[0017] Some embodiments of this disclosure provide a placement device for three-color extruded products, which can improve the efficiency of three-color extruded product placement. Specifically, the reason for the low efficiency of most three-color extruded product placement is that, currently, in order to batch spray three-color extruded products, they are often manually placed on a needle plate before spraying. This leads to the low efficiency of most three-color extruded product placement.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Figure 1 This is a schematic diagram of the structure of a placement device for three-color extruded products according to some embodiments of this disclosure. Figure 1 It includes 1. hopper, 2. hose, 3. vibratory plate, 4. vibratory slide, 5. cylinder, 6. suction nozzle, 7. tray, 8. needle plate, 9. slide rail, and 10. extension structure.

[0029] Figure 2 This is a cross-sectional view of a suction nozzle according to some embodiments of the present disclosure. Figure 2 It includes an air hole 11, a pneumatic part 12, a contact part 13, and a receiving groove 14.

[0030] In some embodiments, the aforementioned three-color extruded product placement device includes a hopper 1, a vibration unit, a base assembly, a pneumatic assembly, a sliding assembly, a needle plate 8, and a control assembly. The hopper 1 is used to store the material to be placed. This material can be a three-color extruded product or other products of similar shape and size. The three-color extruded product can be a conductive component made of three synthetic materials; the specific color will vary depending on the type and ratio of materials, but its dimensions remain essentially unchanged. When placing three-color extruded products of different specifications, only some parts of the placement device (such as the vibrating plate, nozzle, etc.) need to be adjusted accordingly for continued use. The lower end of the hopper 1 may have a hole to allow material to flow out, preparing for subsequent conveying. The hopper 1 can be a funnel shape, wider at the top and narrower at the bottom, to facilitate the natural downward flow of material under gravity. It can be welded from stainless steel, providing good wear resistance and corrosion resistance, and can adapt to different types of materials. The inner wall of the hopper 1 can be designed with a smooth surface and can also be coated with an anti-stick coating, such as a Teflon coating, to reduce material adhesion and clogging. The aforementioned vibration unit may include a vibratory plate 3 and a vibratory slide 4. The vibratory plate 3 can be installed below the hopper 1, and its lower end may have a limiting hole. One end of the vibratory slide 4 can be installed below the limiting hole. The vibratory plate 3, through its own vibration, can transport each piece of material flowing out of the hopper 1 through the limiting hole to the vibratory slide 4. The vibratory plate 3 can be driven by an electromagnetic vibrator. The electromagnetic vibrator operates based on the principle of electromagnetic induction. It consists of an electromagnet, an armature, and a spring plate. When an alternating current is applied to the electromagnet, a periodically changing magnetic field is generated, attracting the armature to drive the spring plate to vibrate, thereby causing the entire vibratory plate 3 to vibrate. The limiting hole can be located at the bottom outlet of the vibratory plate 3, and its shape can be adapted to the shape of the material, such as circular or square. The size of the hole is slightly larger than the size of the material, ensuring smooth passage of the material while restricting its position within the vibratory slide 4. An example is provided below to illustrate the working principle of the limiting hole. Assuming the material is a cylinder with a diameter of 3mm and a height of 1cm, the aforementioned limiting hole can be a circular hole with a diameter of 4mm. During the vibration of the vibrating plate 3, the material can slide vertically from the limiting hole onto the vibrating track 4. The vibrating track 4 can be a long, narrow groove structure, made of stainless steel or engineering plastic. The inner surface of the groove is smooth to reduce friction during the sliding process. The vibrating track 4 can also be driven by the aforementioned electromagnetic vibrator. The vibrating track 4, through its own vibration, can transfer the material from the vibrating plate 3 to below the cylinder 5, providing conditions for the pneumatic assembly to grasp the material.

[0031] In some embodiments, the pneumatic assembly may include a cylinder 5, an air pump, and a suction nozzle 6. The suction nozzle 6 is mounted on the cylinder 5, and the cylinder 5 and the air pump are connected via an air pipe. The air pump is an air source device responsible for generating compressed air. It is connected to the cylinder 5 via an air pipe, providing power for the cylinder 5's operation and ensuring its normal functioning. The air pump can be a piston type, diaphragm type, or screw type, and no specific limitation is made here. The cylinder 5, as an actuator, converts the pressure energy of compressed air into mechanical energy. The shape of the suction nozzle 6 can be designed according to the material shape; for example, it can be a circular suction cup, a square suction cup, or an irregularly shaped suction cup. For small cylindrical materials, a circular suction cup with an inner diameter slightly larger than the outer diameter of the material can be used. The suction cup material can be stainless steel, which has good wear resistance. The suction nozzle 6 may have an internal vent, communicating with the air source of the cylinder 5, to adsorb materials through negative pressure.

