[0001] The utility model relates to the technical field of metal-cutting transportation, in particular to an anti-collision structure of a metal-cutting transportation robot. Background Art

[0002] A lock is a locking structure commonly used in decorations. It is usually made of metal through twisting and other processes. Against the background of the rapid development of modern automated processing technology, in order to improve efficiency, most lock processing is carried out using mechanical automation equipment.

[0003] Cutting metal often needs to be transferred between multiple working procedures. In the current automatic processing of cutting metal, in order to improve the efficiency of transfer and save the waste of human resources in transfer, a transport robot is usually configured for transfer, which not only helps to improve efficiency but also avoids problems such as bumps caused by human transfer. However, due to the size limitation of cutting metal, many semi-finished cutting metal parts are often stacked on pallets and then transported by industrial robots. However, the existing transport robots often only take into account their own anti-collision when avoiding collisions, and usually only set up simple fences for pallets during transportation. In a complex workshop environment, pallets are easily affected by external factors, causing the pallets to overturn and damage the cutting metal parts. In view of this, in-depth research was conducted on the above-mentioned problems, resulting in this case. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an implementation scheme: in the modern processing of metal cutting, since the structure of metal cutting is usually relatively small, pallets 3 are often used for batch transportation during transportation. In order to ensure the stability of metal cutting transportation, the existing transportation robot itself is often equipped with an anti-collision structure to avoid obstacles in the workshop. However, the pallet 3 for placing the metal cutting does not have a corresponding obstacle avoidance device, which causes the pallet 3 of the metal cutting transportation robot to collide in some cases.

[0022] In view of the above problems, the present application provides an anti-collision structure of an orifice metal transport robot, the main structure of which is based on a robot chassis 1. The robot chassis 1 adopts a conventional AGV chassis, which can be moved in a workshop through the AGV chassis, and the orifice metal parts are carried to the transfer station. A pushing component 2 is arranged on the robot chassis 1, and a tray 3 is placed on the pushing component 2. The orifice metal parts are placed on the tray 3. The tray 3 can be pushed out by the pushing component 2, so as to achieve the purpose of sending the tray 3 to the transfer station;

[0023] Then, the pushing component 2 specifically uses the cylinder as the power, and limits the adjustment seat 5 through the track to play the role of pushing. The pushing component 2 is provided with an adjustment seat 5, and the adjustment seat 5 is provided with a lifting structure. The lifting structure includes a lifting cylinder 6 and a tray 3 bracket assembled on the adjustment seat 5. The tray 3 bracket supports the tray 3. The lifting cylinder 6 can adjust the lifting of the tray 3 bracket, thereby adjusting the height of the tray 3 to avoid obstacles;

[0024] Furthermore, a plurality of pairs of plug blocks 4 are symmetrically arranged on the bottom surface of the tray 3, a tray 3 bracket is arranged on the telescopic end of the lifting cylinder 6, and a plurality of pairs of slots are opened on the tray 3 bracket corresponding to the plurality of pairs of plug blocks 4, so that the plurality of pairs of plug blocks 4 and the insert sleeves of the slots are mutually limited, so that the tray 3 bracket can stabilize the tray 3 when subjected to horizontal impact, and then a pair of protective seats 8 are symmetrically arranged on the outside of the tray 3 bracket, and the pair of protective seats 8 are arranged in close contact with the two sides of the tray 3, so that when subjected to impact, the force is first transmitted to the protective seats 8 outside the tray 3, and the tray 3 will not be damaged;

[0025] In order to avoid the complete dislocation of the metal parts on the pallet 3 due to excessive impact force, a rotation limiter 9 is arranged on the outside of the adjusting seat 5. The mutual limitation and buffering of the steering limiter and the adjusting seat 5 can make the pallet 3 bracket and the pallet 3 deflect along the force direction when subjected to impact from one side, so as to avoid the overall posture of the transport robot from being shifted, thereby affecting the stability of transportation. A pair of rotating blocks 10 are arranged at the bottom end of the adjusting seat 5, and the pair of rotating blocks 10 are interconnected with the rotation limiter 9.

[0026] As a preferred solution, further, the outer ring of the lifting cylinder 6 is provided with a plurality of auxiliary guide rods 11, and the auxiliary guide rods are telescopic gas strut rod structures and the telescopic ends are connected to the bottom surface of the tray 3 bracket to maintain stability during the lifting process. The telescopic ends of the plurality of telescopic gas strut rods are connected to the tray 3 bracket while the tail ends are assembled on the adjustment seat 5 through rotatable annular plates. When subjected to impact, the telescopic gas strut rods, the tray 3 bracket and the lifting cylinder 6 are synchronized to complete the rotation, so that the long side of the tray 3 rotates to avoid obstacles at a certain angle.

[0027] As a preferred solution, further, several magnetic seats 12 are arranged in several slots, and magnetic blocks are arranged at the ends of the plug-in blocks 4 corresponding to the magnetic seats 12. Through the mutual cooperation between the magnetic blocks and the magnetic seats 12, there is a certain attraction between the magnetic seats 12 and the magnetic blocks, wherein the magnetic seats 12 are electromagnet structures, which maintain stability while eliminating the magnetic force of the magnetic seats 12 when they are out of contact, thereby facilitating the detachment of the tray 3.

[0028] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the above-mentioned rotation limiter 9 includes a pair of arc-shaped slide rails 901, a pair of arc-shaped slide rails 901 are provided on the adjustment seat 5, a pair of arc-shaped sliders 902 are mounted on the pair of arc-shaped slide rails 901, the pair of arc-shaped sliders 902 are connected to the pair of rotating blocks 10 through pins, and a pair of limit springs 903 are symmetrically provided on the arc-shaped slide rails 901 on both sides of the arc-shaped sliders 902;

[0029] In the specific implementation process, a pair of arc-shaped sliders 902 can be limited by a pair of arc-shaped slide rails 901, and a pair of arc-shaped sliders 902 can slide on a pair of arc-shaped slide rails 901. Due to the connection between a pair of rotating blocks 10 and a pair of arc-shaped sliders 902, when the tray 3 and the tray 3 bracket are impacted, the pair of rotating blocks 10 drive the pair of arc-shaped sliders 902 to rotate with the lifting cylinder 6 as the axis, thereby rotating the pair of arc-shaped sliders 902, thereby squeezing or stretching the limit springs 903 to store energy. After breaking away from contact with the obstacle, the stored energy is released, so that the arc-shaped slider 902 drives the rotating block 10 to reset.

[0030] As a preferred solution, further, a curved rod 904 with an arc-shaped structure is arranged at the center of the curved slide rail 901, and a sliding hole matching the curved rod 904 is arranged on the curved slider 902, which plays a limiting role on the curved slider 902 through the guiding and limiting role of the curved rod 904.

[0031] From the above, it can be generally known that the anti-collision structure of the oral metal transport robot is carried by the pallet 3 during the transportation of the oral metal parts. A lifting structure is arranged at the bottom of the pallet 3. The robot's own infrared system detects the surrounding environment and uses the lifting structure to adjust the height of the pallet 3 to avoid obstacles. When an unexpected impact occurs, the position of the pallet 3 is adjusted by rotating the limit switch 9 to prevent the pallet 3 from overturning and affecting the position of the oral metal parts on the pallet 3.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
