Description

Technical Field

[0002] With the rapid development of the automobile industry, the welding process and quality of automobile floors, as key load-bearing structural components of automobiles, play a vital role in the overall performance and safety of automobiles. In the traditional automobile floor welding production, it mainly relies on manual operation or semi-automatic equipment, which has many disadvantages. On the one hand, the production efficiency is extremely low and it is difficult to meet the growing market demand; on the other hand, the welding quality is difficult to be effectively guaranteed, and it is easy to have problems such as loose welding and uneven welds. At the same time, traditional welding methods will also produce a large amount of welding debris, which not only affects the working environment, but also may cause harm to the health of operators.

[0003] In recent years, automated welding technology has been widely used in the field of automobile manufacturing. Automated welding can significantly improve welding efficiency and welding quality, and reduce the impact of human factors on the welding process. However, the existing automated welding equipment for automobile floors still has some shortcomings in actual use. For example, an automated welding production line for automobile floors with application number 202011225882.3, although it solves the problem that it is inconvenient to position the base plate during use and the debris generated by welding is ejected far away and difficult to collect, the device is not convenient for cleaning the debris generated on the automobile floor after or during welding. If these debris are not cleaned in time, they may affect subsequent processing procedures and may even have an adverse effect on the quality of the automobile floor. In addition, uncleaned debris may also interfere with the normal operation of the equipment and reduce the service life of the equipment. Therefore, it is of great practical significance to develop an automated welding production equipment for automobile floors that can effectively clean welding debris. Summary of the invention

[0057] like Figure 1-Figure 9 As shown, the present invention provides an automated welding production equipment for automobile floors, aiming to solve the problems of low production efficiency, unstable welding quality and difficulty in cleaning welding debris in traditional welding methods. The equipment includes a workbench 1, a protective shell 2, a cleaning mechanism 3, a fume exhaust mechanism 4 and other auxiliary components.

[0058] The workbench 1 is used as the foundation of the whole device to support and move the car floor. The upper surface of the workbench is provided with rollers 6 and rollers 7 to facilitate the smooth movement of the floor. The workbench 1 is also provided with a filter 11 and a collection box 8 to collect the cleaned welding debris.

[0059] The protective shell 2 is fixed on the workbench 1 to protect the welding process and prevent welding debris from splashing. A welding machine 9 is arranged inside the protective shell to perform welding operations.

[0060] The cleaning mechanism 3 is the core component of the present invention, which is used to clean the debris on the floor after welding. It includes a connecting frame 301, a first electric push rod 302, an inverted L-shaped plate 303, a second electric push rod 304, a mounting shell 305 and other components. Through the extension and retraction of the electric push rod and the drive of the servo motor 309, the cleaning brush 319 can reciprocate and circulate on the floor surface to effectively clean the welding debris.

[0061] The smoke exhaust mechanism 4 includes a smoke exhaust pipe 401, a smoke exhaust fan 402 and a filter element 403, which are used to exhaust the smoke generated during the welding process to protect the working environment and the health of the operators.

[0062] The beneficial effect of this embodiment is that the traditional manual or semi-automatic welding method is replaced by automated equipment, which significantly improves production efficiency and welding quality. At the same time, the special cleaning mechanism 3 is used to effectively clean and collect welding debris, avoid the interference of debris on subsequent processes, and extend the service life of the equipment. Example 2

[0063] like Figure 1-Figure 9 As shown, the present invention provides another optimized automobile floor automated welding production equipment, which is further improved on the basis of Example 1.

[0064] First, a clamping device is added to the workbench 1, including a third electric push rod 13 and a clamping plate 14, which is used to stably fix the car floor during the welding process to ensure the accuracy and quality of the welding.

[0065] Secondly, a smoke exhaust mechanism 4 is added inside the protective shell 2, including a smoke exhaust pipe 401, a smoke exhaust fan 402 and a filter element 403. This improvement is intended to more effectively remove harmful smoke generated during welding, protect the health of operators, and improve the working environment.

[0066] In addition, the cleaning mechanism 3 is also optimized to enhance its cleaning effect and efficiency. Through accurate electric push rod control and the drive of the servo motor 309, the cleaning brush 319 can more accurately clean the welding debris on the floor surface to ensure thoroughness and uniformity of cleaning.

[0067] The beneficial effect of this embodiment is that the stability and safety of welding are further improved by adding the clamping device and the smoke exhaust mechanism 4. At the same time, the optimized cleaning mechanism 3 can clean welding debris more efficiently, reduce the interference of debris on the equipment and subsequent processes, and further improve production efficiency and product quality.

[0068] The overall working principle of the present invention; when in use, first place the car floor to be welded on the workbench 1. Then, use the rollers 6 and rollers 7 on the workbench 1 to easily push the car floor into the interior of the protective shell 2 for welding. The design of the rollers 6 and rollers 7 effectively reduces the friction between the workbench 1 and facilitates the movement of the floor. When the car floor is pushed into the interior of the protective shell 2 and is blocked and limited by the limiting inverted L-shaped plate 16, the third electric push rod 13 will push the clamping plate 14, so that the two sets of clamping plates 14 will steadily push the car floor to the inner top wall of the two clamping inverted U-shaped plates 12, thereby ensuring the stability of the car floor during the welding process. Subsequently, the welding machine 9 performs welding on the fixed car floor. Smoke will be generated during the welding process. At this time, the exhaust mechanism 4 is started, and the exhaust fan 402 rotates to suck the smoke generated by welding into the exhaust pipe 401. After the smoke is purified by the filter element 403, the clean gas is discharged through the exhaust pipe 401, effectively protecting the staff from the harm of welding smoke. After the welding is completed, the fourth electric push rod 15 is started to drive the limited inverted L-shaped plate 16 to move, thereby removing the blocking limit of the car floor. Then, the welded car floor is smoothly moved out of the protective shell 2 by using the roller 6 and the roller 7. Subsequently, the inverted L-shaped plate 303 is moved toward the bottom plate of the car by the push of the first electric push rod 302. When the second electric push rod 304 and the mounting shell 305 reach the position above the car floor, the second electric push rod 304 further pushes the mounting shell 305 downward until the cleaning brush 319 on its bottom surface contacts the upper surface of the car floor. At this time, the servo motor 309 is started, which drives the first rotating shaft 310 and the first pulley 311 to rotate. During the rotation process, the first pulley 311 drives the second pulley 312 to rotate through the first belt 313, thereby driving the second rotating shaft 314 and the deflection block 315 to rotate. The rotation of the deflection block 315 causes the slide plate 308 to reciprocate left and right inside the mounting shell 305. At the same time, the rotation of the first rotating shaft 310 also drives the rotation of the third pulley 316. During the rotation, the third pulley 316 drives the fourth pulley 321 and the third rotating shaft 320 to rotate through the second belt 317. The rotation of the third pulley 316 also drives the connecting sleeve 318 and the cleaning brush 319 to move cyclically for cleaning through the second belt 317. In this way, the cleaning brush 319 not only reciprocates during the cleaning process, but also moves cyclically, thereby effectively cleaning the welding debris on the upper surface of the car floor. The cleaned welding debris is swept onto the workbench 1, then falls into the inside of the workbench through the leakage net 11 on the workbench 1, and is finally collected in the collection box 8. This process completes the collection of welding debris, effectively preventing the adverse effects of welding debris on subsequent processing procedures.
