[0050] In order to more clearly illustrate the implementation cases of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0051] The first embodiment of the present invention is a multi-mode scanning code tracing system, such as Figure 1 As shown, it includes: a first code scanning device 1, which is used to identify the identification information on the surface of the production material; a tracing device 2, which is used to process the identification information of the production material and store the product traceability information according to the pre-configured traceability rules; a control device 3, which is connected to the first code scanning device 1 and the tracing device 2 respectively, and is used to control the first code scanning device 1 to identify the identification information of the production material and transmit it to the tracing device 2 when determining that the current process meets the code scanning requirements; and receive the processing results fed back by the tracing device 2 and control the production device to perform subsequent actions according to the processing results.

[0052] In this embodiment, the first barcode scanning device 1 is used to identify identification information on production materials. It can be a visual barcode scanning device, a fixed barcode scanner, a handheld barcode scanner, etc., supporting multiple scanning methods. The control device 3 is used to control the first barcode scanning device 1 and transmit the identification information of the production materials to the traceability device 2, as well as receive feedback from the traceability device 2 and control the device 3 to perform actions. It can be a programmable controller (PLC), a visual information acquisition device, etc.

[0053] Traceability device 2 is used to process the identification information of production materials and store product traceability information according to preset traceability rules. Traceability device 2 receives transmitted data in real time, parses, verifies, and stores it to ensure the accuracy and completeness of the traceability information. To achieve the objectives of the invention, traceability device 2 supports customizable traceability rules, such as batch and single-item traceability, and can be flexibly configured based on the company's specific needs. The internal configuration of the database parses the identification information of production materials. The database can adopt a distributed database architecture to ensure high data availability and scalability. The database stores product traceability information, including production data, quality inspection data, and logistics information.

[0054] The types of identification information for production materials include, but are not limited to, QR codes and barcodes. The types of printing for identification information include, but are not limited to, paper printing, laser engraving, inkjet printing, etc. The materials of production materials include, but are not limited to, injection molded parts, electronic circuit boards, and metal parts.

[0055] During operation, when control device 3 determines whether the current process meets the scanning requirements, that is, when production materials arrive at the designated location, it automatically triggers first scanning device 1 to scan the production materials. First scanning device 1 then identifies the identification information on the production materials' surfaces. The identification result is then transmitted to control device 3, which then transmits it to traceability device 2, which performs error prevention and records the result. Finally, control device 3 controls other production devices to execute the next step based on the processing results fed back by traceability device 2.

[0056] In this embodiment, the first barcode scanning device 1 performs autonomous barcode scanning under the control of the control device 3, and the system enters the equipment autonomous barcode scanning mode. The barcode scanning traceability in this mode is suitable for equipment processes with a high degree of automation. The tooling equipment can be well combined with the barcode scanning device, and the location and type of material identification information can be well identified. Once a traceability rule verification error occurs for a production material or the barcode scanning device fails to identify it, the station will be directly passed according to the actual needs of the workstation. The loading station can also set the control device to alarm, and then manually change the material, and the operating device will perform autonomous barcode scanning again.

[0057] The above embodiment is improved to obtain this embodiment, as shown in FIG. Figure 2As shown, in this embodiment, the multi-mode barcode scanning and traceability system also includes: a second barcode scanning device 4, which is used to identify identification information on the surface of production materials and send the identification information to the user interaction device for display; a first user interaction device 5, which is connected to the second barcode scanning device 4, the control device 3, and the traceability device 2, and is used to display the first barcode scanning prompt information and status, display the processing results fed back by the traceability device 2, the binding and unbinding of production materials, and configure traceability rules. The control device 3 is also used to send a barcode reading message to the traceability device 2 when it determines that the current process meets the barcode scanning requirements; the traceability device 2 is also used to send the first barcode scanning prompt information to the first user interaction device 5 for display after receiving the barcode reading message sent by the control device 3.

[0058] In this embodiment, the second barcode scanning device 4 is similar to the first barcode scanning device 1 and is used to identify identification information on production materials. It can also be a visual barcode scanning device, a fixed barcode scanner, a handheld barcode scanning gun, etc., and supports multiple scanning methods.

