[0031] See also Figures 1 to 5 The embodiment of the present application provides a protective member, including a brightening portion 100 and a protective portion 200. The protective portion 200 is arranged around the periphery of the brightening portion 100. The brightening portion 100 is provided with an avoidance hole 110 for installing the light strip 10. The roughness of the inner wall surface of the avoidance hole 110 is 5μm to 15μm.

[0032] In the present embodiment, the roughness of the inner wall surface of the avoidance hole 110 is set between 5μm and 15μm, so that the inner wall surface of the avoidance hole 110 can reflect the light irradiated thereon. In this way, when the light strip 10 is set in the avoidance hole 110, the light on the outer edge side of the light strip 10 can be reflected to the middle area of ​​the avoidance hole 110 through the inner wall surface of the avoidance hole 110, thereby realizing the utilization of the light on the outer edge side of the light strip 10, enhancing the focusing and gathering effects, improving the effective brightness of the light strip 10, and increasing the brightness of the light irradiated on the outer surface of the workpiece to be inspected in the middle area of ​​the avoidance hole 110, thereby improving the accuracy and reliability of the appearance inspection results of the workpiece to be inspected. At the same time, the protective part 200 is arranged around the outside of the brightening part 100, and the light strip 10 is arranged in the avoidance hole 110 of the brightening part 100. The mechanical protection of the brightening part 100 can be strengthened by the protective part 200, and the mechanical protection of the light strip 10 can be strengthened by the protective part 200 and the brightening part 100, so as to avoid the occurrence of damage to the light strip 10 due to collision of external components, and extend the service life of the light strip 10. The protective member 20 provided in this example has a simple structure, a strong light gathering and light gathering effect, and can effectively avoid mechanical collision damage to the light strip 10 by external components, thereby improving the irradiation performance and service life of the light strip 10.

[0033] In one example, the brightening part 100 can be a continuum along its circumference, forming a circular member with a certain axial thickness, wherein an axially through avoidance hole 110 is opened in the middle region, and a connecting ring or a sheet-like connecting belt is left at the periphery. In this case, the protective part 200 can also be a continuum along its circumference, forming an annular member with a certain axial thickness, and the annular protective part 200 can be sleeved on the outside of the connecting ring or sheet-like connecting belt of the brightening part 100, so as to achieve mechanical protection of the brightening part 100 and the light strip 10 arranged inside the avoidance hole 110 thereof at least on the periphery of the brightening part 100. The protective part 20 provided in this example has strong overall structural strength and rigidity, and a long service life.

[0034] Of course, in other embodiments, the protection part 200 may also be a plurality of segmented bodies arranged at intervals along its circumference, one end of the segmented body is directly connected to the connecting ring or sheet-shaped connecting belt of the brightness enhancement part 100, and the other end extends radially outwardly along the protection part 20, and the plurality of segmented bodies may be distributed in a zigzag shape on the outer periphery of the brightness enhancement part 100. The protection part 20 provided in this example can save materials, has a light overall weight, and is conducive to a lightweight layout.

[0035] In another example, the inner wall of the protection part 200 can be used to enclose the inner wall surface of the avoidance hole 110, so as to maximize the opening area of ​​the brightening part 100, increase the inner wall surface area of ​​the avoidance hole 110, increase the reflection area of ​​the outer light of the light strip 10, and enhance the focusing and gathering effects of the light strip 10.

[0036] In one example, the material of the brightness enhancement portion 100 and the material of the protection portion 200 can be the same, and both can be made of stainless steel, such as 304 stainless steel, so as to reduce the weight of the protection member 20 while increasing the strength of the protection member 20 and extending the service life of the protection member 20. In this case, the brightness enhancement portion 100 and the protection portion 200 can be integrally formed for easy processing.

[0037] Of course, the materials of the brightening part 100 and the protective part 200 can also be different. The brightening part 100 can be made of a material with better mirror effect, such as stainless steel, to reduce the surface roughness of the inner wall of the avoidance hole 110 thereon, and enhance the reflection effect of the inner wall of the avoidance hole 110 on light; the protective part 200 can be made of a material with certain buffering properties, such as plastic, to buffer and offset the impact force / impact force of external components on the protective part 20, and enhance the protection of the protective part 20.

