[0066] Embodiment one

[0067] The present application provides a screw locking management system, with reference to Figure 1 , comprising:

[0068] a production information management system, an intelligent screw counting device, and a screw mounting device.

[0069] Specifically, the production information management system acquires and stores screw locking information of a to-be-locked component. The screw mounting device includes a first communication module, a screw identification device, and a torque sensor; wherein the first communication module is used to communicate with the production information management system to acquire the screw locking information of the to-be-locked component, the screw identification device is used to identify the current installed screw and calculate the number of successfully installed screws, and the torque sensor is used to install the screw position of the screw distribution system according to the preset torque value. The first communication module is also used to send the number of successfully installed screws to the production information management system in real time. The intelligent screw counting device includes a second communication module and a screw distribution system, the second communication module is used to communicate with the production information management system to acquire the screw locking information of the to-be-locked component, and the screw distribution system is used to distribute corresponding screws according to the screw locking information.

[0070] Exemplarily, the following takes the production scene of server production as an example for illustration, and it should be noted that the server production is only an example for illustration, and can also be used for other production and use scenes. The embodiment can obtain the matching relationship between the components and screws in the server complete machine bill of materials through the production information management system, thereby determining the screw model and corresponding screw quantity required by each component of each machine of each order. When the operator scans the product serial number of the equipment and the quality number of the component through the scanning device in the production information management system, the production information management system front end will automatically obtain the matching relationship between the screws and the components stored in the system to display to the operator. By adopting such a technical solution, the production information management system, the intelligent screw counting device and the screw installation device can be combined with each other to realize the intelligentization and management of screw locking, the screw locking information of the to-be-locked component can be provided through the production information management system, the corresponding required screws can be automatically distributed according to the screw locking information through the intelligent screw counting device, and the distributed screws can be accurately installed through the screw installation device, thereby avoiding the missing or incorrect locking of the screws of the to-be-locked component, reducing customer complaints, improving customer experience, improving work efficiency and reducing labor cost.

[0071] In some embodiments, the screw locking information includes at least one of a product serial number of the to-be-locked component, a product serial number of the screw, a screw requirement specification, and a screw requirement quantity, and the screw distribution system is configured to distribute the corresponding screw requirement quantity of the corresponding screw requirement specification according to the product serial number of the to-be-locked component.

[0072] Exemplarily, before the production application is performed, the screw relationship database needs to be established in the production information management system first, that is, the matching relationship between the screws and the components is stored for matching. Each board card requiring screw installation has a product serial number code, and each screw also has a product serial number code. The matching relationship between the product serial number of the to-be-locked component and the corresponding screw product serial number in the bill of materials of the production information management system is developed, the corresponding matching relationship is generated to generate a configuration file and stored in the production information management system, so as to facilitate maintenance and calling, and to facilitate automatic acquisition of the screw model and corresponding screw quantity required by each to-be-locked component of the current board card. The corresponding relationship database is established, and the product serial number and attribute description of the to-be-locked component, the product serial number of the screw, the screw requirement specification, and the corresponding screw requirement quantity are stored.

[0073] For example, after the operator scans the component to be locked, the smart screw counting device can automatically obtain the screw locking information of the component to be locked stored in the production information management system through cooperation with the smart screw counting device and the production information management system. The smart screw counting device can distribute the required number of screws of the corresponding screw specification according to the product serial number of the component to be locked through the screw distribution system. By using such a device, the required number of screws can be provided, thereby avoiding the error of the number and type of screws taken by the operator manually taking the screws from the screw box, and avoiding the wrong locking and missing locking of the screws.

[0074] Specifically, the smart screw counting device includes a second communication module and a screw distribution system. The second communication module is used to communicate with the production information management system to obtain the screw locking information of the component to be locked. The second communication module includes a connection port connected to the production information management system, through which the smart screw counting device can obtain the screw locking information stored and maintained in the production information management system, and distribute the screws according to the obtained screw locking information. A suitable communication protocol (such as Wi-Fi or Bluetooth) can be used to realize data transmission and communication between the production information management system and the smart screw counting device. The screw distribution system is used to distribute the corresponding screws according to the screw locking information. The screw distribution system can accurately distribute a specified number and type of screws according to the screw locking information. The screw distribution system can include an automatic counting device, a distribution mechanism (such as a rotating disc or a vibrating rod), and an output channel through which the distributed screws are guided to the operator.

