Description

Technical Field

[0001] The invention relates to the technical field of laser welding equipment, in particular to a laser welding system for metal parts in the manufacture of vehicle lamps. Background Art

[0002] In recent years, as automobile OEMs have increasingly stringent requirements for headlight styling, laser welding technology has gradually emerged in the manufacturing of headlights. Its unique weld aesthetics, welding flexibility and high strength make laser welding a leader in the field of headlight welding.

[0003] During the laser welding process, two parts are tightly joined under controlled pressure. The laser beam is precisely focused on the area to be welded through a set of optical paths consisting of reflectors, lenses or optical fibers. The laser energy penetrates the transmissive material above and is absorbed by the absorbing material below, which is then converted into heat energy. As the temperature of the lower material rises, the heat is transferred to the upper material, forming a molten weld zone at the contact interface between the two. Subsequently, the molten material quickly solidifies to form a strong joint, thus firmly connecting the two together.

[0004] The essence of laser welding is to melt the joints of equipment through high-intensity laser energy. However, there are some small metal parts on the headlights, which are not so easy to position accurately during welding, which can easily affect the welding accuracy.

[0022] Working principle: When the staff uses laser welding to process the parts of the headlights, the staff first opens the closed cover on the base. After the closed cover on the base is opened, the staff overlaps the headlight parts to be welded and places them on the positioning seat. Then the staff resets and closes the closed cover on the base, and then the subsequent laser welding of the headlights can be started; first, the component positioning mechanism is started, and the driving motor 2 in the positioning seat is started. The shaft of the driving motor 2 drives the driving disk and the limit stabilizing seat thereon to rotate synchronously. While the driving disk rotates, it also drives the spiral track thereon to rotate synchronously. The spiral track rotates, and the spiral track also rotates synchronously in the arc groove 2 on the bottom base of the step fixing seat. As the spiral track on the driving disk rotates, the driving disk drives the step fixing seat to move synchronously toward the middle in the moving groove of the positioning seat. As the step fixing seat in the moving groove moves synchronously toward the middle, the lamp parts on the positioning seat are also pushed to move toward the middle during the movement of the step fixing seat. After the step fixing seat pushes the lamp parts on the positioning seat to the center position on the positioning seat, the step fixing seat stops moving, thereby completing the center positioning and fixing of the lamp parts on the positioning seat. The step fixing seat stops moving in the moving groove on the positioning seat after the step fixing seat has positioned and fixed the center of the headlight part on the positioning seat. At this time, the electromagnet seat 1 in the inner cavity is energized, thereby changing the magnetism of the electromagnet seat 1 and the electromagnet seat 2, so that the magnetism of the electromagnet seat 1 and the socket are the same, and the magnetism of the electromagnet seat 2 and the socket are opposite. Through the principle that like magnets repel each other and opposite magnets attract each other, the same repulsion force generated between the electromagnet seat 1 and the socket causes the socket in the inner cavity to slide down into the bottom cavity on the driving disk, and is adsorbed and fixed by the magnetic attraction between the electromagnet seat 2 in the bottom cavity and the socket, thereby The driving disk is locked after positioning, so as to improve the fixing stability of the headlight parts after positioning; then the welding mechanism is adjusted to start, and the driving motor 1 in the installation chamber is started, and the rotating shaft of the driving motor 1 drives the rotating seat in the processing chamber to rotate synchronously while rotating, and the rotating seat drives the positioning seat at the bottom thereof and the headlight parts that are positioned and fixed to rotate while rotating, and then as the headlight parts rotate, the laser welding arm in the processing chamber is started, and at the same time, the connection between the headlight parts that are fixed and positioned on the positioning seat is laser welded, so as to complete the welding processing in the headlight manufacturing process;At the same time, the fume purification mechanism is started. During the laser welding of the headlight parts, the fan is started. The fan conveys the fume displayed in the processing chamber during the laser welding process to the processing box through the connecting pipe. Then, the harmful fume entering the processing box first passes through the activated carbon filter plate to adsorb and decompose the harmful substances contained in it. Then, the fume after purification by multiple activated carbon filter plates passes through the filter cotton plate again to filter the suspended particles in the air. Finally, the air after multiple purification treatments is discharged through the discharge slot at the bottom of the processing box, thereby completing the purification of the fume during the laser welding process. After that, The product inspection mechanism is started, and the main hydraulic cylinder in the base is started first. The rod of the main hydraulic cylinder is pushed out, and the rod on the main hydraulic cylinder is pushed out while driving the sealing cover at the bottom to move down synchronously. As the sealing cover moves down, the sealing cover covers the laser-welded headlights on the rotating seat, and as the rod of the main hydraulic cylinder is continuously pressed down, the silicone sealing strip at the bottom of the sealing cover is deformed under pressure, thereby filling and sealing the inside of the sealing cover. After that, the helium generator on the sealing cover injects helium into the sealing cover, and after the sealing cover is filled with helium, the pressure in the sealing cover is maintained for a certain period of time. At the same time, the staff can use the pressure gauge on the sealing cover to check it. The internal pressure maintenance situation is checked. If the pressure display index in the sealing cover does not change after a certain period of time, the welding seal at the welding position of the headlight parts is good. If the pressure display index in the sealing cover changes after a certain period of time, there are welding defects at the welding position of the headlight parts. Then the electric push rod in the processing chamber is started, and the rod body on the electric push rod is pushed out. While the electric push rod body is pushed out, it drives the mounting seat on it to move synchronously toward the position of the headlight welded by the laser in the middle. While the mounting seat moves, it drives the sonic vibrator and the sonic resonance frequency receiver on it to move synchronously. Until the sonic vibrator on the mounting seat and the laser welder are After the surfaces of the connected lamp components are in contact, the acoustic vibrator is started and vibrates, applying acoustic excitation to the lamp surface, and the acoustic resonance frequency receiver in the mounting seat receives the resonance frequency generated in the lamp component and transmits it to the information receiving processor, which analyzes and processes the received resonance frequency and the frequency of the lamp in the normal state, so as to detect and measure the welding integrity and welding sealing of the lamp; after the inspection is completed, the qualified lamps are removed and packaged by the staff, and the unqualified lamps are collected by the staff, and then re-welded or disassembled. ;

