Description

Technical Field

[0001] The present application relates to the field of automated production systems, and in particular to a linear motor device and an automated production system. Background Art

[0002] In recent years, linear motor technology has become increasingly popular in automated production systems due to its advantages of high speed, high precision, and flexible configuration. In a typical linear motor application, stator modules are sequentially spliced along the conveying direction to form a stator line, while the mover modules move along the stator line, enabling the mover modules to transport items.

[0003] Each mover module can be independently controlled by the control system. In order to be able to identify each mover module, an identification information will be randomly generated by a computer program and assigned to the mover module when the mover module is started. It will be used as the mover identification, so that the mover modules can be distinguished according to the identification information and the relevant information of each mover module can be stored to facilitate the movement control of each mover module.

[0004] However, there are situations where the identification information of the mover module is reallocated. The reallocation of identification information causes the mover identification to change, making it impossible to accurately obtain the historical information of the mover module, that is, the historical information related to the mover module is lost, and the subsequent movement travel of the mover module cannot be determined, requiring manual intervention, which affects the transmission efficiency. Utility Model Content

[0029] To make the features and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In the description of this application, it should be noted that, unless otherwise expressly specified and limited, "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "and / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0031] In automated production systems, linear motor technology is widely used due to its advantages of high speed, high precision, and flexible configuration. Typically, linear motor equipment consists of multiple stator modules spliced sequentially along the conveying direction to form a stator line, while the mover modules move along the stator line to achieve efficient transportation of items. Each mover module can be independently controlled, and different mover modules can perform different tasks at the same time, such as at least one of loading, processing, and unloading tasks. When the mover module starts, an identification information is randomly generated and set as the mover module's mover identification. This is used to distinguish and identify each mover module and manage its related operating information for precise movement control.

[0032] While linear motors offer excellent performance in many areas, existing technologies still have some shortcomings. For example, because identification information is randomly generated, once a mover module is reassigned, its historical information cannot be accurately linked. This results in loss of historical information, hindering the planning and control of the mover module's subsequent travel. This necessitates manual intervention to reconfigure or adjust the travel of the mover module, resulting in lower transmission efficiency.

[0033] For example, Figure 1 As shown, the first randomly generated ID1 is set as the mover identification of the mover module 1, and the relevant information of the mover module 1 is stored in the storage area corresponding to ID1. Later, after the event of setting the mover identification again is triggered, the second randomly generated ID2 is set as the mover identification of the mover module 1, where ID1 and ID2 are different identification information. Since the mover identification of the mover module 1 has changed, the storage area of the relevant information of the mover module 1 has changed, resulting in the inability to obtain the information stored in the storage area corresponding to ID1 for the mover module 1. Even if ID2 has been assigned to other mover modules, the information about other mover modules in the storage area corresponding to ID2 may be used as the information of the mover module 1, resulting in the acquisition of incorrect mover module related information, thereby performing incorrect movement control on the mover, resulting in transmission errors.

[0034] Therefore, due to the randomness of the identification information generated in the relevant technology, after the mover identification of the mover module is changed, the historical information of the mover module is lost, and the subsequent movement stroke of the mover module cannot be accurately controlled, requiring manual intervention, which affects the transmission efficiency.

[0035] Based on this, the present application proposes a linear motor device, which sets a physical tag carrying unique and fixed label information on the mover module, and uses a tag identification module deployed along the stator line to identify the mover module to obtain the corresponding label information. Then, the mover identification configuration module sets the label information as the mover identification of the mover module, thereby ensuring that each mover module has a unique and unchanged mover identification, avoiding the information loss problem that may be caused by random assignment of identification information, significantly improving the movement control efficiency of the mover module, and thus improving the transmission efficiency.

[0036] See also Figure 2 , Figure 2 This is a structural diagram of a linear motor device provided in an embodiment of the present application.

