Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a transfer component and detection device. Background Technology

[0002] With the development of industrial technology, various electronic devices now place higher demands on the processing precision of their products. Therefore, it is common practice to position the products to be processed before processing to facilitate high-precision machining. In traditional technology, the products to be processed must first enter an independent positioning station for calibration. After calibration, the products to be processed are then transferred to the target location by a transport device. Although this method can achieve the positioning function, the additional transport action can easily cause the products to shift, introducing positioning errors and reducing overall accuracy and efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a transfer component and a detection device to address the above problems.

[0004] This application provides a transfer assembly, which includes a transport component and a drive module. The drive module is connected to the transport component to drive the transport component to move. The transport component includes a base, a reference structure, and a positioning structure. The base has a first suction hole and a through hole. The reference structure is disposed on the base and includes at least two structural parts located on the side adjacent to the through hole, and forms a fixing position covering the through hole and the first suction hole. The positioning structure is movably disposed on the base and is used to hold a workpiece against the fixing position, so that the workpiece contacts the at least two structural parts of the reference structure located on the side adjacent to the through hole.

[0005] In the aforementioned transfer assembly, the transport component can move under the drive of the drive module to transport the workpiece to the target position. The transport component includes a positioning structure and a reference structure. The positioning structure is movably mounted on the base and is used to hold the workpiece in a fixed position, cooperating with the reference structure to position the workpiece. That is, the workpiece can be positioned at the transport component and move to the target position with it, eliminating additional handling actions and ensuring high positional accuracy of the transported workpiece, providing a foundation for high-precision machining.

[0006] Furthermore, the base also has a first adsorption hole and a through hole, both located in a fixed position, so the positioned workpiece can cover the first adsorption hole and the through hole. Thus, on the one hand, when the workpiece is positioned in the fixed position, it can be fixed relative to the base under the adsorption provided by the first adsorption hole, without the need for a positioning structure to provide fixation. Therefore, after positioning is completed, the positioning structure can be driven away from the workpiece, allowing the workpiece surface to be fully exposed to the outside, facilitating processing. On the other hand, since the positioned workpiece covers the through hole, a portion of the workpiece can also be exposed to the outside through the through hole for processing by external components, improving the comprehensiveness of processing.

[0007] This application also provides a detection device, which includes a detection component and a transfer component as described above. The through hole is disposed through a third direction. The detection component includes a first detection module and a second detection module. In the third direction, the first detection module, the transfer component, and the second detection module are arranged sequentially. Attached Figure Description

Detailed Implementation

[0018] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0019] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0024] See Figure 1 , Figure 1 The diagram shows an isometric view of a detection device provided in an embodiment of this application. The detection device 30 provided in an embodiment of this application includes a transfer component 10 and a detection component 20. The transfer component 10 is used to transport the workpiece to the detection field of view of the detection component 20. The detection component 20 is used to perform operations on the workpiece within its detection field of view, including but not limited to appearance inspection and dimensional measurement.

[0025] Please see Figures 2 to 4 The transfer assembly 10 provided in one embodiment of this application includes a transport component 11 and a drive module 12. The transport component 11 is used to carry the workpiece, and the drive module 12 is connected to the transport component 11 to drive the transport component 11 to move, so that the transport component 11 can transport the workpiece to the target position (i.e., within the detection field of view).

[0026] The transport component 11 includes a base 100, a reference structure 200, and a positioning structure 300. Both the reference structure 200 and the positioning structure 300 are located on the base 100 and cooperate to position the workpiece. The reference structure 200 includes at least two structural parts located on the adjacent sides of the through hole 102, and a fixed position 201 is formed in the reference structure 200. The workpiece at the fixed position 201 can contact the at least two structural parts of the reference structure 200 located on the adjacent sides of the through hole 102. The positioning structure 300 is movably located on the base 100 and is used to hold the workpiece against the fixed position 201, so that the workpiece contacts the at least two structural parts of the reference structure 200 located on the adjacent sides of the through hole 102. In other words, the positioning structure 300 can cooperate with the reference structure 200 to position the workpiece. Thus, the workpiece can be positioned at the transport component 11 and move to the target position with the transport component 11, eliminating additional handling actions and giving the transported workpiece high positional accuracy, providing a foundation for high-precision machining.

