[0002] In the manufacturing process of medical devices, the dispensing process is crucial, as different medical device products vary greatly in shape, size, and dispensing requirements. Traditional dispensing machine tooling often has a fixed structure, making it difficult to quickly adapt to the dispensing needs of different products. Each time a product is changed for dispensing, a significant amount of time needs to be spent adjusting or reinstalling the tooling, which not only reduces production efficiency but also increases production costs. Moreover, the complex tooling adjustment process is prone to errors, affecting dispensing quality and potentially threatening the quality and safety of medical devices. Utility Model Content

[0003] This invention aims to at least partially solve one of the problems in related technologies. Therefore, one objective of this invention is to provide an automatic dispensing machine for quickly disassembling and replacing tooling trays, meeting the dispensing needs of medical device products of different shapes and sizes, improving the versatility and production efficiency of the dispensing machine, and reducing production costs.

[0004] An automatic dispensing machine includes a worktable, a first motion mechanism, a second motion mechanism, a dispensing mechanism, and a carrier platform. The first motion mechanism is disposed on the worktable, and the carrier platform is movably disposed on the first motion mechanism. Support plates are provided on both sides of the worktable. The second motion mechanism slides on the support plates, and the dispensing mechanism is mounted on the second motion mechanism. The carrier platform comprises:

[0005] Tooling pallet, wherein mounting grooves are provided on both opposite sides of the tooling pallet;

[0006] The installation platform is movably mounted on the first motion mechanism, and the side of the installation platform is provided with a plurality of positioning slots, the positions of which correspond to the positions of the installation slots.

[0007] A plurality of fastening components are provided, one of which is disposed in a positioning groove. The plurality of fastening components surround and form a positioning space. The fastening component includes a clamping member and an elastic member. One end of the elastic member is fixedly connected to the groove wall of the positioning groove, and the other end is connected to the clamping member. When the tooling pallet is placed in the positioning space, the clamping member is inserted into the mounting groove.

[0008] Furthermore, the tooling pallet has four mounting slots, two of which are located on one side of the tooling pallet and the other two on the other side of the tooling pallet. The side of the mounting platform has four positioning slots. The fastening components are four in number, with one fastening component located in one of the positioning slots and corresponding to one of the mounting slots.

[0009] Furthermore, the clamping member includes a mounting part and a pressing part connected to each other. The mounting part is disposed in the positioning groove, and the pressing part is disposed outside the positioning groove and is located on the same horizontal plane as the mounting groove. The elastic member is connected to the mounting part.

[0010] Furthermore, the fastening assembly also includes a guide member connected to the wall of the positioning groove, and the elastic member is sleeved on the guide member.

[0011] Furthermore, the surface of the pressing part facing the mounting groove is arc-shaped, and the bottom of the mounting groove is arc-shaped.

[0012] Furthermore, a limiting block is protruding from one side of the pressing part facing the mounting groove, and a limiting groove is recessed at the bottom of the mounting groove. When the pressing member is inserted into the mounting groove, the limiting block is inserted into the limiting groove.

[0013] Furthermore, the clamping member also includes an auxiliary gripping part, which is connected to the side surface of the mounting part opposite to the pressing part, and the auxiliary gripping part extends horizontally.

[0014] Furthermore, the auxiliary gripping part has anti-slip textures on both sides of its vertical direction.

[0015] Furthermore, the tooling tray has a plurality of positioning pins on one side surface facing the installation platform, and the plurality of positioning pins are spaced apart. The installation platform has a plurality of positioning holes, and the plurality of positioning holes are spaced apart. When the tooling tray is placed in the positioning space, one positioning pin is inserted into one of the positioning holes.

[0016] Furthermore, the end of the locating pin is hemispherical.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] This application's mounting platform comprises two parts: a tooling tray and an installation platform. The tooling tray is used to support medical device workpieces of different shapes and sizes. The installation platform has positioning grooves on its sides for installing fastening components, including clamping elements and elastic elements. Correspondingly, the tooling tray has installation grooves on its sides. When the tooling tray needs to be installed, the operator simply pulls the clamping element outward from the positioning groove. The clamping element moves outward and stretches the elastic element, creating a positioning space on the installation platform. The tooling tray is placed within this positioning space. After releasing the clamping element, the elastic force of the elastic element pushes the clamping element into the installation groove on the side of the tooling tray, thus achieving stable clamping of the tooling tray. When the tooling tray needs to be replaced, the clamping element is pulled out again, disengaging it from the installation groove, allowing the tooling tray to be easily removed and replaced with a tray suitable for other medical device products.

