Description

Technical Field

[0001] This application relates to the field of urine collection bag manufacturing technology, and more specifically, to an assembly mechanism. Background Technology

[0002] Disposable sterile urine collection bags are pre-assembled, sterilized, and single-use medical consumable kits designed specifically for clinical catheterization procedures. They are widely used in hospitals, clinics, emergency rooms, and home care settings. Their core purpose is to ensure the sterility, convenience, and safety of the catheterization process, reducing the risk of complications such as urinary tract infections.

[0003] In related technologies, the production of disposable sterile urine collection bags usually requires removing the urine bag from the conveyor line, moving it to the assembly position, assembling the bottle onto the urine bag, and then putting the urine bag back onto the conveyor line to continue the subsequent processes. This operation is cumbersome and the assembly efficiency is low. Summary of the Invention

[0004] In order to solve the problems of cumbersome assembly process and low assembly efficiency of urine bags and bottles in related technologies, this application provides an assembly mechanism.

[0005] To achieve the above objectives, this application provides an assembly mechanism for assembling the upper film of a urine bag with the bottle body. The assembly mechanism includes a frame, a transfer assembly, a bottle positioning assembly, and a urine bag positioning assembly. The transfer assembly includes at least one clamping member, which is mounted on the frame and is movable along the length of the frame. The bottle positioning assembly includes a carrier member with a bottle engaging portion for positioning the bottle; the clamping member can move the bottle from the conveyor line to the bottle engaging portion. The urine bag positioning assembly includes a carrier tray, which is mounted on the conveyor line and moved horizontally by the conveyor line; the carrier tray can also move vertically relative to the conveyor line; the carrier tray has a urine bag engaging portion for positioning the urine bag; the clamping member can move the bottle from the bottle engaging portion to the urine bag engaging portion and press it onto the urine bag.

[0006] Furthermore, the urine bag conveyor line is provided with an assembly position, and a pusher is provided at the assembly position. A pusher plate is retractably provided on the side of the pusher facing the carrier. The pusher plate can extend and abut against the carrier, so that the carrier is disengaged from the conveyor line.

[0007] Furthermore, a limiting post is provided on the surface of the push plate facing the carrier plate, and a limiting hole is correspondingly opened on the surface of the carrier plate facing the push plate, and the limiting post can be inserted into the limiting hole.

[0008] Furthermore, at least two of the limiting posts are provided on the push plate, and multiple limiting holes are also provided on the carrier plate, with each limiting hole corresponding to one of the limiting posts.

[0009] Furthermore, a fastener is installed on the frame near the assembly position. The fastener is positioned along the height of the frame on the side of the carrier away from the pusher. The fastener includes a snap-fit ​​connector, which is movably mounted on the fastener along the width of the frame. The snap-fit ​​connector extends from one end toward the urine bag to the urine bag snap-fit ​​portion to snap the urine bag in place.

[0010] Furthermore, a crimping portion is provided on the surface of the urine bag facing the fixing member, and the bottle body is crimped onto the urine bag through the crimping portion. Two snap-fit ​​connectors are symmetrically arranged on both sides of the snap-fit ​​portion of the urine bag along the width direction of the frame, and the two snap-fit ​​connectors respectively abut against both sides of the crimping portion.

[0011] Furthermore, the bottle positioning assembly includes a base, and the carrier is mounted on the base. A first adjusting member is provided between the base and the carrier, and the adjusting member can adjust the relative position of the carrier and the base along the width direction of the frame, so that the carrier and the tray are correspondingly positioned along the length direction of the frame.

[0012] Furthermore, the base includes a fixed plate and a movable plate, with a second adjusting member disposed between the fixed plate and the movable plate. The second adjusting member is capable of adjusting the relative position between the fixed plate and the movable plate along the height direction of the frame. The bearing member is installed on the top of the movable plate.

[0013] Furthermore, the clamping component includes a bottle-body robotic arm and an assembly robotic arm, both of which are slidably mounted on the frame. The bottle-body robotic arm is used to move the bottle from the conveyor line to the bottle-body latching part; the assembly robotic arm is used to move the bottle from the bottle-body latching part to the urine bag latching part and press the bottle onto the urine bag.

