[0049] The core of the present application is to disclose a fastener access bin to realize automatic access of the fastener to be accessed and improve work efficiency.

[0050] Another core of the present application is to disclose a charging system, which comprises the fastener access bin.

[0051] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not have any limiting effect on the invention content recited in the claims. In addition, the entire content of the configuration represented in the following embodiments is not limited to what is necessary as a solution to the invention recited in the claims.

[0052] During installation, use and maintenance of mechanical equipment, various screws are usually needed to be disassembled and assembled. The existing method is usually manual placement and taking, which affects work efficiency and is not suitable for some special fields. In view of this, the inventor of the present application discloses a fastener storage and taking bin to realize automatic storage and taking of fasteners.

[0053] In combination Figure 1 The fastener storage and taking bin disclosed by the embodiment of the present application comprises a mounting base 100, a storage bin disc 200 and a moving device. The storage bin disc 200 is arranged on the mounting base 100, and the storage bin disc 200 is provided with a storage bin chamber 211 which can store a fastener to be taken 600. The moving device is arranged on the mounting base 100, and the moving device is used to drive the fastener to be taken 600 to move between the storage bin chamber 211 and a taking starting position.

[0054] The fastener to be taken 600 located at the taking starting position can be moved by the moving device into the storage bin chamber 211 of the storage bin disc 200 for storage, and when the fastener to be taken 600 is needed to be used, the fastener to be taken 600 in the storage bin chamber 211 is moved by the moving device to the taking starting position, so as to facilitate the use of the fastener to be taken 600.

[0055] Compared with the prior art, the fastener storage and taking bin disclosed by the embodiment of the present application can realize automatic storage and taking of the fastener to be taken 600 during disassembly, assembly and maintenance, and can be applied to special working conditions which are not convenient for manual operation, so as to realize the storage and taking automation of the fastener to be taken 600 and improve the work efficiency.

[0056] Among them, the fastener to be taken 600 can be a screw, a bolt or the like.

[0057] In order to realize the storage of the fastener to be taken 600, the storage bin chamber 211 is a plurality of through hole positions formed in the storage bin disc 200, each storage bin disc 200 is used to store one fastener to be taken 600, and the fastener to be taken 600 is hung on the storage bin chamber 211.

[0058] In a specific embodiment disclosed by the present application, the moving device comprises a top rod mechanism 400 and a clamping mechanism 300. The top rod mechanism 400 is arranged on the lower side of the storage bin disc 200, the clamping mechanism 300 is arranged on the upper side of the storage bin disc 200, and the taking starting position is located on the clamping mechanism 300. The top rod mechanism 400 is used to push the fastener to be taken 600 to move between the storage bin chamber 211 and the taking starting position, and the clamping mechanism 300 is used to clamp the fastener to be taken 600.

[0059] The aperture of the storage chamber 211 is larger than the outer diameter of the ejector rod 420 and smaller than the diameter of the head of the fastener to be accessed 600, so that the ejector rod 420 can freely pass through the storage chamber 211, and the fastener to be accessed 600 can be hung in the storage chamber 211.

[0060] When the fastener to be accessed 600 needs to be taken out, the fastener to be accessed 600 hung in the storage chamber 211 can be pushed to the access starting position by the ejector rod mechanism 400 and clamped by the clamping mechanism 300.

[0061] When the fastener to be accessed 600 needs to be stored, the fastener to be accessed 600 clamped by the clamping mechanism 300 is pushed by the ejector rod mechanism, and then the clamping mechanism 300 is released. Finally, under the action of gravity, the fastener to be accessed 600 moves downward with the ejector rod mechanism and enters the storage chamber 211, realizing the storage of the fastener to be accessed 600.

[0062] On the fully automatic loading system, the fastener to be accessed 600 transported by other equipment (such as screws adsorbed on the transfer tooling) can be clamped and held at the access starting position by the clamping mechanism 300 for subsequent storage. When it needs to be taken out, the clamping of the fastener to be accessed 600 by the clamping mechanism 300 can facilitate the transfer of other equipment after the fastener to be accessed 600 is fixed (such as after the screw head is threaded into the tooling).

[0063] As shown in FIG. 1, Figure 1 The ejector rod mechanism 400 includes an ejector rod 420 and an ejector rod drive motor 410. The ejector rod 420 is arranged parallel to the extension direction of the storage chamber 211 and corresponds to the clamping mechanism 300 to push the fastener to be accessed 600 to move between the storage chamber 211 and the access starting position. The ejector rod drive motor 410 is arranged on the mounting base 100, and the ejector rod 420 is in transmission connection with the ejector rod drive motor 410 to drive the extension and retraction of the ejector rod 420 and push the fastener to be accessed 600.

