[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0044] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will appreciate the applicability of other processes and / or the use of other materials.

[0045] Hereinafter, referring to the accompanying drawings, a loading platform 200 according to an embodiment of the present invention will be described. The loading platform 200 is used for a testing device, and the testing device can be used to perform defect detection on a workpiece to be tested.

[0046] like Figure 1As shown, the loading station 200 includes a first direction (eg, Figure 1 A plurality of support ribs 101 are arranged at intervals along the front-to-back direction in the second direction (for example, Figure 1 The first direction and the second direction extend in the left and right directions, and the first direction and the second direction are perpendicular.

[0047] Among them, in the first direction, the width of the support rib 101 is x, the spacing between two adjacent support ribs 101 is y, and x and y satisfy 0.38≤x / y≤48, so that at least two support ribs 101 can jointly carry the parts to be detected, ensuring that the loading platform 200 can stably carry 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 loading platform 200. When the loading platform 200 is used for detection equipment, it is beneficial to ensure the detection accuracy of the detection equipment.

[0048] For example, any part to be inspected whose width in the first direction is greater than or equal to 50 mm can be applied to the loading table 200 of the present application; for example, the width of the part to be inspected in the first direction is 50 mm, the width of the support member 101 is 8 mm, and the spacing between two adjacent support ribs 101 is in the range of 0.16 mm to 21 mm, which can enable at least two support ribs 101 to jointly support the part to be inspected, and for parts to be inspected with a width greater than 50 mm, it can also be ensured that at least two support ribs 101 jointly support the part to be inspected.

[0049] According to the loading platform 200 of the embodiment of the present invention, by being arranged in the first direction, the ratio of the width x of the support rib 101 to the spacing y between two adjacent support ribs 101 satisfies 0.38≤x / y≤48, so that at least two support ribs 101 jointly carry the parts to be inspected, thereby ensuring that the loading platform 200 stably carries the parts to be inspected. At the same time, the loading platform 200 can be suitable for parts to be inspected of different widths and has good applicability.

[0050] In addition, by setting the loading platform 200 to support the parts to be tested by multiple support ribs 101, the contact area between the loading platform 200 and the parts to be tested can be reduced, reducing the risk of the loading platform 200 scratching the parts to be tested, thereby protecting the parts to be tested and reducing the material usage and weight of the loading platform 200.

[0051] It is understandable that the plurality of support ribs 101 may be arranged at uniform intervals or at non-uniform intervals along the first direction.

[0052] In some embodiments, x and y further satisfy: 0.38≤x / y<1, which is beneficial to further rationalize the arrangement of the support ribs 101, save the material used in the loading platform 200, and reduce costs.

[0053] In some embodiments, as Figure 1 As shown, each support rib 101 includes a main body 101a and a support member 101b. The support member 101b is arranged on the top of the main body 101a, and the support member 101b is used to directly support the part to be detected. The support member 101b can separate the part to be detected from the main body 101a so as to directly contact the part to be detected. The support member 101b is a non-metallic part (for example, a plastic part, etc.), which can further prevent the loading platform 200 from scratching the part to be detected.

[0054] According to the loading assembly 10 of the embodiment of the second aspect of the present invention, the loading assembly 10 is used for a detection device, and the detection device further includes a conveying assembly 20, which can convey the part to be detected along the second direction.

[0055] like Figure 4 and Figure 5 As shown, the loading assembly 10 includes a frame 1, a first loading platform 2 and a second loading platform 3. At least one of the first loading platform 2 and the second loading platform 3 is the loading platform 200 according to the first embodiment of the present invention, and the following schemes are included: 1. The first loading platform 2 is the loading platform 200 according to the first embodiment of the present invention; 2. The second loading platform 3 is the loading platform 200 according to the first embodiment of the present invention; 3. The first loading platform 2 and the second loading platform 3 are both the loading platform 200 according to the first embodiment of the present invention.

[0056] The first loading platform 2 and the second loading platform 3 are respectively movably provided on the frame 1. The first loading platform 2 can move relative to the frame 1 to transfer the parts to be inspected toward the conveyor 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 parts to be inspected can be transferred to the first loading platform 2. The loading position is adjacent to the conveyor assembly 20. At the loading position, the parts to be inspected can be transferred to the conveyor assembly 20. For example, the parts to be inspected can be transferred from the first loading platform 2 to the conveyor assembly 20 by the clamping assembly 30 of the inspection device.

