[0014] Preferably, one end of the L-shaped rod is located at the top of the placement box, a rubber frame is glued to the outside of the sealing plate, and a sealing frame is installed on the top of the placement box by screws.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0016] The use of electric push rods, cross-shaped electric slide rails, and automatic welding guns facilitates automatic welding of raw materials and allows for easy adjustment of the welding gun's position, enabling welding at different locations. This achieves automated welding during pallet processing, improving welding efficiency. After welding, the automatic welding gun moves upwards, cooperating with the mounting plate, rotating plate, and drive rod to automatically unload the pallet. When the automatic welding gun moves downwards, it works with a spur gear connecting mechanism, multiple belt connecting mechanisms, and rollers to load unprocessed raw materials. This achieves automated loading and unloading during pallet production, eliminating the need for manual operation and reducing labor intensity. The seamless loading and unloading process during pallet welding further... It can continuously weld pallets, thereby improving the efficiency of pallet welding. During the welding process, the use of the first electric telescopic column and clamping plate can weld the raw materials, ensuring the stability of the raw materials during the welding process, thus ensuring the efficiency of raw material welding. Moreover, during the downward movement of the automatic welding gun, the use of the placement box, L-shaped rod, sealing plate and blowing pipe can blow on the surface of the rotating plate after it is placed and stabilized, ensuring the cleanliness of the rotating plate surface, thus ensuring the stability of the raw materials placed on the rotating plate, avoiding the problem of raw materials tilting due to impurities on the rotating plate surface, thus avoiding the problem of scrapped welded pallets, reducing the scrap rate of pallets, and thus reducing the cost of pallet welding.

[0017] During the welding process, the use of a drive motor, spring telescopic rod, and polishing plate allows for polishing of parts at both ends of the automatic welding gun. This ensures the flatness of the material connection point and the cleanliness of the material surface before welding, facilitating welding and guaranteeing the effectiveness of tray welding. Furthermore, post-weld polishing enhances the automation of the welding device, eliminating the need for additional polishing steps and improving tray production efficiency. The use of a bevel gear connection mechanism, fan blades, a fixing box, a storage box, and an absorption tube collects dust during polishing, preventing dust splattering and environmental impact. The return air blows directly onto the battery tray surface, cooling the tray during welding and rapidly cooling the welding area, thus improving cooling efficiency. Attached Figure Description

[0039] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] Example: Figure 1-4As shown, the present invention provides a technical solution: a welding device for a new energy vehicle battery tray, including a processing platform 1. Two electric telescopic columns are installed on both ends of one side of the processing platform 1 by screws. A limit plate is installed on one end of the second electric telescopic column by screws, which can limit the two ends of the tray material to be welded, ensuring the stability of the movement of the tray material to be welded. A mounting frame 2 is welded on the side of the processing platform 1. Electric push rods 3 are installed on both ends of the top of the mounting frame 2 by screws. The bottom of the two electric push rods 3 are connected by a cross electric slide rail 4. An automatic welding gun 5 is set at the bottom of the cross electric slide rail 4. A conveyor belt 43 is placed on one end of the top of the processing platform 1.

[0041] like Figure 2 , Figure 5 - Figure 11 and Figure 18 As shown, a toothed rod 6 is installed at one end of the cross-shaped electric slide rail 4 by screws. A driving rod 7 is slidably connected inside the toothed rod 6. A push column 8 is welded to the end of the driving rod 7. A mounting plate 9 is installed on the top surface of the push column 8 by screws. The top surface of the mounting plate 9 is inclined. The cross-section of one end of the driving rod 7 is T-shaped. The T-shaped end of the driving rod 7 is slidably connected to the T-shaped groove opened in the toothed rod 6 to prevent the driving rod 7 from falling off and to facilitate the movement of the driving rod 7, which in turn facilitates the movement of the mounting plate 9, thus facilitating the unloading of the welded pallet. A rotating plate 10 is connected to the top end of the mounting plate 9 by a hinge. Both ends of the rotating plate 10 are welded with limiting plates. A limiting groove is opened on the top surface of the processing platform 1 at the position corresponding to the limiting plate, which allows the rotating plate 10 to be placed horizontally, thus facilitating the placement of the material. Limiting rods 22 are installed on both ends of one side of the top surface of the processing platform 1 by screws.

