The movement control part 212 may control the movement of the suction nozzle 211. In some embodiments, when the large card 400 needs to be suctioned, the movement control part 212 may control the suction nozzle 211 to move upward until the suction nozzle 211 contacts the large card 400. After the suction nozzle 211 suctions the large card 400 is completed, the movement control part 212 may control the suction nozzle 211 to move downward until the large card 400 moves to a preset position. In some embodiments, the movement distance of the movement control member 212 and/or the suction nozzle 211 may be detected in order to improve the control accuracy in controlling the movement of the suction nozzle 211, and to prevent the suction nozzle 211 from excessively increasing an unnecessary stroke to reduce efficiency. In some embodiments, a sensor may be utilized to detect the distance of movement of the motion control component 212 and/or the suction nozzle 211. In some embodiments, the movement control component 212 may employ one or more of an air cylinder, a hydraulic cylinder, an electric push cylinder, a drive train, or a linkage assembly.

In some embodiments, the suction nozzle 211 may employ a vacuum chuck, the suction control component may employ a vacuum extractor, and the suction control component may be in communication with the suction nozzle 211 through a conduit. When the suction nozzle 211 contacts the large card 400, the suction control part may suction the large card 400 by sucking air to form a vacuum in the suction nozzle 211. After the large card 400 is moved in place, the suction control part may blow air into the suction nozzle 211 to release the vacuum state, so that the large card 400 is separated from the suction nozzle 211. In some embodiments, the suction control component may be disposed within the chassis 600.

In some embodiments, the sensor, the motion control unit 212, and the suction control unit may be coupled to a processor, the distance signal detected by the sensor may be sent to the processor, the processor may process the distance signal, and when the distance signal meets a set threshold, the processor may control the motion control unit 212 and the suction control unit to perform a corresponding action. For example, when the distance signal of the upward movement of the suction nozzle 211 detected by the sensor meets a set threshold, the processor may control the suction control unit to perform an action so that the suction nozzle 211 attracts the large card 400, and then the processor may control the movement control unit 212 to perform an action so as to drive the suction nozzle 211 to move downward. When the distance signal of the downward movement of the suction nozzle 211 detected by the sensor satisfies a set threshold, the processor may control the suction control part to perform an action such that the suction nozzle 211 is separated from the large card 400.

Fig. 5 is a schematic structural view of an exemplary large card pushing assembly shown in accordance with some embodiments of the present description. Fig. 6 is a top view of an exemplary large card pushing assembly shown according to some embodiments of the present description. As shown in fig. 5 and 6, the large card pushing assembly 220 includes a large card gripping member 221, a clamping driving member 222, and a pushing driving member 223.

In some embodiments, the large clip fastening member 221 may include at least one clip portion that can be opened or closed. In some embodiments, the large card gripping member 221 may grip at least two points on one end of the large card 400 to improve stability of the grip and prevent the large card gripping member 221 from rotating relative to the large card 400.

The clamp driving member 222 may be used to control the clamp to open or close. In some embodiments, the clamp actuation member 222 may be communicatively coupled to a processor. When the suction nozzle 211 moves down to a preset position, the processor may control the clamping driving part 222 to perform an action, and the clamping driving part 222 may control the clamping part to clamp the large card 400.

In some embodiments, the end of the fixing block 2211 near the large card 400 is provided with a limiting structure, and the limiting structure can limit the relative position of the fixing block 2211 and the large card 400, so as to limit the stress area when the large card 400 is clamped. The problem that the stressed part of the large card 400 is easy to damage or fall off due to the fact that the stressed area is too small is avoided, or the problem that the clamped part of the large card 400 is difficult to cut due to the fact that the stressed area is too large is avoided. In some embodiments, the limiting structure may be a protrusion 2214 provided on the fixed block 2211, and a groove 2213 for avoiding the protrusion 2214 is provided on the movable block 2212. In some embodiments, the minimum distance of the protrusion 2214 from the end surface of the fixation block 2211 may be less than or equal to the minimum width of the large card 400 after cutting, and greater than or equal to half the minimum width of the large card 400 after cutting.

The pushing driving part 223 may be used to control the movement of the clamping driving part 222, and the clamping driving part 222 may drive the large card clamping part 221 and the large card 400 to move synchronously.

The large card receiving stand 230 may be used to support a large card 400. In some embodiments, when the suction nozzle 211 moves down to the point where the large card 400 falls onto the large card receiving stage 230, it may be considered that the large card 400 moves into place. In some embodiments, the large card receiving platform 230 is provided with a recess that allows the suction nozzle 211 to be avoided. In some embodiments, the sled 2231 may be disposed on the large card receiving platform 230. In some embodiments, the large card gripping member 221 may be provided on the large card receiving stage 230. In some embodiments, the large card receiving bay 230 may be disposed on the support plate 500 by a post. In some embodiments, as shown in fig. 4, the large card receiving platform 230 is provided with a guide groove 2216, and as shown in fig. 7, the fixed block 2211 is provided with a guide block 2215 slidably connected with the guide groove 2216, and the guide block 2215 can slide in the guide groove 2216. The guide groove 2216 is parallel to the moving direction of the large card 400, i.e., the length direction of the large card 400. By the cooperation of the guide groove 2216 and the guide block 2215, the moving accuracy of the large card 400 can be improved.

The large card positioning block 240 is slidably disposed on the large card receiving stage 230. In some embodiments, the sliding direction of large card positioning block 240 may be perpendicular to the moving direction of large card 400. When the large card positioning block 240 approaches the large card 400, the large card positioning block 240 can limit the position of the large card 400.

Fig. 8 is a schematic structural view of an exemplary large card positioning block shown in accordance with some embodiments of the present description. As shown in fig. 8, a large card accommodating groove 242 and a slant surface 241 are provided on a side of the large card positioning block 240 facing the large card 400.

The large card receiving groove 242 may be used to receive the large card 400, limiting edge portions of both sides of the large card 400 to the large card receiving groove 242. When the large card 400 moves, the edge of the large card 400 can be prevented from being tilted upwards to influence the accuracy in cutting. In some embodiments, the height of the large card receiving slot 242 may be slightly greater than the thickness of the large card 400, avoiding the large card receiving slot 242 from causing compression 2 to the edge of the large card 400 to damage the large card 400, or avoiding the large card 400 from being difficult to move or from wearing.

Inclined surface 241 is provided on a side of large card positioning block 240 facing large card 400. Inclined surface 241 is connected between large card receiving groove 242 and the side of large card positioning block 240 facing large card 400. In some embodiments, after the large card 400 is dropped onto the large card receiving stage 230, the large card positioning block 240 moves in a direction approaching the large card 400, and if the large card 400 is inclined with respect to the edge of the large card positioning block 240, the position of the large card 400 can be corrected to meet the requirement of cutting under the pushing of the large card positioning block 240. Since the large card 400 moves downward and passes through the bearing 120, the side of the large card 400 is pushed upward and is liable to be tilted upward. When the side edge of the large card 400 is tilted upward, the inclined surface 241 can apply downward pressure to the tilted portion of the large card 400 during the movement process, so that the side edge portion of the large card 400 can enter the large card accommodating groove 242, and the large card 400 is prevented from being bent to affect the cutting quality.

The large card cutting mechanism 300 includes a cutting blade and a cutting blade drive mechanism.
