As shown in fig. 1, the tray positioning device of the present embodiment mainly includes a base plate 1, a support plate 2, an X-direction positioning assembly 3, a Y-direction positioning assembly 4, and a driving assembly. Wherein the base plate 1 is used for connecting with external equipment (such as a workbench or a pipeline); the backup pad 2 fixed connection is on bottom plate 1, and backup pad 2 is used for supporting the tray of waiting the material loading. An accommodating space is formed between the support plate 2 and the base plate 1, and most of the X-direction positioning assembly 3 and the Y-direction positioning assembly 4 connected to the support plate 2 are located in the accommodating space. The X-direction positioning component 3 is movably connected to the supporting plate 2 and is used for positioning the tray on the supporting plate 2 along the X direction. The Y-direction positioning assembly 4 is movably connected to the support plate 2 for positioning the tray in the Y-direction. The driving assembly is used for driving the X-direction positioning assembly 3 and the Y-direction positioning assembly 4 to move.

The positioning device of this embodiment includes two oppositely disposed X-direction positioning assemblies 3 and two oppositely disposed Y-direction positioning assemblies 4.

By adopting the scheme, the tray positioning device of the embodiment drives the X-direction positioning component 3 and the Y-direction positioning component 4 to move through one driving component, so that the tray placed on the supporting plate 2 is pushed to the center of the tray by the X-direction positioning component 3 and the Y-direction positioning component 4 to be overlapped with the center of the supporting plate 2, and the X-direction positioning component 3 and the Y-direction positioning component 4 always play a clamping role on the tray in the feeding process, thereby avoiding the phenomenon of shifting the tray in the feeding process of the robot and improving the accuracy of the feeding.

Specifically, as shown in fig. 2 to 4, the driving assembly of the present embodiment mainly includes a cylinder 51, a first push rod 52, a mounting shaft 53, a first turntable 54, and a second push rod 55. Wherein, cylinder 51 is fixedly mounted on bottom plate 1, and first push rod 52 is connected to output shaft 511 of cylinder 51. The mounting shaft 53 is fixedly connected to the lower side of the support plate 2, and is used for mounting and supporting the first turntable 54. The first rotary table 54 is mounted on the mounting shaft 53 by a first bearing (not shown), and the first rotary table 54 is rotatable relative to the mounting shaft 53. One end of the second push rod 55 is fixedly connected with the first rotary disc 54, and the other end is hinged with the first push rod 52. The first turntable 54 is hinged to the X-direction positioning assembly 3 by a first link 61. By adopting the above scheme, when the output shaft 511 of the air cylinder 51 stretches and contracts, the first push rod 52 can be driven to move, so that the first rotating disc 54 is driven to rotate, and then the first connecting rod 61 drives the X-direction positioning assembly 3 to move, so that the two X-direction positioning assemblies 3 move in opposite directions or move in opposite directions, and the positioning, clamping and releasing of the tray are realized. The two X-direction positioning assemblies 3 are symmetrically distributed on two sides of the first turntable 54.

As shown in fig. 6, the second turntable 56 of the present embodiment may be provided with a first step 561 and a second step 562 on an end thereof facing the first turntable 54. Wherein the first step 561 may be provided with a relief hole 563, and the relief hole 563 may avoid the hinge member where the first rotation disc 54 and the first link 61 are hinged; the second step 562 may be used to mount the second link 62, or the second link 62 may be coupled to the second step 562 of the second turntable 56 by a hinge. Further, the side of the bottom plate 1 facing the supporting plate 2 may also be provided with a relief groove 11, and likewise, the relief groove 11 may be used to relieve some fasteners or hinges. By adopting the scheme, the distance between the first rotary disc 54, the second rotary disc 56 and the bottom plate 1 can be reduced as far as possible on the premise of no interference among the components, which is beneficial to reducing the volume of the device and miniaturizing the positioning device.

In summary, the working process of the tray positioning device of the embodiment is as follows: placing the tray to be fed on the supporting plate 2, wherein the output shaft 511 of the air cylinder 51 drives the first push rod 52 to move, the second push rod 55 moves along with the first push rod and drives the first rotating disc 54 to rotate, the first rotating disc 54 drives the second rotating disc 56 to rotate through the tension spring 57, and in the process of rotating the first rotating disc 54 and the second rotating disc 56, the first push rod 52 and the second push rod 55 respectively drive the X-direction positioning assembly 3 and the Y-direction positioning assembly 4 to move, so that the stop block 34 and the roller 44 respectively prop against the edge of the tray and push the tray to the center of the tray to be substantially coincident with the center of the supporting plate 2; after the loading is finished, the output shaft 511 of the air cylinder 51 moves reversely, so that the main components in the driving assembly are driven to move reversely, and the stop block 34 and the roller 44 are separated from the tray and are released.