[0064] In order to ensure the pushing effect of the ejector rod mechanism 400, the ejector rod 420 and the storage chamber 211 both extend in the vertical direction. It should be noted that the ejector rod 420 and the storage chamber 211 can be arranged at an angle with the vertical direction (i.e., inclined relative to the vertical direction), but this arrangement has the risk of the fastener to be accessed 600 falling. A magnetic attraction member can be arranged on the ejector rod 420 to facilitate attracting the fastener to be accessed 600 during transfer, further avoiding the fastener to be accessed 600 from falling.

[0065] To further ensure the pushing effect of the push rod mechanism and to prevent the fastener 600 to be stored from falling off during movement, a fastener tapered groove is provided at the end of the push rod 420 away from the push rod drive motor 410. The diameter of the rod body of the fastener 600 to be stored is smaller than the diameter of the large diameter end of the fastener tapered groove, but larger than the diameter of the small diameter end of the fastener tapered groove.

[0066] When the push rod 420 pushes the fastener 600 to be stored, the rod body of the fastener 600 is embedded in the fastener cone groove and fits against the side wall of the fastener cone groove to guide the fastener 600 to be stored and prevent tilting.

[0067] To ensure the accuracy of storing and retrieving the fasteners 600, the fastener storage compartment disclosed in this embodiment of the invention further includes a detection mechanism 500, such as... Figure 2 As shown, the detection mechanism 500 includes a photoelectric switch 520 and a proximity switch 510. The photoelectric switch 520 is mounted on the mounting base 100 and can detect the position of the fastener 600 to be stored, thereby determining whether the corresponding storage compartment 211 stores the fastener 600. The proximity switch 510 is mounted on the mounting base 100 and can detect the specific position of the moving end of the push rod 420. The detection mechanism 500 improves the accuracy of the storage and retrieval process.

[0068] The specific structures of photoelectric switch 520 and proximity switch 510 are existing technologies and will not be described in detail here.

[0069] The clamping mechanism 300 disclosed in this embodiment of the invention includes a clamping base 310, a clamping device 320, and a clamping drive motor 330. The clamping base 310 is disposed on a mounting base 100 and is used to mount the clamping device 320 and the clamping drive motor 330. The clamping device 320 is disposed on the clamping base 310 and is used to clamp the fastener 600 to be stored or retrieved. The clamping drive motor 330 is disposed on the clamping base 310 and is drively connected to the clamping device 320.

[0070] like Figure 4 As shown, the gripper 320 is provided with two grippers 321, which form a clamping groove for gripping the fastener 600 to be stored or retrieved. The gripping drive motor 330 can drive the two grippers to achieve opening and closing movements.

[0071] like Figure 1 As shown, a connecting platform 311 is provided on the mounting base 100, and a clamp fixing base 310 is disposed on the connecting platform 311, which is located in the middle of the mounting base 100. The clamp fixing base 310 and the connecting platform 311 are bolted together. The push rod drive motor 410 of the push rod mechanism 400 is bolted together with the connecting platform 311.

[0072] In a specific embodiment of the present invention, the moving device includes a clamping mechanism 300 and a lifting mechanism. The fixed end of the lifting mechanism is disposed on the mounting base 100, and the clamping mechanism 300 is disposed on the moving end of the lifting mechanism. The clamping mechanism 300 is used to clamp the fastener 600 to be stored or retrieved. The clamping mechanism 300 can be driven to rise or fall by the lifting mechanism, thereby moving the fastener 600 to be stored or retrieved between the storage compartment 211 and the storage / retrieval starting position. At this time, the storage compartment 211 can be a non-through hole, as long as a portion of the fastener 600 to be stored or retrieved is exposed for the clamping mechanism 300 to clamp.

[0073] The lifting mechanism includes a lifting drive motor and a lifting rod. The lifting drive motor is mounted on the connecting platform 311 and is connected to the lifting rod for transmission. The clamping mechanism 300 is located at the end of the lifting rod away from the lifting drive motor.

[0074] The storage tray 200 disclosed in this embodiment of the invention includes a rotating disk 210, a transmission rod 220, and a storage tray drive motor 230. The transmission rod 220 passes through the mounting base 100, and its first end is connected to the rotating disk 210. The rotating disk 210 has a plurality of storage compartments 211 arranged circumferentially along the transmission rod 220. The storage tray drive motor 230 is drivenly connected to the second end of the transmission rod 220 and is mounted on the mounting base 100 to drive the rotating disk 210 to rotate and to align each storage compartment 211 with a moving device.

