Description

Technical Field

[0001] This application relates to the field of injection molding manufacturing, and in particular to a rotary material handling mechanism for the manufacture of micro injection molded parts. Background Technology

[0002] In the development of modern manufacturing, micro-injection molding technology has made significant progress due to its unique advantages. Horizontal injection molding machines are widely used, particularly in fields such as wearable smartwatch molding and infrared-emitting micro-components for electronic products. These fields have extremely high requirements for product precision and production efficiency, as the manufacturing quality and production speed of micro-injection molded parts directly affect the performance and market competitiveness of related products. With continuous technological advancements and increasing market demand, the demand for micro-injection molded parts is growing rapidly. Against this backdrop, improving the efficiency and quality of each stage in the micro-injection molding process has become a core focus for the entire industry. This not only helps improve the production efficiency of enterprises but also promotes the rapid development of related industries and meets consumers' demand for high-quality products. In the production process of horizontal injection molding machines, removing the molded parts from the mold is a crucial step. To achieve this, the industry typically uses a material handling mechanism. Typically, it includes grippers and an integrated transmission device that drives the grippers to move in all directions. This integrated transmission device is a large integrated transmission device composed of X-axis linear modules, Y-axis linear modules and Z-axis linear modules, which enables the grippers to move along the X-axis, Y-axis and vertical directions to complete a series of complex processes such as descending into the mold, taking out the molded product in the mold after the mold is opened, raising the product, transferring it to the collection area where the product is placed, and releasing the grippers to unload the material.

[0003] However, existing material handling mechanisms still have significant shortcomings in practical applications. Firstly, their structural design is inadequate, resulting in a large space requirement. Furthermore, due to the high speed of injection-molded micro-parts, these mechanisms require multi-directional displacement and adjustment to unload the product, significantly increasing downtime and shortening effective processing time, thus reducing unloading efficiency. Secondly, for high-end injection-molded micro-parts, secondary grinding, deburring, and inspection are necessary after injection molding. Existing material handling mechanisms rely on manual collection and transfer of products to the next finishing stage, making them unsuitable for large-scale automated production lines. This not only increases labor costs but also further reduces production efficiency, failing to meet the demands of high-efficiency processing. Summary of the Invention

[0004] In order to enable the material handling mechanism to be applied to multiple processing steps in automated production lines as well as to the processing of single injection molded products, thus flexibly adapting to various application scenarios and improving processing efficiency, this application provides a rotary material handling mechanism for the manufacture of micro injection molded parts.

