DETAILED DESCRIPTION

[0032] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.

[0033] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0034] The utility model proposes a conveying assembly 100', which can adjust the position of the detection object, and is convenient for subsequent detection of the detection object. In addition, an online detection equipment 1000 including the aforementioned conveying assembly 100' is also proposed.

[0035] As Figures 1 to 5 According to the conveying assembly 100' of the utility model embodiments, the conveying assembly 100' comprises a first mounting frame 10, a conveying structure 20, a first limiting piece 31, a second limiting piece 32 and a driving structure 40.

[0036] The conveying structure 20 is arranged on the first mounting frame 10 and is used to convey the articles in a first horizontal direction, and the conveying structure 20 comprises a plurality of conveying members 21 arranged at intervals in the first horizontal direction, and each conveying member 21 is rotatably arranged on the first mounting frame 10; when it is necessary to detect the articles, the plurality of conveying members 21 can be rotated relative to the first mounting frame 10 to roll the articles to be detected to a preset detection position, so as to facilitate the detection instrument to detect the articles to be detected; for example, the articles to be detected are PCB boards, and the detection instrument is used to detect the scratches or depressions on the surfaces of the PCB boards, so as to timely screen out the defective PCB boards.

[0037] However, the position of the articles to be detected entering the conveying structure 20 cannot be guaranteed, so that the detection instrument cannot well detect the articles to be detected; therefore, the first limiting member 31 and the second limiting member 32 can be arranged, and the conveying structure 20 has a preset conveying area arranged at intervals between two ends of the conveying member 21 in a second horizontal direction; it can be understood that the preset conveying area has an interval with one end of the conveying member 21 and has an interval with the other end of the conveying member 21, and the articles to be detected are moved to the preset conveying area through the limiting cooperation between the first limiting member 31 and the second limiting member 32, so as to facilitate the conveying structure 20 to convey the articles to be detected to the preset detection position for detection.

[0038] Specifically, the first limiting member 31 and the second limiting member 32 are arranged in sequence in the second horizontal direction, and at least one of the two is configured as a movable limiting member, and the movable limiting member can be moved relative to the first mounting frame 10 in the second horizontal direction; the driving structure 40 is arranged on the first mounting frame 10 and is used to drive the movable limiting member to move, so as to push the articles to be detected to the preset conveying area in the second horizontal direction; the second horizontal direction is perpendicular to the first horizontal direction; in other words, before the conveying structure 20 conveys the articles to be detected to the preset detection position, the movable limiting member can drive the articles to be detected to be pushed to the preset conveying area in the second horizontal direction, so as to facilitate the conveying structure 20 to convey the articles to be detected to the preset detection position, and improve the detection accuracy of the articles to be detected; and the first limiting member 31 and the second limiting member 32 can limit the articles to be detected from falling off from the conveying structure 20 in the second horizontal direction, and improve the conveying stability of the conveying assembly 100'.

[0039] In summary, according to the conveying assembly 100' of the embodiment of the utility model, through the limiting cooperation of the first limiting member 31 and the second limiting member 32, the position degree of the articles to be detected can be adjusted, so as to facilitate the subsequent detection of the articles to be detected, and for the articles to be detected of different widths conveyed to the conveying structure 20, the articles to be detected can be well positioned in the second horizontal direction, and are all pushed to the preset conveying area, so as to facilitate the subsequent detection of the articles to be detected.

[0040] It needs to be understood that there are various ways to constitute the movable limiting member; in the first example, the first limiting member 31 constitutes the movable limiting member, and the first limiting member 31 pushes the to-be-detected article in the second horizontal direction; in the second example, the second limiting member 32 constitutes the movable limiting member, and the second limiting member 32 pushes the to-be-detected article; in the third example, both the first limiting member 31 and the second limiting member 32 constitute the movable limiting member, and the first limiting member 31 and the second limiting member 32 cooperate to push the to-be-detected article.

[0041] It can also be understood that the preset conveying area can be an area that is always constant, for example, the position of the preset conveying area relative to the first mounting frame 10 in the second horizontal direction and the width of the preset conveying area in the second horizontal direction are both constant; or the preset conveying area can also be constituted as an area that can be adaptively adjusted according to the shape, size, etc. of the article, for example, the position of the preset conveying area relative to the first mounting frame 10 in the second horizontal direction and / or the width of the preset conveying area in the second horizontal direction can be adaptively adjusted according to different parameters of the article.

