[0038] Please also read Figure 1 The automatic palletizing device provided in this embodiment includes a conveyor line 100, a fixture 200, a tooling vehicle 300 and a robot 400. The conveyor line 100 is used to convey parts 500 and automatically block and lift the parts 500 arriving at the corresponding workstation 11. The fixture 200 is used to absorb the parts 500 on the workstation 11. The tooling vehicle 300 is used to receive the parts 500 released by the fixture 200. The robot 400 drives the fixture 200 to move to simultaneously absorb and palletize multiple parts 500 to the tooling vehicle 300, and finally realizes the automatic palletizing and loading production of the parts 500, replacing the manual handling operation.

[0039] The conveyor line 100 includes a support assembly, a transmission assembly and a station assembly. The conveyor line 100 can realize the conveying, blocking and lifting of the parts 500.

[0040] The support assembly is mainly used to fix and support the transmission assembly and the station assembly. The support assembly includes a longitudinal support frame 12 and a transverse support frame 13. The number of longitudinal support frames 12 is two or more, and the number of transverse support frames 13 can be one. The transverse support frame 13 is fixed to the top of the longitudinal support frame 12. The transverse support frame 13 includes a first support rod 131 and a second support rod 132 arranged side by side, and a hollow area is provided between the first support rod 131 and the second support rod 132.

[0041] The conveying assembly is used to convey the parts 500. The conveying assembly is arranged between the first support rod 131 and the second support rod 132. The conveying assembly includes a first conveyor belt 141 and a second conveyor belt 142 arranged side by side. The first conveyor belt 141 is arranged adjacent to the first support rod 131, and the second conveyor belt 142 is arranged adjacent to the second support rod 132. It can be understood that the width of the gap between the first support rod 131 and the second support rod 132 is much larger than the sum of the widths of the first conveyor belt 141 and the second conveyor belt 142, and there is still a hollow area between the first conveyor belt 141 and the second conveyor belt 142.

[0042] The station assembly is mainly used to block and lift the part 500. The station assembly includes a plurality of stations 11 arranged between the first conveyor belt 141 and the second conveyor belt 142, that is, the plurality of stations 11 are arranged in the hollow area between the first support rod 131 and the second support rod 132, and will not contact the first conveyor belt 141 and the second conveyor belt 142, thereby avoiding the problem of interference between the components in the station 11 and the conveyor belt. The plurality of stations 11 are located at the end of the conveyor line 100 and are arranged at intervals along the conveying direction, and each station 11 includes a blocking portion 112 and a lifting portion 113 arranged adjacently. Among them, the blocking portion 112 is used to block and position the part 500, and the blocking portion 112 includes a baffle 1121 and a first cylinder 1122, the first cylinder 1122 is connected to the baffle 1121, and the first cylinder 1122 drives the baffle 1121 to move to block and position the part 500 arriving at the corresponding station 11. The lifting part 113 is used to lift and position the part 500. The lifting part 113 includes a supporting plate 1131 and a second cylinder 1132. The second cylinder 1132 is connected to the supporting plate 1131. The second cylinder 1132 drives the supporting plate 1131 to move so as to lift and position the part 500 that arrives at the corresponding workstation 11.

[0043] The conveyor line 100 also includes a transverse correction mechanism for transversely correcting the part 500. The transverse correction mechanism includes at least a first correction member 151, a second correction member 152 and a third cylinder 153, wherein the first correction member 151 is movably arranged on one side of the first conveyor belt 141, the second correction member 152 is movably arranged on one side of the second conveyor belt 142, the third cylinder 153 is arranged between the first conveyor belt 141 and the second conveyor belt 142, and is connected to the first correction member 151 and the second correction member 152 respectively, and the third cylinder 153 drives the first correction member 151 and the second correction member 152 to approach each other to perform transverse correction on the part 500 arriving at the corresponding station 11.

