Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically to a continuous plastic parts welding device. Background Technology
[0002] In the field of plastic parts welding, continuous automated production has become a key trend for improving industrial efficiency, especially for mass-produced plastic products such as automotive parts and electronic casings, where the demand for high-precision welding is increasing. Currently, the industry generally uses vibration friction welding or hot plate welding processes, and related equipment is developing towards integration and high speed. However, there is still room for optimization in the automated loading and unloading process.
[0003] Existing plastic welding equipment uses symmetrically arranged slides to support the workpieces. The slidings are opened and closed by independent cylinders to transfer the welding station. Although the equipment can complete the basic welding action, the unloading process requires an additional pneumatic push rod. Furthermore, the positioning of plastic parts relies on manual placement or separate robotic arm systems, making it impossible to achieve synchronous unloading and positioning under a single motor drive.
[0004] The aforementioned existing technologies have significant limitations: First, the separation of the material feeding and welding movements leads to a longer cycle time, which restricts production efficiency; second, the independent drive of the feeding mechanism increases equipment costs and energy consumption; third, manual intervention in positioning can easily cause workpiece displacement, affecting welding accuracy; and finally, the coordination of multiple execution units is difficult, making it difficult to achieve continuous operation. These defects have become technical bottlenecks restricting efficient automated welding.

[0034] A convex plate 23 is slidably connected to the upper side of the slide block 4. The convex plate 23 is used to initially position the plastic part to prevent it from falling.

[0036] In this embodiment, after the two sets of plastic parts are welded on the slide block 4, the drive motor 9 starts and drives the rotating rod 10 to rotate, so that the first gear 11 fixed on it rotates synchronously. Since the first gear 11 meshes with the two sets of centrally symmetrically arranged first tooth plates 8 at the same time, it drives the symmetrically arranged first connecting rod 6 and second connecting rod 7 to slide in opposite directions along the translation groove 5, and drives the two sets of slide blocks 4 to move away from each other on the main body 1 of the device.
[0037] During this process, when the slide block 4 moves, it abuts against the slide rod 17, forcing the baffle 15 to retract into the mounting groove 14. At this time, the connecting plate 18 moves along with it and drives the second toothed plate 20 on it to move horizontally. Through the meshing transmission between the second gear 22 and the symmetrically arranged second toothed plate 20, the pusher plate 19 is pushed into the storage seat 12, and the plastic part to be processed is accurately pushed down onto the surface of the slide block 4 through the discharge port 13. The convex plate 23 achieves initial positioning to prevent it from falling.
[0038] Subsequently, the drive motor 9 reverses, and the two sets of slides 4 move towards each other to reset. At this time, the spring in the mounting groove 14 pushes the baffle 15 to extend and reset, and the connecting plate 18 drives the pusher plate 19 to return to the initial position. The upper plastic parts in the storage seat 12 automatically fall down. When the two sets of slides 4 move to the contact position, the slide plate 24 is squeezed and retracts into the slide 4, driving the slider 26 to slide along the guide groove 25 and compress the compression spring 27. At this time, the slide plate 24 and the third toothed plate 28 on the convex plate 23 are driven by the meshing of the third gear 29 to drive the convex plate 23 to automatically retract and release the limit, so that the two sets of plastic parts can accurately abut against the inclined surface of the slide 4. The welding equipment 3 completes the automatic welding. The whole process realizes the automated cycle of continuous feeding, positioning and welding through mechanical linkage, which greatly improves the work efficiency.
[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
