Referring to fig. 1, a positioning device 100 is provided in an embodiment of the present application. The positioning device 100 is capable of simultaneously positioning a plurality of workpieces and can be used to position workpieces of different sizes. In the present embodiment, the positioning device 100 is applied to an anode process, but the present utility model is not limited to this field, and the positioning device 100 can also be applied to other processing processes, such as welding.

Referring to fig. 1 and 2, the positioning device 100 includes a conveying mechanism 10, two guiding mechanisms 20, n lifting mechanisms 30, n positioning mechanisms 40, n-1 adjusting mechanisms 50, and a bracket 60. The conveying mechanism 10, the two guiding mechanisms 20, the n lifting mechanisms 30, the n positioning mechanisms 40 and the n-1 adjusting mechanisms 50 are all arranged on the bracket 60. Wherein n is a natural number of 2 or more.

The conveyor 10 may be a conveyor, the conveyor 10 being configured to convey workpieces. In this embodiment, the conveying mechanism 10 has two parallel conveying belts, and the two conveying belts are arranged at intervals, and in the process of conveying the workpiece, two sides of the workpiece are respectively placed on the two conveying belts.

The two guide mechanisms 20 are provided on both sides of the conveying mechanism 10, and the two guide mechanisms 20 are provided to extend in the conveying direction of the conveying mechanism 10, and when the conveying mechanism 10 conveys the workpiece, the two guide mechanisms 20 guide the workpiece. The two guide mechanisms 20 can be moved in directions away from each other or toward each other, thereby changing the distance between the two guide mechanisms 20, and when the distance between the two guide mechanisms 20 is changed, the conveying mechanism 10 can convey workpieces of different sizes.

In the present embodiment, the number of the lifting mechanisms 30 is three, three lifting mechanisms 30 are disposed between two guiding mechanisms 20 and between two conveying belts of the conveying mechanism 10, and three lifting mechanisms 30 are disposed at a side facing away from the conveying mechanism 10 for conveying workpieces and are disposed at intervals along the conveying direction of the conveying mechanism 10. In other embodiments the lifting mechanism 30 may be 2, 4 or more.

The number of the positioning mechanisms 40 is three, the three positioning mechanisms 40 are respectively in one-to-one correspondence with and connected to the three lifting mechanisms 30, and the positioning mechanisms 40 are positioned at one side, which is away from the conveying mechanism 10 and is used for conveying workpieces. The positioning mechanism 40 is used to position the workpiece on the conveyor 10. Each positioning mechanism 40 is a level for placing a workpiece, and for ease of distinction, three positioning mechanisms 40 represent a first level 41, a second level 42, and a third level 43, respectively.

The number of the adjusting mechanisms 50 is two, and in this embodiment, the two adjusting mechanisms 50 are respectively connected to the first material level 41 and the third material level 43, and the two adjusting mechanisms 50 can simultaneously adjust the first material level 41 and the third material level 43 to move away from the second material level 42, or simultaneously adjust the first material level 41 and the third material level 43 to move towards the second material level 42. In other embodiments, two adjusting mechanisms 50 may be connected to the second level 42 and the third level 43, respectively.

When the conveying mechanism 10 conveys the three workpieces to the positions corresponding to the three positioning mechanisms 40, the positioning mechanisms 40 are required to position the workpieces, the lifting mechanism 30 drives the corresponding positioning mechanisms 40 to lift the workpieces away from the conveying mechanism 10, and meanwhile, the positioning mechanisms 40 position the workpieces, so that the positioned workpieces can be waited to be taken away by an external manipulator. When the positioned workpiece is taken away, the lifting mechanism 30 drives the positioning mechanism 40 to descend to the original position, on one hand, the reset positioning mechanism 40 can avoid the interference of the conveying mechanism 10 to convey the workpiece, and on the other hand, the reset positioning mechanism 40 can continuously position the next workpiece.

When the positioning device 100 needs to position a workpiece of another size, the two guide mechanisms 20 move in directions away from each other, and the two adjustment mechanisms 50 adjust the respective first and third levels 41, 43 to move in directions away from the second level 42. At this time, the positioning device 100 can position the workpiece of another size. Since the positioning device 100 can adjust the distance between the two guiding mechanisms 20 and the distance between the three positioning mechanisms 40, the positioning device 100 can be suitable for positioning workpieces with different sizes, and the universality of the positioning device 100 is further enhanced. In addition, since the types of the processing apparatuses are different, the positioning pitch requirements of each processing apparatus on the workpieces are different, the positioning pitch between the workpieces can be changed by adjusting the distances between the three positioning mechanisms 40, so that the positioning device 100 can be applied to different types, and the universality of the positioning device 100 is enhanced.