[0044] In this embodiment, a corresponding transverse correction mechanism can be configured for each workstation 11, or all workstations 11 can share a transverse correction mechanism, the latter of which can simplify the structure and workflow of the device. Further, if there are a large number of workstations 11 on the conveyor line 100, and all workstations 11 share a transverse correction mechanism, at this time, the first correction member 151 and the second correction member 152 are relatively long. In order to ensure that the first correction member 151 and the second correction member 152 can move smoothly, the transverse correction mechanism can also include a plurality of first fixed rods 154 and a plurality of second fixed rods 155, the first fixed rod 154 is installed on the first support rod 131, and the second fixed rod 155 is installed on the second support rod 132. In other words, the first fixed rod 154 is fixedly arranged on one side of the first conveyor belt 141, and the second fixed rod 155 is fixedly arranged on one side of the second conveyor belt 142. The specific number of the first fixed rod 154 and the second fixed rod 155 can be reasonably designed according to the length of the first correction member 151 and the second correction member 152. The plurality of first fixing rods 154 are all connected to the first correction member 151 to support the first correction member 151 , and the plurality of second fixing rods 155 are all connected to the second correction member 152 to support the second correction member 152 .

[0045] The present embodiment does not limit the specific structure of the first correction member 151 and the second correction member 152. The first correction member 151 and the second correction member 152 may be configured to adopt a rod-shaped structure, a plate-shaped structure or other types of structures. As an example, both correction members are composed of a bottom plate and a side. The first correction member 151 includes a first bottom plate 1511 and a first side plate 1512 perpendicular to the first bottom plate 1511. The first bottom plate 1511 is connected to the first fixing rod 154. The first side plate 1512 is used to abut against the part 500. Similarly, the second correction member 152 includes a second bottom plate 1521 and a second side plate 1522 perpendicular to the second bottom plate 1521. The second bottom plate 1521 is connected to the second fixing rod 155. The second side plate 1522 is used to abut against the part 500.

[0046] For ease of understanding, the following Figures 2 to 7 A more detailed transmission line is introduced.

[0047] like Figure 2As shown, the transmission line includes two longitudinal support frames 12, a transverse support frame 13, two conveyor belts, four workstations 11, and a transverse correction mechanism. The two longitudinal support frames 12 are arranged at intervals, and the transverse support frame 13 is installed at the top of the two longitudinal support frames 12. The transverse support frame 13 includes a first support rod 131 and a second support rod 132 arranged side by side, and a hollow area is provided between the first support rod 131 and the second support rod 132. The two conveyor belts are arranged between the first support rod 131 and the second support rod 132. The two conveyor belts include a first conveyor belt 141 and a second conveyor belt 142 arranged side by side. The first conveyor belt 141 is arranged adjacent to the first support rod 131, and the second conveyor belt 142 is arranged adjacent to the second support rod 132. The four workstations 11 are arranged between the first conveyor belt 141 and the second conveyor belt 142, and the four workstations 11 are arranged in sequence along the transmission direction.

[0048] like Figure 2 , Figure 3 and Figure 4 As shown, each station 11 includes a blocking portion 112 and a lifting portion 113. The blocking portion 112 includes a baffle 1121 and a first cylinder 1122. The first cylinder 1122 is located below the baffle 1121 and connected to the baffle 1121. The first cylinder 1122 drives the baffle 1121 to move in the up and down directions. After the part 500 on the transmission line arrives at the corresponding station 11, the first cylinder 1122 drives the baffle 1121 to move upward so that the baffle 1121 abuts against the side of the part 500, thereby blocking the part 500 from moving forward, thereby achieving blocking and positioning of the part 500. The lifting portion 113 includes a bearing plate 1131 and a second cylinder 1132. The second cylinder 1132 is located below the bearing plate 1131 and connected to the bearing plate 1131. The second cylinder 1132 drives the bearing plate 1131 to move in the up and down directions. After the part 500 on the transmission reaches the corresponding workstation 11 and completes the blocking positioning, the second cylinder 1132 drives the carrying plate 1131 to move upward to lift the part 500, so that the part 500 is separated from the two conveyor belts, thereby preventing the part 500 from wearing the conveyor belt of the conveyor line 100 and achieving the lifting positioning of the part 500.