[0023] The present invention provides an intelligent welding system for manufacturing vehicle lamps, which has the following beneficial effects:

[0024] 1. The present invention increases and sets a component positioning mechanism. When laser welding is performed on the parts of the headlights, on the one hand, the stability of the laser welding process of the headlights can be improved to avoid problems such as welding offset. On the other hand, the accuracy of the welding position of the headlight parts can be ensured, thereby making the qualified rate of the headlight products after the welding process higher.

[0025] 2. The present invention increases and sets an adjusting welding mechanism, and adopts automatic angle adjustment and laser welding to the lamp parts after positioning and fixing. This can not only ensure the uniformity of welding between the lamp parts, but also this automated welding process can reduce the labor intensity of the staff and improve the automation and intelligence of the welding process.

[0026] 3. The present invention adds and sets a fume purification mechanism to perform multiple purification and filtration treatments on the fume generated during the laser welding process. First, the harmful substances contained in the fume can be adsorbed and purified, thereby reducing the harmful substance components in the air. Secondly, harmful substances such as particulate matter remaining in the fume can be filtered, thereby avoiding pollution and harm to the surrounding environment caused by direct emission of fume.

[0027] 4. The present invention increases and sets a finished product detection mechanism. On the one hand, the air tightness of the welding position of the headlight is detected by helium, thereby ensuring the sealing of the welding position of the headlight and preventing the headlight from leaking or taking in air during use. On the other hand, the headlight is detected as a whole by means of acoustic wave excitation. Through this dual detection method, the accuracy and efficiency of the detection after the headlight is welded are guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] Please see attached Figure 1 - Attachment Figure 3The embodiment of the present invention provides an intelligent welding system for manufacturing a vehicle lamp, comprising a base 1, which is used as a basic component of the whole device and is used to carry and assemble various processing mechanisms and their structural parts thereon; a processing chamber 8, which is arranged inside the base 1 and is used for laser welding processing of vehicle lamp parts; a sealing cover 3, which is arranged on the base 1 and is used for protecting the vehicle lamp parts in the processing chamber 8 during laser welding; an inspection cabinet door 6, which is arranged on both sides of the bottom of the front end of the base 1 and is used for daily inspection and maintenance of the whole device;

[0043] Please see attached Figure 4 - Attachment Figure 8 , a component positioning mechanism, which is arranged at the middle of the bottom end of the processing chamber 8, and is used to position the lamp parts required for laser welding;

[0044] The component positioning mechanism includes a positioning seat 14, a driving disk 28 is rotatably connected to the middle and upper inner side of the positioning seat 14, a limited position stabilizing seat 34 is fixedly connected to the middle of the outer wall of the driving disk 28, a driving motor 2 33 is fixedly connected to the middle of the inner bottom end of the positioning seat 14, an output end of the driving motor 23 is fixedly connected to the middle of the driving disk 28, and a spiral track 32 is arranged at the top of the driving disk 28.

[0045] When the component positioning mechanism is started, the driving motor 2 33 in the positioning seat 14 is started, and the rotating shaft of the driving motor 2 33 drives the driving disk 28 and the limiting stabilizing seat 34 thereon to rotate synchronously. While the driving disk 28 rotates, it also drives the spiral track 32 thereon to rotate synchronously. While the spiral track 32 rotates, it also causes the spiral track 32 to rotate synchronously in the arc groove 27 on the bottom base of the step fixing seat 11.

[0046] As the spiral track 32 on the driving disk 28 rotates, the driving disk 28 drives the stepped fixing seat 11 to move synchronously toward the middle in the moving groove 12 of the positioning seat 14. As the stepped fixing seat 11 in the moving groove 12 moves synchronously toward the middle, the step fixing seat 11 also synchronously pushes the car light parts on the positioning seat 14 to move toward the middle during the movement of the step fixing seat 11. After the stepped fixing seat 11 pushes the car light parts on the positioning seat 14 to the center position on the positioning seat 14, the stepped fixing seat 11 stops moving, thereby completing the center positioning and fixation of the car light parts on the positioning seat 14.

[0049] After the stepped fixing seat 11 has positioned and fixed the center of the headlight part on the positioning seat 14, the stepped fixing seat 11 stops moving in the moving groove 12 on the positioning seat 14. At this time, the electromagnet seat 1 29 in the inner cavity 30 is energized, thereby changing the magnetism of the electromagnet seat 1 29 and the electromagnet seat 2 35, so that the magnetism of the electromagnet seat 1 29 and the socket 31 are the same, and the magnetism of the electromagnet seat 2 35 and the socket 31 are opposite. Through the principle that like magnets repel each other and opposite magnets attract each other, the like repulsive force generated between the electromagnet seat 1 29 and the socket 31 causes the socket 31 in the inner cavity 30 to slide down into the bottom cavity 36 on the driving disk 28, and is adsorbed and fixed by the magnetic attraction between the electromagnet seat 2 35 and the socket 31 in the bottom cavity 36, so that the driving disk 28 after positioning is locked again, thereby improving the fixing stability of the headlight part after positioning.
