[0003] These nuts are not only numerous in quantity but also diverse in type, and need to be accurately embedded into plastic products during a single injection molding process. Since the mold temperature during the injection molding process is usually as high as about 120 °C, this poses a huge challenge to manual operation.
[0004] Traditionally, the key step of embedding nuts often relies on manual labor. Workers need to use tools to place nuts into the corresponding positions in the mold one by one in a high-temperature environment. However, this method has many drawbacks: First, the work efficiency is low and cannot meet the requirements of large-scale production. Second, working in a high-temperature environment for a long time poses a serious threat to the physical health of workers, and the safety risks such as burns are significantly increased. In addition, due to the limitations of manual operation, it is difficult to ensure the speed and accuracy of placing nuts.

[0024] The reference numerals and names in the figure are as follows:
[0025] Base 1, feeding device body 2, vibrating disk feeding assembly 3, three-axis moving mechanism 4, nut picking fixture 5, fixture positioning bracket 6, nut positioning fixture 7, discharge port 8, X-axis 9, Y-axis 10 and Z-axis 11. Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Please refer to Figure 1 —2. In the embodiment of the present utility model, a fully automatic nut feeding device includes a base 1 and a feeding device body 2 arranged on the base 1. The feeding device body 2 includes multiple key components: a vibrating disk feeding assembly 3, a three-axis moving mechanism 4, a nut picking fixture 5, a fixture positioning bracket 6 and a nut positioning fixture 7.
[0028] First, at least two vibrating disk feeding assemblies 3 are arranged on the base 1. These vibrating disk feeding assemblies 3 convey different types of nuts to their respective discharge ports 8 in an orderly manner by vibrating feeding. Each vibrating disk feeding assembly 3 can be independently controlled and adjusted to adapt to different types and sizes of nuts.
[0029] Second, a nut picking fixture 5 matching the material at the discharge port 8 is arranged on the three-axis moving mechanism 4, and the number of the nut picking fixtures 5 can be 5. These nut picking fixtures 5 can accurately align and clamp the nuts at the discharge port 8 under the drive of the three-axis moving mechanism 4. The moving directions of the three-axis moving mechanism 4 include the X-axis 9, the Y-axis 10 and the Z-axis 11, thus realizing positioning and moving at any position in space.
[0030] To ensure the accuracy and stability of the nut - picking fixture 5, a fixture positioning bracket 6 is also fixedly arranged on the base 1. The nut - positioning fixture 7 that cooperates with the nut - picking fixture 5 is positioned and placed on the base 1 through the fixture positioning bracket 6. In this way, after the nut - picking fixture 5 picks up the nut from the vibrating - bowl feeding assembly 3, it can accurately place it on the nut - positioning fixture 7.
[0031] In this embodiment, the way for the nut - picking fixture 5 to pick up nuts can be one or more of the ways such as magnetic adsorption, negative - pressure adsorption, or limit clamping. These ways can effectively achieve the rapid and accurate grasping of nuts of different types and sizes.
[0032] Meanwhile, the arrangement mode of multiple nut - picking fixtures 5 is the same as the nut arrangement mode required by the nut - positioning fixture 7. In this way, after the fixture is loosened and placed, the required positioning effect can be achieved, facilitating the subsequent injection - molding process.
[0033] In addition, as a further solution, the number of the feeding - device bodies 2 can be two or more, and different numbers and / or models of vibrating - bowl feeding assemblies 3 can be arranged on each feeding - device body 2. This can further improve the flexibility and efficiency of feeding.
[0034] Embodiment 1:
[0035] The core working principle of the full - automatic nut feeding device lies in its highly integrated and automated feeding, grasping, and positioning processes. Through the coordinated work of the vibrating - bowl feeding assembly 3, the three - axis moving mechanism 4, the nut - picking fixture 5, and the nut - positioning fixture 7, the device realizes the precise and efficient processing of different types of nuts.
[0036] During operation, the vibrating - bowl feeding assembly 3 first orderly arranges and conveys the bulk nuts to the discharge port 8 by vibrating feeding. In this process, the vibrator inside the vibrating - bowl feeding assembly 3 generates a directional vibration, causing the nuts to form a specific movement trajectory in the bowl and finally discharging one by one from the discharge port 8 in a preset order and direction.