[0075] In addition, the smart screw counting device can also include a user interface, which includes a display screen and an input device (such as a keyboard or a touch screen), and the input device is used for the operator to input instructions. The display screen is used to display the current state of the smart screw counting device in real time, and the current state includes at least one of the current storage number and type of screws, the screw information being distributed, and the running state of the system.

[0076] In some embodiments, the smart screw counting device further includes a screw detection system for detecting the remaining number of screws distributed by the screw distribution system; the screw detection system is further used to trigger an alarm in response to detecting that the screw installation device has completed installing the screws and there is still a remaining number of distributed screws.

[0077] Specifically, the smart screw counting device further includes a screw detection system, which includes a quantity detection sensor and an alarm system. The quantity detection sensor is used to detect the number of screws in the screw box. If there are still remaining screws in the screw box after the screw distribution is completed and the screw installation device has completed installing the screws, an alarm will be triggered through the alarm system to notify the operator that there may be incomplete assembled screws.

[0078] In some embodiments, the screw installation device comprises a first communication module, a screw identification device, and a torque sensor; wherein the first communication module is used to communicate with the production information management system to obtain the screw locking information of the component to be locked, the screw identification device is used to identify the current installation screw and calculate the number of successfully installed screws, and the torque sensor is used to install the screw distributed by the screw distribution system according to the preset torque value. The first communication module is also used to send the number of successfully installed screws to the production information management system in real time.

[0079] Specifically, referring to Figure 2 , the screw installation device can be an intelligent screwdriver or other screw installation mechanism with the above functions. For example, the intelligent screwdriver comprises a servo motor, a speed changing assembly, and a torque sensor for detecting the reverse torque of the speed changing assembly. One end of the torque sensor is fixedly connected with the speed changing assembly, and the other end of the torque sensor is fixedly connected with the shell. The servo motor is used to drive the speed changing assembly. The shell of the intelligent screwdriver is also provided with a printed circuit board and a screw identification device. The printed circuit board is electrically connected with the screw identification device, the torque sensor, and the servo motor. The printed circuit board is also connected with an external display device. The external display device is used to display at least one of the current torque value, the current screw information, the number of successfully installed screws, and the number of disassembled screws. For example, when the intelligent screwdriver is in operation, the servo motor drives the speed changing assembly, and the speed changing assembly transmits the reaction force to the torque sensor, so that the torque sensor senses the torque and transmits the data to the external display device through the printed circuit board to display the torque parameter in real time. The torque sensor can detect and accurately measure the torque, so as to ensure that the screw is installed in place. If the preset torque deviates, the servo motor output is controlled through the printed circuit board, so that the torque is more accurate and reliable when the screw material is tightened (subsequent training of each material and each model of screw through deep learning can be used to configure and store each model of screw used in each material. When the corresponding screw is identified through the screw identification device, the corresponding torque is matched through the printed circuit board, and the servo motor output is controlled to reach the corresponding torque, so that the torque is more accurate and reliable when the material is tightened). For example, the intelligent screwdriver also comprises a screw suction nozzle, which can quickly take and disassemble the screw. In particular, the screw suction nozzle can also be provided with a screw sensor for identifying screw installation / disassembly, so as to count the number of screw installations and the number of screw disassemblies and return to the screw identification device. In addition, the intelligent screwdriver can also comprise a screw detection camera module for identifying the screw model and the installation condition and returning the screw model and the installation condition to the screw identification device.

[0080] Specifically, the torque sensor can detect and accurately measure the size of the torque, to ensure that the screw is installed in place. The torque sensor can sense the force applied on the screw, and if the set torque value is reached, it can indicate that the screw has been properly positioned. The first communication module can communicate with the production information management system in real time through wireless communication protocols such as Wi-Fi or Bluetooth, obtain the information of the required screw, and report the number of installed / dismantled screws in real time. The screw identification device is used to identify the current installation screw and calculate the number of successfully installed screws. The screw identification device includes a counting device, which can calculate the number of installed / dismantled screws through electronic sensors or encoders. Each time the worker installs or dismantles a screw, the counter will record it. Only when the calculation result (the number of successfully installed screws - the number of dismantled screws) is consistent with the number of required installed screws provided by the bill of materials, the entire operation is considered correct, otherwise the screw installation device will alarm. The screw identification device also includes a screw model identifier, which can determine the model of the screw used through RFID (Radio Frequency Identification) tags, barcodes, or other forms of automatic identification methods. If the identified screw model is inconsistent with the screw attachment information in the production information management system, an alarm will be issued immediately to avoid the possibility of installing the wrong screw. The screw installation device also includes a user interface for inputting related operation information (such as torque setting value, etc.) on the screw installation device side. The user interface in the screw installation device can include a digital keyboard or touch screen to allow workers to input the required torque value, and can also display the screw data currently being used, the operation being performed, and the status of the screw installation device, etc.

