[0027] A bracket 1, a guide rail 2 is arranged on the rear side of the bracket 1, and a feed rack 3 is installed inside the guide rail 2, a placement rack 4 is arranged inside the feed rack 3, and a stopper 5 is installed at the lower front side of the feed rack 3, a suspension rope 6 is connected to the top of the feed rack 3, and a pulley 7 is arranged above the feed rack 3, the top of the suspension rope 6 is connected to a winding roller 8 through the pulley 7, the winding roller 8 is arranged on the right side of the guide rail 2, and a ratchet 9 is connected to the outer end of the winding roller 8, a ratchet 10 is arranged above the ratchet 9, and a lever 11 is arranged below the middle of the ratchet 10;

[0028] The electric push rod 12 is arranged at the left end of the guide rail 2, and the right end of the electric push rod 12 is connected to a push plate 13, the upper right side of the electric push rod 12 is connected to a connecting rod 14, and the upper outer end of the connecting rod 14 is fixedly connected to a push rod 15, and a shifting tooth 16 is arranged above the push rod 15.

[0029] like Figure 1 , Figure 3 and Figure 5The middle feed rack 3 forms a lifting mechanism with the bracket 1 through the guide rail 2, and the placement rack 4 is movably connected to the feed rack 3, and a buffer pad is arranged on the top of the feed rack 3 to facilitate the lifting and moving of the placement rack 4, the stopper 5 and the feed rack 3 form a telescopic structure, and the top of the stopper 5 is arranged in an inclined structure, and the placement rack 4 is engaged with the feed rack 3 through the stopper 5, and slots are provided on the placement rack 4 at equal intervals to facilitate the placement of the placement rack 4 at a designated position.

[0030] like Figure 2 , Figure 3 and Figure 4 The middle winding roller 8 is dampedly connected to the bracket 1, and ratchets 9 are symmetrically arranged at the front and rear ends of the winding roller 8 to increase the rotational resistance of the winding roller 8 and facilitate the slow drop of the feeding rack 3. The lever 11 is arranged in a "concave" structure, and the lever 11 and the bracket 1 constitute a sliding structure, which is convenient for the lever 11 to move the ratchet 10 and separate from the ratchet 9. The connecting rod 14 is slidably connected to the bracket 1, and push rods 15 are symmetrically arranged at the front and rear ends of the connecting rod 14 to increase the stability of the operation of the push rod 15. Shift teeth 16 are arranged at equal intervals above the push rod 15, and the shift teeth 16 and the ratchet 9 are arranged correspondingly up and down, which is convenient for the shift teeth 16 to push the ratchet 9 to rotate. The shift teeth 16 are rotationally connected to the push rod 15, and its rotation range is 30°-90°, which is convenient for the unidirectional rotation of the ratchet 9.

[0031] Working principle: When using the feeding device of the circuit board production line, Figure 1 As shown, the circuit board is placed in the card slot of the placement rack 4, and the placement rack 4 is pushed into the feed rack 3. When the feed rack 3 is pushed, the bottom of the placement rack 4 presses the inclined surface of the stopper 5, so that the stopper 5 shrinks on the feed rack 3. After the placement rack 4 is pushed to the specified position, the stopper 5 pops up and resets.

[0032] By starting the electric push rod 12, as Figure 3 and Figure 4 As shown, the electric push rod 12 drives the push plate 13 to move, and pushes the circuit board at the top of the placement rack 4 to move, thereby completing the feeding. At the same time, during the movement of the electric push rod 12, the connecting rod 14 is driven to move, so that the push rod 15 moves. Due to the rotation characteristics of the shifting tooth 16 and the push rod 15, the ratchet 9 squeezes the shifting tooth 16, so that the shifting tooth 16 rotates, and the ratchet 9 is prevented from driving the winding roller 8 to rotate. When the electric push rod 12 is reset, the push plate 13 is driven to reset, and the connecting rod 14 drives the push rod 15 to reset, so that the top of the shifting tooth 16 squeezes the ratchet 9, so that the ratchet 9 drives the winding roller 8 to rotate, so that the winding roller 8 winds the hanging rope 6, pulls the feeding rack 3 to rise, and the ratchet 9 is prevented from rotating in the opposite direction through the action of the pawl 10, so that the next circuit board is raised, which is convenient for the next feeding;

[0033] During the continuous feeding process, Figure 1As shown, the placement rack 4 is driven by the feed rack 3 to move the top of the bracket 1, which is done by squeezing the stop block 5 to facilitate the removal of the placement rack 4, and then by toggling the lever 11, the lever 11 drives the pawl 10 to separate from the ratchet 9, so that the winding roller 8 can rotate under the weight of the feed rack 3, so that the feed rack 3 falls and the feed rack 3 is reset. This is the entire working process of the feeding device of the circuit board production line.
