[0066] Example 1

[0067] Please refer to Figure 2 This embodiment discloses a transmission assembly device, including a turntable assembly 100, a synchronous material picking assembly unit, and a pawl material picking assembly mechanism 500, a sleeve material picking assembly mechanism 600, a bearing material picking assembly mechanism 700, a pressing mechanism 800 and a material unloading mechanism 900 distributed around the turntable assembly 100. Please refer to Figure 2 and Figure 3 The turntable assembly 100 is mounted on the workbench 130. A plurality of assembly positioning holes 111 are evenly distributed on the circumference of the turntable assembly 100. Each assembly positioning hole 111 corresponds to a workstation. In this embodiment, 8 assembly positioning holes 111 are used as an example, that is, 8 workstations are configured. The 8 workstations are ratchet ring part placement station, crank shaft part assembly station, gasket part assembly station, pawl assembly station, sleeve part assembly station, bearing part assembly station, workpiece pressing station and blanking station, please refer to Figure 2 and Figure 4 The synchronous material picking assembly unit includes a ratchet ring material picking assembly mechanism 200, a crank shaft material picking assembly mechanism 300 and a gasket material picking assembly mechanism 400 installed on the first translation module 234 and located above the turntable assembly 100. Please refer to Figure 2 、 Figure 4 and Figure 5The first working position of the synchronous material picking assembly unit is provided with a ratchet ring feeding mechanism 210, a crank shaft feeding mechanism 310 and a gasket feeding mechanism 410. The second working position of the synchronous material picking assembly unit is adapted to three of the multiple assembly positioning holes 111. The ratchet material picking assembly mechanism 500, the sleeve material picking assembly mechanism 600, the bearing material picking assembly mechanism 700, the clamping mechanism 800 and the unloading mechanism 900 are all installed on the workbench 130 and their positions are adapted to the assembly positioning holes 111. Among them, the first working position of the ratchet material picking assembly mechanism 500 is provided with a sleeve feeding mechanism 610, and the first working position of the bearing material picking assembly mechanism 700 is provided with a bearing feeding mechanism 710.

[0068] The transmission component assembly equipment of this embodiment can be combined with peripheral feeding equipment and other assembly equipment to form a production line, such as a ratchet ring feeding equipment, a crank shaft feeding equipment, a gasket feeding equipment, a sleeve feeding equipment, a bearing feeding equipment, and a clamping assembly assembly equipment. It should be noted that the peripheral feeding equipment and other assembly equipment are not the focus of discussion of this embodiment. Therefore, this embodiment provides too much description of the specific structure of the feeding equipment and other assembly equipment. The feeding equipment and other assembly equipment only have functional connection with the transmission component assembly equipment of this embodiment, and will not affect the structural details of the transmission component assembly equipment of this embodiment.

[0069] During operation, the turntable assembly 100 rotates to shift the assembly positioning holes 111 to different workstations within a circular range, enabling the gradual assembly of the target workpiece. The ratchet ring feed mechanism 210, crankshaft feed mechanism 310, gasket feed mechanism 410, sleeve feed mechanism 610, and bearing feed mechanism 710 each transfer the corresponding parts to be assembled from external equipment to a preset position for collection and assembly. The ratchet ring picking assembly mechanism 200, the crank shaft picking assembly mechanism 300, the gasket picking assembly mechanism 400, the pawl picking assembly mechanism 500, the sleeve picking assembly mechanism 600 and the bearing picking assembly mechanism 700 respectively transfer the corresponding parts to be assembled to different assembly positioning holes 111 of the turntable assembly 100 for parts assembly, wherein the synchronous picking assembly unit realizes the synchronous movement of the ratchet ring picking assembly mechanism 200, the crank shaft picking assembly mechanism 300 and the gasket picking assembly mechanism 400 through the first translation module 234, which is conducive to simplifying the structure of the equipment and reducing the equipment cost.

[0070] The above scheme rotates the workstations through the turntable assembly 100, and realizes automatic material picking and assembly of each workstation through the ratchet ring material picking assembly mechanism 200, the crank shaft material picking assembly mechanism 300, the gasket material picking assembly mechanism 400, the pawl material picking assembly mechanism 500, the sleeve material picking assembly mechanism 600 and the bearing material picking assembly mechanism 700 in cooperation with the ratchet ring feeding mechanism 210, the crank shaft feeding mechanism 310, the gasket feeding mechanism 410, the sleeve feeding mechanism 610 and the bearing feeding mechanism 710, and the target semi-finished workpiece is pressed by the clamping mechanism 800, and the target workpiece is unloaded by the unloading mechanism 900, so that the target workpiece can be automatically assembled, which is beneficial to improving assembly efficiency.