[0081] In some embodiments, the torque sensor is also used to measure the actual torque value of the installed screw, and the torque sensor is also used to compare the preset torque value and the actual torque value to determine whether the current screw is installed in place.

[0082] Specifically, the torque sensor can measure the actual torque applied when installing the screw, i.e. the actual torque value. The torque sensor can determine whether the screw is correctly installed in place by comparing the set torque value and the actually measured torque value. Thus, it can detect whether each screw is correctly installed in place, avoiding manual checking by the operator, saving time and effort.

[0083] In some embodiments, if the current screw is not installed in place, the screw installation device is also used to dismantle the current screw that is not installed in place; and the screw identification device is also used to calculate the number of successfully installed screws and the number of dismantled screws.

[0084] Specifically, the screw identification device is used to identify the current installation screw and calculate the number of successfully installed screws and the number of removed screws. The screw identification device includes a counting device that can calculate the number of installed / removed screws through an electronic sensor or an encoder. Each time the worker installs or removes a screw, the counter records it. The screw identification device also includes a screw model identifier that can determine the model of the screw used through an RFID (Radio Frequency Identification) tag, a barcode, or other forms of automatic identification methods. If the identified screw model is inconsistent with the screw locking information in the production information management system, a warning will be issued immediately to avoid the possibility of installing the wrong screw. The screw identification device can report the current installation status (each screw installation success / removal success or installation failure) to the production information management system in real time during the installation process, so that the production information management system can understand the installation information of each screw. In particular, it can also be matched with a visual module to synchronously identify the installation position and installation condition of each screw, so that the production information management system can understand the installation condition of each screw and the installation condition of each installation position. By using such technical means, the number of successfully installed screws and the number of removed screws can be obtained, the current installation status can be reported in real time, and the production information management system can understand the installation condition of each screw, further reducing the possibility of screw locking error and omission.

[0085] In some embodiments, the screw identification device is also used to trigger an alarm in response to detecting that the screw installation device has completed the installation of the screw and the difference between the number of successfully installed screws and the number of removed screws and the screw requirement quantity provided by the bill of materials do not match.

[0086] Specifically, only when the calculation result (the number of successfully installed screws - the number of removed screws) matches the screw requirement quantity provided by the bill of materials, the entire operation is considered to be correct, otherwise the screw installation device will issue an alarm. In order to prompt the operator to check whether there is a reason for missing or locking error when the difference between the number of successfully installed screws and the number of removed screws and the screw requirement quantity do not match, so as to avoid missing or locking error. In particular, it can also be matched with a real-time monitoring and learning system, which can collect and learn data during the screw locking process, such as the actual torque value during each screw tightening operation, and can estimate the preset torque value for the next same model screw tightening through a dynamic feedback algorithm; Similarly, it can also collect the installation condition of each installation position, learn the installation condition prone to missing or locking error, analyze the reason for missing or locking error, and optimize the installation process, so as to better adapt to production demand and environment and improve work efficiency.

[0087] In the embodiment, the production information management system, the intelligent screw counting device and the screw installation device can be combined with each other to realize the intelligentization and management of screw locking, the screw locking information of the to-be-locked component can be provided through the production information management system, the required screws can be automatically distributed according to the screw locking information through the intelligent screw counting device, and the distributed screws can be accurately installed through the screw installation device, so that the missed or wrong locking of the screws of the to-be-locked component can be avoided, customer complaints can be reduced, customer experience can be improved, work efficiency can be improved, and labor cost can be reduced.