[0042] In addition, for the convenience of understanding, the following embodiments are mainly described in combination with the second example if no special description is given.

[0043] According to the second example, as Figures 1 to 5 , the first limiting member 31 is fixedly arranged on the first mounting frame 10, and the second limiting member 32 constitutes a movable limiting member. For example, when the to-be-detected article enters the conveying structure 20, the to-be-detected article is limited by the first limiting member 31 and the second limiting member 32 to avoid falling off the conveying structure 20; then the second limiting member 32 is powered by the driving structure 40 to push the to-be-detected article to the preset conveying area, and finally the to-be-detected article is conveyed to the preset detection position by the plurality of conveying members 21, so as to facilitate the detection instrument to detect the to-be-detected article and improve the detection accuracy.

[0044] In addition, the first limiting member 31 is arranged adjacent to one end of the plurality of conveying members 21 in the second horizontal direction; specifically, the plurality of conveying members 21 have opposite two ends in the second horizontal direction, and the first limiting member 31 is more adjacent to one end of the plurality of conveying members 21 relative to the other end of the plurality of conveying members 21, so as to facilitate the fixed arrangement of the first limiting member 31, while reducing the interference of the first limiting member 31 and the second limiting member 32 on the conveying space, which is conducive to increasing the width of the space for conveying articles provided by the conveying structure 20 in the second horizontal direction, facilitating the conveying structure 20 to be used for conveying more kinds of articles of different specifications, and facilitating the to-be-detected article to enter the conveying structure 20.

[0045] In combination with the foregoing, it needs to be understood that the preset conveying area is an area artificially divided corresponding to the preset detection position of the detection instrument, and when the preset detection position of the detection instrument changes, the preset conveying area also adjusts accordingly; based on this, the first limiting piece 31 can be arranged at the edge of the preset conveying area away from the second limiting piece 32 along the second horizontal direction, and when the conveying structure 20 conveys the to-be-detected article, the first limiting piece 31 can guide the to-be-detected article to be conveyed to the preset detection position, avoiding the to-be-detected article deviating from the predetermined track during the conveying process.

[0046] For example, Figure 1 In some embodiments of the present application, the conveying assembly 100' further comprises a first sensor 51, and the first sensor 51 communicates with the driving structure 40. For example, when the first sensor 51 detects that the to-be-detected article is located in the preset conveying area, a signal for stopping driving is sent to the driving structure 40, avoiding the second limiting piece 32 continuing to push, resulting in the to-be-detected article position deviating again.

[0047] Specifically, the detection head of the first sensor 51 is arranged towards the conveying surface of the conveying structure 20, and the orthographic projection of the detection head of the first sensor 51 on the horizontal plane is located in the preset conveying area; in this way, when the in-line detection equipment 1000 works, the to-be-detected article can enter the conveying surface of the conveying structure 20, the conveying surface has a preset conveying area corresponding to the predetermined position of the detection instrument, and the second limiting piece 32 can push the to-be-detected article to the preset conveying area along the second horizontal direction, at this time, the detection head of the first sensor 51 can detect that the to-be-detected article is in place, and notify the driving structure 40 to stop driving the second limiting piece 32.

[0048] It needs to be explained that the conveying surface of the conveying structure 20 is formed by the same side surfaces of a plurality of conveying pieces 21, for example, the outer peripheral wall of the conveying piece 21 is a cylindrical surface, and the conveying surface can be a horizontal plane tangent to the outer peripheral wall of the plurality of conveying pieces 21. The power of the conveying structure 20 is not limited in the embodiments of the present application, for example, the conveying piece 21 can be configured as a magnetic roller, and the conveying structure 20 can apply a driving force to the magnetic roller to make it rotate by magnetic force; but not limited thereto.

[0049] Further, as Figure 9The detection head interval of the first sensor 51 is arranged on the side of the first limiting piece 31 facing the second limiting piece 32, and the distance between the detection head of the first sensor 51 and the first limiting piece 31 in the second horizontal direction is h, 2mm≤h≤3mm, so that the first sensor 51 is used to detect whether the article is pushed to the preset conveying area; it can be understood that if the interval h<2mm, when the second limiting piece 32 pushes the article to be detected, the detection head of the first sensor 51 is not triggered or slowly triggered, which causes the article to be detected to be easily damaged by the large clamping force applied by the first limiting piece 31 and the second limiting piece 32; in addition, if the interval h>3mm, when the second limiting piece 32 pushes the article to be detected, the detection head of the first sensor 51 is easily triggered in advance, and at this time the article to be detected is not completely placed in the preset conveying area. Therefore, the distance h between the detection head of the first sensor 51 and the first limiting piece 31 in the second horizontal direction satisfies the relationship 2mm≤h≤3mm, so as to ensure the pushing accuracy of the second limiting piece 32 and avoid damage to the article to be detected or cause the detection instrument to be unable to detect the article to be detected. Wherein, according to the actual situation, the interval h can be 2mm, 2.25mm, 2.5mm, 2.75mm, 3mm, etc.

