Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a directional screening vibratory plate. Background Technology

[0002] Vibratory feeders are widely used auxiliary feeding devices in automated production. Their function is to automatically and orderly arrange and transport disordered workpieces through vibration, so as to supply subsequent assembly or processing steps.

[0003] However, traditional vibratory feeders rely primarily on purely passive mechanical structures such as fixed inclined planes, varying track widths, and baffles to screen workpieces. They remove head-first workpieces by creating a groove that only allows the workpiece's shaft to pass through. When processing high-speed flowing or irregularly shaped workpieces, these workpieces are prone to accumulating and jamming at the screening inlet due to improper posture—a phenomenon known as "stuck-up"—leading to production line interruptions requiring manual intervention and severely impacting production efficiency and stability.

[0004] To address the jamming issue, some existing technologies introduce compressed air nozzles to blow away the screened workpieces, removing those with incorrect orientations. While this alleviates jamming to some extent, the air pressure is difficult to control precisely, potentially blowing away even correctly oriented workpieces and affecting screening efficiency. Furthermore, for lightweight workpieces such as plastics, electrostatic adsorption and surface friction are another reason for their poor flowability, tendency to stick and clog, indicating that existing pneumatic solutions still have room for improvement in conveying efficiency.

[0005] Therefore, how to actively handle workpieces with incorrect orientation while preventing jamming and blockage is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The main purpose of this utility model is to provide a directional screening vibratory plate, which aims to solve the technical problems of low screening efficiency and easy jamming caused by the passive screening structure of the vibratory plate when screening rubber nails in the prior art.

[0007] To achieve the above objectives, this utility model proposes a directional screening vibratory feeder, including a vibratory feeder body and a screening component disposed inside the vibratory feeder body, the screening component comprising: A screening channel defines the path for the glued nails; A detection device for detecting misaligned rubber nails in the screening channel; A push-off device, disposed in the screening channel, is used to remove misaligned glue nails from the screening channel.

[0008] The screening channel consists of a first slot and a second circular groove formed on a circular block. The first slot and the second circular groove are connected and the entire channel is inclined. Utilizing the component of gravity, the actively driven adhesive pins with the correct orientation can pass through the screening channel smoothly and quickly, avoiding lingering or slowing down within the channel.

[0009] Furthermore, the entrance of the screening channel is provided with a circular block and at least one fan-shaped block, the fan-shaped block being movably disposed on the inner wall of the circular block to form a gap for supplying glue nail tips.

[0010] The fan-shaped blocks consist of two symmetrically arranged sets. These blocks force misaligned rubber nails to remain in the detection area, ensuring reliable triggering of the detection device. These two sets of fan-shaped blocks are movably positioned on one side of the first slot, allowing free rotation around their fulcrum and maintaining an initial closed or semi-closed state by gravity or a weak spring force. When a correctly oriented active rubber nail enters, its tip easily passes between the two fan-shaped blocks, opening them up. The active rubber nail then drives the fan-shaped blocks to rotate along the inner walls of the first and second circular slots, briefly compressing the spring force to allow the correctly oriented rubber nail to pass. When a misaligned active rubber nail arrives, because the diameter of one side of the first slot is slightly smaller than the diameter of the active rubber nail, its larger head cannot strike the fan-shaped blocks to rotate, thus being blocked at the entrance of the first slot. This ensures that only misaligned rubber nails are stably stopped at the detection position, avoiding missed detections due to excessively fast nail movement and improving detection accuracy.

[0011] Furthermore, the fan-shaped stop is rotatably connected to the inner wall of the circular block, and is rotatably connected along the radial direction of the circular block.

