Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warehouse material management, and particularly relates to an SMD tray access sensing light-up rack. BACKGROUND

[0002] The SMD tray is a common packaging form of reel material in the SMT electronic manufacturing industry. The existing traditional tray storage rack has the following problems. Some of the existing traditional tray storage racks stack multiple trays in the same storage position or the same tray box, so that it is difficult to realize separate fine control of the access of each tray. Some of the existing traditional tray storage racks set up independent storage positions for each tray and number each storage position, so that personnel find the tray by searching for the storage position number, and the operation efficiency is low. Some of the existing tray rack schemes add a light-up guiding device to each tray rack with an independent storage position, that is, each independent storage position is provided with an LED indicator light and a storage position code. The tray code and the storage position code are scanned by a code scanning device respectively to realize one-to-one binding of the tray and the storage position during storage. The LED indicator light is lighted up to remind the storage position during tray taking, so that the operation efficiency is obviously improved, especially the tray taking efficiency. However, since each storage position lacks a sensing device capable of automatically detecting the storage and taking of the tray, and the storage positions of the rack scheme are usually dense, it is difficult to avoid the phenomenon of incorrect storage or incorrect taking of the tray.

The control system reads the state information of the Hall sensor 10 through industrial bus communication and controls the LED lamp beads 19 and the LED lamp strip 12.

[0036] The present application comprehensively applies the gravity of the tray 36, the magnetic attraction of the reset magnet 28, the magnetic field of the induction magnet 27, and the magnetic field induction principle of the Hall sensor 10 to detect the tray storage and retrieval action. The specific working principle is as follows: when the tray 36 is stored in any storage position, the rotating wheel one 25 or the rotating wheel two 26 is used to receive the gravity of the tray 36, and the branch is pressed to rotate. The reset magnet 28 of the rotating wheel one 25 or the rotating wheel two 26 is separated from the inner wall of the layer plate 21 and leaves the preset position. The induction magnet 27 of the rotating wheel one 25 or the rotating wheel two 26 approaches the Hall sensor 10 at the back of the LED lamp plate 11 through the inductor gap 38 of the layer plate 21. The Hall sensor 10 generates an induced voltage signal, and the control system receives and processes the change of the induced voltage signal to complete the automatic detection of the tray 36 storage action. When the tray 36 is taken out, the branch for receiving the gravity of the tray 36 is no longer pressed, and the reset magnet 28 automatically returns to the preset position under the action of magnetic attraction. The induction magnet 27 is away from the Hall sensor 10, and the Hall sensor 10 disappears. The control system receives and processes the change of the induced voltage signal to complete the automatic detection of the tray 36 retrieval action.

[0037] In the above process, the control system will send a signal to the LED lamp plate 11. After the tray 36 is stored, the control system will light up the LED lamp beads 19 corresponding to the storage position on the LED lamp plate 11 to prompt the operator that the storage is successful. Before the tray 36 is taken out, the control system will first light up the LED lamp beads 19 corresponding to the storage position on the LED lamp plate 11. After the tray 36 is taken out, the control system will extinguish the LED lamp beads 19 corresponding to the storage position on the LED lamp plate 11 to prompt the operator that the retrieval is successful.

[0038] In some scenarios, the tray 36 may not be correctly stored, such as when the tray 36 is directly stored without first performing a code scanning operation, resulting in the control system being unable to obtain the material information of the stored tray 36. The control system will send a signal to the LED lamp plate 11 and the LED lamp strip 12 at the same time. After receiving the signal, the LED lamp plate 11 lights up the LED lamp beads 19 corresponding to the storage position to a pre-defined alarm color, and the LED lamp strip 12 flashes an alarm.

[0039] In some scenarios, the operation of not taking out the tray 36 correctly will also occur, such as taking out the tray 36 in the storage position with the LED lamp bead 19 not lit during the taking operation, that is, the tray 36 in the storage position is not in the taking task. The control system will send signals to the LED lamp plate 11 and the LED lamp strip 12 at the same time. After receiving the signals, the LED lamp plate 11 lights up the LED lamp bead 19 corresponding to the storage position to a pre-defined warning color, and the LED lamp strip 12 flashes a warning after receiving the signals.

[0040] The limiting ribs 35 are arranged on both sides of each dispensing gap 27 on the layer plate 21 to inhibit the inclination of the tray 36 and prevent the detection failure caused by the pressing of the rotating wheel I 25 or the rotating wheel II 26 of the adjacent storage position when the tray 36 is stored, thereby effectively improving the operation reliability. In addition, the adjacent dispensing gaps 27 are designed to be staggered in height, and the three branches of the rotating wheel I 25 and the rotating wheel II 26 are designed to be different in angle and length, so as to realize the staggered storage of the tray 36 in height, thereby facilitating the taking operation of the workers during the dense storage.

[0041] The light bar assembly 6 is installed on the outer side of the layer plate 21 in a modular manner. When troubleshooting, the light bar is taken down for replacement after the light bar fixing bolt 8 is screwed out, so that the operation is convenient and the waiting time for troubleshooting is reduced.

[0042] The specific embodiments described herein are merely illustrative of the spirit of the present application, and those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