[0027] Furthermore, the base 100 has a first adsorption hole 101 and a through hole 102, and the fixing position 201 covers the through hole 102 and the first adsorption hole 101. Thus, on the one hand, when the workpiece is positioned at the fixing position 201, it can be fixed relative to the base 100 under the adsorption provided by the first adsorption hole 101, without the need for the positioning structure 300 to provide a fixing effect. Therefore, after positioning is completed, the positioning structure 300 can be driven away from the workpiece, allowing the workpiece surface to be fully exposed to the outside, facilitating processing. On the other hand, since the positioned workpiece covers the through hole 102, a portion of the workpiece (i.e., the portion aligned with the through hole 102) can also be exposed to the outside through the through hole 102 for processing by external components, improving the comprehensiveness of processing.

[0028] It is understandable that the first adsorption hole 101 is used to connect to the negative pressure generator. The negative pressure generator provides negative pressure adsorption to the fixed position 201 through the first adsorption hole 101, so as to fix the workpiece at the fixed position 201 relative to the base 100 through negative pressure adsorption.

[0029] Please see Figure 5 and Figure 6 Combined Figure 1In one embodiment, the through hole 102 is disposed through the third direction S3. The detection component 20 includes a first detection module 21 and a second detection module 22, which are arranged sequentially along the third direction S3. That is, the first detection module 21, the transfer component 10, and the second detection module 22 are arranged sequentially from top to bottom. The top of the workpiece is detected by the first detection module 21, and the second detection module 22 can detect the bottom of the workpiece through the through hole 102, thus achieving the purpose of comprehensive detection.

[0030] Please continue reading. Figure 5 In one embodiment, the through hole 102 is provided through along the third direction S3, and in the direction away from the fixed position 201 along the third direction S3, the cross-sectional size of at least a portion of the through hole 102 gradually increases. That is, the bottom of the through hole 102 has a larger cross-sectional size, which can improve the shooting angle of the second detection module 22 and facilitate the flexible detection of the second detection module 22.

[0031] Regarding the positioning structure 300, as one example, the positioning structure 300 can be constructed as a single-piece design. The positioning structure 300 has a motion function, and its motion direction intersects with the extension directions of at least two structural parts of the aforementioned reference structure 200 (such as the first reference member 210 and the second reference member 220, which will be mentioned below). Thus, the positioning structure 300 can push the workpiece in an inclined direction (such as the direction of the angle bisector of the angle between the first direction S1 and the second direction S2, which will be mentioned below) to simultaneously contact at least two structural parts of the aforementioned reference structure 200, thereby achieving positioning.

[0032] Of course, the positioning structure 300 may also include multiple movable positioning elements, which abut against the workpiece from different directions, so that the workpiece is accurately positioned at the fixed position 201 and in contact with the reference structure 200.

[0033] Please see Figure 4 Combined Figure 3 and Figure 7 In one embodiment, the positioning structure 300 includes a first positioning member 310 and a second positioning member 320. The first positioning member 310 and the second positioning member 320 are movably disposed on the base 100 along intersecting directions and are respectively positioned facing the reference structure 200 along their respective directions of movement. Thus, the first positioning member 310 and the second positioning member 320 can jointly push against the workpiece, so that the workpiece is accurately positioned in the fixed position 201.

[0034] Furthermore, the reference structure 200 includes a first reference member 210 and a second reference member 220. The first reference member 210 is disposed facing the first positioning member 310 in the direction of movement of the first positioning member 310, and the second reference member 220 is disposed facing the second positioning member 320 in the direction of movement of the second positioning member 320. That is, the first positioning member 310 and the first reference member 210 cooperate with each other to position the workpiece in one direction; the second positioning member 320 and the second reference member 220 cooperate with each other to position the workpiece in the other direction.

