Description

Technical Field

[0001] This invention relates to the field of USB socket assembly technology, and in particular to an automatic USB socket assembly device. Background Technology

[0002] USB socket automated assembly equipment is a key piece of automated equipment for achieving efficient production of electronic connectors. Its overall structure typically consists of core modules such as a feeding mechanism, a shifting mechanism, and an assembly mechanism, all integrated on a unified workbench. The feeding mechanism is responsible for orienting and conveying components such as housings and terminals using vibratory feeders and feeding tracks; the shifting mechanism is responsible for sequentially transferring the housings to designated assembly stations; and the assembly mechanism completes the precision pressing and assembly between the terminals and housings at the target station. This type of equipment widely adopts a modular layout, using cylinders, slide rails, motors, and other drive components to coordinate the actions of each stage, ultimately achieving fully automated assembly of the connector core, terminals, and housing, significantly improving production efficiency and product consistency.

[0003] However, the common practice in existing shifting mechanisms of directly pushing the outer casing using a slot-type shifting plate presents a key technical challenge: to ensure the positioning accuracy of the shift endpoint, a small mating gap must be maintained between the slot and the outer casing. However, during the upward reset process of the shifting plate, the friction generated between the inner wall of the slot and the side of the outer casing can easily cause a slight displacement of the positioned outer casing. Although this displacement is small, it can interfere with the accurate insertion of subsequent terminals, affecting not only the success rate of single assembly but also, in the long run, leading to fluctuations in yield and unstable production cycle, thus hindering further improvements in the overall performance of the equipment.

[0004] Therefore, there are still shortcomings and deficiencies in the existing technology, and how to provide an automatic assembly device for USB sockets is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic assembly device for USB sockets, which solves the technical problem that in the existing automatic assembly process of USB sockets, the friction generated between the slot of the shifting mechanism and the outer shell component due to the tight fit may cause the outer shell to undergo slight displacement when the shifting plate rises, thereby affecting the accuracy of subsequent terminal installation.

[0006] To achieve the above objectives, the present invention provides an automatic assembly device for USB sockets, including a base and a slide fixed to a workbench, and a shifting component that is driven to move vertically by a longitudinal moving component and to move laterally by a transverse moving component. The shifting component is disposed above the slide and is used to transfer the outer shell on the slide to the installation station. The shifting component includes a plate, a sliding plate, and an elastic pressure plate assembly. The plate is fixed to the output end of the longitudinal moving component.

[0007] The slide plate is movably connected to the front end of the plate body by a vertically arranged elastic member, and the bottom of the slide plate is provided with a slot for accommodating the outer shell;

[0008] The elastic pressure plate assembly is disposed on the slide plate and is used to apply a downward clamping force to the outer shell in the slot after the outer shell is transferred to the work station by the slot. The clamping force applied by the elastic pressure plate assembly during the upward movement of the displacement component continues until the slot is completely separated from the outer shell and then released.

[0009] Preferably, the slide is connected to the board body via a guide limiting member. The guide limiting member includes a slide rod fixed to the upper end of the slide and a slide sleeve fixed to the board body. The slide rod is slidably inserted into the slide sleeve, and the elastic element is sleeved on the outside of the slide rod.

[0010] Preferably, the elastic pressure plate assembly includes a lower pressure plate, a lower pressure spring, and a locking member. The lower pressure plate is longitudinally slidably disposed in the movable groove at the front end of the slide plate, and its bottom can extend into the slot above. The lower pressure spring is disposed between the lower pressure plate and the top wall of the movable groove to provide downward pressure to the lower pressure plate. The locking member is used to lock the lower pressure plate in the initial position in the movable groove during the downward movement of the displacement member.

[0011] Preferably, the locking component includes a connecting block disposed on the top of the lower pressure plate, a swing rod rotatably disposed on the slide plate, and a guide groove and guide rod mating structure disposed between the connecting block and the swing rod; when the housing enters the slot and pushes up the lower pressure plate, the swing rod can be driven to rotate through the mating of the guide groove and guide rod to release the locking of the lower pressure plate.

