direction is obtained.

[0024] The rotation angle of the box is obtained based on the reflection time difference, and the corresponding angle signal is output.

[0025] Adjust the position of the housing according to the angle signal until the first identification information, the second identification information, and the third identification information are obtained.

[0026] In some embodiments, if the first identification information and the second identification information match order information in the database, the method further includes:

[0027] The first identification information is sent to the component library, which contains multiple combinations of components associated with different compressors;

[0028] Obtain component information that matches the first identification information from the component library;

[0029] The component information is sent to the component packaging station to output component prompt information corresponding to different compressor models, wherein the component prompt information includes image information and text information.

[0030] Secondly, this application provides a refrigerator assembly line error prevention system, which adopts the following technical solution:

[0031] A refrigerator assembly line error prevention system includes a cloud platform, a first scanner, a second scanner, a third scanner, a bracket, a first marker, a second marker, a third marker, a conveyor belt, and a temperature control mounting platform.

[0032] The conveyor belt is used to transport the box and the compressor that has been placed inside the box in advance;

[0033] The first identifier is mounted on the compressor, the second identifier is mounted on the outer wall of the housing, and the third identifier is also mounted on the outer wall of the housing. A bracket supports the first, second, and third scanning components. The bracket is positioned on one side of the conveyor belt. The first scanning component corresponds to the first identifier and is used to scan the first identifier to obtain first identification information, which includes the compressor's model and parameters. The second scanning component corresponds to the second identifier and is used to scan the second identifier to obtain second identification information, which includes the housing's model, parameters, and target export country. The third scanning component corresponds to the third identifier and is used to scan the third identifier to obtain third identification information, which includes the temperature control signal and parameters.

[0034] The cloud platform is used to acquire first identification information obtained by scanning a first identifier with a first scanner, acquire second identification information obtained by scanning a second identifier with a second scanner, and acquire third identification information obtained by scanning a third identifier with a third scanner. It then determines whether the first and second identification information match order information in a database located in the cloud platform. If they match, it retrieves temperature control information matching the second identification information from the database, compares the temperature control information with the third identification information, and if they match, sends the third identification information to the temperature control installation station to output temperature control prompt information indicating different temperature control models. If they do not match, it outputs an error message and stops the assembly line.

[0035] The temperature control installation platform is equipped with several types of temperature controllers. The temperature control installation platform receives the third identification information from the cloud and outputs corresponding temperature control prompts to prompt the operator to select the correct temperature controller.

[0036] In some embodiments, the support includes a first support and a second support, wherein the first support is arranged vertically and the second support is arranged horizontally, the second support is slidably disposed on the first support, the first scanning element is fixedly connected to the first support, and the second and third scanning elements are slidably connected to the second support. The first support is provided with a first driving component for moving the second support, and the second support is provided with a second driving component for moving the second and third scanning elements. The first driving component and the second driving component are electrically connected to the cloud.

[0037] The second scanning component is equipped with a camera, which is used to acquire the current image of the area where the first marker is located on the outer wall of the box.

[0038] The cloud platform is also used to acquire a first recognition result, which indicates whether first identification information can be acquired; acquire a second recognition result, which indicates whether second identification information can be acquired; acquire a third recognition result, which indicates whether third identification information can be acquired. If the first recognition result indicates that the first identification information can be acquired, and the second recognition result indicates that the second identification information cannot be acquired and / or the third recognition result indicates that the third identification information cannot be acquired, then the current image of the area where the second and / or third identification objects for which no recognition result can be acquired is acquired; a target image of the second and / or third identification objects in the correct position is acquired; the position of the second and / or third identification objects in the current image is compared with the position of the second and / or third identification objects in the target image to obtain distance information; and the position of the second and / or third scanning components is adjusted using the distance information until the second and / or third identification information is acquired.

[0039] In some embodiments, a component packaging table is also included, on which multiple sets of component combinations associated with different compressors are arranged;

[0040] The cloud platform is also used to send the first identification information to the component library when the first identification information and the second identification information match the order information in the database, and to obtain the component information that matches the first identification from the component library, the component library being contained in the cloud platform, and to send the component information to the component packaging station to output component prompt information corresponding to different models of compressors, wherein the component prompt information includes image information and text information.

