[0059] See also Figure 1 , Figure 1 : is a flow chart of a marking method provided in an embodiment of the present application. The marking method includes:

[0060] S11, in response to a user's marking request for a product to be marked, generating a first pickup instruction according to the marking request, wherein the first pickup instruction includes basic product information of the product to be marked, a current location of the product, and a preset marking location;

[0061] S12, sending a first picking instruction to the picking robot, so that the picking robot clamps the product to be marked located at the current position of the product onto the servo marking tooling according to the first picking instruction;

[0062] S13. When it is detected that the servo marking tool has a product to be marked and the servo marking tool is located at a preset marking position, a marking instruction is generated according to the basic product information of the product to be marked in the first pickup instruction, and the marking instruction is sent to the marking machine, so that the marking machine marks the product to be marked according to the marking instruction.

[0063] It should be noted that, in this embodiment, the execution entity may be a terminal device such as a controller or a server. For example, in a die-casting product production system, the entity executing the marking method may be a programmable logic control unit (PLC control unit), and no specific limitation is made to this.

[0064] It should be noted that the product to be marked is a product that needs to be marked by engraving or spraying. In the die-cast product production system, the product to be marked is usually a die-cast product that needs to be marked. A marking request is a request initiated by a user to mark the product to be marked, wherein the marking request includes the basic product information of the product to be marked (such as basic attributes, serial number information, etc.), the current location of the product, and the preset marking position for marking. The marking request can be initiated by the user through the marking request button on the production line, or by the user clicking on the user interface, and there is no specific limitation on this.

[0065] The first pickup instruction is an instruction generated based on the marking request initiated by the user, which is used to instruct the pickup robot, servo marking tooling, etc. to perform a series of operations such as picking up and moving. According to the content in the marking request, the first pickup instruction also includes the basic product information of the product to be marked, the current position of the product, and the preset marking position. Among them, the current position of the product is the actual position of the product to be marked in the production line, through which the pickup robot can accurately find and clamp the product. The preset marking position is the preset position on the marking workbench where the product to be marked should be located when the marking operation is performed on the product to be marked. This position is preset according to the design of the product and the actual marking requirements.

[0066] The pickup robot is an automated mechanical device that can automatically grip and carry objects. It can grab and transfer objects accurately and quickly. The servo marking fixture is a fixture used to place and fix the products to be marked so that the products to be marked can remain stable during the marking process.

[0067] The marking instruction is an instruction generated according to the basic product information of the product to be marked in the first instruction and used to instruct the marking machine to mark. The marking machine is a device for marking and printing products, such as a laser marking machine, an inkjet printer, etc. In this embodiment, the marking machine is mainly used to mark, encode and record die-cast products, so as to facilitate the subsequent tracking and management of die-cast products.

[0068] Specifically, when a user issues a marking request for a product to be marked, the system generates a first pickup instruction based on the information about the product to be marked in the marking request. Afterwards, the first pickup instruction is sent to the pickup robot. After receiving the first pickup instruction, the pickup robot moves to the current position of the product according to the information in the first pickup instruction, and clamps the product to be marked at the current position of the product onto the servo marking tooling. When it is detected that the product to be marked is placed on the servo marking tooling, and the servo marking tooling is located at the preset marking position, the system generates a marking instruction based on the basic product information of the product to be marked in the first pickup instruction; then, the marking instruction is sent to the marking machine, so that the marking machine marks the product to be marked according to the marking instruction. The marking method realizes the automated picking, handling and marking of the product to be marked, thereby improving the efficiency and accuracy of the marking process.

[0069] It should be noted that the marking instruction includes a marking code automatically generated by the system, which contains the basic product information (basic attributes or serial number information) of the product to be marked. By marking the marking code on the product to be marked, subsequent tracking and management of the product are facilitated.

