Description

Technical Field

[0001] The present application relates to the technical field of circuit board detection, and in particular to a circuit board detection device. Background Art

[0002] In recent years, the continuous development of information technology has led to the rapid development of circuit boards as an important part of information technology. In order to ensure that the output circuit boards are qualified products, circuit boards need to be inspected for defects during the production process. At the same time, with the increasing advancement of artificial intelligence, the use of visual algorithms to inspect circuit boards is gradually replacing traditional manual inspections.

[0003] The inventors of this application have discovered that although visual algorithms have developed rapidly in circuit board quality inspection, the corresponding hardware is difficult to meet several requirements such as easy replacement, maintenance-free, and low cost. Summary of the invention

[0004] The main technical problem solved by the present application is to provide a circuit board detection device that can save production costs.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: to provide a circuit board detection device, comprising: a detection bracket, which is used to be detachably installed on the transportation path of the circuit board, and an imaging location is provided in the space area surrounded by the detection bracket; a light source installation assembly, which is connected to the detection bracket and erected on the transportation path, and the light source installation assembly is used for detachably installing the light source, wherein the light source installation assembly is provided with a plurality of first installation parts, and different light sources are connected to the light source installation assembly through matching first installation parts.

[0006] The beneficial effect of the present application is that in the circuit board detection device of the present application, a light source mounting assembly for mounting a light source is provided with a plurality of first mounting parts. When different light sources need to be used due to different circuit board formats, different light sources can select matching first mounting parts to be mounted on the light source mounting assembly. In other words, the light source mounting assembly can install different light sources, so that the circuit board detection device can meet the detection requirements of circuit boards of various formats, realize "one machine for multiple uses", and thus reduce production costs.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] See also Figures 1 to 3 The circuit board detection device 1000 includes a detection bracket 1100, an imaging installation component 1200 and a controller (not shown).

[0032] The detection bracket 1100 is detachably mounted on the transportation path 1300 of the circuit board, wherein an imaging location 1101 is provided in the space area surrounded by the detection bracket 1100 .

[0033] In this embodiment, if Figure 2As shown, two parallel tracks 1310 are used to transport the circuit board A, and the detection bracket 1100 is detachably installed on the two tracks 1310. At this time, the transportation path 1300 is formed between the two parallel tracks 1310, and the extension direction of the transportation path 1300 is consistent with the extension direction of the two tracks 1310. At this time, the detection bracket 1100 is set on the two tracks 1310 to construct a spatial area on one side of the transportation path 1300.

[0034] Specifically, when the circuit board A on the transport path 1300 needs to be inspected, the inspection bracket 1100 is installed on the two rails 1310 , and when the circuit board A does not need to be inspected, the inspection bracket 1100 can be removed.

[0035] Of course, in other embodiments, the two tracks 1310 for transporting circuit board A may be arranged non-parallel, or other methods may be used to transport circuit board A, such as using a conveyor belt. In this case, the detection bracket 1100 may be arranged adjacent to the conveyor belt. In short, this application does not impose any restrictions on how the detection bracket 1100 is arranged on the transport path 1300.

[0036] Meanwhile, the imaging location 1101 may be a specific location point or a location range, which is located in the space area surrounded by the detection bracket 1100 .

[0037] The number of imaging mounting components 1200 is at least two, for example, two, five or more (the figures illustrate the number of imaging mounting components 1200 as two), and each imaging mounting component 1200 is used to install a different number of imaging devices, wherein the imaging device can be an ordinary camera, a CCD camera or other device with imaging function.

[0038] At least two imaging installation components 1200 are arranged on the detection bracket 1100 in an adjustable position, and each imaging installation component 1200 can be adjusted to the imaging position 1101 .

[0039] At the same time, the controller controls the imaging device installed on the imaging installation component 1200 located at the imaging position 1101 to image the circuit board. That is, when it is necessary to use the imaging device on a certain imaging installation component 1200 to image the circuit board, the imaging installation component 1200 needs to be adjusted to the imaging position 1101, wherein, when the imaging device is located at the imaging position 1101, its imaging field of view will not be blocked in any way, and the quality of the final imaging can be guaranteed.

[0040] Specifically, different types of circuit boards A have different imaging requirements. For example, some circuit boards A only include one circuit board unit, while some circuit boards A include multiple circuit board units, or two circuit boards A that also include only one circuit board unit have different sizes. At this time, one imaging device is difficult to meet multiple imaging requirements at the same time due to the limited imaging field of view. Therefore, different numbers of imaging devices need to be set for circuit boards A of different types. In this embodiment, since at least two imaging installation components 1200 used to install different numbers of imaging devices can be adjusted to the imaging position 1101, when a certain type of circuit board A is detected, the imaging installation component 1200 that can install a corresponding number of imaging devices can be adjusted to the imaging position 1101, and a corresponding number of imaging devices can be installed on the imaging installation component 1200. That is to say, the circuit board detection device 1000 in this embodiment can meet the detection requirements of circuit boards A of multiple types at the same time. Compared with the prior art in which one machine can only detect one type of circuit board A, this embodiment can greatly reduce costs.

[0041] See also Figure 3 and Figure 4 The circuit board detection device 1000 also includes a connection component 1400 .

[0042] The connection component 1400 is adjustably disposed on the detection bracket 1100, wherein at least two imaging installation components 1200 are respectively connected to the connection component 1400, and at least two imaging installation components 1200 can be respectively adjusted to the imaging position 1101 as the position of the connection component 1400 relative to the detection bracket 1100 is adjusted.

[0043] Specifically, through the above-mentioned arrangement, the positions of multiple imaging mounting components 1200 can be adjusted simultaneously by adjusting the position of the connecting component 1400. When it is necessary to adjust a certain imaging mounting component 1200 to the imaging position 1101, the position of the connecting component 1400 relative to the detection bracket 1100 is adjusted accordingly, thereby eliminating the need to adjust the positions of at least two imaging mounting components 1200 separately. In other words, when it is necessary to adjust a certain imaging mounting component 1200 to the imaging position 1101, the position of the connecting component 1400 can be directly adjusted, which is convenient and quick.

[0044] In one application scenario, the connecting component 1400 is rotatably connected to the detection bracket 1100 to achieve an adjustable position on the detection bracket 1100. At this time, when it is necessary to adjust a certain imaging installation component 1200 to the imaging position 1101, it is only necessary to rotate the connecting component 1400 to a suitable angle relative to the detection bracket 1100.

[0045] In another application scenario, the connecting component 1400 is slidably connected to the detection bracket 1100 to achieve an adjustable position on the detection bracket 1100. At this time, when it is necessary to adjust a certain imaging mounting component 1200 to the imaging position 1101, it is only necessary to slide the connecting component 1400 relative to the detection bracket 1100 to a suitable position.

