Description

Technical Field

[0001] This invention belongs to the technical field of tool storage and retrieval control cabinets, specifically an intelligent tool storage and retrieval control cabinet and storage and retrieval method. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. Most cutting tools are machine-made, but some are hand-made. Common cutting tool materials include carbon steel, stainless steel, high-speed steel, ceramics, and synthetic materials.

[0003] Intelligent tool storage and retrieval control cabinet is a tool storage device that integrates intelligent management. Compared with traditional tool cabinets, it can not only store tools, but more importantly, it has the ability to intelligently identify, track and manage tools. This type of cabinet is usually equipped with high-tech components such as electronic tags, sensors, and controllers. Through these sophisticated electronic devices, it can achieve real-time tracking and management of tool information.

[0004] A search revealed a Chinese patent, CN217620509U, for a machining tool storage cabinet. This cabinet comprises an outer shell, a fixed base, a partition, a scrap cabinet, an image recognition camera, an embedded image recognition camera, a tool tray, tools, a touch-screen all-in-one machine, a tool cabinet door, and a door lock. The beneficial effects of this machining tool storage cabinet are that it utilizes an intelligent IoT control system and graphic image recognition technology to create an efficient and convenient tool management mode, reducing labor and material costs. Users can access tools by scanning a code, using facial recognition, or an RFID card. The data on the accessed tools is uploaded to a cloud server for administrators to view, allowing for a deeper understanding of processing costs and efficient, convenient tool management.

[0005] Intelligent tool storage and retrieval control cabinets play an important role in modern manufacturing, making tool management more convenient. However, current intelligent tool storage and retrieval control cabinets are generally equipped with several partitions to facilitate the management of multiple tools, which makes it particularly inconvenient for workers to retrieve tools from above, especially for workers who are not tall enough. This not only affects work efficiency but also increases the labor intensity of workers. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent tool storage and retrieval control cabinet and storage and retrieval method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent tool storage and retrieval control cabinet, including a storage and retrieval cabinet body, a cabinet door hinged to one side of the storage and retrieval cabinet body, tool trays evenly arranged inside the cabinet door, the cabinet door and the tool trays being slidably connected by a moving component, and a fixing component being arranged inside the tool trays;

[0008] The movable component includes connecting shafts fixedly installed on both sides of the tool tray. Both connecting shafts are embedded inside the first slide grooves. The two first slide grooves are respectively opened on both sides of the inner wall of the storage cabinet. A movable plate is slidably installed on the outer wall of one of the connecting shafts. An electric push rod is connected to one side of the movable plate. A rotating component is provided at one end of one of the connecting shafts.

[0009] When a tool needs to be retrieved, the cabinet door is first opened. Then, the electric push rod is activated via PLC control. The activation of the electric push rod moves the moving plate, which in turn moves the connecting shaft. The movement of the connecting shaft then moves the tool tray, causing the tool tray to slide outwards for easy access to the tool. This avoids the inconvenience caused by multiple partitions in current intelligent tool storage and retrieval control cabinets, which are typically designed for managing multiple tools. This is especially true for shorter workers, as it not only affects work efficiency but also increases their workload. This system improves the convenience and efficiency of tool storage and retrieval.

[0010] As a further technical solution of the present invention, the first groove is inclined downward.

[0011] The tool tray slides downwards as it moves outwards, reducing the distance between the upper tool tray and the operator, thus further improving the convenience of storing and retrieving tools.

[0012] As a further technical solution of the present invention, the rotating assembly includes a mounting base installed at one end of the connecting shaft, a second rotating shaft is provided inside the mounting base, one end of the second rotating shaft is fixedly connected to the connecting shaft, a worm gear is fixedly installed on the outer wall of the second rotating shaft, a worm is meshed with the top end of the worm gear, and a motor is installed at one end of the worm.

[0013] When the tool needs to be removed, the motor can be started by controlling the PLC. The start of the motor drives the worm to rotate, the rotation of the worm to rotate the worm wheel, the rotation of the worm wheel to rotate the second rotating shaft, the rotation of the second rotating shaft to rotate the connecting shaft, and the rotation of the connecting shaft to rotate the tool tray, causing the tool tray to tilt downwards, which facilitates the storage and retrieval of the tool and further improves the convenience and work efficiency of storing and retrieving the tool.

[0014] As a further technical solution of the present invention, the fixing component includes a partition fixedly installed inside the tool tray. The partitions are evenly arranged, and a connecting plate is slidably connected inside each partition. A first spring is provided on one side of the connecting plate, and a fixing plate is fixedly connected to the other side of the connecting plate.

