[0039] 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.

[0040] 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.

[0041] Hereinafter, with reference to the accompanying drawings, a feeding assembly 10 according to an embodiment of the present invention will be described. The feeding assembly 10 is used for a testing device, and the testing device can be used for performing defect detection on a test piece. Figure 1 As shown, the detection device also includes a transmission component 20, and the transmission component 20 has a transmission direction (for example, Figure 1 The conveying assembly 20 can convey the part to be inspected along the conveying direction.

[0042] like Figure 3 and Figure 4 As shown, the loading assembly 10 includes a frame 1 and a first loading platform 2. The first loading platform 2 is disposed on the frame 1, and the first loading platform 2 can be moved along a first direction (for example, Figure 3 The first loading platform 2 can move relative to the frame 1 in a direction perpendicular to the conveying direction (in the up and down direction), and the first direction is perpendicular to the conveying direction. The first loading platform 2 is used to convey the part to be detected toward the conveying assembly 20. For example, the first loading platform 2 can move between a first loading position and a loading position. At the first loading position, the part to be detected can be conveyed to the first loading platform 2. The loading position is adjacent to the conveying assembly 20, and at the loading position, the part to be detected can be transferred to the conveying assembly 20. For example, the part to be detected can be transferred from the first loading platform 2 to the conveying assembly 20 through the clamping assembly 30 of the detection device.

[0043] The loading assembly 10 further includes a second loading platform 3, which is disposed on the frame 1, and the second loading platform 3 and the first loading platform 2 are suitable for being disposed on the conveying assembly 20 in the second direction (for example, Figure 1 and Figure 2 The same side of the front-to-back direction) can save the space occupied by the loading assembly 10 in the second direction and reduce the width of the loading assembly 10 in the second direction.

[0044] When the loading component 10 is used for detection equipment, the width of the detection equipment in the second direction can be effectively reduced, and the loading component 10 and the conveying component 20 can be both arranged in the box 50 of the detection equipment. In the second direction, a window can be provided on the side of the box 50 away from the loading component 10 for observation, maintenance, etc.; since the second loading table 3 and the first loading table 2 are suitable for being located on the same side of the conveying component 20 in the second direction, it is convenient to effectively reduce the distance between the window on the box 50 and the conveying component 20, thereby effectively improving the convenience for operators to inspect the conveying component 20 through the window, and facilitating the maintenance of the detection equipment.

[0045] The second loading platform 3 can move to a predetermined position relative to the first loading platform 2 to transfer the parts to be detected on the second loading platform 3 to the first loading platform 2. For example, the second loading platform 3 can move between the second loading position and the predetermined position. At the second loading position, the parts to be detected can be transferred to the second loading platform 3 by a conveying mechanism or by an operator. The second loading platform 3 drives the parts to be detected to move to the predetermined position, and the parts to be detected can be transferred from the second loading platform 3 to the first loading platform 2.

[0046] Therefore, the movement of the first loading table 2 and the second loading table 3 can be reasonably set. For example, the time taken by the first loading table 2 to move from the first loading position to the loading position can be used to transfer the parts to be inspected to the second loading table 3, etc., so as to realize continuous loading of the loading component 10 and effectively ensure the loading efficiency.

[0047] According to the loading component 10 of the embodiment of the present invention, by setting the first loading platform 2 and the second loading platform 3, the first loading platform 2 is used to convey the parts to be inspected toward the conveying component 20, and the second loading platform 3 is used to convey the parts to be inspected to the first loading platform 2, so as to facilitate the continuous loading of the loading component 10 and ensure the loading efficiency.