[0046] In summary, the present application does not limit how the connection assembly 1400 is adjusted in position on the detection bracket 1100 .

[0047] Continue reading Figure 3 The detection bracket 1100 includes four support members 1110 and two first connecting members 1120. The four support members 1110 are symmetrically erected in groups of two on two rails 1310 for transporting circuit boards A. The two first connecting members 1120 are respectively connected to the two support members 1110 erected on the same rail 1310.

[0048] Specifically, the arrangement of four support members 1110 and two first connecting members 1120 can ensure the stability of the detection bracket 1100. Among them, the support members 1110 and the first connecting members 1120 are both straight plate structures. In other embodiments, the support members 1110 and the first connecting members 1120 can also be round rods or other structures, which are not limited here.

[0049] In other embodiments, the number of the supporting members 1110 may be more than four, and the number of the first connecting members 1120 may be more than two, which is not limited here.

[0050] In one application scenario, in order to be able to adjust the distance between two support members 1110 arranged on the same track 1310, the first connecting member 1120 is provided with a plurality of connecting portions 1121 arranged at intervals along its extension direction, and the two support members 1110 are fixed to the first connecting member 1120 in an adjustable position through the plurality of connecting portions 1121, wherein the connecting portion 1121 may be a through hole. When it is necessary to adjust the distance between the two support members 1110 on the same track 1310, fasteners such as screws are used to pass through the corresponding through holes to lock the support members 1110 and the first connecting member 1120.

[0051] Continue reading Figure 3 and Figure 4 The connecting component 1400 includes two second connecting members 1410, and the two second connecting members 1410 are rotatably connected to the two first connecting members 1120 respectively, so that the connecting component 1400 can be rotatably connected to the detection bracket 1100, wherein at least two imaging mounting components 1200 are simultaneously connected to the two second connecting members 1410.

[0052] Specifically, each imaging mounting assembly 1200 is connected to two second connecting members 1410 , wherein the two second connecting members 1410 can ensure the installation fixity of the imaging mounting assembly 1200 and the stability of the position adjustment process compared to one second connecting member 1410 .

[0053] At the same time, the rotation axes of the two second connecting members 1410 relative to the first connecting member 1120 are located on the same horizontal line, and the number of the at least two imaging mounting assemblies 1200 is two, and the two imaging mounting assemblies 1200 are respectively connected to the proximal ends of the two second connecting members 1410. For the convenience of description, the two imaging mounting assemblies 1200 are respectively defined as the first imaging mounting assembly 1210 and the second imaging mounting assembly 1220. In an application scenario, the first imaging mounting assembly 1210 can be installed with one imaging device, and the second imaging mounting assembly 1220 can be installed with two imaging devices.

[0054] At this time, when it is necessary to switch the imaging installation component 1200 located at the imaging location 1101, the two second connecting parts 1410 are rotated relative to the detection bracket 1100, so that the first imaging installation component 1210 originally located at the imaging location 1101 can be switched to the second imaging installation component 1220, or the second imaging installation component 1220 originally located at the imaging location 1101 can be switched to the first imaging installation component 1210.

[0055] In this embodiment, if Figure 3 As shown, the second connecting member 1410 is in a straight plate structure. At this time, the two second connecting members 1410 rotate 180 degrees relative to the detection bracket 1100 to complete the switching of the imaging installation component 1200 located at the imaging position 1101. At this time, the controller controls the imaging device located on the imaging installation component 1200 installed below to image the circuit board. That is to say, at this time, the imaging position 1101 is Figure 3 The position range of the second imaging mounting assembly 1220.

[0056] In other embodiments, the connecting component 1400 may include only one second connecting member 1410, in which case the one second connecting member 1410 may be rotatably connected to two first connecting members 1120 at the same time, or may be rotatably connected to only one first connecting member 1120, and at the same time, the first imaging mounting component 1210 and the second imaging mounting component 1220 are respectively connected to the two ends of the second connecting member 1410.

[0057] See also Figure 4 and Figure 5 The first imaging installation assembly 1210 and the second imaging installation assembly 1220 both include an imaging installation back plate 1211 , a first imaging installation slide rail 1212 and a first imaging installation slider 1213 .

[0058] The imaging mounting back plate 1211 includes a first back plate surface 12111 and a second back plate surface 12112 which are arranged opposite to each other. One end of the imaging mounting back plate 1211 is fixedly connected to a second connecting member 1410 for mounting an imaging device. A first imaging mounting slide rail 1212 is arranged on the first back plate surface 12111 of the imaging mounting back plate 1211. A first imaging mounting slider 1213 is slidably arranged on the first imaging mounting slide rail 1212 and is fixedly connected to another second connecting member 1410. When the distance between the two second connecting members 1410 is adjusted, the first imaging mounting slider 1213 slides along the first imaging mounting slide rail 1212.

[0059] Specifically, for circuit boards A of different formats, their sizes are different, and the spacing between the two tracks 1310 used for transportation is also different. It can be understood that when the spacing between the two tracks 1310 is different, the spacing between the two second connectors 1410 is required to change. Therefore, in order to enable the circuit board A detection device 1000 to meet the detection requirements of circuit boards A of different formats, an imaging installation back plate 1211, a first imaging installation slide rail 1212 and a first imaging installation slider 1213 are provided, so that the imaging device can be installed and the spacing between the two second connectors 1410 can be adjusted.

[0060] Continue reading Figure 4 and Figure 5 The first imaging mounting assembly 1210 and the second imaging mounting assembly 1220 further include a second imaging mounting rail 1214 and a second imaging mounting slider 1215 .

[0061] The second imaging mounting rail 1214 is arranged on the second back plate surface 12112 of the imaging mounting back plate 1211 ; the second imaging mounting slider 1215 is slidably arranged on the second imaging mounting rail 1214 for mounting the imaging device and making the imaging device slide along the second imaging mounting rail 1214 .

[0062] Specifically, when the position of the imaging device on the imaging mounting back plate 1211 needs to be adjusted, the second imaging mounting slider 1215 slides relative to the second imaging mounting rail 1214, thereby driving the imaging device to slide and changing the imaging field of view of the imaging device.

[0063] In one application scenario, the second imaging mounting slide rail 1214 is an electrically controlled slide rail, which can control the sliding distance of the second imaging mounting slider 1215 .

[0064] Among them, each second imaging mounting slide rail 1214 is equipped with a second imaging mounting slider 1215, and each second imaging mounting slider 1215 is equipped with an imaging device. Therefore, in an application scenario, Figure 5As shown, the first imaging mounting assembly 1210 includes one second imaging mounting rail 1214 , and the second imaging mounting assembly 1220 includes two second imaging mounting rails 1214 .