[0059] The first user interaction device 5 can be an operable fixed or removable device such as a tablet computer, which has a user interface for user interaction installed inside. Users can perform information query, material unbinding, configuration traceability rules and other functions in the user interface according to the configured permissions (different users can perform different operations, and different functions have different operation permission levels). In one example, the unbinding of production materials in the user interface must be authorized by senior operators, and configuring traceability rules is the exclusive authority of process personnel. That is, the unbinding function of production materials on the user interface is used when there is an error in the binding of key materials other than the main material. A senior operator, such as a production line team leader, must enter a password or switch login information to unbind. Ordinary operators do not have the authority to unbind materials to prevent misoperation.

[0060] During operation, when control device 3 determines whether the current process meets the code scanning requirements, that is, when production materials have arrived at the designated location, control device 3 immediately transmits the code reading information to traceability device 2. Traceability device 2 then prompts the user to scan the code information through first user interaction device 5, displaying the first code scanning prompt on first user interaction device 5. Based on the prompt, the operator uses second code scanning device 4 to identify the identification information on the production materials of the corresponding product. The identification information is sent to the user interaction device for display and simultaneously transmitted to traceability device 2 for automatic entry. Traceability device 2 then performs error prevention and records the information. Ultimately, control device 3 controls other production devices to execute the next step based on the processing results fed back by traceability device 2.

[0061] Furthermore, the first user interaction device 5 is further configured to determine whether a new production material needs to be replaced and re-scanned based on the processing results fed back by the traceability device 2. If so, the production material is decoded based on the unbinding information received by the user and the new production material is specified based on the binding information. In other words, when the first user interaction device 5 determines that a new scan is required, the operator, based on the user's permission, unbinds the material, replaces the production material, and re-scans the code.

[0062] In this embodiment, when the production material reaches the specified position, the device triggers the flat-panel scanning mode. This method is suitable for the situation where the scanning position is flexible and it is difficult to combine with the tooling for fixed scanning. It needs to be closely associated with the execution of the action by the control device 3 and must be triggered by the control device 3 before the scanning action can be performed. During the production process, the operator can directly use the second scanning device 4 to scan and identify the code. This method is suitable for scenes where the production material is relatively light or the material code is difficult to scan after being placed in the tooling equipment. In addition, the operator can also use the control device 3 to trigger the second scanning device 4 to scan the code (the control device 3 and the second scanning device 4 are connected). This is suitable for scenes where the material is relatively heavy or it is difficult to manually scan the code after the material is placed in the tooling equipment.

[0063] The above embodiment is improved to obtain this embodiment, as shown in FIG. Figure 3 As shown, in this embodiment, the multi-mode code scanning and traceability system also includes a third code scanning device 6 for identifying identification information on the surface of production materials and sending the identification information to the user interaction device and control device 3; a second user interaction device 7, connected to the third code scanning device 6 and the traceability device 2, respectively, for displaying the second code scanning prompt information and status, displaying the processing results fed back by the traceability device 2, the binding and unbinding of production materials, and configuring traceability rules. The traceability device 2 is also configured to send the second code scanning prompt information to the second user interaction device 7 for display when it determines that the current process meets the code scanning requirements.

[0064] In this embodiment, the third barcode scanning device 6 is similar to the first barcode scanning device 1 / the second barcode scanning device 4, and is used to identify identification information on production materials. It can also be a visual barcode scanning device, a fixed barcode scanner, a handheld barcode scanning gun, etc., and supports multiple scanning methods.

[0065] The second user interaction device 7 is similar to the first user interaction device 5. It can be an operable fixed or movable device such as a tablet computer, which has a user interface for user interaction installed inside. Users can perform information query, material unbinding, configuration traceability rules and other functions in the user interface according to the configured permissions (different users can perform different operations, and different functions have different operation permission levels). In one example, the unbinding of production materials in the user interface must be authorized by senior operators, and configuring traceability rules is the exclusive authority of process personnel. That is, the production material unbinding function on the user interface is used when there is an error in the binding of key materials other than the main material. A senior operator, such as a production line team leader, must enter a password or switch login information to unbind. Ordinary operators do not have the authority to unbind materials to prevent misoperation.