[0048] In addition, compared with some technologies, in which two loading tables are respectively arranged on different sides of the conveying component in the second direction, each loading table conveys the parts to be inspected toward the conveying component and allows the two loading tables to convey them alternately in sequence through two clamping components. In the present application, the first loading table 2 and the second loading table 3 are arranged on the same side of the conveying component 20 in the second direction, which can save the space occupied by the loading component 10 in the second direction. When the loading component 10 is used for detection equipment, the width of the detection equipment in the second direction is effectively reduced, and the distance between the maintenance window on the box 50 of the detection equipment and the conveying component 20 is reduced, thereby improving the maintenance convenience. Moreover, the loading component 10 in the present application can cooperate with a clamping component 30 to realize the continuous transmission of the parts to be inspected, which effectively simplifies the structure of the detection equipment and reduces the cost.

[0049] It can be understood that, at the predetermined position, the second loading platform 3 and the first loading platform 2 can move relative to each other in the first direction so that the parts to be detected on the second loading platform 3 can be transferred to the first loading platform 2. For example, when the second loading platform 3 moves to the predetermined position, the second loading platform 3 can remain stationary relative to the frame 1, and the first loading platform 2 can move relative to the frame 1 along the first direction, so that the first loading platform 2 can take away the parts to be detected on the second loading platform 3; for another example, when the second loading platform 3 moves to the predetermined position, the first loading platform 2 can remain stationary relative to the frame 1, and the second loading platform 3 can move relative to the frame 1 along the first direction, so that the parts to be detected on the second loading platform 3 can be transferred to the first loading platform 2.

[0050] The following description is made by taking the first direction as the up and down direction as an example: Figure 3-Figure 6 As shown, when the second loading platform 3 moves to a predetermined position (such as Figure 6 As shown in the figure, the second loading table 3 can remain stationary relative to the frame 1, and the first loading table 2 can move upward to take away the parts to be inspected on the second loading table 3; or, when the second loading table 3 moves to a predetermined position, the first loading table 2 can remain stationary relative to the frame 1, and the second loading table 3 can move downward. Due to the blocking effect of the first loading table 2, the parts to be inspected remain on the first loading table 2 and are separated from the second loading table 3.

[0051] In some embodiments, Figure 5 and Figure 6 As shown, the second loading table 3 can move along the conveying direction, so the movement mode of the second loading table 3 is simple, which is conducive to simplifying the structure of the loading assembly 10; moreover, since the moving direction of the second loading table 3 is perpendicular to the moving direction of the first loading table 2, it is convenient to ensure that the placement posture of the to-be-detected parts remains unchanged during the process of being conveyed from the second loading table 3 to the first loading table 2, thereby avoiding the deflection of the to-be-detected parts due to external forces during the above process, affecting the detection accuracy of the to-be-detected parts, and avoiding the friction of the to-be-detected parts and avoiding scratches on the to-be-detected parts.

[0052] For example, in Figure 1 and Figure 2 In the example, the two ends of the conveying component 20 in the conveying direction are respectively a first end and a second end, the first loading platform 2 is suitable for being arranged at the first end of the conveying component 20, and the second loading platform 3 moves between the second loading position and the predetermined position. At the second loading position, the second loading platform 3 and the conveying component 20 are staggered in the conveying direction, so that the second loading platform 3 extends to the side of the first end away from the back of the second end, which can reduce the occupation of the conveying component 20 on the surrounding space of the second loading platform 3, so that there is sufficient operating space around the second loading platform 3 to quickly load the second loading platform 3.

[0053] It is understandable that, at the second loading position, the offset distance between the second loading table 3 and the conveying assembly 20 in the conveying direction can be specifically set according to actual needs.

[0054] Of course, the movement mode of the second loading platform 3 is not limited thereto. For example, the second loading platform 3 may also be pivotally connected to the frame 1, and the second loading platform 3 may rotate between the second loading position and the predetermined position.

