If functional defects or cosmetic damage are found during product inspection, these structures require rework and disassembly. Currently, this mainly relies on manual prying with tools. Due to the compact structure and fragile material of circular injection-molded parts, manual disassembly easily leads to damage to the outer shell surface and internal structure, rendering the parts unusable and scrapped. This not only increases production costs but also wastes resources and puts pressure on the environment. Existing technology lacks an automated device capable of precise positioning, reliable clamping, and non-destructive disassembly; therefore, there is an urgent need to develop an automated disassembly device that can effectively avoid secondary damage.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Example 1 This embodiment provides a workpiece disassembly device, such as... Figures 1-11 As shown, a device for disassembling a workpiece 400 is used. The workpiece 400 includes a first housing 410 and a second housing 420 arranged vertically. The workpiece disassembly device includes a feeding module 100, a disassembly module 200, and a disassembly module 300. The feeding module 100 is used to transport the workpiece 400. The disassembly module 200 is configured to limit and fix the workpiece 400 and disassemble it to separate the first housing 410 and the second housing 420, and move the separated first housing 410 and the second housing 420 to the disassembly module 300.

[0024] The feeding module 100 automatically conveys the workpiece 400 to be disassembled, providing a continuous material supply for the subsequent disassembly process. The disassembly module 200 reliably limits and fixes the workpiece 400 conveyed to the workstation and performs the core disassembly operation, thereby separating the first shell 410 and the second shell 420 of the workpiece 400. The repackaging module 300 receives and collects the various shell components separated by the disassembly module 200, completing the final diversion and transfer of materials.

[0025] The feeding module 100, disassembly module 200, and reassembly module 300 are sequentially connected in spatial layout, forming a coherent processing path. The feeding module 100 is responsible for transporting the workpiece 400 to the workstation where the disassembly module 200 is located, and the two are closely connected at the material transfer point. The disassembly module 200, as the core processing unit, performs the disassembly action after receiving the workpiece 400. The reassembly module 300 is located at the subsequent workstation of the disassembly module 200 and is responsible for receiving the separated components.

[0026] In the specific working process, firstly, the feeding module 100 conveys the workpiece 400 to be processed to the disassembly module 200. Then, the disassembly module 200 securely limits and clamps the delivered workpiece 400, and then performs a mechanical separation action to separate the first housing 410 and the second housing 420 of the workpiece 400. Finally, the disassembly module 200 transfers the successfully separated first housing 410 and second housing 420 to the packaging module 300, where they are uniformly collected and stored. The entire process requires no complex manual intervention, achieving efficient and continuous operation.

[0027] This embodiment effectively solves the problem of workpiece damage caused by manual operation in the prior art through the integrated and automated design of the feeding module 100, disassembly module 200, and reassembly module 300. The automated conveying of the feeding module 100 avoids initial bumps that may be caused by manual handling and placement. The disassembly module 200 uses mechanized limiting, fixing, and separation actions, completely replacing the traditional method of using tools to pry, thus fundamentally eliminating the risk of dents, scratches, or damage to the internal structure on the outer shell due to improper operation. The reassembly module 300 ensures that the disassembled shell components are properly collected, creating conditions for subsequent reuse. Therefore, the entire device ensures high precision and controllability of the disassembly process through automation, significantly reducing the scrap rate of components and achieving resource conservation.

[0028] In a specific embodiment, such as Figure 1 and Figure 2 As shown, the feeding module 100 includes a conveyor belt 110 and a first sensor 120. The conveyor belt 110 carries and transports the workpiece 400. The first sensor 120 is located at the end of the conveyor belt 110 and is used to sense the position of the workpiece 400 and control the start and stop of the conveyor belt 110. The feeding module 100 and the disassembly module 200 are connected through the conveyor belt 110 to form a continuous production line. The first sensor 120 can be a photoelectric sensor.