[0066] During operation, when traceability device 2 determines whether the current process meets the scanning requirements, i.e., when production materials have arrived at the designated location, it prompts the user 7 to scan the code, displaying a second scanning prompt on the user interaction device 7. Based on the prompt, the operator uses a third scanning device 6 to identify the identification information on the production materials of the corresponding product. This identification information is sent to the user interaction device for display and simultaneously transmitted to traceability device 2 for automatic entry. The traceability device 2 then performs error prevention and records the information. Ultimately, control device 3 controls other production equipment to execute the next step based on the processing results fed back by traceability device 2.

[0067] Furthermore, the second user interaction device 7 is also used to determine whether a new production material needs to be replaced and re-scanned based on the processing results fed back by the traceability device 2. If so, it decodes the production material according to the unbinding information received by the user and specifies the new production material according to the binding information. In other words, when the second user interaction device 7 determines that re-scanning is required, the operator unbinds the material, replaces the production material, and re-scans the code based on the user's permission.

[0068] In this embodiment, when the production materials reach the designated location, the tablet enters the autonomous scanning mode. This method is suitable for scenarios where the scanning position is flexible and it is difficult to combine with tooling for fixed scanning. It does not require waiting for the control device 3 signal and can perform scanning and identification at any time according to the production process.

[0069] In actual applications, the three scanning modes are suitable for different devices and scanning needs. Different selection and configuration can be made according to actual conditions, greatly improving the flexibility and accuracy of scanning: 1) In the device-autonomous scanning mode, the control device 3 will automatically trigger the first scanning device 1 to scan the identification information on the production material based on the detected material situation; 2) In the device-triggered tablet scanning mode, the control device 3 will send a code reading signal to the traceability device 2 after detecting that the material is in place. The traceability device 2 then prompts the scanning information through the tablet (first user interaction device 5). The operator uses the scanning device to identify the identification information on the corresponding production material according to the prompt information; 3) In the tablet scanning mode that does not require triggering, the operator controls the third scanning device 6 directly or through a trigger device to scan the code. Among them, the device-triggered tablet scanning mode and the tablet-autonomous scanning mode are not restricted by the production line layout and the degree of automation. They are suitable for production links with more manual intervention or temporary traceability needs, such as the need to install one or more key material stations.

[0070] Corresponding to the above multi-mode code scanning tracing system, the present invention also provides a multi-mode code scanning tracing method, such as Figure 4 Shown, including:

[0071] S101 control device determines whether the current process meets the code scanning requirements;

[0072] If yes in S102, the control device triggers the first code scanning device corresponding to the production material to identify the identification information;

[0073] S103: the first code scanning device transmits the recognized identification information to the control device;

[0074] S104: The control device receives the identification information of the production material and transmits it to the traceability device;

[0075] The S105 traceability device processes the identification information of production materials and stores product traceability information according to pre-configured traceability rules;

[0076] S106 The traceability system feeds back the processing results to the control device, and the control device performs subsequent actions based on the processing results.

[0077] In this embodiment, the first barcode scanning device is used to identify identification information on production materials. It can be a visual barcode scanning device, a fixed barcode scanner, a handheld barcode scanner, etc., supporting multiple scanning methods. The control device is used to control the first barcode scanning device and transmit the identification information of the production materials to the traceability device, as well as receive feedback from the traceability device and control the device to perform actions. It can be a programmable controller (PLC), a visual information acquisition device, etc.

[0078] The traceability device is used to process the identification information of growing materials and store product traceability information according to preset traceability rules. The traceability device is capable of receiving transmitted data in real time, parsing, verifying, and storing it to ensure the accuracy and completeness of the traceability information. To achieve the objectives of the invention, the traceability device supports custom traceability rules, such as batch traceability and single product traceability, which can be flexibly configured according to the actual needs of the enterprise. The internal configuration is controlled by a database to parse the identification information of production materials. The database can adopt a distributed database architecture to ensure high data availability and scalability. The database stores product traceability information, including production data, quality inspection data, logistics information, etc.

[0079] The types of identification information for production materials include, but are not limited to, QR codes and barcodes. The types of printing for identification information include, but are not limited to, paper printing, laser engraving, inkjet printing, etc. The materials of production materials include, but are not limited to, injection molded parts, electronic circuit boards, and metal parts.

[0080] During operation, when the control device determines whether the current process meets the scanning requirements, that is, when production materials arrive at the designated location, it automatically triggers the first scanning device to scan the production materials. The first scanning device then identifies the identification information on the production materials. The identification result is then transmitted to the control device, which then transmits it to the traceability device, which performs error prevention and records the result. Finally, the control device controls other production devices to perform the next action based on the processing results fed back by the traceability device.

