Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading stations, in particular to a flexible production system loading and unloading station. Background Art

[0002] At present, in the process of production and processing of mechanical workpieces, especially when it comes to the production of some airtight parts, it is often necessary to transfer the workpiece from one production process to another during the production and processing, so that the workpiece needs to be loaded and unloaded. During the loading and unloading process, corresponding transfer loading and unloading stations are required to realize the transfer of the workpiece;

[0003] The function of the existing transfer loading and unloading station is to place the workpiece on the loading and unloading station and use the loading and unloading station to position the workpiece, so as to ensure the accurate position of the loading and unloading station and facilitate the subsequent clamping of the robot. However, the current loading and unloading station has a single function and requires workers to manually position the workpiece on the loading and unloading station, which is cumbersome to operate. In addition, a separate process for airtightness testing of the workpiece is required during the entire processing process, which delays the workpiece and affects the overall processing efficiency. Therefore, a new technical solution is needed to solve this problem. Summary of the Invention

[0020] As a preferred embodiment of the present invention, a barcode scanner is connected to the top of the console.

[0021] By adopting the above technical solution, the setting of the barcode scanner makes it possible to scan and identify the QR code representation on the surface of the workpiece, thereby facilitating the recording of whether the workpiece is qualified.

[0022] As a preferred embodiment of the present invention, a circular rotating handle is fixed to the outer peripheral wall of the turntable.

The top of the rotary joint 26 passes through the turntable 21 and the carrier block 22 through a conduit and is connected to the joint 25.

[0043] In actual use, the workpiece is first placed on the top of the carrier block 22. The four positioning blocks 23 on the top of the carrier block 22 can be accurately positioned with the positioning grooves at the bottom of the workpiece, so that the workpiece can be quickly positioned on the top of the carrier block 22, and the joint 25 on the top of the carrier block 22 can be inserted into the airtight detection hole at the bottom of the workpiece, and the turntable 21 together with the carrier block 22 can rotate, so that the staff can rotate the turntable 21 to make the workpiece rotate accordingly, thereby facilitating the appearance inspection of the workpiece surface.
