DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] A pallet automatic loading mechanism comprises: a shelf 1, on which a first storage area and a second storage area are arranged at intervals, a plurality of first placement positions 2 are arranged at intervals in the vertical direction in the first storage area, the first placement position 2 is used to place a pallet 4 loaded with workpieces, a plurality of second placement positions 3 are arranged at intervals in the vertical direction in the second storage area, the second placement position 3 is used to place an empty pallet 4; a third placement position 5, which is movably arranged on one side of the shelf 1 and can be aligned with any one of the first placement positions 2 or the second placement; a blocking member 6, the pallet 4 loaded with workpieces has a first moving path when entering the first placement position 2, and a second moving path when moving out of the first placement position 2, the blocking member 6 is movably arranged on the first moving path, and is used to provide a limit for the pallet 4 loaded with workpieces; a material picking member 7, which is movably arranged below the third placement position 5; wherein the pallet 4 loaded with workpieces can be moved to the third placement position 5 due to the blocking member 6 being away from the first moving path and driven by the material picking member 7; the empty pallet 4 on the third placement position 5 can enter the second placement position 3 under the drive of the material picking member 7.

[0028] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 1 to 4 As shown, the shelf 1 adopts a hollow cube structure and is equipped with a partition inside. The partition divides the inside of the shelf 1 into two independent storage areas - a first storage area and a second storage area. In the first storage area, seven first placement positions 2 are arranged at equal intervals along the vertical axis, and in the second storage area, seven second placement positions 3 are arranged at equal intervals along the vertical direction. During normal operation, the material picker 7 takes the pallet 4 filled with workpieces from the first placement position 2 one by one in sequence and transfers it to the preset third placement position 5. When the workpieces on the pallet 4 are completely taken away, the material picker 7 will move the empty pallet 4 from the third placement position 5 to the second placement position 3 for storage. Thereafter, continue to move the fully loaded pallet 4 on the first placement position 2 to the third placement position 5, and repeat the above steps until all workpieces of the same batch are processed.

[0029] When replenishing the tray 4 at the first placement position 2, the new tray 4 follows Figure 1 In addition, a blocking member 6 is provided to ensure that the tray 4 does not accidentally slide out of the first placement position 2 during the movement. The blocking member 6 is designed to be movable, and when the material taking member 7 needs to take out the tray 4, the restriction on the tray 4 can be automatically released so that the material taking operation can proceed smoothly.

[0030] In this solution, a first storage area and a second storage area are set on the shelf 1 for placing fully loaded pallets 4 and empty pallets 4 respectively, and a material picking component 7 is movably set on one side of the shelf 1 to take out the fully loaded pallets 4 in the first storage area and transport the empty pallets 4 to the second storage area, thereby realizing the automatic loading process of the pallets 4, which reduces the work intensity of the pallet 4 transportation and can ensure that the loading speed of the pallets 4 meets the working rhythm of the assembly line.

[0031] In this solution, based on the above technical features, the following optimizations are made to the structures of the tray 4 and the material taking member 7:

[0032] A material taking recess 8 is provided at the bottom of each tray 4 , and a material taking protrusion 9 is provided on the material taking piece 7 . The material taking protrusion 9 is movably inserted into the material taking recess 8 to fix the tray 4 on the material taking piece 7 , thereby realizing the transfer operation of the tray 4 by the material taking piece 7 .

[0033] In addition, the first placement position 2 , the second placement position 3 and the third placement position 5 all include support blocks 10 resting on both sides of the bottom of the tray 4 , and there is a gap between the two support blocks 10 to expose the material removal recess 8 to the outside, so that the material removal member 7 can remove the tray 4 .

[0034] In this solution, two support blocks 10 are used to form the first placement position 2, the second placement position 3 and the third placement position 5. On the premise of providing support for the tray 4, when the material picking member 7 drives the tray 4 to move along the first moving path or the second moving path, the gap between the two support blocks 10 is used to prevent interference between the support blocks 10 and the tray 4, thereby allowing the tray 4 to move to any placement position.

[0035] In addition, in the present solution, a first driving member 11 is erected on the top of the shelf 1, and a driving rod 12 is provided at the output end of the first driving member 11, which is movably inserted on the shelf 1 and located between the first placement position 2 and the second placement position 3. The blocking member 6 is connected to the driving rod 12 to drive the blocking member 6 to move.

[0036] When the fully loaded pallet 4 is placed into the first storage area, the first driving member 11 moves the blocking member 6 to the first moving path by driving the driving rod 12 to move, thereby limiting the placement of the pallet 4. When the material picking member 7 takes out the pallet 4 in the first storage area, the first driving member 11 drives the driving rod 12 to move in the opposite direction, driving the blocking member 6 to reset, thereby releasing the restriction on the pallet 4. Preferably, the first driving member 11 is a cylinder.

[0037] In addition, in the present solution, a second driving member 13 is horizontally arranged on the third placement position 5, a positioning member 14 is arranged at the output end of the second driving member 13, a positioning groove 15 is arranged on one side of each tray 4, and the positioning member 14 is movably inserted in the positioning groove 15, so as to fix the tray 4 at a preset position on the third placement position 5.

[0038] After the material picking member 7 moves the tray 4 to the third tray 4, the second driving member 13 drives the positioning member 14 to be inserted into the positioning groove 15, which can not only position the tray 4 but also fix the tray 4. Preferably, the second driving member 13 is a cylinder and the positioning member 14 is a roller or a bearing.

[0039] Finally, the present scheme also includes: a third driving member 16, which is vertically arranged on the side of the shelf 1; a fourth driving member 17, which is horizontally arranged at the output end of the third driving member 16; a moving seat 18, which is connected to the output end of the fourth driving member 17; a fifth driving member 19, which is horizontally connected to the moving seat 18, and the output shaft of the fifth driving member 19 is vertically arranged to the output shaft of the fourth driving member 17, and the material picking member 7 is movably arranged on the moving seat 18 and connected to the output end of the fifth driving member 19; a sensor 20, a sensor 20 is arranged on one side of the first placement position 2, the second placement position 3 and the third placement position 5, and the sensor 20 is used to sense whether there is a tray 4 placed on the first placement position 2, the second placement position 3 and the third placement position 5.

[0040] Among them, the third driving member 16 and the fourth driving member 17 are preferably linear guide rails. The third driving member 16 and the fourth driving member 17 realize the vertical and horizontal movement of the third placement position 5 and the material picking member 7 through the moving seat 18. The fifth driving member 19 is preferably a cylinder, which is used to drive the driving member to move in the direction of the activity or away from the shelf 1.
