Description

Component detection device

technical field

The utility model relates to a component detection device, in particular to a component detection device capable of obtaining images of the outer peripheral surface of a component to be tested at various angles, so as to detect defects of the component to be tested.

Background technique

Components such as screws, nuts, pins or rivets are used in a wide range of industries, and various industries such as machinery, manufacturing, electronics or construction require a large number of such components. In recent years, due to the rapid progress of science and technology, automated production lines are becoming more and more prosperous. Once the above-mentioned components are defective in the automated production line, any step in the production process cannot be carried out, which will directly cause the entire production line to stop, causing huge losses to the industry. Therefore, the development of automated production and precision technology has led to a significant increase in the industry's quality requirements for the components.

For this reason, manufacturers producing the above-mentioned components are all trying their best to increase the pass rate of products and reduce the probability of product defects. Taking screws as an example, traditional screw manufacturers mainly rely on manpower for product inspection, usually by visually identifying whether the screws are flawed, or by using a ring thread gauge (Ring Thread Gauge) to conduct random inspections on the screws. However, there is a problem of human judgment error in naked eye identification, and its accuracy has long failed to meet the needs of the industry. Although thread ring gauges have better accuracy, they may cause damage to the thread during the inspection process, which is likely to cause unnecessary losses. Moreover, the efficiency of the manual inspection method is not high. For manufacturers with large output, it is usually only possible to carry out random inspection of products in batches, and it is impossible to inspect each screw produced.

In order to solve the above problems, please refer to FIG. 1 , a conventional component inspection device 9 includes a component receiving turntable 91 and an image capture module 92 . The component receiving turntable 91 can hold several components S to be tested, and the image capture module 92 is used to take images of the components S to be tested as a basis for detecting whether the components S to be tested have defects, and then replace Traditional human inspection methods. An embodiment of the conventional component inspection device 9 has been disclosed in the Republic of China Patent Publication No. M323343 "Improvement of an Imaging Device for Component Inspection".

The width, tooth pitch, and inner and outer tooth diameters of the component S are larger than the tolerance, or whether the component S to be tested has problems such as missing corners, cusp expansion, or tooth front width abnormalities. It should be noted that if the image capture module 92 is shooting the location of the defective part S1, since the image captured by the image capture module 92 is a planar image, there is a very high probability that the defect cannot be detected through image recognition. Moreover, if the image capture module 92 is facing away from the location of the flawed portion S1 to shoot, the image capture module 92 will not be able to capture the flawed portion S1 at all. In other words, the image capture module 92 must take pictures from both sides of the position where the defective part S1 is located, in order to effectively detect the defective part S1 by image recognition.

Although the image capture module 92 may include several image capture devices 921, 922 to capture images of the DUT S at different angles, the number of the image capture modules 92 is limited due to space constraints. , it is impossible to capture the images of the peripheral surface of the DUT S at all angles. Accordingly, the conventional component testing device 9 is bound to be unable to completely detect possible flaws that may exist at various angles on the outer peripheral surface of the component S to be tested, so even if the conventional component testing device 9 is used to test the produced components, it is still impossible to ensure that all The detection of defective components is an insurmountable hidden worry for product quality.

In view of this, there is an urgent need to provide a further improved component inspection device, which obtains images of the outer peripheral surface of a component under test at various angles, and detects the defect of the component under test according to the component detection device, so as to improve component defect detection. The accuracy rate ensures that the quality of components produced by manufacturers can meet the increasingly stringent demands of the industry.

Please refer to Figures 4 and 5, when the component testing device of the embodiment of the present invention is actually used, several components S to be tested can be sequentially inserted into the component carrier through a feeding mechanism (not shown). In each positioning slot 121 of the table 1, the DUT S is made of magnetic material (including soft magnetic material and hard magnetic material). The positioning groove 121 can be used to support and position the component under test S, and the positioning groove 121 can be movably combined with the component under test S, so that when the component under test S is positioned in the positioning groove 121, it can move along the axial direction X slides in the positioning groove 121 . At the same time, the driving device 22 of the component driving device 2 drives the magnetic member 24 to rotate through the pivot 23 .

