[0044] Please refer to Figures 1-6 One embodiment of this utility model provides an automatic replenishment mechanism to solve the problems of inaccurate detection of product gaps and easy omissions in existing manual replenishment, as well as the high labor intensity and fatigue caused by the high labor intensity of replenishment.

[0045] Specifically, please refer to Figure 1 This is a perspective view of an automatic feeding mechanism provided by an embodiment of the present invention. The present invention provides an automatic feeding mechanism, including: a frame 10, a conveying module 20, an empty material detection module 30, a feeding module 40, and a feeding module 50, which realizes precise control of the feeding amount and position, improves the quality of finished products, reduces reliance on manual labor, avoids insufficient or incorrect feeding due to human negligence, and saves labor costs.

[0046] Specifically, the conveying module 20 is disposed near the side wall of the frame 10. The conveying module 20 includes a first guide rail 21 and a second guide rail 22 arranged in parallel. A replenishing tray 23 is slidably connected to the first guide rail 21 and the second guide rail 22. A blocking device 24 is disposed between the first guide rail 21 and the second guide rail 22 to block the replenishing tray 23. By setting the conveying module 20 to include the first guide rail 21 and the second guide rail 22 arranged in parallel, it is ensured that the replenishing tray 23 can slide smoothly in the horizontal direction, providing a stable guiding foundation for the replenishing process. The first guide rail 21 and the second guide rail 22 are parallel, so that the distance between the first guide rail 21 and the second guide rail 22 can be adjusted according to the different specifications of the replenishing tray 23, so as to achieve the adaptation of the replenishing tray 23 to the first guide rail 21 and the second guide rail 22, and ensure that the replenishing tray 23 moves smoothly and without obstruction. By setting a blocking device 24 between the first guide rail 21 and the second guide rail 22, the feeding tray 23 is fixed at the required position to prevent accidental movement caused by external force or inertia, ensuring accurate positioning during feeding. After feeding is completed, the blocking device 24 is released, allowing the feeding tray 23 to continue moving to the next working stage or return to the starting position to prepare for the next round of feeding, further improving the accurate positioning control of the automatic feeding mechanism.

[0047] Furthermore, the empty material detection module 30 is fixed on the frame 10 and positioned above the blocking device 24. The empty material detection module 30 is used to detect the missing material position of the replenishment tray 23. By positioning the empty material detection module 30 above the blocking device 24, an unobstructed full scan of the replenishment tray 23 is achieved, ensuring the accuracy and completeness of the detection. The empty material detection module 30 can capture image information of the replenishment tray 23 in real time and quickly identify which positions on the tray are lacking material through image processing algorithms, providing immediate feedback for subsequent replenishment actions, accurately locating the position information of each missing material, and ensuring that the replenishment module 50 performs precise replenishment.

[0048] Specifically, the feeding module 40 is fixed to the frame 10. The feeding module 40 includes a first feeding module 41 and a second feeding module 42. The first feeding module 41 is used to provide a first workpiece and includes a first vibrating plate 411. The second feeding module 42 is used to provide a second workpiece and includes a second vibrating plate 421. By setting the first feeding module 41 and the second feeding module 42, each dedicated to a specific workpiece, different production needs can be handled simultaneously, improving overall production flexibility and efficiency. The first vibrating plate 411 and the second vibrating plate 421 vibrate to arrange the workpiece along a predetermined track and move it towards the picking area, achieving continuity and uniformity in workpiece supply.

[0049] Furthermore, the replenishment module 50 is used to place the first workpiece on the first vibrating plate 411 or the second workpiece on the second vibrating plate 421 at the material shortage position of the replenishment plate 23. The replenishment module 50 includes a first pick-up nozzle 511 assembly 51 and a second pick-up nozzle 521 assembly 52. ​​The first pick-up nozzle 511 assembly 51 is used to pick up the first workpiece, and the second pick-up nozzle 521 assembly 52 is used to pick up the second workpiece. By setting the replenishment module 50 to place the first and second workpieces at the material shortage position of the replenishment plate 23, precise replenishment is achieved, the quality of finished products is improved, reliance on manual labor is reduced, insufficient or incorrect loading due to human negligence is avoided, and labor costs are saved.

[0050] As a further improvement to this utility model, please refer to Figure 2 The blocking device 24 includes a blocking cylinder 241 and a blocking member 242 connected to the blocking cylinder 241. The blocking cylinder 241 drives the blocking member 242 to prevent the feeding disc 23 from sliding. By setting the blocking device 24 to include a blocking cylinder 241 and a blocking member 242 connected to the blocking cylinder 241, when it is necessary to prevent the feeding disc 23 from sliding, the gas in the blocking cylinder 241 is pressurized, pushing the piston rod outward and driving the blocking member 242 to move to a predetermined position, thereby preventing the feeding disc 23 from sliding further along the guide rail. When feeding is completed and the feeding disc 23 needs to continue moving, the gas pressure in the blocking cylinder 241 is released, the piston rod retracts, and the blocking member 242 retracts accordingly, immediately releasing the restriction on the sliding of the feeding disc 23.

