DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] See attached Figures 1 to 12 As shown, a powder loading and storage workstation according to an embodiment of the present invention includes a frame and a closed space environment placed on the frame, wherein a powder loading system is arranged in the closed space environment, and the powder loading system includes a turntable 2 driven by a motor, a storage turntable 3 driven by the turntable for storing a material box filled with powder, a cache table 6 for caching a material box filled with powder, an opening and closing cover device for opening the end cover of the material box and covering the end cover on the material box after the sprinkling operation is completed, a recovery tray 15 for recovering empty material boxes, and a recovery tray robot 9 for transferring the material box on the storage turntable to the cache table, sending the material box to the opening and closing cover device for opening the cover, sending the opened material box to the outside of the closed space environment for sprinkling, and sending the empty material box to the opening and closing cover device for closing the cover after the sprinkling is completed, and sending the closed material box to the recovery tray robot 9.

[0032] In some embodiments, the rack has a lower space and an opening and closing door panel 24, and there is a corresponding space inside to place the installation mechanism or drive mechanism of the equipment. The bottom of the rack has support feet 26, which can support the equipment on the installation ground, and is equipped with liftable horizontal adjustment casters 25 for easy movement. The support feet are connected to the rack with bolts and can be fixed to the installation ground with bolts.

[0033] Specifically, the storage turntable is driven to rotate by a stepper motor 1 and has multiple hoppers or positioning mechanisms for storing cartridges. In a preferred embodiment, the storage turntable is provided with multiple positioning slots, arranged in at least one annular circle around the center of the turntable. The storage turntable is a circular disk. Preferably, the positioning slots conform to the shape of the cartridges and are used to position the cartridges. The depth of the positioning slots is less than the height of the cartridges. The cartridges are cylindrical, with a lid at the top that can be rotated open and closed, containing the corresponding powder.

[0034] In some embodiments, a detection switch 4 is provided on one side of the storage turntable for detecting whether there is a material box on the storage turntable 3. When it is detected that there is no material box, manual loading can be prompted.

[0035] In some embodiments, there is an information recognition module 5 on one side of the storage turntable 3 for reading the information on the material box and recording and storing it. This can be achieved by using a data processing mechanism or module with a scanning module to scan the information on the material box.

[0036] In some embodiments, an empty bin detection switch 7 is arranged on one side of the cache table 6, and a full bin detection switch 8 is arranged on the other side thereof, for detecting the occupancy status of the cache table. There are two empty bin detection switches 7 and two full bin detection switches 8, which are arranged separately at preset positions.

[0037] In some embodiments, the cover opening and closing device is installed on a support frame 12, and includes a servo electric clamp 14 for opening the end cover of the material box and a servo slide 13. The servo slide 13 drives the servo electric clamp 14 to move up and down, and the servo electric clamp 14 can clamp the end cover of the material box and rotate it, thereby realizing the operation of opening or closing the end cover.

[0038] In some embodiments, a micro torque electric cylinder 11 and a torque electric clamp 10 are installed at the front end of the robot. The torque electric clamp 10 is used to clamp the material box and perform preset actions under the drive of the robotic arm. The micro torque electric cylinder 10 is used to slightly collide with the surface of the material box during the sprinkling process to discharge the powder in the material box and prevent the powder from adhering to the inner wall of the material box and being unable to be discharged.

[0039] In some embodiments, the closed space environment is formed by connecting the upper frame of the rack and the box panels on the four sides. The overall outer frame box 19 is rectangular, and there is an opening and closing door panel 22 on the front. There is a loading door 21 on the front side of the closed space environment corresponding to the loading port 20 of the storage turntable, which is connected to the rack with a hinge.

[0040] In some embodiments, an automatically controlled sliding door 18 is provided on the rear side of the outer frame box 19. The sliding door 18 is used to open before the robot sprinkles the materials. The robot extends its robotic arm and clamps the opened material box to perform a rotating material sprinkling operation outside the enclosed space environment.

