Description

Technical Field

[0001] This utility model relates to the field of puncture device assembly technology, and in particular to a puncture device assembly device. Background Technology

[0002] As one of the most basic and widely used medical consumables in clinical diagnosis, treatment, and care, the puncture device typically consists of multiple precision plastic and metal components, including a puncture needle, protective sheath, protective cap, and twist cap. The assembly quality of these components directly affects the product's sealing performance, ease of use, and the safety of medical staff and patients. Therefore, its production process, especially the assembly stage, must adhere to high standards, high efficiency, and high consistency.

[0003] In existing technologies, the assembly of puncture devices mainly relies on two technical modes. The first is the traditional manual or semi-manual assembly line. In this mode, different assembly processes (such as installing the protective sleeve, inserting the puncture needle, and pressing the protective cap) are assigned to different workstations on the assembly line. Workers complete their respective single-step operations manually or with the help of simple pneumatic or electric tools. Semi-finished products are transferred between workstations by hand-to-hand or simple conveyor belts. The second is a substation-based automation solution, which uses multiple independent automated unit machines to perform single assembly tasks. For example, an independent feeding machine is responsible for placing the protective sleeve onto a tray, and then the tray is conveyed to another independent pressing device to complete the insertion of the puncture needle. The various unit machines are connected by conveyor belts, robotic arms, or manual transfer.

[0004] However, the aforementioned production models based on substation operations or independent unit machine combinations reveal serious process defects when dealing with the large-scale, high-cycle puncture device assembly demands. The core problem lies in the fragmented and discontinuous nature of the various processes, lacking a unified and integrated transfer and positioning core. When workpieces are transferred between independent workstations, not only is there the risk of cumulative errors due to repeated positioning and clamping, affecting the final assembly accuracy, but more importantly, the flow of materials and the connection between processes generate significant waiting time and idle cycles, severely disrupting the continuity and compactness of the production process, leading to low overall production efficiency. Furthermore, this loose process layout makes the collaborative control of multiple processes exceptionally complex, making it difficult to form an efficient, stable, and coherent automated operation loop, failing to meet the goals of high integration and maximum efficiency pursued in modern medical consumables production. Therefore, a puncture device assembly device is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a puncture device assembly device, aiming to improve the existing substation assembly mode which lacks a unified core for transmission and positioning, resulting in fragmented processes and discontinuous workflows. This is not only due to the cumulative errors caused by repeated positioning, but also to the overall low efficiency caused by the large amount of waiting time, making it difficult to form an efficient and integrated work loop.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a puncture device assembly device, comprising:

The first mounting shell is equipped with a puncture device loading cylinder and a puncture device clamping cylinder. The angle of the first mounting shell is adjusted by an angle-adjusting hydraulic cylinder.

[0016] As a further description of the above technical solution:

[0017] The cap feeding and pressing mechanism includes a support three, a cap feeding vibratory plate mounted on the support three, a cap feeding block connected to the outlet of the cap feeding vibratory plate, and a cap feeding cylinder for pushing out the caps. The cap feeding and pressing mechanism also includes a moving frame and a connecting frame for realizing two-dimensional translation. The moving frame is driven by a transverse moving hydraulic cylinder, and the connecting frame is mounted on the moving frame and driven by a longitudinal moving hydraulic cylinder. The connecting frame is provided with a cap feeding cylinder for gripping and pressing in the caps.

[0018] As a further description of the above technical solution:

[0019] The cap airtightness testing mechanism includes a support four, a drive cylinder mounted on the support four, and an airtightness testing head connected to the output end of the drive cylinder. The drive cylinder drives the airtightness testing head to make sealed contact with the assembled cap for testing.

[0020] As a further description of the above technical solution:

[0021] The twisted cap feeding and tightening mechanism includes a bracket five, a twisted cap feeding vibratory plate, a twisted cap feeding block, and a twisted cap feeding cylinder mounted on the bracket five. The twisted cap feeding and tightening mechanism also includes a mounting shell two. The mounting shell two achieves angle and position adjustment through an angle-adjusting hydraulic cylinder two and an eccentric plate. The twisted cap feeding and tightening mechanism further includes a twisted cap feeding cylinder driven by a transversely moving hydraulic cylinder two and a twisted cap mounting fixture, which are used to complete the gripping, feeding, and tightening operations of the twisted cap.

