Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and more specifically, to a pen clip assembly fixture and pen clip assembly equipment. Background Technology

[0002] Pens, especially mid-to-high-end fountain pens and ballpoint pens, typically feature a clip on the cap. This clip not only serves the practical function of preventing the pen from slipping out of a pocket but also functions as an important decorative element. Modern pen clip designs are becoming increasingly complex and sophisticated, with one common structure consisting of a clip body and a separate decorative element. The clip body usually features a U-shaped groove and a through-hole, and the decorative element needs to be precisely fitted into this U-shaped groove.

[0003] In existing technologies, the assembly of such pen clips largely relies on manual operation or simple clamps. The operator must first insert the second end of the decorative piece into the U-shaped groove of the pen clip body, then use tools or their hands to pry open the elastic first end of the decorative piece, and finally press it into the opening of the groove to complete the snap-fit. However, this traditional assembly method has many drawbacks: Poor assembly accuracy and low efficiency: Due to the small size and delicate structure of the decorative parts and pen clip, manual alignment is difficult, resulting in inaccurate assembly positions, poor product consistency, and low production efficiency, making it difficult to meet the needs of mass production.

[0004] Product is easily damaged: During the process of manually opening and pressing the decorative parts, the force applied by the operator is not easy to control, which can easily leave scratches and indentations on the surface of the decorative parts, or cause permanent plastic deformation or even breakage of the decorative parts or pen clip body due to excessive force, resulting in high waste losses.

[0005] Automation is difficult to achieve: Traditional tooling lacks effective guidance and positioning structures, and cannot cooperate stably and reliably with automated equipment (such as robotic arms and pressing devices), making it difficult to upgrade the entire assembly process to automation.

[0006] Therefore, there is an urgent need in the field for a pen clip assembly tooling and equipment that can achieve precise positioning, provide stable guidance, effectively protect products from damage, and seamlessly integrate with automated equipment, in order to solve the aforementioned long-standing technical problems. Summary of the Invention

[0007] This invention aims to provide a pen clip assembly fixture and a pen clip assembly device. The fixture is capable of precisely positioning and guiding the pen clip body and decorative parts to ensure assembly quality and consistency. Furthermore, it provides a pen clip assembly device incorporating this fixture, enabling efficient automated assembly.

[0008] To achieve the above objectives, in a first aspect, the present invention provides a pen clip assembly fixture for assisting in the assembly of a pen clip. The pen clip includes a main body and a decorative component. The main body has a first groove, a second groove, and a through hole. The decorative component is partially embedded in the first and second grooves. The decorative component is U-shaped and has a first end located at the opening of the U-shape and a second end away from the opening. The fixture includes: Base; The positioning groove is fixed on the base; A positioning post is fixed to the base and located within the positioning groove; A guide post is fixed to the base. The guide post has an upper end face and a lower end face. The lower end face faces the positioning post, and the upper end face is provided with a guide slope. The positioning post, the inner wall of the positioning groove, and the lower end face of the guide post together define a placement space for accommodating the main body. When the pen clip is assembled, the main body is placed in the placement space, the second end of the decorative piece is placed in the second groove, and the first end of the decorative piece is gradually opened and slid into the first groove by the guide slope.

[0009] By employing the above technical solution, the positioning post, the inner wall of the positioning groove, and the lower end face of the guide post work together to form a three-dimensional constraint space for the pen clip body, ensuring the absolute stability of the body during assembly. Crucially, the guide ramp on the guide post, in conjunction with the elastic deformation characteristics of the U-shaped decorative piece, creates a controlled, progressive assembly path. When the first end of the decorative piece contacts the guide ramp, its U-shaped structure is gradually expanded at a predetermined angle. This process decomposes the large-amplitude elastic deformation required by the decorative piece into multiple continuous, small-amplitude deformation stages, effectively avoiding plastic deformation or fracture caused by instantaneous stress concentration. This collaborative mechanism of "positioning-guiding-progressive deformation" solves the problem of simultaneously ensuring accuracy and avoiding damage in manual assembly, achieving high-quality, highly consistent assembly.

