Description

Technical Field

[0001] This invention relates to the field of automated warehousing and electronic manufacturing material handling technology. Specifically, it relates to a device and control method for the automatic separation, intermittent conveying, precise transfer, and stacking of mixed-specification storage units in the SMT (Surface Mount Technology) production process. Background Technology

[0002] In the SMT industry, material storage units (trays) are typically divided into two sizes: large and small, which are stored together in storage units or warehouses. On automated production lines, these storage units need to be sequentially removed from the conveyor belt and ultimately stacked for storage. However, existing storage unit handling equipment generally suffers from the following problems: First, existing equipment generally lacks an integrated device capable of automatically identifying and separating mixed incoming materials (large-sized storage units and small-sized storage units). Existing storage unit processing equipment can typically only handle single-sized storage units. When storage units of different sizes are transported together, manual sorting or complex multi-stage conveyor lines are required, resulting in low efficiency and high labor costs.

[0003] Secondly, existing equipment struggles to achieve orderly spacing between storage units of different sizes. Because large and small storage units have different diameters, they are prone to jamming, overlapping, or inability to separate when they travel end-to-end or side-by-side on the conveyor belt, severely impacting the stability of subsequent stacking processes. While some existing equipment can detect the position of storage units using sensors, it lacks an effective mechanism to handle the special case of "large storage units immediately following small storage units," easily leading to jamming at obstructions or small storage units passing through together with large ones, resulting in spacing control failure.

[0004] Furthermore, traditional stacking and collection devices have simple structures, often employing manual stacking or simple lifting stacking, lacking reliable one-way check mechanisms. This results in uneven stacking, easy scattering, and difficulty in adapting to the stacking requirements of storage units of different sizes. Some automated stacking devices use multi-cylinder linkage structures, which are costly and inconvenient to maintain.

[0005] To address the aforementioned issues, the applicant has proposed an integrated device and method capable of automatically separating hybrid storage units, enabling interval delivery, precise transfer, and reliable stacking. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing SMT memory cell processing equipment, such as difficulty in automatically separating mixed-specification memory cells, inability to achieve orderly interval delivery, and poor stacking reliability. This invention provides an SMT memory cell automatic processing equipment and its control method that is compact, highly adaptable, stable in operation, and capable of achieving full-process automation.

[0007] To achieve the above objectives, the present invention proposes an automatic processing device for SMT memory cells, comprising: A conveying mechanism for transporting mixed storage units of various specifications along the conveying direction; A guiding mechanism, disposed at the input end of the conveying mechanism, is used to guide one type of storage unit to a predetermined conveying path by utilizing the height difference between the various types of storage units. An interval separation mechanism, disposed downstream of the guide mechanism, includes a blocking component and a first detection component. The blocking component, in response to the detection result of the first detection component on the storage cell specifications, selectively allows a single storage cell to pass or blocks subsequent storage cells from passing, thereby achieving an interval between storage cells. A transfer mechanism, disposed downstream of the interval separation mechanism, is used to lift the intervalized individual storage units from the conveying mechanism; and A collection mechanism, located above or to the side of the transfer mechanism, is used to receive and stack the storage units delivered by the transfer mechanism.

[0008] Furthermore, the guiding mechanism includes: a first guiding section, which is formed by the side flanges on both sides of the conveying mechanism, for conveying and guiding the first specification storage unit with a smaller height; and a second guiding section, which is disposed above the first guiding section and includes at least two oppositely arranged guiding members, the two guiding members forming a flared section in the shape of a trumpet at the input end, for guiding the second specification storage unit with a larger height to move along the conveying direction and gradually converge into a single column.

[0009] Furthermore, the guide is an adjustable rod, and the guide mechanism also includes an adjustment assembly connected to the frame, the adjustment assembly being used to adjust the installation height of the guide and / or the relative distance between the two guides at the input end.

