Technical Field
[0001] This invention relates to the field of transfer cutting machine manufacturing technology, and more particularly to an automatic assembly machine for transfer cutting machine manufacturing. Background Technology
[0002] Currently, on the production and assembly lines of large agricultural machinery such as transplanters, processes such as precise positioning of the base, pressing of components, and tightening of bolts still largely rely on manual operation or semi-automated equipment. Existing assembly equipment typically uses simple clamps to fix the transplanter base, with limited adjustment range, making it difficult to adapt to the multi-angle installation requirements of different base models. The assembly of components, especially key structures, largely relies on manual control of pneumatic or hydraulic actuators to complete the pressing action, with accuracy depending on operator experience. The bolt tightening process often uses ordinary electric or pneumatic screwdrivers, which have low torque control accuracy and lack effective monitoring of the downward pressure. These separate assembly steps not only require repeated equipment positioning and manual transfer, but also lead to unstable product quality due to fluctuations in operating parameters.
[0003] Existing transplanter assembly technology has several significant drawbacks: First, the base fixing devices are mostly rigid clamps, lacking multi-dimensional fine-tuning capabilities. Even slight deviations in the base or mounting holes can easily lead to misalignment or forced assembly in subsequent assembly, causing stress concentration or component deformation. Second, the component pressing process lacks precise contact force control. Under manual or semi-automatic operation, pressure values fluctuate significantly, easily damaging precision contact surfaces or internal structures due to instantaneous overpressure, or causing misalignment due to insufficient pressure. Third, during bolt tightening, ordinary screwdrivers cannot simultaneously guarantee a constant downward contact force and precise tightening torque. Excessive contact force can crush the mating surfaces of parts, while excessive torque can directly cause bolt stripping or breakage. There is a lack of adaptive stop feedback mechanisms, requiring frequent manual checks to confirm whether tightening is adequate. Fourth, the equipment for each process is scattered and independent, making efficient coordination and continuous flow of positioning, assembly, and tightening actions impossible. This results in prolonged workstation cycles, increased equipment footprint, low overall assembly efficiency, and numerous points of manual intervention. These drawbacks severely restrict the quality stability of transplanter assembly, the level of equipment automation, and the improvement of production cycle time; therefore, we propose an automatic assembly machine for transplanter production to solve this problem.

[0018] The beneficial effects of this invention are as follows:
[0019] 1. In this invention, an automatic assembly machine for transplanting machine production is described. The base of the transplanting machine is placed inside a U-shaped frame, and a cylinder is activated to drive two positioning plates to move closer to each other, so that the positioning plates abut against the outside of the base of the transplanting machine to achieve clamping and positioning. Then, a first drive motor is activated to drive a first lead screw to rotate. The first lead screw drives the slide plate and the U-shaped frame to move horizontally through the threaded transmission with the slide plate. Then, multiple hydraulic cylinders are activated to control the rotation of the upper support plate. A second drive motor is activated to drive a second lead screw to rotate. The second lead screw drives the moving plate to move back and forth through the threaded transmission with the moving plate. The moving plate drives the lower support plate to move back and forth through the bending plate, thereby controlling the back and forth movement of the base of the transplanting machine.
[0020] 2. In this invention, an automatic assembly machine for transplanting machine production uses a third electric push rod to move two clamping plates closer together to clamp transplanting machine parts. A first electric push rod moves a horizontal translation frame, and a second electric push rod moves a lifting plate downwards. The lifting plate moves the mounting box downwards, thereby moving the clamps and transplanting machine parts downwards and assembling the parts into corresponding positions on the base. When a part contacts the base, the base restricts further downward movement of the part, thus restricting the downward movement of the clamps and mounting box. The piston plate continues to move downwards under the action of the lifting plate, thereby driving the counterweight block upwards relative to the mounting box via a flexible belt. During this process, the downward thrust on the mounting box is constant, ensuring constant pressure on the transplanting machine parts relative to the base and preventing pressure damage. When the piston plate contacts the stop button, the controller stops the second electric push rod.