[0050] As Figures 1 to 4 、 Figure 7 In some embodiments of the utility model, the conveying assembly 100' further includes a second mounting frame 60, the second mounting frame 60 is arranged on the first mounting frame 10, and the second mounting frame 60 includes a first leg 61, a second leg 62 and a connecting beam 63, the first leg 61 and the second leg 62 are respectively arranged on both sides of the conveying structure 20 in the second horizontal direction, and the connecting beam 63 is arranged above the conveying structure 20 and connects the upper end of the first leg 61 and the upper end of the second leg 62; in this way, the second mounting frame 60 of U-shaped structure can be constructed, the second mounting frame 60 can provide mounting points for the driving structure 40, and is avoided with the conveying structure 20, to avoid interference between the driving structure 40 and the article to be detected, and to ensure normal conveying of the conveying structure 20 to the article to be detected; moreover, it is convenient to realize the stable arrangement of the second mounting frame 60, so that the second mounting frame 60 can provide reliable mounting points for other components, and the moving reliability of the movable limiting piece is improved.

[0051] In addition, the driving structure 40 is arranged on the connecting beam 63, the driving structure 40 includes a driver 41 and a transmission structure 42, and the transmission structure 42 connects the driver 41 and the movable limiting piece; in this way, the driver 41 and the transmission structure 42 can be arranged on the connecting beam 63 above the conveying structure 20, and are avoided in space position with the conveying structure 20 and the article to be detected on the conveying structure 20, and drive the movable limiting piece to move along the second horizontal direction, to realize the position adjustment of the article to be detected.

[0052] The driver 41 can be a driving motor, and the driving motor driving shaft rotation is converted into the linear motion of the movable limiting part along the second horizontal direction through the transmission structure 42 to meet the adjustment requirement of the to-be-detected article.

[0053] The transmission structure 42 can have various transmission forms, and the utility model specifically provides the following implementation manners for description:

[0054] Implementation manner 1

[0055] The transmission structure 42 is in the form of chain transmission: the transmission structure 42 comprises a driving wheel 421, a driven wheel 422 and a transmission chain, the driving wheel 421 is connected with the driver 41, the transmission chain is wound on the driving wheel 421 and the driven wheel 422, and the movable limiting part is fixed with the transmission chain through the adapter structure 70; specifically, the driving wheel 421 and the driven wheel 422 are arranged along the second horizontal direction, so that the transmission chain wound on the driving wheel 421 and the driven wheel 422 extends along the second horizontal direction; in work, the driver 41 can drive the driving wheel 421 to rotate, and power is transmitted to the transmission chain, the driven wheel 422 cooperates to tension the transmission chain to ensure the transmission stability, and the movable limiting part moves along the second horizontal direction with the transmission chain to realize the position adjustment of the to-be-detected article.

[0056] Implementation manner 2

[0057] The transmission structure 42 is in the form of belt transmission: as Figures 1 to 3 , the transmission structure 42 comprises a driving wheel 421, a driven wheel 422 and a transmission belt 423, the driving wheel 421 is connected with the driver 41, the transmission belt 423 is wound on the driving wheel 421 and the driven wheel 422, and the movable limiting part is fixed with the transmission belt 423 through the adapter structure 70; specifically, the driving wheel 421 and the driven wheel 422 are arranged along the second horizontal direction, so that the transmission belt 423 wound on the driving wheel 421 and the driven wheel 422 extends along the second horizontal direction; in work, the driver 41 can drive the driving wheel 421 to rotate, and power is transmitted to the transmission belt 423, the driven wheel 422 cooperates to tension the transmission belt 423 to ensure the transmission stability, and the movable limiting part moves along the second horizontal direction with the transmission belt 423 to realize the position adjustment of the to-be-detected article.

[0058] Further, the distance between the driving wheel 421 and the driven wheel 422 along the second horizontal direction is greater than or equal to the length of the conveying part 21 along the second horizontal direction; in this way, the movement range of the movable limiting part can be increased, so that the position adjustment of the to-be-detected article is better realized, and the width of the preset conveying area can be adjusted by adjusting the stroke of the movable limiting part to adapt to articles of different widths.