[0075] Based on the specific position of the storage compartment 211 on the rotating disk 210, the required rotation angle of the rotating disk 210 each time can be calculated, and the rotation is directly controlled by the storage compartment drive motor 230, so that the photoelectric switch 520 can determine whether the corresponding storage compartment 211 contains the fastener 600 to be stored, and then the moving mechanism performs the corresponding action.

[0076] like Figure 1 As shown, the first end of the transmission rod 220 is a connecting plate, which is bolted to the rotating disk 210. The storage bin drive motor 230 and the mounting base 100 are bolted together.

[0077] Combination Figure 3 Storage compartment 211 consists of one or more concentric rings evenly distributed on storage tray 200. Figure 2 The diagram shows two rings, each ring containing multiple storage compartments 211, and each storage compartment 200 is equipped with a corresponding moving device to facilitate the movement of fasteners 600 located in different rings.

[0078] Furthermore, the storage compartment 211 can be designed in different sizes in conjunction with the fastener 600 to be stored and retrieved.

[0079] As shown in Figure 3 The storage chamber 211 is arranged in two circles of the storage chamber disc 200, the connecting platform 311 is arranged in one circle of the mounting base 100, the moving device is two, and is arranged at two ends of the connecting platform 311 respectively and corresponds to one circle of the storage chamber 211 respectively.

[0080] It can be understood by those skilled in the art that the moving device can further include a circumferential linear driving mechanism for driving the clamping mechanism 300 to move along the circumference of the rotating disc 210, so as to realize the movement of the moving device between different circle layers of the storage chamber 211, and only one moving device is arranged to access different circle layers of the fastener 600 to be accessed.

[0081] When the storage chamber disc 200 is fixed, the moving device can further include a circumferential circumferential driving mechanism for driving the clamping mechanism 300 to rotate around the circumference of the rotating disc 210, so as to realize the movement of the moving device to different fasteners 600 to be accessed in the same circle of the storage chamber 211, that is, only one of the storage chamber disc 200 and the moving device is selected to rotate to realize the relative rotation of the two.

[0082] The fastener 600 to be accessed can be a screw arranged on a high-temperature gas cooled reactor fuel storage container, so as to realize the automation of the high-temperature gas cooled reactor loading process by the fastener access warehouse disclosed in the embodiment of the application, improve the operation efficiency, and reduce the influence of the loading process on the body of the operator in the nuclear radiation operation condition.

[0083] In a specific embodiment disclosed in the application, the clamping mechanism 300 of the fastener access warehouse is in a closed state before storing the screw, the ejector rod 420 of the ejector rod mechanism 400 passes through a hole of the storage chamber 211 of the storage chamber disc 200 and rises to the top, when the screw is placed in the clamping mechanism 300 and the lower part of the screw contacts the ejector rod 420, the clamping mechanism 300 is released, the screw falls under the action of the ejector rod driving motor 410, and the screw falls into the corresponding hole of the storage chamber 211 of the rotating disc 210 under the guidance of the ejector rod 420, so as to realize the storage of the screw, the rotating disc 210 rotates to the next hole of the storage chamber 211, the ejector rod 420 passes through the next hole of the storage chamber 211 and rises to the top, and waits for the next screw.

[0084] The fastener access warehouse is in an open state before the screw is taken, the ejector rod 420 of the ejector rod mechanism 400 is below the screw to be taken, and is lowered to the bottom. When the screw needs to be taken, the ejector rod 420 is raised under the action of the ejector rod driving motor 410, and is raised together with the screw in the hole position of the corresponding storage chamber 211. After being raised to a certain height, the gripper 320 is closed, so that the screw is gripped by the gripper 320, and the next step of taking is waited. The ejector rod 420 is lowered to the bottom, the rotating disc 210 is rotated to the next screw position, and the screw in the next position is waited to be taken. In the screw taking process, whether the current storage chamber 211 hole position (the storage chamber 211 hole position opposite to the ejector rod 420) stores a bolt is detected by the photoelectric switch 520, and the position state of the ejector rod 420 is detected by the proximity switch 510.

[0085] The disclosed charging system of the embodiment of the application comprises the fastener access warehouse described above. Since the fastener access warehouse described above is used, the advantages described above are also achieved, and details are not repeated here.

[0086] The terms "first" and "second" and the like in the specification and claims of the application and the above drawings are used to distinguish different objects, and are not used to describe a specific sequence. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can include steps or units not listed.

[0087] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application.
