[0002] With the continuous development of industry, the functional requirements of injection molded products are becoming increasingly stringent, especially for injection molded parts containing hardware components. These hardware components connect to circuits to achieve multiple functions. However, high positional accuracy is required for the hardware components, necessitating positioning within the mold. To improve positioning accuracy, positioning structures are incorporated into the mold.

[0003] The hardware on the watch frame has a main body and a bent part that bends together. During the watchmaking process, the main body of the hardware needs to be installed on the positioning structure in a certain direction before injection molding.

[0004] Among the relevant technologies, the first method is manual installation. Although it can install the main body of the hardware onto the positioning structure in a certain direction, the efficiency is relatively low. The second method is installation using a robotic arm. However, with a large number of hardware parts located on the table and arranged haphazardly, the robotic arm requires high control and it is difficult to place the main body of the hardware parts onto the positioning mechanism in a specific direction.

The vibration mechanism drives the plate to vibrate, which in turn drives the hardware components on the loading surface to vibrate. During the vibration, the hardware components change shape, and the bent parts of the hardware components enter the clearance part. The bent parts no longer support the main body, so that the main body can be in a ready-to-be-grabbed state. The vibration mechanism stops vibrating, and the gripping device grabs the main body.

[0011] In one optional embodiment, the clearance portion is configured as a clearance hole, and there are multiple clearance holes arranged in an array on the loading surface of the plate.

[0012] In one optional embodiment, the loading surface of the plate is divided into a plurality of second vibration zones, wherein the plurality of clearance holes in any second vibration zone have the same diameter, and the clearance holes in different second vibration zones are set to different diameters.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] With the continuous development of industry, the functional requirements of injection molded products are becoming increasingly stringent, especially for injection molded parts containing hardware components. These hardware components connect to circuits to achieve multiple functions. However, high positional accuracy is required for the hardware components, necessitating positioning within the mold. To improve positioning accuracy, positioning structures are incorporated into the mold.

[0022] The hardware on the watch frame has a main body and a bent part that bends together. During the watchmaking process, the main body of the hardware needs to be installed on the positioning structure in a certain direction before injection molding.

[0023] In related technologies, the first method is manual installation, which, while able to install the main body of the hardware onto the positioning structure in a certain direction, is inefficient. The second method uses a robotic arm, but with a large number of hardware parts scattered on the table in a disorderly arrangement, this requires high control of the robotic arm and makes it difficult to place the main body of the hardware parts onto the positioning mechanism in a specific direction. To solve the above technical problems, this application provides a feeding device that solves or improves the problem of disorderly hardware part arrangement.

[0024] The following is combined Figures 1 to 4 This describes an embodiment of the present application.

[0025] According to an embodiment of this application, a feeding device is provided, including: a vibration mechanism 1 and a plate 2.

[0026] Specifically, the plate 2 is connected to the vibration mechanism 1, which drives the plate 2 to vibrate. The plate 2 is provided with a loading surface, and at least one clearance part 3 is provided on the loading surface. The clearance part 3 is used to accommodate the bent part 401 of the hardware 4 so that the main body 402 of the hardware 4 can be in a gripping state.

[0027] In this embodiment, multiple hardware parts 4 are placed on the loading surface of the plate 2. The vibration mechanism 1 drives the plate 2 to vibrate, which in turn drives the hardware parts 4 on the loading surface to vibrate. During the vibration, the hardware parts 4 change shape. The bent part 401 of the hardware parts 4 falls into the clearance part 3. The bent part 401 no longer supports the main body part 402, so that the main body part 402 can be in a ready-to-grab state. The vibration mechanism 1 stops vibrating, and the gripping device grips the main body part 402.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the hardware part 4 includes a main body 402 and a bending part 401. Both the main body 402 and the bending part 401 are plates. The included angle between the main body 402 and the bending part 401 is 90°. The vibration mechanism 1 drives the plate 2 to vibrate. The bending part 401 of the hardware part 4 falls into the clearance part 3. At the same time, the main body 402 is mounted on the loading surface of the plate 2. The plate surface of the main body 402 is parallel to the plate surface of the plate 2. At this time, the main body 402 is in the form of waiting to be grasped.

[0029] like Figure 2 As shown, the main body 402 is in a grasping state, which facilitates the grasping device to grasp it.

[0030] In one embodiment, such as Figure 2 As shown, the clearance portion 3 is configured as a groove, and there are multiple grooves. The multiple grooves extend along the first direction X and are arranged along the second direction Y. Specifically, the first direction X intersects the second direction Y, and the first direction X is perpendicular to the second direction Y.

