Description

Technical Field

[0001] This utility model relates to the field of magnetic material forming and processing technology, and in particular to a dual-station magnetic powder forming loading and unloading device. Background Technology

[0002] In the production of magnetic materials, one process involves initially extruding the magnetic powder material into shape. After extrusion, subsequent processes are carried out to further process it into magnetic material products used in various mechanical and electronic products.

[0003] Currently, some factories' magnetic powder material forming processing equipment is equipped with an extrusion molding machine. The extrusion molding machine contains a forming mold. After the magnetic powder is weighed, the operator pours the weighed powder into the forming mold inside the extrusion molding machine. After extrusion molding is completed, the product is ejected from the mold. At this point, the operator removes the molded product from the mold, inspects its appearance, and initially classifies the products into good and defective products. Good products are packed into packaging bags, which are then placed in a vacuum sealer for vacuuming. After vacuuming, the packaging bags are placed in a product placement box. Once the product placement box is full, the products are moved to subsequent processing stations for further processing. Defective products are placed in a collection box for centralized disposal. This process is repeated to complete the magnetic powder extrusion molding work.

[0004] In this magnetic powder molding process, because the magnetic powder material is easily oxidized and is in powder form, the machine is equipped with a protective cover. This cover is sealed and filled with nitrogen, creating a nitrogen-filled workspace. Operators wear gloves attached to the protective cover and operate the machine through observation windows. The process involves numerous delicate movements and prolonged repetitive tasks, resulting in high labor intensity and fatigue, which negatively impacts operator efficiency. Furthermore, the requirement of one operator per extrusion molding machine increases labor costs and consequently, production costs. Summary of the Invention

The rodless cylinder 302 drives the weighing hopper 311 to the end of the linear feeding trough 202. The vibrator 203 starts vibrating and feeding, and the magnetic powder falls into the weighing hopper 311 along the linear feeding trough 202. When the weighing device 310 reaches the set value, the magnetic powder hopper 11 stops feeding, the linear feeding trough 202 stops feeding, and the rodless cylinder 302 drives the discharge funnel 305 to the discharge port of the forming mold 901 in the extrusion molding machine 9. The tilting cylinder 307 tilts the hopper 311 90°, changing the weighing hopper 311 from a horizontal to a vertical state.

[0048] This device is a dual-station extrusion molding unit, with two sets of extrusion molding machines 9 operating alternately, and robotic arm gripping devices 5 alternately picking up materials. This section details the production process using one set of extrusion molding machines 9. The magnetic powder hopper 11 is activated, and the magnetic powder within falls into the linear feeding trough 202 on the linear vibrating feeding device 2. The vibrator 203 is activated, feeding the magnetic powder to the outlet end of the linear feeding trough 202. Simultaneously, the rodless cylinder 302 drives the weighing hopper 311 to the feeding end of the linear feeding trough 202, and the magnetic powder falls into the weighing hopper 311 along the linear feeding trough 202. When the weighing device 310 is about to reach the set value, the output shaft of the second lifting cylinder 402 extends, the baffle plate 403 descends, and the comb teeth 40... 31 blocks the amount of magnetic powder falling, allowing only a small amount to enter the weighing hopper 311 for accurate weighing. When the weighing device 310 reaches the set value, the magnetic powder hopper 11 stops feeding, the linear feed chute 202 stops feeding, and the rodless cylinder 302 drives the discharge funnel 305 to the discharge port of the forming mold 901 in the extrusion molding machine 9. The tilting cylinder 307 tilts the hopper 311 90°, changing it from a horizontal to a vertical position. The magnetic powder in the weighing hopper 311 is poured into the discharge funnel 305, and then enters the forming mold 901. The first vibrator 306 and the second vibrator 312 are activated. The second vibrator 312 ensures that all the magnetic powder adhering to the inner wall of the weighing hopper 311 enters the discharge funnel 305, while the first vibrator 306 ensures that all the magnetic powder adhering to the discharge funnel 305 enters the forming mold 901. The rodless cylinder 302 drives the weighing hopper 311 back to the feeding end of the linear feeding trough 202 for another magnetic powder weighing and receiving. The extrusion molding machine 9 performs the extrusion molding operation. After the extrusion molding operation is completed, the molded product is ejected, the robotic arm 501 starts, and the gripper 504 takes the molded product out of the extrusion molding machine 9. It passes through the material detection device 7, where the sensor 703 detects that the gripper 504 is holding the molded product. The gripper 504 continues to hold the molded product to the vision detection device 8, where the camera assembly 807 detects the appearance and dimensions of the molded product. At the same time, the linear motion platform 601 drives the carrier 603 to the material placement position of the gripper 504. If the molded product is a good product, the robotic arm 501 drives the gripper 504 to place it into the carrier 603. If the molded product is a defective product, the robotic arm 501 drives the gripper 504 to place it into the defective product box 604.Another set of extrusion molding machines 9 performs extrusion molding operations simultaneously. The robotic arm gripper device 5 alternately picks up and releases materials. When the carrier 603 is full of molded products, the operator removes the carrier 603 and the products placed on it together, puts them into a packaging bag, and puts the packaging bag into the vacuum machine 10 to complete the vacuuming operation. At the same time, the output shaft of the third lifting cylinder 1602 extends, and the lifting plate 1603 seals against the inner side wall of the top wall of the material picking bin 1601. The material box 1604 is lifted to the material discharging position, and the operator puts the vacuumed products into the material box 1604. 4. When the material bin 1604 is full, the output shaft of the third lifting cylinder 1602 retracts, the top plate 1606 seals against the outer wall of the top of the material receiving bin 1601, the material bin 1604 enters the material receiving bin 1601, the material receiving bin door 1607 opens, the operator takes out the material bin 1604, then puts in an empty material bin 1604, closes the material receiving bin door 1607, the output shaft of the third lifting cylinder 1602 pushes out, the lifting plate 1603 seals against the inner wall of the top of the material receiving bin 1601, the material bin 1604 is lifted to the discharge position, and materials continue to be placed. This cycle continues, and the operator only needs to vacuum-pack the carrier 603 and the molded products on it and put them into the material bin, reducing delicate movements, greatly reducing labor intensity, improving production efficiency, and reducing production costs.