Please also refer to FIG. 6, the power element coupled to the rotating shaft 11 of the component carrier 1 is preferably a stepping motor, so the power element can drive the carrier plate 12 to rotate to a predetermined position, so that one of the positioning The groove 12 is aligned with the magnetic piece 24 along the axial direction X, the magnetic piece 24 is coaxial with the positioning groove 12, and the positioning groove 12 supports a component S to be measured, because the component S to be measured is magnetic material, so the magnetic member 24 can absorb the DUT S by magnetic force. Wherein, the magnetic piece 24 is driven by the driving device 22 to rotate, so the component under test S will be driven by the magnetic piece 24 to rotate after being attracted by the magnetic piece 24 . In order to ensure that the magnetic force of the magnetic piece 24 is sufficient to absorb the component under test S, and at the same time avoid the excessive displacement of the component under test S after being attracted by the magnetic piece 24, the magnetic piece 24 and the component under test S are The distance between the axial directions X is preferably between 0.1 cm and 3 cm, and the distance can be adjusted by the first vertical adjustment part 252 of the first adjustment part 25 .

At this time, the light source 31 of the light source module 3 can project light toward the component under test S in the positioning groove 121 through the light-emitting end 311, and the photographing device 41 of the photographing module 4 can capture the test component S through the lens 411 at the same time. Image of component S. Note that, in this embodiment, the driving device 22 drives the magnetic member 24 to pivot relative to the axial direction X, so the component under test S will pivot with the magnetic member 24 relative to the axial direction X; The light source 31 generates a linear light parallel to the axial direction X, and projects the linear light onto the component under test S through the light-emitting end 311; A linear image parallel to the axial direction X. Accordingly, when the component under test S rotates with the magnetic member 24 , the imaging device 41 can continuously take pictures of the component under test S, and then obtain linear images of the outer peripheral surface of the component under test S at various angles. Specifically, the shooting frequency of the imaging device 41 should correspond to the rotational speed of the component under test S, so as to correctly obtain linear images of the outer peripheral surface of the component under test S at various angles. For example, if the imaging device 41 is The scanning frequency (Line Rate) is approximately equal to the line scan camera of 4.8kHz, and the user wants to obtain 3600 linear images around the outer peripheral surface of the DUT S, then the DUT S should rotate 0.75 circles per second, in other words, the drive The device 22 should drive the magnetic member 24 to rotate at 45 rpm.

After the imaging device 41 captures the linear images of the outer peripheral surface of the component under test S at various angles, the linear images of the outer peripheral surface of the component under test S at various angles can be combined to form a linear image through a computer or a conventional computing device of a workstation. The planar image is used to detect whether there is a defect in the component S under test. In this embodiment, the component under test S is a screw, so the planar image can be used to effectively check whether the width, pitch and internal and external diameter of the component under test S are less than the tolerance, and detect the component under test S Whether there are problems such as missing corners, cusp expansion, or abnormal front width.

In more detail, please refer to FIG. 7 , which is a schematic diagram showing the installation direction of the light emitting end 311 of the light source 31 and the lens 411 of the photographing device 41 . The light-emitting end 311 projects the linear light toward an edge of the device under test S, and the lens 411 is set toward the edge to capture a linear image of the device under test S, and the center of the device under test S faces toward the edge. The edge extends to form a normal direction N. Wherein the connection between the light-emitting end 311 and the edge and the normal direction N forms a first included angle θ ₁ ; the connection between the lens 411 and the edge and the normal direction N forms a second included angle θ _2. When the first angle θ ₁ is equal to the second angle θ ₂ through design, the light projected by the light-emitting end 311 will be directly reflected to the lens 411, so if there is a missing corner in the component under test Such defects will cause uneven brightness or discontinuous lines in the linear image captured by the photographing device 41 , which can effectively detect whether there is a defect in the DUT S. At the same time, for the component S to be tested through electroplating treatment or other bright surface treatment, if the design makes the first included angle θ ₁ equal to the second included angle θ ₂ , the linear image taken by the photographing device 41 will be too large. The defect is too bright to be identified, so the first angle θ ₁ can be designed to be different from the second angle θ ₂ to reduce the light of the linear image captured by the photographing device 41 .