[0038] like Figure 1 and Figure 2 In a possible implementation, in the axial direction of the protective member 20, the inner wall surface of the avoidance hole 110 includes a first inclined surface 111, an arc surface 112 and a second inclined surface 113 arranged in sequence, and the arc surface 112 protrudes inward from the first inclined surface 111 and the second inclined surface 113.

[0039] In this embodiment, the specific configuration of the avoidance hole 110 is optimized. Specifically, the inner wall of the avoidance hole 110 is configured as a three-section structure including at least a first inclined surface 111, a circular arc surface 112 and a second inclined surface 113. The circular arc surface 112 protrudes inward and can be used to connect the light strip 10. The first inclined surface 111 and the second inclined surface 113 can be inclined curved surfaces or inclined planes. The circular arc surface 112 protrudes outward, which can reflect the light outside the light strip 10 to the middle area of ​​the avoidance hole 110, further enhancing the focusing effect of the protective member 20.

[0040] In a possible implementation, the radial width of the protection portion 200 is 3 mm to 10 mm. This arrangement can avoid the situation where the radial width of the protection portion 200 is too small, making the protection member 20 too thin, causing the protection member 20 to be easily penetrated by external components; or, it can avoid the situation where the radial width of the protection portion 200 is too large, making the protection member 20 too thick, causing the overall weight of the protection member 20 to be too heavy, and the protection member 20 is easy to fall off from the connector 30 that connects it to the specified position of the device, causing safety accidents such as smashing the workpiece to be inspected or the carrier 3. In this example, the radial width of the protection portion 200 is set within a suitable range, which can not only achieve effective protection of the brightening portion 100 and the light strip 10 connected to the avoidance hole 110 of the brightening portion 100, but also make the protection member 20 and the connector 30 firmly connected.

[0041] The thickness of the outer peripheral edge of the brightening portion 100 is increased in the radial direction to strengthen the protection of the brightening portion 100. In one example, the protection portion 200 can be coaxially arranged with the brightening portion 100 to facilitate processing and assembly. Of course, the protection portion 200 can also be non-coaxial with the brightening portion 100. In this case, the protection portion 200 includes a thin section and a thick section, and only one thin section and one thick section can be provided to reduce the overall weight of the protection portion 200. Of course, in other embodiments, multiple thin sections can be provided, and multiple thick sections can be provided, and a thin section and a thick section are staggered to improve the weight uniformity of the protection portion 200 while reducing the overall weight of the protection portion 200, and improve the stability of the protective member 20.

[0042] like Figure 1 , Figure 2 and Figure 4 In a possible implementation, a plurality of connection holes 210 are provided on the protection portion 200 , and the plurality of connection holes 210 are spaced apart and distributed in the circumferential direction of the protection portion 200 , and the connection holes 210 penetrate the protection portion 200 along the axial direction of the protection member 20 .

[0043] In this example, a plurality of connection holes 210 are arranged on the annular protection part 200 and are spaced apart along the circumference thereof. At the same time, a plurality of locking holes are spaced apart along the circumference of the connection piece 30 of the lamp 2, and one locking hole corresponds to one connection hole 210. In this way, fasteners such as screws / bolts can be passed through the connection holes 210 and penetrated into the locking holes to achieve the connection and fastening of the protection part 200 and the connection piece 30. The protection piece 20 provided in this example can achieve the connection of the protection piece 20 and the connection piece 30 at multiple points in the circumferential direction through the plurality of connection holes 210, and the connection and fastening of the two are strong and not easy to loosen.

[0044] To take a step back, even if one or a few of the connecting holes 210 and the locking holes are free from the constraints of fasteners such as screws / bolts, it will not affect the normal use of the lamp 2, and the lamp 2 is more usable.

[0045] like Figure 1 , Figure 3 and Figure 4 In a possible implementation manner, the protection portion 200 is further provided with a plurality of connection grooves 220 , one connection groove 220 corresponds to one connection hole 210 , and the connection groove 220 is located on the first surface 201 of the protection portion 200 .

[0046] In this example, a plurality of connecting grooves 220 are arranged on the annular protective portion 200 and are spaced apart along its circumference. One connecting groove 220 corresponds to one connecting hole 210, which is used to receive the ends of fasteners such as screws / bolts, so as to prevent the ends of fasteners such as screws / bolts from extending out of the first surface 201 of the protective member 20 and scratching the workpiece to be inspected on the carrier plate under the lamp 2, thereby improving the mechanical protection of the workpiece to be inspected.