[0049] like Figure 2 , Figures 4 to 7As shown, the lateral correction mechanism includes two correction parts, four fixed rods and a third cylinder 153. The four fixed rods include two first fixed rods 154 and two second fixed rods 155. The two first fixed rods 154 are installed on the first support rod 131, and the two second fixed rods 155 are installed on the second support rod 132. The two correction parts are the first correction part 151 and the second correction part 152. The first correction part 151 includes a first bottom plate 1511 and a first side plate 1512 which are perpendicular to each other. The first bottom plate 1511 is connected to one side of the third cylinder 153 through a connecting bracket, and the two ends of the first bottom plate 1511 are respectively connected to the two first fixed rods 154, and the first side plate 1512 is used to abut against the side of the part 500. Similarly, the second correction member 152 includes a second bottom plate 1521 and a second side plate 1522 which are perpendicular to each other. The second bottom plate 1521 is connected to the other side of the third cylinder 153 through a connecting bracket, and the two ends of the second bottom plate 1521 are respectively connected to two second fixing rods 155. The second side plate 1522 is used to abut against the side of the part 500. The third cylinder 153 drives the first correction member 151 and the second correction member 152 to move closer to or away from each other. After the part 500 on the transmission line arrives at the corresponding station 11, the third cylinder 153 drives the first correction member 151 and the second correction member 152 to move closer to each other so that the first side plate 1512 and the second side plate 1522 abut against the side of the part 500, thereby realizing the lateral correction of the four parts 500.

[0050] It can be understood that the lateral correction, blocking positioning and lifting positioning of the four parts 500 are achieved so as to be supplied to the clamp 200 for suction.

[0051] The fixture 200 includes a plurality of picking units 22 , the number of the picking units 22 is the same as the number of the stations 11 of the transmission line, and the intervals between the picking units 22 are the same as the intervals between the stations 11 .

[0052] See also Figure 8 The clamp 200 includes a connecting rod 21 and four picking units 22 spaced apart on the connecting rod 21 , each picking unit 22 includes a picking rod 221 and a sponge suction cup 222 , one end of the picking rod 221 is connected to the connecting rod 21 , and the sponge suction cup 222 is installed on the other end of the picking rod 221 .

[0053] The tooling vehicle 300 includes a plurality of carrying units 31, the number of the carrying units 31 is the same as the number of the picking units 22 of the fixture 200, and the intervals between the carrying units 31 are the same as the intervals between the picking units 22. The plurality of carrying units 31 are stacked from bottom to top.

[0054] See also Fig.10The tooling vehicle 300 includes four load-bearing units 31, each of which is a cantilever bracket. In addition, a protective plate (not shown in the figure) is provided on each layer of the cantilever bracket to protect the parts 500. After the automatic stacking of the parts 500 is realized, a plurality of parts 500 are stacked on each layer of the cantilever bracket along its own extension direction.

[0055] See also Fig. 9 , Fig.10 , the robot 400 is connected to the fixture 200, and the robot 400 drives the fixture 200 to move. It can be understood that the robot 400 can drive the fixture 200 to translate and rotate, so that when the fixture 200 absorbs the part 500, the picking unit 22 of the fixture 200 can be set corresponding to the station 11 of the conveyor line 100, and when the fixture 200 releases the part 500, the picking unit 22 of the fixture 200 can be set corresponding to the carrying unit 31 of the tooling vehicle 300. The robot 400 drives the fixture 200 to move to realize the simultaneous absorption and simultaneous stacking of multiple parts 500 on the tooling vehicle 300, and realize the automatic stacking and loading production of parts 500.