[0005] This application provides a rotary material handling mechanism for manufacturing micro injection molded parts, including a base, an intermittent rotary table disposed on the base, and at least four clamping mechanisms spaced apart circumferentially along the intermittent rotary table. The intermittent rotary table drives the four clamping mechanisms to rotate intermittently in the horizontal direction for processing. Each clamping mechanism includes a rotating arm, a horizontal guide rail, a vertical guide rail, and a clamping assembly. The rotating arm is rotatably connected to the intermittent rotary table to allow the rotating arm to rotate about its horizontal axis. The horizontal guide rail is horizontally disposed on the rotating arm, and the vertical guide rail is vertically disposed at the output end of the horizontal guide rail. The clamping assembly includes a detachable mounting plate and a gripper disposed on the mounting plate. The mounting plate is rotatably disposed at the output end of the vertical guide rail, and the rotating arm can drive the vertical guide rail to rotate to an inclined state. By adopting the above technical solution, the intermittent rotary table drives four clamping mechanisms to rotate intermittently in the horizontal direction for processing. The rotating arm rotates around the horizontal axis, which can drive the vertical guide rail to rotate to an inclined state. The overall structure is reasonable, which can reduce the space occupied by the mechanism and flexibly adjust the position and angle of the grippers, making it easy to pick up and unload materials. Multiple clamping mechanisms work simultaneously, which greatly improves processing efficiency. It can also reduce the displacement and adjustment of the picking mechanism in multiple directions, shorten the idle time of the processing wheel, and improve the unloading efficiency. The mounting plate is detachable and rotatable, which facilitates the replacement of grippers and allows for further flexible adjustment of the gripper posture. This rotary picking mechanism has an intermittent rotary table and multiple clamping mechanisms. Its structural design is flexible and can be applied to a variety of application scenarios. In the first application scenario where the product is obtained through one-time injection molding, when the rotary table is stationary and the injection molding mechanism is located below all four clamping mechanisms, the rotating arm can rotate around its horizontal axis. The horizontal guide rail is horizontally positioned on the rotating arm, and the vertical guide rail is vertically positioned at the output end of the horizontal guide rail. This structural combination is equivalent to having the functions of a rotating arm, an X-axis guide rail, and a Y-axis guide rail, enabling the grippers to perform a series of actions to remove the molded product and stably transfer it to the collection area. In another scenario involving large-scale production line processing where secondary processing is required after injection molding, the intermittent rotary table can drive the four clamping mechanisms to rotate intermittently in the horizontal direction. After the clamping mechanism clamps the molded product, it can rotate above the conveying mechanism of the production line. Since the mounting plate is rotatably positioned at the output end of the vertical guide rail, driving the mounting plate to rotate at this time can adjust it to a horizontal state, thereby allowing the molded product on the grippers to accurately fall into the positioning slot of the conveying mechanism. This meets the material handling and unloading needs in different scenarios, and multi-station processing can further improve processing efficiency. Preferably, the rotating arm includes a mounting frame and a drive source. The mounting frame has a hollow cavity. The horizontal guide rail and the vertical guide rail are both disposed in the mounting frame. The drive source is fixedly disposed in the intermittent rotary table, and the output end of the drive source is connected to the mounting frame.By adopting the above technical solution, the horizontal and vertical guide rails are set in the hollow cavity of the mounting frame, making the structure of the rotating arm more compact, reducing the overall volume of the material handling mechanism, and avoiding the problem of large space occupation caused by unreasonable structural design. Simultaneously, the drive source is fixedly set on the intermittent rotary table, and its output end is connected to the mounting frame. The drive source can directly drive the mounting frame to rotate, thereby driving the horizontal and vertical guide rails to rotate. This rotation method reduces unnecessary displacement and adjustment, shortens the idle time during processing, increases the effective processing time, and thus improves material unloading efficiency. Preferably, the output end of the vertical guide rail is provided with a hinge seat and a rotary drive component. The mounting plate rotates relative to the vertical guide rail through the hinge seat, and the rotary drive component drives the mounting plate to flip. By adopting the above technical solution, since the output end of the vertical guide rail is provided with a hinge seat and a rotary drive component, the mounting plate rotates relative to the vertical guide rail through the hinge seat, and the rotary drive component can drive the mounting plate to flip. This allows the grippers to flexibly adjust their angle during material handling and unloading, enabling more precise adaptation to micro-molded parts of different shapes and positions. Furthermore, during material handling, the flipping of the mounting plate allows the grippers to approach the molded part at the optimal angle, improving gripping accuracy and stability and reducing damage caused by improper handling. During unloading, the flipping of the mounting plate also ensures the molded part is placed in the appropriate orientation into the collection area or the next processing unit, preventing issues with subsequent processing due to improper placement. Moreover, this flexible angle adjustment reduces the need for complex displacement and adjustment in multiple directions by the material handling mechanism, shortens processing downtime, effectively improves unloading efficiency, and reduces labor costs. It can be directly applied to automated production lines for large-scale production, meeting the demands of high-efficiency processing. Preferably, the horizontal guide rail is disposed within the hollow cavity of the mounting frame. The horizontal guide rail includes a guide rod, a mounting block, and a horizontal drive component. Both ends of the guide rod are connected to the inner wall of the mounting frame. The mounting block is disposed within the mounting frame, and the horizontal drive component is disposed within the