[0041] In some embodiments, the sliding door can be driven by a servo electric cylinder 17 or a servo motor to move left and right to open or close the window on the back of the outer frame box. Specifically, the servo electric cylinder / servo motor installed on the sliding door is connected to a drive gear 28, which is engaged with the matching rack 27 to control the opening or closing of the sliding door.

[0042] In some embodiments, a material box recovery door 23 is provided at the position of the recovery tray corresponding to the front side of the closed space environment, which is hingedly connected to the frame to facilitate staff to take out empty material boxes and reload them.

[0043] In some embodiments, the buffering station 6 has a buffering plate with a plurality of magazine positioning slots, which is mounted at a predetermined height by a bracket. The recovery tray is supported by a recovery tray bracket 16 at a predetermined height.

[0044] The working principle of the powder material loading and storage workstation according to the embodiment of the present invention is as follows:

[0045] First, open the loading door of the loading port at the front end of the outer frame box 19, manually place the material box on the storage turntable 3, and the stepper motor 1 drives the turntable 2 to rotate in steps. After the storage turntable 3 is filled in sequence, the loading port of the outer frame box 19 is closed to complete the loading work.

[0046] Inside the workstation, the detection switch 4 identifies the presence or absence of a material box. After confirmation, the information recognition module 5 reads the corresponding information storage. The robot 9, carrying the torque electric gripper 10, grabs the material box and places it on the cache table 6 to complete the cache processing operation of the material box. The empty warehouse detection switch 7 and the full warehouse detection switch 8 provide feedback on the occupancy status of the cache table 6. The empty warehouse detection switch 7 sends the replenishment information of the cache table when feedback, and the full warehouse detection switch 8 sends the information that the material box at the storage turntable 3 will not be grabbed for the time being.

[0047] The opening and closing device of the material box end cover is composed of the support frame, servo slide 13, and servo electric clamp 14. When production needs, the robot 9 carries the torque electric clamp 10 to grab the material box at the buffer table 6, and to the opening and closing position of the material box end cover, the servo electric clamp 14 grabs the material box end cover and rotates it. At the same time, the servo slide 13 carries the servo electric clamp 14 to move up to complete the opening of the material box end cover.

[0048] Afterwards, the servo electric cylinder 17 carries the sliding door 18 to open, and the robot 9 carries the torque electric gripper 10 to move the material box out and rotate and sprinkle it. At the same time, the micro torque electric cylinder 11 installed on the torque electric gripper 10 starts to work quickly and slightly collide with the material box to ensure that the powder in the material box is completely removed. After the operation is completed, the robot 9 moves the material box to the end cover opening and closing position, and the servo electric cylinder 17 carries the sliding door 18 to close; the servo slide 13 carries the servo electric gripper 14 to move down, and at the same time, the servo electric gripper 14 carries the material box end cover to rotate in the opposite direction to complete the closure of the material box end cover; after completion, the robot 9 places the empty material box on the recycling tray 15, waiting for manual labor to take away the empty material box and refill it.

[0049] The powder loading and storage workstation of the present invention abandons the previous form of pure manual operation or manual operation combined with semi-automatic equipment operation, and uses robots, torque electric grippers, micro torque electric cylinders, servo slides, servo electric grippers and other refined controllable components to achieve the functional requirements of handling, storing, and sprinkling of powdery items, ensuring the stability, controllability and accuracy of system operation. The closed operating environment avoids dust, leakage and other phenomena that are easily caused by the handling, storage, and sprinkling of powdery items.

[0050] When dealing with special environments such as hazardous substances, the powder loading and storage workstation of the present invention plays a role in regional isolation, reducing the contact between personnel and materials, and reducing the possibility of loss or omission of hazardous materials during personnel operation, thereby ensuring the personal health and safety of surrounding personnel; thereby providing a powder loading and storage workstation with stronger compatibility, higher precision, accurate repeatability, easy installation, easy replacement, small footprint and independent operating space.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0052] The embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being defined by the appended claims rather than the foregoing description, and all changes that come within the meaning and range of equivalents of the claims are therefore intended to be embraced therein.

[0053] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