[0015] When placing the knife, it is placed between two fixed plates and secured by the elastic force of the first spring, thereby improving the stability of the device.

[0016] As a further technical solution of the present invention, a third sliding groove is provided inside the tool tray, a first rotating shaft is installed inside the third sliding groove, a pressure plate is fixedly connected to the outer wall of the first rotating shaft, and a second spring is provided at the top of the pressure plate.

[0017] When storing blades with wide blades, the blades can be placed on their side so that the blades are in contact with the blade tray. Then, the pressure plate is rotated. When the pressure plate and the third slide are on the same vertical line, the pressure plate is pushed downward by the elastic force of the second spring, so that the pressure plate presses the blades together and fixes them, thus improving the adaptability of the device.

[0018] As a further technical solution of the present invention, the first rotating shaft is movably connected to the third sliding groove.

[0019] As a further technical solution of the present invention, the tool tray has a second sliding groove inside, and the first sliding groove and the second sliding groove are slidably connected.

[0020] As a further technical solution of the present invention, a cleaning plate is embedded inside the partition.

[0021] When storing knives, you can first insert the blade into the cleaning plate and move it around to clean it. This prevents stains and residues on the knife surface from reacting chemically with the metal surface of the knife, which could cause rust or corrosion. Cleaning the blade can protect the surface of the knife from damage, extend the life of the knife, and thus improve the storage effect.

[0022] As a further technical solution of the present invention, a first magnetic block is fixedly connected to both sides of the cleaning plate, and a second magnetic block is provided on the side of the first magnetic block away from the cleaning plate, and the second magnetic block is fixedly installed inside the partition.

[0023] When the cleaning plate needs to be replaced, simply remove the cleaning plate to separate the first and second magnetic blocks, making it easier to replace the cleaning plate.

[0024] A method for storing and retrieving tools in an intelligent tool storage and retrieval control cabinet includes the following steps:

[0025] S1: When storing tools, first open the cabinet door, then start the electric push rod and motor through PLC control. The start of the electric push rod drives the movement of the moving plate, the movement of the moving plate drives the movement of the connecting shaft, and the movement of the connecting shaft drives the movement of the tool tray, causing the tool tray to slide outward.

[0026] S2: The starting of the motor drives the worm to rotate, the rotation of the worm drives the rotation of the worm wheel, the rotation of the worm wheel drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the connecting shaft, and the rotation of the connecting shaft drives the rotation of the tool tray, causing the tool tray to tilt downward.

[0027] S3: Select a suitable tool tray according to the type of tool. When placing the tool, first insert the blade into the cleaning plate and move it to clean it. Then place the tool in the tool tray and place the handle between the two fixing plates. The two fixing plates clamp the handle of the tool and fix it by the elastic force of the first spring. If the blade is wide, the pressure plate can be rotated to move the pressure plate out from the second slide groove. When the pressure plate and the third slide groove are on the same vertical line, the pressure plate is pushed downward by the elastic force of the second spring to press the blade and fix it.

[0028] S4: After placement, similarly, the tool tray is moved back to its original position by the electric push rod and motor start-up for storage.

[0029] The beneficial effects of this invention are as follows:

[0030] This invention, through the design of a moving component, first opens the cabinet door when a tool needs to be retrieved. Then, a PLC-controlled electric push rod is activated, which moves a moving plate. The movement of the moving plate moves a connecting shaft, which in turn moves a tool tray, causing the tool tray to slide outwards for easy tool storage and retrieval. This avoids the problem of current intelligent tool storage and retrieval control cabinets typically having several partitions for managing multiple tools, making it particularly inconvenient for workers to retrieve tools from above, especially for shorter workers. This not only affects work efficiency but also increases the workload of workers, thus improving the convenience and efficiency of tool storage and retrieval.

[0031] This invention, through the setting of the rotating component, allows the PLC to control the motor to start when the tool needs to be removed. The start of the motor drives the worm gear to rotate, the rotation of the worm gear drives the rotation of the worm wheel, the rotation of the worm wheel drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the connecting shaft, and the rotation of the connecting shaft drives the rotation of the tool tray, causing the tool tray to tilt downwards, facilitating the storage and retrieval of the tool, and further improving the convenience and work efficiency of storing and retrieving the tool.

