Enterprises often change production plans due to material shortages. Therefore, enterprises will store a large amount of materials required during the production cycle. In the production of an enterprise, the storage of materials is often the most complex, and it is often necessary to control the incoming and outgoing of materials. The existing material management methods mainly rely on scanning codes for storage. Manual operations have storage errors and are prone to misjudging the remaining amount of materials. Moreover, for the existing material picking and conveying equipment, when picking materials, it mainly picks by clamping method, and it cannot effectively pick heavier materials. And for the upward stacked storage of materials, it is necessary to ensure accurate positioning of the materials, otherwise it is extremely easy to occur the situation of the center of gravity of the materials tilting and toppling. Furthermore, it is impossible to obtain the data of the remaining materials in real time through Internet of Things interconnection technology, and it is impossible to control the remaining amount of materials. Based on this, a material control device based on Internet of Things technology is proposed. Summary of the Invention

Detailed implementation mode

[0026] 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.

[0027] Example, refer to Figures 1-6 , a material control device based on Internet of Things technology, including a material quality control platform 1, and a plurality of uniformly arranged storage seats 2 are provided on the material quality control platform 1. Further, a deep recess 13 for the lifting plate 7 to move is opened on the storage seat 2, and moving rollers 14 for reducing the friction with the material are provided on the storage seat 2.

[0028] Among them, the storage seat 2 and the storage protection rack 3 provided on the top form a shelf for storing materials. It should be noted that the distance between the storage protection racks 3 is not enough to take out the materials from above, that is, the materials can only be horizontally accessed from the bottom storage seat 2, so as to effectively support the materials through the storage protection rack 3.

[0029] Further, a cavity is opened inside the storage seat 2, a contact plate 15 is connected to the inner wall of the cavity through a contact spring, an L-shaped limiting angle block 16 extending outward through the side wall of the storage seat 2 is fixedly connected to the top of the contact plate 15, a control connection port communicating with the cavity is opened on one side of the contact plate 15, and a triangular contact strip 17 fixedly connected to the contact plate 15 is arranged in the control connection port;

[0030] It should be noted that the contact spring applies an upward pressure to the contact plate 15, so that the L-shaped limiting angle block 16 arranged above the contact plate 15 can effectively support the materials on the storage seat 2 in the storage state, effectively avoiding the sliding of the materials. Under the combined action of the storage protection rack 3, the materials can be effectively protected and limited, ensuring the safety of the materials in the storage state.

[0031] An electromagnetic repulsion seat 18 is provided at the end of the transfer conveyor platform 8, and the electromagnetic repulsion seat 18 is connected to a triangular magnet 19 through a spring return member. When the triangular magnet 19 moves outward, the triangular resistance bar 17 will be squeezed, so that the resistance plate 15 connected to it drives the L-shaped limit angle block 16 to move downward, thereby releasing the limit on the material.

[0032] The advantage of adopting the above structure is that when it is necessary to transfer materials, the electromagnet in the electromagnetic repulsion seat 18 arranged at the transfer conveyor platform 8 can be powered. Under the action of the magnetic force, the triangular magnet 19 arranged to repel the magnetic force will move outward, thereby squeezing the triangular interference bar 17, so that the interference plate 15 connected to it drives the L-shaped limit angle block 16 to move downward, thereby releasing the horizontal limit on the material.

[0033] Electric slide rails 4 for conveying materials are arranged on both sides of the storage seat 2, and a material lifting and conveying module and a material control and transfer module are arranged on the electric slide rails 4 on both sides of the storage seat 2 through two sets of sliding components;

[0034] Furthermore, the sliding assembly includes a self-driving slider 20 arranged on the electric slide rail 4, and a plurality of self-driving sliders 20 are provided, which are respectively fixed at the bottom of the material conveying platform 5 and the transfer conveying platform 8, wherein the mating connection between the electric slide rail 4 and the self-driving slider 20 is the prior art and will not be described in detail here.

[0035] The material lifting and conveying module and the material control and transfer module can cooperate to achieve the effect of storing and retrieving materials;

[0036] The material lifting and conveying module includes a material conveying platform 5, one side of which is provided with a lifting seat 6 through an electric horizontal slide rail 30, and the lifting seat 6 is connected to a lifting plate 7 through a screw-screwed stable lifting assembly;

[0037] It is worth noting that the lifting seat 6 does not require horizontal pressure. In the selection of the horizontal moving structure, it is set as an electric horizontal slide rail 30, which is controlled by numerical control to ensure its movement accuracy and to ensure that the material can be accurately taken out of the storage seat 2. The electric horizontal slide rail 30 is a prior art and will not be described in detail here.

