Example 3
Referring to fig. 1-7, this embodiment is a further improvement of embodiment 2, and it should be noted that, after the circuit board 2 on the top of the loading box 1 is removed, the abutting block 20 no longer restricts the rotation of the conveyor belt 4, at this time, the conveyor belt 4 will rapidly rotate around the conveying carrier 6 under the action of the spring 22, at this time, the circuit board 2 in the loading box 1 will be conveyed to the top opening of the loading box 1, and at this position, because the circuit board 2 is not removed yet, the first loading plate 11 holding the circuit board 2 is always under the abutting block 20, the abutting plate 21 mounted on the first loading plate 11 will abut against the abutting block 20, if the conveying speed of the conveyor belt 4 is too fast, the impact strength between the abutting block 20 and the abutting plate 21 will be increased, and the circuit board 2 may be separated from the loading box 1 under this impact strength, in order to promote the solution of the above problem, a damping device is further fixedly mounted on the second rotating shaft 9 for slowing down the rotating speed of the second rotating shaft 9.
Damping device includes buffer board 23 of fixed mounting on second pivot 9, has seted up dashpot 27 in the buffer board 23, and slidable mounting has damping piece 25 in dashpot 27, and one side of damping piece 25 is connected with the inner wall of dashpot 27 through buffer spring 24.
When conveyer belt 4 moves at the excessive speed, second pivot 9 rotates and drives buffer board 23 and rotates around second pivot 9, can produce centrifugal force when second pivot 9 rotates, make damping piece 25 to the direction motion of keeping away from second pivot 9, and then, damping piece 25 conflicts the inner wall of headstock 5, make the rotation of second pivot 9 can be obstructed, reduce the slew velocity of second pivot 9, thereby reach the velocity of movement when slowing down conveyer belt 4 conveying circuit board 2, avoid because speed is too big, and lead to circuit board 2 to break away from the condition of loading case 1, improve the device's practicality.
Further, the damping block 25 is further provided with a rubber block 26 for improving the friction force between the damping block 25 and the power box 5 when the damping block is in contact with the inside of the power box 5, and a ball 18 is further arranged between the damping block 25 and the inner wall of the buffer groove 27 for reducing the friction force between the damping block 25 and the buffer groove 27.
Further, the buffer plate 23 is tangent to the circumferential surface of the second rotating shaft 9.
When the second rotating shaft 9 rotates, the damping block 25 in the buffer plate 23 can be enabled to be better separated from the buffer groove 27, so that the damping block 25 is in contact with the power box 5, the second rotating shaft 9 is prevented from rotating, and the damping effect of the damping device is improved.
Further, because conveyer belt 4 itself possesses elasticity, if not set up the limit to conveyer belt 4 itself, conveyer belt 4 may take place when rotating that some positions on conveyer belt 4 will paste tight conveying carrier 6, thereby take place the friction of conveyer belt 4 between conveying carrier 6, and simultaneously, some positions on conveyer belt 4 also may take place and will keep away from conveying carrier 6, if this position takes place near conflict piece 20, it can't form the phenomenon of contradicting to conflict board 21 to take place to conflict piece 20 easily, spacing groove 10 has still been seted up in loading box 1, spacing groove 10 encircles conveying carrier 6 and sets up, still install slide bar 17 on the conveyer belt 4, the one end that the conveyer belt 4 was kept away from to slide bar 17 extends to in the spacing groove 10.

Example 4
Referring to fig. 1 to 7, this embodiment is a further improvement of embodiment 3, and it should be specifically described that when the limiting plate 14 is clamped between the second bearing plates 13, the second bearing plates 13 can play a role in clamping, but when the loading box 1 is transported and subjected to a large shock, the circuit board 2 is still easily separated from the clamping of the second carrier, for this reason, the scheme further includes a plurality of through grooves 16 formed on the conveyor belt 4, the through grooves 16 are slidably connected with the limiting plates 14, the limiting plates 14 are connected with the conveyor belt 4 through limiting springs 15, and the number of the limiting plates 14 corresponds to that of the first bearing plates 11 one by one;
one end of the limiting plate 14 penetrates through the through groove 16 and abuts against the conveying carrier 6, and the other end of the limiting plate 14 and the first bearing plate 11 form a clamping space for placing the circuit board 2, so that the circuit board 2 is promoted to be stably placed in the loading box 1;
the transport carrier 6 is further provided with a groove 19, and the groove 19 is used for accommodating the limit plate 14.
When circuit board 2 is placed in loading case 1, limiting plate 14 forms the centre gripping space with first loading board 11, avoid circuit board 2 to break away from the centre gripping of second loading board 13 in the great transportation environment of vibrations, when need take out circuit board 2 from loading case 1 through the arm, conveyer belt 4 moves circuit board 2 in loading case 1 and transports to the top of loading case 1, in this motion process, limiting plate 14 will form the centre gripping to circuit board 2 with first loading board 11 cooperation all the time, until limiting plate 14 crosses to touch piece 20 and move to in the recess 19, limiting plate 14 is at this moment to recess 19 inside motion under limiting spring's 15 effect, thereby make limiting plate 14 no longer with first loading board 11 cooperation centre gripping circuit board 2, make things convenient for the manipulator to pick up circuit board 2.
Further, the limiting plate 14 is also rotatably provided with a sliding roller 31, and the sliding roller 31 is abutted against the conveying carrier 6; the friction between the limiting plate 14 and the conveying carrier 6 is reduced by the arrangement of the sliding roller 31.
Furthermore, still slidable mounting has depression bar 28 in loading case 1, depression bar 28 is used for exerting pressure to circuit board 2, and it can be known, because the clamping action of not receiving limiting plate 14 and first loading board 11 of circuit board 2 that is located loading case 1 top, its stability is relatively poor, drop easily in the transportation, through installation depression bar 28, depression bar 28 alternates in loading case 1, and make the one end that depression bar 28 is located loading case 1 suppress at the top of first circuit board 2, thereby make depression bar 28 and first loading board 11 cooperate and carry out the centre gripping to circuit board 2 that is located loading case 1 top, avoid the landing of circuit board 2.
