Description

Technical Field

[0001] This utility model relates to a novel laser welding equipment for welding steel drums, belonging to the technical field of automatic steel drum production line equipment. Background Technology

[0002] With the rapid development of the steel drum manufacturing industry, energy conservation, emission reduction, and cost reduction will be the mainstream development direction for automated steel drum production lines, gradually replacing the current high-power production lines. In previous automated steel drum production lines, steel plate blanks, after being cut, edge-grinding, rolled, and welded, would arrive at the intermediate equipment. For steel drums made of galvanized sheet, edge grinding was required before rolling and welding, while laser welding eliminates the need for pre-grinding. Traditional resistance welding machines require high current, necessitating numerous structural copper components, and ensuring conductivity and insulation results in high material, processing, and assembly costs. The new laser welding machine eliminates the need for steel plate edge grinding, has a simpler structure, and offers better cost-effectiveness. However, existing steel drum laser welding equipment is limited to a single unit, which cannot meet production demands based on the production cycle. Summary of the Invention

This laser welding equipment adopts a parallel structure, can be flexibly combined according to customer needs, and has the advantages of being fully automatic and having a high utilization rate.

[0004] To solve the above problems, the specific technical solution of this utility model is as follows: A novel laser welding equipment for welding steel drums includes a transfer manipulator and a laser welding machine; wherein several laser welding machines are arranged in parallel, and each laser welding machine has a transmission mechanism at its bottom, with one end of the transmission mechanism extending out of the laser welding machine to form a waiting area; a transfer manipulator is provided above the extended ends of the several transmission mechanisms; the transfer manipulator includes a transfer frame, a guide rail slider, a transfer motor, and a clamping mechanism; the transfer frame spans all the transmission mechanisms, and a guide rail slider is provided at the top of the transfer frame, with the clamping mechanism connected to the guide rail slider; a transfer motor is provided at the end of the guide rail slider, and the transfer motor is connected to the guide rail slider through a transmission device; a stop mechanism is provided at the front end of the clamping mechanism, and after a steel drum located on one of the transmission mechanisms is stopped by the stop mechanism, the clamping mechanism grips the steel drum and transfers it to the transmission mechanism of another laser welding machine.

[0005] The laser welding machine includes a welding machine frame, a barrel-holding mechanism, a guide wheel structure, a clamping structure, a welding torch transmission structure, and a center positioning structure. The top of the welding machine frame has a long, narrow opening for the movement of the welding torch. A welding torch transmission structure is located at the side end of the opening, with its running direction parallel to the axis of the steel barrel. The welding torch is connected to the welding torch transmission structure. Inside the welding machine frame, above the transmission mechanism, is a barrel-holding mechanism and a guide wheel structure, evenly distributed around the outer circumference of the steel barrel. Several clamping structures are located at the long, narrow opening of the welding machine frame, with the working ends of the clamping structures contacting both sides of the weld seam on the steel barrel.

[0006] The welding machine frame is also provided with a central positioning structure at the long opening. The central positioning structure is provided with a central positioning plate that can be extended vertically. After being lowered, the central positioning plate is inserted into the unwelded weld of the steel barrel.

[0007] The central positioning structure is equipped with cylinder II. One end of cylinder II is hinged to the welding machine frame, and the piston rod of the other end is connected to the external hinge point of the parallelogram connecting rod frame. One short side of the connecting rod frame is fixedly connected to the welding machine frame, and the other short side of the connecting rod frame is fixedly connected to the vertical central positioning plate.

[0008] The main shaft is located directly below the long opening of the welding machine frame. One end of the main shaft is fixedly connected to the welding machine frame, and the other end is connected and positioned to the main shaft fixing structure.

One end of the rocker arm is rotatably connected to the welding machine frame through a bearing seat, and the other end is snapped to the end of the main shaft.

[0010] The welding machine frame is provided with a front stop structure and a rear alignment structure at both ends. The front stop structure limits the front end of the steel barrel, and the rear alignment structure limits the rear end of the steel barrel.

[0011] The novel laser welding equipment of this application adopts the above structure and has the following advantages:

[0021] like Figures 1 to 4 As shown, a novel laser welding equipment for welding steel drums includes a transfer manipulator 2 and a laser welding machine 3. Several laser welding machines 3 are arranged in parallel, and each laser welding machine 3 has a transmission mechanism 33 at its bottom. One end of the transmission mechanism 33 extends out of the laser welding machine 3 to form a waiting area, and a rolling machine 1 is located at the front end of the waiting area. The transfer manipulator 2 is arranged above the extended ends of the several transmission mechanisms 33. The transfer manipulator 2 includes a transfer frame 25, a guide rail slider 24, a transfer motor 23, and a clamping mechanism 22. The transfer frame 25 spans all the transmission mechanisms 33. A guide rail slider 24 is located at the top of the transfer frame 25, and a clamping mechanism 22 is connected to the guide rail slider 24. A transfer motor 23 is located at the end of the guide rail slider 24, and the transfer motor 23 is connected to the guide rail slider 24 via a transmission device. A stop mechanism 21 is located at the front end of the clamping mechanism 22. After a steel drum located on one of the transmission mechanisms 33 is stopped by the stop mechanism 21, the clamping mechanism 22 grips the steel drum and transfers it to the transmission mechanism 33 of another laser welding machine 3. The transfer robot 2 can feed the steel drum rolled in the previous rolling machine 1 into different laser welding machines in a rhythmic manner, thereby improving work efficiency.