[0021] 3. In this invention, an automatic assembly machine for production of a transfer cutting machine is described. It activates a third drive motor to rotate a third lead screw, which, through threaded transmission with the moving seat, aligns a screwdriver. Then, a fourth electric push rod is activated to move a lifting frame downwards. The lifting frame moves a rotating column, a hexagonal column, a top plate, a torsion motor, and the screwdriver downwards, allowing the screwdriver to insert into the mounting bolt. After insertion, the lifting frame continues to move downwards, causing the rotating column to move downwards relative to the hexagonal column, compressing the connecting spring. Pressure is monitored by a second pressure sensor and a first pressure sensor. When the monitored pressure reaches a preset value, the controller activates a tightening motor to rotate the screwdriver, thus tightening the bolt. As the bolts are tightened, the screwdriver's rotation encounters resistance. When the resistance reaches a certain level, the screwdriver's rotation is restricted, causing the screwdriver motor to start and rotate simultaneously. This, in turn, causes the top plate and hexagonal column to rotate. The hexagonal column then drives the rotating column and winding wheel to rotate synchronously, winding up the pull rope. The pull rope then drives the two counterweight plates upward. During this process, the torque generated by the screwdriver is constant, thus avoiding damage to the bolts. When the counterweight plate contacts the touch button, the controller stops the screwdriver and controls the fourth electric push rod to reset the mounting plate. The controller also controls the third electric push rod to retract, releasing the clamp on the part. The first and second electric push rods are then activated to reset the clamp.
[0022] 4. The automatic assembly machine for transplanter production described in this invention significantly improves the automation level and assembly quality of transplanter assembly through an integrated design of the conveyor module, precision turning mechanism, and multiple sets of collaborative assembly mechanisms. The equipment utilizes multi-directional adjustable fixing and adjusting mechanisms to achieve precise positioning and flexible adjustment of the transplanter base in multiple dimensions, including horizontal movement, forward and backward displacement, and angular tilt, ensuring the base is in the optimal assembly position. The innovative assembly mechanism, through the linkage design of a unique counterweight, flexible belt, piston plate, and stop button, automatically maintains a constant downward pressure on parts during assembly. This effectively prevents damage to precision components from excessive pressing and automatically stops the downward movement when the parts are in place. The screwing mechanism, combined with pressure sensing technology, elastic connection, and a dynamic balancing system of winding wheel and counterweight plate, achieves dual constant control of axial contact force and rotational torque during the screwdriver tightening process, completely avoiding the risk of bolt stripping or breakage. At the same time, a preset touch control mechanism ensures that the machine automatically stops working after the tightening is up to standard. The entire machine optimizes the efficiency of the entire process of positioning, assembly, and fastening through systematic control, greatly reducing the intensity of manual intervention and significantly improving the reliability, consistency, and efficiency of transplanter production.

[0051] In this embodiment, during use, the base of the transplanter is placed inside the U-shaped frame 401, and the cylinder 402 is activated to drive the two positioning plates 403 to move closer to each other, so that the positioning plates 403 abut against the outside of the base of the transplanter to achieve clamping and positioning. Then, the first drive motor 304 is activated to drive the first lead screw 303 to rotate. The first lead screw 303 drives the slide plate 302 and the U-shaped frame 401 to move horizontally through the threaded transmission with the slide plate 302. Then, multiple hydraulic cylinders 307 are activated to control the upper support plate 301 to rotate. The second drive motor 202 is activated to drive the second lead screw 203 to rotate. The second lead screw 203 drives the moving plate 204 to move back and forth through the threaded transmission with the moving plate 204. The moving plate 204 drives the lower support plate 306 to move back and forth through the bending plate 205, thereby controlling the back and forth movement of the transplanter base.
