DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Example

[0018] See also Figure 1 The utility model proposes a technical solution of a quasi-synchronous plastic welding device: a quasi-synchronous plastic welding device, comprising a lifting column 4 and a stand 11, specifically, a temperature control welding head module 5 is arranged on the lifting column 4; a temperature measuring module 8, a laser optical path module 9 and a camera module 10 are arranged on the temperature control welding head module 5, and a laser field lens 6 and a light filler 7 are arranged below the temperature control welding head module;

[0019] A welding fixture 2 is arranged at the center of the stand 11, and fixed cylinders are arranged at the four corners of the welding fixture 2. A fixed platform 12 fixedly connected to the fixed cylinder is arranged directly above the welding fixture 2, and a hole is left at the center of the fixed platform 12;

[0020] An electric cylinder 1 passing through the platform 11 is arranged at the center below the platform 11 . The top of the electric cylinder 1 is fixedly connected to the welding fixture 2 . The electric cylinder 1 is fixedly connected to the welding fixture 2 .

[0021] See also Figure 1 As shown, further, fixed cylinders are arranged on the four corners of the welding fixture 2, and a fixed platform 12 fixedly connected to the fixed cylinders is arranged directly above the welding fixture 2, and the central portion of the fixed platform 12 is a hole;.

[0022] In this embodiment, four fixed cylinders are provided on the welding fixture 2 so that the fixed fixture 2 can be pushed upward according to the drive of the electric cylinder 1. At the same time, the four fixed cylinders are fixedly connected to the fixed platform 12, so that the welding fixture 2 can better stabilize the plastic parts to be welded under the push of the electric cylinder 1.

[0023] See also Figure 1 As shown, further, a displacement sensor 3 is provided on the welding fixture 2 .

[0024] In this embodiment, a displacement sensor is provided on the welding fixture 2 to detect the displacement value in the pressing state before welding.

[0025] See also Figure 1 As shown, further, the number of displacement sensors 3 is even and they are all symmetrically arranged.

[0026] In this embodiment, the displacement sensors 3 are arranged in an even number and are symmetrically arranged, which can better record the displacement values.

[0027] See also Figure 1 As shown, further, a pressure sensor 13 is provided on the welding fixture 2 .

[0028] In this embodiment, a pressure sensor 13 is provided on the welding fixture 2 to detect the magnitude of the pressure applied to the product when the product is pressed.

[0029] See also Figure 1 As shown, further, the temperature-controlled welding head module 5 and the welding fixture 2 are connected to a computer.

[0030] The working principle of this utility model:

[0031] Put the product to be welded into the welding fixture 2 and input power to start. The electric cylinder 1 starts to operate, driving the welding fixture 2 to move upward and press the product. At this time, the system connects to the computer through the pressure sensor 13 to record the pressure; at the same time, through the displacement sensor 3 on the welding fixture 2, in the pressing state before welding, the displacement value at this time is recorded. When welding starts, the laser is emitted from the laser optical path module 9 in the laser welding head module 5 and reaches the welding surface. The temperature measurement module 8 tracks and records the welding surface temperature value of the laser welding path in real time. If the monitoring process exceeds the set temperature range, the system adjusts the output power value in real time to keep the temperature range in the specified range; the camera module 10 records the welding process and transmits it to the computer for data registration; after welding is completed, the temperature monitoring stops recording and automatically displays the temperature change curve, power curve, displacement curve, and pressure curve on its software screen.