[0056] See also Figure 1 , the conveyor line 100 is arranged in a horizontal direction, and four workstations 11 are arranged on the conveyor line 100. Four cantilever brackets on the tooling vehicle 300 are stacked from bottom to top, and four sponge suction cups 222 are arranged on the fixture 200. If the fixture 200 absorbs the part 500, the fixture 200 is installed on the robot 400 and is driven by the robot 400 to move itself. Under the drive of the robot 400, the four sponge suction cups 222 on the fixture 200 correspond to the four workstations 11 on the conveyor line 100 one by one, and the fixture 200 can absorb four parts 500 at the same time. If the fixture 200 releases the part 500, the fixture 200 is driven by the robot 400 to rotate the fixture 200 by a certain angle (for example, 90 degrees), so that the four parts 500 absorbed by the fixture 200 correspond to the four cantilever brackets of the tooling vehicle 300 one by one, and the fixture 200 can release the four parts 500 at the same time. Finally, each part 500 is snap-fitted onto the corresponding cantilever bracket.

[0057] It is understandable that the number of parts 500 to be transported each time is usually determined in combination with the size of the parts 500, the arm span of the robot 400, and the structure of the tooling vehicle 300. Fig.11As shown, part 500 is a wall-mounted panel. For wall-mounted panels, four pieces are optimal. The storage time of three pieces is short, which cannot meet the robot 400's suction and loading operation for one cycle, thus causing material blockage. Five pieces or more occupy a large space of the line, and the robot 400's trajectory cannot meet it, and the five-layer structure of the tooling vehicle 300 is too high and exceeds the standard. Taking four pieces as an example, first, a four-layer structure of the tooling vehicle 300 is designed according to the size structure of the wall-mounted panel, and the part 500 can be placed vertically on each layer of the cantilever bracket of the tooling vehicle 300. Then, according to the distance between each layer of the tooling vehicle 300, a clamp 200 of appropriate size is designed. Considering that the surface of the wall-mounted panel has many ribs and is uneven, a sponge suction cup 222 is used for adsorption. The clamp 200 includes four picking units 22, each of which includes a picking rod 221 and a sponge suction cup 222 installed at the end of the picking rod 221. The clamp 200 can realize the simultaneous absorption of four parts 500. Finally, according to the size intervals of the four picking units 22 of the fixture 200, a conveyor line 100 with four workstations 11 is designed accordingly. The four workstations 11 are correspondingly designed with four blocking cylinders and four lifting cylinders. The conveyor line 100 is also provided with a lateral correction mechanism to achieve automatic blocking, lifting positioning and lateral position correction of the four parts 500. Finally, in conjunction with the action of the robot 400, the four parts 500 are simultaneously sucked and stacked on the tooling vehicle 300.

[0058] The working principle of the automatic palletizing device is as follows: the head end of the conveyor line 100 is set at the discharge position, and the conveyor line 100 is used to carry and transport the parts 500 from the discharge position. The end of the conveyor line 100 is sequentially provided with four stations 11 and a partition part along the conveying direction. When a part 500 arrives at the corresponding station 11, the first cylinder 1122 of the station 11 drives the baffle 1121 to move upward to block and position the part 500, and the second cylinder 1132 of the station 11 drives the carrier plate 1131 to move upward to lift and position the part 500. While lifting and positioning the previous station 11, the first cylinder 1122 of the next station 11 drives the baffle 1121 to move upward to block and position the part 500. After the blocking and lifting positioning of the four parts 500 are realized in sequence, the fourth cylinder 162 of the partition part finally drives the partition member 161 to rise to realize the partition of the part 500. At the same time, since the correction parts are installed on both sides of the conveyor line 100, the lateral correction of the four parts 500 after the longitudinal positioning is realized under the drive of the third cylinder 153, and finally the lateral correction, blocking positioning, and lifting positioning of the four parts 500 are realized to supply the fixture 200 installed on the robot 400 for absorption. After the four parts 500 are absorbed, all cylinders are reset to position the next group of parts 500, and finally the four parts 500 are absorbed and stacked on the tooling vehicle 300 at the same time in coordination with the action of the robot 400. This device effectively solves the problem of difficulty in realizing automatic stacking of robots due to the fast production cycle of continuous die stamping, completely replaces manual handling operations, improves the automation level of sheet metal workshops, and makes good technical precipitation for the application of automatic stacking of continuous dies in the industry.
