[0002] In related technologies, belt conveyors are commonly used to transport workpieces. One side of the belt conveyor is typically equipped with a connecting structure to transfer workpieces from one conveyor line to another. However, when space is limited between the processing station and the conveyor lines, large or complex connecting structures cannot be installed. Summary of the Invention

[0003] The main objective of this application is to provide a conveying mechanism to solve the technical problem in the prior art where the limited space between the conveyor line and the processing station makes it inconvenient to install a connecting mechanism.

[0004] To achieve the above objectives, according to one aspect of this application, a conveying mechanism is provided for conveying a workpiece to be processed, comprising: a first conveyor line extending along a first direction; a processing station disposed on one side of the first conveyor line; and a mover assembly including a driving component and a carrying component, wherein the driving component is disposed on the first conveyor line, a docking station is provided on the first conveyor line, the first conveyor line is magnetically coupled to the driving component to drive the driving component to move to the docking station, and the carrying component is used to carry the workpiece to be processed, and the carrying component is movably disposed on the driving component along a second direction to drive the workpiece to move between the docking station and the processing station; wherein the first direction and the second direction are arranged at an angle.

[0005] Furthermore, the moving part assembly also includes a docking component extending along the second direction, with the driving component and the bearing component respectively disposed on opposite sides of the docking component, and the docking component being movably disposed on at least one of the driving component and the bearing component; when the driving component is in the docking position, at least a portion of the docking component is movably disposed along the second direction to drive the workpiece to be processed to move along the second direction.

[0006] Furthermore, the docking assembly includes a second guide rail and a second slider that are slidably connected. The second guide rail is disposed on the driving component, and the second slider is disposed on the bearing component. One end of the second guide rail is disposed on the first conveyor line. When the moving component is in the docking station, the other end of the second guide rail extends to the processing station, so that the second slider drives the workpiece to be processed to move to the docking station or the processing station.

[0007] Furthermore, a conveying component is provided at the processing station, at least a portion of which is movably arranged along the second direction. When the docking component is in the docking station, the third transmission component docks with the docking component to transport the workpiece to be processed on the docking component to the processing station.

[0008] Furthermore, the length of the workpiece to be processed along the second direction is L1, and the distance between the third transmission assembly and the docking assembly along the second direction is L2, wherein L2 < L1; and / or, the transmission assembly further includes an abutment member, which is disposed at the end of the transmission assembly away from the docking assembly, and along the second direction, the orthographic projection of the abutment member coincides at least partially with the orthographic projection of the bearing member.

[0009] Furthermore, an actuator is provided on the processing station, and a positioning fixture is provided on the bearing component for clamping the workpiece to be processed. At least one clearance groove is provided on the bearing component so that when the bearing component is in the processing station, at least a portion of the actuator extends out of the clearance groove to process the workpiece to be processed.

[0010] Furthermore, the positioning fixture includes multiple main clamping members, which enclose a clamping area for clamping the workpiece to be processed. The projection of the clamping area onto the supporting component in the vertical direction forms a projection area, and at least one clearance groove is provided in the projection area.

[0011] Furthermore, the positioning fixture also includes multiple secondary clamping members, which together form a second clamping area for clamping the workpiece to be processed. The projection of the second clamping area onto the bearing member in the vertical direction forms a second projection area, and at least one clearance groove is provided in the second projection area.

[0012] Furthermore, the actuator includes a lower jet assembly. When the supporting component is in the machining station, the jet nozzle of the lower jet assembly is positioned facing the workpiece. The lower jet assembly is vertically oriented such that at least a portion of the jet nozzle extends out of the clearance groove to jet the workpiece. And / or, the actuator includes an upper jet assembly. The upper jet assembly is vertically oriented above the machining station. When the supporting component is in the machining station, the jet nozzle of the upper jet assembly is positioned facing the workpiece, and the lower jet assembly is positioned below the machining station.

[0013] By applying the technical solution of this application, the collaborative relationship between the first conveyor line and the moving component effectively solves the problem of limited space between the conveyor line and the processing station, making it difficult to install the connecting mechanism in the prior art. Specifically, the first conveyor line extends along the first direction and is provided with a docking station. The driving component drives the carrying component to move to the docking station through magnetic coupling with the first conveyor line, thereby achieving positioning along the first direction. The carrying component, as the direct carrier of the workpiece to be processed, is movably mounted on the driving component along a second direction at an angle to the first direction. This allows the carrying component to replace the traditional connecting structure. After the driving component is positioned at the docking station, the workpiece can be directly transferred from the docking station to the processing station next to the first conveyor line simply by moving the carrying component in the second direction. This breaks through the dependence of the traditional connecting structure on lateral space. Even if the space between the conveyor line and the processing station is limited, seamless transfer can be achieved through the accurate positioning of the driving component and the short-stroke movement of the carrying component, avoiding the problem of the connecting mechanism being unable to be installed or having a complex structure due to insufficient space.

Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figures 1-6 This application provides a conveying mechanism for conveying a workpiece to be processed, comprising: a first conveyor line 100 extending along a first direction; a processing station disposed on one side of the first conveyor line 100; and a mover assembly 200 including a driving component 210 and a carrying component 220. The driving component 210 is disposed on the first conveyor line 100, and a docking station is disposed on the first conveyor line 100. The first conveyor line 100 and the driving component 210 are magnetically coupled to drive the driving component 210 to move to the docking station. The carrying component 220 is used to carry the workpiece to be processed and is movably disposed on the driving component 210 along a second direction to drive the workpiece to be processed to move between the docking station and the processing station. The first direction and the second direction are arranged at an angle.

[0025] The conveying mechanism of this embodiment includes a first conveyor line 100, which extends along a first direction and forms a magnetic coupling relationship with the driving component 210. This enables the driving component 210 to reciprocate along the first conveyor line 100, allowing it to autonomously move to a pre-set docking station on the first conveyor line 100. In the prior art, belt conveyors are used to transport workpieces, while this application uses magnetic coupling between the first conveyor line 100 and the driving component 210 to transport workpieces. Compared with the prior art, this application can achieve higher control precision and make the conveying process more accurate. At the same time, since the magnetic coupling drives directly without intermediate transmission links, the response speed is faster, and the workpiece to be processed can be quickly transported to the docking station, thereby achieving faster conveying. In addition, the bearing component 220 is movably disposed on the driving component 210 along a second direction at an angle to the first direction, allowing the workpiece to be processed to be flexibly transferred between the docking station and the processing station, no longer relying on a fixed connecting mechanism, thus adapting to different spatial layouts and conveying requirements, reflecting the flexibility of the conveying process. A support component 220 is provided on the drive component 210. The support component 220 is used to fix the workpiece to be processed and can move relative to the drive component 210 along a second direction at an angle to the first direction through active movement or a combination of active and passive movement. This allows the workpiece to reciprocate between the docking station and the processing station located on one side of the first conveyor line 100. When the support component 220 moves actively, after the drive component 210 drives the support component 220 to the docking station, the support component 220 and the workpiece on it move actively along the second direction. This allows for a simple and direct transfer from the docking station to the processing station. The control logic is simple, the response is rapid, and it is suitable for short-stroke, high-frequency, and precise positioning scenarios. By combining active and passive movement, the carrying component 220 first actively moves along the second direction to the preset position, and then passively moves under the action of the external structure to continue to transport to the processing station, forming a "relay" transfer. This method can adapt to complex working conditions that require long-distance lateral transmission or linkage with downstream equipment. While ensuring the accurate positioning of the active section, the passive section is used to extend the conveying stroke, thereby improving the overall flexibility and adaptability of the system.

[0026] To address the technical problem in the prior art where the limited space between the processing station and the conveyor line makes it difficult to install large-volume or complex connecting structures when using belt conveyors, this application solves this problem through the collaborative design of the drive component 210 and the carrier component 220. Specifically, the drive component 210 is magnetically coupled to the first conveyor line 100, enabling precise movement to the docking station and achieving positioning in the conveying direction (first direction); the carrier component 220 directly carries the workpiece to be processed and is movably mounted on the drive component 210 along a second direction at an angle to the first direction. Thus, the carrier component 220 completely replaces the traditional independent connecting structure. When the drive component 210 reaches the docking station, no additional robotic arm, pushing device, or transfer mechanism is needed; the workpiece can be directly transferred from the docking station to the side processing station simply by moving the carrier component 220 along the second direction. This integrated design avoids the need to install a separate connecting mechanism in a limited space, effectively solving the installation problem caused by insufficient space. The advantages of this design are as follows: on the one hand, it eliminates the need for a separate connecting structure, making the overall layout more compact and simple, and reducing the complexity and cost of the equipment; on the other hand, due to the high-precision positioning achieved by the magnetic coupling of the drive component 210, coupled with the direct movement and transfer of the load-bearing component 220, the intermediate transmission links are reduced, improving the positioning accuracy and response speed of the conveyor, while ensuring that the workpiece can still be transported efficiently and stably in a narrow space.

[0027] In the above embodiments, the driving component 210 moves the workpiece between two workstations. In some embodiments, the process of the driving component 210 moving the workpiece between two workstations is achieved solely through the active movement of the carrying component 220. For example... Figure 5 As shown, after the carrier component 220 moves to the docking station, the carrier component 220 and the workpiece on it move actively along the second direction, moving from the docking station into the processing station. In other embodiments, the process of the drive component 210 moving the workpiece between the two stations is achieved by a combination of active and passive movement of the carrier component 220. After the drive component 210 is positioned, the carrier component 220 first moves actively along the second direction to a preset position, and then, under the action of the external structure, the carrier component 220 moves passively to continue being transported to the processing station, realizing a "relay" transfer. This is suitable for scenarios requiring long-distance lateral transmission or linkage with downstream equipment, improving the system's flexibility and adaptability.