[0032] In some embodiments, the cylinder 5 can be mounted on the sliding assembly, and the other end of the vibration slide 4 can be mounted below the cylinder 5. It should be noted that the sliding assembly is not shown in the accompanying drawings. The core component of the sliding assembly can be a ball screw. The screw can be made of alloy steel, precision ground to achieve high surface hardness and high thread precision. A nut engages with the screw and contains balls; when the screw rotates, the nut moves linearly along the screw via the balls. A mounting seat is provided on the nut for connecting the cylinder 5, converting the rotational motion of the screw into the linear motion of the cylinder 5. This transmission method has the advantages of high transmission efficiency and high positioning accuracy. To drive the screw rotation, a dedicated motor, such as a stepper motor or a servo motor, can be used. Stepper motors are less expensive and suitable for applications with relatively low precision requirements; servo motors offer higher precision and response speed, making them suitable for high-precision applications.

[0033] In some embodiments, the base assembly may include a tray 7 and a slide rail 9, with the tray 7 slidably connected to the slide rail 9. Similar to the sliding assembly, the slide rail 9 is driven by a motor-driven lead screw, which in turn drives the tray 7 to slide. The tray 7 may be a flat structure, made of aluminum alloy, steel, or engineering plastic. The bottom of the tray 7 may be bolted to the slider of the slide rail 9 (similar to the mounting base of the sliding assembly), allowing the tray 7 to slide freely on the slide rail 9. The needle plate 8 is detachably mounted on the tray 7. The needle plate 8 may be flat, made of stainless steel, aluminum alloy, or engineering plastic. The needle plate 8 may have a predetermined number (e.g., 35×35) of needle-like protrusions evenly distributed according to material placement requirements. The number of needle-like protrusions is not specifically limited here. The needle-like protrusions can be used to support and position materials, preventing them from moving on the needle plate 8.

[0034] In some embodiments, the control component can be communicatively connected to the base assembly, the pneumatic assembly, and the sliding assembly, respectively. The control component can consist of a controller (such as a PLC or microcontroller), sensors, drivers, and an operation panel. The controller is the core of the control component, responsible for receiving sensor signals, processing data, and issuing control commands. Sensors are used to detect the operating status of various parts of the device; for example, a position sensor can detect the position of cylinder 5 and tray 7, a pressure sensor can detect the output pressure of the air pump, and an infrared sensor can detect whether the material has reached a fixed position. Drivers are used to drive actuators; for example, a motor driver controls the operation of the motor, and a solenoid valve driver controls the movement of cylinder 5. The operation panel is used by operators to input commands and monitor the operating status of the equipment, and may include a display screen, an emergency stop button, etc. For ease of understanding, the workflow of the above-mentioned three-color extrusion product placement device will now be explained. Figure 1 Taking the illustrated structure as an example, when material (such as a cylindrical three-color extruded product) enters the vibratory feeder 3 from the hopper 1, the vibratory feeder 3 continuously vibrates, causing the material to fall onto the vibratory slide 4 from the limiting hole in the same posture (e.g., each cylindrical three-color extruded product is in a vertical posture). Since the vibratory slide 4 is continuously vibrating (e.g., linearly vibrating along the material's direction of travel), the material will slide from the end of the vibratory slide 4 closest to the vibratory feeder 3 to the other end (i.e., the end closest to the suction nozzle 6). When the infrared sensor detects the material, the cylinder 5 starts working, pushing the suction nozzle 6 downward and simultaneously providing suction to the suction nozzle 6 to pick up the material. Then, the sliding assembly can drive the cylinder with the material to move laterally until it moves to the position corresponding to the tray 7 (at this time, the needle plate 8 should be placed on the tray 7). Then, the cylinder 5 pushes the suction nozzle 6 downward, causing the material to be inserted into the needle plate 8. Assuming there are 3×3=9 needles on the needle plate 8, arranged in three rows and three columns, the controller (with a pre-programmed control program) can move the sliding component to insert the material into the three needles of the first row. When switching rows, the controller (with a pre-programmed control program) can move the tray 7 along the slide rail 9. Thus, the three-color extrusion product placement device can automatically place the material onto the needle plate 8.

