Description

Technical Field

[0001] This utility model relates to the field of material feeding device technology, specifically a material feeding device for continuous production of multiple injection molding processes. Background Technology

[0002] Existing injection molding feeding and conveying devices are mostly laid out in a straight line, with each processing mechanism arranged sequentially on both sides of the feeding and conveying device. While this makes the production line operation process more intuitive, for products that require multiple injection molding processes to achieve molding, the number of injection molding mechanisms is large and the production line is long. This reduces the intuitiveness of the production line structure, occupies more space, increases the cost of the conveying device, and during the production process, semi-finished products are prone to accumulate on the conveying device, causing subsequent production processes to stagnate and reducing production efficiency. Utility Model Content

[0029] Raw material supply organization 1;

The bottom of the workpiece is snapped and positioned on the transfer station 7. The drive mechanism includes a rotating disk 4, a guide roller 5, and a conveyor belt 6. The rotating disk 4 is driven to rotate and is mounted on the ring-shaped conveying mechanism 3. It and the conveyor belt 6 are linked to each other through side meshing or friction. The rotating disk 4 can be a gear or a sprocket, and the conveyor belt 6 is specifically a corresponding flexible toothed ring or chain. Alternatively, the surfaces of the rotating disk 4 and the conveyor belt 6 are in close contact and synchronous operation is achieved through friction between the two when the rotating disk 4 is driven to run.

[0031] The guide roller 5 abuts against the side of the conveyor belt 6, the transfer station 7 is positioned at the top of the conveyor belt 6, the raw material supply mechanism 1 is connected to the annular conveyor mechanism 3 via the first robot arm 2, the first injection molding mechanism 8 and the second injection molding mechanism 10 are connected to the annular conveyor mechanism 3 via the second robot arm 9 and the third robot arm 11 respectively, the second injection molding mechanism 10 is connected to the finished product conveyor belt 12 via the third robot arm 11, and the first robot arm 2, the second robot arm 9, and the third robot arm 11 are connected to the gripper fingers 13 for material transfer via the adjustment mechanism. The gripper fingers 13 can be gripper cylinders.

[0032] Several rotating disks 4 are driven by motors 14 and arranged at the corners of the conveyor belt 6.

The barriers, in conjunction with the rotating disk 4 and the guide rollers 5, further improve the stability of the conveyor belt 6 during operation.

[0035] The top surface of the annular conveyor mechanism 3 has a base 18 disposed on the inner side of the conveyor belt 6. The outer side of the base 18 is integrally connected to the annular first sealing plate 19 via an extension plate 20.

The X-axis drive device 22, Y-axis drive device 23, and Z-axis drive device 24 are used to adjust the three-dimensional position of the gripper finger 13, improving the flexibility of the robot. When the transfer station 7 moves to the loading / unloading point of the corresponding injection molding mechanism and the robot, the annular conveyor mechanism 3 stops operating and, in conjunction with workpiece position monitoring equipment such as an industrial camera, determines the workpiece position to achieve stable loading / unloading operations for the robot.

[0037] The working principle of a feeding device for continuous production of multiple injection molding in this embodiment includes: In use, the first robotic arm 2 positions the workpiece material on the raw material supply mechanism 1 on a transfer station 7; the motor 14 drives the rotating disk 4 to rotate, thereby driving the conveyor belt 6 to operate, and the transfer station 7 moves synchronously to transport the workpiece material to the next process; the second robotic arm 9 clamps the workpiece material and moves it to the first injection molding mechanism 8 for one injection molding to form a semi-finished workpiece; the second robotic arm 9 repositions the semi-finished workpiece on the transfer station 7 and moves it to the second injection molding mechanism 10; the third robotic arm 11 moves the semi-finished workpiece to the second injection molding mechanism 10, and after completing the second injection molding, the third robotic arm 11 moves the formed finished product to the finished product conveyor belt 12 and transports it to the next process section.

[0038] In summary, due to the adoption of the above technical solution, the feeding device for continuous production of multi-injection molding in this embodiment has the following advantages compared with the prior art:

[0039] This utility model's feeding device, through a single ring conveyor mechanism in conjunction with a robotic arm, can sequentially transport workpieces from the raw material supply mechanism to each injection molding unit, achieving cyclic feeding and seamless connection and linkage of multiple injection molding processes. This enables continuous production and automated loading and unloading, improving production efficiency while reducing the space occupied by the injection molding equipment and lowering costs. The robotic arm, working in conjunction with a transfer station, ensures stable workpiece positioning, guaranteeing stable and efficient transfer. The cyclical transport at the transfer station, utilizing a rotating disc, guide rollers, conveyor belt, barriers, and sealing plates, further enhances workpiece conveying efficiency.