[0037] like Figure 2As shown, the linear motor device provided by the embodiment of the present application includes: a stator line 110, with at least one operating device 200 distributed around the stator line 110; a plurality of mover modules 120, each mover module 120 moves along the stator line 110 and passes through the operating device 200, and the mover module 120 is provided with an identifiable physical tag 121, and the physical tag 121 carries unique and fixed tag information; at least one tag identification module 130, deployed along the stator line 110 to identify the physical tag of the mover module 120 in the passage; a mover identification configuration module 140, connected to the tag identification module 130, for setting the tag information obtained by the tag identification module 130 as the mover identification of the mover module 120.

[0038] Specifically, the mover module 120 is the movable portion of the linear motor device, responsible for carrying objects and precisely moving them along the stator filament 110. The stator filament 110 is the fixed portion of the linear motor device, composed of multiple stator modules 111 spliced and assembled along the conveying direction. Both the mover module 120 and the stator filament 110 have magnetic fields, and the interaction between these magnetic fields enables linear motion of the mover module 120 along the stator filament 110.

[0039] For example, the stator module 111 may include an excitation component ( Figure 2 ), the mover module 120 may include a magnetic component ( Figure 2 (not shown). When the excitation component is energized, it generates a magnetic field. As the magnitude and / or direction of the current changes, the magnetic field generated by the excitation component changes. This changing magnetic field interacts with the magnetic components in the mover module 120 to generate thrust acting on the mover module 120, thereby driving the mover module 120 to move along the stator body. The excitation component may include a coil, and the magnetic component may include a permanent magnet or a magnet.

[0040] It can be understood that the above examples are schematic descriptions for the purpose of understanding. In actual operation, it can be determined according to specific circumstances whether the stator module or the mover module includes an excitation component, and whether the stator module or the mover module includes a magnetic component. The embodiments of the present application do not impose specific restrictions on this.

[0041] Optionally, to monitor the movement of the mover module 120, a measurement module can be deployed along the stator line 110. The measurement module can measure the position of the mover module 120 using at least one of optical, electrical, and magnetic methods. For example, the position measurement module can specifically include at least one of a photoelectric sensor, a magnetic field sensor, an image sensor, and a wireless sensor. The measurement module can monitor the position and / or speed of the mover module 120 in real time. Based on the information obtained by the measurement module, the movement state of the mover module 120 can be monitored, thereby adjusting the movement state of the mover module 120.

[0042] In the linear motor device, at least one operating device 200 is distributed around the stator line 110. The operating device 200 is a production device that works in conjunction with the linear motor device in the automated production system and is used to perform various production operations, such as at least one of loading, processing, and unloading operations. For example, in automated production, after the mover module 120 moves to the operating device 200, the operating device 200 will operate the item according to the set process parameters. For example, when the mover module 120 transfers an item to the processing equipment, the processing equipment will perform a processing operation on the item. After the processing equipment completes the processing operation, the mover module 120 continues to transfer the item to the next operating device.

[0043] It should be noted that the above examples are for illustration only, and in actual applications, the types of operating devices are not limited to these.

[0044] In order to avoid the loss of historical information of the mover module 120 and ensure the integrity of the historical information of the mover module 120, each mover module 120 can be provided with an identifiable physical label 121. It can be understood that the physical label 121 is a physical label that can be attached to the mover module 120. The physical label 121 carries unique and fixed label information (for example, a unique and fixed number). The label information of the physical label 121 is used to be set as the mover identification of the mover module 120.

[0045] The physical tag 121 can be identified by the tag identification module 130. The tag identification module 130 is deployed along the stator filament 110. When the mover module 120 moves into the identification range of the tag identification module 130, the tag identification module 130 can identify the tag information of the physical tag 121. It is understood that in actual applications, the tag identification module 130 may include one or more hardware of a wireless sensing unit, a wireless communication unit, and an image acquisition unit, depending on the type of the physical tag 121. This embodiment of the present application does not impose any specific limitations on this.