[0037] Among them, the vibrating - bowl feeding assembly 3 is a commonly used device in the automated feeding system, and its working principle is based on vibrating - feeding technology. The vibrating - bowl feeding assembly 3 mainly consists of a vibrating - bowl body, a vibrator, a chassis, a controller, and other parts.
[0038] The vibrating - bowl body is a disc - shaped container for storing the nuts to be fed. The vibrator is usually installed at the bottom of the vibrating - bowl body, and it generates a directional vibration force, causing the vibrating - bowl body to vibrate slightly in the horizontal and vertical directions. This vibration will make the nuts form a specific movement trajectory in the vibrating - bowl body.
[0039] The interior of the vibrating bowl body is usually designed with a certain slope and grooves, and these structural features can guide the nuts to move in a preset order and direction. When the vibrating bowl body vibrates, the nuts will move one by one along these slopes and grooves to the position of the discharge port 8.
[0040] The chassis is the supporting part of the vibrating bowl body. It is usually connected to the vibrator and transmits the vibration force to the vibrating bowl body. The controller is used to control the vibration frequency and amplitude of the vibrator, so as to achieve precise control of the feeding speed and feeding amount of the nuts.
[0041] During the operation of the vibrating bowl feeding assembly 3, the controller will adjust the vibration parameters of the vibrator according to the production requirements, so that the nuts can be discharged from the discharge port 8 at the preset feeding speed and feeding amount. This automated feeding method not only improves production efficiency, but also reduces the errors and labor intensity of manual operation.
[0042] The structure and principle of the vibrating bowl feeding assembly 3 are well-known in the field of automated feeding and have been widely used in various automated production lines. Therefore, those of ordinary skill in the art can fully understand and implement the vibrating bowl feeding assembly 3 based on the above description, which belongs to the part of the extended implementation methods known to those of ordinary skill in the art.
[0043] Subsequently, multiple nut-gripping fixtures 5 are accurately controlled by the three-axis moving mechanism 4 and respectively aligned with the discharge ports 8 of their corresponding vibrating bowl feeding assemblies 3. These nut-gripping fixtures 5 firmly clamp the nuts at the discharge ports 8 by means of magnetic attraction, negative pressure adsorption or limit clamping according to the shape, size and material characteristics of the nuts.
[0044] In this application, multiple nut-gripping fixtures 5 are installed on the three-axis moving mechanism 4, and each nut-gripping fixture 5 corresponds to a discharge port 8 of a vibrating bowl feeding assembly 3. The three-axis moving mechanism 4 accurately controls the movement of each nut-gripping fixture 5 in the X-axis, Y-axis and Z-axis directions, so that the nut-gripping fixture 5 can accurately align and move to the position of its corresponding discharge port 8.
[0045] This technology of using a three-axis moving mechanism to control the nut-gripping fixtures for precise positioning has been widely used in the field of automated production lines and is considered to be part of the prior art. Therefore, those of ordinary skill in the art can fully understand and implement the technical solution of using a three-axis moving mechanism to control multiple nut-gripping fixtures for precise positioning based on the above description.
[0046] In addition, the design of the nut fixture 5 is also based on the prior art. According to the shape, size, and material properties of the nut, methods such as magnetic adsorption, negative pressure adsorption, or clamping by limiting are used to clamp the nut. These clamping methods are also common in automated production lines and have been proven to be effective nut clamping means. Therefore, the design of the nut fixture 5 also belongs to a part of the prior art.
[0047] Furthermore, once the nut is clamped by the nut fixture 5, the three-axis moving mechanism 4 drives the fixture to move precisely in space. During this process, the three-axis moving mechanism 4 is driven by a servo motor to achieve high-precision displacement in the X-axis 9, Y-axis 10, and Z-axis 11 directions. In this way, the device can accurately transport the nuts provided by the vibratory bowl feeder assembly 3 at different positions to the nut positioning fixture 7.