[0035] Please see Figure 4 In one embodiment, a first positioning member 310 is movably disposed on the base 100 along a first direction S1, and a second positioning member 320 is movably disposed on the base 100 along a second direction S2, wherein the first direction S1 and the second direction S2 intersect. Furthermore, the first direction S1 and the second direction S2 intersect a third direction S3, respectively. That is, when the first positioning member 310 moves along the first direction S1, it can cooperate with the first reference member 210 to clamp the workpiece in the first direction S1, thereby positioning the workpiece in the first direction S1. When the second positioning member 320 moves along the second direction S2, it can cooperate with the second reference member 220 to clamp the workpiece in the second direction S2, thereby positioning the workpiece in the second direction S2. Thus, the workpiece is completely positioned within the surface defined by the first direction S1 and the second direction S2 (i.e., the surface where the fixed position 201 is located on the base 100).

[0036] In one embodiment, the first reference member 210 may be configured to include a plurality of spaced-apart first reference portions (not shown in the figures, the same below) to reduce occlusion of the workpiece surface. Further, the plurality of first reference portions may be spaced-apart along the second direction S2.

[0037] Please see Figure 4 In one embodiment, the second reference member 220 may be configured to include a plurality of spaced-apart second reference portions 221 to reduce occlusion of the workpiece surface. Further, the plurality of second reference portions 221 may be spaced-apart along a first direction S1.

[0038] In one embodiment, the first direction S1 may be perpendicular to the second direction S2. Further, any two of the first direction S1, the second direction S2, and the third direction S3 may be perpendicular to each other.

[0039] In one embodiment, the first positioning member 310 and the second positioning member 320 can be configured to be connected by transmission, so that the first positioning member 310 can be driven to move along the first direction S1 while the second positioning member 320 moves synchronously along the second direction S2 by a single driving source, thereby simplifying the structure and reducing costs.

[0040] Please see Figure 3 In one embodiment, one of the first positioning member 310 and the second positioning member 320 has a linkage hole 301, and the other has a transmission pin 302. The transmission pin 302 passes through the linkage hole 301 and slides in engagement with the opposing side walls of the linkage hole 301. The extending directions of the opposing side walls of the linkage hole 301 intersect with both the first direction S1 and the second direction S2. Thus, the transmission pin 302 abuts against the inclined wall of the linkage hole 301, enabling the transmission of motion.

[0041] As one example, the linkage hole 301 can be formed in the first positioning member 310, and the second positioning member 320 has a transmission pin 302.

[0042] In one embodiment, the positioning structure 300 can also be configured to cooperate with the reference structure 200 to simultaneously position multiple workpieces. In this case, there are multiple first positioning members 310 and second positioning members 320. Alternatively, the first positioning members 310 and second positioning members 320 can also be configured to have multiple corresponding positioning parts (e.g., the first positioning part 312 and the second positioning part 322 mentioned below) to cooperate with the reference structure 200 to achieve batch positioning of multiple workpieces. It is understood that the number of first reference members 210 and second reference members 220 can also be configured to be multiple.

[0043] Please see Figure 7 The first positioning element 310 includes a first positioning part 312, and the second positioning element 320 includes a second positioning part 322. The first positioning part 312, the second positioning part 322, the first reference element 210, and the second reference element 220 cooperate with each other to position the workpiece 40. Furthermore, there are multiple first positioning parts 312, second positioning parts 322, first reference elements 210, and second reference elements 220 to correspondingly cooperate and position multiple workpieces 40.

[0044] Furthermore, the first positioning component 310 also includes a mounting plate 311, and multiple linkage holes 301 can be formed on the mounting plate 311. Multiple first positioning parts 312 are disposed on the mounting plate 311. Multiple second positioning parts 322 are correspondingly connected to multiple transmission pins 302. Multiple linkage holes 301 are correspondingly engaged with multiple transmission pins 302. Thus, by driving the mounting plate 311 to move, the multiple first positioning parts 312 can move as a whole, and drive the multiple second positioning parts 322 to move together, thereby cooperating with the reference structure 200 to position the workpiece.