[0028] In the embodiments of this application, the angle between the first direction and the second direction is 90°. In other embodiments, the angle between the first direction and the second direction may be other angles. The 90° angle between the first direction and the second direction allows the workpiece to be processed to be precisely translated laterally in the vertical second direction by the carrying component 220 while being longitudinally conveyed along the first conveyor line 100. This efficiently and stably completes the positioning transfer from the docking station to the processing station, maximizing the use of space layout, simplifying the mechanical structure, reducing control complexity, and improving the overall system's operating accuracy and reliability. In other embodiments, the angle between the first direction and the second direction may also be set to other angles. This flexible and adjustable design gives the conveying mechanism stronger adaptability, allowing it to be customized according to different production line layouts, equipment space constraints, or process requirements. For example, it can optimize the path and reduce interference in narrow or non-right-angled factory environments, thereby expanding the various feasibility of the conveying mechanism without sacrificing functionality.

[0029] Specifically, the first conveyor line 100 includes multiple stator assemblies 110, each stator assembly 110 including a stator body 111, a first guide rail 112 and an armature winding 113. The stator body 111 is spliced ​​along a first direction, and the first guide rail 112 and the armature winding 113 are both fixedly disposed on the stator body 111 and extend along the first direction. The drive component 210 includes a mover body 211, a first slider 212 and a permanent magnet array 213. The first slider 212 and the permanent magnet array 213 are both disposed on the mover body 211. The first slider 212 is slidably connected to the first guide rail 112, and the armature winding 113 and the permanent magnet array 213 are magnetically coupled to drive the mover assembly 200 to move along the first direction.

[0030] In some embodiments, the first conveyor line 100 is composed of multiple stator assemblies 110 spliced ​​along a first direction. Each stator assembly 110 integrates a stator body 111, a first guide rail 112, and an armature winding 113. The first guide rail 112 and the armature winding 113 are both fixed to the stator body 111 and extend continuously along the first direction. By integrating the first guide rail 112 and the armature winding 113 onto the same stator body 111 and achieving a continuous and uninterrupted extension along the conveying direction, not only is the space between the guide rail and the electromagnetic drive component 210 during the operation of the mover assembly 200 ensured, but also... The stable relationship avoids problems such as poor sliding or uneven magnetic coupling caused by segmented installation errors, and greatly improves the overall smoothness of the system's motion and positioning accuracy. At the same time, this integrated continuous structure simplifies the assembly process, reduces the risk of tolerance accumulation caused by splicing multiple parts, and enhances the system's reliability and maintenance convenience. In addition, the continuous extension of the armature winding 113 can realize stepless electromagnetic excitation along the conveying path, so that the mover assembly 200 can obtain stable and uniform thrust output at any position, thereby supporting high-speed, high-response precise motion control and realizing efficient and stable long-distance linear conveying. The drive component 210 includes a mover body 211, a first slider 212, and a permanent magnet array 213. The first slider 212 is slidably engaged with the first guide rail 112. The permanent magnet array 213 forms a magnetic coupling relationship with the armature windings 113 of each stator assembly 110. When the armature windings 113 are energized, they generate a thrust along the first direction through interaction with the permanent magnet array 213, driving the mover assembly 200 to move smoothly along the first guide rail 112. Since the stator assembly 110 is modularly spliced ​​and each segment has an independent guide rail and winding, the driving force of the entire first conveyor line 100 is evenly distributed and the motion trajectory is continuous, which significantly improves the positioning accuracy and running stability of the mover assembly 200 when migrating between the docking station and the processing station.

[0031] Specifically, the mover assembly 200 further includes a docking assembly 230 extending along the second direction. The driving component 210 and the bearing component 220 are respectively disposed on opposite sides of the docking assembly 230. The docking assembly 230 is movably disposed on at least one of the driving component 210 and the bearing component 220. When the driving component 210 is in the docking position, at least a portion of the docking assembly 230 is movably disposed along the second direction to drive the workpiece to be processed to move along the second direction.

[0032] In some embodiments, when the drive component 210 moves to the docking station, the docking component 230, which extends along the second direction, is movably disposed in at least one of the drive component 210 and the support component 220. It can be displaced along the second direction with the positioning action of the drive component 210. It at least partially contacts and drives the workpiece to be processed to move synchronously along the second direction, thereby realizing the automatic and precise docking of the workpiece to be processed between the drive component 210 and the support component 220. This structure uses the docking component 230 as a linkage transmission medium, so that the workpiece to be processed can move between the docking station and the processing station without the need for an additional positioning mechanism.