[0046] The mover identification configuration module 140 is connected to the tag identification module 130 and is used to set the tag information obtained from the tag identification module 130 as the mover identification of the mover module 120. The mover identification can be used to track, control, or manage the mover module 120 in the automated production system. For example, after obtaining the mover identification of the mover module 120, information is stored or retrieved in the storage area corresponding to the mover identification to execute the corresponding task or manage its path.

[0047] It can be understood that, unlike the randomly generated identification information in the related art, the label information carried by the physical tag 121 is unique and fixed. When the event of setting the mover identification again is triggered, the mover identification configuration module 140 will still reset the label information of the physical tag 121 attached to the mover module 120 to the mover identification of the mover module 120, so that the mover identification of the mover module 120 remains unchanged. The historical information of the mover module 120 can still be obtained through the reset mover tag, thereby ensuring the integrity of the relevant information of the mover module 120.

[0048] Exemplarily, the mover module 120 moves along the stator filament 110. When the mover module 120 enters the identification range of the tag identification module 130, the tag identification module 130 reads the tag information of the physical tag 121 of the mover module 120. The tag identification module 130 transmits the acquired tag information to the mover identification configuration module 140, which configures the acquired tag information as the mover identification of the mover module 120. This ensures that the mover module 120 has a unique and fixed mover identification, ensures the integrity of the relevant information of the mover module 120, improves the efficiency of the movement control of the mover module 120, and thus improves the transmission efficiency.

[0049] In some embodiments, the physical tag includes a visual identification tag and / or an electronic identification tag.

[0050] A visual identification label is a physical label that can be identified using visual analysis technology. It consists of visual elements and can be printed, spray-painted, or otherwise formed on a blank label sheet. For example, the visual elements may include one or a combination of graphics, patterns, and characters. Optionally, the visual identification label can be identified using an image acquisition unit.

[0051] An electronic identification tag is a physical tag that can be identified through electronic signal analysis technology. It may contain a chip, antenna, or other electronic components for storing and transmitting information. Electronic identification tags can be identified through radio waves, magnetic fields, or other methods. Alternatively, electronic identification tags can be identified using wireless sensing units and / or wireless communication units.

[0052] In some embodiments, the physical tag may include one or more of an RFID tag, an NFC tag, a QR code, and a barcode.

[0053] Exemplary, with reference to Figure 2The physical tag 121 may include a barcode, and accordingly, the tag identification module 130 may include a scanner or camera for barcode identification. The physical tag 121 may include a QR code, and accordingly, the tag identification module 130 may include a scanner or camera for QR code identification. The physical tag 121 may include an RFID tag, and accordingly, the tag identification module 130 may include an RFID reader / writer. The physical tag 121 may be an NFC tag, and accordingly, the tag identification module 130 may include an NFC reader / writer.

[0054] Optionally, a combination of one or more of an RFID tag, an NFC tag, a QR code, and a barcode forms the physical tag of the mover module. For example, the physical tag of the mover module can be obtained by combining a QR code and an RFID tag. The QR code and the RFID tag carry the same tag information. As long as the tag recognition module can read at least one of the QR code and the RFID tag, the tag information corresponding to the mover module can be obtained. In this way, the physical tag of the mover module can adapt to multiple types of tag recognition methods, increasing the applicability of the physical tag of the mover module.

[0055] In some embodiments, the physical tag may be located on the surface of the mover module or embedded inside the mover module, and the tag identification module may be located on the surface of the stator wire or embedded inside the stator wire.

[0056] Specifically, a physical label can be provided on the surface of the mover module, where the physical label is directly exposed to the outside and easily identified by the label recognition module. For example, a visual identification label can be provided on the surface of the mover module. The physical label can be provided on the surface of the mover module by gluing, welding, screwing, or other methods.

