[0006] The connecting block includes a horizontal plate and a vertical plate vertically connected thereto.

[0007] One end of the connecting bracket is connected to the laser tracker, and a guide rod is inserted into the connecting bracket and locked by a top locking piece at the top of the guide rod.

[0008] A first spring is provided on the outer sleeve of the guide rod, the top of the first spring abuts against the bottom of the connecting bracket, a cushion block is connected to the bottom of the first spring and is locked by a nut, the bottom of the guide rod is connected to the connecting block, the lower end of the connecting block is connected to the upper end of the copper rod, the side of the copper rod is connected to the vertical plate of the connecting block by a semi-threaded bolt, and a second spring is provided on the outer sleeve of the semi-threaded bolt.

[0009] The copper rods respectively abut against the first steel plate and the second steel plate which are vertically arranged, and the copper rods are 1 / 4 copper rods.

[0010] Furthermore, the horizontal plate and the vertical plate are combined to form an L-shaped structure.

[0011] Furthermore, the horizontal plate of the connecting block and the copper rod are fixedly connected by fully threaded bolts.

[0012] The beneficial effects of the present invention are:

[0013] The present invention is an anti-laser reflection device, which completes laser tracking by replacing the weld required by H-shaped steel with a 1 / 4 copper rod boss; the application of this mechanism in the laser welding tracking system can greatly improve the efficiency and accuracy of the workpiece, its degree of automation, and has the characteristics of simple structure, no safety hazards, and compactness.

[0017] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0018] As shown in the figure: one is a laser reflection protection device, such as Figure 1-3 As shown, laser tracking is completed according to the welding seam required by the copper rod 5 boss 14 instead of the H-shaped steel;

[0019] The device comprises a connecting bracket 1, a first spring 2, a guide rod 3, a connecting block 4, a copper rod 5, a second spring 6 and a cushion block 9;

[0020] The connecting block includes a horizontal plate 4.1 and a vertical plate 4.2 vertically connected thereto.

[0021] One end of the connecting bracket 1 is connected to the laser tracker, and a guide rod 3 is inserted into the connecting bracket and locked by a top locking piece 10 at the top of the guide rod.

[0022] The outer sleeve of the guide rod 3 is provided with a first spring 2, the top of the first spring 2 is pressed against the bottom of the connecting bracket, the bottom of the first spring is connected with a cushion block 9 and locked by a nut, the bottom of the guide rod is connected to the connecting block 4, the lower end of the connecting block 4 is connected to the upper end of the copper rod 5, the side of the copper rod 5 is connected to the vertical plate of the connecting block by a semi-threaded bolt 8, and the outer sleeve of the semi-threaded bolt 8 is provided with a second spring 6.

[0023] The copper rod 5 respectively abuts against the first steel plate 11 and the second steel plate 12 which are arranged vertically. The copper rod is a 1 / 4 copper rod.

[0024] The connecting block 4 is connected with the 1 / 4 copper rod through two full-thread bolts 7, three half-thread bolts 8, three second springs 6, two nuts 10 to form an anti-laser reflection component.

[0025] The horizontal plate 4.1 and the vertical plate 4.2 jointly form an L-shaped structure.

[0026] The horizontal plate of the connecting block is fixedly connected to the copper rod 5 by a fully threaded bolt 7 .

[0027] As attached Figure 1 As shown, the guide rod 3 and the connecting block 4 are connected and fixed to each other through threads. The connecting block 4 is connected to a 1 / 4 copper rod through two full-thread bolts 7, three half-thread bolts 8, three second springs 6, and two nuts 10 to form an anti-laser reflection device, thereby realizing a laser welding tracking system, and using a tracker to accurately track and locate the weld of the workpiece.

[0028] First, determine the positioning of the workpiece before this station, and then adjust the telescopic displacement of the spring in two directions to prevent laser reflection. The spring gives a 1 / 4 copper rod elastic force to act on two vertical H-steel plates to fix the position. After the fixation is completed, the main machine's drive device drives the entire machine to move in a straight line, thereby reflecting tracking; after entering the relevant parameters, the laser tracking operation begins.

[0029] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