[0081] In this embodiment, the first barcode scanning device performs autonomous scanning under the control of the control device, and the system enters the device autonomous scanning mode. The scanning traceability in this mode is suitable for equipment processes with a high degree of automation. The tooling equipment can be well integrated with the barcode scanning device, and the location and type of material identification information can be well identified. If there is an error in the traceability rule verification of the production material or the barcode scanning device fails to identify, it will be directly passed to the station according to the actual needs of the workstation. The loading station can also set the control device to alarm, and then manually change the material, and the operating device will perform autonomous scanning again.

[0082] The present invention also provides a multi-mode code scanning tracing method, such as Figure 5 Shown, including:

[0083] S201 controls the device to determine whether the current process meets the code scanning requirements;

[0084] If yes, the control device sends the code reading information to the traceability device at S202;

[0085] S203 The tracing device sends the first code scanning prompt information to the first user interaction device for display;

[0086] S204: The second barcode scanning device identifies the identification information on the surface of the production material and sends the identification information to the user interaction device for display, and at the same time transmits the identified identification information to the traceability device;

[0087] The S205 traceability device processes the identification information of production materials and stores product traceability information according to pre-configured traceability rules;

[0088] S206 The traceability system feeds back the processing results to the user interaction device for display;

[0089] S207 The user interaction device determines whether the code needs to be scanned again based on the feedback result;

[0090] If not required, the traceability system feeds back the processing result to the control device in S208, and the control device performs subsequent actions according to the processing result.

[0091] In this embodiment, the second barcode scanning device is similar to the first barcode scanning device and is used to identify identification information on production materials. It can also be a visual barcode scanning device, a fixed barcode scanner, a handheld barcode scanning gun, etc., and supports multiple scanning methods.

[0092] The first user interaction device can be an operable fixed or removable device such as a tablet computer, which has a user interface for user interaction installed inside. Users can perform information query, material unbinding, configuration traceability rules and other functions in the user interface according to the configured permissions (different users can perform different operations, and different functions have different operation permission levels). In one instance, the unbinding of production materials in the user interface must be authorized by senior operators, and configuring traceability rules is the exclusive authority of process personnel. That is, the production material unbinding function on the user interface is used when there is an error in the binding of key materials other than the main material. A senior operator, such as a production line team leader, must enter a password or switch login information to unbind. Ordinary operators do not have the authority to unbind materials to prevent misoperation.

[0093] During operation, when the control device determines whether the current process meets the code scanning requirements, that is, when the production material arrives at the designated location, it immediately sends the code reading information to the traceability device. The traceability device then prompts the user to scan the code information through the first user interaction device, and the first scan prompt information is displayed on the first user interaction device. Based on the prompt information, the operator uses the second code scanning device to identify the identification information on the production material of the corresponding product. The identification information is sent to the user interaction device for display and simultaneously transmitted to the traceability device for automatic entry. The traceability device then performs error prevention and records the information. Ultimately, the control device controls other production equipment to perform the next action based on the processing results fed back by the traceability device.

[0094] Furthermore, in step S207, the user interaction device determines whether it is necessary to re-scan the code according to the feedback result. If it is determined that it is necessary to re-scan the code, the user interaction device decodes the production material according to the unbinding information received by the authority, and specifies the new production material (corresponding to the binding information) according to the binding information. Figure 5 In step S209, the operator operates the second user interaction device to re-scan the code), and jumps to step S203. That is, when the first user interaction device determines that the code needs to be re-scanned, the operator unbinds the material on the first user interaction device according to the authority, replaces the production material, and re-scans the code.

[0095] In this embodiment, when the production material reaches the specified position, the device triggers the flat-panel scanning mode. This method is suitable for the situation where the scanning position is flexible and it is difficult to combine with the tooling for fixed scanning. It also needs to be closely associated with the execution of the action of the control device and must be triggered by the control device to perform the scanning action. During the production process, the operator can directly use the second scanning device to scan and identify the code. This method is suitable for scenarios where the production materials are relatively light or the material code is difficult to scan after being placed in the tooling equipment. In addition, the operator can also use the control device to trigger the second scanning device to scan the code (the control device and the second scanning device are connected). This is suitable for scenarios where the material is relatively heavy or it is difficult to manually scan the code after the material is placed in the tooling equipment.

