[0110] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0111] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0112] Hereinafter, referring to the accompanying drawings, a visual inspection device 100 according to an embodiment of the present invention will be described. The visual inspection device is used to perform defect inspection on a component to be inspected (eg, a PCB board or a PCB board assembly, etc.).

[0113] like Figure 1-Figure 5 As shown, the appearance inspection device 100 includes a shell 8, a loading component 1, a conveying component 4 and a camera component 2. The shell 8 is formed with a loading port 8a. The loading component 1 is arranged at the loading port 8a, and a part of the loading component 1 is located outside the shell 8, and the other part of the loading component 1 is arranged inside the shell 8. The operator or the loading mechanism can load the part of the loading component 1 located outside the shell 8, so that the operator or the loading mechanism has a larger loading space for fast loading, thereby improving the loading efficiency of the appearance inspection device 100.

[0114] The conveying assembly 4 is arranged in the housing 8. The loading assembly 1 is used to convey the piece to be detected toward the conveying assembly 4. For example, the piece to be detected on the loading assembly 1 can be transported to the conveying assembly 4 by a clamping assembly; the conveying assembly 4 is used to convey the piece to be detected along the conveying direction (for example, Figure 3 from left to right in the image).

[0115] The camera component 2 is arranged in the shell 8, and during the transmission of the workpiece to be inspected, the camera component 2 is used to collect image information of the workpiece to be inspected, so that the appearance inspection equipment 100 can detect defects of the workpiece to be inspected through the image information of the workpiece to be inspected. At the same time, the collection process of the camera component 2 will not affect the transmission of the workpiece to be inspected, which is beneficial to ensuring the inspection efficiency of the appearance inspection equipment 100.

[0116] According to the appearance inspection device 100 of the embodiment of the present invention, by arranging a part of the loading component 1 on the outside of the shell 8 and the other part inside the shell 8, the appearance inspection device 100 has sufficient loading space, which is convenient for improving the loading efficiency; and the collection process of the camera component 2 will not affect the transmission of the parts to be inspected, which is convenient for ensuring the inspection efficiency of the appearance inspection device 100.

[0117] In some embodiments of the present invention, Figure 6-Figure 11 As shown, the loading assembly 1 includes a machine body 11, a first loading platform 12 and a second loading platform 13. The first loading platform 12 is disposed on the machine body 11, and the first loading platform 12 is disposed along a first direction (for example, Figure 6 The first loading position (left and right direction) can be moved between the first loading position and the first loading position. At the first loading position, the parts to be detected can be loaded to the first loading platform 12 by the loading mechanism or by the operator. The first loading platform 12 drives the parts to be detected to move to the first loading position, so that the parts to be detected can be transferred from the first loading platform 12 to the second loading platform 13. The first direction is parallel to the conveying direction.

[0118] The second loading platform 13 is disposed on the machine body 11, and the second loading platform 13 is arranged along a second direction (for example, Figure 7 When the first loading platform 12 is located at the first loading position and the second loading platform 13 is located at the second loading position, the first loading platform 12 and the second loading platform 13 move relative to each other to transfer the parts to be inspected on the first loading platform 12 to the second loading platform 13. The first direction and the second direction are perpendicular.

[0119] Obviously, the first loading table 12 can load at the first loading position, and the first loading table 12 can realize the transmission of the parts to be inspected at the first loading position, so that the parts to be inspected are transferred from the first loading table 12 to the second loading table 13; the second loading table 13 can receive the parts to be inspected on the first loading table 12 at the second loading position to realize the loading of the second loading table 13, and the second loading table 13 can realize the loading of the parts to be inspected at the second loading position.

[0120] Therefore, the first loading platform 12 and the second loading platform 13 can be set to move so as to realize continuous loading of the loading assembly 1 and effectively ensure the loading efficiency.

[0121] The feeding method comprises the following steps:

[0122] S1. The second loading platform 13 moves to the second loading position, and the first loading platform 12 drives the to-be-tested parts to move from the first loading position to the first loading position.

[0123] Among them, the order of "the second loading table 13 moves to the second loading position" and "the first loading table 12 drives the to-be-detected piece from the first loading position to the first loading position" in step S1 is not fixed. For example, in step S1, the second loading table 13 can be controlled to move to the second loading position first, and then the first loading table 12 can be controlled to drive the to-be-detected piece from the first loading position to the first loading position, or the first loading table 12 can be controlled to drive the to-be-detected piece from the first loading position to the first loading position first, and then the second loading table 13 can be controlled to move to the second loading position, or the above two processes can be performed simultaneously.

[0124] It can be understood that when the second loading table 13 moves to the second loading position, it corresponds to time t1, and when the first loading table 12 moves to the first loading position, it corresponds to time t2. Time t1 may be earlier than time t2, or time t2 may be earlier than time t1, or time t1 and time t2 may be the same time.

[0125] S2, the second loading platform 13 loads materials, and the first loading platform 12 is loaded; the above steps S1-S2 are repeated until the loading assembly 10 stops running.

[0126] Among them, in step S2, the implementation time period of loading on the second loading station 13 at least partially overlaps with the implementation time period of loading on the first loading station 12, that is, the time interval corresponding to the loading process of the second loading station 13 and the time interval corresponding to the loading process of the first loading station 12 have an overlapping intersection, so that the loading time of the second loading station 13 is used to load the first loading station 12, which can effectively save the loading time of the loading component 1 and improve the loading efficiency. At the same time, when the second loading station 13 needs to be loaded, the first loading station 12 can provide the parts to be inspected more quickly. When the second loading station 13 needs to be loaded, the first loading station 12 has completed loading, so that the first loading station 12 can provide the parts to be inspected to the second loading station 13 in time, which is conducive to realizing continuous loading of the loading component 1 and further improving the loading efficiency.

[0127] The loading of the second loading station 13 includes: the second loading station 13 moves toward the second loading position to take away the parts to be inspected, and after the loading is completed, the second loading station 13 moves to the second loading position again, then the loading process of the second loading station 13 can start from the second loading station 13 taking away the parts to be inspected from the first loading station 12, until the second loading station 13 moves to the second loading position again. The loading of the first loading station 12 includes: the first loading station 12 moves to the first loading position, and after the loading is completed, the first loading station 12 moves to the first loading position again, then the loading process of the first loading station 12 can start from the second loading station 13 taking away the parts to be inspected and the first loading station 12 moves toward the first loading position, until the first loading station 12 moves to the first loading position again.

[0128] Obviously, if during the loading process of the second loading platform 13, the second loading platform 13 moves to the second loading position again corresponding to time t3, and during the loading process of the first loading platform 12, the first loading platform 12 starts to move toward the first loading position corresponding to time t4, since the implementation time period of loading on the second loading platform 13 at least partially overlaps with the implementation time period of loading on the first loading platform 12, then time t4 should be earlier than time t3.

[0129] In addition, if during the loading process of the second loading table 13, the second loading table 13 takes away the parts to be inspected from the first loading table 12 corresponding to time t5, then time t5 is earlier than time t3, and during the loading process of the first loading table 12, the first loading table 12 moves to the first loading position again corresponding to time t6, then time t6 is later than time t4, and time t4 is not earlier than time t5.

[0130] When the implementation time period of loading on the second loading station 13 only partially overlaps with the implementation time period of loading on the first loading station 12, then (1) moment t6 is later than moment t3, and moment t4 is any moment between moment t5 and moment t3 (excluding moment t5 and moment t3), that is, moment 4 is later than moment 5 and earlier than moment t3; or, (2) moment t6 is later than moment t3, and moment t4 and moment t5 are the same moment; or, (3) moment t4 is later than moment t5 and earlier than moment t3, and moment t6 is any moment between moment t5 and moment t3 (excluding moment t5 and moment t3), that is, moment 6 is later than moment t5 and earlier than moment t3; or, (4) moment t4 is later than moment t5 and earlier than moment t3, and moment t6 and moment t5 are the same moment. When the time period for loading materials on the second loading station 13 completely coincides with the time period for loading materials on the first loading station 12 , time t4 is the same as time t5 , and time t6 is the same as time t3 .

[0131] In addition, the moving direction of the second loading platform 13 is perpendicular to the moving direction of the first loading platform 12, so as to ensure that the placement posture of the parts to be inspected remains unchanged during the process of being transferred from the first loading platform 12 to the second loading platform 13, thereby avoiding the parts to be inspected from being deflected by external forces during the above process, thereby affecting the inspection accuracy of the parts to be inspected, and preventing the parts to be inspected from being subjected to the friction applied by the first loading platform 12 and the second loading platform 13, thereby avoiding scratches on the parts to be inspected.

[0132] like Figure 4 and Figure 5 As shown, the second loading platform 13 and the first loading platform 12 are located in the third direction (eg, Figure 4 The same side of the front-to-back direction in the third direction can save the space occupied by the feeding assembly 1 in the third direction, reduce the width of the feeding assembly 1 in the third direction, thereby effectively reducing the width of the appearance inspection device 100 in the third direction, saving the volume and space occupied by the appearance inspection device 100. The third direction is perpendicular to the first direction and the second direction respectively.

[0133] Alternatively, if Figure 1 and Figure 2As shown, the shell 8 is formed with a visual window 8b, which is located on the side of the conveying component 4 in the third direction away from the first loading platform 12 and the second loading platform 13. The operator can observe the inspection status of the parts to be inspected through the visual window 8b, and the loading component 1 will not block the operator's observation line of sight.

[0134] Alternatively, if Figure 1 As shown, the shell 8 is formed with a maintenance port 8c, which is located on the side of the conveying component 4 in the third direction away from the first loading platform 12 and the second loading platform 13. Since the second loading platform 13 and the first loading platform 12 are suitable for being located on the same side of the conveying component 4 in the third direction, it is convenient to effectively reduce the distance between the maintenance port 8c and the conveying component 4, thereby effectively improving the convenience for the operator to inspect the conveying component 4 through the maintenance port 8c, and facilitating the maintenance of the appearance inspection equipment 100.

[0135] Optionally, a detachable shielding plate may be provided at the maintenance port 8c. The shielding plate is installed at the maintenance port 8c to shield the internal structure of the shell 8. The shielding portion may also be detached from the maintenance port 8c to facilitate maintenance by operators.

[0136] For example, in Figure 1 In the example, the shell 8 is formed with a visual window 8b and a maintenance port 8c, both of which are located on the side of the conveying component 4 in the third direction away from the first loading platform 12 and the second loading platform 13, and the visual window 8b can be spaced above the maintenance port 8c.

[0137] In some embodiments, Figure 1 As shown, the housing 8 has a display panel 81 and a control panel. The display panel 81 can display the operating status of the appearance inspection device 100 , and the operator can operate on the control panel to control the operation of the appearance inspection device 100 .

[0138] Alternatively, if Figure 1 As shown, an alarm device 10 is provided on the housing 8 , so that when an abnormality occurs in the operation of the appearance inspection device 100 , the alarm device 10 will sound an alarm and promptly remind the operator to ensure the safe operation of the appearance inspection device 100 .

[0139] In addition, if Figure 2 As shown, a feed opening 8d is also formed on the shell 8, and the appearance inspection device 100 includes a feed opening component 9, which is arranged at the feed opening 8d. In the conveying direction, the feed opening component 9 is arranged at the downstream end of the conveying component 4.

[0140] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 4As shown, at the first loading position, at least part of the first loading platform 12 is located outside the housing 8, so that the loading mechanism or the operator can load the first loading platform 12 to ensure the loading efficiency. The second loading platform 13 can always be located inside the housing 8.

[0141] In some embodiments of the present invention, Figure 6-Figure 10 As shown, the loading assembly 1 also includes a first limit plate 14, which is used to limit the movement of the part to be detected on the first loading platform 12 in the third direction. For example, when the part to be detected is placed on the first loading platform 12, the part to be detected can be stopped against the first limit plate 14 in the third direction, so as to ensure the placement accuracy of the part to be detected on the first loading platform 12 in the third direction, and at the same time, it is easy to achieve the stable placement of the part to be detected on the first loading platform 12, which is conducive to the smooth transmission of the part to be detected.

[0142] The feeding assembly 1 further includes a second limiting plate 15, which is in a shielding position (such as Figure 6-Figure 9 as shown) and avoidance position (as shown Fig.10 When the second limiting plate 15 is in the blocking position, it is movable between the first loading platform 12 and the second limiting plate 15. In the blocking position, the second limiting plate 15 is used to limit the movement of the to-be-detected part on the first loading platform 12 at the first loading position in the first direction. For example, when the first loading platform 12 is located at the first loading position, the to-be-detected part is placed on the first loading platform 12, and the to-be-detected part can be stopped in the first direction by the second limiting plate 15 located at the blocking position, so as to ensure the placement accuracy of the to-be-detected part on the first loading platform 12 in the first direction, and at the same time facilitate to further realize the stable placement of the to-be-detected part on the first loading platform 12, and further realize the stable transmission of the to-be-detected part; in the avoidance position, the second limiting plate 15 avoids the first loading platform 12, that is, when the second limiting plate 15 moves to the avoidance position, the second limiting plate 15 will not interfere with the movement of the first loading platform 12 in the first direction, so as to ensure smooth loading.

[0143] At this time, during the loading process of the first loading platform 12, when the first loading platform 12 is located at the first loading position, the second limit plate 15 moves to the blocking position, and the part to be inspected is placed on the first loading platform 12, and the part to be inspected is stopped against the first limit plate 14 and the second limit plate 15 respectively, so as to ensure the placement accuracy of the part to be inspected on the first loading platform 12; after the loading is completed, the second limit plate 15 moves to the avoidance position, so as to ensure the smooth loading of the first loading platform 12.

[0144] In some embodiments, there are one or more first limiting plates 14, and each first limiting plate 14 is arranged parallel to the first direction; Figure 6-Figure 10As shown, when there are multiple first limit plates 14, the multiple first limit plates 14 can be spaced apart along the third direction. During the loading process of the first loading platform 12, the part to be detected is stopped against one of the first limit plates 14, which is convenient for reducing the placement requirements of the part to be detected and simplifying the loading process while ensuring that the part to be detected is placed stably.

[0145] Optionally, one of the first limiting plates 14 (eg, Figure 6 The front one of the two first limit plates 14 shown is arranged at one end of the first loading platform 12 in the third direction. At this time, the first limit plate 14 can be fixed to the first loading platform 12, and the first limit plate 14 can move with the first loading platform 12, so that during the entire movement process of the first loading platform 12, the first limit plate 14 can limit the movement of the parts to be inspected on the first loading platform 12 in the third direction, which is beneficial to improving the stability of the placement of the parts to be inspected.

[0146] Optionally, one of the first limiting plates 14 (eg, Figure 6 When the front side of the two first limit plates 14 is arranged at one end of the first loading platform 12 in the second direction, the first limit plate 14 can also be fixed to the machine body 11, so that the first limit plate 14 will not move with the first loading platform 12, simplifying the installation of the first limit plate 14, and the length of the first limit plate 14 in the first direction can be set according to the actual application. For example, the length of the first limit plate 14 in the first direction can be less than, equal to, or greater than the moving distance of the first loading platform 12.

