Description

Technical Field

[0001] The utility model relates to the technical field of machine vision detection, in particular to a detection device. Background Art

[0002] For some cylindrical workpieces, after production is complete, the perimeter and end faces of the workpiece need to be photographed and inspected to determine if the workpiece is qualified. Existing inspection methods generally involve two separate photo inspections: one in which a camera directly photographs the end face of the cylindrical workpiece to determine if the end shape is qualified, and another in which a camera photographs the perimeter of the workpiece to determine if the perimeter is qualified. This type of inspection device requires two steps to complete the inspection of cylindrical workpieces, resulting in low efficiency and the need for more than two cameras, which results in a larger inspection device.

[0003] In view of this, it is necessary to design a detection device to further improve the detection efficiency of cylindrical workpieces and help reduce the size of the detection device.

[0041] Please refer to Figures 1 to 3 The embodiment of the utility model provides a detection device, including: a cylinder 1, a light board 2, a spectrometer 3 and at least three reflectors 4.

[0042] Among them, the cylinder 1 has a through hole 101 and is provided with a detection hole 102 connected to the through hole 101. The cylinder 1 plays the role of supporting the light board 2, the spectrometer 3 and the reflector 4; the light board 2, the spectrometer 3 and at least three reflectors 4 are arranged in intervals in the through hole 101; the light board 2 emits light in the direction of the spectrometer 3.

[0043] The beam splitter 3 is installed at an angle on the light-emitting side of the lamp panel 2, corresponding to the position of the detection hole 102. All reflectors 4 are installed in a circular array around the centerline of the through hole 101, and the detection socket for the cylindrical workpiece 01 is formed between all reflectors 4. The detection camera 5 has its lens facing the detection hole 102.

[0044] The light emitted from the light board 2 passes through the beam splitter 3 and is incident on the mirror surface 42 of the reflector 4. The reflector 4 is used to reflect the peripheral image of the columnar workpiece 01 to the beam splitter 3; the beam splitter 3 reflects the peripheral image of the columnar workpiece 01 and the end face image of the columnar workpiece 01, so that the peripheral image of the columnar workpiece 01 and the end face image of the columnar workpiece 01 are reflected from the detection hole 102 to the detection camera 5.

[0045] In actual inspection, the cylindrical workpiece is directly inserted into the inspection socket. At this time, the end face of one end of the cylindrical workpiece is facing the spectrometer 3, and the reflector 4 reflects the peripheral image of the cylindrical workpiece 01 to the spectrometer 3. The spectrometer 3 can directly reflect the end face and peripheral image to the inspection camera 5, so that the inspection camera 5 can directly take pictures to inspect the end face and the entire peripheral surface of the cylindrical workpiece.

[0046] The detection device of this embodiment, on the one hand, does not need to set up two or more cameras, and the light board 2, the spectrometer 3 and at least three reflectors 4 are all arranged in the cylinder 1, which can make the volume of the entire device smaller, and the detection can be completed by inserting the cylindrical workpiece only once, which is beneficial to improving the detection efficiency of the cylindrical workpiece.

[0047] Optionally, the tail end of the reflector 4 away from the light board 2 is not higher than the end surface of the barrel 1. This can effectively reduce the possibility of damage to the reflector 4 and can help extend the service life of the detection device.

[0048] Optionally, a radiator 6 is installed at one end of the barrel 1, the radiator 6 closes one end of the through hole 101, and the lamp board 2 is attached to the radiator 6. The radiator 6 can dissipate heat for the lamp board 2 to prevent the temperature of the lamp board 2 from being too high.

[0049] Optionally, a fixing column 71 is provided at one end of the through hole 101, and the end of the fixing column 71 is hinged to the back of the reflector 4; an adjustment ring 72 is also slidably installed on the outer periphery of the cylinder 1, and the adjustment ring 72 is connected to a connecting rod 73, and the two ends of the connecting rod 73 are respectively hinged to the reflector 4 and the adjustment ring 72; the adjustment ring 72 can slide along the cylinder 1 to adjust the inclination angle of the reflector 4.

[0050] Specifically, when the tilt angle of the reflector 4 needs to be adjusted, the tilt angle of the reflector 4 can be adjusted by directly sliding the adjustment ring 72. Figure 3 As shown, when the adjustment ring 72 slides to the left, the ends of all reflectors 4 separate from the inner wall of the through-hole 101, thereby bringing the ends of the reflectors 4 near the light board 2 closer to the centerline of the through-hole 101. In this embodiment, the tilt angles of all reflectors 4 can be adjusted simultaneously by simply sliding the adjustment ring 72 to the appropriate position. After adjustment, the adjustment ring 72 is fixed to the barrel 1 by tightening the screws.

[0051] Optionally, the cylinder body 1 is provided with an avoidance groove 103 for avoiding the connecting rod 73. Preferably, the two opposite side walls of the connecting rod 73 are slidably fitted with the two opposite side groove walls of the avoidance groove 103.

[0052] Optionally, the cross section of the through hole 101 is rectangular on a plane perpendicular to the center line of the through hole 101. Preferably, the cross section of the through hole 101 is square.

[0053] Optionally, the reflector 4 includes a triangular prism 41 and a mirror surface 42 disposed on the inclined surface of the triangular prism 41; the first side surface of the triangular prism 41 is in contact with the inner wall of the through hole 101, and the second side surface of the triangular prism 41 is flush with the end surface of the cylinder 1. The triangular prism 41 supports the mirror surface 42, and the inclination angle of the mirror surface 42 is fixed.

[0054] Optionally, the lamp board 2 includes a circuit board and a plurality of lamp beads arranged in an array on the circuit board.

[0055] Optionally, the beam splitter 3 is tilted at 45° and is located directly below the detection camera 5 .

[0056] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