[0047] In one example, the connection groove 220 can be opened from the edge of the protection part 200 to the inside thereof to facilitate processing. Of course, in other embodiments, the connection groove 220 can also be opened at a position close to the edge of the protection part 200. The specific opening position of the connection groove 220 is not limited here, as long as its axial projection area can completely cover the axial projection area of ​​the connection hole 210.

[0048] like Figures 1 to 6 In a possible implementation, a plurality of limiting notches 230 are provided on the protection portion 200 , and the plurality of limiting notches 230 are spaced apart and distributed in the circumferential direction of the protection portion 200 , and the limiting notches 230 extend along the axial direction of the protection member 20 and penetrate the protection portion 200 .

[0049] In this example, a plurality of limiting notches 230 are arranged on the annular protection part 200 at intervals along the circumference thereof. The limiting notches 230 may be semicircular notches opening outward, which are located at the edge of the protection part 200 and may be opened from the edge of the protection part 200 to the inside thereof for easy processing. The limiting notches 230 may be used to avoid the workpiece to be detected or the protrusion on the carrier 3 located below the protection part 20, so as to avoid the workpiece to be detected or the protrusion colliding with the protection part 20 when the carrier 3 is moved, thereby damaging the workpiece to be detected, the carrier 3 and the protection part 20, which is beneficial to prolonging the service life of the carrier 3 and the protection part 20 and enhancing the protection of the workpiece to be detected. In addition, the limiting notch 230 may also form a limit with the protrusion on the carrier 3, so as to prevent the protection part 20 from rotating around its axial direction, thereby improving the position stability of the light strip 10 / light source, improving the stability and uniformity of the light irradiated on the surface of the workpiece to be detected, improving the lighting effect of the lamp 2 on the workpiece to be detected, and improving the accuracy and reliability of the appearance inspection results.

[0050] like Figure 1 , Figure 3 and Figure 4 In a possible implementation manner, a limiting groove 240 is provided on the second surface 202 of the protection portion 200 , the limiting groove 240 penetrates the protection portion 200 in the radial direction of the protection member 20 , and the limiting groove 240 overlaps with the limiting notch 230 .

[0051] In this example, a limiting groove 240 is provided on the second surface 202 of the protecting portion 200 and penetrates the protecting member 20 radially. At the same time, a limiting protrusion extending radially is provided on the side of the connecting member 30 of the lamp 2 facing the protecting member 20. The outward portion of the limiting groove 240 covers the limiting notch 230 and forms an axial hollow area together with the limiting notch 230 to facilitate the penetration of the protrusion on the carrier 3 located on the first surface 201 side of the protecting portion 200 or the workpiece to be detected to achieve avoidance and limiting. The bottom of the inward portion of the limiting groove 240 is lower than the brightening portion 100, so that the outer wall of the brightening portion 100 can be used to limit the inner side of the limiting protrusion on the connecting member 30. In this way, when the connector 30 overlaps and is connected above the protective member 20, the limiting protrusion is inserted into the limiting groove 240, which can effectively prevent the protective member 20 and the connector 30 from twisting, thereby improving the connection tightness and stability of the protective member 20 and the connector 30. In addition, the limiting protrusion on the connector 30 and the limiting groove 240 on the protective member 20 can also be used to achieve rapid alignment and assembly of the connector 30 and the protective member 20, thereby improving assembly efficiency.

[0052] In one example, two or more limit grooves 240 are provided, and the following description is made by taking two limit grooves 240 as an example. The two limit grooves 240 are arranged opposite to each other and are located on a straight line with the same diameter of the protection part 200, so that the assembly accuracy of the protection member 20 and the connecting member 30 can be further improved, and the anti-twisting strength between the protection member 20 and the connecting member 30 can be strengthened.

[0053] like Figure 1 , Figure 3 , Figure 4 and Figure 5 In a possible implementation, an arc-shaped recessed groove 250 is further provided on the second surface 202 of the protection portion 200 , and in the axial direction of the protection member 20 , the bottom wall of the arc-shaped recessed groove 250 is lower than the bottom wall of the limiting groove 240 .