[0012] Preferably, the guide groove is a closed-loop groove formed on the connecting block, and its trajectory includes a vertical section, a descending guide section, a first height guide section, a first height locking point, a second height guide section, and a return section.

[0013] Preferably, the lower pressure plate is connected to the top wall of the movable groove via a limiting rod. The lower end of the limiting rod is fixed to the lower pressure plate, and the upper end is slidably inserted into the insertion hole in the top wall of the movable groove. The lower pressure spring is sleeved on the outside of the limiting rod.

[0014] Preferably, it further includes a reset member disposed on the base, the reset member including a reset wedge with an inclined surface, and a guide shaft fixed on the lower pressure plate; when the displacement member moves horizontally to reset, the guide shaft can slide along the inclined surface of the reset wedge to forcibly lift the lower pressure plate to its locked position.

[0015] Preferably, there are multiple reset wedges, which are arranged at equal intervals along the length of the shift plate, and the spacing between them is consistent with the spacing between the slots on the slide plate.

[0016] Preferably, the bottom entrance of the card slot is provided with a sloping surface that expands to both sides.

[0017] Preferably, the vertical segment extends vertically downward from the top of the connecting block, and its end connects to the descending guide segment in a smooth transition manner. The descending guide segment extends downward along the length direction of the connecting block and is inclined downward. The bottom of the descending guide segment extends horizontally to connect to the first height guide segment, which extends upward along the width direction of the connecting block and is inclined upward until it reaches the first height locking point.

[0018] The second height guide section starts from the first height locking point, extends along the width of the connecting block and tilts towards the bottom; the return section extends straight upward from the end of the second height guide section, and connects at the top with the starting intersection of the vertical section and the descending guide section through an arc-shaped connecting part, thereby forming a continuous closed loop trajectory.

[0019] The present invention has the following advantages:

[0020] (1) Compared with the above-mentioned background technology, the automatic assembly equipment for USB sockets provided by the present invention effectively solves the problem of misalignment caused by friction between the slot and the workpiece during assembly by introducing a composite shifting mechanism with an elastic pressure plate and a reset component. Its core lies in realizing the timing control of "pressing first and then disengaging": when the shifting plate rises, the elastic pressure plate can continuously apply downward pressure to the outer shell until the slot is completely disengaged, thereby offsetting the lateral force caused by friction of the inner wall of the slot and ensuring that the workpiece maintains accurate positioning after the transfer is completed. This not only improves the alignment accuracy of the terminal and the outer shell and the assembly yield, but also realizes automatic pressure control through a purely mechanical structure, avoiding the introduction of complex sensing or program systems, and enhancing the stability and reliability of the equipment under high-speed continuous operation.

[0021] (2) Compared with the above-mentioned background technology, the automatic assembly equipment for USB sockets provided by the present invention utilizes the guide groove trajectory and the reset wedge to realize the automatic cyclic reset of the pressure plate, thereby improving the automation level and production efficiency of the equipment. During the horizontal reset movement, the shift plate automatically lifts the lower pressure plate and relocks it to the preset height through the cooperation of the guide shaft and the inclined surface of the wedge, preparing for the next transfer without the need for an additional power source or manual intervention. This not only simplifies the operation process and ensures the continuity of the production cycle, but also its modular design has strong adaptability. It can adapt to the production needs of different specifications of products by adjusting the wedge spacing or the guide groove trajectory, thereby improving the flexibility of the equipment.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This invention provides an automatic assembly device for USB sockets. By controlling the timing of "pressing first and then disengaging" and automatic reset, it effectively eliminates workpiece misalignment caused by friction during the transfer process. This improves assembly accuracy and yield while achieving efficient and stable automated cyclic production. Furthermore, it solves the problem that friction between the slot of the shifting mechanism and the outer shell component during the automatic assembly of USB sockets can cause slight displacement of the outer shell when the shifting plate rises, thus affecting the accuracy of subsequent terminal installation.