[0057] The second loading platform 3 can be moved relative to the first loading platform 2 to a predetermined position to transfer the parts to be inspected on the second loading platform 3 to the first loading platform 2. For example, the second loading platform 3 can be moved between a second loading position and a predetermined position. At the second loading position, the parts to be inspected 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 inspected to the predetermined position, and the parts to be inspected can be transferred from the second loading platform 3 to the first loading platform 2.

[0058] Therefore, the movement of the first loading platform 2 and the second loading platform 3 can be reasonably set. For example, the time for the first loading platform 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 platform 3, etc., so as to realize continuous loading of the loading component 10 and effectively ensure the loading efficiency; moreover, by adopting the above-mentioned loading platform 200, the applicability of the loading component 10 can be improved, so that the loading component 10 can be applicable to parts to be inspected with a wider size range.

[0059] In some embodiments, as Figure 4-Figure 7 As shown, the first loading station 2 can be arranged along a third direction (eg, Figure 4 The third direction is perpendicular to the first direction and the second direction respectively, so the movement mode of the first loading table 2 is simple, which is conducive to simplifying the structure of the loading assembly 10.

[0060] Among them, such as Figure 2 and Figure 3 As shown, the second loading platform 3 and the first loading platform 2 are suitable for being arranged on the conveying assembly 20 in the first direction (for example, Figure 2 The same side of the front-to-back direction) can save the space occupied by the loading assembly 10 in the first direction and reduce the width of the loading assembly 10 in the first direction.

[0061] When the loading assembly 10 is used for the detection equipment, compared with some technologies, the two loading tables are respectively arranged on the opposite sides of the conveying assembly in the second direction, each loading table conveys the workpiece to be detected toward the conveying assembly and the two loading tables are alternately conveyed in sequence through the two clamping assemblies. The loading assembly 10 of the present application can effectively reduce the width of the detection equipment in the first direction, such as Figure 11 and Figure 12 As shown, the loading component 10 and the conveying component 20 can both be arranged in the box body 50 of the detection equipment. In the second direction, a window can be provided on the side of the box body 50 away from the loading component 10 for observation, maintenance, etc. Since the second loading platform 3 and the first loading platform 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 body 50 and the conveying component 20, effectively improving the convenience of the operator to inspect the conveying component 20 through the window, etc., and facilitating the maintenance of the detection equipment. Moreover, the loading component 10 in the present application can cooperate with a clamping component 30 to realize continuous transmission of the parts to be detected, effectively simplifying the structure of the detection equipment and reducing costs.

[0062] It is understandable that, at the predetermined position, the second loading platform 3 and the first loading platform 2 can move relative to each other in the third direction so that the parts to be inspected 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 third direction, so that the first loading platform 2 can take away the parts to be inspected 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 third direction, so that the parts to be inspected on the second loading platform 3 can be transferred to the first loading platform 2.

[0063] The following is an explanation taking the third direction as the up and down direction as an 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 upward to take away the parts to be inspected on the second loading platform 3; or, when the second loading platform 3 moves to the predetermined position, the first loading platform 2 can remain stationary relative to the frame 11, and the second loading platform 3 can move downward. Due to the blocking effect of the first loading platform 2, the parts to be inspected remain on the first loading platform 2 and are separated from the second loading platform 3.

[0064] In some embodiments, as Figure 4-Figure 7 As shown, the second loading station 3 can be arranged along the second direction (eg, Figure 4 and the first loading platform 2 is moved in a direction perpendicular to the direction of the movement of the second loading platform 3. This facilitates ensuring that the placement of the inspected parts remains unchanged during the process of being transferred from the second loading platform 3 to the first loading platform 2, thereby avoiding deflection of the inspected parts due to external forces during the above process, thereby affecting the inspection accuracy of the inspected parts, and preventing the inspected parts from being subjected to friction and being scratched.

[0065] For example, in Figure 2 and Figure 3 In the example, the two ends of the conveying component 20 in the second direction are respectively the first end and the 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 second 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.

[0066] It is understandable that, at the second loading position, the offset distance between the second loading platform 3 and the conveying assembly 20 in the second direction can be specifically set according to actual needs.

[0067] Of course, the movement mode of the second loading platform 3 is not limited thereto. For example, the second loading platform 3 can also be pivotally connected to the frame 1, and the second loading platform 3 can rotate between the second loading position and the predetermined position.

[0068] In some embodiments, as Figure 7 As shown, at a predetermined position, the second loading platform 3 and the first loading platform 2 are plugged and arranged, which includes the following solutions:

[0069] 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 that is plugged into the first loading platform 2 can be used to carry the parts to be inspected; for example, the second loading platform 3 is the loading platform 200 according to the above-mentioned first aspect of the embodiment of the present invention, and includes a plurality of second support ribs 31 arranged at intervals along the first direction, and the plurality of second support ribs 31 can be plugged into the first loading platform 2.