[0147] Obviously, the first limiting plate 14 provided at one end of the first loading platform 12 in the third direction may not reduce the loading space of the first loading platform 12, so that the first loading platform 12 is suitable for larger-sized parts to be inspected.

[0148] Alternatively, if Figure 6-Figure 10 As shown, at least one first limiting plate 14 (for example, Figure 6The rear side one of the two first limiting plates 14 shown can move between a mating position and a separation position relative to the first loading platform 12. In the mating position, the first limiting plate 14 is arranged between the two ends of the first loading platform 12 in the third direction, and the first limiting plate 14 divides the loading space of the first loading platform 12 into a plurality of first sub-spaces, and the plurality of first sub-spaces are arranged in sequence along the third direction. At this time, each first sub-space can be respectively stacked with smaller-sized parts to be detected, so that the first loading platform 12 can realize the stacking of multiple piles of smaller-sized parts to be detected, increase the number of smaller-sized parts to be detected placed on the first loading platform 12, and at the same time ensure the placement accuracy of multiple piles of parts to be detected, and ensure stable placement; in the separation position, the first limiting plate 14 is spaced apart from the loading space of the first loading platform 12, and at this time, the first loading platform 12 can be used to place larger-sized parts to be detected, and can also be used to place smaller-sized parts to be detected.

[0149] At this time, before loading the first loading table 12, the at least one first limit plate 14 is controlled to move to the matching position or the separation position according to the size of the part to be inspected, so that the sub-first space divided by the first limit plate 14 corresponding to the matching position can better match the part to be inspected.

[0150] For example, there is one first limit plate 14 that can move relative to the first loading platform 12. When the first loading platform 12 needs to place a larger piece to be detected, the first limit plate 14 can be moved to the separation position; when the first loading platform 12 needs to place a smaller piece to be detected, the first limit plate 14 can be moved to the matching position to increase the number of pieces to be detected. For example, there are two first limit plates 14 that can move relative to the first loading platform 12. At this time, according to the size of the piece to be detected, the two first limit plates 14 are controlled to move to the separation position, or to the matching position, or one of them moves to the separation position and the other moves to the matching position.

[0151] It is understandable that, for the first limit plate 14 that can move between the mating position and the separation position relative to the first loading platform 12, the distance between the first limit plate 14 and the corresponding end of the first loading platform 12 in the third direction can be specifically set according to the size of the part to be detected, for example, in the mating position, the first limit plate 14 can be set corresponding to the middle of the first loading platform 12 in the third direction. If there are multiple first limit plates 14 that can move relative to the first loading platform 12, the mating positions of the multiple first limit plates 14 can be set at intervals along the third direction.

[0152] In addition, for the first limit plate 14 that can move between the mating position and the disengagement position relative to the first loading platform 12, its mating position can always remain unchanged relative to the machine body 11, for example, in the mating position, the first limit plate 14 is fixed to the machine body 11; or, its mating position can be adjustable in a third direction relative to the machine body 11, for example, in the mating position, the first limit plate 14 can be moved along the third direction relative to the machine body 11 to adjust the distance between the first limit plate 14 and the corresponding end of the first loading platform 12, which is beneficial to improving the applicability of the loading component 1.

[0153] Of course, the present application is not limited thereto; in other embodiments, such as Figure 6-Figure 10 As shown, there are multiple first limiting plates 14, and the multiple first limiting plates 14 are arranged at intervals along the third direction, and each first limiting plate 14 is arranged parallel to the first direction, and one of the first limiting plates 14 (for example, Figure 6 The front side one of the two first limiting plates 14 is provided at one end of the first loading platform 12 in the third direction, and the first limiting plate 14 is fixed to the first loading platform 12 or the machine body 11, and at least one of the other first limiting plates 14 (for example, Figure 6 The rear one of the two first limit plates 14 shown can move between a mating position and a separation position relative to the first loading platform 12. In the mating position, the first limit plate 14 is arranged between the two ends of the first loading platform 12 in the second direction, and the first limit plate 14 divides the loading space of the first loading platform 12 into a plurality of first sub-spaces. In the separation position, the first limit plate 14 is spaced apart from the loading space of the first loading platform 12.

[0154] The following description will take the case where there are two first limiting plates 14 as an example. After reading the following technical solution, those skilled in the art will easily understand the solution where there are three or more first limiting plates 14 .

[0155] exist Figure 6 In the example, the two first limit plates 14 are arranged at intervals in the front-to-back direction, the front first limit plate 14 is fixed to the body 1, and the rear first limit plate 14 is detachably connected to the body 1 to achieve movement between the first mating position and the first separation position; when the size of the to-be-detected part is large, the rear first limit plate 14 is removed from the body 1 before the first loading platform 12 is loaded, and the to-be-detected part on the first loading platform 12 can be stopped against the first limit plate 14 on the front side; when the size of the to-be-detected part is small, the rear first limit plate 14 is installed on the body 1 before the first loading platform 12 is loaded, and the to-be-detected part on the first loading platform 12 can be stopped against the first limit plate 14 on the rear side, or a part of it can be stopped against the first limit plate 14 on the front side, and the other part can be stopped against the first limit plate 14 on the rear side, but is not limited to this.

[0156] In some optional embodiments, for the first limit plate 14 that can move between a mating position and a separation position relative to the first loading platform 12, the first limit plate 14 is detachably connected to the body 11 of the loading assembly 10. In the separation position, the first limit plate 14 is detached from the body 11 to ensure that the first limit plate 14 and the loading space of the first loading platform 12 are effectively separated.

[0157] Of course, the arrangement of the first limiting plate 14 that can move between the mating position and the disengaging position is not limited thereto; for example, the first limiting plate 14 is slidably mated or rotationally connected to the body 11 .

[0158] In some embodiments, Figure 6-Figure 10 As shown, the second limit plate 15 can move along the second direction, so the movement of the second limit plate 15 is simple, which is convenient for simplifying the structure of the loading assembly 1. In the shielding position, the second limit plate 15 is located on one side of the first loading platform 12 at the loading position in the first direction. When the first loading platform 12 is at the first loading position and the second limit plate 15 is at the shielding position, the second limit plate 15 is located on one side of the first loading platform 12 in the first direction, so as to ensure that the second limit plate 15 can limit the movement of the inspected part in the first direction.

[0159] In some embodiments, Figure 6 As shown, there are multiple first limit plates 14, and the multiple first limit plates 14 are spaced apart along the second direction, and at least one first limit plate 14 divides the loading space of the first loading platform 12 into multiple first sub-spaces. In the second direction, the distance L1 between the two outermost ones of the multiple first limit plates 14 is smaller than the width L2 of the second limit plate 15, so as to ensure that the second limit plate 15 can limit the parts to be detected in each first sub-space.

[0160] In some embodiments of the present invention, Figure 6-Figure 9 As shown, the loading assembly 1 also includes a third limit plate 16, and the third limit plate 16 is arranged relative to the first limit plate 14 along the first direction, and the third limit plate 16 is used to limit the movement of the part to be detected on the second loading platform 13 in the third direction. For example, when the part to be detected is transferred from the first loading platform 12 to the second loading platform 13, the part to be detected can be stopped against the third limit plate 16 in the third direction, so as to ensure the placement accuracy of the part to be detected on the second loading platform 13 in the third direction, and at the same time, it is convenient to ensure that the part to be detected is stably placed on the second loading platform 13, which is conducive to the smooth transfer of the part to be detected.

[0161] In some embodiments, there are one or more third limiting plates 16, each of which is arranged parallel to the first direction, wherein one of the third limiting plates 16 (for example, Figure 6The front one of the two third limiting plates 16 is arranged at one end of the second loading platform 13 in the third direction. At this time, the third limiting plate 16 can be fixed to the second loading platform 12, and the third limiting plate 16 can move relative to the machine body 11 with the second loading platform 13, so that during the entire movement of the second loading platform 13, the third limiting plate 16 can limit the movement of the to-be-detected parts on the second loading platform 13 in the third direction, which is conducive to improving the stability of the placement of the to-be-detected parts. It can be understood that when there is one third limiting plate 16, the setting of the third limiting plate 16 meets the above setting requirements; when there are multiple third limiting plates 16, the setting of one of the multiple third limiting plates 16 meets the above setting requirements.

[0162] Of course, when one of the third limit plates 16 is arranged at one end of the second loading platform 13 in the third direction, the third limit plate 16 can also be fixed to the body 11 to simplify the installation of the third limit plate 16. At this time, the length of the third limit plate 16 in the second direction can be set according to actual application. For example, the third limit plate 16 is shorter in the second direction, so that the third limit plate 16 can only correspond to the second loading platform 13 in the second loading position. When the second loading platform 13 is in the second loading position, the parts to be inspected can be transferred from the first loading platform 12 to the second loading platform 13, and the third limit plate 16 can limit the movement of the parts to be inspected. After the loading is completed, the second loading platform 13 moves along the second direction relative to the third limit plate 16. Since the second direction is perpendicular to the third direction, the second loading platform 13 is moving and the parts to be inspected are not easy to move in the third direction, and the third limit plate 16 is not needed to continue to limit. For another example, the third limit plate 16 is longer in the second direction, so that the second loading platform 13 always corresponds to the third limit plate 16 during the movement.

[0163] In some other embodiments, there are one or more third limiting plates 16, each of which is arranged parallel to the first direction, and at least one third limiting plate 16 (for example, Figure 6The rear one of the two third limiting plates 16 shown can move between the second matching position and the second separation position relative to the second loading platform 13. In the second matching position, the third limiting plate 16 is arranged between the two ends of the second loading platform 13 in the second direction, and the third limiting plate 16 divides the loading space of the second loading platform 13 into a plurality of second sub-spaces, and the plurality of second sub-spaces are arranged in sequence along the third direction. At this time, each second sub-space can be stacked with smaller-sized parts to be detected, so that the second loading platform 13 can realize the stacking of multiple piles of smaller-sized parts to be detected, increase the number of smaller-sized parts to be detected placed on the second loading platform 13, and at the same time ensure the placement accuracy of multiple piles of parts to be detected, and ensure stable placement; in the second separation position, the third limiting plate 16 is spaced apart from the loading space of the second loading platform 13, and at this time, the second loading platform 13 can be used to place larger-sized parts to be detected, and can also be used to place smaller-sized parts to be detected.

[0164] Therefore, when the first loading table 12 is used to place larger-sized parts to be inspected, the second loading table 13 needs to be able to place larger-sized parts to be inspected, so that the above-mentioned movable third limit plate 16 can be moved to the second separation position; when the first loading table 12 is used to place smaller-sized parts to be inspected, the second loading table 13 needs to be able to place smaller-sized parts to be inspected, so that the above-mentioned movable third limit plate 16 can be moved to the second matching position to increase the number of parts to be inspected.

[0165] It can be understood that, for the third limit plate 16 that can move between the second matching position and the second separation position relative to the second loading platform 13, the distance between the third direction and the corresponding end of the second loading platform 13 can be specifically set according to the size of the part to be detected, for example, in the second matching position, the third limit plate 16 can be set corresponding to the middle of the second loading platform 13 in the third direction. In short, the third limit plate 16 that can move between the second matching position and the second separation position relative to the second loading platform 13 can be set opposite to the first limit plate 14 that can move between the first matching position and the first separation position relative to the first loading platform 12 along the first direction.

[0166] In addition, for the third limit plate 16 that can move between the second mating position and the second separation position relative to the second loading platform 13, its second mating position can always remain unchanged relative to the machine body 11, for example, in the second mating position, the third limit plate 16 is fixed to the machine body 11; or, its second mating position can be adjustable in a third direction relative to the machine body 11, for example, in the second mating position, the third limit plate 16 can be moved along the third direction relative to the machine body 11 to adjust the distance between the third limit plate 16 and the corresponding end of the second loading platform 13, which is beneficial to improving the applicability of the loading component 1.

[0167] Of course, the present application is not limited thereto; in other embodiments, such as Figure 6 As shown, there are multiple third limit plates 16, and the multiple third limit plates 16 are arranged at intervals along the third direction, and each third limit plate 16 is respectively arranged parallel to the first direction, one of the third limit plates 16 is arranged at one end of the second loading platform 13 in the third direction, and the third limit plate 16 is fixed to the second loading platform 13 or the machine body 11, and one of the remaining third limit plates 16 can move between a second matching position and a second separation position relative to the second loading platform 13. In the second matching position, the third limit plate 16 is arranged between the two ends of the second loading platform 13 in the third direction, and the third limit plate 16 divides the loading space of the second loading platform 13 into multiple second sub-spaces. In the second separation position, the third limit plate 16 is spaced apart from the loading space of the second loading platform 13.

[0168] The following description will be made by taking the case where there are two third limiting plates 16 as an example. After reading the following technical solution, those skilled in the art will easily understand the solution where there are three or more third limiting plates 16 .

[0169] exist Figure 6 In the example, two third limit plates 16 are arranged at intervals in the front-to-back direction, the third limit plate 16 on the front side is fixed to the body 11, and the third limit plate 16 on the rear side is detachably connected to the body 11 to achieve movement between the second mating position and the second separation position; when the size of the to-be-detected part is large, before the first loading platform 12 is loaded, the third limit plate 16 on the rear side is removed from the body 11, and the to-be-detected part on the second loading platform 13 can be restricted in movement by the third limit plate 16 on the front side; when the size of the to-be-detected part is small, before the first loading platform 12 is loaded, the third limit plate 16 on the rear side is installed on the body 11, and the to-be-detected part on the second loading platform 12 can be restricted in movement by the third limit plate 16 on the rear side, or a part of it can be restricted in movement by the third limit plate 16 on the front side, and the other part of it can be restricted in movement by the third limit plate 16 on the rear side, but the present invention is not limited thereto.

[0170] It can be understood that, in the description of the present application, the "first limiting plate 14", "second limiting plate 15" and "third limiting plate 16" may all refer to a whole plate, or may be respectively constructed as plates composed of multiple plates.

[0171] In some embodiments, Figure 6-Figure 10As shown, the second direction is the up and down direction, the second loading platform 13 can move from bottom to top toward the conveying component 4, and can also move from top to bottom away from the conveying component 4. When the first loading platform 12 is located at the first loading position and the second loading platform 13 is located at the second loading position, the upper surface of the first loading platform 12 is located above the upper surface of the second loading platform 13. In other words, the height position of the upper surface of the first loading platform 12 is higher than the height position of the upper surface of the second loading platform 13. Therefore, in the process of the first loading platform 12 driving the inspected part to move to the first loading position, the second loading platform 13 is always located below the inspected part, which effectively avoids the second loading platform 13 applying frictional resistance to the inspected part, thereby causing scratches on the inspected part or causing deflection of the inspected part, thereby ensuring the smooth and smooth transmission of the inspected part.

