Description

Technical Field

[0001] This invention relates to the field of ribbon box assembly technology, and more specifically to an automated ribbon box assembly production line. Background Technology

[0002] Ribbon cartridges, a common printing consumable, have an internal structure comprising several precision components, including a base, ribbon roll, printing media roll, torsion spring, rollers, and a cover. The assembly of these components is complex and requires high precision. Currently, ribbon cartridge assembly is mostly done manually or on semi-automatic production lines. Manual transfer and positioning are required between assembly processes, resulting in low production efficiency. Furthermore, the inherent randomness of manual operation can easily lead to poor product consistency and low pass rates.

[0003] Some existing automated assembly lines can only handle the loading and assembly of certain components, failing to automate the entire process from bottom shell loading to finished product unloading. Furthermore, the assembly of printing media rolls and ribbon rolls lacks automation for key processes such as front and back detection of the media roll, automatic end extraction, and automatic ribbon end winding and rewinding, resulting in low assembly pass rates and significant challenges in subsequent debugging. In addition, the posture adjustment and precise assembly of small, precision parts such as torsion springs and rollers are difficult to automate, further limiting the overall efficiency and quality of ribbon cartridge assembly. Therefore, a highly integrated, fully automated ribbon cartridge assembly production line is urgently needed. Summary of the Invention

[0038] Finished product unloading device 900. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] See Figures 1 to 10 This invention provides an automatic ribbon cartridge assembly production line, including a frame 100, on which an assembly rotary line 200 is mounted. The assembly rotary line 200 is equipped with a plurality of fixing fixtures 210. Along the conveying direction of the assembly rotary line 200, the frame 100 is sequentially equipped with a bottom shell feeding device 300, a ribbon assembly device 400, a printing media roll assembly device 500, a torsion spring assembly device 600, a rotary wheel assembly device 700, a cover assembly device 800, and [other components]. The finished product unloading device 900; the bottom shell loading device 300 is used to load the bottom shell onto the fixed fixture 210; the ribbon assembly device 400, the printing media roll assembly device 500, the torsion spring assembly device 600, the rotary wheel assembly device 700, and the cover assembly device 800 sequentially install the ribbon roll, the printing media roll, the torsion spring, the rotary wheel, and the cover onto the bottom shell on the fixed fixture 210; the finished product unloading device 900 is used to detect and unload the ribbon cassette that has been assembled on the fixed fixture 210.

[0041] Specifically, in this invention, the assembly rotary line 200 can be in the form of a circular guide rail line, a turntable, or a chain conveyor line, etc., and its function is to carry the fixed fixture 210 and circulate it between various assembly devices. The fixed fixture 210 is provided with a cavity or positioning structure for precise positioning of the bottom shell. During operation, the bottom shell feeding device 300 first places a bottom shell into the empty fixed fixture 210 that has moved to its station. As the assembly rotary line 200 moves in rhythm, the fixed fixture 210 carrying the bottom shell passes through each subsequent assembly device in sequence, and each device precisely loads the corresponding components into the bottom shell. Finally, a complete ribbon box is assembled on the fixed fixture 210, and after the finished product unloading device 900 checks its appearance or the presence or absence of components, it is removed from the fixed fixture 210. This production line highly integrates the dispersed assembly processes, realizing unmanned and automated assembly of the entire ribbon box process. The bottom shell feeding device 300 can adopt the traditional feeding vibratory plate combined with the robotic arm feeding technology. The finished product unloading device 900 in this invention can be a conventional unloading robotic arm and detection device. It can adopt the technology corresponding to patent CN202210446396.7 - A fully automatic loading and unloading system of robotic arm based on vision detection or CN201720268394.8 - An automatic vision detection device for LCD liquid crystal sheets. The details are not described here.