[0022] As a further description of the above technical solution:

[0023] The finished product discharge mechanism includes a bracket six shared with the twist cap feeding and tightening mechanism, a discharge channel, and a connecting support frame for supporting the discharge channel. The discharge channel is provided with a channel adjusting cylinder for adjusting the channel state.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, a motor-driven turntable on the main body of the equipment rotates intermittently, and multiple positioning fixtures evenly distributed on the turntable serve as a unified clamping and conveying carrier for the workpieces. This organically connects multiple independent functional stations, such as protective sleeve feeding, piercing device assembly, cap pressing, airtightness testing, cap tightening, and finished product unloading. This integrated and automated process design transforms the originally cumbersome manual assembly process, which required multiple people to work together, into a continuous and efficient automated operation process. This greatly improves production efficiency, reduces reliance on manual labor and errors caused by human factors, ensures the consistency and stability of product assembly, and has significant economic benefits.

[0026] 2. In this invention, by equipping the piercing device assembly mechanism and the cap feeding and tightening mechanism with angle-adjusting hydraulic cylinders, and by equipping the cap feeding and pressing mechanism and the cap feeding and tightening mechanism with two-dimensional translational mechanisms driven by horizontal and vertical hydraulic cylinders, the equipment can accurately adapt to piercing device components of different specifications, even those with specific angle requirements. More importantly, the equipment integrates a dedicated cap airtightness detection mechanism, which can perform online quality monitoring of key sealing performance during assembly, promptly detect and reject defective products, thereby effectively ensuring the quality and safety of the final product. This solves the problem of difficult process quality control in traditional assembly methods and improves the overall product qualification rate. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figures 1-4 An embodiment of this utility model provides a puncture device assembly device, comprising: a device body 1; and a protective sleeve feeding mechanism 2, a puncture device upper assembly mechanism 3, a protective cap feeding and pressing mechanism 4, a protective cap airtightness detection mechanism 5, a twist cap feeding and tightening mechanism 6, and a finished product discharge mechanism 7 arranged sequentially along the circumference of the device body 1; the device body 1 is provided with a plurality of positioning fixtures 104 for clamping and transferring workpieces, and the positioning fixtures 104 move sequentially to the work positions of each mechanism under the drive of the device body 1 to complete the automated assembly process of the puncture device.

[0043] Specifically, by arranging multiple functionally independent mechanisms around a core equipment body 1 and using a unified positioning fixture 104 as a transfer carrier, a highly integrated circular automated production line is constructed. This structure allows all assembly processes to be completed on a compact platform, avoiding the problems of multiple workpiece transfers, repetitive positioning, and process connection in traditional station-based production, thus ensuring the continuity and efficiency of the production process.

[0044] Reference Figure 1 and Figure 4 The main body of the equipment 1 includes a support platform 101 that serves as a stable foundation for the whole machine, a motor 102 that serves as the core power source and is installed on the support platform 101, and a turntable 103 that is connected to the output shaft of the motor 102. Multiple positioning fixtures 104 are evenly distributed and fixed on the upper surface of the turntable 103 along the circumferential direction.

[0045] Specifically, this structure is the core transmission system of the equipment. During operation, the motor 102 intermittently drives the turntable 103 to rotate at precise angles, thereby driving all the positioning fixtures 104 on it to move synchronously and stepwise from one station to the next, providing a unified and precise transmission and positioning reference for each mechanism to process and assemble the workpiece at the designated position.

[0046] Reference Figure 1 , Figure 2 and Figure 5The protective sleeve feeding mechanism 2 includes a bracket 204 that provides an installation base, a protective sleeve feeding vibratory feeder 201 for automatically sorting and orienting scattered protective sleeves, a protective sleeve feeding block 202 connected to the discharge port of the protective sleeve feeding vibratory feeder 201 to form a material buffer channel, a protective sleeve pushing cylinder 203 for accurately pushing individual protective sleeves out of the channel of the protective sleeve feeding block 202, and a protective sleeve feeding cylinder 205 for performing the final gripping and placement action to install the protective sleeves onto the positioning fixture 104.

[0047] Specifically, the mechanism achieved automated feeding of the first part. The protective sleeve feeding vibratory plate 201 ensured that the protective sleeve entered the protective sleeve feeding block 202 in the correct posture, the pushing action of the protective sleeve pushing cylinder 203 achieved precise separation of materials, and the protective sleeve feeding cylinder 205 accurately placed the protective sleeve into the empty positioning fixture 104 that arrived at the station with the turntable 103, laying the foundation for subsequent assembly.