[0096] The present invention also provides a multi-mode code scanning tracing method, such as Figure 6 Shown, including:

[0097] S301 tracing equipment determines whether the current process meets the code scanning requirements;

[0098] If yes in S302, the tracing device sends the second code scanning prompt information to the second user interaction device for display;

[0099] S303: The third barcode scanning device identifies the identification information on the surface of the production material and sends the identification information to the user interaction device for display, and at the same time transmits the identified identification information to the traceability device;

[0100] S304 traceability equipment processes the identification information of production materials and stores product traceability information according to pre-configured traceability rules;

[0101] S305 The traceability system feeds back the processing results to the user interaction device for display;

[0102] S306 The user interaction device determines whether the code needs to be scanned again based on the feedback result;

[0103] If not required, the traceability system will feed back the processing results to the control device in S307, and the control device will perform subsequent actions according to the processing results.

[0104] In this embodiment, the third scanning device is similar to the first scanning device / the second scanning device, and is used to identify identification information on production materials. It can also be a visual scanning device, a fixed scanner, a handheld scanning gun, etc., and supports multiple scanning methods.

[0105] The second user interaction device is similar to the first user interaction device. It can be an operable fixed or movable device such as a tablet computer, which has a user interface for user interaction installed inside. Users can perform information query, material unbinding, configuration traceability rules and other functions in the user interface according to the configured permissions (different users can perform different operations, and different functions have different operation permission levels). In one instance, the unbinding of production materials in the user interface must be authorized by senior operators, and configuring traceability rules is the exclusive authority of process personnel. That is, the production material unbinding function on the user interface is used when there is an error in the binding of key materials other than the main material. A senior operator, such as a production line team leader, must enter a password or switch login information to unbind. Ordinary operators do not have the authority to unbind materials to prevent misoperation.

[0106] During operation, when the traceability device determines whether the current process meets the scanning requirements, that is, when production materials have arrived at the designated location, it prompts the user to scan the code through the second user interaction device, and displays the second scanning prompt on the second user interaction device. Based on the prompt, the operator uses a third scanning device to identify the identification information on the production materials of the corresponding product. The identification information is sent to the user interaction device for display and simultaneously transmitted to the traceability device for automatic entry. The traceability device then performs error prevention and records the information. Ultimately, the control device controls other production equipment to execute the next action based on the processing results fed back by the traceability device.

[0107] Furthermore, in step S206, the user interaction device determines whether it is necessary to re-scan the code based on the feedback result. If it is determined that it is necessary to re-scan the code, the user interaction device decodes the production material according to the unbinding information received by the authority, and specifies the new production material (corresponding to the binding information) according to the binding information. Figure 5 In step S308, the operator operates the second user interaction device to re-scan the code), and jumps to step S302. That is, when the second user interaction device determines that the code needs to be re-scanned, the operator unbinds the material on the second user interaction device according to the authority, replaces the production material, and re-scans the code.

[0108] In this embodiment, when the production materials reach the designated location, the tablet enters the autonomous scanning mode. This method is suitable for scenarios where the scanning position is flexible and it is difficult to combine with tooling for fixed scanning. It does not require waiting for control device signals and can perform scanning and identification at any time according to the production process.

[0109] In actual applications, the three scanning modes are suitable for different devices and scanning needs. Different selection and configuration can be made according to actual conditions, which greatly improves the flexibility and accuracy of scanning: 1) In the device-autonomous scanning mode, the control device will automatically trigger the first scanning device to scan the identification information on the production material based on the detected material situation; 2) In the device-triggered tablet scanning mode, the control device will send a code reading signal to the traceability device after detecting that the material is in place. The traceability device will then prompt the scanning information through the tablet (the first user interaction device). The operator uses the scanning device to identify the identification information on the corresponding production material according to the prompt information; 3) In the tablet scanning mode that does not require triggering, the operator controls the third scanning device directly or through a trigger device to scan the code. Among them, the device-triggered tablet scanning mode and the tablet-autonomous scanning mode are not restricted by the production line layout and the degree of automation. They are suitable for production links with more manual intervention or temporary traceability needs, such as the need to install one or more key material stations.

[0110] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
