[0001] The present invention relates to the technical field of automobile component welding equipment, in particular to an automobile component welding equipment and a use method thereof. Background Art

[0002] During the automobile manufacturing process, many parts need to be welded to ensure the strength and safety of the structure. For example, the basic structure of the car body, including the front beam, rear beam and side beam, etc., are usually connected by spot welding or arc welding to ensure the rigidity and strength of the car body. In addition, the dashboard and its brackets need to be welded to ensure the stable installation of the instrument, and the fixed bracket of the seat is connected to the car body by welding to ensure the safety of the seat, etc.

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

[0004] The purpose of the present invention is to provide an automobile parts welding device and a method for using the same, so as to solve the problem of smoke and spatter generated during laser welding.

[0014] Further, a number of clamping components are respectively arranged on the two belts. The clamping component includes a strip-shaped hollow block fixedly installed on the two belts.

The clamping plates and the connecting slider are in pairs. Two clamping springs are sleeved on the limiting round rod. The two clamping springs are respectively fixedly connected to the two groups of clamping plates and the connecting slider.

[0016] Further, a strip-shaped adaptation hollow plate is fixedly installed on the rotating shaft.

A T-shaped sliding plate is slidably installed through the corresponding support plate. A connecting long rod is hingedly installed at the top of the T-shaped sliding plate. The end of the connecting long rod is hingedly connected to the L-shaped limiting plate on the side close to the adaptation gear.

The left end of the L-shaped induction rod extends outside the U-shaped plate and is slidably connected to the U-shaped plate. The bottom end of the L-shaped induction rod is hingedly installed with a transmission long rod. 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 parts 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 the continuous welding process, the filter screen will continuously vibrate to ensure that the filter screen will not be blocked;

[0019] S2: Stably clamp the welding parts: When the clamping plate moves to be directly below the annular collection hood, the trapezoidal limit plate will contact the two L-shaped limit plates. The L-shaped limit plates will move away from the support plate, and the trapezoidal limit 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, and the corresponding two clamping springs will undergo compressive deformation to further clamp the parts between the clamping plates.

[0020] S3: Improve the welding efficiency: Since the laser welding time is only a few seconds, after the welding time ends, the tensile induction hydraulic cylinder will automatically rise. At this time, the corresponding L-shaped limit plate close to the adaptation gear will approach the support plate, and the corresponding connecting long rod will drive the T-shaped slide plate away from the rectangular rod. At this time, the triangular block is unlocked. After the strip-shaped adaptation hollow plate contacts the adaptation gear, it will continue to drive the adaptation gear to rotate, thus realizing automatic welding and improving the welding efficiency.

[0021] S4: Treat harmful gases in the waste gas: During the descent of the T-shaped filter plate, it will descend from the sodium hydroxide liquid level. When the sodium hydroxide solution passes through the holes on the T-shaped filter plate, it will be squeezed out. After the rotating block leaves the T-shaped filter plate, the T-shaped filter plate will float. During the continuous rotation of the rotating block, the T-shaped filter plate will continuously rise and fall to stir and react with sodium hydroxide and nitrogen oxides in the discharged flue gas, improving the reaction efficiency.

