[0002] Metal powder injection molding is a high-tech process that combines traditional powder metallurgy with plastic injection molding, representing a revolution in the forming of small, complex parts.

The resulting blank is degreased and then sintered to densify into the finished product. Post-processing can also be performed if necessary.

[0003] Previously, the weighing and batching of raw materials for MIM parts was done manually. Employees had to pour the raw materials into containers according to the batching list, and then adjust the batching according to the reading of the electronic scale. The above actions had to be repeated according to the batching list. The disadvantages of this batching method were that the labor intensity of employees was high, the instability was high, errors were easy to occur, and the production efficiency was low.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-2 The diagram illustrates a production line for automatic weighing and batching of raw materials for MIM (Metal Injection Molding) parts. It includes a frame 1 and a horizontal traversing mechanism 2 mounted on the frame. Multiple feeding stations are arranged in parallel along the transmission direction of the horizontal traversing mechanism 2, each equipped with a sensor. The horizontal traversing mechanism includes a moving platform 3, on which a printer 5 and an electronic scale 6 are mounted. Each feeding station is equipped with a hopper 15, a coarse feeding component 17, and a fine feeding component 18. The feeding switches are controlled by a PLC. The moving platform sequentially passes through each feeding station to complete feeding, weighing, and label printing, ensuring accurate feeding and real-time traceability of the weight of each batch.

[0023] Specifically, the material feeding stations include granule feeding station 7, powder feeding station 8, and adhesive feeding station 9. The number of granule feeding station 7 and powder feeding station 8 can be adjusted according to the production needs of different raw materials.

[0024] like Figure 3 and Figure 4 As shown, specifically, the pellet feeding station includes a feeder 14 for replenishing the hopper and an auxiliary material cup component 16. The coarse feeding component of the pellet feeding station includes a coarse feeding screw 23 located below the hopper. The coarse feeding screw 23 is arranged horizontally and has a coupling 22 and a drive servo motor 21 at one end, and a coarse feeding outlet at the other end.

[0025] like Figure 5As shown, specifically, the fine feeding component of the pellet feeding station is located on the side of the coarse feeding outlet, including a longitudinally arranged stepper motor 24, a stepper reducer, a bearing seat 26, and a storage tank 29. The stepper reducer is connected to a spiral stirring blade 28 located in the storage tank via a coupling 25 and a rotating shaft 27. The lower part of the spiral stirring blade is provided with a storage discharge port 30, a fine feeding screw 31, and a fine feeding sealing component 32.

[0026] like Figure 6 As shown, specifically, the glue feeding station includes a glue vacuum preparation unit 33, which is connected to a high-flow glue feeding component 36 via a high-flow glue feeding linear module 34, and a precision glue feeding component 37 via a precision glue feeding linear module 35.

[0027] Specifically, the sensors include station container sensors 10 installed at each workstation, and station position sensors 13 installed on the horizontal traversing mechanism. The sensors at each workstation cooperate to send position signals to the PLC, enabling subsequent production processes.

[0028] Specifically, the horizontal traversing mechanism includes a linear guide rail and a rack arranged on the frame. A traversing platform is mounted on the linear guide rail, and a servo motor 12 is mounted on the traversing platform. A gear connected to the bottom of the servo motor meshes with the rack. When the motor starts, it drives the gear to rotate, moving it along the rack direction and causing the traversing platform to move along the guide rail.

[0029] The entire equipment workflow is as follows: Employees set the required ingredient list; the PLC sets the feeding process based on the list; employees place containers on the weighing platform; the weighing platform moves to the granule feeding station, triggering the container sensor; the coarse-processing sealing component opens, and feeding begins; the electronic scale sends a reading to the host computer, which transmits the data to the PLC; the PLC controls the coarse-processing speed to reach the specified range, and the coarse-processing sealing component closes; the weighing platform moves to the fine-processing station; the fine-processing sealing component opens, and feeding begins; the electronic scale sends a reading to the host computer, which transmits the data to the PLC; the PLC controls the fine-processing speed to reach the specified range, and the fine-processing sealing component closes. The host computer records the readings, and a coding machine records the granule-related data. Employees remove the container and coding label from the next station. The weighing platform moves to the next station for feeding until the batching is complete.