[0041] Please refer to this as well. Figures 1 to 14The automatic assembly equipment for USB sockets provided by this invention mainly consists of a feeding mechanism 1, a shifting mechanism 3, and an installation mechanism 2 working together. All these components are mounted on a workbench to achieve efficient and precise assembly of the casing and terminals. The feeding mechanism 1 is responsible for supplying key components such as the casing and terminals required for assembly. Its specific components typically include an unwinding assembly and a slitting assembly, which are mature existing technologies in this field and will not be detailed here. During batch assembly, the shifting mechanism 3 is responsible for sequentially transferring each casing to a designated installation station, where the installation mechanism 2 precisely inserts the terminals into the casing. Therefore, the positioning accuracy and movement stability of the shifting mechanism 3 directly determine the alignment effect between the terminals and the casing and the reliability of the overall assembly, making it a core element in ensuring the smooth operation of the entire automated process and the quality of the final product.

[0042] In existing technologies, such as Figures 1-5 As shown, the shifting mechanism 3 is typically composed of a base 301, a slide 302, a longitudinal moving member 303, a transverse moving member 304, and a shifting member 305. The base 301 and the slide 302 are both fixedly mounted on the worktable of the equipment. The USB casing component from the feeding mechanism 1 is conveyed onto the slide 302. The shifting member 305 is positioned above the slide 302. It moves vertically via the longitudinal moving member 303 and horizontally via the transverse moving member 304. Through the coordination of these longitudinal and transverse movements, the casing component on the slide 302 is accurately moved to the designated installation position, achieving precise horizontal positioning.

[0043] Specifically, the lateral moving component 304 mainly includes a horizontal push rod 341, a sliding component 342, and a horizontal moving seat 343. The horizontal push rod 341 is horizontally fixed to the front end face of the base 301 via a mounting bracket. The horizontal moving seat 343 is horizontally slidably connected to the front end of the base 301 via the sliding component 342. The sliding component 342 generally includes a slide rail and a slider. The slide rail is fixed to the front end of the base 301, and the slider is installed at the rear end of the horizontal moving seat 343. The two form a sliding engagement, driving the horizontal moving seat 343 to move laterally along the slide rail. One end of the horizontal moving seat 343 is fixed to the extension shaft of the horizontal push rod 341. When the horizontal push rod 341 extends or retracts, it can directly drive the horizontal moving seat 343 to move laterally, thereby driving the longitudinal moving component 303 and the displacement component 305 installed at its front end to move laterally as a whole, realizing the adjustment of the original position.

[0044] The longitudinal moving component 303 mainly includes a fixed base 331, a longitudinal push rod 332, and a longitudinal moving seat 333. The fixed base 331 is installed at the front end of the horizontal moving seat 343, and the longitudinal push rod 332 is fixed above the fixed base 331, with its telescopic shaft extending vertically downwards. The front end of the fixed base 331 is longitudinally slidably connected to the longitudinal moving seat 333 via another set of sliding parts 342, while the end of the extended shaft of the longitudinal push rod 332 is fixed to the top of the longitudinal moving seat 333, allowing the longitudinal moving seat 333 to move precisely vertically under the control of the longitudinal push rod 332. The displacement component 305 is installed at the front end of the longitudinal moving seat 333. Through the coordinated action of the longitudinal push rod 332 and the horizontal push rod 341, the displacement component 305 achieves a combined displacement in both the longitudinal and lateral directions.

