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, and it has better applicability. After the suction cup body of the production line is adsorbed, it can automatically assist in cleaning the filter plate to reduce the maintenance frequency of the filter plate. However, during the unloading process of the sheet material, particulate impurities in the air and debris generated during the processing of the sheet material will adhere to the surface of the sheet material, resulting in a decrease in the sealing of the suction cup when it is adsorbed with the sheet material, which may cause the sheet material to slip or tilt during movement, affecting the stability and accuracy of the production line. In addition, the falling of the sheet material during the unloading process may pose a safety hazard to the operators on the production line, which may cause personal injury or other safety accidents.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 11 As shown, the present invention provides a technical solution: a welding line plate material unloading and conveying device, comprising: a mounting plate 1, the upper end of the mounting plate 1 is used to connect the arm end of the robot, the bottom end of the mounting plate 1 is fixedly connected to the main frame 2, and the two sides of the main frame 2 are fixedly connected to the side plates 3.

[0034] This technical solution utilizes the setting of the mounting plate 1 and the main frame 2. When in use, the mounting plate 1 is first connected to the arm end of the robot, and the mounting plate 1 and the main frame 2 are driven by the robot's arm to move above the sheet to be unloaded, and the suction cup 1205 under the main frame 2 is pressed against the sheet. The air in the suction cup 1205 is further sucked by a pump, so that the suction cup 1205 absorbs the sheet. 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 made on the basis of the above-mentioned embodiment 1. In the process of unloading the existing 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 performance of the suction cup when adsorbing the sheet, so that the sheet may slide or tilt during the unloading process, affecting the stability and accuracy of the production line. The technical solution of this invention is as follows: Figure 1-Figure 6As shown, a cleaning component of a blanking device is disclosed, wherein a first stand 4 is fixedly connected to a side wall of a side plate 3 opposite to the side plate 3, a second stand 5 is fixedly connected to the side wall of the first stand 4, a first work frame 6 is slidably connected to the side plate 3, a second work frame 7 is slidably connected to the side plate 3 on the side of the first work frame 6, a slider 8 is fixedly connected to the first work frame 6 and the second work frame 7 at one end away from the side plate 3, a first drive motor 9 is fixedly connected to the slider 8, a first gear 10 is fixedly connected to the output end of the first drive motor 9, and the first stand 4, the second stand 5, the first work frame 6 and the second work frame 7 are fixedly connected The first rack 11, the first stand 4, the first station frame 6 and the second station frame 7 above the first rack 11 are evenly connected along the X-axis direction to form a plurality of unloading mechanisms 12, the unloading mechanism 12 includes a moving member 1201 slidably arranged along the X-axis direction of the first stand 4, the first station frame 6 and the second station frame 7, the side wall of the moving member 1201 is fixedly connected to an electric telescopic rod 1204, the output end of the electric telescopic rod 1204 is fixedly connected to a suction cup 1205, and a cleaning mechanism 13 is arranged on the main frame 2 above the suction cup 1205, the second stand 5 is arranged at a right angle to the first stand 4, and the slider 8 of the second stand 5 The first rack 11 on the second stand 5 is meshed with the first gear 10, the unloading mechanism 12 also includes a second drive motor 1202 and a second gear 1203, the second drive motor 1202 is fixedly arranged on the moving member 1201, the output end of the second drive motor 1202 is fixedly connected to the second gear 1203, the second gear 1203 is meshed with the first rack 11, the cleaning mechanism 13 includes an air pump 1301, a bracket 1302 and a ventilation pipe 1303, the air pump 1301 is fixedly arranged on the main frame 2, and the air outlet end of the air pump 1301 is connected to the ventilation pipe 1303 through a hose The bottom end of the ventilation duct 1303 is fixedly connected to a bracket 1302, and one end of the bracket 1302 away from the ventilation duct 1303 is fixedly connected to the first station frame 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 station frame 6. The discs 1304 are all hollow structures, and the discs 1304 are connected to the air outlet end of the ventilation duct 1303 through a hose. A plurality of nozzles 1305 are evenly spaced on the side walls of the discs 1304, and the nozzles 1305 are connected to the discs 1304.

[0036] In this technical solution, Figure 2As shown, by using the settings of the ventilation duct 1303, the disc 1304 and the nozzle 1305, the gas is transported from the ventilation duct 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 duct 1303 is set 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 duct 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 as to fully cover every corner of the surface of the sheet material and enhance the cleaning effect. At the same time, the disc 1304 is larger than the diameter of the suction cup 1205, and thus to a certain extent, the suction cup 1205 can be prevented from being damaged.

[0037] Its use is as Figure 1 and Figure 3-Figure 6 The technical solution shown, first, after the sheet is welded, it flows to the unloading conveyor belt, and the unloading conveyor belt conveys the sheet to the bottom of the suction cup 1205. At this time, by moving the main frame 2, the main frame 2 drives the side plate 3, the first stand 4, the second stand 5, the first station frame 6 and the second station frame 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 inclined, the air flow cleans the sheet;

[0038] Then, as the main frame 2 moves downward, the two ends of the anti-drop rod 1408 are first 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 mesh 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 approach each other, squeeze 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 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 the sheet is moved 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 with the first rack 11, thereby driving the slider 8 to slide along the second stand 5, and then the slider 8 drives the first work frame 6 and the second work frame 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 with the first rack 11 to drive the moving part 1201 to move, and the moving part 1201 drives 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 realized, which has strong flexibility, reduces the complexity of manual operation, and improves production efficiency.

[0040] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2.

[0041] In this technical solution, Figure 8As shown, by using 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 air bag 1414 in the sleeve 1413, causing the air bag 1414 to deform, thereby delivering 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] Its use is as Figure 7 and Figure 9-11 According to the technical solution shown in the figure, 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, and 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 supporting 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.

[0043] When the sheet is placed on the unloading conveying 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.