[0070] It can be understood that the marking method provided in this embodiment generates a first pickup instruction according to the marking request in response to the user's marking request for the product to be marked, wherein the first pickup instruction includes the basic product information of the product to be marked, the current position of the product and the preset marking position; then, the first pickup instruction is sent to the pickup robot, so that the pickup robot clamps the product to be marked at the current position of the product to be marked onto the servo marking fixture according to the first pickup instruction; when it is detected that the servo marking fixture has the product to be marked and the servo marking fixture is located at the preset marking position, a marking instruction is generated according to the basic product information of the product to be marked in the first pickup instruction, and the marking instruction is sent to the marking machine, so that the marking machine marks the product to be marked according to the marking instruction. The marking method realizes the automatic marking of die-cast products, thereby improving the efficiency and accuracy of marking die-cast products.

[0071] In a possible implementation, the first pickup instruction includes a preset placement location;

[0072] Before sending the first pickup instruction to the pickup robot, the marking method includes:

[0073] The first picking instruction is sent to the servo positioning device, so that the servo positioning device moves the servo marking tool from the current position of the tool to the preset placement position according to the first picking instruction.

[0074] It should be noted that before the pickup robot places the product to be marked on the servo marking tooling, the servo marking tooling may not be at the preset placement position of the marking workbench but at any position of the marking workbench. At this time, it is necessary to send the first pickup instruction to the servo positioning device, and the servo positioning device moves the servo marking tooling from the current position of the tooling to the preset placement position according to the first pickup instruction, so that the servo marking tooling is on standby at the preset placement position. Then, after the servo marking tooling is at the preset placement position, the system sends the first pickup instruction to the pickup robot, and the pickup robot clamps the product to be marked at the current position of the product onto the servo marking tooling.

[0075] It should be noted that the preset placement position is a position pre-set on the marking workbench for the pickup robot to place the product on the servo marking tooling. Usually this position is the origin position of the marking workbench. Generally, in order to facilitate automated operation, this position is fixed; sometimes, for marking needs, this position may not be fixed. In this embodiment, the preset placement position and the preset marking position may be the same or different, and are set according to actual conditions. The servo positioning device is an actuator that can accurately control the position of the servo marking tooling. The servo positioning device can move the servo marking tooling to a specified position in combination with the received pickup instruction, such as a preset placement position, a preset marking position, etc.

[0076] It should be understood that the servo positioning device can make the position of the servo marking tooling accurately positioned with minimal deviation, thereby further improving the automation level of marking and making the entire marking process more flexible and efficient.

[0077] In a possible implementation, after the picking robot clamps the product to be marked located at the current position of the product onto the servo marking tooling according to the first picking instruction, the marking method includes:

[0078] When it is detected that the servo marking tool has a product to be marked and is located at a preset placement position, a first movement instruction is sent to the servo positioning device, so that the servo positioning device moves the servo marking tool from the preset placement position to the preset marking position according to the first movement instruction.

[0079] Specifically, when the picking robot successfully places the product to be marked on the servo marking tooling, and the servo marking tooling is already in the preset placement position, the system will detect this state through the product detection electric eye and send a first movement instruction to the servo positioning device; after receiving the first movement instruction, the servo positioning device controls the movement of the servo marking tooling, and moves the servo marking tooling from the preset placement position to the preset marking position. The first movement instruction is an instruction for instructing the servo positioning device to control the movement of the servo marking tooling.

[0080] It should be understood that the marking method of this embodiment can ensure that the servo marking tool moves to the correct position, so that the product to be marked can be marked at the correct position, further improving the automation level, accuracy and efficiency of marking.

[0081] In a possible implementation, after the marking machine marks the product to be marked according to the marking instruction, the marking method includes:

[0082] Generate a second pickup instruction according to the marking completion information sent by the marking machine; wherein the second pickup instruction includes basic product information of the product to be marked and a preset pickup location;

[0083] The second picking-up instruction is sent to the picking-up robot, so that the picking-up robot clamps the marked product to be marked to the next process according to the second picking-up instruction.

[0084] It should be noted that the marking completion information is a signal sent by the marking machine to the system after completing the marking operation on the product to be marked. The signal is used to indicate that the marking operation has been completed. The second pickup instruction is an instruction for instructing the pickup robot to clamp the marked product to be marked from the servo marking tooling and transport it to the next process. The second pickup instruction includes the basic product information and the preset pickup position of the product to be marked. The preset pickup position is a pre-set position on the marking workbench that is convenient for the pickup robot to clamp the product from the servo marking tooling. Usually, in order to facilitate automated operation, this position is fixed; sometimes, for marking requirements, this position may not be fixed.

