If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figures 1 to 6 As shown, the utility model provides an automatic box separation mechanism, comprising:

[0033] A box-splitting frame 100 is provided with two mounting platforms distributed up and down, namely a first mounting platform 110 and a second mounting platform 120, wherein a material storage rack 130 is provided on the first mounting platform 110, and a plurality of material-splitting channels 131 are provided in the material storage rack 130, and the two ends of the material-splitting channels 131 are respectively a feeding end and a discharging end, and a material suction assembly 200 is provided on the second mounting platform 120, and a plurality of suction cups 210 are provided at the output end of the material suction assembly 200, and the position of each suction cup 210 corresponds to the position of each material-splitting channel 131;

The output directions of the first sub-box output end and the second sub-box output end are perpendicular to the material falling direction on the sub-box channel 131, and the output direction of the third sub-box output end is consistent with the material falling direction on the sub-box channel 131. The first sub-box output end is used to support the edge of the lowest material box, and the second sub-box output end is inserted into the gap between the lowest material box and the second to last material box to increase the relative gap between the two. The third sub-box output end pushes the edge of the lowest material box to further expand the relative gap between the two.

[0035] When sorting boxes, in the initial test state, the first sorting box output end and the second sorting box output end are both in an extended state, at which time the edge of the lowest box in the sorting channel 131 is placed on the first sorting box output end; then the first sorting box output end retracts, and the second sorting box output end remains stationary, so that the edge of the lowest box in the sorting channel 131 is placed on the second sorting box output end; secondly, the first sorting box output end is extended again and inserted into the gap between the lowest box and the second-to-last box, so that the edge of the second-to-last box is placed on the first sorting box output end; then the second sorting box output end retracts, and at this time the lowest box is in a suspended state; finally, through the downward pressure of the third sorting box output end and the suction of the suction cup 210, the lowest box is separated from the second-to-last box to achieve sorting.

[0037] Preferably, the first sub-box output end, the second sub-box output end and the third sub-box output end in the multiple sub-box parts realize corresponding synchronous movement through the first sub-box cylinder 310, the second sub-box cylinder 320 and the third sub-box cylinder 330 respectively, wherein the output direction of the first sub-box cylinder 310 is perpendicular to the moving direction of the first sub-box output end, the output direction of the second sub-box cylinder 320 is perpendicular to the moving direction of the second sub-box output end, and the output direction of the third sub-box cylinder 330 is consistent with the moving direction of the third sub-box output end.

[0038] In this embodiment, the movement of the sub-box output end is achieved by a cylinder, which improves the stability and accuracy of the sub-box output end during movement. In addition, the output directions of the first sub-box cylinder 310 and the second sub-box cylinder 320 are perpendicular to the movement directions of the first sub-box output end and the second sub-box output end, making the structure of the entire sub-box assembly 300 more compact and reducing the volume of the entire sub-box assembly 300.

[0039] Further preferably, the sub-box assembly 300 includes a sub-box frame 340 which is hollow, and the first sub-box cylinder 310 and the second sub-box cylinder 320 are both connected to the sub-box frame 340, wherein the output ends of the first sub-box cylinder 310 and the second sub-box cylinder 320 extend into the sub-box frame 340 respectively, and are respectively connected with the first sub-box guide rail 350 and the second sub-box guide rail 360, and the first sub-box guide groove 351 and the second sub-box guide groove 361 are respectively arranged on the first sub-box guide rail 350 and the second sub-box guide rail 360, and the two ends of the first sub-box guide groove 351 are distributed front and back along the moving direction of the first sub-box output end, and the two ends of the second sub-box guide groove 361 are distributed front and back along the moving direction of the second sub-box output end, wherein the first sub-box output end and the second sub-box output end form a sliding fit with the first sub-box guide groove 351 and the second sub-box guide groove 361 respectively.