[0014] Furthermore, the assembly robotic arm has a retractable working end extending towards one side of the bottle body. The working end is equipped with a suction cup and a protrusion; the suction cup is used to adhere to the bottle body. When the suction cup adheres to the bottle body, the protrusion abuts against the bottle body.

[0015] With the above technical solution, when using the assembly mechanism of this application, the clamping component in the transfer assembly moves the bottle from the conveyor line to the bottle positioning component and places the bottle on the bottle clamping part of the carrier component for positioning. Simultaneously, the conveyor line moves the carrier tray horizontally to a suitable position, then moves vertically, disengaging from the conveyor line. The urine bag is then positioned within the urine bag clamping part on the carrier tray. Afterward, the clamping component moves the positioned bottle to the positioned urine bag and presses the bottle onto the urine bag. After assembly, the carrier tray moves in the opposite direction along the height of the frame, re-engaging with the conveyor line, which then continues to move the carrier tray normally.

[0016] The assembly mechanism provided in this application can directly complete the assembly of the bottle and the upper film of the urine bag on the urine bag conveyor line. There is no need to remove the urine bag from the conveyor line and transfer it to a separate assembly position during the assembly process, and then put it back on the conveyor line after the assembly is completed. This significantly simplifies the operation process, reduces material handling links, and effectively improves assembly efficiency.

[0017] During assembly, the bottle positioning component positions the bottle using the bottle-locking part on its carrier, while the urine bag positioning component positions the urine bag using the urine bag-locking part on the carrier tray, ensuring accurate and reliable positioning of both during assembly. After positioning, the clamping parts of the transfer component precisely transfer and press the bottle onto the urine bag, achieving efficient and stable assembly. The entire process is highly automated and precise, effectively guaranteeing assembly quality and consistency.

[0025] This embodiment provides an assembly mechanism to solve the problems of cumbersome assembly process and low assembly efficiency of urine bags and bottles in related technologies.

[0026] Please see Figure 1 This embodiment provides an assembly mechanism for assembling the upper film of a urine bag with the bottle body. The assembly mechanism includes a frame 100, a transfer assembly 200, a bottle positioning assembly 300, and a urine bag positioning assembly 400. The transfer assembly 200 includes at least one clamping member, which is mounted on the frame 100 and is movable along the length of the frame 100. The bottle positioning assembly 300 includes a carrier 310, which has a bottle engaging portion 311 for positioning the bottle; the clamping member can move the bottle from the conveyor line to the bottle engaging portion 311. The urine bag positioning assembly 400 includes a carrier tray 410, which is mounted on a conveyor line and moves horizontally via the conveyor line. The carrier tray 410 can also move vertically relative to the conveyor line. The carrier tray 410 is provided with a urine bag engaging portion 411 for positioning the urine bag. A clamping member can move the bottle body from the bottle engaging portion 311 to the urine bag engaging portion 411 and press it onto the urine bag.

[0027] Specifically, when using the assembly mechanism of this embodiment, the bottle conveyor line transports the bottle to a position close to the bottle positioning component 300. The clamping member of the transfer component 200 moves the bottle from the conveyor line to the carrier 310 of the bottle positioning component 300 and places it in the bottle snap-fit ​​part 311. The bottle is positioned by the bottle snap-fit ​​part 311 to ensure that the bottle is in the correct assembly posture and spatial coordinates.

[0028] The urine bag conveyor line transports the carrier tray 410 carrying the urine bags horizontally to the assembly position, where the bottle and urine bag are assembled. Once the carrier tray 410 reaches the assembly position, it moves vertically, disengaging from the conveyor line and remaining stably in its current position, unaffected by the conveyor line during assembly. The urine bag locking part 411 on the carrier tray 410 limits and precisely positions the urine bag, ensuring its fixed position and preventing displacement during subsequent assembly.

[0029] After the bottle and urine bag are positioned, the clamping member of the transfer assembly 200 actuates again, picking up the positioned bottle from the bottle engagement part 311 and transferring the bottle to the urine bag located above the urine bag engagement part 411. Subsequently, the clamping member moves the bottle, pressing it into the designated position on the urine bag, completing the assembly of the bottle and urine bag.

