Description

Technical Field

[0001] This invention relates to the technical field of overhead conveyor production lines, specifically an overhead conveyor production line for injection molded parts assembly. Background Technology

[0002] Overhead conveyor (also known as overhead chain / aerial conveyor) is a continuous overhead track conveying equipment that uses a hanger to suspend the workpiece and travels along an overhead track. It does not occupy ground space, has flexible routes, and is suitable for long-distance, multi-process, and three-dimensional logistics scenarios. A Chinese patent document with publication number CN220479145U discloses a hollow rod suspended conveyor line, which includes an overhead track, a carriage, a hanger, and a traction unit. The hanger is assembled with the carriage and performs synchronous displacement movement with the carriage. When subjected to traction force from the traction unit, the carriage continuously moves along the closed loop formed by the overhead track to continuously supply hollow rods to be surface treated to the surface treatment equipment. The hanger includes a load-bearing assembly, a primary suspension component, and a torque generating unit. The load-bearing assembly is fixedly connected to the carriage. The primary suspension component is used to suspend the hollow rods and is freely rotatable and inserted into the load-bearing assembly. During the time the hollow rods pass through the surface treatment station, the torque generating unit activates to intermittently output rotational torque, allowing the primary suspension component to drive the hollow rods to perform circumferential rotational movement. However, when the suspended conveyor line in the above-mentioned scheme is used to assemble rod-shaped workpieces, it is inconvenient to remove and hang the rod-shaped workpieces from the suspended conveyor line, which affects the efficiency of workers in installing parts on the rod-shaped workpieces. Therefore, the present invention proposes a suspended conveyor production line for injection molding parts assembly to solve the above problems. Summary of the Invention

[0018] Please see Figures 1-19 The present invention provides the following three preferred embodiments: Example 1: A suspended conveyor production line for injection molded parts assembly includes a main track 1, a feeding structure 2, a drive wheel 3, and a traction cable 4. The main track 1 has a convex cross-section and is fixed to a mounting frame 6 on the top surface of a building via a primary connecting rod 5.

[0019] The feeding structure 2 includes a first bracket 9, a second bracket 10, rollers 11, and a positioning component 12. The first bracket 9 and the second bracket 10 are both Z-shaped and symmetrically arranged. The first bracket 9 and the second bracket 10 are each provided with a positioning groove 14 and a set of mounting holes 15. The first bracket 9 and the second bracket 10 are connected by bolts and nuts 16 for positioning. The traction cable 4 is positioned in the positioning groove 14. The upper end of the first bracket 9 and the second bracket 10 is rotatably mounted with rollers 11 through a rotating shaft 13. The positioning component 12 is connected to the lower end of the first bracket 9 and the second bracket 10 through a connector. The side wall of the positioning groove 14 is integrally formed with anti-slip protrusions. The anti-slip protrusions are semi-circular protrusions, and multiple anti-slip protrusions are evenly arranged on the side wall of the positioning groove 14.

[0020] The positioning component 12 includes an upper positioning plate 19 and a lower positioning plate 20, which are used to position and clamp the workpiece 7.

The mating block 25 and the upper connecting post 26 are integrally formed. The connecting magnet 27 is fixedly connected to the lower end of the upper connecting post 26. The connecting plate 24 is cast from ferromagnetic material and is used for adsorption and positioning. Located on the connecting magnet 27, a suspended conveyor production line for injection molding parts assembly is set up by a combination of main track 1, feeding structure 2, transmission wheel 3 and traction cable 4. The transmission wheel 3 drives the traction cable 4, thereby driving the feeding structure 2 to move along the main track 1 to realize the transfer of workpiece 7. The feeding structure 2 is set up to be composed of a first bracket 9, a second bracket 10, a roller 11 and a positioning component 12. The positioning component 12 is connected to the first bracket 9 and the second bracket 10 through a connector composed of a lower connecting column 23, a connecting plate 24, a docking block 25, an upper connecting column 26 and a connecting magnet 27. This makes it convenient for workers to separate the connecting plate 24 from the connecting magnet 27 so that workers can assemble the parts onto the workpiece 7.

[0021] The lower connecting column 23 and the upper positioning plate 19 are integrally formed. The connecting plate 24 and the upper end of the lower connecting column 23 are integrally formed. The lower end of the first bracket 9 and the second bracket 10 are provided with a docking groove 17 and a connecting column groove 18 on their inner sides. When the first bracket 9 and the second bracket 10 are actually docked, the docking block 25 is engaged in the docking groove 17, and the upper connecting column 26 is engaged in the connecting column groove 18. The side wall of the upper connecting column 26 is integrally formed with an anti-rotation protrusion 30, and the side wall of the connecting column groove 18 is provided with an anti-rotation groove 29. When the upper connecting column 26 is actually installed, the anti-rotation protrusion 30 is engaged in the anti-rotation groove 29.