[0041] Thirdly, this application provides a computer storage medium, which adopts the following technical solution:

[0042] A computer storage medium storing a computer program thereon, which, when executed by a processor, implements the aforementioned error-proofing method for refrigerator assembly lines.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. This method enables automatic detection of whether the containers and corresponding compressors and temperature controllers for export to different countries are installed correctly, eliminating the need for manual inspection. It is more efficient, stable and accurate in error prevention.

[0045] 2. By analyzing the first and second identification results, determine whether the second identification item on the box is missing or misaligned, or whether the box is placed on the conveyor belt at an incorrect angle. Adjust the position of the second scanning item or the position of the box accordingly to perform identification and reduce manual intervention.

[0046] 3. Obtain component information by matching the second identification information so that operators can correctly assemble and package the components in the data bag. Attached Figure Description

[0056] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0057] This application discloses a method for preventing errors in a refrigerator assembly line.

[0058] like Figure 1 As shown, a method for preventing errors in a refrigerator assembly line includes the following steps:

[0059] S100, Obtain the first identification information obtained by scanning the first identification object 1 by the first scanner 3.

[0060] The first identification information includes the model and parameters of compressor 5. The first identification object 1 is a paper barcode, which is pre-attached to compressor 5 by staff. The barcode contains pre-added relevant information associated with each compressor 5, which is the first identification information. The first scanning device 3 is an infrared scanner in this application, which can scan the first identification object 1, i.e., the barcode, to obtain the corresponding first identification information.

[0061] The placement of the first marker 1 is fixed, and operators need to try to place the first marker 1 in the correct position.

[0062] S200, Obtain the second identification information obtained by scanning the second identification object 2 by the second scanner 4.

[0063] The second identification information includes the model, parameters, and target export country of the refrigerator body 6. The second identification object 2 is a paper barcode, which is pre-attached to the back of the body 6 by staff, and the second identification object 2 and the first identification object 1 face the same direction. The barcode contains pre-added relevant information associated with each body 6, which constitutes the second identification information. The second scanning device 4 is an infrared scanner in this application, capable of scanning the second identification object 2, i.e., the barcode, to obtain the corresponding second identification information.

[0064] The placement of the second marker 2 is fixed, and operators need to try to place the second marker 2 in the correct position.

[0065] S300, acquire the third identification information obtained by scanning the third identification object 16 by the third scanner 15. The third identification information includes the model and parameters of the temperature controller.

[0066] The third identification information includes the model and parameters of the temperature controller. The third identification object 16 is a paper barcode, which is pre-attached to the back of the box 6 by staff, and the orientation of the third identification object 16 is the same as that of the first and second identification objects. The barcode contains pre-added relevant information associated with each temperature controller, which is the third identification information. The third scanning device 15 in this application is an infrared scanner, which can scan the third identification object 16, i.e., the barcode, to obtain the corresponding second identification information.

[0067] S400, determine whether the first identification information and the second identification information match the order information in the database.

[0068] The database is pre-set and stores order information for different orders. The order information contains the first and second identification information corresponding to the order, which is the country to which the refrigerator will be exported, the model parameters of the refrigerator body 6, and the model parameters of the compressor 5 specified in the target export country.

[0069] After obtaining the first and second identification information through scanning, these two identification information are matched with the order information of the order in the database to determine whether they match.

[0070] To avoid confusion between multiple orders, the order information in the database should be arranged into corresponding queues according to the assembly work objectives, so that the order of several order information in the queue is the same as the order of the housing 6 and compressor 5 being assembled on the assembly line.

[0071] S500, if a match is found, retrieve the temperature control information that matches the second identification information from the database, compare the temperature control information with the third identification information, if the temperature control information matches the third identification information, and send the third identification information to the temperature control installation station to output temperature control prompt information to characterize different models of temperature control.

[0072] If the first and second identification information match the order information, it means that the compressor 5 and the housing 6 are compatible. In this case, it is necessary to consider the correct assembly of the temperature control.

[0073] After obtaining the matching information, the third identifier information matching the second identifier information is retrieved from the database. Since the temperature control and the refrigerator body 6 are associated in a refrigerator, and the temperature control matched with a specific model of refrigerator body 6 is fixed, each temperature control is entered into the database according to its model and parameters to obtain and save the corresponding temperature control information. When a second identifier information is entered, the matching temperature control information can be obtained from the database.