[0030] After assembly, the carrier tray 410 moves in the opposite direction along the height of the frame 100, reconnects with the conveyor line, and resumes synchronous operation. At this time, the urine bags with completed bottle assembly continue to enter the next process along the conveyor line with the carrier tray 410, realizing continuous production.

[0031] The assembly mechanism in this embodiment enables the entire process of urine bag positioning, bottle placement and removal, precise alignment, and crimping assembly to be completed in situ on the conveyor line, without the need to remove or transfer the urine bag midway, significantly improving assembly efficiency and simplifying the assembly process. Furthermore, the bottle positioning component 300 and the urine bag positioning component 400 ensure the assembly accuracy and product consistency of the bottle and urine bag.

[0032] In this embodiment, the assembly process can be completed using only a single clamping member. The clamping member first moves the bottle from the conveyor line to the bottle clamping part 311. After the bottle is positioned, it is then moved to the urine bag clamping part 411 and pressed onto the urine bag. Alternatively, depending on the actual needs, two clamping members can be provided. One clamping member moves the bottle from the conveyor line to the bottle clamping part 311, and the other clamping member moves the bottle from the bottle clamping part 311 to the urine bag clamping part 411 and presses the bottle onto the urine bag. By providing two clamping members, the bottle positioning and assembly actions can be performed simultaneously, improving the assembly efficiency of this embodiment.

[0033] In one embodiment, exemplarily, such as Figures 2 to 4As shown, an assembly position is provided on the urine bag conveyor line. A pusher 420 is provided at the assembly position, and a pusher plate 421 is retractably mounted on the side of the pusher 420 facing the carrier tray 410. The pusher plate 421 can extend and abut against the carrier tray 410, thereby disengaging the carrier tray 410 from the conveyor line. Multiple carrier trays 410 are placed sequentially on the urine bag conveyor line. During normal transport, the conveyor line can move the carrier trays 410 horizontally along the conveyor line until the carrier tray 410 is transported to the assembly position. The pusher plate 421 is retractably mounted on the pusher 420 and extends during assembly, abutting against the carrier tray 410 from its bottom. Through the pushing action, it smoothly lifts the carrier tray 410 vertically, disengaging the carrier tray 410 from the conveyor line's transmission structure, such as a chain, belt, or guide rail. This allows the carrier tray 410 to move up and down actively and controllably at the designated position on the conveyor line, i.e., the assembly position, ensuring that the carrier tray 410 is completely free from the dynamic influence of the conveyor line during the assembly of the urine bag, avoiding positioning deviations caused by vibration or slight displacement of the conveyor line, thereby improving assembly accuracy.

[0034] During the crimping process between the bottle and the urine bag, if the carrier plate 410 remains linked to the conveyor line, slight shaking may occur due to the inertia or gaps in the conveyor line, affecting the crimping quality. The push plate 421 lifts and fixes the carrier plate 410, allowing the urine bag to be positioned and assembled on an independent and stable carrier plate 410. This effectively isolates external disturbances and ensures the accuracy and sealing of the connection between the bottle and the urine bag, making it particularly suitable for disposable sterile medical consumables requiring high assembly precision, as described in this embodiment.

[0035] The push plate 421 features a telescopic design, extending to lift the carrier plate 410 when needed and retracting after assembly, releasing the carrier plate 410 to return it to the conveyor line. This action can be synchronized with the movement of the clamping components and bottle positioning processes, facilitating coordinated operation with the PLC system of the entire automated production line and improving the overall automation level and smooth operation of the equipment.

[0036] It is understood that in this embodiment, the conveyor line for the urine bag can be configured as any type of conveyor belt, guide rail, chain, or other conveying structure, as long as it meets the requirements of this embodiment and drives the carrier tray 410 to move horizontally. Of course, the carrier tray 410 can be placed directly on the conveyor line, and after the conveyor line delivers the carrier tray 410 to the assembly position, subsequent operations can proceed directly. The conveyor line can also be equipped with positioning components, snap-fit ​​components, and limiting components that cooperate with the carrier tray 410 to ensure precise positioning of the carrier tray 410 and the conveyor line, enabling the conveyor line to accurately deliver the carrier tray 410 to the assembly position.

