The detection bracket 1100 is detachably mounted on a transportation path 1300 of the circuit board, wherein an imaging part 1101 is arranged in a space region surrounded by the detection bracket 1100.

In the present embodiment, as shown in fig. 2, two rails 1310 arranged in parallel are used to cooperate with the transport circuit board a, and the detection bracket 1100 is detachably mounted on the two rails 1310, when the transport path 1300 is formed between the two parallel rails 1310, and the extending direction of the transport path 1300 coincides with the extending direction of the two rails 1310, when the detection bracket 1100 is arranged on the two rails 1310 to construct a space region at one side of the transport path 1300.

Specifically, when the circuit board a on the transport path 1300 needs to be inspected, the inspection bracket 1100 is mounted on the two rails 1310, and when the circuit board a does not need to be inspected, the inspection bracket 1100 may be removed.

Of course, in other embodiments, the two rails 1310 for transporting the circuit board a may be disposed in non-parallel, or the circuit board a may be transported in other manners, such as in a conveyor manner, and the detection bracket 1100 may be disposed adjacent to the conveyor, and in summary, the application is not limited as to how the detection bracket 1100 is disposed on the transport path 1300.

Meanwhile, the imaging site 1101 may be a specific position point or a position range, which is located in a space region surrounded by the detection frame 1100.

The number of the imaging installation assemblies 1200 is at least two, for example, two, five or more (the number of the imaging installation assemblies 1200 is illustrated as two in the drawings), and each imaging installation assembly 1200 is used for installing a different number of imaging devices, wherein the imaging devices may be a common camera, a CCD camera or other devices with imaging functions.

At least two of the imaging mount assemblies 1200 are adjustably positionable on the inspection stand 1100, and each of the imaging mount assemblies 1200 is adjustable to the imaging station 1101.

While the controller controls the imaging device mounted on the imaging mount assembly 1200 located at the imaging station 1101 to image the circuit board. That is, when the circuit board needs to be imaged by the imaging device on one imaging installation assembly 1200, the imaging installation assembly 1200 needs to be adjusted to the imaging place 1101, wherein when the imaging device is located at the imaging place 1101, the imaging view of the imaging device is not blocked, and the quality of final imaging can be ensured.

Specifically, the circuit boards a of different types have different imaging requirements, for example, some circuit boards a include only one circuit board unit, and some circuit boards a include a plurality of circuit board units, or two circuit boards a including only one circuit board unit are different in size, and at this time, because the imaging field of view is limited, it is difficult to satisfy multiple imaging requirements at the same time, and therefore, different numbers of imaging devices need to be set corresponding to the circuit boards a of different types. In this embodiment, since at least two imaging installation assemblies 1200 respectively used for installing 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 assemblies 1200 capable of installing a corresponding number of imaging devices can be adjusted to the imaging position 1101, and a corresponding number of imaging devices are installed on the imaging installation assembly 1200, that is, the circuit board detection apparatus 1000 in this embodiment can simultaneously meet the detection requirements of circuit boards a of multiple types, compared with the prior art in which only one type of circuit board a can be detected by one machine, the cost of this embodiment can be greatly reduced.

Referring to fig. 3 and 4, the circuit board inspection apparatus 1000 further includes a connection assembly 1400.

The connecting assembly 1400 is disposed on the detecting bracket 1100 with a position adjustable, wherein at least two imaging installation assemblies 1200 are respectively connected to the connecting assembly 1400, and the at least two imaging installation assemblies 1200 are respectively adjustable to the imaging position 1101 along with the position adjustment of the connecting assembly 1400 relative to the detecting bracket 1100.

Specifically, by means of the above arrangement, the positions of the plurality of imaging installation assemblies 1200 can be adjusted simultaneously by adjusting the positions of the connection assembly 1400, and when a certain imaging installation assembly 1200 is required to be adjusted to the imaging place 1101, the position of the connection assembly 1400 relative to the detection support 1100 is correspondingly adjusted, so that the positions of at least two imaging installation assemblies 1200 do not need to be adjusted respectively, that is, when a certain imaging installation assembly 1200 is required to be adjusted to the imaging place 1101, the position of the connection assembly 1400 can be directly adjusted, which is convenient and fast.

In an application scenario, the connection assembly 1400 is rotatably connected to the detection bracket 1100 to be position-adjustable on the detection bracket 1100, and at this time, when a certain imaging installation assembly 1200 needs to be adjusted to the imaging position 1101, the connection assembly 1400 only needs to be rotated by a proper angle relative to the detection bracket 1100.