[0074] The temperature control information in the database indicates the temperature control model that matches the enclosure. The third identification information on the enclosure is manually affixed beforehand, which serves as a signal to the operator on the temperature control installation station 8 to install the temperature control on the enclosure 6. To prevent the operator from affixing the wrong model temperature control identification, the third identification information needs to be compared with the temperature control information. If they are the same, the installer on the temperature control installation station 8 can install the temperature control according to the corresponding temperature control prompt information.

[0075] After the third identification information is matched with the temperature control information, the corresponding third identification information is sent to the temperature control mounting station 8. The temperature control mounting station 8 has several different models of temperature controllers. When the third identification information is received, the third identification information is converted into temperature control prompt information and displayed through indicator lights, display screens and other methods to prompt the operator to select the appropriate temperature controller and proceed to the subsequent welding stage.

[0076] Furthermore, since the temperature controller is installed manually, even if the correct temperature control prompt information is obtained, the operator may still install the wrong temperature controller in the cabinet 6 due to negligence. Therefore, a corresponding label can be attached to each temperature controller on the temperature controller mounting platform 8, and the label on the temperature controller can be scanned before installation. If the scan result does not match the third label information, an alarm will still be issued, thereby improving the error prevention effect of the installation.

[0077] If S600 does not match, an error message will be output and the assembly line will be stopped.

[0078] If the first and second identification information do not match the order information in the database, it indicates that there is an assembly error in compressor 5 or housing 6. In this case, the assembly line needs to be stopped and an error message should be output to prompt the operator to replace housing 6 or compressor 5 in time.

[0079] This method enables automatic detection of whether the container 6 and its corresponding compressor 5 and temperature control are correctly installed for export to different countries, eliminating the need for manual inspection. This method is more efficient, stable, and accurate in preventing errors.

[0080] Furthermore, because the appearance of some different refrigerator models 6 and compressor 5 is similar, if the operator checks manually, it is not possible to intuitively determine whether the model of the refrigerator 6 and the model of the compressor 5 match. The operator needs to obtain the model parameters of the similar-looking refrigerator 6 and compressor 5 through the corresponding instruction manual or parameter book, which is prone to errors. The method of this application effectively solves this problem. The model of the refrigerator 6 and compressor 5 are stored on the corresponding identification object, and there will be no identification error when scanning the scanned document.

[0081] In another embodiment, the first and second identification information may not need to be compared with the order information. Since the compressor 5 models corresponding to the boxes 6 exported to different countries are relative, it is only necessary to send the first and second identification information to the database and compare them with the preset combination information of boxes 6 and compressor 5. For example, the database stores combinations such as box A 6 + compressor B 5, box C 6 + compressor D 5, box E 6 + compressor F 5, etc. If the first identification information is box C 6 and the second identification information is compressor F 5, it is directly determined that the combination of box C 6 + compressor F 5 does not exist in the database. That is, compressor F 5 does not match box C 6, so there is an error in the assembly of compressor 5.

[0082] This method does not take into account the refrigerator assembly order in the order and is suitable for situations where production is carried out first to fill inventory and then the refrigerators are sold. In this case, it is only necessary to install the correct compressor 5 according to the cabinet 6.

[0083] like Figure 2 As shown, furthermore, when the operator places the refrigerator body 6 and compressor 5 on the conveyor belt 7, the body 6 may be placed crookedly or the labels may be affixed crookedly. In this case, some errors may occur when the scanner scans them. Therefore, this application also includes the following steps when obtaining the first identification information, the second identification information, and the third identification information:

[0084] S600, obtain the first recognition result.

[0085] The first identification result is characterized by whether the first identification information can be obtained. In other words, the first identification result includes "can obtain the first identification information" and "cannot obtain the first identification information".

[0086] S610, obtain the second recognition result.

[0087] The second identification result is characterized by whether the second identification information can be obtained. In other words, the second identification result includes "can obtain the second identification information" and "cannot obtain the second identification information".

[0088] S620, obtain the third recognition result.

[0089] The second identification result is characterized by whether the third identification information can be obtained. In other words, the third identification result includes "can obtain the third identification information" and "cannot obtain the third identification information".

