[0045] Please refer to Figure 1 And Figure 4 A tray conveying device is provided in the embodiment, which comprises a shell, a first conveying part 1 and a second conveying part 2, the shell has an opening, the first conveying part 1 comprises a loading platform 11 for carrying a tray 100, the loading platform 11 is pullably arranged at the opening, and the first conveying part 1 is used for transplanting the tray 100 between the inside and outside of the shell, the second conveying part 2 is arranged in the inside of the shell and is in butt joint with the first conveying part 1, and is used for transporting the tray 100.
[0046] It can be understood that the carrier 11 can be pulled out of the shell in a pulling manner, so that the carrier 11 can be placed in the field of view of the operator, so that the operator can observe the posture of the tray 100 during the feeding and discharging process. The second conveying part 2 can be connected with the first conveying part 1, so as to receive the tray 100 conveyed by the carrier 11, or to convey the tray 100 to the carrier 11. In this way, the feeding and discharging efficiency of the tray 100 can be improved, and the conveying accuracy of the tray 100 can be ensured.
[0047] It should be noted that during the feeding and discharging process, the operator can pull the carrier 11 like a drawer to complete the transportation of the tray 100 between the inside and outside of the shell. Of course, in some other feasible embodiments, the carrier 11 can also be driven by the existing linear driving structure to drive the carrier 11 to perform the pulling action, which will not be described here.
[0048] Among them, the tray 100 extends to the outside of the carrier 11 on both sides along the first direction; the second conveying part 2 includes two conveying mechanisms 21, which are arranged at intervals along the first direction and abut and convey the tray 100 from both sides. It can be understood that when placing the tray 100, it is ensured that the opposite sides of the tray 100 can extend to the outside of the carrier 11, so that the tray 100 can be lapped on the conveying ends of the two conveying mechanisms 21 when the first conveying part 1 and the second conveying part 2 are connected, to complete the transfer of the tray 100. The structure is simple, the degree of human participation is low, the degree of automation is high, and the conveying efficiency of the tray 100 can be further ensured.
[0049] Exemplarily, the conveying mechanism 21 is preferably a belt conveying structure, and the upper surface of the carrier 11 and the bearing surface of the belt conveying structure are at the same horizontal plane, so as to ensure the stability of the first conveying part 1 and the second conveying part 2 when they are connected.
[0050] In this embodiment, the first conveying part 1 further includes a rack 12, which is arranged inside the shell and partially extends between the two conveying mechanisms 21. In actual application, the rack 12 is arranged along the second direction perpendicular to the first direction, and one end of the rack 12 is at the opening, and the other end is between the two conveying mechanisms 21. In this way, the moving path of the carrier 11 and the conveying path of the second conveying part 2 can intersect, so as to further ensure the stability of the tray 100 during the connection process.
[0051] In addition, the first conveying part 1 further includes a sliding guide rail 13 arranged between the rack 12 and the carrier 11. In this way, the stability of the carrier 11 can be ensured. The sliding guide rail 13 is preferably a multi-section guide rail in the existing structure, so as to save the occupied space of the first conveying part 1 inside the shell, thereby improving the space utilization rate inside the shell.
[0052] Furthermore, the first conveying unit 1 also includes two connectors 14, which are spaced apart at the bottom of the platform 11 along a first direction, and a sliding guide rail 13 is provided between each connector 14 and the frame 12. It can be understood that, under the action of the connectors 14, the two sliding guide rails 13 are distributed on both sides of the platform 11, thereby further ensuring the stability of the platform 11 during operation.
[0053] In some other feasible embodiments, the two connectors 14 are arranged in a "U" shape, that is, the two connectors 14 are integrally formed, thereby ensuring the connection strength of the connectors 14.
[0054] Furthermore, the first conveying unit 1 also includes a first limiting member 15, which is disposed on the connecting member 14; a second limiting member 16 is disposed on the frame 12, directly opposite the first limiting member 15, and the first limiting member 15 and the second limiting member 16 can abut against each other. It can be understood that as the platform 11 approaches the second conveying unit 2, the first limiting member 15 can approach the second limiting member 16 until they abut against each other. At this time, the platform 11 can stop under the action of the first limiting member 15 and the second limiting member 16, that is, the platform 11 is at its limit position. This arrangement can limit the maximum position of the platform 11, thereby avoiding collision between the platform 11 and the second conveying unit 2 and improving safety performance.
[0055] For example, the first limiting member 15 is sheet-shaped and its thickness direction is set along the second direction, and the second limiting member 16 is rod-shaped. In addition, the second limiting member 16 is provided with a PLC soft limit in the prior art to further ensure the safety performance of the material tray conveying device.