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

[0023] (1) A welding device for automotive parts of the present invention, when in operation, starts the drive motor. The drive motor drives the rotating shaft to rotate, and the rotating shaft drives several fan blades to rotate. The rotation of 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. The filter screen will filter out the particles and spatter in the fumes, achieving gas-solid separation. During the long-term filtration process of the filter screen, solid particles will adhere to the filter screen, causing blockage and affecting the filtration effect of the filter screen. When the trapezoidal limit plate moves and contacts the L-shaped limit plate, the L-shaped limit plate will move away from the support plate. At this time, the limit spring undergoes a tensile deformation. The L-shaped limit 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 filter spring undergoes a tensile deformation. After the trapezoidal limit plate leaves the L-shaped limit plate, the L-shaped limit plate will return under the elastic force of the limit spring. Correspondingly, the mounting frame will quickly return under the elastic force of the filter spring and hit the limit block. At this time, the mounting frame and the filter screen driven by it will vibrate. 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 vibrate continuously, ensuring that the filter screen will not be 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) A welding device for automotive parts of the present invention, during the rotation of the rotating shaft, it will drive the strip-shaped adaptable hollow plate to rotate. The strip-shaped adaptable hollow plate will drive the trapezoidal plate to rotate. The trapezoidal plate will contact the adaptable gear and drive the adaptable gear to rotate during rotation. The adaptable gear will drive the transmission rod to rotate. The transmission rod makes 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 limit plate will contact the two L-shaped limit plates. The L-shaped limit plates will move away from the support plate, and the trapezoidal limit 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) For a welding device for automotive parts of the present invention, when the L-shaped limit plate moves 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, and the pulling force will drive the L-shaped induction rod to descend. The L-shaped induction rod will act on the annular collection cover to generate a downward force. When the pulling force induction hydraulic cylinder senses the pulling force, it will descend synchronously, so that the clamped part is exactly covered by the annular collection cover. The connecting long rod will also drive the T-shaped slide plate to move towards the annular collection cover. When the L-shaped limit plate stops moving, the corresponding T-shaped slide plate will move above the rectangular rod. During the continuous rotation of the rotating shaft, the trapezoidal plate will contact the tooth block on the adaptive gear. At this time, since the rectangular rod is locked and cannot move, the corresponding triangular block cannot move and gets stuck in the adaptive gear. When the trapezoidal plate contacts the tooth block on the adaptive gear, it will slide into the strip-shaped adaptive hollow plate. At this time, the telescopic spring undergoes compressive deformation. When the trapezoidal plate leaves the tooth block on the adaptive gear, the trapezoidal plate will pop out again. Since the laser welding time is only a few seconds, after the welding time ends, the pulling force induction hydraulic cylinder will automatically rise. At this time, the corresponding L-shaped limit plate close to the adaptive gear will move towards the support plate, and the corresponding connecting long rod will drive the T-shaped slide plate away from 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 adaptive spring, when the triangular block is unlocked, the adaptive spring will be compressed when the trapezoidal plate drives the adaptive gear to rotate, thus not affecting the normal rotation of the adaptive gear and the normal transmission of parts, thereby realizing automatic welding and improving the welding efficiency;

[0026] (4) For a welding device for automotive parts of the present invention, the filtered flue gas will enter the smoking air box through the exhaust pipe, and then the flue gas will be discharged from the smoking air box into the sodium hydroxide in the treatment box. Since the T-shaped filter plate is made of a light material and floats on the top of the sodium hydroxide, during the rotation of the rotating shaft, it will drive the rotating block to rotate. The rotating block will contact the T-shaped filter plate during rotation and cause the T-shaped filter plate to descend. During the descent of the T-shaped filter plate, it will descend from the sodium hydroxide liquid level. When the sodium hydroxide solution passes through the holes on the T-shaped filter plate, it will be squeezed and filtered out. 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 and react the sodium hydroxide and nitrogen oxides in the discharged flue gas, improving the reaction efficiency. Since the flue gas is continuously input into the treatment box, the air pressure in the treatment box will continuously increase. The gas generated after the reaction will enter the sealed box and push the T-shaped hollow slider to rise. At this time, the sealing spring undergoes tensile deformation. When the air outlet hole on the T-shaped hollow slider leaves the sealed box, the reacted gas will be discharged from the air outlet hole, thereby discharging and releasing the pressure of the harmless gas that can be discharged. When the device stops running, the sealing spring will, under the action of the elastic force, make the air outlet hole return to the sealed box to seal the sealed box, preventing dust and external air from entering the treatment box, thereby reducing the performance of the sodium hydroxide and reducing its reaction rate with nitrogen oxides.

Specific 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 efforts shall fall within the protection scope of the present invention.

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

[0045] A filtering mechanism 5, the filtering mechanism 5 includes a filter screen 505 and a vibration component for driving the filter screen 505 to vibrate, and a transmission component 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. An installation frame 504 is slidably installed in the filter box 501, and the installation 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 fixedly connected to the installation 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 installation 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, and 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 provided 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, and 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 treatment box 605. The top end of the T-shaped filter plate 606 extends outside the treatment box 605. Two sealing boxes 607 are fixedly installed on the top of the treatment box 605. Installation plates 608 are respectively and fixedly installed in the two sealing boxes 607. Sealing springs 609 are respectively and fixedly installed on the tops of the two installation plates 608. The top ends of the two sealing springs 609 are respectively and fixedly installed with T-shaped hollow sliders 610. The two T-shaped hollow sliders 610 are respectively slidably connected with the two sealing boxes 607. A number of air outlet holes 611 are respectively opened on the two T-shaped hollow sliders 610. A rotating block 612 is fixedly installed on the rotating shaft 603.