[0090] S630, if the first identification result is that the first identification information can be obtained, and the second identification result is that the second identification information cannot be obtained and / or the third identification result is that the third identification information cannot be obtained, then the current image of the area where the second identification object and / or the third identification object where the identification result cannot be obtained is obtained.

[0091] If the first identification information can be obtained, but the second and / or third identification information cannot be obtained, that is, the barcode on the compressor 5 can be identified, but the barcode on the box 6 cannot be identified, it means that the orientation of the box 6 is correct, but the affixing position of the second identification 2 and / or the third identification 16 on the box 6 is deviated or the second identification 2 and / or the third identification 16 are not affixed.

[0092] At this time, the camera function on the second scanner 4 is used to capture an image on the box 6. This image can be an overall image of the box 6 or an image of the area where the second marker 2 and the third marker 16 are pasted. This application is to obtain the current image of the location of the second marker 2 and the third marker 16.

[0093] Image analysis can determine whether the second marker 2 and / or the third marker 16 were not pasted or whether the pasting position of the second marker 2 and / or the third marker 16 was deviated.

[0094] If the second identifier 2 and / or the third identifier 16 are not affixed, an error message will be output and the assembly line will be stopped.

[0095] S640, acquire a target image in which the preset second marker 2 and / or third marker 16 are in the correct position.

[0096] S650, compare the positions of the second marker 2 and / or the third marker 16 in the current image with the positions of the second marker 2 and / or the third marker 16 in the target image to obtain distance information.

[0097] If a deviation in the position of the second marker 2 and / or the third marker 16 is detected, first, a target image of the second marker 2 and / or the third marker 16 in the correct position is acquired. That is, an image of the second marker 2 and / or the third marker 16 when it is correctly positioned is pre-set. Then, the position of the second marker 2 and / or the third marker 16 in the current image is acquired. This can be achieved by establishing coordinates in both vertical and horizontal directions to determine the coordinates of a specific point of the second marker 2 and / or the third marker 16 in the current image, such as the corner position or the center point.

[0098] Finally, two sets of coordinate points are obtained: one set represents the coordinate points when the second marker 2 and / or the third marker 16 are pasted in the correct position, and the other set represents the coordinate points of the pasted position of the second marker 2 and / or the third marker 16 in the currently captured image. Based on these two sets of coordinate points, the corresponding distance information is calculated. The distance information refers to the distance between the pasted position of the second marker 2 and / or the third marker 16 in the current image and the target pasted position in the vertical and horizontal directions.

[0099] S660, adjust the position of the second scanner 4 and / or the third scanner 15 using distance information until the second identification information and / or the third identification information are obtained.

[0100] The positions of the second scanner 4 and / or the third scanner 15 are adjusted based on the calculated distance information until the second identification information can be obtained. The conversion between the difference between coordinate points and the specific distance length can be adjusted accordingly based on the actual usage.

[0101] It should be noted that after the position of the second scanned part 4 and / or the third scanned part 15 is adjusted and moved, after scanning the first marker 1, it is necessary to return to the starting position to avoid the second marker 2 and / or the third marker (16) in the preset target image changing the correct pasting position coordinates after not returning to the starting position.

[0102] In cases where the first identification information can be identified but the second and / or third identification information cannot be identified, another possibility exists: the operator may misplace the second and / or third identification 16 when affixing them. In such cases, the second identification 2 may not be identified even when the second scanner 4 is moved. In this situation, barcode identification can be performed using the image captured by the camera 9.

[0103] like Figure 3 As shown, in another embodiment, the following steps are also included:

[0104] S670, if the first identification result is that the first identification information cannot be obtained, and the second identification result is that the second identification information cannot be obtained, and the third identification result is that the third identification information cannot be obtained, then the reflection time difference of the scanning signals at both ends of the second scanning component 4 in the horizontal direction is obtained.

[0105] If the first, second, and third identification information cannot be identified, the situation may be that the operator did not place the box 6 on the conveyor belt 7 at the correct angle, causing the placement angle of the box 6 to deviate, resulting in the box 6 and the compressor 5 placed inside the box 6 not being able to face the scanned item correctly.

