Detailed Implementation

[0053] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] Example 1: An automatic assembly device for door and window hinges, such as... Figure 1-8 As shown, it includes:

[0056] Assembly table 1, the bottom of the assembly table 1 is provided with a first mounting frame 2, the assembly table 1 is rotatably mounted on the first mounting frame 2 via a shaft, and the first mounting frame 2 is provided with a drive mechanism for driving the assembly table 1 to rotate.

[0057] The feeding mechanism is used to feed the two blades of hinge 30;

[0058] Multiple outer bearing seats 23 are installed on the assembly table 1 in a circumferential distribution. An inner bearing seat 6 is installed inside the outer bearing seat 23. A positioning seat 18 is installed on the inner side of the inner bearing seat 6. The two positioning seats 18 are used to support and transport the two leaves of the hinge 30 respectively.

[0059] The positioning seat 18 is provided with an adjustment groove, and an adjustment block 32 is slidably installed in the adjustment groove. The adjustment block 32 is provided with a set screw for fixing the adjustment block 32 in the adjustment groove. A guide rod 24 is provided on the top of the adjustment block 32, and the guide rod 24 is adapted to the opening 31 of the hinge 30.

[0060] By setting up structures such as the inner bearing seat 6 and the positioning seat 18, the hinge 30 can be positioned by the guide rod 24, thereby achieving reliable conveying. The adjusting block 32 can be adjusted in the adjusting groove and fixed by the set screw, thereby adapting to hinges 30 with different hole positions and improving reliability.

[0061] To facilitate material loading; such as Figure 3 , Figure 4 As shown, the feeding mechanism includes:

[0062] The two feeding channels 19 are both installed on the first mounting frame 2. The inner dimensions of the two feeding channels 19 are adapted to the two blades of the hinge 30. The output port of the feeding channel 19 is adapted to the position of the positioning seat 18.

[0063] Connecting frame 14 is installed on one side of the outer wall of the feeding channel 19;

[0064] U-shaped seat 15 is fixed to the outer wall of one side of the connecting frame 14. Both ends of the inner wall of the U-shaped seat 15 are slidably connected to slide rods 20. One end of the slide rod 20 is fixed to a baffle 16. Two openings are provided on one side of the feeding channel 19. The positions of the two baffles 16 are adapted to the two openings respectively. The distance between the two openings is adapted to the thickness of one leaf of the hinge 30.

[0065] Sliding ball 21 is movably installed in U-shaped seat 15. Multiple sliding balls 21 are connected in series between the ends of two sliding rods 20 by connecting ropes. The two ends of the connecting ropes are fixed to the ends of the two sliding rods 20.

[0066] Electric push cylinder 17 is installed on the outer wall of one side of the feeding channel 19, and the output end of electric push cylinder 17 is fixed on a baffle 16.

[0067] By setting up a feeding mechanism, the two blades of the hinge 30 can be placed in the two feeding channels 19 respectively. When the assembly table 1 rotates and drives the positioning seat 18 to the feeding position, the electric push cylinder 17 works and drives the two baffles 16 to move. During the process, the upper baffle 16 is inserted into the feeding channel 19, thereby blocking the bottom blade from the next bottom blade. At the same time, the upper slide rod 20 moves and can be driven by the sliding ball 21 and the traction rope to drive the lower slide rod 20 to slide, so that the lower baffle 16 slides out of the feeding channel 19, thereby releasing the obstruction of the bottom blade; so that the bottom blade falls into the positioning seat 18 under the guidance of the guide rod 24, realizing the feeding.

[0068] When the electric push cylinder 17 is reset, the two baffles 16 move in opposite directions. The lower baffle 16 re-blocks the output port of the feeding channel 19, while the upper baffle 16 slides out of the feeding channel 19, so that the subsequent blades can fall smoothly onto the top surface of the lower baffle 16 for the next feeding.

