Plate loading and unloading, as a key pre-process of numerical control cutting machine processing, directly affects the overall production efficiency and quality.

[0031] Referring to Figure 1 , Figure 3 and Figure 4The upper side of the support table 4 is provided with an alignment assembly that can align the plate to be fed. The alignment assembly comprises positioning plates 42 arranged on the support table 4. Multiple sets of positioning plates 42 are matched to each other to move towards the middle, which can push the plate to the center and arrange the front and back sides in order, thereby facilitating feeding. The rear surface of the positioning plate 42 is fixedly connected to the connecting plate 48 near the upper side of the support table 4, which drives the positioning plate 42 to move. The end of the connecting plate 48 away from the positioning plate 42 is fixedly connected to the cross guide block 47, which drives the connecting plate 48 to move. The cross guide block 47 is arranged in a cross shape, which is matched with the sliding groove 49, thereby stably supporting the cross guide block 47 to move, and stably moving the positioning plate 42. The top end of the support table 4 is provided with the sliding groove 49 near the lower side of the connecting plate 48, which provides a moving space for the cross guide block 47. The sliding groove 49 is slidably connected with the cross guide block 47 and is matched. The bottom end of the cross guide block 47 is fixedly connected to the guide plate 44, which is arranged in two groups. The bottom end of the support table 4 is fixedly connected to the fixed plate 43, which is arranged in multiple groups. The front surface of the fixed plate 43 is fixedly connected to the servo motor 41, which drives the bidirectional threaded rod 45 to rotate. The output shaft of the servo motor 41 penetrates the fixed plate 43, and the rear surface is fixedly connected to the bidirectional threaded rod 45, which is threadedly connected with the two guide plates 44, thereby driving the two guide plates 44 to move in opposite directions at the same time. The front and rear ends of the bidirectional threaded rod 45 are rotatably connected with the corresponding fixed plate 43. The bidirectional threaded rod 45 is supported by the two fixed plates 43, and the positioning rod 46 is supported by the other two fixed plates 43.

[0032] Referring to Figure 2 , Figure 3 and Figure 4 , the bidirectional threaded rod 45 penetrates and is threadedly connected in the middle of the guide plate 44. The fixed plate 43, the sliding groove 49 and the positioning plate 42 are arranged in four groups, and the four groups are arranged at the four corners of the support table 4. The positioning rod 46 is fixedly connected between the other two fixed plates 43 below the support table 4 and is slidably connected with the guide plate 44, thereby stably supporting the guide plate 44 to move. The positioning rod 46 penetrates and is slidably connected in the middle of the guide plate 44. The bidirectional threaded rod 45 and the positioning rod 46 are symmetrically arranged with the center line of the guide plate 44 as the axis of symmetry. The bidirectional threaded rod 45 and the positioning rod 46 are arranged on the left side and the right side of the guide plate 44, respectively. The top ends of the two guide plates 44 are fixedly connected with the two cross guide blocks 47 on the left and right sides, respectively, and are symmetrically arranged.

[0033] Working principle: in use, first, the power supply and switch of the electric equipment in the device are connected, when preparing to load the plate, start the cleaning assembly, the fan 31 is connected to the external power supply and switch and starts to work, producing strong airflow, the airflow flows along the L-shaped air pipe 32, reaches the dispersion pipe 33 on both sides of the bottom end of the air pipe 32, the dispersion pipe 33 uniformly disperses the airflow to the front and rear, and guides it to the inclined air nozzle 34, the inclined air nozzle 34 blows the airflow at a specific angle to the surface of the plate below the suction cup 21, blows the dust on the plate to the right, effectively cleans the dust that may affect the adsorption effect of the suction cup 21, improves the sealing between the suction cup 21 and the plate, enhances the adsorption force of the suction cup 21, and lays a foundation for subsequent stable grabbing of the plate. At this time, the suction cup 21 can stably adsorb the neatly arranged plate, and then the suction cup 21 and the adsorbed plate can be moved to the machining area of the numerical control cutting machine to complete the plate loading operation and prepare for the subsequent machining process.

[0034] After the plate is placed on the support table 4, the servo motor 41 on the fixed plate 43 at the bottom end of the support table 4 can be started. The output shaft of the servo motor 41 rotates to drive the synchronous rotation of the two-way threaded rod 45 connected thereto. Since the two-way threaded rod 45 is threadedly connected with the guide plate 44, when the two-way threaded rod 45 rotates, the two guide plates 44 will move simultaneously. The cross guide block 47 is connected to the top end of the left and right sides of the guide plate 44, and the cross guide block 47 is slidably connected with the sliding groove 49 opened at the top end of the support table 4, which ensures the stability of the guide plate 44 during movement. The movement of the guide plate 44 drives the cross guide block 47 connected thereto to slide in the sliding groove 49, thereby driving the connecting plate 48 and the positioning plate 42 to move. The positioning plate 42 has four groups, which are arranged at the four corners of the support table 4. When the positioning plate 42 moves, the multiple positioning plates 42 cooperate with each other to gradually move towards the center, pushing the plate to be loaded on the support table 4 to the center position and arranging the plate neatly on the front and rear sides, which reduces the amount of physical labor consumed by manual alignment of the plate by the workers. At the same time, the neatly arranged plate also facilitates subsequent loading operation, for example, when the suction cup 21 is used for grabbing, since the position of the plate is neat and uniform, the suction cup 21 can more accurately and stably adsorb the plate, effectively improving the success rate and speed of loading, and greatly improving the efficiency and quality of the plate loading and unloading work of the numerical control cutting machine.