In another application scenario, the connection assembly 1400 is slidably connected to the detection frame 1100 to be adjustably disposed on the detection frame 1100, and when a certain imaging installation assembly 1200 needs to be adjusted to the imaging position 1101, the connection assembly 1400 only needs to be slid to a proper position relative to the detection frame 1100.

In summary, the present application is not limited with respect to how the connection assembly 1400 can be positionally adjustably disposed on the test stand 1100.

With continued reference to fig. 3, the detecting bracket 1100 includes four supporting members 1110 and two first connecting members 1120, the four supporting members 1110 are symmetrically erected on two rails 1310 for transporting the circuit board a in groups of two, and the two first connecting members 1120 are respectively connected to the two supporting members 1110 erected on the same rail 1310.

Specifically, the arrangement of four supporting members 1110 and two first connecting members 1120 can ensure the stability of the inspection stand 1100. The supporting member 1110 and the first connecting member 1120 are both straight plate-shaped structures, and in other embodiments, the supporting member 1110 and the first connecting member 1120 may also be other structures such as a round bar-shaped structure, which is not limited herein.

In other embodiments, the number of the supporting members 1110 may be more than 4, and the number of the first connecting members 1120 may be more than two, which is not limited herein.

In an application scenario, in order to adjust the distance between two supporting members 1110 disposed on the same rail 1310, the first connecting member 1120 is provided with a plurality of connecting portions 1121 arranged at intervals along the extending direction thereof, the two supporting members 1110 are fixed on the first connecting member 1120 in a position-adjustable manner by the plurality of connecting portions 1121, wherein the connecting portions 1121 may be through holes, and when the distance between the two supporting members 1110 disposed on the same rail 1310 needs to be adjusted, the supporting members 1110 and the first connecting member 1120 are fastened by fastening members such as screws through the corresponding through holes.

With continued reference to fig. 3 and 4, the connecting assembly 1400 includes two second connecting members 1410, and the two second connecting members 1410 are respectively rotatably connected to the two first connecting members 1120, so that the connecting assembly 1400 is rotatably connected to the detecting bracket 1100, wherein at least two imaging installation assemblies 1200 are simultaneously connected to the two second connecting members 1410.

Specifically, each imaging mount assembly 1200 is coupled to two second connectors 1410, wherein the two second connectors 1410 ensure the mounting fixity of the imaging mount assembly 1200 and the smoothness of the position adjustment process compared to one second connector 1410.

Meanwhile, the two second connecting pieces 1410 are located on the same horizontal line relative to the rotating shaft of the first connecting piece 1120, the number of the at least two imaging installation assemblies 1200 is two, and the two imaging installation assemblies 1200 are respectively connected with the end parts of the two second connecting pieces 1410 close to each other. For convenience of illustration, the two imaging mount assemblies 1200 are defined as a first imaging mount assembly 1210 and a second imaging mount assembly 1220, respectively, and in an application scenario, the first imaging mount assembly 1210 is capable of mounting one imaging device and the second imaging mount assembly 1220 is capable of mounting two imaging devices.

At this time, when the imaging installation assembly 1200 at the imaging site 1101 needs to be switched, the two second connecting members 1410 are rotated together relative to the detecting bracket 1100, so that the first imaging installation assembly 1210 at the imaging site 1101 can be switched to the second imaging installation assembly 1220, or the second imaging installation assembly 1220 at the imaging site 1101 can be switched to the first imaging installation assembly 1210.

In this embodiment, as shown in fig. 3, the second connecting members 1410 are in a straight plate structure, and at this time, the two second connecting members 1410 rotate together 180 degrees relative to the detecting bracket 1100 to complete the switching of the imaging installation assembly 1200 located at the imaging position 1101, and at this time, the controller controls the imaging device located on the imaging installation assembly 1200 installed below to image the circuit board, that is, at this time, the imaging position 1101 is the position range where the second imaging installation assembly 1220 is located in fig. 3.

In other embodiments, the connecting assembly 1400 may include only one second connecting member 1410, and in this case, one second connecting member 1410 may be rotatably connected to two first connecting members 1120 at the same time, or only one first connecting member 1120 may be rotatably connected, and the first image mounting assembly 1210 and the second image mounting assembly 1220 are connected to both ends of the second connecting member 1410, respectively.

