The first positioning column and the second positioning column are arranged along a first direction. When loading, the first positioning column reaches the positioning device 100 earlier than the second positioning column. When the positioning device 100 is applied to the processing equipment, and the loading device conveys the workpiece to be processed to the position of the positioning device 100, the positioning mechanism 20 is in the first position relative to the mounting plate 10. At this time, the first positioning column of the workpiece to be processed slides along the limiting groove 21 until it abuts against the side wall of the limiting groove 21. At this time, through the cooperation between the first positioning column and the limiting groove 21, the workpiece to be processed is The workpiece is positioned along the first direction; after positioning, the positioning mechanism 20 moves relative to the mounting plate 10 along the third direction so that the positioning mechanism 20 is in the second position, thereby lifting the workpiece to be processed along the third direction, so that the overhead crane assembly located above the positioning mechanism 20 can clamp one side of the workpiece to be processed and transport it to the processing machine; then the positioning mechanism 20 returns to the first position and moves to the third position so that the overhead crane assembly continues to transport the workpiece to be processed toward the processing machine, and the second positioning column slides in the second through groove 22 and the first through groove 11 in turn, and passes through the positioning device 100 smoothly.

The first cylinder 31 is used to drive the first piston rod 32 to move along the third direction, thereby driving the first mounting portion 33 and the positioning mechanism 20 to move along the third direction.

[0060] It should be noted that the first driving mechanism 30 is disposed on the side of the positioning mechanism 20 facing away from the sixth surface 25.

[0061] It should be noted that the first mounting portion 33 is connected to the positioning mechanism 20. It can be that the first mounting portion 33 is directly connected to the positioning mechanism 20. It can also be that there are other components between the first mounting portion 33 and the positioning mechanism 20, and the first mounting portion 33 is connected to the positioning mechanism 20 through other components.

[0062] It should be noted that the positioning mechanism 20 is located on the side of the first mounting portion 33 facing away from the first cylinder 31.

[0063] It can be understood that the first piston rod 32 extends along the third direction.

[0064] It can be understood that the first cylinder 31, the first piston rod 32, the first mounting portion 33, and the positioning mechanism 20 are arranged in sequence along the third direction.

[0065] In this embodiment, by providing the first driving mechanism 30, the positioning mechanism 20 can be driven to move along the third direction relative to the mounting plate 10. Thus, after the positioning of the positioning mechanism 20 is completed, the workpiece to be processed can be lifted upward along the third direction, so that the overhead crane assembly can clamp the workpiece to be processed. In addition, by using the cooperation of the first cylinder 31, the first piston rod 32, and the first mounting portion 33 to drive the positioning mechanism 20 to move along the third direction, the structure is simple, the volume is small, and the position of the positioning mechanism 20 in the third direction can be adjusted more accurately.

The second driving mechanism 40 is located between the positioning mechanism 20 and the first driving mechanism 30 and is configured to drive the positioning mechanism 20 to move relative to the mounting plate 10 in a second direction. The second driving mechanism 40 includes a second cylinder 41, a second piston rod 42, and a second mounting portion 43. The second cylinder 41 is connected to the first mounting portion 33.

The second cylinder 41 is configured to drive the second piston rod 42 to move in the second direction, thereby driving the second mounting portion 43 and the positioning mechanism 20 to move in the second direction.

[0067] It should be noted that the first driving mechanism 30, the second driving mechanism 40, and the positioning mechanism 20 are arranged in sequence in a third direction.

[0068] It should be noted that the positioning mechanism 20 is located on a side of the second mounting portion 43 away from the second cylinder 41.

Part of the second mounting portion 43 is located on a side of the second piston rod 42 away from the second cylinder 41, and part of the second mounting portion 43 is located on a side of the second cylinder 41 away from the first driving mechanism 30.

[0071] In this embodiment, by providing the second driving mechanism 40, the positioning mechanism 20 can be driven to move relative to the mounting plate 10 in the second direction. Thus, after the positioning mechanism 20 finishes positioning and the overhead crane assembly clamps the workpiece to be processed and conveys it to the processing machine, the positioning mechanism 20 can be moved to a third position in the second direction, so that the first through groove 11 and the second through groove 22 are correspondingly arranged. Thereby, the second positioning post of the workpiece to be processed can smoothly pass through the second through groove 22 and the first through groove 11, so as to avoid interference of the positioning device 100 with the workpiece to be processed and affect the loading of the workpiece to be processed. In addition, the cooperation of the second cylinder 41, the second piston rod 42, and the second mounting portion 43 is adopted to drive the positioning mechanism 20 to move in the second direction, with a simple structure, a small volume, and more accurate adjustment of the position of the positioning mechanism 20 in the second direction.

