[0002] A material rack, also known as a goods shelf, is the main storage equipment inside a material warehouse, used to store small batches of various materials, including materials bundled and packaged in pieces. Using various material racks facilitates the classification, storage, receipt, and dispatch of materials, and can reduce material losses and improve the utilization rate of the storage capacity. General material racks include layer racks, layer grid racks, drawer racks, and cabinet racks, etc. Layer racks are further divided into single-sided layer racks and double-sided layer racks.
[0003] The existing SMT material rack includes an outer frame, a layered board, and limit blocks. Among them, the layered board is fixedly installed inside the outer frame, and then the limit blocks are evenly distributed on the layered board and the outer frame. The accessories are positioned and stored through the upper and lower layered limit blocks. Among them, the accessories are placed manually or operated by a robotic arm. The operation efficiency of the robotic arm is high, and it is also convenient to place the accessories in higher empty positions.
[0004] For the above technical conditions, there are still defects: the existing material rack cannot record the presence or absence status of items in each individual small grid. When the robotic arm is working continuously, it may cause the items not to be placed on the material rack due to insecure clamping. Then, the robotic arm will not load the same position again, resulting in gaps in the item storage on the material rack.
[0005] Based on this, the utility model designs an SMT intelligent material rack to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0027] The following will be further described in detail with reference to the attached Figures 1-3 This application will be further described in detail.
[0028] Refer to Figure 1 And Figure 2 A SMT intelligent material rack includes an outer frame 1, a laminated board 2 and a limit block 3. Both sides of the top of the outer frame 1 are fixedly connected with support bases 4. The outside of the support base 4 is fixedly connected with a driving motor 5. The driving motor 5 is a stepping motor, which can control the height of the counting board 10 more precisely. A transmission shaft 6 is rotatably connected between the two support bases 4. One end of the transmission shaft 6 is coaxially fixed with the output shaft of the driving motor 5. Two runners 7 are fixedly connected to the transmission shaft 6. Cables 8 are fixedly connected to both of the two runners 7. The bottom end of the cable 8 is fixedly connected with a positioning block 9. The positioning block 9 is fixedly connected with a counting board 10. A height sensor is also provided on the counting board 10 to monitor the height of the counting board 10 in real time. The laminated board 2 divides the outer frame 1 into multiple layers. When the moving distance of the counting board 10 is the same as the distance between the two laminated boards 2, the monitoring of the next layer is carried out. Multiple partition bars 12 are provided at the bottom of the counting board 10.
[0029] Refer to Figure 1 And Figure 2, the limiting blocks 3 are evenly distributed on the layered plate 2. The gaps between the limiting blocks 3 are the same as the gaps between the partition bars 12. Multiple gaps are formed between the multiple partition bars 12. When the counting plate 10 moves in the vertical direction, the gaps can correspond one by one to the small grids formed between the four groups of limiting blocks 3. Inductive probes 13 are provided on the partition bars 12. The inductive probes 13 are distributed in pairs on the partition bars 12. The inductive probes 13 distributed in pairs are adapted to each other. Infrared connection is used between the two inductive probes 13, and the connection between them can be disconnected when an item passes between the two inductive probes 13, thus achieving the recording effect.
[0030] Refer to Figure 2 With Figure 3 , a sensor 14 is provided on the other side of the counting plate 10. The sensor 14 is adapted to the inductive probe 13. When loading one layer, when the two sensors 14 record a long time interval and send an abnormal signal, it indicates that there is an abnormality in the mechanical arm clamping the item at this time.
[0031] Sliding seats 11 are fixedly connected to both sides of the counting plate 10. The sliding seats 11 are slidably connected to the outer frame 1. Through the sliding connection between the sliding seats 11 and the outer frame 1, the counting plate 10 can move more stably in the vertical direction, achieving a better control effect.
[0032] The number of layered plates 2 is not less than seven groups. The seven groups of layered plates 2 are all fixedly installed inside the outer frame 1. The number of limiting blocks 3 is not less than sixteen groups. Two groups of limiting blocks 3 are respectively fixed at the top and bottom of the layered plate 2 to place more items, thereby increasing the storage capacity of the rack.
[0033] The implementation principle of this embodiment is as follows:
[0034] When the rack is loading goods, start the drive motor 5 to drive the transmission shaft 6 to reverse, so that the cable 8 is loosened on the runner 7. Then the counting plate 10 moves downward under the action of gravity. The counting plate 10 stops moving when it is flush with the bottom inner wall of the outer frame 1 at the bottom of the partition bar 12. Then place the item on the bottom layer through the mechanical arm. When the item passes between the two inductive probes 13, its signal is blocked, and a record is formed through the sensor 14 (when the two sensors 14 record a long time interval and send an abnormal signal). When each sensor 14 has a record, that is, the bottom layer is full; then start the drive motor 5 to drive the transmission shaft 6 to rotate forward, so that the cable 8 is wound on the runner 7, driving the counting plate 10 to move upward a certain distance (the distance between two layered plates 2), and turn off the drive motor 5 to make the counting plate 10 stop moving. At this time, reset the record of the sensor 14 to make it record the loading of the second layer. The mechanical arm continues to load the second layer. When each sensor 14 has a record, that is, the second layer is full, and so on until the entire rack is full.