[0051] As a further improvement of this utility model, a positioning device 60 is also included. The positioning device 60 includes a positioning cylinder 61 and a positioning plate 62 connected to the positioning cylinder 61. The positioning cylinder 61 drives the positioning plate 62 to rise, and the positioning plate 62 fixes the feeding tray 23. The positioning cylinder 61 is connected to the blocking cylinder 241. By setting the positioning device 60 to include a positioning cylinder 61 and a positioning plate 62 connected to the positioning cylinder 61, the positioning cylinder 61 drives the positioning plate 62 to rise and contact the feeding tray 23, ensuring that the position of the feeding tray 23 remains fixed in subsequent operations, creating the necessary stability conditions for feeding or operation, and improving the stability of the automatic feeding mechanism.

[0052] As a further improvement to this utility model, please refer to Figure 3The replenishing module 50 further includes a replenishing body 53, a connecting plate 54, and a rotating body 55. The replenishing body 53 is fixed to the frame 10. One end of the connecting plate 54 is rotatably connected to the replenishing body 53, and the other end of the connecting plate 54 is rotatably connected to the rotating body 55. The end of the rotating body 55 away from the connecting plate 54 is connected to the first material suction nozzle 511 assembly 51 and the second material suction nozzle 521 assembly 52. ​​By configuring the replenishing module 50 to include the replenishing body 53, the connecting plate 54, and the rotating body 55, and by setting the replenishing body 53 to be fixed to the frame 10, and one end of the connecting plate 54 rotatably connected to the replenishing body 53, the replenishing module 50 further includes the replenishing body 53, the connecting plate 54, and the rotating body 55. The other end of the connecting plate 54 is rotatably connected to the rotating body 55. The end of the rotating body 55 away from the connecting plate 54 is connected to the first material suction nozzle 511 assembly 51 and the second material suction nozzle 521 assembly 52. ​​This increases the range of movement of the first material suction nozzle 511 assembly 51 and the second material suction nozzle 521 assembly 52 on the frame 10, ensuring that the feeding module 50 can move the workpiece at multiple angles and over a wide range. This avoids the problem that some workpieces cannot be moved due to angle limitations when feeding a large number of workpieces, and increases the accessibility and flexibility of the first material suction nozzle 511 assembly 51 and the second material suction nozzle 521 assembly 52 in space.

[0053] Furthermore, the rotating body 55 moves the first material-picking nozzle 511 assembly 51 through the connecting plate 54, placing the first workpiece on the first vibrating plate 411 at the material shortage position of the replenishing plate 23; the rotating body 55 moves the second material-picking nozzle 521 assembly 52 through the connecting plate 54, placing the second workpiece on the second vibrating plate 421 at the material shortage position of the replenishing plate 23. By setting the rotating body 55 to move the first material-picking nozzle 511 assembly 51 through the connecting plate 54, the first workpiece on the first vibrating plate 411 is placed at the material shortage position of the replenishment plate 23. This enables fine adjustments in multiple directions and angles, ensuring that the first material-picking nozzle 511 assembly 51 can accurately reach any specified material shortage position. Similarly, by setting the rotating body 55 to move the second material-picking nozzle 521 assembly 52 through the connecting plate 54, the second workpiece on the second vibrating plate 421 is placed at the material shortage position of the replenishment plate 23. This also enables fine adjustments in multiple directions and angles, ensuring that the second material-picking nozzle 521 assembly 52 can accurately reach any specified material shortage position. At the same time, the first material-picking nozzle 511 assembly 51 and the second material-picking nozzle 521 assembly 52 move the first and second workpieces respectively, significantly improving the replenishment efficiency. The two nozzle assemblies work synchronously, reducing idle time and machine waiting cycles, making the production line replenishment process smoother and more continuous.

[0054] As a further improvement of this utility model, a movable connecting shaft 56 is movably connected to the end of the rotating body 55 away from the connecting plate 54. The bottom end of the movable connecting shaft 56 is connected to the first material-picking nozzle 511 assembly 51 and the second material-picking nozzle 521 assembly 52. ​​The movable connecting shaft 56 moves up and down along the rotating body 55 to move the first material-picking nozzle 511 assembly 51 and the second material-picking nozzle 521 assembly 52 along the Z-axis. By setting the movable connecting shaft 56 movably connected to the end of the rotating body 55 away from the connecting plate 54, and the bottom end of the movable connecting shaft 56 being connected to the first material-picking nozzle 511 assembly 51 and the second material-picking nozzle 521 assembly 52, and the movable connecting shaft 56 moving up and down along the rotating body 55 to move the first material-picking nozzle 511 assembly 51 and the second material-picking nozzle 521 assembly 52 along the Z-axis, the first material-picking nozzle 511 assembly 51 and the second material-picking nozzle 521 assembly 52 can drive the first workpiece and the second workpiece. The movement of the workpiece along the height direction enhances the flexibility of the first pick-up nozzle 511 assembly 51 and the second pick-up nozzle 521 assembly 52 when moving the workpiece, facilitating flexible movement during the workpiece replenishment process and further expanding the application range of the automatic cleaning mechanism. The first pick-up nozzle 511 assembly 51 and the second pick-up nozzle 521 assembly 52 can adapt to vibratory feeders of different heights or workpiece shortage positions. Even if there are height changes inside the vibratory feeder, precise alignment and placement can be achieved, greatly enhancing the operational flexibility of the automatic replenishment mechanism in three-dimensional space.