[0045] like Figures 4-7 As shown, the shifting component 305 consists of a shifting plate 351 and slots 352 formed thereon. The shifting plate 351 is fixed to the front end of the longitudinal moving seat 333, and its lower end face has multiple slots 352 arranged in a straight line at equal intervals along the original part conveying direction. The width of the slots 352 matches the width of the original part, and the spacing between the slots is consistent with the working conveying length of the original part. During shifting, the central controller of the equipment drives the longitudinal push rod 332 and the horizontal push rod 341 in sequence: First, the longitudinal push rod 332 moves, causing the longitudinal moving seat 333 to move downward, so that the shifting plate 351 approaches the slide table 302, and the slots 352 are embedded in the outside of the original part; then the horizontal push rod 341 starts, pushing the horizontal moving seat 343 to move a set distance along the next working position, thereby causing the fixed seat 331, the longitudinal moving seat 333 and the shifting plate 351 to move laterally as a whole. Through the drive of the slots 352, the original part of the original part on the slide table 302 is synchronously pushed to the next working position. After the transfer is completed, the longitudinal push rod 332 drives the shift plate 351 to move upward, so that the slot 352 is separated from the original part. Then the horizontal push rod 341 drives the shift mechanism 3 to return to the initial position, ready to perform the next shift operation.

[0046] In the original design, the shift plate 351 was directly driven to descend by the longitudinal push rod 332. If the descent speed was too fast or the positioning was slightly off, the rigid slot 352 might collide hard with the outer shell, causing the delicate outer shell to be deformed or even damaged under pressure. To solve this problem, this embodiment has made significant optimizations to the structure of the shift plate 351.

[0047] Specifically, such as Figures 4-8As shown, the shifting plate 351 is designed as a composite buffer mechanism comprising a plate body 3511, a sliding plate 3512, and an elastic element 3513. The plate body 3511 is directly fixed to the front end of the longitudinal moving seat 333, while the slot 352 for accommodating and pushing the outer shell is not directly formed on the plate body 3511, but precisely formed at the bottom end of the independent sliding plate 3512. On the front face of the plate body 3511, multiple grooves 4 are equidistantly formed along its length, with a corresponding clearance groove 5 extending through the front and rear of the plate body 3511 directly below each groove 4. The sliding plate 3512 is slidably inserted into the groove 4, with its bottom portion containing the slot 352 extending out from the clearance groove 5. A stop block 6 is fixed to the top of the groove 4, and the stop block 6 is connected to the sliding plate 3512 via the elastic element 3513, providing continuous elastic support for the sliding plate 3512. To further ensure the smooth movement of the skateboard 3512, a guide and limiting component consisting of a sliding sleeve 7 and a sliding rod 8 is provided between the stop block 6 and the skateboard 3512, effectively preventing the skateboard 3512 from tilting or coming off during operation. The elastic component 3513 can be set as a spring and sleeved on the outside of the sliding rod 8.

[0048] Based on the above structure, when the shifting plate 351 descends as a whole, if the outer shell and the slot 352 are properly aligned, the sliding plate 3512 will smoothly fit into the outer shell. If there is a positional deviation, the sliding plate 3512 will contact the outer shell first. At this time, the elastic element 3513 can immediately compress to absorb the impact energy, thereby avoiding damage to the outer shell caused by rigid collision. In addition, the bottom entrance of the slot 352 is designed as an enlarged sloping surface opening to both sides. This guide slope can smoothly guide the slightly deviated outer shell to the center of the slot 352 at the moment of contact. Together with the elastic buffer above, it forms a dual protection mechanism of "guiding first and then buffering", which improves the reliability of the transfer action and the protection of the workpiece.

