[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figure 1-6 As shown, the automatic positioning and feeding device for airbag welding disclosed in this utility model includes a material transfer component 3 for horizontal material conveying, and a lifting component 2 set at the material conveying end inlet of the material transfer component 3. A lifting plate conveying component 1 is provided at the end of the lifting component 2 away from the material transfer component 3, and a lifting sinking component 4 is provided at the end of the material transfer component 3 away from the lifting component 2. The lifting plate conveying assembly 1 includes a first conveying screw 102 that is horizontally arranged toward the lifting assembly 2 and can rotate around its own axis. The first conveying screw 102 is threaded with a conveying driven beam 103 that can be driven to move. The conveying driven beam 103 in this technical solution adopts a horizontally placed U-shaped structure component, both ends of which are connected to the conveying rails 104. Two rows of conveying rails 104 are horizontally parallel arranged at the end of the conveying driven beam 103 toward the lifting assembly 2. Several lifting cylinders 1041 are uniformly fitted on the conveying rails 104. The output end of the lifting cylinder 1041 is set upward and a limiting tooth block 1042 is connected to the output end. The limiting tooth block 1042 adopts a horizontally arranged L-shaped component. When the height of the limiting tooth block 1042 decreases, its L-shaped end will lock the side of the material limiting frame 504, thereby driving the material lifting assembly 5 to move.

[0017] The lifting assembly 2 includes a height-adjustable lifting plate 202, which is a rectangular sheet component. Lifting rails 203 parallel to the material conveying rail 104 are provided on both sides of the top of the lifting plate 202. Material lifting assemblies 5 can be placed on the lifting rails 203. When the material lifting assemblies 5 are placed on the lifting rails 203, they can be held in place by the lifting cylinder 1041, which is adjusted and lowered by the lifting cylinder 1041, and transported by the displacement of the material conveying rail 104.

[0018] Specifically, the material transfer component 3 includes several vertically arranged support seats 301, and a horizontally arranged conveying track 302 for conveying materials is located on the support seats 301. The conveying track 302 and the lifting track 203 are on the same straight line. Several sets of positioning components are evenly arranged on the material transfer component 3. The positioning components include positioning cylinders 303 that are directly fixed. A positioning block 304 is connected to the output end of the positioning cylinder 303. In this embodiment, the distance between each support seat 301 is the same as the distance between each material lifting component 5.

[0019] Specifically, the material lifting assembly 5 includes a material lifting plate 501. The bottom end of the material lifting plate 501 is provided with several sets of fitting sliders 502 that can be fitted with the lifting track 203 and the conveying track 302. The bottom end of the material lifting assembly 5 is also provided with a positioning protrusion 503 that cooperates with the positioning block 304. When the positioning cylinder 303 drives the positioning block 304 to push out, it cooperates with the positioning protrusion 503, so that the material lifting assembly 5 completes the positioning. In this embodiment, the upper surface of the positioning block 304 is provided with a recessed groove, which matches the positioning protrusion 503.

[0020] Specifically, a material limiting frame 504 is fixedly installed at the outer edge of the upper surface of the material lifting plate 501. Several workpieces 505 to be processed are arranged inside the material limiting frame 504. In this embodiment, the workpieces 505 to be processed are welded during the conveying and transfer process by processing components added to the device. Since the processing components added to the device are not part of the technology exposed in this technical solution, they are not disclosed here.

[0021] Specifically, the material transfer component 3 is provided with two layers of support bases 301 and conveying rails 302 at different heights. Each conveying rail 302 is provided with a positioning component on its outer side. In this embodiment, the positioning component facilitates the precise positioning of each material lifting plate 501 during transportation.

[0022] Specifically, a first servo motor 101 is fixedly mounted on one side of the first conveying screw 102 via a bracket. The first servo motor 101 is driven by the first conveying screw 102 via a transmission chain. A second conveying screw 106, which can be driven around its axis, is also arranged parallel to the first conveying screw 102. A second servo motor 105, which is driven by the second conveying screw 106 via a transmission chain, is also arranged below the second conveying screw 106. A return material driven beam 107, which can be driven to move, is threaded on the second conveying screw 106. Two rows of return material conveying rails 108 are arranged horizontally and parallel to the end of the return material driven beam 107 facing the lifting component 2. Lifting cylinders 1041 and limiting teeth 1042 are also evenly arranged on the return material conveying rails 108. In this embodiment, the rising component and the falling component adopt the same technical route, which makes it easier for on-site personnel to operate.