[0057] Furthermore, when the physical label is provided on the surface of the mover module, the physical label may be a detachable label, so that after the physical label is damaged, the damaged physical label can be quickly removed, thereby speeding up repairs.

[0058] Physical tags can be embedded within the mover module, providing better protection for the physical tag and reducing the probability of damage. For example, an electronic identification tag can be embedded within the mover module, allowing the object to penetrate the mover module using radio waves or magnetic fields and be identified by the tag identification module.

[0059] The label identification module can be set on the surface of the stator wire body, so that it can directly face the physical label of the actuator module, quickly identify the physical label, and facilitate the installation and maintenance of the label identification module. For example, the position of the label identification module relative to the stator wire body can be quickly changed according to needs.

[0060] The tag identification module can be embedded within the stator, reducing the combined space occupied by the stator and tag identification module, thereby improving the hardware integration of the linear motor device. This is particularly true in industrial environments requiring dust and water resistance, where embedding the tag identification module within the stator allows for better adaptation to harsh operating conditions.

[0061] In some embodiments, a accommodating space is formed between the stator wire body and the mover module, the physical label is located on the side of the mover module close to the accommodating space, and the label identification module is located on the side of the stator wire body close to the accommodating space and opposite to the physical label, so that the overall volume of the linear motor device can be reduced.

[0062] For example, Figure 3 As shown, the mover module ( Figure 3 Not shown in the figure) includes a magnetic component 122 and a placement component 123, a stator body ( Figure 3 The stator body (not shown) includes an excitation component 112 and a base 113. The magnetic component 122 is loosely matched with the excitation component 112 of the stator body. When alternating current is applied to the excitation component 112 of the stator body, a changing magnetic field is generated. The magnetic component 122 is magnetically coupled with the energized excitation component 112 to generate thrust. The magnetic component 122 moves under the action of the thrust, thereby driving the placement component 123 connected thereto to move relative to the stator body.

[0063] In addition, the mover module further includes a first guide structure 124 and a second guide structure 125, which are respectively connected to the placement member 123. The stator line body further includes a third guide structure 114 that is slidably matched with the first guide structure 124, and a fourth guide structure 115 that is slidably matched with the second guide structure 125. The third guide structure 114 and the fourth guide structure 115 are also respectively connected to the base 113. Thus, one or more accommodating spaces (such as Figure 3 A physical tag 121 is provided on one side of the mover module near the accommodating space 300 , and a tag identification module 130 is provided on one side of the stator body near the accommodating space 300 . The tag identification module 130 is arranged opposite to the physical tag 121 .

[0064] It should be noted that Figure 3 The positions of the tag identification module 130 and the physical tag 121 are only examples. Those skilled in the art can adjust the specific installation positions of the tag identification module and the physical tag according to actual needs, and will not be listed here one by one.

[0065] In some embodiments, the label identification module can be set upstream of the first operating device in the path of the moving sub-module, wherein the upstream of the operating device can be understood as a position before the operating device along the conveying direction. In other words, the moving sub-module will first pass through the upstream of the operating device before reaching the operating device during the movement process; or, the label identification module is set according to the starting operating position of the first operating device in the path of the moving sub-module.

[0066] For example, Figure 4 As shown, in the automated production system, at least one operating device (such as Figure 4 Two operating devices are shown in the figure, namely, operating device 200-1 and operating device 200-2); the moving submodule 120 moves along the stator line 110 and passes through the operating device 200-1 and the operating device 200-2 in sequence. The tag identification module 130 is set upstream of the first operating device on the moving path of the moving submodule 120, that is, upstream of the operating device 200-1. When the moving submodule 120 moves along the stator line 110, the moving submodule 120 first passes through the tag identification module 130, and the tag identification module 130 reads the physical tag ( Figure 4 (not shown) and then the moving module 120 continues to move and interacts with the operating device 200-1.

