[0009] As a further improvement, the Bar bar pushing and positioning mechanism includes a connecting seat arranged on the third slide, the connecting seat is provided with an L-shaped connecting plate, and the L-shaped connecting plate is provided with a push plate;

[0010] The pneumatic suction nozzle is arranged on the L-shaped connecting plate and is located between the push plate and the connecting seat, and the lower surface of the push plate is higher than the suction end of the pneumatic suction nozzle;

[0011] The top corner of the Bar strip detection platform close to the fixing seat is provided with an inclined chamfer.

[0014] As a further improvement, a Bar bar detection mechanism is provided on the top of the support seat, and the Bar bar detection mechanism extends toward the direction of the Bar bar box positioning and conveying mechanism.

[0015] As a further improvement, the Bar detection mechanism includes a column arranged on the top of the support base, the column is provided with a rotating arm extending toward the positioning plate, the rotating arm is provided with a visual camera, and the visual camera is located above the positioning plate.

[0016] As a further improvement, a second micro-motion platform is provided on the support seat, and the column is arranged on the second micro-motion platform.

[0017] As a further improvement, a coaxial light source is further provided on the support base, and the coaxial light source is located between the visual camera and the positioning plate.

[0018] After adopting the above technical solution, the effects of the present invention are:

[0019] Since the automatic loading and unloading device includes a mounting platform, a Bar bar box positioning and conveying mechanism is slidably installed on the mounting platform along the X-axis, a support seat is provided on one side of the Bar bar box positioning and conveying mechanism, and a Bar bar detection table is slidably installed on the support seat along the Y-axis; a Bar bar three-dimensional transfer mechanism is provided on the mounting platform downstream of the Bar bar box positioning and conveying mechanism. Based on the above structure, the automatic loading and unloading device positions the Bar bar box through the Bar bar box positioning and conveying mechanism during operation, and completes the conveyance of the Bar bars in the Bar bar box at the same time, and then transfers the Bar bars between the Bar bar box and the Bar bar detection table through the Bar bar three-dimensional transfer mechanism.

[0020] In summary, the automatic loading and unloading device is used to realize the mechanized automatic loading and unloading of the Bar strips, which greatly improves the work efficiency. At the same time, the loading and unloading has good stability and high reliability, and will not cause damage to the Bar strips.

[0021] Since the three-dimensional transfer mechanism of the Bar bar includes a fixed seat arranged on the mounting platform, a first slide driven by a first linear drive element is installed on the fixed seat for sliding along the Y-axis, a second slide driven by a second linear drive element is installed on the first slide for sliding along the X-axis, a third slide driven by a third linear drive element is installed on the second slide for sliding along the Z-axis, and a pneumatic suction nozzle is provided on the third slide, so that the movement of the corresponding slide is realized by the drive of each linear drive element, and then the movement of the pneumatic suction nozzle is realized to complete the action of the pneumatic suction nozzle sucking the Bar bar and transferring it between the Bar bar box and the Bar bar detection table. The structure is simple and the pneumatic loading and unloading effect of the Bar bar is good, which effectively avoids the problem of damage to the Bar bar during the loading and unloading process.

[0022] Since a Bar bar pushing and positioning mechanism is provided between the third slide and the Bar bar detection table, the pneumatic suction nozzle is arranged on the Bar bar pushing and positioning mechanism, so that after the Bar bar is loaded through the Bar bar pushing and positioning mechanism, the positioning of the Bar bar on the Bar bar detection table will be completed synchronously.

[0023] Since the Bar bar pushing and positioning mechanism includes a connecting seat arranged on the third slide, an L-shaped connecting plate is arranged on the connecting seat, and a push plate is arranged on the L-shaped connecting plate; the pneumatic suction nozzle is arranged on the L-shaped connecting plate and is located between the push plate and the connecting seat, and the lower surface of the push plate is higher than the suction end of the pneumatic suction nozzle; the top corner of the Bar bar detection table close to the fixed seat is provided with an inclined chamfer, so that after the pneumatic suction nozzle transfers the Bar bar from the Bar bar box to the Bar bar detection table, the connecting seat, the L-shaped connecting plate and the pneumatic suction nozzle move along the X-axis, and during the movement, the pneumatic suction nozzle reaches the inclined chamfer and then descends a certain distance, at which time, the push plate will contact the Bar bar and push it, and the position of the Bar bar on the Bar bar detection table is determined while continuing to move along the X-axis. The structure is simple and the conception is ingenious, and the pneumatic suction nozzle and the push plate are integrated into the same motion mechanism, which saves time and improves efficiency; at the same time, there is no need to set up a separate pushing mechanism, which optimizes the space of the whole machine and reduces costs.

[0024] Since the first fine-motion platform is provided between the third slide and the connecting seat, the fine-tuning of the connecting seat can be achieved through the adjustment of the first fine-motion platform, thereby achieving the fine-tuning of the pneumatic suction nozzle.

[0025] Since the Bar box positioning and conveying mechanism includes a slide driven by the fourth linear drive element, the slide is provided with a positioning plate, and the positioning plate is provided with positioning grooves for positioning multiple Bar boxes. Therefore, during operation, the fourth linear drive element drives the slide to slide, and the slide drives the positioning plate and the Bar box thereon to move toward the direction of the Bar bar three-dimensional transfer mechanism, thereby completing the conveying of the Bar bar. At the same time, during the conveying process, the Bar box is positioned by the positioning groove to ensure the fixed position of the Bar box during movement.

[0026] Since a bar bar detection mechanism is provided on the top of the support seat, the bar bar detection mechanism extends toward the direction of the bar bar box positioning and conveying mechanism, so that the position and quantity of the bar bars in the bar bar box can be identified by the bar bar detection mechanism, laying the foundation for the bar bar three-dimensional transfer mechanism to automatically pick up the bar bars.

[0027] Since the Bar bar detection mechanism includes a column arranged on the top of the support base, the column is provided with a rotating arm extending toward the positioning plate, the rotating arm is provided with a visual camera, and the visual camera is located above the positioning plate, so that the number and relative positions of the Bar bars in the Bar bar box can be photographed by the visual camera for image recognition, the structure is simple, and the recognition effect is good.

[0028] Since the support seat is provided with a second micro-motion platform, and the column is arranged on the second micro-motion platform, the fine adjustment of the photographing position of the visual camera can be achieved through the fine adjustment of the second micro-motion platform.

[0029] Since a coaxial light source is also provided on the support base, and the coaxial light source is located between the visual camera and the positioning plate, fill light is provided during the photographing process through the coaxial light source, thereby providing a guarantee for improving the photographing effect and the image recognition effect.
