For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 7 shown, the automatic weighing and sorting device of this embodiment includes: a feeding mechanism 1, a weighing mechanism 2, and a discharging mechanism 3. The feeding mechanism 1 is arranged on one side of the weighing mechanism 2, and the discharging mechanism 3 is arranged on the other side of the weighing mechanism 2. The weighing mechanism 2 includes a weighing frame 21, a weighing guide rail 22 arranged on the weighing frame 21, a weighing drive belt 23 arranged on the weighing guide rail 22, and a weighing system. The discharging mechanism 3 includes a receiving component 31, a lifting component 32, a defective product receiving tray 33, and a non-defective product receiving tray 34. The lifting component 32 includes a lifting frame 321, a guide post 322 arranged on the lifting frame 321, a transfer disk 323 slidably engaged with the guide post 322, and a lifting lead screw structure 324 connected to the transfer disk 323. A transfer drive structure 325 is arranged on the transfer disk 323. By driving the weighing drive belt 23 to rotate through a motor, the materials placed on the weighing drive belt 23 are conveyed. The weighing adopts overall weighing, and the layout of the weighing structure is a conventional design in the art. The strain gauge in the weighing system is placed under the weighing frame 21, and the weighing of the materials is realized by weighing the entire weighing frame 21.

[0024] The weighing rail 22 is slidably mounted on the weighing frame 21 through a sliding column 24. A distance adjustment screw structure 25 is provided on the weighing frame 21, and the distance adjustment screw structure 25 is connected to the weighing rail 22. The distance between the weighing rails 22 can be driven by the distance adjustment screw structure 25, so that the weighing and sorting of materials of different sizes can be realized, and the adaptability is good. In order to facilitate the operation, the weighing mechanism 2 also includes a control screen 20, which can be used to adjust the equipment running speed, input material information, observe the weight and perform data statistics. The control screen 20 here can also be set at other locations, or a separate frame can be set for installation.

[0025] The feeding mechanism 1 includes a feeding frame 11, a feeding conveyor belt 12 arranged on the feeding frame 11, and a suction component 13 arranged above the feeding conveyor belt 12. The suction component 13 is used to convey the material from the feeding conveyor belt 12 to the weighing mechanism 2. The material is fed by suction without damaging the material. The feeding mechanism 1 may not be provided here, and a mechanical arm may be directly used for feeding.

[0026] The suction assembly 13 includes a mounting plate 131 with a guide rail and an actuator plate 132 slidably matched with the guide rail. A synchronous belt 133 is arranged on the actuator plate 132. A lifting cylinder 134 is arranged at the lower part of the actuator plate 132. A suction head 135 is arranged at the output end of the lifting cylinder 134.

[0027] When in use, the material is loaded manually or by a robotic arm and sent to the loading conveyor belt 12. The suction head 135 is driven downward by the lifting cylinder 134 to make it contact with the material. The material is sucked by the suction head 135, and then the actuator plate 132 is driven to move by the synchronous belt 133 to transport the material to the weighing rail 22. The weighing system will weigh the material and input the weighing result into the controller. The controller gives the next execution command. If the current weighing structure is qualified, the material is transported to the good product receiving tray 34 through the unloading mechanism 3. If the current weighing structure is unqualified, the material is transported to the defective product receiving tray 33 through the unloading mechanism 3. The specific process of the unloading mechanism 3 is that the lifting screw structure 324 drives the transfer plate 323 to rise and fall, and the transfer drive structure 325 on the transfer plate 323 pushes the material to the defective receiving plate 33 or the good receiving plate 34. The receiving component 31 is used to receive the material conveyed by the weighing drive belt 23 during the process. The conveying rate can be adjusted according to the rate of the lifting screw structure 324 to avoid abnormal operation.

[0028] The above are only the embodiments of the present utility model, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