[0010] In some embodiments, the positioning post includes an integrally formed first post and a second post, the first post being used to engage with a through hole in the body, and the second post having a smaller diameter than the first post and being closer to the entrance of the positioning groove.

[0011] By adopting the above technical solution, this stepped double-column structure constitutes a precise two-stage positioning system. The second column, acting as a guide, has a smaller diameter that allows for greater positional deviation during the initial alignment of the main body's through-hole with the positioning column, enabling rapid, coarse alignment. Subsequently, the first column, acting as a fine positioning component, forms a tight clearance fit with the through-hole, ultimately eliminating all degrees of freedom and completing the precise positioning of the main body. This design integrates "coarse guidance" and "fine positioning" functions into a single component, significantly reducing the alignment difficulty and operational precision requirements when placing the main body into the tooling, and improving assembly speed.

[0012] In some embodiments, the outer end face of the second column is provided with a guide surface, which together with the second column forms a two-level guide structure for guiding the main body before it mates with the first column.

[0013] By adopting the above technical solution, the introduction of guiding surfaces (such as chamfers or arc surfaces) adds a more basic "pre-guiding" stage before the coarse guiding function of the second column. This allows the main body to be guided towards the axis of the second column at the very moment the end face of the main body's through-hole contacts the positioning column. This three-stage progressive positioning strategy of "pre-guiding-coarse guiding-fine positioning" further digests and corrects potential initial position errors step by step, ensuring that even main bodies with certain manufacturing tolerances can be smoothly and without interference guided to the final design position, greatly improving the adaptability of the tooling and the assembly success rate.

[0014] In some embodiments, the guide post further includes a slide rail connected to the guide ramp and to the lower end face, wherein when the decorative element slides down the guide ramp into the slide rail, the slide rail applies a thrust to the decorative element in a direction away from the second end.

[0015] By adopting the above technical solution, the design of the slide rail optimizes and extends the function of the single guide ramp. The guide ramp mainly completes the opening action of the decorative piece, while the slide rail is responsible for guiding the opened decorative piece to complete the final "returning" action. The specific geometry of the slide rail allows it to apply a horizontal component force to the decorative piece. This component force is precisely used to overcome the "rebound force" generated by the decorative piece's own elasticity, which attempts to return to its original state, and accurately "pushes" its first end into the first groove. This ensures that the decorative piece can accurately reach the final assembly position after leaving the guide mechanism, avoiding misassembly or jamming caused by rebound.

[0016] In some embodiments, when the body is placed in the placement space, the connection between the slide and the lower end face covers a portion of the body.

[0017] By adopting the above technical solution, this covering structure forms a physical constraint. Its core function is to connect with the first groove to smoothly guide the decorative piece into the first groove and prevent rebound. When the decorative piece slides rapidly into the first groove under the thrust of the slide rail, there is a risk that it may deviate from the predetermined trajectory due to inertia. This covering acts as a "baffle" or "limiter," intercepting this abnormal movement and ensuring that the endpoint of the decorative piece's movement is strictly limited within the first groove. It complements the thrust function of the slide rail; one actively "pushes," and the other passively "intercepts," jointly ensuring the finality and reliability of the assembly process.

[0018] In some embodiments, the base is further provided with an elastic element, which is located on opposite sides of the positioning post and the guide post, respectively. One end of the elastic element extends into the positioning groove and can exit the positioning groove under the action of external force.

[0019] By adopting the above technical solution, the elastic element and the rigid positioning structure (positioning pin, positioning groove) constitute a "rigid-flexible" clamping system. The rigid structure is responsible for the main positioning, while the elastic element provides a continuous, flexible lateral clamping force. This force has two key functions: first, when assembling decorative parts, it counteracts the lateral reaction force that the insertion of the decorative parts may generate on the main body, preventing the main body from micro-moving or rotating within the tooling and ensuring assembly accuracy; second, after assembly, its frictional force can temporarily "grip" the assembled parts, preventing them from accidentally falling out of the tooling due to gravity or vibration. Its retraction characteristic ensures the smooth progress of the material handling process.

