Technical Field

[0001] The present invention relates to the technical field of automotive component welding equipment, and specifically to an automotive component welding equipment and its usage method. Background Art

[0002] During the automotive manufacturing process, many components need to be welded to ensure the strength and safety of the structure. For example, the basic structure of the vehicle body, including the front beam, rear beam, and side beams, etc., are usually connected by spot welding or arc welding to ensure the rigidity and strength of the vehicle body. In addition, the instrument panel and its brackets need to be welded to ensure the stable installation of the instrument, and the fixed brackets of the seats are connected to the vehicle body by welding to ensure the safety of the seats, etc.

[0003] During the laser welding process, fumes and spatter will be generated. The nitrogen oxides in the fumes will affect the human respiratory tract and may induce respiratory diseases after being inhaled. Moreover, the high-temperature spatter generated during welding can hurt people and cause harm to the staff. Therefore, it is necessary to collect the spatter and fumes to reduce the harm to the human body during the welding process. Summary of the Invention

The transmission long rod is hingedly connected to the L-shaped limiting plate on the side close to the adaptation gear.

[0017] Further, a method for an automobile part welding device is as follows:

[0018] S1: Continuously filter solid particles: The corresponding mounting frame will quickly return under the elastic force of the filtering spring and hit the limiting block. At this time, the mounting frame drives the filter screen to vibrate. The vibration will vibrate the solid particles attached to the filter screen onto the bottom inner wall of the filter box for collection. During continuous welding, the filter screen will continuously vibrate to ensure that the filter screen will not be blocked;

[0019] S2: Stable clamping of welding parts: When the clamping plate moves to face the bottom of the annular collection cover, the trapezoidal limit plate will contact the two L-shaped limit plates, and the L-shaped limit plate will move away from the support plate, and the trapezoidal limit plate will move towards the direction of the bar hollow block. At this time, the bar hollow block will drive the connecting sliders to approach each other, and the corresponding two clamping springs will be compressed and deformed, further clamping the parts between the clamping plates;

[0020] S3: Improve welding efficiency: Since the laser welding time is only a few seconds, the tension sensing hydraulic cylinder will automatically rise after the welding time is over. At this time, the corresponding L-shaped limit plate close to the adaptive gear will move closer to the support plate, and the corresponding connecting long rod will drive the T-shaped slide plate to leave the rectangular rod. At this time, the triangular block is unlocked, and after the bar-shaped adaptive hollow plate contacts the adaptive gear, it will continue to drive the adaptive gear to rotate, thereby realizing automatic welding and improving welding efficiency;

[0021] S4: Treatment of harmful gases in exhaust gas: The T-shaped filter plate will descend from the sodium hydroxide liquid level during the descending process. The sodium hydroxide solution will be squeezed and filtered out when passing through the holes on the T-shaped filter plate. After the rotating block leaves the T-shaped filter plate, the T-shaped filter plate will float up. During the continuous rotation of the rotating block, the T-shaped filter plate will continuously rise and fall to stir the sodium hydroxide and nitrogen oxides discharged into the flue gas to improve the reaction efficiency.

[0022] The present invention has the following beneficial effects:

[0023] (1) An automotive parts welding device of the present invention starts the drive motor during operation. The drive motor drives the rotating shaft to rotate, and the rotating shaft drives several fan blades to rotate. The rotation of the several fan blades generates a suction force. The suction force passes through the exhaust pipe, the filter box, the collection pipe, and the collection annular groove to extract air from the parts being welded. The fumes and spatter generated during welding will enter the annular collection cover and then enter the filter box through the exhaust pipe. The fumes and spatter will pass through the filter screen, and the filter screen will filter out the particles and spatter in the fumes, achieving gas-solid separation. During the long-term filtering process of the filter screen, solid particles will adhere to the filter screen and cause blockage, affecting the filtering effect of the filter screen. When the trapezoidal limiting plate moves and contacts the L-shaped limiting plate, the L-shaped limiting plate will move away from the support plate. At this time, the limiting spring undergoes a tensile deformation. The L-shaped limiting plate will drive the U-shaped round rod to move synchronously, and the U-shaped round rod will drive the mounting frame to move. At this time, the filtering spring undergoes a tensile deformation. After the trapezoidal limiting plate leaves the L-shaped limiting plate, the L-shaped limiting plate will return under the elastic force of the limiting spring. Correspondingly, the mounting frame will quickly return under the elastic force of the filtering spring and hit the limiting block. At this time, the mounting frame and the filter screen will vibrate, and the vibration will shake the solid particles adhering to the filter screen onto the bottom inner wall of the filter box for collection. During continuous welding, the filter screen will continuously vibrate, ensuring that the filter screen will not become blocked, thereby better filtering the particles and spatter in the fumes, enabling more effective treatment of the fumes, and reducing the complexity of fume treatment;