[0042] See Figures 2 to 4 In one embodiment of the present invention, in order to achieve synchronous and efficient assembly of the ribbon roll and the take-up spool, the ribbon assembly device 400 includes a ribbon roll feeding mechanism 410, a ribbon take-up spool feeding mechanism 420, an integrated transfer robot 430, and a ribbon assembly robot 440, all mounted on the frame 100. A ribbon adjustment platform 450 and a ribbon adjustment mechanism 460 are slidably mounted on the frame 100. The ribbon roll feeding mechanism 410 and the ribbon take-up spool feeding mechanism 420 both synchronously transfer the ribbon roll and the take-up spool to the two adjustment mechanisms of the ribbon adjustment platform 450 via the same synchronous feeding robot 470. At the end, the ribbon adjustment mechanism 460 can cooperate with the ribbon adjustment platform 450 to pull out the end of the ribbon roll and wind it onto the take-up shaft; a positioning transfer platform 480 is slidably arranged on the frame 100 between the ribbon adjustment platform and the ribbon assembly robot 440; the integrated transfer robot 430 can transfer the take-up shaft and ribbon roll that have been wound on the ribbon adjustment platform 450 to the positioning transfer platform 480; the ribbon assembly robot 440 can install the take-up shaft and ribbon roll that have been wound on the positioning transfer platform 480 into the bottom shell of the fixing fixture 210.

[0043] In the above embodiments, both the ribbon roll feeding mechanism 410 and the ribbon take-up shaft feeding mechanism 420 can be conventional vibration feeding structures, such as a combination of a vibrating tray and a linear vibrator. Furthermore, the ribbon roll and the take-up shaft, as two independent components, are synchronously picked up from their respective feeding mechanisms and placed onto the ribbon adjustment platform 450 by the synchronous feeding robot 470. This synchronous transfer method ensures the consistency of rhythm and positional accuracy of the two components during subsequent coordinated actions. In this embodiment, the synchronous feeding robot 470 has two gripping ends, respectively adapted to the ribbon roll feeding mechanism 410 and the ribbon take-up shaft feeding mechanism 420. On the ribbon adjustment platform 450, the ribbon adjustment mechanism 460 performs a series of actions such as tapping, pulling, and winding to fix the lead-out end of the new ribbon roll onto the take-up shaft or to be wound around the take-up shaft, forming an assembly composed of the ribbon roll and the take-up shaft. Finally, the integrated transfer robot 430 transfers the entire component to the positioning transfer platform 480 for secondary positioning, and then the ribbon assembly robot 440 precisely installs it into the bottom shell. In the above embodiment, the positioning transfer platform 480 is a sliding table structure, equipped with several structures for fixing the take-up shaft, the ribbon roll, and the extended portion of the ribbon roll, such as positioning posts and limiting grooves. Both the integrated transfer robot 430 and the ribbon assembly robot 440 are conventional robots, and will not be described in detail here.

[0044] Based on the above embodiments, see Figure 3 and Figure 4 To securely fix the ribbon roll and take-up shaft on the adjustment platform 450 and drive their coordinated operation, the ribbon adjustment platform 450 includes a mounting frame 451 and two ribbon adjustment motors 452 rotatably mounted on the mounting frame 451. A ribbon sliding assembly 490 is provided on the frame 100, and the mounting frame 451 is mounted on the ribbon sliding assembly 490. Each of the two ribbon adjustment motors 452 has an opening / closing cylinder 453 mounted on its rotating end, and each of the two opening / closing cylinders 453 has a pair of opening / closing support rods 454 on its opening / closing end. The synchronous feeding robot 470 transfers... The take-up spool and the carbon ribbon can be respectively mounted on the same pair of opening rods 454 corresponding to the two opening and closing cylinders 453. The two pairs of opening rods 454 can respectively open and fix the take-up spool and the carbon ribbon. The sliding end of the carbon ribbon sliding assembly 490 or the mounting bracket 451 is provided with two sets of pressing assemblies 455 respectively adapted to the two pairs of opening rods 454. The pressing end of the pressing assembly 455 can extend and retract. The adjusting end of the carbon ribbon adjusting mechanism 460 can cooperate with one pair of opening rods 454 to pull out the end of the carbon ribbon on it and wind it onto the take-up spool on the other pair of opening rods 454.

[0045] In this embodiment, the carbon ribbon sliding assembly 490 can be a conventional sliding module or a cylinder-driven sliding table structure. The same pair of expansion rods 454 form a single columnar structure when retracted. When the carbon ribbon roll and take-up shaft are fitted onto the retracted expansion rods 454, the opening / closing cylinder 453 drives the expansion rods 454 to open, tightening and fixing them from the inner hole. This method is suitable for cores with different apertures, providing reliable fixation without damaging the product. The pressure end of the pressure assembly 455 extends out, restricting the carbon ribbon roll or take-up shaft from the top to prevent axial movement during high-speed rotation or pulling, ensuring winding quality. The pressure assembly 455 is actually a structure combining a cylinder and a limiting block; the cylinder drives the limiting block to seal the top of the expansion rods 454. The two carbon ribbon adjusting motors 452 can rotate independently or in coordination, working with the carbon ribbon adjusting mechanism 460 to complete actions such as tapping, unwinding, and rewinding, achieving a high degree of automation.