[0033] In the above embodiments, regarding the arrangement of the docking component 230 being movably disposed on at least one of the driving component 210 and the supporting component 220, in some embodiments, the docking component 230 is fixedly connected to the driving component 210, and the docking component 230 is movably connected to the supporting component 220. In this case, the docking component 230 acts as a rigid connecting member, moving integrally with the driving component 210, while the supporting component 220 is movable relative to the driving component 210 in a second direction. When the driving component 210 moves to the docking station, the supporting component 220 translates relative to the driving component 210 along the second direction, thereby pushing the workpiece to be processed to the processing station.

[0034] In this implementation, the drive component 210, as the high-precision positioning main body, only needs to complete the precise positioning in the first direction and does not need to bear the lateral movement load, thus reducing the inertia and energy consumption of the moving subsystem; the bearing component 220 has a lightweight structure, low lateral movement resistance, and fast response, making it suitable for high-frequency, short-stroke precision positioning scenarios; at the same time, since the docking component 230 is rigidly fixed to the drive component 210, its docking stability with the processing station is higher, and the processing conditions are guaranteed.

[0035] In other embodiments, the docking component 230 is fixedly connected to the carrying component 220, and the docking component 230 is movably connected to the driving component 210. The docking component 230 is fixedly connected to the carrying component 220, and the driving component 210 is movably connected to the docking component 230. The driving component 210 reciprocates along a second direction to transport the workpiece to be processed. In this case, the carrying component 220 and the docking component 230 form an integrated transport platform. The driving component 210 drives the entire platform to move in the second direction via a sliding structure (such as a linear guide rail or a magnetically coupled slider), realizing the lateral transport of the workpiece from the docking station to the processing station.

[0036] This implementation method features a highly integrated structure. The integration of the load-bearing component 220 and the docking assembly 230 reduces connection links and improves motion rigidity and repeatability. It is particularly suitable for heavy workpieces with a shifted center of gravity or those requiring overall load-bearing and transport, avoiding swaying or off-center loading caused by a split structure. Furthermore, the movement of the drive component 210 in the second direction can be directly achieved by a magnetic linear drive system without the need for an additional independent drive mechanism. The system has a high degree of integration and occupies a more compact space, making it suitable for high-density production line layouts where space is limited and a direct drive platform is required.

[0037] In some embodiments, the docking assembly 230 can be designed to integrate a rotating structure or a height-lifting structure, thereby realizing a variety of possibilities. Specifically, the docking assembly 230 can be equipped with an independent rotary drive mechanism, such as a micro servo motor with a planetary reducer, a magnetically coupled non-contact rotary module, or a high-precision worm gear transmission system. Its output end is directly connected to the bearing component 220, allowing the bearing component 220 to achieve continuous or indexed rotation of 0° to 360° in the horizontal plane around the vertical direction. In actual operation, after the workpiece to be processed is transported to the docking station, the control system controls the docking assembly 230 to drive the workpiece to rotate to the optimal angle according to preset process parameters, ensuring complete alignment. In addition, the docking assembly 230 can also integrate a vertical lifting module on the base that moves along the second direction, such as using a linear motor, ball screw mechanism, or pneumatic lifting cylinder, and equipped with a high-precision displacement sensor and closed-loop feedback system to achieve precise height adjustment of the bearing component 220 in the vertical direction. In other implementations, the rotation and lifting functions can work together. For example, before the workpiece is moved to the processing area, the height is first raised to a safe position, then the angle is rotated synchronously, and finally the workpiece is slowly lowered at a precise position and the posture is locked. This process can be uniformly scheduled by a PLC or motion controller and automated control can be achieved through preset process paths.

[0038] In some embodiments, the supporting component 220 adopts a modular stacked structure from bottom to top, consisting of a base, a horizontal transfer mechanism, a rotating mechanism, and a lifting mechanism. The base, as the bottom support structure of the entire supporting component 220, not only supports the upper mechanisms but also serves as the foundation platform for a stable motion pair with the second guide rail 231 and the second slider 232. The base can be integrally formed from high-strength aluminum alloy or cast iron, possessing high rigidity and deformation resistance. Its bottom is fixedly connected to the second slider 232 via bolts or locating pins, ensuring that when the driving component 210 moves along the first direction, the second slider 232 and the base move as a whole, achieving stable transmission between the docking assembly 230 and the supporting component 220.

[0039] In some embodiments, the base is the underlying support structure of the load-bearing component 220, and is directly fixedly connected to the second slider 232, while the second slider 232 is slidably engaged with the second guide rail 231 on the drive component 210. Therefore, the quantitative relationship between the base and the drive component 210 depends on the configuration of the second guide rail 231 and the second slider 232. The number of bases can be flexibly configured according to the parallel requirements of the test station. For example, in a dual-station simultaneous testing scenario, two parallel bases can be set up, each corresponding to two independent load-bearing modules, thereby realizing a parallel operation mode of "one drive, two loads" or "dual drive, two loads".