[0049] Although the aforementioned method of directly pushing the outer casing through the slot 352 simplifies the clamping process, eliminating the need for additional vacuum suction or dedicated grippers and reducing the complexity of the control system and program, while avoiding independent control links for clamping and releasing, this transfer method inherently presents a key contradiction in actual high-speed, high-precision automated assembly: to ensure the accuracy of the transfer endpoint, the fit gap between the slot 352 and the outer casing must be minimized to achieve precise guidance and positioning. However, this tight fit, designed for precision, results in significant and unavoidable frictional contact between the inner wall of the slot 352 and the side of the outer casing during the transfer and upward reset of the shift plate 351. This frictional force exerts a reverse effect along the transfer direction of the outer casing, causing a slight, unexpected displacement or deflection of the already positioned outer casing. Such seemingly micron-level deviations are fatal in precision assembly. They directly affect the alignment of subsequent precision components such as terminals when they are inserted into the housing. This can not only lead to single assembly failures, but also accumulate as the equipment continues to run, ultimately resulting in fluctuations in product yield and instability in production cycle time, thus restricting the efficient and reliable operation of the entire automated system.

[0050] In this embodiment, as Figures 4-7 , Figure 9 as well as Figure 10 As shown, to fundamentally eliminate the risk of workpiece misalignment caused by friction between the inner wall of the slot 352 and the outer shell during the upward movement of the shift plate 351, an elastic pressure plate assembly 9 is specially added. This assembly is installed directly above the slot 352 of the slide plate 3512. Its core function is to immediately apply a continuous and controllable downward vertical pressure to the outer shell component within the slot 352 after the outer shell is transferred to the target station. This pressure remains in effect after the entire transfer process is completed, ensuring that even if the shift plate 351 begins to rise and friction occurs between the side wall of the slot 352 and the outer shell, the outer shell can be firmly and stably held in the predetermined position. The key lies in the timing control of the pressure: this clamping force continues until the shift plate 351 rises to a safe height where the inner wall of the slot 352 is completely out of contact with the outer shell, at which point the pressure is released. Through this coordinated action mechanism of "first clamping, then releasing," the positioning accuracy at the transfer endpoint and the continuous stability of the entire automated assembly process are significantly improved.

[0051] In specific implementation, such as Figures 4-7 , Figure 9 as well as Figure 10As shown, the elastic pressure plate assembly 9 mainly consists of a lower pressure plate 901, a lower pressure spring 902, and a locking member 903. The front end face of the sliding plate 3512 has a movable groove 11 that is closed at the top and open at the bottom. The lower pressure plate 901 is slidably inserted into this movable groove 11 and can move longitudinally. Its bottom extension is located in the upper space inside the slot 352. When the slot 352 is not engaged with the outer shell, the locking member 903 locks the lower pressure plate 901 at a predetermined height within the movable groove 11. At this time, the lower pressure spring 902 is in a compressed, energy-stored state. This ensures that during the descent of the shift plate 351, the lower pressure plate 901 will not prematurely contact the outer shell, thus avoiding the possibility that premature pressure application might hinder the slot 352 from guiding and aligning the outer shell through its inclined opening.

[0052] When the shift plate 351 descends into position and the slot 352 successfully engages with the outer shell, the movement of the outer shell into the slot 352 contacts and triggers the locking element 903, causing it to release automatically. The pressure plate 901 then moves downwards under the drive of the pressure spring 902, its lower end face ultimately providing continuous downward pressure on the top of the outer shell, thus firmly pressing it into place after it has been moved. During the subsequent ascent of the shift plate 351, although the inner wall of the slot 352 will rub against the outer shell, the pressure provided by the pressure plate 901 remains, effectively preventing the outer shell from shifting or deflecting. The pressure plate 901 only separates from the outer shell when the shift plate 351 rises to the position where the slot 352 is completely detached from the outer shell, thus achieving delayed pressure release and ensuring the reliability and accuracy of the entire transfer and positioning process.