[0172] In some embodiments, Fig.11 and Fig.12 As shown, when the first loading platform 12 is located at the first loading position and the second loading platform 13 is located at the second loading position, the first loading platform 12 and the second loading platform 13 are plugged into each other, which includes the following schemes: 1. At least part of the first loading platform 12 is plugged into the second loading platform 13, and the part of the first loading platform 12 plugged into the second loading platform 13 can be used to carry the parts to be tested; 2. At least part of the second loading platform 13 is plugged into the first loading platform 12, and the second loading platform 13 is plugged into Part of the first loading platform 12 can be used to receive the parts to be detected transferred from the first loading platform 12; 3. At least part of the first loading platform 12 is plugged into the second loading platform 13, and at least part of the second loading platform 13 is plugged into the first loading platform 12. The part of the first loading platform 12 plugged into the second loading platform 13 can be used to carry the parts to be detected, and the part of the second loading platform 13 plugged into the first loading platform 12 can be used to receive the parts to be detected transferred from the first loading platform 12. Thus, in the first loading position, it is convenient to ensure that the parts to be detected are stably and smoothly transferred from the first loading platform 12 to the second loading platform 13 when the second loading platform 13 and the first loading platform 12 move relative to each other in the first direction.

[0173] In addition, since the first loading platform 12 is plugged into the second loading platform 13 at the first loading position, the second loading platform 13 and the first loading platform 12 are close to each other in the first direction, which makes it convenient to arrange the driving device for driving the first loading platform 12 to move on the side of the first loading platform 12 away from the conveying component 20, and the driving device will not block or interfere with the movement of the second loading platform 13, which is beneficial to the reasonable layout of the loading component 1 and the conveying component 4; at the same time, compared with the second loading platform being located on the side of the first loading platform facing away from the conveying component at the first loading position, the present application arranges the first loading platform 12 to be plugged into the second loading platform 13 at the first loading position, which can appropriately reduce the distance between the second loading platform 13 and the conveying component 4 in the second direction, reduce the moving distance of the second loading platform 13, and is beneficial to further improve the loading efficiency.

[0174] In some embodiments, Fig.11 and Fig.12 As shown, the first loading platform 12 includes a plurality of first support ribs 121 spaced apart along the second direction, and each first support rib 121 can extend along the first direction. The second loading platform 13 includes a plurality of second support ribs 131 spaced apart along the second direction, and each second support rib 131 can extend along the first direction. When the first loading platform 12 is located at the first loading position and the second loading platform 13 is located at the second loading position, the plurality of first support ribs 121 and the plurality of second support ribs 131 are staggered along the third direction. At this time, one or more second support ribs 131 can be inserted between at least two adjacent first support ribs 121, and / or one or more first support ribs 121 can be inserted between at least two adjacent second support ribs 131, thereby further ensuring that the parts to be inspected are smoothly transferred from the first loading platform 12 to the second loading platform 13, and the first loading platform 12 will not interfere with the movement of the second loading platform 13.

[0175] It can be understood that the plurality of first support ribs 121 can be arranged at uniform intervals or at non-uniform intervals along the third direction; the plurality of second support ribs 131 can be arranged at uniform intervals or at non-uniform intervals along the third direction.

[0176] In addition, by configuring the first loading platform 12 to support the workpiece to be inspected by a plurality of first supporting ribs 121, the contact area between the first loading platform 12 and the workpiece to be inspected can be reduced, thereby reducing the risk of the first loading platform 12 scratching the workpiece to be inspected; configuring the second loading platform 13 to support the workpiece to be inspected by a plurality of second supporting ribs 131 can reduce the contact area between the second loading platform 13 and the workpiece to be inspected, thereby reducing the risk of the second loading platform 13 scratching the workpiece to be inspected.

[0177] Optionally, at the first loading position, multiple first support ribs 121 and multiple second support ribs 131 are staggered one by one along the third direction. Then, at the first loading position, a second support rib 131 is provided between two adjacent first support ribs 121, and a first support rib 121 is provided between two adjacent second support ribs 131. Therefore, when the parts to be inspected are jointly supported by the multiple first support ribs 121 on the first loading platform 12, it is convenient to ensure that the parts to be inspected are also jointly supported by the multiple second support ribs 131 when they are transferred to the second loading platform 13, thereby not only ensuring the stable transfer of the parts to be inspected, but also ensuring the placement stability of the parts to be inspected on the second loading platform 13 and the first loading platform 12.

[0178] In some embodiments of the present invention, Fig.13 , Fig.14 and Fig.36 As shown, the conveying component 4 is formed with a detection port 4a, there are multiple camera components 2, and the multiple camera components 2 include a first camera component 2A and a second camera component 2B, the first camera component 2A and the second camera component 2B are respectively arranged on the opposite sides of the conveying component 4, and the second camera component 2B is arranged opposite to the detection port 4a, then the first camera component 2A can collect the image information of the surface of the side of the inspected part away from the conveying component 4, and the second camera component 2B can collect the image information of the surface of the inspected part that contacts the conveying component 4 through the detection port 4a, without turning the inspected part over for another collection, which is beneficial to improving the inspection efficiency of the appearance inspection equipment 100.

[0179] For example, in Fig.13 and Fig.14 In the example, the first camera component 2A is arranged on the upper side of the transmission component 4 and is used to collect image information of the upper surface of the part to be detected, and the second camera component 2B is arranged on the lower side of the transmission component 4 and is used to collect image information of the lower surface of the part to be detected.

[0180] In some embodiments, Fig.36 As shown, the conveying assembly 4 includes a frame 41 and a conveying mechanism 42, the conveying mechanism 42 is arranged on the frame 41, there are multiple conveying mechanisms 42, and the multiple conveying mechanisms 42 include a first conveying mechanism 42a, a second conveying mechanism 42b and a third conveying mechanism 42c arranged in sequence along a first direction, and the part to be detected passes through the first conveying mechanism 42a, the second conveying mechanism 42b and the third conveying mechanism 42c in sequence. Among them, the second conveying mechanism 42b and the third conveying mechanism 42c are spaced to define a detection port 4a.

[0181] In some embodiments of the present invention, Figure 37-Figure 39As shown, at least one conveying mechanism 42 includes a first driving wheel 421, a first driven wheel 422 and a first conveying belt 423 sleeved outside the first driving wheel 421 and the first driven wheel 422. The first conveying belt 423 has a conveying portion 4231 for carrying the part to be detected.

[0182] For example, in Figure 37-Figure 39 In the example, the first conveyor belt 423 is arranged horizontally, and the first conveyor belt 423 is tensioned on the first driving wheel 421 and the first driven wheel 422. The first driving wheel 421 drives the first conveyor belt 423 to move, so as to drive the first driven wheel 422 to rotate, thereby realizing the transmission of the first conveyor belt 423; wherein, the upper side of the first conveyor belt 423 has a transmission part 4231, and the part to be detected can be placed on the transmission part 4231. When the transmission belt is running, the transmission part 4231 runs along the transmission direction to realize the transmission of the part to be detected, and after completing the transmission of the part to be detected, it rotates again from the lower side of the first driving wheel 421 and the first driven wheel 422 to the upper side of the first driving wheel 421 and the first driven wheel 422. Then, during the operation of the first conveyor belt 423, the part of the first conveyor belt 423 located on the upper side of the first driving wheel 421 and the first driven wheel 422 can be used as the transmission part 4231 to carry the part to be detected. Of course, the first conveyor belt 423 can also be arranged to be inclined relative to the horizontal plane or arranged vertically.

[0183] like Figure 37-Figure 39 As shown, the conveying assembly 4 also includes a support plate 43, which is arranged on the frame 41, and the support plate 43 is supported on the bottom of the conveying part 4231, then the support plate 43 can indirectly support the part to be detected through the conveying part 4231, reduce the force borne by the conveying part 4231, thereby reducing the deformation of the conveying part 4231 caused by carrying the part to be detected, and then ensure the flatness of the part to be detected placed on the conveying part 4231, and avoid the part to be detected from tilting due to large deformation of the conveying part 4231, etc., which affects the detection accuracy of the detection equipment.

[0184] It is understandable that the support plate 43 will not move with the operation of the transmission belt, so as to ensure that the support plate 43 is always supported at the bottom of the conveying part 4231 during the process of the conveying component 4 conveying the parts to be inspected, and regardless of whether the conveying part 4231 carries the parts to be inspected, the support plate 43 is also supported at the bottom of the conveying part 4231.

[0185] In some embodiments of the present invention, Figure 36-Figure 39As shown, at least one of the first conveyor belts 423 of the conveyor mechanism 42 is provided with a support plate 43, and the number of the conveyor mechanisms 42 provided with the support plates 43 is less than or equal to the total number of the conveyor mechanisms 42. Thus, it is convenient to realize the flexible setting of the support plates 43, which is conducive to realizing the diversified structural design of the conveyor assembly 4.

[0186] For example, there are two conveying mechanisms 42, and the first conveyor belt 423 of each conveying mechanism 42 is respectively provided with a support plate 43, or the first conveyor belt 423 of one of the conveying mechanisms 42 is correspondingly provided with a support plate 43. At this time, the conveying mechanism 42 provided with the support plate 43 can be set corresponding to the camera component 2 of the detection equipment to ensure that the part to be detected is placed flat when the part to be detected is conveyed to the position corresponding to the camera component 2, but it is not limited to this.

[0187] It can be understood that one conveying mechanism 42 may be provided with one or more supporting plates 43 .

[0188] Of course, there may be three or more transmission mechanisms 42. Fig.36 , Fig.40 and Fig.41 In the example, there are three conveying mechanisms 42 , two of which are respectively provided with support plates 43 , one of which is provided with one support plate 43 , and the other is provided with two support plates 43 .

[0189] In some embodiments of the present invention, Figure 37-Figure 39 As shown, the first conveyor belt 423 is roughly formed as an annular structure, the support plate 43 is arranged on the inner side of the first conveyor belt 423, and the support plate 43 is located between the first driving wheel 421 and the first driven wheel 422. This can help reduce the volume of the support plate 43 and the amount of material used for the support plate 43 while ensuring that the support plate 43 can reliably support the conveying part 4231, thereby facilitating the arrangement of the support plate 43 and reducing costs.

[0190] Of course, in other embodiments of the present application, a portion of the support plate 43 may be disposed on the inner side of the first conveyor belt 423 and between the first driving wheel 421 and the first driven wheel 422 , and another portion of the support plate 43 may be disposed on the outer side of the conveyor belt.

[0191] For example, a first camera component 2A is provided on the upper side of the conveying component 4, and a second camera component 2B is provided on the lower side of the conveying component 4. The part to be inspected is placed horizontally on the conveying component 4, and the first camera component 2A shoots downward to collect image information of the upper surface of the part to be inspected, and the second camera component 2B shoots upward to collect image information of the lower surface of the part to be inspected through the inspection port 4a, so that the inspection equipment can realize image collection of the upper and lower surfaces of the part to be inspected during one transmission process of the part to be inspected, thereby improving the inspection efficiency.

[0192] The two adjacent conveying mechanisms 42 defining the inspection port 4a are configured to convey synchronously, so as to ensure that the inspected object passes the inspection position relative to the inspection port 4a smoothly and at a uniform speed, and to ensure that the camera assembly 2 accurately collects image information. The two conveying mechanisms 42 convey synchronously, which can be understood as the first conveyor belts 423 of the two conveying mechanisms 42 having the same conveying speed.

[0193] In some embodiments, Fig.36 and Fig.40 As shown, the transmission assembly 4 also includes a third driving mechanism 45, which is used to drive the first driving wheel 421 to rotate, thereby realizing the operation of the transmission mechanism 42, wherein the first driving wheels 421 of two adjacent transmission mechanisms 42 that define the detection port 4a are arranged adjacent to each other, and the above-mentioned two first driving wheels 421 are suitable for being driven to rotate by the same third driving mechanism 45, so as to effectively ensure the synchronous transmission of the above-mentioned two transmission mechanisms 42.

[0194] For example, in Fig.45 and Fig.46 In the example, the third driving mechanism 45 may include a motor 451 and a gear transmission mechanism 452, the gear transmission mechanism 452 includes a driving gear and two driven gears, the driving gear drives the two driven gears to rotate at the same time, and the gear transmission mechanism 452 may be arranged in a gear box.

[0195] Of course, the first driving wheels 421 of the two adjacent conveying mechanisms 42 that define the detection port 4a can also be respectively connected to different third driving mechanisms 45 so as to be driven to rotate by different third driving mechanisms 45, which can also realize the synchronous transmission of the above-mentioned two conveying mechanisms 42 and is conducive to reducing costs.

[0196] In some embodiments of the present invention, Fig.41 and Fig.42As shown, the support plate 43 is movably connected to the frame 41, and a leveling mechanism 44 is provided on the side of the support plate 43 facing away from the conveying portion 4231. The leveling mechanism 44 is used to adjust the inclination of the support surface of the support plate 43 relative to the conveying plane. The leveling mechanism 44 can adjust the angle between the support surface and the conveying plane so that the support surface is set close to the conveying plane, so as to effectively ensure the flatness of the support surface, thereby further improving the flatness of the placement of the parts to be inspected.

[0197] It should be noted that the "transmission plane" can be understood as the placement plane of the part to be detected under an ideal state. If the support plate 43 is not provided, the transmission part 4231 may be deformed under the gravity of the part to be detected, so that the bearing surface of the transmission part 4231 deviates from the transmission plane. By providing the support plate 43 and setting the leveling mechanism 44 to adjust the inclination of the support surface relative to the transmission plane, the transmission part can be supported by the support plate 43, and the bearing surface also tends to the transmission plane, thereby improving the flatness of the placement of the part to be detected. For example, if the part to be detected is placed horizontally during the transmission process, the transmission plane can be a horizontal plane.

[0198] In some embodiments of the present invention, Fig.41 and Fig.42 As shown, the support plate 43 has a plurality of adjustment portions 431 spaced apart along the outer periphery of the support plate 43, and the leveling mechanism 44 includes a plurality of adjustment members 441 and a plurality of guide members 442, each adjustment member 441 is disposed through the corresponding adjustment portion 431, and each adjustment member 441 is used to adjust the height of the adjustment portion 431 relative to the frame 41, then the leveling mechanism 44 can adjust the height of a plurality of positions on the support plate 43 relative to the frame 41, thereby realizing the adjustment of the inclination of the support surface relative to the conveying plane, each guide member 442 is disposed through In the corresponding adjustment part 431, each guide member 442 is used to guide the movement of the adjustment part 431 relative to the frame 41. That is to say, in the process of the adjustment member 441 adjusting the height of the adjustment part 431 relative to the frame 41, the adjustment part 431 moves relative to the frame 41, and the guide member 442 can guide the movement of the adjustment part 431 to avoid the position deviation of the adjustment part 431, so as to ensure the adjustment accuracy of the leveling mechanism 44, and at the same time ensure that the adjustment member 441 is always coordinated with the adjustment part 431 and the frame 41.