[0035] Optionally, such as Figure 1 As shown, a flexible hose 2 can be connected below the hole on the hopper 1, and the flexible hose 2 matches the hole. The flexible hose 2 can directly convey the material to the bottom of the vibrating plate 3 to prevent the material from being shaken out by the vibrating plate 3 when it is conveyed from the hopper 1 to the vibrating plate 3.

[0036] Optionally, such as Figure 1 As shown, the aforementioned hose 2 can be located inside the aforementioned vibratory plate 3. A flexible baffle structure is provided at the upper opening inside the aforementioned vibratory plate 3. The aforementioned flexible baffle structure is also to prevent the material from being vibrated out by the aforementioned vibratory plate 3 when it is conveyed from the aforementioned hopper 1 to the aforementioned vibratory plate 3. The aforementioned flexible baffle structure can be made of rubber, and no specific limitation is made here.

[0037] Optionally, both the vibratory plate 3 and the vibratory slide 4 can be connected to a vibratory motor. That is, both the vibratory plate 3 and the vibratory slide 4 can be driven by a vibratory motor. The vibratory motor drives the eccentric block to rotate, generating centrifugal force, thereby causing the vibrating body to vibrate.

[0038] Optionally, the needle plate 8 may include a linkage mechanism. It should be noted that the linkage mechanism is not shown in the accompanying drawings. The linkage mechanism connects all the needles on the needle plate 8 together. The linkage mechanism may include a main link, a secondary link, and a support link. The main link may be a metal rod, and its material is not specifically limited, as long as it is a rod-shaped structure with sufficient strength. The number of main links may be at least one. The secondary links may also be metal rods, and their number is not specifically limited. The function of the secondary links is to connect needles in the same column together, while the function of the main links is to connect each secondary link connected to each column of needles together. Therefore, the secondary links and the main links can be arranged in a cross pattern, and the main links and each of the secondary links can be connected together by welding or other methods. The specific connection method can be determined based on the materials of the main links and the secondary links, and is not specifically limited here. The support link may also be a metal rod. The aforementioned support link can be connected to the aforementioned main link, and the axial direction of the support link can be perpendicular to the plane formed by the intersection of the main link and the secondary link. That is, the axial direction of the support link can be parallel to the axial direction of the needle on the needle plate 8. This design is primarily to enable the needles on the needle plate 8 to extend and retract. To accommodate this design, the needle plate 8 can be a square, hollow plate structure. One side of the plate structure can have needle holes, each corresponding to a needle, and the other side has a hole through which the support link can pass. The linkage mechanism is installed inside the plate structure. The support link can be supported by a spring (the spring is sleeved on the support link, with one end abutting against the intersection of the main link and the secondary link, and the other end abutting against the bottom surface of the plate structure). When it is necessary to remove the placed material from the needle plate 8, simply pull the support link to allow the material to fall off. In addition, when cleaning the needle plate 8, the retractable needles can all retract into the needle plate 8, making the surface of the needle plate 8 flat and facilitating the cleaning of debris, dust, etc. on the needle plate 8.

[0039] Optionally, such as Figure 1 As shown, the upper end of the vibratory feeder 3 may be provided with an extension structure 10. The extension structure 10 may be a funnel-shaped structure extending outward from the upper end of the vibratory feeder 3. The extension structure 10 can increase the diameter of the vibratory feeder 3, further preventing material from being shaken out of the vibratory feeder 3 during vibration.

