Description

Technical Field

[0001] The present application relates to the field of automation equipment, and in particular to an automatic high-frequency welding device. Background Art

[0002] The heat sinks widely used in the market play a vital role in various heat dissipation systems. The basic structure of the heat sink usually includes a body with a heat exchange channel and ends connected to both ends of the body and connected to the heat exchange channel. Heat sinks are mainly used in various electronic equipment, mechanical equipment, automobile engines and other systems that require heat dissipation. Through efficient heat conduction and heat dissipation performance, the normal operation and service life of the equipment are ensured.

[0003] During the production process, the manufacture of heat sinks involves multiple steps, including assembly and welding of the body and the end. These production steps mainly rely on manual operation, especially in the welding process, which requires operators to perform delicate manual welding. This production method is not only time-consuming and labor-intensive, but also has high requirements on the skill level of operators, increasing the uncertainty and error probability in the production process.

[0004] More specifically, the welding process in the prior art is basically completed by manual operation, and workers need to make multiple adjustments and corrections during the operation, resulting in low production efficiency. In addition, the quality of the manual welding process is difficult to guarantee, and problems such as poor welding and leaking welding are prone to occur, which in turn affects the overall performance and service life of the heat sink.

[0005] In order to improve production efficiency and product quality and reduce manual intervention, automated welding technology has gradually attracted attention. Although automated welding technology can improve production efficiency and welding quality to a certain extent, its complex operation and maintenance requirements have put forward higher requirements on the technical capabilities of the factory. Therefore, how to improve the level of production automation while simplifying the operation and maintenance process and reducing the dependence on manual skills has become an urgent problem to be solved.

[0006] In summary, the existing heat sink production technology has problems such as cumbersome manual operation, low production efficiency, and difficult to ensure welding quality. A new technical solution is needed to improve the level of production automation, simplify the operation process, and improve production efficiency and product quality. Utility Model Content

[0031] like Figures 1 to 4 As shown, this embodiment discloses an automatic high-frequency welding device, which aims to realize the whole process of automatic loading, welding and unloading of workpieces, and improve production efficiency and welding quality. The device includes a loading component 1, a welding component 2 and an unloading component 3. The components are connected through a multi-axis transfer mechanism to realize the precise positioning and movement of the workpiece. The unloading component 3 and a multi-axis robot arm 4 realize processing output.

[0032] In terms of structural composition, the loading assembly 1 is composed of a first machine platform 101, an assembly mechanism, and a first XZ two-axis transfer mechanism 103 cooperating with the assembly mechanism.

[0033] In this embodiment, the first machine 101 is made of a steel structure frame to ensure the stability and durability of the equipment.

[0034] The assembly mechanism includes an actively upward loading platform 102, which is made of aluminum alloy and has the characteristics of lightness and high strength. The loading platform 102 is provided with at least one part for placing a working fixture, which is made of wear-resistant material to extend the service life.

[0035] The clamping group 103 cooperates with the loading machine platform 102 to clamp and place the workpiece.

[0036] More specifically, the material clamping group 103 is an electric clamping jaw, including a motor, a driving shaft connected to the motor, and a gear mechanism driven by the driving shaft. The gear mechanism includes a helical gear mounted on the driving shaft, a helical rack matched with the helical gear, and a clamping part hinged to a fixed part through a circular gear and driven by the helical rack to achieve upper and lower closure. The motor drives the helical gear to rotate through the driving shaft, the helical gear matches the helical rack, and the linear motion of the helical rack is converted into the closing motion of the clamping part through the circular gear, thereby ensuring the stability of the workpiece during the clamping process.

[0037] More specifically, the first XZ two-axis transfer mechanism 103 includes an X-guide rail group, a mounting bracket, a driving unit, a clamping jaw bracket and a clamping jaw group 104 .

[0038] In the above structural composition, the X-guide rail group ensures the accuracy of the transfer process, and the mounting bracket is made of high-strength steel to ensure that it does not deform during the transfer process.

[0039] The drive unit adopts a servo motor, which can achieve high-precision positioning and fast movement.

[0040] The clamping jaws group includes a plurality of controlled clamping jaws arranged in the height direction, and these clamping jaws can be adjusted according to the size and shape of the workpiece to adapt to different types of workpieces. The transfer mechanism can accurately grasp and transfer the assembly into the welding assembly 2.

[0041] More specifically, the welding assembly 2 includes a second machine platform 201 , a YZ two-axis material receiving mechanism 202 , at least one high-frequency welding seat 203 and a detection camera 204 .

[0042] In terms of structure, the second machine 201 is made of a steel structure frame like the first machine 101 to ensure the stability and durability of the equipment.