[0040] It is worth mentioning that when the first separation box cylinder 310 drives the first separation box guide rail 350 to move along the blanking direction perpendicular to the material distribution channel 131, the first separation box output end moves in the first separation box guide groove 351, and when the first separation box output end moves to the front position on the first separation box guide groove 351, the first separation box output end is in an extended state, and when the first separation box output end moves to the rear position of the first separation box guide groove 351, the first separation box output end is in a retracted state; since the movement mode of the second separation box cylinder 320, the second separation box guide rail 360, and the second separation box output end is the same as that of the first separation box cylinder 310, the first separation box guide rail 350, and the first separation box output end, they will not be described here.

[0041] In addition, the first sub-box guiding groove 351 and the second sub-box guiding groove 361 are arranged in a Z-shaped structure.

[0042] Further preferably, the first separation box cylinder 310 and the second separation box cylinder 320 are connected to the two ends of the separation box frame 340 along the length direction of the separation box frame 340, and the moving direction of the first separation box guide rail 350 and the second separation box guide rail 360 is consistent with the length direction of the separation box frame 340, wherein, when the first separation box guide groove 351 on the first separation box guide rail 350 and the second separation box guide groove 361 on the second separation box guide rail 360 are projected onto the same horizontal plane, the first separation box guide groove 351 and the second separation box guide groove 361 are symmetrically arranged.

[0043] It is worth mentioning that since the first sub-box guide groove 351 and the second sub-box guide groove 361 are symmetrically arranged in the same horizontal plane, when the output end of the first sub-box cylinder 310 and the output end of the second sub-box cylinder 320 move in opposite directions, that is, when the first sub-box cylinder 310 and the second sub-box cylinder 320 both retract, the output end of the first sub-box and the output end of the second sub-box extend synchronously.

[0044] Further preferably, the first sub-box limit block 311 and the second sub-box limit block 321 are connected to the output ends of the first sub-box cylinder 310 and the second sub-box cylinder 320 respectively, and the first sub-box guide rail 350 and the second sub-box guide rail 360 are connected to the first sub-box limit block 311 and the second sub-box limit block 321 respectively, wherein the first sub-box output end and the second sub-box output end can be synchronously extended when extending, and the first sub-box output end and the second sub-box output end can be asynchronously retracted when retracting.

[0045] It is worth mentioning that, in the initial state, both the first sub-box output end and the second sub-box output end are in an extended state. When the first sub-box output end is retracting, the first sub-box output end moves from the front end to the rear end of the first sub-box guide groove 351, that is, when the first sub-box cylinder 310 is extended, at this time, the second sub-box cylinder 320 cannot be extended, that is, the second sub-box output end cannot be retracted; when the second sub-box output end is retracting, the second sub-box output end moves from the front end to the rear end of the second sub-box guide groove 361, that is, when the second sub-box cylinder 320 is extended, at this time, the first sub-box cylinder 310 cannot be extended, that is, the first sub-box output end cannot be retracted.

[0046] In other words, in the initial state, the first sub-box cylinder 310 and the second sub-box cylinder 320 are both in a retracted state, and at this time, the first sub-box output end and the second sub-box output end are both in an extended state. When the output end of the first sub-box cylinder 310 is extended, the first sub-box limit block 311 and the second sub-box guide rail 360 form an abutment, thereby blocking the extension of the second sub-box cylinder 320, and then blocking the retraction of the second sub-box output end; when the output end of the second sub-box cylinder 320 is extended, the second sub-box limit block 321 and the first sub-box limit plate form an abutment, thereby blocking the extension of the first sub-box cylinder 310, and then blocking the retraction of the first sub-box output end.

[0047] In this embodiment, the first separation box limit block 311 and the second separation box limit block 321 are provided to avoid the synchronous extension of the first separation box cylinder 310 and the second separation box cylinder 320, thereby avoiding the synchronous retraction of the first separation box output end and the second separation box output end, preventing the material boxes in the separation channel 131 from being directly output in a stacked manner, thereby improving the reliability of stacked material box separation.