[0042] A spur gear connecting mechanism 11 is rotatably connected to one end of the processing platform 1. The spur gear connecting mechanism 11 includes three spur gears, the ends of which are movably embedded in one end of the processing platform 1. Two adjacent spur gears mesh with each other. A rack 6 meshes with one of the spur gears. A ratchet 12 is installed at one end of one of the spur gears in the spur gear connecting mechanism 11 by a screw. A first belt connecting mechanism 13 is provided at one end of one of the spur gears in the spur gear connecting mechanism 11. A spring steel 14 is welded inside a first pulley in the first belt connecting mechanism 13. The ratchet 12 is located inside the first pulley with the spring steel 14 installed in the first belt connecting mechanism 13. The ratchet 12 can contact the spring steel 14. Multiple rollers 16 are rotatably connected to the top surface of the processing platform 1. Rotating shafts are fixedly connected to the ends of several rollers 16. Two adjacent rotating shafts are connected through a second belt connecting mechanism 15. A second pulley in the second belt connecting mechanism 15 is fixedly connected to a first pulley in the first belt connecting mechanism 13.

[0043] A drive gear 17 is embedded in one side of the processing platform 1. The drive gear 17 can mesh with the rack 6 to facilitate the rotation of the drive gear 17. A third belt connection mechanism 18 is fixedly connected to one end of the drive gear 17. A bidirectional screw 19 is fixedly sleeved inside one of the third pulleys in the third belt connection mechanism 18. Mounting rods 42 are provided at both ends of the outer side of the bidirectional screw 19 and on the top surface of the processing platform 1. Limiting grooves are opened on the processing platform 1 corresponding to the mounting rods 42 at both ends of the outer side of the bidirectional screw 19. The mounting rods 42 are slidably connected inside the limiting grooves. The outer side of the mounting rods 42 is in contact with the inner side of the limiting grooves to ensure the stability of the movement of the mounting rods 42. A first electric telescopic column 20 is installed at the end of the mounting rod 42 by screws. A clamping plate 21 is installed at one end of the first electric telescopic column 20 by screws.

[0044] After the raw material is placed on top of the rotating plate 10, the position of the automatic welding gun 5 is adjusted by the cross electric slide rail 4. Then, the automatic welding gun 5 is used to weld the pallet and weld at different positions. After the pallet welding is completed, the operator opens the first electric telescopic column 20 so that the clamping plate 21 does not contact the pallet. Then, the operator opens the electric push rod 3, which drives the cross electric slide rail 4 and the automatic welding gun 5 to move. The movement of the cross electric slide rail 4 drives the toothed rod 6 to move. The movement of the toothed rod 6 drives the drive rod 7 to move. The movement of the drive rod 7 drives the push column 8 to move, which in turn drives the mounting plate 9 and the rotating plate 10 to move. Since the mounting plate 9 and the rotating plate 10 are rotatably connected, the rotating plate 10 will also rotate as the mounting plate 9 and the rotating plate 10 move. At this time, the limit rod 22 limits the end of the pallet to prevent the pallet from tilting. When the pallet moves beyond the limit rod 22, the pallet will also tilt and slide, and the pallet will slide onto the conveyor belt 43 to achieve unloading of the welded pallet.

[0045] When the cross electric slide rail 4 moves upward, the rack 6 meshes with the drive gear 17. At this time, the connection between the drive gear 17 and the third belt connecting mechanism 18 will drive the bidirectional screw 19 to rotate. The rotation of the bidirectional screw 19 will drive the mounting rod 42 to move, so that the two mounting rods 42 move in opposite directions, opening one end of the top of the processing platform 1. During the upward movement of the cross electric slide rail 4, the arc surface of the ratchet 12 contacts the arc surface of the spring steel 14, thus preventing the roller 16 from rotating. At this time, the raw material at the top of the roller 16 will not be displaced.

[0046] After the pallet unloading is completed, the electric push rod 3 is activated again, causing the cross electric slide rail 4 and the automatic welding gun 5 to move downwards. At this time, the mounting plate 9 and the rotating plate 10 move downwards due to gravity. When the end of the rotating plate 10 moves into the bearing groove, the rotating plate 10 rotates, making the top surface of the rotating plate 10 and the top surface of the processing platform 1 the same horizontal plane. When the rack 6 moves, the rack 6 meshes with the spur gear connecting mechanism 11, thereby driving the spur gear connecting mechanism 11 to rotate. At this time, the tip of the ratchet 12 contacts the tip of the spring steel 14, which can drive the first leather... The rotating belt connecting mechanism 13 drives the second belt connecting mechanism 15 to rotate, which in turn drives several rollers 16 to rotate. The rotation of the rollers 16 causes the raw material at the top of the rollers 16 to move, thus realizing the feeding of the raw material at the top of the rollers 16. The raw material is moved to the top of the rotating plate 10. As the rack 6 moves, the rack 6 meshes with the driving gear 17, which in turn drives the bidirectional screw 19 to rotate again, causing the mounting rod 42 to reset. Then the first electric telescopic column 20 is activated, which drives the clamping plate 21 to move and clamp the raw material, making it easier to weld multiple raw materials into a pallet later.

