Description

Technical Field

[0001] The invention relates to the technical field of sheet material unloading and conveying, in particular to a sheet material unloading and conveying device for a welding line. Background Art

[0002] In the automobile manufacturing process, sheet metal unloading and conveying devices play a vital role. They are not only responsible for conveying the cut sheets from the cutting equipment to the welding station, but also ensure the stability and accuracy of the sheets during the welding process. As automobile manufacturing develops towards automation and intelligence, sheet metal unloading and conveying devices have also achieved seamless docking with welding robots, automated fixtures and other equipment, greatly improving production efficiency and product quality.

[0003] For example, a straight vacuum suction cup for an automated loading and unloading production line with announcement number CN219362486U can flexibly adjust the distance between the inner and outer suction cup assemblies according to the suction cup position of the workpiece on the production line. At the same time, the ball seat and the hinged ball can adapt to the situation when the surface of the suction cup body of the production line is tilted, which has better applicability. After the suction cup body of the production line is adsorbed, it can automatically assist in cleaning the filter plate, reducing the maintenance frequency of the filter plate. However, during the unloading process of the sheet, particulate impurities in the air and debris generated during the processing of the sheet will adhere to the surface of the sheet, resulting in a decrease in the sealing of the suction cup when adsorbed with the sheet, causing the sheet to slip or tilt during movement, affecting the stability and accuracy of the production line, and the falling of the sheet during the unloading process may also pose a safety hazard to the operators on the production line, which may cause personal injury or other safety accidents.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The sheet is grabbed through the movement of the robot's arm and placed on the electromagnetic platform. The electromagnetic platform absorbs the sheet and moves it to the stacking area.

[0035] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on the above embodiment 1. In the process of unloading the existing sheet metal, particulate impurities in the air and debris generated during the processing of the sheet metal will adhere to the surface of the sheet metal, causing the suction cup to lose its sealing when adsorbing the sheet metal, causing the sheet metal to slide or tilt during the unloading process, affecting the stability and accuracy of the production line.

The bottom end of the ventilation pipe 1303 is fixedly connected to a bracket 1302, and the end of the bracket 1302 away from the ventilation pipe 1303 is fixedly connected to the first work station 6. The cleaning mechanism 13 also includes a disc 1304, and a plurality of discs 1304 are provided, and the discs 1304 are fixedly arranged one by one on the outer wall of the suction cup 1205 connecting rod below the first work station 6. The discs 1304 are all hollow structures, and the discs 1304 are connected to the air outlet end of the ventilation pipe 1303 through a hose. A plurality of nozzles 1305 are arranged at equal intervals on the side wall of the disc 1304, and the nozzles 1305 are connected to the discs 1304.

[0036] In this technical solution, Figure 2As shown, by using the arrangement of the ventilation pipe 1303, the disc 1304 and the nozzle 1305, the air is transported from the ventilation pipe 1303 to the disc 1304 through the air pump 1301, and then sprayed out by the nozzle 1305 to clean the surface of the sheet material, so that the suction cup 1205 can be more accurately positioned and fitted when contacting the sheet material, reducing the suction cup adjustment time caused by impurities on the surface, and the ventilation pipe 1303 is arranged on the first workbench 6, and the first workbench 6 is located between the first vertical frame 4 and the second workbench 7, and then when the first workbench 6 moves, it will drive the ventilation pipe 1303 and the nozzle 1305 to move synchronously, ensuring that the nozzle 1305 can always blow air to the surface of the sheet material, so that it can fully cover every corner of the surface of the sheet material and enhance the cleaning effect. At the same time, the disk 1304 is larger than the diameter of the suction cup 1205, and thus can prevent the suction cup 1205 from being damaged to a certain extent.

[0037] It uses Figure 1 and Figure 3-Figure 6 According to the technical solution shown, after the sheet metal is welded, it flows to the unloading conveyor belt, which conveys the sheet metal to the bottom of the suction cup 1205. At this time, the main frame 2 is moved, so that the main frame 2 drives the side panel 3, the first stand 4, the second stand 5, the first work station 6 and the second work station 7 to move synchronously, so that the suction cup 1205 moves, and the air pump 1301 is started. The air pump 1301 will convey the gas to the ventilation pipe 1303 through the hose, and then the gas in the ventilation pipe 1303 will enter the disc 1304 through the hose, and finally be ejected by the nozzle 1305. Since the nozzle 1305 is set at an angle, the air flow cleans the sheet metal.

[0038] Then, as the main frame 2 moves downward, the two ends of the anti-drop rod 1408 are aligned with the side walls of the sheet on the unloading conveyor belt. At this time, the main frame 2 stops moving, and the servo motor 1402 is controlled to rotate in the opposite direction, so that the servo motor 1402 drives the driving gear 1403 to rotate, and the driving gear 1403 will engage and drive the second rack 1405 to slide along the fixed block 1404, thereby pulling the support seat 1407 to move through the connecting frame 1406, so that the support seat 1407 drives the anti-drop rod 1408 to move closer to each other, squeezing the two side walls of the sheet to prevent the position of the sheet from shifting. After the adjustment is completed, the servo motor 1402 is controlled to reset and rotate, thereby making the two anti-drop rods 1408 move away from the sheet. Then, as the main frame 2 moves downward, the suction cup 1205 will fit with the surface of the sheet, so that the air in the suction cup 1205 is evacuated by the pump to adsorb the sheet and move the sheet from the unloading conveyor belt to the electromagnetic platform;