[0071] Please refer to Figure 1 and Figure 3 The turntable assembly 100 includes an upper turntable 110 and a lower turntable 120. An assembly positioning hole 111 is set on the upper turntable 110. The contour shape of the assembly positioning hole 111 is adapted to the ratchet ring part 12. A positioning column 121 is set on the lower turntable 120 and adapted to the position of the assembly positioning hole 111. The crank shaft part 11 can be sleeved on the positioning column 121 to limit the crank shaft part 11 and prevent the crank shaft part 11 from shaking during the rotation of the turntable assembly 100.

[0072] Please refer to Figure 4 and Figure 5 The ratchet ring feeding mechanism 210 includes a first conveyor belt 211, a first positioning guide rail 212, and a first camera 213. The first positioning guide rail 212 is mounted on the first conveyor belt 211. The first camera 213 is mounted below the first conveyor belt 211 and is used to identify the angle of the ratchet ring part 12. The ratchet ring retrieving assembly mechanism 200 includes a first lifting module 201 and a first rotating clamping module 202 connected to each other. The first rotating clamping module 202 is used to adjust the angle of the ratchet ring part 12. The ratchet ring part 12 and the target crankshaft are connected by a spline. During the assembly process, the spline and keyway need to be aligned. When the ratchet ring part 12 moves to a preset position, the first camera 213 identifies the angle of the ratchet ring part 12 to facilitate angle adjustment via the first rotating clamping module 202. It should be noted that the ratchet ring component 12 may be provided with a feature for angle recognition. The angle of angle recognition refers to the angle of the feature used for angle recognition in the horizontal plane relative to the angular coordinate system of the axis of the ratchet ring component 12. The first positioning rail 212 may include a guide rod and a positioning plate. The guide rod is used to guide the movement of the ratchet ring component 12, and the positioning plate is used to stop the ratchet ring component 12 in place, ensuring that the target ratchet ring can move to the preset position.

[0073] Please continue to refer to Figure 4 and Figure 5The crankshaft feeding mechanism 310 includes a first material picking guide rail 311, a second camera 312 and a lifting and rotating clamping claw module 313. The first material picking guide rail 311 is inclined relative to the horizontal plane and a positioning baffle is provided at the end of the first material picking guide rail 311. The second camera 312 is installed below the first material picking guide rail 311. The lifting and rotating clamping claw module 313 is installed on the adjacent side of the end of the first material picking guide rail 311. The lifting and rotating clamping claw module 313 is used to clamp and lift and flip the crankshaft part 11 and then descend, and the angle of the crankshaft part 11 is identified by the second camera 312. The crankshaft material picking assembly mechanism 300 includes a connected second lifting module 301 and a second rotating clamping claw module 302. The second rotating clamping claw module 302 is used to adjust the angle of the crankshaft part 11. The first pick-up guide rail 311 is tilted, leveraging gravity to cause the horizontally positioned crankshaft component 11 to roll until it is stopped by a positioning stop. The elevating rotary clamping jaw module 313 can grip the crankshaft component 11 and adjust it from a horizontal position to a vertical position, facilitating the second camera 312 to identify the angle of the crankshaft component 11 and facilitate gripping by the second rotary clamping jaw module 302. After the second rotary clamping jaw module 302 adjusts the angle of the crankshaft component 11, it aligns the splines and keyways between the crankshaft component 11 and the target ratchet component, facilitating assembly.

[0074] Please continue to refer to Figure 4 and Figure 5The gasket feeding mechanism 410 includes a second material picking guide rail 411, a second positioning guide rail 412 and a pull rod assembly 413. The second positioning guide rail 412 is installed on the second material picking guide rail 411 and a gasket positioning portion 4121 is provided at the end thereof. The pull rod assembly 413 is installed below the second material picking guide rail 411. A one-way rotating lever 4131 is installed on the pull rod assembly 413. For example, a reset torsion spring is connected to the lever 4131, and a stopper is provided in one of the two rotation directions (counterclockwise and clockwise) of the lever 4131 to limit the rotation direction of the lever 4131. The gasket picking assembly mechanism 400 includes a third lifting module 401 and a gasket clamping module 402. The gasket clamping module 402 is used to clamp the gasket part 13 located at the gasket positioning portion 4121. The pull rod assembly 413 can use a cylinder or a motor as a power part. When the gasket part 13 is located in the initial position of the second material picking guide rail 411, the pull rod assembly 413 drives the lever 4131 to move until the lever 4131 abuts against the gasket part 13. Since the lever 4131 can rotate in one direction, the lever 4131 rotates a certain angle under the interference of the gasket part 13, and resets when it moves to the central hollow area of ​​the gasket part 13. Then, the lever 4131 drives the gasket part 13 to move on the second material picking guide rail 411 under the drive of the pull rod assembly 413, and moves to the position of the gasket positioning part 4121 under the guidance of the second positioning guide rail 412 for stop positioning. The gasket clamping module 402 clamps the gasket part 13 and rises under the drive of the third lifting module 401 to realize material picking.