[0199] For example, the support plate 43 is formed as a square plate, and at least four corners of the support plate 43 are respectively formed as adjustment portions 431, that is, there are at least four adjustment portions 431. Fig.41 and Fig.42In the example, the support plate 43 has four adjustment parts 431, and the four adjustment parts 431 are respectively located at the four corners of the support plate 43. At this time, there can be four adjustment members 441, and each adjustment member 441 is used to adjust the height of the corner of the support plate 43 relative to the frame 41, which is beneficial to improve the adjustment efficiency of the leveling mechanism 44.

[0200] Of course, the shape of the support plate 43 and the number of the adjustment parts 431 are not limited thereto; for example, the support plate 43 is formed as a square plate, and the number of the adjustment parts 431 can also be six, seven, or eight.

[0201] In some embodiments, Fig.41 and Fig.42 As shown, the adjusting member 441 is penetrated through the adjusting portion 431, and the adjusting member 441 is threadedly matched with the adjusting portion 431, and one end of the length of the adjusting member 441 stops at the frame 41, then rotating the adjusting member 441 can make the adjusting member 441 and the adjusting portion 431 move relative to each other in the length direction of the adjusting member 441, so that the relative position of the adjusting portion 431 and the frame 41 in the length direction of the adjusting member 441 can be adjusted to achieve height adjustment of the adjusting portion 431 relative to the frame 41, and because the adjusting member 441 is threadedly matched with the adjusting portion 431, the stepless adjustment of the adjusting mechanism can be achieved to ensure the adjustment flexibility of the leveling mechanism 44 and ensure that the supporting surface effectively tends to the conveying plane setting.

[0202] The guide member 442 is fixed to the frame 41, and the guide member 442 and the adjusting part 431 are slidably matched. Therefore, during the process of the adjusting member 441 adjusting the relative position of the adjusting part 431 and the frame 41, the adjusting part 431 can slide along the guide member 442 to ensure that the projection position of the adjusting part 431 along the moving direction remains unchanged, thereby preventing the adjusting part 431 from moving in other directions and causing the adjusting member 441 to be disengaged from the stopper on the frame 41, thereby facilitating improving the reliability of the leveling mechanism 44.

[0203] For example, in Fig.42 In the example, the adjusting portion 431 may be formed with an adjusting hole 431a and a guide hole 431b, the adjusting member 441 is threadedly engaged with the adjusting hole 431a, the guide member 442 is passed through the guide hole 431b and the guide member 442 and the guide hole 431b slide upward and downward, and the lower end of the guide member 442 is mounted on the mounting hole 41a on the frame 41. The frame 41 may include a frame body 411 and a support block 412, the support block 412 is fixed on the frame body 411, and the support block 412 extends into the lower side of the support plate 43, the lower end of the adjusting member 441 stops at the support block 412, and the guide member 442 is mounted on the support block 412.

[0204] In some embodiments of the present invention, Fig.43 and Fig.44As shown, the end of the first driving wheel 421 away from the third driving mechanism 45 is penetrated through the frame 41, and the above-mentioned end of the first driving wheel 421 is rotatably connected to the bearing seat 47 through the support bearing 46, the bearing seat 47 is detachably connected to the frame 41, and the bearing seat 47 is formed with a disassembly hole 47a, and the disassembly hole 47a is arranged opposite to the end surface of the above-mentioned end of the first driving wheel 421. Therefore, when it is necessary to disassemble the cooperation between the first driving wheel 421 and the support bearing 46, the bearing seat 47 can be disassembled from the frame 41 first, and then the disassembly member can be extended into the disassembly hole 47a, and the disassembly member can be stopped against the end surface of the end of the first driving wheel 421 away from the third driving mechanism 45, at this time, a force is applied to the disassembly member toward the first driving wheel 421, and / or a force is applied to the bearing seat 47 away from the first driving wheel 421, so as to realize the rapid separation of the first driving wheel 421 and the support bearing 46, thereby improving the disassembly efficiency.

[0205] Optionally, the disassembly member may be a threaded member such as a screw, in which case the disassembly member may be threadedly matched with the disassembly hole 47a, and after the disassembly member stops at the first driving wheel 421, the disassembly member may be rotated to achieve rapid separation of the first driving wheel 421 and the bearing seat 47. Of course, the disassembly member may also be a non-threaded member, in which case the disassembly member may be struck in a direction toward the first driving wheel 421, and the first driving wheel 421 and the bearing seat 47 may also be rapidly separated.

[0206] It is understandable that when there are multiple transmission mechanisms 42, at least one of the multiple first driving wheels 421 is correspondingly provided with a bearing seat 47 with a disassembly hole 47a. When two first driving wheels 421 are arranged adjacent to each other, the two first driving wheels 421 can share the same bearing seat 47 with a disassembly hole 47a.

[0207] For example, in Fig.43 and Fig.44 In the example, the detection port 4a is defined between the second conveying mechanism 42b and the third conveying mechanism 43c, and the first driving wheel 421 of the second conveying mechanism 42b and the first driving wheel 421 of the third conveying mechanism 43 are arranged adjacent to each other and share the same bearing seat 47 with a disassembly hole 47a. Of course, the detection port 4a may not be defined between the two conveying mechanisms 42 corresponding to the two first driving wheels 421 that share the same bearing seat 47 with a disassembly hole 47a.

[0208] In some embodiments of the present invention, Fig.13 and Fig.14As shown, the appearance inspection device 100 also includes a light source component 5, which is arranged between the first camera component 2A and the transmission component 4, and the light source component 5 is used to provide a light source for the first camera component 2A, so as to provide sufficient brightness for the part to be inspected, so that the image information collected by the first camera component 2A is clearer and has good recognition, so as to ensure the detection accuracy of the detection equipment.

[0209] In some embodiments, Fig.28 and Fig.33 As shown, the light source assembly 5 includes a box body 51, and the box body 51 defines a light channel 510, and the light channel 510 is for light to pass through. One end of the light channel 510 is formed as a collection port 510a, and the camera assembly 2 is arranged at the collection port 510a, so that the part to be detected can smoothly reflect the light of the light source assembly 5 toward the camera assembly 2, and the other end of the light channel 510 is formed as a light outlet 510b, and the light of the light source assembly 5 can be emitted through the light outlet 510b to irradiate the part to be detected.

[0210] The light source assembly 5 also includes a first light source component 52 and a first scattering component 53. The first light source component 52 is arranged in the box body 51, and the first light source component 52 can be used to provide bypass illumination light. The first scattering component 53 is arranged in the box body 51, and the first scattering component 53 is used to diffusely reflect the light emitted by the first light source component 52 and emit it toward the light outlet 510b.

[0211] The light source assembly 5 also includes a second light source component 54 and a reflective component 55. The second light source component 54 can be used to provide projected illumination light. The second light source component 54 is arranged in the housing 51, and the second light source component 54 is located on the side of the first light source component 52 adjacent to the collection port 510a. That is to say, corresponding to the first light source component 52 and the second light source component 54, the distance between the first light source component 52 and the collection port 510a is greater than the distance between the second light source component 54 and the collection port 510a; the reflective component 55 is arranged in the housing 51, and the reflective component 55 blocks the light channel 510. The reflective component 55 has a certain ability to reflect and transmit light. The reflective component 55 is used to reflect the light emitted by the first light source component 52 toward the light outlet 510b. At the same time, the reflective component 55 will not block the light reflected by the part to be detected, thereby ensuring that the light reflected by the part to be detected can smoothly pass through the reflective component 55 to be collected by the camera assembly 2 arranged at the collection port 510a.

[0212] For example, in Fig.33In the example, the part to be detected can be placed horizontally during the detection process, the light source assembly 5 can illuminate the part to be detected downward, the light channel 510 can be vertically arranged, the upper end of the light channel 510 is formed as a collection port 510a, and the lower end of the light channel 510 is formed as a light outlet 510b; the first light source component 52 and the second light source component 54 are arranged at intervals up and down, and the first light source component 52 is arranged below the second light source component 54 (including directly below and obliquely below), the first scattering component 53 is arranged corresponding to the first light source component 52, and the reflective component 55 is arranged corresponding to the second light source component 54, so that the first scattering component 53 is arranged at intervals below the reflective component 55.

[0213] For the part to be detected with a mirror component, vertical projection light irradiation is required. At this time, the second light source component 54 and the anti-transmission component 55 can be used together to enable the light source assembly 5 to provide mirror reflection light, so that the camera assembly 2 can capture high-definition and high-recognition images; for the part to be detected with a non-mirror component, uniform side light irradiation is required. At this time, the first light source component 52 and the first scattering component 53 can be used together to enable the light source assembly 5 to provide diffuse reflection light, so that the camera assembly 2 can obtain high-definition and high-recognition images. Of course, if vertical projection light and uniform side light are required at the same time, the light source assembly 5 can provide appropriate light irradiation through the cooperation of the first light source component 52 and the first scattering component 53, the cooperation of the second light source component 54 and the anti-transmission component 55, and the cooperation of the above two groups of light source components.

[0214] like Fig.33 As shown, the light source assembly 5 also includes a light absorbing member 56, which is arranged on the side of the reflective member 55 away from the second light source member 54. Then, part of the light from the second light source member 54 passes through the reflective member 55 and shines on the light absorbing member 56. There is no transmission other than illumination, and no mapping, large flares and reflections are generated. Instead, after the light is absorbed by the light absorbing member 56, part of the light is diffusely reflected, thereby maintaining regular light and dark levels. That is, the light absorbing member 56 can absorb the light of the second light source member 54 that passes through the reflective member 55. This part of the light is difficult to control. The light absorbing member 56 absorbs this part of the light, which can prevent this part of the light from being diffusely reflected by the box body 51 and other components and then irradiated toward the camera assembly 2 and the part to be detected, thereby affecting the image effect captured by the camera assembly 2.

[0215] Optionally, the reflective component 55 may include a glass piece, and the glass piece has a certain light reflection ability and light transmission ability, so that the reflective component 55 can reflect the light of the second light source component 54, and the light reflected by the component to be detected can pass through the reflective component 55 and be emitted to the camera assembly 2.

[0216] In some embodiments, Fig.28 , Fig.30 , Fig.32 and Fig.33 As shown, the outer surface of the box body 51 is provided with a plurality of heat dissipation ribs 511 , and the heat dissipation ribs 511 can be provided on the back side of the first light source component 52 and / or the second light source component 54 , which is beneficial to ensure the heat dissipation performance of the light source assembly 5 and ensure the reliable use of the light source assembly 5 .

[0217] Of course, a heat dissipation fan may also be provided on the box body 51 to improve the heat dissipation performance of the light source assembly 5 .

[0218] In some embodiments of the present invention, Fig.33 As shown, there are two first light source components 52 and two first scattering components 53, that is, there are two first light source components 52 and two first scattering components 53, the two first scattering components 53 are arranged at intervals, and the two first scattering components 53 are both arranged at the light outlet 510b, and each first light source component 52 is arranged on the side of the corresponding first scattering component 53 away from the other first scattering component 53. Therefore, it is beneficial to further improve the light uniformity of the light source provided by the first light source component 52 of the light source assembly 5.

[0219] For example, in Fig.33 In the example, the two first scattering components 53 are arranged at intervals in the left-right direction, the left-side first scattering component 53 is arranged corresponding to the left-side first light source component 52, the right-side first scattering component 53 is arranged corresponding to the right-side first light source component 52, and the left-side first light source component 52 is arranged on the left side of the left-side first scattering component 53, and the right-side first light source component 52 is arranged on the right side of the right-side first scattering component 53.

[0220] Of course, there may be one, three or more first light source components 52 , and there may be one, three or more first scattering components 53 ; wherein the number of first light source components 52 and the number of first scattering components 53 may be equal or different.

[0221] In some embodiments of the present invention, Fig.33 As shown, the two first scattering components 53 are symmetrically arranged about the light outlet 510b, and the two first light source components 52 are symmetrically arranged about the light outlet 510b, so that the light output of the first light source components 52 and the first scattering components 53 is more uniform after cooperation, which is beneficial to improving the light output uniformity of the light source assembly 5.

[0222] Of course, the two first scattering components 53 may also be arranged asymmetrically with respect to the light outlet 510 b , and the two first light source components 52 may also be arranged asymmetrically with respect to the light outlet 510 b .

[0223] In some embodiments of the present invention, Fig.33As shown, the housing 51 is formed with a mounting groove 51a, and the mounting groove 51a is concave in a direction away from the corresponding first scattering component 53. The first light source component 52 is mounted in the mounting groove 51a, and the first light source component 52 includes a first light source component 521 and a second light source component 522. The light of the first light source component 521 and the light of the second light source component 522 are respectively diffusely reflected by the first scattering component 53, so as to effectively ensure that the first light source component 52 provides relatively uniform light output. Among them, the angle α between the first light source component 521 and the second light source component 522 satisfies 135°≤α<180°, so as to ensure the uniformity of light output of the first light source component 521 and the second light source component 522.

[0224] For example, in Fig.33 In the example, there are two first light source components 52 and two first scattering components 53, and two mounting grooves 51a, each of which is used to mount a corresponding first light source component 52, and each first light source component 52 includes a first light source element 521 and a second light source element 522. The angle between the first light source element 521 and the second light source element 522 of one first light source component 52 can be equal to or different from the angle between the first light source element 521 and the second light source element 522 of another first light source component 52.

[0225] Optionally, the first light source component 52 is bonded to the wall surface of the installation groove 51a, so as to ensure reliable installation of the first light source component 52. Of course, the installation method of the first light source component 52 is not limited thereto.

[0226] In some embodiments of the present invention, Fig.28 , Fig.30 and Fig.32 As shown, the box body 51 is formed with two first matching grooves 51b, and the two first matching grooves 51b can be arranged along the length direction of the first scattering component 53 (for example, Fig.28 The first scattering component 53 is arranged at intervals in the front-to-back direction, and the two ends of the length of the first scattering component 53 are respectively pulled and matched with the corresponding first matching grooves 51b, that is, one end of the length of the first scattering component 53 is matched with one of the first matching grooves 51b and is pulled and matched with the first matching groove 51b, and the other end of the length of the first scattering component 53 is matched with another first matching groove 51b and is pulled and matched with the first matching groove 51b, thereby facilitating the disassembly and assembly of the first scattering component 53.

[0227] Optionally, the first scattering component 53 and the first matching groove 51b are pulled together along the length direction of the first scattering component 53. At this time, at least one first matching groove 51b can penetrate the box body 51 along the length direction of the first scattering component 53 to facilitate the first scattering component 53 to be inserted into the two first matching grooves 51b.

[0228] Of course, the present application is not limited to this; for example, the first scattering component 53 and the first matching groove 51b are pulled and matched along the width direction of the first scattering component 53. At this time, each first matching groove 51b can pass through the box body 51 along the width direction of the first scattering component 53, so that the two ends of the length of the first scattering component 53 can be respectively inserted into the corresponding first matching groove 51b; wherein the width direction of the first scattering component 53 can be perpendicular to the length direction of the first scattering component 53.

