DETAILED DESCRIPTION

[0025] Embodiment 1, please refer to Figures 1 to 4 It is an assembly identification screening mechanism and conveying production line schematic diagram provided by the utility model.

[0026] The assembly identification screening mechanism comprises a rack 10, a circular vibration assembly 20, a straight vibration feeding assembly 30, a visual identification camera assembly 40 and a recycling assembly 50 arranged on the rack 10. It is conceived that the assembly identification screening mechanism also comprises other functional assemblies and specific structures, such as electrical connection assemblies, control assemblies, mounting structures and the like, which are all known to those skilled in the art, so they will not be described in detail here.

[0027] The rack 10 serves as a mounting carrier, facilitating the combination and installation of various components. In this embodiment, the assembly is exemplified by a rectangular ring-shaped component.

[0028] The circular vibration assembly 20 is a circular vibration disc, and a material placing groove 21 and a circular vibration conveying channel 22 spirally upward along the inner wall of the material placing groove 21 are arranged inside the circular vibration assembly 20. A large number of assemblies are placed in the material placing groove 21 for feeding, and the circular vibration assembly 20 provides a conveying power source through vibration, so that the assemblies are sequentially arranged along the circular vibration conveying channel 22 to form a path for upward conveying. A long-short side screening gap 23 is arranged through the middle of the circular vibration conveying channel 22. It is conceived that when the assemblies move spirally upward along the circular vibration conveying channel 22, the edge of the assemblies away from the inner wall of the material placing groove 21 remains connected to the edge of the inner wall of the material placing groove 21 as a reference edge, and the long-short side screening gap 23 is arranged in the middle. When the edge of the assembly away from the inner wall of the material placing groove 21 cannot be connected to the circular vibration conveying channel 22, the center of gravity of the assembly moves downward and falls from the long-short side screening gap 23 to the material placing groove 21 for recycling and feeding.

[0029] Optimally, the circular vibration conveying channel 22 is provided with a straight conveying section 24, which is arranged in the middle of the circular vibration conveying channel 22 along the conveying direction of the straight conveying section 24. The straight conveying section 24 corresponds to the abutting inner wall of the material, and the long and short edge screening gaps 23 are in the form of strip-shaped holes, which are more stable for the abutting conveying of the rectangular ring-shaped parts and improve the screening accuracy. It is conceivable that multiple straight conveying sections 24 and long and short edge screening gaps 23 can be provided to realize multiple screening and avoid the problem of material jamming.

[0030] In the present embodiment, the straight vibration feeding assembly 30 includes a straight vibration feeding channel 31 connected to the uppermost end of the circular vibration conveying channel 22. The assembled parts screened through the circular vibration conveying channel 22 enter the straight vibration feeding channel 31, and the vibration of the straight vibration feeding assembly 30 provides the conveying power source. The inner diameter of the straight vibration conveying channel is suitable for the passage of single assembled parts. The straight vibration feeding channel 31 is a closed axial conveying channel, and the circumferential outer wall of the assembled part is close to the inner wall of the straight vibration conveying channel for passing through, thereby ensuring the stability of the shape of the assembled part during conveying. A stop blocking groove 32 is arranged at the end of the straight vibration conveying channel. Two assembled parts are in an exposed state in the stop blocking groove 32. The assembled parts stop after being conveyed to the position of the stop blocking groove 32. The exposed stop blocking groove 32 is convenient for cooperation with other components for identification or clamping and transferring operations.

[0031] A material sensing sensor 33 is arranged in the stop blocking groove 32, which identifies whether there are assembled parts in the stop blocking groove 32 or whether the assembled parts are transferred to the specified position, thereby facilitating the joint operation of other components.

[0032] A visual identification camera assembly 40 is arranged above the stop blocking groove 32. Specifically, the visual identification camera assembly 40 includes a camera 41 arranged above the stop, and a ring-shaped light source 42 between the camera 41 and the stop blocking groove 32. The ring-shaped light source 42 provides a light source to illuminate the surface features of the assembled parts. The camera 41 realizes photographing identification and screens the front and back surfaces of the assembled parts. For example, in the present embodiment, the front and back surfaces of the assembled parts are only distinguished by the chamfer structure of the edge.

[0033] A transverse guide rail 43 is further arranged on the rack 10, a transverse sliding block 44 is slidingly arranged on the guide rail, and a transverse driver 45 is arranged to drive the transverse sliding block 44. The transverse driver 45 is a pneumatic cylinder. The visual identification camera assembly 40 is arranged on the transverse sliding block 44. It is conceivable that in order to ensure the accuracy of the visual identification camera assembly 40, the distance between the visual identification camera assembly 40 and the stop blocking groove 32 is close. When the assembled parts are identified as the correct surface, the transverse driver 45 can drive the transverse sliding block 44 to move along the transverse guide rail 43, so that the visual identification camera assembly 40 moves out of the upper part of the stop blocking groove 32, thereby facilitating the mechanical hand to approach and clamp and transfer to the next process.

[0034] When the assembly is identified as a wrong face, the assembly can be removed by the recycling assembly 50. The recycling assembly 50 comprises a collecting hopper 51 arranged on the side of the straight-vibration feeding assembly 30 close to the stop blocking groove 32, and the collecting hopper 51 is used to collect the assembly and then reposition in the material slot 21. A rotating shaft 54 is arranged in the collecting hopper 51, and the rotating shaft 54 is driven by a rotating driver 55 which is a rotating motor. A plurality of material throwing rotating rods 52 are connected to the circumferential outer wall of the rotating shaft 54 and are circumferentially distributed on the rotating shaft 54. The material throwing rotating rods 52 do not interfere with the inner wall of the collecting hopper 51 during rotation. A rotating allowance gap 53 is arranged on the side of the stop blocking groove 32 close to the collecting hopper 51, and the rotating allowance gap 53 communicates with the stop blocking groove 32 and allows the material throwing rotating rods 52 to rotate through. The material throwing rotating rods 52 have a strip structure and can rotate to extend into the bottom of the assembly in the stop blocking groove 32 to drive the assembly to overturn and fall into the collecting hopper 51.

[0035] Optimally, the end of the material throwing rotating rod 52 is provided with a protrusion 56 which rotates to extend into the stop blocking groove 32. The protrusion 56 corresponds to the preliminary positioning of the assembly and has good material following stability during synchronous overturning.

[0036] The rack 10 is also provided with a pressing assembly 60 for pressing the material. Specifically, the pressing assembly 60 comprises a vertical guide rail 61 arranged on the rack 10, a pressing block 62 arranged on the vertical guide rail 61 in a lifting manner, and a pressing driver 63 for driving the pressing block 62. The pressing driver 63 is a pneumatic cylinder. The pressing block 62 is driven by the pressing driver 63 to press downward on the second last assembly in the stop blocking groove 32, so as to prevent the second last assembly from abutting against the last assembly and avoid the problem of material jamming offset under the force of moving and transferring.

[0037] In embodiment 2, the utility model also provides a conveying production line which has the assembly identification and screening mechanism as described above. Except for the assembly identification and screening mechanism, other components are prior art or commercially available components.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the scope defined by the appended claims.