[0075] Please refer to Figure 2 and Figure 6 The ratchet material picking assembly mechanism 500 includes a first rotating platform 501, a fourth lifting module 502, a pressing module 503, a first clamping module 504, and a restraining ring 505. The pressing module 503, the first clamping module 504, and the restraining ring 505 are all mounted on the fourth lifting module 502. The first clamping module 504 is connected to the pressing module 503. The restraining ring 505 is located below the first clamping module 504. The fourth lifting module 502 is mounted on the first rotating platform 501. Because the ratchet assembly 14 is provided with a ratchet and a torsion spring, the ratchet rotates radially outward under the action of the torsion spring, interfering with assembly. The restraining ring 505 can limit the ratchet of the ratchet assembly 14, converging the ratchet within a certain range to facilitate subsequent assembly. The first clamping module 504 clamps the pawl assembly 14 and rises or presses down under the drive of the pressing module 503. The fourth lifting module 502 can drive the pressing module 503, the first clamping module 504 and the constraint ring 505 to rise or fall synchronously. The first rotating table 501 can drive the fourth lifting module 502 to rotate, thereby switching between the material picking position and the assembly position.

[0076] Please refer to Figure 1 、 Figure 2 and Figure 7 The sleeve picking and assembly mechanism 600 includes a second translation module 601, a fifth lifting module 602, and a second clamping module 603. The second clamping module 603 is mounted on the fifth lifting module 602, which is in turn mounted on the second translation module 601. The second clamping module 603 is used to grip the sleeve component 15 and is driven by the fifth lifting module 602 and the second translation module 601 to move upward or downward, thereby achieving position switching and assembly of the sleeve component 15.

[0077] Please continue to refer to Figure 1 、 Figure 2 and Figure 7 The bearing picking assembly mechanism 700 includes a third translation module 701, a sixth lifting module 702, and a third gripper module 703. The third gripper module 703 is mounted on the sixth lifting module 702, which is in turn mounted on the third translation module 701. The third gripper module 703 is used to grip the bearing component 16 and is driven by the sixth lifting module 702 and the third translation module 701 to move upward or downward, thereby switching the position of the sleeve component 15 and assembling it.

[0078] Both the sleeve feed mechanism 610 and the bearing feed mechanism 710 are conveyor belts. The sleeve feed mechanism 610 is used to transfer the sleeve component 15 from an external loading device to a preset position for easy access by the sleeve retrieving assembly mechanism 600. Similarly, the bearing feed mechanism 710 is used to transfer the bearing component 16 from an external loading device to a preset position for easy access. Conveyor belts are commonly used linear transport mechanisms, providing a smooth, reliable transport process with high repeatability, helping to reduce part positioning deviations during the conveying process.

[0079] Please refer to Figure 2 and Figure 8 The clamping mechanism 800 includes a clamping assembly and a pushing assembly (not shown in the figure). The clamping assembly includes a connected pressing rod 801 and a clamping power piece 802. The pressing power piece 802 adopts a cylinder or a motor. The pressing rod 801 is provided with a clearance hole 803 suitable for avoiding the crank shaft part 11. The pushing assembly is located below the turntable assembly 100 and is positioned to match the clamping assembly. The pushing assembly includes a connected pushing cylinder and a pushing plate. The pushing plate can abut the bottom of the turntable assembly 100 under the drive of the pushing cylinder. In order to ensure that the sleeve part 15 and the bearing part 16 can be installed in place, the clamping assembly applies pressure to the sleeve part 15 and the bearing part 16 from top to bottom, wherein the avoidance hole 803 on the pressure rod 801 can avoid the crank shaft part 11 so that the pressure rod 801 can abut against the sleeve part 15 and the bearing part 16, and the pushing assembly can abut against the bottom of the turntable assembly 100 to facilitate the application of reverse thrust from the bottom of the turntable assembly 100, which is beneficial for the turntable assembly 100 to maintain balance during the clamping process.

[0080] Please refer to Figure 2 and Figure 9 The unloading mechanism 900 includes a second rotating platform 901, a seventh lifting module 902, and a fourth clamping module 903. The fourth clamping module 903 is mounted on the seventh lifting module 902, which is in turn mounted on the second rotating platform 901. The fourth clamping module 903 is used to grip the assembled target workpiece and, driven by the seventh lifting module 902 and the second rotating platform 901, rises and rotates until it unloads the workpiece at a predetermined position.

