Description

Technical Field

[0001] The utility model relates to a side shaft threading and visual detection system for complex assembly parts. Background Art

[0002] During the production process of assemblies, traditional side-through shaft and visual inspection systems usually rely on manual operation or semi-automated equipment to complete the process. For example, a mounting shaft is manually placed, and then the machine is started to hit the mounting shaft and install the mounting shaft on the assembly. The poor positioning accuracy can easily lead to assembly errors. This method is neither safe nor efficient. In addition, the monitoring system of existing technology is not comprehensive, and missed inspections may occur, resulting in unstable assembly quality. This problem is particularly significant during the production process of complex assemblies.

[0003] Therefore, a side-through shaft and visual inspection system for complex assemblies is needed to provide a more efficient and accurate solution for the production of complex assemblies. Utility Model Content

The system adopts an automated multi-positioning device and a through-the-axis module, which is more efficient. The visual inspection module provides detection without blind spots and improves detection accuracy. The following is a specific solution:

[0005] A side-threading and visual inspection system for complex assemblies, comprising a workbench and an assembly, a notch is provided at the central position of the upper side of the workbench, at least one positioning device is provided at the edge of the notch, at least one threading module is provided on each side of the notch, the threading module comprises a shell and a wheel disc, an inclined placement bin is provided inside the shell, an installation bin is provided inside the placement bin, the outlet of the placement bin corresponds to the notch on the wheel disc, a falling channel is provided on the lower side of the wheel disc, a guide rail is provided on the lower side of the shell, the guide rail is provided on the workbench, a slider, a connecting rod and a top block are provided on the guide rail, a guide member is fixedly provided on one side of the top block, a bracket is further provided on the workbench, at least one visual inspection module is provided on the bracket, at least one visual inspection module is provided on the threading module, and at least one visual inspection module is provided on the lower side of the notch.

A second visual inspection module is provided on one of the through-axis modules, and the extension line of the lens of the second visual inspection module is aligned with another guide. A third visual inspection module is provided on the lower side of the notch through the bracket, and the extension line of the lens of the third visual inspection module is aligned with the bottom surface of the assembly.

[0007] For more accurate detection, the detection range of the first visual inspection module includes the top block, the detection range of the second visual inspection module includes another top block, and the detection range of the first visual inspection module includes the positioning device and the assembly part.

[0008] In order to better match the detection range of the lens of the detection module, the shape of the notch is a rectangle, and the notch has a long side and a wide side.

[0009] In order to better position the assembly, the positioning device is arranged on the long side of the notch. There are two positioning devices, and the positioning device includes a positioning cylinder, a positioning block and a protrusion. The protrusion is arranged on the upper side of the positioning block. The positioning cylinder is used to move the positioning block vertically upward, and the protrusion can cooperate with the assembly.

[0010] In order to better thread the shaft, two shaft threading modules are provided, and the shaft threading modules are respectively arranged on one side of the two wide sides.

The wheel disc is provided with at least 8 notches, and the diameter of the notches is larger than the diameter of the installation shaft. A vertically arranged falling channel is provided directly below the wheel disc, and the width of the falling channel is larger than the diameter of the installation shaft. One side of the falling channel has an opening, and the opening is used to cooperate with the movement of the top block, and the top block is used to hit the installation shaft in the falling channel; through the setting of the automated double-sided axis threading module, the automation of the axis threading module speeds up the axis threading efficiency.

[0013] In order to better provide power to the wheel disc, the shaft-through module is driven by a motor installed in the housing, and the motor is connected to the wheel disc through a belt.

[0014] Beneficial effects: By setting up an automated shaft threading module, the operator only needs to place the installation shaft in the placement bin once, and the installation column can be automatically set through the movement of the guide rail, optimizing the production process. While installing the rotating shaft on the side, the overall part status can be inspected through mechanical vision to see if there is any missing or insufficient installation. Overall, this device speeds up production efficiency and improves assembly accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