[0048] At the nut positioning fixture 7, multiple nut fixtures 5 place the nuts on the fixture according to a preset layout. This layout is exactly the same as the layout of the nuts in the final injection mold, thus ensuring the smooth progress of the subsequent injection process. When all the nuts are accurately placed on the nut positioning fixture 7, the nut positioning fixture 7 will automatically loosen and release the clamping force on the nuts.
[0049] At this time, the nuts that have been positioned are in a state ready for injection. The injection molding machine can quickly inject the plastic into the mold and tightly combine the plastic with the nuts under high temperature and high pressure. Due to the precise feeding and positioning functions of the fully automatic nut feeding device, the entire injection process can be completed efficiently and accurately, greatly improving the production efficiency and product quality.
[0050] At the same time, after the nut positioning fixture 7 automatically loosens and releases the clamping force on the nuts, a manipulator well-known to those of ordinary skill in the art then enters the working state. This manipulator has high-precision grasping and moving capabilities. It can quickly and accurately grasp the nut positioning fixture 7 loaded with nuts and move it to the next process, which all belong to the known extended implementation schemes in the art.
[0051] While the manipulator moves the nut positioning fixture 7 to the next process, a new nut positioning fixture 7 has also been prepared and is placed on the fixture positioning bracket 6 by a manipulator waiting for the next use. The design of the fixture positioning bracket 6 ensures the stability and accurate positioning of the new fixture, thus making full preparations for the subsequent nut placement work.
[0052] Throughout the process, from the precise placement of nuts to the automatic release of fixtures, and then to the precise transfer by the manipulator and the accurate positioning of new fixtures, the high efficiency and precision of the automated production line are demonstrated. The application of these steps and components are all extended implementation methods well-known to those of ordinary skill in the art, which together ensure the smooth progress of the entire production process and all belong to the extended implementation methods known to those of ordinary skill in the art.
[0053] The beneficial effects brought by this utility model will be more fully demonstrated in the following specific application scenarios and methods:
[0054] 1. Significantly improve production efficiency:
[0055] Automated feeding and positioning greatly reduce the time waste in manual operations. The traditional manual nut placement method is inefficient and cannot meet the needs of large-scale production. The device of this application uses the vibrating disk feeding component 3 to quickly and orderly transport nuts, and accurately places the nuts at the predetermined position through the three-axis moving mechanism 4, significantly improving production efficiency.
[0056] 2. Reduce labor intensity and health risks:
[0057] Avoid workers working in high-temperature environments for a long time, thus reducing the risk of burns and other health problems. In the traditional injection molding process, workers need to perform manual operations next to high-temperature molds, which poses a serious threat to their physical health. The fully automated operation method completely eliminates this risk.
[0058] 3. Reduce factors of quality instability:
[0059] The precise feeding and positioning mechanism reduces the residence time of plastic in the injection molding machine, thus reducing the risk of thermal degradation and deformation of the product. Due to the errors and inconsistencies of manual operations, quality problems often occur in the plastic injection molding process, such as plastic degradation, product deformation, etc. The device of this application greatly reduces the occurrence of these quality problems through precise mechanical operations.
[0060] 4. Improve production flexibility:
[0061] The programmable three-axis moving mechanism 4 and the diverse design of the nut-gripping fixture 5 enable the device to adapt to nuts of different types and sizes. In the traditional production method, changing different types of nuts often requires a complex process of adjustment and tool replacement. However, the device of this application can adapt to different production requirements through simple program adjustments, greatly improving production flexibility.
[0062] 5. Reduce production costs:
[0063] Although the initial investment in fully automated equipment may be relatively high, in the long run, it can significantly reduce labor costs and the rejection rate, thereby lowering the overall production cost. In addition, due to the reduction of manual intervention, the maintenance cost of the equipment is also relatively low.
[0064] 6. Enhance production safety:
[0065] Automated equipment operates more stably and reliably, reducing production accidents caused by human factors. In traditional injection molding workshops, industrial accidents often occur due to worker fatigue, negligence, etc. The fully automated production method greatly reduces this risk and improves production safety.
[0066] In summary, the fully automated nut feeding device of the present application has shown significant beneficial effects in aspects such as improving production efficiency, reducing labor intensity and health risks, reducing factors causing quality instability, increasing production flexibility, reducing production costs, and enhancing production safety.
