Description

Technical Field

[0001] This utility model belongs to the field of bathroom equipment parts processing technology, and specifically refers to a laser welding structure for a non-rotating PE material product. Background Technology

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

[0003] Typically, PE pipes are connected to a fitting at one or both ends to allow for wider application. Laser welding is frequently used to connect the fittings to the fittings. (Reference) Figure 1 As shown, the current welding method involves fixing the laser head 10 while the workpiece 20 rotates continuously to achieve full-circle welding.

[0004] However, with the widespread use of PE material, many non-rotating products are also connected using PE material. In particular, when a product has multiple channels in different directions inside, it cannot be directly formed by mold, so laser welding is required. The existing rotary welding method is not suitable for this type of product. Utility Model Content

[0005] The main purpose of this utility model is to provide a laser welding structure for non-rotating PE material products, which solves the problems existing in the prior art and enables laser welding of non-rotating bodies.

[0006] To achieve the above objectives, the solution of this utility model is: A laser-welded structure for a non-rotating PE material product includes a body and a plug. The body is injection molded and has parallel first, second, and third channels. The unidirectional ends of the first and second channels are respectively connected to the third channel laterally, and one end of the third channel has an opening. The surface of the plug has a positioning post, which is inserted into the opening. A laser welding line is formed around the opening and connected to the plug, and the body and the plug are fused together at the laser welding line position.

[0007] Both the body and the plug are made of PE material.

[0008] The first channel is parallel to the second channel and perpendicular to the third channel.

[0009] The outer diameter of the positioning post is equal to the inner diameter of the third channel.

[0010] The circumferential surface of the pipe formed by the first channel is provided with at least one annular groove, which is used to assemble a sealing ring.

[0011] The periphery of the opening is chamfered.

[0012] The first channel connects to both ends of the third channel, and the second channel connects to the end of the third channel.

[0013] After adopting the above technical solution, the present invention has the following technical effects: This invention relates to a non-rotating PE material product, which has at least three channels in different directions within its body. A large portion of the body can be injection molded, and one end of the originally closed channel (i.e., the third channel) can be opened for demolding. A plug is then used to weld the plug to the periphery of the opening using laser welding, thus sealing the opening. The plug's positioning post facilitates the positioning and engagement of the plug with the opening and prevents the plug from moving radially within the opening during welding, ensuring welding quality. Simultaneously, during welding, either the body or the laser head can move horizontally along a preset welding line to complete the laser welding. Attached Figure Description

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] refer to Figure 2-5 As shown, this utility model discloses a laser welding structure for a non-rotating PE material product, including a body 1 and a plug 2; The body 1 is formed by injection molding and has a first channel 11, a second channel 12 and a third channel 13 arranged in parallel. The ends of the first channel 11 and the second channel 12 in the same direction are connected to the third channel 13 laterally. One end of the third channel 13 is provided with an opening 131. The surface of the plug 2 is provided with a positioning post 21, which is inserted into the opening 131. A laser welding line a is formed between the opening 131 and the plug 2 through laser welding. The material of the body 1 at the position of the laser welding line a is fused together with the material of the plug 2.

[0022] Through the above solution, this utility model targets non-rotating PE material products, whose body 1 has at least three channels in different directions. A large portion of the body 1 can be injection molded, and one end of the originally closed channel (i.e., the third channel 13) can be opened as an opening 131 for demolding. Then, a plug 2 is used to weld it to the periphery of the opening 131 using laser welding, thus closing the opening 131. The positioning post 21 of the plug 2 facilitates the positioning and engagement of the plug 2 with the opening 131 and prevents the plug 2 from moving radially in the opening 131 during welding, ensuring welding quality. Meanwhile, referring to… Figure 5 As shown, during the welding process, either the body 1 or the laser head 10 can be moved horizontally along the preset welding line direction to complete the laser welding.

[0023] The following are specific embodiments of the present invention.

[0024] Both the main body 1 and the plug 2 mentioned above are made of PE (polyethylene) material.

[0025] The first channel 11 and the second channel 12 are parallel to each other and perpendicular to the third channel 13.

[0026] The outer diameter of the positioning post 21 is equal to the inner diameter of the third channel 13 to achieve a clearance fit between the positioning post 21 and the opening 131. This ensures that the positioning post 21 can be inserted into the opening 131 and prevents the positioning post 21 from shaking in the opening 131, thereby improving the welding quality.

[0027] The circumferential surface of the pipe formed by the first channel 11 is provided with at least one annular groove 111, which is used to assemble a sealing ring to achieve a sealed connection between the body 1 and the water pipe.

[0028] The periphery of the opening 131 is chamfered 132 to form an flared structure, making it easier for the positioning post 21 to be inserted into the opening 131.

[0029] The first channel 11 is connected to both ends of the third channel 13, and the second channel 12 is connected to the end of the third channel 12.

[0030] 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.
