After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value was finally created.

[0046] Please refer to Figures 1 to 3 This utility model embodiment provides an easily detachable ring light source, including a connecting cylinder 1, a first ring light-emitting component 2, and a connecting fixing component 3.

[0047] The connecting cylinder 1 has a threaded connection part 11 at one end for threaded connection with the lens 6, and an insertion hole 12 at the other end; the first annular light-emitting component 2 includes a first cylindrical member 21 for insertion connection with the insertion hole 12, the depth of insertion of the first cylindrical member 21 into the insertion hole 12 is adjustable, and the inner hole of the connecting cylinder 1 is coaxial with the inner hole of the first cylindrical member 21; the connecting fixing member 3 passes through the connecting cylinder 1 and connects to the first cylindrical member 21, so that the connecting cylinder 1 and the first cylindrical member 21 are relatively fixed.

[0048] In this embodiment, compared to the prior art, a connecting cylinder 1 is added. The connecting cylinder 1 can be fixedly connected to the lens 6 through a threaded connection part 11, and the other end of the connecting cylinder 1 forms an insertion hole 12 for connecting to the first annular light-emitting component 2. The insertion depth of the first cylindrical member 21 into the insertion hole 12 is adjustable, thereby fixing the first annular light-emitting component 2 at different heights and changing the relative distance between the first annular light-emitting component 2 and the lens 6. In addition, after the position of the first cylindrical member 21 is adjusted, the connecting fixing member 3 can fix the first cylindrical member 21 to the connecting cylinder, thereby maintaining the first cylindrical member 21 at the current height.

[0049] Optionally, the first annular light-emitting component 2 further includes a first light-emitting plate 22, which emits light along the center line of the first cylindrical member 21 in a direction away from the lens 6. The first light-emitting plate 22 is installed on the end face of the first cylindrical member 21 away from the connecting cylinder 1. The first light-emitting plate 22 surrounds the inner hole of the first cylindrical member 21.

[0050] In this embodiment, the first light-emitting plate 22 is used to emit light onto the workpiece under test, thereby illuminating the top surface of the workpiece. The workpiece under test can be a chip or other small-volume workpiece. The image of the workpiece under test enters the camera under test through the inner hole of the first cylindrical member 21, the inner hole of the connecting cylinder 1, and the lens 6.

[0051] Optionally, the easily detachable ring light source also includes a second ring light-emitting component 4; the second ring light-emitting component 4 includes a second cylindrical component 41 that is detachably connected to the first cylindrical component 21, and a second light-emitting plate 42 installed at the bottom of the second cylindrical component 41; the inner hole of the first cylindrical component 21 and the inner hole of the second cylindrical component 41 are coaxial.

[0052] The light emitted by the second light-emitting board 42, when superimposed on the light emitted by the first light-emitting board 22, can better illuminate the workpiece under test and improve the accuracy of subsequent inspections.

[0053] Optionally, the first light-emitting plate 22 is annular and perpendicular to the inner hole of the first cylindrical member 21; the second light-emitting plate 42 is conical and emits light in a direction away from the first cylindrical member 21, and the center line of the conical shape coincides with the center line of the second cylindrical member 41.

[0054] In this embodiment, the first light-emitting plate 22 is used to illuminate the top surface of the workpiece to be tested, while the second light-emitting plate 42 emits light at an angle to illuminate the outer periphery of the workpiece to be tested, thereby illuminating the top and outer periphery of the entire workpiece more completely, so that the subsequent camera 5 can more accurately detect surface defects or other defects of the workpiece to be tested.

[0055] Optionally, the top of the second cylindrical member 41 is provided with an insertion mounting groove 4101 for connecting the second cylindrical member 41, and a first annular diffuser plate 23 is installed at the bottom of the insertion mounting groove 4101. The first annular diffuser plate 23 can homogenize the light, making the light illuminating the top of the workpiece to be measured more uniform.

[0056] Optionally, a second annular diffuser plate 43 is also connected to the bottom end of the second cylindrical member 41; the second annular diffuser plate 43 has a conical portion parallel to the second light-emitting plate 42 and a connecting portion connecting the conical portion. The second annular diffuser plate 43 can homogenize the light emitted by the second light-emitting plate 42, making the light illuminating the outer periphery of the workpiece to be measured more uniform.

[0057] Optionally, the connecting cylinder 1 is provided with a through-hole adjustment vertical groove 101; the connecting fastener 3 passes through the adjustment vertical groove 101 and is threadedly connected to the first cylindrical member 21, and the connecting fastener 3 can slide along the adjustment vertical groove 101 to adjust the position of the first cylindrical member 21. Specifically, since the connecting fastener 3 is threadedly connected to the first cylindrical member 21 through the adjustment vertical groove 101, the relative position of the connecting fastener 3 and the first cylindrical member 21 cannot be adjusted. At this time, the connecting fastener 3 can be loosened, and then the depth of the first cylindrical member 21 inserted into the insertion hole 12 can be adjusted. At this time, the connecting fastener 3 slides relative to the adjustment vertical groove 101. Finally, the connecting fastener 3 is tightened, so that the connecting cylinder 1 and the first cylindrical member 21 are fixed to each other, and the height of the first annular light-emitting component 2 is adjusted relative to the lens 6.

[0058] Optionally, the connecting fastener 3 is a wing-threaded fastener. The operator can directly loosen or tighten the wing-threaded fastener manually to adjust the height of the first annular light-emitting component 2.

[0059] Optionally, the first annular light-emitting component 2 includes an annular light panel and an annular array of LEDs mounted on the annular light panel.