[0020] In some embodiments, the elastic element includes a spring and an abutment, the abutment being connected to the spring and located within a positioning groove.

[0021] By adopting the above technical solution, the spring, as a pressure source, provides a controllable and recoverable elastic force. The abutment, as an actuating element, can be designed in terms of material and shape (such as using engineering plastics or having a rounded contact surface) to be friendly to the surface of the pen clip body, avoiding indentations or scratches. This modular design allows the clamping force to be adjusted by replacing springs of different specifications to accommodate pen clips of different models and weights, enhancing the versatility and adjustability of the tooling.

[0022] Secondly, the present invention also relates to a pen clip assembly device, including the pen clip assembly fixture described in the first aspect.

[0023] By adopting the above technical solution, the precision pen clip assembly fixture is integrated into automated equipment, enabling the accurate, reliable, and non-destructive assembly process achieved by the fixture to be stably reproduced in large-scale production. This equipment breaks down the complex assembly actions that originally relied on the hand-eye coordination of skilled workers into a standardized, programmable process completed collaboratively by the fixture, pressing device, and material handling device. This fundamentally ensures the consistency of product quality and achieves highly efficient continuous production.

[0024] In some embodiments, a pressing device is also included, the pressing device comprising: The pressure rod moves toward or away from the pen clip assembly fixture along a first direction; Two grippers, connected to the lowering rod, move relative to each other or away in a second direction; Wherein, the first direction and the second direction are perpendicular to each other. When the main body is placed in the pen clip assembly fixture for assembling decorative parts, the pressing rod corresponds to the middle part of the decorative part, and the two clamps correspond to the first end of the decorative part.

[0025] By adopting the above technical solution, the pressing device employs a composite motion strategy that combines "vertical pressing" and "horizontal clamping," cleverly matching the geometric characteristics and assembly mechanics requirements of the U-shaped decorative part. The pressing rod acts on the middle of the decorative part, providing the main driving force for insertion; the two grippers clamp the first end of the decorative part (usually the part pre-placed in the first groove) from both sides. Their core function is not to provide insertion force, but to prevent the first end from tilting, shifting, or coming out of the first groove during the pressing process, ensuring that the decorative part descends smoothly as a whole. This synergistic effect of "main drive - anti-drift" ensures that the movement of both ends of the decorative part is precisely synchronized, perfectly following the assembly trajectory set by the tooling guide ramp, making it a key actuator for achieving successful automated assembly.

[0026] In some embodiments, a material handling device is also included, the material handling device comprising: The material handling clamp is used to remove the assembled pen clip from the pen clip assembly fixture. The top component abuts against the decorative component before the material-grabbing clamp picks up the pen clip; The top material component is aligned with the center line of the material handling clamp.

[0027] By adopting the above technical solution, the design of the material handling device effectively solves the problem of non-destructive removal of finished products from high-precision, elastically clamped tooling. The function of the ejector component is "pre-release of constraints" and "auxiliary positioning." Before the material handling clamp moves, it first abuts against the pen clip (usually a decorative part), applying a small ejection force. This force is sufficient to overcome the residual clamping force of the elastic component on the pen clip body, allowing the pen clip to loosen slightly in the tooling without popping it out. This action also ensures the consistency of the decorative part's assembly position. Subsequently, the material handling clamp clamps along the same centerline. Throughout the process, the pen clip experiences clear force and its movement trajectory is controllable, effectively preventing damage, dropping, or jamming of the pen clip within the tooling due to improper material handling force, thus ensuring the continuity and reliability of the automated production process.

