[0028] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] See Figures 1 to 5 This utility model provides an embodiment of a dual-gear synchronous assembly machine, used to install two gears into a housing for attachment. Figure 1 For reference, the two vertical directions on the horizontal plane are defined as the X and Y directions, and the vertical direction as the Z direction. This integrated machine includes a gear feeding device 1, a transfer device 2, a gear transfer device 3, and a pushing device 4. Except for the transfer device 2, each of the other devices is configured in two sets, with the transfer device 2 positioned on the Y-axis. The feeding device 1, gear transfer device 3, and pushing device 4 are symmetrically arranged on both sides of the transfer device 2 in the X-axis direction. This employs a dual-station collaborative operation to achieve synchronous meshing and assembly of the two gears, ensuring the accuracy and stability of gear meshing and reducing assembly errors. Understandably, a control module (not shown), such as an existing PLC control program, is also provided to automatically control the collaborative operation between the devices, achieving automated and efficient production.

[0030] See Figure 1 and 2 Two sets of gear feeding devices 1 are arranged side-by-side along the X-direction. Each set of gear feeding devices 1 includes a vibratory feeder 11 for sorting gears and a vibratory flow channel 12 for conveying gears to the loading station A. The vibratory flow channel 12 extends along the Y-direction and has a material trough 121 with an inverted "T" shape. The vibratory feeder sorts the gears into a specific state and then conveys them to the vibratory flow channel 12. A linear vibrator 122 is installed at the bottom of the vibratory flow channel 12 to generate vibration at a specific frequency, thereby causing the gears placed in the material trough 121 to move orderly towards the material outlet 1211 of the material trough 121. The material sorting state of the vibratory feeder is the same as the operating principle of existing vibratory feeders, and will not be described again here.

[0031] See Figure 2 and 3 A material distribution component 13 is provided at the material outlet 1211 of the material trough 121, which is used to move the gears one by one from the material outlet 1211 to the loading station A, so that the gear transfer device 3 can grab them. The material distribution assembly 13 includes a material distribution block 131 that docks with the material trough 121, and a material distribution cylinder 132 for driving the material distribution block 131 to move along the X direction. The material distribution block 131 has a receiving groove 1311 that docks with the material trough outlet 1211 and picks up gears one by one. When the material distribution cylinder 132 drives the material distribution block 131 with its gears to the loading station A, the material distribution block 131 closes the material trough outlet 1211 to prevent the gears from continuing to output. When the gear transfer device 3 picks up the gears located at the loading station A, the material distribution cylinder 132 drives the material distribution block 131 to reset, so that the receiving groove 1311 docks with the material trough outlet 1211 again to pick up a gear, and so on.

[0032] See Figure 2 and 4 The transfer device 2 includes a contour positioning component 21 with a positioning cavity 211 and a transfer cylinder 22 for driving the contour positioning component 21 to reciprocate between the assembly station B and the unloading station C. The contour positioning component 21 has transfer channels 212 on both sides in the X direction for two gears to enter the positioning cavity 211. The positioning cavity 211 is adapted to the housing, and the two transfer channels 212 are adapted to the two gears respectively. At the same time, the two transfer channels 212 are connected to the positioning cavity 211, so that the gears placed on the transfer channels 212 can be pushed into the housing of the positioning cavity 211 under the action of the pusher device 4 to realize the assembly of the gears.

[0033] Meanwhile, the transfer device 2 also includes a support frame 23 arranged along the Y direction. The transfer cylinder 22 is a rodless cylinder mounted on the support frame 23. A chain plate line 24 connected to the piston of the transfer cylinder 22 is provided on one side of the support frame 23 in the X direction. The contour positioning component 21 is connected to the piston of the transfer cylinder 22 via a fixed base 25, achieving stable movement of the contour positioning component 21. Furthermore, the contour positioning component is detachably mounted on the fixed base 25, allowing for quick switching between different product models by replacing contour positioning components of different specifications, thus improving production flexibility.

[0034] See Figure 1 The two sets of gear transfer devices 3 are modularly configured, symmetrically arranged on both sides of the transfer device 2 in the X direction via two portal brackets 31, to achieve synchronous assembly of the two gears. (See reference...) Figure 5 Each gear transfer device 3 includes a clamping assembly 32, a Z-axis drive cylinder 33 for driving the clamping assembly 32 to move along the Z-axis, and a Y-axis drive cylinder 34 for driving the Z-axis drive cylinder 33 to move along the Y-axis. The clamping assembly 32 includes a gripper 321 and a gripper cylinder 322 for driving the gripper 321 to open and close. The gripper cylinder 322 is connected to the piston of the Z-axis drive cylinder 33 via a fixing plate 323. The Y-axis drive cylinder 34 is a rodless cylinder located on the top of the portal frame 31 and facing the transfer device 2. The Z-axis drive cylinder 33 is located on the piston of the Y-axis drive cylinder 34. The Z-axis drive cylinder 33 and the Y-axis drive cylinder 34 are used to enable the clamping assembly 32 to move in the Y and Z directions.

[0035] Two portal-shaped supports 31 are each provided with a horizontal support plate 41 in the middle. Two sets of pushing devices 4 are respectively provided on the two horizontal support plates 41. Each set of pushing devices 4 includes a pushing block 42 corresponding to the transplanting channel 212, and a slide cylinder 43 provided on the horizontal support plate 41 for driving the pushing block 42 to move in the X direction. At the same time, the pushing block 42 is provided with a groove 421 on the side facing the transplanting channel 212 that matches the contour of the gear to prevent the gear from rotating during the pushing process.

[0036] Furthermore, each of the pusher devices 4 is also provided with an NG throwing assembly 5 on its top, which is used to receive the defective gears grabbed by the gear transfer device 3. The NG throwing assembly 5 includes an NG material box 51 arranged in the same direction as the pusher block 42, and a dual-axis cylinder 52 located on the top of the moving table of the slide cylinder 43 for driving the NG material box 51 to move in the X direction.

[0037] It should be noted that this embodiment will also include sensors controlled by the control module to detect the state of materials at various locations, enabling the integrated machine of this embodiment to operate autonomously and achieve automation. Furthermore, in this embodiment, the drive mechanism uniformly adopts a cylinder drive scheme. Cylinder drives are characterized by simple structure and fast response speed. Compared with servo motor drives, they are lower in cost, have a shorter installation and debugging cycle, and can quickly adapt to different assembly requirements.

[0038] In summary, the dual-gear synchronous assembly machine provided by this utility model adopts a dual-station collaborative operation to achieve synchronous meshing and assembly of two gears, ensuring the accuracy and stability of gear meshing and reducing assembly errors. The automated assembly process significantly shortens assembly time, reduces manual operation, and improves production efficiency. By changing different specifications of contour positioning parts, different product models can be quickly switched to production, improving production flexibility. In addition, the drive mechanism of each device in this application uniformly adopts a cylinder drive scheme, which has significant advantages in achieving the dual goals of stable operation and cost optimization.