[0019] The tooling mechanism of this application adopts a modular design, significantly improving the efficiency of tooling tray replacement through standardized interfaces (i.e., the mating structure between the mounting platform and the tooling tray) and simple installation methods (using clamping and elastic components). During medical device manufacturing, operators can replace the tooling tray quickly and efficiently by simply pulling the clamping components, eliminating the need for complex tools and cumbersome adjustment steps, greatly reducing equipment changeover time. Furthermore, various specialized tooling trays are designed for medical device products of different shapes and sizes, such as round and square workpiece tooling trays, enabling the dispensing machine to adapt to diverse production needs and improving equipment versatility and production flexibility. In addition, this stable clamping structure ensures that the tooling tray does not shift during dispensing, guaranteeing dispensing quality and contributing to improved production quality and safety of medical devices.

Therefore, they should not be construed as limitations on this invention.

[0034] like Figures 1 to 7As shown, the automatic dispensing machine 1 provided in this application includes a worktable 10, a first motion mechanism 20, a second motion mechanism 30, a dispensing mechanism 50, and a platform 60. The first motion mechanism 20 is disposed on the worktable 10, and the platform 60 is movably disposed on the first motion mechanism 20. Support plates are provided on both sides of the worktable 10. The second motion mechanism 30 is slidably mounted on and connected to the support plates. The dispensing mechanism 50 is installed on the second motion mechanism 30. The platform 60 includes:

[0035] Tooling pallet 61, with mounting grooves 611 provided on both opposite sides;

[0036] The mounting platform 63 has several positioning slots 631 on its side, and the positions of the positioning slots 631 correspond to the positions of the mounting slots 611.

[0037] A plurality of fastening components 65 are provided, one fastening component 65 is disposed in a positioning groove 631, and the plurality of fastening components 65 surround to form a positioning space. The fastening component 65 includes a clamping member 651 and an elastic member 653. One end of the elastic member 653 is fixedly connected to the groove wall of the positioning groove 631, and the other end is connected to the clamping member 651. When the tooling tray 61 is placed in the positioning space, the clamping member 651 is inserted into the mounting groove 611.

[0038] The worktable 10 serves as the basic support, and the X, Y, and Z axis motion mechanism 40 enables the dispensing mechanism 50 to move precisely in three-dimensional space, meeting the dispensing needs at different locations. The tooling tray 61 on the platform 60 is used to place the medical device product to be dispensed. The positioning slot 631 and fastening component 65 on the mounting platform 63 cooperate. When the tooling tray 61 is placed in the positioning space, the clamping component 651 is inserted into the mounting slot 611 under the action of the elastic component 653, realizing the rapid installation and fixation of the tooling tray 61, improving the tooling change efficiency and adapting to the dispensing needs of different products.

[0039] The worktable 10 serves as the basic support component of the entire automatic dispensing machine, providing an installation platform 63 for other components. The first motion mechanism 20 is mounted on the worktable 10, supporting the movement of the platform 60 in the first direction. It forms the foundation plane for the entire dispensing machine positioning system, ensuring the stability of all parts of the equipment and guaranteeing smooth operation during dispensing. In this embodiment, the first motion mechanism 20 is an X-axis motion mechanism.

[0040] The first motion mechanism 20 is mounted on the worktable 10, and its main function is to move the stage 60 in the X-axis direction. Through precise control, it can achieve precise horizontal positioning of the stage 60, allowing the workpiece placed on the stage 60 to be accurately aligned with the dispensing position in the X-axis direction, thus ensuring the accuracy of dispensing. This mechanism is key to realizing the horizontal one-dimensional movement of the dispensing machine, and works in conjunction with other axis motion mechanisms to complete the positioning work for dispensing.

[0041] The tooling tray 61 is used to support medical device workpieces of different shapes and sizes. It has mounting grooves 611 on both opposite sides, which are key structures for quickly installing and securing the tooling tray 61 in conjunction with the fastening assembly 65. Through cooperation with the clamping member 651, the tooling tray 61 can be stably placed on the mounting platform 63, facilitating the loading and unloading of different products and meeting diverse production needs.