[0028] In summary, this application has at least one of the following beneficial technical effects: 1. By utilizing the coordinated spatial constraints of positioning posts, positioning grooves, and guide posts, and combining this with the progressive unfolding guidance of the guide slope on the U-shaped decorative component, an assembly environment integrating precise positioning, controllable deformation, and smooth introduction is constructed. This solution fundamentally solves the core problems of low efficiency, product damage, and poor consistency caused by inaccurate positioning and stress concentration in manual assembly.

[0029] 2. The multi-level progressive guiding and positioning system consisting of a guide surface, a second column, and a first column, along with the slide rail that applies horizontal thrust to the decorative parts and the cover design to prevent overshoot, work together to significantly improve the tooling's tolerance to part tolerances and the robustness of the assembly process, ensuring an extremely high success rate in high-speed automated production.

[0030] 3. The "rigid-flexible" design of the elastic clamping component and the rigid positioning structure, along with the composite motion strategy of "vertical downward pressing and horizontal anti-drift" in the pressing device, achieves dynamic and stable control of parts during assembly. This multi-dimensional and synergistic clamping and driving mechanism is key to achieving efficient and non-destructive automated assembly, demonstrating ingenious design that is not immediately obvious.

[0031] 4. The timing and position coordination of the material ejection and clamping in the material handling device cleverly solves the problem of finished product removal in precision tooling. Through pre-loosening and precise alignment, the consistency of the decorative parts position is ensured, thus ensuring the reliability and efficiency at the end of the production process and forming a complete automated closed loop.

[0035] 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.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] The technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0039] Please see Figure 1 and Figure 2 The pen clip 100 includes a main body 101 and a decorative element 102. The main body 101 has a first groove 1011, a second groove 1012, and a through hole 1013. The decorative element 102 is U-shaped and has a first end 1021 located at the U-shaped opening and a second end 1022 located away from the opening. The first end 1021 is embedded in the first groove 1011, and the second end 1022 is engaged in the second groove 1012. The U-shaped opening of the first end 1021 is bent inward by a distance to form a constricted opening.

[0040] Example 1 Please see Figures 3-6 This embodiment provides a pen clip 100 assembly fixture 2, including a base 24, on which a positioning groove 22, a positioning post 21 and a guide post 23 are provided.

[0041] The base 24 serves as the supporting foundation for the entire pen clip 100 assembly fixture 2, and its structural design plays a crucial role in the stability and precision of the fixture 2. In addition to the existing basic structure, the base 24 can be made of high-strength, low-deformation metal materials, such as aluminum alloy or stainless steel, to ensure that it will not undergo significant deformation due to stress or environmental factors during long-term use, thereby guaranteeing the relative positional accuracy of the positioning groove 22, positioning post 21, and guide post 23. The bottom of the base 24 can be equipped with multiple adjustable support feet, whose height can be adjusted via threads to adapt to the flatness of different work surfaces. During operation, if there is slight unevenness on the work surface, adjusting the support feet can keep the base 24 level, preventing instability of the main body 101 or increased assembly errors due to the base 24 tilting. To facilitate the handling and installation of the fixture 2, the base 24 can also be equipped with handling handles or lifting holes.

[0042] The positioning groove 22 is disposed on the base 24. The shape and dimensional accuracy of the positioning groove 22 are crucial for the positioning of the main body 101. In addition to the existing fixing structure, the inner wall of the positioning groove 22 can be treated with surface treatment processes, such as hard chrome plating or spraying a wear-resistant coating, to improve its wear resistance and corrosion resistance. This can reduce the wear of the inner wall of the positioning groove 22 due to long-term use, thereby ensuring the positioning accuracy of the main body 101 during placement, while also reducing wear on the surface of the main body 101.

