Furthermore, the first one-way transmission mechanism comprises a first ratchet wheel, a first pawl and a first elastic sheet, the first pawl is rotatably connected to the first feeding plate, and the first elastic sheet is arranged on the first feeding plate and used for pushing the first pawl to abut against the outer peripheral wall of the first ratchet wheel;
the second one-way transmission mechanism comprises a second ratchet wheel, a second pawl and a second elastic sheet, the second pawl is rotatably connected to the second feeding plate, and the second elastic sheet is installed on the second feeding plate and used for pushing the second pawl to abut against the outer peripheral wall of the second ratchet wheel.
The first ratchet wheel and the second ratchet wheel are sleeved on the driving shaft and are distributed along the axial direction of the driving shaft, and the rotation directions of the ratchet wheel teeth of the first ratchet wheel and the second ratchet wheel are opposite.
In the present invention, the first direction may be a clockwise direction, and the second direction may be a counterclockwise direction. When the motor drives the driving shaft to rotate clockwise, the first ratchet wheel rotates clockwise, when the first pawl is in contact with ratchet teeth of the first ratchet wheel, the direction between the first pawl and the ratchet teeth of the first ratchet wheel is the circumferential tangential direction, the first elastic sheet cannot be bounced open by radial force so as to abut against the first pawl, the first pawl is inserted into a tooth groove of the first ratchet wheel, and the first ratchet wheel drives the first feeding disc to rotate clockwise; meanwhile, the second ratchet wheel also rotates clockwise, when the second pawl is in contact with the ratchet wheel teeth of the second ratchet wheel, the direction between the second pawl and the ratchet wheel teeth is radial, the second elastic sheet is bounced off, the second pawl slides on the tooth back of the second ratchet wheel, and the second feeding disc keeps static.

When the first feeding disc rotates clockwise, when the ratchet teeth of the third ratchet wheel are in contact with the third pawl, the direction between the first feeding disc and the third pawl is radial, the third elastic sheet is bounced off, the third pawl slides on the back of the teeth of the third ratchet wheel, the first feeding disc can continue to rotate clockwise, if the first feeding disc rotates anticlockwise, when the third pawl is in contact with the ratchet teeth of the third ratchet wheel, the direction between the third pawl and the third pawl is circumferential tangential direction, the third elastic sheet cannot be bounced off by radial force so as to support the third pawl, and at the moment, the third pawl is inserted into the tooth groove of the third ratchet wheel to prevent the first feeding disc from continuing to rotate anticlockwise.
In a similar way, when the second feed table anticlockwise rotates, when the ratchet tooth and the fourth pawl contact of fourth ratchet, the direction of force is radial between the two, the fourth shell fragment is opened by the bullet, the fourth pawl slides on the back of the body at the tooth of fourth ratchet, the second feed table can continue anticlockwise rotation, if the second feed table clockwise rotates, when the ratchet tooth contact of fourth pawl and fourth ratchet, the direction of force between the two is circumference tangential direction, thereby the fourth shell fragment can not receive radial power and the bullet is opened and can support the fourth pawl, the tooth's socket that the fourth pawl inserted the fourth ratchet at this moment can prevent the second feed table to continue clockwise rotation.
Further, the first pawl and the second pawl are in a hook shape, and when the first pawl and the second pawl are respectively engaged with the matched ratchet teeth, the hinge points of the first pawl and the second pawl are positioned on the back sides of the teeth of the matched ratchet teeth, and the hook-shaped pawls can generate larger biting force when being engaged with the ratchet teeth.

When a large-diameter solder ball is needed to be welded, the motor drives the driving shaft 1 to rotate anticlockwise to drive the second ratchet wheel 401 to rotate anticlockwise, the second ratchet wheel 401 and the second pawl 402 are matched to drive the second feeding disc 202 to rotate anticlockwise to convey the solder ball, at the moment, the first ratchet wheel 301 also rotates anticlockwise, the first pawl 302 is in contact with the ratchet teeth of the first ratchet wheel 301, the direction between the first ratchet wheel and the second ratchet wheel is radial, the first elastic sheet 303 is bounced off, the first feeding disc 201 is kept static, and due to the existence of the first anti-reverse mechanism 5, the static state of the first feeding disc 201 is further ensured, and the first feeding disc 201 and the second feeding disc 202 are prevented from feeding reversely at the same time.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