[0031] In this embodiment, such as Figure 1As shown, multiple hardware parts 4 are placed on the loading surface of the plate 2. The vibration mechanism 1 drives the plate 2 to vibrate, which in turn drives the hardware parts 4 on the loading surface to vibrate. During the vibration, the hardware parts 4 change shape, and the bent portions 401 of some of the hardware parts 4 fall into the grooves. The main body 402 is mounted on the end of the grooves, so that some of the hardware parts 4 are in a ready-to-be-grabbed state on the loading surface. Multiple grooves extend along the first direction X and are arranged along the second direction Y, which can increase the downward concave area on the loading surface and increase the number of bent portions 401 of the hardware parts 4 falling into the grooves during vibration.

[0032] Specifically, the width of the groove along the second direction Y is less than the width of the main body 402 of the hardware 4, which allows the main body 402 of the hardware 4 to be mounted on the groove opening, so that the main body 402 of the hardware 4 is in a ready-to-grab state. In one embodiment, such as Figure 1 As shown, the sidewalls at both ends of each groove along the first direction X are set as arc-shaped surfaces 301.

[0033] In this embodiment, the arc-shaped surface 301 can reduce the obstruction effect on the bent portion 401 of the hardware 4, making it easier for the bent portion 401 of the hardware 4 at both ends of the groove to fall into the groove, thereby increasing the probability and number of hardware 4 being transformed from a messy state to a graspable state with each vibration.

[0034] In one embodiment, such as Figure 1 As shown, the plate 2 is divided into multiple first vibration zones 5. The multiple grooves in any first vibration zone 5 have the same width along the second direction Y, and the grooves in different first vibration zones 5 are set to have different widths along the second direction Y.

[0035] In this embodiment, such as Figure 1 As shown, multiple first vibration zones 5 are provided on the loading surface of the plate 2. The grooves provided in different first vibration zones 5 have different widths along the second direction Y, which can simultaneously adjust the shape of hardware parts 4 of different sizes so that they are in a ready-to-grab state.

[0036] Multiple first vibration zones 5 are set on the same plate 2, which can expand the applicable range of the feeding device, and can simultaneously adjust the shape of hardware parts 4 of various sizes, thereby improving the feeding efficiency. In one embodiment, the clearance portion 3 is configured as a clearance hole, and multiple clearance holes are arranged in an array on the loading surface of the plate 2.

[0037] In this embodiment, multiple hardware components 4 are placed on the loading surface of the plate 2. The vibration mechanism 1 drives the plate 2 to vibrate, which in turn drives the hardware components 4 on the loading surface to vibrate. During the vibration, the hardware components 4 change shape, and some of the bent portions 401 of the hardware components 4 fall into the clearance holes. The main body 402 is mounted on the end face of the clearance holes, so that some of the hardware components 4 are in a ready-to-be-grabbed state on the loading surface. The multiple clearance holes are arranged in an array on the loading surface of the plate 2, which can increase the downward concave area on the loading surface and increase the number of bent portions 401 of the hardware components 4 falling into the clearance holes during vibration.

[0038] Specifically, the clearance hole is an elongated hole, and the major diameter of the clearance hole is greater than the length of the bent part 401, so that the bent part 401 can pass into the clearance hole.

[0039] Specifically, the clearance hole can also be round, square, or other shapes.

[0040] Specifically, the clearance holes can be arranged in a rectangular array.

[0041] In one embodiment, the loading surface of the plate 2 is divided into multiple second vibration zones, and the multiple clearance holes in any second vibration zone have the same diameter, while the clearance holes in different second vibration zones are set to different diameters.

[0042] In this embodiment, multiple second vibration zones are provided on the loading surface of the plate 2. The diameter of the clearance holes provided in different second vibration zones is different, which can simultaneously adjust the shape of hardware parts 4 of different sizes so that they are in a ready-to-grab state.

[0043] Multiple second vibration zones are set on the same plate 2, which can expand the application range of the feeding device, and can simultaneously adjust the shape of hardware parts 4 of various sizes, thereby improving the feeding efficiency.

[0044] In one embodiment, such as Figure 1 and Figure 3 As shown, the vibration mechanism 1 includes: a housing 101, a cover plate 102, and a vibration assembly.

[0045] Specifically, the top surface of the housing 101 is open; the cover plate 102 is movably connected to the housing 101 corresponding to the open, and the plate 2 is connected to the cover plate 102; the vibration assembly is installed inside the housing 101 and is connected to the cover plate 102 to drive the cover plate 102 to vibrate.

[0046] In this embodiment, such as Figure 1 and Figure 3As shown, the vibration assembly is installed inside the housing 101, which protects the vibration assembly. The vibration assembly is connected to the cover plate 102. The vibration assembly drives the cover plate 102 to vibrate, and the cover plate 102 drives the plate 2 to vibrate, adjusting the shape of the hardware 4 to a gripping position. The cover plate 102 is designed to correspond to the opening of the housing 101, which can prevent dust from entering the vibration assembly.