[0048] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 The puncture device assembly mechanism 3 includes a support bracket 302, a puncture device feeding vibratory plate 301 for automatic puncture device sorting, a puncture device feeding block 307 connected to the vibratory plate outlet, a puncture device feeding cylinder 306 for pushing out individual puncture devices, and a mounting shell 303 for performing the final assembly action. The mounting shell 303 is equipped with a puncture device loading cylinder 304 for vertical lowering and a puncture device clamping cylinder 305 for clamping in place. The entire mounting shell 303 is connected to the support bracket 302 through an angle adjustment hydraulic cylinder 308 to achieve overall angle adjustment.

[0049] Specifically, this mechanism is responsible for assembling the core component, the piercing device. After the material is prepared by the piercing device feeding vibratory plate 301, piercing device feeding block 307, and piercing device feeding cylinder 306, the piercing device loading cylinder 304 and piercing device clamping cylinder 305 inside the mounting housing 303 work together to precisely insert the piercing device into the positioning fixture 104, which has a protective sleeve, and compact it. The inclusion of the angle-adjusting hydraulic cylinder 308 allows this mechanism to flexibly adapt to piercing device products with specific tilt angle requirements, enhancing the equipment's versatility.

[0050] Reference Figure 1 , Figure 2 and Figure 8The cap feeding and pressing mechanism 4 includes a support bracket 402 for supporting the structure, a cap feeding vibratory feeder 401 for automatic sorting of caps, a cap feeding block 404 connected to the outlet of the vibratory feeder, and a cap feeding cylinder 403 for pushing out individual caps. The cap feeding and pressing mechanism 4 also includes a mechanism for achieving precise positioning in a two-dimensional plane. This mechanism consists of a moving frame 406 driven by a transverse moving hydraulic cylinder 405 and a connecting frame 408 mounted on the moving frame 406 and driven by a longitudinal moving hydraulic cylinder 407. The upper surface of the connecting frame 408 is provided with a cap feeding cylinder 409 for finally gripping and pressing in the caps.

[0051] Specifically, the mechanism uses a moving frame 406 and a connecting frame 408 driven by a horizontal moving hydraulic cylinder 405 and a vertical moving hydraulic cylinder 407 to achieve precise XY axis positioning of the cap feeding cylinder 409 in the horizontal plane, enabling it to accurately grab the cap from the feeding position, move it directly above the workpiece, and press it down vertically to reliably press the cap into the assembled piercing device assembly.

[0052] Reference Figure 1 , Figure 4 and Figure 9 The cap airtightness testing mechanism 5 includes a bracket 501 as the mounting base, a drive cylinder 502 mounted on the bracket 501 as the actuating component, and a dedicated airtightness testing head 503 connected to the output end of the drive cylinder 502. During operation, the drive cylinder 502 drives the airtightness testing head 503 to move downwards, forming a sealed contact with the upper surface of the assembled cap for subsequent airtightness testing.

[0053] Specifically, this mechanism is a key link in ensuring product quality. When the semi-finished product is transferred to this station, the drive cylinder 502 pushes the airtightness testing head 503 to fit tightly against the protective cap. The external airtightness tester pressurizes or evacuates the inside of the product through the airtightness testing head 503 and monitors the pressure changes to determine whether the sealing performance of the protective cap is qualified, thus realizing online quality monitoring.

[0054] Reference Figure 1 , Figure 2 , Figure 10 and Figure 11The twist cap feeding and tightening mechanism 6 includes a bracket 602 serving as the mounting base, a twist cap feeding vibratory plate 601 for automatic sorting of twist caps, a twist cap feeding block 607 serving as the feeding channel, and a twist cap feeding cylinder 606 for ejecting individual twist caps. The mechanism also includes an adjustable mounting shell 603, which achieves combined adjustment of angle and position through an angle-adjusting hydraulic cylinder 604 and an eccentric plate 605. The mechanism further includes a twist cap feeding cylinder 608 driven by a lateral movement hydraulic cylinder 610 for gripping and feeding, and a twist cap mounting fixture 609 for rotating and locking.

[0055] Specifically, this mechanism is responsible for the final installation of the twist cap. Through a combination of angle-adjusting hydraulic cylinder 604 and eccentric plate 605, it can finely adjust the posture of the tightening action. The twist cap loading cylinder 608, driven by the lateral movement hydraulic cylinder 610, and the twist cap mounting fixture 609, after gripping the twist cap, tighten it onto the workpiece. The twist cap mounting fixture 609 typically has a built-in rotary drive, which can complete the locking with a set torque, ensuring the reliability of the connection.