[0045] Please see Figure 7 Combined Figure 4It is understood that multiple first positioning parts 312 are arranged at intervals along the reference direction S0, and multiple second positioning parts 322 are also arranged at intervals along the reference direction S0. A portion of the structure of the first positioning parts 312, the second positioning parts 322, and the reference structure 200 surrounding a fixed position 201 constitutes a positioning group, and multiple positioning groups are arranged at intervals along the reference direction S0. It is understood that a portion of the reference structure 200 constituting the positioning group may be a first reference member 210 facing the first positioning part 312 within the same positioning group, and a second reference member 220 facing the second positioning part 322 within the same positioning group.

[0046] Please continue reading. Figure 7 In one embodiment, the second positioning member 320 further includes a mounting base 321, and a plurality of second positioning parts 322 may be spaced apart along the reference direction S0 on the same mounting base 321. Alternatively, there may be a plurality of mounting bases 321, which are also spaced apart along the reference direction S0, and a plurality of second positioning parts 322 are correspondingly provided on the plurality of mounting bases 321.

[0047] As one example, the reference direction S0 can be parallel to the first direction S1.

[0048] Please see Figure 5 and Figure 7 In one embodiment, the base 100 includes a first guide rail 140 and a second guide rail 150, the first guide rail 140 extending along a first direction S1 and the second guide rail 150 extending along a second direction S2. The mounting plate 311 is slidably engaged with the first guide rail 140, and the mounting base 321 is slidably engaged with the second guide rail 150.

[0049] Furthermore, when there are multiple mounting bases 321, the number of second guide rails 150 can also be configured to be multiple, with multiple mounting bases 321 corresponding to multiple second guide rails 150 in sliding engagement.

[0050] Please see Figure 5 , Figure 7 and Figure 8 In one embodiment, the carrier component 11 further includes a driver 400 and a first elastic element 500. The driver 400 and the first elastic element 500 are both disposed on the base 100 and are respectively connected to the positioning structure 300 so as to drive the positioning structure 300 to move in opposite directions.

[0051] The driver 400 can be connected to the mounting plate 311 to drive a plurality of first positioning parts 312 to move away from the first reference member 210, and drive the second positioning parts 322 to move away from the second reference member 220. This allows the positioning assembly to be in an open state, facilitating the insertion or removal of workpieces from the fixing position 201.

[0052] The first elastic element 500 is also connected to the mounting plate 311. After the driver 400 removes the driving force, the first elastic element 500 can reverse the driving force of the mounting plate 311, causing the first positioning part 312 to move towards the first reference member 210, and driving the second positioning part 322 to move towards the second reference member 220. This allows the positioning assembly to be clamped, thereby positioning the workpiece at the fixed position 201.

[0053] Furthermore, the driver 400 can drive the first positioning member 310 to move along the first direction S1 and drive the second positioning member 320 to move along the second direction S2.

[0054] Please see Figure 7 and Figure 8 In one embodiment, the positioning structure 300 further includes a connector 330 connected to the mounting plate 311. In the first direction S1, the driver 400 is located on one side of the connector 330 and connected to the connector 330. A first elastic member 500 abuts against the opposite side of the connector 330 to reverse-drive the connector 330 to move when the driver 400 does not apply force.

[0055] Please see Figure 8 In one embodiment, the driver 400 and the first elastic element 500 may be located on the side of the base 100 facing away from the reference structure 200.

[0056] Please refer to it again. Figure 5 In one embodiment, the base 100 further includes a fixing seat 130 located on the side of the second positioning member 320 away from the second reference member 220. The transport component 11 also includes a second elastic member 600, which abuts between the second positioning member 320 and the fixing seat 130, so as to jointly drive the second positioning member 320 toward the second reference member 220 with the force transmitted by the first positioning member 310.

[0057] It should be noted that the transfer assembly 10 provided in the embodiments of this application can also be used to transport workpieces with relatively irregular overall structures. Please refer to... Figure 9As one example, workpiece 40 may include a first part 41 and a second part 42 connected to each other, wherein the first part 41 is a relatively rigid structure, and the second part 42 has a certain degree of flexibility. For example, the second part 42 may be configured as a flexible element such as a flexible circuit board and connected to the relatively rigid first part 41. The positioning of workpiece 40 described in the embodiments of this application may refer to driving the first part 41 to a desired position, and causing the second part 42 to be in the desired position accordingly, so as to achieve the positioning purpose. It is understood that the second part 42 may be located outside the fixed position 201.

