Description

Technical Field

[0001] This utility model relates to the field of bulk material feeding technology, specifically to an automatic material dispensing mechanism using a vibratory feeder. Background Technology

[0002] Material feeding often requires the use of a separation mechanism for material distribution. Currently, existing material distribution mechanisms require manual operation and have a low degree of automation, which increases the labor intensity and reduces the efficiency of the material distribution process. In addition, existing material distribution mechanisms are prone to jamming when discharging from the vibratory feeder, which can easily cause scratches to the product during the feeding process. Furthermore, the feeding speed is relatively low, which causes great inconvenience to users. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic material dispensing mechanism for a vibratory feeder, so as to solve the problems mentioned in the background art of the existing material dispensing technology, such as low working efficiency, easy jamming, scratching of materials, and low material feeding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic material dispensing mechanism for a vibratory feeder, comprising a frame, a receiving assembly connected to the surface of the frame for receiving material from the vibratory feeder; a dispensing assembly disposed on the surface of the frame and on one side of the receiving assembly for dispensing material after it has been received by the receiving assembly; the dispensing assembly consists of a servo motor, a ball screw, a nut block, and a dispensing plate; the servo motor is fixed to the surface of the frame; and a position sensing assembly is connected between the frame and the dispensing assembly for sensing the position of the dispensing assembly during its movement.

[0005] Preferably, a junction box and a vacuum generator are installed on one side of the frame. The junction box facilitates wiring, while the vacuum generator provides positive and negative pressure air sources for the material dispensing mechanism.

[0006] Preferably, a rotatable ball screw is mounted on the surface of the frame via a bearing seat, and the output end of the servo motor is fixedly connected to one end of the ball screw, with a nut block threaded onto the surface of the ball screw.

[0007] Preferably, a material distribution plate is slidably connected to the surface of the frame, and at least two material distribution grooves are formed on the surface of the material distribution plate; a sliding groove is formed on the surface of the frame, and the top of the nut block passes through the sliding groove and is fixedly connected to the surface of the material distribution plate.

[0008] Preferably, the receiving assembly includes a receiving suction cup, a pressure plate, a bracket, and an optical fiber sensor. The surface of the frame is fixed with a receiving suction cup having a receiving groove. The receiving suction cup is connected to a vacuum generator, and a pressure plate is installed on the receiving groove of the receiving suction cup.

[0009] Preferably, the surface of the receiving suction cup is fixed with a bracket by bolts, and an optical fiber sensor is installed at the top of the bracket. The optical fiber sensor is used to sense the position of the dispensing trough.

[0010] Preferably, the positioning sensing component consists of a support plate, a photoelectric sensor, and a sensing sheet. The support plate is fixed to the surface of the frame, and the photoelectric sensor is installed on the surface of the support plate. The sensing sheet is fixed to the surface of the dispensing plate, and the sensing sheet and the photoelectric sensor work together to sense the travel of the dispensing plate.

[0011] Compared with existing technologies, the advantages of this invention are as follows: When the automatic dispensing mechanism of this vibratory feeder is implemented, the products will sequentially enter one of the dispensing slots on the dispensing plate. Then, the ball screw is driven by a servo motor to rotate. The rotation of the ball screw will engage with the threaded nut block to move the dispensing plate. When the fiber optic sensor on the support surface detects that the next dispensing slot on the surface of the dispensing plate has moved into place, the product will accurately enter the next dispensing slot for dispensing again. This process is repeated multiple times to complete the dispensing work. The support plate and the receiving slot of the receiving suction cup of this invention are both made of hard anodized aluminum, which protects the product from scratches and increases wear resistance. At the same time, the cooperation between the receiving suction cup and the vacuum generator can make the bottom of the product be vacuumed during dispensing. With the sensing of the fiber optic sensor, it can block products in front and behind to ensure that they do not interfere with the dispensing. This invention uses a servo motor and ball screw, which makes the structure compact and highly accurate. Moreover, the mechanism is modularly designed, making assembly and maintenance convenient.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] The structure of the vibratory feeder automatic dispensing mechanism provided by this utility model is as follows: Figure 1 as well as Figure 3 As shown, the device includes a frame 1, with a receiving assembly 2 connected to the surface of the frame 1. The receiving assembly 2 is used for receiving materials discharged from the vibratory feeder. A junction box 11 and a vacuum generator 12 are installed on one side of the frame 1. The junction box 11 facilitates wiring, while the vacuum generator 12 provides positive and negative pressure air sources for the dispensing mechanism. The receiving assembly 2 includes a receiving suction cup 21, a pressure plate 22, a bracket 23, and a fiber optic sensor 24. The receiving suction cup 21 with a receiving groove is fixed to the surface of the frame 1. The receiving suction cup 21 is connected to the vacuum generator 12. The pressure plate 22 is installed on the receiving groove of the receiving suction cup 21. The bracket 23 is fixed to the surface of the receiving suction cup 21 by bolts, and the fiber optic sensor 24 is installed on the top of the bracket 23. The fiber optic sensor 24 is used to sense the position of the dispensing groove 341.

