[0021] This embodiment provides a modular loading machine, including: A frame 1; A conveying mechanism 2, arranged on the frame 1 for conveying a tray 7 containing materials; A lifting mechanism 3, arranged on the frame 1 and docked with the conveying mechanism 2, for receiving the tray 7 conveyed by the conveying mechanism 2 and performing lifting and conveying; A transfer mechanism 4, arranged on the frame 1 and located above the conveying mechanism 2, and the transfer mechanism 4 is used for receiving the tray 7 conveyed by the lifting mechanism 3 and performing horizontal conveyance; A two-way single-control mechanism 5, arranged on the frame 1 and located above the transfer mechanism 4. The two-way single-control mechanism 5 includes a first-direction movement component 50, a second-direction movement component 51 and a single-control component 52. The second-direction movement component 51 slides on the first-direction movement component 50, and the single-control component 52 is arranged according to the contours of the first-direction movement component 50 and the second-direction movement component 51. A clamping mechanism 6 is slidably connected to the second-direction movement component 51. Through the transmission control of the single-control component 52, it is possible to drive the second-direction movement component 51 to reciprocate on the first-direction movement component 50 or drive the clamping mechanism 6 to reciprocate on the second-direction movement component 51. The clamping mechanism 6 is used for sucking and reversing the materials on the tray 7. In this embodiment, the movement direction of the second-direction movement component 51 on the first-direction movement component 50 is defined as the Y direction, and the movement direction of the clamping mechanism 6 on the second-direction movement component 51 is defined as the X direction.

[0022] In this embodiment, further, the conveying mechanism 2 includes a plurality of first conveyor belts 20 arranged in parallel and butt-jointed. The first conveyor belts 20 are drivingly arranged on the frame 1. Adjacent first conveyor belts 20 are butt-jointed and their upper surfaces are on the same horizontal plane for conveying the tray 7. The upstream production line conveys the tray 7 onto the first conveyor belt 20 and then conveys it onto the lifting mechanism 3.

[0023] In this embodiment, further, the lifting mechanism 3 includes a fixing plate 30, a first motor 31, a lead screw 32, a first slider 33, a first slide rail 34, a lifting seat 35 and a second conveyor belt 36. The fixing plate 30 is vertically fixed on the frame 1. The first motor 31 is fixed on the fixing plate 30. The lead screw 32 is drivingly connected to the first motor 31. The lifting seat 35 is in threaded transmission connection with the lead screw 32. The lifting seat 35 is slidably connected to the first slide rail 34 through the first slider 33. The second conveyor belt 36 is fixed on the top of the lifting seat 35 and is used to receive the tray 7 conveyed by the first conveyor belt 20 and lift it to the transfer mechanism 4. When the first motor 31 works, it drives the lead screw 32 to rotate, thereby driving the lifting seat 35 to move up and down.

[0024] In this embodiment, further, the transfer mechanism 4 includes 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. There is a driving connection between the second motor 40 and the rotating shaft 41. On both sides of the frame 1, there are fixed back plates 44. On both ends of the rotating shaft 41, there are fixed belt pulleys 45. The first belt 42 is drivingly connected between the belt pulleys 45 and is close to and attached to the inner side of the back plate 44. The bottom of both sides of the support seat 43 is fixed on the first belt 42.

[0025] In this embodiment, further, the transfer mechanism 4 further includes a carrier seat 47 and a first cylinder 46. The carrier seat 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 its output end is fixedly connected to the bottom of the carrier seat 47.

[0026] In this embodiment, further, a second cylinder 48 is further arranged outside the back plate 44, and a clamping block 49 is arranged inside the back plate 44. The clamping block 49 is fixedly connected to the output end of the second cylinder 48. The second cylinder 48 is used to drive the clamping block 49 to clamp both sides of the tray 7. After the lifting mechanism 3 brings the tray 7 up, the second motor 40 drives the support seat 43 to the bottom of the tray 7. Then, the first cylinder 46 pushes the carrier seat 47 to catch the tray 7, and then the second cylinder 48 pushes the clamping block 49 to clamp the tray 7. After the material ring on the tray 7 is completed, the tray 7 is taken to the side position to be docked with the upstream production line.