In other words, the installation direction of the light-emitting end 311 of the light source 31 and the lens 411 of the photographing device 41 should be adjusted according to the type of the device under test S and the type of defect to be detected. Accordingly, the second adjustment part of the light source module 3 32 must include the second horizontal adjustment part 321, which is used to adjust the position of the light source 31 on the plane perpendicular to the axial direction X, and then change the installation direction of the light emitting end 311; similarly, the third part of the camera module 4 The adjustment part 42 must include the third horizontal adjustment part 421 for adjusting the position of the photographing device 41 on a plane perpendicular to the axial direction X, thereby changing the installation direction of the lens 411 .

Please refer to FIG. 8 , after the photographing device 41 finishes capturing the linear images of the outer peripheral surface of the component under test S at various angles, the power element coupled to the rotating shaft 11 can drive the carrier plate 12 to rotate again, so that The positioning groove 121 moves on a plane perpendicular to the axial direction X. Since the component under test S is positioned in the positioning groove 121, the component under test S will be forced to disengage from the magnetic member 24 when the carrier plate 12 rotates. , and the power element can drive the carrier plate 12 to continuously rotate to another predetermined position, so that a positioning groove 12 supporting another DUT S is aligned with the magnetic member 24 along the axial direction X. Thereby, by repeating the above-mentioned actions, the photographing device 41 can photograph the DUT S in each of the positioning grooves 12 , so as to detect whether each DUT S has a defect. In addition, the tested components S can be sequentially taken out from the positioning slots 121 through a material taking mechanism (not shown in the figure). A person of ordinary skill in the art can easily understand the well-known techniques, and will not repeat them here.

On the other hand, in this embodiment, the carrier plate 12 is preferably detachably combined with the rotating shaft 11 . In this way, when the user intends to test the DUT S of different specifications, the carrier plate 12 can be replaced correspondingly, so as to provide an appropriate positioning groove 121 to support and position the DUT S of different specifications. For this reason, the component driving device 2 must be provided with the first adjustment part 25, so that after the carrier plate 12 is replaced, the position of the magnetic part 24 can be adjusted to match one of the positioning grooves 121 by means of the first horizontal adjustment part 251. Counterpoint each other. In addition, since the carrier plate 12 corresponding to the DUT S of different specifications may need to be set at different horizontal heights, the second adjustment part 32 of the light source module 3 must include the second vertical adjustment part 322 for adjusting the The position of the light source 31 on the axial direction X ensures that the linear light projected by the light-emitting end 311 can completely illuminate the device under test S; similarly, the third adjustment part 42 of the camera module 4 must include the third The vertical adjustment part 422 is used to adjust the position of the photographing device 41 in the axial direction X to ensure that the captured linear image completely covers the DUT S.

With the above structure, the component detection device of the embodiment of the present invention drives the magnetic part 24 to rotate through the driving device 22 of the component driving device 2, and the magnetic part 24 can be used to attract the component S to be tested, so as to drive the component S to be tested together. The component under test S is rotated, and the light source 31 projects linear light toward the component under test S, and at the same time, the imaging device 41 is used to continuously capture linear images of the component under test S, so that the outer peripheral surface of the component under test S at each The linear image under the angle is used to detect whether there is a defect in the component S under test.

It is worth noting that, please refer to FIG. 9 and FIG. 10 together, if the length of the component under test S' supported in the positioning groove 121 along the axial direction X is longer, when the component under test S' is subjected to When the magnetic part 24 is attracted and driven to rotate, the part of the component under test S′ away from the positioning groove 121 may shake, thus causing the linear image captured by the photographing device 41 to be blurred, which may cause the component under test to be measured. The measuring element S' was misjudged as a defective product. Accordingly, the component detection device of the embodiment of the utility model can also be provided with a support module 5, the support module 5 includes a bracket 51, two support rods 52 and a driving part 53, the two support rods 52 are combined with the bracket 51, And it is disposed toward the DUT S′ in the positioning groove 121 opposite to the magnetic member 24 , and the two supporting rods 52 and the magnetic member 24 are respectively formed on two sides of the carrier plate 12 . Each support rod 52 is provided with a permanent magnet 521 and a guide wheel 522 , the permanent magnet 521 and the guide wheel 522 can be aligned along the axial direction X, and the guide wheel 522 is pivotally coupled to the support rod 52 . The driving part 53 is connected to the support 51 for driving the support 51 and the two support rods 52 to approach or move away from the test element S'.