[0046] Furthermore, for precise extraction and guidance of the carbon ribbon, see [link to relevant documentation]. Figure 4The ribbon adjustment mechanism 460 includes a ribbon adjustment frame 461 and a ribbon sliding seat 462. A ribbon sliding assembly 490 is disposed on the frame 100. The ribbon adjustment frame 461 is mounted on the sliding end of the ribbon sliding assembly 490. The ribbon sliding seat 462 is slidably mounted on the sliding end of the ribbon sliding assembly 490. The sliding direction of the ribbon sliding seat 462 is parallel to the line connecting the two adjustment ends of the ribbon adjustment platform 450. An adjustment driver 463 is disposed on the ribbon adjustment frame 461 for driving the ribbon sliding seat 462 to slide. A ribbon extension is disposed on the ribbon sliding seat 462. The carbon ribbon telescopic cylinder 464 has a base 465 on its telescopic end. A carbon ribbon peeling block 466 and a carbon ribbon clamping block 467 are slidably disposed on the base 465. Two opening and closing actuators 468 are provided on the base 465 to drive the carbon ribbon peeling block 466 and the carbon ribbon clamping block 467 respectively. The two opening and closing actuators 468 can drive the carbon ribbon peeling block 466 and the carbon ribbon clamping block 467 to cooperate with each other to clamp the end of the carbon ribbon roll. The carbon ribbon telescopic cylinder 464 can drive the carbon ribbon peeling block 466 and the carbon ribbon clamping block 467 to move closer to or away from the carbon ribbon adjustment platform 450.

[0047] During operation, the ribbon telescopic cylinder 464 pushes the base 465 towards the newly placed ribbon roll on the ribbon adjusting motor 452. Driven by the corresponding opening / closing driver 468, the ribbon peeling block 466 actuates first, using its cutting edge or friction surface in conjunction with the ribbon adjusting motor 452 to peel off the outermost end of the roll driven by the corresponding spreading rod 454. Then, another opening / closing driver 468 actuates the ribbon clamping block 467, closing it with the ribbon peeling block 466 to clamp the peeled ribbon head. After the ribbon peeling and end clamping actions are completed, the ribbon telescopic cylinder 464 retracts the ribbon clamping block 467 and the ribbon peeling block 466 together, thus pulling out the ribbon. The adjustment driver 463 drives the ribbon slide seat 462 to move laterally, aligning the pulled-out ribbon head with the take-up shaft. The ribbon adjustment motor 452 corresponding to the take-up shaft starts, and works with the ribbon clamp 467 and the ribbon peeling block 466 to wrap the pulled-out ribbon end around the outer wall of the take-up shaft. The whole process is completed by the precise coordination of multiple moving parts, realizing the automatic ribbon feeding and pre-winding.

[0048] See Figures 5 to 7In one embodiment of the present invention, in order to accurately realize the feeding, posture adjustment and tapping operation of the printing media roll, the printing media roll assembly device 500 includes a media roll feeding mechanism 510, a media roll flipping mechanism 520, a vertical vibration feeding rail 530, a receiving mechanism 540, a tapping mechanism 550 and a media roll assembly robot 560, all mounted on the frame 100. The vertical vibration feeding rail 530 can receive the media roll output by the media roll feeding mechanism 510. A first detection device for detecting the front and back of the media roll is provided on one side of the vertical vibration feeding rail 530. The first detection mechanism 570 is electrically connected to the media roll flipping mechanism 520. The receiving mechanism 540 can receive the media roll output by the direct vibration feeding rail 530. The tapping mechanism 550 is used to pull out the end of the media roll on the receiving mechanism 540. The media roll assembly robot 560 can install the media roll with the tapped end on the receiving mechanism 540 into the bottom shell of the fixing fixture 210.