[0043] The positioning post 21 is fixed to the base 24 and located within the positioning groove 22. The positioning post 21 includes an integrally formed first post 211 and a second post 212. The first post 211 is used to mate with the through hole 1013 of the main body 101 (see reference). Figure 2 The diameter of the second column 212 is smaller than that of the first column 211 and it is closer to the entrance of the positioning groove 22. The outer end face of the second column 212 (i.e., the end closer to the entrance of the positioning groove) is provided with a guide surface 213. The guide surface 213 and the second column 212 form a two-stage guiding structure for guiding the main body 101 before it mates with the first column 211. Although the integrally molded structure of the positioning column 21 has high strength, in some cases, to further improve the accuracy and flexibility of positioning, the first column 211 and the second column 212 can be designed as a detachable connection. For example, the first column 211 can be installed on the second column 212 by threaded connection or snap-fit ​​connection. This allows for the replacement of different specifications of the first column 211 according to the size of the through hole 1013 of different main bodies 101, improving the versatility of the tooling 2. The guide surface 213 on the outer end face of the second column 212 can adopt a more complex curved surface design to achieve more precise guidance. For example, the guide surface 213 can be designed as an involute surface or a hyperbolic surface, so that the main body 101 can enter the positioning area more smoothly before engaging with the first column 211, reducing errors caused by collisions.

[0044] The guide post 23 is fixed to the base 24. The guide post 23 has an upper end face 231 and a lower end face 232. The lower end face 232 faces the positioning post 21, and the upper end face 231 has opposing guide slopes. The angle of the guide slope of the upper end face 231 of the guide post 23 can be optimized according to the material and shape of the decorative part 102. For some decorative parts 102 with softer materials or irregular shapes, the guide slope angle can be appropriately reduced to provide a gentler guiding force and prevent the decorative part 102 from deforming or being damaged during the sliding process. For decorative parts 102 with harder materials and regular shapes, the guide slope angle can be appropriately increased to improve assembly efficiency.

[0045] Please see Figure 3 and Figure 4 The base 24 has a spring hole 221 that connects to the positioning groove 22. An elastic element 26 is installed within the spring hole 221. The elastic element 26 and the guide post 23 are located on opposite sides of the positioning post 21. One end of the elastic element 26 extends into the positioning groove 22 and can exit the positioning groove 22 under external force. The elastic element 26 includes a spring and an abutment. The abutment is connected to the spring and located within the positioning groove 22. The design of the elastic element 26 can be further optimized. The spring constant can be selected according to actual assembly requirements to ensure that the elastic element 26 provides appropriate resistance during the placement of the main body 101, preventing the main body 101 from moving due to external force. The shape of the abutment can be designed as an arc or cone shape that matches the surface of the main body 101 to increase the contact area with the main body 101 and improve positioning stability.

[0046] Please see 5 and Figure 6 The positioning post 21, the inner wall of the positioning groove 22, and the lower end face 232 of the guide post 23 together define a placement space 25 for accommodating the main body 101. When the pen clip 100 is assembled, the main body 101 is placed in the placement space 25, the second end 1022 of the decorative piece 102 is hung in the second groove 1012, and the first end 1021 of the decorative piece 102 is gradually opened and slid into the first groove 1011 by the guide slope (see...). Figure 2 ).

[0047] The guide post 23 has slides 233 on both sides. The slides 233 are connected to the guide slope of the upper end face 231 and the lower end face 232. When the decorative piece 102 slides into the slide 233 along the guide slope, the slide 233 applies a pushing force to the first end 1021 of the decorative piece 102 in a direction away from the second end 1022, ensuring that the second end 1022 is tightly pressed into the second groove 1012, reducing the probability of the second end 1022 dislodging from the second groove 1012. The design of the slides 233 can be more diverse. The width and depth of the slides 233 can also be precisely designed according to the size of the decorative piece 102 to ensure that the decorative piece 102 can slide stably in the slides 233. For example, the distance between the slides 233 on both sides of the guide post 23 gradually decreases from the upper end face 231 downwards, so that the first end 1021 of the decorative piece 102 can smoothly slide into the first groove 1011 along the slide 233 by its own elastic energy. When the main body 101 is placed in the placement space 25, the connection between the slide 233 and the lower end face 232 covers the outer area of ​​the first groove 1011 of the main body 101. That is, the guide post 23 completely presses against and covers the position of the first groove 1011 of the main body 101, so that the first end 1021 of the decorative piece 102 can smoothly enter the first groove 1011 along the slide 233 without being blocked by the outer contour of the main body 101 (see...). Figure 2 ).