In this way, please refer to FIG. 11 , when the component under test S is attracted by the magnetic member 24 and driven to rotate, the driving part 53 can drive the two support rods 52 to approach the component under test S′, The component under test S′ is respectively abutted against the two guide wheels 522 to achieve the effect of stably supporting the component under test S′. Since the guide wheel 522 is pivotally connected to the support rod 52, the two support rods 52 will not hinder the rotation of the DUT S′, and the two support rods 52 can attract the DUT through the permanent magnet 521. S', effectively preventing the DUT S' from shaking during rotation.

At the same time, please refer to FIG. 12 , after the photographing device 41 finishes capturing the linear images of the outer peripheral surface of the DUT'S at various angles, the power element coupled to the rotating shaft 11 needs to drive the carrier plate 12 to rotate, A positioning groove 12 supporting another DUT S′ is aligned with the magnetic member 24 along the axial direction X. However, if the DUT S' abuts against the guide wheels 522 of the two support rods 52, the carrier plate 12 cannot rotate smoothly, and even damages the DUT S'. Therefore, the driving part 53 must drive the two support rods 52 away from the component under test S', so that the component under test S' is separated from the guide wheels 522 of the two support rods 52, so that the carrier plate 12 can rotate smoothly.

The driving part 53 can be various conventional power output devices such as a cylinder or a motor. At the same time, the driving part 53 is preferably combined with the power element coupled to the rotating shaft 11 via a transmission structure (not shown in the figure), When the power element drives the rotating shaft 11 to rotate, the transmission structure can be used synchronously to convert the power for driving the rotating shaft 11 to pivot axially into the power for driving the bracket 51 to generate radial displacement, thereby enabling the two support rods The action of 52 is synchronized with the rotation process of the carrier plate 12, further ensuring that the carrier plate 12 can rotate smoothly to switch the positioning groove 121 that is aligned with the magnetic member 24.

With the structural features disclosed above, the main features of the component detection device in the embodiment of the present invention are:

A component carrier 1 is used to provide several positioning grooves 121, and each positioning groove 121 can be movably combined with a component S to be tested; a magnetic member 24 is driven to rotate by a driving device 22 of a component driving device 2, and the component carrier 1 The positioning slots 12 supporting the element S to be tested can be driven to move on a plane perpendicular to the axial direction X, so as to align with the magnetic piece 24 along the axial direction X, so as to use the magnetic piece 24 to attract The component under test S also drives the component under test S to rotate; cooperate with a light source 31 to project linear light towards the component under test S, and at the same time use a photographic device 41 to continuously capture linear images of the component under test S, and then obtain Linear images of the peripheral surface of the DUT S under various angles.

It can be seen that, compared with the aforementioned conventional component testing device 9, which can only use several image capture devices 921, 922 to capture images of the component under test S at different angles, the component testing device of the embodiment of the present invention can obtain the The images of the outer peripheral surface of the component S under test at various angles are used to detect whether the component S under test has defects, so it is possible to completely detect the possible defects of the outer peripheral surface of the component S under test at various angles, and has the ability to improve component defects. The power of detection accuracy.

Furthermore, if the length of the component under test S' supported in the positioning groove 121 is relatively long, the component detection device according to the embodiment of the present invention can stably support the component under test S' by means of a support module 5, the support module 5 Contains two support rods 52, and the two support rods 52 and the magnetic piece 24 are respectively formed on both sides of the component carrier 1, the two support rods 52 can abut the DUT S', avoiding the DUT S Shaking is generated during the rotation driven by the magnetic part 24, so as to ensure the quality of the linear image captured by the photographic device 41, reduce the probability that the component under test S' is misjudged as a defective product, and further improve component defect detection The effect of accuracy.

To sum up, the component detection device of the present invention can indeed achieve the effect of improving the detection accuracy of component defects.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and deformations can also be made. And deformation should also be regarded as the protection scope of the present utility model.