[0056] Reference Figure 1 , Figure 4 and Figure 12 The finished product discharge mechanism 7 includes a bracket 701 shared with the cap feeding and tightening mechanism 6, a discharge channel 703 for guiding the finished product, and a connecting support frame 704 for supporting the discharge channel 703; the discharge channel 703 is provided with a channel adjusting cylinder 702 for changing the channel path according to the test results to achieve sorting of qualified and unqualified products; the mechanism also includes a discharge cylinder 705 for pushing the finished product out of the positioning fixture 104.

[0057] Specifically, this utility model, through the coordinated operation of the aforementioned mechanisms, constructs a fully automated production process from parts loading, multi-step assembly, online testing, and finished product sorting and unloading. Its core lies in utilizing a turntable 103 driven by a motor 102 and its positioning fixture 104 to form a central rotary conveyor system, efficiently integrating various independent processing, assembly, and testing units. When an empty positioning fixture 104 begins its cycle, it sequentially passes through all processes such as protective sleeve loading, piercing device assembly, cap pressing, airtightness testing, and cap tightening. Finally, the finished product unloading mechanism 7 pushes qualified or unqualified products to the designated unloading channel 703, thereby achieving high-speed, high-precision, and high-quality continuous automated production of the piercing device.

[0058] Working principle: When the device is needed, the motor 102 in the main body 1 of the equipment is started first, driving the turntable 103 to rotate in a stepping motion, which drives all the positioning fixtures 104 to move synchronously.

[0059] The assembly process begins. The empty positioning fixture 104 rotates with the turntable 103 to the station of the protective sleeve feeding mechanism 2. The protective sleeve feeding vibratory plate 201 sorts and arranges the protective sleeves and sends them to the protective sleeve feeding block 202. The protective sleeve pushing cylinder 203 pushes out a single protective sleeve, which is then grabbed and precisely installed into the positioning fixture 104 by the protective sleeve feeding cylinder 205.

[0060] Subsequently, the turntable 103 rotates to the next station, and the positioning fixture 104 with the protective sleeve arrives below the piercing device assembly mechanism 3. The piercing device is supplied by its piercing device feeding vibratory plate 301 and feeding block piercing device feeding block 307. The piercing device feeding cylinder 306 pushes it out, and the piercing device loading cylinder 304 and piercing device clamping cylinder 305 inside the mounting shell 303 work together to accurately insert and clamp the piercing device into the protective sleeve to complete the assembly. The entire mounting shell 303 can be adjusted to the required angle by the angle adjustment hydraulic cylinder 308.

[0061] Next, the turntable 103 transfers the semi-finished product to the cap feeding and pressing mechanism 4. The cap is prepared by the cap feeding vibratory plate 401, cap feeding cylinder 403, and cap feeding block 404 in its feeding system. The moving frame 406 and connecting frame 408, driven by the transverse moving hydraulic cylinder 405 and the longitudinal moving hydraulic cylinder 407, precisely position the cap feeding cylinder 409 directly above the workpiece to perform the gripping and pressing action, thus installing the cap into place.

[0062] Afterwards, the workpiece arrives at station 5 of the cap airtightness testing mechanism. Drive cylinder 502 drives the airtightness testing head 503 to descend, forming a sealed connection with the cap and performing an airtightness test. Workpieces that pass the test arrive at station 6 of the cap feeding and tightening mechanism along with turntable 103. After the cap is prepared by the cap feeding vibratory plate 601, cap feeding cylinder 606, and cap feeding block 607 in its feeding system, the cap is gripped by the cap feeding cylinder 608 and cap mounting fixture 609 driven by the second transverse moving hydraulic cylinder 610. The cap is then adjusted in position by the second mounting shell 603, the second angle adjusting hydraulic cylinder 604, and the eccentric plate 605, and finally tightened onto the workpiece.

[0063] Finally, all assembled finished products arrive at the finished product unloading mechanism 7 via turntable 103. The unloading cylinder 705 actuates, pushing the finished products out of the positioning fixture 104 and sliding out of the equipment via the unloading channel 703, completing the entire automated assembly cycle. At the same time, the channel adjusting cylinder 702 can adjust the channel according to the detection results to achieve automatic sorting of qualified and unqualified products.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