[0052] By activating the third electric push rod 51403, the two clamping plates 51404 are brought closer together to clamp the transplanter parts. By activating the first electric push rod 502, the translation frame is moved horizontally, and the second electric push rod 504 is activated to move the lifting plate 505 downward. The lifting plate 505 moves the mounting box 508 downward, thereby moving the clamp 514 and the transplanter parts downward to assemble the parts into the corresponding positions on the base. When the parts contact the base, the base restricts the parts from moving downward, thereby restricting the clamp 514 and the mounting box 508 from moving downward. The piston plate 507 continues to move downward under the action of the lifting plate 505, thereby driving the counterweight 511 to move upward relative to the mounting box 508 through the flexible belt 510. During this process, the downward thrust on the mounting box 508 is constant, thereby keeping the pressure of the transplanter parts relative to the base constant and avoiding pressure damage. When the piston plate 507 contacts the stop button 512, the controller 8 controls the second electric push rod 504 to stop operating.
[0053] The third drive motor 602 is activated to rotate the third lead screw 603, which, through threaded transmission with the moving seat 604, aligns the screwdriver 709. Then, the fourth electric push rod 702 is activated to move the lifting frame 704 downwards. The lifting frame 704 moves the rotating column 705, hexagonal column 706, top plate 707, torsion motor, and screwdriver 709 downwards, allowing the screwdriver 709 to insert into the mounting bolt. After insertion, the lifting frame 704 continues to move downwards, causing the rotating column 705 to move downwards relative to the hexagonal column 706, compressing the connecting spring 710. Pressure is monitored by the second pressure sensor 711 and the first pressure sensor 703. When the monitored pressure reaches a preset value, the controller 8 activates the tightening motor 708, rotating the screwdriver 709 to tighten the bolt. As the bolt tightens, the screwdriver 709... 9. When the rotation is resisted, the rotation of the screwdriver 709 is restricted when the resistance reaches a certain level. This causes the turning motor 708 to start and rotate itself, which in turn drives the top plate 707 and the hexagonal column 706 to rotate. The hexagonal column 706 drives the rotating column 705 and the winding wheel 713 to rotate synchronously, thereby winding the pull rope 714. The pull rope 714 then drives the two counterweight plates 715 to move upward. During this process, the torque generated by the screwdriver 709 is constant, thus avoiding damage to the bolt. When the counterweight plate 715 contacts the touch button 719, the controller 8 controls the turning motor 708 to stop running and controls the fourth electric push rod 702 to drive the mounting plate 701 to reset. The controller 8 controls the third electric push rod 51403 to retract, releasing the clamp on the part. The first electric push rod 502 and the second electric push rod 504 are started to drive the clamp 514 to reset.
[0054] Through the integrated design of the conveyor module, precision turning mechanism 7, and multiple sets of collaborative assembly mechanisms 5, the automation level and assembly quality of the transplanter assembly are significantly improved. The equipment utilizes a multi-directional adjustable fixing mechanism 4 and an adjusting mechanism 3 to achieve precise positioning and flexible adjustment of the transplanter base in multiple dimensions, including horizontal movement, forward and backward displacement, and angular tilt, ensuring the base is in the optimal assembly position. The innovative assembly mechanism 5, through the linkage design of a unique counterweight 511, flexible belt 510, piston plate 507, and stop button 512, automatically maintains a constant downward pressure on parts during assembly, effectively preventing parts from being crushed. Excessive damage to precision components is prevented, and the downward movement is automatically terminated upon contact with the target position. The screw-turning mechanism 7, combined with pressure sensing technology, elastic connection, and a dynamic balancing system of winding wheel 713 and counterweight plate 715, achieves dual constant control of axial contact force and rotational torque of the screwdriver 709 during bolt tightening. This completely avoids the risk of bolt stripping or breakage. At the same time, a preset touch control mechanism ensures that the machine automatically stops working after tightening to the target. The entire machine optimizes the efficiency of the entire process of positioning, assembly, and fastening through systematic control, significantly reducing the intensity of manual intervention and significantly improving the reliability, consistency, and efficiency of transplanter production.