[0056] In this embodiment, the frame 12 is provided with extensions 17 on both sides along the first direction, and an alignment member 18 is provided on the top of the extension 17. The alignment member 18 is used to align the tray 100 on the platform 11. It can be understood that both the extensions 17 and the alignment members 18 are plate-shaped and can be assembled into an "L" shape. When the tray 100 is placed, the alignment members 18 on both sides can abut against the tray 100, thereby helping the operator to quickly position the tray 100 and further improve the transportation efficiency of the tray 100.
[0057] In addition, a limiting post 19 is provided at one end of the platform 11 away from the second conveying section 2. When the tray 100 is placed, the tray 100 can simultaneously abut against the limiting post 19 and the two alignment members 18, thereby further ensuring the posture of the tray 100 and further improving the transport efficiency of the tray 100.
[0058] In the embodiment, the tray conveying device further comprises a limiting mechanism 3 and an unlocking mechanism 4. The limiting mechanism 3 is arranged at the end of the carrier 11 close to the second conveying part 2, and is used to limit the tray 100 from being separated from the carrier 11. The unlocking mechanism 4 is arranged inside the housing, and is used to release the limiting mechanism 3 from limiting the tray 100 when the tray 100 is separated from the carrier 11. It can be understood that, during the feeding process, the carrier 11 is away from the unlocking mechanism 4, and at this time, the limiting mechanism 3 is in the limiting state, so as to avoid the tray 100 from being separated from the carrier 11 due to the forward movement of the tray 100 when the carrier 11 approaches the second conveying part 2. After the carrier 11 moves to the docking position of the second conveying part 2, the unlocking mechanism 4 can unlock the limiting mechanism 3, so as to facilitate the second conveying part 2 to receive the tray 100. During the discharging process, the carrier 11 is in the docking position and is in the unlocked state. After the docking is completed, the carrier 11 is away from the unlocking mechanism 4, so as to reset the unlocked state to the limiting state, so as to separate the tray 100 from the carrier 11 when the tray 100 is pulled out.
[0059] Specifically, the limiting mechanism 3 comprises a limiting piece 31 and a reset piece 32. The middle part of the limiting piece 31 is rotationally arranged at the bottom of the carrier 11, one end of the limiting piece 31 can extend above the carrier 11, and the other end can cooperate with the unlocking mechanism 4 to make one end of the limiting piece 31 rotate below the carrier 11. The reset piece 32 is arranged between the bottom of the carrier 11 and the limiting piece 31, so that one end of the limiting piece 31 can be kept above the carrier 11. It can be understood that, during the movement of the carrier 11 from the opening to the second conveying mechanism 21, the other end of the limiting piece 31 can cooperate with the unlocking mechanism 4, so that the limiting piece 31 can rotate, so that one end of the limiting piece 31 can rotate from above the carrier 11 to below the carrier 11, so that the limiting piece 31 can be switched from the limiting state to the unlocked state. When the carrier 11 is away from the second conveying part 2, the other end of the limiting piece 31 can be away from the unlocking mechanism 4, and under the action of the reset piece 32, the limiting piece 31 can be reset, so that the limiting piece 31 can be reset from the unlocked state to the limiting state. The reset piece 32 is preferably a reset spring.
[0060] Further, the unlocking mechanism 4 comprises an unlocking piece which is below the running path of the carrier 11 and has a slope 41 abutting against the other end of the limiting piece 31, the slope 41 gradually rises in the direction away from the opening. It can be understood that, in the feeding process, the other end of the limiting piece 31 can abut against the slope 41, so as to enable the limiting piece 31 to rotate, thereby enabling the limiting piece 31 to switch from the limiting state to the unlocking state, in the discharging process, the other end of the limiting piece 31 can be away from the slope 41, under the action of the reset piece 32, thereby enabling the limiting piece 31 to rotate reversely, thereby enabling the limiting piece 31 to switch from the unlocking state to the limiting state, in this way, the switching of the limiting piece 31 can be realized by a simple mechanical structure, compared with electrical control, the reliability is increased, and the safety performance of the tray conveying device can be improved.
[0061] In addition, the other end of the limiting piece 31 is provided with a rotating wheel 33, so as to reduce the abrasion between the limiting piece 31 and the slope 41.
[0062] In the embodiment, the tray conveying device further comprises a detection mechanism 5 which is arranged in the interior of the shell and is used for detecting whether the carrier 11 carries the tray 100. It can be understood that, in the discharging process, the detection mechanism 5 can feed back to the operator whether the carrier 11 carries the tray 100, thereby facilitating the operator to operate, so as to further improve the reliability of the tray conveying device, wherein the detection mechanism 5 is preferably a sensor such as a photoelectric sensor or a visual sensor, which will not be described here.