[0229] In some embodiments of the present invention, Fig.33 As shown, the light source assembly 5 also includes a second scattering component 57, which is arranged between the second light source component 54 and the reflective component 55, and the second scattering component 57 is used to scatter the light emitted by the second light source component 54 to the reflective component 55, so that the second scattering component 57 can increase the projection range and uniformity of the light emitted by the second light source component 54.

[0230] In some embodiments of the present invention, Fig.28 and Fig.33 As shown, the box body 51 is formed with two second matching grooves 51c, and the two second matching grooves 51c can be arranged along the length direction of the anti-transmission component 55 (for example, Fig.28 The two ends of the length of the anti-transmission component 55 are respectively matched with the corresponding second matching grooves 51c for pulling and matching, that is, one end of the length of the anti-transmission component 55 is matched with one of the second matching grooves 51c and is pulled and matched with the second matching groove 51c, and the other end of the length of the anti-transmission component 55 is matched with the other second matching groove 51c and is pulled and matched with the second matching groove 51c, thereby facilitating the disassembly and assembly of the anti-transmission component 55.

[0231] Alternatively, if Fig.28 , Fig.30 and Fig.33 As shown, in the width direction of the anti-transparent component 55, one end of each second matching groove 51c passes through the box body 51 to form a plug-in port 51d, and the anti-transparent component 55 passes through the plug-in port 51d, and the anti-transparent component 55 and the second matching groove 51c are pulled and matched along the width direction of the anti-transparent component 55, so that the two ends of the length of the anti-transparent component 55 are respectively plugged into the corresponding second matching groove 51c; wherein, the width direction of the anti-transparent component 55 can be perpendicular to the length direction of the anti-transparent component 55.

[0232] Of course, the present application is not limited to this; for example, the anti-transmission component 55 and the second matching groove 51c are pulled together along the length direction of the anti-transmission component 55. At this time, at least one second matching groove 51c can penetrate the box body 51 along the length direction of the anti-transmission component 55, so that the anti-transmission component 55 can be inserted into the two second matching grooves 51c.

[0233] In some embodiments of the present invention, Fig.29, Fig.31 and Fig.33 As shown, the light source assembly 5 further includes a stopper 58, which is disposed at at least one of the two mating ports 51d, and a stopper 58 is disposed at one of the two mating ports 51d, or a stopper 58 is disposed at each mating port 51d, wherein the stopper 58 is movably connected to the housing 51, and the stopper 58 can move relative to the housing 51 between the avoidance position and the stopper position, in the stopper position, the stopper 58 blocks at least part of the mating port 51d to limit the anti-transmission component 55 from separating from the second mating groove 51c from the mating port 51d, and in the avoidance position, the stopper 58 avoids the mating port 51d, and at this time, the anti-transmission component 55 can be detached from the second mating groove 51c from the mating port 51d, or installed in the second mating groove 51c from the mating port 51d. Therefore, by providing the stopper 58, it is ensured that the anti-transmission component 55 is reliably matched with the second mating groove 51c, and at the same time, the disassembly and assembly of the anti-transmission component 55 will not be affected.

[0234] It can be understood that the movable connection mode between the stopper 58 and the box body 51 can be set according to actual needs; for example, the stopper 58 is detachably connected to the box body 51, and in the stop position, the stopper 58 is installed on the box body 51, and in the avoidance position, the stopper 58 is detached from the box body 51; for another example, the stopper 58 is always connected to the box body 51, and the stopper 58 is movable or rotatable relative to the box body 51.

[0235] Furthermore, in the stopping position, the stopper 58 may only block a portion of the mating opening 51 d or may completely block the mating opening 51 d .

[0236] In some embodiments of the present invention, Fig.13 and Fig.14 As shown, the appearance inspection device 100 also includes a cleaning component 3, which can be used to clean the parts to be inspected, so as to ensure the inspection accuracy of the appearance inspection device 100; the cleaning component 3 is arranged on the conveying component 4, and in the conveying direction, the cleaning component 3 is arranged on the upstream side of the camera component 2 to clean the parts to be inspected before image acquisition of the parts to be inspected.

[0237] For example, in Fig.36 In the example, the conveying component 4 includes a plurality of conveying mechanisms 42, and the plurality of conveying mechanisms 42 include a first conveying mechanism 42a, a second conveying mechanism 42b and a third conveying mechanism 42c arranged in sequence along the conveying direction. The cleaning component 3 is disposed between the first conveying mechanism 42a and the second conveying mechanism 42b to connect the first conveying mechanism 42a and the second conveying mechanism 42b. The cleaning component 3 can clean the inspected part during the process of being conveyed from the first conveying mechanism 42a to the second conveying mechanism 42b.

[0238] In some embodiments of the present invention, Fig.15 As shown, the cleaning assembly 3 includes a mounting frame 31, a first cleaning roller 32 and a second cleaning roller 33, the first cleaning roller 32 is rotatably arranged on the mounting frame 31, the second cleaning roller 33 is rotatably arranged on the mounting frame 31, and the second cleaning roller 33 can move relative to the mounting frame 31 between the matching position and the separation position, in the matching position, the second cleaning roller 33 and the first cleaning roller 32 are rollingly matched, in the separation position, the second cleaning roller 33 and the first cleaning roller 32 are spaced apart, and at this time, the part to be detected can pass through the gap between the first cleaning roller 32 and the second cleaning roller 33 to be transmitted from the first conveying mechanism 42a to the second conveying mechanism 42b, so that the first cleaning roller 32 and the second cleaning roller 33 can clean the opposite sides of the part to be detected. Wherein, the central axis 32a of the first cleaning roller 32 can be perpendicular to the conveying direction.

[0239] The cleaning assembly 3 also includes a first driving mechanism 35, which is arranged on the mounting frame 31, and the first driving mechanism 35 is connected to the first cleaning roller 32 to drive the first cleaning roller 32 to rotate. When the second cleaning roller 33 is in the matching position, the first cleaning roller 32 can drive the second cleaning roller 33 to rotate, at which time, the dust and other dirt on the first cleaning roller 32 can be taken away by the second cleaning roller 33, and / or, the dust and other dirt on the second cleaning roller 33 can be taken away by the first cleaning roller 32; when the second cleaning roller 33 is in the separation position, the gap between the first cleaning roller 32 and the second cleaning roller 33 is convenient for the detection part to pass through, so as to achieve the cleaning of the detection part. Among them, the first driving mechanism 35 can be directly or indirectly arranged on the mounting frame 31.

[0240] like Fig.15 As shown, the cleaning component 3 also includes a sticky roller 34, which is rotatably disposed on the mounting frame 31, and the sticky roller 34 is used to directly clean the first cleaning roller 32 and / or the second cleaning roller 33, and includes the following schemes: 1. For the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 is only used to directly clean the first cleaning roller 32; 2. For the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 is only used to directly clean the second cleaning roller 33; 3. The sticky roller 34 directly cleans the first cleaning roller 32, and the sticky roller 34 directly cleans the second cleaning roller 33, and at this time, there can be multiple sticky rollers 34.

[0241] For example, when the sticky roller 34 is only used to directly clean the first cleaning roller 32 for the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 can directly take away the dust and other dirt on the first cleaning roller 32. When the second cleaning roller 33 is in the matching position, the dust and other dirt on the second cleaning roller 33 can be taken away by the first cleaning roller 32. Then, the sticky roller 34 can indirectly take away the dust and other dirt on the second cleaning roller 33 through the first cleaning roller 32 to clean the second cleaning roller 33. Thus, the sticky roller 34 can clean the first cleaning roller 32 and the second cleaning roller 33, so that the cleaning component 3 can be self-cleaned, ensuring the cleaning effect of the cleaning component 3 on the inspected part, and at the same time, the cleaning and maintenance frequency of the cleaning component 3 can be reduced, the service life of the cleaning component 3 can be extended, and the detection efficiency of the detection equipment can be prevented from being low due to frequent cleaning or maintenance of the cleaning component 3, which is conducive to improving the detection efficiency. Moreover, when cleaning and maintaining the cleaning component 3, only the sticky roller 34 can be cleaned or replaced according to the situation, which further facilitates the maintenance of the cleaning component 3.

[0242] For another example, when the sticky roller 34 is only used to directly clean the second cleaning roller 33 for the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 can directly take away the dust and other dirt on the second cleaning roller 33. When the second cleaning roller 33 is in the matching position, the dust and other dirt on the first cleaning roller 32 can be taken away by the second cleaning roller 33, and the sticky roller 34 can indirectly take away the dust and other dirt on the first cleaning roller 32 through the second cleaning roller 33 to clean the second cleaning roller 33. Therefore, the sticky roller 34 can also clean the first cleaning roller 32 and the second cleaning roller 33, so that the cleaning component 3 can achieve self-cleaning.

[0243] For another example, when the sticky roller 34 directly cleans the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 can directly take away the dust and other dirt on the first cleaning roller 32 and the dust and other dirt on the second cleaning roller 33, so as to clean the first cleaning roller 32 and the second cleaning roller 33, and also enable the cleaning component 3 to achieve self-cleaning.

[0244] Obviously, by setting up a sticky roller 34 to clean the first cleaning roller 32 and the second cleaning roller 33, the cleaning component 3 can achieve self-cleaning, ensuring the cleaning effect of the cleaning component 3 on the inspected part, and at the same time can reduce the cleaning and maintenance frequency of the cleaning component 3, extend the service life of the cleaning component 3, which is beneficial to improving the detection efficiency; moreover, by setting up the second cleaning roller 33 to be movable between the mating position and the separation position relative to the mounting frame 31, the dust on the first cleaning roller 32 and the dust on the second cleaning roller 33 can be transferred under the premise of ensuring that the inspected part passes through the cleaning component 3 smoothly, so that when the sticky roller 34 directly cleans the first cleaning roller 32, the sticky roller 34 can indirectly clean the second cleaning roller 33 through the first cleaning roller 32, and when the sticky roller 34 directly cleans the second cleaning roller 33, the sticky roller 34 can indirectly clean the first cleaning roller 32 through the second cleaning roller 33, which is beneficial to reduce the number of sticky rollers 34, simplify the structure of the cleaning component 3, and reduce costs.

[0245] In some embodiments of the present invention, Fig.15 As shown, the first cleaning roller 32 and the second cleaning roller 33 are both arranged horizontally, and the central axis 32a of the first cleaning roller 32 and the central axis 33a of the second cleaning roller 33 both extend horizontally or have a certain angle with the horizontal plane.

[0246] Among them, the second cleaning roller 33 slides and cooperates with the mounting frame 31 in the up-down direction, so that the second cleaning roller 33 can move up and down relative to the mounting frame 31 between the cooperation position and the separation position, and the second cleaning roller 33 is arranged on the upper side and / or the lower side of the first cleaning roller 32, which includes the following schemes: 1. The second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32 and slides and cooperates with the mounting frame 31 in the up-down direction; 2. The second cleaning roller 33 is arranged on the lower side of the first cleaning roller 32 and slides and cooperates with the mounting frame 31 in the up-down direction; 3. The second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32, and the second cleaning roller 33 is also arranged on the lower side of the first cleaning roller 32. At this time, there are multiple second cleaning rollers 33, and each second cleaning roller 33 slides and cooperates with the mounting frame 31 in the up-down direction. As a result, the second cleaning roller 33 has good layout flexibility, which is convenient for meeting actual differentiated needs.

[0247] When the second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32, if the sticky roller 34 is only used to directly clean the first cleaning roller 32, the sticky roller 34 can be arranged on the side of the first cleaning roller 32 away from the second cleaning roller 33, and the sticky roller 34 is arranged on the lower side of the first cleaning roller 32. At this time, the central axis 32a of the first cleaning roller 32, the central axis 33a of the second cleaning roller 33 and the central axis 34a of the sticky roller 34 can be in the same plane or not. If the sticky roller 34 is only used to directly clean the second cleaning roller 33 , the sticky roller 34 can be arranged on the side of the second cleaning roller 33 away from the first cleaning roller 32, and the sticky roller 34 is arranged on the upper side of the second cleaning roller 33. At this time, the central axis 32a of the first cleaning roller 32, the central axis 33a of the second cleaning roller 33 and the central axis 34a of the sticky roller 34 can be in the same plane or not in the same plane; of course, if the sticky roller 34 directly cleans the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 can be respectively provided on the lower side of the first cleaning roller 32 and the upper side of the second cleaning roller 33.

[0248] For example, in Fig.15 and Fig.17 In the example, the second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32, and the central axis 33a of the second cleaning roller 33 and the central axis 32a of the first cleaning roller 32 can be located in the same vertical plane. In the mating position, the bottom end of the second cleaning roller 33 rolls with the top end of the first cleaning roller 32, so that the part to be detected can pass through the cleaning assembly 3 roughly in the horizontal direction, which is conducive to reducing the positioning requirements of the part to be detected during the transmission process; and the sticky roller 34 is arranged on the upper side of the second cleaning roller 33, and the central axis 34a of the sticky roller 34, the central axis 33a of the second cleaning roller 33 and the central axis 32a of the first cleaning roller 32 are located in the same vertical plane. Of course, in other embodiments, the sticky roller 34 can also be located on the oblique upper side of the second cleaning roller 33; but it is not limited to this.

[0249] It can be understood that when the second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32, it is convenient to construct the second cleaning roller 33 so that the second cleaning roller 33 is always in the mating position at least under the action of its own gravity. At this time, when the part to be inspected passes through the cleaning component 3, the second cleaning roller 33 can be pushed toward the separation position to facilitate the part to be inspected to pass through the cleaning component 3 smoothly.

[0250] When the second cleaning roller 33 is arranged at the lower side of the first cleaning roller 32, if the sticky roller 34 is only used to directly clean the first cleaning roller 32, the sticky roller 34 can be arranged at the upper side of the first cleaning roller 32, at which time the central axis 32a of the first cleaning roller 32, the central axis 33a of the second cleaning roller 33 and the central axis 34a of the sticky roller 34 can be in the same plane or not; if the sticky roller 34 is only used to directly clean the second cleaning roller 33, the sticky roller 34 is arranged at the lower side of the second cleaning roller 33, at which time the central axis 32a of the first cleaning roller 32, the central axis 33a of the second cleaning roller 33 and the central axis 34a of the sticky roller 34 can be in the same plane or not; of course, if the sticky roller 34 directly cleans the first cleaning roller 32 and the second cleaning roller 33, the sticky roller 34 can be respectively arranged at the upper side of the first cleaning roller 32 and the lower side of the second cleaning roller 33.

[0251] It can be understood that when the second cleaning roller 33 is arranged on the lower side of the first cleaning roller 32, it is convenient to construct the second cleaning roller 33 so that the second cleaning roller 33 is always in the mating position at least under the action of other components (for example, the elastic return member described later). At this time, when the part to be inspected passes through the cleaning component 3, the second cleaning roller 33 can be pushed toward the separation position to facilitate the part to be inspected to pass through the cleaning component 3 smoothly.