[0085] Specifically, when the marking machine completes the marking operation on the product to be marked, the marking machine sends a marking completion message to the system. After receiving the marking completion message, the system generates a second pickup instruction according to the marking completion message, and then sends the second pickup instruction to the pickup robot. After receiving the second pickup instruction, the pickup robot clamps the marked product to be marked on the servo marking tooling at the preset pickup position to the next process for subsequent processing.

[0086] In a possible implementation, before sending the second pickup instruction to the pickup robot, the marking method includes:

[0087] The second picking-up instruction is sent to the servo positioning device, so that the servo positioning device moves the servo marking tool from the preset marking position to the preset picking-up position according to the second picking-up instruction.

[0088] It should be noted that since it is not convenient for the picking robot to grip the product at the preset marking position, the second picking instruction needs to be sent to the servo positioning device before sending the second picking instruction to the picking robot; then, after receiving the second picking instruction, the servo positioning device will control the servo marking tooling to move from the preset marking position to the preset picking position to facilitate the picking robot to grip the product to be marked.

[0089] In a possible implementation, during the process in which the servo positioning device moves the servo marking tool from the preset marking position to the preset picking position according to the second picking instruction, the marking method further includes:

[0090] In response to a user's sampling inspection request for a product to be sampled, a sampling inspection instruction is generated according to the sampling inspection request, wherein the sampling inspection instruction includes basic product information and a sampling inspection location of the product to be sampled; the product to be sampled is a product to be marked that has completed marking;

[0091] Sending a sampling inspection instruction to the servo positioning device, so that the servo positioning device moves the servo marking tooling to the sampling inspection position according to the sampling inspection instruction;

[0092] When it is detected that the servo marking tooling is located at the sampling inspection position, the products to be sampled are sampled according to the sampling inspection instruction and the sampling inspection results are generated.

[0093] It should be noted that the sampling request is information sent by the user to request a sampling inspection of the product to be inspected (i.e. the product to be marked after marking). The sampling information includes the basic information of the product to be inspected and the sampling position. The sampling position is the position on the marking workbench where the product to be inspected should be located when the sampling operation is performed on the product to be inspected. The sampling instruction is an instruction for performing a sampling inspection generated based on the sampling request. The sampling instruction contains the basic product information and the sampling position of the product to be inspected. The sampling result is the data obtained after the sampling operation is performed on the product to be inspected. These results may include information such as the qualified or unqualified status of the product, the correctness of the marking code, etc., which is used to verify the correctness of the marking content and the accuracy of the product information.

[0094] Specifically, in the process of the servo positioning device moving the servo marking tooling from the preset marking position to the preset pickup position according to the second pickup instruction, that is, in the process of the product to be marked moving to the preset pickup position after completing marking at the preset marking position, when receiving a random inspection request issued by the user, the system will generate a random inspection instruction based on the information in the request, and send the random inspection instruction to the servo positioning device. At this time, the product to be marked that has completed marking on the servo marking tooling is the product to be inspected; after receiving the random inspection instruction, the servo positioning device moves the servo marking tooling to the random inspection position according to the random inspection instruction, and performs a random inspection on the product to be inspected, thereby obtaining the random inspection result.

[0095] It should be understood that through the random inspection process of the products, the system realizes the integration of automatic marking and automatic random inspection. Moreover, the random inspection operation will not affect the production process of the entire die-casting product production system. Manual random inspection and automatic random inspection can also be carried out at any time during the automatic production process.

[0096] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0125] The servo positioning device 32 is electrically connected to the servo marking tool 36 and is used to receive the first pickup instruction sent by the control unit 31 and move the servo marking tool 36 to a preset marking position according to the first pickup instruction.

