Description

Technical Field

[0001] The present invention relates to the technical field of circuit board storage appliances, and particularly relates to a storage bin structure with automatic feeding. Background Art

[0002] The mobile phone circuit board is an important part of the internal circuit of the mobile phone. It is a substrate that fixes and combines wires, electronic components, and Internet circuits; the PCB board is manufactured by an electro-chemical method and can provide reliable electrical connections and stable electrical performance. In a mobile phone, it plays an important role in realizing the connection and intercommunication between various electronic components. The material selection of the PCB board directly affects the performance and reliability of the mobile phone; before processing the mobile phone circuit board, generally, the circuit boards are stacked and stored in a storage bin.

[0003] Since the existing storage bins are generally box structures with an upward opening, although this type of storage bin can also store mobile phone circuit boards, when welding the electronic components on the circuit board, it is still necessary to extend an external robotic arm into the box to take out the circuit board. Moreover, before feeding the circuit boards stacked inside this single-shell structure storage bin, automatic sorting and centering operations cannot be performed, resulting in the need for the external robotic arm to adjust the position of the circuit board after taking out the mobile phone circuit board before welding. And after taking out all the circuit boards in this box, it is also necessary to wait for a new storage bin to be placed at the position to be taken before continuing the feeding operation. This not only fails to achieve automatic feeding of the mobile phone circuit boards stacked inside the storage bin but also seriously affects the working efficiency of processing the mobile phone circuit boards. Therefore, a storage bin structure that can solve the above defects is now designed. Summary of the Invention

Through the positioning block, the connecting rod 15 can be in a longitudinally perpendicular state to the feeding seat 13 in the pushing state; an inclined abutting groove is opened on the outer end surface of the deflection seat 14; a limiting groove is arranged on the inner wall of the one-way deflection groove in cooperation with the abutting groove, and a torsion spring 17 is installed between the abutting groove and the limiting groove; one end of the torsion spring 17 extends into the interior of the abutting groove and the other end abuts in the limiting groove; under the action of the torsion spring 17, it can not only push the storage rack 3 unidirectionally, but also enable the pushing plate 16 to automatically center and sort the mobile phone circuit boards placed in the storage rack 3 front and back when deflecting towards the interior of the storage rack 3, which can improve the neatness of the mobile phone circuit boards during feeding.

[0037] In the present invention, fixing seats 18 are fixedly arranged at the four corners of the bottom and top surfaces of the lower part of the storage rack 3. A buffer spring 24 is vertically arranged in the notch at the top of the fixing seat 18, and the top end of the buffer spring 24 is fixedly connected with a horizontal buffer block 25. The top surface of the buffer block 25 abuts against the bottom surface of the supporting frame 5; a plurality of stabilizing rods 26 are vertically fixedly connected to the peripheral side of the bottom surface of the buffer block 25, and stabilizing holes are equidistantly arranged on the peripheral side of the top surface of the fixing seat 18 in cooperation with the stabilizing rods 26.

[0038] Working principle: In this embodiment, the present invention also proposes a use method of an automatic feeding type storage bin structure, including the following steps:

[0039] Step 1, first electrically connect the electric push rod 8 and the electric jack 11 to an external control device through wires respectively, and then place the storage racks 3 full of mobile phone circuit boards into the interior of the storage bin box 1, and make the sliding seats 4 at the bottom of each storage rack 3 slide and sit on the top of the guide rail 2. At this time, the bottom end of the limiting plate 21 will deflect and incline downward under the action of gravity, and the bottom end of the limiting plate 21 will abut against the vertical surface of the right-angled triangular clamping block 23, so as to make the storage rack 3 can only horizontally slide on the guide rail 2 towards the direction of the baffle 9 and will not move backward;

[0040] Step 2: Then, start the electric push rod 8 to drive the moving seat 7 to slide on the guiding seat 6. When the moving seat 7 moves towards the electric push rod 8, at this time, when the feeding mechanism following the moving seat 7 encounters one side frame of the storage rack 3, since the storage rack 3 cannot move back under the action of the one-way limiting component at this time, when the pushing plate 16 in the feeding mechanism abuts against the storage rack 3, the pushing plate 16 will drive the connecting rod 15 to retract and store towards the inside of the one-way deflection groove with the deflection seat 14 as the center under the resistance of the storage rack 3. Thus, the feeding mechanism at this time will not limit the backward movement of the moving seat 7, and the feeding mechanism is in a retracted state at this time. And under the action of the torsion spring 17, when the pushing plate 16 deflects towards the inside of the storage rack 3, it can automatically center and arrange the mobile phone circuit boards placed in the storage rack 3 front and back, which can improve the neatness of the mobile phone circuit boards during feeding;

[0041] Step 3: When the moving seat 7 drives the feeding mechanism to move to the other side of the storage rack 3, after the connecting rod 15 and the pushing plate 16 are no longer subjected to extrusion force at this time, the deflection seat 14 will be pushed by the resilience of the torsion spring 17 to drive the pushing plate 16 to rotate and unfold. Thus, the pushing plate 16 is located on the other side of the storage rack 3. Then, start the electric push rod 8 to drive the moving seat 7 to move towards the baffle 9, so that the pushing plate 16 abuts against the other side surface of the storage rack 3. And at this time, the connecting rod 15 is in a state longitudinally perpendicular to the feeding seat 13 under the limiting action of the closed end of the one-way deflection groove. Then, through the moving moving seat 7 and the feeding seat 13, the storage rack 3 is pushed to slide horizontally towards the baffle 9 by the pushing plate 16 abutting against one side of the storage rack 3, and the one-way limiting component will not limit the storage rack 3 moving towards the baffle 9 at this time;

[0042] Step 4: With the cooperation of the electric push rod 8, the moving seat 7 and the feeding mechanism, when the storage rack 3 to be fed is pushed directly above the lifting plate 10, one end of the storage rack 3 will abut against the baffle 9 at this time, and under the action of the one-way limiting component, the storage rack 3 will not move after moving in place;

[0043] Step Five: Then start the electric jack 11 to raise the jacking plate 10. At this time, the damping block 19 on the jacking plate 10 will enter the storage rack 3 through the through-hole on the bottom frame of the storage rack 3, and the bottom surface of the damping block 19 will abut against the bottom surface of the supporting frame 5, improving the anti-offset effect of the supporting frame 5 during the jacking operation and enhancing the stability during jacking. Then, as the jacking plate 10 and the damping block 19 rise, the mobile phone circuit boards stacked on the top of the supporting frame 5 can be jacked up, so that the topmost mobile phone circuit board can rise out of the upper opening of the storage rack 3, facilitating the automatic manipulator to pick up the risen mobile phone circuit board, and improving the continuity and efficiency of feeding the mobile phone circuit boards.

[0044] 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.