[0067] From the above, it can be seen that by setting the label identification module upstream of the first operating device, the label information corresponding to the mover module can be obtained before the mover module reaches the operating device, thereby confirming the mover identification of the mover module in advance and tracing the historical information of the mover module to control the subsequent movement stroke of the mover module.

[0068] In addition, the installation position of the tag identification module can be set according to the operating range of the first operating device. For example, the tag identification module can be set at the starting operating position of the first operating device (that is, the tag identification module overlaps with the starting operating position of the first operating device), or the tag identification module can be set around the part of the stator line body relative to the starting operating position according to the starting operating position of the first operating device, specifically above, below or to the side of the part of the stator line body relative to the starting operating position, to ensure that the tag information can be synchronously obtained when the mover module and the first operating device begin to interact and cooperate, thereby confirming the mover identification of the mover module and tracing the historical information of the mover module to control the subsequent movement of the mover module.

[0069] In practice, when the linear motor device loses power, all electrical components lose power and are unable to monitor the position and status of the mover modules. Upon restart, the linear motor device loses its previously recorded mover module identifiers. To ensure that the tag information for each mover module can be retrieved after the linear motor device is powered off and restarted, a tag identification module can be deployed upstream of each operating device. Alternatively, the tag identification module can be deployed based on the starting operating position of each operating device.

[0070] For example, Figure 5 As shown, in the automated production system, at least one operating device (such as Figure 5 Two operating devices are shown, namely operating device 200-1 and operating device 200-2); the moving module 120 moves along the stator line 110 and passes through the operating device 200-1 and the operating device 200-2 in sequence. Figure 5 Two tag identification modules are shown in FIG. 1 , namely, the tag identification module 130-1 and the tag identification module 130-2. The tag identification module 130-1 is set upstream of each operating device on the moving path of the moving sub-module 120, that is, the tag identification module 130-1 is set upstream of the operating device 200-1, and the tag identification module 130-2 is set upstream of the operating device 200-2. When the moving sub-module 120 moves along the stator line 110, the moving sub-module 120 first passes the tag identification module 130-1, and the tag identification module 130-1 can read the physical tag ( Figure 5 The moving module 120 then continues to move and interact with the operating device 200-1. Alternatively, the moving module 120 first passes through the tag identification module 130-2, which can read the information of the physical tag of the moving module 120. The moving module 120 then continues to move and interact with the operating device 200-2.

[0071] From the above, it can be seen that by setting the tag identification module upstream of each operating device, the tag information corresponding to the mover module can be obtained before the mover module reaches the operating device. Even if the linear motor device stops and restarts, the mover module loses the mover identification configured based on the tag information, and the tag information corresponding to the mover module can be re-identified and obtained before the mover module enters any operating device, thereby confirming the mover identification of the mover module in advance and tracing the historical information of the mover module to control the subsequent movement stroke of the mover module.

[0072] In addition, the installation position of the tag identification module can be set according to the operating range of each operating device. For example, the tag identification module can be set at the starting operating position of the operating device (that is, the tag identification module overlaps with the starting operating position of the operating device), or the tag identification module can be set around the part of the stator line body relative to the starting operating position according to the starting operating position of the operating device, specifically above, below or to the side of the part of the stator line body relative to the starting operating position, to ensure that the tag information can be synchronously obtained when the mover module and the operating device start to interact and cooperate, thereby confirming the mover identification of the mover module and tracing the historical information of the mover module to control the subsequent movement of the mover module.

[0073] As mentioned above, the stator filament can be formed by sequentially splicing a plurality of stator modules along the conveying direction, and the stator modules are in a straight line or arc shape along the conveying direction. Figure 6 As shown in (a) in FIG. 1 , the shape formed by the stator module along the conveying direction may be a straight line shape; or Figure 6 As shown in (b) , the shape formed by the stator module along the conveying direction may be an arc shape.