[0039] The first drive motor 9 drives the first gear 10 to rotate, so that the first gear 10 engages the first rack 11, thereby driving the slider 8 to slide along the second stand 5, and then the slider 8 will drive the first workstation 6 and the second workstation 7 to move and adjust their positions. When the position of the suction cup 1205 needs to be adjusted, the second drive motor 1202 drives the second gear 1203 to move, so that the second gear 1203 engages the first rack 11 to drive the moving part 1201 to move, and the moving part 1201 will drive the electric telescopic rod 1204 and the suction cup 1205 to move. Through the coordinated work of the first drive motor 9 and the second drive motor 1202, movement and adjustment in multiple directions are achieved, which has strong flexibility, reduces the complexity of manual operation, and improves production efficiency.

[0040] Example 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1 and Example 2. When the sheet metal falls during the unloading process, it may also pose a safety hazard to the operators on the production line, which may cause personal injury or other safety accidents.

The two connecting frames 1406 are fixedly installed on the side walls of the second rack 1405 in a one-to-one correspondence. The side walls of the two connecting frames 1406 on the opposite sides are fixedly connected to the support seat 1407. The support seat 1 407 is fixedly connected to an anti-fall rod 1408, a sleeve 1413 is fixedly installed on the outside of the connecting frame 1406, an air bag 1414 is provided in the sleeve 1413, one end of the air bag 1414 is fitted with a sliding rod 1415, an air cavity 1409 is provided in the anti-fall rod 1408, a piston piece 1410 is movably connected in the air cavity 1409, the upper end of the piston piece 1410 is fixedly connected to a push rod 1411, one end of the push rod 1411 away from the piston piece 1410 extends through the anti-fall rod 1408, and the extended end of the push rod 1411 is fixedly connected to an extrusion plate 1412, and an auxiliary sleeve is provided on the outside of the push rod 1411 Spring 1416, the top end of the auxiliary spring 1416 is fixedly connected to the inner wall of the air cavity 1409, the bottom end of the auxiliary spring 1416 is fixedly connected to the piston plate 1410, the support seat 1407 is a hollow structure, the internal channel of the support seat 1407 is connected to the air cavity 1409, and the connecting hole is located below the piston plate 1410, the airbag 1414 is connected to the internal channel of the support seat 1407 through a pipe, the sliding rod 1415 on the airbag 1414 is slidably connected to the sleeve 1413, and the end of the sliding rod 1415 away from the airbag 1414 extends through the sleeve 1413 and is fixedly connected to the side plate 3.

[0041] In this technical solution, Figure 8As shown, by utilizing the setting of the push rod 1411 and the extrusion plate 1412, when the anti-fall rod 1408 moves to the bottom of the sheet, the sliding rod 1415 will squeeze the airbag 1414 in the sleeve 1413, causing the airbag 1414 to deform, thereby transporting the gas to the air cavity 1409, pushing the piston plate 1410 to move upward, so that the piston plate 1410 drives the push rod 1411 and the extrusion plate 1412 to move synchronously, and then the extrusion plate 1412 is squeezed with the bottom of the sheet, thereby improving the adsorption effect of the suction cup 1205 and thus improving production efficiency.

[0042] It uses Figure 7 and Figures 9-11 According to the technical solution shown, first, when the suction cup 1205 is adsorbed on the sheet material, the anti-drop rod 1408 is under the sheet material, and then the main frame 2 drives the suction cup 1205 to move, so that the suction cup 1205 lifts the sheet material to a certain height. At this time, the servo motor 1402 is controlled to rotate, so that the servo motor 1402 drives the driving gear 1403 to rotate, and the second rack 1405 is engaged by the driving gear 1403 to move, thereby driving the connecting frame 1406, the support seat 1407 and the anti-drop rod 1408 to move at the same time, so that the anti-drop rod 1408 moves to the bottom of the sheet material, and the connecting frame 1406 drives the sleeve 1413 to move when moving, so that the sliding rod 1415 extends. When the anti-fall rod 1408 is halfway under the sheet, the sliding rod 1415 squeezes the airbag 1414, causing the airbag 1414 to deform, thereby delivering the gas stored therein to the support seat 1407, and then the support seat 1407 delivers it to the air cavity 1409, and then uses the gas to squeeze the piston plate 1410, so that the piston plate 1410 pushes the ejector rod 1411 to move upward while squeezing the auxiliary spring 1416 to contract. When the ejector rod 1411 moves, it pushes the squeezing plate 1412 to move, so that the pressing plate 1412 moves upward to fit the bottom of the sheet, squeezing the sheet, and enhancing the adsorption effect of the suction cup 1205 on the sheet.

[0043] When the sheet is placed on the unloading conveyor roller, it is only necessary to control the anti-drop rod 1408 to move to the bottom of the sheet, and then use the servo motor 1402 to drive the driving gear 1403 to reverse, thereby driving the anti-drop rod 1408 to move. The anti-drop rod 1408 moves from the gap between the two conveyor rollers to the bottom of the sheet, and then the robot's arm drives the main frame 2 to move, and the main frame 2 drives the anti-drop rod 1408 to move, so that the anti-drop rod 1408 lifts the sheet, and the sheet can be smoothly removed from the unloading conveyor roller without using the suction cup 1205, thereby realizing the unloading and conveying of the sheet.