[0065] In other implementations, the second imaging installation rail 1214 and the second imaging installation slider 1215 may not be provided, and the imaging device may be directly installed on the imaging installation back plate 1211 .

[0066] See also Figure 3 The two second connecting members 1410 are detachably connected to the two first connecting members 1120 respectively.

[0067] Specifically, when it is necessary to switch the imaging installation component 1200 located at the imaging location 1101, the two second connecting components 1410 are separated from the two first connecting components 1120 respectively, and then the two second connecting components 1410 are flipped 180 degrees. At this time, the positions of the first imaging installation component 1210 and the second imaging installation component 1220 are swapped, thereby realizing the switching of the imaging installation component 1200 located at the imaging location 1101.

[0068] In other embodiments, the connection between the two second connecting members 1410 and the two first connecting members 1120 may also be a non-detachable connection. For example, the two second connecting members 1410 are rotatably connected to the two first connecting members 1120 via a rotating shaft, respectively, and the rotating shaft makes the second connecting members 1410 and the first connecting members 1120 inseparable, but during the adjustment process, the rotating shaft can be loosened to allow the second connecting member 1410 to rotate around the rotating shaft relative to the first connecting member 1120, and the rotating shaft can be locked to fix the second connecting member 1410 relative to the first connecting member 1120, so when it is necessary to switch the imaging mounting assembly 1200 located at the imaging location 1101, the rotating shaft can be loosened first and then locked.

[0069] In summary, this application does not limit whether the second connecting member 1410 can be separated from the first connecting member 1120 .

[0070] Combination Figure 3 and Figure 4 The circuit board detection device 1000 also includes a bending piece 1500 .

[0071] There are two bending pieces 1500, so that the two second connecting pieces 1410 are respectively detachably connected to the two first connecting pieces 1120. The bending piece 1500 specifically includes a first connecting plate 1510 and a second connecting plate 1520 connected at a certain angle (for example, 90 degrees). The first connecting plate 1510 is connected to the second connecting piece 1410, and the second connecting plate 1520 is connected to the first connecting piece 1120. The bending piece 1500 is detachably connected to at least one of the second connecting piece 1410 and the first connecting piece 1120.

[0072] In one application scenario, when rotating the second connecting member 1410, the bending member 1500 is separated from the first connecting member 1120, and then the second connecting member 1410 is flipped over, and then the bending member 1500 is reconnected to the first connecting member 1120. The entire rotation process is convenient and quick.

[0073] In other application scenarios, when the second connecting member 1410 is rotated, the bending member 1500 is separated from the second connecting member 1410, and then the second connecting member 1410 is flipped over, and then the bending member 1500 and the second connecting member 1410 are reconnected.

[0074] In one application scenario, a plurality of through holes are provided on the first connecting plate 1510 and the second connecting plate 1520 , and the bending member 1500 is respectively connected to the second connecting member 1410 and the first connecting member 1120 by means of screw locking.

[0075] In this embodiment, the length of the second connecting member 1410 is adjustable.

[0076] Specifically, when the imaging installation assembly 1200 located at the imaging location 1101 is switched, the field of view of the imaging device may need to be readjusted because the number of imaging devices installed at the imaging location 1101 changes. By making the length of the second connecting member 1410 adjustable, the height of the imaging device located at the imaging location 1101 relative to the circuit board A can be adjusted according to different application scenarios, thereby adjusting the field of view of the imaging device.

[0077] See also Figure 4 and Figure 5 The second connecting member 1410 includes a first sub-connecting member 1411 and a second sub-connecting member 1412. One end of the first sub-connecting member 1411 is connected to the first imaging mounting assembly 1210, one end of the second sub-connecting member 1412 is connected to the second imaging mounting assembly 1220, and the other end of the first sub-connecting member 1411 is fixed to the second sub-connecting member 1412 in an adjustable position.

[0078] The other end of the first sub-connector 1411 is fixed to the second sub-connector 1412 in an adjustable position so as to achieve adjustable length of the second connector 1410 .

[0079] In an application scenario, such as Figure 4 As shown, the first sub-connector 1411 and the second sub-connector 1412 are both provided with a plurality of first through holes 14111 arranged at intervals along their respective extension directions, so that the other end of the first sub-connector 1411 can be fixed to the second sub-connector 1412 in an adjustable position.

[0080] Specifically, when the field of view of the imaging device needs to be adjusted, a fastener such as a screw is used to pass through the corresponding first through hole 14111 to lock the first sub-connector 1411 and the second sub-connector 1412 together.

[0081] In other embodiments, other structures can be used to enable the other end of the first sub-connector 1411 to be fixed to the second sub-connector 1412 in an adjustable position. For example, a boss is provided on the first sub-connector 1411, and a plurality of through holes are provided on the second sub-connector 1412 and are arranged at intervals along its extension direction. In this case, the boss can pass through different through holes to enable the other end of the first sub-connector 1411 to be fixed to the second sub-connector 1412 in an adjustable position. Alternatively, the first sub-connector 1411 is slidably set on the second sub-connector 1412 through a slide rail. In this case, the first sub-connector 1411 can also be fixed to the second sub-connector 1412 in an adjustable position. In short, the present application does not limit the connection method between the first sub-connector 1411 and the second sub-connector 1412.

[0082] See also Figure 6 and Figure 7 The circuit board detection device 1000 also includes a light source mounting assembly 1600 .

[0083] The light source mounting assembly 1600 is connected to the detection bracket 1100 and is used to mount the first light source 1700 .

[0084] The light source installation assembly 1600 is located on the two rails 1310 and its extension direction is perpendicular to the extension direction of the two rails 1310 , so that the first light source 1700 installed on the light source installation assembly 1600 is located between the imaging location 1101 and the transportation path 1300 .

[0085] Specifically, when imaging circuit board A, ambient light plays a decisive role in the quality of imaging. When the ambient light is insufficient, the imaging will be blurred, making it difficult to detect defects on circuit board A. Therefore, when the light is dim, it is necessary to install a first light source 1700 for providing lighting for the circuit board detection device 1000.

[0086] In one application scenario, in order to improve the uniformity of illumination and reduce light reflection, the first light source 1700 is a coaxial light source.

[0087] At the same time, considering that the coaxial light source is generally a rectangular structure, the extension direction of the light source mounting assembly 1600 is set to be perpendicular to the extension direction of the two tracks 1310. This can ensure that the coaxial light source installed on the light source mounting assembly 1600 can be set directly opposite the transmission path 1300, thereby ensuring that the light emitted by the coaxial light source can all be irradiated on the circuit board A.

