[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 creative efforts shall fall within the protection scope of the present invention. The following describes the specific implementation of the present invention in detail with specific embodiments.

[0024] A hole-position drawer includes a chassis 3, a box body 1 snap-fitted on the chassis 3, and a circuit board 2 installed at the bottom of the box body 1. The box body 1 is integrally formed by an injection molding process. A plurality of hole positions 13 are arranged in the box body 1, and indicator lights 21 for indicating the storage positions of items are provided on the circuit board 2 below the hole positions 13. The sizes and arrangement modes of the hole positions 13 can be determined according to factors such as the size of the drawer and usage requirements (such as the size of the stored object). This embodiment provides a drawer including 4 hole positions 13 with different aperture sizes, which can be used to store light-transmitting cylindrical items such as ampoules and vials with sizes between 10 mm and 22 mm, and the appropriate hole positions 13 can be selected according to the size of the items.

[0025] The chassis 3 includes a bottom frame 31 with an open top and a vertical plate 32 provided at the front end of the bottom frame 31. The box body 1 is snap-fitted on the bottom frame 31 without the need for fasteners, and the drawer is convenient to assemble.

[0026] The box body 1 includes a tabletop 11 and side walls 12. A plurality of hole positions 13 are arranged in the tabletop 11. A hole wall 15 with a certain height and perpendicular to the tabletop 11 is provided at the bottom of the tabletop 11 along the extension of the hole positions 13, so that the objects placed in the hole positions 13 remain stable during the drawer pulling process. There is a gap between the lower end of the hole wall 15 and the circuit board 2, and an opening is provided at the bottom of the hole wall 15. A chamfer is provided at the junction of the hole position 13 and the hole wall 15 to facilitate the storage of items. A thin-film pressure sensor 22 is provided on the circuit board 2 at the position corresponding to the hole position 13. When an item is placed in the hole position 13, the bottom of the item is placed on the thin-film pressure sensor 22, and the thin-film pressure sensor 22 detects the usage situation of the corresponding hole position 13.

[0027] A partition 14 is provided at the bottom of the tabletop 11. The partition 14 divides the box body 1 into multiple units. Each unit contains at least one hole 13. Each unit is a relatively independent chamber, and the same type of items can be stored in one unit. At least one indicator light 21 is provided in one unit. The indicator light 21 is an LED lamp bead. When the indicator light 21 is lit, the light emitted by the indicator light 21 can be observed through the hole 13 to indicate the position for taking and placing items. When taking out items, since the items placed in the hole 13 are glass ampoules, vials, etc., the emitted light makes the items glow, and the required items can be clearly observed and found. The partition 14 divides each unit, and the light emitted by the indicator light 21 can only be observed from the hole 13 belonging to this unit, preventing the indicator lights 21 between the holes 13 from transmitting light to each other and eliminating the interference of the indicator lights 21 on other holes 13. At the same time, the partition 14 also serves as a reinforcing rib of the drawer, significantly improving the structural strength of the drawer.

[0028] As a first embodiment of the partition 14, partitions 14 are provided between the holes 13, that is, one hole 13 is one unit. An indicator light 21 is provided on one side of the thin-film pressure sensor 22. When taking and placing items, the indicator light 21 of the hole 13 where the taking and placing position is located lights up to indicate the position for taking and placing items.

[0029] As a second embodiment of the partition 14, in a row of holes 13, multiple adjacent holes 13 are one unit. For example, three to five adjacent holes 13 are one unit. The indicator light 21 is provided between two adjacent holes 13. When storing items, the indicator lights 21 in this unit light up synchronously to indicate the position for taking and placing items, and the items can be taken out from any hole 13 in this unit or stored in any hole 13.

[0030] An optoelectronic sensor 23 is also provided on the circuit board 2. The optoelectronic sensor 23 is provided on both sides of the thin-film pressure sensor 22 to detect whether there are items placed in the holes 13. The optoelectronic sensor 23 is located at the gap between the lower end of the hole wall 15 and the circuit board 2. When an item is placed in the hole 13, the optoelectronic sensor 23 and the thin-film pressure sensor 22 jointly detect the placement situation of the item, judge which positions have items placed and the taking and placing positions of the items. The double-detection structure significantly improves the reliability of detection.

[0031] Multiple fixing columns 17 are provided in the partition 14, and bolt holes are provided in the circuit board 2. The circuit board 2 is fixedly installed at the bottom of the partition 14 by bolts. The circuit board 2 is an array-type switch quantity circuit board 2. A total of four circuit boards 2 are provided at the bottom of the partition 14 and are installed at the bottom of the drawer.

[0032] A card slot 16 is provided on the outer side of the side wall 12 at the front end of the box body 1. A slot hole 33 is provided at a position corresponding to the card slot 16 in the vertical plate 32. The positioning lamp 4 is snapped into the card slot 16 and is electrically connected to the circuit board 2. When storing or retrieving items, the positioning lamp 4 lights up to locate the position of the drawer and warns the user to avoid before the drawer of the automatic switch operates.

[0033] The circuit board 2 is communicatively connected to the controller. The controller is used to record information such as the type and storage time of items and control the storage position of items. When storing or retrieving items, the controller, according to the set program, determines the quantity of items to be stored or retrieved based on the type and inventory quantity of the items, and controls the indicator lamp 21 on the circuit board 2 at the storage or retrieval position to light up, realizing the traceable management of the whereabouts of items. The controller can control the order of item retrieval according to the storage time of the items, realizing the first-in, first-out management of items.

[0034] When storing items, the operator inputs the relevant information of the items to be stored into the controller. The controller, according to the set program, determines the storage position of the items based on the type and existing inventory of the items, determines the storage hole position 13, and the controller controls the indicator lamp 21 at the storage hole position 13 to light up. The pressure sensor and the photoelectric sensor 23 judge whether the storage position of the items is correct. When the photoelectric sensor 23 and the thin-film pressure sensor 22 detect that the placement position of the items is incorrect, the controller feeds back the information to the operator and prompts the operator to re-place the items in the correct position.

[0035] When retrieving items, the operator inputs the relevant information of the items to be retrieved into the controller. The controller, according to the set program, determines the retrieval position of the items based on the type, existing inventory and storage time of the items, and the controller controls the indicator lamp 21 at the storage hole position 13 to light up. The pressure sensor and the photoelectric sensor 23 judge whether the retrieval position of the items is correct. When the photoelectric sensor 23 and the thin-film pressure sensor 22 detect that the operator retrieves the items from the wrong position, the controller feeds back the information to the operator, prompts the operator to put back the mis-retrieved items, and retrieve the items to be retrieved again.

[0036] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