[0032] This invention, through the setting of a cleaning plate, allows the blade of a knife to be embedded in the cleaning plate and moved for cleaning when placed. This prevents stains and residues on the knife surface from chemically reacting with the metal surface of the knife, which could lead to rust or corrosion. Cleaning the knife surface can protect the knife surface from damage, extend the service life of the knife, and thus improve the storage effect. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1 to 4As shown in the embodiment of the present invention, an intelligent tool storage and retrieval control cabinet includes a storage cabinet 1, a cabinet door 2 hinged to one side of the storage cabinet 1, tool trays 3 evenly arranged inside the cabinet door 2, the cabinet door 2 and the tool trays 3 being slidably connected by a moving component, and a fixing component being arranged inside the tool trays 3.

[0045] The movable component includes connecting shafts 4 fixedly installed on both sides of the tool tray 3. Both connecting shafts 4 are embedded inside the first slide groove 21. The two first slide grooves 21 are respectively opened on both sides of the inner wall of the storage cabinet 1. A movable plate 19 is slidably installed on the outer wall of one of the connecting shafts 4. An electric push rod 20 is connected to one side of the movable plate 19. A rotating component is provided at one end of one of the connecting shafts 4.

[0046] The existing patent CN217620509U discloses a machining tool storage cabinet. This patent discloses the storage cabinet body 1, cabinet door 2 and tool tray 3 proposed in this application. The technical means will not be described in detail here.

[0047] By setting up the moving components, when a tool needs to be retrieved, the cabinet door 2 is first opened, and then the electric push rod 20 is started by the PLC control. The start of the electric push rod 20 drives the moving plate 19 to move, the moving plate 19 drives the moving shaft 4 to move, and the moving shaft 4 drives the moving tool tray 3 to move, so that the tool tray 3 slides outward, making it easier to store and retrieve tools. This avoids the current intelligent tool storage and retrieval control cabinet, which is generally equipped with several partitions 6 for easy management of multiple tools, making it particularly inconvenient for staff to retrieve tools from above, especially for staff who are not tall enough. This not only affects work efficiency but also increases the labor intensity of staff. This improves the convenience and efficiency of tool storage and retrieval.

[0048] like Figures 1 to 4 As shown, the first slide 21 is inclined downwards.

[0049] When the tool tray 3 moves outward, it slides downward, reducing the distance between the upper tool tray 3 and the operator, further improving the convenience of storing and retrieving tools.

[0050] like Figures 1 to 4 As shown, the rotating assembly includes a mounting base 5 installed at one end of the connecting shaft 4. A second rotating shaft 15 is provided inside the mounting base 5. One end of the second rotating shaft 15 is fixedly connected to the connecting shaft 4. A worm gear 16 is fixedly installed on the outer wall of the second rotating shaft 15. A worm 17 is meshed with the top end of the worm gear 16. A motor 18 is installed at one end of the worm 17.

[0051] The bottommost tool tray 3 is slidably connected to the storage cabinet 1 via the connecting shaft 4. It can be slid out directly without rotation to access the tools inside.

[0052] By configuring the rotating assembly, when the tool needs to be removed, the motor 18 can be started via PLC control. The start of the motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 16 to rotate. The rotation of the worm wheel 16 drives the second rotating shaft 15 to rotate, which in turn drives the connecting shaft 4 to rotate. The rotation of the connecting shaft 4 drives the tool tray 3 to rotate, causing the tool tray 3 to tilt downwards, facilitating the storage and retrieval of tools and further improving the convenience and efficiency of tool storage and retrieval.

[0053] like Figures 1 to 4 As shown, the fixing component includes a partition 6 fixedly installed inside the tool tray 3. The partitions 6 are evenly arranged, and a connecting plate 24 is slidably connected inside each partition 6. A first spring 8 is provided on one side of the connecting plate 24, and a fixing plate 7 is fixedly connected to the other side of the connecting plate 24.

[0054] By setting up the fixing components, when placing the tool, the tool is placed between the two fixing plates 7 and fixed by the elastic force of the first spring 8, thereby improving the stability of the device.

[0055] Example 2

[0056] like Figures 5 to 8 As shown in the first embodiment, another embodiment of the present invention is as follows: a third slide groove 23 is provided inside the tool tray 3, a first rotating shaft 13 is installed inside the third slide groove 23, a pressure plate 12 is fixedly connected to the outer wall of the first rotating shaft 13, and a second spring 14 is provided at the top of the pressure plate 12.

[0057] When storing blades with a wide blade surface, the blade can be placed on its side so that the blade surface is in contact with the blade tray 3. Then, rotate the pressure plate 12. When the pressure plate 12 and the third slide groove 23 are on the same vertical line, the pressure plate 12 is pushed downward by the elastic force of the second spring 14, so that the pressure plate 12 presses the blade surface to fix it, thereby improving the adaptability of the device.

