Description

Technical Field

[0001] This utility model belongs to the field of injection molding equipment technology, specifically relating to an automatic loading and unloading device for embedded injection molding magnetic parts. Background Technology

[0002] With the development of automotive intelligence, the application of automotive position sensors is becoming increasingly widespread. However, the introduction of these sensors can, to some extent, detract from the overall aesthetics of the vehicle. Therefore, the process of injection molding the magnetic components used to manufacture these sensors has emerged. The magnetic sensor components are embedded within the injection-molded parts, meeting the requirements for stable assembly and improved appearance. However, during the injection molding process, the loading and unloading of these magnetic components presents a significant challenge. Due to their small size, the alignment accuracy required when placing them into the injection mold is very high. Ordinary loading equipment, such as screw conveyors and vibrating hoppers, cannot meet these precise loading requirements. In the unloading stage, the existing process involves unloading the injection-molded magnetic component and the gate as a whole, collecting the material, and then cutting off the gate material. This leads to reduced production efficiency and is prone to errors during operation. Therefore, improvements to the existing equipment are necessary. Summary of the Invention

[0003] To address the aforementioned problems and technical needs, this utility model provides an automatic loading and unloading device for embedded injection molded magnetic parts. This device can automatically load magnetic parts, automatically clamp the injection molded products after injection molding, automatically remove the gates of the injection molded products, and classify and collect the gates and injection molded products. It has the advantages of stable operation, high processing accuracy, and low operation difficulty.

[0004] The technical solution of this utility model is as follows: An automatic loading and unloading device for embedded injection-molded magnetic parts includes a loading and unloading platform, a six-axis robot, an injection mold, and a molding device. The six-axis robot is positioned between the loading and unloading platform and the molding device. A turntable is provided on the molding device platform, and the injection mold is mounted on the turntable. The loading and unloading platform is equipped with a magnetic part sorting mechanism and a gate removal mechanism. The magnetic part sorting mechanism arranges the magnetic parts in batches and rows. A clamping assembly is installed at the end of the six-axis robot. The clamping assembly is used to clamp a row of magnetic parts, load the magnetic parts into the injection mold, and remove the injection-molded product from the injection mold. The gate removal mechanism is located on the movement path of the six-axis robot and is used to cut off the gate of the injection-molded product.

[0005] Furthermore, the gate removal mechanism includes a barrier operation chamber, a material discharge slide, and an ultrasonic mold. The barrier operation chamber is set on the machine platform, and the material discharge slide is fixedly installed inside the barrier operation chamber. The front end of the material discharge slide extends outward from the window on the front side of the barrier. A vertical cylinder is installed at the bottom of the barrier operation chamber. The top of the vertical cylinder passes through the material discharge slide and connects to the ultrasonic mold. The vertical cylinder drives the ultrasonic mold to move up and down above the material discharge slide. The top of the ultrasonic mold is provided with a workpiece groove corresponding to the injection molded product. The clamping assembly clamps the gate of the injection molded product and places the injection molded products one by one into the workpiece groove of the ultrasonic mold. The ultrasonic waves generated by the ultrasonic mold automatically cut off the connection between the gate and the injection molded product. The injection molded product slides down along the workpiece groove and the material discharge slide.

[0006] Furthermore, the bottom of the gate removal mechanism is equipped with a conveyor belt, and the injection molded product slides down from the unloading slide onto the conveyor belt and is conveyed forward; a first fan is provided on the unloading slide, and the first fan is fixedly installed behind the ultrasonic mold through sheet metal parts. The first fan blows towards the ultrasonic mold, and a second fan is provided below the unloading slide, which blows horizontally towards the end of the unloading slide.

[0007] Furthermore, the magnetic component sorting mechanism includes a back plate, a feeding cylinder, a magnetic component clip assembly, a sorting plate, and a top-loading cylinder. Side plate supports are symmetrically connected to both sides of the back plate, and a transverse sorting plate is connected between the two side plate supports. The sorting plate has a row of loading holes, and a top-loading cylinder is connected to the bottom of each loading hole. A row of magnetic component clip assemblies is provided behind the loading holes, and the magnetic component clip assemblies correspond one-to-one with the loading holes. Each magnetic component clip assembly is connected to the back plate through a feeding cylinder. The magnetic component clip assembly is filled with multiple magnetic components. The feeding cylinder drives the magnetic component clip assembly to slide forward, and the magnetic component clip assembly fills the magnetic components into the loading holes. The top-loading cylinder pushes the upper end of the magnetic component out of the loading hole.

[0008] Furthermore, the magnetic component clip assembly includes a slider, a cylindrical clip, and a sensor. A row of grooves is provided on the distribution plate behind the loading hole, with a slider connected to each groove. Each slider has a through hole corresponding to the loading hole. The slider slides back and forth, aligned with the loading hole. The top of the slider is connected to the cylindrical clip, which is filled with a magnetic component. As the slider slides forward, the through hole aligns with the loading hole, allowing the magnetic component in the cylindrical clip to fall into the loading hole. The cylindrical clip is equipped with a sensor that detects the falling magnetic component. The sensor prevents missed magnetic components, automates the detection of the magnetic component filling status, and improves operational stability.