[0042] Regarding the tooling tray 61, in addition to the conventional flat type, it can also be designed as a special tray with grooves or raised structures to adapt to medical devices of specific shapes, such as curved joint devices. The mounting platform 63 can adopt a modular splicing design, flexibly combining the number and layout of the positioning slots 631 according to the size requirements of different tooling trays 61. The elastic element 653 in the fastening assembly 65 can be made of a variety of elastic materials, such as rubber springs, metal coil springs, etc., to meet different clamping force requirements.

[0043] The tooling pallet 61 is divided into flat universal type, groove adaptable type, and raised positioning type; the installation platform 63 is available in integral type and modular splicing type; the elastic element 653 includes rubber spring, metal coil spring, disc spring, etc.

[0044] The mounting platform 63 has several positioning slots 631 on its side, corresponding to the mounting slots 611 of the tooling tray 61. The positioning slots 631 are used to install the fastening components 65 and are an important component of the entire platform 60 for enabling quick replacement of the tooling tray 61. They provide mounting positions for the fastening components 65, ensuring that the clamping elements 651 and elastic elements 653 can accurately mate with the tooling tray 61, achieving rapid positioning and fixation of the tooling tray 61.

[0045] Each fastening assembly 65 is located within a positioning groove 631 and consists of a clamping element 651 and an elastic element 653. One end of the elastic element 653 is fixed to the groove wall of the positioning groove 631, and the other end is connected to the clamping element 651. When the tooling pallet 61 is placed in the positioning space, the elastic force of the elastic element 653 pushes the clamping element 651 into the mounting groove 611 of the tooling pallet 61, thereby clamping the tooling pallet 61. This structural design enables the quick installation and removal of the tooling pallet 61, improving tooling change efficiency.

[0046] In this embodiment, the first motion mechanism 20 includes a Y-axis motion mechanism and a Z-axis motion mechanism. The Y-axis motion mechanism is fixedly connected to the support plate and is mainly responsible for driving the Z-axis motion mechanism to move in the Y-axis direction. In conjunction with the X-axis motion mechanism 20, it can expand the working range of the dispensing machine on the plane, allowing the dispensing mechanism 50 to move flexibly in the XY plane, realizing dispensing operations at different positions, and improving the working flexibility and adaptability of the dispensing machine.

[0047] The Z-axis motion mechanism is slidably mounted on the Y-axis motion mechanism, and its main function is to drive the dispensing mechanism 50 to move in the Z-axis direction. Through movement in the Z-axis direction, the dispensing mechanism 50 can adjust the distance between itself and the workpiece to meet the dispensing needs of workpieces of different heights, ensuring that the adhesive can be accurately dripped onto the workpiece during the dispensing process, thereby improving the accuracy and quality of dispensing.

[0048] The dispensing mechanism 50 is mounted on the Z-axis motion mechanism 40 and is the core actuator of the automatic dispensing machine. With the coordinated action of the X, Y, and Z-axis motion mechanisms 40, it can move precisely in three-dimensional space, accurately dispensing the adhesive onto the medical device workpiece placed on the stage 60 according to the set program and requirements, thus completing the dispensing operation.

[0049] Furthermore, the tooling pallet 61 has four mounting slots 611, two of which are located on one side of the tooling pallet 61 and the other two on the other side of the tooling pallet 61. The side of the mounting platform 63 has four positioning slots 631. There are four fastening components 65, one of which is located in one positioning slot 631 and corresponds to one mounting slot 611.

[0050] Four mounting slots 611 and four fastening components 65 are symmetrically distributed on both sides of the tooling tray 61, providing a more balanced clamping force and ensuring greater stability of the tooling tray 61 during dispensing, preventing displacement. At the same time, this standardized quantity setting facilitates the design of uniformly sized tooling trays 61 and mounting platforms 63 for different products, improving the versatility of the dispensing machine and reducing production and maintenance costs.

[0051] For the layout of the tooling tray 61 mounting slot 611 and fastening assembly 65, in addition to a symmetrical distribution, an asymmetrical layout that is more conducive to stable support can be adopted according to the center of gravity or stress characteristics of the medical device product. In terms of quantity, a certain amount of expansion space can be reserved to facilitate the addition of fastening assemblies 65 as needed in the future to accommodate workpieces of larger size or special shape.