[0106] In this case, it is necessary to determine the placement deviation angle of box 6. The specific determination method is as follows:

[0107] The second scanning element 4 emits an infrared laser, and the laser of the second scanning element 4 has a certain width along the horizontal direction. When the infrared laser at one end of the second scanning element 4 is emitted and reflected by the surface of the box 6, the round-trip time of the infrared laser at one end of the second scanning element 4 is obtained. Similarly, the round-trip time of the infrared laser at the other end of the second scanning element 4 is obtained. Since the box 6 is placed with a certain deviation, the round-trip time of the infrared laser on both sides must be different. The reflection time difference between the two is calculated.

[0108] like Figure 4 As shown, when the placement angle of the box 6 on the conveyor belt is not opposite to the infrared laser direction of the second scanning element 4 and the first scanning element 3, one end of the second scanning element 4 is closer to the box 6, and the round-trip time of the infrared laser at this end is set as A. The other end is farther from the box 6, and the round-trip time of the infrared laser at this end is set as B. The difference between A and B is calculated to obtain the reflection time difference, and the deflection angle is calculated based on the reflection time difference.

[0109] Similarly, an infrared laser emitter can also be installed on the third scanning element 15.

[0110] S680 obtains the rotation angle of the housing 6 based on the reflection time difference and outputs the corresponding angle signal.

[0111] After prior debugging and experimentation, the functional relationship between the reflection time difference and the rotation angle of the housing 6 can be obtained and saved, so that when a reflection time difference is obtained, the corresponding angle signal can be output.

[0112] The reflection time difference can have positive and negative values. For example, if the round-trip time on the left side of the second scanning element 4 is greater than that on the right side, the reflection time difference is positive; otherwise, it is negative. Correspondingly, the rotation angles relative to positive and negative reflection time differences also have corresponding positive and negative values. The positive and negative values ​​indicate whether the housing 6 is deviating clockwise or counterclockwise.

[0113] S690, adjust the position of the housing 6 according to the angle signal until the first identification information, the second identification information and the third identification information are obtained.

[0114] The position of the housing 6 is adjusted by the angle signal, that is, the housing 6 is rotated until it is rotated to the correct angle so that the first marker 1, the second marker 2 and the third marker 16 are all facing the first scanner 3, the second scanner 4 and the third scanner 15.

[0115] Since the compressor 5 is small in size, the possibility that the operator forgets to stick the first identifier 1 on the compressor 5 or that the sticking position of the first identifier 1 is deviated is small. The possibility that the first scanner 3 cannot scan the first identifier 1 is low. Therefore, the first identification result of the first scanner 3 is used as the benchmark in this application.

[0116] If the first identification information cannot be scanned but the second identification information can be identified, the verification step can be skipped, a prompt message can be output directly, and the assembly line can be stopped. This is because the probability of this situation is low, and if it does occur, it is highly likely that the compressor 5 has been missed.

[0117] like Figure 5 As shown, in another embodiment, if the first identification information and the second identification information match the order information in the database, the method further includes the following steps:

[0118] S700 sends the first identification information to the component library.

[0119] S710 retrieves component information that matches the first identification information from the component library.

[0120] S720 sends component information to the component packaging station 10 to output component prompt information corresponding to different models of compressors 5.

[0121] Once the compatibility between the refrigerator body 6, compressor 5, and temperature controller is confirmed, the corresponding document bags for the refrigerator must be assembled and packaged. These document bags contain information such as the instruction manual, specifications, energy efficiency data, and key. These components are pre-categorized and placed on the component packaging table 10.

[0122] Since different compressors 5 require different components, after the first identification information is sent to the component library, the component library outputs different component information to the component packaging table 10 based on the different first identification information. The component library is pre-set and includes information on all components used for each model of compressor 5.

[0123] After receiving the component information, the component packaging station 10 outputs and displays corresponding component prompts. These prompts include both image and text information, indicating that the operator on the component packaging station 10 can place the corresponding components into the same document bag based on the displayed images and instructions, complete the assembly of the document bag, and finally pack the document bag and the refrigerator together.

[0124] like Figure 6As shown, in another embodiment, a refrigerator assembly line error prevention system is also disclosed, which includes a cloud 14, a first scanner 3, a second scanner 4, a third scanner 15, a bracket 11, a first marker 1, a second marker 2, a third marker 16, a conveyor belt 7, and a temperature control mounting platform 8.

