In view of the above, the present utility model proposes a conveying apparatus 100.

Referring to fig. 1 to 9, in the embodiment of the present utility model, the conveying device 100 includes a first conveying structure 10 and an induction component 30, the first conveying structure 10 is provided with at least one quality inspection station 131, the quality inspection station 131 is provided with a blocking member 133 and a processor 111, the blocking member 133 is electrically connected to the processor 111, the blocking member 133 is liftably disposed at the quality inspection station 131, and is used for blocking or avoiding the workpiece 200; the sensing component 30 is arranged at the quality inspection station 131 and below the workpiece 200, the sensing component 30 and the blocking piece 133 are sequentially arranged along the transmission direction of the quality inspection station 131, the sensing component 30 comprises an infrared sensor 31 and a photosensitive sensor 33, and the infrared sensor 31 and the photosensitive sensor 33 are electrically connected with the processor 111.

It can be appreciated that the first conveying structure 10 may be provided with one quality inspection station 131, or a plurality of quality inspection stations 131 may be sequentially arranged, and the area of the quality inspection station 131 on the first conveying structure 10 may be slightly larger than the area of the workpiece 200 or the area of a tray carrying the workpiece 200, so that a plurality of workpieces 200 may be placed on the first conveying structure 10 at intervals for quality inspection, thereby realizing automatic assembly line operation. At this time, by providing the processor 111 and the blocking member 133 on the quality inspection station 131, the blocking member 133 can be used to block the movement of the workpiece 200 to be inspected on the first conveying structure 10 when inspecting the quality of the workpiece 200 to be inspected placed on the first conveying structure 10, so that the workpiece 200 to be inspected can be stably stopped on the first conveying structure 10 to be inspected by a worker or a detecting device along the conveying direction facing away from the first conveying structure 10. When the workpiece 200 passes the quality inspection, the processor 111 may be used to lower the blocking member 133 blocking the workpiece 200 so that the passing quality inspection workpiece 200 sequentially passes the subsequent quality inspection station 131 to the next processing step for processing. At this time, by arranging the sensing assembly 30 at the quality inspection station 131, the sensing assembly 30 and the blocking member 133 are sequentially arranged along the transmission direction of the quality inspection station 131, so that the workpiece 200 passing the quality inspection can be moved to the upper side of the sensing assembly 30 when moving to the next quality inspection station 131, at this time, the infrared sensor 31 and the photosensitive sensor 33 on the sensing assembly 30 can quickly identify the workpiece 200 passing by due to the change of light, and can send out a signal to enable the controller to control the blocking member 133 on the quality inspection station 131 to descend so as to avoid the workpiece 200 passing by, thereby ensuring that the workpiece 200 passing the quality inspection can be well conveyed to the next processing procedure by the first conveying structure 10; when the workpiece 200 moves away from the sensing assembly 30, the photosensitive sensor 33 can quickly recognize that the workpiece 200 leaves the sensing assembly 30 due to the change of light, and the infrared sensor 31 can receive the reflected light beam to send a signal when the workpiece 200 is away from the blocking member 133 after the workpiece 200 is removed, and the processor 111 can control the blocking member 133 to lift again. Meanwhile, when the first conveying structure 10 is provided with the plurality of quality inspection stations 131, the plurality of quality inspection stations 131 are sequentially arranged on the first conveying structure 10, so that the workpiece 200 can just move to the upper part of the induction component 30 of the next quality inspection station 131 when being far away from the blocking piece 133 of the quality inspection station 131, further, the fact that the workpiece 200 passing through quality inspection can be sequentially conveyed to the next station for processing through the plurality of quality inspection stations 131 on the first conveying structure 10 is effectively guaranteed, and the automatic operation of the conveying device 100 is guaranteed.