[0252] When the second cleaning rollers 33 are respectively provided on the upper and lower sides of the first cleaning roller 32, if the sticky roller 34 is only used to directly clean the second cleaning roller 33, the upper side of the upper second cleaning roller 33 and the lower side of the lower second cleaning roller 33 may be respectively provided with sticky rollers 34; of course, the sticky roller 34 may also be only used to directly clean the first cleaning roller 32, but is not limited thereto.

[0253] It should be noted that, in the description of the present application, the first feature being “above”, “above” and “on the upper side” of the second feature means that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below” and “on the lower side” of the second feature means that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0254] It can be understood that when the first cleaning roller 32 and the second cleaning roller 33 are both formed into cylindrical structures, the outer diameter of the first cleaning roller 32 and the outer diameter of the second cleaning roller 33 may be equal or different.

[0255] In addition, the movement of the second cleaning roller 33 relative to the mounting frame 31 between the mating position and the separating position is not limited thereto; for example, the second cleaning roller 33 may also rotate relative to the mounting frame 31 between the mating position and the separating position.

[0256] In some embodiments of the present invention, Figure 15-17 As shown, the second cleaning roller 33 is configured so that the second cleaning roller 33 is often in the matching position, that is, the second cleaning roller 33 is often in the position of rolling matching with the first cleaning roller 32, that is, the second cleaning roller 33 has a tendency to be often in the matching position, for example, the second cleaning roller 33 can deviate from the matching position under the action of an external force, and when the external force is removed, the second cleaning roller 33 can move to the matching position by itself. Moreover, the second cleaning roller 33 is also configured so that when the part to be detected passes through the cleaning assembly 3, the part to be detected pushes the second cleaning roller 33 toward the separation position, so that the second cleaning roller 33 moves toward the separation position under the force applied by the part to be detected, so that the part to be detected can smoothly pass through the gap between the first cleaning roller 32 and the second cleaning roller 33, and when the part to be detected completely passes through the cleaning assembly 3, the second cleaning roller 33 can move to the matching position by itself.

[0257] Therefore, after each part to be inspected passes through the cleaning assembly 3, the dust sticking roller 34 can clean the first cleaning roller 32 and the second cleaning roller 33, so that the cleaning assembly 3 can perform self-cleaning once, so as to ensure the cleaning effect of the cleaning assembly 3 on the next part to be inspected.

[0258] In addition, since the second cleaning roller 33 is often in the mating position, the component to be detected needs to overcome a certain force to push the second cleaning roller 33 toward the separation position when passing through the cleaning component 3. At this time, the second cleaning roller 33 squeezes the component to be detected, so that the component to be detected is subjected to a certain squeezing force during the cleaning process between the first cleaning roller 32 and the second cleaning roller 33, so as to improve the cleaning effect of the component to be detected.

[0259] In some embodiments of the present invention, Figure 15-17 As shown, at least the upper side of the first cleaning roller 32 is provided with the second cleaning roller 33, then only the upper side of the first cleaning roller 32 is provided with the second cleaning roller 33, or the upper side and other sides of the first cleaning roller 32 (for example, the lower side of the first cleaning roller 32, etc.) are respectively provided with the second cleaning roller 33. Wherein, the second cleaning roller 33 arranged on the upper side of the first cleaning roller 32 is configured so that after the detected part passes through the cleaning assembly 3, the second cleaning roller 33 moves toward the matching position at least under the action of its own gravity, then after the detected part passes through the cleaning assembly 3, the detected part removes the force applied to the second cleaning roller 33, and the second cleaning roller 33 can move toward the matching position only under the action of its own gravity, or the second cleaning roller 33 can also move toward the matching position under the action of its own gravity and other components of the cleaning assembly 3 (for example, the dust sticking roller 34, the elastic reset member described later). Thus, it is convenient to simplify the movement setting of the second cleaning roller 33.

[0260] It can be understood that, since the second cleaning roller 33 moves toward the mating position at least under the action of its own gravity after the part to be inspected passes through the cleaning component 3, the part to be inspected component needs to at least overcome the gravity of the second cleaning roller 33 to push the second cleaning roller 33 to move toward the separation position when passing through the cleaning component 3. At this time, the second cleaning roller 33 squeezes the part to be inspected at least under the action of its own gravity, so that the part to be inspected is subjected to a more appropriate squeezing force during the cleaning process between the first cleaning roller 32 and the second cleaning roller 33, so as to ensure the cleaning effect of the part to be inspected.

[0261] In some embodiments of the present invention, the cleaning assembly 3 also includes an elastic reset member, which is disposed on the mounting frame 31 and pushes the second cleaning roller 33 toward the mating position. The elastic reset member can always apply a certain elastic force to the second cleaning roller 33, and the elastic force makes the second cleaning roller 33 tend to move toward the mating position, thereby ensuring that the second cleaning roller 33 is always in the mating position.

[0262] The following description takes the case where the second cleaning roller 33 is arranged on the upper side or the lower side of the first cleaning roller 32 as an example. After reading the following technical solution, those skilled in the art can easily understand the solution where the second cleaning roller 33 is arranged on other sides of the first cleaning roller 32 .

[0263] For example, the second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32, and the elastic return member can always be in a compressed state to push the second cleaning roller 33 downward toward the mating position. When the part to be detected passes through the cleaning component 3, the part to be detected presses upward against the second cleaning roller 33 to overcome the self-weight of the second cleaning roller 33 and the elastic force applied by the elastic return member, so that the second cleaning roller 33 moves upward to the separation position. After the part to be detected passes through the cleaning component 3, the part to be detected removes the force applied to the second cleaning roller 33, and the second cleaning roller 33 moves downward to the mating position under the elastic force applied by the elastic return member and its own gravity.

[0264] For example, the second cleaning roller 33 is arranged at the lower side of the first cleaning roller 32, and the elastic reset member can always be in a compressed state to overcome the self-weight of the second cleaning roller 33 and push the second cleaning roller 33 upward toward the mating position. When the part to be detected passes through the cleaning component 3, the part to be detected presses downward against the second cleaning roller 33 to overcome the elastic force applied by the elastic reset member, so that the second cleaning roller 33 moves downward to the separation position. After the part to be detected passes through the cleaning component 3, the part to be detected removes the force applied to the second cleaning roller 33, and the second cleaning roller 33 moves upward to the mating position under the elastic force applied by the elastic reset member.

[0265] Of course, the elastic reset member can also be in a stretched state all the time, which can also ensure that the second cleaning roller 33 is always in the mating position.

[0266] In some embodiments of the present invention, Fig.13 and Fig. 20 As shown, the dust-sticking roller 34 includes a rotating shaft 341, a dust-sticking member 342 and a mounting sleeve 343. The axial ends of the rotating shaft 341 are respectively rotatably matched with the mounting frame 31. The dust-sticking member 342 is a cylindrical structure, and the dust-sticking member 342 is sleeved on the outer side of the rotating shaft 341. The dust-sticking member 342 can adhere to dust on the first cleaning roller 32 and / or the second cleaning roller 33. The dust-sticking member 342 is provided with mounting sleeves 343 at both axial ends, and the mounting sleeves 343 are arranged between the rotating shaft 341 and the dust-sticking member 342. The mounting sleeves 343 are formed into a truncated cone structure 343A, and the mounting sleeves 343 are sleeved on the outside of the rotating shaft 341. The cross-sectional area of ​​the truncated cone structure 343A gradually decreases in the direction approaching the center of the rotating shaft 341. Since the outer peripheral wall of the truncated cone structure 343A is formed into a cylindrical structure, the outer peripheral wall of the truncated cone structure 343A has a certain guiding effect on the dust-sticking member 342, which is convenient for quickly completing the assembly of the mounting sleeve 343 and the dust-sticking member 342. At the same time, the dust-sticking member 342 can also be rotated relative to the mounting frame 31 to better utilize the entire outer peripheral wall of the dust-sticking member 342, so that the dust-sticking roller 34 has a larger cleaning area, which is convenient for ensuring the cleaning efficiency.

[0267] Among them, the mounting sleeve 343 and the rotating shaft 341 are slidably matched along the axial direction of the rotating shaft 341. Then, in the axial direction of the rotating shaft 341, the distance between the two mounting sleeves 343 is adjustable, so that the rotating shaft 341 can be installed with dust-sticking members 342 of different lengths. Moreover, after the dust-sticking member 342 is installed, the dust-sticking member 342 can be moved relative to the rotating shaft 341 along the axial direction of the rotating shaft 341 to adjust the position of the dust-sticking member 342 in the axial direction of the rotating shaft 341, so as to ensure that the dust-sticking member 342 better corresponds to the first cleaning roller 32 and / or the second cleaning roller 33.

[0268] Optionally, the mounting sleeve 343 can be limited in the axial direction of the rotating shaft 341 by a shaft shoulder on the rotating shaft 341 and a third bearing 3c mounted on the rotating shaft 341, so that the mounting sleeve 343 can move relative to the rotating shaft 341 within a certain range.

[0269] Optionally, the dust-sticking member 342 is dust-sticking paper.

[0270] In some embodiments of the present invention, Figure 18-Figure 20As shown, the sticky roller 34 is constructed so that the sticky roller 34 often rolls with the second cleaning roller 33 so that the sticky roller 34 directly cleans the second cleaning roller 33, and the sticky roller 34 can clean the second cleaning roller 33 in time, and clean the first cleaning roller 32 in time through the second cleaning roller 33, so that the first cleaning roller 32 and the second cleaning roller 33 can quickly prepare to clean the next part to be inspected, which is beneficial to improving the cleaning efficiency of the cleaning component 3 for cleaning multiple parts to be inspected in sequence, so that when the cleaning component 3 is used in the detection equipment, it is beneficial to improve the detection efficiency of the detection equipment.

[0271] Of course, the present application is not limited to this; in other embodiments, the sticky roller 34 can also be constructed so that the sticky roller 34 often rolls with the first cleaning roller 33 so that the sticky roller 34 directly cleans the first cleaning roller 33, and the sticky roller 34 can clean the first cleaning roller 33 in time, and clean the second cleaning roller 34 in time through the first cleaning roller 33, which is also beneficial to improving the cleaning efficiency of the cleaning component 3 for cleaning multiple parts to be inspected in sequence.

[0272] In some embodiments of the present invention, Figure 18-Figure 20 As shown, the sticky roller 34 is arranged on the upper side of the second cleaning roller 33, and the sticky roller 34 is often rolling with the second cleaning roller 33 at least under the action of its own gravity, then the sticky roller 34 has a tendency to roll with the second cleaning roller 33, and the sticky roller 34 can be often rolling with the second cleaning roller 33 only under the action of its own gravity, or it can be often rolling with the second cleaning roller 33 under the action of its own gravity and the action of other components (such as elastic members), which is convenient for simplifying the setting of the sticky roller 34, and at the same time, it is convenient for making the sticky roller 34 and the second cleaning roller 33 have a suitable extrusion force to ensure the cleaning effect of the sticky roller 34 on the second cleaning roller 33.

[0273] Of course, the present application is not limited to this; in other embodiments, the sticky roller 34 can also be arranged on the upper side of the first cleaning roller 32, and the sticky roller 34 often rolls with the first cleaning roller 32 at least under the action of its own gravity, then the sticky roller 34 has a tendency to roll with the first cleaning roller 32, the sticky roller 34 can often roll with the first cleaning roller 32 only under the action of its own gravity, or it can often roll with the first cleaning roller 32 under the action of its own gravity and the action of other components (such as elastic parts), which is convenient for simplifying the setting of the sticky roller 34, and at the same time, it is convenient to have a suitable extrusion force between the sticky roller 34 and the first cleaning roller 32 to ensure the cleaning effect of the sticky roller 34 on the second cleaning roller 33.

[0274] In some embodiments of the present invention, when the sticky roller 34 is often in rolling cooperation with the second cleaning roller 33, since the second cleaning roller 33 can move between the cooperation position and the separation position, the movement mode of the sticky roller 34 relative to the mounting frame 31 can be the same as the movement mode of the second cleaning roller 33.

[0275] For example, Fig.16 , Figure 18-Figure 20 As shown, the second cleaning roller 33 slides and cooperates with the mounting frame 31 in the up-down direction, and the sticky roller 34 also slides and cooperates with the mounting frame 31 in the up-down direction, so the sticky roller 34 can always roll and cooperate with the second cleaning roller 33 at least under the action of its own gravity, and no matter whether the second cleaning roller 33 moves to the matching position or the separation position, the sticky roller 34 can always roll and cooperate with the second cleaning roller 33. At this time, if the second cleaning roller 33 is arranged on the upper side of the first cleaning roller 32, the second cleaning roller 33 can be constructed so that the second cleaning roller 33 always rolls and cooperates with the first cleaning roller 32 at least under the action of its own gravity and the gravity of the sticky roller 34, so as to simplify the arrangement of the second cleaning roller 33 and the sticky roller 34.

[0276] Of course, the movement mode of the dust sticking roller 34 relative to the mounting frame 31 may also be different from the movement mode of the second cleaning roller 33 .

[0277] For example, the second cleaning roller 33 can rotate between the mating position and the separation position, and the corresponding rotation axis of the second cleaning roller 33 between the mating position and the separation position can be parallel to the central axis 33a of the second cleaning roller 33. In the mating position, the second cleaning roller 33 can be located directly above the first cleaning roller 32, and the second cleaning roller 33 can swing up and down; at this time, the dust-sticking roller 34 can also rotate relative to the mounting frame 31 following the rotation of the second cleaning roller 33 between the mating position and the separation position, and can also slide and cooperate with the mounting frame 31 in the up and down directions.

[0278] In some embodiments of the present invention, Fig.15 , Fig.16 , Figure 18-Figure 20 As shown, a slide groove 310 is formed on the mounting frame 31, and the slide groove 310 can extend in the up-down direction, and an end of the slide groove 310 away from the first cleaning roller 32 (for example, Fig.15 The upper end of the sticky roller 34 has an opening 310a, and the axial ends of the sticky roller 34 are respectively slidably engaged with the slide groove 310 or detached from the slide groove 310 through the opening 310a. Under the premise of ensuring that the sticky roller 34 can move up and down relative to the mounting frame 31, the axial ends of the sticky roller 34 can realize the quick disassembly and assembly of the sticky roller 34 and the mounting frame 31 through the opening 310a, so as to facilitate the quick replacement, cleaning, maintenance, etc. of the sticky roller 34.

[0279] Furthermore, if Fig.16 and Fig. 20As shown, the axial ends of the second cleaning roller 33 are respectively slidably engaged with the slide groove 310 or detached from the slide groove 310 through the opening 310a. Under the premise that the second cleaning roller 33 can be moved up and down relative to the mounting frame 31, the axial ends of the second cleaning roller 33 can realize the rapid disassembly and assembly of the second cleaning roller 33 and the mounting frame 31 through the opening 310a, so as to facilitate the rapid replacement, cleaning, maintenance, etc. of the second cleaning roller 33.