[0047] Specifically, the cover plate 102 is connected to the housing 101 via an elastic element, allowing relative displacement between the cover plate 102 and the housing 101. The vibration assembly drives the cover plate 102 to vibrate. The elastic element can be a spring, sheet metal, or elastic rope, or other elastic connecting component.

[0048] In another embodiment, the edge of the cover plate 102 is provided with multiple sliders, and the inner sidewall of the box 101 is provided with multiple sliding grooves corresponding to the multiple sliders. The multiple sliders are slidably connected to the sliding grooves. The sliding direction of the sliders is perpendicular to the plate surface of the plate 2, and the sliding direction of the sliders is the same as the vibration direction of the vibration component.

[0049] Specifically, there is a vibration gap between the cover plate 102 and the inner wall of the housing 101, and the cover plate 102 is connected to the vibration assembly.

[0050] Specifically, the vibration mechanism 1 includes at least one voice coil motor, which is installed inside the housing 101, and the vibrating end of the voice coil motor is connected to the cover plate 102.

[0051] Specifically, the voice coil motor directly drives the cover plate 102 via electromagnetic force, eliminating the need for a transmission mechanism. During operation, it exhibits low inertia and an extremely short response time, down to the millisecond level, enabling high-frequency, high-precision vibration control. The output force of the voice coil motor has a strictly linear relationship with the input current, achieving high-precision motion.

[0052] Specifically, four voice coil motors are set up in a rectangular array. The vibrating ends of the four voice coil motors are connected to the cover plate 102 to drive the plate 2 to vibrate, so that the vibration amplitude of each position of the plate 2 is the same, ensuring that the hardware parts 4 at each part of the plate 2 can be effectively adjusted to the gripping shape.

[0053] Specifically, the bottom plate of the housing 101 extends outward to form a connecting plate 103, which has a first connecting hole 1031 for connecting to the workbench surface.

[0054] Specifically, the connecting plate 103 is connected to the workbench by passing the first connecting member through the first connecting hole 1031, thereby improving the stability of the vibration mechanism 1 during operation and preventing the vibration mechanism 1 from moving the housing 101 during operation. The first connecting member can be a screw or a bolt.

[0055] Specifically, a second connecting hole 201 is provided on the plate 2 for connecting with the cover plate 102.

[0056] Specifically, the plate 2 is connected to the cover plate 102 by passing a second connector through the second connecting hole 201. The second connector can be a screw or a bolt.

[0057] Specifically, the side wall of the enclosure 101 is provided with a wire hole 1012 for passing wires through the enclosure 101, so as to facilitate the electrical connection of copper wires with the voice coil motor and other electrical components.

[0058] Specifically, the inner bottom surface of the housing 101 is provided with a receiving groove 1011 for accommodating components such as circuit boards.

[0059] Specifically, it includes two vibration mechanisms 1, and the cover plates 102 of the two vibration mechanisms 1 are connected to the plate body 2. They can drive the entire plate body 2 to vibrate when the size of the plate body 2 is increased. After the plate body 2 is increased, it can accommodate more hardware parts 4.

[0060] In one embodiment, a fence 6 is also included, which is attached to the cover plate 102 and surrounds the outside of the plate body 2.

[0061] In this embodiment, the fence 6 is provided to prevent the hardware 4 from falling outside the plate 2, and to increase the number of hardware 4 placed on the plate 2, increase the number of hardware 4 that can be adjusted to the gripping position, and improve the efficiency of loading.

[0062] Specifically, in the direction perpendicular to the plate 2, the fence 6 is higher than the plate 2.

[0063] Specifically, the fence 6 includes multiple railings 601 connected end to end, which are connected to the cover plate 102 and surround the outer perimeter of the plate body 2.

[0064] Specifically, the plate 2 is rectangular, and there are four railings 601, which are connected end to end and surround the outer perimeter of the plate 2.

[0065] In one embodiment, it includes: an image recognition device and a robotic arm.

[0066] Specifically, the image recognition device is used to identify the main body 402 of the hardware part 4 in the form to be grasped; the robotic arm is communicatively connected to the image recognition device and is used to grasp the main body 402 of the hardware part 4 in the form to be grasped.

[0067] In this embodiment, the image recognition device includes a camera and an image processor. The camera captures images of the hardware 4 on the vibrating plate 2 and transmits the image information to the image processor. The image processor preprocesses, extracts features, and classifies the image information. The image processor converts the image information into digital information, and through algorithmic processing, deep learning models such as convolutional neural networks (CNNs) can be used to identify the position and category of the object, determine the position of the hardware 4 to be grasped, and form coordinate information.