[0059] Further, the conveying assembly 100' further comprises a support rail 80, the support rail 80 extends along the second horizontal direction and is arranged on the connecting beam 63, the support rail 80 is in sliding fit with the adapter structure 70 along the second horizontal direction, in this way, the support rail 80 can provide guidance for the movement of the movable limiting member in the second horizontal direction, so as to improve the movement stability of the movable limiting member, and facilitate the adjustment of the position degree of the to-be-detected article.

[0060] In addition, the support rail 80 and the adapter structure 70 are in limiting fit in the up-down direction, so as to limit the adapter structure 70 from being separated from the support rail 80, and provide support for the adapter structure 70, so as to reduce the damage probability of the conveying belt 423; it can be understood that the conveying belt 423 has flexible properties, and under the action of gravity, the conveying belt 423 is in a suspended state, thus, the driven wheel 422 and the driving wheel 421 need to be in tension fit, so as to improve the transmission stability, and the adapter structure 70 is fixed on the conveying belt 423, and the adapter structure 70 pulls down the conveying belt 423 under the action of gravity, which affects the transmission stability of the conveying belt 423, thus, the limiting fit of the support rail 80 and the adapter structure 70 in the up-down direction can provide support for the adapter structure 70, so as to reduce the influence on the conveying belt 423 and improve the transmission stability.

[0061] In some embodiments, the distance between the driving wheel 421 and the driven wheel 422 in the second horizontal direction is greater than or equal to the length of the conveying member 21, and the conveying assembly 100' further comprises a support rail 80, the support rail 80 is arranged on the connecting beam 63, the support rail 80 is in sliding fit with the adapter structure 70 along the second horizontal direction, and the support rail 80 and the adapter structure 70 are in limiting fit in the up-down direction.

[0062] As Figures 1 to 5 In some embodiments of the utility model, the adapter structure 70 comprises a first clamping component 71 and a second clamping component 72 fixedly connected, and the conveying belt 423 is clamped between the first clamping component 71 and the second clamping component 72, in this way, the first clamping component 71 and the second clamping component 72 can move along with the conveying belt 423, so as to realize the adjustment of the position degree of the to-be-detected article in the second horizontal direction; and through the clamping and positioning of the first clamping component 71 and the second clamping component 72 on the conveying belt 423, the conveying belt 423 can be connected without damaging the structure of the conveying belt 423, and the service life of the conveying belt 423 can be improved.

[0063] The first clamping component 71 is formed in a plate structure, simple in structure and low in cost. The side surface of the first clamping component 71 towards the second clamping component 72 is provided with a plurality of clamping ribs 711 arranged at intervals, and each clamping rib 711 extends along the width direction of the conveying belt 423. During clamping, the plurality of clamping ribs 711 of the first clamping component 71 clamps the conveying belt 423 in cooperation with the second clamping component 72. It can be understood that the plurality of clamping ribs 711 increases the roughness of the first clamping component 71, so as to increase the friction coefficient between the conveying belt 423 and the first clamping component 71, the clamping surface pressure, prevent the conveying belt 423 from slipping with the adapter structure 70, and affect the movement of the movable limiting piece.

[0064] Further, the second clamping component 72 is formed with a limiting groove 721 on the side surface towards the first clamping component 71, and the conveying belt 423 is limitedly fitted in the limiting groove 721. In this way, when the adapter structure 70 is assembled with the conveying belt 423, the conveying belt 423 can be placed in the limiting groove 721, and the opening of the limiting groove 721 towards the first clamping component 71 is covered by the first clamping component 71, so as to prevent the conveying belt 423 from being pulled out from between the first clamping component 71 and the second clamping component 72, and improve the stability of clamping.

[0065] Further, the length of the clamping rib 711 is greater than the width of the limiting groove 721. In this way, a part of the clamping rib 711 corresponds to the limiting groove 721, and another part of the clamping rib 711 corresponds to the edge portion of the limiting groove 721, so as to improve the uniformity of the stress of the conveying belt 423. It can be understood that during assembly, a part of the clamping rib 711 can clamp the conveying belt 423 in cooperation with the bottom wall of the limiting groove 721. At this time, due to the flexible nature of the conveying belt 423, the clamping force received by the conveying belt 423 at different positions is not uniform, which causes local fatigue damage of the conveying belt 423.
