Description

Technical Field

[0001] This utility model relates to the field of workpiece transfer technology, specifically to a workpiece transfer device. Background Technology

[0002] Existing workpiece transfer devices utilize lifting mechanisms and moving platforms to transfer workpieces from one platform to another. However, during the transfer process, the workpiece's stopping position on the moving platform is sometimes inaccurate, and it may even exceed the designated stopping position, thus affecting the normal operation of the workpiece transfer device and exhibiting a lack of operational stability. Utility Model Content

[0003] The purpose of this utility model is to provide a workpiece transfer device with a blocking mechanism. This transfer device can effectively prevent the workpiece from exceeding the stopping position by blocking the workpiece, thereby ensuring the normal operation of the workpiece transfer device and improving the stability of the transfer work.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A workpiece transfer device with a blocking mechanism includes a workpiece transfer lifting frame and a workpiece conveying frame, and also includes a blocking mechanism. The blocking mechanism includes a fixed crossbeam, a workpiece blocking plate, and a top pressure beam. The eccentric part of the workpiece blocking plate is hinged to the fixed crossbeam via a hinge shaft. The fixed crossbeam is installed at the end of the workpiece conveying frame, and the top pressure beam is installed at the end of the workpiece transfer lifting frame. The upper surface of the top pressure beam is provided with a top pressure slope. The workpiece blocking plate remains upright under its own weight. The upper end of the workpiece blocking plate is above the workpiece conveying frame to block the workpieces on the conveyor belt of the workpiece conveying frame. During the upward movement of the workpiece transfer lifting frame, the lower end of the workpiece blocking plate moves along the top pressure slope and rotates. When the workpiece transfer lifting frame is flush with the workpiece conveying frame, the upper end of the workpiece blocking plate rotates to a position below the workpiece to release the obstruction.

[0006] Furthermore, a wear-resistant plate is laid on the top pressure slope to protect it and prevent wear.

[0007] Furthermore, a bearing shaft perpendicular to the plate surface is installed at the lower end of the workpiece blocking plate, and a roller is installed on the bearing shaft for contacting the top pressing inclined surface.

[0008] Furthermore, a conveyor belt is installed on the workpiece transfer lifting frame.

[0009] Furthermore, the workpiece transfer lifting frame is mounted on a slider, the slider is located on a vertical slide rail, the vertical slide rail is mounted on a transfer frame, and the motor drives the workpiece transfer lifting frame to move up and down along the vertical slide rail through a transmission mechanism.

[0010] The beneficial effects of this utility model are as follows: The transfer device of this application can effectively prevent the workpiece from exceeding the stopping position by using a blocking mechanism, thereby ensuring the normal operation of the workpiece transfer device and improving the stability of the transfer work; In particular, the blocking mechanism is cleverly designed so that when the transfer device leaves, the blocking mechanism can block the path of the workpiece under its own weight. When the workpiece transfer lifting frame and the workpiece conveying frame of the transfer device are aligned and the workpiece needs to be transferred, the blocking mechanism can automatically release the obstruction under the pressure of the workpiece transfer lifting frame.