[0029] In terms of spatial layout, the conveyor belt 110 is arranged horizontally, with its end adjacent to the limiting fixture unit 210 of the disassembly module 200, forming a material transfer area. The first sensor 120 is installed at the end edge of the conveyor belt 110, with its detection probe facing the conveying surface of the conveyor belt 110, enabling it to accurately sense whether the workpiece 400 has reached the designated position. In terms of connectivity, the first sensor 120 is connected to the control system of the conveyor belt 110 via electrical wiring. Simultaneously, the first sensor 120 maintains a signal connection with the control module of the entire device, thereby coordinating the actions of subsequent actuators such as the mechanical gripper unit 230 based on the detection status. The function of the conveyor belt 110 is to automatically carry and transport the workpiece 400 to be disassembled, realizing continuous material transfer from the manual loading position to the automatic disassembly station. The function of the first sensor 120 is to detect whether the workpiece 400 has reached the predetermined position at the end of the conveyor belt 110, and to control the operating status of the conveyor belt 110 based on the detection result. Its core function is to automate the detection and conveying control of material arrival. Together, they form an intelligent feeding system that ensures that workpiece 400 can be accurately and promptly delivered to the subsequent processing location.

[0030] During operation, the operator first places the workpiece 400 to be disassembled on the conveyor belt 110 as required. The conveyor belt 110 runs continuously, transporting the workpiece 400 to the end. When the workpiece 400 moves to the end of the conveyor belt 110 and enters the detection area of ​​the first sensor 120, the first sensor 120 immediately detects the presence of the workpiece 400 and sends a stop signal to stop the conveyor belt 110. At this time, the workpiece 400 is precisely positioned at the optimal junction of the end of the conveyor belt 110 and the disassembly module 200, creating precise positioning conditions for the subsequent gripping operation of the mechanical claw unit 230. This cooperative method achieves precise positioning and automatic stopping control of the workpiece 400 during the transport process, ensuring that the workpiece 400 can enter the disassembly stage in a stable and accurate posture. This not only improves the accuracy of loading and positioning but also avoids disassembly failures or component damage caused by inaccurate positioning, while significantly reducing the frequency of manual intervention and the difficulty of operation.

[0031] In a specific embodiment, such as Figure 2 As shown, the disassembly module 200 includes a limiting fixture unit 210, a clamping unit 220, and a mechanical claw unit 230. The limiting fixture unit 210 has a groove that matches the shape of the workpiece 400 for horizontal limiting. The clamping unit 220 is configured to lock the pin 430 at the bottom of the workpiece 400. The mechanical claw unit 230 is configured to clamp the first housing 410 of the workpiece 400 and perform the disassembly action.

[0032] The core function of the limiting fixture unit 210 is to provide a stable and precise positioning platform for the workpiece 400. Its internal groove shape matches the outline of the workpiece 400, ensuring that the workpiece 400 automatically corrects itself to a preset position when placed, establishing an accurate reference for all subsequent operations. The clamping unit 220, after the workpiece 400 is positioned, actively locks and secures its bottom pin 430, applying symmetrical clamping forces to constrain the movement of the workpiece 400 during disassembly, ensuring its stability. The mechanical gripper unit 230 performs the final execution task, grasping the first housing 410 of the fixed workpiece 400 and separating the first housing 410 from the second housing 420 by applying specific forces or movements. More specifically, the limiting fixture unit 210 constitutes the basic structure of the entire disassembly module 200, fixedly mounted on the device's working platform. The clamping unit 220 specifically consists of a first clamping cylinder 221 and a second clamping cylinder 222. These two cylinders are symmetrically installed on both sides of the limiting fixture unit 210, and the movement trajectory of their clamping heads is precisely aligned with the position of the workpiece 400 pin 430. The mechanical claw unit 230 is located above the limiting fixture unit 210, and its mechanical arm 231 is mounted on an independent bracket or crossbeam, allowing the end claw 232 to move freely to directly above the groove of the limiting fixture unit 210.

[0033] Once the workpiece 400 is placed into the groove of the limiting fixture unit 210, its precise limiting function immediately takes effect, ensuring that the pin 430 of the workpiece 400 is precisely positioned between the first clamping cylinder 221 and the second clamping cylinder 222. Immediately afterwards, the clamping unit 220 receives an action signal, and the first clamping cylinder 221 and the second clamping cylinder 222 extend synchronously, firmly clamping the pin 430 of the workpiece 400 from both sides, thus completely fixing it in place. Then, the upper mechanical gripper unit 230 begins operation; its mechanical arm 231 drives the gripper 232 downwards and clamps the first housing 410 of the workpiece 400, then performs an upward lifting or rotating separation action. During this process, since the second housing 420 is firmly locked by the clamping unit 220, the force applied by the mechanical gripper unit 230 is concentrated at the junction of the first housing 410 and the second housing 420, thereby smoothly achieving non-destructive separation. The direct effect of this collaborative working method is that it perfectly simulates a precise and controllable disassembly process, completely replacing manual prying that is prone to damage. This not only greatly protects the integrity of the workpiece 400 shell and creates conditions for secondary use, but also realizes the mechanization and automation of disassembly operations, significantly improving the consistency of work efficiency.