[0088] Continue reading Figure 6 and Figure 7 The light source installation assembly 1600 is provided with a plurality of first installation parts 1601 , and different types of first light sources 1700 are connected to the light source assembly 1600 through matching first installation parts 1601 .

[0089] For circuit boards A of different types, their sizes are different, and the types of first light sources 1700 required are also different. Therefore, the light source mounting assembly 1600 is provided with a plurality of first mounting portions 1601 for detachably mounting different types of first light sources 1700, so that the circuit board detection device 1000 can meet the detection requirements of circuit boards A of various types, thereby saving costs.

[0090] Continue reading Figure 6 The light source mounting assembly 1600 includes a first light source mounting plate 1610, and the first light source mounting plate 1610 is provided with a plurality of first mounting portions 1601, wherein the first light source mounting plate 1610 is vertically arranged and connected to two supporting members 1110 in the detection bracket 1100, and an extension direction of the first light source mounting plate 1610 is perpendicular to an extension direction of the track 1310.

[0091] Compared with using a mounting rod to mount the first light source 1700 , using the first light source mounting plate 1610 to mount the first light source 1700 can ensure the mounting stability of the first light source 1700 .

[0092] In an application scenario, such as Figure 6 As shown, the plurality of first mounting portions 1601 include a plurality of through holes disposed on the first light source mounting plate 1610, and the apertures and the spacings between the plurality of through holes are set according to the type of the first light source 1700 to be installed, and may be completely the same or not completely the same. At this time, when installing the first light source 1700, the first light source 1700 may be locked on the first light source mounting plate 1610 by using fasteners such as screws to pass through a plurality of through holes matching the first light source 1700 according to the size of the first light source 1700.

[0093] It is understandable that different first light sources 1700 can be connected to the first light source mounting plate 1610 through the same number of through holes, or can be connected to the first light source mounting plate 1610 through different number of through holes, and the specific situation is determined by the mounting part on the first light source 1700.

[0094] In another application scenario, the multiple first mounting portions 1601 include card slots (not shown) arranged on the first light source mounting plate 1610. Similar to the multiple through holes, the sizes of the multiple card slots and the spacing between them may be exactly the same or may not be exactly the same. In this case, when installing the first light source 1700, the first light source 1700 can be clamped in several matching card slots according to the size of the first light source 1700.

[0095] In other application scenarios, multiple first mounting parts 1601 may include multiple through holes and multiple slots at the same time, or, multiple first mounting parts 1601 may also be other structures that can play a fixing role. In short, the present application does not limit the structure of the first mounting part 1601, as long as it can enable different types of first light sources 1700 to be installed on the first light source mounting plate 1610.

[0096] Combination Figure 6 and Figure 8 The mounting assembly 1600 also includes a second light source mounting plate 1620 and a third light source mounting plate 1630 .

[0097] The second light source mounting plate 1620 is arranged parallel to the first light source mounting plate 1610 and connected to the other two supporting members 1110 that are not connected to the first light source mounting plate 1610, and is used to cooperate with the first light source mounting plate 1610 to install the first light source 1700. At the same time, the third light source mounting plate 1630 is perpendicular to the second light source mounting plate 1620 and connected to the side of the second light source mounting plate 1620 close to the transport path 1300, and is used to support the first light source 1700.

[0098] Specifically, the arrangement of the second light source mounting plate 1620 and the third light source mounting plate 1630 can ensure the installation stability of the first light source 1700. In order to ensure that the second light source mounting plate 1620 and the third light source mounting plate 1630 can better cooperate with the first light source mounting plate 1610 to install the first light source 1700, a plurality of first mounting portions 1601 are also provided on the second light source mounting plate 1620 and the third light source mounting plate 1630. When installing different first light sources 1700, the first light source 1700 is installed using the first mounting portion 1601 that matches the first light source 1700. The first mounting portion 1601 arranged on the second light source mounting plate 1620 and the third light source mounting plate 1630 can also be various structures such as through holes and grooves, which are not limited here.

[0099] In this embodiment, in the extension direction of the support member 1110, the first light source mounting plate 1610 and / or the second light source mounting plate 1620 can be connected to the support member 1110 in an adjustable position to adjust the height of the first light source mounting plate 1610 and / or the second light source mounting plate 1620 installed on the support member 1110.

[0100] Specifically, by arranging the first light source mounting plate 1610 and / or the second light source mounting plate 1620 to be connected to the support member 1110 in an adjustable position, the height of the first light source 1700 relative to the circuit board A can be indirectly adjusted.

[0101] See also Figure 6 The support member 1110 is provided with a plurality of second mounting portions 1111 arranged at intervals along its extension direction, and the first light source mounting plate 1610 and / or the second light source mounting plate 1620 are connected to the support member 1110 in an adjustable position through the plurality of second mounting portions 1111.

[0102] Specifically, the setting of the second mounting portion 1111 enables the first light source mounting plate 1610 and / or the second light source mounting plate 1620 to move along the extension direction of the support member 1110. When it is necessary to adjust the height of the first light source 1700 relative to the circuit board A, the first light source mounting plate 1610 and / or the second light source mounting plate 1620 are connected to the support member 1110 through a suitable second mounting portion 1111.

[0103] In one application scenario, multiple second mounting portions 1111 include through holes arranged on the support member 1110. In other application scenarios, multiple second mounting portions 1111 include grooves arranged on the support member 1110. Similar to the first mounting portion 1601, the present application does not limit the structure of the second mounting portion 1111.

[0104] In this embodiment, in the extension direction of the light source mounting assembly 1600 , the distance between the ends of the first light source mounting plate 1610 and / or the second light source mounting plate 1620 relative to the corresponding matching support members 1110 can be adjusted to accommodate the distance adjustment between the two rails 1310 .

[0105] When inspecting circuit boards A of different types, the spacing between the two tracks 1310 may need to be adjusted accordingly. Therefore, the distance between the ends of the first light source mounting plate 1610 and / or the second light source mounting plate 1620 relative to the corresponding matching support members 1110 is adjustable to meet the inspection requirements of different circuit boards A.

[0106] See also Figure 6In this embodiment, a light source installation slide rail 1602 is provided on the surface of the first light source installation plate 1610 and / or the second light source installation plate 1620, and a light source installation slider 1603 is slidably provided on the light source installation slide rail 1602. At the same time, one of the two supporting members 1110 connected to the first light source installation plate 1610 / the second light source installation plate 1620 is fixedly connected to the first light source installation plate 1610 / the second light source installation plate 1620, and the other is fixedly connected to the light source installation slider 1603 on the first light source installation plate 1610 / the second light source installation plate 1620. When the distance between the two supporting members 1110 connected to the first light source installation plate 1610 / the second light source installation plate 1620 is adjusted, the corresponding light source installation slider 1603 slides relative to the light source installation slide rail 1602.

