Towards;

(5) When the direction needs to be reversed, the corresponding jacking cylinder 631 drives the push block 632 to move upwards, and the push block 632 lifts the two ends of the bar A upwards and separates from the transmission table 51, and after it is placed on the vacuum adsorption member 61, it passes through the vacuum The adsorption part 61 is adsorbed and fixed, and then reset after rotating 180° by the rotating motor 62, the vacuum adsorption part 61 breaks the vacuum, the push block 632 resets with the fall of the jacking cylinder 631, and the bar A also falls to the original position;

(6) After reversing, if it is a defective product (such as a broken bar A, etc.), it will be dropped into the defective product bin along the end of the conveyor table 51; if it is a good product, it will be driven by the displacement structure 71 and the two-way carrying structure 72 Transfer to the material chamber of the end surface grinder; specifically, the displacement structure 71 drives the grabbing piece 725 to absorb the upper bar A, the driving piece 722 drives the roller 723 to rotate, and the ring-shaped toothed belt 724 drives the grabbing piece 725 to move up and down synchronously. The moving directions of the grippers 725 are parallel and opposite, so when one of the grippers 725 places the bar A on the end grinder (in a high position), the other gripper 725 is in a low position to grab the bar on the transfer table 51 A, such repeated movements not only improve the efficiency, but also have better stability; it should be noted that, in order to prevent interference during the movement of the two grippers 725 and improve stability, the base plate 721 is provided with two grippers. 725 avoids the arc-shaped guide groove 721A, so as to ensure that the mutual movement of the two will not interfere;

In this way, the automatic processing of bar A is completed by sequential transmission and displacement.

The invention provides an automatic production equipment for bar grinding, which is simple in structure, easy to manufacture, easy to implement and low in cost, and solves the problem of cumbersome bar grinding procedures, low efficiency, high defective rate and difficulty in mass production The problem of demand; the present invention integrates the existing bar processing procedures and realizes automatic processing, that is, the material is automatically unloaded through the feeding hopper, and after being ground by the first grinder, cleaning is carried out during the conveying process by cleaning the conveying components, which improves the existing Manual cleaning has disadvantages such as uncleanness, large labor force, low efficiency, and easy misplacement, which greatly improves efficiency and accuracy, and facilitates accurate collection, analysis, and data storage of bar characteristics by subsequent detection components (helpful for subsequent traceability) Defective products); In addition, the uniform direction of the bar is realized through the reversing component, and it is not easy to produce processing errors and other prior phenomena during the subsequent end face grinding, which cannot be realized by manual screening. Manual screening errors often occur, resulting in high-speed The rotating grinding wheel bursts, and it is easy to hurt other people or other equipment after flying out, which is very dangerous. Now most of the methods are to improve the direction accuracy through multiple inspections by multiple personnel, but this method is time-consuming and labor-intensive, and is very cumbersome; The material component transfers the good product to the second grinding machine for end grinding or transfers it to the defective product bin; the whole structure design and layout of the present invention are ingenious, and multiple mechanisms share one transmission mechanism, which shortens the carrying distance, and can be used from the bar material to the end surface The grinding time is shortened by at least 10 times, the efficiency is greatly improved, and the yield rate is improved, and more importantly, a large amount of manual participation is reduced; the invention also includes a material storage component, which is used to cache the rods and ensure the detection of loading. Continuity, it can also be convenient for subsequent batches to be carried to the detection component for transmission, avoiding the shutdown during detection, and the risk of stacking, extrusion damage and other risks caused by the inability of the bar to enter; the invention realizes conveying, washing, The drying is completed in sequence, and the actions of each process are realized without stopping the machine, which improves the efficiency and surpasses the effect of manual dust removal; not only that, but also drives the rod body to rotate during the washing and drying process, realizing full Azimuth cleaning and drying, follow-up accurate detection after defecation; the invention sets two sets of image acquisition units, and detects the axial and radial directions of the bar, which not only realizes end face detection and size detection, but also can identify whether the direction is Placement errors need to be reversed. Compared with manual picking, it is more accurate and has higher precision. Bars with an error setting value of 0.05mm can be set as unqualified products, and the defective products will be recovered at the end of the conveyor table of the detection component. In the silo; the blanking assembly of the present invention includes a displacement structure and a two-way carrying structure, the displacement structure is used to drive the product to translate on the X and Y axes on the horizontal plane, and the two-way carrying structure realizes the Z-axis displacement, and the two-way carrying structure It can be used to improve the height difference between the transfer table and the centerless grinding machine, and through the function of the double-arc guide rail, it can avoid the interference between the two during operation. While improving the efficiency, it can solve the problem that the height difference is difficult to carry or a new The transmission mechanism to achieve the problem, the whole structure design is ingenious, and the volume is small, and the occupied area is small.

The descriptions of the above specifications and examples are used to explain the scope of protection of the present invention, but are not intended to limit the scope of protection of the present invention.