mounting block, used to drive the vertical guide rail to move horizontally along the guide rod. By adopting the above technical solution, placing the horizontal guide rail within the hollow cavity of the mounting frame can reduce the overall space occupied by the mechanism. The horizontal guide rail includes a guide rod, a mounting block, and a horizontal drive component. Both ends of the guide rod are connected to the inner wall of the mounting frame. The mounting block is disposed within the mounting frame, and the horizontal drive component is disposed within the mounting block. This structure allows the horizontal drive component to drive the vertical guide rail to move horizontally along the guide rod. In the process of picking up micro-injection molded parts, this horizontal movement method, compared with the displacement and adjustment in multiple directions of existing picking mechanisms, reduces unnecessary actions, shortens the idle time of processing, increases the effective processing time, and improves the material unloading efficiency.Preferably, the mounting block is perpendicular to the guide rod, and both ends of the mounting block are fixedly connected to the inner wall of the mounting frame, dividing the hollow cavity of the mounting frame into two cavities. The horizontal drive component drives the vertical guide rail to move along the guide rod within one of the cavities. By adopting the above technical solution, with the mounting block perpendicular to the guide rod and both ends fixedly connected to the inner wall of the mounting frame, the hollow cavity of the mounting frame can be divided into two cavities. This structural design provides a stable and defined movement space when the horizontal drive component drives the vertical guide rail to move along the guide rod within one of the cavities, avoiding interference during movement. The rational layout of different components optimizes the internal structure of the rotary material handling mechanism, making the overall structure more compact and reducing the space occupied by the mechanism. Preferably, the vertical guide rail includes a mounting base and a sliding plate. The mounting base has a cavity inside, with openings at both its top and bottom communicating with the cavity. The sliding plate is slidably disposed within the cavity of the mounting base and can slid out of both openings. The mounting base is fixedly connected to the output end of the horizontal drive component. The guide rod passes through the mounting base and rotates relative to the mounting base. By adopting the above technical solution, since the mounting base of the vertical guide rail has a cavity inside, and openings at both its top and bottom communicating with the cavity, the sliding plate can slide within the cavity of the mounting base and extend out of both openings. Simultaneously, the mounting base is fixedly connected to the output end of the horizontal drive component, and the guide rod passes through the mounting base and rotates relative to it. This allows the sliding plate to slide smoothly along the guide rod within the mounting base under the drive of the horizontal drive component, achieving stable linear motion. This structural design enhances the motion stability of the vertical guide rail, avoids swaying and offset during movement, and thus improves the accuracy of the gripper in picking up and unloading materials in the vertical direction. Preferably, there are two guide rods, which are arranged in parallel and both pass through the mounting base. By adopting the above technical solution, two parallel guide rods, both penetrating the mounting base, provide more stable support and guidance for the vertical guide rail compared to a single guide rod. The two guide rods balance the forces acting on the vertical guide rail during horizontal movement, reducing its sway and offset. This makes the vertical guide rail move more smoothly and accurately along the guide rods under the action of the horizontal drive component, thereby improving the motion accuracy and stability of the material handling mechanism. This, in turn, enhances the accuracy and efficiency of the micro-injection molded part handling operation, ensuring the smooth progress of the entire handling process and contributing to improved production efficiency and product quality. Preferably, the slide plate surface is provided with a T-slot, and the inner wall of the mounting base extends with a T-shaped protrusion, the T-shaped protrusion forming a sliding fit with the T-slot. By adopting the above technical solution, the slide plate surface is provided with a T-slot, and the inner wall of the mounting base extends with a T-shaped protrusion, the two forming a sliding fit.When the vertical guide rail is working, the cooperation between the T-shaped protrusion and the T-shaped groove guides the sliding of the slide plate, making the slide plate slide more stably in the cavity of the mounting seat and preventing the slide plate from shaking or deviating during sliding. This ensures the stability and accuracy of the gripper's movement in the vertical direction, thereby improving the accuracy and efficiency of the material picking and unloading mechanism, which is beneficial to improving the quality and efficiency of the entire micro-injection molding process. Preferably, the intermittent rotary table includes a rotary disk and a transmission structure. The transmission structure is set on the machine base and drives the rotary disk to rotate intermittently, with each rotation being 90°. By adopting the above technical solution, the transmission structure is set on the machine base and drives the rotary disk to rotate intermittently, with each rotation being 90°, so that the rotary disk can rotate intermittently at a fixed angle. Since at least four clamping mechanisms are distributed at intervals along the circumference of the rotary table, this intermittent rotation mode of the rotary disk can drive the four clamping mechanisms to rotate intermittently in the horizontal direction for multi-station processing. This reduces the idle time of processing, increases the effective processing time, and thus improves the unloading efficiency. Moreover, this structural design is reasonable, reducing the space occupied by the mechanism and making it easier to apply to automated production lines for large-scale production, thus reducing labor costs and further improving production efficiency, meeting the needs of high-efficiency processing. Preferably, there are two grippers, which are vertically arranged on the mounting plate. By adopting the above technical solution, since there are two grippers arranged vertically on the mounting plate, during material handling, the two grippers can simultaneously grasp micro-injection molded parts at different positions, or simultaneously grasp two molded injection molded parts, meeting the needs of high-efficiency processing.