[0012] Furthermore, the detection device includes an inductive switch disposed on one side wall of the circular block, with the trigger end of the inductive switch extending to the detection area of ​​the fan-shaped block. The detection device is positioned in the screening channel near the fan-shaped block. When a misaligned rubber nail is blocked by the fan-shaped block, the misaligned rubber nail comes into contact with the detection device. The inductive switch, acting as the detection device, is installed directly behind the fan-shaped block, and the distance between the trigger point of the inductive switch and the blocking surface of the fan-shaped block is set to a very small value. When a misaligned active rubber nail is blocked and stops by the fan-shaped block, its front end immediately touches the inductive switch, thus blocking and detecting the rubber nail. This ensures that the detection device only responds to the screened erroneous rubber nails, avoiding misjudgment of normally passing rubber nails.

[0013] Furthermore, the push-off device includes an L-shaped push rod driven by a motor, the swing path of which covers the detection area of ​​the screening channel.

[0014] Furthermore, the screening component also includes a passive adhesive pin fixed in the screening channel, the passive adhesive pin being provided with an inclined platform for guiding the adhesive pin to pass smoothly.

[0015] Furthermore, it also includes a liquid jetting system disposed above the vibratory plate body, the liquid jetting system being used to spray liquid into the rubber nails inside the vibratory plate body.

[0016] Furthermore, the liquid injection system includes: A pipe used to store or transport liquids; At least one atomizing ring connected to the conduit, the atomizing ring being used to atomize the liquid.

[0017] Furthermore, multiple spray nozzles are uniformly arranged on the outer surface of the atomizing ring for spraying the atomized liquid onto the rubber nails.

[0018] Furthermore, the liquid injection system also includes a control knob disposed on the pipe, the control knob being used to adjust the liquid injection frequency.

[0019] The above technical solution has the following advantages: By combining the detection and pushing devices, the system can proactively identify misaligned rubber nails in the screening path and remove them immediately and actively. This replaces the traditional passive blocking or probability-based screening methods, avoiding jamming caused by misaligned rubber nails accumulating at the screening opening. This greatly improves the success rate of screening and the continuity of the feeding process, reduces manual intervention, and enhances the automation level and stability of the production line.

[0020] Furthermore, by incorporating a liquid spray system, liquids such as alcohol can be evenly sprayed onto the surface of the rubber nails. This significantly reduces surface friction and eliminates static electricity, improving the flow of the rubber nails within the vibratory feeder and resulting in smoother movement, further reducing the probability of clogging. Simultaneously, the atomizing ring design allows the liquid to adhere more evenly to all rubber nail surfaces in a mist form, saving on usage and achieving better results. The adjustable control mechanism also enables the system to adapt to rubber nails of different sizes and materials, as well as varying environmental humidity levels, making it more versatile.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0024] like Figure 1 and Figure 5 As shown, a directional screening vibratory feeder includes a vibratory feeder body 1 and a screening component disposed inside the vibratory feeder body 1. The screening component includes a screening channel that defines the path of the rubber nails; a detection device for detecting rubber nails with incorrect orientation in the path; and a push-off device that is linked to the detection device and is used to remove the rubber nails with incorrect orientation from the path.

[0025] The vibratory feeder body 1 is a standard vibratory feeder structure, with an internal spiral track rising from the bottom of the feeder to the top, as shown in the attached diagram. Figure 1 The spiral-shaped track and the vibratory feeder body 1 are technical solutions known to those skilled in the art, and will not be described in detail here. When the vibratory feeder body 1 is working, the active rubber nails 19 inside the feeder will move upward from the bottom of the vibratory feeder body 1 along the spiral track under the action of vibration.

[0026] In the active adhesive nail 19 of this application, one end is a pointed tip and the other end is a flat surface. When the pointed tip moves down along the screening channel, this application defines it as the correct falling direction. When the flat surface moves down along the screening channel, this application defines it as the incorrect falling direction.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5In this embodiment, the screening component is specifically a circular block 2 installed inside the vibratory feeder body 1. The circular block 2, as the screening component of this application, is fixedly installed on the inner wall of the vibratory feeder body 1 and precisely positioned along the path of the spiral track. It is typically placed at the end of the spiral track, near the final discharge port. To ensure that all active rubber nails 19 moving along the track must pass through the screening channel of the circular block 2, preventing any unscreened rubber nails from directly entering the discharge port, thus ensuring the comprehensiveness and reliability of the screening, in this embodiment, the circular block 2 is preferably placed in the forward direction of the active rubber nails 19, such as... Figure 5 There are 19 active adhesive nails.