[0088] Embodiment two

[0089] Corresponding to the above embodiment, the application further provides a screw locking management method, referring to Figure 3 , the method comprises:

[0090] S1, the production information management system obtains the component information of the current to-be-locked component through a scanning device, and the production information management system matches corresponding screw locking information according to the component information;

[0091] S2, the production information management system sends the screw locking information to the intelligent screw counting device, and the intelligent screw counting device distributes corresponding screws according to the screw locking information;

[0092] S3, the screw installation device obtains the screw locking information sent by the production information management system, and installs corresponding screws according to the screw locking information until the screw installation is completed, and the screw installation device returns the number of successfully installed screws to the production information management system in real time;

[0093] S4, the production information management system judges whether the screw installation device is successfully installed for the current to-be-locked component according to the number of successfully installed screws and the required number of screws, generates a judgment result and returns it to the screw installation device.

[0094] Specifically, before the production application, the screw relationship database needs to be established in the production information management system, that is, the matching relationship between the screws and the components is stored for matching. Each board card that needs to install screws has a product serial number code, and each screw also has a product serial number code. The matching relationship between the product serial number of the to-be-attached component product serial number and the corresponding screw product serial number in the bill of materials of the development production information management system is generated to store the corresponding configuration file in the production information management system for easy maintenance and calling, so as to automatically obtain the screw type required by each to-be-attached component of the current board card and the corresponding screw quantity. The corresponding relationship database is established, and the product serial number and attribute description of the to-be-attached component, the product serial number of the screw, the screw requirement specification, and the corresponding screw requirement quantity are stored. After the operator scans the to-be-attached component, the intelligent screw counting device can automatically obtain the screw attachment information of the to-be-attached component stored in the production information management system through the cooperation of the production information management system and the intelligent screw counting device. The intelligent screw counting device will distribute the corresponding screw quantity of the corresponding screw requirement specification through the screw distribution system according to the product serial number of the to-be-attached component. The operator installs the corresponding screw through the screw installation device according to the screw attachment information until the screw installation is completed. The screw installation device will return the installed screw quantity to the production information management system in real time. The production information management system can judge whether the screw installation device is successfully installed for the current to-be-attached component according to the installed screw quantity and the screw requirement quantity, generate a judgment result, and return it to the screw installation device. By adopting such a technical scheme, the production information management system, the intelligent screw counting device, and the screw installation device can be combined with each other to realize the intelligentization and management of screw attachment. The screw attachment information of the to-be-attached component can be provided through the production information management system, the corresponding required screw can be automatically distributed through the intelligent screw counting device according to the screw attachment information, and the distributed screw can be accurately installed through the screw installation device, thereby avoiding the screw missing or wrong locking of the to-be-attached component, reducing customer complaints, improving customer experience, improving work efficiency, and reducing labor costs.

[0095] In particular, the screw identification device can also identify the currently installed screw and calculate the number of successfully installed screws and the number of removed screws. The screw identification device includes a counting device, which can calculate the number of installed / removed screws through an electronic sensor or an encoder. Each time the worker installs or removes a screw, the counter will record it. Only when the calculation result (the number of successfully installed screws-the number of removed screws) is consistent with the screw requirement quantity provided by the bill of materials, the entire operation is considered to be correct, otherwise the screw installation device will alarm. When the difference between the number of successfully installed screws and the number of removed screws matches the screw requirement quantity, it is judged that the screw installation device is successfully installed for the current to-be-attached component, and the next to-be-attached component can be installed or the installation can be completed.

[0096] The screw locking management method applied to the production information management system comprises the following steps: Figure 4

[0097] 101. Acquire component information of a current component to be locked by a scanning device, and match corresponding screw locking information according to the component information;

[0098] 102. Send the screw locking information to an intelligent screw counting device, so that the intelligent screw counting device distributes corresponding screws;

[0099] 103. Send the screw locking information to a screw installation device, and receive the number of successfully installed screws returned by the screw installation device in real time;

[0100] 104. Judge whether the screw installation device successfully installs the current component to be locked according to the number of successfully installed screws and the number of required screws, generate a judgment result, and return the judgment result to the screw installation device.

[0101] In some embodiments, step 104 comprises:

[0102] In response to detecting that the difference between the number of successfully installed screws and the number of disassembled screws matches the number of required screws, it is judged that the screw installation device successfully installs the current component to be locked, and a successful installation result is returned to the screw installation device.