[0037] In one embodiment, exemplarily, such as Figures 2 to 4As shown, a limiting post 422 is provided on the surface of the push plate 421 facing the carrier tray 410, and a corresponding limiting hole 412 is provided on the surface of the carrier tray 410 facing the push plate 421. The limiting post 422 can be inserted into the limiting hole 412. When the push plate 421 extends and lifts the carrier tray 410, the limiting post 422 is simultaneously inserted into the limiting hole 412 on the carrier tray 410, forming a mechanical guiding and positioning engagement. This effectively corrects any slight positional deviations that may occur in the carrier tray 410 during transport, ensuring that the carrier tray 410 is always in a preset, precise position when lifted to the assembly position, avoiding misalignment of the bottle and urine bag during assembly due to accumulated errors or inaccurate positioning.

[0038] The insertion and engagement of the limiting post 422 and the limiting hole 412 ensures that the carrier plate 410 forms a stable and rigid connection structure with the push plate 421 after being lifted. During the subsequent clamping process of pressing the bottle body onto the urine bag, even if subjected to vertical or lateral forces, the carrier plate 410 will not shake, shift, or rotate, significantly improving the stability and reliability of the assembly process and ensuring uniform pressing force between the bottle body and the urine bag during assembly.

[0039] Because each lifting action achieves repeated positioning through the cooperation of the limiting post 422 and the limiting hole 412, the spatial posture of each urine bag at the assembly position is highly consistent. This highly repeatable positioning method helps to achieve product quality stability in mass production, reduce the defect rate, and meet the stringent requirements for production consistency in sterile medical consumables.

[0040] For example, please continue reading Figures 2 to 4 At least two limiting posts 422 are provided on the push plate 421, and multiple limiting holes 412 are also provided on the carrier plate 410, with each limiting hole 412 corresponding to a limiting post 422. This combination of at least two limiting posts 422 and limiting holes 412 forms a multi-point positioning structure, effectively constraining the carrier plate 410's freedom of movement in the horizontal plane and preventing rotation or skewness that may occur during single-point positioning. This ensures that the carrier plate 410 maintains a spatial posture completely consistent with the preset work position after being lifted, greatly improving the alignment accuracy during the assembly of the bottle and urine bag.

[0041] Multiple limiting posts 422 are symmetrically or evenly arranged on the push plate 421. When the push plate 421 lifts the carrier plate 410, the multiple limiting posts 422 simultaneously insert into the corresponding limiting holes 412, making the lifting force distribution more uniform and effectively preventing the carrier plate 410 from tilting, jamming, or locally wearing due to uneven force. This not only ensures the stable positioning of the urine bag during assembly but also extends the service life of the carrier plate 410 and the push mechanism.

[0042] In one embodiment, exemplarily, such as Figure 5 , Figure 6As shown, a fastener 430 is installed on the frame 100 near the assembly position. The fastener 430 is positioned along the height direction of the frame 100 on the side of the carrier 410 away from the pusher 420. The fastener 430 includes a snap-fit ​​connector 431, which is movably mounted on the fastener 430 along the width direction of the frame 100. The snap-fit ​​connector 431 extends towards the urine bag to the urine bag snap-fit ​​portion 411 to snap the urine bag in place. While the pusher 420 positions and supports the carrier 410 from the height direction of the frame 100 via the pusher plate 421 and the limiting structure, the snap-fit ​​connector 431 on the fastener 430 extends towards the carrier 410 along the width direction of the frame 100 to laterally snap and fix the urine bag body. By clamping on both sides and positioning in the middle, the urine bag is constrained in multiple directions, effectively limiting its movement in the horizontal or vertical direction and its rotational freedom around the axis, improving the overall stability of the urine bag during assembly, and avoiding displacement or tilting caused by force on one side.

[0043] Furthermore, when the clamping component presses the bottle body onto the upper membrane of the urine bag, a certain amount of vertical pressure and impact force is generated. If the urine bag is only limited by the snap-fit ​​part without additional fixation, slight displacement or deformation may occur, affecting the sealing performance and connection strength. Actively clamping the urine bag through the snap-fit ​​connector 431 can effectively resist the disturbance caused by the pressing force, ensuring a tight and uniform fit between the bottle body and the urine bag, and improving the reliability and airtightness of the connection.