[0028] The circular block 2 is fixedly connected to the inner wall of the vibratory feeder body 1, such as by bolts. This involves creating corresponding threaded holes on the inner wall of the vibratory feeder body 1 and using bolts to fasten the circular block 2 to the inner wall through these holes. Alternatively, the circular block 2 can be integrally fixed to the metal vibratory feeder body 1 by welding. For mass production, the circular block 2 can even be integrated as part of the vibratory feeder track, integrally formed during the casting or machining of the vibratory feeder body 1.

[0029] The circular block 2 ensures that its internal first slot 4 and second circular slot 7 are functionally an essential part of the spiral track. Specifically, the end of the spiral track is smoothly aligned and connected with the inlet of the first slot 4, while the outlet of the screening channel is connected to the track section leading to the final discharge port, ensuring that the active adhesive nail 19 moves smoothly and unimpeded from the main track to the screening component, without creating new jamming points due to structural steps or misalignments.

[0030] like Figure 2 and Figure 3 As shown, the screening channel consists of a first slot 4 and a second circular groove 7 formed on the circular block 2. The first slot 4 and the second circular groove 7 are connected and are inclined as a whole. Utilizing the component of gravity, the active adhesive nail 19 with the correct directional assistance can pass through the screening channel smoothly and quickly, avoiding stopping or slowing down in the screening channel. Specifically, when the active adhesive nail 19 gradually descends along the spiral track and passes through the circular block 2, if the direction of descent of the active adhesive nail 19 is correct, it can pass through the circular block 2 smoothly. If the direction of descent is incorrect, it will be blocked on the screening channel and wait for the pushing device to remove it. The specific implementation method can be seen in the following embodiment.

[0031] like Figure 2As shown, the detection device includes an inductive switch 6 disposed on one side wall of the circular block 2. The trigger end of the inductive switch 6 extends to the detection area of ​​the fan-shaped block 5. In this embodiment, the detection device is a mechanical inductive switch 6, which is essentially a trigger rod of a micro switch. Mechanical switches are simple in structure, reliable in operation, and economical in cost, making them very suitable for industrial environments. The inductive switch 6 is fixed to one side of the first slot 4, its position facing the forward direction of the active rubber nail 19. When an active rubber nail 19 in the wrong direction passes through the first slot 4, its larger head will collide with and press the inductive switch 6. After the inductive switch 6 is pressed, the micro switch connected to it closes, generating an electrical signal as a trigger signal for detecting the incorrect rubber nail, providing an electrical signal for triggering the subsequent pushing device.

[0032] like Figure 2 and Figure 5 As shown, the pushing device includes an L-shaped push rod 3 driven by a motor. The swing path of the L-shaped push rod 3 covers the detection area of ​​the screening channel. In this embodiment, the pushing device is an L-shaped push rod 3, which is movably mounted on one side of the circular block 2 and connected to an external micro motor, such as a stepper motor or a DC geared motor. The L-shaped push rod 3 can provide an effective pushing surface, and its rotation can push the active glue nail 19 away from the screening channel. The control circuit of the L-shaped push rod 3 is connected to the output terminal of the aforementioned inductive switch 6. When the inductive switch 6 generates a trigger signal, the control circuit drives the motor to rotate by a preset angle, causing the L-shaped push rod 3 to swing. The movement trajectory of the L-shaped push rod 3 enables it to push the erroneously oriented active glue nail 19, which is stuck at the first slot 4, away from the screening channel, causing it to fall back to the bottom of the vibrating plate body 1 to rejoin the sorting. This achieves automated and active removal of erroneous glue nails, preventing the accumulation and jamming of subsequent glue nails.