[0010] Furthermore, the blocking assembly includes a first blocking member and a second blocking member symmetrically arranged on both sides of the conveying mechanism, and a first driving member that drives the first blocking member and the second blocking member to rotate in opposite directions or in opposite directions; when the first blocking member and the second blocking member rotate in opposite directions, they form a variable-diameter accommodating space between them for selectively accommodating or releasing the storage unit.

[0011] Furthermore, the interval separation mechanism also includes an auxiliary blocking member, which is disposed upstream of the blocking assembly and is used to intercept and block subsequent storage units when the blocking assembly is activated.

[0012] Furthermore, the transfer mechanism includes: a lifting drive component; a connecting plate connected to the output end of the lifting drive component; and at least one pair of grippers symmetrically arranged on the connecting plate, wherein the top of the grippers is provided with a first supporting portion and a second limiting portion, the first supporting portion being used to support the body of the storage unit, and the second limiting portion being used to abut against the edge structure of the storage unit.

[0013] Furthermore, the collection mechanism includes: a frame body forming a longitudinal accommodating space for stacking storage units; a plurality of limiting rods spaced circumferentially on the inner wall of the frame body for limiting the horizontal displacement of the stacked storage units; and at least one set of one-way check components disposed on the inner wall of the frame body, the one-way check components allowing the storage units to pass unidirectionally from bottom to top and resetting after the storage units have passed to support the storage units from below.

[0014] Furthermore, the one-way check component includes a movable member and an elastic member. The movable member retracts against the elastic force of the elastic member when the storage unit is inserted, and is driven to return to the extended state by the elastic member after the storage unit has passed through.

[0015] Furthermore, the first detection component includes a sensor group that is staggered in height to correspond to different storage unit specifications, used to distinguish storage units of different heights and generate corresponding trigger signals.

[0016] Furthermore, the guiding mechanism, the interval separation mechanism, the transfer mechanism, and the collecting mechanism are configured to be adaptably adjusted in size and structure according to the specifications of different storage units. Specifically, the guiding mechanism can adjust the installation height and relative distance of the guide members; the interval separation mechanism can adjust the accommodating space diameter of the blocking component; the transfer mechanism can change or adjust the shape of the gripper; and the collecting mechanism can adjust the position of the limiting rod and the one-way check component.

[0017] Furthermore, the present invention also provides an automatic processing method for SMT memory cells, applied to the automatic processing device for SMT memory cells described in any of the above technical solutions, comprising the following steps: The conveying step involves transporting mixed storage units of various specifications via a conveying mechanism; The guiding step utilizes the height difference between storage units to guide one type of storage unit to a predetermined transport path via a guiding mechanism; The interval separation step detects the specifications of the incoming storage units and, based on the detection results, selectively allows a single storage unit to pass or blocks subsequent storage units from passing, thus creating a predetermined interval between the storage units. The transfer step involves lifting the spaced-out individual storage units from the conveying mechanism; and In the collection step, the lifted storage units are stacked into the collection mechanism.

[0018] Beneficial effects Compared with the prior art, the present invention has at least the following beneficial effects: Firstly, this invention achieves automatic flow separation by setting up a guiding mechanism and utilizing the height difference between storage units of different sizes: small storage units are arranged into a single column through the upper flared guide section, while large storage units are normally conveyed through the lower baffle guide section. Thus, the initial separation of mixed incoming materials can be completed without manual intervention, significantly improving processing efficiency.

[0019] Secondly, by setting up an interval separation mechanism, especially a blocking assembly composed of a first blocking member and a second blocking member that can rotate in opposite directions, the present invention can dynamically adjust the size of the accommodating space according to the specifications of the storage unit detected by the sensor, thereby achieving precise interval control that "only one storage unit is allowed to pass at a time"; at the same time, the auxiliary blocking member can intercept subsequent small-sized storage units when the blocking assembly is in action, effectively preventing material jamming or following phenomena, and ensuring the stability of the conveying.

[0020] Thirdly, the transfer mechanism of the present invention uses a gripper with a stepped structure, with the first supporting part supporting the storage unit and the second limiting part abutting the edge, which realizes stable gripping and precise lifting of the storage unit, providing positional accuracy for subsequent stacking.