[0044] Furthermore, the snap-fit ​​connector 431 is movably mounted on the fixing member 430 along the width direction of the frame 100, providing a certain degree of adjustment freedom. It can automatically fine-tune its position when in contact with the urine bag, compensating for minor deviations caused by manufacturing tolerances of the carrier tray 410, cumulative transport errors, or thermal expansion and contraction. In this way, the reliability of the snap-fit ​​is ensured, while avoiding structural damage or jamming problems caused by rigid over-positioning.

[0045] For example, please continue reading Figure 5 , Figure 6 The urine bag has a crimping portion on the side facing the fixing member 430, through which the bottle is crimped onto the urine bag. Two clamping connectors 431 are symmetrically arranged on both sides of the urine bag clamping portion 411 along the width direction of the frame 100, and each clamping connector 431 abuts against both sides of the crimping portion. When the clamping member applies a crimping force to the urine bag's crimping portion, if the crimping area lacks effective support, the urine bag material, especially plastic film or flexible top film, may partially collapse, stretch, or shift, leading to poor sealing or an unstable connection. By symmetrically arranging clamping connectors 431 on both sides of the crimping portion and having them abut against both sides of the crimping portion, symmetrical and balanced lateral support force can be provided to the crimping area during the crimping process, effectively resisting deformation caused by the crimping force, ensuring a uniform, tight, and reliable crimped connection between the bottle and the urine bag, and improving sealing performance and structural strength.

[0046] During the operation of an automated production line, equipment operation may generate vibrations or impacts. The two symmetrical snap-fit ​​connectors 431 tightly abut against both sides of the crimping part, fixing the urine bag in the critical area, enhancing local rigidity and overall stability, effectively suppressing the impact of external disturbances on the assembly point being crimped, and ensuring the smooth progress of the crimping process.

[0047] In one embodiment, exemplarily, such as Figure 7 , Figure 8 As shown, the bottle positioning assembly 300 includes a base 320, and a carrier 310 is mounted on the base 320. A first adjusting member 312 is provided between the base 320 and the carrier 310. The adjusting member can adjust the relative position of the carrier 310 and the base 320 along the width direction of the frame 100, so that the carrier 310 and the carrier tray 410 are correspondingly positioned along the length direction of the frame 100. In the automated assembly process of the urine collection bag, the alignment accuracy of the pressing part on the bottle and the urine bag directly affects the reliability and sealing of the connection. By setting the first adjusting member 312, the coordinates of the carrier 310 in the width direction can be finely adjusted to ensure that the pressing part of the urine bag on the bottle and the carrier tray 410 remains corresponding in the length direction. In this embodiment, the adjustable mechanism of the carrier 310 effectively compensates for equipment installation errors, component processing tolerances, or production line layout deviations, ensuring that each pressing operation is in an ideal alignment state and improving assembly quality.

[0048] Different specifications of disposable sterile urine collection bags may have differences in the spatial layout of the bottle and the urine bag. For example, the urine bag carrier tray 410 of some models is wider, or the bottle installation position is offset. By quickly adjusting the position of the carrier 310 through the first adjusting component 312, multiple product models can be adapted without changing the main structure, meeting the flexible production needs of multi-purpose machines, reducing equipment investment costs, and improving production line utilization.

[0049] When the carrier 310 and the carrier plate 410 are precisely aligned in the length direction, the movement trajectory of the clamping component during material handling remains straight and the path is shorter, reducing unnecessary lateral offset or detours. This not only improves the transfer efficiency but also reduces vibration and impact during the movement, making the entire assembly process smoother and more reliable, and helping to extend the service life of mechanical components.

[0050] For example, please continue reading Figure 7 , Figure 8The base 320 includes a fixed plate 321 and a movable plate 322. A second adjusting member 323 is provided between the fixed plate 321 and the movable plate 322, which can adjust the relative position between the fixed plate 321 and the movable plate 322 along the height direction of the frame 100. The carrier member 310 is installed on the top of the movable plate 322. During the assembly of the urine collection bag, the bottle needs to be picked up from the carrier member 310 by the clamping member and transferred to the urine bag pressing part on the carrier tray 410 for pressing. If the height position of the bottle and the urine bag pressing surface are not at the same level or on the mating plane, it may lead to incomplete pressing, uneven pressure, poor sealing, or even damage to components. By setting the second adjusting member 323, the position of the movable plate 322 and the carrier member 310 on it can be flexibly adjusted in the height direction, thereby accurately controlling the assembly reference height of the bottle, ensuring that it accurately corresponds to the pressing part of the urine bag on the carrier tray 410 in the height direction, and improving the docking accuracy and connection reliability.