[0074] It can be understood that, depending on the splicing of the stator modules, in terms of shape, a closed-shaped stator wire body can be spliced, such as a circular stator wire body, a runway-shaped stator wire body, a square-circular stator wire body, etc.; or, a non-closed-shaped stator wire body can be spliced, such as an S-shaped stator wire body, a straight-line stator wire body, a C-shaped stator wire body, etc.

[0075] In specific implementations, for a single non-closed stator filament or multiple stator filaments with spaced-apart shapes, the linear motor device requires a transfer mechanism to transfer the mover module from one end of the stator filament to the other end of the stator filament, or to transfer the mover module from one stator filament to another. Optionally, the transfer mechanism can use mechanical transmission components (such as one or more of a conveyor belt component, a chain component, and a telescopic component) to transfer the mover module, which is combined with the stator filament to form a mixed conveyor filament.

[0076] For example, two stator assemblies of non-closed shapes are horizontally connected by a conveyor belt component of a transfer mechanism to form a mixed conveyor assembly. For another example, two stator assemblies of non-closed shapes are vertically connected by a telescopic component of a transfer mechanism to form a mixed conveyor assembly.

[0077] Generally speaking, the transfer mechanism does not have a positioning function. When the transfer mechanism transfers the moving sub-module, it cannot provide the position information of the moving sub-module. At this time, the moving sub-module is in a tracking blind spot. When the moving sub-module re-enters the original stator line or the new stator line through the transfer mechanism, the linear motor device will regard the moving sub-module as a new tracking object and needs to re-set the moving sub-identity for it, which triggers the event of setting the moving sub-identity again. As described in the previous relevant section, the existing randomly assigned identification information may cause information loss problems.

[0078] While it's possible to reduce tracking blind spots by deploying positioning modules in the transfer mechanism, increasing the transfer distance requires more positioning modules or more positioning areas, significantly increasing hardware costs and computational complexity. Therefore, a solution that balances hardware costs and actuator identification efficiency is needed.

[0079] In some embodiments, the tag identification module is deployed in correspondence with the end of the stator body that is connected to the transfer mechanism; and / or, the tag identification module is deployed in correspondence with the transfer mechanism. Figure 7 As shown, the linear motor device may further include a transfer mechanism 150, the transfer mechanism 150 and the stator line body ( Figure 7 The two ends (not marked) Figure 7 110-a and 110-b) are connected to transfer the submodule 120 at both ends of the stator body. The transfer mechanism 150 can specifically include a conveyor belt component ( Figure 7 Not marked), the tag identification module 130 can be deployed according to the end of the stator body connected to the transfer mechanism 150, specifically as follows Figure 7 As shown, the tag identification module 130 is disposed around the end portion 110 - b of the stator wire body.

[0080] For example, Figure 8 As shown, the linear motor device may further include a transfer mechanism 150, which is connected to the stator line body 110-1 and the stator line body 110-2 respectively, and is used to transfer the submodule 120 between the stator line body 110-1 and the stator line body 110-2; the transfer mechanism 150 may specifically include a conveyor belt component and a telescopic component ( Figure 8 The tag identification module 130 can be deployed according to the corresponding transfer mechanism 150, specifically as follows Figure 8 As shown, the tag identification module 130 is deployed around the transfer mechanism 150 .

[0081] From the above, it can be seen that when the mover module moves along the hybrid conveyor line, the label information carried by the mover module can be identified by deploying the label identification module around the hybrid conveyor line. When the mover module re-enters the stator line, it can be ensured that the mover identification of the mover module has been reset. In this way, tracking blind spots can be avoided. Compared with deploying the positioning module, deploying the label identification module is not affected by the transfer distance, so it can take into account the hardware cost and mover identification efficiency requirements.

[0082] Optionally, the tag identification module can be deployed according to the end of the mover module re-entering the stator line or the end of the mover module moving out of the transfer mechanism to identify the tag information of the mover module re-entering the stator line or moving out of the transfer mechanism; or, the tag identification module can also be deployed according to the end of the mover module moving out of the stator line or the end of the mover module entering the transfer mechanism to identify the tag information of the mover module entering the transfer mechanism or moving out of the stator line.

