[0029] It should be noted that, for the convenience of explanation, in the embodiments of the present application, the same figure marks represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0030] The circuit board is drilled with a drilling machine, which needs to be used in conjunction with a feeder. The feeder is used to temporarily store the workpiece to be processed and transfer the workpiece to the drilling machine for loading. The thickness of the workpiece to be processed is closely related to the depth of the drilling machine. However, the existing drilling machine lacks a device to detect the thickness of the workpiece to be processed, which affects the drilling accuracy of the drilling machine.

[0031] See also Figure 1 and Figure 2 The embodiment of the present application provides a detection device 100, which is applied to processing equipment. The processing equipment is used to process a workpiece to be processed. The detection device 100 includes a light source 10, a first light receiver 20 and a second light receiver 30. The light source 10 is used to emit detection light toward the workpiece to be processed; the first light receiver 20 is used to receive the detection light reflected by the workpiece to be processed; the second light receiver 30 is used to receive the detection light reflected by the workpiece to be processed. The first light receiver 20 cooperates with the second light receiver 30 to detect the thickness of the workpiece to be processed and whether the workpiece to be processed is present.

[0032] The processing equipment of the embodiment of the present application can be, but is not limited to, a circuit board or circuit board drilling equipment or punching equipment. The processing equipment includes a loading device and a processing machine. The loading device is used to temporarily store the workpiece to be processed and transfer the workpiece to the processing machine. The processing machine is used to perform drilling and other processing on the workpiece to be processed. The detection device 100 is arranged on the processing machine and is used to detect the thickness of the workpiece to be processed on the processing machine and whether the processing machine has the workpiece to be processed.

[0033] Optionally, the workpiece to be processed may be, but is not limited to, at least one of a circuit board, a printed circuit board, and the like.

[0034] Optionally, the light source 10 may be, but is not limited to, at least one of a light emitting diode light source (LED light source for short), a Micro LED light source, a Mini LED light source, a laser light source, and the like.

[0035] Optionally, the first light receiver 20 may be, but is not limited to, a photoelectric detector (Optoelectronic Detector, PD for short).

[0036] Optionally, the second optical receiver 30 may be, but is not limited to, a photoelectric detector (Optoelectronic Detector, PD for short).

[0037] The detection device 100 of the embodiment of the present application includes a light source 10, a first light receiver 20 and a second light receiver 30, wherein the light source 10 is used to emit detection light toward the workpiece to be processed; the first light receiver 20 is used to receive the detection light reflected by the workpiece to be processed; the second light receiver 30 is used to receive the detection light reflected by the workpiece to be processed, and the first light receiver 20 cooperates with the second light receiver 30 to detect the thickness of the workpiece to be processed and whether the workpiece to be processed exists. The present application detects the detection light reflected by the workpiece to be processed through the cooperation of the first light receiver 20 and the second light receiver 30, so that the thickness of the workpiece to be processed and whether the workpiece to be processed is set on the processing machine can be determined based on the signal of the detected detection light. When applied to processing equipment, the drilling or punching depth of the workpiece to be processed can be more accurately controlled, thereby improving the processing accuracy of the workpiece to be processed and improving the processing yield of the workpiece to be processed.

[0038] Please see again Figure 2 In some embodiments, the detection device 100 further includes a package 40, the package 40 having a preset surface 41, the light emitting light source 10, the first light receiver 20 and the second light receiver 30 are all embedded in the package 40 and exposed on the preset surface 41, the light emitting light source 10, the first light receiver 20 and the second light receiver 30 are arranged in sequence at intervals, and the light emitting light source 10 is arranged to be inclined toward the first light receiver 20 and the second light receiver 30 respectively.

[0039] Optionally, the package 40 may be made of, but not limited to, a resin material. The package 40 may be formed by injection molding. When the package 40 is formed, the light source 10, the first light receiver 20, and the second light receiver 30 are packaged together at the same time.

[0040] It can be understood that the package 40 has a first penetration hole 42, a second penetration hole 43 and a third penetration hole 44, and the first penetration hole 42, the second penetration hole 43 and the third penetration hole 44 respectively penetrate the preset surface 41, the first penetration hole 42 is used to set the light source 10, the second penetration hole 43 is used to set the first light receiver 20, and the third penetration hole 44 is used to set the second light receiver 30.

[0041] It can be understood that the light source 10 is tilted toward the direction close to the first light receiver 20 and the second light receiver 30, so that the detection light is emitted toward the direction close to the first light receiver 20 and the second light receiver 30. The first light receiver 20 is tilted toward the direction close to the light source 10, and the second light receiver 30 is tilted toward the direction close to the light source 10, so as to receive the detection light emitted by the light source 10.