[0043] The YZ two-axis material receiving mechanism 202 includes a Z-direction guide rail, a fixed bracket, a Y-direction guide rod, a Y-direction cylinder and a material receiving clamping claw group.

[0044] The fixed bracket is installed on the Z guide rail and is made of aluminum alloy material, which has the characteristics of light weight and high strength.

[0045] The movable bracket is installed on the fixed bracket through the Y guide rod and the Y cylinder. The material receiving jaw group has a plurality of controlled material receiving jaws 205. These material receiving jaws 205 can accurately clamp the assembly and drive it as a whole to descend into the high-frequency welding seat 203, ensuring the stability of the assembly during the welding process.

[0046] More specifically, the high-frequency welding seat 203 includes a water-cooling base, a heat-resistant welding base and a high-frequency welding ring.

[0047] The water-cooled base is made of copper with good thermal conductivity and is equipped with a circulating coolant system inside, which can effectively dissipate heat and prevent overheating during welding.

[0048] The heat-resistant welding base is made of ceramic material, which has good high temperature resistance and ensures the stability of the welding base in high temperature environment. The high-frequency welding ring is made of highly conductive copper material, which can provide a stable high-frequency electromagnetic field to achieve high-quality welding.

[0049] The welding wire ring is installed around the high-frequency welding seat and is made of high-quality welding materials. It can provide uniform and stable welding current to ensure the firmness and consistency of the welding point.

[0050] In this embodiment, the inspection camera 204 installed above the welding assembly 2 is used to monitor the welding process in real time to ensure the quality of each welding point. The inspection camera 204 adopts a high-resolution design, which can capture subtle welding defects and provide accurate welding quality inspection.

[0051] More specifically, the inspection camera 204 plays a key role in the welding process by capturing every detail of the welding process in real time, accurately observing and recording the welding area, and ensuring that every step in the welding process is carried out within the expected range.

[0052] It should be understood that the detection camera 204 can detect the quality of the welding point, including the uniformity of the welding, the integrity of the welding point, and the fusion of the welding materials. Through image processing technology, the system can analyze the shape of the welding point and determine whether there are welding defects, such as too small welding points, uneven welds, or incomplete welding. If the detection camera 204 finds that the welding quality does not meet the requirements, it will immediately send an alarm signal. The system will automatically identify and mark the defective welding points according to the preset quality standards, and notify the operator to check and handle them. This function ensures the quality of each welding point and reduces the production of unqualified products.

[0053] In addition, in some embodiments, the detection camera 204 is not only used for real-time monitoring and quality inspection, but also can record data in the welding process, including welding parameters, image data and inspection results. These data are saved for subsequent analysis and optimization. Through data analysis, problems and room for improvement in the welding process can be found, thereby continuously improving welding quality and production efficiency. According to the results of visual inspection, the system can automatically adjust welding parameters, such as welding current, welding time and welding position. Through this closed-loop control method, welding parameters can be optimized in real time, ensuring the stability and consistency of the welding process and improving welding quality.

[0054] It should be understood that the above-mentioned visual inspection and data recording work requires the support of software, but the relevant software is widely used in this field and should be regarded as prior art.

[0055] In this embodiment, the blanking assembly 3 includes a third machine platform 301 and a second XZ two-axis transfer mechanism 302. The third machine platform 301 is made of a steel structure frame and has good stability.

[0056] The second XZ two-axis transfer mechanism 302 has the same structure as the first XZ two-axis transfer mechanism 102. The transfer mechanism can grab the welded assembly from the YZ two-axis receiving mechanism 202 and move it to the unloading station to realize automatic unloading.

[0057] The working process of this embodiment is as follows: the loading process is realized by the cooperation of the loading machine 101 and the clamping group. The workpiece is first placed on the working fixture, the electric clamp of the clamping group clamps the workpiece, and then the welding wire ring is manually placed, and the loading machine 102 moves upward to fasten the parts, welding wire and workpiece in the working fixture into an assembly. The first XZ two-axis transfer mechanism 103 grabs the assembly and transfers it to the welding assembly 2. The YZ two-axis receiving mechanism 202 of the welding assembly 2 receives the assembly and brings it into the high-frequency welding seat 203 for welding. During the welding process, the detection camera 204 monitors the welding quality in real time to ensure the firmness of each weld. After welding is completed, the second XZ two-axis transfer mechanism 302 transfers the assembly to the unloading station to realize automatic unloading.

[0058] The automatic high-frequency welding device of this embodiment realizes the fully automated operation from loading, welding to unloading of workpieces through the above-mentioned structural design, thereby improving production efficiency and welding quality.