Referring to fig. 4 and 5, each of the first imaging mount assembly 1210 and the second imaging mount assembly 1220 includes an imaging mount back 1211, a first imaging mount sled 1212, and a first imaging mount slide 1213.

The imaging installation back plate 1211 comprises a first back plate surface 12111 and a second back plate surface 12112 which are arranged oppositely, and one end of the imaging installation back plate 1211 is fixedly connected with a second connecting piece 1410 for installing the imaging device; the first imaging mounting rail 1212 is disposed on a first back plate surface 12111 of the imaging mounting back plate 1211, the first imaging mounting slider 1213 is slidably disposed on the first imaging mounting rail 1212 and is fixedly connected to the other second connecting member 1410, and when the distance between the two second connecting members 1410 is adjusted, the first imaging mounting slider 1213 slides along the first imaging mounting rail 1212.

Specifically, for circuit boards a of different models, the size is different, and the spacing between the two rails 1310 for transportation is also different. It can be understood that when the distance between the two rails 1310 is different, the distance between the two second connecting members 1410 is required to be changed, and therefore, in order to enable the circuit board a detection apparatus 1000 to meet the detection requirements of circuit boards a of different models, the imaging mounting back 1211, the first imaging mounting rail 1212 and the first imaging mounting slider 1213 are provided, so that not only the imaging device can be mounted, but also the distance between the two second connecting members 1410 can be ensured to be adjustable.

With continued reference to fig. 4 and 5, the first and second imaging mount assemblies 1210, 1220 further include second imaging mount slide rails 1214 and second imaging mount slides 1215.

The second imaging mounting sled 1214 is disposed on a second backplane surface 12112 of the imaging mounting backplane 1211; a second imaging mount slider 1215 is slidably disposed on the second imaging mount slide 1214 for mounting the imaging device and sliding the imaging device along the second imaging mount slide 1214.

Specifically, when the position of the imaging device on the imaging mounting back-plate 1211 needs to be adjusted, the second imaging mounting slide 1215 slides relative to the second imaging mounting slide 1214, so as to drive the imaging device to slide, and the imaging field of view of the imaging device changes.

In one application scenario, second imaging mount slide 1214 is an electrically controlled slide that can control the distance second imaging mount slide 1215 slides.

Wherein one second imaging mount slide 1215 is mounted on each second imaging mount slide 1214 and one imaging device is mounted on each second imaging mount slide 1215, such that, in one application scenario, as shown in fig. 5, the first imaging mount assembly 1210 includes one second imaging mount slide 1214 and the second imaging mount assembly 1220 includes two second imaging mount slides 1214.

In other embodiments, the second imaging mount slide 1214 and the second imaging mount slider 1215 may not be provided, but the imaging device may be mounted directly on the imaging mount back 1211.

Referring to fig. 3, two second connectors 1410 are detachably connected to two first connectors 1120, respectively.

Specifically, when the imaging installation assembly 1200 at the imaging position 1101 needs to be switched, the two second connecting pieces 1410 are separated from the two first connecting pieces 1120 respectively, and then the two second connecting pieces 1410 are turned over by 180 degrees, and at this time, the positions of the first imaging installation assembly 1210 and the second imaging installation assembly 1220 are exchanged, so that the switching of the imaging installation assembly 1200 at the imaging position 1101 is realized.

In other embodiments, the connection between the two second connectors 1410 and the two first connectors 1120 may also be non-detachable. For example, the two second connecting members 1410 are respectively rotatably connected to the two first connecting members 1120 through a rotating shaft, which prevents the second connecting members 1410 from being separated from the first connecting members 1120, but during the adjustment process, the rotating shaft can be released to rotate the second connecting members 1410 relative to the first connecting members 1120 around the rotating shaft, and the rotating shaft can be locked to fix the second connecting members 1410 relative to the first connecting members 1120, so that when the imaging installation assembly 1200 at the imaging site 1101 needs to be switched, the rotating shaft can be released first and then locked.

In summary, the application is not limited with respect to whether the second connecting element 1410 can be separated from the first connecting element 1120.

Referring to fig. 3 and 4, the circuit board detection apparatus 1000 further includes a bending member 1500.