[0033] This second embodiment provides a non-contact sensing-based implementation. The structure of the screening channel is basically the same as in the first embodiment. In this embodiment, the detection device uses a photoelectric sensor. The photoelectric sensor is a non-contact detection method, with no mechanical wear, faster response speed, and longer service life. A through-beam or diffuse reflection photoelectric sensor is installed on one side of the first slot 4. The optical path of the sensor is set at the height through which the head of the active adhesive nail 19 passes. When the tip of the active adhesive nail 19 in the correct direction passes, its smaller rod will not block or will only briefly block the optical path, and no trigger signal will be generated. When the active adhesive nail 19 in the wrong direction arrives, its larger head will completely block the optical path for a period of time, thereby triggering the sensor to output a high-level signal. This achieves rapid, non-contact detection of incorrect adhesive nails.

[0034] In this embodiment, the pushing device is a high-speed solenoid valve-controlled air nozzle. The pneumatic pushing response is extremely fast, the force is gentle, and it is unlikely to damage the rubber nails. The air nozzle is installed on the side of the screening channel, and its air path is connected to a compressed air source through a high-speed solenoid valve. The control terminal of the solenoid valve is connected to the output terminal of the aforementioned photoelectric sensor. When the photoelectric sensor detects an erroneous rubber nail and outputs a high-level signal, this signal triggers the solenoid valve to open instantaneously. The ejected compressed air blows the erroneous rubber nail away from the screening channel, achieving rapid pushing away of the erroneous rubber nail and further improving processing efficiency.

[0035] At least one fan-shaped block 5 is provided at the entrance of the screening channel. The fan-shaped block 5 is movably disposed on the inner wall of the circular block 2 to form a gap for the tip of the glue nail. The fan-shaped block 5 only allows the glue nail that is facing the correct direction to pass through and move, while blocking glue nails that are facing the wrong direction.

[0036] Reference Figure 2 and Figure 3 In this embodiment, the fan-shaped stop 5 consists of two symmetrically arranged sets of fan-shaped stop blocks 5. These two sets of fan-shaped stop blocks 5 force the misaligned rubber nails to remain in the detection area. The fan-shaped stop blocks 5 are rotatably connected to the inner wall of the circular block 2 and rotate along the radial direction of the circular block 2, ensuring that the detection device can be reliably triggered. These two sets of fan-shaped stop blocks 5 are movably arranged on one side of the first slot 4, and can rotate freely around their fulcrum, maintaining an initial closed or semi-closed state by gravity or a weak spring force. Figure 2 The dotted line represents the axis of rotation, and the direction of rotation is indicated by the arrow. When a correctly oriented active rubber nail 19 enters, its tip can easily pass between the two fan-shaped blocks 5 and open them up. At this time, the active rubber nail 19 will drive the fan-shaped blocks 5 to rotate along the inner wall of the first slot 4 and the second circular slot 7 through the component of gravity. The active rubber nail 19 will gradually move towards the center of the circular block 2, increasing the cross-sectional area for the active rubber nail 19 to pass through. The spring force of the fan-shaped blocks 5 is briefly compressed, allowing the correctly oriented rubber nail to pass through. When an incorrectly oriented active rubber nail 19 arrives, because the diameter of one side of the first slot 4 is slightly smaller than the diameter of the active rubber nail 19, its larger head cannot hit the fan-shaped blocks 5 and cannot force the fan-shaped blocks 5 to rotate, thus being blocked at the entrance edge of the first slot 4. This ensures that only incorrectly oriented rubber nails will be stably stopped at the detection position, avoiding missed detections caused by excessively fast movement of the rubber nails and improving the accuracy of detection.

[0037] The detection device is located near the fan-shaped block 5. When the wrong-directioned rubber nail is blocked by the fan-shaped block 5, the rubber nail comes into contact with the detection device.