[0052] Furthermore, the clamping member 651 includes a mounting part 6511 and a pressing part 6513 connected to each other. The mounting part 6511 is located in the positioning groove 631, and the pressing part 6513 is located outside the positioning groove 631 and is located on the same horizontal plane as the mounting groove 611. The elastic member 653 is connected to the mounting part 6511.

[0053] The mounting part 6511, within the positioning groove 631, serves to fix the position of the clamping member 651, ensuring its stable installation on the mounting platform 63. The pressing part 6513 is on the same horizontal plane as the mounting groove 611, facilitating insertion into the mounting groove 611 to achieve the clamping function. The elastic member 653, connected to the mounting part 6511, provides elasticity to the clamping member 651. When the tooling pallet 61 is placed in position, the pressing part 6513, under the action of the elastic member 653, presses firmly against the mounting groove 611 of the tooling pallet 61, ensuring the stability of the tooling pallet 61. This structural design also facilitates operator handling of the clamping member 651.

[0054] The mounting portion 6511 of the clamping member 651 can be designed with different fixing methods such as snap-fit ​​or threaded connection to enhance its stability within the positioning groove 631. In addition to being planar, the shape of the pressing portion 6513 can also be designed with a toothed or corrugated structure to increase the friction with the mounting groove 611 and prevent the tooling tray 61 from sliding.

[0055] Furthermore, the fastening assembly 65 also includes a guide 655, which is connected to the groove wall of the positioning groove 631, and an elastic element 653 is sleeved on the guide 655.

[0056] The guide component 655 ensures a stable movement trajectory for the elastic component 653 during extension and retraction, preventing twisting or displacement of the elastic component 653 under stress and guaranteeing that the clamping component 651 can accurately insert into and disengage from the mounting slot 611. This not only improves the accuracy of installing and removing the tooling tray 61 but also extends the service life of the elastic component 653, ensuring the long-term stable operation of the fastening assembly 65 and thus guaranteeing the stable operation of the dispensing machine.

[0057] The structure of guide component 655 can be varied, such as using cylindrical pins, guide rails, or sliders. For the material of guide component 655, wear-resistant metal materials or self-lubricating engineering plastics can be selected to improve the service life and working performance of guide component 655.

[0058] Guide component 655 has three structural types: cylindrical pin type, guide rail slider type, and guide sleeve type; guide component 655 is made of wear-resistant metal (such as stainless steel, copper alloy) and self-lubricating engineering plastic (such as polytetrafluoroethylene).

[0059] Furthermore, the surface of the pressing part 6513 facing the mounting groove 611 is arc-shaped, and the bottom of the mounting groove 611 is arc-shaped.

[0060] The arc-shaped pressing part 6513 and the bottom design of the mounting groove 611 increase the contact area between them. When clamping the tooling tray 61, the pressure can be distributed more evenly, avoiding situations where the pressure is too high or too low in some areas. This not only improves the fixing stability of the tooling tray 61 and reduces the risk of displacement during the dispensing process, but also reduces wear on the tooling tray 61 and the clamping part 651, extending their service life.

[0061] The arc-shaped design of the pressure-retaining part 6513 and the bottom of the mounting groove 611 can be further optimized, such as by using special curves like elliptical arcs or parabolic arcs, to better fit tooling pallets 61 of different shapes and improve the uniformity of pressure distribution. At the same time, cushioning materials, such as silicone pads, can be added to the arc-shaped surface to reduce wear on the tooling pallet 61.

[0062] Furthermore, a limiting block 6515 protrudes from the side surface of the pressing part 6513 facing the mounting groove 611, and a limiting groove 6111 is recessed at the bottom of the mounting groove 611. When the pressing member 651 is inserted into the mounting groove 611, the limiting block 6515 is inserted into the limiting groove 6111.

[0063] The cooperation between the limiting block 6515 and the limiting groove 6111 further restricts the horizontal and vertical displacement of the tooling tray 61 after the clamping member 651 is inserted into the mounting groove 611. During the dispensing process, the tooling tray 61 may be subjected to vibration or external forces. The limiting structure ensures that the tooling tray 61 always remains in a precise position, improving dispensing accuracy, ensuring the dispensing quality of medical device products, and enhancing the production quality and safety of the products.

