[0001] The utility model relates to the technical field of welding tools, and specifically, to a single-pendulum plastic hand-held welding head. Background Technique

[0002] In the existing welding technology field, the hand-held welding head is an important tool for performing fine welding work. However, there are some limitations in the design and function of traditional hand-held welding heads, making it difficult to meet the modern complex and fine welding requirements.

[0003] First of all, the focusing and collimation systems of many traditional hand-held welding heads are not precise enough to provide a stable and high-quality welding beam during the welding process. This may lead to unstable welding quality and affect the quality and performance of the product.

[0004] Secondly, traditional hand-held welding heads often lack intelligent monitoring and feedback systems, making it difficult for operators to monitor the welding process and the working state of the welding head in real time, and thus difficult to adjust the welding parameters in a timely manner to ensure the welding quality.

[0005] In addition, traditional hand-held welding heads also have deficiencies in ergonomic design. For example, the shape and weight distribution of the hand-held part may not be suitable for long-term hand-held operation, and the heat dissipation performance may also be poor. These may all affect the comfort and work efficiency of the operator. Content of the Utility Model

[0006] The purpose of the utility model is to provide a single-pendulum plastic hand-held welding head to solve the problem that there are some limitations in the design and function of traditional hand-held welding heads in the above-mentioned background technique, making it difficult to meet the modern complex and fine welding requirements.

[0007] To achieve the above purpose, the utility model provides a single-pendulum plastic hand-held welding head, including a housing. One end of the bottom of the housing is installed with a QBH connector. One end of the upper part of the housing is installed with an adjustment focus component. The outer end of the adjustment focus component is installed with a copper nozzle. A collimating mirror module is installed inside the housing near the QBH connector. A focusing mirror module is installed inside the housing near the adjustment focus component. An X-axis swing motor reflection lens module is installed between the focusing mirror module and the collimating mirror module. A protective mirror module is installed on one side of the focusing mirror module.

[0008] Preferably, a switch button is installed on one side of the middle part of the housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0023] The present utility model provides a single pendulum plastic hand-held welding head, as Figures 1 - 3 shown, which includes a housing 9. One end of the bottom of the housing 9 is installed with a QBH joint 1. One end of the upper part of the housing 9 is installed with an adjustment focus component 7. The outer end of the adjustment focus component 7 is installed with a copper nozzle 8. A collimating mirror module 10 is installed inside the housing 9 near the QBH joint 1. A focusing mirror module 3 is installed inside the housing 9 near the adjustment focus component 7. An X-axis swing motor reflection mirror module 2 is installed between the focusing mirror module 3 and the collimating mirror module 10. A protective mirror module 6 is installed on one side of the focusing mirror module 3. The adjustment focus component 7 is a conventional structure of a welding head in the prior art. By adjusting the focal length, it can ensure that the energy of the welding beam is more concentrated, thereby increasing the penetration depth and welding strength of the welding. This helps to reduce welding defects and improve the quality and performance of the welded joint.

[0024] In this embodiment, a switch button 5 is installed on one side of the middle of the housing 9 to control the switch of the laser emission outside the QBH joint 1.

[0025] Specifically, an intelligent monitoring display lamp 4 is installed on the outer side of the upper part of the housing 9. A pollution detector is installed inside the housing 9 to detect the pollution value of the lens. When the value reaches a preset value, a signal is transmitted to the external control system, and the intelligent monitoring display lamp 4 is controlled to light up for alarm.

[0026] Furthermore, the X-axis swing motor reflection mirror module 2 includes a swing motor 21. The output shaft of the swing motor 21 is installed with a reflection mirror 22 to ensure the swing operation of the reflection mirror 22.

[0027] Furthermore, the collimating mirror module 10 is installed on the inner wall of the housing 9 to facilitate the installation and fixation of the collimating mirror module 10.

[0028] Furthermore, the focusing mirror module 3 and the protective mirror module 6 are installed on the upper inner wall of the housing 9 and are arranged parallel to each other.

[0029] Furthermore, the outer wall of the back of the housing 9 is an arc-shaped concave structure to facilitate hand holding.

[0030] Furthermore, heat dissipation holes are provided on the outer wall of the upper part of the housing 9 to improve the heat dissipation effect of the equipment housing 9.

[0031] When the pendulum plastic hand-held welding head of the utility model is in use, first, the QBH connector 1 is connected to fix the fiber laser, and the laser is emitted from inside the optical fiber. After being received and shaped by the collimating mirror module 10, the light is directly irradiated onto the X-axis swing motor reflection mirror module 2. Through the high-frequency swing of the swing motor 21, the reflection mirror 22 reflects the reflected light onto the swing focusing mirror module 3. When the lens is contaminated, it is fed back to the control system panel to prompt an alarm message, and the intelligent monitoring display light 4 is lit for prompting. The switch button 5 controls the switch to make the laser emit and work. Due to the dust pollution in the working environment, in order to avoid damage to the internal optical precision components, the protection mirror module 6 is used for protection, and the focusing point component 7 is adjusted for focal length adjustment to accurately position the welding, which can ensure the welding quality. The wire feeding guide is completed through the copper nozzle 8.

[0032] Finally, it should be noted that the intelligent monitoring display light 4, the swing motor 21, etc. in this embodiment, the electronic components in the above components are all general standard components or components known to those skilled in the art. Their structures and principles can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. At the idle place of this device, all the above electrical components are respectively connected through wires. The specific connection means should refer to the working sequence of each electrical component in the above working principle to complete the electrical connection, which is all well-known technology in the art.