[0040] In the "one-drive, dual-load" mode: two parallel second guide rails 231 are arranged side-by-side along the second direction on a single drive component 210. A second slider 232 is slidably connected to each second guide rail 231, and an independent base (i.e., a load-bearing component 220) is fixed above each second slider 232. The two bases share a single drive component 210. When the drive component 210 moves along the first direction to the docking station, both bases simultaneously reach their positions. Subsequently, each base can move independently or synchronously along the second direction (e.g., driven by its own cylinder or lead screw), enabling parallel testing of two workpieces. In this mode, one actuator drives two load-bearing modules.

[0041] "Dual-drive, dual-load" mode: Two completely independent drive components 210 are set up. Each drive component 210 is equipped with a second guide rail 231 and a second slider 232, and a base is fixed above each second slider 232. The two drive components 210 can move independently on the first conveyor line 100, moving to their respective docking stations, and then independently completing the lateral transfer to the processing station. In this mode, the two movers drive the two load-bearing modules respectively.

[0042] With the above configuration, both the single-drive dual-load and dual-drive dual-load configurations enable parallel operation of the two bases (carrying modules), thereby doubling the number of workpieces processed in a single test cycle and significantly improving the testing efficiency per unit time, meeting the production line's requirements for high cycle time and high throughput. Among them, the "single-drive dual-load" structure is more compact and has a lower cost; while the "dual-drive dual-load" has greater independence and flexibility, and can adapt to alternating tests with different cycle times.

[0043] A horizontal transfer mechanism is installed on the base to enable the active displacement of the bearing component 220 in the second direction (lateral). Its driving method is no longer limited to the passive push of traditional cylinders, but can select an active drive scheme according to actual working conditions. Specifically, the horizontal transfer mechanism can adopt various precision drive forms such as servo motor + lead screw drive, linear motor, or synchronous belt + tension pulley, and achieve high-precision, programmable, and variable-speed movement in the second direction through closed-loop control by a controller. Compared with the shortcomings of traditional cylinders, which can only achieve two-point positioning, have uncontrollable speed, and suffer from large impacts, the active drive scheme can not only achieve a repeatability accuracy of 0.01mm, but also support micro-adjustment, multi-segment speed planning, and buffer deceleration functions, making it particularly suitable for precision shell testing with high compliance requirements for water channel sealing surfaces. At the same time, the lead screw drive structure has self-locking performance, which can effectively prevent the workpiece from shifting due to inertia or gravity in the event of power failure or emergency stop, further improving system safety.

[0044] Above the horizontal transfer mechanism, a rotating mechanism is integrated. When there is a deviation between the workpiece's position to be processed and the external mechanism, and translation alone cannot achieve perfect alignment between the nozzle and the interface, the workpiece's orientation is adjusted by rotation, allowing the external mechanism to process the workpiece at the desired position. This structure does not rely on an external turntable; it is completely embedded within the supporting component 220, significantly reducing the testing cycle time and improving the level of automation.

[0045] Above the rotating mechanism is a lifting mechanism, which functions to precisely adjust the vertical height of the supporting component 220. The lifting mechanism can employ a ball screw and servo motor drive structure, or a linear motor and grating feedback system. Its slide is directly connected to the positioning fixture 221, enabling vertical lifting and lowering control of the workpiece. This mechanism features high rigidity, high response, and low vibration characteristics. Combined with a displacement sensor, it can achieve a positioning accuracy of ±0.02mm, addressing the issue of inconsistent water channel outlet heights caused by casting tolerances, machining deformation, and assembly errors in different engine housing models. In actual operation, the system can first obtain the workpiece type and interface height through visual recognition or encoder feedback, automatically calculate the lifting amount, and perform adaptive calibration of the workpiece before it is moved to the testing station.

[0046] Specifically, the docking assembly 230 includes a second guide rail 231 and a second slider 232 that are slidably connected. The second guide rail 231 is disposed on the driving component 210, and the second slider 232 is disposed on the bearing component 220. One end of the second guide rail 231 is disposed on the first conveyor line 100. When the moving component 200 is in the docking station, the other end of the second guide rail 231 extends to the processing station so that the second slider 232 drives the workpiece to be processed to move to the docking station or the processing station.

[0047] In some embodiments, when the moving component 200 moves to the docking station, one end of the second guide rail 231 on the driving component 210 docks with the first conveyor line 100, and the other end extends to the processing station. The second slider 232 on the bearing component 220 slides in cooperation with the second guide rail 231, enabling the workpiece to be processed to move stably between the docking station and the processing station along the straight path of the second guide rail 231, avoiding the jamming and offset problems caused by inaccurate positioning or mechanical backlash in traditional conveying methods. Driven by the driving component 210, the second slider 232 slides along the second guide rail 231, directly and accurately conveying the workpiece from the first conveyor line 100 to the processing station. After processing, it slides in the opposite direction to bring the workpiece back to the docking station. This structure eliminates intermediate transmission links through the direct sliding connection between the second guide rail 231 and the second slider 232, improving motion response speed and position control accuracy.