[0047] like Figure 12 - Figure 17 As shown, drive motors 23 are mounted on both ends of the cross-shaped electric slide rail 4 near the automatic welding gun 5 with screws. A spring telescopic rod 24 is fixedly connected to the output shaft of the drive motor 23. A polishing plate 25 is mounted on the bottom of the spring telescopic rod 24 with screws. A bevel gear connecting mechanism 26 is fixedly connected to the output shaft of the drive motor 23. A drive shaft 27 is fixedly mounted on one end of the bevel gear connecting mechanism 26. A fan blade 28 is fixedly sleeved on the outer side of one end of the drive shaft 27. The drive shaft 27 is rotatably connected to the bottom of the cross-shaped electric slide rail 4. A fixed box 29 is mounted on one end of the processing platform 1 with screws. A filter screen is mounted on the top end of the fixed box 29 with screws to prevent dust from entering the return pipe 33. A storage box 30 is slidably connected inside the fixed box 29. An air inlet pipe 31 is connected through the top, and an absorption pipe 32 is fixedly connected to one end of the air inlet pipe 31. The fan blade 28 is located inside the absorption pipe 32, which facilitates the suction of dust into the absorption pipe 32 and ensures the stability of the rotation of the drive shaft 27. The bottom end of the absorption pipe 32 is arc-shaped, and suction grooves are evenly opened at the bottom end of the absorption pipe 32 to facilitate the collection of dust. The bottom of the absorption pipe 32 is located outside the polishing plate 25, which facilitates the adsorption of dust from the polishing of the polishing plate 25. A return pipe 33 is threadedly connected through one side of the fixed box 29. A second spring telescopic column 40 is installed at one end of the return pipe 33 by screws. A sealing ball 41 is installed at one end of the second spring telescopic column 40 by screws to seal the end of the blowing pipe 39 and prevent the problem of air backflow.

[0048] A placement box 34 is placed at one end of the bottom of the processing platform 1. Multiple first spring telescopic columns 36 are evenly installed on the bottom surface of the placement box 34 by screws. The top of the first spring telescopic columns 36 are connected by a sealing plate 37. A connecting pipe 38 is connected through one end of the placement box 34. A blower pipe 39 is fixedly installed at the top end of the connecting pipe 38. One end of the return pipe 33 is fixedly connected to one end of the blower pipe 39 to facilitate cooling during the welding process. An L-shaped rod 35 is installed at the bottom of the toothed rod 6 by screws. One end of the L-shaped rod 35 is at the top of the placement box 34. A rubber frame is glued to the outside of the sealing plate 37. A sealing frame is installed at the top of the placement box 34 by screws to limit the position of the sealing plate 37 and enhance the sealing between the sealing plate 37 and the placement box 34. It also facilitates the movement of the sealing plate 37.

[0049] During the battery tray processing, as the rack 6 moves, it drives the L-shaped rod 35 to move. The movement of the L-shaped rod 35 pushes the closing plate 37 to move, causing the first spring telescopic column 36 to compress. The compression of the gas inside the placement box 34 by the closing plate 37 causes the gas inside the placement box 34 to enter the air blowing pipe 39 through the connecting pipe 38 and then blown out through the air blowing pipe 39 to blow air onto the top of the rotating plate 10, ensuring the cleanliness of the surface of the rotating plate 10, thereby ensuring the stability of the tray welding process.

[0050] During the polishing process, the drive motor 23 is turned on. Through the use of the spring telescopic rod 24, the polishing plate 25 can contact the surface of the tray, thereby polishing the connection position of the raw materials before and after welding. On the one hand, this ensures the flatness of the connection position of the raw materials and the cleanliness of the raw material surface before welding, which facilitates the welding of the raw materials and improves the welding effect. On the other hand, it can polish the welding point after welding, which improves the automation level of the welding device and improves the welding efficiency. Through the connection of the bevel gear connecting mechanism 26, the drive shaft 27 and the fan blade 28 can be driven to rotate, so that the dust generated during polishing enters the air inlet pipe 31 through the absorption pipe 32 and enters the collection box 30 for dust collection. This avoids the problem of dust splashing during polishing and affecting the surrounding environment. The air entering the collection box 30 is blown out through the return pipe 33 and then into the blowing pipe 39 to cool the tray during welding, which allows the welding position to cool down quickly, making it easier for personnel to polish the welding position.