[0126] It should be noted that the control system of the marking system 3 adopts the data processing function of the PLC control unit. The integration of the PLC system and the robot control system can effectively improve the coding efficiency and marking accuracy in the production process of die-casting products. Figure 4 As shown, Figure 4 This is a schematic diagram of the position of a marking system in a die-casting product production system provided by an embodiment of the present application. Figure 4 In the marking system 3, the picking robot 33 and the marking workbench 35 are integrated in the periphery of the die-casting unit in the die-casting product production system. The control unit 31 can be set in the control system of the die-casting product production system, and can also be set in other control systems around the die-casting product production system. The marking system 3 can realize automatic coordination of the marking process and manual sampling positioning, and solve the marking process and sampling test requirements in the marking link of the user's automated production line.

[0127] Optionally, in this embodiment, the control unit 31 is a PLC control unit, which is used to receive the user's marking request, generate instructions, and coordinate and control the entire marking process by establishing communication with various devices. The servo positioning device 32 is an actuator that can accurately control the position of the servo marking tooling. The servo positioning device 32 can move the servo marking tooling 36 to a specified position, such as a preset placement position, a preset marking position, etc., in combination with the received pickup instruction.

[0128] The picking robot 33 is an automated mechanical device that can automatically pick up and carry objects, and can accurately and quickly grab and transfer objects. The marking machine 34 is a device for marking and printing products, such as a laser marking machine, an inkjet printer, etc. In this embodiment, the marking machine is mainly used to mark, encode and record die-cast products, which facilitates the subsequent tracking and management of die-cast products.

[0129] The marking workbench 35 is a fixed work platform for supporting and installing components such as the servo positioning device 32, the marking machine 34 and the servo marking fixture 36. The servo marking fixture 36 is a fixture for placing and fixing the product to be marked so that the product to be marked can remain stable during the marking process. The servo marking fixture 36 can be moved on the marking workbench 35 under the control of the servo positioning device 32. Figure 5 As shown, Figure 5 It is a structural schematic diagram of a marking workbench provided in one embodiment of the present application. Figure 5 In the embodiment, the marking machine 34 is arranged on one side of the marking workbench 35 , and the servo positioning device 32 and the servo marking tool 36 are arranged on the upper surface of the marking workbench 35 .

[0130] Specifically, the control unit 31 establishes a first communication connection with the pickup robot 33 , a second communication connection with the marking machine 34 , and a third communication connection with the servo positioning device 32 . When the user issues a marking request for the product to be marked, the control unit 31 generates a first pickup instruction according to the marking request, wherein the first pickup instruction includes the basic product information of the product to be marked, the current position of the product and the preset marking position; thereafter, the first pickup instruction is sent to the pickup robot 33 and the servo positioning device 32, the pickup robot 33 clamps the product to be marked at the current position of the product onto the servo marking tooling 36 according to the first pickup instruction, and the servo positioning device 32 moves the servo marking tooling 36 to the preset marking position according to the first pickup instruction; then, when the product to be marked is placed on the servo marking tooling 36 and the servo marking tooling 36 is located at the preset marking position, the control unit 31 generates a marking instruction according to the basic product information of the product to be marked in the first pickup instruction, and sends the marking instruction to the marking machine 34, and the marking machine 34 marks the product to be marked according to the marking instruction.

[0131] Furthermore, when the first pickup instruction is sent to the servo positioning device 32, the servo positioning device 32 first moves the servo marking tool 36 from the current position of the tool to the preset placement position according to the first pickup instruction, so that the servo marking tool is on standby at the preset placement position. Then, after the servo marking tool 36 is at the preset placement position, the system sends the first pickup instruction to the pickup robot 33, and the pickup robot 33 clamps the product to be marked at the current position of the product onto the servo marking tool 36. Then, the servo positioning device 32 controls the movement of the servo marking tool 36, and moves the servo marking tool 36 from the preset placement position to the preset marking position.

[0132] Furthermore, after the marking machine 34 completes the marking operation on the product to be marked, the marking machine 34 will send a marking completion message to the control unit 31. After receiving the marking completion message, the control unit 31 will generate a second pickup instruction according to the marking completion message, and then send the second pickup instruction to the pickup robot 33. After receiving the second pickup instruction, the pickup robot 33 will clamp the product to be marked that has been marked on the servo marking tooling 36 located at the preset pickup position to the next process for subsequent processing. At the same time, before sending the second pickup instruction to the pickup robot 33, the second pickup instruction needs to be sent to the servo positioning device 32; then, after receiving the second pickup instruction, the servo positioning device 32 will control the servo marking tooling 36 to move from the preset marking position to the preset pickup position to facilitate the pickup robot to clamp the product to be marked.