[0125] The conveyor belt 7 is used to transport the refrigerator body 6 and the compressor 5, which is placed inside the refrigerator body 6 in advance. It is connected end to end, so that the conveyor belt 7 will continue to transport refrigerators back and forth after transporting one refrigerator.

[0126] like Figure 6 and Figure 7 As shown, the first identifier 1 is a paper barcode, which is pre-attached to the compressor 5 by staff. The barcode contains pre-added information associated with each compressor 5, i.e., the first identifier information. The first scanner 3 in this application is an infrared scanner, which can scan the first identifier 1, i.e., the barcode, to obtain the corresponding first identifier information.

[0127] The second identifier 2 is a paper barcode, which is pre-attached to the box 6 by staff. The second identifier 2 and the first identifier 1 face the same direction. The barcode contains pre-added relevant information associated with each box 6, which is the second identifier information. The second scanner 4 is an infrared scanner in this application, which can scan the second identifier 2, i.e., the barcode, to obtain the corresponding second identifier information.

[0128] The third identifier 16 is a paper barcode, which is pre-attached to the box 6 by staff. The third identifier 16 and the first identifier 1 face the same direction. The barcode contains pre-added information related to each temperature controller, i.e., the third identifier information. The third scanner 15 is an infrared scanner in this application, capable of scanning the third identifier 16 (the barcode) to obtain the corresponding third identifier information. The third identifier 16 and the second identifier 2 are at the same horizontal level.

[0129] like Figure 6 and Figure 8 As shown, the bracket 11 is set on one side of the conveyor belt 7 to fix the first scanning element 3 and the second scanning element 4. When the refrigerator body 6 and the compressor 5 are transported and pass by on the conveyor belt 7, the first scanning element 3 can scan the first marker 1, the second scanning element 4 can scan the second marker 2, and the third scanning element 15 can scan the third marker 16.

[0130] The cloud-based unit 14 is used to acquire the first identification information obtained by the first scanner 3 scanning the first identifier 1, the second identification information obtained by the second scanner 4 scanning the second identifier 2, and the third identification information obtained by the third scanner 15 scanning the third identifier 16. It also determines whether the first and second identification information match the order information in the database, which is located in the cloud-based unit 14. If they match, it retrieves the temperature control information that matches the second identification information from the database, compares the temperature control information with the third identification information, and if the temperature control information matches the third identification information, it sends the third identification information to the temperature control mounting station 8 to output temperature control prompt information to characterize different models of temperature control. If they do not match, it outputs an error prompt and stops the assembly line.

[0131] The temperature control mounting station 8 is equipped with several types of temperature controllers. It receives third-party identification information from the cloud platform 14 and outputs corresponding temperature control prompts to guide the operator in selecting the correct temperature controller. The temperature control mounting station 8 is located in the next work area after the first and second scanning components 3 and 4 have been scanned.

[0132] Furthermore, a partition 12 is provided around the outside of the bracket 11. The partition 12 serves a protective function to prevent external factors from affecting the scanning effect of the first scanning element 3, the second scanning element 4, and the third scanning element 15. The partition 12 is provided with a through hole 13, which facilitates observation by the operator and also facilitates heat dissipation.

[0133] The first scanned document 3, the second scanned document 4, and the third scanned document 15 can be installed by plugging them together. An illumination device can be installed between the three scanned documents to increase the brightness near the barcode and improve the accuracy of the first scanned document, the second scanned document 4, and the third scanned document 15.

[0134] Furthermore, the bracket 11 includes a first bracket 111 and a second bracket 112, wherein the first bracket 111 is arranged vertically and the second bracket 112 is arranged horizontally. The second bracket 112 is slidably mounted on the first bracket 111. The first scanning element 3 is fixedly connected to the first bracket 111, and the second scanning element 4 and the third scanning element 15 are slidably connected to the second bracket 112. The first bracket 111 is provided with a first driving assembly for moving the second bracket 112, and the second bracket 112 is provided with a second driving assembly for moving the second scanning element 4 and the third scanning element. The first driving assembly and the second driving assembly are electrically connected to the cloud 14.