[0009] Furthermore, the fixture assembly includes a connecting plate, a loading magnetic nozzle, and a unloading gripper. The connecting plate is rotatably connected to the end of the six-axis robot at its center. A row of loading magnetic nozzles and a row of unloading grippers are respectively connected to both ends of the connecting plate. The loading magnetic nozzles attract magnetic components from the loading holes and place the magnetic components into the injection mold. The unloading grippers pick up the gate of the injection molded product and transfer the injection molded product and the gate together to the gate removal mechanism. By setting two sets of grippers on the fixture assembly, which can perform loading and unloading operations respectively, a single movement of the six-axis robot can complete the process of picking up material from the injection mold and placing new material, reducing the waiting time of the injection mold, accelerating the processing rhythm of the injection mold, and improving work efficiency.

[0010] Furthermore, the loading and unloading machine is provided with a gate discharge port in the middle, and a waste material slide is provided inside the gate discharge port. The cut-off gate slides down the machine through the waste material slide.

[0011] Furthermore, an operating platform is provided at the end of the conveyor belt, and the injection-molded products are pushed onto the operating platform by the conveyor belt. The injection-molded products are collected and sorted manually at the operating platform and then removed from the machine table.

[0012] The beneficial effects of this utility model are as follows: 1) This equipment can automatically load, unload, remove and discard gates from injection molds without human intervention. The robotic arm operates automatically with high positioning accuracy, avoiding missing or incorrect magnetic parts, reducing the workload of operators, and significantly improving the quality of injection molded products; 2) The robotic arm's operation is more energy-efficient. The gripping component at the end of the robotic arm is equipped with a row of loading magnetic nozzles and a row of unloading grippers, which are used for loading magnetic parts and unloading injection molded parts, respectively. Before loading the injection mold, the already processed injection molded products can be removed first, and then the magnetic parts can be placed in. After removing and discarding the gates, the next batch of magnetic parts can be quickly gripped. The loading and unloading actions are simple and efficient, avoiding excessive movement per unit time. The predetermined actions are completed quickly with small movements, reducing the difficulty of operating the robotic arm and further improving processing efficiency. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] As shown in the figure, this utility model's automatic loading and unloading equipment for embedded injection molded magnetic parts includes a loading and unloading machine 1, a six-axis robot 2, an injection mold 3, and a molding device 4. The six-axis robot 2 is positioned between the loading and unloading machine 1 and the molding device 4.

The loading and unloading machine 1 is equipped with a magnetic part sorting mechanism 5 and a gate removal mechanism 7. The magnetic part sorting mechanism 5 arranges the magnetic parts 57 in batches and rows. The end of the six-axis robot 2 is equipped with a clamping assembly 6. The clamping assembly 6 automatically clamps a row of magnetic parts 57 and moves them above the injection mold 3. When the injection mold 3 opens and ejects the injection molded product 31, the clamping assembly 6 first performs a material removal operation on the injection molded product 31, and then loads the magnetic parts 57 into the injection mold 3. The six-axis robot 2 drives the clamping assembly 6 to move onto the gate removal mechanism 7, which automatically removes the gate from the injection molded product 31.

[0016] The magnetic component sorting mechanism 5 includes a back plate 51, a feeding cylinder 52, a magnetic component clip assembly 53, a sorting plate 54, and a top-loading cylinder 55.

Each magnetic component clip assembly 53 and back plate 51 are connected by a feeding cylinder 52. Multiple magnetic components 57 are filled in the magnetic component clip assembly 53. The feeding cylinder 52 drives the magnetic component clip assembly 53 to slide forward. The magnetic component clip assembly 53 fills the magnetic component 57 into the loading hole 541. The ejecting cylinder 55 ejects the upper end of the magnetic component 57 out of the loading hole 541. The magnetic clip assembly 53 includes a slider 531, a cylindrical clip 532, and a sensor 533. A row of grooves 542 is provided on the distribution plate 54 behind the loading hole 541. A slider 531 is connected to each groove 542. The slider 531 has a through hole corresponding to the loading hole 541. The slider 531 slides back and forth aligned with the loading hole 541. The top of the slider 531 is connected to the cylindrical clip 532, which is filled with a magnetic component 57. The slider 531 slides forward so that the through hole is aligned with the loading hole 541, and the magnetic component 57 in the cylindrical clip 532 falls into the loading hole 541. The cylindrical clip 532 is provided with a sensor 533, which can sense the falling of the magnetic component 57.

