Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following embodiments, features of the embodiments may be combined with each other without conflict.

Referring to fig. 1, an embodiment of the present application provides a turnover positioning device 100 for turning over and positioning a workpiece 200. The turn-over positioning device 100 comprises a workbench 10, a turn-over mechanism 20, a positioning mechanism 30 and a feeding mechanism 40. The feeding mechanism 40 is arranged above the workbench 10, and the feeding mechanism 40 is used for conveying the workpiece 200 to the turnover mechanism 20. The feeding mechanism 40 may include, but is not limited to, a suction cup or the like. The workpiece 200 includes oppositely disposed upper and

lower surfaces

201, 202 and a side 203 connecting the upper and

lower surfaces

201, 202. The workpiece 200 may be in the form of a sheet, a plate, or the like, and the present application is not limited thereto.

Referring to fig. 2, the turnover mechanism 20 is disposed on the worktable 10. The turnover mechanism 20 comprises a first driving component 21, a first pushing component 22 fixedly connected with the first driving component 21, two inclined blocks 23 arranged on two opposite sides of the first pushing component 22, and a workpiece bearing table 24 arranged on one side of the inclined blocks 23 far away from the first driving component 21. In this embodiment, two sets of the turning-over mechanism 20 are provided, and the two sets of the turning-over mechanism 20 have the same structure and function. Two sets of turnover mechanisms 20 are oppositely arranged along the driving direction of the first driving assembly 21 so as to simultaneously turn over two workpieces. In other embodiments, the turnover mechanism 20 can be a set for turning over a workpiece.

As shown in fig. 2, the swash block 23 may include a horizontal surface 231, an arc surface 232, an inclined surface 233, and a vertical surface 234, which are sequentially connected, and the vertical surface 234 is connected to the table 10. The horizontal plane 231 is substantially parallel to the surface of the table 10 for placing the workpiece. The width of the horizontal plane 231 is smaller than that of the workpiece, so that the workpiece slides downwards along the arc surface 232 under the action of gravity. The cambered surface 232 protrudes towards the direction close to the workpiece bearing table 24, and the arrangement of the cambered surface 232 can reduce the scratch of the workpiece in the process of sliding the workpiece downwards. The inclined surface 233 is inclined downward toward the workpiece carrier 24, and the inclined surface 233 forms an included angle (acute angle, preferably 10 ° to 30 °) with the vertical direction, which is beneficial to the continuous downward sliding of the workpiece. The vertical surface 234 extends in the vertical direction to the work table 10, and the vertical surface 234 facilitates sliding the workpiece 200 (see fig. 1) down to the workpiece support 24, when the workpiece 200 is turned by 90 ° compared to the initial state of being placed on the horizontal plane 231, and the side surface 203 (see fig. 1) thereof is in contact with the workpiece support 24.

Referring to fig. 2, the workpiece supporting stage 24 may include a bottom plate 241, a supporting plate 242, and a supporting plate 243 connecting the bottom plate 241 and the supporting plate 242. The side of the bottom plate 241 is provided with two notches 2411. The gap 2411 penetrates through the bottom plate 241 along the thickness direction of the bottom plate 241, each gap 2411 contains one inclined block 23, and the vertical surface 234 of each inclined block 23 can be abutted against the inner wall of the gap 2411. In other embodiments, the number of the gaps 2411 may be one, and two inclined blocks 23 are accommodated in the gaps 2411. The two inclined blocks 23 are arranged at intervals, and the distance between the two inclined blocks 23 is required to be set to enable the first material pushing assembly 22 to pass through. The supporting plate 243 is obliquely arranged relative to the bottom plate 241 and the bearing plate 242, and the supporting plate 243 has a certain included angle (acute angle, preferably 30-60 °) with the vertical direction, so that the supporting plate can support the upper surface 201 (see fig. 1) of the workpiece 200 (see fig. 1), and is beneficial to the subsequent continuous overturning of the workpiece 200 (see fig. 1).

As shown in fig. 2, the positioning mechanism 30 is disposed on the working platform 10, the positioning mechanism 30 includes a second driving assembly 31, a second pushing assembly 32 fixedly connected to the second driving assembly 31, a first positioning block 33 and a second positioning block 34 disposed on the bearing plate 242, and the second positioning block 34 is disposed on a side of the workpiece carrying platform 24 away from the second driving assembly 31. In this embodiment, the second pushing assembly 32 is substantially rectangular. In this embodiment, the number of the first positioning blocks 33 is two, and the two first positioning blocks 33 are disposed along the length direction of the supporting plate 242. It can be understood that the length direction of the carrier plate 242 coincides with the length direction of the workpiece 200 (see fig. 1). In other embodiments, the number of the first positioning blocks 33 may be one or more. When there is only one first positioning block 33, the first positioning block 33 is preferably disposed at a middle position of the loading plate 242 in the length direction so as to correspond to a middle position of a long side of the workpiece 200 (see fig. 1). The first positioning block 33 and the second positioning block 34 are substantially square blocks. The first positioning block 33 is used for abutting against a long side of the workpiece 200 (see fig. 1), and the second positioning block 34 is used for abutting against a short side of the workpiece 200 (see fig. 1). The workpiece 200 is positioned by adjusting the long side of the workpiece 200 to abut against the first positioning block 33 and adjusting the short side to abut against the second positioning block 34.