[0054] In this example, an arc-shaped groove 250 is provided on the second surface 202 of the protection part 200. One end of the arc-shaped groove 250 can be connected to one of the limiting grooves 240, and the other end is spaced from the connecting hole 210 and the connecting groove 220. It is a poor arc groove section, which can reduce the overall weight of the protection part 20, save raw materials, and facilitate subsequent transfer and storage. At the same time, an arc-shaped notch corresponding to the arc-shaped groove 250 is provided on the connecting part 30 of the lamp 2. The shape and size of the arc-shaped notch are roughly the same as the arc groove, so that after the protection part 20 is connected to the connecting part 30, the arc-shaped groove 250 is connected to the arc-shaped notch to form an escape zone located above the protection part 200. The escape zone can avoid the downward protruding parts of the appearance inspection device located above the protection part 200, thereby improving the mechanical protection of the protection part 20.

[0055] Second, as Figures 2 to 5 The present application also provides a lamp, including a lamp strip 10 and the protective member 20 as described above, wherein the lamp strip 10 is arranged around the inner wall surface of the avoidance hole 110 of the protective member 20 .

[0056] This example provides a lamp 2 that can achieve both a focusing effect and protection of the periphery of a light strip 10. The lamp 2 is configured as a composite component that includes at least a light strip 10 and a protective member 20. The light strip 10 can be an LED light strip 10, which has a certain degree of flexibility and can be wound into a ring shape. A plurality of lamp beads are arranged on the light strip 10. By increasing the number of lamp beads, the overall light brightness of the light strip 10 can be increased, thereby improving the accuracy and reliability of subsequent appearance inspections. The specific structure of the protective member 20 refers to the above-mentioned embodiment. Since the lamp 2 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. The lamp 2 provided in this example has a simple structure, high integration, good focusing effect, is easy to fill in light, and is conducive to improving the efficiency of subsequent inspections; moreover, it is not easily damaged or crashed by external parts, and has a long service life.

[0057] In a possible implementation, the lamp 2 further includes a connector 30, which is disposed on the second surface 202 of the protective member 20. The connector 30 may be an annular sheet metal member, on which a hollow hole is provided, and the hollow hole corresponds to the avoidance hole 110 on the protective member 20, so that the subsequent detection member 1 can detect the workpiece to be detected located below the lamp 2 through the hollow hole and the avoidance hole 110; the size of the hollow hole may be slightly smaller than the size of the avoidance hole 110, so that the inner ring side of the connector 30 can cover the top of the light strip 10, thereby achieving mechanical protection for the top of the light strip 10. In this way, the overall rigidity of the lamp 2 can be enhanced by the connector 30, thereby achieving protection for the top of the light strip 10; and the lamp 2 can be connected to a designated device by the connector 30, thereby avoiding damage to the light strip 10 and the protective member 20, thereby extending the service life of the lamp 2.

[0058] Thirdly, Figure 6 The present application also provides an appearance inspection device, including an inspection member 1, a lamp 2 as described above, and a carrier 3 arranged in sequence from top to bottom, wherein a plurality of workpieces to be inspected are loaded on the carrier 3, the lamp 2 is used to increase the brightness of the workpieces to be inspected, and the inspection member 1 is used to inspect the appearance quality of the workpieces to be inspected.

[0059] This example provides an appearance inspection device with a more concentrated light source and uniform light brightness. The appearance inspection device is configured to include at least a detection part 1, a lamp 2 and a carrier 3. The detection part 1 can be an industrial camera for capturing the appearance image of the workpiece to be inspected; the lamp 2 is used to provide light to the workpiece to be inspected on the carrier 3 to improve the clarity and integrity of the photographing of the detection part 1; the carrier 3 can be a carrier plate, which is provided with multiple receiving stations on which multiple workpieces to be inspected can be placed. The appearance inspection device provided in this example can detect the surface details and defects of the workpiece to be inspected more accurately, can effectively reduce bad misjudgments, improve inspection efficiency, save inspection costs, and enhance the competitive advantage of products.

[0060] In addition, the specific structure of the lamp 2 refers to the above embodiments. Since the appearance inspection device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0061] In one example, the carrier 3 can be set on a movable rail. In this way, the appearance inspection of different workpieces to be inspected can be achieved by moving the position of the carrier 3, thereby realizing batch appearance inspection of multiple workpieces to be inspected, with high inspection efficiency, high accuracy of inspection results, and strong reliability.