[0081] It is worth mentioning that, without considering the equipment cost, the ratchet ring picking assembly mechanism 200, the crank shaft picking assembly mechanism 300, the gasket picking assembly mechanism 400, the pawl picking assembly mechanism 500, the sleeve picking assembly mechanism 600 and the bearing picking assembly mechanism 700 can all be implemented using ready-made industrial robots.

The ratchet ring material feeding mechanism 210, the crankshaft material feeding mechanism 310, the gasket material feeding mechanism 410, the sleeve material feeding mechanism 610, and the bearing material feeding mechanism 710 are arranged around the turntable assembly 100. The turntable assembly 100 is provided with a plurality of assembly positioning holes 111, each assembly positioning hole 111 corresponding to a work station. For matters not covered in the transmission assembly equipment, please refer to Example 1.

[0085] Please refer to Figure 10 The transmission assembly method includes steps S100 to S400. It should be noted that the numbering of the steps in this embodiment is only for the convenience of review and understanding, and does not limit the execution order of the steps. Figures 2 to 9 Describe the content of each link in detail.

[0086] S100, feeding step: The ratchet ring part 12, the crank shaft part 11, the gasket part 13, the sleeve part 15, and the bearing part 16 are respectively fed to corresponding preset material removal positions by the ratchet ring feeding mechanism 210, the crank shaft feeding mechanism 310, the gasket feeding mechanism 410, the sleeve feeding mechanism 610, and the bearing feeding mechanism 710. The angle of the ratchet ring part 12 is identified by the first camera 213 of the ratchet ring feeding mechanism 210, and the angle of the crank shaft part 11 is identified by the second camera 312 of the crank shaft feeding mechanism 310.

[0087] S200, material picking step: respectively controlling the ratchet ring picking assembly mechanism 200, the crankshaft picking assembly mechanism 300, the gasket picking assembly mechanism 400, the sleeve picking assembly mechanism 600, and the bearing picking assembly mechanism 700 to move to the picking positions corresponding to the ratchet ring feeding mechanism 210, the crankshaft feeding mechanism 310, the gasket feeding mechanism 410, the sleeve feeding mechanism 610, and the bearing feeding mechanism 710, and controlling the ratchet picking assembly mechanism 500 to rotate to a preset angle to pick up materials;

[0088] S300, assembly step: respectively controlling the ratchet ring picking assembly mechanism 200, the crankshaft picking assembly mechanism 300, the gasket picking assembly mechanism 400, the sleeve picking assembly mechanism 600, and the bearing picking assembly mechanism 700 to move to the corresponding assembly positioning holes 111 of the turntable assembly 100 for discharging and assembling, and controlling the pawl picking assembly mechanism 500 to rotate above the corresponding assembly positioning holes 111 of the turntable assembly 100 for discharging and assembling, wherein the ratchet ring picking assembly mechanism 200 and the crankshaft picking assembly mechanism 300 respectively adjust the angles of the ratchet ring part 12 and the crankshaft part 11 during the movement;

[0089] S400 , pressing step: controlling the pressing mechanism 800 to press the target workpiece on the turntable assembly 100 .

[0090] In this embodiment, a plurality of assembly positioning holes 111 are provided on the turntable assembly 100 for fixing target parts. By rotating the turntable assembly 100 , the assembly positioning holes 111 can be switched between different workstations to achieve simultaneous execution of multiple processes. In the conveying link, the ratchet ring part 12, the crank shaft part 11, the gasket part 13, the sleeve part 15 and the bearing part 16 are respectively conveyed to the corresponding preset material picking positions by the ratchet ring feeding mechanism 210, the crank shaft feeding mechanism 310, the gasket feeding mechanism 410, the sleeve feeding mechanism 610 and the bearing feeding mechanism 710, so as to facilitate the subsequent material picking link. Among them, the angle of the ratchet ring part 12 is identified by the first camera 213 of the ratchet ring feeding mechanism 210, and the angle of the crank shaft part 11 is identified by the second camera 312 of the crank shaft feeding mechanism 310, so as to confirm whether the angular positions of the ratchet ring part 12 and the crank shaft part 11 match. In the assembly link, the ratchet ring picking assembly mechanism 200 and the crank shaft picking assembly mechanism 300 respectively adjust the angles of the ratchet ring part 12 and the crank shaft part 11 during the movement, so that the splines and keyways of the ratchet ring part 12 and the crank shaft part 11 can match each other during the assembly process, thereby improving the convenience of assembly. In the material picking and assembly stages, the ratchet ring picking assembly mechanism 200, the crankshaft picking assembly mechanism 300, the gasket picking assembly mechanism 400, the pawl picking assembly mechanism 500, the sleeve picking assembly mechanism 600 and the bearing picking assembly mechanism 700 operate synchronously, which can realize the simultaneous execution of multiple processes and reduce production time. Figure 1 In the exploded structure shown, each retrieving assembly mechanism simply places the corresponding components into the corresponding assembly positioning holes or onto the semi-finished workpiece according to a preset method to complete the assembly at the corresponding station. After the assembly phase is completed, the clamping phase is performed to prevent the impact force generated by the clamping mechanism 800 pressing the target workpiece on the turntable assembly 100 from interfering with the turntable assembly 100, thereby ensuring a smooth assembly process. It is worth mentioning that after the material picking link is completed, the corresponding new target parts are moved to their respective corresponding positions through the ratchet ring feeding mechanism 210, the crank shaft feeding mechanism 310, the gasket feeding mechanism 410, the sleeve feeding mechanism 610 and the bearing feeding mechanism 710, so as to facilitate the next round of material picking link; and during the clamping link, the ratchet ring material picking assembly mechanism 200, the crank shaft material picking assembly mechanism 300, the gasket material picking assembly mechanism 400, the pawl material picking assembly mechanism 500, the sleeve material picking assembly mechanism 600 and the bearing material picking assembly mechanism 700 are controlled to execute the material picking link, which can reduce the waiting time difference between each link, thereby improving production efficiency.