[0053] To meet the precise movement requirements of the elastic pressure plate assembly 9, a specially designed limiting rod 12 ensures reliable longitudinal movement guidance and limitation between the lower pressure plate 901 and the top wall of the movable groove 11. The lower end of the limiting rod 12 is fixedly connected to the upper end face of the lower pressure plate 901, while its upper end is inserted into a pre-set insertion hole in the top wall of the movable groove 11. This ensures that the lower pressure plate 901 maintains a strict longitudinal trajectory during movement, preventing any lateral deviation or jamming. To further enhance reliability, a stepped structure is designed at the mating point between the limiting rod 12 and the insertion hole. This structure effectively prevents the limiting rod 12 from accidentally dislodging from the insertion hole, playing a crucial anti-dislodgement role. The downward pressure spring 902, used to provide downward pressure, is tightly fitted around the limiting rod 12, ensuring that the transmission of spring force remains consistent with the movement axis of the lower pressure plate 901.

[0054] The core function of locking component 903 is to automatically switch the working states of the lower pressure plate 901, such as... Figures 9-11As shown, its specific structure includes a connecting block 931, a rotating shaft 932, a swing rod 933, a guide groove 934, and a guide rod 935. The connecting block 931 is fixedly installed on the top of the lower pressure plate 901. A rotatable rotating shaft 932 is provided at the front end of the top of the slide plate 3512, and a swing rod 933 is fixed to one end of the rotating shaft 932. The bottom end of the swing rod 933 extends downward to the front side of the connecting block 931, and a guide groove 934 of a specific shape is machined on the front end surface of the connecting block 931. A guide rod 935 is fixed to the rear end face of the bottom end of the swing rod 933 and is inserted into the guide groove 934 to cooperate with it. The guide groove 934 is specially designed, and its core function is as follows: when the slot 352 successfully fits into the outer shell and causes a slight upward displacement of the lower pressure plate 901, this slight movement will drive the guide groove 934 to generate a relative displacement through the connecting block 931, forcing the internal guide rod 935 to move along the groove shape, thereby driving the swing rod 933 to rotate around the rotation axis 932. This rotation will eventually release the mechanical constraint of the locking member 903 on the height of the lower pressure plate 901. Once the constraint is released, the pre-compressed and energy-stored lower pressure spring 902 is released, and its elastic force will drive the lower pressure plate 901 to move downward as a whole, so that its lower end face presses against and stably contacts the outer shell, thereby continuously applying pressure during the subsequent upward movement of the shift plate 351 until the slot 352 is completely disengaged, thus ensuring the absolute stability of the outer shell positioning.

[0055] The guide groove 934 is a continuous, smooth closed-loop structure, composed of several functionally defined segments connected sequentially. For example... Figures 9-12 As shown, its trajectory begins at the top of the connecting block 931 with a vertical segment 9341, which is a straight groove running vertically downwards. The end of the vertical segment 9341 connects to a descending guide segment 9342, where the groove begins to change direction, extending approximately along the length of the connecting block 931 while simultaneously sloping downwards. After reaching the bottom, the sloping descending guide segment 9342 turns and extends horizontally for a short distance along the width of the connecting block 931, then smoothly connects to the first height guide segment 9343. The path of the first height guide segment 9343 includes both a width component and a component sloping upwards, making it appear as an ascending ramp. This ramp extends to approximately the middle of the width of the connecting block 931, reaching a critical turning point—the first height locking point 9344.

[0056] like Figures 12-13As shown, starting from the first height locking point 9344, the path transitions to the second height guide segment 9345, which follows the opposite direction to the first height guide segment 9343, extending along the width direction while gradually sloping downwards. After extending to the other side of the width direction, the second height guide segment 9345 connects to the final segment—the return segment 9346. The path of the return segment 9346 extends straight upwards along the length of the connecting block 931, eventually forming an arc at the top region that extends along the width direction of the connecting block 931, connecting with the starting point of the vertical segment 9341 and the descending guide segment 9342, thus forming a complete closed loop.

[0057] It is particularly important to note that at the intersection of the vertical section 9341, the descending guide section 9342, and the return section 9346, the connection between the vertical section 9341 and the descending guide section 9342 is designed as a near-straight, smooth transition. This ensures that the guide rod 935 naturally enters the descending guide section 9342 rather than the return section 9346 during descent; and when the guide rod 935 rises along the return section 9346, it is smoothly guided into the vertical section 9341. All sections of the guide groove 934 are interconnected, and all connections are rounded to ensure the smooth operation of the guide rod 935.

