Detailed Description

The technical solution of the present invention is further explained below with reference to the specific embodiments and the accompanying drawings.

Referring to fig. 1 to 3, the present embodiment provides a workpiece turnover device, which includes a frame 1, a worktable 2 disposed on the frame 1, a turnover part 3 suspended on the worktable 2 and having an inclined upper surface 31, and a blocking part 4 suspended on the worktable 2 and spaced from the turnover part 3 along a first direction (a direction from right to left in fig. 2), where the suspension means that the lower surface and the upper surface of the worktable 2 are spaced along a vertical direction. Referring to fig. 1, the top of the blocking member 4 is higher than the bottom of the reversing member 3, and the blocking member 4 is used for matching with the reversing member 3 to enable the reversed workpiece to fall onto the workbench 2 from the interval between the two.

In the present embodiment, a first side surface 41 of the blocking member 4 facing the reversing member 3 (a right side surface of the blocking member 4 in fig. 2) is a vertical plane for fitting the workpiece to fall vertically. Through setting up this vertical plane, the left surface that makes the work piece upset back can laminate each other with it to vertical whereabouts. In order to prevent the workpiece from being too fast and still having a tendency of rolling forward after falling, the distance between the lower surface of the blocking piece 4 and the upper surface of the workbench 2 along the vertical direction is the same as the height of the overturned workpiece, so that the workpiece falling onto the workbench 2 can be prevented from continuously rolling forward.

Referring to fig. 2, the inclined upper surface 31 of the flipper 3 is inclined downward in a direction approaching the blocker 4 (i.e., right-to-left direction), and by setting the inclination angle and the inclination length of the inclined upper surface 31, it is ensured that the workpiece can be flipped when falling freely.

The workpiece turnover device further comprises two groups of limiting assemblies 5 arranged on the workbench 2 and used for limiting two ends of the workpiece respectively, and a driving mechanism 6 arranged on the rack 1 and used for driving the workpiece to move between the two groups of limiting assemblies 5 along a first direction, wherein the two groups of limiting assemblies 5 are arranged at intervals along a vertical first direction.

In this embodiment, the two sets of limiting assemblies 5 each include a first limiting strip 51 and a second limiting strip 52 connected in sequence along a direction away from the blocking member 4, the two first limiting strips 51 are arranged relatively close to each other along the first direction, and the two second limiting strips 52 are respectively parallel to the first direction. Through the arrangement, even if the workpiece is not perpendicular to the first direction after falling, when the driving mechanism 6 drives the workpiece to move along the first direction, the direction of the workpiece can be corrected under the limit of the two end limit components 5, so that the whole workpiece is perpendicular to the first direction. Referring to fig. 3, one end of the first stopper 51 is disposed below the blocking member 4.

The limiting assembly 5 is slidably arranged relative to the workbench 2 along a first direction, the turnover device further comprises a pair of abutting assemblies 7 arranged on the workbench 2 and used for abutting against the second limiting strips 52 in a one-to-one correspondence manner, and the pair of abutting assemblies 7 are respectively arranged on two sides of each second limiting strip 52, which deviate from each other. Referring to fig. 3, a pair of abutting assemblies 7 are respectively disposed outside the two second limiting strips 52.

In the present embodiment, the abutting assembly 7 includes an abutting seat 71 disposed on the worktable 2, a sliding block 72 slidably disposed in the abutting seat 71 along a first direction, and a fixing bolt (not shown) for fixing the sliding block 72 on the abutting seat 71. The sliding blocks 72 are used for abutting against the outer sides of the corresponding second limiting strips 52, and the distance between the two sliding blocks 72 is adjusted according to the length of the workpiece, so that the distance between the two second limiting strips 52 is correspondingly adjusted.

In fact, since the distance between the two first limiting strips 51 is large, and the workpiece is located at the central position of the two first limiting strips 51, even if the workpiece is not perpendicular to the first direction, when the driving mechanism 6 drives the workpiece to move to be close to the second limiting strips 52, the workpiece will abut against the limiting assemblies 5 at the two ends. And because spacing subassembly 5 quality is great, and actuating mechanism 6's drive direction is first direction, and spacing subassembly 5 that the work piece butt both ends can not cause spacing subassembly 5 to take place the displacement, only can carry out spacingly through spacing subassembly 5 to the work piece, makes its whole perpendicular first direction to correct the deflection that the work piece took place when the whereabouts.

Referring to fig. 1, the driving mechanism 6 includes a cylinder 61 disposed on the frame 1 and below the worktable 2, a first push rod 62 movably disposed in the cylinder 61 along the longitudinal extension direction thereof, a connecting seat 63 connected to the extending end of the first push rod 62, a guide seat 64 disposed on the worktable 2, and a second push rod 65 connected to the connecting seat 63 and slidably disposed in the guide seat 64 along the longitudinal extension direction thereof. The second push rod 65 and the guide seat 64 are arranged above the workbench 2, the second push rod 65 is arranged below the turnover part 3 and the blocking part 4 and used for pushing the workpiece therein, and the first push rod 62 and the second push rod 65 are respectively parallel to the first direction. In this embodiment, there are two second push rods 65, and the two second push rods 65 are arranged at intervals along the vertical first direction. By providing two first push rods 62, the workpiece can be prevented from deflecting due to the thrust when the workpiece is driven to move in the first direction.

Referring to fig. 3, the workpiece turnover device further includes positioning members 8 disposed on the worktable 2 and spaced from the limiting members 5 along the first direction. Through setting up this setting element 8, actuating mechanism 6 drive work piece is contradicted this setting element 8 after, and the work piece stops to remove, can be convenient for the smooth clamp of manipulator get.

The following specifically explains the working process of this embodiment:

the manipulator places the workpiece on the inclined upper surface 31 of the turnover part 3, the workpiece is turned over in the free falling process, abuts against the blocking part 4 after turning is finished, and falls onto the workbench 2 through the interval between the blocking part 4 and the turnover part 3;

then the driving mechanism 6 drives the workpiece to move along the first direction, under the correction of the limiting assemblies 5 at the two ends, the workpiece is vertical to the first direction and then props against the positioning piece 8, and the manipulator takes away the workpiece after being overturned and positioned.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