[0055] In some embodiments, Figure 6As shown, at a predetermined position, the second loading platform 3 and the first loading platform 2 are plugged into and arranged, which includes the following schemes: 1. At least part of the second loading platform 3 is plugged into the first loading platform 2, and the part of the second loading platform 3 plugged into the first loading platform 2 can be used to carry the parts to be inspected; 2. At least part of the first loading platform 2 is plugged into the second loading platform 3, and the part of the first loading platform 2 plugged into the second loading platform 3 can be used to receive the parts to be inspected transferred from the second loading platform 3; 3. At least part of the second loading platform 3 is plugged into the first loading platform 2, and at least part of the first loading platform 2 is plugged into the second loading platform 3, and the part of the second loading platform 3 plugged into the first loading platform 2 can be used to carry the parts to be inspected, and the part of the first loading platform 2 plugged into the second loading platform 3 can be used to receive the parts to be inspected transferred from the second loading platform 3. Therefore, at the predetermined position, it is convenient to ensure that the parts to be inspected are stably and smoothly transferred from the second loading platform 3 to the first loading platform 2 when the first loading platform 2 and the second loading platform 3 move relative to each other in the first direction.

[0056] In addition, since the second loading platform 3 is plugged into the first loading platform 2 at a predetermined position, the first loading platform 2 and the second loading platform 3 are close to each other in the first direction, which makes it convenient to arrange the driving device for driving the second loading platform 3 to move on the side of the second loading platform 3 away from the conveying component 20, and the driving device will not block or interfere with the movement of the first loading platform 2, which is beneficial to the reasonable layout of the loading component 10 and the conveying component 20; at the same time, compared with the first loading platform being located on the side of the second loading platform facing away from the conveying component at the predetermined position, the second loading platform 3 of the present application is plugged into the first loading platform 2 at a predetermined position, which can appropriately reduce the distance between the first loading platform 2 and the conveying component 20 in the first direction, reduce the moving distance of the first loading platform 2, and is beneficial to further improve the loading efficiency.

[0057] In some embodiments, Figure 6 and Figure 8 As shown, the first loading platform 2 includes a plurality of first support ribs 21 spaced apart along the second direction, and the second loading platform 3 includes a plurality of second support ribs 31 spaced apart along the second direction. At a predetermined position, the plurality of first support ribs 21 and the plurality of second support ribs 31 are staggered along the second direction. Then, at the predetermined position, one or more second support ribs 31 can be inserted between at least two adjacent first support ribs 21, and / or one or more first support ribs 21 can be inserted between at least two adjacent second support ribs 31, thereby further ensuring that the parts to be inspected are smoothly transferred from the second loading platform 3 to the first loading platform 2, and the second loading platform 3 will not interfere with the movement of the first loading platform 2.

[0058] It can be understood that the plurality of first support ribs 21 can be arranged at uniform intervals or at non-uniform intervals along the second direction; the plurality of second support ribs 31 can be arranged at uniform intervals or at non-uniform intervals along the second direction.

[0059] In addition, by configuring the first loading platform 2 to support the workpiece to be inspected by a plurality of first supporting ribs 21, the contact area between the first loading platform 2 and the workpiece to be inspected can be reduced, thereby reducing the risk of the first loading platform 2 scratching the workpiece to be inspected; configuring the second loading platform 3 to support the workpiece to be inspected by a plurality of second supporting ribs 31 can reduce the contact area between the second loading platform 3 and the workpiece to be inspected, thereby reducing the risk of the second loading platform 3 scratching the workpiece to be inspected.

[0060] In some embodiments, Fig. 9 As shown, in the second direction, the width of the first support rib 21 is x1, the spacing between two adjacent first support ribs 21 is y1, and x1 and y1 satisfy 0.38≤x1 / y1≤48, so that at least two first support ribs 21 can jointly support the parts to be detected, ensuring that the first loading platform 2 can stably support the parts to be detected, avoiding twisting, deflection, etc. of the parts to be detected, and ensuring that the parts to be detected always maintain their initial placement posture on the first loading platform 2.

[0061] Furthermore, 0.38≤x1 / y1<1 is conducive to further rationalizing the arrangement of the first supporting ribs 21, saving the material used for the first loading platform 2, and reducing the cost.