[0040] Optionally, such as Figure 2 As shown, the suction nozzle 6 can be integrally formed. The suction nozzle 6 may include a contact portion 13 and a pneumatic portion 12. The contact portion 13 refers to the end used for contacting the material. The pneumatic portion 12 refers to the part for gas flow. The contact portion 13 can have a square structure and may have a cylindrical receiving groove 14 inside. The receiving groove 14 can be used to hold the material adsorbed by the suction nozzle. The receiving groove 14 can be a cylindrical groove provided on the contact portion 13. This design is for adsorbing cylindrical materials; the receiving groove 14 can limit the material, to a certain extent preventing the material from bending during placement (i.e., the process of inserting it into the needle plate 8), thus affecting the placement effect. The pneumatic portion 12 can have a cylindrical structure for easy connection to the air tube. The pneumatic portion 12 may have at least two air holes 11 inside, and the air holes 11 can be distributed along the same circumference. This arrangement is mainly to handle materials with holes in the middle. Assume the material is cylindrical with a hole in the middle. If the position of pore 11 corresponds to the position of the pore on the material, a negative pressure environment cannot be formed, and thus the purpose of adsorbing the material cannot be achieved.

[0041] Optionally, the aforementioned sliding component can be mounted on the support component. The support component can be a height-adjustable platform structure (e.g., a scissor lift platform), so that the vertical stroke of the suction nozzle 6 can be adjusted by adjusting the height of the support component to accommodate materials of different heights.

[0042] Optionally, the vibrating slide 4, installed below the cylinder 5, may have a sealing structure at one end. Since the vibrating slide 4 can be a long, narrow groove, materials can be arranged on it during use. The sealing structure can be a structure that fills and flattens the groove to restrict the displacement of materials on the vibrating slide 4. The position of the sealing structure can be set with reference to the position of the suction nozzle 6, so that when the material slides to the position contacting the sealing structure, the suction nozzle 6 can pick up the material. The sealing structure can be a soft rubber stopper that matches the groove structure.

[0043] Optionally, the aforementioned sliding assembly may include a sliding rail, a drive motor, a threaded rod, and a slider. The sliding rail serves as the fundamental support and guide component of the entire sliding assembly. The sliding rail may have an I-shaped cross-section, which enhances its structural strength, ensuring stability and preventing deformation when bearing the weight of the slider and cylinder 5. Alternatively, an I-shaped groove can be provided at the bottom of the slider to fit into the sliding rail, further improving its guiding accuracy. The surface of the sliding rail may undergo high-precision grinding or lapping to achieve a certain degree of straightness and flatness, providing a foundation for smooth sliding of the slider. The length of the sliding rail can be determined based on the required sliding stroke of the cylinder 5 in the actual application scenario, ensuring smooth movement of the cylinder 5 along the rail throughout the entire operation. The drive motor can be fixed to one side of the sliding rail as a power source. It can communicate with the control component, receiving commands from it and precisely adjusting the output speed according to different operational requirements, thereby achieving precise control of the sliding position of the cylinder 5. The aforementioned drive motor can be a stepper motor or a servo motor, without specific limitations. The aforementioned threaded rod can be a rod-shaped structure with threads on its surface. One end of the aforementioned threaded rod can be connected to the aforementioned drive motor, and when the aforementioned drive motor operates, it drives the aforementioned threaded rod to rotate. The aforementioned threaded rod can pass through the threaded hole on the aforementioned slider, thereby converting the rotational motion of the aforementioned drive motor into the linear motion of the aforementioned slider. The aforementioned slider is the component that directly supports and drives the movement of the cylinder 5, and it can be provided with a pipe hole and a threaded hole. The aforementioned threaded hole cooperates with the aforementioned threaded rod, and under the drive of the aforementioned threaded rod, the aforementioned slider can slide linearly along the aforementioned sliding track. The aforementioned pipe hole is used for the passage of the aforementioned air pipe. The aforementioned pipe hole can be a circular hole opened on the aforementioned slider, and its size can be just large enough for the aforementioned air pipe to pass through. The aforementioned air pipe can be connected to the aforementioned cylinder 5 through the aforementioned pipe hole, providing compressed air to the aforementioned cylinder 5, ensuring the normal operation of the aforementioned cylinder 5, and at the same time, to a certain extent ensuring that the aforementioned air pipe will not be affected by excessive bending or displacement during the movement of the aforementioned slider, thus preventing air supply.

[0044] Further reference Figure 3 , Figure 3 This is a schematic diagram of the structure of a vibratory feeder according to some embodiments of this disclosure. Figure 3 It includes a vibratory plate 3, an extension structure 10, a limiting seat 15, an anti-slip ridge 16, and a limiting part 17.