[0034] In a specific embodiment, such as Figures 1-6 As shown, the limiting fixture unit 210 includes a second sensor 211, which is configured to detect whether the workpiece 400 is placed in the correct position and trigger the operation of the clamping unit 220 and the mechanical gripper unit 230. The clamping unit 220 includes a first clamping cylinder 221 and a second clamping cylinder 222 symmetrically arranged. The first clamping cylinder 221 and the second clamping cylinder 222 are synchronously driven to lock the pins 430 of the workpiece 400 from both sides. The second sensor 211 can be a photoelectric sensor.

[0035] The second sensor 211 is integrated into the limiting fixture unit 210. Its core function is as a detection switch. When the workpiece 400 is placed into the groove of the limiting fixture unit 210 by the mechanical gripper unit 230 and reaches the preset accurate position, the second sensor 211 can immediately sense this state. It then generates an electrical signal, which is directly transmitted to the control system of the device. After receiving the signal, the control system will issue a start command to the clamping unit 220 and the mechanical gripper unit 230 according to the preset logic. This embodiment ensures that the clamping and disassembly actions only occur after the workpiece 400 is confirmed to be in place. This fundamentally avoids the risk of clamping failure, disassembly failure, or even component damage caused by incorrect position of the workpiece 400. At the same time, it eliminates the need for manual judgment and button operation, making the entire sequence coherent and reliable.

[0036] The clamping unit 220 consists of two symmetrically arranged clamping cylinders, a first clamping cylinder 221 and a second clamping cylinder 222. These two cylinders are located on the left and right sides of the workpiece 400's pin 430, respectively, and their movements are strictly synchronized through a control system. Upon receiving a command from the control system, they simultaneously extend their piston rods, applying equal and opposite clamping forces to the workpiece 400's pin 430 from both left and right directions. The primary effect of this symmetrical and synchronized drive is the formation of a balanced constraint, firmly locking the bottom of the workpiece 400 onto the limiting fixture unit 210, effectively preventing any movement or twisting during subsequent disassembly. Furthermore, this balanced clamping force is evenly distributed on the pin 430, avoiding deformation, wear, or even breakage of the pin 430 due to unilateral or uneven force. This achieves reliable fixation while maximizing the protection of the workpiece 400's structural integrity, laying a solid foundation for subsequent reuse.

[0037] In a specific embodiment, such as Figure 7 and Figure 8 As shown, the mechanical claw unit 230 includes a mechanical arm 231 and a claw 232. The mechanical arm 231 is configured to move in multiple degrees of freedom to position the claw 232. The claw 232 has an arc surface, and the mechanical arm 231 adopts a linkage mechanism or joint structure to achieve omnidirectional movement.

[0038] The main function of the robotic arm 231 is to provide precise motion capabilities for the entire grasping and disassembly process. Through its multi-degree-of-freedom structure, it drives the end effector 232 to move in three-dimensional space, thereby completing a series of tasks such as grasping the workpiece 400 from the conveyor belt 110, transferring it to the limiting fixture unit 210, and performing disassembly on the first housing 410 of the workpiece 400. The claw 232 directly contacts the workpiece 400; its internally designed curved surface conforms well to the circular outer shell of the workpiece 400, reliably gripping the first housing 410 through clamping force, and applying a specific force under the drive of the robotic arm 231 to separate the upper and lower housings.

[0039] The robotic arm 231 is typically mounted as a single unit on a worktable base or independent support near the limiting fixture unit 210. Its mounting position must ensure that the range of motion of the gripper 232 fully covers the end of the conveyor belt 110, the groove of the limiting fixture unit 210, and the area above the disassembly module 300. The gripper 232 is directly fixed to the actuator at the end of the robotic arm 231 via a standard mechanical interface. This connection ensures that all movements of the robotic arm 231 are precisely transmitted to the gripper 232. Furthermore, the entire robotic gripper unit 230 is spatially closely associated with the limiting fixture unit 210 and the clamping unit 220. After the workpiece 400 is limited and clamped, the robotic arm 231 can accurately move the gripper 232 directly above the workpiece 400, preparing it for disassembly.