[0058] like Figure 5 , Figure 6 and Figure 7 As shown, the first rotating shaft 13 is movably connected to the third sliding groove 23.

[0059] like Figure 5 and Figure 6 As shown, the tool tray 3 has a second groove 22 inside, and the first groove 21 is slidably connected to the second groove 22.

[0060] The pressure plate 12 can be embedded in the second groove 22 to store the pressure plate 12.

[0061] like Figures 1 to 6 As shown, a cleaning plate 9 is embedded inside the partition 6.

[0062] When storing knives, you can first insert the blade into the cleaning plate 9 and move it to clean it. This prevents stains and residues on the knife surface from reacting chemically with the metal surface of the knife, which could cause rust or corrosion. Cleaning the blade can protect the surface of the knife from damage, extend the service life of the knife, and thus improve the storage effect.

[0063] like Figure 6 and Figure 8 As shown, a first magnetic block 10 is fixedly connected to both sides of the cleaning plate 9. A second magnetic block 11 is provided on the side of the first magnetic block 10 away from the cleaning plate 9. The second magnetic block 11 is fixedly installed inside the partition plate 6.

[0064] When it is necessary to replace the cleaning plate 9, the cleaning plate 9 can be removed directly to separate the first magnetic block 10 and the second magnetic block 11, making it easier to replace the cleaning plate 9.

[0065] A method for storing and retrieving tools in an intelligent tool storage and retrieval control cabinet includes the following steps:

[0066] S1: When storing the tools, first open the cabinet door 2, and then start the electric push rod 20 and motor 18 through the PLC control. The start of the electric push rod 20 drives the movement of the moving plate 19, the movement of the moving plate 19 drives the movement of the connecting shaft 4, and the movement of the connecting shaft 4 drives the movement of the tool tray 3, so that the tool tray 3 slides outward.

[0067] S2: The start of motor 18 drives the rotation of worm 17, the rotation of worm 17 drives the rotation of worm wheel 16, the rotation of worm wheel 16 drives the rotation of second rotating shaft 15, the rotation of second rotating shaft 15 drives the rotation of connecting shaft 4, and the rotation of connecting shaft 4 drives the rotation of tool tray 3, causing tool tray 3 to tilt downward.

[0068] S3: Select a suitable tool tray 3 according to the type of tool. When placing the tool, first insert the blade into the cleaning plate 9 and move it to clean it. Then place the tool in the tool tray 3 and place the handle between the two fixing plates 7. The two fixing plates 7 clamp the handle of the tool and fix it by the elastic force of the first spring 8. If the blade is wide, the pressure plate 12 can be rotated out of the second slide groove 22. When the pressure plate 12 and the third slide groove 23 are on the same vertical line, the pressure plate 12 is pushed downward by the elastic force of the second spring 14 to press the blade and fix it.

[0069] S4: After placement, similarly, the electric push rod 20 and motor 18 are activated to move the tool tray 3 back to its original position for storage.

[0070] Working principle and usage process:

[0071] When storing the knives, first open the cabinet door 2, and then start the electric push rod 20 and motor 18 through the PLC control. The start of the electric push rod 20 drives the movement of the moving plate 19, the movement of the moving plate 19 drives the movement of the connecting shaft 4, and the movement of the connecting shaft 4 drives the movement of the knife tray 3, causing the knife tray 3 to slide outward.

[0072] The starting of motor 18 drives the rotation of worm 17, the rotation of worm 17 drives the rotation of worm wheel 16, the rotation of worm wheel 16 drives the rotation of second rotating shaft 15, the rotation of second rotating shaft 15 drives the rotation of connecting shaft 4, and the rotation of connecting shaft 4 drives the rotation of tool tray 3, causing tool tray 3 to tilt downward.

[0073] Then the handle of the tool is placed between the two fixing plates 7, and the two fixing plates 7 clamp the handle of the tool and fix it by the elastic force of the first spring 8.

[0074] When placing knives, staff can first insert the blade into the cleaning plate 9 and move it to clean it, and then place the knife in the knife tray 3.

[0075] Before placement, a suitable tool tray 3 can be selected according to the type of tool. If the tool surface is wide, the pressure plate 12 can be rotated out of the second slide groove 22. When the pressure plate 12 and the third slide groove 23 are on the same vertical line, the pressure plate 12 is pushed downward by the elastic force of the second spring 14 to press the tool surface and fix it.

[0076] After placement, similarly, the electric push rod 20 and motor 18 are activated to move the tool tray 3 back to its original position for storage.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
