Description

Technical Field

[0002] The detection of existing workpieces is generally completed by a vision detection device. The vision detection device specifically includes a detection camera module and a light source module. Among them, the light source module is used to provide illumination light to the measured surface of the workpiece, and the detection camera module is used to obtain the light reflected from the measured surface to form an image.

[0003] Since in the vision detection process, the detection camera is generally installed in the longitudinal position of the light source module, that is, the detection camera is located above or below the light source module, which makes the space occupied by the vision detection device relatively large, and it is often impossible to complete the vision detection work of the workpiece due to interference with other mechanisms, bringing certain troubles to users.

[0008] A placement position for placing a workpiece is arranged at the central position of the housing;

[0009] The light source body is installed on the housing and is located on the side of the placement position. The beam splitter is located between the light source body and the placement position and is fixed on the housing;

[0010] The reflecting mirror is fixed on the housing and is located below the beam splitter. The reflecting surface of the reflecting mirror faces the beam splitter;

[0011] The detection camera is fixed on the housing and faces the reflecting surface of the reflecting mirror;

[0012] The light emitted by the light source body passes through the beam splitter and irradiates the workpiece on the placement position. The light reflected by the workpiece is reflected by the beam splitter to the reflecting surface of the reflector, and the reflecting surface of the reflector reflects the light to the detection camera.

[0013] Optionally, an absorbing plate is arranged above the beam splitter.

[0014] Optionally, the beam splitter is parallel to the reflector.

[0015] Optionally, the number of the light source modules is four;

[0016] The four light source modules are respectively located on the four sides of the placement position.

[0019] Optionally, the light source body is an LED light board.

[0020] Optionally, the LED light board includes a PCB board and LED lamp beads electrically connected to the PCB board.

[0021] It can be seen from the above technical solutions that the embodiments of the present utility model have the following advantages:

[0022] In the compact vision detection device of this embodiment, the light emitted by the light source body passes through the beam splitter and irradiates the workpiece on the placement position. The light reflected by the workpiece is reflected by the beam splitter to the reflecting surface of the reflector, and the reflecting surface of the reflector reflects the light to the detection camera. Through the above design, since the light reflected from the workpiece is reflected twice successively through the beam splitter and the reflector, forming a Z-shaped optical path, therefore, the camera in this embodiment can be placed horizontally, effectively saving the longitudinal space of the entire vision detection device, being beneficial to improving the compactness of the entire vision detection device, avoiding interference with other mechanisms during the detection process, and ensuring the smooth progress of the detection work of the workpiece.