[0027] In this embodiment, further, the first-direction movement component 50 includes a second slide rail 500 fixed to the back plate 44. A second slider 501 is slidably disposed on the second slide rail 500. The second-direction movement component 51 includes a third slide rail 510. Both bottoms at the two ends of the third slide rail 510 are fixed to the second slider 501. A third slider 511 is slidably disposed on the third slide rail 510.

[0028] The single-control component 52 includes 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 rotatably disposed at the two ends of the second slide rail 500. The guide wheel 524 is rotatably disposed on the second slider 501 and located on both sides of the third slide rail 510. The second belt 520 is drivingly connected to the rollers 523 and bypasses the guide wheel 524, so that the second belt 520 is wound along the contours of the second slide rail 500 and the third slide rail 510. The third motor 521 and the fourth motor 522 are respectively fixed to the two 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 driving in the same direction and at the same speed, at this time, the second belt 520 is conveyed at a constant speed, and the speed and tension at each part of the second belt 520 are the same. Therefore, the second belt 520 has no component force in the Y direction on the third slide rail 510. Therefore, the third slide rail 510 will not move in the Y direction, and only the clamping mechanism 6 can be moved along the X direction; when the third motor 521 and the fourth motor 522 are driving in the same direction and at different speeds, the section of the second belt 520 near the motor driving part of the motor with the larger speed instantaneously generates a larger tension, so that the second belt 520 generates a radial component force in the Y direction on the adjacent roller 523, thereby pulling the third slide rail 510 to move in the Y direction. By changing the steering, the moving direction can be changed. Thus, through the same-direction and same-speed control of the third motor 521 and the fourth motor 522 on the single-control component 52 of the two-way single-control mechanism 5, the clamping component is driven to reciprocate on the second-direction movement component 51. The same-direction and different-speed control of the third motor 521 and the fourth motor 522 is used to drive the second-direction movement component 51 to move on the first-direction movement component 50. The adjustment movement control in the X and Y directions can be realized by two motors and one belt. The second belt 520 serves as the reference for the linkage between the first-direction movement component 50 and the second-direction movement component 51, and the switching control in two directions is realized with the same reference during the operation, which not only simplifies the mechanism design but also improves the movement accuracy.

[0029] In addition, by adjusting the rotational speed difference between the two motors in real time, the tension fluctuation of the second belt 520 caused by uneven load is automatically compensated, slipping or deviation is avoided, and the stability of long-term operation is improved. By combining algorithms to control the asymmetric speed change of the two motors, curvilinear or oblique path movement (such as circular interpolation) can be achieved, expanding the application in complex scenarios (in addition to reversing the material in this embodiment, it can also achieve functions such as arc sorting or obstacle avoidance). Specifically, the rotational speed difference between the third motor 521 and the fourth motor 522 is dynamically adjusted through algorithms, so that the second belt 520 generates a non-uniform tension distribution in a specific section, thereby applying a resultant force in a composite direction to the third slide rail 510. For example, in circular interpolation movement, the algorithm calculates the target rotational speed difference between the two motors in real time based on the trajectory equation, so that the clamping mechanism 6 is controlled to deviate tangentially to form a continuous curved path. At the same time, the deviation between the actual position and the theoretical trajectory is corrected in a closed loop through a feedback sensor (such as an encoder or a vision system) to achieve high-precision arc sorting or dynamic obstacle avoidance. This control method converts the traditional discrete movement of the XY axis into smooth arbitrary plane trajectory movement, and the complex movement ability can be expanded without additional mechanical structures.

[0030] In this embodiment, further, the clamping mechanism 6 includes a clamping seat 600, the clamping seat 600 is fixed on the third slider 511, a third cylinder 601 is fixed on the clamping seat 600, a positioning seat 602 is fixed at the output end of the third cylinder 601, a fifth motor 603 is provided on the positioning seat 602, a suction nozzle seat 604 is provided at the output end of the fifth motor 603, and a suction nozzle for sucking the material on the tray 7 is provided on the suction nozzle seat 604. After the suction nozzle sucks the material, the fifth motor 603 drives the product to rotate to a set direction and then places it back into the tray 7. Of course, the two-way single-control mechanism 5 and the transfer mechanism 4 can also be extended to be directly connected to the downstream production line, so that the material can be sorted onto the downstream production line, and all can be realized by the modular loading machine of this embodiment.

[0031] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive.
