When the disc rotates, the first magnet is driven to intermittently approach the second magnet. Then, under the action of the mutually repulsive magnetic force, the cross bar and the second spring, the movable plate drives the knocking rod to make reciprocating linear motion in the horizontal direction. Then, the knocking rod can repeatedly hit the inner wall of the workbench, causing the unloading position of the workbench to be in a vibrating state, thereby accelerating the unloading process.

[0027] Furthermore, the knocking rods are evenly spaced on the surface of the movable plate, which optimizes the effect of the striking vibration and achieves a better blanking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-6 , the utility model provides the following technical solutions: Automatic assembly device for automobile air-conditioning pipe accessories:

[0037] Example 1: The most basic self-assembly work of the accessories is completed by setting the conveyor belt 5 and the robot arm 2, such as Figure 1 and Figure 2 As shown:

[0038] The machine comprises a workbench 1, a robotic arm 2 is bolted to the upper surface of the workbench 1, a fixed block 3 is fixedly mounted on the upper surface of the workbench 1, a rotating shaft 4 is rotatably provided inside the fixed block 3, and a conveyor belt 5 is sleeved and connected to the surface of the rotating shaft 4. The robotic arm 2 and the rotating shaft 4 are both electrically controlled devices, and the end of the conveyor belt 5 is in contact with the output end of the external feeding device.

[0039] The automatic assembly device for automobile air-conditioning pipe fittings also includes:

[0040] The connecting shaft 6 is rotatably arranged on the front side of the workbench 1, and the upper surface of the workbench 1 is sloped, and a limit column 9 and a material receiving plate 8 are slidably provided inside the workbench 1, and the material receiving plate 8 is fixedly connected to the upper surface of the limit column 9;

[0041] The limit plate 12 is fixedly connected to the surface of the connecting shaft 6, and the surface of the limit plate 12 is in contact with the surface of the workbench 1. The cross bar 17 is fixedly connected to the inner wall of the workbench 1, and the surface of the cross bar 17 is sleeved with the movable plate 15, and the surface of the movable plate 15 is fixedly connected with the knocking rod 18, and the cross bar 17 is symmetrically distributed about the center of the movable plate 15.

[0042] During use, the workbench 1 is loaded with materials through the conveyor belt 5, and the workpiece is clamped and assembled by the robotic arm 2. It has a high degree of automation and high work efficiency. After assembly, the material is released and falls onto the receiving plate 8. Finally, the material slides down under its own gravity, slides off the receiving plate 8, and is collected by the staff.

[0043] Embodiment 2: The difference from embodiment 1 is that the cam 11 is provided to keep the receiving plate 8 in a vibrating state at all times, so as to facilitate the rapid sliding of the material. Figure 3 As shown:

[0044] The surface of the rotating shaft 4 is sleeved with a pulley 7, and the other side of the pulley 7 is sleeved and connected to the surface of the connecting shaft 6, and the surface of the connecting shaft 6 is fixedly connected to a cam 11 corresponding to the receiving plate 8, and the lower surface of the receiving plate 8 is fixedly connected to a first spring 10 that plays an elastic reset role, and the other side of the first spring 10 is fixedly connected to the upper surface of the workbench 1.

[0045] The receiving plate 8 is distributed in an inclined shape, and the inclination angle of the receiving plate 8 is the same as the inclination angle of the middle position of the workbench 1 . The end of the limiting column 9 is convex, and the limiting column 9 is symmetrically distributed about the center of the receiving plate 8 .

[0046] During the material conveying process, the rotating shaft 4 is always in a rotating state, and then the rotating shaft 4 drives the connecting shaft 6 and the cam 11 to rotate through the pulley 7, and then the cam 11 will intermittently press the receiving plate 8. When the cam 11 presses the receiving plate 8, the receiving plate 8 drops. At this time, the first spring 10 is squeezed, and when the cam 11 continues to rotate until it does not contact the receiving plate 8, the receiving plate 8 rises under the action of the first spring 10, and the limiting column 9 makes the receiving plate 8 move only in the vertical direction. Repeat the above process, the receiving plate 8 performs reciprocating linear motion in the vertical direction, and then the receiving plate 8 can unload materials faster, thereby improving work efficiency. When the connecting shaft 6 rotates, the limiting plates 12 distributed on the surface of the connecting shaft 6 limit the rotation position of the connecting shaft 6, thereby ensuring the stability of the rotation of the connecting shaft 6. The receiving plate 8 is inclined, which can also accelerate unloading.

[0047] Embodiment 3: Different from embodiment 2, the setting of movable plate 15 and knocking rod 18 further optimizes the blanking effect, such as Figure 4-Figure 6 As shown:

[0048] The connecting shaft 6 passes through the interior of the workbench 1, and the end of the connecting shaft 6 located inside the workbench 1 is fixedly connected to a disk 13, and the surface of the disk 13 is fixedly connected to a first magnet 14, and the surface of the movable plate 15 is fixedly connected to a second magnet 16, and the magnetic poles on the surface of the second magnet 16 are the same as the magnetic poles at the end of the first magnet 14, and the first magnets 14 are distributed at equal angles on the surface of the disk 13, the knocking rods 18 are distributed at equal intervals on the surface of the movable plate 15, and the surface of the movable plate 15 is fixedly connected to a second spring 19 that plays an elastic reset role, and the other side of the second spring 19 is fixedly connected to the inner wall of the workbench 1.

[0049] When the connecting shaft 6 rotates, the connecting shaft 6 will drive the disc 13 to rotate. When the disc 13 rotates, it will drive the first magnet 14 to intermittently approach the second magnet 16. When the first magnet 14 approaches the second magnet 16, the movable plate 15 will move in the direction of squeezing the second spring 19. When the first magnet 14 continues to rotate away from the second magnet 16, the movable plate 15 moves back under the action of the second spring 19, and the cross bar 17 makes the movable plate 15 move only in the horizontal direction. Repeating the above process, the movable plate 15 drives the knocking rod 18 to perform reciprocating linear motion in the horizontal direction, and then the knocking rod 18 can hit the inner wall of the workbench 1 again and again, so that the unloading position of the workbench 1 is in a vibrating state, thereby accelerating the unloading process.

[0050] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