[0091] Through the above scheme, different target parts are transported to their respective preset positions by the ratchet ring feeding mechanism 210, the crankshaft feeding mechanism 310, the gasket feeding mechanism 410, the sleeve feeding mechanism 610, and the bearing feeding mechanism 710. Then, the ratchet ring picking assembly mechanism 200, the crankshaft picking assembly mechanism 300, the gasket picking assembly mechanism 400, the pawl picking assembly mechanism 500, the sleeve picking assembly mechanism 600, and the bearing picking assembly mechanism 700 are used for picking and assembly. The target workpiece is also pressed by the clamping mechanism 800. The angles of the ratchet ring part 12 and the crankshaft part 11 are respectively identified and adjusted to facilitate assembly. This can achieve automated assembly of the target workpiece, which is conducive to improving assembly efficiency.

[0092] Please refer to Figure 5 The crankshaft feeding mechanism 310 further includes a first material taking guide rail 311 and a lifting and rotating clamping claw module 313. The feeding process includes:

[0093] The first material taking guide rail 311 guides and positions the horizontally placed crankshaft part 11 to a preset position;

[0094] The crankshaft component 11 is clamped by the lifting and rotating clamping jaw module 313 and then raised to a preset height position and rotated 90 degrees to adjust the crankshaft component 11 to be placed vertically;

[0095] The second camera 312 is used to perform angle recognition on the crankshaft component 11 .

[0096] For example, in order to facilitate loading, during the loading process, the crankshaft part 11 is in a horizontal position. After the crankshaft part 11 enters the first material picking guide rail 311, the first guide rail guides the horizontally placed crankshaft part 11 to a preset position. For example, the first material picking guide rail 311 is tilted relative to the horizontal plane. After the crankshaft part 11 is placed on the first material picking guide rail 311, the crankshaft part 11 can be driven by its own weight to roll along the first material picking guide rail 311 to the preset position. At this time, the lifting and rotating clamping jaw module 313 is in the preset position. Set the position, clamp the crank shaft part 11 through the lifting and rotating clamping claw module 313 and then move it up to a preset height position to avoid the first material picking guide rail 311 interfering with the rotation trajectory of the crank shaft part 11. The lifting and rotating clamping claw module 313 rotates the crank shaft part 11 90° to adjust the crank shaft part 11 from a horizontal placement state to a vertical placement state. Then, the crank shaft part 11 is angle-recognized by the second camera 312. The feature of the angle recognition can be the spline of the crank shaft part 11, or a feature set on the crank shaft part 11.

[0097] Please refer to Figure 4The ratchet ring material picking assembly mechanism 200, the crank shaft material picking assembly mechanism 300 and the gasket material picking assembly mechanism 400 are all installed on the first translation module 234. The material picking link includes: driving the ratchet ring material picking assembly mechanism 200, the crank shaft material picking assembly mechanism 300 and the gasket material picking assembly mechanism 400 to move synchronously through the first translation module 234.

