Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an intelligent welding robot for metal sheets. Background Technology

[0002] Traditional metal sheet welding relies heavily on manual operation, which results in unstable welding quality, low production efficiency, high labor intensity, and high skill requirements for workers. In order to improve the level of automation, the technology has gradually developed from the initial simple manual welding gun to semi-automatic devices such as track welding.

[0003] Patent publication number CN105458578B relates to a gutter funnel welding device, characterized by comprising a box welding device, a short pipe welding device, and a box-to-short pipe welding device. The gutter funnel welding device provided by this patent has a high degree of automation, can replace manual welding processes involving transmission, reduces labor intensity, greatly improves welding efficiency, has high welding stability, and produces high-quality gutter funnels with a long service life. It avoids the significant hazards to workers associated with manual welding, ensuring worker safety.

[0004] However, existing plate welding equipment usually lacks a mechanism for simultaneously clamping multiple plates and the necessary protective mechanism to prevent welding before clamping is complete. This can easily lead to unstable plate fixation or welding before the plate is clamped due to operator negligence. This can easily result in inaccurate welding position and product damage due to plate displacement or operator negligence, causing material waste and product quality defects.

[0014] (III) Beneficial Effects This invention provides an intelligent welding robot for metal sheets. It has the following advantages: (1) This invention drives the moving screw block to move by driving the lead screw, so that the first connecting rod pushes the clamping arm to clamp the plate, thereby realizing the function of fixing two plates at the same time, ensuring that the plates will not move during welding, effectively preventing inaccurate welding position caused by plate displacement, and avoiding product scrapping and material waste.

[0015] (2) This invention, by moving the screw block to drive the right push rod to push the first push rod, causes the second push rod to push the inclined block down, and releases the limit pin from the welding gun holder, thus achieving the safety protection that two steps must be completed before welding, ensuring that both plates must be clamped before work can begin, effectively preventing workers from welding only one plate due to negligence, and avoiding waste of materials due to damaged products.

[0016] (3) This invention uses a moving screw block to drive the left push rod to push the slide plate, so that the push plate pushes the two plates tightly together, thereby eliminating the gap between the plates and ensuring that the plates are tightly attached during welding. This effectively prevents the problem of weak welding caused by gaps between the plates and avoids quality problems such as false welding and false welding.

[0017] (4) This invention drives the rack to rotate the first gear through the right push rod, which drives the screw to move the rust removal scraper up and down to scrape the plate. At the same time, the sealed piston compresses air to blow away the rust, realizing the function of automatically cleaning the welding surface, ensuring that the welding position is clean and rust-free, effectively preventing the problem of weak welding caused by rust and dust, and improving the welding quality.

[0018] (5) This invention uses the second elastic telescopic rod to push the limit pin, which releases the first elastic telescopic rod from its restriction and causes the unloading plate to flip automatically. This achieves the function of automatic unloading after welding, ensuring that the welded plate can slide out automatically, effectively preventing the risk of workers being burned when picking up materials, and improving work efficiency.

[0019] (6) This invention uses an inclined panel to push the top block up, which, together with the rotation of the rollers and the buffer seat, achieves the functions of smooth material receiving and automatic stacking, ensuring that the board will not be broken when it slides down, effectively preventing collision damage to the board during the collection process, while reducing the labor intensity of workers and making it convenient to use.

The movement of the second push rod 609 presses against the inclined surface block 612, causing the inclined surface block 612 to move downward. The movement of the inclined surface block 612 drives the limiting pin 611 to move downward. The limiting pin 611 moves away from the first hole and the second hole, releasing the limitation of the welding gun holder 701, allowing the welding gun holder 701 to move to the welding position for welding. This achieves the effect that welding can only be carried out after the two plates to be welded are clamped at the same time.

[0033] The movement of the movable screw block 604 drives the left push rod 801 to move, which in turn drives the connecting block 802 to move. The connecting block 802 then presses against the inclined surface of the slide plate 803. The inclined surface of the slide plate 803 is pressed and moves laterally. The movement of the slide plate 803 drives the push plate 804 to move, which in turn pushes the plate and adjusts its position to close it, thus preventing the weld from becoming incomplete.

[0034] The movement of the right push rod 607 drives the rack 805 to move, which in turn drives the first gear 807 to rotate. The rotation of the first gear 807 drives the screw 808 to rotate, which in turn drives the rust-removing scraper 809, which is threaded to it, to move up and down. The movement of the rust-removing scraper 809 drives the abrasive strip to scrape the area of ​​the plate to be welded, removing rust. At the same time, the up and down movement of the rust-removing scraper 809 drives the connecting rod 811 to move, which in turn drives the sealing piston 814 to move. The movement of the sealing piston 814 compresses the air at its top, causing the air to enter the air collection hood 810 at the top of the rust-removing scraper 809 through the small No. 3 hole and a hose, and then blow it out. This achieves the effect of scraping away rust while blowing it away, preventing rust or other dust and powder from affecting the welding.

[0035] The movement of slide plate 803 drives the movement of slider seat 905, which in turn drives the movement of second elastic telescopic rod 906. During welding, the movement of second elastic telescopic rod 906 causes its inclined surface to press against block 904. This pressure causes the output end of second elastic telescopic rod 906 to retract, allowing it to continue moving to the right without affecting the movement of slide plate 803. Upon completion of welding, second elastic telescopic rod 906 is positioned to the right of block 904. At this point, second elastic telescopic rod 906 moves to the left, driving block 904 to move. Block 904 then drives the movement of limit pin 903. The movement releases the limit on the first elastic telescopic rod 901. Released from its limit and influenced by the weight of the plate, the output end of the first elastic telescopic rod 901 retracts, causing the unloading plate 703 to flip and slide out the welded plate. The second elastic telescopic rod 906 moves to the left, causing the inclined top rod 907 to move. The movement of the inclined top rod 907 causes its inclined surface to press against the fixing rod 908. The pressure on the inclined surface of the inclined top rod 907 causes it to move upwards. This movement of the inclined top rod 907 then moves the second elastic telescopic rod 906, causing its output end to disengage from the locking block 904. Simultaneously, the locking block 904 is subjected to the action of the sixth spring, causing it to reset.

[0036] The unloading plate 703 flips and presses the inclined surface of the inclined plate 911. The inclined surface of the inclined plate 911 moves under the pressure. The movement of the inclined plate 911 drives the locking pin 912 to move. The locking pin 912 moves into the fifth hole and presses the inclined surface at the bottom of the output end of the third elastic telescopic plate 913. The inclined surface of the third elastic telescopic plate 913 moves upward under the pressure. The movement of the third elastic telescopic plate 913 drives the top block 914 to move. The top block 914 moves and rises, so that when the plate slides down, it can be lifted up and slide down above the previous plate. At the same time, when the plate slides down, it will be above the roller 910. The roller 910 rolls to reduce friction and make the plate move more smoothly. When the roller 910 is under pressure, it will drive the buffer seat 909 to descend. Under the action of the seventh spring, it will dampen the shock and reduce the impact of the plate during movement.