[0006] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotary material handling mechanism drives the clamping mechanism to rotate through an intermittent rotary table. With the help of rotating arms, horizontal guide rails, vertical guide rails and clamping components, it can automatically complete a series of operations such as lowering into the mold, taking out the molded product, raising the product, transferring it to the collection area for product placement and unloading. It realizes automated material handling and unloading, and can be directly applied to multiple processing steps in automated processing production lines. It avoids the need for manual collection of products and transfer to the next finishing process. It can also be applied to the processing of single injection molded products, reducing labor costs and improving production efficiency. 2. The rotating design of the mounting plate not only allows for flexible clamping of injection molded parts, but also corrects the posture of the injection molded parts during transfer, so that the injection molded parts can fall smoothly into the conveying mechanism for transfer to the next processing step.

Detailed Implementation

[0009] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0010] This application provides a rotary material handling mechanism for manufacturing micro-injection molded parts, referring to... Figure 1 The system includes a base 1, an intermittent rotary table 2, and four clamping mechanisms 3. The intermittent rotary table 2 is mounted on the base 1, and the four clamping mechanisms 3 are distributed circumferentially along the intermittent rotary table 2. The four clamping mechanisms 3 are arranged in pairs facing each other on the intermittent rotary table 2. The intermittent rotary table 2 drives the four clamping mechanisms 3 to rotate horizontally at a rhythm of 90° each time. This design allows multiple clamping mechanisms 3 to process synchronously, improving overall work efficiency and reducing waiting time.

[0011] Specifically, in this embodiment, the intermittent rotary table 2 includes a rotating disk and a transmission structure. The transmission structure is located inside the base 1 and at the bottom of the rotating disk. The transmission structure drives the rotating disk to rotate intermittently in the horizontal direction, rotating 90° each time. The transmission structure adopts a conventional Geneva mechanism, which converts continuous rotation into intermittent rotation, thus realizing the intermittent rotation of the rotating disk. Other embodiments may also use a ratchet mechanism or similar transmission structure. The function of the intermittent rotary table 2 rotating 90° is to rotate one of the clamping mechanisms 3 holding the injection molded part 90° to the unloading position of the injection molded part. At this unloading position, the gripper 342 opens, releases the injection molded part, and completes the unloading. After unloading, the clamping mechanism 3 continues to rotate 90° to the station of another injection molding machine 4, where it continues to pick up material for the next unloading operation.

[0012] Reference Figure 1 and Figure 2 Specifically, in this embodiment, each of the four clamping mechanisms 3 includes a rotating arm 31, a horizontal guide rail 32, a vertical guide rail 33, and a clamping assembly 34. The rotating arm 31 includes a mounting frame 311 and a drive source 312. The mounting frame 311 has a hollow cavity 3111, a design that provides mounting space for the horizontal guide rail 32 and the vertical guide rail 33, while reducing the weight of the rotating arm 31 and improving rotational flexibility. The mounting frame 311 is rectangular. The drive source 312 is fixedly mounted on the edge of the intermittent rotary table 2. The output end of the drive source 312 is connected to the mounting frame 311. The drive source 312 is a motor, protected by a cover. The motor's output shaft is connected to the mounting frame 311, driving the mounting frame 311 to rotate around its horizontal axis. In summary, the rotating arm 31 is rotatably connected to the rotary table, allowing it to rotate around its horizontal axis. The rotation of the rotating arm 31 allows the vertical guide rail 33 to rotate to an inclined state, facilitating material handling and unloading operations at different angles.