[0048] Example 2 See Figure 7 - Figure 12 This embodiment discloses a pen clip 100 assembly device, which includes a rotatable turntable 7. The turntable 7 is equipped with the pen clip 100 assembly fixture 2 described in Embodiment 1. A main body pushing device 3, a decorative part gripping device 5, a pressing device 6, and a material picking device 8 are arranged sequentially around the turntable 7. A placement tray 4 is arranged next to the decorative part gripping device 5. A decorative part 102 is placed in the placement tray 4. The decorative part gripping device 5 grips the decorative part 102 from the placement tray 4 and performs initial assembly with the main body 101 in the fixture 2.

[0049] As the transfer component of the pen clip 100 assembly equipment, the rotational accuracy and stability of turntable 7 directly affect the efficiency and quality of the entire assembly process. To improve the rotational accuracy of turntable 7, a high-precision servo motor can be used to drive it. Servo motors have advantages such as high control precision and fast response speed, ensuring that turntable 7 rotates accurately according to the set angle and speed. The surface of turntable 7 can undergo special treatment, such as hard chrome plating or spraying a wear-resistant coating, to improve its wear resistance and corrosion resistance. Simultaneously, locating pins or locating blocks can be installed at the connection between turntable 7 and tooling 2 to ensure the accurate installation position of tooling 2 on turntable 7, avoiding assembly errors caused by tooling 2 installation deviations. To facilitate equipment maintenance and repair, turntable 7 can be designed as a detachable structure. When the equipment malfunctions or needs upgrading, turntable 7 can be quickly disassembled for inspection and repair of the internal drive and transmission components.

[0050] Please see Figure 6 , Figure 7 and Figure 8 The vibratory feeder 9 transports the main body 101 along the pusher track 31 to the push station in front of the fixture 2 according to the set direction. The pusher cylinder 32 drives the push rod 33 to push the main body 101 into the fixture 2. As the source of transporting the main body 101, the performance of the vibratory feeder 9 plays a key role in the transport stability and directional accuracy of the main body 101. In addition to the existing basic structure, the vibratory feeder 9 can adopt advanced vibration control technology, such as variable frequency speed regulation and intelligent vibration control algorithm, to adjust the vibration frequency and amplitude according to the size and material of the main body 101, ensuring that the main body 101 can be stably transported to the push station along the pusher track 31 according to the set direction. The design of the pusher cylinder 32 and the push rod 33 can be further optimized. The pusher cylinder 32 can be a double-acting cylinder to improve the stability and controllability of the thrust. A buffer device, such as a rubber pad or spring buffer, can be installed at the end of the push rod 33. When the push rod 33 pushes the main body 101 into the tooling 2, the buffer device can reduce the impact force between the main body 101 and the tooling 2, preventing damage to the main body 101 due to collision. Sensors, such as photoelectric sensors or proximity sensors, can be installed on the push track 31 to detect the position and quantity of the main body 101. When the main body 101 reaches the push station, the sensors can promptly send a signal to control the push cylinder 32 to start, realizing the automatic push of the main body 101. The turntable 7 rotates, transporting the tooling 2 containing the main body 101 to the decorative part 102 assembly station.

