Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding, in particular to an ultrasonic plastic welding machine for rapid welding of magnetic building blocks. Background Art

[0002] An ultrasonic welding machine generates high-voltage and high-frequency signals of 20KHz or 15KHz by a generator. Through a transducer system, the signals are converted into high-frequency mechanical vibrations and applied to plastic workpieces. The temperature at the interface is increased by the friction between the workpiece surfaces and among molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melts, and then fills the gaps between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, thus achieving the welding purpose.

[0003] In the prior art, since the ultrasonic welding machine performs single-station operation, manual loading and unloading and welding are carried out alternately. The loading and unloading operations can only be carried out after welding is completed, resulting in a large amount of ineffective downtime, high equipment vacancy rate, and greatly reducing the production efficiency. Summary of the Utility Model

[0004] The utility model discloses an ultrasonic plastic welding machine for rapid welding of magnetic building blocks, aiming to solve the technical problem that due to the single-station operation of the ultrasonic welding machine, the loading and unloading operations can only be carried out after welding is completed, resulting in a high equipment vacancy rate.

[0005] To achieve the above object, the utility model adopts the following technical solution: an ultrasonic plastic welding machine for rapid welding of magnetic building blocks, comprising a workbench; a column, the column is fixedly connected to the top of the workbench; a mounting frame, the mounting frame is fixedly connected to the outside of the column; a hydraulic rod, the hydraulic rod is fixedly connected to the inner wall of the top of the mounting frame; an ultrasonic vibrator, the ultrasonic vibrator is fixedly connected to the driving end of the hydraulic rod; a welding head, the welding head is arranged at the bottom of the ultrasonic vibrator; an upper mold, the upper mold is fixedly connected to the bottom of the welding head; a quick switching module, the quick switching module is located above the workbench, the quick switching module includes a threaded rod, a rotating hole is opened on the workbench, one end of the threaded rod is rotatably connected to the rotating hole through a bearing, and the other end is connected to the output shaft of a driving motor fixedly connected to the top of the workbench, a sliding seat is threadedly connected to the outside of the threaded rod, a double-groove mold is arranged above the sliding seat, two positioning grooves are opened on the top of the double-groove mold, the quick switching module further includes a fixed rod, both ends of the fixed rod are fixedly connected to the workbench, the fixed rod penetrates through the sliding seat and is slidably connected to the sliding seat, two symmetrically arranged mounting parts are fixedly connected to the top of the workbench, circular holes are opened on both mounting parts, sliding rods are fixedly connected to both circular holes, trigger rods are slidably connected to the outside of both sliding rods, and reset springs are wound around the outside of both sliding rods, one end of both reset springs is fixedly connected to the inner wall of the corresponding mounting part, and the other end of both reset springs is fixedly connected to one side of the corresponding trigger rod, microswitches are fixedly connected to both mounting parts, and the trigger buttons of both microswitches face the corresponding trigger rods.

[0006] By setting up the quick switching module, while welding in one of the positioning grooves of the double-groove mold, another set of magnetic building block components is placed in the other positioning hole of the double-groove mold. After welding is completed, the hydraulic rod retracts to drive the upper mold to reset. The driving motor is started to rotate the threaded rod, and the sliding seat is driven to slide along the fixed rod to one side until the sliding seat contacts the trigger rod. At this time, the trigger rod compresses the reset spring and slides on the outside of the sliding rod, triggering the microswitch, transmitting an electrical signal to the driving motor, causing the driving motor to stop rotating the threaded rod, driving another set of magnetic building block components to reach directly below the upper mold. While starting welding again, the welded magnetic building blocks can be collected and new components can be continuously placed. Through double-groove alternating welding, continuous production is formed, effectively reducing the equipment idle time. At the same time, through the coordinated action of the trigger rod and the microswitch, the alignment accuracy of the mold and the automation degree of the production process are improved, significantly enhancing the welding production efficiency and convenience.

[0007] In a preferred embodiment, a positioning and fixing module is provided on the sliding seat. The positioning and fixing module includes a clamping groove, and the double-groove mold slides in the clamping groove. Two positioning holes are formed in the double-groove mold, and two sliding holes are formed in the sliding seat. The two sliding holes correspond to the two positioning holes. Sliding members are slidably connected in the two sliding holes. Ball members are fixedly connected to the tops of the two sliding members. Positioning springs are fixedly connected to the bottoms of the two sliding members. One ends of the two positioning springs away from the sliding members are fixedly connected to the sliding seat. A control panel is fixedly connected to one side of the workbench.

[0008] By providing the positioning and fixing module, when the double-groove mold needs to be replaced, press down the ball member from the positioning hole, forcing the sliding member to compress the positioning spring and slide downward, so that the sliding member disengages from the positioning hole. At the same time, pull the double-groove mold outward to disengage the double-groove mold from the clamping groove, and install the new double-groove mold in the reverse direction, which can achieve tool-free disassembly and assembly, and significantly shorten the mold replacement time.

[0009] As can be seen from the above, the ultrasonic plastic welding machine for rapid welding of magnetic building blocks provided by the present invention forms continuous production through double-groove alternating welding in the rapid switching module, effectively reducing the equipment idle time. At the same time, through the synergistic effect of the trigger rod and the microswitch, the alignment accuracy of the mold and the automation degree of the production process are improved, significantly enhancing the welding production efficiency and convenience.