[0070] 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 that is plugged into the second loading platform 3 can be used to receive the parts to be inspected transferred from the second loading platform 3; for example, the first loading platform 2 is the loading platform 200 according to the first embodiment of the present invention, and includes a plurality of first support ribs 21 spaced apart along the first direction, and the plurality of first support ribs 21 can be plugged into the second loading platform 3.

[0071] 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. The part of the second loading platform 3 that is 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 that is plugged into the second loading platform 3 can be used to receive the parts to be inspected transferred from the second loading platform 3; for example, the first loading platform 2 and the second loading platform 3 are both the loading platforms 200 according to the above-mentioned first aspect embodiment of the present invention, and the first loading platform 2 includes a plurality of first support ribs 21 spaced apart along the first direction, and the second loading platform 3 includes a plurality of second support ribs 31 spaced apart along the first direction.

[0072] Thus, 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.

[0073] 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 set 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 conducive 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 setting of the second loading platform 3 in 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 help to further improve the loading efficiency.

[0074] In some embodiments, as Figures 6-10 As shown, the first loading platform 2 and the second loading platform 3 are both loading platforms 200 according to the first embodiment of the present invention. 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. In the first direction, the width of the first support rib 21 is x1, and the spacing between two adjacent first support ribs 21 is y1, 0.38≤x1 / y1≤48. In the first direction, the width of the second support rib 31 is x2, and the spacing between two adjacent second support ribs 31 is y2, 0.38≤x2 / y2≤48.

[0075] At the predetermined position, multiple first support ribs 21 and multiple 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.

[0076] 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.

[0077] Optionally, at a predetermined position, a plurality of first support ribs 21 and a plurality of second support ribs 31 are staggered one by one along the second direction, then at a 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 plurality of 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 plurality of 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.

[0078] In some embodiments, as Figure 10 As shown, in the first direction, the width of the first support rib 21 and the width of the second support rib 31 are both x. At the predetermined position, the spacing between adjacent first support ribs 21 and second support ribs 31 in the first 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.

[0079] In some embodiments, as Figure 6 and Figure 7 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, thereby achieving smooth transmission of the parts to be inspected.

[0080] It is understood that the first support ribs 21 extending along the movement direction of the second loading platform 3 can mean that the extension direction of the first support ribs 21 is parallel or non-parallel to the movement direction of the second loading platform 3. For example, there is a certain angle between the extension direction of the first support ribs 21 and the movement direction of the second loading platform 3. In this case, the spacing between adjacent second support ribs 31 can be reasonably set to ensure smooth mating of the first loading platform 2 and the second loading platform 3. The arrangement of the second support ribs 31 is also similar and will not be repeated here.

[0081] For example, in Figure 6 and Figure 7 In the example, both the first support rib 21 and the second support rib 31 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 curved line along the moving direction of the second loading platform 3.

[0082] In some embodiments, as Figure 7 、 Figure 9 and Figure 10As shown, the third direction is the up and down direction. The first loading platform 2 can move from bottom to top toward the conveying component 20, or 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 ensured to be located below the inspected part, effectively avoiding the first loading platform 2 applying friction resistance to the inspected part, causing scratches on the inspected part, or causing the inspected part to be deflected, etc., thereby ensuring the smooth and smooth transmission of the inspected part.

[0083] In some embodiments, as Figure 4-Figure 7 As shown, the loading assembly 10 also includes a detection device 4, which is used to detect whether the second loading platform 3 is placed with the part to be inspected. This facilitates automatic loading of the loading assembly 10 without the need for frequent operator operation. For example, the detection device 4 detects that the second loading platform 3 has placed the part to be inspected, and determines that loading is complete. If the detection device 4 determines that the first loading platform 2 does not have the part to be inspected, the second loading platform 3 can move toward a predetermined position to transfer the part to be inspected to the first loading platform 2.

[0084] Optionally, the detection device 4 is a fiber optic sensor, and when the piece to be detected is placed on the second loading platform 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 platform 3, the detection device 4 can measure the weight of the piece to be detected.

[0085] 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 platform 3.

[0086] For example, Figure 8 As shown, the second loading platform 3 also includes a base plate 32, which is located at the bottom of the multiple support ribs 31 and is fixedly connected to the multiple second support ribs 31 to enable the multiple second support ribs 31 to move synchronously. The second loading platform 3 slides with the frame 1 via a sliding assembly 5. 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.