[0135] The second scanning component 4 is equipped with a camera 9, which is used to acquire the current image of the area where the second marker 2 and the third marker 16 are located on the outer wall of the box 6.

[0136] The cloud 14 is also used to obtain a first recognition result, which indicates whether the first identification information can be obtained; to obtain a second recognition result, which indicates whether the second identification information can be obtained; and to obtain a third recognition result, which indicates whether the third identification information can be obtained. If the first recognition result indicates that the first identification information can be obtained, and the second recognition result indicates that the second identification information cannot be obtained and / or the third recognition result indicates that the third identification information cannot be obtained, then the current image of the area where the second identifier 2 and / or the third identifier 16 cannot be identified is obtained; the target image of the second identifier 2 and / or the third identifier 16 being in the correct position is obtained; the position of the second identifier 2 and / or the third identifier 16 in the current image is compared with the position of the second identifier 2 and / or the third identifier 16 in the target image to obtain distance information; and the position of the second scanner 4 and / or the third scanner 15 is adjusted according to the distance information until the second identification information and / or the third identification information are obtained.

[0137] When the cloud 14 can obtain the first identification information but cannot obtain the second and / or third identification information, the cloud 14 controls the camera 9 to open and take pictures of the box 6.

[0138] Upon receiving the distance signal, the cloud 14 controls the first and second drive components to operate, thereby controlling the second bracket 112 to move vertically along the length of the first bracket 111, and controlling the second scanning element 4 and / or the third scanning element 15 to move horizontally along the length of the second bracket 112.

[0139] The first and second driving components can be any driving components from related technologies, as long as they meet the effects described in this application.

[0140] In another embodiment, a rotating mechanism is provided on the conveyor belt 7 to drive the box 6 to rotate. The rotating mechanism is electrically connected to the cloud 14. The second scanning element 4 includes a signal transmitting end and a signal receiving end.

[0141] The cloud 14 is also used to obtain the reflection time difference of the scanning signals at both ends of the second scanning component 4 in the horizontal direction when the first identification result is that the first identification information cannot be obtained, the second identification result is that the second identification information cannot be obtained, and the third identification result is that the third identification information cannot be obtained; obtain the rotation angle of the box 6 according to the reflection time difference, and output the corresponding angle signal; send the angle signal to the rotation mechanism to adjust the position of the box 6 until the first identification information is obtained.

[0142] In this application, the rotating mechanism consists of a disc and a corresponding drive motor. The drive motor drives the disc to rotate, and the rotation of the disc causes the housing 6 on the disc to rotate. The conveyor belt 7 can be equipped with several drive motors and discs, and each disc can hold one housing 6.

[0143] The rotating mechanism can be set to any rotation method in the prior art, as long as it meets the effect required in this application.

[0144] In another embodiment, a component packaging table 10 is also included, on which multiple sets of components associated with different compressors 5 are disposed. The component packaging table 10 is located in the working area following the temperature control mounting table 8.

[0145] The cloud 14 is also used to send the first identification information to the component library when the first identification information and the second identification information match the order information in the database, and to obtain the component information that matches the first identification from the component library. The component library is included in the cloud 14. The component information is sent to the component packaging station 10 to output component prompt information corresponding to different models of compressors 5. The component prompt information includes image information and text information.

[0146] In another embodiment, a computer storage medium is also disclosed, on which a computer program is stored, which, when executed by a processor, implements the above-described error-proofing method for refrigerator assembly lines.

[0147] The implementation principle is as follows:

[0148] This method enables automatic detection of whether the container 6 and its corresponding compressor 5 and temperature control are correctly installed for export to different countries, eliminating the need for manual inspection. This method is more efficient, stable, and accurate in preventing errors.

[0149] Furthermore, because the appearance of some different refrigerator models 6 and compressor 5 is similar, if the operator checks manually, it is not possible to intuitively determine whether the model of the refrigerator 6 and the model of the compressor 5 match. The operator needs to obtain the model parameters of the similar-looking refrigerator 6 and compressor 5 through the corresponding instruction manual or parameter book, which is prone to errors. The method of this application effectively solves this problem. The model of the refrigerator 6 and compressor 5 are stored on the corresponding identification object, and there will be no identification error when scanning the scanned document.

[0150] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