[0049] The media roll feeding mechanism 510 is typically a vibratory feeder, responsible for organizing messy media rolls into a single output row. In one embodiment of the invention, the media roll flipping mechanism 520 includes a flipping motor and a gripper or suction seat disposed on the rotating end of the flipping motor. The gripper grips or the suction seat adsorbs the media roll on the vibratory feed rail 530, and the flipping motor drives it to flip over. The flipped media roll is then placed back onto the vibratory feed rail 530 by the media roll assembly robot 560 for feeding. The first detection mechanism 570 can be a vision camera or fiber optic sensor, used to identify the winding direction of the media roll. When a reversed media roll is detected, the control system of the entire production line controls the media roll flipping mechanism 520 to perform a 180° flip, ensuring that all media rolls entering the next process have a uniform posture. The tapping mechanism 550 peels off and pulls out the outermost end of the tightly wound media roll, separating it from the roll body, providing convenience for subsequent installation.

[0050] Based on the above embodiments, see Figure 6 and Figure 7To ensure the stability and precise positioning of the media roll during the tapping process, the receiving mechanism 540 includes a sliding assembly 541 mounted on the frame 100, a first lifter 542 mounted on the sliding assembly 541, a receiving seat 543 mounted on the lifting end of the first lifter 542, and an unwinding motor 544 mounted on the receiving seat 543. The rotating end of the unwinding motor 544 is connected to a rotating shaft 545, which is rotatably mounted through the receiving seat 543. The sliding assembly 541 can drive the rotating shaft 545 closer to or further away from the output end of the linear vibrating feed rail 530. The output end of the vibrating feed rail 530 is provided with a clearance opening 531 for avoiding the rotating shaft 545. A limiting pressure plate 532 is located above the clearance opening 531 at the output end of the vibrating feed rail 530. The first lifting device 542 can drive the rotating shaft 545, in conjunction with the limiting pressure plate 532, to pass the media roll output by the vibrating feed rail 530 from bottom to top. The unwinding motor 544 can cooperate with the tapping mechanism 550 to pull out the end of the media roll. The media roll assembly robot 560 can install the media roll with the tapped end on the rotating shaft 545 into the bottom shell of the fixing fixture 210. The specific operation process is as follows: When a media roll is conveyed to the clearance opening 531 at the end of the vibrating feed rail 530, the limiting pressure plate 532 restricts its movement from above. At this time, the sliding component 541 drives the receiving seat 543 to move, so that the rotating shaft 545 is directly below the clearance opening 531. The first lifting device 542 rises, driving the rotating shaft 545 to pass through the clearance opening 531 from bottom to top and insert into the center hole of the media roll, lifting the media roll from the vibrating feed rail 530. After the rotating shaft 545 passes through the center hole of the media roll and lifts the media roll away from the vibrating feed rail 530, the sliding component 541 drives the receiving seat 543 and the media roll on it to move out of the vibrating feed rail 530, the first lifting device 542 resets, and the media roll enters the tapping position. This bottom-up material handling method is compact in structure and reliable in operation. Furthermore, the rotating shaft 545 provides a rotation axis for the subsequent unwinding and tapping operation while handling the material, achieving two benefits at once.

[0051] Furthermore, to accurately and efficiently extract the ends of the media roll, see [link to relevant documentation]. Figure 7The tapping mechanism 550 includes a tapping sliding cylinder 551 mounted on the frame 100 and a tapping sliding seat 552 disposed on the sliding end of the tapping sliding cylinder 551. The sliding direction of the tapping sliding cylinder 551 is parallel to the output direction of the linear vibrating feed rail 530. An adjustment sliding module 553 is disposed on the tapping sliding seat 552. The sliding direction of the adjustment sliding module 553 is perpendicular to the sliding direction of the tapping sliding cylinder 551. A shovel head 554 is disposed on the sliding end of the adjustment sliding module 553. An unwinding motor 544 is disposed on the receiving mechanism 540. A rotating shaft 5 is connected to the rotating end of the unwinding motor 544. 45; The shovel head 554 can cooperate with the unwinding motor 544 to shovel up the end of the medium roll on the rotating shaft 545. The sliding end of the adjusting sliding module 553 is provided with a first clamping cylinder 555. The telescopic end of the first clamping cylinder 555 is provided with a clamping block 556. The first clamping cylinder 555 can cooperate with the shovel head 554 to clamp the end of the medium roll through the clamping block 556. The sliding end of the tap sliding seat 552 and / or the adjusting sliding module 553 is provided with an adjusting cylinder 557. The telescopic end of the adjusting cylinder 557 can press the end area of ​​the medium roll that has been pulled out through the top block 558 to force it to deform and bend.