[0062] In some embodiments, Fig. 9 As shown, in the second direction, the width of the second support rib 31 is x2, the spacing between two adjacent second support ribs 31 is y2, and x2 and y2 satisfy 0.38≤x2 / y2≤48, so that at least two second support ribs 31 can jointly support the parts to be detected, ensuring that the second loading platform 3 can stably support the parts to be detected, avoiding twisting, deflection, etc. of the parts to be detected, and ensuring that the parts to be detected always maintain their initial placement posture on the second loading platform 3.

[0063] Furthermore, 0.38≤x2 / y2<1 is conducive to further rationalizing the arrangement of the second supporting ribs 31, saving the material used for the second loading platform 3, and reducing the cost.

[0064] Optionally, at the predetermined position, multiple first support ribs 21 and multiple second support ribs 31 are staggered one by one along the second direction, then at the predetermined position, a second support rib 31 is provided between two adjacent first support ribs 21, and a first support rib 21 is provided between two adjacent second support ribs 31, so that when the parts to be inspected are jointly supported by the multiple second support ribs 31 on the second loading platform 3, it is convenient to ensure that the parts to be inspected are also jointly supported by the multiple first support ribs 21 when they are transferred to the first loading platform 2, thereby not only ensuring the stable transfer of the parts to be inspected, but also ensuring the stability of the placement of the parts to be inspected on the second loading platform 3 and the first loading platform 2.

[0065] Optionally, in the second direction, the width of the first support rib 21 and the width of the second support rib 31 are both x, and at the predetermined position, the spacing between adjacent first support ribs 21 and second support ribs 31 in the second direction is z, 0.38≤z / x≤1.125, so that the parts to be inspected of different sizes can be smoothly transferred from the second loading platform 3 to the first loading platform 2, and the parts to be inspected are jointly supported on the first loading platform 2 by at least two first support ribs 21.

[0066] Optionally, in Fig. 9 In the example, each first support rib 21 includes a first body 211 and a first support member 212, the first support member 212 is arranged at the top of the first body 211, and the first support member 212 is used to directly carry the part to be detected, then the first support member 212 can separate the part to be detected from the first body 211 to directly contact the part to be detected, and the first support member 212 is a non-metallic member (such as a plastic member, etc.), which can further prevent the first loading platform 2 from scratching the part to be detected. Each second support rib 31 includes a second body 311 and a second support member 312, the second support member 312 is arranged at the top of the second body 311, and the second support member 312 is used to directly carry the part to be detected, then the second support member 312 can separate the part to be detected from the second body 311 to directly contact the part to be detected, and the second support member 312 is a non-metallic member (such as a plastic member, etc.), which can further prevent the second loading platform 3 from scratching the part to be detected.

[0067] In some embodiments, Figure 6 As shown, the second loading platform 3 can move relative to the first loading platform 2, and the first supporting ribs 21 and the second supporting ribs 31 extend along the moving direction of the second loading platform 3 to ensure smooth mating of the first loading platform 2 and the second loading platform 3 to achieve smooth transmission of the parts to be inspected.

[0068] It can be understood that the first support rib 21 extends along the moving direction of the second loading platform 3, which can mean that the extending direction of the first support rib 21 is parallel or non-parallel to the moving direction of the second loading platform 3. For example, there is a certain angle between the extending direction of the first support rib 21 and the moving direction of the second loading platform 3. At this time, the smooth mating of the first loading platform 2 and the second loading platform 3 can be ensured by reasonably setting the interval between adjacent second support ribs 31. The setting of the second support rib 31 is also the same, which will not be repeated here.

[0069] For example, in Figure 6 In the example, the first support rib 21 and the second support rib 31 both extend in a straight line along the moving direction of the second loading platform 3, which simplifies the structure of the first support rib 21 and the second support rib 31 and facilitates processing. Of course, one of the first support rib 21 and the second support rib 31 can also extend in a curve along the moving direction of the second loading platform 3.