[0021] Fourth, the collection mechanism of the present invention adopts a one-way check valve component (live buckle structure). When the storage unit is pushed in from the bottom, the movable part is automatically pushed open. After passing through, the movable part is reset under the action of the elastic part, and the storage unit is reliably supported from below, realizing automatic stacking without additional power. Multiple limit rods ensure the neatness of stacking, and the structure can be adjusted to accommodate storage units of different diameters.

[0022] Fifth, this invention integrates five major modules—conveying, guiding, interval separation, transfer, and collection—into one compact structure, is easy to adjust, and can adapt to the automated processing of various storage units (especially suitable for large and small storage units in the SMT industry), thus having good market application prospects.

[0023] Sixth, the present invention also provides a corresponding control method, which forms a complete "device + method" dual protection with the equipment, enabling fully automated storage unit processing flow and further improving the intelligence level of the production line.

[0024] Seventh, this invention achieves high versatility and flexible production capabilities by configuring the guiding mechanism, spacing separation mechanism, transfer mechanism, and collection mechanism to be adaptable in size and structure according to the specifications of different storage units. Specifically, by simply adjusting the installation height and spacing of the guide components, adjusting the accommodating space diameter of the blocking components, changing or adjusting the shape of the grippers, and adjusting the position of the limit rod and the one-way check component, the same device can be adapted to various storage units of different specifications (such as SMT trays, chip carrier trays, blister packs, component boxes, etc.) without redesigning or replacing the entire machine, greatly expanding the application range of the equipment and reducing the user's equipment procurement and maintenance costs.

[0033] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0034] Example: To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0035] In the following description, those skilled in the art will recognize that throughout this discussion, components may be described as individual functional units (which may include subunits). However, those skilled in the art will recognize that various components or portions thereof may be divided into individual components or integrated together (including within a single system or component). Furthermore, the connections between components or systems are not intended to be limited to direct connections; rather, data between these components may be modified, reformatted, or otherwise altered by intermediate components. Additionally, additional or fewer connections may be used. It should also be noted that the terms “link,” “connection,” or “input” should be understood to include direct connections, indirect connections via one or more intermediate devices, and wireless connections.

[0036] Example 1 (Basic Example) Existing SMT material storage unit processing solutions generally suffer from the following technical limitations: On the one hand, in existing equipment, storage units of different sizes are usually mixed on the conveyor belt. Due to the lack of an automatic guiding structure based on height differences, small storage units are easily placed side by side or staggered with large storage units, making it impossible for subsequent processes to distinguish them. This can only rely on manual sorting, which seriously affects the efficiency of automation.

[0037] On the other hand, even if some devices can identify the storage cell specifications, they lack an effective spacing separation mechanism. In particular, for the special case of "large storage cells followed by small storage cells", it is easy for obstructions to jam or small storage cells to pass through together with large storage cells, which will cause spacing control failure and thus affect the reliability of stacking and collection.

[0038] In addition, traditional stacking collection devices often use simple lifting and gravity stacking without a one-way locking structure, resulting in limited stacking height and easy tilting and collapse; or they use complex multi-cylinder linkage structures, which are costly and inconvenient to maintain.

[0039] To address the aforementioned issues, the applicant recognized the need to construct an automated SMT storage cell processing device and method integrating guided flow division, dynamic spacing, precise transfer, and unidirectional stacking. Specifically, the device should utilize the height differences between storage cells of varying sizes to achieve automatic flow division via a guiding mechanism; it should employ rotatable blocking components to create a variable-diameter accommodating space for individual release; it should include auxiliary blocking components to intercept subsequent smaller storage cells; it should utilize stepped grippers for stable transfer; and it should employ a unidirectional snap-lock structure in the collection mechanism for reliable stacking.

