Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding machines, and in particular to a servo ultrasonic welding machine. Background Technology

[0002] The principle of ultrasonic welding is that the generator produces a high-voltage, high-frequency signal of 20KHz (or 15KHz), which is converted into high-frequency mechanical vibration by the transducer system and applied to the plastic workpiece. The temperature of the interface is increased by friction between the workpiece surface and between molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface melts rapidly and fills the gap between the interfaces. When the vibration stops, the workpiece cools and solidifies under a certain pressure, thus achieving a high-quality weld.

[0003] With the development of existing ultrasonic welding machines, more and more new technologies are being applied to them. Among them, servo motor technology is widely used in ultrasonic welding machines. It greatly improves the control of ultrasonic welding pressure and depth, multi-segment speed, parameterization of wave emission time, welding accuracy and welding quality. However, when changing the mold of the welding head, since the mold is fixed with bolts, the operator needs to manually tighten the bolts. This fixing method is time-consuming and laborious. If the bolts are not tightened properly, the mold will become loose during use, affecting the welding. Therefore, a servo ultrasonic welding machine is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a servo ultrasonic welding machine, which aims to improve the problem in the prior art that "because the mold is fixed with bolts, the operator needs to manually tighten the bolts when fixing it. This fixing method is time-consuming and laborious. If the bolts are not tightened, the mold will become loose during use, affecting the welding".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a servo ultrasonic welding machine, comprising a movable frame, a welding machine body slidably connected to the front of the movable frame, a base fixedly connected to the bottom of the movable frame, an installation mechanism installed on the inner wall of the welding machine body, the installation mechanism comprising a quick positioning component and a fixing component, the fixing component comprising a connecting frame, the connecting frame slidably connected to the inner wall of the welding machine body, a movable ring fixedly connected to the bottom of the connecting frame, a connecting block provided on the outer wall of the movable ring, a fixing rod fixedly connected to the right end of the connecting block, a connecting rod sleeved on the outer wall of the fixing rod, and a fixing block fixedly connected to the outer wall of the fixing rod.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a servo ultrasonic welding machine, including a movable frame 3 that moves the welding machine body 1. The welding machine body 1 is slidably connected to the front of the movable frame 3. The welding machine body 1 is the main body of the ultrasonic welding machine. A base 2 for placing welding materials is fixedly connected to the bottom of the movable frame 3. An installation mechanism for quickly installing a mold 4 is installed on the inner wall of the welding machine body 1. The installation mechanism includes a quick positioning component and a fixing component. The fixing component includes a connecting frame 7 that moves other components. The connecting frame 7 is slidably connected to the welding machine body 1. The inner wall of the machine body 1 slides up and down on the inner wall of the welding machine body 1. The bottom of the connecting frame 7 is fixedly connected to a moving ring 9 for driving the connecting block 11. The outer wall of the moving ring 9 is provided with a connecting block 11 for driving the fixed rod 10 to move. The right end of the connecting block 11 is fixedly connected to a fixed rod 10 for clamping and fixing the mold 4. The outer wall of the fixed rod 10 is sleeved with a connecting rod 5 for supporting the fixed rod 10. The fixed rod 10 rotates and slides on the inner wall of the connecting rod 5. The outer wall of the fixed rod 10 is fixedly connected to a fixed block 15 for clamping and fixing the mold 4.

[0031] Reference Figure 3 , Figure 4 The quick positioning component includes a mounting base 8 for mounting the mold 4. The mounting base 8 is fixedly connected to the bottom of the welding machine body 1. The mold 4 is fixed to the welding machine body 1 through the mounting base 8. The bottom of the mounting base 8 is provided with a mold 4 for pressing and fixing the welding material. The bottom of the mounting base 8 is fixedly connected with a magnet 13 for adsorbing and positioning the mold 4. The magnet 13 and the magnet 2 14 attract each other, allowing the operator to quickly position and install the mold 4. The upper surface of the mold 4 is fixedly connected with a magnet 2 14 for quick installation. The connecting rod 5 is fixedly connected to the bottom of the welding machine body 1 to support the fixing rod 10. The outer wall of the mold 4 is provided with a fixing groove 16. The fixing block 15 is inserted into the fixing groove 16 to fix the mold 4.

[0032] Reference Figure 2 , Figure 3 , Figure 4 The lower surface of the mounting base 8 is fixedly connected to a buffer pad 12, which is used to reduce the vibration noise generated between the mounting base 8 and the mold 4. The connecting block 11 is C-shaped and is used to fit the moving ring 9. When it moves downward, it will twist the fixing rod 10 to rotate. There are multiple sets of connecting rods 5. The multiple sets of connecting rods 5 are arranged in a rotating array with the center line of the moving ring 9 as the rotation axis, which can stably fix the mold 4. The cross-sectional shape of the fixing block 15 is triangular, which makes it easier to disengage from the fixing groove 16. The inner wall of the welding machine body 1 is fixedly connected to an electric push rod 6 for pushing the connecting frame 7. The output shaft of the electric push rod 6 is fixedly connected to the upper surface of the connecting frame 7. Pushing and pulling the connecting frame 7 completes the fixing and disassembly of the mold 4.

[0033] Working principle: When mold 4 needs to be replaced, the operator first activates the electric push rod 6, which pushes the connecting frame 7 downward. The connecting frame 7 drives the moving ring 9 downward, and the moving ring 9 pushes the connecting block 11. When the C-shaped connecting block 11 is pushed, it causes the fixing rod 10 to move downward and rotate. At this time, the fixing block 15 disengages from the fixing groove 16. Then, the operator removes mold 4 from the mounting base 8 and replaces it with another mold 4. During installation, simply place mold 4 under the mounting base 8. Magnet 13 and Magnet 2 14 attract each other. Then rotate mold 4 to align the fixing groove 16 and the fixing block 15. The operator does not need to manually remove the fixing components to prevent the fixing components from pinching the operator's fingers during fixing. Activate the electric push rod 6, which pulls the moving ring 9 with the connecting frame 7. When the moving ring 9 moves upward, the connecting block 11 drives the fixing rod 10 to move upward and rotate, thus completing the fixing of mold 4.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
