Detailed implementation manners

[0018] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0019] Embodiment: As Figures 1-4 shown, the present invention provides a technical solution, a welding device for a new energy vehicle battery tray, including a processing platform 1. Both ends of one side of the processing platform 1 are installed with second electric telescopic columns by screws. One end of the second electric telescopic column is installed with a limiting plate by screws, which can limit both ends of the tray raw material to be welded, ensuring the stability of the movement of the tray raw material to be welded. An installation frame 2 is welded on the side of the processing platform 1. Both ends of the top of the installation frame 2 are installed with electric push rods 3 by screws. The bottoms of the two electric push rods 3 are connected by a cross electric slide rail 4. An automatic welding gun 5 is arranged at the bottom of the cross electric slide rail 4. A conveyor belt 43 is placed at one end of the top of the processing platform 1; As Figure 2 , Figure 5 -Figure 11 and Figure 18 As shown in Figure 18 , one end of the cross-shaped electric slide rail 4 is installed with a rack 6 through screws. A driving rod 7 is slidably connected inside the rack 6. A pushing column 8 is welded to the end of the driving rod 7. An installation plate 9 is installed on the top surface of the pushing column 8 through screws. The top surface of the installation 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 inside the T-shaped groove opened in the rack 6, which avoids the problem of the driving rod 7 falling off and facilitates driving the driving rod 7 to move, thereby facilitating the movement of the installation plate 9 and thus facilitating the unloading of the welded tray. One end of the top of the installation plate 9 is connected to a rotating plate 10 through a hinge. Limit plates are welded to both ends of the rotating plate 10. Limit grooves are opened on the top surface of the processing platform 1 corresponding to the positions of the limit plates, which can make the rotating plate 10 placed horizontally, thereby facilitating the placement of the plate. Two ends of one side of the top surface of the processing platform 1 are both installed with limit rods 22 through screws; One end of the processing platform 1 is rotatably connected to a straight gear connection mechanism 11. The straight gear connection mechanism 11 includes three straight gears. The ends of the three straight gears are all movably embedded and installed at one end of the processing platform 1. Two adjacent straight gears are meshed and connected. The rack 6 is meshed with one of the straight gears. One end of one of the straight gears in the straight gear connection mechanism 11 is installed with a ratchet 12 through screws. One end of one of the straight gears in the straight gear connection mechanism 11 is provided with a first belt connection mechanism 13. A spring steel 14 is welded inside one of the first belt pulleys in the first belt connection mechanism 13. The ratchet 12 is inside the first belt pulley in the first belt connection mechanism 13 where the spring steel 14 is installed. The ratchet 12 can be in contact with the spring steel 14. A plurality of rollers 16 are evenly rotatably connected to the top surface of the processing platform 1. The ends of several rollers 16 are fixedly connected with rotating shafts. The rotating shafts between two adjacent rotating shafts are connected by a second belt connection mechanism 15. One of the second belt pulleys in the second belt connection mechanism 15 is fixedly connected with one of the first belt pulleys in the first belt connection mechanism 13; A driving gear 17 is embedded and installed at one end of the side of the processing platform 1. The driving gear 17 can be meshed with the rack 6 to facilitate driving the driving gear 17 to rotate. One end of the driving gear 17 is fixedly connected with a third belt connection mechanism 18. A bidirectional screw 19 is fixedly sleeved inside one of the third belt pulleys in the third belt connection mechanism 18. Installation rods 42 are arranged at both ends of the outer side of the bidirectional screw 19 and on the top surface of the processing platform 1. The processing platform 1 is provided with limit grooves corresponding to the installation rods 42 at both ends of the outer side of the bidirectional screw 19. The installation rods 42 are slidably connected inside the limit grooves. The outer side of the installation rods 42 is in contact with the inner side of the limit grooves, ensuring the stability of the movement of the installation rods 42. The ends of the installation rods 42 are installed with first electric telescopic columns 20 through screws. One end of the first electric telescopic column 20 is installed with a clamping plate 21 through screws; After the raw materials are placed on the top of the rotating plate 10, the position of the automatic welding gun 5 is adjusted by the cross electric slide rail 4. Subsequently, the tray is welded by the automatic welding gun 5, and welding at different positions is achieved. After the tray welding is completed, the operator activates the first electric telescopic column 20 so that the clamping plate 21 does not contact the tray. Then, the operator activates the electric push rod 3 to drive 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 rack 6 to move, the movement of the rack 6 drives the driving rod 7 to move, the movement of the driving rod 7 drives the push column 8 to move, thereby driving the mounting plate 9 and the rotating plate 10 to move. Since the mounting plate 9 and the rotating plate 10 are rotationally connected, as the mounting plate 9 and the rotating plate 10 move, the rotating plate 10 will also rotate accordingly. At this time, the limiting rod 22 limits the end of the tray to prevent the problem of tray tilting. When the tray moves beyond the limiting rod 22, the tray will also tilt and slide at this time, and the tray will slide onto the conveyor belt 43 to achieve the unloading of the welded tray. When the cross electric slide rail 4 moves upward, at this time, the rack 6 is meshed and connected with the driving gear 17. At this time, through the connection of the driving gear 17 and the third belt connection mechanism 18, the bidirectional screw 19 will be driven to rotate. The rotation of the bidirectional screw 19 drives 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. And during the upward movement of the cross electric slide rail 4, at this time, the arc surface of the ratchet 12 contacts the arc surface of the spring steel 14, and thus the roller 16 will not be driven to rotate. At this time, the raw materials on the top of the roller 16 will not be displaced. After the tray unloading is completed, the electric push rod 3 is activated again to make the cross electric slide rail 4 and the automatic welding gun 5 move downward. At this time, the mounting plate 9 and the rotating plate 10 move downward due to gravity. When the end of the rotating plate 10 moves into the bearing groove, the rotating plate 10 rotates, so that the top surface of the rotating plate 10 is at the same horizontal plane as the top surface of the processing platform 1. And when the rack 6 moves, the rack 6 is meshed and connected with the straight gear connection mechanism 11, thereby driving the straight gear connection mechanism 11 to rotate. At this time, the tip of the ratchet 12 contacts the tip of the spring steel 14, and at this time, the first belt connection mechanism 13 can be driven to rotate. By driving the second belt connection mechanism 15 to rotate, several rollers 16 can be driven to rotate. The rotation of the rollers 16 makes the raw materials on the top of the rollers 16 move, thereby realizing the feeding of the raw materials on the top of the rollers 16, moving the raw materials to the top of the rotating plate 10. And as the rack 6 moves, the rack 6 is meshed and connected with the driving gear 17, thereby driving the bidirectional screw 19 to rotate again, making the mounting rod 42 reset. Then, the first electric telescopic column 20 is activated to drive the clamping plate 21 to move and clamp the raw materials, facilitating the subsequent welding of multiple raw materials into a tray.

