DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1 The utility model provides the following technical solutions: a pallet docking mechanism, including a bracket 1 and a transfer platform 3; a transport space 2 for a transport vehicle to stay is provided between two separated brackets 1; two transfer platforms 3 are respectively arranged on the two brackets 1, and the two transfer platforms 3 are arranged along the entry and exit direction of the transport vehicle; the transfer platform 3 includes a plurality of rollers 4 rotatably connected to the bracket 1, and the axes of the rollers 4 are perpendicular to the length direction of the transfer platform 3.

[0025] As an optional implementation scheme of the utility model, when pallet A is sent out from the production line or sent into the production line from the docking mechanism, the rotation of the roller 4 can make the movement of pallet A more stable, avoiding the shaking of the stacked workpieces and affecting the subsequent loading and positioning, and the two separated brackets 1 also ensure that the transport vehicle can enter under pallet A to lift pallet A and then take it out of the docking mechanism. Therefore, the technical solution can be well applied in loading and unloading transportation and pallet A recycling.

[0026] like Figure 1 As shown, the transfer platform 3 also includes a mounting platform 5 , which is adjustably connected to the bracket 1 , and the rollers 4 are all arranged on the mounting platform 5 .

[0027] As an optional implementation scheme of the utility model, a waist-shaped hole is provided at the bottom of the mounting table 5, and the span of the two mounting tables 5 can be adjusted according to the width of the pallet A to accommodate pallets A of different specifications, and thus can be suitable for the transportation of various types of workpieces.

[0028] like Figure 1 As shown, a limiting mechanism 6 is provided at one end of the bracket 1 , and the limiting mechanism 6 can move between a blocking area directly above the transfer platform 3 and a non-blocking area below or outside the transfer platform 3 .

[0029] As an optional implementation scheme of the utility model, during the process of unloading and transferring, the pallet lifting mechanism close to the discharge end of the production line lifts pallet A to the same height as the upper surface of roller 4, and drives pallet A to move pallet A onto roller 4. The limiting mechanism 6 can block pallet A to prevent it from falling out, and can also be retracted when the transfer vehicle transports pallet A out.

[0030] like Figure 1As shown, the limiting mechanism 6 includes a lifting cylinder 61 arranged on the end surface of the bracket 1 and a limiting column 62 fixedly connected to the ejection end of the lifting cylinder 61 .

[0031] As an optional implementation scheme of the present invention, the use of a lifting cylinder 61 and a limiting column 62 can quickly respond to commands. Similarly, a rotation method can also be used to achieve the purpose of blocking the tray A. This is not specifically limited by the present invention.

[0032] like Figure 1 As shown, it also includes a limiting vertical plate 7 arranged along the length direction of the transfer platform 3. The limiting vertical plate 7 is adjustably connected to the bracket 1 and is located above the transfer platform 3.

[0033] As an optional implementation scheme of the utility model, two limiting plates 7 are used to limit the two ends of the pallet A to prevent the pallet A from deviating during its movement and affecting subsequent transportation and loading. In particular, when the AGV transporter's moving track in the transport space 2 is a fixed route, the accuracy of the positioning of the pallet A will affect the transporter's successful reception of the pallet A and its stability during the movement. Therefore, the setting of the limiting plates 7 is not only conducive to the loading positioning of the production line receiving the pallet A, but also conducive to the transportation and delivery of the transporter. Similarly, the limiting plates 7 are also provided with waist-shaped holes, and the limiting plates 7 are adjustable to accommodate pallets A of different specifications.

[0034] like Figure 2 As shown, it also includes a synchronization mechanism 8, which is arranged at the other end of the bracket 1 and includes a synchronization belt 81. One end of the synchronization belt 81 is connected to the shaft of the roller 4, and each roller 4 is driven by a belt or a chain.

[0035] As an optional implementation scheme of the utility model, the synchronous belt 81 can drive all the rollers 4 to rotate, so that the rollers 4 can drive the pallet A to move on the bracket 1, which is conducive to the movement of the pallet A between the bracket 1 and the production line, especially when a large number of workpieces are loaded on the pallet A or the pallet A is longer in front and back length and needs auxiliary drive.

[0036] like Figure 2-3 As shown, it also includes a synchronous rod 82 and a driven belt 83. The synchronous rod 82 is provided with a roller 84 that cooperates with the synchronous belt 81 and the driven belt 83. The two ends of the driven belt 83 are respectively connected to the roller 84 and the shaft of the drum 4. The synchronous belt 81 is rotatably connected to the roller 84.

[0037] As an optional implementation scheme of the utility model, the two driven belts 83 respectively drive the rollers 4 on the two brackets 1 through the synchronization rod 82, which not only keeps the rotation speeds of the rollers 4 on the two brackets 1 equal, but also completes the structural layout without occupying the transportation space 2.

[0038] Specifically, the other end of the synchronous belt 81 is connected to the shaft rod of the conveying chain of the pallet lifting mechanism.

[0039] As an optional implementation scheme of the utility model, the driving speed of the pallet A at the discharging or feeding end of the production line is made completely consistent with the moving speed of the pallet A on the bracket 1, further ensuring the stability of the docking of the pallet A.

[0040] Specifically, a motor is further provided at the other end of the synchronous belt 81 .

[0041] As an optional implementation scheme of the present invention, the synchronization rod 82 may also be driven by a motor.

[0042] like Figure 2-3 As shown, it also includes an alignment mechanism 9, including a telescopic vertical plate 91 and a vertical rod 92. The two telescopic vertical plates 91 are both arranged on the side of the bracket 1 close to the synchronization mechanism 8, and the vertical rods 92 are both rotatably connected to the side of the telescopic vertical plates 91 facing the synchronization mechanism 8.

[0043] As an optional implementation scheme of the present invention, when pallet A enters or moves out from above the bracket 1, the two ends of pallet A are pressurized by the telescopic vertical plates 91, and pallet A moves between the two rows of vertical rods 92 to keep the moving route of pallet A unchanged, which is beneficial to the positioning of the workpiece when it is grasped by the production line robot and the positioning of pallet A on the bracket 1.

[0044] In this technical solution, the telescopic vertical plate 91 can be driven by a cylinder.

[0045] The working principle and use process of the utility model are as follows: when unloading, pallet A is driven to the side of bracket 1 by the pallet lifting mechanism beside the production line, and is at the same height as the upper surface of roller 4, and is driven to roller 4 by the conveying chain on the lifting mechanism, and the AGV transporter is called; the AGV transporter enters the transport space 2, the lifting plate of the AGV is lifted upward and lifts pallet A so that pallet A and the limit mechanism 6 move to the non-blocking area, and the AGV transporter moves out of the transport space 2;

[0046] When loading materials, the AGV transporter carries pallet A into the front of the handling space 2, the limit mechanism 6 moves to the non-blocking area, the lifting plate of the transporter rises and enters the handling space 2, and at the same time, pallet A also enters the area above the bracket 1, the lifting plate descends, and pallet A is placed on the roller 4, which is driven to rotate by the synchronous belt 81, so that pallet A moves to the side of the production line; before pallet A moves out from above the bracket 1, the alignment mechanism 9 presses the two ends of pallet A through two rows of vertical sticks 92, so that pallet A maintains the moving path unchanged, ensuring the correct loading positioning of the subsequent production line.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