[0017] The gate removal mechanism 7 includes a barrier operation chamber 71, a material discharge slide plate 72, and an ultrasonic mold 73. The barrier operation chamber 71 is set on the machine table. The material discharge slide plate 72 is fixedly installed inside the barrier operation chamber 71. The front end of the material discharge slide plate 72 extends outward from the window on the front side of the barrier. A vertical cylinder 74 is installed at the bottom of the barrier operation chamber. The top of the vertical cylinder 74 passes through the material discharge slide plate 72 and connects to the ultrasonic mold 73. The vertical cylinder 74 drives the ultrasonic mold 73 to move up and down above the material discharge slide plate 72. The top of the ultrasonic mold 73 is provided with a workpiece groove 731 corresponding to the injection molded product 31. The clamping assembly 6 clamps the gate of the injection molded product 31 and places the injection molded product 31 into the workpiece groove 731 of the ultrasonic mold 73 one by one. The ultrasonic waves generated by the ultrasonic mold 73 automatically cut off the connection between the gate and the injection molded product. The injection molded product 31 slides down along the workpiece groove 731 and the material discharge slide plate 72. The gate removal mechanism 7 has a conveyor belt 77 at its bottom. The injection molded product 31 slides down from the discharge slide plate 72 onto the conveyor belt 77 and is conveyed forward. A first fan 75 is installed on the discharge slide plate 72. The first fan 75 is fixedly installed behind the ultrasonic mold 73 by sheet metal parts. The first fan 75 blows air towards the ultrasonic mold 73. A second fan 76 is installed below the discharge slide plate 72. The second fan 76 blows air laterally towards the end of the discharge slide plate 72. An operating table 13 is installed at the end of the conveyor belt 77. The injection molded product 31 is pushed onto the operating table 13 by the conveyor belt 77.

[0018] The clamping assembly 6 includes a connecting plate 61, a feeding magnetic nozzle 62, and a discharging gripper 63. The middle part of the connecting plate 61 is rotatably connected to the end of the six-axis robot 2. A row of feeding magnetic nozzles 62 and a row of discharging grippers 63 are respectively connected to both ends of the connecting plate 61. The feeding magnetic nozzles 62 attract the magnetic component 57 in the feeding hole 541 and put the magnetic component 57 into the injection mold 3. The discharging grippers 63 clamp the gate of the injection molded product 31 and transfer the injection molded product 31 and the gate together to the gate removal mechanism 7.

[0019] The loading and unloading machine 1 is provided with a gate discharge port 11 in the middle, and a waste material slide 12 is provided inside the gate discharge port 11. The cut gate slides down the machine through the waste material slide 12.

[0020] The operation process of this utility model: The magnetic component sorting mechanism 5 feeds materials into the loading hole 541. The feeding cylinder 52 pushes the slider 531 forward, so that the cylindrical spring clip 532 is aligned with the loading hole 541. A magnetic component 57 falls from the cylindrical spring clip 532 and is filled into the corresponding loading hole 541. After the sensor 533 on the cylindrical spring clip 532 senses that the magnetic component 57 has fallen, the feeding cylinder 52 retracts and the top material cylinder 55 starts to push the magnetic component 57 upward. The upper end of the magnetic component 57 protrudes out of the loading hole 541, which is convenient for the clamping component 6 to perform clamping operation. The feeding magnetic nozzle 62 of the clamping component 6 clamps the feeding material. The bottom end of the feeding magnetic nozzle 62 corresponds to the magnetic part 57 exposed in the feeding hole 541. Then the six-axis robot 2 drives the clamping component 6 to move above the turntable 41 of the molding equipment 4. The injection mold 3, which has completed injection and mold opening, rotates to be close to the clamping component 6 via the turntable 41. The clamping component 6 first unloads the material, then loads it. The clamping component 6 rotates a row of unloading jaws 63 to align with the injection molded product 31. The unloading jaws 63 clamp the gate of the injection molded product 31 and remove the injection molded product 31 and the gate together from the injection mold 3. Then, the loading magnetic nozzle 62 is rotated to align with the injection mold 3 and the attracted magnetic part 57 is placed into the injection mold 3. The injection mold 3 then performs injection molding again. The gate is cut off and the material is separated. The clamping component 6 moves the injection molded product with the gate to the ultrasonic mold 73. The unloading claw 63 keeps the clamping state. The injection molded product 31 is placed into the workpiece groove 731 of the ultrasonic mold 73. The ultrasonic wave generates ultrasonic vibration to separate the injection molded product 31 from the gate. After the injection molded product is released, it slides from the workpiece groove 731 into the unloading slide plate 72 and then slides down onto the conveyor belt 77. Two fans blow cold air at the same time to help cool the injection molded product 31 and provide power for the smooth sliding of the injection molded product. The gate is discarded. The gate that has completed automatic separation is still held by the unloading claw 63. The gripping component 6 moves the gate above the gate discard port 11 and releases it. The gate slides down the machine table along the discard slide 12. Then the gripping component 6, which is in an empty state, moves again to the magnetic part distribution mechanism 5 to carry out the next round of material picking operation.