[0064] The limiting block 6515 and the limiting groove 6111 can be designed in various shapes, such as T-shaped or dovetail-shaped, to enhance the limiting effect. In addition, magnetic material can be provided on the contact surface of the limiting block 6515 and the limiting groove 6111 to further improve the positioning accuracy and stability of the tooling pallet 61.

[0065] Furthermore, the clamping member 651 also includes an auxiliary gripping part 6517, which is connected to the side surface of the mounting part 6511 opposite to the pressing part 6513, and the auxiliary gripping part 6517 extends in the horizontal direction.

[0066] The auxiliary grip 6517 is designed to allow operators to easily hold the clamping member 651, making it easier to pull the clamping member 651 to detach from or insert into the mounting slot 611 when installing or changing the tooling tray 61. The horizontally extended design is ergonomic, facilitating operator application of force, reducing operational difficulty, and improving the efficiency of tooling tray 61 replacement, further demonstrating the human-centered and practical design of this dispensing machine.

[0067] The auxiliary grip 6517 can be designed in various ergonomic styles, such as curved or pistol grip, for easy handling by the operator. In terms of materials, non-slip and elastic materials such as rubber or silicone can be used to improve operational comfort and reliability.

[0068] Furthermore, the auxiliary grip portion 6517 has anti-slip textures on both sides of its vertical direction.

[0069] The anti-slip texture increases the friction between the operator's hand and the auxiliary grip 6517. When pulling the clamping part 651, even if the hands are sweaty or oily, it can effectively prevent slippage, ensuring that the operator can apply force stably and accurately control the movement of the clamping part 651, improving the reliability of operation, ensuring the smooth change of the tooling tray 61, and thus improving the overall working efficiency of the dispensing machine.

[0070] The anti-slip texture can be varied in style, such as horizontal stripes, vertical stripes, and diamond patterns. Granular or abrasive anti-slip materials can also be added to the anti-slip texture to further increase friction. Furthermore, anti-slip textures of different densities can be applied to different locations on the auxiliary grip section 6517 according to the operator's usage habits. Anti-slip texture styles include horizontal stripes, vertical stripes, diamond patterns, and wavy patterns; anti-slip materials include abrasive particles, rubber particles, and corundum particles.

[0071] Furthermore, the tooling pallet 61 has multiple positioning pins 613 on the side surface facing the installation platform 63, and the multiple positioning pins 613 are spaced apart. The installation platform 63 has multiple positioning holes 633, and the multiple positioning holes 633 are spaced apart. When the tooling pallet 61 is placed in the positioning space, a positioning pin 613 is inserted into a corresponding positioning hole 633.

[0072] The engagement of the positioning pin 613 and the positioning hole 633 allows for quick and accurate positioning of the tooling tray 61 when it is placed on the mounting platform 63. This, combined with the clamping component 651, further enhances the positioning accuracy of the tooling tray 61. During the dispensing process, precise positioning ensures accurate dispensing placement, preventing errors caused by deviations in the tooling tray 61's position, thus guaranteeing the dispensing quality of medical device products and improving product yield.

[0073] The locating pin 613 can be designed as a telescopic or elastic locating pin 613, which can automatically adjust its position when installing the tooling pallet 61, improving the convenience of installation. The inner wall of the locating hole 633 can be provided with threads or elastic bushings to enhance the fitting accuracy and stability between the locating pin 613 and the locating hole 633.

[0074] Furthermore, the end of the locating pin 613 is hemispherical.

[0075] The hemispherical end of the locating pin 613 is easier to insert into the locating hole 633, serving as a guide when installing the tooling tray 61, reducing installation difficulty and improving installation efficiency. Simultaneously, the smoother contact between the hemispherical end and the locating hole 633 reduces wear during insertion and removal, extending the service life of the locating pin 613 and the locating hole 633, ensuring long-term stable operation of the positioning structure, and maintaining the high-precision positioning performance of the dispensing machine.

[0076] The hemispherical end of the locating pin 613 can be treated with different surface treatments, such as chrome plating or nickel plating, to improve its wear resistance and corrosion resistance. In addition, a self-lubricating coating can be added to the hemispherical end to further reduce friction during insertion and removal.

[0077] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
