DETAILED DESCRIPTION

[0040] The utility model will be described in further detail below in combination with the drawings and specific embodiments:

[0041] The embodiment aims to provide a computer vision recognition positioning device, which is mainly used for "open door type" vending machine, and aims at the problem that the "open door type" vending machine cannot comprehensively monitor the number and position state of goods in the goods shelf 101.

[0042] A computer vision recognition positioning device, such as Figure 1 , comprises a vending machine body 1, a lifting mechanism, a translation mechanism, an angle adjusting mechanism and a camera 10; the lifting mechanism comprises a lead screw 2, a screw sleeve 3 and a drive mechanism 4; the lead screw 2 is vertically arranged on the left and right sides of the goods shelf 101 of the vending machine, and the screw sleeve 3 is threadedly connected to the lead screw 2.

[0043] The drive mechanism 4 is simultaneously transmissionally connected with the lead screws 2 on the left and right sides, and the drive mechanism 4 is used to drive the rotating lead screw 2 to drive the screw sleeves 3 on the left and right sides to synchronously ascend or descend; the drive mechanism 4 comprises a transmission shaft 401, a bevel gear 402, a transmission gear set 403 and a drive motor 404; the transmission shaft 401 is horizontally arranged at the bottom of the vending machine, the bevel gears 402 are fixedly sleeved on the two ends of the transmission shaft 401 and the bottoms of the two lead screws 2, and the transmission shaft 401 is transmissionally connected with the two lead screws 2 through the bevel gears 402 to realize reverse transmission; since the directions of rotation of the two lead screws 2 are opposite, the screw threads of the two lead screws 2 are opposite, so that the two screw sleeves 3 can synchronously ascend or descend; as Figure 6The middle part of the transmission shaft 401 is in transmission connection with the driving motor 404 through the transmission gear set 403, so that one driving motor 404 controls the synchronous rotation of the two lead screws 2, thereby realizing the synchronous rising or falling of the two screw sleeves 3. In other embodiments, the driving mechanism 4 can also adopt two same type motors, and the synchronous rotation of the two lead screws 2 is realized through the same control instruction.

[0044] The translation mechanism is arranged between the two screw sleeves 3 and rises or falls with the two screw sleeves 3. Figure 2 and Figure 3 The translation mechanism includes a sliding rail 5, a sliding block 6, a translation motor 7 and a translation pulley 8. The left and right ends of the sliding rail 5 are fixedly connected with the two screw sleeves 3 and are located in front of the shelf 101. The lower end surface of the sliding rail 5 is horizontally provided with a track 9.

[0045] The sliding rail 5 is slidably provided with the sliding block 6. As shown in FIG. 4, the sliding block 6 includes a sliding part 601 and a mounting part 602. The mounting part 602 is fixed on the lower surface of the sliding part 601. The sliding part 601 is mainly used to form a sliding connection with the sliding rail 5. The mounting part 602 is mainly used to carry the translation motor 7 and the angle adjusting mechanism. The sliding part 601 is provided with a lower opening sliding groove 603 matched with the sliding rail 5. The sliding part 601 is slidably sleeved on the sliding rail 5 through the sliding groove 603. The track 9 is vertically fixed on the lower end surface of the sliding rail 5 and movably inserted into the lower opening of the sliding groove 603. The track 9 has a gap with the sliding groove 603 and does not contact with the sliding groove 603.

[0046] The translation motor 7 is mounted on the mounting part 602. The translation pulley 8 is fixedly sleeved on the rotating shaft of the translation motor 7. The wheel surface of the translation pulley 8 contacts and abuts against the track 9, and forms a driving force to make the sliding block 6 move horizontally along the sliding rail 5.

[0047] In order to further improve the compactness of the structure and optimize the stress, the sliding part 601 is distributed on the left and right sides of the mounting part 602. The translation motor 7 is mounted on the lower surface of the mounting part 602. The rotating shaft of the translation motor 7 rotates from bottom to top through the mounting part 602. The rotating through means that the rotating shaft passes through the mounting part 602 and can still rotate normally. The translation pulley 8 is horizontally arranged above the mounting part 602 and located between the two sliding parts 601, thereby improving the compactness of the structure. The translation motor 7 is located behind the angle adjusting mechanism. The translation pulley 8 forms a contact friction with the rear end surface of the track 9, so that the weight of the mounting part 602 on the front and rear sides is relatively balanced.

[0048] In order to further improve the driving effect of the track 9 and the translation pulley 8, Figure 5 The rear end surface of the track 9 is provided with a rack. The translation pulley 8 is a gear structure and is engaged with the rack of the track 9. This directly avoids the situation of slipping, improves the reliability of driving, ensures the accuracy of driving, and is convenient for control.

[0049] As Figure 3 And Figure 4 The angle adjusting mechanism includes a rotating seat 11, a rotating shaft 12, a rotating plate 13 and a rotating motor 14. The rotating seat 11 is installed on the lower surface of the mounting portion 602 of the sliding block 6, and the lower surface of the rotating seat 11 is provided with a rotating groove. The upper end of the rotating plate 13 is fixedly connected with the rotating shaft 12, and the rotating shaft 12 is rotatably arranged in the rotating groove of the rotating seat 11. One end of the rotating shaft 12 is in transmission connection with the rotating motor 14, and the rotating motor 14 is fixed on the lower surface of the mounting portion 602. The lower end of the rotating plate 13 is fixedly connected with the camera 10. When the rotating shaft of the rotating motor 14 rotates, the camera 10 can be adjusted in angle along the front and back directions, so as to change the orientation and field of view of the camera 10.

[0050] During the idle period of customer shopping, the camera 10 can adjust the orientation to the inside of the shelf 101 through the angle adjusting device, and move up and down and left and right through the lifting mechanism and the translation mechanism, realize the comprehensive visual coverage of the inside of the shelf 101, monitor and obtain the quantity and position state of the goods in the inside of the shelf 101, accurately monitor the position and quantity of each good, ensure the timely update of the inventory information, can timely find the situation of out-of-stock or overstock, make reasonable inventory adjustment, reduce the sales loss caused by out-of-stock and the capital occupation caused by overstock, and ensure that the inventory is at the best level. During the period of customer shopping, that is, after the customer scans the code and interacts, the camera 10 will return to the top of the vending machine and re-orient to the area where the goods are taken out of the shelf 101, and the existing "open door type" unmanned vending machine generally works normally.