[0098] For example, the first translation module 234 can achieve synchronous movement of the ratchet ring retrieving assembly mechanism 200, the crankshaft retrieving assembly mechanism 300, and the gasket retrieving assembly mechanism 400, simplifying the mechanism for driving the ratchet ring retrieving assembly mechanism 200, the crankshaft retrieving assembly mechanism 300, and the gasket retrieving assembly mechanism 400 to move in the same direction, thereby reducing control difficulty. In other application examples, the first translation module 234 can be replaced with an XY translation module to achieve bidirectional synchronous movement of the ratchet ring retrieving assembly mechanism 200, the crankshaft retrieving assembly mechanism 300, and the gasket retrieving assembly mechanism 400 in the XY horizontal plane.

[0099] Please refer to Figure 6 The ratchet material picking assembly mechanism 500 includes a first rotating platform 501, a fourth lifting module 502, a pressing module 503, a first clamping module 504 and a restraining ring 505. In the material picking process, the ratchet material picking assembly mechanism 500 is controlled to rotate to a preset angle to pick up the material, including:

[0100] The fourth lifting module 502 drives the pressing module 503, the first clamping module 504 and the restraining ring 505 to rise;

[0101] The first rotating platform 501 drives the fourth lifting module 502, the pressing module 503, the first clamping module 504 and the restraining ring 505 to rotate synchronously to a preset angle position;

[0102] The fourth lifting module 502 drives the pressing module 503, the first clamping module 504 and the restraining ring 505 to descend, so that the restraining ring 505 is sleeved on the pawl assembly 14;

[0103] The first clamping jaw module 504 is controlled to clamp the pawl assembly 14 , and the pawl assembly 14 is lifted by the pressing module 503 so that the pawl of the pawl assembly 14 is located in the restraining ring 505 .

[0104] For example, the pressing die 503, the first clamping die 504, and the restraining ring 505 are all mounted on the fourth lifting die 502, the fourth lifting die 502 is mounted on the first rotating platform 501, and the first clamping die 504 is mounted on the pressing die 503. In some application examples, the first rotating platform 501 can have a first working position and a second working position, the first working position corresponding to the material removal position and the second working position corresponding to the assembly position, i.e., adapted to the assembly positioning hole 111 of the turntable assembly 100; or, in other application examples, the first rotating platform 501 can also have an initial position, which can be set between the first working position and the second working position.

[0105] During the material removal process, the fourth lifting module 502 drives the pressing module 503, the first clamping module 504, and the constraint ring 505 to rise, and the first clamping module 504 and the constraint ring 505 can be lifted to a preset height to avoid the structure on the rotation path and prevent rotation interference. The first rotating platform 501 drives the fourth lifting module 502, the pressing module 503, the first clamping module 504, and the constraint ring 505 to rotate synchronously to a preset angle position, so that the first clamping module 504 and the constraint ring 505 rotate to the first working position. At this time, the first clamping module 504 and the constraint ring 505 are located above the pawl assembly 14. The fourth lifting module 502 drives the pressing module 503, the first clamping module 504, and the constraint ring 505 to descend, so that the constraint ring 505 is sleeved on the pawl assembly 14. At this time, the first clamping module 504 is in an open state and is located on both sides of the pawl assembly 14. The first clamping module 504 is controlled to clamp the pawl assembly 14, and the pawl assembly 14 is lifted by the pressing module 503 so that the pawl of the pawl assembly 14 is located in the restraining ring 505. The restraining ring 505 limits the pawl of the pawl assembly 14 to prevent the pawl from expanding outward and interfering with assembly.

[0106] In the assembly process, the pawl material picking assembly mechanism 500 is controlled to rotate to the assembly positioning hole 111 corresponding to the turntable assembly 100 for material placement and assembly, including:

[0107] The fourth lifting module 502 drives the pressing module 503, the first clamping module 504 and the restraining ring 505 to rise;

[0108] The first rotating platform 501 drives the fourth lifting module 502, the pressing module 503, the first clamping module 504 and the restraining ring 505 to rotate synchronously to the top of the corresponding assembly positioning hole 111 of the turntable assembly 100;

[0109] The fourth lifting module 502 drives the pressing module 503, the first clamping module 504 and the restraining ring 505 to descend, so as to sleeve the pawl assembly 14 on the target semi-finished workpiece located on the turntable assembly 100;

[0110] The pawl assembly 14 is driven downward by the pressing module 503 to assemble the pawl assembly 14 onto the target semi-finished workpiece;

[0111] The first clamping jaw module 504 is controlled to be loosened, and the pressing module 503 , the first clamping jaw module 504 and the restraining ring 505 are driven to rise by the fourth lifting module 502 .