[0107] Specifically, when the distance between the two rails 1310 needs to be adjusted, the light source mounting slider 1603 is slid relative to the light source mounting slide rail 1602, so that the light source mounting slider 1603 drives the support member 1110 connected thereto away from the corresponding other support member 1110, thereby making the two support members 1110 connected to the first light source mounting plate 1610 and the second light source mounting plate 1620 adapt to the distance adjustment between the two rails 1310.

[0108] Combination Figure 6 and Figure 8 The surface area of ​​the first light source mounting plate 1610 is greater than the surface area of ​​the second light source mounting plate 1620. A first number of light source mounting rails 1602 are disposed on the surface of the first light source mounting plate 1610. A second number of light source mounting rails 1602 are disposed on the surface of the second light source mounting plate 1620. The first number is greater than or equal to the second number.

[0109] Specifically, setting the surface area of ​​the first light source mounting plate 1610 to be greater than the surface area of ​​the second light source mounting plate 1620 can save costs. When installing the first light source 1700, the first light source mounting plate 1610 is used as the main mounting plate, and the second light source mounting plate 1620 is used as the auxiliary mounting plate, that is, the first light source mounting plate 1610 plays a major role in mounting and fixing, and the second light source mounting plate 1620 plays a secondary role in mounting and fixing. At the same time, setting the number of light source mounting rails 1602 corresponding to the first light source mounting plate 1610 to be greater than or equal to the number of light source mounting rails 1602 corresponding to the second light source mounting plate 1620 can ensure the stability of the first light source mounting plate 1610 and the second light source mounting plate 1620 when adjusting the spacing between the support members 1110.

[0110] In one application scenario, the first quantity is two and the second quantity is one.

[0111] like Figure 7 and Fig.10As shown, in different application scenarios, only the first light source mounting plate 1610 may be used to mount the first light source 1700 , or the first light source mounting plate 1610 , the second light source mounting plate 1620 and the third light source mounting plate 1630 may be used simultaneously to mount the first light source 1700 .

[0112] Combination Figure 6 and Fig. 9 The circuit detection device 1000 further includes a connecting block 1800 for connecting the track 1310 and the supporting member 1110 respectively.

[0113] The number of the connecting blocks 1800 corresponds to the number of the supporting members 1110 , and the connecting blocks 1800 are provided with a plurality of third mounting portions 1810 arranged at intervals along the extension direction of the track 1310 , and the supporting members 1110 are connected to the connecting blocks 1800 in an adjustable position through the third mounting portions 1810 .

[0114] Specifically, the setting of the third mounting portion 1810 can adjust the distance between two supporting members 1110 arranged on the same track 1310 to meet the detection requirements in different application scenarios.

[0115] In one application scenario, multiple third mounting parts 1810 include mounting holes set on the connecting block 1800. In another application scenario, multiple third mounting parts 1810 include grooves set on the connecting block 1800. Similar to the first mounting part 1601 and the second mounting part 1111, the present application does not limit the structure of the third mounting part 1810.

[0116] Combination Figure 1 , Fig.11 as well as Fig.12 The circuit board detection device 1000 also includes a positioning component 1900, which is used to position the circuit board A, so as to facilitate the subsequent installation of the imaging device according to the position of the circuit board A.

[0117] Among them, the imaging device installed according to the circuit board A positioned by the positioning component 1900 has a different function from the imaging device installed on the imaging mounting component 1200. In order to distinguish them, the imaging device installed on the imaging mounting component 1200 is defined as a first imaging device, and the imaging device installed according to the circuit board A positioned by the positioning component 1900 is defined as a second imaging device.

[0118] Specifically, the first imaging device is used to image the first side of circuit board A to determine whether circuit board A has defects, and the second imaging device is used to image the second side of circuit board A, wherein the second side of circuit board A is provided with a marking point. During detection, when there is a marking point in the image obtained by the second imaging device, the trigger controller controls the first imaging device located at the imaging position 1101 to image the first side of circuit board A. In short, the second imaging device is used to detect the position of circuit board A, specifically to detect whether circuit board A has been transported to the appropriate position.

[0119] Since the second imaging device is used to detect the position of the circuit board A, the installation position of the second imaging device is extremely important. Otherwise, when the installation position of the second imaging device deviates, the circuit board A has reached the appropriate position, but there is no mark point in the image obtained by the second imaging device. Therefore, in this embodiment, the position of the circuit board A is located by the positioning component 1900, and then the second imaging device is installed according to the positioning of the circuit board A to ensure that the installation position of the second imaging device is correct. Specifically, the positioning component 1900 includes a positioning member 1910 and a positioning plate 1920.

[0120] The positioning member 1910 is used to detachably rest against the reference element and extend in a direction away from the reference element; the positioning plate 1920 rests against one end of the positioning member 1910 away from the reference element, and a plurality of positioning portions 1921 are provided on the surface of the positioning plate 1920, wherein when positioning the target element, the surface of the positioning plate 1920 having the plurality of positioning portions 1921 faces the target element to determine the positioning portion 1921 corresponding to the target element.

[0121] In this embodiment, the positioning member 1910 can be detachably abutted against the detection bracket 1100 serving as a reference element, that is, when the circuit board A needs to be positioned, one end of the positioning member 1910 can be brought into contact with the detection bracket 1100 serving as a reference element, and when the circuit board A does not need to be positioned, the positioning member 1910 can be separated from the detection bracket 1100 serving as a reference element.

[0122] At the same time, the positioning plate 1920 abuts against the end of the positioning member 1910 away from the reference element, that is, when the positioning assembly 1900 is used for positioning, the positioning plate 1920 contacts the end of the positioning member 1910 away from the reference element.

[0123] In an application scenario, such as Fig.11 As shown, the positioning member 1910 is detachably abutted against the docking block 1800 as a specific reference element.

[0124] In other embodiments, the positioning member 1910 may also be detachably abutted against the rail 1310 serving as a reference element.

[0125] Meanwhile, in the present embodiment, the circuit board A as the target element is positioned by the positioning assembly 1900 , and then the second imaging device is installed according to the positioning of the circuit board A.

[0126] Specifically, when it is necessary to use the positioning assembly 1900 to locate the position of the circuit board A, the positioning member 1910 is abutted against the docking block 1800, and the positioning plate 1920 is connected to the end of the positioning member 1910 away from the docking block 1800. At this time, the surface of the positioning portion 1921 provided on the positioning plate 1920 faces the circuit board A on the transportation path 1300. At this time, the circuit board A, especially the marking point on the circuit board A, will have an orthographic projection on the positioning plate 1920. Observe the positioning portion 1921 among the multiple positioning portions 1921 that coincides with the projection, and then place the second imaging device at the positioning portion 1921 that coincides with the projection, and finally ensure the installation position of the second imaging device.