Further, the bottom plate 241 includes a first surface 2412 facing away from the working platform 10, the bearing plate 242 includes a second surface 2421 facing away from the working platform 10, and the abutting plate 243 connects the first surface 2412 and the second surface 2421. The second surface 2421 is higher than the first surface 2412 in a height direction of the table 10 (i.e., a thickness direction of the base plate 241, a vertical direction). The bottom plate 241, the abutting plate 243 and the bearing plate 242 form a step surface together.

In some embodiments, the top surface of the second positioning block 34 is higher than the second surface 2421 along the height direction of the worktable 10. Thus, the second positioning block 34 can support the short edge of the workpiece 200, thereby achieving the purpose of positioning.

In some embodiments, the second surface 2421 of the carrier plate 242 is recessed to form a groove 2422, and the first positioning block 33 is disposed in the groove 2422. In this embodiment, the number of the grooves 2422 is two, and each groove 2422 accommodates a first positioning block 33. In other embodiments, the number of the grooves 2422 may also be one or more than two to accommodate one, two or more than two first positioning blocks 33, and the application is not limited to the number of the grooves 2422 and the number of the first positioning blocks 33. The top surface of the first positioning block 33 is higher than the second surface 2421 in the height direction of the table 10. Thus, the first positioning block 33 can hold the long side of the workpiece 200, thereby achieving the purpose of positioning.

In some embodiments, the driving direction of the first driving assembly 21 is substantially perpendicular to the driving direction of the second driving assembly 31. In this embodiment, the driving direction of the first driving unit 21 corresponds to the short side direction of the workpiece 200, so that the workpiece 200 moves in the short side direction thereof; the driving direction of the second driving unit 31 corresponds to the longitudinal direction of the workpiece 200 to move the workpiece 200 along the longitudinal direction thereof. The first drive assembly 21 and the second drive assembly 31 may be, but are not limited to, a pneumatic cylinder or the like, the pneumatic cylinder including a piston rod 211 (see fig. 5).

In some embodiments, referring to fig. 5, the first pushing assembly 22 includes a main body 221 connected to the first driving assembly 21, and an extending portion 222 protruding from a portion of the main body 221 toward the workpiece carrier 24. In this embodiment, the extension portions 222 are substantially long and two, and the two extension portions 222 are substantially symmetrically disposed. The extension 222 is used to flip the workpiece 200.

In some embodiments, the turn-over positioning device further comprises a driving mechanism (not shown) connected to the feeding mechanism 40 and configured to drive the feeding mechanism 40 to move. The driving mechanism may be, but is not limited to, a pneumatic cylinder or the like.

The following describes a procedure of turning and positioning the workpiece 200 by the turn-over positioning device 100.

Referring to fig. 1 and 3, the feeding mechanism 40 sucks the upper surface 201 of the workpiece 200 and conveys the workpiece 200 to the sloping block 23 of the turnover mechanism 20. At this time, the lower surface 202 of the workpiece 200 is in contact with the horizontal surface 231 (see fig. 2) of the swash block 23.

Then, referring to fig. 4, the workpiece 200 slides down to the workpiece supporting table 24 under the action of gravity and the arc surface 232 (see fig. 2) and the inclined surface 233 (see fig. 2) of the inclined block 23. At this time, the workpiece 200 is turned substantially 90 °, the side surface 203 contacts the bottom plate 241 of the workpiece support 24, and the upper surface 201 abuts against the abutting plate 243 (see fig. 2).

Referring to fig. 5, when the first driving assembly 21 (cylinder) is activated, the piston rod 211 extends to drive the first pushing assembly 22 to move toward the workpiece 200 until the extension portion 222 contacts with the workpiece 200, and the extension portion 222 of the first pushing assembly 22 continues to move to push the workpiece 200 to turn over until the upper surface 201 of the workpiece 200 completely contacts with the supporting plate 242 and the lower surface 202 is exposed. The piston rod 211 continues to move, and the main body 221 of the first pushing assembly continues to move against the workpiece 200 until the long edge of the workpiece 200 contacts the first positioning block 33, and the driving is stopped. At this time, the positioning of the turn-over and the long side of the workpiece 200 is completed.

Referring to fig. 6, when the second driving assembly 31 (cylinder) is activated, the piston rod 211 of the second driving assembly extends to drive the second pushing assembly 32 to move toward the workpiece 200, and the second pushing assembly 32 contacts with the short side of the workpiece 200 to drive the workpiece 200 to move toward the second positioning block 34 until the other short side of the workpiece 200 abuts against the second positioning block 34, and the driving is stopped. At this time, the positioning of the short side of the workpiece 200, that is, the turning-over and positioning of the workpiece 200 are completed.

The turnover positioning device 100 provided by the application can automatically turn over the workpiece 200 through the turnover mechanism 20, and can adjust the positions of the long edge and the short edge of the workpiece 200 through the positioning mechanism 30 to position the workpiece 200, so that the operation is simple, the efficiency is high, the positioning is accurate, and the workpiece damage is small.

The above description is a few specific embodiments of the present application, but in practical applications, the present application is not limited to these embodiments. Other modifications and variations to the technical concept of the present application should fall within the scope of the present application for those skilled in the art.