[0038] like Figure 2As shown, in this embodiment, the inductive switch 6 serves as a detection device and is installed directly behind the fan-shaped block 5. The distance between the trigger point of the inductive switch 6 and the blocking surface of the fan-shaped block 5 is set to a very small value. When the erroneous active rubber nail 19 is stopped by the fan-shaped block 5, its front end immediately touches the inductive switch 6, thus blocking and detecting the rubber nail. This ensures that the detection device only responds to the erroneous rubber nails that have been selected, avoiding misjudgment of normally passing rubber nails.

[0039] like Figure 2 As shown, the push-away device includes an L-shaped push rod 3 driven by a motor. When the detection device is triggered, the motor is started to drive the L-shaped push rod 3 to move.

[0040] In this embodiment, the pushing device is an L-shaped push rod 3, powered by an external motor. The motor drive provides a stable and controllable pushing torque and motion trajectory. Compared to simple springs or electromagnets, its repeatability and reliability are higher. The inductive switch 6 is located on one side of the circular block 2, and its output is connected to the motor of the L-shaped push rod 3 via a controller or control circuit. Specifically, a control unit, such as a microcontroller or PLC, receives the switching signal from the inductive switch 6. Once the control unit receives the signal, it immediately executes a preset program, sends a command to the motor driver, controls the motor to start, and drives the L-shaped push rod 3 to rotate, completing the pushing action. Then, it reverses back to the initial position, waiting for the next trigger, thereby achieving automated removal of faulty adhesive nails.

[0041] like Figure 5 As shown, the screening component also includes a fixed passive adhesive pin 16 with an inclined platform 17 on it to guide the adhesive pin through smoothly and prevent it from getting stuck.

[0042] A passive rubber nail 16 is fixedly installed at a specific location in the screening channel. One end of the passive rubber nail 16 has a fixed inclined platform 17, and the other end of the inclined platform 17 has a fixed rubber nail head 18. This avoids structural dead angles or gaps in the path of the rubber nail. The passive rubber nail 16 is fixedly installed in the screening channel, and the inclined platform 17 forms a smooth guiding surface. When the active rubber nail 19 approaches the passive rubber nail 16 during vibration, it contacts the inclined platform 17 and, under the guidance of the vibration and the inclined surface, is offset from the passive rubber nail 16, preventing it from getting stuck on the inclined platform 17. This solves the potential jamming risk during active screening and improves the smoothness and reliability of the entire feeding system.

[0043] like Figure 1 and Figure 4 As shown, this application also includes a liquid jetting system disposed above the vibratory plate body 1 for jetting liquid into the rubber nails inside the vibratory plate body 1.

[0044] At the upper end of the vibratory feeder body 1, a liquid spraying system is supported and fixed by two sets of fixed L-shaped connecting rods 8. Friction and static electricity on the surface of the plastic nails are important reasons for their poor flowability, easy adhesion, and clogging. This application mainly includes a pipe 9 for conveying liquid, which is connected to an external liquid storage tank (not shown) via a water inlet pipe 10 fixed to its outer surface. The end of the pipe 9 extends to the upper center of the vibratory feeder body 1, providing a wider spraying range for subsequent surface treatment of all active plastic nails 19 in the feeder. The sprayed active plastic nails 19 have a smooth surface, making them easy to move.

[0045] like Figure 4 As shown, the liquid injection system includes a pipe 9 for storing or transporting liquid; at least one atomizing ring 14 connected to the pipe 9 for atomizing the liquid.

[0046] Multiple sets of annular atomizing rings 14 are fixedly installed on the outer surface of the pipe 9. Compared with direct liquid jetting, atomization disperses the liquid into extremely fine droplets. The liquid enters from the inlet pipe 10, passes through the interior of the pipe 9, and is delivered to the internal cavity of the atomizing rings 14. The atomizing rings 14 atomize the liquid through their special internal structure, such as a Venturi tube structure, so that the active rubber nails 19 inside the vibratory feeder body 1 receive more comprehensive alcohol spraying. This achieves maximum coverage with minimal liquid consumption, ensuring that most of the active rubber nails 19 inside the feeder are uniformly coated with a thin liquid film, and that excessive liquid does not affect the normal operation of the vibratory feeder.