[0058] The working principle and state transition of this structure are as follows: When the guide rod 935 is at the top of the vertical section 9341, it indicates that the compression spring 902 is in the released state, and the pressure plate 901 is at the lowest point of its stroke, with its bottom surface lower than the bottom surface of the slide plate 3512. When a workpiece needs to be picked up and the pressure plate 901 moves upward, the relative movement path of the guide rod 935 in the slot is as follows: First, it descends from the top of the vertical section 9341, and after passing the intersection point, it naturally enters the descending guide section 9342, moving along its inclined path to the inflection point connected to the first height guide section 9343, and is then guided into the first height guide section 9343, which is trending upward. At the end of the first height guide section 9343, the path, guided by the first height guide section 9343, finally pushes the guide rod 935 to the first height locking point 9344. At this time, the pressure plate 901 is mechanically locked at a preset height inside the slot 352.

[0059] At this preset height, the distance between the bottom surface of the pressure plate 901 and the bottom surface of the slide plate 3512 is less than the height of the original housing. Therefore, when the shift plate 351 continues to descend, allowing the slot 352 to successfully fit into the housing, the top of the housing will contact the pressure plate 901 and apply an upward force to it. This force causes the connecting block 931 (and guide groove 934) to produce a slight upward displacement relative to the fixed guide rod 935. It is this displacement that causes the guide rod 935 to release from the locked first height locking point 9344 and be guided to move along the descending ramp of the second height guide section 9345 until it reaches the inflection point between the second height guide section 9345 and the return section 9346. After reaching this position, the vertical position of the guide rod 935 is no longer mechanically constrained, and the locking state of the pressure plate 901 is released. Therefore, the previously compressed and stored energy of the downward pressure spring 902 is fully released, driving the downward pressure plate 901 to move downward, so that its bottom surface presses firmly against the outer casing, providing the necessary retaining downward pressure. It should be emphasized that the elasticity of the downward pressure spring 902 needs to be carefully adjusted. Its size should be such that it can stably maintain the position of the outer casing, and should not be too large, so as not to hinder the smooth sliding of the outer casing during transportation due to excessive friction.

[0060] After the outer casing is transferred to the target station and one step transfer is completed, the shifting plate 351 begins to rise. Since the lower pressure plate 901 is completely released from its mechanical lock at this point, and is only subjected to the elastic force of the lower pressure spring 902, the lower pressure plate 901 can consistently press the top of the outer casing against the vertical pressure continuously provided by the lower pressure spring 902. This continuous pressure remains effective throughout the entire process of the slot 352 rising and gradually separating from the outer casing, thus forming a stable holding force when relative friction occurs between the side walls of the two components. This effectively resists workpiece displacement or deflection that may be caused by friction, ensuring the positional accuracy and stability of the outer casing after the transfer is completed.