[0040] In the specific working process, firstly, when workpiece 400 is detected at the end of conveyor belt 110, robotic arm 231 drives claw 232 to move above workpiece 400, and then claw 232 closes to grasp workpiece 400. Next, robotic arm 231 lifts and rotates, smoothly transporting workpiece 400 and placing it into the groove of limiting fixture unit 210. After workpiece 400 is reliably locked by clamping unit 220, robotic arm 231 is precisely positioned again, causing claw 232 to descend and clamp the first housing 410 of workpiece 400. Finally, robotic arm 231 executes a preset separation motion trajectory, which may be a vertical lift, a slight rotation, or a peeling at a specific angle. At this time, claw 232 firmly grips the first housing 410, thus smoothly separating it from the second housing 420. The core effect of this collaborative work is that it achieves full automation and high precision in the disassembly process. It perfectly replaces manual operation, which not only significantly improves efficiency, but more importantly, through the stable force and movement path controlled by mechanical control, it completely avoids the damage to the outer shell and internal structure caused by traditional prying methods, and greatly ensures the integrity of the disassembled parts for secondary use.

[0041] Additionally, the linkage mechanism can be formed by connecting multiple rigid links sequentially via revolute joints or hinges, creating a kinematic chain similar to a scissor brace or parallelogram. The characteristic of this structure is that when one link is driven to rotate by a motor, it drives other links and the end effector 232 to produce the desired movement trajectory through fixed geometric relationships, such as achieving a precise linear lift or circular swing. The joint structure can be understood as simulating the construction of a human arm, containing multiple motor-driven rotary joints connected in series, like the shoulder, elbow, and wrist. Each joint can rotate independently in one or more directions, allowing the entire robotic arm 231 to perform flexible, multi-angle movements in three-dimensional space to deliver the end effector 232 to different positions and postures. Both the linkage mechanism and the joint structure internally contain a motor or servo drive as the power source, and transmission components such as gears or belts to transmit power to the various moving parts. These structures are ultimately mounted on the device's work platform via a stable base, ensuring a reliable connection between the output flange at the end effector and the end effector 232.

[0042] In a specific embodiment, the arc surface of the claw 232 is adapted to the inner side of the jaws to be padded with a rubber pad or a velvet cloth, and the claw 232 is opened and closed to grasp by a gear transmission driven by a motor. The arc shape of the claw 232 is adapted to the outer surface of the workpiece 400.

[0043] The portion of the jaw 232 that contacts the workpiece 400 is designed as a curved, adaptive jaw. This means that the curvature of its concave surface is specially calculated to closely match the circular outer surface of the workpiece 400, thus creating a large contact area. More importantly, a layer of rubber or velvet is firmly attached to the inner side of this curved jaw. This flexible medium acts as a buffer interface, directly intervening between the jaw 232 and the rigid outer shell of the workpiece 400. In terms of drive mechanism, the opening and closing motion of the jaw 232 is powered by a motor. This motor converts the rotational motion into the parallel opening and closing of the jaws through a set of precision gear transmission mechanisms. This drive method allows for precise control of the clamping force and stroke.

[0044] This embodiment achieves safe, stable, and non-destructive gripping of workpiece 400. The curved surface adaptation design ensures a uniform distribution of gripping force, avoiding stress concentration. The inner rubber pad or felt plays a dual role: firstly, it significantly increases the friction between the claw 232 and the workpiece 400's outer shell, effectively preventing slippage during lifting or disassembly; secondly, its soft texture absorbs localized pressure, completely preventing the hard metal or plastic claws from leaving indentations, scratches, or dents on the smooth outer shell of workpiece 400. Simultaneously, the drive system, composed of a motor and gear transmission, provides a smooth and controllable clamping force, overcoming the impacts that may arise from pneumatic or hydraulic drives, further ensuring the gentleness and precision of the gripping process.

[0045] In a specific embodiment, such as Figure 1 and Figure 4 As shown, the disassembly module 300 includes a first collection area 310 and a second collection area 320, which are respectively used to store the disassembled first housing 410 and second housing 420.

