[0017] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a shelf inventory robot, comprising a storage shelf 1, a spotlight 2 and a triangular light receiving block 21, a collection camera 3 is provided on one side of the storage shelf 1, a transverse driving trolley 4 is provided above the collection camera 3, a side wall of the transverse driving trolley 4 is fixedly connected to a limited position connecting rod 5, a side wall of the storage shelf 1 is fixedly connected to a supporting track plate 6, the transverse driving trolley 4 slides on the top of the supporting track plate 6, and a horizontal position adjustment plate 7 is slidably connected to one side of the storage shelf 1.
[0018] In this embodiment: the spotlight 2 is installed at the top of the support frame of the storage shelf 1, and the triangular light receiving block 21 is installed at the bottom of the support frame. The positions of each group of spotlights 2 and the triangular light receiving block 21 correspond to each other. There is a position difference in the installation positions of the spotlights 2 corresponding to the same row of cargo placement areas, and there is also a position difference in the installation positions of the triangular light receiving blocks 21 corresponding to the same row of cargo placement areas. The spotlights 2 and the triangular light receiving blocks 21 located in the front will not block the spotlights 2 and the triangular light receiving blocks 21 located in the rear. The installation density during specific use is set according to the shape and size of the cargo. When working, the spotlights 2 emit light upwards. When cargo is placed above the spotlights 2, the light emitted by the spotlights 2 is blocked. When no cargo is placed on the spotlights 2, the light emitted by the spotlights 2 is blocked. A light spot is formed on the angled light receiving block 21, and the collection camera 3 is driven by the transverse driving trolley 4 to move transversely on the supporting track plate 6 to collect images of the light spots reflected by the triangular light receiving block 21. The number of light spots can be counted in the background to count the number of goods arranged vertically on the shelf. When the rear goods are blocked by the goods placed in the front, it will not affect the counting of the number of goods by the device. The limit connecting rod 5 and the supporting track plate 6 can cooperate to limit the collection camera 3 and the transverse driving trolley 4 to maintain the stability of the transverse movement of the transverse driving trolley 4. After the counting of the goods in the same horizontal row is completed, the transverse driving trolley 4 drives the collection camera 3 to move to the top of the horizontal position adjustment plate 7, and the driving mechanism 8 drives the horizontal position adjustment plate 7 to move up and down to count the goods in another horizontal row.
[0019] A strip-shaped clearance groove 11 is provided on the side wall of the storage shelf 1, and a limit ring 41 is fixedly connected to the top end of the transverse driving trolley 4; the strip-shaped clearance groove 11 can play a clearance role, so that the horizontal position adjustment plate 7 can be connected to the driving mechanism 8, and the limit ring 41 can be provided to limit the horizontal position adjustment plate 7 when the transverse driving trolley 4 moves to the top end of the horizontal position adjustment plate 7.
[0020] The bottom end of the limit connecting rod 5 is fixedly connected to the limit slider 51, the limit slider 51 is fixedly connected to the acquisition camera 3, the bottom end of the support track plate 6 is fixedly connected to the limit slide rail 61, and the limit slider 51 is slidably connected to the outer wall of the limit slide rail 61; by setting the limit slider 51, it can cooperate with the limit slide rail 61 to play a limiting role, so as to limit and guide the acquisition camera 3 and the transverse driving trolley 4, so that the transverse driving trolley 4 can stably move transversely on the support track plate 6 along the transverse direction of the support track plate 6, avoiding the transverse driving trolley 4 from losing contact with the support track plate 6, and when the transverse driving trolley 4 moves at the top of the support track plate 6, the limit slider 51 slides on the outer wall of the limit slide rail 61.
[0021] The bottom end of the horizontal position adjustment plate 7 is fixedly connected to a limit block 71, and the limit block 71 corresponds to the size of the limit slide rail 61. The top of the horizontal position adjustment plate 7 is fixedly connected to a plug rod 72, and the plug rod 72 is detachably connected to the limit ring 41; when the transverse driving trolley 4 moves transversely to the top end of the horizontal position adjustment plate 7, the limit sliding block 51 is sleeved on the outside of the limit block 71, and the plug rod 72 is plugged into the limit ring 41. By setting the limit block 71 and the plug rod 72, the transverse driving trolley 4 can be limited when the transverse driving trolley 4 moves to the top end of the horizontal position adjustment plate 7, so as to avoid the transverse driving trolley 4 from losing contact with the horizontal position adjustment plate 7 when the horizontal position adjustment plate 7 drives the transverse driving trolley 4 to move upward.
[0022] A driving mechanism 8 is slidably connected to one side of the horizontal position adjustment plate 7, and the driving mechanism 8 is located in the storage shelf 1; by setting the driving mechanism 8, the horizontal position adjustment plate 7 can be driven to move. The driving mechanism 8 is composed of a screw and a sleeve. The screw rotates under the action of the driving motor, and the horizontal position adjustment plate 7 and the sleeve are limited by the strip-shaped clearance groove 11. The sleeve slides on the screw to achieve the up and down adjustment of the horizontal position adjustment plate 7.
[0023] The working principle and use process of the utility model are as follows: when working, the spotlight 2 emits light upwards. When goods are placed above the spotlight 2, the light emitted by the spotlight 2 is blocked. When no goods are placed on the spotlight 2, the light emitted by the spotlight 2 forms a light spot on the triangular light receiving block 21. The collection camera 3 is driven to move horizontally on the supporting track plate 6 to collect images of the light spots reflected by the triangular light receiving block 21. The number of light spots can be counted in the background to count the number of goods arranged vertically on the shelf. After the inventory of the horizontal row of goods is completed, the transverse driving trolley 4 drives the collection camera 3 to move horizontally on the supporting track plate 6 until the transverse driving trolley 4 moves to the top of the horizontal position adjustment plate 7, and the screw rod rotates under the action of the driving motor to drive the sleeve to move on the screw rod to adjust the horizontal position of the horizontal position adjustment plate 7, and adjust the horizontal position adjustment plate 7 to the corresponding position of another supporting track plate 6. The transverse driving trolley 4 moves from the horizontal position adjustment plate 7 to the supporting track plate 6 again to count the goods in another horizontal row.
