Description

Technical Field

[0001] This utility model relates to a welding device, and more particularly to a vibration friction plastic welding device. Background Technology

[0002] With the increasing proportion of plastic parts in industries such as automobiles and sanitary ware, some parts that cannot be formed in one step, such as car lights and toilet seats, must undergo secondary welding and fusion to become finished products. Existing vibratory friction plastic welding equipment generally uses a vibratory platform cylinder as the power source, and simultaneously requires operating the machine head to move back and forth. This is not only complex to operate, but also makes it difficult to accurately control the welding depth, thus affecting the product welding qualification rate. Therefore, existing vibratory friction plastic welding equipment needs further improvement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a vibration friction plastic welding equipment that can not only produce continuously, improve efficiency, and save labor, but also make the welding depth easy to control, thereby improving the product welding qualification rate.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a vibration friction plastic welding equipment, including a frame, on which a vibration platform and a welding head are provided. The welding head generates reciprocating motion by switching on and off an electromagnet at a high frequency. The vibration platform slowly rises under the control of a servo motor until the workpiece to be welded on the vibration platform comes into contact with the workpiece to be welded on the welding head. The servo motor is equipped with a reduction gearbox and an electromagnetic brake. A displacement gauge is also provided on the frame to control the welding depth during the welding process.

[0005] Furthermore, the drive shaft of the servo motor is connected to the sprocket box, and the electromagnetic brake is mounted on the drive shaft of the servo motor.

[0006] Furthermore, the electromagnet and the machine head are fixed to the frame via a machine head bracket.

[0007] Furthermore, the frame includes an upper frame and a lower frame, which are connected by four parallel columns, and a crossbeam is provided between two columns on the same side; the head frame is mounted on the upper frame, and the servo motor is mounted on the lower frame.

[0008] Furthermore, a grating is also provided on the frame.

[0009] Compared with the prior art, the present invention has the following advantages: The vibration friction plastic welding equipment provided by the present invention adopts servo control to slowly raise the vibration platform, and generates reciprocating motion by the high-frequency on and off of the electromagnet to attract and release the machine head; it can not only produce continuously, improve efficiency, and save labor; but also makes it easy to control the welding depth and improve the product welding qualification rate.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 This is a schematic diagram of the structure of the vibration friction plastic welding equipment of this utility model.

[0017] Please see Figure 1 The vibration friction plastic welding equipment provided by this utility model includes a frame 2, on which a vibration platform 3 and a welding head 10 are provided. The welding head 10 generates reciprocating motion by the high-frequency switching of an electromagnet 1. The vibration platform 3 is controlled by a servo motor 5 and slowly rises until the workpiece to be welded on the vibration platform 3 is in contact with the workpiece to be welded on the welding head 10. The servo motor 5 is equipped with a reduction gearbox 6 and an electromagnetic brake 8. The frame 2 is also equipped with a displacement ruler 4 to control the welding depth during the welding process.

[0018] The vibration friction plastic welding equipment provided by this utility model employs a servo-controlled vibration platform 3 that slowly rises, while the electromagnet 1 generates reciprocating motion by frequently switching the suction and release mechanism on the welding head. In use, two objects to be welded are placed, one fixed to the welding head 10 and the other to the stationary vibration platform 3. The servo motor 5 slowly raises the vibration platform 3 until the surfaces of the two objects to be welded are in contact. As the object on the welding head 10 moves, it generates high-speed friction and heat against the stationary object on the vibration platform 3. As the temperature rises, reaching the melting point of the material, the surfaces of the two objects in contact rapidly melt. During the friction process, the vibration platform 3 slowly rises with the object, and the welding surface melts deeper and deeper. Once the target melting depth is reached, the equipment stops friction. After cooling for a period of time, the two objects are firmly welded together. Specifically, the drive shaft of the servo motor 5 is connected to the sprocket box 7, and the electromagnetic brake 8 is mounted on the drive shaft of the servo motor 5.

[0019] Please continue reading Figure 2 The vibration friction plastic welding equipment provided by this utility model has an electromagnet 1 and a machine head 10 fixed on a frame 2 by a machine head frame 11.

[0020] Please continue reading Figure 3 The vibration friction plastic welding equipment provided by this utility model includes a frame 2 comprising an upper frame 201 and a lower frame 202, connected by four parallel columns 203. A crossbeam 204 is provided between two columns 203 on the same side. The head frame 11 is mounted on the upper frame 201, and the servo motor 5 is mounted on the lower frame 202. A light grating 9 is also provided on the frame 2 for safety protection. If any object enters the equipment window during welding, it will block the light beam of the light grating 9, causing the equipment to stop working and preventing personal injury accidents. The vibration platform 3 can be a general-purpose platform, and all parts are standard components. The structure is as follows: Figure 4 As shown, further details will not be elaborated here.

[0021] In summary, the vibration friction plastic welding equipment provided by this utility model adopts servo control to slowly raise the vibration platform 3, and generates reciprocating motion of the suction and release head 10 through the high-frequency on and off of the electromagnet 1; it can not only produce continuously, improve efficiency, and save labor, but also make the welding depth easy to control, thereby improving the product welding qualification rate.

[0022] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