[0048] In some embodiments, the docking assembly 230 further includes a substrate 233. The lower part of the substrate 233 is connected to the driving component 210, and a second guide rail 231 is provided on the upper part of the substrate 233. The substrate 233 extends along a second direction, forming an installation path and reliable support for the second guide rail 231. Specifically, a stop member is provided at the end of the substrate 233 away from the first conveying line 100. When the carrying component 220 moves to a preset position along the second direction, the second slider 232 can engage with the stop member to limit the movement position of the carrying component 220. At least one weight-reducing groove is provided in the middle of the substrate 233. This arrangement helps to reduce the overall weight of the substrate 233 and prevents the docking assembly 230 from being too heavy, which could lead to connection failure or breakage of the substrate 233 when the carrying component 220 moves to the end of the substrate 233 away from the first conveying line 100.

[0049] Specifically, a conveying component 300 is provided at the processing station. At least a portion of the conveying component 300 is movably arranged along the second direction. When the docking component 230 is in the docking station, the third transmission component docks with the docking component 230 to transport the workpiece to be processed on the docking component 230 to the processing station.

[0050] In some embodiments, a conveying component 300 is provided at the processing station, and at least a portion of the conveying component 300 is movable along the second direction. When the docking component 230 is at the docking station, the third transmission component and the docking component 230 are precisely docked. Through the driving action of the third transmission component, the workpiece to be processed on the docking component 230 is smoothly transferred to the conveying component 300 along the second direction, and then continuously conveyed to the processing station by the conveying component 300 along the second direction. This achieves automatic, directional, and uninterrupted transportation of the workpiece from the docking station to the processing station, ensuring high-precision positioning and stable transportation of the workpiece when it enters the testing station.

[0051] In the above embodiments, the transmission component 300 is mainly configured in the following two scenarios:

[0052] Scenario 1: Shorten the length of the docking component 230 to achieve miniaturization of the moving component 200.

[0053] When the distance between the processing station and the first conveyor line 100 is large, if the second guide rail 231 of the docking component 230 extends from the first conveyor line 100 to the processing station, the second guide rail 231 will be too long, thus increasing the overall size and weight of the mover assembly 200, which is not conducive to the lightweighting and miniaturization of the mover. In this scenario, the conveying component 300 is set as an intermediate receiving mechanism: the docking component 230 only needs to convey the workpiece to be processed to the position where it docks with the conveying component 300, and the subsequent stroke is continued by the conveying component 300 along the second direction to the processing station. In this way, the length of the second guide rail 231 of the docking component 230 can be significantly shortened, thereby reducing the inertia and space occupied by the mover assembly 200, realizing the miniaturization of the mover, while reducing the load on the drive component 210 and improving the motion response speed and flexibility.

[0054] Scenario 2: Utilize the active conveying of the conveying component 300 to improve the positioning accuracy of the workpiece when it arrives at the processing station.

[0055] When only the docking component 230 is used for conveying, the carrying component 220 slides along the second guide rail 231 using the second slider 232. Its stopping position may be limited by the mechanical clearance or inertial impact between the slider and the guide rail, making it difficult to achieve high-precision final positioning. With the conveying component 300, the conveying component 300 itself has the ability to actively move along the second direction, and an abutment 301 is provided at its end away from the docking component 230. When the workpiece is transferred from the docking component 230 to the conveying component 300, the conveying component 300 actively and precisely conveys the workpiece along the second direction until the end of the workpiece abuts against and is limited by the abutment 301. By ensuring that the orthographic projection of the abutment 301 at least partially overlaps with the orthographic projection of the carrying component 220, a consistent and precise stopping position is ensured for the workpiece at the processing station, thereby significantly improving the positioning accuracy of the workpiece when it arrives at the processing station.

[0056] In some embodiments, the conveying assembly 300 at the processing station uses a plate chain structure as the core conveying carrier, and at least part of it (such as the chain link body or the bearing platform) is movably arranged along the second direction. The plate chain structure itself has excellent rigidity and planar bearing capacity. It is composed of multiple metal chain links hinged by pins, and the top of the chain links forms a continuous, flat, and elastically deformation-free bearing surface. The plate chain is movably arranged along the second direction, which means that it is not fixedly installed, but can be driven by a drive mechanism (such as a servo motor + reducer, synchronous belt, or ball screw) to achieve active, controllable, and precise displacement along the second direction. The lateral mobility of the plate chain enables it to work in conjunction with the aforementioned docking assembly 230. After the docking assembly 230 transfers the workpiece to be processed from the docking station to the processing station, the workpiece is placed on the bearing surface of the plate chain. Anti-slip blocks are provided below the workpiece to increase friction by engaging with the surface of the plate chain. At this time, the plate chain can perform lateral fine-tuning to accurately position the workpiece.