[0024] (2) An automotive parts welding device of the present invention drives the strip-shaped adaptive hollow plate to rotate during the rotation of the rotating shaft. The strip-shaped adaptive hollow plate drives the trapezoidal plate to rotate. The trapezoidal plate will contact the adaptive gear and drive the adaptive gear to rotate during rotation. The adaptive gear drives the transmission rod to rotate. The two transmission rods rotate synchronously under the action of two belts. At this time, several round rods on the belts will also rotate synchronously. Place the parts to be welded between the two clamping plates. At this time, the clamping spring will undergo a compressive deformation to clamp the parts, ensuring the stability during the movement of the clamping plates driving the parts. When the clamping plates move to be directly below the annular collection cover, the trapezoidal limiting plate will contact the two L-shaped limiting plates. The L-shaped limiting plates will move away from the support plate, and the trapezoidal limiting plate will move towards the strip-shaped hollow block. At this time, the strip-shaped hollow block will drive the connecting sliders to approach each other. Correspondingly, the two clamping springs will undergo compressive deformations to further clamp the parts between the clamping plates, ensuring the stability of the parts during welding;

[0025] (3) The present invention provides an automobile parts welding device. When the L-shaped limit plate moves in a direction away from the support plate, it will drive the connecting long rod to move. At this time, the movement of the L-shaped limit plate will generate a pulling force on the transmission long rod. The pulling force will drive the L-shaped sensing rod to descend. The L-shaped sensing rod will act on the annular collection cover to generate a downward force. When the tension sensing hydraulic cylinder senses the pulling force, it will synchronously descend so that the clamped parts are just covered by the annular collection cover. The connecting long rod will also drive the T-shaped slide plate to move in a direction close to the annular collection cover. When the L-shaped limit plate stops moving, the corresponding T-shaped slide plate will move to the top of the rectangular rod. During the continuous rotation of the rotating shaft, the trapezoidal plate will contact the tooth block on the adapting gear. At this time, since the rectangular rod is locked and cannot move, the corresponding triangular block cannot move and is stuck. In the adaptable gear, when the trapezoidal plate contacts the tooth block on the adaptable gear, it will slide into the bar-shaped adaptable hollow plate. At this time, the telescopic spring is compressed and deformed. When the trapezoidal plate leaves the tooth block on the adaptable gear, the trapezoidal plate will pop out again. Since the laser welding time is only a few seconds, the tension sensing hydraulic cylinder will automatically rise after the welding time is over. At this time, the corresponding L-shaped limit plate close to the adaptable gear will move closer to the support plate, and the corresponding connecting long rod will drive the T-shaped slide plate to leave the rectangular rod. At this time, the triangular block is unlocked. Since the elastic force of the telescopic spring is greater than the elastic force of the adaptable spring, when the triangular block is unlocked, the adaptable spring will be compressed when the trapezoidal plate drives the adaptable gear to rotate, which will not affect the normal rotation of the adaptable gear and the normal transmission of parts, thereby realizing automatic welding and improving welding efficiency;

[0026] (4) The present invention relates to an automobile parts welding device. The filtered smoke will enter the smoke box through the exhaust pipe, and then the smoke will be discharged from the smoke box into the sodium hydroxide in the treatment box. Since the T-shaped filter plate is light in material, it will float on the top of the sodium hydroxide. During the rotation of the rotating shaft, it will drive the rotating block to rotate. During the rotation, the rotating block will contact the T-shaped filter plate and cause the T-shaped filter plate to descend. During the descent, the T-shaped filter plate will descend from the sodium hydroxide liquid level. The sodium hydroxide solution will be squeezed and filtered out when passing through the holes on the T-shaped filter plate. After the rotating block leaves the T-shaped filter plate, the T-shaped filter plate will float up. During the continuous rotation of the rotating block, the T-shaped filter plate will continuously rise and fall to contact the sodium hydroxide and the exhaust. The nitrogen oxides in the flue gas are stirred and reacted to improve the reaction efficiency. As the flue gas is continuously input into the treatment box, the air pressure in the treatment box will continue to increase, and the gas generated after the reaction will enter the sealing box and push the T-shaped hollow slider to rise. At this time, the sealing spring is stretched and deformed. When the air outlet on the T-shaped hollow slider leaves the sealing box, the reacted gas will be discharged from the air outlet, thereby discharging the harmless gas that can be discharged and releasing the pressure. When the device is stopped, the sealing spring will return the air outlet to the sealing box under the action of elastic force to seal the sealing box, preventing dust and outside air from entering the treatment box, thereby reducing the performance of sodium hydroxide and reducing its reaction rate with nitrogen oxides.