[0112] For example, when the pawl picking assembly mechanism 500 holds the pawl assembly 14, the fourth lifting module 502 drives the pressing module 503, the first clamping module 504, and the restraining ring 505 to rise, so that the pressing module 503, the first clamping module 504, and the restraining ring 505 can be raised to a predetermined height position, thereby avoiding interference during rotation and avoiding interference with the target semi-finished workpiece (such as the crankshaft part 11 assembled in the previous process) on the turntable assembly 100. The first rotating platform 501 drives the fourth lifting module 502, the pressing module 503, the first clamping module 504, and the restraining ring 505 to rotate synchronously to above the corresponding assembly positioning hole 111 of the turntable assembly 100, at which point the pawl assembly 14 is located above the target semi-finished workpiece. The fourth lifting module 502 drives the pressing module 503, the first clamping module 504 and the restraining ring 505 to descend, so that the pawl assembly 14 is sleeved on the target semi-finished workpiece located on the turntable assembly 100. At this time, the pawl assembly 14 and the target semi-finished workpiece are in a sleeved state, but not assembled in place. The pawl assembly 14 is driven downward by the pressing module 503 to assemble the pawl assembly 14 to the target semi-finished workpiece. For example, the pawl assembly 14 is moved downward so that the pawl assembly 14 enters the ratchet ring part 12 of the target semi-finished workpiece, and the pawl of the pawl assembly 14 is stretched outward, thereby abutting against the inner wall of the ratchet ring part 12. At this time, the assembly of the pawl assembly 14 is completed. The first clamping module 504 is controlled to loosen, and the fourth lifting module 502 drives the pressing module 503, the first clamping module 504 and the restraining ring 505 to rise, so that the ratchet material picking assembly mechanism 500 is separated from the target semi-finished workpiece to facilitate the next round of material picking.

[0113] Please refer to Figure 2 and Figure 7 The sleeve picking assembly mechanism 600 includes a second translation module 601, a fifth lifting module 602 and a second clamping module 603. The assembly process includes:

[0114] When the second clamping module 603 is clamping the sleeve part 15, the second clamping module 603 is driven to rise by the fifth lifting module 602;

[0115] The fifth lifting module 602 and the second clamping module 603 are driven by the second translation module 601 to move synchronously to the corresponding assembly positioning hole 111 of the turntable assembly 100;

[0116] The second clamping module 603 is driven down by the fifth lifting module 602 to perform material discharging and assembly;

[0117] The second clamping module 603 is controlled to be loosened, and the second clamping module 603 is driven to rise by the fifth lifting module 602 .

[0118] For example, in the feeding link, the sleeve feeding mechanism 610 transfers the sleeve part 15 to a preset position, and the sleeve picking assembly mechanism 600 clamps the sleeve part 15. The second clamping module 603 is driven to rise by the fifth lifting module 602 to lift the sleeve part 15 to a preset height position to avoid interference between the moving path and the target semi-finished workpiece. The fifth lifting module 602 and the second clamping module 603 are driven to move synchronously to the corresponding assembly positioning hole 111 of the turntable assembly 100 by the second translation module 601. At this time, the sleeve part 15 is located above the target semi-finished workpiece. The second clamping module 603 is driven to descend by the fifth lifting module 602 to perform the material discharge assembly so that the sleeve part 15 is sleeved on the target semi-finished workpiece. The second clamping module 603 is controlled to release, and the second clamping module 603 is driven to rise by the fifth lifting module 602, so that the sleeve picking assembly mechanism 600 is separated from the target semi-finished workpiece.

[0119] Please continue to refer to Figure 2 and Figure 7 The bearing material removal assembly mechanism 700 includes a third translation module 701, a sixth lifting module 702 and a third clamping module 703. The assembly process includes:

[0120] When the third clamping module 703 clamps the bearing component 16, the sixth lifting module 702 drives the third clamping module 703 to rise.

[0121] The third translation module 701 drives the sixth lifting module 702 and the third clamping module 703 to move synchronously to the corresponding assembly positioning hole 111 of the turntable assembly 100;

[0122] The third clamping module 703 is driven down by the sixth lifting module 702 to perform material discharging and assembly;

[0123] The third clamping jaw module 703 is controlled to be loosened, and the third clamping jaw module 703 is driven to rise by the sixth lifting module 702 .

[0124] For example, during the feeding process, the bearing feeding mechanism 710 transfers the bearing component 16 to a preset position, and the bearing material removal assembly mechanism 700 clamps the bearing component 16. Both the bearing feeding mechanism 710 and the sleeve feeding mechanism 610 can utilize conveyor belts. The third clamping module 703 is driven upward by the sixth lifting module 702 to prevent interference between the moving path and the target semi-finished workpiece. The sixth lifting module 702 and the third clamping module 703 are driven synchronously by the third translation module 701 to move above the corresponding assembly positioning hole 111 of the turntable assembly 100. At this point, the bearing component 16 is located above the target semi-finished workpiece. The third clamping module 703 is driven downward by the sixth lifting module 702 to perform material discharge assembly, so that the bearing component 16 is sleeved on the target semi-finished workpiece. The third clamping module 703 is controlled to release, and the third clamping module 703 is driven upward by the sixth lifting module 702, thereby separating the bearing material removal assembly mechanism 700 from the target semi-finished workpiece.