[0022] like Figures 3 to 4 As shown, the laser welding machine 3 includes a welding machine frame 31, a barrel-holding mechanism 34, a guide wheel structure 35, a clamping structure 36, a welding torch transmission structure 37, and a center positioning structure 311. The top of the welding machine frame 31 has a long opening for the movement of the welding torch. A welding torch transmission structure 37 is located at the side end of the opening, with its running direction parallel to the axis of the steel barrel. The welding torch is connected to the welding torch transmission structure 37. Inside the welding machine frame 31, above the transmission mechanism 33, is a barrel-holding mechanism 34 and a guide wheel structure 35, which are evenly distributed around the outer circumference of the steel barrel. Several clamping structures 36 are located at the long opening of the welding machine frame 31, with the working ends of the clamping structures 36 contacting both sides of the weld seam of the steel barrel.

[0023] like Figure 6 As shown, the welding machine frame 31 also has a central positioning structure 311 at its long opening. The central positioning structure 311 contains a vertically retractable central positioning plate 3116. The lowered central positioning plate 3116 is inserted into the unwelded weld seam of the steel drum. For example... Figure 5 As shown, the central positioning structure 311 contains a cylinder II 3112. The cylinder II 3112 is inclined and one end is hinged to the welding machine frame 31. The piston rod at the other end is connected to the external hinge point of a parallelogram-shaped connecting rod frame 3115. One short side of the connecting rod frame 3115 is fixedly connected to the welding machine frame 31, and the other short side of the connecting rod frame 3115 is fixedly connected to the vertical central positioning plate 3116. The parallelogram structure ensures that the central positioning plate 3116 remains vertical and performs the lifting and lowering function.

[0024] like Figure 3 As shown in the partial sectional view on the right, a main shaft 40 is located directly below the elongated opening of the welding machine frame 31. One end of the main shaft 40 is fixedly connected to the welding machine frame 31, and the other end is connected and positioned to the main shaft fixing structure 38.

[0025] like Figure 5 As shown, the main shaft fixing structure 38 includes a cylinder I382 and a rocker arm 384. One end of the cylinder I382 is hinged to the welding machine frame 31, and the piston rod at the other end is hinged to the rocker arm 384. One end of the rocker arm 384 is rotatably connected to the welding machine frame 31 through a bearing seat, and the other end is snapped to the end of the main shaft 40.

[0026] The welding machine frame 31 is provided with a front stop structure 310 and a rear alignment structure 39 at both ends. The front stop structure 310 limits the front end of the steel barrel, and the rear alignment structure 39 limits the rear end of the steel barrel.

[0027] The operation flow of the novel laser welding equipment for steel drum welding in this application is as follows: After the steel plate billet is cut and rolled into a drum sleeve by the rolling machine 1, the drum sleeve is transferred to the waiting area of ​​the transmission mechanism 33 of the laser welding machine. It is then transferred into the laser welding machine via the transmission mechanism 33. The cylinder II 3112 of the center positioning structure 311 is activated before the drum sleeve enters, causing the center positioning plate 3116 to insert into the welding seam. Then, the front stop structure 310 is activated, raising the baffle plate to perform front positioning of the drum sleeve. Next, the rear alignment structure 39 is activated to position the rear end face of the drum sleeve. Finally, the drum clamping mechanism 34 is activated, clamping the drum sleeve tightly, with the edge of the drum sleeve abutting against the positioning plate 311 of the center positioning structure 311. On 116, the barrel-holding mechanism 34 on one side is released, the positioning plate 3116 of the middle positioning structure 311 is reset, the clamping structure 36 on the released barrel-holding side is lifted, and then the barrel-holding mechanism 34 on this side is tightened again. The welding torch transmission structure 37 drives the welding torch to weld the positioned barrel sleeve gap. After welding, the alignment structure 39, the front stop structure 310, the clamping structure 36, and the main shaft fixing structure 38 are reset. The transmission structure 33 transmits this welded steel barrel and transmits the next barrel sleeve to the welding station. When this welding machine has barrel sleeves to weld, the barrel sleeves on the waiting area of ​​the transmission mechanism 33 are transferred by the transfer robot 2 to the waiting area of ​​the unworking welding machine transmission mechanism 33 next to it.

[0028] The specific operation process of the transfer robot 2 is as follows: The gripper of the transfer robot 2 stops in advance above the welding machine transfer mechanism 33. The barrel sleeve is fed in, the front stop mechanism 21 lowers the baffle to prevent the barrel sleeve from being over-transferred, the clamping structure 22 is activated, the clamping plate clamps the barrel sleeve, and then the whole thing is raised. The transfer motor 23 drives the clamping mechanism 22 to move along the guide rail slider 24 to the side above the welding machine transfer mechanism 33. The clamping mechanism 22 lowers the barrel sleeve, the front stop mechanism 21 and the clamping structure 22 reset to open the barrel sleeve, the transfer power structure 23 drives the clamping mechanism 22 to reset along the guide rail slider 24, and the clamping structure 22 picks up a new barrel sleeve and moves it to the empty welding machine transfer mechanism 33, and repeats the motion.