Detailed implementation mode

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0044] Please refer to Figure 1 - Fig.12 As shown in the figure, the present invention is a welding device for automobile parts, including two support plates 1. A C-shaped plate 2 is fixedly installed on the top of the two support plates 1. A tensile force sensing hydraulic cylinder 3 is fixedly installed on the inner wall of the top of the C-shaped plate 2. The output end of the tensile force sensing hydraulic cylinder 3 is fixedly installed with an annular collection hood 4. It further includes:

[0045] A filtering mechanism 5, the filtering mechanism 5 includes a filter screen 505 and a vibration assembly for driving the filter screen 505 to vibrate, and a transmission assembly for driving the filter screen 505 to transmit;

[0046] The vibration assembly includes a filter box 501 fixedly installed on the outer wall of the right side of the right support plate 1. A collection pipe 502 is fixedly installed on the top of the filter box 501. The top end of the collection pipe 502 penetrates through the right support plate 1. A limiting block 503 is fixedly installed on the bottom inner wall of the filter box 501. A mounting frame 504 is slidably installed in the filter box 501. The mounting frame 504 is fixedly connected to a filter screen 505.

[0047] The transmission assembly includes two filtering springs 506 fixedly installed on the left inner wall of the filter box 501. The right ends of the two filtering springs 506 are both fixedly connected to the mounting frame 504. An exhaust pipe 507 is fixedly installed on the right side of the filter box 501. A U-shaped round rod 508 is fixedly installed on the right side of the mounting frame 504. The right end of the U-shaped round rod 508 extends outside the filter box 501 and is slidably connected to the filter box 501.

[0048] As Figure 3 and Figure 5 shown, two L-shaped limit plates 509 are respectively installed through and slidably on the two support plates 1. On the sides of the two support plates 1 away from each other, limiting springs 510 are respectively fixedly installed. The ends of the two limiting springs 510 away from each other are respectively fixedly connected to the two L-shaped limit plates 509. The top end of the U-shaped round rod 508 is fixedly connected to the right L-shaped limit plate 509. A laser welding head 511 is fixedly installed on the top inner wall of the annular collection cover 4. A collection annular groove 512 is formed in the annular collection cover 4. The collection annular groove 512 communicates with the collection pipe 502.

[0049] When the trapezoidal limit plate 709 moves into contact with the L-shaped limit plate 509, the L-shaped limit plate 509 will move in a direction away from the support plate 1. At this time, the limiting spring 510 undergoes tensile deformation, and the L-shaped limit plate 509 will drive the U-shaped round rod 508 to move synchronously.

[0050] As Figure 6 shown, a driving mechanism 6 is arranged on the right side of the corresponding support plate 1. The driving mechanism 6 includes a smoking air box 601 fixedly installed on the outer wall of the right side of the right support plate 1. A driving motor 602 is fixedly installed on the right side of the smoking air box 601. A rotating shaft 603 is fixedly installed on the output shaft of the driving motor 602. The rotating shaft 603 penetrates through the smoking air box 601 and the two support plates 1 and is rotatably connected to the smoking air box 601 and the two support plates 1. A plurality of fan blades 604 are fixedly installed on the rotating shaft 603. A processing box 605 is fixedly installed between the two support plates 1. The smoking air box 601 communicates with the processing box 605.

[0051] The filtered flue gas will enter the smoking air box 601 through the exhaust pipe 507, and then the flue gas is discharged into the sodium hydroxide in the processing box 605 from the smoking air box 601.

[0052] As Figure 7As shown, a T-shaped filter plate 606 is slidably installed in the processing box 605, and the top of the T-shaped filter plate 606 extends to the outside of the processing box 605. Two sealing boxes 607 are fixedly installed on the top of the processing box 605. Mounting plates 608 are respectively fixedly installed in the two sealing boxes 607. Sealing springs 609 are respectively fixedly installed on the tops of the two mounting plates 608. T-shaped hollow sliders 610 are respectively fixedly installed on the tops of the two sealing springs 609. The two T-shaped hollow sliders 610 are respectively slidably connected to the two sealing boxes 607. A number of air outlet holes 611 are respectively opened on the two T-shaped hollow sliders 610, and a rotating block 612 is fixedly installed on the rotating shaft 603.