[0055] As a further improvement to this utility model, please refer to Figure 4The first feeding module 41 further includes a first positioning fixture 412 for placing the first workpiece connected to the first vibrating plate 411, and a first transfer component 413 for moving the first workpiece onto the first positioning fixture 412; the second feeding module 42 further includes a second positioning fixture 422 for placing the second workpiece connected to the second vibrating plate 421, and a second transfer component 423 for moving the second workpiece onto the second positioning fixture 422. By setting the first feeding module 41 to include the first positioning fixture 412 for placing the first workpiece connected to the first vibrating plate 411, and the second feeding module 42 to include the second positioning fixture 422 for placing the second workpiece connected to the second vibrating plate 421, and the second transfer component 423 for moving the second workpiece onto the second positioning fixture 422, the precise positioning of the workpiece before entering the transfer process is ensured, placement errors are reduced, and the accuracy of subsequent assembly and product consistency are improved. The first transfer component 413 and the second transfer component 423 work in parallel, which can process the first workpiece and the second workpiece at the same time, significantly speeding up the feeding speed and increasing the overall throughput of material replenishment. At the same time, the highly automated feeding process reduces the need for manual intervention, which not only reduces the burden on workers but also improves operational safety.

[0056] As a further improvement to this utility model, please refer to Figures 5-6 The first material-picking nozzle 511 assembly 51 includes a first material-picking nozzle 511, a suction tube 512, and a solenoid valve 513 for controlling the adsorption of the first material-picking nozzle 511; the second material-picking nozzle 521 assembly 52 includes a second material-picking nozzle 521, the suction tube 512, and a solenoid valve 513 for controlling the adsorption of the second material-picking nozzle 521. By setting the first material-picking nozzle 511 and the second material-picking nozzle 521 to directly contact and adsorb the workpiece, it is ensured that the workpiece is firmly grasped without causing damage to the workpiece surface. At the same time, the first material-picking nozzle 511 and the second material-picking nozzle 521 can be differentiated according to different workpieces to adapt to the characteristics of the first and second workpieces. The solenoid valve 513 controls the adsorption action to ensure the efficiency, accuracy, and flexibility of the material-picking process.

[0057] As a further improvement of this utility model, the straw 512 includes a cavity 5121 and an air pipe connector 5122 disposed on the cavity 5121. The cavity 5121 is provided with a vacuum air pipe 5123 passing through the cavity 5121. A first spring 5124 is provided between the cavity 5121 and the vacuum air pipe 5123.

A second spring 5125 is provided between the adapter and the first feeding nozzle 511 or the second feeding nozzle 521. By setting the first spring 5124, the stress at the connection between the suction tube 512 and the vacuum tube 5123 can be effectively absorbed, preventing loosening or leakage caused by mechanical vibration or sudden air pressure changes, and maintaining good airtight performance. The second spring 5125 provides appropriate rebound force to protect the connection between the first material suction nozzle 511 or the second material suction nozzle 521 and the adapter from impact damage, and also ensures appropriate pressure control when the first material suction nozzle 511 or the second material suction nozzle 521 contacts the workpiece, thus extending the overall service life of the automatic feeding mechanism.

[0058] As a further improvement of this utility model, the solenoid valve 513 includes a vacuum tube connection end 5131 and a gas tube connection end 5132. The vacuum tube connection end 5131 is connected to the vacuum tube connector, and the gas tube connection end 5132 is connected to the gas tube connector 5122. By setting the solenoid valve 513 to include a vacuum tube connection end 5131 and a gas tube connection end 5132, with the vacuum tube connection end 5131 connected to the vacuum tube connector and the gas tube connection end 5132 connected to the gas tube connector 5122, and designing the vacuum tube connection end 5131 and the gas tube connection end 5132 separately, the solenoid valve 513 can achieve rapid and precise gas path switching, accelerate the cycle of material suction and discharge, improve overall efficiency, and the independent connection design helps maintain the airtightness of the system, reducing the possibility of air leakage, thereby ensuring the stability and reliability of the adsorption and release process, and reducing the failure rate of the automatic feeding mechanism during the feeding process.

[0059] As a further improvement of this utility model, the empty material detection module 30 includes a CCD camera 31 and a light source 32 disposed below the CCD camera 31. By including a CCD camera 31 and a light source 32 disposed below the CCD camera 31 in the empty material detection module 30, the light source 32 located below the CCD camera 31 can provide uniform and sufficient light to the object being detected, eliminate shadows, enhance image contrast, and effectively improve the stability and reliability of empty material detection. At the same time, the light angle and intensity can be adjusted according to different detection requirements to achieve material replenishment for workpieces of various materials and colors, thus expanding the application range of the automatic material replenishment mechanism.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application.