[0052] In the above embodiment, the unwinding motor 544 drives the rotating shaft 545 to slowly rotate the media roll. Simultaneously, the tapping sliding cylinder 551 moves the shovel head 554 along the tangent or near-tangent direction of the media roll, causing the shovel head 554 to wedge into and lift the outermost end of the media roll. During this process, the positioning sliding module 553 fine-tunes the position of the shovel head 554 so that the tip of the shovel head 554 matches the position of the media roll. After the end is lifted, the first clamping cylinder 555 drives the clamping block 556 to close with the shovel head 554, clamping the end of the media roll. Then, the tapping sliding cylinder 551 or the unwinding motor 544 works in tandem to pull out the end of the required length. Finally, the positioning cylinder 557 extends and presses the root of the pulled-out end through the top block 558, causing a crease or plastic deformation, keeping the area in a fixed shape to fit the internal installation space of the bottom shell, facilitating the subsequent gripping and installation by the media roll assembly robot 560.

[0053] See Figure 8In one embodiment of the present invention, in order to precisely adjust the spatial posture of the torsion spring for easy assembly, the torsion spring assembly device 600 includes a torsion spring feeding mechanism 610, a torsion spring flipping mechanism 620, a torsion spring rotary table 630, and a torsion spring assembly robot 640, all mounted on the frame 100. The torsion spring rotary table 630 includes a torsion spring lifting cylinder 631 mounted on the frame 100, a torsion spring mounting seat 632 mounted on the lifting end of the torsion spring lifting cylinder 631, a torsion spring positioning seat 633 rotatably mounted on the torsion spring mounting seat 632, and a torsion spring adjusting motor 634 mounted on the torsion spring mounting seat 632. The rotating end of the torsion spring adjusting motor 634 is connected to one end of the torsion spring positioning seat 633. A retractable extension arm is provided on one side of the torsion spring mounting seat 632. A torsion spring limiting cylinder 635 is retracted, and a torsion spring limiting post 636 is provided on the telescopic end of the torsion spring limiting cylinder 635; the torsion spring assembly robot 640 can transfer the torsion spring output by the torsion spring feeding mechanism 610 to the torsion spring positioning seat 633; ​​the torsion spring adjusting motor 634 drives the torsion spring to rotate through the torsion spring positioning seat 633 to adjust the spatial posture of the torsion spring; the torsion spring limiting cylinder 635 can drive the torsion spring limiting post 636 to restrict the rotation of the torsion spring on the torsion spring positioning seat 633; ​​the torsion spring flipping mechanism 620 can clamp and flip the torsion spring that has completed rotation adjustment on the torsion spring positioning seat 633; ​​the torsion spring assembly robot 640 can transfer the torsion spring clamped on the torsion spring flipping mechanism 620 and install it in the bottom shell of the fixing fixture 210. The angles of the two leads of the torsion spring are usually distinguished. After the torsion spring assembly robot 640 places the torsion spring onto the torsion spring positioning seat 633, the torsion spring adjustment motor 634 drives the torsion spring positioning seat 633 to rotate, while simultaneously using sensors to locate the torsion spring pins or specific structures. When the rotation reaches a preset angle, the torsion spring limiting cylinder 635 drives the torsion spring limiting post 636 to extend and engage with the torsion spring pins, stopping and precisely positioning it. At this point, the torsion spring flipping mechanism 620 clamps the torsion spring, awaiting the torsion spring assembly robot 640 to pick it up. If the orientation of the two ends of the torsion spring does not meet the assembly requirements, the torsion spring flipping mechanism 620 clamps the torsion spring and flips it 180°, finally allowing the torsion spring assembly robot 640 to pick it up and install it. This mechanism can flexibly handle small, elastic parts with uncertain postures, ensuring assembly accuracy.

[0054] In the above embodiments, in order to flip the torsion spring and adjust its direction, the torsion spring flipping mechanism 620 includes a bracket 621, a torsion spring sliding cylinder 622 mounted on the bracket 621, and a torsion spring rotating cylinder 623 mounted on the torsion spring sliding cylinder 622. The bracket 621 is mounted on the frame 100. A torsion spring clamping gripper 624 is provided on the rotating end of the torsion spring rotating cylinder 623. The torsion spring sliding cylinder 622 can drive the torsion spring clamping gripper 624 away from or towards the torsion spring positioning seat 633. The torsion spring clamping gripper 624 can grasp the torsion spring on the torsion spring positioning seat 633.