[0053] Since the T-shaped filter plate 606 is light in material, it will float on the top of the sodium hydroxide. During the rotation of the rotating shaft 603, the rotating block 612 will be driven to rotate. During the rotation, the rotating block 612 will contact the T-shaped filter plate 606 and cause the T-shaped filter plate 606 to descend. During the descent, the T-shaped filter plate 606 will descend from the sodium hydroxide liquid level. The sodium hydroxide solution will be squeezed and filtered out when passing through the holes on the T-shaped filter plate 606. After the rotating block 612 leaves the T-shaped filter plate 606, the T-shaped filter plate 606 will float up. During the continuous rotation of the rotating block 612, the T-shaped filter plate 606 will continuously rise and fall to stir the sodium hydroxide and the nitrogen oxides discharged into the flue gas to improve the reaction efficiency. When the gas is transported to the treatment box 605, the air pressure in the treatment box 605 will continue to increase, and the gas generated after the reaction will enter the sealing box 607 and push the T-shaped hollow slider 610 to rise. At this time, the sealing spring 609 is stretched and deformed. When the air outlet 611 on the T-shaped hollow slider 610 leaves the sealing box 607, the gas after the reaction will be discharged from the air outlet 611, thereby discharging the harmless gas that can be discharged and releasing the pressure. When the device is stopped, the sealing spring 609 will cause the air outlet 611 to return to the sealing box 607 under the action of elastic force to seal the sealing box 607, thereby preventing dust and outside air from entering the treatment box 605, thereby reducing the performance of sodium hydroxide and reducing its reaction rate with nitrogen oxides.

[0054] like Figure 4 As shown, a conveying mechanism 7 is provided on the two support plates 1, and the conveying mechanism 7 includes a transmission rod 701 rotatably mounted on the two support plates 1, two belts 702 are respectively sleeved on the two transmission rods 701, and a plurality of round rods 703 are respectively passed through and fixedly installed on the two belts 702, and the ends of the plurality of round rods 703 that are away from each other extend into the two support plates 1 respectively and are slidably connected to the two support plates 1 respectively.

[0055] The transmission rods 701 are caused to rotate synchronously by the two belts 702 , and at this time, the plurality of round rods 703 on the belts 702 also rotate synchronously.

[0056] like Fig. 9 As shown in the figure, a number of clamping components are respectively arranged on two belts 702. The clamping component includes a strip-shaped hollow block 704 fixedly installed on the two belts 702. A limiting round rod 705 is fixedly installed inside the strip-shaped hollow block 704. Two clamping plates 706 and a connecting slider 707 are slidably sleeved on the limiting round rod 705. The clamping plates 706 and the connecting slider 707 are grouped in pairs. Two clamping springs 708 are sleeved on the limiting round rod 705. The two clamping springs 708 are respectively fixedly connected to the two groups of clamping plates 706 and the connecting slider 707. Trapezoidal limiting plates 709 are respectively fixedly installed at the mutually remote ends of the two connecting sliders 707. The mutually remote ends of the two trapezoidal limiting plates 709 both extend outside the strip-shaped hollow block 704 and are both slidably connected to the strip-shaped hollow block 704.

[0057] Place the parts to be welded between the two clamping plates 706. At this time, the clamping springs 708 will undergo compressive deformation to clamp the parts and ensure the stability during the movement of the clamping plates 706 driving the parts.

[0058] As Fig.11 shown in the figure, an adaptation mechanism 8 is arranged on the transmission rod 701. The adaptation mechanism 8 includes an adaptation gear 801 fixedly sleeved on the transmission rod 701. A rectangular plate 802 is fixedly installed on the left side of the corresponding support plate 1. A rectangular rod 803 is slidably installed through the rectangular plate 802. A triangular block 804 is fixedly installed at the bottom of the rectangular rod 803. The triangular block 804 meshes with the adaptation gear 801. An adaptation spring 805 is sleeved on the rectangular rod 803. The bottom end of the adaptation spring 805 is fixedly connected to the triangular block 804. The top end of the triangular block 804 is fixedly connected to the rectangular plate 802.

[0059] Since the rectangular rod 803 is locked and cannot move, the corresponding triangular block 804 cannot move and gets stuck in the adaptation gear 801.