[0020] As Figure 12 - Figure 17As shown in the figure, drive motors 23 are installed at both ends of the bottom of the cross electric slide rail 4 near the two ends of the automatic welding torch 5 through screws. The output shaft of the drive motor 23 is fixedly connected with a spring telescopic rod 24. The bottom of the spring telescopic rod 24 is installed with a polishing plate 25 through screws. The output shaft of the drive motor 23 is fixedly connected with a bevel gear connection mechanism 26. One end of the bevel gear connection mechanism 26 is fixedly installed with a driving shaft 27. A fan blade 28 is fixedly sleeved on the outer side of one end of the driving shaft 27. The driving shaft 27 is rotatably connected to the bottom of the cross electric slide rail 4. One end of the processing platform 1 is installed with a fixed box 29 through screws. One end of the top of the fixed box 29 is installed with a filter screen to prevent dust from entering the inside of the return pipe 33. A storage box 30 is slidably connected inside the fixed box 29. The top of the fixed box 29 is penetrated and connected with an air inlet pipe 31. One end of the air inlet pipe 31 is fixedly connected with an absorption pipe 32. The fan blade 28 is located inside the absorption pipe 32, which is convenient for sucking dust into the absorption pipe 32 and ensuring the stability of the rotation of the driving shaft 27. One end of the bottom of the absorption pipe 32 is arc-shaped, and suction slots are evenly arranged at one end of the bottom of the absorption pipe 32, which is convenient for collecting dust. The bottom of the absorption pipe 32 is located outside the polishing plate 25, which is convenient for adsorbing the dust generated during the polishing of the polishing plate 25. One side of the fixed box 29 is penetrated and connected with a return pipe 33 through threads. One end of the return pipe 33 is installed with a second spring telescopic column 40 through screws. One end of the second spring telescopic column 40 is installed with a sealing ball 41 through screws, which is convenient for closing the end of the air blowing pipe 39 and preventing the problem of air reflux.

[0021] A placement box 34 is placed at one end of the bottom of the processing platform 1. A plurality of first spring telescopic columns 36 are evenly installed on the inner bottom surface of the placement box 34 through screws. The tops of the first spring telescopic columns 36 are connected by a closing plate 37. One end of the placement box 34 is penetrated and connected with a connecting pipe 38. One end of the top of the connecting pipe 38 is fixedly installed with an air blowing pipe 39. One end of the return pipe 33 is fixedly connected with one end of the air blowing pipe 39, which is convenient for cooling during the welding process. The bottom of the rack bar 6 is installed with an L-shaped rod 35 through screws. One end of the L-shaped rod 35 is located on the top of the placement box 34. A rubber frame is adhered to the outside of the closing plate 37. A closing frame is installed on the top of the placement box 34 through screws, which is convenient for limiting the closing plate 37 and enhancing the sealing performance between the closing plate 37 and the placement box 34. At the same time, it is convenient to push the closing plate 37 to move.

[0022] During the processing of the battery tray, as the rack bar 6 moves, it drives the L-shaped rod 35 to move. Through the movement of the L-shaped rod 35, the closing plate 37 is pushed to move, so that the first spring telescopic column 36 is compressed. By compressing the gas inside the placement box 34 through the closing plate 37, the gas inside the placement box 34 enters the inside of the air blowing pipe 39 through the connecting pipe 38 and is blown out through the air blowing pipe 39 to blow the top of the rotating plate 10, ensuring the cleanliness of the surface of the rotating plate 10 and thus ensuring the stability during the tray welding process; During the grinding process, the drive motor 23 is turned on. By using the spring telescopic rod 24, the polishing plate 25 can be brought into contact with the surface of the tray, so that the connection position of the raw materials can be polished before and after welding. On the one hand, it can ensure the flatness of the connection position of the raw materials and the cleanliness of the surface of the raw materials before welding, thus facilitating the welding of the raw materials and improving the welding effect. On the other hand, after welding, the welding points can be polished, improving the automation degree of the welding device and the welding efficiency. Through the connection of the bevel gear connection mechanism 26, the drive shaft 27 and the fan blade 28 can be driven to rotate, so that the dust generated by polishing enters the inside of the air inlet pipe 31 through the suction pipe 32, and the dust enters the inside of the storage box 30 for dust collection, avoiding the problem that the dust splashes everywhere during the polishing process and affecting the surrounding environment. Moreover, the air entering the inside of the storage box 30 is blown out through the return pipe 33 and then enters the inside of the air blowing pipe 39 to realize the cooling of the tray during the welding process, so that the welding position can be quickly cooled, and thus it is convenient for personnel to polish the welding position.