[0040] like Figures 1 to 7 As shown, this embodiment proposes an automatic processing device for SMT storage units, including a conveying mechanism 100, a guiding mechanism 200, a spacing separation mechanism 300, a transfer mechanism 400, and a collection mechanism 500.

[0041] Conveying mechanism 100 The conveying mechanism 100 is a belt conveyor, whose conveyor belt runs continuously in the horizontal direction, and is used to transport storage units 600 of two sizes: large-size storage units and small-size storage units. Side guards are provided on both sides of the conveying mechanism 100, forming part of the first guide section 210.

[0042] Guiding mechanism 200 A guiding mechanism 200 is disposed at the input end of the conveying mechanism 100. The guiding mechanism 200 includes a first guiding section 210 and a second guiding section 220. The first guiding section 210 is formed by the side flanges on both sides of the conveying mechanism 100 and is used to guide and convey smaller first-size storage units (large-size storage units, approximately 30mm in total height). The second guiding section 220 is disposed above the first guiding section 210 and includes two opposing guide members 221. The two guide members 221 form a flared, trumpet-shaped opening at the input end, used to guide larger second-size storage units (small-size storage units, approximately 40mm in total height) to move along the conveying direction and gradually converge into a single column. The guide members 221 are adjustable rods. The guiding mechanism 200 also includes an adjustment assembly 222 connected to the frame. The adjustment assembly 222 is used to adjust the installation height of the guide members 221 and the relative distance between the two guide members 221 at the input end to accommodate different sizes of small-size storage units.

[0043] Interval separation mechanism 300 The separation mechanism 300 is located downstream of the guide mechanism 200. The separation mechanism 300 includes a blocking assembly 310, a first detection assembly 330, and an auxiliary blocking member 320. The blocking assembly 310 includes a first blocking member 311 and a second blocking member 312 symmetrically arranged on both sides of the conveying mechanism 100, and a first driving member 313 (e.g., a rotary cylinder) that drives the first blocking member 311 and the second blocking member 312 to rotate in opposite directions. The first blocking member 311 and the second blocking member 312 are triangular in shape with concave arc-shaped inner walls. When blocking is required, they rotate in opposite directions, reducing the diameter of the accommodating space between them to less than the diameter of the storage unit; when releasing is required, they rotate in opposite directions, increasing the diameter of the accommodating space and allowing the storage unit to pass through. The first detection assembly 330 includes two sets of sensors arranged at different heights, located at the outlet end of the guide mechanism 200, used to distinguish between large and small storage units and generate trigger signals. The auxiliary blocking component 320 is located upstream of the blocking assembly 310, specifically two symmetrically arranged cylinders. When the blocking assembly 310 is activated (e.g., when processing a large-size storage unit), the rod of the auxiliary blocking component 320 extends to intercept subsequent small-size storage units, preventing them from entering the blocking assembly 310 and causing jamming or following.

[0044] Transfer agency 400 The transfer mechanism 400 is located downstream of the separation mechanism 300. The transfer mechanism 400 includes a lifting drive 410 (e.g., a cylinder), a connecting plate 420, and at least one pair of grippers 430. The lifting drive 410 is located below the conveying mechanism 100, and its output end is connected to the connecting plate 420. A pair of grippers 430 are symmetrically arranged on the connecting plate 420. The top of each gripper 430 has a first supporting portion 431 and a second limiting portion 432. The first supporting portion 431 is a lower stepped plane used to support the bottom of the storage unit 600 body; the second limiting portion 432 is a higher stepped inner wall used to abut against the upward-curved edge or edge of the storage unit 600, thereby stabilizing the storage unit when lifted.