[0127] See also Fig.12 , the plurality of positioning portions 1921 include a plurality of positioning holes disposed on the positioning plate 1920 .

[0128] By setting the positioning portion 1921 as a positioning hole, the positioning assembly 1900 can not only play a positioning role, but also a mounting role. Specifically, after the positioning assembly 1900 finds the correct position of the second imaging device, the second imaging device is placed at the corresponding position of the positioning plate 1920, and then the second imaging device is locked on the positioning plate 1920 through the positioning hole.

[0129] In one application scenario, the positioning hole is a through hole. When the second imaging device is subsequently installed, fasteners such as screws can be used to pass through the corresponding through holes to lock the second imaging device on the positioning plate 1920.

[0130] In other application scenarios, the multiple positioning parts 1921 include multiple positioning marks arranged on the positioning plate 1920. At this time, the positioning component 1900 only plays a positioning role and is a tool. Specifically, after the installation position of the second imaging device is found through the positioning component 1900, the second imaging device is placed in the correct position, and then the second imaging device is connected to other components, and finally the positioning component 1900 is taken away.

[0131] It is understandable that when the second imaging device needs to be installed through the positioning assembly 1900, the positioning member 1910 needs to be installed together with the reference element (such as the docking block 1800). At this time, the positioning member 1910 and the reference element can be installed together using fasteners such as screws.

[0132] Among them, the positioning member 1910 and the positioning plate 1920 are detachably connected. Specifically, the positioning member 1910 and the positioning plate 1920 are two independent components. After the positioning plate 1910 and the positioning member 1920 are pressed against each other, the two can be connected by fastening clips such as screws. On the one hand, such a setting is convenient for transportation. On the other hand, when one of the two components is damaged, the damaged component can be disassembled and replaced, thereby achieving the purpose of cost saving.

[0133] In one application scenario, the positioning member 1910 is detachably connected to the positioning plate 1920 by fasteners such as screws. In another application scenario, the positioning member 1910 and the positioning plate 1920 are detachably connected by means of slots and protrusions. In other application scenarios, the positioning member 1910 and the positioning plate 1920 can also be connected by other detachable methods such as gluing, which is not limited here.

[0134] See also Fig.13 The positioning member 1910 includes a first sub-positioning member 1911 , a second sub-positioning member 1912 and a third sub-positioning member 1913 .

[0135] The first sub-positioning member 1911 is used to detachably abut against a reference element (such as the docking block 1800); the second sub-positioning member 1912 is perpendicular to the first sub-positioning member 1911 and connected to the side of the first sub-positioning member 1911 away from the reference element; the third sub-positioning member 1913 is perpendicular to the second sub-positioning member 1912 and connected to the side of the second sub-positioning member 1912 away from the first sub-positioning member 1911, wherein the positioning plate 1920 abuts against the side of the third sub-positioning member 1913.

[0136] In one application scenario, the first sub-positioning member 1911 is detachably connected to the second sub-positioning member 1912, and the second sub-positioning member 1912 is detachably connected to the third sub-positioning member 1913. Similar to the above, the detachability can be achieved by fastening elements such as screws, or by matching slots and bumps.

[0137] In order to facilitate the positioning of the positioning assembly 1900, the side of the first sub-positioning member 1911 that abuts against the reference element is provided with a notch that matches the reference element (for example, the connecting block 1800), and the side of the third sub-positioning member 1913 that abuts against the positioning plate 1920 is provided with a notch that matches the positioning plate 1920. In order to distinguish the two notches, the notch on the first sub-positioning member 1911 is defined as the first notch 19111, and the notch on the third sub-positioning member 1913 is defined as the second notch 19131.

[0138] Specifically, when the first sub-positioning member 1911 abuts against the reference element, at least a portion of the reference element fits in the first notch 19111 , and when the third sub-positioning member 1913 is connected to the positioning plate 1920 , at least a portion of the positioning plate 1920 fits in the second notch 19131 .

[0139] In other embodiments, the mounting assembly 1900 may be provided with both the first notch 19111 and the second notch 19131 , or may be provided with only one of them.

[0140] Specifically, when positioning is performed using the positioning assembly 1900 , the positioning member 1910 is first fitted onto the reference element through the first notch 19111 , and then the positioning plate 1920 is fitted onto the positioning member 1910 through the second notch 19131 .

[0141] For ease of processing, the first notch 19111 and the second notch 19131 on the first sub-positioning member 1911 and the third sub-positioning member 1913 are both right-angled notches. Of course, in other embodiments, the first notch 19111 and the second notch 19131 may also be other anisotropic notches, depending on the shape of the reference element and the positioning plate 1920, and are not limited here.

[0142] In other embodiments, the positioning assembly 1900 can not only help install the second imaging device, but also help install other components. In other words, the positioning assembly 1900 can also be used in other fields, which is not limited here.

[0143] In this embodiment, also for the consideration of imaging quality, the circuit board detection device 1000 further includes a second light source (not shown) used in conjunction with the second imaging device. In one application scenario, the second light source is a coaxial light source.

[0144] See also Fig.14 The circuit board detection device 1000 also includes an imaging mounting plate 1010, and the imaging mounting plate 1010 is used to install the imaging device.

[0145] A plurality of different imaging mounting parts 1011 are arranged on the mounting surface of the imaging mounting plate 1010, and each imaging mounting part 1011 is matched with a corresponding type of imaging device so that different types of imaging devices can be mounted and fixed on the imaging mounting plate 1010 through different imaging mounting parts 1011, wherein any two different imaging mounting parts 1011 have a partially overlapping area.

[0146] In the prior art, manufacturers of various imaging devices only adapt mounting plates suitable for their own imaging device brands, which results in the need to dismantle the original mounting plates during adjustment of the imaging device, making the entire process complicated.

[0147] In the present embodiment, the imaging mounting plate 1010 is provided with different imaging mounting parts 1011, and different imaging devices can select matching imaging mounting parts 1011 to be installed on the imaging mounting plate 1010, that is, one imaging mounting plate 1010 can be simultaneously applicable to different types of imaging devices, realizing "one plate for multiple uses". Therefore, in the process of replacing the imaging device, there is no need to disassemble the original imaging mounting plate 1010, but only the imaging device needs to be directly disassembled, which is convenient for operation. Moreover, when purchasing materials, only one imaging mounting plate 1010 needs to be purchased for different types of imaging devices, which can reduce production costs.

[0148] At the same time, any two different imaging mounting parts 1011 have a partially overlapping area, which can reduce the surface area of ​​the entire imaging mounting plate 1010, reduce the space occupied by the imaging mounting plate 1010, and ultimately reduce the volume of the circuit board detection device 1000.