The guide section 2112 is connected to one end of the guide plate 2115 in the guide section 2111, and the distance between the guide section 2112 and the conveying mechanism 10 becomes gradually larger from the end near the conveying mechanism 10 to the end far from the conveying mechanism 10. In the present embodiment, the guide section 2112 is an arc-shaped plate, and by providing the guide section 2112 in such a manner, the work can be guided so that the work can be more easily conveyed onto the conveying mechanism 10 between the two guide sections 2111.

When the lifting driving member 32 drives the carrying seat 44 to lift and separate the workpiece from the conveying mechanism 10, the first pushing driving member 465 drives the first positioning member 462 to push the workpiece onto the first reference member 461, and at this time, the workpiece is positioned in the conveying direction along the vertical conveying mechanism 10. Since the first positioning member 462 elastically abuts against the workpiece under the action of the elastic member 467, the first positioning member 462 and the first reference member 461 do not cause pinching of the workpiece.

In this embodiment, the positioning mechanism 40 further includes a sensor 49, where the sensor 49 is mounted on the supporting seat 31 and is disposed adjacent to the stop driving member 47, and when the sensor 49 senses the workpiece, the sensor 49 sends a signal to an external controller, so that the controller controls the lifting driving member 32 to start to enable the lifting driving member 32 to drive the carrying seat 44 to lift the workpiece off the conveying mechanism 10.

Referring to fig. 1 and 2, the adjusting mechanism 50 includes an adjusting driving member 51 and two adjusting members 52.

When the adjusting driving member 51 drives the supporting seat 31 to move, the supporting seat 31 can be respectively abutted against the two adjusting members 52, and when the supporting seat 31 is abutted against the adjusting members 52, the supporting seat 31 stops moving, and the two adjusting members 52 are used for limiting the limiting position of the supporting seat 31. When the positioning device 100 needs to position a workpiece with a larger size, the two adjusting driving members 51 drive the corresponding supporting seats 31 to slide so as to increase the spacing between the three positioning mechanisms 40, namely, the positioning mechanism 40 of the first material level 41 and the positioning mechanism 40 of the third material level 43 move towards the positioning mechanism 40 far away from the second material level 42. By enabling the positioning device 100 to position workpieces of different sizes under the influence of the adjustment mechanism 50, versatility of the positioning device 100 is enhanced.

The working process of the positioning device 100 provided in the embodiment of the present application is approximately:

before the conveying mechanism 10 conveys the workpiece, the stop driving piece 47 of the third material level 43 drives the stop piece 48 to ascend for stopping the workpiece, and the stop pieces 48 of the first material level 41 and the second material level 42 are in a descending state, at this time, the conveying mechanism 10 moves with the workpiece, the workpiece moves to the third material level 43 under the guiding action of the guide pieces 21 in the two guiding mechanisms 20 and abuts against the stop pieces 48, and the workpiece stops moving under the action of the stop pieces 48; the lifting driving member 32 drives the carrying seat 44 to lift and lift the workpiece off the conveying mechanism 10, when the carrying seat 44 stops lifting, the first pushing driving member 465 drives the first positioning member 462 to push the workpiece to the first reference member 461, the second pushing driving member 466 drives the second positioning member 464 to push the workpiece to the second reference member 463, and the workpiece is positioned at this time. Then, the stop driving member 47 of the second stock level 42 drives the stop member 48 to rise, and the conveying mechanism 10 conveys the second workpiece to the second stock level 42, and after the workpiece is stopped by the stop member 48 of the second stock level 42, the second stock level 42 repeats the same operation as the third stock level 43 to position the second workpiece. By repeating the above operation, the first level 41 can complete the positioning of the third workpiece. Finally, the external robot may simultaneously remove the workpieces from the three positioning mechanisms 40. When the robot removes the workpieces from the positioning mechanisms 40, the first positioning members 462 and the second positioning members 464 of the three positioning mechanisms 40 are spaced apart from the workpieces to facilitate the workpieces being removed.

When the workpiece to be positioned is replaced, the displacement driver 22 can drive the base plate 2113 to slide, thereby increasing or decreasing the distance between the two guides 21.