[0045] Optionally, the aforementioned limiting hole can be located on the aforementioned limiting seat 15. The aforementioned limiting seat 15 can include a connecting part and a limiting part 17. The aforementioned connecting part can be a cylindrical structure, and its outer surface can be provided with an anti-slip ridge 16. The aforementioned anti-slip ridge 16 refers to a strip-shaped protrusion provided in the axial direction of the aforementioned connecting part. The aforementioned connecting part can be provided with a connecting thread. It should be noted that the aforementioned connecting thread only refers to the thread provided on the aforementioned connecting part, and is no different in shape from a conventional thread. The lower end of the aforementioned vibratory plate 3 can be provided with an opening, and a vibratory plate thread matching the aforementioned connecting thread is provided at the opening. The aforementioned connecting part can be used to install the aforementioned limiting seat 15 on the aforementioned vibratory plate 3 by screwing the aforementioned connecting thread and the aforementioned vibratory plate thread. The aforementioned anti-slip ridge 16 can play an anti-slip role during the user's manual screwing process. The aforementioned limiting part 17 can be provided with a preset shaped cylindrical structure, and the opening of the aforementioned cylindrical structure is the aforementioned limiting hole. The aforementioned preset shape can be preset according to the shape of the material. For example, if the material to be processed is cylindrical, the shape of the aforementioned cylindrical structure can be preset to cylindrical, and the opening can be circular. The aforementioned limiting seat 15 can be open at both ends. This is mainly to ensure that the material can be successfully output from the aforementioned vibratory feeder 3. The purpose of setting the aforementioned limiting seat 15 is that when processing different types of materials, it is not necessary to replace the entire vibratory feeder 3; the limiting seat 15 with the corresponding cylindrical structure can be replaced according to the shape of the material. This can improve the versatility and flexibility of the aforementioned vibratory feeder 3. In actual production scenarios, enterprises often need to process various types and specifications of materials. In the past, to adapt to different materials, it may be necessary to frequently replace the entire vibratory feeder 3, which is not only costly but also cumbersome and time-consuming, seriously affecting production efficiency. With the design of replaceable limiting seats 15, enterprises only need to quickly replace the corresponding limiting seat 15 according to the shape of the material.

[0046] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "low versatility of vibratory feeders". The factors leading to the low versatility of vibratory feeders are as follows: vibratory feeders are usually integrally molded, and the limiting holes on them cannot be modified. If different materials need to be processed, the entire vibratory feeder needs to be replaced. Solving these factors improves the versatility of the vibratory feeder. To achieve this effect, this disclosure also provides a design with a replaceable limiting seat. The limiting seat can be easily mounted and dismounted from the vibratory feeder, and the limiting seat can carry limiting holes of different shapes. This improves the versatility of the vibratory feeder.

[0047] Some embodiments of this disclosure provide a placement device for three-color extruded products, which can improve the efficiency of three-color extruded product placement. Specifically, the reason for the low efficiency of most three-color extruded product placement is that, currently, in order to batch spray three-color extruded products, they are often manually placed on a needle plate before spraying. This leads to the low efficiency of most three-color extruded product placement. Based on this, some embodiments of this disclosure provide a three-color extruded product placement device, which includes a hopper, a vibration unit, a base assembly, a pneumatic assembly, a sliding assembly, a needle plate, and a control assembly. The vibration unit includes a vibrating disc and a vibrating slide. The lower end of the hopper has a hole, and the vibrating disc is installed below the hopper. The lower end of the vibrating disc has a limiting hole, and one end of the vibrating slide is installed below the limiting hole. The pneumatic assembly includes a cylinder, an air pump, and a suction nozzle, wherein the suction nozzle is installed on the cylinder, and the cylinder and the air pump are connected via an air pipe. The cylinder is installed on the sliding assembly, and the other end of the vibrating slide is installed below the cylinder. The base assembly includes a tray and a slide rail, and the tray is slidably connected to the slide rail. The needle plate is detachably installed on the tray. The control assembly is communicatively connected to the base assembly, the pneumatic assembly, and the sliding assembly. Because the aforementioned three-color extruded product placement device can automatically place the three-color extruded products through the cooperation of the cylinder, sliding component, and base component, the efficiency of three-color extruded product placement can be improved.