The number of the bending member 1500 is two, such that two second connecting members 1410 are detachably connected to two first connecting members 1120, the bending member 1500 specifically includes a first connecting plate 1510 and a second connecting plate 1520 connected at a certain angle (e.g., 90 degrees), the first connecting plate 1510 and the second connecting member 1410 are connected, the second connecting plate 1520 is connected to the first connecting member 1120, wherein the bending member 1500 is detachably connected to at least one of the second connecting member 1410 and the first connecting member 1120.

In an application scene, when rotating second connecting piece 1410, will bend 1500 and first connecting piece 1120 separation, then overturn second connecting piece 1410, then will bend 1500 and first connecting piece 1120 reconnection can, whole rotation process convenient and fast.

In other application scenarios, when the second connecting piece 1410 is rotated, the bending piece 1500 is separated from the second connecting piece 1410, then the second connecting piece 1410 is turned over, and then the bending piece 1500 is reconnected with the second connecting piece 1410.

In an application scenario, a plurality of through holes are disposed on the first connecting plate 1510 and the second connecting plate 1520, and the bending member 1500 is connected to the second connecting member 1410 and the first connecting member 1120 respectively by a screw locking method.

In this embodiment, the second link 1410 is adjustable in length.

Specifically, when switching the imaging installation assembly 1200 located at the imaging site 1101, the field of view of the imaging apparatus may need to be readjusted because the number of imaging apparatuses installed at the imaging site 1101 changes. Through the adjustable length of second connecting piece 1410, can adjust the height of the imaging device relative circuit board a that is located imaging department 1101 according to different application scenarios, realize adjusting the field of vision of imaging device.

Referring to fig. 4 and 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 image mounting assembly 1210, one end of the second sub-connecting member 1412 is connected to the second image mounting assembly 1220, and the other end of the first sub-connecting member 1411 is adjustably fixed to the second sub-connecting member 1412.

The other end of the first sub-connecting piece 1411 is adjustably fixed on the second sub-connecting piece 1412 to realize the length adjustment of the second connecting piece 1410.

In an application scenario, as shown in fig. 4, a plurality of first through holes 14111 are disposed on each of the first sub-connector 1411 and the second sub-connector 1412, and are spaced apart from each other along the extending direction, so that the other end of the first sub-connector 1411 is fixed on the second sub-connector 1412 in a position-adjustable manner.

Specifically, when the field of view of the image forming apparatus needs to be adjusted, the first sub-link 1411 and the second sub-link 1412 are locked together by fastening members, such as screws, through the corresponding first through holes 14111.

In other embodiments, the other end of the first sub-link 1411 may be adjustably fixed to the second sub-link 1412 by another structure, for example, the first sub-link 1411 is provided with a convex pillar, the second sub-link 1412 is provided with a plurality of through holes spaced along the extending direction of the first sub-link 1411, and the other end of the first sub-link 1411 may be adjustably fixed to the second sub-link 1412 by passing the convex pillar through different through holes, or the first sub-link 1411 is slidably arranged on the second sub-link 1412 by a sliding rail, and in this case, the first sub-link 1411 can be adjustably fixed to the second sub-link 1412, and in short, the application does not limit the connection mode between the first sub-link 1411 and the second sub-link 1412.

Referring to fig. 6 and 7, the circuit board inspection device 1000 further includes a light source mounting assembly 1600.

In other application scenarios, the plurality of first mounting portions 1601 may include a plurality of through holes and a plurality of slots, or the plurality of first mounting portions 1601 may also be other structures capable of performing a fixing function, and in summary, the present application is not limited to the structure of the first mounting portions 1601 as long as it can enable different types of first light sources 1700 to be mounted on the first light source mounting board 1610.

With reference to fig. 6 and 8, the mounting assembly 1600 further includes a second light source mounting board 1620 and a third light source mounting board 1630.

Because the second imaging device is used for detecting the position of the circuit board a, the mounting position of the second imaging device is extremely important, otherwise, when the mounting position of the second imaging device is deviated, the circuit board a has already arrived at a proper position, but there is no phenomenon of a mark point in an image obtained by the second imaging device, so the embodiment positions the position of the circuit board a through the positioning assembly 1900, and then the second imaging device is mounted according to the positioning of the circuit board a, thereby ensuring that the mounting position of the second imaging device is correct. Specifically, the positioning assembly 1900 includes a positioning member 1910 and a positioning plate 1920.