When the sensing assembly 30 is normal, the workpiece 200 passing the quality inspection moves to the upper side of the sensing assembly 30, at this time, the emitting path and the reflecting path of the infrared sensor 31 can be shortened under the action of the workpiece 200, so that the infrared sensor 31 can quickly send a first signal indicating that the blocking member 133 descends to the processor 111, the photosensitive sensor 33 can also quickly sense the darkening of light to send a first signal indicating that the blocking member 133 descends, at this time, the processor 111 can be controlled to control the blocking member 133 to descend when receiving any first signal, so that the blocking member 133 avoids the workpiece 200 to move; after the workpiece 200 moves to a position far away from the sensing assembly 30, at this time, the transmitting path and the reflecting path of the infrared sensor 31 can be prolonged due to the removal of the workpiece 200, so that the sensing time of the infrared sensor 31 is prolonged, the photosensitive sensor 33 can quickly send out a second signal due to the brightening of light, at this time, the processor 111 can start the timer when receiving the second signal of the photosensitive sensor 33, and control the timer to stop when the infrared sensor 31 receives the reflected light and send out the second signal, and record the preset time, and control the blocking member 133 to rise when the processor 111 receives two second signals, at this time, the workpiece 200 is conveyed to a position far away from the blocking member 133 by using the first conveying structure 10 within the time when the infrared sensor 31 receives the reflected light, so that the blocking member 133 can be lifted after the workpiece 200 leaves the quality inspection station 131, so as to ensure the continuous operation of the conveying device 100.

When the infrared sensor 31 fails, the processor 111 may detect that the infrared sensor 31 fails to make the photosensitive sensor 33 send the second signal, trigger the timer to start, and make the timer trigger the analog annunciator to send the second signal after a preset time. At this time, after the workpiece 200 passing the quality inspection moves above the sensing assembly 30, the photosensitive sensor 33 can quickly sense that the light is darkened and send a first signal to instruct the processor 111 to control the blocking member 133 to descend so as to avoid the workpiece 200; when the quality inspection workpiece 200 leaves the sensing assembly 30, the photosensitive sensor 33 can quickly sense that the light is lightened and send a second signal to the processor 111, at this time, the second signal triggers the timer to start timing, and triggers the analog signal generator to send a second signal to the control unit of the processor 111 after a preset time, so that the processor 111 can receive two second signals and further control the blocking member 133 to lift, and after the preset time, the first conveying structure 10 can stably move the workpiece 200 to a position far away from the blocking member 133, so that the smooth operation of the conveying device 100 can be realized by utilizing the coordination cooperation between the photosensitive sensor 33 and the processor 111 when the infrared sensor 31 fails, the workpiece 200 can be ensured to move to the next processing procedure smoothly, and the structural reliability and practicality of the conveying device 100 are further improved.

When the photosensor 33 fails, the processor 111 may detect that the photosensor 33 fails to send a second signal, and may trigger the analog annunciator to send the second signal when the infrared sensor 31 sends the second signal. At this time, after the workpiece 200 passing the quality inspection moves above the sensing assembly 30, the shortening of the emitting path and the reflecting path of the infrared sensor 31 may rapidly signal the processor 111 to control the barrier 133 to descend so as to avoid the workpiece 200; and when the quality inspection workpiece 200 leaves the sensing assembly 30, the emitting path and the reflecting path of the infrared sensor 31 are prolonged, so that the sensing time of the infrared sensor 31 is prolonged, the first conveying structure 10 can be made to move the workpiece 200 to a position far away from the blocking member 133 in the sensing time, and when the infrared sensor 31 receives the reflected light to send a second signal to the processor 111, the second signal can be made to trigger the analog signal to send the second signal, so that the processor 111 can control the blocking member 133 to lift after receiving the two second signals, and therefore, when the photosensitive sensor 33 fails, the smooth operation of the conveying device 100 can be realized by utilizing the coordination between the infrared sensor 31 and the processor 111, the workpiece 200 can be ensured to be smoothly moved to the next processing procedure, and the structural reliability and the practicability of the conveying device 100 are further improved.