[0070] In some embodiments, Figure 3-Figure 6 and Fig. 9 As shown, the first direction is the up and down direction, the first loading platform 2 can move from bottom to top toward the conveying component 20, and can also move from top to bottom away from the conveying component 20. At the predetermined position, the upper surface of the second loading platform 3 is located above the upper surface of the first loading platform 2. That is to say, at the predetermined position, the height position of the upper surface of the second loading platform 3 is higher than the height position of the upper surface of the first loading platform 2. Therefore, in the process of the second loading platform 3 driving the inspected part to move to the predetermined position, the first loading platform 2 is always located below the inspected part, which effectively avoids the first loading platform 2 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.

[0071] In some embodiments, Figure 3-Figure 6 As shown, the loading assembly 10 further includes a detection device 4, and there are multiple detection devices 4, and the multiple detection devices 4 are respectively used to detect whether the first loading platform 2 and the second loading platform 3 are placed with the parts to be detected, so as to facilitate the automatic loading of the loading assembly 10 without the need for frequent operations by operators. For example, the detection device 4 detects that the parts to be detected have been placed on the second loading platform 3, and determines that the loading is completed. If the detection device 4 determines that there are no parts to be detected on the first loading platform 2, the second loading platform 3 can move toward a predetermined position at this time to transfer the parts to be detected to the first loading platform 2.

[0072] Optionally, the detection device 4 is a fiber optic sensor, and when the piece to be detected is placed on the second loading table 3, the piece to be detected can block the light beam to change the optical properties of the light beam; or, the detection device 4 is a weight sensor, and when the piece to be detected is placed on the second loading table 3, the detection device 4 can measure the weight of the piece to be detected.

[0073] It is understandable that the setting position of the detection device 4 can be specifically set according to the actual application. For example, when the detection device 4 is a fiber optic sensor, the detection device 4 can be set on the frame 1 and corresponding to the second loading table 3.

[0074] For example, Figure 7 As shown, the second loading platform 3 also includes a bottom plate 32, which is arranged at the bottom of the plurality of second support ribs 31, and the bottom plate 32 is fixedly connected to the plurality of second support ribs 31, so that the plurality of second support ribs 31 move synchronously. The second loading platform 3 slides with the frame 1 through a sliding assembly 5, and the sliding assembly 5 includes a guide rail 51 and a slider 52, the guide rail 51 is fixed to the frame 1, and the slider 52 is fixed to the bottom of the second loading platform 3; the frame 1 is provided with a first driving device 8, the first driving device 8 is used to drive the second loading platform 3 to move, and includes a driving motor 81 and a ball screw mechanism 82.

[0075] Optionally, the second loading platform 32 includes a plurality of sub-loading platforms spaced apart along the second direction, so as to reduce the weight of each sub-loading platform and facilitate processing, movement and installation, and each sub-loading platform includes a plurality of second supporting ribs 31 and a sub-bottom plate connected to the bottom of the plurality of second supporting ribs 31. The following description is made by taking two sub-loading platforms as an example, and those skilled in the art can easily understand the technical solution of three or more sub-loading platforms.

[0076] One end of each sub-loading platform in the second direction cooperates with the frame 1 through a sliding assembly 5, and the other end is fixedly connected through a connecting seat 6 to ensure that the two sub-loading platforms move synchronously and smoothly. Among them, the two sliding assemblies 5 are respectively arranged at the two ends of the second loading platform 3 in the second direction, and the connecting seat 6 is formed into a U-shaped structure. The frame 1 is fixed with a guide member 7, and the guide member 7 cooperates with the inner side of the U-shaped structure defined by the connecting seat 6, so as to further ensure the smooth movement of the second loading platform 3.

[0077] Optionally, a buffer member 9 is provided on the side of the slider 52 facing away from the predetermined position, which can buffer the movement of the second loading platform 3 away from the predetermined position, thereby protecting the second loading platform 3 .
