[0041] In view of the defects existing in the above-mentioned existing detection devices, the applicant, based on years of rich practical experience and professional knowledge in the design and manufacture of such products, and in combination with the application of scientific principles, actively conducts research and innovation in the hope of creating a technology that can solve the defects in the existing technology and make the detection device more practical. After continuous research, design, and repeated trial production of samples and improvements, the present utility model with practical value has finally been created.

[0042] Please refer to Figures 1 to 2 , an embodiment of the present utility model provides a detection device, including: a support base 1 for support; a coaxial light source 2 slidably mounted on one side of the top of the support base 1 and slidable along a set direction to adjust the position. The coaxial light source 2 can slide along the support base 1 to adjust its own position to meet the position requirements of detection. A detection camera 3 is mounted on one side of the top of the coaxial light source 2 and fixedly connected to the coaxial light source 2 for taking pictures and detecting a workpiece 100 through the coaxial light source 2; a reflector 4 is mounted on one side of the support base 1 for reflecting the workpiece image through the coaxial light source 2 into the detection camera 3. The setting of the reflector 4 can avoid the situation of friction caused by the too-close distance between the workpiece 100 and the support base 1, and facilitate the loading and unloading of the workpiece 100 more conveniently. At least two filter plates 5 are arranged in a row along the set direction between the reflector 4 and the coaxial light source 2. The filter plates 5 are used to filter the light emitted by the coaxial light source 2, and the colors of two adjacent filter plates 5 are different.

[0043] Specifically, for example, the colors of the two filter plates 5 are a red filter plate and a green filter plate respectively. When green light is required to irradiate on the surface of the workpiece 100, the coaxial light source 2 is slid to a suitable position, that is, directly above the green filter plate. At this time, the detection camera 3 also moves to a suitable position along with the coaxial light source 2 to take pictures of the workpiece 100; when red light is required to irradiate on the surface of the workpiece 100, the coaxial light source 2 is slid to a suitable position, that is, directly above the red filter plate. At this time, the detection camera 3 also moves to a suitable position along with the coaxial light source 2 to take pictures of the workpiece 100. That is, the detection device of the present utility model can detect workpieces 100 with at least two different surface colors.

[0044] The detection device in this embodiment can detect more types of workpieces 100, such as workpieces 100 with different surface colors, and the detection range is relatively larger. It should also be supplemented that the placement position of the workpiece 100 needs to be adjusted adaptively under different illumination colors.

[0045] Optionally, a slide rail <61> is provided on the support base <1>. A sliding seat <62> is slidably mounted on the slide rail <61>. The coaxial light source <2> is fixedly connected to the sliding seat <62>. The coaxial light source <2> includes a housing <21>, a lamp board <22> installed in the housing <21>, and a beam splitter <23> installed in the housing <21>. The mirror surface of the beam splitter <23> is parallel to the beam splitter <23>. The beam splitter <23> is disposed directly below the detection camera <3>, and a detection hole is provided in the housing <21> corresponding to the detection camera <3>. The beam splitter <23> is located in the detection hole. Specifically, the lamp board <22> emits light, which is directed at the filter <5> after passing through the beam splitter <23>. The light passes through the filter <5> and is then directed at the workpiece <100> by the reflector <4>. In addition, by providing the slide rail <61>, the sliding adjustment of the coaxial light source <2> is simpler and it is easier to adjust the position.

[0046] Optionally, a diffuser plate <24> is also installed in the housing <21>. The diffuser plate <24> is installed between the lamp board <22> and the beam splitter <23>. The diffuser plate <24> is used to homogenize the light and improve the light output uniformity.

[0047] Optionally, the filter <5> is fixedly connected to the support base <1>. The position of the filter <5> does not need to be adjusted, avoiding the filter <5> from becoming tilted due to vibration or other reasons, and can well maintain the installation stability of the filter <5>.

[0048] Optionally, a telescopic device <7> for pushing the coaxial light source <2> to slide along the slide rail <61> is also installed on the support base <1>. The telescopic shaft of the telescopic device <7> is connected to the sliding seat <62>. Specifically, in this embodiment, the position of the coaxial light source <2> is adjusted by the telescopic device, and the coaxial light source <2> is controlled to be in a suitable position. Specifically, the telescopic device controls the position of the coaxial light source <2> by controlling the extension length of the telescopic shaft.

[0049] Optionally, the body of the telescopic device <7> and the reflector <4> are installed on opposite sides of the support base <1>. The body of the telescopic device <7> is hinged to the support base <1>, and the telescopic shaft is hinged to the sliding seat <62>. Specifically, as Figure 3 , this can vacate the position at the top of the support base <1>, so that the coaxial light source <2> will not collide with the body of the telescopic device <7>, which is beneficial to reducing the height of the entire device.

[0050] Optionally, a support rod <8> is connected to the top of the housing <21>. The detection camera <3> is installed on the support rod <8>.

[0051] Optionally, an adhesive layer <9> is provided on the side surface of the support base <1>. The reflector <4> is adhered to the adhesive layer <9>.

[0052] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as the direct or indirect implementation of the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