[0125] The clamping mechanism 800 includes a clamping assembly and a pushing assembly. The clamping process includes:

[0126] Control the push assembly to abut against the bottom of the turntable assembly 100;

[0127] The pressing assembly is controlled to press the target semi-finished workpiece located on the turntable assembly 100 from top to bottom.

[0128] For example, during the assembly process of the previous step, the parts on the target semi-finished workpiece have completed the preliminary assembly. In order to ensure that each part can be installed in place, especially the sleeve part 15 and the bearing part 16, it is necessary to apply pressure to the target semi-finished workpiece through the clamping mechanism 800 to ensure that each part is installed in place. During the clamping process, top-down pressure will be applied to the target semi-finished workpiece, and this pressure will also act on the turntable assembly 100. Therefore, a pushing assembly is provided under the turntable assembly 100, and the pushing assembly is controlled to abut against the bottom of the turntable assembly 100, so as to support the turntable assembly 100 and avoid the pressure applied by the clamping assembly causing the turntable assembly 100 to be unbalanced. Please refer to Figure 9 The pressing assembly includes a connected pressing rod 801 and a pressing power member 802. The pressing power member 802 is a cylinder or a motor. The pressing rod 801 is provided with a clearance hole 803 suitable for avoiding the crankshaft part 11. The pressing power member 802 drives the pressing rod 801 to press downward. During the downward pressing process, the pressing rod 801 is inserted into the clearance hole 803 and is placed on the crankshaft part 11, thereby applying pressure to the sleeve part 15 and the bearing part 16.

[0129] Please refer to Figure 2 and Figure 9 , the transmission assembly assembly method further includes:

[0130] Controlling the unloading mechanism 900 to grab the target workpiece from the turntable assembly 100 and rotate it to a preset unloading position;

[0131] The control dial assembly 100 is rotated to switch the working position of the assembly positioning hole 111 .

[0132] For example, the target semi-finished workpiece becomes a finished workpiece, i.e., the target workpiece, after being assembled in the previous process. A blanking mechanism 900 is also arranged on the peripheral side of the turntable assembly 100. The blanking mechanism 900 performs the action of the blanking link, i.e., controls the blanking mechanism 900 to grab the target workpiece from the turntable assembly 100 and rotate it to the preset blanking position, so that the assembled target workpiece can be unloaded from the turntable assembly 100. After the target semi-finished workpiece is separated from the turntable assembly 100, the station switching link can be executed, i.e., controls the turntable assembly 100 to rotate to switch the working position of the assembly positioning hole 111. In this way, automated blanking and station switching can be realized, continuous automated production can be achieved, and production efficiency can be improved.

[0133] Please continue to refer to Figure 2 and Figure 9 The unloading mechanism 900 includes a second rotating platform 901, a seventh lifting module 902 and a fourth clamping module 903. The unloading mechanism 900 is controlled to grab the target workpiece from the turntable assembly 100 and rotate it to a preset unloading position, including:

[0134] The fourth clamping module 903 is driven to descend and clamp the target workpiece by the seventh lifting module 902;

[0135] The fourth clamping module 903 is driven to rise by the seventh lifting module 902;

[0136] The seventh lifting module 902 and the fourth clamping module 903 are driven to rotate to a preset angle position by the second rotating platform 901;

[0137] The fourth clamping module 903 is driven by the seventh lifting module 902 to descend to a preset height and then released.

[0138] For example, in some application examples, the second rotating table 901 has a first working position and a second working position, the first working position corresponds to the material picking position, that is, the fourth clamping jaw module 903 is located above the corresponding assembly positioning hole 111 of the turntable assembly 100, and the second working position corresponds to the material unloading position; or, in other application examples, the second rotating table 901 also has an initial position, which is between the first working position and the second working position. When the fourth clamping module 903 is in the first working position, the seventh lifting module 902 drives the fourth clamping module 903 to descend and clamp the target workpiece, so that the target workpiece can be clamped. The seventh lifting module 902 drives the fourth clamping module 903 to rise, so that the target workpiece can be driven to separate from the turntable assembly 100. The second rotating table 901 drives the seventh lifting module 902 and the fourth clamping module 903 to rotate to a preset angle position to transfer the target workpiece to the second working position of the second rotating table 901. The seventh lifting module 902 drives the fourth clamping module 903 to descend to a preset height and then release it, thereby lowering the target workpiece to a preset height position to facilitate the subsequent unloading action.