The positioning mechanism 20 is located on a side of the second mounting sub-portion 432 facing away from the second cylinder 41. In this way, not only can the positioning mechanism 20 be driven to move back and forth along the second direction, but also the dimension of the second driving mechanism 40 and the positioning mechanism 20 along the second direction after assembly can be reduced, so that the assembly of the first driving mechanism 30, the second driving mechanism 40, and the positioning mechanism 20 is more compact and the volume is more miniaturized.

[0076] Please refer to again Figure 5 and Figure 6 , in some embodiments, the positioning device 100 further includes a support member 50. The support member 50 includes a first support portion 51, a second support portion 52, and a third support portion 53 that are sequentially bent and connected. The first support portion 51 extends along the second direction and is located between the first driving mechanism 30 and the second driving mechanism 40. The second support portion 52 and the third support are both located on a side of the first support portion 51 facing away from the first driving mechanism 30. The first support portion 51, the second support portion 52, and the positioning mechanism 20 cooperate to support the workpiece to be processed.

[0077] Understandably, the first support portion 51 is located between the first mounting portion 33 and the second cylinder 41 and is respectively connected to the first mounting portion 33 and the second cylinder 41. It is also understandable that the first mounting portion 33, the first support portion 51, and the second cylinder 41 are arranged in sequence along the third direction.

[0078] Understandably, along the second direction, the second support portion 52 and the third support portion 53 are respectively located on opposite sides of the positioning mechanism 20. In other words, along the second direction, the second support portion 52, the first support portion 51, and the third support portion 53 are arranged in sequence.

[0079] Understandably, both the second support portion 52 and the third support portion 53 extend along the third direction.

[0080] Optionally, the surface of the second support portion 52 facing away from the first support portion 51, the surface of the third support portion 53 facing away from the second support portion 52, and the sixth surface 25 are flush or coplanar.

[0081] In this embodiment, the positioning device 100 further includes a support member 50, and the support member 50 includes a first support portion 51, a second support portion 52, and a third support portion 53 that are sequentially bent and connected; when the feeding device transports the workpiece to be processed to the position of the positioning device 100, the first support portion 51, the positioning mechanism 20, and the second support portion 52 cooperate to better support the workpiece to be processed, avoiding dislocation due to unstable support of the workpiece to be processed and affecting the positioning effect of the positioning mechanism 20 on the workpiece to be processed.

[0082] Please refer to Figure 9 , in some embodiments, the positioning mechanism 20 includes a first positioning member 26 and a second positioning member 27. The first positioning member 26 has the limiting groove 21 and the second through groove 22; the second positioning member 27 is rotatably connected to the first positioning member 26, the second positioning member 27 penetrates the side wall of the limiting groove 21, and can protrude telescopically from the limiting groove 21; the workpiece to be processed includes a positioning post (the positioning post here is the first positioning post above, not shown in the figure). When the positioning post of the workpiece to be processed slides along the limiting groove 21 to the second positioning member 27, the second positioning member 27 is pushed to retract; when the positioning post moves to abut against the side wall of the limiting groove 21 close to the mounting plate 10, the second positioning member 27 protrudes from the limiting groove 21, and the first positioning member 26 and the second positioning member 27 cooperate to position the positioning post, thereby realizing the positioning of the workpiece to be processed.

[0083] Understandably, the positioning mechanism 20 further includes a rotating shaft 28. The rotating shaft 28 is disposed on the side of the first positioning member 26 away from the first driving mechanism 30. The second positioning member 27 is sleeved on the outer periphery of the rotating shaft 28 and can rotate relative to the first positioning member 26 around the rotating shaft 28.

[0084] Optionally, the first positioning member 26 has a sunk groove 261. The sunk groove 261 penetrates the sixth surface 25 and the side wall of the limiting groove 21, so that the sunk groove 261 communicates with the limiting groove 21. The second positioning member 27 is located in the sunk groove 261 and partially protrudes telescopically from the limiting groove 21.

[0085] Understandably, there is a gap between the part of the second positioning member 27 protruding from the limiting groove 21 and the side wall of the limiting groove 21 close to the mounting plate 10.

