Description

Technical Field

[0001] This utility model relates to the field of light source technology, and in particular to a detection light source. Background Technology

[0002] With social progress and the improvement of people's living standards, the requirements for product appearance are also increasing. In order to ensure the appearance quality of products, appearance inspection is required before products leave the factory.

[0003] Existing detection light sources generally only have one light emission effect, and can usually only be used to detect a specific product. Their application range is small and they are difficult to adapt to the detection needs of products with many specifications. Therefore, multiple detection light sources are usually set up on the detection line to meet the actual detection needs.

[0004] Therefore, it is necessary to design a detection light source to provide different light output effects.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0006] This invention provides a detection light source to offer different light emission effects.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A detection light source, comprising:

[0009] A transparent diffuser plate has a plurality of through-holes arranged in a circumferential array. The through-holes include sequentially connected circular holes and conical holes, and the center lines of the corresponding connected circular holes and conical holes coincide. The diameter of the conical hole is smaller the closer it is to the circular hole.

[0010] The light panel is fixedly connected to the transparent diffuser plate, has a through hole matching the circular hole, and is provided with a ring light group surrounding the through hole to emit light to the transparent diffuser plate;

[0011] Each of the conical holes has a different taper, and the outer peripheral surface of the transparent diffuser plate, the bottom surface away from the lamp plate, and the inner surface of the circular hole are all provided with a light-shielding coating.

[0012] Optionally, the detection light source further includes a housing having a mounting groove, in which the transparent diffuser plate and the lamp plate are both mounted;

[0013] The lamp plate is sandwiched between the transparent diffuser plate and the bottom wall of the mounting groove, and the housing is provided with an observation hole that matches the through hole.

[0014] Optionally, the lengths of two adjacent circular holes are different.

[0015] Optionally, the lengths of the different circular holes gradually increase in a clockwise direction around the center line of the transparent diffuser plate.

[0016] Optionally, the light panel further includes a circuit board, and the ring light assembly is mounted on the circuit board.

[0017] Optionally, the top of the transparent diffuser plate is provided with a receiving groove, and the ring light assembly is located in the receiving groove;

[0018] The circuit board is attached to the top surface of the transparent diffusion plate.

[0019] Optionally, the detection light source also includes a rotating device mounted on one side of the top of the housing to drive the housing to rotate around the centerline of the transparent diffuser plate.

[0020] Optionally, all the circular holes have the same diameter.

[0021] Optionally, the ring-shaped light assembly includes a plurality of LED beads arranged in a circumferential array around the corresponding through hole.

[0022] Optionally, the circular hole, the through hole, and the observation hole have the same diameter.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The detection light source provided by this utility model allows different through-holes to face the product to be inspected by rotating the transparent diffuser plate. The light emitted by the ring lamp group passes through the transparent diffuser plate and is emitted from the hole wall of the conical hole, illuminating the surface of the workpiece to be inspected. Since the taper of different conical holes is different, the light emission effect is also different. Therefore, the light emission effect can be changed directly by rotating the transparent diffuser plate, so that the light emission effect of the detection light source is more varied.

[0025] This invention has other features and advantages that will be apparent from or will be set forth in detail in the accompanying drawings and the following detailed description, which together serve to explain the particular principles of this invention. Attached Figure Description

[0042] Please refer to Figures 1 to 4 This utility model embodiment provides a detection light source, including: a transparent diffuser plate 1, which has a plurality of through detection holes 11 arranged in a circumferential array. The through detection holes 11 include circular holes 101 and conical holes 102 connected in sequence, and the center lines of the corresponding circular holes 101 and conical holes 102 coincide; the diameter of the conical holes 102 is smaller as it is closer to the circular holes 101; and a lamp plate 2, which is fixedly connected to the transparent diffuser plate 1, has through holes 201 that match the circular holes 101, and is provided with an annular lamp group 21 surrounding the through holes 201 to emit light to the transparent diffuser plate 1.

[0043] Each of the conical holes 102 has a different taper, and a light-shielding coating is provided on the outer peripheral surface of the transparent diffuser plate 1, the bottom surface away from the lamp plate 2, and the inner surface of the circular hole 101.

[0044] Specifically, by rotating the transparent diffuser plate 1, different through-holes 11 are positioned facing the product to be inspected. The light emitted from the ring lamp assembly 21 passes through the transparent diffuser plate 1 and exits from the wall of the conical hole 102, illuminating the surface of the workpiece to be inspected. Since the taper of the different conical holes 102 is different, the light emission effect is also different. Therefore, by directly rotating the transparent diffuser plate 1, different through-holes 11 can be positioned facing the workpiece to be inspected, thereby changing the light emission effect and making the light emission effect of the inspection light source more varied.

[0045] It should be noted that different conical holes 102 have different light emission effects due to the different inclination angles and total areas of the hole walls.

[0046] Optionally, the detection light source also includes a housing 3, which has a mounting groove 31 in which the transparent diffuser plate 1 and the lamp plate 2 are both installed. The lamp plate 2 is sandwiched between the transparent diffuser plate 1 and the bottom wall of the mounting groove 31, and the housing 3 is provided with an observation hole 301 matching the through hole 201. Generally, the lamp plate 2 is fixed to the bottom wall of the mounting groove 31, and the transparent diffuser plate 1 is fixedly connected to the groove wall of the mounting groove 31. The housing 3 serves to support the transparent diffuser plate 1 and the lamp plate 2, and can prevent the light from leaking out of the ring lamp assembly 21.

[0047] Optionally, the lengths of two adjacent circular holes 101 are different, thereby making the difference in hole area between different conical holes 102 even greater.

[0048] Optionally, the lengths of different circular holes 101 gradually increase in a clockwise direction around the center line of the transparent diffuser plate 1, so that the light emission effect at the bottom of different conical holes 102 can be gradually changed.

[0049] Optionally, the lamp board 2 also includes a circuit board 22, on which the ring lamp assembly 21 is mounted. The circuit board 22 supplies power to the ring lamp assembly 21 and controls the ring lamp assembly 21 to turn on or off.

[0050] Optionally, a receiving groove 12 is provided on the top of the transparent diffuser plate 1, and the ring light group 21 is located in the receiving groove 12; the circuit board 22 is attached to the top surface of the transparent diffuser plate 1. The receiving groove 12 allows the light emitted by the ring light group 21 to enter the transparent diffuser plate 1 better.

[0051] Optionally, the detection light source also includes a rotating device 4 mounted on one side of the top of the housing 3 to drive the housing 3 to rotate around the centerline of the transparent diffuser plate 1. The rotating device 4 can be a rotary cylinder, a rotary motor, or other drive device capable of driving the housing 3 to rotate.

[0052] Optionally, all the holes 101 have the same diameter.

[0053] Optionally, the ring-shaped light assembly 21 includes a plurality of LED beads, which are arranged in a circular array around the corresponding through hole 201.

[0054] Optionally, the diameters of the circular hole 101, the observation hole 301, and the through hole 201 are the same.

[0055] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
