Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a feeding device for automatic injection molding assembly. Background Technology

[0002] In the production of plastic toys, the various parts of the toy, such as the shell and connecting parts, are first injection molded. After the various parts are processed, they are then precisely assembled by automated assembly equipment to complete the overall assembly of the toy. However, in order to simplify the processing steps, the workpieces are directly discharged to automated assembly equipment after injection molding. Then, with the help of robotic technology, the various workpieces are automatically assembled, reducing human intervention.

[0003] Currently, a vibratory feeder is installed between injection molding equipment and automated assembly equipment. This allows multiple individual workpieces to be arranged in an orderly manner, so that the automated assembly equipment can assemble the various parts of the product into a complete product. The inner wall of the vibratory feeder is equipped with a spiral conveyor, and the workpieces are discharged from the bottom up. The workpieces discharged from the injection molding machine are directly fed to the center position of the bottom of the vibratory feeder. However, during this process, some workpieces may feed onto the spiral conveyor without any limit on their position, which will disrupt the orderly arrangement of the workpieces on the spiral conveyor. This will result in a disordered arrangement of the workpieces fed to the automated assembly equipment later, affecting the robot's accurate gripping of the workpieces. To address the shortcomings of the existing technology, we propose a feeding device for automatic injection molding assembly to solve the above problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides a feeding device for automatic injection molding assembly, which solves the problem that when the injection molding equipment feeds workpieces into the vibratory feeder, some workpieces will feed onto the spiral conveyor without being able to reach the limit position. This causes the orderly arrangement of workpieces on the spiral conveyor to be disrupted, resulting in a messy workpiece arrangement when fed to the automated assembly equipment later. This affects the robot's accurate gripping of workpieces at the automated assembly equipment. The device enables the injection molding equipment to limit the feeding of workpieces into the vibratory feeder.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a feeding device for automatic injection molding assembly.

[0030] According to the appendix Figure 1-6 As shown, the system includes a vibratory feeder 1, a spiral conveyor 2 located inside the vibratory feeder 1, and a discharge channel 3 located on the outer wall of the vibratory feeder 1. The vibratory feeder 1 is positioned between the injection molding machine and the automated assembly equipment, which are not specifically shown in the attached drawings. During operation, the plastic raw material is first heated and melted by the injection molding machine and injected into the mold cavity. After cooling and solidification, a plastic workpiece is formed. Multiple sets of plastic workpieces are discharged into the vibratory feeder 1 through the discharge port. The vibratory feeder 1 arranges the multiple sets of plastic workpieces in an orderly manner on the spiral conveyor 2 through its vibration. The spiral conveyor 2 then discharges the multiple sets of workpieces sequentially into the discharge channel 3. The multiple sets of workpieces are then discharged into the automated equipment through the discharge channel 3. At this time, the automated equipment uses robotic technology to directly perform a series of assembly operations such as gripping, positioning, and assembling these injection-molded workpieces on the automated equipment's production line, making the overall processing relatively convenient.

[0031] See attached document Figure 2-5A feeding mechanism 4 is provided on the upper part of the vibratory feeder 1. This feeding mechanism 4 limits the feeding trajectory of the workpiece exiting the injection molding equipment when it enters the vibratory feeder 1, preventing the workpiece from contacting the orderly arranged workpieces on the spiral conveyor 2. The feeding mechanism 4 includes a first limiting frame 41 and a second limiting frame 42, which are mounted on the upper part of the vibratory feeder 1. An extension plate 43 for telescopic connection between the first limiting frame 41 and the second limiting frame 42 is fixedly provided on one side of the second limiting frame 42, and a guide frame 431 is fixedly provided at one end of the extension plate 43. A guide hole 432 for the guide frame 431 to move and limit its movement is provided on the outer wall of the first limiting frame 41. An electric lifting mechanism 44 is located on one side of the vibratory feeder 1. The first limiting frame 41 and... The electric lifting platforms 44 are fixedly connected. Through the electric lifting platforms 44, the distance between the bottom surface of the first limiting frame 41 and the second limiting frame 42 and the inner bottom surface of the vibrating plate 1 can be adjusted. The fixed frame 411 is fixedly installed on the outer wall of the first limiting frame 41. An adjusting screw 45 for threaded connection with the guide frame 431 is rotatably provided on one side of the fixed frame 411. By rotating the adjusting screw 45, the guide frame 431 moves under the action of the threaded connection between the adjusting screw 45 and the guide frame 431, thereby driving the extension plate 43 and the second limiting frame 42, which are fixedly connected to the guide frame 431, to move, so as to adjust the overall limiting space of the first limiting frame 41 and the second limiting frame 42, so that workpieces of different sizes can move smoothly within the first limiting frame 41 and the second limiting frame 42.

[0032] See attached document Figure 3-4 The lower inner walls of the first limiting frame 41 and the second limiting frame 42 are both rotatably equipped with cleaning components 6, such as cleaning brushes. The cleaning components 6 can clean the workpiece before it is discharged into the vibrating plate 1.

[0033] See attached document Figure 2-3The auxiliary component 5 is disposed on the top surface of the two sets of limiting frames. The auxiliary component 5 connects the discharge position of the injection molding equipment with the feeding position of the first limiting frame 41 and the second limiting frame 42. The auxiliary component 5 includes a first conveyor frame 51 and a second conveyor frame 52 for guiding the injection molded parts into the feed, and a connecting plate 53 fixedly disposed on one side of the second conveyor frame 52 for telescopic connection between the first conveyor frame 51 and the second conveyor frame 52. The top surface of the electric lifting platform 44 is provided with a slide rail 54 for limiting the movement of the second conveyor frame 52. The second conveyor frame 52 is located away from the slide rail 54. One end is fixedly connected to the top surface of the second limiting frame 42, and both ends of the first conveyor frame 51 are fixedly connected to the top surfaces of the electric lift 44 and the first limiting frame 41, respectively, so that when the first limiting frame 41 and the second limiting frame 42 are extended and retracted, the first conveyor frame 51 and the second conveyor frame 52 can be extended and retracted equally. A set of baffles 7 are fixedly provided on the top surfaces of the first limiting frame 41 and the second limiting frame 42. When the workpiece enters the combined limiting frame from the combined conveyor frame, the baffles 7 can prevent the workpiece from falling into the external environment.

[0034] See attached document Figure 5-6 A locking assembly 46 is provided on one side of the fixing frame 411. The locking assembly 46 is used to lock the adjusting screw 45 and the fixing frame 411. The locking assembly 46 includes a cover 461 fixedly disposed on one side of the fixing frame 411, a toothed ring 462 fixedly disposed on the outer wall of the adjusting screw 45, a toothed block 463 slidably disposed inside the cover 461, and a locking screw 464 rotatably disposed inside the cover 461 to control the engagement of the toothed block 463 and the toothed ring 462. A bearing 465 is fixedly disposed on the top surface of the toothed block 463. The outer wall of the end of the locking screw 464 extending into the inside of the cover 461 is fixedly connected to the inner wall of the bearing 465. With the assistance of the bearing 465 and the limiting block on the outer wall of the toothed block 463, when the locking screw 464 is rotated, the toothed block 463 can only move in a straight line and will not rotate in a circle with the locking screw 464.