[0086] Understandably, when the positioning post of the workpiece to be processed moves in the limit groove 21 until the positioning post abuts against the second positioning member 27, and the workpiece to be processed is continuously moved in the direction close to the processing machine table, the positioning post pushes the second positioning member 27 to retract into the sunk groove 261. When the positioning post moves to be close to the side wall of the limit groove 21 close to the mounting plate 10, at this time, the positioning post is separated from the second positioning member 27, and the second positioning member 27 protrudes out of the limit groove 21 again and pushes the positioning post towards the side wall direction close to the limit groove 21. Through the cooperation of the first positioning member 26 and the second positioning member 27, the positioning post is positioned, and further, the workpiece to be processed is positioned in the first direction and the second direction.

[0087] In this embodiment, through the cooperation of the first positioning member 26 and the second positioning member 27, the position of the workpiece to be processed in the first direction and the second direction can be better positioned, thereby improving the processing accuracy of the workpiece to be processed. The structure is simple and easy to implement.

[0088] In some embodiments, the positioning mechanism 20 further includes an elastic member 29. The elastic member 29 is located between the first positioning member 26 and the second positioning member 27. A part of the elastic member 29 penetrates through the first positioning member 26 and abuts against the first positioning member 26, and another part of the elastic member 29 penetrates through the second positioning member 27 and abuts against the second positioning member 27. When the positioning post of the workpiece to be processed slides along the limit groove 21 to the second positioning member 27, it pushes the second positioning member 27 to compress the elastic member 29 and thus retract. When the positioning post moves to abut against the side wall of the limit groove 21 close to the mounting plate 10, the elastic member 29 pushes the second positioning member 27 to protrude out of the limit groove 21 again, and the first positioning member 26 and the second positioning member 27 cooperate to position the positioning post, thereby realizing the positioning of the workpiece to be processed.

[0089] Optionally, the elastic member 29 and the rotating shaft 28 are arranged at intervals.

[0090] Optionally, the surface of the first positioning member 26 facing the second positioning member 27 has a first groove (not shown in the figure), and one side of the second positioning member 27 facing the first positioning member 26 has a second groove (not shown in the figure). A part of the elastic member 29 is located in the first groove, a part is located between the first positioning member 26 and the second positioning member 27, and another part is located in the second groove.

[0091] When the positioning column of the workpiece to be processed slides along the limiting groove 21 to abut against the second positioning member 27, and when the workpiece to be processed continues to move along the first direction toward the mounting plate 10, the workpiece to be processed pushes the second positioning member 27 to compress the elastic member 29, so that the part of the second positioning member 27 protruding from the limiting groove 21 retracts into the recessed groove 261. When the positioning column moves to abut against the side wall of the limiting groove 21 close to the mounting plate 10, the elastic member 29 pushes the second positioning member 27 to protrude from the limiting groove 21 again. The first positioning member 26 and the second positioning member 27 clamp the positioning column from both ends respectively to position the positioning column, thereby realizing the positioning of the workpiece to be processed.

[0092] In this embodiment, the cooperation of the first positioning member 26, the second positioning member 27 and the elastic member 29 can better position the workpiece to be processed at a preset position, so that when the workpiece to be processed is transported to the processing machine, its position along the first direction and the second direction (i.e., the length direction and width direction of the workpiece to be processed) is accurate, so that the workpiece to be processed can be processed more accurately and the processing accuracy of the workpiece to be processed is improved.

[0093] In some embodiments, the positioning mechanism 20 further includes a sensor 29a, which is disposed on the first positioning member 26 and close to the second positioning member 27, and is used to detect a signal of the second positioning member 27, so as to determine whether the workpiece to be processed is accurately positioned according to the signal.

[0094] Optionally, the sensor 29a can be but is not limited to a slot-type photoelectric sensor. When the positioning column of the workpiece to be processed is inserted into the side of the limiting groove 21 close to the mounting plate 10, the part of the second positioning member 27 away from the side of the limiting groove 21 penetrates into the groove of the slot-type photoelectric sensor, so that a signal can be detected. Then, based on the signal detected by the sensor 29a, it can be judged whether the workpiece to be processed is accurately positioned.

[0095] In this embodiment, the signal of the second positioning member 27 is detected by the sensor 29a, so that it can be accurately determined whether the workpiece to be processed is accurately positioned, which saves the process of manual judgment and is conducive to improving the processing efficiency of the processing equipment.