[0069] To facilitate adjustment of the position of the positioning seat 18; such as Figure 5 As shown, an end plate 35 is provided on one side of the positioning seat 18, and an adjustment knob 22 is connected to the inner side of the end plate 35 by a thread. One end of the adjustment knob 22 is rotatably installed in the positioning seat 18. A guide ridge 29 is provided on the inner side of the inner bearing seat 6. Sliding grooves are provided on both sides of the positioning seat 18, and the positioning seat 18 slides on the outer wall of the guide ridge 29.

[0070] The end plate 35 and the inner bearing seat 6 are connected by a first spring 25. A limit block 26 is fixed inside the inner bearing seat 6. The limit block 26 is used to limit the end plate 35.

[0071] By setting up structures such as the adjustment knob 22 and the end plate 35, the end plate 35 receives the traction force of the first spring 25 and is limited by the limiting block 26, so the position of the end plate 35 is relatively fixed. The distance between the positioning seat 18 and the end plate 35 can be adjusted by turning the adjustment knob 22, thereby achieving the purpose of adjusting the position of the positioning seat 18, so that it can better cooperate with the feeding and processing according to the actual situation, thus improving its practicality.

[0072] To facilitate the rotation of assembly table 1; such as Figure 2 As shown, the drive mechanism includes:

[0073] The first drive motor 9 is mounted on the first mounting bracket 2;

[0074] Drive gear 10, the shaft of drive gear 10 is connected to the output end of the first drive motor 9;

[0075] Driven gear 8 is mounted on the shaft of assembly table 1 and meshes with drive gear 10.

[0076] To facilitate the installation of the hinge pin of hinge 30; such as Figure 7 , Figure 8 As shown, the inner support seat 6 slides up and down inside the outer support seat 23. A guide post 34 is fixed at the bottom of the inner support seat 6, and a limit plate 12 is fixed at the bottom of the outer support seat 23. The guide post 34 is slidably connected to the inner wall of the limit plate 12, and the guide post 34 and the limit plate 12 are connected by a second spring 33.

[0077] To facilitate the installation of the hinge pin of hinge 30; such as Figure 7 , Figure 8 As shown, a hinge shaft mounting mechanism is provided on one side of the assembly table 1, and the hinge shaft mounting mechanism includes:

[0078] The closing assembly is used to push the inner support 6 downward to the assembly position, and to close the two flaps of the hinge 30 by controlling the closing of the two positioning seats 18;

[0079] The second mounting bracket 3 is located on one side of the assembly table 1, and the second drive motor 7 is mounted on the second mounting bracket 3.

[0080] Rotary disk 27 is rotatably mounted on the second mounting bracket 3 via a shaft. The shaft of the rotating disk 27 is connected to the output end of the second drive motor 7. The rotating disk 27 is provided with circumferentially distributed sleeves 40.

[0081] Hinge shaft feeding device 39 is used to fill the sleeve 40 with hinge shafts. The filling method can be hydraulic cylinder pushing, etc., which will not be described in detail here.

[0082] The first top cylinder 4 is installed on one side of the second mounting bracket 3, and the second top cylinder 38 is installed on the other side of the second mounting bracket 3. The output ends of the first top cylinder 4 and the second top cylinder 38 are both adapted to the position of the uppermost sleeve 40.

[0086] A roller 28 is fixed to the top of the end plate 35, and the position of the roller 28 is adapted to the pressure plate 37;

[0087] By setting a hinge shaft mounting mechanism, when the positioning seat 18 carries the hinge 30 to the assembly station, the pressure plate 37 is pushed downward based on the operation of the first electric telescopic cylinder 5. Then, the two inclined ends of the pressure plate 37 are used to squeeze the roller 28 inward, so that the two positioning seats 18 come together. As the pressure plate 37 continues to press down, the inner bearing seat 6 slides downward against the force of the second spring 33, so that the two leaves of the hinge 30 move to the assembly position.

[0088] The first top cylinder 4 and the second top cylinder 38 work together to install the hinge shaft inside the sleeve 40 between the two blades, thereby achieving assembly.

[0089] Example 2: To facilitate material unloading, this example makes the following improvements based on Example 1: The bottom of the assembly table 1 is provided with a material-lifting mechanism, which includes:
