Description

Technical Field

[0001] The invention relates to the technical field of automobile parts welding, and in particular to a laser welding device for automobile parts production. Background Art

[0002] In order to ensure the overall beauty and reliability of the car, laser welding is mostly used for the processing of automotive parts. Laser processing is a technology that uses a high-radiation intensity laser beam, focused by an optical system, to apply high temperature to the processing part of the workpiece for thermal processing. Compared with traditional welding methods, laser welding has the characteristics of high production efficiency and easy automatic control, making it very suitable for large-scale production lines and flexible manufacturing. Among them, the successful application of laser welding in the field of engineering vehicle manufacturing can greatly improve production efficiency and product quality, which has highlighted the huge advantages of laser welding.

[0003] The existing laser welding device has the following defects when used:

[0004] First, existing laser welding devices do not have a gas purification function, but the gases commonly used in the welding process include inert gases such as argon and helium. These gases are colorless, odorless, and tasteless at normal temperatures, and have stable chemical properties and are difficult to react chemically with other substances. Although these inert gases themselves are not toxic, during the laser welding process, high temperatures and arcs may produce some harmful gases, such as ozone and nitrogen oxides, which may have a negative impact on the respiratory system, such as causing respiratory inflammation, coughing, dyspnea and other symptoms, thereby causing a certain degree of harm to the physical condition of the workers;

[0005] Second, the working platform on the existing laser welding device has only one processing station, which affects the welding efficiency of automobile parts.

[0006] Therefore, how to provide a laser welding device for automobile parts production with a gas purification function and multiple workstations has become a technical problem to be solved by those skilled in the art. Summary of the invention

[0007] The technical problem to be solved by the present invention is how to provide a laser welding device for automobile parts production with a gas purification function and multiple workstations.

[0008] To achieve the above-mentioned purpose, the present invention provides a laser welding device for automobile parts production, comprising: a shell, a fixing portion for fixing automobile parts is provided on the shell, and a welding portion for performing a welding process on the automobile parts is provided inside the shell, and also includes a filter box, the filter box is provided on one side of the shell, and a gas channel is provided between the filter box and the shell, a filter plate for filtering exhaust gas generated by welding is provided inside the filter box, and an exhaust port for discharging the filtered gas is provided on the top of the filter box.

[0009] The shell is preset with control buttons, warning lights and operation panel. When in use, the fixing part is used to fix the automobile parts, and then the welding part is used to perform laser welding on the automobile parts. The exhaust gas generated during laser welding is sent into the filter box through a preset channel, filtered and purified by the filter plate, and then discharged to the outside from the exhaust port.

[0010] Preferably, the fixing portion includes a support plate and a working platform;

[0011] The support plate is movably arranged on the shell;

[0012] The working platform is arranged on the supporting plate, and two working platforms are symmetrically arranged on the front and rear sides of the supporting plate to form a double-station structure of the A and B sides.

[0013] The design of the support plate provides fixed support for the working platform, and the design of the double workstations improves the welding efficiency of automotive parts.

[0014] Preferably, a supporting plate is provided on the working platform, and a mounting frame is provided on the working platform;

[0015] An electric push rod is arranged on the lower end surface of the mounting frame, and a clamping plate is connected to the output end of the electric push rod;

[0016] An infrared sensor is arranged on one side of the mounting frame close to the supporting plate.

[0017] The support plate is used to place auto parts, and the mounting frame is designed to fix the electric push rod. The electric push rod adopts the existing structure on the market in this field, and is used to drive the splint to move up and down longitudinally, so that the splint can fix and clamp auto parts of different thicknesses, avoiding limitations of the device when in use. The infrared sensor adopts the existing structure on the market in this field, and is used to detect whether the auto parts placed on the support plate are in place.

[0018] Preferably, driving sources are provided on both sides of the working platform.

[0019] The driving source adopts the existing motor structure on the market to drive the working platform to flip up and down, so as to facilitate welding on both sides of the workpiece, thereby ensuring the welding efficiency of automobile parts.

[0020] Preferably, the welding portion is a welding chamber, an opening is preset on the front side of the welding chamber, and the opening is movably connected to a support plate via a bearing.

[0021] The welding process is carried out inside the welding chamber to prevent the exhaust gas generated during welding from drifting around. The movable design of the support plate and the welding chamber makes it convenient for the staff to alternately perform the welding process on the two welding stations above it. A driving source (not shown in the figure) is preset at the connection between the support plate and the welding chamber to form an automated structure. This method is common knowledge known in the art, so it will not be repeated here.

[0022] Preferably, a welding head is arranged inside the welding chamber, and a fixing seat is arranged below the welding head.

[0023] The welding head adopts the existing laser welding head structure on the market, and the welding head is arranged inside the welding chamber through a fixed seat. A maintenance door is preset on the welding chamber close to the fixed seat to facilitate the staff to replace and maintain the welding head later.

[0024] Preferably, a display screen is provided on the front surface of the welding chamber, and the display screen is located above the support plate.

[0025] The display screen adopts the existing LED screen structure on the market. When in use, the display screen is electrically connected to the monocular camera inside the welding chamber, so that the staff can check the welding process inside the welding chamber.

[0026] Preferably, three filter plates are arranged in parallel inside the filter box, and the aperture sizes of the three filter plates decrease gradually from bottom to top.

[0027] The design of the three filter plates with gradually decreasing aperture sizes from bottom to top allows the exhaust gas to be filtered through three steps, thus ensuring the filtering effect of the exhaust gas.

[0028] Preferably, the gas channel comprises a gas output end and a gas input end;

[0029] The gas output end is arranged at the top of the welding chamber;

[0030] The gas input end is arranged at the bottom of the filter box close to the shell side;

[0031] The gas output end and the gas input end are connected via a pipeline.

[0032] When in use, the gas output end and the gas input end are connected through a pipeline to form a gas channel, so that the exhaust gas generated when welding automobile parts inside the welding chamber enters the filter box through the gas channel for filtering and purification.

[0033] Preferably, it also includes a guide plate, which is correspondingly arranged at the top and bottom of the filter box, and the guide plate is connected to the filter box in an inclined manner.

[0034] The inclined design forms a certain diversion angle, thereby guiding the flow of gas inside the filter box, further reflecting the practicality of the device.

[0035] The beneficial effects of the present invention are:

[0036] 1. When the present invention is in use, the welding process of the welding chamber is carried out in a sealed space, and the exhaust gas generated during laser welding is sent into the filter box through a preset channel, and is discharged to the outside from the exhaust port after being filtered and purified by the filter plate. In addition, the filter plates are designed with three apertures that gradually decrease from bottom to top, and the exhaust gas is subjected to three filtering processes, thereby ensuring the filtering effect of the exhaust gas, reflecting the environmental protection and safety of the device when in use, and further promoting its use.

[0037] 2. When the present invention is in use, two sets of working platforms are arranged on the front and rear sides of the support plate to form a double-station structure for the A and B sides. The double-station structure cooperates with the design of the movable support plate to improve the welding efficiency of the workers on automobile parts, reflecting the practicality of the device.