[0051] In actual production, components such as the conveyor line, carrier tray 410, and lifting mechanism may have manufacturing tolerances, installation deviations, or wear and sinking due to long-term use, causing slight changes in the height of the carrier tray 410 at the assembly position. The second adjusting component 323 can actively compensate for these errors by finely adjusting the height of the movable plate 322, ensuring that the bottle is always at the optimal height for picking up, placing, and pressing, avoiding mechanical interference or assembly failure caused by height differences, and ensuring process stability.

[0052] In one embodiment, exemplarily, such as Figure 1 , Figure 9 As shown, the clamping components include a bottle-holding robotic arm 210 and an assembly robotic arm 220, both of which are slidably mounted on the frame 100. The bottle-holding robotic arm 210 moves the bottle from the conveyor line to the bottle-holding part 311; the assembly robotic arm 220 moves the bottle from the bottle-holding part 311 to the urine bag-holding part 411 and presses the bottle onto the urine bag. By setting two independent robotic arms to perform the bottle-picking, positioning, and transfer pressing tasks respectively, functional decoupling and parallel operation are achieved. While the assembly robotic arm 220 is pressing the bottle onto the urine bag, the bottle-holding robotic arm 210 can simultaneously grab the next bottle from the conveyor line and place it in the bottle-holding part 311 for pre-positioning. Parallel operation significantly shortens the overall cycle time, avoids wasted idle strokes caused by repeated back-and-forth movements of a single arm, and improves the equipment's production cycle time and assembly efficiency.

[0053] The bottle-loading robotic arm 210 focuses on bottle loading and pre-positioning, with its range of motion concentrated between the conveyor line and the bottle positioning component 300. Meanwhile, the assembly robotic arm 220 focuses on the precise positioning and transfer of bottles, with its path concentrated between the bottle positioning component 300 and the carrier plate 410. Each robotic arm has its own specific function and clear path, effectively avoiding path intersections, spatial conflicts, or mechanical interference that might occur with a single robotic arm in complex movements, thus improving operational safety and stability.

[0054] The assembly robotic arm 220 is dedicated to the final crimping process and can be structurally optimized for the crimping action. For example, it can be equipped with high-precision servo control, a pressure feedback system, or a flexible pressure head to ensure the bottle is crimped onto the urine bag crimping section with constant force and a vertical angle, guaranteeing the seal and reliability of the connection. The bottle robotic arm 210, on the other hand, can be designed as a fast-grabbing structure, focusing on high-speed and stable loading. This specialized design ensures optimal performance for both stages.

[0055] For example, please continue reading Figure 9 The assembly robot arm 220 has a working end 221 that extends towards one side of the bottle. The working end 221 is equipped with a suction cup 222 and a protrusion 223. The suction cup 222 is used to adsorb the bottle. The suction cup 222 relies on vacuum negative pressure to adsorb the object; its connection is essentially a flexible surface contact, which can only effectively transmit axial tensile force and a certain amount of shear force, but can hardly transmit torsional or bending moments. When the assembly robot arm 220 applies a pressing force to the bottle, if only the suction cup 222 is in contact, the bottle may rotate, tilt, or partially warp at the moment of force application, leading to uneven pressing, seal failure, or even assembly failure. The protrusion 223, by rigidly abutting against the bottle surface, forms a mechanical point or local support, which can effectively transmit the bending and torsional moments required for pressing, ensuring that the bottle maintains a stable posture during the pressing process.

[0056] During the pressing of the bottle body onto the upper membrane of the urine bag, pressure must be applied evenly in a predetermined direction. The protrusion 223, acting as a rigid contact point, maintains continuous contact with the bottle body after pressing begins, serving as a guide and balancing force, preventing the bottle from tilting or deflecting due to unilateral force or eccentric loading. This ensures that the pressing force is transmitted more evenly and vertically to the pressing interface, guaranteeing connection strength and sealing.