[0061] After completing this transfer and releasing the lower platen 901 to its lowest position, in order for it to automatically reset to the preset height and repeat the next transfer task, as follows: Figures 4-6 as well as Figure 14As shown, in this embodiment, a reset component 10 connected to the equipment base 301 is provided at the rear end of the shift plate 351. The reset component 10 mainly includes an L-shaped connecting frame 1001, a series of reset wedges 1002, and a guide shaft 1003 mounted on each lower pressure plate 901. The connecting frame 1001 is directly fixed to the base 301, and the reset wedges 1002 are fixed to the end of its horizontal extension. Multiple reset wedges 1002 are provided and are equidistantly arranged along the length of the shift plate 351, with their spacing completely corresponding to the spacing of the slots 352 on the shift plate 351. The upper surface of each reset wedge 1002 is machined as an inclined guide slope. After the transfer is completed and the shift plate 351 rises to a predetermined height, the guide shaft 1003 fixed to the rear end of each lower pressure plate 901 moves precisely to the lower starting position of the corresponding reset wedge 1002's inclined surface. When the shift plate 351 performs a horizontal reset movement, the guide shaft 1003 will move upward along the inclined surface of the reset wedge 1002. This inclined surface movement will be converted into an upward lifting force on the lower pressure plate 901, forcing the lower pressure plate 901 to move upward against the spring force. The upward movement of the lower pressure plate 901 causes a change in the relative position of the guide rod 935 fixed to it in the guide groove 934. Specifically, the guide rod 935 starts from the top of the vertical section 9341, moves downward along the designed trajectory, naturally enters the descending guide section 9342 through the intersection point, and is finally guided to the inflection point connected to the first height guide section 9343. As the shift plate 351 continues to move horizontally, the guide shaft 1003 eventually moves out of the reset wedge block 1002 area. At this time, the elastic force of the pressure spring 902 is released, pushing the guide rod 935 into the first height guide section 9343, which is trending upward, and finally reaching and stabilizing at the first height locking point 9344. This re-locks the pressure plate 901 at the preset working height above the slot 352, preparing for the next precise gripping and transfer cycle.

[0062] In this embodiment, during operation: the entire cycle begins with the shifting plate 351 descending with the locked elastic pressure plate assembly 9. When the slot 352 approaches the workpiece, if there is a misalignment, the inclined guide structure at the bottom of the slide plate 3512 will first contact the workpiece and guide it to the center of the slot 352. At the same time, the elastic element 3513 on the slide plate 3512 can be compressed to absorb the impact and avoid hard contact damage to the workpiece. As the shifting plate 351 continues to descend until the slot 352 is completely fitted into the outer shell, the top of the workpiece will touch the still locked lower pressure plate 901 and apply a small upward force. This force is transmitted through the connecting block 931 to its internal guide groove 934, forcing the guide rod 935 connected to the swing rod 933 to move along a specific groove trajectory, thereby driving the swing rod 933 to rotate and finally releasing the mechanical lock on the lower pressure plate 901. After the lock is released, the lower pressure plate 901 immediately moves downward under the drive of the lower pressure spring 902, firmly pressing its bottom surface against the top of the outer shell.

[0063] Subsequently, the lateral moving component 304 is activated, propelling the entire shifting mechanism 3, along with the outer casing workpiece constrained by the slot 352 and the lower pressure plate 901, precisely to the target installation position. After the transfer is completed, the shifting plate 351 begins to rise. During this crucial stage, although friction occurs between the inner wall of the slot 352 and the side of the outer casing due to their tight fit, this friction is effectively counteracted because the lower pressure plate 901 has been unlocked and continuously applies a vertically downward clamping force. This ensures that the outer casing remains stationary at the workstation without any deviation. The shifting plate 351 continues to rise until the slot 352 is completely disengaged from the workpiece, at which point the lower pressure plate 901 separates from the workpiece, achieving delayed pressure release and ensuring the final positioning accuracy.

[0064] In preparation for the next transfer cycle, during the horizontal resetting movement of the shift plate 351, the guide shaft 1003 fixed to the rear end of its lower pressure plate 901 contacts the inclined surface of the reset wedge block 1002 fixed on the base 301. Through the relative motion generated by the horizontal movement, the guide shaft 1003 moves upward along the inclined surface, thereby forcibly lifting the lower pressure plate 901, compressing the lower pressure spring 902, and driving the guide rod 935 to slide along the descending guide section 9342 within the closed-loop guide groove 934. Finally, guided by the first height guide section 9343, it stabilizes again at the first height locking point 9344, relocking the lower pressure plate 901 at the preset working height. At this point, the shift mechanism 3 completes a full work cycle, all components are reset, and it is ready to perform the next high-precision, high-reliability transfer operation.