[0023] Specifically, the lifting assembly 2 includes a vertically arranged lifting telescopic rod 201. The output end of the lifting telescopic rod 201 is connected to the bottom end of the lifting support plate 202 and its height is adjusted. The bottom surface of the lifting support plate 202 is also provided with several stabilizing rods 204. The bottom end of the stabilizing rod 204 passes through the rod to ensure the stability of the lifting support plate 202. The lifting and sinking assembly 4 includes a sinking telescopic rod 401 and a sinking lifting plate 402. The structure of the lifting and sinking assembly 4 is the same as that of the lifting and raising assembly 2. The sinking telescopic rod 401 is the same as the lifting telescopic rod 201. The second stabilizing rod 404 is the same as the stabilizing rod 204.

[0024] The working principle and usage process of this utility model: In the process of using the feeding device in this utility model, the workpiece 505 to be processed is placed inside the material limiting frame 504, and the material lifting plate 501 is placed on the lifting track 203 through the interlocking slider 502. During the operation of the lifting telescopic rod 201, the height of the lifting plate 202 is raised by pushing out its own telescopic rod, so that the lifting track 203 and the upper conveying track 302 are kept on the same straight line. Then, the first servo motor 101 is powered on and starts running, driving the first conveying screw 102 to run. During the operation of the first conveying screw 102, the material conveying driven beam 103 is displaced, and the material conveying rail 104 is pushed out horizontally at the same time. During the horizontal displacement of the material conveying rail 104, the lifting cylinder 1041 and the limiting tooth block 1042 are driven to move horizontally. During this process, the lifting cylinder 1041 retracts, causing the height of the limiting tooth block 1042 to drop. At this time, the end of the limiting tooth block 1042 will abut against the outer extension of the material limiting frame 504. During the horizontal displacement of the material conveying rail 104, the limiting tooth block 1042 drives the material lifting assembly 5 to slide and move from the lifting rail 203. After the conveying driven beam 103 drives the material lifting assembly 5 forward one body position, the lifting cylinder 1041 extends, causing the limiting tooth block 1042 to separate from the material lifting assembly 5. Then, the first servo motor 101 rotates in the reverse direction, driving the first conveying screw 102 to rotate in the reverse direction as well, causing the conveying driven beam 103 to reset. Then, the lifting cylinder 1041 retracts and repeats the above process, using the limiting tooth block 1042 to hold the next material lifting assembly 5, thus conveying the material lifting assembly 5 one body position at a time. At this time, the material lifting component 5 passes through the material transfer component 3 and is processed by other processing workpieces set on the material transfer component 3. The processed material lifting component 5 is then transported to the lifting and sinking component 4. The processed workpiece 505 is gripped onto the finished product conveyor line by the gripping robot arm set above the lifting and sinking assembly 4. The remaining empty material lifting assembly 5 is driven to sink on the lifting and sinking assembly 4 by the sinking telescopic rod 401. The lifting cylinder 1041 and the limiting tooth block 1042 on the return conveying rail 108 set in the lower layer of the material transfer component 3 are hooked. The second servo motor 105 drives the second conveying screw 106 to run. The second conveying screw 106 drives the return driven beam 107 and the return conveying rail 108 to run back and forth, so that the empty material lifting component 5 is transported to the lifting component 2 through the lower conveying rail 302. The lifting telescopic rod 201 drives its telescopic end to retract, so that the lifting lifting plate 202 is directly below the empty material lifting component 5. The locking slider 502 at the bottom of the material lifting component 5 slides on the conveying rail 302 to the lifting rail 203. Then, the telescopic rod 201 is raised and extended to lift the empty material lifting assembly 5 upward. Then, the workpiece 505 to be processed is placed inside the material limiting frame 504 through the external feeding equipment. The above process is repeated to transport the material lifting assembly 5 and process the workpiece 505.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to further limit the present utility model. All equivalent changes made based on the description and drawings of the present utility model are within the protection scope of the present utility model.