[0013] The horizontal guide rail 32 is horizontally mounted on the rotating arm 31. The horizontal guide rail 32 includes two guide rods 321, a mounting block 322, and a horizontal drive component 323. The two guide rods 321 are parallel to each other within the hollow cavity 3111 of the mounting frame 311, with both ends connected to the inner wall of the mounting frame 311. The guide rods 321 can be cylindrical metal rods. The mounting block 322 is mounted on the mounting frame 311, with the guide rods 321 passing through it. The mounting block 322 is perpendicular to the guide rods 321, and both ends are fixedly connected to the inner wall of the mounting frame 311. This design divides the hollow cavity 3111 of the mounting frame 311 into two cavities, making the installation of the horizontal guide rail 32 more stable. A horizontal drive component 323 is disposed in the middle of the mounting block 322 and located between the two guide rods 321. The horizontal drive component 323 is located in one of the cavities and is used to drive the vertical guide rail 33 to move horizontally along the guide rod 321 in the other cavity. The horizontal drive component 323 is a cylinder; the extension and retraction of the cylinder drives the vertical guide rail 33 to move on the guide rod 321. In other embodiments, an electric push rod or similar device can also be used as the horizontal drive component 323. The horizontal drive component 323 drives the vertical guide rail 33 to move horizontally along the guide rod 321, bringing the clamping assembly 34 closer to the mold of the injection molding machine 4.

[0014] The vertical guide rail 33 is vertically positioned at the output end of the horizontal guide rail 32. The vertical guide rail 33 includes a mounting base 331, a sliding plate 332, a hinged base 333, and a rotary drive component 334. The mounting base 331 has a cavity with openings at its top and bottom communicating with the cavity. The sliding plate 332 is slidably positioned within the cavity of the mounting base 331 and can slide out through both openings. The sliding plate 332 is driven by a sliding drive component 335, which is a cylinder. The sliding drive component 335 is mounted on the mounting base 331, with its piston rod vertically upwards and fixedly connected to the top of the sliding plate 332, driving the sliding plate 332 to move vertically. This design allows the sliding plate 332 to move flexibly in the vertical direction, meeting the needs of material handling at different heights. Specifically, by providing a T-slot on the surface of the slide plate 332 and extending a T-shaped protrusion on the inner wall of the mounting base 331, the T-shaped protrusion and the T-slot form a sliding engagement. This engagement ensures the stability of the slide plate 332 during movement and prevents it from wobbling or deviating. The piston rod of the horizontal drive component 323 passes through the mounting block 322 and is fixedly connected to the mounting base 331. Both guide rods 321 can penetrate the mounting base 331 and rotate relative to it, further improving the stability of the vertical guide rail 33's movement.

[0015] Specifically, the clamping assembly 34 is disposed on the slide plate 332 and rotates relative to the slide plate 332 via the hinge seat 333. The rotary drive 334 is used to drive the clamping assembly 34 to flip. The rotary drive 334 is a small motor, and the rotation of the motor drives the clamping assembly 34 to flip. In other embodiments, a rotary cylinder or the like can also be used as the rotary drive 334. The slide plate 332 of the vertical guide rail 33 slides downward, causing the clamping assembly 34 to descend to the injection part position inside the mold.

[0016] Specifically, in this embodiment, the clamping assembly 34 includes a detachably mounted mounting plate 341 and grippers 342 disposed on the mounting plate 341. The mounting plate 341 is rotatably mounted on the bottom of the slide plate 332 via a hinge seat 333. The output end of the rotary drive component 334 is fixedly connected to the mounting plate 341. In this embodiment, there are two grippers 342, which are vertically disposed on the mounting plate 341. The grippers 342 are powered by gripper cylinders, and their opening and closing are driven by electricity. Other embodiments may also use pneumatic grippers, which are driven by compressed air. By controlling the grippers 342 to close, the injection molded part is clamped. Then, the slide plate 332 rises via the vertical guide rail 33, the horizontal guide rail 32 drives the vertical guide rail 33 to retract horizontally, and the rotating arm 31 drives the vertical guide rail 33 to rotate to an inclined state.