The first cover 1040 connects the two first connectors 1120, and in particular, the first cover 1040 is formed by splicing a plurality of sub-covers (not shown), and after the switching of the imaging mount assembly 1200 at the imaging site 1101 is completed, the first cover 1040 is mounted between the two first connectors 1120, so as to prevent the first light source 1700 mounted on the light source mount assembly 1600 and the first imaging device mounted on the imaging mount assembly 1200 at the imaging site 1101 from sucking too much dust.

The second cover 1050 is connected to the imaging mount 1200 not at the imaging site 1101 for preventing the imaging device mounted on the imaging mount 1200 from sucking too much dust, for example, in the application scenario of fig. 2, when the first imaging mount 1210 is not at the imaging site 1101, the second cover 1050 is connected to the first imaging mount 1210.

When switching the imaging installation assembly 1200 located at the imaging position 1101, the first cover 1040 and the second cover 1050 are detached, and then the imaging installation assembly 1200 is switched, and after the switching is finished, the first cover 1040 and the second cover 1050 are installed at corresponding positions.

In other embodiments, the circuit board detection apparatus 1000 may include only one of the first cover 1040 and the second cover 1050, which is not limited herein.

With continued reference to fig. 1, the circuit board inspection device 1000 further includes a housing 1060.

The housing 1060 is used to enclose all other components, and serves to prevent dust and reduce glare from injuring the operator when the imaging device is used to image.

In one application scenario, housing 1060 may include a plurality of acrylic plates that are removably coupled to form housing 1060. Meanwhile, in this application scenario, the positions of the plurality of acrylic plates may be relatively adjusted, specifically, as shown in fig. 20 and 21, the first acrylic plate 1061 and the second acrylic plate 1062 are detachably connected (for example, detachably connected by a screw 1063), and when the relative positions of the first acrylic plate 1061 and the second acrylic plate 1062 are adjusted from fig. 20 to the state of fig. 21 (i.e., the area of the overlapping portion of the two is reduced), the height of the circuit board detection apparatus 1000 is changed, so that different detection requirements are met in different application scenarios, and the purpose of saving the production cost is achieved.

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 board 1010 may not exist in the circuit board inspection apparatus 1000 at the same time, for example, the circuit board inspection apparatus 1000 may only include the imaging installation component 1200, and the component for installing the first light source 1700 may only be capable of installing one type of the first light source 1700, and when installing the second imaging device, the second imaging device is installed by using other auxiliary tools, and when installing the imaging device on the imaging installation component 1200, the imaging device may be installed in a conventional manner.

In order to further understand the circuit board detection apparatus 1000 in this embodiment, the operation of the circuit board detection apparatus 1000 of the present application is described in detail below with reference to fig. 1 to fig. 22.

In the application scenario of fig. 22, the second imaging mounting assembly 1220 is adjusted to be located at the imaging site 1101 in advance in consideration of the layout of the circuit board a, and two first imaging devices B are mounted on the second imaging mounting assembly 1120 while the first light source 1700 of a proper size is mounted on the first light source mounting plate 1610, while the first imaging mounting assembly 1210 is not located at the imaging site 1101, which is in an idle state, on which the first imaging device B is not required to be mounted.

When the circuit board detection apparatus 1000 works, the second imaging device C mounted on the positioning assembly 1900 images the circuit board a transported by the two parallel rails 1310, and when the image obtained by the second imaging device C has a mark point of the circuit board a, 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 image two opposite surfaces of the circuit board a respectively.

And subsequently, analyzing the images obtained by the two first imaging devices B by using a visual algorithm, and finally determining whether the circuit board A has defects.

When a new circuit board a needs to be detected, if it is considered that the type of the circuit board a only needs to use one first imaging device B for imaging, the first cover plate 1040 and the second cover plate 1050 are firstly detached, then the two second connecting pieces 1410 are separated from the two first connecting pieces 1120 respectively by detaching the bending piece 1500, then the two second connecting pieces 1410 are turned over by 180 degrees to adjust the first imaging installation assembly 1210 to the imaging position 1101, then the two second connecting pieces 1410 are reconnected with the two first connecting pieces 1120 by the bending piece 1500, and finally the first cover plate 1041 and the second cover plate 1050 are reinstalled.

A first imaging device B is then mounted on the first imaging mounting assembly 1210, and the original first light source 1700 is removed from the first light source mounting plate 1610, and the appropriate first light source 1700 is reinstalled on the first light source mounting plate 1610.

After the circuit board inspection apparatus 1000 is adjusted, a new circuit board a is inspected.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
