Referring to fig. 1 and 2, fig. 1 is a schematic structural view illustrating an automatic positioning mechanism 100 in an initial state according to an embodiment of the present disclosure; fig. 2 is a schematic structural view showing the tray 200 after positioning. Wherein the automatic positioning mechanism 100 includes: the positioning device comprises a first positioning assembly 10, a second positioning assembly 20, a power assembly 30, a first motion assembly 40, a transmission assembly 50 and a second motion assembly 60.

The first positioning component 10 is provided with a first positioning datum plane 11; the second positioning assembly 20 is disposed at one side of the first positioning assembly 10, and a second positioning datum plane 21 is formed on the second positioning assembly 20; the first actuating assembly 40 is in driving connection with the power assembly 30, and the first actuating assembly 40 is used for driving the tray 200 to abut against the first positioning reference surface 11; the transmission assembly 50 is in transmission connection with the first motion assembly 40; the second actuating assembly 60 is in transmission connection with the transmission assembly 50, and the second actuating assembly 60 is used for driving the tray 200 to abut against the second positioning reference surface 21.

In summary, the technical solution of the present embodiment has the following advantages: the automatic positioning mechanism 100 of the above scheme is applied to a chip production device to realize automatic positioning of the tray 200. After the tray 200 is released into the positioning cavity by the mechanical arm, the power assembly 30 starts and outputs a driving force, the driving force is directly transmitted to the first actuating assembly 40, so that the first actuating assembly 40 pushes one side of the tray 200 and the tray 200 is in abutting contact with the first positioning reference surface 11, and the driving force is also transmitted to the second actuating assembly 60 through the transmission assembly 50, so that the second actuating assembly 60 pushes the other side of the tray 200 and the tray 200 is in abutting contact with the second positioning reference surface 21, thereby completing the automatic positioning operation of the tray 200. Compared with the prior art, the automatic positioning mechanism 100 of the present embodiment can complete the positioning operation of the tray 200 toward the first positioning reference surface 11 and the second positioning reference surface 21 by using one power assembly 30, and not only has simple structural composition and control logic, low manufacturing and using cost, but also has high positioning accuracy.

It is understood that the tray 200 in this embodiment is rectangular, but may be circular, triangular, etc. in other embodiments. Accordingly, the first positioning member 10 is disposed on one of the long sides of the rectangular tray 200, the second positioning member 20 is disposed on one of the wide sides of the rectangular tray 200, and the first positioning reference plane 11 and the second positioning reference plane 21 are perpendicular to each other. Thus, when the tray 200 is pushed by the first actuating assembly 40 and the second actuating assembly 60, the adjacent one of the long sides and one of the wide sides can be in abutting contact with the first positioning reference surface 11 and the second positioning reference surface 21, respectively, thereby achieving positioning and position correction of the tray 200. The working principle and the implementation structure are simple, and the reliability is high.

The power assembly 30 in this embodiment includes a cylinder and a cylinder shoe. The cylinder is mounted on a cylinder shoe so as to be adaptable to the rotational action of the drive assembly 50 or the like.

With continued reference to fig. 1 and 2, in some embodiments, the first positioning component 10 includes at least two first positioning bodies 12, and at least two first positioning bodies 12 are disposed coplanar to form the first positioning reference plane 11; the second positioning assembly 20 includes at least two second positioning bodies 22, and at least two second positioning bodies 22 are disposed in a coplanar manner to form the second positioning reference plane 21. Therefore, the first positioning reference surface 11 and the second positioning precise surface are formed in a simple manner and have high feasibility of implementation. And adopt two at least first locating bodies 12 and two at least second locating bodies 22 butt the long limit and the broadside of tray 200 respectively, can make the atress more even, better to the support location effect of tray 200.

For example, in some embodiments the first actuating assembly 40 is provided as a rigid pusher set and the second actuating assembly 60 is provided as an elastic pusher set that contacts the tray 200 against prior to the rigid pusher set during clamping positioning of the tray 200. The elastic push rod group has certain avoiding capacity, so that when the elastic push rod group contacts and clamps the tray 200 firstly, the rigid push rod group can also easily push the tray 200, the elastic push rod group cannot cause interference, and meanwhile, the tray 200 is prevented from being scratched due to overlarge friction resistance.

During the process of releasing the tray 200, the rigid push rod set is released from the tray 200 before the elastic push rod set. The rigid push rod group and the elastic push rod group are sequentially separated from the contact tray 200, the action logic is simple and clear, the elastic push rod group is in contact with the tray 200 for a long time, the positioning is more stable, and the chip falling caused by instant elastic rebound of the tray 200 is avoided.