[0047] As a further embodiment of this application, the atomizing ring 14 can integrate ultrasonic atomization technology. A piezoelectric ceramic ultrasonic transducer is installed on or near the atomizing ring 14. When the controller applies a high-frequency electrical signal to the transducer, the resulting high-frequency mechanical vibration is transmitted to the liquid, breaking it into finer and more uniform droplets. The droplets produced by ultrasonic atomization have smaller particle sizes, better eliminate static electricity, and have almost no splashing, resulting in better coverage. This achieves more efficient and uniform surface treatment, and is particularly suitable for feeding micro-electronic components that are highly sensitive to static electricity.

[0048] like Figure 4 As shown, multiple spray nozzles 15 are evenly arranged on the outer surface of the atomizing ring 14 for spraying the atomized liquid onto the rubber nails.

[0049] Each atomizing ring 14 has multiple spray nozzles 15 evenly distributed on its outer surface. The purpose of this is to evenly distribute the atomized liquid throughout the entire internal space of the vibratory feeder. The spray nozzles 15 are tiny holes, their orientation designed to cover different areas of the active rubber nails 19 below. A water inlet pipe 10 passes through the interior of the pipe 9 and connects to these spray nozzles 15. Under the pressure within the atomizing ring 14, the atomized liquid is directly and evenly sprayed from these spray nozzles 15, ensuring that the active rubber nails 19 from the center to the edge are covered by the liquid mist, achieving a thorough surface treatment of all rubber nails within the feeder.

[0050] like Figure 4 As shown, the liquid injection system also includes a control knob 11 for adjusting the liquid injection frequency.

[0051] A rotatable control knob 11 is movably installed at the upper end of pipe 9. Because different materials and sizes of rubber nails generate varying degrees of static electricity and surface adhesion under different temperature and humidity conditions, the required liquid spray volume also varies. A flow control valve is internally connected to the control knob 11. Three sets of speed adjustment lines 12 are provided on the outer surface of the control knob 11, corresponding to the alignment lines 13 fixed to the outer surface of pipe 9. By rotating the control knob 11, the operator aligns different speed adjustment lines 12 with the alignment lines 13, thereby setting different valve openings and adjusting the alcohol spray frequency and speed. This provides an intuitive and convenient manual adjustment method, enabling the equipment to quickly adapt to different production needs.

[0052] As an improved embodiment, the liquid jetting system can employ intelligent control. The original control knob 11 is replaced by an integrated controller. This controller is connected to a piezoelectric weight sensor mounted on the bottom of the vibratory plate body 1 and a vision recognition system. This allows for automatic adjustment of the jetting volume based on actual working conditions. The weight sensor monitors the total amount of active adhesive nails 19 within the plate in real time, while the vision system identifies the accumulation of adhesive nails. Based on the input signals from these sensors, the controller automatically adjusts the output flow rate of the liquid pump or the jetting duty cycle through an algorithm. For example, when a large number of adhesive nails or localized accumulation is detected in the plate, the jetting volume is automatically increased; when the number of adhesive nails is small, the jetting volume is reduced, and jetting may even stop when the plate is empty. This achieves closed-loop intelligent control of the liquid jetting system, not only saving liquid consumption but also ensuring optimal surface treatment results under any working conditions.

[0053] The sprayed liquid is alcohol, used to increase the smoothness of the glued nail surface.

[0054] In this embodiment, the liquid supplied to the system through the inlet pipe 10 is specifically industrial alcohol. Alcohol has good wetting properties and can quickly spread on the surface of the adhesive nails; it can also effectively eliminate static electricity; in addition, alcohol evaporates quickly and will not leave liquid residue on the adhesive nails or equipment, avoiding the impact on subsequent welding, spraying and other processes and the corrosion of equipment. By using alcohol as a treatment fluid, the flowability of the active adhesive nails 19 is effectively improved while ensuring the cleanliness and compatibility of the process, making it an ideal medium choice.