[0058] Please see Figure 4 In one embodiment, the first adsorption hole 101 is located within the fixing position 201 and is used to be covered by the first portion 41 of the workpiece 40 to adsorb and fix the first portion 41 after positioning is completed. The base 100 also has a second adsorption hole 103, which is used to be covered by the second portion 42 to adsorb and fix the second portion 42 after positioning is completed, thereby achieving complete positioning of the workpiece 40. The distribution position of the second adsorption hole 103 can be set according to the specific shape of the workpiece 40, and this application does not limit it.

[0059] In one embodiment, the first adsorption pore 101 and the second adsorption pore 103 can be interconnected.

[0060] It is readily understood that, since the first part 41 and the second part 42 of workpiece 40 are directly connected, the second part 42 may block or interfere with the positioning structure 300's contact with the first part 41. For a solution to this problem, please refer to... Figure 7 Combined Figure 4 and Figure 5 In one embodiment, the first positioning member 310 is stacked on the side of the second positioning member 320 away from the base 100 in the third direction S3. Along the third direction S3, the first positioning member 310 and the surface of the base 100 where the fixed position 201 is located have a preset distance. Thus, the first positioning member 310 can cross the position of the second part 42 to directly act on the first part 41, thereby positioning the first part 41. Simultaneously, the stacked arrangement of the first positioning member 310 and the second positioning member 320 facilitates the insertion of the linkage hole 301 and the transmission pin 302 to form a transmission engagement.

[0061] Furthermore, a portion of the surface of the base 100 where the fixing position 201 is located is recessed to form a receiving groove 104, and at least one position of the first positioning member 310 in the direction of movement is above the receiving groove 104. The receiving groove 104 can be used to accommodate the second part 42, so that the first positioning member 310 can pass over the position where the second part 42 is located to directly act on the first part 41, thereby achieving the positioning of the first part 41.

[0062] Of course, the distribution area of ​​the receiving groove 104 can be adjusted as needed so that at least one position of the second positioning member 320 in the direction of movement is also above the receiving groove 104.

[0063] Please see Figure 5 and Figure 7 In one embodiment, the base 100 further includes a platform 110 and a fixture 120. The platform 110 has a connecting portion 111 and an extension portion 112. The connecting portion 111 is connected to the drive module 12, and the extension portion 112 extends outward relative to the drive module 12. The fixture 120 is disposed on the top surface of the extension portion 112, and the reference structure 200 is disposed on the fixture 120, i.e., the fixing position 201 is formed on the fixture 120. The first suction hole 101 and the second suction hole 103 are both formed in the fixture 120 to communicate with the area where the fixing position 201 is located. The first positioning member 310 and the second positioning member 320 are also disposed in the extension portion 112 to cooperate with the reference structure 200 to position the workpiece. Further, a through hole 102 is formed in the fixture 120 and extends through the platform 110. Because the protrusion 112 of the platform 110 extends relative to the drive module 12, the second detection module 22 can detect the workpiece on the top surface of the platform 110 without obstruction through the through hole 102. In this embodiment, the top surface refers to the side of the base 100 near the top in the third direction S3. In each embodiment, the surface where the fixing position 201 of the base 100 is located is the top surface of the fixture 120 in the third direction S3.

[0064] In one embodiment, the fixing seat 130 is also provided on the extension 112 of the platform 110.

[0065] Please refer to it again. Figure 1 In one embodiment, the drive module 12 can drive the carrier component 11 to move along the first direction S1. Of course, the carrier component 11 can also move along other directions under the drive module 12, which will not be described in detail here.

[0066] In one embodiment, the drive module 12 can be configured as a linear drive module such as a linear motor module and a conveyor belt module, and the driver 400 can be configured as a linear drive element such as a linear motor, a cylinder, and a hydraulic cylinder.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
