Description

An automatic turning mechanism for sheet workpieces

technical field

The utility model relates to an overturning mechanism, in particular to a mechanism for overturning sheet workpieces (such as zipper pulls).

Background technique

In many industries, such as the production process of the zipper, it is necessary to involve the zipper slider, a piece of workpiece, to transport the zipper slider to the corresponding station. Since the zipper slider has a front and a reverse side, in the production process, it is necessary to For a specific front or reverse side, when the zipper puller is on the reverse side, and the front state is required at this time, it needs to be turned over manually by manual operation, so as to prepare for the next process. For other sheet-shaped workpieces of the same type, some of them also need to distinguish the front and back sides. The current practice is often to manually turn them over according to the requirements to ensure that they are in the front state or the reverse state, and do it for the next process. get ready. Because it is operated by workers, as the working hours increase, the fatigue of the workers will gradually increase, resulting in a decrease in operating efficiency, and it is prone to mistakes, which is not conducive to batch processing.

detailed description

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in the accompanying drawing 1, the utility model discloses a sheet-shaped workpiece automatic turning mechanism, including a base 7 and a work table 11, the upper end of the base 7 is provided with a driving device, and the work table 11 is provided with a push block 1 and The guide block 4, the push block 1 and the guide block 4 are arranged oppositely at intervals, the driving device is connected with the drive block to drive the push block to move back and forth along the direction of the guide block, and the side wall of the base 7 is provided with a turning piece 6, and the turning piece 6 moves through the The guide block 4 is used to place the sheet workpiece 3 between the push block 1 and the guide block 4 . A spring 8 is arranged between the guide block 4 and the base 7 , and one end of the spring 8 is attached to the guide block 4 , and the other end is attached to the side wall of the base 7 .

The side of the guide block 4 facing the push block 1 is set as an inclined surface. The side of the pushing block 1 facing the guide block 4 is set as an inclined surface, and the bottom of the inclined surface has a horizontally extending end 2, which can be used to push the sheet workpiece.

The guide block 4 is provided with a through groove 5, and the turning piece 6 is inserted through the through groove 5, and the turning piece plays a role of turning over the sheet workpiece.

Driving device comprises cylinder 9 and linear guide rail 10, and linear guide rail 10 is connected with cylinder 9, and push block and guide block all are contained on the linear guide rail by slide block, and push block is connected with cylinder. The cylinder drives the push block to move back and forth along the linear guide rail to push the guide block.

The utility model is used in conjunction with a feeding mechanism, which sends sheet workpieces to between the push block and the guide block. When turning over is required, the cylinder drives the push block to move towards the guide block, and the push block pushes the sheet workpiece to the guide block during the movement. As the push block moves, the sheet-like workpiece moves upward from the inclined surface of the guide block. When the distance between the horizontal extension end of the bottom surface of the push block and the bottom surface of the guide block is close to the thickness of the sheet workpiece, the top surface of the push block contacts the top surface of the guide block, and the sheet workpiece just moves to the position of the through groove of the guide block. As the push block continues to move, the guide block is pushed to move by the push block, and the spring is compressed. Along with the movement of the guide block, the reversing piece passes through the through groove of the guide block and exerts a force on the sheet-shaped workpiece opposite to the moving direction of the guide block until the sheet-shaped workpiece is turned over. At this moment, the cylinder stops running, and the pushing block no longer moves. The cylinder runs again, driving the push block to move away from the guide block and return to the initial position, and the guide block is automatically returned to the initial position by the stretching force of the spring, realizing the turning of the sheet-shaped workpiece, and the cycle is repeated accordingly.

It should be noted that the above description is not a limitation to the technical solution of the utility model, and any obvious replacements are within the protection scope of the utility model without departing from the inventive concept of the utility model.
