Description

Technical Field

[0002] In the technical field of automatic welding, with the rapid development of industrial automation, higher requirements are put forward for the efficiency, precision and safety of welding equipment. Although existing automatic welding equipment can achieve basic welding functions, it generally has the following defects: 1. High degree of manual intervention: It relies on manual for feeding and assembling operations, with high labor intensity. And manual operations are affected by subjective factors, prone to assembly errors, and it is difficult to ensure product consistency. 2. Low production efficiency: Adopting a single-station sequential processing mode, processes such as feeding, welding, and discharging need to be carried out in sequence, with long idle time of the equipment, unable to realize multi-process synchronous operation, resulting in limited overall production efficiency. 3. Prominent safety hazards: Frequent manual participation in the production process increases the risk of operators contacting welding equipment and high-temperature workpieces. Especially during the alternation of multiple processes, the probability of misoperation is relatively high, presenting greater safety hazards. 4. Insufficient environmental governance: There are no effective measures for collecting and treating the dust and harmful gases generated during the welding process, which not only pollutes the working environment but may also harm the health of operators. 5. Unstable welding quality: The traditional positioning and clamping methods have insufficient precision and cannot flexibly adjust the angle and position of workpieces according to welding process requirements, resulting in large fluctuations in welding quality and difficult to improve the finished product rate.

[0013] A double-head positioning automatic assembly welding and conveying device proposed by the present invention has the following beneficial effects: 1. Through the coordinated action of the feeding mechanism with the conveyor belt, the support plate, and the limiting wheels, automatic feeding and positioning of raw materials are achieved. Workers only need to complete the initial feeding in the safe area, greatly reducing the labor intensity; the lifting design of the support plate can accurately control the height of the raw materials, and cooperate with the stop posts and support columns to achieve position limiting, ensuring that the manipulator can accurately pick up the raw materials, avoiding manual operation errors, and improving the assembly accuracy; the combined design of the goods shelf and the conveying rack expands the feeding path, can process multiple types of raw materials simultaneously, and provides hardware support for the automatic assembly of complex workpieces.

[0015] 3. The enclosure structure isolates the working area from the operation area, effectively preventing the harm caused by the splashing of welding slag and the operation of equipment to personnel, and improving the production safety; the flue gas collection component, through the combination of the smoke machine and the dust suction pipe, collects the soot and harmful gases generated during the welding process in real - time, purifies the working environment, meets the requirements of modern industrial environmental protection, and ensures the health of the operators.

[0031] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0032] Step 1: Place the welding raw materials to be assembled on the material rack 51 and the goods rack 513, start the conveyor belt 53, so that the conveyor belt 53 drives the support base 54 to move forward smoothly under the restriction of the limit wheels 55 and the channel steel 52. Start the first cylinder 58, so that the first cylinder 58 pushes the pallet 57 to move upward under the restriction of the telescopic column 56, so that the pallet 57 lifts the assembled welding raw materials placed on the material rack 51. Through the conveyor belt 53, the raw materials have been moved to one side of the stop post 510. Control the pallet 57 to move downward, so that the raw materials fall on the material rack 51, thereby moving the raw materials into the moving range of the manipulator 3. Place the assembled raw materials on the goods rack 513 on the conveying rack 514, so that the conveying rack 514 moves the raw materials to one side to move into the moving range of the manipulator 3; Step 2: During assembly welding, use the manipulator 3 and the fixture 4 to clamp and move the assembled raw materials on the material rack 51 and the conveying rack 514 to the mold rack 711, and place the raw materials on the pallet 716. Start the hydraulic cylinder 713 and the second cylinder 715. After the hydraulic cylinder 713 is started, it can control one end of the limit fixture 714 to move up and down, so that the other end of the limit fixture 714 rotates around one side of the mold rack 711, so that the limit fixture 714 presses and fixes the raw materials on the mold rack 711. Start the transverse moving frame 712 to drive the second cylinder 715 and the pallet 716 to move to one side to fix the raw materials through the pallet 716 and the mold rack 711. The second cylinder 715 pushes the pallet 716 to move upward, thereby increasing the fixing strength of the raw materials to ensure accurate assembly; Step 3: Start the first reduction motor 77 to drive the rotating column 74 and the connecting column 75 to rotate. The rotating column 74 can drive the welding table 79 to rotate in a circle, so that the welding table 79 on one side of the manipulator 3 is flipped to the side of the welding robot 73. During the rotation, the second reduction motor 717 controls the rotation of the turntable 78 to keep the welding table 79 and the mold rack 711 always horizontally arranged. The welding robot 73 welds the assembly raw materials on the pair of mold racks 711. By controlling the deflection angle of the welding table 79, the welding angle of the assembly raw materials is adjusted to facilitate the welding of the welding robot 73. When welding the assembly raw materials on one side of the mold rack 711, the manipulator 3 uses the fixture 4 to clamp the finished products welded on the other side of the mold rack 711, moves them to the finished product conveyor 6 for conveying, and feeds the unassembled raw materials, effectively improving the processing efficiency of the product, reducing manual operation, and improving the processing quality of the product; Step 4: Start the fume extractor 91. Under the suction of the fume extractor 91, the gas generated by the welding of the welding robot 73 flows upward and is sucked into the dust suction pipe 93 to collect and purify the fumes, ensuring the production environment during indoor processing and production of the device, avoiding pollution, and being conducive to wide promotion.