[0149] Continue reading Fig.14 The mounting surface of the imaging mounting plate 1010 is provided with a plurality of first mounting holes 10111 of different specifications, and the area defined by the first mounting holes 10111 of each specification constitutes a corresponding imaging mounting portion 1011 .

[0150] In this embodiment, the first mounting hole 10111 is a through hole. When installing the imaging device, a fastener such as a screw is passed through the corresponding first mounting hole 10111 to lock the imaging device on the imaging mounting plate 1010. In other embodiments, the first mounting hole 10111 may also be a blind hole. In this case, the imaging device may be directly clamped in the corresponding blind hole during installation. In other embodiments, the imaging mounting portion 1011 may also be other structures, which are not limited here.

[0151] In one application scenario, the aperture sizes of first mounting holes 10111 of different specifications are different. For example, the aperture sizes of some first mounting holes 10111 are 5.5 mm, while the aperture sizes of some first mounting holes 10111 are 6.5 mm.

[0152] At this time, the first mounting holes 10111 with different apertures are used to install different types of imaging devices. At this time, the imaging mounting parts 1011 for installing different types of imaging devices do not include the same first mounting hole 10111.

[0153] In another application scenario, the shapes or areas of the regions defined by the first mounting holes 10111 of different specifications are different.

[0154] Different from the above application scenario, the imaging installation part 1011 for installing different types of imaging devices may include the same first installation hole 10111. Fig.15As shown, the first mounting hole 10111 labeled 1 is used to install the first type of imaging device, the first mounting hole 10111 labeled 2 is used to install the second type of imaging device, the first mounting hole 10111 labeled 3 is used to install the third type of imaging device, and the first mounting hole 10111 labeled 4 is used to install the fourth type of imaging device, wherein the imaging mounting portion 1011 for installing the third type of imaging device can include a first mounting hole 10111 that is the same as the imaging mounting portion 1011 for installing the second type of imaging device.

[0155] Meanwhile, in the present embodiment, each specification of the first mounting holes 10111 includes four first mounting holes 10111 of the same specification or three first mounting holes 10111 of the same specification.

[0156] For example, Fig.15 In the embodiment, the imaging mounting portion 1011 for mounting the first type of imaging device includes four first mounting holes 10111 of the same specification, while the imaging mounting portion 1011 for mounting the fourth type of imaging device includes three first mounting holes 10111 of the same specification.

[0157] Continue reading Fig.14 A plurality of second mounting holes 10112 are provided on the side of the imaging mounting plate 1010 , wherein the imaging mounting plate 1010 can be detachably mounted on other imaging mounting plates 1010 or the slide rail fixing plate through the second mounting holes 10112 .

[0158] In one application scenario, combined with Fig.16 and Fig.17 The imaging mounting plate 1010, the slide rail fixing plate 1020 and the slider 1030 cooperate to install the imaging device. During the assembly process, the slider 1030 and the slide rail fixing plate 1020 are first connected, and then the imaging mounting plate 1010 is installed on the side of the slide rail fixing plate 1020 away from the slider 1030. During the installation of the imaging mounting plate 1010, fasteners such as screws are used to pass through the slide rail fixing plate 1020 and extend into the second mounting hole 10112, so as to lock the slide rail fixing plate 1020 and the imaging mounting plate 1010.

[0159] In other application scenarios, when the imaging device needs to be installed in other places, the imaging mounting plate 1010 can also be installed on another imaging mounting plate 1010 through the second mounting hole 10112 .

[0160] Continue reading Fig.14A plurality of third mounting holes 10113 are further provided on the mounting surface of the imaging mounting plate 1010, and the imaging mounting plate 1010 can be detachably mounted together with the second mounting holes 10112 on the second imaging mounting plate 2010 through the third mounting holes 10113, so that the imaging mounting plate 1010 is vertically mounted on the second imaging mounting plate 2010, wherein the imaging mounting plate 1010 and the second imaging mounting plate 2010 have the same structure.

[0161] For an imaging device having a mounting portion on only one side, when it is required to be rotated 90 degrees, two imaging mounting plates 1010 are required to be used together. At this time, the vertical connection of the two imaging mounting plates 1010 is achieved through the second mounting hole 10112 and the third mounting hole 10113.

[0162] Specifically, combined Fig.18 and Fig.19 The two imaging mounting plates 1010, the slide rail fixing plate 1020 and the slider 1030 cooperate to mount the imaging device. At this time, the imaging device can be mounted from Fig.17 Adjust the status to Fig.19 state, that is, a 90-degree rotation is achieved.

[0163] In one application scenario, the number of the third mounting holes 10113 is multiple, and the multiple third mounting holes 10113 are distributed on two opposite edges of the imaging mounting plate 1010, and the number of the third mounting holes 10113 set on each edge of the imaging mounting plate 1010 is also multiple, wherein two third mounting holes 10113 respectively located on the two edges are set as a group (for example Fig.14 There are four groups), when two imaging mounting plates 1010 are connected, the connection is achieved through a group of third mounting holes 10113 to ensure the stability of the connection between the two imaging mounting plates 1010.

[0164] Meanwhile, corresponding to different types of imaging devices, two third mounting holes 10113 matching the size of the imaging devices can be selected to realize vertical connection of the two imaging mounting plates 1010 .

[0165] It should be noted that one imaging mounting plate 1010 can be used to install an imaging device alone, or it can be used in conjunction with a slide rail fixing plate 1020 and a slider 1030 to install an imaging device, or two imaging mounting plates 1010 can be used in conjunction with a slide rail fixing plate 1020 and a slider 1030 to install an imaging device.

[0166] Specifically, the present application also provides a mounting and fixing device for mounting and fixing an imaging device, which includes, in addition to an imaging mounting plate 1010, a slide rail fixing plate 1020 and a slider 1030 in an application scenario. Fig.16As shown, the imaging mounting plate 1010 is vertically and detachably mounted on the first fixing plate surface 10201 of the slide rail fixing plate 1020 through the second mounting hole 10112, and the slider 1030 is disposed on the second fixing plate surface 10202 of the slide rail fixing plate 1020, wherein the first fixing plate surface 10201 and the second fixing plate surface 10202 are disposed opposite to each other. In another application scenario, different from the above application scenario, the number of the imaging mounting plates 1010 is two, such as Fig.18 and Fig.19 As shown, an imaging device is mounted on an imaging mounting plate 1010, and the imaging mounting plate 1010 realizes vertical connection between the two imaging mounting plates 1010 through a second mounting hole 10112 and a third mounting hole 10113 on a second imaging mounting plate 2010 (with the same structure as the imaging mounting plate 1010). At the same time, the imaging mounting plate 1010 on which the imaging device is not mounted, i.e., the second imaging mounting plate 1010, is mounted on a first fixed plate surface 10201 of a slide rail fixed plate 1020 through a second mounting hole 10112 thereon, and a slider 1030 is mounted on a second fixed plate surface 10202 of the slide rail fixed plate 1020.