[0057] Specifically, the length of the workpiece to be processed along the second direction is L1, and the distance between the third transmission assembly and the docking assembly 230 along the second direction is L2, wherein L2 < L1; and / or, the transmission assembly 300 further includes an abutment 301, which is disposed at the end of the transmission assembly 300 away from the docking assembly 230, and along the second direction, the orthographic projection of the abutment 301 coincides at least partially with the orthographic projection of the bearing member 220.

[0058] In some embodiments, the length of the workpiece to be processed along the second direction is L1, and the distance between the third transmission component and the docking component 230 along the second direction is L2, and L2 is less than L1. This ensures that during the process of conveying the workpiece from the third transmission component to the docking component 230, one end of the workpiece is always supported by the transmission component 300 and cannot be completely detached, thereby effectively limiting the excessive displacement of the workpiece in the second direction and avoiding positioning offset caused by suspension or insufficient support.

[0059] In other embodiments, the end of the conveying component 300 away from the docking component 230 is provided with an abutment 301. The orthographic projection of the abutment 301 along the second direction at least partially overlaps with the orthographic projection of the carrying component 220, ensuring that the workpiece to be processed is precisely limited by the abutment 301 at the end of the conveying process, so that it is aligned with the carrying component 220 in the second direction, thereby forming a stable spatial positioning relationship during the conveying and receiving process, and significantly improving the docking accuracy between the workpiece to be processed and the carrying component 220.

[0060] Specifically, an actuator 400 is provided at the processing station, and a positioning fixture 221 is provided on the bearing component 220. The positioning fixture 221 is used to clamp the workpiece to be processed. At least one clearance groove is provided on the bearing component 220 so that when the bearing component 220 is in the processing station, at least a part of the actuator 400 extends out of the clearance groove to process the workpiece to be processed.

[0061] In some embodiments, an actuator 400 is provided on the processing station, and a positioning fixture 221 is provided on the bearing component 220. The positioning fixture 221 is used to clamp the workpiece to be processed. When the bearing component 220 is transported to the processing station, at least one clearance groove on it corresponds to the movement path of the actuator 400, so that at least a part of the actuator 400 can extend out of the clearance groove in a vertical or oblique direction and directly act on the processing area of ​​the workpiece to be processed, thereby completing the processing without releasing the positioning fixture 221 from the workpiece clamping state.

[0062] Specifically, the positioning fixture 221 includes multiple main clamping members, which enclose a clamping area for clamping the workpiece to be processed. The clamping area is projected onto the bearing member 220 in the vertical direction to form a projection area, and at least one clearance groove is provided in the projection area.

[0063] In some embodiments, the positioning fixture 221 includes a plurality of main clamping members, which enclose a clamping area for clamping the workpiece to be processed. The clamping area is projected onto the support member 220 in the vertical direction to form a projection area. At least one clearance groove is provided in the projection area. The clearance groove is provided to reserve space within the projection range of the clamping area, thereby avoiding positional interference between the main clamping members and the workpiece to be processed in the vertical direction.

[0064] Specifically, the positioning fixture 221 also includes a plurality of secondary clamping members, which together form a second clamping area for clamping the workpiece to be processed. The projection of the second clamping area onto the bearing member 220 in the vertical direction forms a second projection area, and at least one clearance groove is provided in the second projection area.

[0065] In some embodiments, the positioning fixture 221 is formed by a plurality of secondary clamping members to form a second clamping area for clamping the workpiece to be processed. The projection of the second clamping area onto the bearing member 220 in the vertical direction forms a second projection area. At least one clearance groove is provided in the second projection area, so that when the secondary clamping member clamps the workpiece to be processed stably, the projection position corresponding to its clamping area is reserved with a passage, thus avoiding the obstruction of the secondary clamping member.

[0066] In other embodiments, to accommodate the rapid changeover requirements of different product models on the production line, the positioning fixture 221 includes not only multiple main clamping components but also multiple secondary clamping components. The main clamping components are used to clamp part A to be processed, and the secondary clamping components are used to clamp part B to be processed. The main and secondary clamping components are integrated together on the supporting component 220. When the production line switches from producing product A to producing product B, there is no need to disassemble or replace the entire positioning fixture 221; only the corresponding secondary clamping components need to be used for clamping, thereby significantly shortening the changeover time and improving the workpiece versatility of the production line.

[0067] Furthermore, the projection of the clamping area formed by the main clamping member along the vertical direction onto the support member 220 forms a first projection area, and the projection of the second clamping area formed by the secondary clamping member along the vertical direction onto the support member 220 forms a second projection area. Both the first projection area and / or the second projection area are provided with clearance grooves. The position and number of clearance grooves are rationally arranged so that regardless of whether the workpiece is clamped by the main clamping member (product A) or by the secondary clamping member (product B), at least a portion of the actuator 400 can extend from the corresponding clearance groove to process the lower surface of the workpiece, thereby achieving processing stability and product universality.