[0042] In this embodiment, the light source 10, the first light receiver 20 and the second light receiver 30 are arranged in sequence at intervals, and the light source 10 is arranged to be inclined toward the first light receiver 20 and the second light receiver 30 respectively. This is beneficial for the first light receiver 20 and the second light receiver 30 to receive the detection signal, and can make the arrangement of the light source 10, the first light receiver 20 and the second light receiver 30 more compact, and the detection device 100 more miniaturized.

[0043] In some embodiments, the light source 10 has a light emitting surface 11 , and the angle α between the light emitting surface 11 and the preset surface 41 is in the range of 40°≤α≤50°.

[0044] It should be noted that, when the detection device 100 is in use, the light emitting surface 11 faces the workpiece to be processed.

[0045] It can be understood that the light source 10 emits the detection light from the light emitting surface 11. It should be noted that the emission direction of the detection light is perpendicular to the light emitting surface 11.

[0046] It can be understood that the angle between the detection light and the preset surface 41 ranges from 40° to 50°. The angle between the detection light and the preset surface 41 and the angle α between the light emitting surface 11 and the preset surface 41 are complementary angles. For example, when the angle α between the light emitting surface 11 and the preset surface 41 is 40°, the angle between the detection light and the preset surface 41 is 50°. For another example, when the angle α between the light emitting surface 11 and the preset surface 41 is 45°, the angle between the detection light and the preset surface 41 is 45°. For another example, when the angle α between the light emitting surface 11 and the preset surface 41 is 50°, the angle between the detection light and the preset surface 41 is 40°.

[0047] Specifically, the angle α between the light emitting surface 11 and the preset surface 41 may be, but is not limited to, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, etc. If the angle α between the light emitting surface 11 and the preset surface 41 is too small, the angle between the detection light and the preset surface 41 is too large, and the distance between the first light receiver 20 and the second light receiver 30 and the light source 10 is too close, which is not conducive to the arrangement of the first light receiver 20, the second light receiver 30 and the light source 10. In addition, if the angle α between the light emitting surface 11 and the preset surface 41 is too small, the detection device 100 needs to be set at a position far away from the workpiece to be processed in order to detect the workpiece to be processed, and the light intensity of the detection light is easily weakened during the transmission process, which reduces the detection light detected by the first light receiver 20 and the second light receiver 30. The signal strength of the detection light reduces the detection sensitivity of the detection device 100; if the angle α between the light emitting surface 11 and the preset surface 41 is too large, the angle between the detection light and the preset surface 41 is too small, and the first light receiver 20 and the second light receiver 30 need to be set at a position far away from the light source 10 to detect the signal of the detection light, which is not conducive to the miniaturization of the detection device 100. In addition, it will also increase the transmission path of the detection light, reduce the light intensity of the detection light, reduce the signal strength of the detection light detected by the first light receiver 20 and the second light receiver 30, and reduce the detection sensitivity of the detection device 100.

[0048] In some embodiments, the first light receiver 20 has a first receiving surface 21 , and the angle β between the first receiving surface 21 and the preset surface 41 is in the range of 40°≤β≤50°.

[0049] It should be noted that, when the detection device 100 is in use, the first receiving surface 21 faces the workpiece to be processed.

[0050] Optionally, the first receiving surface 21 is used to receive the detection light reflected by the workpiece to be processed.

[0051] It can be understood that the first light receiver 20 receives and senses the detection light through the first receiving surface 21 .

[0052] Specifically, the angle β between the first receiving surface 21 and the preset surface 41 may be, but is not limited to, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, etc. If the angle β between the first receiving surface 21 and the preset surface 41 is too small, the distance between the first light receiver 20 and the second light receiver 30 and the light source 10 is too close, which is not conducive to the arrangement of the first light receiver 20, the second light receiver 30 and the light source 10. In addition, if the angle β between the first receiving surface 21 and the preset surface 41 is too small, the detection device 100 needs to be set at a position far away from the workpiece to be processed in order to detect the workpiece to be processed, and the light intensity of the detection light is easily weakened during the transmission process, which reduces the signal intensity of the detection light detected by the first light receiver 20 and the second light receiver 30, and reduces the detection sensitivity of the detection device 100; if the angle β between the first receiving surface 21 and the preset surface 41 is too large, the first light receiver 20 and the second light receiver 30 need to be set at a position far away from the light source 10 to detect the signal of the detection light, which is not conducive to the miniaturization of the detection device 100. In addition, it will also increase the transmission path of the detection light, reduce the light intensity of the detection light, reduce the signal intensity of the detection light detected by the first light receiver 20 and the second light receiver 30, and reduce the detection sensitivity of the detection device 100.

[0053] In some embodiments, the second light receiver 30 has a second receiving surface 31 , and the angle γ between the second receiving surface 31 and the preset surface 41 is in the range of 40°≤γ≤50°.

[0054] It should be noted that, when the detection device 100 is in use, the second receiving surface 31 faces the workpiece to be processed.

[0055] Optionally, the second receiving surface 31 is used to receive the detection light reflected by the workpiece to be processed.