[0060] As Fig.10 and Fig.11 shown in the figure, a strip-shaped adaptation hollow plate 806 is fixedly installed on the rotating shaft 603. A telescopic spring 807 is fixedly installed on the top inner wall of the strip-shaped adaptation hollow plate 806. A trapezoidal plate 808 is fixedly installed at the bottom end of the telescopic spring 807. The bottom end of the trapezoidal plate 808 slidably extends outside the strip-shaped adaptation hollow plate 806. A T-shaped sliding plate 809 is slidably installed through the corresponding support plate 1. A connecting long rod 810 is hingedly installed at the top of the T-shaped sliding plate 809. The end of the connecting long rod 810 is hinged to the L-shaped limiting plate 509 on the side close to the adaptation gear 801. An L-shaped induction rod 811 is fixedly installed on the outer wall of the annular collection cover 4. The left end of the L-shaped induction rod 811 extends outside the U-shaped plate 2 and is slidably connected to the U-shaped plate 2. A transmission long rod 812 is hingedly installed at the bottom end of the L-shaped induction rod 811. The transmission long rod 812 is hinged to the L-shaped limiting plate 509 on the side close to the adaptation gear 801.

[0061] When the trapezoidal plate 808 contacts the tooth block on the adaptive gear 801, it will slide into the bar-shaped adaptive hollow plate 806. At this time, the telescopic spring 807 is compressed and deformed. When the trapezoidal plate 808 leaves the tooth block on the adaptive gear 801, the trapezoidal plate 808 will pop out again. Since the laser welding time is only a few seconds, the tension sensing hydraulic cylinder 3 will automatically rise after the welding time is over. At this time, the corresponding L-shaped limit plate 509 close to the adaptive gear 801 will approach the support plate 1, and the corresponding connecting long rod 810 will drive the T-shaped slide plate 809 to leave the rectangular rod 803. At this time, the triangular block 804 is unlocked, and after the bar-shaped adaptive hollow plate 806 contacts the adaptive gear 801, it will continue to drive the adaptive gear 801 to rotate, thereby realizing automatic welding and improving welding efficiency.

[0062] like Figure 1 - Fig.12 As shown, a method for welding automobile parts equipment, the method steps are as follows:

[0063] S1: Continuously filter solid particles: The corresponding mounting frame 504 will quickly return and hit the limit block 503 under the elastic force of the filter spring 506. At this time, the mounting frame 504 and the filter screen 505 will vibrate. The vibration will shake the solid particles attached to the filter screen 505 to the bottom inner wall of the filter box 501 for collection. During the continuous welding process, the filter screen 505 will continue to vibrate to ensure that the filter screen 505 will not be blocked;

[0064] S2: Stably clamp the welding parts: When the clamping plate 706 moves to face the bottom of the annular collection cover 4, the trapezoidal limit plate 709 will contact the two L-shaped limit plates 509, and the L-shaped limit plate 509 will move away from the support plate 1, and the trapezoidal limit plate 709 will move towards the direction close to the bar hollow block 704. At this time, the bar hollow block 704 will drive the connecting slider 707 to approach each other, and the corresponding two clamping springs 708 will be compressed and deformed, further clamping the parts between the clamping plates 706;

[0065] S3: Improve welding efficiency: Since the laser welding time is only a few seconds, the tension sensing hydraulic cylinder 3 will automatically rise after the welding time is over. At this time, the corresponding L-shaped limit plate 509 close to the adaptive gear 801 will move closer to the support plate 1, and the corresponding connecting long rod 810 will drive the T-shaped slide plate 809 to leave the rectangular rod 803. At this time, the triangular block 804 is unlocked, and after the bar-shaped adaptive hollow plate 806 contacts the adaptive gear 801, it will continue to drive the adaptive gear 801 to rotate, thereby realizing automatic welding and improving welding efficiency;

[0066] S4: Treatment of harmful gases in exhaust gas: The T-shaped filter plate 606 will descend from the sodium hydroxide liquid level during the descending process, and the sodium hydroxide solution will be squeezed and filtered out when passing through the holes on the T-shaped filter plate 606. After the rotating block 612 leaves the T-shaped filter plate 606, the T-shaped filter plate 606 will float up. During the continuous rotation of the rotating block 612, the T-shaped filter plate 606 will continuously rise and fall to stir the sodium hydroxide and the nitrogen oxides discharged into the flue gas to improve the reaction efficiency.
