TECHNICAL FIELD

[0001] The utility model relates to the field of sealing element quality detection, in particular to annular workpiece reversing detection device. BACKGROUND

[0002] The rubber sealing ring is a flexible annular workpiece, and the material is selected according to the specific working condition. The adaptive ring structure is formed through processing technology. The sealing state is formed in the matched position of the equipment to prevent the internal material from leaking out and the external impurities from invading. The rubber sealing ring is widely used in the fields of semiconductor manufacturing equipment, electronic equipment protection, precision electronic component protection, and new energy equipment.

Further, the photoelectric device is used to visually detect the deformation state of the O-shaped sealing ring to obtain the performance of the detected O-shaped sealing ring. This detection method needs to disassemble and assemble the O-shaped sealing ring and needs to press the X and Y axes respectively during the detection of the O-shaped sealing ring. Long time occupation of the detection station is not suitable for high-speed line operation, which reduces the practicability of the detection device and affects the detection efficiency.

At this time, the stretching arms move towards each other, and the workpiece to be detected is separated from the stretching protrusions 74. After the second lifting cylinder 8 is lowered, the rotating table 90 is rotated by 90 degrees, so that the workpiece to be detected is synchronously rotated. After the rotation is completed, the second lifting protrusion drives the workpiece to be detected to the position of the stretching protrusion 74. The stretching arms are separated again to complete the sleeving of the workpiece to be detected. The second lifting cylinder 8 is lowered and separated from the position of the stretching arm.

[0076] If the workpiece to be detected is too large or there is a visual obstruction, the adjusting motor 75 is driven to rotate the workpiece to be detected to a certain extent, so that the detection camera 4 can acquire multiple pictures of the workpiece to be detected, and avoid the shooting dead angle caused by the workpiece obstruction.

[0077] The driving frame 51 drives the workpiece to be detected into the second group of detection units for image acquisition detection. After data acquisition, the processor analyzes and judges, and the driving frame 51 drives the strutting arm to the area at the tail end of the detection equipment according to the quality judged by the processor, and puts it into the corresponding discharge channel, releasing the workpiece to be detected to slide into the corresponding collection bin.

[0078] According to actual needs, those skilled in the art can set the moving stretching unit to two groups to form a double module detection according to needs. The two groups of the line changing units move synchronously to ensure the detection rhythm of the detection equipment. At this time, the first moving stretching unit and the second moving stretching unit are respectively arranged on the guide rail 5, so that the first moving stretching unit returns to the position of the first lifting cylinder 6 after the reversing unit takes over the material to be detected, and the subsequent working process is processed by the second moving stretching unit. The first moving stretching unit reciprocates in the interval between the first lifting cylinder 6 and the reversing unit, and the second moving stretching unit reciprocates in the interval between the reversing unit and the collection channel, thereby improving the detection efficiency.

[0079] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims, not the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0080] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description manner of the specification is only for the sake of clarity, those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments that those skilled in the art can understand.