[0045] Collection agency 500 The collection mechanism 500 is positioned above the transfer mechanism 400. The collection mechanism 500 includes a frame body 510, multiple limiting rods 520, and at least one set of one-way check components 530. The frame body 510 is a hollow annular structure, forming a longitudinal accommodating space. Multiple limiting rods 520 are circumferentially spaced and vertically arranged on the inner wall of the frame body 510 to limit the horizontal displacement of the stacked storage units. The one-way check components 530 are symmetrically arranged on the inner wall of the frame body 510, each set including a movable member 531 and an elastic member (e.g., a spring-loaded ball or a spring-loaded locking block). When a storage unit 600 is pushed in from below, the movable member 531 retracts against the elastic force of the elastic member; after the storage unit 600 passes, the movable member 531 returns to its extended state under the action of the elastic member, supporting the edge or flange of the storage unit 600 from below, thereby achieving one-way stacking.

[0046] Working principle and control method This invention also provides an automatic processing method for SMT storage units, and its workflow will be described in detail below with reference to the above-mentioned equipment.

[0047] The first step is the conveying process: the mixed storage units (large-size storage units and small-size storage units) are fed in by the conveying mechanism 100.

[0048] Next, the guiding process begins: the storage units pass through the guiding mechanism 200. Larger storage units, which are shorter (approximately 30mm), are directly constrained by the first guide section 210 (edge) and continue moving forward; smaller storage units, which are taller (approximately 40mm), are guided by the flared guide 221 of the second guide section 220, gradually converging into a single column and being transported along a predetermined path. By adjusting the component 222, the height of the guide 221 and the size of the flared opening can be changed to accommodate smaller storage units of different sizes.

[0049] Then, the interval separation step is performed: the guided storage units enter the interval separation mechanism 300. The first detection component 330 detects the specifications (height) of the incoming materials. When a large-sized storage unit is detected, the first blocking member 311 and the second blocking member 312 of the blocking component 310 remain open (the accommodating space diameter is larger than the diameter of the large-sized storage unit), allowing the large-sized storage unit to pass through. After the large-sized storage unit passes through, if the first detection component 330 detects a small-sized storage unit immediately following behind, it controls the auxiliary blocking member 320 to extend and intercept the small-sized storage unit, preventing it from following the large-sized storage unit into the subsequent station. When a small-sized storage unit is detected, the blocking component 310 first drives the first blocking member 311 and the second blocking member 312 to rotate in opposite directions, reducing the accommodating space diameter to less than the diameter of the small-sized storage unit, thereby blocking the small-sized storage unit; then, after confirming that the small-sized storage unit has stopped, the first detection component 330 controls the blocking component 310 to rotate in the opposite direction, expanding the accommodating space diameter to greater than the diameter of the small-sized storage unit, allowing the small-sized storage unit to pass through. This process is repeated to achieve the predetermined interval between storage units (i.e., only one storage unit is allowed to pass through at a time).

[0050] Next, the transfer process begins: the individual storage units (whether large or small) continue to the transfer mechanism 400 after the interval. Once the sensor detects the storage unit's arrival, the lifting drive 410 raises the connecting plate 420 and the gripper 430. The first support portion 431 of the gripper 430 supports the bottom of the storage unit body, and the second limiting portion 432 abuts against the edge of the storage unit, lifting the storage unit from the conveying mechanism 100 and continuing to feed it upwards into the collection mechanism 500.

[0051] Finally, the collection step is performed: the storage unit enters the frame 510 of the collection mechanism 500, pushing upwards to open the movable part 531 of the one-way check component 530. After the storage unit passes through, the movable part 531 is driven to reset by the elastic component, locking the flange of the storage unit from below, thus suspending and fixing the storage unit in place. The transfer mechanism 400 descends, preparing for the next transfer. Subsequent storage units repeat the above process, stacking sequentially below existing storage units (due to the one-way nature of the one-way check component 530, subsequent storage units will be pushed to a higher position, stacking upwards in sequence). When the number of stacked units reaches a preset value, the entire stack of storage units can be removed.

[0052] Throughout the process, the timing of each mechanism's actions is coordinated and controlled by a programmable logic controller (PLC) based on sensor signals, achieving fully automatic operation.

[0053] Example 2 (Variant Example: Multi-specification Expansion and Series Structure) This embodiment is basically the same as embodiment 1, except that the device in this embodiment can handle three or more types of storage units, and the collection mechanism 500 adopts a series multi-layer stacked structure.