[0083] In some embodiments, the tag identification module may be fixedly connected to the transfer mechanism; and / or, the tag identification module may be independently provided relative to the transfer mechanism.

[0084] Optionally, the tag identification module can be directly or indirectly fixedly connected to the transfer mechanism. Further, the tag identification module can be directly or indirectly fixedly connected to the mechanical transmission component of the transfer mechanism. Regardless of whether the transfer mechanism transfers the moving submodule, the tag identification module remains linked to the transfer mechanism. The fixed connection method can ensure that after the moving submodule enters the transfer mechanism, the tag identification module is linked to the moving submodule through the transfer mechanism, and identifies the physical tag of the moving submodule during its movement, thereby improving the efficiency of the moving submodule transfer.

[0085] Optionally, the tag recognition module can be independently located from the transfer mechanism. This ensures that the tag recognition module remains in its original position even when the transfer mechanism relocates the submodule. This independent configuration allows the tag recognition module to perform tag recognition at a fixed location around the transfer mechanism, preventing interference from the transfer mechanism and improving the efficiency of physical tag recognition.

[0086] In some embodiments, as Figure 9 As shown, the linear motor device includes a movement control device 160 , and the mover identification configuration module 140 is provided in the movement control device 160 .

[0087] Specifically, the mobile control device 160 is a control unit in the linear motor device, which is responsible for controlling the movement and managing the movement stroke of the mover module 120, and ensuring that the mover module 120 cooperates with the operating device during the movement along the stator line 110. The mobile control device 160 can independently complete the basic motion control and device interaction tasks of the mover module, ensuring real-time performance and response speed. In this embodiment, the mover identification configuration module 140 is provided in the mobile control device 160. It can be understood that the mover identification configuration module 140 can be located inside the mobile control device 160 and regarded as a part of the mobile control device 160; it can also be connected to the mobile control device 160 as an external component. The mobile control device 160 is responsible for setting the tag information obtained from the tag identification module 130 as the mover identification of the mover module 120.

[0088] In some embodiments, as Figure 10 As shown, the linear motor device includes a movement control device 160 and a host device 170 . The host device 170 is connected to the movement control device 160 , and the mover identification configuration module 140 is provided on the host device 170 .

[0089] Specifically, the host device 170 serves as the high-level management and coordination unit in the linear motor equipment, responsible for communicating and coordinating with the multiple motion control devices 160. The host device 170 can perform global task allocation and monitoring management for the entire linear motor system. The host device 170 is responsible for receiving status information from the multiple mover modules 120 and the motion control devices 160 and assigning different tasks to each mover module 120 based on production plans and requirements. Communication with the motion control devices 160 ensures task coordination between the mover modules 120, preventing conflicts and avoiding waste of resources. The host device 170 can be a PC (Personal Computer) or a PLC (Programmable Logic Controller). In this embodiment, the mover identification configuration module 140 is disposed within the host device 170. This can be understood as the mover identification configuration module 140 being internal to the host device 170 and considered part of the host device 170, or as an external component connected to the host device 170. The host device 170 is responsible for setting the tag information obtained from the tag identification module 130 as the mover identification of the mover module 120 .

[0090] In an embodiment of the present application, a physical tag carrying unique and fixed tag information is provided on the mover module, so that a tag identification module deployed along the stator line can be used to identify the mover module and obtain the corresponding tag information. A mover identification configuration module is connected to the tag identification module to assign a mover identification to the mover module based on the obtained tag information, ensuring that each mover module has a unique and unchanging mover identification, avoiding the information loss problem that may occur due to dynamic identification assignment, significantly improving the movement control efficiency of the mover module, and thus ensuring transmission efficiency.
