Detailed Implementation

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0026] A hinge assembly system, reference Figure 2 The vibratory feeder includes a connecting rod transport vibratory feeder 2. A connecting rod conveyor 9 is connected to the connecting rod transport vibratory feeder 2. The connecting rod transport vibratory feeder 2 is a very common type of transport vibratory feeder. The outlet end of the connecting rod vibratory feeder 2 is connected to a passage that allows the connecting rod to move out while maintaining a certain shape. Two limiting posts 901 are provided at the end of the connecting rod conveyor 9. A first push rod 3 and a second hinge placement seat 10 are respectively provided on both sides of the end of the connecting rod conveyor 9. The first push rod 3 and the second hinge placement seat 10 are respectively connected to the end of the connecting rod conveyor 9.

[0027] refer to Figure 3 The second hinge holder 10 has positioning parts 401 at both ends. The positioning parts 401 have openings 402. The openings 402 are opposite to the first push rod 3.

[0028] It also includes two end-cap transport vibratory feeders 7. The outlets of the end-cap transport vibratory feeders 7 are connected to end-cap conveying channels 8. A first hinge placement seat 4 is provided between the two end-cap conveying channels 8. The first hinge placement seat 4 has the same structure as the second hinge placement seat 10. (Reference) Figure 4The plug conveying channel 8 has an opening on the side near the first hinge placement seat 4, and blocking parts 804 are provided on the inner walls of both sides of the opening. The outer wall of the plug transport vibratory feeder 7 has a corresponding notch, which connects to the opening of the plug conveying channel 8. Blocking parts 804 are also provided on the inner walls of both sides of the notch. The blocking parts 804 do not extend to the bottom of the plug conveying channel 8. A second push rod 5 and a third push rod 6 are respectively provided on the side of the two plug conveying channels 8 away from the first hinge placement seat 4. The bottom of the plug conveying channel 8 connects to the second push rod 5, the third push rod 6, and the first hinge placement seat 4.

[0029] The operator first places the hinge in the second hinge placement seat 10. The connecting rod extends laterally to the end of the connecting rod conveyor 9, and the first push rod 3 inserts the connecting rod into the bushing 1. After the connecting rod is inserted into the bushing 1, the operator places the hinge in the first hinge placement seat 4. The plug is transported by the plug transport vibratory feeder 7 to the end of the plug transport channel 8. Because the diameter of the plug head is larger than the diameter of the end, the plug can only reach the end of the plug transport channel 8 if the end passes through the notch. Plugs whose ends do not pass through the notch can only remain in the plug transport vibratory feeder 7. The plug transport vibratory feeder 7 is existing technology, as is the plug transport channel 8 in this embodiment. The second push rod 5 and the third push rod 6 push the plug transported to the end of the transport channel 8 and install it at both ends of the bushing 1.

[0030] The first push rod 3, the second push rod 5, and the third push rod 6 are hydraulic push rods.

[0031] As a further improvement to the present invention, various novel embodiments can be provided based on the above examples.

[0032] As a second embodiment of the present invention, refer to Figure 5 Based on Embodiment 1, the second hinge placement seat 10 is omitted. A second push rod 5 is provided at the right end of the connecting rod transmission component 9.

[0033] refer to Figure 6 A through-hole 501 is provided at the center of the second push rod 5. The diameter of the through-hole 501 is larger than the diameter of the output port of the connecting rod and the first push rod 3, but smaller than the diameter of the plug head. A first intercepting plate 801 and a second intercepting plate 802 are horizontally slidably arranged in the left plug conveying channel 8. A main gear 803 is arranged between the first intercepting plate 801 and the second intercepting plate 802, meshing with both. A motor for driving the main gear 803 to rotate is provided on the plug conveying channel 8.

[0034] refer to Figure 7The first hinge holder 4 has a positioning part 401 at its left end and a limiting groove 403 at its right end. The limiting groove 403 is open at its upper end. A telescopic rod 404 extending upward is provided at the bottom of the limiting groove 403. A limiting element 405 is provided at the upper end of the telescopic rod 404. The right side of the limiting element 405 is inclined, and the left side is vertical. A return spring 407 is sleeved on the telescopic rod 404. The two ends of the return spring 407 are connected to the limiting element 405 and the bottom wall of the limiting groove 403, respectively.

[0035] When the operator places the hinge on the first hinge holder 4, the second interceptor plate 802 extends while the first interceptor plate 801 remains closed. Due to the presence of the limiting member 405, the connecting rod is blocked, allowing the first push rod 3 to fully insert the connecting rod into the bushing 1. The main gear 803 rotates, causing the second interceptor plate 802 to retract and the first interceptor plate 801 to extend. The last plug falls to the end of the plug conveying channel 8, while the second-to-last plug is blocked by the first interceptor plate 801 and cannot fall. At this point, the second push rod 5 and the third push rod 6 install the plugs at both ends of the bushing 1, thus completing the hinge installation. The second push rod 5 and the third push rod 6 retract, and the main gear 803 rotates back to its original position. At this point, the second interceptor plate 802 extends, the first interceptor plate 801 retracts, and the original second-to-last plug is located on the second interceptor plate 802. The above operation is repeated to install the hinge.

[0036] In a third embodiment of the present invention, the output end sidewall of the second push rod 5 is provided with bevel teeth, and a driven gear is meshed with the sidewall of the second push rod 5. The driven gear is connected to the main gear 803. The transmission method is a relatively existing technology and will not be described in detail here. A belt connection can be used to connect the driven gear and the main gear 803, or multiple gears can be used to connect them, depending on actual requirements. When the second push rod 5 extends, it can drive the main gear 803 to rotate forward, causing the second intercepting plate 802 to retract and the first intercepting plate 801 to extend; when the second push rod 5 retracts, it can drive the main gear 803 to rotate in reverse, causing the second intercepting plate 802 to extend and the first intercepting plate 801 to retract.

[0037] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