[0054] Specifically, in the SMT industry, in addition to the common large-size memory cells (approximately 330mm in diameter) and small-size memory cells (approximately 178mm in diameter), there are also medium-size memory cells (approximately 250mm in diameter). To accommodate the mixed processing of these three sizes, this embodiment makes the following improvements to the guide mechanism 200: The guiding mechanism 200 includes three layers of guiding sections: the first guiding section 210 (the lowest layer) is formed by the side guards on both sides of the conveying mechanism 100, and is used to guide the storage units with the smallest height (e.g., small-sized storage units); the second guiding section 220 is located above the first guiding section 210 and includes a pair of first flared guide members, and is used to guide the storage units with medium height (e.g., medium trays); the third guiding section is located above the second guiding section 220 and includes a pair of second flared guide members, and is used to guide the storage units with the largest height (e.g., large-sized storage units). The three guiding sections are stepped flared at the input end, each guiding the storage units of the corresponding height into the corresponding conveying channel, and finally converging on the same conveyor belt but in a single-row queue.

[0055] The spacing separation mechanism 300 is equipped with three sets of blocking components with different diameter ranges, corresponding to the spacing control of small-sized storage cells, medium-sized cells, and large-sized storage cells, respectively. Each set of blocking components includes a blocking element that can rotate in opposite directions and a corresponding auxiliary blocking element. The first detection component 330 includes three sets of height-displacement sensors, used to detect the three different storage cell heights. The control logic adopts a priority order: when multiple sizes are detected simultaneously, the storage cell with the largest diameter is processed first, followed by the cells below.

[0056] The collection mechanism 500 adopts a series structure: a first collection station (for small-sized storage units), a second collection station (for medium-sized storage units), and a third collection station (for large-sized storage units) are sequentially arranged along the conveying direction. The structure of each collection station is the same as that of the collection mechanism 500 in Embodiment 1, including a frame body 510, a limiting rod 520, and a one-way check valve assembly 530. After being separated, the storage units are lifted by the corresponding transfer mechanism 400 according to their specifications and sent to the corresponding collection station for stacking. Guide baffles are provided between each collection station to ensure that storage units do not mistakenly enter the wrong collection station.

[0057] The advantages of this embodiment are: it can simultaneously handle mixed storage units of various specifications, achieving broader material adaptability, and is especially suitable for scenarios with a wide variety of materials in SMT production lines. The serial collection station layout allows storage units of different specifications to be stacked separately, facilitating subsequent warehouse management.

[0058] Example 3 (Variant Example: Blocking Component Driving Method and Collection Mechanism Adjustment Structure) This embodiment is basically the same as Embodiment 1, except that the driving method of the blocking component 310 and the adjustment structure of the collecting mechanism 500 are different.

[0059] Regarding the driving method of the blocking component 310: In Embodiment 1, the first driving component 313 uses a rotary cylinder to directly drive the first blocking component 311 and the second blocking component 312 to rotate. In this embodiment, the first driving component 313 uses a stepper motor in conjunction with a worm gear mechanism. Specifically, the output shaft of the stepper motor is connected to a worm, which meshes with a worm wheel fixed on the rotating shaft of the blocking component. By controlling the rotation angle of the stepper motor, precise control of the rotation position of the blocking component can be achieved, thereby allowing for more precise adjustment of the aperture size of the accommodating space to accommodate storage unit specifications with small diameter differences (e.g., storage units with a diameter difference of only 5-10 mm). Simultaneously, the worm gear mechanism has a self-locking characteristic, maintaining the position of the blocking component even in the event of a power outage, thus improving system safety. Regarding the adjustment structure of the collection mechanism 500: In Embodiment 1, the frame 510 of the collecting mechanism 500 has a fixed size, suitable for storage units within a specific diameter range. In this embodiment, the collecting mechanism 500 is also provided with a diameter adjustment mechanism. Specifically, the frame 510 is composed of multiple arc-shaped petals, each of which is connected to a fixed ring via a radial adjusting screw. By synchronously rotating each adjusting screw, the inner diameter of the frame 510 can be changed, thereby accommodating storage units of different diameters. The limiting rod 520 is also correspondingly configured to be radially movable. Furthermore, the extension length of the movable part 531 of the one-way check assembly 530 can also be adjusted by adjusting screws to ensure that storage units of different diameters can be reliably locked in place.