[0051] At the assembly station of decorative part 102, the decorative part gripping device 5 picks up the decorative part 102 from the placement tray 4 and transfers it to the main body 101 position within the fixture 2. The second end 1022 of the decorative part 102 is hung in the second groove 1012 of the main body 101, while the opening of the first end 1021 slides down along the upper end face 231 of the guide post 23 of the fixture 2 into the slide rail 233, achieving a stable initial assembly state between the decorative part 102 and the main body 101. The gripper 63 of the decorative part gripping device 5 can be designed as a flexible gripper 63. The flexible gripper 63 can automatically adjust the clamping force according to the shape and size of the decorative part 102, avoiding damage to the decorative part 102 due to excessive clamping force or slippage due to insufficient clamping force. The flexible gripper 63 can be made of elastic materials such as silicone or rubber to improve its adaptability and reliability. A visual positioning system can be installed on the moving mechanism of the decorative part gripping device 5. The visual positioning system can capture images of the decorative part 102 and the main body 101 in the tooling 2 through a camera, and then calculate the relative position of the decorative part 102 and the main body 101 through an image processing algorithm. This guides the gripper 63 to accurately hang the decorative part 102 in the second groove 1012 of the main body 101, and slide it along the upper end face 231 of the guide post 23 into the slide rail 233, thus achieving more precise initial assembly.

[0052] Please see Figure 9 - Figure 11 The pressing device 6 includes a pressing rod 64 and two grippers 63.

[0053] The pressing rod 64 moves in a first direction toward or away from the pen clip 100 assembly fixture 2. The motion control of the pressing rod 64 can employ a high-precision linear guide and ball screw pair. The linear guide and ball screw pair have advantages such as high motion accuracy and low friction, ensuring the stability and accuracy of the pressing rod 64 when moving in the first direction. Simultaneously, a pressure sensor can be installed at the end of the pressing rod 64 to monitor the pressure applied by the pressing rod 64 to the decorative part 102 in real time. When the pressure reaches a set value, the control system can automatically stop the movement of the pressing rod 64 to prevent damage to the decorative part 102 or the main body 101 due to excessive pressure.

[0054] Two grippers 63 are connected to the pressure rod 64 and move in a second direction, moving relatively closer or further apart. The motion control of the two grippers 63 can be achieved using independent servo motors. Programming can control the speed and distance at which the two grippers 63 move relatively closer or further apart in the second direction to accommodate the assembly requirements of decorative parts 102 of different sizes. The surfaces of the grippers 63 can undergo special treatments, such as hard chrome plating or spraying a wear-resistant coating, to improve their wear resistance and corrosion resistance.

[0055] The first direction and the second direction are perpendicular to each other. When the main body 101 is placed in the pen clip 100 assembly fixture 2 for assembling the decorative part 102, the pressure rod 64 corresponds to the middle part of the decorative part 102, and the two claws 63 correspond to the first end 1021 of the decorative part 102.

[0056] Please see Figure 12 The material handling device 8 includes a material handling clamp 81 and a top material component 82.

[0057] The material picker 81 is used to remove the assembled pen clip 100 from the pen clip 100 assembly fixture 2. The design of the material picker 81 can be customized according to the shape and size of the pen clip 100. The grippers 63 of the material picker 81 can adopt a V-shaped or arc-shaped design to increase the contact area with the pen clip 100 and improve the stability of gripping. At the same time, the clamping force of the material picker 81 can be adjusted pneumatically or electrically to adapt to the gripping needs of pen clips 100 of different weights. The material picker 81 can clamp any unassembled decorative parts 102 into place with appropriate clamping force to ensure the consistency of the assembly of the decorative parts 102.

[0058] The top-mounted component 82 abuts against the decorative component 102 before the picking clamp 81 picks up the pen clip 100. The design of the top-mounted component 82 can be more intelligent; it can be equipped with a pressure sensor to monitor the pressure between the top-mounted component 82 and the decorative component 102 in real time. When the picking clamp 81 picks up the pen clip 100, the top-mounted component 82 can automatically adjust the top-mounting force based on the feedback signal from the pressure sensor, ensuring that the decorative component 102 is not damaged due to excessive top-mounting force during the picking process. The top-mounted component 82 can also press an improperly assembled decorative component 102 into the correct assembly position, serving as a final guarantee of quality consistency.

[0059] The top material component 82 is aligned with the clamping centerline of the material handling clamp 81. Safety protection devices, such as guardrails or light curtain sensors, can be installed around the material handling device 8 to prevent operators from accidentally entering dangerous areas during equipment operation and to ensure their personal safety.