[0020] During implementation, the vibratory feeder utilizes the product characteristics to arrange the products in an orderly manner, and the products enter the receiving groove of the receiving suction cup 21.

[0021] Furthermore, such as Figure 2 as well as Figure 4As shown, a material distribution component 3 is provided on the surface of the frame 1 and on one side of the receiving component 2. The material distribution component 3 is used for distributing materials after receiving them from the receiving component 2. The material distribution component 3 consists of a servo motor 31, a ball screw 32, a nut block 33, and a material distribution plate 34. The servo motor 31 is fixedly connected to the surface of the frame 1. The surface of the frame 1 is equipped with a rotatable ball screw 32 through a bearing seat. The output end of the servo motor 31 is fixedly connected to one end of the ball screw 32. The surface of the ball screw 32 is threadedly connected to the nut block 33. The surface of the frame 1 is slidably connected to the material distribution plate 34. The surface of the material distribution plate 34 has at least two material distribution grooves 341. The surface of the frame 1 has a sliding groove 13. The top of the nut block 33 passes through the sliding groove 13 and is fixedly connected to the surface of the material distribution plate 34.

[0022] During implementation, the product will sequentially enter a distribution slot 341 of the distribution plate 34. Then, the ball screw 32 will be driven to rotate by the servo motor 31. The rotation of the ball screw 32 will engage with the nut block 33 to move the distribution plate 34. When the fiber optic sensor 24 on the surface of the bracket 23 detects that the next distribution slot 341 on the surface of the distribution plate 34 has moved into place, the product will accurately enter the next distribution slot 341 for further distribution. This process is repeated multiple times to complete the distribution work.

[0023] Furthermore, such as Figure 3 as well as Figure 4 As shown, a positioning sensing component 4 is connected between the frame 1 and the material distribution component 3. The positioning sensing component 4 is used for positioning sensing when the material distribution component 3 moves. The positioning sensing component 4 consists of a support plate 41, a photoelectric sensor 42, and a sensing plate 43. The support plate 41 is fixed to the surface of the frame 1, and the photoelectric sensor 42 is installed on the surface of the support plate 41. The sensing plate 43 is fixed to the surface of the material distribution plate 34, and the sensing plate 43 and the photoelectric sensor 42 cooperate to sense the stroke of the material distribution plate 34.

[0024] In practice, the position sensing of the stroke is achieved by the photoelectric sensor 42 on the surface of the support plate 41 working in conjunction with the sensing sheet 43.

[0025] Working principle: such as Figure 5As shown, during use, the vibratory feeder utilizes the product characteristics to arrange the products in an orderly manner. The products enter the receiving groove of the receiving suction cup 21. During distribution, the products will sequentially enter one of the distribution grooves 341 of the distribution plate 34. Subsequently, the servo motor 31 drives the ball screw 32 to rotate. The rotation of the ball screw 32 will engage with the nut block 33 to move the distribution plate 34. When the distribution plate 34 moves, it is sensed by the position sensing component 4. During sensing, the photoelectric sensor 42 on the surface of the support plate 41 cooperates with the sensing plate 43 to realize the position sensing of the stroke. When the fiber optic sensor 24 on the surface of the bracket 23 detects that the next distribution groove 341 on the surface of the distribution plate 34 has moved into position, the product will accurately enter the next distribution groove 341 for distribution again. This process is repeated multiple times to complete the distribution work.

[0026] The support plate 41 and the receiving groove of the receiving suction cup 21 of this utility model are both made of hard anodized aluminum, which protects the product from scratches and increases wear resistance. At the same time, the cooperation between the receiving suction cup 21 and the vacuum generator 12 can make the bottom of the product be vacuumed during the dispensing process. With the sensing of the fiber optic sensor 24, it can block the products in front and behind, ensuring that the dispensing is not interfered with. This utility model uses a servo motor 31 and a ball screw 32 to make the structure compact and highly accurate. Moreover, the mechanism is modular, making it easy to assemble and maintain.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