[0068] The coordinate information of position 4 of the hardware part to be grasped is transmitted to the robotic arm. Based on the coordinate information, the robotic arm plans the path and speed to reach the target point. The path planning takes into account obstacle avoidance and the optimal path.

[0069] The path planning uses inverse kinematics to calculate the angles of each joint in order to reach the target position and grasp the hardware part 4 in the grasping shape.

[0070] Specifically, the robotic arm is equipped with suction cups, which are used to pick up the hardware parts 4 to be grasped.

[0071] Specifically, the suction cup uses a non-contact gripping method, which will not put pressure on the hardware part 4 and damage it; moreover, the suction cup has a simple structure, low maintenance cost, and is suitable for large-scale applications; in addition, the suction cup can quickly adsorb and release, improving production efficiency. At the same time, the suction cup can adapt to objects of different sizes, eliminating the need for frequent fixture changes.

[0072] Secondly, this application also provides a material feeding production line.

[0073] Specifically, the feeding production line includes the feeding device described above.

[0074] It should be noted that the feeding production line includes the feeding device provided in the embodiments of this application, and therefore includes all the advantages of the feeding device mentioned above, so it will not be repeated here.

[0075] The following is an example, combined with Figures 1 to 4 A comprehensive explanation of all the above-mentioned plans is provided.

[0076] Example 1 Four voice coil motors are installed inside the enclosure 101 at the four corners, protecting the motors. The vibrating ends of the voice coil motors are connected to the cover plate 102, driving the cover plate 102 to vibrate. A second connecting hole 201 is provided on the plate 2 for connecting to the cover plate 102. A second connector passes through the second connecting hole 201 to connect the plate 2 to the cover plate 102, causing the cover plate 102 to vibrate.

[0077] A connecting plate 103 extends outward from the bottom plate of the housing 101. The connecting plate 103 is provided with a first connecting hole 1031 for connecting to the workbench. The connecting plate 103 is connected to the workbench by passing a first connector through the first connecting hole 1031, which improves the stability of the vibration mechanism 1 during operation and prevents the vibration mechanism 1 from moving the housing 101 during operation.

[0078] The corner of the cover plate 102 is connected to the housing 101 by multiple springs. There is a vibration gap between the cover plate 102 and the inner wall of the housing 101. The cover plate 102 and the housing 101 can undergo relative displacement. The voice coil motor drives the cover plate 102 to vibrate.

[0079] The voice coil motor directly drives the cover plate 102 via electromagnetic force, eliminating the need for a transmission mechanism. During operation, it exhibits low inertia and an extremely short response time, down to the millisecond level, enabling high-frequency, high-precision vibration control. The output force of the voice coil motor has a strictly linear relationship with the input current, achieving high-precision motion.

[0080] The clearance portion 3 is configured as a groove, with multiple grooves extending along a first direction X and arranged along a second direction Y. Multiple hardware parts 4 are placed on the loading surface of the plate 2. The vibration mechanism 1 drives the plate 2 to vibrate, thereby driving the hardware parts 4 on the loading surface to vibrate. During the vibration, the hardware parts 4 change shape, and some of the bent portions 401 of the hardware parts 4 fall into the grooves. The main body 402 is mounted on the end of the groove, so that some of the hardware parts 4 are in a ready-to-be-grabbed state on the loading surface. The multiple grooves extending along the first direction X and arranged along the second direction Y can increase the downward concave area on the loading surface, thereby increasing the number of bent portions 401 of the hardware parts 4 falling into the grooves during vibration.

[0081] After the plate 2 vibrates for a preset time, the image recognition device takes a picture of the hardware part 4 on the plate 2 and analyzes the image to identify the main body 402 of the hardware part 4 in the grasping state. It generates coordinate information for the main body 402 of the hardware part 4 in the grasping state and transmits the coordinate information to the robotic arm. The suction cup on the grasping end of the robotic arm picks up the main body 402 and installs the main body 402 on the positioning structure in the mold.

[0082] Example 2 Unlike Embodiment 1, the clearance portion 3 is configured as clearance holes. Multiple clearance holes are arranged in an array on the loading surface of the plate 2. Multiple hardware components 4 are placed on the loading surface of the plate 2. The vibration mechanism 1 drives the plate 2 to vibrate, which in turn drives the hardware components 4 on the loading surface to vibrate. During the vibration, the hardware components 4 change shape, and some of the bent portions 401 of the hardware components 4 fall into the clearance holes. The main body 402 is mounted on the end face of the clearance holes, so that some of the hardware components 4 are in a ready-to-be-grabbed state on the loading surface. The array of multiple clearance holes on the loading surface of the plate 2 increases the downward-recessed area on the loading surface, thereby increasing the number of bent portions 401 of the hardware components 4 falling into the clearance holes during vibration.

[0083] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