[0103] ​Specifically, a screw relationship database is established in the production information management system, which can store the matching relationship of screws and components to facilitate matching. Each board card that needs to install screws has a product serial number code, and each screw also has a product serial number code. The matching relationship between the product serial number of the to-be-attached component in the bill of materials in the production information management system and the corresponding screw product serial number is developed, and the corresponding configuration file is stored in the production information management system to facilitate maintenance and calling, and to facilitate automatic acquisition of the screw type required by each to-be-attached component of the current board card and the corresponding screw quantity. The corresponding relationship database is established, which stores the product serial number and attribute description of the to-be-attached component, the product serial number of the screw, the screw requirement specification, and the corresponding screw requirement quantity. In addition, during installation, the current installation state reported by the screw installation device side (such as each screw installation success / dismounting success or installation failure) can be received in real time, and the production information management system can understand the installation information of each screw. According to the number of successfully installed screws and the screw requirement quantity, it is judged whether the screw installation device is successfully installed on the current to-be-attached component, a judgment result is generated and returned to the screw installation device. In particular, considering that there may be individual screw installation failures that need to be dismounted during installation, therefore, the production information management system can also receive the number of dismounted screws. Only when the calculation result (the number of successfully installed screws minus the number of dismounted screws) is consistent with the screw requirement quantity provided by the bill of materials, the entire operation is determined to be correct. If the quantities are consistent, it is judged that the screw installation device is successfully installed on the current to-be-attached component, and the installation success result is returned to the screw installation device. That is, the current to-be-attached component is installed and successfully installed, and the installation of the next to-be-attached component or the end of the installation process can be performed.

[0104] The screw attachment management method applied to the intelligent screw counting device comprises the following steps: Figure 5 , comprising:

[0105] 201, receiving the screw attachment information sent by the production information management system;

[0106] 202, distributing the corresponding screw according to the screw attachment information, so that the screw installation device installs the corresponding screw.

[0107] In some embodiments, the method further comprises:

[0108] 203, detecting the remaining number of distributed screws of the screw distribution system by the screw detection system;

[0109] 204, in response to detecting that the screw installation device has completed installing the screw and there is still a remaining number of distributed screws, the screw detection system triggers an alarm.

[0110] Specifically, the corresponding screw can be distributed according to the screw locking information. The screw distribution system can accurately distribute a specified number and type of screws according to the screw locking information. The screw distribution system can include an automatic counting device, a distribution mechanism (such as a rotating disc or a vibrating rod), and an output channel through which the distributed screws are guided to the workers. If there are remaining screws in the screw box after the screw distribution and the screw installation device finishes installing the screws, an alarm system will trigger an alarm to notify the operator that there may be uninstalled screws.

[0111] The screw locking management method applied to the screw installation device refers to Figure 6 , and includes

[0112] 301. Obtain the screw locking information sent by the production information management system;

[0113] 302. Install the corresponding screw according to the screw locking information until the screw installation is completed, and return the number of successfully installed screws to the production information management system in real time.

[0114] In some embodiments, the method further includes

[0115] 311. Compare the preset torque value and the currently measured actual torque value through the torque sensor to determine whether the current screw is installed in place;

[0116] 312. In response to detecting that the current screw is not installed in place, disassemble the current screw that is not installed in place, and calculate the number of successfully installed screws and the number of disassembled screws in real time.

[0117] In some embodiments, the method further includes

[0118] 313. In response to detecting that the screw installation is completed and the difference between the number of successfully installed screws and the number of disassembled screws does not match the screw demand number, trigger an alarm.

[0119] Specifically, the screw installation device can identify the current screw being installed and calculate the number of successfully installed screws, and report the number of successfully installed screws to the production information management system in real time. The production information management system can obtain the installation information of each screw. The production information management system can determine whether the screw installation device successfully installs the current component to be attached according to the number of successfully installed screws and the number of required screws, generate a determination result, and return the determination result to the screw installation device. In particular, considering that there may be individual screws that fail to be installed and need to be removed during the installation process, the screw installation device calculates and reports the number of successfully installed screws and the number of removed screws in real time, so that the production information management system can also receive the number of removed screws. Only when the calculation result (the number of successfully installed screws minus the number of removed screws) is consistent with the number of required screws provided by the bill of materials, the entire operation is determined to be correct. If the numbers are consistent, the production information management system determines that the screw installation device successfully installs the current component to be attached, and returns the installation success result to the screw installation device. That is, the current component to be attached is installed and successfully installed, and the installation of the next component to be attached or the end of the installation process can be performed.