[0022] Example 2: Based on Example 1, the main track 1, first bracket 9, second bracket 10, docking block 25, and upper connecting column 26 are all cast from non-conductive materials. Primary conductive plates 31 and secondary conductive plates are fixedly installed on the side walls of the docking groove 17 on the first bracket 9 and second bracket 10, respectively. Tertiary conductive plates 55 and quaternary conductive plates 56 are fixedly installed on the inner side walls of the upper ends of the first bracket 9 and second bracket 10, respectively. Primary and secondary conductors are pre-embedded in the first bracket 9 and second bracket 10, respectively. The plates 55 are electrically connected to each other via primary conductors, and the secondary and quaternary conductive plates 56 are electrically connected via secondary conductors. Positive and negative conductors are pre-embedded in the docking block 25 and the upper connecting post 26. The quinary conductive plate 32 and sixth conductive plate 33 are fixedly installed on the side wall of the docking block 25. The electromagnet 36 is fixedly installed on the outer side wall of the connecting magnet 27. The two ends of the positive conductor are electrically connected to the positive poles of the quinary conductive plate 32 and the electromagnet 36, respectively, and the two ends of the negative conductor are electrically connected to the negative poles of the sixth conductive plate 33 and the electromagnet 36, respectively.

[0023] A positive conductive rod 34 is fixedly installed on the outer side wall of the main track 1, and a negative conductive rod 35 is fixedly installed on the inner side wall of the main track 1. The positive conductive rod 34 and the negative conductive rod 35 are electrically connected to the positive and negative poles of the power supply, respectively. The positive conductive rod 34 and the negative conductive rod 35 form a break point at the worker's assembly station. When the feeding structure 2 is installed on the main track 1, the fifth-level conductive sheet 32 ​​and the sixth-level conductive sheet 33 are respectively set to be close to the positive conductive rod 34 and the negative conductive rod 35. By setting the positive conductive rod 34 and the negative conductive rod 35 and setting a break point at the worker's assembly station, the electromagnet 36 can be automatically energized and de-energized.

[0024] The attraction force of the connecting magnet 27 on the connecting plate 24 is 1.5 times the total mass of the workpiece 7, the positioning part 12, and the connecting part. The attraction force between the electromagnet 36 and the connecting plate 24 is equal to the attraction force between the connecting magnet 27 and the connecting plate 24. By fixing the electromagnet 36 on the outer wall of the connecting magnet 27 and ensuring that the attraction force of the connecting magnet 27 on the connecting plate 24 is 1.5 times the total mass of the workpiece 7, the positioning part 12, and the connecting part, it is easy for the staff to separate the connecting plate 24 from the connecting magnet 27 after the electromagnet 36 is de-energized. And after the electromagnet 36 is energized, the stability of the workpiece 7 during the turnover process can be ensured by the joint attraction of the electromagnet 36 and the connecting magnet 27 on the connecting plate 24.

[0025] Example 3: Based on Example 2, an outer fall arrestor 37 is fixedly installed on the mounting frame 6 via a secondary connecting rod 39, and an inner fall arrestor 38 is fixedly installed on the mounting frame 6 via a tertiary connecting rod 40. The inner fall arrestor 38 and the outer fall arrestor 37 are respectively located on the inner and outer sides of the main track 1, and the cross-sections of both the inner fall arrestor 38 and the outer fall arrestor 37 are continuously L-shaped and symmetrically arranged. A break point is formed between the inner fall arrestor 38 and the outer fall arrestor 37 at the worker's assembly station, connecting to the magnet 2. 7. When the connecting plates 24 are attracted to each other, there is a gap between the connecting plates 24 and the inner anti-fall component 38 and the outer anti-fall component 37. The upper surface of the connecting plates 24 is fixedly connected to the alignment tube 28. The inner diameter of the alignment tube 28 matches the outer diameter of the electromagnet 36. The alignment tube 28 is cast from a non-ferromagnetic material. By setting the outer anti-fall component 37 and the inner anti-fall component 38, and setting the break points on the outer anti-fall component 37 and the inner anti-fall component 38 corresponding to the worker assembly station, the workpiece 7 can be prevented from falling in the non-worker assembly area, thereby improving the safety of equipment operation.

A force rod hole 43 is provided through the bottom of the groove of the threaded hole 42. A positioning ball groove 44 and a ball groove 45 are provided on the side wall of the force rod hole 43. Positioning grooves 46 are provided on the side wall of the round holes at the upper ends of the first bracket 9 and the second bracket 10 for mounting the rotating shaft 13.

The outer end of the screw 50 is integrally formed with a nut 51, and the inner end of the screw 50 is integrally formed with a force-bearing rod 52. The inner end of the force-bearing rod 52 is frustoconical. When the screw 50 is actually tightened, the positioning ball 48 and the ball 49 are pushed outward under the force of the force-bearing rod 52. At this time, the outer spheres of the positioning ball 48 and the ball 49 are pushed into the positioning groove 46 and the rolling groove 47, respectively. By installing a single screw 50, the force-bearing rod 52 can be driven to push the positioning ball 48 and the ball 49, thereby achieving synchronous positioning of the rotating shaft 13 with the bracket structure and the roller 11, thereby improving assembly efficiency.

[0027] The outer side wall of the rotating shaft 13 is provided with an alignment groove 53. When the outer end face of the roller 11 is aligned with the alignment groove 53, the ball groove 45 and the rolling groove 47 are aligned. When the limit cap 41 is close to the first bracket 9 and the second bracket 10, the positioning ball groove 44 and the positioning groove 46 are aligned, which facilitates the alignment between the structures and improves the installation convenience of the rotating shaft 13 and the roller 11.