[0046] The disassembly module 300 is internally divided into two independent storage areas: a first collection area 310 and a second collection area 320. The first collection area 310 is designated for receiving and temporarily storing the first housing 410 separated from the workpiece 400, while the second collection area 320 is designated for receiving and storing the second housing 420. This design means that after the robotic gripper unit 230 completes the disassembly operation, it will move the two different housings to their respective collection areas according to the instructions of the control system, thereby achieving an orderly flow from the disassembly station to the sorting and storage point.

[0047] During the disassembly process, after the first housing 410 and the second housing 420 are separated, without such a sorting and collection mechanism, they may become mixed together, requiring additional manual sorting. This is not only inefficient but may also cause secondary scratches or confusion of the parts during the process. By setting up the first collection area 310 and the second collection area 320, the device automatically distinguishes and places different parts immediately after the disassembly step. This orderly collection method allows subsequent maintenance, testing, or reassembly processes to directly retrieve the correct parts from the corresponding collection area, greatly improving the efficiency and accuracy of subsequent operations. Furthermore, this automatic sorting method avoids the risk of damage caused by collisions between different parts, ensuring the integrity of the disassembled housings, especially the second housing 420 planned for reuse. From the overall process perspective, this consolidates and enhances the core value of this automated disassembly device in reducing losses and saving costs.

[0048] In a specific embodiment, the workpiece disassembly device further includes a control module, which is configured to control the feeding module 100, the disassembly module 200, and the packaging module 300 based on the sensing signals of the first sensor 120 and the second sensor 211.

[0049] This embodiment equips the entire workpiece disassembly device with a unified control module. This module acts as the central nervous system of the device, continuously receiving detection signals from the first sensor 120 and the second sensor 211. Specifically, when the first sensor 120 reports that the workpiece 400 has arrived at the end of the conveyor belt 110, and the second sensor 211 confirms that the workpiece 400 has been securely placed on the limiting fixture unit 210, the control module will issue precise instructions to each functional module according to these key status information and preset program logic. These instructions coordinate the start and stop of the conveyor belt 110 in the feeding module 100, the locking and unlocking of the clamping unit 220 in the disassembly module 200, the gripping and separating actions of the mechanical claw unit 230, and the component transfer process involved in the packaging module 300, thereby integrating the three originally independently operating modules into a coherent automated system.

[0050] The control module in this embodiment replaces the traditional operation mode that relies on operator observation, judgment, and manual execution of each step, enabling seamless and automated operation of all stages from workpiece 400 loading, positioning, clamping, disassembly to final packaging. This centralized control based on real-time signals greatly improves the consistency and stability of the operation rhythm, effectively eliminating efficiency bottlenecks caused by intervals or inconsistent rhythms of manual operation, thereby achieving a qualitative leap in overall operation efficiency. Furthermore, this precise timing control ensures that every critical action, such as the locking of the clamping unit 220, occurs only after the workpiece 400 is accurately positioned, and the disassembly action of the mechanical gripper unit 230 is only performed under the premise that the workpiece 400 is reliably fixed. This fundamentally eliminates the possibility of equipment jamming or accidental damage to the workpiece 400 caused by disordered action sequence, ensuring the safety and reliability of the processing process, and ultimately achieving high-quality, high-efficiency, non-destructive disassembly operations.

[0051] In a specific embodiment, the groove shape of the limiting fixture unit 210 matches the bottom structure of the workpiece 400 so that the pin 430 of the workpiece 400 can be aligned with the clamping unit 220.

[0052] The contour of the groove in the limiting fixture unit 210 complements the structure of the bottom of the workpiece 400. This means that the groove is not a simple circular or square recess, but is precisely designed to mimic the curves, edges, or specific protrusions that may exist on the bottom of the workpiece 400. When the workpiece 400 is placed into the groove, its unique bottom structure naturally engages with the corresponding part of the groove. This engagement naturally guides the workpiece 400 to rotate or move to a unique, preset, correct position. The direct purpose and result of this process is to ensure that the pin 430 at the bottom of the workpiece 400 can automatically and accurately move to the exact center position of the two clamping components, the first clamping cylinder 221 and the second clamping cylinder 222, without the need for manual fine-tuning, thus creating a prerequisite for reliable locking.

