Description

Technical Field

[0001] The utility model relates to the technical field of copper pipe processing equipment, in particular to a laser coding device suitable for copper pipes. Background Art

[0002] Copper pipe fittings are commonly used pipe connectors in floor heating systems, with good thermal conductivity and corrosion resistance. The following is an introduction to floor heating copper pipe fittings: 1. Material: Floor heating copper pipe fittings are generally made of high-quality oxygen-free copper, with good thermal conductivity and corrosion resistance. 2. Type: Floor heating copper pipe fittings include elbows, tees, crosses, straights and other types, and you can choose the appropriate pipe fittings according to actual needs. 3. Connection method: There are two main connection methods for floor heating copper pipe fittings: welding and crimping. Welding connection requires the use of welding tools for heating and welding, and the connection is firm and reliable; crimping connection is to connect the pipe fittings to the pipeline through a special crimping tool, which is simple and quick. 4. Advantages: Good thermal conductivity: Copper has good thermal conductivity, can effectively conduct heat energy, and improve the heating effect of the floor heating system. 5. Good corrosion resistance: Copper has good corrosion resistance, is not easily affected by water quality, and has a long service life. 6. High strength: Copper pipe fittings have high strength and pressure resistance, and can withstand large water pressure and temperature changes. To sum up, floor heating copper pipe fittings are commonly used pipe connectors in floor heating systems. They have good thermal conductivity and corrosion resistance, and can improve the heating effect and service life of floor heating systems.

[0003] Copper pipe fittings are extremely durable parts that can maintain their normal functions for more than 10 years. Conventional marking methods, such as sticking physical labels and binding anti-counterfeiting buckles, will be lost or unrecognizable due to long-term use, making it difficult to track the information of copper pipe fittings. Once a failure occurs, it will be impossible to trace the source. Therefore, it is best to generate an indelible identification code on the copper pipe fittings to facilitate tracking and tracing.

[0004] As an example of the prior art, refer to patent document CN110560917B. The present invention relates to a laser coding device and coding method for automobile body coding, which includes: a motion mechanism; a laser coding device connected to the motion mechanism; and a main control device connected to the motion mechanism and the laser coding device, used to obtain the automobile model information and control the laser coding device to generate laser for coding, and the main control device stores the coding content corresponding to different models. The present invention can be applicable to the flexible coding requirements of multiple models at the same time in the presence of body manufacturing deviations, and can also meet the special coding requirements of materials such as high-strength steel.

[0005] Based on the technical examples and other existing technologies, the applicant found some drawbacks in the test production, for example: 1. The equipment in the technical examples is only suitable for the processing of glass products, not for copper pipe fittings. The reason is that copper pipe fittings have lower requirements for the outer surface, and generally have a frosted rough outer surface. However, the existing laser coding technology and equipment are only suitable for printing on products with smooth surfaces (such as glass, stainless steel, etc.), and cannot be directly printed on rough surfaces. If you insist on printing on a rough surface, there will be problems such as unclear printing and unrecognizable identification codes (such as DM codes), and the defective rate is extremely high. ; 2. The identification codes printed in sequence are easy to be identified, which makes it easy to imitate counterfeit products with identification codes on the market; 3. One machine is used for one purpose. The product models and shapes of copper pipe fittings are diverse. A single existing device cannot meet the coding needs of many copper pipe fittings; 4. There is no suitable supporting processing tooling, and they need to be processed one by one. Batch loading and laser coding operations cannot be realized, resulting in low processing efficiency; 5. Even if the identification code is laser printed on the copper pipe fitting, various adverse factors such as oxidation and scratches will appear on the surface during later use, resulting in the identification code being unable to be recognized in the later stage.

[0060] Embodiment 2

[0061] Based on the structure of the first embodiment, this embodiment provides a preferred structural solution for the tooling assembly 2: Figure 2 to Figure 6The tooling assembly 2 includes a tooling turntable 21, a driving motor 22 acting on the tooling turntable 21, a row of tools 23 and a second row of tools 24 arranged on the tooling turntable 21, and a storage slot 25 is provided on the row of tools 23 and the second row of tools 24. The rotation of the tooling turntable 21 can make the row of tools 23 and the second row of tools 24 interchangeable. According to the needs, multiple products can be accommodated on the row of tools 23 and the second row of tools 24 at the same time, so that when the row of tools 23 is being laser-coded, the staff or the automated robotic arm can load and unload the products on the second row of tools 24; when the row of tools 23 is processed, the row of tools 23 and the second row of tools 24 are interchanged, and at this time, when the second row of tools 24 is being laser-coded, the staff or the automated robotic arm can load and unload the products on the row of tools 23. Therefore, the use of the tooling assembly 2 structure of this embodiment can achieve a balanced production process, prevent time waste and discontinuous segmented supply problems, and improve production efficiency and cost control.

[0062] Preferably, the tooling assembly 2 includes a plurality of product brackets 26, and the lower end of the product bracket 26 has a detachable mounting structure adapted to the first row of tooling 23 and the second row of tooling 24.

Firstly, there is enough space here to facilitate installation; secondly, there is a suitable distance from the heating wire 27 to make temperature monitoring more reasonable and accurate.