[0053] Since the T-shaped filter plate 606 is made of a relatively light material and will float on the top of sodium hydroxide, during the rotation of the rotating shaft 603, the rotating block 612 will be driven to rotate. The rotating block 612 will contact the T-shaped filter plate 606 during rotation and cause the T-shaped filter plate 606 to descend. During the descent of the T-shaped filter plate 606, it will descend from the sodium hydroxide liquid level. When the sodium hydroxide solution passes through the holes on the T-shaped filter plate 606, it will be squeezed and filtered out. 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 and react sodium hydroxide and nitrogen oxides in the discharged flue gas, improving the reaction efficiency. Due to the continuous input of flue gas into the treatment box 605, the air pressure in the treatment box 605 will continuously increase. 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 undergoes a tensile deformation. When the air outlet holes 611 on the T-shaped hollow slider 610 leave the sealing box 607, the reacted gas will be discharged from the air outlet holes 611, thereby discharging and relieving pressure of the harmless gas that can be discharged. When the device stops running, the sealing spring 609 will, under the action of elastic force, make the air outlet holes 611 return to the sealing box 607 to seal the sealing box 607, preventing dust and external air from entering the treatment box 605, thereby reducing the performance of sodium hydroxide and decreasing its reaction rate with nitrogen oxides.

[0054] As Figure 4 As shown, a conveying mechanism 7 is arranged on the two support plates 1. The conveying mechanism 7 includes a transmission rod 701 rotatably installed on the two support plates 1. Two belts 702 are respectively sleeved on the two transmission rods 701. A number of round rods 703 are respectively and fixedly installed through the two belts 702. The mutually remote ends of the number of round rods 703 respectively extend into the two support plates 1 and are respectively slidably connected with the two support plates 1.

[0055] The transmission rod 701 makes the two transmission rods 701 rotate synchronously under the action of the two belts 702. At this time, the number of round rods 703 on the belts 702 will also rotate synchronously.

[0056] AsFigure 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, ensuring the stability during the movement of the parts driven by the clamping plates 706.

[0058] As Figure 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 Figure 10 and Figure 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. The bottom end of the telescopic spring 807 is fixedly installed with a trapezoidal plate 808. 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 80%. 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. The bottom end of the L-shaped induction rod 811 is hingedly installed with a transmission long rod 812. 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 strip-shaped adaptive hollow plate 806. At this time, the telescopic spring 807 will undergo compressive deformation. 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, after the welding time ends, the tensile force sensing hydraulic cylinder 3 will automatically rise. At this time, the corresponding L-shaped limiting 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 sliding plate 809 away from the rectangular rod 803. At this time, the triangular block 804 is unlocked. After the strip-shaped adaptive hollow plate 806 contacts the adaptive gear 801, it will continue to drive the adaptive gear 801 to rotate, thus realizing automatic welding and improving the welding efficiency.

[0062] As Figure 1 - Figure 12 shown, a method for a welding device of automotive parts has the following method steps:

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

[0064] S2: Stably clamp welding parts: When the clamping plate 706 moves to be directly below the annular collection cover 4, the trapezoidal limiting plate 709 will contact the two L-shaped limiting plates 509. The L-shaped limiting plates 509 will move away from the support plate 1, and the trapezoidal limiting plate 709 will move closer to the strip-shaped hollow block 704. At this time, the strip-shaped hollow block 704 will drive the connecting sliders 707 to move closer to each other, and the corresponding two clamping springs 708 will undergo compressive deformation to further clamp the parts between the clamping plates 706;

[0065] S3: Improve the welding efficiency: Since the laser welding time is only a few seconds, after the welding time ends, the tensile force sensing hydraulic cylinder 3 will automatically rise. At this time, the corresponding L-shaped limiting 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 sliding plate 809 away from the rectangular rod 803. At this time, the triangular block 804 is unlocked. After the strip-shaped adaptive hollow plate 806 contacts the adaptive gear 801, it will continue to drive the adaptive gear 801 to rotate, thus realizing automatic welding and improving the welding efficiency;

[0066] S4: Treat harmful gases in the waste gas: During the downward movement of the T-shaped filter plate 606, it will descend from the sodium hydroxide liquid level. When the sodium hydroxide solution passes through the holes on the T-shaped filter plate 606, it will be squeezed and filtered out. After the rotating block 612 leaves the T-shaped filter plate 606, the T-shaped filter plate 606 will float upward. During the continuous rotation of the rotating block 612, the T-shaped filter plate 606 will continuously rise and fall to stir and react with sodium hydroxide and nitrogen oxides in the discharged flue gas, improving the reaction efficiency.