[0053] When placing the workpiece 400, the operator or the robotic gripper unit 230 does not need to perform complex alignment operations. They only need to roughly place the workpiece 400 into the groove, and its unique shape will automatically correct itself, guiding the pin 430 to the predetermined position. This reduces the technical requirements for operators and significantly shortens the positioning time required after each loading, thereby improving the overall cycle time of the disassembly process. Furthermore, this precise pre-positioning fundamentally eliminates the risk of clamping failure due to incorrect placement or positional deviation of the workpiece 400. It ensures that the first clamping cylinder 221 and the second clamping cylinder 222 can apply force evenly and stably to the pin 430 from both sides, avoiding potential breakage of the pin 430 and damage to the cylinders due to unilateral force or gap clamping.

[0054] In a specific embodiment, such as Figures 9-11 As shown, the workpiece 400 is an air conditioner companion, which has a circular outer shell and a pin structure. The disassembly module 200 is configured to disassemble the first shell and the second shell of the air conditioner companion.

[0055] This embodiment specifies that the device is applied to the smart home product of an air conditioner companion, and points out two key structural characteristics of the workpiece: first, its outer shell is generally circular; second, its bottom is designed with a pin structure for installation or fixation, and the aforementioned pin 430.

[0056] Because air conditioner adapters generally adopt a circular outer shell and a bottom pin, the design of this device, such as the matching groove of the limiting tooling unit 210, the arc-shaped adapting jaws of the mechanical claw unit 230, and the synchronous locking of the pin 430 by the clamping unit 220, can all be optimized and adjusted based on these precise physical characteristics. More specifically, the arc-shaped claw 232 can perfectly fit the circular outer shell, avoiding pinching damage; the limiting groove can ensure that the pin 430 is accurately aligned with the clamping unit 220. This deep adaptation ensures that the entire automated disassembly process is highly reliable and efficient for air conditioner adapter products, and can stably achieve the non-destructive disassembly goal pursued in the background technology, thereby increasing the secondary utilization rate of the lower shell by more than 80%, effectively solving the pain points in the rework process of this specific product, and avoiding scrap losses caused by manual disassembly.

[0057] The operation of the workpiece disassembly device provided in this embodiment begins with the loading module 100. The operator places the air conditioner accessory with a circular outer shell and a pin 430 onto the conveyor belt 110. The conveyor belt 110 starts and transports the workpiece 400 toward the disassembly module 200. When the workpiece 400 moves to the end of the conveyor belt 110, the first sensor 120 detects its presence and immediately sends a signal. Upon receiving this signal, the control module instructs the conveyor belt 110 to stop running. At this time, the workpiece 400 accurately stops at the gripping station. Immediately afterwards, the mechanical gripper unit 230 in the disassembly module 200 starts to move. The robotic arm 231 moves its end gripper 232 above the workpiece 400. The gripper 232 uses its curved surface to adapt to the jaws and uses the inner rubber pad or velvet to firmly and without damage grip the workpiece 400. Then, the robotic arm 231 transfers the workpiece 400 and places it into the groove of the limiting fixture unit 210. Because the shape of the groove precisely matches the bottom structure of the workpiece 400, the workpiece 400 is automatically guided to the only correct position, so that its pin 430 is exactly aligned with the symmetrically arranged first clamping cylinder 221 and second clamping cylinder 222.

[0058] Once the workpiece 400 is securely placed on the limiting fixture unit 210, the second sensor 211 is triggered, sending a detection signal to the control module. The control module then instructs the clamping unit 220 to operate, with the first clamping cylinder 221 and the second clamping cylinder 222 driving synchronously to firmly lock the pins 430 of the workpiece 400 from both sides, thus completely fixing the second housing 420 portion of the workpiece 400. Next, the mechanical gripper unit 230 performs another precise operation, with the gripper 232 descending and clamping the first housing 410 of the workpiece 400. Subsequently, the robotic arm 231 executes a specific separation movement according to a preset program, either lifting or twisting. Since the second housing 420 is fixed, the applied force allows the first housing 410 to separate smoothly from the second housing 420. After disassembly, the control module controls the clamping unit 220 to release, and the robotic arm 231 transfers the separated first housing 410 and second housing 420 to the corresponding first collection area 310 and second collection area 320 in the packaging module 300 for storage. Operators periodically remove the sorted shell components from the collection area. This completes one work cycle. The control module resets the system, and conveyor belt 110 restarts, ready to receive the next workpiece 400, thus achieving continuous, automated, and efficient disassembly operations.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
