[0039] Further in the embodiment, the transfer mechanism 4 comprises a second motor 40, a rotating shaft 41, a first belt 42 and a support seat 43, the rotating shaft 41 is rotatably arranged on the frame 1, the second motor 40 is fixed on the frame 1, the second motor 40 is drivingly connected with the rotating shaft 41, back plates 44 are fixed on both sides of the frame 1, pulleys 45 are fixed on both ends of the rotating shaft 41, the first belt 42 is drivingly connected between the pulleys 45 and is close to the inner side of the back plate 44, the support seat 43 is fixed on the first belt 42 at the bottom of both sides.

[0040] Further in the embodiment, the transfer mechanism 4 further comprises a carrier 47 and a first cylinder 46, the carrier 47 is arranged on the upper part of the support seat 43 for carrying the tray 7, the first cylinder 46 is fixed on the support seat 43 and the output end is fixedly connected with the bottom of the carrier 47.

[0041] Further in the embodiment, the back plate 44 further comprises a second cylinder 48 on the outer side, a clamping block 49 is arranged on the inner side of the back plate 44, the clamping block 49 is fixedly connected with the output end of the second cylinder 48, the clamping block 49 clamps the tray 7 through the driving of the second cylinder 48, when the tray 7 is brought up by the lifting mechanism 3, the support seat 43 is driven by the second motor 40 to the bottom of the tray 7, then the first cylinder 46 pushes the carrier 47 to catch the tray 7, the second cylinder 48 pushes the clamping block 49 to clamp the tray 7, when the material on the tray 7 is completed in a ring shape, the tray 7 is brought to the adjacent position to butt joint with the upstream production line.

[0042] Further, the first movement component 50 comprises a second sliding rail 500 fixed on the back plate 44, and a second sliding block 501 slidingly arranged on the second sliding rail 500, and the second movement component 51 comprises a third sliding rail 510 fixed at the bottom of both ends of the second sliding block 501, and a third sliding block 511 slidingly arranged on the third sliding rail 510.

[0043] The single control component 52 comprises a second belt 520, a third motor 521, a fourth motor 522, a plurality of rollers 523 and a guide wheel 524. The rollers 523 are rotationally arranged on both ends of the second sliding rail 500, and the guide wheel 524 is rotationally arranged on the second sliding block 501 and located on both sides of the third sliding rail 510. The second belt 520 is drivingly connected to the rollers 523 and passes through the guide wheel 524, so that the second belt 520 is arranged according to the contour of the second sliding rail 500 and the third sliding rail 510. The third motor 521 and the fourth motor 522 are respectively fixed on both outer sides of the back plate 44 and are respectively drivingly connected to one of the rollers 523. When the third motor 521 and the fourth motor 522 are drivingly connected in the same direction and at the same speed, the second belt 520 is uniformly transmitted at this time, and the speed and tension of the second belt 520 are consistent at each position, so that the second belt 520 does not have a force in the Y direction on the third sliding rail 510, and thus the third sliding rail 510 does not move in the Y direction, but only moves the clamping mechanism 6 in the X direction. When the third motor 521 and the fourth motor 522 are drivingly connected in the same direction and at different speeds, the motor driving part of the motor with a larger speed generates a larger tension on the second belt 520 at that moment, so that the second belt 520 generates a radial force in the Y direction on the roller 523 close to it, thereby pulling the third sliding rail 510 to move in the Y direction, and changing the direction of turning can change the direction of movement, so that the third motor 521 and the fourth motor 522 of the single control mechanism 5 on the two-way single control mechanism 5 are drivingly connected in the same direction and at the same speed, and the clamping component is driven to reciprocatingly move on the second movement component 51, and the third motor 521 and the fourth motor 522 are drivingly connected in the same direction and at different speeds to drive the second movement component 51 to move on the first movement component 50. The two motors and the belt can realize the adjustment and movement control in the X and Y directions. The second belt 520 serves as a reference for the linkage of the first movement component 50 and the second movement component 51, and realizes the switching control in the two directions with the same reference during the action. Not only the mechanism design is simplified, but also the movement precision is improved.

[0044] In addition, by adjusting the speed difference of the two motors in real time, the tension fluctuation of the second belt 520 caused by uneven load is automatically compensated, avoiding slipping or deviation, and improving the stability of long-term operation; combined with algorithm control of two motor asymmetric speed change, curve or inclined path motion (such as arc interpolation) can be realized, and complex scene application can be expanded (in addition to reversing the material in this embodiment, arc sorting or obstacle avoidance can also be realized), specifically, the speed difference of the third motor 521 and the fourth motor 522 is adjusted by algorithm, so that the second belt 520 generates non-uniform tension distribution in a specific section, thereby exerting a composite force on the third slide rail 510. For example, in the arc interpolation motion, the algorithm calculates the target speed difference of the two motors in real time based on the trajectory equation, so that the clamping mechanism 6 is controlled to deviate in the tangent direction, forming a continuous curved path. At the same time, through the feedback sensor (such as encoder or vision system), the deviation between the actual position and the theoretical trajectory is corrected in a closed loop, realizing high-precision arc sorting or dynamic obstacle avoidance. This control method converts traditional XY axis discrete motion into smooth planar arbitrary trajectory motion, without additional mechanical structure, and can expand complex motion capability.

[0045] In this embodiment, further, the clamping mechanism 6 includes a clamping seat 600 fixed on the third sliding block 511, a third cylinder 601 fixed on the clamping seat 600, a positioning seat 602 fixed on the output end of the third cylinder 601, a fifth motor 603 provided on the positioning seat 602, a suction nozzle seat 604 provided on the output end of the fifth motor 603, and a suction nozzle provided on the suction nozzle seat 604 for sucking the material on the material tray 7. After the suction nozzle sucks the material, the fifth motor 603 drives the product to rotate to a set direction and then repositions it into the material tray 7. Of course, the bidirectional single control mechanism 5 and the transfer mechanism 4 can be extended to directly interface to the downstream production line, so as to realize sorting of the material to the downstream production line, which can be realized by the modular feeding machine of this embodiment.

[0046] The embodiments of the application are described above in combination with the drawings, and the embodiments and features in the embodiments in the application can be combined with each other without conflict, the application is not limited to the above specific embodiments, the above specific embodiments are only illustrative, not restrictive, and those skilled in the art can make many forms under the inspiration of the application without departing from the purpose of the application and the scope protected by the claims, which all belong to the protection of the application.