[0056] It can be understood that the second light receiver 30 receives and senses the detection light through the second receiving surface 31 .

[0057] Specifically, the angle γ between the second receiving surface 31 and the preset surface 41 can be, but is not limited to, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, etc. If the angle γ between the second receiving surface 31 and the preset surface 41 is too small, the distance between the first light receiver 20 and the second light receiver 30 and the light source 10 is too close, which is not conducive to the arrangement of the first light receiver 20, the second light receiver 30 and the light source 10. In addition, if the angle γ between the second receiving surface 31 and the preset surface 41 is too small, the detection device 100 needs to be set at a position far away from the workpiece to be processed in order to detect the workpiece to be processed, and the light intensity of the detection light is easily weakened during the transmission process, which reduces the signal intensity of the detection light detected by the first light receiver 20 and the second light receiver 30, and reduces the detection sensitivity of the detection device 100; if the angle γ between the second receiving surface 31 and the preset surface 41 is too large, the first light receiver 20 and the second light receiver 30 need to be set at a position far away from the light source 10 to detect the signal of the detection light, which is not conducive to the miniaturization of the detection device 100. In addition, it will also increase the transmission path of the detection light, reduce the light intensity of the detection light, reduce the signal intensity of the detection light detected by the first light receiver 20 and the second light receiver 30, and reduce the detection sensitivity of the detection device 100.

[0058] In some embodiments, the detection device 100 can detect a distance d in the range of 3 mm ≤ d ≤ 20 mm.

[0059] Specifically, the detection device 100 can detect a distance d in the range of, but is not limited to, 3mm to 8mm, 3mm to 10mm, 3mm to 15mm, 3mm to 20mm, 5mm to 10mm, 5mm to 15mm, 5mm to 20mm, 10mm to 15mm, 10mm to 20mm, etc.

[0060] It should be noted that when the distance between the workpiece to be processed and the preset surface 41 is less than the minimum distance detectable by the detection device 100, or the distance between the workpiece to be processed and the preset surface 41 is greater than the maximum distance detectable by the detection device 100, the detection device 100 cannot detect the workpiece to be processed, and only the workpiece to be processed whose distance from the preset surface 41 is within the detectable distance range can be detected.

[0061] In this embodiment, when the minimum value of the detectable distance d of the detection device 100 is too small, the positions of the light emitting light source 10 and the first light receiver 20 are too close, which is not conducive to the arrangement of the light emitting light source 10 and the first light receiver 20; when the maximum value of the detectable distance d of the detection device 100 is too large, the positions of the light emitting light source 10 and the second light receiver 30 are too far, which is not conducive to the miniaturization of the detection device 100 and also reduces the signal strength and detection sensitivity of the detection device 100.

[0062] In some embodiments, the minimum distance w1 between the light source 10 and the first light receiver 20 is in the range of 8mm≤w1≤16mm. Specifically, the minimum distance w1 between the light source 10 and the first light receiver 20 may be, but is not limited to, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, etc. If the minimum distance w1 between the light source 10 and the first light receiver 20 is too small, the minimum distance detectable by the detection device 100 is too small, and the detection device 100 is applied to the workpiece too close, which affects the placement of the workpiece; if the minimum distance w1 between the light source 10 and the first light receiver 20 is too large, the distance between the detection device 100 and the workpiece is too large when the detection device 100 is used, which makes the optical path of the detection light too long, thereby reducing the detection sensitivity of the detection device 100.

[0063] In some embodiments, the minimum distance w2 between the light source 10 and the second light receiver 30 is in the range of 16 mm≤w2≤32 mm.

[0064] Specifically, the minimum distance w2 between the light source 10 and the second light receiver 30 may be, but is not limited to, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, etc. If the minimum distance w2 between the light source 10 and the second light receiver 30 is too small, the minimum distance detectable by the detection device 100 is too small, and the detection device 100 is applied to a workpiece too close to the workpiece, which affects the placement of the workpiece; if the minimum distance w2 between the light source 10 and the second light receiver 30 is too large, the detection device 100 is too far away from the workpiece when in use, which makes the optical path of the detection light too long, thereby reducing the detection sensitivity of the detection device 100.

[0065] In some embodiments, the light source 10 has a light emitting surface 11, and the angle α between the light emitting surface 11 and the preset surface 41 is 45°; the first light receiver 20 has a first receiving surface 21, and the angle β between the first receiving surface 21 and the preset surface 41 is 45°; the second light receiver 30 has a second receiving surface 31, and the angle γ between the second receiving surface 31 and the preset surface 41 is 45°.

[0066] In this embodiment, the angle design of the first light receiver 20, the second light receiver 30 and the light source 10 makes the detection device 100 more compact and has a more moderate detection distance range and higher detection sensitivity.

The detection device 100 includes a light source 10, a first light receiver 20 and a second light receiver 30.