[0280] For example, in Fig.15 , Fig.17 and Fig.18 In the example, the mounting frame 31 includes a mounting seat 311 and two support seats 312. The two support seats 312 are arranged at an interval. A slide groove 310 is formed on the side of each support seat 312 facing the other support seat 312, and the sides of the two slide grooves 310 facing each other are open, and the axial ends of the dust-sticking roller 34 correspond to the two slide grooves 310 respectively.

[0281] Among them, the axial ends of the first cleaning roller 32 are rotatably matched with the two support seats 312 through the first bearing 3a respectively, and the axial ends of the second cleaning roller 33 are matched with the slide groove 310 through the second bearing 3b respectively, so that the second cleaning roller 33 can rotate around the central axis of the second bearing 3b relative to the mounting frame 31, and can move relative to the mounting frame 31 along the extension direction of the slide groove 310. The axial ends of the dust-sticking roller 34 are matched with the slide groove 310 through the third bearing 3c respectively, so that the dust-sticking roller 34 can rotate around the central axis of the third bearing 3c relative to the mounting frame 31, and can move relative to the mounting frame 31 along the extension direction of the slide groove 310.

[0282] Optionally, in Fig.15 and Fig.17 In the example, the first driving mechanism 35 includes a driving motor 351 and a transmission mechanism 352, and the driving motor 351 drives the first cleaning roller 32 to rotate through the transmission mechanism 352. Among them, the transmission mechanism 352 may include a second driving wheel 3521, a second driven wheel 3522, and a second transmission belt 3523 tensioned between the second driving wheel 3521 and the second driven wheel 3522, which has a simple structure and is easy to implement. Of course, the structure of the first driving mechanism 35 is not limited to this, and it is only necessary to ensure that the first driving mechanism 35 can drive the first cleaning roller 32 to rotate.

[0283] In some embodiments of the present invention, Fig.13 and Fig.14As shown, the appearance inspection device 100 also includes a blocking component 6. In the conveying direction, the blocking component 6 is arranged on the upstream side of the camera component 2. That is to say, in the process of conveying the part to be inspected along the conveying direction, the part to be inspected first passes through the blocking component 6 and then passes through the camera component 2, and the blocking component 6 is used to adjust the part to be inspected to a preset posture, so that the part to be inspected maintains the preset posture and is conveyed toward the camera component 2, so that the camera component 2 can collect image information of the part to be inspected in the preset posture, which is beneficial to take into account the integrity, effectiveness and accuracy of the image information collected by the camera component 2, thereby helping to improve the detection accuracy and detection efficiency of the inspection equipment.

[0284] It can be understood that the "preset posture" can be specifically set according to the needs of the camera component 2, etc.; for example, the part to be detected is formed into a square plate structure, the part to be detected is horizontally placed on the conveying component 4, and the part to be detected is horizontally conveyed along the conveying direction, and the upper and lower sides of the conveying component 4 are respectively provided with camera components 2, and the camera component 2 collects image information of the part to be detected downward, and in the preset posture, the part to be detected is still placed horizontally, and one of the edges of the part to be detected is parallel to the front-to-back direction. The shooting field of view of the camera component 2 can be a long strip structure, and the length direction of the long strip structure can be roughly parallel to the front-to-back direction. Then, the camera component 2 collects the image information of the part to be detected in the preset posture, and it can be conveyed along with the part to be detected, so that the entire part to be detected can be captured by the camera component 2.

[0285] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, the blocking assembly 6 includes a bracket 61, a blocking member 62 and a driving device 63. The driving device 63 is connected to the blocking member 62 to drive the blocking member 62 to move, so that the blocking member 62 can move between a first position and a second position relative to the bracket 61. In the first position, the blocking member 62 is suitable for adjusting the part to be detected that moves to the first preset position to a preset posture. In the second position, the blocking member 62 is suitable for avoiding the part to be detected, so that the blocking member 62 will not interfere with the continued transmission of the part to be detected along the transmission direction, which further facilitates to ensure that the part to be detected maintains the preset posture and continues to be transmitted toward the camera assembly 2.

[0286] For example, when the part to be detected moves to the first preset position, or before it moves to the first preset position, the driving device 63 drives the blocking member 62 to move to the first position to adjust the part to be detected that moves to the first preset position to a preset posture; then, the driving device 63 drives the blocking member 62 to move to the second position, at which time the blocking member 62 will not block the movement of the part to be detected, and the part to be detected can continue to be transmitted along the transmission direction toward the camera assembly 2.

[0287] It can be understood that the movement of the blocking member 62 relative to the bracket 61 can be: the blocking member 62 can be movable between the first position and the second position, or the blocking member 62 can be rotatable between the first position and the second position, then the movement direction of the blocking member 62 is relatively simple; but not limited to this, it is only necessary to ensure that the blocking member 62 can move from the first position to the second position, and can move from the second position to the first position.

[0288] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, both ends of the length of the blocking member 62 are rotatably connected to the bracket 61 respectively, and the driving device 63 includes a second driving mechanism 631 and a connecting rod 632. The second driving mechanism 631 is arranged on the bracket 61, and the second driving mechanism 631 is located at one end of the length of the blocking member 62. Both ends of the length of the connecting rod 632 are rotatably connected to the above-mentioned end of the length of the blocking member 62 and the second driving mechanism 631 respectively, then one end of the length of the connecting rod 632 is rotatably connected to the above-mentioned end of the length of the blocking member 62, and the other end of the length of the connecting rod 632 is rotatably connected to the second driving mechanism 631. The second driving mechanism 631 drives the corresponding end of the connecting rod 632 to move, and the second driving mechanism 631 drives the end of the connecting rod 632 connected to the second driving mechanism 631 to move, so as to drive the blocking member 62 to rotate relative to the bracket 61 through the connecting rod 632.

[0289] Therefore, the driving device 63 has a simple structure and is easy to implement, and it is also easy to achieve smooth rotation of the blocking member 62 between the first position and the second position.

[0290] For example, in Fig.34 and Fig.35 In the example, the second driving mechanism 631 drives the end of the connecting rod 632 connected to the second driving mechanism 631 to move up and down, and the connecting rod 632 drives the end of the blocking member 62 to rotate around the rotation axis to realize the rotation of the blocking member 62 between the first position and the second position; wherein, in the second position, the blocking member 62 can be located above the part to be detected to avoid the part to be detected. For example, the blocking member 62 can swing up and down between the first position and the second position, so that the blocking member 62 has a suitable range of motion, ensuring that the blocking member 62 can move to the first position in time to adjust the part to be detected.

[0291] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, the blocking member 62 has a blocking surface 62a, and the blocking surface 62a can be located on the side of the blocking member 62 facing the first preset position. In the first position, the blocking member 62 is suitable for blocking the movement of the part to be detected along the conveying direction so that the edge of the part to be detected is flush with the blocking surface 62a, and the edge of the part to be detected can be located in the same plane as the blocking surface 62a to adjust the part to be detected to a preset posture.

[0292] For example, in Fig.34 and Fig.35 In the example, before the detection member moves to the first preset position, the edge of the detection member facing the blocking surface 62a is inclined relative to the front-to-back direction, then the blocking surface 62a can first stop one end of the above-mentioned edge of the detection member that moves to the first preset position, and the other end of the above-mentioned edge of the detection member continues to move toward the blocking surface 62a with the movement of the conveying component until the other end of the above-mentioned edge of the detection member also stops against the blocking surface 62a, at which time the above-mentioned edge of the detection member is flush with the blocking surface 62a, and the detection member is in a preset posture.

[0293] Optionally, the blocking member 62 includes a body 621 and a baffle 622, the body 621 is arranged on the bracket 61, the baffle 622 is fixed to the body 621, and the blocking surface 62a is formed on the baffle 622. The baffle 622 is used to block the movement of the part to be detected along the conveying direction so that the edge of the part to be detected is flush with the blocking surface 62a.

[0294] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, the blocking member 62 also includes a detection device 64, which is used to detect whether the member to be detected moves to the second preset position. When the member to be detected moves to the second preset position, the driving device 63 drives the blocking member 62 to move toward the first position. In the conveying direction, the first preset position is located on the downstream side of the second preset position, so that when the member to be detected moves to the first preset position or before the member to be detected moves to the first preset position, the blocking member 62 is ensured to move to the first position, thereby ensuring that the blocking member 62 can adjust the member to be detected that moves to the first preset position to a preset posture, thereby avoiding interference between the member to be detected and the blocking member 62.

[0295] Among them, "in the conveying direction, the first preset position is located on the downstream side of the second preset position" can be understood as that the part to be detected is conveyed along the conveying direction, and the part to be detected first moves to the second preset position, and then moves from the second preset position along the conveying direction to the first preset position.

[0296] For example, the detection device 64 can be connected to the driving device 63. When the detection device 64 detects that the part to be detected moves to the second preset position, the detection device 64 can transmit a signal to the driving device 63. The driving device 63 can immediately drive the blocking member 62 to move toward the first position, or can drive the blocking member 62 to move toward the first position after a predetermined time. It is only necessary to ensure that the moment when the blocking member 62 moves to the first position is no later than the moment when the part to be detected moves to the first preset position.

[0297] It can be understood that, in the conveying direction, the distance between the second preset position and the first preset position can be specifically set according to the conveying speed of the part to be detected, the moving speed of the blocking member 62 and the like.

[0298] Optionally, the detection device 64 is a sensor.

[0299] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, the bracket 61 includes a support shaft 611, and the two ends of the length of the blocking member 62 are respectively connected to the support shaft 611 for rotation, so that the blocking member 62 can rotate around the central axis of the support shaft 611, so as to ensure that the blocking member 62 is stably arranged on the bracket 61 and the blocking member 62 rotates smoothly. Among them, the detection device 64 is arranged on the support shaft 611, so that the rotation of the blocking member 62 relative to the bracket 61 will not interfere with the detection device 64, which facilitates the arrangement of the detection device 64.

[0300] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, the detection device 64 and the support shaft 611 are axially slidably matched along the support shaft 611, and the position of the detection device 64 in the axial direction of the support shaft 611 can be adjusted so that the detection device 64 can better match the parts to be detected with different structures and sizes, which is beneficial to improving the applicability of the blocking assembly 6.

[0301] For example, the part to be detected may include a metal part, and the detection device 64 can determine whether the part to be detected has moved to the second preset position by detecting the metal part; for parts to be detected with different structures and sizes, the setting of the metal part is different, and the position of the detection device 64 can be adjusted to adapt to different parts to be detected.

[0302] In some embodiments of the present invention, Fig.34 and Fig.35 As shown, the support shaft 611 is provided through the detection device 64, and a locking member 65 is provided between the detection device 64 and the support shaft 611. The locking member 65 is provided through the detection device 64, and the locking member 65 is threadedly matched with the detection device 64. The locking member 65 is suitable for abutting against the support shaft 611 to limit the movement of the detection device 64 relative to the support shaft 611. When the locking member 65 is tightened, the locking member 65 can be tightly abutted against the outer peripheral wall of the support shaft 611, so that the detection device 64 is stably fixed to the support shaft 611. When the locking member 65 is loosened, the locking member 65 can be spaced from the outer peripheral wall of the support shaft 611, so that the detection device 64 can slide relative to the support shaft 611 to adjust the position of the detection device 64 in the axial direction of the support shaft 611. Therefore, by setting the locking member 65, the stable installation of the detection device 64 can be achieved under the premise of ensuring that the detection device 64 can slide relative to the support shaft 611.

[0303] In some embodiments of the present invention, Fig.21 As shown, the camera assembly 2 includes a bracket 21, a camera device 22 and an adjusting device 23. The camera device 22 is used to collect image information of the part to be detected. The adjusting device 23 is arranged on the bracket 21, and the adjusting device 23 includes a first adjusting mechanism 231 and a second adjusting mechanism 232. The first adjusting mechanism 231 is used to drive the camera device 22 to rotate around the first axis 2a relative to the bracket 21, and the second adjusting mechanism 232 is used to drive the camera device 22 to rotate around the second axis 2b relative to the bracket 21. The angle between the first axis 2a and the second axis 2b is non-zero.

[0304] Among them, Fig. 22 As shown, one of the first axis 2a and the second axis 2b is parallel to or coincides with the shooting center line 22b of the camera device 22, so that one of the first axis 2a and the second axis 2b relative to the first adjustment mechanism 231 or the second adjustment mechanism 232 can be used to adjust the posture of the shooting field of view of the camera device 22 relative to the object to be detected, and the other can be used to adjust the position of the shooting field of view relative to the object to be detected.

[0305] For example, when the first axis 2a is parallel to the shooting center line 22b of the camera 22, the first adjustment mechanism 231 can be used to adjust the position and posture of the shooting field of view relative to the part to be detected, and the second adjustment mechanism 232 is used to adjust the position of the shooting field of view relative to the part to be detected. When the second axis 2b is parallel to the shooting center line 22b of the camera 22, the second adjustment mechanism 232 can be used to adjust the position and posture of the shooting field of view relative to the part to be detected, and the first adjustment mechanism 231 is used to adjust the position of the shooting field of view relative to the part to be detected.

[0306] When the first axis 2a coincides with the shooting center line 22b of the camera device 22 (eg Fig. 22 and Fig.24 When the second axis 2b coincides with the shooting center line 22b of the camera 22, the second adjustment mechanism 232 can be used to adjust the posture of the shooting field of view relative to the object to be detected, and the first adjustment mechanism 231 is used to adjust the position of the shooting field of view relative to the object to be detected.

[0307] It can be understood that when one of the first axis 2a and the second axis 2b is parallel to the shooting center line 22b, the distance between the above one of the first axis 2a and the second axis 2b and the shooting center line 22b can be specifically set according to actual conditions, for example, it can be set according to the size of the shooting field of view, so that the orthographic projection of the above one of the first axis 2a and the second axis 2b along the shooting direction falls within the shooting field of view.

[0308] Thus, the camera device 22 can be installed on the bracket 21 by the adjusting device 23, and after the camera device 22 is installed or when the camera device 22 is used, the camera device 22 can be adjusted to rotate by the first adjusting mechanism 231 and the second adjusting mechanism 232, so as to adjust the shooting field of the camera device 22 relative to the position and posture of the part to be detected, so that the camera device 22 can shoot the entire part to be detected to obtain complete image information, avoid omission of image information, and help improve detection efficiency. For example, in the process of collecting image information, if the camera device 22 and the part to be detected are relatively moved so that the camera device 22 scans the entire part to be detected, then the first adjusting mechanism 231 and the second adjusting mechanism 232 are convenient for making the position and posture of the shooting field of the camera device 22 match the part to be detected, so as to effectively ensure that the camera device 22 can collect the complete image information of the entire part to be detected.

