Further, the feed mechanism 40 also includes a pawl driver 46. The jaw drive 46 is controllable to apply a force in a third direction to the jaw rotation portion 452 to switch the feed jaws 45 between the open and closed states. Specifically, the jaw driving member 46 includes a jaw driving member main body 461 and a telescopic rod 463 extending out of one end of the jaw driving member main body 461, the jaw driving member main body 461 is fixedly connected to the jaw mounting bracket 43, a central axis direction of the telescopic rod 463 extends along the third direction, and the jaw driving member main body 461 can drive the telescopic rod 463 to extend and retract along the third direction, so as to apply an acting force along the third direction to the rotating portion 452 of the feeding jaw 45.

Specifically, in one embodiment, the pressing member 48 is a spring screw.

In this way, the pressing member 48 applies a pushing force acting on the abutting member 47 in the first direction to the abutting member 47, so that the abutting member 47 tends to rotate clockwise around the jaw rotating shaft 44 as a rotating axis, and since the abutting member 47 is fixedly connected to the jaw rotating shaft 44, the jaw rotating shaft 44 tends to rotate clockwise around the first direction under the driving of the abutting member 47, and finally the feeding jaw 45 tends to rotate clockwise around the first direction, and the rotating direction (counterclockwise rotation) of the feeding jaw 45 under the action of the telescopic rod 463 of the jaw driving member 46 is opposite to the rotating direction (clockwise rotation) of the feeding jaw 45 under the action of the pressing member 48.

In this way, the transmission mechanism 50 converts the rotation of the output shaft 23 into the swing of the swing member 52, and further converts the swing into the linear movement of the follower 54 along the second direction, and finally drives the feeding mechanism 40 to move along the slide rail 30 in the second direction.

In some embodiments, the feeder device 100 further comprises a home position detection assembly 60. The origin detection assembly 60 includes an origin detection switch 61 and a shielding member 63, the origin detection switch 61 is fixedly connected to the mounting bracket 14 of the supporting seat 10, the shielding member 63 is sleeved on the output shaft 23, and the shielding member 63 can rotate synchronously with the output shaft 23 to be located at different positions relative to the origin detection switch 61, so as to determine the rotation angle of the output shaft 23.

Specifically, in an embodiment, the origin detection switch 61 includes a signal emitting end and a signal receiving end that are spaced apart and disposed opposite to each other along the first direction, and a detection gap is formed between the signal emitting end and the signal receiving end. The shielding member 63 includes a shielding member connecting portion 632 and a shielding portion 634, the shielding member connecting portion 632 is sleeved on the output shaft 23 and can rotate synchronously with the output shaft 23, the shielding portion 634 is connected to a portion of the edge of the shielding member connecting portion 632 and is in a fan-ring shape, and the shielding member 63 can be switched between a first position located in the detection gap and a second position staggered from the detection gap. When the shutter 63 is switched from the second position to the first position, the shutter portion 634 of the shutter 63 is located in the detection gap, thereby blocking the signal from the signal transmitting terminal from reaching the signal receiving terminal.

More specifically, in one embodiment, the signal transmitting end can emit a light beam, and the signal receiving end is used for receiving the light beam emitted from the signal transmitting end. The shielding member 63 is a light-tight sheet structure, and when the shielding member 63 is located in the detection gap, the shielding member 63 can block the light emitted from the signal emitting end from reaching the signal receiving end, so that the electrical signal of the origin detection switch 61 changes. It is to be understood that the configuration and detection principle of the origin detection switch 61 are not limited thereto, and may be set as needed to meet different requirements.

The working process of the feeding device 100 is as follows:

first, an operator can input a pulse value of the driving motor 20 according to production needs, after the driving motor 20 is powered on, the output shaft 23 rotates around the first direction, and when the shielding portion 634 of the shielding member 63 rotates into the detection gap, the origin detection switch 61 detects a signal change to determine a rotation angle of the output shaft 23.

Then, the output shaft 23 rotates by a certain angle according to the pulse value, and the swinging member 52 is driven to swing to a first preset angle by taking the central axis of the output shaft 23 as a rotating shaft, so as to drive the feeding mechanism 40 to move to a first preset position along the slide rail 30 in the second direction, and at the same time, the jaw driving member 46 drives the rotating portion 452 of the feeding jaw 45 to rotate counterclockwise around the first direction and be in an open state. When the feeding mechanism 40 moves to the first preset position, the acting force of the claw driving piece 46 on the feeding claw 45 disappears, the feeding part 453 of the feeding claw 45 rotates clockwise around the first direction under the action of the pressurizing piece 48 to clamp the material, and in the process of clamping the material, the pressurizing piece 48 continuously applies the acting force on the feeding claw 45 to ensure that the feeding claw 45 continuously applies a certain acting force on the material to prevent the material from separating from the feeding claw 45.

Then, the output shaft 23 rotates by a certain angle in the direction opposite to the previous direction according to the pulse value, and drives the swinging member 52 to swing to a second preset angle by using the output shaft 23 as a rotating shaft, so as to drive the feeding mechanism 40 to move to a second preset position in the second direction along the slide rail 30, and the materials move synchronously under the action of the feeding mechanism 40. When the feeding mechanism 40 moves to the second preset position, the jaw driving member 46 drives the rotating portion 452 of the feeding jaw 45 to rotate counterclockwise around the first direction to separate from the material.

So, above-mentioned process is gone on repeatedly to accomplish the transport in proper order of a plurality of materials. The operator can conveniently set the conveying distance by adjusting the operating parameters (i.e., the pulse values) of the driving motor 20, and particularly, in one embodiment, the material conveying stroke of the feeding device 100 is between 1mm and 50 mm. It is understood that the length of the material conveying stroke of the feeding device 100 is not limited thereto, and can be set as required to meet different production requirements.

According to the feeding device 100, the driving motor 20 is used for driving the feeding claw 45 to move so as to convey materials, an operator can adjust the conveying distance of the materials by adjusting the working parameters of the driving motor 20, and the feeding claw 45 can clamp the materials with different shapes and types, so that the requirements of parametric control can be met while the feeding device has good universality, the conveying efficiency is effectively improved, and the manufacturing cost is reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