[0017] In the manufacturing of micro-injection molded parts, there are two typical application scenarios. The working principle of the material handling mechanism in this embodiment in these two scenarios is explained in detail below.

[0018] Reference Figure 2 and Figure 3 Scenario 1: Unloading and feeding of injection molded parts produced in a single injection molding process, wherein the state of the clamping mechanism is as follows (I) Figure 2 As shown.

[0019] Since injection-molded parts require no secondary processing and can be directly unloaded, injection molding machines 4 are installed below each of the four clamping mechanisms 3 in this embodiment. The four clamping mechanisms 3 perform unloading operations simultaneously. Specifically, the intermittent rotary table 2 in this scenario does not rotate. The rotating arms 31, horizontal guide rails 32, and vertical guide rails 33 of the four clamping mechanisms 3 cooperate with each other, allowing the grippers 342 to move and rotate along the X-axis and vertical directions. This completes a series of complex processes, including descending into the mold, removing the molded product from the mold after opening, raising the product, rotating it to an inclined state, driving the vertical guide rail 33 to move closer to the molded product collection area, and then releasing the grippers 342 to achieve stable unloading. The simultaneous processing of the four clamping mechanisms 3 further improves processing efficiency.

[0020] Reference Figure 4 and Figure 5Scenario 2: Material handling and transfer of high-end injection molded parts requiring secondary processing after injection molding, including the state of the clamping mechanism (II). Figure 4 As shown.

[0021] For high-end injection molded parts, secondary grinding, deburring, and inspection are required after injection molding. In this scenario, the material handling process is similar to that of ordinary injection molded parts. Of the four clamping mechanisms 3, one set of opposite clamping mechanisms 3 has an injection molding machine 4 below it, and the other set of opposite clamping mechanisms 3 has a conveying mechanism 5 below it. The conveying mechanism 5 has a positioning structure for placing the molded product according to its shape. In this application scenario, the intermittent rotary table 2 can rotate, rotating 90° each time. When the clamping mechanism 3 above the injection molding machine 4 picks up the injection molded part at the material handling position, the intermittent rotary table 2 rotates, bringing it to the conveying mechanism 5 for unloading and transfer.

[0022] During the transfer process, the rotating arm 31 does not rotate, ensuring that the vertical guide rail 33 remains vertical throughout the rotation. The horizontal guide rail 32 and the vertical guide rail 33 work together to move the injection molded part toward the conveying mechanism 5. Then, the mounting plate 341 is rotated by the rotary drive 334 to adjust the angle of the injection molded part. In this embodiment, the mounting plate 341 is initially vertical, then rotates 90°, so that the two injection molded parts are positioned horizontally directly above the conveying mechanism 5, allowing both injection molded parts to smoothly enter the positioning structure of the conveying mechanism 5. Then, the rotating arm 31, the horizontal guide rail 32, and the vertical guide rail 33 return to their initial state, and the intermittent rotary table 2 continues to rotate, causing the clamping mechanism 3 to return to the material-picking position, ready for the next material picking.

[0023] The implementation principle of this embodiment is as follows: the rotary material handling mechanism drives multiple clamping mechanisms 3 to work sequentially through the intermittent rotary table 2, improving the efficiency of material handling and unloading. The rotating arm 31 can rotate around its horizontal axis, allowing the vertical guide rail 33 to be at different angles, facilitating operation in different positions. The arrangement of the horizontal guide rail 32 and the vertical guide rail 33 allows the clamping assembly 34 to move in both horizontal and vertical directions, meeting the positional requirements for material handling and unloading. The gripper 342 can be angled by flipping the mounting plate 341, better adapting to different material handling and unloading scenarios. The overall structural design is reasonable, reducing space occupation, improving production efficiency, and solving the problems existing in the current material handling mechanism.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