[0133] It can be understood that, in this embodiment, the automatic marking of the die-cast products is realized by the marking system 3, thereby improving the efficiency and accuracy of marking the die-cast products.

[0134] In one possible implementation, Figure 6 As shown, Figure 6 A schematic diagram of a display interface of a marking system provided in an embodiment of the present application. Figure 6 , the marking system 3 comprises: a display control unit; wherein,

[0135] The display control unit is used to display the position parameters of the servo marking tool 36, wherein the position parameters include: the current position of the tool, the preset placement position, the preset marking position, the preset pickup position, and the sampling position.

[0136] It should be noted that the display control unit is the interface display part in the marking system 3, which is used to display other parameter information such as the position parameters of the servo marking tool 36 in real time. The position parameters mainly include the current position of the tool, the preset placement position, the preset marking position, the preset pickup position, and the sampling position. Among them, the current position of the tool is the current position of the servo marking tool 36 on the marking workbench 35. The preset placement position is a position pre-set on the marking workbench 35 that is convenient for the pickup robot 33 to place the product on the servo marking tool 36. Usually, the preset placement position is the origin position of the marking workbench 35. Generally, in order to facilitate automated operation, this position is fixed; sometimes, for marking requirements, this position may not be fixed. The preset pickup position is a position pre-set on the marking workbench 35 that is convenient for the pickup robot 33 to clamp the product from the servo marking tool 36. Usually, in order to facilitate automated operation, this position is fixed; sometimes, for marking requirements, this position may not be fixed. The preset marking position is the position where the product to be marked and the servo marking tool 36 should be located on the marking workbench 35 when the product to be marked is marked. The preset marking position is preset according to the design of the product and the actual marking requirements. The sampling inspection position is the position where the product to be sampled and the servo marking tool 36 should be located on the marking workbench 35 when the product to be sampled is sampled.

[0137] It should be understood that the display control unit provides the user with an intuitive and accurate interface for the user to monitor and guide the marking process.

[0138] In a possible implementation, the marking system further includes: a barcode scanner; wherein,

[0139] The barcode scanner is used to perform random inspections on the products to be marked and generate random inspection results.

[0140] It should be noted that a barcode scanner is an automated identification device that reads and identifies product-related information by scanning the marking code on the product. The sampling inspection results are data obtained based on the sampling inspection operation of the barcode scanner. These results may include information such as the qualified or unqualified status of the product and the correctness of the marking code. In this example, the barcode scanner is used to perform sampling inspections on the products to be marked that have been marked to verify the correctness of the marking content and the accuracy of the product information.

[0141] Specifically, in the process of the servo positioning device 32 moving the servo marking tooling 36 from the preset marking position to the preset pickup position according to the second pickup instruction, that is, in the process of the product to be marked moving to the preset pickup position after completing marking at the preset marking position, when receiving a random inspection request issued by the user, the control unit 31 will generate a random inspection instruction based on the information in the request, and send the random inspection instruction to the servo positioning device 32. At this time, the product to be marked that has completed marking on the servo marking tooling 36 is the product to be inspected; after receiving the random inspection instruction, the servo positioning device 32 moves the servo marking tooling 36 to the random inspection position according to the random inspection instruction, and performs a random inspection on the product to be inspected, thereby obtaining a random inspection result.

[0142] It should be noted that the sampling inspection by the barcode scanner can be performed by setting the preset interval time or the preset number of intervals through the control unit 31 to execute the barcode scanning sampling inspection request, thereby realizing automatic sampling inspection. Moreover, the sampling inspection function does not affect the production process of the entire die-casting product production system, and manual sampling inspection and automatic sampling inspection can be carried out at any time during the automatic production process.

[0143] It should be understood that by integrating the barcode scanner into the marking system 3, the efficiency and accuracy of product sampling can be improved, which can help users better control product quality and reduce production costs.
