Description

Technical Field

[0001] This utility model belongs to the field of laser welding technology, and specifically refers to a laser welding structure. Background Technology

[0002] PE material, especially PE pipes, is widely used in the sanitary ware industry.

[0003] In existing products, a connector is typically attached to one or both ends of the PE pipe to enable its wide applicability. Currently, the connection between the connector and the PE pipe is usually achieved using laser welding. However, existing welding processes involve fixing the laser head in one place and rotating the workpiece during welding to achieve a complete circumference weld. Therefore, the welding position that a single laser head can achieve is extremely limited. The entire molten line must be welded by matching the rotation of the workpiece, which not only results in low efficiency but also requires a high-precision and highly stable rotating device due to its dependence on the rotational movement of the workpiece. Utility Model Content

[0004] The main purpose of this invention is to provide a laser welding structure that solves the problems existing in the prior art. Welding can be completed with only one laser head and without the need to rotate the workpiece.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A laser welding structure includes a relatively fixed workpiece to be welded and a laser head, as well as a prism and several reflectors. The workpiece is detachably placed on a support and fixed in place without rotation. The workpiece includes a first part and a second part, with the end of the second part inserted into the end of the first part, and a fusion line is pre-set on the end surface of the first part. The laser head emits light towards the prism. The prism refracts the laser emitted by the laser head and splits it into at least two beams. The refracted laser beams change direction after passing through at least one reflector and point towards the fusion line of the workpiece. All the refracted laser beams combine to cover the complete fusion line.

[0007] The first part is a PE pipe, and the second part is a connector.

[0008] The bracket has a fixing ring for fixing the second part, and the fixing ring has an opening and closing function.

[0009] Preferably, the retaining ring is locked by means of screws or snap-fit ​​connection.

[0010] After adopting the above technical solution, the present invention has the following technical effects:

[0011] This invention combines a laser head with a prism and a reflector, enabling a single laser head to weld multiple positions on a workpiece simultaneously. The workpiece no longer needs to rotate, thus expanding the welding process beyond rotating bodies and improving welding efficiency. By utilizing the refraction of the prism and the reflection of the reflector, various effects such as "laser beam splitting" and "directional welding" can be achieved. This allows the laser emitted by a laser head with a fixed angle to illuminate a designated position after refraction and several reflections to complete the welding. Attached Figure Description

[0016] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0017] refer to Figure 1 , 2 As shown, this utility model discloses a laser welding structure, including a relatively fixed workpiece 1 to be welded and a laser head 2, as well as a prism 3 and several reflectors 4.

[0018] The workpiece 1 to be welded is detachably placed on a support 5 and fixed in place without rotating. The workpiece 1 includes a first part 11 and a second part 12. The end of the second part 12 is inserted into the end of the first part 11, and the end surface of the first part 11 is pre-set with a fusion line 10.

[0019] The laser head 2 emits light towards the prism 3;

[0020] Prism 3 refracts the laser emitted by laser head 2 and splits it into at least two beams;

[0021] After being refracted, the laser changes direction after passing through at least one reflector 4 and points to the melting line 10 of the workpiece 1;

[0022] All the refracted laser beams combined together to cover the complete molten line 10.

[0023] Through the above scheme, this utility model combines the laser head 2 with the prism 3 and the reflector 4, enabling a single laser head 2 to weld multiple positions of the workpiece 1 simultaneously. The workpiece 1 no longer needs to rotate, making the welding process no longer limited to rotating bodies and improving welding efficiency. By utilizing the refraction of the prism 3 and the reflection of the reflector 4, a variety of effects such as "laser beam splitting" and "directional welding" can be achieved, allowing the laser emitted by the laser head 2 at a fixed angle to shine on the designated position after refraction and several reflections to complete the welding.

[0024] The following are specific embodiments of the present invention.

[0025] The first part 11 is a PE pipe (polyethylene pipe), and the second part 12 is a connector.

[0026] The bracket 5 has a fixing ring 51 for fixing the second part 12. The fixing ring 51 has an opening and closing function. When it is opened, it is convenient to take out the second part 12. When it is closed, it fixes the second part 12.

[0027] Furthermore, the aforementioned fixing ring 51 is locked by means of screw fastening, snap-fit ​​connection, etc., which can prevent the fixing ring 51 from being easily loosened.

[0028] The laser head 2 mentioned above refers to a laser emitter or laser emitting device used in the industry to achieve laser welding.

[0029] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