[0167] The imaging device can be installed on the second imaging mounting rail 1214 mentioned above through the mounting and fixing device of the present application. Specifically, in one application scenario, the slider 1030 and the second imaging mounting slider 1215 mentioned above are the same component. At this time, before installing the imaging device, the slide rail fixing plate 1020 is in a connected state with the second slider, and the imaging mounting plate 1010 is also in a connected state with the slide rail fixing plate 1020. Therefore, when installing the imaging device, it is only necessary to directly connect the imaging device to the imaging mounting plate 1010, and when replacing it later, due to the versatility of the imaging mounting plate 1010, there is no need to disassemble the imaging mounting plate 1010. In another application scenario, the slider 1030 is not the same component as the second imaging mounting slider 1215 mentioned above. In this case, before installing the imaging device, the slider 1030 is first installed on the second imaging mounting slider 1215, and then the slide rail fixing plate 1020 is installed on the slider 1030, and the imaging mounting plate 1010 is installed on the slide rail fixing plate 1020. Thereafter, when installing the imaging device, the imaging device is connected to the imaging mounting plate 1010.

[0168] Among them, the apertures of the first mounting hole 10111, the second mounting hole 10112 and the third mounting hole 10113 may be the same or different, and there is no limitation here.

[0169] Continue reading Figure 2 The circuit board detection device 1000 also includes a first cover plate 1040 and a second cover plate 1050 .

[0170] The first cover plate 1040 connects the two first connecting members 1120. Specifically, the first cover plate 1040 is formed by splicing a plurality of sub-cover plates (not shown). After completing the switching of the imaging mounting assembly 1200 at the imaging location 1101, the first cover plate 1040 is installed between the two first connecting members 1120 to prevent the first light source 1700 installed on the light source mounting assembly 1600 and the first imaging device installed on the imaging mounting assembly 1200 located at the imaging location 1101 from inhaling too much dust.

[0171] The second cover plate 1050 is connected to the imaging mounting assembly 1200 which is not at the imaging position 1101, and is used to prevent the imaging device mounted on the imaging mounting assembly 1200 from inhaling too much dust, for example, Figure 2 In an application scenario, when the first imaging mounting assembly 1210 is not at the imaging position 1101 , the second cover plate 1050 is connected to the first imaging mounting assembly 1210 .

[0172] Each time the imaging installation component 1200 located at the imaging position 1101 is switched, the first cover plate 1040 and the second cover plate 1050 are first removed, and then the imaging installation component 1200 is switched. After the switching is completed, the first cover plate 1040 and the second cover plate 1050 are installed at the corresponding positions.

[0173] In other implementations, the circuit board detection device 1000 may include only one of the first cover plate 1040 and the second cover plate 1050 , which is not limited herein.

[0174] Continue reading Figure 1 The circuit board detection device 1000 also includes a shell 1060 .

[0175] The housing 1060 is used to enclose all other components to prevent dust and reduce damage to operators caused by strong light when the imaging device is imaging.

[0176] In one application scenario, the housing 1060 may include a plurality of acrylic panels, which are detachably connected to form the housing 1060. In this application scenario, the positions of the plurality of acrylic panels may be relatively adjusted. Specifically, Fig. 20 and Fig.21 As shown, the first acrylic plate 1061 and the second acrylic plate 1062 are detachably connected (for example, detachably connected by screws 1063). When the relative position of the first acrylic plate 1061 and the second acrylic plate 1062 is changed from Fig. 20 Adjust to Fig.21 When the device 1000 is in the overlapped state (i.e., the area of ​​the overlapped portion of the two is reduced), the height of the circuit board detection device 1000 changes, thereby meeting different detection requirements in different application scenarios and achieving the purpose of saving production costs.

[0177] It should be noted that, in this embodiment, the imaging installation component 1200, the light source installation component 1600, the positioning component 1900 and the imaging installation plate 1010 may not exist in the circuit board detection device 1000 at the same time. For example, the circuit board detection device 1000 may only include the imaging installation component 1200. At this time, the component for installing the first light source 1700 may only install one type of first light source 1700. When installing the second imaging device, other auxiliary tools are used for installation, and when installing the imaging device on the imaging installation component 1200, it can be installed in a traditional way.

[0178] In order to further understand the circuit board detection device 1000 in this embodiment, Figures 1 to 22 The working process of the circuit board detection device 1000 of the present application is described in detail.

[0179] exist Fig. 22 In the application scenario, considering the layout of the circuit board A, the second imaging installation component 1220 is pre-adjusted to be located at the imaging location 1101, and two first imaging devices B are installed on the second imaging installation component 1120. At the same time, a first light source 1700 of a suitable size is installed on the first light source mounting plate 1610. At this time, the first imaging installation component 1210 is not located at the imaging location 1101, but is in an idle state, and the first imaging device B does not need to be installed thereon.

[0180] When the circuit board detection device 1000 is working, the second imaging device C installed on the positioning component 1900 first images the circuit board A transported by the two parallel tracks 1310. When there are marking points of the circuit board A in the image obtained by the second imaging device C, the trigger controller controls the two first imaging devices B located at the imaging position 1101 to image the circuit board A. It can be understood that the first imaging device B and the second imaging device C respectively image the two opposite surfaces of the circuit board A.

[0181] Subsequently, the images obtained by the two first imaging devices B are analyzed using a visual algorithm to ultimately determine whether there are defects on the circuit board A.

[0182] When a new circuit board A needs to be inspected, if it is considered that the pattern of circuit board A only needs to be imaged by a first imaging device B, firstly, the first cover plate 1040 and the second cover plate 1050 are disassembled, and then the two second connecting members 1410 are separated from the two first connecting members 1120 respectively by disassembling the bending member 1500, and then the two second connecting members 1410 are flipped 180 degrees to adjust the first imaging mounting assembly 1210 to the imaging position 1101, and then the two second connecting members 1410 and the two first connecting members 1120 are reconnected by the bending member 1500, and finally the first cover plate 1041 and the second cover plate 1050 are reinstalled.

[0183] Then, a first imaging device B is installed on the first imaging mounting assembly 1210 , and at the same time, the original first light source 1700 is removed from the first light source mounting plate 1610 , and a suitable first light source 1700 is reinstalled on the first light source mounting plate 1610 .

[0184] After the circuit board detection device 1000 is adjusted, the new circuit board A is detected.

[0185] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