[0068] Specifically, the actuator 400 includes a lower jet assembly 410. When the supporting member 220 is in the processing station, the jet nozzle of the lower jet assembly 410 is positioned towards the workpiece to be processed. The lower jet assembly 410 is vertically oriented so that at least a portion of the jet nozzle extends out of the clearance groove to jet the workpiece to be processed. And / or, the actuator 400 includes an upper jet assembly 420. The upper jet assembly 420 is vertically oriented above the processing station. When the supporting member 220 is in the processing station, the jet nozzle of the upper jet assembly 420 is positioned towards the workpiece to be processed, and the lower jet assembly 410 is positioned below the processing station.

[0069] In some embodiments, when the carrier component 220 transports the workpiece to the processing station, the lower jet assembly 410 moves vertically up and down, causing its jet nozzle to extend out of the clearance groove provided below the processing station, thereby overcoming structural limitations and accurately aligning with the lower opening of the workpiece. At the same time, the upper jet assembly 420 descends synchronously above the processing station, so that its jet nozzle faces the upper inlet of the workpiece, forming a closed jet environment with opposing upper and lower parts, realizing dual-end synchronous air supply for air tightness testing. This structural design avoids interference from the jet assembly to the movement of the carrier component 220 or the switching of the processing station when the jet assembly is not in the testing state, ensuring a continuous and smooth transport process. Furthermore, through the independent lifting and lowering control of the lower jet assembly 410 and the upper jet assembly 420, it can adapt to workpieces of different heights or structures, improving the versatility and accuracy of the testing system, while ensuring that the jet pressure is concentrated on the area to be tested, improving the detection rate and testing reliability.

[0070] In some embodiments, this application adopts a "dual-station structure"—that is, two processing stations are set next to the first conveyor line, and two docking stations are correspondingly set on the first conveyor line. The two processing stations can be set on the same side of the first conveyor line or on opposite sides of the first conveyor line. The core advantage of the dual-station structure lies in the high degree of overlap in time and complete isolation in space. In traditional single-station systems, the workpiece is taken from the conveyor line → transferred to the testing area → completed the test → returned to the conveyor line. The whole process is serial, and the testing phase occupies the majority of the time, causing the conveyor line to "wait" for the test to be completed before releasing the next workpiece, which seriously drags down the cycle efficiency. In this application, since the two processing stations operate in parallel, the testing time is completely "hidden" in the conveyor cycle. That is, when the first workpiece is being processed at the first processing station, the second workpiece has already been transported to the docking station by the docking component and completed its initial positioning. It only needs to wait for the first processing station to finish processing before the right side immediately enters the processing state. The conveyor line does not need to stop, and the workpiece interval can be shortened to less than a single test cycle. In some other embodiments, multiple processing stations can also be set.

[0071] The working process of the technical solution of this application is described below:

[0072] When the workpiece is conveyed to the docking station of the first conveyor line 100, the drive component 210 moves to the docking station and stops through magnetic coupling with the first conveyor line 100. At this time, the positioning fixture 221 on the bearing component 220 has already carried the workpiece, and the second guide rail 231 of the docking assembly 230 is disposed on the drive component 210, and the second slider 232 is disposed on the bearing component 220. One end of the second guide rail 231 is located on the first conveyor line 100, and the other end extends to the processing station. After the drive component 210 completes the positioning... The second slider 232 slides along the second guide rail 231, driving the bearing component 220 and the workpiece to be processed to move from the docking station to the processing station along the second direction. During the movement of the bearing component 220 to the processing station, the conveying component 300 is movable along the second direction. The third transmission component docks with the docking component 230, smoothly transferring the workpiece from the docking component 230 to the conveying component 300, and then conveying it along the second direction until the end of the workpiece is limited by the abutment component 301. The abutment component 301 moves along the second direction... The projection of the workpiece at least partially overlaps with the orthographic projection of the supporting component 220, ensuring accurate positioning of the workpiece at the processing station. After the workpiece is positioned, the lower jet assembly 410 of the actuator 400 moves up and down, causing its jet nozzle to extend out of the clearance groove on the supporting component 220. At the same time, the upper jet assembly 420 descends from above the processing station, so that its jet nozzle faces the upper water channel inlet of the workpiece. The lower jet assembly 410 and the upper jet assembly 420 simultaneously jet gas into the internal water channel of the workpiece, achieving dual-end air supply. During the jetting process, the positioning fixture 221... Multiple main clamping components enclose a clamping area, and multiple secondary clamping components enclose a second clamping area. Both the clamping area and the second clamping area are provided with clearance grooves within their vertical projection range to ensure that the air jet nozzle does not interfere with the water channel opening of the workpiece. After the air tightness test is completed, the lower air jet assembly 410 and the upper air jet assembly 420 are reset, and the second slider 232 slides in the opposite direction along the second guide rail 231, driving the bearing component 220 and the workpiece to return to the docking station along the second direction, completing a single air tightness test cycle and realizing automatic alternating operation between the two stations.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