[0055] See Figure 9 In one embodiment of the present invention, in order to flexibly adapt to the feeding posture of the rotary wheel and adjust it to a uniform installation posture, the rotary wheel assembly device 700 includes a rotary wheel feeding mechanism 710, a rotary wheel clamping mechanism 720, and a rotary wheel assembly robot 730, all mounted on the frame 100. The rotary wheel clamping mechanism 720 includes a frame 721 mounted on the frame 100, a rotary wheel telescopic cylinder 722 disposed on the frame 721, a rotary wheel mounting seat 723 mounted on the telescopic end of the rotary wheel telescopic cylinder 722, and a rotary wheel rotation motor 724 mounted on the rotary wheel mounting seat 723. The extension and retraction direction of the rotary cylinder 722 is parallel to the discharge direction of the rotary feeding mechanism 710. A rotary gripper 725 is installed on the rotating end of the rotary motor 724. The rotary gripper 725 can hold the rotary wheel output by the rotary feeding mechanism 710. A positioning clamping mechanism 740 is provided on the frame 100. The positioning clamping mechanism 740 can clamp and position the fixing fixture 210. The rotary assembly robot 730 can transfer the rotary wheel that has been spatially adjusted on the rotary gripper 725 and install it in the bottom shell of the fixing fixture 210.

[0056] In the above embodiment, the rotary feeding mechanism 710 can be a conventional vibrating tray. The positioning and clamping mechanism 740 includes a pair of opposing clamping cylinders and a cooperating positioning block, respectively installed on both sides of the frame 100 located on the assembly rotary line 200. The rotary gripper 725 clamps a rotary wheel from the discharge port of the rotary feeding mechanism 710. Subsequently, the rotary rotation motor 724 drives the rotary gripper 725 to rotate 90°, aligning the mounting hole of the rotary wheel upwards for easy subsequent assembly. At the same time, the positioning and clamping mechanism 740 clamps or presses the fixing fixture 210 that arrives at the rotary wheel assembly station, eliminating the accumulated errors caused by the conveying of the assembly rotary line 200 and providing a stable reference for the accurate placement of the rotary wheel. This method of adjusting the workpiece orientation first and then positioning the fixture provides double assurance for installation accuracy.

[0057] See Figure 10In one embodiment of the present invention, in order to achieve precise guiding installation and error prevention of the cap, the cap assembly device 800 includes a cap feeding mechanism 810, a stop positioning mechanism 820, a second detection mechanism 830, and a cap assembly robot 840 mounted on the frame 100. The second detection mechanism 830, the stop positioning mechanism 820, and the cap assembly robot 840 are sequentially arranged on one side of the assembly rotary line 200 along the conveying direction of the assembly rotary line 200. The stop positioning mechanism... Mechanism 820 is used to position and support the fixing fixture 210 on the assembly rotary line 200. The frame 100 is positioned above the stopping and positioning mechanism 820 and is provided with a mounting bridge 850. The mounting bridge 850 is provided with a cover limiting hole 851 that is adapted to the fixing fixture 210. The cover assembly robot 840 can grab the cover fed by the cover feeding mechanism 810 and press the cover onto the bottom shell fixed by the fixing fixture 210 by passing the cover through the cover limiting hole 851.

[0058] The cap-loading mechanism 810 can be a conventional vibrating tray. The stopping and positioning mechanism 820 can be a combination of a telescopic cylinder and a positioning seat. The telescopic cylinder lifts the bottom surface of the fixing fixture 210 via the positioning seat, providing support and positioning for precise subsequent installation. The second inspection mechanism 830 can be a vision system used to inspect whether all components inside the bottom shell are installed correctly before cap installation. Only after passing inspection can the cap-assembly robot 840 perform its actions, ensuring quality control. The stopping and positioning mechanism 820 lifts the fixing fixture 210 and precisely positions it directly below the mounting bridge 850. The shape of the cap limiting hole 851 on the mounting bridge 850 precisely matches the outer contour of the cap, and its position is precisely aligned with the bottom shell fastening position on the fixing fixture 210. After the cap-assembly robot 840 grasps the cap, it presses it down vertically, forcing the cap through the cap limiting hole 851. During this process, the cap limiting hole 851 plays a guiding and correcting role, ensuring that the buckle of the cap is accurately aligned with the slot of the bottom shell, preventing product damage caused by misalignment during pressing, and greatly improving the success rate of the cap fastening process and the product yield.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