With reference to fig. 1, in addition, on the basis of any of the above embodiments, the first actuating assembly 40 includes a first actuating hinge 41, a first actuating hinge seat 42 and a rigid push rod 43, a middle portion of the first actuating hinge 41 is hinged to the power assembly 30, one end of the first actuating hinge 41 is hinged to the transmission assembly 50, the other end of the first actuating hinge 41 is hinged to the first actuating hinge seat 42, and the rigid push rod 43 is fixedly connected to the first actuating hinge 41. The driving force output by the power assembly 30 can be transmitted to the rigid push rod 43 and the transmission assembly 50 via the first actuating hinge 41, respectively, so that the rigid push rod 43 can rotate to complete the positioning of abutting against and pushing the tray 200, and the second actuating assembly 60 can be driven to rotate to abut against and push the tray 200. The force transmission path is short, and the rotation response speed of the rigid push rod 43 is high.

Preferably, the first actuation hinge 41 comprises a first section and a second section, the first section being angularly connected to the second section. This ensures that the resilient pusher set contacts the tray 200 prior to the rigid pusher set abutting during the clamping positioning of the tray 200. During the process of releasing the tray 200, the elastic push rod set is released to be separated from the tray 200 before the rigid push rod set. That is, the first and

second actuating assemblies

40 and 60 are sequentially actuated step by step, and the positioning reliability of the tray 200 is higher. For example, the first section is connected to the second section at a right angle of 90 ° in this embodiment, which is more advantageous for driving the rigid push rod 43 to move with higher response speed and shorter rotation path.

With continued reference to fig. 1, in some embodiments, the transmission assembly 50 includes a first transmission hinge 51, a second transmission hinge 52, a third transmission hinge 53 and a transmission hinge seat 54, one end of the first transmission hinge 51 is hinged to the first actuation hinge 41, the other end is hinged to one end of the second transmission hinge 52 and one end of the third transmission hinge 53, the other end of the third transmission hinge 53 is hinged to the transmission hinge seat 54, and the other end of the second transmission hinge 52 is hinged to the second actuation assembly 60. Therefore, the driving force output by the power assembly 30 is more stably and accurately transmitted to the second moving assembly 60, so as to drive the second moving assembly 60 to complete the positioning operation of the tray 200 to the second positioning reference surface 21.

For example, in some embodiments, the second actuating assembly 60 includes a second actuating hinge 61, a second actuating hinge seat 62, and an elastic push rod 63, wherein one end of the second actuating hinge 61 is hinged to the second transmission hinge 52, the other end is hinged to the second actuating hinge seat 62, and the elastic push rod 63 is fixedly connected to the second actuating hinge 61. The second actuating hinge base 62 plays a role of fixing the second actuating hinge 61 and the elastic push rod 63 and providing a pivot point, so that when the second actuating hinge 61 is pushed and pulled by the second transmission hinge 52, the elastic push rod 63 can be synchronously driven to rotate to realize clamping positioning or releasing of the tray 200.

In order to avoid influencing the smoothness of the movement of the tray 200 pushed by the first actuating assembly 40 and ensure that the tray 200 is not scratched, the elastic push rod 63 should have a certain deformation avoiding capability. For example, in some embodiments, the elastic push rod 63 includes a spring 631 and a push rod body 632, one end of the spring 631 is connected to the second actuating hinge 61, and the push rod body 632 is connected to the other end of the spring 631. The spring 631 provides a certain elastic pressure to the push rod body 632, so that the push rod can better press against the tray 200, and ensure that the tray 200 is tightly contacted against the second positioning reference surface 21. In addition, the spring 631 provides a certain retraction and escape stroke of the pusher body 632 to reduce frictional resistance and wear with the tray 200 as the tray 200 is pushed by the first actuating assembly 40.

On the basis of any of the above embodiments, the rigid push rod 43 and the elastic push rod 63 are provided with rollers at one end for contacting the tray 200. The rollers are matched with the side surfaces of the tray 200 in a rolling manner, so that the rolling friction resistance is smaller, the abrasion is reduced while the tray 200 is ensured to move smoothly, and the service lives of the tray 200, the rigid push rods 43 and the elastic push rods 63 are prolonged.

In addition, the present application also provides a chip manufacturing apparatus, which includes the automatic positioning mechanism 100 according to any of the above embodiments.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