[0060] A centering guide horn is also provided at the lower part of the collecting mechanism 500. This horn can move up and down by being driven by a cylinder. When the storage unit is lifted by the transfer mechanism 400, the centering guide horn descends, and its inner conical surface guides the storage unit to automatically center, ensuring that the storage unit is concentric with the collecting mechanism 500, thereby avoiding jamming or stacking tilt caused by positional deviation.

[0061] The beneficial effects of this embodiment are as follows: the stepper motor and worm gear drive provides higher adjustment accuracy and self-locking safety; the adjustable diameter collection mechanism 500 enables the same device to handle a wider range of storage units without replacing hardware, thus improving the versatility and flexible production capabilities of the device.

[0062] Other general instructions It should be noted that, without departing from the core concept of this invention, the technical features in the above three embodiments can be combined with each other. For example, the multi-specification extension structure of Embodiment 2 can be combined with the adjustable diameter collection mechanism of Embodiment 3 to form a highly flexible device that can handle multiple specifications and flexibly adapt to different diameters.

[0063] Example 4 This embodiment, based on embodiments 1-3 above, further elaborates on the universality and adaptability adjustment method of the device of the present invention for storage units 600 of various specifications and shapes. In practical applications, the materials to be processed are not limited to SMT trays, but can also be electronic component carrier trays, pharmaceutical blister packs, small parts boxes, and other storage units 600 with similar planar structures that need to be stacked.

[0064] When the type or specifications of the storage unit 600 change, only the following adjustments to the size and positioning device are required, without altering its core working principle and overall structure: Adjustment of the guide mechanism 200: By adjusting component 222, the installation height of guide 221 and the opening distance of the input end horn are changed to match the height and width characteristics of the new memory cell, ensuring that only memory cells with specific shapes can be guided to the predetermined path. For example, when processing chip carriers with small heights, the height of guide 221 can be lowered to effectively contact and guide the carrier.

[0065] Adjustment of the separation mechanism 300: Based on the diameter or maximum profile size of the new storage unit 600, the rotation angles of the first blocking member 311 and the second blocking member 312 are adjusted to change the aperture of the accommodating space. Simultaneously, the mounting height and trigger threshold of the sensor in the first detection assembly 330 are adjusted to accurately identify the specifications or shapes of different storage units 600. For example, when processing parts boxes with larger diameters, the angle of the opposite rotation of the first blocking member 311 and the second blocking member 312 is increased to expand the accommodating space.

[0066] Adjustment of the transfer mechanism 400: Based on the bottom structure and edge features of the new storage unit 600, the grippers 430 are replaced or adjusted so that the first support portion 431 can stably support the body of the storage unit 600, and the second limiting portion 432 can precisely abut against its edge or a specific positioning structure. For example, for a flat storage unit without a flange, grippers with a larger support area and a higher limiting sidewall can be replaced.

[0067] Adjustment of the collection mechanism 500: By radially adjusting the position of the limiting rod 520, the diameter of the internal accommodating space of the frame body 510 is changed; simultaneously, the extension length of the movable part 531 of the one-way check assembly 530 and the preload of the elastic element are adjusted to ensure reliable support of the new storage unit from below. For example, when stacking heavier metal boxes, a more elastic element can be selected.

[0068] Through the simple and operable size and positioning adjustments described above, this equipment can efficiently process various storage units 600 of different specifications and shapes without the need to redesign and manufacture dedicated equipment, fully demonstrating the advanced nature and strong versatility of its structural design.

[0069] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