[0038] Furthermore, the screw-stabilized lifting assembly includes a lifting opening opened on the lifting seat 6, a movable seat 21 is slidably provided on the inner wall of the lifting opening through a guide column, the movable seat 21 is fixedly connected to the lifting plate 7, a lifting motor 22 is provided on the lifting seat 6, a driving screw 23 is fixedly connected to the output end of the lifting motor 22, and the lifting plate 7 is threadedly connected to the driving screw 23 through a screw nut.

[0039] It should be noted that there is sliding contact between the guide column and the movable seat 21, which can achieve the effect of limiting the upward and downward movement of the movable seat 21.

[0040] The material control transfer module includes a transfer conveyor table 8. On one side of the transfer conveyor table 8, there is a pushing seat 9. The pushing seat 9 is provided with an electric push rod 10. The electric push rod 10 is a prior art and will not be described in detail here. The electric push rod 10 is connected to a bearing plate 11 through a sliding pushing member. Further, the sliding pushing member includes a U-shaped pushing frame 24 fixedly connected to the output end of the electric push rod 10. The U-shaped pushing frame 24 is connected to a pushing rod 26 through a sliding shaft 25. The pushing rod 26 is fixedly connected to the bearing plate 11.

[0041] It should be noted that a sleeve hole is formed on the pushing rod 26 and sleeved with the sliding shaft 25, which can realize the sliding between the two. In this way, when the weighing device is needed to weigh the material, the remaining material can be weighed, and then the data can be entered into the Internet of Things to ensure that the material can be effectively recorded each time it is stored or retrieved.

[0042] A weighing device is provided at the bottom of the bearing plate 11. At the end of the bearing plate 11, a pushing plate 12 for pushing the bottommost material is fixedly provided. The setting of the pushing plate 12 can achieve the effect of weighing the bottommost material in advance before the bearing plate 11 moves.

[0043] Further, the weighing device includes two weighing support plates 27 provided at the bottom of the bearing plate 11. The weighing support plates 27 are connected to the bearing plate 11 through pressure sensors 28. The pressure sensors 28 are connected to the Internet of Things through a wireless module. At the bottom of the pushing plate 12, there is an inclined entering block 29 adapted to the deep recess 13.

[0044] Among them, by setting the inclined entering block 29, when the pushing plate 12 retracts, the gravity can be transferred from one side of the weighing support plate 27 to the pushing plate 12 through the setting of the inclined entering block 29, so as to achieve the effect of suspending the weighing support plate 27. To ensure that when the weighing support plate 27 is stressed, the weight of the remaining material can be known immediately, and the effect of effectively recording the remaining plastic data on the Internet of Things can be achieved. When not under stress, the pressure sensor 28 will not record data.

[0045] When the present invention is in use, it is divided into two modes: storing materials and taking out materials. Both modes need to be realized through the cooperation of the material lifting and conveying module and the material control transfer module. The specific steps are as follows:

[0046] When storing materials, the materials are transferred to the transfer conveyor table 8. The material conveyor table 5 and the transfer conveyor table 8 move synchronously and move to both sides of the storage seat 2 for storing the materials. At this time, the lifting plate 7 on the material conveyor table 5 is matched with the deep groove 13 provided on the storage seat 2. Through the electric horizontal slide rail 30, the lifting plate 7 is horizontally moved into the deep groove 13. At this time, the lifting motor 22 in the lifting seat 6 is controlled to work to lift the materials upward to a height where one piece of material can be stored. At this time, through the movement of the pushing plate 12 on the transfer conveyor table 8, the materials are conveyed towards the storage seat 2. During the conveying process, the materials are stored at the bottom of the storage seat 2, thus realizing the storage of the materials.

[0047] When taking out materials, the material conveyor table 5 and the transfer conveyor table 8 are moved synchronously, and the carrier plate 11 provided on the transfer conveyor table 8 is driven to move horizontally. During the movement, the pushing plate 12 will push the material box at the bottommost position during the forward movement, and finally push the material box onto the material conveyor table 5. At this time, the lifting plate 7 on the material conveyor table 5 can choose whether to press and clamp the materials according to the state of the materials to ensure the stability of the material discharging movement process.

[0048] The gravity of the materials in the material box above the taken-out materials will press down on the carrier plate 11. When the pushing plate 12 moves outwards and moves out of the storage seat 2, the weighing support plate 27 provided at the bottom of the carrier plate 11 will support the carrier plate 11 and the materials above it. At this time, the pressure sensor 28 provided on the weighing support plate 27 will detect the pressure of the materials, realizing the automatic weighing of the remaining materials during each discharging process, recording the data and uploading it to the Internet of Things, which is convenient for the management of the materials in the warehouse and efficiently realizes the control of the materials.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