[0309] For example, in Fig.21 and Fig.28 In the example, the part to be detected may be located below the camera device 22, and the camera device 22 shoots downward to collect image information of the part to be detected. The horizontal direction may include a first direction perpendicular to each other (for example, Fig.21 and Fig.28 , left-right direction) and a second direction (e.g., Fig. 20 and Fig.28 The shooting field of view of the camera device 22 may be a long strip structure, the length of which may be greater than the width of the to-be-detected part in the second direction. During the acquisition process, the to-be-detected part may be along the first direction (for example, Fig.28 If the part to be inspected is opposite to the shooting field of view at this time, and the length direction of the long strip structure corresponding to the shooting field of view is parallel to the second direction, each part of the part to be inspected can be effectively made to pass through the shooting field of view of the camera device 22 in sequence, thereby ensuring that the camera device 22 obtains complete image information.

[0310] However, due to processing errors, the fasteners used to install the camera device 22 apply a certain preload to the camera device 22, etc., it is easy to cause the long strip structure corresponding to the camera device 22 shooting field of view to deviate from the above-mentioned ideal state. At this time, the camera device 22 can be driven to rotate by the second adjustment mechanism 232 to adjust the position of the shooting field of view relative to the part to be detected. For example, the second adjustment mechanism 232 can adjust the position of the shooting field of view in the second direction, so that the shooting field of view is relative to the part to be detected, and avoid the shooting field of view and the part to be detected from being misaligned in the second direction, and the camera device 22 is driven to rotate by the first adjustment mechanism 231 to adjust the posture of the shooting field of view relative to the part to be detected, so that the long strip structure corresponding to the shooting field of view rotates to a posture in which its length direction is substantially parallel to the second direction, so that each part of the part to be detected moves in turn along the first direction to pass through the shooting field of view range. Of course, it can also be that the first adjustment mechanism 231 adjusts the position of the shooting field of view relative to the part to be detected, and the second adjustment mechanism 232 adjusts the posture of the shooting field of view relative to the part to be detected.

[0311] Alternatively, if Fig. 22 , Fig.24 and Fig.26 As shown, the first axis 2a is perpendicular to the second axis 2b, that is, no matter how much the first adjustment mechanism 231 and the second adjustment mechanism 232 drive the camera device 22 to rotate, the first axis 2a and the second axis 2b always remain perpendicular, so as to quickly complete the adjustment of the camera device 22.

[0312] Among them, Fig. 22 and Fig.24 As shown, the first axis 2a coincides with the shooting center line 22b of the camera device 22, and the first adjustment mechanism 231 can be used to adjust the posture of the shooting field of view relative to the part to be detected, and the second adjustment mechanism 232 is used to adjust the position of the shooting field of view relative to the part to be detected. The first adjustment mechanism 231 will not change the position of the shooting field of view relative to the part to be detected during the adjustment process, and the second adjustment mechanism 232 will not change the posture of the shooting field of view relative to the part to be detected during the adjustment process.

[0313] Of course, when the second axis 2b coincides with the shooting center line 22b of the camera device 22, the second adjustment mechanism 232 can be used to adjust the posture of the shooting field of view relative to the part to be detected, and the first adjustment mechanism 231 is used to adjust the position of the shooting field of view relative to the part to be detected. The second adjustment mechanism 232 will not change the position of the shooting field of view relative to the part to be detected during the adjustment process, and the first adjustment mechanism 231 will not change the posture of the shooting field of view relative to the part to be detected during the adjustment process.

[0314] In some embodiments of the present invention, Fig. 22 and Fig.24As shown, the adjusting device 23 further includes an adapter frame 233, and the camera device 22 is rotatably mounted on the adapter frame 233. For example, the camera device 22 can be rotatably matched with the adapter frame 233 through a bearing.

[0315] For example, the first adjustment mechanism 231 directly drives the adapter 233 to rotate around the first axis 2a, and the second adjustment mechanism 232 directly drives the camera device 22 to rotate around the second axis 2b relative to the adapter 233. Then, the camera device 22 can be directly arranged on the second adjustment mechanism 232 to be driven to rotate by the second adjustment mechanism 232, and the adapter 233 can drive the second adjustment mechanism 232 and the camera device 22 to rotate together. Thus, the connection between the first adjustment mechanism 231, the second adjustment mechanism 232 and the adapter 233 is facilitated, so that the first adjustment mechanism 231 and the second adjustment mechanism 232 can respectively drive the camera device 22 to rotate, so that the rotation of the camera device 22 around the first axis 2a and the rotation around the second axis 2b are independent of each other and do not interfere with each other.

[0316] For another example, the second adjustment mechanism 232 directly drives the adapter 233 to rotate around the second axis 2b, and the first adjustment mechanism 231 directly drives the camera device 22 to rotate around the first axis 2a relative to the adapter 233. Then, the camera device 22 can be directly arranged on the first adjustment mechanism 231 to be driven to rotate by the first adjustment mechanism 231, and the adapter 233 can drive the first adjustment mechanism 231 and the camera device 22 to rotate together. Thus, the connection between the first adjustment mechanism 231, the second adjustment mechanism 232 and the adapter 233 is also facilitated, ensuring that the first adjustment mechanism 231 and the second adjustment mechanism 232 can respectively drive the camera device 22 to rotate.

[0317] Optionally, in Fig. 22 and Fig.24 In the example, the adapter frame 233 includes a first adapter plate 2331 and a second adapter plate 2332, and one end edge of the first adapter plate 2331 is connected to one end edge of the second adapter plate 2332, so that the adapter frame 233 is roughly formed into an L-shaped structure; the camera device 22 is rotatably matched with the first adapter plate 2331 through a first mounting bearing 233E, and the second adjustment mechanism 232 directly drives the second adapter plate 2332 to rotate around the second axis 2b, and the second adapter plate 2332 can be rotatably matched with the bracket 21 through a pivot shaft 233G, and a second mounting bearing 233F can be provided between the second adapter plate 2332 and the pivot shaft 233G.

[0318] In some embodiments of the present invention, Fig. 22 and Fig.24As shown, the camera device 22 has a first matching portion 22a, the first adjustment mechanism 231 directly drives the camera device 22 to rotate, and the first adjustment mechanism 231 includes a first fixed member 2311 and a first movable member 2312, the first fixed member 2311 is fixed to the adapter 233, the first movable member 2312 is arranged on the first fixed member 2311, and the first movable member 2312 can move relative to the first fixed member 2311 to drive the camera device 22 to rotate through the first matching portion 22a. Therefore, the first adjustment mechanism 231 can drive the camera device 22 to rotate around the first axis 2a relative to the adapter 233.

[0319] Optionally, the camera device 22 may include a camera body and a mounting member, the camera body is fixed to the mounting member, and the first matching portion 22a is formed on the mounting member or the camera body. The camera body may be a camera, and the camera has a lens, which can scan the object to be inspected to collect image information.

[0320] In some embodiments, the first movable member 2312 is configured to drive the camera device 22 to rotate bidirectionally around the first axis 2a through the first matching portion 22a, that is, the first movable member 2312 can drive the camera device 22 to rotate forwardly around the first axis 2a, and can also drive the camera device 22 to rotate reversely around the first axis 2a. For example, the first movable member 2312 can be connected to the first matching portion 22a; for another example, the first matching portion 22a is formed as a convex structure, and a limiting groove is formed on the first movable member 2312, the first matching portion 22a is matched with the limiting groove, and the first matching portion 22a and the limiting groove are matched in the circumferential upper limit around the first axis 2a, so that the opposite side walls of the limiting groove can limit the rotation of the first matching portion 22a around the first axis 2a.

[0321] Of course, the present application is not limited to this; for example, the first movable member 2312 can also be configured to drive the camera device 22 to rotate unidirectionally around the first axis 2a through the first matching portion 22a, that is, the first movable member 2312 can only drive the camera device 22 to rotate forward or reversely around the first axis 2a; at this time, the first movable member 2312 can be stop-fitted with the first matching portion 22a, and the movement of the first movable member 2312 is not easy to interfere with the rotation of the first matching portion 22a around the first axis 2a, thereby ensuring smooth adjustment of the first adjustment mechanism 231 and helping to simplify the structure of the first adjustment mechanism 231.

[0322] In some embodiments, Fig. 22 and Fig.24As shown, the first movable member 2312 can move relative to the first fixed member 2311, so the movement mode of the first movable member 2312 is simple, which is convenient for simplifying the structure of the first adjustment mechanism 231. At this time, if the first movable member 2312 is configured to drive the camera device 22 to rotate bidirectionally around the first axis 2a, the first movable member 2312 can push the first matching portion 22a to realize the positive rotation of the camera device 22 around the first axis 2a, and the first movable member 2312 can push the first matching portion 22a to realize the reverse rotation of the camera device 22 around the first axis 2a; if the first movable member 2312 is configured to drive the camera device 22 to rotate unidirectionally around the first axis 2a, the first movable member 2312 can push or push back to realize the unidirectional rotation of the camera device 22.

[0323] Optionally, the first movable member 2312 is threadedly matched with the first fixed member 2311, so as to facilitate the stepless movement of the first movable member 2312 relative to the first fixed member 2311, so that the first movable member 2312 can be at any position within its moving range, which is conducive to improving the adjustment flexibility of the first adjustment mechanism 231, so that the first adjustment mechanism 231 is better suitable for camera devices 22 with different degrees of deviation, and ensures the installation accuracy of the camera device 22. In addition, it is convenient to achieve self-locking of the first movable member 2312 and the first fixed member 2311, and there is no need to set up a separate locking mechanism (for example, the first locking mechanism described later).

[0324] Of course, in other embodiments of the present application, the first movable member 2312 may also rotate relative to the first fixed member 2311 to realize the rotation of the camera device 22 around the first axis 2a.

[0325] Optionally, in Fig. 22 and Fig.24 In the example, the first matching portion 22a can be formed as a protruding structure; of course, the first matching portion 22a can also be formed as other structures, such as a groove structure, etc., as long as the first movable member 2312 can drive the camera device 22 to rotate through the first matching portion 22a.

The first movable member 2312 is threadedly matched with the first fixed member 2311, so as to achieve fine adjustment of the first adjustment mechanism 231, so that the first adjustment mechanism 231 has good adjustment accuracy.

[0327] Optionally, the first restoring member 2313 is an elastic member, which can be often in a compressed state and often push the first matching portion 22a toward the first movable member 2312, so that the first matching portion 22a has a tendency to move toward the first movable member 2312 under the action of the first restoring member 2313, so as to ensure that the first restoring member 2313 and the first matching portion 22a are always in abutment with each other, and the first matching portion 22a and the first movable member 2312 are always in abutment with each other.

Thus, the second adjustment mechanism 232 can drive the adapter frame 233 to rotate relative to the bracket 21 around the second axis 2b.

[0330] In some embodiments, the second movable member 2322 is configured to drive the adapter frame 233 to rotate bidirectionally around the second axis 2b through the second matching portion 233a, that is, the second movable member 2322 can drive the adapter frame 233 to rotate forward around the second axis 2b, and can also drive the adapter frame 233 to rotate reversely around the second axis 2b. For example, the second movable member 2322 can be connected to the second matching portion 233a; for another example, the second matching portion 233a is formed as a protruding structure, and a limiting groove is formed on the second movable member 2322, the second matching portion 233a is matched with the limiting groove, and the second matching portion 233a and the limiting groove are matched in the circumferential upper limit around the second axis 2b, so that the opposite side walls of the limiting groove can limit the rotation of the second matching portion 233a around the second axis 2b.

[0331] Of course, the present application is not limited to this; for example, the second movable member 2322 can also be configured to drive the adapter frame 233 to rotate unidirectionally around the second axis 2b through the second matching portion 233a, that is, the second movable member 2322 can only drive the adapter frame 233 to rotate forward or reversely around the second axis 2b; at this time, the second movable member 2322 can be stop-fitted with the second matching portion 233a, and the movement mode of the second movable member 2322 is not easy to interfere with the rotation of the second matching portion 233a around the second axis 2b, thereby ensuring smooth adjustment of the second adjustment mechanism 232 and helping to simplify the structure of the second adjustment mechanism 232.

[0332] In some embodiments, Fig. 22 and Fig.24 As shown, the second movable member 2322 can move relative to the second fixed member 2321, so the movement mode of the second movable member 2322 is simple, which is convenient for simplifying the structure of the second adjustment mechanism 232. At this time, if the second movable member 2322 is configured to drive the adapter frame 233 to rotate bidirectionally around the second axis 2b, the second movable member 2322 can push the second matching portion 233a to realize the forward rotation of the adapter frame 233 around the second axis 2b, and the second movable member 2322 can push the second matching portion 233a to realize the reverse rotation of the adapter frame 233 around the second axis 2b; if the second movable member 2322 is configured to drive the adapter frame 233 to rotate unidirectionally around the second axis 2b, the second movable member 2322 can push or push back to realize the unidirectional rotation of the adapter frame 233.

[0333] Optionally, the second movable member 2322 is threadedly matched with the second fixed member 2321, so as to facilitate the stepless movement of the second movable member 2322 relative to the second fixed member 2321, so that the second movable member 2322 can be at any position within its moving range, which is conducive to improving the adjustment flexibility of the second adjustment mechanism 232, so that the second adjustment mechanism 232 is better suitable for camera devices 22 with different degrees of deviation, and ensures the installation accuracy of the camera device 22. In addition, it is convenient to achieve self-locking of the second movable member 2322 and the second fixed member 2321, and there is no need to set up a separate locking mechanism (for example, the second locking mechanism 242 described later).

[0334] Of course, in other embodiments of the present application, the second movable member 2322 may also rotate relative to the second fixed member 2321 to achieve the rotation of the adapter frame 233 around the second axis 2b.

[0335] Optionally, in Fig. 22 and Fig.24 In the example, the second matching portion 233a can be formed as a protruding structure; of course, the second matching portion 233a can also be formed as other structures, such as a groove structure, etc., as long as the second movable member 2322 can drive the adapter frame 233 to rotate through the second matching portion 233a.

The second movable member 2322 is threadedly matched with the second fixed member 2321, so as to achieve fine adjustment of the second adjustment mechanism 232, so that the second adjustment mechanism 232 has good adjustment accuracy.

[0337] Optionally, the second restoring member 2323 is an elastic member, which can be often in a compressed state and often push the second matching portion 233a toward the second movable member 2322, so that the second matching portion 233a has a tendency to move toward the second movable member 2322 under the action of the second restoring member 2323, so as to ensure that the second restoring member 2323 and the second matching portion 233a are always in abutment with each other, and the second matching portion 233a and the second movable member 2322 are always in abutment with each other.

When the first locking mechanism locks the first adjustment mechanism 231, the first locking mechanism is penetrated in the first matching hole to fix the camera device 22 and the adapter 233.

Among them, the "acquisition distance" can be understood as the distance between the camera device 22 and the part to be detected along the shooting direction of the camera device 22.
